The method is something like this: -keyDown: (NXEvent *)theEvent { //Investigation of values of theEvent->flags and NX_CONTROLMASK NXLogError("flag=%d mask=%d\n",theEvent->flags,NX_CONTROLMASK); if (theEvent->flags & NX_CONTROLMASK) NXlogError("control down"); else NXLogError("control not down"); return self; } The result is that when I press Control (or Alternate, or Shift), nothing happens at all (which means my pressing down of these keys was not recognized as a keyDown event?), and when I press anything else, I (of course) get "control not down" and "flag=0 mask=24301". This has been giving me a headache for hours. Could anyone out there give me a hand? Thanks alot. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Ye he@carnegie.swarthmore.edu (NeXTmail OK)

The problem is that the view is originally something like 300 by 300 and the size that I need varies. I set my view's drawing size, at first with [self setDrawSize:x:y]; and then with [self scale:bounds.size.width/x: bounds.size.height/y]; but when I get the mouse y coord, it still gives me a range from 100 to 400, instead of the range that I set. I even did [self convertPoint:&pt fromView:self] in my mouseDown method. Is there anyway to change the definition of a 'point' for a certain view? Christopher seawoocl@nextwork.rose-hulman.edu

Newsgroups: comp.sys.next.programmer From: erwin@helsinki.ks.uiuc.edu (Edgar Erwin) Subject: Mouse Event Problems Date: Wed, 30 Jun 1993 23:34:54 GMT Message-ID: <C9GK66.ErL@news.cso.uiuc.edu> Sender: usenet@news.cso.uiuc.edu (Net Noise owner) Organization: University of Illinois at Urbana Hey all you happy people! I have a problem involving a slider and a mouse. The program is doing some computations using values from sliders as parameters. Sometimes when the user changes a parameter (through a slider) the computations can blow up -- either very soon after the parameter is changed, or much later --- and the user is alerted through an AlertPanel. After the user admits to the alert panel that he did in fact make a boo-boo, the slider is reset to a more reasonable value and the computations continue. The way this is programmed looks something like this: - iterate { // iterate is called at regular intervals, beyond the control of the user .. if (fabs(X) > 3.0) { NXRunAlertPanel("Boom!", "Equations blew up: resetting.", "OK", 0, 0); B = 0.3; [myBField setDoubleValue:B]; [myBSlider setDoubleValue:B]; } .. } Usually, this works just fine. However, if the user still has his finger on the mouse button on the slider when the equations blow up, problems arise. The user will generally let go of the mouse button on the slider, move the mouse to the AlertPanel and click the "OK" button. The next time the user tries to move the slider, or in fact do just about anything else involving the mouse, he will notice the mouse acts funny. It is hard to describe exactly what happens, but my theory is that when the user presses the mouse button anywhere, the mouseDown doesn't go anywhere for the time being, but when he releases the button, the mouseUp event goes back to the place where the next-to-last mouseDown occurred, and only afterwards will the current mouseDown go where it should. This continues to cause problems until the user clicks someplace that doesn't respond to the mouseDown event which then allowins the mouseDown event to be ignored and the mouseUp event to be used, thus re-synchronizing the event queue, but the problem can arise again the next time the equations blow up. The problem obviously has something to do with trying to change the value of a slider field when the user might not have let go of the slider yet. Anyone have ideas for a solution? Is there any way to let the slider know to stop waiting for a mouseUp so that it won't be stealing mouseUp's from wherever it can find one? Suggestions that I should prevent the user from sliding the slider into a danger zone are not welcome. It isn't that easy. Thanks in advance.

Thanks to Jim Beauchamp <beaucham@uxh.cso.uiuc.edu> and David Jaffe <david@jaffe.com> for their responses. Also, thanks to Len Manzara, our local NeXT music expert, for his help. There were no conflicting reports; all the answers more or less supported each other. The solution to producing realistic music is _not_ to record it and play it back. It's too troublesome and difficult and can result in funny problems, such as waves getting cut in half and whatnot. Realistic music is, however, very possible. I'm sure all of you have heard demo score files, and Ensemble seems to be the definitive place to play with creating instruments. The music can be generated to very precise amounts of time, restricted by the sampling rate and what David Jaffe calls "envelope break-points times." He estimates 0.0003 second response time, more than enough for my purposes. How did the MusicKit measure up to MIDI. Everyone I talked to claims the MusicKit will give equal if not better control of the sound parameters than MIDI will as well as more flexibility. The MusicKit's one failing point was that there was not a well-made well-packaged set of realistic sample instruments. Following suggestions and the MusicKit manual, the best I could find were some sample score files from which I gleaned the following instrument parameters: clarinet, cello, bell, wind, flute, drum, bass, kalimba, conga, and gong. Unfortunately, to my (admittedly untrained) ear, many did not sound much like the instrument they were named after. This was an important requirement that MIDI was able to meet, and certainly not one I expected the MusicKit to fail. Including good sample instruments in the MusicKit seemed like an obvious thing to do. So, for those of you who are willing to go to great lengths for great music, it seems the MusicKit beats out all but the high-end MIDI boxes. For those of you looking to create simple, but realistic music, the MIDI box seems to provide what you need more easily. Thanks once again for all your help. - David Marwood - marwood@cpsc.ucalgary.ca

The good news is that it seems to work ok, which is great, as it means that it will be possible to use a much better C++ implementation than before without giving up gdb. The second piece of good news is that gcc-2.4.5 compiles without a single warning. The not so good news is that libg++-2.4 needs some fiddling. It seems that there has been some more changes in NeXT's headers (probably for the better)...

If it's from a bundle, the problem is with the linker optimizing the library out of the link becuase it can't find any references to it. When the bundle is loaded, the application suddenly needs the library which, of course, isn't there. I would just leave the LDFLAGS as you have them. Don't know if this helps, but it's a guess anyway. Cheers, brian -- Brian Cuthie Voice: (410) 290-8813 Systemix Software, Inc. Email: brian@systemix.com

Decreasing numcoords-values by 6 and numOps by 3 all works fine. I think what's happening is that you're drawing outside the bounding box you've passed in. When that happens with DPSDoUserPath() the WindowServer will raise an exception. The weenie way around this is to make a huge bounding box. I don't know of any other solutions. - db -- <Here we are!

But I agree with gregory what I want is a real code browser like Smalltalk that is organized into classes and method categories and methods. The biggest problem with the smalltalk browser might be having to be backward comp. with source files. One typically makes #defines and static funcs in misc places in a source file. Where would these go? The only solution I see is to have the definition for a method and have a ``before'' and ``after'' button which allows you to place code either before or after the method declaration once the source stream needed for compilation is generated. I am doing some rapid prototyping to see what some of the concerns would be in such a browser. Would I don't like is the lack of view sensitive popup windows like smalltalk's for manipulating individual columns of group/class/category/method definition lists. I wrote a hack PopUpMenu class (on sonata) which violates every NS interface guideline but does the job, but it looks like to much trouble to have to redefine a NXBrowser class to get the menu instance variables into the act..... gregory gbol@rglnext.geol.vt.edu gbol@shell.com

After that, all bets are off. In our classes, we don't always write to the stream in the same order that ivars are declared in the header, and sometimes not all ivars need to be written. Plus, there's a difference between NXWriteType(stream,"s",&version); NXWriteType(stream,"s",&owner); and NXWriteTypes(stream,"ss",&version,&owner); and you never know which method an author chose. Bit-fields might be written as one big int or (the better way for architecture neutrality) a bunch of chars. Plus, world-class object writers (8^) include embedded version numbers, as in the example above, that are not represented by ivars at all. The whole idea of encapsulation is that only the class that reads and writes the data needs to know the details about this stuff. Not to mention that NXTypedStreams are thoroughly impenetrable: a private specification, not formally documented, has changed over time, and is subject to change again without notification in any future release if Paul Hegarty gets a better idea, of which he has had plenty.

Date: Thu, 1 Jul 1993 13:45:16 +0000 Message-ID: <1993Jul1.134516.3325@prim> Sender: usenet@demon.co.uk I've got a really wierd problem that's only just started happening. Basically, the first time I try to compile a new .m file, I get a load of errors of the type you would expect if you'd forgotten to include a #import directive. But the #import is there, and so is the header file it refers to. I'm not using precompiled headers. The header file in question was actually brought into the project as a result of dragging the class icon in Project Builder from another project's class suitcase. I'm not sure if this is related to the problem. Doing a "make depend" and a "make clean" doesn't help. The header file is there, the #import is there, but the compiler acts as though the header file is empty! The header file is not a link of any kind. Now here's the wierd part: I can make the problem go away by opening the header file in Edit and just saving it without changing it. Hey presto, the compiler now recognizes it and the problem disappears! Anyone know what could be causing this? Dave Griffiths

Message-ID: <1993Jul1.191755.644@houston.dolphin.com> Keywords: Version-Control Sender: jcr@houston.dolphin.com Organization: Dolphin Software Date: Thu, 1 Jul 1993 19:17:55 GMT Would any of you care to coment on the following? This is the current state of my idea of how to organize Objective-C code, Replace PB, replace Make, and make the world a happier place. Greg and Jon at AFS, Andy Stone, Glenn Ried, I'd be especially interested in what you think of it. A Modest Proposal Thoughts about a different way to organize Objective-C, Display Postscript, and other source code under NEXTSTEP. Part One: Wouldn't it be Nice If: When developing Objective C code, we could browse the classes, in the manner of HeaderViewer, and open just the method we're interested in? No hunting through the source file, no looking back through the heirarchy to find the method (if it's inherited)? or: we were able to edit a method, compile and run it, but still take back the changes we made, if something we try doesn't work? What I'd like to see when writing a class: I propose a new type of file package, which would contain the source code, documentation, and version control information for a single class. This package would have the extension ".Class" and would typically contain the following: myClass.class/ Class Package /inheritance file containing: "superClass<version Number>" /version.<original>/ Version directory /myClass.doc documentation for this class /uses Include files. /myClass.otherSources/ Common PSwraps, etc. /myClass.nibSection Window used by this class. /version.<last>/ Version directory /version.<current>/ Version directory /myClass.h Header file for external interface /myClass.private.h Header file for methods of myClass /uses Include files: supersedes the one in /version.<original> /someMethod.method/ Method Package /someMethod.m Source for one method /obj/machine/someMethod.o Compiled method /someMethod.doc Documentation of this method /someMethod.othersources Directory of other files needed by this method. /drawingCode.psw PSWrap used only by this method. This re-organization of the source code of a class brings many advantages. First of all, the directory structure allows for a very simple implementation of version control. Secondly, seperating the methods into their own .m files allows much smaller increments to be compiled and debugged. Third, the supporting files, such as .nib files or .psw files can be logically grouped with the class or method which uses them. Without going into a long discussion of version control, suffice it to say that we envision a directory (such as, perhaps "/LocalDeveloper/Classes", which can have any number of classes, and versions of those classes, with the ability for the Individual developer to branch away from the central depository at any version of the class. In addition, if one person is developing a class, and another person is developing a subclass of that class, the person working on the subclass could select a particular version of the superclass to link to, and would be unaffected by changes being made by the other developer. NeXT likes to point out that IB is aware of objects, where other user interface tools are not. However, this is not the case with the rest of the development tools. What if our compiler/editor/linker combination knew about classes? What if the editor could load the interface for the superclass, and generate skeleton methods to override the inherited methods? something like: Or, suppose we could set the compile options for each method by checking boxes in a method inspector. Now, Stepping out a bit farther, let's look at how we would arrange a project. Obviously, if we have a ".Class" package, it makes sense to apply the same idea to projects, vis: MyApp.Project/ Project Directory /version.<original>/ Version Directory /MyView.Class/ Class Package /MyOtherClass.Class/ Class Package /MyApp.nib User Interface /Other Sources Wraps, etc. /version.<current> Version directory. Items in here supersede those in /version<original> /MyApp.nib Later ideas for UI. -- NewsGrazer, a NeXTstep(tm) news reader, posting -- M>UQR=&8P7&%N<VE[7&9O;G1T8FQ<9C!<9FUO9&5R;B!/:&QF<SM<9C%<9FUO

Any help would be appreciated. Glen gpopick@fnbc.com

I have a paletized object that changed it's superclass and now the NIB file will not open. Using GDB on IB I found that it was not even getting to my read: method. If this is incorrect please let me know. The implications of this to paletized objects is significant. It makes me wish NIB files were structured ascii files so I caould edit one to correct this kind of problem. I do not like having a NIB refuse to load. -- Michael Allen Latta Kripalu Center harit@kripalu.com (413)448-3288
From: riedel@cs.ubc.ca (Marko Riedel) Newsgroups: comp.sys.next.programmer Subject: Nasty surprise. (DPS) Date: 2 Jul 1993 01:55:27 GMT Organization: Computer Science, University of B.C., Vancouver, B.C., Canada Distribution: world Message-ID: <2104if$81r@cs.ubc.ca> Keywords: DPS, stackoverflow I'm currently writing some code that relies quite heavily on pswraps for drawing. The program stores data in PS arrays between drawSelf invocations. It works fine, until I give it some truly monstrous image to chew on. (These aren't bitmaps, by the way. They're drawings of scheme environments, pairs, closures and the like.) I get the following error. DPS client library error: PostScript program error, DPSContext be128 %%[ Error: stackoverflow; OffendingCommand: 1 ]%% Seems pretty clear what the problem is, but how do I fix it? (I've already had a "dictoverflow" which I fixed with begin & end & a dict 384 entries long.) Thanks.

If you are a beginner (like me) and just want to get some example c++ programs running you don't actually have to go through those installations. NS 3.1's compiler is based on gcc-2.2.2 which has c++ support and assumes that files with a .cc extension are c++ code. You didn't get any c++ libraries with NS 3.1, but for starters, you can use the standard C libraries. For example, to use the standard C string library, you write: extern "C" { #include <string.h> }. Once you get much beyond helloWorld.cc, you'll want c++ libraries, and the author of the referenced post explained to me why you'll want to perform the installations described in his post. He said: >The logical choice [for c++ libraries] is of course >libg++. The problem is that the latest relase >will not compile under gcc-2.2.2, so if you want that, you will need >to get a newer gcc as well.

And >gdb, in contrast to gcc, is very difficult to port. The last two sentences are the reason why it is much easier to get going on c++ now that you have NS 3.1. It is the update of gdb more than the update of gcc that we have been waiting for. For those Objective-C programmers that haven't even looked at a c++ book yet but are thinking of doing so, may I recommend that the way to read the standard book (Stroustrup, 2nd edition, reprinted with corrections, February, 1993) is: (1) Read just enough of Chapter 1 that you understand cin, cout, << and >> because these objects and operators are used in the examples (chapter 1 was otherwise useless to me, and a considerable barrier to getting on with the book). (2) Skip to section 2.3.10 on "references" (a huge violation of C's principle of pass-by value). (3) Then skip to 3.2.6 on the "free store" (this facility helps do what the alloc: and free: methods do in Objective-C). (4) Then skip to section 4.4 which explains the extern "C" syntax noted above. (5) Finally, dive in to chapter 5, which is where the book really begins. Once you've read chapter 5, and particularly the paragraphs at the end of section 5.3.1, you'll be hoping more than ever that Objective-C survives. --Brian Hill

That is, gcc-2.4.5 probably doesn't contain NeXT's current implementation of Objective-C, so in any given module, I either don't get NeXT Objective-C or I don't get the latest and best version of gnu's C++ compiler and libraries.

I have never used Visual Basic, so I don't know how it "blows the socks" of NeXT Interface Builder and AppKit. VB tightly binds code to GUI elements. You literally are able to drag out visual iterative tools (buttons, directory browsers, etc), click on them, and code the click 'method'. This gives you the freedom to re-arrange placement, but not GUI expression (i.e. associate a certain control with a slider vs. buttons). IB allows a greater degree of separation between interface and code. VB is very strong in making everything accessible in one environment. IB/PB/Edit/GDB interact fairly well through NEXTSTEP, but are not as well integrated. You must always include VB's DLLs with your app that are appropriate, although these can be shared between different applications. Same is true for any custom controls used; additional *.VBX files. NeXT shared libs come with each machine, and bundles go a long way in cleaning up excess clutter over Windows. VB 3.0 allows quick and easy support for Object-Linking and DB Access. I suppose the db access is moderately comparable to DBKit (I believe they can handle SQL back-ends). Although NeXT Object-Linking is a snap compared to OLE, VB makes it easier to implement than NeXT. Perhaps the integration level is more akin to NeXT's Services ability. Pour moi?

Ok -- first of all, I'm just a novice C programmer -- I don't understand the actual code being used here, but I can still look it up and compare it to what I think it _should_ look like -- which is what I did... Now, most programs that I've encountered and attempted to compile on the NeXT (that weren't explicitly written for the NeXT, of course), seem to assume that execv is defined something like this: execv(name, argv) char *name, *argv[]; Now -- this is how the man page for execv says it is supposed to be defined and should therefore work fine that way. However, whenever I try to compile such code, GCC gives incompatible pointer type warnings... So, today I got sick of it and tried to locate it in the /usr/include libraries -- there, I found "libc.h" -- which is included by the program I was working on. Libc.h defines execv in this way: execv(const char *, const char **); Now, again -- I'm not familar enough with pointers to work it out myself, but I assume that there is the problem -- there seems to be a definite pointer compatibility problem there. (I also assume this is a common problem, but did not see a FAQ available... sorry if it's in there, if so just tell me to RTFfaq.) So -- is there a way to remedy this? Is that the source of my conflicting pointer problems? Why does the man pages say that it is the "standard?" way while it is actually not that way in libc.h? These questions and more will be answered on this episode of... SOAP! (wait, wrong reality...) - John...

I'm sure it's all documented, but I haven't had time to read the on-line docs yet :-). It all seems to have something to do with POSIX..... Anyway, I've been trying to recompile various things under 3.1, and run into a number of problems. gcc-2.4.5 built without problems, but I can't get libg++-2.4 to build: it chokes on procbuf.C, and even using the hint posted the other day by Magnus Nordborg, I can't get it to compile that. In trying to rebuild zsh, on which I depend heavily, I found first that in version 2.3.1, which built without a whimper under 3.0, the definition of DIR wasn't getting included. I fixed that by adding a conditionalized include of <sys/.dir.h>, and got everything to compile, but the loader complained about symbols it had been able to resolve under 3.0: ld: Undefined symbols: _setpgid _waitpid _cfgetospeed _tcgetattr _tcsetattr _tcsetpgrp _tcgetpgrp *** Exit 1 Stop. When I tried to build zsh2.4 (beta), I could compile everything (again, after getting it to include <sys/dir.h>), but the loader couldn't resolve a set of symbols much like those it choked on for 2.3.1, except that _strdup was missing instead of _waitpid. Using HeaderViewer.app, I can see that at least some of this stuff is around somewhere, but probably not all of it (e.g., strdup() still seems to be absent, a problem I've encountered with a lot of software - though in 2.3.1, zsh dealt with that problem itself).

POSIX will be supported in a future release. Of course, POSIX compliance isn't necessarily an all or none prop. I would guess that nearly all of POSIX is in fact part of NeXTstep. If you need POSIX Compliance on paper, than NS is not compliant. If all you need is to be able to write POSIX compliant apps on both a NeXT and some other box, then with some care and a little luck, you should have not problem. Luck comes in where your required feature set is concerned. If you need some feature from POSIX that NS does not contain, then you are out of luck.

Date: 2 Jul 1993 20:09:14 GMT Organization: California Institute of Technology, Pasadena Message-ID: <2124laINNg0q@gap.caltech.edu> Keywords: scrolling, Text Object To reduce the situation to its bare essentials: I have an RTFD Text object. I want the text's width limited to the size of the window (i.e. setHorizResizable:NO) I have graphics that are potentially wider than the window Q: How do I enable the horizontal scroller properly? Explanation: In Edit, there's no accomodation for this: you just have to resize the window (and therefore, the text). Here, I want the text to stay within the borders of the window (oppose: the RTF inspector in Workspace), but enable the scrollers iff there's a large picture. sizeToFit, though, just resizes the Text object to the bounding box of the _text_, it seems, ignoring the size of embedded graphics... so the scroller can't display anything that's already being clipped. What, if anything, can I do about this? 1) setHorizResizable:YES. Now, it seems to work, but that introduces a new bug: A user opens a new document, starts typing, and the sentence just keeps on going off to the right: it continuously resizes rather than wrapping. After hitting the first return, a size limit is set, and further typing will wrap appropriately. Am I misunderstanding something? 2) reset maxSize. Well, the graphics are potentially as large as full-screen size, so is that a potential bound? We can setHorizResizable:NO and get rid of 1), but now the horiz scroller doesn't adjust its elevator automatically. 3) forget it, and use the Edit solution. Is that fair to the user, esp if one of the targets is 640x480 portables? Thanks for your time. Ideally, someone out in net.land has dealt with this before, and knows a one-line solution to making the Text object take the size of its member NXGraphicCells into account.

NeXT mentions this in the 3.1 release notes. This is unacceptable for those of us who are trying to deliver a product and need the bug fixes. Our customers will be running against a current Sybase server so will need the 3.1 adaptor with its later Sybase library, but we need the 3.1 adaptor linked against the 4.0 DBLib library so we don't all have to go buy an expensive HP server for our development testing (yes, we will eventually buy or lease one for final product testing, but we can't afford to have one at each of our development sites.) I haven't asked NeXT to provide this "mixed" adaptor and I really don't know whom to ask, so if enough of you are in the same boat, maybe we can get NeXT to help us. And apparently isql and who knows what other executables also are linked against the new DBLib.

It's because any given read/write method first (un)archives it's super, then it's own data. Adding a new item to the R/W methods will also cause this to happen unless you set the class version and then use the version number to properly read back older archives. Depending on how much your class heirarchy changed, you may be able to play games enough to make it work. But if you've done more than remove class B from a C:B:A heirarchy, you are probably beat. One workaround is to open the nib file with the older palette, delete the offending object, save and exit. Then start IB with the newer palette and readd the new object.

Okay, a lot about handling the source code could be improved, but my main concern right now is: TURN-AROUND-TIMES Consider what happens when you press the Build button in Project Builder: - A shell is started, loading 122880 bytes from disk (/bin/sh). - Make is started, loading 49152 bytes from disk (/bin/sh). - Make loads 'Makefile.preamble', 'Makefile.postamble' and 'Makefile' which loads 'app.make' which loads 'common.make' - Now make begins to check the i-nodes of my 38 source files (yes it's a small project) for their modification time - Finally 'make' decides to recompile a source file, loads cc from disk, which loads tons of small header files (or a huge precompiled header) file - guess where from - yes, from disk. - Another source file has to be compiled. Again 'cc' is loaded from disk, again my 360 kByte precomplied header file is read from disk. - Lucky us, no more source files to be compiled, 106496 kByte big ld starts, reading 38 files of 60 kBytes each. You misspelled a variable name? Too bad, all over again ... Give me a break: handling only parts of my 160 kBytes of source code, producing a (stripped) executable of 180 kBytes my disk sounds as if it would soon collapse. And that after paying for 24 mBytes of RAM... Unix, especially Mach has strong interprocess communication features. Why not map my source code from Edit.app's address space to the always running compiler server, which already knows most of my header files, because this is the 27.th compilation it does for me today. I want to test the new code, click on gdb, and start the new executable that just arrived from the Linker Server without delay. Science fiction? No, have a look at your Services menu.

I agree, it does sound like a cacheing problem, but the odd thing is that I can view the file from the command line. This would appear to rule out file cache problems. (BTW, I'm not using NFS). It's almost as if the compiler itself is trying to do something clever. The last time it happened, I opened the file in vi then wrote it back - didn't help; saved it in Edit after getting the "someone has modified it" alert panel, and then the compiler recognized it again. So what does the compiler do that's different from "cat" and "vi"? Maybe it uses memory mapping rather than read? Dave Griffiths

To create a variable that can be shared by all instances of ClassA and no other objects, simply declare a static variable in your ClassA.m file and no where else (in particular, not in your ClassA.h file). Then all ClassA instance methods can access the variable, and even ClassA class methods (e.g, +initialize) can access it. Here's an example: ClassA.h: ... // There is no mention of the class variable "count" ... ClassA.m: ... static int count; ... +initialize { count = 0; } ... -whateverMethod { ... count ... }

Second, add the library in ProjectBuilder. Lastly, if you aren't placing the library in /usr/lib or /usr/local/lib, you're going to have to add the directory where the library is to the places that are searched.

The problem comes if you expect each subclass to inherit its own private copy of the "class variable." They does not. Instead there is a single copy of the variable shared by the class and all subclasses. Further, the subclasses do not have (direct) access to the "class variable." So if you are thinking this way you will be disappointed. To use this technique with subclassing, you'll have to redeclare your "class variables" in each subclass (Yuck!). Even then your code dealing with class variables won't inherit properly.... Joseph

This is correct, but let me just add my usual complaint about this approach and once again beg NeXT and/or FSF to consider enhancing the next release of Objective-C: These are not true class variables, because subclasses of ClassA will not automatically get their own copy. If you want subclasses to have the same functionality, without corrupting the values in ClassA, you need to redeclare them in the subclass's .m file.

The general idea is that the program will handle a large number of data points, data structures, etc... Each of these objects can have an inspector, which it knows about. Therefor, I would like to be able to query one of my objects for its inspectorView, and then insert it into my inspector. I want the code and the views for the inspectors to be independent of the application itself, and that is what is giving me headaches. I know that there is a way to do this using bundles. Unfortunately, I have never used the things before, and I am on somewhat unsteady ground when discussing them, let alone programming with them. So let me attempt to run an idea by, and if you could critique/fix/applaud/ etc... it, I would be most appreciative. (My e-mail address is different than my posting address.. sorry. Here it is: DAY@SATURN.AOML.ERL.GOV Thanks. My idea: Create a seperate bundle for each of my data objects. An example (and something that I am trying to do now), would be called WindObSet. In my appDidInit: method, I would load each of the apropriate bundles. This should load my class definitions for my WindObSet objects. (Lets rename the bundle to WindObSetBundle). I would then load the nib section containing my inspector views, etc... Now, can I control when the class definitions are loaded? And can I set up defaults in the classes when I do load them. For example, could I do something like this: open the bundle (how exactly do you do this, anyway??) open the nib section and set owner to anOwner. load the class definitions make calls to the factory: [WindObSet setInspectorView:[anOwner inspView]]; From here on out, whenever the [[WindObSet alloc] init] call is made, the factory will create instances of the object with an internal pointer to the inspectorView loaded from the nib section. I think that this will work, but I am really on shaky ground as to how to implement.

Date: 1 Jul 1993 22:13:33 GMT Organization: U.S. Department of Commerce, NOAA/AOML Message-ID: <20vnid$678@wave.aoml.erl.gov> Hi, a follow up to my previous post: I have a very complicated data structure that contains about twenty different types of objects. Furthermore, the ability to add new types of objects is an extreemly desirable thing. Needless to say, my class area is getting overrun with all of the class definitions, my nib file area is getting overrun with all of the.... well you get the picture. Each object has the following associated with it: The object class. An inspector controller class. An inspector owner class. An inspector nib file containing multiple views, etc... Right now, I have the thing working, but all my nibs, classes, etc... are in my working directory, and it is driving me nuts. One solution, obviously, is to just create a sub-directory for each of the object types, and keep the source code in there. BUT this doesn't lend itself to expandability, and it still won't fix my problem with overcrowded class and interface browser entries. I am sure that sub-projects are the way to go here. If I create a regular sub-project, are all of it's classes and nibs readily available to the PB compiling and linking session? If so, that takes care of my immediate problem, but I would still like to figure out how to dynamically load the class defintions. Any hints, suggestions, or examples would be appreciated. Thanks!

This solves most of the problems. The rest result from PB/ld bugs. As far as I can tell capital letters in the name do not work. PB buts in the ".a" in the name if capital letters are present. LD does not respond to names with the ".a" as documented. I would have liked PB to add the directory when it is not one of the standard ones.

Objective-C offers no way of making a method private, regardless of whether you include it in your .h file. At runtime, any method can be dispatched at the request of any other object (not necessarily even a subclass). It's enough to know the name and arguments, much of which can be learned through judicious use of AppInspector. NeXT puts an underscore in the front of private method names, to highlight their status and discourage you from calling them. That doesn't mean you can't use them if you really want to. However, you do so at your own risk, because private methods can go away, change arguments, etc. > However, I do get warning messages from the compiler: > > ClassName.m:92: warning: `ClassName' does not respond to `methodName:' > > Should I ignore these warnings, or is there another way to define > "private" methods in Objective-C?

I have a library "libDBKitExtensionsPalette.a", which is located inside my project's source-directory... So I just dragged it into ProjectBuilder's Libraries section and added a -L. to my Makefile.preamble 's OTHER_LDFLAGS. Of course, the library inside ProjectBuilder's Libraries' list appears as "DBKitExtensionsPalette", as it should.... And when compiling I see the -L. and -lDBKitExtensionsPalette flags as I would expect... It *would* help to use libDBFilter.a instead of DBFilter.a... Also, I've found it useful (but by no means essential) to use "ar q <obj-files>", as I have extremely long filenames that tend to collide and override each other... Of course, this kills updating portions of the library -- I have to rebuild it completely each time... But that's fairly fast... And, as long as we're on the subject, has anyone tried writing a libIB.a yet? Some sort of template-class definitions so we don't have to worry about filtering out all the IBInspector, etc classes from (IB) Palettes when we go to build libraries for those Palettes? Just a thought. -David. (Still Using NS3.0. *sigh*)

What is strange is 1) using the debugger, I can setPath: to another layered data path and have that selected just fine before exiting the data addition method 2) if I setPath:"/bogus/path" then setPath: to the correct path it works just fine!

Date: 6 Jul 1993 15:08:37 -0400 Organization: Express Access Online Communications, Greenbelt, MD USA Message-ID: <21cijl$64d@access.digex.net> I have an application which is mostly compute-oriented (COMPUTATION!) as opposed to user/interactive. In other words, instead of responding to user events, my program performs a number of computations inside a loop. This is how to works on traditional machines like Suns, Macs, etc. Well how to perform this periodic set of tasks on the NeXT? Somehow I have to have my subroutine calls initiated by NXApp. Should I subclass NXApp in some or perhaps have these tasks subclassed from a periodic tasking class (don't know what that would be on the NeXT)? Ideally I would like to have a "controller" which actually does the controlling as opposed to being driven by events.

Distribution: world Message-ID: <21cjm5INNlgk@frigate.doc.ic.ac.uk> Keywords: drivers frustration help 3.1 NS486 Originator: apl@santos.doc.ic.ac.uk I'm interested in writing a driver for my graphics card, an Orchid Fahrenheit 1280D, for nextstep/486. The trouble is, documentation on writing drivers is particularly lousy. I've even resorted to examining disassembled tseng4000 drivers (which came with the system)... If there is anyone out there who knows about the topic, I'd appreciate answers or pointers to answers to some of the following problems which have been vexing me: (a) which driver gets loaded by the system? Is it the one in /usr/Devices or the one with the .psdrv extension in another device driver directory? Or is it both? If both, how do they interact? Why does the boot process seem to try to load about 3 different video drivers? (b) I understand the cursor-related calls, and the console stuff. What I can't figure out is how a reference in the kernel windowing routines to some position in the frame buffer gets translated to a call to reference video memory. (c) Why do the tseng drivers register themselves with the event driver? (d) Where are globals such as kmId to be found? This seems to be used in the driver with Objective-C routines, but I can't find it in the include files. Nor can I find routines such as NXRegisterScreen, which are used in the .psdrv driver. (e) Most of all, I would like to know, is writing a video driver at all possible in this release. Or have I just been wasting my time. Any help on these topics would be greatly appreciated... even from anyone at NeXT. Thanks, Ari PS. I like my graphics card. You may have guessed. Seems however silly to pay 300 pounds for a new card when this one will still do. And yes, the 300 pounds would be from my pocket which motivates me a great deal..

However, you'll still be getting a pretty ugly window. It won't have all the pretty features of a normal window and you have no idea where on the screen it will be. A slightly better solution is the following: NXRect aRect; id window; NXSetRect(&aRect, 100.0, 100.0, 200.0, 300.0); // or whatever size you want window = [Window alloc]; [window initContent:&aRect style:NX_TITLEDSTYLE backing:NX_BUFFERED buttonMask:NX_CLOSEBUTTONMASK defer:NO]; [window setTitle:"Ack!"]; [window orderFront:nil]; ....

B = 0.3; [myBField setDoubleValue:B]; [myBSlider setDoubleValue:B]; return self; } Some notes: I use [NXApp currentEvent] rather than [NXApp getNextEvent:...] because there sometimes is no NextEvent to get, since the error can occur while the mouse is moving the slider, or at some other time. I run the alert panel immediately so the user knows there is a problem. I reset the parameters only after the mouse event has been taken care of so that the mouse event doesn't go to the slider and change its value. I make sure the event is out of the way before proceeding by using the method perform:with:afterDelay:... with a delay of 0. I still find the solution quite ugly, but it seems to work.

Date: Tue, 6 Jul 1993 18:55:02 GMT As a follow-up to a previous post, DBKit appears to be incapable of dealing with fields type Sybase "text" - this is using the adaptor that comes with NS3.1 (Intel) and a Sun-based SQL Server 4.9. The version of isql that comes with NS3.1 works fine (i.e., it can retrieve text fields with >100 characters in them) which probably means that the problem is in the Sybase adaptor.

We have a largish project, with lots of header files that #import other header files, including some that #import each other. We have had no problem with this until now. We have something like this. wibble.m #import "wibble.h" @implementation wibble @end wibble.h #import "wingle.h" #import "wungle.h" @interface wibble:Object { id fred; } @end wungle.h #import "wibble.h" #import "wingle.h" @interface wungle:Object { wibble *banana; } @end wingle.h #import "wungle.h" @interface wingle:Object { id SomeStuff; } @end Confused? Just wait.... The real situation is pretty complex, but this gives the gist of it. The odd thing is that when we compile say, wibble.m, we would expect that the class 'wibble' would be defined by the time the definition of banana is reached in wingle.h. Sure we are recursively #import'ing, but I would have thought that the first #import happens, sets a flag and then doesn't try to import again so the recursion stops. Unfortunately this isn't the case. It appears that the pre-processor doesn't immediately send to imported (or #inclued either) file to the output, it seems to output them in a strange order, it looks like it puts them onto a stack, then works out that they are recursive, then unwinds the stack. The result of preprocessing is seen below ( cc -E wibble.m ). Even though wibble.h is the first imported file, it is actually imported last, result is a complaint that wibble is undefined in wungle.h # 1 "wibble.m" # 1 "wibble.h" 1 # 1 "wingle.h" 1 # 1 "wungle.h" 1 @interface wungle:Object { wibble *banana; } @end # 1 "wingle.h" 2 @interface wingle:Object { List *SomeStuff; } @end # 1 "wibble.h" 2 @interface wibble:Object { id fred; } @end # 1 "wibble.m" 2 @implementation wibble @end Whew!

In our project we subclass DBTableView and at runtime replace all references to that class with the subclass using a poseAs: [[myTableView class] poseAs:[DBTableView class]] This way we are able to do the IB linking as usual using ordinary DBTableViews and still get all the functionality of the subclass.

I just finished reading a short article in Open Systems Today (July 5, 1993) announcing Microsoft's intent to use Visual BASIC as the basis for their application macro/scripting language. Nothing TERRIBLY new here, MS has had a love affair with BASIC for some time. The thing that jumped out at me was how MS is putting together the pieces (Windows/Windows NT, OLE, Visual BASIC, Visual C++, etc.) to enable (read that as EMPOWER) end-users/power-users to be able to integrate/customize/organize/objectize their environment to suit their needs and to solve their problems! While we can argue 'til the end of time about how slick Microsoft's implementation is, and whether they have a system that is truly object-oriented in the classical sense (polymorphism, encapsulation, abstraction, and on, and on). The REAL point is (isn't it) that they are attempting to develop the infrastructure to EMPOWER people and organizations to solve problems. What I'd like to know, is why, on the NEXTSTEP platform (object-oriented as it may or may not be) haven't we broached this subject with more force? Certainly Athena Design w/Mesa deserve credit for providing a number of ways to use Mesa (MScript, MOLI, etc.) But where are the others? Glenn (Reid), if you're there, is PasteUp (and will) ExactlyWrite be as open and as easy to customize as Mesa? What about Pages (Bruce Webster might be able to answer this.)? Appsoft (are you still in business?) what about Image, Draw, Write, Solution? What about Andrew (Stone) and Create, DataPhile, etc. What is everyone doing to take advantage of the smallness of the NeXT community in order to provide the same (or hopefully, 10-times better) capability that Microsoft is attempting? We should all be looking to the young OPN (Open Protocols fro NEXTSTEP) organization, as an independent effort to coordinate such activities and discussions. Furthermore, while object-oriented design & programming in the Objective-C/C++/Smalltalk/etc. sense of things is exciting, profound and has terrific implications for developers, we MUST be thinking about "Application-level Object-orientation". That is, enabling users (power or otherwise) to think of applications as objects. Or perhaps, the application is not the right model, but something in between a sub-class of Object and a 6000-feature application. Let's get this thing going! (to quote a line from one of my daughter's "Sing-Along" videos), "Let's get together...ooohoooo". Let's take advantage of the smallness of the NeXT community to create (hopefully) some bigness, before Microsoft takes advantage of their bigness and everyone else (especially us) is relegated to smallness! --- Chris Cuilla ITSolutions, Inc. --------------------------------------------------------------------- NeXTMail: chris@its.com Phone: 312.587.2000 --------------------------------------------------------------------- My opinions are...(who cares!) --------------------------------------------------------------------- "There's no such thing as a 'part-time perfectionist'." ---------------------------------------------------------------------

The problem is that the linker by default only links in symbols that are present in your application from your libraries (this is usually good). With dynamic loading or with calls like objc_lookUpClass("MyClass") it is possible to need symbols that were not statically linked into the application.

The problem is simple enough: I want to parse "foo-3.5" as the binary expression "foo - 3.5". But the -3.5 is captured by my lexer as a negative constant, and my parser dies 'cause a symbol followed by a numeric constant is not a valid expression. I don't want to force the user to use spaces in this case. If anyone could point me to an answer, that would be great.

If you have a method in the '.m' file, it will be just as accessable as any other method. By not declaring the method in the '.h' file, you will get the compiler warning you mention, but this has no effect on the "invoke-ability" of the method-- it's just another instance method, and works exactly like all the other instance methods (try it if you don't believe me!). This means that there is no such thing as "private" methods in Objective-C. I tried the same thing you tried to achieve "private" methods, but I didn't like the result since any user of the class is instantly informed (by the compiler) of the existence of the "private" method, and they can still invoke those methods anyway if they choose. My final solution was to explicitly extend the class via a <private> category, and have the interface information for the <private> category contained in the ".m" file. This solution explicitly marks the methods as private (useful for future maintence of the class), without revealing the existence of the "private" methods in the '.h' file for the class, and without the compiler revealing their existence either. However, even this is still just an approximation, since if anybody does decide to send one of the "private" messages (or, I should say, a message that invokes a "private" method) to an instance of the class, it will still be executed just as any other method would be. Another alternative might be to use a <private> category, but go ahead and put the interface information for the <private> category in the '.h' file, thus documenting to the world that these are "private" methods, and trusting that users of the class will respect the "private-ness" of the methods and not directly invoke them.

One way to solve this is to have the lexer not recognize negative constants and let -3.5 be parsed as a unary minus operation. If you're worried about effiency, you can have the parser recognize the special case of unary minus applied to a constant and replace it with a negative constant. Tony

Date: 8 Jul 1993 01:37:53 GMT Organization: Massachusetts Institute of Technology Distribution: world Message-ID: <21ftph$8i9@senator-bedfellow.MIT.EDU> I am trying to program something for my research, and being a semi-novice programmer, I am boggled by the following: I have a separate nib file to handle setting preferences. I want values from a form object to be input into a EquationController class. Therefore, I instantiated an EquationController object in the preferences nib, and I am having the form object send its values directly to the EquationController via a setConstants:sender method. This seems to work, and I am able to set various constants (which are instance variables in EquationController). HOWEVER, these values DO NOT STAY SET! When the setConstants:sender method ends, the values that were set (confirmed by using gdb) are not "stored"permanently. These values (instance variables in EquationController) only stay "set" WHILE the setConstants:sender method is in use. After it finishes, the old constant values (i.e. before setConstants:sender was called) get set. 1. Shouldn't instance variables for a class STAY SET to a certain value once they are changed??? Why in this case do the variables change only temporarily? 2. Another question I had was, what happens if you instantiate a class object in two or more nibs? I instantiated the EquationController class in the preferences nib and the main controller nib. If I make a connection in one of the nibs, will the class know about the connection even if it doesn't show up in the other nib? Thanks, Eric

NeXT mentions this in the 3.1 release notes. I have received private correspondence from NeXT indicating that my interpretation of the 3.1 release notes was not what NeXT intended. NeXT intended to warn against using new Sybase 4.6 features against a Sybase 4.0 database and states that the 3.1 Sybase adaptor is backward-compatible with Sybase 4.0 database servers. So NeXT has not begun dropping support for black hardware as it appeared. Therefore, the problems we have experienced should be considered bugs, not lack of support. However, the bottom line remains: the 3.1 Sybase adaptor cannot be reliably used with Sybase 4.0 database servers in our experience. Try these simple tests to determine whether you will have the same problems as we have seen: - Insert a new record with a duplicate key into a table on which a unique index exists on the key. After Sybase reports a "duplicate key" error, try to refetch data. Our experience is that the client app will then hang and must be killed. - Insert more than 256 characters into a Sybase text datatype data column. Repeatedly fetch this data. The client app should crash either on the save or on one of the subsequent fetches. The crash can occur immediately, or it may take several repeated fetches, but our experience indicates that crashing will eventually occur thus making the client app pretty unusable. - We have seen the following occur at 2 sites on 2 different occasions, but have not been able to reliably reproduce it. Run the 3.1 isql or possibly any other app linked against the Sybase 4.6 client libraries against a Sybase 4.0 database server. Concurrently, run a DBKit client app using the 3.1 Sybase adaptor against the same server. As long as another 4.6 app is running, data cannot be fetched using the DBKit app. As I indicated, I don't know the exact sequence of events or circumstances that leads to this problem, but if you suddenly cannot fetch data using your DBKit app, check whether any other 4.6 apps are accessing the server. We have produced a simple NEXTSTEP app (and sent it to NeXT) that demonstrates the first 2 bugs. By merely rerunning the same app using the 3.0 Sybase adaptor, the problems disappear. NeXT claims to have had only one other complaint about this apparent incompatibility between the 3.1 Sybase adaptor and the 4.0 Sybase server. If you experience similar problems (or any problems that you suspect result from this incompatibility), please report it to bug_next@next.com using BugNeXT.app so that NeXT can come up with a fix ASAP. -- Art Isbell Cubic Solutions NeXT Registered Developer NEXTSTEP software development and consulting NeXTmail: isbell@cats.UCSC.EDU Voice: (408)335-1154 USmail: 95018-9442 Fax: (408)335-2515

He could also add instance variables in a clever manner that was mentioned on the net not too long ago. 2) He could create a new class that archives in the same manner as the Window class, and have his own class 'poseAs' the Window class. His class still needs to be a subclass of Window, but there are a few less limitations with poseAs than with categories. 3) Write his own! There's no reason that I can think of that he couldn't write his own Window class. Now THAT would be fun! Ken Anderson anderson@biztech.com Stamford, CT

References: <21ftph$8i9@senator-bedfellow.MIT.EDU> Date: Thu, 8 Jul 1993 15:34:52 GMT Eric, From what I can gather from your message (not copied because of size), I would bet that you're reloading the nib file everytime you bring up preferences. I could be TOTALLY off on this one, but it's the only explanation I can think of for the behavior you're seeing. Basically, when you instantiate an object in a nib file, it's already instantiated, and gets freeze-dried into the nib file. When you load the nib, that instantiation becomes live again...the way the instance variables were set inside IB. Of course, if the object was the SAME instance that you sent the setConstants: messages to, the variables should definitely stick. When you check the variables afterwards, check to see that the address if the object is still the same. You must realize that your preference settings won't be carried in the object from one execution to another. To accomplish this, you should probably use the defaults database. Search on NXDefaultsVector to get an idea of how to use this. If you're still stuck, send me mail. Good luck! Ken Anderson anderson@biztech.com Stamford, CT

When you load the .nib file for the preferences (with LoadNibSection), have the owner: parameter passed in as the EquationController you instantiated in the other .nib (usually by having the prefs button send a message to the EquationController object - set this up in interface Builder - and have that method do the LoadNibSection). -- >>> Gordie Freedman -> gordie@cyclesoft.com NeXTMail Yes! >>> Thou shalt not inline functions more complicated than 20

With the function NXBeginTimer(), you instruct your program to add an event at any given interval. That technique is used when you want to track a certain condition during a loop. When you take care of a "MouseDown" event, you could start a stream of timed event to check if something has changed during the time the user keep the mouse down. You stop the stream with you get a "mouseUp" event. 2) You can use DPSAddTimedEntry() to instruct your program to call a C function at any interval. You can have many timed entries active at the same time. If you want to make call to an object from within the timed function, you must provide such an object with the userData parameter of the function. 3) In the object additions, there is a very nice method named - perform:with:afterDelay:cancelPrevious: A method can call itself using the following technique: - myMethod:sender { [self perform:@selector(myMethod:) with:sender afterDelay:1000 //in miliseconds cancelPrevious:YES]; /* ... other stuff here! */ return self; } To intitiate the stream, just call "myMethod:" from -appDidInit: or -awakeFromNib.

I'm looking for feedback on the kit, so let me know what you think and I'll try to turn it into a professional (and inexpensive) kit. WARNING: The 0.1 version has been uploaded as a Multi-Architecture library, but has only been tested on black hardware under 3.1. It should work fine on the NS/fip 3.1, but the library is unusable under 3.0.

This is necessary because ProjectBuilder can't handle Application subclasses defined in subdirectories properly. --- The ThreadKit consists of three classes: ThreadedApplication The core of the kit, it adds mechanisms necessary to allow threads to access non-thread safe (eg: AppKit user interface) objects with impunity. Any thread that needs to access an object that wasn't originally designed with thread-safety in mind can do so by locking the entire appkit thread through the "lockAppKit" method. When done with processing, the thread can be unlocked via the "unlockAppKit" method. It also asks the objective-C runtime mechanism to become thread-safe on your behalf. ThreadedMessage A mechanism for spawning autonomous threads, sending an "initFor:performing:" message to a newly created ThreadedMessage spawns another thread and sends the specified message to the specified object. Note: Once the ThreadedMessage object is activated via this message it should be left alone. It will free itself when the message is complete, and sending it further requests in the interim will have unpredictable results. Anytime a new thread is desired, just create a new instance. ThreadedObject A subclass of object that provides an inherent locking mechanism. Sending the "lock" and "unlock" messages surrounding any atomic actions performed on the object will keep things rolling smoothly... --- This version of the ThreadKit is a very early step in trying to make multithreaded NeXTSTEP programming a little less arcane. It is intended to be released as a commercial product at a very reasonable price when complete. This early version expires July 22. The simple example included demonstrates use of two of the three classes, more examples will be forthcoming... Feel free to write with comments, suggestions, criticisms. Whatever.

The 3.1PR1 kernel did ttys in the same fashion as 3.0, 2.2, 2.1, etc., at least on Motorola platforms. It's anyone's guess what's different on Intel platforms. NeXT has actively discouraged the ability to write user-loadable line disciplines. In 3.0, for example, header files which used to document installing line discipline just disappeared. It may be that some interfaces have changed on the Intel box. On the other hand, you just be seeing the broken serial driver bug, manifested in a different way. It may be pointless to continue until that issue is resolved. It's pretty much a show-stopper for me. > Being in a kernel, it's a !@#$ to debug :-( You bet. In the network software that I'm working on and testing now, I do all the interesting stuff in user code, with an absolute minimum amount of code in the kernel.

I had to mess around with the make file a bit, but finally got a clean build. The problem is that some (but not all) of our scripts work fine on black gear but fail on the white. Here's the scoop: We built a fat perl which passes all the regression tests. We built a fat uperl.a (not the uperl.o the sybperl makefile wants). We used libtool against the perl *.o files that uperl.o depends on in the perl makefile. We then linked sybperl.o with this archive file to create the sybperl executable. When we run sbex.pl (the sybperl test strap) on the black hardware it runs fine. On the white hardware we get: $dbproc parameter is NULL or the connection to the server has been closed. at sbex.pl line 34 This is the first call to dbnextrow in the test strap. Running in the debugger shows a valid return from dblogin and sp_who from isql shows we have a good connection prior to this call. We can execute dbnextrow interactively in the debugger, and other scripts are successful with it. As far as I can tell, sbex.pl differs mainly in that a call to dbopen is used to generate second dbprocess. Our one other script that does this (a hacked version of sbex.pl) also fails on it's first call to dbnextrow. Running interactively in the debugger on the white hardware we can call dbopen add nauseum without problem. setenv in the shells executing the scripts shows the same values for DSQUERY,DSLISTEN,and SYBASE on both black and white gear.

(PR) Message-ID: <1993Jul9.212637.2550@dolphin.com> Sender: zac@dolphin.com Organization: Dolphin Software Distribution: usa Date: Fri, 9 Jul 1993 21:26:37 GMT Press Release Dolphin Technologies Inc. Announces Dolphin Kit Object Library Contact: Zacharias J. Beckman Dolphin Technologies Inc. 10329 Viretta Lane Beverly Glen, CA 90077 July 1, 1993--Dolphin Technologies Inc. announced the availability of the Dolphin Kit NeXTSTEP compatible class library, version 3.1, for NeXTSTEP (available for both Intel and Motorola hardware). The kit is a set of classes which run in the NeXTSTEP environment and focus on common functionality that many applications require. The classes expand upon the existing NeXTSTEP API and deliver new objects not formerly available. The Dolphin Kit provides a comprehensive set of tools, classes, and protocols for building applications that use a high-level object oriented approach to many common needs in application development. The kit provides services that include: Simple string and "sentence" storage and manipulation. Encapsulated use of Mach files and devices (i.e.: flat files). Management of C Threads and multitasking. Extensions to several standard NeXTSTEP API classes. New container classes. Facilities for generating NeXTMAIL. Part of the functionality of the Dolphin Kit is a set of tools for building more robust applications. Most applications make use of memory to store strings or other blocks of data. Dolphin's String class can be used to greatly simplify direct use of memory. For example, calls to memory allocation and free functions are encapsulated. By encapsulating the use of memory in a robust library, many problems in the area of memory management and memory overrun are prevented. The Dolphin Kit helps by providing: Several String classes for containment of a block of memory (typically used to store terminated character strings, read only strings, and an ErrorString class to encapsulate error handling). A Parser to provide greater flexibility in manipulation of character strings. This makes it possible to manipulate such strings without danger of memory overruns and other miscalculations. Classes for the encapsulation of Mach file and device manipulation and use of multiprocessing via C Threads. Tight integration between the File, Process and String class make an excellent tool for execution and reporting on Mach command line operations. A NodeTree for storage and manipulation of data which can be stored in a tree. Subclasses of List for sorted storage and delegate notification in the event of changes to the container contents. A simple but very handy encapsulation of memory allocation using NXZone's. The Memory class makes using zones and blocks of memory a little bit less tedious and much more reliable. An interface to creating authentic NeXTMAIL, including attachments and rich text, via Mailer. C++ wraps around those Dolphin Kit classes that benefit most from C++ features. The Dolphin Kit version 3.1 will be available July 30, 1993, for a purchase price of $249.00 US. For detailed information on the kit, send electronic mail to <info@dolphin.com> or contact Dolphin Technologies Inc. at 10329 Viretta Lane, Beverly Glen, CA 90077. Facsimile can be sent to 310-441-9041 and voice calls are accepted at 800-843-0328. -- END -- -- Zacharias J. Beckman - Dolphin Technologies Inc. - zac@dolphin.com - NeXTMAIL!

WARNING: I am not claiming this technique is pretty or that it is an acceptable substitute for real class variables. That said, you can simulate a real class variable (but only if all access goes through a set of class methods). The technique is to declare a HashTable instead of the variable you want. The key for the has table will be the class name. The value will be the value of your "classs variable" for that class name. You must then write +classVariable and +setClassVariable methods which manage the HashTable properly. In this way, you can encapsulate the class variable where it belongs and avoid the problem with subclasses. Like I said, it's not pretty. But you'll only have to write the code once. ____________________________________________________________ Mike Ferris mike@lorax.com (Fnord) Rubicon Software (510) 652-2039

Sorry to interrupt, but I was told, some time ago, that if you didn't have "nocompress" in your swap.tab, you'd get the "swapfile.front" file, wich is a compressed version of swapfile, and thus replaces swapfile. Therefore, in the situation above, "swapfile.front" is actually the working swapfile, while swapfile is "just some virtual thing". Please, do correct me if I'm wrong. Confused.

I have a ZyXEL U1496E and NXFax, and wondered about a few things. NXFax currently does not support Caller ID function of the ZyXEL, but I would like to register which numbers have called my modem. The standard NXFax log gives only information for calls which are successful (i.e. it gets the fax number of the calling machine from the remote machine). I don't have an answering machine (I have am, but too bad it doesn't work with NXFax :-( but registering the Caller ID would be almost as useful for me. Additionally, I suspect (my paranoia :-) someone has been calling the machine trying to log in... I know, I could just turn off data calls, but I use it, and I would like to catch this individual, if it is really happening. Below is the `standard' NXFax log. How hard would it be to write a script or daemon that went to the modem and got the caller ID info after such an entry was logged, and logged it in a file? For a non-programmer... I know the modem command AT*T returns the last Caller ID. Could a small script watch over the ZyXEL log, and upon seeing the `ring 3' string (maybe `call complete' would be more appropriate) wait some seconds, establish a connection with the modem, issue AT*T and save the resulting string into a file with a date/timestamp? Would it maybe be better to find some way to log the Caller ID info directly from the modem/program while NXFax is answering/looking for a remote fax? As a non-programmer, I assume that the above is certainly perhaps the most difficult way to accomplish what I want, so if anyone (who knows what they are talking about :-) has any suggestions or tips, I would welcome them.

The general consensus was that it is worthwhile (simple) to install the latest version of gcc (2.4.5). I used as my configure: configure i386-next and it "just worked." Most important, NeXT's latest version of gdb works with output files generated by 2.4.5. With gcc 2.4.5 installed, the latest incarnation of libg++ was installable. With the same configure, the installation worked---almost. There was one compile problem. Magnus Nordborg gave the nicest explanation of how to work around it, and it follows this message. Subsequent installation of other software (e.g., oleo) revealed some odd problems with the dir.h and dirent.h files, but nothing that was not solved by handcoded include statements. So, in general, I now seem to have the latest gnu compiler+libraries on my NS-FIP, even though I am everything but a gnu/compiler guru. Thanks, FSF. [Yet, I am wondering exactly what the newer release of gcc took from NeXT's header files. I believe the gnu installation does not touch anything in NeXT's directories, but sets up everything under /usr/local/lib (even the include files). So, if I ever need to try the original version, I just have to rename /usr/local to /usr/unlocal temporarily). Anybody know more about this?] /ivo welch

Date: Sun, 11 Jul 1993 21:23:40 GMT This is probably a really stupid question (at least I hope it is), but I haven't been able to find a solution. How can you set a serial port on NS/FIP for two stop bits (CSTOPB in POSIX/System 7)? There are POSIX calls to do it (tcsetattr), but there is no way to build a POSIX application in 3.1 (at least according to the release notes, and I can't find a library with this call - also, there doesn't seem to be a way to set stop bits in 3.1's expanded ioctl's). The device I'm talking to has no adjustments and requires 8 bits/two stop bits (so there's no faking it with 7 bits and a bogus 8th bit). I can't believe there wouldn't be a way to set this, but I can't find it. And I don't mind feeling really stupid when someone points out the obvious answer :-).

I just can't leave this puppy alone. After another weekend of tuning and extending, ThreadKit 0.5.tar.Z is now on cs.orst.edu and sonata.cc.purdue.edu in the /pub/next/submissions directory. If you've ever tried to do multithreaded programming on the NeXT, you know what a pain it can be. ThreadKit to the rescue! --- *** Preliminary ThreadKit Release Notes *** The ThreadKit consists of four classes and a category: * TKApplication The core of the kit, it adds mechanisms necessary to allow threads to access non-thread safe (eg: AppKit user interface) objects with impunity. Any thread that needs to access an object that wasn't originally designed with thread-safety in mind can do so by locking the entire appkit thread through the "threadLock" method. When done with processing, the thread can be unlocked via the "threadUnlock" method. * TKThread A mechanism for spawning autonomous threads, sending an "initFor:perform:" message to a newly created ThreadedMessage spawns another thread and sends the specified message to the specified object. * TKObject A subclass of Object that provides an inherent locking mechanism. Sending the "threadLock" and "threadUnlock" messages surrounding any atomic actions performed on the object will keep things rolling smoothly... * TKResource A subclass of TKObject that manages named resources * Object(ThreadLocking) A category of object that extends TKObject's locking semantics to all objects --- This version of the ThreadKit is an early step in trying to make multithreaded NeXTSTEP programming a little less arcane. It is intended to be released as a commercial product at a very reasonable price when complete. This early version expires July 31. Two simple examples included demonstrate ThreadKit use, more to come... --- If you haven't already unpacked the ThreadKit, do so now with the following commands, where <ParentDirectory> is the directory containing the ThreadKit-0.5.tar.Z file: 1. Type cd <ParentDirectory> 2. Type gnutar -xzf ThreadKit-0.5.tar.Z Now install the ThreadKit files into the appropriate places with these commands, where <ParentDirectory> is the directory containing the ThreadKit directory: 1. Log in as (or su to) root 2. Type cd <ParentDirectory>/ThreadKit 3. Type ./install This installs the actual ThreadKit files in /LocalDeveloper/Headers/threadkit, /LocalDeveloper/Libraries and /LocalDeveloper/Documentation/ThreadKit. Sybolic links are created from /LocalDeveloper/Headers (to overcome a limitation in ProjectBuilder) and /usr/local/lib (to allow the linker to find the kit). --- Planned future changes - Fewer API changes to existing classes (Apologies to early adopters) - Proper .pkg installation process - More examples - A mechanism for locking ALL threads to ensure integrity of REALLY dangerous actions (eg: dynamic linking of new classes) - Implementation of bright suggestions from the Internet community! Changes in 0.5: - WARNING: The size of the TKApplication and TKObject classes has changed, any subclasses need to be recompiled - WARNING: For consistency between the growing number of ThreadKit classes and a desire to avoid naming conflicts, all locking and unlocking methods have been renamed "threadLock" and "threadUnlock" respectively - WARNING: For consistency with AppKit methods, the TKThread method "initFor:performing:" has been renamed "initFor:perform:" - Trying to lock the appkit from the main thread is now harmless - Added locking semantics to ALL objects through the Object(ThreadLocking) category - Added named resource locking via the TKResource class - The "tryThreadLock" method has been added to all classes in order to attempt locking with non-blocking semantics Changes in 0.2: - Class names changed to shorten names and prefix all ThreadKit classes with "TK" - More robust error checking (now only the thread that locked the AppKit can unlock it!) - Threads are discarded properly when finished - Nested locking of TKApplication is now supported - Real documentation written & included - The Objective-C runtime is now made thread-safe only when more than one thread is running - Changes to the "SortingInAction" example code to use the ThreadKit are supplied. See ThreadKit/Samples/SortingInAction/README for details - Beta period extended to July 31 Changes in 0.11: - Now supplied in single-architecture as well as multi-architecture form for those running 3.0 --- Feel free to write with comments, suggestions, criticisms.

I have a NeXT 040 cube running os release 3.0. I have a zyxel modem. For those in other newsgroups, this runs a bsd 4.3 / mach 2.x combo. If there is a way to do this in bsd, then it should work here. Looking at the man pages and the ioctl header file (joy joy), I have found 3 suggestive calls: #define TIOCHPCL _IO('t',2) /* hang up on last close */ #define TIOCEXCL _IO('t',13) /* set exclusive use of tty */ #define TIOCNXCL _IO('t',14) /* reset exclusive use of tty */ So, there doesn't seem to be an opposing call to TIOCHPCL which would not hangup on last close. If I leave all 3 of these out of the open, then it hanges up when I close. If I put the exclusive use of tty in there it still hangs up. I think I have used as least one program on the next which didn't hang up after it died. Mail me or post and I will summerize. thanks, nick kline kline@cs.arizona.edu

My first stab at this involved setting up a timed entry which then called peekNextEvent. Basically, the following method gets called once per minute by a timed entry. If the peekNextEvent method returns NULL, we have waited for an event for the defined timeout period, so it's time to signal the appropriate handler via target/action. - doTimedEntry { NXEvent dummyEvent; if ([NXApp peekNextEvent:[self eventMask] into:&dummyEvent waitFor:[self timeout] threshold:NX_BASETHRESHOLD] == NULL) { // we timed out! [NXApp sendAction:[self action] to:[self target] from:self]; } return self; } This works - sort of. It does everything I need, but there are two problems. One, calling peekNeXTEvent chews a lot of CPU (evident using a CPU monitor such as TimeMon). The other problem is that the system changes over to the wait cursor while peekNextEvent is waiting. This can confuse users who have not used the app for more than a minute, but go to do something before the timeout period has finished. So, has anybody done this sort of thing? I have though of subclassing Application and over-riding getNeXTEvent, etc, but I can see ugliness down that path. The other possibility is setting up a separate thread to call peekNeXTEvent and signalling the main thread, but there are app-kit multi-thread issues here (or are there?) Anybody have any advice?

Note that your application is on hold and won't respond to user events until you are finished processing the timed entry. It works well for non-time critical code that doesn't take long to execute, but it doesn't solve the problem normally approached by multi-threaded applications. > Also, DPSAddFD is the same way. it seems to be threadsafe, in > that it's okay to call things from here which call the appkit. Watch out for your definition of "threadsafe". Yes, you can do things in your handling routine with the appkit... but again, they don't run concurrently with the rest of your application. If by calling it thread-safe, you mean that you would like to call DPSAddFD or DPSAddTimedEntry from within a thread... Watch out! The AppKit just plain isn't thread-safe! This will at worst be disasterous, and at best result in a file handling / timed entry that interrupts your MAIN thread between events, not the thread that called the routine. -- Blake W.

Sure, these all work as an alternative to threads. They are not separate threads, however. The true benefit of multiple threads is seen on a multi- processor system. On an MP, the threads can be run on different CPUs, thus improving the throughput of your code. The methods you suggest are much simpler and do not require locking because they are all in the same thread and therefore are synchronized by definition. But on an MP, by virtue of all being in the same thread, they won't allow for concurrency that might otherwise be exploited. Of course, until you can get NS for MP machines, this is a much simpler way to write your code. If you want to plan for the future, though, take the dive into threads... (Of course, I'd hope to see finer grained parallelism, too, sommeday...but threads are a reasonable tradeoff at this point for some applications.) I'm sure there's plenty more that could (and will) be said about this... Later, Don_Yacktman@byu.edu -- Don_Yacktman@byu.edu Nepotism is a relative thing.

It could be a LOT simpler than that. Do you need to quit after 10 minutes of no activity whatsoever or no activity in your application? The call "NXAutoDimTime" (See /NextLibrary/Documentation/NextDev/ ReleaseNotes/EventStatusDriver.rtf for details) allows you to "see into" the screen dimming mechanism to find out how long it will be until the screen is dimmed. If you want to be simplistic, you can check this in your timed entry to see if the screen is dimmed and quit if it is. Each individual could then adjust the time through the Preferences panel. If you don't want this, you can STILL use this mechanism. Just keep track of the maximum value returned (it measures minutes to autodim) and any time it returns 10 less than the largest value you've seen, quit. -- Blake W.

You have to subclass BrowserCell and add an ivar. The 'tag' and 'setTag:' methods are prototyped in the Cell class, but subclasses are responsible for allocating the storage to remember tag values. Here's the code: ------ begin AfsBrowserCell.h ------ #import <appkit/NXBrowserCell.h> @interface AfsBrowserCell:NXBrowserCell { int tag; } - setTag:(int)aTag; - (int)tag; @end ------- end AfsBrowserCell.h ------- ------ begin AfsBrowserCell.m ------ #import <afskit/AfsBrowserCell.h> @implementation AfsBrowserCell - setTag:(int)aTag { tag = aTag; return self; } - (int)tag { return tag; } @end ------- end AfsBrowserCell.m ------- Then in code, before loading the browser, you just say: [theBrowser setCellClass:[AfsBrowserCell class]]; -- Gregory H.

In my main program, I put this palette in my interface with IB. Then in my code, I accessed one of the palettes methods, called setTheColor:(NXColor)theColor. When I compiled the code I got an error saying: Could not find method setTheColor:..... I was boggled by this because I DID include the palettes object file (.o) in project builder. To solve this problem, I simply copied one of the palette's header files which contained the setTheColor: method. I put this file into the project directory (I didn't even add it to project builder, I just copied it into the project directory). Then when I compiled the code, it worked. QUESTION: Why should you have to include a header file from a palette? I thought palettes were supposed to be portable, with only the palette itself plus the palette's object libraries needing to be distributed? Why did I have to copy the palette header file into my project directory for it to compile properly? Is there a way to avoid this so I don't need to distribute source code if I choose one day to give the palette to someone? Thanks, Eric

I had assumed that clicking in the browser would make it so. *WRONG* If there are other things in the same window that can be first responder, they may not let go easily.

I've had to redo parts several times, so I am not sure what all I did and what order things need to be done in, but I figure these lessons might be helpful to others. Note that compiling GNU software is not for the faint of heart or limited of disk, so be warned. 1) Build gcc 2.4.5 You can't use old G++ with a new libg++ 2) Get and unpack the libg++2.4 3) Configure next libg++ recognizes next. (some GNU things, like GDB, do not :-() 4) Now, make the following changes: a) Change the Makefile to use CC=gcc (this is more important for the support libraries, not libg++ itself) b) Add "-DSTDC_HEADERS" to the CFLAGS variable c) In the _G_config.h file in the libg++ directory, modify the following two variables to "1" from "0": #define _G_NAMES_HAVE_UNDERSCORE 1 #define _G_DOLLAR_IN_LABEL 1 Hope this helps. GNU only has 'bsd-next-m68k' (and intel, possibly), so I'm not sure if these things vary with release number, or how to tell GNU about how to change it. -enp -- Ernest N.

[in .m file:] valGaugeImage = [valGauge backgroundImage]; Imagine if you will a balance (to measure mass) and on this balance is a gauge. As the balance is tipped one way or the other, the scale is oriented with the same angle as well (the gauge is mounted on the "main airm" of the balance). How do I rotate the view of the guage (or more specifically, an NXImage)? I know it's possible to flip them, and it's possible to rotate the coordinate of the window (or is it view?). Anyway, on top of all of this, the weight on top of the scale will have to be rotated and positioned as well. [softly] help! ----------------------------------------------------------- David A.

The quick and dirty hack is to set the delegate manually, bypassing Objc encapsulation and directly messing with the icon window's instance var for delegate.

This is how apps like Edit.app accept dropped file icons, so it is more consistent with the NeXTSTEP UI guidelines. // This is used to avoid hanging the workspace for the duration // of whatever would be called out of the app:openFile // I probably could have used perform:with:afterDelay as well ... void iconReleasedHandler (DPSTimedEntry tag, double now, void* user) { id self = (id) user; // Do whatever you want (filename saved in path instance var) ...

This version implements all of the functionality I'd envisioned for version 1.0 and finally fixes a lingering bug that's been in the kit since the beginning. However, I would REALLY like some feedback from the net on the usefulness / desirability of the product before I put the final polish on it. Are there that few of you out there that are interested in writing a multithreaded application? Or am I just impatient :-) Since the beginning of time there seem to have been two major complaints about the AppKit: The Text object and the lack of thread-safety. I'm not brave enough to tackle the Text object just yet, but the thread-safety issue has been bugging me long enough that I'd just like to get the complaint safely behind us and move on. -- Blake W.

'swapfile' is the real swapfile, either compressed (in > this case you'll see swapfile.front, too) or uncompressed. O.K. (This is getting fun!) So, let's talk scenarios here: In case of nocompress, swapfile is _THE_ swap file. Simple. In case of no nocompress, swapfile.front is _the_ swap file, while swapfile is the _compressed_ swap file. Right so far? (It's what I understand from your post) Now, what I read about compressing the swapfile, it does one thing: reduce the amount of stuff you need to access in the swapfile by compressing it, therefore speeding the machine up. This makes sense if swapfile.front _replaces_ swapfile (i.e. it is just let to sit there until it is needed. Otherwise, you would have to write to both swapfiles, thus _adding_ to the data sent/received, and slowing things down. This does _NOT_ make sense to me. This would also explain, to me, that the swapfile does not grow in the exemple given earlier in this thread. It stays at 16 Megs, while swapfile.front grows to more than 28 Megs. Either it is being left alone, or Mach/Unix manages to squeeze it into half it's size using some (I guess) highly speed-optimized compression algorithm. Very good. Almost too good to be true. (one way to test this would be to grow the swap file to some _huge_ size, just to see how files react when you _CAN'T LOGICALLY_ compress into the lowat [ something like 60 Megs for the 16 Megs loat.

Basically, i'm trying to come up with a scheme for unique key generation. All keys are derived from a table that looks like the following. ENTITY HIGHEST KEY currently the highest key for this entity. Now, I'm thinking about how things will work in a multiuser environment. I'm trying decide exactly when I make changes to the database. eg. One person gets an id for a "lead" whilst another person is also creating a new "lead" I want to ensure that two people get different new lead id's. So I'm thinking I will generate the new lead id from the contents of highest key so I must change "physically" this area of the database before a "dirty" read occurs. This sounds pretty simple but what do I do if the first person decides they no longer wishes to create the lead and back out of the transaction. All subsequent leads are out by one now. So I guess I can just accept that I will not have an arithmetic sequence of lead id's and be done with it? How are you guys generating your keys under DBKit?

Now I'm not so sure. The program I'm writing will quite often be reading over 1000 objects "across the wire" (bycopy). I've just done some experiments, and reading across 1130 objects each of which encodes a unique character string (about 40 bytes each) takes 62.5 seconds. That's quite a while for a user to wait. As a benchmark, I tried archiving the same list of objects using NXWriteRootObject() to a file. Although this involves a similar operation, it only took 2.5 seconds! Multiply that by two for unarchiving on the other side and it suggests that there is at least the possibility for DO copies to be 10 times faster than they are at the moment. (I'm only concerned here with local connections on the same machine). 6 seconds for 1000 objects is acceptable. 60 seconds isn't. So what can be done? [At this point I went and tried another experiment]. Well sorry to waste bandwidth answering my own question, but other people may be interested in what I've just discovered. The 1130 objects in question were being copied across using FullCopyList which is an example in the DO docs. Now this encodes each object separately using encodeObjectBycopy:. I had reason to believe that each of these objects was being copied across one at a time rather than all at once. So I modified FullCopyList to send each object the encodeUsing: message itself and include the name of the class of all the objects so that they could be allocated the other side by using objc_lookUpClass(). This new way only took 3 seconds! Dave Griffiths

You get benefits from threads even without a MP. If you've only got one application active with one thread, when you do I/O it has to wait and those CPU cycles are wasted. With multiple threads, when one thread blocks for I/O, another one can continue using the CPU. But the main advantage of threads, at least in NeXTSTEP apps, is that they allow the main thread to continue responding to user events while some heavy processing takes place in the background.

Another approach, I suspect slower but simpler, is to rotate the View's drawing coordinates and tell the image rep to draw in a specific rectangle. I use: [self setDrawRotation: tempAngle]; [[theNXImageObject bestRepresentation] drawIn: &imageRect]; The only caveat to this is that you can't do it with an NXCachedImageRep because that doesn't have enough information to redraw itself properly. I've only used this with NXBitmapImageReps and it works REALLY well. I use it to draw a hand of cards that can be fanned out as if you were holding them in your hand. Along with this, as the previous poster mentioned, you may need to do translation of the origin using setDrawOrigin: to get the appropriate results.

I am desperately hacking on my first real application and I stumbled in a 'experience' problem: The App is an raster-oriented drawing program for working templates where the user depends on seeing the actual position everytime. Holding shift to see them temporarily is not applicable. So I started implementing a Coord-Display. My first approach were mouseMoved-Events that checked if the change was more than one grid-step and then updated the display. After looking at an idle-meter when moving around the mouse a bit, (0% idle) I decided that this was not the way to go. I have not found any example doing such stuff, so I tried another effort: A DPSTimedEntry: static void trackhandler(DPSTimedEntry tracktimer,double now,void *userdata) { DrawView *tmpview = (DrawView *) userdata; NXPoint pt; [tmpview->window getMouseLocation: &pt]; [tmpview convertPoint:&pt fromView:nil]; [tmpview->posDisplay setX: pt.x Y: pt.y]; } set off for every 0.1 seconds. This one is better (constantly 15-20% system performance) but I think there must be a better way. (I know there is DPScurrentmouse, but it is not documented [2.1]). Please, if anyone has implemented such a display before, can you please give me a hint or send me some piece of code ? The resulting app will be GNU-licensed.

OK, it's pretty unlikely we're going to have drivers written in Obj-C! > So what _is_ DriverKit? > > Dave Griffiths DriverKit is both a class hierarchy and runtime environment for writing device drivers (yes, you write them in Objective C). DriverKit has a base class (IODevice) that you subclass to write new drivers. The kit also contains subclasses of IODevice for various classes of device such as disks, displays, & ethernet cards. If you are writing a driver for one of these, you subclass the appropriate kit class and go from there. For example, if you are writing a device driver for a new framebuffer based display card, you would subclass IOFrameBufferDisplay and override about three methods and you're done. These drivers are dynamically bound into the kernel. The other major thing DriverKit gives you is a change in the way you handle interrupts. Instead of fielding interrupts directly in your driver, your driver can register interest in a particular interrupt and then wait for messages. DriverKit fields interrupts and dispatches messages to the registered driver thread. This allows the driver to be written without worrying about what it can and can't do in the interrupt routine. Of course, DriverKit does allow a driver to service interrupts directly if necessary. The model there is that the driver has a low level interrupt handler that does time critical work associated with the interrupt and dispatches a message to the device thread when some higher level processing needs to be done. For instance, the interrupt routine could read bytes from a device with a shallow buffer (avoiding overflows) and queue them in a higher level data structure. When that structure is getting full it would post a message that the high level device thread would recieve and process. This is a very high level overview of DriverKit and is by no means complete. I think some of the most interesting aspects of DriverKit are yet to come. The framework is there for some neat features in the future. Joe Pasqua

Is there any way to get around this? Can we somehow append to messageScrollText without making it the first responder?. I cant seem to find a way of doing it without using "setSel::","selectAll:", etc all of which make the scroll text the first responder.

This was a 3.0 bug that we depended on being fixed, but under 3.1, trigger-generated errors still don't seem to be recognized by the Sybase adaptor.

What do you mean "should consider"? 8-) As with many other wheels I and surely others have reinvented, a tagged browser cell class already covertly lives in the shared library that constitutes most of the AppKit. It would be nice if NeXT published some of the more useful classes that they have developed. Don't get me wrong: I don't think NeXT should have to document, test, and support every class and method used in the AppKit (or any other kit). That's the main point of encapsulation, right?

It has an icon for each of these file types, so that whenever I click on a file in the Workspace with that extension, Foo.app's icon for it shows. I'm trying to extend Foo.app to handle yet another file type: .foo. I am not supposed to have to recompile, so I haven't. I've put the file extension (without the period) in the iconheader, and dropped the new icon into the image suitcase in IB. If I fire up Foo.app and drop a .foo file into it, it works beautifully. Foo.app resides in /LocalApps. Now for the problem. In the Workspace the .foo file shows up with the generic document icon and if I double-click on it it's opened by Edit. If I pull up the Inspector, Foo.app is not displayed as an option for opening the file. How can I get the new icon to display in the Workspace for a .foo file? Like I said, no compiling is supposed to be necessary so I can't use PB. (Besides, I tried that already and PB did major surgery on the app!) Any help is appreciated!

"swapfile" is ALWAYS the physical swapfile. The size of this file tells you how much disk is being used by the swapfile. If you are using the standard paging mechanism then "swapfile" is also the logical swapfile. If you're using the "swaptomizer" to compress the swap then "swapfile.front" is the logical swapfile. In this case the size reported for "swapfile.front" is only the logical size of the file. It does NOT exist in that form on the disk, only in compressed form inside the physical swapfile. > Now, what I read about compressing the swapfile, it does one > thing: reduce the amount of stuff you need to access in the > swapfile by compressing it, therefore speeding the machine up. > This makes sense if swapfile.front _replaces_ swapfile (i.e. it > is just let to sit there until it is needed. > > Otherwise, you would have to write to both swapfiles, thus > _adding_ to the data sent/received, and slowing things down. > This does _NOT_ make sense to me.

I'm trying to create a very simple multiplatform program using curses. I've successfully compiled and run the code under Ultrix (Dec unix) but fail to do so on the NeXT. First, I have very little documentation and have read what I have. I am using NeXTSTEP 3.0 on black hardware. The two things I'm puzzled about are: - setting a signal function to intercept an interrupt. According to the examples, this ought to be something like: #include <signal.h> trap(sig) int sig; { endwin(); exit(sig); } /* trap */ and the call to install the function: (void) signal(SIGINT, trap); (This will give me a compiler warning about incompatible pointers; I havn't yet figured out what the declaration must be in order to avoid this.) As I said, this works fine under Ultrix, but bombs on the NeXT (bus error). What am I doing wrong? - the implementation and use of curses. According to the manuals, I should issue 'initscr()' before the first use of any curses library and 'endwin()' after the last. The NeXT doesn't seem to have 'endwin()'! Is this correct? In order to read a character through the current window, I should use something like (action is an int): action = wgetch(window); but here the compiler claims that I am not ignoring a void 'return value' - if wgetch() doesn't return any value, where do I get the character read from? Any help greatly apreciated.

I am programming with the djgpp port of GCC for protected mode in DOS, so code written assuming a UNIX GCC ANSI compiler would be perfect. If it requires many trig functions and other such calculations I would prefer that it look them up from a table rather than calculate them. Memory usage is not an issue - SPEED IS! If there is a better way to lay out the data, feel free. In the finished application, I would like to be able to drag around the directional vector tip (with viewing coords in tow) while specifying what is "up" as an angle from the Z axis. I would like as much of it as possible to be integer math, of course. The Transform() function just takes viewing data and a 3D triangle and spits out the 2D triangle coords...

The client frees the object by sending a free message to the object's proxy. So far so good, everything works fine. However, when I look at the server using MallocDebug the object allocation shows up as a memory leak, i.e. the server's object isn't being freed! According to the D.O. documentation, the server's object should be deallocated when the reference count on the object drops to zero. I have checked the reference count immediately before calling free and it is 1. So what gives? Why isn't the REAL object being freed? It is easy to reproduce this problem. Try the following: Write a server with a "- doit" method that returns an NXData instance by reference. Write a client program that connects to the server, calls "- doit" twice, each time freeing the NXData instance immediately. You have to call the server's method twice in order for MallocDebug to register the first allocation as a leak. This error occurs for all classes I have tried not just NXData. It also occurs on both Black HW running 3.0 and on White HW running 3.1 Pointers?

Of course that would be a pain in the but... Another thing that you could do would be to create a category to overwrite the -superViewResized: method. This might be nicer. If you are worried about keeping everything kosher, choose a "spring" configuration that you would never use: i.e. all springs on. Then inside your - superviewSizeChanged: method (this is the actual name, I was working from memory above), you could look at the variable ... Well, shoot, I can't find the variable name, but it is the one set by the: setAutosizing: method. Anyway, look at the variable and compare it to all of the masks ORed together. If it is that one, do your own resizing, otherwise send the message on to super. I realize that this is sketchy, but it is actually a really good exercise in using classes and categories. Kevin

My program has a main menu, with a save option. This button isn't enabled until a display object is create,but the display object is created by a handler object which is created by the data object which is created by the application object ( the home of my main menu ). Are you confused yet. My point is I want the 'save' method in the display class, ie receive the message from the main menu. I've tried using the First Responder, but I can't seem to get it to work. I've seen the F.R. work for GRAPH, but that's save's method was in the object created by the home of the main menu. If you understand what I just wrote, any suggestions would be a big help to this NeXT newbie. Thanks, Anthony Grandy lisag@ac.dal.ca (vax) Sorry NO NeXT mail

I received several basic solutions: 1. change the modem config so that it ignores dtr (which is cleared when you exit a pgm). But: I wanted a modem independent way. 2. many ioctl's take a 3rd parameter which is 0 or 1 which turns that off or on. #define TIOCHPCL _IO('t',2) /* hang up on last close */ But: TIOCHPCL ignores that 3rd parameter (and it's not documented that way). 3.

Make the window larger and drag a button to it. Make a matrix of buttons. Now you set the button titles to the commands you want to send to the subprocess. Connect the matrix to the Coordinator Instance with the sendActionToSubProcess: method. If you click one of the buttons, the command (Button title ) is send to the subprocess and executed. if you have just on button, not a matrix you have to make a change in the sendActionToSubProcess:sender method. Change in the first line const char *buffer = [[sender selectedCell]title]; to const char *buffer = [sender title]; ok, I hope this helps you a little.

I could certainly believe, however, that the pole >display is a POS (NOT meaning Point of Sale), and the manufacturer was full of >it (but the documentation with the display also said it required two stop >bits). This is a really gross solution, but it the actual output rate isn't that critical (that is, you don't have a lot of data to move), then there is a work-around. Just send stuff out the serial port one character at a time with a very small delay between characters. This will give you plenty of idle/mark time on the serial port before the start bit of the next character. It may be that if you just do write() systems calls, with one character at a time that you'll get enough delay. Alternatively, something like this may work for you: void slow_puts(int ttyfd, char *s) { struct timeval tv; while (*s) { (void) write(ttyfd, s, 1) != 1) { tv.tv_sec = 0; tv.tv_usec = 1000; /* 10 milliseconds */ (void) select(0, (fd_set *)0, (fd_set *)0, (fd_set *)0, &tv); ++s; } } Of course, you'd need to add error checking, etc.. The use of select() for doing a delay may not strictly be correct, since it won't be restarted if its interrupted by a signal. On the other hand, you'll probably still get enough delay.

I did include -lc++ without any success. > (The same code compiles fine on ultrix OS when g++ is used.) This is a common C++ question. C++ does name mangling. If it sees a definition of a function it assumes that the function is in C++ has it's name mangled. So when C++ reads stdio.h it sees: extern int printf(const char *format, ...); assumes it is a C++ function, and tells the loader to look for the mangled name: _printf_FPCce. Unfortunetly, that's not what you want since printf is a C function not a C++ function. The solution is to tell C++ that it is a C function by doing: extern "C" { #include <stdio.h> } This says that everything in stdio.h is actually C not C++. That leaves the question of why it worked on <fill-in-the-blank> other computer. The answer to that is that they have probably modified the headers to add the extern "C" for you. Some vendors have started modifying their headers to say: #ifdef __cplusplus extern "C" { #endif <<< regular stuff in here >>> #ifdef __cplusplus } #endif Which makes the header work transparently for either C++ or C, but NeXT hasn't done that yet.

DBKit has nothing to do with it. The server database must support this capability explicitly. We use Oracle sequences, which work just fine: SELECT KEY_SEQUENCE.NEXTVAL FROM DUAL It's a little bit tricky to do this under DBKit. DBDatabase and the Oracle adaptor will not generate the right SQL even if you manage to create a model with an entity DUAL and attribute KEY_SEQUENCE.NEXTVAL (they insist on aliasing DUAL as t0). It is easier in any case to drop down to the binder level, where half a dozen DBKit calls will do it for you: id database = [DBDatabase findDatabaseNamed:"X" connect:YES]; id binder = [[DBBinder alloc] init]; id propertyList = [[List alloc] init]; id keyValue; int uniqueKey; [binder setDatabase:database]; [binder evaluateString:"SELECT KEY_SEQUENCE.NEXTVAL FROM DUAL"]; [binder setNext]; [binder getProperties:propertyList]; keyValue = [binder valueForProperty:[propertyList objectAt:0]]; uniqueKey = [keyValue intValue]; [binder cancelFetch]; [propertyList free]; [binder free]; [database free]; And there you have it. Sorry, I don't know if Sybase has anything analogous to Oracle sequences. -- Ron

I think the problem is that when you click, the Matrix is actually processing the click, not the underlying button. The matrix takes care of highlighting one and unhighlighting the other (assuming that the matrix is in "radio" mode, that is). When you grab the button underneath, it doesn't know it's in a matrix (thanks to OOP), so it just does what it thinks it's supposed to do when clicked, which is to change state. You should use the matrix method for setting the button you want highlighted, rather than getting the ID of the button and doing "performClick:" Something like one of these: [myMatrix selectCellWithTag:YOUR_TAG_HERE]; [matrix selectCellAt:yourRow :yourCol]; That should work a bit better. -- Glenn Reid NeXTmail: glenn@rightbrain.com RightBrain Software 415-326-2974 (NeXTfax 326-2977) Palo Alto, California Electronic Frontier Foundation, member #054

First of all, the information I'm presenting comes from: /NextLibrary/Documentation/NextDev/Concepts/Pre3.0_Concepts/ 07_ProgDynam.rtfd ... where you can read up on the subject at leisure. In order for a view to receive messages directed at the first responder, it must first BE the first responder (oversimplification, see below). A view will, by default, not become the first responder when the user clicks on it. In order to change this behaviour, the view should implement the following method: - (BOOL)acceptsFirstResponder { return YES; } Now, clicking on the view and sending messages to the first responder should work. HOWEVER: From reading your documentation, I don't think this is what you wanted. (I could be REALLY wrong). The problem with the mechanism described is that if the user selects a window containing the view without selecting the view, your save: method won't do anything. The actual path of action message in the reponder chain is described the aforementioned documentation as follows: When the target of an action message is nil, the Control that's about to send the message must look for an appropriate receiver. It conducts its search in a prescribed order: - It begins with the first responder in the current key window and follows nextResponder links up the responder chain to the Window object. After the Window object, it tries the Window's delegate. - If the main window is different from the key window, it then starts over with the first responder in the main window and works its way up the main window's responder chain to the Window object and its delegate. - Next, it tries the Application object, NXApp, and finally the Application object's delegate. NXApp and its delegate are the receivers of last resort. You probably want to implement it in your window's delegate (heck, you may just want to make your view or its controlling object the window's delegate and get it over with).

This API would be public domain with the hopes that we might finally see an end to the "and another 20M for *our* spell checker" feature of a lot of software available today. If there were a widely available cross-platform spell-check API with adequate features, a spell-check client could determine at install time if there's already a compatible spell checker available and avoid installing its own spelling checker. There would obviously be some administrative calls: load_spell_checker unload_spell_checker find_spell_checker [install-time] etc. And actual use calls should be fairly straightforward as well: set_language check_word etc. Some data structures will need to be defined, etc. It would be nice if there was the potential for context-sensitive spell-checking, but I'm not sure if that's possible in a generic environment. Perhaps if the calling application were to provide words on paragraph at a time (that would be a reasonably small lexical object which the application could be assumed to understand. Sentences are notoriously difficult to isolate because of the overloading of the period--that sort of parsing would be up to such a "smart" spell checker). The API would consist of a system-independent (or as nearly so as possible) header file plus stub routines to convert API calls into the appropriate form for each operating system. Any suggestions/comments would be welcome. The newsgroups line is lengthy so I've redirected follow-ups to comp.text. Of the groups listed I read only one or two so I would recommend making sure that that's where follow-ups end up. E-mail responses should go to dhosek@hmcvax.claremont.edu. At present, I don't imagine that this will be too terribly complex (unless I've overlooked something which is always possible) so I'd expect that such an API could exist before summer's end. -dh Don Hosek Quixote Digital Typography 909-621-1291 dhosek@hmcvax.claremont.edu

I see no need. I've written a lot of "portable" code (and I've been using NeXTs pretty intensely for over 4 1/2 years) and I'd never run into any nontrivial problems prior to the stupidities introduced in 3.0. Until then, I found the NeXT to be an outstanding development environment, particularly because the compiler and runtime system were so intolerant of bozo code. Now I find myself spending a lot more time using SunOS 4.1.3, and find it very difficult to recommend NEXTSTEP to anyone in the UNIX market looking for a single-platform solution. >I would think it would make it much easier for folks to port from Sun et al >to NeXT if include files like unistd.h and others to facilitate this. It's that kind of misguided logic that got us into trouble in the first place. Better someone would put together some guidelines on how to port code to the NeXT--or, better still, how to make it "NeXT-friendly" from Day 1. You'd be amazed how many people don't know about cc -bsd and go through amazing gyrations trying to get "code that works fine everywhere else" to function under the bogus pseudo-ANSI paradigm. The growing POSIX infection is only going to confuse matters further. >What do you folks think? Would this be a "good" thing for NeXT to spend a >little time providing to make life simpler for their developers? I think NeXT should spend a little time taking what they have and making it work, and less time kissing up to the "checklist" mentality. If you want things "to work like Sun intended," buy a Sun! Buy thousands of them! Stop trying to fix what ain't broke. -=EPS=-

There are often things you need to do repeatedly within an object's body of code that are peculiar to the implementation that object and don't need exposure. Since the only way to functionalize in Smalltalk is to create a method, some kind of private status is *desirable* to maintain the abstract interface and prevent abusive coding by people who don't know enough to stay away from the implementation details. The situation isn't as bad in C++ or ObjC, since you can always write a static function instead of a method, but I think the public/protected/private trichotomy is one of the things that's *right* about C++. As for Smalltalk source being published, well, it's pretty hard to prevent decompilation of Smalltalk in a development environment, so the source is provided because everybody's going to get it anyway.

I'm sure everyone will agree, that this kind of bug should not occur under NeXTSTEP Intel, especially if it is brought out by a program as frequently used as Draw.app. BugVersion: 6 Topic: Draw Title: Intel specific bug in getNextEvent in Draw.app. (Causes postscript error) Severity: Unavoidable Bug Architecture: General Reported_Version: thunder4h Submitter: charuhas Sites: Harvard Univ. Div of Applied Sciences Description: To recreate the bug: 1. Compile Draw.app (i386 only) (The problem does not occur on my black box) 2. Start drawing polygons. 3. After about 3 to 5 polygons you cannot draw them anymore. The following appears on the console log: PostScript program error, DPSContext 3cc958 Jun 23 10:47:52 virtualpc2 Draw[3101]: %%[ Error: undefinedresult; OffendingCommand: bin obj seq, type=129, elements=10, size=93 ]%% I narrowed it down to the getNextEvent in the modal loop of the file Polygon.m. Line #182 if (!done) { while (event->type != NX_MOUSEUP) { p = event->location; [view convertPoint:&p fromView:nil]; [view grid:&p]; [view drawSelf:&r :1]; getRectFromBBox(&r, p.x, p.y, last.x, last.y); [view scrollPointToVisible:&p]; NXInsetRect(&r, -2.0, -2.0); [self draw]; PSmoveto(last.x, last.y); PSlineto(p.x, p.y); PSstroke(); [window flushWindow]; ----> event = [NXApp getNextEvent:POLYGON_MASK]; } if (fabs(p.x-start.x) <= grid && fabs(p.y-start.y) <= grid) { done = YES; closepath = YES; } } This is a serious problem for me, since I have created a program based on draw (for configuring network topologies) and I use some of the polygon code with equally bad results.

The spell checker should fetch the user's default language (ir any) BUT be re-setable from the client application for alternate languages. The spell checker should run on an abbreviated database with encoded pre-suffixes, produce a BOOLEAN return for FOUND exact spelling, and have a list of similarly SOUNDING words available once the lookup fails. All returns should reference the call in some way so that multiple parallel calls may be sorted out by client tasks. Norton TeXTRA (MS-DOS application) has an excellent spell checker for DOS for anyone who learned to spell in the last 20 years or so (phonetic as opposed to rote memorization). Under NEXTSTEP, it should accept Mach calls and also be able to efficiently work on a list from disk or passed out-of-line as data (i.e. mapped to an NXStream). Under any BSD system it should accept Piped stdin/stdout. It should receive hyphenated words for check as either a strung-together construct, single or many worded end-of-line style and allow for broken (hyphenated) words as well, and preferably define both an optional and forced hyphen character. Under NEXTSTEP (and probably Mac and Windows?) it should accept single inquiries via Pasteboard server as well. On multitasking systems, it should be properly multi-threaded so that calls from multiple programs, or even multiple calls from the same program -- or multiple calls from multiple users could be received and replied to in reasonable time without garbling the results, or just being ``unavailable'' under heavy usage. Unloading should be system-dependant. On fast-load VM based systems, with core-image memory re-loading, it should unload whenever it has no client services in process. On others, it may require a separate load/unload. NEXTSTEP, services can merely summon it when called for, for example, the OS loading it to perform an advertised service. A secondary task should be able to format lists of words and manage handing that list to the server API task. If implemented under non-multitasking sytems such as MS-DOS, it could require a shell-to-DOS or separate launch of this secondary program. It should be possible to specify virtually any number of look-up databases. It MUST provide an efficent method of adding to these databases, or building new- efficient- to-use databases, before ANY shutdown except forced system shutdowns. It should have a scratchpad so as to not lose such additions in case of forced shutdown or system crash while servicing other requests, having not yet updated the additions.

Does this mean that the card *must not* use paging? Specifically, my card (an S3 86C911) has a 64K window starting at 0x0A0000H. Does this mean it's unusable? (Incidentally, this is the chipset immediately _before_ the S3 805 chipset driver included with NS/FIP) There is also a method described in IOFrameBufferDisplay called "mapFrameBufferAtPhysicalAddress:length:" which leads me to belive that it is possible to get away with a "window" into the video card memory. Does anyone have any ideas as to: 1) Is it possible to write a driver for this card? 2) Must the video card _not_ use paging?

After two weeks of hunting through explanations and trying to get help on this, I got a quote from NeXT that: "Third-party developers should not try to subclass the IODisplay class directly and should only subclass the IOFrameBufferDisplay class. A new class to provide possibilities for writing segmented VGA drivers might be in 3.2" As the frame buffer display class only does support adapters that can map their entire display memory into a linear CPU memory space, that ended my efforts. I had tried to disassemble the tseng4000 drivers to see how they were doing it, but it's very difficult. For a start, there are two tseng4000 drivers. I would guess that they have some unpublished protocol.. There has been some speculation on how it could be done. One method is to use page faults on a virtual memory range to swap video pages. However, this method is not all optimal for the S3-911, as it has relatively slow direct memory access times. It's much faster if you could use the hardware fills, copies, and scrolls. But I can't see anything like that coming along. At most we might be able to use the hardware cursor. It's strange that I've used my orchid card under windows and NT with no problems, in 1024x768x256 mode. Now I should use 640x480x2. The "alternative" is buying another card. sigh. I hope I'm wrong about this and that it really is possible to write a driver for the 911. If so, can someone please tell me, and the rest of us with "obsolete" video cards too. Ari

You seem to know all the answers. Is there a reference to point me to? (Other than the zs(4), tty(4), ioctl.h include file). strangely enought, the above always returns 0 for me. and I checked the return from ioctl and it wasn't -1. TIOCMODG always sets the statusByte to a 0 (and works the same for an int). I figured out the behavior of my code. It wouldn't detect a change during the running of the program. It preserved the value of those status bits from when you ran the program. You would have to exit the program and re-run it to get it to update the modem status bits. The solution was to reopen the port, read the status bits from the new tty, and then close it. The strange thing was that after doing this, the next time I read the status bits from the old port they would be correct. Has anyone seen this? (Note that I tried reading it twice without reopening the port and this didn't fix the problems). here's my code that works. - (BOOL)carrierDetect { int result; int temp_tty; ioctl(ttyNum,TIOCMGET,&result); /* old tty, never changes */ printf("oldtty: %o\n",result); temp_tty = open(portString,O_RDWR|O_NDELAY,0); /* open temp tty */ ioctl(temp_tty,TIOCMGET,&result); /* get new status bits */ close(temp_tty);/* close port */ printf("newtty: %o\n",result); return (result & TIOCM_CD) == TIOCM_CD; } Strangely, as I said above, the first time I call this, the oldtty reports the conditions when I first ran the program. but, after opening and closing the port, the next time the old reports the correct info. It seems that the port must be opened and closed for this info to be updated. Perhaps that has something to do with the way that I opened the port (same as above, open("/dev/ttyfa",O_RDWR|O_NDELAY,0); ) -nick

I register an object *)using [NXConnection registerRoot:<myobj> withName:<myname>]. *)The returned NXConnection is run as [<myconn> runInNewThread]. The object implements NXReference protocol (I have problems with this too !); Another process connects to the root object *) using [NXConnection connectToName:<myname>]. The shared object responds to messages, but I have PROBLEMS FREEING IT. This is what I do while freeing : 1. The client (remote app) frees its proxy first using [<myproxy] free] 2. The server frees the object subsequently using [<myobj> free]. Now, I expect that the object as well as the NXConnection over which it was vended are freed ; I also expect that I can register a new instance of the class WITH THE SAME NAME <myname>. However THIS DOES NOT HAPPEN. The client process gets a return value of nil when [NXConnection registerRoot:<newinstance> withName:<myname>] is called. Why should this be so ? Does the name not get purged from the nameserver tables ? I've TRIED EVERYTHING (almost :-)). I did a [NXConnection removeObject:<myobject>] in the server's free method. I did a [<myconn> free] in the server's free method. I even tried [<myconn> deallcate] because the docs for NXInvalidation Notifier class says that only deallocate REALLY frees an NXConnection Only when the server process exits, is another process able to use the name <myname> to register an instance. So I feel the problem is to do with the process that first uses a name to register an object with the nameserver. The proxies I think are getting freed. BTW, the docs say that a class method (+removeObject of NXConnection) returns self ? Is this possible. Is DO in 3.0 NeXTStep BUGGY ? I'm at my wit's end (again). ANYONE HELP ... -gopal

From <sys/ioctl.h>, given that #define TIOCM_CAR 0100 /* carrier detect */ #define TIOCM_CD TIOCM_CAR makes both these piece of code effectively the same, I think there's something missing here, somewhere. Anyway, to add my two cents, I use the same approach mentioned in the two (basically identical) examples above, EXCEPT that I use TIOCMGET. It seems to work OK for me. Note that I'm using this on /dev/cuf?, for whatever difference that might make. I don't recall right now why I choose TIOCMGET rather than TIOCMODG other than that's all that was there when I wrote the code. The code is exactly: if (ioctl(dialfout, TIOCMGET, &modemstat) < 0) syslog(LOG_ERR, "makecall: Can't TIOCMGET, %m"); else if ((modemstat & TIOCM_CD) == 0) { syslog(LOG_NOTICE, "makecall: Outbound interface \"%s\": lost carrier", device); hangup(0); /*NOTREACHED*/ } Actually, one interesting difference is that the first code fragment does ioctl(foo, TIOCMODG, &integervar) and the other does ioctl(foo, TIOCMODG, &charvar) I would expect that the first example would be the correct one, since this ioctl is defined to take an (int *) as a parameter rather than a (char *). I think that I see byte order brokeness potential looming here... -- Louis A. Mamakos TransSys, Inc.

TIOCMODG always sets the statusByte to a 0 >(and works the same for an int). This is just weird. After my previous posting, I decide to go investigate just what TIOCMODG and TIOCMGET are and how they differ. The tty(4) man page on the NeXT is silent on these. I then consulted the various bibles on these sorts of matters: Leffler, McKusick, Karels, Quarterman, "The Design and Implementation of the 4.3BSD UNIX Operating System", Stevens, "Advanced Programming in the UNIX Environment" Stevens, "UNIX Network Programming" these were also lacking in helpful advice in this area. Now, having just watched the Star Wars trilogy on the SciFi channel on cable, I recalled the hacker's motto: "Use the source, Luke." I then grepped the source for NET2 and NetBSD (derivitive from 386BSD which is derivitive from NET2). This is a likely path to pursue given that the non-pure Mach part of the kernel appears to be something close to the NET2 BSD code. (At least if you match up the bugs and features). I think I have gotten to the bottom of what's going on. For those of you that don't skip to the last page of mystery novels to see "who did it", read on. Or skip to the end if you're bored by kernel drivers, etc. [Begin long digression into the kernel-level implementation of tty drivers] The BSD sources were somewhat more helpful. There is, of course, no code in the tty.c module since these are likely functions implemented by the hardware drivers rather than the higher level drivers. Happily, in the NET2 code there are drivers for 386 standard ISA COM port serial ports. There are also drivers for a few HP serial drivers. Both of these implement TIOCMGET to return something useful; neither had any code to implement TIOCMODG. For example, the i386 COM port driver has code like this: comioctl(dev, cmd, data, flag) dev_t dev; caddr_t data; { register struct tty *tp; register int unit = UNIT(dev); register com; register int error; tp = &com_tty[unit]; error = (*linesw[tp->t_line].l_ioctl)(tp, cmd, data, flag); if (error >= 0) return (error); error = ttioctl(tp, cmd, data, flag); if (error >= 0) return (error); com = com_addr[unit]; switch (cmd) { [...] case TIOCMSET: (void) commctl(dev, *(int *)data, DMSET); break; case TIOCMBIS: (void) commctl(dev, *(int *)data, DMBIS); break; case TIOCMBIC: (void) commctl(dev, *(int *)data, DMBIC); break; case TIOCMGET: *(int *)data = commctl(dev, 0, DMGET); break; [...] } Looking at commctl.. commctl(dev, bits, how) dev_t dev; int bits, how; { register com; register int unit; int s; unit = UNIT(dev); com = com_addr[unit]; s = spltty(); switch (how) { case DMSET: outb(com+com_mcr, bits | MCR_IENABLE); break; case DMBIS: outb(com+com_mcr, inb(com+com_mcr) | bits | MCR_IENABLE); break; case DMBIC: outb(com+com_mcr, inb(com+com_mcr) & ~bits | MCR_IENABLE); break; case DMGET: bits = inb(com+com_msr); break; } (void) splx(s); return(bits); } We see that it indeed grabs some bits off the com port control register, which presumably map one-to-one with the various TIOCM_* definitions. I've seen other drivers where there is a mapping function betwixt the TIOCM_* bit and what the hardware returns. This preserves the model of the virtual DH/DM-11 hardware (UNIBUS, anybody? :-) --- begin tangent --- In the NET2 code, interestingly enough, if you look at the hardware bits and the ioctl.h definitions, you don't see too many matches!

Perhaps this was meant to be defined to return a "generic" representation of the device status bits, rather than (what appears to be) a direct set 'o bits right off the hardware that TIOCMGET returns. Now, I don't know what the NeXT actually does with the TIOCMODG ioctl(), it appears to do the "right thing" with TIOCMGET mapping at least the bit that corresponds to the hardware DCD signal to TIOCM_CD. I have code that seems to successfully use TIOCMGET and checks against TIOCM_CD; it does this once per minute and it seems to do the ``right thing.'' So, I hacked up this silly program: #include <sys/ioctl.h> main(int argc, char **argv) { int fd = open (argv[1], 0); int foo; if (fd < 0) { perror(argv[1]); exit(1); } if (ioctl(fd, TIOCMODG, &foo) < 0) { perror("TIOCMODG"); } else { printf("TIOCMODG: 0x%x\n", foo); } if (ioctl(fd, TIOCMGET, &foo) < 0) { perror("TIOCMGET"); } else { printf("TIOCMGET: 0x%x\n", foo); } } and ran it on a 3.0 system: louie[146] $ a.out /dev/cub TIOCMODG: 0x0 TIOCMGET: 0x66 louie[147] $ a.out /dev/ttyb TIOCMODG: 0x0 TIOCMGET: 0x66 louie[148] $ a.out /dev/ttydb TIOCMODG: 0x0 TIOCMGET: 0x66 and on a 3.1 system: # ./a.out /dev/cub TIOCMODG: 0x0 TIOCMGET: 0x46 # ./a.out /dev/ttyb TIOCMODG: 0x0 TIOCMGET: 0x46 # ./a.out /dev/ttydb TIOCMODG: 0x0 TIOCMGET: 0x46 I conclude from this experiment that TIOCMODG really isn't doing much of anything. The values we get back 0x66 == 0146 == <TIOCM_CAR,TIOCM_CTS,TIOCM_RTS,TIOCM_DTR> and 0x46 == 0106 == <TIOCM_CAR,TIOCM_RTS,TIOCM_DTR> are consistant with an open line (with nothing plugged in for 0x66 and the device turned off for 0x46). Thus, I assert that TIOCMGET looks like its returning plausable values. What I think is going on here is a kernel bug that's biting us: the TIOCMODG ioctl is probably failing, but the error status is not being returned to the user. This could be a bug that I reported in a October 1991 where a user-installed line discipline (e.g., SLIP) can't return an error on an ioctl() that it implements.

And now I get this: $ ./a.out /dev/cub TIOCMODG: 0x0 TIOCMGET: 0x46 TIOCBOGUS: 0x0 It appears that any random, bogus TTY ioctl will return a 0 in the parameter passed by reference in the third argument of the ioctl.

Did Indexing Kit turn out to be robust? Was it fast in comparsion to standard relational databases as Sybase and Oracle, especially for large amounts of data? I'm building a large database app based on Indexing Kit and am finding it difficult, possibly due to bugs and limitations with Indexing Kit. I really appreciate your feedback. -Mike P. Also, for Indexing Kit experts only, two important technical questions: To use Indexing Kit to store a network of Objective-C objects, normally connected to by virtual memory ``id'' pointers, will I have to manually (in code) translate every id (instance variable) to Indexing Kit ``handles'' where ever I would want to load an object and NOT immediately load everything it points to until it is needed? (An NXTypedStream would load everything an object pointed to, I believe.) I don't suppose there's a proxy mechanism for this lazy loading, similar to Distributed Objects' proxy mechanism, say? I take it Indexing Kit doesn't have full relational join support? To do a relational join between two or more ``tables'' of objects, will I have to set this up myself manually, using IXPostingCursors I suppose? E.g., suppose each employee record had a ``boss'' field pointing to the employee who was his/her boss, and I wanted to process the query, ``List each employee and for each, all the employees under him/her''.

A lot of driver's such as HD, Tape and Ethernet drivers are very time critical, too much latency and you miss events (such as the next sector) and you introduce a long delay (such as a disk rotation). If you have 'core' drivers in the system which do this your system performance goes out the window. If you're running NeXTSTEP with NFS or AFS (I do) you want 105% performance from your network driver. Yes, this kit sounds really good for all those strange devices like scanners, digital cameras etc that people need to hook up but I think we're going to suffer from 'hacked-up' drivers for a while to come.

I thought palettes were supposed to be portable, with only the palette itself plus the palette's object libraries needing to be distributed? Why did I have to copy the palette header file into my project directory for it to compile properly? No. The only way the compiler can tell it knows a method is by reading its interface in a .h or .p file. however, if you don't, you will get a warning and the compiler assumes the return type for your method is id. (Note that the compiler is stupid too because even if it knows prototypes it does not correctly promotes type sometimes, but that's another thing). Is there a way to avoid this so I don't need to distribute source code if I choose one day to give the palette to someone? No and yes. You can't avoid distributing your interface if you want people to use it. But you're not distributing the source code, only the .h and the .o file, not the .c which is the only thing you want to protect. Remember that a .h is just advertising the capabilities of the class, but it does not get a clue about how the class is implemented (well, it should not). What about NeXT supplying all the libraries without a single .h file? It would be the same. You don't have to worry about distributing a .h file, it does not say anything about what you are wanting to protect.

Newsgroups: comp.sys.next.programmer From: peter@corsica (Peter Eisch) Subject: DistributedObjects and UNIX fork() Message-ID: <CAFE3r.28F@news.cis.umn.edu> Summary: DO don't like eating with forks Keywords: Distributed Objects fork UNIX Sender: news@news.cis.umn.edu (Usenet News Administration) Organization: University of Minnesota Date: Mon, 19 Jul 1993 18:58:22 GMT I'd appreciate a little insight to why this doesn't work or if someone can positively say that it's a bug. Background: The program is a daemon that would typically be launched from rc.local on boot. It registers an object and runs there forever. Problem: If I check to see if someone is already registered with my name, I can't use DistributedObjects after a fork. More specifically, if I try to connect to an object, even if it returns nil as it can't find a vended object of that name, I can't register an object with that name. Goal: The design needs a daemon to run reliably. It needs to be updated occasionally for various circumstances. As an example, a part of an important database may need to be taken off-line for a period of time so a different program (a 'placebo') that ignores the part of the database being serviced. The 'placebo' in it's launching connects to the running server, tells it to quit, and then registers itself with the appropriate name. Design: The daemon begins by processing it's commandline arguments, if any, and initializes its defaults database from the appropriate file. If initialization happens correctly, then we try to find the running server. If we get a proxy back for that name, then we tell it to quit. If all goes well at this point, we fork() and continue execution in the child. We first ioctl the tty then close the stdio fd's before vending our object. Once vended, we simply let it -run. Results: If anything is done with DO before the fork(), it renders my vending as useless (returns nil). Whether I connect to the running vended object or not this is the result. Further, it has nothing to do with registering the same name (I've tried bogus, contrived names before the fork that couldn't possibly match the intended name to be registered under). For what it's worth: The object that I'd like to vend is created before fork() and still behaves (as you'ld expect) after the fork(). code in a nutshell: main() { // optarg and intialization stuff while (server = [NXConnection connectToName:"bogusPonens"]) { [[Console new] logf:"%s found running..", defaultName]; [server goAway]; [[server connectionForProxy] free]; } switch (fork()) { case 0: break; case -1: [[Console new] logf:"Couldn't fork...exiting."]; printf("Couldn't fork...exiting.\n"); [logger free]; [[Console new] free]; exit(4); break; default: [[Console new] logf:"parent exiting."]; exit(0); /* parent goes away quietly */ break; } // tty, stdio stuff server = [NXConnection registerRoot:logger withName:defaultName]; if (!server) { [[Console new] logf:"Can't register \"%s\" with name \"%s\"?", [logger name], defaultName]; [logger free]; } [server run]; // proper freeing stuff } Thanks, peter -- I felt his rocket science training was inadequate. peter@tahiti.umhc.umn.edu (Peter Eisch)

Apple has included samples >& documentation on their developer CD, so I assume they endorse it. I've not had a chance to look at the Working Software API, but I should clarify at least one thing about how I would envision the API which I'd like to see working: the calling program is responsible for parsing the text and determining things like "is this a word?" "what language is it?" etc. This means that many present-day applications which do not make distinctions between languages will either not be able to do a multilingual document or will need to be extended. The spell checker only needs to worry about tasks like determining if word X is spelled correctly and being able to supply alternate spellings for word X (the latter task should be doable on any word so that I could type in fiend and get suggestions of friend, find and fend as well as an indication that fiend is a valis word. There should be the possibility to do both spell-check the whole document as well as check the current word. Or only one of the two depending on the application at hand.

In the NeXT step reference book it talks about using the autoscroll method to scroll a view when the cursor is dragged to a position outside its superview. It also says you should invoke this method from within a modal responder loop to cause scrolling to continue while the cursor is outside the View's superview. I have implemented the autoscroll without the modal responder loop, but the problem is that scolling isn't continuous while the cursor is outside the View's superview. The view only scrolls each time the mouse is dragged. Can anyone tell me how to implement a modal responder loop. I've looked in the reference book at Application class methods. Some of these methods are used for modal responder loops but there use is not explaned well. Nadi Itani nitani@eecs.wsu.edu

Unfortunately, NeXT has not documented the WindowTemplate class (nor DBModuleTemplate), so you cannot easily implement what you describe. A side effect of this fact is that you cannot write an inspector for your window subclass. I've worked around this annoyance by using another object in conjunction with my window. While this is not the most elegant solution in the world, there's little else I could do without using undocumented classes and methods. I posed the following question to the NeXT engineers present at the NeXTWORLD Expo developer session titled 'Meet the Engineers': "Why is the WindowTemplate class undocumented and do you plan on fixing it?". Jean-Marie Hullot (the primary author of IB) replied that he didn't really know why and didn't seem to think it was too important an issue. <whine on> I agree it's not too big of a problem in the scheme of things, but I have been frustrated several times by the use of undocumented classes in the AppKit and DBKit. I get the impression that other developers have done a bit of headbanging in this department as well. As I've mentioned before, undocumented classes are not inherently evil, but when their use in a kit prevents you from accomplishing reasonable things (such as providing an inspector for a Window subclass), I get a bit peeved. <whine off> > Also, in the content of palettes, does anyone know a way to > programitically create a window that IB can deal with?

You're trying too hard. 8-) Just instantiate a window in IB, change its class to your subclass, and create an outlet to it and its representative view on the palette window (for the sake of this discussion, call these outlets windowOutlet and paletteRepresentation, respectively). Then in your palette's finishInstantiate method, do the following: [self associateObject:windowOutlet type:IBWindowPboardType with:paletteRepresentation]; Cheers, Bob -- Bob_Vadnais@pdh.com (NeXT Mail welcome) PDH Inc., 2635 North First Street Suite 224, San Jose, CA 95134-2034 Voice: (408)428-9596 Fax: (408)428-9599
Newsgroups: comp.sys.next.programmer From: freimer@cs.cornell.edu (Robert Freimer) Subject: Using Allegro Common Lisp 3.1.20 under NeXTSTEP 3.1 Message-ID: <1993Jul20.140859.25540@cs.cornell.edu> Organization: Cornell Univ. CS Dept, Ithaca NY 14853 Date: Tue, 20 Jul 1993 14:08:59 GMT When I upgraded my cube to 3.1, I discovered that ACL no longer worked. I tried rebuilding and received an error that _alloca was undefined. This is caused by the switch from GNU C 1.93 to 2.2.2. alloca() is no longer in the system library and now is an internal function to the C compiler. The fix is to rebuild with the non-shared versions of the 3.0 libraries. The following procedure for fixing a virgin Allegro Common Lisp is modified from a comp.sys.next.programmer article by Bill Vrotney. You should find all of the files mentioned here on your ACL distribution. I refer to the top level directory of this distribution as ACL/ and the build directory ACL/build. For upgrading from a system that worked with 3.0, follow steps 3, 4, and 6. Warning!!! (from Franz Inc.) This procedure results in creating a new ucl.o binary file. You may distribute this method but not the resulting ucl.o file. 1. Install the MusicKit_3.1.pkg available by anonymous ftp from ccrma-ftp.stanford.edu. The Music and DSP libraries are no longer supported by NeXT. This package includes the 3.1 version of libdsp. The other option is to drop -ldsp from the LIBRARIES statement in step 4 below. 2. First look at the byte size of the file ACL/build/ucl.o, if the size is 612364 bytes then skip to step 3. Otherwise look at the file ACL/dumplispPatch. This is a shell archive that will patch ucl.o with the "dump lisp" patch. More precisely cd ACL cp dumplispPatch build cd build /bin/sh dumplispPatch /bin/sh install_patch.sh Now ucl.o should be 612364 bytes long. Tthe original ucl.o will be saved in a file called ucl_orig.o. 3. Create symbolic links from the 3.0 non-shared libraries on CDROM. This saves space on your hard disk, since the libraries should not be needed, except when rebuilding ACL. Another option is to copy the libraries. ln -s /NeXTSTEP_3.0/lib/libsys_p.a /lib/libsys3.0_p.a ln -s /NeXTSTEP_3.0/usr/lib/libNeXT_p.a /usr/lib/libNeXT3.0_p.a 4. Edit the file ACL/build/config. You might want to save the orginal <config file. Replace the following lines LIBRARIES = -lNeXT_s -ldsp_s -lsys_s USYMS = -u libsys_s -u libNeXT_s -u libdsp_s with: LIBRARIES = -lNeXT3.0_p -ldsp -lsys3.0_p USYMS = 5. Edit the new binary file ACL/build/ucl.o in emacs and save the results. Go to ACL/build directory, run emacs and find-file ucl.o replace-string _rld _jld replace-string __bcopy _bcopy^@ save-buffer The ^@ above is the null character (000 byte) and can be entered in emacs using C-q C-<space> and will look in an emacs buffer as a single character ^@ and NOT two characters. 6. Finally reinstall ACL as usual. You do this by going to the ACL/build directory and /bin/sh config 7. The online version of the manual (cl-manual.tar.Z) is available by anonymous ftp from sonata.cc.purdue.edu, under /pub/next/docs. Also grab fi-gnu-clman.tar.Z, which contain the emacs lisp code to index the manual. -- -Robert

While it's true Objective C does not provide language support for private methods, the Objective C runtime allows you to roll your own support quite painlessly if you choose to be fascist about it. 8-) Suppose class Green contains instance methods it does not want to publish to its subclasses. Besides implementing these methods with a category, not announcing their presence in a header file, etc., you can preface each such private method with the following snippet: if (! [self isMemberOf:[Green class]]) [self doesNotRecognize:_cmd]; While you still must ensure that subclasses do not implement methods that will override Green's private ones, this potential pitfall is safely avoided using decent method naming conventions. I believe language support for private methods (and while we're at it, class variables) would be a nicer solution. After all, it's possible to do OO flavored programming with ANSI C and a decent runtime library. One of the nicest things about Objective C is that it cleanly extends C (i.e without mutilating it ala C++) to support inheritance, encapsulating, dynamic binding, etc. ObjC provides the down in the weeds runtime support quite transparently.

Nope, these calls have never worked in NEXTSTEP, and at this point I doubt they ever will. In the past, NeXT has claimed they don't work reliably in SunOS either, which is why they didn't bother.

A lot of driver's such as HD, Tape and Ethernet drivers are very time critical, too much latency and you miss events (such as the next sector) and you introduce a long delay (such as a disk rotation). If you have 'core' drivers in the system which do this your system performance goes out the window. If you're running NeXTSTEP with NFS or AFS (I do) you want 105% performance from your network driver. Yes, this kit sounds really good for all those strange devices like scanners, digital cameras etc that people need to hook up but I think we're going to suffer from 'hacked-up' drivers for a while to come.

This is not a bug in NeXTSTEP. It is a bug in Draw. It has probably always been there, but it has just now shown itself. There is nothing wrong with getNextEvent (at least, not in this context :-)). The reason that you see the postscript errors at the call to getNextEvent is because that is when messages (including error messages) are received from the WindowServer. The PS error actually occured sometime earlier. The bug is the following. In that modal event loop, a drawSelf:: message is sent with an uninitialized rectangle. Most of the time, the uninitialized rect has innocuous values, and nothing bad happens. However, on occassion, some bad values get in the rect (whatever was on the stack) and a bunch of NaNs get sent to the Windowserver in a call to PScomposite(). The WindowServer doesn't take too kindly to that. I did the following, and it seemed to fix it for me. I changed the declaration of that rect to the following in Polygon.m (at line #110) : - (BOOL)create:(NXEvent *)event in:view { float *pptr; ---> NXRect r = {.0,.0,.0,.0}; NXRect viewBounds; NXPoint start, last, p; Hopefuly, this will fix things for you.

Message-ID: <1993Jul20.172934.18132@adobe.com> Sender: usenet@adobe.com (USENET NEWS) Organization: Adobe Systems Incorporated References: <22cg1gINNpqn@frigate.doc.ic.ac.uk> Date: Tue, 20 Jul 1993 17:29:34 GMT NS/FIP display drivers are all subclasses of IODisplay. Any display card that supports a framebuffer as a contiguous region of randomly accessible memory (i.e. not a small window on a larger framebuffer) can be supported by subclassing IOFrameBufferDisplay (which is a subclass of IODisplay). As mentioned in previous messages, you need only override a few methods in IOFrameBufferDisplay to implement a new class. SVGA style cards (such as ET4000 and Cirrus based boards) are not implemented as subclasses of IOFrameBufferDisplay. To write drivers for this type of card you need to subclass a not-yet-public class. When this class is made available, writing these drivers will not be much more difficult than those mentioned above (no need to play with page fault handling to do bank switching as has been suggested). Note that in the current architecture the WindowServer does most of the work, and much of the work of the device driver is handled generically by superclasses. That's why NeXT advised an earlier poster: > "Third-party developers should not try to subclass the IODisplay > class directly and should only subclass the IOFrameBufferDisplay > class. A new class to provide possibilities for writing segmented VGA > drivers might be in 3.2" One last note, 8 bit color is not currently supported. This means that while you can use SVGA cards in 1024x768x8 mode, it can only be as grayscale (which by the way looks quite nice given a decent DAC). Joe Pasqua

Palettes are great for designing interfaces and doing awesome "Test Interface" demos to wow friends and families. However, a palette object won't help you stamp these dudes onto the screen programatically. I suggest two approaches: 1) Make a "stamp" object which will stamp these widgets onto the screen for you. 2) Create a subclass of box which has the appropriate items inside itself and then stamp these box subclasses all over the place. These two notions involve about the same work: programmatically instantiating (can you say that 10 times fast?) a bunch of items, and then adding them as subviews of some view. The exact implementation depends on how you want to abstract this "stamping" process. -- David J.

Even if compiling one program under NS 3.n seems to work, there's no guarantee that will still be true under NS 3.{n+1}. Compiler options like -bsd and -posix don't merely define preprocessor macros--they can have radical effects on which headers are searched, which libraries are used, etc. It's almost as if you were compiling on completely different systems.

Well, I don't know about 3.1, but I have a working version for 3.0. It seems this question has come up fairly frequently lately, so here is what helped me. At least the binary I got this way unpacks my files correctly. So read on at Your own risk. in files Controller.h and DefaultHandler.m: replace #import <appkit/defaults.h> by #import <defaults/defaults.h> in file Controller.m delete the following 3 lines _after_ '@implementation Controller' #include <ctype.h> extern int access(), free(), system(); extern char *malloc(), *getenv(); and insert the following _before_ '@implementation Controller': #include <ctype.h> #import <sys/file.h> #import <stdlib.h> then use make to compile. There still remain a couple of warnings I didn't get rid of, but it works anyway. Of course, if You want gzip support, You will also want to modify Opener.table and Opener.iconheader, but I guess You knew that.

If it doesn't automatically know how to read it, it will try to convert it to a readable format (ascii, rtf, etc) with the available filters. So I basically need to write a decompression filter which returns the decompressed file on the pasteboard as either rtf or ascii. This will allow DL to index compressed files. This should be possible to do without decompressing the actual file being indexed (by decompressing to stdout or something). There is still the issue of how to open the compressed files. How DL does this isn't clear to me yet. If you search the docs and click on one of the returned filenames, will it use a filter to open a decompressed file or will it open the file as is?

Distribution: world Message-ID: <22concINN2js@golden.kaleida.com> It's not that I don't like NeXT's new screen saver with the cube and the hostname, but I miss my floating login panel! So I hacked the loginwindow app and the ScreenSaver.bundle to find out how it all works. It's really very simple and I suspect that in 3.2 it will become a public interface so that people can write screen savers. Actually it would make more sense to adapt BackSpace to provide the screen savers. I guess time will tell what NeXT will do with it. Anyway, to write a screen saver bundle all you have to do is implement a class called ScreenSaver in a bundle that gets installed at /usr/lib/NextStep/loginwindow.app/ScreenSaver.bundle. The ScreenSaver class has to, at least, responds to 2 methods: startScreenSaver and stopScreenSaver. Everything else is up to the ScreenSaver.bundle. The bundle gets loaded dynamically by name and is then sent the start and stop messages at the appropriate times. One tricky thing is that the startScreenSaver message gets sent at regular intervals based on what the TimeToDim default is. That is, if you have a TimeToDim default set to 60 (seconds), your ScreenSaver class will get called EVERY 60 seconds. This just means that you have to manage some state within the ScreenSaver class to tell whether you should really do anything or not in response to this message. That's it. Pretty simple, huh? It really looks like this stuff was only half way implemented when 3.1 shipped. NeXT should do a couple things to make this a usable interface: 1. Use a default to specify what screen saver to load. 2. Use NXBundle's 'primaryClass' method to determine the controlling class, so you can guarantee no class name conflicts 3. Document it! On cs.orst.edu and nova.cc.purdue.edu, I've submitted MovingLoginPanel.compressed. It contains the ScreenSaver.bundle and the source to this simple screen saver. To install it, rename your existing ScreenSaver.bundle to something else and copy the bundle into /usr/lib/NextStep/loginwindow.app. Adjust you TimeToDim default to whatever you want and make sure that you have ScreenSaverEnabled set to YES. You'll have to restart the loginwindow app so log out of the WorkSpace and type exit for the user name, that should do it. Enjoy!

I have browsed through the resulting rows making changes at random. Now how can I do the following? 1. Save just one of the rows back to the database when more than one have been modified. 2. Revert just one of the rows to its original state after more than one have been modified. Analysis: I have some thoughts but no solution. 1. During an ordinary save operation, DBKit iterates through the rows saving each changed one individually. I suspect there is a private method like _saveChangesAt:(int)index. Can someone confirm or refute this from experience? I fully understand the dangers of calling private methods. 2. During the course of a save, DBKit performs a locking query prior to updating the database. Somehow it is able to determine whether there has been another update since the original query. This would seem to imply that the original data is still present somewhere, and might be used to revert the changed record. In truth, I fear that only some sort of checksum is kept around. True? Answers or possible avenues of investigation would be greatly appreciated. -- Ron

Especially to get all the information out of the subchannels. The problem with that is that most CD-ROM drives just do not give you the digital sound data via the SCSI port. Subchannels are beyond dreams. Some very few newer CD-ROM drives are supposed to ignore the "don't copy me digitally" bit in the TOC (table of contents) of most (all?) audio CDs. The only other way is to use some CD player with digital out and an interface for this port to your computer. The interface is called AES-IBU (EBU?). Of course there aren't any subchannel informations there. If you want to know more about CD formats you should consider those colorful books (red book, orange book, etc.). There's a good article (series?) in the German magazine C't about the various CD-ROM formats. It should be less than a year old. Bye, Uli

I force users to either save or discard changes to a modified record before changing to another record using tableView{Will,Did}ChangeSelection:. This prevents confusion over which change failed should a failure occur and avoids the problems you mention. With a well-designed interface, this approach isn't too onerous. I've implemented a simple undo that discards changes and refetches setting the selected row to the previously-selected row. It's not ideal when a large number of records must be refetched, but I found it difficult to make changes to a RecordList's contents without the FetchGroup thinking something had changed even when I was restoring things to their original values. -- Art Isbell Cubic Solutions NeXT Registered Developer NEXTSTEP software development and consulting NeXTmail: isbell@cats.UCSC.EDU Voice: (408)335-1154 USmail: 95018-9442 Fax: (408)335-2515

Message-ID: <22JUL93.15560813@enh.nist.gov> Sender: news@dove.nist.gov Organization: NIST Date: Thu, 22 Jul 1993 20:56:08 GMT I have need to archive a hash table which keys integers to Classes (not objects). Obviously, the Class itself shouldn't be saved to a stream, but it would be very nive if the class would save its name, and then, when asked to unarchive, would return the object given by : objc_getClass(). The problem here (if it wasn't obvious before), is that I am not entirely sure how the Object class goes about its -read and -write methods. From looking at the inards of an archived file, it would seem that object first writes its class name. When reading, it reads the class name, uses the function mentioned above, alloc's that's object, and sends it a -read: message. So the question is: Can I do anything about implementing +read: and +write: methods (perhaps in a category of the object class), that would do nothing except return the class... I have a feeling that I would have to actually create my own NXWriteClass((NXStream *)aStream, (Class) aClass)), and NXReadClass functions to do this... and oh, it just becomes a mess.. In the meantime I have created an object that is capable of hashing integers to Classes, and archives them.... but it is such a rig that I thought I would try to do it correctly. Any suggestions?

I have an application that has (lets say) two objects. Object 1 implements: - setX:(float) x Y:(float) y in:aCoordSystem { printf("X=%f, Y=%f, CoordSystemObject = %p\n", x, y, aCoordSystem); return self; } Object 2 implements: - aMethod { [myObject1 setX:5.0 Y:6.76 in:nil]; . . return self; } Seems straightforward? Nope. The variables are not getting sent correctly. My x and y float values are wierd (x is always 0, and y is between 2.125... and 3.589...., depending on what x is sent to it). Further, the aCoordSystem varibale has a value!! 0x80000000 which is certainly not nil. To confuse things even more: I created a tiny app to test my object (which is a little more robust than shown above). I still got the errors with the passing of x and y, but the id was passing correctly. So I changed the methods from accepting floats, to accepting float pointers. Then everything worked fine. I am working on both black and white hardware, and the error is consistent. I am thinking that maybe some of the optimization code is screwing things up, but I don't know how to do a make without the optimization on... Does anyone have any suggestions?

From DevTools/09_Debugger/_DebuggingCoreFiles.rtf: NeXT has extended GDB to allow debugging of NeXT core files, which are in the Mach-O file format. These files are very large, so they aren't generated by default. In order for core files to be generated, you must raise your core file limit by typing one of the following commands at the UNIX prompt: unlimit core limit core 5m The first command allows core files of any size to be created. The second command only allows core files less than 5 megabytes to be created. The maximum core file size is up to you. Note that because of the way core files are created under Mach, even a small application can create a core file of several megabytes. Core files are generated in the /cores directory, if it exists; otherwise, they're generated in the current working directory. -- Gregory H.

Basically, we've got a panel with a popUpList on it. The popUpList controls which view is visible in the swapView- like an inspector. We want to be able to print each view when the panel is printed, rather than just the one visible. To do this, in the panel's getRect:forPage: method we swap a new panel in for each page. This mostly works fine. But there's a problem. In a test print of nine views, some of the middle pages exhibited some strange behavior. One page had printed normally, except there were some text fields from the next page printed "on top" of what shoulf have been there. Another page was normal, but had a browser from the next page printed on top of it. In each case, whatever was printed wrongly on on page appeared in its proper place on its own page, also. This is similar to what I have seen if there is a [fooView display]; inside of the getRect:forPage: or in any methods called from inside it. The page being printed is overwritten with the image from the following page. It seems that my problem is being causd by a display of the offending parts, but our code doesn't do that anywhere. Another strange element is that if printing the whole bunch, the same pages are messed up. But if we print a smaller range which contains those pages, the pages are fine. Has anybody experienced this? Does anyone have an idea about what's going on? -- Jon Hendry I'm not a real programmer, <jon@afs.com> But I play one on co-op.

I want to know if there is a way to modify the object's code so that I can load up a nib with the original classes, and save them out as the new classes.

Message-ID: <1993Jul23.015128.8497@pixar.com> Sender: news@pixar.com (Usenet Newsmaster) Organization: Pixar -- Point Richmond, California Date: Fri, 23 Jul 1993 01:51:28 GMT I'm about to hack something together, and thought I'd toss the idea out here first to see if anybody has any good feedback: Well, I've been playing with all the various 3D apps available under NEXTSTEP, as well as writing my own stuff, and I'm finally sick of it. I know the 3DKit folks are probably busy with other (more important) things, so I thought I'd bring my gripe to the Net. a few caveats: if you don't know what a shader is, read the doc before posting a question (with regard to this particular thread I want to start). I'd rather we kept this particular discussion at a high S/N ratio. so, take a deep breath, put on your 3D cap, and let's go: One way to think about RenderMan shaders is that they're similar to typefaces or colors. They actually have attributes more of Multiple Master Adobe fonts, where you have a given set of parameters that you frob. From a NEXTSTEP programmer point of view, the shader-as-font-or-color analogy holds in many ways, with one glaring exception: we've got a FontPanel and a NXColorPanel, but no ShaderPanel. As random folks have pointed out over the years, the FontPanel is less than ideal, since it doesn't allow you to have your own groups of fonts (i.e. it enforces the Font family hierarchy on you) or give you any sort of shelf to put commonly used fonts. I believe there is some 3rd party app which does this better, but I've never seen it. You really want things like FontWells FontSwatches and such. I think Mesa has something like this. The NXColorPanel, on the other hand, is a much more completely implemented thang. You can make named lists of colors, keep color chips around, save out your named list of colors, etc. Any NeXTSTEP app which uses color (pretty much all of them, right?) uses the NXColorPanel. This makes it persistent over applications, and "It just works." On the 3D side of things, however, things are nowhere near as developed. All the 3D apps I use on a semi-regular basis (3DReality, FrontFace, Intuitiv'3d, my own weird stuff) all have their own solution to this problem. They all handle it basically the same (incompatible) way: they scan some known locations for all the .slo files, and present the user with a list of shader names. They also look in various places for a tiff file which corresponds to that shader. Some of the apps help the user make this image, some just specify a known location to stick an image of the correct size with a given name. None of them do it the same way. I've got well over a hundred shaders. Now, I know, I know, I'm weird, but remember when you only had 10 typefaces? Now how many do you have? It won't be that long, especially if NSI takes off in universities this fall, before you have tons of shaders too. Right now, it takes a *long* time for each of these apps to scan the various places to get the info it needs about all these shaders. Sometimes, I want to see all my shaders, but most of the time, I would rather group them and have it read info about a given group (the same way I can do for colors on the NXColorPanel). I also want to have these lists of shaders be persistent across apps. As we get more 3D apps on NEXTSTEP, and as more apps start including 3D capabilities, this problem will become more acute. The next problem is that when you write a shader, you tend to write it in a very general way. Sometimes, too generally. Also, sometimes you get a commercial shader (i.e. from the Valis Group), and it's great, but it's got too many parameters. In other words, you want to be able to associate an arbitrary interface with a given .slo file, so you can strictly control which parameters of the underlying shader are frobbable. PIXAR sells a product on the MAC and PC which does exactly this: it's called Glimpse. Under NEXTSTEP, you could imagine making a NIB file which gets loaded in which only allows certain parameters to be manipulated in certain ways (i.e. constrain floating point values, give you an intuitive interface to specifying some vector, constraining color choice to some known set, etc.) So here's what I'm gonna do: for my system (WavesWorld) I'll be writing a couple of objects: WWShaderPanel, WWShaderList, WWShaderWell, and WWShaderInspector. The WWShaderPanel will look like what you see when you bring up the colors panel and click on the Pantone button. You will have a popup list of WWShaderLists at the top, and a ScrollView showing the shaders in the currently selected WWShaderList. You'll be able to add and delete shaders from a given WWShaderList, and read in and write out WWShaderLists. (now comes some handwaving, this is what I'd like some feedback on) When you double click on a given shader, it instances a N3DShader and inits it from that slo file. It also loads in nib file stored in some canonical place (like ~/Library/Shaders/English.lproj) with a canonical name (xxx.nib where xxx.slo is the shader file). This nib file will be owned by a WWShaderInspector, and it will mediate between the user and the particular instance of the shader. (end handwaving) The WWShaderPanel will have a matrix of NXShaderSwatches, which will allow thumbnails of a given shader instance be able to be dropped into a WWShaderWell, the same way you can drop a color into a NXColorWell. Also, clicking on the edge of the WWShaderWell should bring up the WWShaderPanel, of which there is always only one instance. Anyway, I'm going to be implementing this stuff sometime in the next month or so (hopefully), and if anyone has any brainstorms, let me know. As long as I get the code finished before I'm back at the Media Lab, I'll probably make it available, so it's in your best interest to advise early and often... -- --> Michael B.

The application is working well, but I am a bit obsessive about performance and I want to make sure I've done everything right. I had a look at the Concepts/Performance/Checklist.rtf that came with NeXTStep 3.0, but that just confused me: 1) Under the heading `Window Server Memory Usage' there is an item that says, ``No windows with alpha channel on screen (check with Winfo app''. I can't find anything like Winfo.app anywhere on my machine or on sonata.cc.purdue.edu or cs.orst.edu. How do I check to ensure that none of my applications windows, views, NXImages, etc. have had alpha creep into them? 2) Under the heading ``Images'' there is an item that says, ``Don't composite with NX_COPY, use NX_SOVER (doesn't allocate alpha channel)''. This seems exactly backwards to me. It also contradicts the ``Compositing'' section in the Concepts/Performance/ ImprovingDrawingPerformance.rtf section of the on-line documentation.

How do I >add it so that every FirstResponder in every nib I ever create >automatically gets a showInfoPanel: method? I discovered a file in /NextDeveloper/Apps/InterfaceBuilder.app called firstResponder.table. It is a list of all the method names that appear in gray in the FirstResponder class inspector in IB. If you add method names to that list, they appear in new nibs just like the regular defaults. This solution isn't optimal, however, because any upgrade that includes a new IB could potentially blow away the changes unless the installer is aware of them. At my site the installer is always me, so either I'll remember or I'll have no one to blame but myself :-), but at sites where the owner of the machine is not the person responsible for doing upgrades it could be a problem. Another way is to create a header file called FirstResponder.h in the project directory and parse that file in IB every time you create a new nib. The problem with that is that if you forget to include any of the original methods from firstResponder.table the usual firstResponder connections may be messed up. The following script creates a good header file and insures that all the default methods are included: #!/bin/csh cat <<ENDHEADER #import <objc/Object.h> @interface FirstResponder:Object { } ENDHEADER (cat /NextDeveloper/Apps/InterfaceBuilder.app/firstResponder.table; \ cat ~/Developer/Data/firstResponderExtraMethods.table) | \ sed -e 's/\"/\- /' -e 's/\"/sender/' -e 's/\/.*//' | sort echo @end Note that output is to stdout. I call this script 'mfr' (make first responder) and keep it in ~/Unix/bin. My file 'firstResponderExtraMethods.table' uses the same format as firstResponder.table in the IB app wrapper. It contains this: /* Additional First Responder Actions */ "showInfoPanel:"; "showPreferencesPanel:"; Of course, any action methods can be included. The script is also not an optimal solution because you have to remember to create the header for each new project, and you have to remember to parse the header for every new nib. If anyone has a more automatic way to do this, I'd appreciate hearing about it. Thanx, Michael -- Michael Pizolato gnihtyreve noitseuq michael_pizolato@afs.com NeXTMail appreciated

Winfo is an application in the MiniExamples. The MiniExamples seems to have appeared on ftp.next.com as part of NeXTAnswers so take a look there. Winfo is kind of a neat application. What it does is show you a miniture picture of your DPS environment, all the windows on or off screen. For each window it tells you its size, depth, etc. > 2) Under the heading ``Images'' there is an item that says, ``Don't > composite with NX_COPY, use NX_SOVER (doesn't allocate alpha > channel)''. This seems exactly backwards to me. It also > contradicts the ``Compositing'' section in the Concepts/Performance/ > ImprovingDrawingPerformance.rtf section of the on-line > documentation. The problem with using COPY is that it copies all the bits of the source image into the destination. That means that if your source image has alpha you have copied the alpha on the screen. Alpha on the screen doesn't do you any good. It is only used in compositing operations, so copying it to the screen just promotes the depth of your window unnecessarily and wastes memory. Using SOVER causes a compositing operation to occur. It is like taking your source as a sheet of plastic (transparency) where your source is at least semi-clear you will see the destination, where your source is opaque you will only see source. Once the operation is completed the alpha will be gone from the destination. The alpha is only used to calculate what the destination should look like. So, what you want to do most of the time is to keep all the alpha off your screen. That saves memory. When you need to use alpha you create an NXImage and you put the alpha image in there. That window will be deep, because it has alpha, but is hopefully short lived or small so it doesn't waste much memory. Then you want to overlay a transparent object over some part of a window on the screen. At that point you composite the NXImage using SOVER.

I think this problem is harder than it first appears.... Try sending your Text object a firstTextBlock message. The NXTextBlock structure is defined in <appkit/Text.h>. That structure *looks* like it has line break information. You would have to go through that to count line spacings and insert page breaks and page numbers (etc.) where appropriate. Cheers, Joseph

Apparently this is a problem that is not isolated... A summary: The problem came from the fact that I was attempting to pass floats in my method call. My application is very large, and sometimes the headers do not load for the correct .m files (programmer error here). Because the compiler did not know what my method definition really was, it made an educated guess and decided it would default to double's.

Well that sounded useful (especially collecting core files in /cores) so I just tried it and got "unlimit: command not found". I'm using bash and it appears that limit/unlimit are built in to csh. From reading the manual page, it looks as though these limits only apply to processes inherited from the csh you give the command to. We need them to apply to applications launched from WM. Has the behaviour with regard to core files changed between 2.x and 3.0? I used to get core files often under 2.x but haven't seen many (if any) since upgrading. Dave Griffiths

I think they're part of the gcc run time library. I want to implement forward:: in such a way that it calls the method function (obtained with methodFor:) directly. This requires somehow setting up the stack frame from the method argument frame. (I'm actually trying to implement the class swizzling trick suggested by someone a while back to detect which methods an object calls. The problem with switching isa in forward:: and then calling [self performv::] is that it only works the first time - any subsequent methods called by that method will reach their true destination).

Each bundle provides a set of related screens (35 bundles). We have a single menu provided by the main bundle, which means that from anywhere the same menu is provided and any screen can be called up. We wish to attach help to UI objects, but are having some problems - it seems that: "Just as with help links, an NXHelpPanel searches both the application's file package and the appropriate file in /usr/lib/NeXTSTEP/Resources/language.lproj in attempting to find the file associated with a particular user-interface object." This seems to imply that only the main bundles help is searched for the help on a UI object, and not so called 'supplement' (i.e. help loaded with bundles) directories. If we put the help for a UI object in the main bundle's help, then we cannot associate it with a UI object from another bundle. Are we doing something wrong (I hope so) or is this a limitation? Any comments would be much appreciated. ADVthanksANCE. David Boyle.

In Mach, pages of a file are cached on demand by page faults. Pages remain in memory even after they become unreferenced, and are released when memory becomes scarce. Filemem provides a way to determine which parts of a file are being used. For example, filemem can be used to help scatter-load a file by showing which parts of an executable image are in memory after a certain operation. After deter- mining which pages are resident in memory, the program pageSymbols(1) can be used to show the symbols residing on that particular page of a file. The output of filemem is a list of logical page numbers, starting from page zero at the beginning of the file. The page size is the same as the machine-independent page size of the system.

What we need is a forum for people to talk specificaly about the music formats out there and exchange as much information as possible about them, in order to help everyone write better music editor and player programs!

It looks like that it vanished.

Also it is me unable to find a proper magic sequence or vt100 emulation in a new version of Terminal is terminally broken?

When the mouse enters any of the icons, my mouseEntered: event returns the correct trackingTag. But things get weird when I try to connect two icons with a line. When my mouse first enters an icon, I get the correct tag for it, then I start drawing a line from inside of the icon, and the mouse exits the icon and goes towards another one when drawing a line, (HERE IS THE TRICK) but when the mouse enters that icon, my mouseEntered: event returns the same tag as the first icon, and the coord system remains the same of the first icon's coord system. Each icon is a subview of the content view of the workspace window. Does anyone out there have any experience in tracking rectangles? How can I always get the correct trackingTag? Your help is greatly appreciated... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -Ye yhe1@cc.swarthmore.edu he@carnegie.swarthmore.edu (NeXT mail welcome)
Newsgroups: comp.sys.next.programmer From: wave@pixar.com (Michael B. Johnson) Subject: more shader discussion Message-ID: <1993Jul26.064709.7112@pixar.com> Sender: news@pixar.com (Usenet Newsmaster) Organization: Pixar -- Point Richmond, California Date: Mon, 26 Jul 1993 06:47:09 GMT Well, my previous post about wanting widespread support for some interapplication agreement about how a shader would represented to the user sparked some intelligent mail to me about how a few people felt, but it also pointed up something which perhaps I didn't adequately explain in my post. I briefly mentioned the notion that I felt it was important to be able to attach arbitrary interfaces to a given shader. Several people have pointed out that once you initialize a N3DShader from a given .slo file, you can get at the arguments by asking the object, and therefore you can automatically build up an interface to the shader. Yes, yes, I know you can do that, and that's certainly a nice fall-back to have. But it was exactly that which made me post in the first place... Let's look at two examples: a commercial shader you've bought (i.e. you don't have source code to) and a shader you've written. Why wouldn't this first order interface (i.e. present the user with color wells for colors, sliders for floats, type-ins for strings, etc.) be good enough? Take the first case: the commercial shader. Let's say you just bought a set of shaders from the Valis group. One in particular, "Striped Wallpaper", you plan to use it for a project in which you're designing the interior of a set of offices. You'd like to let others in your workgroup frob about with the rooms you've designed, but you'd like to restrict their color choices to some preselected palette. When showing it to the client, perhaps you'd like to allow them a slider or set of radio buttons with prices on there, and have the shaders parameters be updated accordingly (i.e. this combination is more expensive than that - it's a non-standard color, etc.). Let's say you're writing a shader and you'd like to sell it. Let's say you've written a shader which does wood (a pretty canonical shader to write). To add value to your shader, you'd like to offer a wide range of interfaces to the shader. One of someone designing cabinets, one for people designing desks, etc. You'd also like to offer interfaces which map types of wood (oak, pine, walnut, etc.) to specific combinations of shader parameters that would be difficult for the user to find on their own. Pragmatically, what does this mean? If I sell/give you a shader called foo.slo, it might come with a script that would install into your ~/Library/Shaders directory the following: ln -s foo.slo fooBar1.slo cp English.lproj/fooBar1.nib in ~/Library/Shaders ln -s foo.slo fooBar2.slo cp English.lproj/fooBar2.nib in ~/Library/Shaders ln -s foo.slo fooBar3.slo cp English.lproj/fooBar3.nib in ~/Library/Shaders I might also have translated the info in these nibs and have other language specific nibs installed. They're all really pointing to the same shader file - they just have different ways of presenting it to the user. Clearly, what we want is some API that allows a developer to build a NIB file for a shader, and have that NIB file get loaded in when someone wants to see the shader. Only as a last resort should the user be confronted with the sliders and type-ins they see today in all the NEXTSTEP 3D offerings. Don't get me wrong: no other platform has such widespread understanding and access to RenderMan as NeXTSTEP, but we can do so much better... There's a wonderful market opportunity here (value added resellers to shaders) if we can just get this figured out. The handwavey part of this is figuring out a way that this can be done *just* by building a NIB. In other words, the file Owner of the nib has to be smart enough that the NIB builder just has to identify the type of the file owner and control-drag away. The problem is that I have a solution to this problem, but it involves a bit of hair that not everybody might want to buy into and I'm wondering if anybody has a better idea.

Message-ID: <1993Jul26.125903.1235@beech.mcs.gvsu.edu> Sender: news@beech.mcs.gvsu.edu Organization: Grand Valley State University, Allendale MI Date: Mon, 26 Jul 1993 12:59:03 GMT Hello: I am trying to use one ScrollView and switch between more than one Text object as it's docView. The problem is that the ScrollView isn't automatically scrolling like it should when the text goes past the bottom of the clipView. The catch is that it /does/ work with it's original text object, just not after I setDocView: to a new text object. The new text objects are reflecting any updates that I make to them, but I can't get the ScrollView to reflect those changes. Here's what I'm doing: appText = [[Text alloc] initFrame:&contentFrame]; [ . . . ] [appText setVertResizable:YES]; [mainScroller setDocView:appText]; [mainScroller setVertScrollerRequired:YES]; [ . . . ] length = [[mainScroller docView] textLength]; [[mainScroller docView] setSel:length :length]; [[mainScroller docView] replaceSel:message]; [[mainScroller docView] scrollSelToVisible]; [mainScroller reflectScroll:[[mainScroller docView] superview]]; [mainScroller display]; And after doing this, nothing happens. I can watch the text get added to the text object in the ScrollView until it gets to the bottom, at which it keeps adding but not scrolling automatically. The scroll bar doesn't even pop up, unless I force it to by resized the window with the mouse. What I don't understand is that the exact same code (in fact, without even the reflectScroll: message) works fine if I use the text object that was originally in the ScrollView. So, in other words, the "stock" ScrollView works fine with it's original docView, but as soon as I change via setDocView: it ceases to work. Is there something really blatant that I'm missing? I'll really happy if it's something simple that I don't see. The only thing that I could think of is that I'm breaking some sort of delegation chain between the ScrollView, it's clipView and it's docView; but I've tried to manually create a new clipView and recreate the whole thing - with no luck. Any clues greatly appreciated! - Jim wissner@beech.mcs.gvsu.edu

First off, QuickBase is more of a database engine than a database program. By that I mean it's more of a programmer's resource than something that average users might use for building databases. It usually gets discussed in comp.sys.next.programmer instead of the software newsgroup. QuickBase lets the programmer use a relational database via a few different interfaces. You can either use some objects (in the programming sense) which understand SQL commands, or you can use the DBKit interface, or I think there might be some other options there too. One nice thing about this is that you can write both NeXTSTEP applications for your database, or regular command-line interfaces to the same database (which is nice if people telnet into your machine to access the information). I've only used QuickBase on a few fairly simple databases so far, but it certainly looks like you could build complicated databases using it. I even have some more elaborate databases that I want to build using QuickBase, but one of my NeXTstations is on loan to someone else, and that's thrown a wrench in a number of my plans. Right now I don't have Quickbase on any of my machines (I was out of hard disk space for awhile...). I've done some work with 4th Dimension on the Mac, and it really seems to me that the combination of QuickBase on the NeXT along with the Interface Builder would be a superior set of tools for creating small or medium-sized custom databases. For a large database, you'd probably want something running on a larger and faster machine than a NeXT anyway (QuickBase has the database itself on a NeXT, you aren't hooking up to some database server on a non-NeXTSTEP platform). If you're looking for more information on QuickBase, you could send a message to sdc@gun.com to get in touch with someone at SofDesign Solutions (note: there's no "t" in SofDesign...). You can also send a message to sdc_demo@gun.com to get a demo version of QuickBase. I believe this demo version is for NeXTstations only, but SofDesign was planning to have an NS-Intel version of QuickBase available soon (via a different email address). If you send to the demo account, you'll get nine messages mailed back to you (seven of which are NeXTmail). Be sure your message has a valid return email address, as it's an automatic daemon sending the messages, which only looks at the return address (nothing reads the text of the message you send it). Disclaimer time: I've done some beta testing for QuickBase, but I'm not part of the company. The guy who started the company is an RPI student who I used to be aquaintances with (which is how I got to be a beta tester). If you pick up the demo, you'll probably see my name pop up in one of the demo applications (I just took an older demo and spruced it up a bit). -- Garance Alistair Drosehn = gad@eclipse.its.rpi.edu ITS Systems Programmer (handles NeXT-type mail) Rensselaer Polytechnic Institute; Troy NY USA

I still like having Opener around, simply because: 1) it includes all kinds of compressers/decompressors with it (even though most of them are rarely needed in practice). 2) you get an icon in the fileviewer for any type of file that opener can decompress. Thus, you select a file, and if it has a special icon then you know you can just double-click on it. I think both of these are worthwhile reasons to have opener around, particularly if you're in an environment with a lot of "non-unix" users. NeXT went with a double-click interface for opening files, and I think that should apply for archives of files as much as anything else.

This calls objc_msgSend which requires that isa points to the correct class. But I've switched the isa variable to a mole class in order to detect the messages that object is sent, so I wanted to generate a call to the method function directly. It's easy to get the address of the function, all that's missing is the way to set up the stack frame. I'm not bothered about architecture independence, it's just a hack to save time when trying to work out what other methods are invoked by appkit class methods. I got hold of a copy of the gcc runtime to see if I could use some of it's routines and discovered that it's different from that used by NeXT - even the class structure. Why is this? The nature of Objective C means that the runtime has a much higher profile than in other languages as programmers exploit dynamic binding in any way they can - traversing the structures themselves - so there may be a portability issue when the language becomes more widely used. Because NeXT donated their changes to gcc to GNU, I expected such basic things as objc_msgSend to be the same. Dave Griffiths

I have several custom view classes that are to be instantiated (by dragging from a palette), connected and configured (using an inspector) in Interface Builder. For the resulting nib file to be loaded into the application I first need to link the custom views' object code into my application. This is done by loading a bundle. Both, the bundle and the palette, are generated in the same project directory by a simple addition to the palette's makefile in Makefile.postamble: APP_OFILES = $(CLASSES:.m=.o) $(APP_CLASSES:.m=.o) bundle: $(BUNDLE_DIR) $(APP_OFILES) ld -r -o $(BUNDLE_DIR)/$(NAME) $(APP_OFILES) APP_CLASSES contains classes that are not linked into the palette because they are not needed there. It is even possible to split each custom view class into two parts: One that needs to run in Interface Builder only for configuration and another that does the real work in the application. The latter is put into a category that is not linked into the palette but only into the bundle by including it in APP_OFILES. Hope this helps. Any other ideas?

I ended up using + finishloading methods in the various palette views to setup a CustomView capable of dynamically linking from a known location (/LocalDeveloper/Bundles). Since the CustomView loading code doesn't reference any particular class, it might be possible to collapse all the common + finishloadings into common code; but I haven't figured that out yet. The NXBundles could be named explicitly too. For the application, I just used objc_setClassHandler to intercept the error message, and bring in the missing class(es). It still suprises me there isn't a `right', advertised way to handle missing class objects. It seems like NeXT should have system-wide object vendor, implemented with distributed objects. And, if not, at least have a way to start system services by dropping them in place (ones that run without the workspace).

We tried also to build a HDF-file WM inspector which recognizes HDF files and can give some information about the content of the file (for example the number of data points). In order to get this information out of the HDF file routines are needed which are stored in a library on /usr/local/lib. But upto now we didn't succeed in connecting this library to the HDF inspector. We have tried to connect the inspector.bundle to the libraries by making a Makefile.preamble which includes the needed libraries (we did the same thing in our NEXTSTEP applications, and for the applications it worked). The inspector is build according to the steps given in the reference GeneralRef/19_WorkspaceManager/IntroWorkspace.rtf. This inspector works if there are no calls to routines stored in a user made library. Does anybody know how we can solve this problem? Thanks in advance!!!

Yes. It's an ugly hack, and makes Project Builder give warnings, but what you do is create a Makefile.postamble that has some thing in it based on what you called the project. For example (a BackSpace module), set Project Build to have attributes of project type as "Bundle" and Name as "PlanetView.BackO", you need a Makefile.postamble that has: --- cut here --- # # Makefile.postamble # PRODUCT_ROOT = $(BUNDLE_DIR:.BackO.bproj=.BackModule) INSTALLDIR = ~/Library/BackSpaceViews OTHER_GARBAGE = $(PRODUCT_ROOT) --- cut here --- The PRODUCT_ROOT line is an extension replacement command. Normally this is "PRODUCT_ROOT = $(BUNDLE_DIR:.bproj=.bundle)" (which is where the .bundle comes from). *Fortunately*, you can post-override this (the last definition is taken, and the bundle.make in 3.0 at least doesn't check for it already being defined). As another example, if project name is "Foo.Bar", and you want the bundle to end up with the ".Joe" extension, you would have PRODUCT_ROOT = $(BUNDLE_DIR:.Bar.bproj=.Joe) (The INSTALLDIR definitions allows me to have BackSpace modules that I can do a "make install" on and have everything work...) -- Scott Byer NeXTMail: byer@mv.us.adobe.com Adobe Systems Incorporated These are *my* opinions, and 1585 Charleston Road, P.O.

A program to convert between text files for Unix, DOS, and Macintosh, converting the end-of-line characters as necessary. 2. A program to take a uuencoded .tar.Z file (NeXTmail received not in Mail.app) and produce a directory with the desired attachments inside. Here are the solutions I received. All three apps are available on the archives: 1. Rosetta.app is the hands-down winner! Why did I not already know about it? 2. Two approaches here. (a) MailService will do the job very nicely. If you have the NeXTmail message, uunencoded, in a file or in a Terminal window, simply select the entire message and invoke the service Services/Mail/Send As A Message. The original message will now be sent to you and you can receive it properly in NeXTmail. (b) Opener.app can do the job without using NeXTmail, if that is needed, but you have to do a couple of edits yourself. Nevertheless, it is as simple at 1-2-3: 1. Edit the Begin 666 line so that the internal file name is something like: msg.tar.Z (the line will read: Begin 666 msg.tar.Z) 2. Change the name of the file to something like: file.uu 3. Double-click on file.uu and Opener should do the entire job. You will get: - an O_file directory with msg.tar.Z in it. - an O_msg directory with a file index.rtf, which contains the (possibly rich) text of the message itself, plus all of the attached files and directories.

I find this ok however, I'm a little concerned that IB is practically dictacting the way I design my app from a class perspective. For instance I cannot play with the UI without ensuring that all the target/action methods line up after my changes. This I believe is a fundamental design problem using NeXT's conventions for applications with multiple nibs. And i've seen this mentioned as a critism of IB in the past. I know that one can write target/action methods that do simply nothing but forward themselves onto other classes and this is probably a solution but what do people generally do to avoid IB taking control of your app's design. Has anybody come up with a scheme that lets you chop and change at will with the UI. I hope this generates plenty of worthwhile discussion on this topic.

That's a joke! I'm kinda confused how to achive the following DBTableView behaviour. Firstly, my sub-model looks like this PROJECT-CONTACT PROJECT project_id project_id contact_id project_desc PROJECT-LOCATION project_id loc_id to_project (dbmodel to get the project_desc) I currently have a DBTableView in which I display project information for a given location. Hence the to_project relationship so that I can get the project's description field for any one location. My database has the following 1> select * from projects 2> go project_id project_desc ----------- -------------------------------------------------- 1 project 1 2 project 2 3 project 3 (3 rows affected) 1> select * from project_location 2> go project_id location_id ----------- ----------- 1 1 2 1 3 2 (3 rows affected) 1> select * from project_contact 2> go project_id contact_id ----------- ----------- (0 rows affected) Currently for location 1 the DBTableView mentioned above looks like project_desc project 1 project 2 I have set up the dbmodel this way so that I may apply the qualifier based on location. I assume this is the correct way about doing things. Now, not only would I like to see the projects for any particular location but I would like to tag each as having been completed by the current contact. Hence I need to create another column and derive information from the project_contacts table in order to indicate wether or not this particular contact has completed this project. I also have to be able to mark a project completed by the current contact too so it's very like BooleanFormatter execept that I do not know how I should go about deriving the "indicator" columns data.

Having overcome that problem of not having a putenv(), and being unable to find setenv()/unsetenv().... I have sendmail 8.5 compiling! (under NeXT 3.1) There were very few changes that needed to be made. sendmail 8.5 ships with Makefile.XXXXX where XXXXX is the machine, and I needed to modify the Makefile.dist to perform for the NeXT, which I saved as Makefile.NeXT. I needed to add a couple of headers, and for the life of me I couldn't get a header included that actually defined pid_t. So I just typedef'd it in an #ifdef __NeXT__ . It compiles without a complaint. Now, off to the sendmail.cf stage..... Aaaak! OK, sendmail 8.5 ships with a macro language, that is similar to IDA. You write a small file that explains the differences between the standard behaviour and the wanted behaviour run it through m4 or Berkeley Make. Ping! Problem! The m4 that Next is shipping is too old, and apparently NeXT isn't shipping Berkeley Make, its some other make.. So, while I have the good fortune of having access to an SCO UNIX machine that is running a suitable m4, and I can get my sendmail.mc into a sendmail.cf file, that doesn't do the rest of us much good. Where can I get source for the current Berkeley Make? Apparently the m4 support for GNU m4 is not going to be around forever, and this seems like the better way to go.

I find this ok however, I'm a little concerned that IB is practically dictacting the way I design my app from a class perspective. For instance I cannot play with the UI without ensuring that all the target/action methods line up after my changes. This I believe is a fundamental design problem using NeXT's conventions for applications with multiple nibs. And i've seen this mentioned as a critism of IB in the past. I know that one can write target/action methods that do simply nothing but forward themselves onto other classes and this is probably a solution but what do people generally do to avoid IB taking control of your app's design. Has anybody come up with a scheme that lets you chop and change at will with the UI. I hope this generates plenty of worthwhile discussion on this topic. -- Real programmers don't use Email they communicate with people.

As it exists in NiftyMatrix.m, the cell being dragged is constrained to stay within the bounds of the matrix. What I'm trying to do is allow dragging outside the matrix (the idea is to allow dragging a cell from one browser to another). Below is the relevant part of the mouseDown: method as implemented in NiftyMatrix.m /* * move the active cell */ mouseLocation = event->location ; [self convertPoint:&mouseLocation fromView:nil] ; cellFrame.origin.y = mouseLocation.y - dy ; /* * constrain the cell's location to our bounds */ if (NX_Y (&cellFrame) < NX_X (&bounds)) cellFrame.origin.y = NX_X (&bounds) ; else if (NX_MAXY (&cellFrame) > NX_MAXY (&bounds)) cellFrame.origin.y = NX_HEIGHT (&bounds) - NX_HEIGHT (&cellFrame) ; [ code to handle possible scrolling if we're located in in a ScrollView deleted for clarity ] /* * composite the active cell's image on top of ourself */ PScomposite (0.0, 0.0, NX_WIDTH (&cellFrame), NX_HEIGHT (&cellFrame), [cellCache gState], NX_X (&cellFrame), NX_Y (&cellFrame) + NX_HEIGHT (&cellFrame), NX_COPY) ; However, if I remove the code which constrains the frame of the dragging cell to the bounds of the matrix, what happens on the screen when the mouse moves outside the matrix is that the cell moves *underneath* the scrollView, rather than *ontop* of the matrix and possibly out of the window altogether. Since I know very little about DPS and what PSComposite is actually doing, can someone help explain this behavior and how I can correct it? Could it have something to do with the graphics state of the cell? Could it have something to do with the fact that the matrix is a subview of the ClipView of the ScrollView?

Suppose I have a class like the following: @interface Foo : Object { struct _sFlags { unsigned int flag1:1 ; unsigned int flag2:1 ; unsigned int flag3:1 ; } sFlags ; } In the read: and write: methods which archive this object, how do I specify the type of the bitfields in the arguments to NXReadType() et al.? The documentation (NS 2.1) says that the type encoding for structs should be of the form {<type>...} but does not say what the `type' code for a bitfield is. In the `Concepts' chapter on Objc, the @encode() directive is mentioned. There is says that a structure with bitfields is specified as {bnbn...} where n=number of bits. It also mentions that some of the values returned by @encode() are *not* valid for typed streams (tho it doesn't explicitly mention `b'). However, when I try giving this to NXReadType() it reports an error and refuses to do it. The only work-around I've been able to find is to note that sizeof (sFlags) = sizeof (short) and to archive the structure as {s} Is this going to cause me unexpected problems up the line? Considering the number of classes in the AppKit which use structs with bitfields like this, there has got to be a more ``pollically correct'' way to do this. Any and all help greatly appreciated. -- Paul Biron (310) 825-5614 | Outside of a dog, a book is man's best friend pbiron@gslis.ucla.edu | Inside of a dog, it's too dark to read GSLIS, UCLA | ---Groucho Marx What's another word for ``thesaurus''? ---Stephen Wright

Since Michael B. Johnson is beta tester of intuitiv'3d, we at Cub'x are quite disappointed to see he forgot to mention those intuitiv'3d features... Anyway, it would be a good idea to share shader objects for all 3D applications. However I think that it should be the work of NeXT and not a third party (even as freeware). This could indeed be a N3DShader evolution since: - N3DShader has no icons - N3DShader does not support tiff for texture mapping. - N3DShader does not support map calculation for environment mapping - N3DShader does not include displacement bounds for displacement mapping intuitiv'3d does not store tiff separately for shader's icons, but stores the icon with the instance that stands for the shader instance... An icon can be set inside the software using the IconPanel. The icon can be a tiff somewhere on your disk or a picture rendered inside intuitiv'3d. intuitiv'3d also handles mathematical functions with a FonctionPanel and FunctionWell...

If you find that the tool is defining how your apps are going together, don't use it! You can create everything with plain source code that the IB can do. It will take a lot moer (more, sorry) time (like about 500 times more), but there are definitely situations where the IB should NOT be used. In fact, many of my interfaces make extensive use of the customView because I like to set up borwsers, etc... my way, not IB's way. Using the custom view allows me to position things in the windows, though, and that saves a lot of trial and error coding to see if the window is set up the way I want to. If you have a radial arm saw, and you are trying to turn a table leg, it is better to go out and buy (or make) a lathe. You could do the work with the saw, but it won't be nearly as nice! Kevin

The storage of bitfields within an int is at the discretion of the compiler and may be architecture dependent. The Intel porting guide suggests that bitfields be archived as individual (char)s: - write:(NXTypedStream *)stream { char temp1 = sFlags.flag1, temp2 = sFlags.flag2, temp3 = sFlags.flag3; [super write:stream]; NXWriteTypes(stream, "ccc", &temp1, &temp2, &temp3); return self; } - read:(NXTypedStream *)stream { char temp1 = sFlags.flag1, temp2 = sFlags.flag2, temp3 = sFlags.flag3; [super read:stream]; NXReadTypes(stream, "ccc", &temp1, &temp2, &temp3); sFlags.flag1 = temp1, sFlags.flag2 = temp2, sFlags.flag3 = temp3; return self; } BTW, you need the temp variables because there is no such thing as the "address" of a bitfield. -- Gregory H.

I'm not sure exactly what you're referring to here -- do you mean that in IB you can't target objects in one nib from those in another? If so, you may want to consider connecting to IB's First Responder psuedo-object.

The plan I've heard is to do the primary inheritance ala ObjC, and have id's in the primary object point to other objects that define the alternate inheritances. Cool. To get the object to recognize alternate inheritance methods, one overrides the doesNotRecognize: method the primary to check if the alternate objects recognize the selector. All well and good, but before I cut over the heart of my engine to it, I'm concerned about the performance impacts! This concern brings two questions to the net: QUESTION 1: For some Black (or White) processor, what are the minimum/typical/maximum times (in microseconds) for resolving a selector if it a) is, and b) is not in the selector cache. For the latter, I suspect one could assume that the requisite symbol tables are mapped in VM and resident there, which they probably would with frequent references. Reasonable assumption? QUESTION 2: Is there some (possibly unpulbished) interface which would let my program install an object into the selector cache. A remove or flush would also be good. What would it take to cobbel or beg one in? Allen P.S.: Unfortunately, unlike many of you, my circumstances are such that I can only read the net every weekend (or two), so email'ing me on responses that you think I should respond to quicker would help.

The following is a description of what I do: First, as you suggest, I indeed create a class as the NIB's owner-- I call such a class the NIB manager. Second, I usually limit the number of windows to one per NIB. Also, the NIB manager is always a delegate of the window in that NIB. Third, I implement the action method that is appropriate for a particular window (or, I should say, that is an appropriate action when that particular window is key) within the NIB manager for the NIB that contains the window. And last, I connect the First Responder as the target of all (well, "most") action messages, and let the First Responder chain take care of dispatching the method to the appropriate NIB manager (via the window delegation mechanism). If you use the First Responder chain to dispatch the action methods, you effectively divorce the target/action stuff from the specific organization of the classes and views in the app. Two more points: 1. If you have studied the MVC (Model-View-Controller) paradigm first proposed many years ago (and implemented extensively in most Smalltalk implementations), you will recognize my NIB manager as being the 'C' of MVC, and the window in the NIB as being the 'V'. If appropriate, I might create a separate 'M' class, or else implement the 'M' functionality within the 'C' class (the NIB manager). 2. The NIB manager (via window delegate methods) can easily turn on and off applicable target/action buttons (such as menu cells of the main menu) that are applicable when the window that the NIB manages becomes key. See the documentation for the methods (I think) '- windowDidBecomeKey' and '- windowDidResignKey' (or 'windowDidResignFirstResponder', or something like that-- I'm not in front of my NeXT right now). Nevin P.S. I hope I was understandable. I'm getting lazy and didn't want to type any more (explanations) than necessary.

Wonder why they allow categories to override, and > unreliably at that? Seems like a counter-intuitive thing. It's not really surprising, once you realize what categories really do. A category is, basically, a nice wrapper for adding a new set of methods to the linked list of method sets that are part of a class definition. That is, there is a (struct objc_method_list *), which is named isa->methods inside method definitions. struct objc_method_list { struct objc_method_list *method_next; int method_count; struct objc_method { SEL method_name; char *method_types; IMP method_imp; } method_list[1]; /* variable length structure */ Note that this structure represents a node in a linked list. A category defines an objc_method_list with all the methods in that category, and the runtime system inserts that at the start of the linked list isa->methods. So why is it guaranteed that if you load only one category, you will override the methods in the class definition (which is really just the main category)? The class (along with the main category) must be created before the category may be added to that class. Only once that is done can the methods in the category be added to the class. So since the main category got there first, the new category takes precedence. (The astute reader will observe that the runtime system could have been constructed in such a way that the main category might not have been added until later. Thus, a new category could be added before the main category, giving the main category precedence. But since it *is* guaranteed that one category definition will take precedence over the main category, I just assume the runtime system always puts in the main category when it creates the class.) And the reason why it's not guaranteed which category will get precedence when there's more than one is that it's random (as far as the programmer is concerned, anyway) which category gets loaded and processed by the runtime system first. NeXT doesn't document this as being true, but I imagine it's 100% guaranteed that methods in a category that get dynamically loaded will get precedence over anything loaded before. But again, if you dynamically loaded two categories simultaneously, it's random which category would have precedence. ...jkd -- jdawson@oceania.com (John Dawson) If you define cowardice as running away at the first sign of danger, screaming and tripping and begging for mercy, then yes, Mister Brave

Date: 29 Jul 1993 01:12:32 -0500 Organization: UTexas Mail-to-News Gateway Sender: daemon@cs.utexas.edu Message-ID: <9307290522.AA08041@seawolf.next.com> Hello, Great news for all NEXTSTEP Developers and Programmers interested in the following NEXTSTEP source code examples for NEXTSTEP 3.x: NETINFOKIT MINIEXAMPLES APPKIT MINIEXAMPLES INDEXINGKIT MINIEXAMPLES DATABASEKIT MINIEXAMPLES Conrad Geiger NeXT _________________________________________________________________ Anonymous ftp for the NEXTSTEP example code is now available via archive server: ftp.next.com. The MiniExamples for APPKIT, DATABASEKIT, INDEXINGKIT and NETINFOKIT are located in: /pub/NeXTanswers/Documents/Software_&_Tools/MiniExamples Each folder contains an ascii README file describing all available examples. Here is the master list: [ This ReadMe file describes the MiniExamples available in the AppKit, DatabaseKit, IndexingKit and NetInfoKit directories. Each MiniExample is stored as a separate ".compressed" file. The MiniExamples are only available via anonymous ftp or email (and only if you can receive NeXTmail). Since ".compressed" is a binary format, remember to switch to binary mode (type "bin" at command line) when fetching via ftp.] APPKIT MINIEXAMPLES AtYourService example (NEXTSTEP 3.x Release compliant) This example illustrates how applications can export "Services" to other applications (they will appear in other applications' Services menu). BananaSplit example (NEXTSTEP 3.x Release compliant) A simple NXSplitView sizing example. CellScrollView example (NEXTSTEP 3.x Release compliant) A simple example that installs a matrix of custom cells in a subclass of ScrollView. This forms a basis for a user interface that allows the user to add and delete objects from a list. ConvertXYtoChar example (NEXTSTEP 3.x Release compliant) How to convert from an X,Y coordinate location in the Text object to the nearest character position in that object. Grabber example (NEXTSTEP 3.x Release compliant) How to create a TIFF image by reading the bits from a rectangular region from the screen. NormalBrowser example (NEXTSTEP 3.x Release compliant) A very simple straightforward example of an NXBrowser object. PaginationLab example (NEXTSTEP 3.x Release compliant) An example of breaking up a large view into pages for printing. ScrollViewDeluxe palette (NEXTSTEP 3.x Release compliant) An enhanced subclass of ScrollView which includes support for adding controls to the scrollers, automatic support for rulers and support for synchronizing other views. StringList palette (NEXTSTEP 3.x Release compliant) Two objects used for generating and maintaining lists of strings and filenames: StringList includes methods for adding, inserting, sorting and searching strings as well as built-in browser support so that it can be a browser delegate. FilenameList is a subclass of StringList that specializes in filenames. Both objects can be initialized inside of InterfaceBuilder. TextORama example (NEXTSTEP 3.x Release compliant) How to create a TextField which supports restricting text length, autojumping to another TextField and interpreting a carriage return literally. This example also illustrates how to implement emacs key binding support for the Text object. ThumbWheel palette (NEXTSTEP 3.x Release compliant) The ThumbWheel object includes the functionality of a Slider plus the features you would expect from a real thumbwheel. TIFFandEPS example (NEXTSTEP 3.x Release compliant) How to open TIFF or EPS images, how to convert from one format to the other, and how to save them out. TTools palette (NEXTSTEP 3.x Release compliant) This example is an advanced IB Palette primer. Demonstrated features include: how to write a custom connection inspector and custom connector objects; how to palettize Matrix without restricting its prototype cell class; how to add a library target to your palette project so that applications can link in the palette code. WhatsUpDoc example (NEXTSTEP 3.x Release compliant) A skeletal example of how you might manage multiple documents in an application. Save, SaveAs, SaveTo, SaveAll and Revert are implemented. Winfo example (NEXTSTEP 3.x Release compliant) Winfo provides information about NEXTSTEP window memory usage. It's useful for finding windows which unnecessarily allocate alpha or color planes and waste large amounts of memory. ZooView application (NEXTSTEP 3.x Release compliant) An example of a horizontal SplitView. DATABASEKIT MINIEXAMPLES AddressBook example In order to run this example, you need to have a SYBASE server with a pubs database installed. [The pubs database is a sample database provided with the SYBASE limited server package.] After you are properly connected to the Sybase server, you can perform operations such as Select, Insert, Update or Delete. AssociationExample example The current version of DBKit does not provide a way to filter the records fetched by a detail FetchGroup. DBKit does not allow a qualifier to be built into a relationship, nor does it allow a qualifier to be permanently attached to a FetchGroup. The Association example provides a way to do filtering of detail records by using a subclass of DBAssociation that replaces the default association which exists between the master FetchGroup and the detail FetchGroup. BarChart palette This palette demonstrates how to use your custom UI objects with the DBKit. It illustrates in particular the DBCustomAssociation protocol which allows you to retrieve or set values to your database via a custom view objects. BooleanFormatter example This example shows how to substitute the default display format in the TableView to your own format by subclassing the DBFormatter class. In order to run this example you need to have an ORACLE server with a demo database installed. DateFormatter example This example shows how to create a formatter for a DBTableView that uses a subclass of TextFieldCell to validate the user's input. The formatter forces the user to type in values of the form xx/xx/xx. In order to run this example, you need to have an adaptor, a model and a data source. DocumentPalette palette (3.1 only) This palette is a subclass of Control. It shows how to conveniently store files into the database using their absolute pathnames, instead of the data associated with them, and let the WorkSpace do the work for opening or reading the files. You can also drop a file into the document well, and double-click to open it for reading. OrderByTest example This example shows you how to change the sort order every time the columns in the tableview are rearranged. In order to run this example, you need to have an ORACLE server with a demo database installed. RadioAssociation source code These two files allow you to make a matrix of radio buttons sychronize with the boolean data type of your database. TableView example This example shows how you can define a DBTableView and a DBModule programmatically instead of using the corresponding IB objects. It also shows how you can change the sort order every time the columns in the tableview are rearranged. INDEXINGKIT MINIEXAMPLES LanguageReader/ReaderDomain example (3.1 only) This simple program shows how to generate a .domain file programmatically. You should also read the SimpleReader MiniExample (in LanguageReader, below) which shows how to build a customized reader by subclassing IXLanguageReader. LanguageReader/SimpleReader example (3.1 only) This example shows how to build a customized language reader. The reader is organized as a bundle, so that it can be dynamically loaded by the Indexing Kit, if you are using NEXTSTEP applications such as Digital Librarian. RecordManager example (3.1 only) This example demonstrates usage of the Indexing Kit at the IXRecordManager level. At start-up, a new database .data will be created in your home directory. You can then enter records into that database which is managed by IXRecordManager and performs searches based on the record attributes. NETINFOKIT MINIEXAMPLES NILoginPanelTest example This example shows how to bring up a login panel, and do password authentication. The example uses specifically the NetInfoKit classes NILoginPanel and NIDomain.

From: robert@steffi.demon.co.uk (Robert Nicholson) Newsgroups: comp.sys.next.programmer Subject: DBKit DBTableView, DBExpression question Date: 26 Jul 1993 21:48:37 +0100 Organization: me organized? That's a joke! Distribution: world Message-ID: <231fv5$10r@steffi.demon.co.uk> I'm kinda confused how to achive the following DBTableView behaviour. Firstly, my sub-model looks like this PROJECT-CONTACT PROJECT project_id project_id contact_id project_desc PROJECT-LOCATION project_id loc_id to_project (dbmodel to get the project_desc) I currently have a DBTableView in which I display project information for a given location. Hence the to_project relationship so that I can get the project's description field for any one location. My database has the following 1> select * from projects 2> go project_id project_desc ----------- -------------------------------------------------- 1 project 1 2 project 2 3 project 3 (3 rows affected) 1> select * from project_location 2> go project_id location_id ----------- ----------- 1 1 2 1 3 2 (3 rows affected) 1> select * from project_contact 2> go project_id contact_id ----------- ----------- (0 rows affected) Currently for location 1 the DBTableView mentioned above looks like project_desc project 1 project 2 I have set up the dbmodel this way so that I may apply the qualifier based on location. I assume this is the correct way about doing things. Now, not only would I like to see the projects for any particular location but I would like to tag each as having been completed by the current contact. Hence I need to create another column and derive information from the project_contacts table in order to indicate wether or not this particular contact has completed this project. I also have to be able to mark a project completed by the current contact too so it's very like BooleanFormatter execept that I do not know how I should go about deriving the "indicator" columns data. Any clues? So rather than qualify the projects for just a particular contact I need to see all of the projects at that same location but also some indication as to which projects this contact has been working on and an ability to toggle existing projects and show that this contact is working on more projects. -- Real programmers don't use Email they communicate with people.

References: <23752d$28c@cnn.sim.es.com> Date: Thu, 29 Jul 1993 12:53:53 GMT Right, well I tried it and as far as I can tell it basically gives you an approach that as you say divorces the target/action connection from the specific UI element and places it onto the first responder and eventually is forwarded by the window's delegate. I like this however, can you please give me a tangible explaination as to why this is such a desirable approach? Incidently, have you updated your Rules.rtf lately? (Send me a copy :-)) ie. why go indirectly thru first responder to file owner rather than directly to file owner. My original question related to having the ability to come up with a scheme that didn't tie a particular action method down to a specific window which your scheme still does. Hence, you can play with the UI but really only in the same window if you get what I'm saying? Since you are still dependent on the file's owner. ie the windows delegate right..... I know what I'm looking for is perhaps a bit unrealistic but imagine automatically being able to take a UI based on one window only to just be able to split it up into mulitplewindows just by using IB. Your approach is certainly a step in the right direction though.

My own concern was that this should really be a more generally available thing, so that I could share shader instances between full blown 3d apps, like intuitiv'3d, solidThinking, FrontFace, 3DReality, etc. and other apps that aren't exclusively 3D, things like a spreadsheet that does 3d charting. It seems silly to have to fire up intuitiv'3d, render lots of little pics as representative of my shaders, and have it save them away somewhere where I can't use them in FrontFace, 3DReality, or my own apps. Also, I didn't want to mention intuitiv'3d's (yikes! look at that punctuation) specific features, as I thought that was breaking my beta test agreement. I didn't see anything in my post (I mention intuitiv'3d as one of the apps I'm using, vaguely mention that they handle it in a nice-but-incompatible-with-other-apps way) that violated my agreement. And, truthfully, a lot of this comes originally from being a beta tester of PIXAR's Glimpse, which I've had in my hands as a beta tester longer rather than Intuitiv'3d.

At last year's NeXTWORLD Expo Steve Jobs demoed a cool encryption app that was supposed to be built into NS 3.0, using the padlock as a status indicator. It promised to make file encrytion as simple as printing or any other service, but alas, the technology was a little too sophisticated for the US Gov't to allow. Also, it was based on a proprietary (and superior) encryption technique, rather than the more popular RSA method (who are, ironically, located in Redwood City.) Unfortunately, Apple may have the first fully-integrated encryption system, built into their AOCE environment, slated for release later this year. One more case where NeXT pioneers an idea, with the best implementation (too good in this case), yet someone else will probably get all the credit. (Earlier issues of NeXTWORLD, around Jan-Apr 1992, have articles describing NeXT's encryption technology.) -- Don __________________________________________________________________________ I neither confirm nor deny the presence of any disclaimer at this juncture

Date: Fri, 30 Jul 1993 00:44:09 GMT I would like to know how NeXT's release of Mach handles the delivery of UNIX signals in the context of a multithreaded program. According to the CMU paper on Mach, a multithreaded task signal is received by an ARBITRARY thread. It is not possible to pre-determine which thread will receive the signal. OSF/1 Release 1.1 changed this to allow the first thread, i.e the thread that executes main() within a C program, to be the receiver of 'asynchronous' signals (SIGINT for example). A class of 'synchronous' signals (SIGSEGV, SIGEMT, etc...) are delivered to the thread that caused the signal to be generated. Does NeXT's Mach behave like OSF/1? From my tests it would appear so, but this could just be a fluke. Thanks in advance.

If I loop in "-interruptOccured" and don't enable interrupts until my device says its finished will other "like" devices fail to have their driver notified. 2) If I "-enableInterrupt:" in "-interruptOccurred" while looping and receive another interrupt, will the kernel message "-interrupOccurred" from another thread (simultanesously) or wait to the initial method exits. 3) Does handlePacket:error: take a full ethernet packet or does it require that the source and destination etheraddress to be stripped prior. -- Doug Boyce dwboyce@acsu.buffalo.edu

First off, the compositing operation is happening inside the lockFocus on the matrix's view (which is the scrollview's docView). Therefore, although you are calling PScomposite with numbers outside the bounds, the clipping rectangle is still in effect (the one the scrollView sets up to do the scrolling). The correct way to approach this (in my opinion), is: If you need the nifty capabilities, use a different keyboard modifier to switch over to a drag operation. Drag operations are supported in NEXTSTEP through a number of protocols. It works through pasteboard types, so you'll have to set up a pasteboard type that represents the data you wish to move between views. My recommendation is to type 'NXDragging' in Librarian with the NeXT Developer icon selected, and searching set to 'within'. This will give you the documents necessary to do what you want.

You don't show the surrounding code, but I think the problem is either that you don't have a valid object in your "selectedList" id or else "typedStream" hasn't been opened or initialized properly. Do other things archive correctly to the same stream? What happens if you stop the app in the debugger and look at "selectedList"?

Do as NeXT says, not as they do!!! converting a bitfield to the "real" type (u_char, BOOL,...) before archive will mean you never touch the archiving code again (for porting reasons). And, hey.

On the other hand, I would like to use the NeXT supplied gdb with its 'view' feature. Guess what, it doesn't work (for me). When typing 'view' Edit.app won't show me the source file. When I load it by hand and then try to, say, use the 'Break at' button gdb will say something like: type name unknown at symtab pos 64. Error occured processing command from Edit. So may be there is a general incompatibilty between gcc-2.4.5 and gdb? If I give up using 'view' and simply type 'list' at the gdb prompt it tells me ... type name unknown at symtab pos 64. Same thing as before! How can I debug that program on my NeXT? Will I be able to use the 'view' feature? Thanks in advance for any help. Dirk. P.S.: I couldn't run and try it with cc++ as the supplied cc++ didn't compile my program.

It's not difficult so much as time consuming. Yes, it helps if you've written something like GameKit's PreferencesBrain, but otherwise each time you add a new preference there's a lot of little things to tie together. It's sufficiently painful to make you want to write PreferencesBrain and to make me wonder about the possibility of designing IB inspectors for subclasses of certain appkit objects to handle defaults themselves. Such an inspector could let you specify the name under which the value should be stored in the defaults database, the real default value etc (the value would only be held inside the object itself). Talking of dwrites, what do people think of the alternative of using archiving to record the applications state? I've got a situation where my program needs to save an ordered list of filters each of which is in a bundle and each of which need to record some state information (eg enabled/disabled). Using dwrites appears awkward. Keeping bundles and archive info in step similarly so. I seem to want a bundle that maintains state info or an archive that contains loadable objects! Dave Griffiths

One thing that I did early on in beta 3.0 days was design a abstract superclass (with corresponding IB inspector) that was able to load in nib files upon awakening. Making a palette of subclasses of this class allowed me to build complete apps inside of IB, because I could design the interface for each object in a separate (set of) nib(s). This means that when I go into test interface mode, these various nibs get loaded in by the various objects, and I can play with my completed app from inside of IB. Given a complete and flexible enough set of objects (which, in my case I've written and palettized), I've found the various paradigms that IB allows for app development to be quite flexible, actually. -- --> Michael B.

Under the readType: data: length: method, I would have to pass an address of the id I want to write to, and the length using sizeof().... However, what I wind up doing is, in the first method, I send my object's id, along with the length of an (id), and in the seconf method, I pass the address of the id, with the length...

We're curious about who would want this sucker--does it have a market? we ponder. This is a tool that graphically describes methods, tools, and interrelationships beyond the capabilities of Interface Builder. As designed, it will embody a unique version control system specially designed for modularity of NS projects. Of course this is a tall order for a product that hasn't progressed beyond its first prototype, but we're thinking big. Thinking big pays off, however, when big thinking and big results can go hand in hand; so I'm testing the waters for the temperature of demand for this uncoded product. Drop me some email if you think we're on the right track or if you think this is just a waste of time.

Link the required functions from the maths library into the application, so that they are available when the bundle is loaded. Do this by creating a file named "Makefile.preamble".

In retrospect the installation is simple--if you do all the right things along the way. To install both gcc-2.4.5 and libg++-2.4 on a NeXT machine, without making any mistakes along the way, required approximately 4 to 5 hours of real time, nonstop. Below are my personal **detailed** notes on the install. I hope that they can be of help to someone. I appologize if the detail of the notes insults anyone. However, when I started out, due to my lack of background, I would have liked to have such a set of notes to follow. It would be really nice if someone put together the gcc-2.4.5 and libg++-2.4 into a NeXT Installer package. Tom Bahder email and NeXT mail: bahder@tbb.arl.army.mil Applied Physics Branch U. S.

If you wish to test the compiler by compiling it with itself one more time, install any other necessary GNU tools (such as GAS or the GNU linker) in the `stage2' subdirectory as you did in the `stage1' subdirectory, then do this: make stage2 make CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O" This is called making the stage 3 compiler. Aside from the `-B' option, the compiler options should be the same as when you made the stage 2 compiler. But the `LANGUAGES' option need not be the same. The command shown above builds compilers for all the supported languages; if you don't want them all, you can specify the languages to build by typing the argument `LANGUAGES="LIST"', as described above. Then compare the latest object files with the stage 2 object files--they ought to be identical, unless they contain time stamps. You can compare the files, disregarding the time stamps if any, like this: make compare This will mention any object files that differ between stage 2 and stage 3. Any difference, no matter how innocuous, indicates that the stage 2 compiler has compiled GNU CC incorrectly, and is therefore a potentially serious bug which you should investigate and report. I get the following result (difference) doing the compare on tbb: fox> fox> make compare for file in *.o; do \ tail +16c $file > tmp-foo1; \ tail +16c stage2/$file > tmp-foo2 2>/dev/null \ && (cmp tmp-foo1 tmp-foo2 || echo $file differs); \ done rm -f tmp-foo* fox> 9. Install the compiler. First, su to root, then the actual commands I used was: make install CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O" 10. Install Objective-C compiler, using the command: make install-libobjc CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O" 11. You must now do an installation of the library libg++. (GNU instruction 15.) If you're going to use C++, it's likely that you need to also install the libg++ distribution. It should be available from the same place where you got the GNU C distribution. Just as GNU C does not distribute a C runtime library, it also does not include a C++ run-time library. All I/O functionality, special class libraries, etc., are available in the libg++ distribution. ============================================================================= INSTALLATION of lig++-2.4 ============================================================================= 1. Unpack the distribution software, like gcc was unpacked. First rename the file gunzip libg++-2.4.tar.gz to gunzip libg++-2.4.tar.z. Then uncompress using: tbb> gunzip libg++-2.4.tar.z tbb> tbb> tar xf libg++-2.4.tar tbb> 2. cd libg++-2.4 3. Configure the Makefile for next, use: configure m68k-next-mach 4. Make the following changes in source code: Changes made in order to successfully compile libg++ 2.4 ---- in libg++-2.4/libg++/iostream/procbuf.C comment out //#define _POSIX_SOURCE ---- 5. Do the make using: make all >& libg++.install.log & 6. Now, su to root, and type 'make install' g++ and libg++ are ready to use.

The fileserver from which the application is loaded to any given host may not even retain a compatible architecture. The load may be from a net-mounted read-only directory -- (no way to hash usages on the server) -- and stand-alone copies may be simultaneously loaded from an alternate load directory, and/or across symbolic links. This is especially hard, when software is installed on a server which cannot run the application! In addition, mach messaging channels, IP channels, and the like may extend beyond, or not reach all targets for instances of the .app to communicate with others, or network delays may prevent efficient launch, if (i.e.) udp polls are sent out PLUS the individual user may or may not have access to such ports. It is generally possible to restrict usage by user login, but this breaks when the same user may have a different home directory when logged in on different network-pool machines, or shared general logins among a variety of users. Probably the only reasonable answer is a check-in daemon process running on a designated machine. App launches would not activate until a valid check-in is obtained, and would check-out when terminating (presuming no machine crashes prevented the check-out). The check-in could identify the ``unique host-id'', machine name and user ID. Finger services could be accessed by the daemon to see if the user is still logged in, and if so, a failure to respond by the instance of the .app could be used as a sign that the app ceased without checkout. All of this, however is time consuming for a good interactive GUI application. Bruce Gingery bruce@TotSysSoft.com Total System Software the makers of DFax for NEXTSTEP

These classes are sufficiently complex >that they require diagrams to explain their inner workings. Verbal >descriptions are not enough, I want to see pictures. For a classic example of a method that is difficult to override in a subclass, here is the documentation for "- tile" in NXBrowser: tile - tile Arranges the various subviews of NXBrowserPScrollers, columns, titles, and so onPwithout redrawing. Your code shouldn't send this message. It's invoked any time the appearance of the NXBrowser changes; for example, when scroll Buttons or scroll bars are set, a column is added, and so on. Override this method if your code changes the appearance of the NXBrowser (for example, if you draw your own titles above columns). Returns self. OK, great. This method is obviously going to call a load of other mainly private methods whose function is unknown. Perhaps it's possible to glean something from the instance variables? Here they are: @interface NXBrowser : Control { id target; id delegate; id _reserved1[3]; SEL action; SEL doubleAction; id matrixClass; id cellPrototype; NXSize _reserved2; short _reserved4[4]; unsigned short pathSeparator; char _reserved3[6]; void *_private; } And this highlights another problem. The interesting information about the layout is all held in private variables! Designing a class in such a way that it's functionality can be modified in subclasses is a tricky business. Even if you're the person who writes both class and subclass! It becomes iterative, and you go back to the superclass and maybe split some method in two so that one of them can be overridden. To do anything serious in an NXBrowser subclass without much more information is practically impossible. Dave Griffiths

No. Wish there was! The way you want Edit to work is interesting. It sounds like the way that vi or emacs is invoked from within trn for example. This highlights a difference between the GUI/NeXTSTEP philosophy and that of Unix. When you invoke vi, it's for a one-off (in theory) edit and the parent (usually) waits for it to finish. This instantiation bears no relation to any other copies of vi that may be running. But with Edit, you switch over completely into the Edit environment and get presented with all the other documents that Edit has open. Sometimes this can be annoying, for instance when you're in the WM File Viewer and you just want to take a quick look at a file before returning to the WM. It sounds as though there is a need for this alternative method of invocation (without rolling your own editor with the Text object). Anyone got any suggestions as to how it might be achieved?

It seems Well, talk to PIXAR. They announced, some months ago, that they were coming out with exactly that. I forget the name, but it had a nice ring to it (Yeah, I know, that helps out a _lot_! 8^)). What they propose is to give shaders the same kind of encapsulation as Poscript fonts, so that they are totally exchangeable. The current "standard" is probably too wide-opened for true exchageability to occur. Of course, apps will have to implement this new standard.

It concerns using the [Storage write:] method to write a typed stream to disk. In my program, transactionList is an instance of Storage containing a number of structs that I'm using to keep track of records. I'd like to save transactionList to disk in order to be able to read it in later. I think that I've followed all of the directions I've seen, including those in Garfinkel/Mahoney, but the following code consistently gives me a "Typed streams library error: expecting a writing stream" error and dies. The code is as follows: fd = open (filename, O_WRONLY | O_CREAT | O_TRUNC, 0666); if (fd < 0) { NXRunAlertPanel (0, "Cannot save file: %s", 0, 0, 0, strerror(errno)); return nil; } theStream = NXOpenFile (fd, NX_WRITEONLY); if (theStream == NULL) { NXRunAlertPanel (0, "Cannot save file: %s", 0, 0, 0, strerror(errno)); return nil; } [transactionList write:theStream]; NXClose(theStream); close(fd); and produces the error when I call [transactionList write:theStream]. I know that I'm a bit confused by the various operations that one can do with typed streams, and so it's quite possible that I've used the wrong one.

I use this combination all the time, and with very little difficulty. There ARE problems, but whether you will run into them or not depends on how advanced use of gdb you make and your code (I guess). I would also add that I have many fewer problems with gdb-4.7 and gcc-2.4.5 than I had under NS 3.0 using gcc-2.* and gdb 3.9* (which shipped with 3.0). So things are getting better. I would actually consider gdb-4.7 a strong reason to upgrade to NS 3.1. -- Magnus Nordborg magnus@fisher.stanford.edu (NeXT mail preferred) Department of Biological Sciences Stanford University Stanford, CA 94305-5020 +1 (415) 723-4952 (office)

I'm using a MediaVision ProAudio Spectrum 16, with stereo input jack. Only the left channel appears to be stored using Sound.app. Is this a question of support at the hardware level, or software level? I know the sound object does have 'channel' stuff dotted around in it, and the machine seems quite capable of replaying already digitized stereo sound. Any hints, tip, or anybody aware of stuff around that can record stereo for an Intel box? Cheers, Brian Leake.

That is to say, if I post two identical NX_APPDEFINED type events using DPSPostEvent() will both be picked up on subsequent calls to -getNextEvent? To clarify: 1. Somewhere in the program, [NXApp getNextEvent:NX_APPDEFINEDMASK]; 2. Before an App-Defined event is received, I have a second identical statement -- this is possible because I am using the Subprocess object, so the parent calls -getNextEvent: and so does the child through delegation to the parent. 3. The app now expects two App-Defined events. When I DPSPostEvent an NX_APPDEFINED event, which call to -getNextEvent: will pick it up first?

Like I say in the README, it's not great oop, or particularly well written- I just hacked it out in a week for class. But it does work. It's got lots of buttons and sliders - it's sort of a 3DKit Busy Box. All the source is there, so you can see what I did. Hopefully, someone will learn from it. There's lots of room for experimentation, and it's heavily commented (the class was a history class, with a non-programming professor.)

I reported this yacc and lex bug to NeXT during 3.1 PR1. I think I fixed it by radical surgery to basicrules.make. But this was stretching my understanding of Makefiles, so my confidence level is not as high as I would like. Unfortunately, a fix didn't make it into 3.1.

RCS doesn't handle binary files at all. Get CVS--it's public-domain and runs on top of RCS, and it handles binaries. Another advantage of CVS over plain RCS is that when someone checks out a file from RCS, it's locked and no one else can work on changes to that file until it's checked in again. With CVS, everybody checks out their own copy of the file and commits changes at will--CVS does some pretty smart diff-ing to minimize conflicts. When conflicts do occur it shows you where so you can at least resolve them manually with your favorite editor. CVS still has some shortcomings when it comes to nibs, which can (for the most part) be worked around with some additional steps. We've found that the newfound ease with which we can do multi-person single-project development is well worth the additional hassle for nibs! CVS is available from prep.ai.mit.edu in /pub/cvs. Be sure to get FAQ.gz while you're in there, too.

Date: Tue, 3 Aug 1993 17:06:48 GMT Hello All, Does anyone else think this is a viable suggestion for the Matrix object, or am I just griping because I have to write more code than I wanted to... I am writing a quick little SpreadSheet object and I decided to subclass the Matrix object since it already contains methods for adding rows and columns. The drawback of the Matrix object is that all cells must be the same size. It is relatively straight forward to subclass the Matrix object and add the ability to let the cells be different sizes (at least different row heights and different column widths). I am storing the row heights and column widths easy enough, and I would have been done already if it wasn't for the way that the Matrix determines and uses the cell frame sizes when it comes to: drawing, hilighting, tracking, and cursorRects. The Matrix object has a method: - getCellFrame:(NXRect *)theRect at:(int)row:(int)col for which I thought, Great!, all I essentially have to do is override this method and pass in the correct NXRect for each cell and things will just work. Well, it turns out that when the cells get the method: - highlight:(const NXRect *)cellFrame inView:controlView lit:(BOOL)flag the Matrix method getCellFrame:at:: is called and sent to each cell, so highlighting works automatically, however, the Cell methods: -------------------------------------------------------------- - drawSelf:(const NXRect *)cellFrame inView:controlView - edit:(const NXRect *)aRect inView:controlView editor:textObj delegate:anObject event:(NXEvent *)theEvent - resetCursorRect:(const NXRect *)cellFrame inView:controlView - select:(const NXRect *)aRect inView:controlView editor:textObj delegate:anObject start:(int)selStart length:(int)selLength - (BOOL)trackMouse:(NXEvent *)theEvent inRect:(const NXRect *)cellFrame ofView:controlView -------------------------------------------------------------- do not use the Matrix method getCellFrame:at:: to determine the cellFrame argument that gets passed in each method. My question is, why not? I can see a possible speed improvement where each method gets called by the Matrix object without needing to call getCellFrame:at::, but is the speed improvement that great that it is worth throwing out the ability to create an easy subclass of Matrix to get different sized cells? It is easy enough to override methods in Matrix and Cell for all of the above methods with very little code. The only exception is that the mouseDown: method of Matrix has to be rewritten to send the correct tracking calls to the right cells and deal with the selection mode, etc... the mouseDown: method of Matrix doesn't even call - getRow:(int *)row andCol:(int *)col forPoint:(const NXPoint *)aPoint which I have also overwritten to handle the different cell sizes. Does anyone have an alternative to rewriting the mouseDown: method of Matrix, or some code that probably mimics the Matrix mouseDown: method (handling Shift-selected cells and cell ranges, etc.) I'd just rather not reinvent the wheel on this one, but.....

The value returned is always 0, regardless of how many rows are returned by the current command! Linking against the library which comes with 3.0 (v.4.0) works fine. In my sample-code my existence()-function checks for existence of a reord in a table. It uses DBROWS() to get a count of the existing records. It is called once before the data is inserted into the footab table and after the operation: Both times the existence()-func returns 0 (zero) !!!! This is not correct! Personally I won't rely on the 3.1 Sybase-library. The consequence is *NOT* to use the DBKit in 3.1 in conjunction with Sybase, and to link all other (not DBKit) programs against the 3.0 library which seems to work.

Below, you'll see a (DBValue) ivar named scratchValue first used to retrievea string from a "name" field. This succeeds. later it's used to retrieve an object from the same record's "imgae1" field. Though -objcType reports that the type is an object, -objectValue reports 0x0. What's the fix? Indeed, what I need is the natural generalization: to type an Sybase image field as Object in DBModeler, rather than NXImage, then dynamically store, retrieve and appropriately present custom classes of objects. has anyone done this?

This is a simplification, and not a very good one; these type of questions come up often enough that a better explanation should be put into the FAQ -- any volunteers?

If so, how do I do it safely? 2) Is anyone using the Indexing Kit for very large databases, like 300,000+ records? If so, what problems should I look out for? I am in the process of creating a database that will grow very shortly into about 500,000 small records. What sort of performance can I expect to get? 3) How do you find out the id of the IXBTree that a IXRecordManager is using? I want to know so I can send the IXBTree messages directly. This is my first "major" use of the Indexing kit, so any help would be greatly appreiciated. John Zollinger slv0y@cc.usu.edu

Date: 4 Aug 93 00:56:56 MDT Message-ID: <1993Aug4.005656.4321@morgan.cs.utah.edu> Followup-To: comp.os.ms-windows.advocacy,comp.os.os2.advocacy,comp.sys.mac.advocacy,comp.sys.next.advocacy Organization: University of Utah Computer Science [Followups redirected to the advocacy groups only.] [ Below is an article from IBM's OS/2 Developer (a publication roughly corresponding to Microsoft System Journal for Windows). It is about Taligent, the joint venture between Apple and IBM. Keep in mind that the OS they are talking about originally was Apple's "Pink" OS. Joe Guglielmi, CEO of Taligent, paints a much different picture of what Taligent will be, than what I knew of "Pink". Pink had it's own microkernel, was already running a Macintosh "personality", and while was not production code, was out being demoed at Apple NDA meetings. Unfortunately, I have all this third hand... if anybody knows of a good source about "Pink's" state pre-IBM I be ver interested in seeing it. Throughout reading this article I kept wonder how Mac users would feel about IBM's view of where Taligent is headed. IBM users have plenty of alternatives... but System 7 is too primitive, and Taligent (previously known as Pink) was supposed to be the next step. It looks like IBM is in the process of causing mass confusion. Anybody know of a source to read Apple's side of this story? It looks like to me that IBM is in the process of OS/2-izing (lobotomizing?) it. My comments appear between [...] like this one does. ] ------------ [OS/2 DEVELOPER; June/July, 1993; pages 6 through 20] TALIGENT: A NEW PARADIGM, A NEW APPROACH By Bob Orfali and Dan Harkey To OS/2 developers, Taligent can seem like a "Land of Oz" of operating systems, located "somewhere over the rainbow." Why worry about? Taligent when our brain cells are overloaded just trying to digest new OS/2 features like DSOM, the microkernel, DCE, LAN NetView, and motion-video multimedia? Why should OS/2 developers like us need to know about Taligent? At least that was our attitude when we began this article--but it soon became evident that there was a lot about Taligent that OS/2 developers need to know about. [ I found this paragraph a strange way to start the article... it's clear that most OS/2 developers outside IBM are very cognizant of Taligent... did they think this paragraph would fool them into believing they're the only one interested? IBM (the OS/2 portion) knows of this interest... as prior to this they have take every opportunity to downplay Taligent. ] A NEW PARADIGM? The first thing we discovered about Taligent is that its technology is multifaceted, elusive, and would not fit neatly into our current model of "the way things are." For this article we were not provided with specifications, product sheets, demos, or an architecture reference model. And this operating system is not like any other; it's all new and different. When we expressed our bewilderment to Mike Potel, Taligent's vice president of technology, he joked, "Joe Guglielmi had the same problem when he became CEO at Taligent. Every time he talked to somebody, he got a different view of this beast." This article starts by looking at Taligent from an OS/2 perspective and provides a framework for the terminology of the interview. We then turn the microphone over to Joe Guglielmi. We could never match Joe's eloquence and passion for his product. OS/2 AND WORKPLACE OS When does Taligent enter the picture? In Figure 1, we offer a "fearless forecast" of how the desktop operating systems from IBM and Taligent come into the picture over the next few years. In all cases, the future lies in operating systems that embrace object-oriented technology. OS2 2.x is optimized for Intel processors and will continue to evolve throughout the '90s. The Workplace OS is a portable environment that is designed to run on top of Intel and RISC hardware from a variety of vendors, with the portability layer provided by a common microkernel. The 32-bit OS/2 applications you create should run on all platforms. In our scenario, objects become very important. Distributed object services based on the System Object Model (SOM) become a vehicle to share objects across operating systems such as OS/2, DOS, Windows, UNIX, AS/400, and MVS. In addition, object-oriented application frameworks containing both IBM and Taligent technology will be offered for OS/2 2.x, UNIX, and Workplace OS. In Figures 2 and 3, OS/2 2.x and the Workplace OS support DSOM, object services, and the object-oriented application frameworks. OS/2 2.x and the Workplace OS support DSOM, object services, and the object-oriented application frameworks. OS/2 2.x continues to evolve, providing optimal performance on the large installed base of Intel machines. A GUIDE TO MICROKERNELS, PERSONALITIES, AND FRAMEWORKS Figure 3 helps explain all the new terminology and shows where Taligent fits in. Several pieces of the Workplace OS play together; the IBM microkernel, the operating system personalities, the distributed object layer, the object-oriented frameworks containing Taligent technology, and the Workplace user interface. We will briefly introduce these pieces, then move on to Taligent. THE IBM MICROKERNEL utilizes technology from Mach 3.0 research. Mach 3.0 is a portable microkernel developed by Carnegie Mellon University. The IBM microkernel and Mach 3.0 remove the UNIX-specific elements and provide a few well-defined services--including interprocess communications, virtual memory, ports, task dispatching, and threads--used to build all system services. The rest of the operating system functions--file I/O, user interface services, device drivers, and communications--are implemented outside the microkernel. As a result, the microkernel can be smaller, faster, and more scalable while providing a higher level of robustness, security, and integrity. Elements outside the microkernel, such as the device drivers and file systems, can be shared by the operating systems that run on top of it. IBM's multithreaded microkernel supports symmetric multiprocessing, a technique that allows programs to run concurrently on multiple processors in tightly-coupled configurations. It is intended to support Intel and a variety of RISC processors. TALIGENT AT A GLANCE Founded in March 1992, Taligent is an independent system software company owned jointly by Apple Computer Inc. and IBM Corp. and headquartered in Cupertino, Calif. The company has 310 employees, who use object-oriented technology to develop system software from the bottom up. The emphasis of the company's charter is on enabling the innovators and entrepreneurs who spawned the desktop revolution, allowing them to take full advantage of object technology's benefits and encouraging a new model for innovation centered around objects. Taligent's system software will be open for extension at all levels by software developers, hardware OEMs, and systems vendors. The company will license, market, and support its software platform worldwide. PERSONALITY MODULES provide operating system-specific API services. IBM intends to support DOS, Windows 3.x, OS/2 2.x, and UNIX personalities, with the microkernel concurrently executive multiple operating system personalities on one machine. (One personality, designated as dominant, controls the appearance of the desktop.) The personalities will preserve investments in code and application packages. The microkernel also provides the means to build spec- ialized servers and operating system replacements. THE DISTRIBUTED OBJECT LAYER, based on IBM's Distributed System Object Model (DSOM) technology, allows objects to operate across networks. This layer also includes services for storing, replicating, shadowing, creating, destroying, and specifying objects. DSOM is based on standards set by the Object Management Group (ONG), an industry consortium of over 200 member companies. For example, DSOM defines objects using the Common Object Request Broker Architec- ture (CORBA) interface definition language. DSOM uses OMG's specification of an Object Request Broker (ORB) to find and invoke objects on different machines. The object services are intended to comply with OMG's object life cycle and persistence specifications when they become available. OMG and IBM are also working on specs for shared objects and object transactions for client/server environments. All this means that OS/2 is already deeply involved in objects, adhering to current industry standards. These objects are, of course, built on top of a standard operating system. THE OBJECT-ORIENTED APPLICATION FRAMEWORKS intend to provide a portable distributed set of object services to help create user applications. A framework makes writing object-oriented applications from raw class libraries less tedious; you begin with complete working subsystems, which can be customized for individual applications. You can also create applications by writing subsystems together with visual application assembly tools. Third party software companies will be able to provide parts or entire components that can be assembled or modified by users or system integrators. THE USER INTERFACE for IBM's "Workplace" line is (you may have guessed from the name) based on OS/2's Workplace Shell. This object-oriented user interface will be adapted for DOS, UNIX, and OS/2. Users think in terms of directly manipulating objects on the desktop rather than dealing with programs and other computer- based metaphors. IBM is working on making the user interface even easier to use by adding powerful new visual metaphors. Now that we've introduced some of the terminology, we give the floor to Joe Guglielmi, the chairman and CEO of Taligent. We used the system detailed in Figure 3 as a reference point for our questions. _Developer: Let's start with one of the loftier questions. Taligent was jointly founded by IBM and Apple. What were your original goals, and how have they changed?_ Joe: When Apple and IBM got together on this project, it was because both companies had a common vision of the importance that object-oriented technology would have in the marketplace. Both had substantial interest and investments already in that technology. We first looked at a joint development using the Power PC RISC chip and then it grew into a more encompassing project that would com- mercialize objects on high-volume platforms and get the industry to make the transition from a procedural world to an object world. _Why is that so important?_ Because our goal is to provide a dramatic improvement in the application development environment. I talk about it in terms of moving the cycle from years to months and providing a brand new environment, in terms of functionality, that will encourage innovation. It also turns out that, since we're writing an operating system from scratch, we get to do some things right. We now have a rich heritage in multimedia, advanced graphics support, and other capabilities that we know should be fully integrated into an operating form. So as a kind of a Luck Strike Extra, you get to do those in an integrated fashion. By the way, in an object system all those things become simply objects that you can deal with. You don't worry about whether you're dealing with full-motion video or whether you're dealing with static date types. Everything is treated as an object structure. _Where do you see this technology going?_ We see enormous potential in this technology--not because it's object-oriented, but because it can give the industry a brand new base that will allow us to move from today's environments, which are constrained, we think by the operating system capabilities. Just as OS/2 2.0 unleashed the power of a microchip we'd been shipping for years, this will begin to unleash the power and creativity in the industry in a different way. We won't be constrained by the old paradigms of procedural operating systems. _How will you get this technology into the marketplace?_ This is where our strategy has changed dramatically. Initially, the notion was to deliver one large brand-new operating system, top to bottom, in one really significant drop. We've become more realistic about that; we've had to deal with very pragmatic issues. How do we, when providing this great step function, deal with current investments? How are we going to make sure the OS/2 invest- ments, AIX investments, System 7 investments carry forward? How do we ensure that we don't force a change in the marketplace all at once to a new technology? _So how do you do that?_ We've focused our strategy over the last year on three or four things. One is moving the project from a research project with two or three technology bases to a product development environment where we now have the focus on delivering products that respond to customers' requirements to the marketplace. Second, we've spent a lot of time staging the project...we can't do it all at once. We'll never be able, in one release, to compare to those established operating systems, so that's a bad goal. So let's focus on areas in which we think the technology substantially leverages itself. We're going to stage our technology to focus on both corporate and software developers. What do they need first, to provide value? Taligent's proposition is that the value comes from the devel- opers. We don't compete with them for word processors or spreadsheets, and we don't do databases. What we provide is an environment that lets them do a much better implementation of what they do best. Our delivery channels--Apple, IBM, and others--are also going to add value to this. _Yes, but every new operating system needs to do that kind of stuff..._ It does. But the second new notion is that we would take pieces of this technology and make it available to current operating systems like OS/2, AIX, and System 7. That's a pretty profound change. That's something that's not very natural for a team developing a new operating system to do. A development team wants to make the biggest step function change, one that differentiates between current and future environments. Well, we concluded that without some strategy to get the technology into the market early, the step function was too great. This isn't 1983 anymore. This isn't about "I have a great technology; we'll just get people to stop what they're using and move over to it." We have example after example in the marketplace today where great technology can't get commercial acceptance. So the notion was, why don't we take pieces of this technology and make them available to current operating systems? _What does that do for those operating systems?_ First of all, if we've done classy implementations of the technology, it will enhance them. OS/2 will be more competitive; System 7 will be more competitive. By the way, we're not limiting it to just those two; our strategy is to go after as many of the current operating systems as possible. Think about all the UNIX environments or--ultimately--any 32-bit system that can carry the technology. _What are the benefits to Taligent of making this technology available to others?_ The technology will make OS/2 and System 7 more competitive and they, in turn, will provide us a transition platform for the wide-scale introduction of objects to the marketplace. We benefit if IBM and Apple evangelize object technologies and provide us with a more evolutionary path. We're a small company; we can't do it all ourselves. But by putting pieces out in the marketplace, we begin to provide a transition mechanism--that is, investments made in applications that use that technology under a mature operating system can be carried forward into Taligent when the time is right. So when Taligent comes, customers can decide whether they want to move to it or not. this is not a forced march. It doesn't mean one Monday morning OS/2 goes out of business or System 7 goes out of business--that's not the strategy. _But if you've made your object technology available on other platforms, why would anybody ever want to move to Taligent?_ Taligent will be fully object-oriented with a very consistent object model. When you enter Taligent, everything in the system is an object, with no differentiation between a system object and an application object. We can implement a very consistent object structure once you're in the object space, you can leverage every element in that environment. You won't ever have to deal with the procedural elements of a system. Take NextStep, for example. Steve (Jobs) has a great user interface tool, but you still have to bounce into UNIX from within your applications. _Where are the advantages of having objects at the operating system level?"_ Envision a growing industry that would provide system frameworks, networking frameworks. Take communications. If they don't like ours, IBM or Novell could replace it with their own implementation. Device adapters can inherit characteristics of a particular device class and customize them to fit their particular needs. It's a very consistent way of taking advantage of new hardware. System software can then keep up with fast-moving hardware technology. _OK, so what's in it for application software developers?_ If we do our job right, in the mid-90's application developers will not be writing code but will instead be shopping for objects. If you think about it, there will be thousands of objects; how do I know which one I want to subclass or reuse? We're building a very consistent development environment with viewers or browsers that let you try out these objects and understand what they can do for you. You'll have a full environment that lets you think of your world in terms of objects. _Will some of that environment be made available on OS.2?_ Yes. I didn't mean to imply that the layers of components we provide for OS/2 won't be great; they'll move objects forward and condition the mass market for objects. Taligent has the added luxury of being able to put the whole thing together from the bottom to the top. _Speaking of the bottom, both Taligent and OS/2 will be running on the same Mach 3 microkernel--is that correct?_ We're on the same microkernel, but IBM is not shipping Mach. They're shipping a microkernel based on Mach technology. Mach is a big, heavyweight thing; IBM and Taligent are creating a much more lightweight version of Mach and creating personality-neutral servers and services. Taligent is adding the mechanisms to make it a first-class object environment. We're working on the performance implications of moving thousands of objects around in a system. IBM will build the microkernel that we'll use as part of our common strategy. [ By here it seems clear to me that IBM has forced a total redesign of Taligent (Pink had it's own Microkernel). ] _Mach is an open microkernel, something perceived as a benefit. Aren't you losing that by going to your own microkernel?_ I'm not commenting on the open aspect. I'm commenting on Mach's poor performance for doing objects. We have over four years of experience writing microkernels for objects, and we know how to do one. Object people don't think you can do objects on the current version of Mach--it may be OK for doing UNIX-type things. The common IBM microkernel solves those technical problems. On the openness question, it's up to IBM how they supply the microkernel back to the industry. I'm trying to answer the guy who says, "What are you, nuts? Mach can't run an object system the way it's currently designed." The answer is "It can't, but the kernel we're implementing can." It's really this notion that the core technology is optimized object technology and this new common microkernel works across OS/2, UNIX, and ultimately, hopefully, the industry. That's where the world's going. [ So much for IBM's "commitment" to Open Systems! ] _So is this microkernel one of the first pieces to be delivered?_ It's actually being developed at IBM. Our operating system development team is working with the IBM team. _Are your object frameworks built on SOM and CORBA technologies?_ I think we've come to appreciate what SOM is and what it isn't. I think there's a greater feeling that SOM's design point and the problem set that it solves are important, very important. Whether or not we can, as a team, adopt all of the goals of SOM in our design point is the discussion we're having with IBM now. The reason is, I think, pretty neat to think about. In Taligent, we are dealing with a system optimized for a very large number of small objects. That's how we get performance. We don't move a few big objects. We move a lot of very little things around, we we have a tremendous amount of tasking going on. We've got the machine burning and we've optimized for performance. We got a lot of value out of that optimization. SOM is best when the primary objective is mixing objects from a variety of vendors. The fact that the object's interface is the standard defined by the Object Management Group--the CORBA specification--is also very attractive. [ Translation? IBM forced SOM down our throats, but we're coping. Clearly SOM things written for OS/2 currently will not be easily portable to Taligent. I'm surprised there is no mention of migration facilities... i.e. how do PM and Mac ToolBox fit in? ] _Will you support DSOM then, since it's based on CORBA?_ Of course, DSOM is a very easy case. Its ORB, which is CORBA compliant, is one way we deal with objects across networks. We know there are objects on this network that are going to be moved around. _So you're depending on DSOM to bring CORBA. Is IBM representing Taligent's position in the OMG?_ IBM, like Sun or HP, has put some time into defining the CORBA compliance specs. In our implementation, we support that spec as one of the important distributed object models in the industry. Now take Microsoft; they're doing CAIRO. I don't know if CAIRO is CORBA compliant; the likelihood is not. What's going to be our position on Microsoft's model? If it's a high-volume model in the future, we're going to have to find a way to support it as much as possible. That doesn't mean we like it...or don't like it. Our position is pragmatic. We have to exist with whatever becomes a high-volume platform in the future. We're working with IBM, Apple, and others to try to make the transition as seamless as we can, but we're coming from two different worlds. What we won't do is suboptimize our world. If we end up lowering our goal of full utilization of object technology, we will lose the great differentiation that comes from it. [ Note, he does NOT say that they'll support DSOM. ] _Which IBM groups do you work with on object technology?_ I deal through the PSP division, which means that Larry Loucks, Cliff Reeves, and Lee Reiswig are my contacts in the IBM world. So when I deal with Larry and Cliff, we either agree or don't agree, and I expect them either to bring the rest of the company with them or tell me that I've got to deal with the situation differently. By the way, they're doing a great job evangelizing Taligent within IBM. _If you were speaking directly to, let's say, leading edge OS/2 application developers who want to do the right thing and position their product for the future, what kind of strategy or recommendation would you map out?_ Here's the strategy I think has to be followed. If you're an OS/2 developer, keep working with OS/2 release 2.1 and beyond. This will give you the highest affinity with Taligent. Why do I say that? Because I'm working very hard to make that happen. Can I [ So what happens to Mac developers? (see below) ] tell developers that everything they do in every release will be cared for seamlessly? No, I can't tell them that. But they should know that we are working very hard with the PSP development group to put as much of this technology as possible into OS/2 and AIX, to enhance their competitiveness wherever we can, because we believe that's good. We believe a big OS/2 base is in Taligent's interest and, therefore, we're going to work as hard as we can with IBM to make it as painless as we can. We hope it's zero pain. That's our goal. But it probably won't be. _How do you balance that with Apple's needs?_ The same way. When we talk to Apple, I have the same strategy. The decisions we make optimize on where Taligent is going, mindful; of the fact that helping make Apple successful with System 7 and IBM with OS/2, AIX, and Workplace OS is good for us, because every user in those two or three camps is going to be positioned much better to come to Taligent. [ Oh, so both will have the "highest affinity"... but there are huge differences between the two API sets... it is impossible to "integrate" them. Is he just talking air? ] _Will the Taligent user interface look like Mac, Workplace Shell, or something brand new?_ That's unclear, frankly, and let me tell you why. I believe that the opportunity to build the Taligent desktop completely from an object paradigm gives us degrees of freedom that can move the desktop beyond what is possible today. So we've focused on that; we're trying to figure out where we can exploit this technology the best. Let's take one model that could happen. In a Taligent world, since everything is an object, applications don't exist the way they exist today. You turn your system on and it comes up with a set of objects that you deal with, and you arrange them in the workflows. The notion of a workflow world centered on the user is much more realistic in a full-object world. Everything on the screen is a full object linked from the top to the bottom of the system. When we are ready to deliver a full-object model to the screen, we're going to go back and work with IBM and others on where they are today. We'll try to make it as evolutionary as we can...we'll find ways to see if we can't evolve multiple releases of the Workplace Shell or the Mac look to where Taligent is heading. _What's your planning horizon?_ We're the only ones in town who are worried about 1996. I don't mean that in a negative way. Everybody else is worried about 1993, '94, and '95. I have to stay worried about 1996, or '97; how can this technology, when it's fully exploited, change the playing field in the industry? If we miss the goal of providing dramatic new technology, the industry won't change. If the industry doesn't change, none of the interim operating systems are going to be successful by themselves. They will not have the kind of critical mass that you require. So the design point is to fully exploit the technology and then look backwards to see how we move the current base from here to there, and there are several bases. But the thing people ought to feel good about is that we're thinking about it. It's not like we're over here doing our best thing and hope that someday it all works. This is the first time there is a group that is allowed to really focus on where we want to be. At IBM, you know that there can be terrible constraints on getting there when you must suboptimize to support the core installed base. But we don't want to look like we never talk to each other, either, so we have a new development model here. It's different than we've ever tried before, and that's why Taligent is a separate company. _Will Taligent technology bring together the System 7 and OS/2 worlds?_ As a separate company, I can talk with a lot of authority about what we've doing, and I can tell you only a little bit about how we're working with these two companies. If you want their view of the world, you've got to go ask IBM and Apple, I will tell you this: both Apple and IBM feel strongly about keeping their current systems viable, and we support that. There's no model here, under any circumstance, where all of a sudden on Monday morning OS/2 or System 7 goes away. That isn't in the cards, because there's no viable scenario where this whole thing can make the transition in one day to a new environment. So there is going to be, as you expect, a continuation of a substantial investment in those current operating systems, and we're going to find a way to make the path to Taligent very attractive. _Are you going to sell a shrink-wrapped Taligent through software stores?_ Yes, but that isn't our model. The whole distribution model is changing today. The store distribution model is going away; I mean, who distributes operating systems today? The hardware manufacturers. So our strategy is to get the distributors to accept the technology, to provide the critical mass, the target volumes, so that developers can see it. Shrink-wrap and user sales will come after that. So the whole model is different. It isn't about running big ads in magazines, hoping that users will ask developers to create a great application. It's about going to developers and saying, "Look, you're building a great application. You can keep doing it. We're going to give you the tools to do it in a third of the time and to maintain it more easily by an order of magnitude. You know, by the way, that when you upgrade it, your cycle will go from two years to six months. That's worth a lot by itself. Oh, there's another opportunity coming. Have you thought about spreadsheet engines, word processor engines, graphics engines? Have you thought about work flow as an application? You can really do it now. Have you thought about it?" So we're creating a different world of applications and when we start this model, all of these characteristics will allow hardware manufacturers to differentiate their products. We want to sell through the high-volume channels. If we don't do that, our adoption curve is going to be seven years. It takes seven years to get an operating system to the market, if you're good. I want to be a success faster than that. So all of these strategies are working toward substantially reducing the adoption curve for the new technology. _How do you see the operating system pie divided in 1996?_ I'd be presumptuous to give you a target; I will tell you that existing systems will continue to have a large market share. Between now and 1996, there's just not enough time to substantially change the rate flow. I don't know what the division between NT, DOS, OS/2, and Windows will be; who knows? That's completely up to them. We haven't see NT yet, but they'll have a large share. I believe OS/2 will gain critical mass and have a substantial share. I think Apple will continue to have a big share. UNIX will probably still own eight or nine percent of a growing market. By 1995 there'll be 35 million micros shipped per year, so even 10% of that is still a big volume. And then Taligent will begin to show up. Now I can't tell you exactly how big our wedge will be, but it will not be zero, because we intend to get to market by the mid 90s; hopefully earlier. And I think that, as Taligent becomes an important environment and we demonstrate its utility, that wedge will grow more rapidly than historical growth rates in new operating systems. --------- Brian -- C.

The mechanism Bjarne proposes is actually generic and clean enough to be considered an extension to C, so it might just be considered as such and embedded in gcc as an extension to the core C compiler.

The problem in Bjarne's proposal is that you cannot have two "packages" or namespaces on toplevel with the same names. That is, you cannot have pointers to namespaces. In the dynamic OO tradition, a namespace would be an object somewhat like a class object in Smalltalk or objc.

Aside from the usual problems with the serial port drivers and (non-existence of) SLIP, which frustrate everyone as more and more time passes past NeXT's "mid-July" serial port drivers bug-fix promise, forget it, its too frustrating to even bother. The problem we're having is this: There are 2 DGX machines here equipped in the same way, they have 500meg IDE hard disks, a CDROM drive as SCSI device 1 and a 525meg QUICtape drive as SCSI device 2 on the chain. There is no problem accessing these under Dell Unix, but so far in a few minutes of playing with it, and trying: dump 0un dump 0unf /dev/nrxt0 /dev/rdh0a /dev/nrxt1 /dev/rsd1h etc, has met with failure to access the tape drive. The drives are standard units, which I think are made by Sony (Dell repacks the cases). What is the proper way to access the tape drive assuming its device #2 on the SCSI chain (the cdrom being 0, the tape being 1). thanks for any help or insight anyone has to offer! Paul

I wish to replace that Text object with my own but I wish to maintain all the same behaviors with a vertical scrollbar and text which resizes properly. How do I do that? A: The following code snippet will create an instance of your new subclass of Text and will insert it into the docView of the ScrollView. The old Text object is then freed. In the code sample ``theSV'' is an outlet connected to the ScrollView. Because an existing ScrollView is used, certain setups are not required. See Chapter 9, page 35 of the Concepts volume of the 1.0 Technical Documentation for more information on setting up a brand-new ScrollView.

It will be a quarterly periodical that contains information to help you develop applications in NEXTSTEP. For example, it might contain articles that provide background on how to make the best use of particular kits and tips on architecting applications. In general, we're modelling this journal on similar periodicals distributed by other companies, and we have a few good ideas of our own, too. In addition, we'd like some input from you on what information you'd find most helpful in a NEXTSTEP developer journal. For example: * Would you like more nitty-gritty details than the current documentation has, or overviews of how features were designed and how you should use them? * Could you use articles that explain basic concepts in UNIX and Mach? * Are there NEXTSTEP features that you'd like to use but have never quite figured out? * Would you be interested in what other developers are doing, and how they're doing it? * Would you find information on marketing third-party applications helpful? * What else could you use, documentation-wise, that we might not have thought of? * Would you be interesting in contributing articles on your NEXTSTEP development projects? Please send your suggestions and ideas directly to Cynthia_Closkey@next.com within the next two weeks. I'll send out another announcement later to let you know how to subscribe.

In my experience signals are caught by arbitrary threads. (I have heard that they are supposed to go to the first, but certainly this hasn't always happened under NS. Note that I haven't examined the source recently.) For example, sleep is implemented with sig_alarm, and I have seen this signal delivered to the soundkit thread and discarded. The main thread never gets its signal and never awakes. (Here I note that usleep(), msg_receive(), and select() can be used for thread-safe timeouts.) Until somebody tells me I'm clearly wrong, I would avoid using signals in a threaded app. -sam -- Opinions expressed herein are not those of my employer. They're not even mine.

I don't know if you got an answer to this; I didn't see one, but I think I missed a bunch of posts. One possibility is to use a function like the following (this is from the NeXTWorld Expo slides): ColorSpace ColorSpaceOfColor (NXColor color) { if (NXColorListName(color)) { return NAMEDCOLOR; } else if (NXEqualColor(color, NXConvertRGBAToColor( NXRedComponent(color), NXGreenComponent(color), NXBlueComponent(color), NXAlphaComponent(color)))) { return RGBCOLOR; } else if (NXEqualColor(color, NXConvertCMYKAToColor(...))) {... } } This function relies on the fact that a color can never be equal to a color from a different color space, so by testing the various color spaces, you can find which one a color came from. Not an ideal solution, but it might come in handy. A better solution is to get NXColor to make itself persistent, then store that. The NXWriteColor() function can do this; you can then take the resulting stream and convert it into a string. The ColorTest example from /NextDeveloper/Examples/AppKit shows how to do this.

That seems odd and troublesome. Any help is > appreciated.. > Yes, that's correct. The way DO works is that the calls the server's method, the corresponding NXConnection starts listening for messages on it's inPort...it has to because it's expecting a return message from the DO system with the returned value from the server! In the meantime, if the server *happens* to send some other message to the client, that's OK because it's listening and will forward messages other than the return message on to it's real object. It's kind of like the server saying to the client, "Oh, while I've got you're attention and you're waiting for me to finish this stuff, here, handle these messages." Once the client's connection get's the return message that it's looking for, it stops listening on the inPort, thus the server can't communicate with it. I think this point is sadly understated in the NeXT documentation on DO. Really the only mention of it that I found was in the Asyncronous Messages section of the IntroDistObj doc where it said: The server may send a message (like a callback) back to the client anytime the client's connection is running or the client awaits a reply from the server. This only *implies* that once the server's method returns, the server can no longer communicate with the client, unless the client has explicitly set up an NXConnection object to accept incoming messages. I just think it would have been useful to have a brief section called, "Setting up two way communication between client and server" or something like that. If you want to set up a two way communication, you can do it like this. After the client has gotten the NXProxy to the server, get it's connection using serverConnection = [server connectionForProxy]; and call one of the various run... methods in the NXCollection class to start listening on its inPort: [serverConnection runFromAppkit]; The runFromAppkit is just for illustration, naturally you would use the appropriate connection run... method depending how and where your client is running. As long as this connection is running, the server should be able to communicate back to the client at any time, not just from within a called method. You might also want to have the server call the client's registerForInvalidationNotification so that the server can know when the client's NXProxy is no longer accesible. Hope this helps.

In short, this is an intriguing practice that turns out to be very dangerous and should be avoided. At one time, I decided that it was very convenient to define ObjC's forward:: method to allow for forwarding to a "friend" object as the default behavior for Object's forward::. In so doing, I allowed for a simple form of runtime based multiple inheritance. To facilitate this, I overrode forward:: via a category method of the Object class and required the programmer who wanted to take advantage of this to implement a "forwardTo" method. This forwardTo: method would return the friend object for the receiver. So with one line of code we could get multiple inheritance for each new class in which it was desired. As an example, I implemented a class called PathList which contained a list of DiskNode objects as well as a good deal of additional information. I didn't feel like PathList belonged as a subclass of List because it was not a generic container, so I chose to make PathList a subclass of Object and have an instance of List as one instance variable. However, I wanted PathList to respond to any List message and didn't want to have to rewrite all the List methods just to forward the message on. In addition to the extra trouble of writing these trivial methods to do the explicit forwarding, it becomes a maintenance issue that every time a new method is added to the List class, it really needs to be added to the PathList class to keep them in synch. This was a major motivation for going with the simulated multiple inheritance. However, I now see the problem with this approach given that categories are available to all programmers who might be using my classes. Many months after I wrote the PathList class, I implemented some category methods for the Object class which make an Object conform to some of the List class' protocol. This is useful for allowing the programmer to pass either a List of objects or a single object without having to check to see whether a List or a single object was passed in the receiving method. [This is on the edge of what is considered safe practice, but after serious consideration, I believe all objects should conform to the List protocol to some extent -- they have a virtual container around them.] Once I had extended Object's protocol to handle the List accessing protocol, I caused a problem with my multiple inheritance simulation in the PathList class. This is because List messages being sent to the PathList class were not faulting as they were supposed to (according to original plan) and, therefore, were not being forwarded to the friend object of the PathList object. Instead, the List protocol that I attached to the Object class was being found and executed. I have come to the conclusion that the use of forward:: should not be used to simulate multiple inheritance. This example is but one of the many similar problems that can occur when using forward:: to simulate multiple inheritance. I think it is incumbent upon NeXT to promulgate more clearly the guidelines on how forward:: should be used. This is mainly because I have heard so many people saying they can use forward:: to pull some special trick, and the result is a serious collision of paradigms. NeXT has suggested that forward:: be used to simulate multiple inheritance (perhaps not in so many words, but I got the idea from their documentation). However, I don't think they anticipated the problem that I have encountered. I propose that forward:: be only used in conjunction with proxies that inherit from some other root object than Object. If this is done, then the problems will not be so wide spread since very few people should need to extend the implementation of the proxy root class, and the collisions that I have had will not happen.

Since CVS uses the underlying RCS to store and retrieve revisions, it relys on RCS's ability to handle binaries. RCS can actually handle binaries better than CVS can, because CVS is strongly biased towards the copy-modify-merge paradigm rather than lock-modify-unlock, and you can't merge binaries. You need to do tricks to get CVS to handle locking; this is what we do however, and it works OK.

I'm trying to use the setPath:(const char *)path method, and the browser doesn't react as I'd expect it to. I have checked to make sure I'm using the correct path separator character and I begin my path with the separator, since I want to start at the root level. The AppKit docs say that the browser will start at the root, look for a matching entry in the first column, and, if it finds one, load the next column if necessary, and continue in this fashion until the path is finished or until no match is found. Well, mine doesn't do this... Does it only work with a normal (non-lazy) browser? Any ideas? Thanks again, Scott

Inside Edit, the user asks another program to graphically edit a selected portion of text - that works through a service. But the problem is to write the edited text back into Edit's buffer. Only the modal (synchro) mode works, means Edit waits for the graphical editor to finish editing. But - what if the user wants to edit two graphical things at the same time. For the asynchroneous mode, I need a service like: get contents of buffer for filename and select/replace text in buffer for filename at... Maybe there is another way to communicate with Edit? How does gdb or the ProjectBuilder ask Edit to select a portion of a file? Will Edit be extended in 3.2? I would be very glad to get some help here from the net. Thanks in advance.

Basically what happens, is that project builder will compile with different flags depending on what architectures you have ticked. IMHO, it should behave the same way from the command line thru regular make, currently it doesn't. It ignores all architecture information and just builds m68k object code. This is because the whole thing is a bit of a hack really. To fix it you have to define RC_ARCHS = m68k i386 RC_CFLAGS = -arch m68k -arch i386 Even then to operate from the command line you have to , unless you patch common.make's (ARCH_LIST) define OFILE_DIR to be OFILE_DIR = m68k_i386_obj and RC_CFLAGS should be derived from RC_ARCHS it currently is not in the standard makefiles which look like this. (common.make) RC_ARCHS = `/usr/bin/arch` RC_CFLAGS = -arch `/usr/bin/arch` The obvious solution I think is the build the whole thing so that it stores the architecture information in the PB.project and eventually the Makefile and then go from there perhaps? Please correct me if I'm wrong. Well today has been a rewarding experience :-)

We've done various things to increase the number of cases Schematik can catch and kill the Scheme back end, and have even put in a bunch of code to make sure that if a gentle kill doesn't work in a reasonable period a SIGKILL is done instead. The number of runaway processes has continously gone down, but never completely to zero, despite a lot of effort on this. So.... my question is, why do the orphaned processes run any how? The basic problem is that certain interactive programs, including ftp for example as well as scheme, will go into a tight loop running forever if their input has gone away on them, rather than quietly dieing on a SIGPIPE, SIGHUP, or plain old EOF, as one might expect. For example, try this experiment: run ftp get a big file while it is getting, contol-z it and put it in the background close the shell If your experience is like mine, the ftp program when it gets done transfering the file and tries prompting for a new command will go into a tight loop, eating up CPU cycles like they were going out of style. A little gdbing around seemed to indicate that this was caused by repeated signal delivery in some I/O library routine or other -- I've forgotten the details. I never did really figure it out. I'd love to, though, because if we could make the orphan die quietly (or at least sleep rather than run) that would be much better than trying to catch every possible case of the parent going away and make sure that the child is always explicitly killed. So... does anyone understand what is going on in these madly running orphans? Any ideas on how the problem can be resolved on that end? Many thanks. -max

Error Sender: news@netnews.louisville.edu (Netnews) Message-ID: <mabroa01.744602096@starbase.spd.louisville.edu> Date: Fri, 6 Aug 1993 01:54:56 GMT Organization: University of Louisville Greetings, O Mystic Masters of the Black Arts... Once again I am plagued by strange programming bugs. This one seems to be a compiler bug though, and not really within my purview. I wrote a medium-sized (~350 lines w/functions included) piece of code in C to extract pitch period data window by window from a named .snd file. The program works just fine - as long as the size of the FFTs is #define'd as 1024. If I change the value of the define to 2048 (which I am going to need to do) the program generates a 'memory allocation error: attempt to free or realloc space not in heap' error followed by a 'bad zone' and an 'IOT trap' while inside a call to cfree(). As I say, I don't think that there is anything wrong with the program, except possibly that it uses a fair amount of data storage (4 arrays of 2048 float values + 4 dynamically allocated arrays of ~300 float or int values on average). This is hardly the first problem I have had with this piece of code. When I first got it to compile, it was crashing inside an if() with a bus error. While tracking that down with debugging print statements (Got Here!), I discovered that placing a certain printf in the proper place eliminated the bus error, and caused the code to run OK. Replacing the printf with a call to SNDFree(), which should have been there in the first place, caused a different error; a segmentation fault in a for() loop. Again, properly placed debugging statements cleared up the segmentation fault, but one of the values in the loop was being overwritten after its first usage. And yes, you guessed it, a debugging printf in the current code causes it to run 'perfectly' as well, even at FFT_SIZE 2048. So I can get the code to run. On the other hand, this is only the first half of a pitch and formant extractor, and I am not sanguine about the prospect of searching that code for its magic debugging statements. I have tried playing around with gdb, but I'm not really sure what I'm even looking for any more, and I'm am learning gdb as I go. If this were Turbo C on an x86, it appears that I would be looking at segmentation problems due to my program memory size, but it's a 68040 under NeXT's Gnu C modification, so I'm damned if I know what to do. My machine is a NeXTStation 8/400 running NS3.0. If any of this seems familiar, or you have any helpful comments, please email me! If you are interested in the code or the algorithms, I'd be happy to provide details via email.

What I did was to create a list of all the segments as I was drawing them and then use that list to do the erase operation. As I was trying to optimize redrawing (I only redraw what has been changed) I did not consider erasing the whole rectangle and redrawing from scratch. If you draw the same line twice with different colors and there are pixels left over, it's a bug.

I had a similar problem with a hash table. I wanted to store Classes, keyed by integers... which works great, till you try to save 'em. So I figured I would just subclass HashTable and change the -Read: -Write: methods... Wrong! Because Read and Write rely directly on calls to [super ], you can't do that. So there are two solutions to your problem: The first (and the one I opted for, for my own reasons), is to create a subclass of object, which "owns" a List, and forwards all of the messages it receives to that List (except Read and Write). In your read and write, just parse the List, using writeObjectReference() to store your objects to the current stream. The second (and in your case, probably the one to consider) is to create a category that overrides the existing -Read: and -Write: methods of the List. If you are worried about other Lists that you may have, create a sub-class of List, ReferenceList, and use the category on that. Have fun! (The actual coding should take about fifteen minutes) Kevin

Message-ID: <6AUG93.19265981@enh.nist.gov> Sender: news@dove.nist.gov Organization: NIST Date: Sat, 7 Aug 1993 00:26:59 GMT I have an NXImage that I need to composite to a view that has a very non- standard coordinate system. It is both scaled and offset, and adjusting the view is really not the right thing to do (I think). These images are going to be of variable size, and the offset is based on their size, so each needs to be able to deal with its own offset. Basically, I have images that need to be drawn at a center point, instead of the lower left hand corner. Does anyone have any suggestions as to what I can do? I am toying with sub-classing NXImage, and "modifying" the compositeTo: method, but I don't think that that is the most practical approach. Any and all suggestions are welcome.

Message-ID: <py$@byu.edu> Date: Wed, 4 Aug 93 15:21:42 MDT From: yackd@texas.et.byu.edu (Don Yacktman) Newsgroups: comp.sys.next.programmer Distribution: world Organization: Brigham Young University, Provo UT USA Subject: The DAYMiscKit (long) Keywords: free objects I have an interesting proposition/idea for the net at large, and would like to present/discuss it with interested parties. First, a little bit of background: As many (most?) of you know, I recently released a kit of objects called the "DAYMiscKit" which is a collection of free objects that I have created and found useful in my work. Things like a string class, a class to manipulate time(s), a stopwatch/timer, and so on. (If you haven't heard about it, or missed the csna post, you can grab it from cs.orst.edu or from ftp.byu.edu; in the latter case as /pub/next/daymisckit_proj.tar.gz) Anyway, the current release is under a "free" license (but which is not the GNU license). The idea is that anyone can use the objects for anything, without having to pay anyone money, and that noone but me is allowed to charge money for these objects and their source code. (And I'm not charging, of course. :-) I didn't use the GNU license because there are many folks, primarily commercial users, who cannot use objects under that license due to its restrictions and I want these objects to be useable by anyone. (Which is why I offer to sell support to those who need "official" support. The objects are simple enough that dupport is unnecessary, IMHO, but some bosses require this anyway...) Well, I bring all this up because Scott Anguish has suggested a very interesting idea. What if this kit of objects is turned into a library of objects that anyone/everyone can contribute to? Two examples: the current DAYString was originally my idea, but many of the most recent changes and enhancements were made by Carl Lindberg (thanks! :). And the second...Scott Anguish has a nice clock view on a palette which is going to be added to the kit, to work alongside the time objects that are already there. So, since the kit has already expanded beyond what I've originally done, why not make an open request for free objects which are small and generally useful, and throw them all in there? There's only a couple of reservations I have, and they have to do with (1) the "DAY" prefix I've been using and (2) getting a real license drafted up. First, the prefix. I chose it because (a) it was obvious--my initials-- and (b) it's not very likely that anyone else will use it, since my initials are somewhat a rarity. I wanted to be able to include others' string classes, for example, without having a name conflict and it seemed that this prefix would avoid that quite handily. "String" was just far too general, and since my DAYString isn't the end-all, be-all, there is the possibility that another String class would occasionally be used in the same project. The same goes for any of the other classes, of course. Well, thr problem is that I do not want to stick this prefix on every object that someone might submit, since I didn't write them...and sticking my initials into the name of an object that isn't mine obscures the original author's name, which wouldn't sit well with potential contributors, I'm sure. It seems the best solution is to come up with a good two or three letter prefix that can be put on _all_ the objects, future and existing, that will be in the kit, and dropping the "DAY". Any ideas? I'd much prefer to give all the objects the same prefix than just assign initials of whomever was the author--that could foster anarchy. Second, the license. Basically, the current one is fine as to intent, but I'm no lawyer, and would feel much more comfortable if there were an honest-to-goodness real license drafted up that meets with the intent of what I've done: free objects that require only (1) the user doesn't sell them to anyone--selling an app that uses them is fine, but selling them as objectware is not-- and (2) credit is given so that someone using the end product is (a) aware that these free objects were used in the app --info panel or in the documentation or both should contain a reference-- and also (b) sees a pointer to where to obtain source. One catch is putting it on a CD-ROM collection. What I'd propose in that case is to request free copies of the CD-ROM for all the contributors as a "payment." (Or is that too steep? I don't think it is myself...) So what this all boils down to, after all that is: (1) Who would be interested in contributing? (2) What would you have to contribute? Spefic objects? Help/patches to improve what's in the kit? etc... (I'm looking specifically for extensions to UI objects, like the AppKit, and common classes, like strings, trees, etc.) (3) What's a good 2-3 letter prefix that would be nice to use? (4) Could anyone get a real license drafted by a real lawyer? This is a free project, a gift to the world so to speak, so I can't afford to put any money into this; I'm a poor student who can invest nothing more than time...but if there's a lawyer who owes someone a favor... :) Anyway, as I see it, there are several advantages to this idea: (1) You get a kit of several useful, free, objects that are designed to work well together...not a hodge podge of classes that do what you want but are incompatible with each other. (2) It's all in one place: use the kit and compiles are faster because you don't have a zillion .[hm] files in your projects and tons of different .a files to link against... [If you regularly use many of the free objects off the archives already, you probably can see why consolidation would be nice for both development speed and also to have the objects work together well with a consistent API.] (3) Having others participate makes the kit become more useful more quickly. I am willing to be a source "moderator" -- ie. you can check in/out the source files through me, and I will try and go over them to keep bugs from being introduced. I know that a similar "community" project has been attempted with BackSpace modules; how has that worked out? (I've not watched it too closely...) The generality of the MiscKit makes it a good candidate for a collaborative project, since it will benefit a very large audience. So, what do you think? It seems that a certain amount of net discussion on some of the questions might be appropriate, while actual volunteering should probably be done directly to me via e-mail. If the discussion gets too me too much for the uninterested, I could create an e-mail alias to handle it, too... Awaiting responses... -don -- Don_Yacktman@byu.edu Nepotism is a relative thing.

I'm using: NeXT OS 2.1 NeXT IB 2.0 I'm trying to do something very simple: add a menu item to an existing public domain program (edsnd 1.42) that sends a message to the main window to print itself. Here's what I did: 1) I added a menu item to an application submenu named "Print" and made a connection between the menu item and the application object, which is an instance of a subclass of the Application class, more specifically a connection between the "target" outlet of the menu item and a new action of the application subclass that I named "print:" using the project inspector. 2) I added the proper declaration of the print function to the Application subclass header file and code for the print function to the .m source file, which looks like this: /* print: -- tell the main window to print itself */ - print:sender { id mainwin, PSret; if (mainwin = [self mainWindow]) { PSret = [mainwin smartPrintPSCode:self]; } return self; } 3) The code compiles no problem; I can run it under gdb, hit the print option in the submenu and sure enough the code gets called. Here's what happens: 1) Nothing is printed, and after ~30 seconds a popup warning panel appears, saying: "PostScript error: %%[Error:invalidid; OffendingCommand:newinstance]%%" 2) The application crashes, except sometimes when I'm in gdb it doesn't. When I do get it to crash in gdb, the trace looks something like this: Program received signal 11, Segmentation fault 0x500b000 in NXVPrintf () (gdb) where #0 0x500b000 in NXVPrintf () #1 0x502d37a in NXPrintf () #2 0x6068f94 in _DPSConvertBinArray () #3 0x6006142 in binObjSeqWriteGuts () #4 0x6006212 in _DPSOutputBinObjSeqWrite () #5 0x600d19e in NXSetGState () #6 0x600ac4e in _focusFromTo () #7 0x600abac in - [View lockFocus] #8 0x608b120 in toggle_cursor () #9 0x600cb30 in checkTEs () #10 0x600c9a4 in _DPSGetOrPeekEvent () #11 0x600e70a in NXGetOrPeekEvent () #12 0x6036ee8 in - [Application run] #13 0xca34 in main (argc=3, argv=(char **) 0x3fffe18) (edsnd_main.m line 12) The PostScript error and the crashing may be (somewhat) unrelated; not only can I get the PostScript error without crashing (under gdb), I have also crashed it trying to print without getting the PostScript error (when the printer was hung and its queue not moving). Other things to know: * I verified with gdb that it is correctly identifying the main window. * I tried it also with printPSCode in place of smartPrintPSCode, with same result.

Will the first applicable (m68k in this case) be loaded, or will the m68040 be better optimized for 68040 or will the two generated sub-binaries be identical?

It behaves in precisely they way you want. If you need something unique to a List then you could simply copy the pointers to a List after you unarchive the Storage object. Using Storage can get a bit ugly but there is an example in NextAnswers.

The latest is 5.6 and available from prep.ai.mit.edu and its mirrors. I fully concur that if two or more developers are working on a NeXT step application, you really need CVS. Because .nib files are directories, and if you have builtin help, they are .rftd directories you wind up with a lot of files and directories even for a simple application. With CVS, you can checkout the whole directory tree with one command, and after modification of files in any directory, to a checkin with one command. My current application, HippoDraw (soon to uploaded to NeXT archive sites), is a simple app but consists of 642 files in over 60 directories. Without CVS, I think we would go crazy. -- Paul F.

In fact, here is an excerpt from DevTools/08_MallocDebug/MallocDebug.rtfd under the subsection Identifying Damaged Nodes: MallocDebug detects nodes that have been written to incorrectly.

(same name, > ...of course) I might be misunderstanding what you're saying, but it sounds like when you add the libraries to your project, you're actually getting PB to copy them into your project directory. It makes no sense at all that your app is linking against the old version of your libraries if they have been physically replaced in /usr/local/lib. so here's a fix: Normally, when you add libraries to PB's Libraries section, it just makes reference to them in the Makefile, i.e. if you add /usr/local/lib/libfoo.a, PB now will add "-lfoo" to your link line. It's up to you to add the following to your Makefile.postamble file: OTHER_LDFLAGS= -L/usr/local/lib This tells the linker to also look there for libraries. Also, check your project directory and see if there are copies of your lib*.a files. Chuck them in the trash... Hope that helps. --> Michael B.

I decided to play a music CD using the CDPlayer.app found in /NeXTDeveloper/Demos. Logged in as any other user besides "root", the CDPlayer complains that it can't find the CD-ROM drive. The console error generated is " cdutil: opencd: permission denied". I have tried changing the group permissions to those of the root's default group for the other user, but it doesn't work either. Would anyone who knows why this doesn't work, or what does please tell me what to do. My NeXT is standalone and NetInfo is disabled. BTW, when I put the NeXT CD-ROM in the player, it gets put on the desktop for both root and user. Thanks in advance. ______________________ James Moosmann NeXT/E-Mail: moose@antilles.nosc.mil 703-786-0807 @ Home 703-602-8080 @ Work

Is this possible > somehow? I'm not sure I entirely follow what you're asking, and I've never actually tried this, but I imagine that if you use "lockFocus" and "unlockFocus" judiciously on, say, two different views, then the instance drawing would only affect the view you were drawing into, and you could switch between them. You use the word "context", however, which implies Display PostScript contexts. I would think the same thing would hold for drawing into different DPS contexts (although I wouldn't think you'd ever want to do this explicitly). -- Glenn Reid NeXTmail: glenn@rightbrain.com RightBrain Software 415-326-2974 (NeXTfax 326-2977) Palo Alto, California Electronic Frontier Foundation, member #054

In 2.1/2.2 the speed of grabbing screenbits, blowing them up, and redrawing was appallingly slow. This was cured in 3.0 (supposedly to allow the Mac Emulator Package - I forget its name - to function at any reasonable speed). With 3.1 we are back to the old 2.1/2.2 speed. Does anyone have experience of this? This is basically what I do: [[ imageCache contentView] lockFocus]; PSgsave(); curContext = DPSGetCurrentContext(); GetFocus (&c1x, &c1y, &c2x, &c2y, winCTM, &realWinNum); DPSSetContext ([NXApp context]); ReFocus (realWinNum, winCTM, c1x, c1y, c2x, c2y); PSgsave(); im = [[ NXBitmapImageRep alloc ] initData : NULL fromRect: &activeMagnifier ]; [im setSize :&activeMagnifier.size]; PSgrestore(); DPSSetContext (curContext); PSgrestore(); [[ imageCache contentView] unlockFocus ]; [view getBounds : &bRect ]; [self setupClip : view : &bRect : zoomFactor]; PSsetgray(NX_LTGRAY); NXRectFill(&magnifierBounds); [im drawAt: &activeMagnifier.origin]; [self removeClip : view ]; [im free]; s cured in 3.0 (supposedly to allow the Mac Emulator Package - I forget its name - to function at any reasonable speed).

The >basic problem is that certain interactive programs, including ftp for >example as well as scheme, will go into a tight loop running forever if >their input has gone away on them, rather than quietly dieing on a >SIGPIPE, SIGHUP, or plain old EOF, as one might expect. I have seen this with several interactive applications over the years. So what is going on? Let's look at common features of the programs which behave this way. 1. They are designed to be interactive, and respond to individual characters (in cbreak or raw modes). 2. They do not handle EOF. 3. They may or may not automatically respond to SIGHUP or SIGPIPE. 4. Look at the low level features. If you look at low level system statistics you'll find that they are CPU bound and that system call (rather than user code) CPU climbs through the roof. First, let's look at the runaway CPU activity. Lot's of system calls tells us that short fast system calls (that do not block) are being furiously executed in a loop. This activity is part of a general read/eval/print loop that uses select(2) to determine if input is present. while () { select(); . . . . if (ibits & inputmask) { read(); if (read_returned == -1) do_error(); if (read_returned > 0) do_work(); } . . . } many people fail to catch EOF when implementing such a loop because they misunderstand the semantics of select(). select() on input fd will return immediately when EOF is present. This immediate return makes many people think that actual input must be pending. In fact EOF is always pending on end of file, its just that this input is NOTHING rather than something. Since these programs do not generate output when they read nothing they will not receive SIGPIPE on write to a socket, or otherwise note that stdout is no longer valid. Thus these programs do not pay attention to EOF at all! The only way to ensure that they die gracefully is to arrange for them to receive SIGHUP when their parent dies. If the process does not attempt to make itself the Process Group leader (like shells do). You sould make the parent process a process group leader on the pty or tty that the session is running on. Then you can use the vhangup() if they know the parent will die. On abnormal death I believe that HUP wil be sent to the children automagically. If the child does not respond gracefully to either SIGHUP or EOF, all bets are off. Hope this helps. -- ___ ___ mail: uunet!phcs!jq PHCS, Inc.

Either in your program (not quite the > same line) or in Display PostScript (somewhat less likely, but not > impossible). Back to the sources to try to remember what was really happening... :-) It seems the problem was not a Display Postscript bug because when I stored all the points in a list the erasing was perfect (same points = same pixels). If I remember correctly the problem had to do with "calculated" intermediate points. They were calculated using floating point and trascendental functions (I was approximating an exponential by using linear segments). Even though the original numbers were the same and the code used was the same the result was not _exactly_ the same... and supposedly (that 's were I may be wrong) any round off error should be repeatable! Anyway, at the time I did not have the time to track this down so I labeled the problem as "round off error?" and hacked the point-memory-list pseudo solution. > That said, it seems to me that the intermediary position between "blow > the whole thing away and redraw" and "erase and draw as little as > possible" might be Instance Drawing, although Instance Drawing seems to > have become a second-class citizen of recent.

Unfortunately, some platforms (NeXT, Ultrix) have only the old version while others (SYSV) have the new version. The old version doesn't have any 'standard' way of catching special keys (all I need are the cursor keys). The function wgetch() simply returns all the characters the keys send.

I am almost finished reading Alex Nghiem's excellent introduction to NeXTSTEP programming. (NeXTSTEP Programming Concepts and Applications, PTR Prentice-Hall, Inc.). On pages 237-241 he has some discussion of instance drawing. Perhaps this would be useful to you. By the way, I strongly recommend this book. I also own the book by Mahoney and Garfinkel, and I liked it too. But I would say that this new one is a bit better written and selects its topics well. I think that, on the whole, Nghiem's book is a better introduction to NeXTSTEP. On the other hand, I think that the book by Mahoney and Garfinkel is presented at a little bit more of a nuts and bolts level and therefore presents more detailed information at times.

Maybe it's a bug, but I think it has to do with keeping the sizes of the parts appropriate, based on the font size in the browser cells or something like that. I'll bet if you constrain your window growth to some small number of pixels > 1, you won't see this. But you'll have to discover the small number yourself; I don't know it. Here's something else to try. I discovered it recently. Put a textfield below your browser, aligned on the right with the browser. Configure it to grow horizontally. Now stretch the window several times to the right, by one pixel each time. The browser does not stay aligned: it varies by one or two pixels. Steve abell@netcom.com

Obviously the conformsTo: method returns YES because BarWindow adopts the Foo protocol directly. If I remove the "<Foo>" protocol spec from BarWindow.h to get rid of the compiler warning, will the conformsTo: method return NO or will it still return YES because it recognizes that all objects must conform to the Foo protocol because of the category implementation?

My initial guess is to somehow use the copyPSCodeInside:to: method to get ahold of an image that I can then include in a "template" view, which I can send a printPSCode: message to...

I'm not sure I understand what *exactly* the problem is. Color Digital Eye does have a frame buffer, so it can capture an image from a single frame. This is what it was designed for. However, the original poster asked about a digitizer that would allow the NeXT to read the image "afterwards". What does this mean? It might suggest a device that would store a digitized image indefinately, until the data was downloaded via the DSP (or other port). In other words, a device one could use to capture an image "in the field" so to speak, which you would then take back to the lab to download. In this case, Color Digital Eye does not fit the bill since the capturing is initiated by the DSP.

Sender: news@netnews.louisville.edu (Netnews) Message-ID: <mabroa01.745049000@starbase.spd.louisville.edu> Date: Wed, 11 Aug 1993 06:03:20 GMT Organization: University of Louisville I'd like to thank everyone who took the time to email me or post responses to my debugging inquiries. Thanks to them, I am now somewhat familiar with the operation of the MallocDebug.App. (Special thanks to the person who posted the reference - I couldn't understand why everyone seemed so excited by the standard C malloc_debug().) I am also now fairly familiar with gdb. On the other hand, I still don't know what's wrong with my program. I now strongly suspect some compilation or preprocessing bug. I suppose it is possible that my compiler is corrupted in some way - I bought the machine used, and it appears to have been upgraded at least once (now 3.0). The smaller version (FFT_SIZE=1024) runs fine. MallocDebug reveals no leaks or node overruns. I can step through it line by line in gdb and every value checks out as being reasonable. The larger version (FFT_SIZE=2048) compiles without error (or warnings, thanks again) and crashes with the aforementioned 'attempt to free or realloc space not in heap' error when run. When compiled -lMallocDebug, the program runs, generating a 'freed unmalloced pointer: 0x???' error every time through the main loop. MallocDebug shows a corresponding leak of size 4*??? each loop. The caller is listed as 'main, start', and the addresses are generally increasing from the largest listed for the original 'All' listing. The only other difference between the MallocDebug 'All' listings is an offset of 8k between their addresses. The data produced looks reasonable, except that one of the parameters has been modified. Inspection via gdb is useless - it 'loses' several important variables which the program is clearly getting. That is, the program would not work at all without them, but attempts to print their values or addresses result in the 'No symbol 'x' in current context' message. The variables cannot be read anywhere in the program, from the first line of execution on. They are fine in the smaller version. Values of FFT_SIZE larger than 2043 cause increasing amounts of 'lost' variables as the the #define is increased. My brain is melting. The program both works and doesn't work. (A & A') The source of the problem seems to be in the initial allocation of program and data segments, and this should NOT happen. Every 'problem' I've found in the code itself has turned out to be some innocuous statement which cannot be wrong. These 'problems' seem to be randomly generated within a particular version of the program. It appears that my only options are to attempt to check the entire memory map of the program address by address, or to attempt to examine the assembly code. Neither of these alternatives is appetizing, or, in fact, particularly feasible. How a single #define (it's just a label, after all) can cause so much trouble is beyond me. So, anyway, thanks again, and if these further symptoms clarify the problem any (esp. the gdb failure!), or you have solved similar bugs, please email me.

Yes, that is exactly what I mean. For example having two objects blinking at different rates (through the use of instance drawing) in the same window within two different views. It makes sense that judicious use of "lockFocus" and "unlockFocus" would have handled this, but it apparently does not. If I lock focus on one view, and PSnewinstance() to clear the view (to simulate the blink for one object), the object in the other view is also erased, even though its view is not the focused view!?

By context I mean an environment where instance drawing is performed.

Date: 11 Aug 1993 10:04:35 -0400 Organization: Virginia Tech Computer Science Dept, Blacksburg, VA Message-ID: <24au9j$bu6@csugrad.cs.vt.edu> I am involved in writing code for a modeling/simulation program. Currently all drawing objects (which are selected from a tools palette) are subclassed from the Object class. Detection of whether an object has been selected on the screen is accomplished by implementing mouseDown: and cycling through a list of all objects on the screen and performing an intersection routine on those objects whose largest enclosing rectangle contains the mouse click. I am new to NeXTSTEP programming, but it appears from all the NeXTSTEP programming texts I have that this same functionality can be accomplished by subclassing the drawing objects (e.g. circles, ellipses, lines) from the View class. Then all you have to do is implement hitTest: to both receive mouse events and determine whether the mouse click was on the object. I would like to know which method seems to be the "better" or more reasonable approach. I am not sure if subclassing from the View class will result in a performance loss. The literature would seem to indicate that the test for the largest enclosing rectangle is implied by subclassing from the View class, that is, only those subviews containing the mouse click in their rectangular area will get the mouse click event. However, if ALL subviews got the mouse event, that would be a waste of messaging. I would appreciate any help, even pointers to other sources. Thanks, David Holcomb holcomb@csugrad.cs.vt.edu

[Lot's of very familiar emotion deleted.] Morgan, you are suffering from something that sounds an awful lot like lack of experience. Don't get me wrong, we were all there once, and I feel empathy because I have had exactly the same feelings not too long ago. Some of us still don't escape the really nasty feeling that it is "someone else's" code. But my experience says it isn't the compiler, MallocDebug, or gdb. It is your code. MallocDebug probably would show it to you if you looked at it at the right time, before it starts killing your program, gdb, and whatever else. I learned a motto once from someone. It goes like this: "If you have checked everything and you are sure it is right, but the problem remains, then something you are sure of is wrong." It really is that simple. When you find it, you will sigh and go on to create even bigger bugs. Sometimes a bit of time off will help. Sometimes someone else looking at it with an open mind will help. Sometimes just rewriting a suspect loop will do it. But I rather think it is lack of experience with some strange feature of C that is hurting you. If you have for loops with ++ or -- in them, unitialized variables, pointer mixup (using a number as a pointer, only dereferencing once, etc.), quiet numeric death (like 1/64 is 0, not 0.015625 (I found that yesterday)). Take another look at all assignments. You are overwriting something, somewhere. Look hard at assignments in loops, particularly ones that use your FFT_SIZE macro directly or indirectly. If all else fails, ask someone to come in on it. I would be willing to bet the pros reading this could find it in 15 minutes. Maybe we should have a contest?

A work around would be for you to define your own operator - "myarct" - which could be defined as "/myarct /arct where { pop /arct load } { { arcto pop pop pop pop } bind } ifelse def". Of course, you can no longer use the "PSarct" singleop, but you can easily write your own "PSmyarct" singleop if you want.

Why not just subclass Application and add this: int classHandler(const char *className) { id object; object=LOADCLASS(className); return (object != nil); } [Where LOADCLASS(name) is a static/inline function in an include file that uses NXBundle.] + new { classHandler("preloadedclass1"); objc_setClassHandler(classHandler); return [super new]; } The likely reason NeXT doesn't want to support Shared libraries is that they are enormously tedious way to maintain. What do people want shared libraries for? I'd rather NeXT come up with an efficient cleaner alternative. An object broker daemon, perhaps. Any guesses on 3.2 features?

If lockFocus and unlockFocus on your two views doesn't work now, try giving each view its own dps context. If you don't explicitly give a view its own context it draws in the window's context. Instance drawing may only allow one "instance" per context. So try it that way. A DPS context is, I believe, about as encapsulated as you can get in DPS, so if this doesn't work, I would begin to doubt its possibility.

Probably most important for a sophisticated view is to know where your pages are. If your view knows where its pages are, then it should implement -knowsPagesFirstAndLast and -getRect:forPage:. This will allow you to do your own pagination. Then there are many methods you can implement that the printing machinery will call for you. These methods allow you to do many different things, including adding postscript to the stream at strategic areas. One or more of these methods could be used to do headers and footers or page numbers, or whatever. Look in the General Reference Vol I. The View documentation has info on all these methods. In the method summary, the three sections to look at are "Printing", "Setting up pages" and "Writing conforming PostScript".

I can remember when I was quite the novice programmer. I'd program along (in Assembly and Fortran) and when things didn't work, I'd just work it through (much of this was on a Dec-10 with a rather limited debugger). Finally I hit something that I just couldn't figure out. I caved in and asked my best friend and mentor, Chris Caldwell, what the problem was. He futzed with my Fortran for a while and eventually said "compiler bug". (I didn't know enough then to verify that it was indeed a compiler bug, in fact I didn't even think Chris could be wrong. I'll never know about this particular instance). The trouble is that my ability to program temporarily took a major hit since everytime I'd get stuck I'd be sure I found a compiler bug and I'd cry out "Oh Chris!..." Eventually I got over my hangup, *but* now I know enough that I can find and verify compiler bugs myself. Executor and Mat's synthetic CPU push the compiler pretty hard (Fudd's law: push something hard enough and it will fall over). Just within the last month I found a bug in the assembler that was introduced in 3.1 (for you doubters, it has been confirmed as a bug by NeXT). Yahoo.

Currently, I have an app that dynamically loads many of the classes that we work with. Part of the reason is so these classes can be expanded after the program has been running... dynamic class additions are great. On the other hand, as soon as we have a class developed we intend to install it permanently in the main object code. Another problem, and one that might be more obscure is the following: Right now, attempting to make a class call such as: [[AClass alloc] init]; Only works if the compiler knows about the class. If it is dynamically loaded, you are forced to use the more cumbersome (and slower) objc_getClass() function. Because the function must look up a class by a string name, it is very much slower than having compile time references to the classes. In your scenario, the compiler would have to store an open ended reference to each class you use. At run time (or when needed), the system would have to go to an area on the hard drive (imagine the nightmare of coming up with a standard file structure for this one! BTW: the whole reason to use bundles is to avoid such a file structure), load the bundle, and associate each of the "loose" ends (left over from compile time) with it. To make matters worse: If you had a spelling error, the compiler would not know that it could not resolve the class pointer, and you would get run time crashes. If you think these things are hard to track down now!! The object oriented approach to programming has its advantages, and its dis-advantages, and I think it is important that we remember that we are dealing with a language (C) that is defintely NOT obj-oriented. In a true object oriented environment, the idea of having classes linked in through bundles would make a lot more sense: The operating system could keep track of classes in shared libraries, and you could get a class by making a simple request to the O.S.... just think about what the future holds!

Problem is that, if you have five apps that load a given bundle, you'll have five times the amount of virtual mememory consumed as compared to using shared libraries. Shared libraries allow sharing of compiled code across apps, so they save on runtime space as well as disk space (in terms of the size of the app).

I use tcl (the tool command language from Berkeley) in almost all of my projects. As a matter of fact, I'm using it in several Workspace Inspectors I'm writing. I also use tcl in the various palettes I've written for IB. I also use it in the loadable bundles I've written for 3DReality. I also use it in the sound server I wrote. I also use it... Anyway, you get the idea. tcl is a reasonably large, stable, portable piece of ANSI C code that works just fine, and although I have a TCLInterp object that provides a nice OO cover, that is orthogonal to whether or not I want a shared library version of that library of code. It sure would be nice to have a libtcl_s.a (or whatever their naming convention is) which all my various apps, bundles, palettes, etc. so that the code was loaded into memory once, As opposed to (right now in my system) the one linked into Workspace.app (because of my inspectors), IB (because of my palettes), 3DReality (because of my bundles), and the 4 apps I'm running right now (because they use tcl as their interapplication language).

I was interested in seeing some kinda debate about this, just to see what ideas would pop up. How about having it as a separate panel, setup sorta like a pallette thingy in some of the drawing program. You have the extra-fields panel "stick" to the side of the matching approval window, so the extra-fields panel is at a fixed location wrt the approval window it's related to. Another option is to base it on the key window (sort of the inspectors approach in Workspace). While you may have many approval windows on the screen, there would only be one extra-fields panel, and the contents of that panel would depend on which approval window was the key (or most-recently-key) window. The third option would be to have it like a multi-panel preferences panel. Display the from, subject, and reply-to fields at the top (always). Probably have a row of buttons under that, if it's like a Send window in Mail. Under that, have the text field *-OR-* a form with all the extra fields in it. Use a pop-up menu, a button, or a check-box control to switch between the two forms. Well, actually, that's not too much different than what you started out with, if you change that option to keep the text-field area visible. The difference is that you'd use a button to make the extra fields appear or disappear, instead of using an adjustable split view. -- Garance Alistair Drosehn = gad@eclipse.its.rpi.edu ITS Systems Programmer (handles NeXT-type mail) Rensselaer Polytechnic Institute; Troy NY USA

You have the extra-fields I think this is the way Mail.app works now, and its confusing. Although Mail.app doesn't "attach" the panel to the window.

Now this one was also suggested in E-Mail by Greg@afs.com. I have to say I should have been able to figure out that what I am talking about is basically a swapping view situation. But it doesn't give me the option of viewing all the information at once, where a "collapsable view" would. There was one other suggestion, and that was to put all the TextFields into a Scrollview.

I still haven't really decided on the way to go. greg@afs.com offered a couple of his objects from the afskit to implement it, but since this is going into the comp.sys.next.announce Approval software, I really wanted to try and keep to objects that are available to all.

Changing the color of an existing image. 2. Providing an offset for the image (so it would draw about the center, instead of the lower left hand corner). Thanks to everyone who sent me suggestions. On the first item: Problem solved. I finally figured it out this morning: I create a new Image that is the same size as my existing image, use NXRect to fill a rectangle of the desired color. I then lockFocus on the image I want to change, and composite the first image over it, using NX_SIN. It works like a charm, as long as I have everything I want to change color in a solid, and the background in a clear color. Pretty neat. So that got me thinking: If I can lockFocus on an area of the cache window that holds the image, can I send that view a message telling it to offset itself? I obviously don't know enough about how the imaging works, so I am asking if you all think it is plausible. Unfortunately, I can't just offset the view I am drawing to.

When I do this, if the Kit "discovers" that the appIcon delegate is not actually connected, then it resets it. A view of some kind over the icon is safer. b. When I place a transparent view over the appIcon, then I get the phenomena that the app will work if I launch it from gdb or from a shell: gdb MyApp.app/MyApp MyApp.app/MyApp but NOT if I double-click it or use "open".

If you want to totally change the > implementation details of an object it's better to rewrite it. Even this I just want to clarify a point. When I say "totally change the implementation details of the object", I am speaking of the _provided_ object. Let me explain... If I write a (non-ui) calculator object and give it to you, I would call the calculator a provided object. You can then do with it what you like...use it as is...subclass it to extend it...throw it away:-), etc. Like all other objects, this calculator object provides an interface for you to use: -add, -multiply, -integrate, etc. I should be able to totally change the way I implement the provided object, e.g. change the way -integrate does it's stuff, without affecting the user (who in this case is a developer) of this provided object. The interface to the method (how the user interacts with the method and the end result of the method) should not change. The implementation (the gory details of how I do integration in code) may change. If you take my provided object and redefine a method, bad things might happen in the future. If my new implementation of -integrate (in the provided object) has a new feature, e.g. dropping information on a stack for UNDO support, you're old redefinition of -integrate will not include that information. You'll need to change your object to include it. In the _worst_ case, if -integrate is part of a shlib (shared library), and I upgrade the shlib to include this new implementation, the application you wrote using your old redefinition might crash with the new shlib. In the not so worst case, your application may not include some new feature I added (e.g. the fax feature that was added to all new apps in 2.0).

Johnson) Subject: another shared library problem Message-ID: <1993Aug13.011801.23288@pixar.com> Sender: news@pixar.com (Usenet Newsmaster) Organization: Pixar -- Point Richmond, California Date: Fri, 13 Aug 1993 01:18:01 GMT Here's a good example of something which has no good solution right now; only because NeXT won't let us make our own shared libraries. Let's say you write some code that you're putting in a bundle. Let's say that code uses some library (like, oh I don't know, tcl?). Fine, so you link the library in. Load the bundle into your app, everything works fine. Let's say you write some other bundle that gets loaded into the same program. This bundle also uses the same library the first bundle. You can't link the library into this bundle too, because either nasty things will happen or it won't load (multiple definitions). So what do you do? Well, if it's InterfaceBuilder and the bundles are palettes, you can specify the order of loading, so you make sure that the first bundle is always loaded before the second. Fine, kind of a kludge, but at least you can make it work reliably. But what about a program (oh, I don't know, maybe Workspace Manager) where you can't control the order of loading? Let's say you have two WorkSpace Inspectors that both use the same library. You have to make the decision beforehand which one to link the library with, because you can't do both. That means that a user has to cmd-2 (Contents Inspect) some file of the first type before the second (or third, or fourth, etc.) or it won't work. Worse than that, depending on the order things happen, you can kill the Workspace Manager. If I could make a shared library of the library that they all share, this would not be an issue. As far as I can see, if everybody does what NeXT wants them to (move towards making apps frameworks that load bundles in), a programmer is forced to do all sorts of weird kludges if they want to use their own libraries with their objects. NeXT, are you listening? Am I all wet, or I am just the only one trying to do this stuff? (I would happy to be wrong here, folks...) -- --> Michael B.

I haven't tried it before, but it should work... What happens if you wrap all the TCL symbols in a fake class and use explicit bundle preloading in the palettes? Create a bunch of unreferenced symbols in the class-source and link it against the `TCL' bundle. (or, isn't there a linker option for keeping all the non-unresolved library symbols?) That way the library wouldn't have to be touched and there would still be the advantages of dynamic linking -- without the `multiple defines'. Still, I agree with you, seeing as that it would relatively easy for NeXT to provide the tools. It's an example, perhaps, of NeXT being to religious about the `right approach'. If they would just provide both and a explain the tradeoffs, they'd satisfy and/or impress more people.

I've first written a program which handles the Postscript image properly and reads in the image from a file on disk. The first few lines of this program are stream = NXMapFile("/data/jan/test.eps", NX_READONLY); anImage = [[NXImage alloc] initFromStream:stream]; NXClose(stream); This works fine so I tried to change the program's input stream from reading from disk to reading from stdin (pipe) with the following lines fileDescriptor = fileno(stdin); stream = NXOpenFile(fileDescriptor, NX_READONLY); anImage = [[NXImage alloc] initFromStream:stream]; NXClose(stream); close(fileDescriptor); This program doesn't work so I tried to write the input from the pipe to a temporary file and then read this temporary file into a stream (this is maybe a better way of programming) /* reading from stdin and writing to disk */ fileDescriptor = fileno(stdin); stream = NXOpenFile(fileDescriptor, NX_READONLY); strcpy(tmpfile, "/tmp/EPSviewxxxxxx.eps"); NXGetTempFilename(tmpfile, 12); temporary = fopen(tmpfile, "w"); while (ch != EOF){ ch = NXGetc(stream); fputc(ch, temporary); } fclose(temporary); /* reading from disk */ stream = NXMapFile("/data/jan/test.eps", NX_READONLY); anImage = [[NXImage alloc] initFromStream:stream]; NXClose(stream); But this still doesn't work. The temporary file on /tmp can be read with preview, so it is properly written to disk. I don't know what I'm doing wrong here. Can anybody help me out of this problem?

Date: 13 Aug 1993 16:22:28 GMT Organization: Center for Computer Music Research and Composition, U.C.S.B. Message-ID: <24gf44$4ct@hub.ucsb.edu> I admit to being a novice NextStep programmer, though I have coded in C and C++ for some time. Some aspects of the Interface Builder still elude me... I am working on a fairly simple app -- one window filled with text forms, buttons, and a few sliders, and one custom object which coordinates all of these and has them all as outlets. The custom object is connected as the delegate of the File Owner, and I initialize most of the text form's values in a routine called by appDidInit:sender. This is getting called correctly, but at the time that I wish to set the values of various forms, I find (by using gdb) that about a third of the outlets are still NULL: gdb) bt #0 -[PvocDelegate resetWindow] (self=0xc1580, _cmd=0x8633) at PvocDelegate.m:34 #1 0x45ee in -[PvocDelegate resetToDefaults:] (self=0xc1580, _cmd=0x863f, sender=0xb1668) at PvocDelegate.m:29 #2 0x45a2 in -[PvocDelegate appDidInit:] (self=0xc1580, _cmd=0x61880fe, sender=0xb1668) at PvocDelegate.m:21 #3 0x602fcfc in -[Application run] () #4 0x4a46 in main (argc=1, argv=0x3fffbcc) at PV_main.m:11 Breakpoint 1, -[PvocDelegate resetWindow] (self=0xc1580, _cmd=0x8633) at PvocDelegate.m:34 p *self $1 = { isa = 0x8000, analWindowSize = 0x0, decimFactor = 0x0, endFilter = 0x0, endFilterSlider = 0xb9a34, filterType = 0xb9080, fundFrequency = 0x0, inputChannels = 0xb815c, inputDuration = 0xb80ec, inputFile = 0xb7e7c, inputSampleRate = 0xb7860, inputSkip = 0xb8084, interpFactor = 0xb9de8, numberOfFilters = 0xb7940, outputFile = 0xb85e0, outputFormat = 0xb6b0c, outputSkip = 0xb8430, overlapFactor = 0x0, pitchScaleFactor = 0x0, processMode = 0x0, resynthesizeChannels = 0xb8d10, startFilter = 0x0, startFilterSlider = 0xb94bc, synthWindowSize = 0x0, timeScaleFactor = 0xb9e54, } It was my understanding that these outlets would all be set to point to their appropriate objects (the forms, buttons, and sliders) prior to this function call. Why would some of them be and some not? And YES, ALL OF THEM ARE CONNECTED PROPERLY VIA <control>-dragging. I redid every one of them to make sure. Now, obviously I AM doing something wrong.

This actually has been my most frequent installation problem Are you refering to GNU autoconf? That pile of rubbish has *never* worked right with NeXTs. (Admittedly, it's in some ways a lot less braindead than some of the configure scripts I've seen...) The new posix headers don't trick just GNU autoconf into believing that posix functions are available just because they are defined in the system headers. I've never been a great believer in auto configuration -- for an experienced user it is almost always more trouble than doing the configuration by hand (with a reasonably documented makefile and configuration header). For a good example, just look at procmail. In a few minutes anybody could configure procmail 2.70 to work on a NeXT just fine. Then the author had the clever idea to add auto configuration which makes installation such a hassle that I -- for one -- have stopped upgrading procmail. Better auto configuration schemes just detect the OS and use canned configuration files for the OS in question (and ask the user to do the configuration himself if there is no canned configuration for the particular OS).

This is basically how the Color Digital Eye works. The user boots the DSP to begin capture and the data is sent to the DSP and then transfered to memory. You should be able to use your card, provided that you have the right interface with the port you are using and the right software (in the case of the DSP port, you would need to write the assembly code). -- christopher c hallstrom corbin@reed.edu Can you use them ol' U.S. Blues?

After some experimentation, I've had success stripping the palette with the -u option of strip(1). The following addition to your Makefile.postamble in your palette project directory will do this: all:: $(STRIP) -u $(PRODUCT_ROOT)/$(NAME) I'm curious if this does something evil. I've had no problems with IB rld()'ing palettes stripped like this; someone please correct me if I'm overlooking something.

That's a joke! I have posted this to advocacy because a lot of intelligent people hang out there :-) It seems to me that NeXT are slowly giving us the tools we require. However, most of us still use CVS for revision control. Here's some correspondance I have sent a CVS user. I hope it generates some discussion as to what is required by developers in order to have a worthwhile and usual revision control system. I'm no expert with CVS but I think there's potential to leverage of what it currently provides. Basic CVS comments Also, suppose you create a real cool view class in your production tree/repository however, this view class is something you would like to maintain in your classes repository in CVS. is there any way you can "cvs add" to a specific repository rather and having to check out the classes area, copying your new copy in there and performing a "cvs commit" that way. Related to this is this one. It seems you have to resort to redunancy if your production tree uses library code/classes. ie. when you import you will be copying your library code instead of linking it to the library repository in cvs. ie. you should be able to implicitly checkout the library classes _out of their own area_ that you have defined in your production tree. (What do you think?) Assuming you don't wish to make custom modifications to those classes perhaps it's a fair point? I think this is leading to that ultimate configuration which needs to be totally integrated into Project Builder for it to be of any use. if you could tag your files in PB such that PB knows the repository to find said files then everything could be performed thru PB. or perhaps CVS needs to be able to link files b/w repositorys and that it's CVS's job to checkout the files and PB still works with the files in their local area. There still needs to be data detailing which files are linked to which repositorys so that things can be checked in properly. This is all based on a centralized model and perhaps that's not appropriate. I'd lean towards keeping PB independent of any version control perhaps and just extending CVS so that it provides the functionallity I'm looking for. I have changed my mind several times in this piece since I'm only brainstorming. This all might be way off base but I'm hoping it will generate some worthwhile discussion that NeXT sees.

That's a joke! Message-ID: <24ls8u$r1@steffi.demon.co.uk> An app can contain many things including a ordinary C library. You can build C libraries thru Project Builder however, it doesn't have a recognized "library" project type together with it's own library.make so each time you save in PB using Application as your project type. You get the following lines added to your Makefile which don't relate to libraries. Not to mean NAME.nib as an interface. MFILES = StringFuncs_main.m ICONSECTIONS = -sectcreate __ICON app /usr/lib/NextStep/Workspace.app/applicati on.tiff Thus my compile of a library goes something like this robert:/robert/Programming/NextStep/StringFuncs>make cc -I. -g -O -Wall -I./sym -arch m68k -I. -c StringFuncs_main.m -o ./m68k_obj/StringFuncs_main.o cc -I. -g -O -Wall -I./sym -arch m68k -ObjC -sectcreate __ICON __header StringFuncs.iconheader -segprot __ICON r r -sectcreate __ICON app /usr/lib/NextStep/Workspace.app/application.tiff -o StringFuncs.app/StringFuncs m68k_obj/StringFuncs_main.o -lMedia_s -lNeXT_s clearly not what I expect in a library. So what's the answer? Has anybody devised a library.make that I can use instead of app.make? No doubt MAKEFILE will change each time I save in PB so this behaviour must be included in PB. In fact the obvious solution is to make everything dynamic. ie. produce specifications that PB's uses to save information into the Makefile and determine available project types from the *.make files that exist in MAKEFILEDIR then I could simply add my own project type easily in PB. Can I get away with Bundle or Palette types perhaps? I don't think so as they too have their own assumptions/definitions. I know its easy to build libraries from the command line and hack up the makefiles myself but there should be no reason why I should not be able to do it from PB. Providing PB was made aware of things. Any thoughts?

Riedel The problem are the NXImage object and limitations in the window server. Windows couldn't be larger as 10000x10000. Last month, i've had the same problem. I solved it by using my own image objects. My code is limited to planar b&w TIFF's, but if you want, you can hack in your own code for loading non-planar Files. I used Sam Lefflers tiff library to load the Files into an structure similar to NXBitmapImageRep. I draw them by copying out a rectangle sized and positioned by a docview in a ScrollView. The docview has the same size as the image. When i scoll, the 'visible' portion of the docview changes and during the drawSelf method of the docview, i draw the underlying image portion by 1) copying out the image rectangle 2) draw the copy using NXDrawBitmap If there is interesting, i can upload the code to ftp.informatik.uni-muenchen.de. But at your own risk, the code isn't well documented. It's my first appkit hack and maybe a little confused.

I believe that NEXTSTEP imposes a 32K x 32K maximum size on any window. Since NXImage uses an offscreen window to cache its image, this is not too terribly surprising. -- ................................................................simson

But when I try to retrieve the contents programmatically using getValueForName:"comments": where getValueForName is the following method - getValueForName:(const char *)fieldName at:(unsigned)index { id aProp; id aVal = [[DBValue alloc] init]; aProp = [[currFetchGroup entity] propertyNamed:fieldName]; [[currFetchGroup recordList] getValue:aVal forProperty:aProp at:index]; return aVal; } aVal's stringValue is 0x0 (gdb reports that [aVal isNull] == NO, its typeValue is "*") even when I can see text in the view which is wired to this record's field. By the way, the same method applied to a varchar(255) field of the same record gets its stringValue, so I suspect that the problem is lies with dbkit unable to extract strings from a Sybase text field.

What exactly is the > procedure you use to overcome this problem? There are two parts to my answer. First, the problem of CVS directories getting deleted from a nib when you make a change in IB and save it. Art Isbell (isbell@cats.ucsc.edu) wrote a Makefile.postamble which we have incorporated into our projects. It provides a couple of extra make targets. You run 'make ckout' right after you've done a 'cvs checkout' or 'cvs update' to create a tar archive of all the CVS directories within your project. You run 'make ckin' right before a 'cvs commit' and it uses that tar archive to repopulate your nibs with the CVS directories that were lost when you made nib changes and saved them. As an alternative to this, Robert Thille (robert@ictv.com) has written a palette object which actually preserves the CVS directories right in the nibs. I haven't had a chance to try it out here yet, but I intend to; I understand it works great, and it will eliminate the need to remember to do the two extra 'make ckout' and 'make ckin' steps at the right time. Second, the problem of resolving conflicts in data.nib files. There isn't really a good solution for this yet, but what we're doing to get by is to store our data.nibs as uuencoded files in the CVS repository. When we do a checkout or update, we run through and uudecode all of them so we can work on them, and before we do a commit we uuencode them for the repository. The uuencoding doesn't prevent nib conflicts from happening, it just makes recovery easier. The drawback is that this makes for two _more_ manual steps to have to remember to do at the right times. Another gentleman on the net has extended Robert Thille's palette object to to the uuencoding automatically whenever you save your nib (the uudecoding is still a hitch). If you need more info, let me know...

To the many who voiced the concern that the optimizer was eating the variables missing in gdb: I don't usually use the optimizer. I was inspired to try it, though, after the first response which mentioned it, and discovered that it 'fixes' the problem! I distilled the program in question down by removing everything that could be removed without fixing the problem. I am posting the results. I would appreciate it if someone could try compiling it under 3.0 (without the optimizer) and email me the results. Here it is: /* * This program blows. */ #import <stdio.h> #import <stdlib.h> #define FFT_SIZE 2048 void main() { float x[FFT_SIZE],c[FFT_SIZE],zero[FFT_SIZE]; float WRe[FFT_SIZE/2],WIm[FFT_SIZE/2]; int n,M,N,*samples; M=100; for(N=0;N<100;N++) { samples=(int *)calloc(M,sizeof(int)); for(n=0;n<M;n++) samples[n]=0; cfree(samples); } } It runs without error on the HP. I have been advised that it also runs without error under 3.1. It generates a bus error (or seg. fault if M is changed) when run on my machine under 3.0. Note the the program isn't supposed to do anything, so if it works, nothing happens. Note also that there are several unused variables; removing (or even shrinking them sufficiently) will remove the error. Removing any of the lines and/or changing the dynamic allocation to static also 'fix' the code. If you can spot a programming error, tell me about it. If you know why this code fails please email me! If it doesn't fail (under 3.0) then it seems very likely that my compiler is corrupted, and I guess I'll have to try to find and install a new one...

In particular, a reproducible gcc-crash occurs in the appended program. The trigger appears to be when you want to treat the value in a (global variable) data register as a pointer. It only shows up in this particular program when compiling optimized; compiling unoptimized causes a regular call to be made to gvec_read(), so the fact that it's arg is from a data reg is not a problem. I also know this is a non-problem on a SPARC, presumably because it has fully general purpose register values. Sadly, I don't know enough about the workings of gcc to track down a possible fix. I can use address regs for now, but they are scarce on an m68k, so I'd rather not.

Basically, you create a bundle project, include my files in your Makefile.preamble and Makefile.postamble, and it just works.

The fellow before me is the only person that has worked on this program. I was able to start about 3 weeks before he left, and I picked up a lot in the time that he was here, but now I'm on my own. What I need for now is to find out how to draw in a temporary image, and then display after the drawing is done. What I am doing now is connecting points to make a map. Whenever I scroll, the map has to redraw itself, and it is tremendously slow. What I am thinking is that I can draw it in a temp. NXImage, and then composite the image whenever I scroll. I've also read that a userpath can be helpful. (I'm connecting several hundred/thousand points). I feel like I kinda know what to do , but I'd be greatful if someone would kinda walk me through it.

Well, it's probably a kludge, but in my case, where I write a lot of IB palettes that I also want as linkable libraries, I just add a "lib" and "libdebug" target to my Makefile.postamble (with the appropriate incantations to include the .o's I want), and then add those as possible targets under Preferences in PB. Actually, for my stuff, "lib" is the default target that comes up in PB ('cause I want it that way) which builds the IB palettes, builds a library, and installs the palette, the library, and the appropriate header files in the appropriate place.

I just tried this for two WorkSpace inspectors I wrote that both use tcl (and a couple other libraries I wrote), and it works!

It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. comp.sys.next.hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi.

This is primarily a forum for advanced technical material.

Definately isn't efficient. Actually, you have the basic idea. To make it efficient, you can use getWidthOf: (Font) instead of PSstringwidth(). Since you're going to do this repeatedly, grab a pointer to its method implementation: float (*getWidthOf)(id, SEL, const char *); getWidthOf=(float (*)(id, SEL, const char *)) [Font instanceMethodFor:@selector(getWidthOf:)]; -or- getWidthOf=(float (*)(id, SEL, const char *)) [fontObj methodFor:@selector(getWidthOf:)]; Then call (*getWidthOf)(fontObj, @selector(getWidthOf:), yourString) to see if it fits; if so, you're home free. If not, make a copy of the string with NXCopyStringBuffer() or NXCopyStringBufferFromZone(), and replace its final character with an ellipsis ('\274'). See if that fits. If not, replace that with '\0' and the character before that with an ellipsis. Repeat until it fits or you're left with nothing but a single NUL-terminated ellipsis. Show what you have and free the copied string. Extra credit: redisplay properly when the column is resized. -=EPS=-

Did I say "since he only throws..." or "even if he always throws..."? The contents in his posts are greatly appreciated. It's the stuff around it thats bugs me. And I let it be known, as others do. BTW, what exactly is "that much sh*t"? (As in "[hasn't] thrown that much sh*t") A car-load? A truck-load? A plane load? Enough to smell it from a continent away? I'm wondering here... Besides, I'm referring to stuff he posted prior to the "second-class citizen" comment. That's wasn't bad, actually, as it happened during an actual debate. I refer to answers he gave to questions posted by people who don't know as much as he does, and may be new to NS. Their first contact with the community may end up being with some of his vitriolic posts. That is neither good for NS nor NeXT nor this community, in my opinion.

I was complaining about the bandwidth used without realizing that the bandwidth was being used for illegal, as well as stupid, purposes. I only mentioned NeXT in a passing remark.

I apologized for my post, and that was one of the the explanations I gave for the mistake. It was a mistake I took full blame for.

I've seen a lot of postings from people along the lines of "Help! I can't get <x> to work in order to install NEXTSTEP!". Naturally most of what you hear are problems; satisfied customers don't usually post. I just got an Intel GX Professional (are a lot of these selling?) and it is very fast! I basically didn't want to deal with the headaches of being on my own about installation and problems (Dealer: "NEXTSTEP? Wuzzat?"). I bought it from Alpine Computing Microage and it the experience was great! Much like getting a NeXT machine - I called and ordered from a person who was knowledgable about what the requirements for NS were, the machine showed up, I plugged it and it booted into NS! The only problem was that Intel shipped a bad board. The person I was working with, Kris Magnusson, called their Tech Support and got a board FedExed to me the next day. I hope that this message helps those people who've been considering NEXTSTEP and were confused (like me) by the dizzying array of options available. I really didn't want to spec out a system with no help and have to install it myself (plus I didn't have a CD-ROM drive!). I've had *awesome* service and support from Kris (Alpine has a group dedicated to NEXTSTEP and Unix systems) and I think that anyone who is considering getting a PC to run NS should consider calling Kris. He really bent over backwards to make sure I was satisfied. They deal in much more than Intel GX's, also. No headaches!

Certainly, don't store away the metrics for use with the same face at a different point size. A single font instance may have linearly scalable widths, but if a font is a Multiple Master font with an optical scale axis, those widths may change slightly from point-size to point-size. So don't store the widths, change point size, and expect those widths to always work. (The example is correct, however.) Personally, I'd stick with getWidthOf.

Encapsulation means that _programmers_ who use my class should not have to know anything about my class's internals to use it properly. _All_ methods are encapsulated at runtime - you have no choice but to either use them as they are or override them 100%. Ivars at runtime are not so encapsulated, but as far as I'm concerned they should be because ivars are purely an implementation matter. The fact that the compiler needs them in the interface section to build structures for subclasses is, IMHO, poor compiler design. As long as you don't write code that is dependent on the particular implementation of the superclass, you're correct. Otherwise you're violating encapsulation, which is setting yourself up for danger if the superclass implementation changes. However, even if you override a method by duplicating the superclass implementation of the method and making adjustments (for efficiency, to improve "bogus code", or whatever), the chances are your method will not break even if the superclass implementation changes, unless the internal workings of your method depends on internal details of either other superclass methods or your own methods. Encapsulation also means that no method makes assumptions about the internals of even the other methods in the same class. In the end, though, it's a practical matter of having to know superclass implementation details to write a subclass with minimum time and effort. So I agree that having the superclass source can help in the way you describe, but preventing yourself from introducing dependencies on a particuar implementation is quite difficult. Even more so when you have source. Michael -- Michael Pizolato gnihtyreve noitseuq michael_pizolato@afs.com NeXTMail appreciated

I would name all of those who helped but I got 42 responses!!! There was some interesting responses, and some very useful insight (crt === C run time), the -l in my error message is a library call. My original problem was that Project Builder could not find crt0.o. This happenned because PB did not install all the necessary files (The installation process is farely simple, just press install.). I know because I had to manually copy them and make all of the links. Once that was done, it worked farely simple, except that I got an occasional error saying that PB was looking for Media_s and NeXT_s. This occurred twice, and then it went away and I did not think much of it. By going away I mean that when I built my program, I no longer got that message. I had not made any changes except that I threw away the .app file and rebuilt. I got a program off of the I-net and i wanted to make a few modifications. I immediately got the same error message which as follows: Copied GIFology.nib cc -g -O -Wall -I./sym -arch m68k -I. -c Gif.m -o ./m68k_obj/Gif.o cc -g -O -Wall -I./sym -arch m68k -I. -c gif_main.m -o ./m68k_obj/gif_main.o cc -g -O -Wall -I./sym -arch m68k -ObjC -sectcreate __ICON __header gif.iconheader -segprot __ICON r r -sectcreate __ICON app icon.tiff -o gif.app/gif m68k_obj/Gif.o m68k_obj/gif_main.o GifDecode.o -lMedia_s -lNeXT_s ld: Can't locate file for: -lMedia_s *** Exit 1 Stop. *** Exit 1 Stop.

I disagree with this whole discussion. First of all, neither of these suggestions deals with the issue of how to scroll the text cleanly to the left, since we're assuming it's longer than the field. If the width of the field is not an even multiple of the font metrics, you just end up with a broken character on the left instead of the right.

Either I'm asking things nobody else is interested in, or things people don't know themselves. Boo hoo! For the record, below is a pswrap showing how to test built-in Postscript interpolation. I came up with this after a few days trial and error. Unfortunately, it appears the /Interpolate switch is not yet implemented in Display Postscript for NEXTSTEP; it had no effect for me. Can anyone confirm this? (Scott, Ali?) If this is indeed the case, it's too bad. It makes all sorts of potential anti-aliased imaging applications more cumbersome and costly. I seem to remember a thread a while back in which a few people mentioned they had written anti-aliased PostScript previewers. Were these done by drawing in a larger window, perhaps 4x larger, and manually interpolating down the bitmap (i.e. is that the best, most memory-efficient way without /Interpolate)? Anyway, here's the pswrap: defineps PSsmoothscale(float dstX, dstY, dstW, dstH, srcW, srcH; userobject g; boolean f) /DeviceRGB setcolorspace dstX dstY translate dstW dstH scale << /ImageType 2 /XOrigin 0 /YOrigin 0 /Width srcW /Height srcH /ImageMatrix [srcW 0 0 srcH 0 0] /DataSource g /Interpolate f >> image endps If anyone is interested in a full project to demonstrate this, e-mail me.

OK, the closest thing that I can think of that will be on most people's NeXTs is Mail.app. The field that indicates the author of the message that is sitting in your mailbox. If its too long, Mail.app just hacks it off at the next shortest letter. There is no indicator of their being anything more in the field. Its not editable, so being able to scroll to the right doesn't seem applicable. EPS's suggestion of shortening it and then sticking an ellipses at the end is that I ended up doing. The column looks much better than it did before.

[NXApp hostname] hostName - (const char *)hostName Returns the name of the host machine on which the Window Server that serves the Application object is running. This method returns the name that was passed to the receiving Application object through the NXHost default; this name is set either from its value in the defaults database or by providing a value for NXHost through the command line.

I've been playing with IB to see if there is some way to add new template types (in addition to `Application', `Modules' et. all). I figured I could use appkit's openFile to load a template (say /NextDeveloper/Apps/InterfaceBuilder.app/English.lproj/NewApplication.nib), for starters. Then do something gruesome to rename it back to UNTITLED. AppInspector reports `untitled' and `file'/`dir' instance variables in the (internal) IBDocument class. Reassigning them using runtime functions does cause later Saves to use the new values, but the File Window, etc. are not updated. With some hacking, I could probably get that to work, but it'd be really fragile. Also, I notice the IBDocument class has methods that are surely What I Want (initFromPath:) but exploiting those looks as though it would require several levels of undocumented sneakiness. Has anyone been so bold, er. stupid? As usual, I'm sure I'm just trying way too hard. No doubt there is a clean API way to do this. At this point I think I'll use the methods used in the IB.nib's main-menu to load the template, create a blank template, then use the IBDocuments protocol methods to copy everything, then zap the old one.. If there is a good way to do this, might there be a similar approach to adding project types to PB?

If you're looking for a >general shared memory model like System V has, you're looking at >the wrong operating system. Well, this isn't the whole story. Mach is in fact capable of much more powerful memory sharing then the usual System V shmem interface. Some indication of what is possible can be found in the Book `Programming under Mach' by Boykin et al. Chapter 9 in that book describes External Memory Managment. The example built in that chapter implements secure and distributed memory. It seems to me not too difficult to construct a server that implements full SysV shared memory. This is in fact a project I'm currently working on (but don't hold Your breath). The key system call used here is vm_map, on the client side. There is also an undocumented system call mmap(), used to map files to memory. If two processes map the same file, they get shared memory. There is an implementation of part of the SysV shmem interface using this call. It works, but is of limited use without semaphores. The original poster mentionned semaphores, but nothing like this is available on the NeXT. However, it is possible to write a Mach server that implements most of the semaphore system calls of System V. I actually have written such a server, but it is still in an early version: semget and semop work, the simpler semctl calls also (they don't check permissions so far, but that's a simple addition). What is missing is correct behavior when a process gets a signal during a semop or exits (some hooks for this are already in the code, basically semadj has to be added). Perhaps someone with more experience with the EMM interace could help us build a Sys V shmem library?

I am going to set up an internet service, a la 'archie' that will allow consultants and those needing consulting services to come together. Prospective clients will be able to browse resumes and names, and download postscript &| plain-text versions of resumes. The service will also allow for searching on areas of expertise and experience by clients. As well, clients should be able to post jobs, and any interested consultants would automatically recieve e-mail notifying them of the new position available. This service will be extended to non-consulting areas (permanent positions, etc.) as well. If you are interested in participating, please send a resume (if you send PostScript, then please send plain-text as well) and any suggestions you may have for functionality... The service should be up and on-line in a couple of weeks! Stay tuned here for more details... - darcy

Send Mathematica: $NeXTDisplay := "!psfix -epsf > /tmp/something.eps" And after doing the graph (Plot[]) I send Mathematica another line which I got back as soon as the graph was finished and saved to disk. Look at the other thread "reading EPS via a pipe using streams" to see how this is done.

I've seen a lot of postings from people along the lines of "Help! I can't get <x> to work in order to install NEXTSTEP!". Naturally most of what you hear are problems; satisfied customers don't usually post. I just got an Intel GX Professional (are a lot of these selling?) and it is very fast! I basically didn't want to deal with the headaches of being on my own about installation and problems (Dealer: "NEXTSTEP? Wuzzat?"). I bought it from Alpine Computing Microage and it the experience was great! Much like getting a NeXT machine - I called and ordered from a person who was knowledgable about what the requirements for NS were, the machine showed up, I plugged it and it booted into NS! The only problem was that Intel shipped a bad board. The person I was working with, Kris Magnusson, called their Tech Support and got a board FedExed to me the next day. I hope that this message helps those people who've been considering NEXTSTEP and were confused (like me) by the dizzying array of options available. I really didn't want to spec out a system with no help and have to install it myself (plus I didn't have a CD-ROM drive!). I've had *awesome* service and support from Kris (Alpine has a group dedicated to NEXTSTEP and Unix systems) and I think that anyone who is considering getting a PC to run NS should consider calling Kris. He really bent over backwards to make sure I was satisfied. They deal in much more than Intel GX's, also. No headaches! FYI: Alpine Computing Microage Kris Magnusson (801) 268-8877 Disclaimer: I am in no way affiliated with Alpine Computing Microage or Kris Magnusson, I'm just an *extremely* satisfied customer and I wanted to let everyone else in on the action. - Drew -- +--------------------------------+-------------------------------------------+ | Drew Davidson | "Never ask a programmer if he'll have | | Software Guy | another cup of coffee because it's | | First National Bank of Chicago | nobody's damn business how much he's | | drew@fnbc.com (NeXTmail) | already had!" - me | +--------------------------------+-------------------------------------------+

Certainly, don't store away the metrics for use with the same face at a different point size. A single font instance may have linearly scalable widths, but if a font is a Multiple Master font with an optical scale axis, those widths may change slightly from point-size to point-size. So don't store the widths, change point size, and expect those widths to always work. (The example is correct, however.) Personally, I'd stick with getWidthOf.

Message-ID: <1993Aug19.145415.14882@afs.com> Sender: greg@afs.com Date: Thu, 19 Aug 1993 14:54:15 GMT I have secured Nathan Janette's kind permission to take over the FAQ responsibilities for this group. Here's a thumbnail sketch of the twofold strategy I'm pursuing: 1) A master document with an introduction (how does NS differ from other OS and development platforms), list of resources (books, NeXTAnswers, ObjectWare catalog, other online srouces), porting info (available languages, missing headers and functions), top 10 questions, etc. I'm trying to keep this as short as possible, with pointers to... 2) CSNP-REQUEST, a free service we will maintain with the "best of csnp": in-depth articles, book reviews, source code listings for particular problems, etc. The index for CSNP-REQUEST will be reposted monthly at the same time as the FAQ. The entire archive will be ftp-able from somewhere, and we'll have a special alias at afs.com to ask for specific articles. Think of the ways you can get NeXTAnswers, and you have the idea. I've got a working draft of item 1, and I'm collating item 2. I expect to post the first edition of the FAQ on September 1, and we hope to have the automatic mailback system working at that time. It turns out the mail server isn't too difficult if you can read table_of_contents in *.mbox, which we hacked from a posting by Izumi Ohzawa in this group. What comes around goes around! We will be placing the mailback server in the public domain for other organizations that could make use of it. I'm still soliciting suggestions for "top 10 FAQs", and I'll review any material you care to submit for the CSNP-REQUEST archive.

Unfortunately, this means that this PC can no longer be used for its original purpose until the software is ported to NeXTStep. Fortunately, most of this port has been trivial. The challenging part is controlling the data acquisition board. What I need to be able to do is to set and read values from the PC's IO ports. This is done with assembly language calls to inw and outw. When I try to include these calls in a NeXTStep program, I receive the run-time error "Illegal Instruction." I know that the "proper" solution to this problem is to use the driver kit and to reserve those ports for my driver. However, the beta version of the driver kit, as well as the complexities of creating a full driver make me wary of tackling this job. Does anyone out there know of a way to force mach to run a piece of assembly code without any sort of IO port protection? Please post replies or e-mail to hugunin@mtl.mit.edu.

If you're running Black Hardware, check out my class-dump program (currently at release 1.3). Sorry, there's no Intel version. Back to the subject--try this: make a file called Mail.msg containing -openSend; -setTo:(char *)aString; -setSubject:(char *)aString; -setCc:(char *)aString; -setBody:(char *)aString; -deliver; -openSend:(int *)mailWindowNumPtr; -setTo:(char *)aString inWindow:(int)mailWindowNum; -setSubject:(char *)aString inWindow:(int)mailWindowNum; -setCc:(char *)aString inWindow:(int)mailWindowNum; -setBody:(char *)aString inWindow:(int)mailWindowNum; -deliver:(int)mailWindowNum; [Note that the first six methods exist for compatibility with pre-3.0 software only; do not use them in new programs.] Now type msgwrap Mail.msg This will create four additional files. You could use MailSpeaker.[hm] directly in your application, but it's obviously going to be more efficient to call selectorRPC: yourself. You also do not need to declare the Mail Listener's @interface anywhere in your application with that approach. [I don't know what Simson had in mind; I can't see any scenario in which using a category makes sense. In any case, all Listener methods return int (not id)--the (int) is only omitted in msgwrap input.] Also, you're better off looking up "MailSendDemo" with NXPortNameLookup() than NXPortFromName(). Other than that, Simson's example is more or less on track. -=EPS=-

The Intel EtherExpress is a bit faster because it has a larger cache. To get performance in the range of black hardware, one needs an EISA ethernet card (which requires NS 3.2).

Newsgroups: comp.sys.next.programmer From: wave@pixar.com (Michael B. Johnson) Subject: looking for beta-testers for 3D stuff Message-ID: <1993Aug20.071037.1773@pixar.com> Sender: news@pixar.com (Usenet Newsmaster) Organization: Pixar -- Point Richmond, California Date: Fri, 20 Aug 1993 07:10:37 GMT Hi folks. One thing that I've been disappointed with since 3.0 shipped is the dearth of freeware/shareware/exampleware using the 3DKit. We're beginning to see some useful and well done apps using RenderMan running on NeXTSTEP, but I have yet to see a piece of code that I can get the source to that looks interesting, let alone useful. I think one of the big problems is that the 3DKit assumes you know a bit about 3D CG to begin with, and that you "get" RenderMan, which is a non-trivial undertaking. So, since it's never good to whine without a useful suggestion, I've been writing some code this summer that I'd like share with the net. I've written a collection of objects that I'll be using for my PhD thesis ("WavesWorld: a Parallel, Distributed Testbed for Autonomous Animation") that use the 3DKit. Most visible among them is a WWRIBWell, which is a well which you can drag an arbitrary rib file into and get it parsed into a hierarchy of shapes. This allows you to take output from any of the various commercial modelers, both on the NeXT and other platforms (a majority of modelers on Mac/PC/SGI output RIB) and integrate them in a useful manner into your own app. Best of all, this all runs live inside of IB's "test interface" mode, which makes it way cool. All together I've got thirty something classes in the WW3DKit. One of my metrics of usefulness is that you should be able to write a WorkSpace Inspector for slo and .rib files without writing more than a page of code, and you should be able to assemble the whole UI for it inside of IB. I'm not quite ready to send it out for general consumption, as it's not really ready. Most of the gaping holes will be filled in the next week or so, and I would like to get it in the hands of some other folks for feedback and help. Unfortunately, my experience in sending code out to random net-folks looking for feedback has been spotty at best, so I've had to come up another idea. So... Anybody who wants to get involved, send me mail, and I'll send you NeXTMail with an IBPalette containing my 3D stuff in a week or so. If you can't handle NeXTMail, you're not going to be much of a beta tester, so... Anyway, use the palette and give me some feedback. If you give me some useful feedback, I'll send you the source and consider you a bona-fide beta tester. If you play with it for awhile and don't look at it anymore or think it's stupid or send me inane mail, no hard feelings, but I won't send you any more code. I plan to release this stuff sometime in September either way, as that's when I'm back at the MIT Media Lab and they own what I do. I'll probably release the whole thing as a shareware thing, where you can use it for really cheap, or you can send me a slightly bigger check and I'll send you the source.

Organization: Florida International University, Miami Date: Fri, 20 Aug 1993 18:18:33 GMT Message-ID: <CC2LIy.H0o@fiu.edu> Sender: news@fiu.edu (Usenet Administrator) I have a bunch of points that I am connecting with lines in order to draw a picture. There are several groups of lines, and some but not all of them begin and end at the same point, making a closed path(I guess). I was under the impression that _closepath_ and _fill_ would link the beginning of the line to the end of the line and consequently fill the path with whatever color is set, respectively. If I use lineto between the points, I end up with lines (obviously), but it doesn't fill the path. If I use moveto, the fill colors the points, and that is what I end up with -points. In neither case does it connect the first point with the last as I thought _closepath_ would. Anyone know how to connect random (meaning no regular patern) points and fill the area inside those points with a color? Must be pretty simple, but I'm still learning.

Makefile Preambles and Postambles Message-ID: <CC2K73.5tz@pdh.com> Sender: news@pdh.com (USENET News Account) Organization: PDH, Inc. Date: Fri, 20 Aug 1993 17:49:50 GMT Thanks to the net for the help on including Mail directly in an app. MailComposer looks like one good approach and Andy Stone came through with a direct-coded approach. Here's another quick one. Is there a way to get Project Builder to automatically include a Makefile.preamble in a subproject when it is built? The more general problem is getting header files from the parent project to be shared among subprojects. This does not seem to come for free with the regular Makefile included for a subproject. We have placed a Makefile.preamble in our subproject with adds a CFLAGS -I ../ to get the parent directory header files automatically searcbed but we have to add this .preamble manually every time we build a new subproject. I looked in the Project Builder .app directory and found something called Subproject.table which has a line MAKEFILE = "subproj.make" and I assume this tells PB to find subproj.make in the NextDeveloper/Makefiles directory. Is the a comparable line that can be added to the Subproject.table which will get a .preamble added also? If you have another solution for this issue, I wouldn't mind hearing it also. Thanks for the help and I will post a summary if it looks interesting. Jon Rosen

Here is the scenario: Controller object displays a panel with button that allows a user to move back and forth within a flat file database (ala indexing kit). The forward and backwards button are "continuous" buttons. (You hold it down instead of having to keep hitting it). All this is set up in IB. If a certain record cannot be read (because it has been deleted), it brings up an alert panel giving an error. The problem is, the button keeps thinking its being held down and as a result when the alert panel is "OKed" it returns, another error happens, and so on and so on... How do I tell the button that it isn't being held down anymore when it thinks it is? Why does't the button know it isn't being held down when the active window changes to the alert panel? Very strange...any help would be appreciated. John Zollinger slv0y@cc.usu.edu

The obvious problem then would be that the path is all wrong. As long as the bundle is "under" main bundle, use [[NXBundle mainBundle] directory] to get the path to that bundle, rather than hard-coding a path: - loadBundle:sender { char path[MAXPATHLEN+1]; NXBundle *bundle; sprintf(path, "%s/TestBundle.bundle", [[NXBundle mainBundle] directory]); bundle = [[NXBundle alloc] initForDirectory:path]; if (bundle==nil) // for debugging fprintf(stderr, "bundle is nil\n"); if ([bundle getPath:path forResource:"TestBundle1.nib" ofType:NULL]) { [NXApp loadNibFile:path owner:self withNames:NO]; fprintf(stderr, "got path: '%s'\n", path); // debugging } else // for debugging fprintf(stderr, "could not get path\n"); return self; } I also usually give the .nib extension explicitly, and pass NULL as the last parameter, but unless there is a bug in the NXBundle class, this should not be your problem. Also, check that English is in your System Language default (`dread -o System`). Other than that, I cannot see what problem you are having. Christopher J. Kane kane@cs.purdue.edu

No. It's not the *objects* whose impact you're trying to minimize, it's the compiled code that runs them. Every application has its own private PrintPanel object instance. But the compiled *code* for the PrintPanel class is mapped into a single virtual memory page that is shared by all applications. That's the benefit of shared libraries. -- Gregory H.

NeXTSTEP provides a pretty standard BSD face, so getting most UNIX tools up an running is pretty straightforward. Are there any in particular you are looking for? Noteworthy problems at this point: Sun's NFS sources have a broken file-locking mechanism, so NeXT's initial approach was to disable it entirely. I haven't heard anything more encouraging since. Also, if you're looking at the Intel version there are certainly problems with the serial port that are temporary in nature. NeXT has a fixed serial driver that is available on a limited basis with a public release scheduled any day now. However, if you need UUCP / SLIP right NOW, NeXTSTEP will disappoint you for another week or two. Despite the proprietary face, NeXTSTEP works well in a standard UNIX environment, so you can take advantage of NeXT-specific features while not sufferring incompatibility with the rest of the world. On the standards side, a straightforward VT100 terminal emulator and TN3270 come bundled, and wonderful emulations are available for a wide variety of other terminal types. Third-party X-Windows packages allow X apps to run side-by-side with NeXTSTEP and provide development tools necessary to write X apps using a NeXTSTEP machine. Despite internal use of NetInfo, NeXT's work fine with YP or NIS in a networked environment. On the NeXTSTEP side: NetInfo is a GREAT network management system once you take the time to learn and understand it. The whole NeXT windowing system is very elegant, based on a unified imaging model using Display PostScript. Having a sophisticated object-oriented development environment is wonderful if you're lucky enough to be able to target NeXTSTEP for deployment, but it works just as well for prototyping and personal productivity apps. Having Objective-C side by side with ANSI-C and C++ bundled in one package (assuming you buy the development tools) is a godsend. > I would veer away from any OS which is non main-stream. Then stick to DOS / Windows. > It seems NeXT is going out of their way to produce *YET > ANOTHER* flavor of Unix and make it different and incompatible > enough to be dysfunctional. They are simply taking a standard UNIX flavour (BSD), putting it on top of a decent kernel architecture (Mach) and extending it where current technology doesn't provide an adequate solution for a system designed to be used by end users (NetInfo). > I have heard NextStep is great looking and technically > competitive, but in a world where Unix vendors should be and > are trying to come together, NT seems to be following the old > mentality. I predict their failure unless they pull closer to > other Unixes and fast! NT? I assume you mean NeXTSTEP. The "coming together" of other vendors is a dream that will never come true. Sure I agree that there should be commonality at some level, but ALL vendors will try to differentiate themselves with additional functionality. Otherwise, why buy one vendor's product over another? The indistinguishable "common UNIX" will never happen. NeXT has given every indication of adopting standards that prove to be important to their users, not every standard that comes along. Hence, their commitment to POSIX, CORBA and DCE. If COSE actually produces something coherent which the market likes, I would suspect NeXTSTEP would migrate to support it. > Does it support COFF? No. Does it support ELF? I don't think > so. I don't know on either front, so I won't address it.

I agree, so application vendors will port applications to an environment that appeals to their user base. Many of the environments you refer to appeal to a technical and scientific user base, but don't carry so well in a standard business environment. Why does Sun lose so many financial, government and commercial hardware deals to NeXT? Because NeXT provides an ideal end-user environment (I should know, I was part of TWO such major competitions). > And if you are not application driven, then why not consider > Linux? And you said earlier "I would veer away from any OS which is non main-stream" and "Applications make or break the OS".

Any command-line or X application designed to compile on a BSD system should have little or no trouble with a NeXTSTEP based system.

Check again, NeXTSTEP certainly CAN use the X environment, side-by-side with native applications, it just isn't the standard windowing system under NeXTSTEP. > Did they improve on X? Not really. Care to back that up? Full Display PostScript Level II with device-independant color, an object-oriented development toolset, an end-user oriented environment and a MUCH more consistant look and feel (from Print Panels, Font Panels, Save Panels, Color Panels to menu layout and spell checking, NeXTSTEP applications share an incredible degree of commonality, beyond what you see on the Mac or Windows, never mind X which is a hodge-podge of interfaces). > Is it compatible with X? No. Ahem. Read above, again. > Will there be Next Windows Terminals? No. How can you state this for certain? Like X, NeXTSTEP can redirect input / output to another device on the net. Currently this has to be a NeXTSTEP equipped system, but there is no technical reason why a terminal couldn't be designed. There are no such devices available now. However, NeXTSTEP will run on quite inexpensive PC's. > Did they even build on X? No. This just seems very strange. Given their goals, it certainly does not.

Actually, I think they simply feel that the Unix level is not as important as others do. Most users interact with the NS GUI environment, which is where they are putting most of their effort (and of course altering the kernel to support any changes they want to make at the NS GUI level). However, for the most part, the differences between NeXT Unix and any other tend to be more annoying than crippling. I would not call it dysfunctional. > >I have heard NextStep is great looking and technically competitive, but in >a world where Unix vendors should be and are trying to come together, Nt >seems to be following the old mentality. I predict their failure unless >they pull closer to other Unixes and fast! I agree that as a long term goal, NeXT should make their Unix layer conform to whatever the final, final, final version of Unix becomes. I am not as convinced as many others that that Unix is "obviously" this or "obviously" that, and even SVR4 is evolving (not radically, of course). So conforming is not just a simple task in and of itself, given the resources available to Next. Their focus is with their prime technology. The most "great looking" and "technically competitive" portions of NS have little or nothing to do with Unix (the NS environment, IB/PB, object kits, DPS, RenderMan, etc). Your prediction misses the point altogether. NeXT's fate has nothing really to do with the fate of Unix in general. General acceptance of Unix in the business community can help NeXT, but whether there is unity in the Unix community or not changes nothing with NeXT. Most NeXT apps are not as tightly coupled with the Unix API, and those NeXT-specific apps are really what sell NS. Perhaps you think that NeXT's goals are to capture 25% of the Unix market or maybe all of it. If so, yes they will fail, but most people in the NeXT community and I would think most people at NeXT would consider NeXT a success if they simply achieve successes in several niche markets which are capable of supporting the company and fund advances in the technology. It would be great, from my point of view, if NS was free and preloaded on every system on the planet, but the truth of it is that most people don't currently need all that NS provides, and thus shouldn't have to pay for it. However, many either need or can make productive use of NS technology, and those people should have it. I'd consider that an all around success. > >Does it support COFF? No. Does it support ELF? I don't think so. >Who is going to port software to it (especially commercial software), when >there are many other ESTABLISHED OS's to be considered first- SCO, Sun, >V.4.2, DEC, etc... Applications make or break the OS. I'll take the risk of sounding like a serious NeXT bigot and also of potentially being in great disagreement with lots of NeXT users. My own experience is that given the choice, NeXT users don't want *ports* of software, they want NeXT native software that has the same capabilities and works in comparable fashion, with all of the NeXT goodies added in integrated fashion. In otherwords, Wordperfect is nice to have on the NeXT, but but a written-for-NeXT-from-scratch word processor would probably be much nicer. Yes! Applications make or break an OS. People buy NS because 1) You can write your own custom software much, much faster than on any other platform, and in a business setting, that can be worth serious money. Even reducing development time in half can save several hundred thousand dollars, which pays for NeXTstep, extra memory, gargantuan hard drives, cable tv, the porsche, and a heated pool. 2) Commercial shrink wrapped apps tend to be of higher quality than on other platforms, and are nearly always more powerful, by virtue of running in the NS environment, and by virtue of NS freeing the developer to invest the time and effort to increase the power of their apps. People buy Unixware, or Solaris, or even Windows to run the apps that everyone else runs. People buy NS when they want to run better apps than those, or if the app they need doesn't exist anywhere, and they have to write it themselves. Apps sell all OS's, adn NeXT is no exception. > >And if you are not application driven, then why not consider Linux? >It is a lot more mainstream and likely to stay around longer.

I'll ignore the claim of Linux to be mainstream, and in fact I consider Linux to be a worthy and rather successful effort. BUT, NS has been around for a while now, and blithely stating that Linux has a better chance of staying around than NS is not a fair statement. NS defenders will claim the same ground as the Linux supporters, namely that if NeXT were to disappear tomorrow, many NS users would continue to support the platform to keep it going, and furthermore NS has a head start in many technologies which give NS supporters lots of breathing room before NS becomes obsolete, probably years. > >>Which of the environments presents a bigger porting challenge for a >>typical UNIX command-line or x-based application? > >Certainly X.

No. >This just seems very strange. This comparing NS to X is really starting to get under my skin. The COMPONENT of NS roughtly equivalent to X is DPS. The NS GUI is built on DPS, and the environment which coexists with the GUI has additional functionality. There is only one reason for supporting X, and that is to allow the running of X apps. Whether or not the NS GUI is itself built on X is totally irrelevant. And you can get X running on NeXT just like any other Unix platform. So this "compatible with X" thing is a completely vaporous criticism, as is "built with X." Now, why did they not build on X, which the poster thinks is strange. I would say that it is a safe bet that more than 100 times the man hours have gone into making simple X dev tools as have gone into making all of NeXTstep combined. Where is IB/PB for X? Either the NS implementation solves a lot of problems which X cannot, or pretty much everyone working outside of NeXT is a moron. Which of these two are you willing to accept? Now, the terminal argumment is valid. There are no DPS terminals, and there doesn't seem to be any on the horizon. Here, though, you are on somewhat philosophical ground. X terminals are popular now, kind of Wang word processors were popular once. That does not mean they will always be so. I never cared for terminals myself. I would prefer to be working in a client-server network where there is a real CPU on my desk. I understand the cost equations that X terminals solve, but personally I think terminals (X or otherwise) are at best a stopgap solution until the compute needs on the desk outstrip terminal capabilities and compute-power prices drop to the point where it is cost effective to buy general CPUs over terminals. Certainly, even now many business situations call for a CPU on every desk, and in those cases, NS power comes in handy. Put it this way, there is no such thing as a Windows 3.1 terminal, or a Mac Quickdraw terminal, but that does not severely hurt those platforms, because that is not the market they are targetting. The market NS targets happens to be those in which lots of power is desired everywhere; power either to process information or to present it in as human friendly a manner as possible (which also often requires serious crunching). There, terminals are useless, and therefore unneeded.

Fortunately, crystal balls run DOS and are prone to failure. I predict UNIX vendors will come together to stab each other in the back and develop a truly, stupendously mediocre product. > Does it support COFF? No. Does it support ELF?

Applications make or break the OS. Is that number of applications or quality of applications? After all, WordPerfect was ported to NEXTSTEP and it was still crap. Just goes to show that original NEXTSTEP apps are far superior to most ported applications. > And if you are not application driven, then why not consider Linux? > It is a lot more mainstream and likely to stay around longer.

If you're not a UNIX weenie, there's no point in trying. Linux is more mainstream? I thought its advantage was that it had no real UNIX code. That would put it on a level with Coherent (acts like UNIX, but isn't). Could you tell me where I can pick up a copy of SCO with development tools for less than $299 ($249 academic)? Even a non-upgradable release? > Certainly X. Nextstep doesn't even use this standard Unix windowing system. > Did they improve on X? Not really. Is it compatible with X?

The sad part is that I have to teach people to use X and tell them how our X based application is so easy to use.

I gather that UNIXWARE is the more standard UNIX-based architecture, but that many of these tools have not been ported yet. No, all NeXTs run BSD 4.3 which is the standard UNIX architecture. While SysV based systems have been approaching that standard with SysVr4 there are still large areas of incompatibility. What about NeXTSTEP? It's proprietary nature is both a plus and a minus, but if all of the above already exist and are stable there this might not be as big an issue. Not quite. It is only the window system on NeXTs which is proprietary. The underlying operating system is just about as standard as they come. Which of the environments presents a bigger porting challenge for a typical UNIX command-line or x-based application? UNIX command-line tools are as easy to compile on NeXTs as on just about any system on the market and more so than most. X based applications compile reasonably easily with the separately available X servers. Porting X based applications to run on NeXTs natively is a formidable task. Ultimately, if you buy a NeXT you are paying mainly for one of the most powerful, efficient and elegant windowing systems and application development environments available today. If you still need to run an occasional X application or display an X window from another machine, the available servers will do an admirable job for you. But if you intend to run only X programs and completely ignore the NeXTstep world, a NeXT is not the optimal machine for you. Carl Edman

It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. comp.sys.next.hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. comp.sys.next.marketplace NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. comp.sys.next.misc For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! comp.sys.next.programmer Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. comp.sys.next.software This is a place to talk about [third party] software products that run on NEXTSTEP systems. comp.sys.next.sysadmin Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. (The original comp.sys.next no longer exists--do not attempt to post to it.) Exception to the crossposting restrictions: announcements of usenet RFDs or CFVs, when made by the news.announce.newgroups moderator, may be simultaneously crossposted to all c.s.n.* newsgroups.

This is potentially a hairy subject. No matter how much effort you put into making a base platform which is uniform, the value-add stuff can easily itself become enabling technology which, if you build apps which rely on it (because there is no way to do it any other way) then the portablility problem comes up again. >>I don't know on either front, so I won't address it.

Unless, of course, you are already in one of NeXT's stereotypical market segments, in which case no problem. Keep in mind that NeXT did not pick those areas to attack, and make a platform which they thought would suit those markets. They tried to build a platform which appealed to as wide a market as possible, given the technology they wanted to provide, and those markets were those which responded the most strongly. It was only when NeXT saw that that they began to target those markets with more emphasis. > >>> Did they improve on X?

They just didn't improve X. For NeXT end users, improving graphics support would seem to be more important than improving X. If you want X so badly, just get one of the X packages for NS and run X. If you think X isn't good enough, you can spend a lot of time improving it, or use DPS on NS. Which is not to belittle efforts to improve X; it is a laudable effort, but I'm not convinced that it can be improved to the refined point NS is at the moment. > >>> Did they even build on X?

They don't include it with the shipping package, but there are freebee versions of X out there, and there are commercial packages which do not cost a lot on the third party market. That is NeXT's strength. On NS, I can run NS side by side with X. On an X station, or other platform, you can run X, and that's it. As a buyer, that should factor in.

I'm looking for either a my_port-to-its_port translation (or an indication that the target task has no rights), or a mutant version of port_type() where port_name would be expressed in "my" name space. I can (uncomfortably) use port_insert_send() to determine if a task holds send rights, but not which name it uses, and this still tells me nothing about receive rights. (I realize that asking for "task kernel port of the task holding receive rights to a given port" is unreasonable, at least not without having the host privilege port available. This would be really useful, however.) Is there a better way than slamming some code into the target task and starting a new thread? -=EPS=-

From: me@ienext.unl.edu (Dan Scott) Newsgroups: comp.sys.next.programmer Subject: A couple of easy questions Date: 24 Aug 1993 17:37:30 GMT Organization: University of Nebraska--Lincoln Message-ID: <25djkq$t61@crcnis1.unl.edu> Yesterday I was messing around trying to improve my NeXTSTEP programming skills. I have an application with a window that displays several views (they are matrices of TextFields if it matters). The layout of this window had been set up in interface builder. I got to thinking that I might want to modify the size of one of my views in response to a user input. So I used a sizeToFit command in my code. This *did* resize the view as desired, but there was a problem: the old (larger) size of the view was still visible (though partly obscured by the new size). After I thought about it this made some sense---the view was getting a command to display itself again (after its size had changed) but there was never any command to "erase" the picture of itself that it had *previously* drawn. What I did was: 1) Before resizing the view I got its frame rectangle 2) I locked focus on the contentView of the Window (which was the superView of the view I was resizing) 3) I filled the frame rectangle with NX_LTGRAY which is the usual background color of a window. 4) Unlocked focus 5) Displayed my resized view This seemed to work ok. Now, At last the questions: 1) Is this more or less what you have to do in this kind of situation? Or is there some simpler way to see to it that old "outdated" images are not left visible? 2) Originally, when I filled the frame rectangle I didn't bother to specify NX_LTGRAY. I figured that I wanted my erasing job to match the color of the background (the contentView's color). Since I had locked focus on the contentView I assumed that it would draw in the background color unless I specified otherwise. Imagine my surprise when my erasure was done in black! Could it be that the last thing drawn in the contentView of this window was in black? (part of the border??---but that's not part of the contentView, right?) Why didn't this work like I thought it would?

This includes applications you launch under Workspace, and their children, so that if you launch an app from the commandline it will run OK - BUT - it doesn't include applications launched via "rsh". Launching something under rsh means that you wind up with a process that's a child of the "rshd" daemon, which is a child of inetd, which is a child of init (process 1). These processes aren't descendants of Workspace, so they can't connect to the window server, so they can't display on your screen if you don't have PublicWindowServer enabled. Similarly applications that you launch via the crontab won't have access to your screen if PublicWindowServer is off. Certain special programs, such as the thing that writes "Printer out of paper", always have screen access anyway. From "man loginwindow": PublicWindowServer is a parameter indicating whether unrestricted access to the window server on this machine should be allkowed while the user is logged in. If it is YES, then any client on any machine may connect to the window server. Otherwise, only processes descending from the Workspace or special system processes such as the printer daemon will be allowed to connect. I wish I knew what the strict definition of "special system processes" is. Anyway, I know of one program that gets around this by installing a server process as a login hook. When you log in at the console, a loginhook program will be launched and will happen to be a child of workspace, so it can hang around and have access to your screen even if PublicWindowServer is off. You could come up with a way to tell that server process to execute something on your behalf, and it would have access to the screen. Hope this sheds some light.

E.g. Browsers/Matrices being loaded and reloaded several times, inspectors doing lots of updates, controls having their values set to the same thing over and over - this can be far more damaging than an extra setgray here and there. A couple tricks I adopted early on (maybe it was because I had an '030) was to: - override Application so that if updateWindows is called it happens only ONCE for that event. - write a couple categories for Cell and Control which has methods like setFastEnabled, setFastIntValue, etc. etc. These will only set the value if it is changing - otherwise AppKit objects redraw everytime you set the value regardless of whether it changed or not. - for things like matrices/browsers I use a change count for the data they represent - only reload them if the data actually changed. These couple of simple things when adopted early on make inspectors and UI components blazingly fast. Depending on the complexity of the application, optimization may be some thing to consider from the start, spending 5 months on core functionality and then trying to optimize it later will give you more bugs and headaches than if you had started from the beginning with optimization in mind. la la la, -- :: Christopher Lloyd :: Yrrid Incorporated :: lloyd@world.std.com :: :: NEXTSTEP Special Forces ::

There are two things to remember when programming for the Display PostScript System: 1) The model is client server. Stop using single ops. Stop it right now. Don't ping if you don't have to. No, I really mean it. Stop using single ops. :-) 2) It's a *language*. There are three ways of encoding the PostScript to be sent to the server, and it's under application control - the client library will translate for you. Has anyone tried flipping an app their developing to use binary token enoding and *then* trying a SLIP connection? When the pipe is the bottleneck, be gentle on the pipe. Binary encoded PostScript is big - it makes the interpretation speed vs. memory use very far on the speed side. Which is great if you're running on the same machine as the server, and it costs nothing to send gobs of data. Binary *token* encoding makes the exact opposite tradeoff - which is the right thing to do over a slow connection. And the server is always ready to slurp both. There's also always more than one way of doing something. And the best way to do something depends on what your doing. Drawing polygons, you may always want to use moveto/lineto, and avoid special case code. But if you know you're drawing rectangles, use the rect* operators. And if you're going to be drawing *lots* of rectangles, look into the numstring encodings that let you do that with one call. And if they're lots of small rectangles, of a specific number of sizes, think about making a Type 3 font and using xyshow. Like Scott said, RTFPB. Then read the Purple Book again. A lot of experimentation and thought went into that book, for you to take advantage of. Go ahead and spend an extra day to have your application do the pre-clipping based on bounding boxes. Think about what redrawing needs to be done. And when. With these more powerful machines, it's easy to get lazy and not do all the code optimizations that used to be a standard part of writing an app. But there are always going to be situations where that little extra effort would make a critical difference in the useability of an applicaton. -- Scott Byer NeXTMail: byer@mv.us.adobe.com Adobe Systems Incorporated These are *my* opinions, and 1585 Charleston Road, P.O.

Message-ID: <53701@sdcc12.ucsd.edu> Date: 25 Aug 93 17:35:41 GMT Sender: news@sdcc12.ucsd.edu Followup-To: comp.sys.next.programmer Distribution: na Organization: Mathematics @ UCSD I was wondering.... One complaint is that obj-c is slower than C++. For example, -rank {return rank;} is basically a procedure call to return the value of a data field of an object in an object oriented way. In C++, someone would use an inline statement. 1. What about a new directive @inline which would attempt to replace a small function of the type above with an inline function. Since it is only at *attempt*, if the compiler can't resolve the inline command then it doesn't. This allows the programmer to still have the flexibility of objective-c but when the compiler can do better it does. 2. Maybe the compiler should try to do this anyways if it can if an "optimization" flag is set. Also, maybe the compiler could resolve some of the method calls to @selector (or whatever that is -- I am not experienced with objective-c yet) so that there would be a faster run time. Again, if the compiler can't resolve it, then it doesn't. Maybe someone could write a commercial preprocessor? Wouldn't this partially diffuse the static/binding debate in objective-c's favor? If I am all wet, so be it. Mark Stankus

The purpose of that server is to broadcast ASCII messages over the network to clients. One client send a message, all clients, except the sender, receive such a message. To acheive that, the client application encapsulate its message into an object. That object has four (4) outlets: char theMessage[64]; char theSender[64]; int messageType; int refs; The first three outlets are used to encode the message, the last (refs) is used as reference count; my object conforms to the NXReference protocol. The client uses - (oneway)clientToServer:(in id)anObject method to send the messaging object to the server. It receives from the server messages via the -(oneway)serverToClient:(in id)anObject method. In the server, I have the following method: - (oneway)clientToServer:(in id)anObject { int c, nbreElement; mutex_lock(mutexListe); nbreElement = [uneListe count]; mutex_unlock(mutexListe); for (c = 0; c < nbreElement; c++) { mutex_lock(mutexListe); if ([uneListe objectAt:compteur] != self) [[uneListe objectAt:c] serverToClient:anObject]; nbreElement = [uneListe count]; mutex_unlock(mutexListe); } printf("!\n"); } Right now, my server works. Howver, each time a client send a message, I have an exclamation point and a cariage return printed in my Console. If I remove the "printf("!\n");" statement, the server crashes when a client send a message. The "printf("!\n);" acts like a vaccine against server crashes... The problem is that the printf is NOT the solution to my problem and that hides the real problem, sooner or later the "vaccine" will be inoperative and my server will crash again.

Hi all, Im writing a project where I take a whole bunch of amplitudes from a sound file and dump them into an array. Now I believe I need to run an FFT on ths array to break it up into the contributing X number of frequencies. So here is the rub, does anyone have a REAL simple FFT routine that I could use? I'm doing this on a NeXT computer... Does anyone know if its quicker for me to have the DSP do this or just to let the processor do it? I will have to run this FFT every .05 secs so I wonder if its worth the trouble to shoot data over to the DSP? Anyhow thats why I want the code so I can have the CPU do it, but if its faster to have the DSP do it I would appreciate an example of how to use the DSPfftr2() function, giving it my array. Actually I would like the FFT in any case, so the program could run on the Intel machines too... I also noticed the "setFromSamples:" method in the Partials class of the music kit. It takes a samplesObject??? What is this samplesObject??? Can I just pass it a SNDsoundStruct or a sound object with a sound in it??? Or do I just give this method an array of samples??? Does this method even work with sound type or does it work with scoretype sound?? Sorry for the stupid questions, but this is my first project in signal processing. THANKS BIG TIME for all/any help!!! Later, John

After adding at least one view to the list of switch views, when I try to switch the Connections Inspector from the View List Inspector to the Box Inspector, using the Alt-Control-Drag instruction on the Inspector does nothing but open IB Help :-( If I assume that Alt-Click is really meant like for the Attribute Inspector, I get a runtime error: Runtime error: SVConnector : does not recognize selector -label. After dismissing the Alert Panel and clicking on the Inspector panel, the Box Inspector does appear, but this problem hasn't made me anxious to use this in production code when other switch view palettes, although possibly less elegant, work flawlessly. Of course, source code for TTools palette is included, so I guess this bug can be fixed, but releasing a MiniExample that's broken seems a little poor. But I appreciate a buggy MiniExample over none at all, so I'm not really complaining :-) If anyone's patched TTools, please post your patch and save us all from repeating your work.

Hi all, Im writing a project where I take a whole bunch of amplitudes from a sound file and dump them into an array. Now I believe I need to run an FFT on ths array to break it up into the contributing X number of frequencies. Ok, now I have a radix 4 FFT, and thats OK, but what I found out that I need is either a Discrettime FFT or a Continous time FFT (in C of course :) (If you have such a routine and can email it to me that would be a blessing, If you know where I can find such a routine that, too would be a blessing :) I think this takes a 2 dim array with time data and will give me back the frequncies.

I'm going to try and port it, big task I know but I'm bored. The problem: (Those damn header files) Because of the way Ingres was written I am having to use a -traditional as one of the flags to cc (someone declared a variable with the name const). When using -traditional neither gcc nor cc will evaluate the #include macros that NeXT uses in some of their header files. ex: #include ARCH_INCLUDE(bsd/, machparam.h) in the file /NextDeveloper/Headers/bsd/machine/machparam.h I wasn't surprised to find out that gcc wouldn't make the translation. I mean, if your compiling with -traditional you should expect traditional stuff, but when cc didn't work (I know it's based on gcc) I was a little peeved. If NeXT is going to do so much untraditional stuff then they should support it fully. Now, I have been happy with my NeXT from the day I bought it. I understand their reasons for dinking with the headerfiles the way they have, and I don't want to start a debate on whether or not it's right or wrong, but damnit if it ain't frustrating to deal with in the real world.

If this loop *really* infinate or is it just long? If you push the OK button enough, will it eventually end? My guess is that the repeat functionality causes events to be appended to the event queue at givin intervals, and that your processing of the events takes longer that it takes for the next event to be appended. So the solution is to get rid of the extra events. I suggest you do it evertime you process one (this will have the added benefit that when the user lifts the mouse, there it won't keep going.) So how do we get rid of those events? [NXApp getNextEvent: waitFor: threshold: ]; should get them for you, there is even a flag fomewhere in the event to check it the event was a "real" mouse down or a "fake" one.

I don't think the Big-O analysis is applicable to this problem. We know a lot about the domain of this "algorithm" that we can apply to our decision making: 1) We can assume that most of the strings will be perfectly visible and will only require one call. (If not, we need to redesign some of the gui. What use is never being able to read something that is being displayed) 2) It is reasonable to assume that strings will be relatively short. 10 - 30 chars prob'ly, 30 - 100 possible, if it's more than that, why is it on one line? (99.999% sure < 400 chars) 3) The character based computation is likely orders of magnitude faster than the display of the string. (maybe just multiples and not magnitudes) So, with the above considerations I'd say... If you're hacking 'n slashing, or even if you're quickly impolementing a well thought out design, do it the quick and dirty way. If you notice performance problems or, after profiling your finished app, you discover costly routines, then fix them. <donning philosopher's cap> We need to not forget that our time is worth more than a CPU's time or a disk's space. If we strive for the (theoretically) perfect app, we'll end up striving for a long time.

The general rule is that you're not allowed to override procedures in libsys. malloc() is actually one of the few exceptions (yes, there's a trick to it). HOWEVER, software that attempts to provide its own version of malloc() for the hell of it is probably severely misguided. NeXT's malloc() is not the traditional BSD malloc(), and if you think you're going to get better performance with your own version, you're probably wrong.

It depends on what you are porting from.

I've had distributed objects corrupt memory on occasion (this was with NS 3.0, I haven't tried since getting 3.1). After memory is corrupt, the crash seems to occur during the next message from DOs. If you try to check to see if a remote object conforms to a protocol [remote conformsTo:@protocol(something)] Then DOs will corrupt your server (again, in NS3.0). This has something to do with @protocol resolving to an object instance... Anyway, if you've got this then take it out. If not, send me some e-mail with some gdb information that I can see. DOs in 3.0 are more experimental than anything. I wouldn't base a serious program on them, because they are not robust at all, they have lots of confusing elements in them, and there have been reports of memory leakage. Perhaps 3.1 and 3.2 DOs are better. - db > > The "printf("!\n);" acts like a vaccine against server crashes...

This is probably not the best solution for you at this moment, but wait for NS V3.2. I have an AWFULLY good suspicion that RTF source will be at least partially supported in that release, by NeXT. I'm GUESSING that compiles, stepping in gdb "view" mode with Edit, and some other things might work, but maybe IB won't parse RTF headers, and some other things might not work. MAYBE the decision to support RTF was made too close to the release date to hack in full support in time. MAYBE, IF WE DEVELOPERS TELL NeXT THAT WE LIKE IT ENOUGH, they'll decide to support RTF fully in whatever is the next release after V3.2. Of course, I could be wrong about this. What am I basing this suspicion on? Well, I have a little stone Buddha in my basement, and I rubbed his belly, and I heard a mysterious voice...

Date: Thu, 26 Aug 1993 17:49:07 GMT DISTRIBUTED OBJECTS MEMORY LEAK in 3.0 ... still in 3.1! According to Next's documentation space for arguments passed to the server is allocated on the server side, and a pointer to the local data is received. The server's allocated copy of the data is local in scope and WILL BE FREED BY THE SYSTEM WHEN THE SERVER'S METHOD RETURNS. The capitals in the last statement is NOT the way DO has been implemented in 3.0 (and 3.1) I have written a small test program (shown below) to test/confirm this BLATANT memory leak in Distributed Objects. I see the 3.1 Release notes have fixed some bugs in DO, but failed to mention a fix for this bug. COMMENTS This Memory Leak has serious effects on the whole DO concept! It completely annihilates the concept of transparency of the DO paradigm. Without always passing sender, how is one to know if a method call originated locally or remotely? My patch to call free() explicitly would have very nasty effects if it were to be called on data passed locally on the stack. rfschtkt@banruc60.bitnet has added this to the Known Bugs in NEXTSTEP (KBNS.11.1.005_3.00): "Distributed Objects KBNS.11.1.005_3.0o Memory leak, reported by Bradley_Head on NeXT-prog@cpac.washington.edu on 1993-08-24, verified using his test program (available from him and included in the original report) by me IntroDistObjects.rtf says: In both the useAnIntByReference: and useAString: methods, a pointer is dereferenced on the client side, and the resulting data is sent to the server. On the server side, space for the data is allocated, and a pointer to the local data is received. The server's allocated copy of the data is local in scope and will be freed by the system when the server's method returns. This isn't true on 3.0 for strings: the string is leaked in the server. Bradley_Head said that the first string isn't leaked, but I found that it is." I sent this to bug_next. I can't believe NeXT has not fixed this for NS 3.1. TEST_CODE Here's the test code: I call it DOLeakTest_main.m. The instructions fo compiling and testing it are in the comments: /* * DOLeakTest_main.m * * * Distributed Objects memory leak test program. * * To use this program, first compile it like so: * * 1. Create a new project using Project Builder * 2. De-select "Generate Main file on save" option in Attributes. 3. Replace the _main.m file with this one. 4. Add libMallocDebug.a to the project's Libraries. 5. Compile as usual. * * * Alternatively: * * compile like so: * * cc -Wall -g DOLeakTest_main.m -lMallocDebug -o DOLeakTest * * To run the program, start the first one with the FULL path * name in a shell. This becomes the server. * * Select this "server" from the MallocDebug.app and check for * leaks, by clicking the "Leaks" button. It should say "No nodes" * at this point. * * Now, start another one these. It will become a client and ask * for text to send across to the server. Typing 'q' will quit. * This will be the client which will send the argument string over * to the server. At this point, no leaks should present themselves. * The next time you send a string, the previous string will become * the leaked memory. * * Somebody please test this code under NEXSTEP 3.0 and NEXTSTEP 3.1 * to see if this BUG has been fixed under 3.1. * * Thanks. */ #import <objc/objc.h> #import <objc/Object.h> #import <remote/NXProxy.h> #import <remote/NXConnection.h> #import <stdio.h> #import <string.h> #define RO_NAME "leak_test" @protocol ServerProtocol - receiveStr:(const char *)aStr; @end @interface MyServer:Object { } - receiveStr:(const char *)aStr; @end @implementation MyServer:Object - receiveStr:(const char *)aStr; { fprintf(stderr, "Received '%s'\nThis will not be freed when '%s'" "method returns.\nResults in a %lu octet leak the next time" " this method is called.\n\n", aStr, sel_getName(_cmd), (strlen(aStr) +1)); // According to NeXT Developer Docs, General Reference, Chapter 6 // Distributed Objects: // // "On the server side, space for the data is allocated, and a // pointer to the local data is received.

Originator: gregw@isaacs Sender: news@advtech.uswest.com (Radio Free Boulder) Organization: U S WEST Advanced Technologies Date: Thu, 26 Aug 1993 17:32:46 GMT I'm currently developing an X windows application on a Sun workstation. I've been asked to assess the possibility of porting the application to a 486 PC. The application is fairly large - 70000 lines of C++ commented source plus a few sizeable in-house developed libraries, and is based on a client-server model. It is comprised of multiple processes that comminicate using TCP/IP sockets. It must interact with a number of pieces of telecommunications equipment, either co-located on an ethernet LAN or via a modem interface. The application currently relies heavily on Object Design's ObjectStore database and on Wcl (Widget Creation Library). ObjectStore is currently (or soon planned to be) supported on: Windows 3.1, Windows NT, and OS/2. One of the primary aspects of the application is its ability to display data on a geographical map. The geographical maps are stored in ObjectStore and tend to be fairly large (~100 MB each). Porting the software that displays the geographical maps may be impossible, so a PC-based geographical application may be required. One of the reasons for porting to a 486 PC is to minimize hardware configuration costs. Even thought Sun workstations prices keep falling, 486-based systems seem to be a few thousand dollars cheaper. The PC might run the application in stand-alone mode, or as a server with other PCs on the LAN accessing the application remotely. Of course, reducing software license fees is also a priority - it doesn't make much sense to save hardware $ only to pay out bigger run-time fees. So now the question - which software platform should I port to: - Windows 3.1 - Windows NT - OS/2 - Desqview/X - SCO Open Desktop - NextStep - ??? I'm familiar with Windows 3.1, OS/2 and Desqview/X, but I don't know their X-windows and TCP/IP capabilities. Thanks in advance! -- Greg Wilson gregw@uswest.com

The > "in" keyword means "I don't want to change that reference, I just want the value > contained in it". However, you've failed to note that the 'id' type is a special case in distributed objects. The object is vended in one of two ways. The first is as a 'proxy', for which a special mechanism for talking to the remote object is allocated on the local side. For a proxy, 'oneway' does not make sense, since it is always 'oneway'. Also, an object proxy as a method parameter is always 'in', a returned object proxy is always 'out'. Confusin' but: - (oneway out id) methodCall:(oneway in id)obj; is equivalent to - methodCall:obj; Depending on your needs, you can write it either way. I don't like the 'in's though, and this may be just superstition. The second way you can send the object is 'bycopy', in which a copy of the object is sent over the wire. This is implicitly 'in', or 'out' (for method arg or return value respectively) since it does not make sense that the copy of the object you just made should exist at all on the local side. Thus neither 'in' nor 'out' make sense (ie are needed) when an object is a parameter to a method. As well, this is clearly incorrect: - methodCall:(out id)obj; If you assign 'obj', it would go nowhere (What *really* happens then?) This works though: - methodCall:(out id *)obj; Although I'm not sure if DOs can handle this case. This is the only problem with DOs in my opionion... the syntax isn't very robust. > Hum...

Newsgroups: comp.sys.next.programmer From: jfr@aspen.pdh.com (Jon F. Rosen) Subject: While dragging, text in NXImage from TextField is often invisible Message-ID: <CCDw09.40s@pdh.com> Sender: news@pdh.com (USENET News Account) Organization: PDH, Inc. Date: Thu, 26 Aug 1993 20:38:31 GMT This is really driving me nuts. I have attempted to implement a text-dragging mechanism like IB uses to drag titles around. My first pass is to merely try and drag the full image of a TextField to another text field. The text is put on a pasteboard as (NXAsciiPboardType) but the entire text field is turned into an NXImage needed for the dragImage:... operation. My early version of this subclassed TextField for both source and destination fields. The only problem is that both mouseDown: and mouseDragged: mean something inside a TextField and I don't want to disrupt that normal operation. My early version used Alt-mouseDown inside the TextField (if the Alt key wasn't pressed, it did a [super mouseDown:event] to get the normal behavior). All of this worked just fine and I could drag DragSourceTextFields around and deposit their text (but not their formatting by choice) into DragDestinationTextFields. I had to do a bit of gymnastics on the View flipping and offsets to get the NXImage to look right, but using [image setFlipped:YES] and the appropriate offset to dragImage:..., I got it to look right. Now I want to do something slightly different. I created a custom view class called TextFieldDragShadow which will be sensitive to a mouseDown operation inside it. The shadow view is expected to sit "around and under" a regular text field by about two pixels, providing a "drag text" border area. Thus, I can leave the regular drag operations in a TextField (for selection) alone and still just use dragging to move the text. This isn't necessary in IB because the title field on the palette is read-only so you can just do mouseDown without worrying whether the user is going to modify the text (at least until it is dropped somewhere). Okay, the problem is when I changed the code to support the TextFieldDragShadow, the drawSelf: message to create the NXImage from the contents of the text field is sent to the textfld outlet which points to the actual TextField (before, it just did a drawSelf:self). The frame draws just fine, but the text drawing is weirdly intermittent depending upon (it seems, anyway) whether I have set the isFlipped status of the NXImage and whether I have set the font to bold in Interface Builder. Usually, if the font is normal Helvetica, the text doesn't show up, but when I set it so bold manually, the text appears. Sometimes. But even that behavior is inconsistent. Sometimes it puts the text in my drawn NXImage, and sometimes it just puts the border (it ALWAYS puts the border, though, so I know the lockFocus and drawSelf are doing SOMETHING). BTW, the text always ends up being deposited in the destination field just fine from the pasteboard. Also, all of the drag-and-drop stuff works just fine (cursor changing, etc.). Its just that the stupid text doesn't get drawn in the dragged image. Ggggrrrrrr.... Here is the all the code for the TextFieldDragShadow class and TextFieldDragDestination class. Create a nib with a CustomView of TextFieldDragShadow on the screen, and place a regular TextField on top of it (you can leave any size border you want). Add a CustomView of TextFieldDragDestination class (where the text will be dragged to) and connect the TextFieldDragDestination view to the regular text field as "textfld". Save it all and run it. The "textfld" outlet reliably points to the text field whose text I want to drag. That's why the border gets drawn. But the text is missing (or am I nuts?) Anyone want to take a whack at this one? -------------------- TextFieldDragShadow.h ---------------------- #import <appkit/appkit.h> @interface TextFieldDragShadow:View { id textfld; } - mouseDown:(NXEvent *)event; - (NXDragOperation)draggingSourceOperationMaskForLocal:(BOOL)flag; - textfld; @end -------------------- TextFieldDragShadow.m ---------------------- #import "TextFieldDragShadow.h" @implementation TextFieldDragShadow - mouseDown:(NXEvent *)event { id myImage; NXRect theRect; const char * pbtype[] = {NXAsciiPboardType}; Pasteboard *pb; NXPoint p,q; char *str; // copy textfld text to pasteboard pb = [Pasteboard newName:NXDragPboard]; [pb declareTypes:pbtype num:1 owner:self]; str = NXCopyStringBuffer([textfld stringValue]); [pb writeType:NXAsciiPboardType data:str length:strlen(str)+1]; // create an NXImage and draw the text field into it [textfld getBounds:&theRect]; myImage = [[NXImage alloc] initSize:&theRect.size]; [myImage setFlipped:YES]; // sometimes YES, sometimes NO works [myImage useCacheWithDepth:NX_DefaultDepth]; if ([myImage lockFocus]) { [textfld drawSelf:&theRect :1]; [myImage unlockFocus]; // change the y location to adjust for flipped coordinates p.x = 0; p.y = theRect.size.height; // i have set this to 0 or height // with varying results q.x = 0; q.y = 0; // start the drag operation [self dragImage:myImage at:&p offset:&q event:event pasteboard:pb source:self slideBack:YES]; } // we're done, clean house free(str); [pb free]; [myImage free]; return(self); } - (NXDragOperation)draggingSourceOperationMaskForLocal:(BOOL)flag { return(NX_DragOperationCopy); } - textfld { return textfld; } @end ----------------- TextFieldDragDestination.h ---------------------- #import <appkit/appkit.h> @interface TextFieldDragDestination:TextField { } - (NXDragOperation)draggingEntered:(id <NXDraggingInfo>)sender; - (BOOL)performDragOperation:(id <NXDraggingInfo>)sender; - (BOOL)prepareForDragOperation:(id <NXDraggingInfo>)sender; - concludeDragOperation:(id <NXDraggingInfo>)sender; @end ----------------- TextFieldDragDestination.m ---------------------- #import "TextFieldDragDestination.h" #import "TextFieldDragShadow.h" @implementation TextFieldDragDestination - (NXDragOperation)draggingEntered:(id <NXDraggingInfo>)sender { // if you are in your own text field, don't accept drag if (([[sender draggingSource] textfld] == self) && [sender isDraggingSourceLocal]) { return(NX_DragOperationNone); } // else accept a copy return(NX_DragOperationCopy); } - (BOOL)performDragOperation:(id <NXDraggingInfo>)sender { int len = 0; char *str = NULL; const char *pbtype = {NXAsciiPboardType}; // get data from pasteboard and copy it to destination [[sender draggingPasteboard] readType:pbtype data:&str length:&len]; [self setStringValue:str]; return(YES); } - (BOOL)prepareForDragOperation:(id <NXDraggingInfo>)sender { // sure, we'll take anything :-) return(YES); } - concludeDragOperation:(id <NXDraggingInfo>)sender { // nothing left to do return(self); } @end ----------------- TextFieldDragDestination.m ---------------------- !!!!!!!!!!! Extra credit :-) Anyone want to give me ideas on how I would just draw the text into the NXImage with alpha so that only the text would be dragged around, not the whole TextField (this would also be useful for dragging text selections as well). IB doesn't do anything special for a border, but I might also want to have a dropshadow behind the letters to make them stand out more. I guess I could do this with direct Postscript single functions after getting the text out of the text field.

I want the lowest common denominator possible (these figures will appear on a conference's CD-ROM), and I'm leary that an alpha channel will cause problems (one of the technotes indicates that Next's format is non-standard). I know I can use Icon to re-save the tiff as 1-bit/no-alpha, but I'd rather do it in one step and from the command line. I scanned the Nextstep documentation for NXImage and NXBitmapImage, but didn't see the magic incantation to change the depth or alpha saved. Any hints?

The problem with this is that you (or somebody else) might want to have a subclass of your class which doesn't simply return -rank, but does something else. Another advantage of using accessor methods such as -rank above is that you can set a breakpoint on them, making debugging easier. Accessor methods really aren't that slow; you can easily do 300,000 of them in a second (try measuring it). But if you really can't afford the extra 20 cycles, you can always use public variables. -Simson -- ................................................................simson

Date: 27 Aug 1993 08:43:45 GMT Organization: California Institute of Technology, Pasadena Message-ID: <25khg3INNfqk@gap.caltech.edu> Horrible puns aside, I was wondering if anyone on the net had come across a nice find-panel object. Yap has such a beast, but it doesn't support NXFindPboard, regexes, or replace. Barring any suggestions from the net.community for pointers to prior art, I guess I'm planning to write such a beast myself, including a spec for a protocol to search embedded Cells. Question: How many other developers would *really*, *really* like NeXT to ship /NextDeveloper/Examples/Appkit/Edit? I know and you know that there are some ugly things in the code, and the authors may not be all that proud of that source (at least, I hope so, :), I've been reverse-engineering big chunks of it, and they take remarkable liberties with the AppKit), but there are some mighty nifty things happening in there that we would benefit from. Not to mention extending Edit itself! ObExample: StructText. Edit has no less than 4 subclasses of Text, and one of the most interesting by far is the black magic behind the structure tags. Turns out that part of it involves the undocumented mysteries of writing a replacement for NXScanALine and NXDrawALine. In trying to implement my own version of this, I wanted to use replace:sel:length, which has enough bugs of its own that it took almost 3 days of poking around to find an acceptable solution. In the end, the bugs aren't in the system (generally ture), but always in the documentation (because it never tells you enough to really understand what goes on behind the scenes) ObRant: As the NeXTstep (seeing as how fashinable retro affectations are these days :) market moves towards custom-apps, commercial development, and basically away from education, the dissemination of programming wizardry is drying up. Cool code and architectural designs become trade secrets, which I'm not going to complain about too loudly, but the net effect is that the "training" code base of good NS code for budding developers to read and learn is shrinking, relative to NS's increasing complexity. The only full-scale app left is Draw.app, which is showing its age :) Certainly, I would even pay to become a Registered Developer if it came with lots more code. The whole issue is complementary to the "We don't need no stinkin' code thread" -- even better (from a practical standpoint) than AppKit source is source that shows how to properly use and subclass AppKit objects. Fundamentally, the only way to learn how to program a system is reading and studying code. NS will be much stronger if the developer CD came with a few hundred random apps from NeXT and other participants in source -- even the throwaway, testbeds and single-fn feature tests would be useful. But it will never happen, between Copyright, clean-up, and resources. As it is, even the net-archive-server system is beginning to militate against releasing work-in-progress or throwaways; beyond mere infrastructural issues of disk space and bandwidth, we don't have any editing ability to help us sort out the relevant work.

Date: 27 Aug 1993 14:17:07 GMT Organization: U.S. Department of Commerce, NOAA/AOML Message-ID: <25l513$92u@wave.aoml.erl.gov> Although this is a simple topic, it was a little frustrating for me as I am just starting out. I was actually using what was suggested to me to create the outpput file, but I think I found out what is supposed to be done: outStream = NXOpenMemory(NULL,NULL,NX_WRITEONLY); This line will create a stream without a file. Then you can use NXSaveToFile() to create a file with a specified name. This was the problem that I was having. I wanted to use NXSaveToFile() to create a non-existent file, but that required a stream. In order to get a stream to write to, I thought I could use NXMapToFile, but that required a file. Then I found NXOpenMemory(), which creates a stream and then i was able to use the stream in NXSaveToFile() to create the actual file. The only thing I am wondering about is if there are two copies of the info that I NXPrintf() to the outstream. For example, if I open a stream with NXOpenMemory() and then use a series of NXPrintf() statements, they write to a location in memory. Now when I use NXSaveToFile(), what happens? Is there a copy of the stream saved to another memory location, the location being the file named in NXSaveToFile? I think this would be good for the FAQ.... Thanks a lot for the help,

The "in" > keyword means "I don't want to change that reference, I just want > the value contained in it". Yanik, because objects (ids) are passed by proxy, there is a big different in the way they are handled. The in keyword is intended to specify (much like const in regular C) that the data pointed to by the pointer will not be changed. This permits a one-way copy to be made and makes sure the receiving application does not try to pass the data back to the sending app. Since objects are NOT copied back and forth anyway, the use of in is at best redundant. Worse, it might be confusing things when you try to use it to send a message back to the sending app through the object. One more thing... I assume that you have "run" the connection on the client side as well as the server side. This is the only way a client can receive a message on a connection unless it is awaiting a response from its original message sent to the server (synchronous callbacks are allowed without running the client's connection since it is already waiting on the connection anyway). Since oneway messages are by definition asynchronous, you MUST run the client's connection. If you haven't already thought of this, you must do the following in the client side: remoteObject = [NXConnection connectToName:...]; [[remoteObject connectionForProxy] runFromAppKit]; assuming the client is running under an Application (otherwise, just use the "run" method).

My first intention, was to use the (oneway void) keyword but since I must do something after I send a message to all members (each one with its own thread) of my list. By now my strategy works. The strategy is as follow: Client1 create a messaging object en encapsulate the message Client1 sends the messaging object (as Proxy) to the server. Client1 sends -free message to the messaging object. The server re-sends that object (as Proxy) to each registered client (except Client1). Each client (except Client1) retreive the data from the Proxy (messaging object) Each client (except Client1) sends -free message to the Proxy (messaging object). Since the messaging object conforms to the NXReference protocol, the messaging object is -freeed only when all the clients in the network have sent the -free message. In the - init and - free method of the messaging object, I use the "gettimeofday()" function to know how long the object lives, the -init is the born of the object and the last -free sent by a client -- the one that reaches the [super free] -- is its dead. As I expected, the life of the messaging object is directly proportional to the number of clients on the network. With just 2 applications (Client1 and Client2) and just one sender (Client1), the life of the messaging object varies between 20000 usec to 35000 usec. When the Client2 does something with the object (printing its contents once every 10 messages received), the life is longer (50000 to 70000 usec). With 10 clients and 1 sender, the life varies from 300000 to 700000 usec when the receiver just discard the messaging object and from 500000 to 1500000 usec when each client prints the content of the messaging object in there respective terminal window. I have the strong feeling that I could make a better job by using the "oneway" keyword with, of course, the "bycopy" and "in" keywords for the parameters. If I have full satisfaction when I use DOs as Proxy, I don't have the same feeling when I use them as Copy. Each time an application (the server or the client) receives a copy, it crashes. Yes, I have made my messaging object conform to the NXTransport protocol!

I assume you mean that a single click will do something, but a double-click will do something else that doesn't include the single-click behaviour. Well, the UI guidelines say this is bad, but of course you know that. The author's of workspace probably knew it too, but they were sensible enough to ignore it for shelf clicks and double-clicks where the non-standard behaviour is much more useful. I think what you mention above is the way it has to be. If you get a single click event, you MUST wait for a double-click interval before doing the single action to make sure that the double-click doesn't come. Hopefully you're not planning on doing this without a good reason, and it will only be that way in certain parts of your app. Hopefully, the things which need to act this way are Cell or Control subclasses. Just do it in the mousedown of the subclass. If there are several subclasses of ButtonCell (say) that need the behaviour, make a subclass called DualActingButtonCell, and then have the other subclasses inherit the behaviour from this intermediate class. In other words, if you work it out right, you won't need to do it over and over. ____________________________________________________________ Mike Ferris God, to me... mike@lorax.com is a verb, not a noun, Rubicon Software proper or improper.

There is a class called InspectorManager which is OK and shows the extent to which inspector handling can be taken.

True, we won't have access to Edit.app or HeaderViewer, but we will have a good collection of source to build on. And, while being able to get the functionality that is in Edit or whatever is what I'm sure we are all after, I'd much rather that NeXT got an intern or two to separate those classes out and release them on their own, rather than dumping the whole source tree on us.

The archive is named FindPanel-1.0.tar.Z and there is an associated README file. It is designed to be a dynamically-loaded bundle that can be dropped into a project under development with minimal fuss and effort. I created the SearchableText protocol Alex Blakemore mentions with Matrixes, selection lists, and, of course, the Text class in mind. My goal was to create a general protocol which any object that had text it wanted to "vend" for searching/replacing operations could implement. For a Text-like object, this is simple. For a Matrix, a programmer would have to decide how to map a linear sort of text model to two/three dimensions. This is not all that difficult either, and there is lots of documentation to explain things. The FindPanel doesn't itself do the searching/replacing/regexpr stuff-- that's the job of an implementor of the SearchableText protocol. I include a simple example app, a category to the Text object that provides much of the necessary code to implement SearchableText for any Text object, and a regular expression module (a quite nice one) posted to comp.sources.misc (vol27/vol29) by Tatu Ylonen. I'd be interested in implementations of the SearchableText protocol for NeXT's *Kit classes, as well as others, to be included (with copyright notices and documentation, as appropriate) in future releases of this bundle/archive. Suggestions, criticisms, and questions are also welcome. Christopher J. Kane kane@gac.edu kane@cs.purdue.edu

Wow. That's two inoperative statements in one sentence. NeXT's OS is a BSD server running on top of Mach 2.5, and in most real-life terms System V is much more of a standard UNIX architecture than BSD these days. For all that BSD has less historical cruft, it's also gat far less market penetration. Nope. The idea of separate servers sitting "on top of" a distinct mach kernel is at least in mach kernels preceding 3.0 (like all NeXT kernels to date) is just a nice abstraction but not in any way a functional description. If you don't believe me, go grab your BSD sources, the NeXT kernel and a disassembler. You'll find that virtually all the relevant parts were compiled straight from the BSD sources. SCO crowing forever about how many hundreds of thousands of system V derivatives it has sold running on single user unconnected 286 PCs doesn't alter the fact that most UN*X software was written for BSD derived systems. A quick scan of any of the major archives should convince you of that. The underlying O/S is nothing exceptional. Yes. It is just good old solid _standard_ BSD 4.3 with a few Mach extensions. As a matter of fact, this was one of the central reasons why I bought a NeXT once upon a time. Carl Edman

What if you end up using a subclass that has -rank {return rank+1;} Which method would the compiler inline? And if it's the object is type "id", how will the inline check to see if it's even responded to? There is a way to achieve the speed you need. If an object is declared as follows: @interface MyObject:Object { @public int rank; } @end -myMethodInSomeOtherClass { MyObject *theObject; theObject->rank; } I know this feature is present in the NeXT version of Objective-C, and I would expect it to begin making it's way back into Gnu-Objective-C In real life application the overhead for runtime binding is not all that bad. If you actually create a full application, you will find more cycles burned on excessive drawing or poor algorithms. Those type of delays are easily perceived by the user. Those are the things that make a program slow. If you were to optimize all your method calls as inlines, the speed improvement would be imperceptible to a user. The rare exception is when you do the same method over and over. Even then, you probably shouldn't bother to optimize unless you are talking about several thousand calls in close proximity to the same method.

To get rid of the alpha channel, do this: NXApp = [Application new]; image = [[NXImage alloc] initFromFile:argv[1]]; [image setBackgroundColor:NX_COLORWHITE]; [image writeTIFF:stream allRepresentations:YES]; NXSaveToFile(stream,argv[2]); That will still leave it two-bit.

There is one good reason to override malloc(), NeXT's is broken. It doesn't guarantee that the memory is actually there. Do a malloc(1024 * 1024 * 1024 - 1) (you need the minus one to avoid another bug) and see what you get back. Suprised? I didn't think my disk could support that much VM! Now add a loop that touches each page, recompile, save anything you're working on and run it again.

I'm less interested in the function call than I am in how the function's address is obtained. When the type of the receiver is known (or at least its branch in the inheritance hierarchy), do selectors still go through the selector hash, or is the C++ style table jump used? The latter gives runtime binding with very fast selector resolution. >What if you end up using a subclass that has > -rank {return rank+1;} >Which method would the compiler inline?

Have you tried to newfs the disk, and than use mkfile to create a contiguous file? This is much the same as /private/vm/swapfile, and if the file is created in one fell swoop, the access to it should be pretty efficient. Plus, you get to use normal tools like dump or tar (or SafetyNet) to backup the file system on disk to tape. >Also, will the disk blocks be read in the same contiguous order in the >Nextstep 486 and Nextstep '040 raw devices?

I can't see how NXStreams would be significantly faster than the standard C functions in the code [deleted] above. The main difference is *when* you pay for the file access: in small increments with fprintf, or all at the end with NXStreams. It seems like both mechanisms would do the same amount of work. [Yes, I admit NXStreams may be slightly faster, but they probably use more memory, especially for longer files. And more memory in a virtual memory system translates into extra disk time, which slows you way down.] The reason I prefer the standard C functions is because they are standard: they work on C everywhere. More people understand them. And it would make porting the program to a non-NeXT environment easier. Finally, I don't think speed is nearly as important as most programmers would like to think. (See my recent post on Optimization.) > In any case I think you should use open etc so that you have > file descriptors and not FILE pointers. I would like to know why you prefer file descriptors to standard C files. I admit that fd's may be slightly more efficient, but they're not standard C. I think clarity of code and portability of technique are far more important than how fast the code executes (except, of course, when writing optimizing compilers:-). Joseph

NeXT has made an official announcement about what you can expect in 3.2. POSIX support is merely a "future direction"--NeXT *never* committed to deliver it with 3.2 (or even 4.0). It's just a "checklist item" anyway. Programs will have to be compiled and linked as either non-POSIX (default) or POSIX. If you go the POSIX route, expect your code to be portable to other POSIX platforms. (That's good, right?) But forget about using BSD/UNIX features, Objective-C, the AppKit --everything that makes NEXTSTEP attractive. POSIX is a crutch, like SoftPC or co-Xist or Executor. Any of them can manage "hello world," but they're hopelessly alien with respect to each other. The most you can hope for is sharing screen real estate (maybe). What's the difference? POSIX is coming from NeXT and not a third party. But NEXTSTEP is not "evolving toward POSIX," rather, you're getting the moral equivalent of OS/2's "DOS compatibility box"--and paying for it in terms of increased memory and disk space requirements. -=EPS=- -- DOS is merely retarded.

Executor supports cut and paste of Rich Text and of PICTs. Being able to cut and paste PICTs has always been useful when two applications are running under Executor (Word and Excel come to mind), but with David Burrowes' new (FREE) utilities that translate between PICT and EPS, any program that supports filter services should be able to use the graphical output of a program running under Executor (textual output is already handled by the RTF pasteboard). I don't know what pasteboards SoftPC and co-Xist support, if neither the RTF nor the EPS pasteboards are supported, then I guess Executor is alien to those two, but not because Executor's not doing the right thing. True, Executor will *probably* never be as integrated into NEXTSTEP as much as a *well written* NEXTSTEP app, but it can already do significantly more than share real estate, and it there's good reason to believe that there will be still more integration in the future. I put the "probably" in the above paragraph because with sufficient work there's tons of stuff that we *could* add to Executor/NEXTSTEP. Right now we're putting a lot of work into Executor/DOS, but we haven't forgotten our NEXTSTEP customers (and we even do our DOS development under NEXTSTEP). With all the changes of late, a lot of third party developers are having severe financial difficulties right now. We're very lucky in that we will soon have a cash cow that we can milk during the dry season. BTW, our sale ends Tuesday; we will *not* be extending it into September.

Actually, it my very well be worse considering the $#^%#$# limit of 64 kByte on the size of one "read" through the generic SCSI device.

Consider classes loaded dynamically from the program: selectors for new methods may differ depending on the order in which classes are loaded. NeXT's compiler takes some short-cuts with the appkit selectors, which seem to be invariant.

The latter gives > runtime binding with very fast selector resolution. I believe the compiler generates an indirect call from an address in a local data structure. The data structure, however, is loaded at run-time based on the method name in the message. So it only differs from a direct call by the address indirection (ignoring additional task startup).

Well, maybe not evil but the source of many holes in the feet of C++ programmers. As soon as you spread inline accessors around, you have destroyed the ability of the class designer to modify its instance variables without worrying about what clients are dependent (due to inlines) on certain variables being in certain places. (As well as the problem cited above.) Don't get upset about the overhead of accessor methods until you are SURE that it is a significant factor in performance. For example, using an accessor to retrieve the linewidth of an arc isn't going to make any difference if you are then going to image the arc through the Window server. If you are in a tight enough loop that the accessor overhead actually does make a difference, you probably have better alternatives than inline, e.g., copy the value to a local variable or add a method to the target to perform the loop internally. #end --------------- Peter Kron Please don't dominate the rap, Jack, Corona Design, Inc.

What I'd really like to be able to do is have browser-like functionality (tree-oriented), but where the individual columns could be different widths. I've messed around with grabbing the Matrix inside a particular column and sending it some of the different size*: methods, then asking the browser to re-display, but the browser did not resize properly; err, it really didn't resize at all. Since I did this all through IB and gdb, I'm not sure if I was doing everything completely properly -- you know, stuff like having the resize "springies" set up. Has anybody out there had to tackle this problem? I guess I could use a simple matrix in a ScrolledView, and have the matrix cell prototype set to NXBrowserCell so that I would get the icons, etc. Seems like at that point I'd be re-designing NXBrowser, though.

I want the C compiler to compile ANSI C and Objective-C code, not RTF-enhanced code.. Given the amount of really useful stuff that NeXT could do, adding support in the compiler or preprocessor for stripping RTF out of source files just really isn't high on the list (or on the list at all). Given that Objective-C is in the GNU release of GNU C these days, I've been writing code with an eye to portability to other platforms. Introducing RTF in the C source code is just another gratutitous incompatibility. If the compiler group in NeXT is looking for stuff to do, there's certainly improvements that can be made in other areas that actually help: improved code generation, improved compiled header support for multiple architectures, improved Objective-C runtime performance, etc. Heck, I'd rather see NeXT work on something that I can really use, like a port of Emacs 19 that uses NeXTStep for its windows rather than being bound to X. This would be a bigger productivity improvement for most developers RTF support in the compiler. There is a difference between well documented, well written code and code that just looks nice. RTF will help you get nice looking code, but isn't going to help in a big way to give you *good* documented code. IMHO, Louis Mamakos -- Louis A. Mamakos TransSys, Inc.

The day I switched over to writing code in rtf, the number of comments in my code when up by %1000. When using straight ascii, I would want to avoid putting comments in because they would cause visual clutter. With rtf, I enjoy putting in comments because they are very unobtrusive. I also feel that overall quality is improved by rtf because there's a feeling that the code *can* be viewed by others (hard to say for straigh ascii), so there's an impetus to make even more well-written code, since you begin to feel that what you're doing will have more lasting value. I still use straight ascii for some of my stuff. Basically anything that is throw-away code for test purposes I do in ascii because it saves me a couple of seconds on the formatting end. Also, if I know its throw away, doing it in ascii helps remind me to throw it away 'cause it looks like garbage. I thereby resist the temptation to integrate RAD-type test code into the rest of my long-lasting rtf code, thus keeping the two separate. There are probably a few software projects which have their fair share of "prototype" code still in them. For me, once my code makes it to the ranks of rtf, its good stuff. :-) Having been the focal point for most users of rtf source in the world, I can say that those who use it (and who have suffered through the problems cause by new NS releases) *really* like it, and most would not go back to straight ascii coding.

Beckman <zac@dolphin.com> Subject: Dolphin Kit 3.2 Beta Participants Wanted Message-ID: <1993Aug30.082356.9084@dolphin.com> Sender: zac@dolphin.com Organization: Dolphin Technologies Inc. Distribution: usa Date: Mon, 30 Aug 1993 08:23:56 GMT Dolphin Technologies Inc. is seeking participants for the beta release of Dolphin Kit version 3.2, which is entering beta this week. The final release of this version of the kit is scheduled to approximately coincide with release of NeXTSTEP 3.2 (this beta release will operate on NeXTSTEP 3.0). If you are interested, please send electronic mail to <beta@dolphin.com> requesting participation. You MUST have NeXTMAIL capability and be able to receive messages of up to 1 megabyte in size. In response to your request a non-disclosure form will be sent to you via NeXTMAIL; this form must be signed and returned before participation in the program begins. Following is detailed information on Dolphin Kit version 3.1, not yet updated for the enhancements in version 3.2: July 1, 1993--Dolphin Technologies Inc. announced the availability of the Dolphin Kit NeXTSTEP compatible class library, version 3.1, for NeXTSTEP (available for both Intel and Motorola hardware). The kit is a set of classes which run in the NeXTSTEP environment and focus on common functionality that many applications require. The classes expand upon the existing NeXTSTEP API and deliver new objects not formerly available. The Dolphin Kit provides a comprehensive set of tools, classes, and protocols for building applications that use a high-level object oriented approach to many common needs in application development. The kit provides services that include: Simple string and "sentence" storage and manipulation. Encapsulated use of Mach files and devices (i.e.: flat files). Management of C Threads and multitasking. Extensions to several standard NeXTSTEP API classes. New container classes. An interface to generating NeXTMAIL. Limited support for error and alert panel objects. Encapsulation of NXStreams. Part of the functionality of the Dolphin Kit is a set of tools for building more robust applications. Most applications make use of memory to store strings or other blocks of data. Dolphin's DSString class can be used to greatly simplify direct use of memory. For example, calls to memory allocation and free functions are encapsulated. By encapsulating the use of memory in a robust library, many problems in the area of memory management and memory overrun are prevented. The Dolphin Kit helps by providing: Several DSString classes for containment of a block of memory (typically used to store terminated character strings). The DSErrorString class can be used to represent and help in handling error conditions. A DSParser to provide greater flexibility in manipulation of character strings. This makes it possible to manipulate such strings without danger of memory overruns and other miscalculations. Classes for the encapsulation of Mach file and device manipulation and use of multitasking via C Threads. Tight integration between the DSStream, DSFile, DSProcess and DSString class make an excellent tool for execution and reporting on Mach command line operations. A DSNodeTree for storage and manipulation of data which can be stored in a tree. Subclasses of List for sorted storage and delegate notification in the event of changes to the container contents. A simple but very handy encapsulation of memory allocation using NXZone's. The DSMemory class makes using zones and blocks of memory a little bit less tedious, and adds useful methods such as length. Generation of standard electronic mail and NeXTMAIL is supported with the DSMailer class. This class can be used to generate NeXTMAIL with attachments and rich text contents. -- Zacharias J.

Well, I think NeXT wants you to believe this means "stuff started from /usr/lib/NextPrinter/lpd.children" i.e. if you have some sort of daemon process that would be normally be started at boot time from /etc/rc.local and sticks around forever, starting it from lpd.children instead lets it have access to the Window Server. (But that's not good enough for you, is it?) So what's special about the printer daemon? Nothing, really. There's just a little conspiracy between the Window Server and /usr/lib/lpd. Here's the abridged version: lpd allocates a Mach port, and checks it in with the Bootstrap Server under the name PrintService, and forks a C thread to monitor that port. When the Window Server starts up, it looks up "PrintService" and sends a minimum-size Mach message with its access port as the reply port. lpd then checks that port into a Bootstrap subset as WindowServer. Since lpd's children inherit lpd's bootstrap port, they will have Window Server access. If the Window Server dies, the next time it's restarted it will message lpd with the new access port. If lpd is killed, any tasks holding send rights to its "PrintService" port will receive port death notification from the kernel. So the Window Server presumably knows to poll periodically to see if lpd has come back. Now, suppose you're a root-privileged process that wants access to the Window Server, but has bad heredity. :-) The sleazy way to get around this in 3.1 goes something like: look in /usr/spool/lpd.lock for lpd's process id. Use task_by_unix_pid() to obtain its task kernel port, then task_get_special_port() to find its TASK_BOOTSTRAP_PORT. Use that to do a bootstrap_look_up() of WindowServer. If that succeeds, check in the "stolen" port as WindowServer under a subset of your original bootstrap port and set your current bootstrap port to that subset. (Don't forget to deallocate any ports you no longer need.) [Note that there have been significant changes since NS 2.x!] -=EPS=-

Message-ID: <1993Aug30.171155.2887@IRO.UMontreal.CA> Keywords: Installation, mach, 3.1, floppies Sender: Hugo DesRosiers, MediaSoft Telecomm Organization: Universite de Montreal Date: Mon, 30 Aug 1993 17:11:55 GMT We have a very nice notebook here on which we would really like to see NS/FIP. Of course, this is PC hardware, and trying to get a SCSI controller in a docking station on the notebook didn't work. So I created some floppies to boot and install NS/FIP the hard way. After getting the kernel with the installation disk, startup stops at the "Root disk" question. fd0 is choosen, and the system continues to boot (starting mach_init and init), from a home-made floppy. It then asks in which language installation must be done, and then gives a very nice "/NextCD/CDIS/localecho: cannot execute.". Then a shell prompt appears, and that is it. It turns out that most of the programs on the floppy will give the same error message. But some do execute. For example, in the /usr/etc are the "disk" and "fdisk" programs. Doing a /usr/etc/disk do work, and disk seems to work correctly (disk -q /dev/rhd0a returns "IDE <something>"). But fdisk gets that "cannot execute" message. If I can solve that problem, I'll install NS/FIP on the notebook and then post a find / -print of each floppy I used to install a minimum NS/FIP on a PC machine... Please awnser by email, I don't have time to read the news too much. Thanks, Hugo DesRosiers.

The disk driver can read or write much larger peices of data than the sg driver. (There is a 32k transfer limit in the sg driver.) I once had to do a driver for a SCSI disk which had a proprietary format and accessed it via the sd driver. Use partition 'h' as described per the man page. (Access this way can be quite fast. In testing I had achieved transfer rates in excess of 3MB/sec.

SCSI disks are transportable between architectures. Thus I would say there is no problem. There would be a problem if you tried to use an IDE drive on a PC however.

YES! you've hit one of my favorite peeves about NeXT, having to use the damn mouse for the simplest things (much as I love NEXTSTEP) TeXView.app does it right IMHO. any app displaying multipage readonly text (FaxReader, PreView, NG, etc) should emulate each and every feature. PreView does only a subset :-( source is in /usr/lib/tex/src/texview here is a partial list: the page number is selected when you enter a page so you can just type a number to go to that page. the space bar pages forward, going to the bottom of the current page if not there yet. left arrow = prev page right arrow = next tpage up arrow = scroll towards top of current page down arrow = scroll towards bottom of current page since the view in this case does not allow selection of text, it even uses mouse drags to scroll the page, which is useful for simultaneous horizontal/vertical scroll. I think it even does f for forward, b for backward without making you hold down the command OR shift key either. Developers, please adopt TeXView techniques to allow us to keep our hands on the keyboard. Stuart has similar good techniques for scrolling, switching windows with arrow key combinations. P.S. another good idea to adopt is Edit.apps trick of highlighting the miniwindow for a doc if it contains unsaved changes.

Particularly Robert who came up with the transparent text imaging code which we are now using. It works, its cool (as all good NeXT stuff should be) and even better, it does interapplication drag-and-drop FOR FREE! I had heard all about this stuff but its the first time I have ever done any real "graphic" work on the NeXT (most of my work has been database internals) so I was truly amazed when I took my working app (with the transparent drag-and-drop functioning quite nicely thank you) and brought up a second copy of the app "just to see what would happen". I dragged an image from one copy of the app to the other's destination text field AND IT JUST WORKED! Thanks again to everyone. Jon

Plus, you get to use normal tools like dump or tar >(or SafetyNet) to backup the file system on disk to tape. You might also want to change the disk characteristics when using newfs and/or tunefs (only a few inodes, set minfree to zero, ...). For details, have a look at the mkfs, newfs and tunefs man pages. Access through the file system is only somewhat slower than direct access to the raw device (or (uglyly) to the SCSI disk (through sg or sd)). But it has the advantages that the file may be backuped, or moved to another disk or accessed through a network file system (NFS, AFS, ...). Let the path name to the file be configurable, so if someone really wants to use the raw device (s)he can change it. Access to the raw device needs additional privileges for the app and you must take extra care not to take the wrong device (i.e. your home partition). -Marcel

This is an easy one. In the GNU and NeXT Obj-C compilers, the "pointer to a class" syntax gets you STATIC TYPING, not STATIC BINDING. It permits the compiler to give compile warnings when you send an "invalid" message to an object of a static type. However, the compiler still generates the same old objc_MsgSend() function call whether the object is a dynamically typed "id" or a statically typed "pointer to a class". Static typing is also useful to "pierce" the encapsulation of an object. Any statically typed object will "give up" its ivars using object->ivar syntax. This is NOT a good thing to do unless you are absolutely sure that you know what you are doing and you are not concerned about possible future expandability problems. Jon Rosen

Before making this judgement, why don't you actually TIME how long the dynamic message dispatch takes as compared to a normal subrouting call? It doesn't take that much longer, and unless your method is trivial and called very frequently, you probably won't notice a difference. It is, for example, orders of magnitude faster than making a system call. There are ways of getting a pointer to the implementation of a method, and invoking it as a function call through a pointer. It's just that in most cases, it's just not worth the trouble. Louis Mamakos

Since I don't define a drawSelf:: method, I don't think I can use the printPSCodeInside: method to get the printout. If I try this, I will get a blank sheet for the output. I figured out how to implement a copy: method by creating an NXBitmapImageRep from the image on the screen and pasting this to the pasteboard. However, I don't know how to do something similar for sending code to the printer. Can anyone offer suggestions? I think all of the relevant info is the following: I don't implement a drawSelf method, but just draw dots directly on the screen (for reasons of speed and synchronization with sound output) with the commands [self lockFocus]; PSrectfill(x,y,1,1); [self unlockFocus]; The window backing is `NX_BUFFERED' The image is Black and White with no transparency.

The phrase "unless your method is trivial and called very frequently" implies that method calls are rare in typical code.

Date: 01 Sep 1993 13:07:13 GMT Organization: University of Passau, Germany Message-ID: <CPESCH.93Sep1150713@markov.fmi.uni-passau.de> Hello! I hope someone can help me with the following Objective-C problem: Is there a way to check if an object is deallocated (without causing errors)? I.e. if I have a pointer to an object (id) and this object receives a free-message (from somewhere else) then I have a pointer that isn't nil but doesn't point to an object. In this situation it is usually a bad idea to send messages to the "nonexisting object". ;-) So I would like to check if the id points to a well allocated object before sending messages to it. If this isn't possible, maybe someone has an idea how to solve the following problem in another way: I have three views: A, B and C. C is a subview of B. A is a special subclass of View and receives at run-time a pointer to B. (It has a new id to store this pointer). But B can be any kind of view and "doesn't know anything about A". Now A "lends" C from B (i.e. makes C a subview of A. Then of course C isn't any longer a subview of B). When A is deallocated then it should "give C back to B" (i.e. make C a subview of B again). This isn't possible if B was deallocated in the meantime. It can happen (for example) when the whole application is deallocated and B gets its free-message earlier than A. In this case A should not try to give C back to B. (This is why I want to check if an object is deallocated). Because B can be any kind of view and is determined at runtime I only can change the methods for A but not those for B. (If both had pointers to the other view and I could overwrite the free-methods of both, it would be easy ...). I hope you understood my problem and can help me. Many thanks in advance, Christoph Pesch (cpesch@markov.fmi.uni-passau.de --- NO NeXT-mail please)

A significant portion of Brad Cox's book, "Object-Oriented Programming, An Evolutionary Approach" is dedicated to explaining just how to implement a compiler that supports static binding (as well as dynamic, of course) regardless of the inheritence chain-- as long as single inheritence is being used. However, I can find no mention of "categories" in his book. The fact that a category can be dynamically loaded (and then inherited by subclasses) definitely throws a kink into his static binding scheme. > While you're at it, think about the implications of class posing. > > - methodFor: (Object) is your friend. > > -=EPS=- Yes, I'm beginning to believe that any scheme for supporting static binding would force us to give up some nice pieces of what we have.

Most implementations of object oriented languages (especially C++) pay a large premium in the amount of memory they use to enable "fast" messaging. Most C++'s flatten the class tree, creating a large table containing info about all the virtual methods of all ancestors of a class at every node. Not only would this be a huge amount of data in the case of apps using the appkit, but it makes things like dynamic loading and categories much more difficult to implement. In every performance experiment we've done we've found that we pay from 5-10% of CPU time in the messenger. We've also found that we are far more memory bound than CPU bound. That's why most of our work has been to make Objective C more memory efficient. We've done things to enable sharing of class data with the shlibs by not writing on them, tuning the caches so that the hit ratio is about 95%, and laying out the class data in the way it is used. One other reason we use a dispatcher is to enable replacement of shlibs after compilation. Most C++'s embed information about super classes in the implementation of subclasses in the way of offsets. This means the compiler knows the layout of a superclasses methods and puts those offsets in the code it generates. This prevents the shlib vender (us for now) from adding or removing methods from a class that is in a shlib. This capability allows us to fix bugs in a shlib, and add capabilities, while remaining backwards compatable with apps that were built on a previous release of the system. For example, faxing was added in 2.0. Apps built for 1.0 were able to take advantage of this feature without being recompiled. Dave Moore NeXT Inc. Software Development Tools

That little operation could take quite a while "longer" than a function call. :-) I think Steve Abell has a point, even if NeXT's design decisions are the right ones for ObjC. I personally would like to see ObjC folded into C++ with "dynamic" added as a keyword. If you want categories, as Eric noted, you then take the hit of dynamic method table look-up. You take the same hit if you're vending classes which need to be "purely" OO (i.e., eminently maintainable). But for the common case that the class is for internal consumption only, and speed matters, direct function calls would be nice. Cheers, = Joe =

That means you can allow at most one thread can access the List at a time. (See a good operating system text for a discussion of what could go wrong.) The conventional solution is to "protect" with List with a semaphore.

This is something I happened to be thinking about the other day. Let's face it. Anyone can get a free OS of whatever stripe they want. They just steal (copy from a friend) it. If they care about intellectual property rights and happen to be frugal then they choose Linux because they get it for free without stealing. Other than those banging on the source, most Linux users probably know someone who will let them copy their USG, Esix, SCO whatever so one might argue that Linux users are the safer bet. And since they didn't spend anything on the OS they have more money available for applications. Anyway, if I was selling a major package like that I would consider a Linux port and include the OS in the package. :-) -- D'Arcy J.M.

This should be fairly transparent after you make the changes. 1. Copy PB.app to ~/Apps (you'll modify this and need your own copy) 2.

You can include a kernel patch (or patched kernel) in your package, and even send the patch to Linus to include in the standard kernel. You don't need to work around kernel bugs, you can fix them (and don't tell me that the USL-derived Unixes don't have bugs).

How much state does your calculation require? My personal recommendation would be to have a timer constantly kicking off your calculation, so that regular screen events can get through. This is the easiest way of 'threading' your application. If you look up DPSTimedEntry, you'll find information regarding the recurring execution of a function. Also, you could look up perform:with:afterDelay:cancelPrevious:, which is an object category (I think) that allows you to 'launch' a method in an object after a specified number of milliseconds. Both methods should allow your program to seemingly handle input and calculation simultaneously. As a little background, the primary thread (usually there's only one) of your application handles events through the event loop in the Application object. This object also allows the timed entries and performs to take place. If you kept a piece of code constantly running, there would be no way for the program to ever receive events (including quitting!). Good luck! Ken Anderson anderson@biztech.com Stamford, CT

The result: objc_msgSend() is about 2.28 times slower than a function call. The table jump technique runs about 1.3. He then suggests: >if you multiply a few numbers together, >that's going to outweigh the method dispatch. /steve> time tmmult // Same as tm, but does non-trivial multiply also 25.5u 0.2s 0:31 80% 0+0k 0+0io 0pf+0w Once again, given the density of method calls in ObjC code, we're losing a non-ignorable amount of time in objc_msgSend().

They are a licensee of the Windows source code, and produce a DOS emulator used on a variety of UNIX boxes. Their technology has also been used by Microsoft to help support 16-bit DOS and Windows on NT. There is a lot of discussion of SoftPC in the NeXT groups lately, as this is the technology of choice for Windows integration into NeXTStep. Another approach is Wind/U, a toolkit from Bristol Technology that purports to allow recompilation of Windows sources for UNIX platforms. As such, this is a compile-time option rather than a runtime binary device, but it offers a promise of native-mode apps on the UNIX side. I'll close this post with some material on Wind/U clipped from a recent SunFLASH on world.std.com: ----begin quoted material---- Subject: Wind/U 1.3 - Microsoft Windows and Visual C++ Applications On UNIX Contact: Jean Blackwell Org: Bristol Technology Phone: (203) 438-6969 Email: jean@bristol.com BRISTOL TECHNOLOGY ANNOUNCES WIND/U 1.3 - MICROSOFT WINDOWS AND VISUAL C++ APPLICATIONS ON UNIX - New Version of Wind/U Toolkit Allows Developers to Port By Simply Recompiling Microsoft Windows or Visual C++ Applications to Run As Native UNIX/Motif Programs - - Key New Features Include Microsoft Foundation Class Library 2.0 Support, Integration of Bristol's Newest Xprinter Library, and other Enhancements - Ridgefield, Conn - August 16, 1993 - Bristol Technology Inc. (Bristol) today announced Wind/U(TM) 1.3, a new release of the company's Windows to UNIX(R) portability toolkit with support for Microsoft* Visual C++ applications through the Microsoft Foundation Class (MFC) Library version 2.0. Wind/U 1.3 enables Microsoft Windows and Visual C++ applications to run as native UNIX/Motif(R) applications. Wind/U 1.3 is available on Sun SPARC(R), HP700, and RS/6000 workstations, as well as SVR4 on Intel platforms. The price for Wind/U 1.3 remains $9,950. Like the Microsoft Windows API, Microsoft Visual C++ is quickly becoming the standard object oriented application framework, and the fastest method for creating Windows applications. Visual C++ generates the underlying MFC code that runs on Windows and Windows NT. Wind/U 1.3 now makes it possible for that same MFC code to run on UNIX/Motif, which makes development for UNIX just as fast and easy as development for Windows and Windows NT. A Vision For The Future "We see the industry stampeding towards Visual C++ and the Foundation Class Library," said Keith Blackwell, president of Bristol Technology Inc. "Bristol is creating a path for the billions invested in Windows software development and training to be leveraged onto UNIX. Visual C++ and MFC are the future for programming on Windows and UNIX."

I have an application with a preference panel which is used to let the user choose a font. The panel contains a view which displays two text fields (one for the font family name, and another one for its point size) and a button which is used to display the font panel. I used the following action for the button in order to be able to reflect font setting (my view answers to changeFont:) - setFont:sender { [window makeFirstResponder:self]; [fontManager orderFrontFontPanel:self]; return self; } This worked fine for a moment, until I added another editable text field to let the user set something. Now, it works until the user types in the text field, and then it does not work anymore. I suspect that the responder chain changed, but I don't know how, nor do I know how to program the intended behaviour for my panel. Does the text field trap the changeFont: message? Or does it pass it to a next responder which is not my view? 2. (Second problem) I have another panel with only switches and color wells, and a Set button which a return sign.

Normally, the isa pointer will be set to nil (I think) when an object is freed, buti f the object is freed, then the memory space can be used by another ojbect, so it's really not reliable to look at a pointer and try to figure out if it is good or not. -- ................................................................simson

Many of the finest NEXTSTEP programmers in the world read this group daily and offer invaluable assistance free of charge. To conserve bandwidth, scan the FAQ first when you have a problem. Otherwise ask all the questions you like and don't be shy about offering advice on how things can be improved. In the spirit of USENET, please return the favor to others once you gain facility with the platform. Contributions are encouraged, and attributions will remain attached to all information added to the FAQ. 1.2 Format of this document --------------------------- comp.sys.next.programmer is a very busy place, and many of the articles provide practical tips and source code to solve specific problems. To keep the FAQ at a manageable size without losing useful content, it has been broken into two sections: The main FAQ (this article) -- Contains embedded information about resources and commonly asked questions, with pointers to other sources for extended discussions of specific issues. CSNPanswers -- The collected lore of the NEXTSTEP programming gods is maintained in an email-accessible database at Anderson Financial Systems and an ftp-able package at several Internet archive sites. The index and instructions for accessing CSNPanswers are included at the bottom of this article. ========================================================================= 2 RESOURCES 2.1 Books --------- There are several well-regarded books on the topics of NEXTSTEP programming, Display PostScript programming, Objective-C programming in general, and object oriented design and analysis. The following abbreviated list contains the book generally acknowledged as the best in each category. Send email to CSNPanswers@afs.com with the subject "resources/books" for a full list of publishers and capsule reviews. Introduction to NEXTSTEP Programming Title: NeXTSTEP Programming Step ONE: Object-Oriented Applications Authors: Simson L. Garfinkel, Michael K. Mahoney Publisher: TELOS/Springer-Verlag, 1993 (800)SPR-INGE ISBN#: 0-387-97884-4 Abstract: A superior tutorial for beginning NEXTSTEP programmers.

Publisher: Addison-Wesley, 1992 ISBN#: 0-201-58135-3 Abstract: The infamous, unbeatable "Purple Book." No NEXTSTEP library is complete without it. Objective-C Title: Object Oriented Programming: An Evolutionary Approach Author: Brad J. Cox (, Andrew J. Novobilski second edition) Publisher: Addison-Wesley, 1991 ISBN#: 0-201-54834-8 Abstract: Brad Cox is the "father" of Objective-C, and this was the seminal work on the subject. In addition, the first five chapters provide an excellent introduction to object concepts, irrespective of language implementation. Object Oriented Analysis & Design Title: Object-Oriented Design With Applications Author: Grady Booch Publisher: Benjamin/Cummings, 1991 ISBN#: 0-805-30091-0 Abstract: A classic. Covers design notation and methodology. 2.2 NeXTAnswers --------------- NeXT Inc. maintains this public list of known bug workarounds and helpful examples for frequently asked questions. Articles are available through anonymous ftp from ftp.next.com (129.18.1.3). Read the help file pub/NeXTanswers/README for the latest contents. There is no package with the entire database, but you can use MGET to pull the whole directory. This location also provides MiniExamples and patches. For email access, send mail to nextanswers@next.com with "index" as the subject. An automated system will mail back a list of all current topics and instructions on how to retrieve them individually. 2.3 Internet Archives --------------------- Public domain materials and demo packages are available through anonymous ftp at several archive sites, including sonata.cc.purdue.edu and cs.orst.edu. There you will find John Glover's UHOOP tutorial and another package called IBTutorial, as well as numerous public domain classes and palettes. See the general FAQ in comp.sys.next.announce for a complete list, including international sites. 2.4 ObjectWare Catalog ---------------------- One of the greatest advantages of object oriented programming is the ability to leverage other programmers' work. NeXT publishes an annual catalog with shipping third party objects. Before undertaking new work, especially in base classes, scan the ObjectWare catalog to see if it already exists. Plus, we really need the money. 8^) 2.5 Other Newsgroups and Mailing Lists -------------------------------------- Many other USENET newsgroups provide forums for topics of interest to NEXTSTEP programmers, and NeXT forums exist on other online services such as CompuServe. There are also several unmoderated mailing lists. Other USENET Newsgroups comp.sys.next.advocacy Flamewars, arguments about whether NeXT will survive until your product ships comp.sys.next.software Help with shrink-wrapped applications comp.sys.next.hardware Black hardware problems and white hardware configuration comp.sys.next.sysadmin System and network administration comp.object Object oriented analysis and design; OO tools and platforms; extensive FAQ comp.databases.object Object oriented databases comp.lang.objective-c Objective-C for all platforms comp.lang.c NOT object oriented comp.lang.c++ For the truly desperate 8^) comp.lang.postscript PostScript and Display PostScript comp.os.mach The Mach kernel underlying NEXTSTEP comp.soft-sys.nextstep Less traffic than comp.sys.next.* gnu.gcc.* and gnu.gdb.* Help with the compiler and debugger gnu.emacs.* When you don't want anything better 8^) Other On-Line Services CompuServe - GO NEXT Mailing Lists To subscribe to any of the following groups, send email to <list>-request@<listserver> with the Subject "subscribe".

It also helps if the existing application was implemented in an operating system with an event-driven graphical user interface, because that is the interaction paradigm NeXT users expect. For such programs, you will probably find that the AppKit's maintenance of the event loop removes a significant burden from your existing code. If your core code is written in C or C++, you should have very few problems recompiling. Depending on the source operating system and the age of the code, you might need to use the -bsd, -traditional, and/or -ansi command line flags to compile without complaint. The rest of the effort depends on how well your user interface is segregated from your core implementation. It's usually quick and easy to rebuild the visual portion in InterfaceBuilder (the NEXTSTEP user interface tool). For database access, DBKit provides adapters for all major SQL-driven client/server database engines. DBKit has its own style, but if your program already knows how to generate SQL text, there's a simple method (evaluateString:) to pass it right through. If the source environment is X-Windows, you should be able to recompile without modification under one of several X implementations that has been ported to NEXTSTEP. For commercial applications, consider this a stopgap measure to get up and running, not a final solution. Prior experience in the NEXTSTEP community has shown that users shy away from non-native applications unless a native port is under construction. If the source OS was not event oriented (such as MSDOS), your task will be harder. Since NEXTSTEP users expect to have control of when and why things happen, your code will probably need to be reorganized to remove assumptions about what will always happen in a particular order. In this case, rethink the problem and start from scratch. 3.2 What languages are available? --------------------------------- The favored language for NEXTSTEP programming is Objective-C, a minimal extension of ANSI standard C with a dynamic messaging syntax and runtime system. The native compiler delivered with the Developer package is derived from the Free Software Foundation 'gcc' compiler. It will digest ANSI C, Objective-C, and C++ source code. Objects to be manipulated by InterfaceBuilder MUST have their inter-object messaging methods implemented in Objective-C. Internal implementation can be in other languages, if desired. Other available languages include: Ada, APL/J, BASIC, C++, CraftMan, Eiffel & Sather, Forth, FORTRAN, FP, gawk, ICON, Intercal, Lisps (ACL, AKCL, Elk, Scheme, Xlisp), Logo, ML(CAML, SML), Pascal, PCN, Perl, Prolog, and TCL. For Unix shell programmers: ksh, bash, zsh, rc are available. Send email to CSNPanswers@afs.com with the subject "resources/languages" for a list of publishers and capsule reviews. 3.3 Where is <foo.h> ? ---------------------- NEXTSTEP's genealogy can be traced down the BSD branch of the Unix tree, so /usr/include is a mixture of BSD and ANSI headers. Programs written for SystemV and its variants may contain references to header files that do not exist in the Berkeley Standard Distribution. Known problems include <unistd.h>, <termio.h>, and <termios.h>. <dirent.h> and <dir.h> may also cause confusion because most configures just check to see if these files exist. Both exist under NeXTSTEP, but NEXTSTEP uses the BSD version, dir.h. In general, the best strategy is to remove the offending header reference and recompile. Often header files are included through force of habit, not absolute need for the symbols they define. If the missing header file leads to undefined symbols in the compiler, research the reference. It may be that the undefined reference goes along with a library function that is not provided in NEXTSTEP (see next section). Otherwise, look up the problematic symbol on the source OS, and define it in your own header file of the same name. 3.4 Where is bar(int mumble)? ----------------------------- Just as some header files are missing, so are some standard functions from other Unix variants. Known culprits are putenv(), mmap(), strdup(), and System V shared memory calls. mmap() is available in the Mach kernel, but it's not documented in any header file. Source code for all missing functions (including an alternate implementation of mmap) is available; see the CSNPanswers index for further information. 3.5 How difficult is it to port a NEXTSTEP application to other operating systems? --------------------------------------------------------------- As with importing, exporting effort depends on whether the program was designed with portability in mind. (You *do* have your NeXT user interface segregated from your core implementation, don't you?) You will probably want to stick with 32-bit event-driven GUIs. Objective-C compilers are available for Solaris and other flavors of Unix (gcc) and Windows (Berkeley Productivity Group's Objective-C Extensions for the Borland C++ compiler). A somewhat crippled compiler is also available for the PenPoint mobile operating system (Novotech). It is recommended that you use native tools for building user interface objects and database access, then layer those pieces against your core Objective-C code. On Windows, for example, you might use Visual C++ to build the UI and Access to connect to the database. This solution is not optimal, but it is the best strategy currently available. ========================================================================= 4 TOP 10 FREQUENTLY ASKED QUESTIONS CSNPanswers is the definitive source of NEXTSTEP programming wisdom, but some questions occur so frequently that they are included here to save you the trouble of looking them up. This section will be defined in the October release of the FAQ, based on the frequency of questions encountered while building the CSNPanswers database. In the meantime, sit tight. ========================================================================= 5 CSNPanswers INDEX Anderson Financial Systems maintains this collection of the "best of c.s.n.programmer" as an extension of the FAQ.

Newsgroups: comp.sys.next.programmer From: alex@data.acs.calpoly.edu (Alex Raftis) Subject: GDB and Run Time Linking Message-ID: <1993Sep02.180000.11184@rat.csc.calpoly.edu> Date: Thu, 02 Sep 93 18:00:00 GMT Organization: Cal Poly, SLO Lately, I've been trying to get a 3.1 version of GraphicsWorkshop available for distribution, however, I've hit a snag. It seems that the compiler under 3.1 brought forth a couple of bugs that hadn't shown before, but are now causing random problems. The snag, is that they're in parts of GraphicsWorkshop that are dynamically linked, and I can't seem to get GDB to allow me to trace through that source code. Anyone got any ideas? If I can get this last bug out, I should have a new release ready within about two weeks. Alex

Am I mistaken? Yes, you can, but that's not the point of this discussion. You expend cycles (possibly needlessly) *every* time you [thing gronk]. It would be nice if the compiler could use a different dispatch strategy when certain constraints are known to hold, without the programmer having to do more that state the constraints in a declaration. If you're drawing a lot, it might not make much difference, but if you're trying to use ObjC to *compute*, it would become much more palatable. A recent posting from a NeXT employee makes their position more clear. Thanks, guys. Steve abell@netcom.com
From: reuven@athena.mit.edu (Reuven M. Lerner) Newsgroups: comp.sys.next.programmer Subject: Jumping to Emacs (rather than Edit) from Project Builder Date: 2 Sep 1993 19:25:19 GMT Organization: Massachusetts Institute of Technology Message-ID: <REUVEN.93Sep2152518@primavera.mit.edu> I really like the fact that clicking on a compilation error in Project Builder opens the appropriate file and moves the cursor to the offending line. The thing is, I use Emacs for editing, and would like PB to do the same thing inside of Emacs, rather than in Edit. I tried to use PB's Preferences window to point to Emacs, but it didn't seem to work. (I tried Emacs.app, emacs, and emacsclient.) I'm tempted to write a shell script that re-routes PB's commands to Emacs, but before I do that, I was wondering if someone had already solved this problem. Any ideas? Reuven

How can I do that? You'll probably have to modify the project Makefiles. I don't know of anything in ProjectBuilder to let you do this easily.... As an alternative approach, you could make another project directory and add symbolic links for the files you want to share. For example, suppose you have project X in directory X. Make a new project Y in directory Y, and from the terminal do something like: cd ~/project/Y ln -s ../X/sharedfile1.h ln -s ../X/sharedfile2.m ln -s ../X/sharedDirectory This done, changes in a shared file will show up in both places.

Don't use Objective-C where C is appropriate. <<EPS' soapbox>> Y'know what really drives me nuts? People who believe in this crap called "modular programming." They break up their code into little pieces, each no more than about a dozen lines-- and those primarily consist of procedure calls. What do they get? Lousy performance. (1) They pay a lot just in call overhead; (2) they almost completely negate the benefits of instruction caching and pipelining; (3) as code size grows, they start to see pathological VM behavior. OK, (3) can be mollified by link optimization. (2) is pretty much beyond hope. (1) is the killer for Objective C because too many newbies think that methods are a substitute for all procedures!!! How many times have you seen - (void)foo:(int)bar { spam=bogotify(bar); } // ... [self foo:mumble]; when static void foo(struct Whatever *self, int bar) { self->spam=bogotify(bar); } // ... foo(self, mumble); would have worked just fine? And worse, they try to rationalize the former as being "prettier" or "more elegant." Hogwash! It is *not* the job of the compiler/optimizer/linker to outguess your intentions. The old adage "garbage in, garbage out" still applies. If you want fast, efficient code, write it! Objective-C isn't broken. It's appropriate for a certain class of problems and inappropriate for others. Part of the beauty of the NEXTSTEP environment is that you can mix and match different paradigms to capitalize on the strengths of each. If you think Objective-C is a panacea, you are seriously unclear on the concept. It's just one tool in a big chest. -=EPS=- -- All "full lifetime warranty" Craftsman tools double as hammers.

It has several shortcomings that I would like to fix. I also hope to expand it to be able to extract the music digitally through the SCSI bus and either record, play or both. However, I am having some problems. I will probably be able to build a CDPlayer replacement, but I do not understand it all. I am using the NeXT SCSI example and the source from play3401 to do this. Basically I need pointers to documents on the commands that SCSI CD-ROMs respond to and their response to those commands. Since there is a standard (except extracting audio through the bus), there should be a document somewhere. I also need the layout of audio CDs. What is there file structure? If anyone knows where I can find this kind of documentation I would appreciate the help. I will also list a few of the major questions I have in case anyone knows the answers to these specific things. - How can I find out if there is a disk in the drive. I can send it a spin up message and then check the error fields but I would rather have a command that is a no-op. - Is there a quick and easy way to discover what kind of disk is in the drive. Is it an audio or data? - How can I search the SCSI bus to find the CD-ROM(s) that are connected? I can do this now by opening all the /dev/rsd?h files, but I do not like this. Preferably I want to be able to find the drives even across multiple SCSI host adapters. - How can I make sure that there are not any other programs trying to access the drive at the same time I am? - Right now the program has to be run under the root id (either by root or set uid). Is there a way to do this without being root? This isn't that big a deal to me. I would greatly appreciate any help.

But there is enough variety in languages that if you need a feature, like fast dispatching of methods, some language can probably do it for you. And it is good to know what is available.) To summarize: objective-C gets its style from dynamic binding. Polymorphism is important (at the center) of what objective-C does. In C++ static binding is the default, and the "virtual" keyword yields dynamic binding. I wrote an objective-C work-alike, complete with runtime support. It is a translator. Unfortunately, I'm away from school, and I haven't loaded it up yet... :-( If you don't need the "C" syntax, may I suggest two other languages. Modula-3 is an excellent system with support for inheritance (not sure about multiple, don't thing so), threads and generic parameters. There is a freeware implementation that runs under bsd unix (long filenames) and converts modual-3 to plain C. See "comp.lang.modula3" Their slogan "Modula 3: safe and effective." The other language is Eiffel, first presented by Bertram Meyers. This excellent language has method pre- and post- condition checking, as well as class invariants (assertions which must be true on entrance and exit to all methods). This language was designed by a scientist for Better Programming(tm), not by engineers doing systems work (K&R did a fine job and I use C often), and not by a committee. See "comp.lang.eiffel" Bad part is implementations must be precise: which is great for the programmer, but bad for the compiler writer.

[..] >2. Maybe the compiler should try to do this anyways if it can > if an "optimization" flag is set. The famous example is you have some geometric figure, and you want to ask it to return its enclosed area. Sqaures, circles and irregular polygons all compute differently, and not much can be shared. In C++ you jhave a virtual method, and there is no more discussion. Eiffel has an optimize option that at compile time decides if inlining is possible, given which classes an object might be at some given point in the code, taking into account which class overrides a method. C++ does not "examine all your code including libraries and then make decisions," it's just a sophisticated text translator... Objective-C doesn't either, but relies on runtime to dynamically see what is has, and then make the right decision (over and over again, each time the method gets called). To write some preprocessor to grok this for your application might prove troublesome. It would be slow, and would have to re-generate information the compiler builds itself. Also, what is the label stored in the object file for the method "(float) getDistanceTo:(id)" in the class StellarGalaxy? The compiler knows this one for sure. An optimization I've heard about is to "hide" a little structure at each method invokation (ie, each square-bracketted expr). It holds the *class* of the last object that was messaged, along with a pointer to the code. Profiling has shown that for a given HLL statement, the class of object that is messaged there, is usually the same as the class messaged there on the the last attempt... So, if the class of the current object matches that of the last object, the code which does the method is therefore known and a direct call is made. Otherwise, a search must be performed, and the little structure is updated. For example, the method getAtomicWeight is usually performed on an object of class PhysicalAtom. This can speed up loops. Objective-C has the notion of typing an object when it is declared. This hints to the compiler which methods are legal, and given enough information about which superclasses wil lbe linked in, the compiler might be able to generate direct calls. Of course, if you modify a *superclass* to now intercept a message where before none of its child classes had, then that direct call just bypassed the software change! :^| >Wouldn't this partially diffuse the static/binding >debate in objective-c's favor? > >If I am all wet, so be it. You're not all wet, you're just curious.... :-) For each problem, the right tool should be used. From the C++ programs I've worked on, I advise if you are building an application with minimal reuse, C++ can be a fine language. One big makefile to correct inheritance/polymorphism changes. If you have lots of physical RAM, Eiffel can generate correct programs after a long startup code investment, but pays off in the medium run (user enhancement time). People have said Eiffel can be learned in about the time to learn C++ completely. If you're just not sure, try Smalltalk, a LISP, or objective-C. Some one said Smalltalk is easy for COBOL programmers to use because it is so wordy (but in a familiar way). It is the first of the month and the newsgroups should be posting FAQs. Many of them talka about a language's pluses and minuses. >Mark Stankus --- brian witt -- ============================================================================= !

NeXT's documentation is inaccurate. It says in NextDev/GeneralRef/08_InterfaceBuilder/IntroInterfaceBuilder.rtf: "... So, when such a connector object receives an establishConnection message, it sets the source object's outlet to the destination object and if the source object's outlet is named target it sets the source's action to the destination's action method." It is not sufficient to have a "target" outlet. In addition the custom class has to have the following methods: - target; - setTarget:s; - (SEL)action; - setAction:(SEL)x; Having done this I was able to set up target/action connections for my own classes exactly as I always did it with controls from NeXT's palettes.

Or.... use C++ where speed is an issue, and use Obj-C everywhere else. The good thing about NeXTstep is that the compiler can do both.

I was unable to answer, because I have never wrote a driver for NeXTstep. The board is very simple, it can be addressed in several places in IO memory and it can respond to several hardware interrupts etc. So basicly, all I have to do is to write some config values to IO ram and then read the measurement data from there. Any ideas how to do that under NeXTstep486? Are there any code fragments available of such driver?

I suspect this is what CDPlayer.app does, and it's one of the things I am very intent on changing. Doing that causes the CD to stop playing if it was already in there and playing. Instead of that, try doing a playbackstatus command or a readsubchannel "current position" command. These will tell you if there's a CD in there and already running, without interrupting it if it is. > - Is there a quick and easy way to discover what kind of > disk is in the drive.

I'm not enough of a unix guru to know this part yet. It seems that you can't do an open on a CD-ROM drive unless there's a disc in it, and you can't do the identify without doing the open (unless I'm missing something there). I suspect there's a way to do this by using the generic scsi devices of /dev/sg*, but I haven't investigated that yet other than reading a few man pages. > - How can I make sure that there are not any other programs > trying to access the drive at the same time I am? I don't think you can, so I'm assuming I have to write my program such that it won't care if some other program does something with the device. > - Right now the program has to be run under the root id > (either by root or set uid). Is there a way to do this > without being root? This isn't that big a deal to me. I'm hoping to split the application apart, the way Scott Hess split apart Stuart and slog. Have all the priviledged commands in a setuid root program, and have the rest of it be able to run as the user. I haven't done *that* yet either, and the initial version will probably have to run as root too. I am at least using seteruid() calls to flip between being "root" and being the regular user though, so only the parts that have to run as root will be running as root. I consider this a very important issue, as no one should pick up an object file off the net and blindly run it as root. Thus I always give out the source for programs which need to run as root, and if I make this application snazzy enough then I might not want to give out the source code to the snazzy GUI part. And other people will probably want to write their own snazzy GUI part, and it'd be nice if all such programs could use the same code for the stuff that needs to be done as user root. Actually, what would be nice is if NeXTSTEP had more support for the handling of audio CD's, so programmers could get the functions of these special SCSI commands without having to be root to do it. -- Garance Alistair Drosehn = gad@eclipse.its.rpi.edu ITS Systems Programmer (handles NeXT-type mail) Rensselaer Polytechnic Institute; Troy NY USA

They even throw in some useful fuctions to play, read table of contents, etc. But (!!!!) beware: NeXT made a booboo in these examples. They will not work on intel machines. It seems as though they use bit field structs all over the place. You will need to go in and make these bit fields more portable. I started to do this, but found that it is easier to hack it out by hand using an array of unsigned chars. Poke the scsi ops in this array and pass it to the scsi driver.

AfsSecurityKit The AfsSecurityKit provides read, write, and execute privileges to user interface objects in NEXTSTEP applications. The AfsSecurityKit is used to turn the view of a particular set of data on or off for users. For example, the AfsSecurityKit may be used to hide a box containing financial data objects for user Bill while user Bob only has read privileges and Jerry has read and write privileges. The standard set of objects bundled with the kit allow security privileges to be set on Windows, Panels, Boxes, and Buttons. As with the appkit, developers can create their own custom security objects. Administration of security is accomplished with an interface from within your application. Security is designed to be manipulated by a designated administrator. Securable objects have their defaults set using interface builder inspectors, but may be altered at run time. Each valid application user has a corresponding AfsSecurity object which records differences between securable object's default security states and user settings. The security administrator sets the user's states, which are then saved in a HashTable. Non-administrative users may not set security values for any objects. The security flow for most objects is trickle-down: if a controlling object and its subordinates want security, the controlling object has the opportunity to indirectly restrict the security of subordinates by restricting its own security, or by directly setting security for subordinates. Typically, subordinate objects will not receive less restrictive security than the controlling object. Retail price: call Educational price: call Availability: Alpha No runtime distribution fee. OS version requirements: NEXTSTEP 3.0, 3.1 Available immediately for both the NeXT Motorola-based environment, and for NEXTSTEP running on Intel-based 80486 and Pentium computers.

I didn't want to change the whole structure of the sources, so I must incorporate the original unix makefile into the ProjectBuilder maintained makefile. To do this I included the main nethack makefile in makefile.preamble, added new dependencies to OTHER_PRODUCT_DEPENDS and all the nethack object files (that are made by these additional dependencies) to OTHER_OFILES. So the real nethack gets compiled with the new dependencies and can be linked against the Nethack Application. However, if I change an internal nethack source the application makefile tries to make the appropriate .o file before the new dependencies get any chance to make them first. So, how can I prevent the ProjectBuilder makefile from compiling these OTHER_OFILES? I only want them to get linked into the main program, as only the original makefile really knows how to handle them. Is there any other way to incorporate these .o files into the linking process?

Everything compiles into object files beautifully, but when the linker (ld) tries to link them into an executable, it reports that symbol _end is undefined. I inserted a -y flag (to tell me which files a specified symbol appears, the symbol`s type and whether the file defines or references it) in the Makefile, and it produced a pointer to malloc.o. Malloc.c has some malloc routines, but NeXT doesn't need them. However, there are some additional routines that mush uses for memory management purposes, and one of those declares extern char end[]. Has anyone out there tried to compile MUSH 7.x under NEXTStep 2.0 (BSD 4.3)? If so, did you encounter the same problem, and what was your solution, if you found one?

DataPhile is the most popular flat-file database for NEXTSTEP. I incorrectly assumed that you were aware of it. RoseBase is a back-end SQL database that is not shipping yet but looks promising. QuickBase is also a back-end database. When I think of databases, it's from a programmer's perspective so I tend to forget that most people use a front-end. Sorry for giving you misinformation.

If your call to open looks like: m_fd = open( rawDevName, O_RDONLY | O_NDELAY ); then the system will not ask the user to insert a disk. What happens is that the open succeeds if there's a disk in the drive, and it fails if there is no disk in the drive (or no drive at that raw device address). It's also quite possible for there to be a disk in the drive without the workspace having the drive. > > - How can I make sure that there are not any other programs > > trying to access the drive at the same time I am? > > > > the os does this... Hmm. Does it? I can have both CDPlayer.app and my cd-playing program accessing the CD-ROM drive at the same time, for instance (I know I can, I've done it...). Well, anyway, I guess coming up with a program that works on NS/Intel too is going to make things a little tricker than I was expecting. -- Garance Alistair Drosehn = gad@eclipse.its.rpi.edu ITS Systems Programmer (handles NeXT-type mail) Rensselaer Polytechnic Institute; Troy NY USA

I assume this aspect hasn't changed, however.] In 7.2.3, the only reference is in malloc.c's xfree() procedure; xfree() looks like a front end to the real free() that attempts to determine if its argument might have come from malloc(), or is patently absurd (in which case it does nothing). The mere fact that this code exists gives me the creeps! However, it looks like removing the extern line and replacing end with (char *)get_end() should work in _this_ case. -=EPS=-

I want the inspector panel to contain a different set of widgets for each type of shape that it can inspect. My questions: 1. Do I want a seperate 'nib' file for each inspector? 2. Is it best to refer to all the different subviews in an inspector by assigning them 'tags' in Interface Builder and then having a parallel set of constants in my code to match those tags? Browsing through the developer documentation didn't give me much help. Does anybody know of any sample code that I could model?

It's a bad idea, anyway, to go into a tight loop to do a wait, the way you're doing. A better way would be to queue up each invocation of the sound using timed entries. Timed entry procs allow events and other messages to come through. (Better yet, you could use the Music Kit to do it.)

The name should first be searched for as an element of the NIB images, then as a file-name (like NXImage is supposed to do). I got some success, but then was really frustrated in trying to get this palette usable from several different Apps (whose source is of course in several different directories). I thought I should be able to put the MyImage.palette directory in a central place and just refer to it. Apparently a palette doesn't have the object code for the classes which support it. And the object code doesn't have the "nib" that goes with it. So - any ideas? Examples? Products? Thanks Will Russell claspac@tallis.ucsc.edu 408-459-2060

Back to the original question... If one level of indirection/lookup doesn't greatly degrade your app's performance, why not place the object in a List object and be sure to remove it from the list if freed. #import <objc/List.h> and then use the -addObject or -append when object is created use the -freeObjects method when appropriate, or -removeObject: before calling -free on the object from anywhere. When appropriate, pass the index of the object instead of the id of the object, with addressability to the list already present. ============================================ See if object still exists with the -indexOf: ============================================ The List object seems to be QUITE well thought out for tracking objects, in addition to using them as members of a list. Since it's in the common classes rather than appkit, it can easily be overlooked. Bruce Gingery bruce@TotSysSoft.com Total System Software NeXT-Mail preferred, MIME-Mail ok

A long time ago, I asked this of a campus consultant, who kindly then asked this question to NeXT. The response? That it would probably be a bad idea to use or modify the clickTables in software I was writing. Why? Because NeXT, which seems to think that clickTables are an undocumented feature (and there _is_ very little documentation on them), and thus their use or format might change in future NEXTSTEP releases, or they might go away altogether. As an undocumented feature, it might be decided that Text objects do not have to be backwardly compatible with the previous release in this respect. I have heard/read that a major re-write of the Text class is planned or has been done for NS 4.0. Helpful suggestions? The clickTables are just simple lexical analyzers (or the state machines thereto). Write a small program to write one of the clickTables to stdout, and perhaps then compare the output with what you observe as the behavior of the a Text object when you click on various characters. Write your own tiny app that just has a text-in-scrollview in a window--Edit may play with the clickTables itself, possibly distorting observations. Christopher J. Kane kane@cs.purdue.edu

MultiThreading strategy deleted ... Rather than adding a complicated mechanism for queuing requests, by far the best way to approach multi-threading is to protect atomic actions with a locking mechanism. Using the threadkit for example, you could add a member to a list in a threadsafe fashion as follows: [ aList threadLock ] ; [ aList addObject: myObject ] ; [ aList threadUnlock ] ; ... so long as all atomic operations on the list are bounded by threadLock / threadUnlock operations you are guaranteed thread-safety. The ThreadKit extends these locking semantics to instances of ALL classes as well as providing a bevy of other useful features (such as thread-safe use of AppKit classes in an extremely elegant fashion). -- Blake W.

However, I have been able to learn some more on my own. I am sending part of this to the people that have replied to Since I have received some interest I will post it here also. I know that if someone sends me email then there are several others that did not. So here it is. ----------------------------------------------------- Well, I have answered several of my own questions. I have discovered most of the documentation I need. Parts of the CD-Audio specification and all of the SCSI specifications can be found in the ansi SCSI-2 specifications. I used ftp to get them from gatekeeper.dec.com they are in the directory /.8/misc/SCSI/SCSI-2/10ctxt.tar.Z I can now tell the CD to play, eject, read the table of contents and spin up or down. I am having two problems though. I can read the audio sense page which tells the volume and where the sound is going, but I can not set those values to what I want. I can not get the MODE SELECt command to work. The other problem I am having is using the TEST READY command which sends back a NO MEDIA message if there isn't a disk in the drive. This I can't even convince the ioctl to send. I also discovered how to talk to the drive without the OS prompting for a disk. This would be a problem if there was a SCSI floppy drive or syquest drive on the chain ahead of the CD-ROM. I do not have either of these, but I assume it prompts the user for any drive that uses removable media. Anyway, If you open /dev/sg0 you can talk to it. Then use /dev/rsdxh when you want the user to insert a disk. Someone suggested creating a CD-ROM object or some kind of loadable module instead of my own replacement for CDPlayer.app. I would like to do that also, but I want a replacement for CDPlayer.app because I have wanted to use CDs with more than 15 track (65 actually) and I got tired of hitting the next track button. Then I want to add to the program to allow it to read the CD through the SCSI bus and play the sound as well as record it to disk in the ".snd" format. I think the user interface will be easy and I hope that I will be able to make the object driving the CD-ROM as generic as possible. Things I still need to do. - Fix the two problems mentioned above. - Find out how CDPlayer.app gets notified of a CD being placed in the drive. - A relatively quick way to find out if the CD is an audio cd. I am not really interested in dealing with the mixed audio/data CDs at this point. - How to create a thread that can read and play the disk but still follow commands from the main application. If you are interested in helping me or are interested in seeing how I have done the things that I have, I would be glad to let you see the code. It is not intended as anything more than experimenting right now (I will have to completely redo it before I write a program), but it is commented well enough to allow you to understand what it is doing.

From: cpesch@markov.fmi.uni-passau.de (Christoph Pesch) Newsgroups: comp.sys.next.programmer Subject: MenuTemplate-class ??? Date: 07 Sep 1993 13:59:02 GMT Organization: University of Passau, Germany Message-ID: <CPESCH.93Sep7155902@markov.fmi.uni-passau.de> Hi! Does anyone know anything (any documentation) about the MenuTemplate class which Interfacebuilder seems to use for its PopUpList in one of its standard palettes (the one with the buttons, customnview and so on)? (I couldn't find it with the digital librarian). And does someone know how to get the PopUpList-editor and the special kind of button-inspector for a button which is associated with a PopUpList in an InterfaceBuilder palette? (I mean the button-inspector that ask you if the list should be a popuplist or a pulldown-menu.) --- The PopUpList uses a special subclass of MenuCell for its items. Therefor I can't use the button in IBs standard palette --- If I create a PopUpList, change the matrix to use a special subclass of MenuButton and associate it with a Button-object in IB then I always get the normal ButtonInspector and can't change the items of the PopUpList in IB. I tried to use the PopUpList-Button in the standard IB-palette to create an own palette and tried to change this Button and its associated PopUpList directly (setting up a new prototype-cell for the matrix, remove all items and add new ones). But I got run-time errors, because this Button is associated with a MenuTemplate-object instead of a PopUpList which doesn't respond to all the messages a PopUpList responds to (especially it can't free and add items). Then I tried to change the matrix of the MenuTemplate-object directly. I removed all rows, freed the cells and added new rows with the new MenuCell-type. I selected one cell, set the title of the associated button to the title of this cell ... and got runtime errors, because messages were send to the freed cells. If I remove all rows but don't free the cells then it works fine but it is an awful hack (I think), because I don't know what happens to the removed cells. Any better solutions? Thanks to everyone who has suggestions or solutions for me! Christoph Pesch (cpesch@markov.fmi.uni-passau.de)

Send your favourite ftp client off to adaptec. Here is the latest I have: The following utilities a have been designed to run on the AHA-154x/1640 Adaptec SCSI Host adapters. They only run under MS-DOS. These programs are being provided free and were written by an individual(me). If you have any complaints, then send them to the bit bucket. If you have some suggestions, then E-mail them to neese@adaptex. If you call our factory and ask questions about these, you will get a big, "I don't know what you are talking about!" If you use these programs for anything other than your on use, then give credit where credit is due (Roy Neese). Any time a file changes, I will put a date in the appropriate section. The current date is 10/11/1989. The updated files will show themselves as follows: ~/GETDEVS.EXE.Z UD 10/12/1989 So if you keep the old list you can tell which files have been updated from the last time you requested them.

This is a quickie utility that displays all of the targets and luns on the SCSI bus. No command line options, just run it.

They will display information graphically, thus requiring at least a CGA Monitor. They all have the same command line options. (Nothing fancy here) For instance, gread 1 2000 gread 1500 gread 0 3000 gread 2 gread 2 4000 The above examples are all valid. If the first argument is a single digit it can be: 0 - test drive zero only 1 - test drive one only 2 - test both drives The larger number, tells the program the range for the transfer rate in KB. Defaults are [test drive zero][1000] None of the programs will destroy data, including gwrite. GRDRIVE does both reading and writing for one drive only and thus will only accept 0 or 1 for single digit arguments. GREAD/GWRITE does read /write tests for one or both drives. All of the programs go through the BIOS and will run on any hard drive. At the end of the run the program silently waits for you enter data concerning the configuration and then pressing <ENTER> will exit. If you have your favorite graphics screen dump program loaded, then you can print the results to a printer. WARNING: GRDRIVE and GWRITE read and write the data read during the test. If you reset your computer to exit these programs, you could blow your boot track. To safely exit while these are running press <CTRL><C>. DO NOT press <CTRL><BREAK>. The programs will exit when it is safe to do so. ------------------------------------------------------------------------------- ~/SCSI.EXE.Z V6.0 Size: 37507 Oct 11 09:12 SCSI.EXE.Z UD 12/08/1989 V6.1 Size: 37466 Dec 18 09:05 SCSI.EXE.Z - Corrects program to work on machines faster than 20Mhz.

It is menu driven, and after choosing a selection from the main menu you may press '?' for further help and/or an explanation of what you are about to do. This program has knowledge of the following drives, but can be used with virtually any SCSI device (I think??).

Seldomly, more flexibility of ObjC dynamic binding has been asked for. I'd love to see *user costumizable* message dispatch in ObjC ... Such Meta-programming would enable us possibilities as: - encapsulators (trickers, monitors, pre/post conditions ..) - pre/post condition checking - new debugging tools (statistic/sequence of msg sending ...) How often (during debugging) wouldn't you have liked to know which messages gets send both TO and FROM a SPECIFIC object and in which sequence ? I often, especially while trying to figure out what a NeXT or third party (no source code) object REALLY does ... I can think of two ways to achieve *user costumizable* message dispatch 1) At a per runtime basis: - Invoking messengers objc_MsgSend* through pointers to functions rather than directly as functions (pay a bitalways) - Enabling linking of second (debugging) objc_Msg* messengers used as function envelopes for messengers invoked through pointers to functions (pay as you play) Then we could implement a variety of our own messengers, install them dynamically into the ObjC runtime and switch between them as needed. This would be very usefull during development. 2) At a per object basis: (Woow) - Add a Meta-object reference to the Object class alongside isa. IF an object (domain object) has a meta object attatched, then pass all messages to this meta object instead of directly. Reaching the domain object is meta-object responsibility. (pay a bit always and more when you play) Such meta-objects could do filtering of message passing, fancy forwarding and take second/third actions also on other domain objects alongside. All this in a *user costumizable* fashion and WITHOUT clutting the code of domain objects (as forward: do). So all Meta-stuff can be turned on/off simply by tatching/detatching meta-objects.

For another, if you upgraded, rather than reinstalling, the old defaults may be the problem; look in the release notes about blowing them away. Lastly, you could try setting the timer to a smaller value: dwrite loginwindow TimeToDim 180 for three minutes (the value is in seconds).

And as is so often the case with such projects the main remaining problem is that both the Appkit and this application absolutely insist on having their own main event loop. Now, as you can't have two of them in a single thread, going multithreaded is of course an option, but considering how un-threadsafe the Appkit is, I'd prefer not to. So instead I'm trying to avoid using [Application -run] entirely. Unfortunately it seems that [Application -run] still does so much magic that avoiding it entirely will not work. Instead I concocted the following scheme: @implementation MyApp:App - appDidInit: sender { [self stop:self]; return self; } - runAWhile { NXEvent *ev; running=1; while(running && (ev=[NXApp getNextEvent:NX_ALLEVENTS waitFor:0.0 threshold:NX_BASETHRESHOLD])) [NXApp sendEvent:ev]; return running ? self : nil; } - waitEvent { NXEvent ev; [NXApp peekNextEvent:NX_ALLEVENTS into:&ev waitFor:NX_FOREVER threshold:NX_BASETHRESHOLD]; return self; } @end void main(int ac,char *av[]) { [MyApp new]; [NXApp run]; while([NXApp runAWhile]!=nil) [NXApp waitEvent]; [NXApp free]; exit(0); } Contrary to all expectation this actually works perfectly well. The program behaves just as if it was using the genuine main event loop, but instead it returns whenever it runs out of events. In this shape I can integrate it into the other main event loop. All I still need is a method of having a signal sent to me or a file descriptor become available when an event is waiting, but that should be a fairly straightforward proposition (though I appreciate suggestion for that too). Now the question is, how safe is this construct ? Will it break something ? Should I go through the _freelist in each iteration of the fake event loop and free everything in it ? What other magic does [Application -run] do ? In particular, it seems it also messes with the signal handlers on entry and exit. Can you turn this off/replicate it ? Even partial answers to any non-empty subset of these questions will earn my undying gratitude. Carl Edman

What I would like for the compiler (actually the preprocessor) to do is generate a "listing" of my source, including all included/imported files, with or (optionally) without macro expansion. I want it to show conditionally compiled code in such a fashion that I can look at the listing and tell what would be compiled and what would not (that is the real motivation behind this question). The compiler I am used to has these features; As far as I can tell, gcc does not. So, is there a way to get (g)cc or cpp to do what I want? Or, has someone possibly written such a beast as a separate program? I know that I can get the source for gcc and hack the preprocessor to do what I want, but maybe someone else has already solved this problem.

The problem is that some of the objects report errors via alert panels -- and if you get an alert panel in a program in the middle of your "night run", and there is no one there to click "OK", then the entire batch job stops in the modal loop. Has anyone else out there faced this problem? What did you do about it? You would think this is a classic time to subclass something, but NXRunAlertPanel() is a function, not an object message, and unless there is something out there none of us have discovered yet, you can't override a function. We could also write another function with another name and then substitute that function name for NXRunAlertPanel() every time it occurs (a pain, but not impossible), but then the question is: how do you tell if the program has been run in batch mode? Is there something I can look at that will tell me this? Any ideas will be gratefully accepted... cathy :-) ---- cathy@scarolina.cerfnet.com

A good question on which there is much confusion, because the AppKit is not consistent (surprise!). For most Application delegate methods, if there is no delegate or it it does not respond, the Application is given a chance, too. That way delegate methods will get sent if they are defined in a subclass, which is what Carl was doing here (MyApp:App). TextFields operate the same way. If your TextField has a delegate and it responds to a method, the delegate gets the message. Otherwise the TextField uses its own implementation of the method. (Remember, these delegate methods actually originate in the Text object, so TextField is always in the process of forwarding them.) Windows, on the other hand, are documented as NOT giving any object other than the delegate a chance to respond. They are also very generous with perform: methods. The tryToPerform:with: method is overridden in Window to allow all such messages to be handled by the delegate. And they wonder why newcomers to NEXTSTEP get confused... 8^) -- Gregory H.

In that case, you need to include a [allInstances addObject:newObject] message in the awakeFromNib method, too. Second, there is a memory leak in the code. The +initialize method should be implemented as follows: static id allInstances = nil; // statics must be initialized ... +initialize { if (allInstances == nil) allInstances = [[List alloc] init]; return self; } It is possible for the runtime system to call +initialize more than once, in which case a new list gets allocated each time. If this happens as the result of a subclass getting initialized later in a running program, you would lose track of existing instance records, as well as a cluster of unrecoverable memory. -- Gregory H.

[rest deleted] This raises the more general question: What is the best way to tell, from within an object, whether or not I'm running in an app? I have a kit of objects that does not use the appkit (all objects in the kit descend from the common classes only), and it's conceivable that they could be used in daemons or command-line utilities or whatever, where the appkit is not in use. If I want their behaviors when not in apps to be different than when in apps (for example, writing a message to stderr vs. using NXRunAlertPanel), how can I distinguish between the two situations? Is it better, since none of the objects descend from appkit classes, to assume that they are not running in an app, and just set up hooks (like methods to be overridden, callbacks, etc.) so that subclasses of these objects can implement appkit-dependent behavior?

This has never worked. I reported it directly to Jean-Marie on the order of a year ago. He admitted it was a bug, but wasn't specific about a fix date. By the time you get into init or awake you know whether or not you're in IB, though. It's pretty easy to workaround.

Whenever a user edits a field, the window's field editor (an instance of Text) is used to perform the actual editing. Okay. So user clicks in a field, and the field editor becomes the first responder. So when the user sets the font in the font panel, the field editor NOT your view is the first object to receive the changeFont: message. (I'm not sure if Text forwards changeFont: up the responder chain.) So how do you keep random objects such as fields from receiving changeFont:? Well, you can't unless you want to mangle the responder chain. However, what you can do is tell the FontManager to send a different message instead of changeFont:. That is done with - [FontManager setAction:]. Your view implements the new method instead of changeFont: and you don't have to worry about mangling the responder chain. So far so good. However, how and when do you restore FontManager's normal behaviour? If the FontManager is sending this new message, none of your text fields are going to be updated correctly when the user changes the font. Hmmmm... well what I'd suggest is setting your preference panel's delegate. When the preference panel becomes key, set FontManager's action message. When the preference panel resigns key, reset the FontManager's action message. In the preference panel's delegate... Add the following instance variable: SEL fontManagerAction; Add the following two Window delegate methods: /*** Window Delegation ***/ - windowDidBecomeKey:sender // Sets the FontManager's action to setPreferredFont:. // Saves the previous action. { id fontManager = [FontManager new]; fontManagerAction = [fontManager action]; // Save default action. [fontManager setAction:@selector(setPreferredFont:)]; return self; } - windowDidResignKey:sender // Restores the FontManager's action. { [[FontManager setAction:fontManagerAction]; // Restore default action. return self; } ---------- In your custom view... Rename your changeFont: method to the following: - setPreferredFont:sender { } Modify setFont: as follows: - setFont:sender { // [window makeFirstResponder:self]; // Unnecessary. [fontManager orderFrontFontPanel:self]; return self; } The above should work. (I've never done this before... this is untested... good luck!) : 2.

Similarly design non-appkit-based objects to assume NEITHER that they are being run in an .app nor not.

It's even simpler than that: Makefile.preamble: PRECOMPS = fookit.p Makefile.postamble: fookit.p: $(HFILES) There should be a file, fookit.h, that #imports all the headers in HFILES, and you're done. If you want to leave out some of the headers, just list the ones you want and #import the same ones in fookit.h. Since there's already a .h.p rule in the NeXT-supplied makefiles, it just works. For example, if foo is a library project, this will make a precompiled header for the entire library, properly named. No other headers will be precompiled, which is good because .p files are _huge_. And if you're really concerned about space you should only make fookit.p when you're ready to install or ship the library, and delete it when you're done. Actually, if you're going to always name your libraries after the project name (e.g. a project named fookit will always produce libfookit.a and fookit.p), you can make the above rule generic for any library like this: $(NAME).p : $(HFILES) I've done this, and put the rule in a central MRPMakefile.postamble that I always -include in every Makefile.postamble in every project. Then I don't have to think about it. You can even leave out this rule, and whatever you define in PRECOMPS will compile every time, I think, though that's rather undesirable. Either way you do have to modify fookit.h every time you add a new .h file. Thanx, Michael -- Michael Pizolato gnihtyreve noitseuq Michael_Pizolato@afs.com NeXTMail appreciated

If the symbol isn't there, then the program won't even link, and the above code can't work. Although, I guess you're saying that in your example such a modification has been made. >-> Is it better, since none of the objects descend from >-> appkit classes, to assume that they are not running >-> in an app, and just set up hooks (like methods to be >-> overridden, callbacks, etc.) so that subclasses of >-> these objects can implement appkit-dependent behavior? > > My personal opinion is that it is NOT better to assume >anything :-) which is beyond your control, or could be beyond >your recollection. Well, I didn't mean assume so much as this: design all objects that do not descend from appkit so that they _never_ try to use appkit stuff. So, your showError: method above wouldn't invoke NXRunAlertPanel because that's an appkit thing. Then if you want to use the object in an app, you'd have to either subclass the non-appkit objects and use NXRunAlertPanel, or deal with errors from the non-appkit objects in another way. If the latter, then the non-appkit objects should be designed to return specific, documented values to indicate error or other conditions requiring special treatment, so that in an app the callers could deal with errors in an appkit-friendly way. >Possible solutions: > > Design non-appkit-based objects to assume NEITHER that they >are being run in an .app, nor not.

If you're designing objects that descend from common objects only, and they're not intended to be additions to the appkit but instead are extensions of the common classes, IMHO you should not build any of this "Am I running with appkit or not?" kind of code into the object. They're not appkit objects, so they should not even acknowledge the existence of appkit. The same would go for a new appkit object that might act differently if, say, dbkit is linked into the app or not. In that case, it's an appkit object, and it should not even acknowledge the existence of dbkit in its implementation. The programmer who is writing the program, app, or kit that uses both should resolve the behavior changes in subclasses or other objects.

The remainder of this article is the proposed chapter outline. I welcome all comments on whether the material is complete, germane, and properly organized to the task at hand. Thanks in advance for any ideas you care to share. ========================================================================= NEXTSTEP Programming: A Master's Class Chapter Outline Introduction The focus of this book is on real-world business problem solving with NEXTSTEP, primarily AppKit and extensions. Prerequisite: Garfinkel & Mahoney or several months of hands-on experience. Every chapter provides an insider's look at some aspect of the runtime system and AppKit classes, with a concrete example to reinforce the concepts. By the end of the book, you will have the spine of a multi-form application with swappable inspectors, a sophisticated new user interface control to replace PopupLists, and a palette that provides access to your application from other applications through distributed objects. Chapter 1: Getting Organized Programming with object technology is different from traditional methods. No matter how well you understand the technology discussions that follow, your experiences will be less than satisfactory if the work is organized poorly. Outline new approaches in the following areas: workgroup composition, division of responsibilities, determinants of compensation. Chapter 2: The Teachings of InterfaceBuilder Premise: InterfaceBuilder is a great example of open-ended design. How the "application as transactor" paradigm provides flexibility. Multi-document and multi-form applications. Leveraging from existing ObjectWare. Models, Inspectors, Finders, Views, and Data Sources: portability and flexibility in action. @protocol: Planning for reuse. Chapter 3: The Objective-C Runtime System and Common Classes Dynamic binding is your #1 pal. Designing applications that are intended to be assembled at runtime and not one second earlier. Available runtime functions and how to use them effectively. Categories and when to use them instead of subclasses. Warnings with multiple categories. Project: Using HashTables to implement class variables. Chapter 4: The Application Class Describes the internal operations of the Application class and optimal strategies for building subclasses and delegates. The role of the application object as central coordinator and how to make the most of it. Project: The spine of a multi-form application with an inspector. Chapter 5: The Window and Panel Classes Describes the event and View management provided by these two key classes, with optimal strategies for building subclasses and delegates. How the NeXT-supplied panels (Font, PageLayout, Print) emphasize good design practices. Accessory views. Popups are Windows, and you shouldn't use them as controls. Project: Panel subclass that will be the base for a swappable inspector, with Popups used in the intended manner. Chapter 6: The View Class Hierarchy View management. What happens when you display, and how to optimize the results. Changing the subview hierarchy to rearrange back-to-front order. Project: SwapView for the inspector. Putting the SwapView and the SwapPanel on a palette. Chapter 7: The Text and ScrollView Classes What Text can and cannot do. How Text serves the Window and Control classes. All those funky tables and what they mean. Do-it-yourself pagination. Managing Text in a ScrollView. Project: Contents Inspector with a scrollable Text object. Chapter 8: The Control and Cell Class Hierarchies Describes how these two apparently disparate classes are combined into the primary UI objects. Goes into detail about how the most common objects are constructed, with the goal of teaching how to subclass new Controls effectively. Project: LookupField, a new Control to replace PopupLists, with all override methods demonstrated. Build a custom palette for this object, with its own private IBConnector and IBEditor. Chapter 9: The NXImage and NXCursor Class Image management. Animation. Cursor rectangles. Project: Designing and implementing a custom cursor for the LookupField's button area. Chapter 10: The Matrix, NXBrowser, and (DB)TableView Classes Complex controls and how to design them. 50 ways to fill your browser. A method to refocus a browser through a TextField. Using Drag-and-drop to add and remove items. Project: A multiple selection inspector. Chapter 11: Distributed Objects What are they and how do they work? Synchronous/async messaging. What are Portable Distributed Objects? Project: Designing a simple client/server process with distributed objects. Extending the server side to be multi-threaded. Chapter 12: Inter-Application functionality What the application already knows how to do, how you can extend it. Talking to Workspace. Designing a good API. Allowing your app to be extended vs. giving other programs a chance to talk to it. Services provision. Project: Using a non-View palette to deliver the functionality to other programmers. Chapter 13: Performance Considerations All of these are brought up in the rest of the text as appropriate; this is a summary for quick reference. Common PostScript errors. Memory management. -- Gregory H.

I like this however, : can you please give me a tangible explaination as to why this is such a : desirable approach? : : ie. why go indirectly thru first responder to file owner rather than : directly to file owner. : In most multi-document applications (such as Edit, Draw, Workspace Manager, IB), there are at least two realms of responsibility. One is the responsibility for the application as a whole. For managing the menu, for handle service request, for creating new document. The second realm of responsibility is over the individual documents. Each document is a stand-alone unit, operationally independent from the rest of the application. (Meaning, it's able to perform most of its work without having to call on other documents or the application itself.) In a well written application, well written meaning an application that enforces strict separation of realms of responsibility and conforms to other object-oriented guidelines and principles, creating a new document can be as simple as "newDocument = [[Document alloc] init]", a single method. The responder chain provides a way of separating the application realm of responsibility from the document realm of responsibility. By connecting your menus to responder you are making the application realm indepedent of the implementation of the document realm. You can change the menus without effecting or having to perform any work on the document realm. You can change the interface, or the code in your document realm without effecting or having to perform any work on the application realm. The only thing that's needed is some agreement between the two realms on what methods, what protocol is to be used to communicate between them. Here's a real world example. Cut, copy and paste. Imagine if you had to connect the cut, copy and paste menu items to each and every interface item in your document. Further, if you wanted to create a new document, or close a document, you'd have to modify each and every connection. Also, when the window changes you'd have to modify each and every connection. Instead the responder system is used. Whatever the current responder is, regardless of the window or interface element involved, it receives the cut, copy and paste messages. Also notice that this relies heavily on polymorhphism, the ability for several objects to define and implement the same methods. As long as an object can handle cut copy and paste, it just works. Notice that it is the responsibility of the receiving object to handle the message. The sending object, in this case the menu, isn't responsible for, nor does it care about the implementation on the receiving end. So why route target/action message through the first responder instead of file's owner? Because it enforces a strict separation of responsibilities in your application. And this in turn means that your application is easier to maintain, and it also enables your application to support multiple documents, inspection systems, and so forth with less effort than a conventional approach. ----- I hope you were able to glean something out of this. It's kinda hard to discuss object-oriented programming, principles, and methodology sometimes. The important thing to take from this is to try to think of your application in terms of responsibilities. What are the realms of responsibility within your application? Who is responsible for what? Who should be responsible for what? And then once each object is an expert in its particular field, develop interfaces between them so that they can communicate. For example, Controls in all their various forms and flavors are responsible for editing and displaying a value on screen. Yet despite their complexity they have a simple interface, setStringValue:, stringValue. That's all the rest of the world needs to know about them. And so if you have a problem with editing, or display, you know exactly who is responsible, and where to go to make the change. Well enough. Hope this was of use. 'Los

I think (i.e. the following is untested but should be correct) that the thing to do is to use setValueFor::from: or setValueFor:at:from: (defined by the informal protocol DBTableDataSources): Given: id aTableView - the table view in question. int row, column - the row and column of the cell you want to change. const char *textValue - the new text value. id dataSource = [aTableView dataSource]; id newValue = [[DBValue alloc]; // Set the value of value to the text value. [newValue setStringValue:textValue]; // Note: Following assumes columns are static (fixed number of), and // rows are dynamic. If the reverse (columns dynamic, rows static), // swap variables row and column. [dataSource setValueFor:[[aTableView columnAt:column] identifier] at:row from:newValue]; ---- Explanations: When a DBTableView is connected to a database, the table view's data source is a DBTableAssociation (undocumented subclass of DBAssociation) that conforms to the DBTableDataSources informal protocol. The DBTableAssociation acts as a go between for the table view and the record list the table view is displaying. Whenever a change occurs in the table view, the DBTableAssociation (data source) is notified (via setValueFor::from: or setValueFor:at:from:). The DBTableAssociation then updates the record list with the new value. 'Los

The richness of a language and the method of writing that language impact your expressiveness. With RTF I'm able to be much more expressive than with straight ASCII. I can use bold, italics, real open and close quotes. Some may dismiss this is just prettying things up, but bold and italics and all that do impart additional information. They do have meaning outside of appearence. Imagine if the NeXT documentation where written in Man page format? Imagine if the New York Times or magazines or any other literature was written in the stodgy courier / ohlfs fonts. You'd lose something more than just appearence. I will agree with Louis Mamakos that there are more important things for NeXT to work on than supporting RTF code. However, I gratefully accept any improvements NeXT makes. It's better than nothing which is what everyone else is doing. That's my nickel. (Inflation). Send flames to comp.sys.next.advocacy. 'Los

IT works fine for displaying but I have trouble field. IDeally, I want to validate the value before I commit it to the database and if the commit fails, the value should not change and the selection should not move on. From the documentation, I have concluded that I need to use the setValueFor: identifer a:(unsigned int)aPosition from:aValue to validate the input and then use setValueFor:identifier at:(unsigned int)aPosition from:aValue to actually commit the value to the data source. My two questions are: 1. How does the formatterWillChangeFor:at:to:sender method work According to the documentation, this method is invoked before the value is changed. I'm using a Controller class which I've set up as the delegate of the formatter of each column of my DBTableView. The delegate (Controller) never receives a formatterWillChangeFor:at:to:sender message, however; I'd expected this message to be generated each time the user edits a field. Do I need to explicitly generate this message? 2. Is the formatterWillChangeFor:at:to:sender generated before the setValueFor:identifier:at:from: message? The latter is actually used by the DBTableView to update the data source. I would appreciate any help on this. Since I have difficulty reading news these days, please reply directly to alex@oolesson.com. Regards, Alex

Again, always willing to display my misunderstanding of Makefiles (I've noticed that this seems to flush out better solutions so we all win :-), I've attached a context diff that "patch" would be only too eager to apply to the original Makefile in the Bezier BackSpace view.

Note that defaults can be specified from the command line, ie. "application -Batch YES" as well as being set in the user's defaults database. Okay, that solves the batch conundrum. Now how to handle the alert panel. Well, I'd suggest writing an object to manage alerts for you. So instead of: NXRunAlertPanel(const char *title, const char *msg, const char *defaultButton, const char *alternateButton, const char *otherButton, ...) you'd have: [[AlertManager new] title: message: defaultButton: alternateButton: otherButton: otherArgs:]; This object would check the Batch default, and if NO the alert object would display the alert panel. If Batch is YES, it would log the alert. You're gonna probably need to add support for alert severity - warning, assume yes, assume no, wait for user (email alert?), fatal. Well it could get pretty hairy. Depends on what you want to do. Anyway that's how you should (imho) do it. Good luck! 'Los

NXArgv[0] is the name of the executable if launched from the command line but is the full path of the executable if launched by Workspace. So if NXArgv[0][0] == '/', the app was launched by Workspace. There's no need to add yet another defaults variable because NXArgv is a global variable and thus is available from anywhere within an app. -- Art Isbell Cubic Solutions NeXT Registered Developer NEXTSTEP software development and consulting NeXTmail: art@cubicsol.com Voice: +1 408 335 1154 USmail: 95018-9442 Fax: +1 408 335 2515

This doesn't seem like a good idea because I don't usually want precompiled headers to be built automatically from $(HFILES). Once a precompiled header is imported by a source code file, a change in one of the header files within the precompiled header would cause this source code file to be recompiled even though it might not actually depend upon the one header file actually modified. How would "make" know when to create such a dependency without the developer instructing it to do so (which is the functionality that NeXT has provided)? -- Art Isbell Cubic Solutions NeXT Registered Developer NEXTSTEP software development and consulting NeXTmail: art@cubicsol.com Voice: +1 408 335 1154 USmail: 95018-9442 Fax: +1 408 335 2515

It has the following syntax: {\myDestination and here are some parameters} The font table is an example of a destination group. Rich Text Format has a fairly well defined syntax. So if you were going to extend it with your own control words/destinations, you'd stick to the standard syntax, right? Wrong. Not if you're NeXT. That would be too easy. :-) I tried to create my own destination control word and have it recognized by the Text class using registerDirective:forClass:. But it didn't work because I was using the standard syntax for destination groups. It turns out that the Text class expects _this_ syntax: {{\myDestination and here are some parameters},} Now this is very odd. It breaks the rules. Any other RTF parser would treat that extra "," as part of the text. So why did NeXT do it this way? It's so bizarre and unnecessary I'm wondering if it was done deliberately to prevent non-NeXT editors from understanding NeXT RTF. Or was it just a cock-up? Dave Griffiths

After a while the error builds up enough to equal a pixel or two. Split-views have the same problem. If you have a split-view with several subviews and then resize it larger, and then resize it smaller (both presumably by resizing the window), you'll notice that things are not quite the same when you're done.

Objects don't exist until they are created and the only way to physically create them is to allocate memory for them at run-time. Now I know that you can create them using normal memory allocation routines (or just pointing at some existing memory) without using +alloc but I would assume that the NXReadObject method doesn't try to be quite that cute about it. Or does it (yah-hah-hah)???? > Second, there is a memory leak in the code.

However there are still two problems which can cause strange things to happen in +initialize. First, if your class is subclassed and the subclass does NOT provide a +initialize method, your +initialize method will be called to initialize the subclass. Note that if the subclass provides a +initialize method, then generally it will NOT call its [super initialize] method (at least most of the classes I am aware about do not) so providing a subclass +initialize method prevents this from happening. However you do have to guard against it. The preferred way of doing this, however, is: > +initialize > { > if (self == [ThisClass class]) { > // > // place all class initialization code here > // > allInstances = [[List alloc] init]; > } > return self; > } The code inside the outer if{} will ONLY be executed ONCE by the run-time system in any execution of the program. The only way the code could be executed again is if the program actually executes its own [ThisClass initialize] method directly. In this latter case, the if{} test for a nil allInstances id would still be necessary. Jon Rosen

So I used a sizeToFit command in my code. This *did* resize the : view as desired, but there was a problem: the old (larger) size of the : view was still visible (though partly obscured by the new size). I suppose you used sizeToFit because you wanted the Matrix to fit what the user typed into the text field cell... Anyway, the documentation specifically states that -[Matrix sizeToFit] does not redraw the Matrix. To redraw the Matrix, send it a display message. (But, I don't see how anything was drawn in the first place.) : After I thought about it this made some sense---the view was : getting a command to display itself again (after its size had : changed) but there was never any command to "erase" the picture : of itself that it had *previously* drawn. : : [Description of erasing space occupied by view.] : : Now, At last the questions: : 1) Is this more or less what you have to do in this kind of : situation? Or is there some simpler way to see to it that old : "outdated" images are not left visible? Sorry, but this is not what's done. In the first place it's not your object's job to have to clean up after the view. It is the view's job to clean up after itself. So the cleanup code, if any, should belong in the view. (Fundamental law of object oriented programming, separation of concerns. Displaying is not your objects concern. It is the views concern. The view is responsibility for displaying and cleaning up after itself.) So what should you do? Well, sending display to the Matrix should do the trick. But for future reference: if you want to display a view that is not opaque (ie. doesn't "paint" 100% of its surface leaving some of its superview exposed), send it displayFromOpaqueAncestor:::. That will traverse the view hierarchy until an opaque superview is found. That opaque superview is then sent display:::.

Why didn't this work like I thought it : would? Another lesson for the day. Don't make assumptions. What you were trying to do, which was basically correct, was redraw the view's superview. However, instead of you doing the work, you should have let the view hierarchy do the work.

NeXT time if you have a problem, stop and think how it should be done in terms of object oriented programming. In particular ask, what is the problem? and what object is responsible for this problem? By all means DO NOT start hacking something together. It is very tempting to patch things together and just make it work, but what you will end up with is a mess. Object oriented programming isn't magic. The benefits don't magically appear. You have to have a lot of discipline and do things right. In this case you should have thought - Okay, display isn't working? Whose job is it? Matrix. Why isn't Matrix displaying correctly? - and then from there you could have used Librarian to zeroe in on everything (reference, concepts, example code) having to do with displaying Matrixs.

So if I have a known superclass, and I have an unknown number of subclasses, I can't at any point in time, be sure that each subclass has been entered into my "allInstances" table. The subclass has to be sent an "+initialize" message first before it gets added to the table, which means that someone tried to allocate my class. I need to know which subclasses are out there without someone allocating each class first. If the system automatically sent a +initialize to each class object before running the program, then what you wrote would work fine. The system doesn't do this (NeXT likes laziness :-) so we're still stuck... - darcy

I've coded up a little app (based on the old Unknown app from 1.0 (or was it 0.9) days, that allows me to open files in vi from the workspace. Basically, its just an Application delegate object which knows how to open multiple files (i.e., acceptAnotherFile returns YES) and the app:openFile:type: method simply exec's soil with 'vi filename' as the -Shell argument. This pops up another Sutart window with the filename loaded into vi, when you quit vi the window goes away.

I believe there's another way for a custom object class to tell if it's running under 'Test Interface' mode in InterfaceBuilder as opposed to running as part of an application. Building an IB palette under 3.0, it appeared that when IB went into 'test' mode, it used 'read' and 'write' to duplicate the objects -- before I implemented archiving methods, my object's bit flags wouldn't function in 'test' mode. So, if you add a flag bit that doesn't get archived, then it's value can be setup to be different if it was init'd or copied and you'd have a rough guide as to whether you're runnning in 'test' mode. Yes, it's crude. - Christopher

If you are aware of accountants and/or system professionals interested in exploring NEXTSTEP programming opportunities with us, please read on: JOB REQUIREMENTS: - Knowledge of relational databases and SQL (Oracle, Sybase experience preferred) - Proficiency with graphical user interfaces - NEXTSTEP, UNIX, OOP programming experience necessary - These are permanent full time positions. Read about our the SteppingStone Unified Accounting project below: __________________________________________________________________ What Sets Us Apart? SteppingStoneTM systems are developed from the ground up for the rich NeXTSTEP environment, they are: o graphical, as only NeXTSTEP knows how; o unified (non-modular); and, o entirely user-definable. What Is Unified Accounting Anyway? Very simply put, it is good old-fashioned accounting - the way we used to do it before the initial computerization process messed it all up. We don't make you differentiate between source documents for AR, AP, etc. Each piece of paper tells a story - simply record the facts and let the computer sort it out. We Let You Configure Your Own System! With the InfraStructureTM Builder, the accountant or system administrator is in complete charge of the system structure and procedures. You, the user, are in complete control over every aspect - there is virtually no limitation. You can: o set up any number of Transaction and Master fields; o define the type, size and smartness of every field; o create simple or complex account number structures of practically any size and meaningful hierarchy; o designate any number of GL accounts as Subsidiary Ledger control accounts to handle AR, AP, Inventory or whatever; o establish Global Tables for data that is account chart independent such as a single name and address table; o create any number of data entry templates consisting of desired fields and lay them out in any format. o identify control features of source documents and Special GL accounts. Getting Data In. o document driven; o through user defined input formats including simulated forms, with or without user defined formulae; o post on a batch and/or real-time basis; o solid audit controls permit posting into current, past, or future periods at any time; o process balanced transactions to cross "borders" between different accounting periods, fiscal years, and legal entities and generate offsetting transactions; o automatically calculate allocation of prepaid and similar expenses and generate transactions into the future; o capture actual, budget, and restatement data; o the "open period" concept allows the layering of data into as many levels as necessary - "13th period", etc. for adjustments at year end are no longer needed. Getting Data Out. o graphical design of all reports; o create templates to control the display and positioning of all data in a user-defined, purpose-specific manner; o printer options: laser for high quality, or non-laser for cost effective high volume hard copy generation. Get Started Now. Version 1.0 will ship at the end of the last quarter of 1993. The first pre-release sales have already taken place and we are busy helping our customers defining their needs and system set-ups. They are planning to beat their competitors and earn pre-release discounts at the same time. You can too. Let us give you an administrative check-up, on-site. Suitability Guaranteed! SteppingStone delivers what it promises. We guarantee it, when you enroll in Mi Training Camp. If you are unable to spare your senior staff, we can help. Our trained, independent Configurators can provide on-site implementation support, on a fee-for-service basis. Forward To The Past. SteppingStone proudly re-introduces the classic approach to data entry (as opposed to the inverted approach).

[Darcy pointed out that classes can be dynamically loaded/created, so that it is ALSO a runtime issue] Have you looked at objc_getClasses to see if that might help? >From GeneralRef/15_RunTime/Functions: objc_getClasses() returns a pointer to the hash table containing all the Objective C classes that are currently known to the run-time system. You can examine the table using the common hashing functions. In the following example, NXNextHashState() gets each class from the table in turn, and object_getClassName() asks for their names: NXHashTable *classes = objc_getClasses(); NXHashState state = NXInitHashState(classes); Class thisClass; while ( NXNextHashState(classes, &state, (void **)&thisClass) ) fprintf(stderr, "%s\n", object_getClassName((id)thisClass)); I think this is probably the only way to do it. Once you have the classes, you can do a "IsKindOf" to see if they inherit from you.

The only reason I would use x/kedit is because of the neat cut and paste utilities. You can highlight a block of text that is not continuous, say one column of numbers from a file with 5 columns of data, and copy that column to somewhere else, or shift the whole column left or right or all sorts of cool things.

I do use Edit most of the time - it has some great features. I also use vi, because vi is generally faster to use and more powerfull. If the two could be brought together it would be fantastic... I can imaging a Vi which behaves virtually like edit while in insert mode, but pressing escape takes you into a Vi command mode, where all the great keyboard driven stuff can take place. A naive user could treat such an editor like Edit, never leaving insert mode, but someone with Vi experience could ignore the extra options in insert mode, and keep switching back to command mode to move around, copy/delete blocks etc. The all round experienced user could make use of both modes to the full, and get the best of both worlds.

Vi users HATE Emacs - this is fundamental, and important Excuse me, but you didn't really address the suggestion. Yes, many vi users hate emacs.

What I don't understand is what's the point of such hatred when emacs can be set up so that it works *just like vi*, unless it's purely a knee-jerk reaction? The lisp code for vip-mode comes with the emacs distribution, and can be invoked from the startup file. And since there's already a snazzy interface for emacs, you get your mouse/window setup, *AND* your vi command set, without anyone having to write anything new. -- --paul paul@whimsy.umsl.edu ================================================================= The Law, in its majestic equality, forbids the rich, as well as the poor, to sleep under the bridges, to beg in the streets, and to steal bread. -- Anatole France =================================================================

It works fine for me without the chanting. The compiler should let you know that your declarations are inconsistant, like it does if you use a different return type in the implementation than in the interface: TKObject.m: In method `tryThreadLock' TKObject.m:45: conflicting types for `-(int)tryThreadLock' TKObject.h:21: previous declaration of `-(BOOL)tryThreadLock' ... but the duplication of the declaration is 100% consistant with the way C does function prototypes.

I use both vi and emacs--vi for programming and sys admin work and emacs for typing, writing news articles, TeXing, and so forth. When I first started using emacs, I tried the VIP mode but found the many differences between it and vi subtle but annoying. So, I now I use emacs as emacs (except for some custom stuff like making TeX-buffer also update the display in TeXview--by the way, I *hate* how TeXview makes itself the active app whenever its asked to (re)display a file; this is against the UI guidelines, although a lot of apps do it). Admittedly, I haven't tried VIP mode in some years so the emulation might have improved, but I doubt it. I would argue that knowing how to use vi (or ex) is important for sys admins. When the system crashes and only comes up in single user mode (or if you are doing single user mode stuff like making secure backups), neither emacs nor Edit will be available. As a consultant, I don't know how many times I've had to tell someone how to use enough of vi to edit configuration files to get a system working properly. -ccwf Charles C. Fu

(DCI) 508/470-3870 NeXT ANNOUNCES 1994 EAST COAST DEVELOPER CONFERENCE IN WASHINGTON D.C. IN JANUARY, 1994 REDWOOD CITY, CA - September 16, 1993 - NeXT Computer, Inc. and Digital Consulting, Inc. today announced they will host the 1994 East Coast NEXTSTEP Developer Conference, January 24 - 26 at the Sheraton Washington in Washington D.C. The conference agenda will compliment the West Coast NEXTSTEP Developer Conference to be held in June concurrently with NeXTWORLD EXPO. Steven P. Jobs, chairman and CEO of NeXT, will be the Conference's first day keynote speaker. Software developers, information systems management, system integrators and independent software vendors who want to learn more about object technology are invited to attend two days of sessions and one full day of courses focusing on NEXTSTEP, NeXT's object-oriented software. NEXTSTEP integrates a system-wide object architecture with the industry standard UNIX operating system, providing the industry's most complete object-oriented operating environment. NEXTSTEP Developer provides visual application construction environment and frameworks of reusable objects for the development of client/server applications. "Everyone is talking about object-oriented technology, but only NeXT delivers a complete object solution to client/server computing today." said Jobs. "NEXTSTEP is for those developers who are not willing to wait two or more years for the benefits of object-orientation expected to be delivered by other vendors such as Microsoft." DEVELOPER CONFERENCE SESSIONS and NEXTSTEP COURSES Developers are invited to see how object-oriented design allows for the creation of more flexible and robust objects, applications and systems in a client/server environment. The conference also includes general sessions which cover debugging and performance tuning as they relate to NEXTSTEP. A lab offers developers one-on-one time with members of NeXT's technical staff. The Conference is divided into four tracks to best meet developers' needs: * "NeXT in the Marketplace" is designed to give managers an overview of the technical services and development opportunities offered with NEXTSTEP. * "The Art of Design" focuses on how object-oriented design can create more flexible and robust objects, applications and systems. * "A Closer Look" features sessions focusing on NEXTSTEP's object kits and distributed objects. * "Hardware is Inevitable" focuses on hardware platforms, system administration and configuration issues for systems engineers. * NEXTSTEP Courses Conference attendees also have the option of enrolling in four in-depth, half-day NEXTSTEP Courses. Two of the Courses are intended for those new to NEXTSTEP as they feature an introduction to both the NEXTSTEP and NEXTSTEP Developer products. More advanced Courses focus on object-oriented design and Portable Distributed Objects, as well as provide an introduction to NEXTSTEP's Database Kit. Conference Pricing & Registration The cost for the 2-day East Coast NEXTSTEP Developer Conference is $545 for those who register before December 3, and $595 for those who register on-site. NEXTSTEP Courses are $160 (each course) for those who register before December 3, and $200 (each course) for those who register on-site. Those interested can register by calling: 1-800-767-2336 or 508-470-3880. NeXT Computer, Inc.

I mean something where under Classes it would show top-level classes, plus classes from subprojs. I'm always forgetting where in the world this or that class is located, and ProjectBuilder _already_ knows, it just doesn't want to tell me. This actually wouldn't be too bad. Note that class names cannot conflict (ie, you can't have "MyClass" in a subproject _and_ in the main project), likewise with interfaces and images and most everything else. So, that wouldn't be a problem. Still and all, it would probably be nice if it did like Windows menus and had stuff like "MyApp - ./" and "MyAgent - MySubproj/" so that you could easily tell which subproject these beasties belong in. Hmm, while we're here ... how in _heck_ do you get PB to add, for instance, a French version of a .nib. From what I can see, there's nothing I can do that makes projects build correctly with other .lproj directories. [Well, coding extra Makefile.* targets certainly does it, but I could already have _that_ fun under NS2.1. I expect that PB would know these things for me, don't you think?

Hullot is actually using an IBEditor to do this with the "built-in" classes? Think of what this entails. An IBEditor is a panel.

Date: Fri, 17 Sep 1993 03:01:42 GMT Well, after deciding that the "minimum" specs for a development machine were probably out to lunch (NeXT reccommends 24 Mb RAM, 330 Mb hard disk) I went ahead and put a minimal NEXTSTEP installation and development system onto an NEC Ultralite Versa with a 180 Mb disk and 12 Mb of RAM. The results: 1. It works, with ~45 Mb to spare on the disk. (No docs were installed.) 2. The screen is small, but usable. 3. It's a lot slower. A 70-class app that took 10 min. to compile and 1 minute to link on my 040 Cube (28 Mb RAM, 660 HD) took 23 min. to compile and 2 1/2 min. to link on the Versa. 4. It Just Works, otherwise. Conclusions: If you REALLY want portability, go for it, but it's not going to be as productive as working at your desk. -Anthony

I have been experimenting with the Subprocess class provided in the Examples directory (/NextDeveloper/Examples/UNIX/Subprocess/Subprocess.m). This class performs an vfork with execl to control a child process. I call it with id subprocess = [[Subprocess alloc] init: "/bin/cat"]; [subprocess send: "hello, world"]; [subprocess send: "goodbye, world"]; [subprocess free]; intending that a shell will be forked and fork /bin/cat, which will then copy the two text lines to stdout. (This is an appkit app, so messages should appear on the console or gdb window.) Instead I occasionally get nothing, but usually get the following on stdout The old exception port is 0x1 Can anyone explain what this means? and what I need to get the cat to work? I do get a csh and a cat process created...they show up with "ps -ax". They don't seem to go away though, when I free the subprocess. (I modified it to do a [self terminate: self] when freeing to kill the child process.)

There are some good examples in the mach docs. The first chapter which explains the concepts is essential to understanding what is going on. This "signal" is actually a message sent to the thread's kernel port. The kernel recieves the message and modifies the state of the thread. The process they outline (use thread_syspend/abort/set_state/resume call sequence) actually changes the HARDWARE REGISTERS causing excecution to jump to your signal handler. They are assuming you change all of the stack info and whatnot for the executing program. The mach docs Next has published are only slightly modified and reformatted versions of the docs which were written by the folks at CMU who wrote mach and were aiming their discussions at people who would use the mach microkernel to write their own OS on top of it, like they did with BSD. That is why the example is so obtuse. It is relatively easy to send messages between threads using normal mach messages and ports. This can also be accomplished with distributed objects. In either case I recommend familiarizing yourself with the basic concepts of mach so you know the limitations of each approach. For me making a diagram of the concepts helped dramatically.

I just "dragged" the sybase variable into the field to make the connection. What happens when the app is run, of course, is that the fields which were set to "" (empty string) show up as "Jan 1 1900", the sybase default. I also noticed that if the datestring value is uninitialized (ie NULL) that the field just remains blank, which is how I would like it. However, I don't wish to embed "NULL"s in all the datestrings throughout the system. So, my question is, is there any way to have these values show up blank in the textfield as opposed to the "Jan 1 1900" value?

The NeXTSTEP 3.1 compiler is documented as being a NeXT-modified version of the 2.2.2 release of the GNU compiler. So I downloaded libg++-2.2.tar.gz from cb-iris.stanford.edu. I unbundled the distribution and ran './configure next' which said that it couldn't find gcc which was not surprising since NeXT calls their compiler cc. So I made a link from /bin/cc to /usr/local/bin/gcc and reran './configure next' which appeared to have no more problems. I then ran 'make all' which worked well for a while until I got the following error message: gcc -g -nostdinc++ -I. -I.. -I. -I./../src -I./../g++-include -c procbuf.C procbuf.C: In method `int procbuf::sys_close ()': procbuf.C:91: incompatible pointer types for argument 0 of `int wait (union wait*)' *** Exit 1 Stop. *** Exit 1 Stop. *** Exit 1 Stop.

I dug a little deeper and seemed to determine it was actually the Workspace that has the problem. If you launch the program manually (from the command-line) it typically will run. If you log out and log back in, typically the workspace will launch it. If you can get more details about the scenario, please post. It's more of an annoyance than a problem.

I assume the exception port has something to do with communication between gdb and the target app. Running without gdb seems to work fine. Unfortunately this makes for awkward development, since gdb affects the behavior of the app, but I can get around that for now by developing with a fake Subprocess class.

I need a class to receive a message called "saveTextFile". For some reason, the message is not being called through the first responder chain. The program is a slightly modified version of TextEditor tutorial that came with the developers kit. This program contains two nib files. One nib was created for the main application menu, and another is created for the document class. Every time a new document is created, a new instance of the document nib is loaded and a new instance of the document class is created. In the document class, there is a method called "saveTextFile" which I want called from the menu panel. I parsed the class to make the method "saveTextFile" visible to IB. I connected the "save" menu panel to the First Responder at the action "saveTextFile". In the document.nib I created an action called "saveTextFile". I did a make clean and then a build to ensure that everthing got recompiled. Unfortunately, the menu panel generates the message, but the method in the document class "saveTextFile" never gets called. This is the code that gets called to create a new document.nib and class. - createDocument:sender { newDocument = [[Document alloc] init]; [newDocument show:self]; return self; } Since I have two First Responders, I put "saveTextFile" action entries into both First Responders (one for the main application nib TextEditor.nib and one for the dynamically loaded nib document.nib). I'm totally stumped. Does anyone have suggestions?

This unfortunately is not any of the "legitimate" return codes for this function so I have no information to go on when trying to figure out what is wrong. 2nd Approach: Write a loadable kernel server and use the function call unsigned char * data = (unsigned char *)map_addr(0xA00000, 4); When I use this function call I get an error when I try to install the loadable kernel server from rld saying that map_addr is undefined. This is very surprising since map_addr is specifically listed as a loadable kernel server function. Any information on what I might be doing wrong with either of these two approaches, or suggestions for alternative methods of solving this problem would be greatly appreciated. Recently I've found myself longing for the "good-old-days" of DOS where you'd just load a segment register and an offset register and go.

Thanks. This is a "feature" of the cthreads package. It caches the threads for reuse at a later date. If you fork 15 threads which then exit, then fork 15 more - you will still have 15 threads as the second set reuse the 15 ones from the first forks. This is ok if you're constantly reusing some small range of threads, because it doesn't have to keep recreating them from scratch, but really sucks in general. The cthreads package lacks, and unfortunately getting around it's deficiencies is non-trivial and would be better done with writing a replacement.

Thanks. > The cthreads package is actually a thread manager. So when you call cthread_fork(), it first goes to see if it has an available thread in its thread pool and, if not, it then calls Mach with a thread_create() to get mach to allocate it a thread. When a "c" thread terminates (either implicity or by cthread_exit()) the cthreads package puts the thread asleep and retains it in its thread pool for later allocation (by chread_fork()). This done for performance reasons, since you do not have to incur the overhead of setting up a thread in the kernel. Eugene D.

The color screen is the main screen, which is to the right of the mono screen. I'm trying to make an app remember which screen its main menu was on the last time it was terminated. I get a variety of misbehaviors that I don't understand. Approach #1 in appDidInit: (use current menu location) iScreen = atoi(NXGetDefaultValue([NXApp appName],"Screen"));// put in DDB by me [NXApp getScreens:&pvsScreen count:&nScreen]; [[NXApp mainMenu] getFrame:&sRect]; [[NXApp mainMenu] moveTo:sRect.origin.x :sRect.origin.y screen:&pvsScreen[iScreen]]; after suitable rangechecking on iScreen, of course. The result is almost right. When the program is launched, its main menu is on the correct screen, but if it is on the mono screen, its location is right-shifted by an amount that seems to depend on the menu's distance from the left edge of the screen. Approach #2 in appDidInit: (use menu location in defaults) iScreen = atoi(NXGetDefaultValue([NXApp appName],"Screen"));// put in DDB by me [NXApp getScreens:&pvsScreen count:&nScreen]; pkvbLocation = NXGetDefaultValue([NXApp appName],"NXMenuLocations"); sPoint.x = atof(pkvbLocation); while (' ' != *pkvbLocation++); sPoint.y = atof(pkvbLocation); [[NXApp mainMenu] moveTo:sPoint.x :sPoint.y screen:&pvsScreen[iScreen]]; This causes the main menu to always appear on the main screen at launch, regardless of its previous location. Various kinds of fooling around with fabs and fmod on the x-value don't seem to affect it at all. For both methods, I have verified that the values being used for the screen and menu location are reasonable. Does anyone know what's going on here, and how to do it right? In this case, I think I'd be happy to hear someone say that I'm a doofus and I missed the obvious. Steve abell@netcom.com

No. The problem is that most programs look something like: if( !(cpid=fork())) { /* Do some processing like setting up stdio or terminal. */ /* Then call on a child program. */ exec*(*); } The amount of time spent on the child side of the fork() is generally so small as to make it impossible to attach and debug it before the exec* is called. In general, you want to debug that child code, and not the program it executes! [Worse, usually it's not executing the right program due to bugs in that code ...] Anyhow, I've had success with inserting a sleep() call at the top of the child code, which will give me time to attach to the child process from a different GDB. Then I can return from the sleep() call and continue where I wanted to be. There are still generally tremendous amounts of trouble involved with timeouts and the like (running the debugger on the child throws timing concerns in the parent right off the scales), but it _is_ doable, with care. Another hint is to make certain that you understand the difference between fork() and vfork() well enough to use vfork(), if that's what you're using. I've found that vfork() can get you into trouble if you don't move slowly and carefully.

It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. comp.sys.next.hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP.

Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. comp.lang.objective-c Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. comp.object Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention.

There are two different limits that apply to Mach ports. One is the maximum size of a simple message: MSG_SIZE_MAX (8192). That value can't be raised, and includes headers and type information.

Basically as far as I know, the object archiving (NXSave?) saves instances of objects. I want to be able to save a class. The longer version of the explination: Below, A is either 'program A' or 'file A'. If A refers to 'file A', then file A would be a binary file. A knows about class a. Program B does not know about class a when it is compiled, it does however know that A will give it a description of class a. The optimal solution would allow the user to be able to type in the name of (program/file) A and the name of class a at run time. If A above refers to file A, then there would have to be a program to create this file. I envision a short piece of code for which only a few lines are changed each time to create different files holding the classes (like the include line and maybe a preprocessor command). In this case, it would suffice to have Program B have the user type in just the name of the file (as I could store one class per file if nec.). If A above refers to program A, I would assume that B would be invoke it via a process. I think I would like the 'file A' solution better. I expect to have many A's sitting around and the file solution would use less space (I would think). What about speed? I have been reading the Garfinkel book. I am still (very) early in the design stage so ANY comments/suggestions would be appreciated. A list of NeXT object descriptions which I should look up in the General Reference manual to do this task would be very helpful. Thanks, Mark Stankus

Some how I can't believe > it would be that simple. DPSCreateStreamContext doesn't open up a "real" context at all, but simply shoves everything at the stream provided, possibly with some conversion (e.g., from binary encoded objects to ASCII). You probably don't need any conversion - using DPSCreateStreamContext would be superfluous. If you believe the PostScript you are going to receive from the serial port is a full print job, then the way to do it would be to make sure the stream starts with "%!" and pipe it off to an lpr process. You could, in theory, simply use DPSWritePostscript to the printer context. I'm not sure if the printing package can add DSC comments at that point. To guarantee that you get the full benefits of the printing package, you'll have to do some work. You'll need to capture the PostScript stream, splitting it up into pages, and activate the print command, having drawSelf:: draw each of the pages in turn. 99% of the PostScript out there can be split up into pages simply by scanning for "showpage", but there are some annoying exceptions. -- Scott Byer NeXTMail: byer@mv.us.adobe.com Adobe Systems Incorporated These are *my* opinions, and 1585 Charleston Road, P.O.

Could someone give me an Example ? I don't know about "AppKit correct" ways - I'd jump immediately to using "xyshow" with a number string in a wrap. Let me pull up an example... In a wrap: defineps PLWDrawPlanets(float gray, X, Y; char CharString[i]; float numstring XYCoords[j]; int i, j) gray setgray X Y moveto (CharString) XYCoords xyshow endps In C: static void drawPlanetSet(PDrawingSet set, float gray) { set->deltas[set->last++] = 0.0; set->deltas[set->last++] = 0.0; PLWDrawPlanets(gray, set->firstX, set->firstY, set->radii, set->deltas, set->which, set->which * 2); } This is done within the confines of a lockFocus on the view to be drawn into. The deltas are in a single array, organized as pairs (I have a bad habit of not using multi-demensional arrays when I could - I don't trust compilers :-). Note that this one call could draw all the text for a view. The numstring is also a *very* efficient way of getting large amounts of numerical data into the interpreter. (If you are doing a lot of "rect" operations, consider going to the numstring form of those operators. You'll have to write your own wrap, but it can be worth it.) However, note that the values for xyshow are _deltas_, not absolute coordinates. That means that if you have to edit a portion of the string, it can be tricky. But the performance gains from coalescing everything into one show are significant (up to a point - don't try and show more that about 800 characters at once, or the interpreter bumps out of the "fast" special case). Do the xyshow along with the other graphics being drawn for your view - and don't forget to set the font for the view sometime beforehand. I wouldn't go setting it everytime, unless you are unsure how it's set. -- Scott Byer NeXTMail: byer@mv.us.adobe.com Adobe Systems Incorporated These are *my* opinions, and 1585 Charleston Road, P.O.

From: aking@bbn.com (Allen King) Newsgroups: comp.sys.next.programmer Subject: DSP development on NS/FIP with JTAG Date: 21 Sep 1993 19:19:04 GMT Organization: Bolt Beranek and Newman Inc., Cambridge MA Distribution: world Message-ID: <m9ukt8INN8k4@news.bbn.com> We're planning a system containing a hand full of DPS chips (C40's or 96002's) and specialized hardware as a stand-alone system, which interfaces to a "host" for source development, operational control and graphics display. Since I've been using a Next at home for the last 18 months, I know the advantages of NextStep for developing the user interface on it, and I'd like the system I use at work to use NS/FIP. (Man, it's hard to "do X" after you've become accoustomed to NextStep.) And I think the GUI which resulted would turn some heads. However the devil lies in the details, and the GUI is not necessarily a part of the project which we want to take risks on. But if I could understand how the following would work, it might fly: 1) Source Tools: Theory says that DOS programs should "just work", given the correct DOS emulator. Is there something I have to buy that works with 3.1, and/or don't I remember that 3.2 comes with it bundled. What performance should I expect, what fraction of native DOS or windows mode? 2) Program Loading/Control: We plan to use JTAG, and I'd bet that there are custom boards for PC's that let you talk to DSP's that way. I'd also bet that their drivers do not support NS/FIP! Has anybody gotten NS/FIP to talk JTAG? If not, how long would it take to develop one? How would one go about it? What are good boards to use? How risky is it? 3) Data Exchange: We need only about 1MBit (on 4kByte blocks) and 15 feet here, and its implementation on both the DSP and NS end should be minimal. (Nothing fancy, fixed point to point.) What exists that is, or could be made to be, NS/FIP compatible. I've been thinking Async Serial, SCSII, JTAG, or ... Ideally, I'd like to put a couple of chips (or less) on the DSP board, buy an off the shelf board for the PC, and start accessing it through objects ;-) So I'm looking for approaches, pointers, experiences, sanity checks, driver consultants, bright ideas, or anything else which could help me bring this technology to my company. We plan to talk to the DSP manufacturers in the next few weeks, and info gained here will help. Thanks Allen King P.S.: Unfortunately, I am only able to read about 50% of this group, usually with some delay. Therefore I'd appreciate email responses, and I'll summarize (that is, providing my Pnews gets better). Thanks again. aking.bbn.com

I'm working on a Workspace Inspector for sound files. For ATC files, I'd like to provide a realtime spectrum analyzer. Can't get any info outa NeXT or CCRMA. Trouble is, ATC seems to extend its format as the complexity of the sound increases. For single frequency files, there appears to be two sets of ordered 10 word frequency data, possibly sin/cos transform coefficients. The remainder is variably sized, probably including phase information. For complex sound files, the blocks are larger than 10 bytes, and the obvious symmetry of the blocked the sine wave data is less evident. Has anyone figured the format out, or happen to have information they'd care to share? I hope they aren't so secretive with the NeXTime formats!

From the documentation: Maps the device memory corresponding to localMemoryRange into the calling task's address space, and returns IO_R_SUCCESS. If you are making this call as the result of a get/set parameter invocation, you'll be in the wrong thread. Making this call from initFromDeviceDescription is a safe place to do it. Joe Pasqua

It works fine, except a problem that blocks the entire development. Each time the driver receives a block of data from the hardware, it must sends a message to a port that belongs to a user application. The message is received except if the body contains out-of-line data. In this case, the msg_send function returns the code Invalid Memory. The message is built by hand, so we could miss something in the initialisation, but the same code works between to task at user level. The block of data to be sent is created using the vm_allocate function (with the value of kern_serv_kernel_task_port() as the first parameter). It is possible to read and write the allocated memory but not to pass it through the mach messaging system. The documentation says that it is better to use the msg_send_from_kernel function, instead of msg_send. Unfortunately, there is no prototype for this function anywhere. The function is in the library and the driver can be loaded, but when it tries to call the function, it plants the system. Has anybody an experience to share ? Did I miss something ? Thanks, Michel. -- ---------------------------------------------------- E-Mail: michel@unomain.teaser.com -----------------------------NeXT Mail-Welcome------

The files are just .o files from the compiler. You can also group them into a combined .o too. objc_loadModules is a little quirky, in that it "stacks" classes into your app, and to remove them you "unstack" them. That makes it tricky to unload classes that you don't want without removing some you do. Usually, though, you don't unload classes anyway. This is easier if you just create bundle projects and use the NXBundle class. This class provides methods for loading the classes in the bundle. --- NeXTMail:Peter_Kron@corona.com Corona Design, Inc.

If I have a directory like ~/MyApps in my ApplicationPaths default, the Workspace finds the occurrence of Kor.app in ~/MyApps, and also appears to descend into subdirectories like ~/MyApps/Proto looking for applications. Not only that, the version of the app found in ~/MyApps/Proto is given first dibs on files double-clicked from the Workspace. (For example, select a file in the workspace like barf.tiff, hit command-3 to see an ordered list of apps that can open this file). I was surprised that apps in SUBDIRECTORIES of the directories listed in my ApplicationPaths were registered by the workspace. Is there any way to subvert this feature?

Once upon a time... NeXT was considering (pursuing?) obtaining patents on ATC. As you're no doubt aware, the principal inventor is also affiliated with CCRMA. I don't know what the status of the patent application is, but any type of public disclosure would essentially place the invention into the public domain and effectively invalidate the patent application. It would also not be unreasonable to expect to see similar measures taken to protect NeXTime formats. Sorry dude. Welcome to the "real world" (repleat with all it's legalities). Of course, there is a silver lining.

Here at NeXT we basically work on one language, then send out the English.lproj to someone to do the translation. We aren't doing hard core work in all of our languages at the same time. What's more important than adding support to PB is enabling tools to point out differences in resources, so that the translators can know what's changed from the last time they translated the nibs. Also so that the translations can be checked for accuracy. By the way, the above mechanism allows you to go to the Attributes mode and change your main language so that you can work on the alternate languages. Remember to change it back so that all the languages get installed. This is an area we could make better. There are some other small changes we could make to enable better multi-language development. But I don't think we want to go overboard. Most apps are not multi-language, and we need to support all our customers. Dave Moore

I realize > that NeXT wants transparency and all, but I just don't grasp a > great deal of difference between 8 bits of grey, and 8 bits of > color (esp. not on a color graphics adaptor...) Well, the big reason is alpha channel. Remember how these systems do color. 8 bit color (a.k.a. "toy color") is done using a color lookup table. When used for doing 8 bit gray, pixel values == gray level, and alpha calculations become easy - no inverse loopkup needed. (dest = src1 * alpha + src2 or somesuch.) For 8 bit color, a pixel's value isn't particularly useful - what is needed is the RGB values, which requires a reverse lookup through the color table. Then the math has to be done (the same amount of math as on a 24 bit color system - 3 times as much as for grayscale), and then a forward lookup must be done. You can hardwire a reasonable color table to make the forward lookup easy (using a 2-4-2 scheme), but "easy" means you still have to mask and shift and or the components back together. And you can either take the performance hit for both sources, or eat up a ton of memory with 32-bit deep retained window buffers. (dest = (red & 0xc0) | ((green & 0x70) >> 2) | ((blue & 0xc0) >> 6), and each component looks like red = clut[src1].red * alpha + clut[src2].red - not pretty, eh?) What this adds up to is poor performance for 8 bit color whenever alpha channel is involved. Mind you, most workstations only come with toy color, so if NeXT is serious about being multi-platform (and I believe they are) they will have to do 8-bit color sometime. They will most definitely want to make it a configuration option, however, so that the impatient among us can hop back to 8-bit gray. Or, another option is to drop to 1-bit alpha (or threshold the 8-bit alpha at 127), losing the transparency effect - this would be acceptable for window moving operations and scrolling, but fancy icon effects and such would be lost. -- Scott Byer NeXTMail: byer@mv.us.adobe.com Adobe Systems Incorporated These are *my* opinions, and 1585 Charleston Road, P.O.

I assume you mean you wish to load classes into a running program, as opposed to a bunch of objects that were archived to disk. objc_loadModules loads a .o file that has the classes in it, like that created by the compiler.

As I understand it (correct me everybody if I'm off): 8-bit color requires the use (on most systems) of a Color Look-Up Table. This is basically a palette chosen by an application from a large number of colors (i.e., you can choose from millions of colors, but only have 256 at a time). PostScript does not support CLUTs because they are, well, nasty hacks which were created in the past when full color was still a twinkle in ol' Bill Gates' eye. PostScript's model basically says that programs can ask for any color they want, and PostScript will try to accomodate them. A lookup table would deny colors to some programs when giving colors to others. A program could change all the colors on your screen, a common occurence in X and on the Mac. 8-bit grayscale gets around this because PostScript *does* allow a system to be written that doesn't use color at all (hence, the original 2-bit NeXTstep). Programs ask for a gray level, and PostScript rounds that off to the nearest gray level in its 256 standard grays. It's much easier for PostScript to implement and still provide a non-lookup-table "look" to programs. However, PostScript is *still* using a lookup table for the grayscale--it's required by 8-bit hardware. But it just handles the lookup table itself and presents an "any gray you want" interface to programs. What I wish NeXT did was supply a map like so: 2-bit red 2-bit blue 3-bit green (more discernable to the eye) 1-bit alpha (0=opaque, 1=semitransparent) Total: 128 colors across the spectrum Or: 2-bit red 2-bit blue 2-bit green 2-bit alpha (opaque through transparent) Total: 64 colors across the spectrum Or: 2-bit red 2-bit blue 2-bit green 2-bit gray flags Total: 64 colors across the spectrum, 128+64 grays. Perhaps, though, there are hardware bitwise problems with such schemes. __________________________________________________________________ Sean Luke MILK: It Comes From Cows Brigham Young University sean@digaudio.byu.edu NeXTmail now welcome :-) __________________________________________________________________

From the 3.0 Release Notes included with version 3.1 of NS/Intel: "The Release 3.0 Objective-C++ compiler is based on version 1.39.1 of the GNU Compiler which directly supports version 2.0 of the C++ language, as specified by AT&T (the Release 2.0 compiler was based on version 1.36.4 of G++). The GNU compiler has been extended to recognize Objective-C constructs within C++ source files." And then from the 3.1 Release Notes included in the same release: "The Release 3.1 Objective C compiler (as well as the Objective C++ compiler) is based on version 2.2.2 of the GNU Compiler (the Release 3.0 compiler was based on version 1.93). NeXT's implementation of Objective C has been integrated into the version 2.2.2 GNU sources." I suppose anything in the 3.1 release notes supercedes anything in the 3.0 release notes. SInce I'm not familiar with GNU you'll have to draw your own conclusions. libg++ is not included, although I believe an unsupported version can be obtained (ftp.next.com?).

Most apps are not multi-language, and we need to >support all our customers. I checked out the mechanism that Dave describes, and it does work. You can have, for example, an English.lproj and a French.lproj, and if you change the language field in the attributes inspector the focus of the files browser changes to the appropriate lproj directory for all localized resources. This would allow someone to work on any language's files directly from PB. Since I generally put away my FileViewer once I open a project, because I can do most of the file manipulation I need while I'm working on a project right from PB, the ability to change languages to access the other language files without having to go back to a FileViewer is quite nice. Beware, however, that if you do not create a French.lproj in FileViewer, and change the language field to French from English, English.lproj gets renamed by PB to French.lproj. Once both directories exist this no longer happens. Setting the project's language to English and adding French.lproj to the Other Resources section of the files browser gets French.lproj copied to the product (app, bundle, or palette) wrapper. Adding English.lproj to Other Resources as well causes that directory to be copied into the wrapper. This means that the files in English.lproj get copied twice, because the makefiles create the PrimaryLanguage.lproj directory in the wrapper and then copy the files inside it. If English.lproj appears in Other Resources, then it gets copied again, this time as a resource. This is inefficient, because the whole directory gets copied, not just the files inside that have changed. Perhaps PB could define a list of languages, which it then writes to Makefile as a macro (like it does now for a single language in the LANGUAGE macro). Then the makefiles could copy a .lproj directory, if one exists, for every language listed in the macro definition. Then it wouldn't be necessary to include the alternate .lproj directories in Other Resources (which feels kind of kludgey). Listing the supported languages and changing the language focus of the current project in the attributes inspector would be the only place where PB would have to deal with languages at all. This removes the special treatment that the "primary" language gets, and makes support of any language the same as support for English, or whatever the product's primary language is. PB itself then doesn't deal with internationalization except to allow more than one language to be specified. In addition, I've spent a lot of time looking at the makefiles, and IMHO copying .lproj directories from a list of languages in a macro is a relatively simple change. Since users can prioritize their languages in Preferences.app, there is no need for a "primary" language for any product, because a match between the lproj directories and the user's language preferences can be made (I believe this is what happens when an app is launched - if I've set French as my primary language the app will use French.lproj if there is one). Thus all languages are on equal footing. The only problem could be that a user's machine doesn't support _any_ of the languages that the product does (for example if not all the languages that NEXTSTEP supports were installed when NEXTSTEP was installed - they're selectable at installation), in which case a product-specified "default" language may be needed so the product can access the resources it needs to run at all. This default language doesn't have to be English, though. Dave is right that PB should not be too heavily involved in internationalization. What I have suggested seems to me to provide as much multi-language support as is necessary in PB, yet does not introduce major changes. Thoughts?

Color tables *are* a sick hack, but... Display PostScript handles color tables just fine. It's very flexible in the way you can set the color table up. Under NEXTSTEP, where Display PostScript does all of the rendering, it makes sense to use the whole color table in a color cube configuration. Using a 8 x 8 x 4 cube (3 bits red, green, 2 blue) would be easy. Or any other color cube configuration you want.

In that context, the question of reasonable internationalization mechanisms surfaced. (Summary end.) While the current method works fine on finished projects, it has its flaws on updates. Now, each nib has to be completely retranslated. I think that it could be made somewhat easyer by making IB use "International nib's". This construction would be using string tables to determine the text to be shown. To make this structure updateable, strings (or whatever) would get their number, an optional comment and some default text. Translators can then add translations in quite the same way the NXLocalizedString - tables work. Once an update comes along, the new and old string table files are diff'd: identical numbers are expected to refer to identical meanings. This latter assumption poses some problems: when does a text change its meaning or just its appeareance? Some discipline on the side of the "original developer" would be required, too: Simply changing a label and attaching new semantics to it would confuse the mechanism. The advantage would be an automated way to determine changes in the user interface. Images and sounds can be covered through their file names. One Question remains: do the layout mechanisms account for changes in the reading direction? I can imagine hardly any other case in which REAL changes to the UI happen in translation.

It isn't a matter of "can't", it's more a matter of "doesn't". Since 2.0, NeXTSTEP has supported 2-bit gray, 8-bit gray (it was there all the way back in 2.0! Just no hardware to take advantage of it), 12-bit color and 24-bit color. That means special-purpose code for high-speed compositing from one depth to another, including dithering et al. Adding 8-bit color would make things twice as complicated (conversions from and to each of the other supported depths), but wouldn't be impossible. There WOULD be the question of alpha support, however. How many bits do you use for alpha? 2? 3? 8? The first two options make more sense but give you a color word size of 10 or 11 bits. Ugh. I'd bet on the latter, despite the fact that it is a ton more resolution than required. > What I wish NeXT did was supply a map like so: > 2-bit red > 2-bit blue > 3-bit green (more discernable to the eye) > 1-bit alpha (0=opaque, 1=semitransparent) No, no, no. You're missing the point. 8-bit color would be used because that's what many PC framebuffers like to do. Alpha values have NEVER been stored in the framebuffer (well, except for video overlay on the NeXTdimension). We're more likely to see: 3-bit red 3-bit green 2-bit blue ... as is used on SGI's 8-bit systems.

The string returned was correct: "ESC-[-m". Then, when the program terminated (running under gdb), it exited with an error code (012 _without_ explicitly calling 'free( area)' and 0360 when I attempted to 'free( area)' myself before exiting.)

The FPSP routines are the same as the ones NeXT supplies in the kernel, but offer a speed improvement because the overhead of trapping into the kernel, decoding the instruction, and returning from the kernel is avoided. I have some little test programs which show that the library routines are between 1.4 and 2.5 times faster than having to trap into the kernel. Is anyone else interested in this?

I had to work around a bunch of assembler bugs, the worst being that instructions like fcmps #0x3FF80000,fp0 would not assemble properly. You can find all the places I had to do this by doing a grep '|||' *.s The original instruction is included as a comment on each of these lines so you can see what should be there. I *hope* I got all the translations correct. Use this software at your own risk!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! The file NeXTglue.s contains the `glue' routines which provide C entry points to the functions. I threw these glue routines together pretty quickly. If someone else takes the time to redo them correctly please send the improved routinse back to me. Installation should be pretty simple. Just type `make install' and wait till everything finishes. To use the routines with your programs, just add a `-lFPSP.a' to the appropriate spots in your makefiles. If you are using some routines from the `-lm' library as well, make sure you put the `-lFPSP.a' *before* the `-lm'. There is a little timing/test program in the `test' directory. The original source from the Motorola BBS is in the `arch' directory. The timing program reveals that it is still spending significant amounts of time in the kernel.

We are seeking individuals and companies to evaluate the preliminary release. An engineering automation shell is a combination of CAD, spreadsheet, and expert system. Like a CAD system, you create geometry interactively. Like a spreadsheet, you can use formulas to relate any item to any other item. Like an expert system shell, you use it to create a system that automates a set of expert design rules. Unlike a CAD system, the result is not a flat database of geometric primitives, but a hierarchical, object-oriented, language-based description which captures design relationships in a way that can be reviewed, altered, or expanded at a later date. Unlike a spreadsheet, the objects related by formulas are not structured cells, but are named "slots" within model entities. Unlike an expert system shell, evaluation is not "fuzzy", but is efficient, directed, and demand driven. The product is called "Defigner(tm)" (silent g). It is targeted at mechanical engineers and designers. It could also be used for any modeling task that is complicated enough to make change of the model a hassle. The following description was recently posted to alt.cad.autocad: "Defigner allows engineers and programmers to define any relationship between any object and control how that relationship is used. Not only can you do simple things like move something while maintaining its relationships (like moving an arc and having lines tangent to it be updated as well), but you can incorporate all kinds of engineering that performs analyses and builds the design based upon the results. One of our examples is how a lightening hole conditionally appears depending on whether there is strength enough for it or not. Using Defigner, you create geometry interactively, just like you do in AutoCAD or other CAD systems. The entities are related to each other automatically, according to how you create them. As you want the objects to have more complex/specific/controlled relationships, (i.e., more "knowledge",) you can add formulas to specify any aspect of the definition of the geometry. Formulas can be as simple or as complex as you need them to be, ranging from simple numeric constants and arithmetic expressions, to IF statements, to user-supplied C code. The use of formulas is seamlessly and naturally integrated into Defigner, much like spreadsheets like Excel and 1-2-3. Formulas can be used to define non-geometric attributes as well, such as costs and material properties. Any attribute, whether geometric or not, can use the value of any other attribute. More advanced features: Defigner automatically creates an assembly hierarchy as you use it. Defigner lets you combine sets of formulas in an object-oriented style. Various windows let you examine formulas and values. A debugger helps you find mistakes. Full undo and redo capability means you can explore possibilities without fear of breaking something. The current version only interacts with AutoCAD via DXF files. We are exploring the interest in a version that is tied into ADS and uses AutoCAD more directly. One of the issues is whether customers interested in such an advanced product are willing to put up with the limitations of AutoCAD's database." The preliminary version available now runs on NeXTSTEP 3.1 and uses the NeXT-supplied 3Dkit exclusively. The real product will use real geometric modeling subsystems which are not (and may never be) available under NeXTSTEP. The range of available geometry in the preliminary version is limited. However, Defigner is a very open system which allows users to add new capabilities or override existing ones to solve a problem. We seek people who would be interested in trying out the product and giving us that essential feedback that makes a great application. You will be required to sign a non-disclosure agreement. Previous CAD and geometric modeling experience would be a plus. If you would like to apply to be a tester, send email to info@LoftTech.com. --J Gregory

NEVER attempt to define (or undefine) conditionals such as __STDC__, __GNUC__, __cplusplus, __STRICT_BSD__, __STRICT_ANSI__, _NEXT_SOURCE, or _POSIX_SOURCE yourself. These reflect properties of the compiler and/or selected compiler options. Altering them directly may cause your executables to behave unexpectedly at runtime, and will almost certainly cause problems when attempting to recompile your sources under future NeXT Software Releases. The only legitimate way to compile with POSIX semantics is to use cc -posix* (e.g. -posix or -posixstrict); however, this is not supported under NS 3.1, and while applications can be compiled this way for verification purposes, they can neither be linked nor executed successfully. -=EPS=-

The NeXT ceases login procedures before launching the WorkSpace Manager I think. The logo NeXT icon in the upper right has the three dots, I assume because whatever it is hasn't launched. At this point I typed command command ~ and tried several things one of which was gdb. It gave me: dbg_panic: debugger screw-up I tried msg to dump msg buffer to screen and the system didnt return anything but two blank lines. Typing command command ~ returned me to the Mini-Monitor. As I think about events leading up to this I tried to compile a C program; iwf.c using the command cc at the shell. It told me I needed a header table.h in the sys folder. I moved one there, tried again, and was greeted by more, but different error messages error messages. I have since replaced all the files to their original directories, rebooted, but the results are the same. I've been through as many directorys as I can think to go through, complarin the contents on the HD with those on the OD, they seem to be the same. At least that is there are no files missing, though there are extras on the HD. I'm assuming at this point that by attempting to compile a program (originally writen for NeXTStep 2.x I later learned) that I inadvertantly altered the contents of a vital file somewhere. Oh yeah, one other thing. We hooked th cube up temporarily to the internet using a connection at my university. We changed the IP address, and while it was on the net, as a matter of curiosity, we (the sysadmin and I) telnetted a connection to the cube. I logged in to the NeXT from a terminal as /seth/ (my account) and it seemed to work allright, though of couse not with any graphic interface, just a command prompt. If aanyone out there has had a problem anything like this one, can you tell me waht in the world i did wrong? I'm fairly ne to unix, and som even the most basic things are probably escaping me.

NeXT Kernel Flags (black h/w) ----------------------------- Here's a list of some of the kernel flags. Some are commands invoked from the NMI monitor (e.g. "halt"), others modify kernel parameters (e.g. "nbuf") and the rest I have no clue about. If anybody finds out what these others do then let me know. Flag Abbrev. Description ---------------------------------------------------------------------------- astune_rate a ? big b Enlarge NMI monitor window breakpoint br ? continue c Exit NMI monitor and resume execution cache ca ? dspicr d ? debug de Start debug mode (extended kernel messages) gdb g Start GNU debugger help h,"?" Print list of NMI commands halt ha Clean shutdown and go to ROM monitor init i ? kdb_ipaddr k ? monitor m Dirty shutdown and go to ROM monitor (try halt first) mem me ? msg ms Display kernel message buffer nbuf n Number of kernel buffers od_frmr o ? phz p ? pagesize pa ? reboot r Clean shutdown and reboot rootdir ro ? stay s Make NMI window stay on screen after continuing sb sb ? scc_buffer sc ? I'm sure my list is incomplete (I found it by trial and error while looking for something else) but there doesn't appear to be a list of kernel flags anywhere in the online documentation. From "Loadble Kernel Servers, Appendix B: The ROM Monitor and NMI Monitor" (NeXT's spelling mistake, not mine :-) > NMI Mini-Monitor Commands > > The following NMI mini-monitor commands aren't currently useful for > developers outside of NeXT. > > Set or Examine Any Kernel Flag > > The command > > flag=[value] > > lets you examine or modify internal system flags (most internal system > flags are of interest only to system developers at NeXT). > > Example: > > nmi> debug= > kernel flags debug = 0x0 The debug flag has the value 0. > nmi> debug=2 > kernel flag = 0x2 Change the value of the debug flag to 2. > > Set the IP Address > > The command > > kd_ipaddr=value > > lets you set the IP address used by the computer for kernel debugging. > It's useful only to system developers at NeXT. The "nbuf" Flag --------------- The "nbuf" flag sets the number of buffers used by the kernel. Some people have found that increasing/decreasing this value improves system performance. If anybody determines the optimal number of buffers for a particular memory size, processor speed, etc, then let me know. Buffers use up memory space and increasing the number of buffers decreases the available memory (this info is displayed early in the boot process). If nbuf is less than or equal to 96 then each buffer uses 8K. For example, 32 buffers = 0.25MB, 64 buffers = 0.5MB, 96 buffers = 0.75MB. If nbuf is greater than 96 then the additional buffers use up less memory, to a maximum of 0.79MB. For example, 128 buffers = 0.79MB. Any kernel flag can be made a default boot parameter in the ROM monitor using the "p" command. For example, to change the number of buffers to 64, go to the ROM monitor and type: > Next> p > boot command: sd? sd- n=64 > ... When you next boot up, nbuf is automatically set to 64. Alternatively, you can boot up immediately from the ROM monitor with a different nbuf value by typing: > Next> bsd- n=128 Note: The "nbuf" flag can be abbreviated to "n". Therefore, more buffers can be assigned without going over the 12 character limit on the boot command. ------------------------------------------------------------------------------- This info was collected on an 25MHz '040 mono cube w/ 16MB running NEXTSTEP 3.1. The ROM version is 2.5 v66 (if it matters). Gareth Bestor (bestor@cs.wisc.edu) 09/25/93 -------------------------------------------------------------------------------

I am trying to make a font inspector for a non-Text object. (I have some Postscript code that writes in different fonts.) I have been able to cobble together a system that works almost as well as I would like, but I want to know the "official" way. The main idea is to use a Text object to display the currently chosen font which the user can manipulate with the Font Panel. When the font changes, my Text delegate gets a textWillConvert:fromFont:toFont: message from the Text and is thereby notified of the change in font. The main problem is that I can't get a Text object in IB: - TextField is the wrong class (I even tried it). - A ScrollView (which includes both the Text and scrollbar) works okay, but isn't exactly what I had in mind. - A custom View made to be a Text class works, badly. I get the delegate messages, but the View never erases and redraws itself. I think there is a problem with the initialization of the text object. Do I need a FontChangerText (subclass of Text) so I can perform my own initialization on the Text? If so, what initialization? All I really need is a custom Responder (first responder) to get the changeFont: messages. But then I also want to be able to display the font to the user, so it seems like I need a custom Text or TextField object so I can display the font. Has anyone any suggestions, examples, or words of wisdom:-? Joseph

From: eric@skatter.USask.Ca (Eric Norum) Newsgroups: comp.sys.next.programmer Subject: Updated version of FPSP library Date: 27 Sep 1993 16:34:45 GMT Organization: University of Saskatchewan, Saskatoon, Canada Distribution: world Message-ID: <2874n5$rek@tribune.usask.ca> A number of people reported conflicts between the NeXT shared-library floating point support routines and the M68040FPSP routines. I have made a patch to the `glue' routines that should get around this problem. I have also added entry points for a few more routines (sincos, etc). I would like to extend my thanks to the people that took the time to try out these routines and mail me their experiences. Here is the README for the new distribution. I will try to put the new version on cs.orst.edu this evening (Monday, September 27): /pub/next/submissions/libFPSP_p1.tar.gz ============================================================================= Motorola M68040FPSP library routines for NeXT 68040 machines. Patch level 1. Installation ============ 1. Create a new directory, `cd' to it. 2. Uncompress and `un-tar' the source files. You should than have: In the current directory: a Makefile, a README, and a bunch of assembler source files. In the arch subdirectory: The original source from the Motorola BBS. In the test subdirectory: A program to test the library routines. 3. Type `make install' to assemble the routines, create the library, and install the library in /usr/local/lib/libFPSP.a. The FPSP library is now ready to use. To use the routines with your programs, just add a `-lFPSP' to the appropriate spots in your makefiles. Comments ======== A number of people who have tried these routines have sent me mail about the libjv package also available on the archives. Yes, that package *is* faster than the M68040FPSP routines, but the speed comes at the cost of reduced accuracy. Caveats ======= These are the Motorola FPSP library routines translated to `gas' syntax. I had to work around a bunch of assembler bugs, the worst being that instructions like fcmps #0x3FF80000,fp0 would not assemble properly. You can find all the places I had to do this by doing a grep '|||' *.s The original instruction is included as a comment on each of these lines so you can see what should be there. I *hope* I got all the translations correct. Use this software at your own risk!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I was unable to figure out how to make the assembler generate a floating-point-condition-branch instruction with a word offset. The assembler insists on emitting a long offset even when the target is only a few instructions away. This makes the routines run slower, and take up more space, than they otherwise would. The file NeXTglue.s contains the `glue' routines which provide C entry points to the functions. I threw these glue routines together pretty quickly. If someone else takes the time to redo them correctly please send the improved routinse back to me. I had to put in some `magic' declarations to keep the loader from trying to pull in the floating point support routines from /lib/libsys_s.a -- again I hope I got this right. -- Eric Norum eric@skatter.usask.ca Saskatchewan Accelerator Laboratory University of Saskatchewan Saskatoon, Canada.

Message-ID: <1993Sep27.180044.9395@instep.wimsey.bc.ca> Sender: brad@instep.wimsey.bc.ca (Bradley Head) Organization: InStep Mobile Communications Inc. Date: Mon, 27 Sep 1993 18:00:44 GMT We have a problem in which it appears that an Object's zone method intermittently returns an invalid pointer. It is hard to get a handle on because the problem occurs inside of Next's distributed object code. We are working in a multi-threaded environment using only the default zone (the zone returned by NXDefaultMallocZone()). We have specified objc_setMultithreaded(YES), and we are using thread-safe memory allocation. We disassembled [Object zone] and NXZoneFromPtr() in gdb. NXZoneFromPtr() is called from within -zone method to find the (NXZone *) zone. It seems they are not thread-safe in the way that the malloc/free functions are. (ie. they don't seem to use the nxzonemalloc mutex lock. The NXZoneFromPtr() branches to subroutine findregionnolock to do the work of getting the zone - the "nolock" portion is consistent with the nxzonemalloc routine in that once it acquires a mutex lock, it branches to subroutine nxzonemallocnolock - but NXZoneFromPtr() does NOT attempt to acquire any locks prior to branching to subroutine findregionnolock. We are speculating that NXZoneFromPtr() can examine the zone data structure while it the zone is in an inconsistent state during modification by the malloc/free functions in another thread. Two questions: Has anyone else seen similar problems with [Object zone] and/or NXZoneFromPtr() in a multi-threaded environment? What work arounds can you suggest? brad... -- Bradley Head Software Developer, InStep Mobile Communications Inc. brad@instep.wimsey.bc.ca (NeXTmail accepted) 604 872-7116 fax: 604 872-7125

It was created specifically to divert lengthy flame wars from .misc. comp.sys.next.announce Announcements of general interest to the NeXT community (new products, FTP submissions, user group meetings, commercial announcements etc.) This is a moderated newsgroup, meaning that you can't post to it directly. Submissions should be e-mailed to next-announce@digifix.com where the moderator (Scott Anguish) will screen them for suitability. comp.sys.next.bugs A place to report verifiable bugs in NeXT-supplied software. Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. comp.sys.next.hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. comp.sys.next.marketplace NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. comp.sys.next.misc For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! comp.sys.next.programmer Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. comp.sys.next.software This is a place to talk about [third party] software products that run on NEXTSTEP systems. comp.sys.next.sysadmin Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. related Newsgroups comp.soft-sys.nextstep Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. comp.lang.objective-c Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. comp.object Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original comp.sys.next no longer exists--do not attempt to post to it.)

How does your programme exit? Are you returning from main() without a value? You can't call "free(area)", because "area" doesn't point to the start of memory you allocated with malloc. Ross Ridge

Message-ID: <287ksm$442@steffi.demon.co.uk> For those of you who are purists might like to check out this. ISE's Eiffel 3 is expected during 1993. It will initially be available for most major Unix platforms, AIX and VMS. A port is underway to NextStep (both '040 and '486). Future ports are planned for Windows NT, Macintosh and OS/2. Tower Corporation's "TowerEiffel" will be available this year. The initial platform is the Sun SPARC or compatible running SunOS 4.1.X., with gcc version 2.2.2 or later, or Sun's "acc" C compiler. Future ports of TowerEiffel are planned for Solaris, AIX, IRIX, HPUX, DG/UX, NextStep, Windows NT, OS/2, VMS and various Intel-based Unix systems. (Lets just see how many of these are actually delivered) IMHO: I don't know much about the linkage issues to C with Eiffel but it had better be as easy C++ in order for this to be viable in a Unix environment.

[Good reasons why deleted.] I will disagree slightly with the venerable Mr. Scott here and say that manual definition of _NEXT_SOURCE (but not the others) can sometimes be justified. Probably the most common reason for NeXT users to do this is if they are not using NeXT's pre-processor. (For example, it appears many on the net have compiled more recent versions of the GNU C compiler, perhaps to get increased C++ support or to avoid some of the known bugs in the version shipped with 3.1.) In this case, -D_NEXT_SOURCE and -ansi should not be used together; -D_NEXT_SOURCE should not be used with any C compiler when trying to adhere closely to the ANSI standard. Of course, caution is advised. Again, I don't recommend tampering with any of the other conditionals. -ccwf "Tell me," said the Yellow Emperor.

This statement is inaccurate. If you are writing POSIX conforming code to run on any of the many POSIX 1003.1 conforming systems, the BEST way to identify that code is by putting "#define _POSIX_SOURCE 1" before any system header files are included. This ensures that POSIX conforming header files will always be included if they are available. If they are not available, this will have no effect. Since _POSIX_SOURCE is a preprocessor symbol, it can only affect the preprocessing phase of compilation. Unfortunately, NeXTSTEP 3.1 is not POSIX 1003.1 compliant, so porting POSIX conforming code to NeXTs can cause minor difficulties. However, NeXT is moving toward future POSIX compliance (3.1 is a lot closer that 3.0 was). If you would like more information about writing portable Unix programs, I highly recommend Donald Lewine's POSIX Programmer's Guide by O'Reilly and Associates. It not only explains POSIX 1003.1, it also provides lots of information about kludging non-POSIX systems to make them look conforming enough.

(gdb) To my knowledge, NeXT QUIETLY fixed this BUG (lack of mutex locking) in NEXTSTEP 3.1. We've been frustrated by this bug for several weeks now with our multithreaded server at a customer site crashing about once a day due to this 3.0 BUG. I'm appalled by the poor developer relations NeXT has when it comes to revealing bugs in their code. This bug has cost our company time and money (and an ear full of customer complaints). We made the mistake of thinking it was a bug in our code - refusing to believe our eyes when debugging the core files since it seemed to indicate a bug in NeXT's fundamental NXZoneFromPtr() function. If we'd known that the bug in NS 3.0 existed when NeXT first discovered it (or more correctly, when some unfortunate registered developer reported it), we would have saved ourselves a lot of time and money. I vote NeXT release timely development kit BUG reports to registered developers (with workarounds if possible).

Distribution: usa Date: Sun, 26 Sep 1993 09:09:20 GMT Is there anyone out there intimately familiar with the WMInspector and how the Workspace handles addresses (Filename.address) directories under NS 3.1? I would like to add a fuctionality similar to what the Workspace is able to do with addresses, but with a different filetype. Specifically, my questions relate to what the Workspace does with the Address.table file inside of my ~/Library/<filename>.address directory. These files are treated specially by WS, and there doesn't SEEM to be any documentation on how this special handling happens. I've looked into WMInspector, but that doesn't seem to do it... at least, not everything that the WS does with a .address file: 1. How does the WS parse the <filename>.table file and then display what looks like a "file" for each entry in the <filename>.table file? 2. Where does it get the icons that appear for the address and table file types... part of the addresses.bundle in WM.app...?) 3. How is the dragging mechanism from one "address" window to another one handled by WS? It appears that "special things" are going on here, and I need to hook into those (i.e.: dragging a file into, between, or out of this new file type). Any and all assistance would be greatly appreciated. I hope NeXT has documented this, or at least made it easily extensible, and I'm simply overlooking something.

I don't think you can use the #line directive to do that. The reason is that macros always expand to exactly one line. (The end-of-line backslash-line continuations don't count--that happens before the preprocessor looks at the macros.) Maybe we need a new preprocessor...

None of the posts I've never seen had any justification for why precomp's "aren't worth the trouble". As far as the performance benefits, they can be dramatic. Of course, it's somewhat data dependent. The following simple example was compiled on a 32 MB machine: #include <appkit/appkit.h> main() { } Here are the results: with precomps: 1 second without precomps: 19 seconds One could argue that I shouldn't have included appkit.h, clearly I didn't need it. You can play the game of only including the headers that you need but it gets boring after a while. I'd personally rather include all of appkit or all of dbkit or whatever and let precomp's optimize it for me.

I have no idea what this is. Perhaps it's there because the old versions of the TIFFs used to have a miniaturize icon in the upper left, and both buttons share the same TIFF but the Panel would not have the mini button - easier to just cover it up than take up more room and make two TIFFs. - Drew -- +--------------------------------+-------------------------------------------+ | Drew Davidson | "Never ask a programmer if he'll have | | Software Guy | another cup of coffee because it's | | First National Bank of Chicago | nobody's damn business how much he's | | drew@fnbc.com (NeXTmail) | already had!" - me | +--------------------------------+-------------------------------------------+

Joseph's right, but don't forget you can also use the inline keyword to get the effect of a macro without the headaches (see the compiler doc) and now a word from the code police ... Personally, I'ld recommend inline functions over macros for all but the simplest tasks. - only one arcane language to deal with - lets compiler make optimizations - lets compiler give better error diagnostics - easier to debug, or change the inline decision if the function grows - easier to be sure what the code really doees since it doesnt depend on what options were used or misused on the command line this is one of the things that worked out very well in Ada over the last ten years, where people use preprocessors for special tasks like embedded SQL, but otherwise tend to avoid them. I'm glad to see other languages adopt the idea. also the C++ books suggest using const int instead of #define for similar reasons. IMHO, the C preprocessor is a hack that often causes more problems than it solves but since we're stuck with it, we should at least try to use it in a structured way - and use real language constructs instead where possible, like: - use #import rather #include (or at least use the _H trick) - use inline functions instead of #define - use const int instead #define - use enum types instead of a list of #defines PLEASE - restrict #ifdefs in source to simple well defined tasks like conditional compilation of debugging code -- Alex Blakemore alex@cs.umd.edu NeXT mail accepted

Waaaaa! But I don't wanna do it that way-- I wanna use attach! (my shell generated gdb debugging script could be easier to use if it used attach). It seems to me it's a bug if gdb lets you set breakpoints to code that addresses that aren't valid. There are various gdb options related to dynamic loading, but I can't get any of them to do what I want. Perhaps the linker needs to embed extra information in order for gdb to know how to relocate the symbols after an `add-file'. boohoo.
From: koehrsen@offroad.chem.wisc.edu (Michael Koehrsen) Newsgroups: comp.lang.objective-c,comp.sys.next.programmer Subject: method inlining, redux Date: 29 Sep 1993 23:18:23 GMT Organization: Division of Information Technology Distribution: world Message-ID: <28d53v$chk@news.doit.wisc.edu> I followed the recent thread on objective-c method inlining with interest. As it happens, I am now casting about for a term project for a course in compiler optimization, and I thought I would modify gcc to do some method inlining and static call binding, and see how much of a performance improvement it yields. Details follow for anyone who is interested and would care to offer comments/suggestions, but I have two questions that I need to have answered before I get too deep into this project: 1) Has this already been done? I gather from the earlier thread that it hasn't, but I'd hate to discover after a few weeks of digging through gcc source code that it has been, and that I need a new project. 2) Is there publicly available objective-c benchmark code? The project is much bigger, and probably less useful, if I have to write my own benchmarks. Many thanks. Here are the details: The approach I have in mind is to attempt to predict at compile time the class of each instance variable and method local variable, and replace each message for which the receiver's class has been predicted with a static call, protected by a run-time test of whether the class prediction was correct. For example: [myObject aMessage]; will be replaced by something like if (myObject->isa == &PredictedClass) // Is this test right? aMessage(myObject); else [myObject aMessage]; where PredictedClass is the predicted class of myObject and aMessage(myObject) is shorthand for PredictedClass's implementation of aMessage, called as a function. This obviously makes an assumption about the Object implementation--namely, that the compiler knows how to get to its class pointer. This assumption looks pretty safe to me. I believe the run-time class check is sufficient to deal with the problems raised in the earlier thread, notably posing subclasses, while retaining most of the benefit of static binding. Obviously the class prediction has to be accurate enough for its benefits to offset the cost of the run-time class check. In cases where the method body was available and sufficiently small (basically, a subset of messages to self), the method body would be inlined after the class test. The class would be predicted as follows: 1) If the receiver is self, the predicted class is the class in whose implementation the method occurs. 2) If the programmer has provided static type information in the receiver's declaration, the predicted class is the programmer-specified one. 3) If the receiver is a (local|instance) variable, and it has appeared in an assignment like: myVar = [AClass factoryMethod]; in the current (method|class implementation), then the predicted class of myVar is AClass. 4) If the receiver is the return value from another method invocation, as in: [[myVar aMethod] anotherMethod]; then the predicted class will be the same as that of the inner receiver. Many methods return self, after all. 5) As a last resort, the known class hierarchy could be searched for classes that implement the method. I'm not sure what I will do in the common case where this search turns up more than one class. -- Michael Koehrsen koehrsen@whitewater.chem.wisc.edu UW-Madison

You could do this by fiddling with the back end of the compiler and the linker. Change the code generator to emit "relocation entries" for classes/methods and then change ld so that it would digest them. This could potentially reduce a message to a single instruction. You could also do this by using some sort of name mangling ala C++. (2) Cache lookups. The various run times do this already, but there is, I believe, some room from improvement, if you do this at the call site (instead of inside objc_msgSend). There are at least two variations here, depending upon where you want to cache the information. Also, it is important to allow the caches to be "flushable" (which would be required for dynamically loading classes). N.B. In both cases below, "cache" is a single entry cache. Caller side caching would look like: // [myObject aMessage]; if (myObject->isa != cache.class) { cache.method = methodLookup(myObject, SEL(aMessage)); cache.class = myObject->isa; } cache.method(myObject, SEL(aMessage), ...); Callee side caching would look like: // method invocation cache.method(&cache, myObject, SEL(aMessage), ...); // "hidden" args change!!! // then in the method prologue code if (cache->class != myClass) { cache->method = methodLookup(myObject, SEL(aMessage)); cache->class = myObject->isa; cache->method(cache, myObject, SEL(aMessage), ...); // more like a "jump" as opposed to a "call" } // Real method code begins here The advantage (I see) to the callee side caching would be potential space saving (the code "bloating" is proportional to the number of methods rather than the number of invocations). Since (in the "ideal world") a method should be invoked at least once (in order to justify it's existence), callee side caching should result in a smaller image (satisfying those who still care about such things). However, before you charge off and implement whatever it is you end up deciding to do, I *strongly* encourage you to meter some code and *measure* the types of things you're assuming (e.g. for a particular "call site", the class of the messaged object being "constant" or predictable). This way, you should be able to predict the types of performance gains (or losses) you might see when you've finished all your hard work. You should be able to readily cobble up a copy of the GNU ObjC Runtime to generate so me interesting statistics for you (then all you need is some "victim" code :-).

POSIX is not "portable UNIX." POSIX is not UNIX. It's a "wannabe" at best--a desperate attempt to retain market share for proprietary systems like VMS and MPE, and at the same time scatter buckshot throughout the UNIX community. Maybe X/Open has _some_ credibility. POSIX certainly does not, except among suits and marketroids. One of the things NeXT can do--because of the Mach base--is allow UNIX binaries and POSIX binaries to run in different Mach tasks at "full native speed." But as far as the binaries are concerned they see completely different and incompatible operating systems. Of course, this idea is hardly original--several other vendors (e.g. HP/Apollo, Pyramid, ELXSI) have offered "multiple universes" on their machines. I resent having to pay for "dead wood" features just to get bug fixes in the base product. The current "developer" product should be folded into the "user" release, and the MISfits who want their systems bloated with POSIX, OSI, X, or Win32 should be reamed accordingly. -=EPS=-

Two ideas come to mind. There tend to be quite a few methods which return some instance variable and often a bunch of methods that simply return self. There are also methods which return constant values like a selector, for example. It seems that the compiler could recognize these very simple methods and generate special "subclasses" of Methods (I am referring to struct objc_method *) which can be handled directly by objc_msgSend without actually invoking the function at all (or even generating it). For example, let's say a method simply returns self. The subclass of Method could be "SelfMethod" which, when objc_msgSend sees that it has found a SelfMethod, it simply returns the receiver (the first arg to objc-msgSend) rather than branching to the method. Another method might return a constant and nothing more (say a SELector). The compiler could generate a ConstMethod which holds the return value for that method. Then objc_msgSend could simply return that rather than branching to the function. Other Methods could be SetMethod and GetMethod which hold the offset of the instance variable to be set or gotten. Here's what might be added to objc_msgSend (in pseudocode): id objc_msgSend(id receiver, SEL aSelector, ...) { : : Method theMethod = class_getInstanceMethod(whatever); switch(theMethod->type){ case SelfMethod: return receiver; case ConstMethod: return theMethod->const_value; case GetMethod: return receiver[theMethod->offset]; case SetMethod: //framePointer[12] is the third arg to objc_msgSend receiver[theMethod->offset] = framePointer[12]; return receiver; case RegularMethod: //dispatch the function (reusing the stack frame, of course) continueExecutionIn(theMethod->IMP); } } So the question becomes, is the savings of avoiding the call to these special, very simple methods worth the additional overhead of checking the method->type for every message send? Of course it depends on the program -- if the program has lots of calls that do these extremely simple things, then the savings could be real. For example, if you disassemble a method that does nothing but return self, you'll find that there are five instructions, four of which are function call overhead. I presume similar stats for ConstMethods. Also, there is overhead in dispatching the function (reusing the stack frame takes at least four and perhaps six instructions). So for ConstMethods and SelfMethods, the overhead ratio is as much as 10:1. A quick and dirty test of my approach shows that the case statement approach takes 6 instructions (compared to 11) for the ConstMethod. The constant overhead of the case statement could be reduced via some hand optimization since the bulk of the calls are going to be regular methods. (If the number of cases is few, it appears that a case statement is not a good way to go). I would really like for the compiler to automatically generate the set/get methods for me. Since there doesn't need to be any code (ie it'll never execute) why require me to write it? Perhaps I could give the compiler a list of ivars to generate Methods for, or something like that. Caveat: All of the above comments may not apply to Gnu's runtime as I am not sure they handle objc_msgSend in the same way as NeXT. Last I heard, their objc_msgSend returned an IMP and did not do any function dispatching.

That's a joke! Has anybody installed libg++2.4 under NS3.1 using gcc 2.4.5? In NeXT's libg++2.3 the header file basically just included the appropriate next header from from /usr/include They basically looked like this (etc) extern "C" { #include <_G_config.h> #include_next <unistd.h> } Now, in libg++2.4 there are prototypes as well as the instructions necessary to import the appropriate next header files. Some of these protoypes conflict with the default next prototypes in _their_ include files.

I have a special situation in my program where a timed entry function gets called (with a priority threshold of 12) every 0.1 seconds. On a given call of this function, I would like to permanently disable an on-screen slider. This works If and only If the user has NOT mouse-downed on the slider. If the user is moving the slider, the timed entry sends the disable message, but it is "ignored" by the slider. Is there a way to over-ride the user control of the slider? I could probably figure this out myself given time, but I am 199% bogged down with my Masters Thesis and classes. Thanks, Eric

NeXT warns adamantly against it, because the Workspace is responsible for that tile [for command drop-ons, etc]. One proposed solution was: - create a faux window which always "covers" the app tile. Your fake appIcon window gets the events; you deal with the ones you want, and then pass other events to the real appIcon. Sounds really breakable. To quote someone famous in software at NeXT: I think the answer is "you just can't do it." All mouse events in the app tile are supposed to be reserved, so there's no supported way to do what you're asking for. I haven't spent too much time on it, but I can't think of any simple way which would let the app get mouseclicks. I did take a look at one app which actually puts a slider in the app tile, and it does a lot of hairy stuff to accomplish what it does, and still it has problems. And what's more I doubt it works between major releases, the way it mucks around with the private window dictionary. andrew -- ||<<->>||<<==>>||<<++>>||<<?>>||<<+>>||<<-->>||<<==>>||<<+>>|| !!

State 3 is the button inactive (and presumably unchecked). It will visibly dim in State 3 to distinguish it from State 1.

Hint: it's a popular library function. I'm going to guess that you mean printf, where format strings can have leading 0's to indicate padding with zeroes instead of spaces. If this is indeed what you meant, I have to point out that it doesn't count because the leading 0's are inside string constants (the format string) and therefore are not treated by the lexical analyzer, only by the printf (and fprintf, and scanf...) library function.

I didnt mean that macros are not sometimes very useful, and that clever people like yourself cannot come up with good uses for them. I agree you couldnt use an inline function to do the same thing you show there because a. methodPlusArgs can be completely arbitrary text b. you dont want to evaluate methodPlusArgs prior to doing the if condition. I don't dispute that there are other good uses. I'm just saying that most people rely on the preprocessor for things that can now be done by the compiler in ANSI C. The compiler usually does a better job, but most people still dont take advantage of features that have been in C (and other languages) for years. A prime example is enums. > how about when multiple objects need to implement a method (their > superclass declares it, but each subclass implements a different version)? > - myMethod > { > MY_METHOD_BEGINNING; > if (theResultsFromTheBeginning) { > // All kinds of clever stuff in here, which varies with subclasses > } > MY_METHOD_END; > } > This is much more convienient and avoids typos.

Message-ID: <CEBy30.61p@news.cis.umn.edu> Sender: news@news.cis.umn.edu (Usenet News Administration) Organization: Geometry Center, University of Minnesota Distribution: na Date: Sun, 3 Oct 1993 16:33:06 GMT I'm trying to find an easy way to maintain fat .a libraries under 3.1. We'd like to have everything in "fat" form: .o, .a, and executable files. All the tools seem to handle this nicely, except "ar" in the case where we're rebuilding (e.g. replacing a subset of .o files in) an existing fat library, where it complains ar: libjunk.a is a fat file (use libtool(1) or lipo(1) and ar(1) on it) libtool doesn't seem to do it, either. The closest I can find is libtool -o libjunk.a libjunk.a fred.o sam.o but, rather than replacing libjunk.a's fred.o with the new fred.o, it gives a ton of complaints like libtool: warning for architecture: m68k same member name (fred.o) in output file used for input files: libjunk.a(fred.o) and: fred.o (due to use of basename, truncation, blank padding or duplicate input files) libtool: same symbol defined in more than one member for architecture: m68k in: libjunk.a (table of contents will not be sorted) libtool: for architecture: m68k file: libjunk.a(fred.o) defines symbol: _CamAlignZ libtool: for architecture: m68k file: fred.o defines symbol: _CamAlignZ (and so on for all globals defined in each object file, and for each CPU type.) I'd be willing to do this in two stages: delete the library components which were about to be replaced, then use libtool to insert the new ones. But I can find no easy way to delete .o components of a fat library. Presumably I could do all this by replacing "ar" with a script which used "file" to test for fat libraries and object files used "lipo" to split the library and object files into two (or N) pools of thin files used "ar" on each set of thin files used "lipo" to reassemble them into a fat library but that's, to put it mildly, disgusting. Or, I could replace "ar" with a script which removes the old library, then simply uses ar to build a fresh one from the supply of .o's. This would be OK (and is what I'm actually doing at the moment), except that the .o files don't always live in one directory; it's nice to be able to just replace the ones being changed at the moment, and that's the way our Makefiles were written, anyway. Am I missing something? Help or sympathy appreciated! Stuart Levy, Geometry Center, University of Minnesota

It was created specifically to divert lengthy flame wars from .misc. comp.sys.next.announce Announcements of general interest to the NeXT community (new products, FTP submissions, user group meetings, commercial announcements etc.) The NEXTSTEP FAQs are posted here monthly as well. This is a moderated newsgroup, meaning that you can't post to it directly. Submissions should be e-mailed to next-announce@digifix.com where the moderator (Scott Anguish) will screen them for suitability. comp.sys.next.bugs A place to report verifiable bugs in NeXT-supplied software. Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. comp.sys.next.hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. comp.sys.next.marketplace NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. comp.sys.next.misc For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! comp.sys.next.programmer Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. The NEXTSTEP programmer FAQs are posted here. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. comp.sys.next.software This is a place to talk about [third party] software products that run on NEXTSTEP systems. comp.sys.next.sysadmin Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. related Newsgroups comp.soft-sys.nextstep Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. comp.lang.objective-c Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. comp.object Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original comp.sys.next no longer exists--do not attempt to post to it.) Exception to the crossposting restrictions: announcements of usenet RFDs or CFVs, when made by the news.announce.newgroups moderator, may be simultaneously crossposted to all c.s.n.* newsgroups.

The server is a V.6 server based around Novell Netware. It has a TCP/IP listener on port 1525 (this has been verified by other means). There is also an SPX listener on the server. I have verified both listeners by other means I set up the server to be called CURSCI, and the host name (by name lookup) is mail.cursci.co.uk.

No, it's a feature. You just requested "Octal Value 8". Since the octal numbering system contains digits between 0 and 7, the compiler pointed out your error. If you take out the 0 then you're requesting "Decimal Value 8" which is a valid digit. - darcy -- "No man should be discouraged from entering business through fear of taxation." -- N.

As for your problem: yes, you are doing something wrong, and no, the question is not the least bit NeXT-specific--all UNIX machines will exhibit similar behavior. The problem is that you're not waiting for child processes. When a process dies, it enters a "zombie" state--nearly all of its resources are freed, but its process slot is still occupied until its parent does a wait()/wait3()/wait4() for it--or its parent dies, in which case the processes become orphaned, and init gets to clean up after them. In your case, the best thing to do is probably a traditional [synchronous] wait, e.g. while (((pid=wait((union wait *)NULL))<0&&errno==EINTR)||pid!=child); if (pid<0) perror("wait"); Sometimes this isn't convenient, and you just want processes to get cleaned up as needed. You can do this by establishing a SIGCHLD handler: (void)signal(SIGCHLD, handler); [...] #ifdef __STRICT_BSD__ /*ARGSUSED*/ int handler(sig) int sig; #else void handler(int sig) #endif { while (wait3((union wait *)NULL, WNOHANG|WUNTRACED, (struct rusage *)NULL)>0); #ifdef __STRICT_BSD__ return(0); #endif } These examples are pretty much minimal; real applications generally look at wait status, etc. -=EPS=-

And to answer the question what is destPkg, here's the long answer. chunkPackage is a csh script, so you could see what it does. destPkg is an internal variable successively set to the path name of each chunk package; If however, it does not find any of the chunks, it does not set the destPkg variable. When it finishes the loop, it attempts to create a .last file in the folder of the last package.. presumably to signify that this is the last chunk for the package. It should definetely complain about it much sooner, and it should give a more descriptive error message... -- Takis Mercouris Vanguard Software, Corp. tm@vanguard.com

(And I believe that strongly hints at how the alt resizing would work too) This resizing behavior should be controlled by the window's delegate. The delegate needs to implement a method - windowWillResize:sender toSize:(NXSize *)frameSize the framesize parameter is, in effect, a *proposed* new size for the window (which would take effect when the mouse button is released). However, the windowWillResize: toSize: method can *override* the proposed size of the resized window simply by making an assignment (using the address of frameSize which was passed in as a parameter). (Note the windowWillResize: toSize: method is sent over and over while you are dragging the resize bar---modal loop) A couple of lines taken from my own method will hint at the idea (my window held a matrix of textfields): i = floor((double)((*frameSize).width - oldWindowSize.width)/ (cellSize.width + intercell.width)); (*frameSize).width = oldWindowSize.width + i*(cellSize.width + intercell.width); The first line determines, i, the largest (integer) number of additional columns that will fit in the current proposed window width. The second line changes framesize so that the width would be just right to hold those additional columns (if any). I could have implemented it so that I did not have to store the old window size if I wanted, and that would probably have been more elegant... Basically, you just have to be able to determine how wide the window will be for various numbers of columns and then see to it that framesize is reset to an appropriate size. Of course you still need to see to it that your window has its contents redrawn correctly so you will also have to adjust the number of columns that your browser object has (but this is trivial). In my application I was also able to do this in windowWillResize: toSize: but I doubt if this is the best way. I suspect that it really belongs in another window delegate method - windowDidResize:sender As you would expect, this method executes just after the window resizes. (I am not sure whether the window is redrawn before or after this method, though) Perhaps someone else will clarify this. As for alt resizing, it looks like all you need to do is use the number of columns in the browser and the new width of the window to figure out and then set the various dimensions of the browser. Anyway, that's about it. Hope that it helps! -------------------------------------------------------------------------- Dan Scott me@ienext.unl.edu NeXT mail welcome --------------------------------------------------------------------------

I don t know if anyone still uses Improv on NeXT-Computers and is interested in this stuff. But I think its time for all of us, espically NeXT, to put some code out to give the word Objectware a meaning. If you like the code and/or use it frequently, feel free to send me $15. I wrote a introducing article to the Improv API-Toolkit, which appears in the german mag Workout 4/92 under the title "Entwicklungshilfe f r Rechenkuenstler".

But I currently can't afford to invest much time in unpayed work.

Date: Wed, 6 Oct 1993 23:52:39 GMT Now with NEXTSTEP 3.1, you can include subprojects into your main project using symbolic links. This gives you the ability to share subprojects across different projects. I do this for such utiltity like object collections (gathered into a subproject) such as thread safe List, Storage, etc... in other words any collection of source code that you wish to share amongst different projects. This gives you the following advantages: a) one location for source code (of Classes, etc.. -> reusability!!!) b) consumes less disk space than copying the subprojects would. c) ensures that you are using the latest and greatest version of the shared source. (you can have one person update the source with newer versions) d) ensures accidental source code destruction - have someone else own the subproject that your project links in and have it write protected. To accomplish this you need to do four things. 1. create a symbolic link of the subproject into your main project directory. 2. Add the subproject to your main project using ProjectBuilder. 3. To the main project's Makefile.preamble, add to OTHER_CFLAGS, the following: -I. -I.. 4. To your main project's Makefile.postamble add the following lines: OBJROOT = $(CWD) SYMROOT = $(CWD) That's it.

Date: Thu, 7 Oct 1993 00:22:36 GMT (A) Makefile dependencies are handled incorrectly in NS 3.1: 1. Symptom: - make depend crashed when multi-architecturess are specified. Problem: - $(RC_CFLAGS), the architecture flags, are being added to cc (these are included as $(ALL_CFLAGS) Cure: - Don't add the $(RC_CFLAGS) such as has been modified here file /NextDeveloper/Makefiles/app/common.make: # Build a set of dependencies for current level into Makefile.dependencies Makefile.dependencies:: $(CLASSES) $(MFILES) $(CFILES) $(CCFILES) $(CAPCFILES) $(CXXFILES) $(CPPFILES) $(RM) -f Makefile.dependencies $(CC) -MM $(CFLAGS) $(PROJ_CFLAGS) -I$(SYM_DIR) $(OTHER_CFLAGS) \ $(CLASSES) $(MFILES) $(CFILES) \ $(CCFILES) $(CAPCFILES) $(CXXFILES) $(CPPFILES) \ > Makefile.dependencies 2. Symptom: - Won't build dependencies for .cc and mixed OjC/C++ files. Problem: - Makefile.dependencies rule does not include the -ObjC++ flag, and ProjectBuilder adds .cc files as OTHERLINKED instead of as CCFILES. Cure: - Add the -ObjC++ flag to the $(CC) -MM ... line of found in and add $(OTHERLINKED) /NextDeveloper/Makefiles/app/common.make: Makefile.dependencies:: $(CLASSES) $(MFILES) $(CFILES) $(CCFILES) $(CAPCFILES) $(CXXFILES) $(CPPFILES) $(RM) -f Makefile.dependencies $(CC) -MM -ObjC++ $(CFLAGS) $(PROJ_CFLAGS) -I$(SYM_DIR) \ $(OTHER_CFLAGS) $(CLASSES) $(MFILES) $(CFILES) \ $(CCFILES) $(CAPCFILES) $(CXXFILES) $(CPPFILES) $(OTHERLINKED) \ > Makefile.dependencies This problem is further complicated by the fact that ProjectBuilder does not correctly define the macros set out in the Makefiles. Specifically .cc files should be inserted (into your Makefile) as CCFILES, etc... NOT as OTHERLINKED. Comments: ProjectBuilder should be updated to reflect the new Makfiles. Specifically ProjectBuilder should generate the correct macros for the new Makefiles, such as CCFILES, etc. It would be best from a developer's standpoint, if ProjectBuilder wasn't trying to be so smart about how it will add files to the project. There should be a one-to-one correspondence of "suitcases" to Makefile Macros in ProjectBuilder. For example, there should be suitcases corresponding to CCFILES, MFILES, CXXFILES, CPPFILES, etc... (B) /NextDeveloper/Makefiles/app/basicrules.make incorrectly appends the -ObjC++ compiler flag to .cc and .C files. If you want MIXED Objective-C and c++, you should use the .M file extension. How can I be sure I have compiled clean c++ code, when the -ObjC++ flag gets tacked on? Fix this by removing the -ObjC++ flag: .C.o: $(CC) $(ALL_CFLAGS) $(C++CFLAGS) -I. -c $< -o $(OFILE_DIR)/$*.o .cc.o: $(CC) $(ALL_CFLAGS) $(C++CFLAGS) -I. -c $< -o $(OFILE_DIR)/$*.o I hope NeXT can continue to improve the make facility they have created, and remove the current problems in a future release.

From the NS3.1 developer release notes: [begin quote] - The default search path for cpp-precomp has been brought into line with the default search path for cpp. Most notably, this removes /usr/local/include/ from the standard search path. Developers are encouraged to place local, shared headers in /LocalDeveloper/Headers/ instead. As of release 3.1, the default search path for cpp-precomp is now: /NextDeveloper/Headers /NextDeveloper/Headers/ansi /NextDeveloper/Headers/bsd /LocalDeveloper/Headers /LocalDeveloper/Headers/ansi /LocalDeveloper/Headers/bsd /NextDeveloper/2.0CompatibleHeaders By adding -I/usr/local/include to the cc(1) command line, headers that were previously included from that directory can again be used in this release. [end quote] On our systems (but unfortunately not on Mutz's home machine, until tonight, right Mutz? ;-), /usr/local/include is a link to /LocalDeveloper/Headers anyway. Thus we couldn't figure out at first why things would compile under NS3.1 at the office but not on the home machine :-(. While they're at it, NeXT should also include ~/Developer/Headers in the search path, too. I have a ~/Developer (~/Developer/Apps and ~/Developer/Demos are particularly useful) for working copies and personal development stuff. Don't we all?

However, I also noticed a problem yesterday (I did not get to my NeXT very often during the last two weeks). My time was somewhere around GMT+1300, quite far from the GMT+0100 I usually am. As far as I know the UK DST-switch did not occur yet, so I could be off another hour, but my guess would be that there is no DST-switch in official GMT. Was this switch to GMT+1300 just a bug on my machine (maybe a low battery) or did other people have this problem too? I am running 3.0 black, since my 3.1 did not arrive yet. >I would appreciate any suggestions ... The solution should be to switch to the 'Poland'-setting after choosing the german area on the world-map when GMT+0100 is shown on a popup-button. However this resulted in even more confusion in my case. If anybody has experiences in this line, please CC: your replys to me, since our newsfeed is very unreliable during the last few days.

From: marcus@ursula.ee.pdx.edu (Marcus Daniels) Newsgroups: comp.sys.next.programmer Subject: CLI program to list module addresses Date: 7 Oct 1993 02:40:35 -0700 Message-ID: <290o6j$b0n@ursula.ee.pdx.edu> Summary: Gizmo to look for Palettes, Bundles in other processes Keywords: gizmo thingy I hack on IB enough that I'm bothered by the fact that gdb isn't able to find dynamically loaded palettes after an `attach'. Basically, I think it takes too damn long to constantly be reloading all those symbols into gdb. Anyway, here is a start on a partial solution. A little CLI program that takes a processID. It scans through an apps regions looking for MH_MAGICs. For those regions, it reports the `__text' addresses, along with classes found in those regions. There is an ifdef for whether or not IBPalette subclasses have all the compiled-in classes reported, or just the particular IBPalette subclass (other bundle are always reported). Another ifdef will let you choose between listing modules or classes. Oh yeah, adding `dump' on the command line will dump an apps regions to named files in /tmp. Not really relevant, but if you don't already have a way of doing that, there it is. If you have conventions for where you store development bundles/palettes it makes it easy to write support scripts that transform this output into gdb-commands or other scripts that can be called by gdb user-defined commands defined in a particular project's .gdbinit. Normally you'd take the number reported by the program and use `add-file' with the number as an extra argument. add-file PaletteObjectFile address_reported_by_program This will only let you set breakpoints, it won't let you do things like `call [justloadedclass somemethod]`. I dunno what I have to do to make that work. Please tell me! Doesn't anyone else find the debugging support for `bundle oriented development' woefully lacking?

The fix is to make sure and remove the file "_G_config.h" from $GNUHOME/lib/g++-include since this file automagically created, and also, under the new version it has been moved to $GNUHOME/$ARCH/include for cross-compilation reasons. Since it seems like you are trying to install the new version over an old one, that means that the old _G_config.h wont be removed but instead included before the new one, giving rise to frustrations at best. The makers of libg++ suggest you totally wipe out old versions before installing new ones. Dont blame me for this, however.

I may have mistaken your problem, but if you are talking about C-style #define - Macros, you won't be able to see them in the compiled code at all. So, you won't be able to debug them with a debugger, really. What you can do is take a look at the proprocessor output / listing file. The cc should have an option for generating a listing of your code after the macro expansion. That's where you can check out the code that will be compiled. Using that, you may be able to understand what kind of executable the compiler generates. I don't know if that's the core of your problem, but I'm afraid that's all you can do about macros in c.

Of course, it used to. But this got taken out for 3.1. In my opinion, it is now inconsistent that the linker searches /usr/local/lib but the preprocessor doesn't search /usr/local/include. I asked NeXT about this prior to the final 3.1 release--it seems most of the people there used /LocalDevelopers/Headers instead of /usr/local/include and so hadn't noticed the change.

The popuplist and the button to which it is attached are not the same object. Using command keys messages the target of the menu item but does NOTHING to the button. The best solution is to connect the button to your controller (target) object as an outlet and in your target action, set the title of the button as well as performing the selection. Jon

Looking over the current version of RCS, there seems little reason or need to go to CVS. I have CVS and RCS installed now, and the only difference seems to be that CVS keeps the source in a central location, making backup extremely easy. The current RCS when used with gnudiff claims to work even with non-text files, which would mean tiff files and such would work fine. The CVS Palette that has been made available to 'protect' the CVS/ directories inside the .nib files could easily be modified to work with RCS directories (at least from the description of what it actually does). I guess my questions are... 1. Are there any obvious reasons to use CVS over RCS other than the central repository issue... 2. Does anyone have any suggestions about where in the NeXT directory structure would be a good place to keep the source repository? 3. Is there anyone interested in developing a front-end for CVS that would allow drag and drop check-in/out/update/commit? 4.

The 16384 comes from a minimum of one "text" (read-only, shareable) page for code and constants, and one "data" (read/write, private) page for initialized variables. Having executables organized as mappable pages for performance reasons is hardly a new idea, it's just that most other systems that do this use smaller pages. >Is it possible to strip binaries fully?

These aren't executables, but relocatables. Basically object files with no unresolved references. When you exec one, the system has to allocate memory and link edit the relocatable-- a rather inefficient process. It's only worthwhile for very small, infrequently used programs, and there are all sorts of restrictions. Some of them are fairly obvious (e.g. why you can't link an Objective-C program this way) to somewhat obscure (there can be problems when relocatables are started by inetd). -=EPS=-

The two front ends you should look at are package, and chunkPackage. These are both csh scripts. package takes the path to the app you wish to make a package for, the name of the directory you would like to make the package in, and the name of a file containing an info-file describing the app. It has other options: just run the command with no args to see a usage message. For information about what an info file should look like, try looking at those in packages already installed on your system in the /NextLibrary/Receipts directory. chunkPackage takes a package and a size (in KB), and splits it up into pieces that can be stored on separate floppies. Again, usage info on the other options can be gotten by running with no args (or reading the script of course). I must admit I have had trouble getting chunkPackage to work correctly under 3.1. 1. I had to dramatically undercut the size argument to get a 5 disk package in small enough pieces so that all would fit on floppies. 2. The floppies would not install correctly via the installer app because a process kept files open on the first disk, and thus would not let me go on to the second one. (p.s. this one had both preinstall and postinstall scripts in the package) Hope this helps. Anyone had any better luck with large floppies? -- ___ ___ mail: uunet!phcs!jq PHCS, Inc.

So this request is for people with non-Unix, non-MSDOS systems. If you help out, you get - some decent code management tools on your computing platform - a free copy of the final book (and code) from OReilly and Associates - and your name in the preface of the book. If you're still interested, please read on. ------------------------------------------------ I've just written a book called "Code Management Tools" for multi-platform development environments. It covers source code control, directory structures, automatic generation of complete makefiles, and practical file sharing (code reuse) techniques. It also discusses design issues for code management systems. The book is intended to be a practical, one-stop-shopping product for multi-platform code management tools. It's about 400 pages long, and includes source code for about 30 software tools (including a multi-platform version of RCS), so that pople can port the code to machines that I haven't got access to. I've already ported the tools to MSDOS (for Borland C 2.0, Microsoft C 6.0) and to Unix (Sun4 under GCC). The problem is that I don't have access to Macintoshes, Amigas, Ataris, Next machines, VMS machines, or any other such machines. So I'll never be able to port the tools to those platforms. (I don't have the necessary knowledge to port the code to these machines, either.) So I'm asking for knowledgeable, serious volunteers to review the book and port my ANSI C code and batch files to their machines, so that I can include the ported code with the book. (Many of the tools are batch files and shell scripts that call freeware tools such as sed, gawk, find, and fgrep, so porting the tools shouldn't be that hard.) My hope is that individuals, or small groups of people from various user groups for these various computers, will undertake the job of porting the scripts to their computers. That way, people who own those computers will have access to more software engineering tools on their particular computers. As you probably know, there are very few---if any---good, low-cost software engineering tools for many of these computing platforms. That's why I wrote this book, and included the source code--to address this need. I hope you'll help if you can, even if you can only port a few of the tools and scripts. (Porting RCS---which I didn't write---will be the toughest part. Let's say that it's "challenging.") OReilly and Associates will give you recognition in the preface, and a free copy of the book if you send them your comments in written form. Nothing too fancy is required---but it's got to be a serious report. What we do want are people who'll help us produce a better book and software product. What we don't want are people who just want a free copy of the draft book. Please respond to jameson@cal.isac.ca if you are interested. Thanks kj

Stuff about RCS vs CVS > 1. Are there any obvious reasons to use CVS over RCS other than > the central repository issue... Here are my 2 cents worth. Firstly, our project uses three programmers working concurrently. That means that the simple locking paradigm used by RCS means that two people can't be working on the same code at the same time. CVS allows this because it makes a local copy of the source. CVS also handles multidirectory projects like NeXT apps much more simply than RCS does. The problem with CVS is that it is very complex. To use it simply from ProjectBuilder required a lot of Makefile hacking to make new targets for CVS to work with. Art Isbell's cvs.postamble was a start, but still leaves several problems. Generally I would say that RCS is fine for single programmer projects, but you need more for multi-developer work. > 2.

Probably /LocalDeveloper would be good, although we don't put it there cos we use a shared disk and we put it there. > 3.

Is Edit.app going to be nasty and nuke any CVS directories that are > contained withing .rtfd files? The simple answer is yes, the same problem as exists for InterfaceBuilder. Our makefile sorts that out. The only other comment I have is that we are looking at moving to another system called Shape - It's free, does all that CVS does and much more. It controls object and executable files as well so if someone else has just built, you don't have to. For you it is probably hitting a tack with a steam hammer, but we will probably start using it soon. It also has a proper API, so developing fron ends is much easier than for CVS. Hope that helps.

The docView of a ScrollView is actually a ClipView, and must remain so for the ScrollView to work. What you want to replace is the docView of the ClipView, so the code should be oldView = [[theScrollView docView] setDocView:myView]; (whew!)

I'm really looking for something that is more graphically oriented, and I'm probably going to end up contracting someone to do a front end.

Instead of complaining about how NeXT isn't provided major new sets of features, just do `simple' things, like making it possible to use the runtime and InterfaceBuilder in a language independent way. >5- Fixing the infamous Text Object Damnit. >6- Better security in distributed ojbects Ho hum. Checklist item, no practical significance. >7- More objects in the libraries: General purpose String object would be a > good start A little late for that, eh? Even less important than the `distributed object security' nonissue. For the near term, I'll take (5), (1), and language independence (in that order) (6), (7) are total nonissues. They can be taken care of perfectly well by developers. For peace of mind, I suppose NeXT could provide an abstract class for authetication, or something. Regarding linking speed, Project Builder and GDB should polished to support bundle oriented development more easily. Dynamic linking should be tuned, over ordinary linking. IMHO: - The extensions supposedly added to PB for PDO should include an `install' that can optionally launch object servers. IB palettes should also have a launch target. The RC scripts should have simple additions to launch programs stored in certain directories (or something more general). Note this is not the same as automatic Workspace app launching. Some clean way to ensure that `object servers' are launched on bootup. Perhaps an inetd type superserver could be used. - It wouldn't be too hard to add information to the Mach-O OBJC segment so that dynamically loaded code could include all the directory references and other info so that gdb wouldn't have to hook rld's in order to load symbols. It would be better if you could attach to a process and have gdb able to access all the relevant executables and shared libraries (for symbols). Then, it would be good to have symbol loading go much faster. Some other platforms have gdb options for memory mapped symbol files, and various optimizations to enhance symbol loading. NeXT could no doubt come up with something even better. - Related to the previous item, it would be good if there was a documented protocol for communication between the editor and debugger. Once there was some sort of established protocols, then integrate MallocDebug, AppInspector, and possibly profiling app into this scheme. I'm sure there are plenty of folks who would like to have Emacs work cleanly with Project Builder. If not Emacs, it would at least open the possibility of a debugger app and/or Edit bundle extensions. My thinking with this isn't so much NeXT should provide all new apps, but enable developers to come up with their own solutions. I want NeXT devoting all its energies to 4.0 (especially the OOFS), improved APIs for existing apps, and enhancements that other developers can't (e.g. an RCS would be hard for anyone but NeXT to do without writing a new PB). marcus

He then goes on to explain his first attempt at this. What John was trying will not work. He wants the Text object, but he has tried to replace it with some subclass of View. He didn't realize that he was replacing the text object. When you drag a ScrollView off the IB palette, its docView is a Text object. What John wants to do (and it isn't for the faint of heart) is try to subclass Text, override -mouseDown:, and do his stuff there. Then he needs to set up a ScrollView that contains one of his custom Text objects as the docView. While subclassing Text is not something I would recommend for everyone since the Text object is kind of nasty, getting the behavior John wants shouldn't be too hard (maybe). ____________________________________________________________ Mike Ferris When you're up to your ass in mike@lorax.com alligators, it's hard to remember Rubicon Software your initial objective was to (510) 652-2039 drain the swamp.

But, I don't quite follow the "remove the notion of header files" from IB part of it. I, at least, like using .h files. My current MO is something like: 1) Use IB to "design the interface" (this is something like doodling on scratch paper until I get a look that I like) 2) Write the classes I will need (both .m and .h) files 3) Parse the .h files and do the "wiring" I really don't understand how > ... remove the notion > of header files from InterfaceBuilder.

Having just had a very bad experience with a RCS front end on NEXTSTEP, I agree there needs to be better integration between Project Manager and RCS... but I think that this needs to go one step further, and be Project Manager and whatever. Its been argued that Project Manager should have an API. Since the Project Manager application is something that it would be next to impossible for a third party to come out with, there is definately a need for this added functionality, and it would not step on any toes. Heres a good question, what sort of API is needed?

Its undocumented, and unsupported, but from a posting in next-prog mailing list there is a potential for it to be there in the future. In the meantime, you have a few third party solutions for Strings OTStrings DolphinKit MiscKit (yeah, got to plug that one!) and many of these kits offer additional objects as well. As a matter of fact, I think (OK, it was suggested to me) that the problem with the whole ObjectWare market is that there are few standards and its difficult to get the information out there that they are available. A central software house that sells such objects would be very useful. It could ensure inter-operability, suggest standards for interfaces and stand behind the objects. Almost like APDA in the Apple world. It would be nice if the AppKit grew, but I'm not sure what needs to be added. Many of the obvious things.. serial port connectivity, TCP/IP communication, strings, unix processes, streams are available from third parties. Perhaps NeXT should concentrate its extensions on areas of UserInterface? That would ensure a consistant feeling between all apps that use the same features.. Things like Inspector/Switch view Tri state buttons enhanced Scrolling List file/images/sounds wells Workspace shelf many of which are available now either free or as MiniExamples, but have not been 'wrapped' into the Appkit. The real question is what happens to those third party developers who have Strings solutions now, when NeXT comes out with theirs? My suggestion there is to get the commercial implementors together, with NeXT, and hash out a string object that is designed by all, but actually written by those commercial developers. NeXT licenses it, includes it in the AppKit. Developers don't get hurt, NeXT doesn't get hurt, and we get a funky new object. Then those same developers can sell their additional string functionality to the programming market as required.

That feature wouldn't have to disappear, although honestly, I think there would be a number of nicer ways to manage class structures. Nothing jumps out at me as causing fatal backward compatibility problems. You'd just want to make sure that in cases of duplicate information, there was (artficially enforced) consistency. In any case, I'm not necessarily suggesting a .nib style of storage for class information, something textual very much like existing .h's would be one alternative. The goal would be just to store class info in an external lanaguage-independent form. It would be possible, obviously, to have makefile dependencies that updated ObjC header files as we use today, but that would be for superficial reasons. I'm sure I'm overlooking some tougher issues, but in the big scheme of things I bet this would be an easy one. Making a portable runtime would surely take some work, though. NeXT wouldn't have to do that. [munch] >makes my life any easier (it seems to make it worse). Is this >another thing that only people with a Smalltalk background understand ? Perhaps a slight disruption, but it _could_ be made to work almost identically. The wins as I see it are: 1. There is a simple, fixed format that _only_ contains class info and/or method info. I've always found the mushed together macros+static variables+class info kinda unsatisfactory. These could be conceivably used directly by as (archived) class-objects by an OOFS. Less ambitiously, they would be class-browser-manager `documents'. Having these abstractions might make it easier to keep NIB data up to date. 2. Language independence. The read/write/finishloading/awake system would seem to work equally well for most any language. Some glue might need to be built into NXBundle. Performance zaps could happen (compare to the first expression in Mathematica), but theoretically it would work, no? Imagine being able to make connections (using enhanced connection inspectors) to objects running in a CLOS/Dylan (DO based server?), tcl, SmallTalk, etc.. Obviously OO languages would lend themselves best to this. Provided each add-on language still communicated using the runtime, what about IB isn't clean enough to support this? Developers would still have the performance/proprietary advantages of Objective C while having the option of, for instance, of communicating `actively' with an interface to a LISP expert system. Well, there isn't any use in trying to anticipate the best uses for language independence, my point is just that it (at least initially) seems to be a pretty easy thing to do. And it opens up lots of possibilities, all without introducing many (any?) questionable constructs. O.k., o.k. burst my bubble. I'll shut up. I've been partying too much and I'm troubling you folks with my delusions.

Not to mention compiler state, error info, etc.. There are various levels of granularity for that, but at least `active', `inactive'. The linkage between IB and PB is pretty loose, PB might think in terms of classes as well as files. Crafting an API including that sort of info could be useful (& tricky). And is it a good thing that a Unix `make' is spawned by ProjectBuilder? What if PB took over make's functions? [One thing that bugs me is that PB can get confused if you start/stop builds, sometimes it just hangs -- certainly just a bug, but one that wouldn't exist if it was all one program]. Also, The makefile system is rather stretched, if make is so important, why not use a powerful one like GNU make? Big job, a good time to address these issues would be when NeXT works on RCS. Does anyone have experience with the revision control system that NeXT was considering having ported to NEXTSTEP? Is it based on RCS/CVS? >> 2- Objective-C class Browser: such tool has been available for years in C++ > Having never really seen one of these C++ monsters, what difference is >there between that Browser and HeaderViewer?

Is a String object really such a big deal? The ones I've seen aren't necessarily duplicates, they each have different emphasis (i.e. garbage collection, safety, etc).

It's funny they should pick the Workspace Manager for this example, since it actually subtly violates this rule. To see this, single-click on an icon on your shelf. It moves the scroller below to that path and makes it the currently chosen file. But if you double-click on it, it will open the document/app *without* making it the current document or file. In other words, the single click is ignored and the double-click is processed instead.

Shape is available from various ftp sites including gatekeeper.dec.com:/pub/plan/shape/shapeTools-1.4.tar.gz. Below is the readme file from the shape distribution. -------------------------------------------------------- This is README for shapeTools-1.4. It contains general information on ShapeTools (we also refer to it as "shape toolkit") and an overview of its parts. The file "INSTALL" helps you installing the toolkit on your machine. It also gives hints for solving portability problems and describes the procedure for porting the toolkit to a new operating system platform. If you used ShapeTools-1.3 (or earlier versions) before, you should read "CHANGES-1.4" to check, what has changed since 1.3. *** The file CHANGES-1.4 contains important information *** *** on migrating from ShapeTools-1.3 to ShapeTools-1.4. *** Before installing and using the shape toolkit on your computer, you should also read the file "LICENSE". In the file "FUTURE", you find important information on how the ShapeTools development will be carried out in the future. You can also find the address of a company offering commercial support for ShapeTools there. If you have any questions, hints or bug reports, you may contact us via: Tech. Univ.

Submissions to the mailing list are to be sent to "shape-l@tubvm.cs.tu-berlin.de". General information: ==================== ShapeTools is a collection of programs to support software configuration management in an UNIX environment. It consists of a set of version and attribute control commands, and a configuration interpreter and build tool ("shape"). The toolkit is integrated on top of AtFS (Attributed File System), a storage system supporting multiple versions of files and associating an arbitrary number of application defined attributes of the form "name=value" with each version. AtFS comes as a function library that is meant as an extension to the UNIX file system. It does this without the need for kernel modifications and without imposing any restrictions to existing file system applications. ShapeTools is designed to live meaningfully together with any other UNIX tool operating on regular files. This distribution also contains a prototype for a comprehensive change control and release management system designed to manage the evolution of system releases in multi programmer software development efforts. The ShapeTools version and attribute control system ("shape_VC") ---------------------------------------------------------------- The ShapeTools version and attribute control control system is a set of UNIX(1) commands. Shape_VC offers version control functionality and direct access to user definable attributes associated with each version. In detail, shape_VC comprises - storage and retrieval of multiple revisions of files. - a built in status model for revisions. (States: busy, saved, proposed, published, accessed, frozen) - documentation of change histories. - synchronization of concurrent updates to a history. - symbolic names as version number aliases. - a flexible version selection (version binding) mechanism driven by general version binding rules. - a basic network user concept. - full (read and write) access to user definable attributes. The last point in the list, the attribute control, deserves some more attention. As the underlying storage system (AtFS) supports associating any number of attributes with each version, shape_VC uses this mechanism to allow the user to attach his/her own management information in form of attributes to stored revisions. The attribute mechanism supports - genuine attributes (<name>=<value>) where the attribute value is given statically. - execution attributes (<name>=!<executable_program>) where the attribute value is determined dynamically by executing a given program or shell script and catching its output. - file reference attributes (<name>=^<filename>) where the contents of a file is taken as attribute value. The file contents is read on every attribute access. - version reference attributes (<name>=*<network_pathname>) where the attribute value points to another version. The toolkit character of the system allows to use it directly by calling the commands from the shell, or to build a customized environment on top of it. As an example, we wrote some code to provide direct access to the system from within GNU-Emacs. The corresponding emacs lisp code is contained in the distribution. The Attributed File System (AtFS) --------------------------------- AtFS is the base abstraction of the whole toolkit. It provides uniform access to immutable revisions of files stored in special archive files (in a directory named "AtFS"), and mutable regular UNIX files. Consequently, the AtFS based toolkit lives peacefully (and meaningfully!) together with standard file system applications (editors, compilers, formatters etc.). Cooperative work within projects is supported by a build-in status model, controlling visibility of version objects, and locking, a primitive form of "long transactions" for synchronizing concurrent updates. The general concept of application defined attributes provides a basis for storing management information with versions and passing this information between individual tools. This mechanism is useful for building integrated environments from a set of unrelated tools. AtFS also supports derived object management, i.e. it maintains a cache of multiple versions of compiled object-files (e.g. compiled c-files with different compile switches). People with sophisticated requirements may also add their own applications on basis of AtFS to the toolkit. There is a fully documented C-language interface to AtFS, on top of which all the toolkit programs are built. Additionally to the AtFS C interface, there is the AtFS toolkit library interface (also in C), providing higher level functions such as the version binding mechanism. The configuration management and build program ("shape_CM") ----------------------------------------------------------- The shape_CM component consists of the program "shape", performing - identification of system components, - component version selection, - variant control, - driving transformations (eg. compilations) and - recording configurations (for later rebuild) for the software system to be built. Shape_CM uses, similar to make, a description file named "Shapefile". In fact shape_CM is upward compatible to Make in that it can properly handle conventional Makefiles. The Shapefile however, uses Makefile-style dependencies as (versionless) abstract system model and employs version selection rules to dynamically bind particular versions to the names listed in the system model. The version selection mechanism exploits AtFS' ability to maintain any number of arbitrary attributes for objects in the object base. On special request, shape records an identified configuration in a configuration identification document (bound configuration thread - BCT) which has the form of a completely bound Shapefile (all object-instances are explicit). One of the most useful features of shape is its support of various variant administration techniques. Shape makes no assumptions about the semantics of the variant notion other than having alternative (conceptually equivalent) instances of the same concept ("module"). Despite the particular semantics of a certain variant-concept, there is a small number of techniques to physically handle variants. These techniques are what shape supports. Most commonly used techniques are: - equally named files in different directories - one source file representing multiple variants that are extracted by a preprocessor using different preprocessor switches (e.g. conditional compilation) - one source file processed by different tools or different tool versions/variants (e.g. cross compilation, different coders) - combinations of the above. Shape includes a variant definition facility that allows very flexible and convenient handling of all of the above variant administration techniques. The ShapeTools release management system (shape_RMS) ---------------------------------------------------- Enclosed in the distribution is a prototype for a configuration management environment to be used for constructing system releases in complex (multi programmer) software development projects. Using this environment does not require any experience in writing Shapefiles (resp. Makefiles). The environment consists of templates for a Shapefile and a Makefiles and of a library of Shapefile fragments for project wide use. The shape_RMS supports: - a fully automatic global release building mechanism with automatic release number generation. - automatic generation of prereleases as systematic preparation of releases. - construction of subsystem releases and prereleases - system building and installation by shape *and* make - standard version selection rules - a project wide unified variant raster - built in standard functions for cleaning up, generating tar or shar files, determine file dependencies etc. Each directory where a part of the managed system is developed, has to be equipped with a Shapefile and a Makefile derived from the given templates. In the normal case, the derivation just requires setting a few macros. Shape- and Makefile are kept redundancy free, the Makefile is inserted in the Shapefile via an "include" mechanism. The management of a Shapefile *and* a Makefile (although the Shapefile alone should be enough) implies, that certain system building functions can also be performed by "make". This is especially important for producing self contained releases (buildable and installable on shape-less computer systems by use of make) from the projects development area (managed by shape).

The tutorial shall help you to learn to use the toolkit in your development work.

On BSD like systems, this can be organized by using symbolic links. Vanilla System V systems do not support symbolic links, so we introduced a mechanism allowing the "AtFS" entry in a directory to be either a subdirectory (the normal case) or a regular file containing a directory name. The latter case is handled like a symbolic link and archive files are searched in the directory named in the "AtFS" entry. Acknowledgement =============== Version 1.0 of the shape toolkit was a result of the UniBase project, a joint research and development project funded by the "Bundesministerium fuer Forschung und Technologie" (BMFT, Federal Ministry for Research and Technology of West Germany) under grant number ITS-8308. The project aimed at the development of a large scale industrial software production environment. The current work on the toolkit (version 1.1 and newer) is mostly part of the STONE project (A STructured and OpeN Environment). STONE is a scientific project aiming at the construction of a generic software development environment kernel. The STONE consortium consists of nine German universities and research institutes, three of them from former East Germany. STONE is also funded by the BMFT under grant ITS-8902E8. Further contributions come from members of the REX project (Reconfigurable and Extensible Parallel and Distributed Systems) funded by the EC as ESPRIT Project 2080, and from faculty members of the TU Berlin. Thanks to the various people who sent bug reports, hints and recommendations. Thank you also to the moderator and reviewers of comp.sources.reviewed, who made very valuable comments on shapeTools-1.2. They definitely had no easy job reviewing shapeTools in it's whole complexity. Special thanks to Steve Emerson (steve@unidata.ucar.edu) who rewrote parts of the shape program. Juergen Nickelsen (re)implemented various parts of the toolkit as member of the STONE project crew. Unfortunately he had to leave the project due to funding problems. We hope to get him back into the ShapeTools family as soon as possible.

If a class calls a function that isn't linked into the main application at compile time, rld() returns and error: Undefined symbol: (I think. I'm reciting from memory). Of course, it never specifies the symbol, but I can usually figure out what it was. So, how can I link a *specific* function into a bundle? For example, I want to call kill() from a dynamically loaded class. It's not linked into either the main application, or the dynamically loaded class. When the main application starts and dynamically loads my class, I get the rld() error, and everything spews. So, how can I force kill() to be linked into the bundle? The only solution I've found so far is to have a "dummy" function in the main application with kill() in it. This forces kill() to link into the main application, but this is an unacceptable solution.

Don't forget the Stepstone kit, too. MiscKit annoys me because of how I read the license/header: I cannot use this in a for-sale product without permission from the author. My read is that this is not free software. I don't want to sell MiscKit as my own, nor do I even want to change it in any way. I just want free software to be free from hidden license requirements. If it's public domain, I think it should be released without limitations. I have been using MiscKit (at least the String class) in a personal project, which will never be sold (I'll be upoading it to the archives as freeware). My other classes are going to be free.

Everything was fine, no runtime errors except for some compiler warning for re-declaration of some varibles or functions such as 'name' which was defined in Object class, and 'state' in some IB objects, etc. However, the program code was not executed as I expected, so I ran GDB from PB and Edit, and I ended up with a messed up symbol table I guess, The program counter was jumping thru a sequence of assignment statement, and sometimes enter an invalid block. This all happened in the same objective-C function block. When I was convinced that there's nothing wrong with my program, I discovered the inconsistency between *.[h] and IB. (It shouldn't matter though, 'Coz all the newly added stuffs are not Interface related, I meant local varibles and methods). But I gave it a try anyway, Luckily I got away with it for the first time. Now the same phenomenon is happening again that I have no clue at all. The only thing I'm sure is that all the *.[h] has been dragged/updatted in the Class case of IB and saved to ensure consistency. What can you do when GDB Next/Step you thru a jumping sequence of the program code? Plus, some weired things such as: i = [myObject cost]; /* which returns a object varible */ when printed from gdb: [myObject cost] = 100; i = 0; Any Help would be highly appreciated, as I'm totally lost. Thanks, Gary

Bruce and everyone I'm pretty confident from my use of MiscKit, and ALOT of communication with Don Yacktman, that the MiscKit IS intended to give you exactly what you are looking for, the ability to ship a commercial product with MiscKit objects in it without permission, provided that someplace in the documentation you mention that there are MiscKit objects in your program. You aren't obligated to give them the source, return changes to MiscKit or any of those other GNU things. I'd suggest that if you have concerns like this, you should contact Don, or get the current MiscKit from ftp.byu.edu which has the new license agreement. There is a difference between Public Domain (ie. giving up the Copyright) and what the MiscKit is offering, but its so very small. -- - Scott Anguish - sanguish@digifix.com (NextMail) next-announce@digifix.com (comp.sys.next.announce submissions)

Implemetations discussed include NeXT, Gnu, Stepstone, etc. comp.object Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original comp.sys.next no longer exists--do not attempt to post to it.)

I just wanted to change something in Rosetta and had to rewrite the dragging-mechanism. I tried both suggested workarounds for dragging into an appIcon - cheating the window-object with object_stInstanceVariable([NXApp appIcon], "delegate", (void *)self); - using the contentView of the appIcon-window instead of the window for registering for dragging and both workarounds only work, when the program is started from gdb or a shell. (dragging into a normal window works underall circumstances) When started from workspace, the contentView seems to get no draggingEntered-messages. After discovering this, i tried the same with my Squash 1.0g (compiled for 3.0), which doesn`t accept drags since i upgraded to NeXTStep 3.1. And its the same! Started from workspace --> no drags are accepted Started from a Shell --> everything is fine Anyone who can help???

I am porting an app which wants to draw 3D stuff, but it has very different semantics than the 3Dkit in that the control flow needs to come from the program rather than from the event loop. (Ie I need a 'direct mode' for doing rendering such that I can make renderman calls such as RiPolygon from within a function and expect them to be drawn on the screen.) The 3Dkit is unfortunately insufficient, because it requires all rendereing calls to be embedded within the renderSelf: method of a shape object, which get called indirectly when the N3DCamera is asked to display itself... no good. What I have done is to setup my own N3DCamera, and then when I want to draw in it, I do a [myCam lockFocus], followed by the Ri.. calls which I want to make, and then ending with a [myCam unlockFocus] [myCam flushRIB]. This seems to work reasonably well and as expected, except for the fact that the camera you are rendering into does seem to store some state such as whatever you declare in the 'camera' block (ie RiProjection, RiClipping, etc..) as part of the QRM 'context' which can't be undone. This becomes a problem when you try to have multiple cameras w/ different projection options. So I thought, OK, just create a new, seperate context using N3DContextManager for each camera and switch to it manually before rendering. Here is where my current dilemna is.. as far as I have been able to tell, the setCurrentContext: method does NOT appear to work in that it doesn't change the context!! Also, if I force a change in context on the QRM side using RiContext(), nothing gets displayed in the camera.... So.. does anyone have any experiences, tips, or suggestions in dealing with multiple cameras/contexts using QRM without the 3Dkit??? Please?? Dave- if you read this, could you please tell me what I should be doing?!

On UNIX, if an EMT instruction is executed, the process gets a SIGEMT signal and the process is stopped. SIGEMT has probably been recycled to be used for some other trap instruction in modern chips, just as SIGIOT, etc. have been. Basically, it should be treated the same as SIGILL -- that is, your process executed an illegal machine instruction.

People who use these features should know that they have a serious problem: if you use dynamic linking/loading of object code, Mach has to copy the object code into your memory map and then page it out to the swap file. Normally, code is "pure" and Mach can page it in from the executable itself. Pure code never needs to get paged out; it just gets overwritten, since the memory image is never different than what is in the executable. But when you use dynamic linking/loading, code pages get dirty (with relocation info), you have to page them out, your swap file grows, and performance goes south. -- ................................................................simson

It should be in pub/next/submissions at both sites until the moderators migrate them elsewhere. Here is some info from the ReadMe file: ------------Begin README--------------- MOKit Version 0.9, release 1 ---------------------------- Welcome to the first release of MOKit! What is MOKit? -------------- MOKit is a set of objects which I have written. I am making it available for use by whoever wants to use it. Full source is provided for all the classes, palettes, and examples. The following notice appears in each header file in the kit. // ABOUT MOKit // // MOKit is a collection of useful and general objects. Permission is // granted by the author to use MOKit in your own programs in any way // you see fit. All other rights to the kit are reserved by the author // including the right to sell these objects as part of a LIBRARY or as // SOURCE CODE. In plain English, I wish to retain rights to these // objects as objects, but allow the use of the objects as pieces in a // fully functional program. NO WARRANTY is expressed or implied. The author // will under no circumstances be held responsible for ANY consequences to // you from the use of these objects. Since you don't have to pay for // them, and full source is provided, I think this is perfectly fair. As outlined above, anyone is free to use these objects in their own applications. There is NO WARRANTY express or implied. Now on to more interesting details. What classes are in MOKit? -------------------------- MOKit currently contains 7 classes, one palette, and one example app. There is full Next-style class documentation for each class. Here's a brief description of each class included in this release: MOString - yet another string class. This class basically provides a wrapper for a c-style null-terminated string. The class knows about Next-style unique strings as well. Many methods for accessing and modifying the string are provided including a fairly complete set of covers for the regular ANSI string library functions. MOSybaseString - a subclass of MOString which adds a few methods for dealing with string's that will be used to build qualifiers for Sybase. Primarily the class provides a way to make a given string case-insensitive SQL-style (eg. changing "a" to "[aA]"). It also provides a method for converting unix style wildcard characters into their SQL equivalents. MORegexFormCell - a subclass of FormCell which adds input validation via regular expression pattern matching. Each cell can have a list of regular expressions associated with it. When the user tabs out of the field, the entry is checked against the regular expressions. The entry must match at least one of the cell's expressions or it is not accepted and the field does not allow editing to end. It is possible to check a wide variety of input formats via regular expressions. MORegexTextCell - a subclass of TextFieldCell which is to TextFieldCell what MORegexFormCell is to FormCell. MODateFormCell - a subclass of MORegexFormCell specifically set up to check dates. Dates cannot be checked completely by regular expression matching, so this class lets regular expressions do what they can and then finishes validating the date. The class also allows customizable reformatting of entered dates via a printf style format string. MODateTextCell - a subclass of MORegexTextCell similar to MODateFormCell except that it is a TextFieldCell by ancestry. MOMatrix - a subclass of Matrix that allows variably sized rows and columns. What else is in MOKit? ---------------------- As well as the class sources, headers, and documentation, MOKit contains several other peices. There is one palette which has several Forms with preconfigured MORegexFormCells in them, several Matrix's with preconfigured MORegexTextCells in them, one Form with a MODateFormCell in it, and one Matrix with a MORegexDateCell in it. The palette provides attribute inspectors for each of the four cell classes. There is an example program which demonstrates the use of MOMatrix. There are separate bundles for each class in the library. The bundles are not for use in normal apps. They are useful for apps that will do a lot of dynamic loading and for IB palettes. See the REDAME file in the Bundle directory for more info. How do I install it? -------------------- There is a master Makefile in the top-level MOKit directory (the directory where this README file was). The default install location is various directories under /LocalDeveloper. If you want to change this, edit the first few lines of the master Makefile. Once the installation locations are set up like you want, cd into the MOKit directory and type make install. This will build all the necessary binaries and install everything (library, headers, documentation, and palettes). How do I uninstall it? ---------------------- cd into the top-level MOKit directory and do a make uninstall. How do I clean out the object code and binaries and such? --------------------------------------------------------- cd into the top-level MOKit directory and do a make distclean. What else can the top-level Makefile do? ---------------------------------------- These are the supported targets... lib: builds the optimized library bundles: builds the individual class bundles examples: builds the example apps (depends on lib) palettes: builds the IB palettes (depends on bundles) all: build the lib, bundles, examples, and palettes targets install: installs the library, docs, headers, and palettes (depends on lib and palettes) uninstall: removes all traces of MOKit from the installation area distclean: removes all derived and backup files from the MOKit distribution directory More specialized control over building can be accomplished by using the Makefiles in the individual directories. Specifically, debug and profile versions of the library can be made. The top-level install target will install any versions of the library that exist when it is called. It will only create the optimized version, though. So if you want to install all three, first make the debug and profile versions using the Source directory Makefile, then use the install target at the top level. Future Directions ----------------- I plan to keep adding objects to this kit. I have several in the works now that didn't quite make it into this release. This release is number 0.9 because it will be the first release to be used by people besides me. When I have had some comments and bug reports, I will create a 1.0 version. For now, consider this a beta release. I have also considered merging this project with the MiscKit effort currently being organised by Dan Yacktman. I want to wait until their policy and such settles down, though, and I didn't want to delay letting people at these objects, so here they are. Let me know what you think! Well, that's all for now. Please let me know if you use the kit. Bugs, comments, and suggestions can be sent to: Mike Ferris mike@lorax.com Happy hacking -Mike ------------End README---------------

An important point, nonetheless the recent context of the discussion (and your article) was developer productivity. In that context, bundles greatly reduce linking time. The incremental linking procedure for subprojects is the same as the bundle linking procedure. Therefore, a finished app can be easily reorganized as necessary to optimially balance the tradeoffs between static and dynamic linking. Another problem with bundles is that you can't use the class info you load in literally. You have to do everything indirectly, through class objects. It would be better if it were possible to build two part bundles -- so that the objc-class-sections could be linked ahead of time (either dynamically or statically). (I suppose that is possible now, if you wrote a section extraction utility and substituted an install program). marcus

Don't you think this is overstating this a bit? I mean what you say is true, however, once you've loaded, relocated and paged out the code, this really isn't a whole lot different than the situation you've got with "pure" code. The differences being that the code lives in the swapfile (which is potentially larger now) and you swap from the swapfile. Big deal. Where did my performance go south???? The point being, after you've reloc'd the code, it'll get paged out *once* and then only paged in as necessary (just like "pure code").

Now, I tried to compile zmodem (yes, I know about the serial port problems) for NS/Intel 3.1. I get a lot of error messages and no binary - I think that this may be the result of new include files. (I have no problems with simple C programs which don't include lots of things) - Includes for the zmodem "include" - #include <sys/types.h> #include <sys/stat.h> #include <termio.h> #include <sys/ioctl.h> (There seems to be a termios.h in 3.0 but changing the includes to that spelling made no difference.) Can anyone clue me in on what is happening - Obviously this is a concern for more than just compiling zmodem sources. I suspect problems with other programs. (I did have problems on 3.0 black hardware compiling g++lib sources and I believe that someone pointed out some changes in includes - But, as it turned out, I was sent the new files and didn't need to carry that matter any further.)

Yes. At expo, in the Developer Conference, it was recommended that you use bundles while developing, so that the code can be incrementally linked. This improves the development cycle time. Then, when you are ready to go into production, you should statically link in your bundles. (It's still good to leave the API open, though, so that your users can add to the app, too.) As an example, take an app with lots of tools like IconBuilder. What should be done is to statically link in all the tools that come with the distribution, but still allow the user to link in their own tools via the API. Of course, there are time when you don't want to statically link, or vice versa, and you have to strike a balance that works in the particular application, but the general idea is sound. Performance is most important in the production code; I can stand lower performance while I'm debugging my algorithms... it seems a good trade off to me. However, Simson's point about dynamic linking being a dog is true if a developer doesn't go to the trouble of statically linking once testing is done. Note that there are other tricks you can pull to increase performance of statically linked stuff, too, like scatter loading, etc., as discussed at expo. -- Don_Yacktman@byu.edu Nepotism is a relative thing.

NeXTMail: silbar@cantina.lanl.gov ------------------------------------------------- Dick: Since I have but minimal access to the net, I wonder if you could ask a question for me. Actually two questions, if you feel comfortable doing it. Note: I think the answer to 2 is "You don't, it's a bug", and without the being able to acheive 2 the answer to 1 is useless. Here's what I want to do, and why I would like an answer to the questions. Instance drawing is fast. I can use a buffered window, which is prettier than retained, or non-retained. I can use instance drawing to put just the changing portions of the graphics in the window, ie meter needles etc. for the fastest updates available. Better even than this is if you know what is actually being displayed, and is not hidden then you can instance draw to ONLY the displayed pieces, which is the fastest option I can think of. The problem is that window does not receive the exposed event, and so all this is just a neat theory. I'm also going to report this as a bug. Here are the questions: 1) How do I determine the portion of a window actually, now being displayed on the screen. 2) If I have instance drawing in a hidden window, how do I receive the window-exposed event in a buffered window. NeXT's docs say that I should receive a kit-event of subtype window-exposed. It does not show up at the window windowExposed: method, nor do I believe that the delegate is notified.

Message-ID: <1993Oct13.030251.24378@splunge.uucp> Organization: Ashley, Howland & Wood Date: Wed, 13 Oct 1993 03:02:51 GMT I've got a custom view, grouped in a ScrollView, into which I'm compositing standard icon-sized TIFFs. I'm using NXImages to handle the TIFFs and do the compositing into the custom view. I have set things up so the user may change the viewing scale of ScrollView's contents. I do this by having a popup list call an action method that sets the scale of the ScrollView's docView's superview, i.e. the ScrollView's contentView, a ClipView instance. (Why isn't there an easy way to directly get the contentView of a ScrollView...?) (Since I haven't been able to get ScrollViewDeluxe to work, I'm trying to cobble up my own version of the functionality it has that I want to use.) The scale is being changed properly, but unfortunately, it does not influence the size of the TIFFs composited within the custom view by its drawSelf:: method. I have RTFMed about NXImages, NXImageReps, Views, ClipViews, and ScrollViews, and it doesn't look like there's any direct way for me to scale the TIFFs being composited. So, how does one accomplish this indirectly? TFM says, in regard to NXImage's drawRepresentation:InRect: method, that the method can be overridden in a sub-class, for example to change the drawing scale. I assume this is one way to go, and that if I went this way, I'd have to use DPS directly to change the scale in MyNXImage's drawRepresentation::, prior to calling super's drawRepresentation::. Am I on the right track? Is there a better/different/whatever way? -- Royce Howland Everything is IMHO royce@splunge.uucp (NeXTMail OK) or kakwa!atlantis!splunge!royce

I received the following responses: - A request from Brad Skrbec (skrbec@rtsg.mot.com) to forward whatever I found to him. Here it is, Brad. :~) - A comment from Steve Hayman (shayman@Objectario.com) that he also had trouble using SVD, but managed to get it working by starting with a custom view and changing its class. (This doesn't help me, since I've already got a custom view that I want to group in a SVD.) - A comment from Laurent Daudelin (laurent@planon.qc.ca) that SVD worked succesfully under NS 3.1 black, in two apps, when set up within IB. (This doesn't help, either, since I'm not running 3.1.) - A comment from Jeff Martin (Jeff_Martin@next.com), the author of SVD, that SVD's "group in SVD" is a documented hack, which I knew, that breaks in 3.0 and is flakey in 3.1, which I did not know. He provided some code to disable the group hack, which may help getting things working programmatically (I haven't tried it yet), but partially eliminates the main benefit of using SVD as a pallette. Conclusion: use of SVD within IB can't duplicate the seamlessness of the standard ScrollView, which is too bad. Some or all of the setup of SVD, depending on what you're doing, must instead be done programmatically. It seems at best, one will be able to drag out a SVD instance, and then programmatically replace its docView with one's own custom view. For now, I've decided to stick with the standard ScrollView, and use some of the techniques presented in SVD in a different way, to try to accomplish what I'm after.

I have several textFields connected to a DBModul and set the textDelegate to DBModul. This works fine, when I just enter something into the fields for inserting, updating etc. records. But now I want to give some default settings, which I write into the textFields with the setStringValue method. Now the DBModul won't notice a change of the Cell and therefore won't update the record. I already tried to send messages like TextDidChange to the TextFieldsDelegate (DBModul) but that wasn't working. Any suggestions heartly welcome.

Assuming that the target is implemented following the SCSI specification, the following points are not clear for me: 1- Will NEXTSTEP automatically detect the new device and register it as a /dev/.... device (as it does with a SCSI disk for example). 2- Is there a simple way to communicate with the device with read and write on some file descriptors or should I use the ioctl() function and write new version of read and write ?

Keywords: resizing EPS NXImage Sender: news@news.tudelft.nl (UseNet News System) Organization: Delft University of Technology Date: Thu, 14 Oct 1993 15:21:20 GMT I finally succeeded in reading an EPS file from stdin. The file is displayed in an resizable window. I used the TIFFandEPS program which is avalaible from ftp.next.com MiniExamples, only without using the interface builder like the tiny.m program in Garfinkel and Mahoney. The problem is that Iwant to resize the Image if the window is resized. Garfinkel and Mahoney give on page 474 an example which makes use of the sizeTo:: method in the View class. But.... this doesn't work it only resizes the view but not the EPS image. So I tried to make some changes in the drawSelf method - drawSelf:(NXRect *)rects :(int)rectCount { NXPoint pt = {0.0, 0.0}; NXSize aSize; aSize.width = rects[0].size.width; aSize.height = rects[0].size.height; NXSetColor(NX_COLORWHITE); NXRectFill(rects); [anImage initSize:&aSize]; [anImage setSize:&aSize]; [anImage composite: NX_SOVER fromRect: rects toPoint: &pt]; return self; } Now the image isn't displayed at all. In the main program I have also added the following lines [[view superview] setAutoresizeSubviews: YES]; [view setAutosizing:(NX_WIDTHSIZABLE | NX_HEIGHTSIZABLE)]; these lines only replace the functionality of the command-3 in the interface builder(the string pictures).

I have two ways to do library projects. One - a modification of the NeXT-supplied makefiles, where you create a bundle project, include my standard pre/postamble files, and it builds a library instead. Two - a simple hack to ProjectBuilder such that no NeXT makefiles are modified, you install my hack and one makefile of my creation, and you get Library projects right in PB. The first has been tested in NS3.0 and works fine - the NS3.1 version hasn't been thoroughly tested and is still a bit buggy. The second is NS3.1 only, and is quite solid. The PB hack is a much better way to do this. You should know that this hack is not endorsed or supported by NeXT, although I have been assured by NeXT that it does not violate their software license because I am only describing alterations to files and not offering to distribute actual files. I'll NeXTMail either the modified makefiles or the PB hack to anyone who is interested. In addition, I have it direct from one of the authors of PB that it will support Library projects effective in the release following NS3.2 (either NS3.3 or NS4.0, whichever they call it), so my hack is at best a temporary solution (which is good). >I have anothe rpb too: I have a bundle which implements some >classes inheriting from another ones.

This is done so printer drivers launched by lpd can access the WindowServer to do rendering even if no-one is logged in (and without regard for any PublicWindowServer setting).

Tom. tm31@andrew.cmu.edu Carnegie Mellon University It seems that this would be completely your problem - harshly speaking. The NXBrowser object asks its delegate to provide it with its data to be displayed with the likes of BrowserFillColumn:WithPath: (Or something like that, no docs at hand... :-( ). If you want to expand some hierarchy, you'd have to keep it in a data structure internal to your program. I don't know if the Browser cashes columns it has requested, but I would assume that it does not. For your internal storage, I would recommend subclassing HashTable. Add something that processes paths and returns strings. You can implement arbitrary directed graphs with relativly little effort that way. (And I don't know why no such class is in the distribution!)

In IB on that machine the Font menus _did_ have Larger/Smaller/Heavier/Lighter, and the tags on the menu cells were 3/4/5/6, respectively. For all of you wise guys ;-) who suggested that I look in the PasteUp nibs (duh, do I have a copy of that? *-), I wanted to find the answer in a NeXT-supplied app because 3rd-party apps don't always implement stuff the same way that NeXT documents it. For example, WordPerfect uses an entirely different method than -modifyFont: for the four functions in question. It turns out that PasteUp does it the NeXT way, but I wanted to be sure the tags were the same. Thanx, Michael -- Michael_Pizolato@afs.com NeXTMail accepted

The notable example where the above code fails to work is the SPARC chip, which does fancy passing of variadic arguments in machine registers so that va_list is not just an array. Variadic methods are handled just like variadic functions. performv and forward are loses since they explicitly don't handle variadic functions. If you just want a portable Obj-C way of passing arbitrary amounts of type data from one function to another, you could consider stashing the data in a Storage object or a typed stream. This will, of course, be much slower than bbum's solution above but will be more portable. (The typed stream solution has the added advantage of being byte-order independent if you use distributed objects. Hmm, I must admit I don't know if distributed objects can handle variadic functions. Without knowing the types of the arguments, how do you know how to convert the types for use on the remote machine--especially if one machine doesn't use IEEE floating point?) -ccwf

If anyone wants a nice colorzied look at stack construction under NeXTSTEP on an '040 (3.1), I have one as a result of reviewing my ignorance. I could only find a non-solution to the problem-- that is, use alloca() to grab some memory from the stack, copy the variadic arguments into the alloc'd memory (assuming that one could figure out the length of the variadic array), and then make a call to the next variadic function (with the assumption that the function's frame will sit in such a way as to be contiguous with the alloca'd memory).

Speaking of DO and variadic parameters; not only does one not know the appropriate conversion for most arguments, but there is no way to appropriately find out how to expand structures to the point where they could be passed across the wire (whether the wire is the local cpu or something of a different architecture on the other side of the world).

The RTC Chip (is it really a Real Time Clock?? Mine is a NearlyRTC :-)) in the NeXT (or some of it, see below) has the ability to turn the computer on at a certain time. The time is stored in the RTC and is checked on a regular basis. After booting (in rc.local) or just before shutdown (in /etc/halt) you can set when the NeXT should be powered on next time via the power program mentioned above. The normal way is to set the time via Preferences by hand. Here is a short description of power: Enclosed you find some programs for setting the auto-power-on time automatically under program control without using the Preferences Application. Only some NeXTs with a special version of RTC Chip are able to power themself on at a certain time. If there is a PopUp button in the Startup Preferences (in the Preferences Apllication) with "Startup Device" and "Power", you are one of the lucky. People who don't have this feature don't normally miss it; it's nearly undocumented. cb -- [Christian Baur, Muenchen-Germany | A quick self destruct from the 21st floor] [cbaur@informatik.uni-muenchen.de | A smell of gas through the kitchen door]

Each time I alloate the memory, I am allocating three variables, all of which are floating point variables allocated to a maxIndex of 900,000. Here is the code I use: float * FloatingVector (int n) { float *newarray; if ((newarray=(float *)malloc(n*sizeof(float)))==NULL) { fprintf(stderr,"HumanFactors: No memory to allocate variables\n"); exit(1); } else return newarray; } - allocateVariablesForMaxIndex:(int)maxIndex { ToutSG = FloatingVector(maxIndex); ToutCore = FloatingVector(maxIndex); Qcore = FloatingVector(maxIndex); return self; } - freeVariables { free(ToutSG); free(ToutCore); free(Qcore); return self; } The program works fine after the first three calls to allocate and free, respectively, but on the fourth call, it crashes with the failed on vm_allocate error.

Rather than send the audio data over the SCSI bus and send it through the snddriver (I think this is what CDPlayer.app does), I just want to send commands to the drive and let the sound go through the sound card directly so as not to eat up CPU time. In principle I don't believe there is anything wrong with this. However, herein lies the snag. The mixer function of the PAS card apparently has the default value of the CD-ROM audio volume set to almost 0. So, what I need is some help finding code to control the mixer functions of the PAS card. Has anyone already done this, or can someone at least point me to a possible source?

The "solution" is either to make the package with 3.0 (which i > not possible for NS/FIP), or to manually install the archive, by > concatenating all tar files before extrcating them. The 3.1 Installer "package" script is not the problem. Installer "bom" (bill of materials) files changed from a textual format used in 2.X and 3.0 to a binary IXStoreFile-based format in 3.1. However, in 3.1 there is a bug in IXStoreFile that leaves a file descriptor for the backing file open after the IXStoreFile object is freed. This open fd prevents the ejection of the first floppy disk. Unfortunately this bug was not found until it was too late to fix for 3.1. It is fixed in subsequent releases. As mentioned in the included text above, NeXT recommends that developers use the 3.0 package script *in the case of multi-floppy packages.* The 3.1 package script does work whenever the package will not be distributed as a multi-floppy package. There is a downside to the workaround: m68k/i386 "fat" multi-floppy packages that are generated using the 3.0 package script must be installed fat by the customer since there is insufficient information in the textual bom to allow Installer to "thinstall" such a package. BTW, the 3.0 package script works OK under NS/FIP. On the customer side, the "generate a single on-line package from the floppy packages" technique mentioned above can be used in the unfortunate case where the customer receives a multi-floppy package generated without the workaround.

I basically hacked up Draw to have the zooming feature similar to Diagram!'s (as I think you're trying to do). I basically kept most of Draw's organization and then whenever the view is scaled, you need to manually resize each image. This introduces a problem of rounding errors if you can arbitrarily scale the image as you're scaling the image arbitrarily and a good tiff and end up garbage if you don't do it smartly -- which can be at the expense of vm. I set each image to be scalable (-setScalable:YES) and then when it was time to scale, I got the size (-getSize:), scaled the size appropriately, and then set the size of the image (-setSize:). Viewing 600 dpi, full-page image and any scaling at all sank a 32MB turbo into a pile of silicon, but it worked. A solution for me (way back then) was to pre-calculate the size of the image that needs to be displayed, calculate the region of the image that would fit in that area, copy that region of the image and then scale the copy. This was gobs of math and scrolling was slow, but it kept the system usable.

Newsgroups: comp.sys.next.programmer From: bau@cs.cornell.edu (David Bau) Subject: Simple Question About Views Message-ID: <1993Oct18.223834.25406@cs.cornell.edu> Organization: Cornell Univ. CS Dept, Ithaca NY 14853 Date: Mon, 18 Oct 1993 22:38:34 GMT Hello NEXSTEP Gurus! First, a preemptive question: is there any documentation that gives an overview of the structure and operation of the main classes (View, Window, App?). Garfinkel is useful but does not seem to cover much, and the General Reference talks about the API in great detail without overviewing much of anything. Here's my beginner's puzzle. I wanted a button that disappeared when clicked. (A tiff "credits" screen.) So after putting the tiff in the the button and enlarging it appropriately, I attached the button's target to a method that called [TheButton removeFromSuperview]; [TheSuperView addSubview:TheButton :NX_BELOW relativeTo:nil]; [TheSuperView display]; There was another subview that covered the whole superview, so this operation should have taken the buttonView and pushed it behind everything else, right? Well, it didn't. The button stayed right in front. In fact, if the button started out behind some other things, pushing it brought it up in front. Chagning NX_BELOW to NX_ABOVE and relativeTo: nil to other things had no effect. Finally, I decided it was not a good idea to put it back in at all so I got rid of the addSubView::relativeTo: call, and it works, although I now have a view which is not a subview of anything (is that supposed to be an okay thing?). I bring it back later with addSubView: when I want the button to appear in front again. Why didn't addSubview::relativeTo: push the button back? It works fine when I want to bring something forward. How am I supposed to structure views? Is it legal to have a view not be a subview of anything? How about having a view be the subview of more than one thing? Are these questions discussed anywhere? Maybe here. By the way, anybody who wants my source can have it. It's another BackSpace module that does "Life", but smoother and faster and with more options than before. David bau@cs.cornell.edu

Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. comp.sys.next.hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi.

This is primarily a forum for advanced technical material. The NEXTSTEP programmer FAQs are posted here. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here.

Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. comp.lang.objective-c Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. comp.object Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original comp.sys.next no longer exists--do not attempt to post to it.)

Date: Tue, 19 Oct 1993 16:42:15 GMT When I play a sound during a simple animation, the animation noticeably pauses when the sound starts. The animation then continues smoothly after the sound begins playing. The BoinkOut demo does a lot more graphical stuff in it's animation than in mine and there is no hesitation when playing sounds, so there must be additional programming efficiencies that I need to know about. I've tried using different window types, different sounds, switching the order of drawing and playing the sound, and all sorts of other silly stuff but none have removed the hiccups. I've included a short program below to demonstrate the problem. The program requires a sound file named "Sound.snd". BTW, I'm running 3.1 on a NeXT color machine.

You could use Release 2.1 so that nib files are included in a Mach-O segment. This of course does not prevent programmer types who can extract nib files. This got me curious: Is it still possible to include nib files in __NIB Mach-O segment under 3.x PB/IB? Now, Nibs are directories instead of files.

Doing these two things means that the OpenPanel will always only show folders, and the OK button will always be enabled (with the OK button instance variable set to NULL, the regular OpenPanel code can't disable it). Last thing: override the -ok: method to extract the file path from the Browser.

Message-ID: <SCOTT.93Oct20023434@nic.gac.edu> From: scott@nic.gac.edu (Scott Hess) Date: 20 Oct 93 02:34:34 Distribution: world Organization: Is a sign of weakness This evening while building an app that uses TCP sockets, I was checking to make certain that I'd gotten everything MAB. So, I ran the TickleServices Lipo/Edit Files option on the .app/ wrapper, and Lo!, one of the files _wasn't_! After a rebuild with the file _still_ not coming out fat, I looked more closely and it turned out that the file had m68k and i486 archs - not i386! So, I'm thinking "Well, that's neat." Watch the build go by ... and, yes indeed, all those flags are -arch i386. Not an i486 to be seen. So, I look at the object files, and trace the i486 arch down through the subprojects until I find that it's in Socket.m. Hmm. So, I start commenting out code, and reduced the problem to this: // cc -g -O -Wall -arch m68k -arch i386 -c ack.c // lipo ack.o -info // Architectures in the fat file: ack.o are: m68k i486 #import <libc.h> void main( void) { unsigned i=10; i=htonl( i); } So, there appears to be a bug in htonl() which does automagic promotion to i486. Joy. Now for my question - does this make a difference? Presumably not, because all NeXTSTEP (oops, NEXTSTEP) compliant Intel machines are already supposed to be i486, right? On the other hand, why didn't NeXT use -arch i386 switch with the build tools instead of -arch i486, then? [ie, presumably there's a reason.] [BTW, I ran an egrep through the include files on __asm__, and it looks like the only file which uses __asm__ is <architecture/i386/byte_order.h>.

It depends. You're always taking your chances when you compile on newer versions of the OS. If you make use of any functions that are new in 3.2, then no previous release will run them. If your program uses a function that had a bug fixed for 3.2, that bug will be in previous releases of the app. In other words, it's hard to know.

I don't want to wait until > one sound is played. Well, it depends what you want to have happen. Do you want the sounds to play sequentially? Or do you want the sounds to be mixed in real time? If you want them to play sequentially, then simply register an object as the sound's delegate [soundOne setDelegate:myDelegate]; In the delegate, implement the method: - didPlay:sound; This will tell you when a sound stops playing, and you can play the next one. If you'd like them to just be mixed in real time, you'll have to use the new sound API. Here's a little snipped to get you started: // MySoundController - an object to let you play up to MAX_STREAMS // number of sounds simultaneously #define MAX_STREAMS 10 @interface MySoundController : Object { NXSoundOut *device; NXPlayStream *streamList[MAX_STREAMS]; int currentStream; } - playSound:sound; @end @implementation MySoundController - init { int i; [super init]; /* initialize the streams */ device = [[NXSoundOut alloc] init]; for (i = 0; i < MAX_STREAMS; i++) { streamList[i] = [[NXPlayStream alloc] initOnDevice:device]; if (streamList[i] == nil) { fprintf(stderr,"Splat: error allocating playstreams\n"); return nil; } } currentStream = 0; return self; } - playSound:sound { NXPlayStream *stream; // find an available NXPlayStream stream = streamList[currentStream++]; if (currentStream == MAX_STREAMS) currentStream = 0; // make sure that nothing is playing on it [stream abort:self]; // play the sound through the stream... [stream playBuffer:[sound data] size:[sound dataSize] tag:0 channelCount:[sound channelCount] samplingRate:[sound samplingRate]]; return self; } @end then, in your code just do: -(void)makeNoise { [mySoundController playSound:soundOne]; [mySoundController playSound:soundTwo]; } hope that helps, Erik (note: I just typed this code in... I didn't test it. There might be minor errors, but you get the idea)

[program showing use of the Sound object's -play method deleted] Instead of using the Sound object to play, try using the new soundstream API. In addition to being faster, more flexible, and less buggy, it allows you to mix sounds in real time.

While working on the icons I stayed in 12-bit mode. I thought I understood that the black-and-white dithered 2- and 8-bit images would be created automatically when I saved the 12-bit image. But when I look at the 2- and 8-bit images, some are only partially there and others are completely blank! I opened them in TIFFany to see if it could help me understand the problem, but they look the same there--no additional info. Can somebody tell me what I did wrong and how to fix them without completely re-drawing the icons? I posted about this problem a couple of weeks ago but got no replies.

To prevent this kind of attack, you might attach a cryptographic checksum over the code segments of your executable. However, I'd still be cautious that someone with root access on a workstation could diddle with the memory of the running executable and cause it to crash or not do the unlink. Also, unlink in the shared library might be rendered non-functional by someone with root access to the workstation.

CS Dept, Ithaca NY 14853 Date: Wed, 20 Oct 1993 15:30:53 GMT First, thanks to Alexander Spohr for answering my question about a button dismissing itself as a view; turns out that it cannot do such a thing until the event is finished processing, so it should remove itself using [perform:with:afterDelay:] to do it. Now, a new puzzle. :) I want one of my buttons to perform a continuous action when depressed. I'd like it to behave like the little scroll-bar buttons when depressed: it should send a message to the target immediately, then wait some interval, then begin sending periodic messages. When it is released, it should *not* send a final message. I cannot seem to get this precise behavior by using the setPeriodicDelay:andInterval: message. I can't get the quick initial message or supress the final message on release. Can Buttons or ButtonCells be coaxed into my desired behavior without too much work? After all, NeXT already seems to have such creatures in every scroll bar. David

Are you getting confused between the use of the static keyword in C++ vs. Objective-C? In Objective-C the static keyword has its traditional meaning, that of declaring a _variable_ private and permanent. In C++, an _object_ declared statically will actually cause it to be constructed sometime during program initialization. In Objective-C you cannot declare an _object_ to be static in the C++ sense. Only pointers can be declared static and that doesn't cause an _object_ to be allocated.

We are using the normal array of NeXT's objects, including DBkit. During development and beta testing, we have been using Sybase as the database engine. Our group currently deploys all of it's DBMS efforts in Ingres. Some of our relevant 'enterprise' information is in these Ingres databases, and we have good Ingres support within our group. While Sybase is workable, Ingres offers more to us for this application and has some strategic importance in other areas. As such, we would like to port our NeXT DBkit applications to an Ingres Server engine as soon as possible. We are aware of the DBConnect for Ingres adaptor from Pentultimate: Development (and/or Rathe Inc., depending to whom you talk) and have evaluated it for our purposes. The current release of the Ingres adaptor from penUltimate only runs on the black hardware. Given the fact our client requires Intel support, we have had discussions with penUltimate and it's partners to provide support for Ingres code. Due to pressures within our own project timetable and other factors too lengthy to address here. We are attempting to reevaluate our options in locating/developing technology to address the need for a suitable Ingres adapter. Another option is of course to remain with Sybase as a database engine within this project but that would require significant effort to bridge the Sybase and Ingres repositories here. We are seeking answers from the net to the following questions: Is there another Ingres (version 6.4 compliant) adaptor available or nearly available for NeXTSTEP for Intel? If so, can someone comment on their functionality? Is anybody interested in building an Ingres adaptor? Are you holding back because there is purportedly one on the market? Are you looking for some purchase commitments before undertaking development? Are there other users of penUltimate's Ingres adaptor that are looking for Intel support, or other enhancements to the adaptor? Please email me with the responses... I will summarize and repost if there is enough interest. ------------------------------------------------------ Robert R.

I am wondering what QuickRenderMan is like an if there is a way to have QRM stuff rendered on a certain machine as you can do it with the normal RenderMan. It would be nice to have QRM running on a fast server while working with a normal desktop machine. So combining it with PDO would not require a complete port of NeXTSTEP. So you NeXT gurus out there on the net: Would it be some kind of a simple recompile on the server ? If QRM produces PostScript and does not do the drawing on its own there might be an easy way.

I've used IconBuilder a bit, and I don't believe it will automatically dither your 12-bit image to create a 2-bit one. So unless you painted the 2-bit image as well, it will be blank. Here's a work-around: (1) View your TIFF in 12-bit mode. (2) Do a Select All (cmd-a). (3) Toggle to 2- or 8-bit mode using the pop-up list. (4) Paste the image. By doing an explicit copy and paste, I believe IB will dither the image for you. Of course, since it's dithered, it won't look as nice as a "native" image. Hope that helps. --Ed Lau edlau@cs.princeton.edu

Basically, I'm wondering how easy/hard it would be to port both the application code, and the graphics, to another platform, like Macintosh, or DOS, or whatever. Also, if anyone would care to explain the process of building a NeXT app a little more than described in the literature, feel free to do so.

I am wrote a simple server called Software.app to collect information about software on a network server. You may ftp it from physics.stanford.edu. Several people have told me that there is a bug in it. Specifically, after the client quits there are still connections left to the server. This is bad for security reasons. What is worse is that these connections are also present on the server. So now my server has about 100 connections which I can't disconnect (one can check using netstat command) and it is working very very slowly. I tried to fix that bug for a couple of days but I could not. Then I tried another Distributed Objects application -- RemoteVote in /NextDeveloper/Examples/DistributedObjects. It has the same bug!!! How to test it: Assume you have two NeXT computers foo and bar on local network. Compile RemoteVote on computer foo. Run it. execute command netstat | grep bar on computer foo to see that there are no connections between foo and bar. Then Run RemoteVote on bar. execute the same command again on foo to check that now there are connections between foo and bar. Now quit RemoteVote on bar and check that there still are connections between foo and bar. For more fun, run RemoteVote on other NeXT computers and quit it. Then check that you have a load of connections on foo and it works like a turtle. What can be done? I have not been able to find anything in documentation about disconnecting connections. Has anybody solved this problem? If not I would have to rewrite Software.app using UDP which is a pain in the neck compared to Distributed Objects. Comments greatly appreciated...

Lee did his original PhD work at CMU a couple of years ago; the system was called SPHINX and was developed on first SUNs then NeXTs. After he joined Apple Lee's work at CMU was taken over by VISUS (CMU's commercial arm), and was available as their NeXT product SpeechKit. SpeechKit enabled developers to build speech recognition into their applications, probably with the same vocabulary and accuracy limitations (~1000 words?) as the Apple system. I have changed the above (compiled from a longer couple of messages I sent out a year or so ago) to past tense as there is no mention of SpeechKit in the current Third-Party Products catalogue. VISUS still exist, of course, but I guess that the demise of NeXT's hardware (c/w DSP...) will have hit the speech-recognition side of things rather hard! Try contacting VISUS on: 1-800-36VISUS (412) 488 3600 (412) 488 3611 (fax) info@visus.com anyway... they may still be able to help. Since SpeechKit cost around $10,000 I'm sure they might be persuaded! I hope they may still be devloping something along these lines, which might use some of the M56000 DSP cards promised for Intel.

However, if I run the debugger once and push the button while in debug mode, the button correctly changes its image. If I quit the debugger, the button seems to act correctly. It's like the debugger actually fixed the problem permanently? I am in a total state of confusion. I was 99% done with this program, and now these wierd problems. I didn't really change any code, either! The problems just cropped up when I compiled the code from scratch, after doing a make clean. I have been switching development between a NeXT COmputer at home and an Intel system at school, and I hope these problems are not arising becuase of my use of both Intel and Motorola to do development! Oh, I almost forgot. I DID compile the program once WITHOUT linking the MallocDebug library since I saw no need for further debugging. After I did this, the problems seemed to arise. Is this a bad thing to do? I have since reinstated the Malloc Debug library linking, but this doesn't seem to help. Eric

Just to correct some misinformation. Visus is not CMU's commercial arm. This is one spin-off company from some of the research projects that are ongoing at CMU. There are a small raft of companies here in the area formed after/during successful projects at CMU. Reading the release notes for NS for Intel, it's pretty hard to say that the sound support is anything near stable. So, any live recognition system would have to battle those bugs first before it could become viable. I'm not very interested in battling them for our research demos. If that PA-RISC port gets finished and they support the HP audio hardware reliably, that would be something to see though. ..eric

From: tyen@mundo.eco.utexas.edu (Anthony Yen) Newsgroups: comp.sys.next.programmer Subject: DB on NSi3.x? Date: 22 Oct 1993 07:47:03 GMT Organization: The University of Texas at Austin, Austin, Texas Message-ID: <2a835n$nua@geraldo.cc.utexas.edu> I am looking for any references to database products that will run under NSi3.x so that I can provide a client with a one-workstation solution. Sybase was not terribly helpful, no matter how good the claimed integration with DBKit is; my territory rep says they only plan on supporting Sybase client on NS. Just what does DBKit do that is so hot, anyways? What kind of API is it (low-level, etc.)? And would I be able to write another backend to it without having to get anything above and beyond the Developer Kit? I've heard conflicting reports from other developers about it: some use it, others swear at it. What is net.wisdom? At this point, I'm pretty well ready to cast nearly half of the development effort into porting University Ingres 8.9 (or running Postgres) and rolling my own interface. The literature I have seen to date does not appear to support the notion of running a database server and a client application on the same physical box. Practically the other half of development effort is going to wind up in writing up some report formatting class based on TeX, unless someone has something better to offer than PasteUp. This is ridiculous: from what I've been hearing, lots of people are rolling their own with this kind of stuff (native database and DTP-style report writing), which is what NS was supposed to ameliorate in the first place. Hopefully, I'm totally, completely, wrong. FYI, the project I was tapped for takes in survey results, scores them, and issues reports on the scores that look like they were desktop published (two-column chunks of text, bar graphs, different fonts, line graphics). It stores the results and the text of the report that was fine-tuned by hand for later retrieval. The report is formed out of entirely canned text, all of it tagged at the sentence level with unique codes. The codes are used during production of the report from the scoring formulae. So my database needs are not tremendous; even a flat-file would do. As long as it stays on one box; integration with DBKit would be nice (I like to stick with standards as much as possible, as long as I'm going to take the plunge with a decidedly non-standard---marketshare-wise---system). -- Anthony Yen - SPARC Sysadmin - Department of Economics - UT/Austin ECB 3.138, MS#63100 - 471-3211 ext 170 - tyen@mundo.eco.utexas.edu

Eric, in case you were thinking to yourself, "Nah, that can't be it," think again. ;-) Seriously, this "feature" of debuggers has bit many a programmer. BTW, gdb is not alone in this respect. dbx/debugger on Sun's does the same thing. One of the features of a good compiler is to give you those nifty warnings "xxxx used before initialized", or whatever. I don't do a lot of NeXT development, but under emacs, "M-x compile" and "^X-`" can eliminate those warnings in a snap! ;-) Mark -- Mark Wuest mdw@sitar.jazz.att.com (NeXT Mail Ok)

From: aking@bbn.com (Allen King) Newsgroups: comp.sys.next.programmer Subject: Missing GDB Frame on errors Date: 22 Oct 1993 15:18:34 GMT Organization: Bolt Beranek and Newman Inc., Cambridge MA Distribution: world Message-ID: <mcfueaINN6is@news.bbn.com> The following is an annoying problem with gdb which I bump into many times a day. It seems to have appeared with 3.1, and I hope it'll go away soon (like in 3.2!). Here it is: When you execute some undefined method (such as -hide: in the example below) and get the message "does not recognize selector -hide:", the context that generated the message is nowhere on the stack. This makes tracking non-repeatable bugs VERY DIFFICULT! Consider the following toy example: ------MyView.h: #import <appkit/appkit.h> @interface MyView:View { } - someDefinedMethod; @end ------MyView.m: #import "MyView.h" @implementation MyView - drawSelf :(const NXRect *) rects :(int)cnt { [self someDefinedMethod]; return self; } - someDefinedMethod { id someId = self; [someId hide: self]; // this is a bug! return self; } @end The bug (that -hide: is defined for Application, not MyView) is easy to spot here because the program is so small. Not so in bigger programs. Just plunck the following in a directory, and do the standard things to make an app with PB and IB. Install a custom view of type MyView in the main window, compile, and run with gdb. It will respond with: objc: MyView: does not recognize selector -hide: ... (gdb) where ... #5 0x50354a6 in -[Object doesNotRecognize:] () #6 0x503550c in -[Object forward::] () #7 0x5006c16 in _objc_msgForward () #8 0x4a08 in -[MyView drawSelf::] (self=0xbc810, _cmd=0x6188bfd, rects=0x3ffe904, cnt=1) at MyView.m:6 #9 0x601b5d2 in -[View _display::] () ... There is no frame for -[MyView someDefinedMethod]. It would be between 7 and 8. Have others encountered this? Is there a good reason to have it this way? Again, in this simple program, not a problem, but in bigger programs with unrepeatable bugs, it's a pain. Allen King P.S.: Please email responses to aking@bbn.com and I'll summarize.

Message-ID: <2a6ifa$q33@rosie.next.com> Distributed objects [DO and PDO] connection failing Q: I have client application which is connecting to a server on another machine. When I specify the hostname, the client successfully connects to the server. The problem occurs when I specify the "*" wild card for the hostname. In this instance the connection fails and nil is returned. What might cause this? A: When you specify the hostname, the DO request is efficiently routed as necessary to make the connection. However the wild card search is much slower since each machine on the subnet must be queried. For this reason the wild card search limits itself to the immediate subnet. In other words, the wild card search will fail if the two machines are not on the same subnet causing the two nmserver processes to be unable to find each other. Also see the documentation for +connectToName:onHost:fromZone:. There are a couple possible strategies you can employ to avoid using the wild card when you don't know the hostname: 1) Hardcode a machine name. Of course it would be a friendly gesture to allow this machine name to be changed in the Preferences panel of the Client application. 2) Register the name with netinfo. For example, you might want to create a new directory in the locations directory called myAppNameServer. The myAppNameServer directory would contain a property which lists the value of the hostname where the server is located. Valid for 3.0

At one point in time, a friend of mine and I pursued writing our own kernel-- actually figured out how to get cc/ld to compile and link something that didn't use any libraries. Combine that w/some code that diddles screen memory (though it can't use the "nice" API provided by ioctl() to get the address), and you have starts of a kernel that can actually display stuff on screen (we started by blinking a single pixel on and off).... But, we did all that, and screen stuff was EXTREMELY slow (to non-existant)... Dissassembling the kernel, it seems that NeXT loads micro-code into the DMA controller chips and starts the DMA channels during the boot process... BTW: at what point can one use kgdb to debug a kernel-- it has to be sometime after the serial ports/ether ports are initialized; which is probably too late to catch the interesting low-level hardware init stuff... b.bum -- b.bum <bbum@friday.com> | "blah blah blah" WhiteLight Systems, INC. | - someone somewhere

My questions: 1. Is it possible to create NXApp's Menu and Main window without starting the main event loop (and how). No, you absolutely, positively need to -run: NXApp at least once. The first time NXApp is run it does some only partially known magic and all attempts to bypass it have ultimately failed. However, there is no reason it has to be kept running and you can't -stop: it e.g. in -appDidInit:. After that you have two options. You can either periodically -run: and -stop: NXApp so that NS events get processed in the standard fashion. Or you can just run NXGetOrPeekEvent/DPSGetEvent/... and handle the events explicitly yourself (not forgetting to set the running instance variable of NXApp). As there is some more magic done in the run loop generally the former method is perferable. 2. If the answer of the first question is YES (I hope so), how can I get MOUSEDOWN, MOUSEUP and MOUSEDRAGED events? See above. In the first method you'll get them in your views methods. In the second one, you'll have to interpret the events by hand. 3. The original program is terminal driven.

I've got a situation in which using DBModeler to change the properties of a database model is just too time-consuming to do manually, so I've written a process that opens each nib and changes the model based on info captured in each nib. Problem is, I'm unarchiving over 400 nibs with swapfile growth of over 60 MB! So I'd like to free the memory allocated when each nib is unarchived before unarchiving the next nib. I thought that I'd unarchive each nib into a new memory zone and then destroy the zone when I've gotten the info I need. I've got lots of custom non-view objects in these nibs in addition to one or more windows and panels, so destroying the zone seemed like the most straightforward approach to reclaiming memory. However, when I implemented this simple-minded approach, memory access violations crashed my app. So I figured that I really needed to free all windows and panels so that associated window server resources could be freed before destroying the memory zone. Bzzzzzt!! Nice try, thanks for playing, but no cigar. Similar crashes occur along with another one that occurs because "TextField does not respond to realObject". Say, what? I'm not sending that message in my code, so I guess that's a private method. I've also noticed that unarchiving my first nib also seems to instantiate several shared system panels like the Spelling panel, so freeing these doesn't seem like such a good idea. I tried to ignore these panels, but maybe I'm still missing one or more and am inadvertently freeing them. So if anyone has the magic key to freeing memory after a nib is no longer needed, please let me know. I'll summarize for all to enjoy. -- Art Isbell Cubic Solutions NeXT Registered Developer NEXTSTEP software development and consulting NeXTmail: art@cubicsol.com Voice: +1 408 335 1154 USmail: 95018-9442 Fax: +1 408 335 2515

Submissions should be e-mailed to next-announce@digifix.com where the moderator (Scott Anguish) will screen them for suitability. comp.sys.next.bugs A place to report verifiable bugs in NeXT-supplied software. Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. comp.sys.next.hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. comp.sys.next.marketplace NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. comp.sys.next.misc For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! comp.sys.next.programmer Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. The NEXTSTEP programmer FAQs are posted here. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. comp.sys.next.software This is a place to talk about [third party] software products that run on NEXTSTEP systems. comp.sys.next.sysadmin Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. related Newsgroups comp.soft-sys.nextstep Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. comp.lang.objective-c Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. comp.object Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original comp.sys.next no longer exists--do not attempt to post to it.) Exception to the crossposting restrictions: announcements of usenet RFDs or CFVs, when made by the news.announce.newgroups moderator, may be simultaneously crossposted to all c.s.n.* newsgroups. --------------------------------------------------------------------- Thanks to Michael Ross at antigone.com, the main NEXTSTEP groups are now available as a mailing list digest as well. next-nextstep-d next-advocacy-d next-announce-d next-bugs-d next-hardware-d next-marketplace-d next-misc-d next-programmer-d next-software-d next-sysadmin-d (For a full description, send mail saying LISTS to <digestif@antigone.com>).

If any developer was so stupid to a) do registration intercepts at the connector level or b) embed passwords, etc. as readable ASCII in NIBs they deserve all they get. >Yup, flat files are cool -- they save vm, help apps load quickly, separate >unrelated glob of stuff from each other but also introduce problems that >may be worse than the problems they initially intended to solve.

What paranoia? Get a clue: the purpose of compiling source code is merely to convert it into a form that can be executed more efficiently on a given processor. It's not to disguise its intent, function, or operation. Any "security through obscurity" enjoyed on Black Hardware was lost when NeXT decided to support the i486. Software to convert Intel binaries to understandable, editable "C" source code has been commercially available for several years, and some products are quite inexpensive.

I've been using it for months as my primary editor without crashes or other problems. I'm even posting this from a GNUS running in its own emacs window. The reason it is not on the archives yet is that the Free Software Foundation and Richard Stallman consider our NeXT port a nuisance at best and have refused to accept our code.

Message-ID: <1993Oct26.174404.6180@beech.csis.gvsu.edu> Sender: news@beech.csis.gvsu.edu Organization: Grand Valley State University, Allendale MI Date: Tue, 26 Oct 1993 17:44:04 GMT Hello: (Forgive me is this is irrelavant to this group; I wasn't sure which to post to) We have a NeXTStation running as a server for a time-card punching control system. In addition to reading from the magnetic card reader and displaying to a terminal the user's "punch status" (which it is currently doing fine), it should be sounding a signal for the workers at punch-in and punch-out times. We currently have an old XT with our PA system wired to the speaker and a simple program to make the sounds. Obviously, we would like to eliminate the need for this machine, but haven't figured out how yet. The problem with using the NeXT (which, even though it is a server, get's fairly frequently) is that in addition to the scheduled "beeps", all the other sounds come through the system. We tried having the users set their defaults to "mute" out sounds, but then the desired punch beeps don't go through either. I thought I had a solution by making a little script to go through at the right time and "dwrite" the sound "on", make the sound, and then "dwrite" the sound back off again. But it doesn't work. Of course, this is dependant on who is logged in (which in itself could be worked around) - but even with the correct scripting it didn't work. dread shows that the sound is turned on, but still no sound. So, the question is: is there any way to achieve our desired effect, or are we just plain out of luck? It seems ridiculous to me to have to run another machine to do this. Any help would be greatly appreciated. - Jim wissner@beech.csis.gvsu.edu

Make source available (since that's the GNU way :-), and add a note saying that you will not be able to actively support it in parallel to the standard moving-target GNU releases. Who knows? Get enough people using the NS Emacs version and there's no telling what can happen -- maybe someone else can pick up the support of it. Stephen Peters

Here's the README: ------------------------------------------------------------------ Alpha Release of the Collection Library for GNU Objective-C WARNING: This library is still in alpha release, and has not been thoroughly tested. I am making it public now in order to get feedback on design issues. A further warning: The API may still change before the first official release---if you write code based on this library you may later have to update your code to match. ------------------------------------------------------------------ * Where can you get it? How can you compile it? By anonymous ftp at cs.rochester.edu:pub/libcoll/libcoll-yymmdd.tar.gz where yymmdd is some string of numbers specifying its date. The library requires gcc 2.5.0 or higher. See the INSTALL file for more instructions. ------------------------------------------------------------------ * What is the Collection library? It's a library of Objective-C objects with similar functionality to Smalltalk's Collection objects. It includes: Set, Bag, Array, CircularArray, GapArray, Queue, Stack, Heap, LinkedList, BinaryTree, SplayTree, RBTree, Dictionary, MappedCollector, EltNodeCollector and DelegateList. Outside of its main heirarchy it also includes List, HashTable and Storage objects compatible with NeXT's objects of the same name. This release also includes a very preliminary version of a String object. I threw it together mostly as a thought-experiment to make sure that my changes to the IndexedCollection abstract superclass would fit well with a String class. Many methods are left unimplemented; it is not useable. As an extra plus, the .tar file includes classes Magnitude and Time. Eventually the .h files for these will be moved outside of the "coll" directory. Here is the object inheritance heirarchy. All protocols end with "ing"; all collection protocols end with "Collecting". All collection abtract superclasses (classes which are not usable without subclassing) end with "Collection"; Collection <Collecting> Set Bag KeyedCollection <KeyedCollecting> Dictionary MappedCollector IndexedCollection <IndexedCollecting> Array Stack GapArray CircularArray Queue Heap LinkedList BinaryTree RBTree EltNodeCollector String DelegateList LinkedListNode LinkedListEltNode BinaryTreeNode BinaryTreeEltNode RBTreeNode RBTreeEltNode HashTable List Storage ------------------------------------------------------------------ * What's new in this release? - Installation using ./configure and autoconf - New BinaryTree and RBTree(unfinished) classes. Rewritten LinkedList class. - A new scheme for holding non-object elements in classes that require object contents; EltNodeCollector class. - Archiving with -write: and -read: methods. This involved removing the ability to set the comparison function independent of content type. - Removed COLL_NO_ELEMENT and friends. Now there are no arbitrary restrictions on which long int's can be stored. Like in Smalltalk, ...ifAbsentCall: methods have been added to replace this functionalty. - Added a LABMDA() macro for defining small functions in the arg position. - Removed many ...perform: methods. Use instead the more flexible ...call: methods with LABMDA(). - Renamed ...Description: methods to ...Encoding: for better use of already-defined objc keyword: @encode(). - New in the Collecting protocol: + Filtered enumerating instead of filtered shallowCopy'ing. + Enumerations still safe when modifying the contents. - The beginnings of documentation in libcoll.texi. - Many bug fixes. ..and more. See also the ChangeLog for notes about the differences between this release and the last. ------------------------------------------------------------------ * How can you help? - Read the questions in TODO. If you have any useful comments mail them to me! - Give me feedback! Tell me what you like, tell me what you think could be better. Send me bug reports. - Donate classes. If you write classes that fit in the libcoll framework, I'd be happy to include them. ------------------------------------------------------------------ R.

If this file were deleted, your machine would have absolutely no way to recover, and it would promptly die at the next physical VM access. Anything you were doing at that point loses irrevocably. Your specific setup, which has the swapfile.front as a special mountpoint, uses the compressed swapping feature. (BTW, this was why you couldn't delete swapfile.front.) The file grows with time as a function of the VM activities on your system. It is an operating system misfeature (not a bug, per se) that the swapfile does not shrink. However, you can reboot your machine to reset the size of the swapfile down to the default of 16Mb. -Chuck Charles William Swiger -- CMU...*crunch*! | 1.

Playa del Rey, CA Date: Tue, 26 Oct 1993 22:59:02 GMT The recent little micro-thread about playing several sounds simultaneously made me dig out the Sound documentation and browse through it. My basic question is about the data. The standard encoding method is 8_BIT_MULAW (I think). There is also 8 bit linear and others. How does one manipulate this data? What IS this data? Is there a text or something somewhere that can tell me the basics of what can be done with this data? Decriptions of what MULAW is? How about mixing two sounds together -- just add them up? Anyway, I'm just looking for some basic concepts regarding what the data in a sound file is and what can be done to it. Any hints would be appreciated. Thanx, Will

Actually it's a polygon rendering system for a computer graphics class. The SGI graphics calls are well localized, and all the rest of the C++ compiles and works on my Next. I now want to hack together a viewer to look at all my rendered polygons on the NeXT. But to avoid duplicating a lot of work this means I have to mix the C++ and obj-C pretty freely. Can I do this? Questions that occur to me are very basic - should the file be .m or .C? Can I say [myView doSomthin]; in one breath and polygon.apply_matrix(M); in the next. Can I send objective-C messages from within C++ class member functions? (So I can define a NeXTy version of polygon.draw_in_view(id theView)); Any help - particularly example programs (the simpler the better) - would be greatly appreciated.

See the documentation for DBEntities: The DBEntities protocol incorporates the DBTypes protocol. It does this for one reason: the type of Objective C data described by a property that represents a relationship is a DBEntities object. Thus, if the isEntity message returns YES when sent to the value returned by sending propertyType to a property, then that property is a relationship. This is demonstrated in the following example: /* Get the properties from an entity. Check for relationships. */ int counter; List *propList = [[List alloc] init]; id prop; [anEntity getProperties:propList]; for (counter = 0; counter < [aList count]; counter++) { prop=[aList objectAt:counter]; if ([[prop propertyType] isEntity]) printf("Property named %s is a relationship.\n", [prop name]); } Atze -- Alexander Spohr, Hamburg, Germany Alexander_Spohr@dART.de (Mail ) Faces and faces (+49) 40 / 380 23-0 (Sound) See them and complain not

We are having a quite hard time trying to use MallocDebug with our Program. The problem: Our program is modular, so we are using runtime loading, with source code to the modules spreaded all over the country. For this reason i have to use the -all_load flag, so that all library functions get loaded into the initial program. In an attempt to debug some memory problem, i tried to link the MallocDebug Library to our code. That ends up in a lot of multiple defined symbols, so i added the -m flag to the linker flags. But this leads to the following message: ld: Can't open: -L/lib/m68k for -sectcreate -lcrt0.o -L/lib/m68k (No such file or directory, errno = 2) Here are my questions: 1. Is there any way to get the MallocDebug Library linked to our code and still using the -all_load flag? (Collecting all the .o-Files and forgetting about the -all_load is quite out of the question) 2. If there is (hopefully) a positive answer to 1, this might also enable us to use the Profile Libraries. But is there any way to do profiling on any runtime loaded code? Please answer to my E-Mail address, i will summarize. Thanks in advance!!!

Probably the easier approach would be to supply an alternate loginwindow app and then use that in the /etc/ttys file to run instead of loginwindow.app. I have no idea if this would work, but NeXT uses a class called LoginView in the loginwindow.app so I would suspect you could subclass it and just override the login: method to do whatever you want your authentication to be.

I have been using a system written and interpreted in Scheme; I'm expecting about a 1000-fold speed-up by converting the core signal processing to DSP assembly language. I have Motorola's DSP User's Manual, and the Assembler Manual is online. Where I'm having trouble is putting all the pieces together on the NEXTSTEP side of things. I've been reading a documentation set (NS 1.0 I believe, but maybe 2.0, I can't tell) and I've been looking through some of the examples I've found on ccrma.stanford.edu. I have a few queries: 1) What is the best set of documentation (from NeXT or elsewhere) for using the snddriver kit. I expect the 2.0 docs are it, right? Or is there more advanced stuff at CCRMA (which incidentally is refusing anonymous FTP logins today) or elsewhere. Anyone have a complete set of NeXT's 2.0 or 2.1 developer docs they'd like to sell? 2) Also, some documentation I've found refers to the Release Notes for 2.x, saying they have lots of good stuff on the DSP. Are these available online? I believe I have a license to use them since my system came with 2.1 when I bought it. I upgraded before I contemplated any development work.... (NeXTmail ok!) 3) Which are the best archives with examples of the gory details involved in CODEC input and double-buffered DMA transfer output with the DSP. 4) Specifically, how does one set up streams so that the DSP grabs (is given?) samples directly from the CODEC, does some processing, and ships the results to the application via DMA. The application needs to receive a new buffer of DSP outputs every 50 - 100 milliseconds for real-time display of the results. I believe what I want to do is similar to the MonsterScope application when it's running in spectral-analysis mode with MIC input. Anyone got sources they'd let me look at that use the DSP for real-time processing of CODEC input with DMA back to the application. My documentation doesn't mention the DSP getting its input directly from the CODEC, but the Laroche examples from CCRMA state that it's possible. How's it done? Also, none of the examples I've seen so far discuss getting small chunks of data back to the application via DMA, they all set up a big transfer and wait for it to complete. I think most of my confusion stems from not understanding what the DSP had to do in order to interact correctly with the snddriver. In particular, does anyone have a description of what interupts etc the DSP must service, and what registers it must use to interface correctly with the snddriver? 5) Where do I get extra DSP RAM? Anyone want to sell me the appropriate 96 KB SIMM (24 k-words of 3 bytes each)? Hey, thanks in advance for any documentation, help, advice, pointers, code, RAM, etc you can make available to me.

From: zmonster@ATHENA.MIT.EDU (Eric M Hermanson) Newsgroups: comp.sys.next.programmer Subject: Help me disable a slider while it is being moved! Date: 28 Oct 1993 23:56:50 GMT Organization: Massachvsetts Institvte of Technology Distribution: world Message-ID: <2apm82$o1a@senator-bedfellow.MIT.EDU> In my program there is a DPSTimedEntry that calls a method every 0.1 seconds which checks to see if a slider should be disabled. The timed entry has a threshold priority of 12, 2 higher than the MODALRESPTHRESHOLD so that the timer will run even though the mouse is being moved. The problem is, if the timer function sees that the mouse should be disabled, it will send a setEnabled:NO message to that slider. However, IF the slider is being moved or dragged at that time, the message still gets sent, but the slider does not disable. So, I tried sending a MOUSEUP event to the queue BEFORE disabling the slider using DPSPostEvent but it didn't work. The wierd thing is, the MOUSEUP event DID cause the mouse to stop controlling the slider (i.e. it did work), BUT, the slider did NOT disable. So then I tried to remove all mouseup and mousedragged events from the event queue before calling slider disable routine, using DPSDiscardEvents(). But this didn't work either. So far, the only way I can get this to work is by disabling the slider before EVERY timer event is called, then check to see if the slider should be disabled. If so, I leave it disabled. If it is not supposed to be disabled, I enable it again using -setEnabled:YES. This works, like I said, but it is VERY SLOW. The setEnabled call really bogs down the system for some reason (I verified this because the setEnabled:NO call alone does not cause a system slowdown, only the two calls together cause the slow down). SO, the question is simple: How do I override a slider modal loop while the slider is being moved by the user, so that the slider can be successfully disabled? Thanks for the help, Eric

(Sigh.) I would love to see a version of Lucid Emacs that worked with a window system other than X; while redesigning the event loop, we always tried to keep window system independence in mind. (And tried not to make this mean "pretend all window systems are really just fancy dumb-ttys.")

It could be called "example patch for emacs 19.19 NS". If a Readme states clearly, that these patches are NOT SUPPORTED and NO QUESTIONS are answered, I can't see any problem for you. Of course this should be placed on the NeXTSTEP archives, not the FSF archives. If RMS doesn't want this in the emacs distribution, ok! It's his choice, but I *do* believe, that there will be a race for creating new patches whenever a new version of emacs is released by FSF. Look at the development of Linux. There is no need for a regular maintainance. This would be nice, but try without it now! Give the community of NeXTSTEP programmers a chance. Anything that helps other people *today*, should be given to the community, even if RMS doesn't want this. I would love to see it. Ciao, Stephan -- trebels@theo-phys.gwdg.de

Should I just disable it (easy) or recursively disable all its non-submenus menu cells? My user-interface lectures told me to only disable non-submenus items, because the user should be able to see all the potential actions even if some of them are not enabled (that's what make Services menus so annoying some time...). I think it's right, but how can one implement this properly? Of course, sending a setEnabled:FALSE to the menu cell does not work: should I consider that this is what the standard style is intended to do? Or is it just a flaw in the system? (The guidelines does not cover the case of submenus when discussing disabled commands). If the non-submenu case is the right one, did anybody implement it? I do not see any obvious way of doing that, except getting the cell's target (which is a menu), and recursively iterating on its itemList testing for hasSubmenu on the cells. Is there a shorter way to do that?

The problem isn't so much with speed of filling DBTableView (in my case) becuase I actually swap views from a Matrix to a DBTableView which I programmatically pre-wiire to the same fetchGroup which is connected to the Matrix. In my case, it takes a *long* time to execute, say [recordList fetchAllRecords:nil] -- it seems to take an inordinate amount of time to stuff the DBRecordList.

First of all, to do what ping(1) does, you need to be superuser. That's why /usr/etc/ping runs set-uid root. The next best thing (which doesn't require privileges) is to try to bounce something off a UDP echo server. This assumes that inetd is running on the target machine, and the system administrator hasn't done something stupid like disable the UDP echo server. The biggest problem with both of the above is that a nonresponse doesn't necessarily mean a machine is down or unreachable. One easy way to improve upon UDP is to use RPC, as illustrated in the attached example. Note that in Objective-C programs based on the AppKit, you probably don't want to use something like this [that blocks], but rather some combination of DPSAddFD(), DPSAddTimedEntry(), - perform:with:afterDelay:cancelPrevious:, etc. -=EPS=- ------- #ifdef NX_COMPILER_RELEASE_3_0 #include <ansi/stdio.h> #include <bsd/netdb.h> #include <bsd/sys/socket.h> #include <bsd/netinet/in.h> #include <bsd/rpc/rpc.h> #include <bsd/rpc/pmap_prot.h> #else #include <stdio.h> #include <netdb.h> #include <sys/socket.h> #include <netinet/in.h> #include <rpc/rpc.h> #include <rpc/pmap_prot.h> #endif main(argc, argv) int argc; char *argv[]; { void try(); register int i; int errs; struct sockaddr_in sin; (void)setlinebuf(stderr); if (argc<2) { (void)fprintf(stderr, "Usage: %s host ...\n", *argv); exit(1); } errs=0; for (i=1;i<argc;i++) { bzero((char *)&sin, sizeof sin); sin.sin_addr.s_addr=inet_addr(argv[i]); if (sin.sin_addr.s_addr!=0xffffffff|| !strcmp(argv[i], "255.255.255.255")) { sin.sin_family=AF_INET; sin.sin_port=htons(PMAPPORT); try(&sin, argv[i]); } else { register struct hostent *h; register int j; if (!(h=gethostbyname(argv[i]))) { herror(argv[i]); (void)fflush(stderr); errs++; } else { sin.sin_family=h->h_addrtype; sin.sin_port=htons(PMAPPORT); j=0; do { bcopy(h->h_addr_list[j], (char *)&sin.sin_addr, h->h_length); try(&sin, argv[i]); } while (h->h_addr_list[++j]); } } } exit(errs); } void try(sin, target) struct sockaddr_in *sin; char *target; { register CLIENT *c; int sock; struct timeval tv; tv.tv_sec=5; /* RETRY_TIMEOUT */ tv.tv_usec=0; sock= RPC_ANYSOCK; if (!(c=clntudp_create(sin, PMAPPROG, PMAPVERS, tv, &sock))) clnt_pcreateerror(target); else { register enum clnt_stat e; tv.tv_sec=20; /* TIMEOUT */ (void)fprintf(stderr, "Trying [%s]...

Date: Fri, 29 Oct 1993 20:47:20 GMT I want to replace the column titles in a DBTableView with something a bit more substantial, including a small icon for some of the columns. There is a columnClip outlet in the DBTableView class which provides a view of the column title area. But it seems that the proper interface is on a column-by-column basis where the actual column titles draw themselves. Does anybody have a clue how I could accomplish this? I assumed I would subclass some ColumnTitle class which draws in the title view but apparently that is not how its done. Thanks, Jon Rosen

I'm developing an application where I'd like to have the volume set at a certain level during the entire time the application is active. I know that I can use the [Sound setVolume::] method or the setGainLeft:right: method in NXPlayStream to set the volume right before the sounds are played. However, the sounds are of long enough duration that the user could increase or decrease the volume as the sound was being played - an undesirable action. Is there a dwrite parameter similar to -PowerOffDisabled? I haven't seen any documentation on one. The Monitor.preferences bundle in Preferences.app somehow reads and sets the volume control, so there must be a way to communicate with the volume control keys through an application. I've looked in the Monitor.preferences bundle, but there aren't any hints there. Thanks in advance. Mike Blommer

There is another difference between NeXTSTEp and VMS that might make it ok to support VMS but not NS. VMS is an old crusty os that is used only because it has been for a long time. By supporting VMS it is possible to move their users over to GNU a piece at a time. The VMS users that use emacs and gcc don't want to use VMS. It is forced on them by the administration. al.

An NXBrowser seems like a good candidate for the job. However, the non-leaf nodes of my tree can have only 2 string values, "and" and "or", which means that both children of a particular node can have the same string value. NXBrowser's setPath: and browser:selectCell:inColumn seem to depend on each browsercell in a particular column having unique string values. I need to be able to navigate through my tree object based on a user's browser selection, but this doesn't appear to be possible if string values of browsercells are used to construct and set the browser path. I've considered implementing an NXBrowserCell subclass that has an ivar pointing to the tree node that it represents. But before doing any extra work, can NXBrowser and NXBrowserCell be used to implement a binary tree browser as is? Am I missing understanding something obvious? (Probably - we're talking NXBrowsers here :-) Does anyone know of an example of a binary tree browser anywhere? Anyone have any comments, suggestions, etc.?

Furthermore, they don't vanish either as they should. Maybe it has something to do with a #define in conf.h of the zsh which is /* default prefix for temporary files */ #define DEFTMPPREFIX "/tmp/zsh" but I don't know. It seems that this errors don't do any harm, since the resulting library in lib1 works without errors as I've seen so far.

I'm using DBKit with Sybase in an app that has no user interface. It periodically does a select on a table and processes what it finds and updates the successfully processed rows. If I place a break in gdb after the initial SELECT and before the saveModifications, I can, using another utility select the same row, change the data and update the row. When I continue the app under gdb it goes into saveModifications, does a SELECT with a HOLDLOCK comparing only the primary key (a single column) in the WHERE clause, then it issues an UPDATE. There are no errors or warnings and it IS possible to overwrite the modifications of another user if both apps are update the same columns. If there were a comparison of the timestamps, or a column by column compare I would be able to pick up the fact that the row had been modified since the time it was originally read. NeXT's DBKit release notes state: DBRecordList supports multi-user concurrency through a check-before-update strategy, also known as optimistic locking. So, I have a couple of questions, 1). What does the "check" in optimistic locking consist of 2). Does one need a DBModule in order to have optimistic locking 3). Why the heck can't I get a timestamp out of a DBValue (it would fit nicely in a long int and I just want the 64 bits) 4). Why doesn't/can't DBKit support the Sybase FOR BROWSE mode with timestamp checking.

We are having a quite hard time trying to use MallocDebug with our Program. The problem: Our program is modular, so we are using runtime loading, with source code to the modules spreaded all over the country. For this reason i have to use the -all_load flag, so that all library functions get loaded into the initial program. In an attempt to debug some memory problem, i tried to link the MallocDebug Library to our code. That ends up in a lot of multiple defined symbols, so i added the -m flag to the linker flags. But this leads to the following message: ld: Can't open: -L/lib/m68k for -sectcreate -lcrt0.o -L/lib/m68k (No such file or directory, errno = 2) Here are my questions: 1. Is there any way to get the MallocDebug Library linked to our code and still using the -all_load flag? (Collecting all the .o-Files and forgetting about the -all_load is quite out of the question) 2. If there is (hopefully) a positive answer to 1, this might also enable us to use the Profile Libraries. But is there any way to do profiling on any runtime loaded code? Please answer to my E-Mail address, i will summarize. Thanks in advance!!!

The floppy device only has one parti- tion per disk. For example, /dev/fd1a refers to unit 1. Similarly, a character device is accessed by /dev/rfd<unit><partition> where <partition> is either ``a'' or ``b.'' Partition b of the character device, such as fd0b, is a special device called the live partition. I/O to/from the live partition is used to access disks that do not have a valid label, and to access portions of disks normally inaccessible to the read() and write() calls - for example, the front porch. (Reading and writing the ``a'' partition of the character or block device requires a valid label on the disk.) I/O using the live partition has the following restrictions: + Reads and writes must start on a sector boundary. + The length of reads and writes must be an integral multi- ple of the sector size. -Chuck Charles William Swiger -- CMU...*crunch*! | 1.

Technologies Distribution: na Date: Tue, 2 Nov 1993 19:11:55 GMT Has anyone had any success using a terminal connected to a serial port under NS/FIP? We have no problems using a Wyse 160 in vt100 emulation mode connecting to NS/FIP via a DEC terminal server, but when we try to connect via the serial port we see some weird behaviour. The fourth character in a line is frequently dropped, and the driver wants to map the F1 function key to the NULL character. We can probably deal with the latter problem via termcap changes, but the dropped characters are a concern. More details on the setup: - Wyse 160 in vt100 emulation mode - 19200 baud, 8 bits, no parity - modified /etc/gettytab so that the std.19200 entry reads g|std.19200|19200-baud:\ :sp#19200:p8:ap: - set up getty in /etc/ttys as ttyb "/usr/etc/getty std.19200" vt100 on secure - serial cable only has TX, RX and GND connected We tried reducing the baud rate to 9600, but characters were still being dropped. Any suggestions are welcome. I would prefer to rely on software flow control if possible, but I can connect the hardware flow control lines if necessary. I should point out that we had no trouble getting 19200 baud connections over a 3 wire cable under SVR4. - harv -- Harvey C. Dueck A.L.I.

Any help would be > appreciated!! Although make doesn't have the magic switch you are looking for, you don't have to enumerate each dependency yourself either - let gcc do it for you! Try the -M switch to gcc (excerpt from the manual): -M Produce a rule suitable for make describing the dependencies of the main source file, instead of outputting the result of preprocessing. The preprocessor produces one make rule containing the object file anme for that source file, a colon, and the names of all the included files. If there are many included files, then the rule is split into several lines using backslash-newline. Try: cc -M *.c *.m and add the output to your makefile.

It does NOT play the audio stuff through your soundcard, this would (as you mentioned) eat up your CPU cycles. It just uses the CD ROM commands to play sound OVER THE HEADPHONE JACK on your CD ROM. So you will hear nothing without connecting a pair of headphones to your CD ROM. NEXTSTEP has nothing to do with the audio playing of a Music CD. By the way: if you try to send 44KHz-stereo-data over an ISA-Bus you will have no chance to succeed. It simply is to slow. I have a Toshiba 3401 too and it just works.

E-mail would be appreciated. > - Eskandar If you call -init you are talking to an already established object. A +new has to set the ivars somehow. But how are you going to do this? The only way (if you don't use a private -init) is to have public ivars... urgh! The other thing is that you don't litter your objects with class methods if you subclass. The FontPanel and PageLayout (and Open- / SavePanel) are unique to an application. So your programm should not alloc a new instance every time, but ask the class object (which is unique to every application as well) for the actual instance (creating one if there is no such).

Any advantages/disadvanatges? [some deleted] The general idea seems to be that if you have a class (Foo) that is intended to be instantiated multiple times during the run of a program, you use [[Foo alloc] init], and if you have a class that intantiates once and prevents multiple instantiations you used [Foo new]. The new method generally checks for the existence of the single instance, and if it exists simply returns it. If it does not exist, the new method creates it and then returns it. This is why you say [FontPanel new] but [[Button alloc] initFrame:&frameRect]. You almost always have more than one button in an app, but only one font panel. The FontPanel class will give you the id of the single instance of the panel every time you run the "new" method. Of course, it seems contradictory to call the method "new" and not to have it return a new instance. But this usage seems to be the way NeXT has gone, and we have also taken to doing it this way internally here at AFS. In addition, unless you want to create methods like -new:(NXRect*)frameRect, or invoke new and follow it by setting attributes, the alloc/init technique is the only way to initialize anything properly whose designated initializer is more complex than just "init". Hope this helps. Thanx, Michael -- Michael_Pizolato@afs.com NeXTMail accepted w] but [[Button alloc] initFrame:&frameRect].

In C++ "new" is a keyword/operator. > They replaces new with alloc init, so that people could write Objective > C++. I don't beleive this is the answer. There were several reasons for the change. I know that one of them was the fact that the number one cause of bugs in programs during the 0.9-1.0 timeframe was incorrect instance iniliaization inside the +new method. It seems that many folks would setup the instance vars for a new object inside the factory new method. This just doesn't work and can cause real problems. (I think due to the lack of class vars space). Folks then had to build a -initialize method to do setups. Anyway, it was decided that breaking out the memory allocation (factory) and the instance initialization (instance) would help cut the ramp up time for new programmers. The +new method was retained for classes that returned shared instances, ie: classes that don't alloc a new one each time. Thus, the shared SavePanel and shared OpenPanel have +new or derivative methods. -- Joe Freeman FreemanSoft Inc. A NEXTSTEP software and consulting services company.

The headers are not where the routine looks for them. Thus they are not fixed and gcc is not built correctly. I am not sure if this is a FSF problem or if NeXTSTEP 3.1 moved and/or broke the headers. Anyway the routine has to be changed or you get an internal error in gcc. cc++ works just fine. If you install gcc2.5.2 then delete the headers in /usr/local/lib/gcc-lib/m68k-next-mach/2.5.2 and replace them with an old set from /usr/local/lib/gcc-lib/m68k-next-mach/2.4.5 by just renaming 2.4.5 to 2.5.2 then gcc and g++ will work.

I don't believe this and it doesn't even make sense. The compiler/parser is smart enough to know the context in which "new" is used inorder to determine whether it is a valid operator. I believe that without +new you dont' have to fart around with assigning to self ie. self = [super new] and it just formally ensures that initialization is separate from allocation this way.

This works fine for backspace, delete and command-x. The problem occurs if the user chooses Cut from the menu. cut: invokes textDidGetKeys: isEmpty: but there is no charCode since no keys were depressed. I can't just assume that all null charCodes are Cut, since I also want to trap Paste and Delete. > > Does anyone know a way to ask the application "who" invoked the method? One solution is to determine whether the coordinates of the mouse down (of the current event) lie in the rect of the Cut menu cell, but I was hoping for a cleaner solution.

Newsgroups: comp.sys.next.programmer From: bbum@friday.com Subject: CrashCatcher (was: GDB & Lost Frames) Message-ID: <CG1xJG.1Kn@friday.com> Sender: bbum@friday.com (Bill Bumgarner) Organization: Friday Software & Consulting; a virtual company Date: Sat, 6 Nov 1993 03:54:51 GMT Be forewarned, this is kind of a plug for a potential product. I ran across the lost frame bug in gdb quite a number of times-- a most annoying non-feature. It turns out that the frame information is available, but gdb is decoding things the wrong way. Which brings us to the plug. For WhiteLight, I have written a package of technology called CrashCatcher. It is a self-contained unit of code that was originally intended to provide diagnostic information whenever an application crashes on-site (and automatically email a crash-report back to the parent company). As the project evolved, it became clear that CrashCatcher provided a large quantity of more accurate information than what was provided by gdb. This includes NOT skipping a frame when an application dies from an objective-c runtime error. Once CrashCatcher became an integral part of the debugging environment, it became justifiable for me to spend more time in augmenting CrashCatcher's feature set. At this point, CrashCatcher provides quite a number of features that aid in the debugging of an application. Whenever an application crashes (or enters a detectable failure state), CrashCatcher generates a report of the state of the application. This state report is dumped to stderr and can also be automatically emailed to a configurable address. The underlying structure of the state report consists of a backtrace of the application. During the backtrace, as much information as possible as provided about each method call. This includes: - the class & address of self - the name of the method called - the type and value of all arguments - for args of type (id), the class of the object passed (and address) - for args of type (char *), the contents of the string - for args of type SEL, the name of the method During this reporting process, CrashCatcher takes measure to make sure that all data being examined is valid. Whenever CrashCatcher encounters a variable of type (id), it makes every attempt to provide the object with an oppurtunity to identify itself and provide commentary about the state the object was in when it crashed. (Example output is shown below-- gdb output of the same bactrace is given below that for comparison). CrashCatcher operates as a completely non-obtrusive addition to the runtime environment. It has a less non-obtrusive mode that can catch +all+ method calls sent to freed objects-- very useful during the debugging phase of an application. It is completely configurable via a clean and concise API. CrashCatcher also provides a number of debugging functions that aid in the validation and generation of reports within any class that wants to provide custom reporting information. The underlying technology is based on code provided in the talk entitled +The Zen Of Debugging+ given by Julie Zelenski at the laste NeXT World Expo. Obviously, this technology is useful to all developers of NS based applications. Questions: - How much is technology like this worth to you? - What form do you want it in (source? library? if source, are you willing to pay the extra $$$$ for a source distribution?) While I'm not at liberty to freely distribute CrashCatcher, I have been given the go-ahead to develop some kind of a marketing strategy for CrashCatcher. Please reply with feedback, and I'll see what I can work out to ensure that this technology is available to developers (I have found it to be extremely useful and would have a hard time living without it now). thanks, b.bum CrashCatcher sample output follows: ====== CrashCatcher Automatic Report ====== does not recognize selector -doFoo:bar: Backtrace follows: 0]: Object(0x00a000): + CC_printBacktrace 1]: Object(0x00a000): + CC_dumpBacktrace: CC_dumpBacktrace:(char *): "does not recognize selector -doFoo:bar:" 2]: KillerController(0x0f0844): - error: -CC: (0x000001)<<corrupt (char *)>> error:(char *): "does not recognize selector %c%s" 3]: KillerController(0x0f0844): - doesNotRecognize: -CC: (0x000001)<<corrupt (char *)>> doesNotRecognize:(SEL)doFoo:bar: 4]: KillerController(0x0f0844): - forward:: -CC: (0x000001)<<corrupt (char *)>> forward:(SEL)doFoo:bar: :(ptr)0x3fff42c 5]: KillerController(0x0f0844): - doFoo:bar: -CC: (0x000001)<<corrupt (char *)>> <<objc_meth structure not found>> 6]: KillerController(0x0f0844): - dieMethNotImplemented: -CC: (0x000001)<<corrupt (char *)>> dieMethNotImplemented:Matrix(0x0ef1a8) 7]: KillerController(0x0f0844): - perform:with: -CC: (0x000001)<<corrupt (char *)>> perform:(SEL)dieMethNotImplemented: with:Matrix(0x0ef1a8) 8]: Application(0x0eb560): - sendAction:to:from: sendAction:(SEL)dieMethNotImplemented: to:KillerController(0x0f0844) -CC: (0x000001)<<corrupt (char *)>> from:Matrix(0x0ef1a8) 9]: Matrix(0x0ef1a8): - sendAction:to: sendAction:(SEL)dieMethNotImplemented: to:KillerController(0x0f0844) -CC: (0x000001)<<corrupt (char *)>> 10]: Matrix(0x0ef1a8): - sendAction:to: sendAction:(SEL)dieMethNotImplemented: to:KillerController(0x0f0844) -CC: (0x000001)<<corrupt (char *)>> 11]: ButtonCell(0x0ef2f8): - _sendActionFrom: title: "Method Not Implemented By Class" _sendActionFrom:Matrix(0x0ef1a8) 12]: ButtonCell(0x0ef2f8): - trackMouse:inRect:ofView: title: "Method Not Implemented By Class" trackMouse:(ptr)0x0eb570 inRect:(ptr)0x3fff6f2 ofView:Matrix(0x0ef1a8) 13]: ButtonCell(0x0ef2f8): - trackMouse:inRect:ofView: title: "Method Not Implemented By Class" trackMouse:(ptr)0x0eb570 inRect:(ptr)0x3fff6f2 ofView:Matrix(0x0ef1a8) 14]: Matrix(0x0ef1a8): - _mouseDownNonListmode: _mouseDownNonListmode:(ptr)0x0eb570 15]: Matrix(0x0ef1a8): - mouseDown: mouseDown:(ptr)0x0eb570 16]: Window(0x0f1410): - sendEvent: title: "Chooose your fatality..." sendEvent:(ptr)0x0eb570 17]: Application(0x0eb560): - sendEvent: sendEvent:(ptr)0x0eb570 18]: Application(0x0eb560): - run 19]: Function [0 "args"] () ====== end crash report ====== gdb stuff for comparison-- (with comment marking lost frame) Program received signal 6, IOT trap 0x5007974 in kill () (gdb) bt Reading in symbols for CrashCatcher.m...done.

I have a script that does this, but it is need of some maintenance, and I am looking for an alternative. Cheers, Robert

It works. No it doesn't. At least not unless you define _POSIX_SOURCE (maybe _NEXT_SOURCE will suffice too). This is due to stupid header file design in NS 3.1. They need either of these defines to define a lot of useful things, especially in bsd/sys/....h files. It seems like the cc from NeXT doesn't always have this problem, haven't checked if it defines one of these macros, but probably. I now use gcc 2.5.2, looks good so far. BTW: This helps for installing libg++-2.5 - similar problems. For the unexperienced: define the flag by adding (incl. the quotes) "CFLAGS=-d_POSIX_SOURCE" to your make command. And if you are at it, you can also set "-O2", like "CFLAGS=-d_POSIX_SOURCE -O2". If you have to compile something with C++, then you might also need "CXXFLAGS" with the rest identical to the CFLAGS version. Bye, Uli

There is a package by Paul DuBois of RTF processing tools on ftp.primate.wisc.edu, in pub/RTF. One of the tools is rtf2troff, which translates rtf to troff. Since your NeXT already has "ptroff", you could put together an rtf-to-postscript translation script by doing rtf2troff foo.rtf | ptroff -t (and you could then lpr the output if you needed to print it) and this wouldn't require anybody to be logged in. Now in spite of the heroic efforts of this package to parse rtf code, unfortunately this isn't really a good solution. The rtf2troff stuff admittedly sidesteps a whole lot of issues (such as not really recognizing that a document has different fonts in it.) So, this might be a place to start looking if you wanted to do some hacking on your own to come up with a suitable rtf-to-postscript tool but I don't think it's quite usable right out of the box. Now, for another approach, thinking out loud here - the Text object already has provisions for reading in an rtf file, and writing its own postscript code to a stream. I wonder if you could write a program that would run from the command line, create a Text object, read an rtf file into it, and then write the corresponding postscript code to standard output. I wonder if there's any chance something like this would work, or would you need all the overhead of Windows and the window server and so on, which would mean it couldn't work from the command line when nobody was logged in....

Good guess! The _obvious_ approach is to use - printPSCode:, which at some point calls - beginPageSetupRect:placement: (View). That method performs a lockFocus (yes, it's documented), which depends on the Text being in a Window's View hierarchy *and* a real Window Server window existing. Boo, hiss! [No, I haven't tried overriding - beginPageSetupRect:placement: and - endPage.] -=EPS=- -- So much for the "NEXTSTEP Advantage" of being able to print something without writing pages and pages of code.

This card is really simple and can be controlled with I/O some ports (no interrupt, ...). After reading some of the (poor) NeXT documents on the subject, I find that the outb/inb/outw/inw macros could do what I need. Before writing the driver, I'd like to test the sequence of my writes and reads on the ports from a user-level process. I have written a little program that just tries to write to a port but it just stopped after the error "Illegal Instruction". According to the NeXT docs, these functions/macros are not required to run in kernel-mode... is it really true ? Finally, I'd like to access my card through a /dev/blabla file. The user should have the possibity to open this device, and to write and read some data to and from it. Is it easy to do with NEXTSTEP, what kind of driver should I write in this case ? Nicolas Droux

Submissions should be e-mailed to next-announce@digifix.com where the moderator (Scott Anguish) will screen them for suitability. comp.sys.next.bugs A place to report verifiable bugs in NeXT-supplied software. Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. comp.sys.next.hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. comp.sys.next.marketplace NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. comp.sys.next.misc For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! comp.sys.next.programmer Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. The NEXTSTEP programmer FAQs are posted here. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. comp.sys.next.software This is a place to talk about [third party] software products that run on NEXTSTEP systems. comp.sys.next.sysadmin Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. related Newsgroups comp.soft-sys.nextstep Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. comp.lang.objective-c Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. comp.object Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original comp.sys.next no longer exists--do not attempt to post to it.) Exception to the crossposting restrictions: announcements of usenet RFDs or CFVs, when made by the news.announce.newgroups moderator, may be simultaneously crossposted to all c.s.n.* newsgroups. --------------------------------------------------------------------- Thanks to Michael Ross at antigone.com, the main NEXTSTEP groups are now available as a mailing list digest as well. next-nextstep-d next-advocacy-d next-announce-d next-bugs-d next-hardware-d next-marketplace-d next-misc-d next-programmer-d next-software-d next-sysadmin-d (For a full description, send mail saying LISTS to <digestif@antigone.com>).

Here's a pseudo-definitive answer from someone who just bought a whole app that performs RTF->PS conversion and has seen the source code... 8^) Eric's last remark isn't fair. RTF is a general-purpose spec with many directives that require the rendering app to know information that only the WindowServer can supply easily, like font metrics. To give one simple but common example, RTF text doesn't specify line breaks, only paragraph breaks. That means the rendering app needs to calculate how much text will fit on each line given the current margins and indents, the individual character widths, and the paper size specified. Then it needs to calculate how tall each line is, given the rectangular union of the font height metrics for each font in the line, and determine whether that line fits on the page or should be moved to a new page. NOT EASY! That's probably why, as an earlier poster pointed out, rtf2troff is so crippled. The optimal solution is to write PS code in the first place, rather than RTF. Failing that, filter the text through rtfascii and then enscript it (see the man pages if you're not familiar with those programs). You'll lose the formatting info, but it will print. -- Gregory H.

NOT EASY! Not easy, but done for you by the Text object. But I think you're missing the point. My complaint is that there's a seemingly gratuitous dependency on the Window Server in the PostScript output methods. Printing occurs in a *different* context from display--why should printing even bother doing something that can only be performed in a display context? (At best, I can come up with some weak rationalizations.) I'll work on it some more. Sigh. -=EPS=- -- Bill? Trey? Bryan? Paul?

Message-ID: <CG7F30.MHz@ny.shl.com> Sender: usenet@ny.shl.com (Net News) Organization: SHL Systemhouse Inc. Date: Tue, 9 Nov 1993 03:01:46 GMT Yes it's TRUE!!! Conrad is indeed leaving NeXT!!! As with all things at NeXT these days it was not has decision!!! Conrad's role at NeXT over the last five years has changed greatly. In the beginning Conrad was the System Engineer for the northwest region. He was responsible for the five northwest states plus Alaska. He then moved onto help developing the campus consulting program. Which in the beginning was very important to NeXT because they were marketing only to University's and Colleges. After the program was up and running Conrad moved onto his current assignment, that of User Group coordinator. As coordinator, Conrad has been in charge of managing over 400 User Groups worldwide. Conrad has been an important resource to many in the community. One of his responsibilities is to make sure that all the user groups are kept up-to-date with the current goings on in the NeXT realm. He's also responsible for all the User Group activities at NeXTWORLD EXPO. Over the years Conrad has been one of NeXT foremost evangelist! It seems to me that Conrad's guiding principle for his work has been "I have never met a man/woman I did not like!" While telling one of my friends about this. He replied,"I thought has was a valuable resource for them?" I also thought that this was the case. Another individual described Conrad as, "The voice of NeXT on the internet!!!" I think this best describes how people fell about him. Conrad was one of the ONLY people in NeXT who posted regularly to the net. I know that this sounds like an obituary for him. And maybe it should because with his absences from the NeXT community it will fell that way. His loss will be greatly missed in the community!!! I wish him well in his next endeavor!!! - Michael -- --------------------------- Michael McMahon SHL Systemhouse Inc. mcmahon@ny.shl.com (NeXTmail) 212.303.5500

I think that's much longer than the industry average (I'd guess about 2 years). Turnover in the computer industry is very, very high relative to other industries. The industry is fast-paced and I'm not sure if turnover is the cause or the effect. I, too, am curios about the circumstances of Conrad's exit. Is it that user groups don't fit with NeXT MCCA focus?

I have been using a simple app which draws into a custom view object. This was originally hacked from the Plotter example code. Inside the subclassed view I had two main methods - initFrame ... { // work out the size of the frame etc } - drawSelf ... { // fill background // set foreground colour // if initialised draw contents } This worked well with the drawSelf using a switch to select the contents drawn in the view. So, I decided to get clever :-( For each of the types of drawable selected in the switch statement I decided to subclass. ie View MyView MySubView1 ... MySubViewn I kept all of the common code in 'MyView' as would be expected. The delegate id in 'MyView' is used to point to the subview in use. There are various buttons etc which control the views. These are connected to 'MyView' which is common to all subviews. The problem is that I get all of the initFrame methods reporting when run before appDidInit is called, but none of the drawSelf methods seem to be called even when on of the subviews is explicitly created. Any ideas? Andy (going rapidly) Gray

So I replaced the standard error handler for these cases with my own which just raises an exception. The exception handler can then inform the user about the problem and ask him if he wants to abort() the program or continue on his own risk. 1. Access the global '_error' variable and change it: extern void (*_error)(Object *, const char *, va_list); _error = gentleError; 2. Write a new error handler: void gentleError(Object *obj, const char *fmt, va_list args) /* Simplified version w/o error checking */ { static char buffer[2048]; int n1; sprintf(buffer, "%s ", [[obj class] name]); vsprintf(buffer+n1, fmt, args); NX_RAISE(..., buffer, ...); } Like vprintf() I don't use the 'va_start' and 'va_end' macros here. It works so far (since 30 minutes). What do the NeXTSTEP gurus think about it?

Date: 11 Nov 1993 13:52:27 GMT Organization: University of Bergen, Norway Distribution: world Message-ID: <2btg2r$sga@due.uninett.no> Hi. I'm buying a printer for my NeXT, and have come down to a choice between two printers - the HP DJ550C and Canons new BJC600. They cost the same at the offers I've received. Easy question - does the BJC600 work on NeXTSTEP? Here's why I wonder... I know that there are PD support programs (drivers) for the HP, but the quality of the Canon looks much better, both output, use of ink, and cost per page. I have verified with Canon that the engine is _better_ tha the BJC800 used in the NeXT Color printer. However, although Canon said that the 600's control language was compatible with the 800, they beleive that NeXT has designed their own controller for the NeXT Color printer. I have looked at the printing package and modified a PPD and pmdb file for use with a 600 on a serial port (slow, I know) through the standard NXColorBJ driver. I haven't a printer to try - but if the controller is Canons standard in the NeXT printer, it _should_ work with the 600 as well... So - I _really_ want to buy the Canon. Is there: 1) existing drivers in 3.1, 3.2, or available PD/Shareware to controll this model? 2) anyone out there who has used this printer with NeXTSTEP? 3) anyone out there who knows that a driver is under way? I would buy the printer today and use it in Epson (B/W) compatibility mode for 6 months if I knew a driver was being written... I'd write it myself if I had the faintest idea how to :-) I imagine with all the Intel users getting NeXTSTEP _someone_ must have a BJC600 they have hacked to work with NS, no? Please e-mail replies.

Message-ID: <2botrh$3a5@rosie.next.com> References: <2bop0r$75o@sol.ctr.columbia.edu> Well, the subject of Fat Binaries has been pretty much discussed to death, but here is some info: 1) Fat binaries do NOT share data or Objective C info. 2) Fat binaries DO share resources (nibs, tiffs, etc...). App Name m68k i386 .app % additional for i386 Concurrance 885 967 7058 16 Notebook 557 622 1410 78 WetPaint 304 320 2925 12 Diagram 1114 1180 6924 20 Sizes in Kbytes. %additional = i386 / (.app - i386) So there is some savings by sharing the resources. Remember, you can't assume you can share data between executables of different types. The C compiler may generate different sized structures for different cpu types because of alignment and endian-ness. We thought of several ways to get this sharing. We went with Fat binaries because they made the least amount of impact on the rest of the system. 1) Existing Makefiles could be changed to deal with them by adding flags to the "cc" lines. 2) They could be executed directly from the command line. 3) They could be executed by "execl(3)" in the c library. 4) NXBundle wouldn't have to change its searching logic. 5) Dynamic loading works, whether using NXBundles, rld_load, or objc_loadModules. 6) Minimal work needed to be done on the existing development tools (cc, ld, ar, gdb, etc...) Finally, we were able to present a clean picture to the developer. ProjectBuilder presents you with your cpu choices and you pick the one(s) you want. In general, neither the developer or the user spends much time dealing with the differences between fat and thin executables. Dave Moore NeXT Computer, Inc. Software Development Tools

Message-ID: <2brmmh$4ej@rosie.next.com> TablePrinterPalette (DatabaseKit) -- this example requires NEXTSTEP 3.1 or later TablePrinterPalette is an Interface Builder palette which nicely formats and prints DBTableViews. Changes to TablePrinterPalette: This is a new MiniExample. TTools (Appkit) -- this examples requires NEXTSTEP 3.1 or later This MiniExample is an advanced IB Palette primer. The prerequisite knowledge for this is a good understanding of Interface Builder and Objective C including knowledge of the Protocol and Category language elements. The palette illustrates: How to palettize a simple view, window, and object. How to provide your palettized view or object with an inspector in IB. How to write a custom connection inspector and custom connector objects for your palettized object. How to access your superclass's inspector. How to effectively palettize Matrix without restricting its prototype cell class. How to palettize an object that uses the target/action connection paradigm in IB. How to browse the class hierarchy. How to implement a complete object editor. How to generate a library from your palette project so that applications can link in the palette code. How to automatically generate a library .h file, and precompile it. How to bind to instance variables that are not of type id (hyper advanced). Changes since TTools 1.0: Basically everything. The Ranker and Timer objects are the same, the AlertPanel object has been thrown away, and everything else is new. Timer changed a bit; versioning was used, so old instances of Timer should be fine. Also, this version works only in 3.1, not in 3.0. It requires minimal Makefile hackery to make it work under 3.0, but it was decided the project was large and confusing enough as it is. ScrollViewDeluxe (AppKit) -- this example requires NEXTSTEP 3.0 or later This object is an enhanced subclass of ScrollView. It adds the following features: Support for a 'top view', a view at the top of the scroll view that scrolls horizontally with the document but remains static when the document is scrolled vertically. Support for a 'left view', a view to the left of the scroll view that scrolls vertically with the document, but remains static when the document is scrolled horizontally. Automatic support for rulers. Support for synchronizing other scroll views. Automatic support for page up/down & left/right buttons. Automatic support for zooming. Support for adding arbitrary views to the vertical and horizontal scrollers. The ScrollViewDeluxe palette allows you to create a ScrollViewDeluxe by command-clicking the 'Group in ScrollView' menu item. Changes to ScrollViewDeluxe: This version of ScrollViewDeluxe fixes a bug in the 'Group In ScrollView' feature. The previous code caused 3.0 versions of the palette to crash InterfaceBuilder and 3.1 versions of the palette to archive ScrollViews incorrectly.

What can I do to concatenate all these NXImage in > only one ? Depends on what you mean by "concatenate." If you mean that you want to have one large image that contains all of the images (say one after another, vertically), then you can do something like: /* sizeOfBigImage is the size of the concatenated image images[] is the array containing the images to be concatenated... */ NXImage *bigImage = [[NXImage alloc] initSize:&sizeOfBigImage]; NXPoint loc = {0, 0}; unsigned cnt; if (![bigImage lockFocus]) return; /* Bail out */ for (cnt = 0; cnt < numImages; cnt++) { NXSize *size; [images[cnt] getSize:&size]; loc.y += size.height; [images[cnt] composite:NX_COPY toPoint:&loc]; } [bigImage unlockFocus]; Writing the image out to a .tiff involves creating a stream and writing the image out to it with writeTIFF:. Here's one way to do this, using a memory stream: NXStream *stream = NXOpenMemory (NULL, 0, NX_READWRITE); [bigImage writeTIFF:stream]; if (NXSaveToFile (stream, fileName)) { /* Couldn't save to desired file... */ } NXCloseMemory (stream, NX_FREEBUFFER); This approach of concatenation has several problems; first of all, because you are using the window server, the final image will be in one of the depths supported by the window server. Thus if your original TIFFs were 1-bit, the resulting image will be 2-bits (as the windowserver doesn't support 1-bit windows). Or if your original TIFFs were CMYK images, the resulting image will be RGB. Similarly, even if the original images had multiple representations (for instance, a color rep, a gray rep, a low-res rep, etc), the final image will be a concatenation of only one of the reps from each image. This all is probably not an issue if the resulting image is meant for on-screen use only and won't be saved. Otherwise you might need to do a more complete job, depending on the kind of input you expect. Ali, Ali_Ozer@NeXT.com

Because the 0,0 is in the lower left corner, you need to change the code around a bit.

Well, the BJC600 is a very nice color printer. But in my opinion, Canon compromised black print quality in order to get good results with color. The HP 550C, on the other hand, gives you very good color without compromising black only output. So I would say that if you need only a color printer, buy the BJC600, but if you want a color printer that will also give you good black print quality then take another look at the DJ550C. Another option would be the DJ1200C which is a great color printer with great black print quality and it supports Postscript.. i. -- PS. I tried to make a fair comparison, but of course I am very biased... I work for HP, AND I worked on the HP550C.

I have read through almost all online documents and header files concerning DBKit user interface layer, but strangely enough, there seem to be no official way to know which cell I'm actually editing (in other words on which row and column the Window's field editor object resides). There IS a delegate method called tableViewWillChangeSelection, which is called anytime the user attepmted to change the current editing position either by cliking other field or entering TAB or RETURN key in the current field, but even in that method, it is impossible to know from which field you came or to which field you want to go. As far as I know, the only way to know the current editing field is, first get the content of the current editing field by writing TextFilter function for the window's text object, compare it with each property value of the current selected record of the DBRecordList object, and guess which column you are most likely to be in. Obviously, this does't work in every case. (And of course, it's not an elegant way.)

If it's an application that you are writing, then you can probably point the defaults processing at any specific file you want. Of course that would mean you'd get all the defaults from that file, and none from the user's own defaults. You could also have your program open up the system defaults first, save those values away, and then re-open defaults using the regular defaults-processing. On the other hand, it would be nice if there was some standard place for putting defaults-settings that would be in effect for all userids on the machine. The user's own values would override them, but the system administrator could setup things such that everyone would start out with a different set of defaults than that which shipped with any given app. [as an example, it'd be nice for the system administrator to be able to set the CDDrive default for CDPlayer.app on NeXT hardware, so that all users start out with the right default drive] -- Garance Alistair Drosehn = gad@eclipse.its.rpi.edu ITS Systems Programmer (handles NeXT-type mail) Rensselaer Polytechnic Institute; Troy NY USA

(Of course you'd want to retain the current defaults API -- athough it isn't great it sure beats the NetInfo API.) The current programming style of putting the defaults directly in code seems to be the wrong thing to do -- I've been putting the defaults for my applications in an NXStringTable *.strings plain text file in the *.app wrapper and then read them in at runtime. A little messy but better than the current design as it is possible to modify the defaults without source on a system-wide basis. - Christopher

I wrote a method called - initializeBoard which reset the board to a startup state. At first I just called this method from within another method -configureBoard (initializes, then sets the board according to object parameters). Well all was working well until I decided to also initialize the board in the -initFromDeviceDescription method. The strange part about all this is that it initialized the board fine with the call from initFromDeviceDescription (I followed it with IOLog messages), but when I asked it to configure the board (and hence initialize the board) I got a System Panic with the message something like: -<3>: Objc error, object NatInstMIO16x does not respond to selector -<3> which I tracked down to be this call to - initializeBoard. When I comment out the call in initFromDeviceDescription, the other call works again (and I can call multiple times). I also thought it might have something special to do with the initFromDeviceDescription method so I provided another means of accessing it directly (here a subset of my setIntValue procedure, which I also use to have the driver execute methods by just passing in nothing, and other related code): - (IOReturn)setIntValues : (unsigned int *)parameterArray forParameter : (IOParameterName)parameterName count : (unsigned int)count { unsigned int temp, temp2, x; inputConfigType *tempConfig; if(strcmp(parameterName, SAMPLES_PER_TRIGGER) == 0){ temp = parameterArray[0]; if(temp<=65535) { samplesPerTrigger=temp; return IO_R_SUCCESS; } else return IO_R_UNSUPPORTED; } else if (strcmp(parameterName, SET_DEVICE)==0) { IOLog("setting device\n"); [self configureBoard]; return IO_R_SUCCESS; } else if (strcmp(parameterName, INITIALIZE_BOARD)==0) { IOLog("INITIALIZE_BOARD\n"); [self initializeBoard]; return IO_R_SUCCESS; } else { /* Pass parameters we don't recognize to our superclass. */ return [super setIntValues:parameterArray forParameter:parameterName count:count]; } } - initializeBoard { IOLog("initializeBoard\n"); [self clearBoard]; [self initAm9513a]; [self disableRTSIswitch]; return self; } - configureBoard { IOLog("Start configureBoard\n"); [self initializeBoard]; [self programChannelConfig]; [self setSampleTimer]; [self setSampleCounter]; IOLog("finished configureBoard\n"); return self; } So apparently the kernalLoaded driverKit objects are doing some funky stuff with objective C method translation. If I understand this Objective C stuff right, methoding is handled by the Objective C RunTime system, which is not running in the kernal(the kernal is not objective C). I switched the method over to a C function and I can call it from multiple places in my code (just not as a method). I hope this bug is fixed in 3.2 either through userLevel drivers or by someother means, because I want to be able to write driver code with methods and object level variable scopeing. Hope this is some help. Mike Haker Department of Chemistry, UW-Madison haker@whitewater.chem.wisc.edu

A graceful way of doing this is to add this at the start of your code: #define printf my_printf and provide a definition of my_printf() instead of redefining printf(). If you really want to override printf, here's a quote from "man ld": -m Only print a warning for multiply defined symbols and don't treat them as a hard error. The first symbol is used for linking and is the value of the symbol in the symbol table. The other symbols by the same name may be used in the resulting output file through local references.

What I want to do is to run the panel as modal from the start to the end of the launch, so that the user will not be able to use the app's commands before the launch is done. The NXApp delegate calls a method in another object when it receives the app:applicationWillLaunch: message, and this method begins a modal session for a panel. When the NXApp delegate receives the app:applicationDidLaunch: message, it calls another method in the same object which ends the modal session. The problems I have are the following: 1/ If there is no loop testing [NXApp runModalSession:&session], I got the following error messages: Exception handlers were not properly removed. Attempt to remove unrecognized exception handler. apparently at the beginning and end of the modal session. 2/ If I do a loop, or use runModalFor: directly, the app:applicationDidLaunch: message is not received.

I noticed through probing around with vm_stat and ps -u that if I create an NXZone and then allocate a large chunk of memory, use it, then destroy the zone, the memory does not reappear in the "pages free" count, according to vm_stat, and the process continues to be listed as having a large RSIZE. Thus it seems that memory flows into a process but does not flow out. It seems to me that the de-allocated pages should be returned to the OS, or am I wrong? I am getting very large swap files even though I destroy my large temporary zones conscientiously. The on-line docs don't tell what the relation is between VM, zones, processes, etc. Inquiring minds wanna know... .. anyone care to explain? Please email me since I don't check this group every day.

I am working in spare moments on reviving the NeXTStep WorldWideWeb application. It now uses the latest library from CERN. The big plus is that it is a hypertext editor, and so allows you create your own hypertext in a wysiwyg way. It now handles nested lists, etc.. Right now I am just putting images in... I have been out of the NeXTStep scene a little, so a bit of help would be useful. In particular, tell me how to put in an arbitrary image. The doc on the Text class says that replaceSelWithCell: is implemented but not replaceSelWithView:. That means I have to put a Cell in -- but how does one put an arbitrary image (loaded for example from a stream) into a Cell? There seem to be options only for creating Cells with named icons or text in them. This must all be possible with off the shelf objects. Pointers to examples which include graphics?

The answer is that '-d' is a compiler flag that generates intermediate-stage output files in Register Transfer Language (RTL), a lisp-like language that gcc uses internally while the compiler is working. The 'loop' file dumps the state of things at time of loop optimization, the 'sched' file dumps the state of things at time of instruction scheduling. This happened because we added what we intended to be a debug flag to the CFLAGS variable in Makefile.preamble. We typed "-dALPHA_RELEASE" instead of "-DALPHA_RELEASE", and the compiler picked up all flags it recognized in the trailing string. So if you notice weird files showing up in your projects, this is the reason. -- Gregory H.

Our solution is, as the above proposes, to use distributed objects. We have established a protocol which requires any dbclient that updates or creates db records to update two unique fields called "lastupdater" and "lastupdatetime" in a shared table. These fields are periodically queried by a distributed object server (called sybiff :) ) When sybiff encounters a new "lastupdatetime" it notifies all clients who have registered with it. In our system this registration takes place automatically after the sybase client login is accepted. Determination of what has changed and what if any its effects may be is left up to the client. In our system the user may be select what type of update action is to be taken, the choices are: ignore, flag, notify, and force update. Obviously a method like this has some drawbacks and is NOT suitable for systems which must maintain absoltute transaction integrity, but for our purposes it seems adequate.

I'm surprised you didn't ask yourself why the HP didn't give you the same error, because it is an error to do this in C It's perfectly legitimate to want to overload a function like printf. C does not give you direct support of this. C++ does give you direct support. You may try compiling your program like this: cc -ObjC++ test.c to use the Objective C++ compiler instead of the standard C compiler. C++ will mangle the printf function so that linkage is safe. If you ever need to use the system printf, you will have to call it like this ::printf(...)

I have no idea why, and I am looking for any input. My particular problem is: I have two apps, communicating with each other through distributed objects. One app creates objects from time to time, and passes them to the other app. This 2nd app needs a real copy of the object, not just a proxy. Sending it bycopy would be a possible approach, but as each object can be rather large (5MB or more) this approach seems not to be the best idea. Now when I implement the NXEncoding protocol, using encodeVM::, it first seems to work. Then, the app that created the object frees it. No problem. Then the receiving app (and now the only one still posessing it) frees it, too. What I get is a memory hole of the object's size. When I do this kind of object passing a dozen times you see where my memory is gone. When I free the object I deallocate the memory using vm_deallocate, and I get a confirmation that the memory was freed. When looking at ps -ux, and the system's performance, I know it wasn't. What's wrong? I am running NS 3.2 on a black system. Thanks for any help!

However, the hooks created will be executed at the login or the logout of any and every user that will work on that machine. Hopefully, the first argument of the hook programs is the user name. To install a hook program, use the following procedure: 1 - Open a terminal window. If you are not connected as user "root" make "su" to become root. 2.

Well, I apparently don't :-) I've always been about 1 pointer dereference away from being totally comfortable with hashtables and storage objects.

I'm currently writing some software which writes to any output volume (/dev/xxxx) using the write(2) library call. When writing to a floppy diskette (1.44MB) on the same machine to which the drive belongs, I can write until the disk is physically full and will then, as expected, recieve an error after which my program takes appropriate action. The program has the ability to send its data to another machine (say from a floppy-less cube to a station) via TCP using a client (the sender) and a server (the [remote] reciever). The reciever is started via rsh on the remote system in the background by a pipe(2) command (After starting or on failure to do so the server prints a message on stdout, which is then read from the pipe and analysed). The server works like a daemon, that is, it forks a child, which does the actual communication, then quits. The client can now send and receive data to and from the server - so far no problems. The server uses the same write(2) command to write to the output volume. Now, if I have a floppy (1.44MB) inserted with only 250KB free space, I can actually send 500KB of data, which will be written to the floppy WITHOUT the disk full error! The browser (and also ls) will show the file to be of 500KB and the file IS 500KB! I KNOW that this is not possible - and sure enough, trying to eject the disk fails as it is still in use. This can only mean that the excess 250KB are stored somewhere else. This doesn't bother me much, but: why don't I get the diskfull error when writing to the disk any more? Is this because the process is started with rsh, in the background and forks a child? I'm stumped! Anybody have an idea?

Date: Wed, 17 Nov 1993 06:52:18 GMT We have a DBTableView in a window connected to a Controller object (as the delegate). Everything we need to do (edit the columns in the DBTableView, scroll, etc.) works fine. Now, we need to add a Window delegate (to handle closing the Window) so we put in a windowWillClose: method in the same Controller object and make the Controller object the delegate of the Window. When we double click on one of the rows of the DBTableView, we end up in the windowWillClose: method, even though we have not done anything that resembles trying to close the window. Any ideas how this might happen? Is there a known bug in Release 3.0 DBTableView? Inquiring minds wish to know... Jon Rosen jfr@pdh.com

Everything that her code did depended on the order of things going onto the stack and which CPU registers were used for what, and all that is subject to change based on the underlying architecture. When the PA-RISC port comes out, this code will most likely have a difficult time working, since the PA-RISC calling convention does (at least under HP-UX) does *not* use the stack for subroutine calls in the way that the Motorola and the Intel do. Perhaps b.bum has already taken this into consideration and coded around this possiblity. Otherwise, we might all be in for a big surprise when NS/PA gets in our mitts and CrashCatcher simply generates another crash...:-( (Please tell me I'm wrong!) -cj -- ============================================================================== Chris Cleeland | NeXTMail: chris@milo.st-louis.mo.us BOS Dev.

Given this, NeXT >users are going to have to take it on themselves to send in fixes. This raises (for me at least) a rather important point. Who thinks that some effort should be made to get FSF a NeXT machine? I guess it wouldn't do any good unless somebody also purchased a support contract from them? In anycase I would like to make the following proposals. 1. Discuss wether getting them a machine would help matters any. 2. Somebody who relies on GCC (C++) for their work and who has plenty of spare time perhaps put together a binary consisting of the latest compiler and the latest libg++ for both archtitectures. Or at least make the Motorolla binaries available. How big would a binary (pkg) distribution be? The source now for Gcc alone is 6 MEG which is rather large. On another note: Where is the language definition of Objective-C going? Is a language definition of this rather simple language (simple compared to C++'s definition) necessary? C++ has the ANSI committee to look over proposed enhancements. Where's in Objective-C heading? Will we ever see private instance variables? etc etc.

Thank you everyone who responded, especially James E. Burns, and Marcel Weiher who sent in code. I modified Marcel's code to map grayscale onto a line in color space. With that you can actually convert black-on-white to anything, e.g., yellow-on-blue, or white-on-red, etc. Caveat: It doesn't work with "image" operator and many pattern fill schemes.

I thought that you could only print a view which was in a window. Allocate an off-screen window, make the view it's content view, and it should work. You should get a message about unlockFocus being sent to a view that is not in a window, which is why I assume you have attempted to override these methods. This message is probably a suitable hint.

As was pointed out to me via E-mail, this gross oversimplification of mine is not correct. The Control class inherits keyDown: from the Responder class. Any Responder object (Application, View, or Window) can be the first responder (if acceptsFirstResponder is overridden to return YES). However, the point I was trying to make was that making a TextField the first responder does not buy you much, and will not initiate text editing. Among other things, the inherited keyDown: method simply passes the message to the next responder. There is no functionality in the TextField (or TextFieldCell) class to perform text editing directly. What the edit:inView:... and select:inView:... methods of Cell actually do is position a Text object (the Window's field editor) directly on top of the Cell (and make the Text object the first responder). When you're editing a TextField, you're interacting with a Text object which is drawing on top of the TextField, not a TextField object. Yes, it's somewhat convoluted. But text editing is fairly complex, so it makes sense to make use of the existing functionality of the Text class. Given all that, now I'm wondering why TextField overrides acceptsFirstResponder (to return YES if it's selectable or editable). Since it does that, it seems like a lot of confusion could be avoided if TextField went on to override becomeFirstResponder with something like: @implementation TextField (TextSelection) - becomeFirstResponder { return [self selectText:self]; } With this simple addition, [window makeFirstResponder:textfield] does what most people expect to happen, i.e., begins text editing. But then, as explained above, after doing this the textfield isn't really the first responder, and that could perhaps lead to other confusion. (The only thing I can think of is an unexpected recipient for an untargeted action message sent down the responder chain.) By the way, I've tested this code (and the select:inView... code I posted previously). -- Ray Spalding, Office of Information Technology Georgia Institute of Technology, Atlanta Georgia, 30332-0715 Internet: ray.spalding@oit.gatech.edu (NeXT Mail accepted)

This is starting to worry me. Is DriverKit design really sound in the first place? I think NeXT *is* trying hard to solve this problem, but hasn't been able to fix it for several months, indicating that it is not probably due to errors or bugs in the code, per se. It seems like interrupt latencies are becoming too large under Mach and deferred/indirected processing by DriverKit. The fact that there are many comm programs for the PC's that can do 38kbs even on very slow PC's (with direct interrupt processing) indicates to me that perhaps DriverKit's overhead could be just too much for it to work reliably. If that's the case, other devices such as data acqusition boards may also have difficulty in its drivers, as they can also generate interrupt at short intervals as do serial devices. This doesn't look good.

Unfortunately, the technique used above SOMETIMES works. It depends on what you do with the pointer you get back from "return aSurName". If you immediately copy the string with NXUniqueString or NXCopyStringBuffer (or any similar routine) you might be okay (very sloppy and maybe safe, but don't count on it). On the other hand, if you just retain the returned pointer and continue, you are playing Russian Roulette with your program. There are a variety of ways to handle this potential problem. Which one you use will depend greatly on what you are trying to accomplish. Note, in all of these code snippets, I am assuming that "name" is correctly allocated and hasn't been handled in a manner similar to the original version of the surName method (see above). I am also assuming that maxSurNameLength is 25. 1) malloc memory during your method to hold the string (rather than allocating some off the stack) and return the pointer to this storage. You have to be careful about freeing this memory later. - (const char *) surName; { char aSurName[maxSurNameLength + 1]; sscanf(name, "%25[^,]", aSurName); return (NXCopyStringBuffer(aSurName)); } 2) Have a static variable for the Class (be careful with this one, all instances use the same storage area for static variables -- they are really more like Class variables). static char aSurName[maxSurNameLength + 1]; [more program here...] - (const char *) surName; { sscanf(name, "%25[^,]", aSurName); return aSurName; } 3) Have an instance variable allocating the appropriate amount of storage (char mySurName[maxSurNameLength + 1]). Use the same code snippet as #2. 4) Have a pointer instance variable and malloc the appropriate memory in your instance init method. (char *mySurName). - init { [super init]; mySurName = (char *) malloc(maxSurNameLength + 1); return self; } and continue with code snippet from #2.

This allows the following implementation: char defaultBuffer[SOMESIZE] char *emergencyBuffer = NULL; int eBufferSize = 0; - (const char *)surName { int len = (int)(index(name, ',') - name); int newLen; if (len < SOMESIZE) { strncpy(defaultBuffer, name, len); defaultBuffer[len] = 0; return defaultBuffer; } else if (len < eBufferSize) { strncpy(emergencyBuffer, name, len); emergencyBuffer[len] = 0; return emergencyBuffer; } newLen = len+1; /* Minimalistic */ if (emergencyBuffer == NULL) { malloc(emergencyBuffer, newLen); } else { emergencyBuffer = realloc(emergencyBuffer, newLen); } if (emergencyBuffer == NULL) { eBufferSize = 0; return NULL; } eBufferSize = strncpy(emergencyBuffer, name, len); emergencyBuffer[len] = 0; return emergencyBuffer; } While this may seem like a lot of code (it's not really - and could probably be distilled out into a "static buffer handling class") I favor it for it's low memory-thrashing potential. Having worked with large systems for so long, I've grown a distinct aversion to lots of little mallocs. There are a couple of things that can be tuned in this routine. The size of the static buffer should be large enough to catch %90 of the cases without being obscene (for this case, about 20 would be my guess). The formula for calculating the new buffer size can be teweaked. Elegant? Depends on your definition. I usually consider functionality as part of elegance, so to me, something that barfs if you go beyond it's expected input isn't elegant. Or, alternatively, something that causes thrashing - CPU or memory - isn't very elegant either. And especially not something that isn't portable or relies on processor specifics. Especially if it's going to be hidden in an object. -- Scott Byer NeXTMail: byer@mv.us.adobe.com Adobe Systems Incorporated These are *my* opinions, and 1585 Charleston Road, P.O.

This was fixed in >>2.5.3. While this is accurate, it is somewhat unfair of me, since at least three other show-stopping bugs were also introduced into gcc2.5 and libg++2.5, problems that Cygnus people have now tracked down -- these bugs were worse in many ways. I mentioned this bug because someone asked for a nasty bug that had been fixed (the others are still in 2.5.4). I intended no ridicule of Ron; I've introduced many bugs into software myself. My point was quite different from the point Ron infers (you're *way* too thin-skinned, Ron). OK, here's the context. Here's the change that introduced the problem I was refering to (from the gcc ChangeLog file): Thu Oct 28 19:01:33 1993 Ron Guilmette (rfg@netcom.com) * cp-method.c (hack_identifier): If an overloaded identifier can only mean one thing, it can only mean one thing. The comment above and the patch seem reasonable, but it completely breaks overloading of static member functions. The reason the patch was introduced was to fix code like void foo(); void bar(); typedef void (*voidfn)(); main () { voidfn f = 1 ? foo : bar; } (and I'm sure Ron will correct me if he had a different case in mind). Later in the ChangeLog, this patch was taken out again: Tue Nov 9 15:33:45 1993 Jason Merrill (jason@deneb.cygnus.com) * cp-method.c (hack_identifier): Undo rfg's earlier patch. Perhaps it would have been better to try to figure out how to fix the patch to work correctly in all cases; this is the kind of quick solution a company whose business is support will choose when customer code breaks. Since Jason took Ron's patch out, the code above is broken again, but at least overloaded static members work. rfg@netcom.com (Ronald F. Guilmette) writes: >It is rather humorous to note that people who are totally uninvolved with >the actual code of the g++ front-end and/or whatever meager attempts people >occasionally make to help fix its many bugs somehow become gifted and >insightful when it comes to laying blame for things which they do not >even know about, let alone fully understand. They also serve who only send in well-documented bug reports by the hundreds, and who spend considerable amounts of time working with the maintainers to make sure the job's done right. I've spent a great deal of time testing proposed changes from Cygnus before they were inflicted on the world (even Cygnus customers) and this is an important function. When I was first working with Cygnus, I sent them compiler patches directly, but I've since found that it's less disruptive to send the outline of a proposed fix and let them decide how they want to do it. So you won't see my name in the ChangeLog. >In any event I'm sure Joe will be pleased to know that I (like many other >people before me who have been generous enough to donate time and energy >in futile attempts to get g++ improved) have learned my lesson, and I >promise to make no further attempts to help the g++ maintainers to do >the job which they (unlike me) are being PAID to do. This is one possible lesson that one can learn. Another possible lesson that can be learned is that improving g++ is a difficult and tricky job, and half the time it seems that fixing one bug causes another one to appear. This might lead one to be gentler with the g++ maintainers. If you now wish to take your ball and go home, that's your choice, Ron.

You won't notice the difference (between the fractional and integer formats) on most operations(ADD f'rinstance)..but there are several exceptions to this... The GCC56k compiler is good for edification and entertainment, but the code it produces is extraordinarily inefficient. I know for a fact that the particular version I've got doesn't support parallel data moves (which saps half of your performance right there)..Motorola makes a C compiler, and while one would reckon it to be fairly dangerous (I don't know *personally*; never had a chance to use it), I remain fairly convinced that the only way to write fast code is with assembler. d!ll!yd (the tough coughs as he ploughs the dough)

Pretty sure its big-endian, it may also go both ways. I don't think endianness really matters anymore, almost all new designs are either designed from the start to go both ways or are being modified to do so.

I suppose (with options 3 & 4) you could return a pointer to the string to the method caller but then you risk someone modifying the string from outside the class - though if you mark it const the compiler will warn them. and there is always NXUniqueString. but I wholeheartedly agree that none of these solutions are elegant, and its a result of C being such a low level primitive language with poor support for returning variable length data on the stack among other things. ------ begin digression --------- this wont help in ObjC much, but it may be interesting to some to see how this problem is solved efficiently and elegantly in Ada. I wish it were as easy in C. first there is a predefined type called string that is simply an unconstrained array of characters. unconstrained means that the bounds are not fixed in the type definition. (similar to char[]) type string is array (positive range <>) of character; you can write functions whose return values are unconstrained arrays. "... args ..." just means I left them out of the example, thats not Ada. function name (... args ...) return string; a function may declare constrained objects on the stack (automatic variables in C except that the size can be determined when the function is invoked, as in alloca but better) function name (... args ...) return string is local_var : string (1 .. x); -- stack allocation, x could be a parameter begin -- assign to local_var return local_var; end name; and here's the great part. most compilers implement this by NOT changing the stack pointer after the call -- to give the caller a chance to use the "temporary original" stack allocated string. They then pop the stack pointer after the final reference to the function result. this would be very error prone and risky if done by hand, but is a perfectly safe (and valuable) compiler optimization. the semantics are as if a copy of the string was returned, but the implementation is much more efficient. this works because in Ada (unlike C) it is possible to return an array (conceptually) rather than just a pointer to an array, and it is not possible for the caller to modify a function result without either saving it via assignment or declaring the function to return a "pointer to a string" instead of returning a string. so the compiler can tell when this optimization is safe. there are other nice things as well. you can concatanate strings using the & operator, which can be efficient due to the above optimization. so you can write return "this" & "that; rather than tmp = malloc(9); strcpy (tmp, "this"); strcat (tmp, "that"); and require the caller to remember to call free. this is real nice when calling functions too. put_line ("your name is " & name(currrent_user) & " other string"); no temporary variables required. no heap storage required. the return value from function name is passed to "&" to be concatanated with the other strings, that return value is passed to put_line, and the compiler removes all the residue from the stack by the time put_line returns. you can also assign slices of 1-D arrays or strings; x(1..10) := x(5..10); which can be efficiently implemented as a block copy, where is C you either typically write for loop (which will be less efficient) or call memcpy (which is good but not very strongly type checked at compile time). even though C has strengths, its not a very good language for easily and efficiently working with strings IMHO. you often see either hard coded limits on bufffer sizes or dynamic memory being allocated (and hopefully freed) in little tiny fragments just there aren't good safe flexible ways to use the stack efficiently for returning variable length data. -- Alex Blakemore alex@cs.umd.edu NeXT mail accepted

In Unix, this can be a BIG problem. #define soapbox ON REMOVE ALL STATIC VARIABLES FROM YOUR CODE! THEY ARE THE ENEMY OF GOOD PROGRAMMING! THAT'S ONE BIG ADVANTAGE OF OBJECTS. THE STORAGE IS DYNAMIC AND CAN NEVER CAUSE THESE KINDS OF PROBLEMS. THAT'S WHY CLASS VARIABLES ARE NEEDED ALSO, BECAUSE USING STATIC VARIABLES AS PSEUDO-CLASS VARIABLES SUCKS! #define soapbox OFF I would put the surname as an ivar. If you REALLY want to conserve memory (i.e., not double-store things), build a UniqueStringClass that allocates strings in a continuous memory heap and has pointer/lengths to the strings. This way, you could store the first/last name as one string and also store pointers (and lengths) to the first and last names separately. The disadvantage of this is that you have to write your own string-handling functions since all C functions use null-terminated strings (boo! hiss!) but this can be encapsulated in the class. Add to that a unique string facility (but without the hassle of not being able to FREE the strings when you no longer need them) and you should have a pretty elegant string class capable of doing what you want.

So I write such a filter, test it on the command line --- no problem. So I look up the installation details in the doc's (found zero) and check the given filters (yes, the "PostScript for chosen Printer" etc. reside in /NextLibrary/Servics!). Finally, my filter shows up. I filter a file through it and my filter writes a complete file and finishes off neatly --- and the calling App (in these test cases Edit.App) crashes with a memory exception in NXPing()!

After having upgraded from Release 3.0 to Release 3.1 on my NeXTstation, I'm having a lot of problems running one of the apps I've written. This app uses Distributed Objects and is in three parts: Client, Server and SharedLib which is a library of mainly Storage subclasses that the Client and Server share and which are able to send a copy of themselves across applications (i.e. from the Client to the Server and vice versa). When compiled and running under 3.0, all goes well. In the three other combinations (i.e. compiled 3.1/running 3.1, compiled 3.0/running 3.1 and even compiled 3.1/running 3.0) the apps crash in pretty much the same kinda way. In the normal course of events, the user creates a simulation with the Client and then sends it to a Server (a non-AppKit prog) which runs the simulation and sends data back to the Client that can then be displayed for the user. The first time a simulation is sent to a Server all is well. The second or third time a simulation is sent (from the same Client, but to a different Server, one Server only runs one sim), the Client crashes. This is where things get complicated because there are many different ways in which the crash manifests itself. I'll try and list the most common. Sometimes the Client will crash in before even getting to the Client code (i.e. it might get lost in an objective-c function like _cache_expand, the Client's Application object might send a message to the Object class instead of the proper object, etc). Sometimes gdb doesn't even realize the Client has crashed. On other occasions, the Client will crash in the alloc/init phase of a FullCopyList (a List object that copies its objects across apps, taken from one of the NeXT examples), or when drawing something on the screen, a display message might be sent to one of the SharedLib Storage objects which is obviously followed by a crash. What is even stranger is that when I single-step through the code that starts a Server and sends it a simulation, 95% to 99% of the time I get no crash whatsoever. I can start a large number of Servers without trouble. Stranger still is that the Servers sometimes crash and become immortal: they are totally unkillable and hog the CPU like hell. When I have one or more of these babies running in the background, it's impossible to turn the station off normally since it'll try to shut the processes down and wait (and wait and wait :-( until they do. Well there you just about have it, my litany of woes is at an end :-) I get the impression that the trouble might be due to the compiler badly linking in the SharedLib to the Client but then why does compiled 3.0/running 3.1 crash while compiled 3.0/ running 3.0 works OK? Thanks for reading this far. If you have any solutions, ideas, suggestions, thoughts, ... anything! (I'm getting pretty desperate <8-( I'd love to hear from you.

Anyways, the first (and more important) is "putenv" which apparently should be used to define a variable under the current shell (NS2.1 does have getenv, which does the reverse). Is there something I can do about this? I tried using a SunOS include file that had putenv in it, but that really didn't go too well (I didn't mess with it much because I wasn't sure if it should even work theoretically).

When I try to run "make" in a terminal window & also using the ProjectBuilder, I get a whole slew of error messages (posted below). Before running "make", I edit a file called "config.h" (listed below) and put in info like hostname and directory. If I run "make" with the default config.h (listed here), it complies fine. Only when I edit the config.h does it complain. The "make" process doesn't seem to like any field which I remove the hash sign. beginner question: am i correct in thinking that I have to remove the hash sign for any line I want to edit, allowing "make" to 'see'? For example, the default "config.h" has the line: #define HOSTNAME "your.host.edu" which I edited to read: define HOSTNAME "my.host.edu" removing the hash at the beginning of the line so it could be recognized. I'm using NS 3.1 user+developer on Intel. I'm no programmer, and was told to just simply follow the documentation, which i've done! (promise).

What should I do to make the fields validate themselves when the button is hit (i.e. if there is an error, beep and highlight, and return something saying it is wrong so I can return from the set method.) ? I noted another problem too: when my field is valid, it clears itself (i.e. draws white on white) but the text is still here (it comes back is the entry is very long and you scrooll it in the TextField): why?

The problem is, my program tries to get its image before the Workspace has had a chance to finish its housekeeping chores and recognize that an image filter exists out there somewhere. As a result, I end up with nothing. The program works just fine if run from the Workspace after things have settled down. How can I make my application wait until the Workspace has finished with this kinda stuff before it tries to load the image? If this is a really simple question, forgive me.

Obviously you will be the final judge of that. Instead of having it launch from your dock, why not have add it to your Workspace LaunchPaths? This can be easily done with TickleServices, or with a dwrite % dwrite Workspace LaunchPaths "FILE" where 'FILE' stands for the full pathname to the file (and the filename itself, obviously). Separate entries with semicolons, and make sure to use "" around the whole thing. Make sure (before you do this) you check to make sure you don't have anything in you LaunchPaths already. (dread -n LaunchPaths would be one way I guess) If you do, add FILE to them with a semicolon. I believe (99.9% sure) that the Workspace LaunchPaths waits for the Workspace to finish before it goes. This and many other things can be done much easier if you have TickleServices. God Bless Hess!! (ok I got a little carried away with the Thanksgiving spirit) -- Timothy J.

I tried using the above commands and always got an invalid argument error. So, I suspect that they are not supported but I wanted to make sure this is the case. If the above commands are not supported under NEXTSTEP 3.0, are they supported under NEXTSTEP 3.1 or 3.2 ?

Anyways, the first (and more important) is "putenv" In NS 2.1, a version of putenv() is in libcs.a. It may not work quite the way you expect, however! (The source code should be available from CMU.) Generally, a better choice is the widely available BSD setenv() code--especially since NeXT *removed* libcs.a from the distribution beginning with NS 3.0, grr. Actually, it's pretty rare for a program to need to change its own environment--usually the goal is to set up the environment for a subprocess, and execve(2) [or execle(3)] handle that situation far more elegantly. >The other function is "waitpid" -- which should just wait for a specified >process to die before continuing... Any suggestions on doing this also? waitpid() is notoriously nonportable, and you should complain vociferously to the authors that they're being bozos for depending on it.

Many of the objects are palettized for IB. Others have example programs which show their use. See the README file at cs.orst.edu for more details. The new release is version 0.9 Release 2. It adds two new objects, upgrades a few more, and has a lot of other minor changes and bug fixes.

I've chatted with Scott Keith at SofDesign (creators of QuickBase) about this problem. Since I must be concerned about such problems. He has said (as he has told me all along) that they are continuing to work on the DBAdaptor, and plan (relatively soon from what I gather) to release a new DBAdaptor that will fix a number of existing problems, and bring their adaptor more in alignment with the features of the Sybase adaptor. He also mentioned that he wasn't yet aware of this specific problem but would be looking into ASAP.

Anyone know how I can access my custom Attributes >Inspector and Editor? This is a common misunderstanding WRT File's Owner. The problem is that File's Owner is a _placeholder_, not a real object. Basically, File's Owner stands in for the object passed as owner to an Application -loadNib* method. It doesn't actually exist in the .nib file - thus, you can't inspect it (I mean, what is there to inspect?). This has a number of consequences. For instance, File's Owner is created manually via +alloc*/-init instead of -read:/-awake/-finishUnarchiving as .nib objects are created. A reasonable solution that is usable is to have the File's Owner provide an outlet to point at another object which can hold the configuration information. It sounds like a hack, but it really isn't that bad. An alternative solution which I've not tried as of yet would be to make the File's Owner be a simple placeholder which forwards messages to a different object which _really_ controls the .nib file. Since this other object _would_ exist in the .nib file, it can have an inspector.

It sounds *almost* like there are really two questions here. The answer to the obvious one is yes, use -NXHost to redirect the display for an application somewhere else. As long as the receiving system is marked as a public window server, there's no problem. The utility OpenSesame make running apps remotely on severeal different machines an easy task. This acutally has nothing to do with PDO. The other, more subtle thing that will go on (is going on) is "Distributed Objects". These are much more interesting beasts, as they allow an application developer to split up an application in functional units, which can then be run on different machines. Instead of having to manually open a port and send a specific protocol across it, an application will be able to create a proxy object and then from then on simply deal with it as if it were local to the machine it was being run on. The advantage of this over remote displaying is that most of the UI can be run locally, increasing responsiveness to the user for critical UI elements, while the object can be run on whatever machine is best for running that kind of object - say, running a data gathering object on an HP with a disk array. <<A contrived example: you've really gone and site-licensed every Type 1 font in the world and you have them sitting on a server somewhere. It would be faster to have the font object sitting on that server than having it local - such things as getting a list of every font would stay on the server, and only the small portions of the list that need to be displayed in the UI would be shoved over the wire, rather than have every font name shoved.>> In essence, PDOs really do mean that "the network is the computer." Note that either method doesn't care what the processor type is, as long as it's running NEXTSTEP. -- Scott Byer NeXTMail: byer@mv.us.adobe.com Adobe Systems Incorporated These are *my* opinions, and 1585 Charleston Road, P.O.

The operating system is the general controller of the entire computer, or so. When it detects an event, a key press, the mouse moves, a floppy disk is inserted, and so on, the OS determines if the event should be fowarded to the active application. It then put the event in a queue where an application can retreive it (usually the frontmost). The main part of the application is basically a loop that calls a function to see if there is any pending event in the queue that needs to be processed. In NeXTSTEP, all this stuff is hidden from the programmer. For example, if the user clicks a button in a window, the application object processes this event by fowarding it to the window object, which, in turn, will foward it to his first responder. This first responder will have the opportunity to process the event. In short, this is, basically, what is an event driven application. Hope this helps!

Newsgroups: comp.sys.next.programmer From: bouhouch@next.mc.maricopa.edu (Ali Bouhouch) Subject: Debug vs. App compilation discrepancies Message-ID: <1993Nov24.234505.6155@ennews.eas.asu.edu> Keywords: debug, compilation Sender: news@ennews.eas.asu.edu (USENET News System) Organization: Arizona State University Date: Wed, 24 Nov 1993 23:45:05 GMT The following may be a bug in NeXTStep 3.1 for Intel machines. My application works properly when compiled with the 'debug' option selected, but hangs up when compiled with the 'app' option selected. The application launches but hangs up when my controller object is called. Using ProjectBuilder's Debug utility the application runs fine and data looks OK, so the problem could not be located.

It was created specifically to divert lengthy flame wars from .misc. comp.sys.next.announce Announcements of general interest to the NeXT community (new products, FTP submissions, user group meetings, commercial announcements etc.) The NEXTSTEP FAQs are posted here monthly as well. This is a moderated newsgroup, meaning that you can't post to it directly. Submissions should be e-mailed to next-announce@digifix.com where the moderator (Scott Anguish) will screen them for suitability. comp.sys.next.bugs A place to report verifiable bugs in NeXT-supplied software. Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. comp.sys.next.hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. comp.sys.next.marketplace NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. comp.sys.next.misc For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! comp.sys.next.programmer Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. The NEXTSTEP programmer FAQs are posted here. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. comp.sys.next.software This is a place to talk about [third party] software products that run on NEXTSTEP systems. comp.sys.next.sysadmin Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. related Newsgroups comp.soft-sys.nextstep Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. comp.lang.objective-c Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. comp.object Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original comp.sys.next no longer exists--do not attempt to post to it.) Exception to the crossposting restrictions: announcements of usenet RFDs or CFVs, when made by the news.announce.newgroups moderator, may be simultaneously crossposted to all c.s.n.* newsgroups. --------------------------------------------------------------------- Thanks to Michael Ross at antigone.com, the main NEXTSTEP groups are now available as a mailing list digest as well. next-nextstep-d next-advocacy-d next-announce-d next-bugs-d next-hardware-d next-marketplace-d next-misc-d next-programmer-d next-software-d next-sysadmin-d (For a full description, send mail saying LISTS to <digestif@antigone.com>).

You don't know when something will arrive, but you need to be able to handle it when it happens. Somewhere during initialization you set up your socket. Then you call this. - initMessages: aSocket { extern void myMsgHandler(); DPSAddFD(aSocket, myMsgHandler, (void *) self, PRIORITY); } /* Heres the handler which could do the work itself but in this ** case will convert it into a message to send to an object. *. void myMsgHandler(int fd, void *userdata) { id recipient = userdata; [ recipient readMessage: fd ]; } What you have done here is to associate a file descriptor with an object responsible for reading it when something arrives. Whenever the event occurs, the handler gets called and you end up passing a message to the appropriate object, which causes the socket to be read (or accept()ed etc.). Thus you have defined a new application specific event: what needs to happen when input arrives on this socket. Really, an application specific event is simply a *system* event or class of *system* events to which you have ascribed an application specific meaning. -- ___ ___ mail: uunet!phcs!jq PHCS, Inc.

Threads is a very important facility. Distributed Objects, for example, relies on them - [NXPort worryAboutPortInvalidation], for example, which spawns a new thread to listen for port deaths. Will OpenStep include specifications for a threads (pthreads? cthreads?) implementation? Will the NEXTSTEP spec change to become a superset of OpenStep (removing mach dependencies from the developer kit interfaces)?

The error you made here is to think tha the .h file will be read by make. It won't (in most cases). A name.h (or name.m, name.c, for that matter) will be read by the C compiler that is invoked by make. The programs use different Syntax. In C, a comment starts with "/*" and ends with "*/". In makefiles, comments start with "#" and end with a line break. C uses the hash to mark Preprocessor commands in C. Make has some file-timestamp - based rules on when to "see" files, plus the non-comment lines in the makefile. Thus, make will "see" your config.h once it's newer than the file you want as the result of the compilation (and if it's listed correctly in the makefile you got, what youu should be able to count on). The C compiler still counts on the #. #define ID "text" tells C to replace instances of "ID" with ""text"" (including the inner quotes). define ID "text" makes no particular sense, but could be read as: Create a variable with Name ID and type define, then choke on "text". Which may explain some of the errors. -- Felix (fxg@(([Pool|I3].Informatik)|(Tolkien.ImIB)).RWTH-Aachen.de NeXT-Mail ok, but slow)

So here's some peculiar behavior that I don't ever remember seeing before in 3.0 (or earlier): I've built an App which has a 'Plot' button to read a file for some numbers and then make a plot from them. It runs fine in GDB when entered after building it by clicking the 'Debug' icon in the PB interface. Likewise, it runs fine by building with 'make' from a C-shell command line, followed by 'MyApp.app/MyApp'. The 'Plot' button doess what it should and the plot stays around afterwards for me to look at. HOWEVER, if I build the App by clicking the PB's 'Run' icon, the App launches OK. And, clicking on other buttons (I also have a 'Clear' button), nothing unexpected happens. But, clicking on my 'Plot' button now immediately wipes out the App's window from the screen. I can't find any error messages in the Console window or private/adm that pertain to this. I've also checked (and don't believe) that I'm writing beyond some array's limits. (Suspecting a bus error, there.) Has anyone else seen anything like this? And, without looking at any of my (54-line) code, have any idea what might be going on? Dick Silbar WhistleSoft, Inc.

I'm just speculating here, but I think that changing the imaging model would remove a great deal of the benefit of having OpenStep in the first place. Say you have a subclass of View in your application (which carefully avoids operating-system-specific calls) which plots a graph in its -drawSelf: method. The only way to recompile this Object under OpenStep would be if all three of the following are present: AppKit's View superclass Objective-C Display PostScript with wraps The way I see it, those are the minimal features, and DBKit and Distributed Objects are icing on the cake to make OpenStep even more tasty. If Display PostScript wraps and single operator calls were not such an integral part of most people's existing custom UI objects, then allowing for different imaging models might make some sense (just like ignoring the underlying OS makes sense for *most* Objects). To remove DPS would require the invention of some other abstract imaging model that could be translated to DPS, Quickdraw, X Windows, or (gasp) GDI on the target system. P.S.

Well, it has a very simple explanation, as pointed out to me by Ray Spaulding of Georgia Tech: I believe the current working directory will be different depending on how the app is launched -- it will be your project directory under debug, but your $HOME directory under a workspace launch. Perhaps your "Plot" method is unable to find the data file and killing the app. Unfortunately, I already knew something like that, but it didn't occur to me in the present context!

I think the point is that the API -includes- PostScript constructs as part of its specification: i.e., pswraps, fonts, and window contexts (not to mention PS and DPS function calls) can all be used by OpenStep programs. Of course that just means the Display PostScript 'spec' is part of the API, and the implementation can vary. However, I do not think any of the other imaging models is capable of simulating Display PostScript (nor, for that matter, is GhostScript). I have no idea how much effort it would be to emulate all of DPS (fonts, contexts, coordinate transforms, etc.), but I suspect it is non-trivial enough that all commercial implementations will just license it from Adobe (if they haven't already). -- Ernie P. -- Ernest N.

This is an important issue in our group, which has an HP-755 providing X to a mixed bag of a couple dozen macs, half a dozen SGIs, several X terminals, and a handful of PeeCees and NeXTs. It'd be impossible to wean them of X overnight. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .Dr. Robert F.

This exact thing happened to me once, and I never figured out quite why. I was programing a dumb "vector-ball" demo as an example for a class. Well, the vector balls worked alright--but the damn thing would only run from the command line! (it also would fail if you double-clicked it from Workspace). The only thing I can say is that you might want to check the way you're calling [super initFrame: ] or something like that. I don't know if that's even close, since it works fine for me everywhere else. To be honest, I haven't looked at the problematic code in many moons... If anyone else has a clue why this might happen, I'd like to know as well :) Mike Fleming > Dick Silbar > WhistleSoft, Inc.

I happen to be reading a book on programming with the Mach system, which is not necessarily what you are looking for, but might be of interest: Programming Under Mach, by Joseph Boykin, David Kirschen, Alan Langerman, Susan LoVerso. 1993. Publ: Addison-Wesley. ISBN: 0-201-52739-1 The book discusses Mach concepts under Mach 2.5 (mostly) and 3.0. It is oriented toward getting a programmer up to speed using those Mach fundamentals of threads, tasks, IPC, virtual memory, C threads, exception handling, the Mach Interface Generator, and more. The book covers the philosophy of various Mach features and lists specific code to illustrate concepts. I know next to nothing about Mach, which is why I am reading the book, but I do find the book quite understandable and well written. It explains threads and IPC better than anything else I have read. I would appreciate the opinion of someone more expert in these matters on the value of this book (or any other Mach book, for that matter.) -- Kevin Jim (jim@galileo.ifa.hawaii.edu)

It's one of THE NeXTstep strong points to have a powerful and general graphics API. Look ad Quickdraw: That was Apple's imaging model. DTP got huge with the PS imaging model! Applications had to draw on the screen with the quickdraw API and printed with PS code. That's still reasonable, because PS seems to be a superset of all other rendering mechanisms in use today. Look at the *2ps converters out there. The back route is much harder. You won't come short of a RIP for any conversion worth the trouble. So why rewrite all apps under NeXTstep? I doubt that any algorithmic solution would be useful. So what would be a vendor-independant Graphics API anyway? Your'e just substituting Vendor Adobe with Vendor Bedobe. Or even a Consortium?

This exceeds the maximum allowable size of a row in a table, 2014." My tables are modest (?) -- only approx 30 columns, mostly null entries for now, though a few are IMAGE or TEXT. While I can't say anything about Szbase in particular, I can say some things about INGRES that may very well apply to Sybase also: Q0. Does "row size" mean total number bytes filled by actual data? Well, in a way, yes. Logically, all fields in the table are filled up to their size given in the declaration with "actual data". These data include padding spaces that are added when you enter shorter data into the DB. It may not look like actual data to you, but for the DB system, it very well is. Q1. What is the "work table"? Where is this documented? Any retrievel retrieves values from a DB. But where is it to store them? An application may put them into scroll views or whatever IT deals with, but the DB deals with tables. So it puts the data into temporary tables. These may be the work tables, just as well as those that are used when a join is evaluated. Q2. How can I increase the row size ceiling? I'm afraid you can't. At least not in INGRES. It handles data in physical 2k - pages, minus some adminitration bytes, leaving, I think, 2008 Bytes to the user. And a row can't span several pages. Another hard limit seems to be 30 columns per table. You can get around this with BLOB-type things. BLOB is for Binary Large OBject. These won't generally be stored in the DB table itself, but in seperate files, with a pointer of some small kind in the table. As I said, I don't know if these exacxt restrictions apply to Sybase also, I especially don't know about an IMAGE type, which sounds like an BLOB type.

Date: 29 Nov 1993 18:58:31 GMT Organization: University of Houston Message-ID: <2ddgon$rg0@menudo.uh.edu> Hi, I am doing a project on the NeXT, but the question I have is very much in the basic "grassroots" C. I have posted this in comp.lang.c, but no replies, so I am trying my luck here :-). I am building a user-interface, and am using someone else's object to do some parsing of strings which will be entered by the user while running my program. Now, the object ( lets call it Expression) maintains a list of functions which it can parse for. I don't know how it works, but it works very well. Expression also has a method with which I can add new functions to this list. All is nice when I know the functions which I want to add to the list before hand. I can just add a few lines to the code and I am done - Expression will now recognize the new function. The problem is that I want to do this runtime. So the user will enter the name of the function he wants added to the list in a window, and I want the parser to recognize the function. I can specify that the new function to be added to the list be entered in a specific file, which will be compiled along with my program. So the compiler will "know" the new function at compile time. I cannot obviously maintain a list of function pointers and function names, before hand since 1. The function names will be known only at run-time. 2. I will not know the address of the new function. I hope I have put my problem accross clearly. Any help would be greatly appreciated. -- Rama Rao Pakala, Systems Design Laboratory, W224-D3, College of Engineering, University of Houston ******************************************* To be is to do - Immanuel Kant To do is to be - Sigmund Freud Dooby, dooby, do - Frank Sinatra

Among this object's instance variables are things like: id target; SEL action; id errorTarget; SEL errorAction; The `action' method is sent to the `target' when new data arrive from the front-end processor. The `errorAction' method is sent to the `errorTarget' when communications with the front-end processor breaks down. There are associated methods like: - setTarget:target; - target; - setAction:(SEL)action; - (SEL)action; - setErrorTarget:target; - errorTarget; - setErrorAction:(SEL)action; - (SEL)errorAction; I'd like to be able to make the connections to this object using the Interface Builder. For the `target' and `errorTarget' instance variables this is no problem -- the names appear in the Outlets column of the IB CustomObject Inspector connections panel. The Actions column is blank, though. I want to make the actions connectable, too (like it is for things like buttons). How do I do this? My object is now a subclass of Object. If I made it a subclass of some other object (Cell?, Control?) would the Interface Builder do what I want? Do I have to write some sort of Inspector for my object?

My bet is that your tiff file isn't part of your nib/project. Look in the Images suitcase in Interface Builder. If your icons aren't there, drag them in, Interface Builder will then ask you if you want to insert them into your project. If the icons are in the interface builder suitcase, try adding them to the Images section of project builder.

Unfortunately, the question they answered wasn't the one I intended to ask. I see that my question wasn't worded clearly enought. I don't want to set up connections *to* my custom object, I want to set up connections *from* it. Perhaps the following example can make things clearer. I have an class (HexComm) with instance variables like: id target; SEL action; id errorTarget; SEL errorAction; I instantiate an object of this class in the Interface Builder window. Let's say I call this instance hexCommObj. I want to set up the connections from this object (hexCommObj) to some other object (let's call it dataHandler). The dataHandler object has methods like `- handleData:sender' and `- handleError:sender'. To make the connections I control drag from the hexCommObj sphere in the Objects window to the dataHandler sphere in the Objects window. What I see in the inspector window at this point is: +---------------------------------------------------+ | CustomObject Inspector | +---------------------------------------------------+ | | Connections *| | +---------------------------------------------------+ | Outlets | | +---------------------------------------------------+ | target | | | errorTarget | | | | | | | | So, I can set hexCommObj's `target' and `errorTarget' instance variables to my `dataHandler' object, but I can't set the action or errorAction instance variables. What I *want* to see in the inspector window is the sort of thing you see when you control-drag from a button. i.e. I want to see something like this: +---------------------------------------------------+ | CustomObject Inspector | +---------------------------------------------------+ | | Connections *| | +---------------------------------------------------+ | Outlets | Actions | +---------------------------------------------------+ | target > | list of possible | | errorTarget > | receiver actions in | | | dataHandler object | | | | Note that the `target' outlet now has a little right-arrow beside it........ I can see why this can't ``just work'' (how does IB know that target and action go together, and that errorTarget and errorAction go together?), but I hope there is some reasonably simple way of doing this. -- Eric Norum eric@skatter.usask.ca Saskatchewan Accelerator Laboratory University of Saskatchewan Saskatoon, Canada.

As to the main topic: I think that we should start a campaign to urge NeXT to buy a Cygnus maintenance contract. If NeXT would pay Cygnus (or any other qualified party) to maintain all of the GNU software on the NeXTSTEP platform, NeXT could divert resources from maintaining Unix utilties to writing device drivers, object kits and doing an SGI, PowerPC and Alpha port. There is really no reason why we should be stuck with some partially braindead BSD tools, when there are sometimes vastly superior GNU versions available. It also does not make sense to install all tools twice (once in /usr/local/gnu/bin and once in /bin or /usr/bin), nor does it make sense that NeXT wastes manpower and resources in maintaining old tools. If they were to send some money and equippment to Cygnus, we'd get source, support and better tools. NeXT would free resources to do more "mission critical" work on NeXTSTEP... Hey, and maybe we'd even get NeXTSTEP interfaces to some of the GNU tools. e.g. a "railway" diagram editor for yacc/byacc/bison etc. :-) -- Ronald ============================================================================== "The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.

An application-defined event is something your own application can post on the normal event queue so that it is dispatched automatically when it is encountered in the event queue. For instance, I needed to have a server shut itself down when it received a SHUTDOWN message. I was able to use distributed objects to have a client administrator application connect to the server and send the shutdown message. However, in the server, my original thought was to just do the shutdown when the server got the shutdown message. Unfortunately, there may be other events waiting to be processed that arrive after the shutdown arrives but before it is handled. The proper solution in the shutdown method is to "quiesce" the server (i.e., turn off its ability to receive new messages), post an application-defined event (so that it will be the last event in the queue) and then let things wind up properly. No new messages will be accepted but already received messages will be handled normally. When the application-defined event gets its turn, there should be no more events in the queue to process.

I don't think I've seen this one, however. I'm trying to build an App which provides a front end to a Fortran source code. (I didn't write the code and have only modified it very slightly to fit the App.) I've certainly done this sort of thing before, when on black hardware, and thus anticipated no troubles. My Fortran "compiler" is the f2c converter. I might add that I recompiled f2c myself to run on the NS/I 3.1 machine I'm now using. Don't recall there was any problem here other than having to define CRAY (cc -DCRAY ...) to avoid a few multiple definitions. And, the f2c works. Compiling the Fortran code with the provided 'f77' script, f77 -g -o sola sola.f [no kidding, that's its name. Really.] and having the libraries libF77.a and libI77.a in the right place, /usr/lib/, sola reproduced test example results (originally run on a CRAY back in the 70's) down to the last visible significant digit in many, many numbers. (It is a 2D hydrodynamics code.) No complaints during the compilation process at all. What _doesn't_ work is when I do the compilation and loading while building the App in Project Builder: f77 -c -g sola.f sola.f: sola: cc -g -O -Wall -I./sym -arch i386 -ObjC -sectcreate __ICON __header Sola-2DFlow.iconheader -segprot __ICON r r -sectcreate __ICON app /usr/lib/NextStep/Workspace.app/application.tiff -o Sola-2DFlow.app/Sola-2DFlow i386_obj/SolaController.o i386_obj/VecFieldView.o i386_obj/Sola-2DFlow_main.o i386_obj/drawVector.o sola.o -lF77 -lI77 -lMedia_s -lNeXT_s ld: Undefined symbols: _sig_die *** Exit 1 Stop. So, the loader can't find something called _sig_die. But _sig_die *IS* present in the libF77.a library. You can see it there as a sig_die.c file before you make the library, as a sig_die.o relocatable, AND as _sig_die in the libF77.a symbol table. (At least, I THINK that is the symbol table, up there at the top of the libF77.a file; in any case the string "_sig_die" certainly appears about four times in it.) It appears there are no other symbols the loader can't resolve. (There were plenty, before I got the libraries inserted in the Project Builder.) Does this make any sense to anyone? I'm (once again) baffled. Thanks in advance, Dick Silbar WhistleSoft, Inc.

I am a partner in a small record label and we are in the process of setting up our UUCP/News connection. When everything is finished, we would ideally like to be able to have email sent to us which, depending on the contents of the subject line, automatically replies. For example, if someone send us a message with the subject reading: bio Siddal, this would automatically send a (non-NeXTmail) reply containing the bio for our band, Siddal. Catalogs, order-forms, press releases, indexes, song lyrics, etc. could all be retrieved this way. I realizes this is no small undertaking, but I have had quite a bit on Unix experience and am now learning to develop using NEXTSTEP. Has anyone here set-up something like this? I'm not looking for someone to write it for me, just to point me in the right direction in way of books and other reference materials. Thank you very much for your time and help!

It was created specifically to divert lengthy flame wars from .misc. comp.sys.next.announce Announcements of general interest to the NeXT community (new products, FTP submissions, user group meetings, commercial announcements etc.) The NEXTSTEP FAQs are posted here monthly as well. This is a moderated newsgroup, meaning that you can't post to it directly. Submissions should be e-mailed to next-announce@digifix.com where the moderator (Scott Anguish) will screen them for suitability. comp.sys.next.bugs A place to report verifiable bugs in NeXT-supplied software. Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. comp.sys.next.hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. comp.sys.next.marketplace NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. comp.sys.next.misc For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! comp.sys.next.programmer Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. The NEXTSTEP programmer FAQs are posted here. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. comp.sys.next.software This is a place to talk about [third party] software products that run on NEXTSTEP systems. comp.sys.next.sysadmin Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. related Newsgroups comp.soft-sys.nextstep Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. comp.lang.objective-c Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. comp.object Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original comp.sys.next no longer exists--do not attempt to post to it.)

The same thing will happen with the other objects, because they use the DBFetchgroup, DBRecordList, DBBinder, DBQualifier and DBValue classes. Has already someone contact NeXT with similar problems.

I have a lot of other problems: - how to get a fetchgroup to save all properties of a 1/1 join(I think I will just build views); - how to determine to which table and column a key property in a view belongs. think I will make the restrictions, that these dependencies have to be entered in a different table. The only solution I had in mind was to get the view definition with sp_helptext out of Sybase and perform a parsing of the text (its a recursive operation, because views can be build on top of views).

The devil will be in the details, but I think Ernest is right about the DPS part. I suppose it would be possible to divorce NEXTSTEP from DPS at the API level, but if you're going to do that, you might as well rewrite NEXTSTEP from scratch. It would probably be less work to write a DPS clone. It remains to be seen just how hard porting from NEXTSTEP 3.X to OpenStep is going to be. The "operating system independent portions of the API" is practically meaningless in a world where most people consider "fopen" and "bcopy" to be part of the OS! Here's my guess at what the OpenStep API will be: All of /usr/include (particularly appkit, dbkit, dpsclient, and objc), except that bsd/* and mach*/* are replaced by equivalents in POSIX.1 or SVID or CDE or DCE. For example, I'd expect all the stdio.h/stdc.h stuff to come from POSIX.1, the RPC stuff to come from DCE, the network stuff to come from SVID, etc. Ports and messaging will probably be abstracted, or omitted entirely in favor of using the higher level abstraction of DO and PDO. cthreads could be replaced by pthreads, or could become a higher level abstraction. In terms of user level features, I'd expect NEXTIME and RenderMan to be omitted, but everything else that we know and love should be there. It's possible that NeXT will do something similar to Microsoft's Win32, Win32s, and Win32c. That is, NEXTSTEP 3.2 (Win32) is the superset API, in which there already exists an OS-independent subset (Win32s) which will form the basis for OpenStep. NEXTSTEP 3.3 (Win32(Win32c)) will add some abstractions so that programs targeted for OpenStep will compile and run on both flavors. I wonder if they'll do an ABI as well, so that native SPARC NEXTSTEP 3.2++ will just run on SPARC OpenStep, and vice versa. If OpenStep is to run on Solaris, this probably won't happen (MAB ELF?

I will enlcose the list of books that have at least a sizeable chapter on Mach internals. Mary Thompson Mach Project Distribution Manager Date: Oct. 1993 Abstract: Books containing substantial information about Mach -------------------------------------------------------- Programming Under Mach Joseph Boykin, David Kirschen, Alan Langerman, Susan LoVerso Addison-Wesley Publishing Co,. 1993 481 pages This is certainly the most complete presentation of how to program applications using Mach features. It explains the basic Mach abstractions of tasks, threads, ports, messages and memory objects and gives examples of why and how to use them. There are introductory chapters for tasks/threads, interprocess communication (IPC) and virutal memory. Following this are chapters on advanced features of IPC such as server processes might need, the Mach Interface Generator which is used to simplify the writing of IPC interfaces, and external memory management. There is also a chapter each for C-threads and OSF/1 P-threads, and the Mach exception handling facility. There are frequent short code examples as well as a complete client/server example of an external memory manager. The code is all compatible with Mach 2.5, but references are made to where there are differences with Mach 3.0. Even if your goal is to program for a Mach 3.0 system, this book is a good place to start since the basic concepts have not changed significantly. Once the basic ideas are understood, the Mach 3.0 reference manuals can be used to update your knowledge of the details. -------------------------------------------------------- Distributed Operating Systems: The Logical Design A. Goscinski Addison-Wesley Publishers., 1991 Chapter 14.8, pages 864-888 is about Mach This is a subsection of a chapter surveying seven experimental distributed operating systems. It defines the basic Mach abstractions and goals. It emphasizes the software architecture both at the high level of the system tasks running on tightly coupled multi-processor platforms or a network of loosely coupled machines and at the implementation level of describing the various kernel modules and data structures. Specific primitives are specified and an outline of a client/server shared memory server is given. ------------------------------------------------ Advanced Computer Architecture: Parallelism, Scalability, Programmability K. Hwang McGraw-Hills, Inc., 1993, pages 686-709 --------------------------------------------------------- CMU Computer Science - A 25th Aniversary Commemorative Ed. R. Rashid Mach: A Case Study in Technology Transfer - Chapter 17 pages 411-421 ACM Press, Anthology Series, 1991 This chapter describes history of the Mach operating system research project and its efforts to transfer the ideas imbedded in that system from the research laboratory to industry. --------------------------------------------------------- Operating Systems Concepts A. Silberschatz, J.L Peterson, P.B. Galvin Addison-Wesley Publishing Company, 3rd Edition 1991 Chapter 16, pages 597-628 is about Mach. Gives a brief introduction to Mach, its history and design goals. Covers the basic concepts of Mach, its similarities and differences from Unix. Discusses the NetMessage Server and how it extends IPC trasparently across machines. Covers virtual memory managment and external memory managers and sharing of memory between tasks. There is a brief mention of implementation details and how they compare with BSD-Unix. ------------------------------------------------------- Modern Operating Systems Andrew S. Tanenbaum Prentice Hall 1992 Chapter 15, pages 637-682 (Case Study 4) is about Mach This chapter gives a general introduction to the Mach 3.0 micro-kernel and compares it to the Amobea operating system. Implementation of task and thread creation and scheduling are covered in some depth as is memory management and interprocess communication. External memory management is explained and there is a brief description of the Network Message Server and the Unix server. ------------------------------------------------------- Mach: Konzepte und Programmierung Christoph Zimmermann, Albrecht W. Kraas Springer-Verlag, 1993 192 pages, written in German This book coveers the concepts and programming interfaces of the Mach kernel. It addresses both the novice and the more advanced reader. The first part reviews the reader's knowledge of operating systems, and introduces the basic Mach abstactions of VM objects, threads, tasks, etc.. The second part presents an in-depth description of the following topics: Mach IPC, the MiG, Cthreads, the Mach VM system, the External Memory Management Interface (EMMI). An application example gives this section on Mach programing a final polish. An outlook in the last chapter presents the differences between the 2.5 version of Mach and the Micro-kernel based 3.0 version together with the description of the Unix-Emulation.

Oei pty support by Joe Freeman Subprocess Example, Release 2.0 NeXT Computer, Inc. distributed with NS3.1/Motorola, compiled and run under NS 3.1. Good behavior: 1. Launch MyShell.app from workspace. 2. Type exit after $ prompt. What happens: As subprocess exits, DPS invokes fdHandler, we get into -[Subprocess fdHandler:], bufferCount<0 => we get into -[Subprocess childDidExit], and the Subprocess delegate gets subprocessDone message. BAD behavior: Start by logging in. Let define N to be 4. (If you cannot reproduce behavior below, just increase N and eventually you will be able to reproduce it.) 1. Launch MyShell.app. 2. Launch N-1 more MyShell.app copies (Alt-double-click). 3. In the N-th running copy of MyShell.app type exit after $ prompt. What happens: Subprocess exits (one can verify this by doing `ps ux|grep sh' in a Terminal window before and after typing exit), but the Subprocess delegate does NOT get subprocessDone message! (DPS does not invoke fdHandler.) More BAD behavior: 1. Open M<N Terminal windows in Terminal.app. 2. Now you just need to run roughly N-M copies of MyShell.app to get the bad behavior. 1. If the Subprocess object is used in an app which runs N Subprocesses, we get the bad behavior (no exit notification).

I assume the invalid argument isn't NULL, but my understanding of what goes on in ioctl isn't great. If I remember right DKIOCCHECKINSERT is #defined as _IO('d', 26) if that makes a difference. This is similar to the #definition of DKIOCEJECT, therefore the NULL argument seems reasonable. Can anyone help me out with this? All I want to do is see if there is in fact a disk in the drive. I tried doing this with a test-unit-ready scsi command but for some reason, even with a 1 second timeout, this check takes about five seconds with a disk check about once every second.

It makes no sense to say that. RenderMan is a "scene description language", it is, by definition, an API. Why would you expect it to go away, especially given that NeXT and Pixar are a bit more connected than NeXT and Adobe. It's not very hard to write a renderer that sticks to the RenderMan spec (i.e. takes all the RiXXX() calls) and makes calls to, say, OpenGL. This doesn't mean that you can display to the screen exactly what the final .rib file would look like, but so what? Save it out as .rib and render it somewhere else, same way you take your .ps file to service bureau. I would be very, very, very surprised if the 3DKit, based on the RenderMan API, went away in OpenStep. It's one of the easier parts--just do a qrman implementation that talks to OpenGL.

Perhaps, I will write about it sometime. There are two pretty unique features that I particularly like which I would like to see incorporated in other NEXTSTEP apps. So, let me state what they are so more developers will implement them. [1] Multiple Views into a single document. All apps I have seen let you see and manipulate a document in one view/window at a time. E.g., you have to zoom in to see details and zoom out to see the whole picture, and often zoom/unzoom is a time consuming operation. Tailor lets you see a single document via multiple views in separate windows, e.g., one zoomed, another unzoomed, and yet another showing a different section. This may not always be needed and you don't have to, but it's great to have the capability when you can really use it. I really want this feature in Edit.app. If someone writes a better Edit with multiple views into a single document, I will buy it. (Don't tell me emacs can do this. It doesn't count.) [2] Entering Groups without Ungrouping. In all drawing apps I have used, in order to edit members of a grouped object, you have to ungroup it first. Tailor lets you "enter" a group and let you edit its members without breaking the grouping. I want to see that in Virtuoso and other apps.

But on intel boxes, the first recording attempt after the program launches results in zero bytes recorded. Is there some flag that needs to be set to wake up the sound driver? 2) Updating information like peak samples in an NXSoundStream or NXSoundDevice is VERY VERY slow--about 2 updates a second. Perhaps this is just the nature of sound hardware without a DSP and custom DACs, but I was wondering if there's a way to get this very fast machine to dedicate more resources to these kinds of updates... 3) The SoundView suffers from a variety of ailments, including bizarre sound display which I think stems from big-little-endian problems. It appears that sounds store their sound information only in big-endian format, and convert the sound when playing out, and this sometimes confuses a SoundView which has been compiled to deal with little-endian formats. 4) While we're on the subject of big-little-endian stupidity, the big-endian bug bites big in my custom modules, most of which mathematically adjust the sound. Since _they've_ been compiled for intel, they too expect the sound data to be little-endian. As a result, simple programs like a sine wave generator produce astonishingly strange amounts of noise instead of a sine wave. 5) Some conversions using NeXT's conversion functions not only don't work in NS/I, they *bomb* the machine! Of course, none of these problems exists in the Black version of my software, which may force me to only release it in Black. I'd hate to do this. Can anyone help? Discounting the bugs, I'd like to know at least if there are functions which 1) Indicate if I'm on big- or little-endian hardware, and 2) Convert chars, shorts, ints, longs, floats, and doubles to big- or little- endian formats. Even if I can't fix (perceived) errors in the Sound Kit, at least I might be able to deal with the endianness in my own code. Can anyone help here?

The documented way to do this is to do a 'rollback transaction' and then a 'raiserror xxx "text"'. The problem with this method is that when the condition fails and the trigger rolls back the transaction, the raiserror comes through the Sybase adapter as a message in an alert panel, but does not cause the delete operation to fail. Because the delete didn't fail, DBKit then attempts to commit the transaction which does fail because the transaction has already been rolled back. When the commit fails, a rollback is attempted which also fails. Each of these causes another alert panel to pop up informing the user of the problem. Here is a description of what I'm doing on the NeXT side. I have a DBModule with several properties connected to vectors in one DBTableView. There are buttons connected to the -deleteRecord: and -saveChanges: methods of the DBModule. When a record that fails the above condition is deleted and then saved, the following sequence of events occurs: 1) Alert panel: Database Sybase server: <server name> Procedure: delete_business_area Line:7 Message: This business area is in use. 2) Alert panel: Database Sybase server: <server> Procedure: none Line: 1 Message: The commit transaction request has no corresponding BEGIN TRANSACTION. 3) Alert panel: Database Sybase server: <server> Procedure: none Line: 1 Message The rollback transaction request has no corresponding BEGIN TRANSACTION. 4) The DBTableView does not show the record that was attempted to be deleted. It behaves as if the delete succeeded. Also, at no time was the -fetchGroup:willFailForReason: method of the DBModule's delegate ever called. This would lead me to the conclusion that as far as DBKit is concerned, the transaction succeeded. How can one inform DBKit that the transaction failed and has been rolled back? (I need the rollback transaction in the trigger for situations when sources other than DBKit initiate the delete.) Is there a particular error number that should be used in the raiserror or another Sybase function that will do the job? Thanks in advance... Eric S.

On Intel this will yield 0.0. But NEXTSTEP doesn't return this from messages to a nil object. It returns NaN if interpreted as a float. (Note that all messages to nil return exactly the same thing, since no actual instance method can be invoked. I suppose the selector could be looked up to determine the appropriate return type, but that would be expensive. Besides it isn't *required* by the runtime that all classes have the same return type for a given selector (though it is certainly recommended.)

[stuff deleted] It looks like the real problem is that the register used to hold floating point return values is not getting zeroed out by objc_msgSend (or whatever it's called) when it sees a message being sent to a nil object. It doesn't really need to be any more complicated than that. Moreover, I suspect that objc_msgSend is coded in assembly language for NS/I (as it is for NS/68k) and this necessity was somehow overlooked. This would be a 1 instruction fix. Also, if necessary, any other return values stored in registers should get zeroed here as well (it appears as though (id) and (int) returns are already handled appropriately). I'm sure the right folks could make quick work of this, assuming some one filed a bug report (instead of just net.gripping (I'm not saying that's what happened, just that you shouldn't expect something to get fixed if it hasn't been reported).

It's so close but I've got one little problem: I can't get the data I've collected out of the driver. It's a driver for a data aquisition board, so it operates not by requesting data, but instead you configure and arm the board for external triggers. When an external trigger triggers the board it collects data at which point I need to have the driver send it to the user level program which is controlling the board. I think the only logical way to do this is through a mach port. The problem is I can't figure out how to establish a port connection between a kernel(driver)task and a user task. Here are somethings I've found out so far: - I can't find any driverKit functions to do this - I've tried to get the driver to register a port with "netname_check_in" but it can't find "name_server_port" so it won't compile. And if I include <mach/mach.h> the header definitions conflict with some driverkit headers. - Loadable Kernel Servers (LKS), which the driver kit is a super set of, allow ports to be ADVERTISED by specifying in as a Load Command (appendix A in the writing LKS's manual section) It would make sense to me to have the IODevice and IODeviceMaster be able to establish mach ports between the kernel driver and the user level tasks using the driver with the IODeviceMaster object. Maybe in 3.3. Thanks for any help (please email responses) Michael Haker dept chemistry, UW-Madison haker@whitewater.chem.wisc.edu

No flame intended, just trying to make a point). That's fine, but to add a little information you might not have known about, at the Developer's conference at the last NeWXTWORLD Expo, it was explicitly stated that any message to nil will return nil for methods that return ids, but that any other return type is unpredictable. Period. They called it "luck" that ints return zero in Intel hardware... So the implication is that NeXT knows about the problem and not only plans to _never_fix_it_ but also, they will create even more inconsistencies in the future with their newer ports. In other words, NEVER rely upon a message to nil to return a zero. Instead, you should code stuff like this: (anObject ? [anObject floatValue] : 0.0 ) or you can make some macros for your project's main header file: #define FLOATMESSAGE(a, b) ((a) ? [(a) b] : 0.0) #define INTMESSAGE(a, b) ((a) ? [(a) b] : 0) and so on... and then as new ports come out, you don't have to worry about this problem, since you've planned ahead for chaos... Seems to me this is extra code that should be handled from the runtime, as you suggest, but apparently NeXT doesn't want to do this. So, as you say, it's something to lobby for. But it would be classified as a feature request, not a bug fix, given the attitude NeXT has shown on this topic. I think this extra code should not be necessary; but the NeXT engineers said that it should be considered an error to send a float-returning message to nil...so in my code, for robustness, I basically use the above construct to trap all places where these problems might occur in the code. Since I basically do this for every message, it seems to make more sense to put it in the runtime system, since the overhead will be lower if it's put there. Now, to convince NeXT that it is worth doing and that it is what we want... -- Don_Yacktman@byu.edu Nepotism is a relative thing.

If I use the IP address of george as the host machine, the login windows disappears for about 5 seconds and then beeps at me. All of the parameters in the login window were entered correctly. I dumped all of the packets between the server and the NextStep machine and noticed that whenever I used the domain name, the NextStep machine doesn't send any packets to the server in trying to connect to the database.

Is there a particular > error number that should be used in the raiserror or another Sybase > function that will do the job? I asked NeXT about this problem several months ago and received the attached response. Note that transactionDidRollback is an undocumented DBDatabase method, so use accordingly. I'm not sure whether 3.2 is required for this to work properly, but NeXT made significant changes to the 3.2 Sybase adaptor which might affect this process. Another problem that probably hasn't been fixed in 3.2 is that when a trigger prevents the update of a record, the fetchgroup isn't made aware that the save failed so the fetchgroup erroneously answers "NO" to hasUnsavedChanges :-( So the recordlist is now out of sync with the data in the database. The only way to resync appears to be to delete the record or to refetch the data, neither of which is a very nice solution. Note that for the purpose of this attached example, my trigger calls raiserror with an error number of 25100. The place to trace a Sybase trigger raise error is in the method db: notificationFrom:message:code:, and not inside fetchGroup:willFailForReason:. This will be better documented (as a NextAnswer) and in the Release Notes too. For now, I have added the code below to your test case: - (BOOL)db:aDb notificationFrom:anObject message:(const unsigned char *)message code:(int)code { fprintf(stderr, "(%d) %s\n", code, message); /* If the error code is the trigger raiseerror, tell * the database object that the trigger has rolled back * the transaction. This will sync up DBKit which will no longer * try to rollback a transaction because of the error situation. */ if ( code == 25100) [aDb transactionDidRollback]; return YES; } When the trigger fires, the trigger error will be raised and you'll see the error as follows: (25100) Sybase Server:unknown Procedure:t1_i Line:8 Message: Invalid value for c1 Then, the database object notifies the adaptor that a transaction has rolled back. Again, this is the programmer's responsibility to know that he has rolled back the transaction inside his sybase trigger. If the trigger doesn't roll back the transaction, the programmer could add if ( code == 25100) [aDb rollbackTransaction]; to roll back the transaction at the application level. Now, things must be in sync. -- Art Isbell Cubic Solutions NeXT Registered Developer NEXTSTEP software development and consulting NeXTmail: art@cubicsol.com Voice: +1 408 335 1154 USmail: 95018-9442 Fax: +1 408 335 2515

It should configure and build itself. At least under NS3.1 it does. (2) Will emacs v. 19 break Emacs.app? In some unpatched older versions of Emacs.app there is a bug which will give you an unnecessary query every time you try to quit Emacs.app but apart from that there should be no problems. And before anyone asks: Emacs 19 for NS is in alpha test right now and the testers seem to like it. There still are a few features which need to be added/completed (automatic use of NS menus to emulate Emacs menus, support for foreign character sets, documentation), so there is no public release yet, but there will be one as soon as I get around to finishing them.

Actually, I was missing a whole array of good features that are activated with Alt, Shift, Control keys with mouse ops. Better read the FM sometime. However, it doesn't seem possible to add a new object into a group, i.e., not everything you can do outside a group can be done into grouped objects in Virtuoso.

Well, this seems to be a programming technique issue here. What do you expect to get from a nil object? "ex nihilo nil fit" is neatly fitting here: from nothing comes nothing. IMHO, the second nothing should be read as "undefined". So I don't really object to this kind of behaviour / design decision. Make sure you're not talking to nil when sending a message. But this rigidity is out of step with the no-types approach of objective-C. There, the idea is that messages are freely distributed to "some" object and it'll see what it does of it. So, it tries to position itself in the Smalltalk corner rather than the Eiffel corner. While the choice between these corners is free, the consequences should be handled straight. In this case, a nil object would be an object, too. So it should answer calls with default values: NaN being the appropriate one for float's.

A >particular selector binds to an implementation in a class which >_does_ encode types - but, the Nil "class" has no such bindings.] Ok, after I couple of post, and a few emails, I think I can suitably (or not - you be the judge) enlighten folks as to what's going on here. The basic problem arises when attempting to send a message to nil and the expected return value is floating point (not type id, or int or whatever). On Intel, this results in a NaN and your program blows up. On Motorola, you get a 0.0. I had suggested that perhaps the run-time had omitted setting up the proper return value (0.0) for this case. In fact, the return value is *not* setup, but there is a very good rationale for this. In i486 architecture, floating point operations are carried out on a >>>stack<<<. You push operands, perform a series of operations, and pop off your result. Wonderful. However... this is also the crux of the problem. The run time can not arbitrarily place a 0.0 on the stack unless it is sure you're going to remove it. As others have pointed out, the message dispatcher does not know what the expected return type of the message is, and therefore can not push a 0.0 on the FP stack "just in case". So you're stuck. At least your stuck if you use the current calling conventions. There exists the possibility that a re-architected calling convention could work around this, but the same person that suggested this (someone at NeXT), also told me that other solutions also made *all* messages more expensive. So, before you mount your charger and start lobbying NeXT, you need to ask yourself how much am I willing to pay for this, and is it worth it, considering that there exist work arounds for this (as unappealing as they may seem). So... everybody got it? Great, I'm outta here... --Bob P.S.

Floating 0.0 has multiple representations under the DEC "D" floating point scheme, which is an older standard. Take a look at "man 3 math". The problem is that you run into questions of what is the return type of a message to a nil object. The calling conventions of the hardware in question may want to return the values in different registers depending on whether you're returning a float or an int. Also, you may run into what 0x0 means to your hardware, assuming that you actually get that as a return value. Basically, there isn't a graceful method for dealing with the return type of a nil object, and it would be wise to avoid sending messages to such if possible. -Chuck Charles William Swiger -- CMU...*splat*! | 1.

Furthermore, there appear to be troubles with this RTF support: only flat-file RTF is supported, and InterfaceBuilder hasn't been notified of this change. Allow me to describe a proposal to extend the functionality to include images and sound and what all, using a method that is very easy to implement (well, a lot harder if you don't control the source), and which should have been used for flat-file RTF as well (rather than fiddling with the compiler). The method has already been applied to lex and yacc sources, which can be named .lm and .ym for automatic appropriate treatment. I give the examples only for Obj-C source files (this has to be added to Makefile.postamble). .SUFFIXES: .mrtf .mrtfd .mrtf.m: @(initdir=`pwd`; \ cd $(SYM_DIR); \ cmd="rtf-ascii $$initdir/$*.mrtf > $*.m"; echo $$cmd; $$cmd ) .mrtf.o: @(initdir=`pwd`; \ cd $(SYM_DIR); \ cmd="rtf-ascii $$initdir/$*.mrtf > $*.m"; echo $$cmd; $$cmd ; \ cd $$initdir ; \ cmd="$(CC) $(ALL_CFLAGS) -I$$initdir -c $(SYM_DIR)/$*.m -o $(OFILE_DIR)/$*.o" ; \ echo $$cmd ; $$cmd ) .mrtfd.m: @(initdir=`pwd`; \ cd $(SYM_DIR); \ cmd="rtf-ascii $$initdir/$*.mrtfd/TXT.rtf > $*.m"; echo $$cmd; $$cmd) .mrtfd.o: @(initdir=`pwd`; \ cd $(SYM_DIR); \ cmd="rtf-ascii $$initdir/$*.mrtfd/TXT.rtf > $*.m"; echo $$cmd; $$cmd;\ cd $$initdir ; \ cmd="$(CC) $(ALL_CFLAGS) -I$$initdir -c $(SYM_DIR)/$*.c -o $(OFILE_DIR)/$*.o"; \ echo $$cmd ; $$cmd ) Of course :-(, rtf-ascii is not documented (at least not in NS_3.1), and it generates spurious bytes (at least for TXT.rtf it does), so it is not usable. Anyone to write an improved filter? If a functional one is available, the finishing touch would be to add a #file directive to each ``object'' .m file, to indicate to ProjectBuilder which file to open for warnings and errors. Then the system should be made aware of these new document types, so that they will get proper icons (a volunteer to design specific new ones, NeXT maybe?), and so that .?rtfd directories are treated as wrappers. The solution involves adding lines to Edit.app's __ICON/__header section, in the known format (is described in the docs), for all file extensions, and to add the corresponding icons. These changes can be applied using a script that calls segedit(1) to do the job. Then there is the problem of making Edit aware that .?rtfd things are RTFD documents. There is a function inside Edit which is essentially the following: BOOL isRTFD(const char *path){ /*var*/ int strLen; BOOL retVal; SELECT IF(a2==NULL) retVal=FALSE; INTERMEZZO(strLen=strlen(path)) IF(strLen<=5) retVal=FALSE; IF(!strcmp(path+strLen-5,".rtfd")) retVal=TRUE ; IFDEFAULT retVal=FALSE; ENDSELECT return retVal; } and which should become something like: BOOL isRTFD(const char *path){ /*var*/ int strLen; BOOL retVal; SELECT IF(a2==NULL) retVal=FALSE; INTERMEZZO(strLen=strlen(path)) IF(strLen<=5) retVal=FALSE; IF(!strcmp(path+strLen-5,".rtfd")) retVal=TRUE ; IF(strLen<=6) retVal=FALSE; IF(!strcmp(path+strLen-5,".mrtfd")) retVal=TRUE ; IFDEFAULT retVal=FALSE; ENDSELECT return retVal; } Somebody should now describe how to replace a function that is already inside an executable. Anyone? Because until this change is applied, one has to rename to .rtfd and back repeatedly, or add the necessary commands to Makefile.postamble for each specific _?.rtfd source. The final result is that you can write .?rtf and .?rtfd just as you now write .? (just add to ``Other Sources'', but I don't think the distinction with ``Classes'' is real), and I don't think that not having the ordinary .? extension for this is not an advantage, because this is all so platform-specific. Oh yes, you will have to explicitly delete old files if you migrate between degrees of richness (that's an undoubted shortcoming of Edit: it just renames a file to, e.g., UNTITLED.rtf, rather than asking for confirmation and doing the appropriate operations itself; unless it's cured in NS_3.2?), and until ProjectBuilder is adapted as well, you have to remove a file and add another by drag-dropping. Performance: Does NeXT do it *without* intermediate file? If so, what's the penalty for the extra pass? Usability: IB can parse the header file in sym/ Which release: NS_3.1 and higher, probably earlier as well. Of course, these are not very essential things. But if one adds frillies like RTF, why stop short of RTFD, for diagrams, sketches, voice comments and such? [Wishes for real improvements omitted.] Please mail proposals to me.

It is a dangerous hack that messages to nil return nil regardless of the *declared* return type of the message. That's like saying that the function double doit(int x) returns something that's either sizeof(char) or sizeof(void *) bytes long, depending on the argument or context... sorry, that's impossible in a typed, compiled language like C. {Don't say that chars are actually passed around as ints, because sizeof(void *) does not necessarily == sizeof(int)}. What defense Obj-C (or is it NeXT's flavor only?) would have been a safer language if it made messages to nil caused an immediate runtime NULL-dereference fault, much like dereferencing a function pointer that is NULL. That way, people would establish the discipline, like they have do when manipulating pointers, of testing an object for non-nil-ness if unsure before trying to send it any messages. As it is, you have to test anyway for non-id returning messages, because NeXT certainly is right that the return size, format, register usage, etc. for pointers vs. other C types varies by processor. -- Jaime Guerrero Verbing weirds language.

But it's really no use until a filter is found that doesn't produce those spurious bytes (and preferably includes a #file line). Why should I fret about .x possibly being RTF? - because it's so terribly NS-specific: it's easier to scan the extensions than inspecting the files themselves, when taking sources somewhere else; - because it's probably no solution for RTF with attachments, which is now stored in a(n .rtfd) wrapper rather than a file; - because not everything that one might like to be RTF is C source: what about yacc and lex, and other things as well, these should be able to easily mimic the functionality (my biggest argement); - because the set of allowed extensions for RTF appears to be restricted; - because make(1) relies on the extension, e.g., for a target copysourcenonrtf; - because non-source RTF still has the extension .rtf; - because by the same logic there is no use for .c: such a file can be renamed to .m and the compiler will treat it just the same, it will just be stricter in the allowed form if .c is used, which *is* useful; - maybe I forgot something. Counterarguments: - Hypertext links will break at richness migration. Well, then improve that part. Now they can't even point to their own file, one has to name that file, and they will break if the file is renamed. - It won't be possible to automatically generate a Makefile.dependencies. Well, it would be a first if 3.2 gets this to work at all, without any mention of RTF; and the present scheme is time-consuming and requires user intervention (to make depend). But hey, Makefile.dependencies doesn't have to include the RTF source: make will make that inference itself (right, I hope?). And some of my vocabulary was not (entirely) correct.

Well, you can send an ICMP protocol ECHO_REQUEST packet and see whether you get a reply, but, depending on what you're doing, you may want to save the ping overhead and simply try to open the connection (via RPC, or whatever you're doing) in the first place. Fork, and wait for a while in the main process, checking whether the child process gets a connection (remember that both child and parent process share the smae descriptors, so if the child exits cleanly, the parent can continue with a valid connection).

Perhaps, but not necessarily The Right Thing(TM). A high percentage of methods return *self*, and are essentially procedure calls rather than functions returning ids. It isn't uncommon for the targets of the message to be optional. Your suggestions forces lots of gratuitous if ( anId) [anId doit]; In particular, annoying stuff like -free { if ( anId) [anId free]; if ( another ) [another free]; } Even C++ (that bastion of safetytude) allows delete aZeroPointer; Another case: I'm working on a project where it is necessary to follow chains of attributes. If all are present, the following works: [[[[source getAttr1] getAttr2] getAttr3] doSomething]; This would become if ( temp1 = [source getAttr1] && temp2 = [temp1 getAttr2] && temp3 = [temp2 getAttr3] ) [temp3 doSomething]; In fact this particular code is in C++, so I am forced to do the latter...it's a big pain. --- NeXTMail:Peter_Kron@corona.com Corona Design, Inc.

There is one hard thing about writing a display driver for NS/FIP. Getting adequate documentation for the device. Remember that in the current world, the Window Server treats the display card as a frame buffer. It does not use accelerator features, it does not require complex drivers. To write a display driver you have to be able to do a couple of things: 1. Get the card into a specific mode 2. Get the card out of that mode and back into a standard VGA mode 3. Probe the card for various features 4. Load the palette (if the card supports a loadable palette in the desired mode. Most don't support palette based gamma correction in 16 or 24 bit mode). Sounds easy right? Well it is once you get the information you need. Here are some of the obstacles: 1. All of the people who build display cards write BIOS code that does everything listed above in one form or another). Sounds good right? Wrong. The BIOS calls are not accessible from NEXTSTEP (they all run in 16 bit mode for one thing). The bigger problem is that since this is done for you, the details of how to do this are not usually spelled out very well in the documentation of the cards (there are exceptions; for instance, the QVision documentation was very good). 2. The most interesting modes for NEXTSTEP are 16 and 24 bit color at high resolutions. I can tell you that every card for which there is now a NEXTSTEP display driver had some sort of "gotcha" in those modes. That is, they have some sort of misfeature or complexity that makes writing the drivers an adventure. A good contact at the company that makes the card is invaluable. > I don't currently have access to a NeXT (and man oh man did I get system > shock when I changed jobs and went from working on NeXTstations to > working on X terminals ...) so I can't check out these things for > myself right now: > > 1) How good is the Driver Kit in the first place? > 2) How good is the documentation for it? > 3) How good are the examples (if any) shipped with 3.2? > (Very, VERY important!) > > When NeXT first announced the Driver Kit, NeXTaholics praised it up > and down, claiming that it made it an order of magnitude easier to > develop drivers. DriverKit is quite good actually. Because of the structure it provides, writing a new display driver is significantly simplified. It is a bit of a paradigm shift from the way people are used to writing drivers, but in the end, it is a win. To anyone who has the time and interest, I recommend reading the docs, trying it out, and forming your own opinions. > I'm skeptical; if it's so good, why aren't some of > the incredibly talented programmers we have in the NEXTSTEP community > writing their own and solving the device driver crisis we're currently > in with the Intel platform? Well, it may have to do with the fact that people have jobs, families, homes, and other interests that fill their copious free time. Also remember that DriverKit does not make it any easier to understand what the CRTC register set does on a display board. To write a display driver you need to have a certain level of understanding of how a display board works. Similarly for Ethernet drivers. DriverKit provides a superclass that you can write a subclass of for a specific board. This allows you to concentrate on board related tasks as opposed to higher level details that are the same for all ethernet boards. However, you have to understand the hardware specific details of the board for which you're writing a driver. DriverKit can't help with that. > "If you want a nifty program, but it doesn't exist yet, write it." > -- Real Programmer's motto > > If it would be feasible to do so, I might be willing to buy my > wonderful god pod with some crappy generic ISA VGA adapter in addition > to my godly video adapter, so I could run NEXTSTEP while developing the > driver for the godly adapter.

Don't expect to be able to write your first display driver in a couple of days. I do believe that over time this will become easier and easier. The NeXT drivers now cover several chip families (including S3, ATI, and soon P9000[Q194]) and a variety of DACs. Plugging these compoenents together into new drivers will get easier over time.

So I pass it on with the hope that it will save someone else some gas. Here's the problem: You've developed some object which you intend to use in IB on a palette a lot. This object has the property that it has some malloc'ed string inside it. Let's call this variable "tclVarName". You do your stanard object palettization, which includes making sure that you implement, free, awake, read: and write:, so that your object will drag and drop and archive okay. You fire up IB with your new palette and start using your object. You drag a few out, inspect and manipulate them. Maybe you even cut and past a few. You go into "Test Interface Mode". You go out of "Test Interface Mode". repeat a few times. At some point in the former operations, IB crashes. It's very repeatable, but you can't get it to crash at exactly the same place. Of course you're running IB inside of gdb, but that's no help, since the stack is trashed. Since it's IB, you can't use MallocDebug, so you build a little app that loads nibs with these new objects in them, and you compile it with the library version of your palette and MallocDebug. You now can't crash this app at all, and MallocDebug (which showed me a bug once under 2.1, but hasn't since...) doesn't show any problems. Aaargh. So think. What's special about IB that this little app (compiled with the library which has the same code as the palette) doesn't have? Well,the only thing would be the Inspectors, right? So we take a look at the Inspector code. Hmm. There is no suspicious code there. You're stumped. Here's the problem: You implemented everything right, except you forgot about those seemingly innocent cut-and-paste operations you did in IB using your objects. When you did that, IB called copyFromZone:, and here's where you began to get toasted. See, the problem is that the default implementation just copies all your little instance variables into the copy's. This is fine for most things, but any private pointers (be they objects or regular ole nasty C pointers, like char*'s for strings), are bogus, because they're pointing back at the originals. So what's a poor boy to do? Let's say we have an object that has two instance variables, one tracking the string, and one giving you the size of the string buffer (so you can grow it as necessary). What do we need to implement? - copyFromZone:(NXZone *)zone { id newCopy = [super copyFromZone:zone]; [newCopy reinitializeStuffFromZone:zone]; [newCopy setTclVarName:tclVarName]; return newCopy; } - reinitializeStuffFromZone:(NXZone *)zone { tclVarName = (char *)NXZoneCalloc(zone, tclVarNameSize, sizeof(char)); return self; } I assume that you've already implemented a method called "setTclVarName" which takes a string and, after growing the buffer appropriately, copies the new string in. Exercise for the reader: why, beside cleanliness, do I make "reinitializeStuffFromZone:" be a separate method, and not perform the calloc() in the copyFromZone: method? If you can't answer that, you don't really understand what's going on... Anyway, I hope this helps somebody. I figured this out the hard way... This is a good example of something where source would have been immensely valuable - it's not that this is undocumented, just underdocumented, and very, very, very difficult to track down. - wave -- --> Michael B.

Just like you generally inherit and override -init rather than +new, in GNU Objective-C you can inherit and override -deepen rather than -copy. This separation has similar benefits to +alloc/-init, because again there are really two different objects performing parts of the operation. A sample benefit of this strategy is the ability to cleanly subclass classes that use funky memory management schemes. And now it's not just for GCC anymore :-). I've included a very simple Object category below that provides an NXZone-enhanced, deepen-based copy protocol. It basically systematizes MBJ's insight. (In retrospect I am sorry that the analog of +alloc is called -shallowCopy rather than -allocCopy, since the former may carry additional meaning. I'm guilty on this.) #! /bin/sh # This is a shell archive, meaning: # 1. Remove everything above the #! /bin/sh line. # 2. Save the resulting text in a file. # 3.

It actually only seems to be called when you matricize something in IB (i.e., alt drag out something that has a cell). So, you should still implement it the way I said, but this hasn't solved my current bug... Without boring people with the gorey details, has anyone ever written an object that was both a source and sink for a drag-and-drop operation and put it on a palette? In other words, taken the code from the NeXTWorld DragLab Example and palettized it? I've written lots of objects which are sinks for dragging that I have palettized (i.e. several different kinds of Well objects), but this is the first I've palettized that is also a source. The problem is that at some point after I do the first "test interface mode", IB crashes in that object's mouseDown:, as I call declareTypes:num:owner. I'm running out of ideas here... sigh. -- --> Michael B.

For instance, I set double action and I then receive double-clicks no problem. But, overriding mouseDragged: has no effect. Somebody up the chain is not passing down the mouse dragged events (probably because this is a matrix and it does it's own stuff with mouse drags, i guess...). So, okay. I make my own event loop on a mouseDown. I now can grab the mouse dragged events no problem. But, I no longer get my double click actions (of course). Seems strange, if it isn't gonna give me mouseDragged:, why does it give me mouseDown:? Anyway, do I have to figure out how to get the double click from within my loop (this scares me), or is there some way I can make my object respond to the mouseDragged: message? jim. wissner@beech.csis.gvsu.edu

But many methods returning self also return nil to indicate an error. So while the above style may be a pain in the ass, crashing apps are a bigger pain in the ass. In December, 1990, Communications of the ACM published an extensive study of the sources of bugs in applications, utilities, etc. The study concluded that writing the most bullet-proof code required the strict following of 8 guidelines among which was checking the return values of all functions that can return an indication of an error, even when an error is unlikely or the response to an error would be awkward. Yes, following these guidelines is more of a pain in the ass than assuming that the return values can never, under any circumstances, indicate an error condition. But one should always expect the unexpected because users are sure to create the unexpected. Many C programmers like to see how curt and compact code can be written. While this may be cute and while C (and Objective-C) may support it, this style frequently leads to problems down the road when the unforeseen occurs. How many would have predicted that sending a message with a float return to a nil target would have returned a non-zero value as it does on Intel hardware? Those of us who have written pain in the ass code are now finding it no pain in the ass whatsoever to recompile our code for Intel hardware. -- Art Isbell Cubic Solutions NeXT Registered Developer NEXTSTEP software development and consulting NeXTmail: art@cubicsol.com Voice: +1 408 335 1154 USmail: 95018-9442 Fax: +1 408 335 2515

Message-ID: <CHMuB7.s6@northstar.com> Keywords: Has anyone gotten this to work? Sender: usenet@northstar.com Organization: NorthStar Technologies, inc. Distribution: usa Date: Mon, 6 Dec 1993 21:28:17 GMT We are using the Gupta database on NS/FIP along with the Gupta adaptor supplied as part of the Parabase package. However, we are running into some fundamental problems with it which leads us to believe that this shipped product isn't, umm.. completely functional. Or even usable as is. First of all, it cannot deal with DBBinder structures and perform selects. After setting up the DBBinder (ala DBBinder example under the /NextDeveloper/Examples/DatabaseKit/Binder directory) and the correct record prototype, it chokes with the error message under gdb: Unknown error code 6001 in NXReportError This happens on the [binder select] operation. (Note that [binder fetch works ok.) Next, with the DBModeler app and creating a new DBModule, it fails to recognize ints, floats and other data types, and defaults everything to type double. This was a matter of some concern, since our database contains > 1600 fields and to modify them all manually using point and click would take a while. So we opened up the ascii version of the dbmodel (the .dbmodela file) and just for kicks compared with the Sybase version of the same dbmodel. Voila! It seems the Sybase version has much more type information within it. Here are the two versions for a single table within the Pubs demo database (the Gupta version was recreated): Sybase version ========================================================================= (discounts, discounts, "", N, ( (discount, discount, "", N, d, float, "", "", N, N, N, N), (discounttype, discounttype, "", N, "*", varchar, "", "", N, N, N, N), (highqty, highqty, "", N, i, smallint, "", "", N, N, N, N), (lowqty, lowqty, "", N, i, smallint, "", "", N, N, N, N), (stor_id, stor_id, "", N, "*", char, "", "", N, N, N, N))), Gupta version ========================================================================= (DISCOUNTS, DISCOUNTS, "", N, ( (DISCOUNT, DISCOUNT, "", N, d, "", "", "", N, N, N, N), (DISCOUNTTYPE, DISCOUNTTYPE, "", N, "*", "", "", "", N, N, N, N), (HIGHQTY, HIGHQTY, "", N, d, "", "", "", N, N, N, N), (LOWQTY, LOWQTY, "", N, d, "", "", "", N, N, N, N), (STOR_ID, STOR_ID, "", N, "*", "", "", "", N, N, N, N))), As you can see the second (Gupta) version has next to no type checking (other than setting all numeric types as double) and none of the additional type information which is included in the Sybase version of the dbmodel. Needless to say, this doesn't work for us. Does anyone have any ideas on how to fix this? Or even better (hope, hope) does anyone know how to write an adaptor or maybe have one written already for Gupta? All comments, suggestions and ideas welcome. Email rashid@northstar.com Thanks, Ruze

But you can check the register which contains the return value. For Moto systems, it's $d0. I'm not sure what it is on Intel, but it's prbably some really sick name like $ax. Do an "info reg" to see all the registers gdb knows about. You can always dissasemble the last few lines of a function on any platform to see where it sticks it's return value.

For all of NeXT's additional operator, there is an equivalent way of getting the same information through X. It may not be as easy or as pretty, but that should end up being hidden by the AppKit as long as you don't use those specific operators in your apps. There may be addition server round trips involved in this, but hey, you don't expect OpenStep/X to perform as well as a full blown NEXTSTEP, did you? Besides, for every piece of information that can be had through X, a little bit of work could allow accessing that same information through Display PostScript. Most likely, with little work, OpenStep can be completely compatible with the current "NeXT only" operators. As a worst case scenario, let's consider what happens to hit detection without the mouse operators. You'd have to make an AppKit call to get the mouse coordinate, then you can call your hit-detection wrap with two additional parameters. An extra round trip, to be sure, but not much programming pain. On top of all this, *nobody* is sure what's going to really end up happening. -- Scott Byer NeXTMail: byer@mv.us.adobe.com Adobe Systems Incorporated These are *my* opinions, and 1585 Charleston Road, P.O.

Would this be a problem, then: @implementation Bla : Object { float something; } ... -(float)value { return something; } ... id obj=[self getThatBlaInstance]; unsigned ret=[obj value]; ... obj will be an instance of Bla - but, since I declared it as an id, the _compiler_ doesn't know this. In the earlier barf() case, I think that the compiler _could_ conceivably handle that float on the stack easily enough. But, in this case, it cannot. So, would this case be a potential problem on the order of treating the return value of a message to nil as a float?

Hmm, I'm not convinced of this [for this particular case]. Consider ... the base of the problem is that we're returning floats in one place and ints in another. Why not return both in a single register? For all calls which _don't_ have anything to do with the float, this is no hairy deal, because they just work as normal. For those few calls returning a float, there is now the added overhead of moving the float from the floating stack to a register, and back at the end if we want to use it in an expression. But such overhead should be trivial compared to the message dispatch itself. [This doesn't, of course, consider potential loss of precision converting from the internal FPU form to a 32-bit value - but that's something else dangerous to rely on. It also doesn't address a host of other problems, such as handling of doubles and How Things Work On Other Platforms. In other words, CHECK FOR NIL!] [Another reason to check for nil. The code: if( anObj) { [anObject aMessage]; } runs faster in the nil case than: [anObject aMessage]; because there's a non-zero overhead for nil messaging. On the other hand, it also adds a non-zero overhead for the non-nil case. Depending on frequency of call (ie, if called once or three times in a run, who cares?) and likelihood of the value being nil (often high with NeXT's emphasis on delaying creation and loading until need for performance reasons), this may be worthwhile.] Later, -- scott hess <scott@nic.gac.edu> <I can handle NeXTMail, but don't like it> 12901 Upton Avenue South, #326 Burnsville, MN 55337 (612) 895-1208 Anytime! <C++: ...

However, please note that some of the people at NeXT do read these groups; hearing things like "I wanna do this...", or "wouldn't it be nice if OpenStep meant..." may very well give them some new ideas (different perspective, perhaps). I would imagine that many of the important points people have discussed on the net are the points that NeXT as a company is working to resolve in order to codify the OpenStep specification and work towards NS 3.3 (or NS 4.0).

On the m68k, *both* int and float return values are stored in d0. Other machines may store floating point return values on the stack, or in a floating pointer register, etc. > [There is a decent solution, of course. With ANSI prototyping, > the compiler knows enough to drop the value from the stack if it's > not used. Anyhow ...] Yes. That's the main reason for argument prototyping; it can catch some of the more subtle bugs about doing the wrong things with argument lists. Unfortunately, you lose this typechecking when you have variable argument lists and/or you are dealing with a function with potentially variable return types, as is the case with a message to nil. Note that the typical convention has the callee restore the stack pointer correctly so that the calling function has everything pointing correctly and you won't actually corrupt the stack if you return an extra value there when you shouldn't have. The calling convention on many machines also has an additional pointer called the frame pointer that helps the function to distinguish its automatic variables. Note that gcc has an option '-fomit-frame-pointer' which: -fomit-frame-pointer Don't keep the frame pointer in a register for func- tions that don't need one. This avoids the instruc- tions to save, set up and restore frame pointers; it also makes an extra register available in many func- tions. It also makes debugging impossible on most machines. > [And it does leave one more question - where's that NaN come from? > Is it just a stack-underflow type of thing?

You should be able to leave a floating return value on the stack when the callee restores the stack pointer (and the registers the callee uses, if you're doing callee-save).

I agree that having all messages return an alternate 'phantom' return value would make everything slower; however, you can handle the specific case of sending a nil message without penalizing all message calls. Hmm, that's assuming that we're using caller-save. If we're using callee-save, then at the least, the caller must expect the standard return registers to get overwritten. This makes everyone's code potentially less efficient because you'd have to spill (save temporarily) the return register(s) before each function call if your function is complex enough to want to use all available registers. > Hmm, I'm not convinced of this [for this particular case]. Consider > ... the base of the problem is that we're returning floats in one > place and ints in another. Why not return both in a single register? Your hardware may simply not allow you to do that. Note that the reason people haven't had problems with this before on black hardware is that the m68k does return both int and float in the same place, so storing a single value there does work correctly. This is not the case on an Intel machine. > For all calls which _don't_ have anything to do with the float, > this is no hairy deal, because they just work as normal.

But such overhead > should be trivial compared to the message dispatch itself. The problem is that you have the potential of making *every* function call (not message, mind you, but function call) slower. Returning floats on the stack means that they'll do the correct thing in the specific case of a nil-object message, but that means that hardware that can return floats in registers are slower than necessary. Returning both a float and an int for just a nil message will work if both can go into registers, but you've made every function call have to deal with one more register being overwritten after each function call. > [This doesn't, of course, consider potential loss of precision > converting from the internal FPU form to a 32-bit value - but that's > something else dangerous to rely on.

In other words, CHECK FOR NIL!] Doubles and 64 bit integers are returned in integer registers d0 and d1 on the m68k. This means that callers must expect both d0 & d1 to be clobbered even for objects/functions returning void or else they would be incorrect in the case of a message to an object (call to a function) that tried to return something anyway. -Chuck Charles William Swiger -- CMU...*splat*! | 1.

Well, NS 3.2 is here and unfortunately the fix didn t make it into this release either. So I tried to fix it. It s a good exercise if you want to understand how make works. But... I ran into trouble. I hope some of you "make - gurus" in the net can help me. First the bug: Take /NextDeveloper/Examples/AppKit/Graph and make the project, (with the target debug for example). It should succeed. Now touch expr.ym and make the project again. You ll get the following error: yacc -d /disk/ROBOT0S4-2H/home/hoffmann/Junk/Graph/expr.ym mv y.tab.c sym/expr.m mv: sym/expr.m: rename: No such file or directory *** Exit 1 Stop. *** Exit 1 Stop. The problem is in basicrules.make, in the suffix rule ym.m .ym.h: @(initdir=`pwd`; \ cd $(SYM_DIR); \ cmd="$(YACC) $(YFLAGS) $$initdir/$*.ym" ; echo $$cmd; $$cmd ; \ cmd="$(MV) $(MVFLAGS) y.tab.c $*.m" ; echo $$cmd; $$cmd ; \ cmd="$(CP) $(MVFLAGS) y.tab.h $*.h" ; echo $$cmd; $$cmd ) If you put an echo for $* in it, you ll see the first time $*.m expands to expr.m, which is ok. The second time it expands to sym/expr.m which causes the error because we already are in the subdir sym and there is no file sym/sym/expr. I don t know why $* acts differently. $* is the prerequisite of the current target and if you use it alone it always expands correctly to expr. If $*.m is used the following happens: If the current target is expr.m $*.m expands the first time to expr.m and the second time to sym/expr.m. -- uwe....................................hoffmann@fzi.de (nextmail ok)

It's a rather big jump from optional references which may be nil to ignoring error returns from critical functions. Of course, errors should be checked. Assertions should be used.

First of all, Virtuoso only has 2 2 ``modes'' for text. There's the standard ``container'' mode (tab ruler, etc) and ``text-on-a-path'' mode. Tab rulers always appear with text containers. If you have the ``Changing Elements Changes Defaults'' preference on (the default) then when you change a containters' tab settings, subsequent containers have that same setting, so if you aren't expecting that then it could cause problems.

Nothing machine-independent. But you can check the register which contains the return value. For Moto systems, it's $d0. I'm not sure what it is on Intel, but it's prbably some really sick name like $ax. Do an "info reg" to see all the registers gdb knows about. You can always dissasemble the last few lines of a function on any platform to see where it sticks it's return value. Eventually, you'll end up with a repetoire of hidey-holes.

I tried ping remoteMachineName 64 3 on a machine which exists in our local network, but was down at the time, and after 12 seconds it exited successfully. It seems that ping always gives the success exit for known local machines, even if said machines are down. (On the other hand, if the machine is unknown, ping gives a failure exit, as desired.) Long ago I fiddled with a program, based on ping, to find out what machines were up on the local network, but there was some annoying bug, and finally I ran out of time and came up with the following gross kluge: ruptime | egrep -s '$remoteMachineName *up' This returns true if remoteMachineName on the local network is up and running the rwho daemon. It has the advantage of not loading the net. It has a plethora of disadvantages: 1) Your machines must be running the rwho daemon, and have the ruptime command. 2) There is a latency of a few minutes after a machine goes down before ruptime catches on; when a machine comes up, the latency is shorter. 3) It will break if ruptime output format changes 4) You call this programming? However, it's so cheap and dirty, I can't resist it. signature: Permission denied

I think you'll see what I mean. As you probably know, I'm dealing mostly with Packaging Graphics. Quite often I simply need to add a line or two of type in some remote corner of a package. The two ways of doing this in virtouso involve either a big text box or the need to first create a path (or two) and link the type to it. Both of these methods are very cumbersome in such an instance. Seeing as how such instances occur 30 - 50 times a day this is my #1 feature request. I forget if I mentioned it earlier, but another much needed feature would be the ability to save as an eps but still be able to edit the file in Virtuoso. Like Illustrators save with eps header option. This would be especially valuable in NS since the exact same file could be edited by me and viewed through drag & drop by any other NS app. The only trick I see here would be to get Virtuoso to recognize .eps files that were really .vrt files. (it's beginning to sound alot like tailor :-) Last but not least! Why doesn't Virtuoso use the edit menus spell checking capabilities?!?! One of my primary resons for getting NS in-house was because of the highly sensible common spell checker. The place I need it most is in your app. I hope this has been of interest to the group. I decided to post it here to give some more visibility to this outstanding app. Thanks, Michael Rutchik ludwig@well.sf.ca.us

The standard Cirrus mode is 1024x762x2 *interlaced*. I know that the chipset and my monitor can both cope with a non- interlaced raster at this resolution, so I'd like to try changing the card mode (after the driver is loaded at boot time) with a little program of my own. I'm in the process of tracking down information on the registers that I'll have to diddle to do this. I know that VGA registers are mapped into the PCs I/O address space (as opposed to the memory address space), having done lots of VGA diddling in the DOS domain. DOS compilers provide special instructions for reading & writing I/O address locations ( inportb() and outportb() in Turbo/Borland C++), but I don't know how these operations can be done in NeXTSTEP. Does the modified GCC in NS 3.1/FIP contain instructions for I/O-port manipulations? -------------------------------------------- Gary Finley, Univ of Alberta Psychology Dept. gfin@psych.ualberta.ca (NeXTmail welcome!)

If it's really true that functions that return floating-point values leave the return code on the stack, all kinds of havoc could result. Then again, maybe this is why even in K&R C you had to declare the return types of functions. Consider the following code: int main(argc, argv) int argc; char **argv; { int max; int i; max = atoi(argv[1]); for (i=0; i<max; i++) float_returning_fn(); } float float_returning_fn() { return 2.23606797749; } Even K&R C compilers choke on this; float_returning_fn() is implicitly declared to return int by the reference to it in main(), so the float return type given in the real declaration is an error. I guess this is good. But if you were to compile the functions separately and link them, it would compile fine. But when you run it, give it a huge value on the command line; and whatever stack the floating-point return codes get put on will get huge and chew up lots of VM. I think it's an invalid program, so I guess that's reasonable. Declaring the wrong return types is a no-no in general. You certainly couldn't reasonably expect a program like this to work and not chew up large amounts of VM if you were returning large structs instead of floats. I wonder how much simpler the definition of Standard C would be if we didn't have architectures like the x86 chips that had to be supported ... ...jkd

I believe I got it from purdue about a year ago. It seems to work ok all the times I have played with it. More recently is the MOKit that has a palette called DocumentWell (or something like that).

I'm sorry, but you are not correct. If the compiler does not have bugs and you are using any sane calling convention, then it will not permit you to corrupt and/or inflate the stack in the manner that you seem to expect. Consult the new dragon book: "Compilers -- Principles, Techniques, and Tools" by Aho, Sethi, & Ullman, around p. 407 for examples of calling conventions that will handle your example without a problem. -Chuck Charles William Swiger -- CMU...*splat*! | 1.

Is anyone out there specifically proud of his/her/their error handling system? Do you have a failure recovery system? Like "OK, I don't get these 4K for this string, so I exit()." vs. "I'll make do with 2k, too". Are there any real concepts on failing system calls? I see a lot of unchecked malloc calls, as an example, but feel rather stupid when checking the notorious malloc(5). Do you feel that NeXT / Obj-C shows any consciousness for that problem? Any idea on how NXCopyStringBuffer assures availability of memory? Or doesn't it? I'm not involved in any BIG project and anything I do is of my own crutching and consists mainly of NXRunAlertPanel(). Many calls are bracketed by if()..., but that looks ridiculous sometimes. Is there a known way to catch a number of failures elegantly? like try these, skip rest on failure open file, but close it on error get memory, but free it on error write memory to disk, remove file on error close file, free mem return 1 continue here when above failed open another file ... get less memory... return 2 Well.. Do you get the idea? Try to rewrite it with if's and you'll see what I mean. I can talk a little on the error mechanisms of the eiffel language. Pieces of source code can "require" and "assure" conditions, loops can have "invariants" and "variants" and all these things can be checked by the running programs. If such an assertion is violated, an exception is raised and the caller has to take care of the exception, else it bounces up and up until it surfaces to the user. The problem is that this mechanism is intended for the debug phase to assure correct programs, not to take care of, say, system faults. Well, let this be a starter. Comments anyone?

There was an interesting article in "The C Users Journal" Vol. 11, No. 10, October 1993, Pg 33-46. It describes a set of macros (covered by GNU Library General Public License) that give you a nice way of handling exceptions. Some things that are provided are unwind-protect blocks, exception domains, and error handlers. I ftp'd the source but was unable to get it to work on the NeXT. However, please note that at the time, I gave it about 5 minutes of my attention (I think I missed some relavant files). For those interested, check out: ftp.bion.kth.se:./cvap/2.0/README - Steve P.S. If anybody had (or has) success with these, please let me know.

The bug shows up in the way `%g' formats floating point numbers when it chooses to use %f (as opposed to %e) representation. The ANSI standard (X3.159-1989) says (Section 4.9.6.1, page 134, line 33): g,G The double argument is converted in style f or e (or in style E in the case of a G conversion specifier), with the precision specifying the number of significant digits. If the precision is zero, it is taken as 1. The style used depends on the value converted; style e (or E) will be use only if the exponent resulting from the conversion is less than -4 or greater than or equal to the precision. Trailing zeros are removed from the fractional portion of the result; a decimal-point character appears only if it is followed by a digit. *** NOTE THE WORDS `significant digits'. *** Here's a little test program, and some results from the machines I have access to at our lab: ============================================================================ #include <stdio.h> int main (int argc, char **argv) { printf ("Expect 0.00123: %.3g\n", 0.001234567); printf ("Expect 123: %.3g\n", 123.4567); printf ("Expect 123.5: %.4g\n", 123.4567); printf ("Expect 1e+03: %.3g\n", 999.6); return 0; } ============================================================================ On a SUN 4/380 (SUNOS 4.1.1): Expect 0.00123: 0.00123 Expect 123: 123 Expect 123.5: 123.5 Expect 1e+03: 1e+03 So it would appear that at least *one* vendor can get it right!

Newsgroups: comp.sys.next.programmer From: jfr@aspen.pdh.com (Jon F. Rosen) Subject: Weird happenings in grouped (boxed) fields Message-ID: <CHpC26.FsE@pdh.com> Sender: news@pdh.com (USENET News Account) Organization: PDH, Inc. Date: Wed, 8 Dec 1993 05:46:54 GMT There are some weird problems with sizing and resizing as it effects grouped fields (i.e., fields in boxes) and their relationship to one another. Put three buttons of equal size in a box and make them adjacent to each other and make the box fit tightly around the buttons (no title, overlap or border), and then make the buttons appropriately "springy" (i.e., the right and left buttons are fixed to their respective edges but are both springy to the opposite side AND springy in the middle and can thus resize, and the middle button is springy on both sides and springy in the middle). Make the box fixed to the right and left sides of the window and springy in the middle so it too can resize. Now size and resize the window, sometimes fairly widely. The buttons will tend to "creep", usually to the left, but occasionally to the right, ultimately causing two or more buttons to overlap and the widths of the buttons to become unequal. This is BAD behavior. Am I doing something wrong? I am only using IB to set up the situation since I hoped there was no need for programming. Motif's sizing and positioning capabilities are much more powerful and straightforward (one case where I think NeXT could learn something from Motif, one of the few). And I have never had this unpredictable results situation. I assume this has something to do with the numeric computations that go on inside the size/resize methods and the fact that the precision of widths, heights and x-y positions are in integers. This is bad. Postscript is capable of handling floating point positioning and NeXT should be using numbers that can be MUCH more accurate and let the Postscript window system align things to integer pixels. I hope I can remedy this behavior but I have a feeling the only solution is to programmatically reset the x-y and h-w settings to appropriately adjusted ones whenever a window is resized. This is going to be YUCHY. And please don't suggest that I use a matrix. This is a set of pull-down menus and I could not get a matrix of them in IB now matter what I tried. I imagine I could programmatically set one up but I am not going to tackle that now. Jon Rosen

Another important point, here, is that often the "nil-ness" of one object indicates something about other objects or data. For instance, perhaps three or four objects "go together", and if you know that one of them is nil - you know that the rest are, too. > And as Scott Hess has pointed out, the following is even "safer" in >that it may prevent crashing should the freed object be erroneously >messaged later: > > if (anObject != nil) > { > anObject = [anObject free]; > } To elaborate on a couple essential points I use in my Day To Day Coding which seem Right Up This Alley ... I feel that the programmer should make certain to the best of their ability that the instance variables of an object are _always_, and I mean _ALWAYS_ valid. The _only_ time that you can safely get away with leaving them invalid is if you can _guarantee_ that they will not be accessed except by routines that know about their invalidity. This usually means that only a well-defined subset will access them. _Never_ assume that something will work. A direct result of this idea is that I will always code -free methods like: - free { anObject=[anObject free]; return [super free]; } Thus, even after the object is freed, if someone attempts to go in and access the anObject instance variable (which they may or may not still be _able_ to successfully accomplish), they'll get a nil. Which is almost always better than getting Yet Another pointer to invalid memory. Furthermore, I always try to make certain that I invalidate even non-object elements, and in an order which guarantees as well as possible that if I crap out right in the middle of -free, everything is still valid. For instance, in some code that implements the same functionality as List (on a different platform), it looks like: - free { numElements=0; maxElements=0; NXZoneFree( [self zone], dataPtr); dataPtr=NULL; return [super free]; } [Note that the "terminology" used for the instance variables matches that used for NeXT's List.] In this case, setting numElements and maxElements (both unsigned) to 0 _first_ is alright, because then if anyone accesses them, they will know that nothing in dataPtr (an id *) is valid. Then dataPtr is NULLed so that they can't even make the attempt. Admittedly, this can't be done in all cases. Sometimes you have to bare your *** to the wind and hope things fall out right. But, being defensive can't _hurt_. Another point that people seem to miss terribly is how -init* methods should be coded. I see _way_ too much code that does things like: - init { [super init]; myInteger=10; myId=[[AnObject allocFromZone:[self zone]] init]; return self; } Note that right there at the end, you call "return self". Know why? Because, -init can return either the instance -init was sent to, nil, or an instance different from the one -init was sent to (the first two cases are standard NeXTSTEP things. The third isn't, but is useful in certain instances where functionality similar to -finishUnarchiving is required). If nil is returned from [super init], then "self" may or may not exist anymore! If it _doesn't_, then the assignments may wreak havoc - but, even if it does, they aren't going to work quite as expected. IMHO, the correct way to code -init* is as: - init { self=[super init]; if( self) { myInteger=10; myId=[[AnObject allocFromZone:[self zone]] init]; } return self; } [One assumption you might note that I still make (for now) is that (id)0 will evaluate to false in an if() statement. It's probably a safe assumption, but an explicit self!=nil is more precise.] You might even want to add: if( !myId) { self=[self free]; } This way, if [super init] returns nil, it's propagated. If [super init] returns a different object, it works (more or less - it would only work if the returned object was kindOf the class the -init is in, of course). If it returns the same object, it works. Another good point that Art touched on is that you shouldn't assume that the reader knows things if you don't need to. This means that in cases where it's important that "myInteger" be initialized to 0, you should initialize it to 0. Yes, +alloc* will give you zero'ed out space for the instance, which means that myInteger should already be 0 ... but, as this thread has proven, assumptions can really bite you in the end. It's not like you are saving a heckuva lot of time by skipping the initialization. A decent compiler should code myInteger=0 shorter and faster than something more complex, like myInteger=666, because most CPUs have various odd instructions that can either do it direct or quickly load a zero somewhere and store it. If you do multiple myInteger=0 type calls, it can optimize even more (it has a zero to work with). You only initialize once - but you track down bugs forever.

What this means is that more than one machine on the same network can have an object that has registered with the same name. The problem you will have is that when you do a -connectToName:"name" onHost:"*", the object you get is the first one that responds to the NetNameServer request. Also, if no machines respond in time (default timeout is 15 seconds), the method returns nil. This doesn't necessarily mean that there aren't any other machines out there with an object with that registered name, it just means none of them responded in time. In your case, where you want more than one of the objects with the registered name you will need to query each host individually (I know, what a pain). This definitely would pose a problem if you don't know what machines are out there that might be running the desired process. > -- > Marc Guenther > ------------------------------------------------------------------------- > Centrum fuer Informations | Wagmuellerstr. 23 | Phone: +49 89 211 0670 > und Sprachverarbeitung | 80538 M"unchen | Fax: +49 89 211 0674 > University of Munich | Germany | yoda@cis.uni-muenchen.de > ------------------------------------------------------------------------- Eric Brown NEXTSTEP Consultant CG Computer Services ericb@sbcoc.com

However, I _haven't_ seen anything on error handling that is unique to the AppKit or Objective-C. I believe that C++ is beginning to address, or has addressed, error handling through exceptions (I quit C++ in disgust long before any of its glaring problems were corrected, and thus I am not up to date). The exceptions I do know about are ADA exceptions. A quick example: begin < Some sequence of statments > exception when Constraint_Error => < Some sequence of statements > ... end; If an exception is raised in the block between the begin and the end, the program continues execution at the exception handler for that exception. Note that exceptions can be caused a program error or by use of the raise <SOME EXCEPTION>; statement. If the exception block cannot handle the exception (either there is no exception block, or there is no handler for the specific exception and there is no generic exception handler), the exception is passed to the calling block. In this way the exception is propagated until it is handled or it causes the program to halt. In a OOP language (No flames from the ADA zealots, please), I am not suthe exception should be passed to the super class, the calling block, or both. Interesting idea, tho. I would think that a really robust OOP language would have a nice way of dealing with error handling AKA exceptions. How does smalltalk, and the other _TRUE_ (Again, please no flames) OOP languages deal with this?? Clay

NeXT, what about this ??? I think this is a major disadvantage of PDO !!! I want to be sure, that Im the only server in the local network, or else my program would be useless... Hmmm... This should be very easy to do for someone with sourcecode access to PDO. Just add a new method, eg. allObjectsWithName: which does the same as connectToName:onHost:"*" just it returns a List off ALL responds within a specific time. What would help me a lot is a way to specify connectTo...onHost:<all hosts in the LAN except my own> This way a server for itself could query the net sometimes, and tell all other servers it finds to go away.

Depending on the setting of the radio switch matrix, one or more of the boxes (except the switch matrix which is always active) will be disabled (by disabling any controls and greying any text). Each time the a switch matrix button is pressed, the 'button pressed' method for that button enables and disables the proper boxes. The problem occurs intermittently whenever you change the enabled/disabled states of one or more boxes and try to put the curson into one of the text fields, scroll view or browser in an active box. Since this is occuring in AppKit code, I wonder if there is anything common that someone else has seen that sounds similar to this problem, and what did you do to solve it (or end-run around it). I am not even sure where to start debugging something like this. The other major problem has to do with -disableDisplay and -reenableDisplay and -display. When I used -disableDisplay to turn off updates to the display until my modifications were completed, I would get a SegFault when I did a reenableDisplay. Again, the errors were deep in the reenableDisplay method under some subView, not apparently in my code. I don't have a trace for this problem but I will try to post one. Thanks for any help you can give me. Jon Rosen

This is a good point, and Scott goes on to discuss order of freeing things so that the object is always (as much as possible) in a consistent state.

When I first saw that, I thought Scott was on drugs, but amusingly enough, the first two NeXT code examples I pulled out of Librarian used this convention - and they were recent DBkit examples. A lot of the older AppKit examples don't do this. It makes sense if you read his original explanation carefully. The case of [super init] returning 'nil', which should be propogated, is reason enough for me.

That's a joke! Message-ID: <2ec8a7$74a@steffi.demon.co.uk> Postings asking how to build perl under NeXTSTEP come up very often in this group so I decided to put together this tutorial in order to alliviate this problem. NOTE: For Mr Christiansen please archive this and add a pointer in the FAQ. This is certified for NS3.1. Building PERL 4PL36 for NeXTSTEP can be a tricky business owing the some assumptions made by Configure and NeXT's /usr/include/ tree. Common problems are Configure finding dirent.h before dir.h and thus defining both i_dirent and i_sys_dir in config.sh The most common mistake is entering /usr/include when it asks for this path. If you do this Configure then attempts to see if you have certain header files in order to determine what language features to support. So for instance if you entered /usr/include, during Configure it attempts to locate grp.h using test -f /usr/include/grp.h This file doesn't exist there under the NeXTSTEP's include tree thus it is necessary to enter /usr/include/bsd when it asks for the include path. Here is a transcript from a Configure session. root:/Users/robert/archives/perl-4.036>Configure 9:35 Beginning of configuration questions for perl kit. First let's make sure your kit is complete. Checking... Looks good... Checking your sh to see if it knows about # comments... Your sh handles # comments correctly. Okay, let's see if #! works on this system... It does. Checking out how to guarantee sh startup... Let's see if '#!/bin/sh' works... Yup, it does. Checking echo to see how to suppress newlines... ...using \c Type carriage return to continue. Your cursor should be here--> This installation shell script will examine your system and ask you questions to determine how the perl package should be installed. If you get stuck on a question, you may use a ! shell escape to start a subshell or execute a command. Many of the questions will have default answers in square brackets--typing carriage return will give you the default. On some of the questions which ask for file or directory names you are allowed to use the ~name construct to specify the login directory belonging to "name", even if you don't have a shell which knows about that. Questions where this is allowed will be marked "(~name ok)". [Type carriage return to continue] Much effort has been expended to ensure that this shell script will run on any Unix system. If despite that it blows up on you, your best bet is to edit Configure and run it again. Also, let me (lwall@netlabs.com) know how I blew it. If you can't run Configure for some reason, you'll have to generate a config.sh file by hand. This installation script affects things in two ways: 1) it may do direct variable substitutions on some of the files included in this kit, and 2) it builds a config.h file for inclusion in C programs. You may edit any of these files as the need arises after running this script. If you make a mistake on a question, there is no easy way to back up to it currently. The easiest thing to do is to edit config.sh and rerun all the SH files. Configure will offer to let you do this before it runs the SH files. [Type carriage return to continue] Locating common programs... cat is in /bin/cat. cp is in /bin/cp. echo is in /bin/echo. expr is in /bin/expr. grep is in /bin/grep. mkdir is in /bin/mkdir. mv is in /bin/mv. rm is in /bin/rm. sed is in /bin/sed. sort is in /usr/bin/sort. tr is in /usr/bin/tr. uniq is in /usr/bin/uniq. Don't worry if any of the following aren't found... I don't see Mcc out there, offhand. bison is in /usr/local/bin/bison. cpp is in /lib/cpp. csh is in /bin/csh. egrep is in /usr/bin/egrep. I don't see line out there, either. nroff is in /usr/bin/nroff. perl is in /usr/local/bin/perl. test is in /bin/test. I don't see uname out there, either. yacc is in /usr/bin/yacc. Using the test built into your sh. Checking compatibility between /bin/echo and builtin echo (if any)... They are not compatible! You are probably running ksh on a non-USG system. I'll have to use /bin/echo instead of the builtin, since Bourne shell doesn't have echo built in and we may have to run some Bourne shell scripts. That means I'll have to use -n to suppress newlines now. Life is ridiculous. Your cursor should be here--> First time through, eh?

You aren't running Eunice. It's not Xenix... Nor is it Venix... Some systems have different model sizes. On most systems they are called small, medium, large, and huge. On the PDP11 they are called unsplit and split. If your system doesn't support different memory models, say "none". If you wish to force everything to one memory model, say "none" here and put the appropriate flags later when it asks you for other cc and ld flags. Venix systems may wish to put "none" and let the compiler figure things out. (In the following question multiple model names should be space separated.) Which models are supported? [none] Use which C compiler? [cc] Some C compilers have problems with their optimizers, by default, perl compiles with the -O flag to use the optimizer. Alternately, you might want to use the symbolic debugger, which uses the -g flag (on traditional Unix systems). Either flag can be specified here. To use neither flag, specify the word "none". What optimizer/debugger flag should be used? [-O] Your C compiler may want other flags. For this question you should include -I/whatever and -DWHATEVER flags and any other flags used by the C compiler, but you should NOT include libraries or ld flags like -lwhatever. For instance, this would be a good place to specify -DDEBUGGING. To use no flags, specify the word "none". Any additional cc flags? [ -I/usr/include] (C preprocessor flags: -I/usr/include) Any additional ld flags (NOT including libraries)? [none] Checking for optional libraries... Found -ldbm. Found -lsys_s. Some versions of Unix support shared libraries, which make executables smaller but make load time slightly longer. On some systems, mostly newer Unix System V's, the shared library is included by putting the option "-lc_s" as the last thing on the cc command line when linking. Other systems use shared libraries by default. There may be other libraries needed to compile perl on your machine as well. If your system needs the "-lc_s" option, include it here. Include any other special libraries here as well. Say "none" for none. Any additional libraries? [-ldbm -lsys_s] Checking alignment constraints... Doubles must be aligned on a how-many-byte boundary? [2] The following questions distinguish the directory in which executables reside from the directory in which they are installed (and from which they are presumably copied to the former directory by occult means). This distinction is often necessary under afs. On most other systems, however, the two directories are the same. In which directory will public executables reside (~name ok)? [/usr/local/bin] In which directory will public executables be installed (~name ok)? [/usr/local/bin] In the following, larger digits indicate more significance. A big-endian machine like a Pyramid or a Motorola 680?0 chip will come out to 4321. A little-endian machine like a Vax or an Intel 80?86 chip would be 1234. Other machines may have weird orders like 3412. A Cray will report 87654321. If the test program works the default is probably right. I'm now running the test program... (The test program ran ok.) What is the order of bytes in a long? [4321] Checking to see if your C compiler can cast weird floats to unsigned Yup, it does. Now, how can we feed standard input to your C preprocessor... Maybe "cc -E" will work... Nope...maybe "cc -E -" will work... Yup, it does. Your (shared) C library seems to be in /lib/libsys_s.a. If the guess above is wrong (which it might be if you're using a strange compiler, or your machine supports multiple models), you can override it here. Your C library is where?

Note that the documentation contradicts itself here (surprise...): >>>>> (from 3.2 -[Object init] documentation) Subclass versions of this method should return the new object (self) after it has been successfully initialized. If it can't be initialized, they should free the object and return nil. In some cases, an init method might free the new object and return a substitute. Programs should therefore always use the object returned by init, and not necessarily the one returned by alloc or allocFromZone:, in subsequent code. [...] - init { [super init]; /* class-specific initialization goes here */ return self; } <<<<< Sigh! Yet another candidate for KBNS... Why would a subclass be less vulnerable to the possibility that a superclass would return a different object? Well, it's rare for this to happen, so it's unlikely you'll get stung by this. But right is right, and there's no ``risk'' involved in doing self=[super init] (self is nobody's ivar). About freeing: >>>>> /*These are macros to free things that (ultimately) rely on memory allocated for them (either through malloc or vm_allocate). The idea is to avoid dangling pointers at all times.*/ #define FFREE_MALLOC(p) (free(p),p=NULL) #define FREE_MALLOC(p) (p?FFREE_MALLOC(p):NULL) #define FFREE_FILE(p) (fclose(p),p=NULL) #define FREE_FILE(p) (p?FFREE_FILE(p):NULL) #define FFREE_PIPE(p) (pclose(p),p=NULL) #define FREE_PIPE(p) (p?FFREE_PIPE(p):NULL) #ifdef __OBJC__ #define FFREE_OBJECT(id) ([id free],id=nil) #define FREE_OBJECT(id) (id?FFREE_OBJECT(id):nil) #define FFREE_LIST(id) ([id freeObjects],[id free],id=nil) #define FREE_LIST(id) (id?FFREE_LIST(id):nil) #endif #ifdef NeXT #define FFREE_MEMORYSTREAM(p) (NXCloseMemory(p,NX_FREEBUFFER),p=NULL) #define FREE_MEMORYSTREAM(p) (p?FFREE_MEMORYSTREAM(p):NULL) #define FFREE_POPUPLISTBUTTON(id) ([[id target] free],[id free],id=nil) #define FREE_POPUPLISTBUTTON(id) (id?FFREE_POPUPLISTBUTTON(id):nil) #endif <<<<< Hoping this would be useful... Example of use: -free{ FREE_OBJECT(anObject); return [super free]; } Note that it is generally *not* correct to specify theId=[theId free], as everybody seems to think: if an object releases its reference to another object, it should not retain a pointer to it merely because some other object still has a reference (to spell it all out: if that other object does a successful free, the first object ends up with a dangling pointer). Does anyone have a non-hypothetical use for a return value of -free? [Other considerations suppressed.] Oh yes, this. If a .nib allocated a PopUpList aggregate (Button + PopUpList), how does the PopUpList get freed? The Button is in the View hierarchy, and a Window recursively frees its Views, but the Button doesn't know that it has a PopUpList as a target, so this will be a leak. Or not?

This could be accomplished by either - setting the selection's background to match the TextField's background. ..or by - turning selection highlighting off. I believe either of these two methods would achieve the desired result. The question is how to implement it. What I've tried, thus far, has not worked. Is there example code somewhere that shows how to do this? Any other suggestions? Thanks. -- Roberto SoftDesign, Inc.

I would like to have record objects that contain several char strings, and the contents of a single RTFD text field. The problem is, I'm coming up blank on how to get the RTFD text into an instance variable of my record class so it can be serialized or stored using the IXBlobWriting protocol. The only way I know to get the RTFD data out of the text object is via the writeRTFDTo: method, which writes onto an NXStream. At this point, what can I do? I can write the data to a file, which does me no good. I don't know the format or the length of the "serialized" RTFD data, so I can't get it out of the stream using NXRead or NXScanf. Is there some method of writing NXStreams into IXStore files that I'm unaware of? Or perhaps I'm going about this all wrong. Any clues or comments appreciated. Rich Ogata

From: ricardo@ughtas.pencom.com (Ricardo Parada) Newsgroups: comp.sys.next.programmer,comp.sys.next.advocacy,comp.sys.dec.micro,comp.sys.powerpc,comp.sys.dec Subject: OPENSTEP on Alpha OSF/1 and PowerPC Mach Date: 13 Dec 1993 04:55:18 GMT Organization: Pencom Sofware Message-ID: <2egsjm$h3u@digdug.pencom.com> Since NeXT Computer Inc. made the OPENSTEP announcement I have wondered what platforms are the easiest to get OPENSTEP up and running. Being NEXTSTEP implemented on top of Mach, those platforms that have Mach are the most likely to have OPENSTEP. IBM has Mach on PowerPC. DEC with OSF/1 on Alpha probably does, I'm not sure. Is there anyone out there that has had some experiences with OSF/1 on workstations with the Alpha chip? Does it have Mach 3.0? What areas specifically does the Mach 3.0 API and NeXT's Mach differ? I've done a lot of NeXT Mach programming but none Mach 3.0 programming. All the examples I have tried from my book "Programming under Mach" compile under NEXTSTEP for example. Are most of the differences transparent (i.e. BSD compatibility via a personality module as oppossed to BSD inside the kernel). I've read or heard (don't remember) that they differ in advanced features that are used by database implementors to increase performance (i.e. allowing for custom memory pagers for example as oppossed to Mach's default memory pager doing the paging). If DEC has Mach 3.0 already on their OSF/1 operating system then it would be smart of them to go quickly with an OPENSTEP implementation. Who cares about NT at this point. Really the only advantage I see is that you don't pay to run DOS/Windows programs. But if I'm getting OPENSTEP I don't care paying for SoftPC. It does a great job on the Intel platform, and eventually ALL the apps will be NEXTSTEP/OPENSTEP apps because they are nicer to use, highly integrated and very high quality. At least on NEXTSTEP they are. IBM doing the same thing with OPENSTEP makes sense to me too. Most of the Mach 3.0 documents that I have read have come from IBM so I guess they really like and appreciate Mach. It would make sense for them to also have OPENSTEP on their Mach. Besides the PowerPC platform is suppossed to be an open platform and run all kinds of operating systems (or enviroments, i.e. OPENSTEP). They are already doing NT on the PowerPC so why not OPENSTEP that has such a great programming object-oriented environment, better than anything I've seen. And it's hard to think of something better or more elegant than NEXTSTEP. If the Mach API that NEXTSTEP was implemented with is still present on the other Mach versions the it would be easy for vendors that already have Mach to get OPENSTEP up and running once they license the code from NeXT. If OPENSTEP includes the protocols such as drag and drop and filter services it would make the user environment feel just like NEXTSTEP. If they implement equivalents to Mail or the Workspace Manager one can still drag and drop a picture from Mail and have it converted to an appropriate format transparently by the filter service and put it right on a Diagram document for example. That would be amazing. "Advanced operating systems reaching the ease of use of the Macintosh and NEXTSTEP!" -- What I've always dreamed of. This is what really makes OPENSTEP attractive to me as a programmer and as a user. _______________________________________________________________________ Ricardo J.

It was created specifically to divert lengthy flame wars from .misc. Comp.Sys.Next.Announce Announcements of general interest to the NeXT community (new products, FTP submissions, user group meetings, commercial announcements etc.) The NEXTSTEP FAQs are posted here monthly as well. This is a moderated newsgroup, meaning that you can't post to it directly. Submissions should be e-mailed to next-announce@digifix.com where the moderator (Scott Anguish) will screen them for suitability. Comp.Sys.Next.Bugs A place to report verifiable bugs in NeXT-supplied software. Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. Comp.Sys.Next.Hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. Comp.Sys.Next.Marketplace NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. Comp.Sys.Next.Misc For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! Comp.Sys.Next.Programmer Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. The NEXTSTEP programmer FAQs are posted here. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. Comp.Sys.Next.Software This is a place to talk about [third party] software products that run on NEXTSTEP systems. Comp.Sys.Next.Sysadmin Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. related Newsgroups ------------------ Comp.Soft-Sys.Nextstep Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. Comp.Lang.Objective-C Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. Comp.Object Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original Comp.Sys.Next no longer exists--do not attempt to post to it.) Exception to the crossposting restrictions: announcements of usenet RFDs or CFVs, when made by the news.announce.newgroups moderator, may be simultaneously crossposted to all c.s.n.* newsgroups.

Basically, I want to add functionallity to an app merely but dragging and droping the menu cell on the Apps Menu in IB. Is this possible? This information will have to be saved inside the nib.... If you look at how IB's Menus.nib does things you will see what it just uses buttons and maps them to regular MenuCell instances. Because I want to wrap up the functionallity into a single object I need to be able to specify my own MenuCell subclass instance. Obviously, I can choose to make a custom object palette and use a regular menu cell (which is probably what I will have to do) but I'm curious to know if it is possible to palettize a menucell subclass and still be able to drag and drop it thru IB. I think it really depends on how IB creates it's menucells when you drag and drop. I fear the makeCellAt: will just be copying some predefined prototype or instanatiating a MenuCell class directly.

Basically, just remove the '\' from the three escaped characters. Those three escape sequences are not supported under ANSI C (mainly because they are not necessary). K&R (among other books) has a table of supported escape sequences somewhere, if you are interested in having a definitive list of escape sequences. Question: When the compiler encounters an unknown escape sequence, does it use '\' or the value of the 'scaped character? > Also, somewhere else in the program I get : > > x.h:68: warning: conflicting types for built-in function `strlen' > > Should I just cast the result of strlen to an int or is there > a common hack which is used ?

That's a joke! Message-ID: <2ehr5u$263@steffi.demon.co.uk> Today I learnt that for regular files digital librarian uses the workspace API when it encounters a filename extension that it doesn't recognise. So if you have opener it will locate .gz files or .Z files correctly. For instance, you could compress all your man pages providing you didn't use man (And then if you are using Tom's Christiansen's man.shar package you could have compressed man source and compressed cat files) The one area this doesn't work and IMHO: should work.. is in RTFD files. Because the directory name is visible in Librarian and not the actual RTF file's name. Librarian using the standard RTFD routines and explicitly looks for TXT.rtf in the RTFD wrapper. What I would like would be for it to recognise TXT.rtf.* and use the same workspace API that it does for regular RTF files. Actually in an ideal world DL would know how to process compressed files itself because when you use the workspace API which will invoke Edit.app (typically) you lose the standard DL hypertext window. This would allow me to compress all of NeXT's documentation (which will only be indexed once so compressing won't harm anything there) I think of that a considerable diskspace saving. But I guess harddrive prices are quite low at the moment. Any comments?

We definitely want our customers to be able to load their compiled functions into our environment. We are using a WATCOM C compiler on the Windows side. All we need to do is get a object file loaded and get its address. If anyone has encountered this problem, please contact me. Even if you gave up, that is good information.

This is in fact the spec, though an unfortunate one IMHO. It creates "surprises", which inevitably cause problems.

True, I misspoke calling it an ivar, but it is "owned" by the messaging runtime and ought to be considered const. If a superclass can throw away this instance and replace it, why must the new instance be of the same class? Reassigning self is effectively casting a structure pointer from another pointer with no guarantee that the underlying structures are the same. Also, as in +new mentioned above, the instance may already have been completely initialized and would be corrupted by initializing a second time. In fact, if a superclass is going to pull the instance out from under me, I would *expect* it to replace it with a fully initiaized object, and the "correct" initialization would be - init { id superResult = [super init]; if ( superResult != self ) return( superResult); initialize... return( self); } But I would also discourage the use of this convention, require it to be clearly documented, and just not mess with it in general.

If you have a choice, use delegation: it is easier to debug and it affords you a greater opportunity to reuse your code from one project to another. It also frees you from having to subclass a lot of the AppKit classes." Why is delegation easier? Mostly because it is documented better. Since we don't get source for the appkit classes, it can be hard to override a method - we don't know under what circumstances it is called, etc. However, the calling conventions of the delegate methods are fairly precisely defined in the docs, so delegate methods are very easy to write. (Of course, NeXT could have just written overridable methods with better documentation, or given us the sources...) Another bonus. If there were no delegation and you were to program a central controller object that coordinates the behavior of a lot of different library objects, you would probably use subclassing to implement a mechanism just like delegation anyway (to pass information to the central object whenever something interesting happens). So since delegation is built in, this kind of programming can be extra-easy. David

Well, OSF/1 is not bad. But I think one would want to do a native NEXTSTEP Mach port if possible - get it out the door quickly. And Dec isn't as tied to OSF/1 as Sun is to Solaris. Although, after the Solaris port, hopping to other OSes should be a managble (though still not easy) task. As for the machine itself, it would be an excellent hardware platform for NEXTSTEP.

The bug: say you've created a Text view inside the ScollView and you mess a lot with the fonts (while you've selected all text): the scrollers do not properly reflect their position in certain circumstances, but when you click on them they do again. The nuisance: in the nib file of ScrollViewDeluxe you need to swap the items in the matrix for the PageUpAndDownButton otherwise they appear in the wrong order in the scroller (note that this has already been done for the PageLeftAndRightButton).

I would like to know which way *you* would do that, the goal being to be able to develop both the complete and the demo version with minimal efforts. What would you do? Some suggestions follow, but I do not know which one I should choose: 1. Make symbolic links from the distribution version to the demo one, but develop separately some files (e.g. the one managing the preferences). DRAWBACKS: 1/ I don't want to be busy making links every time I add a file in the distribution project. 2/ It's fine until you have to modify a file in the distribution project which is symbolically linked in the demo project. 2. Same but subclass application so that it is DemoApplication now. This class manages the fact that it should terminate after a given delay. If a class has a behavoiour depending on the fact that it is running in demo mode, it can just do something like testing if NXApp is of the desired kind of class. DRAWBACKS: I'm sure some nice guy can break something like <if ([NXApp isKindOfClassNamed:"DemoApplication"])> by changing the string in the executable; but perhaps it will work if we test for <if ([NXApp isKindOf:[DemoApplication class]])>? 3.

In most cases, I find the C++/X examples to be VERY INELEGANT relative to the OC/NS equivalents. The current UR contains a DCE example showing how easy client-server programming is under DCE. I find this DCE example to be yet another inelegant "standard" solution that seems to be handled much nicer under NEXTSTEP. However, I have tried to implement an elegant DO implementation, but it doesn't work, so I guess that's not really too elegant :-) I'm sure I'm doing something wrong because this is my first DO attempt, so I'd like your help in debugging this. I initially ran this implementation in the same process (no DO) and it worked fine, so the problem should be in the DO implementation, not in the algorithm.

We opened the IB.proj file, and the system came up and told us this was an old-style project file, and gave us options for converting it. Great! So we built it and ran it, and it runs, but with two problems which don't appear in NS 2.1. (1) I'm using the RTF object from Garfinkel and Mahoney's book to occasionally send a light-grey character to the current text window. But in NS3.2, once I get a light grey character, they're all grey after that. What has changed since 2.1? (2) I have a separate object which creates and sets up results windows which the system writes data in. This works fine in 2.1, but in 3.2 I don't get any windows created, and all the text gets printed in my default window. So something else must have changed, but I don't know what. Anyone know of Appkit/IB changes which might cause these problems for a working NS2.1 app? I've included the code below. Thanks in advance, David Finton (1) Here's the method I use to access the RTF object. I think I added two methods for light and courier, which I include below: [self insertTextLite:buf to:textObj]; /* insert text, light gray */ /*-------------------------------------------------------------------- Insert text, but make the inserted text light gray instead of black This is called by addText when it gets a \half<ch> directive from lisp. The result is that <ch> is added to the text, but printed in light gray. This new version (6-23-93) uses the RTF object to send rich text to the textObj. Details from Garfinkel and Mahoney, p. 320 --------------------------------------------------------------------*/ - insertTextLite: (const char *)buf to: textDoc { id rtf; int length = [textDoc textLength]; [textDoc setSel:length :length]; rtf = [ [RTF allocFromZone:[self zone]] init ]; [rtf courier]; [rtf light:YES]; [rtf append:buf]; [rtf light:NO]; [textDoc replaceSelWithRichText:[rtf stream] ]; [rtf free]; [textDoc scrollSelToVisible]; [textDoc display]; return self; } ..... in RTF.m : ....... /*----------------------------------------------------------------+ | light: used by Circles to print omitted pc's in a lighter shade.| | Reference: Garfinkel & Mahoney, p. 315. --djf, 6-23-99 | +----------------------------------------------------------------*/ -light:(BOOL)flag { [self appendRTF: flag ?

From: robert@steffi.demon.co.uk (Robert Nicholson) Newsgroups: comp.sys.next.programmer,comp.lang.perl Subject: Building perl for NeXTSTEP : HERE'S HOW (LONG) UPDATED Date: 13 Dec 1993 22:29:20 -0000 Organization: me organized? That's a joke! Message-ID: <2eiqc0$1q8@steffi.demon.co.uk> I left one thing out of my recent recipe. (I had previous hacked Configure) to avoid having to do this so I didn't pick it up when I tested my rebuild. Once through change d_stdstdio='undef' TO d_stdstdio='define' in config.sh THANKS TO Matthew Seaman (Matthew.Seaman@dyson.ox.ac.uk) for picking this up. Here's the complete modified post. Apparently-To: david@alembic.com Apparently-To: tchrist@cs.Colorado.EDU Apparently-To: greg@afs.com Status: RO Postings asking how to build perl under NeXTSTEP come up very often in this group so I decided to put together this tutorial in order to alliviate this problem. NOTE: For Mr Christiansen please archive this and add a pointer in the FAQ. This is certified for NS3.1. Building PERL 4PL36 for NeXTSTEP can be a tricky business owing the some assumptions made by Configure and NeXT's /usr/include/ tree. Common problems are Configure finding dirent.h before dir.h and thus defining both i_dirent and i_sys_dir in config.sh The most common mistake is entering /usr/include when it asks for this path. If you do this Configure then attempts to see if you have certain header files in order to determine what language features to support. So for instance if you entered /usr/include, during Configure it attempts to locate grp.h using test -f /usr/include/grp.h This file doesn't exist there under the NeXTSTEP's include tree thus it is necessary to enter /usr/include/bsd when it asks for the include path. Here is a transcript from a Configure session. root:/Users/robert/archives/perl-4.036>Configure 9:35 Beginning of configuration questions for perl kit. First let's make sure your kit is complete. Checking... Looks good... Checking your sh to see if it knows about # comments... Your sh handles # comments correctly. Okay, let's see if #! works on this system... It does. Checking out how to guarantee sh startup... Let's see if '#!/bin/sh' works... Yup, it does. Checking echo to see how to suppress newlines... ...using \c Type carriage return to continue. Your cursor should be here--> This installation shell script will examine your system and ask you questions to determine how the perl package should be installed. If you get stuck on a question, you may use a ! shell escape to start a subshell or execute a command. Many of the questions will have default answers in square brackets--typing carriage return will give you the default. On some of the questions which ask for file or directory names you are allowed to use the ~name construct to specify the login directory belonging to "name", even if you don't have a shell which knows about that. Questions where this is allowed will be marked "(~name ok)". [Type carriage return to continue] Much effort has been expended to ensure that this shell script will run on any Unix system. If despite that it blows up on you, your best bet is to edit Configure and run it again. Also, let me (lwall@netlabs.com) know how I blew it. If you can't run Configure for some reason, you'll have to generate a config.sh file by hand. This installation script affects things in two ways: 1) it may do direct variable substitutions on some of the files included in this kit, and 2) it builds a config.h file for inclusion in C programs. You may edit any of these files as the need arises after running this script. If you make a mistake on a question, there is no easy way to back up to it currently. The easiest thing to do is to edit config.sh and rerun all the SH files. Configure will offer to let you do this before it runs the SH files. [Type carriage return to continue] Locating common programs... cat is in /bin/cat. cp is in /bin/cp. echo is in /bin/echo. expr is in /bin/expr. grep is in /bin/grep. mkdir is in /bin/mkdir. mv is in /bin/mv. rm is in /bin/rm. sed is in /bin/sed. sort is in /usr/bin/sort. tr is in /usr/bin/tr. uniq is in /usr/bin/uniq. Don't worry if any of the following aren't found... I don't see Mcc out there, offhand. bison is in /usr/local/bin/bison. cpp is in /lib/cpp. csh is in /bin/csh. egrep is in /usr/bin/egrep. I don't see line out there, either. nroff is in /usr/bin/nroff. perl is in /usr/local/bin/perl. test is in /bin/test. I don't see uname out there, either. yacc is in /usr/bin/yacc. Using the test built into your sh. Checking compatibility between /bin/echo and builtin echo (if any)... They are not compatible! You are probably running ksh on a non-USG system. I'll have to use /bin/echo instead of the builtin, since Bourne shell doesn't have echo built in and we may have to run some Bourne shell scripts. That means I'll have to use -n to suppress newlines now. Life is ridiculous. Your cursor should be here--> First time through, eh? I have some defaults handy for the following systems: 3b1 dnix isc_3_2_2 sco_2_3_2 sunos_4_0_2 3b2 dynix isc_3_2_3 sco_2_3_3 svr4 aix_rs fps mc6000 sco_2_3_4 ti1500 aix_rt genix mips sco_3 titan altos486 greenhills mpc sgi ultrix_1 apollo_C6_7 hp9000_300 ncr_tower solaris_2_0 ultrix_3 apollo_C6_8 hp9000_400 next solaris_2_1 ultrix_4 aux hp9000_700 opus stellar unisysdynix cray hp9000_800 osf1 sunos_3_4 utekv dec_osf1 hpux sco_2_3_0 sunos_3_5 uts dgux i386 sco_2_3_1 sunos_4_0_1 vax (You may give one or more space-separated answers, or "none" if appropriate. If your OS version has no hints, do not give a wrong version--say "none".) Which of these apply, if any? [none] next perl has manual pages available in source form. If you don't want the manual sources installed, answer 'none'. Where do the manual pages (source) go (~name ok)? [/usr/man/man1] /usr/local/man/man1 Hmm... Doesn't look like a MIPS system. Where are the include files you want to use? [/usr/include] /usr/include/bsd /usr/include/ctype.h: No such file or directory Looks kind of like a BSD system, but we'll see... Congratulations. You aren't running Eunice. It's not Xenix... Nor is it Venix... Some systems have different model sizes. On most systems they are called small, medium, large, and huge. On the PDP11 they are called unsplit and split. If your system doesn't support different memory models, say "none". If you wish to force everything to one memory model, say "none" here and put the appropriate flags later when it asks you for other cc and ld flags. Venix systems may wish to put "none" and let the compiler figure things out. (In the following question multiple model names should be space separated.) Which models are supported? [none] Use which C compiler? [cc] Some C compilers have problems with their optimizers, by default, perl compiles with the -O flag to use the optimizer. Alternately, you might want to use the symbolic debugger, which uses the -g flag (on traditional Unix systems). Either flag can be specified here. To use neither flag, specify the word "none". What optimizer/debugger flag should be used? [-O] Your C compiler may want other flags. For this question you should include -I/whatever and -DWHATEVER flags and any other flags used by the C compiler, but you should NOT include libraries or ld flags like -lwhatever. For instance, this would be a good place to specify -DDEBUGGING. To use no flags, specify the word "none". Any additional cc flags? [ -I/usr/include] (C preprocessor flags: -I/usr/include) Any additional ld flags (NOT including libraries)? [none] Checking for optional libraries... Found -ldbm. Found -lsys_s. Some versions of Unix support shared libraries, which make executables smaller but make load time slightly longer. On some systems, mostly newer Unix System V's, the shared library is included by putting the option "-lc_s" as the last thing on the cc command line when linking. Other systems use shared libraries by default. There may be other libraries needed to compile perl on your machine as well. If your system needs the "-lc_s" option, include it here. Include any other special libraries here as well. Say "none" for none. Any additional libraries? [-ldbm -lsys_s] Checking alignment constraints... Doubles must be aligned on a how-many-byte boundary? [2] The following questions distinguish the directory in which executables reside from the directory in which they are installed (and from which they are presumably copied to the former directory by occult means). This distinction is often necessary under afs. On most other systems, however, the two directories are the same. In which directory will public executables reside (~name ok)? [/usr/local/bin] In which directory will public executables be installed (~name ok)? [/usr/local/bin] In the following, larger digits indicate more significance. A big-endian machine like a Pyramid or a Motorola 680?0 chip will come out to 4321. A little-endian machine like a Vax or an Intel 80?86 chip would be 1234. Other machines may have weird orders like 3412. A Cray will report 87654321. If the test program works the default is probably right. I'm now running the test program... (The test program ran ok.) What is the order of bytes in a long? [4321] Checking to see if your C compiler can cast weird floats to unsigned Yup, it does. Now, how can we feed standard input to your C preprocessor... Maybe "cc -E" will work... Nope...maybe "cc -E -" will work... Yup, it does. Your (shared) C library seems to be in /lib/libsys_s.a. If the guess above is wrong (which it might be if you're using a strange compiler, or your machine supports multiple models), you can override it here. Your C library is where? [/lib/libsys_s.a] Extracting names from the following files for later perusal: /lib/libsys_s.a /usr/lib/libdbm.a This may take a while...done bcmp() found bcopy() found Checking to see if your bcopy() can do overlapping copies... It can. bzero() found Your sprintf() returns (int). vprintf() found. Your vsprintf() returns (int). chsize() NOT found crypt() found. readdir() found dirent.h found. Some sites have disabled setuid #! scripts because of a bug in the kernel that prevents them from being secure. If you are on such a system, the setuid/setgid bits on scripts are currently useless. It is possible for perl to detect those bits and emulate setuid/setgid in a secure fashion until a better solution is devised for the kernel problem. Do you want to do setuid/setgid emulation? [n] dup2() found fchmod() found fchown() found fcntl() found You can have filenames longer than 14 characters. flock() found getgroups() found gethostent() found getpgrp() found getpgrp2() NOT found getpriority() found htonl() found Your system has both index() and strchr(). Shall I use index() rather than strchr()? [y] isascii() NOT found killpg() found lstat() found memcmp() found memcpy() found Checking to see if your memcpy() can do overlapping copies... It can't. memmove() found memset() found mkdir() found msgctl() NOT found msgget() NOT found msgsnd() NOT found msgrcv() NOT found You don't have the full msg*(2) library. Do you wish to attempt to use the malloc that comes with perl? [n] ndbm.h found. dbm.h found. Looks like you have Berkeley networking support. sys/file.h defines the O_* constants... and you have the 3 argument form of open(). pwd.h found. rename() found rewinddir() NOT found rmdir() found seekdir() found select() found semctl() NOT found semget() NOT found semop() NOT found You don't have the full sem*(2) library. setegid() found seteuid() found setpgrp() found setpgrp2() NOT found setpriority() found setregid() found setresgid() NOT found setreuid() found setresuid() NOT found setrgid() found setruid() found shmctl() NOT found shmget() NOT found shmat() NOT found shmdt() NOT found You don't have the full shm*(2) library. Your stat knows about block sizes. Your stdio is pretty std. Checking to see if your C compiler can copy structs... Yup, it can. strerror() found symlink() found syscall() found Testing to see which of <time.h>, <sys/time.h>, and <sys/select.h> should be included, because this application wants: struct timeval struct tm ctime(3) declarations I'm now running the test program... Trying -DI_SYS_TIME Succeeded with -DI_SYS_TIME telldir() found Configure: /usr/include/bsd/signal.h: cannot open You have void (*signal())() instead of int. truncate() found vfork() found Checking to see if your C compiler knows about "volatile"... Yup, it does. wait4() found waitpid() NOT found What type are groups ids returned by getgid(), etc.? [gid_t] (The following only matters if you have getgroups().) What type are the group ids returned by getgroups()? [int] Checking to see how big your integers are... What is the size of an integer (in bytes)? [4] The perl package has some auxiliary files that should be reside in a library that is accessible by everyone. Where should these "private" but accessible files reside? (~name ok) [/usr/local/lib/perl] On some systems (such as afs) you have to install the library files in a different directory to get them to go to the right place. Where should the library files be installed? (~name ok) [/usr/local/lib/perl] Checking to see how many bits your rand function produces... How many bits does your rand() function produce? [31] Some installations have a separate directory just for executable scripts so that they can mount it across multiple architectures but keep the scripts in one spot. You might, for example, have a subdirectory of /usr/share for this. Or you might just lump your scripts in with all your other executables. Where will publicly executable scripts reside (~name ok)? [/usr/local/bin] Some installations must install scripts in a different directory than where they will eventually reside. On most systems they're the same directory. Where do you install publicly executable scripts (~name ok)? [/usr/local/bin] Generating a list of signal names... Signals are: ZERO HUP INT QUIT ILL TRAP ABRT EMT FPE KILL BUS SEGV SYS PIPE ALRM TERM URG STOP TSTP CONT CHLD TTIN TTOU IO XCPU XFSZ VTALRM PROF WINCH LOST USR1 USR2 Your stdio uses signed chars. What type are user ids returned by getuid(), etc.? [uid_t] Checking to see how well your C compiler groks the void type... Support flag bits are: 1: basic void declarations. 2: arrays of pointers to functions returning void. 4: operations between pointers to and addresses of void functions. It appears to support void to the level perl wants (7). Your void support flags add up to what? [7] Which compiler compiler (yacc or bison -y) will you use? [/usr/bin/yacc] We don't need to <fcntl.h> if we include <sys/file.h>. gdbm.h NOT found. grp.h found. netinet/in.h found. We'll be including <sys/file.h>. sys/ioctl.h found. utime.h found. varargs.h found. No vfork.h found. End of configuration questions. Creating config.sh... Hmm...You had some extra variables I don't know about...I'll try to keep 'em... Propagating recommended variable $libswanted... Propagating recommended variable $usemymalloc... If you didn't make any mistakes, then just type a carriage return here. If you need to edit config.sh, do it as a shell escape here: ! ------------- At this point you can edit config.sh by escaping to the shell. Thus far the following have been indirectly defined in config.sh i_utime='define' i_dirent='define' both of these should be "undef" and make sure i_sys_dir='define' Also because Configure looks for stdio.h in $usrinclude which now is /usr/include/bsd it will not find it because under NeXSTSTEP this exists in the /usr/include/ansi tree. So change. d_stdstdio='undef' TO d_stdstdio='define' Here's the rest of the transcript Doing variable substitutions on .SH files... Extracting Makefile (with variable substitutions) Extracting c2ph (with variable substitutions) Extracting cflags (with variable substitutions) Extracting config.h (with variable substitutions) Extracting h2ph (with variable substitutions) Extracting makedepend (with variable substitutions) Extracting makedir (with variable substitutions) Extracting x2p/Makefile (with variable substitutions) Extracting cflags (with variable substitutions) Extracting find2perl (with variable substitutions) Extracting s2p (with variable substitutions) Now you need to generate make dependencies by running "make depend". You might prefer to run it in background: "make depend > makedepend.out &" It can take a while, so you might not want to run it right now. Run make depend now?

I have received one response from a NeXT employee: The basic problem is that this code modifies a local proxy's private data without sending a message. (The reason it works in the same process is because the local proxy *is* the same object...) Therefore, the remote NXData object never gets "notified" that its contents are being changed. Since NXData contains no API to do this, you need to find a better way... One solution is to not share the resultData object, just get it back from the server. I changed your code to reflect this model: My original protocol that didn't work: - (NXData *)sumArrays:(NXData *)a :(NXData *)b into:(NXData *)c; The modified protocol that works: - (void)sumArrays:(in NXData *)a :(in NXData *)b into:(out NXData **)c; I had hoped that I could merely take a method that worked fine in a non-DO implementation, place its implementation in a server, and find out that "It Just Works..." Well, it doesn't in this case, I guess :-( The modified implementation allocates memory for "c" in the server and copies it out across the connection to the client. The client is thus responsible for freeing something that it didn't allocate which I don't like. I want the client to allocate memory for "c", pass it to the server, and for the server to return "c" to the client containing the result as my original protocol specified. Is this not possible using NXData? Must I create a different NXTransport-conforming container object to use to pass the arrays and the result array? If so, then DO isn't looking as elegant relative to DCE as I originally imagined :-( -- Art Isbell Cubic Solutions NeXT Registered Consultant NEXTSTEP software development and consulting NeXTmail: art@cubicsol.com Voice: +1 408 335 1154 USmail: 95018-9442 Fax: +1 408 335 2515

Suppose you have an abstract "Inspector" class that can be subclassed to inspect and edit something, or many things -- text, RTF, TIFF, database tables, whatever. It can even inspect parts of an object inspected by another Inspector, and it automatically notifies its parent Inspector of any changes it makes. (This isn't a contrived example. We're using something like this for our applications.) You want the application as a whole to coordinate and generate all Inspectors. But, since you've already written Inspectors to coordinate with each other, it's eaiest to coordinate them all with a Master Inspector, and then set it up as the Application delegate. If you didn't have delegation -- if you had to subclass Application -- you wouldn't have that option. You'd need to rewrite enough of the Inspector in your Application subclass to interact with other Inspectors (since ObjC has no multiple inheritance).

It has many updates and corrections and has several very up-to-date appendices on object- oriented methodologies and systems. While a new section on miscellaneous commercial systems and libraries is still in the works for completeness, this document may very well comprise the latest and most up-to-date collection of object-oriented systems and terms in the world today! There is also a potential upcoming merge with the new C++ Libraries FAQ. New noteworthy additions are the OO methodologies and OOA/OOD sections and ever expanding appendices. Future FAQs will contain a diff file. The FAQ is updated and posted monthly. Comments, suggestions, additions, updates, and new systems and site entries should be sent to rjh@geodesic.com. The FAQ is posted to the comp.object, comp.answers and news.answers newsgroups and is available via anonymous ftp from zaphod.uchicago.edu and rtfm.mit.edu, although new versions may take a short period of time to be installed.

Please send all comments, criticisms, etc. to me (Lucas Wagner) at lucas@blkbox.com. I have a product I developed over the summer named "Ex_Machina"... It began as a need to satisfy my own UNIX BBS needs (which was, at the time, on my Sun)... It is unlike any other software out there, truthfully. I really enjoy it; it's a nice product with a truly unique interface. One of the nice features about it is the fact that it has CompuServe-like forums (with their own message bases and file sections)... One can use "go words" (ie. go irc brings you to the IRC forum, where one can post messages relating to IRC, enter IRC, or download "netiquette" files, etc... It is very comfortable to use, and I have even made guidelines to make the interface seem standard all throughout the system. Lately, I had been thinking (after seeing requests of NeXT BBS systems on the nets), "What would happen if I tried to market this?" I have the ideas, the code, and the interface (a la Interface Builder) The code is in sh and C format, which is the problem. How can one market something which allows access to the code? But, I'd really like to develop it for the NeXT platform and fill the niche which no one has filled yet! I truly believe this system is superior to anything available out there. The interface is standard enough that a GUI can be formed to be used with it. So, I am looking for a company or an individual with programming skills who will go on an honest quest with me to get some decent BBS software up for the NeXT. There are many alternatives to the specifics of the agreement on how profits will be distributed, which will be determined at the response to this letter. I believe it should be on a 50/50 case in most instances out of fairness, with exceptions on both cases in certain situations (such as upgrades - an area where the company or individual should take more credit)... I, in turn, will market the product, answer all calls about technical support (bugs, etc.), and handle the rest. Again, there are many alternatives to this, so if this does not sound decent, then please, by all means, let me know and we can arrange something. I will go to any extreme for this to work -- the NeXT market is nice and small - it is crucial to snatch up each opportunity there is. I would like to find a company or an individual who would like to take a risk in developing a product. Thanks for your time. Please let me know - it would be great to generate some extra profit by finally completing this project, something which would be greatly beneficial to both of us. Scrapping something I've worked on for almost a year would be truly painful. Thanks for your time, Lucas -- -- Lucas C.

While it's not quite the same thing, I figure I'll mention it here just the same. I've found I rather like Sybase's scheme for error *reporting*. In this case, the client says to the server 'send all messages to this function of mine'. Then, when errors, warnings, or informational messages are generated, they get fired off immediately to this function. What can happen is that the client can then make one call to the server, and multiple messages will be generated and sent to this function to be processed before the original call returns. While Sybase doesn't do this, it seems like it would be straight forward to add in a class of error messages allowing the client/caller/whatever to advise on sticky situations. Thus, the message generator might report "I started parsing this file, and while it might be of the kind you specified, it looks like an old version to me. you SURE you want me to continue?" and the client/caller could say 'yeah' or 'no'. As I said, though, this says little about actually dealing with exceptions, or the like. Just a way of conveying information about errors. (david john burrowes)

Well, it doesn't in this case, I guess :-( I have taken Matt's explanation and written a simple NXData category that defines the method setData: which can be used to set data in an existing NXData object which will thus notify a remote NXData proxy that its data has changed. And guess what; "It Just Works!!" > The modified implementation allocates memory for "c" in the server and > copies it out across the connection to the client.

This showed how to "DO-ize" existing classes and was a good learning experience for me. However, this still seemed like a lot of work to implement a DO equivalent of the DCE demo. So my categorized NXData seems like a simpler solution, but it may have flaws I don't recognize. Another very valuable lesson Matt passed on was the need to recognize that DO apps may run across architectures with different byte orders, so byte order conversions for all data must be implemented, a rather painful process. How does DCE handle byte order differences? So here's my NXData category that I think makes NXData objects general containers capable of recognizing remotely when its local data has changed: @implementation NXData(SetData) - setData:(void *)theData { memcpy(data, (const char *)theData, size); return self; } Comments? -- Art Isbell Cubic Solutions NeXT Registered Consultant NEXTSTEP software development and consulting NeXTmail: art@cubicsol.com Voice: +1 408 335 1154 USmail: 95018-9442 Fax: +1 408 335 2515

If you look at their propaganda on NT, it looks like they musta read about Mach pretty carefully, and thought: "We can do that!" Writing their own version of anything is a bonus to them, because it allows them to be different from everyone, make more money selling bug-fix "upgrades" and they don't have to pay licensing fees. NeXTSTEP 3.2 is based on a 2.x version of CMU's Mach, with some changes made at NeXT. In CMU Mach 3.0, the pager, and possibly a few other remaining functions, were stripped from the kernel, leaving what is regarded as a microkernel. Though many people claim there is debate on what exactly constitutes a MicroKernel, most people seem to agree that the CMU Mach 3.0 falls within the general definition, and many even claim that it is the standard-bearer of the MicroKernel architecture. I've noticed a few things that lead me to speculate that NeXT is planning to move to a 3.x release of CMU Mach (possibly in NeXTSTEP 4.0 ?) 1. In the Driver Kit docs with NeXTSTEP 3.2, mention that drivers should run at the User level, (enables easier driver development and testing, as well as preventing a driver from crashing a kernel) but that this feature has not yet been implemented in the Driver Kit. --Assumption: this will be easier to implement under Mach 3.0. 2. In this week's InfoWorld, Steve Jobs is quoted in a small article about IBM's plan for the PowerPC. (Their plan? Encourage everyone to port their OS to the PowerPC, so that the chip can dominate the market, then blast them all off by shipping a Mach based, object oriented OS.) In this story, they claim that NeXT has a version of NeXTSTEP for the PowerPC that was designed to run on the NeXT RISC Workstation, which was to be based on dual PowerPC 601 's running in a Symmetric MultiProcessor architecture. --Assumption: SMP is easier to implement, and may offer performance advantages, with a leaner microkernel. 3. It has been widely reported that NeXT is developing their own object-oriented file structure, for possible inclusion in NeXTSTEP 4.0. Although NeXTSTEP already supports loadable file systems, there may exist reasons why a 3.x "lean" microkernel is superior to a 2.x "fat" microkernel for this project. I've never hacked a kernel, so I don't know what these might be, specifically. In general, it would seem that moving to a Mach 3.x microkernel might provide some advantages for future growth of the OS, but probably isn't necessary for survival just now. Any thoughts on this? Has anybody run across any other stuff in the Developer docs that might support/undermine this theory? Gary Longsine long0@ncc.centel.com

The resulting code will run slower since the volatile attribute informs the compiler that all references have to be reloaded from memory. Compiling with -g and withOUT -O will guarentee that all of the debugging information is available, and that all references to varaibles will be written back to memory at the end of a source line so gdb can be used to 'correctly' modify the content of ANY varaible.

To start with, DOs use NeXT's NetNameServer database for keeping track of the objects that have registered themselves with a specific name. The problem is that the NetNameServer database is local to each machine. It is not a distributed database. Each machine will respond to either a direct request for an objectNamed... or to a network broadcast request for the same information (if said machine has an object with the requested name). This presents a problem when you want ALL objects on the network with the same name. In order to even attempt this, you have to send out the broadcast request and then wait for responses. NeXT's current implementation of Distributed Objects has a default timeout of 15 seconds (can be changed) and will return either when it gets its first response or when the time is up. Reasonably, there could be an alternate version of the -connectToName:onHost: that would return a list of objects from machines that responded within the timeout period. Alternatively, it would be possible to implement a -connectToName:onHosts:<list of hosts> in a category of NXConnection that would go through the list of hosts and query each one. The down side would be that each individual -connectToName:onHost: could take up to 15 seconds if the machine is down (unless you wanted to get really fancy and thread each -connectToName:onHost: into its own thread). Unfortunately, there is no easy to determine <all hosts in the LAN except my own> without some sort of broadcast request. If they are all NeXTs and are registered in the same NetInfo database, then you could conceivably get the list of machines from there, but you can't really know that you have ALL of the machines. Even if you could know ALL of the machines on the network, or if know MOST is enough, determining if one of them is running a particular server process (or has a particular object) is not trivial because between the time that you decide that there are no servers up and running and the time that you actually start you own up, another machine could be doing the same thing. The question then arises: does it matter if more than one server is up? If yes, then there are several network algorithms for determining remote node states (as well as distributed agreement, mutual exclusion, 2PC, 3PC, etc...) Well, enough meaningless drivel...

Message-ID: <1993Dec15.043835.10851@almserv.uucp> Sender: usenet@almserv.uucp Organization: Fannie Mae Date: Wed, 15 Dec 1993 04:38:35 GMT A plea for enlightenment: I've noticed a few obscure references over the past year to potential or planned support for Objective-C in Borland's development tools for Windoze. Can anybody give me the straight poop on this? I might have imagined it... With Sun's recent announcement of OpenStep, I think it makes more sense than ever for us to consider Objective-C as an alternative to C++ for our Windoze app development. On the whole, our experience in keeping projects on schedule is better with Obj-C than C++. Much of that is due to the power of the kits and development environment in NEXTSTEP; but for the stuff I have to do on Windoze, is there a good toolset based on Obj-C? Now that Microsoft has come out with a market-leading C++ package to compete with Borland, does it make sense for Borland to graduate to the more powerful O-O paradigm of Obj-C? Is this available today? and if so, how does it compare to C++ in terms of kits, support for GUI foundation classes, etc? As you might have guessed, I have relatively little expertise in serious software development on Windoze. My company, however, has accumulated a wealth of experience with Borland C++, MS Visual C++, MS Visual BASIC, and a number of 4GLs. We're still looking for the Holy Grail of software architecture: a unified object model across all our Windoze and UNIX systems. Something that has potential to play with OpenStep would be appealing. Any constructive advice at this point would be much appreciated. -- Neele Johnston Email: neele@fnma.com Unix Technical Services Fax: (202) 625-4941 Fannie Mae, Washington, DC Phone: (202) 752-6061

I never ever want caps-lock on (not even when I'm writing all capital letters), and yet I often hit that alt-shift key combination by mistake. For instance, I'll start to do an alt-shift-someOtherKey, and then change my mind before hitting the other key. Suddenly everything's screwed up because the shift-lock is on when I didn't expect it to be. All alphalock does is ignore the alt-shift combination, so that it will never turn on shift-lock. -- Garance Alistair Drosehn = gad@eclipse.its.rpi.edu ITS Systems Programmer (handles NeXT-type mail) Rensselaer Polytechnic Institute; Troy NY USA

I have a panel with several thing on it, buttons, a popup list, a switch, a radio button. I load this panel separately for efficiency. I set the file's owner of this nib to be 'DebugInterface', a class with an outlet for the nib. i do the usual if(outlet == nil) [NXApp loadNibSection:"debug.nib" owner:self withNames:NO]; The problem is that some of the outlets for the panel buttons are set, and some are not. I rebuilt from scratch, checked again and again that the connections in ib are there. it just seems to make no difference. just before I load the nib (i only do it once of course), I break the program and print some of the outlets out. all are nil as they should be. on the statement right after I do the loadNibSection, I print the outlet that points to the nib out, it's set correctly. and SOME of the outlets for the panel are set, and some are not. I look again in ib and yes, they are all set. they all point to the same object, and the object has the proper outlets in the inspector. I reparsed the object to see if that would make a difference. The only possible problem I see (aha you say, here's where he's wrong!) is that I have an abstract superclass, PanelInterface, with a single outlet, panelNib, and a char*panelName. DebugInterface is a subclass of PanelInterface., and I will have several subclasses for different panels. In the subclasses init function, i do panelName = "debug.nib" and I link nibPanel to the nib. IB knows about both classes. In the inspector, panelNib is dimmed in the aspects inspector, but in connections it is shown as connected (and it's not dimmed). I suppose its dimmed because it's an inheriated outlet from it's parent and can't be affected there. I also looked inside the nib file and the list of outlets seems to be complete, (although they are in no apparent order). The actual code (in the panelInterface class) is: -loadNib { if(!nibPanel) { if([NXApp loadNibSection: nibName owner: self withNames:NO]) printf("loaded panel from class %s or class %s\n", [self name], [[self class] name]); else printf("Load of %s failed\n",nibName); [self nibLoaded]; } return self; } the result is the correct loaded panel from class DebugInteface or class DebugInterface. How can some of the nibs be set and not the others? what's set: nibs that point to: a button, a textfield, a button, and a popup list what's not set (nil) a button, a matrix of radio buttons, a formcell It seems I must be making some obvious mistake. anybody? thanks, nick

It looks like German.keymapping is NOT the problem. If you press Shift everything is ok.

Run IB under gdb to see where it's really crashing. I believe that message you're seeing just has to do with the fact that IB crashed while you were doing a drag and drop. Realize that the order of events are: load in your palette. IB sends an appropriate initFrame: to each of the subviews on the palette. If you have nonview objects, you have to tell the palette about them by associating a view object on the palette with each non-view object using: - associateObject:IBObjectPBoardType:with in the palette's finishInstantiate method. The palette then sends init to them. If you have corresponding setOutlet:sender methods, those get sent now. Then when you select a view on the palette to drag and drop, IB sends a write: to either the view or the object, depending on if the view is just acting as a handle for the object (as it is in your case). After the write: finishes, IB allocs up a new object of that type and does a read: on the stream that it just had the object write itself out to. After the read: completes, the object gets sent an awake msg to finish waking itself up. Note that init only gets called for the first instance of each object on the palette; after that it's write:, read:, and awake. The obvious mistake most people make is either forgetting to implement these or implememting them wrongly, since this may be the first time as NeXTSTEP programmers that they've had to deal with archiving objects.

A little history: Back in pre-3.0 days, when you built a class in IB and then had IB save out the template source code, for each outlet you defined named foo (say), it wrote out a little stub routine - setFoo:sender { return self; } The idea was that you would then add the appropriate bit of code like: - setFoo:sender { foo = sender; [foo setupSomeStuff]; return self; } The problem was that most people didn't really want to do more than just set foo = sender, so in 3.0, they changed a few things: IB didn't automatically write out the little setOutlet:sender code, and (here's what's probably biting you) IB would go in and magically set the outlets between your nib file's owner and the real nib file owner when it was loaded. The problem was what about people who did things the old way (for which there were good reasons, like the people that wanted to do some additional setup in that setOutlet: method)? Well, IB figured that if you implemented a setOutlet:sender method, you totally knew what you were doing, and it wouldn't automatically hook things up, figuring you knew what you where doing. In other words, if you have two outlets, frick and frack, and after loading your nib file, frick is connected but frack isn't, check to make sure that you don't have a - setFrack:sender method, and that if you do, make sure that the first line looks like this: - setFrack:sender { frack = sender; // whatever other code you already had return self; } Again, that might not be your problem, but I know this bit me awhile ago, and it wasn't that obvious at first blush... -- --> Michael B.

CS Dept, Ithaca NY 14853 Date: Wed, 15 Dec 1993 22:54:17 GMT Nextstep gurus! A plea for help! I'm stuck. I can't figure out how to implement a control that correctly passes the field editor to a cell. Can anybody explain how to implement a control that uses the field editor? What is the function of [Window endEditing:]? How about [Cell endEditing:]? For example, here's what I'm doing (it doesn't work) in my control: (on the right kind of mousedown..) ... editor=[window getFieldEditor:YES for:self]; if (editor) { [window endEditingFor:self]; /* Do I have to copy data here? initialize the editor? */ /* what does the following really do? how does it */ /* differ from the corresponding select:inView:... method? */ [selectedCell edit:&cellRect inView:self editor:editor delegate:self event:theEvent]; return self; } ... (when I get the textDidEnd:endChar: message..) ... /* Do I need to do this copying? */ length=[textObject byteLength]; theString=NXZoneMalloc([selectedCell zone],sizeof(char)*(length+1)); length=[textObject getSubstring:theString start:0 length:length]; theString[length]='\0'; [selectedCell setStringValueNoCopy:theString shouldFree:YES]; /* what does the following do? */ [selectedCell endEditing:textObject]; /* Do I need to empty out the text object here? */ /* this drawing below doesn't seem to do much */ [selectedCell drawSelf:&cellFrame inView:self]; ... As is, the field editor seems to drag its text along with it between different cells. Also, although the cells correctly turn black-on-white when being edited by the field editor, they don't seem to turn back to their regular color afterwards (although this may be a problem with some other code of mine). It's very difficult to program by experiment, especially since there are so many permuations of possible reasonable strategies that NeXT might have used to shuffle the field editor around. Is there a place I can find a correct and detailed description of how the field editor is really managed? Thanks very very much! David

However, under 3.1, background fetching was plagued with problems (bugs?) that I couldn't solve (or workaround). But by implementing a user-settable record limit, we were able to provide an escape for users. This was not an ideal solution because long records take much longer to fetch than short records, so using a record number limit might mean waiting for 3 or 30 seconds to reach the limit. However, after upgrading to 3.2 and recompiling, our app frequently crashes after cancelling a fetch when the record limit is reached. This is a nuisance, but it gave me a reason to look again at background fetching under 3.2. Background fetching seems to have improved under 3.2, but it's still troublesome. Regardless of which background mode is used, cancelling a fetch results in a recordlist that erroneously registers itself as modified. The only way I can correctly set recordlist's private _flags.isModified flag is by using the @defs hack to twiddle the flag directly :-( OK, so I can work around that bug, but using the DB_BackgroundStrategy results in the last record fetched overwriting the valid row 0 entry in the tableview. And worse, it frequently results in an endless loop of select statements being sent to the server upon fetch cancellation. Killing the app seems to be the only escape :-( And using DB_BackgroundNoBlockingStrategy occasionally results in the recordlist erroneously setting its isModified flag even after I've set it correctly. I can find no reasonable workaround except clearing out the recordlist and refetching :-( Has anyone been able to successfully implement a background fetching strategy under 3.2?

That's not accurate, to say the least. There's nothing in the OS that limits the sampling rates through the DSP's SSI port (except for the max throughput). DSP itself and DMA stream from DSP to host can be operated at ANY sampling rate. Limitation upto 44.1kHz has to do the hardwired rate out to the D/A converters. You might want to look at the old (Rel 1.0) app source code for RecordApp-4 demo app available at the archives. On sonata.cc.purdue.edu: /pub/next/1.0-release/source 39202 Feb 9 1990 RecordApp-4.tar.Z You probably have to tweak SSI port parameters to suit your DAT interface, but that should give you an idea. It should be pretty easy to record sound at 48kHz. Just that it won't be easy to play back the sounds via NeXT's built-in D/A without doing sample rate conversion. But then, you don't have to because you can play it out via your DAT interface at 48kHz. Also, MusicKit 4.0's DSPSerialPortDevice.h/m is generalized for all kinds of sampling rates including 48kHz.

You can see it there as a sig_die.c file before you make the library, as a sig_die.o relocatable, AND as _sig_die in the libF77.a symbol table. It appears there are no other symbols the loader can't resolve. -------------- What I didn't appreciate at the time of posting is what the function sig_die() does; it handles error exception, such as dividing by zero. Well there wasn't a huge response to this, but Michal Jaegermann suggested that perhaps switching the order in which the libraries were loaded would help. I only made a meager attempt to try a different ordering in the Project Builder's Libraries category, but couldn't see any way to get, say, library I77 loaded ahead of F77. By then something else was pressing on me, so I put this problem aside for a bit. Today I got back to it and, taking Michal's suggestion more seriously, tried the load process -- by hand -- from a command line in the Terminal window: cc -g -O -Wall -I./sym -arch i386 -ObjC -sectcreate __ICON __header Sola-2DFlow.iconheader -segprot __ICON r r -sectcreate __ICON app /usr/lib/NextStep/Workspace.app/application.tiff -o Sola-2DFlow.app/Sola-2DFlow i386_obj/SolaController.o i386_obj/VecFieldView.o i386_obj/Sola-2DFlow_main.o i386_obj/drawVector.o sola.o -lI77 -lF77 -lMedia_s -lNeXT_s ^^^^^ ^^^^^ (note switched F77 and I77) This ordering DOES NOT COMPLAIN about not finding _sig_die, so Michal was quite right. And, I can proceed, perhaps only by hand loading the final app, but no matter, I can proceed. Nonetheless, there ought to be a way to affect the order of libraries in Project Builder. And, after (finally) looking more seriously at the DevTools/ 02_ProjectBuilder chapter, I found the following remark under "shortcuts": "Control-dragging in a file list allows you to reorder the files. This can be especially important in dealing with libraries, since the file order determines the link order." Indeed, that solves the load problem in the easiest way. (I'll forgo telling you about other things I might have tried.) Dick Silbar WhistleSoft, Inc.

The difference is m68k vs intel. Thunder == Intel, Lightning == m68k. The name differs for each different "platform". Thunder and Lightning are for the English / European platforms. The Kanji release is Arashi(m68k) and Taifu(intel). Also, for those of you who still have 3.0 systems (when the current versioning scheme was first used), the release name (English / European) was "Hyper", and Kanji was "Yamato". (and to answer your next question... 3.1 and 3.2 use the same version names) just another useless factoid to fill your brain... :-) later, Erik

Organization: UCLA, Computer Science Department Message-ID: <1993Dec16.071102.12810@cs.ucla.edu> Date: Thu, 16 Dec 93 07:11:02 GMT Apparently-To: gnu-gcc-bug@uunet.uu.net Distribution: world Followup-To: gnu.gcc.bug,comp.sys.next.programmer I recently compiled both gcc-2.5.7 and libg++-2.5.2 under NEXTSTEP 3.2. I have encountered a problem while compiling the libg++-2.5.2 test programs (i.e. make check). It seems like a bug in gcc-2.5.7 dealing with inline base class member functions, but I am not sure. I have attached the compilation results for one of the test modules (libg++/tests/tString.cc). I configured both gcc-2.5.7 and libg++-2.5.2 with 'm68k-next-mach' as the target. I used the results from the gcc-2.5.7 'stage3' make (after I did a 'make compare') to compile libg++-2.5.2. I know the same module compiled with no problem in libg++-2.4 using gcc-2.4.5. Has anyone seen a similar problem ? Can someone try to duplicate this result. Thanks.

NXPort aPort = NXPortNameLookup(appname, machine); [myListener setSendPort:aPort]; [mySpeaker unhide]; Of course this is a little stinky for unhide in particular because the default Speaker class does not actually have an unhide method in it.

How about one that did the NX_LISTMODE thing, allowed you to re-order the column headings and have the rows automatically re-sort based on the first three columns, allowed for dynamic re-sizing of the row height and column width with simple click and drag semantics.

This is running on the Alpha. Moving to an out of kernel OS personality has a performance hit of about 30% with no obvious gain in functionality for a single CPU workstation. I believe OSF will have a version of OSF1.3 (their Mach 3.0 product) with the Server recompressed back into the microkernel for workstations. On MPP machines the microkernel architecture looks attractive. You may have computer nodes running say a microkernel with simply a pager server and some disk. The uK is there for message routing and for VM. Even the scheduler has been moved out of kernel recently. This is experimental. DEC's version OSF1 is based on Mach 2.5 but with the VM system from Ultrix. NeXT's version of Mach also diverges from vanilla (CMU/OSF) Mach in this and a number of other areas. With this in mind it is a less trivial task for NeXT to port to the Alpha using this work. Porting to the Snake was probably easier as vanilla Mach (2.5 and 3.0) already exists and would have been available to NeXT - should they have needed this. [ is it Mach or HP-UX based ?] From a user's viewpoint the Mach API hasn't changed much from 2.5 to 3.0. Just a general clean and fixup. NeXT would want to take the latest OSF version though, rather than the one with the CMU emulation library hack. >NT is based on a kernel of Microsoft's own design, kinda. >If you look at their propaganda on NT, it looks like they >musta read about Mach pretty carefully, and thought: >"We can do that!" I'm sure they did, but we all stand on each others shoulders. NT is quite different from Mach and they have had some good ideas such as (I believe) thread migration which may be adopted by the Mach folks. >NeXTSTEP 3.2 is based on a 2.x version of CMU's Mach, with >some changes made at NeXT.

I believe it's already in vanilla Mach 2.5 releases, it certainly was in OSFs. (we had a sequent running OSF1 both on 2.5 and 3.0) T think NeXT didn't support SMP with their version of Mach. >In general, it would seem that moving to a Mach 3.x >microkernel might provide some advantages for future >growth of the OS, but probably isn't necessary for >survival just now. I think one possible advantage is that Mach 3.0 has been ported to a very wide range of hardware. In OSF's experience moving the OS server (Unix. DOS, OS/2, VMS etc) is then a much simpler task. That is you recompile for the new architecture and go... just like any other user level program. If NeXT were already based on Mach3.0 they would find ports to Sparc, Snake and PowerPC much easier. The downside is that Mach 3.0 is not a very mature technology and there is a noticable performance hit. However IBM has staked it's PC future on Mach 3.0 - they are planning to offer OSF1.3, DOS and OS/2 all running on top of Mach (at the same time if you like). David.

The problem was that RecordList needs a GenericRecord to copy in order to stick data somewhere after a fetch; this GenericRecord is called the "prototype". The guys who originally wrote DBKit used a too-clever trick of occasionally using the first row in the RecordList as the prototype, so as to escape the overhead of generating a new one. (Consider that for a fetch of 1000 records they are going to make 1000 copies of this guy, and it seems like a pretty small savings compared to the headache.) I don't know why this works fine for normal fetches, actually. As I recall, you can trick the RecordList into generating a new prototype (or generate one yourself) by setting it's prototype to NULL. However, I'd strongly suggest you abort trying to do fetches in the background; it was never properly tested, and thus you're entering into a world of headaches. In general (as you should know, Mr. Multi-column Joins!) breaking new ground in DBKit is a pleasure to be avoided. -Wil Shipley Omni Development, Inc. DBKit consulting and boy do we love it mmm-hmmm

Date: Tue, 14 Dec 1993 18:40:29 GMT I am working on a relational database being retrieved from Sybase using relational joins between tables (relationships) to set up master-detail relationships and to retrieve these using DBRecordLists and custom DBFetchGroups. Now, here is the problem. In the DB-Kit documentation (new 3.2) as well as the Master-Detail example in the Concepts section (has anyone looked at this?) the way to retrieve a relationship is roughly as in the code here: ----------------------------------------------------------------- DBRecordList *masterDept = [[DBRecordList alloc] init]; DBRecordList *detailEmp = [[DBRecordList alloc] init]; .. DBValue *toEmpVal = [[DBValue alloc] init]; /* Create objects to store the desired entity and properties. We'll assume that db, a DBDatabase object, exists.*/ id dept = [db entityNamed:"Department"]; /* TABLE */ id toEmp = [dept propertyNamed:"toEmployee"]; /* REL'N */ .. /* Empty the List object and use it to hold the detail properties. */ [detailProps addObject:[[toEmp propertyValue] propertyNamed:"name"]; ^^^^^^^^^^^^^ ---------------------------------------------------------------------- This method does not exist within the DB-Kit. Headers or documented as a method. The program compiles then crashes when it gets to this statement with a `does not respond to - propertyValue' message. This is mentioned as the way to retrieve the entity referenced by the relationship elsewhere as well - in the DBQualifier docs. GIVE ME A BREAK How can I do this some other way? (get the entity for the relationship destination- I tried [toEmp entity] but that simply returns the base (root) entity). Maybe if NeXT worried more about providing a complete kit, people would start using it. Thanks for any comments or suggestions. Anyone been bitten by this? (Thanks, NeXT) Ruze

Sender: news@knoware.nl (News Account) Message-ID: <CI6oG1.n26@knoware.nl> Date: Fri, 17 Dec 1993 14:33:37 GMT Organization: PH Software Hi there, I am curious about how object click-detection is done with Display PostScript/NeXTSTEP. I am not a NeXT programmer, but i did some Mac programming a few years ago. The Mac Toolbox provids a datatype called "Region" which basically is a set of screen dots. Each QuickDraw drawing statement can add dots to a region of choice. A function PointInRegion returns whether a coordinate (mouse click) is whithin a certain region or not. Because the pixels in a region need not be contigious, in other words, there can be 'holes' in the 'clouds' of dots that make up a region, it allows for very nice selecting of irragular shaped objects, whithout the need of relying on 'handles' ( I mean the little black squares). For example, one could make an icon of a face of which the 'flesh'-parts are sensitive to mouse clicks, but the eyes and mouth (depicted as 'holes') are inactive. So my question is: does Display PS and/or NeXTSTEP provide something similar to Regions? If not, how is object selection with the mouse generally implemented ? Any answers or pointers to (ftp-able) literature are very welcome ! -henq ----------------------------------------------------------------------- ----- henk vantyen PH Software internet: henq@phsoft.knoware.nl 105, Oude Vest applelink: henq@phsoft.knoware.nl@DASNET# 2312XV LEIDEN fax:+31.71143828 The Netherlands ----------------------------------------------------------------------- ----- "You are entitled to my opinion"

They can take an arbitrary path and either a point or another path and check for intersections. A path can easily have as many holes in it as you wish. If you are going to get serious about NEXTSTEP programming, I recommend that you get the red book - PostScript Language Reference Manual, 2nd Edition - and the purple book - Programming the Display PostScript System with NEXTSTEP. There are also a couple of other good books on NEXTSTEP programming.

What I recall hearing is some people who said they saw Xox running on the NRW and said the windowserver ran on one CPU, everything else on the other. About as far from SMP as you can get. But hey, Openstep running on top of Solaris 2.x or HP-UX 10.0 will be able to do SMP fine, since those kernels will do it.

Object instantiation/freeing is not a big problem-- the allocator and any per-class initialization should be protected by a mutex (objc_setMultithreaded probably enables such a mechanism). In your application, you would have to add mutex protection for the class-level stuff (reference counting, shared instance initialization, etc...). The stickler is in the way the obj-c method caching mechanism works; if I understand it correctly (part of this is assumption from experience and examining the API/docs), a method is left uncached until the first time it is called. As well, one can force the cacheing of methods using parts of the objc-runtime API. Because of this, there is the potential that the cache could be modified at any time-- so, the runtime must AT LEAST protect itself from having two threads simultaneously updating the runtime. It would also be mondo bad for one thread to be caching a method while a second thread attempts to use the partially cached method. There are other points of contention: - poseAs: modifies the class hierarchy - lots of objc-runtime functions modify hierarchies/method tables - category addition modifies method tables --- All is not lost; you can achieve a performance gain in tight loops or commonly executed methods in both a single and multi threaded application by grabbing the pointer to the implementation of a method and calling it as a normal C function. If you do this, be aware of exactly what it is that you are sending to which instance of what class-- using the C function pointer means that you can easily "send" a method to an instance that does not implement that method. If the method reads/writes any instance variables, you are hosed. Also, be aware that if a subclass overrides a paticular method, a different function pointer is used for that method-- obvious, yes-- but it makes highly optimized implementations of methods like makeObjectsPerform: interesting.... have a nice day! -- b.bum <bbum@friday.com> | "blah blah blah" WhiteLight Systems, INC. | - someone somewhere

Problem with this approach is that I must "prime the pump" by getting the dbModuleInstance to attempt a bogus fetch in order to grab the binder. Sure, I can 'return NO' in the above delegate message for the bogus fetch attempt, thus aborting the fetch, but this is kludgy, IMO. The reason I want to get at the DBBinder instance is to preconfigure the fetch to ignore duplicate rows via: - setIgnoreDuplicateResults:(BOOL)val So, in essence I first have to "prime the pump" with a bogus fetch to get the binder, then configure the binder to ignore duplicates, then do the real fetch.

By poking around in the specs file of the /lib/m68k directory, it seems that the library libposix is to be substituted for libsys_s. At this point, we receive an ld message of: ld: Undefined symbols: _main _initialState _objc_msgSend _NXGetDefaultValue _NXRegisterDefaults objc_class_name_NXStringTable objc_class_name_NXBundle These seem to be defined in the file posixcrt0.o, which according to the specs file should be automatically referenced in the compile/link. Explicit reference to this file in the command line confirms this as duplicately defined symbols errors pop up. After much chagrine and hair pulling, we have not progressed much further. Can anyone succinctly explain how to effectively build posix-based applications from the command line? Any help or direction on this matter would be greatly appreciated. Jimmie Young NASA/JPL

Message-ID: <westesCID12y.Ipw@netcom.com> Organization: Mail Group Date: Tue, 21 Dec 1993 00:52:09 GMT When compiling source code that was not specifically targeted to NeXT, and when that code has a next option, I am wondering is it better to compile it with: make bsd or with: make next ? (Assuming of course that the options are named bsd and next :) The thought is that a lot of code floating around the net with a next option may have been compiled for Motorola versions of NeXT and would therefore not work under the Intel version. As a general case, should bsd be the preferred make target? -- Will Estes Internet: westes@netcom.com
Newsgroups: comp.sys.next.programmer From: jaime@afs.com (Jaime Guerrero) Subject: Bug using DBBinders Message-ID: <1993Dec20.213100.439@afs.com> Sender: jaime@afs.com Date: Mon, 20 Dec 1993 21:31:00 GMT I have been able to confirm a bug in DbKit that causes a memory exception violation deep inside DbKit when DBBinders are used extensively. Specifically, the binders are set with several properties, a qualifier, and sometimes a retrieve order. We don't use a container, but only process records one row at a time as they are retrieved. We neither set a record prototype nor associate ivars or selectors with properties, but rather get and set values to and from records exclusively by manipulating the DBValues returned by valueForProperty:. We use binders for fetching, updating, inserting, and deleting records. The problem seems to increase in occurrence when DBBinders are created and freed more frequently, rather than trying to reuse an existing DBBinder. Has anyone experienced similar problems with DBBinders? Posting or email would be appreciated. -- Jaime Guerrero "Verbing weirds language." Anderson Financial Systems Inc.

Date: Mon, 20 Dec 1993 00:04:03 GMT I've been experimenting with the profiler in NEXTSTEP 3.2 just lately, and have run into a problem which looks like a bug to me (but might just be a stupid human error). Does anyone have any thoughts or answers? To save net-bandwith, I'll merely summarize by saying: it looks to me like some methods are being reported as having been called twice as often as they actually were (i.e. I know it was called 100 times ,but the gprof output lists 200, and lists the functions and methods that the method calls as being called only 100 times). I can provide more information or gprof reports or whatever if anyone wants to see more. Obviously, I'd appreciate it the most if someone could explain to me why this is just a stupid human error, as that would allow me to get on with my work the quickest =) Thanks in advance david john burrowes davidjohn@kira.net.netcom.com

This post is made weekly, to help 'point' users to more NEXTSTEP information Topics include: comp.sys.next newsgroups related newsgroups comp.sys.next newsgroups mailing list ftp sites NeXTanswers comp.sys.next.* newsgroups -------------------------- Comp.Sys.Next.Advocacy This is the "why NEXTSTEP is better (or worse) than anything else in the known universe" forum. It was created specifically to divert lengthy flame wars from .misc. Comp.Sys.Next.Announce Announcements of general interest to the NeXT community (new products, FTP submissions, user group meetings, commercial announcements etc.) The NEXTSTEP FAQs are posted here monthly as well. This is a moderated newsgroup, meaning that you can't post to it directly. Submissions should be e-mailed to next-announce@digifix.com where the moderator (Scott Anguish) will screen them for suitability. Comp.Sys.Next.Bugs A place to report verifiable bugs in NeXT-supplied software. Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. Comp.Sys.Next.Hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. Comp.Sys.Next.Marketplace NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. Comp.Sys.Next.Misc For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! Comp.Sys.Next.Programmer Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. The NEXTSTEP programmer FAQs are posted here. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. Comp.Sys.Next.Software This is a place to talk about [third party] software products that run on NEXTSTEP systems. Comp.Sys.Next.Sysadmin Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. related Newsgroups ------------------ Comp.Soft-Sys.Nextstep Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. Comp.Lang.Objective-C Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. Comp.Object Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher. (The original Comp.Sys.Next no longer exists--do not attempt to post to it.) Exception to the crossposting restrictions: announcements of usenet RFDs or CFVs, when made by the news.announce.newgroups moderator, may be simultaneously crossposted to all c.s.n.* newsgroups.

If so, I used to use binders exclusively as you do (with 3.0). However, with both QuickBase and Sybase, and apparantly starting with 3.1, if the SQL that I send to the backend fetches character fields (i.e., SELECT Name, Address FROM CustTable, for example), then any attempt to retrieve the stringValue of the DBValue yields a memory exception. The problem also occurs when fetching some aggregates (forgot which). You've found a way around this? Nevin

However, DBValue has had a bug which has led to memory exceptions, especially when using a DBValue to store the value of a relationship property.

I did a trace and found that _display:: is called and that only the view which is the doc view gets a drawSelf:: message sent to it without any subviews of the doc view getting the drawSelf::. Hence, no subviews every draw themselves and I am left staring at an empty screen. I will assume that it is an error on my part but I have not been able to find anything I have done wrong. BTW, the subview of the doc view is drawing in the superview ([View drawInSuperview]) so the bounds and frame are both in the doc views coordinate system and it should get a drawSelf:: at the very least. Why is ClipView doing _display:: instead of the real display:: message? Obviously, _display:: is an undocumented method but it apparantly does not propagate the display down the view hierarchy? gregory

Message-ID: <1993Dec21.175543.6564@cc.usu.edu> Date: 21 Dec 93 17:55:43 MDT Organization: Utah State University I am having some very strange troubles from my TextField object. The object comes straight from the palette in IB. I am trying to set the text of the TextField object, with varying results. Before my controller object calls a method of a supporting object, it updates a textfield of what it is doing. The only problem is that the only text I am seeing is the last bit of text that sent, it is not updating the display as I change the text. Example: - start:sender { [textField setStringValue:"Here we go..."]; [otherObject doThis]; [textField setStringValue:"Doing more stuff..."]; [otherObject playWithThis: stuff]; return self; } The result would be the textField only showing "Doing more stuff", and it only updates that when the "start" method returns.

Date: 22 Dec 1993 01:10:04 -0000 Organization: me organized? That's a joke! Message-ID: <2f86pc$g8@steffi.demon.co.uk> The recent NaN thread proved very useful and it's good to see quality worthwhile discussion on something. I'm hoping this will provoke a similar response. Exceptions can provide a very elegant form of error handling, some what more flexible than [return nil] so I was wondering under what circumstances is it common to use exception handling? There are two parts to using exceptions NX_RAISE (and friends) and NX_DURING.... In particular what specific areas of NS work do you use them for? Typically I've followed the NeXT guidelines in that I will use them for archiving but that's really the only area I make use of them. For instance, why is it in some of the NeXT developer examples that the archiving is bracked by NX_DURING but there is an empty handler. (What does that acheive?) Why would you just want to ignore exceptions? I'm looking to explore this further in order to make full use of exceptions.

Similar mechinisms are usually used in larger bodies of code that need to protect themselves from errors, external, imagined, or from within another part of the code itself. They can allow a large program to keep running, even if a single module or piece fails. The HANDLER part is intended to allow for any necessary cleanup, and a possible re-raise. If a procedure does nothing that would need to be undone in an exception situation (such as allocating memory), and it believes that any failures that it might see are completely uninteresting to any calling routine (quite a common case for any top-level mthods in an object), then an empty HANDLER is perfectly reasonable - it simply swallows the exception. One general use of exceptions in a user-driven program is in the main event handling loop. A convenient bottleneck for global exception handling, the handler can print the error on the console and continue execution. The basic block is: while (running) { DURING while (running) { <<MAIN PROGRAM LOOP>> } HANDLER <<PRINT ERROR>> END_HANDLER } The dual loop is to avoid setting up and tearing down the exception handling every event. The stuff, which is usually implemented on top of setjmp/longjmp, isn't very lightweight. -- Scott Byer NeXTMail: byer@mv.us.adobe.com Adobe Systems Incorporated These are *my* opinions, and 1585 Charleston Road, P.O.

THANKS! For those of you that might run into the same problem, it seems that the window server can sometimes lag behind your application and not update the display. The solution was to use a function called NXPing() which basically forces your application to wait for the window server to catch up before continuing. I just added the NXPing() function after each setStringValue statement and everything worked great. For those interested, NXPing() documentation can be found in GeneralRef/02_ApplicationKit/Functions/AppKitFuncions.rtfd It was also suggested that I try sending the TextField a "display" message. This did not work though, but NXPing() did. Thanks again, John Zollinger slwdz@cc.usu.edu

When the program launch, it tries to find a file named /tmp/test. If it finds it, the file is open, if it does not find it, it is created and the method -updateIndexAtPath:forSender: is sent to the IXFinder instance. My question is about the -performQuery:atPath:forSender: method. Documentation for that method is found in "Protocols:IXFileFinderQueryAndUpdate", chapter 7, p. 137 of NeXTSTEP General Reference, Volume 2 or could be found using the Digital Librarian. The three (3) methods implemented by the sender of a Query or Uptade are written. These methods are - fileFinde:didFindFile: -fileFinder:didFindList: and -fileFinder:willAddFile: Depending of the sender given (self or nil) to the -performQuery:atPath:forSender:, the method will look at the local index (nil) or will make a long search (self). The queries are: within(FileName 'SomeName') within(FileType 'ps') ge(FileSize 0) The FileName on both the local search and the long search works. The FileType works only on the long search. Other attribute names (FileSize, UnixType etc.) don't work at all. So, the the following table give you some example of what work and what don't. 1 -performQuery:"within(FileName 'SomeName')" atPath:XYZ forSender:self OK 2 -performQuery:"within(FileName 'SomeName')" atPath:XYZ forSender:nil OK 3 -performQuery:"within(FileType 'ps')" atPath:XYZ forSender:self OK 4 -performQuery:"within(FileName 'ps')" atPath:XYZ forSender:nil NO 5 -performQuery:"gt(FileSize 1000)" atPath:XYZ forSender:self NO 6 -performQuery:"gt(FileSize 1000)" atPath:XYZ forSender:nil NO In the fourth case (within(FileName 'ps') and nil) the address of the returned IXPostingList is 0x0.

I suspect the button, when someone change its icon (or its alticon) to perform the following steps: 1-Go to the disk (in the .app or inside the Mach segment) and load the new image 2-Draw the image using the composite method. If the image is changed, the previous image is forgotten. So if the same image come back later, it will have to be reloaded. The composite methods plays with the image itself. It is very low level code that perform the drawing in the view. Changing the icon name is simpler to program but that change is coded in the view level and implies redrawing anyway.

No. This is *very* simple use of binders in an apparently ordinary, intended way- sending addProperty:, addRetrieveOrder:, setQualifier:, and selectWithoutFetching messages, then setNext messages within a loop until failure. The only interesting thing about the test program is that the creation and freeing of some DBBinders occurs within the body of another outer DBBinder's ongoing fetch loop. > If so, I used to use binders exclusively as you do (with 3.0).

The problem > also occurs when fetching some aggregates (forgot which). In the test program, it does retrieves the stringValue of DBValue objects (via valueForProperty:) for character columns, but the crash is occuring inside selectWithoutFetching. In other variations, for example, when no alloc'd DBBinders are freed (just for experimental purposes, mind you), selectWithoutFetching messages don't crash but still fail inexplicably.

NeXT generally did a good job fixing DBKit bugs for 3.2, but this is a new one that was introduced. I'll trade this one for some of those that were fixed because the workaround is pretty easy. Apparently, the fetchgroup doesn't know that the deletion of the last record hasn't been saved, so it thinks no records remain. But the recordlist knows that a change hasn't been saved. So in a delete method or an appropriate delegate method, implement something along these lines: if ([fetchGroup recordCount] == 0) { // 3.2 bug doesn't clear out the last deleted record, so force it.

The idea of exceptions is nothing NeXT-specific, you also find it in Ada and in Eiffel, so it might be useful to read in that literature. There is an intoduction to OOP using Eiffel by Bertrand Meyer which covers the concept of exceptions well. I use exceptions frequently because they allow me to write robust code without coding too much error handling: Assume a function A that calls a function B that calls C. Now in C something bad happens. If you do it the traditional way you would have to evaluate the return code of C in B and return from B indicating an error which you finally handle in A. The problem is that the error passing code in B easily triples the size/costs/complexity of the code. For example consider C to be the 'printf' library function: How often do you check the return value of it? Just imagine to write error handling code for each call of 'printf' which you are supposed to do to deliver crash safe code! The alternative is to raise an exception in C and have a handler in A. Now, even if you don't have to have any error handling code in B, you get to a well defined point in A (the exception handler) in case of a problem. Later you can still decide to fix some errors in B by writing a (nesteed) exception handler in B but you can defer that until your code and documentation are stable. So, when I start a new project I only install an error handling function for NeXT's top level handler using NXRegisterErrorReporter which informs the user that the last operation couldn't be executed and allows him to continue with the program. Later, when I feel I need to be more specific or I could even correct the problem I write some additional error handlers for the lower layers. I hope that gives you an idea. Any coments?

I even successfully used it under Release 2.X in my applications. Now I'm having trouble recompiling under 3.2, although I don't know if the story would have been any different under 3.0 or 3.1, since I didn't try before. I know I could probably just cheat and put "extern int errno;" anywhere in my source, but I would like to find out why I can't get my program to compile without the following warning: Controller.m: In method `getFileInfo:' Controller.m:345: `errno' undeclared (first use this function) Controller.m:345: (Each undeclared identifier is reported only once Controller.m:345: for each function it appears in.)

The short answer is no. We're only given a limited API to Mail.app (i.e. undocumented and unsupported) which has limitations (that API has been floating around for a while, I don't have it handy but if you can't get ahold of it let me know). The API allows you to open a compose window and set the from, to, etc fields and to fill the window with text. There's no way to add attachments but you can hack it by putting a filename on the pasteboard and then invoking the Mail/Document service with NXPerformService(). This all has several limitations, such as only being able to operate on a single compose window at once. If the user already has a compose window open, or if you open two of them, you're liable to clobber one or the other of them. Alternately you can hack the NeXTMail format (it's just a uuencoded compressed tar file with an index and attachments) and write your own object to send this directly to sendmail, thus circumventing Mail.app altogether. The DolphinKit from Dolphin Technologies has just such an object (note that this isn't an ad for DolphinKit and I have no affiliation with Dolphin Technologies, I am just passing on a bit of information). There have been rumors abound that we will be provided a "mail engine" in 4.0 that will do exactly what we want to do. But you know what they say about rumors. Randy

NO! NO! __STRICT_BSD__ is defined when compiling with the -bsd option. You should NEVER #define (or -D) it yourself! (Same for __STRICT_ANSI__, _POSIX_SOURCE, etc.) As a general rule, nearly all non-NeXT-specific UNIX source code "off the net" should be compiled with -bsd (this may entail minor additions to Makefiles, usually with -D definitions, but sometimes as part of CFLAGS). FSF/Cygnus "configure" scripts do not work properly under NEXTSTEP. You should do a setenv DEFS -bsd *before* running configure, and will probably _still_ need to fix Makefiles by hand. Older Larry Wall "Configure" scripts generally do not work properly under NEXTSTEP, but the exact tweaks necessary vary among packages. Why, you ask? Simple: the people who write configure scripts make the naive assumption that there is only One Right Way to do things on any given platform. NeXT's C compiler is flexible enough to support several different dialects of C and the standard libraries, as well as Objective-C, C++, and a combination of the two. Accordingly, the header files are heavily #ifdef'ed, and attempts to find out what's supported by grep'ing through .h files or nm's of library archives generate incorrect results. GNU configure does better than Larry Wall's because it runs the C compiler rather than trying to work around it, but without NeXT-specific knowledge, it usually arrives at self-contradictory conclusions and produces something that either fails to compile, compiles with warnings, or compiles but the executable doesn't work properly. -=EPS=-

Since DataPhile 2.0 shipped before NS 3.2, this was totally unpredictable. Even the person who made the change to the IXKIT was unaware of its adverse effects on ALL applications dependent upon the indexing kit. Stone Design and Pangea have isolated the main problem that is responsible for corrupting databases and destroying views. Basically any view or text field or entry list larger than 8K in size will trigger the bug. NeXT is aware of the problem, knows that it is theirs, and we await their fix. In the meantime, we have made available a patch program, PatchDP, for DataPhile 2.0 that allows it to use the 3.1 shared libraries rather than the ones in 3.2. This circumvents most of the problems, but we would still encourage you to take precautions, such as exporting regularly and often, until DataPhile 2.1 is released Q1 94. If you decide to use DP2.0 unpatched on NS3.2, review your databases for the potential problem areas mentioned above before logging out. In particular, the Cities entry list provided in your DataPhileAux.pkg should not be used. Also, follow the instructions for fixing finds in SEARCHING_DP. Basically, we recommend that you should either not upgrade to NS 3.2, or patch DP 2.0. The PatchDP program is available on the Internet at the following ftp site: ftp.cs.unm.edu, in directory pub/stone/DataPhile/NS_3.2-DataPhile_Workarounds.tar.Z sum NS_3.2-DataPhile_Workarounds.tar.Z 28557 65 If you cannot ftp, send email to info@stone.com with the subject "Send Patch - ASCII" or "Send Patch - NeXTMAIL" We are on holiday until January 3, 1994; but we will fill requests for the patch during the holidays.

It was created specifically to divert lengthy flame wars from .misc. Comp.Sys.Next.Announce Announcements of general interest to the NeXT community (new products, FTP submissions, user group meetings, commercial announcements etc.) The NEXTSTEP FAQs are posted here monthly as well. This is a moderated newsgroup, meaning that you can't post to it directly. Submissions should be e-mailed to next-announce@digifix.com where the moderator (Scott Anguish) will screen them for suitability. Comp.Sys.Next.Bugs A place to report verifiable bugs in NeXT-supplied software. Material e-mailed to Bug_NeXT@NeXT.COM is not published, so this is a place for the net community find out about problems when they're discovered. This newsgroup has a very poor signal/noise ratio--all too often bozos post stuff here that really belongs someplace else. It rarely makes sense to crosspost between this and other c.s.n.* newsgroups, but individual reports may be germane to certain non-NeXT- specific groups as well. Comp.Sys.Next.Hardware Discussions about NeXT-label hardware and compatible peripherals, and non-NeXT-produced hardware (e.g. Intel) that is compatible with NEXTSTEP. In most cases, questions about Intel hardware are better asked in comp.sys.ibm.pc.hardware. Questions about SCSI devices belong in comp.periphs.scsi. This isn't the place to buy or sell used NeXTs--that's what .marketplace is for. Comp.Sys.Next.Marketplace NeXT stuff for sale/wanted. Material posted here must not be crossposted to any other c.s.n.* newsgroup, but may be crossposted to misc.forsale.computers.workstation or appropriate regional newsgroups. Comp.Sys.Next.Misc For stuff that doesn't fit anywhere else. Anything you post here by definition doesn't belong anywhere else in c.s.n.*--i.e. no crossposting!!! Comp.Sys.Next.Programmer Questions and discussions of interest to NEXTSTEP programmers. This is primarily a forum for advanced technical material. The NEXTSTEP programmer FAQs are posted here. Generic UNIX questions belong elsewhere (comp.unix.questions), although specific questions about NeXT's implementation or porting issues are appropriate here. Note that there are several other more "horizontal" newsgroups (comp.lang.objective-c, comp.lang.postscript, comp.os.mach, comp.protocols.tcp-ip, etc.) that may also be of interest. Comp.Sys.Next.Software This is a place to talk about [third party] software products that run on NEXTSTEP systems. Comp.Sys.Next.Sysadmin Stuff relating to NeXT system administration issues; in rare cases this will spill over into .programmer or .software. related Newsgroups ------------------ Comp.Soft-Sys.Nextstep Like comp.sys.next.software and comp.sys.next.misc combined. Exists because NeXT is a software-only company now, and comp.soft-sys is for discussion of software systems with scope similar to NEXTSTEP. Comp.Lang.Objective-C Technical talk about the Objective-C language. Implemetations discussed include NeXT, Gnu, Stepstone, etc. Comp.Object Technical talk about OOP in general. Lots of C++ discussion, but NeXT and Objective-C get quite a bit of attention. At times gets almost philosophical about objects, but then again OOP allows one to be a programmer/philosopher.

Exceptions are the only reasonable way to return from a function or method call when a value cannot be returned. For example, consider a method such as "(BOOL)isFemale:(const char *)name". If the specified name does not exist, this function cannot return ANY value, because neither YES nor NO is correct; the correct result is *unknown*, which is inexpressible in a BOOL. So, it raises an exception which allows it to return without either a YES or NO value. Some people will argue that *any* function or method subject to failure *must* be able to represent that failure condition in its return value. But by employing exception handling, you can allow a function or method to be declared with a natural and simple return value interface, and take care of the truly exceptional cases with handlers, which provide an alternate return path of execution. This is particularly valuable when such functions or methods are typically embedded inside other function calls or messages, where the testing of failure would impede readability and simplicity. Consider: - (BOOL)isFemale:(const char *)name { id emp; emp= [x employeeNamed:name]; if ( emp == nil ) NX_RAISE( NOT_FOUND, "not found", NULL ); return [emp isFemale]; } - someMethod { NX_DURING // note how simple and natural this statement is, directly using BOOL type if ( [self isFemale:"Fred"] ) printf( "sex= Female" ); else printf( "sex= Male" ); NX_HANDLER printf( "'Fred' is not an employee\n" ); NX_ENDHANDLER } Over: typedef enum // must introduce a new data type that adds an error value { male, female, unknown } sexOrStatusCode; - (sexOrStatusCode)isFemale:(const char *)name { id emp; emp= [x employeeNamed:name]; if ( emp == nil ) return unknown; return [emp isFemale] ? female : male; } - someMethod { sexOrStatusCode status; // note clumsy use of special type and inability to directly use data type status= [self isFemale:"Fred"]; if ( status == unknown ) printf( "'Fred' is not an employee\n" ); else if ( status == female ) printf( "sex= Female" ); else printf( "sex= Male" ); } Note the clumsy need to create a new 3-state sex type to allow indication of failure. This type is only used in this context; actual sex variables are simple BOOLs because that type represents any sex completely. To answer your question, We use the exception handling facility extensively in our generic data container classes, which can contain data of any intrinsic C type. Unlike NeXT's Cell, however, if you ask for a value, i.e, the -(int)intValue, and the container contains a value inexpressible in that type, i.e. a large double, it raises an exception rather than returning an erroneous truncation. This is because the container's type, i.e. double, simply cannot be expressed as the requested type, i.e. an int, so the request must fail without returning. Likewise if you ask for a numeric value and the container contains a non-numeric string, an exception is raised because there is no true numeric value of the string. NeXT's Cell returns 0 in this case, but that is wrong because clearly there is no numeric value of "abc"- it is not a number! The use of exceptions can greatly simplify the readability of code, and allow much more natural use of function and method calls, and avoid the messy need to reserve part of a data range or create new types for failure indication. -- Jaime Guerrero "Verbing weirds language."

I thought someone else might find it useful. Here is the hard info on the book: Title: Object-Oriented Development, The Fusion Method Authors: Derek Coleman, Patrick Arnold, Stephanie Bodoff, Chris Dollin, Helena Gilchrist, Fiona Hayes, and Paul Jeremaes Publisher: Prentice Hall (C) 1994 ISBN: 0-13-338823-9 Price: 37.00 Pages: 313 I purchased this book from Computer Literacy Books, from thier Fall/Winter catalog. Thier order number is BT531923. Book Flap: Industrial software developers have recognized the need for a systematic, practical approach to the software development process. The Fusion method integrates and extends the best features of the most successful object-oriented approaches: OMT/Rumbaugh, Booch, CRC, and Objectory, providing a more direct route through object-oriented analysis and design to implementation. In Object-Oriented Development: The Fusion Method, the authors, a team of highly respected software engineers and researchers, show, step-by-step, how to make object-oriented methods understandable, manageable, and usable. The book features: o A self contained reference providing the necessary information to use Fusion on a real software project, including a summary of all process steps, a notation summary, and a manual for all notation syntax and semantics. o A realistic case study that clearly demonstrates how the method can be applied to real-world software projects. o How to effectively introduce object-oriented analysis and design on real projects, and how the Fusion method can improve the management of projects in a step-by-step, practical presentation. o A unique summary and assessment of leading object-oriented methods (OMT/Rumbaugh, Booch, CRC, and Objectory). The authors explain how Fusion relates to these important methods and the rationale behind it. -End of flap- The book starts from the beginning, not assuming that you know very much about OOP. Some experience would be helpful, but this book would even be good for someone that knows nothing about OOP. It describes how OOP differs from traditional programming, and what the benefits of OOP are. This book describes the methods for "Analysis, which uncovers the objects and classes in the system, describes relationships, and defines the operations that the system can perform", "Design, which decides how to represent the system operations by the interactions of related objects and how those objects gain access to each other.", and "Implementation, which encodes the design into a programming language." This book does not cover the available OOP languages, just the processes to take to get to coding. It is very well written and understandable, with good illustrations and examples. In general, I recommend it to anyone currently doing OOP programming, or even thinking about it. (I have no affiliation with the authors or publisher, I just like the book.)

The driver functions asyncronously. A user control/monitor program connects to the driver, sends it a mach_port on which it will receive data blocks, configures the driver for a DAQ session, arms the board for external triggers, then launches a thread to sit on the data port waiting for incoming messages of dataBlocks or status messages. My current problem is that no matter how I setup my mach message, for some reason it only maps the first page (8192 bytes) of my drivers data buffer into my user program. And sometimes it fails to map the buffer even though the msg_send was sucessful. I didn't realize I had a problem until I got past the simple tests and really gave my driver a moderate DAQ task (a single trigger block of 64kb of data in 1 sec). QUESTIONS: 1) Does the msg_simple=FALSE and msg_type_inline=FALSE handle all the details of mapping the vm pages between the two tasks, or do you have to also use the vm_write command to do the mapping as in the /NextDeveloper/Examples/Unix/LKSOutOfLineData example? Mine seemed to work fine up to a single vm page without any vm_write or vm_read, and it doesn't seem to solve this problem. 2) Are out-of-line data blocks limited to single vm pages, or can you out-of-line a pointer to as big a region as can be allocated? 3) Does the msg_type_name and msg_type_size fields in the msg_type_t type really do anything special, or could you always use MSG_TYPE_BYTE, 8 and just adjust the msg_type_number to correspond to the number of bytes in a data block? 4) Is there anything special about the KernelIOTask in regard to this between task mapping of vm regions? Here's how my driver allocates it's data buffer: (vm_allocate also worked) r = vm_statistics(kern_serv_kernel_task_port(), &vm_stats); threadData->bufferSize = threadData->samplesPerTrigger * sizeof(unsigned short); numPages = (threadData->bufferSize)/(vm_stats.pagesize)+2; IOLog(" ORIGbufferSize=%d numPages=%d\n" ,threadData->bufferSize,numPages); threadData->bufferSize = numPages * vm_stats.pagesize; IOLog(" NEWbufferSize=%d\n",threadData->bufferSize); threadData->mallocPtr = IOMalloc(threadData->bufferSize); if(!IOIsAligned(threadData->mallocPtr, vm_stats.pagesize)) { IOLog(" buffer not page aligned\n"); threadData->dataBuffer = IOAlign(unsigned short*, threadData->mallocPtr, vm_stats.pagesize); } else { IOLog(" buffer is already aligned\n"); threadData->dataBuffer = threadData->mallocPtr; } IOLog(" allocated buffer %d\n",(int)threadData->dataBuffer); here is the message structure I'm using: typedef struct { msg_header_t header; msg_type_t t1; int frameNum; int dataCount; /* No. of shorts in *data */ msg_type_t t2; unsigned short *data; } data_msg_t; and here is the code for creating the message and sending it out: dmsg->header.msg_type = MSG_TYPE_NORMAL; dmsg->header.msg_local_port = NULL; dmsg->header.msg_remote_port = threadData->dataPort; dmsg->header.msg_id = msgID; dmsg->header.msg_size = sizeof(data_msg_t); dmsg->t1.msg_type_name = MSG_TYPE_INTEGER_32; dmsg->t1.msg_type_size = 32; dmsg->t1.msg_type_number = 2; dmsg->t1.msg_type_inline = TRUE; dmsg->t1.msg_type_longform = FALSE; dmsg->t1.msg_type_deallocate = FALSE; dmsg->frameNum = threadData->frameNum; dmsg->dataCount = threadData->dataCount; if(msgID==DATA_BLOCK) { dmsg->header.msg_simple = FALSE; dmsg->t2.msg_type_name = MSG_TYPE_INTEGER_16; dmsg->t2.msg_type_size = 16; dmsg->t2.msg_type_number = threadData->dataCount; dmsg->t2.msg_type_inline = FALSE; dmsg->t2.msg_type_longform = FALSE; dmsg->t2.msg_type_deallocate = FALSE; dmsg->data = threadData->dataBuffer; } else { dmsg->header.msg_simple = TRUE; } r= msg_send((msg_header_t*)dmsg, MSG_OPTION_NONE,0); Thanks for any help, and please email responses.

Our goal was to write headers in such a way as to make them a substitute for separate class documentation. Our header directories would be indexed for Digital Librarian, and you would use the headers for class documentation. This approach would allow us to write and document code in a single step, in the hope that we would wind up with better documented code for ourselves (to improve internal operations) and instant documentation for customers (to save time). I have even gone to the trouble of creating a header file template, designed to look as much as possible like a standard NeXT documentation file, with appropriate stylistic conventions. Implementation files would use RTF primarily to take advantage of links, as the destination of links from the headers and to refer to appropriate files as needed. This would be for convenience only, and would not be mandatory. We have decided not to use RTF in headers in NS3.2 because IB will not parse them. This does not mean that we are disappointed with NeXT's RTF support as it is, just that it's not feasible for us to use it until IB is extended. Shortly before NS3.2 was released, I was in contact with NeXT about the RTF support, and they assured me that the only reason IB did not support RTF was because there wasn't enough time to squeeze it in before the release, and that if the reception was favorable enough then RTF support would be expanded as far as possible in the next release. We'd like to see full RTF support, and we're willing to wait for the next release to get it. Until then we have to do what makes sense for our development shop, so we will hold off on RTF source files for the time being.

Another area that requires attention is the ability to use rtf directives in Edit app's expansion dictionary. So hopefully somebody in the right place will hear this request. If Edit is to be the primary editor then it needs to allow programmers to express themselves by extending it's support for RTF. I believe that NeXT has the opportunity to, once again, distinguish themselves as the more flexible development platform by adding this support.

That only works for mu-law compressed output: if you think about it for a moment you'll realise that for 16-bit linear output you need to also: #include <architecture/byte_order.h> and for the output routine use: while (unpack_input(&code, dec_bits) >= 0) { sample = (*dec_routine)(code, out_coding, &state); if (out_size == 2) { #ifdef __LITTLE_ENDIAN__ /* Swap if this is a little-endian machine. */ sample = NXSwapShort(sample); #endif fwrite(&sample, out_size, 1, stdout); } else { code = (unsigned char)sample; fwrite(&code, out_size, 1, stdout); } } -- you're clearly too tired...

Newsgroups: comp.sys.next.programmer From: jfr@aspen.pdh.com (Jon F. Rosen) Subject: isKindOf: and isKindOfClassNamed: Message-ID: <CIrInx.DEu@pdh.com> Sender: news@pdh.com (USENET News Account) Organization: PDH, Inc. Date: Tue, 28 Dec 1993 20:38:21 GMT We have noticed what appears to be an anomaly in the implementation of Object's instance methods -isKindOf: and -isKindOfClassNamed:. The documentation says that Object's instance methods can also be sent to class objects. This is to avoid having to implement two sets of methods. This is a cool. It also gives as a justification the fact that it should be possible for either class or instance objects to determine their position in the class hierarchy. Then, in the -isKindOf: method, it screws this up royally by saying that when sent to a class object, this method returns YES only if the class object argument being checked is the Object class, otherwise it returns NO. Thus, [Window isKindOf:View] returns NO, which is not intuitive at all, whereas [aWindow isKindOf:View] returns YES. However, [Window isKindOf:Object] returns YES which is obvious and probably not very useful (all class objects are kinds of Object so why bother even checking?) Interestingly, -isKindOfClassNamed: works as one would expect (that is, [Window isKindOfClassNamed:"View"] returns YES). Stranger is that the documentation says that isKindOfClassNamed and isKindOf work the SAME except that one takes a class id and the other takes a class string name. Does anyone have any revealing info on why this weird set of rules is applied? My own speculation is that somewhere way back when, they screwed up isKindOf but couldn't really change it because code would break. So isKindOfClassNamed was added to fix the problem for class objects. Any hints? Thanks, Jon

One one hand, that's OK for now, because the vast majority of programs that make money are exactly "frumpy DP apps," and I have to buy a new car this week ;-). On the other hand, if the number and variety of shrinkwrap NEXTSTEP applications reaches critical mass, there will then be a sustainable market for games and other wizzy stuff, which NeXT should be prepared to support.

The user can drag icons from a window (local to the application) and drop them anywhere in the other window. This part works fine except the first time I try to execute the program after I have logged in, the accepting window doesn't accept anything. But after I drag an icon NOT local to the app. into the accepting window and release the mouse button, the window recovers and can accept local icons again. I think by dragging a non-local icon into the window I reset some parameter, but I have no idea which one it is. Second, when the accepting window is resized, some of the functions that were working properly screw up. For instance, before the window is resized, a single-click when Control is down would terminate a line-drawing session, but after, nothing can terminate it anymore. I know there are many NS experts out there reading this group. I would really, really appreciate it if any of you can help me out. It would save me a hell lot of time browsing through the doc.

Has anyone gotten this to work ? I have some hacks that work unless the button that was pushed on the PrintPanel was Preview. I can show these hacks, but I am sure that there must be a blessed way of doing this, or at least some better hacks than I have. If anyone has done this or has any clues, please let me know. I will post a summary as soon as I get something that works. Thanks, Ted Horst <ted@singlesrc.com> Single Source Systems, Inc.

I wanted this requirement recently. Let me tell you why. ChooseDirectories is rooted at OpenPanel which is a subclass of Save Panel hence I cannot use a SavePanel and only filter for directories only hence in order to filter for directories you have to use an OpenPanel.
