// $Log: DirWindow.m,v $
// Revision 1.4 97/07/08 11:53:33 sunshine
// v31: Worked around Cell's ClipView cache bug.
//
// Revision 1.3 97/06/10 05:14:32 sunshine
// v30: Synchronized with ScrollDir v29.4 for OPENSTEP.
// Reorganized to mirror structure of LazyScrollDir counterpart.
// Now uses -setTitleAsFilename:. Fixed bug: Wasn't taking directory
// sticky-bit into account when determining if file could be renamed.
// No longer misleadingly stat()'s file which soft-link points at.
// Ditched Message slot. Upgraded naming. Hard-links are now right-aligned.
//
// Revision 1.2 97/02/05 08:15:52 sunshine
// v29: Resync'd with LazyScrollDir (v13).
// Added 'writable' flag which prevents cmd-r from working on read-only
// directories.

// NOTE: USE_PRIVATE_ZONE
// When set to '1', this program will place each window in a separate
// NXZone and destroy the zone when the window is closed. However,
// the NEXTSTEP 3.3 Cell class caches ClipViews which it uses for editing
// scrollable cells. Unfortunately the caching code is buggy. It
// blindly allocates ClipViews from transient zones such as ours then
// caches and tries to re-use the ClipViews even after the originating
// zones are defunct. Hence the program crashes. Verification of this
// bug was obtained via disassembly of relevant portions of the AppKit.
// The OPENSTEP AppKit does not have this problem. Disassembly of the
// relevant OPENSTEP AppKit code reveals that the NSClipViews are
// allocated from a zone which is guranteed to stay around for the life
// of the application, NSDefaultMallocZone().
