* generic/tclFCmd.c (TclFileAttrsCmd): return the list of attributes
that can be retrieved without error for a given file, instead of
aborting the whole command when any error occurs.
* unix/tclUnixFCmd.c: added support for new file attributes and for
copying Mac OS X file attributes & resource fork during [file copy].
* generic/tclInt.decls: added declarations of new external commands
needed by new file attributes support in tclUnixFCmd.c.
* macosx/tclMacOSXFCmd.c (new): Mac OS X specific implementation of
new file attributes and of attribute & resource fork copying.
* mac/tclMacFCmd.c: added implementation of -rsrclength attribute &
fixes to other attributes for consistency with OSX implementation.
* mac/tclMacResource.c: fixes to OSType handling.
* doc/file.n: documentation of [file attributes] changes.
* unix/configure.in: check for APIs needed by new file attributes.
* unix/Makefile.in:
* unix/tcl.m4: added new platform specifc tclMacOSXFCmd.c source.
* unix/configure:
* generic/tclStubInit.c:
* generic/tclIntPlatDecls.h: regen.
* tools/genStubs.tcl: fixes to completely broken code trying to
prevent overlap of "aqua", "macosx", "x11" and "unix" stub entries.
* tests/unixFCmd.test: added tests of -readonly attribute.
* tests/macOSXFCmd.test (new): tests of macosx file attributes and
of preservation of attributes & resource fork during [file copy].
* tests/macFCmd.test: restore -readonly attribute of test dir, as
otherwise its removal can fail on unices supporting -readonly.

* macosx/tclMacOSXBundle.c: added extended version of the
Tcl_MacOSXOpenBundleResources() API taking an extra version number
argument: Tcl_MacOSXOpenVersionedBundleResources().
This is needed to be able to access bundle resources in versioned
frameworks such as Tcl and Tk, otherwise if multiple versions were
installed, only the latest version's resources could be accessed.
[Bug 736774]
* unix/tclUnixInit.c (Tcl_MacOSXGetLibraryPath): use new versioned
bundle resource API to get tcl runtime library for TCL_VERSION.
[Bug 736774]
* generic/tclPlatDecls.h:
* generic/tclStubInit.c: regen.
* unix/tclUnixPort.h: worked around the issue of realpath() not
being thread-safe on Mac OS X by defining NO_REALPATH for threaded
builds on Mac OS X. [Bug 711232]

* generic/tclStubInit.c (tclOriginalNotifier):
* mac/tclMacNotify.c (Tcl_SetTimer,Tcl_WaitForEvent):
* unix/tclUnixNotfy.c (Tcl_SetTimer,Tcl_WaitForEvent,
Tcl_CreateFileHandler,Tcl_DeleteFileHandler):
* win/tclWinNotify.c (Tcl_SetTimer,Tcl_WaitForEvent): Some linkers
apparently use a different representation for a pointer to a function
within the same compilation unit and a pointer to a function in a
different compilation unit. This causes checks like those in the
original notifier procedures to fall into infinite loops. The fix
is to store pointers to the original notifier procedures in a struct
defined in the same compilation unit as the stubs tables, and compare
against those values. [Bug 707174]

* generic/tclCmdMZ.c (Tcl_StringObjCmd STR_MATCH):
* generic/tclUtf.c (TclUniCharMatch):
* generic/tclInt.decls: add private TclUniCharMatch function that
* generic/tclIntDecls.h: does string match on counted unicode
* generic/tclStubInit.c: strings. Tcl_UniCharCaseMatch has the
* tests/string.test: failing that it can't handle strings or
* tests/stringComp.test: patterns with embedded NULLs. Added
tests that actually try strings/pats with NULLs. TclUniCharMatch
should be TIPed and made public in the next minor version rev.

* generic/tclInt.decls: added TclWinResetInterface
* win/tclWin32Dll.c (TclWinResetInterfaces):
* win/tclWinInit.c (TclpSetInitialEncodings, WinEncodingsCleanup):
add exit handler that resets the encoding information to a state
where we can reuse Tcl. Following these changes, it is possible
to reuse Tcl (following Tcl_FindExecutable or Tcl_CreateInterp)
following a Tcl_Finalize.

* generic/tclCompile.h: added prototype for TclCompileVariableCmd.
* mac/tclMacPort.h: removed incorrect <fcntl.h> definitions
and obsolete <stat.h> definitions.
* mac/tclMacChan.c: removed obsolete GetOpenMode() and replaced
associated constants with the <fcntl.h> analogues (they existing
defs were inconsistent with <fcntl.h> which was causing havoc when
Tcl_GetOpenMode was used instead of private GetOpenMode).
* mac/tclMacFCmd.c: removed GenerateUniqueName(), use equivalent
(and identiaclly named) routine from MoreFiles instead.
* mac/tclMacLoad.c: CONSTification, fixes to Vince's last changes.
* mac/tclMacFile.c:
* mac/tclMacTest.c:
* mac/tclMacUnix.c: CONSTification.

* generic/tcl.decls: added new macosx specific entry to stubs table.
* tools/genStubs.tcl: added generation of platform guards for
macosx. This is a little more complex than it seems, because MacOS
X IS "unix" plus a little bit, for the purposes of Tcl. BUT
unfortunately, Tk uses "unix" to mean X11. So added platform keys
for macosx (the little added to "unix"), "aqua" and "x11" to
distinguish these for Tk.
* generic/tcl.h: added a #ifnded RESOURCE_INCLUDED so that tcl.h
can be passed to the resource compiler.
* generic/tcl.h:
* generic/tclNotify.c: added a few Notifier procs, to be able to
modify more bits of the Tcl notifier dynamically. Required to get
Mac OS X Tk to live on top of the Tcl Unix threaded notifier.
Changes the size of the Tcl_NotifierProcs structure, but doesn't
move any elements around.
* unix/tclUnixNotfy.c: moved the call to Tcl_ConditionNotify till
AFTER we are done mucking with the pointer swap. Fixes cases where
the thread waiting on the condition wakes & accesses the
waitingListPtr before it gets reset, causing a hang.
* library/auto.tcl (tcl_findLibrary): added checking the
directories in the tcl_pkgPath for library files on macosx to
enable support of the standard Mac OSX library locations
* unix/Makefile.in:
* unix/configure.in:
* unix/tcl.m4: added MAC_OSX_DIR. Added PLAT_OBJS to the OBJS:
there are some MacOS X specific files now for Tcl, and when I get
he resource & applescript stuff ported over, and restore support
for FindFiles, etc, there will be a few more.
Added LD_LIBRARY_PATH_VAR configure variable to avoid having to set
all possible LD_LIBRARY_PATH analogues on all platforms.
LD_LIBRARY_PATH_VAR is "LD_LIBRARY_PATH" by default, "LIBPATH" on
AIX, "SHLIB_PATH" on HPUX and "DYLD_LIBRARY_PATH" on Mac OSX.
Added configure option to package Tcl as a framework on Mac OSX.
* macosx/tclMacOSXBundle.c (new): support for finding Tcl extension
packaged as 'bundles' in the standard Mac OSX library locations.
* unix/tclUnixInit.c: added support for findig the tcl script
library inside Tcl packaged as a framework on Mac OSX.
* macosx/Tcl.pbproj/jingham.pbxuser (new):
* macosx/Tcl.pbproj/project.pbxproj (new): project for Apple's
ProjectBuilder IDE.
* macosx/Makefile (new): simple makefile for building the project
from the command line via the ProjectBuilder tool 'pbxbuild'.
* unix/configure:

* generic/tclPlatDecls.h: regen

* unix/tclUnixThrd.c: Added stubs and implementations for
non-threaded build for the tclUnixThrd.c procs TclpReaddir,
TclpLocaltime, TclpGmtime and TclpInetNtoa.
Fixes link errors in stubbed & threaded extensions that include
tclUnixPort.h and use any of the procs readdir, localtime,
gmtime or inet_ntoa (e.g. TclX 8.4) [Bug 589526]

* generic/tclIntDecls.h:
* generic/tclStubInit.c:
* generic/tclUtf.c: added TclpUtfNcmp2 private command that
mirrors Tcl_UtfNcmp, but takes n in bytes, not utf-8 chars. This
provides a faster alternative for comparing utf strings internally.
(Tcl_UniCharNcmp, Tcl_UniCharNcasecmp): removed the explicit end
of string check as it wasn't correct for the function (by doc and
logic).
* generic/tclCmdMZ.c (Tcl_StringObjCmd): reworked the string equal
comparison code to use TclpUtfNcmp2 as well as short-circuit for
equal objects or unequal length strings in the equal case.
Removed the use of goto and streamlined the other parts.
* generic/tclExecute.c (TclExecuteByteCode): added check for
object equality in the comparison instructions. Added
short-circuit for != length strings in INST_EQ, INST_NEQ and
INST_STR_CMP. Reworked INST_STR_CMP to use TclpUtfNcmp2 where
appropriate, and only use Tcl_UniCharNcmp when at least one of the
objects is a Unicode obj with no utf bytes.

* generic/tclIntPlatDecls.h:
* generic/tclStubInit.c:
* mac/tclMacFCmd.c:
* mac/tclMacFile.c:
* mac/tclMacUtil.c: Modified TclpObjNormalizePath to be alias
file aware, and replaced various calls to FSpLocationFrom*Path
by calls to new alias file aware versions FSpLLocationFrom*Path.
The alias file aware routines don't resolve the last component of
a path if it is an alias. This allows [file copy/delete] etc. to
act correctly on alias files. (c.f. discussion in Bug #511666)

* generic/tclMain.c: Substantial rewrite and expanded documentation
of Tcl_Main to correct a number of bugs and flaws:
* Interactive Tcl_Main can now enter a main loop, exit
that loop and continue interactive operations. The loop
may even exit in the midst of interactive command typing
without loss of the partial command. [Bugs 486453, 474131]
* Tcl_Main now gracefully handles deletion of its master
interpreter.
* Interactive Tcl_Main can now operate with non-blocking stdin
* Interactive Tcl_Main can now detect EOF on stdin even in
mid-command. [Bug 491341]
* Added VFS-aware internal routines for managing the
startup script selection.
* Tcl variable 'tcl_interactive' is now linked to C variable
'tty' so that one can disable/enable interactive prompts
at the script level when there is no startup script. This
is meant for use by the test suite.
* Consistent use of the Tcl libraries standard channels as
returned by Tcl_GetStdChannel(); as opposed to the channels
named 'stdin', 'stdout', and 'stderr' in the master interp,
which can be different or unavailable.
* Tcl_Main now calls Tcl_Exit() if evaluation of [exit] in the
master interpreter returns, assuring Tcl_Main does not return. * Documented Tcl_Main's absence from public stub table
* Documented that Tcl_Main does not return.
* Documented Tcl variables set by Tcl_Main.
* All prompts are done from a single procedure, Prompt.
* Use of Tcl_Obj-enabled interfaces everywhere.
* generic/tclInt.decls (TclGetStartupScriptPath,
TclSetStartupScriptPath): New internal VFS-aware routines for
managing the startup script of Tcl_Main.
* generic/tclIntDecls.h:
* generic/tclStubInit.c: make genstubs
* generic/tclTest.c (TestsetmainloopCmd,TestexitmainloopCmd,
Tcltest_Init,TestinterpdeleteCmd):
* tests/main.test (new): Added new file to test suite that
thoroughly tests generic/tclMain.c; added some new test commands
for testing Tcl_SetMainLoop().

Added to internal stubs table. Tclcompiler (Tclpro project)
needs them if used as loadable package under Windows. Changed
signatures. We don't want to describe compiler internal
structures in "tclInt.h".

* win/tclWinFile.c (TclpObjStat): Now added the call to
'TclWinFlushDirtyChannels' to this function. I don't know where
my head was last thursday (2001-09-06), but the call was
actually added to 'TclpObjChdir', i.e. the implementation of
[cd]. Corrected this now. Thanks to Vince Darley for spotting
this.

* All of the changes below belong to TIP #10 [Tcl I/O Enhancement:
Thread-Aware Channels]. See also [Patch #403358] at SF.
* generic/tclIO.h (struct ChannelState, line 236f): Extended the
structure with a new field of type 'Tcl_ThreadId' to hold the id
of the thread currently managing all channels with this state.
Note: This structure is shared by all channels in a stack of
transformations.
* generic/tclIO.c (Tcl_CreateChannel, lines 1058-1065): Modified
to store the Id of the current thread in the 'ChannelState' of
the new channel.
* generic/tclIO.c (Tcl_SpliceChannel, lines 2265-2270): Modified
in the same manner as 'Tcl_CreateChannel' as the channel will be
managed by the current thread afterward.
* generic/tclIO.c (Tcl_GetChannelThread, lines 1478-1503):
* generic/tcl.decls (Tcl_GetChannelThread, lines 1504-1506): New
API function to retrieve the Id of the managing thread from a
channel. Implementation and declaration.
* generic/tclTest.c (TestChannelCmd, lines 4520-4532): Added
subcommand 'mthread' to query a channel about its managing
thread.

* Everything below belongs together, it fixes bug #123153.
* generic/tcl.h (line 342): A bit more explanation about the
default value for TCL_PRESERVE_BINARY_COMPATABILITY.
* generic/tcl.h (line 1208): Removed the macro 'Tcl_InitHashTable'
as it kills binary compatibility to 8.3 and earlier
versions. This is the main part of the patch/change.
* generic/tcl.decls (line 1469):
* generic/tclHash.c (Tcl_InitHashTable):
* generic/tclHash.c (Tcl_InitHashTableEx):
* generic/tclObj.c (Tcl_InitObjHashTable): Changed
'Tcl_InitHashTableEx' to 'Tcl_InitCustomHashTable'. This change
is more of an estethical nature, replacing the ubiquitous 'Ex'
suffix with a more meaningful name. The introduced binary
incompatibility is deemed acceptable as it is between alpha
versions. Updated callers.
* doc/Hash.3:
* unix/mkLinks: Changed 'Tcl_InitHashTableEx' to
'Tcl_InitCustomHashTable'.

* generic/tclDecls.h:
* generic/tcl.decls: added Tcl_SetMainLoop proc that allows people
to set a main loop that will run for tclsh.
* generic/tcl.h: added Tcl_MainLoopProc typedef
* generic/tclMain.c (Tcl_SetMainLoop, StdinProc, Prompt): new
StdinProc and Prompt static procs and Tcl_SetMainLoop stubs proc.
The first two handle a fileevent based prompt (taken from
tkMain.c). Tcl_SetMainLoop enables the interactive setting of a
main loop procedure. This enables Tk to be a loadable package.

* doc/StringObj.3: Added entry for Tcl_AttemptSetObjLength.
* generic/tclDecls.h:
* generic/tclStubInit.c: Regen'ed stubs files from new tcl.decls.
* generic/tcl.decls: Added stubs for the Tcl_Attempt* memory
allocators and for Tcl_AttemptSetObjLength.
* generic/tcl.h: Added #define's for attemptckalloc,
attemptckrealloc, which map to the Tcl_Attempt* memory allocators.
* generic/tclCkalloc.c: Added non-panic'ing versions of Tcl_Alloc,
Tcl_Realloc, etc.; these are called Tcl_AttemptAlloc,
Tcl_AttemptRealloc, etc. These are used by
Tcl_AttemptSetObjLength and the string obj append functions.
* generic/tclStringObj.c: Modified string growth algorithm to use
doubling algorithm as long as possible, and only fall back when
that fails. Added Tcl_AttemptSetObjLength, and modified
AppendUnicodeToUnicodeRep, AppendUtfToUtfRep, and
Tcl_AppendStringsToObjVA to support this.
