2004-12-29  Jeff Hobbs	<jeffh@ActiveState.com>

	* win/tcl.m4, win/configure: update MSVC CFLAGS_OPT to -O2, remove -Gs
	(included in -O2) and -GD (outdated). Use "link -lib" instead of "lib"
	binary and remove -YX for MSVC7 portability. Add -fomit-frame-pointer
	for gcc OPT compiles. [Bug 1092952, 1091967] Align LIBS_GUI with Tk
	head needs.

2004-12-29  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclDate.c: Regen
	* generic/tclGetDate.y (TclDatelex): Fixed a problem where a
	four-digit group with >=2 leading zeroes appeared to be a two-digit
	group, leading to misinterpreting the time 0012 as 1200. [Bug 1090413]
	* library/clock.tcl: Added code to interpret correctly months outside
	the range 01-12 as reduced modulo 12 with a corresponding adjustment
	to the year. [Bug 1092789]
	* tests/clock.test: Added regression test cases for the above two bugs
	* unix/Makefile.in: Added --no-lines to the 'bison' command line to
	* win/Makefile.in: help constrain the number of diffs in a cvs checkin

	Avoid sharing cmdName literals accross namespaces, and generalise
	usage of the TclRegisterNewLiteral macro. [Patch 1090905]

2004-12-20  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c: moved TclInitCompiledLocals to tclProc.c
	* generic/tclProc.c: new static InitCompiledLocals to allow for a
	single pass over the proc's arguments at proc load time (instead of
	two as previously). TclObjInterpProc() now allocates the
	compiledLocals on the tcl execution stack, using the new
	TclStackAlloc/Free functions.

2004-12-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInterp.c (Tcl_LimitSetTime, TimeLimitCallback):
	(TclLimitRemoveAllHandlers, TclInitLimitSupport): Set a timer event to
	trigger when the time limit runs out. All the time limit actually does
	is check to see if the time limit has been exceeded, but this is
	enough to fix [Bug 1085023].
	* generic/tclInt.h (struct Interp): Added a field to hold the token
	for the timer event handler associated with the current time limit.
	* generic/tclEvent.c (Tcl_UpdateObjCmd, Tcl_VwaitObjCmd): Add error
	message when limit exceeded.
	* tests/interp.test (interp-34.[89]): Check that time limits handle
	the two cases reported in [Bug 1085023]

	* generic/tclTimer.c (TclCreateAbsoluteTimerHandler): New internal
	function that allows setting a timer handler that will be triggered at
	(or after) a specific time instead of at some number of milliseconds
	in the future. This is a candidate for future exposure via a TIP.

	* generic/tclTest.c: Added two new functions to allocate memory from
	the execution stack (TclStackAlloc, TclStackFree). Added functions
	TclPushStackFrame and TclPopStackFrame that do the work of
	Tcl_PushCallFrame and Tcl_PopCallFrame, but using frames allocated in
	the execution stack - i.e., heap instead of C-stack. The core uses
	these two new functions exclusively; the old ones remain for backwards
	compat, as at least two popular extensions (itcl, xotcl) are known to
	use them.

	* generic/tclVar.c: changing the isProcCallFrame field of the
	CallFrame struct from a 0/1 field to flags. Should be perfectly
	backwards compatible.

2004-12-14  Don Porter	<dgp@users.sourceforge.net>

	* unix/configure.in: Added special processing to remove "$U" from
	libraries in the LIBOBJS value. This is an auto-make-ism we need to
	avoid. [Bug 1081541]

	* unix/configure: autoconf-2.57

2004-12-13  Don Porter	<dgp@users.sourceforge.net>

	* generic/tcl.h: Restored extern "C" guards so that C++ code sees
	function pointer typedef linkage consistent with earlier Tcl releases.
	[Bug 1082349]

	* generic/tclEncoding.c: Plugged some memory leaks. Thanks to Rolf Ade
	* generic/tclUtil.c:	 for reports and testing [Bug 1083082]

2004-12-13  Kevin B. Kenny  <kennykb@acm.org>

	* doc/clock.n: Clarify that the [clock scan] command does not accept
	the full range of ISO8601 point-in-time formats. [Bug 1075433]

2004-12-12  Miguel Sofer <msofer@users.sf.net>

	* generic/tclVar.c (TclArrayObjCmd - ARRAY_NAMES): leaking an object
	[Bug 1084111] - thanks to Rolf Ade.

2004-12-12  Miguel Sofer <msofer@users.sf.net>

	* generic/tclObj.c (TclSetCmdNameObj): special handling for fully
	qualified command names (as in fix [Patch 456668]).

2004-12-11  Miguel Sofer <msofer@users.sf.net>

	* generic/tclInt.h:
	* generic/tclNamesp.c: converting the static function
	GetNamespaceFromObj() to MODULE_SCOPE TclGetNamespaceFromObj().

2004-12-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tools/tcl.wse.in, unix/tcl.spec, win/README.binary, README:
	* win/configure.in, unix/configure.in, generic/tcl.h:
	Bumped version number to 8.5a3 to distinguish HEAD of CVS development
	from the recent 8.5a2 release.

2004-12-10  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCompile.c (TclInitCompiledLocals):
	* generic/tclCompile.h:
	* generic/tclInt.h:
	* generic/tclProc.c (TclObjInterpProc, TclCreateProc): optimised
	loops that initialise a proc's arguments and compiled local
	variables, removing tests from inner loops.

2004-12-10  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclInt.h: Move ensemble API decls here from tclNamesp.c

2004-12-09  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclNamesp.c (TclMakeEnsembleCmd, TclSetEnsemble*)
	(TclSetEnsemble*, TclFindEnsemble): Build an internal API for creating
	and manipulating ensembles; they can be deleted using the normal
	command-deletion API.

	* doc/Async.3: Reword for better grammar, better nroff and get the
	flag name right. (Reported by David Welton.)

2004-12-07  Don Porter	<dgp@users.sourceforge.net>

	* tests/unixInit.test (2.1-4): Added constraints so that when a value
	of TCL_LIBRARY is required for process initialization, we skip the
	tests that mess with that value.

2004-12-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	*** 8.5a2 TAGGED FOR RELEASE ***

	* unix/Makefile.in: add library/{tzdata,msgs} to dist target (kbk)

	* doc/foreach.n: Adjust tabs to be friendlier to some HTML
	converters. [Bug 1078760]

2004-12-06  Jeff Hobbs	<jeffh@ActiveState.com>

	* unix/tclUnixNotfy.c (NotifierThreadProc): init numFdBits
	[Bug 1079286]

	* doc/error.n, doc/SaveResult.3, doc/Thread.3: minor nroff typos

2004-12-06  Don Porter	<dgp@users.sourceforge.net>

	* tests/safe.test:	Trim auto_path to improve performance [1080039]

	* tests/msgcat.test:	makeFile/removeFile cleanup [1079117]

2004-12-04  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclEncoding.c:	Different fix for [Bug 1077005].
	* generic/tclEvent.c:	Broke apart TclpSetInitialEncodings() on
	* generic/tclInt.h:	Windows into TclpSetInterfaces(), that is
	* unix/tclUnixInit.c:	fundamentally essential, and the initialization
	* win/tclWinInit.c:	of the system encoding, which is not. Made
	the TclpSetInterfaces call part of TclInitSubsystems so it cannot be
	overlooked.

2004-12-03  Jeff Hobbs	<jeffh@ActiveState.com>

	* changes: updated for 8.5a2 release

2004-12-02  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclUtil.c (TclSetProcessGlobalValue): Handle the case where
	a ProcessGlobalValue might be assigned to itself.

	* generic/tclEncoding.c (MakeFileMap): Correct refcounting errors
	managing values returned by TclPathPart (with refCount of 1!) that led
	to a memory leak. [Bug 1077474].

2004-12-02  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c:  fix and new tests for [Bug 1074671] to ensure
	* tests/fileSystem.test: tilde paths are not returned specially by
	'glob'.

2004-12-02  Kevin B. Kenny  <kennykb@acm.org>

	* win/Makefile.in: Added a 'sed' in the setting of ROOT_DIR_NATIVE to
	compensate for a bug in cygpath (at least version 1.36) that leaves a
	trailing backslash on the end of the converted path.

2004-12-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInterp.c (Alias,Target,Master): Rewrote these so that the
	aliases that refer to an interpreter are stored in a list and not a
	hashtable (which was only ever a convenience, and forced the use of a
	global mutex to generate keys!) [FRQ 1077210]
	* generic/tclNamesp.c (numNsCreated): Moved into thread-local storage
	to remove a global mutex. [FRQ 1077210]

2004-12-01  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclUtil.c (TclGetProcessGlobalValue): Narrowed the scope of
	mutex locks.

	* generic/tclUtil.c:		Updated Tcl_GetNameOfExecutable() to
	* generic/tclEncoding.c:	make use of a ProcessGlobalValue for
	* generic/tclEvent.c:		storing the executable name. Added
	internal routines Tcl(Get|Set)ObjNameOfExecutable() to access that
	storage in Tcl_Obj, rather than string format.

	* unix/tclUnixFile.c:	Rewrote TclpFindExecutable() to use
	* win/tclWinFile.c:	TclSetObjNameOfExecutable to store the
	executable name it computes.

	* generic/tclInt.h:	Added internal stub entries for
	* generic/tclInt.decls: TclpFindExecutable and
	Tcl(Get|Set)ObjNameOfExecutable.

	* generic/tclIntDecls.h: make genstubs
	* generic/tclStubInit.c:

	* generic/tclCmdIL.c:	Retrieve executable name in Tcl_Obj form
	* win/tclWinPipe.c:	instead of string form.

	* unix/tclUnixTest.c:	Update [testfindexecutable] command to use new
	internal interfaces.

	* generic/tclEncoding.c:	Moved TclpSetInitialEncodings() call
	from Tcl_FindExecutable() into TclInitEncodingSubsystem(). This is
	important on Windows where it establishes whether the "ascii" or
	"unicode" set of system routines will be used, and that needs to be
	done earlier to support filesystem operations. [Bug 1077005]

2004-12-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/winDde.test: Rewritten to use tcltest2 features more
	thoroughly (reducing the [catch] count!) and fix the problem with
	winDde-6.1 being out of synch with the implementation.

2004-11-30  Don Porter	<dgp@users.sourceforge.net>

	* library/init.tcl ([unknown]): Restored the save/restore of the
	variables ::errorCode and ::errorInfo. This is needed when the
	[::bgerror] command is auto-loaded (as it is by Tk).

	Patch 976520 reworks several of the details involved with
	startup/initialization of the Tcl library, focused on the activities
	of Tcl_FindExecutable().

	* generic/tclIO.c:	Removed bogus claim in comment that encoding
	"iso8859-1" is "built-in" to Tcl.

	* generic/tclInt.h:	Created a new struct ProcessGlobalValue,
	* generic/tclUtil.c:	routines Tcl(Get|Set)ProcessGlobalValue, and
	function type TclInitProcessGlobalValueProc. Together, these take care
	of the housekeeping for "values" (things that can be held in a
	Tcl_Obj) that are global across a whole process. That is, they are
	shared among multiple threads, and epoch and mutex protection must
	govern the validity of cached copies maintained in each thread.

	* generic/tclNotify.c:	Modified TclInitNotifier() to tolerate being
	called multiple times in the same thread.
	* generic/tclEvent.c:	Dropped the unused argv0 argument to
	TclInitSubsystems(). Removed machinery to unsure only one
	TclInitNotifier() call per thread, now that that is safe. Converted
	Tcl(Get|Set)LibraryPath to use a ProcessGlobalValue, and moved them to
	tclEncoding.c.
	* generic/tclBasic.c:	Updated caller.

	* generic/tclInt.h:	TclpFindExecutable now returns void.
	* unix/tclUnixFile.c:
	* win/tclWinFile.c:
	* win/tclWinPipe.c:

	* generic/tclEncoding.c: Built new encoding search initialization on a
	foundation of ProcessGlobalValues, exposing new routines
	Tcl(Get|Set)EncodingSearchPath. A cache of a map from encoding name to
	directory pathname keeps track of where encodings are available for
	loading. Tcl_FindExecutable greatly simplified into just three
	function calls. The "library path" is now misnamed, as its only
	remaining purpose is as a foundation for the default encoding search
	path.

	* generic/tclInterp.c:	Inlined the initScript that is evaluated by
	Tcl_Init(). Added verification after initScript evaluation that Tcl
	can find its installed *.enc files, and that it has initialized
	[encoding system] in agreement with what the environment expects.
	[tclInit] no longer driven by the value of $::tcl_libPath; it largely
	constructs its own search path now, rather than attempt to share one
	with the encoding system.

	* unix/tclUnixInit.c:	TclpSetInitialEncodings factored so that a new
	* win/tclWinInit.c:	routine TclpGetEncodingNameFromEnvironment can
	reveal that Tcl thinks the [encoding system] should be, even when an
	incomplete encoding search path, or a missing *.enc file won't allow
	that initialization to succeed. TclpInitLibraryPath reworked as an
	initializer of a ProcessGlobalValue.

	* unix/tclUnixTest.c:	Update implementations of [testfindexecutable],
	[testgetdefenc], and [testsetdefenc].

	* tests/unixInit.test:	Corrected tests to operate properly even when
	a value of TCL_LIBRARY is required to find encodings.

	* generic/tclInt.decls: New internal stubs: TclGetEncodingSearchPath,
	TclSetEncodingSearchPath, TclpGetEncodingNameFromEnvironment. These
	are candidates for public exposure by future TIPs.

	* generic/tclIntDecls.h: make genstubs
	* generic/tclStubInit.c:

	* generic/tclTest.c:	Updated [testencoding] to use
	* tests/encoding.test:	Tcl(Get|Set)EncodingSearchPath.	 Updated tests.

2004-11-30  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl: Corrected the regular expressions that match a
	time zone to allow for time zones specified as +HH or -HH.
	* tests/clock.test: Added regression test case for the above issue.
	Thanks to Rolf Ade for reporting this issue [http://wiki.tcl.tk/13094]
	* win/tclWinDde.c (Tcl_DdeObjCmd): Corrected a typo that caused a
	compilation failure on VC++.

2004-11-29  Andreas Kupries <andreask@activestate.com>

	* win/Makefile.in (install-libraries): Brought entry '2004-10-26 Don
	Porter (Tcl Modules)' into the windows world, actually the
	win/configure buildsystem. The other windows buildsystems (.vc, .bc)
	still have to be updated as well.

2004-11-26  Andreas Kupries <andreask@activestate.com>

	* win/tclWinDde.c (ExecuteRemoteObject): Removed bogus semicolon found
	at the end of the header for the function definition, terminating it
	early and preventing a compile. This is likely a fix for '2004-11-25
	Donal'. I have to conclude that it is also unknown if the other
	changes to this file actually pass the testsuite. Running testsuite
	... They don't. winDde-6.1 fails. This is only a message discrepance,
	i.e. not too bad. Leaving resolution of that to Pat and Donal.

2004-11-26  Don Porter	<dgp@users.sourceforge.net>

	* library/auto.tcl (tcl_findLibrary): Made sure the uniquifying
	operations on the search path does not also normalize. [Bug 1072136]

2004-11-26  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/configure.in: Simplify the code to check for correctness of
	strstr, strtoul and strtod.
	* unix/tcl.m4 (SC_TCL_CHECK_BROKEN_FUNC): Split a complex stanza out
	of configure.in into its own function. Also force it to do the right
	thing with cacheing of results of AC_TRY_RUN to deal with issue raised
	in [Patch 1073524]

	* doc/foreach.n: Added simple example. [FRQ 1073334]

2004-11-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclProc.c (TclObjInterpProc):	    Make it so that only
	* generic/tclIndexObj.c (Tcl_WrongNumArgs): [proc] instances do
	* tests/indexObj.test (indexObj-5.7):	    quoting of their first
	arguments, so keeping [Bug 942757] fixed and making [Bug 1066837] be
	fixed as well. Done with a load of #ifdef-ery because this hack is so
	ugly nobody should keep it around once Itcl's fixed.

2004-11-25  Reinhard Max  <max@suse.de>

	* tests/tcltest.test: The order in which [glob] returns the file names
	is undefined, so tests should not depend on it.

2004-11-25  Zoran Vasiljevic <vasiljevic@users.sf.net>

	* doc/Thread.3:
	* doc/Notifier.3: Added changes from the core-8-4-branch

2004-11-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/dde.n: Synchronized the documentation of the commands with the
	header of the docs and what the package actually does. Thanks to
	Andreas Kupries for spotting this.
	* win/tclWinDde.c (Tcl_DdeObjCmd): Much cleanup of argument parsing
	code.

2004-11-24  David Gravereaux <davygrvy@pobox.com>

	* generic/tclPort.h: Relative include of tclWinPort.h returned as it
	was requiring me set -I$(tcl_root)/win for my extensions that need to
	include tclInt.h and doesn't appear to serve any purpose for windows
	builds.

2004-11-24  Kevin B. Kenny  <kennykb@acm.org>

	* unix/tcl.m4 (SC_ENABLE_THREADS): Corrected bad check for 3-argument
	readdir_r [Bug 1001325].
	* unix/configure: Regenerated.
	* unix/tclUnixNotfy.c: Corrected all uses of 'select' to manage their
	masks using the FD_CLR, FD_ISSET, FD_SET, and FD_ZERO macros rather
	than bit-whacking that failed under Solaris-Sparc-64. [Bug 1071807]
	* win/tclWinInit.c (TclpInitLibraryPath): Removed unused vars 'pathc'
	and 'pathv' that caused compilation problems on VC++ with
	--enable-symbols.

2004-11-24  Don Porter	<dgp@users.sourceforge.net>

	* unix/tcl.m4 (SC_ENABLE_THREADS): Corrected failure to determine the
	number of arguments for readdir_r on SunOS systems. [Bug 1071701]

	* unix/configure:	autoconf-2.57

	* generic/tclCmdIL.c (InfoVarsCmd):	Corrected segfault in new
	* tests/info.test (info-19.6):	trivial matching branch [Bug 1072654]

2004-11-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tools/man2html.tcl, tools/man2html1.tcl: Update to use Tcl 8.4.
	* tools/man2html2.tcl: Fix broken .SS handling.

2004-11-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/Makefile.in: Add (commented-out) code to integrate tclConfig.h
	into the dependency tree and 'make distclean'. [Bug 1068171]

	* generic/tclResult.c (Tcl_AppendResultVA): Remove call to
	Tcl_GetStringResult to speed up repeated calls to Tcl_AppendResult
	with the side effect that code that wants to access interp->result
	should always call Tcl_GetStringResult first. See [Patch 1041072]
	discussion for more details.

2004-11-22  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_TCL_64BIT_FLAGS): Define HAVE_TYPE_OFF64_T only when
	off64_t, open64(), and lseek64() are defined. IRIX 5.3 is known to not
	include an open64 function. [Bug 1030465]

2004-11-22  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_ENABLE_THREADS): Check for a 2 argument version of
	readdir_r that is known to exists under IRIX 5.3.
	* unix/tclUnixThrd.c (TclpReaddir): Use either 2 arg or 3 arg version
	of readdir_r. [Bug 1001325]

2004-11-22  Don Porter	<dgp@users.sourceforge.net>

	* unix/tclUnixInit.c (TclpInitLibraryPath): Purged dead code that used
	* win/tclWinInit.c (TclpInitLibraryPath):  to extend the "library
	path". Search path construction for init.tcl is now done within the
	[tclInit] proc.
	* generic/tclInterp.c:	Restored several directories to the search
	* tests/unixInit.test:	path used to locate init.tcl within [tclInit].
	This change does not restore any directories to the encoding search
	path, so should still avoid the price of an unreasonably large number
	of filesystem accesses during encoding initialization at startup
	[Bug 976438]

2004-11-22  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c: fix and new test for [Bug 1043129] in the
	* tests/fileSystem.test: treatment of backslashes in file join on
	Windows.

2004-11-21  Don Porter	<dgp@users.sourceforge.net>

	* doc/AddErrInfo.3:	Typo corrections (Thanks Daniel South).
	* doc/interp.n:

2004-11-19  Don Porter	<dgp@users.sourceforge.net>

	* doc/AddErrInfo.3:	Docs for Tcl_(Get|Set)ReturnOptions. [TIP 227]

	* doc/AddErrInfo.3:
	* doc/Async.3:		Documentation updates to replace references
	* doc/BackgdErr.3:	to global variable ::errorInfo and ::errorCode
	* doc/SaveResult.3:	and to the ::bgerror command with references
	* doc/after.n:		to their preferred replacements, the
	* doc/bgerror.n:	-errorinfo and -errorcode return options,
	* doc/error.n:		the Tcl_*InterpState routines, and the
	* doc/exec.n:		[interp bgerror] command.
	* doc/exit.n:
	* doc/fileevent.n:
	* doc/interp.n:
	* doc/return.n:
	* doc/tclvars.n:
	* doc/update.n:

	* tests/unixInit.test: Removed "knownBug" constraints to prompt bug
	fixing before 8.5a2 release.

2004-11-19  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Makefile:
	* unix/configure.in:
	* unix/tclUnixInit.c (MacOSXGetLibraryPath): changed detection of tcl
	framework build when determining tclLibPath from overloaded
	TCL_LIBRARY to configuration define TCL_FRAMEWORK. [Bug 1068088]

	* unix/configure: autoconf-2.57
	* unix/tclConfig.h.in: autoheader-2.57

2004-11-18  Don Porter	<dgp@users.sourceforge.net>

	* doc/SaveResult.3:	Documentation for Tcl_*InterpState (TIP 226).

	* generic/tclEvent.c (HandleBgErrors):	Simplified program flow.

	* tests/basic.test:	Updated functional (not testing) uses of
	* tests/io.test:	[bgerror] to make use of [interp bgerror].
	* tests/socket.test:
	* tests/timer.test:

	* tests/interp.test (interp-36.*):	[interp bgerror] tests.

	* generic/tclInterp.c:	Corrected [interp bgerror] error messages.

2004-11-18  Reinhard Max  <max@suse.de>

	* unix/tcl.m4 (SC_CONFIG_MANPAGES): Applied an improved version of
	* unix/configure.in:		    [Patch 996085], that introduces
	* unix/Makefile.in:		    --enable-man-suffix.

	* unix/installManPage:		    added
	* unix/mkLinks.tcl:		    removed
	* unix/mkLinks:			    removed
	* unix/configure:		    generated

	* unix/Makefile.in:		    Don't install tclConfig.h .

2004-11-17  Don Porter	<dgp@users.sourceforge.net>

	* unix/configure.in: The change below reveals that the public data
	type Tcl_StatBuf relies on config information. For now, disabled the
	use of the tclConfig.h file until its full impact on Tcl's interface
	can be assessed.

	* unix/configure:	autoconf-2.57

	* generic/tcl.h:	Moved the #include "tclConfig.h" out of
	* generic/tclInt.h:	tcl.h.	The config settings are not part of
	* generic/tclPort.:	the public interface, and having it there
	breaks compiled against uninstalled Tcl and extensions using
	autoconf-2.5*.

2004-11-16  Jeff Hobbs	<jeffh@ActiveState.com>

	* unix/tclUnixChan.c (TtySetOptionProc): fixed crash configuring
	-ttycontrol on a channel. [Bug 1067708]

2004-11-16  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclIOUtil.c (TclFSEpochOk): There were two code paths via
	which the thread copy of filesystemEpoch could be synched with the
	master copy, but only one kept the filesystem list cache up to date.
	Fix routes everything through a single code path. [Bug 1035775].

2004-11-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Stop architecture flags to 'ld' from
	getting lost when [load] is disabled. [Bug 1016796]

2004-11-16  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tcl.h:
	* unix/configure.in: changed HAVE_CONFIG_H to HAVE_TCL_CONFIG_H.

	* unix/configure: autoconf-2.57

2004-11-15  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclInt.h: Added comment warning that the old ERR_IN_PROGRESS
	and ERROR_CODE_SET flag values should not be re-used for the sake of
	those extensions that have accessed them.

	* generic/tclCmdMZ.c (Tcl_TraceObjCmd): Fixed Bug 1065378 which failed
	* tests/trace.test (trace-33.1):	to permit a variable trace
	created with [trace variable] to be destroyed with [trace remove].
	Thanks to Keith Vetter for the report.

2004-11-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/tclvars.n: Added section to documentation on global variables
	that are specific to tclsh and wish. [Patch 1065732]

2004-11-12  Jeff Hobbs	<jeffh@ActiveState.com>

	* generic/tclEncoding.c (TableFromUtfProc): correct crash condition
	when TCL_UTF_MAX == 6. [Bug 1004065]

2004-11-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/interp.n: Basic documentation of the TIP#221 API.

2004-11-12  Don Porter	<dgp@users.sourceforge.net>

	TIP #221 IMPLEMENTATION
	* generic/tclBasic.c:	Define [::tcl::Bgerror] in new interps.
	* generic/tclEvent.c:	Update Tcl_BackgroundError to make use of the
				registered [interp bgerror] command.
	* generic/tclInterp.c:	New [interp bgerror] subcommand.
	* tests/interp.test:	syntax tests updated.

	* generic/tclInt.h:	Moved verification of ptrdiff_t typedef from
	* generic/tclExecute.c: multiple .c files into one common header where
	* generic/tclVar.c:	it is verifiably after tclConfig.h inclusion.

2004-11-12  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tcl.h:
	* generic/tclInt.h:
	* unix/Makefile.in: include tclConfig.h from tcl.h and install it as a
	public header. Normalized compiler include path order to
	-I${BUILD_DIR} -I${UNIX_DIR} -I${GENERIC_DIR}.

	* unix/dltest/Makefile.in: add ${BUILD_DIR}/.. to include path to pick
	up tclConfig.h.

	* unix/tclUnixInit.c: moved check for HAVE_CFBUNDLE define after
	#include "tclInt.h" to ensure tclConfig.h has been included.

2004-11-12  Reinhard Max  <max@suse.de>

	* unix/config.h.in:
	* unix/tclConfig.h.in:	renamed

	* unix/Makefile.in:	Completed support for config header,
	* unix/configure.in:	fixed building outside of the unix dir,
	* unix/tclAppinit.c:	and reflected the name change of config.h.
	* generic/tclInt.h:

	* unix/configure:	generated

2004-11-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/config.h.in:	Allow configure to put all the C #defs into
	* unix/configure.in:	a file (called config.h) so that Unix builds
	* unix/tcl.m4:		now take far fewer lines of scrollback to
	* unix/Makefile.in:	proceed (making it less likely that any errors
	* generic/tclInt.h:	or warnings will get missed).
	* unix/tclAppInit.c:	Part of the TIP#34 upgrades.

	* unix/tcl.m4, unix/tclUnixPort.h: Check for pthread_attr_get_np in
	<pthread.h> before forcing the use of <pthread_np.h> to make things
	work on NetBSD 2.0. [Bug 1064882]

	* doc/binary.n, doc/upvar.n: More minor fixes.

2004-11-12  Daniel Steffen  <das@users.sourceforge.net>

	* doc/CrtChannel.3:
	* doc/Interp.3:
	* doc/Limit.3:
	* doc/binary.n:
	* doc/dict.n:
	* doc/tm.n:
	* doc/upvar.n: fixed *roff errors uncovered by running 'make html'.

	* tools/tcltk-man2html.tcl: added faked support for bullet point
	lists, i.e. *nroff ".IP \(bu" syntax.

2004-11-11  Daniel Steffen  <das@users.sourceforge.net>

	* tests/fCmd.test:
	* unix/tclUnixFCmd.c (TraverseUnixTree): added option to rewind() the
	readdir() loop whenever the source hierarchy has been modified by
	traverseProc (e.g. by deleting files); this is required to ensure
	complete traversal of the source hierarchy on certain filesystems like
	HFS+. Added test for failing recursive delete on Mac OS X that was due
	to this. [Bug 1034337]

	* generic/tclListObj.c (Tcl_ListObjReplace): use memmove() instead of
	manual copy loop to shift list elements. Decreases time spent in
	Tcl_ListObjReplace() from 5.2% to 1.7% of overall runtime of tclbench
	on a ppc 7455 (i.e. 200% speed increase). [Patch 1064243]

	* generic/tclHash.c: hoisted some constant pointer dereferences out of
	loops to eliminate redundant loads that the gcc optimizer didn't deal
	with. Decreases time spend in Tcl_FindHashEntry() by 10% over a full
	run of the tcl testuite on a ppc 7455. [Patch 1064243]

	* tests/fileName.test:
	* tests/fileSystem.test:
	* tests/io.test:
	* tests/msgcat.test:
	* tests/tcltest.test:
	* tests/unixInit.test: fixed bugs causing failures when running tests
	with -tmpdir arg not set to working dir.

	* macosx/Makefile: corrected path to html help inside framework.
	Prevent parallel make from building several targets at the same time.

	* macosx/tclMacOSXFCmd.c (struct fileinfobuf): force struct to be
	packed to prevent failures when builing with -malign=natural.

2004-11-10  Andreas Kupries <andreask@activestate.com>

	* unix/tclUnixChan.c: [Bug 727786]. Exterminated the code marked
	DEPRECATED. This code has not been used in over a year now, and we
	have no complaints.

2004-11-08  David Gravereaux <davygrvy@pobox.com>

	* win/tclWinPipe.c: The pipe channel driver now respects the -blocking
	option when closing is the same way the UNIX side works. This is to
	avoid a hung shell when exiting due to open pipes that refuse to close
	in a graceful manner.
	* doc/open.n: Added a note about -blocking 0 and lack of exit status
	as it had never been documented. [Bug 947693]

	***POTENTIAL INCOMPATIBILITY***

	Scripts that use async pipes on windows, must (like the UNIX side) set
	-blocking to 1 before calling [close] to receive the exit status.

2004-11-07  David Gravereaux <davygrvy@pobox.com>

	* tests/winFile.test: added contraint to winFile-4.0 to prevent it
	being run on NT4 [Bug 981829]

2004-11-05  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/reg.test: Major reorganization so that this file is much
	easier for a normal Tcl maintainer to comprehend. The test flags are
	still very cryptic, but they appear to have to be that way. The number
	of skipped tests has increased, but now the skipped tests have much
	more meaningful content.

	* tests/tm.test (genpaths): Add a [file normalize] so we pick up
	Windows drive letters, etc. [Bug 1053568]

2004-11-04  Don Porter	<dgp@users.sourceforge.net>

	* changes:	Updates toward an 8.5a2 release.

2004-11-03  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl (FreeScan): Fixed a bug where scanning "Monday"
	with a base time other than midnight incorrectly carried the base time
	forward.

	* test/clock.test (clock-33.{5,5a}): Made the test failure more
	informative.

	* tests/clock.test (clock-34.{28,44,45,46}): Removed 'knownBug'
	constraints from tests that no longer fail.

	Thanks to Don Porter for reporting these.

2004-11-03  David Gravereaux <davygrvy@pobox.com>

	* generic/tcl.h:		Moved the preprocessor logic
	* generic/tclDecls.h:		from tclInt.h of setting the
	* generic/tclInt.h:		TCL_STORAGE_CLASS macro to the
	* generic/tclIntDecls.h:	tcl*Decls.h files now that no
	* generic/tclIntPlatDecls.h:	use of EXTERN is left in tclInt.h.
	* generic/tclPlatDecls.h:	Proto for Tcl_Main moved in tcl.h
	* win/tclWinPort.h:		to prior the inclusion of the Stubs
	headers as they are now resetting TCL_STORAGE_CLASS. Removed
	extraineous reset from tclWinPort.h. [Patch 1055668]

	* generic/tclCompile.h: Removed extrainious reset of TCL_STORAGE_CLASS
	missed in my last edit.

2004-11-03  Don Porter	<dgp@users.sourceforge.net>

	* library/init.tcl ([unknown]): Corrections to the 2004-10-25 mods to
	Aunt ??? in [unknown]. Flaws revealed by Itcl test suite, which still
	apparently relies on this brokenness. Also added comment suggesting
	the error message that any code using this hack *ought* to receive in
	reply.

	* generic/tclTrace.c (TclCallVarTraces):  Improved ability to debug
	* tests/incr-old.test (incr-old-2.6):	  errors during variable
	* tests/incr.test (incr-{1,2}.28):	  traces by preserving the
	* tests/set.test (set-{2,4}.4):		  -errorinfo data.
	* tests/trace.test (trace-33.1):	  [Bug 527164]

2004-11-02  David Gravereaux <davygrvy@pobox.com>

	* generic/tclInt.h: added a check for #ifdef __cplusplus around the
	#define of MODULE_SCOPE. About the only time it would be problem is
	when someone is statically linking to Tcl and accessing internals from
	a C++ file and has name mangling issues from the lack of "C" after
	'extern' [Patch 1055668].
	* generic/tclCompile.h: Exchanged use of the EXTERN macro to the new
	MODULE_SCOPE macro. Lowered exported internals count by 35. [Patch
	1055668]
	* win/tclWinInt.h:
	* win/tclWinPort.h: exported internals dropped by a count of 14.
	* generic/tclFileSystem.h: Added use of MODULE_SCOPE on protos.
	* generic/tclRegexp.h: manipulating TCL_STORAGE_CLASS unnecessary.

2004-11-02  Don Porter	<dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:		Corrected some misleading
	* tests/tcltest.test (tcltest-26.1,2):	displays of ::errorInfo and
	::errorCode information when the -setup, -body, and/or -cleanup scripts
	return an unexpected return code. Thanks to Robert Seeger for the fix.
	[RFE 1017151].

2004-11-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclExecute.c (TclExecuteByteCode): Improved version of the
	NaN fix from Miguel Sofer. [Bug 761471]

2004-11-02  Kevin Kenny	 <kennykb@acm.org>

	* library/tzdata/America/Cuiaba: Change to DST rules for
	* library/tzdata/America/Havana: autumn of 2004.
	[ftp://elsie.nci.nih.gov/pub/tzdata2004g.tar.gz]

	* tools/tclZIC.tcl: Updated to be compatible with recent changes in
	library/clock.tcl.

2004-11-02  Vince Darley  <vincentdarley@users.sourceforge.net>

	* win/tclWinFile.c: Simplify TclpUtime to use Tcl_FSGetNativePath, and
	add comments.

2004-11-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInt.h: Change uses of EXTERN to MODULE_SCOPE (defined in
	this file too to be 'extern' if not overridden) as nothing declared in
	tclInt.h is supposed to be visible outside the Tcl core. If there *is*
	anything that extensions are actually using, we can open this up later
	on. [Patch 1055668]

	* doc/CrtChannel.3 (Tcl_GetChannelMode): Add synopsis. [Bug 1058446]

2004-11-01  Kevin B. Kenny  <kennykb@acm.org>

	* win/tclWinFile.c (FromCTime, TclpUtime): Replaced a call to the
	Posix 'utime' function with calls to Windows-API equivalents, to avoid
	a bug where the VC++ versions misconvert times across a Daylight
	Saving Time boundary. [Bug 926106]
	* win/tclWinInt.h (TclWinProcs):
	* win/tclWin32Dll.c (asciiProcs, unicodeProcs): Removed now-unused
	reference to 'utime'.
	* tests/cmdAH.test (cmdAH-24.12): Added test case for the above bug.

2004-11-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclExecute.c (TclExecuteByteCode): Make INST_EQ and friends
	handle NaN correctly in all cases. [Bug 761471]

	* generic/tclNamesp.c (NamespaceInscopeCmd): Make the error message
	generation the same as in NamespaceEvalCmd().
	(Tcl_Import): Rationalized to use Tcl_EvalObjv().

2004-10-31  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/io.test (io-40.3): Convert umask2 test constraint into a form
	that most people will be able to satisfy.

	* tests/cmdAH.test (cmdAH-8.45): Removed broken test constraint. It
	didn't do what it was intended to do, and it implied the other correct
	constraint. [Bug 1053908]

	* generic/tclCmdIL.c (InfoGlobalsCmd):
	* tests/info.test (info-8.4): Strip leading global-namespace
	specifiers from the pattern argument. [Bug 1057461]

2004-10-30  Kevin Kenny	 <kennykb@acm.org>

	* generic/clock.c: Replaced WIN32 macro with __WIN32__. [Bug 1054357].
	Thanks to David Gravereaux for the patch.
	* win/tclWinFile.c: Removed a long-standing bug that causes incorrect
	conversion between file time and UTC time if the file time is recorded
	in a different Daylight Saving Time status than the current one. [Bug
	926106]

2004-10-29  Don Porter	<dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:	Correct reaction to errors in the
	obsolete processCmdLineArgsHook.	[Bug 1055673]
	* library/tcltest/pkgIndex.tcl:	Bump to tcltest 2.2.7
	* unix/Makefile.in:
	* tests/all.tcl:	Update to use [tcltest::configure].

2004-10-29  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* library/tm.tcl (::tcl::tm::*): Use the core proc engine to generate
	the wrong-num-args error messages for the path ensemble.

	Ensembles can now (sometimes) rewrite the error messages of their
	subcommands so they appear more like the arguments that the user
	passed to the ensemble. Below is a description of changes involved in
	doing this.

	* tests/namespace.test (namespace-50.*): Tests of ensemble subcommand
	error message rewriting.
	* generic/tclProc.c (TclObjInterpProc): Make procedures implement
	their wrong-num-args message using Tcl_WrongNumArgs instead of
	something baked-at-home.
	* generic/tclNamesp.c (TclIsEnsemble, NsEnsembleImplementationCmd):
	Added test of ensemble-hood (available to rest of core) and made
	ensembles set up the rewriting for Tcl_WrongNumArgs to take advantage
	of.
	* generic/tclInt.h (Interp.ensembleRewrite): Extra fields.
	* generic/tclIndexObj.c (Tcl_WrongNumArgs): Add knowledge of what is
	going on in ensembles' command rewriting so this command can generate
	the right error message itself.
	* generic/tclBasic.c (Tcl_CreateInterp, TclEvalObjvInternal): Added
	code to initialize (as empty) the rewriting fields and reset them when
	we leak outside an ensemble implementation.

2004-10-28  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c (INST_START_CMD):
	* tests/execute.test (execute-8.3): fix for execution stack corruption
	[Bug 1055676]. Credit dgp for detective work and fix.

2004-10-27  Don Porter	<dgp@users.sourceforge.net>

	* tests/socket.test (socket-13.1):	Balanced [makeFile] and
	[removeFile] commands.

	* tests/clock.test:	Correct duplicate test names.
	* tests/namespace.test:
	* tests/string.test:
	* tests/io.test (io-50.4):	Use namespace variables.

2004-10-27  David Gravereaux <davygrvy@pobox.com>

	* generic/tclInt.decls:	  The following 9 functions were moved from
	* generic/tclInt.h:	  tclInt.h to the private/int Stubs table for
	* generic/tclIntDecls.h:  use by the test suite. As tclTest.obj is
	* generic/tclStubInit.c:  linked to the shell, these functions need
	"blessed" status so as to always be exported from the library. Being
	placed in the Stubs table guarantees this [Bug 1054748]:
		TclpObjRemoveDirectory,	TclpObjCopyDirectory,
		TclpObjCreateDirectory,	TclpObjDeleteFile,
		TclpObjCopyFile,	TclpObjRenameFile,
		TclpObjStat,		TclpObjAccess,
		TclpOpenFileChannel

	* tests/registry.test:	Fixed test files to load the correct
	* tests/winDde.test:	registry and dde packages by using the info
	* win/Makefile.in:	from makefiles to tell tcltest where to load
	* win/makefile.vc:	them from. This avoids grabbing the wrong
	package from $auto_path which might be the install point rather than
	the dev location. Kudos to Jennifer Hom for adding -load and
	-loadfile to the tcltest package. [Bug 926088]

	* win/tclWinThrd.c (TclFinalizeLock): release the critical section
	before deleting it. [Bug 731778]

	* generic/tcl.h: Removed the file level 'extern "C" {' and the
	coresponding closing block as it serves no purpose given that all the
	function prototypes have the proper extern usage already.

	* unix/tclAppInit.c:	When built as tcltest, TclThread_Init was
	* win/tclAppInit.c:	getting called twice. First by Tcltest_Init,
	then again in Tcl_AppInit. The call from Tcl_AppInit is now removed.

2004-10-27  Andreas Kupries <andreask@activestate.com>

	* tests/tm.test:  Expanded on the testsuite entered by Donal.
	* library/tm.tcl: Even found bugs, these have been corrected.

2004-10-26  Kevin Kenny <kennykb@acm.org>

	* tests/format.test (format-19.1): Additional regression test for [Bug
	868489].

2004-10-27  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/*.n: Many small general documentation fixes.

2004-10-26  David Gravereaux <davygrvy@pobox.com>

	* generic/tclPipe.c (TclCleanupChildren): bad cast of resolvedPid
	caused PIDs on win95 to go negative. winpipe-4.2 brought this to the
	surface. Fixed with sprintf in place of TclFormatInt. Thanks to hgiese
	[Patch 767676]

2004-10-26  Andreas Kupries <andreask@activestate.com>

	* library/tm.tcl (::tcl::tm::Defaults): Added a second [file dirname]
	around the location of the executable. This fixes [Bug 1038705].
	Instable of a bogus "foo/bin/lib" we now have the correct "foo/lib" as
	a base path for modules.

2004-10-26  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclParse.c (Tcl_SubstObj):	Fix for failed subst-12.3 test
	* tests/subst.test (subst-12.3-5):	More tests for Bug 1036649.

	* unix/Makefile.in (install-libraries): Updated the installation of
	the http, msgcat, and tcltest packages to install as Tcl Modules on
	Unix systems. Other platform Makefiles still need updating. [Patch
	1054370]

	* tests/basic.test:	Added missing constraints.
	* tests/compile.test:
	* tests/fileSystem.test:

	* tests/init.test (init-2.8):	Updated to not rely on http package.

2004-10-26  Miguel Sofer <msofer@users.sf.net>

	* generic/tclInt.h:
	* generic/tclVar.c: removed more direct references to the VAR flags,
	replaced with access macros.

2004-10-26  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/expr.n: Clarified that non-num/non-bool literals require
	quoting. [Bug 1027849]. Also listed booleans as acceptable values.

2004-10-26  Kevin B. Kenny <kennykb@acm.org>

	* library/clock.tcl (FreeScan): Fixed a bug that caused relative days
	of the week in free-form [clock scan] to be evaluated in the wrong
	time zone.
	* tests/clock.test (clock-31.[456]): Made sure that there isn't an
	env(TZ) or env(TCL_TZ) lying around that will override the time zone
	that we're trying to establish with the simulated registry.
	Both problems reported as [Bug 1054101].

2004-10-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/string.n (map): Rewrote to clarify that we don't just map single
	characters. [Bug 1048005]
	* doc/info.n (procs): Clarified that the pattern argument may have
	namespace separators in it. [Bug 1047928]

	* tests/cmdAH.test (cmdAH-8.45): Simplify in the hope that the reasons
	for [Bug 1053908] will become clearer.

2004-10-25  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c (IllegalExprOperandType,TclExecuteByteCode):
	Removed several DECACHE_INFO/CACHE_INFO pairs that are no longer
	needed for protection because routines like Tcl_SetErrorCode() and
	Tcl_AddErrorInfo() can no longer re-enter bytecode execution.

	* generic/tclResult.c (TclProcessReturn): Bug fix. Be sure that a
	missing -errorinfo option when code == TCL_ERROR causes the errorInfo
	field to get reset.

	* tests/thread.test (thread-4.4): Test depended on a ::errorInfo value
	initialized to "". Added code to test to setup that requirement.

	* library/auto.tcl:	Purged Tcl's script library of all
	* library/clock.tcl:	remaining references to global vars
	* library/init.tcl:	::errorInfo and ::errorCode.

	* generic/tclMain.c (Tcl_Main): Updated to make use of
	TclGetReturnOptions instead of ::errorInfo variable.

	* generic/tclInterp.c (tclInit): Bug fix. Access dict variables with
	[dict get], not array syntax.

2004-10-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/tm.test: Rewrote the tests to actually perform syntax checks
	on the public API. Added a new test (currently failing) to indicate
	that the test suite is not complete yet.
	* library/tm.tcl (path): Rewrote to turn this command into an ensemble
	to make it faster and simpler.

2004-10-24  Miguel Sofer <msofer@users.sf.net>

	* generic/tclCmdIL.c:
	* generic/tclExecute.c:
	* generic/tclInt.h:
	* generic/tclTrace.c: defined new macros to get/set the flags of
	variables. The only files that still access the flag values directly
	are tclCompCmds.c, tclCompile.c, tclProc.c and tclVar.c

2004-10-24  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_LogCommandInfo,Tcl_AddObjErrorInfo): Shift
	the initialization of errorCode to NONE to more central location.

	* generic/tclEvent.c (BgError,Tcl_BackgroundError,HandleBgErrors):
	Rewrite to build on the new TclGet/SetReturnOptions routines.

	* generic/tclResult.c (TclGetReturnOptions): Add call to
	Tcl_AddObjErrorInfo to be sure error fields are initialized.

	* generic/tclResult.c (TclTransferResult): Rewrite to build on the new
	TclGet/SetReturnOptions routines.

2004-10-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/tm.n: Tightened up the documentation.
	* tests/tm.test: Created (with partially dummy content) so TIP#189 can
	be marked Final.

	* generic/tclNamesp.c (NsEnsembleImplementationCmd): Make ensembles
	cut their implementations out of error traces. This is the right thing
	to do more often than not.

2004-10-22  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl: Fixed a typo where the fallback time zone became
	::localtime instead of :localtime. Fixed a bug where time zone names
	containing hyphens could not be loaded.
	* tests/clock.test: Added regression test cases that covers both bugs.
	Thanks to Todd M. Helfter <tmh@jumpgate.itsp.purdue.edu> for finding
	these bugs.

2004-10-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclExecute.c (TclCompEvalObj, Tcl_ExprObj):
	* generic/tclProc.c (TclProcCompileProc): Always call object
	freeIntRepProc's in the same way.

2004-10-22  Miguel Sofer <msofer@users.sf.net>

	* generic/tclVar.c: fixed bug in commit of 2004-07-23, which was
	causing a leak of Proc structures and failure of compile-12.1. Two
	lines were 'zombies' from the previous way localVarNames worked.
	Credit dgp for finding this.

2004-10-21  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclInt.h (Interp):
	* generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp):
	* generic/tclResult.c (GetKeys,ReleaseKeys,etc.): Moved the key values
	of the return options dictionary out of private fields of the Interp
	struct and into thread-static values managed in tclResult.c.

	* generic/tclCmdAH.c (Tcl_CatchObjCmd, Tcl_ErrorObjCmd): Updated to
	call the new TclGet/SetReturnOptions routines to do much of their
	work.

	* generic/tclInt.h (TclGetReturnOptions,TclSetReturnOptions):
	* generic/tclResult.c (TclGetReturnOptions,TclSetReturnOptions): New
	utility routines to get/set the return options of an interp. Intent is
	that these routines will be converted to public routines after TIP
	approval.

	* generic/tclCmdMZ.c (TclProcessReturn,TclMergeReturnOptions):
	* generic/tclResult.c (TclProcessReturn,TclMergeReturnOptions): Move
	internal utility routines from tclCmdMZ.c to tclResult.c.

	* generic/tclBasic.c (Tcl_CreateInterp, Tcl_DeleteInterp):
	* generic/tclResult.c (TclTransferResult): Rework so that
	iPtr->returnOpts can be NULL when there are no special options.

	* generic/tclResult.c (TclRestoreInterpState): Plug potential memory
	leak.

2004-10-21  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclBasic.c: Various changes to [clock format] that,
	* generic/tclClock.c: together, make it roughly twice as fast
	* generic/tclInt.h:   while all tests in the test suite
	* library/clock.tcl:  continue to pass.

2004-10-20  Andreas Kupries <andreask@activestate.com>

	* win/Makefile.in (install-msgs):   Fixed a problem with the
	* win/Makefile.in (install-tzdata): installation of timezone data and
	message catalogs. They used the installed tcl library directory, not
	the source library. Before it was installed. Switched to source lib
	dir. Thanks to Kevin for the help in figuring this out.

2004-10-20  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclThreadTest.c (ThreadEventProc): Corrected subtle bug
	where the returned (char *) from Tcl_GetStringResult(interp) continued
	to be used without copying or refcounting, while activity on the
	interp continued. That's not safe, and recent changes demonstrated the
	lack of safety with failing tests thread-4.3 and thread-4.5.

2004-10-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclDictObj.c (DictWithCmd): Make sure all paths (that are
	not themselves error paths) do not lose the result code.

2004-10-19  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclInt.h (Tcl*InterpState):		New internal routines
	* generic/tclResult.c (Tcl*InterpState):	TclSaveInterpState,
	TclRestoreInterpState, and TclDiscardInterpState are superior
	replacements for Tcl_(Save|Restore|Discard)Result. Intent is that
	these routines will be converted to public routines after TIP
	approval. Interfaces for these routines were shamelessly stolen from
	Itcl.

	* generic/tclBasic.c (TclEvalObjvInternal):
	* generic/tclDictObj.c (DictUpdateCmd, DictWithCmd):
	* generic/tclIOGT.c (ExecuteCallback):
	* generic/tclTrace.c (Trace*Proc,TclCheck*Traces,TclCallVarTraces):
	Callers of Tcl_*Result updated to call the new routines. The calls
	were relocated in several cases to perform save/restore operations
	only when needed.

	* generic/tclEvent.c (HandleBgErrors):
	* generic/tclFCmd.c (CopyRenameOneFile): Calls to Tcl_*Result that
	were eliminated because they appeared to serve no useful purpose,
	typically saving/restoring an error message, only to throw it away.

2004-10-18  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp):
	* generic/tclCmdAH.c (Tcl_CatchObjCmd):
	* generic/tclCmdMZ.c (TclMergeReturnOptions,TclProcessReturn):
	* generic/tclCompCmds.c (TclCompileReturnCmd):
	* generic/tclExecute.c (TclCompEvalObj):
	* generic/tclInt.h (Interp):
	* generic/tclProc.c (TclUpdateReturnInfo): Place primary storage of
	the -level and -code information in private fields of the Interp
	struct, rather than in a DictObj. This should significantly improve
	performance of TclUpdateReturnInfo.

2004-10-17  Miguel Sofer <msofer@users.sf.net>

	* generic/tclResult.c: removed unused variable [Bug 1048588]. Thanks
	to Daniel South.

2004-10-15  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c (TclProcessReturn):	Now that primary
	* generic/tclProc.c (TclUpdateReturnInfo):	storage for the
	errorInfo and errorCode values are internal fields, we can set them at
	the time of the [return] command, and not have to wait until the
	specified number of "-level"s have popped.

	(TclTeardownNamespace):
	* generic/tclProc.c (TclUpdateReturnInfo):
	* generic/tclResult.c (Tcl_ResetResult, TclTransferResult):
	* generic/tclTrace.c (CallVarTraces):
	Reworked management of the "errorInfo" data of an interp. That
	information is now primarily stored in a new private (Tcl_Obj *) field
	of the Interp struct, rather than using a global variable ::errorInfo
	as the primary storage. The ERR_IN_PROGRESS flag bit value is no
	longer required to manage the value in its new location, and is
	removed. Variable traces are established to support compatibility for
	any code expecting the ::errorInfo variable to hold the information.

	***POTENTIAL INCOMPATIBILITY***
	Code that sets traces on the ::errorInfo variable may notice a
	difference in timing of the firing of those traces. Code that uses the
	value ERR_IN_PROGRESS.

2004-10-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	TIP#217 IMPLEMENTATION

	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Add -indices option from James
	Salsman. [Patch 1017532]

	* generic/tclUtil.c (TclMatchIsTrivial): Detect degenerate cases of
	glob matching that let us avoid scanning through hash tables.
	* generic/tclCmdIL.c (InfoCommandsCmd, InfoGlobalsCmd, InfoProcsCmd):
	(InfoVarsCmd): Use this to speed up some [info] subcommands.

2004-10-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	TIP#201 AND TIP#212 IMPLEMENTATIONS

	* doc/dict.n, doc/expr.n: Documentation for new functionality.
	* tests/expr.test: Basic tests of 'in' and 'ni' behaviour.
	* tests/dict.test (dict-21.*,dict-22.*): Tests for [dict update] and
	[dict with].
	* generic/tclExecute.c (TclExecuteByteCode): Implementation of the
	INST_LIST_IN and INST_LIST_NOT_IN bytecodes.
	* generic/tclParseExpr.c (GetLexeme): Parse the 'in' and 'ni'
	operators for TIP#201.
	* generic/tclDictObj.c (DictUpdateCmd,DictWithCmd): Core of
	implementation of TIP#212; docs and tests still to do...

2004-10-07  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclTest.c (TestsetobjerrorcodeCmd):  Simplified.

2004-10-07  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c:
	* generic/tclFileSystem.h:

	* generic/tclPathObj.c:
	* unix/tclUnixFile.c:
	* win/tclWinFile.c:
	* tests/fileName.test:
	* tests/winFCmd.test: code reorganization for better generic/platform
	code splitting [Bug 925620] removing the need for several #ifdef's,
	and tests and fix for an unreported Windows glob problem ('glob -dir
	C: -tails *').

2004-10-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* *.3: Convert CONST to const and VOID to void so we document how
	people should actually use the Tcl API and not the compatibility hacks
	that it has to have.

	* doc/man.macros, *.3: Update .AS macro so it can know how wide to
	make the third column of the argument list. Update documentation for C
	API (only users) to take advantage of this.

	* doc/FileSystem.3: Formatting fixes for greater documentation
	clarity.

2004-10-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclFileName.c (DoGlob, TclGlob): Stop messy sharing of
	interpreter result and instead use a private object for collecting the
	result of the glob. This simplifies TclGlob quite a lot.
	* generic/tclIOUtil.c (Tcl_FSMatchInDirectory): Simplify by removing
	some nesting. Also standardize variable names.
	(FsAddMountsToGlobResult): Force updates to the list to be done
	in-place, putting a side-condition of non-shared-ness on the resultPtr
	argument to Tcl_FSMatchInDirectory, but everything would have broken
	before if that was shared *anyway*.

	* generic/tclEncoding.c (LoadTableEncoding): Removed reference to Tcl
	interpreter; it wasn't needed as direct object use is more efficient.

	* generic/tclPathObj.c: Made this file follow the style rules in the
	Engineering Manual more closely, and also take advantage of the
	internal object manipulation macros more.

	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Reorganized to have fewer
	magic flag variables and to separate the code that scans for a match
	from the code that processes a match body.

	that circumstance a Tcl_Panic() will be the result. Searched for
	example of this practice and replaced with safer alternatives, often
	using the Tcl_AppendResult() routine that dkf just rehabilitated.
	* library/dde/pkgIndex.tcl: Bump to dde 1.3.1
	* library/reg/pkgIndex.tcl: Bump to registry 1.1.5

2004-10-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/SetResult.3: Made Tcl_AppendResult non-deprecated; better that
	people use it than most of the common alternatives!
	* generic/tclResult.c (Tcl_AppendResultVA): Make this work better with
	Tcl_Objs. [Patch 1041072]
	(Tcl_SetResult, Tcl_AppendElement): Change string to stringPtr to
	avoid C++ keywords.

2004-10-05  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c (TclObjInvoke): More simplification of the
	TclObjInvoke routine toward unification with the rest of the
	evaluation stack.

	* generic/tclBasic.c (Tcl_CreateInterp, Tcl_DeleteInterp)
	(TclEvalObjvInternal, Tcl_LogCommandInfo):

	(TclTeardownNamespace):
	* generic/tclResult.c (Tcl_ResetResult, Tcl_SetObjErrorCode)

	* generic/tclTrace.c (CallVarTraces):
	Reworked management of the "errorCode" data of an interp. That
	information is now primarily stored in a new private (Tcl_Obj *) field
	of the Interp struct, rather than using a global variable ::errorCode
	as the primary storage. The ERROR_CODE_SET flag bit value is no longer
	required to manage the value in its new location, and is removed.
	Variable traces are established to support compatibility for any code
	expecting the ::errorCode variable to hold the information.

	***POTENTIAL INCOMPATIBILITY***
	Code that sets traces on the ::errorCode variable may notice a
	difference in timing of the firing of those traces.

	* generic/tclNamesp.c (Tcl_PopCallFrame): Removed Bug 1038021
	workaround. That bug is now fixed.

2004-10-04  Kevin B. Kenny  <kennykb@acm.org>

	* tests/clock.test (clock-34.*): Removed an antibug that forced
	comparison of [clock scan] results with the :localtime time zone. Now
	that [clock scan] uses the current time zone instead, the antibug
	caused several tests to fail. [Bug 1038554]

2004-10-04  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclParseExpr.c (GetLexeme): Ensure that the 'eq' and 'ne'
	operators are followed by non-alphabetic characters so lexemes can't
	run together. [Bug 884830]

	* doc/DictObj.3, doc/dict.n: Clarified that a dictionary is not
	order-preserving. [Bug 1032243] Also added another example to show off
	more ways of using a dictionary and a few other formatting
	improvements.

2004-10-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclDictObj.c (TraceDictPath, Tcl_DictObjPutKeyList): Add
	support for automatic creation of dictionary paths since that is what
	everyone seems to actually expect of the API! [Bug 1037235]
	(Tcl_DictObjNext): Make calling this after Tcl_DictObjDone non-fatal
	as that simplifies a number of internal APIs. This doesn't break any
	existing working code as it is a case which previously caused a panic.

2004-10-02  Don Porter	<dgp@users.sourceforge.net>

	* tests/namespace.test (namespace-8.7):	Another test for save/restore
	of ::errorInfo and ::errorCode during global namespace teardown.

2004-10-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclProc.c (TclObjGetFrame, Tcl_UplevelObjCmd):

	references in the level object for speed.

2004-09-30  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_CreateInterp):
	* generic/tclInt.h (Interp): Removed the flag bit value
	EXPR_INITIALIZED. It was set during interp creation and never tested.
	Whatever purpose it had is in the past.

	* generic/tclBasic.c (Tcl_EvalObjEx):	Removed the flag bit value
	* generic/tclInt.h (Interp):	        USE_EVAL_DIRECT. It was used
	* generic/tcLTest.c (TestevalexObjCmd): only in the testing command
	* tests/parser.test (parse-9.2):        [testevalex] and nothing in
	the test suite made use of the capability it enabled.

	* generic/tclBasic.c (Tcl_AddObjErrorInfo): More re-organization
	* generic/tclCmdAH.c (Tcl_ErrorObjCmd):	    of the management of
	* generic/tclCmdMZ.c (TclProcessReturn):    the errorCode value.
	* tests/error.test (error-6.4-9):

	* generic/tclNamespace.c (TclTeardownNamespace): Tcl_Obj-ified
	* tests/namespace.test (namespace-8.5,6):	 the save/restore of
	::errorInfo and ::errorCode during global namespace teardown. Revised
	the comment to clarify why this is done, and added tests that will
	fail if this is not done.

	* generic/tclResult.c (TclTransferResult): Added safety checks so that
	unexpected undefined ::errorInfo or ::errorCode will not lead to a
	segfault.

	* generic/tclTrace.c (TclCallVarTraces):  Save/restore the flag values
	* tests/var.test (var-16.1):	          that define part of
