 2007-05-10  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclInt.h:     TclFinalizeThreadAlloc() is always defined,

 	so make sure it is also always declared.

 	[Tcl Bug 1706140]

 	* generic/tclCmdMZ.c (Trace*Proc):	Update Tcl_VarTraceProcs so

 	* generic/tclLink.c (LinkTraceProc):    that they call

 	* generic/tclUtil.c (TclPrecTraceProc): Tcl_InterpDeleted() for

 	themselves, and do not rely on (frequently buggy) setting of the

 	TCL_INTERP_DESTROYED flag by the trace core.

 	* generic/tclVar.c:     Update callers of CallVarTraces to not

 	pass in the TCL_INTERP_DESTROYED flag.  Also apply filters so that

 	public routines only pass documented flag values down to lower level

 	routines.

 	* generic/tclVar.c (CallVarTraces):        The setting of the

 	TCL_INTERP_DESTROYED flag is now done entirely within the

 	CallVarTraces routine, the only place it can be done right.

 2007-04-30  Daniel Steffen  <das@users.sourceforge.net>

 	* unix/Makefile.in: add 'tclsh' dependency to install targets that rely

 	on tclsh, fixes parallel 'make install' from empty build dir.

 2007-04-29  Daniel Steffen  <das@users.sourceforge.net>

 	* unix/tclUnixPort.h:        for TclpLocaltime and TclpGmtime.

 	* unix/tclUnixTime.c:        CONST TclpTime_t is a 'time_t *CONST'

 	* win/tclWinTime.c:          and not a 'CONST time_t*' [Bug 1677275]

 	* generic/tclIntDecls.h:     

 	* generic/tclIntPlatDecls.h: Regenerated.

 2007-03-24  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

 	* win/tclWinThrd.c: Thread exit handler marks the current 

 	thread as un-initialized. This allows exit handlers that

 	are registered later to re-initialize this subsystem in 

 	case they need to use some sync primitives (cond variables)

 	from this file again. 

 2007-03-19  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclEvent.c (Tcl_CreateThread):	Replaced some calls to

 	* generic/tclPkg.c (CheckVersion):	Tcl_Alloc() with calls to

 	* unix/tclUnixTime.c (SetTZIfNecessary):	ckalloc(), which better

 	* win/tclAppInit.c (setargv):	supports memory debugging.

 2007-03-17  Kevin Kenny  <kennykb@acm.org>

 	* win/tclWinReg.c (GetKeyNames): Size the buffer for enumerating

 	of the loop as defense against shimmers.  [Bug 1671087]

 	* generic/tclVar.c (TclArraySet):	Re-fetch pointers for the list

 	* tests/var.test (var-17.1):	argument of [array set] each time

 	  supplied by Mo DeJong to fix [Bug 1516109]. Backport from Tcl

 	  8.5. Mo's description: Clear the TCL_ENCODING_END flag when end

 	  bytes are written. This fix keep this method from writing escape

 	  bytes for an encoding like iso2022-jp multiple times when the

 	  escape byte overlap with the end of the IO buffer.

 	* tests/io.test: Add test case for escape byte overlap case.

 	* unix/tcl.m4:       integrate CPPFLAGS into CFLAGS as late as possible

 	* unix/configure.in: and move (rather than duplicate) -isysroot flags

 	from CFLAGS to CPPFLAGS to avoid errors about multiple -isysroot flags

 	from some older gcc builds.

 	* unix/configure: autoconf-2.13

 2007-01-22  Andreas Kupries <andreask@activestate.com>

 	* compat/memcmp.c (memcmp): Fixed the VOID / CONST typo introduced

 	  by the last checkin.

 2007-01-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* macosx/tclMacOSXNotify.c: accommodate changes to prototypes of

 	OSSpinLock(Un)Lock API.

 2006-12-05  Andreas Kupries <andreask@activestate.com>

 	* tests/pkg.test:   Backport to 8.4 (Don Porter's work):

 	* generic/tclPkg.c: When no requirements are supplied to a [package

 	require $pkg] and [package unknown] is invoked to find a satisfying

 	package, pass the requirement argument "0-" (which means all versions

 	are acceptable). This permits a registered [package unknown] command

 	to call [package vsatisfies $testVersion {*}$args] without any special

 	handling of the empty $args case. This fixes/avoids a bug in

 	[::tcl::tm::UnknownHandler] that was causing old TM versions to be

 	provided in preference to newer TM versions. Thanks to Julian Noble

 	for discovering the issue.

 	* generic/tclFileName.c (TclDoGlob): match incr with existing decr.

 	* unix/Makefile.in: add valgrindshell target and update default

 	VALGRINDARGS. User can override, or add to it with VALGRIND_OPTS env

 	var.

 	* generic/tclBasic.c (Tcl_CreateInterp): init iPtr->threadId

 	* generic/tclIOGT.c (ExecuteCallback): 

 	* generic/tclPkg.c (Tcl_PkgRequireEx): replace Tcl_GlobalEval(Obj)

 	with more efficient Tcl_Eval(Obj)Ex

 2006-08-22  Andreas Kupries <andreask@activestate.com>

 	* unix/tclUnixNotfy.c (Tcl_WaitForEvent): Fixed broken if syntax

 	committed 2006-08-21 by Daniel. The broken syntax is visible to all

 	unix platforms, but not on OSX for machines which HAVE_COREFOUNDATION.

 2006-08-21  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclIOUtil.c:	Revisions to complete the thread finalization

 	of the cwdPathPtr. [Bug 1536142]

 2006-08-21  Daniel Steffen  <das@users.sourceforge.net>

 	* macosx/tclMacOSXNotify.c (Tcl_WaitForEvent): if the run loop is

 	already running (e.g. if Tcl_WaitForEvent was called recursively),

 	re-run it in a custom run loop mode containing only the source for the

 	notifier thread, otherwise wakeups from other sources added to the

 	common run loop modes might get lost; sync panic msg changes from

 	HEAD.

 	* unix/tclUnixNotfy.c (Tcl_WaitForEvent): on 64-bit Darwin,

 	pthread_cond_timedwait() appears to have a bug that causes it to wait

 	forever when passed an absolute time which has already been exceeded

 	by the system time; as a workaround, when given a very brief timeout,

 	just do a poll on that platform. [Bug 1457797]

 	* unix/tclUnixPort.h (Darwin): override potentially faulty configure

 	detection of termios availability in all cases, since termios is known

 	to be present on all Mac OS X releases since 10.0. [Bug 497147]

 2006-08-18  Daniel Steffen  <das@users.sourceforge.net>

 	* unix/tcl.m4 (Darwin): add support for --enable-64bit on x86_64, for

 	universal builds including x86_64, for 64-bit CoreFoundation on

 	Leopard and for use of -mmacosx-version-min instead of

 	MACOSX_DEPLOYMENT_TARGET.

 	* unix/configure: autoconf-2.13

 	* generic/tcl.h:      add fixes for building on Leopard and support

 	* unix/tclUnixPort.h: for 64-bit CoreFoundation on Leopard.

 	* unix/tclUnixPort.h: on Darwin x86_64, disable use of vfork as it

 	causes execve to fail intermittently. (rdar://4685553)

 	* macosx/README: updates for x86_64 support and Xcode 2.4.

 	* unix/tclUnixChan.c (TclUnixWaitForFile): with timeout < 0, if

 	select() returns early (e.g. due to a signal), call it again instead

 	of returning a timeout result. Fixes intermittent event-13.8 failures.

 2006-08-09  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclEncoding.c:	Replace buffer copy in for loop with

 	call to memcpy(). Thanks to afredd. [Patch 1530262]

 2006-08-03  Daniel Steffen  <das@users.sourceforge.net>

 	* unix/tclUnixPipe.c (TclpCreateProcess): for USE_VFORK: ensure

 	standard channels are initialized before vfork() so that the child

 	doesn't potentially corrupt global state in the parent's address

 	space.

 2006-07-30  Kevin Kenny  <kennykb@acm.org>

 	* tests/clock.test: Allowed UTC as a synonym for GMT in two tests that

 	indirectly invoke 'strftime' with the result of 'gmtime' to fix a

 	bogus test failure on FreeBSD systems. [Bug 1513489]

 2006-07-30  Joe English  <jenglish@users.sourceforge.net>

 	* doc/AppInit.3: Fix typo [Bug 1496886]

 2006-07-20  Daniel Steffen  <das@users.sourceforge.net>

 	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier, Tcl_WaitForEvent):

 	create notifier thread lazily upon first call to Tcl_WaitForEvent()

 	rather than in Tcl_InitNotifier(). Allows calling exeve() in processes

 	where the event loop has not yet been run (Darwin's execve() fails in

 	processes with more than one thread), in particular allows embedders

 	to call fork() followed by execve(), previously the pthread_atfork()

 	child handler's call to Tcl_InitNotifier() would immediately recreate

 	the notifier thread in the child after a fork.

 	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier):	   add support for

 	* unix/tclUnixFCmd.c (DoRenameFile, CopyFileAtts): weakly importing

 	* unix/tclUnixInit.c (TclpSetInitialEncodings):	   symbols not

 	available on OSX 10.2 or 10.3, enables binaires built on later OSX

 	versions to run on earlier ones.

 	* macosx/README: document how to enable weak-linking; cleanup.

 	* unix/tclUnixPort.h: add support for weak-linking; conditionalize

 	AvailabilityMacros.h inclusion; only disable realpath on 10.2 or

 	earlier when threads are enabled.

 	* unix/tclLoadDyld.c (TclpLoadMemoryGetBuffer): change runtime Darwin

 	* unix/tclUnixInit.c (TclpInitPlatform):	release check to use

 						       global initialized once

 	* unix/tclUnixFCmd.c (DoRenameFile, TclpObjNormalizePath): add runtime

 	Darwin release check to determine if realpath is threadsafe.

 	* unix/configure.in: add check on Darwin for compiler support of weak

 	* unix/tcl.m4:	     import and for AvailabilityMacros.h header; move

 	Darwin specific checks & defines that are only relevant to the tcl

 	build out of tcl.m4; restrict framework option to Darwin; cleanup

 	quoting.

 	* unix/configure: autoconf-2.13

 	* unix/tclLoadDyld.c (TclpLoadMemory):

 	* unix/tclUnixPipe.c (TclpCreateProcess): fix signed-with-unsigned

 	comparison and other warnings from gcc4 -Wextra.

 2006-07-13  Andreas Kupries <andreask@activestate.com>

 	* unix/tclUnixPort.h: Added the inclusion of <AvailabilityMacros.h>.

 	The missing header caused the upcoming #if conditions to wrongly

 	exclude realpath, causing file normalize to ignore symbolic links in

 	the path.

 2006-07-11  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

 	* generic/tclAsync.c: Made Tcl_AsyncDelete() more tolerant when called

 	after all thread TSD has been garbage-collected.

 2006-07-10  Jeff Hobbs  <jeffh@ActiveState.com>

 	* generic/tclIO.c (Tcl_CreateChannel): allow Tcl std channel

 	inheritance to be #defined out (default remains in).

 2006-06-15  Don Porter  <dgp@users.sourceforge.net>

 	* changes:		changes to start prep for an 8.4.14 release.

 2006-06-14  Daniel Steffen  <das@users.sourceforge.net>

 	* unix/tclUnixPort.h (Darwin): support for MAC_OS_X_VERSION_MAX_ALLOWED

 	define from AvailabilityMacros.h: override configure detection and only

 	use API available in the indicated OS version or earlier.

 2006-06-14  Pat Thoyts  <patthoyts@users.sourceforge.net>

 	* generic/regerror.c:	Enable building Tcl with Microsoft's latest

 	* generic/tcl.h:	compiler offering (VS2005). We have to handle

 	* generic/tclDate.c:	a number of oddities as they have deprecated

 	* tests/env.test:	most of the standard C library and now

 	* win/makefile.vc:	generate manifest files to be linked into the

 	* win/nmakehlp.c:	binaries. [Bug 1424909]

 	* win/rules.vc:		

 	* win/tclWinTime.c:

 2006-06-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* unix/tclLoadDl.c (TclpDlopen): Workaround for a compiler bug in Sun

 	Forte 6. [Bug 1503729]

 2006-06-06  Don Porter  <dgp@users.sourceforge.net>

 	* doc/GetStdChan.3:	Added recommendation that each call to

 	Tcl_SetStdChannel() be accompanied by a call to Tcl_RegisterChannel().

 2006-05-31  Jeff Hobbs  <jeffh@ActiveState.com>

 	* generic/tclNamesp.c (NamespaceInscopeCmd): revert [Bug 1400572]

 	fix of 2006-01-09 for [namespace inscope] as it seems to mess with

 	itcl scope decoding. Leaving namespace-29.6 test failure until final

 	cause it determined.

 2006-05-29  Jeff Hobbs  <jeffh@ActiveState.com>

 	* generic/tcl.h (Tcl_DecrRefCount): use if/else construct to allow

 	placement in unbraced outer if/else conditions. (jcw)

 2006-05-27  Daniel Steffen  <das@users.sourceforge.net>

 	* macosx/tclMacOSXNotify.c: implemented pthread_atfork() handler that

 	* unix/tcl.m4 (Darwin):	    recreates CoreFoundation state and notifier

 	thread in the child after a fork(). Note that pthread_atfork() is

 	available starting with Tiger only. Because vfork() is used by the core

 	on Darwin, [exec]/[open] are not affected by this fix, only extensions

 	or embedders that call fork() directly (such as TclX). However, this

 	only makes fork() safe from corefoundation tcl with --disable-threads;

 	as on all platforms, forked children may deadlock in threaded tcl due

 	to the potential for stale locked mutexes in the child. [Patch 923072]

 	* unix/configure: autoconf-2.59

 2006-05-24  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

 	* unix/tcl.m4 (SC_CONFIG_SYSTEM): Fixed quoting of command script to

 	awk; it was a rarely used branch, but it was wrong. [Bug 1494160]

 2006-05-13  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclFileName.c (TclDoGlob):	Disabled the partial

 	normalization done by the recursive glob routine, since changing the

 	precise string of the pathname broke [glob] on some Tcl_Filesystems.

 	[Bug 943995]

 	* generic/tclProc.c (ProcCompileProc):	When a bump of the compile

 	epoch forces the re-compile of a proc body, take care not to

 	overwrite any Proc struct that may be referred to on the active

 	call stack. This fixes [Bug 1482718]. Note that the fix will not be

 	effective for code that calls the private routine TclProcCompileProc()

 	directly.

 2006-05-05  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclMain.c (Tcl_Main):		Corrected flaw that required

 	* tests/main.test: (Tcl_Main-4.5):	processing of one interactive

 	command before passing control to the loop routine registered with

 	Tcl_SetMainLoop() [Bug 1481986]

 2006-05-04  Don Porter  <dgp@users.sourceforge.net>

 	* README:		Bump version number to 8.4.14

 	* generic/tcl.h:

 	* tools/tcl.wse.in:

 	* unix/configure.in:

 	* unix/tcl.spec:

 	* win/README.binary:

 	* win/configure.in:

 2006-04-12  Don Porter  <dgp@users.sourceforge.net>

 	*** 8.4.13 TAGGED FOR RELEASE ***

 	* changes:	updates for another RC.

 2006-04-11  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclCmdMZ.c:	Stop some interference between enter traces

 	* tests/trace.test:	and enterstep traces. [Bug 1458266]

 2006-04-10  Don Porter  <dgp@users.sourceforge.net>

 	* changes:	updates for another RC.

 2006-04-06  Jeff Hobbs  <jeffh@ActiveState.com>

 	* generic/tclRegexp.c (FinalizeRegexp): full reset data to indicate

 	readiness for reinitialization.

 2006-04-06  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct):	It seems there

 	* tests/indexObj.test:	are extensions that rely on the prior behavior

 	* doc/GetIndex.3:	that the empty string cannot succeed as a

 	unique prefix matcher, so I'm restoring Donal Fellows's solution.

 	Added mention of this detail to the documentation. [Bug 1464039]

 2006-04-06  Daniel Steffen  <das@users.sourceforge.net>

 	* unix/tcl.m4: removed TCL_IO_TRACK_OS_FOR_DRIVER_WITH_BAD_BLOCKING

 	define on Darwin. [Bug 1457515]

 	* unix/configure: autoconf-2.13

 2006-04-05  Don Porter  <dgp@users.sourceforge.net>

 	* library/reg/pkgIndex.tcl:	Long overlooked bump to registry

 	* win/tclWinReg.c:		package version 1.1.4 (should have

 	been done for the Tcl 8.4.8 release!)

 	* library/dde/pkgIndex.tcl:	Long overlooked bump to dde package

 	* win/tclWinDde.c:		version 1.2.4 (should have been done

 	for the Tcl 8.4.8 release!)

 2006-04-05  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct): Allow empty

 	strings to be matched by the Tcl_GetIndexFromObj machinery, in the

 	same manner as any other key. [Bug 1464039]

 2006-04-04  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclPkg.c:	Revised Bug 1162286 fix from 2005-11-08 to be

 	* tests/pkg.test:	even more forgiving of package version

 	mismatch errors in [package ifneeded] commands, not even logging any

 	warning messages. This further reduces the

 	***POTENTIAL INCOMPATIBILITY*** noted for that change.

 2006-04-03  Andreas Kupries <andreask@activestate.com>

 	* generic/tclIO.c (ReadChars): Added check, panic and commentary to a

 	piece of code which relies on BUFFER_PADDING to create enough space at

 	the beginning of each buffer for the insertion of partial multibyte

 	data at the beginning of a buffer. Commentary explains why this code

 	is OK, and the panic is as a precaution if someone twiddled the

 	BUFFER_PADDING into uselessness.

 	* generic/tclIO.c (ReadChars): Temporarily suppress the use of

 	TCL_ENCODING_END set when EOF was reached while the buffer we are

 	converting is not truly the last buffer in the queue. Together with

 	the Utf bug below it was possible to completely wreck the buffer data

 	structures, eventually crashing Tcl. [Bug 1462248]

 	* generic/tclEncoding.c (UtfToUtfProc): Stop accessing memory beyond

 	the end of the input buffer when TCL_ENCODING_END is set and the last

 	bytes of the buffer start a multi-byte sequence. This bug contributed

 	to [Bug 1462248].

 2006-03-28  Jeff Hobbs  <jeffh@ActiveState.com>

 	* win/configure, win/tcl.m4: define MACHINE for gcc builds as well.

 	Needed by Tk for manifest generation.

 	* win/tclWinConsole.c: revert 2005-11-03 [Patch 1256872] change to add

 	win32 unicode console support as it broke the ability to modify the

 	encoding to the console.

 2006-03-28  Daniel Steffen  <das@users.sourceforge.net>

 	* unix/tclUnixFCmd.c (TclpObjNormalizePath): deal with *BSD/Darwin

 	realpath() converting relative paths into absolute paths. [Bug 1064247]

 2006-03-28  Vince Darley  <vincentdarley@sourceforge.net>

 	* generic/tclIOUtil.c: fix to nativeFilesystemRecord comparisons

 	(lesser part of [Bug 1064247])

 2006-03-27  Pat Thoyts  <patthoyts@users.sourceforge.net>

 	* win/tclWinTest.c:	Fixes for [Bug 1456373] (mingw-gcc issue) 

 2006-03-23  Don Porter  <dgp@users.sourceforge.net>

 	* tests/expr.test:	Nan self-inquality test silenced. [Bug 761471]

 2006-03-22  Don Porter  <dgp@users.sourceforge.net>

 	* changes:	updates for another RC.

 2006-03-18  Vince Darley  <vincentdarley@sourceforge.net>

 	* win/tclWinFile.c:

 	* win/tclWinTest.c:

 	* tests/fCmd.test:

 	* tests/winFCmd.test:

 	* tests/tcltest.test: Backport of [file writable] fixes for Windows

 	from HEAD. [Bug 1193497]

 2006-03-16  Andreas Kupries <andreask@activestate.com>

 	* doc/open.n: Documented the changed behaviour of 'a'ppend mode.

 	* tests/io.test (io-43.1 io-44.[1234]): Rewritten to be

 	self-contained with regard to setup and cleanup. [Bug 681793]

 	* generic/tclIOUtil.c (TclGetOpenMode): Added the flag O_APPEND to the

 	list of POSIX modes used when opening a file for 'a'ppend. This

 	enables the proper automatic seek-to-end-on-write by the OS. See [Bug

 	680143] for longer discussion.

 	* tests/ioCmd.test (iocmd-13.7.*): Extended the testsuite to check the

 	new handling of 'a'.

 2006-03-15  Andreas Kupries <andreask@activestate.com>

 	* tests/socket.test: Extended the timeout in socket-11.11 from 10 to

 	40 seconds to allow for really slow machines. Also extended

 	actual/expected results with value of variable 'done' to make it

 	clearer when a test fails due to a timeout. [Bug 792159]

 2006-03-14  Andreas Kupries <andreask@activestate.com>

 	* generic/tclPipe.c (TclCreatePipeline): Modified the processing of

 	pipebars to fail if the last bar is followed only by redirections.

 	[Bug 768659]

 2006-03-14  Andreas Kupries <andreask@activestate.com>

 	* doc/fconfigure.n: Clarified that -translation is binary is reported

 	as lf when queried, because it is identical to lf, except for the

 	special additional behaviour when setting it. [Bug 666770]

 2006-03-14  Andreas Kupries <andreask@activestate.com>

 	* win/tclWinPipe.c (Tcl_WaitPid): Backport of fix made to the head by

 	David Gravereaux in 2004. See ChangeLog entry 2004-01-19. [Bug 1381436]

 	Fixed a thread-safety problem with the process list. The delayed cut

 	operation after the wait was going stale by being outside the list

 	lock. It now cuts within the lock and does a locked splice for when it

 	needs to instead. [Bug 859820]

 2006-03-13  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclEncoding.c:	Report error when an escape encoding

 	is missing one of its sub-encodings [Bug 506653]

 	* unix/configure.in:	Revert change from 2005-07-26 that sometimes

 	* unix/configure:	added $prefix/share to the tcl_pkgPath.

 	See [Patch 1231015]. autoconf-2.13.

 2006-03-10  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

 	-- Summary of changes fixing [Bug 1437595] --

 	* generic/tclEvent.c: Cosmetic touches and identation

 	* generic/tclInt.h: Added TclpFinalizeSockets() call.

 	* generic/tclIO.c: Calls TclpFinalizeSockets() as part of the

 	TclFinalizeIOSubsystem().

 	* unix/tclUnixSock: Added no-op TclpFinalizeSockets().

 	* mac/tclMacSock.c:

 	* win/tclWinPipe.c

 	* win/tclWinSock.c: Finalization of the sockets/pipes is now solely

 	done in TclpFinalizeSockets() and TclpFinalizePipes() and not over the

 	thread-exit handler, because the order of actions the Tcl generic core

 	will impose may result in cores/hangs if the thread exit handler tears

 	down corresponding subsystem(s) too early.

 2006-03-10  Vince Darley  <vincentdarley@sourceforge.net>

 	* win/tclWin32Dll.c: 

 	* win/tclWinInt.h: 

 	* win/tclWinFile.c: backported some fixes from HEAD relating to 'file

 	readable' and 'file writable', but main 'file writable' bug still

 	outstanding.

 	auto-completion test. [Bug 1422736]

 2006-01-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* unix/tclUnixInit.c (TclpInitPlatform): Improved conditions on when

 	to update the FP rounding mode on FreeBSD, taken from FreeBSD port.

 2006-01-23  Miguel Sofer  <msofer@users.sf.net>

 	* generic/tclStringObj.c (Tcl_GetRange): 

 	* tests/stringTest (string-12.21):fixed incorrect handling of internal

 	rep in Tcl_GetRange. Thanks to twylite and Peter Spjuth. [Bug 1410553]

 2006-01-16  Reinhard Max  <max@suse.de>

 	* generic/tclPipe.c (FileForRedirect): Prevent nameString from being

 	freed without having been initialized.

 	* tests/exec.test: Added a test for the above.

 2006-01-12  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

 	* generic/tclIOUtil.c (Tcl_FSGetInternalRep): fixed potential

 	overwriting of already freed memory which caused all kinds of (rare

 	but reproducible) coredumps all over the place.

 2006-01-11  Don Porter  <dgp@users.sourceforge.net>

 	* tests/error.test (error-7.0):	Test the timing of write traces on

 	::errorInfo. [Bug 1397843]

 2006-01-10  Daniel Steffen  <das@users.sourceforge.net>

 	* unix/configure:    add caching, use AC_CACHE_CHECK instead of

 	* unix/configure.in: AC_CACHE_VAL where possible, consistent message

 	* unix/tcl.m4:	     quoting, sync relevant tclconfig/tcl.m4 and HEAD

 	changes and gratuitous formatting differences, fix SC_CONFIG_MANPAGES

 	with default argument, Darwin improvements to SC_LOAD_*CONFIG.

 2006-01-09  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclNamesp.c (NamespaceInscopeCmd):	[namespace inscope]

 	* tests/namespace.test:	commands were not reported by [info level].

 	[Bug 1400572]

 2005-12-20  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* generic/tclThreadAlloc.c (Tcl_GetMemoryInfo): Format values as longs

 	and not ints, so they are less likely to wrap on 64-bit machines.

 2005-12-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* doc/Tcl.n: Clarify what is going on in variable substitution

 	following thread on comp.lang.tcl.

 2005-12-14  Daniel Steffen  <das@users.sourceforge.net>

 	* generic/tclIOUtil.c: workaround gcc warning "comparison is always

 	* generic/tclTest.c:   false due to limited range of data type".

 	* unix/configure.in: run check for fts API on all platforms, since

 	Linux glibc2 and *BSDs also have this and using fts is more efficient

 	than recursive opendir/readdir (sync with HEAD).

 	* unix/configure: regen.

 2005-12-12  Jeff Hobbs  <jeffh@ActiveState.com>

 	* unix/tcl.m4, unix/configure: Fix sh quoting error reported in

 	bash-3.1+ [Bug 1377619] (schafer)

 2005-12-12  Reinhard Max  <max@suse.de>

 	* generic/tclExecute.c (ExprAbsFunc): fixed the abs(MIN_INT) case so

 	that it doesn't break on compilers that don't assume integers to wrap

 	around (e.g. gcc-4.1.0).

 2005-12-09  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

 	* tests/lsearch.test (lsearch-10.8..10): If the -start is off the end,

 	* generic/tclCmdIL.c (Tcl_LsearchObjCmd): searching should find

 	nothing at all. [Bug 1374778]

 2005-12-05  Daniel Steffen  <das@users.sourceforge.net>

 	*** 8.4.12 TAGGED FOR RELEASE ***

 	* unix/configure: regen.

 2005-11-29  Jeff Hobbs  <jeffh@ActiveState.com>

 	* win/tcl.m4:	   Add build support for Windows-x64 builds.

 	* win/configure:   --enable-64bit now accepts =amd64|ia64 for

 	* win/Makefile.in: Windows 64-bit build variants (default: amd64)

 	* win/makefile.vc: [Bug 1369597]

 	* generic/tclObj.c (Tcl_GetWideIntFromObj): Add more efficient

 	conversion to wides from normal ints. [Bug 1310081]

 	* generic/tclCmdIL.c (Tcl_LsearchObjCmd): Allow [lsearch -regexp] to

 	process REs that contain backreferences. This expensive mode of

 	operation is only used if the RE would otherwise cause a compilation

 	failure. [Bug 1366683]

 2005-11-28  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* win/tclWinSock.c (CreateSocket): Applied [Patch 1353853] to prevent

 	reads of uninitialized variables during cleanup.

 2005-11-27  Daniel Steffen  <das@users.sourceforge.net>

 	* unix/tcl.m4 (Darwin): add 64bit support, check for Tiger copyfile(),

 	add CFLAGS to SHLIB_LD to support passing -isysroot in env(CFLAGS) to

 	configure (flag can't be present twice, so can't be in both CFLAGS and

 	LDFLAGS during configure), don't use -prebind when deploying on 10.4,

 	define TCL_IO_TRACK_OS_FOR_DRIVER_WITH_BAD_BLOCKING (rdar://3171542).

 	(SC_ENABLE_LANGINFO, SC_TIME_HANDLER): add/fix caching, fix obsolete

 	autoconf macros. Sync with tk/unix/tcl.m4, sync whitespace with HEAD.

 	* unix/configure.in: fix obsolete autoconf macros, sync gratuitous

 	formatting/ordering differences with tk/unix/configure.in.

 	* unix/Makefile.in: add CFLAGS to tclsh/tcltest link to make

 	executable linking the same as during configure (needed to avoid

 	loosing any linker relevant flags in CFLAGS, in particular flags that

 	can't be in LDFLAGS). Avoid concurrent linking of tclsh and compiling

 	of tclTestInit.o or xtTestInit.o during parallel make.

 	(checkstubs, checkdoc, checkexports): dependency and Darwin fixes

 	* unix/tclLoadDyld.c (TclpDlopen): [Bug 1204237] use

 	NSADDIMAGE_OPTION_WITH_SEARCHING on second NSAddImage only.

 	(TclGuessPackageName): should not be MODULE_SCOPE.

 	(TclpLoadMemory): ppc64 and endian (i386) fixes, add support for

 	loading universal (fat) bundles from memory.

 	* unix/tclUnixPort.h:

 	* unix/tclUnixFCmd.c: add support for new Tiger copyfile() API to

 	enable copying of xattrs & ACLs by [file copy].

 	* generic/tcl.h: add Darwin specifc configure overrides for TCL_WIDE

 	defines to support fat compiles of ppc and ppc64 at the same time,

 	(replaces Darwin CVS fix by emoy, rdar://3693001).

 	add/correct location of version numbers in macosx files.

 	* generic/tclInt.h: clarify fat compile comment.

 	* unix/tclUnixPort.h: add Darwin specifc configure overrides to

 	support fat compiles, where configure runs only once for multiple

 	architectures (replaces Darwin CVS fix by emoy, rdar://3693001).

 	* macosx/tclMacOSXBundle.c:

 	* macosx/tclMacOSXNotify.c:

 	* unix/tclUnixNotfy.c: fix #include order to support compile time

 	* unix/tclUnixPort.h:  override of HAVE_COREFOUNDATION in

 	tclUnixPort.h when building for ppc64

 	* macosx/Tcl.pbproj/default.pbxuser (new file):

 	* macosx/Tcl.pbproj/jingham.pbxuser:

 	* macosx/Tcl.pbproj/project.pbxproj: sync with HEAD.

 	* macosx/README: clarification/cleanup, sync with HEAD, document

 	universal (fat) builds via CFLAGS (i.e. all of ppc ppc64 i386 at once).

 	* macosx/Makefile: add support for reusing configure cache, build

 	target fixes, remove GENERIC_FLAGS override now handled by tcl.m4.

 	* generic/tclIOUtil.c:

 	* generic/tclRegexp.c:

 	* generic/tclVar.c: declare globals used only in own file as static

 	* unix/configure: regen.

 2005-11-20  Joe English  <jenglish@users.sourceforge.net>

 	* generic/tclStubLib.c: Don't set tclStubsPtr to 0 when

 	Tcl_PkgRequireEx() fails [Fix for [Bug 1091431] "Tcl_InitStubs failure

 	crashes wish"]

 2005-11-18  Miguel Sofer <msofer@users.sf.net>

 	* tests/trace.test (trace-34.5): [Bug 1047286], added a second test

 	illustrating the role of "ns in callStack" in the ns's visibility

 	during deletion traces.

 	* generic/tclBasic.c (Tcl_DeleteCommandFromToken):

 	* generic/tclCmdMZ.c (TraceCommandProc):

 	* generic/tclInt.h (NS_KILLED):

 	* generic/tclNamesp.c (Tcl_DeleteNamespace

 	* tests/namespace.test (namespace-7.3-6):

 	* tests/trace.test (trace-20.13-16): fix [Bugs 1355942/1355342].

 2005-11-18  Jeff Hobbs  <jeffh@ActiveState.com>

 	* generic/tclIO.c (TclFinalizeIOSubsystem): preserve statePtr until we

 	netrieve next statePtr from it.

 2005-11-18  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclPkg.c:	Revised Bug 1162286 fix from 2005-11-08 to be

 	* tests/pkg.test:	more forgiving of package version mismatch

 	errors in [package ifneeded] commands. This reduces the

 	***POTENTIAL INCOMPATIBILITY*** noted for that change.

 2005-11-18  Andreas Kupries <andreask@activestate.com>

 	* generic/tclIO.c (TclFinalizeIOSubsystem): Applied Pat Thoyts' patch

 	for [Bug 1359094]. This moves the retrieval of the next channel state

 	to the end of the loop, as the called closeproc may close other

 	channels, i.e., modify the list we are iterating, invalidating any

 	pointer retrieved earlier.

 2005-11-18  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

 	* library/http/http.tcl (http::geturl): Improved syntactic validation

 	of URLs, and better error messages in some cases. [Bug 1358369]

 	* changes:		Update changes for 8.4.12 release

 2005-11-15  Kevin B. Kenny  <kennykb@acm.org>

 	* tests/cmdAH.test: Backported the fix for [Bug 926016] because of

 	* win/tclWinFile.c: a repeated bug report in 8.4 [Bug 1353840].

 	Windows [file mtime] will now return seconds from the Posix epoch

 	correctly (except for FAT32 file systems after a DST change without a

 	reboot - for which there is no help). A side effect is that file times

 	will appear different in Tcl from the way they do in Windows Explorer

 	or a 'dir' listing, because the Microsoft tools get the DST state

 	wrong in the listings.

 2005-11-09  Kevin B. Kenny  <kennykb@acm.org>

 	* generic/tclTimer.c: Changed [after] so that it behaves correctly

 	* tests/timer.test:   with negative arguments. [Bug 1350293]

 2005-11-08  Jeff Hobbs  <jeffh@ActiveState.com>

 	* unix/tclUnixFCmd.c (MAX_READDIR_UNLINK_THRESHOLD): reduce to 130

 	based on errors seen on OS X 10.3 with lots of links in a dir. [Bug

 	1034337 followup]

 2005-11-08  Don Porter  <dgp@users.sourceforge.net>

 	* tests/expr.test:	Portable tests expr-46.13-18 [Bug 1341368]

 	* generic/tclPkg.c:	Corrected inconsistencies in the value returned

 	* tests/pkg.test:	by Tcl_PkgRequire(Ex) so that the returned

 	values will always agree with what is stored in the package database.

 	This way repeated calls to Tcl_PkgRequire(Ex) have the same results.

 	Thanks to Hemang Lavana. [Bug 1162286]

 	***POTENTIAL INCOMPATIBILITY***: Incompatible with those existing

 	packages that are accustomed to the [package] command forgiving

 	their bugs.

 	* tests/namespace.test (25.7,8):	Backport test of knownBug.

 2005-11-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* generic/tclCmdMZ.c (TclTraceVariableObjCmd, TraceVarProc): Applied

 	Miguel's fix for [Bug 1348775]. It is not quite as elegant as the one

 	applied to the HEAD, but it is easier to use it rather than fully

 	backporting.

 2005-11-07  Miguel Sofer <msofer@users.sf.net>

 	* tests/trace.test (trace-13.2-4): added tests to detect leak, see

 	[Bug 1348775].

 2005-11-04  Don Porter  <dgp@users.sourceforge.net>

 	* unix/tcl.m4:	Added code to enable [load] on LynxOS. Thanks to

 	heidibr@users.sf.net for the patch. [Bug 1163896]

 	* unix/configure:	autoconf-2.13.

 2005-11-04  Pat Thoyts  <patthoyts@users.sourceforge.net>

 	* win/tclWinPipe.c: Applied [Patch 1267871] by Matt Newman which

 	* win/tclWinPort.h: provides extended error code support.

 	* tests/exec.test:  Wrote some tests for this feature.

 2005-11-04  Kevin Kenny  <kennykb@acm.org>

 	* generic/tclGetDate.y: Added abbreviations for the Korean timezone.

 	* generic/tclDate.c:	Regenerated.

 	* compat/strftime.c: Fixed a problem where the name of the time zone

 	was double-converted from system encoding to UTF-8. Thanks to the

 	anonymous submitter of [Bug 1317477] for the report and the patch.

 2005-11-04  Miguel Sofer <msofer@users.sf.net>

 	* generic/tclInt.h:

 	* generic/tclNamesp.c:

 	* generic/tclVar.c: fix for [Bugs 1338280/1337229]. Thanks Don.

 	* tests/trace.test: fix duplicate test numbers

 2005-11-03  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclUnixInit.c (TclpSetInitialEncodings):	Modified so

 	that multiple calls can continue to atttempt to properly set the

 	system encoding. Needed for Tclkit to properly support non-default

 	encodings. Thanks to Yaroslav Schekin. [Bug 1201171]

 2005-11-03  Pat Thoyts  <patthoyts@users.sourceforge.net>

 	* win/tclWin32Dll.c:   Backported Anton Kovalenko's [Patch 1256872]

 	* win/tclWinConsole.c: to give unicode console support on

 	* win/tclWinInt.h:     suitable systems (eg: NT/XP)

 2005-11-01  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclCmdMZ.c (TclCheckExecutionTraces):	Corrected mistaken

 	assumption that all command traces are set at the script level.

 	Report/fix from Jacques H. de Villiers. [Bug 1337941]

 	* tests/expr-old.test (expr-32.52):	Use int(.) to restrict result

 	of left shift to the C long range.

 2005-10-29  Mo DeJong  <mdejong@users.sourceforge.net>

 	* tests/expr.test: Fix problems in new round() tests that lead to

 	correct result only on 32 bit long systems. [Bug 1341368]

 2005-10-29  Miguel Sofer <msofer@users.sf.net>

 	* generic/tclCmdMZ.c (TraceVarProc): [Bug 1337229], partial fix.

 	Ensure that a second call with TCL_TRACE_DESTROYED does not lead to a

 	second call to Tcl_EventuallyFree(). It is still true that that second

 	call should not happen, so the bug is not completely fixed.

 	* tests/trace.test (test-18.3-4): added tests for [Bugs 1337229 and

 	1338280].

 2005-10-27  Mo DeJong  <mdejong@users.sourceforge.net>

 	* generic/tclExecute.c (ExprRoundFunc): Fix typo where number before

 	rounding is compared with smallest integer instead of number after

 	rounding. This fix does not change the results of any tests.

 	* tests/expr.test: Add round() tests for cases near the min and max

 	int values.

 	* tests/util.test: Remove pointless warning code about testobj command

 	Tcl_SetVar2Ex, Tcl_ObjSetVar2 or Tcl_SetObjErrorCode with a 0-ref new

 	value. It is not possible to handle error returns correctly in that

 	case [Bug 1334947], one has the choice of leaking the object in some

 	cases, or else risk crashing in some others.

 2005-10-22  Miguel Sofer <msofer@users.sf.net>

 	* generic/tclExecute.c (INST_CONCAT): disable the optimisation for

 	wide integers. [Bug 1251791]

 2005-10-14  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

 	* generic/tclIO.c (Tcl_ClearChannelHandlers): removed change dated

 	2005-10-04 below. Look into [Bug 1323992] for detailed discussion.

 2005-10-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Stop [format] from seeing

 	the difference between ints and wides. [Bug 1284178]

 2005-10-13  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

 	* generic/tclIO.c (Tcl_ClearChannelHandlers): temporary

 	ifdef TCL_THREADS changes done to de-activate pending

 	event processing when channel is being closed/cutted.

 2005-10-10  Jeff Hobbs  <jeffh@ActiveState.com>

 	* generic/tclInt.h: ensure MODULE_SCOPE decl

 2005-10-07  Jeff Hobbs  <jeffh@ActiveState.com>

 	* unix/tclUnixFCmd.c (TraverseUnixTree): Adjust 2004-11-11 change to

 	* tests/fCmd.test (fCmd-20.2):		 account for NFS special

 	files with a readdir rewind threshold. [Bug 1034337]

 2005-10-05  Andreas Kupries <andreask@activestate.com>

 	* generic/tclPipe.c (TclCreatePipeline): Fixed [Bug 1109294]. Applied

 	the patch provided by David Gravereaux.

 	* doc/CrtChannel.3: Fixed [Bug 1104682], by application of David

 	Welton's patch for it, and added a note about wideSeekProc.

 2005-10-05  Jeff Hobbs  <jeffh@ActiveState.com>

 	* tests/env.test (env-6.1):

 	* win/tclWinPort.h: define USE_PUTENV_FOR_UNSET 1

 	* generic/tclEnv.c (TclSetEnv, TclUnsetEnv): add

 	USE_PUTENV_FOR_UNSET to existing USE_PUTENV define to account for

 	various systems that have putenv(), but can't unset env vars with it.

 	Note difference between Windows and Linux for actually unsetting the

 	env var (use of '=').

 	Correct the resizing of the environ array. We assume that we are in

 	full ownership, but that's not correct. [Bug 979640]

 2005-10-04  Jeff Hobbs  <jeffh@ActiveState.com>

 	* win/tclWinSerial.c (SerialSetOptionProc): free argv [Bug 1067708]

 	* tests/http.test:		Do not URI encode -._~ according to

 	* library/http/http.tcl (init): RFC3986. [Bug 1182373] (aho)

 	* generic/tclIOUtil.c (TclFSNormalizeAbsolutePath): make static

 	* generic/tclEncoding.c (TclFindEncodings): make static

 	* unix/tclLoadShl.c (TclpDlopen): use DYNAMIC_PATH on second

 	shl_load only. [Bug 1204237]

 2005-10-04  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

 	* generic/tclIO.c (Tcl_ClearChannelHandlers): now deletes any

 	outstanding timer for the channel. Also, prevents events still

 	in the event queue from triggering on the current channel.

 	* generic/tclTimer.c (Tcl_DeleteTimerHandler): bail out early

 	if passed NULL argument.

 2005-09-30  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclMain.c:	Separate encoding conversion of command line

 	arguments from list formatting. [Bug 1306162]

 	* generic/tclBasic.c (ExprMathFunc): Restored "round away from zero"

 	* tests/expr.test (expr-46.*):	     behaviour to the "round"

 	function. Added test cases for the behavior, including the awkward

 	case of a number whose fractional part is 1/2-1/2ulp. [Bug 1275043]

 2005-08-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* generic/tclListObj.c (UpdateStringOfList): Stop uncontrolled and

 2005-08-16  Kevin Kenny <kennykb@acm.org>

 	* generic/tclEvent.c (Tcl_Finalize): Pushed Tcl_FinalizeLoad and

 	Tcl_ResetFilesystem down after Tcl_FinalizeThreadAlloc because

 	unloading DLLs can't happen while they still own TSD keys.

 	(This is a backport of changes made in the HEAD on 2005-08-10.)

 2005-08-05  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	configuration.

 2005-07-28  Jeff Hobbs  <jeffh@ActiveState.com>

 	like ">>this".	Note that Windows cannot support such access; there is

 	no equivalent flag on the handle that can be set at the kernel-call

 2005-07-26  Mo DeJong  <mdejong@users.sourceforge.net>

 	* unix/configure: Regen.

 	* unix/configure.in: Check for a $prefix/share directory and add it

 	the the package if found. This will check for Tcl packages in

 	/usr/local/share when Tcl is configured with the default dist install.

 	[Patch 1231015]

 2005-07-26  Don Porter  <dgp@users.sourceforge.net>

 	* doc/tclvars.n:	Improved $errorCode documentation. [RFE 776921]

 	* generic/tclBasic.c (Tcl_CallWhenDeleted):	Converted to use

 	per-thread counter, rather than a process global one that required

 	mutex protection. [RFE 1077194]

 	* generic/tclNamesp.c (TclTeardownNamespace):	Re-ordering so that

 	* tests/trace.test (trace-34.4):	command delete traces fire

 	while the command still exists. [Bug 1047286]

 2005-07-24  Mo DeJong  <mdejong@users.sourceforge.net>

 	* unix/tcl.m4 (SC_PROG_TCLSH, SC_BUILD_TCLSH):

 	* win/tcl.m4 (SC_PROG_TCLSH, SC_BUILD_TCLSH):

 	Split confused search for tclsh on PATH and build and install

 	locations into two macros. SC_PROG_TCLSH searches just the PATH.

 	SC_BUILD_TCLSH determines the name of the tclsh executable in the Tcl

 	build directory. [Bug 1160114], [Patch 1244153]

 2005-07-22  Don Porter  <dgp@users.sourceforge.net>

 	* library/auto.tcl:	Updates to the Tcl script library to make

 	* library/history.tcl:	use of Tcl 8.4 feautures.  Thanks to

 	* library/init.tcl:	Patrick Fradin for prompting on this.

 	* library/package.tcl:	[Patch 1237755]

 	* library/safe.tcl:

 	* library/word.tcl:

 2005-07-07  Jeff Hobbs  <jeffh@ActiveState.com>

 	* unix/tcl.m4, unix/configure: Backported [Bug 1095909], removing

 	* unix/tclUnixPort.h:	       any use of readdir_r as it is not

 	* unix/tclUnixThrd.c:	       necessary and just confuses things.

 2005-07-05  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclCmdAH.c:	 New "encoding" Tcl_ObjType (not registered)

 	* generic/tclEncoding.c: that permits longer lifetimes of the

 	* generic/tclInt.h:	 Tcl_Encoding values kept as intreps of

 	Tcl_Obj's.  Reduces the need for repeated reading of encoding

 	definition files from the filesystem. [Bug 1077262]

 	* generic/tclNamesp.c:	Allow for [namespace import] of a command

 	* tests/namespace.test: over a previous [namespace import] of itself

 	without throwing an error. [RFE 1230597]

 2005-07-01  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

 	* unix/tclUnixNotfy.c: protect against spurious wake-ups while waiting

 	on the condition variable when tearing down the notifier thread. [Bug

 	1222872]

 2005-06-27  Don Porter  <dgp@users.sourceforge.net>

 	*** 8.4.11 TAGGED FOR RELEASE ***

 	* library/auto.tcl:	Reverted to Revision 1.12.2.3 (Tcl 8.4.9).

 	Restores the (buggy) behavior of [auto_reset] that fails to clear

 	away auto-loaded commands from non-global namespaces.  Fixing this

 	bug exposed an unknown number of buggy files out there (including at

 	least portions of the Tk script library) that cannot tolerate double

 	[source]-ing.  The burden of fixing these exposed bugs will not be

 	forced on package/extension/application authors until Tcl 8.5.

 2005-06-24  Kevin Kenny  <kennykb@acm.org>

 	* generic/tclEvent.c (Tcl_Finalize):

 	* generic/tclInt.h:

 	* generic/tclPreserve.c (TclFinalizePreserve): Changed the

 	finalization logic so that Tcl_Preserve finalizes after exit

 	handlers run; a lot of code called from Tk's exit handlers

 	presumes tha Tcl_Preserve will still work even from an exit

 	handler.  Also, made the assertion check that no exit handlers

 	are created in Tcl_Finalize conditional on TCL_MEM_DEBUG to

 	avoid spurious panics in the "stable" release.

 2005-06-24  Don Porter  <dgp@users.sourceforge.net>

 	* library/auto.tcl:	Make file safe to re-[source] without

 	destroying registered auto_mkindex_parser hooks.

 2005-06-23  Daniel Steffen  <das@users.sourceforge.net>

 	* tools/tcltk-man2html.tcl: fixed useversion glob pattern to accept

 	multi-digit patchlevels.

 2005-06-23  Kevin Kenny  <kennykb@acm.org>

 	* win/tclWinChan.c: More rewriting of __asm__ blocks that

 	* win/tclWinFCmd.c: implement SEH in GCC, because mingw's

 	gcc 3.4.2 is not as forgiving of violations committed by

 	the old code and caused panics. [Bug 1225957]

 2005-06-23  Daniel Steffen  <das@users.sourceforge.net>

 	* unix/Makefile.in (install-private-headers): rewrite tclPort.h when

 	installing private headers to remove ../unix relative #include path to

 	tclUnixPort.h (which is incorrect at the installed location).

 2005-06-22  Kevin Kenny <kennykb@acm.org>

 	* generic/tclInt.h:			    Changed the finalization

 	* generic/tclEvent.c (Tcl_Finalize):	    logic to defer the

 	* generic/tclIO.c (TclFinalizeIOSubsystem): shutdown of the pipe

 	* unix/tclUnixPipe.c (TclFinalizePipes):    management until after

 	* win/tclWinPipe.c (TclFinalizePipes):	    all channels have been

 	    closed, in order to avoid a situation where the Windows

 	    PipeCloseProc2 would re-establish the exit handler after exit

 	    handlers had already run, corrupting the heap. [Bug 1225727]

 	Corrected a read of uninitialized memory in PipeCloseProc2, which (at

 	least on certain configurations) caused a great number of tests to

 	either fail or hang. [Bug 1225044]

 2005-06-22  Andreas Kupries <andreask@activestate.com>

 	* generic/tclInt.h: Followup to change made on 2005-06-18 by Daniel

 	Steffen. There are compilers (*) who error out on the redefinition of

 	WORDS_BIGENDIAN. We have to undef the previous definition (on the

 	command line) first to make this acceptable. (*): AIX native.

 2005-06-22  Don Porter  <dgp@users.sourceforge.net>

 	* win/tclWinFile.c:	Potential buffer overflow. [Bug 1225571]

 	Thanks to Pat Thoyts for discovery and fix.

 	* tests/safe.test:	Backport performance improvement from

 	reduced $::auto_path.

 2005-06-21  Pat Thoyts  <patthoyts@users.sourceforge.net>

 	* tests/winDde.test: Added some waits to the dde server script to

 	let event processing run after we create the dde server and before

 	we exit the server process. This avoids 'server did not respond'

 	errors.

 2005-06-21  Kevin Kenny  <kennykb@acm.org>

 	* generic/tclFileName.c: Corrected a problem where a directory name

 	containing a colon can crash the process on Windows [Bug 1194458]

 	* tests/fileName.test: Added test for [file split] and [file join]

 	with a name containing a colon.

 	* win/tclWinPipe.c: Reverted davygrvy's changes of 2005-04-19;

 	they cause multiple failures in io.test. [Bug 1225044, still open]

 2005-06-21  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclBasic.c:	Made the walk of the active trace list aware

 	* generic/tclCmdMZ.c:	of the direction of trace scanning, so the

 	* generic/tclInt.h:	proper correction can be made. [Bug 1224585]

 	* tests/trace.test (trace-34.2,3):

 	* generic/tclBasic.c (Tcl_DeleteTrace):	Added missing walk of the

 	* tests/trace.test (trace-34.1):	list of active traces to

 	cleanup references to traces being deleted. [Bug 1201035]

 2005-06-20  Don Porter  <dgp@users.sourceforge.net>

 	* doc/FileSystem.3: added missing Tcl_GlobTypeData documentation [Bug

 	935853]

 2005-06-18  Daniel Steffen  <das@users.sourceforge.net>

 	* generic/tclInt.h: ensure WORDS_BIGENDIAN is defined correctly with

 	fat compiles on Darwin (i.e. ppc and i386 at the same time), the

 	configure AC_C_BIGENDIAN check is not sufficient in this case because

 	a single run of the compiler builds for two architectures with

 	different endianness.

 	* unix/tcl.m4 (Darwin): add -headerpad_max_install_names to LDFLAGS to

 	ensure we can always relocate binaries with install_name_tool.

 	* unix/configure: autoconf-2.13

 2005-06-18  Don Porter  <dgp@users.sourceforge.net>

 	* changes:		Update changes for 8.4.11 release

 	* README:		Bump version number to 8.4.11

 2005-06-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Fix for [Bug 1154163]; only

 	* tests/format.test: insert 'l' modifier when it is needed.

 2005-06-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* unix/tclUnixNotfy.c (Tcl_FinalizeNotifier): Add dummy variable

 	so threaded build compiles.

 2005-06-06  Kevin B. Kenny  <kennykb@acm.org>

 	* win/tclWin32Dll.c: Corrected another buglet in the assembly code for

 	stack probing on Win32/gcc. [Bug 1213678]

 2005-06-03  Daniel Steffen  <das@users.sourceforge.net>

 	*** 8.4.10 TAGGED FOR RELEASE ***

 	* unix/tclLoadDyld.c: fixed header conflict when building this file

 	with USE_TCL_STUBS.

 	* macosx/Makefile: fixed 'embedded' target.

 2005-06-02  Jeff Hobbs  <jeffh@ActiveState.com>

 	* unix/Makefile.in (html): add BUILD_HTML_FLAGS optional var

 	* tools/tcltk-man2html.tcl: add a --useversion to prevent

 	confusion when multiple Tcl source dirs exist.

 	* changes: updated for 8.4.10 release (porter)

 2005-05-31  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

 	* unix/tclUnixNotfy.c: the notifier thread is now created as

 	joinable thread and it is properly joined in Tcl_FinalizeNotifier.

 	This is an attempt to fix [Bug 1082283]

 2005-05-29  Jeff Hobbs  <jeffh@ActiveState.com>

 	* win/tclWinThrd.c (TclpFinalizeThreadData): move tlsKey defn

 	to top of file and clarify name (was 'key'). [Bug 1204064]

 2005-05-27  Jeff Hobbs  <jeffh@ActiveState.com>

 	* README:	    Bumped patchlevel to 8.4.10

 	* generic/tcl.h:

 	* tools/tcl.wse.in:

 	* unix/tcl.spec, unix/configure, unix/configure.in:

 	* win/configure, win/configure.in:

 2005-05-26  Daniel Steffen  <das@users.sourceforge.net>

 	* macosx/Makefile: moved & corrected EMBEDDED_BUILD check.

 	* unix/configure.in: corrected framework finalization to softlink

 	stub library to Versions/8.x subdir instead of Versions/Current.

 	* unix/configure: autoconf-2.13

 2005-05-25  Jeff Hobbs  <jeffh@ActiveState.com>

 	* generic/tclCmdMZ.c (Tcl_TimeObjCmd): add necessary cast

 	* unix/configure, unix/configure.in: ensure false Tcl.framework is

 	only created with --enable-framework

 2005-05-24  Daniel Steffen  <das@users.sourceforge.net>

 	* tests/env.test: added DYLD_FRAMEWORK_PATH to the list of env vars

 	that need to be handled specially.

 	* macosx/Makefile:

 	* macosx/README:

 	* macosx/Tcl-Info.plist.in (new file):

 	* unix/Makefile.in:

 	* unix/configure.in:

 	* unix/tcl.m4:

 	* unix/tclUnixInit.c: moved all Darwin framework build support from

 	macosx/Makefile into the standard unix configure/make buildsystem, the

 	macosx/Makefile is no longer required to build Tcl.framework (but its

 	functionality is still available for backwards compatibility).

 	* unix/configure: autoconf-2.13

 	* generic/tclIOUtil.c (TclLoadFile):

 	* generic/tclInt.h:

 	* unix/tcl.m4:

 	* unix/tclLoadDyld.c: added support for [load]ing .bundle binaries in

 	addition to .dylib's: .bundle's can be [unload]ed (unlike .dylib's),

 	and can be [load]ed from memory, e.g. directly from VFS without

 	needing to be written out to a temporary location first. [Bug 1202209]

 	* unix/configure: autoconf-2.13

 	* generic/tclCmdMZ.c (Tcl_TimeObjCmd): change [time] called with a

 	count > 1 to return a string with a float value instead of a rounded

 	off integer. [Bug 1202178]

 2005-05-20  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

 	* generic/tclParseExpr.c: removed unreferenced stack variable "errMsg"

 	probably included by fixing [Bug 1201589] (see below).

 2005-05-20  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclParseExpr.c:	Corrected parser to recognize all

 	boolean literals accepted by Tcl_GetBoolean, including prefixes like

 	"y" and "f", and to allow "eq" and "ne" as function names in the

 	proper context. [Bug 1201589]

 2005-05-19  Daniel Steffen  <das@users.sourceforge.net>

 	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier): fixed crashing

 	CFRelease of runLoopSource in Tcl_InitNotifier (reported by Zoran):

 	CFRunLoopAddSource doesn't CFRetain, so can only CFRelease the

 	runLoopSource in Tcl_FinalizeNotifier.

 2005-05-14  Daniel Steffen  <das@users.sourceforge.net>

 	* macosx/tclMacOSXBundle.c:

 	* unix/tclUnixInit.c:

 	* unix/tcl.m4 (Darwin): made use of CoreFoundation API configurable

 	and added test of CoreFoundation availablility to allow building on

 	ppc64, replaced HAVE_CFBUNDLE by HAVE_COREFOUNDATION; test for

 	availability of Tiger or later OSSpinLockLock API.

 	* unix/tclUnixNotfy.c:

 	* unix/Makefile.in:

 	* macosx/tclMacOSXNotify.c (new file): when CoreFoundation is

 	available, use new CFRunLoop based notifier: allows easy integration

 	with other event loops on Mac OS X, in particular the TkAqua Carbon

 	event loop is now integrated via a standard tcl event source (instead

 	of TkAqua upon loading having to finalize the exsting notifier and

 	replace it with its custom version). [Patch 1202052]

 	* tests/unixNotfy.test: don't run unthreaded tests on Darwin since

 	notifier may be using threads even in unthreaded core.

 	* unix/tclUnixPort.h:

 	* unix/tcl.m4 (Darwin): test for thread-unsafe realpath durning

 	configure, as Darwin 7 and later realpath is threadsafe.

 	* macosx/tclMacOSXBundle.c:

 	* unix/tclLoadDyld.c:

 	* unix/tclUnixInit.c: fixed gcc 4.0 warnings.

 	* unix/configure: autoconf-2.13

 2005-05-10  Jeff Hobbs  <jeffh@ActiveState.com>

 	* tests/string.test: string-10.[21-30]

 	* generic/tclCmdMZ.c (Tcl_StringObjCmd): add extra checks to

 	prevent possible UMR in unichar cmp function for string map.

 2005-05-06  Jeff Hobbs  <jeffh@ActiveState.com>

 	* unix/tcl.m4, unix/configure: correct Solaris 10 (5.10) check and

 	add support for x86_64 Solaris cc builds.

 2005-04-29  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

 	* doc/FileSystem.3: Backport of doc fix. [Bug 1172401]

 2005-04-27  Don Porter  <dgp@users.sourceforge.net>

 	* library/init.tcl:	Corrected flaw in interactive command

 	* tests/main.test:	auto-completion. [Bug 1191409]

 	* tests/unixInit.test (7.1):	Alternative fix for the

 	2005-04-22 commit.

 2005-04-25  Daniel Steffen  <das@users.sourceforge.net>

 	* compat/string.h: fixed memchr() protoype for __APPLE__ so that we

 	build on Mac OS X 10.1 again.

 	* generic/tclNotify.c (TclFinalizeNotifier): fixed notifier not being

 	finalized in unthreaded core (was testing for notifier initialization

 	in current thread by checking thread id != 0 but thread id is always 0

 	in untreaded core).

 	* unix/tclUnixNotfy.c (Tcl_WaitForEvent): sync with HEAD: only declare

 	and use timeout var in unthreaded core.

 	* unix/Makefile.in: added @PLAT_SRCS@ to SRCS and split out

 	NOTIFY_SRCS from UNIX_SRCS for parity with UNIX_OBJS & NOTIFY_OBJS.

 	* unix/configure.in: only run check for broken strstr implementation

 	if AC_REPLACE_FUNCS(strstr) hasn't already determined that strstr is

 	unavailable, otherwise compat/strstr.o will be used twice (resulting

 	in duplicate symbol link errors on Mac OS X 10.1)

 	* unix/tcl.m4 (Darwin): added configure checks for recently added

 	linker flags -single_module and -search_paths_first to allow building

 	with older tools (and on Mac OS X 10.1), use -single_module in

 	SHLIB_LD and not just T{CL,K}_SHLIB_LD_EXTRAS, added unexporting from

 	Tk of symbols from libtclstub to avoid duplicate symbol warnings,

 	added PLAT_SRCS definition for Mac OS X.

 	(SC_MISSING_POSIX_HEADERS): added caching of dirent.h check.

 	(SC_TCL_64BIT_FLAGS): fixed 'checking for off64_t' message output.

 	* unix/configure: autoconf-2.13

 2005-04-22  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclCmdMZ.c:	Corrected intrep-dependence of

 	* tests/string.test:	[string is boolean] [Bug 1187123]

 2005-04-22  Daniel Steffen  <das@users.sourceforge.net>

 	* tests/unixInit.test (7.1): fixed failure when running tests with

 	-tmpdir arg not set to working dir.

 2005-04-20  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclGet.c (Tcl_GetInt):	Corrected error that did not

 	* generic/tclObj.c (Tcl_GetIntFromObj): permit 0x80000000 to be

 	recognized as an integer on TCL_WIDE_INT_IS_LONG systems [Bug 1090869]

 2005-04-19  Jeff Hobbs  <jeffh@ActiveState.com>

 	* tests/winPipe.test (winpipe-6.2): remove -blocking 1 as this one

 	can truly block.

 2005-04-19  David Gravereaux <davygrvy@pobox.com>

 	* win/tclWinPipe.c: The pipe channel driver now respects the -blocking

 	option when closing. The windows pipe driver now has the same behavior

 	as the UNIX side. This change 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.

 	* tests/winPipe.test (winpipe-6.1/2): added 'fconfigure $f -blocking

 	1' so the exit status can be acquired.

 2005-04-13  David Gravereaux <davygrvy@pobox.com>

 	* generic/tclIO.c (Tcl_SetChannelBufferSize): Lowest size limit

 	* tests/io.test:	changed from ten bytes to one byte. Need for

 	* tests/iogt.test:	this change was proven by Ross Cartlidge

 	<rossc@cisco.com> where [read stdin 1] was grabbing 10 bytes followed

 	by starting a child process that was intended to continue reading from

 	stdin. Even with -buffersize set to one, nine chars were getting lost

 	by the buffersize over reading for the native read() caused by [read].

 2005-04-12  Kevin B. Kenny  <kennykb@acm.org>

 	* compat/strstr.c: Added default definition of NULL to accommodate

 	building on systems with badly broken headers. [Bug 1175161]

 2005-04-09  Daniel Steffen  <das@users.sourceforge.net>

 	* macosx/README: updated requirements for OS & developer tool versions

 	+ other small fixes/cleanup.

 	* unix/tcl.m4 (Darwin): added -single_module linker flag to

 	TCL_SHLIB_LD_EXTRAS and TK_SHLIB_LD_EXTRAS.

 	* unix/configure: autoconf-2.13

 2005-04-05  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>

 	Set of changes correcting huge memory waste (not a leak) when a thread

 	exits. This has been introduced in 8.4.7 within an attempt to

 	correctly cleanup after ourselves when Tcl library is being unloaded

 	with the Tcl_Finalize() call.

 	This fixes the [Bug 1178445].

 	* generic/tclInt.h: added prototypes for TclpFreeAllocCache() and

 	TclFreeAllocCache()

 	* generic/tclThreadAlloc.c: modified TclFinalizeThreadAlloc() to

 	explicitly call TclpFreeAllocCache with the NULL-ptr as argument

 	signalling cleanup of private tsd key used only by the threading

 	allocator.

 	* unix/tclUnixThrd.c: fixed TclpFreeAllocCache() to recognize when

 	being called with NULL argument. This is a signal for it to clean up

 	the tsd key associated with the threading allocator.

 	* win/tclWinThrd.c: renamed TclWinFreeAllocCache to TclpFreeAllocCache

 	and fixed to recognize when being called with NULL argument. This is a

 	signal for it to clean up the tsd key associated with the threading

 	allocator.

 2005-04-05  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclExecute.c (ExprSrandFunc):	Replaced incursions into the

 	* generic/tclUtil.c (TclGetIntForIndex): intreps of numeric types with

 	simpler calls of Tcl_GetIntFromObj and Tcl_GetLongFromObj, now that

 	those routines are better behaved wrt shimmering. [Patch 1177129]

 2005-03-29  Jeff Hobbs  <jeffh@ActiveState.com>

 	* win/tcl.m4, win/configure: do not require cygpath in macros to

 	allow msys alone as an alternative.

 	* win/tclWinTime.c (TclpGetDate): use time_t for 'time' [Bug 1163422]

 2005-03-18  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclCompCmds.c (TclCompileIncrCmd):	Corrected checks for

 	immediate operand usage to permit leading space and sign characters.

 	Restores more efficient bytecode for [incr x -1] that got lost in the

 	CONST string reforms of Tcl 8.4. [Bug 1165671]

 	* generic/tclBasic.c (Tcl_EvalEx,TclEvalTokensStandard):

 	* generic/tclCmdMZ.c (Tcl_SubstObj):

 	* tests/basic.test (basic-46.4):	Restored recursion limit

 	* tests/parse.test (parse-19.*):	testing in nested command

 	substitutions within direct script evaluation (Tcl_EvalEx) that got

 	lost in the parser reforms of Tcl 8.1. Added tests for correct

 	behavior. [Bug 1115904]

 2005-03-15  Vince Darley  <vincentdarley@users.sourceforge.net>

 	* generic/tclFileName.c:

 	* win/tclWinFile.c:

 	* tests/winFCMd.test: fix to 'file pathtype' and 'file norm' failures

 	on reserved filenames like 'COM1:', etc.

 2005-03-15  Kevin B. Kenny  <kennykb@acm.org>

 	* generic/tclClock.c:

 	* generic/tclDate.c:

 	* generic/tclGetDate.y:

 	* generic/tclInt.decls:

 	* unix/tclUnixTime.c:

 	* win/tclWinTime.c:	Replaced 'unsigned long' variable holding

 	times with 'Tcl_WideInt', to cope with systems on which a time_t is

 	wider than a long (Win64) [Bug 1163422]

 	* generic/tclIntDecls.h: Regen

 2005-03-15  Pat Thoyts  <patthoyts@users.sourceforge.net>

 	* unix/tcl.m4: Make it work on OpenBSD again. Imported patch

 	from the OpenBSD ports tree.

 2005-03-10  Don Porter  <dgp@users.sourceforge.net>

 	* generic/tclCmdMZ.c (TclCheckInterpTraces):	Corrected mistaken

 	cast of ClientData to (TraceCommandInfo *) when not warranted. Thanks

 	to Yuri Victorovich for the report. [Bug 1153871]

 2005-03-08  Jeff Hobbs  <jeffh@ActiveState.com>

 	* win/makefile.vc: clarify necessary defined vars that can come
