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:

	* unix/configure:	autoconf-2.13

	* win/configure:

	* generic/tclExecute.c (ExprSrandFunc):	Restore acceptance of wide

	* tests/expr-old.test: integer values by srand() [Bug 1480509]

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>

	* generic/tclTest.c:

	* 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:
