 boolean] is significantly more strict than Tcl_GetBooleanFromObj).

Subject: (::platform::LibcVersion): See [Bug 3599098]: Fixed the RE extracting
 the version to avoid issues with recent changes to the glibc banner. Now
 targeting a less variable part of the string. Bumped package to version
 1.0.11.

Subject: Cherrypick the refcount fixes and comments from mig-review.

I also find the revised "createPart2" values in *Lookup* calls appealing,
but I'm too fearful of breaking things without understanding the implications.
This approach just focuses on fixing the things I broke, without trying
to "fix" things long "broken" in multiple years of releases.

 duplicating an automaton in response to encountering a "wild" RE that hit the
 previous limit. Allow the limit (DUPTRAVERSE_MAX_DEPTH) to be set by defining
 its value in the Makefile. Problem reported by Jonathan Mills.

Subject: [Bug 3603553]: Ensure that data gets written to the underlying stream
 by compressing transforms when the amount of data to be written is one
 buffer's-worth; problem was particularly likely to occur when compressing
 large quantities of not-very-compressible data.

Many thanks to Piera Poggio (vampiera) for reporting.

Subject: Protect against multiple uses of a CompileEnv with only one
 initialization. Make TclFreeCompileEnv smarter about cleanup so all callers
 do not have to be. Revise TclSetByteCodeFromAny() so that when hookProc
 raises an error, bytecode is not generated.  This was rumored to cause
 crashes.

Subject: ifdef shuffling: TIOCMC[GS]ET ioctls are not specified by POSIX, so
 we can't assume they are present just because we HAVE_TERMIOS_H. Conversely,
 if they are present then the subsidiary flags TIOCM_{DTR|RTS} are almost
 certainly there as well, so that ifdeffery can be removed.

And lastly, ifdefs for TIOCSBRK/TIOCCBRK are still needed.
(Those are logically separate functions even though TIP#35
lumped them together with DTR and RTS in -ttycontrol.
POSIX provides tcsendbreak() for this purpose, but that
interface doesn't fit with the TIP#35 API.)

KNOWN DEFECT: if a hypothetical Unix system is missing TIOCMCGET
but has TIOCSBRK/TIOCCBRK, the latter function will nevertheless
be unavailable.  Accounting for this possibility does not strike
me as being worth the ifdefs.

From 43d41237ebb58132c881b9cb46aff91b825b7517 Mon Sep 17 00:00:00 2001
From: dgp <dgp@users.sourceforge.net>

Subject: New scheme for keeping the per-process tcl_precision value in sync
 without the need for mutex locks on every read.  Uses adapted
 ProcessGlobalValue machinery backported from Tcl 8.5 where it's been working
 without reported problems.  Thanks to Phil Brooks for reporting on tests
 which highlight the thread performance problems raised by the old scheme, and
 to Clif Flynt for further testing pointing the finger at tcl_precision locks
 as the main culprit.

Subject: Add dummy (undocumented) TclCanceled function in stub table (not
 exported as symbol or macro), which always returns TCL_OK. Needed for Tk
 8.5.14 when running in Tcl 8.6 for properly clean-up when a (Tcl 8.6) thread
 is canceled.

Subject: Implement Tcl_Pkg* functions as macro's around Tcl_Pkg*Ex. This saves
 stack space, is (marginally) faster, while still being fully up/down
 compatible. It makes pkgb.so loadable in "novem" without the need to change
 the Tcl_PkgProvide() call to Tcl_PkgProvideEx().

Subject: Implement Tcl_NewBooleanObj, Tcl_DbNewBooleanObj and
 Tcl_SetBooleanObj as macros using Tcl_NewIntObj, Tcl_DbNewLongObj and
 Tcl_SetIntObj. Starting with Tcl 8.5, this is exactly the same, it only
 eliminates code duplication.

-
-	* generic/tclVar.c (TclLookupSimpleVar):  Retrieve the number of

-
-2008-08-04  Don Porter  <dgp@users.sourceforge.net>
-
-	* generic/tclExecute.c:	Stopped faulty double-logging of errors to
-	* tests/execute.test:	stack trace when a compile epoch bump triggers
-	fallback to direct evaluation of commands in a compiled script.
-	[Bug 2037338]
-
-2008-07-30  Don Porter  <dgp@users.sourceforge.net>
-
-	* generic/tclBasic.c:	Corrected the timing of when the flag
-	TCL_ALLOW_EXCEPTIONS is tested.
-
-2008-07-29  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclExecute.c:  fix [Bug 2030670] that cause
-	TclStackRealloc to panic on rare corner cases. Thx ajpasadyn for
-	diagnose and patch.
-
-2008-07-28  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclBasic.c: Added missing ref count when creating an empty
-	string as path (TclEvalEx). In 8.4 the missing code caused panics in
-	the testsuite. It doesn't in 8.5. I am guessing that the code path
-	with the missing the incr-refcount is not invoked any longer. Because
-	the bug in itself is certainly the same.
-
-2008-07-25  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tests/info.test (info-37.0): Add !singleTestInterp constraint;
-	(info-22.8, info-23.0): switch to glob matching to avoid sensitivity
-	to tcltest.tcl line number changes, remove knownBug constraint, fix
-	expected result. [Bug 1605269]
-
-2008-07-25  Andreas Kupries  <andreask@activestate.com>
-
-	* tests/info.test: Tests 38.* added, exactly testing the tracking of
-	location for uplevel scripts.
-
-	* generic/tclCompile.c (TclInitCompileEnv): Reorganized the
-	initialization of the #280 location information to match the flow in
-	TclEvalObjEx to get more absolute contexts.
-
-	* generic/tclBasic.c (TclEvalObjEx): Moved the pure-list optimization
-	out of the eval-direct code path to be done always, i.e. even when a
-	compile is requested. This way we do not loose the association between
-	#280 location information and the list elements, if any.
-
-2008-07-23  Andreas Kupries  <andreask@activestate.com>
-
-	* tests/info.test: Reordered the tests to have monotonously
-	increasing numbers.
-
-	* generic/tclBasic.c: Modified TclArgumentGet to reject pure lists
-	* generic/tclCmdIL.c: immediately, without search. Reworked setup
-	* generic/tclCompile.c: of eoFramePtr, doesn't need the line
-	* tests/info.test: information, more sensible to have everything on
-	line 1 when eval'ing a pure list. Updated the users of the line
-	information to special case this based on the frame type (i.e.
-	TCL_LOCATION_EVAL_LIST). Added a testcase demonstrating the new
-	behaviour.
-
-2008-07-22  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclBasic.c: Added missing function comments.
-
-	* generic/tclCompile.c: Made the new TclEnterCmdWordIndex
-	* generic/tclCompile.h: static, and ansified.
-
-	* generic/tclBasic.c: Reworked the handling of bytecode literals
-	* generic/tclCompile.c: for #280 to fix the abysmal performance
-	* generic/tclCompile.h: for deep recursion, replaced the linear
-	* generic/tclExecute.c: search through the whole stack with another
-	* generic/tclInt.h: hashtable and simplified the data structure used
-	by the compiler (array instead of hashtable). Incidentially this also
-	fixes the memory leak reported via [Bug 2024937].
-
-2008-07-21  Don Porter  <dgp@users.sourceforge.net>
-
-	* tests/encoding.test:  Make failing tests pass again. [Bug 1972867]
-
-2008-07-21  Andreas Kupries <andreask@activestate.com>
-
-	* generic/tclBasic.c: Extended the existing TIP #280 system (info
-	* generic/tclCmdAH.c: frame), added the ability to track the
-	* generic/tclCompCmds.c: absolute location of literal procedure
-	* generic/tclCompile.c: arguments, and making this information
-	* generic/tclCompile.h: available to uplevel, eval, and
-	* generic/tclInterp.c: siblings. This allows proper tracking of
-	* generic/tclInt.h: absolute location through custom (Tcl-coded)
-	* generic/tclNamesp.c: control structures based on uplevel, etc.
-	* generic/tclProc.c:

-
-2008-07-20  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
-
-	* generic/tclDictObj.c (SetDictFromAny): Make the list->dict
-	transformation a bit more efficient; modern dicts are ordered and so
-	we can round-trip through lists without needing the string rep at all.
-	* generic/tclListObj.c (SetListFromAny): Make the dict->list
-	transformation not lossy of internal representations and hence more
-	efficient. [Bug 2008248] (ajpasadyn) but using a more efficient patch.
-
-2008-07-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
-
-	* doc/DictObj.3: Fix error in example. [Bug 2016740]
-
-2008-07-08  Don Porter  <dgp@users.sourceforge.net>
-
-	* generic/tclGet.c:	Corrected out of date comments.

-
-2008-07-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
-
-	* doc/regexp.n, doc/regsub.n: Correct examples. [Bug 1982642]
-
-2008-07-04  Joe English  <jenglish@users.sourceforge.net>
-
-	* generic/tclEncoding.c(UtfToUtfProc): Avoid unwanted sign extension
-	when converting incomplete UTF-8 sequences. See [Bug 1908443] for
-	details.
-
-2008-07-03  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclIORChan.c (InvokeTclMethod): Fixed the memory leak
-	reported in [Bug 1987821]. Thanks to Miguel for the rpeort and Don
-	Porter for tracking the cause down.
-
-2008-07-03  Don Porter  <dgp@users.sourceforge.net>
-
-	* library/package.tcl:  Removed [file readable] testing from
-	[tclPkgUnknown] and friends. We find out soon enough whether a file is
-	readable when we try to [source] it, and not testing before allows us
-	to workaround the bugs on some common filesystems where [file
-	readable] lies to us. [Patch 1969717]

-
-	* unix/Makefile.in: Followup to my change of 2008-06-25, make code

-	* library/safe.tcl:	Safe Base to interact nicely with each other,
-	* library/init.tcl:	enabling requiring Tcl Modules in safe

-
-2008-06-24  Don Porter  <dgp@users.sourceforge.net>
-
-	* generic/tclPathObj.c: Fixed some internals management in the "path"
-	Tcl_ObjType for the empty string value. Problem led to a crash in the
-	command [glob -dir {} a]. [Bug 1999176].
-
-2008-06-23  Don Porter  <dgp@users.sourceforge.net>
-
-	* generic/tclPathObj.c: Fixed bug in Tcl_GetTranslatedPath() when
-	operating on the "Special path" variant of the "path" Tcl_ObjType
-	intrep. A full normalization was getting done, in particular, coercing
-	relative paths to absolute, contrary to what the function of
-	producing the "translated path" is supposed to do. [Bug 1972879]
-
-2008-06-19  Don Porter  <dgp@users.sourceforge.net>
-
-	* changes:	Update for 8.5.3 release.
-
-	* generic/tclInterp.c:	Fixed completely boneheaded mistake that
-	* tests/interp.test:	[interp bgerror $slave] and [$slave bgerror]
-	would always act like [interp bgerror {}]. [Bug 1999035]
-
-	* tests/chanio.test:	Corrected flawed tests revealed by a -debug 1

-
-	* generic/tclClock.c (ClockConvertlocaltoutcObjCmd): Removed left
-	over debug output.
-
-2008-06-17  Andreas Kupries  <andreask@activestate.com>
-
-	* doc/tm.n: Followup to changelog entry 2008-03-18 regarding
-	::tcl::tm::Defaults. Updated the documentation to not only mention
-	the new (underscored) form of environment variable names, but make
-	it the encouraged form as well. See [Bug 1914604].
-
-2008-06-17  Kevin Kenny  <kennykb@acm.org>
-
-	* generic/tclClock.c (ConvertLocalToUTC):
-	* tests/clock.test (clock-63.1): Fixed a bug where the
-	internal ConvertLocalToUTC command segfaulted if passed a
-	dictionary without the 'localSeconds' key.  To the best of
-	my knowledge, the bug was not observable in the [clock]
-	command itself.
-
-2008-06-16  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclCmdIL.c (TclInfoFrame): Backport of fix made on the
-	* tests/info.test: head branch :: Moved the code looking up the
-	information for key 'proc' out of the TCL_LOCATION_BC branch to
-	after the switch, this is common to all frame types. Updated the
-	testsuite to match. This was exposed by the 2008-06-08 commit
-	(Miguel), switching uplevel from direct eval to compilation. Fixes
-	[Bug 1987851].
-
-2008-06-12  Daniel Steffen  <das@users.sourceforge.net>
-
-	* unix/Makefile.in:		add complete deps on tclDTrace.h.
-
-	* unix/Makefile.in:		clean generated tclDTrace.h file.
-	* unix/configure.in (SunOS): 	fix static DTrace-enabled build.
-
-	* unix/tcl.m4 (SunOS-5.11): fix 64bit amd64 support with gcc & Sun cc.
-	* unix/configure: autoconf-2.59
-
-	* macosx/Tcl.xcodeproj/project.pbxproj:	add debug configs with gcov,
-	and with corefoundation disabled; updates and cleanup for Xcode 3.1 and
-	for Leopard.
-	* macosx/Tcl.xcode/project.pbxproj:	sync Tcl.xcodeproj changes.
-	* macosx/README:			document new build configs.
-
-2008-05-26  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tests/io.test (io-53.9): need to close chan before removing file.
-
-2008-05-23  Andreas Kupries  <andreask@activestate.com>
-
-	* win/tclWinChan.c (FileWideSeekProc): Accepted a patch by
-	Alexandre Ferrieux <ferrieux@users.sourceforge.net> to fix the
-	[Bug 1965787]. 'tell' now works for locations > 2 GB as well
-	instead of going negative.
-
-	* generic/tclIO.c (Tcl_SetChannelBufferSize): Accepted a patch by
-	* tests/io.test: Alexandre Ferrieux <ferrieux@users.sourceforge.net>
-	* tests/chanio.test: to fix the [Bug 1969953]. Buffersize outside
-	of the supported range are now clipped to nearest boundary instead
-	of ignored.
-
-2008-05-22  Don Porter  <dgp@users.sourceforge.net>
-
-	* generic/tclNamesp.c (Tcl_LogCommandInfo):	Restored ability to
-	handle the argument value length = -1.  Thanks to Chris Darroch for
-	discovering the bug and providing the fix.  [Bug 1968245].
-
-2008-05-21  Don Porter  <dgp@users.sourceforge.net>
-
-	* generic/tclParse.c (ParseComment):    The new TclParseAllWhiteSpace
-	* tests/parse.test (parse-15.60):       routine has no mechanism to
-	return the "incomplete" status of "\\\n" so calling this routine
-	anywhere that can be reached within a Tcl_ParseCommand call is a
-	mistake. In particular, ParseComment must not use it. [Bug 1968882]
-
-2008-05-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
-
-	* generic/tclNamesp.c (Tcl_SetNamespaceUnknownHandler): Corrected odd
-	logic for handling installation of namespace unknown handlers which
-	could lead too very strange things happening in the error case.
-
-2008-05-16  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclCompile.c: Fix crash with tcl_traceExec. Found and
-	fixed by Alexander Pasadyn [Bug 1964803].
-
-2008-05-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
-
-	* generic/tclCompCmds.c (TclCompileDictAppendCmd): Fix silly
-	off-by-one error that caused a crash every time a compiled 'dict
-	append' with more than one value argument was used. Found by Colin
-	McCormack.
-
-2008-04-26  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>
-
-	* generic/tclAsync.c: Tcl_AsyncDelete(): panic if attempt to locate
-	handler token fails. Happens when some other thread attempts to delete
-	somebody else's token.
-
-	Also, panic early if we find out the wrong thread attempting to delete
-	the async handler (common trap). As, only the one that created the
-	handler is allowed to delete it.
-
-2008-04-24  Andreas Kupries  <andreask@activestate.com>
-
-	* tests/ioCmd.test: Extended testsuite for reflected channel
-	implementation. Added test cases about how it handles if the rug is
-	pulled out from under a channel (= killing threads, interpreters
-	containing the tcl command for a channel, and channel sitting in a
-	different interpreter/thread.)
-
-	* generic/tclIORChan.c: Fixed the bugs exposed by the new testcases,
-	redone most of the cleanup and exit handling.
-
-2008-04-15  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclIO.c (CopyData): Applied another patch by Alexandre
-	* io.test (io-53.8a): Ferrieux <ferrieux@users.sourceforge.net>,
-	* chanio.test (chan-io-53.8a): to shift EOF handling to the async
-	part of the command if a callback is specified, should the channel
-	be at EOF already when fcopy is called. Testcase by myself.
-
-2008-04-14  Kevin B. Kenny <kennykb@acm.org>
-
-	* unix/tclUnixTime.c (NativeGetTime): Removed obsolete use of
-	'struct timezone' in the call to 'gettimeofday'. [Bug 1942197].
-	* tests/clock.test (clock-33.5, clock-33.5a, clock-33.8, clock-33.8a):
-	Added comments to the test that it can fail on a heavily loaded
-	system.
-
-2008-04-11  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tcl.h:	Bump version number to 8.5.3b1 to distinguish

-	* unix/configure.in:	8.5.3 releases.
-	* unix/tcl.spec:

-2008-04-10  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Keeping check for negative
-	values, changed to not be an error, but behave like the special
-	value -1 (copy all, default).
-
-	* tests/iocmd.test (iocmd-15.{12,13}): Removed.
-
-	* tests/io.test (io-52.5{,a,b}): Reverted last change, added
-	* tests/chanio.test (chan-io-52.5{,a,b}): comment regarding the
-	meaning of -1, added two more testcases for other negative values,
-	and input wrapped to negative.
-
-2008-04-09  Andreas Kupries  <andreask@activestate.com>
-
-	* tests/chanio.test (chan-io-52.5): Removed '-size -1' from test,
-	* tests/io.test (io-52.5): does not seem to have any bearing, and
-	  was an illegal value.
-
-	* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Added checking of -size
-	* tests/ioCmd.test (iocmd-15.{13,14}): value to reject negative
-	values, and values overflowing 32-bit signed. [Bug 1557855]. Basic
-	patch by Alexandre Ferrieux <ferrieux@users.sourceforge.net>, with
-	modifications from me to separate overflow from true negative
-	value. Extended testsuite.
-
-2008-04-08  Andreas Kupries  <andreask@activestate.com>
-
-	* tests/io.test (io-53.8): Fixed ordering of vwait and after
-	cancel. cancel has to be done after the vwait completes.
-
-2008-04-09  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tests/chanio.test (chan-io-53.8,53.9,53.10):	fix typo & quoting for

-
-2008-04-07  Andreas Kupries  <andreask@activestate.com>
-
-	* tests/io.test (io-53.10): Testcase for bi-directionaly fcopy.
-	* tests/chanio.test:
-	* generic/tclIO.c: Additional changes to data structures for fcopy
-	* generic/tclIO.h: and channels to perform proper cleanup in case
-	of a channel having two background copy operations running as is
-	now possible.
-
-	* tests/io.test (io-53.10): Testcase for bi-directionaly fcopy.
-	* generic/tclIO.c: Additional changes to data structures for fcopy
-	and channels to perform proper cleanup in case of a channel having
-	two background copy operations running as is now possible.
-
-2008-04-07  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclIO.c (BUSY_STATE, CheckChannelErrors,
-	TclCopyChannel): New macro, and the places using it. This change
-	allows for bi-directional fcopy on channels. [Bug 1350564]. Thanks
-	to Alexandre Ferrieux <ferrieux@users.sourceforge.net> for the
-	patch.
-
-2008-04-07  Reinhard Max  <max@suse.de>
-
-	* generic/tclStringObj.c (Tcl_AppendFormatToObj): Fix [format {% d}]
-	so that it behaves the same way as in 8.4 and as C's printf().
-	* tests/format.test: Add a test for '% d' and '%+d'.
-
-2008-04-05  Kevin B. Kenny  <kennykb@acm.org>
-
-	* tests/chanio.test (chan-io-53.9):
-	* tests/io.test (io-53.9): Made test cleanup robust against the
-	possibility of slow process shutdown on Windows.
-
-	* win/tcl.m4: Added -D_CRT_SECURE_NO_DEPRECATE and
-	-DCRT_NONSTDC_NO_DEPRECATE to the MSVC compilation flags so that
-	the compilation doesn't barf on perfectly reasonable Posix system
-	calls.
-	* win/configure: Manually patched (don't have the right autoconf
-	to hand).
-
-	* win/tclWinFile.c: (WinSymLinkDirectory): Fixed a problem that
-	Tcl was creating an NTFS junction point (IO_REPARSE_TAG_MOUNT_POINT)
-	but filling in the union member for a Vista symbolic link. We had
-	gotten away with this error because the union member
-	(SymbolicLinkReparseBuffer) was misdefined in this file and in the
-	'winnt.h' in early versions of MinGW. MinGW 3.4.2 has the correct
-	definition of SymbolicLinkReparseBuffer, exposing the mismatch,
-	and making tests cmdAH-19.4.1, fCmd-28.*, and filename-11.* fail.
-
-2008-04-04  Andreas Kupries  <andreask@activestate.com>
-
-	* tests/io.test (io-53.9): Added testcase for [Bug 780533], based
-	* tests/chanio.test: on Alexandre's test script. Also fixed
-	problem with timer in preceding test, was not canceled properly in
-	the ok case.
-
-2008-04-04  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclIORChan.c (ReflectOutput): Allow zero return from
-	write when input was zero-length anyway. Otherwise keept it an
-	error, and separate the message from 'written too much'.
-
-	* tests/ioCmd.test (iocmd-24.6): Testcase updated for changed
-	message.
-
-	* generic/tclIORChan.c (ReflectClose): Added missing removal of
-	the now closed channel from the reflection map. Before we could
-	crash the system by invoking 'chan postevent' on a closed
-	reflected channel, dereferencing the dangling pointer in the map.
-
-	* tests/ioCmd.test (iocmd-31.8): Testcase for the above.
-
-2008-04-03  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclIO.c (CopyData): Applied patch [Bug 1932639] to
-	* tests/io.test: prevent fcopy from calling -command synchronously
-	* tests/chanio.test: the first time. Thanks to Alexandre Ferrieux
-	<ferrieux@users.sourceforge.net> for report and patch.
-
-2008-04-02  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclIO.c (CopyData): Applied patch for the fcopy problem
-	[Bug 780533], with many thanks to Alexandre Ferrieux
-	<ferrieux@users.sourceforge.net> for tracking it down and
-	providing a solution. Still have to convert his test script into a
-	proper test case.

-2008-04-01  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclStrToD.c: Applied patch for [Bug 1839067] (fp

-2008-04-01  Don Porter	<dgp@users.sourceforge.net>
-

-
-2008-03-30  Kevin Kenny  <kennykb@acm.org>
-
-	* generic/tclInt.h (TclIsNaN):
-	* unix/configure.in: Added code to the configurator to check for
-	                     a standard isnan() macro and use it if one
-	                     is found.  This change avoids bugs where
-	                     the test of ((d) != (d)) is optimized away
-			     by an overaggressive compiler. [Bug 1783544]
-	* generic/tclObj.c: Added missing #include <math.h> needed to
-			    locate isnan() after the above change.
-
-	* unix/configure: autoconf-2.61
-
-	* tests/mathop.test (mathop-25.9, mathop-25.14): Modified tests
-	to deal with (slightly buggy) math libraries in which pow()
-	returns an incorrectly rounded result. [Bug 1808174]

-
-2008-03-20  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tcl.h, generic/tclThreadAlloc.c: Tidied up the declarations
-	of Tcl_GetMemoryInfo so that it is always defined. Will panic when
-	called against a Tcl that was previously built without it at all,
-	which is OK because that also indicates a serious mismatch between

-
-2008-03-19  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tcl.h, generic/tclThreadAlloc.c (Tcl_GetMemoryInfo): Make

-
-2008-03-18  Andreas Kupries  <andreask@activestate.com>
-
-	* library/tm.tcl (::tcl::tm::UnknownHandler): Changed 'source' to
-	'source -encoding utf-8'. This fixes a portability problem of Tcl
-	Modules pointed out by Don Porter. By using plain 'source' we were at
-	the mercy of 'encoding system', making modules less portable than they
-	could be. The exact scenario: A writes a TM in some weird encoding
-	which is A's system encoding, distributes it, and somewhere else it
-	cannot be read/used because the system encoding is different. Forcing
-	the use of utf-8 makes the module portable.
-
-	***INCOMPATIBILITY*** for all Tcl Modules already written in non-utf-8
-	compatible encodings.

-2008-03-18  Don Porter	<dgp@users.sourceforge.net>

-
-2008-03-18  Andreas Kupries  <andreask@activestate.com>
-
-	* library/tm.tcl (::tcl::tm::Defaults): Modified handling of
-	environment variables. See [Bug 1914604]. Solution slightly different
-	than proposed in the report. Using the underscored form TCLX_y_TM_PATH
-	even if TCLX.y_TM_PATH exists. Also using a loop to cut prevent code
-	replication.
-
-2008-03-16  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tclCompCmds.c (TclCompileDictForCmd): Correct the handling
-	of stack space calculation (the jump pattern used was confusing the
-	simple-minded code doing the calculations). [Bug 1903325]
-
-	* doc/lreplace.n: Clarified documentation of what happens with
-	negative indices. [Bug 1905809] Added example, tidied up formatting.
-
-2008-03-14  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclBasic.c (OldMathFuncProc):	Same workaround protection
-	from bad TclStackAlloc() alignment. Thanks George Peter Staplin.
-
-	* generic/tclCmdIL.c (Tcl_LsortObjCmd):	Use ckalloc() to allocate
-	SortElement arrays instead of TclStackAlloc() which isn't getting
-	alignment right. Workaround for [Bug 1914503].
-
-2008-03-14  Reinhard Max  <max@suse.de>

-	[Bug 1893053]
-
-	* macosx/tclMacOSXNotify.c: Avoid using CoreFoundation after fork() on

-
-	* macosx/Tcl.xcodeproj/project.pbxproj:	Add support for Xcode 3.1 and
-	* macosx/Tcl.xcodeproj/default.pbxuser:	configs for building with

-	* tests/socket.test (socket-2.11):	(esp. on multi-proc machines).
-
-	* tests/fCmd.test (fCmd-9.4):		Skip on Darwin 9 (xfail).
-
-2008-03-11  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclVar.c (TclDeleteNamespaceVars):
-	* tests/var.test (var-8.2): Unset traces on vars should be called with
-	a FQ named during namespace deletion. This was causing infinite loops
-	when unset traces recreated the var, as reported by Julian Noble. [Bug
-	1911919]
-
-2008-03-10  Don Porter	<dgp@users.sourceforge.net>
-
-	* changes:		Updated for 8.5.2 release.
-
-	* doc/http.n:	Revised to indicate that [package require http 2.5.5]
-	is needed to get all the documented commands ([http::meta]).
-
-	* generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd):  Added error
-	* tests/event.test (event-5.*):	checking to protect against callers
-	passing invalid return options dictionaries. [Bug 1901113]
-
-	* generic/tclBasic.c (ExprAbsFunc):	Revised so that the abs()
-	* tests/expr.test:	function and the [::tcl::mathfunc::abs]
-	command do not return the value of -0, or equivalent values with more
-	alarming string reps like -1e-350. [Bug 1893815]
-
-2008-03-07  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclResult.c (ReleaseKeys): Workaround for [Bug 1904907].
-	Reset the return option keys to NULL to allow full re-initialization
-	by GetKeys(). This introduces a memory leak for the key objects, but
-	gets us around a crash in the finalization of reflected channels when
-	handling returns, either at compile- or runtime. In both cases we
-	access the keys after they have been released by their thread exit
-	handler. A proper fix is entangled with the untangling of the
-	finalization ordering and attendant issues. For now we choose the
-	lesser evil.
-
-2008-03-07  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclExecute.c (Tcl_ExprObj):	Revised expression bytecode
-	compiling so that bytecodes invalid due to changing context or due to
-	the difference between expressions and scripts are not reused. [Bug
-	1899164]
-
-	* generic/tclCmdAH.c:	Revised direct evaluation implementation of
-	[expr] so that [expr $e] caches compiled bytecodes for the expression
-	as the intrep of $e.
-
-	* tests/execute.test (execute-6.*):	More tests checking that
-	script bytecode is invalidated in the right situations.
-
-2008-03-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
-
-	* win/configure.in: Add AC_HEADER_STDC to support msys/win64.
-
-2008-03-06  Donal K. Fellows  <dkf@users.sf.net>
-
-	* doc/namespace.n: Minor tidying up. [Bug 1909019]

-
-	* unix/tclUnixChan.c: Fix mark and space parity on Linux, which uses
-	CMSPAR instead of PAREXT.
-
-2008-03-02  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclNamesp.c (GetNamespaceFromObj):
-	* tests/interp.test (interp-28.2): Spoil the intrep of an nsNameType
-	obj when the reference crosses interpreter boundaries.
-
-2008-02-29  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclResult.c (Tcl_SetReturnOptions):	Revised the refcount
-	management of Tcl_SetReturnOptions to become that of a conventional
-	Consumer routine.  Thanks to Peter Spjuth for pointing out the
-	difficulties calling Tcl_SetReturnOptions with non-0-count value for
-	options.
-	* generic/tclExecute.c (INST_RETURN_STK): Revised the one caller
-	within Tcl itself which passes a non-0-count value to
-	Tcl_SetReturnOptions().
-
-	* generic/tclBasic.c (Tcl_AppendObjToErrorInfo):	Revised the
-	refcount management of Tcl_AppendObjToErrorInfo to become that of a
-	conventional Consumer routine. This preserves the ease of use for the
-	overwhelming common callers who pass in a 0-count value, but makes the
-	proper call with a non-0-count value less surprising.
-	* generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd):	Revised the
-	one caller within Tcl itself which passes a non-0-count value to
-	Tcl_AppendObjToErrorInfo().
-
-2008-02-28  Joe English  <jenglish@users.sourceforge.net>
-
-	* unix/tclPort.h, unix/tclCompat.h, unix/tclUnixChan.h: Reduce scope

-	TclUnixSetBlockingMode() [Patch 1903339].
-
-2008-02-28  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclBasic.c (TclEvalObjvInternal):	Plug memory leak when
-	an enter trace deletes or changes the command, prompting a reparsing.
-	Don't let the second pass lose commandPtr value allocated during the
-	first pass.
-
-	* generic/tclCompExpr.c (ParseExpr):	Plug memory leak in error
-	message generation.
-
-	* generic/tclStringObj.c (Tcl_AppendFormatToObj): [format %llx $big]
-	leaked an mp_int.
-
-	* generic/tclCompCmds.c (TclCompileReturnCmd):	The 2007-10-18 commit
-	to optimize compiled [return -level 0 $x] [RFE 1794073] introduced a
-	memory leak of the return options dictionary. Fixing that.
-
-2008-02-27  Pat Thoyts  <patthoyts@users.sourceforge.net>
-
-	* library/http/http.tcl: [Bug 705956] - fix inverted logic when

-
-	* doc/clock.n: Corrected minor indentation gaffe in the penultimate
-	paragraph. [Bug 1898025]
-	* generic/tclClock.c (ParseClockFormatArgs): Changed to check that the
-	clock value is in the range of a 64-bit integer. [Bug 1862555]
-	* library/clock.tcl (::tcl::clock::format, ::tcl::clock::scan,
-	(::tcl::clock::add, ::tcl::clock::LocalizeFormat): Fixed bugs in
-	caching of localized strings that caused weird results when localized
-	date/time formats were used. [Bug 1902423]
-	* tests/clock.test (clock-61.*, clock-62.1): Regression tests for [Bug
-	1862555] and [Bug 1902423].
-
-2008-02-26  Joe English  <jenglish@users.sourceforge.net>
-
-	* generic/tclIOUtil.c, unix/tclUnixPort.h, unix/tclUnixChan.c:
-	Remove dead/unused portability-related #defines and unused conditional
-	code.  See [Patch 1901828] for discussion.
-
-2008-02-26  Joe English  <jenglish@users.sourceforge.net>
-

-
-	* library/http/pkgIndex.tcl: Set version 2.5.5
-	* library/http/http.tcl:     It is better to do the [eof] check after

-2008-02-22  Pat Thoyts  <patthoyts@users.sourceforge.net>
-
-	* library/http/pkgIndex.tcl: Set version 2.5.4

-	* library/clock.tcl (::tcl::clock::format):
-	* tests/clock.test (clock-1.0, clock-1.4):
-	Performance enhancements in [clock format] (moving the analysis of

-2007-12-26  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclCmdIL.c: More [lsort] data handling streamlines. The
-	function MergeSort is gone, essentially inlined into Tcl_LsortObjCmd.
-	It is not a straight inlining, two loops over all lists elements where

-	merged into the temporary sublists in the same pass.
-
-2007-12-25  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclCmdIL.c: More [lsort] data handling streamlines. Extra

-
-	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Preallocate a listObj of
-	sufficient length for the sorted list instead of growing it. Second
-	commit replaces calls to Tcl_ListObjAppenElement with direct access to
-	the internal rep.

-
-
-	* generic/tclBasic.c (Tcl_CreateInterp): Simplify the setting up of

-	* generic/tclCompCmds.c (TclCompileSwitchCmd): Adjusted the [switch]
-	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd):       command so that when
-	passed two arguments, no check for options are performed. This is OK
-	since in the two-arg case, detecting an option would definitely lead
-	to a syntax error. [Patch 1836519]
-
-2007-11-29  Jeff Hobbs  <jeffh@ActiveState.com>
-

-
-	* generic/tclCompCmds.c (TclCompileDictAppendCmd): Fix bug in [dict
-	append] compiler which caused strange stack corruption. [Bug 1837392]
-
-2007-11-23  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclIORChan.c: Fixed a problem with reflected channels. 'chan
-	postevent' is defined to work only from within the interpreter
-	containing the handler command. Sensible, we want only handler
-	commands to use it. It identifies the channel by handle. The channel
-	moves to a different interpreter or thread. The interpreter containing
-	the handler command doesn't know the channel any longer. 'chan
-	postevent' fails, not finding the channel any longer. Uhm.
-
-	Fixed by creating a second per-interpreter channel table, just for
-	reflected channels, where each interpreter remembers for which
-	reflected channels it has the handler command. This info does not move
-	with the channel itself. The table is updated by 'chan create', and
-	used by 'chan postevent'.
-
-	* tests/ioCmd.test: Updated the testsuite.
-
-2007-11-23  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* generic/tclVar.c (Tcl_ArrayObjCmd): handle the right data for
-	* tests/var.test (var-14.2):          [array names $var -glob $ptn]
-
-2007-11-23  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

-
-2007-11-22  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tclDictObj.c (Dict*Cmd,TclInitDictCmd): Rebuilt the [dict]

-
-2007-11-22  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
-
-	* generic/tclCmdMZ.c (Tcl_StringObjCmd): Rewrote the [string] and
-	* generic/tclDictObj.c (Tcl_DictObjCmd): [dict] implementations to be
-	ready for conversion to ensembles.
-
-	* tests/string.test (string-12.22): Flag shimmering bug found in
-	[string range].
-
-2007-11-21  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tclCompCmds.c (TclCompileEnsemble): Rewrote the ensemble
-	compiler to remove many of the limitations. Can now compile scripts
-	that use unique prefixes of subcommands, and which have mappings of a
-	command to multiple words (provided the first is a compilable command
-	of course).
-
-2007-11-21  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
-
-	* generic/tclNamesp.c (TclMakeEnsemble): Factor out the code to set up
-	a core ensemble from a table of information about subcommands, ready
-	for reuse within the core.
-
-	* generic/various: Start to return more useful Error codes, currently
-	mainly on assorted lookup failures.
-
-2007-11-20  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tclDictObj.c: Changed the underlying implementation of the
-	hash table used in dictionaries to additionally keep all entries in
-	the hash table in a linked list, which is only ever added to at the
-	end. This makes iteration over all entries in the dictionary in
-	key insertion order a trivial operation, and so cleans up a great deal
-	of complexity relating to dictionary representation and stability of
-	iteration order.
-
-	***POTENTIAL INCOMPATIBILITY***
-	For any code that depended on the (strange) old iteration order.
-
-	* generic/tclConfig.c (QueryConfigObjCmd): Correct usage of
-	Tcl_WrongNumArgs.

-2007-11-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
-
-	* generic/tclCmdIL.c (TclInitInfoCmd): Rename the implementation
-	commands for [info] to be something more "expected".
-
-	* generic/tclCompCmds.c (TclCompileInfoExistsCmd): Compiler for the

-	(TclCompileEnsemble): Cleaned up version of ensemble compiler that was
-	in TclCompileInfoCmd, but which is now much more generally applicable.
-
-	* generic/tclInt.h (ENSEMBLE_COMPILE): Added flag to allow for cleaner
-	turning on and off of ensemble bytecode compilation.
-
-	* generic/tclCompile.c (TclCompileScript): Add the cmdPtr to the list
-	of arguments passed to command compilers.

-
-	* generic/tclNamesp.c (NamespaceEnsembleCmd): Must pass a non-NULL
-	interp to Tcl_SetEnsemble* functions.
-
-	* doc/re_syntax.n: Try to make this easier to read. It's still a very
-	difficult manual page!
-
-	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Allow people to turn off the -rpath
-	option to their linker if they so desire. This is a configuration only
-	recommended for (some) vendors. Relates to [Patch 1231022].
-
-2007-11-15  Pat Thoyts  <patthoyts@users.sourceforge.net>
-
-	* win/tclWin32Dll.c: Prefer UINT_PTR to DWORD_PTR when casting pointers

-
-	* generic/tclNamesp.c (Tcl_SetEnsembleSubcommandList)
-	(Tcl_SetEnsembleMappingDict):		Special code to make sure that

-
-2007-11-14  Andreas Kupries  <andreask@activestate.com>

-
-2007-11-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
-
-	* generic/regc*.c: Eliminate multi-char collating element code

-	full code, it will remain on the 8.4 branch. [Bug 1831425]
-
-2007-11-13  Jeff Hobbs  <jeffh@ActiveState.com>

-	Cuts the memory consumption of the RE compiler. [Bug 1831425]
-
-2007-11-13  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tclCompCmds.c (TclCompileSwitchCmd, TclCompileRegexpCmd):
-	Extend [switch] compiler to handle regular expressions as long as
-	things are not too complex. Fix [regexp] compiler so that non-trivial
-	literal regexps get fed to INST_REGEXP.
-
-	* doc/mathop.n: Clarify definitions of some operations.
-
-2007-11-13  Miguel Sofer  <msofer@users.sf.net>
-
-	* unix/tclUnixInit.c: the TCL_NO_STACK_CHECK was being incorrectly
-	undefined here; this should be set (or not) in the compile options, it
-	is used elsewhere and needs to be consistent.
-
-2007-11-13  Pat Thoyts  <patthoyts@users.sourceforge.net>

-
-2007-11-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
-
-	* unix/tclUnixCompat.c (TclpGetHostByName): The six-argument form of

-
-2007-11-13  Don Porter	<dgp@users.sourceforge.net>
-

-
-2007-11-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
-
-	* unix/tclUnixChan.c (CreateSocketAddress): Rewrote to use the
-	thread-safe version of gethostbyname() by forward-porting the code used
-	in 8.4, and added rudimentary support for getaddrinfo() (not enabled by
-	default, as no autoconf-ery written). Part of fix for [Bug 1618235].
-
-2007-11-12  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* generic/tclGet.c (Tcl_Get, Tcl_GetInt): revert use of TclGet* macros
-	due to compiler warning. These cases won't save time either.
-
-	* generic/tclUtil.c (TclReToGlob): add more comments, set interp result
-	if specified on error.
-
-2007-11-12  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclBasic.c:		New macro TclResetResult, new iPtr flag
-	* generic/tclExecute.c:		bit INTERP_RESULT_UNCLEAN: shortcut for

-	* generic/tclStubLib.c:		[Patch 1830184]
-	* generic/tclUtil.c:

-
-	* generic/tclResult.c (ResetObjResult): clarify the logic.
-
-	* generic/tclBasic.c:		Increased usage of macros to detect

-	* win/tclWin32Dll.c: Restore simpler behaviour for stack checking, not

-	that "nobody does that", and so it is not worth the cost. Improved
-	failure comments (mistachkin).
-
-2007-11-10  Kevin Kenny  <kennykb@acm.org>
-
-	* win/tclWin32Dll.c: Rewrote the Windows stack checking algorithm to
-	use information from VirtualQuery to determine the bound of the stack.
-	This change fixes a bug where the guard page of the stack was never
-	restored after an overflow. It also eliminates a nasty piece of
-	assembly code for structured exception handling on mingw. It introduces
-	an assumption that the stack is a single memory arena returned from
-	VirtualAlloc, but the code in MSVCRT makes the same assumption, so it
-	should be fairly safe.

-	Port to windows - could be more efficient, but is already cheaper than

-2007-11-06  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclEncoding.c: Version of the embedded iso8859-1 encoding
-	handler that is faster (functions to do the encoding know exactly what
-	they're doing instead of pulling it from a table, though the table
-	itself has to be retained for use by shift encodings that depend on
-	iso8859-1). [Patch 1826906], committing for dkf.
-
-2007-11-05  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclConfig.c (Tcl_RegisterConfig): Modified to not extend the
-	config database if the encoding provided by the user is not found
-	(venc == NULL). Scripts expecting the data will error out, however we
-	neither crash nor provide bogus information. See [Bug 983509] for more
-	discussion.
-
-	* unix/tclUnixChan.c (TtyGetOptionProc): Accepted [Patch 1823576]

-
-2007-10-28  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tclEncoding.c (TclInitEncodingSubsystem): Hard code the
-	iso8859-1 encoding, as it's needed for more than just text (especially
-	binary encodings...) Note that other encodings rely on the encoding
-	being a table encoding (!) so we can't use more efficient encoding

-2007-09-12  Pat Thoyts	<patthoyts@users.sourceforge.net>
-
-	* win/makefile.vc, win/rules.vc, win/nmakehlp.c: Use nmakehlp to

-2007-09-11  Don Porter	<dgp@users.sourceforge.net>
-
-	* library/tcltest/tcltest.tcl:	Accept underscores and colons in

-
-2007-09-10  Jeff Hobbs	<jeffh@ActiveState.com>

-
-	* doc/package.n:	Restored the document parallel syntax of the

-
-2007-09-09  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclInt.h:	Removed the "nsName" Tcl_ObjType from the
-	* generic/tclNamesp.c:	registered set. Revised the management of the
-	* generic/tclObj.c:	intrep of that Tcl_ObjType. Revised the
-	* tests/obj.test:	TclGetNamespaceFromObj() routine to return
-	TCL_ERROR and write a consistent error message when a namespace is not
-	found. [Bug 1588842. Patch 1686862]
-
-	***POTENTIAL INCOMPATIBILITY***
-	For callers of Tcl_GetObjType() on the name "nsName".
-
-	* generic/tclExecute.c: Update TclGetNamespaceFromObj() callers.
-	* generic/tclProc.c:
-
-	* tests/apply.test:		Updated tests to expect new consistent
-	* tests/namespace-old.test:	error message when a namespace is not
-	* tests/namespace.test:		found.
-	* tests/upvar.test:
-
-	* generic/tclCompCmds.c:	Use the new INST_REVERSE instruction
-	* tests/mathop.test:	to correct the compiled versions of math
-	operator commands. [Bug 1724437]
-
-	* generic/tclCompile.c: New bytecode instruction INST_REVERSE to
-	* generic/tclCompile.h: reverse the order of N items at the top of
-	* generic/tclExecute.c: stack.
-
-	* generic/tclCompCmds.c (TclCompilePowOpCmd):	Make a separate
-	routine to compile ** to account for its different associativity.
-
-2007-09-08  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclVar.c (Tcl_SetVar2, TclPtrSetVar): [Bug 1710710] fixed

-
-2007-09-08  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tclDictObj.c (DictUpdateCmd, DictWithCmd): Plug a hole that
-	* generic/tclExecute.c (TEBC,INST_DICT_UPDATE_END): allowed a careful
-	* tests/dict.test (dict-21.16,21.17,22.11): attacker to craft a dict
-	containing a recursive link to itself, violating one of Tcl's
-	fundamental datatype assumptions and causing a stack crash when the
-	dict was converted to a string. [Bug 1786481]
-
-2007-09-07  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclEvent.c ([::tcl::Bgerror]):	Corrections to Tcl's
-	* tests/event.test:	default [interp bgerror] handler so that when
-	it falls back to a hidden [bgerror] in a safe interp, it gets the
-	right error context data. [Bug 1790274]
-
-2007-09-07  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclProc.c (TclInitCompiledLocals): the refCount of resolved
-	variables was being managed without checking if they were Var or
-	VarInHash: itcl [Bug 1790184]
-
-2007-09-06  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclResult.c (Tcl_GetReturnOptions):	Take care that a
-	* tests/init.test:	non-TCL_ERROR code doesn't cause existing
-	-errorinfo, -errorcode, and -errorline entries to be omitted.
-	* generic/tclEvent.c:	With -errorInfo no longer lost, generate more
-	complete ::errorInfo when calling [bgerror] after a non-TCL_ERROR
-	background exception.
-
-2007-09-06  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclInterp.c (Tcl_Init):	Removed constraint on ability
-	to define a custom [tclInit] before calling Tcl_Init(). Until now the
-	custom command had to be a proc. Now it can be any command.
-
-	* generic/tclInt.decls: New internal routine TclBackgroundException()
-	* generic/tclEvent.c:	that for the first time permits non-TCL_ERROR
-	exceptions to trigger [interp bgerror] handling. Closes a gap in TIP
-	221. When falling back to [bgerror] (which is designed only to handle
-	TCL_ERROR), convert exceptions into errors complaining about the
-	exception.
-
-	* generic/tclInterp.c:	Convert Tcl_BackgroundError() callers to call
-	* generic/tclIO.c:	TclBackgroundException().
-	* generic/tclIOCmd.c:
-	* generic/tclTimer.c:
-
-	* generic/tclIntDecls.h:	make genstubs
-	* generic/tclStubInit.c:

-
-	* macosx/Tcl.xcode/project.pbxproj: discontinue unmaintained support
-	* macosx/Tcl.xcode/default.pbxuser: for Xcode 1.5; replace by Xcode2
-	project for use on Tiger (with Tcl.xcodeproj to be used on Leopard).
-
-	* macosx/Tcl.xcodeproj/project.pbxproj: updates for Xcode 2.5 and 3.0.
-	* macosx/Tcl.xcodeproj/default.pbxuser:
-	* macosx/Tcl.xcode/project.pbxproj:
-	* macosx/Tcl.xcode/default.pbxuser:

-2007-09-05  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclBasic.c:	Removed support for the unmaintained
-	* generic/tclExecute.c: -DTCL_GENERIC_ONLY configuration. [Bug
-	* unix/Makefile.in:	1264623]
-
-2007-09-04  Don Porter	<dgp@users.sourceforge.net>
-
-	* unix/Makefile.in:	It's unreliable to count on the release
-	manager to remember to `make genstubs` before `make dist`. Let the
-	Makefile remember the dependency for us.
-
-	* unix/Makefile.in:	Corrections to `make dist` dependencies to be
-	sure that macosx/configure gets generated whenever it does not exist.

-	caused this call to return an empty object rather than an error.
-
-2007-09-03  Daniel Steffen  <das@users.sourceforge.net>
-
-	* generic/tclObj.c (TclInitObjSubsystem): restore registration of the

-	tclWideIntType.
-
-2007-09-02  Donal K. Fellows  <dkf@users.sf.net>

-
-2007-08-30  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompile.c: Added fflush() calls following all callers of

-	with other code.
-
-2007-08-28  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompExpr.c:	Use a table lookup in ParseLexeme() to

-
-	* generic/tclBasic.c:	Used unions to better clarify overloading of
-	* generic/tclCompExpr.c:	the fields of the OpCmdInfo and
-	* generic/tclCompile.h:		TclOpCmdClientData structs.
-
-2007-08-27  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompExpr.c:	Call TclCompileSyntaxError() when
-	expression syntax errors are found when compiling expressions. With
-	this in place, convert TclCompileExpr to return void, since there's no
-	longer any need to report TCL_ERROR.
-	* generic/tclCompile.c: Update callers.
-	* generic/tclExecute.c:
-
-	* generic/tclCompCmds.c:	New routine TclCompileSyntaxError()
-	* generic/tclCompile.h: to directly compile bytecodes that report a
-	* generic/tclCompile.c: syntax error, rather than (ab)use a call to
-	TclCompileReturnCmd. Also, undo the most recent commit that papered
-	over some issues with that (ab)use. New routine produces a new opcode
-	INST_SYNTAX, which is a minor variation of INST_RETURN_IMM. Also a bit
-	of constification.
-
-	* generic/tclCompile.c: Move the deallocation of local LiteralTable
-	* generic/tclCompExpr.c:	entries into TclFreeCompileEnv().
-	* generic/tclExecute.c: Update callers.
-
-	* generic/tclCompExpr.c:	Force numeric and boolean literals in

-	overwriting existing intreps in already registered literals.
-
-2007-08-25  Kevin B. Kenny  <kennykb@acm.org>
-
-	* generic/tclExecute.c (TclExecuteByteCode): Added code to handle
-	* tests/expr.test (expr-23.48-53)	     integer exponentiation
-	that results in 32- and 64-bit integer results, avoiding calls to wide
-	integer exponentiation routines in this common case. [Bug 1767293]
-
-	* library/clock.tcl (ParseClockScanFormat): Modified code to allow

-	to handle callers other than TclCompileScript() failing to meet the
-	initialization assumptions of the TIP 280 code in CompileWord().
-
-	* generic/tclCompExpr.c:	Suppress the attempt to convert to
-	numeric when pre-compiling a constant expresion indicates an error.

-
-2007-08-20  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclExecute.c (INST_SUB): fix usage of the new macro for

-	added.
-
-2007-08-19  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tclExecute.c (Overflowing, TclIncrObj, TclExecuteByteCode):
-	Encapsulate Miguel's last change in a more mnemonic macro.
-
-2007-08-19  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclExecute.c: changed the check for overflow in sums,
-	reducing objsize, number of branches and cache misses (according to
-	cachegrind). Non-overflow for s=a+b:
-	previous
-	  ((a >= 0 || b >= 0 || s < 0) && (s >= 0 || b < 0 || a < 0))
-	now
-	  (((a^s) >= 0) || ((a^b) < 0))

-	different sign".

-2007-08-16  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclVar.c: improved localVarNameType caching to leverage
-	the new availability of Tcl_Obj in variable names, avoiding string
-	comparisons to verify that the cached value is usable.
-
-	* generic/tclExecute.c: check the two most frequent instructions

-2007-08-16  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompExpr.c:	Added a "constant" field to the OpNode
-	struct (again "free" due to alignment requirements) to mark those
-	subexpressions that are completely known at compile time. Enhanced
-	CompileExprTree() and its callers to precompute these constant
-	subexpressions at compile time. This resolves the issue raised in [Bug
-	1564517].

-
-	* generic/tclCompExpr.c:	Revise CompileExprTree() to use the

-	to use magic values in the left and right fields for that purpose.
-	Also stop abusing the left field within ParseExpr() to store the

-
-	* tests/parseExpr.test: Update source file name of expr parser code.
-
-	* generic/tclCompExpr.c:	Added a "mark" field to the OpNode
-	struct, which is used to guide tree traversal. This field costs
-	nothing since alignement requirements used the memory already.
-	Rewrote ConvertTreeToTokens() to use the new field, which permitted

-
-	*** POTENTIAL INCOMPATIBILITY *** (tclInt.h and tclCompile.h)
-	Extensions that access internals defined in tclInt.h and/or
-	tclCompile.h may lose both binary and source compatibility. The
-	relevant changes are:
-	1. 'struct Var' is completely changed, all acceses to its internals
-	   (either direct or via the TclSetVar* and TclIsVar* macros) will
-	   malfunction. Var flag values and semantics changed too.
-	2. 'struct Bytecode' has an additional field that has to be
-	   initialised to NULL
-	3. 'struct Namespace' is larger, as the varTable is now one pointer
-	   larger than a Tcl_HashTable. Direct access to its fields will
-	   malfunction.
-	4. 'struct CallFrame' grew one more field (the second such growth with
-	   respect to Tcl8.4).
-	5. API change for the functions TclFindCompiledLocal, TclDeleteVars
-	   and many internal functions in tclVar.c
-
-	Additionally, direct access to variable hash tables via the standard
-	Tcl_Hash* interface is to be considered as deprecated. It still works
-	in the present version, but will be broken by further specialisation
-	of these hash tables. This concerns especially the table of array
-	elements in an array, as well as the varTable field in the Namespace
-	struct.

-	* generic/tclExecute.c (TEBC, TclGetSrcInfoForCmd):
-	* generic/tclInt.h:
-	* generic/tclTrace.c (TclCheck(Interp|Execution)Traces):
-	Removed the need for TEBC to inspect the command before calling TEOvI,

-	into TEOvI/GetCommandSource.

-2007-07-20  Andreas Kupries  <andreask@activestate.com>
-
-	* library/platform/platform.tcl: Fixed bug in 'platform::patterns'
-	* library/platform/pkgIndex.tcl: where identifiers not matching
-	* unix/Makefile.in: the special linux and solaris forms would not
-	* win/Makefile.in: get 'tcl' as an acceptable platform added to
-	* doc/platform.n: the result. Bumped package to version 1.0.3 and
-	* doc/platform_shell.n: updated documentation and Makefiles. Also
-	fixed bad version info in the documentation of platform::shell.
-
-2007-07-19  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclParse.c:	In contexts where interp and parsePtr->interp
-	might be different, be sure to use the latter for error reporting.
-	Also pulled the interp argument back out of ParseTokens() since we
-	already had a parsePtr->interp to work with.
-
-2007-07-18  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompExpr.c:	Removed unused arguments and variables
-
-2007-07-17  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompExpr.c (ParseExpr):	While adding comments to
-	explain the operations of ParseExpr(), made significant revisions to
-	the code so it would be easier to explain, and in the process made the
-	code simpler and clearer as well.
-
-2007-07-15  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompExpr.c:	More commentary.
-	* tests/parseExpr.test:		Several tests of syntax error messages

-	visible the context relevant to the reported error.
-
-2007-07-12  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompExpr.c:	Factored out, corrected, and commented

-
-	* generic/tclCompCmds.c (TclCompileWhileCmd):
-	* generic/tclCompile.c (TclCompileScript):
-	Corrected faulty avoidance of INST_START_CMD when the first opcode in
-	a script is within a loop (as produced by 'while 1'), so that the
-	corresponding command is properly counted. [Bug 1752146]
-
-2007-07-11  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompExpr.c:	Added a "parseOnly" flag argument to
-	ParseExpr() to indicate whether the caller is Tcl_ParseExpr(), with an
-	end goal of filling a Tcl_Parse with Tcl_Tokens representing the
-	parsed expression, or TclCompileExpr() with the goal of compiling and
-	executing the expression. In the latter case, more aggressive
-	conversion of QUOTED and BRACED lexeme to literals is done. In the
-	former case, all such conversion is avoided, since Tcl_Token
-	production would revert it anyway. This enables simplifications to the
-	GenerateTokensForLiteral() routine as well.
-
-2007-07-10  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompExpr.c:	Added a field for operator precedence
-	to be stored directly in the parse tree. There's no memory cost to
-	this addition, since that memory would have been lost to alignment
-	issues anyway. Also, converted precedence definitions and lookup
-	tables to use symbolic constants instead of raw number for improved
-	readability, and continued extending/improving/correcting comments.
-	Removed some unused counter variables. Renamed some variables for
-	clarity and replaced some cryptic logic with more readable macros.
-
-2007-07-09  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompExpr.c:	Revision so that the END lexeme never
-	gets inserted into the parse tree. Later tree traversal never reaches
-	it since its location in the tree is not variable. Starting and
-	stopping with the START lexeme (node 0) is sufficient. Also finished
-	lexeme code commentary.
-
-	* generic/tclCompExpr.c:	Added missing creation and return of
-	the Tcl_Parse fields that indicate error conditions. [Bug 1749987]
-
-2007-07-05  Don Porter	<dgp@users.sourceforge.net>
-

-
-2007-07-03  Don Porter	<dgp@users.sourceforge.net>
-

-	is now more expansion room to define more BINARY operators.
-
-2007-07-02  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tclHash.c (CompareStringKeys): Always use the strcmp()
-	version; the operation is functionally equivalent, the speed is
-	identical (up to measurement limitations), and yet the code is
-	simpler. [FRQ 951168]
-
-2007-07-02  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tcl.h:	Removed TCL_PRESERVE_BINARY_COMPATIBILITY and
-	* generic/tclHash.c:	any code enabled when it is set to 0. We will
-	* generic/tclStubInit.c:	always want to preserve binary compat
-	of the structs that appear in the interface through the 8.* series of
-	releases, so it's pointless to drag around this never-enabled
-	alternative.
-
-	* generic/tclIO.c:	Removed dead code.
-	* unix/tclUnixChan.c:
-
-	* generic/tclCompExpr.c:	Removed dead code, old implementations
-	* generic/tclEvent.c:	of expr parsing and compiling, including the

-
-2007-06-29  Donal K. Fellows  <dkf@users.sf.net>

-
-2007-06-29  Daniel Steffen  <das@users.sourceforge.net>
-
-	* generic/tclAlloc.c:		on Darwin, ensure memory allocated by

-
-	* generic/tclGetDate.y: use ckalloc/ckfree instead of malloc/free.

-
-2007-06-24  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclVar.c (TclDeleteCompiledLocalVars): removed inlining that
-	ended up not really optimising (limited benchmarks). Now calling
-	UnsetVarStruct (streamlined old code is #ifdef'ed out, in case better
-	benchmarks do show a difference).
-
-	* generic/tclVar.c (UnsetVarStruct): fixed a leak introduced in last
-	commit.
-
-2007-06-23  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclVar.c (UnsetVarStruct, TclDeleteVars): made the logic

-
-	*** POTENTIAL INCOMPATIBILITY *** (tclInt.h and Var struct users)
-	The core never builds VAR_LINK variable to have traces. Such a

-	easier for callers to use (or more precisely, harder to misuse).
-	TclStackFree now takes a (void *) argument which is the pointer

-

-
-	* generic/tclExecute.c:	 comments added to explain iPtr->numLevels

-
-	* generic/tclNamesp.c:	 tweaks to Tcl_GetCommandFromObj and

-	is NULL for fully qualified names.
-
-2007-06-10  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclBasic.c:	 Further TEOvI split, creating a new
-	* generic/tclCompile.h:	 TclEvalObjvKnownCommand() function to handle
-	* generic/tclExecute.c:	 commands that are already known and are not
-	traced. INST_INVOKE now calls into this function instead of inlining
-	parts of TEOvI. Same perf, better isolation.
-
-	***POTENTIAL INCOMPAT*** There is a subtle issue with the timing of
-	execution traces that is changed here - first change appeared in my
-	commit of 2007-04-03 [Patch 1693802], which caused some divergence

-	faster too.
-
-2007-06-09  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclExecute.c (INST_INVOKE): isolated two vars to the small
-	block where they are actually used.
-
-	* generic/tclObj.c (Tcl_GetCommandFromObj): rewritten to make the
-	logic clearer; slightly faster too.
-
-	* generic/tclBasic.c:	Split TEOv in two, by separating a processor
-	for non-TCL_OK returns. Also split TEOvI in a full version that
-	handles non-existing and traced commands, and a separate shorter
-	version for the regular case.
-
-	* generic/tclBasic.c:	Moved the generation of command strings for
-	* generic/tclTrace.c:	traces: previously in Tcl_EvalObjv(), now in
-	TclCheck[Interp|Execution]Traces(). Also insured that the strings are
-	properly NUL terminated at the correct length. [Bug 1693986]
-
-	***POTENTIAL INCOMPATIBILITY in internal API***
-	The functions TclCheckInterpTraces() and TclCheckExecutionTraces() (in
-	internal stubs) used to be noops if the command string was NULL, this
-	is not true anymore: if the command string is NULL, they generate an
-	appropriate string from (objc,objv) and use it to call the traces. The
-	caller might as well not call them with a NULL string if he was
-	expecting a noop.
-
-	* generic/tclBasic.c:	Extend usage of TclLimitReady() and
-	* generic/tclExecute.c: (new) TclLimitExceeded() macros.
-	* generic/tclInt.h:

-
-	* generic/tclBasic.c:	Removed code that dealt with
-	* generic/tclCompile.c: TCL_TOKEN_EXPAND_WORD tokens representing
-	* generic/tclCompile.h: expanded literal words. These sections were
-	mostly in place to enable [info frame] to discover line information in
-	expanded literals. Since the parser now generates a token for each
-	post-expansion word referring to the right location in the original
-	script string, [info frame] gets all the data it needs.
-
-	* generic/tclInt.h:	Revised the parser so that it never produces
-	* generic/tclParse.c:	TCL_TOKEN_EXPAND_WORD tokens when parsing an
-	* tests/parse.test:	expanded literal word; that is, something like
-	{*}{x y z}. Instead, generate the series of TCL_TOKEN_SIMPLE_WORD

-	produces. [RFE 1725186]

-
-2007-04-22  Miguel Sofer  <msofer@users.sf.net>

-	* generic/tclPathObj.c: Corrected a 'const'ness fault that caused
-	bitter complaints from MSVC.
-	* tests/clock.test (clock-40.1, clock-58.1, clock-59.1): Corrected a

-	for military time zone input conversion. [Bug 1586828]

-	compiler.
-
-2007-04-18  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclExecute.c (INST_LSHIFT): fixed a mistake introduced in
-	version 1.266 ('=' became '=='), which effectively turned the block
-	that handles native shifts into dead code. This explains why the
-	testsuite did not pick this mistake. Rewrote to make the intention
-	clear.
-
-	* generic/tclInt.h (TclDecrRefCount): change the order of the
-	branches, use empty 'if ; else' to handle use in unbraced outer

-
-	* generic/tclInt.h (TclNewLiteralStringObj): New macro to make
-	allocating literal string objects (i.e. objects whose value is a
-	constant string) easier and more efficient, by allowing the omission
-	of the length argument. Based on [Patch 1529526] (afredd)
-	* generic/*.c: Make use of this (in many files).

-
-	* generic/tclCompile.c (TclCompileScript, TclPrintInstruction):
-	* generic/tclExecute.c (TclExecuteByteCode): Changed the definition of
-	INST_START_CMD so that it knows how many commands start at the current
-	location. This makes the interpreter command counter correct without
-	requiring a large number of instructions to be issued. (See my change
-	from 2007-01-19 for what triggered this.)
-
-2007-03-30  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompile.c:
-	* generic/tclCompExpr.c:
-	* generic/tclCompCmds.c:	Replace arrays on the C stack and

-	return path.
-
-2007-03-28  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCmdMZ.c (STR_REVERSE):	Implement the actual [string
-	reverse] command in terms of the new TclStringObjReverse() routine.
-
-	* generic/tclInt.h (TclStringObjReverse):	New internal routine
-	* generic/tclStringObj.c (TclStringObjReverse): that implements the
-	[string reverse] operation, making use of knowledge/surgery of the

-	the job.
-
-2007-03-27  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCmdMZ.c (STR_MAP): Replace ckalloc calls with
-	TclStackAlloc calls.
-
-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.
-
-2007-03-23  Miguel Sofer  <msofer@users.sf.net>
-

-
-2007-03-22  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCmdAH.c (Tcl_ForeachObjCmd):	Replaced arrays on the
-	C stack and ckalloc calls with TclStackAlloc calls to use memory on
-	Tcl's evaluation stack.
-
-	* generic/tclExecute.c: Revised GrowEvaluationStack to take an
-	argument specifying the growth required by the caller, so that a
-	single reallocation / copy is the most that will ever be needed even
-	when required growth is large.
-
-2007-03-21  Don Porter	<dgp@users.sourceforge.net>

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

-
-	* generic/tclEvent.c (HandleBgErrors):	Make efficient private copy

-
-	* generic/tclVar.c (TclArraySet):	Make efficient private copy of

-2007-03-09  Andreas Kupries  <andreask@activestate.com>
-
-	* library/platform/shell.tcl: Made more robust if an older platform
-	* library/platform/pkgIndex.tcl: package is present in the inspected
-	* unix/Makefile.in: shell. Package forget it to prevent errors. Bumped
-	* win/Makefile.in: package version to 1.1.3, and updated the Makefiles

-	code for version-2 'zoneinfo' files.
-	* tests/clock.test (clock-56.3): Added a test case for Y2038 and
-	'zoneinfo'. Modified test initialisation to use the
-	'loadTestedCommands' function of tcltest to bring in the correct path
-	for the registry library.
-
-2007-03-08  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclListObj.c (TclLsetList):	Rewrite so that the routine
-	itself does not do any direct intrep surgery. Better isolates those
-	things into the implementation of the "list" Tcl_ObjType.
-
-2007-03-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
-
-	* generic/tclListObj.c (TclLindexList, TclLindexFlat): Moved these

-
-2007-03-08  Kevin B. Kenny  <kennykb@acm.org>
-
-	* library/clock.tcl: Further tweaks to the Windows time zone table
-	(restoring missing Mexican time zones). Added rudimentary handling of
-	version-2 'zoneinfo' files. Update US DST rules so that zones such as
-	'EST5EDT' get the correct transition dates.
-	* tests/clock.test: Added rudimentary test cases for 'zoneinfo'
-	parsing. Adjusted several tests that depended on obsolete US DST
-	transition rules.

-	* generic/tclCmdIL.c (TclLindex*):	Rewrites to make efficient
-	private copies of the list and indexlist arguments, so we can operate
-	on the list elements directly with no fear of shimmering effects.
-	Replaces defensive coding schemes that are otherwise required. End
-	result is that TclLindexList is entirely a wrapper around
-	TclLindexFlat, which is now the core engine of all [lindex]
-	operations.
-
-	* generic/tclObj.c (Tcl_AppendAllObjTypes):	Converted to simpler
-	list validity test.
-
-2007-03-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

-
-	* generic/tclCompExpr.c:	Now that the new internal structs are

-	removed.
-
-	* generic/tclBasic.c:	Final step routing all direct evaluation forms

-
-	* generic/tclBasic.c:	 Another step down the path of re-using
-	* generic/tclCompExpr.c: TclExecuteByteCode to implement the TIP 174
-	* generic/tclCompile.h: commands instead of using a mass of code
-	* generic/tclMathOp.c:	duplication. Now all operator commands that

-
-	* generic/tclCompExpr.c: Revised implementation of TclInvertOpCmd to

-	This demonstrates a path toward avoiding mountains of code duplication
-	in tclMathOp.c and tclExecute.c.
-
-	* generic/tclCompile.h: Change TclExecuteByteCode() from static to

-2006-12-05  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclPkg.c:	When no requirements are supplied to a
-	* tests/pkg.test:	[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/tclCompExpr.c:	Added implementation for the

-	USE_EXPR_TOKENS to try it out.
-
-2006-12-03  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompExpr.c:	Added expr parsing routines that
-	produce a different set of internal structures representing the parsed

-	into the traditional Tcl_Token array format. Use of these routines is
-	currently disabled. #undef PARSE_DIRECT_EXPR_TOKENS to enable them.
-	These routines will only become really useful when more routines that
-	compile directly from the new internal structures are completed.

-	* generic/tclNamesp.c (EnsembleImplementationCmd):
-	* tests/namespace.test (47.7-8): reverted a wrong "optimisation" that
-	completely broke snit; added two tests.
-
-2006-10-28  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tclProc.c (ObjInterpProcEx, TclObjInterpProcCore): Split the
-	core of procedures to make it easier to build procedure-like code
-	without going through horrible contortions. This is the last critical
-	component to make advanced OO systems workable as simple loadable
-	extensions. TOIPC is now in the internal stub table.
-	(MakeProcError, MakeLambdaError): Refactored ProcessProcResultCode to
-	be simpler, some of which goes to TclObjInterpProcCore, and the rest
-	of which is now in these far simpler routines which just do errorInfo
-	stack generation for different types of procedure-like entity.
-	* tests/apply.test (apply-5.1): Updated to expect the more informative
-	form of message.
-
-2006-10-27  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tclVar.c (HasLocalVars): New macro to make various bits and
-	pieces cleaner.
-
-	* generic/tclNamesp.c (TclSetNsPath): Expose SetNsPath() through
-	internal stubs table with semi-external name.
-
-	* generic/tclInt.h (CallFrame): Add a field for handling context data
-	for extensions (like object systems) that should be tied to a call
-	frame (and not a command or interpreter).
-
-	* generic/tclBasic.c (TclRenameCommand): Change to take CONST args;
-	they were only ever used in a constant way anyway, so this appears to
-	be a spot that was missed during TIP#27 work.
-
-2006-10-26  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclProc.c (SetLambdaFromAny): minor change, eliminate
-	redundant call to Tcl_GetString (thanks aku).
-
-	* generic/tclInterp.c (ApplyObjCmd):
-	* generic/tclNamesp.c (EnsembleImplementationCmd): replaced ckalloc
-	(heap) with TclStackAlloc (execution stack).
-
-2006-10-24  Miguel Sofer  <msofer@users.sf.net>
-
-	* tests/info.test (info-9.11-12): tests for [Bug 1577492]
-	* tests/apply.test (apply-4.3-5): tests for [Bug 1574835]
-
-	* generic/tclProc.c (ObjInterpProcEx): disable itcl hacks for calls
-	from ApplyObjCmd (islambda==1), as they mess apply's error messages
-	[Bug 1583266]
-
-2006-10-23  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclProc.c (ApplyObjCmd): fix wrong#args for apply by using
-	the ensemble rewrite engine. [Bug 1574835]
-	* generic/tclInterp.c (AliasObjCmd): previous commit missed usage of
-	TCL_EVAL_NOREWRITE for aliases.
-
-	* generic/tclBasic.c (TclEvalObjvInternal): removed redundant check
-	for ensembles. [Bug 1577628]
-
-	* library/clock.tcl (format, scan): corrected wrong # args messages to
-	* tests/clock.test (3.1, 34.1):	    make use of the new rewrite
-	capabilities of [info level]
-
-	* generic/tcl.h:	   Lets TEOV update the iPtr->callObj[cv] new
-	* generic/tclBasic.c:	   fields, except when the flag bit
-	* generic/tclInt.h:	   TCL_EVAL_NOREWRITE is present. These values
-	* generic/tclNamesp.c:	   are used by Tcl_PushCallFrame to initialise
-	* generic/tclProc.c:	   the frame's obj[cv] fields, and allows
-	* tests/namespace.test:	   [info level] to know and use ensemble
-	rewrites. [Bug 1577492]
-
-	***POTENTIAL INCOMPATIBILITY***
-	The return value from [info level 0] on interp alias calls is changed:
-	previously returned the target command (including curried values), now
-	returns the source - what was actually called.
-
-2006-10-23  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tcl.h:	   Modified the Tcl call stack so there is
-	* generic/tclBasic.c:	   always a valid CallFrame, even at level 0
-	* generic/tclCmdIL.c:	   [Patch 1577278]. Most of the changes
-	* generic/tclInt.h:	   involve removing tests for a NULL
-	* generic/tclNamesp.c:	   iPtr->(var)framePtr. There is now a
-	* generic/tclObj.c:	   CallFrame pushed at interp creation with a
-	* generic/tclProc.c:	   pointer to it stored in iPtr->rootFramePtr.
-	* generic/tclTrace.c:	   A second unused field in Interp is
-	* generic/tclVar.c:	   hijacked to enable further functionality,
-	currently unused (but with several FRQs depending on it).
-
-	***POTENTIAL INCOMPATIBILITY***
-	Any user that includes tclInt.h and needs to determine if it is
-	running at level 0 should change (iPtr->varFramePtr == NULL) to
-	(iPtr->varFramePtr == iPtr->rootFramePtr).

-
-	* generic/tcl.h, generic/tclHash.c: Tcl_FindHashEntry now calls
-	Tcl_CreateHashEntry with a newPtr set to NULL: this would have caused
-	a segfault previously and eliminates duplicated code. A macro has been
-	added to tcl.h (only used when TCL_PRESERVE_BINARY_COMPATABALITY is
-	not set - i.e., not by default).
-

-
-2006-10-16  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclPkg.c (ExactRequirement):	Plugged memory leak. Also
-	changed Tcl_Alloc()/Tcl_Free() calls to ckalloc()/ckfree() for easier

-
-	* library/tcltest/tcltest.tcl:	Revise tcltest bump to 2.3a1.
-	* library/tcltest/pkgIndex.tcl: This permits more features to be
-	* unix/Makefile.in:	added to tcltest before we reach version 2.3.0
-	* win/Makefile.in:	best timed to match the release of Tcl 8.5.0.
-	* win/makefile.vc:	This also serves as a demo of TIP 268 features
-
-2006-10-13  Colin McCormack <coldstore@users.sf.net>
-

-	1576006]
-
-2006-10-12  David Gravereaux <davygrvy@pobox.com>
-

-
-2006-10-11  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclPkg.c (Tcl_PackageRequireEx):	Corrected crash when

-
-2006-10-10  Don Porter	<dgp@users.sourceforge.net>
-
-	* changes:	Updates for 8.5a5 release.
-
-	* generic/tclNamespace.c (TclTeardownNamespace):  After the
-	commandPathSourceList of a namespace is cleared, set the
-	commandPathSourceList to NULL so we don't try to walk the list a
-	second time, possibly after it is freed. [Bug 1566526]
-	* tests/namespace.test (namespace-51.16):	Added test.
-
-2006-10-09  Miguel Sofer  <msofer@users.sf.net>
-
-	* doc/UpVar.3: brough the docs in accordance to the code. Ever since
-	8.0, Tcl_UpVar(2)? accepts TCL_NAMESPACE_ONLY as a flag value, and
-	var-3.4 tests for proper behaviour. The docs only allowed 0 and
-	TCL_GLOBAL_ONLY. [Bug 1574099]
-
-2006-10-09  Miguel Sofer  <msofer@users.sf.net>
-
-	* tests/*.test: updated all tests to refer explicitly to the global
-	variables ::errorInfo, ::errorCode, ::env and ::tcl_platform: many
-	were relying on the alternative lookup in the global namespace, that
-	feature is tested specifically in namespace and variable tests.
-
-	The modified testfiles are: apply.test, basic.test, case.test,
-	cmdIL.test, cmdMZ.test, compExpr-old.test, error.test, eval.test,

-	1512138]
-
-	* generic/tclCompile.c:
-	* generic/tclHistory.c:

-
-2006-09-28  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclPkg.c (CompareVersions): Bugfix. Check string lengths
-	* tests/pkg.test: before comparison. The shorter string is the smaller
-	number. Added testcases as well. Interestingly all existing test cases
-	for vcompare compared numbers of the same length with each other. [Bug
-	1563836]
-
-2006-09-28  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclIO.c (Tcl_GetsObj): added two test'n'panic guards for
-	possible NULL derefs, [Bug 1566382] and coverity #33.
-
-2006-09-27  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclExecute.c: Corrected error in INST_LSHIFT in the
-	* tests/expr.test:	calculation done to determine whether a shift
-	in the (long int) type is possible. The calculation had literal value
-	"1" where it needed a value "1L" to compute the correct result. Error
-	detected via testing with the math::bigfloat package [Bug 1567222]
-
-	* generic/tclPkg.c (CompareVersion):	Flatten strcmp() results to
-	{-1, 0, 1} to match expectations of CompareVersion() callers.
-
-2006-09-27  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/regc_color.c (singleton):
-	* generic/regc_cvec.c (addmcce):
-	* generic/regcomp.c (compile, dovec): the static function addmcce does
-	nothing when called with two NULL pointers; the only call is by
-	compile with two NULL pointers (regcomp.c #includes regc_cvec.c).
-	Large parts (all?) the code for mcce (multi character collating
-	element) that we do not use is ifdef'ed out with the macro
-	REGEXP_MCCE_ENABLE.
-	This silences coverity bugs 7, 16, 80
-
-	* generic/regc_color.c (uncolorchain):
-	* generic/regc_nfa.c (freearc): changed tests and asserts to
-	equivalent formulation, designed to avoid an explicit comparison to
-	NULL and satisfy coverity that 6 and 9 are not bugs.
-
-2006-09-27  Andreas Kupries  <andreask@activestate.com>
-
-	* tests/pkg.test: Added test for version comparison at the 32bit
-	boundary. [Bug 1563836]
-
-	* generic/tclPkg.c: Rewrote CompareVersion to perform string
-	comparison instead of numeric. This breaks through the 32bit limit on
-	version numbers. See code for details (handling of leading zeros,
-	signs, etc.). un-CONSTed some arguments of CompareVersions,
-	RequirementSatisfied, and AllRequirementsSatisfied. The new compare
-	modifies the string (temporary string terminators). All callers use
-	heap-allocated ver-intreps, so we are good with that. [Bug 1563836]
-
-2006-09-27  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclFileName.c (TclGlob): added a panic for a call with
-	TCL_GLOBMODE_TAILS and pathPrefix==NULL. This would cause a segfault,
-	as found by coverity #26.
-
-2006-09-26  Kevin B. Kenny  <kennykb@acm.org>
-
-	* doc/Encoding.3:	 Added covariant 'const' qualifier for the
-	* generic/tcl.decls:	 Tcl_EncodingType argument to
-	* generic/tclEncoding.c: Tcl_CreateEncoding. [Further TIP#27 work.]
-	* generic/tclDecls.h:	 Reran 'make genstubs'.
-
-2006-09-26  Pat Thoyts	<patthoyts@users.sourceforge.net>
-
-	* win/makefile.vc:  Additional compiler flags and amd64 support.
-	* win/nmakehlp.c:
-	* win/rules.vc:
-
-2006-09-26  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tcl.h:	As 2006-09-22 commit from Donal K. Fellows
-	demonstrates, "#define NULL 0" is just wrong, and as a quotable chat
-	figure observed, "If NULL isn't defined, we're not using a C compiler"
-	Improper fallback definition of NULL removed.
-
-2006-09-25  Pat Thoyts	<patthoyts@users.sourceforge.net>
-
-	* generic/tcl.h:	More fixing which struct stat to refer to.
-	* generic/tclGetDate.y: Some casts from time_t to int required.
-	* generic/tclTimer.c:	Tcl_Time structure members are longs.
-	* win/makefile.vc:	Support for varying compiler options
-	* win/rules.vc:		and build to platform-specific subdirs.
-
-2006-09-25  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclIO.c (Tcl_StackChannel): Fixed [Bug 1564642], aka
-	coverity #51. Extended loop condition, added checking for NULL to
-	prevent seg.fault.
-
-2006-09-25  Andreas Kupries  <andreask@activestate.com>

-2006-09-25  Kevin B. Kenny  <kennykb@acm.org>
-
-	* generic/tclNotify.c (Tcl_DeleteEvents): Simplified the code in hopes
-	of making the invariants clearer and proving to Coverity that the
-	event queue memory is managed correctly.
-
-2006-09-25  Donal K. Fellows  <dkf@users.sf.net>
-
-	* generic/tclNotify.c (Tcl_DeleteEvents): Make it clear what happens

-
-2006-09-24  Miguel Sofer  <msofer@users.sf.net>
-
-	* generic/tclParse.c (Tcl_ParseCommand): also return an error if

-
-	* generic/tclStringObj.c (STRING_SIZE): fix allocation for 0-length
-	strings. This is coverity's bugs #54-5
-
-2006-09-22  Andreas Kupries  <andreask@activestate.com>
-
-	* generic/tclInt.h: Moved TIP#268's field 'packagePrefer' to the end

-
-2006-09-04  Jeff Hobbs	<jeffh@ActiveState.com>
-
-	* doc/package.n: correct package example
-
-2006-08-31  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclCompExpr.c:	Corrected flawed logic for disabling
-	the INST_TRY_CVT_TO_NUMERIC instruction at the end of an expression
-	when function arguments contain operators. [Bug 1541274]
-
-	* tests/expr-old.test:	The remaining failing tests reported in
-	* tests/expr.test:	[Bug 1381715] are all new in Tcl 8.5, so
-	there's really no issue of compatibility with Tcl 8.4 result to deal

-
-2006-08-29  Don Porter	<dgp@users.sourceforge.net>

-
-	* generic/tclFileName.c (DoGlob): match incrs with decrs.
-
-2006-08-29  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclParseExpr.c:	Use the "parent" field of orphan
-	ExprNodes to store the closure of left pointers. This lets us avoid
-	repeated re-scanning leftward for the left boundary of subexpressions,
-	which in worst case led to near O(N^2) runtime.
-
-2006-08-29  Joe Mistachkin  <joe@mistachkin.com>
-

-
-	* generic/tclStringObj.c:	Revised ObjPrintfVA to take care to
-	* generic/tclParseExpr.c:	copy only whole characters when doing
-	%s formatting. This relieves callers of TclObjPrintf() and
-	TclFormatToErrorInfo() from needing to fix arguments to character
-	boundaries. Tcl_ParseExpr() simplified by taking advantage. [Bug
-	1547786]
-
-	* generic/tclStringObj.c:	Corrected TclFormatObj's failure to

-2006-08-24  Kevin B. Kenny  <kennykb@acm.org>
-
-	* library/tzdata: Regenerated, including several new files, from
-	Olson's tzdata2006j.
-	* library/clock.tcl:
-	* tests/clock.test: Removed an early testing hack that allowed loading
-	'registry' from the build tree rather than an installed one. This is a
-	workaround for [Bug 15232730], which remains open because it's a
-	symptom of a deeper underlying problem.
-
-2006-08-23  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclParseExpr.c:	Minimal collection of new tests
-	* tests/parseExpr.test:		testing the error messages of the new

-	during that effort.
-
-2006-08-21  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclIOUtil.c:	Revisions to complete the thread finalization
-	of the cwdPathPtr. [Bug 1536142]
-

-	msys build is possible.
-
-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.
-
-	* 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]

-2006-08-18  Daniel Steffen  <das@users.sourceforge.net>
-
-	* unix/tcl.m4 (Darwin): add support for --enable-64bit on x86_64, for

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

-	* macosx/tclMacOSXFCmd.c:
-
-	* unix/tclUnixPort.h: on Darwin x86_64, disable use of vfork as it
-	causes execve to fail intermittently. (rdar://4685553)
-
-	* generic/tclTomMath.h: on Darwin 64-bit, for now disable use of
-	128-bit arithmetic through __attribute__ ((mode(TI))), as it leads to
-	link errors due to missing fallbacks. (rdar://4685527)
-

-
-	* macosx/Tcl.xcodeproj/default.pbxuser: add test suite target that

-	window.
-
-	* tests/macOSXFCmd.test: fix use of deprecated resource fork paths.
-
-	* unix/tclUnixInit.c (TclpInitLibraryPath): move code that is only
-	needed when TCL_LIBRARY is defined to run only in that case.
-
-	* generic/tclLink.c (LinkTraceProc): fix 64-bit signed-with-unsigned
-	comparison warning from gcc4 -Wextra.
-
-	* 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.

-
-	* tests/compExpr-old.test: add 'oldExprParser' constraint to all tests

-	* tests/compile.test:	   error messages of the pre-2006-07-05
-	* tests/expr-old.test:	   expression parser. The constraint is on by

-2006-07-31  Kevin B. Kenny  <kennykb@acm.org>
-
-	* generic/tclClock.c (ConvertLocalToUTCUsingC): Corrected a regression

-
-2006-07-30  Kevin B. Kenny  <kennykb@acm.org>
-
-	* generic/tclClock.c (GetJulianDayFromEraYearMonthDay): Corrected
-	several errors in converting dates before the Common Era [Bug 1426279]
-	* library/clock.tcl: Corrected syntax errors in generated code for %EC
-	%Ey, and %W format groups [Bug 1505383]. Corrected a bug in cache
-	management for format strings containing [glob] metacharacters [Bug
-	1494664]. Corrected several errors in formatting/scanning of years
-	prior to the Common Era, and added the missing %EE format group to
-	indicate the era.
-	* tools/makeTestCases.tcl: Added code to make sure that %U and %V
-	format groups are included in the tests. (The code depends on %U and
-	%V formatting working correctly when 'makeTestCases.tcl' is run,
-	rather than making a completely independent check.) Added tests for
-	[glob] metacharacters in strings. Added tests for years prior to the
-	Common Era.
-	* tests/clock.test: Rebuilt with new test cases for all the above.

-
-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/tclMacOSXFCmd.c (TclMacOSXCopyFileAttributes):	   add support
-	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier):		   for weakly
-	* unix/tclUnixInit.c (Tcl_GetEncodingNameFromEnvironment): importing

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

-	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; clean up
-	quoting and help messages.

-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.
-
-2006-07-05  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclParseExpr.c:	Completely new expression parser that
-	builds a parse tree instead of operating with deep recursion. This
-	corrects reports of stack-blowing crashes parsing long expressions
-	[Bug 906201] and replaces a fundamentally O(N^2) algorithm with an
-	O(N) one [RFE 903765]. The new parser is better able to generate error
-	messages that clearly report both the nature and context of the syntax
-	error [Bugs 1029267, 1381715]. For now, the code for the old parser is
-	still present and can be activated with a "#define OLD_EXPR_PARSER
-	1". This is for the sake of a clean implementation patch, and for ease
-	of benchmarking. The new parser is non-recursive, so much lighter in
-	stack consumption, but it does use more heap, so there may be cases
-	where parsing of long expressions that succeeded with the old parser
-	will lead to out of memory panics with the new one. There are still
-	more improvements possible on that point, though significant progress
-	may require changes to the Tcl_Token specifications documented for the
-	public Tcl_Parse*() routines.
-	***POTENTIAL INCOMPATIBILITY*** for any callers that rely on the exact
-	(usually terrible) error messages generated by the old parser. This
-	includes a large number of tests in the test suite.
-
-	* generic/tclInt.h:		Replaced TclParseWhiteSpace() with
-	* generic/tclParse.c:		TclParseAllWhiteSpace() which is what
-	* generic/tclParseExpr.c:	all the callers really needed.
-	Breaking whitespace runs at newlines is useful only to the command
-	parsing function, and it can call the file scoped routine
-	ParseWhiteSpace() to do that.
-
-	* tests/expr-old.test:	Removed knownBug constraints that masked
-	* tests/expr.test:	failures due to revised error messages.
-	* tests/parseExpr.test:
-
-2006-06-20  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclIOUtil.c:	Changed default configuration to
-	* generic/tclInt.decls: #undef USE_OBSOLETE_FS_HOOKS which disables
-	* generic/tclTest.c:	access to the Tcl 8.3 internal routines for
-	hooking into filesystem operations. Everyone ought to have migrated to
-	Tcl_Filesystems by now.
-	***POTENTIAL INCOMPATIBILITY*** for any code still stuck in the
-	pre-Tcl_Filesystem era.
-
-	* generic/tclIntDecls.h:	make genstubs
-	* generic/tclStubInit.c:
-
-	* generic/tclStrToD.c:	Removed dead code that permitted disabling of
-	recognition of the new 0b and 0o numeric formats.
-
-	* generic/tclExecute.c: Removed dead code that implemented alternative
-	* generic/tclObj.c:	design where numeric values did not
-	automatically narrow to the smallest Tcl_ObjType required to hold them
-
-	* generic/tclCmdAH.c:	Removed dead code that was old implementation
-	of [format].
-
-2006-06-14  Daniel Steffen  <das@users.sourceforge.net>
-
-	* unix/tclUnixPort.h (Darwin): support 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  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
-
-	* doc/format.n, doc/scan.n: Added examples for converting between
-	characters and their numeric interpretations following user prompting.
-
-2006-06-13  Donal K. Fellows  <dkf@users.sf.net>
-
-	* 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().
-
-2006-06-05  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
-
-	* doc/Alloc.3: Added documentation of promise that Tcl_Realloc(NULL,x)
-	is the same as Tcl_Alloc(x), as discussed in comp.lang.tcl. Also fixed
-	nonsense sentence to say something meaningful.
-
-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
-	* unix/tclConfig.h.in: autoheader-2.59

-	awk; it was a rarely used branch, but it was wrong. [Bug 1494160]
-
-2006-05-23  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
-
-	* doc/chan.n, doc/refchan.n: Tighten up the documentation to follow a
-	slightly more consistent style with regard to argument capitalization.
-
-2006-05-13  Don Porter	<dgp@users.sourceforge.net>
-
-	* 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.
-
-2006-05-13  Daniel Steffen  <das@users.sourceforge.net>
-
-	* generic/tclEvent.c (HandleBgErrors): fix leak. [Coverity issue 86]
-

-
-	* 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]

-	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]

-
-2006-04-05  Don Porter	<dgp@users.sourceforge.net>
-
-	* win/tclWinInit.c:	More careful calls to Tcl_DStringSetLength()
-	* win/tclWinSock.c:	to avoid creating invalid DString states. Bump
-	* win/tclWinDde.c:	to version 1.3.2. [RFE 1366195]
-	* library/dde/pkgIndex.tcl:
-
-	* library/reg/pkgIndex.tcl:	Bump to registry 1.2 because

-2006-04-05  Donal K. Fellows  <donal.k.fellows@manchester.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]
-
-2006-04-03  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].
-
-2006-03-30  Miguel Sofer  <msofer@users.sf.net>
-

-
-2006-03-27  Andreas Kupries <andreask@activestate.com>
-
-	* doc/CrtChannel.3:    Added TCL_CHANNEL_VERSION_5, made it the
-	* generic/tcl.h:       version where the "truncateProc" is defined at,
-	* generic/tclIO.c:     and moved all channel drivers of Tcl to v5.

-
-2006-03-27  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclExecute.c: Merge INST_MOD computation in with the
-	INST_?SHIFT instructions, which also operate only on two integral
-	values. Also corrected flaw that made INST_BITNOT of wide values
-	require mp_int calculations. Also corrected type that missed optimized
-	handling of the tclBooleanType by the TclGetBooleanFromObj macro.
-
-	* changes:	Updates for another RC.
-
-2006-03-25  Don Porter	<dgp@users.sourceforge.net>

-2006-03-24  Kevin B. Kenny  <kennykb@acm.org>
-
-	* generic/tclExecute.c (TclExecuteByteCode): Added a couple of missing
-	casts to 'int' that were affecting compilablity on VC6.
-
-2006-03-24  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclEncoding.c: Reverted latest change [Bug 506653] since it
-	reportedly killed test performance on Windows.
-
-	* generic/tclExecute.c: Revised INST_EXPON implementation to do
-	calculations in native types as much as possible, moving to mp_ints
-	only when necessary.
-
-2006-03-23  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclExecute.c: Merged INST_EXPON handling in with the other
-	binary operators that operate on all number types (INST_ADD, etc.).
-
-	* tests/env.test: With case preserved (see 2006-03-21 commit) be sure
-	to do case-insensitive filtering. [Bug 1457065]
-
-2006-03-23  Reinhard Max  <max@suse.de>
-
-	* unix/tcl.spec: Cleaned up and completed the spec file. An RPM can

-	<tarball>"
-
-2006-03-22  Reinhard Max  <max@suse.de>
-
-	* tests/stack.test: Run the stack tests in subshells, so that they are

-
-	* changes:	Updates for another RC.

-	* generic/tclInt.decls:	 implement globbing for HFS creator & type
-	* macosx/tclMacOSXFCmd.c:codes and 'hidden' flag, as documented in
-	* tests/macOSXFCmd.test: glob.n; objectified OSType handling in [glob]
-	* unix/tclUnixFile.c:	 and [file attributes]; fix globbing for
-	hidden files with pattern==NULL arg. [Bug 823329]
-	* generic/tclIntPlatDecls.h:
-	* generic/tclStubInit.c: make genstubs
-
-2006-03-20  Andreas Kupries <andreask@activestate.com>
-
-	* win/Makefile.in (install-libraries): Generate tcl8/8.4 directory
-	under Windows as well (cygwin Makefile). Related entry: 2006-03-07,
-	dgp. This moved the installation of http from 8.2 to 8.4, partially. A
-	fix of the required directory creation was done for unix on Mar 10,
-	without entry in the Changelog. This entry is for the fix of the
-	directory creation under Windows.
-
-	* unix/installManPage: There is always one even more broken "sed".
-	Moved the # comment starting character in the sed script to the
-	beginning of their respective lines. The AIX sed will not recognize
-	them as comments otherwise :( The actual text stays indented for
-	better association with the commands they belong to.
-

-2006-03-18  Vince Darley  <vincentdarley@sourceforge.net>
-
-	* generic/tclFileName.c:
-	* doc/FileSystem.3:
-	* tests/fileName.test: Fix to [Bug 1084705] so that 'glob -nocomplain'
-	finally agrees with its documentation and doesn't swallow genuine
-	errors.
-
-	***POTENTIAL INCOMPATIBILITY*** for scripts that assumed '-nocomplain'
-	removes the need for 'catch' to deal with non-understood path names.
-
-	Small optimisation to implementation of pattern==NULL case of TclGlob,
-	and clarification to the documentation. [Tclvfs bug 1405317]
-
-2006-03-18  Vince Darley  <vincentdarley@sourceforge.net>
-
-	* tests/fCmd.test: added knownBug test case for [Bug 1394972]
-
-	* tests/winFCmd.test:

-	of writable/non-writable directories on Windows 2000/XP. This, with
-	the previous patches, closes [Bug 1193497]
-
-2006-03-17  Andreas Kupries <andreask@activestate.com>
-
-	* doc/chan.n: Updated with documentation for the commands 'chan
-	create' and 'chan postevent' (TIP #219).

-
-	* 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]

-	[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>
-
-	* doc/clock.n: Removed double-quotes around section title NAME; not
-	needed.

-
-	* 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

-	* generic/tclInt.h: Added TclpFinalizeSockets() call.
-
-	* generic/tclIO.c: Calls TclpFinalizeSockets() as part of the

-	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.

-2006-02-28  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclBasic.c:	Corrections to be sure that TCL_EVAL_GLOBAL
-	* tests/namespace.test: evaluations act the same as [uplevel #0]
-	* tests/parse.test:	evaluations, even when execution traces or

-2006-02-15  Don Porter	<dgp@users.sourceforge.net>
-
-	* generic/tclIO.c:	Made several routines tolerant of

-	* generic/tclIOUtil.c:
-
-2006-02-09  Don Porter	<dgp@users.sourceforge.net>
-

-
-	* unix/tclUnixChan.c (TclpOpenFileChannel): Tidy up and comment the
-	mess to do with setting up serial channels. This (deliberately) breaks

-
-2006-01-25  Donal K. Fellows  <dkf@users.sf.net>
-
-	* unix/tclUnixInit.c (TclpInitPlatform): Improved conditions on when

-
-	* generic/tclProc.c: fixed args handling for precompiled bodies [Bug
-	1412695]; thanks to Uwe Traum.
-
-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/tclPathObj.c (Tcl_FSGetInternalRep): backported patch from

-	* generic/tclBasic.c:	Moved Tcl_LogCommandInfo from tclBasic.c to
-	* generic/tclNamesp.c:	tclNamesp.c to get access to identifier with
-	* tests/error.test (error-7.0): file scope. Added check for traces on
-	::errorInfo, and when present fall back to contruction of the stack
-	trace in the variable so that write trace notification timings are
-	compatible with earlier Tcl releases. This reduces, but does not
-	completely eliminate the ***POTENTIAL INCOMPATIBILITY*** created by
-	the 2004-10-15 commit. [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 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]
-
-2006-01-09  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
-
-	* generic/tclTrace.c: Stop exporting the guts of the trace command;
-	nothing outside this file needs to see it. [Bug 971336]
-
-2006-01-05  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
-
-	* unix/tcl.m4 (TCL_CONFIG_SYSTEM): Factor out the code to determine
-	the operating system version number, as it was replicated in several
-	places.
-
-2006-01-04  David Gravereaux  <davygrvy@pobox.com>
-
-	* win/tclAppInit.c: WIN32 native console signal handler removed. This
-	was found to be interfering with TWAPI extension one. IMO, special
-	services such as signal handlers should best be done with extensions
-	to the core after discussions on c.l.t. about Roy Terry's tclsh
-	children of a real windows service shell.

+
+2007-12-26  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclCmdIL.c: More [lsort] data handling streamlines. The
+	function MergeSort is gone, essentially inlined into Tcl_LsortObjCmd.
+	It is not a straight inlining, two loops over all lists elements where

+	merged into the temporary sublists in the same pass.

+2007-12-25  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclCmdIL.c: More [lsort] data handling streamlines. Extra

+	* generic/tclCompCmds.c (TclCompileSwitchCmd): Adjusted the [switch]
+	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd):       command so that when

+
+2007-11-23  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIORChan.c: Fixed a problem with reflected channels. 'chan
+	postevent' is defined to work only from within the interpreter
+	containing the handler command. Sensible, we want only handler
+	commands to use it. It identifies the channel by handle. The channel
+	moves to a different interpreter or thread. The interpreter containing
+	the handler command doesn't know the channel any longer. 'chan
+	postevent' fails, not finding the channel any longer. Uhm.
+
+	Fixed by creating a second per-interpreter channel table, just for
+	reflected channels, where each interpreter remembers for which
+	reflected channels it has the handler command. This info does not move
+	with the channel itself. The table is updated by 'chan create', and
+	used by 'chan postevent'.
+
+	* tests/ioCmd.test: Updated the testsuite.

+
+	* tests/string.test (string-12.22): Flag shimmering bug found in
+	[string range].
+
+2007-11-21  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileEnsemble): Rewrote the ensemble
+	compiler to remove many of the limitations. Can now compile scripts
+	that use unique prefixes of subcommands, and which have mappings of a
+	command to multiple words (provided the first is a compilable command
+	of course).
+
+2007-11-21  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

+	* generic/various: Start to return more useful Error codes, currently
+	mainly on assorted lookup failures.
+
+2007-11-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclDictObj.c: Changed the underlying implementation of the
+	hash table used in dictionaries to additionally keep all entries in
+	the hash table in a linked list, which is only ever added to at the
+	end. This makes iteration over all entries in the dictionary in
+	key insertion order a trivial operation, and so cleans up a great deal
+	of complexity relating to dictionary representation and stability of
+	iteration order.
+
+	***POTENTIAL INCOMPATIBILITY***
+	For any code that depended on the (strange) old iteration order.
+

+
+	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Allow people to turn off the -rpath
+	option to their linker if they so desire. This is a configuration only

+
+2007-11-15  Pat Thoyts	<patthoyts@users.sourceforge.net>
+

+
+	* generic/tclNamesp.c (Tcl_SetEnsembleSubcommandList)

+	* generic/tclCompCmds.c (TclCompileInfoCmd): Simple compiler for the

+
+	* generic/tclExecute.c (TclExecuteByteCode:INST_EXIST_*): New
+	instructions to allow the testing of whether a variable exists.
+
+2007-11-14  Andreas Kupries  <andreask@activestate.com>

+
+2007-11-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

+
+2007-11-13  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileSwitchCmd, TclCompileRegexpCmd):
+	Extend [switch] compiler to handle regular expressions as long as

+	literal regexps get fed to INST_REGEXP.
+
+	* doc/mathop.n: Clarify definitions of some operations.

+2007-11-13  Miguel Sofer  <msofer@users.sf.net>
+
+	* unix/tclUnixInit.c: the TCL_NO_STACK_CHECK was being incorrectly

+
+2007-11-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* unix/tclUnixChan.c (CreateSocketAddress): Rewrote to use the
+	thread-safe version of gethostbyname() by forward-porting the code
+	used in 8.4, and added rudimentary support for getaddrinfo() (not
+	enabled by default, as no autoconf-ery written). Part of fix for [Bug
+	1618235].
+
+2007-11-12  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* generic/tclGet.c (Tcl_Get, Tcl_GetInt): revert use of TclGet* macros

+
+	* generic/tclUtil.c (TclReToGlob): add more comments, set interp
+	result if specified on error.
+
+2007-11-12  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c:		New macro TclResetResult, new iPtr

+
+2007-11-10  Kevin Kenny	 <kennykb@acm.org>
+
+	* win/tclWin32Dll.c: Rewrote the Windows stack checking algorithm to
+	use information from VirtualQuery to determine the bound of the stack.
+	This change fixes a bug where the guard page of the stack was never
+	restored after an overflow. It also eliminates a nasty piece of
+	assembly code for structured exception handling on mingw. It
+	introduces an assumption that the stack is a single memory arena
+	returned from VirtualAlloc, but the code in MSVCRT makes the same
+	assumption, so it should be fairly safe.

+	* generic/tclInterp.c (Tcl_Init):	Removed constraint on ability
+	to define a custom [tclInit] before calling Tcl_Init(). Until now the
+	custom command had to be a proc. Now it can be any command.
+
+	* generic/tclInt.decls: New internal routine TclBackgroundException()
+	* generic/tclEvent.c:	that for the first time permits non-TCL_ERROR
+	exceptions to trigger [interp bgerror] handling. Closes a gap in TIP
+	221. When falling back to [bgerror] (which is designed only to handle
+	TCL_ERROR), convert exceptions into errors complaining about the
+	exception.
+
+	* generic/tclInterp.c:	Convert Tcl_BackgroundError() callers to call
+	* generic/tclIO.c:	TclBackgroundException().
+	* generic/tclIOCmd.c:
+	* generic/tclTimer.c:
+
+	* generic/tclIntDecls.h:	make genstubs
+	* generic/tclStubInit.c:

+2007-09-06  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/Tcl.xcode/project.pbxproj: discontinue unmaintained support
+	* macosx/Tcl.xcode/default.pbxuser: for Xcode 1.5; replace by Xcode2
+	project for use on Tiger (with Tcl.xcodeproj to be used on Leopard).
+
+	* macosx/Tcl.xcodeproj/project.pbxproj: updates for Xcode 2.5 and 3.0.

+
+2007-09-04  Don Porter	<dgp@users.sourceforge.net>
+
+	* unix/Makefile.in:	It's unreliable to count on the release
+	manager to remember to `make genstubs` before `make dist`. Let the
+	Makefile remember the dependency for us.
+

+
+2007-09-03  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclObj.c (TclInitObjSubsystem): restore registration of the

+
+2007-09-02  Donal K. Fellows  <dkf@users.sf.net>

+
+2007-08-30  Don Porter	<dgp@users.sourceforge.net>
+

+
+2007-08-27  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Call TclCompileSyntaxError() when

+	* generic/tclCompile.c: Update callers.

+
+	* generic/tclCompCmds.c:	New routine TclCompileSyntaxError()
+	* generic/tclCompile.h: to directly compile bytecodes that report a
+	* generic/tclCompile.c: syntax error, rather than (ab)use a call to
+	TclCompileReturnCmd. Also, undo the most recent commit that papered
+	over some issues with that (ab)use. New routine produces a new opcode
+	INST_SYNTAX, which is a minor variation of INST_RETURN_IMM. Also a bit
+	of constification.
+

+	* generic/tclCompExpr.c:	entries into TclFreeCompileEnv().
+	* generic/tclExecute.c: Update callers.
+
+	* generic/tclCompExpr.c:	Force numeric and boolean literals in

+	overwriting existing intreps in already registered literals.
+
+2007-08-25  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclExecute.c (TclExecuteByteCode): Added code to handle

+	that results in 32- and 64-bit integer results, avoiding calls to wide
+	integer exponentiation routines in this common case. [Bug 1767293]

+
+	* generic/tclCompCmds.c (TclCompileReturnCmd):	Added crash protection
+	to handle callers other than TclCompileScript() failing to meet the

+
+	* generic/tclCompExpr.c:	Suppress the attempt to convert to

+
+2007-08-20  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c (INST_SUB): fix usage of the new macro for

+
+2007-08-19  Donal K. Fellows  <dkf@users.sf.net>
+

+	Encapsulate Miguel's last change in a more mnemonic macro.
+
+2007-08-19  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c: changed the check for overflow in sums,
+	reducing objsize, number of branches and cache misses (according to
+	cachegrind). Non-overflow for s=a+b:
+	previous
+	  ((a >= 0 || b >= 0 || s < 0) && (s >= 0 || b < 0 || a < 0))
+	now
+	  (((a^s) >= 0) || ((a^b) < 0))

+	subexpressions at compile time. This resolves the issue raised in [Bug

+2007-08-10  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Revise CompileExprTree() to use the

+2007-08-06  Don Porter	<dgp@users.sourceforge.net>
+
+	* tests/parseExpr.test: Update source file name of expr parser code.
+
+	* generic/tclCompExpr.c:	Added a "mark" field to the OpNode

+	nothing since alignement requirements used the memory already.
+	Rewrote ConvertTreeToTokens() to use the new field, which permitted
+	consolidation of utility routines CopyTokens() and

+
+	*** POTENTIAL INCOMPATIBILITY *** (tclInt.h and tclCompile.h)
+	Extensions that access internals defined in tclInt.h and/or
+	tclCompile.h may lose both binary and source compatibility. The
+	relevant changes are:
+	1. 'struct Var' is completely changed, all acceses to its internals
+	   (either direct or via the TclSetVar* and TclIsVar* macros) will
+	   malfunction. Var flag values and semantics changed too.
+	2. 'struct Bytecode' has an additional field that has to be
+	   initialised to NULL
+	3. 'struct Namespace' is larger, as the varTable is now one pointer
+	   larger than a Tcl_HashTable. Direct access to its fields will
+	   malfunction.
+	4. 'struct CallFrame' grew one more field (the second such growth with
+	   respect to Tcl8.4).
+	5. API change for the functions TclFindCompiledLocal, TclDeleteVars
+	   and many internal functions in tclVar.c
+
+	Additionally, direct access to variable hash tables via the standard
+	Tcl_Hash* interface is to be considered as deprecated. It still works
+	in the present version, but will be broken by further specialisation
+	of these hash tables. This concerns especially the table of array
+	elements in an array, as well as the varTable field in the Namespace
+	struct.

+	* generic/tclTrace.c (TclCheck(Interp|Execution)Traces):
+	Removed the need for TEBC to inspect the command before calling TEOvI,

+2007-07-20  Andreas Kupries  <andreask@activestate.com>
+

+	* library/platform/pkgIndex.tcl: where identifiers not matching
+	* unix/Makefile.in: the special linux and solaris forms would not
+	* win/Makefile.in: get 'tcl' as an acceptable platform added to
+	* doc/platform.n: the result. Bumped package to version 1.0.3 and
+	* doc/platform_shell.n: updated documentation and Makefiles. Also
+	fixed bad version info in the documentation of platform::shell.
+
+2007-07-19  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclParse.c:	In contexts where interp and parsePtr->interp
+	might be different, be sure to use the latter for error reporting.
+	Also pulled the interp argument back out of ParseTokens() since we
+	already had a parsePtr->interp to work with.
+
+2007-07-18  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Removed unused arguments and variables
+
+2007-07-17  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c (ParseExpr):	While adding comments to
+	explain the operations of ParseExpr(), made significant revisions to
+	the code so it would be easier to explain, and in the process made the
+	code simpler and clearer as well.
+
+2007-07-15  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	More commentary.
+	* tests/parseExpr.test:		Several tests of syntax error messages
+	to check that when expression substrings are truncated they leave
+	visible the context relevant to the reported error.
+
+2007-07-12  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Factored out, corrected, and commented
+	common code for reporting syntax errors in LEAF elements.
+
+2007-07-11  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileWhileCmd):
+	* generic/tclCompile.c (TclCompileScript):
+	Corrected faulty avoidance of INST_START_CMD when the first opcode in
+	a script is within a loop (as produced by 'while 1'), so that the
+	corresponding command is properly counted. [Bug 1752146]
+
+2007-07-11  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Added a "parseOnly" flag argument to
+	ParseExpr() to indicate whether the caller is Tcl_ParseExpr(), with an
+	end goal of filling a Tcl_Parse with Tcl_Tokens representing the
+	parsed expression, or TclCompileExpr() with the goal of compiling and
+	executing the expression. In the latter case, more aggressive
+	conversion of QUOTED and BRACED lexeme to literals is done. In the
+	former case, all such conversion is avoided, since Tcl_Token
+	production would revert it anyway. This enables simplifications to the
+	GenerateTokensForLiteral() routine as well.
+
+2007-07-10  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Added a field for operator precedence
+	to be stored directly in the parse tree. There's no memory cost to
+	this addition, since that memory would have been lost to alignment
+	issues anyway. Also, converted precedence definitions and lookup
+	tables to use symbolic constants instead of raw number for improved

+
+	* generic/tclCompExpr.c:	Revision so that the END lexeme never

+
+	***POTENTIAL INCOMPAT*** There is a subtle issue with the timing of
+	execution traces that is changed here - first change appeared in my
+	commit of 2007-04-03 [Patch 1693802], which caused some divergence

+
+	* generic/tclExecute.c (INST_INVOKE): isolated two vars to the small

+
+	* generic/tclObj.c (Tcl_GetCommandFromObj): rewritten to make the
+	logic clearer; slightly faster too.
+
+	* generic/tclBasic.c:	Split TEOv in two, by separating a processor
+	for non-TCL_OK returns. Also split TEOvI in a full version that
+	handles non-existing and traced commands, and a separate shorter
+	version for the regular case.
+
+	* generic/tclBasic.c:	Moved the generation of command strings for
+	* generic/tclTrace.c:	traces: previously in Tcl_EvalObjv(), now in
+	TclCheck[Interp|Execution]Traces(). Also insured that the strings are
+	properly NUL terminated at the correct length. [Bug 1693986]
+
+	***POTENTIAL INCOMPATIBILITY in internal API***
+	The functions TclCheckInterpTraces() and TclCheckExecutionTraces() (in
+	internal stubs) used to be noops if the command string was NULL, this
+	is not true anymore: if the command string is NULL, they generate an
+	appropriate string from (objc,objv) and use it to call the traces. The
+	caller might as well not call them with a NULL string if he was
+	expecting a noop.
+
+	* generic/tclBasic.c:	Extend usage of TclLimitReady() and
+	* generic/tclExecute.c: (new) TclLimitExceeded() macros.
+	* generic/tclInt.h:

+2007-05-09  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclInt.h:	TclFinalizeThreadAlloc() is always defined, so
+	make sure it is also always declared (with MODULE_SCOPE).
+
+2007-05-09  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclInt.h: fix warning when building threaded with -DPURIFY.
+
+	* macosx/Tcl.xcodeproj/project.pbxproj: add 'DebugUnthreaded' &
+	* macosx/Tcl.xcodeproj/default.pbxuser: 'DebugLeaks' configs and env

+2007-05-07  Don Porter	<dgp@users.sourceforge.net>
+
+	[Tcl Bug 1706140]
+
+	* generic/tclLink.c (LinkTraceProc):	Update Tcl_VarTraceProcs so
+	* generic/tclNamesp.c (Error*Read):	they call Tcl_InterpDeleted()
+	* generic/tclTrace.c (Trace*Proc):	for themselves, and do not
+	* generic/tclUtil.c (TclPrecTraceProc): rely on (frequently buggy)
+	setting of the TCL_INTERP_DESTROYED flag by the trace core.
+
+	* generic/tclVar.c:	Update callers of TclCallVarTraces 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/tclTrace.c (TclCallVarTraces):	The setting of the
+	TCL_INTERP_DESTROYED flag is now done entirely within the
+	TclCallVarTraces routine, the only place it can be done right.
+
+2007-05-06  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclInt.h (ExtraFrameInfo): Create a new mechanism for
+	* generic/tclCmdIL.c (InfoFrameCmd): conveying what information needs
+	to be added to the results of [info frame] to replace the hack that
+	was there before.
+	* generic/tclProc.c (Tcl_ApplyObjCmd): Use the new mechanism for the
+	[apply] command, the only part of Tcl itself that needs it (so far).
+
+	* generic/tclInt.decls (TclEvalObjEx, TclGetSrcInfoForPc): Expose
+	these two functions through the internal stubs table, necessary for
+	extensions that need to integrate deeply with TIP#280.
+
+2007-05-05  Donal K. Fellows  <dkf@users.sf.net>
+
+	* win/tclWinFile.c (TclpGetUserHome):	Squelch type-pun warnings in
+	* win/tclWinInit.c (TclpSetVariables):	Win-specific code not found
+	* win/tclWinReg.c (AppendSystemError):	during earlier work on Unix.
+
+2007-05-04  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclIO.c (TclFinalizeIOSubsystem): Added an initializer to
+	silence a spurious gcc warning about use of an uninitialized
+	variable.
+	* tests/encoding.test: Modified so that encoding tests happen in a
+	private namespace, to avoid polluting the global one. This problem was
+	discovered when running the test suite '-singleproc 1 -skip exec.test'
+	because the 'path' variable in encoding.test conflicted with the one
+	in io.test.
+	* tests/io.test: Made more of the working variables private to the
+	namespace.
+
+2007-05-02  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclTest.c (SimpleMatchInDirectory): Corrected a refcount
+	imbalance that affected the filesystem-[147]* tests in the test suite.
+	Thanks to Don Porter for the patch. [Bug 1710707]
+	* generic/tclPathObj.c (Tcl_FSJoinPath, Tcl_FSGetNormalizedPath):
+	Corrected several memory leaks that caused refcount imbalances
+	resulting in memory leaks on Windows. Thanks to Joe Mistachkin for the
+	patch.
+
+2007-05-01  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclVar.c (TclPtrSetVar): fixed leak whenever newvaluePtr had
+	refCount 0 and was used for appending (but not lappending). Thanks to
+	mistachkin and kbk. [Bug 1710710]
+
+2007-05-01  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclIO.c (DeleteChannelTable): Made changes so that
+	DeleteChannelTable tries to close all open channels, not just the
+	first. [Bug 1710285]
+	* generic/tclThread.c (TclFinalizeSynchronization): Make sure that TSD
+	blocks get freed on non-threaded builds. [Bug 1710825]
+	* tests/utf.test (utf-25.1--utf-25.4): Modified tests to clean up
+	after the 'testobj' extension to avoid spurious reports of memory
+	leaks.
+
+2007-05-01  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c (STR_MAP): When [string map] has a pure dict map,
+	a missing Tcl_DictObjDone() call led to a memleak. [Bug 1710709]
+
+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.
+
+2007-04-30  Andreas Kupries <andreask@gactivestate.com>
+
+	* generic/tclIO.c (FixLevelCode): Corrected reference count
+	mismanagement of newlevel, newcode. Changed to allocate the Tcl_Obj's
+	as late as possible, and only when actually needed. [Bug 1705778, leak
+	K29]
+
+2007-04-30  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclProc.c (Tcl_ProcObjCmd, SetLambdaFromAny): Corrected
+	reference count mismanagement on the name of the source file in the
+	TIP 280 code. [Bug 1705778, leak K02 among other manifestations]
+
+2007-04-25  Donal K. Fellows  <dkf@users.sf.net>
+
+	*** 8.5a6 TAGGED FOR RELEASE ***
+
+	* generic/tclProc.c (TclObjInterpProcCore): Only allocate objects for
+	error message generation when associated with argument names that are
+	really used. [Bug 1705778, leak K15]
+
+2007-04-25  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclIOUtil.c (Tcl_FSChdir): Changed the memory management so
+	that the path returned from Tcl_FSGetNativePath is not duplicated
+	before being stored as the current directory, to avoid a memory leak.
+	[Bug 1705778, leak K01 among other manifestations]
+
+2007-04-25  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c (ParseExpr):	Revised to be sure that an
+	error return doesn't prevent all literals getting placed on the
+	litList to be returned to the caller for freeing. Corrects some
+	memleaks. [Bug 1705778, leak K23]
+
+2007-04-25  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/Makefile.in (dist): add macosx/*.xcconfig files to src dist;
+	copy license.terms to dist macosx dir; fix autoheader bits.
+
+2007-04-24  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclListObj.c: reverting [Patch 738900] (committed on
+	2007-04-20). Causes some Tk test breakage of unknown importance, but
+	the impact of the patch itself is likely to be so small that it does
+	not warrant investigation at this time.
+
+2007-04-24  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclDictObj.c (DictKeysCmd): Rewrote so that the lock on the
+	internal representation of a dict is only set when necessary. [Bug
+	1705778, leak K04]
+	(DictFilterCmd): Added code to drop the lock in the trivial match
+	case. [Bug 1705778, leak K05]
+
+2007-04-24  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclBinary.c: Addressed several code paths where the error
+	return from the 'binary format' command leaked the result buffer.
+	* generic/tclListObj.c (TclLsetFlat): Fixed a bug where the new list
+	under construction was leaked in the error case. [Bug 1705778, leaks
+	K13 and K14]
+
+2007-04-24  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* unix/Makefile.in (dist): add platform library package to src dist
+
+2007-04-24  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c (ParseExpr): Memory leak in error case; the
+	literal Tcl_Obj was not getting freed. [Bug 1705778, leak #1 (new)]
+
+	* generic/tclNamesp.c (Tcl_DeleteNamespace):	Corrected flaw in the
+	flag marking scheme to be sure that global namespaces are freed when
+	their interp is deleted. [Bug 1705778]
+
+2007-04-24  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclExecute.c (TclExecuteByteCode): Plugged six memory leaks
+	in bignum arithmetic.
+	* generic/tclIOCmd.c (Tcl_ReadObjCmd): Plugged a leak of the buffer
+	object if the physical read returned an error and the bypass area had
+	no message.
+	* generic/tclIORChan.c (TclChanCreateObjCmd): Plugged a leak of the
+	return value from the "initialize" method of a channel handler.
+	(All of the above under [Bug 1705778])
+
+2007-04-23  Daniel Steffen  <das@users.sourceforge.net>

+	* macosx/Tcl-Common.xcconfig: enable more warnings.
+
+	* macosx/Tcl.xcodeproj/project.pbxproj: add 'DebugMemCompile' build

+
+2007-04-23  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclCompile.c (TclFreeCompileEnv): Tip 280's new field

+
+2007-04-23  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclCompCmds.c (TclCompileUpvarCmd): Plugged a memory leak in
+	'upvar' when compiling (a) upvar outside a proc, (b) upvar with a
+	syntax error, or (c) upvar where the frame index is not known at
+	compile time.
+	* generic/tclCompExpr.c (ParseExpr): Plugged a memory leak when

+	with a string of more than 'maxpow10_wide' zeroes.
+	* generic/tclTest.c (Testregexpobjcmd): Removed an invalid access
+	beyond the end of 'objv' in 'testregexp -about'.
+	All of these issues reported under [Bug 1705778] - detected with the
+	existing test suite, no new regression tests required.
+
+2007-04-22  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclVar.c (TclDeleteNamespaceVars): fixed access to freed
+	memory detected by valgrind: Tcl_GetCurrentNamespace was being
+	called after freeing root CallFrame (on interp deletion).
+
+2007-04-20  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclListObj.c (SetListFromAny): avoid discarding internal
+	reps of objects converted to singleton lists. [Patch 738900]
+
+2007-04-20  Kevin B. Kenny  <kennykb@acm.org>
+
+	* doc/clock.n: Corrected a silly error (transposed 'uppercase' and
+	'lowercase' in clock.n. [Bug 1656002]
+	Clarified that [clock scan] does not recognize a locale's alternative
+	calendar.
+	Deleted an entirely superfluous (and also incorrect) remark about the
+	effect of Daylight Saving Time on relative times in [clock scan]. [Bug
+	1582951]
+	* library/clock.tcl: Corrected an error in skipping over the %Ey field
+	on input.
+	* library/msgs/ja.msg:
+	* tools/loadICU.tcl: Corrected several localisation faults in the
+	Japanese locale (most notably, incorrect dates for the Emperors'
+	eras). Many thanks to SourceForge user 'nyademo' for pointing this out
+	and developing a fix. [Bug 1637471]
+	* generic/tclPathObj.c: Corrected a 'const'ness fault that caused
+	bitter complaints from MSVC.
+	* tests/clock.test (clock-40.1, clock-58.1, clock-59.1): Corrected a
+	test case that depended on ":localtime" being able to handle dates
+	prior to the Posix epoch. [Bug 1618445] Added a test case for the
+	dates of the Japanese emperors. [Bug 1637471] Added a regression test
+	for military time zone input conversion. [Bug 1586828]
+	* generic/tclGetDate.y (MilitaryTable): Fixed an ancient bug where the
+	military NZA time zones had the signs reversed. [Bug 1586828]
+	* generic/tclDate.c: Regenerated.
+	* doc/Notifier.3: Documented Tcl_SetNotifier and Tcl_ServiceModeHook.

+2007-04-19  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/regcomp.c, generic/regc_cvec.c, generic/regc_lex.c,

+	compiler.
+
+2007-04-18  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c (INST_LSHIFT): fixed a mistake introduced in
+	version 1.266 ('=' became '=='), which effectively turned the block
+	that handles native shifts into dead code. This explains why the
+	testsuite did not pick this mistake. Rewrote to make the intention
+	clear.
+
+	* generic/tclInt.h (TclDecrRefCount): change the order of the
+	branches, use empty 'if ; else' to handle use in unbraced outer
+	if/else conditions (as already done in tcl.h)
+
+	* generic/tclExecute.c: slight changes in Tcl_Obj management.
+
+2007-04-17  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/clock.tcl: Fixed the naming of
+	::tcl::clock::ReadZoneinfoFile because (yoicks!) it was in the global
+	namespace.
+	* doc/clock.n: Clarified the cases in which legacy time zone is
+	recognized. [Bug 1656002]
+
+2007-04-17  Miguel Sofer  <msofer@users.sf.net>

+	function definitions from manually-written code.
+
+2007-04-15  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclCompCmds.c: added a cast to silence a compiler error on
+	VC2005.
+	* library/clock.tcl: Restored unique-prefix matching of keywords on
+	the [clock] command. [Bug 1690041]
+	* tests/clock.test: Added rudimentary test cases for unique-prefix
+	matching of keywords.
+
+2007-04-14  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c: removed some code at INST_EXPAND_SKTOP that
+	duplicates functionality already present at checkForCatch.
+
+2007-04-12  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c: new macros OBJ_AT_TOS, OBJ_UNDER_TOS,
+	OBJ_AT_DEPTH(n) and CURR_DEPTH that remove all direct references to
+	tosPtr from TEBC (after initialisation and the code at the label
+	cleanupV_pushObjResultPtr).
+
+2007-04-11  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclCompCmds.c: moved all exceptDepth management to the
+	macros - the decreasing half was managed by hand.
+
+2007-04-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclInt.h (TclNewLiteralStringObj): New macro to make
+	allocating literal string objects (i.e. objects whose value is a
+	constant string) easier and more efficient, by allowing the omission
+	of the length argument. Based on [Patch 1529526] (afredd)
+	* generic/*.c: Make use of this (in many files).
+
+2007-04-08  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclCompile (tclInstructionTable): Fixed bugs in description
+	of dict instructions.

+
+2007-04-03  Miguel Sofer  <msofer@users.sf.net>
+

+
+2007-04-03  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclNamesp.c:	Revised ErrorCodeRead and ErrorInfoRead trace

+
+	* generic/tclCompile.c (TclCompileScript, TclPrintInstruction):
+	* generic/tclExecute.c (TclExecuteByteCode): Changed the definition of
+	INST_START_CMD so that it knows how many commands start at the current
+	location. This makes the interpreter command counter correct without
+	requiring a large number of instructions to be issued. (See my change
+	from 2007-01-19 for what triggered this.)
+
+2007-03-30  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompile.c:
+	* generic/tclCompExpr.c:
+	* generic/tclCompCmds.c:	Replace arrays on the C stack and
+	ckalloc calls with TclStackAlloc calls to use memory on Tcl's
+	evaluation stack.
+
+	* generic/tclCmdMZ.c:	Revised [string to* $s $first $last]
+	implementation to reduce number of allocs/copies.
+
+	* tests/string.test:  More [string reverse] tests.
+
+2007-03-30  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c: optimise the lookup of elements of indexed
+	arrays.
+
+2007-03-29  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclProc.c (Tcl_ApplyObjCmd):
+	* tests/apply.test (9.3): Fixed Tcl_Obj leak on error return; an
+	unneeded ref to lambdaPtr was being set and not released on an error
+	return path.
+
+2007-03-28  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c (STR_REVERSE):	Implement the actual [string
+	reverse] command in terms of the new TclStringObjReverse() routine.
+
+	* generic/tclInt.h (TclStringObjReverse):	New internal routine
+	* generic/tclStringObj.c (TclStringObjReverse): that implements the
+	[string reverse] operation, making use of knowledge/surgery of the
+	String intrep to minimize the number of allocs and copies needed to do
+	the job.
+
+2007-03-27  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdMZ.c (STR_MAP): Replace ckalloc calls with
+	TclStackAlloc calls.
+
+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.
+
+2007-03-23  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclBasic.c (DeleteInterpProc): pop the root frame pointer
+	before deleting the global namespace [Bug 1658572]
+
+2007-03-23  Kevin B. Kenny  <kennykb@acm.org>
+
+	* win/Makefile.in: Added code to keep a Cygwin path name from leaking
+	into LIBRARY_DIR when doing 'make test' or 'make runtest'.
+
+2007-03-22  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdAH.c (Tcl_ForeachObjCmd):	Replaced arrays on the
+	C stack and ckalloc calls with TclStackAlloc calls to use memory on
+	Tcl's evaluation stack.
+
+	* generic/tclExecute.c: Revised GrowEvaluationStack to take an
+	argument specifying the growth required by the caller, so that a
+	single reallocation / copy is the most that will ever be needed even

+
+2007-03-09  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/clock.tcl (ReadZoneinfoFile): Added Y2038 compliance to the
+	code for version-2 'zoneinfo' files.
+	* tests/clock.test (clock-56.3): Added a test case for Y2038 and

+
+2007-03-08  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclListObj.c (TclLsetList):	Rewrite so that the routine

+
+2007-03-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclListObj.c (TclLindexList, TclLindexFlat): Moved these

+
+2007-03-08  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/clock.tcl: Further tweaks to the Windows time zone table
+	(restoring missing Mexican time zones). Added rudimentary handling of
+	version-2 'zoneinfo' files. Update US DST rules so that zones such as
+	'EST5EDT' get the correct transition dates.
+	* tests/clock.test: Added rudimentary test cases for 'zoneinfo'

+	transition rules.
+
+2007-03-07  Daniel Steffen  <das@users.sourceforge.net>
+
+	* macosx/tclMacOSXNotify.c: add spinlock debugging and sanity checks.

+
+2007-03-07  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdIL.c (TclLindex*):	Rewrites to make efficient
+	private copies of the list and indexlist arguments, so we can operate
+	on the list elements directly with no fear of shimmering effects.
+	Replaces defensive coding schemes that are otherwise required. End
+	result is that TclLindexList is entirely a wrapper around
+	TclLindexFlat, which is now the core engine of all [lindex]
+	operations.
+
+	* generic/tclObj.c (Tcl_AppendAllObjTypes):	Converted to simpler
+	list validity test.
+
+2007-03-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

+
+2007-03-07  Kevin B. Kenny  <kennykb@acm.org>
+
+	* library/clock.tcl: Adjusted Windows time zone table to handle new US

+
+2007-03-03  Donal K. Fellows  <dkf@users.sf.net>
+

+
+2007-03-02  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdIL.c (Tcl_LreverseObjCmd):	Added missing
+	TclInvalidateStringRep() call when we directly manipulate the intrep
+	of an unshared "list" Tcl_Obj. [Bug 1672585]
+
+	* generic/tclCmdIL.c (Tcl_JoinObjCmd):	Revised [join] implementation
+	to append Tcl_Obj's instead of strings. [RFE 1669420]
+
+	* generic/tclCmdIL.c (Info*Cmd):	Code simplifications and
+	optimizations.
+
+2007-03-02  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclCompile.c (TclPrintInstruction): Added a scheme to allow
+	* generic/tclCompile.h (AuxDataPrintProc):    aux-data to be printed
+	* generic/tclCompCmds.c (Print*Info):	      out for debugging. For
+	this to work, immediate operands referring to aux-data must be
+	identified as such in the instruction descriptor table using

+
+	* generic/tclExecute.c (TclExecuteByteCode): Rewrote the compiled
+	* generic/tclCompCmds.c (TclCompileDictCmd): [dict update] so that it
+	* generic/tclCompile.h (DictUpdateInfo):     stores critical
+	* tests/dict.test (dict-21.{14,15}):	     non-varying data in an

+
+	* generic/tclCmdAH.c (Tcl_ForeachObjCmd):	Rewrite to make

+
+2007-03-01  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

+
+2007-02-26  Andreas Kupries  <andreask@activestate.com>
+

+
+2007-02-26  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCmdAH.c (Tcl_ForeachObjCmd):	Removed surplus

+
+2007-02-24  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Use new interface in Tcl_EvalObjEx so that the
+	recounting logic of the List internal rep need not be repeated there.
+	Better encapsulation of internal details.
+
+	* generic/tclInt.h:	New internal routine TclListObjCopy() used
+	* generic/tclListObj.c: to efficiently do the equivalent of [lrange
+	$list 0 end]. After some experience with this, might be a good
+	candidate for exposure as a public interface. It's useful for callers
+	of Tcl_ListObjGetElements() who want to control the ongoing validity
+	of the returned objv pointer.
+
+2007-02-22  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/pkg.test: Added tests for the case of an alpha package

+
+2007-02-13  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tools/fix_tommath_h.tcl: Further tweaking for the x86-64. The change
+	is to make 'mp_digit' be an 'unsigned int' on that platform; since
+	we're using only 32 bits of it, there's no reason to make it a 64-bit

+
+2007-02-12  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tools/fix_tommath_h.tcl: Added code to patch out a check for
+	__x86_64__ that caused Tommath to use __attributes(TI)__ for the
+	mp_word type. Tetra-int's simply fail on too many gcc-glibc-OS
+	combinations to be ready for shipment today, even if they work for

+
+2007-02-04  Daniel Steffen  <das@users.sourceforge.net>

+
+	* generic/tclBasic.c:	 Another step down the path of re-using

+
+	* generic/tclCompExpr.c: Revised implementation of TclInvertOpCmd to

+
+	* tests/mathop.test:	Commmitted several new tests from Peter Spjuth

+
+2006-12-03  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Added expr parsing routines that

+	currently disabled. #undef PARSE_DIRECT_EXPR_TOKENS to enable them.

+	* tests/info.test (info-9.11,info-9.12): Added knownBug constraint

+
+2006-10-28  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclProc.c (ObjInterpProcEx, TclObjInterpProcCore): Split the
+	core of procedures to make it easier to build procedure-like code
+	without going through horrible contortions. This is the last critical
+	component to make advanced OO systems workable as simple loadable
+	extensions. TOIPC is now in the internal stub table.
+	(MakeProcError, MakeLambdaError): Refactored ProcessProcResultCode to
+	be simpler, some of which goes to TclObjInterpProcCore, and the rest
+	of which is now in these far simpler routines which just do errorInfo
+	stack generation for different types of procedure-like entity.

+
+	* generic/tclInt.h (CallFrame): Add a field for handling context data
+	for extensions (like object systems) that should be tied to a call
+	frame (and not a command or interpreter).
+
+	* generic/tclBasic.c (TclRenameCommand): Change to take CONST args;
+	they were only ever used in a constant way anyway, so this appears to
+	be a spot that was missed during TIP#27 work.

+	* generic/tcl.h:	   Lets TEOV update the iPtr->callObj[cv] new
+	* generic/tclBasic.c:	   fields, except when the flag bit

+	* generic/tclNamesp.c:	   are used by Tcl_PushCallFrame to initialise
+	* generic/tclProc.c:	   the frame's obj[cv] fields, and allows
+	* tests/namespace.test:	   [info level] to know and use ensemble
+	rewrites. [Bug 1577492]
+
+	***POTENTIAL INCOMPATIBILITY***
+	The return value from [info level 0] on interp alias calls is changed:

+
+2006-10-23  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tcl.h:	   Modified the Tcl call stack so there is
+	* generic/tclBasic.c:	   always a valid CallFrame, even at level 0
+	* generic/tclCmdIL.c:	   [Patch 1577278]. Most of the changes
+	* generic/tclInt.h:	   involve removing tests for a NULL
+	* generic/tclNamesp.c:	   iPtr->(var)framePtr. There is now a
+	* generic/tclObj.c:	   CallFrame pushed at interp creation with a
+	* generic/tclProc.c:	   pointer to it stored in iPtr->rootFramePtr.
+	* generic/tclTrace.c:	   A second unused field in Interp is
+	* generic/tclVar.c:	   hijacked to enable further functionality,
+	currently unused (but with several FRQs depending on it).
+
+	***POTENTIAL INCOMPATIBILITY***
+	Any user that includes tclInt.h and needs to determine if it is
+	running at level 0 should change (iPtr->varFramePtr == NULL) to
+	(iPtr->varFramePtr == iPtr->rootFramePtr).

+	* generic/tclStubInit.c: added an internal function TclObjBeingDeleted
+	to provide info as to the reason for the loss of an internal rep. [FR
+	1512138]
+
+	* generic/tclCompile.c:
+	* generic/tclHistory.c:
+	* generic/tclInt.h:
+	* generic/tclProc.c: made Tcl_RecordAndEvalObj not call "history" if
+	it has been redefined to an empty proc, in order to reduce the noise
+	when debugging [FR 1190441]. Moved TclCompileNoOp from tclProc.c to
+	tclCompile.c
+
+2006-09-28  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclPkg.c (CompareVersions): Bugfix. Check string lengths
+	* tests/pkg.test: before comparison. The shorter string is the smaller
+	number. Added testcases as well. Interestingly all existing test cases
+	for vcompare compared numbers of the same length with each other. [Bug
+	1563836]
+
+2006-09-28  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclIO.c (Tcl_GetsObj): added two test'n'panic guards for
+	possible NULL derefs, [Bug 1566382] and coverity #33.
+
+2006-09-27  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c: Corrected error in INST_LSHIFT in the
+	* tests/expr.test:	calculation done to determine whether a shift
+	in the (long int) type is possible. The calculation had literal value
+	"1" where it needed a value "1L" to compute the correct result. Error
+	detected via testing with the math::bigfloat package [Bug 1567222]
+
+	* generic/tclPkg.c (CompareVersion):	Flatten strcmp() results to
+	{-1, 0, 1} to match expectations of CompareVersion() callers.
+
+2006-09-27  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/regc_color.c (singleton):
+	* generic/regc_cvec.c (addmcce):
+	* generic/regcomp.c (compile, dovec): the static function addmcce does
+	nothing when called with two NULL pointers; the only call is by
+	compile with two NULL pointers (regcomp.c #includes regc_cvec.c).
+	Large parts (all?) the code for mcce (multi character collating
+	element) that we do not use is ifdef'ed out with the macro
+	REGEXP_MCCE_ENABLE.
+	This silences coverity bugs 7, 16, 80
+
+	* generic/regc_color.c (uncolorchain):
+	* generic/regc_nfa.c (freearc): changed tests and asserts to
+	equivalent formulation, designed to avoid an explicit comparison to
+	NULL and satisfy coverity that 6 and 9 are not bugs.
+
+2006-09-27  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/pkg.test: Added test for version comparison at the 32bit
+	boundary. [Bug 1563836]
+
+	* generic/tclPkg.c: Rewrote CompareVersion to perform string
+	comparison instead of numeric. This breaks through the 32bit limit on
+	version numbers. See code for details (handling of leading zeros,
+	signs, etc.). un-CONSTed some arguments of CompareVersions,
+	RequirementSatisfied, and AllRequirementsSatisfied. The new compare
+	modifies the string (temporary string terminators). All callers use
+	heap-allocated ver-intreps, so we are good with that. [Bug 1563836]
+
+2006-09-27  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclFileName.c (TclGlob): added a panic for a call with
+	TCL_GLOBMODE_TAILS and pathPrefix==NULL. This would cause a segfault,
+	as found by coverity #26.
+
+2006-09-26  Kevin B. Kenny  <kennykb@acm.org>
+
+	* doc/Encoding.3:	 Added covariant 'const' qualifier for the
+	* generic/tcl.decls:	 Tcl_EncodingType argument to
+	* generic/tclEncoding.c: Tcl_CreateEncoding. [Further TIP#27 work.]
+	* generic/tclDecls.h:	 Reran 'make genstubs'.
+
+2006-09-26  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* win/makefile.vc:  Additional compiler flags and amd64 support.
+	* win/nmakehlp.c:
+	* win/rules.vc:
+
+2006-09-26  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tcl.h:	As 2006-09-22 commit from Donal K. Fellows
+	demonstrates, "#define NULL 0" is just wrong, and as a quotable chat
+	figure observed, "If NULL isn't defined, we're not using a C compiler"
+	Improper fallback definition of NULL removed.
+
+2006-09-25  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* generic/tcl.h:	More fixing which struct stat to refer to.
+	* generic/tclGetDate.y: Some casts from time_t to int required.
+	* generic/tclTimer.c:	Tcl_Time structure members are longs.
+	* win/makefile.vc:	Support for varying compiler options
+	* win/rules.vc:		and build to platform-specific subdirs.
+
+2006-09-25  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (Tcl_StackChannel): Fixed [Bug 1564642], aka
+	coverity #51. Extended loop condition, added checking for NULL to
+	prevent seg.fault.
+
+2006-09-25  Andreas Kupries  <andreask@activestate.com>
+
+	* doc/package.n: Fixed nits reported by Daniel Steffen in the TIP#268
+	changes.
+
+2006-09-25  Kevin B. Kenny   <kennykb@acm.org>
+
+	* generic/tclNotify.c (Tcl_DeleteEvents): Simplified the code in hopes
+	of making the invariants clearer and proving to Coverity that the
+	event queue memory is managed correctly.
+
+2006-09-25  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclNotify.c (Tcl_DeleteEvents): Make it clear what happens
+	when the event queue is mismanaged. [Bug 1564677], coverity bug #10.
+
+2006-09-24  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclParse.c (Tcl_ParseCommand): also return an error if
+	start==NULL and numBytes<0. This is coverity's bug #20
+
+	* generic/tclStringObj.c (STRING_SIZE): fix allocation for 0-length
+	strings. This is coverity's bugs #54-5
+
+2006-09-22  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclInt.h: Moved TIP#268's field 'packagePrefer' to the end
+	of the structure, for better backward compatibility.

+
+	* generic/tclExecute.c (INST_EXPON):	Native type overflow detection

+	* unix/configure: Regenerated, using autoconf 2.59
+
+	* unix/tclUnixCompat.c (PadBuffer): Fixed bug in calculation of the

+
+2006-09-11  Pat Thoyts	<patthoyts@users.sourceforge.net>
+
+	* win/rules.vc:	   Updated to install http, tcltest and msgcat as

+	* win/makefile.vc: Added tommath_(super)class headers.
+
+2006-09-11  Andreas Kupries  <andreask@activestate.com>

+
+2006-09-11  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tclUnixCompat.c: make compatLock static and only declare it

+
+2006-09-11  Andreas Kupries  <andreask@activestate.com>

+
+	* unix/Makefile.in:	Bumped msgcat version to 1.4.2 to be

+
+2006-09-10  Daniel Steffen  <das@users.sourceforge.net>
+
+	* library/msgcat/msgcat.tcl (msgcat::Init): on Darwin, add fallback of
+	* tests/msgcat.test:			    default msgcat locale to
+	* unix/tclUnixInit.c (TclpSetVariables):    current CFLocale
+	identifier if available (via private ::tcl::mac::locale global, set at

+
+	* library/tcltest/tcltest.tcl: add 'line' verbose level: prints source
+	* doc/tcltest.n:	       file line information of failing tests.
+
+	* macosx/Tcl.xcodeproj/project.pbxproj: add new tclUnixCompat.c file;

+
+2006-09-08  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>
+
+	* unix/tclUnixCompat.c: Added fallback to gethostbyname() and

+	(currently for Darwin 6 or later only).
+
+	* unix/configure.in: Assume gethostbyname() and gethostbyaddr() are

+
+2006-09-07  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>
+
+	* unix/tclUnixCompat.c: Added fallback to MT-unsafe library calls if

+
+2006-09-07  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

+
+2006-09-04  Jeff Hobbs	<jeffh@ActiveState.com>
+
+	* doc/package.n: correct package example
+
+2006-08-31  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclCompExpr.c:	Corrected flawed logic for disabling
+	the INST_TRY_CVT_TO_NUMERIC instruction at the end of an expression
+	when function arguments contain operators. [Bug 1541274]
+
+	* tests/expr-old.test:	The remaining failing tests reported in
+	* tests/expr.test:	[Bug 1381715] are all new in Tcl 8.5, so
+	there's really no issue of compatibility with Tcl 8.4 result to deal

+
+2006-08-29  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclParseExpr.c:	Use the "parent" field of orphan
+	ExprNodes to store the closure of left pointers. This lets us avoid
+	repeated re-scanning leftward for the left boundary of subexpressions,
+	which in worst case led to near O(N^2) runtime.
+
+2006-08-29  Joe Mistachkin  <joe@mistachkin.com>
+

+	1547786]
+
+	* generic/tclStringObj.c:	Corrected TclFormatObj's failure to

+
+	* library/tzdata: Regenerated, including several new files, from

+	* library/clock.tcl:
+	* tests/clock.test: Removed an early testing hack that allowed loading
+	'registry' from the build tree rather than an installed one. This is a

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

+
+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.
+
+	* 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]

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

+
+	* generic/tclTomMath.h: on Darwin 64-bit, for now disable use of

+
+	* unix/tclUnixInit.c (TclpInitLibraryPath): move code that is only

+
+	* generic/tclLink.c (LinkTraceProc): fix 64-bit signed-with-unsigned
+	comparison warning from gcc4 -Wextra.
+
+	* unix/tclUnixChan.c (TclUnixWaitForFile): with timeout < 0, if

+	1526581]
+
+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
+
+	* tests/compExpr-old.test: add 'oldExprParser' constraint to all tests
+	* tests/compExpr.test:	   that depend on the exact format of the
+	* tests/compile.test:	   error messages of the pre-2006-07-05
+	* tests/expr-old.test:	   expression parser. The constraint is on by
+	* tests/expr.test:	   default (i.e those tests still fail), but
+	* tests/for.test:	   can be turned off by passing '-constraints
+	* tests/if.test:	   newExprParser' to tcltest, which will skip
+	* tests/parseExpr.test:	   the 196 failing tests in the testsuite that
+	* tests/while.test:	   are caused by the new expression parser
+	error messages.
+
+2006-07-31  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclClock.c (ConvertLocalToUTCUsingC): Corrected a regression
+	that caused dates before 1969 to be one day off in the :localtime time
+	zone if TZ is not set. [Bug 1531530]
+
+2006-07-30  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclClock.c (GetJulianDayFromEraYearMonthDay): Corrected
+	several errors in converting dates before the Common Era [Bug 1426279]
+	* library/clock.tcl: Corrected syntax errors in generated code for %EC
+	%Ey, and %W format groups [Bug 1505383]. Corrected a bug in cache
+	management for format strings containing [glob] metacharacters [Bug
+	1494664]. Corrected several errors in formatting/scanning of years
+	prior to the Common Era, and added the missing %EE format group to
+	indicate the era.
+	* tools/makeTestCases.tcl: Added code to make sure that %U and %V
+	format groups are included in the tests. (The code depends on %U and
+	%V formatting working correctly when 'makeTestCases.tcl' is run,
+	rather than making a completely independent check.) Added tests for
+	[glob] metacharacters in strings. Added tests for years prior to the
+	Common Era.
+	* tests/clock.test: Rebuilt with new test cases for all the above.
+
+2006-07-30  Joe English	 <jenglish@users.sourceforge.net>

+
+2006-07-26  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c: Corrected flawed overflow detection in

+
+2006-07-24  Don Porter	<dgp@users.sourceforge.net>

+
+2006-07-21  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclExecute.c:
+	* tests/execute.test (execute-9.1): dgp's fix for [Bug 1522803].
+
+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/tclMacOSXFCmd.c (TclMacOSXCopyFileAttributes):	   add support
+	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier):		   for weakly
+	* unix/tclUnixInit.c (Tcl_GetEncodingNameFromEnvironment): importing
+	symbols not available on OSX 10.2 or 10.3, enables binaires built on
+	later OSX versions to run on earlier ones.
+	* macosx/Tcl.xcodeproj/project.pbxproj: enable weak-linking; turn on
+						extra warnings.
+	* 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; clean up
+	quoting and help messages.
+	* unix/configure: autoconf-2.59

+	* generic/tclStringObj.c (TclAppendFormattedObjs):
+	* 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.
+
+2006-07-05  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclParseExpr.c:	Completely new expression parser that
+	builds a parse tree instead of operating with deep recursion. This
+	corrects reports of stack-blowing crashes parsing long expressions
+	[Bug 906201] and replaces a fundamentally O(N^2) algorithm with an
+	O(N) one [RFE 903765]. The new parser is better able to generate error
+	messages that clearly report both the nature and context of the syntax
+	error [Bugs 1029267, 1381715]. For now, the code for the old parser is
+	still present and can be activated with a "#define OLD_EXPR_PARSER
+	1". This is for the sake of a clean implementation patch, and for ease
+	of benchmarking. The new parser is non-recursive, so much lighter in
+	stack consumption, but it does use more heap, so there may be cases
+	where parsing of long expressions that succeeded with the old parser
+	will lead to out of memory panics with the new one. There are still
+	more improvements possible on that point, though significant progress
+	may require changes to the Tcl_Token specifications documented for the
+	public Tcl_Parse*() routines.
+	***POTENTIAL INCOMPATIBILITY*** for any callers that rely on the exact
+	(usually terrible) error messages generated by the old parser. This
+	includes a large number of tests in the test suite.
+
+	* generic/tclInt.h:		Replaced TclParseWhiteSpace() with
+	* generic/tclParse.c:		TclParseAllWhiteSpace() which is what
+	* generic/tclParseExpr.c:	all the callers really needed.
+	Breaking whitespace runs at newlines is useful only to the command
+	parsing function, and it can call the file scoped routine
+	ParseWhiteSpace() to do that.
+
+	* tests/expr-old.test:	Removed knownBug constraints that masked
+	* tests/expr.test:	failures due to revised error messages.
+	* tests/parseExpr.test:
+
+2006-06-20  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclIOUtil.c:	Changed default configuration to
+	* generic/tclInt.decls: #undef USE_OBSOLETE_FS_HOOKS which disables
+	* generic/tclTest.c:	access to the Tcl 8.3 internal routines for
+	hooking into filesystem operations. Everyone ought to have migrated to
+	Tcl_Filesystems by now.
+	***POTENTIAL INCOMPATIBILITY*** for any code still stuck in the
+	pre-Tcl_Filesystem era.
+
+	* generic/tclIntDecls.h:	make genstubs
+	* generic/tclStubInit.c:
+
+	* generic/tclStrToD.c:	Removed dead code that permitted disabling of
+	recognition of the new 0b and 0o numeric formats.
+
+	* generic/tclExecute.c: Removed dead code that implemented alternative
+	* generic/tclObj.c:	design where numeric values did not
+	automatically narrow to the smallest Tcl_ObjType required to hold them
+
+	* generic/tclCmdAH.c:	Removed dead code that was old implementation
+	of [format].
+
+2006-06-14  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/tclUnixPort.h (Darwin): support 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  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* doc/format.n, doc/scan.n: Added examples for converting between
+	characters and their numeric interpretations following user prompting.
+
+2006-06-13  Donal K. Fellows  <dkf@users.sf.net>
+
+	* 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().
+
+2006-06-05  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* doc/Alloc.3: Added documentation of promise that Tcl_Realloc(NULL,x)
+	is the same as Tcl_Alloc(x), as discussed in comp.lang.tcl. Also fixed
+	nonsense sentence to say something meaningful.
+
+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
+	* unix/tclConfig.h.in: autoheader-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]
+
+2006-05-23  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* doc/chan.n, doc/refchan.n: Tighten up the documentation to follow a
+	slightly more consistent style with regard to argument capitalization.
+
+2006-05-13  Don Porter	<dgp@users.sourceforge.net>
+
+	* 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. Note
+	that the fix will not be effective for code that calls the private
+	routine TclProcCompileProc() directly. [Bug 1482718]
+
+2006-05-13  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclEvent.c (HandleBgErrors): fix leak. [Coverity issue 86]
+
+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]

+	point. Thanks to Bruce Johnson for reporting this bug, originally on
+	http://wiki.tcl.tk/15408.
+	* library/clock.tcl: Fixed a bug with Daylight Saving Time and Posix

+
+2006-04-06  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct):	It seems there

+	same manner as any other key. [Bug 1464039]
+
+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].
+
+2006-03-30  Miguel Sofer  <msofer@users.sf.net>

+	* generic/tclIOGT.c, generic/tclIORChan.c, unix/tclUnixChan.c:
+	* unix/tclUnixPipe.c, win/tclWinChan.c, win/tclWinConsole.c:
+	* win/tclWinPipe.c, win/tclWinSerial.c, win/tclWinSock.c:
+
+2006-03-27  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c: Merge INST_MOD computation in with the
+	INST_?SHIFT instructions, which also operate only on two integral
+	values. Also corrected flaw that made INST_BITNOT of wide values
+	require mp_int calculations. Also corrected type that missed optimized
+	handling of the tclBooleanType by the TclGetBooleanFromObj macro.
+
+	* changes:	Updates for another RC.
+
+2006-03-25  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c: Corrections to INST_EXPON detection of
+	overflow to use mp_int calculations.
+
+2006-03-24  Kevin B. Kenny  <kennykb@acm.org>
+
+	* generic/tclExecute.c (TclExecuteByteCode): Added a couple of missing
+	casts to 'int' that were affecting compilablity on VC6.
+
+2006-03-24  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclEncoding.c: Reverted latest change [Bug 506653] since it
+	reportedly killed test performance on Windows.
+
+	* generic/tclExecute.c: Revised INST_EXPON implementation to do
+	calculations in native types as much as possible, moving to mp_ints
+	only when necessary.
+
+2006-03-23  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c: Merged INST_EXPON handling in with the other
+	binary operators that operate on all number types (INST_ADD, etc.).
+
+	* tests/env.test: With case preserved (see 2006-03-21 commit) be sure
+	to do case-insensitive filtering. [Bug 1457065]
+
+2006-03-23  Reinhard Max  <max@suse.de>
+
+	* unix/tcl.spec: Cleaned up and completed the spec file. An RPM can
+	now be built from the tcl source distribution with "rpmbuild -tb
+	<tarball>"
+
+2006-03-22  Reinhard Max  <max@suse.de>
+
+	* tests/stack.test: Run the stack tests in subshells, so that they are
+	reported as failed tests rather than bugs in the test suite if the
+	recursion causes a segfault.
+
+2006-03-21  Don Porter	<dgp@users.sourceforge.net>
+
+	* changes:	Updates for another RC.
+
+	* generic/tclStrToD.c:	One of the branches of AccumulateDecimalDigit
+	* tests/parseExpr.test: did not. [Bug 1451233]
+
+	* tests/env.test:	Preserve case of saved env vars. [Bug 1409272]
+
+2006-03-21  Daniel Steffen  <das@users.sourceforge.net>
+
+	* generic/tclInt.decls:	 implement globbing for HFS creator & type
+	* macosx/tclMacOSXFCmd.c:codes and 'hidden' flag, as documented in
+	* tests/macOSXFCmd.test: glob.n; objectified OSType handling in [glob]
+	* unix/tclUnixFile.c:	 and [file attributes]; fix globbing for
+	hidden files with pattern==NULL arg. [Bug 823329]
+	* generic/tclIntPlatDecls.h:
+	* generic/tclStubInit.c: make genstubs
+
+2006-03-20  Andreas Kupries <andreask@activestate.com>
+
+	* win/Makefile.in (install-libraries): Generate tcl8/8.4 directory
+	under Windows as well (cygwin Makefile). Related entry: 2006-03-07,
+	dgp. This moved the installation of http from 8.2 to 8.4, partially. A
+	fix of the required directory creation was done for unix on Mar 10,
+	without entry in the Changelog. This entry is for the fix of the
+	directory creation under Windows.
+
+	* unix/installManPage: There is always one even more broken "sed".
+	Moved the # comment starting character in the sed script to the
+	beginning of their respective lines. The AIX sed will not recognize
+	them as comments otherwise :( The actual text stays indented for
+	better association with the commands they belong to.
+
+2006-03-20  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* tests/cmdAH.test, tests/fCmd.test, tests/unixFCmd.test:
+	* tests/winFCmd.test: Cleanup of some test constraint handling, and a
+	few other minor issues.
+
+2006-03-18  Vince Darley  <vincentdarley@sourceforge.net>
+
+	* generic/tclFileName.c:
+	* doc/FileSystem.3:
+	* tests/fileName.test: Fix to [Bug 1084705] so that 'glob -nocomplain'
+	finally agrees with its documentation and doesn't swallow genuine
+	errors.
+
+	***POTENTIAL INCOMPATIBILITY*** for scripts that assumed '-nocomplain'
+	removes the need for 'catch' to deal with non-understood path names.
+
+	Small optimisation to implementation of pattern==NULL case of TclGlob,
+	and clarification to the documentation. [Tclvfs bug 1405317]
+
+2006-03-18  Vince Darley  <vincentdarley@sourceforge.net>
+
+	* tests/fCmd.test: added knownBug test case for [Bug 1394972]
+
+	* tests/winFCmd.test:
+	* tests/tcltest.test: corrected tests to better account for behaviour
+	of writable/non-writable directories on Windows 2000/XP. This, with
+	the previous patches, closes [Bug 1193497]
+
+2006-03-17  Andreas Kupries <andreask@activestate.com>
+
+	* doc/chan.n: Updated with documentation for the commands 'chan
+	create' and 'chan postevent' (TIP #219).
+
+	* doc/refchan.n: New file. Documentation of the command handler API
+	for reflected channels (TIP #219).
+
+2006-03-17  Joe Mistachkin <joe@mistachkin.com>
+
+	* unix/tclUnixPort.h: Include pthread.h prior to pthread_np.h [Bug
+	1444692]
+
+	* win/tclWinTest.c: Corrected typo of 'initializeMutex' that prevented
+	successful compilation.
+
+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]
+
+2006-03-15  Vince Darley  <vincentdarley@sourceforge.net>
+
+	* win/fCmd.test: add proper test constraints so the new tests don't
+	run on Unix.
+
+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>
+
+	* doc/clock.n: Removed double-quotes around section title NAME; not
+	needed.
+	* unix/installManpage: Reverted part to handle double-quotes in
+	section NAME, chokes older sed installations.
+
+2006-03-14  Andreas Kupries <andreask@activestate.com>
+
+	* library/tm.tcl (::tcl::tm::Defaults): Fixed handling of environment
+	variable TCLX.y_TM_PATH, bad variable reference. Thanks to Julian
+	Noble. [Bug 1448251]
+
+2006-03-14  Vince Darley  <vincentdarley@sourceforge.net>
+
+	* win/tclWinFile.c: updated patch to deal with 'file writable' issues
+	on Windows XP/2000.
+	* generic/tclTest.c:
+	* unix/tclUnixTest.c:
+	* win/tclWinTest.c:
+	* tests/fCmd.test: updated test suite to deal with correct permissions
+	setting and differences between XP/2000 and 95/98 3 tests still fail;
+	to be dealt with shortly
+
+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-2.59.
+
+2006-03-10  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclProc.c (ObjInterpProcEx):
+	* tests/apply.test (apply-5.1): Fix [apply] error messages so that
+	they quote the lambda expression. [Bug 1447355]
+
+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.c: Added no-op TclpFinalizeSockets().
+
+	* win/tclWinPipe.c, win/tclWinSock.c: Finalization of 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/tclWinFile.c: previous patch breaks tests, so removed.

+
+	* changes:	Update in prep. for 8.5a4 release.
+
+	* unix/Makefile.in:	Package http 2.5.2 requires Tcl 8.4, so the
+	* win/Makefile.in:	*.tm installation has to be placed in an "8.4"

+
+	* generic/tclBasic.c:	Revised handling of TCL_EVAL_* flags to

+
+2006-03-03  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclPathObj.c: Revised yesterday's fix for [Bug 1379287] to
+	work on Windows.
+
+	* generic/tclObj.c:	Compatibility support for existing code that
+	calls Tcl_GetObjType("boolean").
+
+2006-03-02  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclPathObj.c:		Fix for failed normalization of paths
+	* tests/fileSystem.test:	with /../ that lead back to the root
+	of the filesystem, like /foo/.. [Bug 1379287]
+
+2006-03-01  Reinhard Max  <max@suse.de>
+
+	* unix/installManPage: Fix the script for manpages that have quotes
+	around the .SH arguments, as doctools produces them. [Bug 1292145]
+	Some minor cleanups and improvements.
+
+2006-02-28  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Corrections to be sure that TCL_EVAL_GLOBAL
+	* tests/namespace.test: evaluations act the same as [uplevel #0]
+	* tests/parse.test:	evaluations, even when execution traces or
+	* tests/trace.test:	invocations of [::unknown] are present. [Bug
+	1439836]
+
+2006-02-22  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Corrected a few bugs in how [namespace

+	[Patch 958222]
+
+2006-02-17  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclIORChan.c: Revised error message generation and handling
+	* tests/ioCmd.test:	of exceptional return codes in the channel
+	reflection layer. [Bug 1372348]
+
+2006-02-16  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclIndexObj.c:	Disallow the "ambiguous" error message
+	* tests/indexObj.test:		when TCL_EXACT matching is requested.
+	* tests/ioCmd.test:
+
+2006-02-15  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclIO.c:	Made several routines tolerant of
+	* generic/tclIORChan.c: interp == NULL arguments. [Bug 1380662]
+	* generic/tclIOUtil.c:
+
+2006-02-09  Don Porter	<dgp@users.sourceforge.net>
+
+	TIP#215 IMPLEMENTATION
+
+	* doc/incr.n:		Revised [incr] to auto-initialize when varName
+	* generic/tclExecute.c: argument is unset. [Patch 1413115]
+	* generic/tclVar.c:
+	* tests/compile.test:
+	* tests/incr-old.test:
+	* tests/incr.test:
+	* tests/set.test:

+	Don Porter. Mostly minor changes.
+
+2006-02-08  Don Porter	<dgp@users.sourceforge.net>
+
+	TIP#258 IMPLEMENTATION
+
+	* doc/Encoding.3:	New subcommand [encoding dirs].
+	* doc/encoding.n:	New routine Tcl_GetEncodingNameFromEnvironment
+	* generic/tcl.decls:	Made public:

+	* generic/tclStubInit.c:
+
+2006-02-01  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclProc.c: minor improvements to [apply]
+	* tests/apply.test: new tests; apply-5.1 currently fails to indicate

+2006-02-01  Don Porter	<dgp@users.sourceforge.net>
+
+	TIP#194 IMPLEMENTATION

+
+2006-01-26  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* unix/tclUnixChan.c (TclpOpenFileChannel): Tidy up and comment the
+	mess to do with setting up serial channels. This (deliberately) breaks
+	a broken FreeBSD port, indicates what we're really doing, and reduces
+	the amount of conditional compilation sections for better maintenance.
+
+2006-01-25  Donal K. Fellows  <dkf@users.sf.net>
+
+	* unix/tclUnixInit.c (TclpInitPlatform): Improved conditions on when
+	to update the FP rounding mode on FreeBSD, taken from FreeBSD port.

+	* tests/string.test (string-12.21): Added test for [Bug 1410553] based
+	on original bug report.
+
+2006-01-23  Miguel Sofer  <msofer@users.sf.net>

+	* generic/tclStringObj.c: fixed incorrect handling of internal rep in
+	Tcl_GetRange. Thanks to twylite and Peter Spjuth. [Bug 1410553]
+
+	* generic/tclProc.c: fixed args handling for precompiled bodies [Bug
+	1412695]; thanks to Uwe Traum.
+
+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/tclPathObj.c (Tcl_FSGetInternalRep): backported patch from
+	core-8-4-branch. A freed pointer has been overwritten causing all
+	sorts of coredumps.
+
+2006-01-12  Vince Darley  <vincentdarley@sourceforge.net>
+
+	* win/tclWinFile.c: fix to sharing violation [Bug 1366227]
+
+2006-01-11  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c:	Moved Tcl_LogCommandInfo from tclBasic.c to
+	* generic/tclNamesp.c:	tclNamesp.c to get access to identifier with
+	* tests/error.test (error-7.0): file scope. Added check for traces on
+	::errorInfo, and when present fall back to contruction of the stack
+	trace in the variable so that write trace notification timings are
+	compatible with earlier Tcl releases. This reduces, but does not
+	completely eliminate the ***POTENTIAL INCOMPATIBILITY*** created by
+	the 2004-10-15 commit. [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 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]
+
+2006-01-09  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* generic/tclTrace.c: Stop exporting the guts of the trace command;
+	nothing outside this file needs to see it. [Bug 971336]
+
+2006-01-05  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>
+
+	* unix/tcl.m4 (TCL_CONFIG_SYSTEM): Factor out the code to determine
+	the operating system version number, as it was replicated in several
+	places.
+
+2006-01-04  David Gravereaux  <davygrvy@pobox.com>
+
+	* win/tclAppInit.c: WIN32 native console signal handler removed. This
+	was found to be interfering with TWAPI extension one. IMO, special
+	services such as signal handlers should best be done with extensions
+	to the core after discussions on c.l.t. about Roy Terry's tclsh
+	children of a real windows service shell.

+	out of the eval-direct code path to be done always, i.e. even when a

+	* tests/info.test: more sensible to have everything on line 1 when
+	eval'ing a pure list. Updated the users of the line information to

+	* generic/tclCompile.h: recursion, replaced the linear search through
+	* generic/tclExecute.c: the whole stack with another hashtable and

+
+2008-06-24  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclPathObj.c: Fixed some internals management in the "path"

+
+2008-06-23  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclPathObj.c: Fixed bug in Tcl_GetTranslatedPath() when
+	operating on the "Special path" variant of the "path" Tcl_ObjType
+	intrep. A full normalization was getting done, in particular, coercing
+	relative paths to absolute, contrary to what the function of producing

+
+2008-06-19  Don Porter  <dgp@users.sourceforge.net>
+

+

+2008-06-17  Andreas Kupries  <andreask@activestate.com>
+
+	* doc/tm.n: Followup to changelog entry 2008-03-18 regarding

+	encouraged form as well. [Bug 1914604]
+
+2008-06-17  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclClock.c (ConvertLocalToUTC):
+	* tests/clock.test (clock-63.1): Fixed a bug where the internal
+	ConvertLocalToUTC command segfaulted if passed a dictionary without
+	the 'localSeconds' key. To the best of my knowledge, the bug was not
+	observable in the [clock] command itself.
+
+2008-06-16  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclCmdIL.c (TclInfoFrame): Backport of fix made on the
+	* tests/info.test: head branch :: Moved the code looking up the
+	information for key 'proc' out of the TCL_LOCATION_BC branch to
+	after the switch, this is common to all frame types. Updated the
+	testsuite to match. This was exposed by the 2008-06-08 commit

+	[Bug 1987851].
+
+2008-06-12  Daniel Steffen  <das@users.sourceforge.net>
+
+	* unix/Makefile.in:		Add complete deps on tclDTrace.h.

+	* tests/io.test (io-53.9): Need to close chan before removing file.
+
+2008-05-23  Andreas Kupries  <andreask@activestate.com>
+
+	* win/tclWinChan.c (FileWideSeekProc): Accepted a patch by Alexandre
+	Ferrieux <ferrieux@users.sourceforge.net> to fix the [Bug 1965787].
+	'tell' now works for locations > 2 GB as well instead of going
+	negative.
+
+	* generic/tclIO.c (Tcl_SetChannelBufferSize): Accepted a patch by
+	* tests/io.test: Alexandre Ferrieux <ferrieux@users.sourceforge.net>
+	* tests/chanio.test: to fix the [Bug 1969953]. Buffersize outside of
+	the supported range are now clipped to nearest boundary instead of

+
+2008-05-22  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclNamesp.c (Tcl_LogCommandInfo):	Restored ability to

+	discovering the bug and providing the fix. [Bug 1968245]
+
+2008-05-21  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclParse.c (ParseComment):	The new TclParseAllWhiteSpace
+	* tests/parse.test (parse-15.60):	routine has no mechanism to
+	return the "incomplete" status of "\\\n" so calling this routine
+	anywhere that can be reached within a Tcl_ParseCommand() call is a
+	mistake. In particular, ParseComment() must not use it. [Bug 1968882]
+
+2008-05-21  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclNamesp.c (Tcl_SetNamespaceUnknownHandler): Corrected odd
+	logic for handling installation of namespace unknown handlers which
+	could lead too very strange things happening in the error case.
+
+2008-05-16  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclCompile.c: Fix crash with tcl_traceExec. Found and fixed
+	by Alexander Pasadyn. [Bug 1964803]
+
+2008-05-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* generic/tclCompCmds.c (TclCompileDictAppendCmd): Fix silly off-by
+	one error that caused a crash every time a compiled 'dict append' with
+	more than one argument was used. Found by Colin McCormack.
+
+2008-04-26  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>
+
+	* generic/tclAsync.c: Tcl_AsyncDelete(): panic if attempt to locate
+	handler token fails. Happens when some other thread attempts to delete
+	somebody else's token.
+
+	Also, panic early if we find out the wrong thread attempting to delete
+	the async handler (common trap). As, only the one that created the
+	handler is allowed to delete it.
+
+2008-04-24  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/ioCmd.test: Extended testsuite for reflected channel
+	implementation. Added test cases about how it handles if the rug is
+	pulled out from under a channel (= killing threads, interpreters
+	containing the tcl command for a channel, and channel sitting in a
+	different interpreter/thread.)
+
+	* generic/tclIORChan.c: Fixed the bugs exposed by the new testcases,
+	redone most of the cleanup and exit handling.
+
+2008-04-15  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (CopyData):	Applied another patch by Alexandre
+	* io.test (io-53.8a):		Ferrieux <ferrieux@users.sf.net>,
+	* chanio.test (chan-io-53.8a):	to shift EOF handling to the async
+	part of the command if a callback is specified, should the channel be
+	at EOF already when fcopy is called. Testcase by myself.
+
+2008-04-14  Kevin B. Kenny  <kennykb@acm.org>
+
+	* unix/tclUnixTime.c (NativeGetTime): Removed obsolete use of
+	'struct timezone' in the call to 'gettimeofday'. [Bug 1942197]
+
+	* tests/clock.test (clock-33.5, clock-33.5a, clock-33.8, clock-33.8a):
+	Added comments to the test that it can fail on a heavily loaded
+	system.
+
+2008-04-11  Don Porter	<dgp@users.sourceforge.net>
+
+	* generic/tcl.h:	Bump version number to 8.5.3b1 to distinguish

+2008-04-10  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Keeping check for negative
+	values, changed to not be an error, but behave like the special value
+	-1 (copy all, default).
+
+	* tests/iocmd.test (iocmd-15.{12,13}): Removed.
+
+	* tests/io.test (io-52.5{,a,b}): Reverted last change, added
+	* tests/chanio.test (chan-io-52.5{,a,b}): comment regarding the
+	meaning of -1, added two more testcases for other negative values,
+	and input wrapped to negative.
+
+2008-04-09  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/chanio.test (chan-io-52.5): Removed '-size -1' from test,
+	* tests/io.test (io-52.5): does not seem to have any bearing, and was
+	an illegal value.
+
+	* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Added checking of -size value
+	* tests/ioCmd.test (iocmd-15.{13,14}): to reject negative values, and
+	values overflowing 32-bit signed. Basic patch by Alexandre Ferrieux
+	<ferrieux@users.sourceforge.net>, with modifications from me to
+	separate overflow from true negative value. Extended testsuite. [Bug
+	1557855]
+
+2008-04-08  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/io.test (io-53.8): Fixed ordering of vwait and after
+	cancel. cancel has to be done after the vwait completes.
+
+2008-04-09  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tests/chanio.test (chan-io-53.8,53.9,53.10):	fix typo & quoting for
+	* tests/io.test (io-53.8,53.9,53.10):		spaces in builddir path
+
+2008-04-07  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/io.test (io-53.10): Testcase for bi-directionaly fcopy.
+	* tests/chanio.test:
+	* generic/tclIO.c: Additional changes to data structures for fcopy
+	* generic/tclIO.h: and channels to perform proper cleanup in case
+	of a channel having two background copy operations running as is
+	now possible.
+
+	* tests/io.test (io-53.10): Testcase for bi-directionaly fcopy.
+	* generic/tclIO.c: Additional changes to data structures for fcopy
+	and channels to perform proper cleanup in case of a channel having
+	two background copy operations running as is now possible.
+
+2008-04-07  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (BUSY_STATE, CheckChannelErrors,
+	TclCopyChannel): New macro, and the places using it. This change
+	allows for bi-directional fcopy on channels. [Bug 1350564]. Thanks
+	to Alexandre Ferrieux <ferrieux@users.sourceforge.net> for the
+	patch.
+
+2008-04-07  Reinhard Max  <max@suse.de>
+
+	* generic/tclStringObj.c (Tcl_AppendFormatToObj): Fix [format {% d}]
+	so that it behaves the same way as in 8.4 and as C's printf().
+	* tests/format.test: Add a test for '% d' and '%+d'.
+
+2008-04-05  Kevin B. Kenny  <kennykb@acm.org>
+
+	* tests/chanio.test (chan-io-53.9):
+	* tests/io.test (io-53.9): Made test cleanup robust against the
+	possibility of slow process shutdown on Windows.
+
+	* win/tcl.m4: Added -D_CRT_SECURE_NO_DEPRECATE and
+	-DCRT_NONSTDC_NO_DEPRECATE to the MSVC compilation flags so that the
+	compilation doesn't barf on perfectly reasonable Posix system calls.
+	* win/configure: Manually patched (don't have the right autoconf to
+	hand).
+
+	* win/tclWinFile.c: (WinSymLinkDirectory): Fixed a problem that
+	Tcl was creating an NTFS junction point (IO_REPARSE_TAG_MOUNT_POINT)
+	but filling in the union member for a Vista symbolic link. We had
+	gotten away with this error because the union member
+	(SymbolicLinkReparseBuffer) was misdefined in this file and in the
+	'winnt.h' in early versions of MinGW. MinGW 3.4.2 has the correct
+	definition of SymbolicLinkReparseBuffer, exposing the mismatch,
+	and making tests cmdAH-19.4.1, fCmd-28.*, and filename-11.* fail.
+
+2008-04-04  Andreas Kupries  <andreask@activestate.com>
+
+	* tests/io.test (io-53.9): Added testcase for [Bug 780533], based
+	* tests/chanio.test: on Alexandre's test script. Also fixed problem
+	with timer in preceding test, was not canceled properly in the ok case
+
+2008-04-04  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIORChan.c (ReflectOutput): Allow zero return from write
+	when input was zero-length anyway. Otherwise keept it an error, and
+	separate the message from 'written too much'.
+
+	* tests/ioCmd.test (iocmd-24.6): Testcase updated for changed message.
+
+	* generic/tclIORChan.c (ReflectClose): Added missing removal of the
+	now closed channel from the reflection map. Before we could crash the
+	system by invoking 'chan postevent' on a closed reflected channel,
+	dereferencing the dangling pointer in the map.
+
+	* tests/ioCmd.test (iocmd-31.8): Testcase for the above.
+
+2008-04-03  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (CopyData): Applied patch [Bug 1932639] to
+	* tests/io.test: prevent fcopy from calling -command synchronously
+	* tests/chanio.test: the first time. Thanks to Alexandre Ferrieux
+	<ferrieux@users.sourceforge.net> for report and patch.
+
+2008-04-02  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclIO.c (CopyData): Applied patch for fcopy problem [Bug
+	780533], with many thanks to Alexandre Ferrieux
+	<ferrieux@users.sourceforge.net> for tracking it down and providing a
+	solution. Still have to convert his test script into a proper test
+	case.
+
+2008-04-01  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclStrToD.c: Applied patch for [Bug 1839067] (fp rounding
+	* unix/tcl.m4:	       setup on solaris x86, native cc), provided by
+	* unix/configure:      Michael Schlenker. configure regen'd.
+
+2008-04-01  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclStubLib.c (Tcl_InitStubs):	Added missing error message.
+	* generic/tclPkg.c (Tcl_PkgInitStubsCheck):
+
+2008-03-30  Kevin Kenny  <kennykb@acm.org>
+
+	* generic/tclInt.h (TclIsNaN):
+	* unix/configure.in: Added code to the configurator to check for a
+			     standard isnan() macro and use it if one is
+			     found. This change avoids bugs where the test of
+			     ((d) != (d)) is optimized away by an
+			     overaggressive compiler. [Bug 1783544]
+	* generic/tclObj.c: Added missing #include <math.h> needed to locate
+			    isnan() after the above change.
+
+	* unix/configure: autoconf-2.61
+
+	* tests/mathop.test (mathop-25.9, mathop-25.14): Modified tests to
+	deal with (slightly buggy) math libraries in which pow() returns an
+	incorrectly rounded result. [Bug 1808174]
+
+2008-03-26  Don Porter  <dgp@users.sourceforge.net>

+

+
+2008-03-21  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/switch.n: Clarified documentation in respect of two-argument
+	invokation. [Bug 1899962]
+

+
+2008-03-20  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tcl.h, generic/tclThreadAlloc.c: Tidied up the declarations
+	of Tcl_GetMemoryInfo so that it is always defined. Will panic when
+	called against a Tcl that was previously built without it at all,
+	which is OK because that also indicates a serious mismatch between
+	memory configuration options.
+
+2008-03-19  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tcl.h, generic/tclThreadAlloc.c (Tcl_GetMemoryInfo): Make
+	sure this function is available when direct linking. [Bug 1868171]
+
+	* tests/reg.test (reg-33.14): Marked nonPortable because some
+	environments have small default stack sizes. [Bug 1905562]
+
+2008-03-18  Andreas Kupries  <andreask@activestate.com>
+
+	* library/tm.tcl (::tcl::tm::UnknownHandler): Changed 'source' to
+	'source -encoding utf-8'. This fixes a portability problem of Tcl
+	Modules pointed out by Don Porter. By using plain 'source' we were at
+	the mercy of 'encoding system', making modules less portable than they
+	could be. The exact scenario: A writes a TM in some weird encoding
+	which is A's system encoding, distributes it, and somewhere else it
+	cannot be read/used because the system encoding is different. Forcing
+	the use of utf-8 makes the module portable.
+
+	***INCOMPATIBILITY*** for all Tcl Modules already written in non-utf-8
+	compatible encodings.
+
+2008-03-18  Don Porter  <dgp@users.sourceforge.net>

+
+2008-03-18  Andreas Kupries  <andreask@activestate.com>
+
+	* library/tm.tcl (::tcl::tm::Defaults): Modified handling of
+	environment variables. Solution slightly different than proposed in
+	the report. Using the underscored form TCLX_y_TM_PATH even if
+	TCLX.y_TM_PATH exists. Also using a loop to cut prevent code
+	replication. [Bug 1914604]
+
+2008-03-16  Donal K. Fellows  <dkf@users.sf.net>
+
+	* generic/tclCompCmds.c (TclCompileDictForCmd): Correct the handling
+	of stack space calculation (the jump pattern used was confusing the
+	simple-minded code doing the calculations). [Bug 1903325]
+
+	* doc/lreplace.n: Clarified documentation of what happens with
+	negative indices. [Bug 1905809] Added example, tidied up formatting.
+
+2008-03-14  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c (OldMathFuncProc):	Same workaround protection
+	from bad TclStackAlloc() alignment. Thanks George Peter Staplin.
+
+	* generic/tclCmdIL.c (Tcl_LsortObjCmd):	Use ckalloc() to allocate
+	SortElement arrays instead of TclStackAlloc() which isn't getting

+
+2008-03-14  Reinhard Max  <max@suse.de>

+
+	* macosx/Tcl.xcodeproj/project.pbxproj:	Add support for Xcode 3.1 and
+	* macosx/Tcl.xcodeproj/default.pbxuser:	configs for building with

+
+2008-03-11  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclVar.c (TclDeleteNamespaceVars):
+	* tests/var.test (var-8.2): Unset traces on vars should be called with
+	a FQ named during namespace deletion. This was causing infinite loops
+	when unset traces recreated the var, as reported by Julian Noble. [Bug
+	1911919]
+
+2008-03-10  Don Porter  <dgp@users.sourceforge.net>
+
+	* changes:		Updated for 8.5.2 release.
+
+	* doc/http.n:	Revised to indicate that [package require http 2.5.5]
+	is needed to get all the documented commands ([http::meta]).
+
+	* generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd):	Added error
+	* tests/event.test (event-5.*):	checking to protect against callers
+	passing invalid return options dictionaries. [Bug 1901113]
+
+	* generic/tclBasic.c (ExprAbsFunc):	Revised so that the abs()
+	* tests/expr.test:	function and the [::tcl::mathfunc::abs]
+	command do not return the value of -0, or equivalent values with more
+	alarming string reps like -1e-350. [Bug 1893815]
+
+2008-03-07  Andreas Kupries  <andreask@activestate.com>
+
+	* generic/tclResult.c (ReleaseKeys): Workaround for [Bug 1904907].
+	Reset the return option keys to NULL to allow full re-initialization
+	by GetKeys(). This introduces a memory leak for the key objects, but
+	gets us around a crash in the finalization of reflected channels when
+	handling returns, either at compile- or runtime. In both cases we
+	access the keys after they have been released by their thread exit
+	handler. A proper fix is entangled with the untangling of the
+	finalization ordering and attendant issues. For now we choose the
+	lesser evil.
+
+2008-03-07  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclExecute.c (Tcl_ExprObj):	Revised expression bytecode
+	compiling so that bytecodes invalid due to changing context or due to
+	the difference between expressions and scripts are not reused. [Bug
+	1899164]
+
+	* generic/tclCmdAH.c:	Revised direct evaluation implementation of
+	[expr] so that [expr $e] caches compiled bytecodes for the expression
+	as the intrep of $e.
+
+	* tests/execute.test (execute-6.*):	More tests checking that
+	script bytecode is invalidated in the right situations.
+
+2008-03-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>
+
+	* win/configure.in: Add AC_HEADER_STDC to support msys/win64.
+
+2008-03-06  Donal K. Fellows  <dkf@users.sf.net>
+
+	* doc/namespace.n: Minor tidying up. [Bug 1909019]
+
+2008-03-04  Don Porter  <dgp@users.sourceforge.net>
+
+	* tests/execute.test (6.3,4):	Added tests for [Bug 1899164].
+
+2008-03-03  Reinhard Max  <max@suse.de>
+
+	* unix/tclUnixChan.c: Fix mark and space parity on Linux, which uses
+	CMSPAR instead of PAREXT.
+
+2008-03-02  Miguel Sofer  <msofer@users.sf.net>
+
+	* generic/tclNamesp.c (GetNamespaceFromObj):
+	* tests/interp.test (interp-28.2): Spoil the intrep of an nsNameType
+	obj when the reference crosses interpreter boundaries.
+
+2008-02-29  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclResult.c (Tcl_SetReturnOptions):	Revised the refcount
+	management of Tcl_SetReturnOptions to become that of a conventional
+	Consumer routine. Thanks to Peter Spjuth for pointing out the
+	difficulties calling Tcl_SetReturnOptions with non-0-count value for
+	options.
+	* generic/tclExecute.c (INST_RETURN_STK): Revised the one caller
+	within Tcl itself which passes a non-0-count value to
+	Tcl_SetReturnOptions().
+
+	* generic/tclBasic.c (Tcl_AppendObjToErrorInfo):	Revised the
+	refcount management of Tcl_AppendObjToErrorInfo to become that of a
+	conventional Consumer routine. This preserves the ease of use for the
+	overwhelming common callers who pass in a 0-count value, but makes the
+	proper call with a non-0-count value less surprising.
+	* generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd):	Revised the
+	one caller within Tcl itself which passes a non-0-count value to
+	Tcl_AppendObjToErrorInfo().
+
+2008-02-28  Joe English  <jenglish@users.sourceforge.net>
+
+	* unix/tclPort.h, unix/tclCompat.h, unix/tclUnixChan.h: Reduce scope
+	of <sys/filio.h> and <sys/ioctl.h> #includes. [Patch 1903339]
+
+2008-02-28  Joe English  <jenglish@users.sourceforge.net>
+
+	* unix/tclUnixChan.c, unix/tclUnixNotfy.c, unix/tclUnixPipe.c:
+	Consolidate all code conditionalized on -DUSE_FIONBIO into one place.
+	* unix/tclUnixPort.h, unix/tclUnixCompat.c: New routine
+	TclUnixSetBlockingMode(). [Patch 1903339]
+
+2008-02-28  Don Porter  <dgp@users.sourceforge.net>
+
+	* generic/tclBasic.c (TclEvalObjvInternal):	Plug memory leak when
+	an enter trace deletes or changes the command, prompting a reparsing.
+	Don't let the second pass lose commandPtr value allocated during the
+	first pass.
+
+	* generic/tclCompExpr.c (ParseExpr):	Plug memory leak in error
+	message generation.
+
+	* generic/tclStringObj.c (Tcl_AppendFormatToObj): [format %llx $big]
+	leaked an mp_int.
+
+	* generic/tclCompCmds.c (TclCompileReturnCmd):	The 2007-10-18 commit
+	to optimize compiled [return -level 0 $x] [RFE 1794073] introduced a
+	memory leak of the return options dictionary. Fixing that.
+
+2008-02-27  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* library/http/http.tcl: [Bug 705956] - fix inverted logic when
+	cleaning up socket error in geturl.
+
+2008-02-27  Kevin B. Kenny  <kennykb@acm.org>

+	* doc/clock.n: Corrected minor indentation gaffe in the penultimate
+	paragraph. [Bug 1898025]
+	* generic/tclClock.c (ParseClockFormatArgs): Changed to check that the
+	clock value is in the range of a 64-bit integer. [Bug 1862555]
+	* library/clock.tcl (::tcl::clock::format, ::tcl::clock::scan,
+	(::tcl::clock::add, ::tcl::clock::LocalizeFormat): Fixed bugs in
+	caching of localized strings that caused weird results when localized
+	date/time formats were used. [Bug 1902423]
+	* tests/clock.test (clock-61.*, clock-62.1): Regression tests for [Bug
+	1862555] and [Bug 1902423].
+
+2008-02-26  Joe English  <jenglish@users.sourceforge.net>
+
+	* generic/tclIOUtil.c, unix/tclUnixPort.h, unix/tclUnixChan.c:
+	Remove dead/unused portability-related #defines and unused conditional
+	code. See [Patch 1901828] for discussion.
+
+2008-02-26  Joe English  <jenglish@users.sourceforge.net>
+
+	* generic/tclIORChan.c (enum MethodName),
+	* generic/tclCompExpr.c (enum Marks): More stray trailing ","s
+
+2008-02-26  Joe English  <jenglish@users.sourceforge.net>
+
+	* unix/configure.in(socklen_t test): Define socklen_t as "int" if
+	missing, not "unsigned". Use AC_TRY_COMPILE instead of
+	AC_EGREP_HEADER.
+	* unix/configure: regenerated.
+
+2008-02-26  Joe English  <jenglish@users.sourceforge.net>
+

+
+	* library/http/pkgIndex.tcl: Set version 2.5.5
+	* library/http/http.tcl:     It is better to do the [eof] check after
+	trying to read from the socket. No clashes found in testing. Added
+	http::meta command to access the http headers. [Bug 1868845]
+
+2008-02-22  Pat Thoyts  <patthoyts@users.sourceforge.net>
+
+	* library/http/pkgIndex.tcl: Set version 2.5.4

+	* generic/tclClock.c (ClockParseformatargsObjCmd):
+	* library/clock.tcl (::tcl::clock::format):
+	* tests/clock.test (clock-1.0, clock-1.4):
+	Performance enhancements in [clock format] (moving the analysis of
+	$args into C code, holding on to Tcl_Objs with resolved command names,
+	[lassign] in place of [foreach], avoiding [namespace which] for
+	command resolution).

Subject: Backport 8.6's fix [checkin 5af0d249de] to [Bug 2901998]:
 Inconsistent buffered I/O. Tcl's I/O now flushes buffered output before
 reading, discards buffered input before writing, etc.

Subject: Add support for Cygwin64, which has a 64-bit "long" type. Binary
 compatibility with win64 requires that all stub entries use 32-bit long's,
 therefore the	need for various wrapper functions/macros. For Tcl 9 a better
 solution is needed, but that cannot be done without introducing binary
 incompatibility.

+.SH NAME
+miniunzip - uncompress and examine ZIP archives
+.SH SYNOPSIS
+.B miniunzip
+.RI [ -exvlo ]
+zipfile [ files_to_extract ] [-d tempdir]
+.SH DESCRIPTION
+.B minizip
+is a simple tool which allows the extraction of compressed file
+archives in the ZIP format used by the MS-DOS utility PKZIP.  It was
+written as a demonstration of the
+.IR zlib (3)
+library and therefore lack many of the features of the
+.IR unzip (1)
+program.
+.SH OPTIONS
+A number of options are supported.  With the exception of
+.BI \-d\  tempdir
+these must be supplied before any
+other arguments and are:
+.TP
+.BI \-l\ ,\ \-\-v
+List the files in the archive without extracting them.
+.TP
+.B \-o
+Overwrite files without prompting for confirmation.
+.TP
+.B \-x
+Extract files (default).
+.PP
+The
+.I zipfile
+argument is the name of the archive to process. The next argument can be used
+to specify a single file to extract from the archive.
+
+Lastly, the following option can be specified at the end of the command-line:
+.TP
+.BI \-d\  tempdir
+Extract the archive in the directory
+.I tempdir
+rather than the current directory.
+.SH SEE ALSO
+.BR minizip (1),
+.BR zlib (3),
+.BR unzip (1).
+.SH AUTHOR
+This program was written by Gilles Vollant.  This manual page was
+written by Mark Brown <broonie@sirena.org.uk>. The -d tempdir option
+was added by Dirk Eddelbuettel <edd@debian.org>.

+.RI [ -o ]
+zipfile [ " files" ... ]
+.SH DESCRIPTION
+.B minizip
+is a simple tool which allows the creation of compressed file archives
+in the ZIP format used by the MS-DOS utility PKZIP.  It was written as
+a demonstration of the
+.IR zlib (3)
+library and therefore lack many of the features of the
+.IR zip (1)
+program.
+.SH OPTIONS
+The first argument supplied is the name of the ZIP archive to create or
+.RI -o
+in which case it is ignored and the second argument treated as the
+name of the ZIP file.  If the ZIP file already exists it will be
+overwritten.
+.PP
+Subsequent arguments specify a list of files to place in the ZIP
+archive.  If none are specified then an empty archive will be created.

Subject: Fixed bug in parent revision [832a1994c7] unpredictably breaking the
 execution of precompiled bytecode (i.e. tbcload'ed bytecode).

The semi-inversion of a guard condition dropped the part about
TCL_BYTECODE_PRECOMPILED of the original condition, allowing the core
to attempt to recompile code for which there are no script sources
(anymore), which then fails.

Subject: Confirmed that every caller of TclProcCompileProc() arranges for the
 procPtr and nsPtr arguments: nsPtr == procPtr->cmdPtr->nsPtr. This makes the
 test in TclCompileScript() useless. TCS() will always compile in the current
 namespace of the interp.  Remove the code that obfuscates that fact.

Date: Fri, 17 May 2013 07:14:13 +0000
Subject: Revert defining _HAVE_32BIT_TIME_T especially for mingw-4.0-rc1:
 Although it works, it has the side-effect that tcl8?.dll depends on
 msvcrt.dll symbols which are only available in later versions of msvcrt.dll.
 This is undesired, it really should be fixed in the mingw headers.

Subject: Stop emitting the instructions INST_*_SCALAR_STK*.  They are
 identical to their INST_*_STK* counterparts. Having done that, it is clear
 the "simpleVarName" return from TclPushVarName provides nothing of use to any
 of its callers.  Eliminate that.  Also make TPVN return void, instead of int.
 Bring the TPVN header comments up to date; they were quite rotten.

Subject: Improve compatibility detection for <time.h> and <sys/stat.h>: - Move
 <time.h> before other includes on Windows, so we are sure the time_t
 definition being checked doesn't come from <sys/types.h>. - Padding at the
 end of Tcl_StatBuf doesn't influcence binary compatibility, so relax panic
 check accordingly.

Subject: Select improvements in stack depth estimates brought over from
 mig-review.

Mostly these are just simplifications, removing code that wasn't needed.
Some changes make the stack depth estimate more accurate instruction by
instruction.

Subject: Revise INST_EXPAND_STKTOP so that it no longer makes use of its
 operand. All the information required to do a proper expansion of the exec
 stack to support expanded command invocation is already present.  The operand
 doesn't provide any essential information.  By ignoring it, we eliminate the
 risk that the compiler might fill in the operand with a bad stack depth
 estimate value.  INST_EXPAND_STKTOP doesn't need an operand, but in order to
 support loading of existing bytecodes we cannot change it now.  There's also
 no need to change what the compiler tries to place in the operand, though
 changing it to always be zeros would be acceptable now.

Subject: Modify internal TclStubInfoType type:  use TclStubs * in stead of
 ClientData, so less type casts are needed in the code. Disadvantage: somewhat
 more code duplication, but it makes the code much more understandable.

Subject: Don't use TclpInetNtoa any more, use inet_ntoa in stead. Since IP6
 support it's even not necessary any more (except for fake-rfc2553, but
 mutexes are used here already) , but it's in the internal stub table so we
 cannot remove it until 9.0

 the intent to generally simplify and make more readable, as well as find and
 eliminate duplication with ensemble machinery and improve mergeability to
 other branches.  Work in Progress.  Doesn't work at all right now.

Subject: Disabling the SetLineInformation() macro entirely causes only 3 tests
 in the test suite to fail.  Restoring just 2 SetLineInformation() calls fixes
 those failures.  The need for all the other SLI() calls is not demonstrated
 by any test.  Without more complete test coverage, it is difficult to
 confidently tweak the TIP 280 implementation without fear that changes are
 introducing breakage.

Subject: The value TCL_LOCATION_EVAL_LIST in the type field of a CmdFrame
 appears to exist only for the sake of taking great pains to make sure that
 pure list values remain pure list values.

The value of pure list values is no longer what it once was.  For a long long
time now, any canonical list values have been equally good.  This branch
is Work In Progress eliminating the complication of the additional type value.

Currently some minor botches are breaking execution tracing tests.

Subject: All use of the evalFlag value TCL_EVAL_CTX is unused by the code and
 unreachable by extensions.  This checkin removes all the code supporting that
 flag value.

The consequence is that all the calls to TclNREvalObjEx() and its callers
that are currently choosing not to pass the TCL_EVAL_DIRECT flag in when
they pass in a non-NULL invoker will no longer be free to change their
mind.  That might be reason not to adopt this change.

Subject: Use a new flag value TCL_EVAL_SOURCE_IN_FRAME passed in by callers to
 determine whether the pre-subst source information in a CmdFrame is to be
 used.  This takes the place of numLevels cross checking, so that field is
 removed.  Routines are consolidated as well.

Subject: Testing doing away with the NRRunObjProc routine, which looks like a
 useless extra bounce on the NRE trampoline.

Normal testing has no problem with it, but debug-enabled testing
triggers an assert failure.

Either it would be good to have a normal test that fails in the conditions
of the assert failure, or it would be good to discover the assert is
asserting something not actually required, and then make the purge.

 Tcl 8.6 that callers can pre-resolve a cmdPtr for us.  In that case a
 re-resolution in the form of another command name lookup isn't the right
 thing.

+A NOTE ON THE CHANGELOG:
+Starting in early 2011, Tcl source code has been under the management of
+fossil, hosted at http://core.tcl.tk/tcl/ .  Fossil presents a "Timeline"
+view of changes made that is superior in every way to a hand edited log file.
+Because of this, many Tcl developers are now out of the habit of maintaining
+this log file.  You may still find useful things in it, but the Timeline is
+a better first place to look now.

+.SH NAME
+Tcl_OOInitStubs \- initialize library access to TclOO functionality
+.SH SYNOPSIS
+.nf
+\fB#include <tclOO.h>\fR
+.sp
+const char *
+\fBTcl_OOInitStubs\fR(\fIinterp\fR)
+.fi
+.SH ARGUMENTS
+.AS Tcl_Interp *interp in
+.AP Tcl_Interp *interp in
+The Tcl interpreter that the TclOO API is integrated with and whose C
+interface is going to be used.
+.BE
+.SH DESCRIPTION
+.PP
+When an extension library is going to use the C interface exposed by TclOO, it
+should use \fBTcl_OOInitStubs\fR to initialize its access to that interface
+from within its \fI*\fB_Init\fR (or \fI*\fB_SafeInit\fR) function, passing in
+the \fIinterp\fR that was passed into that routine as context. If the result
+of calling \fBTcl_OOInitStubs\fR is NULL, the initialization failed and an
+error message will have been left in the interpreter's result. Otherwise, the
+initialization succeeded and the TclOO API may thereafter be used; the
+version of the TclOO API is returned.
+.PP
+When using this function, either the C #define symbol \fBUSE_TCLOO_STUBS\fR
+should be defined and your library code linked against the Tcl stub library,
+or that #define symbol should \fInot\fR be defined and your library code
+linked against the Tcl main library directly.
+.SH "BACKWARD COMPATIBILITY NOTE"
+.PP
+If you are linking against the Tcl 8.5 forward compatibility package for
+TclOO, \fIonly\fR the stub-enabled configuration is supported and you should
+also link against the TclOO independent stub library; that library is an
+integrated part of the main Tcl stub library in Tcl 8.6.
+.SH KEYWORDS

Subject: [98c8b3ec12] Use constraint to work around failing test; it's just a
 bug in the underlying library, and one that appears fixed in later versions.
 Not our fault if some OSes don't update. (It's also in a very esoteric spot.)

Subject: [01b77111e5]: Small fixes relating to this bug. In particular, the
 package name mapping was not being distributed, and there were some small
 problems with what the mappings were and how they were applied. Also
 prevented external URLs from ending with a '.'; that's vanishingly rare...

Subject: Bump tcltest version to 2.3.6 (should have been done just before the
 8.5.15 release, just as in Tcl 8.6.1). Don't fix eol-style for Makefile.in in
 "make dist", if the file system is case-insensitive/case-preserving.

Subject: Put extern "C" guards around all stub table struct definitions, so it
 is usable for C++ compilers as well without the danger of modifying the
 calling convention. For tclDecls.h it was no problem, because tcl.h already
 contains those guards. But for the other *Decls.h files (e.g.
 tclTomMathDecls.h) it was not correct.

Subject: Revert [5215b8740c] (Enh [2959069]), as it turns out that
 -fvisibility=hidden only affects definitions and not declarations. Therefore
 explicitely declaring each MODULE_SCOPE function as 
 __attribute__((__visibility__("hidden")) is much better. Suggested by Stuart
 Cassoff (Thanks!).

Subject: New compiler and bytecodes for foreach and lmap: 70% faster

   * speed as measured by http://wiki.tcl.tk/39021: runs in <1/3 the time

   * still need to adapt array-set to use this

   * assemble.test-16.5 or 16.6 bombs in a purify/symbols build (?)

   * removing the old opcodes would force recompilation of old .tbc files or adaptation of tbcload

Subject: Introducing a new union member in Tcl_Obj is not a good idea in a
 patch release, especially using "long". Better allow iterNum and iterMax to
 grow to ssize_t (or size_t) in Tcl 9 (or 8.x, why not?). Usage of "long" in
 public API causes interoperability problems between Cygwin64 and Win64
 (probably no-one cares except me).

 TEBC itself.

Subject: [2992970] Restore the safety of Tcl_AppendObjToObj(x, x) for
 bytearrays. Also moves overflow checking to TclAppendBytesToByteArray() and
 adds the ability to call TABTBA() with bytes==NULL, for appending unspecified
 bytes.  That is, the string grows, but the new bytes are of undetermined
 value.  Like Tcl_NewByteArrayObj(NULL, length) this option is useful for
 manipulating buffers.  The TABTBA growth algorithm is also enhanced a bit,
 copying over a fuller implementation from GrowStringBuffer() in
 tclStringObj.c

From 8703cd164100a81207d646099206dcc3acdf05bb Mon Sep 17 00:00:00 2001

Subject: Revise the Tcl_Append* machinery to tolerate NULL bytes to append.
 Then have ReadChars() use that machinery to resize buffer receiving input,
 rather than invent its own version.  Simplify ReadChars() callers.

Subject: Revised ReadChars to restore an attempt to make sure we do not short
 read because of a false notion of limited storage space. The test suite does
 not appear to demonstrate any case where this matters. Could be an incomplete
 test suite, or an example of pointless code.

Subject: [a4494e28ed] Use flag bit instead of NULL pointer to suppress
 teardown list of imported commands when the original command gets re-created.
  This prevents the panic otherwise possible when the invalid state
 represented by the NULL pointer is encountered during a command delete trace.

Subject: Simplify macro handling in tclOO*Decls.h, just as already done in
 "novem" [0c37ab8944], itcl*Decls.h and tdbc*Decls.h. This doesn't change the
 way symbols are exported. This simplifications were already present in the
 Tcl 8.6.2 headers, but those were buggy when tclOO was linked in statically
 without using stubs.

Subject: More ReadChars rewriting.  Test suite now passes. Note that this
 reform simplifies ReadChars a fair bit (at least in my eyes). Also it does
 away with the use of an INPUT_NEED_NL flag, using the same strategy for
 partial \r\n sequences as is used for incomplete multibyte chars.

-     * [Bug 1462248]: The cause of the crash reported in this bug is this:
-     *
-     * - ReadChars, called with a single buffer, with a incomplete
-     *	 multi-byte character at the end (only the first byte of it).
-     * - Encoding translation fails, asks for more data
-     * - Data is read, and eof is reached, TCL_ENCODING_END (TEE) is set.
-     * - ReadChar is called again, converts the first buffer, but due to TEE
-     *	 it does not check for incomplete multi-byte data, and the character
-     *	 just after the end of the first buffer is a valid completion of the
-     *	 multi-byte header in the actual buffer. The conversion reads more
-     *	 characters from the buffer then present. This causes nextRemoved to
-     *	 overshoot nextAdded and the next reads compute a negative srcLen,
-     *	 cause further translations to fail, causing copying of data into the
-     *	 next buffer using bad arguments, causing the mecpy for to eventually
-     *	 fail.
-     *
-     * In the end it is a memory access bug spiraling out of control if the
-     * conditions are _just so_. And ultimate cause is that TEE is given to a
-     * conversion where it should not. TEE signals that this is the last
-     * buffer. Except in our case it is not.
-     *
-     * My solution is to suppress TEE if the first buffer is not the last. We
-     * will eventually need it given that EOF has been reached, but not right
-     * now. This is what the new flag "endEncSuppressFlag" is for.
-     *
-     * The bug in 'Tcl_Utf2UtfProc' where it read from memory behind the
-     * actual buffer has been fixed as well, and fixes the problem with the
-     * crash too, but this would still allow the generic layer to
-     * accidentially break a multi-byte sequence if the conditions are just

 fail.

Subject:   *  More test improvements for async sockets.   *  Advance async
 connections whenever the channel is touched (e.g. by [chan configure]).   * 
 Add a noblock argument to WaitForConnect(), so that advancing async
 connections from [chan configure] doesn't block even on a blocking socket.

- *	This function opens a new socket in client mode.

  *
- *	This might be called in 3 circumstances:

- *	-   By the event handler to continue an asynchroneous connect
- *	-   By a blocking socket function (gets/puts) to terminate the
- *	    connect synchroneously
+ *	Note: This code is based on code contributed by John Haxby.
  *
  * Results:
- *      TCL_OK, if the socket was successfully connected or an asynchronous
- *      connection is in progress. If an error occurs, TCL_ERROR is returned
- *      and an error message is left in interp.

- * Remarks:

- *	connection attempt is in progress, it sets up itself as a writable
- *	event handler for that socket, and returns. When the callback occurs,
- *	control is transferred to the "reenter" label, right after the initial
- *	return and the loops resume as if they had never been interrupted.
- *	For syncronously connecting sockets, the loops work the usual way.

Subject: Revert the tests for bug#97069ea11a from socket.test, because it is
 hard to test with the socket command in a platform-independent way. As the
 bug is in tclIOChan.c and should be tested there with a dummy channel driver
 that can reliably reproduce the situation that suppresses the error message.

Subject:   *  Rework WaitForConnect() to fix synchronous completion of
 asynchronous connections.   *  Let TcpInputProc() and TcpOutputProc() fail
 before calling any I/O syscalls when an asynchronous connection has failed.  
 *  Adjust the tests accordingly.

Subject: Changed error report logic, that an async connect error is only
 reported by 'fconfigure -error' and not by a possible last command
 terminating the async connect. The terminating command always returns "socket
 is not connected" on connect error. In addition, some flags were renamed:
 TCP_ASYNC_SOCKET to TCP_NONBLOCKING and also the new state flags.

Subject:   *  Give clearer names to some of the state flags and sync them with
 Windows where it makes sense.   *  Rework WaitForConnect once more to always
 report ENOTCONN on I/O operations on failed async sockets.   *  Fix
 synchronous connections to a server that only listens on IPv6 (or whatever
 comes later in the list returned by getaddrinfo(), socket-15.*)   *  Fix
 spurious writable event on async sockets (socket-14.15).

Subject: Fix [3118489] for Windows only: NUL in filenames. This allows various
 characters to be used in win32 filenames which are normally invalid, as
 described here:
 [http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-specialchars].
 The Cygwin shell can handle those same filenames as well. In other shells
 (cmd.exe/mSys) or on the Windows desktop the filenames will look strange, but
 that's all.

Subject: Fix [3118489]: NUL in filenames, now fixed for both Windows and UNIX.
 For consistancy, any NUL character in a filename prevents the native
 filesystem to generate a native file representation for it. Other filesystems
 than the native one may still accept it, but it's not recommended.

Subject: Upgrade from Winsock 1.1 to Winsock 2.2, which is always available on
 Win2000+. See:
 [http://msdn.microsoft.com/en-us/library/windows/desktop/ms742213%28v=vs.85%29.aspx]
 for details. Move winsock initialization to TclpInitPlatform(void), so we can
 be sure everywhere that we have an initialized winsock2. Stub entries for
 TclWinGetServByName/TclWinGetSockOpt/TclWinSetSockOpt are no longer necessary
 (will be removed in 9.0, but are kept in 8.x)

Subject: Simplify reflected channels. Instead of having two modes of Close
 operations and the need to choose between them with a special value of the
 methods field, when the initialize pass fails for some reason, simply do not
 create the channel so there's nothing that needs closing.  Then the methods
 field no longer holds anything used, so eliminate it.  All the methods
 checking is done by [chan create].

Subject: Memory leak after thread exit, fixed (alloc cache released by exit),
 belong to ticket [3493120]

Moved over to branch bug-3493120.  This is not ready
for the core-8-5-branch.  Segfaults all over the place
in a thread-enabled build on a CentOS system.

Subject: Stop the segfault in iogt-2.4.  First by changing the
 UpdateInterest() call that triggers it.  "downChanPtr" may no longer be the
 right argument at that point.  Second, after ending the segfault, the test
 became an infinite loop (nested unstacking?!  whoa.), so revised the test to
 one that terminates (and passes).  Left behind a comment that the recursive
 unstacking case may require more examination.

Subject: More efficient/robust implementation of function
 TclNativeCreateNativeRep(). - No more intermediate results in a Tcl_DString,
 just allocate space directly. - Let MultiByteToWideChar() do all the
 difficult work, inclusive checking for invalid byte sequences. - Handled
 extended win32 paths, inclusive UNC paths. Implementation for a great deal
 taken over from fossil.

Subject: Fix the panic in iogt-2.5. Back in 2011, Bugs 3384654 and 3393276
 first noticed troubles with ChannelBuffer sharing, but the magnitude of the
 problem wasn't truly grasped.  A fix was applied that turned out to be more
 of a band-aid workaround.  Now that the real fix is in place, the band-aid is
 actually preventing it working properly in thie case.  Rip it off!

Subject: Tests (chan)io-34.21 are constrained for largefileSupport, and that's
 disabled by default, which means never tested, which means the ridiculous
 bugs in them are never found and fixed.

Fixed the bugs, changed the default.  Large File Suppport (4GB) is
commonplace now.  Let those without it suffer a few failing tests reporting
that fact to them.

Subject: Workarounds and fixes for wrapped executables on various platforms
 regarding the handling of wrapped dynamic libraries.

The basic flow of operation is to copy such libraries into a temp
file, hand them to the OS loader for processing, and then to delete
them immediately, to prevent them from being accessible to other
executables. On platforms where that is not possible the library is
left in place and things are arranged to delete it on regular process
exit.

An example of the latter are older revisions of HPUX which report that
the file is busy when trying to delete it. Younger revisions of HPUX
have changed to allow the deletion, but are also buggy, the OS loader
mangles its data structures so that a second library loaded in this
manner fails.

More recently it was found that Linux which is usually ok with
deleting the file and gets everything right shows the same trouble as
modern HPUX when the "docker" containerization system is involved, or
more specifically the AUFS in use there. Deleting the loaded library
file mangles data structures and breaks loading of the following
libraries. For a demonstration which does not involve Tcl at all see
the ticket

     https://github.com/dotcloud/docker/issues/1911

in the docker tracker.

This of course breaks the use of wrapped executables within docker
containers.

This commit introduces the function TclSkipUnlink() which centralizes
the handling of such exceptions to unlinking the library after unload,
and provides code handling the known cases. IOW HPUX is generally
forced to not unlink, and ditto when we detect that the copied library
file resides within an AUFS.

The latter must however be explicitly activated by setting the define
-DTCL_TEMPLOAD_NO_UNLINK during build. We still need proper configure
tests to set it on the relevant platforms (i.e. Linux).

The AUFS detection and handling can be overridden by the environment
variable TCL_TEMPLOAD_NO_UNLINK which can force the behaviour either
way (skip or not). In case the user knows best, or wishes to test if
the problem with AUFS has been fixed.

Subject: Correct the interest masks in the Tcl_CreateFileHandler() calls in
 PipeWatchProc().  When we are interested in both readable and writable events
 of a command pipeline channel, we only want the readable from the read end of
 the pipe, and the writable from the write end of the pipe.

Subject: These edits make all tests outside of socket-14.* pass on OSX
 Mavericks. Several socket-14.* tests failing there, and those that pass are
 very slow about it.  Firewall or poor networking configuration may be playing
 a role.

Subject: Revise DiscardOutput() to account for revisions to the loop in
 FlushChannel() which is its only caller.  We need to discard the curOutPtr
 buffer as well, and not count on another pass through the loop to attempt to
 flush it (and raise the same failure again?).

From: andreask <andreask>

Subject: Fixed a tricky interaction of IO system and encodings which could
 result in a panic.

The relevant function is ReadChars() (short RC in the following).

When the encoding and translation transforms deliver more characters
than were requested the iterative algorithm used by RC reduces the
value of "dstLimit" (= the number of bytes allowed to be copied into
the destination buffer) to force the next round to deliver less
characters, hopefully the number requested.

The existing code used the byte located just after the last wanted
character to determine the new limit. The resulting value could
_undershoot_ the best possible limit because Tcl_ExternalToUtf would
effectively reduce this limit further, by TCL_UTF_MAX+1, to have
enough space for a single multi-byte character in the buffer, and a
closing '\0' as well.

One effect of this were additional calls to ReadChars() to retrieve
the characters missed by a call with an undershot limit.

In the limit (sic) however this was also able to cause a full-blown
"Buffer Underflow" panic if the original request was for less than
TCL_UTF_MAX characters (*), and we are using a single-byte encoding
like iso-8859-1. Because then the undershot dstLimit would prevent the
next round from copying anything, and causing it to try and
consolidate the current buffer with the next buffer, thinking that it
had to merge a multi-byte character split across buffer boundaries.

(Ad *) For example because the previous call had undershot already and
left only such a small amount of characters behind!

The basic fix to the problem is to add TCL_UTF_MAX back to the limit,
like is done in all the (three) other places in RC setting a new
one. Note however that this naive fix may generate a new limit which
is the same as the old, or possibly larger. If that happens we act
very conservatively and reduce the limit by only one byte instead.

While I believe that this last conservative approach will never reduce
the limit to TCL_UTF_MAX or less before reaching a state where it
returnds the exact amount of requested characters I still added a
check against this situation anyway, causing a new panic if triggered.

Subject: When too many chars are read by ReadChars() and we trim the limits to
 get it right on the next pass, don't forget the TCL_UTF_MAX padding demanded
 by Tcl_ExternalToUtf().  (Thanks for finding that, aku!) Fix the factorPtr
 management.  It was just totaly wrong. The factor should be a ratio of the
 record of bytes read to the record of chars read. With those fixes, new test
 io-12.6 covers the "too many chars" code.

Subject: Workaround the broken select() in some Linux kernels that fails to
 report a writable state on a socket when an error condition (or remote close)
 is present.  Would be good to add actual test suite tests for this, but until
 then see demo scripts in the ticket 1758a0b603.

Subject: The write and flush operations of reflected transforms ([chan push])
 have been converting all lower level channel errors from Tcl_WriteRaw() into
 EINVAL.  Generally this is a perplexing discard of useful information, but
 worse it interferes with the EAGAIN signalling that is required to manage the
 BLOCKED state of a nonblocking channel.  Thanks to aspect for demo scripts
 that pointed to the bug.

Subject: Starting with Unicode 6.3, the mongolian vowel separator (U+180e) is
 no longer a whitespace, but for Tcl it still is. "NEL/Next Line" (U+0085)
 should have been a Unicode whitespace, but never was in Tcl. This is
 corrected in Tcl 8.6, but for legacy reasons not in Tcl 8.5. Update
 documentation accordingly, and extend test-cases for Unicode 7 compliance.
