	error in function naming which blocked a threaded test build.

2009-11-19  Jan Nijtmans  <nijtmans@users.sf.net>

	* win/Makefile.in:	Create tcltest86.dll as dynamic Tcltest
				package.
	* generic/tclTest.c:	Remove extraneous prototypes, follow-up to
	* generic/tclTestObj.c:	[Bug 2883850]
	* tests/chanio.test:	Test-cases for fixed [Bug 2849797]
	* tests/io.test:
	* tests/safe.test:	Fix safe-10.1 and safe-10.4 test cases, making
				the wrong assumption that Tcltest is a static
				package.
	* generic/tclEncoding.c:[Bug 2857044]: Updated freeIntRepProc routines
	* generic/tclVar.c:	so that they set the typePtr field to NULL so
				that the Tcl_Obj is not left in an
				inconsistent state.
	* unix/tcl.m4:		[Patch 2883533]: tcl.m4 support for Haiku OS
	* unix/configure:	autoconf-2.59

2009-11-19  Don Porter  <dgp@users.sourceforge.net>

	(SetupTimeZone, ProcessPosixTimeZone):	Restored the use of a literal
	* library/history.tcl (HistAdd):	'then' when following a multi-
	* library/safe.tcl (interpConfigure):	line test expresssion. It's an
	* library/tm.tcl (UnknownHandler):	aid to readability then.

2009-11-19  Jan Nijtmans  <nijtmans@users.sf.net>

	* generic/tclInt.h       Make all internal initialization

	* generic/tclTestObj.c
	* generic/tclTestProcBodyObj.c
	* generic/tclThreadTest.c
	* unix/Makefile.in       Fix [Bug 2883850]: pkgIndex.tcl doesn't

	* unix/tclXtTest.c
	* unix/tclXtNotify.c
	* unix/tclUnixTest.c
	* win/Makefile.in
	* win/tcl.m4

	* win/tclAppInit.c
	* win/tclWinDde.c        Always compile with Stubs.
	* win/tclWinReg.c
	* win/tclWinTest.c

2009-11-18  Jan Nijtmans  <nijtmans@users.sf.net>

	* doc/CrtChannel.3:	[Bug 2849797]: Fix channel name inconsistences
	* generic/tclIORChan.c:	as suggested by DKF.
	* generic/tclIO.c:	Minor *** POTENTIAL INCOMPATIBILITY ***

	* generic/tclBasic.c
	* generic/tclBinary.c
	* generic/tclCmdAH.c

	* tools/tsdPerf.c

2009-11-17  Andreas Kupries  <andreask@activestate.com>

	* unix/tclUnixChan.c (TtyParseMode): Partial undo of Donal's tidy-up
	from a few days ago (2009-11-9, not in ChangeLog). It seems that
	strchr is apparently a macro on AIX and reacts badly to pre-processor
	directives in its arguments.

2009-11-16  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>

	* generic/tclEncoding.c:  [Bug 2891556]: Fix and improve test to
	* generic/tclTest.c:	  detect similar manifestations in the future.
	* tests/encoding.test:    Add tcltest support for finalization.

2009-11-15  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/tclWinDde.c: Avoid gcc compiler warning by explicitly casting
	DdeCreateStringHandle argument.

2009-11-12  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c (CopyData): [Bug 2895565]: Dropped bogosity which
	* tests/io.test: used the number of _written_ bytes or character to
	update the counters for the read bytes/characters. New test io-53.11.
	This is a forward port from the 8.5 branch.

2009-11-11  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclClock.c (TclClockInit):    Do not create [clock] support
	commands in safe interps.

2009-11-11  Jan Nijtmans  <nijtmans@users.sf.net>

	* library/http/http.tcl (http::geturl): [Bug 2891171]: URL checking
	too strict when using multiple question marks.
	* tests/http.test
	* library/http/pkgIndex.tcl:  Bump to http 2.8.2
	* unix/Makefile.in:
	* win/Makefile.in:

2009-11-11  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>

	* generic/tclIO.c: Fix [Bug 2888099] (close discards ENOSPC error)
	                   by saving the errno from the first of two
	                   FlushChannel()s. Uneasy to test; might need
	                   specific channel drivers. Four-hands with aku.

2009-11-10  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* tests/winFCmd.test: Cleanup directories that have been set chmod
	000. On Windows7 and Vista we really have no access and these were
	getting left behind.
	A few tests were changed to reflect the intent of the test where
	setting a directory chmod 000 should prevent any modification. This
	restriction was ignored on XP but is honoured on Vista

2009-11-10  Andreas Kupries  <andreask@activestate.com>

	* generic/tclBasic.c: Plug another leak in TCL_EVAL_DIRECT evaluation.
	Forward port from Tcl 8.5 branch, change by Don Porter.

	* generic/tclObj.c: [Bug 2895323]: Plug memory leak in
	TclContinuationsEnter(). Forward port from Tcl 8.5 branch, change by
	Don Porter.

2009-11-09  Stuart Cassoff <stwo@users.sf.net>

	* win/README: [bug 2459744]: Removed outdated Msys + Mingw info.

2009-11-09  Andreas Kupries  <andreask@activestate.com>

	* generic/tclBasic.c (TclEvalObjEx): Moved the #280 decrement of
	refCount for the file path out of the branch after the whole
	conditional, closing a memory leak. Added clause on structure type to
	prevent seg.faulting. Forward port from valgrinding the Tcl 8.5
	branch.

	* tests/info.test: Resolve ambiguous resolution of variable "res".
	Forward port from 8.5

2009-11-08  Donal K. Fellows  <dkf@users.sf.net>

	* doc/string.n (bytelength): Noted that this command is not a good
	thing to use, and suggested a better alternatve. Also factored out the
	description of the indices into its own section.

2009-11-07  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* tests/fCmd.test: [Bug 2891026]: Exclude tests using chmod 555
	directories on vista and win7. The current user has access denied and
	so cannot rename the directory without admin privileges.

2009-11-06  Andreas Kupries  <andreask@activestate.com>

	* library/safe.tcl (::safe::Setup): Added documentation of the
	contents of the state array. Also killed the 'InterpState' procedure
	with its upleveled variable/upvar combination, and replaced all uses
	with 'namespace upvar'.

2009-11-05  Andreas Kupries  <andreask@activestate.com>

	* library/safe.tcl: A series of patches which bring the SafeBase up to
	date with code guidelines, Tcl's features, also eliminating a number
	of inefficiencies along the way.
	(1) Changed all procedure names to be fully qualified.
	(2) Moved the procedures out of the namespace eval. Kept their
	locations. IOW, broke the namespace eval apart into small sections not
	covering the procedure definitions.
	(3) Reindented the code. Just lots of whitespace changes.
	Functionality unchanged.
	(4) Moved the multiple namespace eval's around. Command export at the
	top, everything else (var decls, argument parsing setup) at the
	bottom.
	(5) Moved the argument parsing setup into a procedure called when the
	code is loaded. Easier management of temporary data.
	(6) Replaced several uses of 'Set' with calls to the new procedure
	'InterpState' and direct access to the per-slave state array.
	(7) Replaced the remaining uses of 'Set' and others outside of the
	path/token handling, and deleted a number of procedures related to
	state array access which are not used any longer.
	(8) Converted the path token system to cache normalized paths and path
	<-> token conversions. Removed more procedures not used any longer.
	Removed the test cases 4.3 and 4.4 from safe.test. They were testing
	the now deleted command "InterpStateName".
	(9) Changed the log command setup so that logging is compiled out
	completely when disabled (default).
	(10) Misc. cleanup. Inlined IsInterp into CheckInterp, its only user.
	Consistent 'return -code error' for error reporting. Updated to use
	modern features (lassign, in/ni, dicts). The latter are used to keep a
	reverse path -> token map and quicker check of existence.
	(11) Fixed [Bug 2854929]: Recurse into all subdirs under all TM root
	dirs and put them on the access path.

2009-11-02  Kevin B. Kenny  <kennykb@acm.org>

	* library/tzdata/Asia/Novokuznetsk: New tzdata locale for Kemerovo
	oblast', which now keeps Novosibirsk time and not Kranoyarsk time.
	* library/tzdata/Asia/Damascus: Syrian DST changes.
	* library/tzdata/Asia/Hong_Kong: Hong Kong historic DST corrections.
	Olson tzdata2009q.
	
2009-11-02  Donal K. Fellows  <dkf@users.sf.net>

	* doc/object.n (DESCRIPTION): Substantive revision to make it clearer
	what the fundamental semantics of an object actually are.

2009-11-01  Joe Mistachkin  <joe@mistachkin.com>

	* doc/Cancel.3: Minor cosmetic fixes.
	* win/makefile.vc: Make htmlhelp target work again.  An extra set of
	double quotes around the definition of the HTML help compiler tool
	appears to be required.  Previously, there was one set of double
	quotes around the definition of the tool and one around the actual
	invocation.  This led to confusion because it was the only such tool
	path to include double quotes around its invocation.  Also, it was
	somewhat inflexible in the event that somebody needed to override the
	tool command to include arguments.  Therefore, even though it may look
	"wrong", there are now two double quotes on either side of the tool
	path definition.  This fixes the problem that currently prevents the
	htmlhelp target from building and maintains flexibility in case
	somebody needs to override it via the command line or an environment
	variable.

2009-11-01  Joe English  <jenglish@users.sourceforge.net>

	* doc/Eval.3, doc/Cancel.3: Move TIP#285 routines out of Eval.3 into
	their own manpage.

2009-10-31  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclBasic.c (ExprRoundFunc): [Bug 2889593]: Correctly report
	the expected number of arguments when generating an error for round().

2009-10-30  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* tests/tcltest.test: When creating the notwritabledir we deny the
	current user access to delete the file. We must grant this right when
	we cleanup. Required on Windows 7 when the user does not automatically
	have administrator rights.

2009-10-29  Don Porter  <dgp@users.sourceforge.net>

	* generic/tcl.h:        Changed the typedef for the mp_digit type
	from:
		typedef unsigned long mp_digit;
	to:
		typedef unsigned int mp_digit;
	For 32-bit builds where "long" and "int" are two names for the same
	thing, this is no change at all.  For 64-bit builds, though, this
	causes the dp[] array of an mp_int to be made up of 32-bit elements
	instead of 64-bit elements.  This is a huge improvement because details
	elsewhere in the mp_int implementation cause only 28 bits of each
	element to be actually used storing number data.  Without this change
	bignums are over 50% wasted space on 64-bit systems.  [Bug 2800740].

	***POTENTIAL INCOMPATIBILITY***
	For 64-bit builds, callers of routines with (mp_digit) or (mp_digit *)
	arguments *will*, and callers of routines with (mp_int *) arguments
	*may* suffer both binary and stubs incompatibilities with Tcl releases
	8.5.0 - 8.5.7.  Such possibilities should be checked, and if such
	incompatibilities are present, suitable [package require] requirements
	on the Tcl release should be put in place to keep such built code
	[load]-ing only in Tcl interps that are compatible.

2009-10-29  Donal K. Fellows  <dkf@users.sf.net>

	* tests/dict.test: Make variable-clean and simplify tests by utilizing
	the fact that dictionaries have defined orders.

	* generic/tclZlib.c (TclZlibCmd): Remove accidental C99-ism which
	reportedly makes the AIX native compiler choke.

2009-10-29  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl (LocalizeFormat):
	* tests/clock.test (clock-67.1):
	[Bug 2819334]: Corrected a problem where '%%' followed by a letter in
	a format group could expand recursively: %%R would turn into %%H:%M:%S
	
2009-10-28  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclLiteral.c:	[Bug 2888044]: Fixed 2 bugs.
	* tests/info.test:	First, as noted in the comments of the
	TclCleanupLiteralTable routine, since the teardown of the intrep of
	one Tcl_Obj can cause the teardown of others in the same table, the
	full table cleanup must be done with care, but the code did not
	contain the same care demanded in the comment.  Second, recent
	additions to the info.test file had poor hygiene, leaving an array
	variable ::a lying around, which breaks later interp.test tests during
	a -singleproc 1 run of the test suite.

2009-10-28  Kevin B. Kenny  <kennykb@acm.org>

	* tests/fileName.test (fileName-20.[78]): Corrected poor test
	hygiene (failure to save and restore the working directory) that
	caused these two tests to fail on Windows (and [Bug 2806250] to be
	reopened).

2009-10-27  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclPathObj.c: [Bug 2884203]: Missing refcount on cached
	normalized path caused crashes.

2009-10-27  Kevin B. Kenny  <kennykb@acm.org>
	
	* library/clock.tcl (ParseClockScanFormat): [Bug 2886852]: Corrected a
	problem where [clock scan] didn't load the timezone soon enough when
	processing a time format that lacked a complete date.
	* tests/clock.test (clock-66.1):
	Added a test case for the above bug.
	* library/tzdata/America/Argentina/Buenos_Aires:
	* library/tzdata/America/Argentina/Cordoba:
	* library/tzdata/America/Argentina/San_Luis:
	* library/tzdata/America/Argentina/Tucuman: 
	New DST rules for Argentina. (Olson's tzdata2009p.)

2009-10-26  Don Porter  <dgp@users.sourceforge.net>

	* unix/Makefile.in:	Remove $(PACKAGE).* and prototype from the
	`make distclean` target.  Completes 2009-10-20 commit.

2009-10-24  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl (ProcessPosixTimeZone): 
	Corrected a regression in the fix to [Bug 2207436] that caused
	[clock] to apply EU daylight saving time rules in the US.
	Thanks to Karl Lehenbauer for reporting this regression.
	* tests/clock.test (clock-52.4):
	Added a regression test for the above bug.
	* library/tzdata/Asia/Dhaka:
	* library/tzdata/Asia/Karachi:
	New DST rules for Bangladesh and Pakistan. (Olson's tzdata2009o.)
	
2009-10-23  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c (FlushChannel): Skip OutputProc for low-level
	0-length writes. When closing pipes which have already been closed
	not skipping leads to spurious SIG_PIPE signals. Reported by
	Mikhail Teterin <mi+thun@aldan.algebra.com>.

2009-10-22  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOOBasic.c (TclOO_Object_VarName): [Bug 2883857]: Allow
	the passing of array element names through this method.

2009-10-21  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclPosixStr.c: [Bug 2882561]: Work around oddity on Haiku OS
	where SIGSEGV and SIGBUS are the same value.

	* generic/tclTrace.c (StringTraceProc): [Bug 2881259]: Added back cast
	to work around silly bug in MSVC's handling of auto-casting.

2009-10-20  Don Porter  <dgp@users.sourceforge.net>

	* unix/Makefile.in:	Removed the long outdated and broken targets
	package-* that were for building Solaris packages.  Appears that the
	pieces needed for these targets to function have never been present in
	the current era of Tcl development and belong completely to Tcl
	pre-history.

2009-10-19  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclIO.c:      [Patch 2107634]: Revised ReadChars and
	FilterInputBytes routines to permit reads to continue up to the string
	limits of Tcl values.  Before revisions, large read attempts could
	panic when as little as half the limiting value length was reached.
	Thanks to Sean Morrison and Bob Parker for their roles in the fix.

2009-10-18  Joe Mistachkin  <joe@mistachkin.com>

	* generic/tclObj.c (TclDbDumpActiveObjects, TclDbInitNewObj)
	(Tcl_DbIncrRefCount, Tcl_DbDecrRefCount, Tcl_DbIsShared):
	[Bug 2871908]: Enforce separation of concerns between the lineCLPtr
	and objThreadMap thread specific data members.

2009-10-18  Joe Mistachkin  <joe@mistachkin.com>

	* tests/thread.test (thread-4.[345]): [Bug 1565466]: Correct tests to
	save their error state before the final call to threadReap just in case
	it triggers an "invalid thread id" error.  This error can occur if one
	or more of the target threads has exited prior to the attempt to send
	it an asynchronous exit command.

2009-10-17  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclVar.c (UnsetVarStruct, TclDeleteNamespaceVars)
	(TclDeleteCompiledLocalVars, DeleteArray): 
	* generic/tclTrace.c (Tcl_UntraceVar2): [Bug 2629338]: Stop traces
	that are deleted part way through (a feature used by tdom) from
	causing freed memory to be accessed.

2009-10-08  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclDictObj.c (DictIncrCmd): [Bug 2874678]: Don't leak any
	bignums when doing [dict incr] with a value.
	* tests/dict.test (dict-19.3): Memory leak detection code.

2009-10-07  Andreas Kupries  <andreask@activestate.com>

	* generic/tclObj.c: [Bug 2871908]: Plug memory leaks of objThreadMap
	and lineCLPtr hashtables.  Also make the names of the continuation
	line information initialization and finalization functions more
	consistent. Patch supplied by Joe Mistachkin <joe@mistachkin.com>.

	* generic/tclIORChan.c (ErrnoReturn): Replace hardwired constant 11
	with proper errno #define, EAGAIN. What was I thinking? The BSD's have
	a different errno assignment and break with the hardwired number.
	Reported by emiliano on the chat.

2009-10-06  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInterp.c (SlaveEval): Agressive stomping of internal reps
	was added as part of the NRE patch of 2008-07-13.  This doesn't appear
	to actually be needed, and it hurts quite a bit when large lists lose
	their intreps and require reparsing.  Thanks to Ashok Nadkarni for
	reporting the problem.

	* generic/tclTomMathInt.h (new): Public header tclTomMath.h had
	* generic/tclTomMath.h:	dependence on private headers, breaking use
	* generic/tommath.h:	by extensions [Bug 1941434].

2009-10-05  Andreas Kupries  <andreask@activestate.com>

	* library/safe.tcl (AliasGlob): Fixed conversion of catch to
	  try/finally, it had an 'on ok msg' branch missing, causing a
	  silent error immediately, and bogus glob results, breaking
	  search for Tcl modules.

2009-10-04  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/tclMacOSXBundle.c:	Workaround CF memory managment bug in
	* unix/tclUnixInit.c:		Mac OS X 10.4 & earlier. [Bug 2569449]

2009-10-02  Kevin B. Kenny  <kennykb@acm.org>

	* library/tzdata/Africa/Cairo:
	* library/tzdata/Asia/Gaza:
	* library/tzdata/Asia/Karachi:
	* library/tzdata/Pacific/Apia:	Olson's tzdata2009n.

2009-09-29  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclDictObj.c:		[Bug 2857044]: Updated freeIntRepProc
	* generic/tclExecute.c:		routines so that they set the typePtr
	* generic/tclIO.c:		field to NULL so that the Tcl_Obj is
	* generic/tclIndexObj.c:	not left in an inconsistent state.
	* generic/tclInt.h:
	* generic/tclListObj.c:
	* generic/tclNamesp.c:
	* generic/tclOOCall.c:
	* generic/tclObj.c:
	* generic/tclPathObj.c:
	* generic/tclProc.c:
	* generic/tclRegexp.c:
	* generic/tclStringObj.c:

	* generic/tclAlloc.c:           Cleaned up various routines in the
	* generic/tclCkalloc.c:         call stacks for memory allocation to
	* generic/tclInt.h:             guarantee that any size values computed
	* generic/tclThreadAlloc.c:     are within the domains of the routines
	they get passed to.  [Bugs 2557696 and 2557796].

2009-09-28  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c:	Replaced TclProcessReturn() calls with
	* tests/error.test:	Tcl_SetReturnOptions() calls as a simple fix
	for [Bug 2855247].  Thanks to Anton Kovalenko for the report and fix.
	Additional fixes for other failures demonstrated by new tests.

2009-09-27  Don Porter  <dgp@users.sourceforge.net>

	* tests/error.test (error-15.8.*):	Coverage tests illustrating
	flaws in the propagation of return options by [try].

2009-09-26  Donal K. Fellows  <dkf@users.sf.net>

	* unix/tclooConfig.sh, win/tclooConfig.sh: [Bug 2026844]: Added dummy
	versions of tclooConfig.sh that make it easier to build extensions
	against both Tcl8.5+TclOO-standalone and Tcl8.6.

2009-09-24  Don Porter  <dgp@users.sourceforge.net>

	TIP #356 IMPLEMENTATION

	* generic/tcl.decls:	Promote internal routine TclNRSubstObj()
	* generic/tclCmdMZ.c:	to public Tcl_NRSubstObj().  Still needs docs.

2009-09-21  Mo DeJong  <mdejong@users.sourceforge.net>

	* tests/regexp.test: Added check for error message from

2009-09-21  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompile.c:	Correct botch in the conversion of
	Tcl_SubstObj().  Thanks to Kevin Kenny for detection and report.

2009-09-17  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompile.c:	Re-implement Tcl_SubstObj() as a simple
	* generic/tclParse.c:	wrapper around TclNRSubstObj().  This has
	* tests/basic.test:	the effect of caching compiled bytecode in
	* tests/parse.test:	the value to be substituted.  Note that
	Tcl_SubstObj() now exists only for extensions.  Tcl itself no longer
	makes any use of it.  Note also that TclSubstTokens() is now reachable
	only by Tcl_EvalEx() and Tcl_ParseVar() so tests aiming to test its
	functioning needed adjustment to still have the intended effect.

2009-09-16  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>

	* generic/tclCompCmds.c (TclCompileSubstCmd): [Bug 2314561]:
	* generic/tclBasic.c:	Added a bytecode compiler routine for the
	* generic/tclCmdMZ.c:	[subst] command. This is a partial solution to
	* generic/tclCompile.c:	the need to NR-enable [subst] since bytecode
	* generic/tclCompile.h:	execution is already NR-enabled. Two new
	* generic/tclExecute.c:	bytecode instructions, INST_NOP and
	* generic/tclInt.h:	INST_RETURN_CODE_BRANCH were added to support
	* generic/tclParse.c:	the new routine.  INST_RETURN_CODE_BRANCH is
	* tests/basic.test:	likely to be useful in any future effort to
	* tests/info.test:	add a bytecode compiler routine for [try].
	* tests/parse.test:

2009-09-01  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIORTrans.c (ReflectInput): Remove error response to
	0-result from method 'limit?' of transformations. Return the number of
	copied bytes instead, which is possibly nothing. The latter then
	triggers EOF handling in the higher layers, making the 0-result of
	limit? the way to inject artificial EOF's into the data stream.

	* generic/tclPathObj.c: [Bug 2806250]: Prevent the storage of strings
	starting with ~ in the "tail" part (normPathPtr field) of the path
	intrep when PATHFLAGS != 0.  This establishes the assumptions relied
	on elsewhere that the name stored there is a relative path.  Also

	* generic/tclCmdAH.c (TclNRForObjCmd, TclNRForIterCallback,
	(ForNextCallback):
	* generic/tclCmdMZ.c (TclNRWhileObjCmd):

	Extended the bytecode compiler initialization to recognize the
	compilation of whole files (NRE enabled 'source' command) and switch
	to the counting of absolute lines in that case.

	Further extended the bytecode compiler to track the start line in the
	generated information, and modified the bytecode execution to
	recompile an object if the location as per the calling context doesn't
	match the location saved in the bytecode. This part could be optimized
	more by using more memory to keep all possibilities which occur
	around, or by just adjusting the location information instead of a
	total recompile.

	Reworked the handling of literal command arguments in bytecode to be
	saved (compiler) and used (execution) per command (See the
	TCL_INVOKE_STK* instructions), and not per the whole bytecode. This,
	and the previous change remove the problems with location data caused
	by literal sharing (across whole files, but also proc bodies).
	Simplified the associated datastructures (ExtIndex is gone, as is the
	function EnterCmdWordIndex).

	The last change causes the hashtable 'lineLABCPtr' to be state which
	has to be kept per coroutine, like the CmdFrame stack. Reworked the
	coroutine support code to create, delete and switch the information as
	needed. Further reworked the tailcall command as well, it has to pop
	its own arguments when run in a bytecode context to keep a proper
	stack in 'lineLABCPtr'.

	Fixed the mishandling of line information in the NRE-enabled 'for' and
	'while' commands introduced when both were made to share their
	iteration callbacks without taking into account that the loop body is
	found in different words of the command. Introduced a separate data
	structure to hold all the callback information, as we went over the
	limit of 4 direct client-data values for NRE callbacks.

	The above fixes [Bug 1605269].

	* generic/tclCompile.c: [Bug 2802881]: The value stashed in
	* generic/tclProc.c:    iPtr->compiledProcPtr when compiling a proc
	* tests/execute.test:   survives too long. We only need it there long
	enough for the right TclInitCompileEnv() call to re-stash it into
	envPtr->procPtr.  Once that is done, the CompileEnv controls.  If we
	let the value of iPtr->compiledProcPtr linger, though, then any other
	bytecode compile operation that takes place will also have its
	CompileEnv initialized with it, and that's not correct.  The value is
	meant to control the compile of the proc body only, not other compile

	formats of really big integers.  Also added protections so that
	[format]s that would produce results overflowing the maximum string
	length of Tcl values throw a normal Tcl error instead of a panic.

	* generic/tclStringObj.c:	[Bug 2803109]: Corrected failures to
	deal with the "pure unicode" representation of an empty string.
	Thanks to Julian Noble for reporting the problem.

2006-06-09  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclGetDate.y: Fixed a thread safety bug in the generated
	* library/clock.tcl:    Bison parser (needed a %pure-parser
	* tests/clock.test:     declaration to avoid static variables).
				Discovered that the %pure-parser declaration
	                        allowed for returning the Bison error message
	                        to the Tcl caller in the event of a syntax
	                        error, so did so.
	* generic/tclDate.c: bison 2.3

2006-06-08  Kevin B. Kenny  <kennykb@acm.org>

	* library/tzdata/Asia/Dhaka: New DST rule for Bangladesh. (Olson's
	tzdata2009i.)

2009-06-08  Donal K. Fellows  <dkf@users.sf.net>

	* doc/copy.n: Fix error in example spotted by Venkat Iyer.

2009-06-02  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c: Replace dynamically-initialized table with a
	table of static constants in the lookup table for exponent operator
	computations that fit in a 64 bit integer result.

	* generic/tclExecute.c: [Bug 2798543]: Corrected implementations and
	selection logic of the INST_EXPON instruction.

2009-06-01  Don Porter  <dgp@users.sourceforge.net>

	* tests/expr.test:      [Bug 2798543]: Added many tests demonstrating
	the broken cases.

2009-05-29  Andreas Kupries  <andreask@activestate.com>

	* library/platform/platform.tcl: Fixed handling of cpu ia64,
	* library/platform/pkgIndex.tcl: taking ia64_32 into account
	* unix/Makefile.in: now. Bumped version to 1.0.5. Updated the
	* win/Makefile.in: installation commands.

2009-05-26 Alexandre Ferrieux  <ferrieux@users.sourceforge.net>

	* doc/expr.n: Fixed documentation of the right-associativity of
	the ** operator. (spotted by kbk)

2009-05-14  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOOInfo.c (InfoObjectNsCmd): Added introspection mechanism
	for finding out what an object's namespace is. Experience suggests
	that it is just too useful to be able to do without it.

2009-05-12  Donal K. Fellows  <dkf@users.sf.net>

	* doc/vwait.n: Added more words to make it clear just how bad it is to
	nest [vwait]s.

	* compat/mkstemp.c: Add more headers to make this file build on IRIX
	6.5. Thanks to Larry McVoy for this.

2009-05-08  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOO.c (TclNRNewObjectInstance):  [Bug 2414858]: Add a
	* generic/tclBasic.c (TclPushTailcallPoint): marker to the stack of
	NRE callbacks at the right point so that tailcall works correctly in a
	constructor.

	* tests/exec.test (cat): [Bug 2788468]: Adjust the scripted version of
	cat so that it does not perform transformations on the data it is
	working with, making it more like the standard Unix 'cat' program.

2009-05-07  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclObj.c (Tcl_GetCommandFromObj): [Bug 2785893]: Ensure that
	a command in a deleted namespace can't be found through a cached name.

	* generic/tclBasic.c:    Let coroutines start with a much smaller
	* generic/tclCompile.h:  stack: 200 words (previously was 2000, the
	* generic/tclExecute.c:  same as interps).

2009-05-07  Donal K. Fellows  <dkf@users.sf.net>

	* tests/env.test (printenvScript, env-4.3, env-4.5): [Bug 1513659]:
	* tests/exec.test (exec-2.6): These tests had subtle dependencies on
	being on platforms that were either ISO 8859-1 or UTF-8. Stabilized
	the results by forcing the encoding.

2009-05-06  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c:	[Bug 2582327]: Improve overflow error message

	Issue spotted by Don Porter.

2009-05-03  Donal K. Fellows  <dkf@users.sf.net>

	* doc/Tcl.n: [Bug 2538432]: Clarified exact treatment of ${arr(idx)}
	form of variable substitution. This is not a change of behavior, just
	an improved description of the current situation.

2009-04-30  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c (TclObjInvoke): [Bug 2486550]: Make sure that a

2009-05-01  Jan Nijtmans <nijtmans@users.sf.net>

	* win/configure.in   Fix 64-bit detection for zlib on Win64

2009-04-27  Donal K. Fellows  <dkf@users.sf.net>

	* doc/concat.n (EXAMPLES): [Bug 2780680]: Rewrote so that the spacing
	of result messages is correct. (The exact way they were wrong was
	different when rendered through groff or as HTML, but it was still
	wrong both ways.)

2009-04-27  Jan Nijtmans <nijtmans@users.sf.net>

	* generic/tclIndexObj.c:  Reset internal INTERP_ALTERNATE_WRONG_ARGS
	* generic/tclIOCmd.c      flag inside the Tcl_WrongNumArgs function,
	                          so the caller no longer has to do the reset.

2009-04-11  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOOMethod.c (InvokeForwardMethod): Clarify the resolution
	behaviour of the name of the command that is forwarded to: it's now
	resolved using the object's namespace as context, which is much more
	useful than the previous (somewhat random) behaviour of using the
	caller's current namespace.

2009-04-10  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* library/http/http.tcl:     Improved HTTP/1.1 support and added
	* library/http/pkgIndex.tcl: specific HTTP/1.1 testing to ensure

	* tests/httpd11.test:        modes (normal, -channel and -handler)
	* makefiles:                 package version set to 2.8.0

	* macosx/tclMacOSXNotify.c:	add CFRunLoop based Tcl_Sleep() and

	* unix/configure:		autoconf-2.59
	* unix/tclConfig.h.in:		autoheader-2.59

	* win/Makefile.in:

2009-04-07  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c:	Correction so that value of

	claims.

2009-04-04  Donal K. Fellows  <dkf@users.sf.net>

	* doc/vwait.n: [Bug 1910136]: Extend description and examples to make

	* generic/tclPathObj.c (TclPathPart): [Bug 2710920]: TclPathPart()
	* tests/fileName.test:	was computing the wrong results for both [file

2009-03-25  Jan Nijtmans  <nijtmans@users.sf.net>

	* doc/tclsh.1:		 Bring doc and tools in line with

2009-03-25  Donal K. Fellows  <dkf@users.sf.net>

2009-03-24  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOOBasic.c (TclOOSelfObjCmd): [Bug 2704302]: Make 'self

	* generic/tclVar.c (Tcl_UpvarObjCmd): [Bug 2673163] (ferrieux)
	* generic/tclProc.c (TclObjGetFrame): Make the upvar command more able

2009-03-22  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c: [Bug 2502037]: NR-enable the handling of unknown
	commands.

2009-03-21  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:   Fixed "leaks" in aliases, imports and
	* generic/tclInt.h:     ensembles. Only remaining known leak is in
	* generic/tclInterp.c:  ensemble unknown dispatch (as it not
	* generic/tclNamesp.c:  NR-enabled)
	* tests/tailcall.test:

	* tclInt.h: comments

	* tests/tailcall.test: Added tests to show that [tailcall] does not
	currently always execute in constant space: interp-alias, ns-imports
	and ensembles "leak" as of this commit.

	* tests/nre.test: [foreach] has been NR-enabled for a while, the test
	was marked 'knownBug': unmark it.

	* generic/tclBasic.c:   Fix for (among others) [Bug 2699087]
	* generic/tclCmdAH.c:   Tailcalls now perform properly even from
	* generic/tclExecute.c: within [eval]ed scripts.
	* generic/tclInt.h:     More tests missing, as well as proper
	exploration and testing of the interaction with "redirectors" like
	interp-alias (suspect that it does not happen in constant space)
	and pure-eval commands.

	* generic/tclExecute.c: Proper fix for [Bug 2415422]. Reenabled
	* tests/nre.test:       the failing assertion that was disabled on
	2008-12-18: the assertion is correct, the fault was in the
	management of expansions.

	* generic/tclExecute.c:  Fix both test and code for tailcall
	* tests/tailcall.test:   from within a compiled [eval] body.

	* tests/tailcall.test: Slightly improved tests

2009-03-20  Don Porter  <dgp@users.sourceforge.net>

	* tests/stringObj.test:         [Bug 2597185]: Test stringObj-6.9
	checks that Tcl_AppendStringsToObj() no longer crashes when operating
	on a pure unicode value.

	* generic/tclExecute.c (INST_CONCAT1):  [Bug 2669109]: Panic when
	appends overflow the max length of a Tcl value.

2009-03-19  Miguel Sofer  <msofer@users.sf.net>

	* generic/tcl.h:
	* generic/tclInt.h:
	* generic/tclBasic.c:
	* generic/tclExecute.c:
	* generic/tclNamesp.c (Tcl_PopCallFrame): Rewritten tailcall
	implementation, ::unsupported::atProcExit is (temporarily?) gone. The
	new approach is much simpler, and also closer to being correct. This
	commit fixes [Bug 2649975] and [Bug 2695587].

	* tests/coroutine.test:    Moved the tests to their own files,
	* tests/tailcall.test:     removed the unsupported.test. Added
	* tests/unsupported.test:  tests for the fixed bugs.

2009-03-19  Donal K. Fellows  <dkf@users.sf.net>

	* doc/tailcall.n: Added documentation for tailcall command.

2009-03-18  Don Porter  <dgp@users.sourceforge.net>

	* win/tclWinFile.c (TclpObjNormalizePath):	[Bug 2688184]:
	Corrected Tcl_Obj leak. Thanks to Joe Mistachkin for detection and
	patch.

	* generic/tclVar.c (TclLookupSimpleVar):	[Bug 2689307]: Shift
	all calls to Tcl_SetErrorCode() out of TclLookupSimpleVar and onto its
	callers, where control with TCL_LEAVE_ERR_MSG flag is more easily
	handled.

2009-03-16  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdMZ.c (TryPostBody): [Bug 2688063]: Extract information
	from list before getting rid of last reference to it.

2009-03-15  Joe Mistachkin  <joe@mistachkin.com>

	* generic/tclThread.c: Modify fix for TSD leak to match Tcl 8.5
	* generic/tclThreadStorage.c: (and prior) allocation semantics. [Bug
	2687952]

2009-03-15  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclThreadStorage.c (TSDTableDelete):	[Bug 2687952]: Ensure
	* generic/tclThread.c (Tcl_GetThreadData):	that structures in
	Tcl's TSD system are all freed. Use the correct matching allocator.

	* generic/tclPosixStr.c (Tcl_SignalId,Tcl_SignalMsg): [Patch 1513655]:
	Added support for SIGINFO, which is present on BSD platforms.

2009-03-14  Donal K. Fellows  <dkf@users.sf.net>

	* unix/tcl.pc.in (new file):		[Patch 2243948] (hat0)
	* unix/configure.in, unix/Makefile.in: Added support for reporting
	Tcl's public build configuration via the pkg-config system. TEA is
	still the official mechanism though, in part because pkg-config is not
	universally supported across all Tcl's supported platforms.

2009-03-11  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c (TclNRCoroutineObjCmd): fix Tcl_Obj leak.
	Diagnosis and fix thanks to GPS.

2009-03-09  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdMZ.c (Tcl_TryObjCmd, TclNRTryObjCmd): Moved the
	implementation of [try] from Tcl code into C. Still lacks a bytecode
	version, but should be better than what was before.

2009-03-04  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclZlib.c (TclZlibCmd): Checksums are defined to be unsigned
	32-bit integers, use Tcl_WideInt to pass to scripts. [Bug 2662434]
	(ZlibStreamCmd, ChanGetOption): A few other related corrections.

2009-02-27  Jan Nijtmans  <nijtmans@users.sf.net>

	* generic/tcl.decls:    [Bug 218977]: Tcl_DbCkfree needs return value
	* generic/tclCkalloc.c
	* generic/tclDecls.h    (regenerated)
	* generic/tclInt.decls: don't use CONST84/CONST86 here
	* generic/tclCompile.h: don't use CONST86 here, comment fixing.
	* generic/tclIO.h:      don't use CONST86 here, comment fixing.
	* generic/tclIntDecls.h (regenerated)

2009-02-25  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclUtil.c (TclStringMatchObj):	[Bug 2637173]: Revised
	the branching on the strObj->typePtr so that untyped values get
	converted to the "string" type and pass through the Unicode matcher.
	[Bug 2613766]: Also added checks to only perform "bytearray"
	optimization on pure bytearray values.

	* generic/tclCmdMZ.c:	Since Tcl_GetCharLength() has its own
	* generic/tclExecute.c:	optimizations for the tclByteArrayType, stop
	having the callers do them.

2009-02-24  Donal K. Fellows  <dkf@users.sf.net>

	* doc/clock.n, doc/fblocked.n, doc/format.n, doc/lsort.n,
	* doc/pkgMkIndex.n, doc/regsub.n, doc/scan.n, doc/tclvars.n:
	General minor documentation improvements.

	* library/http/http.tcl (geturl, Eof): Added support for 8.6's built
	in zlib routines.

2009-02-22  Alexandre Ferrieux  <ferrieux@users.sourceforge.net>

	* tests/lrange.test:	Revert commits of 2008-07-23. Those were speed
	* tests/binary.test:	tests, that are inherently brittle.

2009-02-21  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c:	Several revisions to the shimmering
	patterns between Unicode and UTF string reps.  Most notably the
	call: objPtr = Tcl_NewUnicodeObj(...,0); followed by a loop of calls:
	Tcl_AppendUnicodeToObj(objPtr, u, n); will now grow and append to
	the Unicode representation.  Before this commit, the sequence would
	convert each append to UTF and perform the append to the UTF rep.
	This is puzzling and likely a bug.  The performance of [string map]
	is significantly improved by this change (according to the MAP
	collection of benchmarks in tclbench).  Just in case there was some
	wisdom in the old ways that I missed, I left in the ability to restore
	the old patterns with a #define COMPAT 1 at the top of the file.

2009-02-20  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclPathObj.c:	Fixed mistaken logic in TclFSGetPathType()
	* tests/fileName.test:	that assumed (not "absolute" => "relative").
	This is a false assumption on Windows, where "volumerelative" is
	another possibility.  [Bug 2571597]

2009-02-18  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c:	Simplify the logic of the
	Tcl_*SetObjLength() routines.

	* generic/tclStringObj.c:	Rewrite GrowStringBuffer() so that it
	has parallel structure with GrowUnicodeBuffer().  The revision permits
	allocation attempts to continue all the way up to failure, with no
	gap. It also directly manipulates the String and Tcl_Obj internals
	instead of inefficiently operating via Tcl_*SetObjLength() with all of
	its extra protections and underdocumented special cases.

	* generic/tclStringObj.c:	Another round of simplification on
	the allocation macros.

2009-02-17  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tcl.m4, win/configure: Check if cl groks _WIN64 already to
	avoid CC manipulation that can screw up later configure checks.
	Use 'd'ebug runtime in 64-bit builds.

2009-02-17  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c:	Pare back the length of the unicode
	array in a non-extended String struct to one Tcl_UniChar, meant to
	hold the terminating NUL character.  Non-empty unicode strings are
	then stored by extending the String struct by stringPtr->maxChars
	additional slots in that array with sizeof(Tcl_UniChar) bytes per
	slot. This revision makes the allocation macros much simpler.

	* generic/tclStringObj.c:	Factor out common GrowUnicodeBuffer()
	and solve overflow and growth algorithm fallbacks in it.

	* generic/tclStringObj.c:	Factor out common GrowStringBuffer().

	* generic/tclStringObj.c:	Convert Tcl_AppendStringsToObj into
	* tests/stringObj.test:		a radically simpler implementation
	where we just loop over calls to Tcl_AppendToObj.  This fixes [Bug
	2597185].  It also creates a *** POTENTIAL INCOMPATIBILITY *** in
	that T_ASTO can now allocate more space than is strictly required,
	like all the other Tcl_Append* routines.  The incompatibility was
	detected by test stringObj-6.5, which I've updated to reflect the
	new behavior.

	* generic/tclStringObj.c:	Revise buffer growth implementation
	in ExtendStringRepWithUnicode.  Use cheap checks to determine that
	no reallocation is necessary without cost of computing the precise
	number of bytes needed.  Also make use of the string growth algortihm
	in the case of repeated appends.

2009-02-16  Jan Nijtmans  <nijtmans@users.sf.net>

	* generic/tclZlib.c:	hack needed for official zlib1.dll build.
	* win/configure.in:	fix [Feature Request 2605263] use official
	* win/Makefile.in:	zlib build.
	* win/configure:	(regenerated)
	* compat/zlib/zdll.lib:	new files
	* compat/zlib/zlib1.dll:

	* win/Makefile.in:  fix [Bug 2605232] tdbc doesn't build when
	Tcl is compiled with --disable-shared.

2009-02-15  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c:	Added protections from invalid memory
	* generic/tclTestObj.c:		accesses when we append (some part of)
	* tests/stringObj.test:		a Tcl_Obj to itself.  Added the
	appendself and appendself2 subcommands to the [teststringobj] testing
	command and added tests to the test suite.  [Bug 2603158]

	* generic/tclStringObj.c:	Factor out duplicate code from
	Tcl_AppendObjToObj.

	* generic/tclStringObj.c:	Replace the 'size_t uallocated' field
	of the String struct, storing the number of bytes allocated to store
	the Tcl_UniChar array, with an 'int maxChars' field, storing the
	number of Tcl_UniChars that may be stored in the allocated space.
	This reduces memory requirement a small bit, and makes some range
	checks simpler to code.
	* generic/tclTestObj.c:	Replace the [teststringobj ualloc] testing
	* tests/stringObj.test:	command with [teststringobj maxchars] and
	update the tests.

	* generic/tclStringObj.c:	Removed limitation in
	Tcl_AppendObjToObj where the char length of the result was only
	computed if the appended string was all single byte characters.
	This limitation was in place to dodge a bug in Tcl_GetUniChar.
	With that bug gone, we can take advantage of always recording the
	length of append results when we know it.

2009-02-14  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c:	Revisions so that we avoid creating
	the strange representation of an empty string with
	objPtr->bytes == NULL and stringPtr->hasUnicode == 0.  Instead in
	the situations where that was being created, create a traditional
	two-legged stork representation (objPtr->bytes = tclEmptyStringRep
	and stringPtr->hasUnicode = 1).  In the situations where the strange
	rep was treated differently, continue to do so by testing
	stringPtr->numChars == 0 to detect it.  These changes make the code
	more conventional so easier for new maintainers to pick up.  Also
	sets up further simplifications.

	* generic/tclTestObj.c:	Revise updates to [teststringobj] so we don't
	get blocked by MODULE_SCOPE limits.

2009-02-12  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c:	Rewrites of the routines
	Tcl_GetCharLength, Tcl_GetUniChar, Tcl_GetUnicodeFromObj,
	Tcl_GetRange, and TclStringObjReverse to use the new macro, and
	to more simply and clearly split the cases depending on whether
	a valid unicode rep is present or needs to be created.
	New utility routine UnicodeLength(), to compute the length of unicode
	buffer arguments when no length is passed in, with built-in
	overflow protection included.  Update three callers to use it.

	* generic/tclInt.h:	New macro TclNumUtfChars meant to be a faster
	replacement for a full Tcl_NumUtfChars() call when the string has all
	single-byte characters.

	* generic/tclStringObj.c:	Simplified Tcl_GetCharLength by
	* generic/tclTestObj.c:		removing code that did nothing.
	Added early returns from Tcl_*SetObjLength when the desired length
	is already present; adapted test command to the change.

	* generic/tclStringObj.c:	Re-implemented AppendUtfToUnicodeRep
	so that we no longer pass through Tcl_DStrings which have their own
	sets of problems when lengths overflow the int range.  Now AUTUR and
	FillUnicodeRep share a common core routine.

2009-02-12  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOODefineCmds.c (TclOOGetDefineCmdContext): Use the
	correct field in the Interp structure for retrieving the frame to get
	the context object so that people can extend [oo::define] without deep
	shenanigans. Bug found by Federico Ferri.

2009-02-11  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c:	Re-implemented AppendUnicodeToUtfRep
	so that we no longer pass through Tcl_DStrings which have their own
	sets of problems when lengths overflow the int range.  Now AUTUR and
	UpdateStringOfString share a common core routine.

	* generic/tclStringObj.c:	Changed type of the 'allocated' field
	* generic/tclTestObj.c:		of the String struct (and the
	TestString counterpart) from size_t to int since only int values are
	ever stored in it.

2009-02-10  Jan Nijtmans  <nijtmans@users.sf.net>

2009-02-10  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclObj.c (Tcl_GetString):	Added comments and validity

	Restrict AppendUtfToUtfRep to non-negative length appends.
	Convert all Tcl_InvalidateStringRep() calls into macros.
	Simplify Tcl_AttemptSetObjLength by removing unreachable code.
	Simplify SetStringFromAny() by removing unreachable and duplicate code.

2009-02-07  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclZlib.c (TclZlibCmd): [Bug 2573172]: Ensure that when

	produced. This gives a better experience when using the command
	interactively.

2009-02-05  Joe Mistachkin  <joe@mistachkin.com>

	* generic/tclInterp.c: Fix argument checking for [interp cancel]. [Bug

	other platforms).

2009-02-05  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdMZ.c (StringIndexCmd, StringRangeCmd, StringLenCmd):
	Simplify the implementation of some commands now that the underlying
	string API knows more about bytearrays.

	* generic/tclExecute.c (TclExecuteByteCode): [Bug 2568434]: Make sure
	that INST_CONCAT1 will not lose string reps wrongly.

	* generic/tclStringObj.c (Tcl_AppendObjToObj): Special-case the
	appending of one bytearray to another, which can be extremely rapid.
	Part of scheme to address [Bug 1665628] by making the basic string
	operations more efficient on byte arrays.
	(Tcl_GetCharLength, Tcl_GetUniChar, Tcl_GetRange): More special casing
	work for bytearrays.

2009-02-04  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c: Added overflow protections to the
	AppendUtfToUtfRep routine to either avoid invalid arguments and
	crashes, or to replace them with controlled panics.  [Bug 2561794]

	* generic/tclCmdMZ.c:	Prevent crashes due to int overflow of the

	* generic/tclObj.c (tclCmdNameType): [Bug 2558422]: Corrected the type
	of this structure so that extensions that write it (yuk!) will still
	be able to function correctly.

2009-02-03  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c (SetUnicodeObj):	Corrected failure of
	Tcl_SetUnicodeObj() to panic on a shared object.  [Bug 2561488].  Also
	factored out common code to reduce duplication.

	* generic/tclObj.c (Tcl_GetStringFromObj): Reduce code duplication.

2009-02-02  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInterp.c:	Reverted the conversion of [interp] into an
	* tests/interp.test:	ensemble.  Such conversion is not necessary
	* tests/nre.test:	(or even all that helpful) in the NRE-enabling
	of [interp invokehidden], and it has other implications -- including
	significant forkage of the 8.5 and 8.6 implementations -- that are

	* generic/tclStringObj.c (STRING_NOMEM):  [Bug 2494093]: Add missing
	cast of NULL to (char *) that upsets some compilers.

	* generic/tclStringObj.c (Tcl_(Attempt)SetObjLength):	[Bug 2553906]:
	Added protections against callers asking for negative lengths.  It is
	likely when this happens that an integer overflow is to blame.

2009-02-01  David Gravereaux <davygrvy@pobox.com>

	* win/makefile.vc: Allow nmake flags such as -a (rebuild all) to pass
	down to the pkgs targets, too.

2009-01-30  Donal K. Fellows  <dkf@users.sf.net>

	* doc/chan.n: [Bug 1216074]: Added another extended example.

	* generic/tclOODecls.h (Tcl_OOInitStubs): [Bug 2537839]: Make the
	declaration of this macro work correctly in the non-stub case.

2009-01-29  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInterp.c:	Convert the [interp] command into a

	subcommand.

2009-01-29  Donal K. Fellows  <dkf@users.sf.net>

2009-01-28  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclBasic.c (TclInvokeObjectCommand): Made this understand

2009-01-21  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIORChan.c (ReflectClose): Fix for [Bug 2458202].
	* generic/tclIORTrans.c (ReflectClose): Closing a channel may supply
	NULL for the 'interp'. Test for finalization needs to be different,
	and one place has to pull the interp out of the channel instead.

2009-01-21  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c: New fix for [Bug 2494093] replaces the
	flawed attempt committed 2009-01-09.

2009-01-19  Kevin B. Kenny  <kennykb@acm.org>

	* unix/Makefile.in: Added a CONFIG_INSTALL_DIR parameter so that
	* unix/tcl.m4:      distributors can control where tclConfig.sh goes.
	Made the installation of 'ldAix' conditional upon actually being on an
	AIX system. Allowed for downstream packagers to customize
	SHLIB_VERSION on BSD-derived systems. Thanks to Stuart Cassoff for
	[Patch 907924].
	* unix/configure: Autoconf 2.59

2009-01-19  David Gravereaux <davygrvy@pobox.com>

	* win/build.vc.bat: Improved tools detection and error message
	* win/makefile.vc: Reorganized the $(TCLOBJ) file list into seperate
	parts for easier maintenance. Matched all sources built using -GL to
	both $(lib) and $(link) to use -LTCG and avoid a warning message.
	Addressed the over-building nature of the htmlhelp target by moving
	from a pseudo target to a real target dependent on the entire docs/
	directory contents.
	* win/nmakehlp.c: Removed -g option and GrepForDefine() func as it
	isn't being used anymore. The -V option method is much better.

2009-01-16  Don Porter  <dgp@users.sourceforge.net>

	* generic/tcl.h:	Bump patchlevel to 8.6b1.1 to distinguish
	* library/init.tcl:	CVS snapshots from the 8.6b1 and 8.6b2 releases
	* unix/configure.in:	and to deal with the fact that the 8.6b1
	* win/configure.in:	version of init.tcl will not [source] in the
	HEAD version of Tcl.

	* unix/configure:	autoconf-2.59
	* win/configure:

2009-01-14  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken):	Reverted most
	of the substance of my 2009-01-12 commit. NULLing the objProc field of
	a Command when deleting it is important so that tests for certain
	classes of commands don't return false positives when applied to
	deleted command tokens. Overall change is now just replacement of a
	false comment with a true one.

2009-01-13  Jan Nijtmans  <nijtmans@users.sf.net>

	* unix/tcl.m4: fix [tcl-Bug 2502365] Building of head on HPUX is

2009-01-13  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdMZ.c (Tcl_ThrowObjCmd):	Move implementation of [throw]
	* library/init.tcl (throw):		to C from Tcl.

2009-01-12  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken): One consequence of
	the NRE rewrite is that there are now situations where a NULL objProc
	field in a Command struct is perfectly normal. Removed an outdated
	comment in Tcl_DeleteCommandFromToken that claimed we use
	cmdPtr->objPtr==NULL as a test of command validity. In fact we use
	cmdPtr->flags&CMD_IS_DELETED to perform that test. Also removed the
	setting to NULL, since any extension following the advice of the old
	comment is going to be broken by NRE anyway, and needs to shift to
	flag-based testing (or stop intruding into such internal matters).
	Part of [Bug 2486550].

2009-01-09  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c (STRING_SIZE): Corrected failure to limit
	memory allocation requests to the sizes that can be supported by Tcl's
	memory allocation routines. [Bug 2494093]

2009-01-09  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclNamesp.c (NamespaceEnsembleCmd): Error out when someone
	gives wrong # of args to [namespace ensemble create]. [Bug 1558654]

2009-01-08  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c (STRING_UALLOC):  Added missing parens
	required to get correct results out of things like
	STRING_UALLOC(num + append). [Bug 2494093]

2009-01-08  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclDictObj.c, generic/tclIndexObj.c, generic/tclListObj.c,
	* generic/tclObj.c, generic/tclStrToD.c, generic/tclUtil.c,
	* generic/tclVar.c: Generate errorcodes for the error cases which
	approximate to "I can't interpret that string as one of those" and
	"You gave me the wrong number of arguments".

2009-01-07  Donal K. Fellows  <dkf@users.sf.net>

	* doc/dict.n: Added more examples. [Tk Bug 2491235]

	* tests/oo.test (oo-22.1): Adjusted test to be less dependent on the
	specifics of how [info frame] reports general frame information, and
	instead to focus on what methods add to it; that's really what the
	test is about anyway.

2009-01-06  Don Porter	<dgp@users.sourceforge.net>

	* tests/stringObj.test:	Revise tests that demand a NULL Tcl_ObjType
	in certain values to construct those values with [testdstring] so
	there's no lack of robustness depending on the shimmer history of
	shared literals.

2009-01-06  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclDictObj.c (DictIncrCmd): Corrected twiddling in internals
	of dictionaries so that literals can't get destroyed.

	* tests/expr.test: Eliminate non-ASCII char. [Bug 2006879]

	* generic/tclOOInfo.c (InfoObjectMethodsCmd,InfoClassMethodsCmd): Only
	delete pointers that were actually allocated! [Bug 2489836]

	* generic/tclOO.c (TclNRNewObjectInstance, Tcl_NewObjectInstance):
	Perform search for existing commands in right context. [Bug 2481109]

2009-01-05  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdMZ.c (TclNRSourceObjCmd): Make implementation of the
	* generic/tclIOUtil.c (TclNREvalFile):    [source] command be NRE
	enabled so that [yield] inside a script sourced in a coroutine can
	work. [Bug 2412068]

2009-01-04  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdAH.c: Tidy up spacing and code style.

2009-01-03  Kevin B. Kenny <kennykb@acm.org>:

	* library/clock.tcl (tcl::clock::add): Fixed error message formatting
	in the case where [clock add] is presented with a bad switch.
	* tests/clock.test (clock-65.1) Added a test case for the above
	problem [Bug 2481670].

2009-01-02  Donal K. Fellows  <dkf@users.sf.net>

	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Force the use of the compatibility
	version of mkstemp() on IRIX. [Bug 878333]
	* unix/configure.in, unix/Makefile.in (mkstemp.o):
	* compat/mkstemp.c (new file): Added a compatibility implementation of
	the mkstemp() function, which is apparently needed on some platforms.
	[Bug 741967]

2008-12-31  Don Porter	<dgp@users.sourceforge.net>

	* unix/Makefile.in:	Set TCLLIBPATH in SHELL_ENV so that targets
	like `make shell` have access to builds of bundled packages.

2008-12-28  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclZlib.c (Tcl_ZlibStreamPut): Plug a memory leak.

2008-12-27  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclZlib.c (ZlibStreamCmd): Fix compilation consistency. [Bug
	* generic/tcl.decls:		     2470237]

	* generic/tclZlib.c (Tcl_ZlibStreamGet): Corrected the semantics of
	this function to be useful to the PNG implementation. If the argument
	object is empty, this gives the previous semantics.
	(Tcl_ZlibStreamChecksum): Corrected name to be less misleading; it
	only produced Adler-32 checksums when the stream was processing the
	right type of compressed data format.
	(Tcl_ZlibAdler32, Tcl_ZlibCRC32): Corrected types so that they work
	naturally with the results of Tcl_GetByteArrayFromObj().
	*** POTENTIAL INCOMPATIBILITY *** for all above changes, but very
	unlikely to be difficult for anyone to deal with.

2008-12-26  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tcl.decls: Tidy up the commenting style, adding markers for
	each of the big release points under TCT stewardship and noting the
	general purpose of each TIP that added C API. Overall effect is to
	make this file much more informative to read without having to spend
	effort correlating with TIPs and ChangeLogs.

2008-12-23  Jan Nijtmans  <nijtmans@users.sf.net>

2008-12-22  Pat Thoyts  <patthoyts@users.sourceforge.net>

	*** 8.6b1 TAGGED FOR RELEASE ***

	* win/makefile.vc: Ensure pkgs directories are suitable and quote the
			   paths. [Bug 2458395]

2008-12-22  Joe Mistachkin  <joe@mistachkin.com>

	* tools/man2help2.tcl: Added support for "\(mi" nroff macro. [Bug
	2330040]

2008-12-22  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/makefile.vc: Support the pkgs tree in the NMAKE builds.

2008-12-21  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in:	Fix broken build of bundled packages when path
				to build dir contains spaces by switching to
				relative paths to toplevel build dir.

	* unix/configure.in:	Preserve configure environment variables for
				sub-configures of bundled packages; reuse
				configure cache file for sub-configures.

	* unix/configure:	autoconf-2.59

2008-12-21  Donal K. Fellows  <dkf@users.sf.net>

	* doc/TclZlib.3: Fix minor typo. [Bug 2455165]

2008-12-20  Kevin B. Kenny  <kennykb@acm.org>

	* win/Makefile.in:	Renamed the static library libtcl86s.a to
	* win/configure.in:	have a name distinct from the import library
				libtcl86.a. This renaming dodges an ancient
				bug in the Makefile revealed by the last
				commit where the $(TCL_LIB_FILE) rule can
				fire to try to build the static library in a
				--enable-shared build (and create a static
				library that subsequently fails to link).
				Revised the zlib objects so that they are
				built directly into the build dir, without
				building an intermediate static library.
				*** POTENTIAL INCOMPATIBILITY *** for
				embedders who link to the static library, but
				I couldn't figure out how to sort this out
				any other way.
	* win/configure:	Autoconf 2.59

2008-12-20  Donal K. Fellows  <dkf@users.sf.net>

	* win/Makefile.in: Minor updates to make building work better with

	CloseWrite, CloseChannelPart, new flag CHANNEL_CLOSEDWRITE.

	* tests/chanio.test (chanio-28.[67]): Reactivated these tests.
	Replaced tclsh -> [interpreter] to get correct executable for the pipe
	process, and added after cancel to kill the fail timers when we are

	this correctly.

2008-12-18  Don Porter	<dgp@users.sourceforge.net>

	* tests/chanio.test:	Replaced [chan event] handlers that returned
	TCL_RETURN return code, with more conventional ones that return TCL_OK

				objects leaves temporary files on windows.

2008-11-12  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* tests/registry.test: Use HKCU to avoid requiring admin access for
	registry testing on Vista/Server2008

2008-11-11  Jan Nijtmans  <nijtmans@users.sf.net>

	* generic/tclNamesp.c:	Eliminate warning: passing arg 4 of
				Tcl_SplitList from incompatible pointer type.
	* win/tcl.m4:	Reverted change from 2008-11-06 (was under the
			impression that "-Wno-implicit-int" added an extra
			warning)
	* win/configure: (regenerated)
	* unix/tcl.m4:	Use -O2 as gcc optimization compiler flag, and get rid
			of -Wno-implicit-int for UNIX.
	* unix/configure: (regenerated)

2008-11-10  Andreas Kupries  <andreask@activestate.com>

	* doc/platform_shell.n: Fixed [Bug 2255235], reported by Ulrich
	* library/platform/pkgIndex.tcl: Ring <uring@users.sourceforge.net>.
	* library/platform/shell.tcl: Updated the LOCATE command in the
	* library/tm.tcl:   package 'platform::shell' to handle the new form
	* unix/Makefile.in: of 'provide' commands generated by tm.tcl. Bumped
	* win/Makefile.in:  package to version 1.1.4. Added cross-references
	to the relevant parts of the code to avoid future desynchronization.

2008-11-07  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* generic/tclInt.h:    Applied [Patch 2215022] from Duoas to clean up
	* generic/tclBinary.c: the binary ensemble initiailization code.
	* generic/tclNamesp.c: Extends the TclMakeEnsemble to do
	* doc/ByteArrObj.3:    sub-ensembles from tables.

2008-11-06  Jan Nijtmans  <nijtmans@users.sf.net>

	* win/tcl.m4:	    Add "-Wno-implicit-int" flag for gcc, as on UNIX
	* win/configure:    (regenerated)
	* generic/tclIO.c:  Eliminate an 'array index out of bounds' warning
			    on HP-UX.

2008-11-04  Jeff Hobbs	<jeffh@ActiveState.com>

	* generic/tclPort.h: Remove the ../win/ header dir as the build system
	already has it, and it confuses builds when used with private headers
	installed.

2008-11-01  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOO.h (TCLOO_VERSION): Bump version of TclOO.

2008-10-31  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOOBasic.c (TclOONRUpcatch): Reworked the code that does
	* generic/tclOO.c (InitFoundation):	 class constructor handling so
	that it is more robust and runs the constructor call in the context of
	the caller of the class's constructor method. Needed because the
	previously used code did not work at all after applying the fix below;
	no Tcl existing command could reliably do what was needed any more.

	* generic/tclOODefineCmds.c (GetClassInOuterContext): Rework and
	factor out the code to resolve class names in definitions so that
	classes are resolved from the perspective of the caller of the
	[oo::define] command, rather than from the oo::define namespace! This
	makes much code simpler by reducing how often fully-qualified names
	are required (previously always in practice, so no back-compat issues
	exist). [Bug 2200824]

	* generic/tclLink.c:

2008-10-27  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclEncoding.c:	Use "iso8859-1" and not "identity" as
	the default and original [encoding system] value. Since "iso8859-1" is
	built in to the C source code for Tcl now, there's no availability
	issue, and it has the good feature of "identity" that we must have
	("bytes in" == "bytes out") without the bad feature of "identity"
	("broken as designed") that makes us want to abandon it. [RFE 2008609]
	*** POTENTIAL INCOMPATIBILITY for older releases of Tclkit and any
	other code expecting a particular value for Tcl's default system
	encoding ***

2008-10-24  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* library/http/http.tcl: Fixed a failure to read SHOUTcast streams
	with the new 2.7 package. Introduced a new intial state as the first
	response may not be HTTP*.

2008-10-17  Donal K. Fellows  <dkf@users.sf.net>

	* doc/*: Many very small formatting fixes.

	preserves the state of the ::errorInfo and ::errorCode variables at
	the start of auto-loading and restores that state before the
	autoloaded command is evaluated. [Bug 2140628]

2008-10-15  Jan Nijtmans  <nijtmans@users.sf.net>

	* generic/tclInt.h:	Add "const" to many internal const tables, so

	suitable for the hard-of-reading. Following discussion on tcl-core.

2008-10-13  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* win/tclWinThrd.c (TclpThreadCreate): We need to initialize the
	thread id variable to 0 as on 64 bit windows this is a pointer sized
	field while windows only fills it with a 32 bit value. The result is
	an inability to join the threads as the ids cannot be matched.

	* generic/tclTest.c (TestNRELevels): Set array to the right size.

2008-10-13  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOOInfo.c (InfoClassDestrCmd): Handle error case.

	* generic/tclTrace.c:	Corrected handling of errors returned by
	variable traces so that the errorInfo value contains the original
	error message. [Bug 2151707]

	* generic/tclVar.c:	Revised implementation of TclObjVarErrMsg so
	that error message construction does not disturb an existing
	iPtr->errorInfo that may be in progress.

	* doc/FileSystem.3:	CONSTified Tcl_FSFileAttrStringsProc
	* generic/tclFCmd.c:	and tclpFileAttrStrings. This allows
	* generic/tclIOUtil.c:	FileSystems to report their attributes
	* generic/tclTest.c:	as const strings, without worrying that
	* unix/tclUnixFCmd.c:	Tcl modifies them (which Tcl should not

	* doc/lset.n:
	* generic/tclListObj.c (TclLsetFlat):

	the list.

2008-10-05  Jan Nijtmans  <nijtmans@users.sf.net>

	* generic/tclInt.decls:	 CONSTified the AuxDataType argument

	This change complies with TIP #27 (even though it only involves
	internal function, so this is not even necessary).

2008-10-05  Donal K. Fellows  <dkf@users.sf.net>

	into an exported command. [Bug 2144595]

	yet. [Bug 2059262]

2008-10-04  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOOInfo.c (GetClassFromObj): Factor out the code to parse
	a Tcl_Obj and get a class. Also make result handling hygienic.
	* generic/tclOOBasic.c (TclOOSelfObjCmd): Better hygiene of results,
	and stop allocating quite so much memory by sharing special "method"
	names.

2008-10-04  Jan Nijtmans  <nijtmans@users.sf.net>

	TIP #195 IMPLEMENTATION

	* generic/tclIndexObj.c (TclGetIndexFromObjList, PrefixMatchObjCmd)

	TIP #265 IMPLEMENTATION

	* generic/tclIndexObj.c (Tcl_ParseArgsObjv, PrintUsage):
	* generic/tcl.h (Tcl_ArgvInfo):	Added function for simple parsing of
	* doc/ParseArgs.3 (new file):	optional arguments to commands. Still
	needs tests and the like. [FRQ 1446696] Note that some of the type
	signatures are changed a bit from the proposed implementation so that
	they better reflect codified good practice for argument order.

2008-10-02  Andreas Kupries  <andreask@activestate.com>

	* tests/info.test (info-23.3): Updated output of the test to handle
	the NRE-enabled eval and the proper propagation of location

	numbers as level argument. [Bug 2134049]

	* tests/info.test (info-22.8): Made pattern for file containing

	during matching. [Bug 2129828]

2008-10-02  Don Porter	<dgp@users.sourceforge.net>

	* generic/tcl.h:	Remove the "result" and "freeProc" fields
	* generic/tclBasic.c:	from the default public declaration of the
	* generic/tclResult.c:	Tcl_Interp struct. Code should no longer
	* generic/tclStubLib.c:	be accessing these fields. Access can be

	case where the combination of number of elements and repeat count
	causes the resulting list to be too large. [Bug 2130992]

	* unix/tclUnixInit.c, win/tclWinInit.c (TclpSetVariables):
	* doc/tclvars.n (tcl_platform): Define what character is used for
	separating PATH-like lists. Forms part of the tcl_platform array.

	* generic/tclOOCall.c (InitCallChain, IsStillValid):
	* tests/oo.test (oo-25.2): Revise call chain cache management so that
	it takes into account class-wide caching correctly. [Bug 2120903]

2008-09-24  Don Porter	<dgp@users.sourceforge.net>

	TIP #323 IMPLEMENTATION (partial)

	* generic/tclOOMethod.c (TclOOSetupVariableResolver, etc):
	* doc/define.n, doc/ooInfo.n, benchmarks/cps.tcl:
	* tests/oo.test (oo-26.*): Allow the declaration of the common

	in using a variable resolver. This makes many class declarations much
	simpler overall, encourages good usage of variable names, and also
	boosts speed a bit.

	* generic/tclOOMethod.c (TclOOGetMethodBody): Factor out the code to
	get the body of a procedure-like method. Reduces the amount of "poking
	inside the abstraction" that is done by the introspection code.

	* generic/tclInt.h: Correct the TclGetLongFromObj, TclGetIntFromObj,
	and TclGetIntForIndexM macros so that they retrieve the longValue

	* library/init.tcl: Export min and max commands from the mathfunc
	namespace. [Bug 2116053]

2008-09-16  Joe Mistachkin  <joe@mistachkin.com>

	* generic/tclParse.c: Move TclResetCancellation to be called on
	returning to level 0, as opposed to it being called on starting a
	substitution at level 0.

2008-09-16  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c: Move TclResetCancellation to be called on

	* generic/tclListObj.c (Tcl_ListObjGetElements): Make this list->dict
	transformation - encountered when using [foreach] with dicts - not as
	expensive as it was before. Spotted by Kieran Elby and reported on
	tcl-core.

2008-09-08  Donal K. Fellows  <dkf@users.sf.net>

	* tests/append.test, appendComp.test, cmdAH.test: Use the powers of
	tcltest2 to make these files simpler.

2008-09-07  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompile.c (TclCompileTokens):
	* generic/tclExecute.c (CompileExprObj): Fix a perf bug (found by Alex
	Ferrieux) where some variables in the LVT where not being accessed by

	* generic/tclExecute.c (CACHE_STACK_INFO):
	* tests/unsupported.test: Restore execEnv's bottomPtr. [Bug 2093188]

2008-09-02  Don Porter	<dgp@users.sourceforge.net>

	* generic/tcl.h:	Stripped "callers" of the _ANSI_ARGS_ macro
	* compat/dirent2.h:	to support a TCL_NO_DEPRECATED build.
	* compat/dlfcn.h:
	* unix/tclUnixPort.h:

	* generic/tcl.h:	Removed the conditional #define of
	_ANSI_ARGS_ that would support pre-prototype C compilers. Since
	_ANSI_ARGS_ is no longer used in tclDecls.h, it's clear no one
	compiling against Tcl 8.5 headers is making use of a -DNO_PROTOTYPES
	configuration.

2008-09-02  Donal K. Fellows  <dkf@users.sf.net>

	* tests/socket.test: Rewrote so as to use tcltest2 better.

	* tests/unsupported.test:

2008-09-01  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOOMethod.c (InvokeProcedureMethod):
	* generic/tclOO.c (ObjectRenamedTrace): Arrange for only methods that
	involve callbacks into the Tcl interpreter to be skipped when the
	interpreter is being torn down. Allows the semantics of destructors in
	a dying interpreter to be more useful when they're implemented in C.

2008-08-29  Donal K. Fellows  <dkf@users.sf.net>

	* unix/Makefile.in: Ensure that all TclOO headers get installed.
	* win/Makefile.in:  [Bug 2082299]

	* doc/tclvars.n, doc/library.n: Ensured that these two manual pages
	properly cross-reference each other. Issue reported on Tcler's Chat.

2008-08-26  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c (InfoCoroutine):
	* tests/unsupported.test: New command that returns the FQN of the
	currently executing coroutine. Lives as infoCoroutine under
	unsupported, but is designed to become a subcommand of [info]

2008-08-23  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c (NRInterpCoroutine): Store the caller's eePtr,
	stop assuming the coroutine is invoked from the same execEnv where it
	was created.

2008-08-24  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdAH.c (TclNRForeachCmd): Converted the [foreach]
	command to have an NRE-aware non-compiled implementation. Part of the
	[Bug 2017632] project. Also restructured the code so as to manage its
	temporary memory more efficiently.

2008-08-23  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:	  Removed unused var; fixed function pointer
	* generic/tclOOInt.h:	  declarations (why did gcc start complaining
	* generic/tclOOMethod.c:  all of a sudden?)
	* generic/tclProc.c:

2008-08-23  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclInt.h (EnsembleImplMap): Added extra field to make it
	* generic/tclNamesp.c (TclMakeEnsemble): easier to build non-recursive
	ensembles in the core.

	* generic/tclDictObj.c (DictForNRCmd): Converted the [dict for]
	command to have an NRE-aware non-compiled implementation. Part of the
	[Bug 2017632] project.

2008-08-22  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:
	* generic/tclExecute.c: Set special errocodes: COROUTINE_BUSY,
	COROUTINE_CANT_YIELD, COROUTINE_ILLEGAL_YIELD.

2008-08-22  Don Porter	<dgp@users.sourceforge.net>

	*** 8.6a2 TAGGED FOR RELEASE ***

	* changes:	Updates for 8.6a2 release.

	* generic/tcl.h:	Drop use of USE_COMPAT85_CONST. That added
	indirection without value. Use -DCONST86="" to engage source compat
	support for code written for 8.5 headers.

	* generic/tclUtil.c (TclReToGlob):	Added missing set of the
	*exactPtr value to really fix [Bug 2065115]. Also avoid possible
	DString overflow.
	* tests/regexpComp.test:	Correct duplicate test names.

2008-08-21  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:	  Previous fix, now done right.

	* generic/tclUtil.c (TclReToGlob):	    translation from exact
	to anywhere-in-string match. [Bug 2065115]

2008-08-21  Don Porter	<dgp@users.sourceforge.net>

	* generic/tcl.h:	Reduced the use of CONST86 and eliminated
	* generic/tcl.decls:	the use of CONST86_RETURN to support source
	code compatibility with Tcl 8.5 on those public routines passing
	(Tcl_Filesystem *), (Tcl_Timer *), and (Tcl_Objtype *) values which
	have been const-ified. What remains is the minimum configurability
	needed to support code written for pre-8.6 headers via the new
	-DUSE_COMPAT85_CONST compiler directive.
	*** POTENTIAL INCOMPATIBILITY ***

	* generic/tclDecls.h:	make genstubs

2008-08-21  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:	Fix the cmdFrame level count in
	* generic/tclCmdIL.c:	coroutines. Fix small bug on coroutine
	* generic/tclInt.h:	rewind.

2008-08-21  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclProc.c (Tcl_DisassembleObjCmd): Added ability to
	disassemble TclOO methods. The code to do this is very ugly.

	* generic/tclOO.c (AllocObject): Suppress compilation of commands in
	the namespace allocated for each object.
	* generic/tclOOMethod.c (PushMethodCallFrame): Restore some of the
	hackery that makes calling methods of classes fast. Fixes performance
	problem introduced by the fix of [Bug 2037727].

	* generic/tclCompile.c (TclCompileScript):    Allow the suppression of
	* generic/tclInt.h (NS_SUPPRESS_COMPILATION): compilation of commands
	* generic/tclNamesp.c (Tcl_CreateNamespace):  from a namespace or its
	children.

2008-08-20  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclTest.c (TestconcatobjCmd):	Fix use of internal-only
	TclInvalidateStringRep macro. [Bug 2057479]

2008-08-17  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:	   Implementation of [coroutine] and [yield]

	* tests/unsupported.test:

	* generic/tclTest.c (TestconcatobjCmd):
	* generic/tclUtil.c (Tcl_ConcatObj):
	* tests/util.test (util-4.7):
	Fix [Bug 1447328]; the original "fix" turned Tcl_ConcatObj() into a
	hairy monster. This was exposed by [Bug 2055782]. Additionally,
	Tcl_ConcatObj could corrupt its input under certain conditions!

	*** NASTY BUG FIXED ***

2008-08-16  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: Better cmdFrame management

2008-08-14  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompile.h:			DTrace 'info' probes for tclOO
	* generic/tclDTrace.d:			method & class/object info.

	* generic/tclCompile.h:	Add support for debug logging of DTrace
	* generic/tclBasic.c:	'proc', 'cmd' and 'inst' probes (does _not_
				require a platform with DTrace).

	* generic/tclCmdIL.c (TclInfoFrame):	Check fPtr->line before
						dereferencing as line info may
						not exists when TclInfoFrame()
						is called from a DTrace probe.

	* tests/fCmd.test (fCmd-6.23):	Made result matching robust when test
					workdir and /tmp are not on same FS.

	* unix/tclUnixThrd.c:		Remove unused TclpThreadGetStackSize()

					(followup to 2008-06-12) [Bug 2016584]

	* unix/tcl.m4 (SC_PATH_X):	Check for libX11.dylib in addition to
					libX11.so et al.

2008-08-08  Don Porter	<dgp@users.sourceforge.net>S

	* generic/tclOOMethod.c (PushMethodCallFrame):	Added missing check
	for bytecode validity. [Bug 2037727]

	* generic/tclProc.c (TclProcCompileProc):	On recompile of a
	proc, clear away any entries on the CompiledLocal list from the
	previous compile. This will prevent compile of temporary variables in
	the proc body from growing the localCache arbitrarily large.

	* win/Makefile.in:
	* win/makefile.vc:

2008-08-11  Andreas Kupries  <andreask@activestate.com>

	* library/tm.tcl: Added a 'package provide' command to the generated
	ifneeded scripts of Tcl Modules, for early detection of conflicts
	between the version specified through the file name and a 'provide'
	command in the module implementation, if any. Note that this change
	also now allows Tcl Modules to not provide a 'provide' command at all,
	and declaring their version only through their filename.

	* generic/tclProc.c (Tcl_ProcObjCmd): Fixed memory leak triggered by
	* tests/proc.test: procbody::test::proc. See [Bug 2043636]. Added a
	test case demonstrating the leak before the fix. Fixed a few spelling
	errors in test descriptions as well.

	* win/makefile.bc:		use the unsigned formats in the
	* win/makefile.vc:		[binary scan] command.

2008-08-11  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* library/http/http.tcl: CRC field from zlib data should be treated as
	unsigned for 64bit support. [Bug 2046846]

2008-08-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclProc.c: Completely removed ProcCompileProc, which was a
	fix for [Bug 1482718]. This is not needed at least since varReform,
	where the local variable data at runtime is read from the CallFrame
	and/or the LocalCache.

2008-08-09  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclOO.c:	Revised TclOO's check for an interp being

	relying on documented features of command delete traces that do not in

	Proc, which can under some circumstance be out of sync with the
	localCache's. Found by dgp while investigating [Bug 2037727].

	* library/init.tcl (::unknown): Removed the [namespace inscope]
	hack that was maintained for Itcl

	*** POTENTIAL INCOMPATIBILITY *** for Itcl
	Itcl users will need a new release with Itcl's [Patch 2040295], or
	else load the tiny script in that patch by themselves (rewrite
	::unknown). Note that it is a script-only patch.

2008-08-05  Joe English	 <jenglish@users.sourceforge.net>

	* unix/tclUnixChan.c: Streamline async connect logic [Patch 1994512]

2008-08-05  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: Fix for [Bug 2038069] by dgp.
	* tests/execute.test:

2008-08-04  Miguel Sofer  <msofer@users.sf.net>

	* tests/nre.test: Added tests for [if], [while] and [for]. A test
	for [foreach] has been added and marked as knownbug, awaiting for it
	to be NR-enabled.

	* generic/tclBasic.c:	   Made atProcExit commands run

	fallback to direct evaluation of commands in a compiled script.
	[Bug 2037338]

2008-08-03  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:	   New unsupported command atProcExit that
	* generic/tclCompile.h:	   shares the implementation with tailcall.
	* generic/tclExecute.c:	   Fixed a segfault in tailcalls. Tests added.
	* generic/tclInt.h:
	* generic/tclInterp.c:
	* generic/tclNamesp.c:
	* tests/unsupported.test:

2008-08-02  Miguel Sofer  <msofer@users.sf.net>

	* tests/NRE.test (removed):	Migrated tests to standard locations,
	* tests/nre.test (new):		separating core functionality from the
	* tests/unsupported.test (new):	experimental commands.

2008-08-01  Jeff Hobbs	<jeffh@ActiveState.com>

	* doc/Exit.3:			Do not call Tcl_Finalize implicitly
	* generic/tclEvent.c:		on DLL_PROCESS_DETACH as it may lead
	* win/tclWin32Dll.c (DllMain):	to issues and the user should be
	explicitly calling Tcl_Finalize before unloading regardless. Clarify
	the docs to note the explicit need in embedded use.

2008-08-01  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Revised timing of the CmdFrame stack
	* tests/info.test:	management in TclEvalEx so that the CmdFrame
	will still be on the stack at the time Tcl_LogCommandInfo is called to
	append another level of -errorinfo information. Sets the stage to add
	file and line data to the stack trace. Added test to check that [info
	frame] functioning remains unchanged by the revision.

2008-07-31  Miguel Sofer  <msofer@users.sf.net>

	* tests/NRE.test:  Replaced all deep-recursing tests by shallower
	tests that actually measure the C-stack depth. This makes them
	bearable again (even under memdebug) and avoid crashing on failure.

	* generic/tclBasic.c:	NR-enabling [catch], [if] and [for] and
	* generic/tclCmdAH.c:	[while] (the script, not the tests)
	* generic/tclCmdIL.c:
	* generic/tclCmdMZ.c:
	* generic/tclInt.h:
	* tests/NRE.test:

	* generic/tclBasic.c:	Moved the few remaining defs from tclNRE.h to

	* generic/tclExecute.c: everywhere.
	* generic/tclInt.h:

	* generic/tclBasic.c:	 Improved tailcalls.
	* generic/tclCompile.h:
	* generic/tclExecute.c:
	* generic/tclTest.c:
	* tests/NRE.test:

	* generic/tclBasic.c (TclNREvalObjEx): New comments and code reorg
	to clarify what is happening.

	* generic/tclBasic.c: Guard against the value of iPtr->evalFlags
	changing between the times where TEOV and TEOV_exception run. Thanks
	dgp for catching this.

2008-07-29  Miguel Sofer  <msofer@users.sf.net>

	* tests/NRE.test: New tests that went MIA in the NRE revamping

	* generic/tclBasic.c:	Clean up
	* generic/tclNRE.h:
	* generic/tclExecute.c:

	* generic/tclBasic.c:	Made use of the thread's alloc cache stored in
	* generic/tclInt.h:	the ekeko at interp creation to avoid hitting
	* generic/tclNRE.h:	the TSD each time an NRE callback is pushed or
	* generic/tclThreadAlloc.c: pulled; the approach is suitably general
	to extend to every other obj allocation where an interp is know; this
	is left for some other time, requires a lot of grunt work.

	* generic/tclExecute.c:	 Fix [Bug 2030670] that cause TclStackRealloc
	to panic on rare corner cases. Thx ajpasadyn for diagnose and patch.

	* generic/tcl.decls:	 Completely revamped NRE implementation, with
	* generic/tclBasic.c:	 (almost) unchanged API.
	* generic/tclCompile.h:
	* generic/tclExecute.c:	 TEBC will require a bit of a facelift, but
	* generic/tclInt.decls:	 TEOV at least looks great now. There are new
	* generic/tclInt.h:	 tests (incomplete!) to verify that execution
	* generic/tclInterp.c:	 is indeed in the same TEBC instance, at the
	* generic/tclNRE.h:	 same level in all stacks involved. Tailcalls
	* generic/tclNamesp.c:	 are still a bit leaky, still deserving to be
	* generic/tclOOBasic.c:	 in tcl::unsupported.
	* generic/tclOOMethod.c:
	* generic/tclProc.c:	 Uninit'd var warnings in TEBC with -O2, no
	* generic/tclTest.c:	 warnings otherwise.

2008-07-28  Jan Nijtmans  <nijtmans@users.sf.net>

	* doc/FileSystem.3:		CONSTified many functions using
	* generic/tcl.decls:		Tcl_FileSystem which all are supposed
	* generic/tclDecls.h:		to be a constant, but this was not
	* generic/tclFileSystem.h:	reflected in the API: Tcl_FSData,
	* generic/tclIOUtil.c:		Tcl_FSGetInternalRep, Tcl_FSRegister,
	* generic/tclPathObj.c:		Tcl_FSNewNativePath, Tcl_FSUnregister,
	* generic/tclTest.c:		Tcl_FSGetFileSystemForPath ...
	This change complies with TIP #27.
	***POTENTIAL INCOMPATIBILITY***

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.

2008-07-27  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOOMethod.c (PushMethodCallFrame): Remove hack that should
	have gone when this code was merged into Tcl.

2008-07-27  Jan Nijtmans  <nijtmans@users.sf.net>

	* doc/Object.3:		CONSTified 3 functions using Tcl_ObjType
	* doc/ObjectType.3:	which all are supposed to be a constant, but
	* generic/tcl.decls:	this was not reflected in the API:
	* generic/tcl.h:	Tcl_RegisterObjType, Tcl_ConvertToType,
	* generic/tclDecls.h:	Tcl_GetObjType
	* generic/tclObj.c:	Introduced a CONST86_RETURN, so extensions
	* generic/tclCompCmds.c: which use Tcl_ObjType directly can be
	* generic/tclOOMethod.c: modified to compile against both Tcl 8.5 and
	* generic/tclTestobj.c:	Tcl 8.6. tclDecls.h regenerated
	This change complies with TIP #27.
	***POTENTIAL INCOMPATIBILITY***

2008-07-25  Andreas Kupries  <andreask@activestate.com>

	* test/info.test: More work on singleTestInterp usability. [1605269]

	* tests/info.test: Tests 38.* added, exactly testing the tracking of
	location for uplevel scripts. Resolved merge conflict on info-37.0,
	switched !singleTestInterp constraint to glob matching instead. Ditto
	info-22.8, removed constraint, more glob matching, and reduced the
	depth of the stack we check. More is coming, right now I want to
	commit the bug fixes.

	* tests/oo.test: Updated oo-22.1 for expanded location tracking.

	* 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): Added missing cleanup of extended
	location information.

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]

2008-07-24  Jan Nijtmans  <nijtmans@users.sf.net>

	* doc/Notifier.3:      CONSTified 4 functions in the Notifier which
	* doc/Thread.3:	       all have a Tcl_Time* in it which is supposed
	* generic/tcl.decls:   to be a constant, but this was not reflected
	* generic/tcl.h:       reflected in the API:
	* generic/tclDecls.h:	    Tcl_SetTimer, Tcl_WaitForEvent,
	* generic/tclNotify.c:	    Tcl_ConditionWait, Tcl_SetMaxBlockTime
	* macosx/tclMacOSXNotify.c:
	* generic/tclThread.c: Introduced a CONST86, so extensions which have
	* unix/tclUnixNotfy.c: have their own Notifier (are there any?) can
	* unix/tclUnixThrd.c:  can be modified to compile against both Tcl
	* win/tclWinNotify.c:  Tcl 8.5 and Tcl 8.6
	* win/tclWinThrd.c:    Regenerated tclDecls.h with "make stubs".
	This change complies with TIP #27
	***POTENTIAL INCOMPATIBILITY***

2008-07-23  Alexandre Ferrieux	<ferrieux@users.sourceforge.net>

	* tests/lrange.test: Added relative speed test to check for lrange
	in-place optimization committed 2008-06-30.
	* tests/binary.test: Added relative speed test to check for pure byte
	array CONCAT1 optimization committed 2008-06-30.

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 of
	* generic/tclCompile.c: eoFramePtr, doesn't need the line information,
	* 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
	special case this based on the frame type (i.e.
	TCL_LOCATION_EVAL_LIST). Added a testcase demonstrating the new
	behaviour.

2008-07-23  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c (GetCommandSource): Added comment with
	explanation and warning for waintainers.

2008-07-22  Andreas Kupries  <andreask@activestate.com>

	* generic/tclCompile.c: Made the new TclEnterCmdWordIndex static, and
	* generic/tclCompile.h: ansified.

	* generic/tclBasic.c: Ansified the new functions. Added missing
	function comments.

	* generic/tclBasic.c: Reworked the handling of bytecode literals for
	* generic/tclCompile.c: #280 to fix the abysmal performance for deep
	* generic/tclCompile.h: recursion, replaced the linear search through
	* generic/tclExecute.c: the whole stack with another hashtable and
	* generic/tclInt.h: simplified the data structure used by the compiler
	by using an array instead of a hashtable. Incidentially this also
	fixes the memory leak reported via [Bug 2024937].

2008-07-22  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:	 Added numLevels field to CommandFrame, let
	* generic/tclExecute.c:	 GetCommandSource use it. This solves [Bug
	* generic/tclInt.h:	 2017146]. Thx dgp for the analysis.

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 absolute
	* generic/tclCompCmds.c: location of literal procedure arguments, and
	* generic/tclCompile.c: making this information available to uplevel
	* generic/tclCompile.h: eval, and siblings. This allows proper
	* generic/tclInterp.c: tracking of absolute location through custom
	* generic/tclInt.h: (Tcl-coded) control structures based on uplevel,
	* generic/tclNamesp.c: etc.
	* generic/tclProc.c:

2008-07-21  Miguel Sofer  <msofer@users.sf.net>

	* generic/tcl.decls:	  Changed the implementation of
	* generic/tclBasic.c:	  [namespace import]; removed
	* generic/tclDecls.h:	  Tcl_NRObjProc, replaced with
	* generic/tclExecute.c:	  Tcl_NRCmdSwap (proposed public
	* generic/tclInt.h:	  NRE API). This should fix
	* generic/tclNRE.h:	  [Bug 582506].
	* generic/tclNamesp.c:
	* generic/tclStubInit.c:

	* generic/tclBasic.c:	 NRE: enabled calling NR commands
	* generic/tclExecute.c:	 from the callbacks. Completely
	* generic/tclInt.h:	 redone tailcall implementation

2008-07-20  Kevin B. Kenny  <kenykb@acm.org>

	* tests/fileName.test: Repaired the failing test fileName-15.7 from
	dkf's commit earlier today.

2008-07-20  Donal K. Fellows  <dkf@users.sf.net>

	* 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.

	* tests/fileName.test: Revise to reduce the obscurity of tests. In
	particular, all tests should now produce informative messages on
	failure and the quantity of [catch]-based obscurity is now greatly
	reduced; non-erroring is now checked for directly.

2008-07-19  Donal K. Fellows  <dkf@users.sf.net>

	* tests/env.test: Add LANG to the list of variables that are not
	touched by the environment variable tests, so that subprocesses can
	get their system encoding correct.

	* tests/exec.test, tests/env.test: Rewrite so that non-ASCII
	characters are not used in the final comparison. Part of fixing [Bug
	1513659].

2008-07-18  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:	 Optimization: replace calls to

	NRE-enablement of the class construction methods.

2008-07-18  Miguel Sofer  <msofer@users.sf.net>

	* tests/NRE.test:  Added basic tests for deep TclOO calls

2008-07-18  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclDictObj.c (DictWithCmd, DictUpdateCmd): Fix refcounting
	bugs that caused crashes [Bug 2017857].

	* generic/tclBasic.c (TclNREvalObjEx): Streamline the management of
	the command frame (opt).

2008-07-17  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclDictObj.c (DictWithCmd, FinalizeDictWith): Split the
	implementation of [dict with] so that it works with NRE.

	* generic/tclOO.c, generic/tclOOInt.h, generic/tclOOBasic.c:
	* generic/tclOOCall.c, generic/tclOOMethod.c: NRE-enable the TclOO
	implementation in Tcl. No change to public APIs, except that method
	implementations can now be NRE-aware if they choose (which normal
	methods and forwards are). On the other hand, callers of
	TclOOInvokeObject (which is only in the internal stub table) will need
	to deal with the fact that it's only safe to call inside an NRE-aware

2008-07-08  Donal K. Fellows  <dkf@users.sf.net>

	* doc/CrtInterp.3: Tighten up the descriptions of behaviour to make
	this page easier to read for a "Tcl 8.6" audience.

2008-07-07  Andreas Kupries  <andreask@activestate.com>

	* generic/tclCmdIL.c (InfoFrameCmd): Fixed unsafe idiom of setting
	the interp result found by Don Porter.

2008-07-07  Donal K. Fellows  <dkf@users.sf.net>

	* doc/regexp.n, doc/regsub.n: Correct examples. [Bug 1982642]

2008-07-06  Donal K. Fellows  <dkf@users.sf.net>

	* doc/lindex.n: Improve examples.

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 report 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]

2008-07-01  Donal K. Fellows  <dkf@users.sf.net>

	* generic/regc_nfa.c (duptraverse): Impose a maximum stack depth on
	the single most recursive part of the RE engine. The actual maximum
	may need tuning, but that needs a system with a small stack to carry
	out. [Bug 1905562]

	* tests/string.test: Eliminate non-ASCII characters from the actual
	test script. [Bug 2006884]

2008-06-30  Donal K. Fellows  <dkf@users.sf.net>

	* doc/ObjectType.3: Clean up typedef formatting.

2008-06-30  Don Porter	<dgp@users.sourceforge.net>

	* doc/ObjectType.3:	Updated documentation of the Tcl_ObjType
	struct to match expectations of Tcl 8.5. [Bug 1917650]

2008-06-30  Alexandre Ferrieux	<ferrieux@users.sourceforge.net>

	* generic/tclCmdIL.c: Lrange cleanup and in-place optimization. [Patch
	1890831]

	* generic/tclExecute.c: Avoid useless String conversion for CONCAT1 of
	pure byte arrays. [Patch 1953758]

2008-06-29  Donal K. Fellows  <dkf@users.sf.net>

	* doc/*.1, doc/*.3, doc/*.n: Many small updates, purging out of date
	change bars and cleaning up the formatting of typedefs. Added a few
	missing bits of documentation in the process.

2008-06-29  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclPathObj.c:	 Plug memory leak in [Bug 1999176] fix. Thanks
	to Rolf Ade for detecting.

2008-06-29  Donal K. Fellows  <dkf@users.sf.net>

	* doc/interp.n: Corrected order of subcommands. [Bug 2004256]
	Removed obsolete (i.e. 8.5) .VS/.VE pairs.

	* doc/object.n (EXAMPLES): Fix incorrect usage of oo::define to be
	done with oo::objdefine instead. [Bug 2004480]

2008-06-28  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclPathObj.c:	 Plug memory leak in [Bug 1972879] fix. Thanks
	to Rolf Ade for detecting and Dan Steffen for the fix. [Bug 2004654]

2008-06-26  Andreas Kupries  <andreask@activestate.com>

	* unix/Makefile.in: Followup to my change of 2008-06-25, make code
	generated by the Makefile and put into the installed tm.tcl
	conditional on interpreter safeness as well. Thanks to Daniel Steffen
	for reminding me of that code.

2008-06-25  Don Porter	<dgp@users.sourceforge.net>

	*** 8.6a1 TAGGED FOR RELEASE ***

	* changes:	Updates for 8.6a1 release.

	* generic/tclOO.h:	Bump to TclOO 0.5.

2008-06-25  Andreas Kupries  <andreask@activestate.com>

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]

2008-06-24  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* doc/fileevent.n: Fix examples and comment on eof use. [Bug 1995063]

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]

2008-06-20  Don Porter	<dgp@users.sourceforge.net>

	* changes:	Updates for 8.6a1 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/tclOO.c (Tcl_ObjectContextInvokeNext): Corrected 'next' (at
	* tests/oo.test (oo-7.8):	end of a call chain) to make it
	* doc/next.n:			consistent with the TIP. [Bug 1998244]

	* generic/tclOOCall.c (AddSimpleClassChainToCallContext): Make sure
	* tests/oo.test (oo-14.8): that class mixins are processed in the
	documented order. [Bug 1998221]

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

	* 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. [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): Moved the code looking up the
	* tests/info.test: 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. [Bug 1987851]

2008-06-16  Andreas Kupries  <andreask@activestate.com>

	* tests/ioTrans.test (iortrans-11.*): Fixed same issue as for
	iortrans.tf-11.*, cleanup of temp file, making this a followup to the
	entry on 2008-06-10 by myself.

2008-06-13  David Gravereaux <davygrvy@pobox.com>

	* win/rules.vc: SYMBOLS macro is now being set to zero when $(OPTS) is
	not available.
	* win/makefile.vc: The Stubs source files (tclStubLib.c and
	tclOOStubLib.c) should not be compiled with the -GL flag.

2008-06-13  Joe Mistachkin  <joe@mistachkin.com>

	TIP #285 IMPLEMENTATION

	* doc/Eval.3: Added documentation for the Tcl_CancelEval and
	Tcl_Canceled functions and the TCL_CANCEL_UNWIND flag bit.
	* doc/after.n: Corrected the spelling of 'canceled' in the
	documentation.
	* doc/interp.n: Added documentation for [interp cancel].
	* generic/tcl.decls: Added the Tcl_CancelEval and Tcl_Canceled
	functions to the stubs table.
	* generic/tcl.h: Added the TCL_CANCEL_UNWIND flag bit.
	* generic/tclBasic.c: The bulk of the script cancellation
	functionality is defined here. Added code to initialize and manage the
	script cancellation hash table in a thread-safe manner. Reset script
	cancellation flags prior to increasing the nesting level (if the
	nesting level is currently zero) and always cooperatively check for
	script cancellation near the start of TclEvalObjvInternal and after
	invoking async handlers.
	* generic/tclDecls.h: Regenerated.
	* generic/tclEvent.c: Call TclFinalizeEvaluation during finalization
	to cleanup the script cancellation hash table. During [vwait], always
	cooperatively check for script cancellation. Corrected the spelling of
	'canceled' in comments to be consistent with the documentation.
	* generic/tclExecute.c: Reset script cancellation flags prior to
	increasing the nesting level (if the nesting level is currently zero)
	and always cooperatively check for script cancellation after invoking
	async handlers. Prevent [catch] from catching script cancellation when
	the TCL_CANCEL_UNWIND flag is set (similar to the manner used by TIP
	143 when a limit has been exceeded).
	* generic/tclInt.decls: Added TclResetCancellation to the internal
	stubs table.
	* generic/tclInt.h: Added asyncCancel and asyncCancelMsg fields to the
	private Interp structure. Added private interp flag value CANCELED to
	help control script cancellation.
	* generic/tclIntDecls.h: Regenerated.
	* generic/tclInterp.c (Tcl_InterpObjCmd): Added [interp cancel]
	subcommand.
	* generic/tclNotify.c (Tcl_DeleteEventSource): Corrected the spelling
	of 'canceled' in comments to be consistent with the documentation.
	* generic/tclParse.c: Reset script cancellation flags prior to
	* generic/tclProc.c: increasing the nesting level (if the nesting
	level is currently zero) and cooperatively check for script
	cancellation prior to evaluating commands.
	* generic/tclStubInit.c: Regenerated.
	* generic/tclThreadTest.c (Tcl_ThreadObjCmd): Added script
	cancellation support ([testthread cancel]).
	Modified [testthread id] to allow querying of the 'main' thread ID.
	Corrected comments to reflect the actual command syntax. Made
	[testthread wait] cooperatively check for script cancellation. Added
	[testthread event] to allow for processing one pending event without
	blocking.
	* generic/tclTimer.c: Delay for a maximum of 500 milliseconds prior to
	checking for async handlers and script cancellation.
	* tests/cmdAH.test: Changed [interp c] to [interp create].
	* tests/interp.test: Added and fixed tests for [interp cancel].
	* tests/thread.test: Added tests for script cancellation via
	[testthread cancel].
	* tools/man2help2.tcl: Fixed problems with WinHelp target (see
	* tools/man2tcl.c: [Bug 1934200], [Bug 1934265], and [Bug 1934272]).
	* win/makefile.vc: Added 'pdbs' option for Windows build rules to
	* win/rules.vc:	   allow for non-debug builds with full symbols.
	* win/tcl.hpj.in: Corrected version for WinHelp target.
	* win/tclWinNotify.c: Used SleepEx and WaitForSingleObjectEx on
	* win/tclWinThrd.c: Windows because they are alertable.

2008-06-12  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in:		Add complete deps on tclDTrace.h.

	* generic/tclOO.c:		Use TclOOStubs hooks field to retrieve
	* generic/tclOODecls.h:		TclOOIntStubs pointer. [Bug 1980953]
	* generic/tclOOIntDecls.h:
	* generic/tclOOStubInit.c:
	* generic/tclOOStubLib.c:

	* generic/tclIORTrans.c:	Fix signed <-> unsigned cast warnings.

	* 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 tclIORTrans.c; updates and
						cleanup for Xcode 3.1/Leopard.
	* macosx/Tcl.xcode/project.pbxproj:	Sync Tcl.xcodeproj changes.
	* macosx/README:			Document new build configs.

2008-06-10  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.

2008-06-10  Andreas Kupries  <andreask@activestate.com>

	* tests/ioTrans.test (iortrans.tf-6.1): Fixed the [Bug 1988552],
	reported by Kevin. Have to close the channel before removal of the
	file. Fixed same bug in test 'iortrans.tf-11.0', after fixing missing
	cleanup of the file in 'iortrans.tf-11.*'. Lastly fixed the names of
	the threaded tests 'iortrans-8.*' to the correct 'iortrans.tf-8.*'.

2008-06-09  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* generic/tclIORTrans.c (ReflectInput): Fixed a bug triggered by Pat
	Thoyts <patthoyts@users.sourceforge.net>. Reset the EOF flag after
	draining the Tcl level into the result buffer, to make sure that the
	result buffer will be drained as well by repeated calls to
	ReflectInput should it contain more than one buffer-full of data.
	Without that reset the higher I/O system will not call on ReflectInput
	anymore due to the assumed EOF, thus losing the data which did not fit
	in the buffer of the call which caused the eof and drain.

2008-06-09  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOOCall.c (TclOOGetSortedMethodList): Plug memory leak
	that occurred when all methods were hidden. [Bug 1987817]

2008-06-08  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:	   Compilation of uplevel scripts, allow
	* generic/tclCompCmds.c:   non-body compiled scripts to access the
	* generic/tclCompile.c:	   LVT (but not to extend it) and enable the
	* generic/tclCompile.h:	   canonical list opt to sidestep the
	* generic/tclExecute.c:	   compiler. [Patch 1973096]
	* generic/tclProc.c:
	* tests/uplevel.test:

2008-06-06  Andreas Kupries  <andreask@activestate.com>

	TIP #230 IMPLEMENTATION

	* generic/tclIOCmd.c: Integration of transform commands into 'chan'
			      ensemble.
	* generic/tclInt.h: Definitions of the transform commands.
	* generic/tclIORTrans.c: Implementation of the reflection transforms.
	* tests/chan.test:  Tests updated for new sub-commands of 'chan'.
	* tests/ioCmd.test: Tests updated for new sub-commands of 'chan'.
	* tests/ioTrans.test: Whole new set of tests for the reflection
			      transform.
	* unix/Makefile.in: Integration of new files into build rules.
	* win/Makefile.in:  Integration of new files into build rules.
	* win/makefile.vc:  Integration of new files into build rules.

	NOTE: The file 'tclIORTrans.c' has a lot of code in common with the
	      file 'tclIORChan.c', as that made it much easier to develop the
	      reference implementation as a separate module. Now that the
	      transforms have been committed the one thing left to do is to go
	      over both modules and see which of the common parts we can
	      factor out and share.

2008-06-04  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* generic/tclBinary.c: TIP #317 implementation
	* tests/binary.test:

2008-06-02  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclOO.c (ReleaseClassContents): Fix the one remaining
	valgrind complaint about oo.test, caused by failing to protect the
	Object as well as the Class corresponding to a subclass being deleted
	and hence getting a freed-memory read when attempting to delete the
	class command. [Bug 1981001]

2008-06-01  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOOMethod.c (Tcl_NewMethod): Complete the fix of [Bug
	1981001], previous fix was incomplete though helpful in telling me
	where to look.

2008-06-01  Joe Mistachkin  <joe@mistachkin.com>

	* win/Makefile.in: Add tclOO genstubs to Windows makefiles and remove
	* win/makefile.vc: -DBUILD_tcloo because it is no longer required.

2008-06-01  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclOODecls.h:	   Added the swizzling of DLLEXPORT and
	* generic/tclOOIntDecls.h: DLLIMPORT needed to make EXTERN work.

	* generic/tclDictObj.c:	 Added missing initializers to the ensemble
				 map to silence a compiler warning. Thanks to
				 George Peter Staplin for the report.

	* generic/tclOOMethod.c: Fix a bug where the refcount of a method was
				 reset if the method was redefined while there
				 was an active invocation. [Bug 1981001]

2008-06-01  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclOO.decls, unix/Makefile.in (genstubs): Make generation of
	stub tables correct.
	* generic/tclOO{Decls.h,IntDecls.h,StubInit.c,StubLib.c}: Fixes to
	make the generation work correctly, removing subtle differences
	between output of different versions of stub generator.

2008-06-01  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclOOStubLib.c:	Ensure use of tcl stubs; include in
	* unix/Makefile.in:		stub lib; disable broken tclOO
					genstubs

	* generic/tclOO.c:		Make tclOO stubs tables 'static const'
	* generic/tclOODecls.h:		and stub table pointers MODULE_SCOPE
	* generic/tclOOIntDecls.h:	(change generated files manually
	* generic/tclOOStubInit.c:	pending genstubs support for tclOO).
	* generic/tclOOStubLib.c:

	* generic/tclOO.c:		Fix warnings for 'int<->ptr
	* generic/tclOOCall.c:		conversion' and 'signed vs unsigned
	* generic/tclOOMethod.c:	comparison'.

	* tests/msgcat.test:	Fix for ::tcl::mac::locale with @modifier.

	* tools/tsdPerf.tcl:	Use [info sharedlibextension]

	TIP#257 IMPLEMENTATION

	* generic/tclBasic.c, generic/tclOOInt.h: Correct declarations.
	* win/Makefile.in, win/makefile.bc, win/makefile.vc: Build support for
	Win32, from Joe Mistachkin. [Patch 1980861]

	* generic/tclOO*, doc/*, tests/oo.test: Port of implementation of
	TclOO to sit directly inside Tcl. Note that this is incomplete (e.g.
	no build support yet for Windows).

2008-05-26  Jeff Hobbs	<jeffh@ActiveState.com>

	* tests/io.test (io-53.9): Need to close chan before removing file.

2008-05-26  Donal K. Fellows  <dkf@users.sf.net>

	* win/makefile.bc:		    Remove deprecated winhelp target.
	* win/Makefile.in, win/makefile.vc: It didn't work correctly anyway.

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]

2008-05-20  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]

2008-05-15  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* win/makefile.vc: We should use the thread allocator for threaded
	* win/rules.vc:	   builds. Added 'tclalloc' option to disable.

2008-05-09  George Peter Staplin  <georgeps@xmission.com>

	* tools/tsdPerf.c:	A loadable Tcl extension for testing TSD
	performance.
	* tools/tsdPerf.tcl:	A simplistic tool that uses the thread
	extension and tsdPerf.so to get some performance metrics by,
	simulating, simple TSD contention.

2008-05-09  George Peter Staplin  <georgeps@xmission.com>

	* generic/tcl.h:	Make Tcl_ThreadDataKey a void *.
	* generic/tclInt.h:	Change around some function names and add some
	new per-platform declarations for thread-specific data functions.
	* generic/tclThread.c:	Make use of of the new function names that no
	longer have a Tclp prefix.
	* generic/tclThreadStorage.c: Replace the core thread-specific data
	(TSD) mechanism with an array offset solution that eliminates the hash
	tables, and only uses one slot of native TSD. Many thanks to Kevin B.
	Kenny for his help with this.

	* unix/tclUnixThrd.c:	Add platform-specific TSD functions for use by
	* win/tclWinThrd.c:	tclThreadStorage.c.

2008-05-09  Kevin B. Kenny  <kennykb@acm.org>

	* tests/dict.test (dict-19.2): Corrected a bug where the test was
	changed to use [apply] instead of a temporary proc, but the cleanup
	script still attempted to delete the temporary proc.

2008-05-07  Donal K. Fellows  <dkf@cspool38.cs.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.

2008-05-02  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* generic/tclBasic.c:	 Converted the [binary] command into an
	* generic/tclBinary.c:	 ensemble.
	* generic/tclInt.h:
	* test/binary.test:	 Updated the error tests for ensemble errors.

	* generic/tclFileName.c: Reverted accidental commit of TIP 316 APIs.

2008-04-27  Donal K. Fellows  <dkf@users.sf.net>

	* */*.c: A large tranche of getting rid of pre-C89-isms; if your
	compiler doesn't support things like proper function declarations,
	'void' and 'const', borrow a proper one when building Tcl. (The header
	files allow building things that link against Tcl with really ancient
	compilers still; the requirement is just when building Tcl itself.)

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.

2008-04-21  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclIOUtil.c:		Removed all code delimited by
	* generic/tclTest.c:		USE_OBSOLETE_FS_HOOKS, completing
	* tests/ioCmd.test:		the deprecation path for these
	* tests/ioUtil.test (removed):	obsolete interfaces. (Code was active
	in Tcl 8.4, present but enabled only by customized compile switch in
	Tcl 8.5, and now completely gone for Tcl 8.6). Also removed all tests
	relevant only to the removed interfaces.

2008-04-19  George Peter Staplin <georgeps@xmission.com>

	* doc/Ensemble.3: Fix a typo: s/defiend/defined/
	Thanks to hat0 for spotting this.

2008-04-16  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclInt.h:		Make stubs tables 'static const' and
	* generic/tclStubInit.c:	export only module-scope pointers to
	* generic/tclStubLib.c:		the main stubs tables (for package
	* tools/genStubs.tcl:		initialization). [Patch 1938497]
	* generic/tclBasic.c (Tcl_CreateInterp):
	* generic/tclTomMathInterface.c (TclTommath_Init):

	* generic/tclInt.h:		Revise Tcl_SetNotifier() to use a
	* generic/tclNotify.c:		module-scope hooks table instead of
	* generic/tclStubInit.c:	runtime stubs-table modification;
	* macosx/tclMacOSXNotify.c:	ensure all hookable notifier functions
	* win/tclWinNotify.c:		check for hooks; remove hook checks in
	* unix/tclUnixNotfy.c:		notifier API callers. [Patch 1938497]

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.

2008-04-15  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in:	Adjust tclDTrace.h dependencies for removal
				of tclStubLib.o from TCL_OBJS. [Bug 1942795]

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.

2008-04-10  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  Donal K. Fellows  <dkf@users.sf.net>

	* tests/{fCmd,unixFCmd,winFCmd,winFile}.test: Tidying up of the test
	suite to make better use of tcltest2 and be clearer about what is
	being tested.

	* win/Makefile.in (html): Added target for doing convenient
	documentation builds, mirroring the one from unix/Makefile.

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. Test case is not affected by the value of -size,
	test flag restoration and that evrything was properly copied.

	* 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]

2008-04-09  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

2008-04-08  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: Added comments to the alignment macros used in
	GrowEvaluationStack() and friends.

2008-04-08  Daniel Steffen  <das@users.sourceforge.net>

	* tools/genStubs.tcl:	Revert erroneous 2008-04-02 change marking
				*StubsPtr as EXTERN instead of extern.

	* generic/tclDecls.h:	make genstubs
	* generic/tclIntDecls.h:
	* generic/tclIntPlatDecls.h:
	* generic/tclPlatDecls.h:
	* generic/tclTomMathDecls.h:

2008-04-07  Andreas Kupries  <andreask@activestate.com>

	* tests/io.test (io-53.10): Testcase for bi-directional fcopy.
	* tests/chanio.test:
	* generic/tclIO.c: Additional changes to data structures for fcopy and
	* generic/tclIO.h: channels to perform proper cleanup in case of a
	channel having two background copy operations running as is now
	possible.

	* generic/tclIO.c (BUSY_STATE, CheckChannelErrors, TclCopyChannel):
	New macro, and the places using it. This change allows for
	bi-directional fcopy on channels. Thanks to Alexandre Ferrieux
	<ferrieux@users.sourceforge.net> for the patch. [Bug 1350564]

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>

	* 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.
	* 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).

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  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tcl.decls:	Remove 'export' declarations of symbols now
				only in libtclstub and no longer in libtcl.

	* generic/tclStubLib.c:	Make symbols in libtclstub.a MODULE_SCOPE to
	* tools/genStubs.tcl:	avoid exporting them from libraries that link
				with -ltclstub; constify tcl*StubsPtr and stub
				table hook pointers. [Bug 1819422]

	* generic/tclDecls.h:	make genstubs
	* generic/tclIntDecls.h:
	* generic/tclIntPlatDecls.h:
	* generic/tclPlatDecls.h:
	* generic/tclStubInit.c:
	* generic/tclTomMathDecls.h:

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
			       Michael Schlenker.

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

	* generic/tclStubLib.c:	Removed needless #ifdef complexity.

	* generic/tclStubLib.c (Tcl_InitStubs):	Added missing error message.
	* generic/tclPkg.c (Tcl_PkgInitStubsCheck):

	* tools/genStubs.tcl:	creation so that "tclStubsPtr" is not present
	* unix/Makefile.in:	in libtcl.so, but is present only in
	* win/Makefile.in:	libtclstub.a. This tightens up the rules for

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>

	*** 8.5.2 TAGGED FOR RELEASE ***

	* changes:		Updated for 8.5.2 release.

2008-03-28  Donal K. Fellows  <dkf@users.sf.net>

	* tests/fCmd.test: Substantial rewrite to use many more tcltest
	features. Great reduction in quantity of [catch] gymnastics. Several
	buggy tests fixed, including one where the result of the previous test
	was being checked!

2008-03-27  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4 (SunOS-5.1x): Fix 64bit support for Sun cc. [Bug
	1921166]

	* unix/configure: autoconf-2.59

2008-03-26  Don Porter	<dgp@users.sourceforge.net>

	* changes:		Updated for 8.5.2 release.

2008-03-24  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* generic/tclBinary.c: [Bug 1923966] - crash in binary format
	* tests/binary.test:   Added tests for the above crash condition.

2008-03-21  Donal K. Fellows  <dkf@users.sf.net>

	* doc/switch.n: Clarified documentation in respect of two-argument
	invokation. [Bug 1899962]

	* tests/switch.test: Added more tests of regexp-mode compilation of
	the [switch] command. [Bug 1854435]

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>

	* generic/tclExecute.c:	Patch from Miguel Sofer to correct the
	alignment of memory allocated by GrowEvaluationStack(). [Bug 1914503]

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
	alignment right. Workaround for [Bug 1914503].

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

	* generic/tclTest.c:  Ignore the return value of write() when we are
	* unix/tclUnixPipe.c: about to exit anyways.

2008-03-13  Daniel Steffen  <das@users.sourceforge.net>

	* unix/configure.in: Use backslash-quoting instead of double-quoting
	* unix/tcl.m4:	     for lib paths in tclConfig.sh. [Bug 1913622]
	* unix/configure:    autoconf-2.59

2008-03-13  Don Porter	<dgp@users.sourceforge.net>

	* changes:		Updated for 8.5.2 release.

	Moore. [Patch 1800636]

2008-03-12  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.xcodeproj/project.pbxproj:	Add support for Xcode 3.1

	* library/http/pkgIndex.tcl:		interface. [Bug 559898]
	* doc/http.n, tests/http.test:		Added -keepalive and
	-protocol 1.1 with chunked transfer encoding support. [Bug 1063703,
	1470377, 219225] (default keepalive is 0)
	Added ability to override Host in -headers. [Bug 928154]
	Added -strict option to control URL validation on per-call basis.
	[Bug 1560506]

2008-03-11  Jeff Hobbs	<jeffh@ActiveState.com>

	to be re-sourced without overwriting http state.

2008-03-11  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclEncoding.c (LoadEscapeEncoding): Avoid leaking escape
	sub-encodings, fixes encoding-11.1 failing after iso2022-jp loaded.
	[Bug 1893053]

	* macosx/tclMacOSXNotify.c: Avoid using CoreFoundation after fork() on
	Darwin 9 even when TclpCreateProcess() uses vfork().

	* macosx/Tcl.xcodeproj/project.pbxproj:	Add support for Xcode 3.1 and
	* macosx/Tcl.xcodeproj/default.pbxuser:	configs for building with
	* macosx/Tcl-Common.xcconfig:		gcc-4.2 and llvm-gcc-4.2.

	* unix/tclUnixPort.h:			Workaround vfork() problems in

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].

	* 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

	* 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.

	* 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

	* 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
