2008-05-31  Donal K. Fellows  <dkf@users.sf.net>

	TIP#257 IMPLEMENTATION

	* 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
	tclThreadStorage.c.
	* win/tclWinThrd.c: 	Add platform-specific TSD functions for use by
	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. [Bug 1557855]. Basic patch by
	Alexandre Ferrieux <ferrieux@users.sourceforge.net>, with
	modifications from me to separate overflow from true negative value.
	Extended testsuite.

2008-04-09  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. [Bug 1350564]. Thanks to Alexandre
	Ferrieux <ferrieux@users.sourceforge.net> for the patch.

2008-04-07  Reinhard Max  <max@suse.de>

	* generic/tclStringObj.c (Tcl_AppendFormatToObj): Fix [format {% d}]
	so that it behaves the same way as in 8.4 and as C's printf().
	* tests/format.test: Add a test for '% d' and '%+d'.

2008-04-05  Kevin B. Kenny  <kennykb@acm.org>

	* 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):

	* README:		Bump version number to 8.6a0

	* generic/tclBasic.c:	Revised stubs-generation tool and interp
	* 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
	* win/makefile.bc:	users of the stubs interfaces. [Bug 1819422]

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 ***

	* generic/tcl.h:	Bump to 8.5.2 for release.

	* tools/tcl.wse.in:
	* unix/configure.in:
	* unix/tcl.spec:

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!

2008-03-20  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. See [Bug 1914604]. Solution slightly different
	than proposed in the report. Using the underscored form TCLX_y_TM_PATH
	even if TCLX.y_TM_PATH exists. Also using a loop to cut prevent code
	replication.

2008-03-16  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCompCmds.c (TclCompileDictForCmd): Correct the handling
	of stack space calculation (the jump pattern used was confusing the
	simple-minded code doing the calculations). [Bug 1903325]

	* doc/lreplace.n: Clarified documentation of what happens with
	negative indices. [Bug 1905809] Added example, tidied up formatting.

2008-03-14  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c (OldMathFuncProc):	Same workaround protection
	from bad TclStackAlloc() alignment. Thanks George Peter Staplin.

	* generic/tclCmdIL.c (Tcl_LsortObjCmd):	Use ckalloc() to allocate
	SortElement arrays instead of TclStackAlloc() which isn't getting
	alignment right. Workaround for [Bug 1914503].

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

	* 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.

2008-03-12  Andreas Kupries <andreask@activestate.com>

	* doc/info.n: Replaced {expand} with {*}.

2008-03-12  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/Makefile.in (install-libraries):	Bump http to 2.7
	* win/Makefile.in (install-libraries):	Added -myaddr option to allow
	* library/http/http.tcl (http::geturl):	control of selected socket
	* 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>

	* doc/http.n:				[Bug 1599901, 862554]

	* library/http/http.tcl: Whitespace changes, code cleanup. Allow http
	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:	targets for building with
	* macosx/Tcl-Common.xcconfig:		gcc-4.2 and llvm-gcc-4.2.

	* unix/tclUnixPort.h:			Workaround vfork() problems
						in llvm-gcc-4.2.1 -O4 build.

	* unix/tclUnixPort.h:			Move MODULE_SCOPE compat define
						to top [Bug 1911102].

	* macosx/GNUmakefile:			Fix quoting to allow paths to
	* macosx/Tcl-Common.xcconfig:		${builddir} and ${INSTALL_ROOT}
	* unix/Makefile.in:			to contain spaces.
	* unix/configure.in:
	* unix/install-sh:
	* unix/tcl.m4:
	* tests/ioCmd.test:

	* unix/configure:			autoconf-2.59

	* unix/Makefile.in (install-strip):	Strip non-global symbols from
						dynamic library.

	* unix/tclUnixNotfy.c:			Fix warning.

	* tests/exec.test (exec-9.7):		Reduce timing sensitivity
	* tests/socket.test (socket-2.11):	(esp. on multi-proc machines).

	* tests/fCmd.test (fCmd-9.4):		Skip on Darwin 9 (xfail).

2008-03-11  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (TclDeleteNamespaceVars):
	* tests/var.test (var-8.2): Unset traces on vars should be called with
	a FQ named during namespace deletion. This was causing infinite loops
	when unset traces recreated the var, as reported by Julian Noble. [Bug
	1911919]

2008-03-10  Don Porter	<dgp@users.sourceforge.net>

	* changes:		Updated for 8.5.2 release.

	* doc/http.n:	Revised to indicate that [package require http 2.5.5]
	is needed to get all the documented commands ([http::meta]).

	* generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd):  Added error
	* tests/event.test (event-5.*):	checking to protect against callers
	passing invalid return options dictionaries. [Bug 1901113]

	* generic/tclBasic.c (ExprAbsFunc):	Revised so that the abs()
	* tests/expr.test:	function and the [::tcl::mathfunc::abs]
	command do not return the value of -0, or equivalent values with more
	alarming string reps like -1e-350. [Bug 1893815]

2008-03-07  Andreas Kupries  <andreask@activestate.com>

	* generic/tclResult.c (ReleaseKeys): Workaround for [Bug 1904907].
	Reset the return option keys to NULL to allow full re-initialization
	by GetKeys(). This introduces a memory leak for the key objects, but
	gets us around a crash in the finalization of reflected channels when
	handling returns, either at compile- or runtime. In both cases we
	access the keys after they have been released by their thread exit
	handler. A proper fix is entangled with the untangling of the
	finalization ordering and attendant issues. For now we choose the
	lesser evil.

2008-03-07  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c (Tcl_ExprObj):	Revised expression bytecode
	compiling so that bytecodes invalid due to changing context or due to
	the difference between expressions and scripts are not reused. [Bug
	1899164]

	* generic/tclCmdAH.c:	Revised direct evaluation implementation of
	[expr] so that [expr $e] caches compiled bytecodes for the expression
	as the intrep of $e.

	* tests/execute.test (execute-6.*):	More tests checking that
	script bytecode is invalidated in the right situations.

2008-03-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* win/configure.in: Add AC_HEADER_STDC to support msys/win64.

2008-03-06  Donal K. Fellows  <dkf@users.sf.net>

	* doc/namespace.n: Minor tidying up. [Bug 1909019]

2008-03-04  Don Porter	<dgp@users.sourceforge.net>

	* tests/execute.test (6.3,4):	Added tests for [Bug 1899164].

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

	* unix/tclUnixChan.c: Fix mark and space parity on Linux, which uses
	CMSPAR instead of PAREXT.

2008-03-02  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclNamesp.c (GetNamespaceFromObj):
	* tests/interp.test (interp-28.2): Spoil the intrep of an nsNameType
	obj when the reference crosses interpreter boundaries.

2008-02-29  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclResult.c (Tcl_SetReturnOptions):	Revised the refcount
	management of Tcl_SetReturnOptions to become that of a conventional
	Consumer routine.  Thanks to Peter Spjuth for pointing out the
	difficulties calling Tcl_SetReturnOptions with non-0-count value for
	options.
	* generic/tclExecute.c (INST_RETURN_STK): Revised the one caller
	within Tcl itself which passes a non-0-count value to
	Tcl_SetReturnOptions().

	* generic/tclBasic.c (Tcl_AppendObjToErrorInfo):	Revised the
	refcount management of Tcl_AppendObjToErrorInfo to become that of a
	conventional Consumer routine. This preserves the ease of use for the
	overwhelming common callers who pass in a 0-count value, but makes the
	proper call with a non-0-count value less surprising.
	* generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd):	Revised the
	one caller within Tcl itself which passes a non-0-count value to
	Tcl_AppendObjToErrorInfo().

2008-02-28  Joe English  <jenglish@users.sourceforge.net>

	* unix/tclPort.h, unix/tclCompat.h, unix/tclUnixChan.h: Reduce scope
	of <sys/filio.h> and <sys/ioctl.h> #includes. [Patch 1903339]

	* unix/tclUnixChan.c, unix/tclUnixNotfy.c, unix/tclUnixPipe.c:
	Consolidate all code conditionalized on -DUSE_FIONBIO into one place.
	* unix/tclUnixPort.h, unix/tclUnixCompat.c: New routine
	TclUnixSetBlockingMode() [Patch 1903339].

2008-02-28  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c (TclEvalObjvInternal):	Plug memory leak when
	an enter trace deletes or changes the command, prompting a reparsing.
	Don't let the second pass lose commandPtr value allocated during the
	first pass.

	* generic/tclCompExpr.c (ParseExpr):	Plug memory leak in error
	message generation.

	* generic/tclStringObj.c (Tcl_AppendFormatToObj): [format %llx $big]
	leaked an mp_int.

	* generic/tclCompCmds.c (TclCompileReturnCmd):	The 2007-10-18 commit
	to optimize compiled [return -level 0 $x] [RFE 1794073] introduced a
	memory leak of the return options dictionary. Fixing that.

2008-02-27  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* library/http/http.tcl: [Bug 705956] - fix inverted logic when
	cleaning up socket error in geturl.

2008-02-27  Kevin B. Kenny  <kennykb@acm.org>

	* doc/clock.n: Corrected minor indentation gaffe in the penultimate
	paragraph. [Bug 1898025]

	clock value is in the range of a 64-bit integer. [Bug 1862555]
	* library/clock.tcl (::tcl::clock::format, ::tcl::clock::scan,
	(::tcl::clock::add, ::tcl::clock::LocalizeFormat): Fixed bugs in
	caching of localized strings that caused weird results when localized
	date/time formats were used. [Bug 1902423]
	* tests/clock.test (clock-61.*, clock-62.1): Regression tests for [Bug
	1862555] and [Bug 1902423].

	* generic/tclIOUtil.c, unix/tclUnixPort.h, unix/tclUnixChan.c:
	Remove dead/unused portability-related #defines and unused conditional
	code.  See [Patch 1901828] for discussion.

	* generic/tclIORChan.c (enum MethodName),
	* generic/tclCompExpr.c (enum Marks): More stray trailing ","s

2008-02-26  Joe English  <jenglish@users.sourceforge.net>

	* unix/configure.in(socklen_t test): Define socklen_t as "int" if

	* unix/configure: regenerated.

2008-02-26  Joe English  <jenglish@users.sourceforge.net>

	* generic/tclCompile.h: Remove stray trailing "," from enum

	determining right anchor. [Bug 1902436]

2008-02-26  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* library/http/pkgIndex.tcl: Set version 2.5.5
	* library/http/http.tcl:     It is better to do the [eof] check after
	trying to read from the socket. No clashes found in testing. Added
	http::meta command to access the http headers. [Bug 1868845]

2008-02-22  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* library/http/pkgIndex.tcl: Set version 2.5.4

	-exact -nocase option cannot be compiled currently. [Bug 1891827]

	* unix/README: Documented missing configure flags. [Bug 1799011]

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

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

	discussion on comp.lang.tcl.

2007-12-26  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCmdIL.c: More [lsort] data handling streamlines. The
	function MergeSort is gone, essentially inlined into Tcl_LsortObjCmd.
	It is not a straight inlining, two loops over all lists elements where
	merged in the process: the linked list elements are now built and
	merged into the temporary sublists in the same pass.

2007-12-25  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCmdIL.c: More [lsort] data handling streamlines. Extra
	mem reqs of latest patches removed, restored to previous mem profile.
	Improved -unique handling, now eliminating repeated elems immediately
	instead of marking them to avoid reinsertion at the end.

2007-12-23  Jeff Hobbs  <jeffh@ActiveState.com>

	sufficient length for the sorted list instead of growing it. Second
	commit replaces calls to Tcl_ListObjAppenElement with direct access to
	the internal rep.

2007-12-06  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>


	* generic/tclBasic.c (Tcl_CreateInterp): Simplify the setting up of
	* generic/tclIOCmd.c (TclInitChanCmd):	 the [chan] ensemble. This

	or C-stack depth detector).

2007-12-05  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/configure, win/tcl.m4 (LIBS_GUI): mingw needs -lole32

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

2007-11-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/makefile.vc: add ws2_32.lib to baselibs

	always available now.

2007-11-29  Don Porter	<dgp@users.sourceforge.net>

	buffer.

2007-11-28  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclConfig.c:	Corrected failure of the [::foo::pkgconfig]
	command to clean up registered configuration data when the query
	command is deleted from the interp. [Bug 983501]

	* generic/tclNamesp.c (Tcl_SetEnsembleMappingDict):	Added checks
	that the dict value passed in is in the format required to make the
	internals of ensembles work. [Bug 1436096]

	message in latest changes.

2007-11-28  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* generic/tclBasic.c: remove unneeded call in Tcl_CreateInterp, add
	comments.

2007-11-27  Don Porter	<dgp@users.sourceforge.net>

	* win/tclWinSock.c:	Add mising encoding conversion of the [info
	hostname] value from the system encoding to Tcl's internal encoding.

	* doc/chan.n:		"Fix" the limitation on channel -eofchar
	* doc/fconfigure.n:	values to single byte characters by documenting
	* generic/tclIO.c:	it and making it fail loudly. Thanks to Stuart
	* tests/chan.test:	Cassoff for contributing the fix. [Bug 800753]

2007-11-26  Miguel Sofer  <msofer@users.sf.net>

	Sergei Golovan (aka Teo) for detecting the bug and helping diagnose
	and develop the fix.

2007-11-24  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCompCmds.c (TclCompileDictAppendCmd): Fix bug in [dict
	append] compiler which caused strange stack corruption. [Bug 1837392]

2007-11-23  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIORChan.c: Fixed a problem with reflected channels. 'chan
	postevent' is defined to work only from within the interpreter
	containing the handler command. Sensible, we want only handler
	commands to use it. It identifies the channel by handle. The channel
	moves to a different interpreter or thread. The interpreter containing
	the handler command doesn't know the channel any longer. 'chan
	postevent' fails, not finding the channel any longer. Uhm.

	Fixed by creating a second per-interpreter channel table, just for
	reflected channels, where each interpreter remembers for which
	reflected channels it has the handler command. This info does not move
	with the channel itself. The table is updated by 'chan create', and
	used by 'chan postevent'.

	* tests/ioCmd.test: Updated the testsuite.

2007-11-23  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclVar.c (Tcl_ArrayObjCmd): handle the right data for
	* tests/var.test (var-14.2):          [array names $var -glob $ptn]

2007-11-23  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCmdMZ.c (String*Cmd, TclInitStringCmd): Rebuilt [string]
	* generic/tclCompCmds.c (TclCompileString*Cmd): as an ensemble.

2007-11-22  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclDictObj.c (Dict*Cmd,TclInitDictCmd): Rebuilt the [dict]
	* generic/tclCompCmds.c (TclCompileDict*Cmd): command as an ensemble.

2007-11-22  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCmdMZ.c (Tcl_StringObjCmd): Rewrote the [string] and
	* generic/tclDictObj.c (Tcl_DictObjCmd): [dict] implementations to be
	ready for conversion to ensembles.

	* tests/string.test (string-12.22): Flag shimmering bug found in
	[string range].

2007-11-21  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCompCmds.c (TclCompileEnsemble): Rewrote the ensemble
	compiler to remove many of the limitations. Can now compile scripts
	that use unique prefixes of subcommands, and which have mappings of a
	command to multiple words (provided the first is a compilable command
	of course).

2007-11-21  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclNamesp.c (TclMakeEnsemble): Factor out the code to set up
	a core ensemble from a table of information about subcommands, ready
	for reuse within the core.

	* generic/various: Start to return more useful Error codes, currently
	mainly on assorted lookup failures.

2007-11-20  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclDictObj.c: Changed the underlying implementation of the
	hash table used in dictionaries to additionally keep all entries in
	the hash table in a linked list, which is only ever added to at the
	end. This makes iteration over all entries in the dictionary in
	key insertion order a trivial operation, and so cleans up a great deal
	of complexity relating to dictionary representation and stability of
	iteration order.

	***POTENTIAL INCOMPATIBILITY***
	For any code that depended on the (strange) old iteration order.

	* generic/tclConfig.c (QueryConfigObjCmd): Correct usage of
	Tcl_WrongNumArgs.

2007-11-19  Don Porter	<dgp@users.sourceforge.net>

	traces not firing on non-existent array elements. [Bug 1833522]

2007-11-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCmdIL.c (TclInitInfoCmd): Rename the implementation
	commands for [info] to be something more "expected".

	* generic/tclCompCmds.c (TclCompileInfoExistsCmd): Compiler for the
	[info exists] subcommand.
	(TclCompileEnsemble): Cleaned up version of ensemble compiler that was
	in TclCompileInfoCmd, but which is now much more generally applicable.

	* generic/tclInt.h (ENSEMBLE_COMPILE): Added flag to allow for cleaner
	turning on and off of ensemble bytecode compilation.

	* generic/tclCompile.c (TclCompileScript): Add the cmdPtr to the list
	of arguments passed to command compilers.

2007-11-15  Don Porter	<dgp@users.sourceforge.net>

	avoid wasting time walking a list of dead states. [Bug 1832612]

2007-11-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclNamesp.c (NamespaceEnsembleCmd): Must pass a non-NULL
	interp to Tcl_SetEnsemble* functions.

	* doc/re_syntax.n: Try to make this easier to read. It's still a very
	difficult manual page!

	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Allow people to turn off the -rpath
	option to their linker if they so desire. This is a configuration only
	recommended for (some) vendors. Relates to [Patch 1231022].

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

	* win/tclWin32Dll.c: Prefer UINT_PTR to DWORD_PTR when casting pointers
	to integer types for greater portability. [Bug 1831253]

2007-11-15  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.xcodeproj/project.pbxproj: add new chanio.test.
	* macosx/Tcl.xcode/project.pbxproj:

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

	* generic/tclCompile.c (TclCompileScript): Ensure that we get our count
	in our INST_START_CMD calls right, even when there's a failure to
	compile a command directly.

	* generic/tclNamesp.c (Tcl_SetEnsembleSubcommandList)
	(Tcl_SetEnsembleMappingDict):		Special code to make sure that
	* generic/tclCmdIL.c (TclInitInfoCmd):	[info exists] is compiled right
	while not allowing changes to the ensemble to cause havok.

	* generic/tclCompCmds.c (TclCompileInfoCmd): Simple compiler for the
	[info] command that only handles [info exists].

	* generic/tclExecute.c (TclExecuteByteCode:INST_EXIST_*): New
	instructions to allow the testing of whether a variable exists.

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

	* tests/chanio.test: New file. This is essentially a duplicate of
	'io.test', with all channel commands converted to their 'chan xxx'
	notation.
	* tests/io.test: Fixed typo in test description.

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

	* generic/regc*.c: Eliminate multi-char collating element code
	completely. Simplifies the code quite a bit. If people still want the
	full code, it will remain on the 8.4 branch. [Bug 1831425]

2007-11-13  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclCompCmds.c (TclCompileRegexpCmd): clean up comments, only
	free dstring on OK from TclReToGlob.
	(TclCompileSwitchCmd): simplify TclReToGlob usage.

2007-11-14  Donal K. Fellows  <dkf@users.sf.net>

	* generic/regc*.c: #ifdef/comment out the code that deals with
	multi-character collating elements, which have never been supported.
	Cuts the memory consumption of the RE compiler. [Bug 1831425]

2007-11-13  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCompCmds.c (TclCompileSwitchCmd, TclCompileRegexpCmd):
	Extend [switch] compiler to handle regular expressions as long as
	things are not too complex. Fix [regexp] compiler so that non-trivial
	literal regexps get fed to INST_REGEXP.

	* doc/mathop.n: Clarify definitions of some operations.

2007-11-13  Miguel Sofer  <msofer@users.sf.net>

	* unix/tclUnixInit.c: the TCL_NO_STACK_CHECK was being incorrectly
	undefined here; this should be set (or not) in the compile options, it
	is used elsewhere and needs to be consistent.

2007-11-13  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* unix/tcl.m4:		Added autoconf goo to detect and make use of
	* unix/configure.in:	getaddrinfo and friends.
	* unix/configure:	(regenerated)

2007-11-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/tclUnixCompat.c (TclpGetHostByName): The six-argument form of
	getaddressbyname_r() uses the fifth argument to indicate whether the
	lookup succeeded or not on at least one platform. [Bug 1618235]

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

	* generic/regcomp.c:	Convert optst() from expensive no-op to a
	cheap no-op.

2007-11-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/tclUnixChan.c (CreateSocketAddress): Rewrote to use the
	thread-safe version of gethostbyname() by forward-porting the code used
	in 8.4, and added rudimentary support for getaddrinfo() (not enabled by
	default, as no autoconf-ery written). Part of fix for [Bug 1618235].

2007-11-12  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclGet.c (Tcl_Get, Tcl_GetInt): revert use of TclGet* macros
	due to compiler warning. These cases won't save time either.

	* generic/tclUtil.c (TclReToGlob): add more comments, set interp result
	if specified on error.

2007-11-12  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:		New macro TclResetResult, new iPtr flag
	* generic/tclExecute.c:		bit INTERP_RESULT_UNCLEAN: shortcut for
	* generic/tclInt.h:		Tcl_ResetResult for the "normal" case:
	* generic/tclProc.c:		TCL_OK, no return options, no errorCode
	* generic/tclResult.c:		nor errorInfo, return at normal level.
	* generic/tclStubLib.c:		[Patch 1830184]
	* generic/tclUtil.c:

	THIS PATCH WAS REVERTED: initial (mis)measurements overstated the
	perfomance wins, which turn out to be tiny. Not worth the complication.

2007-11-11  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclCompCmds.c, generic/tclCompile.c, generic/tclCompile.h:
	* generic/tclExecute.c, generic/tclInt.decls, generic/tclIntDecls.h:
	* generic/tclRegexp.c, generic/tclRegexp.h: Add INST_REGEXP and fully
	* generic/tclStubInit.c, generic/tclUtil.c: compiled [regexp] for the
	* tests/regexpComp.test:     [Bug 1830166]  simple cases. Also added
	TclReToGlob function to convert RE to glob patterns and use these in
	the possible cases.

2007-11-11  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclResult.c (ResetObjResult): clarify the logic.

	* generic/tclBasic.c:		Increased usage of macros to detect
	* generic/tclBinary.c:		and take advantage of objTypes. Added
	* generic/tclClock.c:		macros TclGet(Int|Long)FromObj,
	* generic/tclCmdAH.c:		TclGetIntForIndexM & TclListObjLength,
	* generic/tclCmdIL.c:		modified TclListObjGetElements.
	* generic/tclCmdMZ.c:
	* generic/tclCompCmds.c:	The TclGetInt* macros are only a
	* generic/tclCompExpr.c:	shortcut on platforms where 'long' is
	* generic/tclCompile.c:		'int'; it may be worthwhile to extend
	* generic/tclDictObj.c:		their functionality to other cases.
	* generic/tclExecute.c:
	* generic/tclGet.c:		As this patch touches many files it has
	* generic/tclIO.c:		been recorded as [Patch 1830038] in
	* generic/tclIOCmd.c:		order to facilitate reviewing.
	* generic/tclIOGT.c:

2007-11-11  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclUnixTime.c (TclpWideClicksToNanoseconds): Fix issues with
	* generic/tclInt.h:				    int64_t overflow.

	* generic/tclBasic.c:	Fix stack check failure case if stack grows up
	* unix/tclUnixInit.c:	Simplify non-crosscompiled case.

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

2007-11-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: Fast path for INST_LIST_INDEX when the index is
	not a list.

	* generic/tclBasic.c:
	* unix/configure.in:
	* unix/tclUnixInit.c: Detect stack grwoth direction at compile time,
	only fall to runtime detection when crosscompiling.

	* unix/configure: autoconf 2.61

	* generic/tclBasic.c:
	* generic/tclInt.h:
	* tests/interp.test:
	* unix/tclUnixInit.c:
	* win/tclWin32Dll.c: Restore simpler behaviour for stack checking, not
	adaptive to stack size changes after a thread is launched. Consensus is
	that "nobody does that", and so it is not worth the cost. Improved
	failure comments (mistachkin).

2007-11-10  Kevin Kenny  <kennykb@acm.org>

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

2007-11-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:
	* generic/tclInt.h:
	* unix/tclUnixInit.c:
	* unix/tclUnixPort.h:
	* win/tclWin32Dll.c: Modify the stack checking algorithm to recheck in
	case of failure. The working assumptions are now that (a) a thread's
	stack is never moved, and (b) a thread's stack can grow but not shrink.
	Port to windows - could be more efficient, but is already cheaper than
	it was.

2007-11-09  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclResult.c (ResetObjResult): new shortcut.

	* generic/tclAsync.c:
	* generic/tclBasic.c:
	* generic/tclExecute.c:
	* generic/tclInt.h:
	* generic/tclUnixInit.c:
	* generic/tclUnixPort.h: New fields in interp (ekeko!) to cache TSD
	data that is accessed at each command invocation, access macros to
	replace Tcl_AsyncReady and TclpCheckStackSpace by much faster variants.
	[Patch 1829248]

2007-11-09  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclInt.decls, generic/tclIntDecls.h: Use unsigned char for
	* generic/tclExecute.c, generic/tclUtil.c:     TclByteArrayMatch and
	don't allow a nocase option. [Bug 1828296]
	For INST_STR_MATCH, ignore pattern type for TclByteArrayMatch case.

	* generic/tclBinary.c (Tcl_GetByteArrayFromObj): check type before
	func jump (perf).

2007-11-07  Jeff Hobbs  <jeffh@ActiveState.com>

	* generic/tclStubInit.c:			Added TclByteArrayMatch
	* generic/tclInt.decls:				for efficient glob
	* generic/tclIntDecls.h:			matching of ByteArray
	* generic/tclUtil.c (TclByteArrayMatch):	Tcl_Objs, used in
	* generic/tclExecute.c (TclExecuteByteCode):	INST_STR_MATCH. [Bug
							1827996]

	* generic/tclIO.c (TclGetsObjBinary): Add an efficient binary path for
					      [gets].
	(DoWriteChars): Special case for 1-byte channel write.

2007-11-06  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclEncoding.c: Version of the embedded iso8859-1 encoding
	handler that is faster (functions to do the encoding know exactly what
	they're doing instead of pulling it from a table, though the table
	itself has to be retained for use by shift encodings that depend on
	iso8859-1). [Patch 1826906], committing for dkf.

2007-11-05  Andreas Kupries  <andreask@activestate.com>

	* generic/tclConfig.c (Tcl_RegisterConfig): Modified to not extend the
	config database if the encoding provided by the user is not found
	(venc == NULL). Scripts expecting the data will error out, however we
	neither crash nor provide bogus information. See [Bug 983509] for more
	discussion.

	* unix/tclUnixChan.c (TtyGetOptionProc): Accepted [Patch 1823576]
	provided by Stuart Cassof <stwo@users.sourceforge.net>. The patch adds
	the necessary utf/external conversions to the handling of the arguments
	of option -xchar which will allow the use of \0 and similar characters.

2007-11-03  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclTest.c (TestSetCmd2):
	* generic/tclVar.c (TclObjLookupVarEx):
	* tests/set.test (set-5.1): Fix error branch when array name looks
	like array element (code not normally exercised).

2007-11-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tools/tcltk-man2html.tcl (output-directive): Convert .DS/.DE pairs
	into tables since that is now all that they are used for.

	* doc/RegExp.3: Clarified documentation of RE flags. [Bug 1167840]

	* doc/refchan.n: Adjust internal name to be consistent with the file
	name for reduced user confusion. After comment by Dan Steffen.

	* generic/tclCmdMZ.c (Tcl_StringObjCmd, UniCharIsAscii): Remember, the
	NUL character is in ASCII too. [Bug 1808258]

	* doc/file.n: Clarified use of [file normalize]. [Bug 1185154]

2007-10-30  Don Porter	<dgp@users.sourceforge.net>

	* generic/tcl.h:	Bump version number to 8.5b2.1 to distinguish
	* library/init.tcl:	CVS development snapshots from the 8.5b2
	* unix/configure.in:	release.
	* unix/tcl.spec:
	* win/configure.in:

	* unix/configure:	autoconf (2.59)
	* win/configure:

2007-10-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/expr.n, doc/mathfunc.n: Improve documentation to try to make
	clearer what is going on.

	* doc/interp.n: Shorten the basic descriptive text for some interp
	subcommands so Solaris nroff doesn't truncate them. [Bug 1822268]

2007-10-30  Donal K. Fellows  <dkf@users.sf.net>

	* tools/tcltk-man2html.tcl (output-widget-options): Enhance the HTML
	generator so that it can produce multi-line option descriptions.

2007-10-28  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclUtil.c (Tcl_ConcatObj): optimise for some of the
	concatenees being empty objs. [Bug 1447328]

2007-10-28  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclEncoding.c (TclInitEncodingSubsystem): Hard code the
	iso8859-1 encoding, as it's needed for more than just text (especially
	binary encodings...) Note that other encodings rely on the encoding
	being a table encoding (!) so we can't use more efficient encoding
	mapping functions.

2007-10-27  Donal K. Fellows  <dkf@users.sf.net>

	* generic/regc_lex.c (lexescape): Close off one of the problems
	mentioned in [Bug 1810264].

2007-10-27  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclNamesp.c (Tcl_FindCommand): insure that FQ command names
	are searched from the global namespace, ie, bypassing resolvers of the
	current namespace. [Bug 1114355]

	* doc/apply.n: fixed example [Bug 1811791]
	* doc/namespace.n: improved example [Bug 1788984]
	* doc/AddErrInfo.3: typo [Bug 1715087]
	* doc/CrtMathFnc.3: fixed Tcl_ListMathFuncs entry [Bug 1672219]

	* generic/tclCompile.h:
	* generic/tclInt.h: moved declaration of TclSetCmdNameObj from
	tclCompile.h to tclInt.h, reverting linker [Bug 1821159] caused by
	commit of 2007-10-11 (both I and gcc missed one dep).

	* generic/tclVar.c: try to preserve Tcl_Objs when doing variable
	lookups by name, partially addressing [Bug 1793601].

2007-10-27  Donal K. Fellows  <dkf@users.sf.net>

	* tools/tcltk-man2html.tcl (make-man-pages, htmlize-text)

	to do man->other formats work better with current manpage set. Long
	way still to go.

2007-10-25  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

	* generic/tclThread.c: Added TclpMasterLock/Unlock arround calls to
	ForgetSyncObject in Tcl_MutexFinalize and Tcl_ConditionFinalize to
	prevent from garbling the internal lists that track sync objects. [Bug
	1726873]

2007-10-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* win/makefile.vc, win/rules.vc, win/nmakehlp.c: Use nmakehlp to
	substitute values for tclConfig.sh (helps cross-compiling).

2007-09-11  Don Porter	<dgp@users.sourceforge.net>

	* library/tcltest/tcltest.tcl:	Accept underscores and colons in
	* library/tcltest/pkgIndex.tcl: constraint names. Properly handle
	constraint expressions that return non-numeric boolean results like
	"false". Bump to tcltest 2.3b1. [Bug 1772989; RFE 1071322]
	* tests/info.test:	Disable fragile tests.

	* doc/package.n:	Restored the functioning of [package require
	* generic/tclPkg.c:	-exact] to be compatible with Tcl 8.4. [Bug
	* tests/pkg.test:	1578344]

2007-09-11  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompCmds.c (TclCompileDictCmd-update):
	* generic/tclCompile.c (tclInstructionTable):
	* generic/tclExecute.c (INST_DICT_UPDATE_END): fix stack management in
	compiled [dict update]. [Bug 1786481]

	***POTENTIAL INCOMPATIBILITY***
	Scripts that were precompiled on earlier versions of 8.5 and use [dict
	update] will crash. Workaround: recompile.

2007-09-11  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclExecute.c: Corrected an off-by-one error in the setting
	of MaxBaseWide for certain powers. [Bug 1767293 - problem reported in
	comments when bug was reopened]

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

	* generic/tclLink.c (Tcl_UpdateLinkedVar): guard against var being
	unlinked. [Bug 1740631] (maros)

2007-09-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompile.c: fix tclInstructionTable entry for
	dictUpdateEnd

	* generic/tclExecute.c: remove unneeded setting of 'cleanup' variable
	before jumping to checkForCatch.

2007-09-10  Don Porter	<dgp@users.sourceforge.net>

	* doc/package.n:	Restored the document parallel syntax of the
	* generic/tclPkg.c:	[package present] and [package require]
	* tests/pkg.test:	commands. [Bug 1723675]

2007-09-09  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclInt.h:	Removed the "nsName" Tcl_ObjType from the
	* generic/tclNamesp.c:	registered set. Revised the management of the
	* generic/tclObj.c:	intrep of that Tcl_ObjType. Revised the
	* tests/obj.test:	TclGetNamespaceFromObj() routine to return
	TCL_ERROR and write a consistent error message when a namespace is not
	found. [Bug 1588842. Patch 1686862]

	***POTENTIAL INCOMPATIBILITY***
	For callers of Tcl_GetObjType() on the name "nsName".

	* generic/tclExecute.c: Update TclGetNamespaceFromObj() callers.
	* generic/tclProc.c:

	* tests/apply.test:		Updated tests to expect new consistent
	* tests/namespace-old.test:	error message when a namespace is not
	* tests/namespace.test:		found.
	* tests/upvar.test:

	* generic/tclCompCmds.c:	Use the new INST_REVERSE instruction
	* tests/mathop.test:	to correct the compiled versions of math
	operator commands. [Bug 1724437]

	* generic/tclCompile.c: New bytecode instruction INST_REVERSE to
	* generic/tclCompile.h: reverse the order of N items at the top of
	* generic/tclExecute.c: stack.

	* generic/tclCompCmds.c (TclCompilePowOpCmd):	Make a separate
	routine to compile ** to account for its different associativity.

2007-09-08  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (Tcl_SetVar2, TclPtrSetVar): [Bug 1710710] fixed
	correctly, reverted fix of 2007-05-01.

2007-09-08  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclDictObj.c (DictUpdateCmd, DictWithCmd): Plug a hole that
	* generic/tclExecute.c (TEBC,INST_DICT_UPDATE_END): allowed a careful
	* tests/dict.test (dict-21.16,21.17,22.11): attacker to craft a dict
	containing a recursive link to itself, violating one of Tcl's
	fundamental datatype assumptions and causing a stack crash when the
	dict was converted to a string. [Bug 1786481]

2007-09-07  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclEvent.c ([::tcl::Bgerror]):	Corrections to Tcl's
	* tests/event.test:	default [interp bgerror] handler so that when
	it falls back to a hidden [bgerror] in a safe interp, it gets the
	right error context data. [Bug 1790274]

2007-09-07  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclProc.c (TclInitCompiledLocals): the refCount of resolved
	variables was being managed without checking if they were Var or
	VarInHash: itcl [Bug 1790184]

2007-09-06  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclResult.c (Tcl_GetReturnOptions):	Take care that a
	* tests/init.test:	non-TCL_ERROR code doesn't cause existing
	-errorinfo, -errorcode, and -errorline entries to be omitted.
	* generic/tclEvent.c:	With -errorInfo no longer lost, generate more
	complete ::errorInfo when calling [bgerror] after a non-TCL_ERROR
	background exception.

2007-09-06  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclInterp.c (Tcl_Init):	Removed constraint on ability
	to define a custom [tclInit] before calling Tcl_Init(). Until now the
	custom command had to be a proc. Now it can be any command.

	* generic/tclInt.decls: New internal routine TclBackgroundException()
	* generic/tclEvent.c:	that for the first time permits non-TCL_ERROR
	exceptions to trigger [interp bgerror] handling. Closes a gap in TIP
	221. When falling back to [bgerror] (which is designed only to handle
	TCL_ERROR), convert exceptions into errors complaining about the
	exception.

	* generic/tclInterp.c:	Convert Tcl_BackgroundError() callers to call
	* generic/tclIO.c:	TclBackgroundException().
	* generic/tclIOCmd.c:
	* generic/tclTimer.c:

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

2007-09-06  Daniel Steffen  <das@users.sourceforge.net>

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

	* macosx/Tcl.xcodeproj/project.pbxproj: updates for Xcode 2.5 and 3.0.
	* macosx/Tcl.xcodeproj/default.pbxuser:
	* macosx/Tcl.xcode/project.pbxproj:
	* macosx/Tcl.xcode/default.pbxuser:
	* macosx/Tcl-Common.xcconfig:

	* macosx/README: document project changes.

2007-09-05  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Removed support for the unmaintained
	* generic/tclExecute.c: -DTCL_GENERIC_ONLY configuration. [Bug
	* unix/Makefile.in:	1264623]

2007-09-04  Don Porter	<dgp@users.sourceforge.net>

	* unix/Makefile.in:	It's unreliable to count on the release
	manager to remember to `make genstubs` before `make dist`. Let the
	Makefile remember the dependency for us.

	* unix/Makefile.in:	Corrections to `make dist` dependencies to be
	sure that macosx/configure gets generated whenever it does not exist.

2007-09-03  Kevin B, Kenny  <kennykb@acm.org>

	* generic/tclListObj.c (TclLindexFlat):
	* tests/lindex.test (lindex-17.[01]):	Added code to detect the error
	when a script does [lindex {} end foo]; an overaggressive optimisation
	caused this call to return an empty object rather than an error.

2007-09-03  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclObj.c (TclInitObjSubsystem): restore registration of the
	"wideInt" Tcl_ObjType for compatibility with 8.4 extensions that
	access the tclWideIntType Tcl_ObjType; add setFromAnyProc for
	tclWideIntType.

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

	* doc/lsearch.n: Added note that order of results with the -all option
	is that of the input list. It always was, but this makes it crystal.

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

	* generic/tclCompile.c: Added fflush() calls following all callers of
	* generic/tclExecute.c: TclPrintByteCodeObj() so that tcl_traceCompile
	output is less likely to get mangled when writes to stdout interleave
	with other code.

2007-08-28  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Use a table lookup in ParseLexeme() to
	determine lexemes with single-byte representations.

	* generic/tclBasic.c:	Used unions to better clarify overloading of
	* generic/tclCompExpr.c:	the fields of the OpCmdInfo and
	* generic/tclCompile.h:		TclOpCmdClientData structs.

2007-08-27  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Call TclCompileSyntaxError() when
	expression syntax errors are found when compiling expressions. With
	this in place, convert TclCompileExpr to return void, since there's no
	longer any need to report TCL_ERROR.
	* generic/tclCompile.c: Update callers.
	* generic/tclExecute.c:

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

	* generic/tclCompile.c: Move the deallocation of local LiteralTable
	* generic/tclCompExpr.c:	entries into TclFreeCompileEnv().
	* generic/tclExecute.c: Update callers.

	* generic/tclCompExpr.c:	Force numeric and boolean literals in
	expressions to register with their intreps intact, even if that means
	overwriting existing intreps in already registered literals.

2007-08-25  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclExecute.c (TclExecuteByteCode): Added code to handle
	* tests/expr.test (expr-23.48-53)	     integer exponentiation
	that results in 32- and 64-bit integer results, avoiding calls to wide
	integer exponentiation routines in this common case. [Bug 1767293]

	* library/clock.tcl (ParseClockScanFormat): Modified code to allow
	* tests/clock.test (clock-60.*):	    case-insensitive matching
	of time zone and month names. [Bug 1781282]

2007-08-24  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Register literals found in expressions
	* tests/compExpr.test:	to restore literal sharing. Preserve numeric
	intreps when literals are created for the first time. Correct memleak
	in ExecConstantExprTree() and add test for the leak.

2007-08-24  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompile.c: replaced copy loop that tripped some compilers
	with memmove. [Bug 1780870]

2007-08-23  Don Porter	<dgp@users.sourceforge.net>

	* library/init.tcl ([auto_load_index]): Delete stray "]" that created
	an expr syntax error (masked by a [catch]).

	* generic/tclCompCmds.c (TclCompileReturnCmd):	Added crash protection
	to handle callers other than TclCompileScript() failing to meet the
	initialization assumptions of the TIP 280 code in CompileWord().

	* generic/tclCompExpr.c:	Suppress the attempt to convert to
	numeric when pre-compiling a constant expresion indicates an error.

2007-08-22  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (TEBC): disable the new shortcut to frequent
	INSTs for debug builds. REVERTED (collision with alternative fix)

2007-08-21  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclMain.c:	Corrected the logic of dropping the last
	* tests/main.test:	newline from an interactively typed command.
	[Bug 1775878]

2007-08-21  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* tests/thread.test: thread-4.4: clear ::errorInfo in the thread as a
	message is left here from init.tcl on windows due to no tcl_pkgPath.

2007-08-20  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (INST_SUB): fix usage of the new macro for
	overflow detection in sums, adapt to subtraction. Lengthy comment
	added.

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

	* generic/tclExecute.c (Overflowing, TclIncrObj, TclExecuteByteCode):
	Encapsulate Miguel's last change in a more mnemonic macro.

2007-08-19  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: changed the check for overflow in sums,
	reducing objsize, number of branches and cache misses (according to
	cachegrind). Non-overflow for s=a+b:
	previous
	  ((a >= 0 || b >= 0 || s < 0) && (s >= 0 || b < 0 || a < 0))
	now
	  (((a^s) >= 0) || ((a^b) < 0))
	This expresses: "a and s have the same sign or else a and b have
	different sign".

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

	* doc/interp.n (RESOURCE LIMITS): Added text to better explain why
	time limits are described using absolute times. [Bug 1752148]

2007-08-16  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c: improved localVarNameType caching to leverage
	the new availability of Tcl_Obj in variable names, avoiding string
	comparisons to verify that the cached value is usable.

	* generic/tclExecute.c: check the two most frequent instructions
	before the switch. Reduces both runtime and obj size a tiny bit.

2007-08-16  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Added a "constant" field to the OpNode
	struct (again "free" due to alignment requirements) to mark those
	subexpressions that are completely known at compile time. Enhanced
	CompileExprTree() and its callers to precompute these constant
	subexpressions at compile time. This resolves the issue raised in [Bug
	1564517].

2007-08-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclIOUtil.c (TclGetOpenModeEx): Only set the O_APPEND flag
	* tests/ioUtil.test (ioUtil-4.1):	  on a channel for the 'a'
	mode and not for 'a+'. [Bug 1773127]

2007-08-14  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (INST_INVOKE*): peephole opt, do not get the
	interp's result if it will be pushed/popped.

2007-08-14  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Use fully qualified variable names for
	* tests/thread.test:	::errorInfo and ::errorCode so that string
	* tests/trace.test:	reported to variable traces are fully
	qualified in agreement with Tcl 8.4 operations.

2007-08-14  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclLoadDyld.c: use dlfcn API on Mac OS X 10.4 and later; fix
	issues with loading from memory on intel and 64bit; add debug messages

	* tests/load.test: add test load-10.1 for loading from vfs.

	* unix/dltest/pkga.c:		whitespace & comment cleanup, remove
	* unix/dltest/pkgb.c:		unused pkgf.c.
	* unix/dltest/pkgc.c:

	* generic/tclExecute.c: Provide DECACHE/CACHE protection to the
	* tests/trace.test:	Tcl_LogCommandInfo() call. [Bug 1773040]

2007-08-12  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCmdMZ.c (Tcl_SplitObjCmd): use TclNewStringObj macro
	instead of calling the function.

	* generic/tcl_Obj.c (TclAllocateFreeObjects): remove unneeded memset
	to 0 of all allocated objects.

2007-08-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInt.h: remove redundant ops in TclNewStringObj macro.

2007-08-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInt.h: fix the TclSetVarNamespaceVar macro, was causing a
	leak.

2007-08-10  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Revise CompileExprTree() to use the
	OpNode mark field scheme of tree traversal. This eliminates the need
	to use magic values in the left and right fields for that purpose.
	Also stop abusing the left field within ParseExpr() to store the
	number of arguments in a parsed function call. CompileExprTree() now
	determines that for itself at compile time. Then reorder code to
	eliminate duplication.

2007-08-09  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclProc.c (TclCreateProc): better comments on the required
	varflag values when loading precompiled procs.

	* generic/tclExecute.c (INST_STORE_ARRAY):
	* tests/trace.test (trace-2.6): whole array write traces on compiled
	local variables were not firing. [Bug 1770591]

2007-08-08  Jeff Hobbs	<jeffh@ActiveState.com>

	* generic/tclProc.c (InitLocalCache): reference firstLocalPtr via
	procPtr. codePtr->procPtr == NULL exposed by tbcload.

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

	* generic/tclExecute.c: Corrected failure to compile/link in the
	-DNO_WIDE_TYPE configuration.

	* generic/tclExecute.c: Corrected improper use of bignum arguments to
	* tests/expr.test:	*SHIFT operations. [Bug 1770224]

2007-08-07  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInt.h: remove comments refering to VAR_SCALAR, as that
	flag bit does not exist any longer.
	* generic/tclProc.c (InitCompiledLocals): removed optimisation for
	non-resolved case, as the function is never called in that case.
	Renamed the function to InitResolvedLocals to calrify the point.

	* generic/tclInt.decls:	  Exporting via stubs to help xotcl adapt to
	* generic/tclInt.h:	  VarReform.
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c:

2007-08-07  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclEnv.c:	improve environ handling on Mac OS X (adapted
	* unix/tclUnixPort.h:	from Apple changes in Darwin tcl-64).

	* unix/Makefile.in:	add support for compile flags specific to
				object files linked directly into executables.

	* unix/configure.in (Darwin): only use -seg1addr flag when prebinding;
	use -mdynamic-no-pic flag for object files linked directly into exes;
	support overriding TCL_PACKAGE_PATH/TCL_MODULE_PATH in environment.

	* unix/configure: autoconf-2.59

2007-08-06  Don Porter	<dgp@users.sourceforge.net>

	* tests/parseExpr.test: Update source file name of expr parser code.

	* generic/tclCompExpr.c:	Added a "mark" field to the OpNode
	struct, which is used to guide tree traversal. This field costs
	nothing since alignement requirements used the memory already.
	Rewrote ConvertTreeToTokens() to use the new field, which permitted
	consolidation of utility routines CopyTokens() and
	GenerateTokensForLiteral().

2007-08-06  Kevin B. Kenny  <kennykb@users.sf.net>

	* generic/tclGetDate.y: Added a cast to the definition of YYFREE to
				silence compiler warnings.
	* generic/tclDate.c:	Regenerated
	* win/tclWinTest.c:	Added a cast to GetSecurityDescriptorDacl call
				to silence compiler warnings.

2007-08-04  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInt.decls:	  Exporting via stubs to help itcl adapt to
	* generic/tclInt.h:	  VarReform. Added localCache initialization
	* generic/tclIntDecls.h:  to TclInitCompiledLocals (which only exists
	* generic/tclProc.c:	  for itcl).
	* generic/tclStubInit.c:
	* generic/tclVar.c:

2007-08-01  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* library/word.tcl: Rewrote for greater efficiency. [Bug 1764318]

2007-08-01  Pat Thoyts	<patthoyts@users.sourceforge.net>

	* generic/tclInt.h:	Added a TclOffset macro ala Tk_Offset to
	* generic/tclVar.c:	abstract out 'offsetof' which may not be
	* generic/tclExceute.c: defined (eg: msvc6).

2007-08-01  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (TclCleanupVar): fix [Bug 1765225], thx Larry
	Virden.

2007-07-31  Miguel Sofer  <msofer@users.sf.net>

	* doc/Hash.3:
	* generic/tclHash.c:
	* generic/tclObj.c:
	* generic/tclThreadStorage.c: (changes part of the patch below)
	Stop Tcl_CreateHashVar from resetting hPtr->clientData to NULL after
