2006-09-27  Miguel Sofer  <msofer@users.sf.net>

	* generic/regc_color.c (singleton):
	* generic/regc_cvec.c (addmcce):
	* generic/regcomp.c (compile, dovec): the static function addmcce does
	nothing when called with two NULL pointers; the only call is by
	compile with two NULL pointers (regcomp.c #includes
	regc_cvec.c). 
	Large parts (all?) the code for mcce (multi character collating
	element) that we do not use is ifdef'ed out with the macro
	REGEXP_MCCE_ENABLE. 
	This silences coverity bugs 7, 16, 80 

	* generic/regc_color.c (uncolorchain):
	* generic/regc_nfa.c (freearc): changed tests and asserts to
	equivalent formulation, designed to avoid an explicit comparison
	to NULL and satisfy coverity that 6 and 9 are not bugs.

2006-09-27  Andreas Kupries  <andreask@activestate.com>

	* tests/pkg.test: Added test for version comparison at the 32bit
	  boundary. [SF Tcl Bug 1563836].

	* generic/tclPkg.c: [SF Tcl Bug 1563836]. Rewrote CompareVersion
	  to perform string comparison instead of numeric. This breaks
	  through the 32bit limit on version numbers. See code for details
	  (handling of leading zeros, signs, etc.). un-CONSTed some
	  arguments of CompareVersions, RequirementSatisfied, and
	  AllRequirementsSatisfied. The new compare modifies the string
	  (temporary string terminators). All callers use heap-allocated
	  ver-intreps, so we are good with that.

2006-09-27  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclFileName.c (TclGlob): added a panic for a call with
	TCL_GLOBMODE_TAILS and pathPrefix==NULL. This would cause a
	segfault, as found by coverity #26.

2006-09-26  Kevin Kenny  <kennykb@acm.org>

	* doc/Encoding.3:        Added covariant 'const' qualifier for the
	* generic/tcl.decls:     Tcl_EncodingType argument to
	* generic/tclEncoding.c: Tcl_CreateEncoding. [Further TIP#27 work.]
	* generic/tclDecls.h:    Reran 'make genstubs'.
	
2006-09-26  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/makefile.vc:  Additional compiler flags and amd64 support.
	* win/nmakehlp.c:
	* win/rules.vc:

2006-09-26  Don Porter  <dgp@users.sourceforge.net>

        * generic/tcl.h:        As 2006-09-22 commit from Donal K. Fellows
        demonstrates, "#define NULL 0" is just wrong, and as a quotable chat
        figure observed, "If NULL isn't defined, we're not using a C compiler."
        Improper fallback definition of NULL removed.

2006-09-25  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* generic/tcl.h:        More fixing which struct stat to refer to.
	* generic/tclGetDate.y: Some casts from time_t to int required.
	* generic/tclTimer.c:   Tcl_Time structure members are longs.
	* win/makefile.vc:      Support for varying compiler options
	* win/rules.vc:         and build to platform-specific subdirs.

2006-09-25  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c (Tcl_StackChannel): Fixed [SF Tcl Bug 1564642],
	  aka coverity #51. Extended loop condition, added checking for
	  NULL to prevent seg.fault.

2006-09-25  Andreas Kupries  <andreask@activestate.com>

	* doc/package.n: Fixed nits reported by Daniel Steffen in the
	  TIP#268 changes.

2006-09-25  Kevin B. Kenny   <kennykb@acm.org>

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

	* generic/tclNotify.c (Tcl_DeleteEvents): Make it clear what happens
	when the event queue is mismanaged. [Bug 1564677], coverity bug #10.

2006-09-24  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclParse.c (Tcl_ParseCommand): also return an error if
	start==NULL and numBytes<0. This is coverity's bug #20

	* generic/tclStringObj.c (STRING_SIZE): fix allocation for 0-length
	strings. This is coverity's bugs #54-5

2006-09-22  Andreas Kupries  <andreask@activestate.com>

	* generic/tclInt.h: Moved TIP#268's field 'packagePrefer' to the end
	of the structure, for better backward compatibility.

2006-09-22  Andreas Kupries  <andreask@activestate.com>

	TIP#268 IMPLEMENTATION

2006-09-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclThreadTest.c (TclCreateThread): Use NULL instead of 0 as
	end-of-strings marker to Tcl_AppendResult; the difference matters on
	64-bit machines. [Bug 1562528]

2006-09-21  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclUtil.c:	Dropped ParseInteger() routine.
	TclParseNumber covers the task just fine.

2006-09-19  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclEvent.c (Tcl_VwaitObjCmd): Rewrite so that an exceeded
	limit trapped in a vwait cannot cause a dangerous dangling trace.

2006-09-19  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c (INST_EXPON):	Native type overflow detection
	* tests/expr.test:	was completely broken.  Falling back on use of
	bignums for all non-trivial ** calculations until
	native-type-constrained special cases can be done carefully and
	correctly.  [Bug 1561260].

2006-09-15  Jeff Hobbs  <jeffh@ActiveState.com>

	* library/http/http.tcl:      Change " " -> "+" url encoding mapping
	* library/http/pkgIndex.tcl:  to " " -> "%20" as per RFC 3986.
	* tests/http.test (http-5.1): bump http to 2.5.3
	* unix/Makefile.in:
	* win/Makefile.in:

2006-09-12  Andreas Kupries  <andreask@activestate.com>

	* unix/configure.in (HAVE_MTSAFE_GETHOST*): Modified to recognize
	  HP-UX 11.00 and beyond as having mt-safe implementations of the
	  gethost functions.
	* unix/configure: Regenerated, using autoconf 2.59

	* unix/tclUnixCompat.c (PadBuffer): Fixed bug in calculation of
	  the increment needed to align the pointer, and added
	  documentation explaining why the macro is implemented as it is.

2006-09-11  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/rules.vc:    Updated to install http, tcltest and msgcat as
	* win/makefile.vc: Tcl Modules (as per Makefile.in).
	* win/makefile.vc: Added tommath_(super)class headers.

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

	* unix/Makefile.in (install-libraries): Fixed typo tcltest 2.3.9 -> 2.3.0.

2006-09-11  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclUnixCompat.c: make compatLock static and only declare it when
	it will actually be used; #ifdef parts of TSD that are not always
	needed; adjust #ifdefs to cover all possible cases; fix whitespace.

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

	* tests/msgcat.test: Bumped version in auxiliary files as well.
	* doc/msgcat.n: 

2006-09-11  Kevin Kenny  <kennykb@acm.org>

	* unix/Makefile.in:	Bumped msgcat version to 1.4.2 to be
	* win/Makefile.in:	consistent with dgp's commits of 2006-09-10.
	
2006-09-11  Don Porter  <dgp@users.sourceforge.net>

	* library/msgcat/msgcat.tcl:	Removed some unneeded [uplevel]s.

2006-09-10  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c:		Corrected INST_EXPON flaw that treated
	* tests/expr.test:		$x**1 as $x**3.  [Bug 1555371]

	* doc/tcltest.n:		Bump to version tcltest 2.3.0 to account
	* library/tcltest/pkgIndex.tcl:	for new "-verbose line" feature.
	* library/tcltest/tcltest.tcl:
	* unix/Makefile.in:
	* win/Makefile.in:
	* win/makefile.bc:
	* win/makefile.vc:

	* library/msgcat/msgcat.tcl:	Bump to version msgcat 1.4.2 to account
	* library/msgcat/pkgIndex.tcl:	for modifications.

2006-09-10  Daniel Steffen  <das@users.sourceforge.net>

	* library/msgcat/msgcat.tcl (msgcat::Init): on Darwin, add fallback of
	* tests/msgcat.test:                        default msgcat locale to
	* unix/tclUnixInit.c (TclpSetVariables):    current CFLocale identifier
	if available (via private ::tcl::mac::locale global, set at interp init
	when on Mac OS X 10.3 or later with CoreFoundation).

	* library/tcltest/tcltest.tcl: add 'line' verbose level: prints source
	* doc/tcltest.n:               file line information of failing tests.

	* macosx/Tcl.xcodeproj/project.pbxproj: add new tclUnixCompat.c file;
	revise tests target to use new tcltest 'line' verbose level.

	* unix/configure.in: add descriptions to new AC_DEFINEs for MT-safe.
	* unix/tcl.m4: add caching to new SC_TCL_* macros for MT-safe wrappers.
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

2006-09-08  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

	* unix/tclUnixCompat.c: Added fallback to gethostbyname()
	and gethostbyaddr() if the implementation is known to be
	MT-safe (currently for Darwin 6 or later only).

	* unix/configure.in: Assume gethostbyname() and gethostbyaddr()
	are MT-safe starting with Darwin 6 (Mac OSX 10.2).

	* unix/configure: Regenerated with autoconf V2.59

2006-09-08  Andreas Kupries  <andreask@activestate.com>

	* unix/tclUnixCompat.c: Fixed conditions for CopyArray/CopyString,
	  and CopyHostent. Also fixed bad var names in TclpGetHostByName.

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

	* unix/tclUnixCompat.c: Added fallback to MT-unsafe
	library calls if TCL_THREADS is not defined.
	Fixed alignment of arrays copied by CopyArrayi() to be
	on the sizeof(char *) boundary.

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

	* unix/tclUnixChan.c   Rewritten MT-safe wrappers to
	* unix/tclUnixCompat.c return ptrs to TSD storage
	* unix/tclUnixFCmd.c   making them all look like their
	* unix/tclUnixPort.h   MT-unsafe pendants API-wise.
	* unix/tclUnixSock.c   

2006-09-06  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

	* unix/tclUnixChan.c: Added TCL_THREADS ifdef'ed  usage
	* unix/tclUnixFCmd.c: of MT-safe calls like: 
	* unix/tclUnixSock.c: getpwuid, getpwnam, getgrgid, getgrnam,
	* unix/tclUnixPort.h: gethostbyname and gethostbyaddr.
	* unix/Makefile.in:   See Tcl Bug: 999544
	* unix/configure.in:
	* unix/tcl.m4:
	* unix/configure: Regenerated.

	* unix/tclUnixCompat.c: New file containing MT-safe implementation
	of some library calls.

2006-09-04  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Removed much complexity that is
	no longer needed.

	* tests/main.text (Tcl_Main-4.4):	Test corrected to not be
	timing sensitive to the Bug 1481986 fix. [Bug 1550858]

2006-09-04  Jeff Hobbs  <jeffh@ActiveState.com>

	* doc/package.n: correct package example

2006-08-31  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Corrected flawed logic for
	disabling the INST_TRY_CVT_TO_NUMERIC instruction at the end
	of an expression when function arguments contain operators.
	[Bug 1541274]

	* tests/expr-old.test:	The remaining failing tests reported in
	* tests/expr.test:	[Bug 1381715] are all new in Tcl 8.5, so
	there's really no issue of compatibility with Tcl 8.4 result to
	deal with.  Fixed by updating tests to expect 8.5 results.

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

	* generic/tclParseExpr.c:	Dropped the old expr parser.

2006-08-30  Jeff Hobbs  <jeffh@ActiveState.com>

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

	* win/tclWinChan.c [Bug 819667] Improve logic for identifying COM
	ports.

	* generic/tclIOGT.c (ExecuteCallback): 
	* generic/tclPkg.c (Tcl_PkgRequireEx): replace Tcl_GlobalEval(Obj)
	with more efficient Tcl_Eval(Obj)Ex

	* unix/Makefile.in (valgrindshell): add valgrindshell target and
	update default VALGRINDARGS.  User can override, or add to it with
	VALGRIND_OPTS env var.

	* generic/tclFileName.c (DoGlob): match incrs with decrs.

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

	* generic/tclParseExpr.c:	Use the "parent" field of
	orphan ExprNodes to store the closure of left pointers.  This
	lets us avoid repeated re-scanning leftward for the left
	boundary of subexpressions, which in worst case led to near
	O(N^2) runtime.

2006-08-29  Joe Mistachkin  <joe@mistachkin.com>

	* unix/tclUnixInit.c: Fixed the issue (typo) that was causing
	* unix/tclUnixThrd.c (TclpThreadGetStackSize): stack.test to
	fail on FreeBSD (and possibly other Unix platforms).

2006-08-29  Colin McCormack  <coldstore@users.sourceforge.net>

	* generic/tclIOUtil.c:  Added test for NULL return 
	* generic/tclPathObj.c: from Tcl_FSGetNormalizedPath
	* unix/tclUnixFile.c:   which was causing segv's per
	* win/tclWinFCmd.c:     Bug 1548263
	* win/tclWinFile.c:

2006-08-28  Kevin Kenny  <kennykb@acm.org>

	* library/tzdata/America/Havana:      Regenerated from Olson's
	* library/tzdata/America/Tegucigalpa: tzdata2006k.
	* library/tzdata/Asia/Gaza:
	
2006-08-28  Don Porter  <dgp@users.sourceforge.net>

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

	* generic/tclStringObj.c:	Corrected TclFormatObj's failure
	to count up the number of arguments required by examining the
	format string.  [Bug 1547681]

2006-08-27  Joe Mistachkin  <joe@mistachkin.com>

	* generic/tclClock.c (ClockClicksObjCmd): Fix nested macro breakage
	with TCL_MEM_DEBUG enabled. [Bug 1547662]

2006-08-26  Miguel Sofer  <msofer@users.sf.net>

	* doc/namespace.n:
	* generic/tclNamesp.c:
	* tests/upvar.test: bugfix, docs clarification and new tests for
	[namespace upvar] as follow up to [Bug 1546833], reported by Will
	Duquette. 

2006-08-24  Kevin Kenny  <kennykb@acm.org>

	* library/tzdata: Regenerated, including several new files,
	from Olson's tzdata2006j.
	* library/clock.tcl: 
	* tests/clock.test: Removed an early testing hack that allowed
	loading 'registry' from the build tree rather than an installed
	one.  This is a workaround for [Bug 15232730], which remains open
	because it's a symptom of a deeper underlying problem.

2006-08-23  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclParseExpr.c:	Minimal collection of new tests
	* tests/parseExpr.test:		testing the error messages of the
	new expr parser.  Several bug fixes and code simplifications that
	appeared during that effort.

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

	* generic/tclIOUtil.c:	Revisions to complete the thread finalization
	of the cwdPathPtr.  [Bug 1536142]

	* generic/tclParseExpr.c:	Revised mistaken call to
	TclCheckBadOctal(), so both [expr 08] and [expr 08z] have same
	additional info in error message.

	* tests/compExpr-old.test:	Update existing tests to not fail
	* tests/compExpr.test:		with the new expr parser.
	* tests/compile.test:
	* tests/expr-old.test:
	* tests/expr.test:
	* tests/for.test:
	* tests/if.test:
	* tests/parseExpr.test:
	* tests/while.test:

2006-08-21  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* win/Makefile.in (gdb): Make this target work so that debugging an
	msys build is possible.

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

	* macosx/tclMacOSXNotify.c (Tcl_WaitForEvent): if the run loop is
	already running (e.g. if Tcl_WaitForEvent was called recursively),
	re-run it in a custom run loop mode containing only the source for the
	notifier thread, otherwise wakeups from other sources added to the
	common run loop modes might get lost.

	* unix/tclUnixNotfy.c (Tcl_WaitForEvent): on 64-bit Darwin,
	pthread_cond_timedwait() appears to have a bug that causes it to wait
	forever when passed an absolute time which has already been exceeded by
	the system time; as a workaround, when given a very brief timeout, just
	do a poll on that platform. [Bug 1457797]

	* generic/tclClock.c (ClockClicksObjCmd): add support for Darwin
	* generic/tclCmdMZ.c (Tcl_TimeObjCmd):    nanosecond resolution timer
	* generic/tclInt.h:                       to [clock clicks] and [time]
	* unix/configure.in (Darwin):             when TCL_WIDE_CLICKS defined.
	* unix/tclUnixTime.c (TclpGetWideClicks, TclpWideClicksToNanoseconds):
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

	* unix/tclUnixPort.h (Darwin): override potentially faulty configure
	detection of termios availability in all cases, since termios is known
	to be present on all Mac OS X releases since 10.0. [Bug 497147]

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

	* unix/tcl.m4 (Darwin): add support for --enable-64bit on x86_64, for
	universal builds including x86_64, for 64-bit CoreFoundation on Leopard
	and for use of -mmacosx-version-min instead of MACOSX_DEPLOYMENT_TARGET
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

	* generic/tcl.h:          add fixes for building on Leopard and support
	* unix/tclUnixPort.h:     for 64-bit CoreFoundation on Leopard.
	* macosx/tclMacOSXFCmd.c:

	* unix/tclUnixPort.h: on Darwin x86_64, disable use of vfork as it
	causes execve to fail intermittently. (rdar://4685553)

	* generic/tclTomMath.h: on Darwin 64-bit, for now disable use of
	128-bit arithmetic through __attribute__ ((mode(TI))), as it leads to
	link errors due to missing fallbacks. (rdar://4685527)

	* macosx/Tcl.xcodeproj/project.pbxproj: add x86_64 to universal build,
	switch native release targets to use DWARF with dSYM, Xcode 3.0 changes
	* macosx/README: updates for x86_64 and Xcode 2.4.

	* macosx/Tcl.xcodeproj/default.pbxuser: add test suite target that runs
	* macosx/Tcl.xcodeproj/project.pbxproj: the tcl test suite at build
	time and shows clickable test suite errors in the GUI build window.

	* tests/macOSXFCmd.test: fix use of deprecated resource fork paths.

	* unix/tclUnixInit.c (TclpInitLibraryPath): move code that is only
	needed when TCL_LIBRARY is defined to run only in that case.

	* generic/tclLink.c (LinkTraceProc): fix 64-bit signed-with-unsigned
	comparison warning from gcc4 -Wextra.

	* unix/tclUnixChan.c (TclUnixWaitForFile): with timeout < 0, if
	select() returns early (e.g. due to a signal), call it again instead of
	returning a timeout result. Fixes intermittent event-13.8 failures.

2006-08-17  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompile.c:		Revised the new set of expression parse
	* generic/tclParseExpr.c:	error messages.

2006-08-16  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclParseExpr.c:	Replace PrecedenceOf() function with
	prec[] static array.

2006-08-14  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* library/clock.tcl (::tcl::clock::add): Added missing braces to
	clockval validation code. Pointed out on comp.lang.tcl.

2006-08-11  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclNamesp.c: Improvements in buffer management to make
	namespace creation faster. Plus selected other minor improvements to
	code quality. [Patch 1352382]

2006-08-10  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	Misc patches to make code more efficient. [Bug 1530474] (afredd)
	* generic/*.c, macosx/tclMacOSXNotify.c, unix/tclUnixNotfy.c,
	* win/tclWinThrd.c: Tidy up invokations of Tcl_Panic() to promote
	string constant sharing and consistent style.
	* generic/tclBasic.c (Tcl_CreateInterp): More efficient handling of
	* generic/tclClock.c (TclClockInit):     registration of commands not
						 in global namespace.
	* generic/tclVar.c (Tcl_UnsetObjCmd): Remove unreachable clause.

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

        * generic/tclEncoding.c:        Replace buffer copy in for loop
        with call to memcpy().  Thanks to afredd. [Patch 1530262]

2006-08-09  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCmdIL.c (Tcl_LassignObjCmd): Make the wrong#args message a
	bit more consistent with those used elsewhere. [Bug 1534628]

	* generic/tclDictObj.c (DictForCmd): Stop crash when attempting to
	iterate over an invalid dictionary. [Bug 1531184]

	* doc/ParseCmd.3, doc/expr.n, doc/set.n, doc/subst.n, doc/switch.n:
	* doc/tclvars.n: Ensure that uses of [expr] in documentation examples
	are also good style (with braces) unless otherwise necessary. [Bug
	1526581]

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

	* unix/tclUnixPipe.c (TclpCreateProcess): for USE_VFORK: ensure
	standard channels are initialized before vfork() so that the child
	doesn't potentially corrupt global state in the parent's address space.

	* tests/compExpr-old.test: add 'oldExprParser' constraint to all tests
	* tests/compExpr.test:     that depend on the exact format of the error
	* tests/compile.test:      messages of the pre-2006-07-05 expression
	* tests/expr-old.test:     parser. The constraint is on by default (i.e
	* tests/expr.test:         those tests still fail), but can be turned
	* tests/for.test:          off by passing '-constraints newExprParser'
	* tests/if.test:           to tcltest, which will skip the 196 failing
	* tests/parseExpr.test:    tests in the testsuite that are caused by
	* tests/while.test:        the new expression parser error messages.

2006-07-31  Kevin Kenny  <kennykb@acm.org>

	* generic/tclClock.c (ConvertLocalToUTCUsingC): Corrected a regression
	that caused dates before 1969 to be one day off in the :localtime time
	zone if TZ is not set. [Bug 1531530]

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

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

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

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

2006-07-26  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c:	Corrected flawed overflow detection in
	* tests/expr.test:	INST_EXPON that caused [expr 2**64] to return 0
	instead of the same value as [expr 1<<64].

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

	* win/tclWinSock.c:	Correct un-initialized Tcl_DString. Thanks to
	afredd. [Bug 1518166]

2006-07-21  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c:
	* tests/execute.test (execute-9.1): dgp's fix for [Bug 1522803].

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

	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier, Tcl_WaitForEvent): create
	notifier thread lazily upon first call to Tcl_WaitForEvent() rather
	than in Tcl_InitNotifier(). Allows calling exeve() in processes where
	the event loop has not yet been run (Darwin's execve() fails in
	processes with more than one thread), in particular allows embedders to
	call fork() followed by execve(), previously the pthread_atfork() child
	handler's call to Tcl_InitNotifier() would immediately recreate the
	notifier thread in the child after a fork.

	* macosx/tclMacOSXFCmd.c (TclMacOSXCopyFileAttributes):    add support
	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier):             for weakly
	* unix/tclUnixInit.c (Tcl_GetEncodingNameFromEnvironment): importing
	symbols not available on OSX 10.2 or 10.3, enables binaires built on
	later OSX versions to run on earlier ones.
	* macosx/Tcl.xcodeproj/project.pbxproj: enable weak-linking; turn on
	                                        extra warnings.
	* macosx/README: document how to enable weak-linking; cleanup.
	* unix/tclUnixPort.h: add support for weak-linking; conditionalize
	AvailabilityMacros.h inclusion; only disable realpath on 10.2 or earlier
	when threads are enabled.
	* unix/tclLoadDyld.c (TclpLoadMemoryGetBuffer): change runtime Darwin
	* unix/tclUnixInit.c (TclpInitPlatform):        release check to use
	                                                global initialized once.
	* unix/tclUnixFCmd.c (DoRenameFile, TclpObjNormalizePath): add runtime
	Darwin release check to determine if realpath is threadsafe.
	* unix/configure.in: add check on Darwin for compiler support of weak
	* unix/tcl.m4:       import and for AvailabilityMacros.h header;
	move Darwin specific checks & defines that are only relevant to the tcl
	build out of tcl.m4; restrict framework option to Darwin; cleanup
	quoting and help messages.
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

	* generic/regc_locale.c (cclass):
	* generic/tclExecute.c (TclExecuteByteCode):
	* generic/tclIOCmd.c (Tcl_ExecObjCmd):
	* generic/tclListObj.c (NewListIntRep):
	* generic/tclObj.c (Tcl_GetLongFromObj, Tcl_GetWideIntFromObj,
	                    FreeBignum, Tcl_SetBignumObj):
	* generic/tclParseExpr.c (Tcl_ParseExpr):
	* generic/tclStrToD.c (TclParseNumber):
	* generic/tclStringObj.c (TclAppendFormattedObjs):
	* unix/tclLoadDyld.c (TclpLoadMemory):
	* unix/tclUnixPipe.c (TclpCreateProcess): fix signed-with-unsigned
	comparison and other warnings from gcc4 -Wextra.

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

	* unix/tclUnixPort.h: Added the inclusion of <AvailabilityMacros.h>.
	The missing header caused the upcoming #if conditions to wrongly
	exclude realpath, causing file normalize to ignore symbolic links in
	the path.

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

	* generic/tclAsync.c: Made Tcl_AsyncDelete() more tolerant when called
	after all thread TSD has been garbage-collected.

2006-07-05  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclParseExpr.c:	Completely new expression parser that
	builds a parse tree instead of operating with deep recursion. This
	corrects reports of stack-blowing crashes parsing long expressions [Bug
	906201] and replaces a fundamentally O(N^2) algorithm with an O(N) one
	[RFE 903765]. The new parser is better able to generate error messages
	that clearly report both the nature and context of the syntax error
	[Bugs 1029267, 1381715]. For now, the code for the old parser is still
	present and can be activated with a "#define OLD_EXPR_PARSER 1". This
	is for the sake of a clean implementation patch, and for ease of
	benchmarking. The new parser is non-recursive, so much lighter in stack
	consumption, but it does use more heap, so there may be cases where
	parsing of long expressions that succeeded with the old parser will
	lead to out of memory panics with the new one. There are still more
	improvements possible on that point, though significant progress may
	require changes to the Tcl_Token specifications documented for the
	public Tcl_Parse*() routines.
	***POTENTIAL INCOMPATIBILITY*** for any callers that rely on the exact
	(usually terrible) error messages generated by the old parser. This
	includes a large number of tests in the test suite.

	* generic/tclInt.h:		Replaced TclParseWhiteSpace() with
	* generic/tclParse.c:		TclParseAllWhiteSpace() which is what
	* generic/tclParseExpr.c:	all the callers really needed. Breaking
	whitespace runs at newlines is useful only to the command parsing
	function, and it can call the file scoped routine ParseWhiteSpace() to
	do that.

	* tests/expr-old.test:	Removed knownBug constraints that masked
	* tests/expr.test:	failures due to revised error messages.
	* tests/parseExpr.test:

2006-06-20  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclIOUtil.c:	Changed default configuration to
	* generic/tclInt.decls:	#undef USE_OBSOLETE_FS_HOOKS which disables
	* generic/tclTest.c:	access to the Tcl 8.3 internal routines for
	hooking into filesystem operations. Everyone ought to have migrated to
	Tcl_Filesystems by now.
	***POTENTIAL INCOMPATIBILITY*** for any code still stuck in the
	pre-Tcl_Filesystem era.

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

	* generic/tclStrToD.c:	Removed dead code that permitted disabling of
	recognition of the new 0b and 0o numeric formats.

	* generic/tclExecute.c:	Removed dead code that implemented alternative
	* generic/tclObj.c:	design where numeric values did not
	automatically narrow to the smallest Tcl_ObjType required to hold them.

	* generic/tclCmdAH.c:	Removed dead code that was old implementation
	of [format].

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

	* unix/tclUnixPort.h (Darwin): support for MAC_OS_X_VERSION_MAX_ALLOWED
	define from AvailabilityMacros.h: override configure detection and only
	use API available in the indicated OS version or earlier.

2006-06-14  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* doc/format.n, doc/scan.n: Added examples for converting between
	characters and their numeric interpretations following user prompting.

2006-06-13  Donal K. Fellows  <dkf@users.sf.net>

	* unix/tclLoadDl.c (TclpDlopen): Workaround for a compiler bug in Sun
	Forte 6. [Bug 1503729]

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

	* doc/GetStdChan.3:	Added recommendation that each call to
	Tcl_SetStdChannel() be accompanied by a call to Tcl_RegisterChannel().

2006-06-05  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* doc/Alloc.3: Added documentation of promise that Tcl_Realloc(NULL,x)
	is the same as Tcl_Alloc(x), as discussed in comp.lang.tcl. Also fixed
	nonsense sentence to say something meaningful.

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

	* generic/tcl.h (Tcl_DecrRefCount): use if/else construct to allow
	placement in unbraced outer if/else conditions. (jcw)

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

	* macosx/tclMacOSXNotify.c: implemented pthread_atfork() handler that
	* unix/tcl.m4 (Darwin):     recreates CoreFoundation state and notifier
	thread in the child after a fork(). Note that pthread_atfork is
	available starting with Tiger only. Because vfork() is used by the core
	on Darwin, [exec]/[open] are not affected by this fix, only extensions
	or embedders that call fork() directly (such as TclX). However, this
	only makes fork() safe from corefoundation tcl with --disable-threads;
	as on all platforms, forked children may deadlock in threaded tcl due
	to the potential for stale locked mutexes in the child. [Patch 923072]

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

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

	* unix/tcl.m4 (SC_CONFIG_SYSTEM): Fixed quoting of command script to
	awk; it was a rarely used branch, but it was wrong. [Bug 1494160]

2006-05-23  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* doc/chan.n, doc/refchan.n: Tighten up the documentation to follow a
	slightly more consistent style with regard to argument capitalization.

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

	* generic/tclProc.c (ProcCompileProc): When a bump of the compile epoch
	forces the re-compile of a proc body, take care not to overwrite any
	Proc struct that may be referred to on the active call stack. This
	fixes [Bug 1482718]. Note that the fix will not be effective for code
	that calls the private routine TclProcCompileProc() directly.

2006-05-13  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclEvent.c (HandleBgErrors): fix leak. [Coverity issue 86]

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

	* generic/tclMain.c (Tcl_Main):		Corrected flaw that required
	* tests/main.test: (Tcl_Main-4.5):	processing of one interactive
	command before passing control to the loop routine registered with
	Tcl_SetMainLoop() [Bug 1481986].

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

	* tests/scan.test:	decimal formatted integers. Fixed to match.

2006-04-19  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclStrToD.c: Added code to support the "middle endian"
	floating point format used in the Nokia N770's software-based floating
	point. Thanks to Bruce Johnson for reporting this bug, originally on
	http://wiki.tcl.tk/15408.
	* library/clock.tcl: Fixed a bug with Daylight Saving Time and Posix
	time zone specifiers reported by Martin Lemburg in
	http://groups.google.com/group/comp.lang.tcl/browse_thread/thread/9a8b15a4dfc0b7a0
	(and not at SourceForge).
	* tests/clock.test: Added test case for the above bug.

2006-04-18  Donal K. Fellows  <dkf@users.sf.net>

	* doc/IntObj.3: Minor review fixes, including better documentation of
	the behaviour of Tcl_GetBignumAndClearObj.

2006-04-17  Don Porter  <dgp@users.sourceforge.net>

	* doc/IntObj.3:	Documentation changes to account for TIP 237 changes.
	* doc/Object.3:	[Bug 1446971]

2006-04-12  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/regc_locale.c (cclass): Redefined the meaning of [:print:] to
	be exactly UNICODE letters, numbers, punctuation, symbols and spaces
	(*not* whitespace). [Bug 1376892]

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

	* generic/tclTrace.c:   Stop some interference between enter traces
	* tests/trace.test:     and enterstep traces. [Bug 1458266]

	* generic/tclPathObj.c:	Yet another revised fix for the [Bug 1379287]
	* tests/fileSystem.test:	family of path normalization bugs.

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

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

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

	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct):	It seems there
	* tests/indexObj.test:	are extensions that rely on the prior behavior
	* doc/GetIndex.3:	that the empty string cannot succeed as a
	unique prefix matcher, so I'm restoring Donal Fellows's solution. Added
	mention of this detail to the documentation. [Bug 1464039]

	* tests/compExpr-old.test:	Updated testmathfunctions constraint
	* tests/compExpr.test:		to post-TIP-232 world.
	* tests/expr-old.test:
	* tests/expr.test:
	* tests/info.test:

	* tests/indexObj.test:	Corrected other test errors revealed by
	* tests/upvar.test:	testing outside the tcltest application.

	* generic/tclPathObj.c: Revised fix for the [Bug 1379287] family of
	path normalization bugs.

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

	* unix/tcl.m4: removed TCL_IO_TRACK_OS_FOR_DRIVER_WITH_BAD_BLOCKING
	define on Darwin. [Bug 1457515]
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

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

	* win/tclWinInit.c:	More careful calls to Tcl_DStringSetLength()
	* win/tclWinSock.c:	to avoid creating invalid DString states.
	* win/tclWinDde.c:	Bump to version 1.3.2. [RFE 1366195]
	* library/dde/pkgIndex.tcl:

	* library/reg/pkgIndex.tcl:	Bump to registry 1.2 because
	* win/tclWinReg.c:	Registry_Unload() is a new public routine
	* win/Makefile.in:	compared to the 1.1.* releases.

	* win/configure.in:	Bump package version numbers.
	* win/configure:	autoconf 2.59

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

	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct): Allow empty
	strings to be matched by the Tcl_GetIndexFromObj machinery, in the
	same manner as any other key. [Bug 1464039]

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

	* generic/tclIO.c (ReadChars): Added check, panic and commentary to a
	piece of code which relies on BUFFER_PADDING to create enough space at
	the beginning of each buffer for the insertion of partial multibyte
	data at the beginning of a buffer. Commentary explains why this code is
	OK, and the panic is as a precaution if someone twiddled the
	BUFFER_PADDING into uselessness.

	* generic/tclIO.c (ReadChars): [Bug 1462248]. Temporarily suppress the
	use of TCL_ENCODING_END set when EOF was reached while the buffer we
	are converting is not truly the last buffer in the queue. Together with
	the Utf bug below it was possible to completely wreck the buffer data
	structures, eventually crashing Tcl.

	* generic/tclEncoding.c (UtfToUtfProc): Stop accessing memory beyond
	the end of the input buffer when TCL_ENCODING_END is set and the last
	bytes of the buffer start a multi-byte sequence. This bug contributed
	to [Bug 1462248].

2006-03-30  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: remove unused var and silence gcc warning

	* generic/tclPathObj.c:	 More fixes for path normalization when /../
	* tests/fileSystem.test: tries to go beyond root.[Bug 1379287]

	* generic/tclExecute.c: Revised INST_MOD implementation to do
	calculations in native types as much as possible, moving to mp_ints
	only when necessary.

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

	* win/tclWinPipe.c (TclpCreateProcess): change panics to Tcl errors and
	do proper refcounting of noe objPtr. [bug 1194429]

	* unix/tcl.m4, win/tcl.m4: []-quote AC_DEFUN functions.

	* macosx/Tcl.xcodeproj/project.pbxproj: TCL_PACKAGE_PATH as per change
	to unix/configure.in of 2006-03-13.

	* unix/tclUnixFCmd.c (TclpObjNormalizePath): deal with *BSD/Darwin
	realpath() converting relative paths into absolute paths. [Bug 1064247]

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

	* generic/tclIOUtil.c: fix to nativeFilesystemRecord comparisons
	(lesser part of [Bug 1064247])

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

2006-03-27  Andreas Kupries <andreask@activestate.com>

	* doc/CrtChannel.3:    Added TCL_CHANNEL_VERSION_5, made it the version
	* generic/tcl.h:       where the "truncateProc" is defined at, and
	* generic/tclIO.c:     moved all channel drivers of Tcl to v5.
	* generic/tclIOGT.c, generic/tclIORChan.c, unix/tclUnixChan.c:
	* unix/tclUnixPipe.c, win/tclWinChan.c, win/tclWinConsole.c:
	* win/tclWinPipe.c, win/tclWinSerial.c, win/tclWinSock.c:

2006-03-27  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c: Merge INST_MOD computation in with the
	INST_?SHIFT instructions, which also operate only on two integral
	values. Also corrected flaw that made INST_BITNOT of wide values
	require mp_int calculations. Also corrected type that missed optimized
	handling of the tclBooleanType by the TclGetBooleanFromObj macro.

	* changes:	Updates for another RC.

2006-03-25  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c: Corrections to INST_EXPON detection of overflow
	to use mp_int calculations.

2006-03-24  Kevin Kenny  <kennykb@acm.org>

	* generic/tclExecute.c (TclExecuteByteCode): Added a couple of missing
	casts to 'int' that were affecting compilablity on VC6.

2006-03-24  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclEncoding.c: Reverted latest change [Bug 506653] since it
	reportedly killed test performance on Windows.

	* generic/tclExecute.c: Revised INST_EXPON implementation to do
	calculations in native types as much as possible, moving to mp_ints
	only when necessary.

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

	* generic/tclExecute.c: Merged INST_EXPON handling in with the other
	binary operators that operate on all number types (INST_ADD, etc.).

	* tests/env.test: With case preserved (see 2006-03-21 commit) be sure
	to do case-insensitive filtering. [Bug 1457065]

2006-03-23  Reinhard Max  <max@suse.de>

	* unix/tcl.spec: Cleaned up and completed the spec file. An RPM can now
	be built from the tcl source distribution with "rpmbuild -tb <tarball>"

2006-03-22  Reinhard Max  <max@suse.de>

	* tests/stack.test: Run the stack tests in subshells, so that they are
	reported as failed tests rather than bugs in the test suite if the
	recursion causes a segfault.

2006-03-21  Don Porter  <dgp@users.sourceforge.net>

	* changes:	Updates for another RC.

	* generic/tclStrToD.c:	One of the branches of AccumulateDecimalDigit

	* macosx/tclMacOSXFCmd.c:codes and 'hidden' flag, as documented in
	* tests/macOSXFCmd.test: glob.n; objectified OSType handling in [glob]
	* unix/tclUnixFile.c:    and [file attributes]; fix globbing for

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

2006-03-20  Andreas Kupries <andreask@activestate.com>

	* win/Makefile.in (install-libraries): Generate tcl8/8.4 directory
	under Windows as well (cygwin Makefile). Related entry: 2006-03-07,
	dgp. This moved the installation of http from 8.2 to 8.4, partially. A
	fix of the required directory creation was done for unix on Mar 10,
	without entry in the Changelog. This entry is for the fix of the
	directory creation under Windows.

	* unix/installManPage: There is always one even more broken "sed".
	Moved the # comment starting character in the sed script to the
	beginning of their respective lines. The AIX sed will not recognize
	them as comments otherwise :( The actual text stays indented for better
	association with the commands they belong to.

2006-03-20  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* tests/cmdAH.test, tests/fCmd.test, tests/unixFCmd.test:
	* tests/winFCmd.test: Cleanup of some test constraint handling, and a
	few other minor issues.

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

	* generic/tclFileName.c:
	* doc/FileSystem.3:
	* tests/fileName.test: Fix to [Bug 1084705] so that 'glob -nocomplain'
	finally agrees with its documentation and doesn't swallow genuine
	errors.

	***POTENTIAL INCOMPATIBILITY*** for scripts that assumed '-nocomplain'
	removes the need for 'catch' to deal with non-understood path names.

	Small optimisation to implementation of pattern==NULL case of TclGlob,
	and clarification to the documentation. [Tclvfs bug 1405317]

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

	* tests/fCmd.test: added knownBug test case for [Bug 1394972]

	* tests/winFCmd.test:
	* tests/tcltest.test: corrected tests to better account for behaviour
	of writable/non-writable directories on Windows 2000/XP. This, with the
	previous patches, closes [Bug 1193497]

2006-03-17  Andreas Kupries <andreask@activestate.com>

	* doc/chan.n: Updated with documentation for the commands 'chan create'
	and 'chan postevent' (TIP #219).

	* doc/refchan.n: New file. Documentation of the command handler API for
	reflected channels (TIP #219).

2006-03-17  Joe Mistachkin <joe@mistachkin.com>

	* unix/tclUnixPort.h: Include pthread.h prior to pthread_np.h [Bug
	1444692]

	* win/tclWinTest.c: Corrected typo of 'initializeMutex' that prevented
	successful compilation.

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

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

	* tests/io.test (io-43.1 io-44.[1234]): Rewritten to be self-contained
	with regard to setup and cleanup. [Bug 681793].

	* generic/tclIOUtil.c (TclGetOpenMode): Added the flag O_APPEND to the
	list of POSIX modes used when opening a file for 'a'ppend. This
	enables the proper automatic seek-to-end-on-write by the OS. See [Bug
	680143] for longer discussion.

	* tests/ioCmd.test (iocmd-13.7.*): Extended the testsuite to check the
	new handling of 'a'.

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

	* tests/socket.test: Extended the timeout in socket-11.11 from 10 to 40
	seconds to allow for really slow machines. Also extended
	actual/expected results with value of variable 'done' to make it
	clearer when a test fails due to a timeout. [Bug 792159].

2006-03-15  Vince Darley  <vincentdarley@sourceforge.net>

	* win/fCmd.test: add proper test constraints so the new tests don't run
	on Unix.

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

	* generic/tclPipe.c (TclCreatePipeline): Modified the processing of
	pipebars to fail if the last bar is followed only by redirections. [Bug
	768659]

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

	* doc/fconfigure.n: Clarified that -translation is binary is reported
	as lf when queried, because it is identical to lf, except for the
	special additional behaviour when setting it. [Bug 666770].

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

	* doc/clock.n: Removed double-quotes around section title NAME; not
	needed.
	* unix/installManpage: Reverted part to handle double-quotes in section
	NAME, chokes older sed installations.

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

	* library/tm.tcl (::tcl::tm::Defaults): Fixed handling of environment
	variable TCLX.y_TM_PATH, bad variable reference. [Bug 1448251]. Thanks
	to Julian Noble.

2006-03-14  Vince Darley  <vincentdarley@sourceforge.net>

	* win/tclWinFile.c: updated patch to deal with 'file writable' issues
	on Windows XP/2000.
	* generic/tclTest.c:
	* unix/tclUnixTest.c:
	* win/tclWinTest.c:
	* tests/fCmd.test: updated test suite to deal with correct permissions
	setting and differences between XP/2000 and 95/98 3 tests still fail;
	to be dealt with shortly

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

	* generic/tclEncoding.c: Report error when an escape encoding is
	missing one of its sub-encodings [Bug 506653].

	* unix/configure.in:    Revert change from 2005-07-26 that sometimes
	* unix/configure:       added $prefix/share to the tcl_pkgPath. See
	[Patch 1231015]. autoconf-2.59.

2006-03-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclProc.c (ObjInterpProcEx):
	* tests/apply.test (apply-5.1): Fix [apply] error messages so that they
	quote the lambda expression [Bug 1447355].

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

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

	* generic/tclEvent.c: Cosmetic touches and identation
	* generic/tclInt.h: Added TclpFinalizeSockets() call.

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

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

	* win/tclWinPipe.c, win/tclWinSock.c: Finalization of sockets/pipes is
	now solely done in TclpFinalizeSockets() and TclpFinalizePipes() and
	not over the thread-exit handler, because the order of actions the Tcl
	generic core will impose may result in cores/hangs if the thread exit
	handler tears down corresponding subsystem(s) too early.

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

	* win/tclWinFile.c: previous patch breaks tests, so removed.

2006-03-09  Vince Darley  <vincentdarley@sourceforge.net>

	* win/tclWinFile.c: fix to 'file writable' in certain XP directories.
	Thanks to fvogel and jfg. [Patch 1344540] Modified patch to make use of
	existing use of getSecurityProc.

2006-03-08  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c:	Complete missing bit of TIP 215 implementation
	* tests/incr.test:

2006-03-07  Joe English  <jenglish@users.sourceforge.net>

	* unix/tcl.m4: Set SHLIB_LD_FLAGS='${LIBS}' on NetBSD, as per the other
	*BSD variants [Bug 1334613].
	* unix/configure: Regenerated.

2006-03-07  Don Porter  <dgp@users.sourceforge.net>

	* changes:	Update in prep. for 8.5a4 release.

	* unix/Makefile.in:	Package http 2.5.2 requires Tcl 8.4, so the
	* win/Makefile.in:	*.tm installation has to be placed in an "8.4"
	directory, not an "8.2" directory.

2006-03-06  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:   Revised handling of TCL_EVAL_* flags to
	* tests/parse.test:     simplify TclEvalObjvInternal and to correct the
	auto-loading of alias targets (parse-8.12). [Bug 1444291]

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

	* generic/tclPathObj.c: Revised yesterday's fix for [Bug 1379287] to
	work on Windows.

	* generic/tclObj.c:	Compatibility support for existing code that
	calls Tcl_GetObjType("boolean").

2006-03-02  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclPathObj.c:		Fix for failed normalization of paths
	* tests/fileSystem.test:	with /../ that lead back to the root of
	the filesystem, like /foo/.. [Bug 1379287]

2006-03-01  Reinhard Max  <max@suse.de>

	* unix/installManPage: Fix the script for manpages that have quotes
	around the .SH arguments, as doctools produces them [Bug 1292145]. Some
	minor cleanups and improvements.

2006-02-28  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Corrections to be sure that TCL_EVAL_GLOBAL
	* tests/namespace.test:	evaluations act the same as [uplevel #0]
	* tests/parse.test:	evaluations, even when execution traces or
	* tests/trace.test:	invocations of [::unknown] are present.
	[Bug 1439836].

2006-02-22  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Corrected a few bugs in how [namespace
	* tests/namespace.test:	unknown] interacts with TCL_EVAL_* flags.
	[Patch 958222]

2006-02-17  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclIORChan.c:	Revised error message generation and handling
	* tests/ioCmd.test:	of exceptional return codes in the channel
	reflection layer. [Bug 1372348]

2006-02-16  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclIndexObj.c:	Disallow the "ambiguous" error message
	* tests/indexObj.test:		when TCL_EXACT matching is requested.
	* tests/ioCmd.test:

2006-02-15  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclIO.c:	Made several routines tolerant of
	* generic/tclIORChan.c:	interp == NULL arguments. [Bug 1380662]
	* generic/tclIOUtil.c:

2006-02-09  Don Porter  <dgp@users.sourceforge.net>

	TIP#215 IMPLEMENTATION

	* doc/incr.n:		Revised [incr] to auto-initialize when varName
	* generic/tclExecute.c:	argument is unset. [Patch 1413115].
	* generic/tclVar.c:
	* tests/compile.test:
	* tests/incr-old.test:
	* tests/incr.test:
	* tests/set.test:

	* tests/main.test (Tcl_Main-6.7):	Improved robustness of
	command auto-completion test. [Bug 1422736].

2006-02-08  Donal K. Fellows  <dkf@users.sf.net>

	* doc/Encoding.3, doc/encoding.n: Updates due to review at request of
	Don Porter. Mostly minor changes.

2006-02-08  Don Porter  <dgp@users.sourceforge.net>

	TIP#258 IMPLEMENTATION

	* doc/Encoding.3:	New subcommand [encoding dirs].
	* doc/encoding.n:	New routine Tcl_GetEncodingNameFromEnvironment
	* generic/tcl.decls:	Made public:
	* generic/tclBasic.c:	TclGetEncodingFromObj
	* generic/tclCmdAH.c:		-> Tcl_GetEncodingFromObj
	* generic/tclEncoding.c:TclGetEncodingSearchPath
	* generic/tclInt.decls:		-> Tcl_GetEncodingSearchPath
	* generic/tclInt.h:	TclSetEncodingSearchPath
	* generic/tclTest.c:		-> Tcl_SetEncodingSearchPath
	* library/init.tcl:	Removed commands:
	* tests/cmdAH.test:		[tcl::unsupported::EncodingDirs]
	* tests/encoding.test:		[testencoding path] (Tcltest)
	* unix/tclUnixInit.c:	[Patch 1413934].
	* win/tclWinInit.c:

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

2006-02-01  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclProc.c: minor improvements to [apply]
	* tests/apply.test: new tests; apply-5.1 currently fails to indicate
	missing work in error reporting

2006-02-01  Don Porter  <dgp@users.sourceforge.net>

	TIP#194 IMPLEMENTATION

	* doc/apply.n:	(New file)	New command [apply]. [Patch 944803].
	* doc/uplevel.n:
	* generic/tclBasic.c:
	* generic/tclInt.h:
	* generic/tclProc.c:
	* tests/apply.test: (New file)
	* tests/proc-old.test:
	* tests/proc.test:

	TIP#181 IMPLEMENTATION

	* doc/namespace.n:	routines Tcl_(Get|Set)NamespaceUnknownHandler.
	* doc/unknown.n:	[Patch 958222].
	* generic/tcl.decls:
	* generic/tclBasic.c:
	* generic/tclInt.h:
	* generic/tclNamesp.c:
	* tests/namespace.test:

	* generic/tclDecls.h:	make genstubs

2006-01-26  Donal K. Fellows  <dkf@users.sf.net>

	* doc/dict.n: Fixed silly bug in example. Thanks to Heiner Marxen
	<heiner.marxen@unsel.de> for catching this! [Bug 1415725]

2006-01-26  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* unix/tclUnixChan.c (TclpOpenFileChannel): Tidy up and comment the
	mess to do with setting up serial channels. This (deliberately) breaks
	a broken FreeBSD port, indicates what we're really doing, and reduces
	the amount of conditional compilation sections for better maintenance.

2006-01-25  Donal K. Fellows  <dkf@users.sf.net>

	* unix/tclUnixInit.c (TclpInitPlatform): Improved conditions on when to
	update the FP rounding mode on FreeBSD, taken from FreeBSD port.

2006-01-23  Donal K. Fellows  <dkf@users.sf.net>

	* tests/string.test (string-12.21): Added test for [Bug 1410553] based
	on original bug report.

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

	* generic/tclStringObj.c: fixed incorrect handling of internal rep in
	Tcl_GetRange [Bug 1410553]. Thanks to twylite and Peter Spjuth.

	* generic/tclProc.c: fixed args handling for precompiled bodies [Bug
	1412695]; thanks to Uwe Traum.

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

	* generic/tclPipe.c (FileForRedirect): Prevent nameString from being
	freed without having been initialized.
	* tests/exec.test: Added a test for the above.

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

	* generic/tclPathObj.c (Tcl_FSGetInternalRep): backported patch from
	core-8-4-branch. A freed pointer has been overwritten causing all sorts
	of coredumps.

2006-01-12  Vince Darley  <vincentdarley@sourceforge.net>

	* win/tclWinFile.c: fix to sharing violation [Bug 1366227]

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

	* generic/tclBasic.c:	Moved Tcl_LogCommandInfo from tclBasic.c to
	* generic/tclNamesp.c:	tclNamesp.c to get access to identifier with
	* tests/error.test (error-7.0): file scope. Added check for traces on
	::errorInfo, and when present fall back to contruction of the stack
	trace in the variable so that write trace notification timings are
	compatible with earlier Tcl releases. This reduces, but does not
	completely eliminate the ***POTENTIAL INCOMPATIBILITY*** created by the
	2004-10-15 commit. [Bug 1397843].

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

	* unix/configure:    add caching, use AC_CACHE_CHECK instead of
	* unix/configure.in: AC_CACHE_VAL where possible, consistent message
	* unix/tcl.m4:       quoting, sync relevant tclconfig/tcl.m4 changes
	and gratuitous formatting differences, fix SC_CONFIG_MANPAGES with
	default argument, Darwin improvements to SC_LOAD_*CONFIG.

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

	* generic/tclNamesp.c (NamespaceInscopeCmd):    [namespace inscope]
	* tests/namespace.test: commands were not reported by [info level]
	[Bug 1400572].

2006-01-09  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclTrace.c: Stop exporting the guts of the trace command;
	nothing outside this file needs to see it. [Bug 971336]

2006-01-05  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* unix/tcl.m4 (TCL_CONFIG_SYSTEM): Factor out the code to determine
	the operating system version number, as it was replicated in several
	places.

2006-01-04  David Gravereaux  <davygrvy@pobox.com>

	* win/tclAppInit.c: WIN32 native console signal handler removed. This
	was found to be interfering with TWAPI extension one. IMO, special
	services such as signal handlers should best be done with extensions to
	the core after discussions on c.l.t. about Roy Terry's tclsh children
	of a real windows service shell.

2005-12-30  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclStubLib.c: Corrected a typo in "missing Stubs table
	pointer."

2005-12-27  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tcl.decls:  Destubbed TclTomMathInitializeStubs - it is in
	* generic/tcl.h:      the stub library, not the main shared
	* generic/tclBasic.c: library. Exported Tcl_InitBignumFromDouble.
	* generic/tclExecute.c:
	* generic/tclInt.h:
	* generic/tclStrToD.c:

	* generic/tclDecls.h:
	* generic/tclStubLib.c:
	* generic/tclStubInit.c: Regenerated.

	* generic/clock.tcl: Reverted to using the time zone abbreviation and
	not its name to "stop the bleeding" on [Bug 1386377]. This is *not* a
	good long-term solution, but there may not be one.

	* libtommath/bn_mp_sqrt.c: Improved the initial approximation to the
	square root, roughly doubling the speed of the routine. (This is a
	local change that needs to be communicated to Tom.)

	* win/Makefile.in: Corrected a bug where tommath_class.h and
	tommath_superclass.h were not installed, making it impossible for
	client code to compile against the tommath stubs.

	* library/tzdata: Updated to Olson's tzdata2005r. (Latest changes to
	Daylight Saving Time in Canada, plus redefinition of the Posix-style
	zones [e.g., EST5EDT] to be locale-independent.)

	* libtommath: Updated to Tom St.Denis's release 0.37.

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

	* generic/tclThreadAlloc.c (Tcl_GetMemoryInfo): Format values as longs
	and not ints, so they are less likely to wrap on 64-bit machines.

2005-12-19  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c:	Modified [string is double] to use
	* tests/string.test:	TclParseNumber() to parse trailing whitespace.
	Ensures consistency, and makes it easier to cleanup after invalid
	internal reps left behind by parsing [Bugs 1360532 1382287].

	* generic/tclParseExpr.c:	Added TCL_PARSE_NO_WHITESPACE to
	* generic/tclScan.c:	TclParseNumber() calls since [scan] and [expr]
	* tests/scan.test:	parsing don't want spaces in parsed numbers.

	* generic/tclInt.h:	Added TCL_PARSE_NO_WHITESPACE flag to the
	* generic/tclStrToD.c:	TclParseNumber() interface.

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

	* doc/Tcl.n: Clarify what is going on in variable substitution
	following thread on comp.lang.tcl.

2005-12-18  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCompCmds.c (TclCompileDictCmd): Ensure that we only do an
	'endCatch' when there's a preceding 'beginCatch'. [Bug 1382528] Many
	thanks to Anton Kovalenko for finding this and pointing out that it was
	a catch stack handling problem!

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

	* generic/tclIOUtil.c: workaround gcc warning "comparison is always
	* generic/tclTest.c:   false due to limited range of data type".

	* macosx/Tcl.xcode/project.pbxproj:
	* macosx/Tcl.xcodeproj/project.pbxproj:
	* unix/Makefile.in: add new tclTomMath* files.

	* generic/tclBasic.c: replace panic with Tcl_Panic.

2005-12-13  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tcl.decls:    Added changes to export an additional stubs
	* generic/tclBasic.c:   table to represent the 'libtommath' routines
	* generic/tclDecls.h:   that Tcl uses and export them to callers.
	* generic/tclInt.decls: Reran 'genstubs'
	* generic/tclInt.h:
	* generic/tclIntDecls.h:
	* generic/tclIntPlatDecls.h:
	* generic/tclStubInit.c:
	* generic/tclStubLib.c:

	* tools/fix_tommath_h.tcl:
	* unix/Makefile.in:
	* win/Makefile.in:
	* win/makefile.vc:

	* generic/tclClock.c:   Made changes to silence a number of compiler
	* generic/tclIO.c:	warnings when building with mingw.
	* generic/tclIORChan.c:
	* generic/tclLink.c:
	* generic/tclListObj.c:
	* generic/tclObj.c:

	* win/tclWinFCmd.c:
	* win/tclWinFile.c:
	* win/tclWinReg.c:
	* win/tclWinSock.c:

2005-12-13  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclExecute.c (TEBC:DICT_FIRST,DICT_DONE): Only decrease the
	references to the dictionary once the iteration completes. Do this by
	storing the dict in the iterator context variable. [Bug 1379349] Thanks
	to Ulrich Ring and Tobias Hippler for finding this.

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

	* unix/tcl.m4, unix/configure: Fix sh quoting error reported in
	bash-3.1+ [Bug 1377619] (schafer)

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

	* doc/mathfunc.n: Changed two examples from the incorrect 'tcl::math::'
	to 'tcl::mathfunc::' [Bug 1378818]

2005-12-09  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/configure: Regen.
	* win/tcl.m4 (SC_CONFIG_CFLAGS): Define MACHINE for gcc builds. The
	lack of a definition of this variable in the manifest file was causing
	a runtime error in wish built with gcc.

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

	* tests/lsearch.test (lsearch-10.8..10):  If the -start is off the end,
	* generic/tclCmdIL.c (Tcl_LsearchObjCmd): searching should find nothing
	at all. [Bug 1374778]

2005-12-08  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/Makefile.in, win/makefile.vc: Add Win x64 and CE build support
	* win/tcl.m4, win/configure:        CE still requires C code fixes.

	* generic/tcl.h: use struct __stat64 (not _stat64) for MSC_VER >= 1400
	(i.e. latest Platform SDK).

2005-12-07  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* doc/socket.n: Cross-referenced the socket documentation better to the
	fconfigure documentation on the topic of asynch sockets.
	* doc/fconfigure.n: Added keyword to documentation of -blocking option
	so that people looking for "asynch" can find it as well.

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

	* unix/tclUnixPort.h (Darwin): fix incorrect __DARWIN_UNIX03 configure
	overrides that were originally copied from Darwin CVS (rdar://3693001)

2005-12-05  Kevin B. Kenny  <kennykb@acm.org>

	* tools/tclZIC.tcl: Updated to reflect changes in calling sequence when
	GetJulianDateFromEraYearMonthDay moved to C.
	* library/tzdata: Regenerated from Olson's tzdata2005p.tar.gz - the
	'systemv' changes appear not to affect Tcl's processing of the dates.

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

	* unix/configure.in: move check for fts API to configure.in and run it
	* unix/tcl.m4:       on all platforms, since Linux glibc2 and *BSDs
	also have this; using fts is more efficient than a recursive
	opendir/readdir.
	* unix/tclUnixFCmd.c (TraverseUnixTree): add support to fts code for
	platforms with stat64.
	* unix/configure:
	* unix/tclConfig.h.in: regen.

2005-12-05  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/configure:     Use fts file API on Darwin if available.
	* unix/tcl.m4:        Addresses file delete issues in readdir noted
	* unix/tclUnixFCmd.c: in [Bug 1034337]. (steffen)
	Remove redundant stat call for each file in DoCopyFile. (steffen)

2005-12-02  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclClock.c: Moved a tiny bit more of [clock format] from run
	* library/clock.tcl: time to compile time, and fixed a l10n bug in the
	process. [Bug 1371446]. Also, conditoned the call to SetupTimeZone to
	speed the common case where TZData($timezone) already exists, and
	achieved a puny speedup by making ::tcl::clock::getenv not throw
	errors.
	* unix/Makefile.in: Made some changes to support a 'make' command that
	is present on some antiquated versions of Solaris.

2005-12-01  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl: Continued rationalizing the code, eliminating
	numerous redundant [mc] calls. Added another time boost by precompiling
	a [::format] command to do the bulk of the work of [clock format].

2005-12-01  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* unix/Makefile.in: Add remaining dependency info. While automated
	maintenance of this information would be good, having it at all is much
	better than a poke in the eye with a sharp stick...

2005-12-01  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclClock.c: fix warning.

	* unix/tcl.m4 (Darwin): fix error when MACOSX_DEPLOYMENT_TARGET unset
	* unix/configure: regen.

2005-11-30  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* unix/Makefile.in: Add dependency information relating to tclCompile.h
	since when the list of opcodes changes it is usually useful to rebuild
	everything that depends on it (but which is nonetheless a small
	fraction of the total set of Tcl source files).

	***POTENTIAL INCOMPATIBILITY*** for bytecode savers/loaders. See below

	* generic/tclCompCmds.c (TclCompileSwitchCmd): Arrange for very simple
	[switch] invokations to be compiled into hash lookups into jump tables;
	only a very specific kind of [switch] can be safely compiled this way,
	but that happens to be the most common kind. This makes around 5-10%
	difference to the speed of execution of clock.test.
	* generic/tclExecute.c (TEBC:INST_JUMP_TABLE): New instruction to allow
	for jumps to locations looked up in a hashtable. Requires a new AuxData
	type, tclJumptableInfoType (supported by the functions DupJumptableInfo
	and FreeJumptableInfo in tclCompCmds.c) so anything that saves bytecode
	containing this *must* be updated!

2005-11-30  Kevin Kenny  <kennykb@acm.org>

	* generic/tclClock.c: Fixed a bad refcount in previous commit that led
	to a corrupted heap. Also silenced a warning that some compilers gave
	about the excessively long constant for JULIAN_SEC_POSIX_EPOCH. Also
	fixed a bug where [clock format] would fail in the :localtime zone for
	times before the Posix Epoch. Thanks to Miguel Sofer for pointing out
	all of these. Also rationalized the code a little bit by moving parts
	of [clock scan] into C, eliminating some code that was duplicated in
	the C and Tcl layers.

2005-11-29  Kevin Kenny  <kennykb@acm.org>

	* generic/tclBasic.c:	Moved a big part of [clock format] down
	* generic/tclClock.c:   to the C level in order to make it go faster.
	* generic/tclInt.h:     Preliminary measurements suggest that it
	* generic/clock.tcl:    more than doubles in speed with this change.

2005-11-29  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCmdIL.c (Tcl_LsearchObjCmd): Allow [lsearch -regexp] to
	process REs that contain backreferences. This expensive mode of
	operation is only used if the RE would otherwise cause a compilation
	failure. [Bug 1366683]

2005-11-28  Kevin Kenny  <kennykb@acm.org>

	* tools/tclZIC.tcl (convertTimeOfDay): Corrected a typo that caused
	wrong DST transitions in any time zone where the transition is
	specified as local Standard Time (as opposed to wall-clock or UTC).
	(Also updated the code to be bignum-safe.)
	* tests/clock.test (clock-51.1): Added regression test for the above.
	* library/tzdata: Updated to Olson's 'tzdata2005o' (changes for Cuba,
	Nicaragua, Jordan, and Georgia) and regenerated. Thanks to Paul
	Mackerras for reporting this problem.

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

	* unix/tcl.m4 (Darwin): add 64bit support, check for Tiger copyfile(),
	add CFLAGS to SHLIB_LD to support passing -isysroot in env(CFLAGS) to
	configure (flag can't be present twice, so can't be in both CFLAGS and
	LDFLAGS during configure), don't use -prebind when deploying on 10.4,
	define TCL_IO_TRACK_OS_FOR_DRIVER_WITH_BAD_BLOCKING (rdar://3171542).
	(SC_ENABLE_LANGINFO, SC_TIME_HANDLER): add/fix caching, fix obsolete
	autoconf macros. Sync with tk/unix/tcl.m4.

	* unix/configure.in: fix obsolete autoconf macros, sync gratuitous
	formatting/ordering differences with tk/unix/configure.in.

	* unix/Makefile.in: add CFLAGS to tclsh/tcltest link to make executable
	linking the same as during configure (needed to avoid losing any linker
	relevant flags in CFLAGS, in particular flags that cannot be in
	LDFLAGS). Avoid concurrent linking of tclsh and compiling of
	tclTestInit.o or xtTestInit.o during parallel make.
	(checkstubs, checkdoc, checkexports): dependency and Darwin fixes
	(dist): add new macosx files.

	* unix/tclLoadDyld.c (TclpDlopen): use NSADDIMAGE_OPTION_WITH_SEARCHING
	on second NSAddImage only. [Bug 1204237]
	(TclGuessPackageName): should not be MODULE_SCOPE.
	(TclpLoadMemory): ppc64 and endian (i386) fixes, add support for
	loading universal (fat) bundles from memory.

	* unix/tclUnixFCmd.c:
	* macosx/tclMacOSXFCmd.c: ppc64 and endian (i386) fixes.
	(TclMacOSXCopyFileAttributes): add support for new Tiger copyfile() API
	to enable copying of xattrs & ACLs by [file copy].

	* generic/tcl.h: add Darwin specifc configure overrides for TCL_WIDE
	defines to support fat compiles of ppc and ppc64 at the same time,
	(replaces Darwin CVS fix by emoy, rdar://3693001). add/correct location
	of version numbers in macosx files.

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

	* unix/tclUnixPort.h: add Darwin specifc configure overrides to support
	fat compiles, where configure runs only once for multiple architectures
	(replaces Darwin CVS fix by emoy, rdar://3693001).

	* macosx/tclMacOSXBundle.c:
	* macosx/tclMacOSXNotify.c:
	* unix/tclUnixNotfy.c:
	* unix/tclUnixPort.h: fix #include order to support compile time
	override of HAVE_COREFOUNDATION in tclUnixPort.h when building for
	ppc64

	* macosx/Tcl.pbproj/default.pbxuser (new file):
	* macosx/Tcl.pbproj/jingham.pbxuser:
	* macosx/Tcl.pbproj/project.pbxproj:
	* macosx/Tcl.xcode/default.pbxuser (new file):
	* macosx/Tcl.xcode/project.pbxproj (new file):
	* macosx/Tcl.xcodeproj/default.pbxuser (new file):
	* macosx/Tcl.xcodeproj/project.pbxproj (new file): new/updated
	projects for Xcode 2.2 on 10.4, Xcode 1.5 on 10.3 & ProjectBuilder on
	10.2, with native tcltest targets and support for universal (fat)
	compiles.

	* macosx/README: clarification/cleanup, document new Xcode projects and
	universal (fat) builds via CFLAGS (i.e. all of ppc ppc64 i386 at once).

	* unix/Makefile.in:
	* unix/aclocal.m4:
	* unix/configure.in:
	* unix/dltest/Makefile.in:
	* macosx/configure.ac (new file): add support for inclusion of
	unix/configure.in by macosx/configure.ac, allows generation of a config
	headers enabled configure script in macosx (required by Xcode
	projects).

	* macosx/GNUmakefile: rename from Makefile to avoid overwriting by
	configure run in tcl/macosx, add support for reusing configure cache,
	build target fixes, remove GENERIC_FLAGS override now handled by
	tcl.m4.

	* generic/tcl.decls: add Tcl_Main declaration as comment to avoid
	'checkstubs' target complaining about it missing from stubs.

	* generic/regex.h:
	* generic/tclDate.c:
	* generic/tclEnv.c:
	* generic/tclGetDate.y:
	* generic/tclIOUtil.c:
	* generic/tclObj.c:
	* generic/tclStubInit.c:
	* generic/tclStubLib.c:
	* generic/tclPathObj.c:
	* generic/tclThreadAlloc.c:
	* generic/tclThreadStorage.c:
	* generic/tclTrace.c:
	* generic/tclVar.c:
	* generic/tommath.h:
	* tools/fix_tommath_h.tcl:
	* unix/tclUnixFCmd.c: ensure externally visible symbols not contained
	in stubs table are declared as MODULE_SCOPE (or as static if not used
	outside of own source file). These changes allow 'make checkstubs' to
	complete without error on Darwin with gcc 4.

	* generic/rege_dfa.c (getvacant):
	* generic/regexec.c (cfind):
	* generic/tclCompExpr.c (CompileSubExpr):
	* generic/tclNamesp.c (NamespaceEnsembleCmd):
	* unix/tclUnixChan.c (TclUnixWaitForFile): initialise variables to
	silence gcc 4 warnings.

	* generic/tclExecute.c (TclExecuteByteCode): fix unused variable
	warning when NO_WIDE_TYPE is defined.

	* generic/regguts.h: only #define NDEBUG if not already #defined.

	* unix/tclUnixNotfy.c:
	* macosx/tclMacOSXNotify.c: sync whitespace & comments.

	* unix/tclUnixPort.h:
	* win/tclWinPort.h: remove declaration of obsolete&unused TclpMutex
	API.

	* unix/configure:
	* unix/tclConfig.h.in: regen.

2005-11-21  Andreas Kupries  <andreask@activestate.com>

	* unix/Makefile.in (install-libraries): Updated Makefile to new
	* win/Makefile.in (install-libraries):  version of the http package.
	This fixes the ifneeded/provide mismatch reported when trying to
	require http. Should we maybe try to automatically extract the version
	number from the http code to prevent future breakage ?

	This follows the update of the version number by dgp on Nov 15 (No
	entry found in the ChangeLog).

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

	* generic/tclStubLib.c: Don't set tclStubsPtr to 0 when
	Tcl_PkgRequireEx() fails [Fix for [Bug 1091431] "Tcl_InitStubs failure
	crashes wish"]

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

	* tests/trace.test (trace-34.5): [Bug 1047286], added a second test
	illustrating the role of "ns in callStack" in the ns's visibility
	during deletion traces.

2005-11-18  Kevin B. Kenny  <kennykb@acm.org>

	* doc/clock.n: Restored several missing lines near the %w format group
	so that %w and %W are documented with their actual behaviour. [Bug
	1359183]

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

	* generic/tclIO.c (TclFinalizeIOSubsystem): preserve statePtr until we
	retrieve the next statePtr from it.

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

	* generic/tclObj.c (GetBignumFromObj): replace NULL with
	tclEmptyStringRep to stop memcpy from complaining in a debug build
	(the corresponding branch is eliminated by the optimiser otherwise).

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

	* generic/tclIO.c (TclFinalizeIOSubsystem): Applied Pat Thoyts' patch
	for [Bug 1359094]. This moves the retrieval of the next channel state
	to the end of the loop, as the called closeproc may close other
	channels, i.e. modify the list we are iterating, invalidating any
	pointer retrieved earlier.

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

	* generic/tclListObj.c:	Restored the SetListFromAny routine to the
	* generic/tclObj.c:	"list" Tcl_ObjType, and restored the
	Tcl_RegisterObjType() call for "list". This addresses the needs of some
	"bridge" extensions to examine whether the Tcl_ObjType of a Tcl_Obj is
	that of the "list" Tcl_ObjType.

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

	* library/http/http.tcl (http::geturl): Improved syntactic validation
	of URLs, and better error messages in some cases. [Bug 1358369]

2005-11-17  Miguel Sofer  <msofer@users.sf.net>

	* tests/namespace.test: fix comment

2005-11-14  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStrToD.c:	More data in the "can't happen" Tcl_Panic to
	aid debugging.

	* generic/tclBasic.c (CallCommandTraces): Save/restore the interp
	result during traces to fix [Bug 1355342].

2005-11-13  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInt.h:
	* generic/tclNamesp.c:
	* tests/namespace.test: fix for [Bug 1354540] and [Bug 1355942]. The
	new tests 7.3-6 and the modified 51.13 fail due to the unrelated [Bug
	1355342]

	* tests/trace.test: added tests 20.13-16 for [Bug 1355342]

2005-11-12  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken):
	* generic/tclObj.c (Tcl_GetCommandFromObj): more partial fixes for
	[Bug 1354540] - making sure that cached references to a command being
	deleted cannot be made reusable by a delete trace.

2005-11-12  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclNamesp.c (Tcl_FindCommand): Do not find commands in dead
	namespaces on the path. Partial fix for [Bug 1354540].

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

	* generic/tclInt.h:	Revised TclParseNumber interface to enable
	* generic/tclScan.c:	revision to the [scan] command implementation
	* generic/tclStrToD.c:	to permit tests scan-4.44,55 to pass again.
	[Bug 1348067].

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

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken):
	* generic/tclObj.c (Tcl_GetCommandFromObj): bump the cmd epoch early
	to insure that cached references to this command are invalidated.
	Partial fix for [Bug 1352734] - at least insures that namespace-51.13
	does not cause a panic. The test is still marked as knownbug, pending
	resolution of what is actually the correct return value ([Bug
	1354540])

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

	* generic/tclTimer.c: Changed [after] so that it behaves correctly
	* tests/timer.test:   with negative arguments [Bug 1350293] and
	arguments that overflow a 32-bit word. [Bug 1350291]

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

	* tests/compile.test:	Updated tests with changed behavior
	* tests/execute.test:	due to addition of bignums.
	* tests/expr-old.test:
	* tests/expr.test:
	* tests/parseExpr.test:
	* tests/platform.test:
	* tests/string.test:

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

	* unix/tclUnixFCmd.c (MAX_READDIR_UNLINK_THRESHOLD): reduce to 130
	based on errors seen on OS X 10.3 with lots of links in a dir.
	[Bug 1034337 followup]

2005-11-09  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* unix/Makefile.in (gdb-test): Added a new target to make it easier to
	run the test suite inside a debugger.

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

	* tests/compExpr-old.test:	Updated tests with changed behavior due
	to addition of bignums.

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

	* generic/tclPkg.c:	Corrected inconsistencies in the value returned
	* tests/pkg.test:	by Tcl_PkgRequire(Ex) so that the returned
	values will always agree with what is stored in the package database.
	This way repeated calls to Tcl_PkgRequire(Ex) have the same results.
	Thanks to Hemang Lavana. [Bug 1162286].

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

	* generic/tclTrace.c (TraceVarEx): Factor out heart of Tcl_TraceVar2
	(TclTraceVariableObjCmd,TraceVarProc): Use the new internal API to
	arrange for the clientData to be cleaned up at the same time as the
	rest of the main trace record. This simplifies the code a bit at the
	same time.

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

	* tests/trace.test (trace-13.2-4): added tests to detect leak, see [Bug
	1348775]. The recently added trace-8.9 test is now 13.4.

2005-11-07  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* tests/dict.test (dict-19.2): arrange for the stress testing code to
	only stress test the dict code and not the trace code as well. [Bug
	1342858]

2005-11-05  Miguel Sofer  <msofer@users.sf.net>

	* tests/trace.test (trace-8.9): added test to detect leak, see [Bug
	1348775].

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

	* win/tclWinPort.h:  Applied [Patch 1267871] by Matt Newman for
	* win/tclWinPipe.c:  extended error code support on Windows.
	* tests/exec.test:   Tests for extended error codes.
	* generic/tclPipe.c: Permit long codes (platform macros permitting).

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

	* generic/tclBinary.c:
	* generic/tclCmdAH.c:
	* generic/tclCmdIL.c:
	* generic/tclCmdMZ.c:
	* generic/tclDictObj.c:
	* generic/tclExecute.c:
	* generic/tclIOCmd.c:
	* generic/tclLink.c:
	* generic/tclTest.c:
	* generic/tclVar.c: fix for [Bug 1334947]. The functions TclPtrSetVar,
	Tcl_ObjSetVar2 and Tcl_SetVar2Ex now always consume the newValuePtr
	argument - i.e., they will free a 0-refCount object if they failed to
	set the variable. Fixed all callers in the core.

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

	* generic/tclGetDate.y: Added abbreviations for the Korean
	* library/clock.tcl:    timezone. [Patch 1298737]
	* generic/tclDate.c:    Regenerated.

	* tools/findBadExternals.tcl: Added this script, which locates external
	symbols that do not begin with 'Tcl' or 'tcl' and hence might be in
	conflict with other link libraries. Thanks to George Peter Staplin for
	the idea and the initial version of the script. [Bug 1263012]

	* unix/Makefile.in: Trimmed a bunch of fat out of the tommath/
	directory in 'make dist'. [RFE 1333318]

	* unix/tcl.m4: Added code to enable [load] on LynxOS. Thanks to
	heidibr@users.sf.net for the patch. [Bug 1163896]. Removed the last
	vestiges of GNU dld from the Unix build [RFE 1071992].

	* unix/tclLoadDld.c: Removed.
	* unix/configure: Regenerated.

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

	* generic/tclInt.h:
	* generic/tclNamesp.c:
	* generic/tclVar.c:
	* tests/trace.test: fix for [Bugs 1338280/1337229]; changed to use the
	same approach as the 8.4 patch in the ticket (i.e., removed the patch
	committed on 2005-31-10).

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

	* win/tclWin32Dll.c:   Applied [Patch 1256872] to provide unicode
	* win/tclWinConsole.c: support in the console on suitable systems.
	* win/tclWinInt.h:     Patch by Anton Kovalenko

2005-11-02  Pat Thoyts  <patthoyts@users.sourceforge.net>

	Applied [Patch 1096916] to support building with MSVC 8.
	* generic/regerror.c: Avoid use of reserved word.
	* generic/tcl.h:      Select the right Tcl_Stat structure
	* generic/tclDate.c:  Casts to handle 64 bit time_t case.
	* tests/env.test:     Include essential envvar on Win32
	* win/nmakehlp.c:     Handle new return codes.
	* win/makefile.vc:    Use the selected options.
	* win/rules.vc:       Check options are applicable
	* win/tclWinPort.h:   Disable deprecated function warnings
	* win/tclWinSock.c:   Provide default value to avoid warning.
	* win/tclWinTime.c:   Add casts to handle 64bit time_t type.

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

	* generic/tclTrace.c (TclCheckExecutionTraces): Corrected mistaken
	assumption that all command traces are set at the script level.
	Report/fix from Jacques H. de Villiers. [Bug 1337941]

	* tests/unixNotfy.test (1.1,2):	Update error message whitespace to
	match changes in code.

	* tests/expr-old.test (expr-32.52): Use int(.) to restrict result of
	left shift to the C long range.

	* expr.test (expr-46.13): Added test that illustrates shortcoming of
	[Patch 1340260].

2005-10-31  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclNamesp.c: fix for [Bugs 1338280/1337229]. Thanks Don.
	* tests/trace.test: fix duplicate test numbers

2005-10-31  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* win/tclWinSerial.c (SerialSetOptionProc): Cleaned up option parsing
	to produce more informative error messages and separate error and
	non-error code paths better.
	* tests/ioCmd.test (iocmd-8-19): Updated.

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

	* generic/tclTrace.c (TraceVarProc): [Bug 1337229], partial fix. Ensure
	that a second call with TCL_TRACE_DESTROYED does not lead to a second
	call to Tcl_EventuallyFree(). It is still true that that second call
	should not happen, so the bug is not completely fixed.
	* tests/trace.test (test-18.3-4): added tests for [Bug 1337229] and
	[Bug 1338280].

2005-10-23  Vince Darley  <vincentdarley@sourceforge.net>

	* generic/tclFileName.c: fix to memory leak in glob [Bug 1335006] Obj
	leak detection and patch by Eric Melbardis.

	* tests/fCmd.test:
	* win/tclWinFile.c: where appropriate windows API is available, try to
	set 'nlink' and 'ino' stat fields (previously they were always 0). [Bug
	1325803]

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

	* tests/foreach.test (foreach-8.1): added test for [Bug 1189274]

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

	* generic/tclExecute.c (INST_INCR_*): fixed [Bug 1334570]. Obj leak
	detection and patch by Eric Melbardis.

2005-10-21  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclStrToD.c (RefineApproximation): Plugged a memory leak
	where two intermediate results were not freed on one return path. [Bug
	1334461]. Thanks to Eric Melbardis for the patch.

2005-10-21  Donal K. Fellows  <dkf@users.sf.net>

	* doc/binary.n: Clarify that virtually all code that uses the 'h'
	format in [binary scan] should be using the 'H' format instead. It is
	nearly always a bug to use the other!

2005-10-20  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclListObj.c (TclLsetFlat):
	* tests/lset.test (lset-10.3): fixed handling of unshared lists with
	shared sublists, [Bug 1333036] reported by neuronstorm.

2005-10-19  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclIORChan.c (PassReceivedError,PassReceivedErrorInterp):
	Fix crash caused by passing -1 as the length to TclNewStringObj(). Only
	Tcl_NewStringObj (the function call, not the macro) handles that sort
	of thing correctly. This makes ioCmd.test pass again.

2005-10-19  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclClock.c:		Removed some dead code.
	* generic/tclCmdIL.c:
	* generic/tclCompCmds.c:

	* generic/tclExecute.c:
	* generic/tclLiteral.c:
	* generic/tclParseExpr.c:
	* generic/tclScan.c:
	* generic/tclUtil.c:
	* generic/tclVar.c:

2005-10-19  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclIORChan.c: General cleanup, removing checks that are
	unnecessary due to the general contracts of other functions in the
	core, converting to using ANSI declarations, etc. Note that nearly the
	whole file has changed, but it is often just cosmetic.

2005-10-19  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (INST_DICT_APPEND, INST_DICT_LAPPEND): fixed
	faulty peephole optimisation that can cause crashes, [Bug 1331475]
	reported by Aric Bills.

2005-10-18  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c: Added optimization for I32L64 systems to avoid
	using bignums to perform int multiplies. The improvement shows up most
	dramatically in tclbench's matrix.bench.

2005-10-15  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c:	Restored some optimizations of the
	INST_INCR_SCALAR1_IMM opcode.

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

	* generic/tclIO.c (Tcl_ClearChannelHandlers): removed change dated
	2005-10-04 (see below). Look into [Bug 1323992] for detailed
	discussion.

	* generic/tcl.h: Fixed bad definition of CRTEXPORT which should have
	been CRTIMPORT rather. This broke compilation of generic/tclMain.c and
	was probably introduced by mistake while applying the fix for [Bug
	1256937] below.

2005-10-14  Kevin Kenny  <kennykb@acm.org>

	* generic/tclExecute.c (TclIncrObj, TclExecuteByteCode): Tidied up a
	couple of infelicitous do {...} while(0) constructs.

2005-10-14  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* generic/tcl.h:     Fix for [Bug 1256937] - correctly decorate
	* generic/tclMain.c: imported functions from msvcrt in static builds.

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

	* tests/format.test: "Forward"-port of test updates relating to [Bug
	1284178]. The bug itself was fixed by TIP#237.

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

	* generic/tclIO.c (Tcl_ClearChannelHandlers): temporary ifdef
	TCL_THREADS changes done to de-activate pending event processing when
	channel is being closed/cutted.

2005-10-13  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c:	Removed obsolete use of NO_ERRNO_H.
	* tools/man2tcl.c:
	* unix/tcl.m4:
	* unix/tclConfig.h.in:
	* win/configure.in:

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

	* compat/tclErrno.h:	Removed obsolete file.

	* generic/tclStrToD.c (TclParseNumber): Missing goto caused crash when
	parsing "Na". [Bug 1325833]

2005-10-12  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c (GetNumberFromObj):	Restored some lost
	optimizations for empty string values. We avoid cost of a call to
	TclParseNumber just to tell us an empty string isn't a number.

2005-10-12  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclPathObj.c (SetFsPathFromAny): TclGetString macro must not
	be combined with post-increment arguments. [Bug 1325099]

2005-10-12  Kevin Kenny  <kennykb@acm.org>

	* generic/tclExecute.c (Tcl_ExecuteByteCode, TclIncrObj): Several
	common cases inlined in hopes of gaining a little performance in [incr]

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

	* generic/tclCompCmds.c: New convenience macro CompileTokens().

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

	* generic/tclExecute.c: Corrections to the NO_WIDE_TYPE build. Also
	added missing "break" to a switch that broke wide XOR operations.

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

	* generic/tclInterp.c (DeleteScriptLimitCallback)
	(SetScriptLimitCallback): Improve the interlocking between the script
	limit callback record and the hash table of current such records, to
	prevent crashes in callbacks that create callbacks.
	(Tcl_LimitSetTime): Reset the correct flag. Problem reported by
	Nicolas Castagne <castagne@imag.fr> on comp.lang.tcl

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

	* generic/tclExecute.c: Fixing errors in last commit. (Two commits, the
	second removes wrong comment).

2005-10-09  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:
	* generic/tclExecute.c:
	* generic/tclStrToD.c:
	* generic/tclStringObj.c: Initialise variables to avoid compiler
	warnings ([Bug 1320818] among others).

2005-10-08  Don Porter  <dgp@users.sourceforge.net>

	TIP#237 IMPLEMENTATION

	[kennykb-numerics-branch] Resynchronized with the HEAD; at this
	checkpoint [-rkennykb-numerics-branch-20051008], the HEAD and
	kennykb-numerics-branch contain identical code.

	[kennykb-numerics-branch]	Merge updates from HEAD

	* generic/tclExecute.c: More performance macros and special handling of
	the wide integer type for performance on 32-bit systems.

2005-10-07  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Macro GetNumberFromObj() is version of
	TclGetNumberFromObj() that saves a function call for common uses.

	* generic/tclInt.h:	Made #undef NO_WIDE_TYPE the default on 32-bit
	systems. Being able to use 64-bit values without leaping to mp_int
	should help with performance.

	* generic/tclObj.c:	Bug fixes in the #undef NO_WIDE_TYPE
	* generic/tclExecute.c:	configuration.

	* generic/tclExecute.c: Improved performance of comparison opcodes and
	bitwise operations and removed yet more dead code.

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

	* unix/tclUnixFCmd.c (TraverseUnixTree): Adjust 2004-11-11 change to
	* tests/fCmd.test (fCmd-20.2):           account for NFS special files
	with a readdir rewind threshold. [Bug 1034337]

2005-10-06  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Improved performance of INST_RSHIFT and
	INST_LSHIFT.

2005-10-05  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclExecute.c: Improved performance of INST_MULT, INST_DIV,
	INST_ADD, and INST_SUB and replaced a "goto... label" with a "break
	from loop" in TclIncrObj() and removed some dead code.

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

	* generic/tclPipe.c (TclCreatePipeline): Fixed [Bug 1109294]. Applied
	the patch provided by David Gravereaux.

	* doc/CrtChannel.3: Fixed [Bug 1104682], by application of David
	Welton's patch for it, and added a note about wideSeekProc.

	* generic/tclIORChan.c (RcClose): Removed unreachable panic/return
	statements. This fixes the remainder of [Bug 1286256].

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

	* tests/env.test (env-6.1):
	* win/tclWinPort.h: define USE_PUTENV_FOR_UNSET 1
	* generic/tclEnv.c (TclSetEnv, TclUnsetEnv): add USE_PUTENV_FOR_UNSET
	to existing USE_PUTENV define to account for various systems that have
	putenv(), but can't unset env vars with it. Note difference between
	Windows and Linux for actually unsetting the env var (use of '=').
	Correct the resizing of the environ array. We assume that we are in
	full ownership, but that's not correct.[Bug 979640]

2005-10-04  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]
	* generic/tclExecute.c: Updated TclIncrObj() to more efficiently add
	native long integers. Also updated IllegalExprOperandType and the
	INST_UMINUS, INST_UPLUS, INST_BITNOT, and INST_TRY_CVT_TO_NUMERIC
	sections for performance.

	* generic/tclBasic.c: Updated more callers to make use of
	TclGetNumberFromObj. Removed some dead code.

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

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

	* tests/http.test:              do not URI encode -._~ according
	* library/http/http.tcl (init): to RFC3986. [Bug 1182373] (aho)

	* unix/tclLoadShl.c (TclpDlopen): use DYNAMIC_PATH on second shl_load
	only. [Bug 1204237]

	* doc/scan.n: scan %[] requires "one or more chars" [Bug 1277503]

	* tests/winFile.test (getuser): allow valid Windows usernames. [Bug
	1311285]

	* generic/tclParse.c (Tcl_ParseCommand): add code that recognizes {} in
	addition to {expand} for word expansion (make with
	-DALLOW_EMPTY_EXPAND).

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

	* generic/tclIO.c (Tcl_ClearChannelHandlers): now deletes any
	outstanding timer for the channel. Also, prevents events still in the
	event queue from triggering on the current channel.

	* generic/tclTimer.c (Tcl_DeleteTimerHandler): bail out early if passed
	NULL argument.

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

	[kennykb-numerics-branch]

	* generic/tclBasic.c:	Re-implemented ExprRoundFunc and
	ExprEntierFunc to use TclGetNumberFromObj.

	* generic/tclInt.h:	Added new routine TclGetNumberFromObj to
	* generic/tclObj.c:	provide efficient access to the actual
	internal rep of a numeric Tcl_Obj without conversions.

2005-10-03  Kevin Kenny  <kennykb@acm.org>

	* tools/loadICU.tcl:  Changed the file names of message catalogs to
			      lowercase.
	* tools/makeTestCases.tcl:
	* library/tzdata/*:   Olson's tzdata2005n.tar.gz. Includes new DST
	rules for USA and a number of changes to other locales.
	* tests/clock.test:   Regenerated for new US DST rules.

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

	* generic/tclMain.c: Separate encoding conversion of command line
	arguments from list formatting. [Bug 1306162].

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

	[kennykb-numerics-branch]

	* generic/tclStringObj.c:	Bug fix: Missing cast to large enough
	integral size before << operations led to broken [format %llx] results.
	Thanks to Robert Henry for reporting the bug.

2005-09-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* doc/mathfunc.n:   implementation for TIP #255, expr min/max
	* library/init.tcl:
	* tests/info.test, tests/expr-old.test:

2005-09-27  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tcl.h:	Changed name of the new Tcl_Obj intrep field
	* generic/tclObj.c:	from "bignumValue" to "ptrAndLongRep" as
	* generic/tclProc.c:	described in TIP 237, and more suitable for
	other more general uses.

2005-09-27  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* tests/binary.test (binary-14.18): Added test for [Bug 1116542] though
	the bug itself was already fixed by unrelated changes.

2005-09-26  Kevin Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch] Merge updates from HEAD.

2005-09-26  Kevin Kenny  <kennykb@acm.org>

	* libtommath/:                   Updated to release 0.36.
	* generic/tommath.h:             Regenerated.
	* generic/tclTomMathInterface.h: Added ten missing aliases for mp_*
	functions to avoid namespace pollution in Tcl's exported symbols. [Bug
	1263012]

2005-09-23  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* unix/Makefile.in:	Added -DMP_PREC=4 switch to all compiles so
	* win/Makefile.in:	that minimum memory requirements of mp_int's
	* win/makefile.vc:	will not be quite so large. [Bug 1299153].

	* generic/tclStrToD.c:	Fixed memory leak. [Bug 1299803].
	* generic/tclObj.c:

2005-09-20  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Revise TclIncrObj() to call
	Tcl_GetBignumAndClearObj.

	* generic/tcl.decls:	Add Tcl_GetBignumAndClearObj.
	* generic/tclObj.c:

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

2005-09-16  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclInt.h:		 Added TclBNInitBigNumFromWideInt() so
	* generic/tclTomMathInterface.c: that every caller isn't required to
	duplicate the sign logic to use the unsigned interface.

	* generic/tclBasic.c:	Reduce the number of places where Tcl intrudes
	* generic/tclExecute.c:	into the internal format details of the mp_int
	* generic/tclObj.c:	struct.
	* generic/tclStrToD.c:
	* generic/tcLStringObj.c:

	* generic/tclTomMath.h:	Added mp_cmp_d to routines from libtommath
	* unix/Makefile.in:	used by Tcl.
	* win/Makefile.in:
	* win/makefile.vc:

	* libtommath/bn_mp_add_d.c: Bug fix. For mp_add_d(&a, d, &c), when &a
	has the value -d, then the value &c computed should be zero, but
	mp_add_d was producing an inconsistent zero value with a sign field of
	MP_NEG, something like a value of -0, which other routines in
	libtommath can't handle.

	* generic/tclExecute.c:	Dropped all creation of "bigOne" values and
	just use tommath routines that accept the value "1" directly.

2005-09-15  Miguel Sofer  <msofer@users.sf.net>

	* doc/ParseCmd.3: copy/paste fix [Bug 1292427]

2005-09-15  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]	Merge updates from HEAD.

	* generic/tclStringObj.c (TclAppendFormattedObjs):	Revision to

2005-09-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/tcl.m4 (SC_TCL_EARLY_FLAGS): Added extra hack to allow Tcl to
	transparently open large files on RHEL 3. [Bug 1287638]

2005-09-14  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclStringObj.c:	Bug fixes: ObjPrintfVA needed to
	support "*" fields and needed to interpret precision limits on %s
	conversions as a maximum number of bytes, not Tcl_UniChars, to take
	from the (char *) argument.

	* generic/tclBasic.c:	Updated several callers to use
	* generic/tclCkalloc.c: TclFormatToErrorInfo() and/or
	* generic/tclCmdAH.c:	TclObjPrintf().
	* generic/tclCmdIL.c:
	* generic/tclCmdMZ.c:

	* generic/tclExecute.c:
	* generic/tclIORChan.c:
	* generic/tclIOUtil.c:
	* generic/tclNamesp.c:
	* generic/tclProc.c:

	* library/init.tcl:	Keep [unknown] in sync with errorInfo
	formatting rules.

2005-09-13  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:	First caller of TclFormatToErrorInfo.

	* generic/tclInt.h:		Using stdarg.h conventions, add more
	* generic/tclStringObj.c:	fixed arguments to TclFormatObj() and
	TclObjPrintf(). Added new routine TclFormatToErrorInfo().

	* generic/tcl.h:	Explicitly standardized on the use of stdarg.h
	* generic/tclBasic.c:	conventions for functions with variable number
	* generic/tclInt.h:	of arguments. Support for varargs.h has been
	* generic/tclPanic.c:	implicitly gone for some time now. All
	* generic/tclResult.c:	TCL_VARARGS* macros purged from Tcl sources,
	* generic/tclStringObj.c:	leaving only some deprecated #define's
	* tools/genStubs.tcl:	in tcl.h for the sake of older extensions.

	* generic/tclDecls.h:	make genstubs

	* doc/AddErrInfo.3:	Replaced all documented requirement for use of
	* doc/Eval.3:		TCL_VARARGS_START() with requirement for use of
	* doc/Panic.3:		va_start().
	* doc/SetResult.3:
	* doc/StringObj.3:

2005-09-12  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]	Merge updates from HEAD.

	* generic/tclCmdAH.c:		Added support for the "ll" width
	* generic/tclStringObj.c:	specifier to [format].

	* generic/tclStringObj.c (TclAppendFormattedObjs):	Bug fix: make
	sure %ld formats force the collection of a wide value, when the value
	could be a different long.

2005-09-09  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIORChan.c (RcDecodeEventMask): Added missing type
	declaration for the parameter 'mask'. This fixes the [Bug 1286256]. The
	other warning can be removed only by removing the panic/return code.

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

	[kennykb-numerics-branch]	Merge updates from HEAD.

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

	* generic/tclStringObj.c:  Added two missing casts to silence messages
	from MSVC6.

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

	* generic/tclInt.h:		New internal routine TclObjPrintf()
	* generic/tclStringObj.c:	is similar to TclFormatObj() but
	accepts arguments in non-Tcl_Obj format.

	* generic/tclInt.h:		New internal routines TclFormatObj()
	* generic/tclStringObj.c:	and TclAppendFormattedObjs() to offer
	sprintf()-like means to append to Tcl_Obj. Work in progress toward
	[RFE 572392].

	* generic/tclCmdAH.c:	Compiler directive NEW_FORMAT when #define'd
	directs the [format] command to be implemented in terms of the new
	TclAppendFormattedObjs() routine.

2005-09-08  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	TIP#254 IMPLEMENTATION

	* generic/tclLink.c (LinkTraceProc,ObjValue): Added many new of C var
	* generic/tcl.h:			      to link to, making it
	* doc/LinkVar.3:			      easier to seamlessly
	* generic/tclTest.c (TestlinkCmd):	      couple C code and Tcl
	* tests/link.test:			      scripts in an
	application. [Patch 1242844]

2005-09-07  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclUtf.c (Tcl_UniCharToUtf):	Corrected handling of negative
	* tests/utf.test (utf-1.5):	    Tcl_UniChar input value. Incorrect
	handling was producing byte sequences outside of Tcl's legal internal
	encoding. [Bug 1283976].

2005-09-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInt.h (List): Added flag to keep track of whether a list
	* generic/tclListObj.c:    with a string rep is provably canonical.
	* generic/tclUtil.c (Tcl_ConcatObj):  Do efficient concatenation and
	* generic/tclBasic.c (Tcl_EvalObjEx): evaluation when the list is
	canonical, and not just when the list is pure. This should make the
	"pure list" hacking introduced in 8.3 much more robust.

2005-09-05  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclObj.c (pendingObjDataKey): Added missing 'static' to stop
	symbol from leaking outside the Tcl library. [Bug 1263012]

2005-09-02  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclScan.c:	Bug fix: The %o, %x, %i formats of [scan] must
	not accept any 0b or 0o prefixes. [scan $s %o] must continue to work
	even with KILL_OCTAL enabled.

	* generic/tclInt.h:	Added TCL_PARSE_SCAN_PREFIXES to the flags
	* generic/tclStrToD.c:	accepted by TclParseNumber.

	[kennykb-numerics-branch]

	* generic/tclObj.c:	TclParseNumber calls meant to parse an integer
	value now pass the TCL_PARSE_INTEGER_ONLY flag.

	* generic/tclScan.c:	Extended [scan] to accept the %lld, %llo, %llx,
	and %lli formats. Numeric scanning is now done via TclParseNumber calls

	* generic/tclInt.h:	Extended TclParseNumber to accept new flag
	* generic/tclStrToD.c:	values TCL_PARSE_INTEGER_ONLY,
	TCL_PARSE_OCTAL_ONLY, and TCL_PARSE_HEXIDECIMAL_ONLY, to give caller
	more control over the parsing rules.

2005-08-31  Vince Darley  <vincentdarley@sourceforge.net>

	* doc/FileSystem.3:
	* unix/tclUnixFile.c:
	* windows/tclWinFile.c: clarify that Tcl_FSMatchInDirectory may be
	called with a NULL interpreter, and fix the code so this is allowed.
	Tcl's core itself (tclEncoding.c:FillEncodingFileMap()) calls this
	with a NULL interpreter.

2005-08-30  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclObj.c:	Extended bignum support to include bignums so
	large they will not pack into a Tcl_Obj. When they outgrow Tcl's string
	rep length limits, a panic will result.

	* generic/tclTomMath.h:	Added mp_sqrt to routines from
	* unix/Makefile.in:	libtommath used by Tcl.
	* win/Makefile.in:
	* win/makefile.vc:

	* generic/tclBasic.c:	Extended sqrt(.) so that range covers the
	entire double range, accepting as many bignums in the domain as that
	will allow.

2005-08-29  Andreas Kupries  <andreask@activestate.com>

	* library/tm.tcl (::tcl::tm::roots): Accepted Don Porter's patch for
	[Bug 1189657]. Syncs the implementation to the specification (TIP #189)

2005-08-29  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]	Merge updates from HEAD.

	* generic/tclBasic.c:	Restored round(.) to the Tcl 8.4 rules.

2005-08-29  Kevin Kenny  <kennykb@acm.org>

	* generic/tclBasic.c (ExprMathFunc): Restored "round away from zero"
	* tests/expr.test (expr-46.*):       behaviour to the "round" function.
	Added test cases for the behavior, including the awkward case of a
	number whose fractional part is 1/2-1/2ulp. [Bug 1275043]

2005-08-26  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c: Moved Tcl_{Cut,Splice}Channel to
	{Cut,Splice}Channel for internal use, and created new public functions
	for Tcl_{Cut,Splice}Channel which walk the whole stack of
	transformations and invoke the necessary thread actions. Added code to
	Tcl_(Un)StackChannel to properly invoke the thread actions when pushing
	and popping transformations on/from a channel.

2005-08-26  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclNamesp.c (NamespaceEnsembleCmd): Reset the result after
	creating an ensemble to clear any result object sharing (potentially
	caused by delete traces) so that we can safely return the name of the
	ensemble. Previously, this caused crashes in Snit's test suite.

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

	* generic/tclListObj.c (UpdateStringOfList): Stop uncontrolled and
	unsafe crashes from happening when working with very large string
	representations. [Bug 1267380]

	* generic/tclExecute.c (TEBC:INST_DICT_LAPPEND): Stop dropping a
	duplicated object on the floor, which was a memory leak (and a wrong
	result too). Thanks to Andreas Kupries for reporting this.

2005-08-25  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch] Merge updates from HEAD

	* generic/tclExecute.c: Bug fix. INST_RSHIFT: shift of negative values
	produced incorrect results.

	* generic/tclExecute.c: Bug fix. INST_*SHIFT opcodes stack management.
	[expr 0<<6] should be 0, not 6.

	* generic/tclBasic.c: Extended the domain of round(.) to all non-Inf,
	non-NaN doubles, using bignums for the result as needed.

	* generic/tclStrToD.c (Tcl_DoubleDigits): Fixed the corner cases of
	* tests/binary.test (binary-65.*)         formatting floating point
	numbers with the largest and smallest possible significands, and added
	test cases for them.

2005-08-24  Kevin Kenny  <kennykb@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclExecute.c: Corrected some TRACE bugs that prevented
	compilation with --enable-symbols=all.
	* generic/tclStrToD.c: Revised commentary to prepare for a renaming of
	the file, removed some dead code, and fixed a bug where
	TclBignumToDouble failed on huge negative numbers.
	* tests/binary.test (binary-65.*): Added missing 'ieeeFloatingPoint'
	to large/small significand tests.
	* tests/expr.test (expr-45.*) Added missing braces around expressions.

2005-08-24  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclBasic.c:	Revised implementation of the ceil(.) and
	* generic/tclInt.h:	floor(.) math functions in light of the
	* generic/tclStrToD.c:	revised comparison operators, so that it is
	always true that ($x <= ceil($x)) and ($x >= floor($x)). The simple
	approach of "convert to double and call ceil() or floor()" could not
	guarantee that.

	* generic/tclExecute.c:	Bug fix: TclBignumToDouble return -Inf when
	appropriate. Removed declarations of removed routines.

	* generic/tclExecute.c: Revised the type promotion rules of the
	comparison operators so that they form proper equivalence classes over
	the set of numeric strings.

2005-08-23  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure.in:
	* win/configure: Regen.

	Modified Tcl_ParseNumber to accept an argument to force interpretation
	as decimal, and modified [scan] to use it. Corrected a bug where Not a
	Number with hexadecimal information bits returned consistently
	incorrect values. #ifdef-ed out some code that is needed only for IBM
	hexadecimal floating point. Fixed bugs in code to handle the corner
	cases of smallest and largest significands. Added test cases to improve
	test coverage in generic/tclStrToD.c. Added test cases for 0b notation
	(TIP #114). Removed TclStrToD, and the static functions that it calls,
	which are now dead code (TclParseNumber now does all input
	floating-point conversions.)

2005-08-23  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclStrToD.c:	Bug fix: set shift magnitude properly whether
	we're expanding to mp_int type or not.

	* generic/tclExecute.c:	Bug fix: ACCEPT_NAN under INST_UMINUS.

	* generic/tclStrToD.c:	New macros TIP_114_FORMATS and KILL_OCTAL to
	configure acceptance of 0o and 0b numbers and rejection of "leading
	zero as octal".

	* generic/tclBasic.c:	Re-used the guts of int(.) and wide(.) math
	functions to perform conversions in OldMathFuncProc.

2005-08-22  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclInt.h:	New ACCEPT_NAN macro to mark code that

	* generic/tclExecute.c:	value at various points.
	* generic/tclLink.c:

	* generic/tclStrToD.c:	Bug fix. Parsing of +/- Infinity was reversed.

	* generic/tclTestObj.c:	Disabled unused [testconvertobj] command.

	* generic/tclObj.c:	Removed now unnecessary tests of the
	* generic/tclStrToD.c:	TCL_WIDE_INT_IS_LONG definition.

	* generic/tclInt.h:	New internal routine TclSetBignumIntRep
	* generic/tclObj.c:	consolidates packing of bignum value into a

	* generic/tclStubInit.c:

	* generic/tclExecute.c:	errno, IS_NAN, IS_INF, LLD no longer called in

	* generic/tclCompExpr.c:	errno no longer used in these files;
	* generic/tclParseExpr.c:	dropped support "hack" for it.

	* generic/tclStrToD.c:	Disabled out of date support "hack" for errno.

	* generic/tclBasic.c:	Eliminated VerifyExprObjType. Initialize errno
	to zero in OldMathFuncProc.

2005-08-19  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclBasic.c:	Updated OldMathFuncProc and ExprAbsFunc to do
	less invasion into numeric Tcl_Obj internals. Made ExprDoubleFunc,
	ExprIntFunc, ExprWideFunc, and ExprRoundFunc bignum-aware. Revised
	ExprSrandFunc error message.

	* generic/tclProc.c:	Wrapped a few tclWideIntType uses in
	* generic/tclCmdMZ.c:	#ifndef NO_WIDE_TYPE.

	* generic/tclInt.h:	#define'd NO_WIDE_TYPE.

	* generic/tclVar.c:	Replaced TclPtrIncrVar and TclPtrIncrWideVar

	* generic/tclDictObj.c:	DictIncrCmd rewrite to use TclIncrObj.

	* generic/tclInt.h:	TclIncrObj static -> internal
	* generic/tclExecute.c:

2005-08-17  George Peter Staplin  <GeorgePS@XMission.com>

	* generic/tclBasic.c: eliminate a namespace clash caused by
	BuiltinFuncTable not being static.

	* generic/tclObj.c: fix a namespace clash caused by a missing
	static for pendingObjData.

2005-08-17  Kevin Kenny  <kennykb@acm.org>

	* generic/tclEvent.c (Tcl_Finalize): Removed a copy-and-paste accident
	that caused a (mostly harmless) double finalize of the load and
	filesystem subsystems.
	* tests/clock.test: Eliminated the bad test clock-43.1, and split
	clock-50.1 into two tests, with a more permissive check on the error
	message for an out-of-range value.

2005-08-17  Kevin Kenny  <kennykb@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclBasic.c (Tcl_Expr{Long,Double}{,Obj}): Updated to
	* generic/tclTest.c:                                deal with
	* tests/expr-old.test:                              bignums (well,
	* tests/expr.test:                                  mostly).
	Added a missing "errno=0;" in ExprUnaryFunc so that spurious error
	returns aren't detected.
	Added test cases for Tcl_Expr* and Tcl_Expr*Obj because there was very
	poor test coverage in those areas.
	* generic/tclParseExpr.c: Reworked parsing of numbers to call
	TclParseNumber rather than trying to do things locally.
	* generic/tclStrToD.c: Corrected a comment. Changed so that *endPtrPtr
	does not include any trailing whitespace.

2005-08-17  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclExecute.c: New routine TclIncrObj to centralize the
	increment operation needed in many places. Updated INST_DICT_INCR_IMM
	to make use of it.

2005-08-16  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Made bit shifting opcodes and INST_MOD
	bignum-aware.

	* tests/scan.test:	Making << bignum-aware means that repeated
	* tests/string.test:	left shifting cannot turn a positive into a
	negative. Revised [int_range] and [largest_int] utility commands in the
	test suite that relied on that happening. Without revision they became
	infinite loops.

	* generic/tclExecute.c:	Made binary bitwise opcodes bignum-aware.

	* generic/tclTomMath.h:	Added mp_or and mp_xor to routines from
	* unix/Makefile.in:	libtommath used by Tcl.
	* win/Makefile.in:
	* win/makefile.vc:

2005-08-15  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]	Updates from HEAD.
	* generic/tclExecute.c:	More revisions to IllegalExprOperandType.
	Merged INST_BITNOT with INST_UMINUS and make it bignum-aware according
	to the rule: ~a = -a - 1. Disabled unused code and noted more TODOs.

	* generic/tclInt.decls: Disabled TclLooksLikeInt() and all callers.
	* generic/tclUtil.c:
	* generic/tclCompCmds.c:

	* generic/tclBasic.c:	Rewrite of VerifyExprObjType().

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

	* generic/tclExecute.c: Updated execution of comparison bytecodes to
	be bignum-aware, routing string compares through INST_STR_CMP.

2005-08-14  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclExecute.c: Updated execution of arithmetic bytecodes to
	be bignum-aware, and to allow calculations on NaN to produce a NaN
	result. INST_UMINUS updated to call mp_neg.

	* generic/tclTomMath.h:	Added mp_and, mp_expt_d, and mp_neg to
	* unix/Makefile.in:	routines from libtommath used by Tcl.
	* win/Makefile.in:
	* win/makefile.vc:

2005-08-13  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclObj.c:	Extended Bignum auto-narrowing to auto-narrow
	to tclWideIntType when appropriate; this helps keep things working as
	the bytecode execution code is migrated to supporting bignums.

	* generic/tclExecute.c:	Major overhaul of IllegalExprOperandType.
	Changed several TclNewFooObj() calls to more logically appropriate
	ones. Added several TODO comments marking opportunies for future work.
	Made more use of the eePtr->constants. Made INST_UMINUS bignum aware.

2005-08-12  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclExecute.c: Simplify doCondJump. Use eePtr->constants as
	result of INST_DICT_NEXT, INST_LAND, and INST_LOR. Separate INST_LNOT
	from INST_UMINUS and simplify.

2005-08-12  Kevin Kenny  <kennykb@acm.org>

	* generic/tclClock.c (MktimeObjCmd):
	* library/clock.tcl (GetSystemTimeZone, LoadZoneinfoFile)
	(ReadZoneinfoFile):
	* tests/clock.test (clock-50.1):
	Added functionality to read /etc/localtime if it exists, so that Tcl's
	time can track system time on Linux even if TZ is not set. Changed
	::tcl::clock::Mktime to check for failure, and added a test case that
	mimics failure but is really success.

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

	[kennykb-numerics-branch]

	* generic/tclExecute.c: Rewrite of INST_LAND/INST_LOR to take advantage
	of loss of "pure double" issues. Merged INST_UPLUS with
	INST_TRY_CVT_TO_NUMERIC and updated to use improved rules for impure
	"double"s as well.

	* generic/tclStrToD.c:	Restored conditional generation of
	tclWideIntType values by TclParseNumber so that Tcl's not completely
	broken while bignum calculation support is incomplete. The NO_WIDE_TYPE
	macro can be used to disable this.

	* generic/tclBasic.c (ExprAbsFunc): First pass making [expr abs(.)]
	bignum-aware.

2005-08-11  Kevin Kenny  <kennykb@acm.org>

	* generic/tclEvent.c:         Eliminated the USE_THREAD_STORAGE option
	* generic/tclInt.h:           (which is on in every build generated by
	* generic/tclThread.c:        by the standard configurator).
	* generic/tclThreadStorage.c: Eliminated the code for thread specific
	* unix/configure:             data without USE_THREAD_STORAGE and
	* unix/tcl.m4:                radically refactored the code for
	* unix/tclConfig.h.in:        USE_THREAD_STORAGE so that it has fewer
	* unix/tclUnixThrd.c:         dependencies on the order of
	* win/configure:              finalization. (Also, made 'make
	* win/Makefile.in:            distclean' on Windows clean just a little
	* win/rules.vc:               bit cleaner.)
	* win/tcl.m4:
	* win/tclWinThrd.c:

2005-08-10  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclTomMath.h:	Added mp_shrink, mp_to_unsigned_bin,
	* unix/Makefile.in:	mp_to_unsigned_bin_n, and mp_unsigned_bin_size
	* win/Makefile.in:	to routines from libtommath used by Tcl.
	* win/makefile.vc:

	* generic/tommath.h:	make gentommath_h

	* generic/tclObj.c:	Substantial rewrite to make all number parsing
	flow through TclParseNumber(). Also established the NO_WIDE_TYPE and
	BIGNUM_AUTO_NARROW #ifdef's to help track the assumptions of different
	portions of the code.

	* generic/tclInt.h:	Added NO_WIDE_TYPE #ifdefs

2005-08-10  Kevin Kenny  <kennykb@acm.org>

	* generic/tclEvent.c (Tcl_Finalize): Pushed Tcl_FinalizeLoad and
	Tcl_ResetFilesystem down after Tcl_FinalizeThreadAlloc because we can't
	unload DLL's until after their TSD keys are finalized. (Note that we'll
	still see aborts if an unloaded DLL has TSD - that still needs to be
	fixed.

	* tests/compExpr-old.test (compExpr-3.8): Made tests conditional on
	* tests/expr.test (expr-3.8):             'unix' because they get
	stack overflows on Win32 threaded builds,

2005-08-09  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclPathObj.c: fix to [file rootname] bug in optimized code

2005-08-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclThreadStorage.c: Stop exposing the guts of the thread

	smallest 32-bit integer. [Bug 1241572]

2005-08-04  Andreas Kupries  <andreask@activestate.com>

	* generic/tclIO.c (CloseChannel): Fixed comment nit, added apparently
	missing word to complete a sentence.

	* generic/tclObj.c (Tcl_DbDecrRefCount): Fixed whitespace nit in panic
	message.

2005-08-04  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch] Updated from HEAD

	* generic/tclObj.c:	Rewrote Tcl_GetBooleanFromObj() and supporting
	routines to make use of TclParseNumber. This reduces the potential
	number of times a string value must be scanned.

	* generic/tclObj.c:	Simplified routines that manage the typeTable.
	Deleted the UpdateStringOfBoolean() routine, that can never be called.

2005-08-03  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Untangled some dependencies in the
	* generic/tclEvent.c:		order of finalization routines.
	* generic/tclInt.h:		[Bug 1251399]
	* generic/tclObj.c:

2005-08-02  Don Porter	<dgp@users.sourceforge.net>

	[kennykb-numerics-branch] Updated from HEAD

2005-07-30  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclLoadDyld.c (TclpDlopen, TclpLoadMemory): workarounds for
	bugs/changes in behaviour in Mac OS X 10.4 Tiger.

2005-07-29  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdIL.c (InfoGlobalsCmd): Even in high-speed mode, still
	have to take care with non-existant variables. [Bug 1247135]

2005-07-28  Mo DeJong  <mdejong@users.sourceforge.net>

	* win/README: Update link to msys_mingw8.zip.

2005-07-28  Don Porter	<dgp@users.sourceforge.net>

	* tests/compExpr-old.test:	Still more conversion of "nonPortable"
	* tests/error.test:		tests into tests with constraints that
	* tests/expr-old.test:		describe the limits of their
	* tests/expr.test:		portability. Also more consolidation
	* tests/fileName.test:		of constraint synonyms.
	* tests/format.test:		wideis64bit, 64bitInts => wideIs64bit
	* tests/get.test:		wideIntegerUnparsed => wideIs32bit
	* tests/load.test:		wideIntExpressions => wideBiggerThanInt
	* tests/obj.test:
	* tests/parseExpr.test:		Dropped "roundOffBug" constraint that
	* tests/string.test:		protected from buggy sprintf.

2005-07-28  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclPipe.c (TclCreatePipeline): Arrange for POSIX systems to
	* unix/tclUnixPipe.c (TclpOpenFile):	 use the O_APPEND flag for
	* tests/exec.test (exec-19.1):		 files opened in a pipeline
	like ">>this". Note that Windows cannot support such access; there is
	no equivalent flag on the handle that can be set at the kernel-call
	level. The test is unix-specific in every way. [Bug 1245953]

2005-07-27  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclUtil.c:	Converted the $::tcl_precision value to be kept
	per-thread to prevent different threads from stomping on each others'
	formatting prescriptions.

	***POTENTIAL INCOMPATIBILITY*** Multi-threaded programs that set the
	value of ::tcl_precision will now have to set it in each thread.

	* tests/expr.test:	Consolidated equivalent constraints into
	* tests/fileName.test:	single definitions and (more precise) names:
	* tests/get.test:	longis32bit, 32bit, !intsAre64bit => longIs32bit
	* tests/listObj.test:	empty => emptyTest; winOnly => win
	* tests/obj.test:	intsAre64bit => longIs64bit
	Also updated some "nonPortable" tests to use constraints that mark
	precisely what about them isn't portable, so the tests can run where
	they work.

	* library/init.tcl ([unknown]): Corrected return code handling in the
	portions of [unknown] that expand incomplete commands during
	interactive operations. [Bug 1214462].

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

	* unix/configure: Regen.
	* unix/configure.in: Check for a $prefix/share directory and add it the
	the package if found. This will check for Tcl packages in
	/usr/local/share when Tcl is configured with the default dist install.
	[Patch 1231015]

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

	* generic/tclBasic.c (Tcl_CallWhenDeleted):	Converted to use
	per-thread counter, rather than a process global one that required
	mutex protection. [RFE 1077194]

	* generic/tclNamesp.c (TclTeardownNamespace):	Re-ordering so that
	* tests/trace.test (trace-34.4):	command delete traces fire
	while the command still exists. [Bug 1047286]

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

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_PROG_TCLSH, SC_BUILD_TCLSH):
	* win/configure: Regen.
	* win/tcl.m4 (SC_PROG_TCLSH, SC_BUILD_TCLSH): Split confused search
	for tclsh on PATH and build and install locations into two macros.
	SC_PROG_TCLSH searches just the PATH. SC_BUILD_TCLSH determines the
	name of the tclsh executable in the Tcl build directory. [Bug 1160114]
	[Patch 1244153]

2005-07-23  Don Porter	<dgp@users.sourceforge.net>

	* library/auto.tcl:	Updates to the Tcl script library to make use
	* library/history.tcl:	of Tcl 8.4 features. Forward port of
	* library/init.tcl:	appropriate portions of [Patch 1237755].
	* library/package.tcl:
	* library/safe.tcl:
	* library/word.tcl:

2005-07-23  Mo DeJong  <mdejong@users.sourceforge.net>

	* tests/string.test: Add string is tests for functionality that was not
	tested.
	* win/README: Update msys + mingw URL. Remove old Cygwin + mingw info.

2005-07-23  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (INST_DICT_*): stop 2 compiler warnings for
	uninitialised variables.

2005-07-23  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclExecute.c (TEBC:INST_DICT_INCR_IMM): Fix the incrementor
	to work correctly with wide values.

2005-07-21  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCompCmds.c (TclCompileDictCmd): First run at a compiler
	* generic/tclExecute.c (TclExecuteByteCode): for dictionaries. Also
	added an instruction to support 'finally'-like clauses, exposed more of
	the dict guts to the rest of the core, and defined a few tests to
	exercise more obscure parts of the compiler's operation that were bugs
	during development.

2005-07-21  Kevin B. Kenny  <kennykb@acm.org>

	* library/ldAout.tcl (***REMOVED***):	Removed support for ancient
	* unix/configure:			BSD's, IRIX 4, RISCos and
	* unix/Makefile.in:			Ultrix. Removed two files whose
	* unix/tcl.m4:				code is used only on those
	* unix/tclLoadAout.c (***REMOVED***):	antique platforms.

	***POTENTIAL INCOMPATIBILITY*** if anyone actually uses those
	platforms; it is to be noted though, that an error in the installer has
	actually not caused a necessary file to be installed on those platforms
	in several releases, and nobody's complained.

2005-07-16  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclStrToD.c (RefineResult):  Plugged a stupid memory leak in
	RefineResult (called from Tcl_StrToD). [Tk Bug 1227781]

2005-07-15  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclClock.c (TclClockLocaltimeObjCmd,ThreadSafeLocalTime):
	* library/clock.tcl (GuessWindowsTimeZone, ClearCaches):
	* tests/clock.test (clock-49.1, clock-49.2):
	Handle correctly the case where localtime() returns NULL to report a
	conversion error. Also handle the case where the Windows registry
	contains timezone values that can be mapped to a tzdata file name but
	the corresponding file does not exist or is corrupted, by falling back
	on a Posix timezone string instead; this last case will avoid calls to
	localtime() in starpacks on Windows. [Bug 1237907]

2005-07-14  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCompile.c: Update to follow style guidelines.
	(TclPrintInstruction): Reorganize to do better printing out of bytecode
	with far fewer "special hacks" for particular opcodes.
	* generic/tclCompile.h: Requires two new opcode types.

2005-07-13  Don Porter	<dgp@users.sourceforge.net>

	* unix/tclUnixSock.c:	Use a ProcessGlobalValue to store the value
	* win/tclWinSock.c:	returned by Tcl_GetHostName() ([info
	hostname]). Also re-order initialization of the value on Windows to
	favor GetComputerName() over gethostname() as a source of the
	information.

2005-07-12  Kevin Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch] Updated from HEAD

	* generic/tclCmdMZ.c (Tcl_StringObjCmd):
	* generic/tclInt.h:
	* generic/tclObj.c (Tcl_GetDoubleFromObj, SetDoubleFromAny)
	(Tcl_GetIntFromObj, SetIntOrWideFromAny):
	* generic/tclStrToD.c (TclParseNumber, etc.):
	* tclTomMathInterface.c (TclBNInitBignumFromWideUInt):
	* tests/obj.test (obj-1.1, obj-2.2, obj-3.1, obj-3.2):

	Initial attempt at an implementation of TIP #249, comprising a unified
	parser and modifications to the Tcl_Get*FromObj routines to use it.
	Further integration of the parser is necessary and planned.

2005-07-12  Donal K. Fellows  <dkf@users.sf.net>

	* doc/lsearch.n: Clarify documentation of -exact option; wording was
	open to misinterpretation by non-English speakers.

2005-07-11  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclExecute.c: General style cleanup.

2005-07-08  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclExecute.c (TclExecuteByteCode): Reimplement long and wide
	type integer division and modulus operations so that the smallest and
	largest integer values are handled properly. The divide operation is
	more efficient since it no longer does a modulus or negation and only
	checks for a remainder when the quotient will be a negative number.
	The modulus operation is now a bit more complex because of a number of
	special cases dealing with the smallest and largest integers.
	* tests/expr.test: Add test cases for division and modulus operations
	on the smallest and largest integer values for 32 and 64 bit types.
	[Patch 1230205]

2005-07-06  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclLink.c:	Simplified LinkTraceProc [Bug 1208108].

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

	* unix/Makefile.in:	Purged use of TCLTESTARGS [RFE 1161550].

	* generic/tclUtil.c:	Converted TclFormatInt() into a macro.
	* generic/tclInt.decls:	[RFE 1194015]
	* generic/tclInt.h:

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

	* generic/tclNamesp.c:	Allow for [namespace import] of a command
	* tests/namespace.test:	over a previous [namespace import] of itself
	without throwing an error. [RFE 1230597]

2005-07-04  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclDictObj.c (DictForCmd, DictFilterCmd): Interlocking of
	dictionary internal representations is now done in the core of the dict
	iterator. Purge the last attempts at doing it at a higher level as they
	didn't work and were no longer needed.

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

	* unix/tclUnixNotfy.c: protect against spurious wake-ups while waiting
	on the condition variable when tearing down the notifier thread [Bug
	1222872].

2005-06-28  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclExecute.c (TclExecuteByteCode): When parsing an integer
	operand for a unary minus expression operator, check for a wide integer
	that is actually LONG_MIN. If found, convert back to a long int type.
	* tests/expr.test: Add constraint for 32bit long int type and 64bit
	wide int type. Add tests that parse the smallest/largest long int and
	wide int values.

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

	* generic/tclEvent.c (Tcl_Finalize):
	* generic/tclInt.h:
	* generic/tclPreserve.c (TclFinalizePreserve): Changed the finalization
	logic so that Tcl_Preserve finalizes after exit handlers run; a lot of
	code called from Tk's exit handlers presumes that Tcl_Preserve will
	still work even from an exit handler.

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

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

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

	* win/tclWinChan.c: More rewriting of __asm__ blocks that implement
	* win/tclWinFCmd.c: SEH in GCC, because mingw's gcc 3.4.2 is not as
	forgiving of violations committed by the old code and caused panics.
	[Bug 1225957]

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

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

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

	* win/tclWinFile.c: Potential buffer overflow. [Bug 1225571] Thanks to
	Pat Thoyts for discovery and fix.

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

	* generic/tclInt.h:			    Changed the finalization
	* generic/tclEvent.c (Tcl_Finalize):	    logic to defer the
	* generic/tclIO.c (TclFinalizeIOSubsystem): shutdown of the pipe
	* unix/tclUnixPipe.c (TclFinalizePipes):    management until after all
	* win/tclWinPipe.c (TclFinalizePipes):	    channels have been closed,
	in order to avoid a situation where the Windows PipeCloseProc2 would
	re-establish the exit handler after exit handlers had already run,
	corrupting the heap. [Bug 1225727] Also corrected a potential read of
	uninitialized memory in PipeClose2Proc [Bug 1225044]

2005-06-21  Andreas Kupries  <andreask@activestate.com>

	* generic/tclInt.h: Followup to change made on 2005-06-18 by Daniel
	Steffen. There are compilers (*) who error out on the redefinition of
	WORDS_BIGENDIAN. We have to undef the previous definition (on the
	command line) first to make this acceptable. (*): AIX native.

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

	* generic/tclFileName.c: Changed [file split] and [file join] to treat
	Windows drive letters similarly to ~ syntax and make sure that they
	appear with "./" in front when they are in intermediate components of
	the path. [Bug 1194458]
	* tests/fileName.test: Added test for the above bug.

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

	* generic/tclBasic.c:	Added missing walk of the list of active
	* generic/tclTrace.c:	traces to cleanup references to traces being
	* generic/tclInt.h:	deleted. [Bug 1201035] Made the walk of the
	* tests/trace.test (trace-34.*): active trace list aware of the
	direction of trace scanning, so the proper correction can be made.
	[Bug 1224585]

2005-06-21  Donal K. Fellows  <dkf@users.sf.net>

	* unix/tcl.m4 (SC_ENABLE_SYMBOLS): Only enable the 'compile' special
	debugging feature when requested in configure.in; removes irrelevant
	junk from the configure files of extensions that use Tcl's tcl.m4.

2005-06-20  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCompile.h (INST_PUSH_RETURN_OPTIONS): New opcode to allow
	* generic/tclCompCmds.c (TclCompileCatchCmd):	   compilation of
	* generic/tclCompile.c:				   TIP#90 catch [Bug
	* generic/tclExecute.c (TclExecuteByteCode):	   1219112]

	* generic/tclCompCmds.c (TclCompileSwitchCmd): Ensure we spill to the
	command form in all cases where it generates an error.

2005-06-20  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Generate an error if a mode
	argument like -exact is passed more than once to the switch command.
	The previous implementation silently accepted invalid switch
	invocations like [switch -exact -glob $str ...].
	* tests/for.test: Check some error cases when invoking continue and
	break inside a for loop next script.
	* tests/switch.test: Add checks for shortened version of a mode
	argument like -exact. Add test for more than one mode argument. Add
	test for odd case of passing a variable as a body script.

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

	* generic/tclInt.h: ensure WORDS_BIGENDIAN is defined correctly with
	fat compiles on Darwin (i.e. ppc and i386 at the same time), the
	configure AC_C_BIGENDIAN check is not sufficient in this case because a
	single run of the compiler builds for two architectures with different
	endianness.

	* unix/tcl.m4 (Darwin): add -headerpad_max_install_names to LDFLAGS to
	ensure we can always relocate binaries with install_name_tool.

	* unix/configure: autoconf-2.59

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

	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Fix for [Bug 1154163]; only
	* tests/format.test: insert 'l' modifier when it is needed.

2005-06-17  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclTimer.c (AfterDelay): Split out the code to manage
	synchronous-delay [after] commands.
	* tests/interp.test (interp-34.10): Time limits and synch-delay [after]
	did not mix well... [Bug 1221395]

2005-06-14  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken): Only delete a
	* tests/namespace.test (namespace-49.2): command from the hashtable on
	reentrant processing if it has not been already deleted; at least three
	deletes of the same command are possible. [Bug 1220058]
	* generic/tclTrace.c (TraceCommandProc): Remove bogus error message
	creation when traces trigger in situations where the command has
	already been deleted.

2005-06-13  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFCmd.c: correct fix to file mkdir 2005-06-09 [Bug 1219176]

2005-06-12  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCompCmds.c: Factor out some common idioms into named forms
	for greater clarity.

2005-06-10  Donal K. Fellows  <dkf@users.sf.net>

	* doc/chan.n: Fold in the descriptive parts of the documentation for
	all the commands that [chan] builds on top of.

2005-06-09  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFCmd.c: fix to race condition in file mkdir [Bug 1217375]

	mention of distinctly-relevant [namespace path] subcommand.

2005-06-07  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclInt.h:		Reduced the Tcl_ObjTypes "index",

	* generic/tclNamesp.c:		"levelReference" to file static scope.
	* generic/tclProc.c:

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

	* win/tclWin32Dll.c: Corrected another buglet in the assembly code for
	stack probing on Win32/gcc. [Bug 1213678]
	* generic/tclObj,c: Added missing 'static' on definition of
	UpdateStringOfBignum, and removed a 'switch' on a 'long long' operand
	(which HP-UX native 'cc' seems unable to handle). [Bug 1215775]

2005-06-01  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	For compatibility with earlier Tcl releases,
	* generic/tclResult.c:	when a command procedure simply does a
	* generic/tclTest.c:	"return TCL_RETURN;" we must interpret that
	* tests/result.test:	the same as
	"return Tcl_SetReturnOptions(interp, Tcl_NewObj());"  [Bug 1209759].

2005-06-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/configure.in, unix/tcl.m4: Standardize generation of help
	messages to always use AC_HELP_STRING and always (except for --with-tcl
	and --with-tk, where the default is complex) say what the default is.

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

	* unix/tclUnixNotfy.c: the notifier thread is now created as joinable
	thread and it is properly joined in Tcl_FinalizeNotifier. This is an
	attempt to fix the [Bug 1082283].

2005-05-30  Zoran Vasiljevic  <vasiljevic@users.sf.net>

	* win/tclWinThrd.c: Fixed [Bug 1204064]

2005-05-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	TIP #229 IMPLEMENTATION

	* generic/tclNamesp.c (Tcl_FindCommand, TclResetShadowedCmdRefs)
	(NamespacePathCmd, SetNsPath, UnlinkNsPath, TclInvalidateNsPath):
	Implementation of the [namespace path] command and the command name
	resolution engine.
	* doc/info.n, doc/namespace.n: Doc updates.
	* tests/namespace.test (namespace-51.*): Test updates.
	* generic/tclResolve.c (BumpCmdRefEpochs, Tcl_SetNamespaceResolvers):
	* generic/tclBasic.c (Tcl_CreateCommand, Tcl_CreateObjCommand): Ensure
	that people don't see stale paths.
	* generic/tclInt.h (Namespace, NamespacePathEntry): Structure defs.
	* generic/tclCmdIL.c (InfoCommandsCmd): Updates to [info commands].

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

	* macosx/Makefile: moved & corrected EMBEDDED_BUILD check.

	* unix/configure.in: corrected framework finalization to softlink stub
	library to Versions/8.x subdir instead of Versions/Current.
	* unix/configure: autoconf-2.59

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

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

2005-05-25  Don Porter	<dgp@users.sourceforge.net>

	TIP#182 IMPLEMENTATION	[Patch 1165062]

	* doc/mathfunc.n:	New built-in math function bool().
	* generic/tclBasic.c:
	* tests/expr.test:
	* tests/info.test:

2005-05-24  Don Porter	<dgp@users.sourceforge.net>

	* library/init.tcl:	Updated [unknown] to be sure the [return]
	* tests/init.test:	options from an auto-loaded command are seen
	correctly by the caller.

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

	* tests/env.test: added DYLD_FRAMEWORK_PATH to the list of env vars
	that need to be handled specially.

	* macosx/Makefile:
	* macosx/README:
	* macosx/Tcl-Info.plist.in (new file):
	* unix/Makefile.in:
	* unix/configure.in:
	* unix/tcl.m4:
	* unix/tclUnixInit.c: moved all Darwin framework build support from
	macosx/Makefile into the standard unix configure/make buildsystem, the
	macosx/Makefile is no longer required to build Tcl.framework (but its
	functionality is still available for backwards compatibility).
	* unix/configure: autoconf-2.59

	* generic/tclIOUtil.c (TclLoadFile):
	* generic/tclInt.h:
	* unix/tcl.m4:
	* unix/tclLoadDyld.c: added support for [load]ing .bundle binaries in
	addition to .dylib's: .bundle's can be [unload]ed (unlike .dylib's),
	and can be [load]ed from memory, e.g. directly from VFS without needing
	to be written out to a temporary location first. [Bug 1202209]
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

	* generic/tclCmdMZ.c (Tcl_TimeObjCmd): change [time] called with a
	count > 1 to return a string with a float value instead of a rounded
	off integer. [Bug 1202178]

	* doc/expr.n:
	* doc/string.n: fixed roff syntax complaints from 'make html'.

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

	* generic/tclParseExpr.c:	Corrected parser to recognize all
	boolean literals accepted by Tcl_GetBoolean, including prefixes like
	"y" and "f", and to allow "eq" and "ne" as function names in the proper
	context. [Bug 1201589].

2005-05-19  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclBasic.c (TclEvalObjvInternal): Rewrite for greater
	clarity; although 'goto' is Bad, the contortions you have to go through
	to avoid it can be worse...

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

	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier): fixed crashing CFRelease
	of runLoopSource in Tcl_InitNotifier (reported by Zoran):
	CFRunLoopAddSource doesn't CFRetain, so can only CFRelease the
	runLoopSource in Tcl_FinalizeNotifier.

2005-05-18  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_ExprBoolean):	Rewrite as wrapper around
	Tcl_ExprBooleanObj.

	* generic/tclCmdMZ.c ([string is boolean/true/false]): Rewrite dropping
	string-based Tcl_GetBoolean call, so that internal reps are kept for
	subsequent quick boolean operations.

	* generic/tclExecute.c:	Dropped most special handling of the "boolean"
	Tcl_ObjType, since that type should now be rarely encountered.

	* doc/BoolObj.3:	Rewrite of documentation dropping many details
	about the internals of Tcl_Objs. Shorter documentation focuses on the
	function and use of the routines.

	* generic/tclInt.h:	Revision to the "boolean" Tcl_ObjType, so that
	* generic/tclObj.c:	only string values like "yes" and "false" are
	* tests/obj.test:	kept as the "boolean" Tcl_ObjType. The string
	values "0" and "1" are kept as "int" Tcl_ObjType, which also produce
	quick calls to Tcl_GetBooleanFromObj(). Since this internal change
	means a Tcl_ConvertToType to a "boolean" Tcl_ObjType might not produce
	a Tcl_Obj of type "boolean", the registration of the "boolean" type is
	also removed.
	***POTENTIAL INCOMPATIBILITY***
	For callers of Tcl_GetObjType on the type name "boolean".

2005-05-17  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclObj.c (TclInitObjSubsystem):	Removed the
	* tests/listObj.test:	registration of the Tcl_ObjType's "list",
	* tests/obj.test:	"procbody", "index", "ensembleCommand",
	"localVarName", and "levelReference". The only reason to register a
	Tcl_ObjType is to have it returned by Tcl_GetObjType, and the only
	reason for that is to retrieve a (Tcl_ObjType *) to pass to
	Tcl_ConvertToType(). None of the types above can support a
	Tcl_ConvertToType() call; they panic. Better not to offer something
	than to lead users into a panic.
	***POTENTIAL INCOMPATIBILITY***
	For callers of Tcl_GetObjType on the type names listed above.

2005-05-15  Kevin Kenny  <kennykb@users.sourceforge.net>

	* win/tclWin32Dll.c: conditioned definition of EXCEPTION_REGISTRATION
	structures on HAVE_NO_SEH, to fix a bug in buildability on MSVC.

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

	* generic/tclInt.decls:
	* generic/tclTest.c:
	* generic/tclUtil.c:
	* win/tclWin32Dll.c: fixed link error due to direct access by tclTest.c
	to the MODULE_SCOPE tclPlatform global: renamed existing
	TclWinGetPlatform() accessor to TclGetPlatform() and moved it to
	generic code so that it can be used by on all platforms where
	MODULE_SCOPE is enforced.

	* macosx/tclMacOSXBundle.c:
	* unix/tclUnixInit.c:
	* unix/tcl.m4 (Darwin): made use of CoreFoundation API configurable and
	added test of CoreFoundation availablility to allow building on ppc64,
	replaced HAVE_CFBUNDLE by HAVE_COREFOUNDATION; test for availability of
	Tiger or later OSSpinLockLock API.

	* unix/tclUnixNotfy.c:
	* unix/Makefile.in:
	* macosx/tclMacOSXNotify.c (new file): when CoreFoundation is
	available, use new CFRunLoop based notifier: allows easy integration
	with other event loops on Mac OS X, in particular the TkAqua Carbon
	event loop is now integrated via a standard tcl event source (instead
	of TkAqua upon loading having to finalize the exsting notifier and
	replace it with its custom version). [Patch 1202052]

	* tests/unixNotfy.test: don't run unthreaded tests on Darwin since
	notifier may be using threads even in unthreaded core.

	* unix/tclUnixPort.h:
	* unix/tcl.m4 (Darwin): test for thread-unsafe realpath during
	configure, as Darwin 7 and later realpath is threadsafe.

	* macosx/Makefile: enable configure caching.

	* unix/configure.in: wrap tclConfig.h header in #ifndef _TCLCONFIG so
	that it can be included more than once without warnings from gcc4.0 (as
	happens e.g. when including both tclInt.h and tclPort.h)

	* macosx/tclMacOSXBundle.c:
	* unix/tclUnixChan.c:
	* unix/tclLoadDyld.c:
	* unix/tclUnixInit.c: fixed gcc 4.0 warnings.

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

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

2005-05-13  Kevin Kenny  <kennykb@acm.org>

	* win/tclWin32Dll.c: Further rework of the SEH logic. All
	EXCEPTION_REGISTRATION records are now in the activation record rather
	than pushed on the stack.

2005-05-13  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Dropped the TCL_NO_MATH configuration. It's
	* generic/tclBinary.c:	believed this has not been working in a long
	* generic/tclExecute.c: time. Tcl needs math.h. [RFE 1200680]
	* unix/Makefile.in:

2005-05-12  Kevin Kenny  <kennykb@acm.org>

	* doc/mathfunc.n: Changed NAME line to match the name of the page.

2005-05-11  Kevin Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch] Resynchronized with the HEAD; at this
	checkpoint [-rkennykb-numerics-branch-20050511], the HEAD and
	kennykb-numerics-branch contain identical code.

2005-05-11  Kevin Kenny  <kennykb@acm.org>

	* generic/tclStrToD.c (TclStrToD, RefineResult, ParseNaN): Changed the
	code to cast 'char' to UCHAR explicitly when using ctype macros, to
	silence complaints from the Solaris compiler.

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

	* unix/tclUnixFCmd.c: add lint attr to enum to satisfy strictly
	compliant compilers that don't like trailing ,s.

	* tests/string.test: string-10.[21-30]
	* generic/tclCmdMZ.c (Tcl_StringObjCmd): add extra checks to prevent
	possible UMR in unichar cmp function for string map.

2005-05-10  Kevin Kenny  <kennykb@acm.org>

	* generic/tclBinary.c (FormatNumber): Fixed a bug where NaN's resulted
	in reads of uninitialized memory when using 'd', 'q', or 'Q' format.
	* generic/tclStrToD.c (ParseNaN, TclFormatNaN): Added code to handle
	the peculiarities of HP's PA_RISC, which uses a different 'quiet' bit
	in NaN from everyone else.
	* libtommath/tommath_superclass.h: Corrected C++-style comment.

2005-05-10  Kevin Kenny  <kennykb@acm.org>

	Merged all changes on kennykb-numerics-branch back into the HEAD.
	TIP's 132 and 232 are now Final.

	[kennykb-numerics-branch] Merged changes from HEAD.

2005-05-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (ExponLong, ExponWide):
	* tests/expr.test (expr-23.34/35): fixed special case 'i**0' for i>0
	[Bug 1198892]

2005-05-09  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]
	* win/tclWin32Dll.c (TclpCheckStackSpace, TclWinCPUID): Reworked
	structured event handling to function even with -fomit-frame-pointers.

2005-05-08  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]
	* generic/tclStrToD.c: Made code more portable by finding a workaround
	for MSVC's 'volatile' issue that does not require conditional
	compilation.
	* win/tclWin32Dll.c (TclWinCPUID): Removed structured event handling
	from the GCC code since (a) bad code is generated by the instruction
	scheduling with -O2, and (b) it's not needed on any reasonably modern
	CPU.

2005-05-07  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]
	* generic/tclEvent.c:  Moved initialization of tclStrToD.c's
	* generic/tclInt.h:    static constants into a procedure called
	* generic/tclStrToD.c: from TclInitSubsystems to avoid double checked
	locking protocol. Cleaned up an issue where MSVC ignored the
	'volatile' specifier, causing incorrect comparison of an underflowed
	number against zero.

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

	* unix/tcl.m4, unix/configure: correct Solaris 10 (5.10) check and add
	support for x86_64 Solaris cc builds.

2005-05-05  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch] Merged with HEAD.

2005-05-05  Kevin B. Kenny  <kennykb@acm.org>

	* win/tclWinThrd.c:  Corrected a compilation error on the
			     --enable-threads configuration.

	* generic/tclUtil.c:
	* generic/tclIntDecls.h:	`make genstubs`
	* generic/tclStubInit.c:
	* generic/tclBasic.c:	Added callers of TclMatchIsTrivial where a
	* generic/tclCmdIL.c:	search can be done more efficiently when it is
	* generic/tclCompCmds.c:recognized that a pattern match is really an
	* generic/tclDictObj.c:	exact match. [Patch 1076088]
	* generic/tclIO.c:
	* generic/tclNamesp.c:
	* generic/tclVar.c:

	* generic/tclCompCmds.c:	Factored common efficiency trick into a
	macro named CompileWord.

	* generic/tclCompCmds.c:	Replaced all instance of
	* generic/tclCompile.c:		TCL_OUT_LINE_COMPILE with TCL_ERROR.
	* generic/tclInt.h:		Now that we've eradicated the mistaken
	* tests/appendComp.test:	notion of a "compile-time error", we
	can use the TCL_ERROR return code to signal any failure to produce
	bytecode.

2005-05-03  Don Porter	<dgp@users.sourceforge.net>

	* doc/DString.3:	Eliminated use of identifier "string" in Tcl's
	* doc/Environment.3:	public C API to avoid conflict/confusion with

2005-04-30  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclUnixNotfy.c: applied dkf's tkMacOSXNotify.c cleanup changes.

2005-04-29  Don Porter	<dgp@users.sourceforge.net>

	TIP#176 IMPLEMENTATION	[Patch 1165695]

	* generic/tclUtil.c:	Extended TclGetIntForIndex to recognize index
	formats including end+integer and integer+/-integer.

	* generic/tclCmdMZ.c:	Extended the -start switch of [regexp] and
	[regsub] to accept all index formats known by TclGetIntForIndex.

	* doc/lindex.n:		Updated docs to note new index formats.
	* doc/linsert.n, doc/lrange.n, doc/lreplace.n, doc/lsearch.n:

2005-04-28  Don Porter	<dgp@users.sourceforge.net>

	* tests/unixInit.test (7.1): Alternative fix for the 2004-11-11 commit.

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

	* library/init.tcl:	Corrected flaw in interactive command
	* tests/main.test:	auto-completion. [Bug 1191409].

	* generic/tclIOUtil.c (TclGetOpenModeEx):	New routine.
	* generic/tclInt.h:

	* generic/tclIO.c (Tcl_OpenObjCmd):	Support for "b" and
	* doc/open.n:		"BINARY" in "access" argument to [open].
	* tests/ioCmd.test:

2005-04-26  Kevin B. Kenny  <kennykb@users.sourceforge.net>

	* generic/tclBinary.c (FormatNumber): Dredge the NaN out of the
	internal representation if Tcl_GetDoubleFromObj returns TCL_ERROR on a
	NaN.

	* generic/tclObj.c (Tcl_GetDoubleFromObj): Restored silent
	overflow/underflow behaviour that the merge of 2004-04-25 messed up.
	Thanks to Don Porter for calling attention to this bug. Also removed an
	uninitialised memory reference in this function that valgrind caught.
	Also changed to return TCL_ERROR on a pure NaN.

	* generic/tclStrToD.c (RefineResult): Added a test for the initial
	approximation being HUGE_VAL; this test avoids EDOM being returned from
	ldexp on some platforms on input values exceeding the floating point
	range.

	* tests/expr.test (expr-29.*, expr-30.*): Added further tests of
	overflow/underflow on input conversions.

2005-04-25  Kevin B. Kenny  <kennykb@users.sourceforge.net>

	[kennykb-numerics-branch] Merged with HEAD.

	* doc/CrtMathFunc.n:		Revised documentation for TIP 232

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

	* compat/string.h: fixed memchr() protoype for __APPLE__ so that we
	build on Mac OS X 10.1 again.

	* generic/tclNotify.c (TclFinalizeNotifier): fixed notifier not being
	finalized in unthreaded core (was testing for notifier initialization
	in current thread by checking thread id != 0 but thread id is always 0
	in untreaded core).

	* win/tclWinNotify.c (Tcl_WaitForEvent):
	* unix/tclUnixNotfy.c (Tcl_WaitForEvent): don't call ScaleTimeProc for
	zero wait times (as specified in TIP 233).

	* unix/Makefile.in: added @PLAT_SRCS@ to SRCS and split out NOTIFY_SRCS
	from UNIX_SRCS for parity with UNIX_OBJS & NOTIFY_OBJS.

	* unix/tcl.m4 (Darwin): added configure checks for recently added
	linker flags -single_module and -search_paths_first to allow building
	with older tools (and on Mac OS X 10.1), use -single_module in SHLIB_LD
	and not just T{CL,K}_SHLIB_LD_EXTRAS, added unexporting from Tk of
	symbols from libtclstub to avoid duplicate symbol warnings, added
	PLAT_SRCS definition for Mac OS X, defined MODULE_SCOPE to
	__private_extern__.
	(SC_MISSING_POSIX_HEADERS): added caching of dirent.h check.

	* generic/tclObj.c:	[Bug 1188863].

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

	The 2005-04-21 changes to Tcl_GetBooleanFromObj were done to bring it
	into agreement with its docs. Further investigation reveals it was the
	docs that were incorrect.

	* doc/BoolObj.3:	Corrections to the documentation of
	Tcl_GetBooleanFromObj to bring it into agreement with what this public
	interface has always done, including noting the difference in function
	between Tcl_GetBooleanFromObj and Tcl_GetBoolean.

	* generic/tclGet.c:	Revised Tcl_GetBoolean to no longer be a
	wrapper around Tcl_GetBooleanFromObj (different function!).

	* generic/tclObj.c:	Removed TclGetTruthValueFromObj routine that
	was added yesterday. Revisions so that only Tcl_GetBoolean-approved
	values get the "boolean" Tcl_ObjType. This retains the fix for [Bug
	1187123].
	* tests/string.test:	Test string-23.0 for Bug 1187123.

	* generic/tclInt.h:	Revert most recent change.
	* generic/tclBasic.c:
	* generic/tclCompCmds.c:
	* generic/tclDictObj.c:
	* generic/tclExecute.c:
	* tests/obj.test:

2005-04-21  Don Porter	<dgp@users.sourceforge.net>

	* doc/GetInt.3:	Convert argument "string" to "str" to agree with code.
	Also clarified a few details on int and double formats.
	* generic/tclGet.c:	Radical code simplification. Converted
	Tcl_GetFoo() routines into wrappers around Tcl_GetFooFromObj(). Reduces
	code duplication, and the resulting potential for inconsistency.

	* generic/tclObj.c:	Several changes:

	- Re-ordered error detection code so all values with trailing garbage
	  receive a "not an integer" message instead of an "integer too large"
	  message.
	- Removed inactive code meant to deal with strtoul* routines that fail
	  to parse leading signs. All of them do, and if any are detected that
	  do not, the correct fix is replacement with compat/strtoul*.c, not a
	  lot of special care by the callers.
	- Tcl_GetDoubleFromObj now avoids shimmering away a "wideInt" intrep.
	- Fixed Tcl_GetBooleanFromObj to agree with its documentation and with
	  Tcl_GetBoolean, accepting only "0" and "1" and not other numeric
	  strings. [Bug 1187123]
	- Added new private routine TclGetTruthValueFromObj to perform the more
	  permissive conversion of numeric values to boolean that is needed by
	  the [expr] machinery.

	* generic/tclInt.h (TclGetTruthValueFromObj):	New routine.
	* generic/tclExecute.c:	Updated callers to call new routine.
	* generic/tclBasic.c:	Updated callers to call new routine.
	* generic/tclCompCmds.c:	Updated callers to call new routine.
	* generic/tclDictObj.c:	Updated callers to call new routine.
	* tests/obj.test:	Corrected bad tests that actually expected
	values like "47" and "0xac" to be accepted as booleans.

	* generic/tclLiteral.c: Disabled the code that forces some literals
	into the "int" Tcl_ObjType during registration. We can re-enable it if
	this change causes trouble, but it seems more sensible to let Tcl's
	"on-demand" shimmering rule, and not try to pre-guess things.

2005-04-19  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl (Initialize): Put initialization code into a proc
	to avoid inadvertently clobbering global variables. [Bug 1185933]
	* tests/clock.test (clock-48.1): Added regression test for the above
	bug.
	Thanks to Ulrich Ring for reporting this bug.

2005-04-16  Miguel Sofer  <msofer@users.sf.net>

	* generic/Var.c (Tcl_ArrayObjCmd - ARRAY_NAMES): fix Tcl_Obj leak. [Bug
	1084111]

2005-04-16  Zoran Vasiljevic  <vasiljevic@users.sf.net>

	* generic/tclIOUtil.c: force clenaup of the interp result in
	TclLoadFile(). Some implementations of TclpFindSymbol() will seed the
	interp result with error message when unable to find the requested
	symbol (this is not considered to be an error).

	Set of changes correcting huge memory waste (not a leak) when a thread
	exits. This has been introduced in 8.4.7 within an attempt to correctly
	cleanup after ourselves when Tcl library is being unloaded with the
	Tcl_Finalize() call.

	This fixes the [Bug 1178445]

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

	* generic/tclThreadAlloc.c: modified TclFinalizeThreadAlloc() to
	explicitly call TclpFreeAllocCache with the NULL-ptr as argument
	signalling cleanup of private tsd key used only by the threading
	allocator.

	* unix/tclUnixThrd.c: fixed TclpFreeAllocCache() to recognize when
	being called with NULL argument. This is a signal for it to clean up
	the tsd key associated with the threading allocator.

	* win/tclWinThrd.c: renamed TclWinFreeAllocCache to TclpFreeAllocCache
	and fixed to recognize when being called with NULL argument. This is a
	signal for it to clean up the tsd key associated with the threading
	allocator.

2005-04-13  Don Porter	<dgp@users.sourceforge.net>

	* tests/unixInit.test:	Disabled obsolete tests and removed code
	* tests/encoding.test:	that supported them.
	* generic/tclInterp.c:

	* library/init.tcl:	Use auto-loading to bring in Tcl Module support
	* library/tclIndex:	as needed. This reduces startup time by
	* library/tm.tcl:	delaying this initialization to a later time.

2005-04-15  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: missing semicolons caused failure to compile
	with TCL_COMPILE_DEBUG.

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

	* generic/tclIO.c (Tcl_SetChannelBufferSize): Lowest size limit
	* tests/io.test:	changed from ten bytes to one byte. Need for
	* tests/iogt.test:	this change was proven by Ross Cartlidge
	<rossc@cisco.com> where [read stdin 1] was grabbing 10 bytes followed
	by starting a child process that was intended to continue reading from
	stdin. Even with -buffersize set to one, nine chars were getting lost
	by the buffersize over reading for the native read() caused by [read].

2005-04-13  Don Porter	<dgp@users.sourceforge.net>

	* unix/tclUnixInit.c (TclpGetEncodingNameFromEnvironment): Reversed
	order of verifying candidate [encoding system] value, checking against
	a table in memory first before calling Tcl_GetEncoding and potentially
	scanning through the filesystem. Also ordered the table so that a
	binary search could be used within it. Improves startup time a bit more
	on some systems.

2005-04-13  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.n: Added a missing '--' on several [switch] commands to
	improve performance of [clock format] and related operations. [FRQ
	1182459]

2005-04-13  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* doc/fcopy.n: Improved documentation on copying binary files, added an
	example and mentioned the use of [file copy].
	* doc/fconfigure.n: Improved documentation of -encoding binary option.
	This is all following comments from Steve Manning <steve@manning.net>
	on comp.lang.tcl that the current documentation was not clear.

2005-04-13  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompile.c:Commented out the functions
	TclPrintInstruction(), TclPrintObject() and TclPrintSource() when not
	debugging the compiler, as they are never called in that case.

2005-04-12  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclInterp.c:	Corrected bad syntax of Tcl_Panic() call.

	* generic/tclUtil.c (TclGetProcessGlobalValue):	More robust handling
	of bad TclInitProcessGlobalValueProc behavior; an immediate panic
	rather than a mysterious crash later.

	* generic/tclEncoding.c:	Several changes to the way the
	encodingFileMap cache is maintained. Previously, it was attempted to
	keep the file map filled and up to date with changes in the encoding
	search path. This contributed to slow startup times since it required
	an expensive "glob" operation to fill the cache. Now the validity of
	items in the cache are checked at the time they are used, so the cache
	is permitted to fall out of sync with the encoding search path. Only
	[encoding names] and Tcl_GetEncodingNames() now pay the full expense.
	[Bug 1177363]

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

	* compat/strstr.c: Added default definition of NULL to accommodate
	building on systems with badly broken headers. [Bug 1175161]

2005-04-11  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* tools/tclZIC.tcl: Rewrote to take advantage of more features of Tcl
	8.5 (on which it was dependent anyway). Also added a [package require]
	line to formalize the relationship.

2005-04-11  Kevin Kenny  <kennykb@users.sf.net>

	[kennykb-numerics-branch] Merged with HEAD. Updated to libtommath 0.35.

	* generic/tclBasic.c: Attempted to repeat changes that applied to
	tclExecute.c in Miguel Sofer's commit of 2005-04-01, together with
	(possibly) a few more uses of his new object creation macros. Also
	plugged a memory leak in TclObjInvoke. [Bug 1180368]

	Tcl_Encoding value, as well as cache it in the internal rep of a new
	"encoding" Tcl_ObjType.
	* generic/tclCmdAH.c (Tcl_EncodingObjCmd):	Updated to call new
	function so that Tcl_Encoding's used by [encoding convert*] routines
	are not freed too quickly. [Bug 1077262]

2005-04-08  Donal K. Fellows  <dkf@users.sf.net>

	slightly.

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

	* generic/tclExecute.c (ExprSrandFunc):  Replaced incursions into the
	* generic/tclUtil.c (TclGetIntForIndex): intreps of numeric types with

	* generic/tclListObj.c:
	* generic/tclStubInit.c:
	* generic/tclVar.c: Changed the internal representation of lists to
	(a) reduce the malloc/free calls at list creation (from 2 to 1), (b)
	reduce the cost of handling empty lists (we now never create a list
	internal rep for them), (c) allow refcounting of the list internal rep.
	The latter permits insuring that the pointers returned by
	Tcl_ListObjGetElements remain valid even if the object shimmers away
	from its original list type. This is [Patch 1158008]

	* generic/tclExecute.c:
	* generic/tclInt.h:
	* generic/tclObj.c:
	* generic/tclStringObj.c:
	(1) defined new internal macros for creating and setting frequently
	used obj types (int,long, wideInt, double, string). Changed TEBC to use
	eg 'TclNewIntObj(objPtr, i)' to avoid the function call in 'objPtr =
	Tcl_NewIntObj(i)'
	(2) ExecEnv now stores two Tcl_Obj* pointing to the constants "0" and
	"1", for use by TEBC.
	(3) slight reduction in cost of INST_START_CMD

2005-03-31  Miguel Sofer  <msofer@users.sf.net>

	as part of the 1115904 bug fix on 2005-03-18.

	* generic/tclThreadTest.c:	Stop providing the phony package
	"Thread 1.0" when the [::testthread] command is defined. It's never
	used by anything, and conflicts with loading the real "Thread" package.

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

	* generic/tclCompCmds.c (TclCompileIncrCmd):	Corrected checks for
	immediate operand usage to permit leading space and sign characters.
	Restores more efficient bytecode for [incr x -1] that got lost in the
	CONST string reforms of Tcl 8.4. [Bug 1165671]

	code to handle IEEE signed zeroes in Tcl_DoubleDigits. (It can't be

	in the pure-list branch, in case the list shimmers away. Fix for [Bug
	1119369], reported by Peter MacDonald.

2005-02-10  Vince Darley  <vincentdarley@users.sourceforge.net>

	* generic/tclFileName.c: fix for test failures introduced on 2005-01-17
	[Bug 1119092]

2005-02-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/binary.n: Made the documentation of sign bit masking and [binary
	scan] consistent. [Bug 1117017]

2005-02-08  David N. Welton  <davidw@dedasys.com>

	* doc/CrtChannel.3: Typo: return->returns.

2005-02-06  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]

	* generic/tclStrToD.c (TclStrToD, SafeLdExp): Added code to manage the
	FPU precision on gcc+x86. Enabled fast conversion of floats with small
	exponents now that precision is correct.
	* tests/expr.test: Corrected test for the smallest representible value
	to the right IEEE values.

2005-02-06  David N. Welton  <davidw@dedasys.com>

	* doc/Thread.3: One-word grammar fix.

2005-02-05  David N. Welton  <davidw@dedasys.com>

	* doc/Thread.3: Fixed sentence describing flags for Tcl_CreateThread.

	* doc/FileSystem.3: Cleaned up typo in Tcl_FSNewNativePath
	documentation.

	* generic/tclPathObj.c: Cleaned up typo in comment.

2005-02-03  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]

	* generic/tclStrToD.c (TclStrToD, RefineResult, SafeLdExp): Added code
	to ensure that 'ldexp' is never called with a value that will underflow
	* tests/expr.test: Added tests for the smallest representible value,
	and rounding between it and zero. (The tests reflect current
	behaviour; plan is to change the specification of Tcl so that input
	conversion of doubles underflows silently.)

2005-02-02  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclProc.c (TclInitCompiledLocals): Add check for type of the
	framePtr->procPtr->bodyPtr passed to TclInitCompiledLocals and panic if
	it is not the correct type. If the body of the proc is not of the
	compiled byte code type then the code will crash. This was discovered
	while tracking down a crash in Itcl, that crash is fixed by Itcl patch
	1115085.

2005-02-01  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]  Merged with HEAD as of today.

	* generic/tclInt.decls: Changed numbers of new stubs to resolve a
	conflict.
	* generic/tclInt.h: Added new TclStrToD routine that replaces the
	native 'strtod' throughout Tcl.
	* generic/tclCmdMZ (Tcl_StringObjCmd):
	* generic/tclGet.c (Tcl_GetDouble):
	* generic/tclObj.c (SetBooleanFromAny, SetDoubleFromAny):
	* generic/tclParseExpr.c (GetLexeme):
	* generic/tclScan.c (Tcl_ScanObjCmd): Replaced all uses of the native
	'strtod' with a TclStrToD routine that performs correct rounding and
	handles denormals.
	* generic/tclStrToD.c: (new file)
	New scanning function for extracting 'double' from a string that rounds
	correctly, and handles denormals and infinities.
	* unix/Makefile.in:
	* win/Makefile.in:
	* win/makefile.vc:
	Added tclStrToD.c and the tommath routines that support it.

	These changes represent a partial implementation of TIP #132. Output
	conversion of floating point numbers, and proper handling of infinities
	within expressions, still need to be addressed.

2005-02-01  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c (TclCompEvalObj): Removed stray statement left
	behind in prior code reorganization.

2005-01-31  Don Porter	<dgp@users.sourceforge.net>

	* unix/configure:	autoconf-2.57

2005-01-30  Joe English  <jenglish@users.sourceforge.net>

	* unix/configure.in: Restored two double-evals that were removed in the
	DBGX purge; these are still needed on some platforms to account for
	TCL_TRIM_DOTS. [Bug 1112654]

	* unix/configure: NOT REGENERATED: only have autoconf 2.59 here, need
	to find someone with autoconf 2.57.

2005-01-28  Jeff Hobbs	<jeffh@ActiveState.com>

	* unix/configure, unix/tcl.m4: add solaris 64-bit gcc build support.
	[Bug 1021871]

2005-01-28  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/expr-old.test (expr-old-37.2): Added test for [Bug 1109484]

2005-01-21  Andreas Kupries  <andreask@activestate.com>

	* generic/tclThread.c: Typo police. Fixed some nits
	* generic/tclCmdAH.c:  in header comments of functions.

	remove a FileInfo from the thread local list before deallocating it.
	This should have been done via an earlier call to Tcl_CutChannel, but I
	was running into a crash in the next call to Tcl_CutChannel during the
