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:
        * generic/tclTomMath.decls:
        * generic/tclTomMath.h:
        * generic/tclTomMathDecls.h:
        * generic/tclTomMathInterface.c:
        * generic/tommath.h:
        * 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:
        * generic/tclParseExpr.c:
        * generic/tclProc.c:
        * generic/tclTimer.c:
        * win/tclWinChan.c:
        * win/tclWinConsole.c:
        * win/tclWinDde.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/tclDictObj.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]

        [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
        eliminate one round of string copying.

        * generic/tclBasic.c:   More callers of TclObjPrintf and
        * generic/tclCkalloc.c: TclFormatToErrorInfo.

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/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().

        [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>

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.

2005-09-01  Andreas Kupries  <andreask@activestate.com>

        * unix/tclUnixSock.c (InitializeHostName): Synchronized use of static
        modifier in declaration and definition of function.

        * unix/tclUnixChan.c (FileTruncateProc): Synchronized use of static
        modifier in declaration and definition of function.

        use of static modifier in declaration and definition of function.

        * generic/tclEncoding.c (FillEncodingFileMap): Synchronized use of
        static modifier in declaration and definition of function.

        * generic/tclIORChan.c (RcNewHandle): Synchronized use of static
        modifier in declaration and definition of function.

2005-09-01  Don Porter  <dgp@users.sourceforge.net>

        [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  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.

        * 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.

        * 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.

        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.)

        [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

        [kennykb-numerics-branch]

        * generic/tclInt.h:     New ACCEPT_NAN macro to mark code that
        * generic/tclCmdAH.c:   supports or disables accepting of the NaN
        * 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/tclBasic:     Added [expr {entier(.)}]. Rewrote int(.) and
        wide(.) to use the same guts, accepting all non-Inf doubles as
        arguments.

        * generic/tclInt.h:     New routine TclInitBignumFromDouble.
        * generic/tclStrToD.c:  Modified to return code and write error
        message.

        * generic/tclInt.h:     TCL_WIDE_INT_IS_LONG implies NO_WIDE_TYPE.

        * generic/tclInt.h:             Moved TclParseInteger to tclUtil.c and
        * generic/tclParseExpr.c:       made it static.
        * generic/tclUtil.c:

        * generic/tclInt.decls: Moved TclExprFloatError to tclBasic.c and made

        * generitc/tclIntDecls.h:       make genstubs

        * generic/tclExecute.c: errno, IS_NAN, IS_INF, LLD no longer called in
        this file; dropped/disabled support for them.

        * 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/tclInt.h:     with TclPtrIncrObjVar and replaced TclIncrVar2
        * generic/tclInt.decls: and TclIncrWideVar2 with TclIncrObjVar2. New
        routines call on TclIncrObj to do the work.

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

        * generic/tclCmdIL.c:   Rework Tcl_IncrObjCmd and the INST_*INCR*
        * generic/tclExecute.c: opcodes to use the new routines.

        * 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
        path reported on comp.lang.tcl.

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

        [kennykb-numerics-branch]

        * generic/tclObj.c:     Replaced some goto's with loops and started
        use of BIGNUM_AUTO_NARROW and NO_WIDE_TYPE.

2005-08-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclThreadStorage.c: Stop exposing the guts of the thread
        storage system through the internal stubs table. Client code should
        always use the standard API.

2005-08-05  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclObj.c:     Rewrote Tcl_GetDoubleFromObj().

2005-08-05  Donal K. Fellows  <dkf@users.sf.net>

        * unix/tclUnixInit.c (localeTable): Solaris uses a non-standard name
        for the cp1251 charset. Thanks to Victor Wagner for reporting this.
        [Bug 1252475]

2005-08-05  Kevin Kenny  <kennykb@users.sourceforge.net>

        * win/makefile.vc: Removed unused file ldAout.tcl.
        * win/makefile.bc: [Bug 1244361]

        * tests/binary.test: Cleaned up testing for scanning of NaN. [Bug
        1246264]

        * generic/tclBasic.c (ExprAbsFunc): Added code to handle the corner
        * tests/expr.test (expr-38.1):      case of applying 'abs' to the
        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]

        * 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]

        * 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

        * 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.

        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.

2005-07-06  Don Porter  <dgp@users.sourceforge.net>

        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.

        * 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/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.

        * unix/tcl.m4 (SC_ENABLE_SYMBOLS): Only enable the 'compile' special

        junk from the configure files of extensions that use Tcl's tcl.m4.

        * generic/tclExecute.c (TclExecuteByteCode):       1219112]

        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>

2005-06-17  Donal K. Fellows  <dkf@users.sf.net>

        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/tclInt.h:             Reduced the Tcl_ObjTypes "index",
        * generic/tclIndexObj.c:        "ensembleCmd", "localVarName", and
        * generic/tclNamesp.c:          "levelReference" to file static scope.

        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]

        when multiple Tcl source dirs exist.

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>

        * generic/tclCompCmds.c (TclCompileSwitchCmd): Allow compilation of
        -nocase -glob [switch]es (only one we know how to compile).

        TIP#241 IMPLEMENTATION from Joe Mistachkin

        * generic/tclCmdIL.c (Tcl_LsearchObjCmd, Tcl_LsortObjCmd):

2005-05-31  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

        (NamespacePathCmd, SetNsPath, UnlinkNsPath, TclInvalidateNsPath):
        Implementation of the [namespace path] command and the command name

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.

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.

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

        * generic/tclInt.decls: Converted TclMatchIsTrivial to a macro.
        * generic/tclInt.h:
        * generic/tclUtil.c:
        * generic/tclIntDecls.h:        `make genstubs`
        * generic/tclStubInit.c:
        * generic/tclBasic.c:   Added callers of TclMatchIsTrivial where a

        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

        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__.

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.

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.

2005-04-16  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.

        * 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.

        * 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

        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.

2005-04-08  Donal K. Fellows  <dkf@users.sf.net>

        * generic/tclCompCmds.c (TclCompileSwitchCmd): Rewritten to be able to

        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]

        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

        msys alone as an alternative.

2005-03-24  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclCompile.h: Move the TclInterpReady() declaration from
        * generic/tclInt.h:     tclCompile.h to tclInt.h. Should have been done
        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.

        * generic/tclCompCmds.c (TclCompileIncrCmd):    Corrected checks for

        Restores more efficient bytecode for [incr x -1] that got lost in the
        CONST string reforms of Tcl 8.4. [Bug 1165671]

        TclDoubleDigits so that it accepts a pointer to the signum of the
        argument, and returns the signum via that pointer. Added very hacky
        code to handle IEEE signed zeroes in Tcl_DoubleDigits. (It can't be
        done other than as a hack until C9x; C89 simply doesn't deal with the

        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

        (Tcl_ExprLong): Fix to recognize Tcl_WideInt type. [Bug 1109484]

2005-01-26  Andreas Kupries  <andreask@activestate.com>

        TIP#218 IMPLEMENTATION

        * generic/tclDecls.h:   Regenerated from tcl.decls.
        * generic/tclStubInit.c:

        * doc/CrtChannel.3:     Documentation of extended API,
        * generic/tcl.decls:    extended testsuite, and
        * generic/tcl.h:        implementation. Removal of old
        * generic/tclIO.c:      driver-specific TclpCut/Splice
        * generic/tclInt.h:     functions. Replaced with generic
        * tests/io.test:        thread-action calls through the
        * unix/tclUnixChan.c:   new hooks. Update of all builtin
        * unix/tclUnixPipe.c:   channel drivers to version 4.
        * unix/tclUnixSock.c:   Windows drivers extended to
        * win/tclWinChan.c:     manage thread state in a thread

2005-01-25  Don Porter  <dgp@users.sourceforge.net>

        * library/auto.tcl:     Updated [auto_reset] to clear auto-loaded
        commands in namespaces other than :: and to clear auto-loaded commands
        that do not happen to be procs. [Bug 1101670]
        ***POTENTIAL INCOMPATIBILITY***

2005-01-25  Daniel Steffen  <das@users.sourceforge.net>

        * unix/tcl.m4 (Darwin): fixed bug with static build linking to dynamic
        library in /usr/lib etc instead of linking to static library earlier in
        search path. [Bug 956908] Removed obsolete references to Rhapsody.
        * unix/configure: autoconf-2.57

2005-01-21  Andreas Kupries  <andreask@activestate.com>

        * generic/tclStubInit.c: Regenerated the stubs support code from the
        * generic/tclDecls.h:    modified tcl.decls (TIP #233, see below).

        * doc/GetTime.3:       Implemented TIP #233, i.e. the
        * generic/tcl.decls:   'Virtualization of Tcl's Sense of Time'.
        * generic/tcl.h:       Declared, implemented, and documented the
        * generic/tclInt.h:    specified new API functions. Moved the
        * unix/tclUnixEvent.c: native (OS) access to time information
        * unix/tclUnixNotfy.c: into standard handler functions. Inserted
        * unix/tclUnixTime.c:  hooks calling on the handlers where native
        * win/tclWinNotify.c:  access was done before, and where scaling
        * win/tclWinTime.c:    between domains (real/virtual) is required.

2005-01-21  Andreas Kupries  <andreask@activestate.com>

        * generic/tclThread.c: Typo police. Fixed some nits
        * generic/tclCmdAH.c:  in header comments of functions.

        [kennykb-numerics-branch]

        * unix/Makefile.in: Updated Makefile to build libtommath on Unix as
        well as Windows. [Bug 1106865]

        * generic/tclTestObj.c (TestbignumobjCmd): Silenced a compiler warning
        about a mismatched 'const'.

        * generic/tclDecls/h: Regen.
        * generic/tclIntDecls.h:
        * generic/tclStubInit.h:

        * tools/fix_tommath_h.tcl: (New file) Script to edit

        that correct an off-by-one error in single-digit multiplication
        (leading to a pointer smash if uncorrected) and change the string
        argument to 'mp_read_radix' from 'char*' to 'const char*'.

        * libtommath/bn_mp_radix_size.c: Local patch to ensure that sufficient
        memory is requested even if the number has a single digit.

        * libtommath/bn_mp_read_radix.c: Local patch to return MP_VAL if the
        input string contains an invalid character.

        * generic/tclObj.c: Added accessor functions for bignums.
        * generic/tclTestObj.c: Added a 'testbignumobj' command to exercise the
        accessor functions for bignums.

        * win/tclWinChan.c (FileCloseProc): Invoke TclpCutFileChannel() to
        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
        I/O finalization stage.

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

        * unix/tcl.m4 (SC_PATH_{TCL,TK}CONFIG): Added code to detect the case
        when the --with-tcl/--with-tk arguments point to the config scripts
        themselves and not their directory. If this is the case, they now
        complain but keep working. [FRQ 951247]
        * unix/configure:       autoconf-2.57

2005-01-10  Joe English  <jenglish@users.sourceforge.net>

        1098829]

2005-01-09  Joe English  <jenglish@users.sourceforge.net>

        * unix/tclUnixThrd.c, unix/tclUnixPort.h: Remove readdir_r() and
        related #ifdeffery (see [Bug 1095909]).
        * unix/tcl.m4, unix/tclConfig.h.in: Don't check for HAVE_READDIR_R.
        * unix/configure: Regenerated.

2005-01-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * library/http/http.tcl (http::mapReply): Significant performance
        enhancement by using [string map] instead of [regsub]/[subst], and

        * generic/tclInt.h, generic/tclPort.h: Move the #include of tclConfig.h
        *first* before any reference to tcl.h so that the build configuration
        is loaded before the first reference to any system headers. Issue
        reported by Art Haas on tcl-core.

2005-01-04  Don Porter  <dgp@users.sourceforge.net>

        * tests/fCmd.test (fCmd-18.10): Added notNetworkFilesystem constraint.
