2004-12-29  Jeff Hobbs  <jeffh@ActiveState.com>

        * win/tcl.m4, win/configure: update MSVC CFLAGS_OPT to -O2, remove -Gs
        (included in -O2) and -GD (outdated). Use "link -lib" instead of "lib"
        binary and remove -YX for MSVC7 portability. Add -fomit-frame-pointer
        for gcc OPT compiles. [Bug 1092952, 1091967] Align LIBS_GUI with Tk
        head needs.

2004-12-29  Kevin B. Kenny  <kennykb@acm.org>

        * generic/tclDate.c: Regen
        * generic/tclGetDate.y (TclDatelex): Fixed a problem where a
        four-digit group with >=2 leading zeroes appeared to be a two-digit
        group, leading to misinterpreting the time 0012 as 1200. [Bug 1090413]
        * library/clock.tcl: Added code to interpret correctly months outside
        the range 01-12 as reduced modulo 12 with a corresponding adjustment
        to the year. [Bug 1092789]
        * tests/clock.test: Added regression test cases for the above two bugs
        * unix/Makefile.in: Added --no-lines to the 'bison' command line to
        * win/Makefile.in: help constrain the number of diffs in a cvs checkin

2004-12-24  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.c:
        * generic/tclCompile.h:
        * generic/tclExecute.c:
        * generic/tclInt.h:
        * generic/tclLiteral.c:
        * generic/tclProc.c:
        Avoid sharing cmdName literals accross namespaces, and generalise
        usage of the TclRegisterNewLiteral macro. [Patch 1090905]

2004-12-20  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.c: moved TclInitCompiledLocals to tclProc.c
        * generic/tclProc.c: new static InitCompiledLocals to allow for a
        single pass over the proc's arguments at proc load time (instead of
        two as previously). TclObjInterpProc() now allocates the
        compiledLocals on the tcl execution stack, using the new
        TclStackAlloc/Free functions.

2004-12-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclInterp.c (Tcl_LimitSetTime, TimeLimitCallback):
        (TclLimitRemoveAllHandlers, TclInitLimitSupport): Set a timer event to
        trigger when the time limit runs out. All the time limit actually does
        is check to see if the time limit has been exceeded, but this is
        enough to fix [Bug 1085023].
        * generic/tclInt.h (struct Interp): Added a field to hold the token
        for the timer event handler associated with the current time limit.
        * generic/tclEvent.c (Tcl_UpdateObjCmd, Tcl_VwaitObjCmd): Add error
        message when limit exceeded.
        * tests/interp.test (interp-34.[89]): Check that time limits handle
        the two cases reported in [Bug 1085023]

        * generic/tclTimer.c (TclCreateAbsoluteTimerHandler): New internal
        function that allows setting a timer handler that will be triggered at
        (or after) a specific time instead of at some number of milliseconds
        in the future. This is a candidate for future exposure via a TIP.

2004-12-15  Miguel Sofer <msofer@users.sf.net>

        * generic/tclBasic.c:
        * generic/tclExecute.c:
        * generic/tclInt.decls:
        * generic/tclIntDecls.h:
        * generic/tclNamesp.c:
        * generic/tclProc.c:
        * generic/tclStubInit.c:
        * generic/tclTest.c: Added two new functions to allocate memory from
        the execution stack (TclStackAlloc, TclStackFree). Added functions
        TclPushStackFrame and TclPopStackFrame that do the work of
        Tcl_PushCallFrame and Tcl_PopCallFrame, but using frames allocated in
        the execution stack - i.e., heap instead of C-stack. The core uses
        these two new functions exclusively; the old ones remain for backwards
        compat, as at least two popular extensions (itcl, xotcl) are known to
        use them.

2004-12-14  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCmdIL.c:
        * generic/tclInt.h:
        * generic/tclProc.c:
        * generic/tclVar.c: changing the isProcCallFrame field of the
        CallFrame struct from a 0/1 field to flags. Should be perfectly
        backwards compatible.

2004-12-14  Don Porter  <dgp@users.sourceforge.net>

        * unix/configure.in: Added special processing to remove "$U" from
        libraries in the LIBOBJS value. This is an auto-make-ism we need to
        avoid. [Bug 1081541]

        * unix/configure: autoconf-2.57

2004-12-13  Don Porter  <dgp@users.sourceforge.net>

        * generic/tcl.h: Restored extern "C" guards so that C++ code sees
        function pointer typedef linkage consistent with earlier Tcl releases.
        [Bug 1082349]

        * generic/tclEncoding.c: Plugged some memory leaks. Thanks to Rolf Ade
        * generic/tclUtil.c:     for reports and testing [Bug 1083082]

2004-12-13  Kevin B. Kenny  <kennykb@acm.org>

        * doc/clock.n: Clarify that the [clock scan] command does not accept
        the full range of ISO8601 point-in-time formats. [Bug 1075433]

2004-12-12  Miguel Sofer <msofer@users.sf.net>

        * generic/tclVar.c (TclArrayObjCmd - ARRAY_NAMES): leaking an object
        [Bug 1084111] - thanks to Rolf Ade.

2004-12-12  Miguel Sofer <msofer@users.sf.net>

        * generic/tclObj.c (TclSetCmdNameObj): special handling for fully
        qualified command names (as in fix [Patch 456668]).

2004-12-11  Miguel Sofer <msofer@users.sf.net>

        * generic/tclInt.h:
        * generic/tclNamesp.c: converting the static function
        GetNamespaceFromObj() to MODULE_SCOPE TclGetNamespaceFromObj().

2004-12-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * tools/tcl.wse.in, unix/tcl.spec, win/README.binary, README:
        * win/configure.in, unix/configure.in, generic/tcl.h:
        Bumped version number to 8.5a3 to distinguish HEAD of CVS development
        from the recent 8.5a2 release.

2004-12-10  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.c (TclInitCompiledLocals):
        * generic/tclCompile.h:
        * generic/tclInt.h:
        * generic/tclProc.c (TclObjInterpProc, TclCreateProc): optimised
        loops that initialise a proc's arguments and compiled local
        variables, removing tests from inner loops.

2004-12-10  Donal K. Fellows  <dkf@users.sf.net>

        * generic/tclInt.h: Move ensemble API decls here from tclNamesp.c

2004-12-09  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclNamesp.c (TclMakeEnsembleCmd, TclSetEnsemble*)
        (TclSetEnsemble*, TclFindEnsemble): Build an internal API for creating
        and manipulating ensembles; they can be deleted using the normal
        command-deletion API.

        * doc/Async.3: Reword for better grammar, better nroff and get the
        flag name right. (Reported by David Welton.)

2004-12-07  Don Porter  <dgp@users.sourceforge.net>

        * tests/unixInit.test (2.1-4): Added constraints so that when a value
        of TCL_LIBRARY is required for process initialization, we skip the
        tests that mess with that value.

2004-12-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        *** 8.5a2 TAGGED FOR RELEASE ***

        * unix/Makefile.in: add library/{tzdata,msgs} to dist target (kbk)

        * doc/foreach.n: Adjust tabs to be friendlier to some HTML
        converters. [Bug 1078760]

2004-12-06  Jeff Hobbs  <jeffh@ActiveState.com>

        * unix/tclUnixNotfy.c (NotifierThreadProc): init numFdBits
        [Bug 1079286]

        * doc/error.n, doc/SaveResult.3, doc/Thread.3: minor nroff typos

2004-12-06  Don Porter  <dgp@users.sourceforge.net>

        * tests/safe.test:      Trim auto_path to improve performance [1080039]

        * tests/msgcat.test:    makeFile/removeFile cleanup [1079117]

2004-12-04  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclEncoding.c:        Different fix for [Bug 1077005].
        * generic/tclEvent.c:   Broke apart TclpSetInitialEncodings() on
        * generic/tclInt.h:     Windows into TclpSetInterfaces(), that is
        * unix/tclUnixInit.c:   fundamentally essential, and the initialization
        * win/tclWinInit.c:     of the system encoding, which is not. Made
        the TclpSetInterfaces call part of TclInitSubsystems so it cannot be
        overlooked.

2004-12-03  Jeff Hobbs  <jeffh@ActiveState.com>

        * changes: updated for 8.5a2 release

2004-12-02  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclUtil.c (TclSetProcessGlobalValue): Handle the case where
        a ProcessGlobalValue might be assigned to itself.

        * generic/tclEncoding.c (MakeFileMap): Correct refcounting errors
        managing values returned by TclPathPart (with refCount of 1!) that led
        to a memory leak. [Bug 1077474].

2004-12-02  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclPathObj.c:  fix and new tests for [Bug 1074671] to ensure
        * tests/fileSystem.test: tilde paths are not returned specially by
        'glob'.

2004-12-02  Kevin B. Kenny  <kennykb@acm.org>

        * win/Makefile.in: Added a 'sed' in the setting of ROOT_DIR_NATIVE to
        compensate for a bug in cygpath (at least version 1.36) that leaves a
        trailing backslash on the end of the converted path.

2004-12-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclInterp.c (Alias,Target,Master): Rewrote these so that the
        aliases that refer to an interpreter are stored in a list and not a
        hashtable (which was only ever a convenience, and forced the use of a
        global mutex to generate keys!) [FRQ 1077210]
        * generic/tclNamesp.c (numNsCreated): Moved into thread-local storage
        to remove a global mutex. [FRQ 1077210]

2004-12-01  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclUtil.c (TclGetProcessGlobalValue): Narrowed the scope of
        mutex locks.

        * generic/tclUtil.c:            Updated Tcl_GetNameOfExecutable() to
        * generic/tclEncoding.c:        make use of a ProcessGlobalValue for
        * generic/tclEvent.c:           storing the executable name. Added
        internal routines Tcl(Get|Set)ObjNameOfExecutable() to access that
        storage in Tcl_Obj, rather than string format.

        * unix/tclUnixFile.c:   Rewrote TclpFindExecutable() to use
        * win/tclWinFile.c:     TclSetObjNameOfExecutable to store the
        executable name it computes.

        * generic/tclInt.h:     Added internal stub entries for
        * generic/tclInt.decls: TclpFindExecutable and
        Tcl(Get|Set)ObjNameOfExecutable.

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

        * generic/tclCmdIL.c:   Retrieve executable name in Tcl_Obj form
        * win/tclWinPipe.c:     instead of string form.

        * unix/tclUnixTest.c:   Update [testfindexecutable] command to use new
        internal interfaces.

        * generic/tclEncoding.c:        Moved TclpSetInitialEncodings() call
        from Tcl_FindExecutable() into TclInitEncodingSubsystem(). This is
        important on Windows where it establishes whether the "ascii" or
        "unicode" set of system routines will be used, and that needs to be
        done earlier to support filesystem operations. [Bug 1077005]

2004-12-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * tests/winDde.test: Rewritten to use tcltest2 features more
        thoroughly (reducing the [catch] count!) and fix the problem with
        winDde-6.1 being out of synch with the implementation.

2004-11-30  Don Porter  <dgp@users.sourceforge.net>

        * library/init.tcl ([unknown]): Restored the save/restore of the
        variables ::errorCode and ::errorInfo. This is needed when the
        [::bgerror] command is auto-loaded (as it is by Tk).

        Patch 976520 reworks several of the details involved with
        startup/initialization of the Tcl library, focused on the activities
        of Tcl_FindExecutable().

        * generic/tclIO.c:      Removed bogus claim in comment that encoding
        "iso8859-1" is "built-in" to Tcl.

        * generic/tclInt.h:     Created a new struct ProcessGlobalValue,
        * generic/tclUtil.c:    routines Tcl(Get|Set)ProcessGlobalValue, and
        function type TclInitProcessGlobalValueProc. Together, these take care
        of the housekeeping for "values" (things that can be held in a
        Tcl_Obj) that are global across a whole process. That is, they are
        shared among multiple threads, and epoch and mutex protection must
        govern the validity of cached copies maintained in each thread.

        * generic/tclNotify.c:  Modified TclInitNotifier() to tolerate being
        called multiple times in the same thread.
        * generic/tclEvent.c:   Dropped the unused argv0 argument to
        TclInitSubsystems(). Removed machinery to unsure only one
        TclInitNotifier() call per thread, now that that is safe. Converted
        Tcl(Get|Set)LibraryPath to use a ProcessGlobalValue, and moved them to
        tclEncoding.c.
        * generic/tclBasic.c:   Updated caller.

        * generic/tclInt.h:     TclpFindExecutable now returns void.
        * unix/tclUnixFile.c:
        * win/tclWinFile.c:
        * win/tclWinPipe.c:

        * generic/tclEncoding.c: Built new encoding search initialization on a
        foundation of ProcessGlobalValues, exposing new routines
        Tcl(Get|Set)EncodingSearchPath. A cache of a map from encoding name to
        directory pathname keeps track of where encodings are available for
        loading. Tcl_FindExecutable greatly simplified into just three
        function calls. The "library path" is now misnamed, as its only
        remaining purpose is as a foundation for the default encoding search
        path.

        * generic/tclInterp.c:  Inlined the initScript that is evaluated by
        Tcl_Init(). Added verification after initScript evaluation that Tcl
        can find its installed *.enc files, and that it has initialized
        [encoding system] in agreement with what the environment expects.
        [tclInit] no longer driven by the value of $::tcl_libPath; it largely
        constructs its own search path now, rather than attempt to share one
        with the encoding system.

        * unix/tclUnixInit.c:   TclpSetInitialEncodings factored so that a new
        * win/tclWinInit.c:     routine TclpGetEncodingNameFromEnvironment can
        reveal that Tcl thinks the [encoding system] should be, even when an
        incomplete encoding search path, or a missing *.enc file won't allow
        that initialization to succeed. TclpInitLibraryPath reworked as an
        initializer of a ProcessGlobalValue.

        * unix/tclUnixTest.c:   Update implementations of [testfindexecutable],
        [testgetdefenc], and [testsetdefenc].

        * tests/unixInit.test:  Corrected tests to operate properly even when
        a value of TCL_LIBRARY is required to find encodings.

        * generic/tclInt.decls: New internal stubs: TclGetEncodingSearchPath,
        TclSetEncodingSearchPath, TclpGetEncodingNameFromEnvironment. These
        are candidates for public exposure by future TIPs.

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

        * generic/tclTest.c:    Updated [testencoding] to use
        * tests/encoding.test:  Tcl(Get|Set)EncodingSearchPath.  Updated tests.

2004-11-30  Kevin B. Kenny  <kennykb@acm.org>

        * library/clock.tcl: Corrected the regular expressions that match a
        time zone to allow for time zones specified as +HH or -HH.
        * tests/clock.test: Added regression test case for the above issue.
        Thanks to Rolf Ade for reporting this issue [http://wiki.tcl.tk/13094]
        * win/tclWinDde.c (Tcl_DdeObjCmd): Corrected a typo that caused a
        compilation failure on VC++.

2004-11-29  Andreas Kupries <andreask@activestate.com>

        * win/Makefile.in (install-libraries): Brought entry '2004-10-26 Don
        Porter (Tcl Modules)' into the windows world, actually the
        win/configure buildsystem. The other windows buildsystems (.vc, .bc)
        still have to be updated as well.

2004-11-26  Andreas Kupries <andreask@activestate.com>

        * win/tclWinDde.c (ExecuteRemoteObject): Removed bogus semicolon found
        at the end of the header for the function definition, terminating it
        early and preventing a compile. This is likely a fix for '2004-11-25
        Donal'. I have to conclude that it is also unknown if the other
        changes to this file actually pass the testsuite. Running testsuite
        ... They don't. winDde-6.1 fails. This is only a message discrepance,
        i.e. not too bad. Leaving resolution of that to Pat and Donal.

2004-11-26  Don Porter  <dgp@users.sourceforge.net>

        * library/auto.tcl (tcl_findLibrary): Made sure the uniquifying
        operations on the search path does not also normalize. [Bug 1072136]

2004-11-26  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * unix/configure.in: Simplify the code to check for correctness of
        strstr, strtoul and strtod.
        * unix/tcl.m4 (SC_TCL_CHECK_BROKEN_FUNC): Split a complex stanza out
        of configure.in into its own function. Also force it to do the right
        thing with cacheing of results of AC_TRY_RUN to deal with issue raised
        in [Patch 1073524]

        * doc/foreach.n: Added simple example. [FRQ 1073334]

2004-11-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclProc.c (TclObjInterpProc):     Make it so that only
        * generic/tclIndexObj.c (Tcl_WrongNumArgs): [proc] instances do
        * tests/indexObj.test (indexObj-5.7):       quoting of their first
        arguments, so keeping [Bug 942757] fixed and making [Bug 1066837] be
        fixed as well. Done with a load of #ifdef-ery because this hack is so
        ugly nobody should keep it around once Itcl's fixed.

2004-11-25  Reinhard Max  <max@suse.de>

        * tests/tcltest.test: The order in which [glob] returns the file names
        is undefined, so tests should not depend on it.

2004-11-25  Zoran Vasiljevic <vasiljevic@users.sf.net>

        * doc/Thread.3:
        * doc/Notifier.3: Added changes from the core-8-4-branch

2004-11-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/dde.n: Synchronized the documentation of the commands with the
        header of the docs and what the package actually does. Thanks to
        Andreas Kupries for spotting this.
        * win/tclWinDde.c (Tcl_DdeObjCmd): Much cleanup of argument parsing
        code.

2004-11-24  David Gravereaux <davygrvy@pobox.com>

        * generic/tclPort.h: Relative include of tclWinPort.h returned as it
        was requiring me set -I$(tcl_root)/win for my extensions that need to
        include tclInt.h and doesn't appear to serve any purpose for windows
        builds.

2004-11-24  Kevin B. Kenny  <kennykb@acm.org>

        * unix/tcl.m4 (SC_ENABLE_THREADS): Corrected bad check for 3-argument
        readdir_r [Bug 1001325].
        * unix/configure: Regenerated.
        * unix/tclUnixNotfy.c: Corrected all uses of 'select' to manage their
        masks using the FD_CLR, FD_ISSET, FD_SET, and FD_ZERO macros rather
        than bit-whacking that failed under Solaris-Sparc-64. [Bug 1071807]
        * win/tclWinInit.c (TclpInitLibraryPath): Removed unused vars 'pathc'
        and 'pathv' that caused compilation problems on VC++ with
        --enable-symbols.

2004-11-24  Don Porter  <dgp@users.sourceforge.net>

        * unix/tcl.m4 (SC_ENABLE_THREADS): Corrected failure to determine the
        number of arguments for readdir_r on SunOS systems. [Bug 1071701]

        * unix/configure:       autoconf-2.57

        * generic/tclCmdIL.c (InfoVarsCmd):     Corrected segfault in new
        * tests/info.test (info-19.6):  trivial matching branch [Bug 1072654]

2004-11-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * tools/man2html.tcl, tools/man2html1.tcl: Update to use Tcl 8.4.
        * tools/man2html2.tcl: Fix broken .SS handling.

2004-11-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * unix/Makefile.in: Add (commented-out) code to integrate tclConfig.h
        into the dependency tree and 'make distclean'. [Bug 1068171]

        * generic/tclResult.c (Tcl_AppendResultVA): Remove call to
        Tcl_GetStringResult to speed up repeated calls to Tcl_AppendResult
        with the side effect that code that wants to access interp->result
        should always call Tcl_GetStringResult first. See [Patch 1041072]
        discussion for more details.

2004-11-22  Mo DeJong  <mdejong@users.sourceforge.net>

        * unix/configure: Regen.
        * unix/tcl.m4 (SC_TCL_64BIT_FLAGS): Define HAVE_TYPE_OFF64_T only when
        off64_t, open64(), and lseek64() are defined. IRIX 5.3 is known to not
        include an open64 function. [Bug 1030465]

2004-11-22  Mo DeJong  <mdejong@users.sourceforge.net>

        * unix/configure: Regen.
        * unix/tcl.m4 (SC_ENABLE_THREADS): Check for a 2 argument version of
        readdir_r that is known to exists under IRIX 5.3.
        * unix/tclUnixThrd.c (TclpReaddir): Use either 2 arg or 3 arg version
        of readdir_r. [Bug 1001325]

2004-11-22  Don Porter  <dgp@users.sourceforge.net>

        * unix/tclUnixInit.c (TclpInitLibraryPath): Purged dead code that used
        * win/tclWinInit.c (TclpInitLibraryPath):  to extend the "library
        path". Search path construction for init.tcl is now done within the
        [tclInit] proc.
        * generic/tclInterp.c:  Restored several directories to the search
        * tests/unixInit.test:  path used to locate init.tcl within [tclInit].
        This change does not restore any directories to the encoding search
        path, so should still avoid the price of an unreasonably large number
        of filesystem accesses during encoding initialization at startup
        [Bug 976438]

2004-11-22  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclPathObj.c: fix and new test for [Bug 1043129] in the
        * tests/fileSystem.test: treatment of backslashes in file join on
        Windows.

2004-11-21  Don Porter  <dgp@users.sourceforge.net>

        * doc/AddErrInfo.3:     Typo corrections (Thanks Daniel South).

        * doc/error.n:          the Tcl_*InterpState routines, and the

2004-11-19  Daniel Steffen  <das@users.sourceforge.net>

        * macosx/Makefile:
        * unix/configure.in:
        * unix/tclUnixInit.c (MacOSXGetLibraryPath): changed detection of tcl
        framework build when determining tclLibPath from overloaded
        TCL_LIBRARY to configuration define TCL_FRAMEWORK. [Bug 1068088]

        * unix/configure: autoconf-2.57
        * unix/tclConfig.h.in: autoheader-2.57

2004-11-18  Don Porter  <dgp@users.sourceforge.net>

        * doc/SaveResult.3:     Documentation for Tcl_*InterpState (TIP 226).

        * generic/tclEvent.c (HandleBgErrors):  Simplified program flow.

        * tests/basic.test:     Updated functional (not testing) uses of
        * tests/io.test:        [bgerror] to make use of [interp bgerror].
        * tests/socket.test:
        * tests/timer.test:

        * tests/interp.test (interp-36.*):      [interp bgerror] tests.

        * generic/tclInterp.c:  Corrected [interp bgerror] error messages.

2004-11-18  Reinhard Max  <max@suse.de>

        * unix/tcl.m4 (SC_CONFIG_MANPAGES): Applied an improved version of
        * unix/configure.in:                [Patch 996085], that introduces
        * unix/Makefile.in:                 --enable-man-suffix.

        * unix/installManPage:              added
        * unix/mkLinks.tcl:                 removed
        * unix/mkLinks:                     removed
        * unix/configure:                   generated

        * unix/Makefile.in:                 Don't install tclConfig.h .

2004-11-17  Don Porter  <dgp@users.sourceforge.net>

        * unix/configure.in: The change below reveals that the public data
        type Tcl_StatBuf relies on config information. For now, disabled the
        use of the tclConfig.h file until its full impact on Tcl's interface
        can be assessed.

        * unix/configure:       autoconf-2.57

        * generic/tcl.h:        Moved the #include "tclConfig.h" out of
        * generic/tclInt.h:     tcl.h.  The config settings are not part of
        * generic/tclPort.:     the public interface, and having it there
        breaks compiled against uninstalled Tcl and extensions using
        autoconf-2.5*.

2004-11-16  Jeff Hobbs  <jeffh@ActiveState.com>

        * unix/tclUnixChan.c (TtySetOptionProc): fixed crash configuring
        -ttycontrol on a channel. [Bug 1067708]

2004-11-16  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclIOUtil.c (TclFSEpochOk): There were two code paths via
        which the thread copy of filesystemEpoch could be synched with the
        master copy, but only one kept the filesystem list cache up to date.
        Fix routes everything through a single code path. [Bug 1035775].

2004-11-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * unix/tcl.m4 (SC_CONFIG_CFLAGS): Stop architecture flags to 'ld' from
        getting lost when [load] is disabled. [Bug 1016796]

2004-11-16  Daniel Steffen  <das@users.sourceforge.net>

        * generic/tcl.h:
        * unix/configure.in: changed HAVE_CONFIG_H to HAVE_TCL_CONFIG_H.

        * unix/configure: autoconf-2.57

2004-11-15  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclInt.h: Added comment warning that the old ERR_IN_PROGRESS
        and ERROR_CODE_SET flag values should not be re-used for the sake of
        those extensions that have accessed them.

        * generic/tclCmdMZ.c (Tcl_TraceObjCmd): Fixed Bug 1065378 which failed
        * tests/trace.test (trace-33.1):        to permit a variable trace
        created with [trace variable] to be destroyed with [trace remove].
        Thanks to Keith Vetter for the report.

2004-11-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/tclvars.n: Added section to documentation on global variables
        that are specific to tclsh and wish. [Patch 1065732]

2004-11-12  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclEncoding.c (TableFromUtfProc): correct crash condition
        when TCL_UTF_MAX == 6. [Bug 1004065]

2004-11-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/interp.n: Basic documentation of the TIP#221 API.

2004-11-12  Don Porter  <dgp@users.sourceforge.net>

        TIP #221 IMPLEMENTATION
        * generic/tclBasic.c:   Define [::tcl::Bgerror] in new interps.
        * generic/tclEvent.c:   Update Tcl_BackgroundError to make use of the
                                registered [interp bgerror] command.
        * generic/tclInterp.c:  New [interp bgerror] subcommand.
        * tests/interp.test:    syntax tests updated.

        TIP #226 IMPLEMENTATION
        * generic/tcl.decls:    Stubs for Tcl_(Save|Restore|Discard)InterpState
        * generic/tcl.h:        New public opaque type, Tcl_InterpState.
        * generic/tclInt.h:     Drop old private declarations. Add
                                Tcl(Get|Set)BgErrorHandler
        * generic/tclResult.c:  Tcl_*InterpState implementations.
        * generic/tclDictObj.c: Update callers.
        * generic/tclIOGT.c:
        * generic/tclTrace.c:

        TIP #227 IMPLEMENTATION
        * generic/tcl.decls:    Stubs for Tcl_(Get|Set)ReturnOptions.
        * generic/tclInt.h:     Drop old private declarations.
        * generic/tclResult.c:  Tcl_*ReturnOptions implementations.
        * generic/tclCmdAH.c:   Update callers.
        * generic/tclMain.c:

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

        * unix/tclAppInit.c:    Removed tclConfig.h #include, now that tcl.h
                                takes care of it for us.

        * generic/tclInt.h:     Moved verification of ptrdiff_t typedef from
        * generic/tclExecute.c: multiple .c files into one common header where
        * generic/tclVar.c:     it is verifiably after tclConfig.h inclusion.

2004-11-12  Daniel Steffen  <das@users.sourceforge.net>

        * generic/tcl.h:
        * generic/tclInt.h:
        * unix/Makefile.in: include tclConfig.h from tcl.h and install it as a
        public header. Normalized compiler include path order to
        -I${BUILD_DIR} -I${UNIX_DIR} -I${GENERIC_DIR}.

        * unix/dltest/Makefile.in: add ${BUILD_DIR}/.. to include path to pick
        up tclConfig.h.

        * unix/tclUnixInit.c: moved check for HAVE_CFBUNDLE define after
        #include "tclInt.h" to ensure tclConfig.h has been included.

2004-11-12  Reinhard Max  <max@suse.de>

        * unix/config.h.in:
        * unix/tclConfig.h.in:  renamed

        * unix/Makefile.in:     Completed support for config header,
        * unix/configure.in:    fixed building outside of the unix dir,
        * unix/tclAppinit.c:    and reflected the name change of config.h.
        * generic/tclInt.h:

        * unix/configure:       generated

2004-11-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * unix/config.h.in:     Allow configure to put all the C #defs into
        * unix/configure.in:    a file (called config.h) so that Unix builds
        * unix/tcl.m4:          now take far fewer lines of scrollback to
        * unix/Makefile.in:     proceed (making it less likely that any errors
        * generic/tclInt.h:     or warnings will get missed).
        * unix/tclAppInit.c:    Part of the TIP#34 upgrades.

        * unix/tcl.m4, unix/tclUnixPort.h: Check for pthread_attr_get_np in
        <pthread.h> before forcing the use of <pthread_np.h> to make things
        work on NetBSD 2.0. [Bug 1064882]

        * doc/binary.n, doc/upvar.n: More minor fixes.

2004-11-12  Daniel Steffen  <das@users.sourceforge.net>

        * doc/CrtChannel.3:
        * doc/Interp.3:
        * doc/Limit.3:
        * doc/binary.n:
        * doc/dict.n:
        * doc/tm.n:
        * doc/upvar.n: fixed *roff errors uncovered by running 'make html'.

        * tools/tcltk-man2html.tcl: added faked support for bullet point
        lists, i.e. *nroff ".IP \(bu" syntax.

2004-11-11  Daniel Steffen  <das@users.sourceforge.net>

        * tests/fCmd.test:
        * unix/tclUnixFCmd.c (TraverseUnixTree): added option to rewind() the
        readdir() loop whenever the source hierarchy has been modified by
        traverseProc (e.g. by deleting files); this is required to ensure
        complete traversal of the source hierarchy on certain filesystems like
        HFS+. Added test for failing recursive delete on Mac OS X that was due
        to this. [Bug 1034337]

        * generic/tclListObj.c (Tcl_ListObjReplace): use memmove() instead of
        manual copy loop to shift list elements. Decreases time spent in
        Tcl_ListObjReplace() from 5.2% to 1.7% of overall runtime of tclbench
        on a ppc 7455 (i.e. 200% speed increase). [Patch 1064243]

        * generic/tclHash.c: hoisted some constant pointer dereferences out of
        loops to eliminate redundant loads that the gcc optimizer didn't deal
        with. Decreases time spend in Tcl_FindHashEntry() by 10% over a full
        run of the tcl testuite on a ppc 7455. [Patch 1064243]

        * tests/fileName.test:
        * tests/fileSystem.test:
        * tests/io.test:
        * tests/msgcat.test:
        * tests/tcltest.test:
        * tests/unixInit.test: fixed bugs causing failures when running tests
        with -tmpdir arg not set to working dir.

        * macosx/Makefile: corrected path to html help inside framework.
        Prevent parallel make from building several targets at the same time.

        * macosx/tclMacOSXFCmd.c (struct fileinfobuf): force struct to be
        packed to prevent failures when builing with -malign=natural.

2004-11-10  Andreas Kupries <andreask@activestate.com>

        * unix/tclUnixChan.c: [Bug 727786]. Exterminated the code marked
        DEPRECATED. This code has not been used in over a year now, and we
        have no complaints.

2004-11-08  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinPipe.c: The pipe channel driver now respects the -blocking
        option when closing is the same way the UNIX side works. This is to
        avoid a hung shell when exiting due to open pipes that refuse to close
        in a graceful manner.
        * doc/open.n: Added a note about -blocking 0 and lack of exit status
        as it had never been documented. [Bug 947693]

        ***POTENTIAL INCOMPATIBILITY***

        Scripts that use async pipes on windows, must (like the UNIX side) set
        -blocking to 1 before calling [close] to receive the exit status.

2004-11-07  David Gravereaux <davygrvy@pobox.com>

        * tests/winFile.test: added contraint to winFile-4.0 to prevent it
        being run on NT4 [Bug 981829]

2004-11-05  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * tests/reg.test: Major reorganization so that this file is much
        easier for a normal Tcl maintainer to comprehend. The test flags are
        still very cryptic, but they appear to have to be that way. The number
        of skipped tests has increased, but now the skipped tests have much
        more meaningful content.

        * tests/tm.test (genpaths): Add a [file normalize] so we pick up
        Windows drive letters, etc. [Bug 1053568]

2004-11-04  Don Porter  <dgp@users.sourceforge.net>

        * changes:      Updates toward an 8.5a2 release.

2004-11-03  Kevin B. Kenny  <kennykb@acm.org>

        * library/clock.tcl (FreeScan): Fixed a bug where scanning "Monday"
        with a base time other than midnight incorrectly carried the base time
        forward.

        * test/clock.test (clock-33.{5,5a}): Made the test failure more
        informative.

        * tests/clock.test (clock-34.{28,44,45,46}): Removed 'knownBug'
        constraints from tests that no longer fail.

        Thanks to Don Porter for reporting these.

2004-11-03  David Gravereaux <davygrvy@pobox.com>

        * generic/tcl.h:                Moved the preprocessor logic
        * generic/tclDecls.h:           from tclInt.h of setting the
        * generic/tclInt.h:             TCL_STORAGE_CLASS macro to the
        * generic/tclIntDecls.h:        tcl*Decls.h files now that no
        * generic/tclIntPlatDecls.h:    use of EXTERN is left in tclInt.h.
        * generic/tclPlatDecls.h:       Proto for Tcl_Main moved in tcl.h
        * win/tclWinPort.h:             to prior the inclusion of the Stubs
        headers as they are now resetting TCL_STORAGE_CLASS. Removed
        extraineous reset from tclWinPort.h. [Patch 1055668]

        * generic/tclCompile.h: Removed extrainious reset of TCL_STORAGE_CLASS
        missed in my last edit.

2004-11-03  Don Porter  <dgp@users.sourceforge.net>

        * library/init.tcl ([unknown]): Corrections to the 2004-10-25 mods to
        Aunt ??? in [unknown]. Flaws revealed by Itcl test suite, which still
        apparently relies on this brokenness. Also added comment suggesting
        the error message that any code using this hack *ought* to receive in
        reply.

        * generic/tclTrace.c (TclCallVarTraces):  Improved ability to debug
        * tests/incr-old.test (incr-old-2.6):     errors during variable
        * tests/incr.test (incr-{1,2}.28):        traces by preserving the
        * tests/set.test (set-{2,4}.4):           -errorinfo data.
        * tests/trace.test (trace-33.1):          [Bug 527164]

2004-11-02  David Gravereaux <davygrvy@pobox.com>

        * generic/tclInt.h: added a check for #ifdef __cplusplus around the
        #define of MODULE_SCOPE. About the only time it would be problem is
        when someone is statically linking to Tcl and accessing internals from
        a C++ file and has name mangling issues from the lack of "C" after
        'extern' [Patch 1055668].
        * generic/tclCompile.h: Exchanged use of the EXTERN macro to the new
        MODULE_SCOPE macro. Lowered exported internals count by 35. [Patch
        1055668]
        * win/tclWinInt.h:
        * win/tclWinPort.h: exported internals dropped by a count of 14.
        * generic/tclFileSystem.h: Added use of MODULE_SCOPE on protos.
        * generic/tclRegexp.h: manipulating TCL_STORAGE_CLASS unnecessary.

2004-11-02  Don Porter  <dgp@users.sourceforge.net>

        * library/tcltest/tcltest.tcl:          Corrected some misleading
        * tests/tcltest.test (tcltest-26.1,2):  displays of ::errorInfo and
        ::errorCode information when the -setup, -body, and/or -cleanup scripts
        return an unexpected return code. Thanks to Robert Seeger for the fix.
        [RFE 1017151].

2004-11-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclExecute.c (TclExecuteByteCode): Improved version of the
        NaN fix from Miguel Sofer. [Bug 761471]

2004-11-02  Kevin Kenny  <kennykb@acm.org>

        * library/tzdata/America/Cuiaba: Change to DST rules for

        [ftp://elsie.nci.nih.gov/pub/tzdata2004g.tar.gz]

        * tools/tclZIC.tcl: Updated to be compatible with recent changes in

        * win/tclWinFile.c: Simplify TclpUtime to use Tcl_FSGetNativePath, and
        add comments.

2004-11-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclInt.h: Change uses of EXTERN to MODULE_SCOPE (defined in
        this file too to be 'extern' if not overridden) as nothing declared in
        tclInt.h is supposed to be visible outside the Tcl core. If there *is*
        anything that extensions are actually using, we can open this up later
        on. [Patch 1055668]

        * doc/CrtChannel.3 (Tcl_GetChannelMode): Add synopsis. [Bug 1058446]

2004-11-01  Kevin B. Kenny  <kennykb@acm.org>

        * win/tclWinFile.c (FromCTime, TclpUtime): Replaced a call to the
        Posix 'utime' function with calls to Windows-API equivalents, to avoid
        a bug where the VC++ versions misconvert times across a Daylight
        Saving Time boundary. [Bug 926106]
        * win/tclWinInt.h (TclWinProcs):
        * win/tclWin32Dll.c (asciiProcs, unicodeProcs): Removed now-unused
        reference to 'utime'.
        * tests/cmdAH.test (cmdAH-24.12): Added test case for the above bug.

2004-11-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclExecute.c (TclExecuteByteCode): Make INST_EQ and friends
        handle NaN correctly in all cases. [Bug 761471]

        * generic/tclNamesp.c (NamespaceInscopeCmd): Make the error message
        generation the same as in NamespaceEvalCmd().
        (Tcl_Import): Rationalized to use Tcl_EvalObjv().

2004-10-31  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * tests/io.test (io-40.3): Convert umask2 test constraint into a form
        that most people will be able to satisfy.

        * tests/cmdAH.test (cmdAH-8.45): Removed broken test constraint. It
        didn't do what it was intended to do, and it implied the other correct
        constraint. [Bug 1053908]

        * generic/tclCmdIL.c (InfoGlobalsCmd):
        * tests/info.test (info-8.4): Strip leading global-namespace
        specifiers from the pattern argument. [Bug 1057461]

2004-10-30  Kevin Kenny  <kennykb@acm.org>

        * generic/clock.c: Replaced WIN32 macro with __WIN32__. [Bug 1054357].
        Thanks to David Gravereaux for the patch.
        * win/tclWinFile.c: Removed a long-standing bug that causes incorrect
        conversion between file time and UTC time if the file time is recorded
        in a different Daylight Saving Time status than the current one. [Bug
        926106]

2004-10-29  Don Porter  <dgp@users.sourceforge.net>

        * library/tcltest/tcltest.tcl:  Correct reaction to errors in the
        obsolete processCmdLineArgsHook.        [Bug 1055673]
        * library/tcltest/pkgIndex.tcl: Bump to tcltest 2.2.7
        * unix/Makefile.in:
        * tests/all.tcl:        Update to use [tcltest::configure].

2004-10-29  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * library/tm.tcl (::tcl::tm::*): Use the core proc engine to generate
        the wrong-num-args error messages for the path ensemble.

        Ensembles can now (sometimes) rewrite the error messages of their
        subcommands so they appear more like the arguments that the user
        passed to the ensemble. Below is a description of changes involved in
        doing this.

        * tests/namespace.test (namespace-50.*): Tests of ensemble subcommand
        error message rewriting.
        * generic/tclProc.c (TclObjInterpProc): Make procedures implement
        their wrong-num-args message using Tcl_WrongNumArgs instead of
        something baked-at-home.
        * generic/tclNamesp.c (TclIsEnsemble, NsEnsembleImplementationCmd):
        Added test of ensemble-hood (available to rest of core) and made
        ensembles set up the rewriting for Tcl_WrongNumArgs to take advantage
        of.
        * generic/tclInt.h (Interp.ensembleRewrite): Extra fields.
        * generic/tclIndexObj.c (Tcl_WrongNumArgs): Add knowledge of what is
        going on in ensembles' command rewriting so this command can generate
        the right error message itself.
        * generic/tclBasic.c (Tcl_CreateInterp, TclEvalObjvInternal): Added
        code to initialize (as empty) the rewriting fields and reset them when
        we leak outside an ensemble implementation.

2004-10-28  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c (INST_START_CMD):
        * tests/execute.test (execute-8.3): fix for execution stack corruption
        [Bug 1055676]. Credit dgp for detective work and fix.

2004-10-27  Don Porter  <dgp@users.sourceforge.net>

        * tests/socket.test (socket-13.1):      Balanced [makeFile] and
        [removeFile] commands.

        * tests/clock.test:     Correct duplicate test names.
        * tests/namespace.test:
        * tests/string.test:
        * tests/io.test (io-50.4):      Use namespace variables.

2004-10-27  David Gravereaux <davygrvy@pobox.com>

        * generic/tclInt.decls:   The following 9 functions were moved from
        * generic/tclInt.h:       tclInt.h to the private/int Stubs table for
        * generic/tclIntDecls.h:  use by the test suite. As tclTest.obj is
        * generic/tclStubInit.c:  linked to the shell, these functions need
        "blessed" status so as to always be exported from the library. Being
        placed in the Stubs table guarantees this [Bug 1054748]:
                TclpObjRemoveDirectory, TclpObjCopyDirectory,
                TclpObjCreateDirectory, TclpObjDeleteFile,
                TclpObjCopyFile,        TclpObjRenameFile,
                TclpObjStat,            TclpObjAccess,
                TclpOpenFileChannel

        * tests/registry.test:  Fixed test files to load the correct
        * tests/winDde.test:    registry and dde packages by using the info
        * win/Makefile.in:      from makefiles to tell tcltest where to load
        * win/makefile.vc:      them from. This avoids grabbing the wrong
        package from $auto_path which might be the install point rather than
        the dev location. Kudos to Jennifer Hom for adding -load and
        -loadfile to the tcltest package. [Bug 926088]

        * win/tclWinThrd.c (TclFinalizeLock): release the critical section
        before deleting it. [Bug 731778]

        * generic/tcl.h: Removed the file level 'extern "C" {' and the
        coresponding closing block as it serves no purpose given that all the
        function prototypes have the proper extern usage already.

        * unix/tclAppInit.c:    When built as tcltest, TclThread_Init was
        * win/tclAppInit.c:     getting called twice. First by Tcltest_Init,
        then again in Tcl_AppInit. The call from Tcl_AppInit is now removed.

2004-10-27  Andreas Kupries <andreask@activestate.com>

        * tests/tm.test:  Expanded on the testsuite entered by Donal.
        * library/tm.tcl: Even found bugs, these have been corrected.

2004-10-26  Kevin Kenny <kennykb@acm.org>

        * tests/format.test (format-19.1): Additional regression test for [Bug
        868489].

2004-10-27  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/*.n: Many small general documentation fixes.

2004-10-26  David Gravereaux <davygrvy@pobox.com>

        * generic/tclPipe.c (TclCleanupChildren): bad cast of resolvedPid
        caused PIDs on win95 to go negative. winpipe-4.2 brought this to the
        surface. Fixed with sprintf in place of TclFormatInt. Thanks to hgiese
        [Patch 767676]

2004-10-26  Andreas Kupries <andreask@activestate.com>

        * library/tm.tcl (::tcl::tm::Defaults): Added a second [file dirname]
        around the location of the executable. This fixes [Bug 1038705].
        Instable of a bogus "foo/bin/lib" we now have the correct "foo/lib" as
        a base path for modules.

2004-10-26  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclParse.c (Tcl_SubstObj):    Fix for failed subst-12.3 test
        * tests/subst.test (subst-12.3-5):      More tests for Bug 1036649.

        * unix/Makefile.in (install-libraries): Updated the installation of
        the http, msgcat, and tcltest packages to install as Tcl Modules on
        Unix systems. Other platform Makefiles still need updating. [Patch
        1054370]

        * tests/basic.test:     Added missing constraints.
        * tests/compile.test:
        * tests/fileSystem.test:

        * tests/init.test (init-2.8):   Updated to not rely on http package.

2004-10-26  Miguel Sofer <msofer@users.sf.net>

        * generic/tclInt.h:
        * generic/tclVar.c: removed more direct references to the VAR flags,
        replaced with access macros.

2004-10-26  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/expr.n: Clarified that non-num/non-bool literals require
        quoting. [Bug 1027849]. Also listed booleans as acceptable values.

2004-10-26  Kevin B. Kenny <kennykb@acm.org>

        * library/clock.tcl (FreeScan): Fixed a bug that caused relative days
        of the week in free-form [clock scan] to be evaluated in the wrong
        time zone.
        * tests/clock.test (clock-31.[456]): Made sure that there isn't an
        env(TZ) or env(TCL_TZ) lying around that will override the time zone
        that we're trying to establish with the simulated registry.
        Both problems reported as [Bug 1054101].

2004-10-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/string.n (map): Rewrote to clarify that we don't just map single
        characters. [Bug 1048005]
        * doc/info.n (procs): Clarified that the pattern argument may have
        namespace separators in it. [Bug 1047928]

        * tests/cmdAH.test (cmdAH-8.45): Simplify in the hope that the reasons
        for [Bug 1053908] will become clearer.

2004-10-25  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclExecute.c (IllegalExprOperandType,TclExecuteByteCode):
        Removed several DECACHE_INFO/CACHE_INFO pairs that are no longer
        needed for protection because routines like Tcl_SetErrorCode() and
        Tcl_AddErrorInfo() can no longer re-enter bytecode execution.

        * generic/tclResult.c (TclProcessReturn): Bug fix. Be sure that a
        missing -errorinfo option when code == TCL_ERROR causes the errorInfo
        field to get reset.

        * tests/thread.test (thread-4.4): Test depended on a ::errorInfo value
        initialized to "". Added code to test to setup that requirement.

        * library/auto.tcl:     Purged Tcl's script library of all
        * library/clock.tcl:    remaining references to global vars
        * library/init.tcl:     ::errorInfo and ::errorCode.

        * generic/tclMain.c (Tcl_Main): Updated to make use of
        TclGetReturnOptions instead of ::errorInfo variable.

        * generic/tclInterp.c (tclInit): Bug fix. Access dict variables with
        [dict get], not array syntax.

2004-10-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * tests/tm.test: Rewrote the tests to actually perform syntax checks
        on the public API. Added a new test (currently failing) to indicate
        that the test suite is not complete yet.
        * library/tm.tcl (path): Rewrote to turn this command into an ensemble
        to make it faster and simpler.

2004-10-24  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCmdIL.c:
        * generic/tclExecute.c:
        * generic/tclInt.h:
        * generic/tclTrace.c: defined new macros to get/set the flags of
        variables. The only files that still access the flag values directly
        are tclCompCmds.c, tclCompile.c, tclProc.c and tclVar.c

2004-10-24  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclBasic.c (Tcl_LogCommandInfo,Tcl_AddObjErrorInfo): Shift
        the initialization of errorCode to NONE to more central location.

        * generic/tclEvent.c (BgError,Tcl_BackgroundError,HandleBgErrors):
        Rewrite to build on the new TclGet/SetReturnOptions routines.

        * generic/tclResult.c (TclGetReturnOptions): Add call to
        Tcl_AddObjErrorInfo to be sure error fields are initialized.

        * generic/tclResult.c (TclTransferResult): Rewrite to build on the new
        TclGet/SetReturnOptions routines.

2004-10-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/tm.n: Tightened up the documentation.
        * tests/tm.test: Created (with partially dummy content) so TIP#189 can
        be marked Final.

        * generic/tclNamesp.c (NsEnsembleImplementationCmd): Make ensembles
        cut their implementations out of error traces. This is the right thing
        to do more often than not.

2004-10-22  Kevin B. Kenny  <kennykb@acm.org>

        * library/clock.tcl: Fixed a typo where the fallback time zone became
        ::localtime instead of :localtime. Fixed a bug where time zone names
        containing hyphens could not be loaded.
        * tests/clock.test: Added regression test cases that covers both bugs.
        Thanks to Todd M. Helfter <tmh@jumpgate.itsp.purdue.edu> for finding
        these bugs.

2004-10-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclExecute.c (TclCompEvalObj, Tcl_ExprObj):
        * generic/tclProc.c (TclProcCompileProc): Always call object
        freeIntRepProc's in the same way.

2004-10-22  Miguel Sofer <msofer@users.sf.net>

        * generic/tclVar.c: fixed bug in commit of 2004-07-23, which was
        causing a leak of Proc structures and failure of compile-12.1. Two
        lines were 'zombies' from the previous way localVarNames worked.
        Credit dgp for finding this.

2004-10-21  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclInt.h (Interp):
        * generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp):
        * generic/tclResult.c (GetKeys,ReleaseKeys,etc.): Moved the key values
        of the return options dictionary out of private fields of the Interp
        struct and into thread-static values managed in tclResult.c.

        * generic/tclCmdAH.c (Tcl_CatchObjCmd, Tcl_ErrorObjCmd): Updated to
        call the new TclGet/SetReturnOptions routines to do much of their
        work.

        * generic/tclInt.h (TclGetReturnOptions,TclSetReturnOptions):
        * generic/tclResult.c (TclGetReturnOptions,TclSetReturnOptions): New
        utility routines to get/set the return options of an interp. Intent is
        that these routines will be converted to public routines after TIP
        approval.

        * generic/tclCmdMZ.c (TclProcessReturn,TclMergeReturnOptions):
        * generic/tclResult.c (TclProcessReturn,TclMergeReturnOptions): Move
        internal utility routines from tclCmdMZ.c to tclResult.c.

        * generic/tclBasic.c (Tcl_CreateInterp, Tcl_DeleteInterp):
        * generic/tclResult.c (TclTransferResult): Rework so that
        iPtr->returnOpts can be NULL when there are no special options.

        * generic/tclResult.c (TclRestoreInterpState): Plug potential memory
        leak.

2004-10-21  Kevin B. Kenny  <kennykb@acm.org>

        * generic/tclBasic.c: Various changes to [clock format] that,
        * generic/tclClock.c: together, make it roughly twice as fast
        * generic/tclInt.h:   while all tests in the test suite
        * library/clock.tcl:  continue to pass.

2004-10-20  Andreas Kupries <andreask@activestate.com>

        * win/Makefile.in (install-msgs):   Fixed a problem with the
        * win/Makefile.in (install-tzdata): installation of timezone data and
        message catalogs. They used the installed tcl library directory, not
        the source library. Before it was installed. Switched to source lib
        dir. Thanks to Kevin for the help in figuring this out.

2004-10-20  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclThreadTest.c (ThreadEventProc): Corrected subtle bug
        where the returned (char *) from Tcl_GetStringResult(interp) continued
        to be used without copying or refcounting, while activity on the
        interp continued. That's not safe, and recent changes demonstrated the
        lack of safety with failing tests thread-4.3 and thread-4.5.

2004-10-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclDictObj.c (DictWithCmd): Make sure all paths (that are
        not themselves error paths) do not lose the result code.

2004-10-19  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclInt.h (Tcl*InterpState):           New internal routines
        * generic/tclResult.c (Tcl*InterpState):        TclSaveInterpState,
        TclRestoreInterpState, and TclDiscardInterpState are superior
        replacements for Tcl_(Save|Restore|Discard)Result. Intent is that
        these routines will be converted to public routines after TIP
        approval. Interfaces for these routines were shamelessly stolen from
        Itcl.

        * generic/tclBasic.c (TclEvalObjvInternal):
        * generic/tclDictObj.c (DictUpdateCmd, DictWithCmd):
        * generic/tclIOGT.c (ExecuteCallback):
        * generic/tclTrace.c (Trace*Proc,TclCheck*Traces,TclCallVarTraces):
        Callers of Tcl_*Result updated to call the new routines. The calls
        were relocated in several cases to perform save/restore operations
        only when needed.

        * generic/tclEvent.c (HandleBgErrors):
        * generic/tclFCmd.c (CopyRenameOneFile): Calls to Tcl_*Result that
        were eliminated because they appeared to serve no useful purpose,
        typically saving/restoring an error message, only to throw it away.

2004-10-18  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp):
        * generic/tclCmdAH.c (Tcl_CatchObjCmd):
        * generic/tclCmdMZ.c (TclMergeReturnOptions,TclProcessReturn):
        * generic/tclCompCmds.c (TclCompileReturnCmd):
        * generic/tclExecute.c (TclCompEvalObj):
        * generic/tclInt.h (Interp):
        * generic/tclProc.c (TclUpdateReturnInfo): Place primary storage of
        the -level and -code information in private fields of the Interp
        struct, rather than in a DictObj. This should significantly improve
        performance of TclUpdateReturnInfo.

2004-10-17  Miguel Sofer <msofer@users.sf.net>

        * generic/tclResult.c: removed unused variable [Bug 1048588]. Thanks
        to Daniel South.

2004-10-15  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclCmdMZ.c (TclProcessReturn):        Now that primary
        * generic/tclProc.c (TclUpdateReturnInfo):      storage for the
        errorInfo and errorCode values are internal fields, we can set them at
        the time of the [return] command, and not have to wait until the
        specified number of "-level"s have popped.

        * generic/tclBasic.c (Tcl_CreateInterp, Tcl_DeleteInterp)
        (TclEvalObjvInternal, Tcl_LogCommandInfo, TclAddObjErrorInfo):
        * generic/tclCmdAH.c (Tcl_CatchObjCmd):
        * generic/tclEvent.c (BgError, ErrAssocData, Tcl_BackgroundError)
        (HandleBgErrors, BgErrorDeleteProc):
        * generic/tclExecute.c (TclCreateExecEnv, TclDeleteExecEnv):
        * generic/tclIOUtil.c (comments only):
        * generic/tclInt.h (ExecEnv,Interp, ERR_IN_PROGRESS):
        * generic/tclInterp.c ([tclInit]):
        * generic/tclMain.c (comments only):
        * generic/tclNamesp.c (Tcl_CreateNamespace, Tcl_DeleteNamespace)
        (TclTeardownNamespace):
        * generic/tclProc.c (TclUpdateReturnInfo):
        * generic/tclResult.c (Tcl_ResetResult, TclTransferResult):
        * generic/tclTrace.c (CallVarTraces):
        Reworked management of the "errorInfo" data of an interp. That
        information is now primarily stored in a new private (Tcl_Obj *) field
        of the Interp struct, rather than using a global variable ::errorInfo
        as the primary storage. The ERR_IN_PROGRESS flag bit value is no
        longer required to manage the value in its new location, and is
        removed. Variable traces are established to support compatibility for
        any code expecting the ::errorInfo variable to hold the information.

        ***POTENTIAL INCOMPATIBILITY***
        Code that sets traces on the ::errorInfo variable may notice a
        difference in timing of the firing of those traces. Code that uses the
        value ERR_IN_PROGRESS.

        TIP#217 IMPLEMENTATION

        * generic/tclCmdIL.c (Tcl_LsortObjCmd): Add -indices option from James
        Salsman. [Patch 1017532]

        * generic/tclUtil.c (TclMatchIsTrivial): Detect degenerate cases of
        glob matching that let us avoid scanning through hash tables.
        * generic/tclCmdIL.c (InfoCommandsCmd, InfoGlobalsCmd, InfoProcsCmd):
        (InfoVarsCmd): Use this to speed up some [info] subcommands.

        TIP#201 AND TIP#212 IMPLEMENTATIONS

        * doc/dict.n, doc/expr.n: Documentation for new functionality.
        * tests/expr.test: Basic tests of 'in' and 'ni' behaviour.
        * tests/dict.test (dict-21.*,dict-22.*): Tests for [dict update] and
        [dict with].
        * generic/tclExecute.c (TclExecuteByteCode): Implementation of the
        INST_LIST_IN and INST_LIST_NOT_IN bytecodes.
        * generic/tclParseExpr.c (GetLexeme): Parse the 'in' and 'ni'
        operators for TIP#201.
        * generic/tclDictObj.c (DictUpdateCmd,DictWithCmd): Core of
        implementation of TIP#212; docs and tests still to do...

2004-10-07  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclTest.c (TestsetobjerrorcodeCmd):  Simplified.

2004-10-07  Vince Darley  <vincentdarley@users.sourceforge.net>

        * win/tclWinFile.c:
        * tests/fileName.test:
        * tests/winFCmd.test: code reorganization for better generic/platform
        code splitting [Bug 925620] removing the need for several #ifdef's,
        and tests and fix for an unreported Windows glob problem ('glob -dir
        C: -tails *').

2004-10-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * *.3: Convert CONST to const and VOID to void so we document how
        people should actually use the Tcl API and not the compatability hacks
        that it has to have.

        * doc/man.macros, *.3: Update .AS macro so it can know how wide to
        make the third column of the argument list. Update documentation for C
        API (only users) to take advantage of this.

        * doc/FileSystem.3: Formatting fixes for greater documentation
        clarity.

2004-10-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclFileName.c (DoGlob, TclGlob): Stop messy sharing of
        interpreter result and instead use a private object for collecting the
        result of the glob. This simplifies TclGlob quite a lot.
        * generic/tclIOUtil.c (Tcl_FSMatchInDirectory): Simplify by removing
        some nesting. Also standardize variable names.
        (FsAddMountsToGlobResult): Force updates to the list to be done
        in-place, putting a side-condition of non-shared-ness on the resultPtr
        argument to Tcl_FSMatchInDirectory, but everything would have broken
        before if that was shared *anyway*.

        * generic/tclEncoding.c (LoadTableEncoding): Removed reference to Tcl
        interpreter; it wasn't needed as direct object use is more efficient.

        * generic/tclPathObj.c: Made this file follow the style rules in the
        Engineering Manual more closely, and also take advantage of the
        internal object manipulation macros more.

        * generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Reorganized to have fewer
        magic flag variables and to separate the code that scans for a match
        from the code that processes a match body.

        It is a poor practice to directly set or append to the value of the
        objResult of an interp, because that value might be shared, and in
        that circumstance a Tcl_Panic() will be the result. Searched for
        example of this practice and replaced with safer alternatives, often
        using the Tcl_AppendResult() routine that dkf just rehabilitated.
        * library/dde/pkgIndex.tcl: Bump to dde 1.3.1

2004-10-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/SetResult.3: Made Tcl_AppendResult non-deprecated; better that
        people use it than most of the common alternatives!
        * generic/tclResult.c (Tcl_AppendResultVA): Make this work better with
        Tcl_Objs. [Patch 1041072]
        (Tcl_SetResult, Tcl_AppendElement): Change string to stringPtr to
        avoid C++ keywords.

2004-10-05  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclBasic.c (TclObjInvoke): More simplification of the
        TclObjInvoke routine toward unification with the rest of the
        evaluation stack.

        * generic/tclBasic.c (Tcl_CreateInterp, Tcl_DeleteInterp)
        (TclEvalObjvInternal, Tcl_LogCommandInfo):
        * generic/tclCmdAH.c (Tcl_CatchObjCmd):

        * generic/tclResult.c (Tcl_ResetResult, Tcl_SetObjErrorCode)
        (TclTransferResult):
        * generic/tclTrace.c (CallVarTraces):
        Reworked management of the "errorCode" data of an interp. That
        information is now primarily stored in a new private (Tcl_Obj *) field
        of the Interp struct, rather than using a global variable ::errorCode
        as the primary storage. The ERROR_CODE_SET flag bit value is no longer
        required to manage the value in its new location, and is removed.
        Variable traces are established to support compatibility for any code
        expecting the ::errorCode variable to hold the information.

        ***POTENTIAL INCOMPATIBILITY***
        Code that sets traces on the ::errorCode variable may notice a
        difference in timing of the firing of those traces.

        * generic/tclNamesp.c (Tcl_PopCallFrame): Removed Bug 1038021
        workaround. That bug is now fixed.

2004-10-04  Kevin B. Kenny  <kennykb@acm.org>

        * tests/clock.test (clock-34.*): Removed an antibug that forced
        comparison of [clock scan] results with the :localtime time zone. Now
        that [clock scan] uses the current time zone instead, the antibug
        caused several tests to fail. [Bug 1038554]

2004-10-04  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclParseExpr.c (GetLexeme): Ensure that the 'eq' and 'ne'
        operators are followed by non-alphabetic characters so lexemes can't
        run together. [Bug 884830]

        * doc/DictObj.3, doc/dict.n: Clarified that a dictionary is not
        order-preserving. [Bug 1032243] Also added another example to show off
        more ways of using a dictionary and a few other formatting
        improvements.

2004-10-02  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclDictObj.c (TraceDictPath, Tcl_DictObjPutKeyList): Add
        support for automatic creation of dictionary paths since that is what
        everyone seems to actually expect of the API! [Bug 1037235]
        (Tcl_DictObjNext): Make calling this after Tcl_DictObjDone non-fatal
        as that simplifies a number of internal APIs. This doesn't break any
        existing working code as it is a case which previously caused a panic.

2004-10-02  Don Porter  <dgp@users.sourceforge.net>

        * tests/namespace.test (namespace-8.7): Another test for save/restore
        of ::errorInfo and ::errorCode during global namespace teardown.

        * generic/tclProc.c (TclObjGetFrame, Tcl_UplevelObjCmd):

        references in the level object for speed.

2004-09-30  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclBasic.c (Tcl_CreateInterp):
        * generic/tclInt.h (Interp): Removed the flag bit value
        EXPR_INITIALIZED. It was set during interp creation and never tested.
        Whatever purpose it had is in the past.

        * generic/tclBasic.c (Tcl_EvalObjEx):   Removed the flag bit value
        * generic/tclInt.h (Interp):            USE_EVAL_DIRECT. It was used
        * generic/tcLTest.c (TestevalexObjCmd): only in the testing command
        * tests/parser.test (parse-9.2):        [testevalex] and nothing in
        the test suite made use of the capability it enabled.

        * generic/tclBasic.c (Tcl_AddObjErrorInfo): More re-organization
        * generic/tclCmdAH.c (Tcl_ErrorObjCmd):     of the management of
        * generic/tclCmdMZ.c (TclProcessReturn):    the errorCode value.
        * tests/error.test (error-6.4-9):

        * generic/tclNamespace.c (TclTeardownNamespace): Tcl_Obj-ified
        * tests/namespace.test (namespace-8.5,6):        the save/restore of
        ::errorInfo and ::errorCode during global namespace teardown. Revised
        the comment to clarify why this is done, and added tests that will
        fail if this is not done.

        * generic/tclResult.c (TclTransferResult): Added safety checks so that
        unexpected undefined ::errorInfo or ::errorCode will not lead to a
        segfault.

        * generic/tclTrace.c (TclCallVarTraces):  Save/restore the flag values
        * tests/var.test (var-16.1):              that define part of the
        interpreter state during variable traces. [Bug 1038021].

        uninitialised variable.

2004-09-27  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclBasic.c:   Removed internal routines TclInvoke,
        * generic/tclInt.decls: TclGlobalInvoke, TclObjInvokeGlobal and the
        * tests/basic.test:     portion of TclObjInvoke that handles calls
        without TCL_INVOKE_HIDDEN enabled. None of this code is called any
        longer within the core, and the superior public interface,
        Tcl_EvalObjv, is available for any external callers.

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

        * generic/tclEvent.c (HandleBgErrors): Updated [bgerror] invocations

        volume-relative pwd on Windows [Bug 1018980].

        935853]

        Continued refactoring of [clock] for TIP 173 changes. Broke the
        free-form parser apart so that the Bison parser is responsible for
        only parsing, while clock.tcl handles relative times like "next
        Thursday", "next January". This change is needed to make timezones
        other than :localtime and :Etc/UTC work with free-form scanning. This
        change closes out the issue identified as being "for another day" in
        my log message of 2004-09-08. The refactored code also eliminates the
        last known references to TclpStrftime and TclGetDate, so those
        routines (including compat/strftime.c) have been removed. The
        refactoring also has the benefit that all storage in the Bison parser
        is now on the C stack, eliminating any need for mutex protection
        around [clock scan]. Also, changed the Makefiles so that 'make
        gendate' is available on Windows as well as Unix.

        * generic/tclCmdAH.c (Tcl_FormatObjCmd): Removed some grubby
        * generic/tclObj.c (SetBooleanFromAny):  work-around code that was
        needed only because of Bug 868489.

        * generic/tclBasic.c (TclObjInvoke): Removed three unused variables to
        silence a compiler warning in VC++.

2004-09-27  Vince Darley  <vincentdarley@users.sourceforge.net>

        * unix/dltest/Makefile.in (clean): Fixup make clean rule so that it
        does not delete all files when SHLIB_SUFFIX is set to the empty string
        in a static build. [Bug 1016726]

2004-09-23  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclBasic.c:   Corrections to the 2004-09-21 commit
        * generic/tclExecute.c: regarding ERR_ALREADY_LOGGED. That commit
        * generic/tclNamesp.c:  caused Tk test send-10.7 to fail. Added
        * tests/namespace.test (25.7,8): tests in the Tcl test suite
        * tests/pkg.test (2.25,26):      to catch this error without the aid
        of Tk in the future.

        * generic/tclCmdAH.c (Tcl_ExprObjCmd):  Simplified the TclObjCmdProc
        of [expr] with a call to Tcl_ConcatObj.

2004-09-22  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclCmdMZ.c (TclProcessReturn):        Support the -errorline
        * generic/tclCompile.c (TclCompileScript):      option to [return].
        * tests/compile.test (16.23.*): Use that capability to defer reporting
        * tests/misc.test (1.2):        of parse errors until runtime. Updated
        tests to reflect change. [Bug 1032805]

2004-09-22  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c (INST_START_CMD):

        a loop exception was returned.

2004-09-22  Kevin B. Kenny  <kennykb@acm.org>

        * library/tzdata/America/Montevideo: Updated to reflect
        ftp://elsie.nci.nih.gov/pub/tzdata2004d.tar.gz. (Changes to
        Asia/Jerusalem were in the comments only.) [Routine maintenance - no

        * generic/tclCompCmds.c:        Tolerate [append] syntax errors
        * tests/appendComp.test (8.1):  at compile time, and allow runtime to
        raise the error (or succeed if a redefined [append] allows).

        * generic/tclBasic.c:   Reworked management of the interp flag
        * generic/tclCompile.c: ERR_ALREADY_LOGGED, to reduce its exposure.
        * generic/tclExecute.c: Still left several referebces that are just
        * generic/tclNamesp.c:  too nice on performace to do away with. These
        changes also resolve an inconsistency in the ::errorInfo values
        produced by [namespace eval x error foo bar] and [namespace eval x
        {error foo bar}].

        * generic/tclExecute.c (TclCompEvalObj):        Simplified the
        TclCompEvalObj routine. Much housekeeping now reliably happens

        * doc/interp.n: Tighten up wording on how [interp eval] and [interp
        invokehidden] operate w.r.t. stack frames. [Bug 926590]

2004-09-20  Don Porter  <dgp@users.sourceforge.net>

        * tests/error.test (error-6.2,3):       Added more tests to verify
        ::errorCode setting by/after a [catch].

2004-09-19  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCmdAH.c: removed outdated comment [Bug 1029518].

2004-09-18  David Gravereaux <davygrvy@pobox.com>

        * win/tclAppInit.c: Dde package can load into a safe interp. Claim
        this fact for the Tcl_StaticPackage() call when the shell is built
        with the TCL_USE_STATIC_PACKAGES option.

2004-09-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclExecute.c (TEBC-INST_LSHIFT,INST_RSHIFT): Ensure that
        large shifts end up shifting correctly. [Bug 868467]

        * doc/FileSystem.3, doc/OpenFileChnl.3: More documentation fixes from
        Mikhail Kolesnitchenko. [Patch 1022527]
        * doc/*: Standardize highlighting of symbols defined in tcl.h

2004-09-17  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclBasic.c (Tcl_AddObjErrorInfo, Tcl_LogCommandInfo):
        * generic/tclCmdAH.c ([catch], [error]):
        * generic/tclCmdMZ.c ([return]):
        * generic/tclProc.c (TclUpdateReturnInfo):
        * generic/tclResult.c (Tcl_SetErrorCodeVA, Tcl_SetObjErrorCode)
        (TclTransferResult):    Refactored so that all errorCode setting flows
        through Tcl_SetObjErrorCode(). This greatly reduces the number of
        different places in the code that need to know details about an
        internal bitflag field of the Interp struct. Also places errorCode
        setting in one place for easier future mods.

2004-09-17  Kevin B.Kenny  <kennykb@acm.org>

        * generic/tclDate.c:    Revised tclGetDate.y to use bison instead of
        * generic/tclGetDate.y: yacc to build the parser, eliminating all the
        * generic/tclInt.h:     complicated hackery involving 'sed'
        * unix/Makefile.in:     postprocessing. Rebuilt the parser.

2004-09-14  Kevin B. Kenny  <kennykb@acm.org>

        * generic/tclClock.c (ClockOldscanObjCmd): Silenced a compiler warning
        (long passed as a param where unsigend long was expected). 'Unsigned
        long' is wrong, but the fix is really to change the signature of
        TclGetDate to return a structure of its 'yy' variables and then do the
        remaining work inside clock.tcl. But, as I said on 2004-09-08, that's
        a job for another day. [Bug 1027993]

2004-09-10  Miguel Sofer <msofer@users.sf.net>

        * doc/interp.n:
        * generic/tclInterp.c (TclPreventAliasLoop, AliasCreate):
        * tests/interp.test (17.4-6, 19.3-4): fixing problems with renaming of
        aliases [Bugs 707104 1026493]. Fix designed by dgp.

2004-09-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclNamesp.c (NsEnsembleImplementationCmd): Add token field
        to internal rep of EnsembleCmdRep structure so that we can check it to
        see if the subcommand object is really being used with the same
        ensemble. [Bug 1026903]

2004-09-11  Kevin B. Kenny  <kennykb@acm.org>

        * generic/tclClock.c (TclMktimeObjCmd): Corrected a bad check for
        error return from 'mktime'.
        * generic/tclObj.c (Tcl_GetIntFromObj): Corrected a problem where
        demoting a wide to an int failed on a big-endian machine. [Bug
        1026125].
        * tests/clock.test (clock-43.1): Added regression test for error
        return from 'mktime'.

2004-09-11  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c (INST_CONCAT1): fix for [Bug 1025834]; avoid
        unnecessary string copies.

2004-09-10  David Gravereaux <davyrgvy@pobox.com>

        * tests/tcltest.test: tcltest-12.3-4 needed to have
        ::tcltest::loadScript set to empty in their -setup

2004-09-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclObj.c (SetIntOrWideFromAny): Rewritten integral value
        parsing code so that values do not flip so easily between numeric
        representations. Thanks to KBK for this! [Bug 868489]

        * generic/tclIO.c (Tcl_Seek): Make sure wide seeks do not fail to set
        ::errorCode on error. [Bug 1025359]

2004-09-10  Andreas Kupries  <andreask@activestate.com>

        * generic/tcl.h: Micro formatting fixes.
        * generic/tclIOGT.c: Channel version fixed, must be 3, to have
        wideseekProc. Thanks to David Graveraux <davygrvy@pobox.com>.

2004-09-11  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclNamespace.c (TclGetNamespaceForQualName): Resolved
        longstanding inconsistency in the treatment of the TCL_NAMESPACE_ONLY
        flag revealed by testing the 2004-09-09 commits against Itcl.
        TCL_NAMESPACE_ONLY now acts as specified in the pre-function comment,
        forcing resolution in the passed in context namespace. It has been
        incorrectly forcing resolution in the interp's current namespace.

2004-09-10  Kevin Kenny  <kennykb@acm.org>

        * library/clock.tcl: Fixed a bug where %z always put a plus sign on
        the time zone in :localtime.
        * tests/clock.test: Added test case for the above bug.

2004-09-10  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c (INST_CONCAT1): added a peephole optimisation
        for concatting an empty string. This enables replacing the idiom 'K $x
        [set x {}]' by '$x[set x {}]' for fastest execution.

2004-09-09  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinConsole.c: Calls to WriteFile and WriteConsoleA changed to
        WriteConsole for simplicity.

2004-09-09  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclNamesp.c (Tcl_ForgetImport):       Corrected faulty

        * tests/namespace.test: logic that relied exclusively on string
        matching and failed in the presence of [rename]s. [Bug 560297] Also
        corrected faulty prevention of [namespace import] cycles. [Bug 1017299]

2004-09-08  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclBasic.c (Tcl_CreateInterp):        Removed obsolete field
        for storing the string-based command procedure of built-in commands.
        We no longer have any string-based built-in commands!

2004-09-08  Kevin B. Kenny <kennykb@acm.org>

        * compat/strftime.c (_conv): Corrected a problem where hour 0 would
        format as a blank format group with %k.
        * doc/clock.n: Corrected a buglet in the header information. [Bug
        1024058]
        * generic/tclClock.c (TclClockMktimeObjCmd): Fixed a bug where the
        month was scanned incorrectly in -timezone :localtime.
        * tests/clock.test (clock-34.*,clock-40.1, clock-41.1): Adjusted the
        clock-34.* test cases so that the consistency check is performed in
        :localtime rather than the current time zone. This change allows
        dealing with issues where the C library has a different idea of DST
        conversion than Tcl. (Real fix would be to break TclGetDate into
        separate parser and time converter, and do the time conversion in
        clock.tcl. That's for another day.) Added regression test case for the
        bug where month was scanned incorrectly in -timezone :localtime. [Bug
        1023779] Added regression test case for %k at the zero hour.

2004-09-07  David Gravereaux <davygrvy@pobox.com>

        * win/makefile.vc: some quoting needed to be removed as it was
        breaking with VC7. [Bug 1023150]

2004-09-07  Kevin B. Kenny  <kennykb@acm.org>

        * doc/clock.n: Documented the default -format, and changed references
        to a (nonexistent) msgcat command to refer to the msgcat package. [Bug
        1023870]
        * generic/tclTimer.c: Removed a premature optimisation that attempted
        to store the assoc data in the client data; the optimisation caused a
        bug that [after] would overwrite its imports. [Bug 1016167]
        * library/clock.tcl (InitTZData, ClearCaches): Changed so that the
        in-memory time zone :UTC (and its aliases) always gets reinitialised,
        in case tzdata is absent. [Bug 1019537, 1023779]
        * library/tzdata/*: Regenerated.
        * tests/clock.test (clock-31.*, clock-39.1): Corrected a problem where
        the 'system' locale tests fail on a non-English Windows machine. [Bug
        1023761]. Added a test to make sure that alias time zones load
        correctly. [Bug 1023779].
        * tests/timer.test (timer-1.1, timer-2.1): Changed to (one hopes!) be
        more resilient on an overloaded system, if [after 200] sleeps for 300
        ms or longer.
        * tools/tclZIC.tcl (writeLinks): Corrected a problem where alias time
        zone names were written incorrectly, causing them to fail to load at
        run time. [Bug 1023779].
        * win/tclWinTime.c (Tcl_GetTime): Eliminated CPUID tests on Win64 -
        assuming that HAL vendors now do a better job of keeping the
        performance counters synchronized among CPU's. [Bug 1020445]

        updated one piece of code to ensure correct behaviour when an

2004-08-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        -unknown handler instead of relying on objv[0], which may contain
        useless info in the presence of [namespace import]. Problem found by

2004-08-21  Kevin B. Kenny  <kennykb@acm.org>

        * tests/clock.test (clock-38.1): Changed TZ setting to specify CET in
        excruciating detail to deal with systems that lack the Posix defaults
        for DST changes (and to be formally correct with the change dates for
        CET).

2004-08-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

2004-08-18  Andreas Kupries  <andreask@activestate.com>

        * library/init.tcl: Integrated TIP #189. We source a separate file

        should beeasier to maintain, and easier to backport/install in 8.4
        installations.

        Note: Usage of Tcl Modules is restricted to non-safe interps. It
        cannot be loaded into a safe interp.

        * library/tm.tcl: New file, the v2 reference implementation for TIP

                Implementation of TIPs #173 and #209.

        The [clock] command is now a Tcl ensemble, with most of its
        functionality written in Tcl and callouts to C code only to access
        low-level functions such as localtime, mktime and tzset.

        In addition to the functionality changes called out in the two TIPs,
        it is worth noting that the [clock] command in a safe slave
        interpreter is now an alias to the [clock] command in the master, and
        that [clock] is otherwise not expected to function entirely correctly
        in safe interps. C code that simply does Tcl_MakeSafe needs to be
        aware that [clock] may need special handling. (It appears unlikely
        that such code actually exists.)

        One incompatibility of note is that if the time zone cannot be
        determined from the TZ, TCL_TZ environment variables, or from the
        Windows control panel, so that the C library must be used for date and
        time conversions, then times outside the range of time_t will fail;
        they used to return bad data silently.

        Many thanks to all the many people who assisted with testing,
        debugging, criticism of the specification, and localisation. Deserving
        of particular mention are Joe English, Clif Flynt, Donal K. Fellows,
        Jeff Hobbs, Cameron Laird, Arjen Markus, Reinhard Max, Christopher
        Nelson, Steve Offutt, Donald G. Porter, Pascal Scheffers, Peter da
        Silva and Richard Suchenwirth-Bauersachs.

2004-08-03  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclNamesp.c (MakeCachedEnsembleCommand): Initialize the
        epoch field cached in the subcommand. [Bug 989298]
        (NsEnsembleImplementationCmd): Plug a leak (thanks to Miguel Sofer for
        spotting it with valgrind) and reduce the number of goto labels to
        make the code clearer.

2004-08-02  Don Porter  <dgp@users.sourceforge.net>

        * library/package.tcl (pkg_mkIndex):    Updated [pkg_mkIndex] to make
        use of [glob -directory $dir -tails] and return options.

        TIP#207 IMPLEMENTATION

        * doc/interp.n:         Added support for a -namespace option to the
        * generic/tclBasic.c:   [interp invokehidden] command.  Also added an
        * generic/tclInt.h:     internal routine TclObjInvokeNamespace() and
        * generic/tclInterp.c:  corrected the flag names TCL_FIND_ONLY_NS and
        * generic/tclNamesp.c:  TCL_CREATE_NS_IF_UNKNOWN that are passed to the
        * generic/tclTrace.c:   internal routine TclGetNamespaceForQualName().
        * tests/interp.test:    [Patch 981841]

        * generic/tclLiteral.c (TclCleanupLiteralTable):        Corrected
        * tests/compile.test (compile-12.4):    flawed deletion of literal
        internal reps that could lead to accessing of freed memory. Thanks to
        Kevin Kenny for test case and fix [Bug 1001997].

2004-07-30  Don Porter  <dgp@users.sourceforge.net>

        * tests/safe.test (safe-2.1):  Disabled senseless test.  [Bug 999612]

        * library/auto.tcl (auto_reset):  Removed "protected" list of commands
        from [auto_reset]. All entries in the auto_index can be re-loaded.
        * library/package.tcl: Updated comment to reflect 2004-07-28 commit.

        * generic/tclEvent.c (Tcl_Finalize):    Re-organized Tcl_Finalize so
        that Tcl_ExitProc's that call Tcl_Finalize recursively do not cause
        deadlock. [Patch 999084 fixes Tk Bug 714956]

2004-07-30  Daniel Steffen  <das@users.sourceforge.net>

        * unix/configure:
        * unix/tcl.m4 (SC_CONFIG_CFLAGS): Darwin: instead of setting PLAT_OBJS
        to explict object files in tcl.m4, refer to MAC_OSX_OBJS makefile var.
        * unix/Makefile.in: added MAC_OSX_OBJS variable.

2004-07-29  Don Porter  <dgp@users.sourceforge.net>

        * library/package.tcl: [::pkg::create] is now an alias. Test safe-2.1
        will now fail until Bug 999612 is corrected.

2004-07-28  Don Porter  <dgp@users.sourceforge.net>

        * library/package.tcl:          Moved private command
        * library/tclIndex:             [pkg_compareExtension] into ::tcl::Pkg.
        * tests/pkg_mkIndex.test:       Also moved implementation of
        [::pkg::create] to [::tcl::Pkg::Create].

2004-07-25  Pat Thoyts  <patthoyts@users.sourceforge.net>

        * tests/io.test: Make io-61.1 create file as binary to pass on Win32

2004-07-23  Miguel Sofer <msofer@users.sf.net>

        * generic/tclVar.c: simplify tclLocalVarNameType, removing the
        reference to the corresponding proc. The reference is now seen as
        unnecessary, and it may cause leaking circular references under some
        circumstances (see for example [Bug 994838]).

2004-07-22  Don Porter  <dgp@users.sourceforge.net>

        * tests/eofchar.data (removed): Test io-61.1 now generates its own
        * tests/io.test:        file of test data as needed.

2004-07-20  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclEvent.c:       Correct threaded obj allocator to
        * generic/tclInt.h:         fully cleanup on exit and allow for
        * generic/tclThreadAlloc.c: reinitialization. [Bug 736426]
        * unix/tclUnixThrd.c:       (mistachkin, kenny)
        * win/tclWinThrd.c:

2004-07-21  Kevin Kenny  <kennykb@acm.org>

        * generic/tclBasic.c (DeleteInterpProc):
        * generic/tclLiteral.c (TclCleanupLiteralTable):
        * generic/tclInt.h: added a TclCleanupLiteralTable function, called
        from DeleteInterpProc, that frees internal representations of shared
        literals early when an interpreter is being deleted. This change
        corrects a number of memory mismanagement issues in the cases where
        the internal representation of one literal contains a reference to
        another, and avoids conditions such as resolved variable names
        referring to procedure and namespace contexts that no longer exist.
        [Bug 994838]

2004-07-20  Daniel Steffen  <das@users.sourceforge.net>

        * unix/Makefile.in:
        * win/Makefile.in: added 'install-private-headers' makefile target to
        allow optionally installing private tcl headers. [FR 922727]

        * macosx/Makefile: use new 'install-private-headers' target to install
        private headers into framework. [FR 922727]

        * unix/tclUnixFile.c (NativeMatchType): added support for readonly
        matching of user immutable files (where available).

        * macosx/tclMacOSXBundle.c: dynamically acquire address for
        CFBundleOpenBundleResourceMap symbol, since it is only present in full
        CoreFoundation on Mac OS X and not in CFLite on pure Darwin.

2004-07-19  Zoran Vasiljevic <vasiljevic@users.sf.net>

        * win/tclwinThrd.c: redefined MASTER_LOCK to call TclpMasterLock.
        Fixes [Bug 987967]

2004-07-17  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclIOUtil.c: fix to rare 'cd' infinite loop in normalization
        with vfs [Bug 991420].
        * tests/fileSystem.test: added test for above bug.

        * doc/FileSystem.3: clarified documentation of posix error codes in
        'remove directory' FS proc - 'EEXIST' is used to signify a non-empty
        directory error (bug reported against tclvfs).

2004-07-16  Jeff Hobbs  <jeffh@ActiveState.com>

        * unix/Makefile.in, unix/tcl.m4:     move (C|LD)FLAGS after their
        * unix/configure.in, unix/configure: _DEFAULT to allow for env setting
        to override m4 switches. Move SC_MISSING_POSIX_HEADERS up and
        consolidate calls to limit redundancy in configure.
        (CFLAGS_WARNING): Remove -Wconversion
        (SC_ENABLE_THREADS): Set m4 to force threaded build when built against
        a threaded Tcl core.

2004-07-16  Andreas Kupries  <andreask@activestate.com>

        * generic/tclIOCmd.c (Tcl_FcopyObjCmd): Corrected a typo in the
        generation of error messages and simplified by reusing data in a
        variable instead of retrieving the string again. Fixes [Bug 835289].

        * doc/OpenFileChnl.3: Added description of the behaviour of
        Tcl_ReadChars when its 'charsToRead' argument is set to -1. Fixes [Bug
        934511].

        * doc/CrtCommand.3: Added note that the arguments given to the command
        proc of a Tcl_CreateCommand are in utf8 since Tcl 8.1. Closing [Patch
        414778].

        * doc/ChnlStack.3: Removed the declaration that the interp argument to
        Tcl_(un)StackChannel can be NULL. This fixes [Bug 881220], reported by
        Marco Maggi <marcomaggi@users.sourceforge.net>.

        * tests/socket.test: Accepted two new testcases by Stuart Casoff
        <stwo@users.sourceforge.net> checking that -server and -async don't go
        together [Bug 796534].

        * unix/tclUnixNotfy.c (NotifierThreadProc): Accepted Joe Mistachkin's
        patch for [Bug 990500], properly closing the notifier thread when its
        exits.

2004-07-15  Andreas Kupries  <andreask@activestate.com>

        * unix/tclUnixThrd.c (TclpFinalizeMutex): Accepted Joe Mistachkin's
        patch for [Bug 990453], closing leakage of mutexes. They were not
        destroyed properly upon finalization.

2004-07-15  Andreas Kupries  <andreask@activestate.com>

        * generic/tclIO.h (CHANNEL_INCLOSE):       New flag. Set in
        * generic/tclIO.c (Tcl_UnregisterChannel): 'Tcl_Close' while the
        * generic/tclIO.c (Tcl_Close):             close callbacks are
        run. Checked in 'Tcl_Close' and 'Tcl_Unregister' to prevent recursive
        call of 'close' in the close-callbacks. This is a possible error made
        by implementors of virtual filesystems based on 'tclvfs', thinking
        that they have to close the channel in the close handler for the
        filesystem.

2004-07-14  Andreas Kupries  <andreask@activestate.com>

        * generic/tclIO.c:
        * generic/tclIO.h:
        * Not reverting, but #ifdef'ing the changes from May 19, 2004 out of
        the core. This removes the ***POTENTIAL INCOMPATIBILITY*** for channel
        drivers it introduced. This has become possible due to Expect gaining
        a BlockModeProc and now handling blockingg and non-blocking modes
        correctly. Thus [SF Tcl Bug 943274] is still fixed if a recent enough
        version of Expect is used.

        * doc/CrtChannel.3: Added warning about usage of a channel without a
        BlockModeProc.

2004-07-15  Andreas Kupries  <andreask@pliers.activestate.com>

        * generic/tclIOCmd.c (Tcl_PutsObjCmd): Added length check to the old
        depreceated newline syntax, to ensure that only "nonewline" is
        accepted. [Tcl SF Bug 985869], reported by Joe Mistachkin
        <mistachkin@users.sourceforge.net>.

2004-07-15  Zoran Vasiljevic <vasiljevic@users.sf.net>

        * generic/tclEvent.c (Tcl_Finalize): stuffed memory leak incurred by
        re-initializing of TSD slots after the last call to
        TclFinalizeThreadData (done from within Tcl_FinalizeThread()). We
        basically just repeat the TclFinalizeThreadData() once more before
        tearing down TSD keys in TclFinalizeSynchronization(). There should be
        more elaborate mechanism in place for handling such issues, based on
        thread cleanup handlers registered on the OS level. Such change
        requires much more work and would also require TIP because some
        visible parts of Tcl API would have to be modified. In the meantime,
        this will do.

        * generic/tclNotify.c (TclFinalizeNotifier): Added conditional
        notifier finalization based on the fact that an TclInitNotifier has
        been called for the current thread. This fixes the [Bug 770053] again.
        Hopefully this time w/o unwanted side-effects.

2004-07-15  Kevin Kenny  <kennykb@acm.org>

        * generic/tclLiteral.c (TclReleaseLiteral): Removed unused variable
        'codePtr' to silence a message from VC++.

2004-07-15  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.c (TclCompileScript):
        * generic/tclLiteral.c (TclReleaseLiteral): fix for [Bug 467523],
        which resurfaced with the latest changes. The previous strategy was to
        have special code in TclReleaseLiteral to handle the self-references
        generated by empty scripts. The new approach avoids the self-reference
        altogether, by having empty scripts return an unshared literal.

2004-07-15  Zoran Vasiljevic <vasiljevic@users.sf.net>

        * generic/tclEvent.c (NewThreadProc): Backout of changes to fix the
        [Bug 770053]. See SF bugreport for more info.

2004-07-11  Miguel Sofer <msofer@users.sf.net>

        * generic/tclBasic.c (Tcl_EvalEx): leak fix by dgp, release
        objv[objectsUsed] on error.

2004-07-11  Miguel Sofer <msofer@users.sf.net>

        * generic/tclParse.c (Tcl_SubstObj): leak fix by dgp, release result
        on error.

2004-07-11  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclNamesp.c (BuildEnsembleConfig): Don't forget to clean out
        references when deleting the hash table.
        * generic/tclDictObj.c (Tcl_DictObjRemoveKeyList): Oops, forgot to
        delete value object when removing the hash entry. [Bug 989093 in part]

2004-07-11  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c (TEBC): fixed leak of expandNestList objs when
        there is an error while an expansion is in progress (code added at
        checkForCatch).

2004-07-11  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclIOUtil.c: fix to 'cd' bug when vfs is active [tclvfs Bug
        986944] - this bug recently introduced by some threading fixes. Need
        to work out how to add tests for this.

2004-07-10  Kevin Kenny  <kennykb@acm.org>

        * tests/clock.test (clock-2.11): Changed the test so that it isn't an
        infinite loop when run under valgrind on a slow virtual machine.
        Thanks to Miguel Sofer for the bug report. Also put in code to restore
        env(LC_TIME) after tests complete, silencing a warning from 'make
        TESTFLAGS="-debug 1" test'.

2004-07-08  Miguel Sofer <msofer@users.sf.net>

        * generic/tclBasic.c (DeleteInterpProc): reverted the modification of
        3 days ago, as the leak of [Bug 983660] is now handled by the change
        in TclCleanupByteCode.
        * generic/tclCompile.c (TclCleanupByteCode): let each bytecode remove
        its references to literals at interp deletion, without updating the
        dying literal table.
        * generic/tclLiteral.c (TclDeleteLiteralTable): with the above change
        to TclCleanupByteCode, this function now removes a single reference to
        the literal object and cleans up its own structures.

2004-07-08  Kevin Kenny  <kennykb@acm.org>

        * win/tclWinInit.c (AppendEnvironment): Silenced a compilation warning
        about a type mismatch.

2004-07-07  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.c (TclCompileScript): fix for [Bug 458361].
        Single-word scripts are compiled with an unshared cmdName to avoid
        shimmering between bytecode and cmdName reps.

2004-07-07  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclCmdMZ.c (TclMergeReturnOptions):  Simplified logic and
        removed potential memory leak. [Bug 986257].

2004-07-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * tools/man2help2.tcl (setTabs, IPmacro): Added support for the more
        advanced *roff macros used in Tk's doc/bind.n

        * generic/tclObj.c (TclInitObjSubsystem): Declare all current object
        types.

2004-07-06  Don Porter  <dgp@users.sourceforge.net>

        * tests/cmdMZ.test (cmdMZ-return-2.17): Added a test that a word
        containing backslash-quoted value is treated correctly.

        * generic/tclCompile.c (TclWordKnownAtCompileTime): [Bug 986196]
        Corrected flaw above and the flaw that caused TCL_TOKEN_SIMPLE_WORDs
        to have their original word value copied ( "{a b}" ) rather than the
        actual value ( "a b" ). Thanks to Kevin Kenny for report and tests.

2004-07-06  Kevin B. Kenny  <kennykb@acm.org>

        * tests/cmdMZ.test (cmdMZ-return-2.15,cmdMZ-return-2.16): Added a test
        that a return code containing spaces is correctly returned.

2004-07-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * tools/man2html2.tcl (IPmacro, setTabs): Added support for the more
        advanced *roff macros used in Tk's doc/bind.n

2004-07-05  Miguel Sofer <msofer@users.sf.net>

        * generic/tclBasic.c (DeleteInterpProc): fix for [Bug 983660], found
        by pspjuth. Tear down the global namespace before freeing the interp
        handle, to allow the bytecodes to free their non-shared literals.
        * generic/tclLiteral.c (TclReleaseLiteral): moved special code for
        self-ref so that it is also used for non-shared literals. Possible bug
        found by inspection.

2004-07-03  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c (ExprRoundFunc):
        * tests/expr-old.test (39.1): added support for wide integers to
        round(); [Bug 908375], reported by Hemang Lavana.

2004-07-03  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.h:
        * generic/tclInt.decls:
        * generic/tclIntDecls.h:
        * generic/tclStubInit.c: Moved declaration of TclCompEvalObj() from
        tclCompile.h to the internal stubs table, for compiler
        experimentation.

2004-07-02  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/regcomp.c (stid): correct minor pointer size error

        * generic/tclPipe.c (TclCreatePipeline): applied TIP #202 patch that
        * doc/exec.n, tests/exec.test:           adds 2>@1 as a special case
        redirection of stderr to the result output.

2004-07-02  Kevin B. Kenny  <kennykb@acm.org>

        * tests/io.test: Changed several tests to run the event loop rather
        than just calling [update] periodically, avoiding intermittent
        failures (usually in io-29.32) that stemmed from unreaped processes on
        Windows.
        * tests/winPipe.test (winpipe-1.11): Fixed a bug that caused test to
        fail if the path name of the working directory contained whitespace
        [Bug 678430]

2004-07-01  Vince Darley  <vincentdarley@users.sourceforge.net>

        * tests/fileSystem.test: Added test for [Bug 970529]

2004-07-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * win/README.binary, win/README: Updated references to Tcl and Tk 8.4
        to point to 8.5 instead. Thanks to Theo Verelst for spotting this.
        * generic/tcl.h: Added note to help prevent those changes from getting
        missed in the future.

        * doc/Namespace.3, doc/load.n, doc/Limit.3: Typo fixes and remove
        duplicate documentation. [Bug 983146]

2004-06-30  Don Porter  <dgp@users.sourceforge.net>

        * tests/fileSystem.test: Minor correction to new fileSystem-9.X tests
        so that they clean up temporary directories correctly.

2004-06-30  Vince Darley  <vincentdarley@users.sourceforge.net>

        * doc/filename.n: clarified behaviour concerning trailing slashes in
        filenames [Bug 971976]

        * win/tclWinFile.c:
        * tests/fileSystem.test: fix and tests for [Bug 979879]

2004-06-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        TIP#188 IMPLEMENTATION

        * doc/string.n, tests/string.test:       Add 'wideinteger' to things
        * generic/tclCmdMZ.c (Tcl_StringObjCmd): that can be tested for with
        the [string is] subcommand. [Patch 940915, by Kevin Kenny]

2004-06-29  Don Porter  <dgp@users.sourceforge.net>

        * win/tclWinInit.c:     Corrected reference counting flaw in recent
        changes. Thanks to Pat Thoyts. [Bug 981893].

2004-06-29  Vince Darley  <vincentdarley@users.sourceforge.net>

        * win/tclWin32Dll.c: fix to compilation with VC++ 5.2

2004-06-29  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * library/safe.tcl: Make sure that the temporary variable is local to
        the namespace and not inadvertently global. [Bug 981733]

2004-06-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * tests/unixNotfy.test: Modified constraints so that testing with a
        threaded tclsh (not tcltest) will not hang.

2004-06-23  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclThreadStorage.c: Corrected type casting errors that led
        to calculation of a negative index value, thus accesses outside the
        threadStorageCache array, thus memory corruption. Crash observed on
        Mac OS X platform.

2004-06-23  Joe Mistachkin  <joe@mistachkin.com>

        * generic/tclThread.c: Implements platform independent thread storage
        * generic/tclThreadStorage.c: mechanism and fixes associated bugs on
        platforms where there is limited thread local storage space
        (Win98/WinNT4). [Patch 976496]

        * generic/tclInt.decls:
        * generic/tclIntDecls.h: Added thread storage functions to the
        * generic/tclStubInit.c: internal stubs table.

        * unix/Makefile.in:
        * unix/configure:
        * unix/tcl.m4:
        * win/makefile.vc:
        * win/rules.vc:
        * win/Makefile.in: Modified the unix, VC++, and Cygwin build systems
        * win/configure: to include the new "tclThreadStorage.c" and the new
        * win/tcl.m4: USE_THREAD_STORAGE define.

2004-06-23  Pat Thoyts  <patthoyts@users.sourceforge.net>

        * tests/io.test: Added -force to 18.1 and 18.2. This was failing on
        WinXP.

        * tests/winFCmd.test: Added a cleanup to winFCmd-16.11 to avoid a
        failure in 16.12.

        * tests/eofchar.data: Added -kb option to ensure a binary checkout to
        win32 systems. This fixes a failure in io-61.1

        * win/makefile.vc: fix for [Bug 977369] about launching tclsh to
        generate a tclConfig.sh with the nmake build system

2004-06-23  Kevin B. Kenny  <kennykb@acm.org>

        * tests/winDde.test (createChildProcess): Added a 200-ms delay (with
        the event loop live) when shutting down the test DDE server process.
        With the delay in place, nuisance failures of tests winDde-4.2, -6.5,
        and -6.6 appear to be much less frequent. [Bug 957449]

2004-06-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * tests/*.test: Standardize use of platform constraints.

        * unix/tclUnixInit.c (GetStackSize, TclpCheckStackSpace):
        * unix/tclUnixThrd.c (TclpThreadGetStackSize): Added code to check
        whether the C stack is about to be exceeded, from [Patch 746378] by
        Joe Mistachkin but with substantial revisions.

2004-06-22  Kevin Kenny  <kennykb@acm.org>

        * generic/tclEvent.c (NewThreadProc): Fixed broken build on Windows
        caused by missing TCL_THREAD_CREATE_RETURN.

        * tests/stack.test (stack-3.1): Corrected nuisance error in threaded
        builds.

2004-06-22  Zoran Vasiljevic <vasiljevic@users.sf.net>

        * generic/tclEvent.c:
        * generic/tclInt.h:
        * unix/tclUnixNotfy.c:
        * unix/tclUnixThrd.c:
        * win/tclWinThrd.c: [Bug 770053]. See bug report for more information
        about what it does.

        * tests/unixNotfy.test: rewritten to use tcltest::threadReap to
        gracefully wait for the test thread to exit. Otherwise we got a race
        condition with main thread exiting before the test thread. This
        exposed the long-standing Tcl lib issue with resource
        garbage-collection on application exit.

2004-06-21  Mo DeJong  <mdejong@users.sourceforge.net>

        * win/tclWin32Dll.c (DllMain, _except_dllmain_detach_handler)
        (TclpCheckStackSpace, _except_checkstackspace_handler)
        (TclWinCPUID, _except_TclWinCPUID_detach_handler):
        * win/tclWinChan.c (Tcl_MakeFileChannel)
        (_except_makefilechannel_handler):
        * win/tclWinFCmd.c (DoRenameFile, _except_dorenamefile_handler)
        (DoCopyFile, _except_docopyfile_handler):
        Rework pushing of exception handler function pointer so that compiling
        with gcc -O3 works. Remove empty function call to avoid compiler
        warning. Mark the DllMain function as noinline to avoid compiler error
        from duplicated asm labels in generated code.

2004-06-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclThreadAlloc.c (Ptr2Block): Rewrote so as to maximize the
        chance of detecting and reporting a memory inconsistency without
        relying on things being consistent. [Bug 975895]

2004-06-18  Don Porter  <dgp@users.sourceforge.net>

        * tests/load.test:      Relaxed strictness of error message matching
        for test load-2.3 so that it will pass on Mac OSX.

        * generic/tclEncoding.c: Static TclFindEncodings -> FindEncodings.
        * generic/tclInt.h:     Updated TclpFindExecutable() so that failed
        * generic/tclUtil.c:    attempts to find the executable are saved
        * unix/tclUnixFile.c:   just as successful finds are. [Patch 966053]
        * unix/tclUnixTest.c:

2004-06-18  Kevin B. Kenny  <kennykb@acm.org>

        * tests/winFCmd.test (winFCmd-16.12): Changed test to compute the
        target directory, so as not to fail if the user's HOME isn't the root.

2004-06-19  Daniel Steffen  <das@users.sourceforge.net>

        * unix/tcl.m4: autoconf 2.5 fixes in Darwin section.
        * unix/configure: autoconf-2.57

2004-06-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * unix/tclUnixInit.c (localeTable): Added some more locale to encoding
        mapping info from Jim Huang <jserv@kaffe.org>

        * generic/tclInt.h (PendingObjData,TclFreeObjMacro,etc):
        * generic/tclObj.c (TclFreeObj): Added scheme for making TclFreeObj()
        avoid blowing up the C stack when freeing up very large object trees.
        [Bug 886231]

        * win/tclWinInit.c (SetDefaultLibraryDir): Fix logic, simplify and add
        comments.

2004-06-17  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclObj.c:     Added missing space in panic message.

        * win/tclWinInit.c:     Inform [tclInit] about the default library
        directory via the ::tclDefaultLibrary variable. This should correct a
        problem with my 2004-06-11 commit. Better solutions still in the
        works. Thanks to Joe Mistachkin for pointing out the breakage.

2004-06-16  Don Porter  <dgp@users.sourceforge.net>

        * doc/library.n:        Moved variables ::auto_oldpath and
        * library/auto.tcl:     ::unknown_pending into ::tcl namespace.
        * library/init.tcl:     [Bugs 808319, 948794]

2004-06-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/binary.n: Added some notes to the documentation of the 'a'
        format to address the point raised in [RFE 768852].

2004-06-15  Jeff Hobbs  <jeffh@ActiveState.com>

        * unix/tclConfig.sh.in (TCL_EXTRA_CFLAGS): set to @CFLAGS@, which is
        the configure-time CFLAGS. Addendum to m4 change on 2004-05-26.

2004-06-14  Kevin Kenny  <kennykb@acm.org>

        * win/Makefile.in: Corrected compilation flags for tclPkgConfig.c so
        that it doesn't require Stubs.
        * generic/tclBasic.c (Tcl_CreateInterp): Removed comment stating that
        TclInitEmbeddedConfigurationInformation needs Stubs; with the change
        above, the comment is now erroneous.

2004-06-11  Don Porter  <dgp@users.sourceforge.net>

        * doc/Encoding.3:       Removed bogus claims about tcl_libPath.

        * generic/tclInterp.c (Tcl_Init):       Stopped setting the
        tcl_libPath variable. [tclInit] can get all its directories without it.

        * tests/unixInit.test:  Modified test code that made use of
        tcl_libPath variable.

        * unix/tclUnixInit.c:   Stopped setting the tclDefaultLibrary variable,
        execept on the Mac OS X platform with HAVE_CFBUNDLE. In that
        configuration we should seek some way to make use of the TIP 59
        facilities and get rid of that usage of tclDefaultLibrary as well.

        * generic/tclInterp.c:  Updated [tclInit] to make $env(TCL_LIBRARY) an
        absolute path, and to include the scriptdir,runtime configuration value
        on the search path for init.tcl.

        * unix/tclUnixInit.c:   The routines Tcl_Init() and TclSourceRCFile()
        * win/tclWinInit.c:     had identical implementations for both win and
        * generic/tclInterp.c:  unix. Moved to a single generic implementation.
        * generic/tclMain.c:
        * library/init.tcl:
        * generic/tclInitScript.h (removed):
        * unix/Makefile.in:
        * win/tcl.dsp:

        * unix/configure.in:    Updated TCL_PACKAGE_PATH value to handle
        * win/configure.in:     --libdir configuration.

        * unix/configure.in:    autoconf-2.57
        * win/configure.in:

        * generic/tclBasic.c (Tcl_CreateInterp): Moved call to
        TclInitEmbeddedConfigurationInformation() earlier in
        Tcl_CreateInterp() so that other parts of interp creation and
        initialization may access and use the config values.

2004-06-11  Kevin Kenny  <kennykb@acm.org>

        * win/tclAppInit.c: Restored the 'setargv' procedure when compiling
        with mingw. Apparently, the command line parsing in mingw doesn't work
        as well as that in vc++, and the result was (1) that winPipe-8.19
        failed, and (2) that 'make test' would work at all only with
        TESTFLAGS='-singleproc 1'. [Bug 967195]

2004-06-10  Zoran Vasiljevic <vasiljevic@users.sf.net>

        * generic/tclIOUtil.c: removed forceful setting of the private cached
        current working directory rep from within the Tcl_FSChdir(). We
        delegate this task to the Tcl_FSGetCwd() which does this task anyway.
        The relevant code is still present but disabled temporarily until the
        change proves correct. The Tcl test suite passes all test with the
        given change so I suppose it is good enough.

2004-06-10  Don Porter  <dgp@users.sourceforge.net>

        * unix/tclUnixInit.c (TclpInitLibraryPath):     Disabled addition of
        * win/tclWinInit.c (TclpInitLibraryPath):       relative-to-executable
        directories to the library search path. A first step in reform of
        Tcl's startup process.

        ***POTENTIAL INCOMPATIBILITY***
        Attempts to directly run ./tclsh or ./tcltest out of a build directory
        will either fail, or will make use of an installed script library in
        preference to the one in the source tree. Use `make shell` or `make
        runtest` instead.

        * tests/unixInit.test:  Modified tests to suit above changes.

        * generic/tclPathObj.c: Corrected [file tail] results when operating
        on a path produced by TclNewFSPathObj(). [Bug 970529]

2004-06-09  Zoran Vasiljevic <vasiljevic@users.sf.net>

        * generic/tclIOUtil.c: partially corrected [Bug 932314]. Also
        corrected return values of Tcl_FSChdir() to reflect those of the
        underlying platform-specific call. Originally, return codes were mixed
        with those of Tcl.

2004-06-08  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.c:
        * generic/tclExecute.c: handle warning [Bug 969066]

2004-06-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclHash.c (RebuildTable): Move declaration of variable so it
        is only declared when it is used. [Bug 969068]

2004-06-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/lsearch.n: Added correct option to example. [Bug 968219]

2004-06-05  Kevin B. Kenny  <kennykb@acm.org>

        * generic/tcl.h: Corrected Tcl_WideInt declarations so that the mingw
        build works again.
        * generic/tclDecls.h:                   Changes to the tests for clock
        * generic/tclInt.decls:                 frequency in Tcl_WinTime so
        * generic/tclIntDecls.h:                that any clock frequency is
        * generic/tclIntPlatDecls.h:            accepted provided that all
        * generic/tclPlatDecls.h:               CPU's in the system share a
        * generic/tclStubInit.c:                common chip, and hence,
        * tests/platform.test (platform-1.3):   presumably, a common clock.
        * win/tclWin32Dll.c (TclWinCPUID):      This change necessitated a
        * win/tclWinTest.c (TestwincpuidCmd)    small burst of assembly code
        * win/tclWinTime.c (Tcl_GetTime):       to read CPU ID information,
        which was added as TclWinCPUID in the internal Stubs. To test this
        code in the common case of a single-processor machine, a
        'testwincpuid' command was added to tclWinTest.c, and a test case in
        platform.test. Thanks to Jeff Godfrey and Richard Suchenwirth for
        reporting this bug. [Bug 976722]

2004-06-04  Don Porter  <dgp@users.sourceforge.net>

        * generic/tcl.h:        Restored #include <stdio.h> to tcl.h,
        rejecting the "fix" for "Bug" 945570. Tcl_FSSeek() needs the values of
        SEEK_SET, etc. and too many extensions rely on tcl.h providing stdio.h
        for them.

2004-06-02  Jeff Hobbs  <jeffh@ActiveState.com>

        * win/tclWinFile.c (TclpFindExecutable): when using GetModuleFileNameA
        (Win9x), convert from CP_ACP to WCHAR then convert back to utf8.
        Adjunct to 2004-04-07 fix.

2004-06-02  David Gravereaux <davygrvy@pobox.com>

        * tests/winPipe.test (winpipe-6.1): blocking set to 1 before closing
        to ensure we get an exitcode. The windows pipe channel driver doesn't
        differentiate between a blocking and non-blocking close just yet, but
        will soon. Part of [Bug 947693]

2004-06-02  Vince Darley  <vincentdarley@users.sourceforge.net>

        * doc/file.n: fix to documentation of 'file volumes' (Bug 962435)

2004-06-01  David Gravereaux <davygrvy@pobox.com>

        * win/makefile.vc: check for either MSDEVDIR or MSVCDIR being in the
        environment, for VC7. [Bug 942214]

        * generic/tclIO.c (Tcl_SetChannelOption): -buffersize wasn't
        understanding hexidecimal notation nor was reporting number conversion
        errors. The behavior to silently ignore settings outside the
        acceptable range of Tcl_SetChannelBufferSize (<10 or >1M) is
        unchanged. This silent ignoring behavior might be up for review soon.

2004-05-30  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinPipe.c:
        * win/tclWinPort.h:  Reworked the win implementation of Tcl_WaitPid to
        support exitcodes in the 'signed short' range. Even though this range
        is non-portable, it is valid on windows. Detection of exception codes
        are now more accurate. Previously, an application that exited with
        ExitProcess((DWORD)-1); was improperly reported as exiting with
        SIGABRT.

2004-05-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclInterp.c: Added comments describing the purposes of each
        function in the limit implementation and rewrote the names of some
        non-public functions for greater clarity of purpose.
        * doc/interp.n: Added note about what happens when a limited
        interpreter creates a slave interpreter.
        * doc/Limit.3: Added manual page for the resource limit subsystem's C
        API. [Bug 953903]

2004-05-29  Joe English  <jenglish@users.sourceforge.net>

        * doc/global.n, doc/interp.n, doc/lrange.n: Fix minor markup errors.

2004-05-28  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/*.n: Added examples to many (too many to list) more man pages.

2004-05-25  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c:
        * generic/tclVar.c: using (ptrdiff_t) instead of (int) casting to
        correct compiler warnings [Bug 961657], reported by Bob Techentin.

2004-05-27  Kevin B. Kenny  <kennykb@acm.org>

        * tests/clock.test: Added a single test for the presence of %G in
        [clock format], and conditioned out the clock-10.x series if they're
        all going to fail because of a broken strftime() call. [Bug 961714]

2004-05-27  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclHash.c (CompareStringKeys): Added #ifdef to allow people
        to instruct this function to use strcmp(). [FRQ 951168]

        * generic/tclVar.c: Moved declarations into #if guards so they only
        happen when required.
        * unix/tclUnixPort.h: Guard declaration of strtod() so it is only
        enabled when we don't have a declaration in stdlib.h
        * unix/tclUnixThrd.c (Tcl_CreateThread):        Added declarations
        * unix/tclUnixTest.c (AlarmHandler):            and casts so that
        * unix/tclUnixChan.c (TtyModemStatusStr):       all functions are
        * generic/tclScan.c (Tcl_ScanObjCmd):           defined before use
        * generic/tclDictObj.c (InvalidateDictChain):   and no cross-type
        * generic/tclCmdMZ.c (Tcl_StringObjCmd):        uses are performed.

        The overall effect is to make building with gcc with the additional
        flags -Wstrict-prototypes -Wmissing-prototypes produce no increase in
        the total number of warnings (except for main(), which is undeclared
        for traditional reasons.)

2004-05-26  Jeff Hobbs  <jeffh@ActiveState.com>

        * unix/Makefile.in:  Rework configure ordering to TCL_LINK_LIBS,
        * unix/tcl.m4:       ENABLE_SHARED, CONFIG_CFLAGS, & ENABLE_SYMBOLS
        * unix/configure:    before TCL_EARLY_FLAGS and TCL_64BIT_FLAGS
        * unix/configure.in: (about 400 lines earlier) in configure.in. This
        forces CFLAGS configuration to be done before many tests, which is
        needed for 64-bit builds and may affect other builds. Also make
        CONFIG_CFLAGS append to CFLAGS directly instead of using EXTRA_CFLAGS,
        and have LDFLAGS append to any existing value. [Bug 874058]
        * unix/dltest/Makefile.in: change EXTRA_CFLAGS to DEFS

2004-05-26  Don Porter  <dgp@users.sourceforge.net>

        * library/tcltest/tcltest.tcl:  Correction to debug prints and testing
        * library/tcltest/pkgIndex.tcl: if TCLTEST_OPTIONS value. Corrected
        * tests/tcltest.test:           double increment of numTestFiles in
        -singleproc 1 configurations. Updated tcltest-19.1 to tcltest 2.1
        behavior. Corrected tcltest-25.3 to not falsely report a failure in
        tcltest.test. Bumped to tcltest 2.2.6. [Bugs 960560, 960926]

2004-05-25  Jeff Hobbs  <jeffh@ActiveState.com>

        * doc/http.n (http::config): add -urlencoding option (default utf-8)
        * library/http/http.tcl:     that specifies encoding conversion of
        * library/http/pkgIndex.tcl: args for http::formatQuery. Previously
        * tests/http.test:           undefined, RFC 2718 says it should be
        utf-8. 'http::config -urlencoding {}' returns previous behavior, which
        will throw errors processing non-latin-1 chars. Bumped http package to
        2.5.0.

2004-05-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclInterp.c (DeleteScriptLimitCallback): Move all deletion
        of script callback hash table entries to happen here so the entries
        are correctly removed at the right time. [Bug 960410]

2004-05-25  Miguel Sofer <msofer@users.sf.net>

        * docs/global.n: added details for qualified variable names [Bug
        959831]

2004-05-25  Miguel Sofer <msofer@users.sf.net>

        * generic/tclNamesp.c (Tcl_FindNamespaceVar):
        * tests/namespace.test (namespace-17.10-12): reverted commit of
        2004-05-23 and removed the tests, as it interferes with the varname
        resolver and there are apps that break (AlphaTk). A fix will have to
        wait for Tcl9.

        * generic/tclVar.c: Caching of namespace variables disabled: no simple
        way was found to avoid interfering with the resolver's idea of
        variable existence. A cached varName may keep a variable's name in the
        namespace's hash table, which is the resolver's criterion for
        existence.

        * tests/namespace.c (namespace-17.10): testing for interference
        between varname caching and name resolver.

2004-05-25  Kevin Kenny  <kennykb@acm.org>

        * tests/winFCmd.test: Correct test for the presence of a CD-ROM so
        that it doesn't misdetect some other sort of filesystem with a
        write-protected root as being a CD-ROM drive. [Bug 918267]

2004-05-25  Don Porter  <dgp@users.sourceforge.net>

        * tests/winPipe.test:   Protect against path being set
        * tests/unixInit.test:  Unset path when done.
        * tests/unload.test (unload-3.1): Verify [pkgb_sub] does not exist.
        Delete interps when done.
        * tests/stringComp.test:        stop re-use of string.test test names
        * tests/regexpComp.test:        stop re-use of regexp.test test names
        * tests/namespace.test (namespace-46.3): Verify [p] does not exist.
        * tests/http.test:      Clear away the custom [bgerror] when done.
        * tests/io.test:        Take care to use namespace variables.
        * tests/autoMkindex.test (autoMkindex-5.2): Use variable "result"
        that gets cleaned up.
        * tests/exec.test:      Clean up the "path" array.
        * tests/interp.test (interp-9.3): Initialize res, so prior values
        cannot make the test fail.
        * tests/execute.test (execute-8.1):  Updated to remove the trace set
        on ::errorInfo. When left in place, that trace can cause later tests
        to fail.

2004-05-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclBasic.c: Removed references to Tcl_RenameCommand from
        * generic/tcl.h:      comments. [Bug 848440, second part]

        * tests/fCmd.test: Rewrote tests that failed consistently on NFS so
        they either succeed (through slightly more liberal matching of the
        results) or are constrained to not run. [Bug 931312]

        * doc/bgerror.n: Use idiomatic open flags for working with log
        files. [Bug 959602]

2004-05-24  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclExecute.c (VerifyExprObjType): use GET_WIDE_OR_INT to
        properly have tclIntType used for smaller values. This corrects [TclX
        Bug 896727] and any other 3rd party extension that created math
        functions but was not yet WIDE_INT aware in them.

2004-05-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclInterp.c (TclInitLimitSupport): Made limits work on
        platforms where sizeof(void*)!=sizeof(int). [Bug 959193]

2004-05-24 Miguel Sofer <msofer@users.sf.net>

        * doc/set.n: accurate description of name resolution process,
        referring to namespace.n for details [Bug 959180]

2004-05-23  Miguel Sofer <msofer@users.sf.net>

        * generic/tclNamesp.c (Tcl_FindNamespaceVar): [Bug 959052] fixed,
        insuring that no "zombie" variables are found.
        * generic/tclVar.c (TclLookupSimpleVar): comments re [Bug 736729]
        (predecessor of [Bug 959052]) removed.
        * tests/namespace.test: added tests 17.10-12

        The patch modifies non-documented behaviour, and passes every test in
        the testsuite. However, scripts relying on the old behaviour may
        break.
        Note that the only behaviour change concerns the creative writing of
        unset variables. More precisely, which variable will be created when
        neither a namespace variable nor a global variable by that name
        exists, as defined by [info vars]. The new behaviour is that the
        namespace resolution process deems a variable to exist exactly when
        [info vars] finds it - ie, either it has value, or else it was "fixed"
        by a call to [variable].
        Note: this patch was removed on 2002-05-25.

2004-05-22  Miguel Sofer <msofer@users.sf.net>

        * generic/tclVar.c (TclObjLookupVar, TclObjUnsetVar2): fix for new (in
        tcl8.4) exteriorisations of [Bug 736729] due to the use of
        tclNsVarNameType obj types. Reenabling the use of this objType ("VAR
        ref absolute" benchmark down to 66 ms, from 230). Added comments in
        TclLookupSimpleVar explaining my current understanding of [Bug
        736729].

2004-05-22  Miguel Sofer <msofer@users.sf.net>

        * generic/tclVar.c: fix for [Bug 735335]. The use of tclNsVarNameType
        objs is still disabled, pending resolution of [Bug 736729].

2004-05-21  Miguel Sofer <msofer@users.sf.net>

        * tests/namespace.test (namespace-41.3): removed the {knownBug}
        constraint: [Bug 231259] is closed since nov 2001, and the fix of [Bug
        729692] (INST_START_CMD) makes the test succeed.

2004-05-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclExecute.c (TclExecuteByteCode): Move a few declarations a
        short distance so pre-C99 compilers can cope. Also fix so
        TCL_COMPILE_DEBUG path compiles...

2004-05-21  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c (TclExecuteByteCode): reorganised TEBC
        automatic variables, defining them in tight blocks instead of at the
        function level. This has three purposes:
        - it simplifies the analysis of individual instructions
        - it is preliminary work to the non-recursive engine
        - it allows a better register allocation by the optimiser; under
        gcc3.3, this results in up to 10% runtime in some tests

2004-05-20  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclInterp.c (TclLimitRemoveAllHandlers):
        * generic/tclBasic.c (DeleteInterpProc):
        * tests/interp.test (interp-34.7): Ensure that all limit callbacks are
        deleted when their interpreters are deleted. [Bug 956083]

2004-05-19  Kevin B. Kenny  <kennykb@acm.org>

        * win/tclWinFile.c (TclpMatchInDirectory): fix for an issue where
        there was a sneak path from Tcl_DStringFree to SetErrorCode(0). The
        result was that the error code could be reset between a call to
        FindFirstFileEx and the check of its status return, leading to a
        bizarre error return of {POSIX unknown {No error}}. (Found in
        unplanned test - no incident logged at SourceForge.)

2004-05-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * tests/interp.test (interp-34.3): Rewrite this test to see if a time
        limit can catch a tight bytecode loop, a maximally aggressive
        denial-of-service attack.
        * generic/tclInterp.c (Tcl_LimitCheck): Fix the sense of checks to see
        whether a time limit has been extended.

        * tests/*.test: Many minor fixes, including ensuring that every test
        is run (so constraints control whether the test is doing anything) and
        making sure that constraints are always set using the API instead of
        poking around inside tcltest's internal datastructures. Also got rid
        of all trailing whitespace lines from the test suite!

2004-05-19  Andreas Kupries  <andreask@activestate.com>

        * generic/tclIO.c: Fixed [SF Tcl Bug 943274]. This is the same problem
        * generic/tclIO.h: as [SF Tcl Bug 462317], see ChangeLog entry
        2001-09-26. The fix done at that time is incomplete. It is possible to
        get around it if the actual read operation is defered and not executed
        in the event handler itself. Instead of tracking if we are in an read
        caused by a synthesized fileevent we now track if the OS has delivered
        a true event = actual data and bypass the driver if a read finds that
        there is no actual data waiting. The flag is cleared by a short or
        full read.

        ***POTENTIAL INCOMPATIBILITY*** for channel drivers.

2004-05-17  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclPathObj.c: fix to (Bug 956063) in 'file dirname'.
        * tests/cmdAH.test: added test for this bug.

        * doc/FileSystem.3: better documentation of refCount requirements of
        some FS functions (Bug 956126)

2004-05-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclTest.c (TestgetintCmd): Made the tests in get.test check
        * tests/get.test:                    Tcl_GetInt() since the core now
                                             avoids that function.

2004-05-18  Kevin B. Kenny  <kennykb@acm.org>

        * compat/strftime.c (_fmt, ISO8601Week):
        * doc/clock.n:
        * tests/clock.test: Major rework to the handling of ISO8601 week
        numbers. Now passes all the %G and %V test cases on Windows, Linux and
        Solaris [Bugs 500285, 500389, and 852944]

2004-05-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/append.n, doc/upvar.n: Added example.

2004-05-18  David Gravereaux <davygrvy@pobox.com>

        * win/makefile.vc: now generates a tclConfig.sh from Pat Thoyts [Patch
        909911]

2004-05-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/lsearch.n: Improve clarity (based on [Patch 955361] by Peter
        Spjuth)

        * tools/man2help2.tcl (macro,SHmacro): Added support for subsection
        (.SS) header macros.

        * doc/interp.n: Added user documentation for the TIP#143 resource
        limits and some examples.

        * generic/tclInterp.c (Tcl_LimitCheck, Tcl_LimitTypeReset): Reset the
        limit-exceeded flag when removing a limit.

2004-05-18  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c (TclExecuteByteCode): added comments to
        classify the variables according to their use in TEBC.

2004-05-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/global.n, doc/uplevel.n: Added an example.

        * tests/info.test (info-3.1): Corrected test result back to what it
        used to be in Tcl 7.* now that command counts are being correctly kept

        * generic/tclExecute.c (TEBC:INST_START_CMD): Make sure that the
        command-count is always advanced. Allows TIP#143 limits to tell that
        work is being done.

        * doc/list.n: Updated example to fit with the unified format.
        * doc/seek.n: Added some examples.

2004-05-17  Vince Darley  <vincentdarley@users.sourceforge.net>

        * win/tclWinFile.c:
        * tests/cmdAH.test: fix to (Bug 954263) where 'file executable' was
        case-sensitive.

2004-05-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/OpenFileChnl.3: Documented type of 'offset' argument to Tcl_Seek
        was wrong. [Bug 953374]

2004-05-16  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c (TclExecuteByteCode): remove one level of
        indirection for compiledLocals addressing.

2004-05-16  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c (INST_CALL_FUNC1): bugfix; restored
        (DE)CACHE_STACK_INFO pair around the call - the user defined math
        function could cause a recursive call to TEBC.

2004-05-16  Miguel Sofer <msofer@users.sf.net>

        * generic/tclBasic.c (Tcl_DeleteInterp):
        * generic/tclExecute.c (INST_START_CMD): interp deletion now modifies
        the compileEpoch, eliminating the need for the check for interp
        deletion in INST_START_CMD.

2004-05-16  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.h:
        * generic/tclCompile.c:
        * generic/tclExecute.c: changed implementation of {expand}, last
        chance while in alpha as ...

        ***POTENTIAL INCOMPATIBILITY***
        Scripts precompiled with ProComp under previous tcl8.5a versions may
        malfunction due to changed instruction numbers for
        INST_LIST_INDEX_IMM, INST_LIST_RANGE_IMM and INST_START_CMD.

2004-05-14  Kevin B. Kenny  <kennykb@acm.org>

        * generic/tclInt.decls:      Promoted TclpLocaltime and TclpGmtime
        * generic/tclIntDecls.h:     from Unix-specific stubs to the generic
        * generic/tclIntPlatDecls.h: internal Stubs table. Reran 'genstubs'
        * generic/tclStubInit.c:
        * unix/tclUnixPort.h:

        * generic/tclClock.c: Changed a buggy 'GMT' timezone specification
                              to the correct 'GMT0'. [Bug 922848]

        * unix/tclUnixThrd.c: Moved TclpGmtime and TclpLocaltime to
                              unix/tclUnixTime.c where they belong.

        * unix/tclUnixTime.c (TclpGmtime, TclpLocaltime, TclpGetTimeZone,
                              ThreadSafeGMTime [removed],
                              ThreadSafeLocalTime [removed],
                              SetTZIfNecessary, CleanupMemory):
        Restructured to make sure that the same mutex protects all calls to
        localtime, gmtime, and tzset. Added a check in front of those calls to
        make sure that the TZ env var hasn't changed since the last call to
        tzset, and repeat tzset if necessary. [Bug 942078] Removed a buggy
        test of the Daylight Saving Time information in 'gettimeofday' in
        favor of applying 'localtime' to a known value. [Bug 922848]

        * tests/clock.test (clock-3.14): Added test to make sure that changes
        to $env(TZ) take effect immediately.

        * win/tclWinTime.c (TclpLocaltime, TclpGmtime): Added porting layer
        for 'localtime' and 'gmtime' calls.

2004-05-14  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c:
        * generic/tclCompile.h: the math functions receive a pointer to top of
        the stack (tosPtr) instead of the execution environment (eePtr). First
        step towards a change in the execution stack management - it is now
        only used within TEBC.

2004-05-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        TIP#143 IMPLEMENTATION

        * generic/tclExecute.c (TclCompEvalObj, TclExecuteByteCode):
        * generic/tclBasic.c (TclEvalObjvInternal): Enable limit checking.
        * generic/tclInterp.c (Tcl_Limit*): Public limit API.
        * generic/tcl.decls:
        * tests/interp.test: Basic tests of command limits.

        * doc/binary.n:         TIP#129 IMPLEMENTATION [Patch 858211]
        * generic/tclBinary.c:  Note that the test suite probably has many more
        * tests/binary.test:    failures now due to alterations in constraints.

2004-05-12  Miguel Sofer <msofer@users.sf.net>

        Optimisations for INST_START_CMD [Bug 926164].
        * generic/tclCompile.c (TclCompileScript): avoid emitting
        INST_START_CMD as the first instruction in a bytecoded Tcl_Obj. It is
        not needed, as the checks are done before calling TEBC.
        * generic/tclExecute.c (TclExecuteByteCode): runtime peephole
        optimisation: check at INST_POP if the next instruction is
        INST_START_CMD, in which case we fall through.

2004-05-11  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/split.n, doc/join.n: Updated examples and added more.

2004-05-11  Vince Darley  <vincentdarley@users.sourceforge.net>

        * doc/glob.n: documented behaviour of symbolic links with 'glob -types
        d' (Bug 951489)

2004-05-11  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/scan.n: Updated the examples to be clearer about their relevance
        to the scan command.

2004-05-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/scan.n: Added examples.

2004-05-10  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinPipe.c (BuildCommandLine): Moved non-obvious appending
        logic to outside the loop and added commentary for its purpose. Also
        use the existence of contents in the linePtr rather than the scratch
        DString post the append, as this more clear.

        (TclpCreateProcess): When under NT, with no console, and executing a
        DOS application, the path priming does not need an ending space as
        BuildCommandLine() will do this for us.

2004-05-08  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclFileName.c:
        * generic/tclIOUtil.c: remove some compiler warnings on MacOS X.

2004-05-07  Chengye Mao <chengye.geo@yahoo.com>

        * win/tclWinPipe.c: refixed bug 789040 re-entered in rev 1.41. Let's
        be careful and don't re-enter previously fixed bugs.

2004-05-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/format.n: Added examples.

2004-05-07  Miguel Sofer <msofer@users.sf.net>

        * doc/unset.n: added upvar.n to the "see also" list

2004-05-07  Reinhard Max  <max@suse.de>

        * generic/tclEncoding.c:
        * tests/encoding.test: added support and tests for translating
        embedded null characters between real nullbytes and the internal
        representation on input/output [Bug 949905].

2004-05-07  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclFileName.c:
        * generic/tclIOUtil.c:
        * generic/tclFileSystem.h:
        * tests/fileSystem.test: fix for [Bug 943995], in which vfs-registered
        root volumes were not handled correctly as glob patterns in all
        circumstances.

2004-05-06  Miguel Sofer <msofer@users.sf.net>

        * generic/tclInt.h:
        * generic/tclObj.c (TclFreeObj): made TclFreeObj use the new macro
        TclFreeObjMacro(), so that the allocation and freeing of Tcl_Obj is
        defined in a single spot (the macros in tclInt.h), with the exception
        of the TCL_MEM_DEBUG case.
        The #ifdef logic for the corresponding macros has been reformulated to
        make it clearer.

2004-05-05  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/break.n, doc/continue.n, doc/for.n, doc/while.n: More examples.

2004-05-05  Don Porter  <dgp@users.sourceforge.net>

        * tests/unixInit.test (unixInit-2.10):  Test correction for Mac OSX.
        Be sure to consistently compare normalized path names. Thanks to
        Steven Abner (tauvan). [Bug 948177]

2004-05-05  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/CrtObjCmd.3: Remove reference to Tcl_RenameCommand; there is no
        such API. [Bug 848440]

2004-05-05  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinSock.c (SocketEventProc) : connect errors should fire both
        the readable and writable handlers because this is how it works on
        UNIX [Bug 794839]

        * generic/tclEncoding.c (TclFinalizeEncodingSubsystem):
        FreeEncoding(systemEncoding); moved to before the hash table iteration
        as it was causing a double free attempt under some conditions.

        * win/coffbase.txt: Added the tls extension to the list of preferred
        load addresses.

2004-05-04  Jeff Hobbs  <jeffh@ActiveState.com>

        * tests/fileSystem.test (filesystem-1.39): replace 'file volumes'
        * tests/fileName.test (filename-12.9,10):  lindex with direct C:/
        hard-coded because A:/ was being used and that is empty for most.

        * tests/winFCmd.test (winFCmd-16.12): test volumerelative $HOME

2004-05-04  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclAlloc.c:           Make sure Tclp*Alloc* routines get
        * generic/tclInt.h:             declared in the TCL_MEM_DEBUG and
        * generic/tclThreadAlloc.c:     TCL_THREADS configuration. [Bug 947564]

        * tests/tcltest.test:   Test corrections for Mac OSX. Thanks to Steven
        Abner (tauvan). [Bug 947440]

2004-05-04  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclEvent.c (TclSetLibraryPath): Suppress a warning.

2004-05-03  Andreas Kupries  <andreask@activestate.com>

        * Applied [Patch 868853], fixing a mem leak in TtySetOptionProc.
        Report and Patch provided by Stuart Cassoff <stwo@users.sf.net>.

2004-05-03  Miguel Sofer <msofer@users.sf.net>

        * generic/tclProc.c (TclCreateProc): comments corrected.

2004-05-03  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.c (TclCompileScript): setting the compilation
        namespace outside of the loop.

2004-05-03  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.c:
        * generic/tclInt.h: reverted fix for [Bug 926445] of 2004-04-02,
        restoring TCL_ALIGN to the header file. Todd Helfter reported that the
        macro is required by tbcload.

2004-05-03  Kevin Kenny  <kennykb@acm.org>

        * win/tclWin32Dll.c (TclpCheckStackSpace):
        * tests/stack.test (stack-3.1): Fix for undetected stack overflow in
        TclReExec on Windows. [Bug 947070]

2004-05-03  Don Porter  <dgp@users.sourceforge.net>

        * library/init.tcl:     Corrected unique prefix matching of
        interactive command completion in [unknown]. [Bug 946952]

2004-05-02  Miguel Sofer <msofer@users.sf.net>

        * generic/tclProc.c (TclObjInvokeProc):
        * tests/proc.test (proc-3.6): fix for bad quoting of multi-word proc
        names in error messages [Bug 942757]

2004-04-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/glob.n, doc/incr.n, doc/set.n:    More examples.
        * doc/if.n, doc/rename.n, doc/time.n:

2004-04-30  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclInt.h:             Replaced Kevin Kenny's temporary
        * generic/tclThreadAlloc.c:     fix for Bug 945447 with a cleaner,
        more permanent replacement.

2004-04-30  Kevin B. Kenny   <kennykb@acm.org>

        * generic/tclThreadAlloc.c: Added a temporary (or so I hope!)
        inclusion of "tclWinInt.h" to avoid problems when compiling on
        Win32-VC++ with --enable-threads. [Bug 945447]

2004-04-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/puts.n: Added a few examples.

2004-04-29  Don Porter  <dgp@users.sourceforge.net>

        * tests/execute.test (execute-8.2):     Avoid crashes when there is
        limited system stack space (threads-enabled).

        * doc/global.n:
        * doc/upvar.n:
        * generic/tclVar.c (ObjMakeUpvar):
        * tests/upvar.test (upvar-8.11):
        * tests/var.test (var-3.11): Avoid creation of unusable variables:
        [Bug 600812] [TIP 184].

2004-04-28  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/lsearch.n: Fixed fault in documentation of -index option [943448]

2004-04-26  Don Porter  <dgp@users.sourceforge.net>

        * unix/tclUnixFCmd.c (TclpObjNormalizePath):  Corrected improper
        positioning of returned checkpoint. [Bug 941108]

2004-04-26  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/open.n, doc/close.n: Updated (thanks to David Welton) to be
        clearer about pipeline errors and added example to open(n) that shows
        simple pipeline use. [Patches 941377,941380]

        * doc/DictObj.3: Added warning about the use of Tcl_DictObjDone and an
        example of use of iteration. [Bug 940843]

        * doc/Thread.3: Reworked to remove references to testing interfaces
        and instead promote the use of the Thread package. [Patch 932527]
        Also reworked and reordered the page for better readability.

2004-04-25  Don Porter  <dgp@users.sourceforge.net>

        * generic/tcl.h:        Removed obsolete declarations and #include's.
        * generic/tclInt.h:     [Bugs 926459, 926486]

2004-04-24  David Gravereaux <davygrvy@pobox.com>

        * win/tclWin32Dll.c (DllMain): Added DisableThreadLibraryCalls() for
        the DLL_PROCESS_ATTACH case. We're not interested in knowing about
        DLL_THREAD_ATTACH, so disable the notices.

2004-04-24  Daniel Steffen  <das@users.sourceforge.net>

        * generic/tclPort.h:
        * macosx/Makefile:
        * unix/Makefile.in: followup on tcl header reform [FR 922727]: removed
        use of relative #include paths in tclPort.h to allow installation of
        private headers outside of tcl source tree; added 'unix' dir to
        compiler header search path; add newly required tcl private headers to
        Tcl.framework on Mac OSX.

2004-04-23  Andreas Kupries  <andreask@activestate.com>

        * generic/tclIO.c (Tcl_SetChannelOption): Fixed [SF Tcl Bug 930851].
        When changing the eofchar we have to zap the related flags to prevent
        them from prematurely aborting the next read.

2004-04-25  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclPathObj.c: fix to [Bug 940281]. Tcl_FSJoinPath will now
        always return a valid Tcl_Obj when the input is valid.
        * generic/tclIOUtil.c: fix to [Bug 931823] for a more consistent
        Tcl_FSPathSeparator() implementation which allows filesystems not to
        implement their Tcl_FSFilesystemSeparatorProc if they wish to use the
        default '/'. Also fixed associated memory leak seen with, e.g., tclvfs
        package.
        * doc/FileSystem.3: documented Tcl_FSJoinPath return values more
        clearly, and Tcl_FSFilesystemSeparatorProc requirements.

2004-04-23  David Gravereaux <davygrvy@pobox.com>

        * win/tclWin32Dll.c: Removed my mistake from 4/19 of adding an exit
        handler to TclWinInit. TclWinEncodingsCleanup called from
        TclFinalizeFilesystem does the Tcl_FreeEncoding for us.

        * win/tclWinChan.c (Tcl_MakeFileChannel): Case for CloseHandle
        returning zero and not throwing a
        RaiseException(EXCEPTION_INVALID_HANDLE) now being done.

2004-04-22  David Gravereaux <davygrvy@pobox.com>

        * generic/tclEvent.c: TclSetLibraryPath's use of caching the stringrep
        of the pathPtr object to TclGetLibraryPath called from another thread
        was ineffective if the original's stringrep had been invalidated as
        what happens when it gets muted to a list.

        * win/tclWinTime.c: If the Tcl_ExitProc (StopCalibration) is called
        from the stack frame of DllMain's PROCESS_DETACH, the wait operation
        should timeout and continue.

        * generic/tclInt.h:
        * generic/tclThread.c:
        * generic/tclEvent.c:
        * unix/tclUnixThrd.c:
        * win/tclWinThrd.c: Provisions made so masterLock, initLock, allocLock
        and joinLock mutexes can be recovered during Tcl_Finalize.

2004-04-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/switch.n: Reworked the examples to be more systematically named
        and to cover some TIP#75 capabilities.

        * doc/cd.n: Documentation clarification from David Welton.

        * doc/exec.n: Added some examples, Windows ones from Arjen Markus and
        Unix ones by myself.

2004-04-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/Hash.3: Added note to Tcl_{First,Next}HashEntry docs that
        deleting the element they return is supported (and is in fact the only
        safe update you can do to the structure of a hashtable while an
        iteration is going over it.)

        * doc/bgerror.n: Added example from David Welton. [Patch 939473]

        * doc/after.n: Added examples from David Welton. [Patch 938820]

2004-04-19  David Gravereaux <davygrvy@pobox.com>

        * win/tclWin32Dll.c: Added an exit handler in TclWinInit() so
        tclWinTCharEncoding could be freed during Tcl_Finalize().

        * generic/tclEncoding.c: Added FreeEncoding(systemEncoding) in
        TclFinalizeEncodingSubsystem because its ref count was incremented in
        TclInitEncodingSubsystem.

2004-04-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/read.n: Added example from David Welton. [Patch 938056]

2004-04-19  Kevin B. Kenny   <kennykb@acm.org>

        * generic/tclObj.c (Tcl_GetDoubleFromObj) Corrected "short circuit"
        conversion of int to double. Reported by Jeff Hobbs on the Tcl'ers
        Chat.

2004-04-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/lreplace.n, doc/lrange.n, doc/llength.n:  More examples for
        * doc/linsert.n, doc/lappend.n:                 the documentation.

2004-04-16  Vince Darley  <vincentdarley@users.sourceforge.net>

        * doc/FileSystem.3: Corrected documentation of Tcl_FSUtime, and the
        corresponding filesystem driver Tcl_FSUtimeProc. [Bug 935838]

2004-04-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/socket.n: Added example from [Patch 936245].
        * doc/gets.n: Added example based on [Patch 935911].

2004-04-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclClock.c (Tcl_ClockObjCmd): Minor fault in a [clock
        clicks] error message.

2004-04-07  Jeff Hobbs  <jeffh@ActiveState.com>

        * win/tclWinInit.c (TclpSetInitialEncodings): note that WIN32_CE is
        also a unicode platform.
        * generic/tclEncoding.c (TclFindEncodings, Tcl_FindExecutable):
        * generic/tclInt.h:                         Correct handling of UTF
        * unix/tclUnixInit.c (TclpInitLibraryPath): data that is actually
        * win/tclWinFile.c (TclpFindExecutable):    "clean", allowing the
        * win/tclWinInit.c (TclpInitLibraryPath):   loading of Tcl from paths
        that contain multi-byte chars on Windows [Bug 920667]

        * win/configure:    define TCL_LIB_FLAG, TCL_BUILD_LIB_SPEC,
        * win/configure.in: TCL_LIB_SPEC, TCL_PACKAGE_PATH in tclConfig.sh.

2004-04-06  Don Porter  <dgp@users.sourceforge.net>

        Patch 922727 committed.  Implements three changes:

        * generic/tclInt.h:     Reworked the Tcl header files into a clean
        * unix/tclUnixPort.h:   hierarchy where tcl.h < tclPort.h < tclInt.h
        * win/tclWinInt.h:      and every C source file should #include
        * win/tclWinPort.h:     at most one of those files to satisfy its
        declaration needs. tclWinInt.h and tclWinPort.h also better organized
        so that tclWinPort.h includes the Windows implementation of
        cross-platform declarations, while tclWinInt.h makes declarations that
        are available on Windows only.

        * generic/tclBinary.c (TCL_NO_MATH):    Deleted the generic/tclMath.h
        * generic/tclMath.h (removed):          header file. The internal Tcl
        * macosx/Makefile (PRIVATE_HEADERS):    header, tclInt.h, has a
        * win/tcl.dsp:                          #include <math.h> directly,
        and file external to Tcl needing libm should do the same.

        * win/Makefile.in (WIN_OBJS):   Deleted the win/tclWinMtherr.c file.
        * win/makefile.bc (TCLOBJS):    It's a vestige from matherr() days
        * win/makefile.vc (TCLOBJS):    gone by.
        * win/tcl.dsp:
        * win/tclWinMtherr.c (removed):

        End Patch 922727.

        * tests/unixInit.test (unixInit-3.1):   Default encoding on Darwin
        systems is utf-8. Thanks to Steven Abner (tauvan). [Bug 928808]

2004-04-06  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * tests/cmdAH.test (cmdAH-18.2): Added constraint because
        access(...,X_OK) is defined to be permitted to be meaningless when
        running as root, and OSX exhibits this. [Bug 929892]

2004-04-02  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.c:
        * generic/tclInt.h: removed the macro TCL_ALIGN() from tclInt.h,
        replaced by the static macro ALIGN() in tclCompile.c [Bug 926445]

2004-04-02  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.h: removed redundant #ifdef _TCLINT [Bug 928415],
        reported by tauvan.

2004-04-02  Don Porter  <dgp@users.sourceforge.net>

        * tests/tcltest.test: Corrected constraint typos: "nonRoot" ->
        "notRoot". Thanks to Steven Abner (tauvan). [Bug 928353]

2004-04-01  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclInt.h:  Removed obsolete tclBlockTime* declarations. [Bug
        926454]

2004-04-01  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclIOUtil.c: Fix to privately reported vfs bug with 'glob
        -type d -dir . *' across a vfs boundary. No tests for this are
        currently possible without effectively moving tclvfs into Tcl's test
        suite.

2004-03-31  Don Porter  <dgp@users.sourceforge.net>

        * doc/msgcat.n: Clarified message catalog file encodings. [Bug 811457]
        * library/msgcat/msgcat.tcl: Updated internals to make use of [dict]s
        to store message catalog data and to use [source -encoding utf-8] to
        access catalog files. Thanks to Michael Sclenker. [Patch 875055, RFE
        811459] Corrected [mcset] to be able to successfully set a translation
        to the empty string. [mcset $loc $src {}] was incorrectly set the $loc
        translation of $src back to $src. Also changed [ConvertLocale] to
        minimally require a non-empty "language" part in the locale value. If
        not, an error raised prompts [Init] to keep looking for a valid locale
        value, or ultimately fall back on the "C" locale. [Bug 811461].
        * library/msgcat/pkgIndex.tcl:  Bump to msgcat 1.4.1.

2004-03-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclHash.c (HashStringKey): Cleaned up. This function is not
        faster, but it is a little bit clearer.
        * generic/tclLiteral.c (HashString): Applied logic from HashObjKey.
        * generic/tclObj.c (HashObjKey): Rewrote to fix fault which hashed
        every single-character object to the same hash bucket. The new code is
        shorter, simpler, clearer, and (happily) faster.

2004-03-30  Miguel Sofer <msofer@users.sf.net>

        * generic/tclExecute.c (TEBC): reverting to the previous method for
        async tests in TEBC, as the new method turned out to be too costly.
        Async tests now run every 64 instructions.

2004-03-30  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.c:     New instruction code INST_START_CMD that
        * generic/tclCompile.h:     allows checking the bytecode's validity
        * generic/tclExecute.c:     [Bug 729692] and the interp's readyness
        * tests/interp.test (18.9): [Bug 495830] before running the command.
        * tests/proc.test (7.1):    It also changes the mechanics of the async
        * tests/rename.test (6.1):  tests in TEBC, doing it now at command
        start instead of every 16 instructions.

2004-03-30  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclFileName.c:  Fix to Windows glob where the pattern is a
        * generic/tclIOUtil.c:    volume relative path or a network share [Bug
        * tests/fileName.test:    898238]. On windows 'glob' will now return
        * tests/fileSystem.test:  the results of 'glob /foo/bar' and 'glob
        \\foo\\bar' as 'C:/foo/bar', i.e. a correct absolute path (rather than
        a volume relative path).

        Note that the test suite does not test commands like
        'glob //Machine/Shared/*' (on a network share).

2004-03-30  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclPathObj.c:   Fix to filename bugs recently
        * tests/fileName.test:    introduced [Bug 918320].

2004-03-29  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclMain.c (Tcl_Main, StdinProc):      Append newline only
        * tests/basic.test (basic-46.1):                to incomplete scripts
        as part of multi-line script construction. Do not add an extra
        trailing newline to the complete script. [Bug 833150]

2004-03-28  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompile.c (TclCompileScript): corrected possible segfault
        when a compilation returns TCL_OUTLINE_COMPILE after having grown the
        compile environment [Bug 925121].

2004-03-27  Miguel Sofer <msofer@users.sf.net>

        * doc/array.n: added documentation for trace-realted behaviour of
        'array get' [Bug 449893]

2004-03-26  Don Porter  <dgp@users.sourceforge.net>

        * README:               Bumped version number to 8.5a2 to distinguish

        * generic/tclPathObj.c:   Fix to Windows-only volume relative path
        * tests/fileSystem.test:  normalization. [Bug 923568]. Also fixed
        another volume relative bug found while testing.

2004-03-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclNamesp.c (NsEnsembleImplementationCmd): Fix messed up
        handling of strncmp result which just happened to work in some libc
        implementations. [Bug 922752]

2004-03-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/StringObj.3: Inverted the sense of the documentation of how the
        bytes parameter is documented to match behaviour. [Bug 921464]

        fix recommended by Don Porter.

2004-03-18  Reinhard Max  <max@suse.de>

        * generic/tclIntDecls.h: Removed TclpTime_t. It wasn't really needed,
        * generic/tclInt.h:      but caused warnings related to
        * generic/tclInt.decls:  strict aliasing with GCC 3.3.
        * generic/tclClock.c:
        * generic/tclDate.c:

2004-03-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/lsearch.n: Improved examples on the advanced capabilities of
        lsearch (with the right options, set element removal can be done)
        following discussion on tkchat.

2004-03-16  Don Porter  <dgp@users.sourceforge.net>

        * doc/catch.n:  Compiled [catch] no longer fails to catch syntax
        errors. Removed the claims in the documentation that it does.
        * doc/return.n: Updated example to use [dict merge].

2004-03-16  Jeff Hobbs  <jeffh@ActiveState.com>

        * unix/configure, unix/tcl.m4: add -Wno-strict-aliasing for GCC to
        suppress useless type puning warnings.

2004-03-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * doc/file.n: *roff formatting fix. [Bug 917171]

2004-03-15  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinNotify.c: Fixed a mistake where the return value of
        MsgWaitForMultipleObjectsEx for "a message is in the queue" wasn't
        accurate. I removed the check on the case result==(WAIT_OBJECT_0 + 1)
        This was having the error of falling into GetMessage and waiting there
        by accident, which wasn't alertable through Tcl_AlertNotifier. I'll do
        some more study on this and try to find-out why.

2004-03-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        IMPLEMENTATION OF TIP#163
        * generic/tclDictObj.c (DictMergeCmd):  This is based on work by Joe
        * tests/dict.test (dict-20.*):          English in Tcl [FRQ 745851]
        * doc/dict.n:                           but not exactly.

2004-03-10  Kevin B. Kenny <kennykb@acm.org>

        * generic/tclGetDate.y (TclGetDate): Fix so that [clock scan
        <timeOfDay> -gmt true] uses the GMT base date instead of the local
        one. [Bug 913513]
        * tests/clock.test: Added test cases for wrong ISO8601 week number
        [Bug 500285] and wrong GMT base date [Bug 913513]. Several tests still
        fail on Windows, and these are actual faults in [clock scan]. Fix is
        still pending.
        * generic/tclDate.c: Regenerated.

2004-03-08  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclFileName.c:  Fix to 'glob -path' near the root
        * tests/fileName.test:    of the filesystem. [Bug 910525]

2004-03-08  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclParse.c (TclParseInit):    Modified TclParseInit so
        * generic/tclTest.c ([testexprparser]): that Tcl_Parse initialization
        conforms to documented promised about what fields will not be
        modified by what Tcl_Parse* routines. [Bug 910595]

2004-03-05  Mo DeJong  <mdejong@users.sourceforge.net>

        * win/configure: Regen.
        * win/configure.in: Check for define of MWMO_ALERTABLE in winuser.h.
        * win/tclWinPort.h: If MWMO_ALERTABLE is not defined in winuser.h then
        define it. This is needed for Mingw.

2004-03-05  Kevin B. Kenny <kennykb@acm.org>

        * generic/tclTest.c: Modified TesteventObjCmd to use a
        Tcl_QueuePosition in place of an 'int' for the enumerated queue
        position, to avoid a compiler warning on SGI. [Bug 771960]

2004-03-05  Kevin B. Kenny <kennykb@acm.org>

        * tests/registry.test: Applied fix from [Patch 910174] to make the test
        for an English-language system include any country code, rather than
        just English-United States.1252. Thanks to Pat Thoyts for the changes.

2004-03-04  Pat Thoyts  <patthoyts@users.sourceforge.net>

        * tests/registry.test: Applied fixed from [Bug 766159] to skip two
        tests on Win98 that depend on a Unicode registry (NT specific).

2004-03-04  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclInt.h (TclParseInit):      Factored the common code
        * generic/tclParse.c (TclParseInit):    for initializing a Tcl_Parse
        * generic/tclParseExpr.c:               struct into one routine.

2004-03-04  Pat Thoyts  <patthoyts@users.sourceforge.net>

        * library/reg/pkgIndex.tcl:  Added TIP #100 support to the
        * win/tclWinReg.c:           registry package [patch 903831]
        This provides a Windows test of the TIP #100 mechanism and a sample to
        show how unloading an extension can be done.

2004-03-04  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * unix/dltest/pkgua.c: Fix minor syntax problems. [Bug 909288]

2004-03-03  Jeff Hobbs  <jeffh@ActiveState.com>

        *** 8.5a1 TAGGED FOR RELEASE ***

        * changes: updated for 8.5a1

2004-03-03  David Gravereaux <davygrvy@pobox.com>

        * win/makefile.vc: default environment variable for VC++ is %MSDevDir%
        not %MSVCDir%, although vcvars32.bat sets both.

        * win/tclWinNotify.c (Tcl_WaitForEvent) : Allows an idling notifier to
        service "Asynchronous Procedure Calls" from its wait state. Only
        useful for extension authors who decide they might want to try
        "completion routines" with WriteFileEx(), as an example. From
        experience, I recommend that "completion ports" should be used instead
        as the execution of the callbacks are more managable.

2004-03-01  Jeff Hobbs  <jeffh@ActiveState.com>

        * README:           update patchlevel to 8.5a1
        * generic/tcl.h:
        * tools/tcl.wse.in, tools/tclSplash.bmp:
        * unix/configure, unix/configure.in, unix/tcl.spec:
        * win/README.binary, win/configure, win/configure.in:

        * unix/tcl.m4: update HP-11 build libs setup

2004-03-01  Don Porter  <dgp@users.sourceforge.net>

        * unix/tcl.m4 (SC_CONFIG_CFLAGS):       Allow 64-bit enabling on
        IRIX64-6.5* systems. [Bug 218561]
        * unix/configure:       autoconf-2.57

        * generic/tclTrace.c (TclCheckInterpTraces):    The TIP 62
        * generic/tclTest.c (TestcmdtraceCmd):  implementation introduced a
        * tests/trace.test (trace-29.10):       bug by testing the CallFrame
        level instead of the iPtr->numLevels level when deciding what traces
        created by Tcl_Create(Obj)Trace to call. Added test to expose the
        error, and made fix. [FRQ 462580]

2004-02-28  Vince Darley  <vincentdarley@users.sourceforge.net>

        * tests/fileSystem.test: fix to Tcl Bug 905163.
        * tests/fileName.test: fix to Tcl Bug 904705.

        * doc/{various}.n: removed 'the the' typos.

2004-02-26  Daniel Steffen  <das@users.sourceforge.net>

        * macosx/Makefile: fixed copyright year in Tcl.framework Info.plist

2004-02-25  Don Porter  <dgp@users.sourceforge.net>

        * tests/basic.test:     Made several tests more robust to the
        * tests/cmdMZ.test:     list-quoting of path names that might contain
        * tests/exec.test:      Tcl-special chars like { or [. Should help us
        * tests/io.test:        sort out [Bug 554068]
        * tests/pid.test:
        * tests/socket.test:
        * tests/source.test:
        * tests/unixInit.test:

2004-02-25  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclLoad.c (Tcl_LoadObjCmd): Missing dereference caused
        segfault with non-loadable extension. [Bug 904307]

        * unix/tclUnixChan.c (TcpGetOptionProc): Stop memory leak with very
        long hostnames. [Bug 888777]

2004-02-25  Pat Thoyts  <patthoyts@users.sourceforge.net>

        * win/tclWinDde.c: Removed some gcc warnings - except for the
        -Wconversion warning for GetGlobalAtomName. gcc is just wrong about
        this.

2004-02-24  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        IMPLEMENTATION OF TIP#100 FROM GEORGIOS PETASIS
        * generic/tclLoad.c (Tcl_UnloadObjCmd): Implementation.
        * tests/unload.test:                    Test suite.
        * unix/dltest/pkgua.c:                  Helper for test suite.
        * doc/unload.n:                         Documentation.
        Also assorted changes (mostly small) to several other files.

2004-02-23  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/regc_locale.c (cclass): Buffer was having its size reset
        instead of being released => memleak. [Bug 902562]

2004-02-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclLoad.c (Tcl_LoadObjCmd): Fixed memory leak due to an
        improper error exit route.

2004-02-20  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinSock.c (SocketThreadExitHandler): Don't call
        TerminateThread when WaitForSingleObject returns a timeout.
        Tcl_Finalize called from DllMain will pause all threads. Trust that
        the thread will get the close notice at a later time if it does ever
        wake up before being cleaned up by the system anyway.

2004-02-17  Don Porter  <dgp@users.sourceforge.net>

        * doc/tcltest.n:
        * library/tcltest/tcltest.tcl:  Changed -verbose default value to
        {body error} so that detailed information on unexpected errors in
        tests is provided by default, even after the fix for [Bug 725253]

2004-02-17  Jeff Hobbs  <jeffh@ActiveState.com>

        * tests/unixInit.test (unixInit-7.1):
        * unix/tclUnixInit.c (TclpInitPlatform): ensure the std fds exist to
        prevent crash condition [Bug 772288]

2004-02-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclCompCmds.c (TclCompileSwitchCmd): Bozo mistake in memory
        releasing order when in an error case. [Bug 898910]

2004-02-16  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclTrace.c (TclTraceExecutionObjCmd)
        (TclTraceCommandObjCmd): fix possible mem leak in trace info.

2004-02-12  Mo DeJong  <mdejong@users.sourceforge.net>

        * win/tclWinInit.c (AppendEnvironment): Use the tail component of the
        passed in lib path instead of just blindly using lib+4. That worked
        when lib was "lib/..." but fails for other values. Thanks go to
        Patrick Samson for pointing this out.

2004-02-10  David Gravereaux  <davygrvy@pobox.com>

        * win/nmakehlp.c: better macro grepping logic.

2004-02-07  David Gravereaux  <davygrvy@pobox.com>

        * win/makefile.vc:
        * win/rules.vc:
        * win/tcl.rc:
        * win/tclsh.rc: Added an 'unchecked' option to the OPTS macro so a
        core built with symbols can be linked to the non-debug enabled C
        run-time. As per discussion with Kevin Kenny. Called like this:

                nmake -af makefile.vc OPTS=unchecked,symbols

        This clarifies the meaning of the 'g' naming suffix to mean only that
        the binary requires the debug enabled C run-time. Whether the binary
        contains symbols or not is a different condition.

2004-02-06  Don Porter  <dgp@users.sourceforge.net>

        * doc/clock.n:  Removed reference to non-existent [file ctime].

2004-02-05  David Gravereaux  <davygrvy@pobox.com>

        * docs/tclvars.n: Added clarification of the tcl_platform(debug) var
        that it only refers to the flavor of the C run-time, and not whether
        the core contains symbols.

2004-02-05  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclFileName.c (SkipToChar): Corrected CONST and type-casting
        issues that caused compiler warnings.

2004-02-04  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclCmdAH.c (StoreStatData): Removed improper refcount
        decrement of the varName parameter. This error was causing segfaults
        following test cmdAH-28.7.

        * library/tcltest/tcltest.tcl: Corrected references to non-existent
        $name variable in [cleanupTests]. [Bug 833637]

2004-02-03  Don Porter  <dgp@users.sourceforge.net>

        * library/tcltest/tcltest.tcl:  Corrected parsing of single command
        line argument (option with missing value) [Bug 833910]
        * library/tcltest/pkgIndex.tcl: Bump to version 2.2.5.

2004-02-02  David Gravereaux <davygrvy@pobox.com>

        * generic/tclIO.c (Tcl_Ungets): Fixes improper filling of the channel
        buffer. This is the buffer before the splice. [Bug 405995]

2004-02-01  David Gravereaux <davygrvy@pobox.com>

        * tests/winPipe.test: more pass-thru commandline verifications.
        * win/tclWinPipe.c (BuildCommandLine): Special case quoting for '{'
        not required by the c-runtimes's parse_cmdline().
        * win/tclAppInit.c: Removed our custom setargv() in favor of the work
        provided by the c-runtime. [Bug 672938]

        * win/nmakehlp.c: defensive techniques to avoid static buffer
        overflows and a couple envars upsetting invokations of cl.exe and
        link.exe. [Bug 885537]

        * tests/winPipe.test: Added proof that BuildCommandLine() is not doing
        the "N backslashes followed a quote -> insert N * 2 + 1 backslashes
        then a quote" rule needed for the crt's parse_cmdline().
        * win/tclWinPipe.c: Fixed BuildCommandLine() to pass the new cases.

2004-01-30  David Gravereaux <davygrvy@pobox.com>

        * win/makefile.vc: Use the -GZ compiler switch when building for
        symbols. This is supposed to emulate the release build better to avoid
        hiding problems that only show themselves in a release build.

2004-01-29  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclPathObj.c: fix to [Bug 883143] in file normalization

2004-01-29  Vince Darley  <vincentdarley@users.sourceforge.net>

        * doc/file.n:
        * generic/tclFCmd.c
        * generic/tclTest.c
        * library/init.tcl
        * mac/tclMacFile.c
        * tests/fileSystem.test: fix to [Bug 886352] where 'file copy -force'
        had inconsistent behaviour wrt target files with insufficient
        permissions, particular from vfs->native fs. Behaviour of '-force' is
        now always consistent (and now consistent with behaviour of 'file
        delete -force'). Added new tests and documentation and cleaned up the
        'simplefs' test filesystem.

        * generic/tclIOUtil.c
        * unix/tclUnixFCmd.c
        * unix/tclUnixFile.c
        * win/tclWinFile.c: made native filesystems more robust to C code
        which asks for mount lists.

        * generic/tclPathObj.c: fix to [Bug 886607] removing warning/error
        with some compilers.

2004-01-28  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclObj.c (SetBooleanFromAny): Rewrite to do more efficient
        string->bool conversion.
        Many other minor whitespace/style fixes to this file too.

2004-01-27  David Gravereaux <davygrvy@pobox.com>

        * win/nmakehlp.c: Use '.\nul' as the sourcefile name instead of 'nul'
        so VC 5.2 doesn't try searching the path for it and failing with a
        possible dialogbox popping up about having to add a CD to an empty
        drive. Also added a SetErrorMode() call to disable any dialogs that
        cl.exe or link.exe might create. [Bug 885537]

2004-01-22  Vince Darley  <vincentdarley@users.sourceforge.net>

        * doc/file.n: clarified documentation of 'file system' [Bug 883825]
        * tests/fCmd.test: improved test result in failure case.

2004-01-22  Vince Darley  <vincentdarley@users.sourceforge.net>

        * tests/fileSystem.test: 3 new tests
        * generic/tclPathObj.c: fix to [Bug 879555] in file normalization.
        * doc/filename.n: small clarification to Windows behaviour with
        filenames like '.....', 'a.....', '.....a'.

        * generic/tclIOUtil.c: slight improvement to native cwd caching on
        Windows.

2004-01-21  David Gravereaux <davygrvy@pobox.com>

        * doc/Panic.3:  Mentions of 'panic' and 'panicVA' removed from the
        documentation.

2004-01-21  Vince Darley  <vincentdarley@users.sourceforge.net>

        * doc/FileSystem.3:
        * generic/tcl.decls:
        * generic/tclCmdAH.c
        * generic/tclDecls.h
        * generic/tclFCmd.c
        * generic/tclFileName.c
        * generic/tclFileSystem.h
        * generic/tclIOUtil.c

        * generic/tclInt.h
        * generic/tclIntDecls.h
        * generic/tclPathObj.c
        * generic/tclStubInit.c
        * generic/tclTest.c

        * win/tclWinFCmd.c
        * win/tclWinFile.c
        * win/tclWinInt.h

        Three main issues accomplished: (1) cleaned up variable names in the
        filesystem code so that 'pathPtr' is used throughout. (2) applied a
        round of filesystem optimisation with better handling and caching of
        relative and absolute paths, requiring fewer conversions. (3)
        clarifications to the documentation, particularly regarding the
        acceptable refCounts of objects. Some new tests added. Tcl benchmarks
        show a significant improvement over 8.4.5, and on Windows typically a
        small improvement over 8.3.5 (Unix still appears to require
        optimisation). TCL_FILESYSTEM_VERSION_2 introduced, but for internal
        use only. There should be no public incompatibilities from these
        changes. Thanks to dgp for extensive testing.

2004-01-19  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinPipe.c (Tcl_WaitPid): Fixed a thread-safety problem with
        the process list. The delayed cut operation after the wait was going
        stale by being outside the list lock. It now cuts within the lock and
        does a locked splice for when it needs to instead. [Bug 859820]

2004-01-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclCompile.c, generic/tclCompile.h: Two new opcodes,
        INST_LIST_INDEX_IMM and INST_LIST_RANGE_IMM, that have operand(s) of
        new type OPERAND_IDX4 which represents indexes into things like lists
        (and perhaps other things eventually.)
        * generic/tclExecute.c (TclExecuteByteCode): Implementation of the new
        opcodes. INST_LIST_INDEX_IMM does a simple [lindex] with either front-
        or end-based simple indexing. INST_LIST_RANGE_IMM does an [lrange]
        with front- or end-based simple indexing for both the reference to the
        first and last items in the range.
        * generic/tclCompCmds.c (TclCompileLassignCmd): Generate bytecode for
        the [lassign] command.

2004-01-17  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinInit.c: added #pragma comment(lib, "advapi32.lib") when
        compiling under VC++ so we don't need to specify it when linking.

2004-01-17  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclCmdIL.c (Tcl_LassignObjCmd): Add more shimmering
        protection for when the list is also one of the variables.

        BASIC IMPLEMENTATION OF TIP#57
        * generic/tclCmdIL.c (Tcl_LassignObjCmd): Implementation of the
        [lassign] command that takes full advantage of Tcl's object API.
        * doc/lassign.n: New file documenting the command.
        * tests/cmdIL.test (cmdIL-6.*): Test suite for the command.

2004-01-15  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinReg.c: Placed the requirement for advapi.lib into the
        object file itself with #pragma comment (lib, ...) when built with
        VC++. This will simplify linking for users of the static library.

        * win/rules.vc: Added new 'fullwarn' to the CHECKS commandline macro;
        sets $(FULLWARNINGS).

        * win/makefile.vc: Removed 'advapi.lib' from $(baselibs). Added new
        logic to crank-up the warning levels for both compile and link when
        $(FULLWARNINGS) is set. Some clean-up with how the resource files are
        built and how -DTCL_USE_STATIC_PACKAGES is sent when compiling the
        shells.

        * win/tclAppInit.c: Small change in how TCL_USE_STATIC_PACKAGES is
        used.

        * win/tcl.rc:
        * win/tclsh.rc: Some clean-up with how the resource files are built.
        Fixed 'OriginalFilename' problem that still thought a debug suffix was
        still 'd', now is 'g'.

2004-01-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclDictObj.c (TraceDictPath, DictExistsCmd): Adjusted
        behaviour of [dict exists] so a failure to look up a dictionary along
        the path of dicts doesn't trigger an error. This is how it was
        documented to behave previously... [Bug 871387]

        * generic/tclDictObj.c: Assorted dict fixes from Peter Spjuth relating
        to [Bug 876170].
        (SetDictFromAny): Make sure that lists retain their ordering even when
        converted to dictionaries and back.
        (TraceDictPath): Correct object reference count handling!
        (DictReplaceCmd, DictRemoveCmd): Stop object leak.
        (DictIncrCmd,DictLappendCmd,DictAppendCmd,DictSetCmd,DictUnsetCmd):
        Simpler handling of reference counts when assigning to variables.
        * tests/dict.test (dict-19.2): Memory leak stress test

2004-01-13  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclCmdMZ.c (Tcl_SwitchObjCmd):  Silence compiler warnings.

        Patch 876451: restores performance of [return]. Also allows forms such
        as [return -code error $msg] to be bytecompiled.

        * generic/tclInt.h:     Factored Tcl_ReturnObjCmd() into two pieces:
        * generic/tclCmdMZ.c:   TclMergeReturnOptions(), which can parse the
        options to [return], check their validity, and create the
        corresponding return options dictionary, and TclProcessReturn(), which
        takes that return options dictionary and performs the [return]
        operation.

        * generic/tclCompCmds.c: Rewrote TclCompileReturnCmd() to call
        TclMergeReturnOptions() at compile time so the return options
        dictionary is computed at compile time (when it is fully known). The
        dictionary is pushed on the stack along with the result, and the code
        and level values are included in the bytecode as operands. Also
        supports optimized compilation of un-[catch]ed [return]s from procs
        with default options into the INST_DONE instruction.

        * generic/tclExecute.c: Rewrote INST_RETURN instruction to retrieve
        the code and level operands, pop the return options from the stack,
        and call TclProcessReturn() to perform the [return] operation.

        * generic/tclCompile.h: New utilities include TclEmitInt4 macro
        * generic/tclCompile.c: and TclWordKnownAtCompileTime().

        End Patch 876451.

        * generic/tclFileName.c (Tcl_GlobObjCmd): Latest changes to management
        of the interp result by Tcl_GetIndexFromObj() exposed improper interp
        result management in the [glob] command procedure. Corrected by
        adopting the Tcl_SetObjResult(Tcl_NewStringObj) pattern. This stopped
        a segfault in test filename-11.36. [Bug 877677]

2004-01-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

        * generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct, Tcl_WrongNumArgs):
        Create fresh objects instead of using the one currently in the
        interpreter, which isn't guaranteed to be fresh and unshared. The cost
        for the core will be minimal because of the object cache, and this
        fixes [Bug 875395].

2004-01-12  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompExpr.c (CompileLandOrLorExpr): cosmetic changes.

2004-01-12  Miguel Sofer <msofer@users.sf.net>

        * generic/tclCompExpr.c (CompileLandOrLorExpr): new logic, fewer
        instructions. As a side effect, the instructions INST_LOR and
        INST_LAND are now never used.
        * generic/tclExecute.c (INST_JUMP*): small optimisation; fix a bug in
        debug code.

2004-01-11  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinThrd.c (Tcl_ConditionNotify): condPtr must be dereferenced
        to see if there are waiters else uninitialized datum is manipulated.
        [Bug 849007 789338 745068]

2004-01-09  David Gravereaux <davygrvy@pobox.com>

        * generic/tcl.h: Renamed and deprecated #defines moved to within the
        #ifndef TCL_NO_DEPRECATED block. This allows us to build Tcl to check
        for deprecated functions in use, such as panic() and Tcl_Ckalloc(). By
        request from DKF. Extensions that build with -DTCL_NO_DEPRECATED now
        have these macros as restricted.
        ***POTENTIAL INCOMPATIBILITY***

        * win/makefile.vc:
        * win/rules.vc:  Added -DTCL_NO_DEPRECATED usage to makefile.vc.
        Called like this:   nmake -af makefile.vc CHECKS=nodep

2004-01-09  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclIOUtil.c: fix to infinite loop in TclFinalizeFilesystem
        [Bug 873311]
