2001-12-28  Jeff Hobbs  <jeffh@ActiveState.com>

        * library/init.tcl: make sure env(COMSPEC) on Windows is executed
        with the right case, as it may otherwise fail inexplicably.

2001-12-28  Don Porter <dgp@users.sourceforge.net>

        * generic/tclCkalloc.c (MemoryCmd, TclFinalizeMemorySubsystem):
        Added the [memory onexit] command, intended to replace [checkmem].

        * doc/DumpActiveMemory.3: 
        * doc/memory.n: Updated documentation for [memory] and related
        matters.  [Bug 487677]

        * mac/tclMacBOAMain.c (Tcl_Main, CheckmemCmd): Removed all the
        machinery for the [checkmem] command that is completely duplicated
        by code in generic/tclCkalloc.c.

        * generic/tclBinary.c:
        * generic/tclListObj.c:
        * generic/tclObj.c:
        * generic/tclStringObj.c: Removed references to [checkmem] in
        comments, referencing [memory active] instead, since it is
        documented.

2001-12-28  Daniel Steffen <das@users.sourceforge.net>

        * mac/tclMacInit.c:
        * mac/tclMacTclCode.r: synced up tclInit features to unix/win:
        implemented TclSetPreInitScript support, use of existing tclInit 
        proc if defined, check of default encoding dir if set. Changed
        script library resource names to lowercase (i.e. same as
        corresponding files). Used Tcl_JoinPath instead of string append.
        Check that system encoding could be loaded before utf translating
        the LibraryPath.
        * mac/tclMacApplication.r:
        * mac/tclMacLibrary.r:
        * mac/tclMacOSA.r:
        * mac/tclMacResource.r: minor version resources cleanup

2001-12-21  Mo DeJong  <mdejong@users.sourceforge.net>

        * unix/tcl.m4 (SC_PATH_TCLCONFIG, SC_PATH_TKCONFIG):
        Search for config file using exec_prefix instead of
        prefix when no --with-tcl or --with-tk argument is used. [Bug 492418]

2001-12-21  Daniel Steffen <das@users.sourceforge.net>

        * unix/tcl.m4: fixed incorrect SHLIB_LD_LIBS
        setting for MacOSX / Darwin.
        * unix/configure: Regen.
        * unix/mkLinks.tcl: improved case-insensitive
        filesystem support.
        * unix/mkLinks: Regen.

2001-12-19  Don Porter <dgp@users.sourceforge.net>

        * unix/Makefile.in (dist): corrected use of eolFix.tcl on
        working files.  It should operate on distributed files.  [Bug 495120]

2001-12-19  David Gravereaux <davygrvy@pobox.com>

        * tools/tcl.wse.in: Fix for #495120.  tcl.wse.in was
        stored in cvs with improper <eol>.  This resulted in
        corrupted <eol> when checked-out on translating CVS
        clients such as windows (CRCRLF) and mac (CRCR).

2001-12-19  Mo DeJong  <mdejong@users.sourceforge.net>

        * unix/configure:
        * unix/tcl.m4 (SC_CONFIG_CFLAGS): Update
        SunOS 5.[0-6] target so that correct linker
        options are passed to gcc or ld. [Tk Bug 220863]

2001-12-19  Mo DeJong  <mdejong@users.sourceforge.net>

        * unix/README: Update to account for changes
        in the unix/dltest directory, the way autoconf
        is run, and the new "make shell" target.

2001-12-19  Mo DeJong  <mdejong@users.sourceforge.net>

        * unix/Makefile.in: Rename dltest to dlpkgs to
        fix problem where lib files were not getting
        built because dltest/ directory already existed.

2001-12-19  Jeff Hobbs  <jeffh@ActiveState.com>

        * win/tclWinSerial.c (SerialCheckProc): corrected time
        calculations to be unsigned. (schroedter)

2001-12-18  Mo DeJong  <mdejong@users.sourceforge.net>

        * unix/Makefile.in: Define new dltest target that
        simply does a cd to dltest/ before running make.
        There is no need for the separate configure
        script that was previously being used.
        * unix/configure: Regen.
        * unix/configure.in: Subst into dltest/Makefile.
        * unix/dltest/Makefile.in: Define LIBS using
        DL_LIBS, LIBS, and MATH_LIBS variables instead
        of TCL_LIBS variable from tclConfig.sh.
        * unix/dltest/README: Update readme to account for new
        configure free implementation.
        * unix/dltest/configure: Removed.
        * unix/dltest/configure.in: Removed.

2001-12-18  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * generic/tcl.h (TCL_STUB_MAGIC): Added cast to force type to be
        an int and get rid of a persistent and pointless warning with
        SunPro compiler.

        * generic/tclCkalloc.c (Tcl_AttemptDbCkalloc,Tcl_AttemptDbCkrealloc): 
        * generic/tcl.decls (Tcl_AttemptDbCkalloc,Tcl_AttemptDbCkrealloc):
        Made the file parameters to these functions into CONST char *,
        like they always should have been to match the other Tcl*Db* API
        functions.

2001-12-17  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

        * Applied #219311 on behalf of Rolf Schroedter
          <schroedter@users.sourceforge.net> to prevent fcopy on serial
          ports from flooding the event queue.

2001-12-11  Miguel Sofer  <msofer@users.sourceforge.net>

        * doc/CrtInterp.3:
        * generic/tclBasic.c: docs and comments corrections [Bug 493412]
        Bug & patch by Don Porter.  

2001-12-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * win/tclWinNotify.c (Tcl_FinalizeNotifier): Stop Tcl on Windows
        from crashing when shutdown from a non-Tcl thread. Fixes Bug
        #217982 [orig. 5804] reported by Hugh Vu and Gene Leache.   I'm
        not convinced that the shutdown process is right even with this,
        but it was definitely wrong without...

2001-12-13  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

        * win/tclWinSock.c (TcpGetOptionProc): Fix for tcl bug item
          #478565 reported by an unknown person. Bypasses all calls to
          "gethostbyaddr" for address "0.0.0.0" to prevent delays on
          Win/NT.

2001-12-12  Jeff Hobbs  <jeffh@ActiveState.com>

        * doc/Preserve.3: doc'd TCL_DYNAMIC use. [Patch #483989] (porter)

2001-12-12  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

        * generic/tclIO.c (Tcl_GetsObj): Applied patch for bug #491341 as
          provided by Don Porter <dgp@users.sourceforge.net>. Fixes the
          assumption of having an empty Tcl_Obj to work with.

2001-12-11  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclCompCmds.c:
        * generic/tclCompile.c:
        * generic/tclExecute.c: consistency patch, to make all
          instructions that pop a variable number of Tcl_Obj's off the
          execution stack take the number of popped objects as first
          operand. Modified *only* the new instructions
          INST_LIST_INDEX_MULTI and INST_LSET_FLAT, so this has no effect
          on bytecodes generated up to tcl8.4a3 inclusive.

        * generic/tclExecute.c: fix debug messages in INST_LSET_LIST. 

        * generic/tclCompCmds.c (TclCompileLindexCmd):
        * generic/tclCompExpr.c (CompileMathFuncCall): removed the last
          two overestimates of the necessary stack depth for bytecodes in
          the fix of [Bug 483611].

2001-12-10  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

        * unix/tclUnixPipe.c (TclpCreateProcess): Applied Don Porter's
          patch fixing bug #437489.

2001-12-10  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclEvent.c:
        * tests/event.test: fix background error reporting in the absence
        of a bgerror proc [Bug 219142].

2001-12-10  Don Porter <dgp@users.sourceforge.net>

        * doc/Access.3:
        * doc/CrtChannel.3:
        * doc/DString.3:
        * doc/ExprLong.3:
        * doc/FileSystem.3:
        * doc/GetStdChan.3:
        * doc/OpenFileChnl.3:
        * doc/StdChannels.3:
        * doc/TCL_MEM_DEBUG.3:
        * doc/Tcl_Main.3:
        * doc/Utf.3:
        * doc/file.n:
        * doc/tclsh.1:  Several typo and formatting corrections discovered
        during conversion to TMML.  Thanks to Joe English.  [Patch 490514]
        * unix/mkLinks: 'make mklinks'

2001-12-10  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclCompCmds.c:
        * generic/tclCompExpr.c:
        * generic/tclCompile.c:
        * generic/tclCompile.h:
        * generic/tclExecute.c:
        * generic/tclProc.c: fixed the calculation of the maximal stack
        depth required by bytecodes [Bug 483611].

2001-12-07  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclVar.c: 
        * tests/trace.test: restored consistency in refCount accounting by
        array traces [Bug #4484339], submitted by Don Porter. 

2001-12-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/parseExpr.test, tests/for.test, tests/expr.test:
        * tests/expr-old.test, tests/compile.test, tests/compExpr.test
        * tests/compExpr-old.test: Kept up to date with syntax errors.
        * generic/tclParseExpr.c (ParsePrimaryExpr): Rewrote to give even
        better syntax errors in the fairly common case of an identifier
        without decorations by guessing based on the currently available
        functions.  Also made messages consistent between memdebug and
        ordinary builds.

2001-12-05  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclVar.c: 
        * tests/trace.test: new algorithm for [array get], safe when there
        are traces that modify the array [Bug #449893]. 

2001-12-04  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/compExpr-old.test, tests/compExpr.test, tests/compile.test: 
        * tests/expr-old.test, tests/expr.test, tests/for.test: 
        * tests/while.test, tests/if.test: Rewrite to handle more specific
        syntax errors.
        * tests/parseExpr.test: Rewrite to get rid of dup test numbers and
        handle more specific syntax errors.
        * generic/tclParseExpr.c (LogSyntaxError): Added a detail message
        argument to help explain what the syntax error is.
        (Tcl_ParseExpr, ParseCondExpr, ParsePrimaryExpr): Added detail
        messages.
        (UNKNOWN_CHAR): New lexeme for characters that are always illegal
        in expressions outside strings.

2001-12-03  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * doc/expr.n: Various documentation improvements in relation to
        the function calls.  Includes fix for Bug #487704 submitted by
        Devin Eyre.

2001-12-03  David Gravereaux <davygrvy@pobox.com>

        * win/makefile.vc: Some install target bugs repaired along with
        $(TCLSTUBLIB) added to the dependencies rather than implicit through
        the dde and reg extensions which don't happen to always require it
        for some build types.

2001-11-30  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclVar.c: Tcl_Preserve'ing VarTrace structures to avoid 
        memory corruption. Patch for [Bug: 484334] provided by Don Porter 

2001-11-29  Miguel Sofer  <msofer@users.sourceforge.net>

        * tests/namespace.test: modified namespace-41.2, added 41.3
        {knownbug} after discussion with Don Porter and Kevin Kenny.

2001-11-29  Miguel Sofer  <msofer@users.sourceforge.net>

        * tests/namespace.test: added namespace-41.2, a simpler test for
        [Bug: 231259]

2001-11-29  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * generic/tclBinary.c (BINARY_SCAN_MAX_CACHE, Tcl_BinaryObjCmd,
        ScanNumber): Added caching scheme to reduce number of object
        allocations when doing scans of large repetitive binary strings.
        See comments in file for reasoning behind implementation.
        Suggested by Miguel Sofer in Patch #429916, but independently
        implemented.

2001-11-28  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * doc/regsub.n, doc/regexp.n: Converted dangling references to
        METASYNTAX section into references to the re_syntax manual page.

2001-11-27  D. Richard Hipp   <drh@hwaci.com>

        * win/tclWinFCmd.c: Fix a coredump in the filename normalizer
        code for Win95/98.

2001-11-27  David Gravereaux <davygrvy@pobox.com>

        * win/makefile.vc: Removed the Tk reference for the 'winhelp' target.
        Converge at install will need to be the solution for Tk and all other
        extensions.

2001-11-27  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/cmdAH.test (cmdAH-24.2): Made test less sensitive to OS
        preemption, but perfection isn't practical [Bug 463189, reported
        by Don Porter.]

        * tests/switch.test (switch-9.*): Added tests to exercise more of
        the argument checking.  (switch-7.2,switch-7.3): Test changed
        behaviour slightly.
        * generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Reworked argument parsing
        to be stricter about what it accepts.  This should make uses of
        the [switch] command be more maintainable.  [Bug 475397, reported
        by Don Porter.]

2001-11-26  Don Porter <dgp@users.sourceforge.net>

        * generic/tclIntPlatDecls.h: 'make genstubs' after changes
        in 2001-11-23 commit from Daniel Steffen.

2001-11-24  Mo DeJong  <mdejong@users.sourceforge.net>

        * unix/Makefile.in: Add comments to better describe
        TCL_EXE and when it should be available.
        * win/Makefile.in: Add TCL_EXE variable to be used
        by rules like `make genstubs`. Don't set TCL_LIBRARY
        before running `make genstubs` since we will be running
        with a tclsh from the PATH not the one we build.

2001-11-24  Mo DeJong  <mdejong@users.sourceforge.net>

        * win/configure: Regen.
        * win/tcl.m4 (SC_CONFIG_CFLAGS): Add comctl32.lib
        to wish link libs. This change was originally added
        to Tk on 2001-11-09 but was not committed to Tcl.

2001-11-23  Daniel Steffen <das@users.sourceforge.net>

        * unix/Makefile.in:
        * unix/configure.in:
        * unix/install-sh:
        * unix/mkLinks:
        * unix/mkLinks.tcl:
        * unix/tclLoadDyld.c:
        * unix/tclMtherr.c: Mac OSX support: build system, dynamic code loading
        and support for case-insensitive filesystems in mkLinks (patch #435258)

2001-11-23  Daniel Steffen <das@users.sourceforge.net>

        Up-port to 8.4 of mac code changes for 8.3.3 & various new
        changes for 8.4, some already backported to 8.3.4 (patch #435658)

        * generic/tclObj.c: added #include to fix missing prototype errors

        * generic/tcl.h: MAC_TCL: addition of ConditionalMacros.h and use of
        DLLIMPORT and DLLEXPORT like on other platforms.  ( => no longer need
        the .exp files and can remove use of #pragma export that never worked
        well)
        removed line continuation in #if clause as this breaks the mac
        resource compiler (note that *.r files include tcl.h)

        * mac/tclMacFile.c: fixed bug in permission checking code

        * mac/tclMacLoad.c: corrected utf8 handling, comparison of
        package names to code fragment names changed to only match on the
        length of package name, this allows for fragment names with version
        numbers appended

        * mac/tclMacInt.h:
        * generic/tclInt.h:
        * mac/tclMacTime.c:
        * generic/tclIOUtil.c: moved declaration of TclpGetGMTOffset()

        * mac/tclMacShLib.exp:
        * mac/tclMacOSA.exp:
        * mac/tclMacMSLPrefix.h: removed files

        * unix/Makefile.in: removed reference to .exp files

        * mac/MW_TclBuildLibHeader.h:
        * mac/MW_TclBuildLibHeader.pch:
        * mac/MW_TclHeaderCommon.h:
        * mac/MW_TclStaticHeader.h:
        * mac/MW_TclStaticHeader.pch: new precompiled header files

        * mac/MW_TclAppleScriptHeader.pch:
        * mac/MW_TclHeader.pch:
        * mac/MW_TclTestHeader.pch:
        * mac/tclMacCommonPch.h: revised precompiled header handling: now
        include a common header file 'MW_TclHeaderCommon.h' from all .pch
        files, the .pch files themselves now only setup #defines (e.g.
        BUILD_tcl, STATIC_BUILD, TCL_DEBUG, TCL_THREADS) like in makefiles on
        other platforms.

        * mac/tclMac.h:
        * mac/tclMacPort.h:
        * mac/tclMacInt.h: use of BUILD_tcl and TCL_STORAGE_CLASS like on other
        platforms, standardize #include'd files to what's done on other
        platforms, removed use of #pragma export.

        * mac/tcltkMacBuildSupport.sea.hqx: new archive of mac build support
        files & suggested build environment directory hierarchy: 
        'Building MacTclTk' & 'CW Pro6 changes' readme's.
        projects for MoreFiles 1.5.2 static & shared libraries.
        project & sources for 'pseudoCarbonSupport', see below.
        included XML versions of the projects for CW Pro5 or Pro7 users.

        * mac/tclMacProjects.sea.hqx: updated mac build project files:
        build support for CodeWarrior Pro6, UnivIntf 3.4 & shared runtime
        libraries: the MSL libraries and MoreFiles are no longer compiled into
        Tcl.shlb, all non-static binaries now use the Pro6 shared runtime
        libraries and MoreFiles.shlb.  These shlbs are merged into the standard
        Wish and TclShell, but 3rd party applications linking with Tcl.shlb or
        Tk.shlb need to setup access to them.  (see the "(sh-ppc)" targets
        for how to do this.)
        included XML versions of the projects for CW Pro5 or Pro7 users.
        use compat/strtod.c instead of MSL's strtod()
        use WASTE versions of MSL for tcl test target to avoid text buffer
        cutoff at 32k.
        Merging the full MSL.shlb and the other shlbs into Wish & TclShell
        makes them a bit larger than before, use unmerged binaries to avoid
        copying the shared code with every application, e.g. when deploying
        numerous Wish based droplets.
        Note that using CW Pro5 to compile extensions is in principle still
        possible, but need to link with Pro6 runtime libraries.
        Tclapplescript now loads and runs on CFM68k.
        Highly experimental "pseudoCarbon" support for Tcl only on OS 8/9:
        binaries in "Build:(Carbon):" link against CarbonLib instead of
        InterfaceLib, however the actual code has not been carbonized! i.e. it
        will not run on OSX and may not even run properly with CarbonLib. 
        This should in principle allow you to build & test OS9 CFM Carbon
        binaries that need to link with Tcl.shlb.  On OSX you can use the
        native Tcl.framework, but you have to build a MachO binary as there
        is no CFM glue lib for Tcl.framework.
        the library pseudoCarbonSupport.shlb manually loads the symbols
        from InterfaceLib that are not in CarbonLib but are needed by the
        uncarbonized code in Tcl.shlb and TclShell.

        * generic/tclMain.c: MAC_TCL: workaround for broken/non-standard isatty
        on MW Pro6, #include <unistd.h> instead of defining isatty

        * mac/tclMacPort.h: MW Pro6 changes for MSL fcntl.h, stat.h & isatty

        * mac/tclMacAppInit.c: add EXTERN to InstallConsole to enable DLL
        export via the TCL_STORAGE_CLASS mechanism.

        * mac/tclMacFCmd.c: fix for FSpDirectoryCopy API change

        * mac/tclMacLibrary.c: emit compile time error when
        TCL_REGISTER_LIBRARY and USE_TCL_STUBS are both defined at the same
        time in an extension, this use is not currently supported and will
        result in a crash when dynamically loading the extension.

        * mac/tclMacApplication.r:
        * mac/tclMacLibrary.r:
        * mac/tclMacOSA.r:
        * mac/tclMacResource.r: fixed obsolete copyrights/dates in version
        strings; updated version strings to standard usage; added support for
        '(Support Libraries)' subfolder for shared runtime libraries in
        unmerged binaries; commented out demo setting of "Tcl Environment
        Variables"; reorganized resources among these files to avoid 
        multiple copies in applications and shared libraries, the script
        libraries are now no longer duplicated in Tclsh but are only included 
        in the resources of Tcl.shlb.

        * mac/tclMacChan.c:
        * mac/tclMacSock.c: cast for *BlockMode

        * mac/tclMacUtil.c:

        * mac/tclMacOSA.c:
        * mac/tclMacUtil.c:
        * generic/tclThreadTest.c: renamed routines conflicting with standard
        Apple or MoreFiles headers (at compile or link time):
        GetGlobalMouse         -> GetGlobalMouseTcl
        FSpGetDirectoryID      -> FSpGetDirectoryIDTcl
        FSpOpenResFileCompat   -> FSpOpenResFileCompatTcl
        FSpCreateResFileCompat -> FSpCreateResFileCompatTcl
        NewThread              -> NewTestThread
        the renamed MoreFiles *Tcl routines are just wrappers calling into the
        MoreFiles DLL.

        * mac/tclMacCommonPch.h:
        * mac/tclMacThrd.c:
        * mac/tclMacPanic.c: removed OLDROUTINENAMES define, renamed obsolete
        apple API names to modern equivalents; UH3.4 support: added #include
        <ControlDefinitions.h>, updated New*Proc() calls to New*UPP().

        * mac/tclMacUnix.c: added missing (Tcl_Obj ***) cast to
        Tcl_ListObjGetElements call

        * mac/tclMacAlloc.c: modernized TclpSysAlloc() to use temporary
        memory instead of system heap memory when available (MacOS
        >= 7.5 and possibly earlier, use of system heap has been
        discouraged for a long time and has many disadvantages, e.g. memory
        isn't paged out, and errors can very easily bring the system down);
        fixed crashing bug in TclpSysRealloc() and CleanUpExitProc() where
        memory was being accessed after having been deallocated; fixed
        memory leak in (de)allocation code (for every block ever allocated
        with TclpSysAlloc, a Ptr was leaked), if temporary memory is
        available, don't track allocated memory, instead use
        RecoverHandle() to get Handle from Ptr, otherwise use doubly linked
        list to correctly track memory and free all allocated memory; added
        new option for ConfigureMemory: MEMORY_DONT_USE_TEMPMEM, disables
        use of temporary memory even when it would be available, only
        necessary when writing e.g. a driver (using tcl??); increased
        fraction of application heap reserved for OS routines to 512K

        * compat/strftime.c: 
        * mac/tclMacTime.c:
        * mac/tclMacPort.h:
        * generic/tclInt.decls: 
        * generic/tclIntPlatDecls.h:
        * generic/tclStubInit.c: timezone support for mac via 
        TclpGetTZName() like on windows, using an inverse timezone table
        adapted from tclDate.c to map gmtoffset in seconds gotten from
        the MacOS APIs to a  timezone string, as there is no good way to get
        this info from MacOS. I had to make up some unusual timezones and
        arbitrarily decide on the most standard of the multiple choices
        available for every timezone.

        * generic/tclExecute.c: workaround for a MSL bug/misfeature: for
        very small floats, MSL can return errno ERANGE but a
        non-zero value ( < LDBL_MIN however)
        
        * mac/tclMacAppInit.c: support for WASTE text library using
        temporary memory, setting has no effect if WASTE is not used.
        
        * mac/tclMacPanic.c: removed duplicate code from generic/tclPanic.c
        and added that file to projects instead.

        * tests/all.tcl: set tcltest::singleProcess 1 as multiple processes
        are not available on the mac.
        
        * tests/cmdAH.test: access time not available on the mac, skip the 
        atime touch test

        * generic/tclBasic.c (Tcl_DeleteCommandFromToken,CallCommandTraces):
        * generic/tclCmdMZ>c (Tcl_UntraceCommand):  Added Tcl_Preserve and
        Tcl_Release calls to prevent deletion of CommandTrace structures
        until all callers are done using them, preventing memory corruption.

        to the Stubs table and the library documentation.  Added a
        TclpGetTime in tclUtil.c for backward compatibility of
        extensions. [Patch #483500, TIP#73]

        * generic/tclCmdMZ.c (Tcl_TimeObjCmd): Corrected an error in the

        * generic/tclBasic.c
        * generic/tclCompile.h: 
        * generic/tclExecute.c: moving all code relative to bytecodes from
        tclBasic.c to tclExecute.c - the functions RecordTracebackInfo and
        Tcl_ExprObj went to tclExecute.c, and new interface function was
        defined (TclCompEvalObj).
        The final objective of this sequence of moves is to provide a
        clean, clear-cut interface between Tcl's core and the
        compiler/engine subsystem.  

2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclBasic.c
        * generic/tclCompile.h: 
        * generic/tclExecute.c: factoring out of common code in tclBasic.c
        (new function TclInterpReady defined: it resets the interp's
        result, then checks that it hasn't been deleted and that the
        nesting level is acceptable). Passed the responsibility of calling
        it to the *callers* of TclEvalObjvInternal.

2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclBasic.c
        * generic/tclExecute.c: a better variant of the previous-to-last
        commit (restoring numLevels computations). The managing of the
        levels now has to be done by the *callers* of TclEvalObjvInternal  

2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclExecute.c: missing variable declaration under
        TCL_COMPILE_DEBUG. 

2001-11-20  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclExecute.c:
        * generic/tclProc.c: restoring the computations of iPtr->numLevels
        to the original logic (previous to buggy modifs on 2001-11-16).

2001-11-20  Jeff Hobbs  <jeffh@ActiveState.com>

        * tools/eolFix.tcl (new-file):
        * unix/Makefile.in: added EOL correction for Windows bat files to
        dist target. [Bug #219409] (davygrvy)

        * unix/tclUnixInit.c (TclpSetInitialEncodings): update of patch
        from 2001-11-16 that uses the old Tcl encoding check mechanism as
        a fallback to the original.  Also added a TCL_DEFAULT_ENCODING
        #define (defaults to iso8859-1).  Tcl will first try setlocale and
        nl_langinfo, and if that fails, guess based on certain LANG|LC_*
        env vars. [Patch #418645]

2001-11-19  David Gravereaux <davygrvy@pobox.com>

        * win/buildall.vc.bat:  Added useful comments.

        for Win95/98, and clarified docs on differences in file
        normalization between NT/2000 and the older operating systems.
        Added test to ensure normalization is correct.
        
2001-11-19  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclBasic.c:
        * generic/tclParse.c: Code reorganisation. Moved all evaluation
        functions from tclParse.c to tclBasic.c, so that now tclParse.c
        deals exclusively with parsing and all evaluations are done by
        code in tclBasic.c. The functions moved are: TclEvalObjvInternal,
        Tcl_EvalObjv, Tcl_LogCommandInfo, Tcl_EvalTokensStandard,
        Tcl_EvalTokens, Tcl_EvalEx, Tcl_Eval, Tcl_EvalObj and
        Tcl_GlobalEvalObj. 

2001-11-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/trace.test (trace-8.8): Added adapted version of Bug
        #219393 as new test; the test won't reliably show up the old
        problem unless it is being run under something like Purify, but
        something is better than nothing...

        * generic/tclVar.c (Tcl_TraceVar2, Tcl_UntraceVar2): Added missing
        mask bits for trace result type and a check for a nonsense flag
        combination.
        * generic/tclCmdMZ.c (TraceVarProc): Added missing test for NULL
        when deleting a trace that doesn't cause an error.

        * doc/TraceVar.3: Added documentation for change due to TIP#68.

        * generic/tclCmdMZ.c (TraceVarInfo): Removed problematic errMsg
        field from structure.
        (TraceVarProc): Removed references to errMsg field and changed
        handling of errors so that they returned a Tcl_Obj* containing the
        error string.  This minimizes the number of calls to the memory
        management subsystem.
        (TclTraceCommandObjCmd, TraceCommandProc): Removed references to
        errMsg field which was never used in command traces in any case.
        (Tcl_TraceObjCmd, TclTraceVariableObjCmd): Removed references to
        errMsg field and made variable traces register with
        TCL_TRACE_RESULT_OBJECT bit set.

        * generic/tcl.h (TCL_TRACE_RESULT_DYNAMIC,TCL_TRACE_RESULT_OBJECT): 
        New constants to define how to handle the strings returned from
        trace callbacks [TIP#68]
        * generic/tclVar.c (CallTraces, Tcl_GetVar2Ex, TclGetIndexedScalar,
        TclGetElementOfIndexedArray, Tcl_SetVar2Ex, TclSetIndexedScalar,
        TclSetElementOfIndexedArray, Tcl_UnsetVar2, Tcl_ArrayObjCmd,
        TclDeleteVars, TclDeleteCompiledLocalVars, DeleteArray,
        TclVarTraceExists): Support for those new trace flags.

        * unix/configure: regened
        * unix/configure.in: added SC_ENABLE_LANGINFO call
        * unix/tcl.m4: made SHLIB_LD_LIBS='${LIBS}' for FreeBSD* (meyer)
        Added modified version of Wagner patch to make use of nl_langinfo
        where possible to determine Unix platform encoding, instead of the
        inflexible built-in system.  This is used by default when
        possible, and can be disabled with --enable-langinfo=no.

        code for tclCmdNameType objects to tclObj.c (from tclExecute.c). 
        This code has nothing to do with bytecodes.

        * win/makefile.vc:
        * win/tcl.dsp:  winhelp target fixes for non-NT systems.  It
        seems NMAKE under these remembers changed directories during

        <peter.spjuth@space.se> to specify a pattern file from the
        commandline and redirecting output to a file when not under
        NT with it's scrollback console.  Then it replays it, piped
        through more.  Added 2 new static "configurations" to tcl.dsp.
        I could keep adding more, but I think we should leave it up to
        the user for customizing it.

        * win/makefile.vc:  Fixed install target to adjust for the
        different build types.  Added a 'linkexten' option to link the
        win extensions inside the shell when built static.  Placed
        win/tclAppInit.c patch in SF patch DB for approval. 'profile'
        option not hooked in yet.  Everything else know is done.

        * win/tcl.dsp(new):
        * win/tcl.dsw(new):  Simple MsDev stub project files that calls
        makefile.vc.  Will help run Tcl in the debugger easier without
        confusing MsDev for where the .pdb files are.

2001-11-07  Mo DeJong  <mdejong@users.sourceforge.net>

        * unix/Makefile.in:
        * win/Makefile.in:
        Print a message indicating that the user should
        run "make genstubs" when the generated tclStubInit.c
        file is out of date. We can't regenerate automatically
        since there may be no tclsh on the system and that
        would cause bootstrap problems. [Tcl bug 465874]

2001-11-07  Mo DeJong  <mdejong@users.sourceforge.net>

        Define TCL_INCLUDE_SPEC in tclConfig.sh. It should be
        included by extensions that need to find Tcl include
        headers in the install location. The user can override
        the include install dir with --includedir so we need
        to record this information for extensions. [Tcl bug 421835]
        
        * unix/configure: Regen.
        * unix/configure.in: Define TCL_INCLUDE_SPEC.
        * unix/tclConfig.sh.in: Define TCL_INCLUDE_SPEC.
        * win/configure: Regen.
        * win/configure.in: Define TCL_INCLUDE_SPEC.
        * win/tclConfig.sh.in: Define TCL_INCLUDE_SPEC.

2001-11-07  David Gravereaux <davygrvy@pobox.com>

        * win/rules.vc:
        * win/makefile.vc: Dropped the NOMSVCRT macro and put it on the
        option list instead.  It makes more sense to me this way as
        NOMSVCRT=0 would only be the valid setting.  Fixed the dde and reg
        extension for building static.  Improved, but not perfected, the
        winhelp target.

2001-11-07  Mo DeJong  <mdejong@users.sourceforge.net>

        * win/README: Change minimum VC++ version to 5.X since
        4.X is known not to work.
        Indicate that Mingw is required and building with Cygwin
        gcc is not supported. Include instructions that indicate
        how to install Mingw and what URLs folks should use to
        download the supported version of Mingw.
        * win/configure: Regen.
        * win/configure.in: Error out if user tries to compile the
        Windows version of Tcl with Cygwin gcc. Users should compile
        with Mingw gcc instead.

2001-11-06  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

        * generic/tclIO.c (ReadChars): Fixed bug #478856 reported by
          Stuart Cassoff <stwo@users.sourceforge.net>. The bug caused loss
          of fileevents when [read]ing less data from the channel than
          buffered. Due to an empty input buffer the flag
          CHANNEL_NEED_MORE_DATA was set but never reset, causing the I/O
          system to wait for more data instead of using a timer to
          synthesize fileevents and to flush the pending data out of the
          buffers.

2001-11-06  David Gravereaux <davygrvy@pobox.com>

        * win/rules.vc (new):
        * win/makefile.vc:  Complete over/under rewrite to support numerous
        build options all from the commandline itself without needing to
        edit the makefile.  Now requires vcvars32.bat to be run prior to
        running nmake for bootstraping the environment.  Fully doc'd usage
        for it is in makefile.vc.  Commentary welcome.  Sticky points left
        are:

        1) winhelp target shows errors in the converting script.
        2) .rc scripts aren't getting the right #defines to build the correct
           "OriginalFilename" strings. (have patch, won't commit yet)
        3) Naming convention with suffixes describing the buildtype are 'tsdx'
           which will need public acceptance. ie. tclsh84tsx.exe is a (t)
           threaded shell (s) statically linked to the core and (x) uses
           msvcrt instead of libcmt.

2001-11-04  Vince Darley  <vincentdarley@users.sourceforge.net>

        * library/init.tcl: made filesystem fallback proc
        ::tcl::CopyDirectory more robust to vagaries of non-native
        filesystems.
        
2001-11-02  Vince Darley  <vincentdarley@users.sourceforge.net>

        * doc/file.n:
        * generic/tclIOUtil.c: updated documentation and comments
        to clarify behaviour of 'file copy' wrt soft links.
        
2001-10-29  Vince Darley  <vincentdarley@users.sourceforge.net>

        * win/tclWinFile.c: fix to '-types {f r}' bug in
        TclpMatchInDirectory (which could cause a UMR, as well as
        returning wrong results).  Also improved API for 'stat'
        to resolve [Bug#219258].
        * win/tclWin32Dll.c
        * win/tclWinInt.h: addition of improved stat API to internal 
        lookup table.
        * tests/fileName.test: two new tests for the above bug.
        * generic/tclIOUtil.c: some cleanup of comments and #ifdefs
        
2001-10-29  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * unix/tclUnixFile.c (TclpMatchInDirectory): Argument to access()
        was entryPtr->d_name instead of nativeEntry which failed when
        trying to check access for files in other than the current
        directory. [Bug 475941, reported by Georgios Petasis]

2001-10-25  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * unix/tclUnixChan.c: Added stateUpdated member to struct TtyState.
        (TtyCloseProc,TtySetOptionProc,TtyInit): Use stateUpdated member
        of TtyState to decide whether it is necessary to reset a serial
        port when Tcl closes it.  Blindly resetting can cause Tcl to be
        sent an unexpected SIGTSTP when it is executing in the background
        [Bug 471374, reported by Chris Nelson]

2001-10-22  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

        * doc/ObjectType.3: Minor documentation fix, reported by David
          N. Welton <davidw@users.sourceforge.net> directly to me.

2001-10-22  Vince Darley  <vincentdarley@users.sourceforge.net>

        * win/tclWinFCmd.c: fix to stop test suite from hanging process
        under some versions of WinNT. [Bug #466102] (Kevin Kenny)
        
2001-10-18  Jeff Hobbs  <jeffh@ActiveState.com>

        * tests/clock.test (clock-8.1): 
        * generic/tclDate.c (RelativeMonth): 
        * generic/tclGetDate.y (RelativeMonth): corrected off-by-one-day
        error in clock scan with relative months and years during swing
        hours. [Bug #413397, Patch #414024] (lavana)

2001-10-18  Vince Darley  <vincentdarley@users.sourceforge.net>

        * generic/tclIOUtil.c: fix to bug in Tcl_FSChdir shown up
        by recent tclkit builds.

2001-10-17  Jeff Hobbs  <jeffh@ActiveState.com>

        * unix/tclUnixPipe.c (PipeInputProc, PipeOutputProc): do immediate
        retry when error is returned with errno == EINTR.
        [Bug #415131] (leger)

2001-10-16  Jeff Hobbs  <jeffh@ActiveState.com>

        * unix/tclLoadAout.c (TclGuessPackageName): removed unused vars
        and fixed warnings. [Bug #446622] (lim)

2001-10-15  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclProc.c: changing a memcmp to strncmp to avoid a memory
        error detected by purify (thanks Jeff); modify style to agrre with
        the style guide. 
        
2001-10-15  Andreas Kupries  <andreas_kupries@users.sourceforge.net> 

        * generic/tclInt.decls (TclExpandCodeArray,TclGetInstructionTable):
          Added to internal stubs table. Tclcompiler (Tclpro project)
          needs them if used as loadable package under Windows. Changed
          signatures. We don't want to describe compiler internal
          structures in "tclInt.h".

        * generic/tclCompile.h: S.a. Removed function declarations.
        * generic/tclCompile.c: S.a. Adapted to changed signatures.

2001-10-15  Jeff Hobbs  <jeffh@ActiveState.com>

        * unix/configure.in: 
        * win/configure: 
        * win/configure.in: 
        * win/tcl.m4: reworked to be a little cleaner in comparison to
        each other, and to AC_SUBST even empty vars for win/tclConfig.sh

        * generic/tclFileName.c: minor code cleanup

        * generic/tcl.h: moved #define of WIN32 to tcl.h where __WIN32__
        is defined and added #ifndef check.

        * doc/open.n: moved all fconfigure option docs to fconfigure.n
        * doc/fconfigure.n: added serial config options

2001-10-12  Jeff Hobbs  <jeffh@ActiveState.com>

        * library/encoding/ebcdic.enc:
        * tools/encoding/ebcdic.txt: EBCDIC charset mapping.
        [Patch #219323] (nijtmans)

        * library/encoding/tis-620.enc:
        * tools/encoding/tis-620.txt: TIS-620 charset mapping.
        [Patch #467423] (poonlap)

        * tests/http.test: added removeFile for outdata

        * tests/ioCmd.test: added catch around file removal, as Windows
        file locking throws errors.

        * tests/socket.test (socket-7.2): corrected to work on Win2K.

2001-10-12  Miguel Sofer  <msofer@users.sourceforge.net>
        
        * tests/compile.test: new tests for [Bug 467523]; they are only
        effective if TCL_MEM_DEBUG was set during compilation.

2001-10-11  Miguel Sofer  <msofer@users.sourceforge.net>
        
        * generic/tclLiteral.c (TclReleaseLiteral): insured that
        self-referential bytecodes are properly cleaned up on interpreter
        deletion [Bug 467523] (Ronnie Brunner)

2001-10-10  David Gravereaux  <davygrvy@pobox.com>

        * win/tclWinPort.h:  #include <winsock2.h> needed to get moved
        to after #include <windows.h> or wierd misunderstandings took
        place when -D_WIN32_WINNT=0x0400 is set for outside code that
        requires knowledge of Tcl innards.  General header macro magic
        applied liberally...

2001-10-10  Don Porter  <dgp@users.sourceforge.net>

        * tests/unixInit.test:  Corrected restore of ::env(LANG).

2001-10-09  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclFileName.c (Tcl_SplitPath): corrected mem leak
        intro'd with VFS code where the result obj from Tcl_FSSplitPath
        was not getting freed.

2001-10-09  Miguel Sofer  <msofer@users.sourceforge.net>
        
        * generic/tclLiteral.c: (TclReleaseLiteral) reverted previous
        patch for [Bug 467523] - cure is worse than the illness.

        Updated encodings with latest mappings from www.unicode.org.  This
        did not include some Mac encodings that have special multi-unichar
        translations now (like symbols, dingbats and japanese).  Also does
        not include big5, gb or euc* as those have different formats in
        the latest Unicode version that need new conversion tools.  Not
        all related .enc files changed as some had been updates separately.

2001-10-03  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclEvent.c (Tcl_FinalizeThread): moved freeing of
        tclLibraryPath to before the thread exit handlers are called.
        Slight modification to change on 2001-09-24.

2001-10-01  Jeff Hobbs  <jeffh@ActiveState.com>

        * win/configure: regen'ed
        * win/tcl.m4:
        * win/makefile.vc: added Win64 SDK RC1 compilation support
        * win/Makefile.in: added $(LDFLAGS_CONSOLE) to TCLSH, TCLTEST and

        * win/tclWinInit.c: minor 64bit casts

        numbers" for easier understanding.  [Bug #465674]

        * doc/fileevent.n: Accepted [Patch #465279] adding an example to
          the fileevent manpage. Minor modifications to get a better
          formatting. Report and patch by David N. Welton
          <davidw@users.sourceforge.net>.

        * The changes below fix [Bug #462317] where Expect tried to read
          more than was in the buffers and then blocked in the OS call as
          its pty channel driver provides no blockmodeproc through which
          the OS could be notified of blocking-behaviour. Because of this
          the general I/O core has to take more care than usual to
          preserve the semantics of non-blocking channels.

          The problem was reported by "Kevin O'Gorman"
          <kevin@kosmanor.com>.

        * generic/tclIO.c (Tcl_ReadRaw): Do not read from the driver if
          the channel is non-blocking and the fileevent causing the read
          was generated by a timer. We do not know if there is data
          available from the OS. Instead of going to the OS for more and
          potentially blocking we simply signal EWOULDBLOCK to the higher
          levels to cause the system to wait for true fileevents.
          (GetInput): Same as before.
          (ChannelTimerProc): Added set and clear of CHANNEL_TIMER_FEV.

        * generic/tclIO.h (CHANNEL_TIMER_FEV): New flag for channels. Is
          set if a fileevent was generated by a timer, the channel is not
          blocking and the driver did not provide a blockmodeproc. In that
          case the I/O core has to be especially careful about going to
          the driver for more data.

          already in from tclWinPort.h).

        * win/tclWinPort.h: changed winsock.h include to winsock2.h.
          Reverses change from 2000-11-16, but is necessary for WIN64.
          Extensions should comply with defined OS words, or use #ifndef.

2001-09-20  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/socket.test: removed dependence on being run from same dir

        of valuePtr in TRACE_WITH_OBJ in INST_EVAL_STK case. [Bug #462594]

        also detected at abnormal returns.

2001-09-19  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * doc/socket.n: Added documentation to mention what happens when a
        server socket is created with port=0.  Removed an old change bar,
        and no new change bar because Tcl has always behaved this way as
        it is really a poorly-documented standards-defined OS feature.

        * tests/util.test (util-8.1): Test derived from code to detect the
        problem, but the test always works in the C locale, so beware if
        you are maintaining the code.
        * generic/tclUtil.c (TclNeedSpace): Rewrote to be UTF-8 aware.
        [Bug 411825, but not that patch which would have added extra

2001-09-17  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tcl.h: removed forced #define USE_TCLALLOC 1 for
        Windows.  This means the native system allocator will be used by
        default.  This should be binary and source compatible with
        extensions, as Tcl_Alloc is a properly stubbed function.

        * tests/ioCmd.test: Changed the computation of the result for
          iocmd-8.1[123] so that the tests work for single- and
          multi-process execution of the testsuite. Depending on the
          choice of the user stdout is a tty or not and thus reports
          different channel options. Fixes [460993] reported by Don

        same duties but adheres to the standard return convention for Tcl
        evaluations; the deprecated function could only return TCL_OK or
        TCL_ERROR, which caused [Bug 219384] and [Bug 455151].
        This patch implements [TIP 56].

        Instead of checking for "$GCC" = "no" we check for
        "$GCC" != "yes" or simply swap the true and false
        blocks of code in an if statement. That way if

        * The changes below are a fix for [219253].

        * tests/socket.test: Removed _most_ instances of hardwired port
          numbers for listening sockets. Remaining are the ports in all
          tests with constraint 'doTestsWithRemoteServer'. These seem to
          be designed for a more controlled environment and are usually
          skipped when running the testsuite.

          the internal platform specific stub table.

        * win/tclWinFile.c (TclpObjStat): Now added the call to
          'TclWinFlushDirtyChannels' to this function. I don't know where
          my head was last thursday (2001-09-06), but the call was
          actually added to 'TclpObjChdir', i.e. the implementation of

        * generic/tclIOUtil.c: removed Tcl_FSCopyFile fallback
        to channel copying, since the channels will not have
        access to interpreters and the channel copying currently
        requires an interp.  Code which required cross-platform
        copies always has interpreters, so that solves the problem.

2001-09-07  David Gravereaux <davygrvy@pobox.com>

        * win/tcl.m4: Added -link50compat option so a VC6 linker makes

2001-09-07  Mo DeJong  <mdejong@users.sourceforge.net>

        * win/tclWinThrd.c (TclpThreadExit): Cast status argument to
        _endthreadex to unsigned instead of DWORD to match the Win32
        function prototype.

2001-09-06  Andreas Kupries <andreas_kupries@users.sourceforge.net>

        * All the changes below serve to fix bug [219148] which reports a
          80x performance hit for file I/O on Win* systems. On my system
          it was closer to a 120x hit. Problem report by Uwe Traum <no
          email address available>.

          The fix goes like this: The obstacle is 'FlushFileBuffers',
          executed whenever Tcl writes data to the OS, as Tcl has to wait
          for the disk to complete I/O, and disks are slow. We remove that
          obstacle. This opens another problem, [file size] reports back
          wrong numbers. So for [file size] we add the call back in. As
          optimization we keep track of the channels which were written to
          and flush only these.

        * win/tclWinFile.c (TclpObjStat): Added a call to
          'TclWinFlushDirtyChannels'. This ensures that [file size] and
          related commands report the correct size of a file even if Tcl
          has recently written to it. Unixoid OS's always report the
          correct size even for files with pending data, but Win*
          syssystem don't. They only report what is actually on disk.

        * win/tclWinInt.h: Added declaration of
          'TclWinFlushDirtyChannels', making it available to other parts
          of the tcl core.

        * win/tclWinChan.c (TclWinFlushDirtyChannels): New, internal,
          procedure. Goes through the list of open file channels and
          forces the OS to flush its file buffers for all which were
          written to since the last call of this function. This is an
          expensive operation as Tcl has to wait for the OS to complete
          actual writes to the disk.

          (FileInfo): Added dirty flag required by the procedure above.

          (FileOutputProc): Removed flushing of file buffers, setting the
          dirty flag instead. This means that the previously incurred
          delays do not happen anymore.

          (TclWinOpenFileChannel): Added initialization of 'dirty' flag.

        * doc/http.n: noted -binary, charset and coding state keys.
        * tests/http.test:
        * library/http/pkgIndex.tcl:
        * library/http/http.tcl (geturl): correctly get charset parameter
        and convert text according to specified encoding (if known).  RFC
        iso8859-1 is used by default.  Also recognize Content-encoding to
        see if we should do binary translation.  Added a CYA -binary
        switch for the cases that were missed. [Bug #219211 #219399]

        * tests/ioUtil.test: changed to make better use of constraints and
        remove knownBug constraints that weren't valid.

2001-09-06  Don Porter  <dgp@users.sourceforge.net>

        * tests/unixInit.test (unixInit-3.2): Updated test to support
          newer HP-UX releases that properly report euc-jp as the system
          encoding for Japanese.  Bug report and patch verification by Bob
          Techentin.  [Bug 453883]

        reflecting the new features just added.

2001-09-06 Vince Darley <vincentdarley@users.sourceforge.net>

        * generic/tclTest.c: tests of old-fs hooks no longer cause problems
        in threaded builds.  Also removed unused unload proc.
        * generic/tcl.decls:
        * generic/tclIOUtilc: added Tcl_FSMountsChanged so that a vfs
        can inform the filesystem that the filesystem epoch must be
        changed (since cached filesystems may now be incorrect).  Fixes
        problem running tclvfs extension.
        * library/tcltest/tcltest.tcl: if tests aren't in a native
        filesystem, then don't use pipes to run them. [Bug 458741]
        
2001-09-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * generic/tcl.decls (479 generic): 
        * generic/tclIO.c (Tcl_Seek,Tcl_Tell,Tcl_OutputBuffered): Added
        public function to return the size of the output buffer and
        reworked other channel functions to use this shared functionality
        and that of Tcl_InputBuffered() too. [TIP#49, Rolf Schroedter]

2001-09-05  David Gravereaux <davygrvy@pobox.com>

        * generic/tclPlatDecls.h:  Another small trim finalizing Borland
        support.

        * win/tclWinPipe.c:
        * win/tclWinPort.h:  More Borland compatibility fixes.  Changed
        EDQUOT #define from 49 to 69.  Borland had a clash as it was already
        using this number.  Upon advice from Helmut Giese, EDQUOT has been
        found in other header files #defined as 69.
        [Patch: 436116]

        * win/.cvsignore:  A few more glob patterns added.

        * win/makefile.bc (new):  Borland lives once more! rejoice..
        * generic/tclAlloc.c: Small Borland compatibility fix.
        * win/tclWinTime.c:  More Borland compatibility fixes.
        [Patch: 436116]

2001-09-05 Vince Darley <vincentdarley@users.sourceforge.net>

        * tests/winFCmd.test: made notWin2000 constraint false if not
        running on Windows at all.
        
2001-09-04  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinThrd.c:  Revisited _beginthreadex() stuff.  Instead
        of assuming a c-runtime implimentation of _beginthreadex normal,
        I reversed the logic to not assume, and use when is by explicitly
        needing to add runtimes that support it such as Borland.

        * generic/tcl.h:
        * generic/tclPlatDecls.h:  Borland compatibility change so
        ClientData was properly typed as a void* and TCHAR would not be
        defined twice.

        * generic/tcl.h:  Removed a small mistake from before.  Changes to
        the EXTERN macro for proper Borland compatibility will have to see
        a TIP.  What's this with the MS compiler:

                __declspec(dllexport) int func (int a, int b);

        will have to be this with Borland:

                int __cdecl __export func (int a, int b);

        The order of the attribute needs to be after the return type.

2001-09-04  Don Porter  <dgp@users.sourceforge.net>

        * compat/strtod.c (strtod):  Fixed failure to handle expressions
        like 3eq2 and failure to set errno on overflow.  [Bug 440894]

2001-09-04 Vince Darley <vincentdarley@users.sourceforge.net>

        Minor bug fixes in filesystem, plus small vfs changes as a 
        result of enabling the test filesystem to work properly.
        * tests/fileName.test: ensure new test cleans up after itself
        * doc/filename.n: 
        * generic/tclFileName.c: improved Mac path handling and document
        why [Bug: 421842] on Windows handling of UNC paths is not valid.
        Documentation and code now much clearer on what is and is not a 
        UNC path.
        * doc/FileSystem.3:
        * unix/tclUnixPipe.c:
        * generic/tclFCmd.c:
        * generic/tclIOUtil.c: fixed error message, fixed [Bug: 453512]
        about dangerous use of tmpnam, replaced with mkstemp.  
        Documented all the changes.
        * generic/tclTest.c: made test vfs fully functional as a 
        'reporting filesystem'.
        * generic/tcl.stubs:
        * generic/tcl.h:
        * generic/tclInt.h: 
        * generic/tclIOUtil.c:
        * doc/file.n:
        * various platform-specific 'TclpLoadFile': fixed comments about 
        unload behaviour, and completed objectification of loading.
        Required change to Tcl_Filesystem lookup table, so incompatible
        with 8.4a3, but not older versions of Tcl.  The change also
        allows 'link' and 'reporting' filesystems to function correctly
        when loading files.  Implementation of 'file delete -force'
        copes with case where cwd is inside the directory.  Moved
        overlooked Tcl_FSGetPathType from internal to external API.
        Made sure filesystems which are registered and then unregistered
        are only freed when all references to them are gone.
        Documented changes.
        * unix/tclUnixFCmd.c: when deleting directories recursively,
        make sure permissions are ok.  Together with the above, this
        fixes [Bug: 219139]
        * tests/winFCmd.test: differentiated test results for win2k 
        versus not.  This fixes [Bug: 219239]
        * tests/fCmd.test: added tests for 'file delete -force' where
        the cwd is inside, and when permissions are inadequate.
        
2001-09-04  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclCompile.c: fixed incorrect operands for INST_LIST
        [Bug: 458241] (David Cuthbert, dacut@users.sourceforge.net)

2001-09-03  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclExecute.c (TclExecuteByteCode): fixed missing comma
        in debug macro.

2001-09-03  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * doc/ExprLongObj.3: Fixed error in documentation of argument type
        to Tcl_ExprObj [Bug: 457435]

2001-09-02  David Gravereaux <davygrvy@pobox.com>

        * win/tclWinThrd.c:  Portability fix for Cygwin who's c-runtime,
        not surprisingly, doesn't have the MSVCRT specific _beginthreadex /
        _endthreadex pair.  This might have to be revisited for proper
        Borland, lcc32, Watcom and other support as well.
        [Patch: 444255]

        * win/tclWinThrd.c:  Moved FinalizeConditionEvent() proto to within
        the main #ifdef TCL_THREADS block to avoid mingw warning about it
        being there but unused.

        * win/makefile.vc:  Added -Zl (zee el) to tclStubLib.c compile line
        to make sure the tclstub84.lib static library is built without
        requiring a specific C-runtime library at link-time for the end-use
        developer.  It has been noted on c.l.t that this trips many first
        time users trying to make extensions.
        [Patch: 403533]

2001-08-31  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclInt.h: added TclCompileListCmd header
        * generic/tclBasic.c: added TclCompileListCmd compile proc
        * generic/tclCompCmds.c (TclCompileListCmd): function to compile
        the 'list' command at parse time.
        * generic/tclExecute.c (TclExecuteByteCode): definition of
        INST_LIST bytecode.

        * doc/StringObj.3: added words of warning to use Tcl_ResetResult
        with the Tcl_Append* functions.

        * tests/compile.test: added compile-11.* interp result checks
        * generic/tclUtil.c (TclGetIntForIndex): added Tcl_ResetResult
        before Tcl_AppendStringsToObj to prevent shared object crash when
        called from bcc instruction.  The Tcl_Append* calls that append to
        the result object that are invoked by bcc insts must remember to
        call Tcl_ResetResult because the bcc doesn't do this for us.
        [Bug #456892]

2001-08-30  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclIndexObj.c: fixed some casting problems that upset
        Crays. [Bug #419528] (andreasen)

2001-08-30  Don Porter  <dgp@users.sourceforge.net>

        * generic/tcl.h: Silence warning from Sun compiler. [Bug 454374]

2001-08-30  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclExecute.c: allow cached fully-qualified command names
        to be usable from different namespaces within the same interpreter
        without forcing a new lookup. This speeds up scripts that pass
        command names in variables ("this" in some OO packages).
        [Patch 456668]. 

2001-08-30 Vince Darley <vincentdarley@users.sourceforge.net>

        Further fs updates.  After examining the most common Tcl
        extensions (TclX, BLT, Tk, TclPro, Mktclapp), it has been
        determined that only TclpGetCwd and the Access/Stat/Open
        insert/delete hooks of the internal fs functions are ever used.
        The remaining functions from Tcl's internal interfaces have
        therefore been removed, since Tcl now exports a more suitable
        public API (Tcl_FS...)
        
        * generic/tclInt.stubs:
        * generic/tclInt.h: updated for removed internal functions.
        Some new internal functions have been put in tclInt.h (and
        not exported in the stub table because good public equivalents
        exist).
        * generic/tclTest.c: some test functions used the internal private 
        APIs.  These tests have been retained, but modified to use 
        public APIs.  Also objectified the internal filesystem tests.
        * win/tclWinFile.c: removed TclpStat, TclpAccess and refactored
        code to use NativeAccess, NativeStat.  This should speed up
        stat, access and glob commands.
        * win/tclWinFCmd.c: removed all TclpCopy/Rename/Delete 
        File/Directory string-based procedures which aren't used any more.
        Improved efficiency of some other procedures. Ensure that filename
        conversions with a NULL interp do not crash Tcl.
        * mac/tclMacFCmd.c: wrapped long lines and cleaned up
        TclpObjNormalizePath, removed all TclpCopy/Rename/Delete 
        File/Directory string-based procedures which aren't used any more.
        * mac/tclMacFile.c: removed obsolete TclpStat, TclpAccess, TclpChdir,
        etc.
        * unix/tclUnixFCmd.c: removed use of TclpAccess, removed all
        TclpCopy/Rename/Delete File/Directory string-based procedures which
        aren't used any more.
        * unix/tclUnixFile.c: removed obsolete TclpStat, TclpAccess, TclpChdir,
        etc.
        * tcl(Unix|Mac|Win)Chan.c: objectified TclpOpenFileChannel.
        * various 'load' implementations all objectified.
        * generic/tclFileName.c: removed redundant code.
        * generic/tclIOUtil.c: removed TclStat, TclAccess, TclpListVolumes.
        Fix to MatchInDirectory at the root of a volume.  Also improved
        some documentation, and improved default path joining behaviour
        for virtual filesystems, especially regarding '~'.
        * tests/fileName.test: added tests to check for bugs fixed above.
        * doc/FileName.3: improved documentation

        * generic/tclAsync.c:
        * generic/tclEvent.c:
        * generic/tclInt.h: Improper cleanup of asyncMutex in tclAsync.c
        repaired.  TclFinalizeSynchronization() was trying to remove a
        registered mutex that was dumped earlier when the TSD it was stored
        in was cleared. This was only surfacing on *nix.  Windows was being
        masked by mutexes not actually being returned to the system!  That
        was repaired in a previous patch.  Needed to add a private
        TclFinalizeAsync() to tclAsync.c and called from Tcl_FinalizeThread().
        Pheww..  Is this done yet?

        * unix/tclUnixInit.c (TclpInitLibraryPath):
        * win/tclWinInit.c (TclpInitLibraryPath):  Corrected 
        inconsistency between  the search path for script libraries and
        the directory name $DISTNAME into which distributions built
        by 'make test' unpack.  [Bug 455642]

2001-08-24  Jeff Hobbs  <jeffh@ActiveState.com>

        * tests/stringComp.test: added string-1.3
        * generic/tclCompCmds.c (TclCompileStringCmd): changed to return
        TCL_OUT_LINE_COMPILE instead of TCL_ERROR when compiling and an
        unknown string method is called.  This is necessary as the string
        command may be never called, or not until 'string' is redefined.

2001-08-23  Andreas Kupries <andreas_kupries@users.sourceforge.net>

        * win/tclWinPipe.c (BuildCommandLine): Fixed tcl Bug
          [432499]. Part of the code used the non-absolute path to the
          executable to determine quoting. This failed if the absolute
          path contained spaces, but the application name itself not. This
          bug caused no trouble on Win NT 5, but does for other variants
          in the Win* family. Report and fix due to Ken Poole
          <kenpoole@users.sourceforge.net>.

        Variety of small filesystem and vfs issues fixed or improved.
        The new fs code allows many new opportunities for efficiency
        improvements through the objectified API. The main changes
        integrated here are such efficiency improvements.  Some
        limitations of the original implementation have also now been
        lifted.  Meanwhile a variety of fs bugs (some old, some new)
        have also been fixed.
        
        * generic/tclFileName.c: Made Tcl_FSSplitPath more efficient, 
        and removed some static string-based procedures which are no 
        longer used.  Much more objectification.  Tcl_FSJoinPath
        is now very efficient and more aware of virtual filesystems.
        Clarified where the Mac-specific code attempts to interpret
        Unix-style paths.  Modified TclDoGlob to use lstat not
        access to fix [Bug: 434876, L. Virden]
        * tcl(Win|Unix|Mac)FCmd.c:
        * tcl(Win|Unix|Mac)File.c: replaced TclpListVolumes with
        TclpObjListVolumes with different signature, updated code due
        to more efficient signature of Tcl_FSGetTranslatedPath.  Used
        cached native paths where possible to improve efficiency --
        this was completed on MacOS, but on Unix and Win the traversal
        functions make the task much more complex, so there are still
        some improvements possible there.  Removed unused 
        TclpNormalizePath which had been left in tclWinFCmd.c.
        Objectified all 'file attributes' functions.  Fixed the new
        [Bug:451571, Bruce Stephens] which is most obvious on Unix, 
        but could occur on MacOS or Windows.  This bug actually existed
        in Tcl 8.3.x but was only made obvious by the recent filesystem
        overhaul when the code was exercised more heavily.  
        * tests/fileName.test: Three new tests to exercise the above bug,
        and make sure it is fixed correctly.
        * unix/tclUnixFile.c: avoid panic in glob when a link
        doesn't point anywhere.  It would probably be good to define
        exactly what Tcl should do in circumstances like these, and
        make sure mac/win/unix all behave accordingly. [Bug: 417111, 
        Hemang Lavana]. Also fixed misleading/obsolete comment in the code.
        * generic/tcl.stubs: changed signature of Tcl_FSGetTranslatedPath
        and added Tcl_FSGetTranslatedStringPath.
        These changes allow further optimisations in the FS code.
        * generic/tcl.h: changed signature of Tcl_FSListVolumes so that 
        it doesn't require a Tcl interpreter plus result.  Renamed 
        Tcl_FSReadLink to Tcl_FSLink with additional argument so
        we can support making links in the future. [Patch: 450340]
        * generic/tclInt.h:
        added declaration for TclpObjListVolumes.  Objectified 
        internal call signatures for 'file attributes' functions, and
        added an internal objectified get path type function.
        * generic/tclIOUtil.c: added the moved function TclpListVolumes 
        which calls platform specific code (needed for backwards 
        compatibility), and improved efficiency of parts of the FS
        (particularly file normalization).  Much less copying and
        memory allocation is required now.  added new GetPathType 
        so that changes in 'file volumes' can actually affect files'
        types, and objectified more code.  Made current code work
        with test suite artificially changing current platform.
        Added 'static' keywords where required.
        * generic/tclIO.c:
        * generic/tclTest.c: Added 'static' keywords, fixing 
        [Bug: 453872, Bob Techentin]
        * generic/tclCmdAH.c: file command implementation updated for 
        API changes, removed unnecessary special-case SplitPath static
        function, since it no longer helps prevent code duplication.
        Moved setting of interpreter result to each individual location
        that actually required it, to avoid very large code separation
        between reading and setting the result.
        * doc/FileSystem.3: updated documentation for the new or 
        changed APIs, and clarified some issues.
        * doc/SplitPath.3: added pointer to newer APIs in FileSystem.3
        * doc/filename.n: clarified current implementation of tilde
        support on Mac/Win.  [Bug:453514, Sergey Kuzmin]
        * doc/glob.n: improved documentation for '-directory' and '-path' 
        options.
        
        There are now many private, obsolete, platform-specific 'Tclp' 
        string-based filesystem APIs which could be removed.  We should
        check whether any of these are used by extensions and, at least
        in Tcl 9, remove them.
        
        The above changes signify a ***POTENTIAL INCOMPATIBILITY*** 
        with 8.4a3, since signatures of two functions in the new API 
        have changed, but not with older versions of Tcl.

        * generic/tclBinary.c (FormatNumber): Extract a long from the
        object and not an int, to stop [binary format] from being unable
        to format some input numbers on architectures where sizeof(int) is
        less than sizeof(long) (particularly Alpha.)  [tiprender Bug #441861]

        * tests/format.test: Converted conditional execution of tests into
        a test constraint.

2001-08-22  Jeff Hobbs  <jeffh@ActiveState.com>

        * win/Makefile.in:
        * win/makefile.vc: updated install target for dde1.2
        * doc/dde.n: fixed dde man page (which was totally incorrect).
        * tests/winDde.test:
        * win/tclWinDde.c (Tcl_DdeObjCmd): added -binary option to dde
        request command to allow for returning binary data. [Bug #227482]
        Updated dde to 1.2

        * tests/tcltest.test: added unixExecs constraint to files that
        used 'grep' in the test. [Bug #453143]

        * library/tcltest/tcltest.tcl: fixed stdio constraint test.
        [Patch #454050] (stanton)
        Simplified unixExecs constraint test. 
        
2001-08-22  Don Porter <dgp@users.sourceforge.net>

        * tests/ioUtil.test (ioUtil-3.*): Corrected errors in tests
        revealed by fix of overagressive compiler.  [Bug 451200]

2001-08-21  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclCompCmds.c:
        * tests/compile.test: Fixed overagressive compilation of [catch]:
        it was catching errors at substitution time. [Bug #219184]
        
2001-08-21  Jeff Hobbs  <jeffh@ActiveState.com>

        * tests/tcltest.test (tcltest-12.2): fixed test that would break
        when env vars weren't Tcl list friendly [Patch #454046] (stanton)

2001-08-20  Jeff Hobbs  <jeffh@ActiveState.com>

        * library/http/http.tcl (geturl): added port number to Host:
        header to comply with HTTP/1.1 spec (RFC 2068).  [Bug #452217]

2001-08-16  David Gravereaux <davygrvy@pobox.com>

        * tools/tcl.wse.in:
        * tools/tcl.hpj.in:
        * win/tcl.hpj.in:  Removed -kb storage in CVS to ensure these text
        files are checked-out in the translation mode CVS is in.  Setting
        these as binary as part of an effort to make sure they are always
        in CRLF, no matter what the CVS translation, is bypassing how CVS
        works and is confusing.

        * tools/genStubs.tcl:  Removed LF-only output.  Having to reconvert
        back to CRLF before committing to CVS was giving me a headache.
        [Bug: 451333]

        * win/makefile.vc: replaced $(WINDIR) with $(include32) for the
        .rc.res inference rule.  winver.h wasn't getting included.
        [Bug: 445630]

2001-08-14  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclBasic.c: make the intial maxNestingDepth of an
        interpreter be MAX_NESTING_DEPTH instead of a hardwired value
        [Bug: 232564]

2001-08-13  Miguel Sofer  <msofer@users.sourceforge.net>

        * tests/trace.test: Corrected test numbers [Bug: 449794] 

2001-08-12  Mo DeJong  <mdejong@redhat.com>

        * unix/configure: Regen.
        * unix/configure.in:
        * unix/tcl.m4: Use GCC variable set by AC_PROG_CC instead
        of defining our own using_gcc variable.

2001-08-11  Vince Darley <vincentdarley@users.sourceforge.net>

        Variety of small issues introduced by the vfs code fixed:
        * generic/tclIOUtil.c: uninitialised read.
        * generic/tclFCmd.c: possible memory leak in file delete 
        with error condition.

2001-08-10  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclVar.c: 
        * tests/trace.test: Insure that [array] traces work correctly for
        undefined variables [Bug: 449094] 

2001-08-09  Mo DeJong  <mdejong@redhat.com>

        * unix/Makefile.in: Delete the unused getcwd.o
        target. This fixes bug #440942.

2001-08-08  Don Porter <dgp@users.sourceforge.net>

        * library/dde/pkgIndex.tcl:
        * library/http/http.tcl:
        * library/http/pkgIndex.tcl:
        * library/msgcat/msgcat.tcl:

        * library/reg/pkgIndex.tcl:
        * library/tcltest/tcltest.tcl:
        * library/tcltest/pkgIndex.tcl: Added checks for package dependencies.
        Bumped patchlevels of changed packages:  http 2.3.2, msgcat 1.2.2,
        opt 0.4.3, tcltest 2.0.1.  [Patch 448931]

        * README:

        * unix/configure:
        * unix/configure.in:
        * unix/tcl.spec:
        * win/README.binary:
        * win/configure:
        * win/configure.in: Bumped up patchlevel to 8.4a4 to distinguish
        CVS snapshots from the 8.4a3 release.  This does not necessarily
        mean there will be an 8.4a4 release.  [Bug 448938].

2001-08-06  Jeff Hobbs  <jeffh@ActiveState.com>

        8.4a3 RELEASE

        * changes:
        * README:
        * mac/README: 
        * unix/README:
        * win/README.binary: updated for 8.4a3 release

        * generic/tclFileName.c (Tcl_FSSplitPath): update to Tcl style
        guide.

        * generic/tclFCmd.c (FileCopyRename): fixed mem leak in
        introduction of vfs code where a new Tcl_Obj wasn't freed.

        * generic/tclCmdMZ.c (Tcl_RegexpObjCmd, Tcl_RegsubObjCmd):
        reordered the retrieval of arguments to avoid shimmering bug when
        the pattern and string referenced the same object.

        * unix/configure: regenerated
        * unix/tcl.m4: added GNU (HURD) configuration target. (brinkmann)
        [Patch: #442974]

        * win/README: made note of URL for Windows compilation notes

        * win/tclWinThrd.c (TclpFinalizeMutex, TclpFinalizeCondition):
        added DeleteCriticalSection calls for cleanup [Patch: #419683]

        * unix/tclUnixPipe.c (TclpCreateTempFile): fixed use of tmpnam,
        which is dangerous. [Patch: #442636] (lim)
        The use of tmpnam in TclpTempFileName must still be changed.

        * tests/http.test (http-4.14): fixed variable error return.
        [Bug: 424252]

2001-08-03  Jeff Hobbs  <jeffh@ActiveState.com>

        * win/configure: regenerated
        * win/tcl.m4: fixed DLLSUFFIX definition to always be ${DBGX}.dll.
        This is necessary for TEA compliant builds that build shared
        against a static-built Tcl.
        * win/Makefile.in ($(TCLSH)): added $(TCL_STUB_LIB_FILE) to build
        target, otherwise it wouldn't get generated in a static build.

2001-08-06  Andreas Kupries <andreas_kupries@users.sourceforge.net>

        * generic/tclIOCmd.c (Tcl_GetsObjCmd): Applied patch from SF item
          [442665] to fix the bug reported by it. The function can corrupt
          a freed object if it is called with objc == 3. This is because
          it retrieves resultPtr and does not increment its reference
          count, but then calls Tcl_ObjSetVar2, which causes the retrieved
          resultPtr object to be released.
        
2001-08-06  Don Porter <dgp@users.sourceforge.net>

        * doc/tclsh.1:  Added note that the tclsh program is frequently
        installed with the Tcl version numer as part of the name.
        [Patch 402725]

        * generic/tclPkg.c:
        * tests/pkg.test:  [package forget] now forgets all of the
        package arguments it receives, not stopping when a package is
        not found.  [Bug 415273]

2001-08-02  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclIOUtil.c (Tcl_FSMatchInDirectory): corrected
        uninitialized value.

2001-08-02  Mo DeJong  <mdejong@redhat.com>

        * generic/tclPlatDecls.h:
        * win/tclWinPort.h:
        Revert <tchar.h> related changes made to improve
        Cygwin support on 2001-07-18. This change ended
        up breaking the VC++ build because of conflicts
        between Windows APIs and internal Tk APIs.

2001-08-01  Jeff Hobbs  <jeffh@ActiveState.com>

        * unix/tclUnixFCmd.c: minor casts to eliminate warnings. (lim)
        [Patch: #440218]

        * tests/parseOld.test: changed some tests that required
        testwordend to exist to skip in a proper tcltest manner.
        [Bug: #442663]

        * library/http/http.tcl (http::mapReply): the regsub'ing of \n and
        \t to escape them was unnecessary.

2001-07-24  Mo DeJong  <mdejong@redhat.com>

        * win/tclWinThrd.c (Tcl_CreateThread): Close Windows
        HANDLE returned by _beginthreadex. The MS documentation
        states that this handle is not closed by a later call to
        _endthreadex.

2001-07-21  Don Porter  <dgp@users.sourceforge.net>

        * doc/pkgMkindex.n:
        * library/package.tcl:  Corrected documentation and usage
        message of [pkg_mkIndex].

2001-07-18  Mo DeJong  <mdejong@redhat.com>

        * generic/tclPlatDecls.h: Define TCHAR by including
        windows.h instead of tchar.h since Cygwin does not
        support the tchar.h header. Include CHECK_UNICODE_CALLS
        logic from tclWinPort.h.
        * win/tclWinPort.h: Remove CHECK_UNICODE_CALLS logic.
        Remove include of windows.h since this now done it
        tclPlatDecls.h.
        * win/tclWinReg.c: Remove duplicate include of windows.h.

2001-07-18  Andreas Kupries <andreas_kupries@users.sourceforge.net>

        * generic/tclIO.c: Aftermath to [SF #427196]. Squash empty buffers
          if they are smaller than the requested buffersize, to prevent
          reusage of old buffers and to honor changes in the requested
          buffersize made by the user.

2001-07-17  Mo DeJong  <mdejong@redhat.com>

        * win/tclWinFile.c (TclpReadlink): Add Cygwin specific definition
        for the TclpReadlink function. This method implements reading of
        symbolic links when build with Cygwin.

2001-07-17  Mo DeJong  <mdejong@redhat.com>

        * win/tclWinPort.h: Add Cygwin specific defines for environ
        and timezone variables.

2001-07-17  Andreas Kupries <andreas_kupries@users.sourceforge.net>

        * generic/tclIO.c (GetInput): Fixed [SF #427196]. Memory was
          overwritten because a buffer was used after a change of the
          requested buffersize together with that requested buffersize and
          not its actual size, which was smaller. Note that the continous
          reuse of the smaller buffer negatively impacts performance. The
          system never allocates a buffer with the newly requested bigger
          buffersize.

2001-07-16  Mo DeJong  <mdejong@redhat.com>

        * generic/tcl.h: Define __WIN32__ when
        __CYGWIN__ or __MINGW32__ is defined.
        * generic/tclAlloc.c: Define caddr_t when
        compiling with VC++ or mingw. This type is
        already defined when compiling with Cygwin.

2001-07-16  Mo DeJong  <mdejong@redhat.com>

        * win/tclWinConsole.c:
        * win/tclWinPipe.c:
        * win/tclWinPort.h:
        * win/tclWinSerial.c:
        * win/tclWinThrd.c:
        Remove unnecessary #includes of dos.h, direct.h,
        and tchar.h. This will help the Cygwin porting
        effort since these headers do not exist under Cygwin.

2001-07-16  Jeff Hobbs  <jeffh@ActiveState.com>

        * win/tclWinPipe.c (PipeClose2Proc): constrained the mutex lock to
        just the TerminateThread call and waiting for termination. (jsmith)

        * generic/tclCmdMZ.c: Removed extra copy of the SCAN_* macros
        #defined in generic/tclScan.c. (porter) [Bug 441230]

2001-07-12  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/unixInit.test (unixInit-2.8): Added extra constraint,
        notInstalledInTmp, to stop this test from damaging installations
        in /tmp; not much fun to have to reinstall the Tcl library every
        time you run the test suite!

        * tests/subst.test (subst-10.*): Updated tests to check new
        behaviour for 'break' in command substitutions.
        (subst-1.2,subst-7.1): Error messages changed.
        * doc/SubstObj.3: New file, to document Tcl_SubstObj.
        * doc/subst.n: Improved and updated documentation for 'subst' to
        help support the changed behaviour.
        * generic/tcl.decls (generic-437): Declaration for Tcl_SubstObj
        * generic/tcl.h (TCL_SUBST_*): Added flags for Tcl_SubstObj.
        * generic/tclCmdMZ.c (Tcl_SubstObj,Tcl_SubstObjCmd): Divided into
        two parts to allow people to access the innards of 'subst' and
        changed the behaviour when command substitutions do a 'break' to
        be different from 'continue'.  Also now works with objects, which
        allows for some nifty optimisations with variable substitutions
        and a slight improvement with command substitutions.  [TIP#36]

2001-07-10  Mo DeJong  <mdejong@redhat.com>

        * unix/Makefile.in: Add AR variable for use in STLIB_LD.
        * unix/configure: Regen.
        * unix/configure.in: Use STLIB_LD when defining MAKE_LIB
        and MAKE_STUB_LIB. Subst RANLIB and AR.
        * unix/tcl.m4 (SC_CONFIG_CFLAGS): Add doc comment about
        STLIB_LD command. Check ${AR} env var when setting
        STLIB_LD and delay evaluation until make time.
        * win/configure: Regen.
        * win/tcl.m4 (SC_CONFIG_CFLAGS): Delay evaluation of
        ${AR} in STLIB_LD and add flags to better match the
        Unix implementation. Don't bother defining AR when
        using VC++ since it is not used.

2001-07-06  Mo DeJong  <mdejong@redhat.com>

        * win/configure: Regen.
        * win/tcl.m4 (SC_CONFIG_CFLAGS): Pass -e _WinMain@16 in
        addition to the -mwindows flag to work around a problem
        with ld when it incorrectly use main() as the executable
        entry point when both WinMain() and main() are available.

2001-07-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/cmdAH.test: Added leading zero to file modes to work
        around fault in HPUX strtol() which ignores the base parameter
        [Bug #438808]

2001-07-05  Mo DeJong  <mdejong@redhat.com>

        * win/Makefile.in: Subst DEPARG directly instead
        of relying on a variable. This will make Cygwin
        builds faster since an extra exec will be avoided.
        * win/configure: Regen.
        * win/configure.in: Subst DEPARG.
        * win/tcl.m4 (SC_CONFIG_CFLAGS): Move AC_MSG_CHECKING
        after the AC_CHECK_PROG so that status messages do
        not get mixed together. Set DEPARG based on the
        results of the cygpath check so that we avoid using
        an extra exec when it is not needed. Use ac_cv_cygwin
        status flag instead of looking at the output of
        gcc -v, which works in the case where -mno-cygwin is
        set in the CFLAGS.

2001-07-04  Jeff Hobbs  <jeffh@ActiveState.com>

        * README:
        * mac/README:
        * unix/README:
        * win/README:
        * win/README.binary: updated READMEs with purls

2001-07-03  Mo DeJong  <mdejong@redhat.com>

        * win/Makefile.in: Remove PATHTYPE variable.
        * win/configure: Regen.
        * win/configure.in: Don't subst PATHTYPE.
        * win/tcl.m4 (SC_CONFIG_CFLAGS): Remove PATHTYPE
        variable. Set CYGPATH to "cygpath -w" if the
        cygpath executable is found on the path. This
        approach works for native Cygwin builds and
        cross compiles.

2001-07-03  Jeff Hobbs  <jeffh@ActiveState.com>

        * tests/var.test:
        * generic/tclVar.c (Tcl_VariableObjCmd): added patch to check for
        number of args. [Patch #426038]

        * generic/tclVar.c (Tcl_GetVar2Ex): added ability to recognize
        TCL_TRACE_READS flags to cause creation of part1 in TclLookupVar
        to make sure newly created array will get read traces triggered
        appropriately.  This is called by Tcl_ObjGetVar2, Tcl_GetVar, and
        Tcl_GetVar2.
        (TclSetIndexedScalar, TclSetElementOfIndexedArray): added read
        trace triggering for lappend case.
        (Tcl_LappendObjCmd): pass TCL_TRACE_READS to Tcl_ObjGetVar2 to
        trigger possible read traces for new arrays.

        * generic/tclExecute.c (TclExecuteByteCode): added TCL_TRACE_READS
        flag to INST_LAPPEND(_ARRAY)_STK case to trigger read traces for
        newly created arrays.  Removed unnecessary #ifdef for
        TCL_COMPILE_DEBUG in INST_LOAD_SCALAR1 case.

        * tests/append.test:
        * tests/appendComp.test: added tests for read trace triggering for
        append and lappend.

2001-07-03  Mo DeJong  <mdejong@redhat.com>

        * tests/clock.test (clock-2.5): Adjust test so that it passes
        when the time slice is 60 msecs, now passes under Windows 98.

2001-07-03  Mo DeJong  <mdejong@redhat.com>

        * win/tcl.m4 (SC_CONFIG_CFLAGS): Don't pass the v flag
        to ${AR} when using gcc, verbose output is not needed.

2001-07-03  Don Porter  <dgp@users.sourceforge.net>

        * tests/unixInit.test (unixInit-2.8):  Changed test back to using
        installation layout, adding comments explaining why the test writes
        to the directories it does, and checks to avoid destroying other
        files in /tmp.

2001-07-03  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/unixInit.test (unixInit-1.2): Fixed faults reported in
        Bug#438070 - well, at least enough to work on Solaris - and added
        comments that should make what is going on in the test clearer.

2001-07-02  Jeff Hobbs  <jeffh@ActiveState.com>

        * tests/util.test: added util-4.6
        * generic/tclUtil.c (Tcl_ConcatObj): Corrected walking backwards
        over utf-8 chars. [Bug #227512]

2001-07-02  Don Porter  <dgp@users.sourceforge.net>

        * tests/unixInit.test (unixInit-2.8):  Corrected test for all
        absolute pathnames in library path when executable is installed
        near root directory to use correct development directory layout.
        [Bug 438014]

        * tests/unixInit.test (unixInit-2.9):  
        * unix/tclUnixInit.c (TclpInitLibraryPath):
        * win/tclWinInit.c (TclpInitLibraryPath):  Corrected buggy
        construction of search path entries relative to executable.
        Added test for bad construction.  [Bug 438014]

2001-06-28  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclNamesp.c: Correction to faulty patch from [Bug: 231259] 

2001-06-28  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/unixInit.test (unixInit-1.2): Modified so as not to
        require a local echo service, which fails on many systems which
        have that turned off for security reasons...

2001-06-27  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclInt.h:
        * generic/tclObj.c:
        * unix/Makefile.in: added a -DPURIFY mode that makes Tcl_Obj's
        allocated and free singularly (instead of in alloc in blocks and
        never free) to allow checkers like Purify to operate better.

        * library/encoding/koi8-u.enc: added koi8-u (Ukranian variant)
        encoding.

        * tests/subst.test:
        * generic/tclUtf.c (Tcl_UtfBackslash): Corrected backslash
        handling of multibyte utf-8 chars. [Bug #217987]

        * generic/tclCmdIL.c (InfoProcsCmd): fixed potential mem leak in
        info procs that created objects without using them.

        * generic/tclCompCmds.c (TclCompileStringCmd): fixed mem leak when
        string command failed to parse the subcommand.

        * doc/interp.n:
        * doc/unknown.n: updated notes about what is in a safe interp.
        [Bug #218605]

2001-06-27  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/event.test (event-11.5): Removed hard-coded port number
        which could fail on some systems.  [Bug #436727]

2001-06-26  Mo DeJong  <mdejong@redhat.com>

        * unix/Makefile.in:
        * win/Makefile.in: Add `make shell` target. This target
        will set the proper env vars before invoking tclsh
        from the build directory.

2001-06-26  Mo DeJong  <mdejong@redhat.com>

        * win/Makefile.in: Use : to separate VPATH entries. This
        works for both Cygwin builds and cross builds, the VPSEP
        variable is simply unneeded complexity.
        * win/configure: Regen.
        * win/configure.in: Don't subst VPSEP.
        * win/tcl.m4 (SC_CONFIG_CFLAGS): Remove VPSEP variable.

2001-06-26  Mo DeJong  <mdejong@redhat.com>

        * unix/configure: Regen.
        * unix/configure.in: Fix last checkin by removing
        export since that only works in bash.
        * win/configure: Regen.
        * win/configure.in: Ditto.

2001-06-26  Mo DeJong  <mdejong@redhat.com>

        * unix/configure: Regen.
        * unix/configure.in: Set CFLAGS to "" if the user
        did not set CFLAGS in the env. This keeps AC_PROG_CC
        from adding "-g -O2" to the CFLAGS by default.
        * win/configure: Regen.
        * win/configure.in: Ditto.

2001-06-25  Mo DeJong  <mdejong@redhat.com>

        * win/configure: Regen.
        * win/configure.in: Use RC_DEFINE flag from tcl.m4.
        * win/tcl.m4 (SC_CONFIG_CFLAGS): Set RC_DEFINE
        flag based on the compiler in use.
        
2001-06-25  Mo DeJong  <mdejong@redhat.com>

        * win/tcl.m4 (SC_CONFIG_CFLAGS): Link to the
        imm32 library when building with mingw gcc.

2001-06-25  Mo DeJong  <mdejong@redhat.com>

        * win/configure: Regen.
        * win/tcl.m4 (SC_CONFIG_CFLAGS): When building with
        gcc, don't attempt to link with LD or support dllwrap.
        Simply require a recent version of Cygwin gcc or Mingw
        gcc that supports -shared. When linking, use gcc instead
        of ld since gcc automatically includes libs like -lmsvcrt.

2001-06-22  Mo DeJong  <mdejong@redhat.com>

        * win/configure: Regen.
        * win/configure.in: Add resource compiler fix from
        8.3.3 to fix compiling with mingw.

2001-06-22  Mo DeJong  <mdejong@redhat.com>

        * win/configure: Regen.
        * win/tcl.m4: Fix silly typo in last checkin.

2001-06-22  Mo DeJong  <mdejong@redhat.com>

        * unix/Makefile.in: Set CFLAGS to @CFLAGS@ and @CFLAGS_DEFAULT@.
        Set LDFLAGS to @LDFLAGS@ and @LDFLAGS_DEFAULT@. Add LDFLAGS_DEBUG
        and LDFLAGS_OPTIMIZE to match the way CFLAGS_DEFAULT works.
        This will support user set CFLAGS or LDFLAGS at configure time.
        * unix/configure: Regen.
        * unix/configure.in: Don't set CFLAGS to CFLAGS_DEFAULT, instead
        subst CFLAGS_DEFAULT into the Makefile. Add AC_SUBST for CFLAGS_DEFAULT,
        LDFLAGS_DEFAULT, LDFLAGS_DEBUG, and LDFLAGS_OPTIMIZE.
        * unix/tcl.m4 (SC_ENABLE_SYMBOLS): Modify LDFLAGS_DEFAULT so that
        it uses a Makefile variable just like CFLAGS_DEFAULT.
        * win/Makefile.in: Set CFLAGS to @CFLAGS@ and @CFLAGS_DEFAULT@.
        Set LDFLAGS to @LDFLAGS@ and @LDFLAGS_DEFAULT@.
        This will support user set CFLAGS or LDFLAGS at configure time.
        * win/configure: Regen.
        * win/configure.in: Don't set CFLAGS or LDFLAGS, instead subst
        CFLAGS_DEFAULT and LDFLAGS_DEFAULT into the Makefile.
        * win/tcl.m4 (SC_ENABLE_SYMBOLS): Modify LDFLAGS_DEFAULT so that
        it uses a Makefile variable just like CFLAGS_DEFAULT.

2001-06-22  Mo DeJong  <mdejong@redhat.com>

        * win/configure:
        * win/tcl.m4 (SC_CONFIG_CFLAGS): Don't set LDFLAGS_DEBUG
        to -g or LDFLAGS_OPTIMIZE to -O when compiling with gcc.
        These flags are not needed and can cause problems with
        the Cygwin version of ld.

2001-06-18  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/unixInit.test (unixInit-1.2,unixInit-2.8): Added test for
        code described below, and fixed a couple of errors that caused
        problems during testing; the code to determine the installedTcl
        constraint was wrong, and test unixInit-2.8 assumed that /tmp/lib
        was free for use and could be deleted, which clashed nastily with
        my installation and made other tests fail unnecessarily!

        * unix/tclUnixChan.c (TtyInit,TclpOpenFileChannel,
        Tcl_MakeFileChannel,TclpGetDefaultStdChannel): Alterations so that
        the standard channels - stdin, stdout and stderr - have the
        correct type and fconfigure options.  This required making the
        initialisation of serial lines a little more sophisticated to
        make the console behave correctly in interactive mode... [Bug
        #219137 and duplicates]

2001-06-16  Don Porter  <dgp@users.sourceforge.net>

        * mac/tclMacPanic.c (TclpPanic):
        * unix/tclUnixPort.h:
        * win/tclWinPort.h: Replaced TclMacSetPanic with TclpPanic
        for setting a platform-specific panic handler.  TclpPanic
        is NULL on Unix and Windows.  Fixes broken wish on Mac due
        to earlier patches.  [Patch 415648]
        
        * generic/tclIntPlatDecls.h:
        * generic/tclStubInit.c: `make gentubs` after above changes.

        * mac/tclMacAppInit.c (main, Macintosh_Init):
        * mac/tclMacBOAAppInit.c (main):

        problems on the Macintosh in the 2001-06-08 changes.

2001-06-12  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/regexp.test (regexp-18.12): 
        * generic/tclCmdMZ.c (Tcl_RegexpObjCmd): Fixed so that submatches
        that do not match always have index pair {-1 -1} [Bug #219232]

2001-06-08  Don Porter  <dgp@users.sourceforge.net>

        * generic/tcl.h:
        * generic/tcl.decls:
        * generic/tclPanic.c: Added CONST to Tcl_*Panic* public interfaces.
        [Patch 415648, TIP 27]

        * generic/tclInt.decls:
        * mac/tclMacAppInit.c (main):
        * mac/tclMacBOAAppInit.c (main):
        * mac/tclMacPanic.c: Modified special Mac implementations of
        Tcl_*Panic* to be exact copies of the generic implementations.
        Added TclMacSetPanic.  The generic implementations should be
        used directly, rather than copies, but that requires further
        changes by someone familiar with the Mac build systems.
        [Patch 415648]

        * generic/tclDecls.h:
        * generic/tclIntPlatDecls.h:
        * generic/tclStubInit.c: `make gentubs` after above changes.

        * doc/Panic.3:
        * unix/mkLinks:  New file documenting Tcl_*Panic* public interfaces,
        followed by `make mklinks`.  [Patch 415648, Bug 219170, Bug 414936]

2001-06-03  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclUtil.c (Tcl_DStringAppendElement): patch to save an
        extra strlen call.  [Bug #428572]

2001-05-30  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * generic/tclExecute.c (TclExecuteByteCode): Added two casts to
        INST_STR_CMP implementation to get rid of a couple warnings from
        the SUNWspro C compiler.

        * generic/tclBasic.c (Tcl_GetMathFuncInfo,Tcl_ListMathFuncs): 
        * generic/tclCmdIL.c (Tcl_InfoObjCmd,InfoFunctionsCmd): 
        * generic/tcl.decls (generic table, positions 435+436): 
        * tests/info.test: 
        * doc/CrtMathFnc.3: 
        * doc/info.n: Changes due to TIP #15 "Functions to List and Detail
        Math Functions"

2001-05-28  Jeff Hobbs  <jeffh@ActiveState.com>

        * library/init.tcl (unknown): removed errant " in error message

2001-05-27  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/regc_locale.c: updated character class range data for
        Unicode v3.1.0 compliance.
        * generic/tclUniData.c: regenerated from Unicode v3.1.0 data file
        (new as of 2001-05-16).  This brings Tcl to current unicode
        compliance.

        * tests/utf.test: added tests to check unicode 3 compliance

        * unix/Makefile.in (tclUtf.o): added tclUniData.c dependency.

        * tools/uniClass.tcl: added comments to output format and the
        script for clarification.

        * tools/uniParse.tcl: corrected filename output and GetDelta macro
        to use 'info' as param (was 'infO')

2001-05-26  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * generic/tclVar.c (tclArraySearchType,SetArraySearchObj,
        ParseSearchId): Added code to speed up array searching by reducing
        the amount of parsing needed for searchIds.

        * generic/tclObj.c (TclInitObjSubsystem): 
        * generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct): 
        * generic/tclNamesp.c (TclInitNamespaceSubsystem): 
        * generic/tclInt.h: Moved some Tcl_ObjType initialisation to
        TclInitObjSubsystem to be with the bulk of the rest.

2001-05-23  Jeff Hobbs  <jeffh@ActiveState.com>

        * tests/io.test: changed io-52.[9-11] to not be platform sensitive

2001-05-23  Mo DeJong  <mdejong@redhat.com>

        * unix/tcl.m4 (SC_PATH_TCLCONFIG): Fix comments,
        and typo in cached variable name.

2001-05-23  Mo DeJong  <mdejong@redhat.com>

        * unix/tcl.m4 (SC_LOAD_TKCONFIG):
        Remove use of undefined TCLCONFIG variable and
        call AC_MSG_RESULT to print the checking result.
        * win/tcl.m4: Ditto.

2001-05-22  Jeff Hobbs  <jeffh@ActiveState.com>

        * generic/tclObj.c (TclAllocateFreeObjects): simplified
        objSizePlusPadding to use sizeof(Tcl_Obj) (max)
        Corrected use of tclObjsAlloced/Freed/Shared in TCL_MEM_DEBUG
        compile.

2001-05-22  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclExecute.c: removed Tcl_DuplicateObj in INST_DUP 

2001-05-21  Jeff Hobbs  <jeffh@ActiveState.com>

        * tests/tcltest.test (tcltest-19.1): fixed failing test that was
        getting affected by Windows env handling of empty valued elements.

        * unix/tcl.m4: added more common install directories in which to
        search for *Config.sh [Bug #419812]

        * tests/cmdMZ.test (cmdMZ-1.4): added notLinux constraint to test
        to prevent failure message on Linux due to OS caching bug.

        * tests/httpd (httpdRespond): added response to timeout value in
        query string.

        * tests/http.test: removed unused notLinux constraint setting

        * generic/tclRegexp.c (Tcl_RegExpExecObj): added use of
        Tcl_GetUnicodeFromObj.

2001-05-19  Andreas Kupries <andreas_kupries@users.sourceforge.net>

        * Note that "tclbench" (see project "tcllib") was extended with
          performance benchmarks for [fcopy] too.

        * doc/fcopy.n: Updated to reflect the extended behaviour of 'fcopy'.

        * tests/io.test: Added tests 'io-52.9', 'io-52.10' and 'io-52.11'
          to test the handling of encodings by 'fcopy' / 'TclCopychannel'
          [Bug #209210].

        * generic/tclIO.c: Split of both 'Tcl_ReadChars' and
          'Tcl_WriteChars' into a public error checking and an internal
          working part. The public functions now use the new internal
          ones. The new functions are 'DoReadChars' and 'DoWriteChars'.
          Extended 'CopyData' to use the new functions 'DoXChars' when
          required by the encodings on the input and output channels
          [Bug #209210].

2001-05-16  Jeff Hobbs  <jeffh@ActiveState.com>

        * library/history.tcl (tcl::HistAdd): prevent empty calls from
        being added to the history (arndt)

        * tests/error.test: updated error-1.3 message to account for
        string index being compiled at toplevel.
        * tests/appendComp.test:
        * tests/stringComp.test: new files for extended bytecode testing

        * generic/tclBasic.c: added new CompileProc invocations to basic
        command initialization.
        * generic/tclCompCmds.c: added new compile commands for append,
        lappend, lindex and llength.  Refactored set and incr compile
        commands to use new TclPushVarName function for handling the
        varname component during compilation (also used by append and
        lappend).  Changed string compile command to compile toplevel code
        as well (when possible).
        * generic/tclCompile.c: added new instruction enums
        * generic/tclCompile.h: added debug info for new instructions
        * generic/tclExecute.c (TclExecuteByteCode): moved elemPtr to
        toplevel var (oft-used).  Added definitions for new bytecode
        instructions INST_LIST_INDEX, INST_LIST_LENGTH, INST_APPEND_SCALAR1,
        INST_APPEND_SCALAR4, INST_APPEND_ARRAY1, INST_APPEND_ARRAY4,
        INST_APPEND_ARRAY_STK, INST_APPEND_STK, INST_LAPPEND_SCALAR1,
        INST_LAPPEND_SCALAR4, INST_LAPPEND_ARRAY1, INST_LAPPEND_ARRAY4,
        INST_LAPPEND_ARRAY_STK, INST_LAPPEND_STK.
        Refactored repititious code for reuse with INST_LOAD_STK (same as
        INST_LOAD_SCALAR_STK), INST_STORE_STK (same as
        INST_STORE_SCALAR_STK).
        Updated INST_STR_CMP with style of fix of 2001-04-06 Fellows
        [Bug #219201] as that fix only affected the runtime eval'ed
        "string" (string compare is normally byte-compiled now).  We
        may want to back these out for speed in the future, noting the
        problems with \x00 comparisons in the docs.
        * generic/tclInt.h: declarations for new compile commands.
        * generic/tclVar.c: change TclGetIndexedScalar,
        TclGetElementOfIndexedArray, TclSetElementOfIndexedArray and
        TclSetIndexedScalar to use flags.  The Set functions now support
        TCL_APPEND_ELEMENT and TCL_LIST_ELEMENT as well.
        * generic/tclInt.decls:
        * generic/tclIntDecls.h: minor signature changes for above.

        * generic/tclCmdMZ.c: made use of new Tcl_GetUnicodeFromObj.

        * unix/tclUnixPipe.c: updated pipeChannelType to
        TCL_CHANNEL_VERSION_2 type specification.

        * tests/fileName.test: corrected tests not to fail on win when a
        C:/test dir exists.

2001-05-15  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * doc/console.n: Created.  It seems very odd to me that the
        console implementation is part of the Tcl distribution and not
        part of Tk, but given the location of the source, the
        documentation must obviously match up...

2001-05-14  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * generic/tclCmdMZ.c (Tcl_StringObjCmd): 
        * tests/string.test (string-4.14): Negative string indices should
        not be added as offsets to the result of [string first] but
        instead be treated as referring to the start of the string.
        [Bug: 423581]

2001-05-11  Mo DeJong  <mdejong@redhat.com>

        * unix/Makefile.in: Add a LDFLAGS variable to the
        Makefile instead of directly substing @LDFLAGS@.
        * unix/configure: Regen.
        * unix/tcl.m4: Fix CFLAGS_DEFAULT so that the name
        of a Makefile variable is passed as @CFLAGS@.
        * win/Makefile.in: Move the setting of CFLAGS
        higher up in the Makefile.
        * win/configure: Regen.

        * tools/tcltk-man2html.tcl: removed use of 'exec' for portability
        and fixed up code.

2001-05-03  Don Porter  <dgp@users.sourceforge.net>

        * doc/library.n:
        * library/init.tcl:
        * tests/autoMkindex.t*: Modified [auto_import] to apply
        pattern matching in the [namespace import] style.  [Bug 420186]
        ***POTENTIAL INCOMPATIBILITY*** for any callers of [auto_import]
        from outside Tcl that expect the pattern matching to be like that
        of [string match].

2001-05-03  Miguel Sofer  <msofer@users.sourceforge.net>

        * generic/tclParse.c: 
        * tests/namespace.test: Insure consistent behaviour of the
        [unknown] command: when a command is unknown, it is always
        processed by [::unknown], ignoring any namespace proc which
        happens to be called "unknown" [Patch #421166, Bug #420507]

2001-05-02  Don Porter  <dgp@users.sourceforge.net>

        * tools/genStubs.tcl: Add a package require of Tcl 8
        at the beginning of the script so that the script
        will print a descriptive error message when run
        in an old Tcl 7 shell.

        * unix/configure: Regen.

        instances of STUB_LIB_FILE with TCL_STUB_LIB_FILE.

        currency symbol) support.

        [Patch #415179]
        ***POTENTIAL INCOMPATIBILITY*** from 8.4a2, in which Vince
        Darley's changes to command tracing were added.  A const has been

2001-04-10  Kevin B. Kenny    <kennykb@acm.org>

        compatibility.
        
2001-04-10  Kevin B. Kenny    <kennykb@acm.org>

        * unix/tclUnixTime.c: Fixed silly typo in calls to 'gmtime' and
        'localtime' that broke the Linux build.

2001-04-09  Kevin B. Kenny    <kennykb@acm.org>

        * unix/tclLoadShl.c: Added DYNAMIC_PATH to the load flags so that

2001-04-09  Kevin B. Kenny    <kennykb@acm.org>

        * tests/expr.test (expr-21.*): Tests to check below fix.
        * generic/tclParseExpr.c (GetLexeme): Now recognises the
        non-numeric boolean literals for what they are. It no longer makes
        sense for anyone to create functions with the same name as one of
        them, but this was true in 7.* as well [Bug #217777; finally!]

2001-04-07  Miguel Sofer <msofer@users.sourceforge.net>

        * tests/string.test (string-2.30): Test for this case
        * generic/tclCmdMZ.c (Tcl_StringObjCmd, STR_COMPARE branch): Fixed
        problem caused by Utf-rep of \x00 being more than Utf-rep of \x01
        fooling memcmp by forcing everything through Utf-based
        comparisons.  Added optimizations for case where objects have a
        string/unicode-rep or a bytearray-rep (i.e. where we can perform
        comparisons on fixed-size units.) [Bug #219201]
        * generic/tclUtf.c (Tcl_UtfNcmp): Corrected seriously erroneous

2001-03-12  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * tests/string.test: Fixed some test numberings and added a test.
        [Patch #403229]

2001-03-06  Donal K. Fellows  <fellowsd@cs.man.ac.uk>

        * generic/tclVar.c (Tcl_UnsetObjCmd): Rewrote argument parser to
        avoid a read off the end of the argument array that could occur
        when executing something like [unset -nocomplain] was executed.
        Improved the error message given when too few arguments are given
        (-nocomplain should obviously be *before* --, not after it) and
        also modified the test suite to take account of that and the
        documentation to use the same improvement. [Bug 405769]

        * generic/tclExecute.c (TclExecuteByteCode): Fixed bug that could
        pass pointers to freed memory to command implementations, which
        most obviously caused some weird behaviour with [info level], but
        could have caused problems with user code and command traces too.

        * no changes; fixing up the missing comment in the previous one.
        Sorry.

        * /cvsroot/tcl/tcl/tests/execute.test:
        added test for evaluation of an expression in a variable; evals once
        by compiling, second time using the previous compilation

2001-02-18  Kevin B. Kenny  <kennykb@acm.org>

        * doc/clock.n: Updated documentation to reflect the addition of
        compat/strftime.c, including the correct formatting of
        ISO-8601:1988 fiscal week number (%V).

        * generic/tclCmdMZ.c (Tcl_SplitObjCmd): Improved efficiency of
        splitting strings into individual characters by adding hash so
        that only one Tcl_Obj per character is created.  Improves
        performance of splitting of short strings and makes a huge
        difference to splitting of long strings, such as is done in the
        mime package in tcllib.  [Bug #131523]

2001-01-31  Don Porter  <dgp@users.sourceforge.net>

        * win/makefile.vc (install-libraries):  Corrected misdirected
        install directory for the msgcat 1.2 package.

2001-01-30  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclIO.c (CopyData): Moved code that updates the count
        of how many bytes are left to copy.  Corrects bug that when
        writing occurs in the background, the copy loop could be
        escaped without updating the count, causing CopyData() to try
        to copy more bytes than the toRead value originally passed to
        TclCopyChannel(), leading to hangs and misreporting of number
        of bytes copied. [Bug 118203, Patch 103432]

        * Everything below belongs together, it fixes bug #123153.

        * generic/tcl.h (line 342): A bit more explanation about the
          default value for TCL_PRESERVE_BINARY_COMPATABILITY.

        * generic/tcl.h (line 1208): Define the macro 'Tcl_InitHashTable'
          only when TCL_PRESERVE_BINARY_COMPATIBILITY is not set
          as it kills binary compatibility to 8.3 and earlier
          versions. This is the main part of the patch/change.

        * generic/tcl.decls (line 1469):
        * generic/tclHash.c (Tcl_InitHashTable):
        * generic/tclHash.c (Tcl_InitHashTableEx):
        * generic/tclObj.c (Tcl_InitObjHashTable): Changed
          'Tcl_InitHashTableEx' to 'Tcl_InitCustomHashTable'. This change
          is more of an estethical nature, replacing the ubiquitous 'Ex'
          suffix with a more meaningful name. The introduced binary
          incompatibility is deemed acceptable as it is between alpha
          versions.  Updated callers.

        * doc/Hash.3:
        * unix/mkLinks: Changed 'Tcl_InitHashTableEx' to
          'Tcl_InitCustomHashTable'.

        * tests/winPipe.test (winpipe-1.20): 
        * tests/winDde.test (createChildProcess): 
        * tests/pkgMkIndex.test (pkgtest::createIndex):  Removed
        assumption that paths contain no spaces which causes problems with
        both [eval] and [open |...] due to the well-known differences
        between lists and strings.  Fixes bug #119406

2001-01-04  Don Porter  <dgp@users.sourceforge.net>

        * tests/unixInit.test:
        * unix/tclUnixInit.c (TclpInitLibraryPath):
        * win/tclWinInit.c (TclpInitLibraryPath):  Several entries in
        the library path ($tcl_libPath) are determined relative to the
        absolute path of the executable.  When the executable is
        installed in or near the root directory of the file system,
        relative pathnames were being incorrectly generated, and in
        the worst case, memory access violations were crashing the program.
