Corrected a bug in cache - management for format strings containing [glob] metacharacters [Bug - 1494664]. Corrected several errors in formatting/scanning of years - prior to the Common Era, and added the missing %EE format group to - indicate the era. - * tools/makeTestCases.tcl: Added code to make sure that %U and %V - format groups are included in the tests. (The code depends on %U and %V - formatting working correctly when 'makeTestCases.tcl' is run, rather - than making a completely independent check.) Added tests for [glob] - metacharacters in strings.

Allows calling exeve() in processes where - the event loop has not yet been run (Darwin's execve() fails in - processes with more than one thread), in particular allows embedders to - call fork() followed by execve(), previously the pthread_atfork() child - handler's call to Tcl_InitNotifier() would immediately recreate the - notifier thread in the child after a fork. - - * macosx/tclMacOSXFCmd.c (TclMacOSXCopyFileAttributes): add support - * macosx/tclMacOSXNotify.c (Tcl_InitNotifier): for weakly - * unix/tclUnixInit.c (Tcl_GetEncodingNameFromEnvironment): importing - symbols not available on OSX 10.2 or 10.3, enables binaires built on - later OSX versions to run on earlier ones. - * macosx/Tcl.xcodeproj/project.pbxproj: enable weak-linking; turn on - extra warnings. - * macosx/README: document how to enable weak-linking; cleanup. - * unix/tclUnixPort.h: add support for weak-linking; conditionalize - AvailabilityMacros.h inclusion; only disable realpath on 10.2 or earlier - when threads are enabled. - * unix/tclLoadDyld.c (TclpLoadMemoryGetBuffer): change runtime Darwin - * unix/tclUnixInit.c (TclpInitPlatform): release check to use - global initialized once. - * unix/tclUnixFCmd.c (DoRenameFile, TclpObjNormalizePath): add runtime - Darwin release check to determine if realpath is threadsafe. - * unix/configure.in: add check on Darwin for compiler support of weak - * unix/tcl.m4: import and for AvailabilityMacros.h header; - move Darwin specific checks & defines that are only relevant to the tcl - build out of tcl.m4; restrict framework option to Darwin; cleanup - quoting and help messages. - * unix/configure: autoconf-2.59 - * unix/tclConfig.h.in: autoheader-2.59 - - * generic/regc_locale.c (cclass): - * generic/tclExecute.c (TclExecuteByteCode): - * generic/tclIOCmd.c (Tcl_ExecObjCmd): - * generic/tclListObj.c (NewListIntRep): - * generic/tclObj.c (Tcl_GetLongFromObj, Tcl_GetWideIntFromObj, - FreeBignum, Tcl_SetBignumObj): - * generic/tclParseExpr.c (Tcl_ParseExpr): - * generic/tclStrToD.c (TclParseNumber): - * generic/tclStringObj.c (TclAppendFormattedObjs): - * unix/tclLoadDyld.c (TclpLoadMemory): - * unix/tclUnixPipe.c (TclpCreateProcess): fix signed-with-unsigned - comparison and other warnings from gcc4 -Wextra. - -2006-07-13 Andreas Kupries <andreask@activestate.com> - - * unix/tclUnixPort.h: Added the inclusion of <AvailabilityMacros.h>. - The missing header caused the upcoming #if conditions to wrongly - exclude realpath, causing file normalize to ignore symbolic links in - the path. - -2006-07-11 Zoran Vasiljevic <vasiljevic@users.sourceforge.net> - - * generic/tclAsync.c: Made Tcl_AsyncDelete() more tolerant when called - after all thread TSD has been garbage-collected. - -2006-07-05 Don Porter <dgp@users.sourceforge.net> - - * generic/tclParseExpr.c: Completely new expression parser that - builds a parse tree instead of operating with deep recursion. This - corrects reports of stack-blowing crashes parsing long expressions [Bug - 906201] and replaces a fundamentally O(N^2) algorithm with an O(N) one - [RFE 903765]. The new parser is better able to generate error messages - that clearly report both the nature and context of the syntax error - [Bugs 1029267, 1381715]. For now, the code for the old parser is still - present and can be activated with a "#define OLD_EXPR_PARSER 1". This - is for the sake of a clean implementation patch, and for ease of - benchmarking. The new parser is non-recursive, so much lighter in stack - consumption, but it does use more heap, so there may be cases where - parsing of long expressions that succeeded with the old parser will - lead to out of memory panics with the new one. There are still more - improvements possible on that point, though significant progress may - require changes to the Tcl_Token specifications documented for the - public Tcl_Parse*() routines. - ***POTENTIAL INCOMPATIBILITY*** for any callers that rely on the exact - (usually terrible) error messages generated by the old parser.

Fellows <donal.k.fellows@manchester.ac.uk> - - * unix/Makefile.in: Add dependency information relating to tclCompile.h - since when the list of opcodes changes it is usually useful to rebuild - everything that depends on it (but which is nonetheless a small - fraction of the total set of Tcl source files). - - ***POTENTIAL INCOMPATIBILITY*** for bytecode savers/loaders. See below - - * generic/tclCompCmds.c (TclCompileSwitchCmd): Arrange for very simple - [switch] invokations to be compiled into hash lookups into jump tables; - only a very specific kind of [switch] can be safely compiled this way, - but that happens to be the most common kind. This makes around 5-10% - difference to the speed of execution of clock.test. - * generic/tclExecute.c (TEBC:INST_JUMP_TABLE): New instruction to allow - for jumps to locations looked up in a hashtable.

Also silenced a warning that some compilers gave - about the excessively long constant for JULIAN_SEC_POSIX_EPOCH. Also - fixed a bug where [clock format] would fail in the :localtime zone for - times before the Posix Epoch. Thanks to Miguel Sofer for pointing out - all of these. Also rationalized the code a little bit by moving parts - of [clock scan] into C, eliminating some code that was duplicated in - the C and Tcl layers. - -2005-11-29 Kevin Kenny <kennykb@acm.org> - - * generic/tclBasic.c: Moved a big part of [clock format] down - * generic/tclClock.c: to the C level in order to make it go faster. - * generic/tclInt.h: Preliminary measurements suggest that it - * generic/clock.tcl: more than doubles in speed with this change. - -2005-11-29 Donal K. Fellows <donal.k.fellows@manchester.ac.uk> - - * generic/tclCmdIL.c (Tcl_LsearchObjCmd): Allow [lsearch -regexp] to - process REs that contain backreferences.

+ prior to the Common Era, and added the missing %EE format group to
+ indicate the era.
+ * tools/makeTestCases.tcl: Added code to make sure that %U and %V
+ format groups are included in the tests. (The code depends on %U and %V
+ formatting working correctly when 'makeTestCases.tcl' is run, rather

+
+2006-07-20 Daniel Steffen <das@users.sourceforge.net>
+
+ * macosx/tclMacOSXNotify.c (Tcl_InitNotifier, Tcl_WaitForEvent): create
+ notifier thread lazily upon first call to Tcl_WaitForEvent() rather
+ than in Tcl_InitNotifier(). Allows calling exeve() in processes where
+ the event loop has not yet been run (Darwin's execve() fails in
+ processes with more than one thread), in particular allows embedders to
+ call fork() followed by execve(), previously the pthread_atfork() child
+ handler's call to Tcl_InitNotifier() would immediately recreate the
+ notifier thread in the child after a fork.
+
+ * macosx/tclMacOSXFCmd.c (TclMacOSXCopyFileAttributes): add support
+ * macosx/tclMacOSXNotify.c (Tcl_InitNotifier): for weakly
+ * unix/tclUnixInit.c (Tcl_GetEncodingNameFromEnvironment): importing
+ symbols not available on OSX 10.2 or 10.3, enables binaires built on

+ * macosx/Tcl.xcodeproj/project.pbxproj: enable weak-linking; turn on
+ extra warnings.
+ * macosx/README: document how to enable weak-linking; cleanup.
+ * unix/tclUnixPort.h: add support for weak-linking; conditionalize
+ AvailabilityMacros.h inclusion; only disable realpath on 10.2 or earlier

+ * unix/tclLoadDyld.c (TclpLoadMemoryGetBuffer): change runtime Darwin
+ * unix/tclUnixInit.c (TclpInitPlatform): release check to use

+ * unix/tclUnixFCmd.c (DoRenameFile, TclpObjNormalizePath): add runtime
+ Darwin release check to determine if realpath is threadsafe.
+ * unix/configure.in: add check on Darwin for compiler support of weak
+ * unix/tcl.m4: import and for AvailabilityMacros.h header;
+ move Darwin specific checks & defines that are only relevant to the tcl

+2006-07-13 Andreas Kupries <andreask@activestate.com>
+
+ * unix/tclUnixPort.h: Added the inclusion of <AvailabilityMacros.h>.
+ The missing header caused the upcoming #if conditions to wrongly

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

+ after all thread TSD has been garbage-collected.
+
+2006-07-05 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclParseExpr.c: Completely new expression parser that
+ builds a parse tree instead of operating with deep recursion. This
+ corrects reports of stack-blowing crashes parsing long expressions [Bug
+ 906201] and replaces a fundamentally O(N^2) algorithm with an O(N) one
+ [RFE 903765]. The new parser is better able to generate error messages
+ that clearly report both the nature and context of the syntax error
+ [Bugs 1029267, 1381715]. For now, the code for the old parser is still
+ present and can be activated with a "#define OLD_EXPR_PARSER 1". This
+ is for the sake of a clean implementation patch, and for ease of
+ benchmarking. The new parser is non-recursive, so much lighter in stack
+ consumption, but it does use more heap, so there may be cases where
+ parsing of long expressions that succeeded with the old parser will
+ lead to out of memory panics with the new one. There are still more
+ improvements possible on that point, though significant progress may
+ require changes to the Tcl_Token specifications documented for the
+ public Tcl_Parse*() routines.
+ ***POTENTIAL INCOMPATIBILITY*** for any callers that rely on the exact
+ (usually terrible) error messages generated by the old parser. This
+ includes a large number of tests in the test suite.
+
+ * generic/tclInt.h: Replaced TclParseWhiteSpace() with
+ * generic/tclParse.c: TclParseAllWhiteSpace() which is what
+ * generic/tclParseExpr.c: all the callers really needed. Breaking
+ whitespace runs at newlines is useful only to the command parsing
+ function, and it can call the file scoped routine ParseWhiteSpace() to
+ do that.
+
+ * tests/expr-old.test: Removed knownBug constraints that masked
+ * tests/expr.test: failures due to revised error messages.
+ * tests/parseExpr.test:
+
+2006-06-20 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclIOUtil.c: Changed default configuration to
+ * generic/tclInt.decls: #undef USE_OBSOLETE_FS_HOOKS which disables
+ * generic/tclTest.c: access to the Tcl 8.3 internal routines for
+ hooking into filesystem operations. Everyone ought to have migrated to
+ Tcl_Filesystems by now.
+ ***POTENTIAL INCOMPATIBILITY*** for any code still stuck in the
+ pre-Tcl_Filesystem era.
+
+ * generic/tclIntDecls.h: make genstubs
+ * generic/tclStubInit.c:
+
+ * generic/tclStrToD.c: Removed dead code that permitted disabling of
+ recognition of the new 0b and 0o numeric formats.
+
+ * generic/tclExecute.c: Removed dead code that implemented alternative
+ * generic/tclObj.c: design where numeric values did not
+ automatically narrow to the smallest Tcl_ObjType required to hold them.
+
+ * generic/tclCmdAH.c: Removed dead code that was old implementation
+ of [format].
+
+2006-06-14 Daniel Steffen <das@users.sourceforge.net>
+
+ * unix/tclUnixPort.h (Darwin): support for MAC_OS_X_VERSION_MAX_ALLOWED
+ define from AvailabilityMacros.h: override configure detection and only
+ use API available in the indicated OS version or earlier.
+
+2006-06-14 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * doc/format.n, doc/scan.n: Added examples for converting between

+
+2006-06-13 Donal K. Fellows <dkf@users.sf.net>
+
+ * unix/tclLoadDl.c (TclpDlopen): Workaround for a compiler bug in Sun
+ Forte 6. [Bug 1503729]
+
+2006-06-06 Don Porter <dgp@users.sourceforge.net>
+
+ * doc/GetStdChan.3: Added recommendation that each call to

+
+2006-06-05 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * doc/Alloc.3: Added documentation of promise that Tcl_Realloc(NULL,x)
+ is the same as Tcl_Alloc(x), as discussed in comp.lang.tcl. Also fixed
+ nonsense sentence to say something meaningful.
+
+2006-05-29 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/tcl.h (Tcl_DecrRefCount): use if/else construct to allow
+ placement in unbraced outer if/else conditions. (jcw)
+
+2006-05-27 Daniel Steffen <das@users.sourceforge.net>
+
+ * macosx/tclMacOSXNotify.c: implemented pthread_atfork() handler that
+ * unix/tcl.m4 (Darwin): recreates CoreFoundation state and notifier
+ thread in the child after a fork(). Note that pthread_atfork is
+ available starting with Tiger only. Because vfork() is used by the core
+ on Darwin, [exec]/[open] are not affected by this fix, only extensions
+ or embedders that call fork() directly (such as TclX). However, this
+ only makes fork() safe from corefoundation tcl with --disable-threads;
+ as on all platforms, forked children may deadlock in threaded tcl due
+ to the potential for stale locked mutexes in the child. [Patch 923072]

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

+
+2006-05-23 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * doc/chan.n, doc/refchan.n: Tighten up the documentation to follow a
+ slightly more consistent style with regard to argument capitalization.
+
+2006-05-13 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclProc.c (ProcCompileProc): When a bump of the compile epoch
+ forces the re-compile of a proc body, take care not to overwrite any
+ Proc struct that may be referred to on the active call stack. This
+ fixes [Bug 1482718]. Note that the fix will not be effective for code
+ that calls the private routine TclProcCompileProc() directly.
+
+2006-05-13 Daniel Steffen <das@users.sourceforge.net>

+2006-05-05 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclMain.c (Tcl_Main): Corrected flaw that required

+ * generic/tclIO.c (ReadChars): Added check, panic and commentary to a
+ piece of code which relies on BUFFER_PADDING to create enough space at

+ OK, and the panic is as a precaution if someone twiddled the

+ the Utf bug below it was possible to completely wreck the buffer data
+ structures, eventually crashing Tcl.
+
+ * generic/tclEncoding.c (UtfToUtfProc): Stop accessing memory beyond
+ the end of the input buffer when TCL_ENCODING_END is set and the last
+ bytes of the buffer start a multi-byte sequence. This bug contributed
+ to [Bug 1462248].

+ * generic/tcl.h: where the "truncateProc" is defined at, and
+ * generic/tclIO.c: moved all channel drivers of Tcl to v5.
+ * generic/tclIOGT.c, generic/tclIORChan.c, unix/tclUnixChan.c:
+ * unix/tclUnixPipe.c, win/tclWinChan.c, win/tclWinConsole.c:

+
+2006-03-27 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclExecute.c: Merge INST_MOD computation in with the
+ INST_?SHIFT instructions, which also operate only on two integral
+ values. Also corrected flaw that made INST_BITNOT of wide values
+ require mp_int calculations. Also corrected type that missed optimized
+ handling of the tclBooleanType by the TclGetBooleanFromObj macro.
+
+ * changes: Updates for another RC.
+
+2006-03-25 Don Porter <dgp@users.sourceforge.net>

+ to use mp_int calculations.
+
+2006-03-24 Kevin Kenny <kennykb@acm.org>
+
+ * generic/tclExecute.c (TclExecuteByteCode): Added a couple of missing
+ casts to 'int' that were affecting compilablity on VC6.
+
+2006-03-24 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclEncoding.c: Reverted latest change [Bug 506653] since it
+ reportedly killed test performance on Windows.
+
+ * generic/tclExecute.c: Revised INST_EXPON implementation to do
+ calculations in native types as much as possible, moving to mp_ints
+ only when necessary.
+
+2006-03-23 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclExecute.c: Merged INST_EXPON handling in with the other
+ binary operators that operate on all number types (INST_ADD, etc.).
+
+ * tests/env.test: With case preserved (see 2006-03-21 commit) be sure
+ to do case-insensitive filtering. [Bug 1457065]
+
+2006-03-23 Reinhard Max <max@suse.de>
+
+ * unix/tcl.spec: Cleaned up and completed the spec file. An RPM can now
+ be built from the tcl source distribution with "rpmbuild -tb <tarball>"
+
+2006-03-22 Reinhard Max <max@suse.de>
+
+ * tests/stack.test: Run the stack tests in subshells, so that they are
+ reported as failed tests rather than bugs in the test suite if the
+ recursion causes a segfault.
+
+2006-03-21 Don Porter <dgp@users.sourceforge.net>
+
+ * changes: Updates for another RC.
+
+ * generic/tclStrToD.c: One of the branches of AccumulateDecimalDigit

+2006-03-21 Daniel Steffen <das@users.sourceforge.net>
+
+ * generic/tclInt.decls: implement globbing for HFS creator & type
+ * macosx/tclMacOSXFCmd.c:codes and 'hidden' flag, as documented in
+ * tests/macOSXFCmd.test: glob.n; objectified OSType handling in [glob]

+ * generic/tclIntPlatDecls.h:
+ * generic/tclStubInit.c: make genstubs
+
+2006-03-20 Andreas Kupries <andreask@activestate.com>
+
+ * win/Makefile.in (install-libraries): Generate tcl8/8.4 directory
+ under Windows as well (cygwin Makefile). Related entry: 2006-03-07,
+ dgp. This moved the installation of http from 8.2 to 8.4, partially. A
+ fix of the required directory creation was done for unix on Mar 10,
+ without entry in the Changelog. This entry is for the fix of the
+ directory creation under Windows.
+
+ * unix/installManPage: There is always one even more broken "sed".
+ Moved the # comment starting character in the sed script to the
+ beginning of their respective lines. The AIX sed will not recognize
+ them as comments otherwise :( The actual text stays indented for better
+ association with the commands they belong to.
+
+2006-03-20 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * tests/cmdAH.test, tests/fCmd.test, tests/unixFCmd.test:

+
+2006-03-18 Vince Darley <vincentdarley@sourceforge.net>
+
+ * generic/tclFileName.c:
+ * doc/FileSystem.3:
+ * tests/fileName.test: Fix to [Bug 1084705] so that 'glob -nocomplain'
+ finally agrees with its documentation and doesn't swallow genuine
+ errors.
+
+ ***POTENTIAL INCOMPATIBILITY*** for scripts that assumed '-nocomplain'
+ removes the need for 'catch' to deal with non-understood path names.
+
+ Small optimisation to implementation of pattern==NULL case of TclGlob,
+ and clarification to the documentation. [Tclvfs bug 1405317]
+
+2006-03-18 Vince Darley <vincentdarley@sourceforge.net>
+
+ * tests/fCmd.test: added knownBug test case for [Bug 1394972]
+
+ * tests/winFCmd.test:
+ * tests/tcltest.test: corrected tests to better account for behaviour
+ of writable/non-writable directories on Windows 2000/XP. This, with the
+ previous patches, closes [Bug 1193497]
+
+2006-03-17 Andreas Kupries <andreask@activestate.com>
+
+ * doc/chan.n: Updated with documentation for the commands 'chan create'

+
+ * doc/open.n: Documented the changed behaviour of 'a'ppend mode.
+
+ * tests/io.test (io-43.1 io-44.[1234]): Rewritten to be self-contained
+ with regard to setup and cleanup. [Bug 681793].
+
+ * generic/tclIOUtil.c (TclGetOpenMode): Added the flag O_APPEND to the
+ list of POSIX modes used when opening a file for 'a'ppend. This
+ enables the proper automatic seek-to-end-on-write by the OS. See [Bug
+ 680143] for longer discussion.
+
+ * tests/ioCmd.test (iocmd-13.7.*): Extended the testsuite to check the
+ new handling of 'a'.
+
+2006-03-15 Andreas Kupries <andreask@activestate.com>
+
+ * tests/socket.test: Extended the timeout in socket-11.11 from 10 to 40
+ seconds to allow for really slow machines. Also extended
+ actual/expected results with value of variable 'done' to make it
+ clearer when a test fails due to a timeout. [Bug 792159].
+
+2006-03-15 Vince Darley <vincentdarley@sourceforge.net>
+
+ * win/fCmd.test: add proper test constraints so the new tests don't run
+ on Unix.
+
+2006-03-14 Andreas Kupries <andreask@activestate.com>
+
+ * generic/tclPipe.c (TclCreatePipeline): Modified the processing of
+ pipebars to fail if the last bar is followed only by redirections. [Bug
+ 768659]
+
+2006-03-14 Andreas Kupries <andreask@activestate.com>
+
+ * doc/fconfigure.n: Clarified that -translation is binary is reported
+ as lf when queried, because it is identical to lf, except for the
+ special additional behaviour when setting it. [Bug 666770].
+
+2006-03-14 Andreas Kupries <andreask@activestate.com>
+
+ * doc/clock.n: Removed double-quotes around section title NAME; not
+ needed.
+ * unix/installManpage: Reverted part to handle double-quotes in section
+ NAME, chokes older sed installations.
+
+2006-03-14 Andreas Kupries <andreask@activestate.com>
+
+ * library/tm.tcl (::tcl::tm::Defaults): Fixed handling of environment
+ variable TCLX.y_TM_PATH, bad variable reference. [Bug 1448251]. Thanks
+ to Julian Noble.
+
+2006-03-14 Vince Darley <vincentdarley@sourceforge.net>
+
+ * win/tclWinFile.c: updated patch to deal with 'file writable' issues
+ on Windows XP/2000.
+ * generic/tclTest.c:
+ * unix/tclUnixTest.c:
+ * win/tclWinTest.c:
+ * tests/fCmd.test: updated test suite to deal with correct permissions
+ setting and differences between XP/2000 and 95/98 3 tests still fail;
+ to be dealt with shortly
+
+2006-03-13 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclEncoding.c: Report error when an escape encoding is
+ missing one of its sub-encodings [Bug 506653].
+
+ * unix/configure.in: Revert change from 2005-07-26 that sometimes
+ * unix/configure: added $prefix/share to the tcl_pkgPath. See
+ [Patch 1231015]. autoconf-2.59.
+
+2006-03-10 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclProc.c (ObjInterpProcEx):
+ * tests/apply.test (apply-5.1): Fix [apply] error messages so that they
+ quote the lambda expression [Bug 1447355].
+
+2006-03-10 Zoran Vasiljevic <vasiljevic@users.sourceforge.net>
+
+ -- Summary of changes fixing [Bug 1437595] --
+
+ * generic/tclEvent.c: Cosmetic touches and identation
+ * generic/tclInt.h: Added TclpFinalizeSockets() call.
+
+ * generic/tclIO.c: Calls TclpFinalizeSockets() as part of the
+ TclFinalizeIOSubsystem().
+
+ * unix/tclUnixSock.c: Added no-op TclpFinalizeSockets().
+
+ * win/tclWinPipe.c, win/tclWinSock.c: Finalization of sockets/pipes is
+ now solely done in TclpFinalizeSockets() and TclpFinalizePipes() and
+ not over the thread-exit handler, because the order of actions the Tcl
+ generic core will impose may result in cores/hangs if the thread exit
+ handler tears down corresponding subsystem(s) too early.
+
+2006-03-10 Vince Darley <vincentdarley@sourceforge.net>
+
+ * win/tclWinFile.c: previous patch breaks tests, so removed.
+
+2006-03-09 Vince Darley <vincentdarley@sourceforge.net>

+
+ * changes: Update in prep. for 8.5a4 release.
+
+ * unix/Makefile.in: Package http 2.5.2 requires Tcl 8.4, so the
+ * win/Makefile.in: *.tm installation has to be placed in an "8.4"
+ directory, not an "8.2" directory.
+
+2006-03-06 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclBasic.c: Revised handling of TCL_EVAL_* flags to

+
+2006-03-03 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclPathObj.c: Revised yesterday's fix for [Bug 1379287] to
+ work on Windows.

+
+2006-03-02 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclPathObj.c: Fix for failed normalization of paths
+ * tests/fileSystem.test: with /../ that lead back to the root of
+ the filesystem, like /foo/.. [Bug 1379287]
+
+2006-03-01 Reinhard Max <max@suse.de>
+
+ * unix/installManPage: Fix the script for manpages that have quotes
+ around the .SH arguments, as doctools produces them [Bug 1292145]. Some
+ minor cleanups and improvements.
+
+2006-02-28 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclBasic.c: Corrections to be sure that TCL_EVAL_GLOBAL
+ * tests/namespace.test: evaluations act the same as [uplevel #0]
+ * tests/parse.test: evaluations, even when execution traces or
+ * tests/trace.test: invocations of [::unknown] are present.
+ [Bug 1439836].
+
+2006-02-22 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclBasic.c: Corrected a few bugs in how [namespace

+ [Patch 958222]
+
+2006-02-17 Don Porter <dgp@users.sourceforge.net>

+
+2006-01-26 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * unix/tclUnixChan.c (TclpOpenFileChannel): Tidy up and comment the
+ mess to do with setting up serial channels. This (deliberately) breaks
+ a broken FreeBSD port, indicates what we're really doing, and reduces
+ the amount of conditional compilation sections for better maintenance.
+
+2006-01-25 Donal K. Fellows <dkf@users.sf.net>
+
+ * unix/tclUnixInit.c (TclpInitPlatform): Improved conditions on when to

+ 1412695]; thanks to Uwe Traum.
+
+2006-01-16 Reinhard Max <max@suse.de>
+
+ * generic/tclPipe.c (FileForRedirect): Prevent nameString from being
+ freed without having been initialized.
+ * tests/exec.test: Added a test for the above.
+
+2006-01-12 Zoran Vasiljevic <vasiljevic@users.sourceforge.net>
+
+ * generic/tclPathObj.c (Tcl_FSGetInternalRep): backported patch from

+
+2006-01-12 Vince Darley <vincentdarley@sourceforge.net>
+
+ * win/tclWinFile.c: fix to sharing violation [Bug 1366227]
+
+2006-01-11 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclBasic.c: Moved Tcl_LogCommandInfo from tclBasic.c to
+ * generic/tclNamesp.c: tclNamesp.c to get access to identifier with
+ * tests/error.test (error-7.0): file scope. Added check for traces on
+ ::errorInfo, and when present fall back to contruction of the stack
+ trace in the variable so that write trace notification timings are
+ compatible with earlier Tcl releases. This reduces, but does not
+ completely eliminate the ***POTENTIAL INCOMPATIBILITY*** created by the
+ 2004-10-15 commit. [Bug 1397843].
+
+2006-01-10 Daniel Steffen <das@users.sourceforge.net>
+
+ * unix/configure: add caching, use AC_CACHE_CHECK instead of
+ * unix/configure.in: AC_CACHE_VAL where possible, consistent message
+ * unix/tcl.m4: quoting, sync relevant tclconfig/tcl.m4 changes
+ and gratuitous formatting differences, fix SC_CONFIG_MANPAGES with
+ default argument, Darwin improvements to SC_LOAD_*CONFIG.
+
+2006-01-09 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclNamesp.c (NamespaceInscopeCmd): [namespace inscope]
+ * tests/namespace.test: commands were not reported by [info level]

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

+
+2006-01-05 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * unix/tcl.m4 (TCL_CONFIG_SYSTEM): Factor out the code to determine
+ the operating system version number, as it was replicated in several
+ places.
+
+2006-01-04 David Gravereaux <davygrvy@pobox.com>
+
+ * win/tclAppInit.c: WIN32 native console signal handler removed. This

+ not its name to "stop the bleeding" on [Bug 1386377]. This is *not* a
+ good long-term solution, but there may not be one.
+
+ * libtommath/bn_mp_sqrt.c: Improved the initial approximation to the
+ square root, roughly doubling the speed of the routine. (This is a
+ local change that needs to be communicated to Tom.)
+
+ * win/Makefile.in: Corrected a bug where tommath_class.h and
+ tommath_superclass.h were not installed, making it impossible for
+ client code to compile against the tommath stubs.
+
+ * library/tzdata: Updated to Olson's tzdata2005r. (Latest changes to
+ Daylight Saving Time in Canada, plus redefinition of the Posix-style
+ zones [e.g., EST5EDT] to be locale-independent.)
+
+ * libtommath: Updated to Tom St.Denis's release 0.37.
+
+2005-12-20 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * generic/tclThreadAlloc.c (Tcl_GetMemoryInfo): Format values as longs
+ and not ints, so they are less likely to wrap on 64-bit machines.
+
+2005-12-19 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclCmdMZ.c: Modified [string is double] to use
+ * tests/string.test: TclParseNumber() to parse trailing whitespace.
+ Ensures consistency, and makes it easier to cleanup after invalid
+ internal reps left behind by parsing [Bugs 1360532 1382287].
+
+ * generic/tclParseExpr.c: Added TCL_PARSE_NO_WHITESPACE to
+ * generic/tclScan.c: TclParseNumber() calls since [scan] and [expr]
+ * tests/scan.test: parsing don't want spaces in parsed numbers.
+
+ * generic/tclInt.h: Added TCL_PARSE_NO_WHITESPACE flag to the
+ * generic/tclStrToD.c: TclParseNumber() interface.
+
+2005-12-19 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>

+
+2005-12-18 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * generic/tclCompCmds.c (TclCompileDictCmd): Ensure that we only do an
+ 'endCatch' when there's a preceding 'beginCatch'. [Bug 1382528] Many
+ thanks to Anton Kovalenko for finding this and pointing out that it was
+ a catch stack handling problem!
+
+2005-12-14 Daniel Steffen <das@users.sourceforge.net>
+
+ * generic/tclIOUtil.c: workaround gcc warning "comparison is always

+
+ * generic/tclExecute.c (TEBC:DICT_FIRST,DICT_DONE): Only decrease the

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

+
+2005-12-09 Mo DeJong <mdejong@users.sourceforge.net>
+
+ * win/configure: Regen.
+ * win/tcl.m4 (SC_CONFIG_CFLAGS): Define MACHINE for gcc builds. The

+
+2005-12-09 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * tests/lsearch.test (lsearch-10.8..10): If the -start is off the end,

+ at all. [Bug 1374778]
+
+2005-12-08 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * win/Makefile.in, win/makefile.vc: Add Win x64 and CE build support
+ * win/tcl.m4, win/configure: CE still requires C code fixes.
+
+ * generic/tcl.h: use struct __stat64 (not _stat64) for MSC_VER >= 1400
+ (i.e. latest Platform SDK).
+
+2005-12-07 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * doc/socket.n: Cross-referenced the socket documentation better to the
+ fconfigure documentation on the topic of asynch sockets.
+ * doc/fconfigure.n: Added keyword to documentation of -blocking option
+ so that people looking for "asynch" can find it as well.
+
+2005-12-05 Daniel Steffen <das@users.sourceforge.net>
+
+ * unix/tclUnixPort.h (Darwin): fix incorrect __DARWIN_UNIX03 configure
+ overrides that were originally copied from Darwin CVS (rdar://3693001)
+
+2005-12-05 Kevin B. Kenny <kennykb@acm.org>
+
+ * tools/tclZIC.tcl: Updated to reflect changes in calling sequence when
+ GetJulianDateFromEraYearMonthDay moved to C.
+ * library/tzdata: Regenerated from Olson's tzdata2005p.tar.gz - the
+ 'systemv' changes appear not to affect Tcl's processing of the dates.
+
+2005-12-05 Daniel Steffen <das@users.sourceforge.net>
+
+ * unix/configure.in: move check for fts API to configure.in and run it
+ * unix/tcl.m4: on all platforms, since Linux glibc2 and *BSDs
+ also have this; using fts is more efficient than a recursive
+ opendir/readdir.
+ * unix/tclUnixFCmd.c (TraverseUnixTree): add support to fts code for
+ platforms with stat64.
+ * unix/configure:
+ * unix/tclConfig.h.in: regen.
+
+2005-12-05 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * unix/configure: Use fts file API on Darwin if available.
+ * unix/tcl.m4: Addresses file delete issues in readdir noted

+ Remove redundant stat call for each file in DoCopyFile. (steffen)
+
+2005-12-02 Kevin B. Kenny <kennykb@acm.org>
+
+ * generic/tclClock.c: Moved a tiny bit more of [clock format] from run
+ * library/clock.tcl: time to compile time, and fixed a l10n bug in the
+ process. [Bug 1371446]. Also, conditoned the call to SetupTimeZone to
+ speed the common case where TZData($timezone) already exists, and
+ achieved a puny speedup by making ::tcl::clock::getenv not throw
+ errors.
+ * unix/Makefile.in: Made some changes to support a 'make' command that
+ is present on some antiquated versions of Solaris.
+
+2005-12-01 Kevin B. Kenny <kennykb@acm.org>
+
+ * library/clock.tcl: Continued rationalizing the code, eliminating
+ numerous redundant [mc] calls. Added another time boost by precompiling
+ a [::format] command to do the bulk of the work of [clock format].
+
+2005-12-01 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * unix/Makefile.in: Add remaining dependency info. While automated
+ maintenance of this information would be good, having it at all is much
+ better than a poke in the eye with a sharp stick...
+
+2005-12-01 Daniel Steffen <das@users.sourceforge.net>
+
+ * generic/tclClock.c: fix warning.
+
+ * unix/tcl.m4 (Darwin): fix error when MACOSX_DEPLOYMENT_TARGET unset
+ * unix/configure: regen.
+
+2005-11-30 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * unix/Makefile.in: Add dependency information relating to tclCompile.h
+ since when the list of opcodes changes it is usually useful to rebuild
+ everything that depends on it (but which is nonetheless a small
+ fraction of the total set of Tcl source files).
+
+ ***POTENTIAL INCOMPATIBILITY*** for bytecode savers/loaders. See below
+
+ * generic/tclCompCmds.c (TclCompileSwitchCmd): Arrange for very simple
+ [switch] invokations to be compiled into hash lookups into jump tables;
+ only a very specific kind of [switch] can be safely compiled this way,
+ but that happens to be the most common kind. This makes around 5-10%
+ difference to the speed of execution of clock.test.
+ * generic/tclExecute.c (TEBC:INST_JUMP_TABLE): New instruction to allow
+ for jumps to locations looked up in a hashtable. Requires a new AuxData
+ type, tclJumptableInfoType (supported by the functions DupJumptableInfo
+ and FreeJumptableInfo in tclCompCmds.c) so anything that saves bytecode
+ containing this *must* be updated!
+
+2005-11-30 Kevin Kenny <kennykb@acm.org>
+
+ * generic/tclClock.c: Fixed a bad refcount in previous commit that led
+ to a corrupted heap. Also silenced a warning that some compilers gave
+ about the excessively long constant for JULIAN_SEC_POSIX_EPOCH. Also
+ fixed a bug where [clock format] would fail in the :localtime zone for
+ times before the Posix Epoch. Thanks to Miguel Sofer for pointing out
+ all of these. Also rationalized the code a little bit by moving parts
+ of [clock scan] into C, eliminating some code that was duplicated in
+ the C and Tcl layers.
+
+2005-11-29 Kevin Kenny <kennykb@acm.org>
+
+ * generic/tclBasic.c: Moved a big part of [clock format] down
+ * generic/tclClock.c: to the C level in order to make it go faster.
+ * generic/tclInt.h: Preliminary measurements suggest that it
+ * generic/clock.tcl: more than doubles in speed with this change.
+
+2005-11-29 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * generic/tclCmdIL.c (Tcl_LsearchObjCmd): Allow [lsearch -regexp] to
+ process REs that contain backreferences. This expensive mode of
+ operation is only used if the RE would otherwise cause a compilation
+ failure. [Bug 1366683]
+
+2005-11-28 Kevin Kenny <kennykb@acm.org>
+
+ * tools/tclZIC.tcl (convertTimeOfDay): Corrected a typo that caused
+ wrong DST transitions in any time zone where the transition is
+ specified as local Standard Time (as opposed to wall-clock or UTC).
+ (Also updated the code to be bignum-safe.)
+ * tests/clock.test (clock-51.1): Added regression test for the above.
+ * library/tzdata: Updated to Olson's 'tzdata2005o' (changes for Cuba,
+ Nicaragua, Jordan, and Georgia) and regenerated. Thanks to Paul
+ Mackerras for reporting this problem.
+
+2005-11-27 Daniel Steffen <das@users.sourceforge.net>
+
+ * unix/tcl.m4 (Darwin): add 64bit support, check for Tiger copyfile(),
+ add CFLAGS to SHLIB_LD to support passing -isysroot in env(CFLAGS) to
+ configure (flag can't be present twice, so can't be in both CFLAGS and
+ LDFLAGS during configure), don't use -prebind when deploying on 10.4,
+ define TCL_IO_TRACK_OS_FOR_DRIVER_WITH_BAD_BLOCKING (rdar://3171542).
+ (SC_ENABLE_LANGINFO, SC_TIME_HANDLER): add/fix caching, fix obsolete
+ autoconf macros. Sync with tk/unix/tcl.m4.
+
+ * unix/configure.in: fix obsolete autoconf macros, sync gratuitous
+ formatting/ordering differences with tk/unix/configure.in.
+
+ * unix/Makefile.in: add CFLAGS to tclsh/tcltest link to make executable
+ linking the same as during configure (needed to avoid losing any linker
+ relevant flags in CFLAGS, in particular flags that cannot be in
+ LDFLAGS). Avoid concurrent linking of tclsh and compiling of
+ tclTestInit.o or xtTestInit.o during parallel make.
+ (checkstubs, checkdoc, checkexports): dependency and Darwin fixes
+ (dist): add new macosx files.
+
+ * unix/tclLoadDyld.c (TclpDlopen): use NSADDIMAGE_OPTION_WITH_SEARCHING
+ on second NSAddImage only. [Bug 1204237]
+ (TclGuessPackageName): should not be MODULE_SCOPE.
+ (TclpLoadMemory): ppc64 and endian (i386) fixes, add support for

+
+ * unix/tclUnixFCmd.c:
+ * macosx/tclMacOSXFCmd.c: ppc64 and endian (i386) fixes.
+ (TclMacOSXCopyFileAttributes): add support for new Tiger copyfile() API
+ to enable copying of xattrs & ACLs by [file copy].
+
+ * generic/tcl.h: add Darwin specifc configure overrides for TCL_WIDE
+ defines to support fat compiles of ppc and ppc64 at the same time,
+ (replaces Darwin CVS fix by emoy, rdar://3693001). add/correct location
+ of version numbers in macosx files.
+
+ * generic/tclInt.h: clarify fat compile comment.
+
+ * unix/tclUnixPort.h: add Darwin specifc configure overrides to support
+ fat compiles, where configure runs only once for multiple architectures
+ (replaces Darwin CVS fix by emoy, rdar://3693001).
+
+ * macosx/tclMacOSXBundle.c:
+ * macosx/tclMacOSXNotify.c:
+ * unix/tclUnixNotfy.c:

+ projects for Xcode 2.2 on 10.4, Xcode 1.5 on 10.3 & ProjectBuilder on
+ 10.2, with native tcltest targets and support for universal (fat)
+ compiles.
+
+ * macosx/README: clarification/cleanup, document new Xcode projects and

+
+ * unix/Makefile.in:
+ * unix/aclocal.m4:
+ * unix/configure.in:
+ * unix/dltest/Makefile.in:
+ * macosx/configure.ac (new file): add support for inclusion of
+ unix/configure.in by macosx/configure.ac, allows generation of a config
+ headers enabled configure script in macosx (required by Xcode
+ projects).
+
+ * macosx/GNUmakefile: rename from Makefile to avoid overwriting by
+ configure run in tcl/macosx, add support for reusing configure cache,
+ build target fixes, remove GENERIC_FLAGS override now handled by
+ tcl.m4.
+
+ * generic/tcl.decls: add Tcl_Main declaration as comment to avoid
+ 'checkstubs' target complaining about it missing from stubs.

+
+2005-11-21 Andreas Kupries <andreask@activestate.com>
+
+ * unix/Makefile.in (install-libraries): Updated Makefile to new
+ * win/Makefile.in (install-libraries): version of the http package.
+ This fixes the ifneeded/provide mismatch reported when trying to
+ require http. Should we maybe try to automatically extract the version
+ number from the http code to prevent future breakage ?
+
+ This follows the update of the version number by dgp on Nov 15 (No
+ entry found in the ChangeLog).
+
+2005-11-20 Joe English <jenglish@users.sourceforge.net>
+
+ * generic/tclStubLib.c: Don't set tclStubsPtr to 0 when

+
+2005-11-18 Miguel Sofer <msofer@users.sf.net>
+
+ * tests/trace.test (trace-34.5): [Bug 1047286], added a second test
+ illustrating the role of "ns in callStack" in the ns's visibility
+ during deletion traces.
+
+2005-11-18 Kevin B. Kenny <kennykb@acm.org>
+
+ * doc/clock.n: Restored several missing lines near the %w format group
+ so that %w and %W are documented with their actual behaviour. [Bug
+ 1359183]
+
+2005-11-18 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * generic/tclIO.c (TclFinalizeIOSubsystem): preserve statePtr until we
+ retrieve the next statePtr from it.
+
+2005-11-18 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclObj.c (GetBignumFromObj): replace NULL with

+ (the corresponding branch is eliminated by the optimiser otherwise).
+
+2005-11-18 Andreas Kupries <andreask@activestate.com>
+
+ * generic/tclIO.c (TclFinalizeIOSubsystem): Applied Pat Thoyts' patch
+ for [Bug 1359094]. This moves the retrieval of the next channel state
+ to the end of the loop, as the called closeproc may close other
+ channels, i.e. modify the list we are iterating, invalidating any
+ pointer retrieved earlier.
+
+2005-11-18 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclListObj.c: Restored the SetListFromAny routine to the
+ * generic/tclObj.c: "list" Tcl_ObjType, and restored the
+ Tcl_RegisterObjType() call for "list". This addresses the needs of some
+ "bridge" extensions to examine whether the Tcl_ObjType of a Tcl_Obj is
+ that of the "list" Tcl_ObjType.
+
+2005-11-18 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * library/http/http.tcl (http::geturl): Improved syntactic validation

+
+2005-11-12 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclBasic.c (Tcl_DeleteCommandFromToken):
+ * generic/tclObj.c (Tcl_GetCommandFromObj): more partial fixes for

+ deleted cannot be made reusable by a delete trace.
+
+2005-11-12 Donal K. Fellows <dkf@users.sf.net>
+
+ * generic/tclNamesp.c (Tcl_FindCommand): Do not find commands in dead
+ namespaces on the path. Partial fix for [Bug 1354540].
+
+2005-11-11 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclInt.h: Revised TclParseNumber interface to enable
+ * generic/tclScan.c: revision to the [scan] command implementation
+ * generic/tclStrToD.c: to permit tests scan-4.44,55 to pass again.
+ [Bug 1348067].
+
+2005-11-11 Miguel Sofer <msofer@users.sf.net>
+
+ * generic/tclBasic.c (Tcl_DeleteCommandFromToken):
+ * generic/tclObj.c (Tcl_GetCommandFromObj): bump the cmd epoch early
+ to insure that cached references to this command are invalidated.
+ Partial fix for [Bug 1352734] - at least insures that namespace-51.13
+ does not cause a panic. The test is still marked as knownbug, pending
+ resolution of what is actually the correct return value ([Bug
+ 1354540])
+
+2005-11-09 Kevin B. Kenny <kennykb@acm.org>
+
+ * generic/tclTimer.c: Changed [after] so that it behaves correctly
+ * tests/timer.test: with negative arguments [Bug 1350293] and

+
+2005-11-08 Don Porter <dgp@users.sourceforge.net>
+
+ * tests/compile.test: Updated tests with changed behavior

+
+ * unix/tclUnixFCmd.c (MAX_READDIR_UNLINK_THRESHOLD): reduce to 130

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

+2005-11-08 Don Porter <dgp@users.sourceforge.net>
+
+ * tests/compExpr-old.test: Updated tests with changed behavior due

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

+
+2005-11-08 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * generic/tclTrace.c (TraceVarEx): Factor out heart of Tcl_TraceVar2
+ (TclTraceVariableObjCmd,TraceVarProc): Use the new internal API to
+ arrange for the clientData to be cleaned up at the same time as the
+ rest of the main trace record. This simplifies the code a bit at the
+ same time.
+
+2005-11-07 Miguel Sofer <msofer@users.sf.net>
+
+ * tests/trace.test (trace-13.2-4): added tests to detect leak, see [Bug

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

+ * generic/tclDate.c: Regenerated.
+
+ * tools/findBadExternals.tcl: Added this script, which locates external

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

+ should not happen, so the bug is not completely fixed.
+ * tests/trace.test (test-18.3-4): added tests for [Bug 1337229] and

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

+2005-10-19 Donal K. Fellows <donal.k.fellows@manchester.ac.uk>
+
+ * generic/tclIORChan.c: General cleanup, removing checks that are

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

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

+ discussion.
+
+ * generic/tcl.h: Fixed bad definition of CRTEXPORT which should have
+ been CRTIMPORT rather. This broke compilation of generic/tclMain.c and

+ 1256937] below.
+
+2005-10-14 Kevin Kenny <kennykb@acm.org>

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

+
+2005-10-10 Donal K. Fellows <donal.k.fellows@man.ac.uk>
+
+ * generic/tclInterp.c (DeleteScriptLimitCallback)

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

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

+
+2005-10-04 Don Porter <dgp@users.sourceforge.net>
+
+ [kennykb-numerics-branch]

+
+2005-10-03 Don Porter <dgp@users.sourceforge.net>
+
+ [kennykb-numerics-branch]
+
+ * generic/tclBasic.c: Re-implemented ExprRoundFunc and

+
+ * generic/tclIOUtil.c (TclLoadFile):
+ * generic/tclInt.h:
+ * unix/tcl.m4:
+ * unix/tclLoadDyld.c: added support for [load]ing .bundle binaries in

+ * unix/tclConfig.h.in: autoheader-2.59
+

+
+2005-05-20 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclParseExpr.c: Corrected parser to recognize all
+ boolean literals accepted by Tcl_GetBoolean, including prefixes like
+ "y" and "f", and to allow "eq" and "ne" as function names in the proper
+ context. [Bug 1201589].
+
+2005-05-19 Donal K. Fellows <dkf@users.sf.net>
+
+ * generic/tclBasic.c (TclEvalObjvInternal): Rewrite for greater
+ clarity; although 'goto' is Bad, the contortions you have to go through
+ to avoid it can be worse...
+
+2005-05-19 Daniel Steffen <das@users.sourceforge.net>
+
+ * macosx/tclMacOSXNotify.c (Tcl_InitNotifier): fixed crashing CFRelease
+ of runLoopSource in Tcl_InitNotifier (reported by Zoran):
+ CFRunLoopAddSource doesn't CFRetain, so can only CFRelease the
+ runLoopSource in Tcl_FinalizeNotifier.
+
+2005-05-18 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclBasic.c (Tcl_ExprBoolean): Rewrite as wrapper around
+ Tcl_ExprBooleanObj.
+
+ * generic/tclCmdMZ.c ([string is boolean/true/false]): Rewrite dropping
+ string-based Tcl_GetBoolean call, so that internal reps are kept for
+ subsequent quick boolean operations.
+
+ * generic/tclExecute.c: Dropped most special handling of the "boolean"
+ Tcl_ObjType, since that type should now be rarely encountered.
+
+ * doc/BoolObj.3: Rewrite of documentation dropping many details
+ about the internals of Tcl_Objs. Shorter documentation focuses on the
+ function and use of the routines.
+
+ * generic/tclInt.h: Revision to the "boolean" Tcl_ObjType, so that
+ * generic/tclObj.c: only string values like "yes" and "false" are
+ * tests/obj.test: kept as the "boolean" Tcl_ObjType. The string
+ values "0" and "1" are kept as "int" Tcl_ObjType, which also produce
+ quick calls to Tcl_GetBooleanFromObj(). Since this internal change
+ means a Tcl_ConvertToType to a "boolean" Tcl_ObjType might not produce
+ a Tcl_Obj of type "boolean", the registration of the "boolean" type is
+ also removed.
+ ***POTENTIAL INCOMPATIBILITY***
+ For callers of Tcl_GetObjType on the type name "boolean".
+
+2005-05-17 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclObj.c (TclInitObjSubsystem): Removed the
+ * tests/listObj.test: registration of the Tcl_ObjType's "list",
+ * tests/obj.test: "procbody", "index", "ensembleCommand",
+ "localVarName", and "levelReference". The only reason to register a
+ Tcl_ObjType is to have it returned by Tcl_GetObjType, and the only
+ reason for that is to retrieve a (Tcl_ObjType *) to pass to
+ Tcl_ConvertToType(). None of the types above can support a
+ Tcl_ConvertToType() call; they panic. Better not to offer something
+ than to lead users into a panic.
+ ***POTENTIAL INCOMPATIBILITY***
+ For callers of Tcl_GetObjType on the type names listed above.
+
+2005-05-15 Kevin Kenny <kennykb@users.sourceforge.net>
+
+ * win/tclWin32Dll.c: conditioned definition of EXCEPTION_REGISTRATION
+ structures on HAVE_NO_SEH, to fix a bug in buildability on MSVC.
+
+2005-05-14 Daniel Steffen <das@users.sourceforge.net>
+
+ * generic/tclInt.decls:
+ * generic/tclTest.c:
+ * generic/tclUtil.c:
+ * win/tclWin32Dll.c: fixed link error due to direct access by tclTest.c
+ to the MODULE_SCOPE tclPlatform global: renamed existing
+ TclWinGetPlatform() accessor to TclGetPlatform() and moved it to
+ generic code so that it can be used by on all platforms where
+ MODULE_SCOPE is enforced.
+
+ * macosx/tclMacOSXBundle.c:
+ * unix/tclUnixInit.c:
+ * unix/tcl.m4 (Darwin): made use of CoreFoundation API configurable and
+ added test of CoreFoundation availablility to allow building on ppc64,
+ replaced HAVE_CFBUNDLE by HAVE_COREFOUNDATION; test for availability of
+ Tiger or later OSSpinLockLock API.
+
+ * unix/tclUnixNotfy.c:
+ * unix/Makefile.in:
+ * macosx/tclMacOSXNotify.c (new file): when CoreFoundation is
+ available, use new CFRunLoop based notifier: allows easy integration
+ with other event loops on Mac OS X, in particular the TkAqua Carbon
+ event loop is now integrated via a standard tcl event source (instead
+ of TkAqua upon loading having to finalize the exsting notifier and
+ replace it with its custom version). [Patch 1202052]
+
+ * tests/unixNotfy.test: don't run unthreaded tests on Darwin since
+ notifier may be using threads even in unthreaded core.
+
+ * unix/tclUnixPort.h:
+ * unix/tcl.m4 (Darwin): test for thread-unsafe realpath during
+ configure, as Darwin 7 and later realpath is threadsafe.
+
+ * macosx/Makefile: enable configure caching.
+
+ * unix/configure.in: wrap tclConfig.h header in #ifndef _TCLCONFIG so
+ that it can be included more than once without warnings from gcc4.0 (as
+ happens e.g. when including both tclInt.h and tclPort.h)
+
+ * macosx/tclMacOSXBundle.c:
+ * unix/tclUnixChan.c:
+ * unix/tclLoadDyld.c:
+ * unix/tclUnixInit.c: fixed gcc 4.0 warnings.

+ * generic/tclStubInit.c: make genstubs
+
+2005-05-13 Kevin Kenny <kennykb@acm.org>
+
+ * win/tclWin32Dll.c: Further rework of the SEH logic. All
+ EXCEPTION_REGISTRATION records are now in the activation record rather
+ than pushed on the stack.
+
+2005-05-13 Don Porter <dgp@users.sourceforge.net>
+
+ * generic/tclBasic.c: Dropped the TCL_NO_MATH configuration. It's
+ * generic/tclBinary.c: believed this has not been working in a long

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

+
+ * generic/tclStrToD.c (TclStrToD, RefineResult, ParseNaN): Changed the

+ silence complaints from the Solaris compiler.
+
+2005-05-10 Jeff Hobbs <jeffh@ActiveState.com>
+
+ * unix/tclUnixFCmd.c: add lint attr to enum to satisfy strictly

+
+ * tests/string.test: string-10.[21-30]
+ * generic/tclCmdMZ.c (Tcl_StringObjCmd): add extra checks to prevent

+
+2005-05-10 Kevin Kenny <kennykb@acm.org>
+
+ * generic/tclBinary.c (FormatNumber): Fixed a bug where NaN's resulted
+ in reads of uninitialized memory when using 'd', 'q', or 'Q' format.
+ * generic/tclStrToD.c (ParseNaN, TclFormatNaN): Added code to handle
+ the peculiarities of HP's PA_RISC, which uses a different 'quiet' bit
+ in NaN from everyone else.

+
+ [kennykb-numerics-branch]
+ * generic/tclStrToD.c: Made code more portable by finding a workaround
+ for MSVC's 'volatile' issue that does not require conditional
+ compilation.
+ * win/tclWin32Dll.c (TclWinCPUID): Removed structured event handling
+ from the GCC code since (a) bad code is generated by the instruction

+
+ The 2005-04-21 changes to Tcl_GetBooleanFromObj were done to bring it
+ into agreement with its docs. Further investigation reveals it was the
+ docs that were incorrect.
+
+ * doc/BoolObj.3: Corrections to the documentation of
+ Tcl_GetBooleanFromObj to bring it into agreement with what this public
+ interface has always done, including noting the difference in function
+ between Tcl_GetBooleanFromObj and Tcl_GetBoolean.
+
+ * generic/tclGet.c: Revised Tcl_GetBoolean to no longer be a
+ wrapper around Tcl_GetBooleanFromObj (different function!).
+
+ * generic/tclObj.c: Removed TclGetTruthValueFromObj routine that
+ was added yesterday. Revisions so that only Tcl_GetBoolean-approved
+ values get the "boolean" Tcl_ObjType. This retains the fix for [Bug
+ 1187123].

+
+ * doc/GetInt.3: Convert argument "string" to "str" to agree with code.
+ Also clarified a few details on int and double formats.
+ * generic/tclGet.c: Radical code simplification. Converted
+ Tcl_GetFoo() routines into wrappers around Tcl_GetFooFromObj(). Reduces
+ code duplication, and the resulting potential for inconsistency.
+
+ * generic/tclObj.c: Several changes:
+
+ - Re-ordered error detection code so all values with trailing garbage
+ receive a "not an integer" message instead of an "integer too large"
+ message.
+ - Removed inactive code meant to deal with strtoul* routines that fail
+ to parse leading signs. All of them do, and if any are detected that
+ do not, the correct fix is replacement with compat/strtoul*.c, not a
+ lot of special care by the callers.
+ - Tcl_GetDoubleFromObj now avoids shimmering away a "wideInt" intrep.
+ - Fixed Tcl_GetBooleanFromObj to agree with its documentation and with
+ Tcl_GetBoolean, accepting only "0" and "1" and not other numeric
+ strings. [Bug 1187123]
+ - Added new private routine TclGetTruthValueFromObj to perform the more
+ permissive conversion of numeric values to boolean that is needed by
+ the [expr] machinery.
+
+ * generic/tclInt.h (TclGetTruthValueFromObj): New routine.
+ * generic/tclExecute.c: Updated callers to call new routine.
+ * generic/tclBasic.c: Updated callers to call new routine.
+ * generic/tclCompCmds.c: Updated callers to call new routine.
+ * generic/tclDictObj.c: Updated callers to call new routine.
+ * tests/obj.test: Corrected bad tests that actually expected
+ values like "47" and "0xac" to be accepted as booleans.
+
+ * generic/tclLiteral.c: Disabled the code that forces some literals
+ into the "int" Tcl_ObjType during registration. We can re-enable it if
+ this change causes trouble, but it seems more sensible to let Tcl's
+ "on-demand" shimmering rule, and not try to pre-guess things.

+
+ * generic/tclEncoding.c: Several changes to the way the
+ encodingFileMap cache is maintained. Previously, it was attempted to

+ an expensive "glob" operation to fill the cache. Now the validity of

+ is permitted to fall out of sync with the encoding search path. Only
