present on the system.

2013-02-05  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclLoadNone.c (TclpLoadMemory): [Bug 3433012]: Added dummy
version of this function to use in the event that a platform thinks it
can load from memory but cannot actually do so due to it being
disabled at configuration time.

2013-01-30  Andreas Kupries  <andreask@activestate.com>

* library/platform/platform.tcl (::platform::LibcVersion): See
* library/platform/pkgIndex.tcl: [Bug 3599098]: Fixed the RE
* unix/Makefile.in: extracting the version to avoid issues with
* win/Makefile.in: recent changes to the glibc banner. Now
  targeting a less variable part of the string. Bumped package to
  version 1.0.11.

2013-01-26  Jan Nijtmans  <nijtmans@users.sf.net>

* unix/tclUnixCompat.c: [Bug 3601804]: platformCPUID segmentation
fault on Darwin.

2013-01-23  Donal K. Fellows  <dkf@users.sf.net>

* library/http/http.tcl (http::geturl): [Bug 2911139]: Do not do vwait

without a -command option). Internally, this means that all sockets
created by the http package will always be operated in asynchronous

2013-01-18  Jan Nijtmans  <nijtmans@users.sf.net>

* generic/tclPort.h: [Bug 3598300]: unix: tcl.h does not include

2013-01-16  Jan Nijtmans  <nijtmans@users.sf.net>

* Makefile.in: Enable win32 build with -DTCL_NO_DEPRECATED, just
* generic/tcl.h: as the UNIX build. Define Tcl_EvalObj and
* generic/tclDecls.h: Tcl_GlobalEvalObj as macros, even when
* generic/tclBasic.c: TCL_NO_DEPRECATED is defined, so Tk
can benefit from it too.

2013-01-14  Jan Nijtmans  <nijtmans@users.sf.net>

* win/tcl.m4: More flexible search for win32 tclConfig.sh,
backported from TEA (not actually used in Tcl, only for Tk)

2013-01-13  Jan Nijtmans  <nijtmans@users.sf.net>

* generic/tclIntDecls.h: If TCL_NO_DEPRECATED is defined, make

table, even if the inclusion is through tclInt.h.

2013-01-09  Jan Nijtmans  <nijtmans@users.sf.net>

* library/http/http.tcl: [Bug 3599395]: http assumes status line

called via junction without folder list access.

2013-01-07  Jan Nijtmans  <nijtmans@users.sf.net>

* generic/tcl.decls: Extend the public stub table with dummy NULL
entries, up to the size of the Tcl 8.6 stub tables. This makes it
easier to debug extensions which use Tcl 8.6 features but (erroneously)
are attempted to be loaded in Tcl 8.5.

2013-01-02  Miguel Sofer  <msofer@users.sf.net>

* generic/tclEnsemble.c:  Remove stray calls to Tcl_Alloc and
* generic/tclExecute.c:   friends: the core should only use ckalloc

* generic/tclTomMathInterface.c:

2012-12-31  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclListObj.c: [Bug 3598580]: Tcl_ListObjReplace may release
deleted elements too early

2012-12-21  Jan Nijtmans  <nijtmans@users.sf.net>

* unix/dltest/pkgb.c:  Make pkgb.so loadable in Tcl 8.4 as well.

isDigit() functions, just do the same inline.

2012-12-13  Jan Nijtmans  <nijtmans@users.sf.net>

* generic/tcl.h: Fix Tcl_DecrRefCount macro such that it
doesn't access its objPtr parameter twice any more.

2012-12-07  Jan Nijtmans  <nijtmans@users.sf.net>

* unix/dltest/pkgb.c:  Turn pkgb.so into a Tcl9 interoperability test
        library: Whatever Tcl9 looks like, loading pkgb.so in Tcl 9 should
        either result in an error-message, either succeed, but never crash.

2012-11-14  Donal K. Fellows  <dkf@users.sf.net>

* unix/tclUnixPipe.c (DefaultTempDir): [Bug 2933003]: Allow overriding
of the back-stop default temporary file location at compile time by
setting the TCL_TEMPORARY_FILE_DIRECTORY #def to a string containing
the directory name (defaults to "/tmp" as that is the most common

2012-11-13  Joe Mistachkin  <joe@mistachkin.com>

* win/tclWinInit.c: also search for the library directory (init.tcl,
encodings, etc) relative to the build directory associated with the
source checkout.

2012-11-09  Don Porter  <dgp@users.sourceforge.net>

2012-11-06  Donal K. Fellows  <dkf@users.sf.net>

* library/http/http.tcl (http::Finish): [Bug 3581754]: Ensure that
callbacks are done at most once to prevent problems with timeouts on a
keep-alive connection (combined with reentrant http package use)
causing excessive stack growth. Not a fix for the underlying problem,
but ensures that pain will be mostly kept away from users.
Bump http package to 2.7.10.

* generic/tclEvent.c: [Bug 3576509]: tcl::Bgerror crashes with invalid

2012-10-03  Don Porter  <dgp@users.sourceforge.net>

compare the channel state, not the channel itself so that stacked
channels do not cause trouble.

scheme outlined on http://www.opengroup.org/austin/docs/austin_328.txt
to handle Tcl's use of standard reentrant versions of the passwd/group
access functions so that everything can work on all BSDs. Problem
identified by Stuart Cassoff.

2012-07-11  Jan Nijtmans  <nijtmans@users.sf.net>

* win/tclWinReg.c: [Bug #3362446]: registry keys command fails

problems when using HKEY_PERFORMANCE_DATA.

2012-07-10  Jan Nijtmans  <nijtmans@users.sf.net>

2012-07-10  Donal K. Fellows  <dkf@users.sf.net>

* win/tclWinSock.c (InitializeHostName): Corrected logic that
extracted the name of the computer from the gethostname call so that

2012-06-29  Donal K. Fellows  <dkf@users.sf.net>

* doc/GetIndex.3: Reinforced the description of the requirement for
the tables of names to index over to be static, following posting to
tcl-core by Brian Griffin about a bug caused by Tktreectrl not obeying
this rule correctly. This does not represent a functionality change,
merely a clearer documentation of a long-standing constraint.

2012-06-25  Don Porter  <dgp@users.sourceforge.net>

* generic/tclFileSystem.h: [Bug 3024359]: Make sure that the
* generic/tclIOUtil.c: per-thread cache of the list of file systems
* generic/tclPathObj.c: currently registered is only updated at times
when no active loops are traversing it.  Also reduce the amount of
epoch storing and checking to where it can make a difference.

2012-06-25  Donal K. Fellows  <dkf@users.sf.net>

systems that need inclusion in all compilation units are supported.

2012-06-06  Jan Nijtmans  <nijtmans@users.sf.net>

* unix/tclUnixInit.c: On Cygwin, use win32 API in stead of uname()
to determine the tcl_platform variables.

2012-05-31  Donal K. Fellows  <dkf@users.sf.net>

* doc/safe.n: [Bug 1997845]: Corrected formatting so that generated

2012-05-29  Donal K. Fellows  <dkf@users.sf.net>

* doc/expr.n, doc/mathop.n: [Bug 2931407]: Clarified semantics of

going on with respect to qualification of command prefixes in ensemble
subcommand maps.

2012-05-25  Jan Nijtmans  <nijtmans@users.sf.net>

* win/tclWinDde.c: [Bug 473946]: special characters not correctly

XTYP_REQUEST.  Fix "make genstubs" when cross-compiling on UNIX

2012-05-24  Jan Nijtmans  <nijtmans@users.sf.net>

* tools/genStubs.tcl:  Take cygwin handling of X11 into account.
* generic/tcl*Decls.h: re-generated
* generic/tclStubInit.c:  Implement TclpIsAtty, Cygwin only.
* doc/dde.n: Doc fix: "dde execute iexplore" doesn't work
without -async, because iexplore doesn't return a value

2012-05-22  Jan Nijtmans  <nijtmans@users.sf.net>

* tools/genStubs.tcl:   Let cygwin share stub table with win32
* win/Makefile.in:      Don't hardcode dde and reg dll version numbers
* win/tclWinSock.c:     implement TclpInetNtoa for win32
* generic/tclInt.decls: Revert most of [fcc5957e59], since when
  we let cygwin share the win32 stub table this is no longer necessary
* generic/tcl*Decls.h:  re-generated

2012-05-21  Don Porter  <dgp@users.sourceforge.net>

* generic/tclFileName.c: When using Tcl_SetObjLength() calls to grow
* generic/tclIOUtil.c: and shrink the objPtr->bytes buffer, care must
be taken that the value cannot possibly become pure Unicode.  Calling
Tcl_AppendToObj() has the possibility of making such a conversion.  Bug
found while valgrinding the trunk.

2012-05-17  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): [Bug 3106532]: Corrected
resulting indexes from -indexvar option to be usable with [string
range]; this was always the intention (and is consistent with [regexp
-indices] too).
Uses of [switch -regexp -indexvar] that previously compensated for the
wrong offsets (by subtracting 1 from the end indices) now do not need
to do so as the value is correct.

* library/safe.tcl (safe::InterpInit): Ensure that the module path is
constructed in the correct order.
(safe::AliasGlob): [Bug 2964715]: More extensive handling of what
globbing is required to support package loading.

* doc/expr.n: [Bug 3525462]: Corrected statement about what happens
when comparing "0y" and "0x12"; the previously documented behavior was
actually a subtle bug (now long-corrected).

2012-05-13  Jan Nijtmans  <nijtmans@users.sf.net>

* win/tclWinDde.c: Protect against receiving strings without
ending \0, as external applications (or Tcl with TIP #106) could
generate that.

* generic/tclCompile.c (TclFixupForwardJump): Tracked down and fixed
* generic/tclBasic.c (TclArgumentBCEnter): the cause of a violation
of my assertion that 'ePtr->nline == objc' in TclArgumentBCEnter.
When a bytecode was grown during jump fixup the pc -> command line

would direct command A to the data for command B, with a different
number of arguments.

2011-05-10  Don Porter  <dgp@users.sourceforge.net>

* generic/tclInt.h:     New internal routines TclScanElement() and
* generic/tclUtil.c:    TclConvertElement() are rewritten guts of
machinery to produce string rep of lists.  The new routines avoid
and correct [Bug 3173086].  See comments for much more detail.

* generic/tclDictObj.c:         Update all callers.
* generic/tclIndexObj.c:
* generic/tclListObj.c:
* generic/tclUtil.c:

* generic/tclUtil.c: Tighten Tcl_SplitList().
* generic/tclListObj.c: Tighten SetListFromAny().
* generic/tclDictObj.c: Tighten SetDictFromAny().

2011-05-02  Don Porter  <dgp@users.sourceforge.net>

* generic/tclCmdMZ.c: Revised TclFindElement() interface.  The
* generic/tclDictObj.c: final argument had been bracePtr, the address
* generic/tclListObj.c: of a boolean var, where the caller can be told
* generic/tclParse.c: whether or not the parsed list element was
* generic/tclUtil.c: enclosed in braces.  In practice, no callers
really care about that.  What the callers really want to know is
whether the list element value exists as a literal substring of the
string being parsed, or whether a call to TclCopyAndCollpase() is
needed to produce the list element value.  Now the final argument
is changed to do what callers actually need.  This is a better fit
for the calls in tclParse.c, where now a good deal of post-processing
checking for "naked backslashes" is no longer necessary.
For any callers calling in via the internal stubs table who really
do use the final argument explicitly to check for the enclosing brace
scenario.  Simply looking for the braces where they must be is the
revision available to those callers, and it will backport cleanly.

* tests/parse.test: Tests for expanded literals quoting detection.

* generic/tclCompCmds.c: New TclFindElement() is also a better
fit for the [switch] compiler.

* generic/tclInt.h: Replace TclCountSpaceRuns() with
* generic/tclListObj.c: TclMaxListLength() which is the function we
* generic/tclUtil.c: actually want.
* generic/tclCompCmds.c:

* generic/tclCompCmds.c: Rewrite of parts of the switch compiler to
better use the powers of TclFindElement() and do less parsing on
its own.

2011-04-28  Don Porter  <dgp@users.sourceforge.net>

* generic/tclInt.h: New utility routines:
* generic/tclParse.c: TclIsSpaceProc() and

2011-04-20  Andreas Kupries  <andreask@activestate.com>

* generic/tclFCmd.c (TclFileAttrsCmd): Added commands to reset the
typePtr of the Tcl_Obj* whose int-rep was just purged. Required to
prevent a dangling IndexRep* to reused, smashing the heap. See
also the entries at 2011-04-16 and 2011-03-24 for the history of
the problem.

* generic/tclFCmd.c (TclFileAttrsCmd): Tidied up the memory management
a bit to try to ensure that the dynamic and static cases don't get
confused while still promoting caching where possible. Added a panic
to trap problems in the case where an extension is misusing the API.

2011-04-13  Don Porter  <dgp@users.sourceforge.net>

* generic/tclUtil.c: [Bug 3285375]: Rewrite of Tcl_Concat*()
routines to prevent segfaults on buffer overflow.  Build them out of
existing primitives already coded to handle overflow properly.  Uses
the new TclTrim*() routines.

* unix/Makefile.in:
* win/Makefile.in:
* win/makefile.vc: Rewrite of Tcl_PrintDouble and TclDoubleDigits
that (a) fixes a severe performance problem with floating point
shimmering reported by Karl Lehenbauer, (b) allows TclDoubleDigits
to generate the digit strings for 'e' and 'f' format, so that it
can be used for tcl_precision != 0 (and possibly later for [format]),
(c) fixes [Bug 3120139] by making TclPrintDouble inherently
locale-independent, (d) adds test cases to util.test for
correct rounding in difficult cases of TclDoubleDigits where fixed-
precision results are requested. (e) adds test cases to util.test for
the controversial aspects of [Bug 3105247]. As a side effect, two
more modules from libtommath (bn_mp_set_int.c and bn_mp_init_set_int.c)
are brought into the build, since the new code uses them.

* generic/tclIntDecls.h:

* generic/tclCompCmds.c (TclCompileCatchCmd):
* tests/compile.test (compile-3.6): [Bug 3098302]: Reworked the
compilation of the [catch] command so as to avoid placing any code
that might throw an exception (specifically, any initial substitutions
or any stores to result or options variables) between the BEGIN_CATCH
and END_CATCH but outside the exception range.  Added a test case that
panics on a stack smash if the change is not made.

2010-11-01  Stuart Cassoff  <stwo@users.sourceforge.net>

2010-10-01  Jeff Hobbs  <jeffh@ActiveState.com>

return data to interp by default, or if given an arg, use that as
filename to output to (accepts 'stdout' and 'stderr').
Fix output to print used inst count data.

documentation on how the module works to the top.

2010-09-23  Don Porter  <dgp@users.sourceforge.net>

pure, but more useful.

2010-09-08  Andreas Kupries  <andreask@activestate.com>

*** 8.5.9 TAGGED FOR RELEASE ***

* doc/tm.n: Added underscore to the set of characters accepted in

2010-09-06  Stuart Cassoff  <stwo@users.sourceforge.net>

* unix/configure.in, generic/tclIOUtil.c (Tcl_Stat): Updated so that
we do not assume that all unix systems have the POSIX blkcnt_t type,
since OpenBSD apparently does not. Backported from HEAD (2010-02-16).
* unix/configure: autoconf-2.59

2010-09-02  Andreas Kupries  <andreask@activestate.com>

* doc/glob.n: Fixed documentation ambiguity regarding the handling
of -join.

* library/safe.tcl (::safe::AliasGlob): Fixed another problem, the
option -join does not stop option processing in the core builtin,
so the emulation must not do that either.

2010-09-01  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

* library/safe.tcl (::safe::AliasGlob): Moved the command
extending the actual glob command with a -directory flag to when
we actually have a proper untranslated path,

2010-09-01  Don Porter  <dgp@users.sourceforge.net>

* changes: Update for 8.5.9 release.

2010-09-01  Andreas Kupries  <andreask@activestate.com>

showing the difference.

2010-09-01  Donal K. Fellows  <dkf@users.sf.net>

* win/configure, win/configure.in, win/tcl.m4: SC_EMBED_MANIFEST
macro and --enable-embedded-manifest configure arg added to
support manifest embedding where we know the magic.  Help prevents
DLL hell with MSVC8+.

* generic/tclTrace.c (TraceExecutionObjCmd, TraceCommandObjCmd)
(TraceVariableObjCmd): [Patch 3048354]: Use memcpy() instead of
strcpy() to avoid buffer overflow; we have the correct length of data
to copy anyway since we've just allocated the target buffer.

2010-08-15  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclProc.c (ProcWrongNumArgs): [Bug 3045010]: Make the

less verbose when a lambda term is present.

that went with it.  Remove pre-4 AIX build support.

null-terminated, so account for that.

the local hashtable deletion crash and fix.

* tests/info.test (info-39.1, test_info_frame): Changed absolute to
relative frame adressing to handle difference between testing with
-singleproc 1 vs. the default -singleproc 0. Plus comment fix. The
test and issue are not relevant to the trunk, forward porting is not

* generic/tclIO.c (CreateScriptRecord): [Bug 2918110]: Initialize
the EventScriptRecord (esPtr) fully before handing it to
Tcl_CreateChannelHandler for registration. Otherwise a reflected
channel calling 'chan postevent' (== Tcl_NotifyChannel) in its
'watchProc' will cause the function 'TclChannelEventScriptInvoker'
to be run on an uninitialized structure.

comments to describe when the function can be entered for the same
Tcl_Obj* multiple times. This is a continuation of the 2009-11-10
entry where a memory leak was plugged, but where not sure if that was
just a band-aid to paper over some other error. It isn't, this is a
legal situation.

the expected number of arguments when generating an error for round().

2009-10-29  Don Porter  <dgp@users.sourceforge.net>

* generic/tcl.h: [Bug 2800740]: Changed the typedef for the
mp_digit type from:
typedef unsigned long mp_digit;
typedef unsigned int mp_digit;
For 32-bit builds where "long" and "int" are two names for the same
thing, this is no change at all. For 64-bit builds, though, this
causes the dp[] array of an mp_int to be made up of 32-bit elements
instead of 64-bit elements. This is a huge improvement because details
elsewhere in the mp_int implementation cause only 28 bits of each
element to be actually used storing number data. Without this change
bignums are over 50% wasted space on 64-bit systems.

For 64-bit builds, callers of routines with (mp_digit) or (mp_digit *)
arguments *will*, and callers of routines with (mp_int *) arguments
*may* suffer both binary and stubs incompatibilities with Tcl releases
8.5.0 - 8.5.7.  Such possibilities should be checked, and if such
incompatibilities are present, suitable [package require] requirements
on the Tcl release should be put in place to keep such built code
[load]-ing only in Tcl interps that are compatible.

* library/clock.tcl (LocalizeFormat):

* generic/tclIO.c (FlushChannel): Skip OutputProc for low-level
0-length writes. When closing pipes which have already been closed not
skipping leads to spurious SIG_PIPE signals. Reported by Mikhail
Teterin <mi+thun@aldan.algebra.com>.

2009-10-19  Don Porter  <dgp@users.sourceforge.net>

* generic/tclIO.c: Revised ReadChars and FilterInputBytes
routines to permit reads to continue up to the string limits of Tcl

little as half the limiting value length was reached. [Patch 2107634]
Thanks to Sean Morrison and Bob Parker for their roles in the fix.

2009-10-18  Joe Mistachkin  <joe@mistachkin.com>

* tests/thread.test (thread-4.[345]): [Bug 1565466]: Correct tests to
save their error state before the final call to threadReap just in
case it triggers an "invalid thread id" error.  This error can occur
if one or more of the target threads has exited prior to the attempt
to send it an asynchronous exit command.

* generic/tclPathObj.c: [Bug 2806250]: Prevent the storage of strings

* generic/tclCmdMZ.c (StringIsCmd): Reorganize so that [string is] is
more efficient when parsing things that are correct, at a cost of
making the empty string test slightly more costly. With this, the cost
of doing [string is integer -strict $x] matches [catch {expr {$x+0}}]
in the successful case, and greatly outstrips it in the failing case.

* tests/info.test (info-39.0):

Backport of some changes made to the Tcl head, to handle literal
sharing better. The code here is much simpler (trimmed down) compared
to the head as the 8.5 branch is not bytecode compiling whole files,
and doesn't compile eval'd code either.

Reworked the handling of literal command arguments in bytecode to be
saved (compiler) and used (execution) per command (see the
TCL_INVOKE_STK* instructions), and not per the whole bytecode.  This
removes the problems with location data caused by literal sharing in
proc bodies. Simplified the associated datastructures (ExtIndex is
gone, as is the function EnterCmdWordIndex).

* win/tclWinInit.c:  fixes a problem obtaining the username when the
USERNAME environment variable is unset.

* generic/tclStringObj.c: sprintf() -> Tcl_ObjPrintf() conversion.

* generic/tclCompile.c: The value stashed in iPtr->compiledProcPtr
* generic/tclProc.c: when compiling a proc survives too long.  We
* tests/execute.test: only need it there long enough for the right
TclInitCompileEnv() call to re-stash it into envPtr->procPtr.  Once
that is done, the CompileEnv controls.  If we let the value of
iPtr->compiledProcPtr linger, though, then any other bytecode compile
operation that takes place will also have its CompileEnv initialized
with it, and that's not correct.  The value is meant to control the
compile of the proc body only, not other compile tasks that happen
along.  Thanks to Carlos Tasada for discovering and reporting the
problem.  [Bug 2802881].

2009-06-10  Don Porter  <dgp@users.sourceforge.net>

* generic/tclStringObj.c: Revised [format] to not overflow the
integer calculations computing the length of the %ll formats of
really big integers.  Also added protections so that [format]s that
would produce results overflowing the maximum string length of Tcl
values throw a normal Tcl error instead of a panic. [Bug 2801413]

2006-06-09  Kevin B. Kenny  <kennykb@acm.org>

* generic/tclGetDate.y: Fixed a thread safety bug in the generated
* library/clock.tcl:    Bison parser (needed a %pure-parser
* tests/clock.test:     declaration to avoid static variables).
Discovered that the %pure-parser declaration
                        allowed for returning the Bison error message
                        to the Tcl caller in the event of a syntax
                        error, so did so.
* generic/tclDate.c: bison 2.3

different when rendered through groff or as HTML, but it was still
wrong both ways.)

command and added tests to the test suite.  [Bug 2603158]

2009-03-27  Don Porter  <dgp@users.sourceforge.net>

* generic/tclPathObj.c (TclPathPart): TclPathPart() was computing
* tests/fileName.test: the wrong results for both [file dirname] and
[file tail] on "path" arguments with the PATHFLAGS != 0 intrep and
with an empty string for the "joined-on" part.  [Bug 2710920]

2009-03-20  Don Porter  <dgp@users.sourceforge.net>

* generic/tclStringObj.c:       Test stringObj-6.9 checks that

Added support for SIGINFO, which is present on BSD platforms.

2009-02-20  Don Porter  <dgp@users.sourceforge.net>

* generic/tclPathObj.c: Fixed mistaken logic in TclFSGetPathType()
* tests/fileName.test:  that assumed (not "absolute" => "relative").
This is a false assumption on Windows, where "volumerelative" is
another possibility.  [Bug 2571597].

2009-02-17  Jeff Hobbs  <jeffh@ActiveState.com>

* win/tcl.m4, win/configure: Check if cl groks _WIN64 already to

* generic/tclIORChan.c (ReflectClose): Fix for [Bug 2458202].
Closing a channel may supply NULL for the 'interp'. Test for
finalization needs to be different, and one place has to pull the
interp out of the channel instead.

2009-01-19  Kevin B. Kenny  <kennykb@acm.org>

* unix/Makefile.in: Added a CONFIG_INSTALL_DIR parameter so that
* unix/tcl.m4:      distributors can control where tclConfig.sh goes.

[Patch 2114900] thanks to Stu Cassoff <stwo@users.sf.net>
Backport of 2008-11-26 commit from Kevin Kenny.

* win/tclWinThrd.c (TclpThreadCreate): We need to initialize the
thread id variable to 0 as on 64 bit windows this is a pointer sized
field while windows only fills it with a 32 bit value. The result is
an inability to join the threads as the ids cannot be matched.
Backport of 2008-10-13 commit from Pat Thoyts.

* generic/tclIO.c (SetChannelFromAny and related): Modified the
* tests/io.test: internal representation of the tclChannelType to
contain not only the ChannelState pointer, but also a reference to the

complete normalization attention for correct results. [Bug 2385549]

2008-12-03  Don Porter  <dgp@users.sourceforge.net>

* generic/tclFileName.c (DoGlob): One of the Tcl_FSMatchInDirectory
calls did not have its return code checked. This caused error messages
returned by some Tcl_Filesystem drivers to be swallowed.

2008-12-02  Andreas Kupries  <andreask@activestate.com>

* generic/tclTest.c (TestconcatobjCmd): fix use of internal-only
TclInvalidateStringRep macro.
[Bug 2057479]

2008-08-17  Miguel Sofer  <msofer@users.sf.net>

* generic/tclTest.c (TestconcatobjCmd):
* generic/tclUtil.c (Tcl_ConcatObj):
* tests/util.test (util-4.7):
fix [Bug 1447328]; the original "fix" turned Tcl_ConcatObj() into
a hairy monster. This was exposed by [Bug 2055782]. Additionally,
Tcl_ConcatObj could corrupt its input under certain conditions!


2008-08-14  Don Porter  <dgp@users.sourceforge.net>

*** 8.5.4 TAGGED FOR RELEASE ***

* tests/fileName.test:  Revise new tests for portability to case
insensitive filesystems.

2008-08-14  Daniel Steffen  <das@users.sourceforge.net>

* generic/tclCompile.h: Add support for debug logging of DTrace
* generic/tclBasic.c: 'proc', 'cmd' and 'inst' probes (does
_not_ require a platform with DTrace).

* generic/tclCmdIL.c (TclInfoFrame): Check fPtr->line before
dereferencing as line info may
not exists when TclInfoFrame()
is called from a DTrace probe.

* tests/msgcat.test: Fix for ::tcl::mac::locale with
@modifier (HEAD backport 2008-06-01).

* tests/fCmd.test (fCmd-6.23): Made result matching robust when test
workdir and /tmp are not on same FS.

* unix/Makefile.in: Ensure Makefile shell is /bin/bash for
* unix/configure.in (SunOS): DTrace-enabled build on Solaris.
(followup to 2008-06-12) [Bug 2016584]

* unix/tcl.m4 (SC_PATH_X): Check for libX11.dylib in addition to
libX11.so et al.

* unix/configure: autoconf-2.59

2008-08-13  Don Porter  <dgp@users.sourceforge.net>

* library/http/http.tcl: Remove 8.5 requirement.
* library/http/pkgIndex.tcl:
* unix/Makefile.in:
* win/Makefile.in:
* win/makefile.vc:

2008-08-11  Andreas Kupries  <andreask@activestate.com>

* library/tm.tcl: Added a 'package provide' command to the generated
ifneeded scripts of Tcl Modules, for early detection of conflicts
between the version specified through the file name and a 'provide'
command in the module implementation, if any. Note that this change
also now allows Tcl Modules to not provide a 'provide' command at all,
and declaring their version only through their filename.

* generic/tclProc.c (Tcl_ProcObjCmd): Fixed memory leak triggered
* tests/proc.test: by procbody::test::proc. See [Bug 2043636]. Added a
test case demonstrating the leak before the fix. Fixed a few spelling
errors in test descriptions as well.

2008-08-11  Don Porter  <dgp@users.sourceforge.net>

* library/http/http.tcl: Bump http version to 2.7.1 to account
* library/http/pkgIndex.tcl: for [Bug 2046486] bug fix.  This
* unix/Makefile.in: release of http now requires a
* win/Makefile.in: dependency on Tcl 8.5 to be able to

locals in the localCache from the CallFrame and not from the Proc
which may have been mangled by a (broken?) recompile. Backport from
the HEAD.

2008-08-04  Don Porter  <dgp@users.sourceforge.net>

fallback to direct evaluation of commands in a compiled script.
[Bug 2037338]

* generic/tclExecute.c:  fix [Bug 2030670] that cause
TclStackRealloc to panic on rare corner cases. Thx ajpasadyn for
diagnose and patch.

2008-07-28  Andreas Kupries  <andreask@activestate.com>

* generic/tclBasic.c: Added missing ref count when creating an empty
string as path (TclEvalEx). In 8.4 the missing code caused panics in
the testsuite. It doesn't in 8.5. I am guessing that the code path
with the missing the incr-refcount is not invoked any longer. Because
the bug in itself is certainly the same.

2008-07-25  Daniel Steffen  <das@users.sourceforge.net>

* tests/info.test (info-37.0): Add !singleTestInterp constraint;
(info-22.8, info-23.0): switch to glob matching to avoid sensitivity
to tcltest.tcl line number changes, remove knownBug constraint, fix
expected result. [Bug 1605269]

2008-07-25  Andreas Kupries  <andreask@activestate.com>

* tests/info.test: Tests 38.* added, exactly testing the tracking of
location for uplevel scripts.

* generic/tclCompile.c (TclInitCompileEnv): Reorganized the
initialization of the #280 location information to match the flow in
TclEvalObjEx to get more absolute contexts.

* generic/tclBasic.c (TclEvalObjEx): Moved the pure-list optimization
out of the eval-direct code path to be done always, i.e. even when a
compile is requested. This way we do not loose the association between
#280 location information and the list elements, if any.

2008-07-23  Andreas Kupries  <andreask@activestate.com>

* tests/info.test: Reordered the tests to have monotonously
increasing numbers.

* generic/tclBasic.c: Modified TclArgumentGet to reject pure lists
* generic/tclCmdIL.c: immediately, without search. Reworked setup
* generic/tclCompile.c: of eoFramePtr, doesn't need the line
* tests/info.test: information, more sensible to have everything on
line 1 when eval'ing a pure list. Updated the users of the line
information to special case this based on the frame type (i.e.
TCL_LOCATION_EVAL_LIST). Added a testcase demonstrating the new

2008-07-22  Andreas Kupries  <andreask@activestate.com>

* generic/tclBasic.c: Added missing function comments.

* generic/tclCompile.c: Made the new TclEnterCmdWordIndex
* generic/tclCompile.h: static, and ansified.

* generic/tclBasic.c: Reworked the handling of bytecode literals
* generic/tclCompile.c: for #280 to fix the abysmal performance
* generic/tclCompile.h: for deep recursion, replaced the linear
* generic/tclExecute.c: search through the whole stack with another
* generic/tclInt.h: hashtable and simplified the data structure used
by the compiler (array instead of hashtable). Incidentially this also
fixes the memory leak reported via [Bug 2024937].

2008-07-21  Don Porter  <dgp@users.sourceforge.net>

* tests/encoding.test:  Make failing tests pass again. [Bug 1972867]

2008-07-21  Andreas Kupries <andreask@activestate.com>

* generic/tclBasic.c: Extended the existing TIP #280 system (info
* generic/tclCmdAH.c: frame), added the ability to track the
* generic/tclCompCmds.c: absolute location of literal procedure
* generic/tclCompile.c: arguments, and making this information
* generic/tclCompile.h: available to uplevel, eval, and
* generic/tclInterp.c: siblings. This allows proper tracking of

2008-07-20  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

* generic/tclDictObj.c (SetDictFromAny): Make the list->dict
transformation a bit more efficient; modern dicts are ordered and so
we can round-trip through lists without needing the string rep at all.
* generic/tclListObj.c (SetListFromAny): Make the dict->list
transformation not lossy of internal representations and hence more
efficient. [Bug 2008248] (ajpasadyn) but using a more efficient patch.

2008-07-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

* doc/DictObj.3: Fix error in example. [Bug 2016740]

* generic/tclGet.c: Corrected out of date comments.

2008-07-07  Andreas Kupries  <andreask@activestate.com>

interp result found by Don Porter.

* doc/regexp.n, doc/regsub.n: Correct examples. [Bug 1982642]

2008-07-04  Joe English  <jenglish@users.sourceforge.net>

* generic/tclEncoding.c(UtfToUtfProc): Avoid unwanted sign extension
when converting incomplete UTF-8 sequences. See [Bug 1908443] for

2008-07-03  Andreas Kupries  <andreask@activestate.com>

* generic/tclIORChan.c (InvokeTclMethod): Fixed the memory leak
reported in [Bug 1987821]. Thanks to Miguel for the rpeort and Don
Porter for tracking the cause down.

2008-07-03  Don Porter  <dgp@users.sourceforge.net>

* library/package.tcl:  Removed [file readable] testing from
[tclPkgUnknown] and friends. We find out soon enough whether a file is
readable when we try to [source] it, and not testing before allows us
to workaround the bugs on some common filesystems where [file
readable] lies to us. [Patch 1969717]

* unix/Makefile.in: Followup to my change of 2008-06-25, make code
generated by the Makefile and put into the installd tm.tcl conditional
on interpreter safeness as well. Thanks to Daniel Steffen for
reminding me of that code.

2008-06-25  Don Porter  <dgp@users.sourceforge.net>

* win/rules.vc:    Backported fix for dde/registry versions and
* win/makefile.vc: the staticpkg build option

2008-06-24  Don Porter  <dgp@users.sourceforge.net>

* generic/tclPathObj.c: Fixed some internals management in the "path"
Tcl_ObjType for the empty string value. Problem led to a crash in the
command [glob -dir {} a]. [Bug 1999176].

2008-06-23  Don Porter  <dgp@users.sourceforge.net>

* generic/tclPathObj.c: Fixed bug in Tcl_GetTranslatedPath() when
operating on the "Special path" variant of the "path" Tcl_ObjType
intrep. A full normalization was getting done, in particular, coercing
relative paths to absolute, contrary to what the function of
producing the "translated path" is supposed to do. [Bug 1972879]

* generic/tclClock.c (ClockConvertlocaltoutcObjCmd): Removed left
over debug output.

2008-06-17  Andreas Kupries  <andreask@activestate.com>

* doc/tm.n: Followup to changelog entry 2008-03-18 regarding
::tcl::tm::Defaults. Updated the documentation to not only mention
the new (underscored) form of environment variable names, but make
it the encouraged form as well. See [Bug 1914604].

2008-06-17  Kevin Kenny  <kennykb@acm.org>

* generic/tclClock.c (ConvertLocalToUTC):
* tests/clock.test (clock-63.1): Fixed a bug where the
internal ConvertLocalToUTC command segfaulted if passed a
dictionary without the 'localSeconds' key.  To the best of
my knowledge, the bug was not observable in the [clock]
command itself.

2008-06-16  Andreas Kupries  <andreask@activestate.com>

* generic/tclCmdIL.c (TclInfoFrame): Backport of fix made on the
* tests/info.test: head branch :: Moved the code looking up the
information for key 'proc' out of the TCL_LOCATION_BC branch to
after the switch, this is common to all frame types. Updated the
testsuite to match. This was exposed by the 2008-06-08 commit
(Miguel), switching uplevel from direct eval to compilation. Fixes
[Bug 1987851].

2008-06-12  Daniel Steffen  <das@users.sourceforge.net>

* unix/Makefile.in: add complete deps on tclDTrace.h.

* unix/Makefile.in: clean generated tclDTrace.h file.

* unix/tcl.m4 (SunOS-5.11): fix 64bit amd64 support with gcc & Sun cc.
* unix/configure: autoconf-2.59

* macosx/Tcl.xcodeproj/project.pbxproj: add debug configs with gcov,
and with corefoundation disabled; updates and cleanup for Xcode 3.1 and
for Leopard.
* macosx/Tcl.xcode/project.pbxproj: sync Tcl.xcodeproj changes.
* macosx/README: document new build configs.

2008-05-26  Jeff Hobbs  <jeffh@ActiveState.com>

* tests/io.test (io-53.9): need to close chan before removing file.

2008-05-23  Andreas Kupries  <andreask@activestate.com>

* win/tclWinChan.c (FileWideSeekProc): Accepted a patch by
Alexandre Ferrieux <ferrieux@users.sourceforge.net> to fix the
[Bug 1965787]. 'tell' now works for locations > 2 GB as well
instead of going negative.

* generic/tclIO.c (Tcl_SetChannelBufferSize): Accepted a patch by
* tests/io.test: Alexandre Ferrieux <ferrieux@users.sourceforge.net>
* tests/chanio.test: to fix the [Bug 1969953]. Buffersize outside
of the supported range are now clipped to nearest boundary instead
of ignored.

2008-05-22  Don Porter  <dgp@users.sourceforge.net>

* generic/tclNamesp.c (Tcl_LogCommandInfo): Restored ability to
handle the argument value length = -1.  Thanks to Chris Darroch for
discovering the bug and providing the fix.  [Bug 1968245].

2008-05-21  Don Porter  <dgp@users.sourceforge.net>

* generic/tclParse.c (ParseComment):    The new TclParseAllWhiteSpace
* tests/parse.test (parse-15.60):       routine has no mechanism to
return the "incomplete" status of "\\\n" so calling this routine
anywhere that can be reached within a Tcl_ParseCommand call is a
mistake. In particular, ParseComment must not use it. [Bug 1968882]

2008-05-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

* generic/tclNamesp.c (Tcl_SetNamespaceUnknownHandler): Corrected odd
logic for handling installation of namespace unknown handlers which
could lead too very strange things happening in the error case.

2008-05-16  Miguel Sofer  <msofer@users.sf.net>

* generic/tclCompile.c: Fix crash with tcl_traceExec. Found and
fixed by Alexander Pasadyn [Bug 1964803].

2008-05-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

* generic/tclCompCmds.c (TclCompileDictAppendCmd): Fix silly
off-by-one error that caused a crash every time a compiled 'dict
append' with more than one value argument was used. Found by Colin

2008-04-26  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

* generic/tclAsync.c: Tcl_AsyncDelete(): panic if attempt to locate
handler token fails. Happens when some other thread attempts to delete
somebody else's token.

Also, panic early if we find out the wrong thread attempting to delete
the async handler (common trap). As, only the one that created the
handler is allowed to delete it.

2008-04-24  Andreas Kupries  <andreask@activestate.com>

* tests/ioCmd.test: Extended testsuite for reflected channel
implementation. Added test cases about how it handles if the rug is
pulled out from under a channel (= killing threads, interpreters
containing the tcl command for a channel, and channel sitting in a
different interpreter/thread.)

* generic/tclIORChan.c: Fixed the bugs exposed by the new testcases,
redone most of the cleanup and exit handling.

2008-04-15  Andreas Kupries  <andreask@activestate.com>

* generic/tclIO.c (CopyData): Applied another patch by Alexandre
* io.test (io-53.8a): Ferrieux <ferrieux@users.sourceforge.net>,
* chanio.test (chan-io-53.8a): to shift EOF handling to the async
part of the command if a callback is specified, should the channel
be at EOF already when fcopy is called. Testcase by myself.

2008-04-14  Kevin B. Kenny <kennykb@acm.org>

* unix/tclUnixTime.c (NativeGetTime): Removed obsolete use of
'struct timezone' in the call to 'gettimeofday'. [Bug 1942197].
* tests/clock.test (clock-33.5, clock-33.5a, clock-33.8, clock-33.8a):
Added comments to the test that it can fail on a heavily loaded

2008-04-11  Don Porter <dgp@users.sourceforge.net>

2008-04-10  Andreas Kupries  <andreask@activestate.com>

* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Keeping check for negative
values, changed to not be an error, but behave like the special
value -1 (copy all, default).

* tests/iocmd.test (iocmd-15.{12,13}): Removed.

* tests/io.test (io-52.5{,a,b}): Reverted last change, added
* tests/chanio.test (chan-io-52.5{,a,b}): comment regarding the
meaning of -1, added two more testcases for other negative values,
and input wrapped to negative.

2008-04-09  Andreas Kupries  <andreask@activestate.com>

* tests/chanio.test (chan-io-52.5): Removed '-size -1' from test,
* tests/io.test (io-52.5): does not seem to have any bearing, and
  was an illegal value.

* generic/tclIOCmd.c (Tcl_FcopyObjCmd): Added checking of -size
* tests/ioCmd.test (iocmd-15.{13,14}): value to reject negative
values, and values overflowing 32-bit signed. [Bug 1557855]. Basic
patch by Alexandre Ferrieux <ferrieux@users.sourceforge.net>, with
modifications from me to separate overflow from true negative
value. Extended testsuite.

2008-04-08  Andreas Kupries  <andreask@activestate.com>

* tests/io.test (io-53.8): Fixed ordering of vwait and after
cancel. cancel has to be done after the vwait completes.

2008-04-09  Daniel Steffen  <das@users.sourceforge.net>

* tests/chanio.test (chan-io-53.8,53.9,53.10): fix typo & quoting for

* tests/chanio.test:
* generic/tclIO.c: Additional changes to data structures for fcopy
* generic/tclIO.h: and channels to perform proper cleanup in case
of a channel having two background copy operations running as is
now possible.

* tests/io.test (io-53.10): Testcase for bi-directionaly fcopy.
* generic/tclIO.c: Additional changes to data structures for fcopy
and channels to perform proper cleanup in case of a channel having
two background copy operations running as is now possible.

2008-04-07  Andreas Kupries  <andreask@activestate.com>

* generic/tclIO.c (BUSY_STATE, CheckChannelErrors,
TclCopyChannel): New macro, and the places using it. This change
allows for bi-directional fcopy on channels. [Bug 1350564]. Thanks
to Alexandre Ferrieux <ferrieux@users.sourceforge.net> for the

2008-04-07  Reinhard Max  <max@suse.de>

* generic/tclStringObj.c (Tcl_AppendFormatToObj): Fix [format {% d}]
so that it behaves the same way as in 8.4 and as C's printf().
* tests/format.test: Add a test for '% d' and '%+d'.

2008-04-05  Kevin B. Kenny  <kennykb@acm.org>

* tests/chanio.test (chan-io-53.9):
* tests/io.test (io-53.9): Made test cleanup robust against the
possibility of slow process shutdown on Windows.

* win/tcl.m4: Added -D_CRT_SECURE_NO_DEPRECATE and
-DCRT_NONSTDC_NO_DEPRECATE to the MSVC compilation flags so that
the compilation doesn't barf on perfectly reasonable Posix system
* win/configure: Manually patched (don't have the right autoconf
to hand).

* win/tclWinFile.c: (WinSymLinkDirectory): Fixed a problem that
Tcl was creating an NTFS junction point (IO_REPARSE_TAG_MOUNT_POINT)
but filling in the union member for a Vista symbolic link. We had
gotten away with this error because the union member
(SymbolicLinkReparseBuffer) was misdefined in this file and in the
'winnt.h' in early versions of MinGW. MinGW 3.4.2 has the correct
definition of SymbolicLinkReparseBuffer, exposing the mismatch,
and making tests cmdAH-19.4.1, fCmd-28.*, and filename-11.* fail.

2008-04-04  Andreas Kupries  <andreask@activestate.com>

* tests/io.test (io-53.9): Added testcase for [Bug 780533], based
* tests/chanio.test: on Alexandre's test script. Also fixed
problem with timer in preceding test, was not canceled properly in
the ok case.

2008-04-04  Andreas Kupries  <andreask@activestate.com>

* generic/tclIORChan.c (ReflectOutput): Allow zero return from
write when input was zero-length anyway. Otherwise keept it an
error, and separate the message from 'written too much'.

* tests/ioCmd.test (iocmd-24.6): Testcase updated for changed

* generic/tclIORChan.c (ReflectClose): Added missing removal of
the now closed channel from the reflection map. Before we could
crash the system by invoking 'chan postevent' on a closed
reflected channel, dereferencing the dangling pointer in the map.

* tests/ioCmd.test (iocmd-31.8): Testcase for the above.

2008-04-03  Andreas Kupries  <andreask@activestate.com>

* generic/tclIO.c (CopyData): Applied patch [Bug 1932639] to

<ferrieux@users.sourceforge.net> for report and patch.

2008-04-02  Andreas Kupries  <andreask@activestate.com>

* generic/tclIO.c (CopyData): Applied patch for the fcopy problem
[Bug 780533], with many thanks to Alexandre Ferrieux
<ferrieux@users.sourceforge.net> for tracking it down and
providing a solution. Still have to convert his test script into a
proper test case.

* generic/tclInt.h (TclIsNaN):
* unix/configure.in: Added code to the configurator to check for
                     a standard isnan() macro and use it if one
                     is found.  This change avoids bugs where
                     the test of ((d) != (d)) is optimized away
     by an overaggressive compiler. [Bug 1783544]
* generic/tclObj.c: Added missing #include <math.h> needed to
    locate isnan() after the above change.

* unix/configure: autoconf-2.61

* generic/tcl.h, generic/tclThreadAlloc.c: Tidied up the declarations
of Tcl_GetMemoryInfo so that it is always defined. Will panic when
called against a Tcl that was previously built without it at all,
which is OK because that also indicates a serious mismatch between
memory configuration options.

2008-03-19  Donal K. Fellows  <dkf@users.sf.net>

sure this function is available when direct linking. [Bug 1868171]

* tests/reg.test (reg-33.14): Marked nonPortable because some
environments have small default stack sizes. [Bug 1905562]

2008-03-18  Andreas Kupries  <andreask@activestate.com>

* library/tm.tcl (::tcl::tm::UnknownHandler): Changed 'source' to
'source -encoding utf-8'. This fixes a portability problem of Tcl
Modules pointed out by Don Porter. By using plain 'source' we were at
the mercy of 'encoding system', making modules less portable than they
could be. The exact scenario: A writes a TM in some weird encoding
which is A's system encoding, distributes it, and somewhere else it
cannot be read/used because the system encoding is different. Forcing
the use of utf-8 makes the module portable.

***INCOMPATIBILITY*** for all Tcl Modules already written in non-utf-8
compatible encodings.

alignment of memory allocated by GrowEvaluationStack(). [Bug 1914503]

2008-03-18  Andreas Kupries  <andreask@activestate.com>

* library/tm.tcl (::tcl::tm::Defaults): Modified handling of
environment variables. See [Bug 1914604]. Solution slightly different
than proposed in the report. Using the underscored form TCLX_y_TM_PATH
even if TCLX.y_TM_PATH exists. Also using a loop to cut prevent code

2008-03-16  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclCompCmds.c (TclCompileDictForCmd): Correct the handling
of stack space calculation (the jump pattern used was confusing the
simple-minded code doing the calculations). [Bug 1903325]

* doc/lreplace.n: Clarified documentation of what happens with
negative indices. [Bug 1905809] Added example, tidied up formatting.

2008-03-14  Don Porter <dgp@users.sourceforge.net>

* generic/tclBasic.c (OldMathFuncProc): Same workaround protection
from bad TclStackAlloc() alignment. Thanks George Peter Staplin.

* generic/tclCmdIL.c (Tcl_LsortObjCmd): Use ckalloc() to allocate
SortElement arrays instead of TclStackAlloc() which isn't getting
alignment right. Workaround for [Bug 1914503].

* generic/tclVar.c (TclDeleteNamespaceVars):

a FQ named during namespace deletion. This was causing infinite loops
when unset traces recreated the var, as reported by Julian Noble. [Bug

* doc/http.n: Revised to indicate that [package require http 2.5.5]
is needed to get all the documented commands ([http::meta]).

passing invalid return options dictionaries. [Bug 1901113]

* generic/tclBasic.c (ExprAbsFunc): Revised so that the abs()
* tests/expr.test: function and the [::tcl::mathfunc::abs]
command do not return the value of -0, or equivalent values with more
alarming string reps like -1e-350. [Bug 1893815]

2008-03-07  Andreas Kupries  <andreask@activestate.com>

* generic/tclResult.c (ReleaseKeys): Workaround for [Bug 1904907].
Reset the return option keys to NULL to allow full re-initialization
by GetKeys(). This introduces a memory leak for the key objects, but
gets us around a crash in the finalization of reflected channels when
handling returns, either at compile- or runtime. In both cases we
access the keys after they have been released by their thread exit
handler. A proper fix is entangled with the untangling of the
finalization ordering and attendant issues. For now we choose the
lesser evil.

2008-03-07  Don Porter <dgp@users.sourceforge.net>

* generic/tclExecute.c (Tcl_ExprObj): Revised expression bytecode
compiling so that bytecodes invalid due to changing context or due to
the difference between expressions and scripts are not reused. [Bug

* generic/tclCmdAH.c: Revised direct evaluation implementation of
[expr] so that [expr $e] caches compiled bytecodes for the expression
as the intrep of $e.

* tests/execute.test (execute-6.*): More tests checking that
script bytecode is invalidated in the right situations.

* generic/tclResult.c (Tcl_SetReturnOptions): Revised the refcount
management of Tcl_SetReturnOptions to become that of a conventional
Consumer routine.  Thanks to Peter Spjuth for pointing out the
difficulties calling Tcl_SetReturnOptions with non-0-count value for
* generic/tclExecute.c (INST_RETURN_STK): Revised the one caller
within Tcl itself which passes a non-0-count value to

* generic/tclBasic.c (Tcl_AppendObjToErrorInfo): Revised the
refcount management of Tcl_AppendObjToErrorInfo to become that of a
conventional Consumer routine. This preserves the ease of use for the
overwhelming common callers who pass in a 0-count value, but makes the
proper call with a non-0-count value less surprising.
* generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd): Revised the
one caller within Tcl itself which passes a non-0-count value to

2008-01-02  Donal K. Fellows  <dkf@users.sf.net>

* doc/binary.n: Fixed documentation bug reported on tcl-core, and
reordered documentation to discourage people from using the hex
formatter that is hardly ever useful.

* doc/dict.n: Clarified meaning of dictionary values following
discussion on comp.lang.tcl.

2007-12-26  Miguel Sofer  <msofer@users.sf.net>

* generic/tclCmdIL.c: More [lsort] data handling streamlines. The
function MergeSort is gone, essentially inlined into Tcl_LsortObjCmd.
It is not a straight inlining, two loops over all lists elements where
merged in the process: the linked list elements are now built and
merged into the temporary sublists in the same pass.

2007-12-25  Miguel Sofer  <msofer@users.sf.net>

* generic/tclCmdIL.c: More [lsort] data handling streamlines. Extra
mem reqs of latest patches removed, restored to previous mem profile.
Improved -unique handling, now eliminating repeated elems immediately
instead of marking them to avoid reinsertion at the end.

2007-12-23  Jeff Hobbs  <jeffh@ActiveState.com>

* generic/tclCompCmds.c (TclCompileRegexpCmd):  TCL_REG_NOSUB cannot
* tests/regexp.test (regexp-22.2): be used because it

calling SelectObjFromSublist when there are no sublists.

2007-12-21  Miguel Sofer  <msofer@users.sf.net>

* generic/tclCmdIL.c (Tcl_LsortObjCmd): Preallocate a listObj of
sufficient length for the sorted list instead of growing it. Second
commit replaces calls to Tcl_ListObjAppenElement with direct access to
the internal rep.

* generic/tclCmdMZ.c (Tcl_SwitchObjCmd):       command so that when
passed two arguments, no check for options are performed. This is OK
since in the two-arg case, detecting an option would definitely lead
to a syntax error. [Patch 1836519]

* generic/tclCompCmds.c (TclCompileDictAppendCmd): Fix bug in [dict
append] compiler which caused strange stack corruption. [Bug 1837392]

2007-11-23  Andreas Kupries  <andreask@activestate.com>

* generic/tclIORChan.c: Fixed a problem with reflected channels. 'chan
postevent' is defined to work only from within the interpreter
containing the handler command. Sensible, we want only handler
commands to use it. It identifies the channel by handle. The channel
moves to a different interpreter or thread. The interpreter containing
the handler command doesn't know the channel any longer. 'chan
postevent' fails, not finding the channel any longer. Uhm.

Fixed by creating a second per-interpreter channel table, just for
reflected channels, where each interpreter remembers for which
reflected channels it has the handler command. This info does not move
with the channel itself. The table is updated by 'chan create', and
used by 'chan postevent'.

* tests/ioCmd.test: Updated the testsuite.

2007-11-23  Jeff Hobbs  <jeffh@ActiveState.com>

* generic/tclVar.c (Tcl_ArrayObjCmd): handle the right data for

* generic/tclCmdMZ.c (Tcl_StringObjCmd): Rewrote the [string] and
* generic/tclDictObj.c (Tcl_DictObjCmd): [dict] implementations to be
ready for conversion to ensembles.

* tests/string.test (string-12.22): Flag shimmering bug found in
[string range].

2007-11-21  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclCompCmds.c (TclCompileEnsemble): Rewrote the ensemble
compiler to remove many of the limitations. Can now compile scripts
that use unique prefixes of subcommands, and which have mappings of a
command to multiple words (provided the first is a compilable command
of course).

2007-11-21  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

* generic/tclNamesp.c (TclMakeEnsemble): Factor out the code to set up
a core ensemble from a table of information about subcommands, ready
for reuse within the core.

* generic/various: Start to return more useful Error codes, currently
mainly on assorted lookup failures.

2007-11-20  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclDictObj.c: Changed the underlying implementation of the
hash table used in dictionaries to additionally keep all entries in
the hash table in a linked list, which is only ever added to at the
end. This makes iteration over all entries in the dictionary in
key insertion order a trivial operation, and so cleans up a great deal
of complexity relating to dictionary representation and stability of
iteration order.

For any code that depended on the (strange) old iteration order.

2007-11-15  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

* generic/tclNamesp.c (NamespaceEnsembleCmd): Must pass a non-NULL
interp to Tcl_SetEnsemble* functions.

* doc/re_syntax.n: Try to make this easier to read. It's still a very
difficult manual page!

* unix/tcl.m4 (SC_CONFIG_CFLAGS): Allow people to turn off the -rpath
option to their linker if they so desire. This is a configuration only
recommended for (some) vendors. Relates to [Patch 1231022].

2007-11-15  Pat Thoyts  <patthoyts@users.sourceforge.net>

in our INST_START_CMD calls right, even when there's a failure to
compile a command directly.

* generic/tclNamesp.c (Tcl_SetEnsembleSubcommandList)
(Tcl_SetEnsembleMappingDict): Special code to make sure that
* generic/tclCmdIL.c (TclInitInfoCmd): [info exists] is compiled right
while not allowing changes to the ensemble to cause havok.

* generic/tclCompCmds.c (TclCompileInfoCmd): Simple compiler for the
[info] command that only handles [info exists].

* generic/tclExecute.c (TclExecuteByteCode:INST_EXIST_*): New
instructions to allow the testing of whether a variable exists.

2007-11-14  Andreas Kupries  <andreask@activestate.com>

'io.test', with all channel commands converted to their 'chan xxx'
* tests/io.test: Fixed typo in test description.

2007-11-14  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

full code, it will remain on the 8.4 branch. [Bug 1831425]

2007-11-13  Jeff Hobbs  <jeffh@ActiveState.com>

literal regexps get fed to INST_REGEXP.

* doc/mathop.n: Clarify definitions of some operations.

2007-11-13  Miguel Sofer  <msofer@users.sf.net>

* unix/tclUnixInit.c: the TCL_NO_STACK_CHECK was being incorrectly
undefined here; this should be set (or not) in the compile options, it
is used elsewhere and needs to be consistent.

2007-11-13  Pat Thoyts  <patthoyts@users.sourceforge.net>

cheap no-op.

2007-11-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

thread-safe version of gethostbyname() by forward-porting the code used

if specified on error.

* generic/tclResult.c: nor errorInfo, return at normal level.
* generic/tclStubLib.c: [Patch 1830184]
* generic/tclUtil.c:

* generic/tclExecute.c, generic/tclInt.decls, generic/tclIntDecls.h:
* generic/tclRegexp.c, generic/tclRegexp.h: Add INST_REGEXP and fully
* generic/tclStubInit.c, generic/tclUtil.c: compiled [regexp] for the
* tests/regexpComp.test:     [Bug 1830166]  simple cases. Also added
TclReToGlob function to convert RE to glob patterns and use these in
the possible cases.

2007-11-11  Miguel Sofer  <msofer@users.sf.net>

* generic/tclResult.c (ResetObjResult): clarify the logic.

* generic/tclBasic.c: Increased usage of macros to detect
* generic/tclBinary.c: and take advantage of objTypes. Added
* generic/tclClock.c: macros TclGet(Int|Long)FromObj,
* generic/tclCmdAH.c: TclGetIntForIndexM & TclListObjLength,
* generic/tclCmdIL.c: modified TclListObjGetElements.
* generic/tclCmdMZ.c:
* generic/tclCompCmds.c: The TclGetInt* macros are only a
* generic/tclCompExpr.c: shortcut on platforms where 'long' is
* generic/tclCompile.c: 'int'; it may be worthwhile to extend
* generic/tclDictObj.c: their functionality to other cases.
* generic/tclExecute.c:

2007-11-11  Daniel Steffen  <das@users.sourceforge.net>

* unix/tclUnixTime.c (TclpWideClicksToNanoseconds): Fix issues with
* generic/tclInt.h:     int64_t overflow.

* generic/tclBasic.c: Fix stack check failure case if stack grows up
* unix/tclUnixInit.c: Simplify non-crosscompiled case.

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

2007-11-10  Miguel Sofer  <msofer@users.sf.net>

* generic/tclExecute.c: Fast path for INST_LIST_INDEX when the index is
not a list.

* generic/tclBasic.c:
* unix/configure.in:
* unix/tclUnixInit.c: Detect stack grwoth direction at compile time,
only fall to runtime detection when crosscompiling.

* unix/configure: autoconf 2.61

* generic/tclBasic.c:
* generic/tclInt.h:
* tests/interp.test:
* unix/tclUnixInit.c:
* win/tclWin32Dll.c: Restore simpler behaviour for stack checking, not
adaptive to stack size changes after a thread is launched. Consensus is
that "nobody does that", and so it is not worth the cost. Improved
failure comments (mistachkin).

2007-11-10  Kevin Kenny  <kennykb@acm.org>

* win/tclWin32Dll.c: Rewrote the Windows stack checking algorithm to
use information from VirtualQuery to determine the bound of the stack.
This change fixes a bug where the guard page of the stack was never
restored after an overflow. It also eliminates a nasty piece of
assembly code for structured exception handling on mingw. It introduces
an assumption that the stack is a single memory arena returned from
VirtualAlloc, but the code in MSVCRT makes the same assumption, so it
should be fairly safe.

2007-11-10  Miguel Sofer  <msofer@users.sf.net>

* generic/tclBasic.c:
* generic/tclInt.h:
* unix/tclUnixInit.c:
* unix/tclUnixPort.h:
* win/tclWin32Dll.c: Modify the stack checking algorithm to recheck in
case of failure. The working assumptions are now that (a) a thread's
stack is never moved, and (b) a thread's stack can grow but not shrink.
Port to windows - could be more efficient, but is already cheaper than
it was.

2007-11-09  Miguel Sofer  <msofer@users.sf.net>

* generic/tclResult.c (ResetObjResult): new shortcut.

* generic/tclAsync.c:
* generic/tclBasic.c:
* generic/tclExecute.c:
* generic/tclInt.h:
* generic/tclUnixInit.c:
* generic/tclUnixPort.h: New fields in interp (ekeko!) to cache TSD
data that is accessed at each command invocation, access macros to
replace Tcl_AsyncReady and TclpCheckStackSpace by much faster variants.
[Patch 1829248]

2007-11-09  Jeff Hobbs  <jeffh@ActiveState.com>

* generic/tclInt.decls, generic/tclIntDecls.h: Use unsigned char for

don't allow a nocase option. [Bug 1828296]
For INST_STR_MATCH, ignore pattern type for TclByteArrayMatch case.

* generic/tclBinary.c (Tcl_GetByteArrayFromObj): check type before
func jump (perf).

2007-11-07  Jeff Hobbs  <jeffh@ActiveState.com>

* generic/tclStubInit.c: Added TclByteArrayMatch
* generic/tclInt.decls: for efficient glob

* generic/tclIO.c (TclGetsObjBinary): Add an efficient binary path for
(DoWriteChars): Special case for 1-byte channel write.

2007-11-06  Miguel Sofer  <msofer@users.sf.net>

* generic/tclEncoding.c: Version of the embedded iso8859-1 encoding
handler that is faster (functions to do the encoding know exactly what
they're doing instead of pulling it from a table, though the table
itself has to be retained for use by shift encodings that depend on
iso8859-1). [Patch 1826906], committing for dkf.

2007-11-05  Andreas Kupries  <andreask@activestate.com>

* generic/tclConfig.c (Tcl_RegisterConfig): Modified to not extend the
config database if the encoding provided by the user is not found
(venc == NULL). Scripts expecting the data will error out, however we
neither crash nor provide bogus information. See [Bug 983509] for more

* unix/tclUnixChan.c (TtyGetOptionProc): Accepted [Patch 1823576]
provided by Stuart Cassof <stwo@users.sourceforge.net>. The patch adds
the necessary utf/external conversions to the handling of the arguments
of option -xchar which will allow the use of \0 and similar characters.

2007-11-03  Miguel Sofer  <msofer@users.sf.net>

* generic/tclTest.c (TestSetCmd2):
* generic/tclVar.c (TclObjLookupVarEx):
* tests/set.test (set-5.1): Fix error branch when array name looks
like array element (code not normally exercised).

2007-11-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

* tools/tcltk-man2html.tcl (output-directive): Convert .DS/.DE pairs
into tables since that is now all that they are used for.

* doc/RegExp.3: Clarified documentation of RE flags. [Bug 1167840]

* doc/refchan.n: Adjust internal name to be consistent with the file
name for reduced user confusion. After comment by Dan Steffen.

* generic/tclCmdMZ.c (Tcl_StringObjCmd, UniCharIsAscii): Remember, the
NUL character is in ASCII too. [Bug 1808258]

* doc/file.n: Clarified use of [file normalize]. [Bug 1185154]

2007-10-30  Don Porter <dgp@users.sourceforge.net>

concatenees being empty objs. [Bug 1447328]

2007-10-28  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclEncoding.c (TclInitEncodingSubsystem): Hard code the
iso8859-1 encoding, as it's needed for more than just text (especially
binary encodings...) Note that other encodings rely on the encoding
being a table encoding (!) so we can't use more efficient encoding
mapping functions.

2007-10-27  Donal K. Fellows  <dkf@users.sf.net>

* generic/regc_lex.c (lexescape): Close off one of the problems
mentioned in [Bug 1810264].

2007-10-27  Miguel Sofer  <msofer@users.sf.net>

* generic/tclNamesp.c (Tcl_FindCommand): insure that FQ command names
are searched from the global namespace, ie, bypassing resolvers of the
current namespace. [Bug 1114355]

* doc/apply.n: fixed example [Bug 1811791]

* generic/tclInt.h: moved declaration of TclSetCmdNameObj from
tclCompile.h to tclInt.h, reverting linker [Bug 1821159] caused by
commit of 2007-10-11 (both I and gcc missed one dep).

* generic/tclVar.c: try to preserve Tcl_Objs when doing variable
lookups by name, partially addressing [Bug 1793601].

2007-10-27  Donal K. Fellows  <dkf@users.sf.net>

* tools/tcltk-man2html.tcl (make-man-pages, htmlize-text)

2007-09-08  Miguel Sofer  <msofer@users.sf.net>

* generic/tclVar.c (Tcl_SetVar2, TclPtrSetVar): [Bug 1710710] fixed
correctly, reverted fix of 2007-05-01.

2007-09-08  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclDictObj.c (DictUpdateCmd, DictWithCmd): Plug a hole that
* generic/tclExecute.c (TEBC,INST_DICT_UPDATE_END): allowed a careful
* tests/dict.test (dict-21.16,21.17,22.11): attacker to craft a dict
containing a recursive link to itself, violating one of Tcl's
fundamental datatype assumptions and causing a stack crash when the
dict was converted to a string. [Bug 1786481]

2007-09-07  Don Porter <dgp@users.sourceforge.net>

* generic/tclEvent.c ([::tcl::Bgerror]): Corrections to Tcl's
* tests/event.test: default [interp bgerror] handler so that when
it falls back to a hidden [bgerror] in a safe interp, it gets the
right error context data. [Bug 1790274]

2007-09-07  Miguel Sofer  <msofer@users.sf.net>

2007-09-06  Don Porter <dgp@users.sourceforge.net>

* generic/tclResult.c (Tcl_GetReturnOptions): Take care that a
* tests/init.test: non-TCL_ERROR code doesn't cause existing
-errorinfo, -errorcode, and -errorline entries to be omitted.
* generic/tclEvent.c: With -errorInfo no longer lost, generate more
complete ::errorInfo when calling [bgerror] after a non-TCL_ERROR
background exception.

2007-09-06  Don Porter <dgp@users.sourceforge.net>

* generic/tclInterp.c (Tcl_Init): Removed constraint on ability
to define a custom [tclInit] before calling Tcl_Init(). Until now the
custom command had to be a proc. Now it can be any command.

* generic/tclInt.decls: New internal routine TclBackgroundException()
* generic/tclEvent.c: that for the first time permits non-TCL_ERROR
exceptions to trigger [interp bgerror] handling. Closes a gap in TIP
221. When falling back to [bgerror] (which is designed only to handle

* unix/Makefile.in: 1264623]

2007-09-04  Don Porter <dgp@users.sourceforge.net>

* unix/Makefile.in: It's unreliable to count on the release
manager to remember to `make genstubs` before `make dist`. Let the
Makefile remember the dependency for us.

* unix/Makefile.in: Corrections to `make dist` dependencies to be
sure that macosx/configure gets generated whenever it does not exist.

caused this call to return an empty object rather than an error.

* generic/tclCompile.c: Added fflush() calls following all callers of

output is less likely to get mangled when writes to stdout interleave
with other code.

2007-08-28  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c: Use a table lookup in ParseLexeme() to
determine lexemes with single-byte representations.

2007-08-27  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c: Call TclCompileSyntaxError() when
expression syntax errors are found when compiling expressions. With
this in place, convert TclCompileExpr to return void, since there's no
longer any need to report TCL_ERROR.
* generic/tclCompile.c: Update callers.
* generic/tclExecute.c:

* generic/tclCompCmds.c: New routine TclCompileSyntaxError()
* generic/tclCompile.h: to directly compile bytecodes that report a
* generic/tclCompile.c: syntax error, rather than (ab)use a call to
TclCompileReturnCmd. Also, undo the most recent commit that papered
over some issues with that (ab)use. New routine produces a new opcode
INST_SYNTAX, which is a minor variation of INST_RETURN_IMM. Also a bit
of constification.

* generic/tclCompile.c: Move the deallocation of local LiteralTable
* generic/tclCompExpr.c: entries into TclFreeCompileEnv().
* generic/tclExecute.c: Update callers.

* generic/tclCompExpr.c: Force numeric and boolean literals in
expressions to register with their intreps intact, even if that means
overwriting existing intreps in already registered literals.

2007-08-25  Kevin B. Kenny  <kennykb@acm.org>

* generic/tclExecute.c (TclExecuteByteCode): Added code to handle

that results in 32- and 64-bit integer results, avoiding calls to wide
integer exponentiation routines in this common case. [Bug 1767293]

2007-08-19  Miguel Sofer  <msofer@users.sf.net>

* generic/tclExecute.c: changed the check for overflow in sums,
reducing objsize, number of branches and cache misses (according to
cachegrind). Non-overflow for s=a+b:
  ((a >= 0 || b >= 0 || s < 0) && (s >= 0 || b < 0 || a < 0))
  (((a^s) >= 0) || ((a^b) < 0))
This expresses: "a and s have the same sign or else a and b have
different sign".

2007-08-16  Miguel Sofer  <msofer@users.sf.net>

* generic/tclVar.c: improved localVarNameType caching to leverage

before the switch. Reduces both runtime and obj size a tiny bit.

2007-08-16  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c: Added a "constant" field to the OpNode

number of arguments in a parsed function call. CompileExprTree() now
determines that for itself at compile time. Then reorder code to
eliminate duplication.

* unix/Makefile.in: add support for compile flags specific to
object files linked directly into executables.

* unix/configure.in (Darwin): only use -seg1addr flag when prebinding;
use -mdynamic-no-pic flag for object files linked directly into exes;
support overriding TCL_PACKAGE_PATH/TCL_MODULE_PATH in environment.

*** POTENTIAL INCOMPATIBILITY *** (tclInt.h and tclCompile.h)
Extensions that access internals defined in tclInt.h and/or
tclCompile.h may lose both binary and source compatibility. The
relevant changes are:
1. 'struct Var' is completely changed, all acceses to its internals
   (either direct or via the TclSetVar* and TclIsVar* macros) will
   malfunction. Var flag values and semantics changed too.
2. 'struct Bytecode' has an additional field that has to be
   initialised to NULL
3. 'struct Namespace' is larger, as the varTable is now one pointer
   larger than a Tcl_HashTable. Direct access to its fields will
4. 'struct CallFrame' grew one more field (the second such growth with
   respect to Tcl8.4).
5. API change for the functions TclFindCompiledLocal, TclDeleteVars
   and many internal functions in tclVar.c

Additionally, direct access to variable hash tables via the standard
Tcl_Hash* interface is to be considered as deprecated. It still works
in the present version, but will be broken by further specialisation
of these hash tables. This concerns especially the table of array
elements in an array, as well as the varTable field in the Namespace

replacement to fill the tcl_platform(user) field as it is not subject
to spoofing. [Bug 681877]

* unix/tclUnixCompat.c: Simplify the #ifdef logic.

* unix/tclUnixChan.c (FileWatchProc): Fix test failures.

2007-07-30  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

* unix/tclUnixChan.c (SET_BITS, CLEAR_BITS): Added macros to make this

* generic/tclBasic.c (TEOvI, GetCommandSource):
* generic/tclExecute.c (TEBC, TclGetSrcInfoForCmd):
* generic/tclInt.h:
* generic/tclTrace.c (TclCheck(Interp|Execution)Traces):
Removed the need for TEBC to inspect the command before calling TEOvI,
leveraging the TIP 280 infrastructure. Moved the generation of a
correct nul-terminated command string away from the trace code, back
into TEOvI/GetCommandSource.

2007-07-20  Andreas Kupries  <andreask@activestate.com>

* library/platform/platform.tcl: Fixed bug in 'platform::patterns'
* library/platform/pkgIndex.tcl: where identifiers not matching

* win/Makefile.in: get 'tcl' as an acceptable platform added to
* doc/platform.n: the result. Bumped package to version 1.0.3 and
* doc/platform_shell.n: updated documentation and Makefiles. Also
fixed bad version info in the documentation of platform::shell.

2007-07-19  Don Porter <dgp@users.sourceforge.net>

* generic/tclParse.c: In contexts where interp and parsePtr->interp
might be different, be sure to use the latter for error reporting.
Also pulled the interp argument back out of ParseTokens() since we
already had a parsePtr->interp to work with.

2007-07-18  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c: Removed unused arguments and variables

2007-07-17  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c (ParseExpr): While adding comments to
explain the operations of ParseExpr(), made significant revisions to
the code so it would be easier to explain, and in the process made the
code simpler and clearer as well.

2007-07-15  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c: More commentary.
* tests/parseExpr.test: Several tests of syntax error messages
to check that when expression substrings are truncated they leave
visible the context relevant to the reported error.

2007-07-12  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c: Factored out, corrected, and commented
common code for reporting syntax errors in LEAF elements.

2007-07-11  Miguel Sofer  <msofer@users.sf.net>

* generic/tclCompCmds.c (TclCompileWhileCmd):
* generic/tclCompile.c (TclCompileScript):
Corrected faulty avoidance of INST_START_CMD when the first opcode in
a script is within a loop (as produced by 'while 1'), so that the
corresponding command is properly counted. [Bug 1752146]

2007-07-11  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c: Added a "parseOnly" flag argument to
ParseExpr() to indicate whether the caller is Tcl_ParseExpr(), with an
end goal of filling a Tcl_Parse with Tcl_Tokens representing the
parsed expression, or TclCompileExpr() with the goal of compiling and
executing the expression. In the latter case, more aggressive
conversion of QUOTED and BRACED lexeme to literals is done. In the
former case, all such conversion is avoided, since Tcl_Token
production would revert it anyway. This enables simplifications to the
GenerateTokensForLiteral() routine as well.

2007-07-10  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c: Added a field for operator precedence
to be stored directly in the parse tree. There's no memory cost to
this addition, since that memory would have been lost to alignment
issues anyway. Also, converted precedence definitions and lookup
tables to use symbolic constants instead of raw number for improved
readability, and continued extending/improving/correcting comments.
Removed some unused counter variables. Renamed some variables for
clarity and replaced some cryptic logic with more readable macros.

2007-07-09  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c: Revision so that the END lexeme never
gets inserted into the parse tree. Later tree traversal never reaches
it since its location in the tree is not variable. Starting and
stopping with the START lexeme (node 0) is sufficient. Also finished
lexeme code commentary.

* generic/tclCompExpr.c: Added missing creation and return of
the Tcl_Parse fields that indicate error conditions. [Bug 1749987]

2007-07-05  Don Porter <dgp@users.sourceforge.net>

* library/init.tcl (unknown): Corrected inconsistent error message
in interactive [unknown] when empty command is invoked. [Bug 1743676]

2007-07-05  Miguel Sofer  <msofer@users.sf.net>

* generic/tclNamesp.c (SetNsNameFromAny):
* generic/tclObj.c (SetCmdNameFromAny): Avoid unnecessary
ckfree/ckalloc when the old structs can be reused.

2007-07-04  Miguel Sofer  <msofer@users.sf.net>

* generic/tclNamesp.c: Fix case where a FQ cmd or ns was being cached
* generic/tclObj.c:    in a different interp, tkcon. [Bug 1747512]

2007-07-03  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c: Revised #define values so that there
is now more expansion room to define more BINARY operators.

2007-07-02  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclHash.c (CompareStringKeys): Always use the strcmp()
version; the operation is functionally equivalent, the speed is
identical (up to measurement limitations), and yet the code is

* generic/tcl.h: Removed TCL_PRESERVE_BINARY_COMPATIBILITY and
* generic/tclHash.c: any code enabled when it is set to 0. We will
* generic/tclStubInit.c: always want to preserve binary compat
of the structs that appear in the interface through the 8.* series of
releases, so it's pointless to drag around this never-enabled

* generic/tclInt.decls: Revised the interfaces of the routines
* generic/tclExecute.c: TclStackAlloc and TclStackFree to make them
easier for callers to use (or more precisely, harder to misuse).
TclStackFree now takes a (void *) argument which is the pointer
intended to be freed. TclStackFree will panic if that's not actually
the memory the call will free. TSA/TSF also now tolerate receiving

* generic/tclCompile.c: reverted TclEvalObjvInternal and INST_INVOKE
* generic/tclExecute.c: to essentially what they were previous to the
* generic/tclBasic.c: commit of 2007-04-03 [Patch 1693802] and the
subsequent optimisations, as they break the new trace tests described

* generic/trace.test: added tests 36 to 38 for dynamic trace creation
and addition. These tests expose a change in dynamics due to a recent
round of optimisations. The "correct" behaviour is not described in
docs nor TIP 62.

2007-06-14  Miguel Sofer  <msofer@users.sf.net>

* generic/tclInt.decls:   Modif to the internals of TclObjInterpProc

* generic/tclProc.c (TclObjInterpProcCore): simplified obj management
in wrongNumArgs calls.

2007-06-14  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompile.c: SetByteCodeFromAny() can no longer return any
* generic/tclExecute.c: code other than TCL_OK, so remove code that
* generic/tclProc.c: formerly handled exceptional codes.

2007-06-13  Miguel Sofer  <msofer@users.sf.net>

* generic/tclExecute.c (TclCompEvalObj): missed update to "there is
always a valid frame".

* generic/tclProc.c (TclObjInterpProcCore): call TEBC directly instead
of going through TclCompEvalObj - no need to check the compilation's
freshness, this has already been done. This improves speed and should
also provide some relief to [Bug 1066755].

2007-06-12  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

* generic/tclBasic.c (Tcl_CreateInterp): Turn the [info] command into
* generic/tclCmdIL.c (TclInitInfoCmd): an ensemble, making it easier
for third-party code to plug into.

* generic/tclIndexObj.c (Tcl_WrongNumArgs):
* generic/tclNamesp.c, generic/tclInt.h (tclEnsembleCmdType): Make
Tcl_WrongNumArgs do replacement correctly with ensembles and other
sorts of complex replacement strategies.

2007-06-11  Miguel Sofer  <msofer@users.sf.net>

* generic/tclExecute.c: comments added to explain iPtr->numLevels

* generic/tclNamesp.c: tweaks to Tcl_GetCommandFromObj and
* generic/tclObj.c: TclGetNamespaceFromObj; modified the usage of
structs ResolvedCmdName and ResolvedNsname so that the field refNsPtr
is NULL for fully qualified names.

2007-06-10  Miguel Sofer  <msofer@users.sf.net>

* generic/tclBasic.c: Further TEOvI split, creating a new
* generic/tclCompile.h: TclEvalObjvKnownCommand() function to handle
* generic/tclExecute.c: commands that are already known and are not
traced. INST_INVOKE now calls into this function instead of inlining
parts of TEOvI. Same perf, better isolation.

***POTENTIAL INCOMPAT*** There is a subtle issue with the timing of
execution traces that is changed here - first change appeared in my
commit of 2007-04-03 [Patch 1693802], which caused some divergence
between compiled and non-compiled code.

2007-06-10  Jeff Hobbs <jeffh@ActiveState.com>

* README: updated links. [Bug 1715081]

* generic/tclExecute.c (TclExecuteByteCode): restore support for
INST_CALL_BUILTIN_FUNC1 and INST_CALL_FUNC1 bytecodes to support 8.4-
precompiled sources (math functions). [Bug 1720895]

2007-06-10  Miguel Sofer  <msofer@users.sf.net>

* generic/tclInt.h:
* generic/tclNamesp.c:
* generic/tclObj.c:
* generic/tclvar.c: new macros TclGetCurrentNamespace() and
TclGetGlobalNamespace(); Tcl_GetCommandFromObj and
TclGetNamespaceFromObj rewritten to make the logic clearer; slightly
faster too.

2007-06-09  Miguel Sofer  <msofer@users.sf.net>

* generic/tclExecute.c (INST_INVOKE): isolated two vars to the small
block where they are actually used.

* generic/tclObj.c (Tcl_GetCommandFromObj): rewritten to make the
logic clearer; slightly faster too.

* generic/tclBasic.c: Split TEOv in two, by separating a processor
for non-TCL_OK returns. Also split TEOvI in a full version that
handles non-existing and traced commands, and a separate shorter
version for the regular case.

* generic/tclBasic.c: Moved the generation of command strings for
* generic/tclTrace.c: traces: previously in Tcl_EvalObjv(), now in
TclCheck[Interp|Execution]Traces(). Also insured that the strings are
properly NUL terminated at the correct length. [Bug 1693986]

The functions TclCheckInterpTraces() and TclCheckExecutionTraces() (in
internal stubs) used to be noops if the command string was NULL, this
is not true anymore: if the command string is NULL, they generate an
appropriate string from (objc,objv) and use it to call the traces. The
caller might as well not call them with a NULL string if he was
expecting a noop.

* generic/tclBasic.c: Extend usage of TclLimitReady() and
* generic/tclExecute.c: (new) TclLimitExceeded() macros.
* generic/tclInt.h:

* generic/tclBasic.c: Removed code that dealt with
* generic/tclCompile.c: TCL_TOKEN_EXPAND_WORD tokens representing
* generic/tclCompile.h: expanded literal words. These sections were
mostly in place to enable [info frame] to discover line information in
expanded literals. Since the parser now generates a token for each
post-expansion word referring to the right location in the original
script string, [info frame] gets all the data it needs.

* generic/tclInt.h: Revised the parser so that it never produces
* generic/tclParse.c: TCL_TOKEN_EXPAND_WORD tokens when parsing an
* tests/parse.test: expanded literal word; that is, something like
{*}{x y z}. Instead, generate the series of TCL_TOKEN_SIMPLE_WORD
tokens to represent the words that expansion of the literal string
produces. [RFE 1725186]

error return doesn't prevent all literals getting placed on the
litList to be returned to the caller for freeing. Corrects some
memleaks. [Bug 1705778, leak K23]

2007-04-25  Daniel Steffen  <das@users.sourceforge.net>

copy license.terms to dist macosx dir; fix autoheader bits.

2007-04-24  Miguel Sofer  <msofer@users.sf.net>

* generic/tclListObj.c: reverting [Patch 738900] (committed on
2007-04-20). Causes some Tk test breakage of unknown importance, but
the impact of the patch itself is likely to be so small that it does
not warrant investigation at this time.

2007-04-24  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclDictObj.c (DictKeysCmd): Rewrote so that the lock on the
internal representation of a dict is only set when necessary. [Bug
1705778, leak K04]

case. [Bug 1705778, leak K05]

2007-04-24  Kevin B. Kenny  <kennykb@acm.org>

return from the 'binary format' command leaked the result buffer.
* generic/tclListObj.c (TclLsetFlat): Fixed a bug where the new list
under construction was leaked in the error case. [Bug 1705778, leaks
K13 and K14]

2007-04-24  Jeff Hobbs <jeffh@ActiveState.com>

* unix/Makefile.in (dist): add platform library package to src dist

2007-04-24  Don Porter <dgp@users.sourceforge.net>

literal Tcl_Obj was not getting freed. [Bug 1705778, leak #1 (new)]

* generic/tclNamesp.c (Tcl_DeleteNamespace): Corrected flaw in the
flag marking scheme to be sure that global namespaces are freed when
their interp is deleted. [Bug 1705778]

2007-04-24  Kevin B. Kenny  <kennykb@acm.org>

* generic/tclExecute.c (TclExecuteByteCode): Plugged six memory leaks
in bignum arithmetic.

return value from the "initialize" method of a channel handler.
(All of the above under [Bug 1705778])

2007-04-23  Daniel Steffen  <das@users.sourceforge.net>

2007-04-23  Don Porter <dgp@users.sourceforge.net>

* generic/tclVar.c (UnsetVarStruct): Make sure the
TCL_INTERP_DESTROYED flags gets passed to unset trace routines so they
can respond appropriately. [Bug 1705778, leak #9]

2007-04-23  Miguel Sofer  <msofer@users.sf.net>

* generic/tclCompile.c (TclFreeCompileEnv): Tip 280's new field

we'd run beyond the end of the 'pow10_wide' array if a number begins
with a string of more than 'maxpow10_wide' zeroes.
* generic/tclTest.c (Testregexpobjcmd): Removed an invalid access
beyond the end of 'objv' in 'testregexp -about'.
All of these issues reported under [Bug 1705778] - detected with the
existing test suite, no new regression tests required.

2007-04-22  Miguel Sofer  <msofer@users.sf.net>

* generic/tclVar.c (TclDeleteNamespaceVars): fixed access to freed
memory detected by valgrind: Tcl_GetCurrentNamespace was being
called after freeing root CallFrame (on interp deletion).

2007-04-20  Miguel Sofer  <msofer@users.sf.net>

* generic/tclListObj.c (SetListFromAny): avoid discarding internal
reps of objects converted to singleton lists. [Patch 738900]

2007-04-20  Kevin B. Kenny  <kennykb@acm.org>

* doc/clock.n: Corrected a silly error (transposed 'uppercase' and
'lowercase' in clock.n. [Bug 1656002]
Clarified that [clock scan] does not recognize a locale's alternative
Deleted an entirely superfluous (and also incorrect) remark about the
effect of Daylight Saving Time on relative times in [clock scan]. [Bug

on input.
* library/msgs/ja.msg:
* tools/loadICU.tcl: Corrected several localisation faults in the
Japanese locale (most notably, incorrect dates for the Emperors'

pointing this out and developing a fix.
* generic/tclPathObj.c: Corrected a 'const'ness fault that caused
bitter complaints from MSVC.
* tests/clock.test (clock-40.1, clock-58.1, clock-59.1): Corrected a
test case that depended on ":localtime" being able to handle dates
prior to the Posix epoch. [Bug 1618445] Added a test case for the
dates of the Japanese emperors. [Bug 1637471] Added a regression test
for military time zone input conversion. [Bug 1586828]
* generic/tclGetDate.y (MilitaryTable): Fixed an ancient bug where the
military NZA time zones had the signs reversed. [Bug 1586828]
* generic/tclDate.c: Regenerated.

2007-04-18  Miguel Sofer  <msofer@users.sf.net>

* generic/tclExecute.c (INST_LSHIFT): fixed a mistake introduced in
version 1.266 ('=' became '=='), which effectively turned the block
that handles native shifts into dead code. This explains why the
testsuite did not pick this mistake. Rewrote to make the intention

* generic/tclInt.h (TclDecrRefCount): change the order of the
branches, use empty 'if ; else' to handle use in unbraced outer
if/else conditions (as already done in tcl.h)

* generic/tclExecute.c: slight changes in Tcl_Obj management.

2007-04-17  Kevin B. Kenny  <kennykb@acm.org>

* library/clock.tcl: Fixed the naming of
::tcl::clock::ReadZoneinfoFile because (yoicks!) it was in the global

recognized. [Bug 1656002]

2007-04-17  Miguel Sofer  <msofer@users.sf.net>

function definitions from manually-written code.

2007-04-15  Kevin B. Kenny  <kennykb@acm.org>

* generic/tclCompCmds.c: added a cast to silence a compiler error on
* library/clock.tcl: Restored unique-prefix matching of keywords on
the [clock] command. [Bug 1690041]

tosPtr from TEBC (after initialisation and the code at the label

2007-04-11  Miguel Sofer  <msofer@users.sf.net>

* generic/tclCompCmds.c: moved all exceptDepth management to the
macros - the decreasing half was managed by hand.

2007-04-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

* generic/tclInt.h (TclNewLiteralStringObj): New macro to make
allocating literal string objects (i.e. objects whose value is a
constant string) easier and more efficient, by allowing the omission
of the length argument. Based on [Patch 1529526] (afredd)
* generic/*.c: Make use of this (in many files).

2007-04-08  Miguel Sofer  <msofer@users.sf.net>

2007-04-01  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclCompile.c (TclCompileScript, TclPrintInstruction):
* generic/tclExecute.c (TclExecuteByteCode): Changed the definition of
INST_START_CMD so that it knows how many commands start at the current
location. This makes the interpreter command counter correct without
requiring a large number of instructions to be issued. (See my change
from 2007-01-19 for what triggered this.)

2007-03-30  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompile.c:
* generic/tclCompExpr.c:
* generic/tclCompCmds.c: Replace arrays on the C stack and
ckalloc calls with TclStackAlloc calls to use memory on Tcl's
evaluation stack.

implementation to reduce number of allocs/copies.

* tests/string.test:  More [string reverse] tests.

2007-03-30  Miguel Sofer  <msofer@users.sf.net>

2007-03-29  Miguel Sofer  <msofer@users.sf.net>

* generic/tclProc.c (Tcl_ApplyObjCmd):
* tests/apply.test (9.3): Fixed Tcl_Obj leak on error return; an
unneeded ref to lambdaPtr was being set and not released on an error
return path.

2007-03-28  Don Porter <dgp@users.sourceforge.net>

* generic/tclCmdMZ.c (STR_REVERSE): Implement the actual [string
reverse] command in terms of the new TclStringObjReverse() routine.

* generic/tclInt.h (TclStringObjReverse): New internal routine
* generic/tclStringObj.c (TclStringObjReverse): that implements the
[string reverse] operation, making use of knowledge/surgery of the
String intrep to minimize the number of allocs and copies needed to do
the job.

2007-03-27  Don Porter <dgp@users.sourceforge.net>

* generic/tclCmdMZ.c (STR_MAP): Replace ckalloc calls with
TclStackAlloc calls.

2007-03-24  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

* win/tclWinThrd.c: Thread exit handler marks the current thread as
un-initialized. This allows exit handlers that are registered later to
re-initialize this subsystem in case they need to use some sync
primitives (cond variables) from this file again.

2007-03-23  Miguel Sofer  <msofer@users.sf.net>

* generic/tclBasic.c (DeleteInterpProc): pop the root frame pointer
before deleting the global namespace [Bug 1658572]

into LIBRARY_DIR when doing 'make test' or 'make runtest'.

2007-03-22  Don Porter <dgp@users.sourceforge.net>

* generic/tclCmdAH.c (Tcl_ForeachObjCmd): Replaced arrays on the
C stack and ckalloc calls with TclStackAlloc calls to use memory on
Tcl's evaluation stack.

* generic/tclExecute.c: Revised GrowEvaluationStack to take an
argument specifying the growth required by the caller, so that a
single reallocation / copy is the most that will ever be needed even
when required growth is large.

2007-03-21  Don Porter <dgp@users.sourceforge.net>

* generic/tclExecute.c: More ckalloc -> ckrealloc conversions.
* generic/tclLiteral.c:

for lists passed to the [lset] command. Thanks to Don Porter for
fixing this issue. [Bug 1677512]

2007-03-19  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompile.c: Revise the various expansion routines for
CompileEnv fields to use ckrealloc() where appropriate.

* generic/tclBinary.c (Tcl_SetByteArrayLength): Replaced ckalloc() /
memcpy() sequence with ckrealloc() call.

* generic/tclBasic.c (Tcl_CreateMathFunc): Replaced some calls to

<chpock@gmail.com> for reporting this.

2007-03-17  Kevin B. Kenny  <kennykb@acm.org>

* win/tclWinReg.c (GetKeyNames): Size the buffer for enumerating key

2007-03-15  Mo DeJong  <mdejong@users.sourceforge.net>

* generic/tclIOUtil.c (Tcl_Stat): Reimplement workaround to avoid gcc
warning by using local variables. When the macro argument is of type
long long instead of long, the incorrect warning is not generated.

2007-03-15  Mo DeJong  <mdejong@users.sourceforge.net>

* win/Makefile.in: Fully qualify LIBRARY_DIR so that `make test` does
not depend on working dir.

2007-03-15  Mo DeJong  <mdejong@users.sourceforge.net>

* tests/parse.test: Add two backslash newline parse tests.

2007-03-12  Don Porter <dgp@users.sourceforge.net>

* generic/tclExecute.c (INST_FOREACH_STEP4): Make private copy of
* tests/foreach.test (foreach-10.1): value list to be assigned to
variables so that shimmering of that list doesn't lead to invalid
pointers. [Bug 1671087]

* generic/tclEvent.c (HandleBgErrors): Make efficient private copy
* tests/event.test (event-5.3): of the command prefix for the interp's
background error handling command to avoid panics due to pointers to
memory invalid after shimmering. [Bug 1670155]

* tests/namespace.test (namespace-42.8): private copy of the
command prefix as we invoke the command appropriate to a particular
subcommand of a particular ensemble to avoid panic due to shimmering
of the List intrep. [Bug 1670091]

* generic/tclVar.c (TclArraySet): Make efficient private copy of
* tests/var.test (var-17.1): the "list" argument to [array set] to

correctly reversed even if its internal representation is shared
without the object itself being shared. [Bug 1675044]

2007-03-10  Miguel Sofer  <msofer@users.sf.net>

* generic/tclCmdIL (Tcl_LsortObjCmd): changed fix to [Bug 1675116] to
use the cheaper TclListObjCopy() instead of Tcl_DuplicateObj().

2007-03-09  Andreas Kupries  <andreask@activestate.com>

* library/platform/shell.tcl: Made more robust if an older platform
* library/platform/pkgIndex.tcl: package is present in the inspected
* unix/Makefile.in: shell. Package forget it to prevent errors. Bumped
* win/Makefile.in: package version to 1.1.3, and updated the Makefiles
installing it as Tcl Module.

to shimmering. [Bug 1675116]

2007-03-09  Kevin B. Kenny  <kennykb@acm.org>

* library/clock.tcl (ReadZoneinfoFile): Added Y2038 compliance to the
code for version-2 'zoneinfo' files.
* tests/clock.test (clock-56.3): Added a test case for Y2038 and
'zoneinfo'. Modified test initialisation to use the
'loadTestedCommands' function of tcltest to bring in the correct path
for the registry library.

2007-03-08  Don Porter <dgp@users.sourceforge.net>

* generic/tclListObj.c (TclLsetList): Rewrite so that the routine
itself does not do any direct intrep surgery. Better isolates those
things into the implementation of the "list" Tcl_ObjType.

2007-03-08  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

* generic/tclListObj.c (TclLindexList, TclLindexFlat): Moved these
functions to tclListObj.c from tclCmdIL.c to mirror the way that the
equivalent functions for [lset]'s guts are arranged.

2007-03-08  Kevin B. Kenny  <kennykb@acm.org>

* library/clock.tcl: Further tweaks to the Windows time zone table
(restoring missing Mexican time zones). Added rudimentary handling of
version-2 'zoneinfo' files. Update US DST rules so that zones such as
'EST5EDT' get the correct transition dates.

parsing. Adjusted several tests that depended on obsolete US DST
transition rules.

2007-03-07  Daniel Steffen  <das@users.sourceforge.net>

* macosx/Tcl.xcodeproj/project.pbxproj: ensure gcc version used by
* macosx/Tcl.xcodeproj/default.pbxuser: Xcode and configure/make are
* macosx/Tcl-Common.xcconfig: consistent and independent of
gcc_select default and CC env var; fixes for Xcode 3.0.

* unix/tcl.m4 (Darwin): s/CFLAGS/CPPFLAGS/ in macosx-version-min check
* unix/configure: autoconf-2.59

2007-03-07  Don Porter <dgp@users.sourceforge.net>

* generic/tclCmdIL.c (TclLindex*): Rewrites to make efficient
private copies of the list and indexlist arguments, so we can operate
on the list elements directly with no fear of shimmering effects.
Replaces defensive coding schemes that are otherwise required. End
result is that TclLindexList is entirely a wrapper around
TclLindexFlat, which is now the core engine of all [lindex]

* generic/tclObj.c (Tcl_AppendAllObjTypes): Converted to simpler
list validity test.

2007-03-07  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

* generic/tclRegexp.c (TclRegAbout): Generate information about a
regexp as a Tcl_Obj instead of as a string, which is more efficient.

2007-03-07  Kevin B. Kenny  <kennykb@acm.org>

* library/clock.tcl: Adjusted Windows time zone table to handle new US
DST rules by locale rather than as Posix time zone spec.
* tests/clock.test (clock-39.6, clock-49.2, testclock::registry):
Adjusted tests to simulate new US rules.
* library/tzdata/America/Indiana/Winamac:
* library/tzdata/Europe/Istanbul:
* library/tzdata/Pacific/Easter:
Olson's tzdata2007c.

2007-03-05  Andreas Kupries  <andreask@activestate.com>

* library/platform/shell.tcl (::platform::shell::RUN): In the case of
* library/platform/pkgIndex.tcl: a failure put the captured stderr
* unix/Makefile.in: into the error message to aid in debugging. Bumped
* win/Makefile.in: package version to 1.1.2, and updated the makefiles
installing it as Tcl Module.

2007-03-03  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclLink.c (LinkedVar): Added macro to conceal at least some
of the pointer hackery.

2007-03-02  Don Porter <dgp@users.sourceforge.net>

* generic/tclCmdIL.c (Tcl_LreverseObjCmd): Added missing
TclInvalidateStringRep() call when we directly manipulate the intrep
of an unshared "list" Tcl_Obj. [Bug 1672585]

* generic/tclCmdIL.c (Tcl_JoinObjCmd): Revised [join] implementation
to append Tcl_Obj's instead of strings. [RFE 1669420]

2007-03-02  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

* generic/tclCompile.c (TclPrintInstruction): Added a scheme to allow
* generic/tclCompile.h (AuxDataPrintProc):    aux-data to be printed
* generic/tclCompCmds.c (Print*Info):       out for debugging. For
this to work, immediate operands referring to aux-data must be
identified as such in the instruction descriptor table using
OPERAND_AUX4 (all are always 4 bytes).

2007-03-01  Don Porter <dgp@users.sourceforge.net>

* generic/tclCmdIL.c (Tcl_LinsertObjCmd): Code simplifications
and optimizations.

* generic/tclCmdIL.c (Tcl_LreplaceObjCmd): Code simplifications
and optimizations.

* generic/tclCmdIL.c (Tcl_LrangeObjCmd): Rewrite in the same
spirit; avoid shimmer effects rather than react to them.

* generic/tclCmdAH.c (Tcl_ForeachObjCmd): Stop throwing away
* tests/foreach.test (foreach-1.14): useful error information when
loop variable sets fail.

* generic/tclCmdIL.c (Tcl_LassignObjCmd): Rewrite to make an
efficient private copy of the list argument, so we can operate on the
list elements directly with no fear of shimmering effects. Replaces
defensive coding schemes that are otherwise required.

* generic/tclCmdAH.c (Tcl_ForeachObjCmd): Rewrite to make
efficient private copies of the variable and value lists, so we can
operate on them without any special shimmer defense coding schemes.

2007-02-26  Andreas Kupries  <andreask@activestate.com>

* generic/tclIORChan.c (FreeReflectedChannel): Added the missing
refcount release between NewRC and FreeRC for the channel handle
object, spotted by Don Porter. [Bug 1667990]

2007-02-26  Don Porter <dgp@users.sourceforge.net>

* generic/tclCmdAH.c (Tcl_ForeachObjCmd): Removed surplus
copying of the objv array that used to be a workaround for [Bug
404865]. That bug is long fixed.

2007-02-24  Don Porter <dgp@users.sourceforge.net>

* generic/tclBasic.c: Use new interface in Tcl_EvalObjEx so that the
recounting logic of the List internal rep need not be repeated there.
Better encapsulation of internal details.

* generic/tclInt.h: New internal routine TclListObjCopy() used
* generic/tclListObj.c: to efficiently do the equivalent of [lrange
$list 0 end]. After some experience with this, might be a good
candidate for exposure as a public interface. It's useful for callers
of Tcl_ListObjGetElements() who want to control the ongoing validity
of the returned objv pointer.

2007-02-22  Andreas Kupries  <andreask@activestate.com>

* tests/pkg.test: Added tests for the case of an alpha package
satisfying a require for the regular package, demonstrating a corner
case specified in TIP#280. More notes in the comments to the test.

2007-02-13  Kevin B. Kenny  <kennykb@acm.org>

* tools/fix_tommath_h.tcl: Further tweaking for the x86-64. The change
is to make 'mp_digit' be an 'unsigned int' on that platform; since
we're using only 32 bits of it, there's no reason to make it a 64-bit
'unsigned long.'
* generic/tclTomMath.h: Regenerated.

* tools/fix_tommath_h.tcl: Added code to patch out a check for
__x86_64__ that caused Tommath to use __attributes(TI)__ for the
mp_word type. Tetra-int's simply fail on too many gcc-glibc-OS
combinations to be ready for shipment today, even if they work for
some of us. This change allows reversion of das's change of 2006-08-18
that accomplised the same thing on Darwin. [Bugs 1601380, 1603737,

* unix/configure.in: avoid replicating them across multiple
* macosx/Tcl.xcodeproj/project.pbxproj: buildsystems.

* unix/tcl.m4: ensure CPPFLAGS env var is used when set. [Bug 1586861]
(Darwin): add -isysroot and -mmacosx-version-min flags to CPPFLAGS
when present in CFLAGS to avoid discrepancies between what headers
configure sees during preprocessing tests and compiling tests.

2007-01-18  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

* generic/tclCompile.c (TclCompileScript): Make sure that when parsing

issued. [Bug 1638414]. Also make sure that the start of the expansion
bytecode sequence falls inside the span of bytecodes for a command.
* tests/compile.test (compile-16.24): Added test for [Bug 1638414]

* doc/string.n: Fix example. [Bug 1615277]

2006-12-12  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c: Now that the new internal structs are
in use to support operator commands, might as well make them the
default for [expr] as well and avoid passing every parsed expression
through the inefficient Tcl_Token array format. This addresses most
issues in [RFE 1517602]. Assuming no performance disasters result from
this, much dead code supporting the other implementation might now be

* generic/tclBasic.c: Final step routing all direct evaluation forms
* generic/tclCompExpr.c: of the operator commands through TEBC,
* generic/tclCompile.h: dropping all the routines in tclMathOp.c.
* generic/tclMathOp.c: Still needs Engineering Manual attention.

2006-12-11  Don Porter <dgp@users.sourceforge.net>

* generic/tclBasic.c: Another step with all sorting operator
* generic/tclCompExpr.c: commands now routing through TEBC via
* generic/tclCompile.h: TclSortingOpCmd().

2006-12-08  Don Porter <dgp@users.sourceforge.net>

* generic/tclBasic.c: Another step down the path of re-using
* generic/tclCompExpr.c: TclExecuteByteCode to implement the TIP 174
* generic/tclCompile.h: commands instead of using a mass of code
* generic/tclMathOp.c: duplication. Now all operator commands that
* tests/mathop.test: demand exactly one operation are implemented
via TclSingleOpCmd and a call to TEBC.

* generic/tclCompExpr.c: Revised implementation of TclInvertOpCmd to
* generic/tclMathOp.c: perform a bytecode compile / execute sequence.
This demonstrates a path toward avoiding mountains of code duplication
in tclMathOp.c and tclExecute.c.

* generic/tclCompile.h: Change TclExecuteByteCode() from static to
* generic/tclExecute.c: MODULE_SCOPE so all files including
tclCompile.h may call it.

* generic/tclMathOp.c: More revisions to make tests pass.

* generic/tclCompCmds.c: Additional commits correct most
* generic/tclExecute.c: failing tests illustrating bugs
* generic/tclMathOp.c: uncovered in [Patch 1578137].

* generic/tclBasic.c: Biggest source of TIP 174 failures was that
the commands were not [namespace export]ed from the ::tcl::mathop
namespace. More bits from [Patch 1578137] correct that.

* tests/mathop.test: Commmitted several new tests from Peter Spjuth
found in [Patch 1578137]. Many failures now demonstrate issues to fix
in the TIP 174 implementation.

2006-12-07  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

* tests/mathop.test: Added tests for ! ~ eq operators.

generation for the chained comparison operators.

the new TIP 174 commands. This corrects some known bugs. More to come.

2006-12-06  Kevin B. Kenny  <kennykb@acm.org>

* generic/tclPkg.c: When no requirements are supplied to a
* tests/pkg.test: [package require $pkg] and [package unknown]
is invoked to find a satisfying package, pass the requirement argument
"0-" (which means all versions are acceptable). This permits a
registered [package unknown] command to call [package vsatisfies
$testVersion {*}$args] without any special handling of the empty $args
case. This fixes/avoids a bug in [::tcl::tm::UnknownHandler] that was
causing old TM versions to be provided in preference to newer TM
versions. Thanks to Julian Noble for discovering the issue.

* generic/tclCompExpr.c: Added implementation for the
CompileExprTree() routine that can produce expression bytecode
directly from internal structures with no need to pass through the
Tcl_Token array representation. Still disabled by default. #undef
USE_EXPR_TOKENS to try it out.

2006-12-03  Don Porter <dgp@users.sourceforge.net>

* generic/tclCompExpr.c: Added expr parsing routines that
produce a different set of internal structures representing the parsed
expression, as well as routines that go on to convert those structures
into the traditional Tcl_Token array format. Use of these routines is
currently disabled. #undef PARSE_DIRECT_EXPR_TOKENS to enable them.
These routines will only become really useful when more routines that
compile directly from the new internal structures are completed.

2006-11-27  Kevin B. Kenny  <kennykb@acm.org>

* unix/tclUnixChan.c (TclUnixWaitForFile):
* tests/event.test (event-14.*): Corrected a bug where
TclUnixWaitForFile would present select() with the wrong mask on an
LP64 machine if a fd number exceeds 32. Thanks to Jean-Luc Fontaine
for reporting and diagnosing [Bug 1602208].

2006-11-27  Don Porter <dgp@users.sourceforge.net>

* generic/tclExecute.c (TclIncrObj): Correct failure to detect
floating-point increment values. Thanks to William Coleda [Bug

2006-11-26  Donal K. Fellows  <dkf@users.sf.net>

* tests/mathop.test, doc/mathop.n: More bits and pieces of the TIP#174
implementation. Note that the test suite is not yet complete.

2006-11-26  Daniel Steffen  <das@users.sourceforge.net>

* unix/tcl.m4 (Linux): --enable-64bit support. [Patch 1597389]

2006-11-25  Donal K. Fellows  <dkf@users.sf.net>


* generic/tclMathOp.c (new file): Completed the implementation of the
interpreted versions of all the tcl::mathop commands. Moved to a new
file to make tclCompCmds.c more focused in purpose.

2006-11-23  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclCompCmds.c (Tcl*OpCmd, TclCompile*OpCmd):
* generic/tclBasic.c (Tcl_CreateInterp): Partial implementation of
TIP#174; the commands are compiled, but (mostly) not interpreted yet.

2006-11-22  Donal K. Fellows  <dkf@users.sf.net>


* generic/tclCmdMZ.c (Tcl_StringObjCmd): Implementation of the [string
* tests/string.test (string-25.*): is list] command, based on
* doc/string.n: work by Joe Mistachkin, with
enhancements by Donal Fellows for better failindex behaviour.

2006-11-22  Don Porter <dgp@users.sourceforge.net>

* tools/genWinImage.tcl (removed): Removed two files used in
* win/README.binary (removed): production of binary distributions
for Windows, a task we no longer perform. [Bug 1476980]
* generic/tcl.h: Remove mention of win/README.binary in comment

* generic/tcl.h: Moved TCL_REG_BOSONLY #define from tcl.h to
* generic/tclInt.h: tclInt.h. Only know user is Expect, which
already #include's tclInt.h. No need to continue greater exposure.
[Bug 926500]

2006-11-20  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclBasic.c (Tcl_CreateInterp, TclHideUnsafeCommands):
* library/init.tcl: Refactored the [chan] command's guts so that it
does not use aliases to global commands, making the code more robust.

2006-11-17  Don Porter <dgp@users.sourceforge.net>

* generic/tclExecute.c (INST_EXPON): Corrected crash on
[expr 2**(1<<63)]. Was operating on cleared bignum Tcl_Obj.

2006-11-16  Donal K. Fellows  <dkf@users.sf.net>

* doc/apply.n, doc/chan.n: Added examples.

2006-11-15  Don Porter <dgp@users.sourceforge.net>

variadic prototypes with more than one fixed argument. (This is
possible since TCL_VARARGS and its limitations are no longer in use).
* generic/tcl.h: Some reordering so that macro definitions do
not interfere with the now _ANSI_ARGS_-less stub declarations.

(Tcl_FinalizeThreadStorage): Silence a compiler warning about
presenting a volatile pointer to 'memset'.

2006-11-13  Don Porter <dgp@users.sourceforge.net>

* generic/tclIO.c: When [gets] on a binary channel needs to use
the "iso8859-1" encoding, save a copy of that encoding per-thread to
avoid repeated freeing and re-loading of it from the file system. This
replaces the cached copy of this encoding that the platform
initialization code used to keep in pre-8.5 releases.

2006-11-13  Daniel Steffen  <das@users.sourceforge.net>

TclObjLookupVar to the internal stubs table.

2006-11-10  Daniel Steffen  <das@users.sourceforge.net>

* tests/fCmd.test (fCmd-6.26): fix failure when env(HOME) path
contains symlinks.

* macosx/Tcl.xcodeproj/project.pbxproj: remove tclParseExpr.c; when
running testsuite from inside Xcdoe, skip stack-3.1 (it only fails
under those circumstances).

* unix/tcl.m4 (Darwin): suppress linker arch warnings when building
universal for both 32 & 64 bit and no 64bit CoreFoundation is
available; sync with tk tcl.m4 change.
* unix/configure.in: whitespace.
* unix/configure: autoconf-2.59

2006-11-09  Don Porter <dgp@users.sourceforge.net>

* generic/tclParseExpr.c (removed): Moved all the code of
* generic/tclCompExpr.c: tclParseExpr.c into tclCompExpr.c.
* unix/Makefile.in: This sets the stage for expr compiling to work
* win/Makefile.in: directly with the full parse tree structures,
* win/makefile.bc: and not have to pass through the information
* win/makefile.vc: lossy format of an array of Tcl_Tokens.
* win/tcl.dsp:

2006-11-09  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>


* generic/tclCmdMZ.c (Tcl_StringObjCmd):    Implementation of the

2006-11-07  Andreas Kupries  <andreask@activestate.com>

* unix/tclUnixFCmd.c (CopyFile): Added code to fall back to a
hardwired default block size should the filesystem report a bogus
value. [Bug 1586470]

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

* generic/tclStringObj.c: Changed Tcl_ObjPrintf() response to an
invalid format specifier string. No longer panics; now produces an
error message as output.


* generic/tclParseExpr.c: Exponentiation operator is now right
* tests/expr.test: associative. [Patch 1556802]

2006-11-03  Miguel Sofer  <msofer@users.sf.net>

* generic/tclBasic.c (TEOVI): fix por possible leak of a Command in
the presence of execution traces that delete it.

* generic/tclBasic.c (TEOVI):
* tests/trace.test (trace-21.11): fix for [Bug 1590232], execution
traces may cause a second command resolution in the wrong namespace.

2006-11-03  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

* tests/event.test (event-11.5): Rewrote tests to stop Tcl from
* tests/io.test (multiple tests): opening sockets that are
* tests/ioCmd.test (iocmd-15.1,16,17): reachable from outside hosts
* tests/iogt.test (__echo_srv__.tcl): where not necessary. This is
* tests/socket.test (multiple tests): noticably annoying on some

2006-11-02  Daniel Steffen  <das@users.sourceforge.net>

2006-11-02  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

* generic/tclBasic.c, generic/tclInterp.c, generic/tclProc.c: Silence
warnings from gcc over signed/unsigned and TclStackAlloc().
* generic/tclCmdMZ.c: Update to more compact and clearer coding style.

2006-11-02  Don Porter <dgp@users.sourceforge.net>

* generic/tclCmdAH.c: Further revisions to produce the routines
* generic/tclInt.h: TclFormat() and TclAppendFormatToObj() that
* generic/tclNamesp.c: accept (objc, objv) arguments rather than
* generic/tclStringObj.c: any varargs stuff.

* generic/tclBasic.c: Further revised TclAppendPrintToObj() and
* generic/tclCkalloc.c: TclObjPrintf() routines to panic when unable
* generic/tclCmdAH.c: to complete their formatting operations,
* generic/tclCmdIL.c: rather than report an error message. This
* generic/tclCmdMZ.c: means an interp argument for error message

2006-11-02  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

* tests/winPipe.test (winpipe-4.[2345]): Made robust when run in
directory with spaces in its name.

* generic/tclCmdAH.c: Clean up uses of cast NULLs.

* generic/tclInterp.c (AliasObjCmd): Added more explanatory comments.

* generic/tclBasic.c (TclEvalObjvInternal): Rewrote so that comments
are relevant and informative once more. Also made the unknown handler
processing use the Tcl execution stack for working space, and not the
general heap.

2006-11-01  Daniel Steffen  <das@users.sourceforge.net>

* unix/tclUnixPort.h: ensure MODULE_SCOPE is defined before use, so
that tclPort.h can once again be included without tclInt.h.

* generic/tclEnv.c (Darwin): mark _environ symbol as unexported even
when MODULE_SCOPE != __private_extern__.

2006-10-31  Don Porter <dgp@users.sourceforge.net>

* generic/tclBasic.c: Refactored and renamed the routines
* generic/tclCkalloc.c: TclObjPrintf, TclFormatObj, and
* generic/tclCmdAH.c: TclFormatToErrorInfo to a new set of routines
* generic/tclCmdIL.c: TclAppendPrintfToObj, TclAppendFormatToObj,

* generic/tclDictObj.c: intent of making the latter list, plus

2006-10-31  Miguel Sofer  <msofer@users.sf.net>

* generic/tclBasic.c, generic/tcl.h, generic/tclInterp.c:
* generic/tclNamesp.c: removing the flag bit TCL_EVAL_NOREWRITE, the
last remnant of the callObjc/v fiasco. It is not needed, as it is now
always set and checked or'ed with TCL_EVAL_INVOKE.

2006-10-31  Pat Thoyts <patthoyts@users.sourceforge.net>

* win/rules.vc: Fix for [Bug 1582769] - options conflict with VC2003.

2006-10-31  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclBasic.c, generic/tclNamesp.c, generic/tclProc.c:
* generic/tclInt.h: Removed the callObjc and callObjv fields from the
Interp structure. They did not function correctly and made other parts
of the core amazingly complex, resulting in a substantive change to
[info level] behaviour. [Bug 1587618]
* library/clock.tcl: Removed use of [info level 0] for calculating the
command name as used by the user and replace with a literal. What's
there now is sucky, but at least appears to be right to most users.
* tests/namespace.test (namespace-42.7,namespace-47.1): Reverted
changes to these tests.
* tests/info.test (info-9.11,info-9.12): Added knownBug constraint
since these tests require a different behaviour of [info level] than
is possible because of other dependencies.

2006-10-30  Jeff Hobbs <jeffh@ActiveState.com>

* tools/tcltk-man2html.tcl (option-toc): handle any kind of options
defined toc section (needed for ttk docs)

2006-10-30  Miguel Sofer  <msofer@users.sf.net>

* generic/tclBasic.c (TEOVI): insured that the interp's callObjc/v
fields are restored after traces run, as they be spoiled. This was
causing a segfault in tcllib's profiler tests.

2006-10-30  Don Porter <dgp@users.sourceforge.net>

* generic/tclExecute.c (INST_MOD): Corrected improper testing of the
* tests/expr.test:    sign of bignums when applying Tcl's
division rules. Thanks to Peter Spjuth. [Bug 1585704]

2006-10-29  Miguel Sofer  <msofer@users.sf.net>

* generic/tclNamesp.c (EnsembleImplementationCmd):
* tests/namespace.test (47.7-8): reverted a wrong "optimisation" that
completely broke snit; added two tests.

2006-10-28  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclProc.c (ObjInterpProcEx, TclObjInterpProcCore): Split the
core of procedures to make it easier to build procedure-like code
without going through horrible contortions. This is the last critical
component to make advanced OO systems workable as simple loadable
extensions. TOIPC is now in the internal stub table.
(MakeProcError, MakeLambdaError): Refactored ProcessProcResultCode to
be simpler, some of which goes to TclObjInterpProcCore, and the rest
of which is now in these far simpler routines which just do errorInfo
stack generation for different types of procedure-like entity.
* tests/apply.test (apply-5.1): Updated to expect the more informative
form of message.

2006-10-27  Donal K. Fellows  <dkf@users.sf.net>

* generic/tclVar.c (HasLocalVars): New macro to make various bits and
pieces cleaner.

* generic/tclNamesp.c (TclSetNsPath): Expose SetNsPath() through
internal stubs table with semi-external name.

* generic/tclInt.h (CallFrame): Add a field for handling context data
for extensions (like object systems) that should be tied to a call
frame (and not a command or interpreter).

* generic/tclBasic.c (TclRenameCommand): Change to take CONST args;
they were only ever used in a constant way anyway, so this appears to
be a spot that was missed during TIP#27 work.

2006-10-26  Miguel Sofer  <msofer@users.sf.net>

* generic/tclProc.c (SetLambdaFromAny): minor change, eliminate
redundant call to Tcl_GetString (thanks aku).

* generic/tclInterp.c (ApplyObjCmd):
* generic/tclNamesp.c (EnsembleImplementationCmd): replaced ckalloc
(heap) with TclStackAlloc (execution stack).

2006-10-24  Miguel Sofer  <msofer@users.sf.net>

* tests/info.test (info-9.11-12): tests for [Bug 1577492]
* tests/apply.test (apply-4.3-5): tests for [Bug 1574835]

* generic/tclProc.c (ObjInterpProcEx): disable itcl hacks for calls
from ApplyObjCmd (islambda==1), as they mess apply's error messages
[Bug 1583266]

2006-10-23  Miguel Sofer  <msofer@users.sf.net>

* generic/tclProc.c (ApplyObjCmd): fix wrong#args for apply by using
the ensemble rewrite engine. [Bug 1574835]
* generic/tclInterp.c (AliasObjCmd): previous commit missed usage of

* generic/tclBasic.c (TclEvalObjvInternal): removed redundant check
for ensembles. [Bug 1577628]

* library/clock.tcl (format, scan): corrected wrong # args messages to
* tests/clock.test (3.1, 34.1):     make use of the new rewrite
capabilities of [info level]

* generic/tcl.h:    Lets TEOV update the iPtr->callObj[cv] new
* generic/tclBasic.c:    fields, except when the flag bit
* generic/tclInt.h:    TCL_EVAL_NOREWRITE is present. These values
* generic/tclNamesp.c:    are used by Tcl_PushCallFrame to initialise
* generic/tclProc.c:    the frame's obj[cv] fields, and allows
* tests/namespace.test:    [info level] to know and use ensemble
rewrites. [Bug 1577492]

The return value from [info level 0] on interp alias calls is changed:
previously returned the target command (including curried values), now
returns the source - what was actually called.

2006-10-23  Miguel Sofer  <msofer@users.sf.net>

* generic/tcl.h:    Modified the Tcl call stack so there is
* generic/tclBasic.c:    always a valid CallFrame, even at level 0
* generic/tclCmdIL.c:    [Patch 1577278]. Most of the changes
* generic/tclInt.h:    involve removing tests for a NULL
* generic/tclNamesp.c:    iPtr->(var)framePtr. There is now a
* generic/tclObj.c:    CallFrame pushed at interp creation with a
* generic/tclProc.c:    pointer to it stored in iPtr->rootFramePtr.
* generic/tclTrace.c:    A second unused field in Interp is
* generic/tclVar.c:    hijacked to enable further functionality,
currently unused (but with several FRQs depending on it).

Any user that includes tclInt.h and needs to determine if it is
running at level 0 should change (iPtr->varFramePtr == NULL) to
(iPtr->varFramePtr == iPtr->rootFramePtr).

2006-10-23  Don Porter <dgp@users.sourceforge.net>

2006-10-21  Miguel Sofer  <msofer@users.sf.net>

* generic/tcl.h, generic/tclHash.c: Tcl_FindHashEntry now calls
Tcl_CreateHashEntry with a newPtr set to NULL: this would have caused
a segfault previously and eliminates duplicated code. A macro has been
added to tcl.h (only used when TCL_PRESERVE_BINARY_COMPATABALITY is
not set - i.e., not by default).

2006-10-20  Reinhard Max  <max@tclers.tk>

* unix/configure.in: Added autodetection for OS-supplied timezone

2006-10-16  Don Porter <dgp@users.sourceforge.net>

* generic/tclPkg.c (ExactRequirement): Plugged memory leak. Also
changed Tcl_Alloc()/Tcl_Free() calls to ckalloc()/ckfree() for easier
memory debugging in the future. [Bug 1568373]

* library/tcltest/tcltest.tcl: Revise tcltest bump to 2.3a1.
* library/tcltest/pkgIndex.tcl: This permits more features to be
* unix/Makefile.in: added to tcltest before we reach version 2.3.0
* win/Makefile.in: best timed to match the release of Tcl 8.5.0.
* win/makefile.vc: This also serves as a demo of TIP 268 features

2006-10-13  Colin McCormack <coldstore@users.sf.net>

* win/tclWinFile.c: corrected erroneous attempt to protect against
NULL return from Tcl_FSGetNormalizedPath per [Bug 1548263] causing
[Bug 1575837].
* win/tclWinFile.c: alfredd supplied patch to fix [Bug 1575837]

2006-10-13  Daniel Steffen  <das@users.sourceforge.net>

* unix/tclUnixThrd.c (TclpThreadGetStackSize): on Darwin, use
* unix/tcl.m4: pthread_get_stacksize_np() API to get thread stack size
* unix/configure: autoconf-2.59
* unix/tclConfig.h.in: autoheader-2.59

2006-10-12  Miguel Sofer  <msofer@users.sf.net>

* generic/tclInterp.c (ApplyObjCmd):
* tests/interp.test (interp-14.5-10): made [interp alias] use the
ensemble rewrite machinery to produce better error messages [Bug

2006-10-12  David Gravereaux <davygrvy@pobox.com>

* win/nmakehlp.c: Replaced all wnsprintf() calls with snprintf().
wnsprintf was not in my shwlapi header file (VC++6)

2006-10-11  Don Porter <dgp@users.sourceforge.net>

* generic/tclPkg.c (Tcl_PackageRequireEx): Corrected crash when
argument version=NULL passed in.

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

* changes: Updates for 8.5a5 release.

* generic/tclNamespace.c (TclTeardownNamespace):  After the
commandPathSourceList of a namespace is cleared, set the
commandPathSourceList to NULL so we don't try to walk the list a
second time, possibly after it is freed. [Bug 1566526]
* tests/namespace.test (namespace-51.16): Added test.

2006-10-09  Miguel Sofer  <msofer@users.sf.net>

* doc/UpVar.3: brough the docs in accordance to the code. Ever since
8.0, Tcl_UpVar(2)? accepts TCL_NAMESPACE_ONLY as a flag value, and
var-3.4 tests for proper behaviour. The docs only allowed 0 and
TCL_GLOBAL_ONLY. [Bug 1574099]

2006-10-09  Miguel Sofer  <msofer@users.sf.net>

* tests/*.test: updated all tests to refer explicitly to the global
variables ::errorInfo, ::errorCode, ::env and ::tcl_platform: many
were relying on the alternative lookup in the global namespace, that
feature is tested specifically in namespace and variable tests.

The modified testfiles are: apply.test, basic.test, case.test,
cmdIL.test, cmdMZ.test, compExpr-old.test, error.test, eval.test,
event.test, expr.test, fileSystem.test, for.test, http.test, if.test,
incr-old.test, incr.test, interp.test, io.test, ioCmd.test, load.test,
misc.test, namespace.test, parse.test, parseOld.test, pkg.test,

* tests/binary.test:

2006-10-05  Andreas Kupries  <andreask@activestate.com>

* library/tm.tcl: Fixed bug in TIP #189 implementation, now allowing
'_' in module names.

2006-10-05  Jeff Hobbs <jeffh@ActiveState.com>

* library/http/http.tcl (http::geturl): only do geturl url rfc 3986
validity checking if $::http::strict is true (default true for 8.5).
[Bug 1560506]

* generic/tcl.h: note limitation on changing Tcl_UniChar size
* generic/tclEncoding.c (UtfToUnicodeProc, UnicodeToUtfProc):
* tests/encoding.test (encoding-16.1): fix alignment issues in
unicode <> utf conversion procs. [Bug 1122671]

2006-10-05  Miguel Sofer  <msofer@users.sf.net>

* generic/tclVar.c (Tcl_LappendObjCmd):
* tests/append.test(4.21-22): fix for longstanding [Bug 1570718],
lappending nothing to non-list. Reported by lvirden

2006-10-04  Kevin B. Kenny  <kennykb@acm.org>

* tzdata/: Olson's tzdata2006m.

2006-10-01  Kevin B. Kenny  <kennykb@acm.org>

* tests/clock.test (clock-49.2): Removed a locale dependency that
caused a spurious failure in the German locale. [Bug 1567956]

2006-10-01  Miguel Sofer  <msofer@users.sf.net>

* doc/Eval.3 (TclEvalObjv): added note on refCount management for the
elements of objv. [Bug 730244]

2006-10-01  Pat Thoyts <patthoyts@users.sourceforge.net>

* win/tclWinFile.c: Handle possible missing define.

* win/tclWinFile.c (TclpUtime): [Bug 1420432] file mtime fails for
* tests/cmdAH.test: directories on windows

* tests/winFile.test: Handle Msys environment a little differently in
getuser function. [Bug 1567956]

2006-09-30  Miguel Sofer  <msofer@users.sf.net>

* generic/tclUtil.c (Tcl_SplitList): optimisation, [Patch 1344747] by

* generic/tclInt.decls:
* generic/tclInt.h:
* generic/tclIntDecls.h:
* generic/tclObj.c:
* generic/tclStubInit.c: added an internal function TclObjBeingDeleted
to provide info as to the reason for the loss of an internal rep. [FR

* generic/tclCompile.c:
* generic/tclHistory.c:
* generic/tclInt.h:
* generic/tclProc.c: made Tcl_RecordAndEvalObj not call "history" if
it has been redefined to an empty proc, in order to reduce the noise
when debugging [FR 1190441]. Moved TclCompileNoOp from tclProc.c to

2006-09-28  Andreas Kupries  <andreask@activestate.com>

* generic/tclPkg.c (CompareVersions): Bugfix. Check string lengths
* tests/pkg.test: before comparison. The shorter string is the smaller
number. Added testcases as well. Interestingly all existing test cases
for vcompare compared numbers of the same length with each other. [Bug

2006-09-28  Miguel Sofer  <msofer@users.sf.net>

* generic/tclIO.c (Tcl_GetsObj): added two test'n'panic guards for
possible NULL derefs, [Bug 1566382] and coverity #33.

2006-09-27  Don Porter <dgp@users.sourceforge.net>

* generic/tclExecute.c: Corrected error in INST_LSHIFT in the
* tests/expr.test: calculation done to determine whether a shift
in the (long int) type is possible. The calculation had literal value
"1" where it needed a value "1L" to compute the correct result. Error
detected via testing with the math::bigfloat package [Bug 1567222]

* generic/tclPkg.c (CompareVersion): Flatten strcmp() results to
{-1, 0, 1} to match expectations of CompareVersion() callers.

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

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

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

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

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

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

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

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

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

* doc/Encoding.3: Added covariant 'const' qualifier for the
* generic/tcl.decls: Tcl_EncodingType argument to
* generic/tclEncoding.c: Tcl_CreateEncoding. [Further TIP#27 work.]
* generic/tclDecls.h: Reran 'make genstubs'.

2006-09-26  Pat Thoyts <patthoyts@users.sourceforge.net>

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

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

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

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

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

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

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

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

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

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

* generic/tclNotify.c (Tcl_DeleteEvents): Simplified the code in hopes
of making the invariants clearer and proving to Coverity that the
event queue memory is managed correctly.

2006-09-25  Donal K. Fellows  <dkf@users.sf.net>

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* library/http/http.tcl:      Change " " -> "+" url encoding mapping

HP-UX 11.00 and beyond as having mt-safe implementations of the
gethost functions.
* unix/configure: Regenerated, using autoconf 2.59

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

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

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

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

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

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

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

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

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

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

* unix/Makefile.in: Bumped msgcat version to 1.4.2 to be

2006-09-11  Don Porter <dgp@users.sourceforge.net>

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

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

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

* doc/tcltest.n: Bump to version tcltest 2.3.0 to

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

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

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

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

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

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

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

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

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

* unix/configure: Regenerated with autoconf V2.59

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

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

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

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

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

* unix/tclUnixChan.c: Rewritten MT-safe wrappers to return ptrs to

some library calls.

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

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

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

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

* doc/package.n: correct package example

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* generic/tclIOUtil.c: Added test for NULL return from

2006-08-28  Don Porter <dgp@users.sourceforge.net>

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

iterate over an invalid dictionary. [Bug 1531184]

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* macosx/tclMacOSXFCmd.c (TclMacOSXCopyFileAttributes):    add support
* macosx/tclMacOSXNotify.c (Tcl_InitNotifier):    for weakly
* unix/tclUnixInit.c (Tcl_GetEncodingNameFromEnvironment): importing
symbols not available on OSX 10.2 or 10.3, enables binaires built on
later OSX versions to run on earlier ones.
* macosx/Tcl.xcodeproj/project.pbxproj: enable weak-linking; turn on
extra warnings.
* macosx/README: document how to enable weak-linking; cleanup.
* unix/tclUnixPort.h: add support for weak-linking; conditionalize
AvailabilityMacros.h inclusion; only disable realpath on 10.2 or
earlier when threads are enabled.
* unix/tclLoadDyld.c (TclpLoadMemoryGetBuffer): change runtime Darwin
* unix/tclUnixInit.c (TclpInitPlatform): release check to use
global initialized
* 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; clean up
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/tclStrToD.c (TclParseNumber):
* generic/tclStringObj.c (TclAppendFormattedObjs):
* unix/tclLoadDyld.c (TclpLoadMemory):
* unix/tclUnixPipe.c (TclpCreateProcess): fix signed-with-unsigned
comparison and other warnings from gcc4 -Wextra.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* generic/tclStrToD.c: Added code to support the "middle endian"
floating point format used in the Nokia N770's software-based floating
point. Thanks to Bruce Johnson for reporting this bug, originally on

spaces (*not* whitespace). [Bug 1376892]

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

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

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

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

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

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

same manner as any other key. [Bug 1464039]

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

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

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

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

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

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

* changes: Updates for another RC.

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

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

* 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]
* unix/tclUnixFile.c: and [file attributes]; fix globbing for
hidden files with pattern==NULL arg. [Bug 823329]
* generic/tclIntPlatDecls.h:
* generic/tclStubInit.c: make genstubs

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* doc/clock.n: Removed double-quotes around section title NAME; not
* 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. Thanks to Julian
Noble. [Bug 1448251]

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* tests/compile.test:
* tests/incr-old.test:
* tests/incr.test:
* tests/set.test:

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

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

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

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


* doc/Encoding.3: New subcommand [encoding dirs].
* doc/encoding.n: New routine Tcl_GetEncodingNameFromEnvironment
* generic/tcl.decls: Made public:
* generic/tclBasic.c: TclGetEncodingFromObj
* generic/tclCmdAH.c: -> Tcl_GetEncodingFromObj
* generic/tclEncoding.c:TclGetEncodingSearchPath
* generic/tclInt.decls: -> Tcl_GetEncodingSearchPath
* generic/tclInt.h: TclSetEncodingSearchPath
* generic/tclTest.c: -> Tcl_SetEncodingSearchPath

missing work in error reporting

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


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


* doc/Namespace.3: New command [namespace unknown]. New public C
* doc/namespace.n: routines Tcl_(Get|Set)NamespaceUnknownHandler.
* doc/unknown.n: [Patch 958222]

* generic/tclVar.c:
* tests/namespace.test:
* tests/upvar.test:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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