Tcl Source Code

Artifact Content
Bounty program for improvements to Tcl and certain Tcl packages.

Artifact 74fc80ee09602f1a9d0ed83e0f4a1b34026c1a57:

Starting in early 2011, Tcl source code has been under the management of
fossil, hosted at .  Fossil presents a "Timeline"
view of changes made that is superior in every way to a hand edited log file.
Because of this, many Tcl developers are now out of the habit of maintaining
this log file.  You may still find useful things in it, but the Timeline is
a better first place to look now.

2013-09-17  Donal Fellows  <[email protected]>

	* generic/tclBinary.c (BinaryEncodeUu, BinaryDecodeUu): [Bug 2152292]:
	Corrected implementation of the core of uuencode handling so that the
	line length processing is correctly applied.
	Existing code that was using the old versions and working around the
	limitations will now need to do far less. The -maxlen option now has
	strict limits on the range of supported lengths; this is a limitation
	of the format itself.

2013-09-09  Donal Fellows  <[email protected]>

	* generic/tclOOMethod.c (CloneProcedureMethod): [Bug 3609693]: Strip

	last decoded byte.

2013-08-03  Donal Fellows  <[email protected]>

	* library/auto.tcl: [Patch 3611643]: Allow TclOO classes to be found
	by the autoloading mechanism.

2013-08-02  Donal Fellows  <[email protected]>

	* generic/tclOODefineCmds.c (ClassSuperSet): Bug [9d61624b3d]: Stop
	crashes when emptying the superclass slot, even when doing elaborate
	things with metaclasses.

2013-08-01  Harald Oehlmann  <[email protected]>

	* tclUnixNotify.c (Tcl_InitNotifier): Bug [a0bc856dcd]: Start notifier
	thread again if we were forked, to solve Rivet bug 55153.

2013-07-05  Kevin B. Kenny  <[email protected]>

	[:cntrl:] should contain \u0000 - \u001f

2013-06-09  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmdsSZ.c (TclCompileTryCmd): [Bug 779d38b996]:
	Rewrote the [try] compiler to generate better code in some cases and
	to behave correctly in others; when an error happens during the
	processing of an exception-trap clause or a finally clause, the
	*original* return options are now captured in a -during option, even
	when fully compiled.

2013-06-05  Donal K. Fellows  <[email protected]>

	* generic/tclExecute.c (INST_EXPAND_DROP): [Bugs 2835313, 3614226]:
	New opcode to allow resetting the stack to get rid of an expansion,
	restoring the stack to a known state in the process.
	* generic/tclCompile.c, generic/tclCompCmds.c: Adjusted the compilers
	for [break] and [continue] to get stack cleanup right in the majority
	of cases.
	* tests/for.test (for-7.*): Set of tests for these evil cases.

2013-06-04  Jan Nijtmans  <[email protected]>

	* unix/tcl.m4: Eliminate NO_VIZ macro as current zlib uses HAVE_HIDDEN
	instead. One more last-moment fix for FreeBSD by Pietro Cerutti

2013-06-03  Miguel Sofer  <[email protected]>

	* generic/tclExecute.c: fix for perf bug detected by Kieran
	diagnosed by dgp to be a close relative of [Bug 781585], which was
	fixed by commit	[f46fb50cb3]. This bug was introduced by myself in
	commit [cbfe055d8c].

2013-06-03  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c (TclCompileBreakCmd, TclCompileContinueCmd):
	Added code to allow [break] and [continue] to be issued as a jump (in
	the most common cases) rather than using the more expensive exception
	processing path in the bytecode engine. [Bug 3614226]: Partial fix for
	the issues relating to cleaning up the stack when dealing with [break]
	and [continue].

2013-05-27 Harald Oehlmann  <[email protected]>

	* library/msgcat/msgcat.tcl: [Bug 3036566]: Also get locale from

	uses of strcasecmp with a proper UTF-8-aware version. Affects both
	[lsearch -nocase] and [lsort -nocase].

2013-05-22  Donal K. Fellows  <[email protected]>

	* doc/file.n: [Bug 3613671]: Added note to portability section on the
	fact that [file owned] does not produce useful results on Windows.

2013-05-20  Donal K. Fellows  <[email protected]>

	* unix/tclUnixFCmd.c (DefaultTempDir): [Bug 3613567]: Corrected logic
	for checking return code of access() system call, which was inverted.

2013-05-19  Jan Nijtmans  <[email protected]>

	* unix/tcl.m4:     Fix for FreeBSD, and remove support for older
	* unix/configure:  FreeBSD versions. Patch by Pietro Cerutti.

2013-05-18  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmdsGR.c: Split tclCompCmds.c again to keep size of
	code down.

2013-05-16  Jan Nijtmans  <[email protected]>

	* generic/tclBasic.c: Add panic in order to detect incompatible
	mingw32 sys/stat.h and sys/time.h headers.

2013-05-13  Jan Nijtmans  <[email protected]>

	* compat/zlib/*: Upgrade to zlib 1.2.8

2013-05-10  Donal K. Fellows  <[email protected]>

	Optimizations and general bytecode generation improvements.
	* generic/tclCompCmds.c (TclCompileAppendCmd, TclCompileLappendCmd):
	(TclCompileReturnCmd): Make these generate bytecode in more cases.
	(TclCompileListCmd): Make this able to push a literal when it can.
	* generic/tclCompile.c (TclSetByteCodeFromAny, PeepholeOptimize):
	Added checks to see if we can apply some simple cross-command-boundary
	optimizations, and defined a small number of such optimizations.
	(TclCompileScript): Added the special ability to compile the list
	command with expansion ([list {*}blah]) into bytecode that does not
	call an external command.

2013-05-06  Jan Nijtmans  <[email protected]>

	* generic/tclStubInit.c: Add support for Cygwin64, which has a 64-bit
	* generic/tclDecls.h: "long" type. Binary compatibility with win64
	requires that all stub entries use 32-bit long's, therefore the need
	for various wrapper functions/macros. For Tcl 9 a better solution is
	needed, but that cannot be done without introducing binary

2013-04-30  Andreas Kupries  <[email protected]>

	* library/platform/platform.tcl (::platform::LibcVersion):
	* library/platform/pkgIndex.tcl: Followup to the 2013-01-30 change.

	when the list of things to set is a literal.

2013-04-25  Jan Nijtmans  <[email protected]>

	* generic/tclDecls.h: Implement Tcl_NewBooleanObj, Tcl_DbNewBooleanObj
	and Tcl_SetBooleanObj as macros using Tcl_NewIntObj, Tcl_DbNewLongObj
	and Tcl_SetIntObj. Starting with Tcl 8.5, this is exactly the same, it
	only eliminates code duplication.
	* generic/tclInt.h: Eliminate use of NO_WIDE_TYPE everywhere: It's
	exactly the same as TCL_WIDE_INT_IS_LONG

2013-04-19  Jan Nijtmans  <[email protected]>

	* generic/tclDecls.h: Implement many Tcl_*Var* functions and
	Tcl_GetIndexFromObj as (faster/stack-saving) macros around resp their
	Tcl_*Var*2 equivalent and Tcl_GetIndexFromObjStruct.

2013-04-12  Jan Nijtmans  <[email protected]>

	* generic/tclDecls.h: Implement Tcl_Pkg* functions as
	(faster/stack-saving) macros around Tcl_Pkg*Ex functions.

2013-04-08  Don Porter  <[email protected]>

	* generic/regc_color.c:	[Bug 3610026]: Stop crash when the number of
	* generic/regerrs.h:	"colors" in a regular expression overflows a

	* generic/regguts.h:	the report and the patch.
	* tests/regexp.test:

2013-04-04  Reinhard Max  <[email protected]>

	* generic/tclZlib.c (ZlibTransformOutput): [Bug 3603553]: Ensure that
	data gets written to the underlying stream by compressing transforms
	when the amount of data to be written is one buffer's-worth; problem
	was particularly likely to occur when compressing large quantities of
	not-very-compressible data. Many thanks to Piera Poggio (vampiera) for

2013-02-09  Donal K. Fellows  <[email protected]>

	* generic/tclOOBasic.c (TclOO_Object_VarName): [Bug 3603695]: Change
	the way that the 'varname' method is implemented so that there are no
	longer problems with interactions due to the resolver. Thanks to
	Taylor Venable <[email protected]> for identifying the problem.

2013-02-08  Donal K. Fellows  <[email protected]>

	* generic/regc_nfa.c (duptraverse): [Bug 3603557]: Increase the
	maximum depth of recursion used when duplicating an automaton in
	response to encountering a "wild" RE that hit the previous limit.
	Allow the limit (DUPTRAVERSE_MAX_DEPTH) to be set by defining its

	present on the system.

2013-02-05  Donal K. Fellows  <[email protected]>

	* generic/tclLoadNone.c (TclpLoadMemory): [Bug 3433012]: Added dummy
	version of this function to use in the event that a platform thinks it

	* library/http/http.tcl (http::geturl): [Bug 2911139]: Do not do vwait
	for connect to avoid reentrancy problems (except when operating
	without a -command option). Internally, this means that all sockets
	created by the http package will always be operated in asynchronous

2013-01-21  Jan Nijtmans  <[email protected]>

	* generic/tclInt.decls: Put back Tcl[GS]etStartupScript(Path|FileName)
	in private stub table, so extensions using this (like Tk 8.4) will
	continue to work in all Tcl 8.x versions. Extensions using this
	still cannot be compiled against Tcl 8.6 headers.

2013-01-18  Jan Nijtmans  <[email protected]>

2013-01-16  Donal K. Fellows  <[email protected]>

	* generic/tclZlib.c (TclZlibInit): [Bug 3601086]: Register the config
	info in the iso8859-1 encoding as that is guaranteed to be present.

2013-01-16  Jan Nijtmans  <[email protected]>

	*   Allow win32 build with -DTCL_NO_DEPRECATED, just as
	* generic/tcl.h: in 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  <[email protected]>

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

2013-01-14  Jan Nijtmans  <[email protected]>

	* generic/tclInt.decls: Put back Tcl_[GS]etStartupScript in internal
	stub table, so extensions using this, compiled against 8.5 headers
	still run in Tcl 8.6.

2013-01-13  Alexandre Ferrieux  <[email protected]>

	* doc/fileevent.n: [Bug 3436609]: Clarify readable fileevent "false
	positives" in the case of multibyte encodings/transforms.

2013-01-13  Jan Nijtmans  <[email protected]>

	* generic/tclIntDecls.h: If TCL_NO_DEPRECATED is defined, make sure
	that TIP #139 functions all are taken from the public stub table, even
	if the inclusion is through tclInt.h.

2013-01-12  Jan Nijtmans  <[email protected]>

	* generic/tclInt.decls: Put back TclBackgroundException in internal
	stub table, so extensions using this, compiled against 8.5 headers
	still run in Tcl 8.6.

2013-01-09  Jan Nijtmans  <[email protected]>

	* library/http/http.tcl: [Bug 3599395]: http assumes status line is a
	proper Tcl list.

2013-01-08  Jan Nijtmans  <[email protected]>

	* win/tclWinFile.c: [Bug 3092089]: [file normalize] can remove path
	components.	[Bug 3587096]: win vista/7: "can't find init.tcl" when
	called via junction without folder list access.

2013-01-07  Jan Nijtmans  <[email protected]>

	* generic/tclOOStubLib.c: Restrict the stub library to only use
	* generic/tclTomMathStubLib.c: Tcl_PkgRequireEx, Tcl_ResetResult and
	Tcl_AppendResult, not any other function. This puts least restrictions
	on eventual Tcl 9 stubs re-organization, and it works on the widest
	range of Tcl versions.

2013-01-06  Jan Nijtmans  <[email protected]>

	* library/http/http.tcl: Don't depend on Spencer-specific regexp
	* tests/env.test: syntax (/u and /U) any more in unrelated places.

	Bump http package to 2.8.6.

2013-01-04  Donal K. Fellows  <[email protected]>

	* generic/tclEnsemble.c (CompileBasicNArgCommand): Added very simple
	compiler (which just compiles to a normal invoke of the implementation
	command) for many ensemble subcommands where we can prove that there
	is no way for scripts to detect the difference even through error
	handling or [info level]/[info frame]. This improves the code produced
	from some ensembles (e.g., [info], [string]) to the point where the
	ensemble is now not normally seen at the bytecode level at all.

	* generic/tclInt.h:      Insure that PURIFY builds cannot exploit the

2013-01-03  Donal K. Fellows  <[email protected]>

	* doc/fconfigure.n, doc/CrtChannel.3: Updated to reflect the fact that

	Bron on the Tcler's Chat.

	* generic/tclExecute.c (TEBCresume:INST_INVOKE_REPLACE):
	* generic/tclEnsemble.c (TclCompileEnsemble): Added new mechanism to
	allow for more efficient dispatch of non-bytecode-compiled subcommands
	of bytecode-compiled ensembles. This can provide substantial speed
	benefits in some cases.

	* 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 2.8.5.

2012-11-05  Donal K. Fellows  <[email protected]>

	Added bytecode compilation of many Tcl commands. Some of these are
	total compilations and some are only partial (i.e., only compile in
	some cases). The (sub-)commands affected are:
	* array: exists, set, unset
	* dict: create, exists, merge
	* format: (simple cases only)
	* info: commands, coroutine, level, object
	* info object: class, isa object, namespace
	* namespace: current, code, qualifiers, tail, which
	* regsub: (only cases convertable to simple [string map])
	* self: (only no-argument and [self object] cases)
	* string: first, last, map, range
	* tailcall:
	* yield:

	[This was work originally done on the 'dkf-compile-misc-info' branch.]

	Align the [string trim] and [string is space] commands, such that
	[string trim] by default trims all characters for which [string is
	space] returns 1, augmented with the NUL character.

	* generic/tclUtf.c: Add NEL, BOM and two more characters to [string is
	* generic/tclCmdMZ.c: Modify [string trim] for Unicode modifications.
	* generic/regc_locale.c: Regexp engine must match [string is space]
	* doc/string.n
	* tests/string.test
	Code that relied on characters not previously trimmed being not
	removed will notice a difference; it is believed that this is rare,
	but a workaround to get the behavior in Tcl 8.5 is to use " \t\n\r" as
	an explicit trim set.

2012-10-16  Donal K. Fellows  <[email protected]>


	New commands for applying a transformation to the elements of a list
	to produce another list (the [lmap] command) and to the mappings of a
	dictionary to produce another dictionary (the [dict map] command). In
	both cases, a [continue] will cause the skipping of an element/pair,
	and a [break] will terminate the construction early and successfully.

	* generic/tclCmdAH.c (Tcl_LmapObjCmd, TclNRLmapCmd): Implementation of
	the new [lmap] command, based on (and sharing much of) [foreach].
	* generic/tclDictObj.c (DictMapNRCmd): Implementation of the new [dict
	map] subcommand, based on (and sharing much of) [dict for].
	* generic/tclCompCmds.c (TclCompileLmapCmd, TclCompileDictMapCmd):
	Compilation engines for [lmap] and [dict map].


	* generic/tclZlib.c: Allow the specification of a compression
	dictionary (a binary blob used to seed the compression engine) in both
	streams and channel transformations. Also some reorganization to allow
	for getting gzip header dictionaries and controlling buffering levels
	in channel transformations (allowing a trade-off between formal
	correctness and speed).
	(Tcl_ZlibStreamSetCompressionDictionary): New C API to allow setting
	the compression dictionary without using a Tcl script.

	The unknown method handler now may be asked to deal with the case

2011-11-20  Joe Mistachkin  <[email protected]>

	* tests/thread.test: Remove unnecessary [after] calls from the thread
	tests.  Make error message matching more robust for tests that may
	have built-in race conditions.  Test thread-7.26 must first unset all
	thread testing related variables.  Revise results of the thread-7.28
	through thread-7.31 tests to account for the fact they are canceled
	via a script sent to the thread asynchronously, which then impacts the
	error message handling.  Attempt to manually drain the event queue for
	the main thread after joining the test thread to make sure no stray
	events are processed at the wrong time on the main thread.  Revise all
	the synchronization and comparison semantics related to the thread id
	and error message.

2011-11-18  Joe Mistachkin  <[email protected]>

	* tests/thread.test: Remove all use of thread::release from the thread
	7.x tests, replacing it with a script that can easily cause "stuck"
	threads to self-destruct for those test cases that require it.  Also,
	make the error message handling far more robust by keeping track of
	every asynchronous error.

2011-11-17  Joe Mistachkin  <[email protected]>

	* tests/thread.test: Refactor all the remaining thread-7.x tests that
	were using [testthread].  Note that this test file now requires the
	very latest version of the Thread package to pass all tests.  In
	addition, the thread-7.18 and thread-7.19 tests have been flagged as
	knownBug because they cannot pass without modifications to the [expr]
	command, persuant to TIP #392.

	* tests/thread.test:	Stop using the deprecated thread management
	commands of the tcltest package.  The test suite ought to provide
	these tools for itself.  They do not belong in a testing harness.

2011-09-20  Don Porter  <[email protected]>

	* generic/tclIORChan.c: Re-using the "interp" field to signal a dead
	channel (via NULL value) interfered with conditional cleanup tasks
	testing for "the right interp". Added a new field "dead" to perform
	the dead channel signalling task so the corrupted logic is avoided.

	* generic/tclIORTrans.c: Revised ReflectClose() and
	FreeReflectedTransform() so that we stop leaking ReflectedTransforms,
	yet free all Tcl_Obj values in the same thread that alloced them.

2011-09-19  Don Porter  <[email protected]>

	* tests/ioTrans.test:	Conversion from [testthread] to Thread package
	stops most memory leaks.

	* tests/thread.test:	Plug most memory leaks in thread.test.
	Constrain the rest to be skipped during `make valgrind'.  Tests using
	the [testthread cancel] testing command are leaky.  Corrections wait
	for either addition of [thread::cancel] to the Thread package, or
	improvements to the [testthread] testing command to make leak-free
	versions of these tests possible.

	* generic/tclCmdMZ.c:	Revised TclFindElement() interface. The final
	* generic/tclDictObj.c:	argument had been bracePtr, the address of a
	* generic/tclListObj.c:	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

	For any callers calling in via the internal stubs table who really do

	* generic/tclCmdMZ.c:	New internal utility routines TclTrimLeft()

2011-03-20  Miguel Sofer  <[email protected]>

	* generic/tclThreadAlloc.c: Imported HAVE_FAST_TSD support from

	in an effort to silence a MSVC warning reported by Ashok P. Nadkarni.
	Unable to test, since both forms work on my machine in VC2005, 2008,
	2010, in both release and debug builds.
	* tests/tclTest.c (TestdstringCmd): Restored MSVC buildability broken

2011-03-12  Donal K. Fellows  <[email protected]>

	* generic/tcl.h (ckalloc,ckfree,ckrealloc): Moved casts into these
	macro so that they work with VOID* (which is a void* on all platforms
	which Tcl actually builds on) and unsigned int for the length
	parameters, removing the need for MANY casts across the rest of Tcl.
	Note that this is a strict source-level-only change, so size_t cannot
	be used (would break binary compatibility on 64-bit platforms).

	consequence of making it vital for Tcl code that wishes to work with
	namespaces to _not_ delete the ::tcl namespace.

	* library/tcltest/tcltest.tcl (loadIntoSlaveInterpreter): Added this
	command to handle connecting tcltest to a slave interpreter. This adds
	in the hook (inside the tcltest namespace) that allows the tests run
	in the child interpreter to be reported as part of the main sequence
	of test results. Bumped version of tcltest to 2.3.3.

	that forward branches can use jump1 (jumpTrue1, jumpFalse1). Added
	test cases that the forward branches will expand to jump4, jumpTrue4,
	jumpFalse4 when needed.

	* generic/tclCompCmds.c (TclCompileDictForCmd): Update the compilation
	* generic/tclCompile.c (tclInstructionTable):	of [dict for] so that
	* generic/tclExecute.c (TEBCresume):		it no longer makes any
	use of INST_DICT_DONE now that's not needed, and make it clearer in
	the implementation of the instruction that it's just a deprecated form
	of unset operation. Followup to my commit of 2010-10-16.

2010-10-19  Donal K. Fellows  <[email protected]>

	* generic/tclZlib.c (Tcl_ZlibStreamGet): [Bug 3081008]: Ensure that
	when a bytearray gets its internals entangled with zlib for more than
	a passing moment, that bytearray will never be shimmered away. This
	increases the amount of copying but is simple to get right, which is a
	reasonable trade-off.

	* generic/tclStringObj.c (Tcl_AppendObjToObj): Added some special
	cases so that most of the time when you build up a bytearray by
	appending, it actually ends up being a bytearray rather than
	shimmering back and forth to string.

	* tests/http11.test (check_crc): Use a simpler way to express the
	functionality of this procedure.

	* generic/tclZlib.c: Purge code that wrote to the object returned by

	* tests/remote.tcl:	randomized ports to reduce interference with
				tests running in parallel or other services on
				the machine.

2010-09-28  Kevin B. Kenny  <[email protected]>


	* tests/assemble.test: Added more "white box" tests.
	* generic/tclAssembly.c: Added the error checking and reporting
	for undefined labels. Revised code so that no pointers into the
	bytecode sequence are held (because the sequence can move!),
	that no Tcl_HashEntry pointers are held (because the hash table
	doesn't guarantee their stability!) and to eliminate the BBHash
	table, which is merely additional information indexed by jump
	labels and can just as easily be held in the 'label' structure.
	Renamed shared structures to CamelCase, and renamed 'label' to
	JumpLabel because other types of labels may eventually be possible.

2010-09-27  Kevin B. Kenny  <[email protected]>


	* tests/assemble.test: Added more "white box" tests.
	* generic/tclAssembly.c: Fixed bugs exposed by the new tests.
	(a) [eval] and [expr] had incorrect stack balance computed if
	the arg was not a simple word. (b) [concat] accepted a negative
	operand count. (c) [invoke] accepted a zero or negative operand
	count. (d) more misspelt error messages.
	Also replaced a funky NRCallTEBC with the new call
	TclNRExecuteByteCode, necessitated by a merge with changes on the

2010-09-26  Miguel Sofer  <[email protected]>

	* generic/tclBasic.c:    [Patch 3072080] (minus the itcl
	* generic/tclCmdIL.c:    update): a saner NRE.
	* generic/tclCompExpr.c:

	* tests/assemble.test:	Added many new tests moving toward a more
	comprehensive test suite for the assembler.
	* generic/tclAssembly.c:	Fixed bugs exposed by the new tests:
	(a) [bitnot] and [not] had incorrect operand counts. (b)
	INST_CONCAT cannot concatenate zero objects. (c) misspelt error
	messages. (d) the "assembly code" internal representation lacked
	a duplicator, which caused double-frees of the Bytecode object
	if assembly code ever was duplicated.

2010-09-25  Kevin B. Kenny   <[email protected]>


	* generic/tclAssembly.c:	Massive refactoring of the assembler
	* generic/tclAssembly.h:	to use a Tcl-like syntax (and use
	* tests/assemble.test:		Tcl_ParseCommand to parse it). The
	* tests/assemble1.bench:	refactoring also ensures that
	Tcl_Tokens in the assembler have string ranges inside the source
	code, which allows for [eval] and [expr] assembler directives
	that simply call TclCompileScript and TclCompileExpr recursively.

2010-09-24  Jeff Hobbs  <[email protected]>

	* tests/stringComp.test: improved string eq/cmp test coverage
	* generic/tclExecute.c (TclExecuteByteCode): merge INST_STR_CMP and

	* generic/tclStubLib.c:	Remove presence of tclTomMathStubsPtr here.
	* generic/tclTest.c:	Test that tommath stubs are present in stub

2010-03-05  Donal K. Fellows  <[email protected]>

	* generic/tclIORTrans.c (ForwardProc): [Bug 2964425]: When cleaning
	the stables, it is sometimes necessary to do more than the minimum. In
	this case, rationalizing the variables for a forwarded limit? method
	required removing an extra Tcl_DecrRefCount too.

	* generic/tclOO.h, generic/tclOOInt.h: [Patch 2961556]: Change TclOO
	to use the same style of function typedefs as Tcl, as this is about
	the last chance to get this right.

	Source code that uses function typedefs from TclOO will need to update
	variables and argument definitions so that pointers to the function
	values are used instead. Binary compatibility is not affected.

	* generic/*.c, generic/tclInt.h, unix/*.c, macosx/*.c: Applied results
	of doing a Code Audit. Principal changes:
	  * Use do { ... } while (0) in macros
	  * Avoid shadowing one local variable with another
	  * Use clearer ';' instead of ';' where result not
	    required (i.e., semantically equivalent); clarity is increased
	    because it is bar that is incremented, not foo.
	  * Follow Engineering Manual rules on spacing and declarations

2010-03-04  Donal K. Fellows  <[email protected]>

	* generic/tclOO.c (ObjectRenamedTrace): [Bug 2962664]: Add special
	handling so that when the class of classes is deleted, so is the class
	of objects. Immediately.

	* generic/tclOOInt.h (ROOT_CLASS): Add new flag for specially marking
	the root class. Simpler and more robust than the previous technique.

2010-03-04  Jan Nijtmans  <[email protected]>

	* generic/tclGetDate.y:    3 unnecessary MODULE_SCOPE
	* generic/tclDate.c:       symbols

2010-03-03  Andreas Kupries <[email protected]>

	* doc/refchan.n: Followup to ChangeLog entry 2009-10-07
	(generic/tclIORChan.c). Fixed the documentation to explain that errno
	numbers are operating system dependent, and reworked the associated

2010-03-02  Jan Nijtmans  <[email protected]>

	* unix/tcl.m4:     [FRQ 2959069]: Support for -fvisibility=hidden
	* unix/configure   (regenerated with autoconf-2.59)

2010-03-01  Alexandre Ferrieux  <[email protected]>

	* unix/tclUnixSock.c: Refrain from a possibly lengthy reverse-DNS
	lookup on when calling [fconfigure -sockname] on an
	universally-bound (default) server socket.

	* generic/tclIndexObj.c: fix [AT 86258]: special-casing of empty
	tables when generating error messages for [::tcl::prefix match].

2010-02-28  Donal K. Fellows  <[email protected]>

	* generic/tclCmdIL.c: More additions of {TCL LOOKUP} error-code
	generation to various subcommands of [info] as part of long-term
	project to classify all Tcl's generated errors.

2010-02-28  Jan Nijtmans  <[email protected]>

	* generic/tclStubInit.c: [Bug 2959713]: Link error with gcc 4.1

2010-02-27  Donal K. Fellows  <[email protected]>

	* generic/tclCmdMZ.c (StringFirstCmd, StringLastCmd): [Bug 2960021]:
	Only search for the needle in the haystack when the needle isn't
	larger than the haystack. Prevents an odd crash from sometimes
	happening when things get mixed up (a common programming error).

	* generic/tclMain.c (Tcl_Main): [Bug 801429]: Factor out the holding
	of the client-installed main loop function into thread-specific data.

	Code that previously tried to set the main loop from another thread
	will now fail. On the other hand, there is a fairly high probability
	that such programs would have been failing before due to the lack of
	any kind of inter-thread memory barriers guarding accesses to this
	part of Tcl's state.

2010-02-26  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c:   Split this file into two pieces to make it
	* generic/tclCompCmdsSZ.c: easier to work with. It's still two very
				   long files even after the split.

2010-02-26  Reinhard Max  <[email protected]>

	* doc/safe.n: Name the installed file after the command it documents.
	Use "Safe Tcl" instead of the "Safe Base", "Safe Tcl" mixture.

2010-02-26  Donal K. Fellows  <[email protected]>

	* unix/ (NATIVE_TCLSH): Added this variable to allow for
	better control of what tclsh to use for various scripts when doing
	cross compiling. An imperfect solution, but works.

	* unix/installManPage: Remap non-alphanumeric sequences in filenames
	to single underscores (especially colons).

2010-02-26  Pat Thoyts  <[email protected]>

	* tests/zlib.test: Add tests for [Bug 2818131] which was crashing with
	mismatched zlib algorithms used in combination with gets. This issue
	has been fixed by Andreas's last commit.

2010-02-25  Jan Nijtmans  <[email protected]>

	* generic/tclHash.c:	[FRQ 2958832]: Further speed-up of the

	* generic/tclObj.c:
	* generic/tclCkalloc.c:	Eliminate various unnecessary (ClientData)

	* generic/tclDictObj.c (SetDictFromAny): Prevent the list<->dict
	* generic/tclListObj.c (SetListFromAny): conversion code from taking
	too many liberties. Stops loss of duplicate keys in some scenarios.
	Many thanks to Jean-Claude Wippler for finding this.

	* generic/tclExecute.c (TclExecuteByteCode): Reduce ifdef-fery and
	size of activation record. More variables shared across instructions
	than before.

	* doc/socket.n: [Bug 2957688]: Clarified that [socket -server] works
	with a command prefix. Extended example to show this in action.

2010-02-22  Andreas Kupries  <[email protected]>

	* generic/tclZlib.c (ZlibTransformInput): [Bug 2762041]: Added a hack
	to work around the general problem, early EOF recognition based on the
	base-channel, instead of the data we have ready for reading in the
	transform. Long-term we need a proper general fix (likely tracking EOF
	on each level of the channel stack), with attendant complexity.
	Furthermore, Z_BUF_ERROR can be ignored, and must be when feeding the
	zlib code with single characters.

2010-02-22  Jan Nijtmans  <[email protected]>

	* unix/tclUnixPort.h:   Remove unnecessary EXTERN's, which already are
	                        in the global stub table.

	* generic/tclGetDate.y:
	* generic/regc_lex.c:

	* generic/tclStubLib.c:
	* generic/tclBasic.c:   Fix [Bug 2954959] expr abs(0.0) is -0.0
	* tests/expr.test:

2010-02-20  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c (TclCompileStringLenCmd): Make [string length]
	of a constant string be handled better (i.e., handle backslashes too).

2010-02-19  Stuart Cassoff  <[email protected]>

	* tcl.m4: Correct compiler/linker flags for threaded builds on
	* configure: (regenerated).

2010-02-19  Donal K. Fellows  <[email protected]>

	* unix/installManPage: [Bug 2954638]: Correct behaviour of manual page
	installer. Also added armouring to check that assumptions about the
	initial state are actually valid (e.g., look for existing input file).

2010-02-17  Donal K. Fellows  <[email protected]>

	* generic/tclHash.c (HashStringKey):	Restore these hash functions
	* generic/tclLiteral.c (HashString):	to use the classic algorithm.
	* generic/tclObj.c (TclHashObjKey):	Community felt normal case
	speed to be more important than resistance to malicious cases. For
	now, hashes that need to deal with the malicious case can use a custom
	hash table and install their own hash function, though that is not
	functionality exposed to the script level.

	* generic/tclCompCmds.c (TclCompileDictUpdateCmd): Stack depth must be
	correctly described when compiling a body to prevent crashes in some
	debugging modes.

2010-02-16  Jan Nijtmans  <[email protected]>

	* generic/tclInt.h: Change order of various struct members,
	fixing potential binary incompatibility with Tcl 8.5

2010-02-16  Donal K. Fellows  <[email protected]>

	* unix/, 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.

	* generic/tclLiteral.c (HashString): Missed updating to FNV in one
	place; the literal table (a copy of the hash table code...)

2010-02-15  Jan Nijtmans  <[email protected]>

	* tools/genStubs.tcl:   Reverted earlier rename from tcl*Stubs to

2010-02-15  Donal K. Fellows  <[email protected]>

	* generic/tclOO.c (AllocObject, SquelchedNsFirst, ObjectRenamedTrace):
	* generic/tclNamesp.c (Tcl_DeleteNamespace): [Bug 2950259]: Revised
	the namespace deletion code to provide an additional internal callback
	that gets triggered early enough in namespace deletion to allow TclOO
	destructors to run sanely. Adjusted TclOO to take advantage of this,
	so making tearing down an object by killing its namespace appear to
	work seamlessly, which is needed for Itcl. (Note that this is not a
	feature that will ever be backported to 8.5, and it remains not a
	recommended way of deleting an object.)

2010-02-13  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c (TclCompileSwitchCmd): Divided the [switch]
	compiler into three pieces (after the model of [try]): a parser, an
	instruction-issuer for chained tests, and an instruction-issuer for
	jump tables.

	* generic/tclEnsemble.c: Split the ensemble engine out into its own
	file rather than keeping it mashed together with the namespace code.

2010-02-12  Jan Nijtmans  <[email protected]>

	* win/tcl.m4:		Use -pipe for gcc on win32
	* win/configure:	(mingw/cygwin) (regenerated)
	* win/.cvsignore:	Add .lib, .exp and .res here

2010-02-11  Mo DeJong  <[email protected]>

	* tests/list.test: Add tests for explicit \0 in a string argument to
	the list command.

2010-02-11  Donal K. Fellows  <[email protected]>

	* generic/tclIOCmd.c (Tcl_OpenObjCmd): [Bug 2949740]: Make sure that
	we do not try to put a NULL pipeline channel into binary mode.

2010-02-11  Mo DeJong  <[email protected]>

	[Bug 2826551, Patch 2948425]: Assorted regexp bugs related to -all,
	-line and -start options and newlines.
	* generic/tclCmdMZ.c (Tcl_RegexpObjCmd): If -offset is given, treat it
	as the start of the line if the previous character was a newline. Fix
	nasty edge case where a zero length match would not advance the index.
	* tests/regexp.test: Add regression tests back ported from Jacl.
	Checks for a number of issues related to -line and newline handling. A
	few of tests were broken before the patch and continue to be broken,
	marked as knownBug.

2010-02-11  Donal K. Fellows  <[email protected]>

	* generic/tclOO.c (ObjectRenamedTrace): [Bug 2949397]: Prevent
	destructors from running on the two core class objects when the whole
	interpreter is being destroyed.

2010-02-09  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c (TclCompileTryCmd, IssueTryInstructions)
	(IssueTryFinallyInstructions): Added compiler for the [try] command.
	It is split into three pieces that handle the parsing of the tokens,
	the issuing of instructions for finally-free [try], and the issuing of
	instructions for [try] with finally; there are enough differences
	between the all cases that it was easier to split the code rather than
	have a single function do the whole thing.

2010-02-09  Alexandre Ferrieux  <[email protected]>

	* tools/genStubs.tcl: Remove dependency on 8.5+ idiom "in" in

2010-02-08  Donal K. Fellows  <[email protected]>

	* generic/tclZlib.c (Tcl_ZlibDeflate, Tcl_ZlibInflate): [Bug 2947783]:
	Make sure that the result is an unshared object before appending to it
	so that nothing crashes if it is shared (use in Tcl code was not
	affected by this, but use from C was an issue).

2010-02-06  Donal K. Fellows  <[email protected]>

	* generic/tclHash.c (HashStringKey):	Replace Tcl's crusty old hash
	* generic/tclObj.c (TclHashObjKey):	function with the algorithm
	due to Fowler, Noll and Vo. This is slightly faster (assuming the
	presence of hardware multiply) and has somewhat better distribution
	properties of the resulting hash values. Note that we only ever used
	the 32-bit version of the FNV algorithm; Tcl's core hash engine
	assumes that hash values are simple unsigned ints.

	Code that depends on hash iteration order (especially tests) may well
	be disrupted by this. Where a definite order is required, the fix is
	usually to just sort the results after extracting them from the hash.
	Where this is insufficient, the code that has ceased working was
	always wrong and was only working by chance.

2010-02-05  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c (TclCompileErrorCmd): Added compilation of the
	[error] command. No new bytecodes.

2010-02-05  Jan Nijtmans  <nijtman[email protected]>

	* tools/genStubs.tcl:	Follow-up to earlier commit today:
	          Eliminate the need for an extra Stubs Pointer for adressing
	          a static stub table: Just change the exported table from
	          static to MODULE_SCOPE.
	* generic/tclBasic.c
	* generic/tclOO.c
	* generic/tclTomMathInterface.c
	* generic/tcl*Decls.h (regenerated)
	* generic/tclStubInit.c (regenerated)
	* generic/tclOOStubInit.c (regenerated)
	* generic/tclTest.c (minor formatting)

2010-02-05  Donal K. Fellows  <[email protected]>

	* generic/tclVar.c: More consistency in errorcode generation.

	* generic/tclOOBasic.c (TclOO_Object_Destroy): Rewrote to be NRE-aware
	when calling destructors. Note that there is no guarantee that
	destructors will always be called in an NRE context; that's a feature
	of the 'destroy' method only.

	* generic/tclEncoding.c: Add 'const' to many function-internal vars
	that are never pointing to things that are written to.

2010-02-05  Jan Nijtmans  <[email protected]>

	* tools/genStubs.tcl:	Follow-up to [2010-01-29] commit:
		prevent space within stub table function parameters if the
		parameter type is a pointer.
	* win/tclWinInt.h:	Minor Formatting
	* generic/tcl.h:	VOID -> void and other formatting
	* generic/tclInt.h:	Minor formatting
	* generic/tclInt.decls: Change signature of TclNRInterpProcCore,
	* generic/tclOO.decls:	and TclOONewProc(Instance|)MethodEx,
	* generic/tclProc.c:	indicating that errorProc is a function,
	* generic/tclOOMethod.c:pointer, and other formatting
	* generic/tcl*Decls.h:	(regenerated)
	* generic/tclVar.c:	gcc warning(line 3703): 'pattern' may be used
				uninitialized in this function
				gcc warning(line 3788): 'matched' may be used
				uninitialized in this function

2010-02-04  Donal K. Fellows  <[email protected]>

	* generic/tclVar.c: Added more use of error-codes and reduced the
	stack overhead of older interfaces.
	(ArrayGetCmd): Stop silly crash when using a trivial pattern due to
	error in conversion to ensemble.
	(ArrayNamesCmd): Use the object RE interface for faster matching.

2010-02-03  Donal K. Fellows  <[email protected]>

	* generic/tclVar.c (ArrayUnsetCmd): More corrections.

2010-02-02  Donal K. Fellows  <[email protected]>

	* generic/tclVar.c: Turned the [array] command into a true ensemble.

	* generic/tclOO.c (AllocObject, MyDeleted): A slightly faster way to
	handle the deletion of [my] is with a standard delete callback. This
	is because it doesn't require an additional memory allocation during
	object creation. Also reduced the amount of string manipulation
	performed during object creation to further streamline memory
	handling; this is not backported to the 8.5 package as it breaks a
	number of abstractions.

	* generic/tclOOBasic.c (TclOO_Object_Destroy): [Bug 2944404]: Do not
	crash when a destructor deletes the object that is executing that

2010-02-01  Donal K. Fellows  <[email protected]>

	* generic/tclVar.c (Tcl_ArrayObjCmd): [Bug 2939073]: Stop the [array
	unset] command from having dangling pointer problems when an unset
	trace deletes the element that is going to be processed next. Many
	thanks to Alexandre Ferrieux for the bulk of this fix.

	* generic/regexec.c (ccondissect, crevdissect): [Bug 2942697]: Rework
	these functions so that certain pathological patterns are matched much
	more rapidly. Many thanks to Tom Lane for dianosing this issue and
	providing an initial patch.

2010-01-30  Donal K. Fellows  <[email protected]>

	* generic/tclCompile.c (tclInstructionTable):	Bytecode instructions
	* generic/tclCompCmds.c (TclCompileUnsetCmd):	to allow the [unset]
	* generic/tclExecute.c (TclExecuteByteCode):	command to be compiled
	with the compiler being a complete compilation for all compile-time
	decidable uses.

	* generic/tclVar.c (TclPtrUnsetVar): Var reference version of the code
	to unset a variable. Required for INST_UNSET bytecodes.

2010-01-29  Jan Nijtmans  <[email protected]>

	* generic/tcl.h: [Bug 2942081]: Reverted Tcl_ThreadDataKey type change
				Changed some Tcl_CallFrame fields from "char *"
				to "void *". This saves unnecessary space on
				Cray's (and it's simply more correct).

	* tools/genStubs.tcl:	No longer generate a space after "*" and
				immediately after a function name, so the
				format of function definitions in tcl*Decls.h
				match all other tcl*.h header files.
	* doc/ParseArgs.3:	Change Tcl_ArgvFuncProc, Tcl_ArgvGenFuncProc
	* generic/tcl.h:	and GetFrameInfoValueProc to be function
	* generic/tclInt.h:	definitions, not pointers, for consistency
	* generic/tclOOInt.h:	with all other Tcl function definitions.

2010-01-28  Donal K. Fellows  <[email protected]>

	* generic/tclOOBasic.c (TclOO_Object_Destroy): Move the execution of
	destructors to a point where they can produce an error. This will not
	work for all destructors, but it does mean that more failing calls of
	them will be caught.
	* generic/tclOO.c (AllocObject, MyDeletedTrace, ObjectRenamedTrace):
	(ObjectNamespaceDeleted): Stop various ways of getting at commands
	with dangling pointers to the object. Also increases the reliability
	of calling of destructors (though most destructors won't benefit; when
	an object is deleted namespace-first, its destructors are not run in a
	nice state as the namespace is partially gone).

	* 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

	automatic regeneration of this part is not possible because it wrongly
	puts 'safe::Setup' on the list, and wrongly leaves out 'safe::Log'
	which is more dynamically created than the generator expects.

	Further note that the file "clock.tcl" is explicitly loaded by
	"init.tcl", the first time the clock command is invoked. The relevant
	code can be found at line 172ff, roughly, the definition of the
	procedure 'clock'. This means none of the procedures of this file
	belong in the tclIndex. Another indicator that automatic regeneration
	of tclIndex is ill-advised.

2009-11-06  Andreas Kupries  <[email protected]>

	* library/safe.tcl (::safe::Setup): Added documentation of the
	contents of the state array. Also killed the 'InterpState' procedure
	with its upleveled variable/upvar combination, and replaced all uses
	with 'namespace upvar'.

2009-11-05  Andreas Kupries  <[email protected]>

	* library/safe.tcl: A series of patches which bring the SafeBase up to
	date with code guidelines, Tcl's features, also eliminating a number
	of inefficiencies along the way.
	(1) Changed all procedure names to be fully qualified.
	(2) Moved the procedures out of the namespace eval. Kept their
	locations. IOW, broke the namespace eval apart into small sections not
	covering the procedure definitions.
	(3) Reindented the code. Just lots of whitespace changes.
	Functionality unchanged.
	(4) Moved the multiple namespace eval's around. Command export at the
	top, everything else (var decls, argument parsing setup) at the
	(5) Moved the argument parsing setup into a procedure called when the
	code is loaded. Easier management of temporary data.
	(6) Replaced several uses of 'Set' with calls to the new procedure
	'InterpState' and direct access to the per-slave state array.
	(7) Replaced the remaining uses of 'Set' and others outside of the
	path/token handling, and deleted a number of procedures related to
	state array access which are not used any longer.
	(8) Converted the path token system to cache normalized paths and path
	<-> token conversions. Removed more procedures not used any longer.
	Removed the test cases 4.3 and 4.4 from safe.test. They were testing
	the now deleted command "InterpStateName".
	(9) Changed the log command setup so that logging is compiled out
	completely when disabled (default).
	(10) Misc. cleanup. Inlined IsInterp into CheckInterp, its only user.
	Consistent 'return -code error' for error reporting. Updated to use
	modern features (lassign, in/ni, dicts). The latter are used to keep a
	reverse path -> token map and quicker check of existence.
	(11) Fixed [Bug 2854929]: Recurse into all subdirs under all TM root
	dirs and put them on the access path.

	what the fundamental semantics of an object actually are.

2009-11-01  Joe Mistachkin  <[email protected]>

	* doc/Cancel.3: Minor cosmetic fixes.
	* win/ Make htmlhelp target work again.  An extra set of
	double quotes around the definition of the HTML help compiler tool
	appears to be required.  Previously, there was one set of double
	quotes around the definition of the tool and one around the actual
	invocation.  This led to confusion because it was the only such tool
	path to include double quotes around its invocation.  Also, it was
	somewhat inflexible in the event that somebody needed to override the
	tool command to include arguments.  Therefore, even though it may look
	"wrong", there are now two double quotes on either side of the tool
	path definition.  This fixes the problem that currently prevents the
	htmlhelp target from building and maintains flexibility in case
	somebody needs to override it via the command line or an environment

	* tests/tcltest.test: When creating the notwritabledir we deny the
	current user access to delete the file. We must grant this right when
	we cleanup. Required on Windows 7 when the user does not automatically
	have administrator rights.

2009-10-29  Don Porter  <[email protected]>

	* generic/tcl.h:        Changed the typedef for the mp_digit type
		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.  [Bug

	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.

2009-10-28  Don Porter  <[email protected]>

	* generic/tclLiteral.c:	[Bug 2888044]: Fixed 2 bugs.
	* tests/info.test:	First, as noted in the comments of the
	TclCleanupLiteralTable routine, since the teardown of the intrep of
	one Tcl_Obj can cause the teardown of others in the same table, the
	full table cleanup must be done with care, but the code did not
	contain the same care demanded in the comment.  Second, recent
	additions to the info.test file had poor hygiene, leaving an array
	variable ::a lying around, which breaks later interp.test tests during
	a -singleproc 1 run of the test suite.

2009-10-28  Kevin B. Kenny  <[email protected]>

	* generic/tclIO.c:      [Patch 2107634]: Revised ReadChars and

	Reported by emiliano on the chat.

2009-10-06  Don Porter  <[email protected]>

	* generic/tclInterp.c (SlaveEval): Agressive stomping of internal reps
	was added as part of the NRE patch of 2008-07-13.  This doesn't appear
	to actually be needed, and it hurts quite a bit when large lists lose
	their intreps and require reparsing.  Thanks to Ashok Nadkarni for
	reporting the problem.

	* generic/tclCmdAH.c (TclNRForObjCmd, TclNRForIterCallback,
	* generic/tclCmdMZ.c (TclNRWhileObjCmd):

	Extended the bytecode compiler initialization to recognize the
	compilation of whole files (NRE enabled 'source' command) and switch
	to the counting of absolute lines in that case.

	Further extended the bytecode compiler to track the start line in the
	generated information, and modified the bytecode execution to
	recompile an object if the location as per the calling context doesn't
	match the location saved in the bytecode. This part could be optimized
	more by using more memory to keep all possibilities which occur
	around, or by just adjusting the location information instead of a
	total recompile.

	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,
	and the previous change remove the problems with location data caused
	by literal sharing (across whole files, but also proc bodies).
	Simplified the associated datastructures (ExtIndex is gone, as is the
	function EnterCmdWordIndex).

	The last change causes the hashtable 'lineLABCPtr' to be state which
	has to be kept per coroutine, like the CmdFrame stack. Reworked the
	coroutine support code to create, delete and switch the information as
	needed. Further reworked the tailcall command as well, it has to pop
	its own arguments when run in a bytecode context to keep a proper
	stack in 'lineLABCPtr'.

	Fixed the mishandling of line information in the NRE-enabled 'for' and
	'while' commands introduced when both were made to share their
	iteration callbacks without taking into account that the loop body is
	found in different words of the command. Introduced a separate data
	structure to hold all the callback information, as we went over the
	limit of 4 direct client-data values for NRE callbacks.

	The above fixes [Bug 1605269].

2009-02-21  Don Porter  <[email protected]>

	* generic/tclStringObj.c:	Several revisions to the shimmering
	patterns between Unicode and UTF string reps.  Most notably the
	call: objPtr = Tcl_NewUnicodeObj(...,0); followed by a loop of calls:
	Tcl_AppendUnicodeToObj(objPtr, u, n); will now grow and append to
	the Unicode representation.  Before this commit, the sequence would
	convert each append to UTF and perform the append to the UTF rep.
	This is puzzling and likely a bug.  The performance of [string map]
	is significantly improved by this change (according to the MAP
	collection of benchmarks in tclbench).  Just in case there was some
	wisdom in the old ways that I missed, I left in the ability to restore
	the old patterns with a #define COMPAT 1 at the top of the file.

	where "volumerelative" is another possibility.

	* generic/tclStringObj.c:	Simplify the logic of the
	Tcl_*SetObjLength() routines.

	* generic/tclStringObj.c:	Rewrite GrowStringBuffer() so that it
	has parallel structure with GrowUnicodeBuffer().  The revision permits
	allocation attempts to continue all the way up to failure, with no
	gap. It also directly manipulates the String and Tcl_Obj internals
	instead of inefficiently operating via Tcl_*SetObjLength() with all of
	its extra protections and underdocumented special cases.

	* generic/tclStringObj.c:	Another round of simplification on
	the allocation macros.

2009-02-17  Jeff Hobbs  <[email protected]>

	* win/tcl.m4, win/configure: Check if cl groks _WIN64 already to
	avoid CC manipulation that can screw up later configure checks.
	Use 'd'ebug runtime in 64-bit builds.

2009-02-17  Don Porter  <[email protected]>

	* generic/tclStringObj.c:	Pare back the length of the unicode
	array in a non-extended String struct to one Tcl_UniChar, meant to
	hold the terminating NUL character.  Non-empty unicode strings are
	then stored by extending the String struct by stringPtr->maxChars
	additional slots in that array with sizeof(Tcl_UniChar) bytes per
	slot. This revision makes the allocation macros much simpler.

	* generic/tclStringObj.c:	Factor out common GrowUnicodeBuffer()
	and solve overflow and growth algorithm fallbacks in it.

	* generic/tclStringObj.c:	Factor out common GrowStringBuffer().

	* generic/tclStringObj.c:	Convert Tcl_AppendStringsToObj into
	* tests/stringObj.test:		a radically simpler implementation
	where we just loop over calls to Tcl_AppendToObj.  This fixes [Bug
	2597185].  It also creates a *** POTENTIAL INCOMPATIBILITY *** in
	that T_ASTO can now allocate more space than is strictly required,
	like all the other Tcl_Append* routines.  The incompatibility was
	detected by test stringObj-6.5, which I've updated to reflect the
	new behavior.

	* generic/tclStringObj.c:	Revise buffer growth implementation
	in ExtendStringRepWithUnicode.  Use cheap checks to determine that
	no reallocation is necessary without cost of computing the precise
	number of bytes needed.  Also make use of the string growth algortihm
	in the case of repeated appends.

	* generic/tclStringObj.c:	Replace the 'size_t uallocated' field
	of the String struct, storing the number of bytes allocated to store
	the Tcl_UniChar array, with an 'int maxChars' field, storing the
	number of Tcl_UniChars that may be stored in the allocated space.
	This reduces memory requirement a small bit, and makes some range
	checks simpler to code.
	* generic/tclTestObj.c:	Replace the [teststringobj ualloc] testing
	* tests/stringObj.test:	command with [teststringobj maxchars] and
	update the tests.

	* generic/tclStringObj.c:	Removed limitation in
	Tcl_AppendObjToObj where the char length of the result was only
	computed if the appended string was all single byte characters.
	This limitation was in place to dodge a bug in Tcl_GetUniChar.
	With that bug gone, we can take advantage of always recording the
	length of append results when we know it.

2009-02-14  Don Porter  <[email protected]>

	* generic/tclStringObj.c:	Revisions so that we avoid creating
	the strange representation of an empty string with
	objPtr->bytes == NULL and stringPtr->hasUnicode == 0.  Instead in
	the situations where that was being created, create a traditional
	two-legged stork representation (objPtr->bytes = tclEmptyStringRep
	and stringPtr->hasUnicode = 1).  In the situations where the strange
	rep was treated differently, continue to do so by testing
	stringPtr->numChars == 0 to detect it.  These changes make the code
	more conventional so easier for new maintainers to pick up.  Also
	sets up further simplifications.

	* generic/tclTestObj.c:	Revise updates to [teststringobj] so we don't
	get blocked by MODULE_SCOPE limits.

2009-02-12  Don Porter  <[email protected]>

	* generic/tclStringObj.c:	Rewrites of the routines
	Tcl_GetCharLength, Tcl_GetUniChar, Tcl_GetUnicodeFromObj,
	Tcl_GetRange, and TclStringObjReverse to use the new macro, and
	to more simply and clearly split the cases depending on whether
	a valid unicode rep is present or needs to be created.
	New utility routine UnicodeLength(), to compute the length of unicode
	buffer arguments when no length is passed in, with built-in
	overflow protection included.  Update three callers to use it.

	* generic/tclInt.h:	New macro TclNumUtfChars meant to be a faster
	replacement for a full Tcl_NumUtfChars() call when the string has all
	single-byte characters.

	* generic/tclStringObj.c:	Simplified Tcl_GetCharLength by
	* generic/tclTestObj.c:		removing code that did nothing.
	Added early returns from Tcl_*SetObjLength when the desired length
	is already present; adapted test command to the change.

	* generic/tclStringObj.c:	Re-implemented AppendUtfToUnicodeRep
	so that we no longer pass through Tcl_DStrings which have their own
	sets of problems when lengths overflow the int range.  Now AUTUR and
	FillUnicodeRep share a common core routine.

	Simplify SetStringFromAny() by removing unreachable and duplicate code.
	Simplify Tcl_SetObjLength by removing unreachable code.
	Removed handling of (objPtr->bytes != NULL) from UpdateStringOfString,
	which is only called when objPtr->bytes is NULL.

2009-02-05  Donal K. Fellows  <[email protected]>

	* generic/tclCmdMZ.c (StringIndexCmd, StringRangeCmd, StringLenCmd):
	Simplify the implementation of some commands now that the underlying
	string API knows more about bytearrays.

	* generic/tclExecute.c (TclExecuteByteCode): [Bug 2568434]: Make sure
	that INST_CONCAT1 will not lose string reps wrongly.

	* generic/tclStringObj.c (Tcl_AppendObjToObj): Special-case the
	appending of one bytearray to another, which can be extremely rapid.
	Part of scheme to address [Bug 1665628] by making the basic string
	operations more efficient on byte arrays.
	(Tcl_GetCharLength, Tcl_GetUniChar, Tcl_GetRange): More special casing
	work for bytearrays.

2009-02-04  Don Porter  <[email protected]>

	* generic/tclStringObj.c: [Bug 2561794]: Added overflow protections to

2009-02-02  Don Porter  <[email protected]>

	* generic/tclInterp.c:	Reverted the conversion of [interp] into an
	* tests/interp.test:	ensemble.  Such conversion is not necessary
	* tests/nre.test:	(or even all that helpful) in the NRE-enabling

	* generic/tclStringObj.c (Tcl_(Attempt)SetObjLength):	[Bug 2553906]:

	* unix/ [Patch 907924]:Added a CONFIG_INSTALL_DIR
	* unix/tcl.m4:      parameter so that distributors can control where goes. Made the installation of 'ldAix' conditional upon
	actually being on an AIX system. Allowed for downstream packagers to
	customize SHLIB_VERSION on BSD-derived systems. Thanks to Stuart
	Cassoff for his help.
	* unix/configure: Autoconf 2.59

2009-01-19  David Gravereaux  <[email protected]>

	* win/ Improved tools detection and error message
	* win/ Reorganized the $(TCLOBJ) file list into seperate
	parts for easier maintenance. Matched all sources built using -GL to
	both $(lib) and $(link) to use -LTCG and avoid a warning message.
	Addressed the over-building nature of the htmlhelp target by moving
	from a pseudo target to a real target dependent on the entire docs/
	directory contents.
	* win/nmakehlp.c: Removed -g option and GrepForDefine() func as it
	isn't being used anymore. The -V option method is much better.

2009-01-16  Don Porter  <[email protected]>

	* generic/tcl.h:	Bump patchlevel to 8.6b1.1 to distinguish
	* library/init.tcl:	CVS snapshots from the 8.6b1 and 8.6b2 releases
	* unix/	and to deal with the fact that the 8.6b1
	* win/	version of init.tcl will not [source] in the
	HEAD version of Tcl.

	* unix/configure:	autoconf-2.59
	* win/configure:

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken):	Reverted most
	of the substance of my 2009-01-12 commit. NULLing the objProc field of
	a Command when deleting it is important so that tests for certain
	classes of commands don't return false positives when applied to
	deleted command tokens. Overall change is now just replacement of a
	false comment with a true one.

2009-01-13  Jan Nijtmans  <[email protected]>

	* unix/tcl.m4: [Bug 2502365]: Building of head on HPUX is broken when

	* generic/tclCmdMZ.c (Tcl_ThrowObjCmd):	Move implementation of [throw]
	* library/init.tcl (throw):		to C from Tcl.

2009-01-12  Don Porter  <[email protected]>

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken): One consequence of
	the NRE rewrite is that there are now situations where a NULL objProc
	field in a Command struct is perfectly normal. Removed an outdated
	comment in Tcl_DeleteCommandFromToken that claimed we use
	cmdPtr->objPtr==NULL as a test of command validity. In fact we use
	cmdPtr->flags&CMD_IS_DELETED to perform that test. Also removed the
	setting to NULL, since any extension following the advice of the old
	comment is going to be broken by NRE anyway, and needs to shift to
	flag-based testing (or stop intruding into such internal matters).
	Part of [Bug 2486550].

2009-01-09  Don Porter  <[email protected]>

	* generic/tclStringObj.c (STRING_SIZE): [Bug 2494093]: Corrected
	failure to limit memory allocation requests to the sizes that can be

2009-01-08  Don Porter  <[email protected]>

	* generic/tclStringObj.c (STRING_UALLOC): [Bug 2494093]: Added missing
	parens required to get correct results out of things like
	STRING_UALLOC(num + append).

	* generic/tclDictObj.c, generic/tclIndexObj.c, generic/tclListObj.c,
	* generic/tclObj.c, generic/tclStrToD.c, generic/tclUtil.c,
	* generic/tclVar.c: Generate errorcodes for the error cases which
	approximate to "I can't interpret that string as one of those" and
	"You gave me the wrong number of arguments".

2009-01-07  Donal K. Fellows  <[email protected]>

	* doc/dict.n: [Tk Bug 2491235]: Added more examples.

	* tests/oo.test (oo-22.1): Adjusted test to be less dependent on the
	specifics of how [info frame] reports general frame information, and
	instead to focus on what methods add to it; that's really what the
	test is about anyway.

2009-01-06  Don Porter  <[email protected]>

	* tests/stringObj.test:	Revise tests that demand a NULL Tcl_ObjType
	in certain values to construct those values with [testdstring] so
	there's no lack of robustness depending on the shimmer history of
	shared literals.

2009-01-06  Donal K. Fellows  <[email protected]>

	* generic/tclDictObj.c (DictIncrCmd): Corrected twiddling in internals
	of dictionaries so that literals can't get destroyed.

	* tests/expr.test: [Bug 2006879]: Eliminate non-ASCII char.

	* generic/tclOOInfo.c (InfoObjectMethodsCmd,InfoClassMethodsCmd):
	[Bug 2489836]: Only delete pointers that were actually allocated!

	* generic/tclOO.c (TclNRNewObjectInstance, Tcl_NewObjectInstance):
	[Bug 2481109]: Perform search for existing commands in right context.

2009-01-05  Donal K. Fellows  <[email protected]>

	* generic/tclCmdMZ.c (TclNRSourceObjCmd): [Bug 2412068]: Make
	* generic/tclIOUtil.c (TclNREvalFile):    implementation of the

	sourced in a coroutine can work.

2009-01-04  Donal K. Fellows  <[email protected]>

	* generic/tclCmdAH.c: Tidy up spacing and code style.

2009-01-03  Kevin B. Kenny  <kenn[email protected]>

	* library/clock.tcl (tcl::clock::add): Fixed error message formatting
	in the case where [clock add] is presented with a bad switch.
	* tests/clock.test (clock-65.1) Added a test case for the above
	problem [Bug 2481670].

2009-01-02  Donal K. Fellows  <[email protected]>

	* unix/tcl.m4 (SC_CONFIG_CFLAGS): [Bug 878333]: Force the use of the
	compatibility version of mkstemp() on IRIX.
	* unix/, unix/ (mkstemp.o):
	* compat/mkstemp.c (new file): [Bug 741967]: Added a compatibility
	implementation of the mkstemp() function, which is apparently needed
	on some platforms.
