Artifact 495833d6b8cc19a1e68a59868d963c9e5ffa0ea9298bb10a3a77e57c07b1e8a9:

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.

	* doc/next.n (METHOD SEARCH ORDER): Bug [3606943]: Corrected
	description of method search order.

2013-09-18  Donal Fellows  <>

	Bump TclOO version to 1.0.1 for release.

2013-09-17  Donal Fellows  <>

	* 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  <>

	* generic/tclOOMethod.c (CloneProcedureMethod): [Bug 3609693]: Strip
	the internal representation of method bodies during cloning in order
	to ensure that any bound references to instance variables are removed.

2013-09-01  Donal Fellows  <>

	* generic/tclBinary.c (BinaryDecodeHex): [Bug b98fa55285]: Ensure that
	whitespace at the end of a string don't cause the decoder to drop the
	last decoded byte.

2013-08-03  Donal Fellows  <>

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

2013-06-09  Donal K. Fellows  <>

	* 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  <>

	* 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.

2013-06-04  Jan Nijtmans  <>

	* 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  <>

	* 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  <>

	* 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  <>

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

	[lsearch -nocase] and [lsort -nocase].

2013-05-22  Donal K. Fellows  <>

	* doc/file.n: [Bug 3613671]: Added note to portability section on the

	for checking return code of access() system call, which was inverted.

2013-05-19  Jan Nijtmans  <>

	* unix/tcl.m4:     Fix for FreeBSD, and remove support for older

2013-05-10  Donal K. Fellows  <>

	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  <>

	* 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  <>

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

	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  <>

	* 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  <>

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

	* generic/regerrs.h:	"colors" in a regular expression overflows a

	* 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

	* 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.

	* 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

	* 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
	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.

	* 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.)

	* 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.

	'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".

	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  <>

	* 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.

	in the case of repeated appends.
