	* doc/Hash.3:
	* generic/tclHash.c:
	* generic/tclObj.c:  
	* generic/tclThreadStorage.c: (changes part of the patch below) 
	Stop Tcl_CreateHashVar from resetting hPtr->clientData to NULL
	after calling the allocEntryProc for a custom table. 
	
	* generic/tcl.h:
	* generic/tclBasic.c:
	* generic/tclCmdIL.c:
	* generic/tclCompCmds.c:
	* generic/tclCompile.c:
	* generic/tclCompile.h:
	* generic/tclExecute.c:
	* generic/tclHash.c:
	* generic/tclInt.decls:
	* generic/tclInt.h:
	* generic/tclIntDecls.h:
	* generic/tclLiteral.c:
	* generic/tclNamesp.c:
	* generic/tclObj.c:
	* generic/tclProc.c:
	* generic/tclThreadStorage.c:
	* generic/tclTrace.c:
	* generic/tclVar.c:   VarReform [Patch 1750051]

	*** 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 malfunction.
	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 struct.

2007-07-31  Miguel Sofer  <msofer@users.sf.net>

	* unix/configure.in: allow use of 'inline' in Tcl sources
	* win/configure.in:  [Patch 1754128]
	* win/makefile.vc:   Regen with autoconf 2.61
	
2007-07-31  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* unix/tclUnixInit.c (TclpSetVariables): Use the thread-safe getpwuid
	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
	file clearer.

2007-07-24  Miguel Sofer  <msofer@users.sf.net>

	* 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
	* unix/Makefile.in: the special linux and solaris forms would not
	* 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
	simpler. [FRQ 951168]

2007-07-02  Don Porter  <dgp@users.sourceforge.net>

	* 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
	alternative.

	* generic/tclIO.c:	Removed dead code.
	* unix/tclUnixChan.c:

	* generic/tclCompExpr.c:	Removed dead code, old implementations
	* generic/tclEvent.c:	of expr parsing and compiling, including the
	* generic/tclInt.h:	routine TclFinalizeCompilation().

2007-06-30  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Plug a memory leak caused by a
	missing Tcl_DecrRefCount on an error path. [Bug 1717186]

2007-06-30  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

	* generic/tclThread.c: Prevent RemeberSyncObj() from growing the sync
	object lists by reusing already free'd slots, if possible. See
	discussion on Bug 1726873 for more information.

2007-06-29  Donal K. Fellows  <dkf@users.sf.net>

	* doc/DictObj.3 (Tcl_DictObjDone): Improved documentation of this
	function to make it clearer how to use it. [Bug 1710795]

2007-06-29  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclAlloc.c:		on Darwin, ensure memory allocated by
	* generic/tclThreadAlloc.c:	the custom TclpAlloc()s is aligned to
	16 byte boundaries (as is the case with the Darwin system malloc).

	* generic/tclGetDate.y:	use ckalloc/ckfree instead of malloc/free.
	* generic/tclDate.c:	bison 1.875e

	* generic/tclBasic.c (TclEvalEx): fix warnings.

	* macosx/Tcl.xcodeproj/project.pbxproj:	improve support for renamed tcl
	* macosx/Tcl.xcodeproj/default.pbxuser:	source dir; add 10.5 SDK build
	* macosx/Tcl-Common.xcconfig:		config; remove tclMathOp.c.

	* macosx/README: document Tcl.xcodeproj changes.

2007-06-28  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:		Removed dead code, including the
	* generic/tclExecute.c:		entire file tclMathOp.c.
	* generic/tclInt.h:
	* generic/tclMathOp.c (removed):
	* generic/tclTestObj.c:
	* win/tclWinFile.c:

	* unix/Makefile.in:	Updated to reflect deletion of tclMathOp.c.
	* win/Makefile.in:
	* win/makefile.bc:
	* win/makefile.vc:

2007-06-28  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* generic/tclBasic.c:     Silence constness warnings for TclStackFree
	* generic/tclCompCmds.c:  when building with msvc.
	* generic/tclFCmd.c:
	* generic/tclIOCmd.c:
	* generic/tclTrace.c:

2007-06-28  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (UnsetVarStruct): fix possible segfault.

2007-06-27  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclTrace.c:   Corrected broken trace reversal logic in
	* generic/tclTest.c:    TclCheckInterpTraces that led to infinite loop
	* tests/trace.test:     when multiple Tcl_CreateTrace traces were set
	and one of them did not fire due to level restrictions.  [Bug 1743931].

2007-06-26  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c (TclEvalEx):	Moved some arrays from the C
	stack to the Tcl stack.

2007-06-26  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (UnsetVarStruct): more streamlining.

2007-06-25  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c:	Safety checks to avoid crashes in the
	TclStack* routines when called with an incompletely initialized
	interp. [Bug 1743302]

2007-06-25  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (UnsetVarStruct): fixing incomplete change, more
	streamlining.

2007-06-24  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (TclDeleteCompiledLocalVars): removed inlining that
	ended up not really optimising (limited benchmarks). Now calling
	UnsetVarStruct (streamlined old code is #ifdef'ed out, in case better
	benchmarks do show a difference).

	* generic/tclVar.c (UnsetVarStruct): fixed a leak introduced in last
	commit.

2007-06-23  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (UnsetVarStruct, TclDeleteVars): made the logic
	slightly clearer, eliminated some duplicated code.

	*** POTENTIAL INCOMPATIBILITY *** (tclInt.h and Var struct users)
	The core never builds VAR_LINK variable to have traces. Such a
	"monster", should one exist, will now have its unset traces called
	*before* it is unlinked.

2007-06-23  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/tclMacOSXNotify.c (AtForkChild): don't call CoreFoundation
	APIs after fork() on systems where that would lead to an abort().

2007-06-22  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c:	Revised TclStackRealloc() signature to better
	* generic/tclInt.h:	parallel (and fall back on) Tcl_Realloc.

	* generic/tclNamesp.c (TclResetShadowesCmdRefs):	Replaced
	ckrealloc based allocations with TclStackRealloc allocations.

	* generic/tclCmdIL.c:	More conversions to use TclStackAlloc.
	* generic/tclScan.c:

2007-06-21  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:	 Move most instances of the Tcl_Parse struct
	* generic/tclCompExpr.c: off the C stack and onto the Tcl stack. This
	* generic/tclCompile.c:	 is a rather large struct (> 3kB).
	* generic/tclParse.c:

2007-06-21  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c (TEOvI):          Made sure that leave traces
	* generic/tclExecute.c (INST_INVOKE):  that were created during
	* tests/trace.test (trace-36.2):       execution of an originally
	untraced command do not fire [Bug 1740962], partial fix.

2007-06-21  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tcl.h, generic/tclCompile.h, generic/tclCompile.c: Remove
	references in comments to obsolete {expand} notation. [Bug 1740859]

2007-06-20  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c: streamline namespace vars deletion: only compute
	the variable's full name if the variable is traced.

2007-06-20  Don Porter  <dgp@users.sourceforge.net>

	* 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
	(interp == NULL), in which case they simply fall back to be calls to
	Tcl_Alloc/Tcl_Free.

	* generic/tclIntDecls.h:	make genstubs

	* generic/tclBasic.c:	Updated callers
	* generic/tclCmdAH.c:
	* generic/tclCmdIL.c:
	* generic/tclCompCmds.c:
	* generic/tclCompExpr.c:
	* generic/tclCompile.c:
	* generic/tclFCmd.c:
	* generic/tclFileName.c:
	* generic/tclIOCmd.c:
	* generic/tclIndexObj.c:
	* generic/tclInterp.c:
	* generic/tclNamesp.c:
	* generic/tclProc.c:
	* generic/tclTrace.c:
	* unix/tclUnixPipe.c:

2007-06-20  Jeff Hobbs  <jeffh@ActiveState.com>

	* tools/tcltk-man2html.tcl: revamp of html doc output to use CSS,
	standardized headers, subheaders, dictionary sorting of names.

2007-06-18  Jeff Hobbs  <jeffh@ActiveState.com>

	* tools/tcltk-man2html.tcl: clean up copyright merging and output.
	clean up coding constructs.

2007-06-18  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCmdIL.c (InfoFrameCmd):
	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd):
	* generic/tclCompile.c (TclInitCompileEnv):
	* generic/tclProc.c (Tcl_ProcObjCmd, SetLambdaFromAny): Moved the
	CmdFrame off the C stack and onto the Tcl stack.

	* generic/tclExecute.c (TEBC):	Moved the CmdFrame off the C stack and
	onto the Tcl stack, between the catch and the execution stacks

2007-06-18  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c (TclEvalEx,TclEvalObjEx):	Moved the CmdFrame off
	the C stack and onto the Tcl stack.

2007-06-17  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclProc.c (TclObjInterpProcCore): Minor fixes to make
	* generic/tclExecute.c (TclExecuteByteCode): compilation debugging
	builds work again. [Bug 1738542]

2007-06-16  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclProc.c (TclObjInterpProcCore): Use switch instead of a
	chain of if's for a modest performance gain and a little more clarity.

2007-06-15  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompCmds.c:  Simplified [variable] compiler and executor.
	* generic/tclExecute.c:   Missed updates to "there is always a valid
	frame".

	* 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
	below.

	* 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/tclInt.h:       to reduce stack consumption and improve task
	* generic/tclIntDecls.h:  separation. Changes the interface of
	* generic/tclProc.c:      TclObjInterpProcCore (patching TclOO
	simultaneously).

	* 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
	management.

	* 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.
	***THIS CHANGE IS UNDER REVIEW***

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]

	***POTENTIAL INCOMPATIBILITY in internal API***
	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/tclInterp.c:

	* generic/tclInt.h:     New TclCleanupCommandMacro for core usage.
	* generic/tclBasic.c:
	* generic/tclExecute.c:
	* generic/tclObj.c:

2007-06-09 Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.xcodeproj/project.pbxproj: add new Tclsh-Info.plist.in.

2007-06-08  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdMZ.c (Tcl_StringObjCmd): Changed [string first] and
	* doc/string.n: [string last] so that they have clearer descriptions
	for those people who know the adage about needles and haystacks. This
	follows suggestions on comp.lang.tcl...

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

	* generic/tclParse.c: fix for uninit read [Bug 1732414].

2007-06-06  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.xcodeproj/project.pbxproj: add settings for Fix&Continue.

	* unix/configure.in (Darwin):		add plist for tclsh; link the
	* unix/Makefile.in  (Darwin):		Tcl and tclsh plists into their
	* macosx/Tclsh-Info.plist.in (new):	binaries in all cases.
	* macosx/Tcl-Common.xcconfig:

	* unix/tcl.m4 (Darwin): fix CF checks in fat 32&64bit builds.
	* unix/configure: autoconf-2.59

2007-06-05  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Added interp flag value ERR_LEGACY_COPY to
	* generic/tclInt.h:	control the timing with which the global
	* generic/tclNamesp.c:	variables ::errorCode and ::errorInfo get
	* generic/tclProc.c:	updated after an error.  This keeps more
	* generic/tclResult.c:	precise compatibility with Tcl 8.4.
	* tests/result.test (result-6.2):	[Bug 1649062]

2007-06-05  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInt.h:
	* generic/tclExecute.c: Tcl-stack reform, [Patch 1701202]

2007-06-03  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in: add datarootdir to silence autoconf-2.6x warning.

2007-05-30  Don Porter  <dgp@users.sourceforge.net>

	* 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]

2007-05-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclUnixThrd.c (Tcl_JoinThread): fix for 64-bit handling of
	pthread_join exit return code storage. [Bug 1712723]

2007-05-18  Don Porter  <dgp@users.sourceforge.net>

	* unix/configure:	autoconf-2.59 (FC6 fork)
	* win/configure:

	* README:		Bump version number to 8.5a7
	* generic/tcl.h:
	* library/init.tcl:
	* tools/tcl.wse.in:
	* unix/configure.in:
	* unix/tcl.spec:
	* win/configure.in:

	* generic/tclParse.c:	Disable and remove the ALLOW_EXPAND sections
	* tests/info.test:	that continued to support the deprecated
	* tests/mathop.test:	{expand} syntax.  Updated the few remaining
	users of that syntax in the test suite.

2007-05-17  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclExecute.c (TclLimitReady): Created a macro version of
	Tcl_LimitReady just for TEBC, to reduce the amount of times that the
	bytecode engine calls out to external functions on the critical path.
	* generic/tclInterp.c (Tcl_LimitReady): Added note to remind anyone
	doing maintenance that there is a macro version to update.

2007-05-17  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tcl.decls: workaround 'make checkstubs' failures from
	tclStubLib.c MODULE_SCOPE revert. [Bug 1716117]

2007-05-16  Joe English  <jenglish@users.sourceforge.net>

	* generic/tclStubLib.c:  Change Tcl_InitStubs(), tclStubsPtr, and the
	auxilliary stubs table pointers back to public visibility.

	These symbols need to be exported so that stub-enabled extensions may
	be statically linked into an extended tclsh or Big Wish with a
	dynamically-linked libtcl. [Bug 1716117]

2007-05-15  Don Porter  <dgp@users.sourceforge.net>

	* win/configure:	autoconf-2.59 (FC6 fork)

	* library/reg/pkgIndex.tcl:	Bump to registry 1.2.1 to account for
	* win/configure.in:		[Bug 1682211] fix.
	* win/makefile.bc:
	* win/tclWinReg.c:

2007-05-11  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* generic/tclInt.h: Removed TclEvalObjEx and TclGetSrcInfoForPc from
	tclInt.h now they are in the internal stubs table.

2007-05-09  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclInt.h:	TclFinalizeThreadAlloc() is always defined, so
	make sure it is also always declared (with MODULE_SCOPE).

2007-05-09  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclInt.h: fix warning when building threaded with -DPURIFY.

	* macosx/Tcl.xcodeproj/project.pbxproj: add 'DebugUnthreaded' &
	* macosx/Tcl.xcodeproj/default.pbxuser: 'DebugLeaks' targets and env
	var settings needed to run the 'leaks' tool.

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

	[Tcl Bug 1706140]

	* generic/tclLink.c (LinkTraceProc):	Update Tcl_VarTraceProcs so
	* generic/tclNamesp.c (Error*Read):	they call Tcl_InterpDeleted()
	* generic/tclTrace.c (Trace*Proc):	for themselves, and do not rely
	* generic/tclUtil.c (TclPrecTraceProc):	on (frequently buggy) setting
	of the TCL_INTERP_DESTROYED flag by the trace core.

	* generic/tclVar.c:	Update callers of TclCallVarTraces to not pass
	in the TCL_INTERP_DESTROYED flag. Also apply filters so that public
	routines only pass documented flag values down to lower level routines

	* generic/tclTrace.c (TclCallVarTraces):	The setting of the
	TCL_INTERP_DESTROYED flag is now done entirely within the
	TclCallVarTraces routine, the only place it can be done right.

2007-05-06  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclInt.h (ExtraFrameInfo): Create a new mechanism for
	* generic/tclCmdIL.c (InfoFrameCmd): conveying what information needs
	to be added to the results of [info frame] to replace the hack that
	was there before.
	* generic/tclProc.c (Tcl_ApplyObjCmd): Use the new mechanism for the
	[apply] command, the only part of Tcl itself that needs it (so far).

	* generic/tclInt.decls (TclEvalObjEx, TclGetSrcInfoForPc): Expose
	these two functions through the internal stubs table, necessary for
	extensions that need to integrate deeply with TIP#280.

2007-05-05  Donal K. Fellows  <dkf@users.sf.net>

	* win/tclWinFile.c (TclpGetUserHome):	Squelch type-pun warnings in
	* win/tclWinInit.c (TclpSetVariables):	Win-specific code not found
	* win/tclWinReg.c (AppendSystemError):	during earlier work on Unix.

2007-05-04  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclIO.c (TclFinalizeIOSubsystem): Added an initializer to
	silence a spurious gcc warning about use of an uninitialized
	variable.
	* tests/encoding.test: Modified so that encoding tests happen in a
	private namespace, to avoid polluting the global one. This problem was
	discovered when running the test suite '-singleproc 1 -skip exec.test'
	because the 'path' variable in encoding.test conflicted with the one
	in io.test.
	* tests/io.test: Made more of the working variables private to the
	namespace.

2007-05-02  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclTest.c (SimpleMatchInDirectory): Corrected a refcount
	imbalance that affected the filesystem-[147]* tests in the test suite.
	Thanks to Don Porter for the patch. [Bug 1710707]
	* generic/tclPathObj.c (Tcl_FSJoinPath, Tcl_FSGetNormalizedPath):
	Corrected several memory leaks that caused refcount imbalances
	resulting in memory leaks on Windows. Thanks to Joe Mistachkin for the
	patch.

2007-05-01  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclVar.c (TclPtrSetVar): fixed leak whenever newvaluePtr had
	refCount 0 and was used for appending (but not lappending). [Bug
	1710710], thanks to mistachkin and kbk.

2007-05-01  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclIO.c (DeleteChannelTable): Made changes so that
	DeleteChannelTable tries to close all open channels, not just the
	first. [Bug 1710285]
	* generic/tclThread.c (TclFinalizeSynchronization): Make sure that TSD
	blocks get freed on non-threaded builds. [Bug 1710825]
	* tests/utf.test (utf-25.1--utf-25.4): Modified tests to clean up
	after the 'testobj' extension to avoid spurious reports of memory
	leaks.

2007-05-01  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCmdMZ.c (STR_MAP):	When [string map] has a pure dict map,
	a missing Tcl_DictObjDone() call led to a memleak. [Bug 1710709]

2007-04-30  Daniel Steffen  <das@users.sourceforge.net>

	* unix/Makefile.in: add 'tclsh' dependency to install targets that
	rely on tclsh, fixes parallel 'make install' from empty build dir.

2007-04-30  Andreas Kupries <andreask@gactivestate.com>

	* generic/tclIO.c (FixLevelCode): Corrected reference count
	mismanagement of newlevel, newcode. Changed to allocate the Tcl_Obj's
	as late as possible, and only when actually needed. [Bug 1705778, leak
	K29]

2007-04-30  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclProc.c (Tcl_ProcObjCmd, SetLambdaFromAny): Corrected
	reference count mismanagement on the name of the source file in the
	TIP 280 code. [Bug 1705778, leak K02 among other manifestations]

2007-04-25  Donal K. Fellows  <dkf@users.sf.net>

	*** 8.5a6 TAGGED FOR RELEASE ***

	* generic/tclProc.c (TclObjInterpProcCore): Only allocate objects for
	error message generation when associated with argument names that are
	really used. [Bug 1705778, leak K15]

2007-04-25  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclIOUtil.c (Tcl_FSChdir): Changed the memory management so
	that the path returned from Tcl_FSGetNativePath is not duplicated
	before being stored as the current directory, to avoid a memory leak.
	[Bug 1705778, leak K01 among other manifestations]

2007-04-25  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompExpr.c (ParseExpr):	Revised to be sure that an
	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>

	* unix/Makefile.in (dist): add macosx/*.xcconfig files to src dist;
	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]
	(DictFilterCmd): Added code to drop the lock in the trivial match
	case. [Bug 1705778, leak K05]

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

	* generic/tclBinary.c: Addressed several code paths where the error
	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>

	* generic/tclCompExpr.c (ParseExpr): Memory leak in error case; the
	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.
	* generic/tclIOCmd.c (Tcl_ReadObjCmd): Plugged a leak of the buffer
	object if the physical read returned an error and the bypass area had
	no message.
	* generic/tclIORChan.c (TclChanCreateObjCmd): Plugged a leak of the
	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>

	* generic/tclCkalloc.c: fix warnings from gcc build configured with
	* generic/tclCompile.c: --enable-64bit --enable-symbols=all.
	* generic/tclExecute.c:

	* unix/tclUnixFCmd.c: add workaround for crashing bug in fts_open()

	* macosx/Tcl-Common.xcconfig: enable more warnings.

	* macosx/Tcl.xcodeproj/project.pbxproj: add 'DebugMemCompile' build
	configuration that calls configure with --enable-symbols=all; override
	configure check for __attribute__((__visibility__("hidden"))) in Debug
	configuration to restore availability of ZeroLink.

	* macosx/tclMacOSXNotify.c: fix warnings.

	* macosx/tclMacOSXFCmd.c: const fixes.

	* unix/configure: autoconf-2.59

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
	extCmdMapPtr was not being freed [Bug 1705778, leak #1].

2007-04-23  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclCompCmds.c (TclCompileUpvarCmd): Plugged a memory leak in
	'upvar' when compiling (a) upvar outside a proc, (b) upvar with a
	syntax error, or (c) upvar where the frame index is not known at
	compile time.
	* generic/tclCompExpr.c (ParseExpr): Plugged a memory leak when
	parsing expressions that contain syntax errors.
	* generic/tclEnv.c (ReplaceString): Clear memory correctly when
	growing the cache to avoid reads of uninitialised data.
	* generic/tclIORChan.c (TclChanCreateObjCmd, FreeReflectedChannel):
	Plugged two memory leaks.
	* generic/tclStrToD.c (AccumulateDecimalDigit): Fixed a mistake where

	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
	calendar.
	Deleted an entirely superfluous (and also incorrect) remark about the
	effect of Daylight Saving Time on relative times in [clock scan]. [Bug
	1582951]
	* library/clock.tcl: Corrected an error in skipping over the %Ey field
	on input.
	* library/msgs/ja.msg:
	* tools/loadICU.tcl: Corrected several localisation faults in the
	Japanese locale (most notably, incorrect dates for the Emperors'
	eras). [Bug 1637471]. Many thanks to SourceForge user 'nyademo' for
	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.
	* doc/Notifier.3: Documented Tcl_SetNotifier and Tcl_ServiceModeHook.
	Quite against my better judgment. [Bug 414933]

	* generic/regc_locale.c: Improve the const-correctness of the RE
	compiler.

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
	clear.

	* 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
	namespace.
	* doc/clock.n: Clarified the cases in which legacy time zone is
	recognized. [Bug 1656002]

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

	* generic/tclExecute.c: fixed checkInterp logic [Bug 1702212]

2007-04-16  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCompCmds.c: added a cast to silence a compiler error on
	VC2005.
	* library/clock.tcl: Restored unique-prefix matching of keywords on
	the [clock] command. [Bug 1690041]
	* tests/clock.test: Added rudimentary test cases for unique-prefix
	matching of keywords.

2007-04-14  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: removed some code at INST_EXPAND_SKTOP that
	duplicates functionality already present at checkForCatch.

2007-04-12  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: new macros OBJ_AT_TOS, OBJ_UNDER_TOS,
	OBJ_AT_DEPTH(n) and CURR_DEPTH that remove all direct references to
	tosPtr from TEBC (after initialisation and the code at the label
	cleanupV_pushObjResultPtr).

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>

	* generic/tclCompile (tclInstructionTable): Fixed bugs in description
	of dict instructions.

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

	* generic/tclCompile (tclInstructionTable): Fixed bug in description

	* generic/tclNamespace.c (NsEnsembleImplementationCmd):
	* generic/tclProc.c (InitCompiledLocals, ObjInterpProcEx)
	(TclObjInterpProcCore, ProcCompileProc): Code reordering to reduce
	branching and improve branch prediction (assume that forward branches
	are typically not taken).

2007-04-03  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: INST_INVOKE optimisation. [Patch 1693802]

2007-04-03  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclNamesp.c:	Revised ErrorCodeRead and ErrorInfoRead trace
	routines so they guarantee the ::errorCode and ::errorInfo variable
	always appear to exist. [Bug 1693252]

2007-04-03  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclInt.decls:  Moved TclGetNamespaceFromObj() to the
	* generic/tclInt.h:      internal stubs table; regen.
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c:

2007-04-02  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:     Added bytecode compilers for the variable
	* generic/tclCompCmds.c:  linking commands: 'global', 'variable',
	* generic/tclCompile.h:   'upvar', 'namespace upvar' [Patch 1688593]
	* generic/tclExecute.c:
	* generic/tclInt.h:
	* generic/tclVar.c:

2007-04-02  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Replace arrays on the C stack and ckalloc
	* generic/tclExecute.c:	calls with TclStackAlloc calls to use memory
	* generic/tclFCmd.c:	on Tcl's evaluation stack.
	* generic/tclFileName.c:
	* generic/tclIOCmd.c:
	* generic/tclIndexObj.c:
	* generic/tclInterp.c:
	* generic/tclNamesp.c:
	* generic/tclTrace.c:
	* unix/tclUnixPipe.c:

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.

	* generic/tclCmdMZ.c:	Revised [string to* $s $first $last]
	implementation to reduce number of allocs/copies.

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

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

	* generic/tclExecute.c: optimise the lookup of elements of indexed
	arrays.

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]

2007-03-23  Kevin B. Kenny  <kennykb@acm.org>

	* win/Makefile.in: Added code to keep a Cygwin path name from leaking
	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:
	* generic/tclNamesp.c:
	* generic/tclParse.c:
	* generic/tclPreserve.c:
	* generic/tclStringObj.c:
	* generic/tclUtil.c:

2007-03-20  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclEnv.c:	Some more ckalloc -> ckrealloc replacements.
	* generic/tclLink.c:

2007-03-20  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclDate.c: Rebuilt, despite Donal Fellows's comment when
	committing it that no rebuild was required.
	* generic/tclGetDate.y: According to Donal Fellows, "Introduce modern
	formatting standards; no need for rebuild of tclDate.c."

	* generic/tclListObj.c (TclLsetList, TclLsetFlat):
	* tests/lset.test: Changes to deal with shared internal representation
	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
	* generic/tclEvent.c (Tcl_CreateThread):	Tcl_Alloc() with calls
	* generic/tclObj.c (UpdateStringOfBignum):	to ckalloc(), which
	* unix/tclUnixTime.c (SetTZIfNecessary):	better supports memory
	* win/tclAppInit.c (setargv):			debugging.

2007-03-19  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* doc/regsub.n: Corrected example so that it doesn't recommend
	potentially unsafe practice. Many thanks to Konstantin Kushnir
	<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
	names correctly, so that Unicode names exceeding 127 chars can be
	retrieved without crashing. [Bug 1682211]
	* tests/registry.test (registry-4.9): Added test case for the above
	bug.

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]

	* generic/tclNamesp.c (NsEnsembleImplementationCmd):	Make efficient
	* 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
	avoid crash due to shimmering invalidating pointers. [Bug 1669489]

2007-03-12  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Fix problems with declaration
	positioning and memory leaks. [Bug 1679072]

2007-03-11  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdIL.c (Tcl_LreverseObjCmd): Ensure that a list is
	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.

2007-03-09  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCmdIL.c (Tcl_LsortObjCmd): Handle tricky case with loss
	* tests/cmdIL.test (cmdIL-1.29):	of list rep during sorting due
	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.
	* tests/clock.test: Added rudimentary test cases for 'zoneinfo'
	parsing. Adjusted several tests that depended on obsolete US DST
	transition rules.

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

	* macosx/tclMacOSXNotify.c: add spinlock debugging and sanity checks.

	* 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]
	operations.

	* 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]

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

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).

	* generic/tclExecute.c (TclExecuteByteCode): Rewrote the compiled
	* generic/tclCompCmds.c (TclCompileDictCmd): [dict update] so that it
	* generic/tclCompile.h (DictUpdateInfo):     stores critical
	* tests/dict.test (dict-21.{14,15}):	     non-varying data in an
	aux-data value instead of a (shimmerable) literal. [Bug 1671001]

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.

2007-03-01  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCompCmds.c (TclCompileForeachCmd): Prevent an unexpected
	* tests/foreach.test (foreach-9.1):		infinite loop when the
	variable list is empty and the foreach is compiled. [Bug 1671138]

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.

2007-02-20  Jan Nijtmans  <nijtmans@users.sf.net>

	* generic/tclInt.decls: Added "const" specifiers in TclSockGetPort
	* generic/tclIntDecls.h: regenerated
	* generic/*.c:
	* unix/tclUnixChan.c
	* unix/tclUnixPipe.c
	* win/tclWinPipe.c
	* win/tclWinSock.c: Added many "const" specifiers in implementation.

2007-02-20  Don Porter  <dgp@users.sourceforge.net>

	* doc/tcltest.n:        Typo fix.  [Bug 1663539]

2007-02-20  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* generic/tclFileName.c:  [Bug 1479814]. Handle extended paths
	* generic/tclPathObj.c:   on Windows NT and above. These have a
	* win/tclWinFile.c:       \\?\ prefix.
	* tests/winFCmd.test:     Tests for extended path handling.

2007-02-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tcl.m4: use SHLIB_SUFFIX=".so" on HP-UX ia64 arch.
	* unix/configure: autoconf-2.59

	* generic/tclIOUtil.c (Tcl_FSEvalFileEx): safe incr of objPtr ref.

2007-02-18  Donal K. Fellows  <dkf@users.sf.net>

	* doc/refchan.n, doc/regsub.n, doc/scan.n, doc/tclvars.n, doc/tm.n:
	* doc/unload.n: Apply [Bug 1610310] to fix typos. Thanks to Larry
	Virden for spotting them.

	* doc/interp.n: Partial fix of [Bug 1662436]; rest requires some
	policy decisions on what should and shouldn't be safe commands from
	the "new in 8.5" set.

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.

2007-02-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* doc/re_syntax.n: Corrected description of 'print' class [Bug
	1614687] and enhanced description of 'graph' class.

2007-02-12  Kevin B. Kenny  <kennykb@acm.org>

	* 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,
	1609936, 1656265]

2007-02-09  Joe Mistachkin  <joe@mistachkin.com>

	* win/nmakehlp.c: Properly cleanup after nmakehlp, including the
	* win/makefile.vc: vcX0.pch file.

2007-02-08  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclUnixInit.c (TclpCheckStackSpace): do stack size checks with
	unsigned size_t to correctly validate stackSize in the 2^31+ range.
	[Bug 1654104]

2007-02-08  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclNamesp.c:	Corrected broken logic in Tcl_DeleteNamespace()
	* tests/namespace.test:	introduced in Patch 1577278 that caused
	[namespace delete ::] to be effective only at level #0. New test
	namespace-7.7 should prevent similar error in the future. [Bug 1655305]

2007-02-06  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclNamesp.c:	Corrected broken implementation of the
	* tests/namespace.test:	TclMatchIsTrivial optimization on [namespace
	children $namespace $pattern].

2007-02-04  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4: use gcc4's __attribute__((__visibility__("hidden"))) if
	available to define MODULE_SCOPE effective on all platforms.
	* unix/configure.in: add caching to -pipe and zoneinfo checks.
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

2007-02-03  Joe Mistachkin  <joe@mistachkin.com>

	* win/rules.vc: Fix platform specific file copy macros for downlevel
	Windows.

2007-01-29  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclResult.c: Added optimization case to TclTransferResult to
	cover common case where there's big savings over the fully general
	path. Thanks to Peter MacDonald. [Bug 1626518].

	* generic/tclLink.c:	Broken linked float logic corrected. Thanks to
	Andy Goth. [Bug 1602538]

	* doc/fcopy.n:	Typo fix. [Bug 1630627]

2007-01-28  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/Tcl.xcodeproj/project.pbxproj:   extract build settings that
	* macosx/Tcl.xcodeproj/default.pbxuser:   were common to multiple
	* macosx/Tcl-Common.xcconfig (new file):  configurations into external
	* macosx/Tcl-Debug.xcconfig (new file):   xcconfig files; add extra
	* macosx/Tcl-Release.xcconfig (new file): configurations for building
	with SDKs and 64bit; convert legacy jam-based 'Tcl' target to native
	target with single script phase; correct syntax of build setting
	references to use $() throughout.

	* macosx/README: document new Tcl.xcodeproj configurations; other minor
	updates/corrections.

	* generic/tcl.h: update location of version numbers in macosx files.

	changes to Tcl.xcodeproj since 2006-07-20.

2007-01-25  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4: integrate CPPFLAGS into CFLAGS as late as possible and
	move (rather than duplicate) -isysroot flags from CFLAGS to CPPFLAGS
	to avoid errors about multiple -isysroot flags from some older gcc
	builds.

	* unix/configure: autoconf-2.59

2007-01-22  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* compat/memcmp.c (memcmp): Reworked so that arithmetic is never
	performed upon void pointers, since that is illegal. [Bug 1631017]

2007-01-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCompile.c (TclCompileScript): Reduce the frequency with
	which we issue INST_START_CMD, making bytecode both more compact and
	somewhat faster. The optimized case is where we would otherwise be
	issuing a sequence of those instructions; in those cases, it is only
	ever the first one encountered that could possibly trigger.

2007-01-19  Joe Mistachkin  <joe@mistachkin.com>

	* tools/man2tcl.c: Include stdlib.h for exit() and improve comment
	detection.
	* win/nmakehlp.c: Update usage.
	* win/makefile.vc: Properly build man2tcl.c for MSVC8.

2007-01-19  Daniel Steffen  <das@users.sourceforge.net>

	* macosx/tclMacOSXFCmd.c (TclMacOSXSetFileAttribute): on some versions
	of Mac OS X, truncate() fails on resource forks, in that case use
	open() with O_TRUNC instead.

	* macosx/tclMacOSXNotify.c: accommodate changes to prototypes of
	OSSpinLock(Un)Lock API.

	* macosx/Tcl.xcodeproj/project.pbxproj: ensure HOME and USER env vars

	                                        testsuite from Xcode.

	* tests/env.test: add extra system env vars that need to be preserved
	on some Mac OS X versions for testsuite to work.

	* unix/Makefile.in:  Move libtommath defines into configure.in to
	* 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.

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

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

	* generic/tclCompile.c (TclCompileScript): Make sure that when parsing
	an expanded literal fails, a correct bytecode sequence is still
	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]

2007-01-17  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclIO.c: Added macros to make usage of ChannelBuffers
	clearer.

2007-01-11  Joe English  <jenglish@users.sourceforge.net>

	* win/tcl.m4(CFLAGS_WARNING): Remove "-Wconversion". This was removed
	from unix/tcl.m4 2004-07-16 but not from here.
	* win/configure: Regenerated.

2007-01-11  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/makefile.vc: Fixes to work better on Win98. Read version numbers
	* win/nmakehlp.c:  from package index file to avoid keeping numbers in
	* win/rules.vc:    the makefile where they may become de-synchronized.

	* generic/regguts.h (AllocVars, FreeVars):   of the RE engine to reduce
	* generic/regcustom.h (AllocVars, FreeVars): C stack usage. This will
	make Tcl as a whole much less likely to run out of stack space...

2007-01-09  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclCompCmds.c (TclCompileLindexCmd):
	* tests/lindex.test (lindex-9.2): Fix silly bug that ended up
	sometimes compiling list arguments in the wrong order. [Bug 1631364]

2007-01-03  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclDate.c: Regenerated to recover a lost fix from patthoyts.
	[Bug 1618523]

2006-12-26  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclIO.c (Tcl_GetsObj): Avoid checking for for the LF in a
	possible CRLF sequence when EOF has already been found.

2006-12-26  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclEncoding.c (EscapeFromUtfProc): Clear the
	TCL_ENCODING_END flag when end bytes are written. This fix keep this
	method from writing escape bytes for an encoding like iso2022-jp
	multiple times when the escape byte overlap with the end of the IO
	buffer.
	* tests/io.test: Add test for escape byte overlap issue.

2006-12-19  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* unix/tclUnixThrd.c (Tcl_GetAllocMutex, TclpNewAllocMutex): Add
	intermediate variables to shut up unwanted warnings. [Bug 1618838]

2006-12-19  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclUnixThrd.c (TclpInetNtoa): fix for 64 bit.

	* unix/tcl.m4 (Darwin): --enable-64bit: verify linking with 64bit -arch
	flag succeeds before enabling 64bit build.
	* unix/configure: autoconf-2.59

2006-12-17  Daniel Steffen  <das@users.sourceforge.net>

	* tests/macOSXLoad.test (new file): add testing of .bundle loading and
	* tests/load.test:		    unloading on Darwin (in addition to
	* tests/unload.test:		    existing tests of .dylib loading).
	* macosx/Tcl.xcodeproj/project.pbxproj: add building of dltest binaries
	so that testsuite run from Xcode can use them; fix testsuite run script
	* unix/configure.in:	   add support for building dltest binaries as
	* unix/dltest/Makefile.in: .bundle (in addition to .dylib) on Darwin.
	* unix/Makefile.in: add stub lib dependency to dltest target.
	* unix/configure: autoconf-2.59

	* tests/append.test: fix cleanup failure when all tests are skipped.

	* tests/chan.test (chan-16.9): cleanup chan event handler to avoid
	causing error in event.test when running testsuite with -singleproc 1.

	* tests/info.test: add !singleTestInterp constraint to tests that fail
	when running testsuite with -singleproc 1. [Bug 1605269]

2006-12-14  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* 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
	removed.

	* 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 commands
	* generic/tclCompExpr.c: 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.
	* tests/mathop.test:

2006-12-08  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclNamesp.c (TclTeardownNamespace): Ensure that dying
	namespaces unstitch themselves from their referents. [Bug 1571056]
	(NsEnsembleImplementationCmd): Silence GCC warning.

	* tests/mathop.test: Full tests for & | and ^ operators

2006-12-08  Daniel Steffen  <das@users.sourceforge.net>

	* library/tcltest/tcltest.tcl: use [info frame] for "-verbose line".

2006-12-07  Don Porter  <dgp@users.sourceforge.net>

	* 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.
	* generic/tclMathOp.c (TclInvertOpCmd): Add in check for non-integral
	numeric values.
	* generic/tclCompCmds.c (CompileCompareOpCmd): Factor out the code
	generation for the chained comparison operators.

2006-12-07  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* tests/exec.test: Fixed line endings (caused win32 problems).

2006-12-06  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompCmds.c:	Revised and consolidated into utility
	* tests/mathop.test:		routines some of routines that compile
	the new TIP 174 commands. This corrects some known bugs. More to come.

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

	* tests/expr.test (expr-47.12): Improved error reporting in hopes of
	having more information to pursue [Bug 1609936].

2006-12-05  Andreas Kupries  <andreask@activestate.com>

2006-12-05  Don Porter  <dgp@users.sourceforge.net>

	* 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.

2006-12-04  Donal K. Fellows  <dkf@users.sf.net>

	TIP#267 IMPLEMENTATION

	* generic/tclIOCmd.c (Tcl_ExecObjCmd): Added -ignorestderr option,
	* tests/exec.test, doc/exec.n:	       loosely from [Patch 1476191]

2006-12-04  Don Porter  <dgp@users.sourceforge.net>

	* 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.

2006-12-02  Donal K. Fellows  <dkf@users.sf.net>

	* libtommath/bn_mp_add.c:	Corrected the effects of a
	* libtommath/bn_mp_div.c:	bollixed 'cvs merge' operation
	* libtommath/bncore.c:		that inadvertently committed some
	* libtommath/tommath_class.h:	half-developed code.

	TIP#299 IMPLEMENTATION

	* doc/mathfunc.n:	Added isqrt() function to docs
	* generic/tclBasic.c:	Added isqrt() math function (ExprIsqrtFunc)

	* library/tzdata: Olson's tzdata2006p.
	* libtommath/bn_mp_sqrt.c: Fixed a bug where the initial approximation
	to the square root could be on the wrong side, causing failure of
	convergence.

2006-11-29  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclBasic.c (Tcl_AppendObjToErrorInfo):  Added
	Tcl_DecrRefCount() on the objPtr argument to plug memory leaks. This
	makes the routine a consumer, which makes it easiest to use.

	* generic/tclInt.h, generic/tclInt.decls: Transfer TclPtrMakeUpvar and
	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.

	* doc/string.n:				    from TIP#272.

	* generic/tclCmdIL.c (Tcl_LreverseObjCmd): 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.

	TIP#274 IMPLEMENTATION

	* 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
	* tests/unixInit.test (unixInit-1.2):	systems (e.g., Windows).

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

	* macosx/Tcl.xcodeproj/project.pbxproj: check autoconf/autoheader exit
	status and stop build if they fail.

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

	* generic/tclBasic.c, generic/tclInterp.c, generic/tclProc.c: Silence

	* 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, rather
	* generic/tclCmdIL.c:	than report an error message.  This means an

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>

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
	TCL_EVAL_NOREWRITE for aliases.

	* 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].

	***POTENTIAL INCOMPATIBILITY***
	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).

	***POTENTIAL INCOMPATIBILITY***
	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).

	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

	* unix/tclUnixThrd.c (TclpThreadGetStackSize): Darwin: fix for main
	thread, where pthread_get_stacksize_np() returns incorrect info.

	* macosx/GNUmakefile: don't redo prebinding of non-prebound binaires.

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

	* win/tclWinFile.c: alfredd supplied patch to fix [Bug 1575837]

2006-10-12  David Gravereaux <davygrvy@pobox.com>

	* win/nmakehlp.c: Replaced all wnsprintf() calls with snprintf().

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,

	* tests/cmdAH.test:	        directories on windows

	* tests/winFile.test: Handle Msys environment a little differently in
	getuser function. Fix for [Bug 1567956].

2006-09-30  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclUtil.c (Tcl_SplitList): optimisation, [Patch 1344747] by
	dgp.

	* 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
	1512138]

	* 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
	tclCompile.c

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. See
	[Bug 1563836].

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
	REGEXP_MCCE_ENABLE.
	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: [Bug 1563836]. 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.

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
	changes.

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>

	TIP#268 IMPLEMENTATION

	* library/tm.tcl:

2006-09-22  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* 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
	* library/http/pkgIndex.tcl:  to " " -> "%20" as per RFC 3986.
	* tests/http.test (http-5.1): bump http to 2.5.3
	* unix/Makefile.in:
	* win/Makefile.in:

2006-09-12  Andreas Kupries  <andreask@activestate.com>

	* unix/configure.in (HAVE_MTSAFE_GETHOST*): Modified to recognize
	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 ->
	2.3.0.

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
	* win/Makefile.in:	consistent with dgp's commits of 2006-09-10.

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/tcltest/pkgIndex.tcl: account	for new "-verbose line"
	* library/tcltest/tcltest.tcl:  feature.
	* unix/Makefile.in:
	* win/Makefile.in:
	* win/makefile.bc:
	* win/makefile.vc:

	* library/msgcat/msgcat.tcl:	Bump to version msgcat 1.4.2 to account
	* library/msgcat/pkgIndex.tcl:	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
	* unix/tclUnixCompat.c: TSD storage making them all look like their
	* unix/tclUnixFCmd.c:   MT-unsafe pendants API-wise.
	* unix/tclUnixPort.h:
	* unix/tclUnixSock.c:

2006-09-06  Zoran Vasiljevic <vasiljevic@users.sourceforge.net>

	* unix/tclUnixChan.c: Added TCL_THREADS ifdef'ed usage of MT-safe
	* unix/tclUnixFCmd.c: calls like: getpwuid, getpwnam, getgrgid,
	* unix/tclUnixSock.c: getgrnam, gethostbyname and gethostbyaddr.
	* unix/tclUnixPort.h: See [Bug 999544]
	* unix/Makefile.in:
	* unix/configure.in:
	* unix/tcl.m4:
	* unix/configure: Regenerated.

	* unix/tclUnixCompat.c: New file containing MT-safe implementation of
	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>

	* generic/tclBasic.c (Tcl_CreateInterp): init iPtr->threadId

	* win/tclWinChan.c [Bug 819667] Improve logic for identifying COM
	ports.

	* 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
	VALGRIND_OPTS env var.

	* 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
	* generic/tclPathObj.c: Tcl_FSGetNormalizedPath which was causing
	* unix/tclUnixFile.c:   segv's per [Bug 1548263]
	* win/tclWinFCmd.c:
	* win/tclWinFile.c:

2006-08-28  Kevin B. Kenny  <kennykb@acm.org>

	* library/tzdata/America/Havana:      Regenerated from Olson's
	* library/tzdata/America/Tegucigalpa: tzdata2006k.
	* library/tzdata/Asia/Gaza:

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
	1547786]

	* 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
	Duquette.

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
	* tests/compExpr.test:		with the new expr parser.
	* tests/compile.test:
	* tests/expr-old.test:
	* tests/expr.test:
	* tests/for.test:
	* tests/if.test:

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

	* generic/tcl.h:          add fixes for building on Leopard and support
	* unix/tclUnixPort.h:     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 changes
	* macosx/README: updates for x86_64 and Xcode 2.4.

	* macosx/Tcl.xcodeproj/default.pbxuser: add test suite target that runs
	* macosx/Tcl.xcodeproj/project.pbxproj: the tcl test suite at build
	time and shows clickable test suite errors in the GUI build window.

	* 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.

2006-08-17  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclCompile.c:		Revised the new set of expression parse
	* generic/tclParseExpr.c:	error messages.

2006-08-16  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclParseExpr.c:	Replace PrecedenceOf() function with
	prec[] static array.

2006-08-14  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* library/clock.tcl (::tcl::clock::add): Added missing braces to
	clockval validation code. Pointed out on comp.lang.tcl.

2006-08-11  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclNamesp.c: Improvements in buffer management to make
	namespace creation faster. Plus selected other minor improvements to
	code quality. [Patch 1352382]

2006-08-10  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	Misc patches to make code more efficient. [Bug 1530474] (afredd)
	* generic/*.c, macosx/tclMacOSXNotify.c, unix/tclUnixNotfy.c,
	* win/tclWinThrd.c: Tidy up invokations of Tcl_Panic() to promote
	string constant sharing and consistent style.
	* generic/tclBasic.c (Tcl_CreateInterp): More efficient handling of
	* generic/tclClock.c (TclClockInit):     registration of commands not
						 in global namespace.
	* generic/tclVar.c (Tcl_UnsetObjCmd): Remove unreachable clause.

2006-08-09  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclEncoding.c:        Replace buffer copy in for loop
        with call to memcpy().  Thanks to afredd. [Patch 1530262]

2006-08-09  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclCmdIL.c (Tcl_LassignObjCmd): Make the wrong#args message a
	bit more consistent with those used elsewhere. [Bug 1534628]

	* generic/tclDictObj.c (DictForCmd): Stop crash when attempting to
	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
	1526581]

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 error
	* tests/compile.test:      messages of the pre-2006-07-05 expression
	* tests/expr-old.test:     parser. The constraint is on by default (i.e
	* tests/expr.test:         those tests still fail), but can be turned
	* tests/for.test:          off by passing '-constraints newExprParser'
	* tests/if.test:           to tcltest, which will skip the 196 failing
	* tests/parseExpr.test:    tests in the testsuite that are caused by
	* tests/while.test:        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 once
	* unix/tclUnixFCmd.c (DoRenameFile, TclpObjNormalizePath): add runtime
	Darwin release check to determine if realpath is threadsafe.
	* unix/configure.in: add check on Darwin for compiler support of weak
	* unix/tcl.m4:       import and for AvailabilityMacros.h header; move
	Darwin specific checks & defines that are only relevant to the tcl
	build out of tcl.m4; restrict framework option to Darwin; 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/tclParseExpr.c (Tcl_ParseExpr):
	* generic/tclStrToD.c (TclParseNumber):
	* generic/tclStringObj.c (TclAppendFormattedObjs):
	* unix/tclLoadDyld.c (TclpLoadMemory):
	* unix/tclUnixPipe.c (TclpCreateProcess): fix signed-with-unsigned
	comparison and other warnings from gcc4 -Wextra.

2006-07-13  Andreas Kupries <andreask@activestate.com>

	* unix/tclUnixPort.h: Added the inclusion of <AvailabilityMacros.h>.
	The missing header caused the upcoming #if conditions to wrongly
	exclude realpath, causing file normalize to ignore symbolic links in
	the path.

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

	* generic/tclAsync.c: Made Tcl_AsyncDelete() more tolerant when called
	after all thread TSD has been garbage-collected.

2006-07-05  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclParseExpr.c:	Completely new expression parser that
	builds a parse tree instead of operating with deep recursion. This
	corrects reports of stack-blowing crashes parsing long expressions [Bug
	906201] and replaces a fundamentally O(N^2) algorithm with an O(N) one
	[RFE 903765]. The new parser is better able to generate error messages
	that clearly report both the nature and context of the syntax error
	[Bugs 1029267, 1381715]. For now, the code for the old parser is still
	present and can be activated with a "#define OLD_EXPR_PARSER 1". This
	is for the sake of a clean implementation patch, and for ease of
	benchmarking. The new parser is non-recursive, so much lighter in stack
	consumption, but it does use more heap, so there may be cases where
	parsing of long expressions that succeeded with the old parser will
	lead to out of memory panics with the new one. There are still more
	improvements possible on that point, though significant progress may
	require changes to the Tcl_Token specifications documented for the
	public Tcl_Parse*() routines.
	***POTENTIAL INCOMPATIBILITY*** for any callers that rely on the exact
	(usually terrible) error messages generated by the old parser. This
	includes a large number of tests in the test suite.

	* generic/tclInt.h:		Replaced TclParseWhiteSpace() with
	* generic/tclParse.c:		TclParseAllWhiteSpace() which is what
	* generic/tclParseExpr.c:	all the callers really needed. Breaking
	whitespace runs at newlines is useful only to the command parsing
	function, and it can call the file scoped routine ParseWhiteSpace() to
	do that.

	* tests/expr-old.test:	Removed knownBug constraints that masked
	* tests/expr.test:	failures due to revised error messages.
	* tests/parseExpr.test:

2006-06-20  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclIOUtil.c:	Changed default configuration to
	* generic/tclInt.decls:	#undef USE_OBSOLETE_FS_HOOKS which disables
	* generic/tclTest.c:	access to the Tcl 8.3 internal routines for
	hooking into filesystem operations. Everyone ought to have migrated to
	Tcl_Filesystems by now.
	***POTENTIAL INCOMPATIBILITY*** for any code still stuck in the
	pre-Tcl_Filesystem era.

	* generic/tclIntDecls.h:	make genstubs
	* generic/tclStubInit.c:

	* generic/tclStrToD.c:	Removed dead code that permitted disabling of
	recognition of the new 0b and 0o numeric formats.

	* generic/tclExecute.c:	Removed dead code that implemented alternative
	* generic/tclObj.c:	design where numeric values did not
	automatically narrow to the smallest Tcl_ObjType required to hold them.

	* generic/tclCmdAH.c:	Removed dead code that was old implementation
	of [format].

2006-06-14  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclUnixPort.h (Darwin): support for MAC_OS_X_VERSION_MAX_ALLOWED
	define from AvailabilityMacros.h: override configure detection and only
	use API available in the indicated OS version or earlier.

2006-06-14  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* doc/format.n, doc/scan.n: Added examples for converting between
	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].

2006-05-04  Don Porter  <dgp@users.sourceforge.net>

	* tests/scan.test:	decimal formatted integers. Fixed to match.

2006-04-19  Kevin B. Kenny  <kennykb@acm.org>

	* 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
	http://wiki.tcl.tk/15408.
	* library/clock.tcl: Fixed a bug with Daylight Saving Time and Posix
	time zone specifiers reported by Martin Lemburg in
	http://groups.google.com/group/comp.lang.tcl/browse_thread/thread/9a8b15a4dfc0b7a0
	(and not at SourceForge).
	* tests/clock.test: Added test case for the above bug.

2006-04-18  Donal K. Fellows  <dkf@users.sf.net>

	the behaviour of Tcl_GetBignumAndClearObj.

2006-04-17  Don Porter  <dgp@users.sourceforge.net>

	* doc/IntObj.3:	Documentation changes to account for TIP 237 changes.
	* doc/Object.3:	[Bug 1446971]

2006-04-12  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/regc_locale.c (cclass): Redefined the meaning of [:print:] to
	be exactly UNICODE letters, numbers, punctuation, symbols and spaces
	(*not* whitespace). [Bug 1376892]

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

	* generic/tclTrace.c:   Stop some interference between enter traces

	* generic/tclPathObj.c:	Yet another revised fix for the [Bug 1379287]
	* tests/fileSystem.test:	family of path normalization bugs.

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]

	* tests/compExpr-old.test:	Updated testmathfunctions constraint
	* tests/compExpr.test:		to post-TIP-232 world.
	* tests/expr-old.test:
	* tests/expr.test:
	* tests/info.test:

	* tests/indexObj.test:	Corrected other test errors revealed by
	* tests/upvar.test:	testing outside the tcltest application.

	* generic/tclPathObj.c: Revised fix for the [Bug 1379287] family of
	path normalization bugs.

2006-04-06  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4: removed TCL_IO_TRACK_OS_FOR_DRIVER_WITH_BAD_BLOCKING
	define on Darwin. [Bug 1457515]
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

2006-04-05  Don Porter  <dgp@users.sourceforge.net>

	* win/tclWinInit.c:	More careful calls to Tcl_DStringSetLength()
	* win/tclWinSock.c:	to avoid creating invalid DString states.
	* win/tclWinDde.c:	Bump to version 1.3.2. [RFE 1366195]
	* library/dde/pkgIndex.tcl:

	* library/reg/pkgIndex.tcl:	Bump to registry 1.2 because

	* win/Makefile.in:	compared to the 1.1.* releases.

	* win/configure.in:	Bump package version numbers.
	* win/configure:	autoconf 2.59

2006-04-05  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct): Allow empty
	strings to be matched by the Tcl_GetIndexFromObj machinery, in the
	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): [Bug 1462248]. 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.

	* 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].

2006-03-30  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclPathObj.c:	 More fixes for path normalization when /../
	* tests/fileSystem.test: tries to go beyond root.[Bug 1379287]

	* generic/tclExecute.c: Revised INST_MOD implementation to do
	calculations in native types as much as possible, moving to mp_ints
	only when necessary.

2006-03-28  Jeff Hobbs  <jeffh@ActiveState.com>

	* win/tclWinPipe.c (TclpCreateProcess): change panics to Tcl errors and
	do proper refcounting of noe objPtr. [Bug 1194429]

	* unix/tcl.m4, win/tcl.m4: []-quote AC_DEFUN functions.

	* macosx/Tcl.xcode/project.pbxproj:     removed $prefix/share from
	* macosx/Tcl.xcodeproj/project.pbxproj: TCL_PACKAGE_PATH as per change
	to unix/configure.in of 2006-03-13.

	* unix/tclUnixFCmd.c (TclpObjNormalizePath): deal with *BSD/Darwin
	realpath() converting relative paths into absolute paths. [Bug 1064247]

2006-03-28  Vince Darley  <vincentdarley@sourceforge.net>

	* generic/tclIOUtil.c: fix to nativeFilesystemRecord comparisons

2006-03-27  Andreas Kupries <andreask@activestate.com>

	* doc/CrtChannel.3:    Added TCL_CHANNEL_VERSION_5, made it the version
	* generic/tcl.h:       where the "truncateProc" is defined at, and
	* generic/tclIO.c:     moved all channel drivers of Tcl to v5.
	* generic/tclIOGT.c, generic/tclIORChan.c, unix/tclUnixChan.c:
	* unix/tclUnixPipe.c, win/tclWinChan.c, win/tclWinConsole.c:

2006-03-27  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c: Merge INST_MOD computation in with the
	INST_?SHIFT instructions, which also operate only on two integral
	values. Also corrected flaw that made INST_BITNOT of wide values
	require mp_int calculations. Also corrected type that missed optimized
	handling of the tclBooleanType by the TclGetBooleanFromObj macro.

	* changes:	Updates for another RC.

2006-03-25  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c: Corrections to INST_EXPON detection of overflow
	to use mp_int calculations.

2006-03-24  Kevin B. Kenny  <kennykb@acm.org>

	casts to 'int' that were affecting compilablity on VC6.

2006-03-24  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclEncoding.c: Reverted latest change [Bug 506653] since it
	reportedly killed test performance on Windows.

	* generic/tclExecute.c: Revised INST_EXPON implementation to do
	calculations in native types as much as possible, moving to mp_ints
	only when necessary.

2006-03-23  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c: Merged INST_EXPON handling in with the other
	binary operators that operate on all number types (INST_ADD, etc.).

	* tests/env.test: With case preserved (see 2006-03-21 commit) be sure
	to do case-insensitive filtering. [Bug 1457065]

2006-03-23  Reinhard Max  <max@suse.de>

	* unix/tcl.spec: Cleaned up and completed the spec file. An RPM can now
	be built from the tcl source distribution with "rpmbuild -tb <tarball>"

2006-03-22  Reinhard Max  <max@suse.de>

	* tests/stack.test: Run the stack tests in subshells, so that they are
	reported as failed tests rather than bugs in the test suite if the
	recursion causes a segfault.

2006-03-21  Don Porter  <dgp@users.sourceforge.net>

	* changes:	Updates for another RC.

	* generic/tclStrToD.c:	One of the branches of AccumulateDecimalDigit
	* tests/parseExpr.test:	did not. [Bug 1451233]

	* tests/env.test:	Preserve case of saved env vars. [Bug 1409272]

2006-03-21  Daniel Steffen  <das@users.sourceforge.net>

	* generic/tclInt.decls:  implement globbing for HFS creator & type
	* macosx/tclMacOSXFCmd.c:codes and 'hidden' flag, as documented in
	* tests/macOSXFCmd.test: glob.n; objectified OSType handling in [glob]
	* 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
	errors.

	***POTENTIAL INCOMPATIBILITY*** for scripts that assumed '-nocomplain'
	removes the need for 'catch' to deal with non-understood path names.

	Small optimisation to implementation of pattern==NULL case of TclGlob,
	and clarification to the documentation. [Tclvfs bug 1405317]

2006-03-18  Vince Darley  <vincentdarley@sourceforge.net>

	* tests/fCmd.test: added knownBug test case for [Bug 1394972]

	* tests/winFCmd.test:
	* tests/tcltest.test: corrected tests to better account for behaviour
	of writable/non-writable directories on Windows 2000/XP. This, with the
	previous patches, closes [Bug 1193497]

2006-03-17  Andreas Kupries <andreask@activestate.com>

	* doc/chan.n: Updated with documentation for the commands 'chan create'
	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
	1444692]

	* 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
	needed.
	* unix/installManpage: Reverted part to handle double-quotes in section
	NAME, chokes older sed installations.

2006-03-14  Andreas Kupries <andreask@activestate.com>

	* library/tm.tcl (::tcl::tm::Defaults): Fixed handling of environment
	variable TCLX.y_TM_PATH, bad variable reference. [Bug 1448251]. Thanks
	to Julian Noble.

2006-03-14  Vince Darley  <vincentdarley@sourceforge.net>

	* win/tclWinFile.c: updated patch to deal with 'file writable' issues
	on Windows XP/2000.
	* generic/tclTest.c:
	* unix/tclUnixTest.c:
	* win/tclWinTest.c:
	* tests/fCmd.test: updated test suite to deal with correct permissions
	setting and differences between XP/2000 and 95/98 3 tests still fail;
	to be dealt with shortly

2006-03-13  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclEncoding.c: Report error when an escape encoding is
	missing one of its sub-encodings [Bug 506653].

	* unix/configure.in:    Revert change from 2005-07-26 that sometimes
	* unix/configure:       added $prefix/share to the tcl_pkgPath. See
	[Patch 1231015]. autoconf-2.59.

2006-03-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclProc.c (ObjInterpProcEx):
	* tests/apply.test (apply-5.1): Fix [apply] error messages so that they
	quote the lambda expression [Bug 1447355].

2006-03-10  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>

	-- Summary of changes fixing [Bug 1437595] --

	* generic/tclEvent.c: Cosmetic touches and identation
	* generic/tclInt.h: Added TclpFinalizeSockets() call.

	* generic/tclIO.c: Calls TclpFinalizeSockets() as part of the
	TclFinalizeIOSubsystem().

	* unix/tclUnixSock.c: Added no-op TclpFinalizeSockets().

	* win/tclWinPipe.c, win/tclWinSock.c: Finalization of sockets/pipes is
	now solely done in TclpFinalizeSockets() and TclpFinalizePipes() and
	not over the thread-exit handler, because the order of actions the Tcl
	generic core will impose may result in cores/hangs if the thread exit
	handler tears down corresponding subsystem(s) too early.

2006-03-10  Vince Darley  <vincentdarley@sourceforge.net>

	* win/tclWinFile.c: previous patch breaks tests, so removed.

2006-03-09  Vince Darley  <vincentdarley@sourceforge.net>

	* 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

	*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 1439836].

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>

	TIP#215 IMPLEMENTATION

	* doc/incr.n:		Revised [incr] to auto-initialize when varName
	* generic/tclExecute.c:	argument is unset. [Patch 1413115].
	* generic/tclVar.c:
	* 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.

	TIP#258 IMPLEMENTATION

	* 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
	* library/init.tcl:	Removed commands:
	* tests/cmdAH.test:		[tcl::unsupported::EncodingDirs]
	* tests/encoding.test:		[testencoding path] (Tcltest)
	* unix/tclUnixInit.c:	[Patch 1413934].

	* generic/tclStubInit.c:

2006-02-01  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclProc.c: minor improvements to [apply]
	* tests/apply.test: new tests; apply-5.1 currently fails to indicate
	missing work in error reporting

2006-02-01  Don Porter  <dgp@users.sourceforge.net>

	TIP#194 IMPLEMENTATION

	* 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.n:	routines Tcl_(Get|Set)NamespaceUnknownHandler.
	* doc/unknown.n:	[Patch 958222].
	* generic/tcl.decls:
	* generic/tclBasic.c:
	* generic/tclInt.h:
	* generic/tclNamesp.c:
	* tests/namespace.test:

	* generic/tclDecls.h:	make genstubs

	* generic/tclInt.h:
	* generic/tclNamesp.c:
	* generic/tclVar.c:

	* 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 [Bug 1410553]. Thanks to twylite and Peter Spjuth.

	* 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
	places.

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.
