Tcl Source Code

2005-10-08  Don Porter  <[email protected]>

	[kennykb-numerics-branch]	Merge updates from HEAD

	* generic/tclExecute.c:	More performance macros and special
	handling of the wide integer type for performance on 32-bit
	systems.

2005-10-07  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Macro GetNumberFromObj() is version of
	TclGetNumberFromObj() that saves a function call for common uses.

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

	* generic/tclExecute.c:	Improved performance of comparison opcodes
	and bitwise operations and removed yet more dead code.

2005-10-07  Jeff Hobbs  <[email protected]>

	* unix/tclUnixFCmd.c (TraverseUnixTree): Adjust 2004-11-11 change to
	* tests/fCmd.test (fCmd-20.2):           account for NFS special
	files with a readdir rewind threshold. [Bug 1034337]

2005-10-06  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Improved performance of INST_RSHIFT and
	INST_LSHIFT.

2005-10-05  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Improved performance of INST_MULT, INST_DIV,
	INST_ADD, and INST_SUB and replaced a "goto... label" with a
	"break from loop" in TclIncrObj() and removed some dead code.

2005-10-05  Andreas Kupries <[email protected]>

	* generic/tclPipe.c (TclCreatePipeline): Fixed [SF Tcl Bug
	  1109294]. Applied the patch provided by David Gravereaux.

	* doc/CrtChannel.3: Fixed [SF Tcl Bug 1104682], by application of
	  David Welton's patch for it, and added a note about
	  wideSeekProc.

	* generic/tclIORChan.c (RcClose): Removed unreachable panic/return
	  statements. This fixes the remainder of [SF Tcl Bug 1286256].

2005-10-05  Jeff Hobbs  <[email protected]>

	* tests/env.test (env-6.1):
	* win/tclWinPort.h: define USE_PUTENV_FOR_UNSET 1
	* generic/tclEnv.c (TclSetEnv, TclUnsetEnv): add
	USE_PUTENV_FOR_UNSET to existing USE_PUTENV define to account for
	various systems that have putenv(), but can't unset env vars with
	it.  Note difference between Windows and Linux for actually
	unsetting the env var (use of '=').
	Correct the resizing of the environ array.  We assume that we are
	in full ownership, but that's not correct.[Bug 979640]

2005-10-04  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Updated TclIncrObj() to more efficiently
	add native long integers.  Also updated IllegalExprOperandType
	and the INST_UMINUS, INST_UPLUS, INST_BITNOT, and
	INST_TRY_CVT_TO_NUMERIC sections for performance.

	* generic/tclBasic.c:	Updated more callers to make use of
	TclGetNumberFromObj.  Removed some dead code.

2005-10-04  Jeff Hobbs  <[email protected]>

	* win/tclWinSerial.c (SerialSetOptionProc): free argv [Bug 1067708]

	* tests/http.test:              do not URI encode -._~ according

	* tests/winFile.test (getuser): allow valid Windows usernames.
	[Bug 1311285]

	* generic/tclParse.c (Tcl_ParseCommand): add code that recognizes
	{} in addition to {expand} for word expansion (make with
	-DALLOW_EMPTY_EXPAND).

2005-10-04  Zoran Vasiljevic <[email protected]>

	* generic/tclIO.c (Tcl_ClearChannelHandlers): now deletes any
	outstanding timer for the channel. Also, prevents events still
	in the event queue from triggering on the current channel.

	* generic/tclTimer.c (Tcl_DeleteTimerHandler): bail out early
	if passed NULL argument.

2005-10-03  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclBasic.c:	Re-implemented ExprRoundFunc and ExprEntierFunc
	to use TclGetNumberFromObj.

	* generic/tclInt.h:	Added new routine TclGetNumberFromObj to

	                      number of changes to other locales.
	* tests/clock.test:   Regenerated for new US DST rules.
	
2005-09-30  Don Porter  <[email protected]>

	* generic/tclMain.c: Separate encoding conversion of command line
	arguments from list formatting.	 [Bug 1306162].

2005-09-30  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclStringObj.c:	Bug fix: Missing cast to large enough
	integral size before << operations led to broken [format %llx] results.
	Thanks to Robert Henry for reporting the bug.

2005-09-29  Jeff Hobbs  <[email protected]>

	* doc/mathfunc.n:   implementation for TIP #255, expr min/max
	* library/init.tcl:
	* tests/info.test, tests/expr-old.test: 

2005-09-27  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tcl.h:	Changed name of the new Tcl_Obj intrep field
	* generic/tclObj.c:	from "bignumValue" to "ptrAndLongRep" as
	* generic/tclProc.c:	described in TIP 237, and more suitable for
	other more general uses.

2005-09-27  Donal K. Fellows  <[email protected]>

	* tests/binary.test (binary-14.18): Added test for [Bug 1116542]
	though the bug itself was already fixed by unrelated changes.

2005-09-26  Kevin Kenny  <[email protected]>

	[kennykb-numerics-branch] Merge updates from HEAD.
	
2005-09-26  Kevin Kenny  <[email protected]>

	* generic/tommath.h:             Regenerated.
	* generic/tclTomMathInterface.h: Added ten missing aliases for mp_*
	functions to avoid namespace pollution in Tcl's exported symbols.
	[Bug 1263012]
	
2005-09-23  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* unix/Makefile.in:	Added -DMP_PREC=4 switch to all compiles so
	* win/Makefile.in:	that minimum memory requirements of mp_int's
	* win/makefile.vc:	will not be quite so large.  [Bug 1299153].

	* generic/tclStrToD.c:	Fixed memory leak.  [Bug 1299803].
	* generic/tclObj.c:	

2005-09-20  Don Porter  <[email protected]>

	[kennykb-numerics-branch]
	
	* generic/tclExecute.c:	Revise TclIncrObj() to call
	Tcl_GetBignumAndClearObj.

	* generic/tcl.decls:	Add Tcl_GetBignumAndClearObj.
	* generic/tclObj.c:

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

2005-09-16  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclInt.h:		Added TclBNInitBigNumFromWideInt()
	* generic/tclTomMathInterface.c:	so that every caller isn't
	required to duplicate the sign logic to use the unsigned interface.

	* generic/tclBasic.c:	Reduce the number of places where Tcl
	* generic/tclExecute.c:	intrudes into the internal format details
	* generic/tclObj.c:	of the mp_int struct.
	* generic/tclStrToD.c:
	* generic/tcLStringObj.c:

	* generic/tclTomMath.h:	Added mp_cmp_d to routines from
	* unix/Makefile.in:	libtommath used by Tcl.
	* win/Makefile.in:
	* win/makefile.vc:

	* libtommath/bn_mp_add_d.c:	Bug fix.  For mp_add_d(&a, d, &c),
	when &a has the value -d, then the value &c computed should be zero,
	but mp_add_d was producing an inconsistent zero value with a sign
	field of MP_NEG, something like a value of -0, which other routines
	in libtommath can't handle.

	* generic/tclExecute.c:	Dropped all creation of "bigOne" values
	and just use tommath routines that accept the value "1" directly.

2005-09-15  Miguel Sofer <[email protected]>

	* doc/ParseCmd.3: copy/paste fix [Bug 1292427]

2005-09-15  Don Porter  <[email protected]>

	* unix/configure:	autoconf-2.59

2005-09-15  Donal K. Fellows  <[email protected]>

	* unix/tcl.m4 (SC_TCL_EARLY_FLAGS): Added extra hack to allow Tcl
	to transparently open large files on RHEL 3. [Bug 1287638]

2005-09-14  Don Porter  <[email protected]>

	* generic/tclStringObj.c:	Bug fixes: ObjPrintfVA needed to
	support "*" fields and needed to interpret precision limits on
	%s conversions as a maximum number of bytes, not Tcl_UniChars, to
	take from the (char *) argument.

	* generic/tclBasic.c:	Updated several callers to use
	* generic/tclCkalloc.c: TclFormatToErrorInfo() and/or
	* generic/tclCmdAH.c:	TclObjPrintf().
	* generic/tclCmdIL.c:
	* generic/tclCmdMZ.c:
	* generic/tclDictObj.c:
	* generic/tclExecute.c:
	* generic/tclIORChan.c:
	* generic/tclIOUtil.c:
	* generic/tclNamesp.c:
	* generic/tclProc.c:

	* library/init.tcl:	Keep [unknown] in sync with errorInfo
	formatting rules.

2005-09-13  Don Porter  <[email protected]>

	* generic/tclBasic.c:	First caller of TclFormatToErrorInfo.

	* generic/tclInt.h:		Using stdarg.h conventions, add more
	* generic/tclStringObj.c:	fixed arguments to TclFormatObj() and
	TclObjPrintf().  Added new routine TclFormatToErrorInfo().

	* generic/tcl.h:	Explicitly standardized on the use of stdarg.h
	* generic/tclBasic.c:	conventions for functions with variable number
	* generic/tclInt.h:	of arguments.  Support for varargs.h has been
	* generic/tclPanic.c:	implicitly gone for some time now.  All
	* generic/tclResult.c:	TCL_VARARGS* macros purged from Tcl sources,
	* generic/tclStringObj.c:	leaving only some deprecated #define's
	* tools/genStubs.tcl:	in tcl.h for the sake of older extensions.

	* generic/tclDecls.h:	make genstubs

	* doc/AddErrInfo.3:	Replaced all documented requirement for use
	* doc/Eval.3:		of TCL_VARARGS_START() with requirement for
	* doc/Panic.3:		use of va_start().
	* doc/SetResult.3:
	* doc/StringObj.3:

2005-09-12  Don Porter  <[email protected]>

	[kennykb-numerics-branch]	Merge updates from HEAD.

	* generic/tclCmdAH.c:		Added support for the "ll" width	
	* generic/tclStringObj.c:	specifier to [format].

	* generic/tclStringObj.c (TclAppendFormattedObjs):	Bug fix:
	make sure %ld formats force the collection of a wide value, when
	the value could be a different long.

2005-09-09  Andreas Kupries <[email protected]>

	* generic/tclIORChan.c (RcDecodeEventMask): Added missing type
	  declaration for the parameter 'mask'. This fixes the [SF Tcl Bug
	  1286256]. The other warning can be removed only by removing the
	  panic/return code.

2005-09-09  Don Porter  <[email protected]>

	[kennykb-numerics-branch]	Merge updates from HEAD.

2005-09-09  Kevin Kenny  <[email protected]>

	* generic/tclStringObj.c:  Added two missing casts to silence
	messages from MSVC6.

2005-09-09  Don Porter  <[email protected]>

	* generic/tclInt.h:		New internal routine TclObjPrintf()
	* generic/tclStringObj.c:	is similar to TclFormatObj() but
	accepts arguments in non-Tcl_Obj format.

	* generic/tclInt.h:		New internal routines TclFormatObj()
	* generic/tclStringObj.c:	and TclAppendFormattedObjs() to offer
	sprintf()-like means to append to Tcl_Obj.  Work in progress toward
	[RFE 572392].

	* generic/tclCmdAH.c:	Compiler directive NEW_FORMAT when #define'd
	directs the [format] command to be implemented in terms of the new
	TclAppendFormattedObjs() routine.

2005-09-08  Donal K. Fellows  <[email protected]>

	TIP#254 IMPLEMENTATION

	* generic/tclLink.c (LinkTraceProc,ObjValue): Added many new of C var
	* generic/tcl.h:			      to link to, making it
	* doc/LinkVar.3:			      easier to seamlessly
	* generic/tclTest.c (TestlinkCmd):	      couple C code and Tcl
	* tests/link.test:			      scripts in an
	application. [Patch 1242844]

2005-09-07  Don Porter  <[email protected]>

	* generic/tclUtf.c (Tcl_UniCharToUtf):	Corrected handling of negative
	* tests/utf.test (utf-1.5):	Tcl_UniChar input value.  Incorrect
	handling was producing byte sequences outside of Tcl's legal internal
	encoding.  [Bug 1283976].

2005-09-06  Donal K. Fellows  <[email protected]>

	* generic/tclInt.h (List): Added flag to keep track of whether a list
	* generic/tclListObj.c:    with a string rep is provably canonical.
	* generic/tclUtil.c (Tcl_ConcatObj):  Do efficient concatenation and
	* generic/tclBasic.c (Tcl_EvalObjEx): evaluation when the list is
	canonical, and not just when the list is pure. This should make the
	"pure list" hacking introduced in 8.3 much more robust.

2005-09-05  Donal K. Fellows  <[email protected]>

	* generic/tclObj.c (pendingObjDataKey): Added missing 'static' to stop
	symbol from leaking outside the Tcl library. [Bug 1263012]

2005-09-02  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclScan.c:	Bug fix: The %o, %x, %i formats of [scan]
	must not accept any 0b or 0o prefixes.  [scan $s %o] must continue
	to work even with KILL_OCTAL enabled.

	* generic/tclInt.h:	Added TCL_PARSE_SCAN_PREFIXES to the flags
	* generic/tclStrToD.c:	accepted by TclParseNumber.

2005-09-01  Andreas Kupries <[email protected]>

	* unix/tclUnixSock.c (InitializeHostName): Synchronized use of
	  static modifier in declaration and definition of function.

	* unix/tclUnixChan.c (FileTruncateProc): Synchronized use of
	  static modifier in declaration and definition of function.

	* generic/tclResult.c (ReleaseKeys): Synchronized use of static
	  modifier in declaration and definition of function.

	* generic/tclListObj.c (NewListIntRep): Synchronized use of static
	  modifier in declaration and definition of function.

	* generic/tclEncoding.c (InitializeEncodingSearchPath):
	  Synchronized use of static modifier in declaration and
	  definition of function.

	* generic/tclEncoding.c (FillEncodingFileMap): Synchronized use of
	  static modifier in declaration and definition of function.

	* generic/tclIORChan.c (RcNewHandle): Synchronized use of static
	  modifier in declaration and definition of function.

2005-09-01  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclObj.c:	TclParseNumber calls meant to parse an
	integer value now pass the TCL_PARSE_INTEGER_ONLY flag.

	* generic/tclScan.c:	Extended [scan] to accept the %lld,
	%llo, %llx, and %lli formats.  Numeric scanning is now done
	via TclParseNumber calls.

	* generic/tclInt.h:	Extended TclParseNumber to accept new flag
	* generic/tclStrToD.c:	values TCL_PARSE_INTEGER_ONLY,
	TCL_PARSE_OCTAL_ONLY, and TCL_PARSE_HEXIDECIMAL_ONLY, to give caller
	more control over the parsing rules.

2005-08-31  Vince Darley <[email protected]>

	* doc/FileSystem.3:
	* unix/tclUnixFile.c:
	* windows/tclWinFile.c: clarify that Tcl_FSMatchInDirectory may
	be called with a NULL interpreter, and fix the code so this is
	allowed.  Tcl's core itself (tclEncoding.c:FillEncodingFileMap())
	calls this with a NULL interpreter.

2005-08-30  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclObj.c:	Extended bignum support to include bignums
	so large they will not pack into a Tcl_Obj.  When they outgrow Tcl's
	string rep length limits, a panic will result.

	* generic/tclTomMath.h:	Added mp_sqrt to routines from
	* unix/Makefile.in:	libtommath used by Tcl.
	* win/Makefile.in:
	* win/makefile.vc:

	* generic/tclBasic.c:	Extended sqrt(.) so that range covers
	the entire double range, accepting as many bignums in the domain
	as that will allow.

2005-08-29  Andreas Kupries <[email protected]>

	* library/tm.tcl (::tcl::tm::roots): Accepted Don Porter's patch
	  for [Tcl SF Bug 1189657]. Syncs the implementation to the
	  specification (TIP #189).

2005-08-29  Don Porter  <[email protected]>

	[kennykb-numerics-branch]	Merge updates from HEAD.

	* generic/tclBasic.c:	Restored round(.) to the Tcl 8.4 rules.

2005-08-29  Kevin Kenny  <[email protected]>

	* generic/tclBasic.c (ExprMathFunc): Restored "round away from
	* tests/expr.test (expr-46.*):       zero" behaviour to the
	                                     "round" function.  Added
	test cases for the behavior, including the awkward case of a
	number whose fractional part is 1/2-1/2ulp. [Bug 1275043]

2005-08-26  Andreas Kupries <[email protected]>

	* generic/tclIO.c: Moved Tcl_{Cut,Splice}Channel to
	  {Cut,Splice}Channel for internal use, and created new public
	  functions for Tcl_{Cut,Splice}Channel which walk the whole stack
	  of transformations and invoke the necessary thread actions.
	  Added code to Tcl_(Un)StackChannel to properly invoke the thread
	  actions when pushing and popping transformations on/from a
	  channel.

2005-08-26  Donal K. Fellows  <[email protected]>

	* generic/tclNamesp.c (NamespaceEnsembleCmd): Reset the result after
	creating an ensemble to clear any result object sharing (potentially
	caused by delete traces) so that we can safely return the name of the
	ensemble. Previously, this caused crashes in Snit's test suite.

2005-08-25  Donal K. Fellows  <[email protected]>

	* generic/tclListObj.c (UpdateStringOfList): Stop uncontrolled and
	unsafe crashes from happening when working with very large string
	representations. [Bug 1267380]

	* generic/tclExecute.c (TEBC:INST_DICT_LAPPEND): Stop dropping a
	duplicated object on the floor, which was a memory leak (and a wrong
	result too). Thanks to Andreas Kupries for reporting this.

2005-08-25  Don Porter  <[email protected]>

	[kennykb-numerics-branch] Merge updates from HEAD

	* generic/tclExecute.c: Bug fix.  INST_RSHIFT: shift of negative
	values produced incorrect results.

	* generic/tclExecute.c:	Bug fix.  INST_*SHIFT opcodes stack
	management. [expr 0<<6] should be 0, not 6.

	* generic/tclBasic.c:	Extended the domain of round(.) to all
	non-Inf, non-NaN doubles, using bignums for the result as needed.

	point numbers with the largest and smallest possible significands,
	and added test cases for them.

2005-08-24  Kevin Kenny  <[email protected]>

	* generic/tclExecute.c: Corrected some TRACE bugs that prevented
	compilation with --enable-symbols=all.
	* generic/tclStrToD.c: Revised commentary to prepare for a
	renaming of the file, removed some dead code, and fixed a bug
	where TclBignumToDouble failed on huge negative numbers.
	* tests/binary.test (binary-65.*): Added missing 'ieeeFloatingPoint' to
	large/small significand tests.
	* tests/expr.test (expr-45.*) Added missing braces around expressions.

	* generic/tclBasic.c:	Revised implementation of the ceil(.) and
	* generic/tclInt.h:	floor(.) math functions in light of the
	* generic/tclStrToD.c:	revised comparison operators, so that it
	is always true that ($x <= ceil($x)) and ($x >= floor($x)).  The	
	simple approach of "convert to double and call ceil() or floor()"
	could not guarantee that.

	* generic/tclExecute.c:	Bug fix: TclBignumToDouble return -Inf when
	appropriate.  Removed declarations of removed routines.

	* generic/tclExecute.c:	Revised the type promotion rules of the
	comparison operators so that they form proper equivalence classes
	over the set of numeric strings.

	* tests/expr.test (expr-40.1-42.1):
	* scan.test (scan-14.1,14.2):
	Modified Tcl_ParseNumber to accept an argument to force
	interpretation as decimal, and modified [scan] to use it.
	Corrected a bug where Not a Number with hexadecimal information
	bits returned consistently incorrect values. #ifdef-ed out
	some code that is needed only for IBM hexadecimal floating point.
	Fixed bugs in code to handle the corner cases of smallest and
	largest significands.  Added test cases to improve test coverage
	in generic/tclStrToD.c.	Added test cases for 0b notation (TIP
	#114).  Removed TclStrToD, and the static functions that it calls,
	which are now dead code (TclParseNumber	now does all input 
	floating-point conversions.)

	* generic/tclCmdAH.c:	or disables accepting of the NaN value at 
	* generic/tclExecute.c:	various points.
	* generic/tclLink.c:

	* generic/tclStrToD.c:	Bug fix.  Parsing of +/- Infinity was reversed.

	* generic/tclTestObj.c:	Disabled unused [testconvertobj] command.

	* generic/tclInt.h:		Moved TclParseInteger to tclUtil.c
	* generic/tclParseExpr.c:	and made it static.
	* generic/tclUtil.c:

	* generic/tclInt.decls:	Moved TclExprFloatError to tclBasic.c and

	* generic/tclExecute.c:

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

	* generic/tclExecute.c:	errno, IS_NAN, IS_INF, LLD no longer called in
	this file; dropped/disabled support for them.

	* generic/tclCompExpr.c:	errno no longer used in these files;
	* generic/tclParseExpr.c:	dropped support "hack" for it.

	* generic/tclStrToD.c:	Disabled out of date support "hack" for errno.

	* generic/tclBasic.c:	Eliminated VerifyExprObjType.  Initialize
	errno to zero in OldMathFuncProc.

2005-08-19  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclBasic.c:	Updated OldMathFuncProc and ExprAbsFunc to
	do less invasion into numeric Tcl_Obj internals.  Made ExprDoubleFunc,
	ExprIntFunc, ExprWideFunc, and ExprRoundFunc bignum-aware.  Revised
	ExprSrandFunc error message.

	* generic/tclProc.c:	Wrapped a few tclWideIntType uses in 
	* generic/tclCmdMZ.c:	#ifndef NO_WIDE_TYPE.

	* generic/tclInt.h:	#define'd NO_WIDE_TYPE.

	* generic/tclVar.c:	Replaced TclPtrIncrVar and TclPtrIncrWideVar
	* generic/tclInt.h:	with TclPtrIncrObjVar and replaced TclIncrVar2
	* generic/tclInt.decls:	and TclIncrWideVar2 with TclIncrObjVar2.  New

	* generic/tclDictObj.c:	DictIncrCmd rewrite to use TclIncrObj.

	* generic/tclInt.h:	TclIncrObj static -> internal
	* generic/tclExecute.c:

2005-08-17  George Peter Staplin <[email protected]>

	* generic/tclBasic.c: eliminate a namespace clash caused by
	BuiltinFuncTable not being static.

	* generic/tclObj.c: fix a namespace clash caused by a missing
	static for pendingObjData.

2005-08-17  Kevin Kenny  <[email protected]>

	* generic/tclEvent.c (Tcl_Finalize): Removed a copy-and-paste
	accident that caused a (mostly harmless) double finalize of the
	load and filesystem subsystems.
	* tests/clock.test: Eliminated the bad test clock-43.1, and split
	clock-50.1 into two tests, with a more permissive check on the
	error message for an out-of-range value.

2005-08-17  Kevin Kenny  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclBasic.c (Tcl_Expr{Long,Double}{,Obj}): Updated to
	* generic/tclTest.c:                                deal with
	* tests/expr-old.test:                              bignums (well, 
	* tests/expr.test:                                  mostly).
	Added a missing "errno=0;" in ExprUnaryFunc so that spurious
	error returns aren't detected. 
	Added test cases for Tcl_Expr* and Tcl_Expr*Obj because
	there was very poor test coverage in those areas.
	* generic/tclParseExpr.c: Reworked parsing of numbers to call
	TclParseNumber rather than trying to do things locally.
	* generic/tclStrToD.c: Corrected a comment. Changed so that
	*endPtrPtr does not include any trailing whitespace.
	
2005-08-17  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	New routine TclIncrObj to centralize the
	increment operation needed in many places.  Updated
	INST_DICT_INCR_IMM to make use of it.

2005-08-16  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Made bit shifting opcodes and INST_MOD
	bignum-aware.

	* tests/scan.test:	Making << bignum-aware means that repeated
	* tests/string.test:	left shifting cannot turn a positive into
	a negative.  Revised [int_range] and [largest_int] utility commands
	in the test suite that relied on that happening.  Without revision
	they became infinite loops.

	* generic/tclExecute.c:	Made binary bitwise opcodes bignum-aware.

	* generic/tclTomMath.h:	Added mp_or and mp_xor to routines from
	* unix/Makefile.in:	libtommath used by Tcl.
	* win/Makefile.in:
	* win/makefile.vc:

2005-08-15  Don Porter  <[email protected]>

	[kennykb-numerics-branch]	Updates from HEAD.
	* generic/tclExecute.c:	More revisions to IllegalExprOperandType.
	Merged INST_BITNOT with INST_UMINUS and make it bignum-aware
	according to the rule: ~a = -a - 1.  Disabled unused code and
	noted more TODOs.

	* generic/tclInt.decls: Disabled TclLooksLikeInt() and all callers.
	* generic/tclUtil.c:
	* generic/tclCompCmds.c:

	* generic/tclBasic.c:	Rewrite of VerifyExprObjType().

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

	* generic/tclExecute.c:	Updated execution of comparison bytecodes
	to be bignum-aware, routing string compares through INST_STR_CMP.

2005-08-14  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Updated execution of arithmetic bytecodes
	to be bignum-aware, and to allow calculations on NaN to produce
	a NaN result.  INST_UMINUS updated to call mp_neg.

	* generic/tclTomMath.h:	Added mp_and, mp_expt_d, and mp_neg to
	* unix/Makefile.in:	routines from libtommath used by Tcl.
	* win/Makefile.in:
	* win/makefile.vc:

2005-08-13  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclObj.c:	Extended Bignum auto-narrowing to auto-narrow
	to tclWideIntType when appropriate; this helps keep things working as
	the bytecode execution code is migrated to supporting bignums.

	* generic/tclExecute.c:	Major overhaul of IllegalExprOperandType.
	Changed several TclNewFooObj() calls to more logically appropriate
	ones.  Added several TODO comments marking opportunies for future
	work.  Made more use of the eePtr->constants.  Made INST_UMINUS
	bignum aware.

2005-08-12  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Simplify doCondJump.  Use eePtr->constants
	as result of INST_DICT_NEXT, INST_LAND, and INST_LOR.  Separate
	INST_LNOT from INST_UMINUS and simplify.

2004-08-12  Kevin Kenny  <[email protected]>

	* generic/tclClock.c (MktimeObjCmd):
	* library/clock.tcl (GetSystemTimeZone, LoadZoneinfoFile,
	ReadZoneinfoFile):
	* tests/clock.test (clock-50.1):
	Added functionality to read /etc/localtime if it exists, so that
	Tcl's time can track system time on Linux even if TZ is not set.
	Changed ::tcl::clock::Mktime to check for failure, and added a
	test case that mimics failure but is really success.
	
2005-08-11  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Rewrite of INST_LAND/INST_LOR to take
	advantage of loss of "pure double" issues.  Merged INST_UPLUS
	with INST_TRY_CVT_TO_NUMERIC and updated to use improved rules
	for impure "double"s as well.

	* generic/tclStrToD.c:	Restored conditional generation of
	tclWideIntType values by TclParseNumber so that Tcl's not
	completely broken while bignum calculation support is incomplete.
	The NO_WIDE_TYPE macro can be used to disable this.

	* generic/tclBasic.c (ExprAbsFunc):	First pass making [expr abs(.)]
	bignum-aware.

2004-08-11  Kevin Kenny  <[email protected]>

	* generic/tclEvent.c:          Eliminated the USE_THREAD_STORAGE
	* generic/tclInt.h:            option (which is on in every build
	* generic/tclThread.c:         generated by the standard configurator).
	* generic/tclThreadStorage.c:  Eliminated the code for thread
	* unix/configure:              specific data without USE_THREAD_STORAGE
	* unix/tcl.m4:                 and radically refactored the code
	* unix/tclConfig.h.in:         for USE_THREAD_STORAGE so that it
	* unix/tclUnixThrd.c:          has fewer dependencies on the order
	* win/configure:               of finalization.  (Also, made
	* win/Makefile.in:             'make distclean' on Windows clean
	* win/rules.vc:                just a little bit cleaner.)
	* win/tcl.m4:
	* win/tclWinThrd.c:
	
2005-08-10  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclTomMath.h:	Added mp_shrink, mp_to_unsigned_bin,
	* unix/Makefile.in:	mp_to_unsigned_bin_n, and mp_unsigned_bin_size
	* win/Makefile.in:	to routines from libtommath used by Tcl.
	* win/makefile.vc:

	* generic/tommath.h:	make gentommath_h

	* generic/tclObj.c:	Substantial rewrite to make all number
	parsing flow through TclParseNumber().  Also established the
	NO_WIDE_TYPE and BIGNUM_AUTO_NARROW #ifdef's to help track the
	assumptions of different portions of the code.

	* generic/tclInt.h:	Added NO_WIDE_TYPE #ifdefs

2005-08-10  Kevin Kenny  <[email protected]>

	* generic/tclEvent.c (Tcl_Finalize): Pushed Tcl_FinalizeLoad and
	Tcl_ResetFilesystem down after Tcl_FinalizeThreadAlloc because
	we can't unload DLL's until after their TSD keys are finalized.
	(Note that we'll still see aborts if an unloaded DLL has TSD -
	that still needs to be fixed.

	* tests/compExpr-old.test (compExpr-3.8): Made tests conditional on
	* tests/expr.test (expr-3.8):             'unix' because they get
	                                          stack overflows on Win32
	                                          threaded builds,

2005-08-09  Vince Darley  <[email protected]>

	* generic/tclPathObj.c: fix to [file rootname] bug in optimized
	code path reported on comp.lang.tcl.

2005-08-08  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclObj.c:	Replaced some goto's with loops and started
	use of BIGNUM_AUTO_NARROW and NO_WIDE_TYPE.

2005-08-06  Donal K. Fellows  <[email protected]>

	* generic/tclThreadStorage.c: Stop exposing the guts of the thread
	storage system through the internal stubs table. Client code
	should always use the standard API.

2005-08-05  Don Porter  <[email protected]>

	[kennykb-numerics-branch]
	* generic/tclObj.c:	Rewrote Tcl_GetDoubleFromObj().

2005-08-05  Donal K. Fellows  <[email protected]>

	* unix/tclUnixInit.c (localeTable): Solaris uses a non-standard
	name for the cp1251 charset. Thanks to Victor Wagner for reporting
	this. [Bug 1252475]

2005-08-05  Kevin Kenny  <[email protected]ourceforge.net>

	* win/makefile.vc: Removed unused file ldAout.tcl.

	* tests/binary.test: Cleaned up testing for scanning of NaN.
			     [Bug #1246264]

	* generic/tclBasic.c (ExprAbsFunc): Added code to handle the
	* tests/expr.test (expr-38.1):      corner case of applying
	'abs' to the smallest 32-bit integer. [Bug #1241572]

2005-08-04  Andreas Kupries <[email protected]>

	* generic/tclIO.c (CloseChannel): Fixed comment nit, added
	  apparently missing word to complete a sentence.

	* generic/tclObj.c (Tcl_DbDecrRefCount): Fixed whitespace nit in
	  panic message.

2005-08-04  Don Porter  <[email protected]>

	[kennykb-numerics-branch] Updated from HEAD

	* generic/tclObj.c:	Rewrote Tcl_GetBooleanFromObj() and supporting
	routines to make use of TclParseNumber.  This reduces the potential
	number of times a string value must be scanned.

	* generic/tclObj.c:	Simplified routines that manage the typeTable.
	Deleted the UpdateStringOfBoolean() routine, that can never be called.

2005-08-03  Don Porter  <[email protected]>

	* generic/tclCompExpr.c:	Untangled some dependencies in the

	* win/README: Update link to msys_mingw8.zip.

2005-07-28  Don Porter	<[email protected]>

	* tests/compExpr-old.test:	Still more conversion of "nonPortable"
	* tests/error.test:		tests into tests with constraints that
	* tests/expr-old.test:		describe the limits of their
	* tests/expr.test:		portability.  Also more consolidation
	* tests/fileName.test:		of constraint synonyms.
	* tests/format.test:		wideis64bit, 64bitInts => wideIs64bit
	* tests/get.test:		wideIntegerUnparsed => wideIs32bit
	* tests/load.test:		wideIntExpressions => wideBiggerThanInt
	* tests/obj.test:
	* tests/parseExpr.test:		Dropped "roundOffBug" constraint that
	* tests/string.test:		protected from buggy sprintf.

2005-07-28  Donal K. Fellows  <[email protected]>

	* generic/tclPipe.c (TclCreatePipeline): Arrange for POSIX systems to
	* unix/tclUnixPipe.c (TclpOpenFile):	 use the O_APPEND flag for
	* tests/exec.test (exec-19.1):		 files opened in a pipeline
	like ">>this".	Note that Windows cannot support such access; there is
	no equivalent flag on the handle that can be set at the kernel-call
	level. The test is unix-specific in every way. [Bug 1245953]

2005-07-27  Don Porter	<[email protected]>

	* generic/tclUtil.c:	Converted the $::tcl_precision value to be
	kept per-thread to prevent different threads from stomping on each
	others' formatting prescriptions.

	***POTENTIAL INCOMPATIBILITY*** Multi-threaded programs that set
	the value of ::tcl_precision will now have to set it in each thread.

	* tests/expr.test:	Consolidated equivalent constraints into
	* tests/fileName.test:	single definitions and (more precise) names:
	* tests/get.test:	longis32bit, 32bit, !intsAre64bit => longIs32bit
	* tests/listObj.test:	empty => emptyTest; winOnly => win
	* tests/obj.test:	intsAre64bit => longIs64bit
	Also updated some "nonPortable" tests to use constraints that mark
	precisely what about them isn't portable, so the tests can run where
	they work.

	* library/init.tcl ([unknown]):	Corrected return code handling
	in the portions of [unknown] that expand incomplete commands
	during interactive operations.	[Bug 1214462].

2005-07-26  Mo DeJong  <[email protected]>

	* unix/configure: Regen.
	* unix/configure.in: Check for a $prefix/share
	directory and add it the the package if found.
	This will check for Tcl packages in /usr/local/share
	when Tcl is configured with the default dist install.
	[patch 1231015]

2005-07-26  Don Porter	<[email protected]>

	* generic/tclBasic.c (Tcl_CallWhenDeleted):	Converted to use
	per-thread counter, rather than a process global one that required
	mutex protection.  [RFE 1077194]

	* generic/tclNamesp.c (TclTeardownNamespace):	Re-ordering so that
	* tests/trace.test (trace-34.4):	command delete traces fire
	while the command still exists.	 [Bug 1047286]

2005-07-24  Mo DeJong  <[email protected]>

	* unix/configure: Regen.
	* unix/tcl.m4 (SC_PROG_TCLSH, SC_BUILD_TCLSH):
	* win/configure: Regen.
	* win/tcl.m4 (SC_PROG_TCLSH, SC_BUILD_TCLSH):
	Split confused search for tclsh on PATH and
	build and install locations into two macros.
	SC_PROG_TCLSH searches just the PATH.
	SC_BUILD_TCLSH determines the name of the tclsh
	executable in the Tcl build directory.

	* generic/tclExecute.c (INST_DICT_*): stop 2 compiler
	warnings for uninitialised variables.

2005-07-23  Donal K. Fellows  <[email protected]>

	* generic/tclExecute.c (TEBC:INST_DICT_INCR_IMM): Fix the
	incrementor to work correctly with wide values.

2005-07-21  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c (TclCompileDictCmd): First run at a compiler
	* generic/tclExecute.c (TclExecuteByteCode): for dictionaries.
	Also added an instruction to support 'finally'-like clauses, exposed
	more of the dict guts to the rest of the core, and defined a few
	tests to exercise more obscure parts of the compiler's operation that
	were bugs during development.

2005-07-21  Kevin B. Kenny  <[email protected]>

	* library/ldAout.tcl (***REMOVED***):	Removed support for ancient
	* unix/configure:			BSD's, IRIX 4, RISCos and
	* unix/Makefile.in:			Ultrix.	 Removed two files
	* unix/tcl.m4:				whose code is used only on
	* unix/tclLoadAout.c (***REMOVED***):	those antique platforms.

	***POTENTIAL INCOMPATIBILITY*** if anyone actually uses those
	platforms; it is to be noted though, that an error in the
	installer has actually not caused a necessary file to be installed
	on those platforms in several releases, and nobody's complained.

2005-07-15  Kevin B. Kenny  <[email protected]>

	* generic/tclClock.c (TclClockLocaltimeObjCmd,ThreadSafeLocalTime):
	* library/clock.tcl (GuessWindowsTimeZone, ClearCaches):
	* tests/clock.test (clock-49.1, clock-49.2):
	Handle correctly the case where localtime() returns NULL to
	report a conversion error.  Also handle the case where the Windows
	registry contains timezone values that can be mapped to a tzdata
	file name but the corresponding file does not exist or is
	corrupted, by falling back on a Posix timezone string instead;
	this last case will avoid calls to localtime() in starpacks on
	Windows. [Bug 1237907]

2005-07-14  Donal K. Fellows  <[email protected]>

	* generic/tclCompile.c: Update to follow style guidelines.
	(TclPrintInstruction): Reorganize to do better printing out of
	bytecode with far fewer "special hacks" for particular opcodes.
	* generic/tclCompile.h: Requires two new opcode types.

2005-07-13  Don Porter	<[email protected]>

	* unix/tclUnixSock.c:	Use a ProcessGlobalValue to store the
	* win/tclWinSock.c:	value returned by Tcl_GetHostName()
	([info hostname]).  Also re-order initialization of the value
	on Windows to favor GetComputerName() over gethostname() as
	a source of the information.

2005-07-12  Kevin Kenny  <[email protected]>

	[kennykb-numerics-branch] Updated from HEAD

	* generic/tclCmdMZ.c (Tcl_StringObjCmd):
	* generic/tclInt.h:
	* generic/tclObj.c (Tcl_GetDoubleFromObj, SetDoubleFromAny,
	                    Tcl_GetIntFromObj, SetIntOrWideFromAny):
	* generic/tclStrToD.c (TclParseNumber, etc.):
	* tclTomMathInterface.c (TclBNInitBignumFromWideUInt):
	* tests/obj.test (obj-1.1, obj-2.2, obj-3.1, obj-3.2):
	
	Initial attempt at an implementation of TIP #249, comprising
	a unified parser and modifications to the Tcl_Get*FromObj
	routines to use it.  Further integration of the parser is
	necessary and planned.
	
2005-07-12  Donal K. Fellows  <[email protected]>

	* doc/lsearch.n: Clarify documentation of -exact option; wording was
	open to misinterpretation by non-English speakers.

2005-07-11  Donal K. Fellows  <[email protected]>

	* generic/tclExecute.c: General style cleanup.

2005-07-08  Mo DeJong  <[email protected]>

	* generic/tclExecute.c (TclExecuteByteCode): Reimplement long and wide
	type integer division and modulus operations so that the smallest and
	largest integer values are handled properly.  The divide operation is
	more efficient since it no longer does a modulus or negation and only
	checks for a remainder when the quotient will be a negative number.
	The modulus operation is now a bit more complex because of a number of
	special cases dealing with the smallest and largest integers.
	* tests/expr.test: Add test cases for division and modulus operations
	on the smallest and largest integer values for 32 and 64 bit types.
	[Patch 1230205]

2005-07-06  Don Porter	<[email protected]>

	* generic/tclLink.c:	Simplified LinkTraceProc [Bug 1208108].

2005-07-05  Don Porter	<[email protected]>

	* unix/Makefile.in:	Purged use of TCLTESTARGS [RFE 1161550].

	* generic/tclUtil.c:	Converted TclFormatInt() into a macro.
	* generic/tclInt.decls:	[RFE 1194015]
	* generic/tclInt.h:

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

	* generic/tclNamesp.c:	Allow for [namespace import] of a command
	* tests/namespace.test:	over a previous [namespace import] of itself
	without throwing an error.  [RFE 1230597]

2005-07-04  Donal K. Fellows  <[email protected]>

	* generic/tclDictObj.c (DictForCmd, DictFilterCmd): Interlocking of
	dictionary internal representations is now done in the core of the
	dict iterator. Purge the last attempts at doing it at a higher level
	as they didn't work and were no longer needed.

2005-07-01  Zoran Vasiljevic <[email protected]>

	* unix/tclUnixNotfy.c: protect against spurious wake-ups while
	waiting on the condition variable when tearing down the notifier
	thread [Bug# 1222872].

2005-06-28  Mo DeJong  <[email protected]>

	* generic/tclExecute.c (TclExecuteByteCode): When parsing an integer
	operand for a unary minus expression operator, check for a wide
	integer that is actually LONG_MIN. If found, convert it back to a long
	int type.
	* tests/expr.test: Add constraint for 32bit long int type and 64bit
	wide int type. Add tests that parse the smallest/largest long int and
	wide int values.

2004-06-24  Kevin Kenny	 <[email protected]>

	* generic/tclEvent.c (Tcl_Finalize):
	* generic/tclInt.h:
	* generic/tclPreserve.c (TclFinalizePreserve): Changed the
	finalization logic so that Tcl_Preserve finalizes after exit handlers
	run; a lot of code called from Tk's exit handlers presumes that
	Tcl_Preserve will still work even from an exit handler.

2005-06-24  Don Porter	<[email protected]>

	* library/auto.tcl:	Make file safe to re-[source] without
	destroying registered auto_mkindex_parser hooks.

2005-06-23  Kevin Kenny	 <[email protected]>

	* win/tclWinChan.c: More rewriting of __asm__ blocks that implement
	* win/tclWinFCmd.c: SEH in GCC, because mingw's gcc 3.4.2 is not as
	forgiving of violations committed by the old code and caused panics.
	[Bug #1225957]

2005-06-23  Daniel Steffen  <[email protected]>

	* tools/tcltk-man2html.tcl: fixed useversion glob pattern to accept
	multi-digit patchlevels.

2005-06-22  Don Porter	<[email protected]>

	* win/tclWinFile.c: Potential buffer overflow.	[Bug 1225571]
	Thanks to Pat Thoyts for discovery and fix.

2005-06-22  Kevin Kenny <[email protected]>

	* generic/tclInt.h:			    Changed the finalization
	* generic/tclEvent.c (Tcl_Finalize):	    logic to defer the
	* generic/tclIO.c (TclFinalizeIOSubsystem): shutdown of the pipe
	* unix/tclUnixPipe.c (TclFinalizePipes):    management until after
	* win/tclWinPipe.c (TclFinalizePipes):	    all channels have been
	closed, in order to avoid a situation where the Windows PipeCloseProc2
	would re-establish the exit handler after exit handlers had already
	run, corrupting the heap. [Bug #1225727]
	Also corrected a potential read of uninitialized memory in
	PipeClose2Proc [Bug #1225044]

2005-06-21  Andreas Kupries <[email protected]>

	* generic/tclInt.h: Followup to change made on 2005-06-18 by Daniel
	Steffen. There are compilers (*) who error out on the redefinition of
	WORDS_BIGENDIAN. We have to undef the previous definition (on the
	command line) first to make this acceptable. (*): AIX native.

2005-06-21  Kevin B. Kenny  <[email protected]>

	* generic/tclFileName.c: Changed [file split] and [file join] to treat
	Windows drive letters similarly to ~ syntax and make sure that they
	appear with "./" in front when they are in intermediate components of
	the path. [Bug 1194458]
	* tests/fileName.test: Added test for the above bug.

2005-06-21  Don Porter	<[email protected]>

	* generic/tclBasic.c:	Added missing walk of the list of active traces
	* generic/tclTrace.c:	to cleanup references to traces being deleted.
	* generic/tclInt.h:	[Bug 1201035] Made the walk of the active trace
	* tests/trace.test (trace-34.*): list aware of the direction of trace
	scanning, so the proper correction can be made. [Bug 1224585]

2005-06-21  Donal K. Fellows  <[email protected]>

	* unix/tcl.m4 (SC_ENABLE_SYMBOLS): Only enable the 'compile' special
	debugging feature when requested in configure.in; removes irrelevant
	junk from the configure files of extensions that use Tcl's tcl.m4.

2005-06-20  Donal K. Fellows  <[email protected]>

	* generic/tclCompile.h (INST_PUSH_RETURN_OPTIONS): New opcode to allow
	* generic/tclCompCmds.c (TclCompileCatchCmd):	   compilation of TIP90
	* generic/tclCompile.c:				   catch [Bug 1219112]
	* generic/tclExecute.c (TclExecuteByteCode):

	* generic/tclCompCmds.c (TclCompileSwitchCmd): Ensure we spill to the
	command form in all cases where it generates an error.

2005-06-20  Mo DeJong  <[email protected]>

	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Generate an error if a mode
	argument like -exact is passed more than once to the switch command.
	The previous implementation silently accepted invalid switch
	invocations like [switch -exact -glob $str ...].
	* tests/for.test: Check some error cases when invoking continue and
	break inside a for loop next script.
	* tests/switch.test: Add checks for shortened version of a mode
	argument like -exact. Add test for more than one mode argument. Add
	test for odd case of passing a variable as a body script.

2005-06-18  Daniel Steffen  <[email protected]>

	* generic/tclInt.h: ensure WORDS_BIGENDIAN is defined correctly with
	fat compiles on Darwin (i.e. ppc and i386 at the same time), the
	configure AC_C_BIGENDIAN check is not sufficient in this case because
	a single run of the compiler builds for two architectures with
	different endianness.

	* unix/tcl.m4 (Darwin): add -headerpad_max_install_names to LDFLAGS to
	ensure we can always relocate binaries with install_name_tool.

	* unix/configure: autoconf-2.59

2005-06-18  Donal K. Fellows  <[email protected]>

	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Fix for [Bug 1154163]; only
	* tests/format.test: insert 'l' modifier when it is needed.

2005-06-17  Donal K. Fellows  <[email protected]>

	* generic/tclTimer.c (AfterDelay): Split out the code to manage
	synchronous-delay [after] commands.
	* tests/interp.test (interp-34.10): Time limits and synch-delay
	[after] did not mix well... [Bug 1221395]

2005-06-14  Donal K. Fellows  <[email protected]>

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken): Only delete a
	* tests/namespace.test (namespace-49.2): command from the hashtable on
	reentrant processing if it has not been already deleted; at least
	three deletes of the same command are possible. [Bug 1220058]
	* generic/tclTrace.c (TraceCommandProc): Remove bogus error message
	creation when traces trigger in situations where the command has
	already been deleted.

2005-06-13  Vince Darley  <[email protected]>

	* generic/tclFCmd.c: correct fix to file mkdir 2005-06-09, [Bug 1219176]

2005-06-12  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c: Factor out some common idioms into named
	forms for greater clarity.

2005-06-10  Donal K. Fellows  <[email protected]>

	* doc/chan.n: Fold in the descriptive parts of the documentation
	for all the commands that [chan] builds on top of.

2005-06-09  Vince Darley  <[email protected]>

	* generic/tclFCmd.c: fix to race condition in file mkdir [Bug 1217375]
	* doc/glob.n: improve glob documentation [Bug 1190891]

2005-06-09  Donal K. Fellows  <[email protected]>

	* doc/expr.n, doc/mathfunc.n: Fix minor typos [Bug 1211078] and
	add mention of distinctly-relevant [namespace path] subcommand.

2005-06-07  Don Porter	<[email protected]>

	* generic/tclInt.h:		Reduced the Tcl_ObjTypes "index",
	* generic/tclIndexObj.c:	"ensembleCmd", "localVarName", and
	* generic/tclNamesp.c:		"levelReference" to file static scope.
	* generic/tclProc.c:
	* generic/tclVar.c:

	* generic/tclObj.c:	Restored registration of the "procbody"
	Tcl_ObjType, as required by the tclcompiler application.

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

2005-06-07  Donal K. Fellows  <[email protected]>

	* generic/tclIO.c (Tcl_ChannelTruncateProc): Stop proliferation of
	* generic/tcl.h:			     channel type versions
	* doc/CrtChannel.3:			     following advice from AKu

	Bump patchlevel to a4 to distinguish from a3 release.

	* generic/tclInt.h (INTERP_TRACE_IN_PROGRESS): Add flag so the error
	* generic/tclIndexObj.c (Tcl_WrongNumArgs):    messages from ensembles
	* generic/tclIOCmd.c (Tcl_ReadObjCmd):	       can be correct.

	TIP#208 IMPLEMENTATION

	* library/init.tcl: Create the chan ensemble.
	* tests/chan.test: Rudimentary test suite.
	* doc/chan.n: General documentation.

	TRUNCATION API (part of TIP#208)
	* generic/tcl.h, generic/tcl.decls: Declaration of the API.
	* doc/CrtChannel.3, doc/OpenFileChnl.3: Documentation of the API.
	* generic/tclBasic.c (Tcl_CreateInterp): Create the mapping into Tcl.
	* generic/tclIOCmd.c (TclChanTruncateObjCmd): Implementation of
	Tcl-level truncation API.
	* generic/tclIO.c (Tcl_TruncateChannel): Generic C-level
	truncation API implementation.
	* unix/tclUnixChan.c (FileTruncateProc): Basic implementation of
	truncating driver.

	* win/tclWinChan.c (FileTruncateProc): Added implementation of
	file truncation for Windows.
	* tests/chan.test (chan-15.2): Added real test of truncation.

2005-06-06  Kevin B. Kenny  <[email protected]>

	* win/tclWin32Dll.c: Corrected another buglet in the assembly code for
	stack probing on Win32/gcc. [Bug #1213678]
	* generic/tclObj,c: Added missing 'static' on definition of
	UpdateStringOfBignum, and removed a 'switch' on a 'long long' operand
	(which HP-UX native 'cc' seems unable to handle). [Bug #1215775]

2005-06-04  Jeff Hobbs	<[email protected]>

	*** 8.5a3 TAGGED FOR RELEASE ***

	* unix/Makefile.in (dist): add libtommath

2005-06-03  Donal K. Fellows  <[email protected]>

2005-06-02  Jeff Hobbs	<[email protected]>

	* unix/Makefile.in (html): add BUILD_HTML_FLAGS optional var
	* tools/tcltk-man2html.tcl: add a --useversion to prevent
	confusion when multiple Tcl source dirs exist.

2005-06-01  Don Porter	<[email protected]>

	* generic/tclBasic.c:	For compatibility with earlier Tcl releases,
	* generic/tclResult.c:	when a command procedure simply does a
	* generic/tclTest.c:	"return TCL_RETURN;" we must interpret that
	* tests/result.test:	the same as
	"return Tcl_SetReturnOptions(interp, Tcl_NewObj());"  [Bug 1209759].

2005-06-01  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c (TclCompileSwitchCmd): Allow compilation
	of -nocase -glob [switch]es (only one we know how to compile).

	TIP#241 IMPLEMENTATION from Joe Mistachkin

	* generic/tclCmdIL.c (Tcl_LsearchObjCmd, Tcl_LsortObjCmd):
	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Implementation of -nocase
	option for [lsearch], [lsort] and [switch] commands.
	* win/tclWinPort.h: Win uses nonstandard function names...
	* tests/cmdIL.test, tests/lsearch.test, tests/switch.test: Tests
	* doc/lsearch.n, doc/lsort.n, doc/switch.n: Docs

	* generic/tclCompCmds.c (TclCompileLindexCmd): Compile the most
	common case of [lindex] more efficiently.

	* unix/tclUnixNotfy.c (Tcl_FinalizeNotifier): Pass the correct
	number of arguments to Tcl_JoinThread.

2005-05-31  Donal K. Fellows  <[email protected]>

	* unix/configure.in, unix/tcl.m4: Standardize generation of help
	messages to always use AC_HELP_STRING and always (except for
	--with-tcl and --with-tk, where the default is complex) say what
	the default is.

2005-05-31  Zoran Vasiljevic <[email protected]>

	* unix/tclUnixNotfy.c: the notifier thread is now created as
	joinable thread and it is properly joined in Tcl_FinalizeNotifier.
	This is an attempt to fix the Tcl Bug #1082283.

2005-05-30  Zoran Vasiljevic <[email protected]>

	* win/tclWinThrd.c: Fixed Tcl Bug #1204064.

2005-05-30  Donal K. Fellows  <[email protected]>

	TIP #229 IMPLEMENTATION

	* generic/tclNamesp.c (Tcl_FindCommand, TclResetShadowedCmdRefs)
	(NamespacePathCmd, SetNsPath, UnlinkNsPath, TclInvalidateNsPath):
	Implementation of the [namespace path] command and the command
	name resolution engine.
	* doc/info.n, doc/namespace.n: Doc updates.
	* tests/namespace.test (namespace-51.*): Test updates.

2005-05-26  Daniel Steffen  <[email protected]>

	* macosx/Makefile: moved & corrected EMBEDDED_BUILD check.

	* unix/configure.in: corrected framework finalization to softlink
	stub library to Versions/8.x subdir instead of Versions/Current.
	* unix/configure: autoconf-2.59

2005-05-25  Jeff Hobbs	<[email protected]>

	* generic/tclCmdMZ.c (Tcl_TimeObjCmd): add necessary cast

2005-05-25  Don Porter	<[email protected]>

	TIP#182 IMPLEMENTATION	[Patch 1165062]

	* doc/mathfunc.n:	New built-in math function bool().
	* generic/tclBasic.c:
	* tests/expr.test:
	* tests/info.test:

2005-05-24  Don Porter	<[email protected]>

	* library/init.tcl:	Updated [unknown] to be sure the [return]
	* tests/init.test:	options from an auto-loaded command are
	seen correctly by the caller.

2005-05-24  Daniel Steffen  <[email protected]>

	* tests/env.test: added DYLD_FRAMEWORK_PATH to the list of env vars
	that need to be handled specially.

	* macosx/Makefile:
	* macosx/README:
	* macosx/Tcl-Info.plist.in (new file):
	* unix/Makefile.in:
	* unix/configure.in:
	* unix/tcl.m4:
	* unix/tclUnixInit.c: moved all Darwin framework build support from
	macosx/Makefile into the standard unix configure/make buildsystem, the
	macosx/Makefile is no longer required to build Tcl.framework (but its
	functionality is still available for backwards compatibility).
	* unix/configure: autoconf-2.59

	* generic/tclIOUtil.c (TclLoadFile):
	* generic/tclInt.h:
	* unix/tcl.m4:
	* unix/tclLoadDyld.c: added support for [load]ing .bundle binaries in
	addition to .dylib's: .bundle's can be [unload]ed (unlike .dylib's),
	and can be [load]ed from memory, e.g. directly from VFS without
	needing to be written out to a temporary location first. [Bug 1202209]
	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

	* generic/tclCmdMZ.c (Tcl_TimeObjCmd): change [time] called with a
	count > 1 to return a string with a float value instead of a rounded
	off integer. [Bug 1202178]

	* doc/expr.n:
	* doc/string.n: fixed roff syntax complaints from 'make html'.

2005-05-20  Don Porter	<[email protected]>

	* generic/tclParseExpr.c:	Corrected parser to recognize all
	boolean literals accepted by Tcl_GetBoolean, including prefixes
	like "y" and "f", and to allow "eq" and "ne" as function names
	in the proper context.	[Bug 1201589].

2005-05-19  Donal K. Fellows  <[email protected]>

	* generic/tclBasic.c (TclEvalObjvInternal): Rewrite for greater
	clarity; although 'goto' is Bad, the contortions you have to go
	through to avoid it can be worse...

2005-05-19  Daniel Steffen  <[email protected]>

	* macosx/tclMacOSXNotify.c (Tcl_InitNotifier): fixed crashing
	CFRelease of runLoopSource in Tcl_InitNotifier (reported by Zoran):
	CFRunLoopAddSource doesn't CFRetain, so can only CFRelease the
	runLoopSource in Tcl_FinalizeNotifier.

2005-05-18  Don Porter	<[email protected]>

	* generic/tclBasic.c (Tcl_ExprBoolean):	Rewrite as wrapper around
	Tcl_ExprBooleanObj.

	* generic/tclCmdMZ.c ([string is boolean/true/false]):	Rewrite
	dropping string-based Tcl_GetBoolean call, so that internal reps
	are kept for subsequent quick boolean operations.

	* generic/tclExecute.c:	Dropped most special handling of the
	"boolean" Tcl_ObjType, since that type should now be rarely
	encountered.

	* doc/BoolObj.3:	Rewrite of documentation dropping many details
	about the internals of Tcl_Objs.  Shorter documentation focuses on
	the function and use of the routines.

	* generic/tclInt.h:	Revision to the "boolean" Tcl_ObjType, so
	* generic/tclObj.c:	that only string values like "yes" and "false"
	* tests/obj.test:	are kept as the "boolean" Tcl_ObjType.	The
	string values "0" and "1" are kept as "int" Tcl_ObjType, which also
	produce quick calls to Tcl_GetBooleanFromObj().	 Since this internal
	change means a Tcl_ConvertToType to a "boolean" Tcl_ObjType might
	not produce a Tcl_Obj of type "boolean", the registration of the
	"boolean" type is also removed.
	***POTENTIAL INCOMPATIBILITY***
	For callers of Tcl_GetObjType on the type name "boolean".

2005-05-17  Don Porter	<[email protected]>

	* generic/tclObj.c (TclInitObjSubsystem):	Removed the
	* tests/listObj.test:	registration of the Tcl_ObjType's "list",
	* tests/obj.test:	"procbody", "index", "ensembleCommand",
	"localVarName", and "levelReference".  The only reason to register
	a Tcl_ObjType is to have it returned by Tcl_GetObjType, and the
	only reason for that is to retrieve a (Tcl_ObjType *) to pass to
	Tcl_ConvertToType().  None of the types above can support a
	Tcl_ConvertToType() call; they panic.  Better not to offer something
	than to lead users into a panic.
	***POTENTIAL INCOMPATIBILITY***
	For callers of Tcl_GetObjType on the type names listed above.

2005-05-15  Kevin Kenny	 <[email protected]>

	* win/tclWin32Dll.c: conditioned definition of
	EXCEPTION_REGISTRATION structures on HAVE_NO_SEH, to fix a bug in
	buildability on MSVC.

2005-05-14  Daniel Steffen  <[email protected]>

	* generic/tclInt.decls:
	* generic/tclTest.c:
	* generic/tclUtil.c:
	* win/tclWin32Dll.c: fixed link error due to direct access by
	tclTest.c to the MODULE_SCOPE tclPlatform global: renamed existing
	TclWinGetPlatform() accessor to TclGetPlatform() and moved it to
	generic code so that it can be used by on all platforms where
	MODULE_SCOPE is enforced.

	* macosx/tclMacOSXBundle.c:
	* unix/tclUnixInit.c:
	* unix/tcl.m4 (Darwin): made use of CoreFoundation API configurable
	and added test of CoreFoundation availablility to allow building on
	ppc64, replaced HAVE_CFBUNDLE by HAVE_COREFOUNDATION; test for
	availability of Tiger or later OSSpinLockLock API.

	* unix/tclUnixNotfy.c:
	* unix/Makefile.in:
	* macosx/tclMacOSXNotify.c (new file): when CoreFoundation is
	available, use new CFRunLoop based notifier: allows easy integration
	with other event loops on Mac OS X, in particular the TkAqua Carbon
	event loop is now integrated via a standard tcl event source (instead
	of TkAqua upon loading having to finalize the exsting notifier and
	replace it with its custom version). [Patch 1202052]

	* tests/unixNotfy.test: don't run unthreaded tests on Darwin
	since notifier may be using threads even in unthreaded core.

	* unix/tclUnixPort.h:
	* unix/tcl.m4 (Darwin): test for thread-unsafe realpath durning
	configure, as Darwin 7 and later realpath is threadsafe.

	* macosx/Makefile: enable configure caching.

	* unix/configure.in: wrap tclConfig.h header in #ifndef _TCLCONFIG so
	that it can be included more than once without warnings from gcc4.0
	(as happens e.g. when including both tclInt.h and tclPort.h)

	* macosx/tclMacOSXBundle.c:
	* unix/tclUnixChan.c:
	* unix/tclLoadDyld.c:

	* win/tclWin32Dll.c: Further rework of the SEH logic.  All
			     EXCEPTION_REGISTRATION records are now
			     in the activation record rather than pushed
			     on the stack.

2005-05-13  Don Porter	<[email protected]>

	* generic/tclBasic.c:	Dropped the TCL_NO_MATH configuration.
	* generic/tclBinary.c:	It's believed this has not been working
	* generic/tclExecute.c: in a long time.	 Tcl needs math.h.
	* unix/Makefile.in:	[RFE 1200680].

2005-05-12  Kevin Kenny	 <[email protected]>

	* doc/mathfunc.n: Changed NAME line to match the name of the page.

2005-05-11  Kevin Kenny  <[email protected]>

	* generic/tclStrToD.c (TclStrToD, RefineResult, ParseNaN):
	Changed the code to cast 'char' to UCHAR explicitly when
	using ctype macros, to silence complaints from the Solaris
	compiler.

2005-05-10  Jeff Hobbs	<[email protected]>

	* unix/tclUnixFCmd.c: add lint attr to enum to satisfy strictly
	compliant compilers that don't like trailing ,s.

	* tests/string.test: string-10.[21-30]

	resulted in reads of uninitialized memory when using 'd',
	'q', or 'Q' format.
	* generic/tclStrToD.c (ParseNaN, TclFormatNaN): Added code to
	handle the peculiarities of HP's PA_RISC, which uses a different
	'quiet' bit in NaN from everyone else.

		with -fomit-frame-pointers.

2005-05-08  Kevin B. Kenny  <[email protected]>

	[kennykb-numerics-branch]
	* generic/tclStrToD.c: Made code more portable by finding a
			       workaround for MSVC's 'volatile' issue that
			       does not require conditional compilation.
	* win/tclWin32Dll.c (TclWinCPUID): Removed structured event
					   handling from the GCC code
					   since (a) bad code is generated
					   by the instruction scheduling
					   with -O2, and (b) it's not
					   needed on any reasonably modern
					   CPU.

	* generic/tclInt.h:    static constants into a procedure called
	* generic/tclStrToD.c: from TclInitSubsystems to avoid double
			       checked locking protocol. Cleaned up
			       an issue where MSVC ignored the 'volatile'
			       specifier, causing incorrect comparison
			       of an underflowed number against zero.

2005-05-06  Jeff Hobbs	<[email protected]>

	can use the TCL_ERROR return code to signal any failure to produce
	bytecode.

	* generic/tclBinary.c (FormatNumber):
	Dredge the NaN out of the internal representation if
	Tcl_GetDoubleFromObj returns TCL_ERROR on a NaN.

	* generic/tclObj.c (Tcl_GetDoubleFromObj):
	Restored silent overflow/underflow behaviour that the merge
	of 2004-04-25 messed up.  Thanks to Don Porter for calling
	attention to this bug. Also removed an uninitialised memory
	reference in this function that valgrind caught. Also changed
	to return TCL_ERROR on a pure NaN.

	* generic/tclStrToD.c (RefineResult):
	Added a test for the initial approximation being HUGE_VAL;
	this test avoids EDOM being returned from ldexp on some platforms
	on input values exceeding the floating point range.

	* tests/expr.test (expr-29.*, expr-30.*):
	Added further tests of overflow/underflow on input conversions.

	* compat/string.h: fixed memchr() protoype for __APPLE__ so that we
	build on Mac OS X 10.1 again.

	* generic/tclNotify.c (TclFinalizeNotifier): fixed notifier not being
	finalized in unthreaded core (was testing for notifier initialization in
	current thread by checking thread id != 0 but thread id is always 0 in
	untreaded core).

	* win/tclWinNotify.c (Tcl_WaitForEvent):
	* unix/tclUnixNotfy.c (Tcl_WaitForEvent): don't call ScaleTimeProc for
	zero wait times (as specified in TIP 233).

	* unix/Makefile.in: added @[email protected] to SRCS and split out NOTIFY_SRCS
	from UNIX_SRCS for parity with UNIX_OBJS & NOTIFY_OBJS.

	* unix/tcl.m4 (Darwin): added configure checks for recently added linker
	flags -single_module and -search_paths_first to allow building with
	older tools (and on Mac OS X 10.1), use -single_module in SHLIB_LD and
	not just T{CL,K}_SHLIB_LD_EXTRAS, added unexporting from Tk of symbols
	from libtclstub to avoid duplicate symbol warnings, added PLAT_SRCS
	definition for Mac OS X, defined MODULE_SCOPE to __private_extern__.
	(SC_MISSING_POSIX_HEADERS): added caching of dirent.h check.

2005-04-22  Don Porter	<[email protected]>

	The 2005-04-21 changes to Tcl_GetBooleanFromObj were done to bring
	it into agreement with its docs.  Further investigation reveals it
	was the docs that were incorrect.

	* doc/BoolObj.3:	Corrections to the documentation of
	Tcl_GetBooleanFromObj to bring it into agreement with what this
	public interface has always done, including noting the difference
	in function between Tcl_GetBooleanFromObj and Tcl_GetBoolean.

	* generic/tclGet.c:	Revised Tcl_GetBoolean to no longer be a
	wrapper around Tcl_GetBooleanFromObj (different function!).

	* generic/tclObj.c:	Removed TclGetTruthValueFromObj routine
	that was added yesterday.  Revisions so that only
	Tcl_GetBoolean-approved values get the "boolean" Tcl_ObjType.
	This retains the fix for [Bug 1187123].

	* generic/tclInt.h:	Revert most recent change.
	* generic/tclBasic.c:
	* generic/tclCompCmds.c:

	* doc/GetInt.3:	Convert argument "string" to "str" to agree with code.
	Also clarified a few details on int and double formats.
	* generic/tclGet.c:	Radical code simplification.  Converted
	Tcl_GetFoo() routines into wrappers around Tcl_GetFooFromObj().
	Reduces code duplication, and the resulting potential for inconsistency.

	* generic/tclObj.c:	Several changes:

	  - Re-ordered error detection code so all values with trailing
	    garbage receive a "not an integer" message instead of an
	    "integer too large" message.
	  - Removed inactive code meant to deal with strtoul* routines that
	    fail to parse leading signs.  All of them do, and if any are
	    detected that do not, the correct fix is replacement with
	    compat/strtoul*.c, not a lot of special care by the callers.
	  - Tcl_GetDoubleFromObj now avoids shimmering away a "wideInt" intrep.
	  - Fixed Tcl_GetBooleanFromObj to agree with its documentation and
	    with Tcl_GetBoolean, accepting only "0" and "1" and not other
	    numeric strings.  [Bug 1187123]
	  - Added new private routine TclGetTruthValueFromObj to perform
	    the more permissive conversion of numeric values to boolean
	    that is needed by the [expr] machinery.

	* generic/tclInt.h (TclGetTruthValueFromObj):	New routine.
	* generic/tclExecute.c:	Updated callers to call new routine.
	* generic/tclBasic.c:	Updated callers to call new routine.
	* generic/tclCompCmds.c:	Updated callers to call new routine.
	* generic/tclDictObj.c:	Updated callers to call new routine.
	* tests/obj.test:	Corrected bad tests that actually expected
	values like "47" and "0xac" to be accepted as booleans.

	* generic/tclLiteral.c:	Disabled the code that forces some literals
	into the "int" Tcl_ObjType during registration.	 We can re-enable it
	if this change causes trouble, but it seems more sensible to let
	Tcl's "on-demand" shimmering rule, and not try to pre-guess things.

	* generic/Var.c (Tcl_ArrayObjCmd - ARRAY_NAMES): fix Tcl_Obj leak
	[Bug 1084111]

2005-04-16  Zoran Vasiljevic <[email protected]>

	* generic/tclIOUtil.c: force clenaup of the interp result
	in TclLoadFile(). Some implementations of TclpFindSymbol()
	will seed the interp result with error message when unable
	to find the requested symbol (this is not considered to
	be an error).

	Set of changes correcting huge memory waste (not a leak)
	when a thread exits. This has been introduced in 8.4.7
	within an attempt to correctly cleanup after ourselves when
	Tcl library is being unloaded with the Tcl_Finalize() call.

	This fixes the Tcl Bug #1178445.

	* generic/tclInt.h: added prototypes for TclpFreeAllocCache()
	and TclFreeAllocCache()

	* generic/tclThreadAlloc.c: modified TclFinalizeThreadAlloc()
	to explicitly call TclpFreeAllocCache with the NULL-ptr as
	argument signalling cleanup of private tsd key used only by
	the threading allocator.

	* unix/tclUnixThrd.c: fixed TclpFreeAllocCache() to recognize
	when being called with NULL argument. This is a signal for it
	to clean up the tsd key associated with the threading allocator.

	* win/tclWinThrd.c: renamed TclWinFreeAllocCache to TclpFreeAllocCache
	and fixed to recognize when being called with NULL argument.
	This is a signal for it to clean up the tsd key associated with the
	threading allocator.

2005-04-13  David Gravereaux <[email protected]>

	* generic/tclIO.c (Tcl_SetChannelBufferSize): Lowest size limit
	* tests/io.test:	changed from ten bytes to one byte.  Need
	* tests/iogt.test:	for this change was proven by
	Ross Cartlidge <[email protected]> where [read stdin 1] was grabbing
	10 bytes followed by starting a child process that was intended to
	continue reading from stdin.  Even with -buffersize set to one,
	nine chars were getting lost by the buffersize over reading for
	the native read() caused by [read].

2005-04-13  Don Porter	<[email protected]>

	* unix/tclUnixInit.c (TclpGetEncodingNameFromEnvironment):  Reversed
	order of verifying candidate [encoding system] value, checking against
	a table in memory first before calling Tcl_GetEncoding and potentially
	scanning through the filesystem.  Also ordered the table so that a
	binary search could be used within it.	Improves startup time a bit
	more on some systems.

	This is all following comments from Steve Manning <[email protected]>
	on comp.lang.tcl that the current documentation was not clear.

	* generic/tclCompile.c:Commented out the functions
	TclPrintInstruction(), TclPrintObject() and TclPrintSource() when
	not debugging the compiler, as they are never called in that case.

2005-04-12  Don Porter	<[email protected]>

	* generic/tclInterp.c:	Corrected bad syntax of Tcl_Panic() call.

	* generic/tclUtil.c (TclGetProcessGlobalValue):	More robust handling
	of bad TclInitProcessGlobalValueProc behavior; an immediate panic
	rather than a mysterious crash later.

	* generic/tclEncoding.c:	Several changes to the way the
	encodingFileMap cache is maintained.  Previously, it was attempted
	to keep the file map filled and up to date with changes in the
	encoding search path.  This contributed to slow startup times since
	it required an expensive "glob" operation to fill the cache.  Now the
	validity of items in the cache are checked at the time they are
	used, so the cache is permitted to fall out of sync with the
	encoding search path.  Only [encoding names] and Tcl_GetEncodingNames()
	now pay the full expense.  [Bug 1177363]

2005-04-12  Kevin B. Kenny  <[email protected]>

	* compat/strstr.c: Added default definition of NULL to

	to (a) reduce the malloc/free calls at list creation (from 2 to
	1), (b) reduce the cost of handling empty lists (we now never
	create a list internal rep for them), (c) allow refcounting of the
	list internal rep. The latter permits insuring that the pointers
	returned by Tcl_ListObjGetElements remain valid even if the object
	shimmers away from its original list type. This is [Patch 1158008]

	* generic/tclExecute.c:

	* generic/tclObj.c:
	* generic/tclStringObj.c:
	(1) defined new internal macros for creating and setting
	frequently used obj types (int,long, wideInt, double,
	string). Changed TEBC to use eg 'TclNewIntObj(objPtr, i)' to avoid
	the function call in 'objPtr = Tcl_NewIntObj(i)'
	(2) ExecEnv now stores two Tcl_Obj* pointing to the constants "0"
	and "1", for use by TEBC.
	(3) slight reduction in cost of INST_START_CMD

	"Thread 1.0" when the [::testthread] command is defined.  It's
	never used by anything, and conflicts with loading the real
	"Thread" package.

2005-03-18  Don Porter	<[email protected]>

	* generic/tclCompCmds.c (TclCompileIncrCmd):	Corrected checks

	* generic/tclUtil.c (Tcl_PrintDouble):
		Changed the signature of TclDoubleDigits so that it

		returns the signum via that pointer.  Added very
		hacky code to handle IEEE signed zeroes in Tcl_DoubleDigits.
		(It can't be done other than as a hack until C9x;

		Added output conversion of tagged NaN values.

	* tests/expr.test: Added tests for the smallest representible
	    value, and rounding between it and zero. (The tests reflect

	* tools/fix_tommath_h.tcl: (New file) Script to edit
				   libtommath/tommath.h and produce
				   generic/tommath.h so that storage
				   classes, allocation routines, and
				   data types conform to Tcl's
				   conventions.
	* generic/tommath.h: (New file) Generated by the above.

	* generic/tclTomMath.h: (New file) Additional declarations
				to be included in tommath.h when building
				Tcl.

	* generic/tclTomMathInterface.c: (New file) Small 'glue' routines
					 adapting tommath's API to Tcl.

	* libtommath/bn_fast_s_mp_mul_digs.c:
	* libtommath/bn_mp_mul_d.c:
	* libtommath/bn_mp_read_radix.c:
	* libtommath/tommath.h: Applied suggested changes from Tom St
	Denis that correct an off-by-one error in single-digit
	multiplication (leading to a pointer smash if uncorrected) and
	change the string argument to 'mp_read_radix' from 'char*' to
	'const char*'.

	* libtommath/bn_mp_radix_size.c:
	Local patch to ensure that sufficient memory is requested
	even if the number has a single digit.

	* libtommath/bn_mp_read_radix.c:
	Local patch to return MP_VAL if the input string contains
	an invalid character.

	* generic/tclObj.c: Added accessor functions for bignums.
	* generic/tclTestObj.c: Added a 'testbignumobj' command to
	exercise the accessor functions for bignums.

	* win/Makefile.in: Added rules for making libtommath.

2005-01-19  Mo DeJong  <[email protected]>

	* win/tclWinChan.c (FileCloseProc): Invoke TclpCutFileChannel() to
	remove a FileInfo from the thread local list before deallocating
	it.  This should have been done via an earlier call to
	Tcl_CutChannel, but I was running into a crash in the next call to
	Tcl_CutChannel during the IO finalization stage.

	* generic/tclFileName.c: fix for glob failure on Windows shares
	[Bug 1100542].

	* doc/pkgMkIndex.n: added documentation that 'pkg_mkIndex -lazy' is
	not a good idea. [Bug 1101678]

2005-01-12  Donal K. Fellows  <[email protected]>

	* unix/tcl.m4 (SC_PATH_{TCL,TK}CONFIG): Added code to detect the

	they now complain but keep working. [FRQ 951247]

			     with a corresponding adjustment to the year.
			     [Bug 1092789]
	* tests/clock.test: Added regression test cases for the above two

	* generic/tclCompile.c: moved TclInitCompiledLocals to tclProc.c
	* generic/tclProc.c: new static InitCompiledLocals to allow for a
	single pass over the proc's arguments at proc load time (instead of
	two as previously). TclObjInterpProc() now allocates the
	compiledLocals on the tcl execution stack, using the new
	TclStackAlloc/Free functions.

2004-12-16  Donal K. Fellows  <[email protected]>

	* generic/tclInterp.c (Tcl_LimitSetTime, TimeLimitCallback):
	(TclLimitRemoveAllHandlers, TclInitLimitSupport): Set a timer
	event to trigger when the time limit runs out. All the time limit
	actually does is check to see if the time limit has been exceeded,
	but this is enough to fix [Bug 1085023].
	* generic/tclInt.h (struct Interp): Added a field to hold the token
	for the timer event handler associated with the current time limit.
	* generic/tclEvent.c (Tcl_UpdateObjCmd, Tcl_VwaitObjCmd): Add
	error message when limit exceeded.
	* tests/interp.test (interp-34.[89]): Check that time limits
	handle the two cases reported in [Bug 1085023]

	* generic/tclTimer.c (TclCreateAbsoluteTimerHandler): New internal
	function that allows setting a timer handler that will be
	triggered at (or after) a specific time instead of at some number
	of milliseconds in the future. This is a candidate for future
	exposure via a TIP.

	of Tcl_PushCallFrame and Tcl_PopCallFrame, but using frames
	allocated in the execution stack - i.e., heap instead of
	C-stack. The core uses these two new functions exclusively; the
	old ones remain for backwards compat, as at least two popular

	* generic/tclCompile.c (TclInitCompiledLocals):
	* generic/tclCompile.h:
	* generic/tclInt.h:
	* generic/tclProc.c (TclObjInterpProc, TclCreateProc): optimised
	loops that initialise a proc's arguments and compiled local

2004-12-10  Donal K. Fellows  <[email protected]>

	* generic/tclInt.h: Move ensemble API decls here from tclNamesp.c

2004-12-09  Donal K. Fellows  <[email protected]>

	* generic/tclNamesp.c (TclMakeEnsembleCmd, TclSetEnsemble*)
	(TclSetEnsemble*, TclFindEnsemble): Build an internal API for

	* doc/Async.3: Reword for better grammar, better nroff and get the
	flag name right. (Reported by David Welton.)

2004-12-07  Don Porter	<[email protected]>

	* tests/unixInit.test (2.1-4):	Added constraints so that when a

2004-12-06  Don Porter	<[email protected]>

	* tests/safe.test:	Trim auto_path to improve performance [1080039]

	* tests/msgcat.test:	makeFile/removeFile cleanup [1079117]

2004-12-04  Don Porter	<[email protected]>

	* generic/tclEncoding.c:	Different fix for [Bug 1077005].
	* generic/tclEvent.c:	Broke apart TclpSetInitialEncodings() on
	* generic/tclInt.h:	Windows into TclpSetInterfaces(), that is
	* unix/tclUnixInit.c:	fundamentally essential, and the initialization
	* win/tclWinInit.c:	of the system encoding, which is not.  Made
	the TclpSetInterfaces call part of TclInitSubsystems so it cannot be
	overlooked.

2004-12-03  Jeff Hobbs	<[email protected]>

	* changes: updated for 8.5a2 release

2004-12-02  Don Porter	<[email protected]>

	* generic/tclUtil.c (TclSetProcessGlobalValue):	 Handle the case
	where a ProcessGlobalValue might be assigned to itself.

	* generic/tclEncoding.c (MakeFileMap):	Correct refcounting errors
	managing values returned by TclPathPart (with refCount of 1!) that
	led to a memory leak.  [Bug 1077474].

2004-12-02  Vince Darley  <[email protected]>

	* generic/tclPathObj.c: fix and new tests for [Bug 1074671] to
	* tests/fileSystem.test:   ensure tilde paths are not returned
	specially by 'glob'.

2004-12-02  Kevin B. Kenny  <[email protected]>

	* win/Makefile.in: Added a 'sed' in the setting of ROOT_DIR_NATIVE
	to compensate for a bug in cygpath (at least version 1.36) that
	leaves a trailing backslash on the end of the converted path.

2004-12-02  Donal K. Fellows  <[email protected]>

	* generic/tclInterp.c (Alias,Target,Master): Rewrote these so that
	the aliases that refer to an interpreter are stored in a list and
	not a hashtable (which was only ever a convenience, and forced the
	use of a global mutex to generate keys!) [FRQ 1077210]
	* generic/tclNamesp.c (numNsCreated): Moved into thread-local
	storage to remove a global mutex. [FRQ 1077210]

2004-12-01  Don Porter	<[email protected]>

	* generic/tclUtil.c (TclGetProcessGlobalValue):	Narrowed the scope
	of mutex locks.

	* generic/tclUtil.c:		Updated Tcl_GetNameOfExecutable() to
	* generic/tclEncoding.c:	make use of a ProcessGlobalValue for
	* generic/tclEvent.c:		storing the executable name.

2004-12-01  Donal K. Fellows  <[email protected]>

	* tests/winDde.test: Rewritten to use tcltest2 features more
	thoroughly (reducing the [catch] count!) and fix the problem with
	winDde-6.1 being out of synch with the implementation.

2004-11-30  Don Porter	<[email protected]>

	* library/init.tcl ([unknown]):	Restored the save/restore of
	the variables ::errorCode and ::errorInfo.  This is needed when
	the [::bgerror] command is auto-loaded (as it is by Tk).

	Patch 976520 reworks several of the details involved with
	startup/initialization of the Tcl library, focused on the
	activities of Tcl_FindExecutable().

	* generic/tclIO.c:	Removed bogus claim in comment that
	encoding "iso8859-1" is "built-in" to Tcl.

	* generic/tclInt.h:	Created a new struct ProcessGlobalValue,
	* generic/tclUtil.c:	routines Tcl(Get|Set)ProcessGlobalValue,
	and function type TclInitProcessGlobalValueProc.  Together, these
	take care of the housekeeping for "values" (things that can be
	held in a Tcl_Obj) that are global across a whole process.  That is,
	they are shared among multiple threads, and epoch and mutex
	protection must govern the validity of cached copies maintained
	in each thread.

	* generic/tclNotify.c:	Modified TclInitNotifier() to tolerate
	being called multiple times in the same thread.

	* generic/tclEvent.c:	Dropped the unused argv0 argument to
	TclInitSubsystems().  Removed machinery to unsure only one
	TclInitNotifier() call per thread, now that that is safe.
	Converted Tcl(Get|Set)LibraryPath to use a ProcessGlobalValue,
	and moved them to tclEncoding.c.
	* generic/tclBasic.c:	Updated caller.

	* generic/tclInt.h:	TclpFindExecutable now returns void.
	* unix/tclUnixFile.c:
	* win/tclWinFile.c:
	* win/tclWinPipe.c:

	* generic/tclEncoding.c: Built new encoding search initialization
	on a foundation of ProcessGlobalValues, exposing new routines
	Tcl(Get|Set)EncodingSearchPath.	 A cache of a map from encoding name
	to directory pathname keeps track of where encodings are available
	for loading.  Tcl_FindExecutable greatly simplified into just
	three function calls.  The "library path" is now misnamed, as its
	only remaining purpose is as a foundation for the default encoding
	search path.

	* generic/tclInterp.c:	Inlined the initScript that is evaluated
	by Tcl_Init().	Added verification after initScript evaluation
	that Tcl can find its installed *.enc files, and that it has
	initialized [encoding system] in agreement with what the environment
	expects.  [tclInit] no longer driven by the value of $::tcl_libPath;
	it largely constructs its own search path now, rather than attempt
	to share one with the encoding system.

	* unix/tclUnixInit.c:	TclpSetInitialEncodings factored so that a new
	* win/tclWinInit.c:	routine TclpGetEncodingNameFromEnvironment
	can reveal that Tcl thinks the [encoding system] should be, even
	when an incomplete encoding search path, or a missing *.enc file
	won't allow that initialization to succeed.  TclpInitLibraryPath
	reworked as an initializer of a ProcessGlobalValue.

	* unix/tclUnixTest.c:	Update implementations of [testfindexecutable],
	[testgetdefenc], and [testsetdefenc].

	* tests/unixInit.test:	Corrected tests to operate properly even
	when a value of TCL_LIBRARY is required to find encodings.

	* generic/tclInt.decls:	New internal stubs: TclGetEncodingSearchPath,
	TclSetEncodingSearchPath, TclpGetEncodingNameFromEnvironment.  These
	are candidates for public exposure by future TIPs.

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

	* generic/tclTest.c:	Updated [testencoding] to use
	* tests/encoding.test:	Tcl(Get|Set)EncodingSearchPath.	 Updated tests.

2004-11-30  Kevin B. Kenny  <[email protected]>

	* library/clock.tcl: Corrected the regular expressions that match
	a time zone to allow for time zones specified as +HH or -HH.
	* tests/clock.test: Added regression test case for the above issue.
	Thanks to Rolf Ade for reporting this issue
	[http://wiki.tcl.tk/13094]
	* win/tclWinDde.c (Tcl_DdeObjCmd): Corrected a typo that caused a
	compilation failure on VC++.

2004-11-29  Andreas Kupries <[email protected]>

	* win/Makefile.in (install-libraries): Brought entry '2004-10-26
	  Don Porter (Tcl Modules)' into the windows world, actually the
	  win/configure buildsystem. The other windows buildsystems (.vc,
	  .bc) still have to be updated as well.

2004-11-26  Andreas Kupries <[email protected]>

	* win/tclWinDde.c (ExecuteRemoteObject): Removed bogus semicolon
	  found at the end of the header for the function definition,
	  terminating it early and preventing a compile. This is likely a
	  fix for '2004-11-25 Donal'. I have to conclude that it is also
	  unknown if the other changes to this file actually pass the
	  testsuite. Running testsuite ... They don't. winDde-6.1
	  fails. This is only a message discrepance, i.e. not too
	  bad. Leaving resolution of that to Pat and Donal.

2004-11-26  Don Porter	<[email protected]>

	* library/auto.tcl (tcl_findLibrary):	Made sure the uniquifying
	operations on the search path does not also normalize.	[Bug 1072136]

2004-11-26  Donal K. Fellows  <[email protected]>

	* unix/configure.in: Simplify the code to check for correctness of
	strstr, strtoul and strtod.
	* unix/tcl.m4 (SC_TCL_CHECK_BROKEN_FUNC): Split a complex stanza
	out of configure.in into its own function. Also force it to do the

	be fixed as well. Done with a load of #ifdef-ery because this hack
	is so ugly nobody should keep it around once Itcl's fixed.

2004-11-25  Reinhard Max  <[email protected]>

	* tests/tcltest.test: The order in which [glob] returns the file
	names is undefined, so tests should not depend on it.

2004-11-25  Zoran Vasiljevic <[email protected]>

	* doc/Thread.3:
	* doc/Notifier.3: Added changes from the core-8-4-branch

2004-11-25  Donal K. Fellows  <[email protected]>

	* unix/tclUnixNotfy.c: Corrected all uses of 'select' to
	manage their masks using the FD_CLR, FD_ISSET, FD_SET, and
	FD_ZERO macros rather than bit-whacking that failed under
	Solaris-Sparc-64.  [Bug 1071807]
	* win/tclWinInit.c (TclpInitLibraryPath): Removed unused
	vars 'pathc' and 'pathv' that caused compilation problems
	on VC++ with --enable-symbols.

2004-11-24  Don Porter	<[email protected]>

	* unix/tcl.m4 (SC_ENABLE_THREADS):	Corrected failure to determine
	the number of arguments for readdir_r on SunOS systems.	 [Bug 1071701]

	* unix/configure:	autoconf-2.57

	* generic/tclCmdIL.c (InfoVarsCmd):	Corrected segfault in new
	* tests/info.test (info-19.6):	trivial matching branch [Bug 1072654]

2004-11-24  Donal K. Fellows  <[email protected]>

	* unix/tcl.m4 (SC_ENABLE_THREADS): Check for a 2
	argument version of readdir_r that is known to
	exists under IRIX 5.3.
	* unix/tclUnixThrd.c (TclpReaddir): Use either
	2 arg or 3 arg version of readdir_r.
	[Bug 1001325]

2004-11-22  Don Porter	<[email protected]>

	* unix/tclUnixInit.c (TclpInitLibraryPath):	Purged dead code that
	* win/tclWinInit.c (TclpInitLibraryPath):	used to extend the
	"library path".	 Search path construction for init.tcl is now done
	within the [tclInit] proc.

	* generic/tclInterp.c:	Restored several directories to the search
	* tests/unixInit.test:	path used to locate init.tcl within [tclInit].
	This change does not restore any directories to the encoding search
	path, so should still avoid the price of an unreasonably large number
	of filesystem accesses during encoding initialization at startup
	[Bug 976438]

	* doc/SaveResult.3:	and to the ::bgerror command with references

	* doc/update.n:

	* tests/unixInit.test:	Removed "knownBug" constraints to prompt
	bug fixing before 8.5a2 release.

2004-11-19  Daniel Steffen  <[email protected]>

	* macosx/Makefile:
	* unix/configure.in:
	* unix/tclUnixInit.c (MacOSXGetLibraryPath): changed detection
	of tcl framework build when determining tclLibPath from overloaded
	TCL_LIBRARY to configuration define TCL_FRAMEWORK. [Bug 1068088]

	* unix/configure: autoconf-2.57
	* unix/tclConfig.h.in: autoheader-2.57

2004-11-18  Don Porter	<[email protected]>

	* doc/SaveResult.3:	Documentation for Tcl_*InterpState (TIP 226).

	* generic/tclEvent.c (HandleBgErrors):	Simplified program flow.

	* tests/basic.test:	Updated functional (not testing) uses of

	* generic/tclInterp.c:	Corrected [interp bgerror] error messages.

2004-11-18  Reinhard Max  <[email protected]>

	* unix/tcl.m4 (SC_CONFIG_MANPAGES): Applied an improved version of
	* unix/configure.in:		    patch #996085, that introduces
	* unix/Makefile.in:		    --enable-man-suffix.

	* unix/installManPage:		    added
	* unix/mkLinks.tcl:		    removed
	* unix/mkLinks:			    removed
	* unix/configure:		    generated

	* unix/Makefile.in:		    Don't install tclConfig.h .

2004-11-17  Don Porter	<[email protected]>

	* unix/configure.in:	The change below reveals that the public
	data type Tcl_StatBuf relies on config information.  For now,
	disabled the use of the tclConfig.h file until its full impact
	on Tcl's interface can be assessed.

	* unix/configure:	autoconf-2.57

	* generic/tcl.h:	Moved the #include "tclConfig.h" out of
	* generic/tclInt.h:	tcl.h.	The config settings are not part of
	* generic/tclPort.:	the public interface, and having it there
	breaks compiled against uninstalled Tcl and extensions using
	autoconf-2.5*.

2004-11-16  Jeff Hobbs	<[email protected]>

	* unix/tclUnixChan.c (TtySetOptionProc): fixed crash configuring
	-ttycontrol on a channel. [Bug 1067708]

2004-11-16  Don Porter	<[email protected]>

	* generic/tclIOUtil.c (TclFSEpochOk):	There were two code paths
	via which the thread copy of filesystemEpoch could be synched with
	the master copy, but only one kept the filesystem list cache up
	to date.  Fix routes everything through	 a single code path.
	[Bug 1035775].

2004-11-16  Donal K. Fellows  <[email protected]>

	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Stop architecture flags to 'ld'
	from getting lost when [load] is disabled. [Bug 1016796]

2004-11-16  Daniel Steffen  <[email protected]>

	* generic/tcl.h:

	* unix/configure: autoconf-2.57

2004-11-15  Don Porter	<[email protected]>

	* generic/tclInt.h:	Added comment warning that the old
	ERR_IN_PROGRESS and ERROR_CODE_SET flag values should not be re-used
	for the sake of those extensions that have accessed them.

	* generic/tclCmdMZ.c (Tcl_TraceObjCmd): Fixed Bug 1065378 which failed
	* tests/trace.test (trace-33.1):	to permit a variable trace
	created with [trace variable] to be destroyed with [trace remove].
	Thanks to Keith Vetter for the report.

2004-11-15  Donal K. Fellows  <[email protected]>

	* doc/tclvars.n: Added section to documentation on global
	variables that are specific to tclsh and wish. [Patch 1065732]

2004-11-12  Jeff Hobbs	<[email protected]>

	* generic/tclEncoding.c (TableFromUtfProc): correct crash

	TIP #226 IMPLEMENTATION
	* generic/tcl.decls:	Stubs for Tcl_(Save|Restore|Discard)InterpState
	* generic/tcl.h:	New public opaque type, Tcl_InterpState.

	* generic/tclIOGT.c:
	* generic/tclTrace.c:

	* generic/tcl.h:
	* generic/tclInt.h:
	* unix/Makefile.in: include tclConfig.h from tcl.h and install it
	as a public header. Normalized compiler include path order to
	-I${BUILD_DIR} -I${UNIX_DIR} -I${GENERIC_DIR}.

	* unix/dltest/Makefile.in: add ${BUILD_DIR}/.. to include path
	to pick up tclConfig.h.

	* unix/tclUnixInit.c: moved check for HAVE_CFBUNDLE define after
	#include "tclInt.h" to ensure tclConfig.h has been included.

2004-11-12  Reinhard Max  <[email protected]>

	* unix/config.h.in:
	* unix/tclConfig.h.in:	renamed

	* unix/Makefile.in:	Completed support for config header,
	* unix/configure.in:	fixed building outside of the unix dir,
	* unix/tclAppinit.c:	and reflected the name change of config.h.
	* generic/tclInt.h:

	* unix/configure:	generated

2004-11-12  Donal K. Fellows  <[email protected]>

	* unix/config.h.in:	Allow configure to put all the C #defs into
	* unix/configure.in:	a file (called config.h) so that Unix builds
	* unix/tcl.m4:		now take far fewer lines of scrollback to
	* unix/Makefile.in:	proceed (making it less likely that any errors

	are still very cryptic, but they appear to have to be that way.
	The number of skipped tests has increased, but now the skipped
	tests have much more meaningful content.

	* tests/tm.test (genpaths): Add a [file normalize] so we pick up
	Windows drive letters, etc. [Bug 1053568]

2004-11-04  Don Porter	<[email protected]>

	* changes:	Updates toward an 8.5a2 release.

2004-11-03  Kevin B. Kenny  <[email protected]>

	"Monday" with a base time other than midnight incorrectly carried

	* win/tclWinPort.h:		to prior the inclusion of the Stubs
	headers as they are now resetting TCL_STORAGE_CLASS.  Removed
	extrainious reset from tclWinPort.h.  [Patch 1055668]

	* generic/tclCompile.h: Removed	extrainious reset of
	TCL_STORAGE_CLASS missed in my last edit.

2004-11-03  Don Porter	<[email protected]>

	* library/init.tcl ([unknown]):	Corrections to the 2004-10-25 mods
	to Aunt ??? in [unknown].  Flaws revealed by Itcl test suite, which
	still apparently relies on this brokenness.  Also added comment
	suggesting the error message that any code using this hack *ought*
	to receive in reply.

	* generic/tclInt.h: added a check for #ifdef __cplusplus around
	the #define of MODULE_SCOPE.  About the only time it would be
	problem is when someone is statically linking to Tcl and accessing
	internals from a C++ file and has name mangling issues from the
	lack of "C" after 'extern' [Patch 1055668].
	* generic/tclCompile.h: Exchanged use of the EXTERN macro to the
	new MODULE_SCOPE macro.	 Lowered exported internals count by 35.
	[Patch 1055668]
	* win/tclWinInt.h:
	* win/tclWinPort.h: exported internals dropped by a count of 14.
	* generic/tclFileSystem.h: Added use of MODULE_SCOPE on protos.
	* generic/tclRegexp.h: manipulating TCL_STORAGE_CLASS unnecessary.

2004-11-02  Don Porter	<[email protected]>

	* library/tcltest/tcltest.tcl:		Corrected some misleading
	* tests/tcltest.test (tcltest-26.1,2):	displays of ::errorInfo and
	::errorCode information when the -setup, -body, and/or -cleanup scripts
	return an unexpected return code.  Thanks to Robert Seeger for the
	fix. [RFE 1017151].

2004-11-02  Donal K. Fellows  <[email protected]>

	* library/tzdata/America/Cuiaba: Change to DST rules for
	* library/tzdata/America/Havana: autumn of 2004.
	[ftp://elsie.nci.nih.gov/pub/tzdata2004g.tar.gz]

	* tools/tclZIC.tcl: Updated to be compatible with recent
	changes in library/clock.tcl.

2004-11-02  Vince Darley  <[email protected]>

	* win/tclWinFile.c: Simplify TclpUtime to use Tcl_FSGetNativePath,
	and add comments.

2004-11-02  Donal K. Fellows  <[email protected]>

	* generic/tclInt.h: Change uses of EXTERN to MODULE_SCOPE (defined
	in this file too to be 'extern' if not overridden) as nothing
	declared in tclInt.h is supposed to be visible outside the Tcl

	* tests/io.test (io-40.3): Convert umask2 test constraint into a
	form that most people will be able to satisfy.

	* tests/cmdAH.test (cmdAH-8.45): Removed broken test constraint.
	It didn't do what it was intended to do, and it implied the other
	correct constraint. [Bug 1053908]

	* generic/tclCmdIL.c (InfoGlobalsCmd):
	* tests/info.test (info-8.4): Strip leading global-namespace
	specifiers from the pattern argument. [Bug 1057461]

2004-10-30  Kevin Kenny	 <[email protected]>

	* generic/clock.c: Replaced WIN32 macro with __WIN32__.
	[Bug 1054357].	Thanks to David Gravereaux for the patch.
	* win/tclWinFile.c: Removed a long-standing bug that causes
	incorrect conversion between file time and UTC time if
	the file time is recorded in a different Daylight Saving Time
	status than the current one. [Bug 926106]

2004-10-29  Don Porter	<[email protected]>

	* library/tcltest/tcltest.tcl:	Correct reaction to errors in the
	obsolete processCmdLineArgsHook.	[Bug 1055673]
	* library/tcltest/pkgIndex.tcl:	Bump to tcltest 2.2.7
	* unix/Makefile.in:
	* tests/all.tcl:	Update to use [tcltest::configure].

	in doing this.

	* tests/namespace.test (namespace-50.*): Tests of ensemble
	subcommand error message rewriting.
	* generic/tclProc.c (TclObjInterpProc): Make procedures implement
	their wrong-num-args message using Tcl_WrongNumArgs instead of
	something baked-at-home.
	* generic/tclNamesp.c (TclIsEnsemble, NsEnsembleImplementationCmd):
	Added test of ensemble-hood (available to rest of core) and made
	ensembles set up the rewriting for Tcl_WrongNumArgs to take
	advantage of.
	* generic/tclInt.h (Interp.ensembleRewrite): Extra fields.
	* generic/tclIndexObj.c (Tcl_WrongNumArgs): Add knowledge of what
	is going on in ensembles' command rewriting so this command can
	generate the right error message itself.
	* generic/tclBasic.c (Tcl_CreateInterp, TclEvalObjvInternal):
	Added code to initialize (as empty) the rewriting fields and reset
	them when we leak outside an ensemble implementation.

2004-10-28  Miguel Sofer <[email protected]>

	* generic/tclExecute.c (INST_START_CMD):
	* tests/execute.test (execute-8.3): fix for execution stack
	corruption [Bug 1055676]. Credit dgp for detective work and fix.

2004-10-27  Don Porter	<[email protected]>

	* tests/socket.test (socket-13.1):	Balanced [makeFile] and
	[removeFile] commands.

	* tests/clock.test:	Correct duplicate test names.
	* tests/namespace.test:
	* tests/string.test:
	* tests/io.test (io-50.4):	Use namespace variables.

	* tests/tm.test:  Expanded on the testsuite entered by Donal.
	* library/tm.tcl: Even found bugs, these have been corrected.

2004-10-26  Kevin Kenny <[email protected]>

	* tests/format.test (format-19.1): Additional regression test for
					   Bug 868489.

2004-10-27  Donal K. Fellows  <[email protected]>

	* doc/*.n: Many small general documentation fixes.

2004-10-26  David Gravereaux <[email protected]>

	* generic/tclPipe.c (TclCleanupChildren): bad cast of resolvedPid
	caused PIDs on win95 to go negative.  winpipe-4.2 brought this to
	the surface.  Fixed with sprintf in place of TclFormatInt.  Thanks
	to hgiese [Patch 767676]

2004-10-26  Andreas Kupries <[email protected]>

	* library/tm.tcl (::tcl::tm::Defaults): Added a second [file
	  dirname] around the location of the executable. This fixes [Tcl
	  SF Bug 1038705]. Instable of a bogus "foo/bin/lib" we now have
	  the correct "foo/lib" as a base path for modules.

2004-10-26  Don Porter	<[email protected]>

	* generic/tclParse.c (Tcl_SubstObj):	Fix for failed subst-12.3 test.
	* tests/subst.test (subst-12.3-5):	More tests for Bug 1036649.

	* unix/Makefile.in (install-libraries): Updated the installation
	of the http, msgcat, and tcltest packages to install as Tcl Modules
	on Unix systems.  Other platform Makefiles still need updating.
	[Patch 1054370]

	* tests/basic.test:	Added missing constraints.

	single characters. [Bug 1048005]
	* doc/info.n (procs): Clarified that the pattern argument may have
	namespace separators in it. [Bug 1047928]

	* tests/cmdAH.test (cmdAH-8.45): Simplify in the hope that the
	reasons for [Bug 1053908] will become clearer.

2004-10-25  Don Porter	<[email protected]>

	* generic/tclExecute.c (IllegalExprOperandType,TclExecuteByteCode):
	Removed several DECACHE_INFO/CACHE_INFO pairs that are no longer
	needed for protection because routines like Tcl_SetErrorCode() and
	Tcl_AddErrorInfo() can no longer re-enter bytecode execution.

	* generic/tclResult.c (TclProcessReturn): Bug fix.  Be sure that

	* library/clock.tcl	remaining references to global vars
	* library/init.tcl	::errorInfo and ::errorCode.

	* generic/tclMain.c (Tcl_Main):	Updated to make use of
	TclGetReturnOptions instead of ::errorInfo variable.

	* generic/tclInterp.c (tclInit): Bug fix.  Access dict variables
	with [dict get], not array syntax.

2004-10-25  Donal K. Fellows  <[email protected]>

	* tests/tm.test: Rewrote the tests to actually perform syntax
	checks on the public API. Added a new test (currently failing) to
	indicate that the test suite is not complete yet.
	* library/tm.tcl (path): Rewrote to turn this command into an
	ensemble to make it faster and simpler.

2004-10-24  Miguel Sofer <[email protected]>

	* generic/tclCmdIL.c:
	* generic/tclExecute.c:
	* generic/tclInt.h:
	* generic/tclTrace.c: defined new macros to get/set the flags of
	variables. The only files that still access the flag values
	directly are tclCompCmds.c, tclCompile.c, tclProc.c and tclVar.c

2004-10-24  Don Porter	<[email protected]>

	* generic/tclBasic.c (Tcl_LogCommandInfo,Tcl_AddObjErrorInfo):
	Shift the initialization of errorCode to NONE to more central
	location.

	* generic/tclEvent.c (BgError,Tcl_BackgroundError,HandleBgErrors):
	Rewrite to build on the new TclGet/SetReturnOptions routines.

	* tests/clock.test: Added regression test cases that covers
	both bugs.
	Thanks to Todd M. Helfter <[email protected]> for
	finding these bugs.

2004-10-22  Donal K. Fellows  <[email protected]>

	* generic/tclExecute.c (TclCompEvalObj, Tcl_ExprObj):
	* generic/tclProc.c (TclProcCompileProc): Always call object
	freeIntRepProc's in the same way.

2004-10-22  Miguel Sofer <[email protected]>

	* generic/tclVar.c: fixed bug in commit of 2004-07-23, which was
	causing a leak of Proc structures and failure of compile-12.1. Two
	lines were 'zombies' from the previous way localVarNames
	worked. Credit dgp for finding this.

2004-10-21  Don Porter	<[email protected]>

	* generic/tclInt.h (Interp):
	* generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp):
	* generic/tclResult.c (GetKeys,ReleaseKeys,etc.):
	Moved the key values of the return options dictionary out of
	private fields of the Interp struct and into thread-static
	values managed in tclResult.c.

	* generic/tclResult.c (TclProcessReturn,TclMergeReturnOptions):
	Move internal utility routines from tclCmdMZ.c to tclResult.c.

	* generic/tclBasic.c (Tcl_CreateInterp, Tcl_DeleteInterp):
	* generic/tclResult.c (TclTransferResult):	Rework so that
	iPtr->returnOpts can be NULL when there are no special options.

	* generic/tclResult.c (TclRestoreInterpState):	Plug potential
	memory leak.

2004-10-21  Kevin B. Kenny  <[email protected]>

	* generic/tclBasic.c: Various changes to [clock format] that,
	* generic/tclClock.c: together, make it roughly twice as fast
	* generic/tclInt.h:   while all tests in the test suite
	* library/clock.tcl:  continue to pass.

2004-10-20  Andreas Kupries <[email protected]>

	* win/Makefile.in (install-msgs):   Fixed a problem with the
	* win/Makefile.in (install-tzdata): installation of timezone data
	  and message catalogs. They used the installed tcl library
	  directory, not the source library. Before it was installed.
	  Switched to source lib dir. Thanks to Kevin for the help in
	  figuring this out.

2004-10-20  Don Porter	<[email protected]>

	* generic/tclThreadTest.c (ThreadEventProc):	Corrected subtle
	bug where the returned (char *) from Tcl_GetStringResult(interp)
	continued to be used without copying or refcounting, while
	activity on the interp continued.  That's not safe, and recent
	changes demonstrated the lack of safety with failing tests
	thread-4.3 and thread-4.5.

2004-10-19  Donal K. Fellows  <[email protected]>

	* generic/tclDictObj.c (DictWithCmd): Make sure all paths (that
	are not themselves error paths) do not lose the result code.

2004-10-19  Don Porter	<[email protected]>

	* generic/tclInt.h (Tcl*InterpState):		New internal routines
	* generic/tclResult.c (Tcl*InterpState):	TclSaveInterpState,
	TclRestoreInterpState, and TclDiscardInterpState are superior
	replacements for Tcl_(Save|Restore|Discard)Result.  Intent is that
	these routines will be converted to public routines after TIP approval.
	Interfaces for these routines were shamelessly stolen from Itcl.

	* generic/tclEvent.c (HandleBgErrors):
	* generic/tclFCmd.c (CopyRenameOneFile):
	Calls to Tcl_*Result that were eliminated because they appeared
	to serve no useful purpose, typically saving/restoring an error
	message, only to throw it away.

2004-10-18  Don Porter	<[email protected]>

	* generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp):
	* generic/tclCmdAH.c (Tcl_CatchObjCmd):
	* generic/tclCmdMZ.c (TclMergeReturnOptions,TclProcessReturn):
	* generic/tclCompCmds.c (TclCompileReturnCmd):
	* generic/tclExecute.c (TclCompEvalObj):
	* generic/tclInt.h (Interp):
	* generic/tclProc.c (TclUpdateReturnInfo):
	Place primary storage of the -level and -code information in private
	fields of the Interp struct, rather than in a DictObj.	This should
	significantly improve performance of TclUpdateReturnInfo.

2004-10-17  Miguel Sofer <[email protected]>

	* generic/tclResult.c: removed unused variable [Bug 1048588].
	Thanks to Daniel South.

2004-10-15  Don Porter	<[email protected]>

	* generic/tclCmdMZ.c (TclProcessReturn):	Now that primary
	* generic/tclProc.c (TclUpdateReturnInfo):	storage for the
	errorInfo and errorCode values are internal fields, we can set
	them at the time of the [return] command, and not have to wait
	until the specified number of "-level"s have popped.

		(Tcl_ResetResult,TclTransferResult):
	* generic/tclTrace.c (CallVarTraces):
	Reworked management of the "errorInfo" data of an interp.
	That information is now primarily stored in a new private
	(Tcl_Obj *) field of the Interp struct, rather than using a
	global variable ::errorInfo as the primary storage.  The
	ERR_IN_PROGRESS flag bit value is no longer required to manage
	the value in its new location, and is removed.	Variable traces
	are established to support compatibility for any code expecting
	the ::errorInfo variable to hold the information.

	***POTENTIAL INCOMPATIBILITY***
	Code that sets traces on the ::errorInfo variable may notice a
	difference in timing of the firing of those traces.  Code that
	uses the value ERR_IN_PROGRESS.

	* generic/tclExecute.c (TclExecuteByteCode): Implementation of the
	INST_LIST_IN and INST_LIST_NOT_IN bytecodes.
	* generic/tclParseExpr.c (GetLexeme): Parse the 'in' and 'ni'
	operators for TIP#201.
	* generic/tclDictObj.c (DictUpdateCmd,DictWithCmd): Core of
	implementation of TIP#212; docs and tests still to do...

2004-10-07  Don Porter	<[email protected]>

	* generic/tclTest.c (TestsetobjerrorcodeCmd):  Simplified.

	* generic/tclPathObj.c:
	* unix/tclUnixFile.c:
	* win/tclWinFile.c:
	* tests/fileName.test:
	* tests/winFCmd.test: code reorganization for better generic/
	platform code splitting [Bug 925620] removing the need for
	several #ifdef's, and tests and fix for an unreported Windows
	glob problem ('glob -dir C: -tails *').

2004-10-07  Donal K. Fellows  <[email protected]>

	* *.3: Convert CONST to const and VOID to void so we document how
	people should actually use the Tcl API and not the compatability
	hacks that it has to have.

	the Engineering Manual more closely, and also take advantage of
	the internal object manipulation macros more.

	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Reorganized to have fewer
	magic flag variables and to separate the code that scans for a
	match from the code that processes a match body.

	It is a poor practice to directly set or append to the value
	of the objResult of an interp, because that value might be
	shared, and in that circumstance a Tcl_Panic() will be the
	result.	 Searched for example of this practice and replaced
	with safer alternatives, often using the Tcl_AppendResult()
	routine that dkf just rehabilitated.
	* library/dde/pkgIndex.tcl: Bump to dde 1.3.1
	* library/reg/pkgIndex.tcl: Bump to registry 1.1.5

2004-10-06  Donal K. Fellows  <[email protected]>

	* doc/SetResult.3: Made Tcl_AppendResult non-deprecated; better
	that people use it than most of the common alternatives!
	* generic/tclResult.c (Tcl_AppendResultVA): Make this work better
	with Tcl_Objs. [Patch 1041072]
	(Tcl_SetResult, Tcl_AppendElement): Change string to stringPtr to
	avoid C++ keywords.

2004-10-05  Don Porter	<[email protected]>

	* generic/tclBasic.c (TclObjInvoke): More simplification of the
	TclObjInvoke routine toward unification with the rest of the
	evaluation stack.

	* generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp,
		TclEvalObjvInternal,Tcl_LogCommandInfo):
	* generic/tclCmdAH.c (Tcl_CatchObjCmd):
	* generic/tclEvent.c (BgError,Tcl_BackgroundError,HandleBgErrors):
	* generic/tclInt.h (Interp, ERROR_CODE_SET):
	* generic/tclNamesp.c
		(Tcl_CreateNamespace,Tcl_DeleteNamespace,TclTeardownNamespace):
	* generic/tclResult.c
		(Tcl_ResetResult,Tcl_SetObjErrorCode,TclTransferResult):
	* generic/tclTrace.c (CallVarTraces):
	Reworked management of the "errorCode" data of an interp.
	That information is now primarily stored in a new private
	(Tcl_Obj *) field of the Interp struct, rather than using a
	global variable ::errorCode as the primary storage.  The
	ERROR_CODE_SET flag bit value is no longer required to manage
	the value in its new location, and is removed.	Variable traces
	are established to support compatibility for any code expecting
	the ::errorCode variable to hold the information.

	***POTENTIAL INCOMPATIBILITY***
	Code that sets traces on the ::errorCode variable may notice a
	difference in timing of the firing of those traces.

2004-10-04  Donal K. Fellows  <[email protected]>

	* generic/tclParseExpr.c (GetLexeme): Ensure that the 'eq' and
	'ne' operators are followed by non-alphabetic characters so
	lexemes can't run together. [Bug 884830]

	* doc/DictObj.3, doc/dict.n: Clarified that a dictionary is not
	order-preserving. [Bug 1032243]	 Also added another example to
	show off more ways of using a dictionary and a few other
	formatting improvements.

2004-10-02  Donal K. Fellows  <[email protected]>

	* generic/tclDictObj.c (TraceDictPath, Tcl_DictObjPutKeyList): Add
	support for automatic creation of dictionary paths since that is
	what everyone seems to actually expect of the API! [Bug 1037235]
	(Tcl_DictObjNext): Make calling this after Tcl_DictObjDone non-fatal
	as that simplifies a number of internal APIs. This doesn't break any
	existing working code as it is a case which previously caused a panic.

2004-10-02  Don Porter	<[email protected]>

	* tests/namespace.test (namespace-8.7):	Another test for save/restore
	of ::errorInfo and ::errorCode during global namespace teardown.

2004-10-01  Donal K. Fellows  <[email protected]>

	* generic/tclProc.c (TclObjGetFrame, Tcl_UplevelObjCmd):
	* generic/tclVar.c (Tcl_UpvarObjCmd): Cache stackframe level
	references in the level object for speed.

2004-09-30  Don Porter	<[email protected]>

	* generic/tclBasic.c (Tcl_CreateInterp): Removed the flag bit value
	* generic/tclInt.h (Interp):	EXPR_INITIALIZED.  It was set during
	interp creation and never tested.  Whatever purpose it had is in
	the past.

	* generic/tclBasic.c (Tcl_EvalObjEx):	Removed the flag bit value
	* generic/tclInt.h (Interp):	USE_EVAL_DIRECT.  It was used only
	* generic/tcLTest.c (TestevalexObjCmd):	in the testing command
	* tests/parser.test (parse-9.2): [testevalex] and nothing in the
	test suite made use of the capability it enabled.

	* generic/tclBasic.c (Tcl_AddObjErrorInfo): More re-organization
	* generic/tclCmdAH.c (Tcl_ErrorObjCmd):	    of the management of
	* generic/tclCmdMZ.c (TclProcessReturn):    the errorCode value.
	* tests/error.test (error-6.4-9):

	* generic/tclNamespace.c (TclTeardownNamespace): Tcl_Obj-ified
	* tests/namespace.test (namespace-8.5,6):	the save/restore
	of ::errorInfo and ::errorCode during global namespace teardown.
	Revised the comment to clarify why this is done, and added tests

	* tests/var.test (var-16.1):	values that define part of the
	interpreter state during variable traces.  [Bug 1038021].

2004-09-30  Miguel Sofer <[email protected]>

	* tests/subst.test (12.1-2): added tests for [Bug 1036649]

2004-09-29  Don Porter	<[email protected]>

	* tests/basic.test (49.*):	New tests for TCL_EVAL_GLOBAL.

2004-09-29  Donal K. Fellows  <[email protected]>

	* generic/tclVar.c (TclObjLookupVar, TclObjLookupVar):
	(TclObjUnsetVar2, SetArraySearchObj):

	internal representation to a shared macro, so simplifying much code.

2004-09-27  Miguel Sofer <[email protected]>

	* generic/tclBasic.c (TclObjInvoke): fix for bogus gcc warning
	about uninitialised variable.

2004-09-27  Don Porter	<[email protected]>

	* generic/tclBasic.c:	Removed internal routines TclInvoke,
	* generic/tclInt.decls: TclGlobalInvoke, TclObjInvokeGlobal and
	* tests/basic.test:	the portion of TclObjInvoke that handles
	calls without TCL_INVOKE_HIDDEN enabled.  None of this code is
	called any longer within the core, and the superior public
	interface, Tcl_EvalObjv, is available for any external callers.

	* tests/winFCmd.test: fix to bad error message with 'cd' on
	windows, when permissions are inadequate [Bug 1035462] and
	to treatment of a volume-relative pwd on Windows [Bug 1018980].

	* doc/FileSystem.3: added missing Tcl_GlobTypeData documentation
	[Bug 935853]

2004-09-27  Kevin Kenny	 <[email protected]>

	* compat/strftime.c (Removed):
	* generic/tclClock.c (removed TclClockOldscanObjCmd):
	* generic/tclDate.c (Regenerated):
	* generic/tclGetDate.y:
	* generic/tclInt.decls (removed TclGetDate and TclpStrftime):
	* generic/tclInt.h (removed TclGetDateInfo):
	* generic/tclIntDecls.h (Regenerated):
	* generic/tclStubInit.c (Regenerated):
	* library/clock.tcl:
	* unix/tclUnixTime.c (removed TclpStrftime):
	* win/Makefile.in:
	* win/makefile.bc:
	* win/makefile.bc:
	* win/tcl.dsp:
	Continued refactoring of [clock] for TIP 173 changes.
	Broke the free-form parser apart so that the Bison parser

	have been removed.  The refactoring also has the benefit
	that all storage in the Bison parser is now on the C stack,
	eliminating any need for mutex protection around [clock scan].
	Also, changed the Makefiles so that 'make gendate' is
	available on Windows as well as Unix.

	* generic/tclCmdAH.c (Tcl_FormatObjCmd): Removed some grubby
	* generic/tclObj.c (SetBooleanFromAny):	 work-around code
						 that was needed only
						 because of Bug 868489.

	* generic/tclBasic.c (TclObjInvoke): Removed three unused
	variables to silence a compiler warning in VC++.

2004-09-27  Vince Darley  <[email protected]>

	* doc/FileSystem.3: fix to small typo.

	* generic/tclProc.c:
	* tests/compExpr-old.test:
	* tests/compExpr.test:
	* tests/expr.test:
	* tests/for.test:
	* tests/if.test:
	* tests/incr.test:
	* tests/while.test:
	Report compilation errors at runtime, [Patch 1033689] by dgp.

2004-09-23  Mo DeJong  <[email protected]>

	* unix/dltest/Makefile.in (clean): Fixup make clean
	rule so that it does not delete all files when
	SHLIB_SUFFIX is set to the empty string in a static build.
	[Bug 1016726]

2004-09-23  Don Porter	<[email protected]>

	* generic/tclBasic.c:	Corrections to the 2004-09-21 commit
	* generic/tclExecute.c:	regarding ERR_ALREADY_LOGGED.  That commit
	* generic/tclNamesp.c:	caused Tk test send-10.7 to fail.  Added
	* tests/namespace.test (25.7,8):	tests in the Tcl test suite
	* tests/pkg.test (2.25,26):	to catch this error without the
	aid of Tk in the future.

	* generic/tclCmdAH.c (Tcl_ExprObjCmd):	Simplified the TclObjCmdProc
	of [expr] with a call to Tcl_ConcatObj.

2004-09-22  Don Porter	<[email protected]>

	* generic/tclCmdMZ.c (TclProcessReturn):	Support the -errorline
	* generic/tclCompile.c (TclCompileScript):	option to [return].
	* tests/compile.test (16.23.*):	Use that capability to defer reporting
	* tests/misc.test (1.2):	of parse errors until runtime.
	Updated tests to reflect change. [Bug 1032805]

	* library/tzdata/America/Montevideo: Updated to reflect
	ftp://elsie.nci.nih.gov/pub/tzdata2004d.tar.gz. (Changes
	to Asia/Jerusalem were in the comments only.) [Routine
	maintenance - no bug] Spanish-language description of the
	change at http://www.presidencia.gub.uy/decretos/2004091502.htm

2004-09-21  Don Porter	<[email protected]>

	* generic/tclCompCmds.c:	Tolerate [append] syntax errors
	* tests/appendComp.test (8.1):	at compile time, and allow runtime
	to raise the error (or succeed if a redefined [append] allows).

	* generic/tclBasic.c:	Reworked management of the interp
	* generic/tclCompile.c:	flag ERR_ALREADY_LOGGED, to reduce
	* generic/tclExecute.c: its exposure.  Still left several
	* generic/tclNamesp.c:	references that are just too nice
	on performace to do away with.	These changes also resolve
	an inconsistency in the ::errorInfo values produced by
	[namespace eval x error foo bar] and
	[namespace eval x {error foo bar}].

	* generic/tclExecute.c (TclCompEvalObj):	Simplified
	the TclCompEvalObj routine.  Much housekeeping now reliably
	happens elsewhere.  [Patch 1031949]

2004-09-21  Donal K. Fellows  <[email protected]>

	* doc/interp.n: Tighten up wording on how [interp eval] and
	[interp invokehidden] operate w.r.t. stack frames. [Bug 926590]

2004-09-20  Don Porter	<[email protected]>

	* tests/error.test (error-6.2,3):	Added more tests to verify
	::errorCode setting by/after a [catch].

2004-09-19  Miguel Sofer <[email protected]>

	* generic/tclCmdAH.c: removed outdated comment [Bug 1029518].

	* generic/tclExecute.c (TEBC-INST_LSHIFT,INST_RSHIFT): Ensure that
	large shifts end up shifting correctly. [Bug 868467]

	* doc/FileSystem.3, doc/OpenFileChnl.3: More documentation fixes
	from Mikhail Kolesnitchenko. [Patch 1022527]
	* doc/*: Standardize highlighting of symbols defined in tcl.h

2004-09-17  Don Porter	<[email protected]>

	* generic/tclBasic.c (Tcl_AddObjErrorInfo, Tcl_LogCommandInfo):
	* generic/tclCmdAH.c ([catch], [error]):
	* generic/tclCmdMZ.c ([return]):
	* generic/tclProc.c (TclUpdateReturnInfo):
	* generic/tclResult.c (Tcl_SetErrorCodeVA, Tcl_SetObjErrorCode)
	(TclTransferResult):	Refactored so that all errorCode setting
	flows through Tcl_SetObjErrorCode().  This greatly reduces the
	number of different places in the code that need to know details
	about an internal bitflag field of the Interp struct.  Also
	places errorCode setting in one place for easier future mods.

2004-09-17  Kevin B.Kenny  <[email protected]>

	* generic/tclDate.c:	Revised tclGetDate.y to use bison instead
	* generic/tclGetDate.y: of yacc to build the parser, eliminating
	* generic/tclInt.h:	all the complicated hackery involving
	* unix/Makefile.in:	'sed' postprocessing.  Rebuilt the parser.

2004-09-14  Kevin B. Kenny  <[email protected]>

	* generic/tclClock.c (ClockOldscanObjCmd): Silenced a compiler
	warning (long passed as a param where unsigend long was
	expected).  'Unsigned long' is wrong, but the fix is really
	to change the signature of TclGetDate to return a structure of
	its 'yy' variables and then do the remaining work inside
	clock.tcl. But, as I said on 2004-09-08, that's a job for
	another day.  [Bug 1027993]

2004-09-10  Miguel Sofer <[email protected]>

	* doc/interp.n:
	* generic/tclInterp.c (TclPreventAliasLoop, AliasCreate):
	* tests/interp.test (17.4-6, 19.3-4): fixing problems with
	renaming of aliases [Bugs 707104 1026493]. Fix designed by dgp.

2004-09-13  Donal K. Fellows  <[email protected]>

	* generic/tclNamesp.c (NsEnsembleImplementationCmd): Add token
	field to internal rep of EnsembleCmdRep structure so that we can
	check it to see if the subcommand object is really being used with
	the same ensemble. [Bug 1026903]

2004-09-10  Andreas Kupries  <[email protected]>

	* generic/tcl.h: Micro formatting fixes.
	* generic/tclIOGT.c: Channel version fixed, must be 3, to have
	  wideseekProc. Thanks to David Graveraux <[email protected]>.

2004-09-11  Don Porter	<[email protected]>

	* generic/tclNamespace.c (TclGetNamespaceForQualName):	Resolved
	longstanding inconsistency in the treatment of the TCL_NAMESPACE_ONLY
	flag revealed by testing the 2004-09-09 commits against Itcl.
	TCL_NAMESPACE_ONLY now acts as specified in the pre-function
	comment, forcing resolution in the passed in context namespace.
	It has been incorrectly forcing resolution in the interp's current
	namespace.

2004-09-10  Kevin Kenny	 <[email protected]>

	* library/clock.tcl: Fixed a bug where %z always put a plus
	sign on the time zone in :localtime.
	* tests/clock.test: Added test case for the above bug.

2004-09-10  Miguel Sofer <[email protected]>

	* generic/tclExecute.c (INST_CONCAT1): added a peephole
	optimisation for concatting an empty string. This enables
	replacing the idiom 'K $x [set x {}]' by '$x[set x {}]' for
	fastest execution.

2004-09-09  David Gravereaux <[email protected]>

	* win/tclWinConsole.c: Calls to WriteFile and WriteConsoleA
	changed to WriteConsole for simplicity.

2004-09-09  Don Porter	<[email protected]>

	* generic/tclNamesp.c (Tcl_ForgetImport):	Corrected faulty
	* tests/namespace.test:	logic that relied exclusively on string
	matching and failed in the presence of [rename]s.  [Bug 560297]
	Also corrected faulty prevention of [namespace import] cycles.
	[Bug 1017299]

2004-09-08  Don Porter	<[email protected]>

	* generic/tclBasic.c (Tcl_CreateInterp):	Removed obsolete
	field for storing the string-based command procedure of built-in
	commands.  We no longer have any string-based built-in commands!

2004-09-08  Kevin B. Kenny <[email protected]>

	clock-34.* test cases so that the consistency check is performed
	in :localtime rather than the current time zone.  This change
	allows dealing with issues where the C library has a different
	idea of DST conversion than Tcl. (Real fix would be to break
	TclGetDate into separate parser and time converter, and do
	the time conversion in clock.tcl. That's for another day.)
	Added regression test case for the bug where month was scanned
	incorrectly in -timezone :localtime. [Bug 1023779] Added
	regression test case for %k at the zero hour.

2004-09-07  David Gravereaux <[email protected]>

	* win/makefile.vc: some quoting needed to be removed as it was
	breaking with VC7. [Bug 1023150]

	its imports.  [Bug 1016167]
	* library/clock.tcl (InitTZData, ClearCaches): Changed so that the
	in-memory time zone :UTC (and its aliases) always gets
	reinitialised, in case tzdata is absent. [Bug 1019537, 1023779]
	* library/tzdata/*: Regenerated.
	* tests/clock.test (clock-31.*, clock-39.1): Corrected a problem
	where the 'system' locale tests fail on a non-English Windows
	machine. [Bug 1023761].	 Added a test to make sure that alias
	time zones load correctly. [Bug 1023779].
	* tests/timer.test (timer-1.1, timer-2.1): Changed to (one hopes!)
	be more resilient on an overloaded system, if [after 200] sleeps
	for 300 ms or longer.
	* tools/tclZIC.tcl (writeLinks): Corrected a problem where
	alias time zone names were written incorrectly, causing them
	to fail to load at run time. [Bug 1023779].

	* doc/lsearch.n: Clarified meaning of -dictionary. [Bug 759545]

2004-09-02  Vince Darley  <[email protected]>

	* win/makefile.vc: clock.tcl needs to be installed.

2004-09-01  Jeff Hobbs	<[email protected]>

	* win/tclWinReg.c (BroadcastValue): WIN64 cast corrections

	* win/tclWinDde.c (DdeClientWindowProc):
	(DdeServicesOnAck, DdeEnumWindowsCallback): WIN64 corrections

	* win/tclWin32Dll.c (TclWinCPUID): need _asm for WIN64 (Itanium),
	until we have it, just return unknown. [Bug 1020445]

2004-09-01  Donal K. Fellows  <[email protected]>

	* doc/regsub.n, doc/RegConfig.3, doc/Environment.3:
	* doc/CrtChannel.3, doc/safe.n: Use correct abbreviations.

2004-08-31  Donal K. Fellows  <[email protected]>

	* doc/format.n, doc/file.n, doc/exec.n, doc/dde.n, doc/clock.n:
	* doc/catch.n, doc/binary.n: More spelling and grammar fixes from
	Mikhail Kolesnitchenko. [Patch 1018486]

2004-08-31  Vince Darley  <[email protected]>

	* doc/FileSystem.3:
	* generic/tclIOUtil.c: Clarified documentation regarding ability

	* unix/Makefile.in: added customization of default module path roots
	via TCL_MODULE_PATH makefile variable.
	* macosx/Makefile: add platform standard locations to default
	module path roots. [Patch 942881]

	* tests/env.test: macosx fixes.

2004-08-25  Don Porter	<[email protected]>

	* tests/timer.test (timer-10.1):	Test for Bug 1016167.
	* generic/tclTimer.c:	Workaround for situation when a
	[namespace import] causes the objv[0] value to be something
	other than what Tcl_AfterObjCmd expects.  [Bug 1016167].

2004-08-25  Donal K. Fellows  <[email protected]>

	* generic/tclNamesp.c (NsEnsembleImplementationCmd): Use the
	ensemble command token to get the name of the ensemble for passing
	to the -unknown handler instead of relying on objv[0], which may
	contain useless info in the presence of [namespace import].
	Problem found by Don Porter when investigating [Bug 1016167].

2004-08-24  Don Porter	<[email protected]>

	* generic/tclProc.c:		The routine TclProcInterpProc was a
	* generic/tclTestProcBodyObj.c:	specific instance of the general
	service already provided by TclObjInvokeProc.  Removed
	TclProcInterpProc and TclGetInterpProc from the code...

	* generic/tclInt.decls	...and from the internal stubs table.
	* generic/tclIntDecls.h
	* generic/tclStubInit.c

2004-08-24  Donal K. Fellows  <[email protected]>

	* doc/string.n: Added clarifying note.

2004-08-23  Don Porter	<[email protected]>

	* library/auto.tcl:	Updated [tcl_findLibrary] search path
	to include any [<pkg>::pkgconfig get scriptdir,runtime] directory,
	as well as the $::auto_path.  [RFE 695441]

2004-08-21  Kevin B. Kenny  <[email protected]>

	* tests/clock.test (clock-38.1): Changed TZ setting to specify
	CET in excruciating detail to deal with systems that lack the
	Posix defaults for DST changes (and to be formally correct with
	the change dates for CET).

2004-08-19  Donal K. Fellows  <[email protected]>

	* generic/tclScan.c (Tcl_ScanObjCmd, ValidateFormat): Ensure that
	the %ld conversion works correctly on 64-bit platforms. [Bug 1011860]

2004-08-19  Kevin Kenny	 <[email protected]>

	* library/clock.tcl (format): Changed default timezone format
	from alphabetic to numeric to produce scannable times in more
	locales.
	* tests/clock.test (clock-37.1): Removed now-unused 'needPST'
	constraint and the comments that refer to it.

	* doc/tm.n: New file, documentation for Tcl Modules, based on the
	  TIP.

	* unix/mkLinks: Regenerated.
	* win/makefile.vc: Added tm.tcl to list of files to install.

2004-08-18  Kevin Kenny	 <[email protected]>

	* tests/httpd (httpdRespond): Corrected an abuse of the [clock]
	command that caused test failures for some values of [clock clicks].

	* doc/clock.n

2004-08-13  Don Porter	<[email protected]>

	* library/msgcat/msgcat.tcl:	Added checks to prevent [mclocale]
	* tests/msgcat.test:	from registering filesystem paths to possibly
	malicious code to be evaluated by a later [mcload].

2004-08-10  Zoran Vasiljevic <[email protected]>

	* unix/tclUnixThrd.c (TclpThreadCreate): changed handling of
	the returned thread ID since broken on 64-bit systems (Cray).
	Thanks to Rob Ratcliff for reporting the bug.

2004-08-03  Donal K. Fellows  <[email protected]>

	* generic/tclNamesp.c (MakeCachedEnsembleCommand): Initialize the
	epoch field cached in the subcommand. [Bug 989298]
	(NsEnsembleImplementationCmd): Plug a leak (thanks to Miguel Sofer
	for spotting it with valgrind) and reduce the number of goto
	labels to make the code clearer.

2004-08-02  Don Porter	<[email protected]>

	* library/package.tcl (pkg_mkIndex):	Updated [pkg_mkIndex] to
	make use of [glob -directory $dir -tails] and return options.

	TIP#207 IMPLEMENTATION

	* doc/interp.n:		Added support for a -namespace option to the
	* generic/tclBasic.c:	[interp invokehidden] command.	Also added an
	* generic/tclInt.h:	internal routine TclObjInvokeNamespace() and
	* generic/tclInterp.c:	corrected the flag names TCL_FIND_ONLY_NS and
	* generic/tclNamesp.c:	TCL_CREATE_NS_IF_UNKNOWN that are passed to the
	* generic/tclTrace.c:	internal routine TclGetNamespaceForQualName().
	* tests/interp.test:	[Patch 981841]

	* generic/tclLiteral.c (TclCleanupLiteralTable):	Corrected
	* tests/compile.test (compile-12.4):	flawed deletion of literal
	internal reps that could lead to accessing of freed memory.
	Thanks to Kevin Kenny for test case and fix [Bug 1001997].

2004-07-30  Don Porter	<[email protected]>

	* tests/safe.test (safe-2.1):  Disabled senseless test.	 [Bug 999612]

	* library/auto.tcl (auto_reset):  Removed "protected" list of commands
	from [auto_reset].  All entries in the auto_index can be re-loaded.
	* library/package.tcl: Updated comment to reflect 2004-07-28 commit.

	* generic/tclEvent.c (Tcl_Finalize):	Re-organized Tcl_Finalize
	so that Tcl_ExitProc's that call Tcl_Finalize recursively do not
	cause deadlock.	 [Patch 999084 fixes Tk Bug 714956]

2004-07-30  Daniel Steffen  <[email protected]>

	* unix/configure:
	* unix/tcl.m4 (SC_CONFIG_CFLAGS): Darwin: instead of setting PLAT_OBJS
	to explict object files in tcl.m4, refer to MAC_OSX_OBJS makefile var.
	* unix/Makefile.in: added MAC_OSX_OBJS variable.

2004-07-29  Don Porter	<[email protected]>

	* library/package.tcl:	[::pkg::create] is now an alias.  Test
	safe-2.1 will now fail until Bug 999612 is corrected.

2004-07-28  Don Porter	<[email protected]>

	* library/package.tcl:		Moved private command
	* library/tclIndex:		[pkg_compareExtension] into ::tcl::Pkg.
	* tests/pkg_mkIndex.test:	Also moved implementation of
	[::pkg::create] to [::tcl::Pkg::Create].

2004-07-25  Pat Thoyts	<[email protected]>

	* tests/io.test: Make io-61.1 create file as binary to pass on Win32

2004-07-23  Miguel Sofer <[email protected]>

	* generic/tclVar.c: simplify tclLocalVarNameType, removing the
	reference to the corresponding proc. The reference is now seen as
	unnecessary, and it may cause leaking circular references under
	some circumstances (see for example [Bug 994838]).

2004-07-22  Don Porter	<[email protected]>

	* tests/eofchar.data (removed): Test io-61.1 now generates its own
	* tests/io.test:	file of test data as needed.

2004-07-20  Jeff Hobbs	<[email protected]>

	* generic/tclEvent.c:	    Correct threaded obj allocator to
	* generic/tclInt.h:	    fully cleanup on exit and allow for
	* generic/tclThreadAlloc.c: reinitialization. [Bug #736426]
	* unix/tclUnixThrd.c:	    (mistachkin, kenny)
	* win/tclWinThrd.c:

2004-07-21  Kevin Kenny	 <[email protected]>

	* generic/tclBasic.c (DeleteInterpProc):
	* generic/tclLiteral.c (TclCleanupLiteralTable):
	* generic/tclInt.h: added a TclCleanupLiteralTable function,
	called from DeleteInterpProc, that frees internal representations
	of shared literals early when an interpreter is being deleted.
	This change corrects a number of memory mismanagement issues in
	the cases where the internal representation of one literal
	contains a reference to another, and avoids conditions such as
	resolved variable names referring to procedure and namespace
	contexts that no longer exist.	[Bug 994838]

2004-07-20  Daniel Steffen  <[email protected]>

	* unix/Makefile.in:
	* win/Makefile.in: added 'install-private-headers' makefile target
	to allow optionally installing private tcl headers. [FR 922727]

	* macosx/Makefile: use new 'install-private-headers' target
	to install private headers into framework. [FR 922727]

	* unix/tclUnixFile.c (NativeMatchType): added support for
	readonly matching of user immutable files (where available).

	* macosx/tclMacOSXBundle.c: dynamically acquire address for
	CFBundleOpenBundleResourceMap symbol, since it is only present in
	full CoreFoundation on Mac OS X and not in CFLite on pure Darwin.

2004-07-19  Zoran Vasiljevic <[email protected]>

	* win/tclwinThrd.c: redefined MASTER_LOCK to call
	TclpMasterLock. Fixes Bug #987967

2004-07-17  Vince Darley  <[email protected]>

	* generic/tclIOUtil.c: fix to rare 'cd' infinite loop in
	normalization with vfs [Bug 991420].
	* tests/fileSystem.test: added test for above bug.

	* doc/FileSystem.3: clarified documentation of posix error
	codes in 'remove directory' FS proc - 'EEXIST' is used to
	signify a non-empty directory error (bug reported against
	tclvfs).

2004-07-16  Jeff Hobbs	<[email protected]>

	* unix/Makefile.in, unix/tcl.m4:     move (C|LD)FLAGS after their
	* unix/configure.in, unix/configure: _DEFAULT to allow for env
	setting to override m4 switches.  Move SC_MISSING_POSIX_HEADERS up
	and consolidate calls to limit redundancy in configure.
	(CFLAGS_WARNING): Remove -Wconversion
	(SC_ENABLE_THREADS): Set m4 to force threaded build when built

	* unix/tclUnixThrd.c (TclpFinalizeMutex): Accepted Joe
	  Mistachkin's patch for [Tcl SF Bug 990453], closing leakage of
	  mutexes. They were not destroyed properly upon finalization.

2004-07-15  Andreas Kupries  <[email protected]>

	* generic/tclIO.h (CHANNEL_INCLOSE):	   New flag. Set in
	* generic/tclIO.c (Tcl_UnregisterChannel): 'Tcl_Close' while the
	* generic/tclIO.c (Tcl_Close):		   close callbacks are
	  run. Checked in 'Tcl_Close' and 'Tcl_Unregister' to prevent
	  recursive call of 'close' in the close-callbacks. This is a
	  possible error made by implementors of virtual filesystems based
	  on 'tclvfs', thinking that they have to close the channel in the
	  close handler for the filesystem.

2004-07-14  Andreas Kupries  <[email protected]>

	  <[email protected]>.

2004-07-15  Zoran Vasiljevic <[email protected]>

	* generic/tclEvent.c (Tcl_Finalize): stuffed memory leak
	incurred by re-initializing of TSD slots after the last call to
	TclFinalizeThreadData (done from within Tcl_FinalizeThread()).
	We basically just repeat the TclFinalizeThreadData() once more
	before tearing down TSD keys in TclFinalizeSynchronization().
	There should be more elaborate mechanism in place for handling
	such issues, based on thread cleanup handlers registered on the
	OS level. Such change requires much more work and would also
	require TIP because some visible parts of Tcl API would have to
	be modified. In the meantime, this will do.

	* generic/tclNotify.c (TclFinalizeNotifier): Added conditional
	notifier finalization based on the fact that an TclInitNotifier
	has been called for the current thread. This fixes the Tcl
	Bug #770053 again. Hopefully this time w/o unwanted side-effects.

2004-07-15  Kevin Kenny	 <[email protected]>

	* generic/tclLiteral.c (TclReleaseLiteral): Removed unused
	variable 'codePtr' to silence a message from VC++.

2004-07-15  Miguel Sofer <[email protected]>

	* generic/tclCompile.c (TclCompileScript):
	* generic/tclLiteral.c (TclReleaseLiteral): fix for [Bug 467523],
	which resurfaced with the latest changes. The previous strategy
	was to have special code in TclReleaseLiteral to handle the
	self-references generated by empty scripts. The new approach
	avoids the self-reference altogether, by having empty scripts
	return an unshared literal.

	* generic/tclNamesp.c (BuildEnsembleConfig): Don't forget to clean
	out references when deleting the hash table.
	* generic/tclDictObj.c (Tcl_DictObjRemoveKeyList): Oops, forgot to
	delete value object when removing the hash entry. [Bug 989093 in part]

2004-07-11  Miguel Sofer <[email protected]>

	* generic/tclExecute.c (TEBC): fixed leak of expandNestList objs
	when there is an error while an expansion is in progress (code
	added at checkForCatch).

2004-07-11  Vince Darley  <[email protected]>

	* generic/tclIOUtil.c: fix to 'cd' bug when vfs is active
	[Bug 986944 in tclvfs project] - this bug recently introduced
	by some threading fixes.  Need to work out how to add
	tests for this.

2004-07-10  Kevin Kenny	 <[email protected]>

	* tests/clock.test (clock-2.11): Changed the test so that
	it isn't an infinite loop when run under valgrind on a slow
	virtual machine.  Thanks to Miguel Sofer for the bug report.
	Also put in code to restore env(LC_TIME) after tests complete,
	silencing a warning from 'make TESTFLAGS="-debug 1" test'.

2004-07-08  Miguel Sofer <[email protected]>

	* generic/tclBasic.c (DeleteInterpProc): reverted the modification
	of 3 days ago, as the leak of [Bug 983660] is now handled by the
	change in TclCleanupByteCode.
	* generic/tclCompile.c (TclCleanupByteCode): let each bytecode
	remove its references to literals at interp deletion, without
	updating the dying literal table.
	* generic/tclLiteral.c (TclDeleteLiteralTable): with the above
	change to TclCleanupByteCode, this function now removes a single
	reference to the literal object and cleans up its own structures.

2004-07-08  Kevin Kenny	 <[email protected]>

	* win/tclWinInit.c (AppendEnvironment): Silenced a compilation
	warning about a type mismatch.

2004-07-07  Miguel Sofer <[email protected]>

	* generic/tclCompile.c (TclCompileScript): fix for [Bug 458361].
	Single-word scripts are compiled with an unshared cmdName to avoid
	shimmering between bytecode and cmdName reps.

2004-07-07  Don Porter	<[email protected]>

	* generic/tclCmdMZ.c (TclMergeReturnOptions):  Simplified logic and
	removed potential memory leak.	[Bug 986257].

2004-07-07  Donal K. Fellows  <[email protected]>

	* tools/man2help2.tcl (setTabs, IPmacro): Added support for the
	more advanced *roff macros used in Tk's doc/bind.n

	* generic/tclObj.c (TclInitObjSubsystem): Declare all current
	object types.

2004-07-06  Don Porter	<[email protected]>

	* tests/cmdMZ.test (cmdMZ-return-2.17):	 Added a test that a word
	containing backslash-quoted value is treated correctly.

	* generic/tclCompile.c (TclWordKnownAtCompileTime):  [Bug 986196]
	Corrected flaw above and the flaw that caused TCL_TOKEN_SIMPLE_WORDs
	to have their original word value copied ( "{a b}" ) rather than the
	actual value ( "a b" ).	 Thanks to Kevin Kenny for report and tests.

2004-07-06  Kevin B. Kenny  <[email protected]>

	* tests/cmdMZ.test (cmdMZ-return-2.15,cmdMZ-return-2.16):
	Added a test that a return code containing spaces is correctly
	returned.

2004-07-06  Donal K. Fellows  <[email protected]>

	* tools/man2html2.tcl (IPmacro, setTabs): Added support for the
	more advanced *roff macros used in Tk's doc/bind.n

2004-07-05  Miguel Sofer <[email protected]>

	* generic/tclBasic.c (DeleteInterpProc): fix for [Bug 983660],
	found by pspjuth. Tear down the global namespace before freeing
	the interp handle, to allow the bytecodes to free their non-shared
	literals.
	* generic/tclLiteral.c (TclReleaseLiteral): moved special code for
	self-ref so that it is also used for non-shared literals. Possible
	bug found by inspection.

2004-07-03  Miguel Sofer <[email protected]et>

	* generic/tclExecute.c (ExprRoundFunc):
	* tests/expr-old.test (39.1): added support for wide integers to
	round(); [Bug 908375], reported by Hemang Lavana.

2004-07-03  Miguel Sofer <[email protected]>

	* generic/tclCompile.h:
	* generic/tclInt.decls:
	* generic/tclIntDecls.h:
	* generic/tclStubInit.c: Moved declaration of TclCompEvalObj()
	from tclCompile.h to the internal stubs table, for compiler
	experimentation.

2004-07-02  Jeff Hobbs	<[email protected]>

	* generic/regcomp.c (stid): correct minor pointer size error

	* generic/tclPipe.c (TclCreatePipeline): applied TIP #202 patch
	* doc/exec.n, tests/exec.test:		 that adds 2>@1 as a
	special case redirection of stderr to the result output.

2004-07-02  Kevin B. Kenny  <[email protected]>

	* tests/io.test: Changed several tests to run the event
	loop rather than just calling [update] periodically, avoiding
	intermittent failures (usually in io-29.32) that stemmed from
	unreaped processes on Windows.
	* tests/winPipe.test (winpipe-1.11): Fixed a bug that caused
	test to fail if the path name of the working directory contained
	whitespace [Bug 678430]

2004-07-01  Vince Darley  <[email protected]>

	* tests/fileSystem.test: Added test for [Bug 970529]

2004-07-01  Donal K. Fellows  <[email protected]>

	* win/README.binary, win/README: Updated references to Tcl and Tk
	8.4 to point to 8.5 instead.  Thanks to Theo Verelst for spotting
	this.
	* generic/tcl.h: Added note to help prevent those changes from
	getting missed in the future.

	* doc/Namespace.3, doc/load.n, doc/Limit.3: Typo fixes and remove
	duplicate documentation. [Bug 983146]

2004-06-30  Don Porter	<[email protected]>

	* tests/fileSystem.test: Minor correction to new fileSystem-9.X
	tests so that they clean up temporary directories correctly.

2004-06-30  Vince Darley  <[email protected]>

	* doc/filename.n: clarified behaviour concerning trailing
	slashes in filenames [Bug 971976]

	* win/tclWinFile.c:
	* tests/fileSystem.test: fix and tests for [Bug 979879]

2004-06-30  Donal K. Fellows  <[email protected]>

	TIP#188 IMPLEMENTATION

	* doc/string.n, tests/string.test:	 Add 'wideinteger' to things
	* generic/tclCmdMZ.c (Tcl_StringObjCmd): that can be tested for with
	the [string is] subcommand. [Patch 940915, by Kevin Kenny]

2004-06-29  Don Porter	<[email protected]>

	* win/tclWinInit.c:	Corrected reference counting flaw in
	recent changes.	 Thanks to Pat Thoyts. [Bug 981893].

2004-06-29  Vince Darley  <[email protected]>

	* win/tclWin32Dll.c: fix to compilation with VC++ 5.2

2004-06-29  Donal K. Fellows  <[email protected]>

	* library/safe.tcl: Make sure that the temporary variable is
	local to the namespace and not inadvertently global. [Bug 981733]

2004-06-24  Donal K. Fellows  <[email protected]>

	* tests/unixNotfy.test: Modified constraints so that testing with
	a threaded tclsh (not tcltest) will not hang.

2004-06-23  Don Porter	<[email protected]>

	* generic/tclThreadStorage.c:	Corrected type casting errors that led
	to calculation of a negative index value, thus accesses outside the
	threadStorageCache array, thus memory corruption.  Crash observed on
	Mac OS X platform.

2004-06-23  Joe Mistachkin  <[email protected]>

	* unix/tcl.m4:
	* win/makefile.vc:
	* win/rules.vc:
	* win/Makefile.in: Modified the unix, VC++, and Cygwin build systems
	* win/configure: to include the new "tclThreadStorage.c" and the new
	* win/tcl.m4: USE_THREAD_STORAGE define.

2004-06-23  Pat Thoyts	<[email protected]>

	* tests/io.test: Added -force to 18.1 and 18.2. This was failing
	on WinXP.

	* tests/winFCmd.test: Added a cleanup to winFCmd-16.11 to avoid a
	failure in 16.12.

	winDde-4.2, -6.5, and -6.6 appear to be much less frequent.
	[Bug #957449]

2004-06-23  Donal K. Fellows  <[email protected]>

	* tests/*.test: Standardize use of platform constraints.

	* unix/tclUnixInit.c (GetStackSize, TclpCheckStackSpace):
	* unix/tclUnixThrd.c (TclpThreadGetStackSize): Added code to check
	whether the C stack is about to be exceeded, from [Patch 746378]
	by Joe Mistachkin but with substantial revisions.

2004-06-22  Kevin Kenny	 <[email protected]>

	* generic/tclEvent.c (NewThreadProc): Fixed broken build on
	Windows caused by missing TCL_THREAD_CREATE_RETURN.

	* tests/stack.test (stack-3.1): Corrected nuisance error in
	threaded builds.

2004-06-21  Donal K. Fellows  <[email protected]>

	* generic/tclThreadAlloc.c (Ptr2Block): Rewrote so as to maximize
	the chance of detecting and reporting a memory inconsistency without
	relying on things being consistent. [Bug 975895]

2004-06-18  Don Porter	<[email protected]>

	* tests/load.test:	Relaxed strictness of error message matching
	for test load-2.3 so that it will pass on Mac OSX.

	* generic/tclEncoding.c: Static TclFindEncodings -> FindEncodings.
	* generic/tclInt.h:	Updated TclpFindExecutable() so that failed
	* generic/tclUtil.c:	attempts to find the executable are saved

	* unix/configure: autoconf-2.57

2004-06-18  Donal K. Fellows  <[email protected]>

	* unix/tclUnixInit.c (localeTable): Added some more locale to
	encoding mapping info from Jim Huang <[email protected]>

	* generic/tclInt.h (PendingObjData,TclFreeObjMacro,etc):
	* generic/tclObj.c (TclFreeObj): Added scheme for making TclFreeObj()
	avoid blowing up the C stack when freeing up very large object
	trees. [Bug 886231]

	* win/tclWinInit.c (SetDefaultLibraryDir): Fix logic, simplify and
	add comments.

2004-06-17  Don Porter	<[email protected]>

	* generic/tclObj.c:	Added missing space in panic message.

	* win/tclWinInit.c:	Inform [tclInit] about the default library
	directory via the ::tclDefaultLibrary variable.	 This should correct
	a problem with my 2004-06-11 commit.  Better solutions still in the
	works.	Thanks to Joe Mistachkin for pointing out the breakage.

2004-06-16  Don Porter	<[email protected]>

	* doc/library.n:	Moved variables ::auto_oldpath and
	* library/auto.tcl:	::unknown_pending into ::tcl namespace.
	* library/init.tcl:	[Bugs 808319, 948794]

2004-06-15  Donal K. Fellows  <[email protected]>

	* doc/binary.n: Added some notes to the documentation of the 'a'
	format to address the point raised in [RFE 768852].

2004-06-15  Jeff Hobbs	<[email protected]>

	* unix/tclConfig.sh.in (TCL_EXTRA_CFLAGS): set to @[email protected], which
	is the configure-time CFLAGS. Addendum to m4 change on 2004-05-26.

2004-06-14  Kevin Kenny	 <[email protected]>

	* win/Makefile.in: Corrected compilation flags for tclPkgConfig.c
	so that it doesn't require Stubs.
	* generic/tclBasic.c (Tcl_CreateInterp): Removed comment stating
	that TclInitEmbeddedConfigurationInformation needs Stubs; with the
	change above, the comment is now erroneous.

2004-06-11  Don Porter	<[email protected]>

	* doc/Encoding.3:	Removed bogus claims about tcl_libPath.

	* generic/tclInterp.c (Tcl_Init):	Stopped setting the
	tcl_libPath variable.  [tclInit] can get all its directories
	without it.

	* win/configure.in:

	* generic/tclBasic.c (Tcl_CreateInterp): Moved call to
	TclInitEmbeddedConfigurationInformation() earlier in
	Tcl_CreateInterp() so that other parts of interp creation
	and initialization may access and use the config values.

2004-06-11  Kevin Kenny	 <[email protected]>

	* win/tclAppInit.c: Restored the 'setargv' procedure when
	compiling with mingw.  Apparently, the command line parsing in
	mingw doesn't work as well as that in vc++, and the result was
	(1) that winPipe-8.19 failed, and (2) that 'make test' would
	work at all only with TESTFLAGS='-singleproc 1'. [Bug 967195]

2004-06-10  Zoran Vasiljevic <[email protected]>

	* generic/tclIOUtil.c: removed forceful setting of the
	  private cached current working directory rep from
	  within the Tcl_FSChdir(). We delegate this task to
	  the Tcl_FSGetCwd() which does this task anyway.
	  The relevant code is still present but disabled
	  temporarily until the change proves correct. The Tcl
	  test suite passes all test with the given change so
	  I suppose it is good enough.

2004-06-10  Don Porter	<[email protected]>

	* unix/tclUnixInit.c (TclpInitLibraryPath):	Disabled addition of
	* win/tclWinInit.c (TclpInitLibraryPath):	relative-to-executable
	directories to the library search path.	 A first step in reform of
	Tcl's startup process.

	***POTENTIAL INCOMPATIBILITY***
	Attempts to directly run ./tclsh or ./tcltest out of a build
	directory will either fail, or will make use of an installed
	script library in preference to the one in the source tree.
	Use `make shell` or `make runtest` instead.

	* tests/unixInit.test:	Modified tests to suit above changes.

	* generic/tclPathObj.c:	Corrected [file tail] results when operating
	on a path produced by TclNewFSPathObj(). [Bug 970529]

2004-06-09  Zoran Vasiljevic <[email protected]>

	* generic/tclIOUtil.c: partially corrected [Bug 932314].
	  Also, corrected return values of Tcl_FSChdir() to
	  reflect those of the underlying platform-specific call.
	  Originally, return codes were mixed with those of Tcl.

2004-06-08  Miguel Sofer <[email protected]>

	* generic/tclCompile.c:
	* generic/tclExecute.c: handle warning [Bug 969066]

2004-06-08  Donal K. Fellows  <[email protected]>

	* generic/tclHash.c (RebuildTable): Move declaration of variable
	so it is only declared when it is used. [Bug 969068]

	* generic/tclInt.decls:			clock frequency in
	* generic/tclIntDecls.h:		Tcl_WinTime
	* generic/tclIntPlatDecls.h:		so that any clock frequency
	* generic/tclPlatDecls.h:		is accepted provided that
	* generic/tclStubInit.c:		all CPU's in the system share
	* tests/platform.test (platform-1.3):	a common chip, and hence,
	* win/tclWin32Dll.c (TclWinCPUID):	presumably, a common clock.
	* win/tclWinTest.c (TestwincpuidCmd)	This change necessitated a
	* win/tclWinTime.c (Tcl_GetTime):	small burst of assembly code
	to read CPU ID information, which was added as TclWinCPUID in the
	internal Stubs.	 To test this code in the common case of a
	single-processor machine, a 'testwincpuid' command was added to
	tclWinTest.c, and a test case in platform.test.	 Thanks to Jeff
	Godfrey and Richard Suchenwirth for reporting this bug. [Bug
	#976722]

2004-06-04  Don Porter	<[email protected]>

	* generic/tcl.h:	Restored #include <stdio.h> to tcl.h,
	rejecting the "fix" for "Bug" 945570.  Tcl_FSSeek() needs the
	values of SEEK_SET, etc. and too many extensions rely on tcl.h
	providing stdio.h for them.

2004-06-02  Jeff Hobbs	<[email protected]>

	* win/tclWinFile.c (TclpFindExecutable): when using
	GetModuleFileNameA (Win9x), convert from CP_ACP to WCHAR then
	convert back to utf8.  Adjunct to 2004-04-07 fix.

2004-06-02  David Gravereaux <[email protected]>

	* tests/winPipe.test (winpipe-6.1): blocking set to 1 before
	closing to ensure we get an exitcode.  The windows pipe channel
	driver doesn't differentiate between a blocking and non-blocking
	close just yet, but will soon.	Part of [Bug 947693]

2004-06-02  Vince Darley  <[email protected]>

	* doc/file.n: fix to documentation of 'file volumes' (Bug 962435)

2004-06-01  David Gravereaux <[email protected]>

	each function in the limit implementation and rewrote the names of
	some non-public functions for greater clarity of purpose.
	* doc/interp.n: Added note about what happens when a limited
	interpreter creates a slave interpreter.
	* doc/Limit.3: Added manual page for the resource limit
	subsystem's C API. [Bug 953903]

2004-05-29  Joe English	 <[email protected]>

	* doc/global.n, doc/interp.n, doc/lrange.n:
	Fix minor markup errors.

2004-05-28  Donal K. Fellows  <[email protected]>

	* doc/*.n: Added examples to many (too many to list) more man pages.

	* generic/tclCmdMZ.c (Tcl_StringObjCmd):	uses are performed.

	The overall effect is to make building with gcc with the
	additional flags -Wstrict-prototypes -Wmissing-prototypes produce
	no increase in the total number of warnings (except for main(),
	which is undeclared for traditional reasons.)

2004-05-26  Jeff Hobbs	<[email protected]>

	* unix/Makefile.in:  Rework configure ordering to TCL_LINK_LIBS,
	* unix/tcl.m4:	     ENABLE_SHARED, CONFIG_CFLAGS, & ENABLE_SYMBOLS
	* unix/configure:    before TCL_EARLY_FLAGS and TCL_64BIT_FLAGS
	* unix/configure.in: (about 400 lines earlier) in configure.in.
	This forces CFLAGS configuration to be done before many tests,
	which is needed for 64-bit builds and may affect other builds.
	Also make CONFIG_CFLAGS append to CFLAGS directly instead of using
	EXTRA_CFLAGS, and have LDFLAGS append to any existing value.
	[Bug #874058]
	* unix/dltest/Makefile.in: change EXTRA_CFLAGS to DEFS

2004-05-26  Don Porter	<[email protected]>

	* library/tcltest/tcltest.tcl:	Correction to debug prints and testing
	* library/tcltest/pkgIndex.tcl:	if TCLTEST_OPTIONS value.  Corrected
	* tests/tcltest.test:		double increment of numTestFiles in
	-singleproc 1 configurations.  Updated tcltest-19.1 to tcltest 2.1
	behavior.  Corrected tcltest-25.3 to not falsely report a failure
	in tcltest.test.  Bumped to tcltest 2.2.6.  [Bugs 960560, 960926]

2004-05-25  Jeff Hobbs	<[email protected]>

	* doc/http.n (http::config): add -urlencoding option (default utf-8)
	* library/http/http.tcl:     that specifies encoding conversion of
	* library/http/pkgIndex.tcl: args for http::formatQuery.  Previously
	* tests/http.test:	     undefined, RFC 2718 says it should be
	utf-8. 'http::config -urlencoding {}' returns previous behavior,
	which will throw errors processing non-latin-1 chars.
	Bumped http package to 2.5.0.

2004-05-25  Donal K. Fellows  <[email protected]>

	* generic/tclInterp.c (DeleteScriptLimitCallback): Move all
	deletion of script callback hash table entries to happen here so
	the entries are correctly removed at the right time.  [Bug 960410]

2004-05-25  Miguel Sofer <[email protected]>

	* docs/global.n: added details for qualified variable names
	[Bug 959831]

2004-05-25  Miguel Sofer <[email protected]>

	* generic/tclNamesp.c (Tcl_FindNamespaceVar):
	* tests/namespace.test (namespace-17.10-12): reverted commit of
	2004-05-23 and removed the tests, as it interferes with the
	varname resolver and there are apps that break (AlphaTk). A fix
	will have to wait for Tcl9.

	* generic/tclVar.c: Caching of namespace variables disabled: no
	simple way was found to avoid interfering with the resolver's idea
	of variable existence. A cached varName may keep a variable's name
	in the namespace's hash table, which is the resolver's criterion
	for existence.

	* tests/namespace.c (namespace-17.10): testing for interference
	between varname caching and name resolver.

2004-05-25  Kevin Kenny	 <[email protected]>

	* tests/winFCmd.test: Correct test for the presence of a CD-ROM so
			      that it doesn't misdetect some other sort
			      of filesystem with a write-protected root as
			      being a CD-ROM drive. [Bug 918267]

2004-05-25  Don Porter	<[email protected]>

	* tests/winPipe.test:	Protect against path being set
	* tests/unixInit.test:	Unset path when done.
	* tests/unload.test (unload-3.1): Verify [pkgb_sub] does not exist.
	Delete interps when done.
	* tests/stringComp.test:	stop re-use of string.test test names
	* tests/regexpComp.test:	stop re-use of regexp.test test names
	* tests/namespace.test (namespace-46.3): Verify [p] does not exist.
	* tests/http.test:	Clear away the custom [bgerror] when done.

	* generic/tcl.h:      comments. [Bug 848440, second part]

	* tests/fCmd.test: Rewrote tests that failed consistently on NFS
	so they either succeed (through slightly more liberal matching of
	the results) or are constrained to not run. [Bug 931312]

	* doc/bgerror.n: Use idiomatic open flags for working with log
	files.	[Bug 959602]

2004-05-24  Jeff Hobbs	<[email protected]>

	* generic/tclExecute.c (VerifyExprObjType): use GET_WIDE_OR_INT to
	properly have tclIntType used for smaller values.  This corrects
	TclX bug 896727 and any other 3rd party extension that created
	math functions but was not yet WIDE_INT aware in them.

2004-05-24  Donal K. Fellows  <[email protected]>

	* generic/tclInterp.c (TclInitLimitSupport): Made limits work on
	platforms where sizeof(void*)!=sizeof(int). [Bug 959193]

2004-05-24 Miguel Sofer <[email protected]>

	* doc/set.n: accurate description of name resolution process,
	referring to namespace.n for details [Bug 959180]

2004-05-23  Miguel Sofer <[email protected]>

	* generic/tclNamesp.c (Tcl_FindNamespaceVar): [Bug 959052] fixed,
	insuring that no "zombie" variables are found.
	* generic/tclVar.c (TclLookupSimpleVar): comments re [Bug 736729]
	(predecessor of [Bug 959052]) removed.
	* tests/namespace.test: added tests 17.10-12

	The patch modifies non-documented behaviour, and passes every test
	in the testsuite. However, scripts relying on the old behaviour
	may break.
	Note that the only behaviour change concerns the creative writing
	of unset variables. More precisely, which variable will be created
	when neither a namespace variable nor a global variable by that
	name exists, as defined by [info vars]. The new behaviour is that
	the namespace resolution process deems a variable to exist exactly
	when [info vars] finds it - ie, either it has value, or else it
	was "fixed" by a call to [variable].
	Note: this patch was removed on 2002-05-25.

2004-05-22  Miguel Sofer <[email protected]>

	* generic/tclVar.c (TclObjLookupVar, TclObjUnsetVar2): fix for new
	(in tcl8.4) exteriorisations of [Bug 736729] due to the use of
	tclNsVarNameType obj types. Reenabling the use of this objType
	("VAR ref absolute" benchmark down to 66 ms, from 230).
	Added comments in TclLookupSimpleVar explaining my current
	understanding of [Bug 736729].

2004-05-22  Miguel Sofer <[email protected]>

	* generic/tclVar.c: fix for [Bug 735335]. The use of
	tclNsVarNameType objs is still disabled, pending resolution of
	[Bug 736729].

2004-05-21  Miguel Sofer <[email protected]>

	* tests/namespace.test (namespace-41.3): removed the {knownBug}
	constraint: [Bug 231259] is closed since nov 2001, and the fix of
	[Bug 729692] (INST_START_CMD) makes the test succeed.

2004-05-21  Donal K. Fellows  <[email protected]>

	* generic/tclExecute.c (TclExecuteByteCode): Move a few
	declarations a short distance so pre-C99 compilers can cope.  Also
	fix so TCL_COMPILE_DEBUG path compiles...

2004-05-21  Miguel Sofer <[email protected]>

	* generic/tclExecute.c (TclExecuteByteCode): reorganised TEBC
	automatic variables, defining them in tight blocks instead of at
	the function level. This has three purposes:
	- it simplifies the analysis of individual instructions
	- it is preliminary work to the non-recursive engine
	- it allows a better register allocation by the optimiser; under
	gcc3.3, this results in up to 10% runtime in some tests

2004-05-20  Donal K. Fellows  <[email protected]>

	* generic/tclInterp.c (TclLimitRemoveAllHandlers):
	* generic/tclBasic.c (DeleteInterpProc):
	* tests/interp.test (interp-34.7):
	Ensure that all limit callbacks are deleted when their interpreters
	are deleted. [Bug 956083]

2004-05-19  Kevin B. Kenny  <[email protected]>

	* win/tclWinFile.c (TclpMatchInDirectory): fix for an issue
	where there was a sneak path from Tcl_DStringFree to

	* generic/tclInterp.c (Tcl_LimitCheck): Fix the sense of checks to
	see whether a time limit has been extended.

	* tests/*.test: Many minor fixes, including ensuring that every
	test is run (so constraints control whether the test is doing
	anything) and making sure that constraints are always set using
	the API instead of poking around inside tcltest's internal
	datastructures.	 Also got rid of all trailing whitespace lines
	from the test suite!

2004-05-19  Andreas Kupries  <[email protected]>

	* generic/tclIO.c: Fixed [SF Tcl Bug 943274]. This is the same problem
	* generic/tclIO.h: as [SF Tcl Bug 462317], see ChangeLog entry
		   2001-09-26. The fix done at that time is incomplete. It
		   is possible to get around it if the actual read
		   operation is defered and not executed in the event
		   handler itself. Instead of tracking if we are in an
		   read caused by a synthesized fileevent we now track if
		   the OS has delivered a true event = actual data and
		   bypass the driver if a read finds that there is no
		   actual data waiting. The flag is cleared by a short or
		   full read.

	  ***POTENTIAL INCOMPATIBILITY*** for channel drivers.

2004-05-17  Vince Darley  <[email protected]>

	* generic/tclPathObj.c: fix to (Bug 956063) in 'file dirname'.
	* tests/cmdAH.test: added test for this bug.

	* doc/FileSystem.3: better documentation of refCount requirements
	of some FS functions (Bug 956126)

2004-05-19  Donal K. Fellows  <[email protected]>

	* generic/tclTest.c (TestgetintCmd): Made the tests in get.test check
	* tests/get.test:		     Tcl_GetInt() since the core now
					     avoids that function.

	* generic/tclCompile.c:
	* generic/tclExecute.c: changed implementation of {expand}, last
	chance while in alpha as ...

	***POTENTIAL INCOMPATIBILITY***
	Scripts precompiled with ProComp under previous tcl8.5a versions
	may malfunction due to changed instruction numbers for
	INST_LIST_INDEX_IMM, INST_LIST_RANGE_IMM and INST_START_CMD.

2004-05-14  Kevin B. Kenny  <[email protected]>

	* generic/tclInt.decls:	     Promoted TclpLocaltime and TclpGmtime
	* generic/tclIntDecls.h:     from Unix-specific stubs to the generic
	* generic/tclIntPlatDecls.h: internal Stubs table.  Reran 'genstubs'
	* generic/tclStubInit.c:
	* unix/tclUnixPort.h:

	* generic/tclClock.c: Changed a buggy 'GMT' timezone specification
			      to the correct 'GMT0'. [Bug #922848]

	* unix/tclUnixThrd.c: Moved TclpGmtime and TclpLocaltime to
			      unix/tclUnixTime.c where they belong.

	* unix/tclUnixTime.c (TclpGmtime, TclpLocaltime, TclpGetTimeZone,
			      ThreadSafeGMTime [removed],
			      ThreadSafeLocalTime [removed],
			      SetTZIfNecessary, CleanupMemory):
	    Restructured to make sure that the same mutex protects
	    all calls to localtime, gmtime, and tzset.	Added a check
	    in front of those calls to make sure that the TZ env var
	    hasn't changed since the last call to tzset, and repeat
	    tzset if necessary. [Bug #942078]  Removed a buggy test
	    of the Daylight Saving Time information in 'gettimeofday'
	    in favor of applying 'localtime' to a known value.
	    [Bug #922848]

	(eePtr). First step towards a change in the execution stack
	management - it is now only used within TEBC.

2004-05-13  Donal K. Fellows  <[email protected]>

	TIP#143 IMPLEMENTATION

	* generic/tclExecute.c (TclCompEvalObj, TclExecuteByteCode):

	* generic/tclInterp.c (Tcl_Limit*): Public limit API.
	* generic/tcl.decls:
	* tests/interp.test: Basic tests of command limits.

	* doc/binary.n:		TIP#129 IMPLEMENTATION [Patch 858211]

	'glob -types d' (Bug 951489)

2004-05-11  Donal K. Fellows  <[email protected]>

	* doc/scan.n: Updated the examples to be clearer about their
	relevance to the scan command.

	(TclpCreateProcess): When under NT, with no console, and executing a
	DOS application, the path priming does not need an ending space as
	BuildCommandLine() will do this for us.

2004-05-08  Vince Darley  <[email protected]>

	* generic/tclFileName.c:
	* generic/tclIOUtil.c: remove some compiler warnings on MacOS X.

2004-05-07  Chengye Mao <[email protected]>

	* win/tclWinPipe.c: refixed bug 789040 re-entered in rev 1.41.
	Let's be careful and don't re-enter previously fixed bugs.

	embedded null characters between real nullbytes and the internal
	representation on input/output (Bug #949905).

2004-05-07  Vince Darley  <[email protected]>

	* generic/tclFileName.c:
	* generic/tclIOUtil.c:
	* generic/tclFileSystem.h:
	* tests/fileSystem.test: fix for [Bug 943995], in which vfs-
	registered root volumes were not handled correctly as glob
	patterns in all circumstances.

2004-05-06  Miguel Sofer <[email protected]>

	* generic/tclInt.h:
	* generic/tclObj.c (TclFreeObj): made TclFreeObj use the new macro
	TclFreeObjMacro(), so that the allocation and freeing of Tcl_Obj
	is defined in a single spot (the macros in tclInt.h), with the
	exception of the TCL_MEM_DEBUG case.
	The #ifdef logic for the corresponding macros has been reformulated
	to make it clearer.

2004-05-05  Donal K. Fellows  <[email protected]>

	* doc/break.n, doc/continue.n, doc/for.n, doc/while.n: More examples.

2004-05-05  Don Porter	<[email protected]>

	* tests/unixInit.test (unixInit-2.10):	Test correction for Mac OSX.
	Be sure to consistently compare normalized path names.	Thanks to
	Steven Abner (tauvan).	[Bug 948177]

2004-05-05  Donal K. Fellows  <[email protected]>

	* doc/CrtObjCmd.3: Remove reference to Tcl_RenameCommand; there is
	no such API. [Bug 848440]

2004-05-05  David Gravereaux <[email protected]>

	* win/tclWinSock.c (SocketEventProc) : connect errors should
	fire both the readable and writable handlers because this is
	how it works on UNIX [Bug 794839]

	* generic/tclEncoding.c (TclFinalizeEncodingSubsystem):
	FreeEncoding(systemEncoding); moved to before the hash table
	itereation as it was causing a double free attempt under some
	conditions.

	* win/coffbase.txt: Added the tls extension to the list of
	preferred load addresses.

2004-05-04  Jeff Hobbs	<[email protected]>

	* tests/fileSystem.test (filesystem-1.39): replace 'file volumes'
	* tests/fileName.test (filename-12.9,10):  lindex with direct C:/
	hard-coded because A:/ was being used and that is empty for most.

	* tests/winFCmd.test (winFCmd-16.12): test volumerelative $HOME

2004-05-04  Don Porter	<[email protected]>

	* generic/tclAlloc.c:		Make sure Tclp*Alloc* routines get

	more permanent replacement.

2004-04-30  Kevin B. Kenny   <[email protected]>

	* generic/tclThreadAlloc.c: Added a temporary (or so I hope!)
	inclusion of "tclWinInt.h" to avoid problems when compiling
	on Win32-VC++ with --enable-threads.  [Bug 945447]

2004-04-30  Donal K. Fellows  <[email protected]>

2004-04-26  Donal K. Fellows  <[email protected]>

	* doc/open.n, doc/close.n: Updated (thanks to David Welton) to be
	clearer about pipeline errors and added example to open(n) that shows
	simple pipeline use.  [Patches 941377,941380]

	* doc/DictObj.3: Added warning about the use of Tcl_DictObjDone and an
	example of use of iteration. [Bug 940843]

	* doc/Thread.3: Reworked to remove references to testing interfaces
	and instead promote the use of the Thread package. [Patch 932527]
	Also reworked and reordered the page for better readability.

2004-04-25  Don Porter	<[email protected]>

2004-04-15  Donal K. Fellows  <[email protected]>

	* generic/tclClock.c (Tcl_ClockObjCmd): Minor fault in a [clock
	clicks] error message.

2004-04-06  Don Porter	<[email protected]>

	Patch 922727 committed.	 Implements three changes:

	* generic/tclInt.h:	Reworked the Tcl header files into a clean
	* unix/tclUnixPort.h:	hierarchy where tcl.h < tclPort.h < tclInt.h
	* win/tclWinInt.h:	and every C source file should #include
	* win/tclWinPort.h:	at most one of those files to satisfy its
	declaration needs.  tclWinInt.h and tclWinPort.h also better organized
	so that tclWinPort.h includes the Windows implementation of
	cross-platform declarations, while tclWinInt.h makes declarations that
	are available on Windows only.

	* tests/unixInit.test (unixInit-3.1):	Default encoding on Darwin
	systems is utf-8.  Thanks to Steven Abner (tauvan).  [Bug 928808]

2004-04-06  Donal K. Fellows  <[email protected]>

	* tests/cmdAH.test (cmdAH-18.2): Added constraint because
	access(...,X_OK) is defined to be permitted to be meaningless when
	running as root, and OSX exhibits this.	 [Bug 929892]

2004-04-02  Miguel Sofer <[email protected]>

	* generic/tclCompile.c:
	* generic/tclInt.h: removed the macro TCL_ALIGN() from tclInt.h,
	replaced by the static macro ALIGN() in tclCompile.c [Bug 926445]

2004-04-02  Miguel Sofer <[email protected]>

	* generic/tclCompile.h: removed redundant #ifdef _TCLINT

2004-04-01  Vince Darley  <[email protected]>

	* generic/tclIOUtil.c:	 Fix to privately reported vfs bug with
	'glob -type d -dir . *' across a vfs boundary.	No tests for
	this are currently possible without effectively moving tclvfs
	into Tcl's test suite.

2004-03-31  Don Porter	<[email protected]>

	* doc/msgcat.n:	Clarified message catalog file encodings. [Bug 811457]
	* library/msgcat/msgcat.tcl:
	Updated internals to make use of [dict]s to store message catalog
	data and to use [source -encoding utf-8] to access catalog files.
	Thanks to Michael Sclenker.  [Patch 875055, RFE 811459]
	Corrected [mcset] to be able to successfully set a translation to
	the empty string.  [mcset $loc $src {}] was incorrectly set the
	$loc translation of $src back to $src.	Also changed [ConvertLocale]
	to minimally require a non-empty "language" part in the locale value.
	If not, an error raised prompts [Init] to keep looking for a valid
	locale value, or ultimately fall back on the "C" locale. [Bug 811461].
	* library/msgcat/pkgIndex.tcl:	Bump to msgcat 1.4.1.

2004-03-30  Donal K. Fellows  <[email protected]>

	* generic/tclHash.c (HashStringKey): Cleaned up. This function is
	not faster, but it is a little bit clearer.
	* generic/tclLiteral.c (HashString): Applied logic from HashObjKey.
	* generic/tclObj.c (HashObjKey): Rewrote to fix fault which hashed
	every single-character object to the same hash bucket.	The new
	code is shorter, simpler, clearer, and (happily) faster.

2004-03-30  Miguel Sofer <[email protected]>

	* generic/tclExecute.c (TEBC): reverting to the previous method
	for async tests in TEBC, as the new method turned out to be too
	costly. Async tests now run every 64 instructions.

2004-03-30  Miguel Sofer <[email protected]>

	* generic/tclCompile.c:	    New instruction code INST_START_CMD
	* generic/tclCompile.h:	    that allows checking the bytecode's
	* generic/tclExecute.c:	    validity [Bug 729692] and the interp's
	* tests/interp.test (18.9): readyness [Bug 495830] before running
	* tests/proc.test (7.1):    the command. It also changes the
	* tests/rename.test (6.1):  mechanics of the async tests in TEBC,
	doing it now at command start instead of every 16 instructions.

2004-03-30  Vince Darley  <[email protected]>

	* generic/tclFileName.c:  Fix to Windows glob where the pattern is
	* generic/tclIOUtil.c:	  a volume relative path or a network
	* tests/fileName.test:	  share [Bug 898238]. On windows 'glob'
	* tests/fileSystem.test:  will now return the results of
	'glob /foo/bar' and 'glob \\foo\\bar' as 'C:/foo/bar', i.e. a
	correct absolute path (rather than a volume relative path).

	Note that the test suite does not test commands like
	'glob //Machine/Shared/*' (on a network share).

2004-03-30  Vince Darley  <[email protected]>

	* generic/tclPathObj.c:	  Fix to filename bugs recently
	* tests/fileName.test:	  introduced [Bug 918320].

2004-03-29  Don Porter	<[email protected]>

	* generic/tclMain.c (Tcl_Main, StdinProc):	Append newline only
	* tests/basic.test (basic-46.1):		to incomplete scripts
	as part of multi-line script construction.  Do not add an extra
	trailing newline to the complete script.  [Bug 833150]

2004-03-28  Miguel Sofer <[email protected]>

	* generic/tclCompile.c (TclCompileScript): corrected possible
	segfault when a compilation returns TCL_OUTLINE_COMPILE after
	having grown the compile environment [Bug 925121].

2004-03-27  Miguel Sofer <[email protected]>

	* doc/array.n: added documentation for trace-realted behaviour of
	'array get' [Bug 449893]

	* generic/tclIntDecls.h: Made HEAD build on Solaris again by
	applying fix recommended by Don Porter.

2004-03-18  Reinhard Max  <[email protected]>

	* generic/tclIntDecls.h: Removed TclpTime_t. It wasn't really needed,
	* generic/tclInt.h:	 but caused warnings related to
	* generic/tclInt.decls:	 strict aliasing with GCC 3.3.
	* generic/tclClock.c:
	* generic/tclDate.c:
	* generic/tclGetDate.y:

	* unix/tcl.m4:		 Removed -Wno-strict-aliasing.

2004-03-18  Daniel Steffen  <[email protected]>

	Removed support for Mac OS Classic platform [Patch 918142]

	* README:
	* compat/string.h:

2004-03-17  Donal K. Fellows  <[email protected]>

	* doc/lsearch.n: Improved examples on the advanced capabilities of
	lsearch (with the right options, set element removal can be done)
	following discussion on tkchat.

2004-03-16  Don Porter	<[email protected]>

	* doc/catch.n:	Compiled [catch] no longer fails to catch syntax
	errors.	 Removed the claims in the documentation that it does.
	* doc/return.n:	Updated example to use [dict merge].

2004-03-16  Jeff Hobbs	<[email protected]>

	* unix/configure, unix/tcl.m4: add -Wno-strict-aliasing for GCC to
	suppress useless type puning warnings.

2004-03-16  Donal K. Fellows  <[email protected]>

	* doc/file.n: *roff formatting fix. [Bug 917171]

	IMPLEMENTATION OF TIP#163
	* generic/tclDictObj.c (DictMergeCmd):	This is based on work by Joe
	* tests/dict.test (dict-20.*):		English in Tcl [FRQ 745851]
	* doc/dict.n:				but not exactly.

2004-03-10  Kevin B. Kenny <[email protected]>

	* generic/tclGetDate.y (TclGetDate): Fix so that
	[clock scan <timeOfDay> -gmt true] uses the GMT base date
	instead of the local one. [Bug 913513]
	* tests/clock.test: Added test cases for wrong ISO8601 week number
	[Bug 500285] and wrong GMT base date [Bug 913513].  Several tests
	still fail on Windows, and these are actual faults in [clock scan].
	Fix is still pending.
	* generic/tclDate.c: Regenerated.

2004-03-08  Vince Darley  <[email protected]>

	* generic/tclFileName.c:  Fix to 'glob -path' near the root
	* tests/fileName.test:	  of the filesystem. [Bug 910525]

2004-03-08  Don Porter	<[email protected]>

	* generic/tclParse.c (TclParseInit):	Modified TclParseInit so
	* generic/tclTest.c ([testexprparser]): that Tcl_Parse initialization
	conforms to documented promised about what fields will not be
	modified by what Tcl_Parse* routines. [Bug 910595]

2004-03-05  Mo DeJong  <[email protected]>

2004-03-05  Kevin B. Kenny <[email protected]>

	* tests/registry.test: Applied fix from Patch #910174 to
	make the test for an English-language system include any
	country code, rather than just English-United States.1252.
	Thanks to Pat Thoyts for the changes.

2004-03-04  Pat Thoyts	<[email protected]>

	* tests/registry.test: Applied fixed from #766159 to skip two
	tests on Win98 that depend on a Unicode registry (NT specific).

2004-03-04  Don Porter	<[email protected]>

	* generic/tclInt.h (TclParseInit):	Factored the common code
	* generic/tclParse.c (TclParseInit):	for initializing a Tcl_Parse
	* generic/tclParseExpr.c:		struct into one routine.

2004-03-04  Pat Thoyts	<[email protected]>

	* library/reg/pkgIndex.tcl:  Added TIP #100 support to the
	* win/tclWinReg.c:	     registry package (patch #903831)
	This provides a Windows test of the TIP #100 mechanism and
	a sample to show how unloading an extension can be done.

2004-03-04  Donal K. Fellows  <[email protected]>

	* unix/dltest/pkgua.c: Fix minor syntax problems. [Bug 909288]

2004-03-03  Jeff Hobbs	<[email protected]>

	*** 8.5a1 TAGGED FOR RELEASE ***

	* changes: updated for 8.5a1

2004-03-03  David Gravereaux <[email protected]>

	* win/makefile.vc: default environment variable for VC++ is
	%MSDevDir% not %MSVCDir%, although vcvars32.bat sets both.

	* win/tclWinNotify.c (Tcl_WaitForEvent) : Allows an idling
	notifier to service "Asynchronous Procedure Calls" from its wait
	state.	Only useful for extension authors who decide they might
	want to try "completion routines" with WriteFileEx(), as an
	example.  From experience, I recommend that "completion	ports"
	should be used instead as the execution of the callbacks are more
	managable.

2004-03-01  Jeff Hobbs	<[email protected]>

	* README:	    update patchlevel to 8.5a1
	* generic/tcl.h:
	* tools/tcl.wse.in, tools/tclSplash.bmp:
	* unix/configure, unix/configure.in, unix/tcl.spec:
	* win/README.binary, win/configure, win/configure.in:

	* unix/tcl.m4: update HP-11 build libs setup

2004-03-01  Don Porter	<[email protected]>

	* unix/tcl.m4 (SC_CONFIG_CFLAGS):	Allow 64-bit enabling on
	IRIX64-6.5* systems.  [Bug 218561]
	* unix/configure:	autoconf-2.57

	* generic/tclTrace.c (TclCheckInterpTraces):	The TIP 62
	* generic/tclTest.c (TestcmdtraceCmd):	implementation introduced a

	* generic/tclLoad.c (Tcl_LoadObjCmd): Missing dereference caused
	segfault with non-loadable extension. [Bug 904307]

	* unix/tclUnixChan.c (TcpGetOptionProc): Stop memory leak with
	very long hostnames.  [Bug 888777]

2004-02-25  Pat Thoyts	<[email protected]>

	* win/tclWinDde.c: Removed some gcc warnings - except for the
	-Wconversion warning for GetGlobalAtomName. gcc is just wrong
	about this.

2004-02-24  Donal K. Fellows  <[email protected]>

	IMPLEMENTATION OF TIP#100 FROM GEORGIOS PETASIS
	* generic/tclLoad.c (Tcl_UnloadObjCmd): Implementation.

2004-02-17  Don Porter	<[email protected]>

	* doc/tcltest.n:
	* library/tcltest/tcltest.tcl:	Changed -verbose default value to
	{body error} so that detailed information on unexpected errors in
	tests is provided by default, even after the fix for [Bug 725253]

2004-02-17  Jeff Hobbs	<[email protected]>

	* tests/unixInit.test (unixInit-7.1):
	* unix/tclUnixInit.c (TclpInitPlatform): ensure the std fds exist
	to prevent crash condition [Bug #772288]

2004-02-17  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c (TclCompileSwitchCmd): Bozo mistake in
	memory releasing order when in an error case.  [Bug 898910]

2004-02-16  Jeff Hobbs	<[email protected]>

	* generic/tclTrace.c (TclTraceExecutionObjCmd)
	(TclTraceCommandObjCmd): fix possible mem leak in trace info.

2004-02-12  Mo DeJong  <[email protected]>

	* win/tclWinInit.c (AppendEnvironment):
	Use the tail component of the passed in
	lib path instead of just blindly using
	lib+4. That worked when lib was "lib/..."
	but fails for other values. Thanks go to
	Patrick Samson for pointing this out.

2004-02-10  David Gravereaux  <[email protected]>

	* win/nmakehlp.c: better macro grepping logic.

2004-02-07  David Gravereaux  <[email protected]>

	* win/makefile.vc:
	* win/rules.vc:
	* win/tcl.rc:
	* win/tclsh.rc:	 Added an 'unchecked' option to the OPTS macro so a
	core built with symbols can be linked to the non-debug enabled C
	run-time.  As per discussion with Kevin Kenny.	Called like this:

		nmake -af makefile.vc OPTS=unchecked,symbols

	This clarifies the meaning of the 'g' naming suffix to mean only that
	the binary requires the debug enabled C run-time.  Whether the binary
	contains symbols or not is a different condition.

2004-01-29  Vince Darley  <[email protected]>

	* generic/tclPathObj.c: fix to [Bug 883143] in file normalization

2004-01-29  Vince Darley  <[email protected]>

	* doc/file.n:
	* generic/tclFCmd.c
	* generic/tclTest.c
	* library/init.tcl
	* mac/tclMacFile.c
	* tests/fileSystem.test: fix to [Bug 886352] where 'file copy
	-force' had inconsistent behaviour wrt target files with
	insufficient permissions, particular from vfs->native fs.

	Many other minor whitespace/style fixes to this file too.

2004-01-27  David Gravereaux <[email protected]>

	* win/nmakehlp.c: Use '.\nul' as the sourcefile name instead of
	'nul' so VC 5.2 doesn't try searching the path for it and failing
	with a possible dialogbox popping up about having to add a CD to
	an empty drive.	 Also added a SetErrorMode() call to disable any
	dialogs that cl.exe or link.exe might create.  [Bug 885537]

2004-01-22  Vince Darley  <[email protected]>

	* doc/file.n: clarified documentation of 'file system' [Bug 883825]
	* tests/fCmd.test: improved test result in failure case.

2004-01-22  Vince Darley  <[email protected]>

	* tests/fileSystem.test: 3 new tests
	* generic/tclPathObj.c: fix to [Bug 879555] in file normalization.
	* doc/filename.n: small clarification to Windows behaviour with
	filenames like '.....', 'a.....', '.....a'.

	* generic/tclIOUtil.c: slight improvement to native cwd caching
	on Windows.

2004-01-21  David Gravereaux <[email protected]>

	* doc/Panic.3:	Mentions of 'panic' and 'panicVA' removed from
	the documentation.

2004-01-21  Vince Darley  <[email protected]>

	* doc/FileSystem.3:
	* generic/tcl.decls:
	* generic/tclCmdAH.c
	* generic/tclDecls.h
	* generic/tclFCmd.c
	* generic/tclFileName.c
	* generic/tclFileSystem.h
	* generic/tclIOUtil.c
	* generic/tclInt.decls

	applied a round of filesystem optimisation with better handling
	and caching of relative and absolute paths, requiring fewer
	conversions.  (3) clarifications to the documentation,
	particularly regarding the acceptable refCounts of objects.
	Some new tests added.  Tcl benchmarks show a significant
	improvement over 8.4.5, and on Windows typically a small
	improvement over 8.3.5 (Unix still appears to require
	optimisation).	TCL_FILESYSTEM_VERSION_2 introduced, but for
	internal use only.  There should be no public incompatibilities
	from these changes.  Thanks to dgp for extensive testing.

2004-01-19  David Gravereaux <[email protected]>

	* win/tclWinPipe.c (Tcl_WaitPid): Fixed a thread-safety problem
	with the process list.	The delayed cut operation after the wait
	was going stale by being outside the list lock.	 It now cuts
	within the lock and does a locked splice for when it needs to
	instead.  [Bug 859820]

2004-01-18  Donal K. Fellows  <[email protected]>

	* generic/tclCompile.c, generic/tclCompile.h: Two new opcodes,
	INST_LIST_INDEX_IMM and INST_LIST_RANGE_IMM, that have operand(s)

2004-01-15  David Gravereaux <[email protected]>

	* win/tclWinReg.c:  Placed the requirement for advapi.lib into
	the object file itself with #paragma comment (lib, ...) when
	built with VC++.  This will simplify linking for users of the
	static library.

	* win/rules.vc:	 Added new 'fullwarn' to the CHECKS commandline
	macro; sets $(FULLWARNINGS).

	* win/makefile.vc:  Removed 'advapi.lib' from $(baselibs).
	Added new logic to crank-up the warning levels for both compile
	and link when $(FULLWARNINGS) is set.  Some clean-up with how
	the resource files are built and how -DTCL_USE_STATIC_PACKAGES
	is sent when compiling the shells.

	* win/tclAppInit.c: Small change in how TCL_USE_STATIC_PACKAGES
	is used.

	* win/tcl.rc:
	* win/tclsh.rc: Some clean-up with how the resource files are
	built.	Fixed 'OriginalFilename' problem that still thought
	a debug suffix was still 'd', now is 'g'.

2004-01-14  Donal K. Fellows  <[email protected]>

	* generic/tclDictObj.c (TraceDictPath, DictExistsCmd): Adjusted
	behaviour of [dict exists] so a failure to look up a dictionary
	along the path of dicts doesn't trigger an error.  This is how it
	was documented to behave previously...	[Bug 871387]

	* generic/tclDictObj.c: Assorted dict fixes from Peter Spjuth
	relating to [Bug 876170].
	(SetDictFromAny): Make sure that lists retain their ordering even
	when converted to dictionaries and back.
	(TraceDictPath): Correct object reference count handling!
	(DictReplaceCmd, DictRemoveCmd): Stop object leak.
	(DictIncrCmd,DictLappendCmd,DictAppendCmd,DictSetCmd,DictUnsetCmd):
	Simpler handling of reference counts when assigning to variables.
	* tests/dict.test (dict-19.2): Memory leak stress test

2004-01-13  Don Porter	<[email protected]>

	* generic/tclCmdMZ.c (Tcl_SwitchObjCmd):  Silence compiler warnings.

	Patch 876451: restores performance of [return].	 Also allows forms
	such as [return -code error $msg] to be bytecompiled.

	* generic/tclInt.h:	Factored Tcl_ReturnObjCmd() into two pieces:
	* generic/tclCmdMZ.c:	TclMergeReturnOptions(), which can parse the
	options to [return], check their validity, and create the
	corresponding return options dictionary, and TclProcessReturn(),
	which takes that return options dictionary and performs the

	Create fresh objects instead of using the one currently in the
	interpreter, which isn't guaranteed to be fresh and unshared. The
	cost for the core will be minimal because of the object cache, and
	this fixes [Bug 875395].

2004-01-12  Miguel Sofer <[email protected]>

	* generic/tclCompExpr.c (CompileLandOrLorExpr): cosmetic changes.

2004-01-12  Miguel Sofer <[email protected]>

	* generic/tclCompExpr.c (CompileLandOrLorExpr): new logic, fewer
	instructions. As a side effect, the instructions INST_LOR and
	INST_LAND are now never used.
	* generic/tclExecute.c (INST_JUMP*): small optimisation; fix a
	bug in debug code.

2004-01-11  David Gravereaux <[email protected]>

	* win/tclWinThrd.c (Tcl_ConditionNotify): condPtr must be
	dereferenced to see if there are waiters else uninitialized
	datum is manipulated.  [Bug 849007 789338 745068]

2004-01-09  David Gravereaux <[email protected]>

	* generic/tcl.h: Renamed and deprecated #defines moved to within
	the #ifndef TCL_NO_DEPRECATED block.  This allows us to build Tcl
	to check for deprecated functions in use, such as panic() and
	Tcl_Ckalloc().	By request from DKF.  Extensions that build
	with -DTCL_NO_DEPRECATED now have these macros as restricted.
	***POTENTIAL INCOMPATIBILITY***

	* win/makefile.vc:
	* win/rules.vc:	 Added -DTCL_NO_DEPRECATED usage to makefile.vc.
	Called like this:   nmake -af makefile.vc CHECKS=nodep

2004-01-09  Vince Darley  <[email protected]>

	* generic/tclIOUtil.c: fix to infinite loop in
	TclFinalizeFilesystem [Bug 873311]

.SH DESCRIPTION
.PP
.VS 8.5
The \fBTcl_SetReturnOptions\fR and \fBTcl_GetReturnOptions\fR
routines expose the same capabilities as the \fBreturn\fR and
\fBcatch\fR commands, respectively, in the form of a C interface.
.PP
\fBTcl_GetReturnOptions\fR retrieves the dictionary of return options
from an interpreter following a script evaluation.
Routines such as \fBTcl_Eval\fR are called to evaluate a
script in an interpreter.  These routines return an integer
completion code.  These routines also leave in the interpreter
both a result and a dictionary of return options generated
by script evaluation.  Just as \fBTcl_GetObjResult\fR retrieves
the result, \fBTcl_GetReturnOptions\fR retrieves the dictionary
of return options.  The integer completion code should be
passed as the \fIcode\fR argument to \fBTcl_GetReturnOptions\fR
so that all required options will be present in the dictionary.
Specifically, a \fIcode\fR value of \fBTCL_ERROR\fR will
ensure that entries for the keys \fB-errorinfo\fR,
\fB-errorcode\fR, and \fB-errorline\fR will appear in the
dictionary.  Also, the entries for the keys \fB-code\fR
and \fB-level\fR will be adjusted if necessary to agree
with the value of \fIcode\fR.  The \fB(Tcl_Obj *)\fR returned

The best time to call \fBTcl_AddErrorInfo\fR is just after
a script evaluation routine has returned \fBTCL_ERROR\fR.
The value of the \fB-errorline\fR return option (retrieved
via a call to \fBTcl_GetReturnOptions\fR) often makes up
a useful part of the \fImessage\fR passed to \fBTcl_AddErrorInfo\fR.
.PP
\fBTcl_AddObjErrorInfo\fR is nearly identical
to \fBTcl_AddErrorInfo\fR, except that it has an additional \fIlength\fR
argument.  This allows the \fImessage\fR string to contain 
embedded null bytes.  This is essentially never a good idea.
If the \fImessage\fR needs to contain the null character \fBU+0000\fR,
Tcl's usual internal encoding rules should be used to avoid
the need for a null byte.  If the \fBTcl_AddObjErrorInfo\fR
interface is used at all, it should be with a negative \fIlength\fR value.
.PP

corresponding return options.  It has long been emphasized
in this manual page that it is important to 
call the procedures described here rather than
setting \fBerrorInfo\fR or \fBerrorCode\fR directly with
\fBTcl_ObjSetVar2\fR.
.PP
If the procedure \fBTcl_ResetResult\fR is called,
it clears all of the state of the interpreter associated with
script evaluation, including the entire return options dictionary.
In particular, the \fB-errorinfo\fR and \fB-errorcode\fR options
are reset.  
If an error had occurred, the \fBTcl_ResetResult\fR call will
clear the error state to make it appear as if no error had
occurred after all.
The global variables \fBerrorInfo\fR and
\fBerrorCode\fR are not modified by \fBTcl_ResetResult\fR
so they continue to hold a record of information about the
most recent error seen in an interpreter.

allocation could have been in progress when the event occurred.
The only safe approach is to set a flag indicating that the event
occurred, then handle the event later when the world has returned
to a clean state, such as after the current Tcl command completes.
.PP
\fBTcl_AsyncCreate\fR, \fBTcl_AsyncDelete\fR, and \fBTcl_AsyncReady\fR
are thread sensitive.  They access and/or set a thread-specific data
structure in the event of a core built with \fI\-\-enable\-threads\fR.  The token
created by \fBTcl_AsyncCreate\fR contains the needed thread information it
was called from so that calling \fBTcl_AsyncMark\fR(\fItoken\fR) will only yield
the origin thread into the asynchronous handler.
.PP
\fBTcl_AsyncCreate\fR creates an asynchronous handler and returns
a token for it.
The asynchronous handler must be created before
any occurrences of the asynchronous event that it is intended
to handle (it is not safe to create a handler at the time of
an event).
When an asynchronous event occurs the code that detects the event

.SH SYNOPSIS

If \fIcountPtr\fR isn't NULL, \fI*countPtr\fR gets filled

the backslash character.
.BE

.SH DESCRIPTION
.PP

The use of \fBTcl_Backslash\fR is deprecated in favor of
\fBTcl_UtfBackslash\fR.
.PP
This is a utility procedure provided for backwards compatibility with
non-internationalized Tcl extensions.  It parses a backslash sequence and
returns the low byte of the Unicode character corresponding to the sequence. 

\fBTcl_Backslash\fR modifies \fI*countPtr\fR to contain the number of
characters in the backslash sequence.
.PP
See the Tcl manual entry for information on the valid backslash sequences.
All of the sequences described in the Tcl manual entry are supported by
\fBTcl_Backslash\fR.
