2005-11-11  Miguel Sofer <msofer@users.sf.net>

	* generic/tclBasic.c (Tcl_DeleteCommandFromToken):
	* generic/tclObj.c (Tcl_GetCommandFromObj): bump the cmd epoch
	early to insure that cached references to this command are
	invalidated. Partial fix for [Bug 1352734] - at least insures that
	namespace-51.13 does not cause a panic. The test is still marked
	as knownbug, pending resolution of what is actually the correct
	return value ([Bug 1354540])
	
	
2005-11-09  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclTimer.c: Changed [after] so that it behaves correctly
	* tests/timer.test:   with negative arguments [Bug 1350293] and
	                      arguments that overflow a 32-bit word
	                      [Bug 1350291].
	
2005-11-08  Don Porter  <dgp@users.sourceforge.net>

	* tests/compile.test:	Updated tests with changed behavior
	* tests/execute.test:	due to addition of bignums.
	* tests/expr-old.test:
	* tests/expr.test:
	* tests/parseExpr.test:
	* tests/platform.test:
	* tests/string.test:

2005-11-08  Jeff Hobbs  <jeffh@ActiveState.com>

	* unix/tclUnixFCmd.c (MAX_READDIR_UNLINK_THRESHOLD): reduce to 130
	based on errors seen on OS X 10.3 with lots of links in a dir.
	[Bug 1034337 followup]

2005-11-09  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* unix/Makefile.in (gdb-test): Added a new target to make it easier to
	run the test suite inside a debugger.

2005-11-08  Don Porter  <dgp@users.sourceforge.net>

	* tests/compExpr-old.test:	Updated tests with changed behavior
	due to addition of bignums.

        * tests/expr.test:      Portable tests expr-46.13-18 [Bug 1341368]

	* generic/tclPkg.c:	Corrected inconsistencies in the value returned
	* tests/pkg.test:	by Tcl_PkgRequire(Ex) so that the returned
	values will always agree with what is stored in the package database.
	This way repeated calls to Tcl_PkgRequire(Ex) have the same results.
	Thanks to Hemang Lavana.  [Bug 1162286].

2005-11-08  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclTrace.c (TraceVarEx): Factor out the core of Tcl_TraceVar2
	(TclTraceVariableObjCmd,TraceVarProc): Use the new internal API to
	arrange for the clientData to be cleaned up at the same time as the
	rest of the main trace record. This simplifies the code a bit at the
	same time.

2005-11-07  Miguel Sofer <msofer@users.sf.net>

	* tests/trace.test (trace-13.2-4): added tests to detect leak, see [Bug
	1348775]. The recently added trace-8.9 test is now 13.4.

2005-11-07  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* tests/dict.test (dict-19.2): arrange for the stress testing code to
	only stress test the dict code and not the trace code as well. [Bug
	1342858]

2005-11-05  Miguel Sofer <msofer@users.sf.net>

	* tests/trace.test (trace-8.9): added test to detect leak, see [Bug
	1348775].

2005-11-04  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/tclWinPort.h:  Applied [Patch 1267871] by Matt Newman for
	* win/tclWinPipe.c:  extended error code support on Windows.
	* tests/exec.test:   Tests for extended error codes.
	* generic/tclPipe.c: Permit long codes (platform macros permitting).

2005-11-04  Miguel Sofer <msofer@users.sf.net>

	* generic/tclBinary.c:
	* generic/tclCmdAH.c:
	* generic/tclCmdIL.c:
	* generic/tclCmdMZ.c:
	* generic/tclDictObj.c:
	* generic/tclExecute.c:
	* generic/tclIOCmd.c:
	* generic/tclLink.c:
	* generic/tclTest.c:
	* generic/tclVar.c: fix for [Bug 1334947]. The functions TclPtrSetVar,
	Tcl_ObjSetVar2 and Tcl_SetVar2Ex now always consume the newValuePtr
	argument - i.e., they will free a 0-refCount object if they failed to
	set the variable. Fixed all callers in the core.

2005-11-04  Kevin Kenny  <kennykb@acm.org>

	* generic/tclGetDate.y: Added abbreviations for the Korean
	* library/clock.tcl:    timezone. [Patch 1298737]
	* generic/tclDate.c:    Regenerated.

	* tools/findBadExternals.tcl: Added this script, which locates
	external symbols that do not begin with 'Tcl' or 'tcl' and hence might
	be in conflict with other link libraries. Thanks to George Peter
	Staplin for the idea and the initial version of the script. [Bug
	1263012]

	* unix/Makefile.in: Trimmed a bunch of fat out of the tommath/
	directory in 'make dist'. [RFE 1333318]

	* unix/tcl.m4: Added code to enable [load] on LynxOS. Thanks to
	heidibr@users.sf.net for the patch. [Bug 1163896]. Removed the last
	vestiges of GNU dld from the Unix build [RFE 1071992].

	* unix/tclLoadDld.c: Removed.
	* unix/configure: Regenerated.

2005-11-04  Miguel Sofer <msofer@users.sf.net>

	* generic/tclInt.h:
	* generic/tclNamesp.c:
	* generic/tclVar.c:
	* tests/trace.test: fix for [Bugs 1338280/1337229]; changed to use the
	same approach as the 8.4 patch in the ticket (i.e., removed the patch
	committed on 2005-31-10).

2005-11-03  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* win/tclWin32Dll.c:   Applied [Patch 1256872] to provide unicode
	* win/tclWinConsole.c: support in the console on suitable systems.
	* win/tclWinInt.h:     Patch by Anton Kovalenko

2005-11-02  Pat Thoyts  <patthoyts@users.sourceforge.net>

	Applied [Patch 1096916] to support building with MSVC 8.
	* generic/regerror.c: Avoid use of reserved word.
	* generic/tcl.h:      Select the right Tcl_Stat structure
	* generic/tclDate.c:  Casts to handle 64 bit time_t case.
	* tests/env.test:     Include essential envvar on Win32
	* win/nmakehlp.c:     Handle new return codes.
	* win/makefile.vc:    Use the selected options.
	* win/rules.vc:       Check options are applicable
	* win/tclWinPort.h:   Disable deprecated function warnings
	* win/tclWinSock.c:   Provide default value to avoid warning.
	* win/tclWinTime.c:   Add casts to handle 64bit time_t type.

2005-11-01  Don Porter  <dgp@users.sourceforge.net>

        * generic/tclTrace.c (TclCheckExecutionTraces): Corrected mistaken
        assumption that all command traces are set at the script level.
        Report/fix from Jacques H. de Villiers. [Bug 1337941]

	* tests/unixNotfy.test (1.1,2):	Update error message whitespace to
	match changes in code.

	* tests/expr-old.test (expr-32.52):     Use int(.) to restrict result
	of left shift to the C long range.

	* expr.test (expr-46.13):	Added test that illustrates
	shortcoming of Patch 1340260.

2005-10-31  Miguel Sofer <msofer@users.sf.net>

	* generic/tclNamesp.c: fix for [Bugs 1338280/1337229]. Thanks Don.
	* tests/trace.test: fix duplicate test numbers

2005-10-31  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* win/tclWinSerial.c (SerialSetOptionProc): Cleaned up option parsing
	to produce more informative error messages and separate error and
	non-error code paths better.
	* tests/ioCmd.test (iocmd-8-19): Updated.

2005-10-29  Miguel Sofer <msofer@users.sf.net>

	* generic/tclTrace.c (TraceVarProc): [Bug 1337229], partial fix.
	Ensure that a second call with TCL_TRACE_DESTROYED does not lead to a
	second call to Tcl_EventuallyFree(). It is still true that that second
	call should not happen, so the bug is not completely fixed.
	* tests/trace.test (test-18.3-4): added tests for [Bug 1337229] and
	[Bug 1338280].

2005-10-23  Vince Darley  <vincentdarley@sourceforge.net>

	* generic/tclFileName.c: fix to memory leak in glob [Bug 1335006] Obj
	leak detection and patch by Eric Melbardis.

	* tests/fCmd.test:
	* win/tclWinFile.c: where appropriate windows API is available, try to
	set 'nlink' and 'ino' stat fields (previously they were always 0).
	[Bug 1325803]

2005-10-22  Miguel Sofer  <msofer@users.sf.net>

	* tests/foreach.test (foreach-8.1): added test for [Bug 1189274]

2005-10-22  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (INST_INCR_*): fixed [Bug 1334570]. Obj leak
	detection and patch by Eric Melbardis.

2005-10-21  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclStrToD.c (RefineApproximation): Plugged a memory leak
	where two intermediate results were not freed on one return path. [Bug
	1334461]. Thanks to Eric Melbardis for the patch.

2005-10-21  Donal K. Fellows  <dkf@users.sf.net>

	* doc/binary.n: Clarify that virtually all code that uses the 'h'
	format in [binary scan] should be using the 'H' format instead. It is
	nearly always a bug to use the other!

2005-10-20  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclListObj.c (TclLsetFlat):
	* tests/lset.test (lset-10.3): fixed handling of unshared lists with
	shared sublists, [Bug 1333036] reported by neuronstorm.

2005-10-19  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclIORChan.c (PassReceivedError,PassReceivedErrorInterp):
	Fix crash caused by passing -1 as the length to TclNewStringObj().
	Only Tcl_NewStringObj (the function call, not the macro) handles that
	sort of thing correctly. This makes ioCmd.test pass again.

2005-10-19  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclClock.c:		Removed some dead code.
	* generic/tclCmdIL.c:
	* generic/tclCompCmds.c:
	* generic/tclDictObj.c:
	* generic/tclExecute.c:
	* generic/tclLiteral.c:
	* generic/tclParseExpr.c:
	* generic/tclScan.c:
	* generic/tclUtil.c:
	* generic/tclVar.c:

2005-10-19  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* generic/tclIORChan.c: General cleanup, removing checks that are
	unnecessary due to the general contracts of other functions in the
	core, converting to using ANSI declarations, etc. Note that nearly the
	whole file has changed, but it is often just cosmetic.

2005-10-19  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (INST_DICT_APPEND, INST_DICT_LAPPEND): fixed
	faulty peephole optimisation that can cause crashes, [Bug 1331475]
	reported by Aric Bills.

2005-10-18  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c: Added optimization for I32L64 systems to avoid
	using bignums to perform int multiplies. The improvement shows up most
	dramatically in tclbench's matrix.bench.

2005-10-15  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c:	Restored some optimizations of the
	INST_INCR_SCALAR1_IMM opcode.

2005-10-14  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>

	* generic/tclIO.c (Tcl_ClearChannelHandlers): removed change dated
	2005-10-04 (see below). Look into [Bug 1323992] for detailed
	discussion.

	* generic/tcl.h: Fixed bad definition of CRTEXPORT which should have
	been CRTIMPORT rather. This broke compilation of generic/tclMain.c and
	was probably introduced by mistage while applying the fix for [Bug
	1256937] below.

2005-10-14  Kevin Kenny  <kennykb@acm.org>

	* generic/tclExecute.c (TclIncrObj, TclExecuteByteCode): Tidied up a
	couple of infelicitous do {...} while(0) constructs.

2005-10-14  Pat Thoyts  <patthoyts@users.sourceforge.net>

	* generic/tcl.h:     Fix for [Bug 1256937] - correctly decorate
	* generic/tclMain.c: imported functions from msvcrt in static builds.

2005-10-13  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tests/format.test: "Forward"-port of test updates relating to [Bug
	1284178]. The bug itself was fixed by TIP#237.

2005-10-13  Zoran Vasiljevic  <vasiljevic@users.sourceforge.net>

	* generic/tclIO.c (Tcl_ClearChannelHandlers): temporary ifdef
	TCL_THREADS changes done to de-activate pending event processing when
	channel is being closed/cutted.

2005-10-13  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c:	Removed obsolete use of NO_ERRNO_H.
	* tools/man2tcl.c:
	* unix/tcl.m4:
	* unix/tclConfig.h.in:
	* win/configure.in:

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

	* compat/tclErrno.h:	Removed obsolete file.

	* generic/tclStrToD.c (TclParseNumber): Missing goto caused crash when
	parsing "Na". [Bug 1325833]

2005-10-12  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c (GetNumberFromObj):	Restored some lost
	optimizations for empty string values. We avoid cost of a call to
	TclParseNumber just to tell us an empty string isn't a number.

2005-10-12  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclPathObj.c (SetFsPathFromAny): TclGetString macro must not
	be combined with post-increment arguments. [Bug 1325099]

2005-10-12  Kevin Kenny  <kennykb@acm.org>

	* generic/tclExecute.c (Tcl_ExecuteByteCode, TclIncrObj): Several
	common cases inlined in hopes of gaining a little performance in
	[incr].

2005-10-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclCompCmds.c: New convenience macro CompileTokens().

2005-10-10  Don Porter  <dgp@users.sourceforge.net>

	* generic/tclExecute.c: Corrections to the NO_WIDE_TYPE build. Also
	added missing "break" to a switch that broke wide XOR operations.

2005-10-10  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* generic/tclInterp.c (DeleteScriptLimitCallback)
	(SetScriptLimitCallback): Improve the interlocking between the script
	limit callback record and the hash table of current such records, to
	prevent crashes in callbacks that create callbacks.
	(Tcl_LimitSetTime): Reset the correct flag. Problem reported by
	Nicolas Castagne <castagne@imag.fr> on comp.lang.tcl

2005-10-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c: Fixing errors in last commit. (Two commits,
	the second removes wrong comment).

2005-10-09  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclBasic.c:
	* generic/tclExecute.c:
	* generic/tclStrToD.c:
	* generic/tclStringObj.c: Initialise variables to avoid compiler
	warnings ([Bug 1320818] among others).

2005-10-08  Don Porter  <dgp@users.sourceforge.net>

	TIP#237 IMPLEMENTATION

	[kennykb-numerics-branch] Resynchronized with the HEAD; at this
	checkpoint [-rkennykb-numerics-branch-20051008], the HEAD and
	kennykb-numerics-branch contain identical code.

	[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  <dgp@users.sourceforge.net>

	[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  <jeffh@ActiveState.com>

	* 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  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

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

2005-10-05  Don Porter  <dgp@users.sourceforge.net>

	[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  <andreask@activestate.com>

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

	* doc/CrtChannel.3: Fixed [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 [Bug 1286256].

2005-10-05  Jeff Hobbs  <jeffh@ActiveState.com>

	* 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  <dgp@users.sourceforge.net>

	[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  <jeffh@ActiveState.com>

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

	* tests/http.test:              do not URI encode -._~ according
	* library/http/http.tcl (init): to RFC3986. [Bug 1182373] (aho)

	* unix/tclLoadShl.c (TclpDlopen): use DYNAMIC_PATH on second shl_load
	only. [Bug 1204237]

	* doc/scan.n: scan %[] requires "one or more chars" [Bug 1277503]

	* 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  <vasiljevic@users.sourceforge.net>

	* 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  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

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

	* generic/tclInt.h:	Added new routine TclGetNumberFromObj to
	* generic/tclObj.c:	provide efficient access to the actual
	internal rep of a numeric Tcl_Obj without conversions.

2005-10-03  Kevin Kenny  <kennykb@acm.org>

	* tools/loadICU.tcl:  Changed the file names of message catalogs to
			      lowercase.
	* tools/makeTestCases.tcl:
	* library/tzdata/*:   Olson's tzdata2005n.tar.gz. Includes new DST
			      rules for USA and a number of changes to other
			      locales.
	* tests/clock.test:   Regenerated for new US DST rules.

2005-09-30  Don Porter  <dgp@users.sourceforge.net>

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

2005-09-30  Don Porter  <dgp@users.sourceforge.net>

	[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  <jeffh@ActiveState.com>

	* 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  <dgp@users.sourceforge.net>

	[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  <donal.k.fellows@manchester.ac.uk>

	* 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  <kennykb@acm.org>

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

2005-09-26  Kevin Kenny  <kennykb@acm.org>

	* libtommath/:                   Updated to release 0.36.
	* 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  <dgp@users.sourceforge.net>

	[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].

2005-09-20  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	Revise TclIncrObj() to call
	Tcl_GetBignumAndClearObj.

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

2005-09-16  Don Porter  <dgp@users.sourceforge.net>

	[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  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* 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  <dgp@users.sourceforge.net>

	* 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().

	formatting rules.

2005-09-13  Don Porter  <dgp@users.sourceforge.net>

	* 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/StringObj.3:

2005-09-12  Don Porter  <dgp@users.sourceforge.net>

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

	* generic/tclCmdAH.c:		Added support for the "ll" width

	* 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  <andreask@activestate.com>

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

2005-09-09  Kevin Kenny  <kennykb@acm.org>

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

2005-09-09  Don Porter  <dgp@users.sourceforge.net>

	* 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  <donal.k.fellows@manchester.ac.uk>

	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  <dgp@users.sourceforge.net>

	* 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  <donal.k.fellows@man.ac.uk>

	* 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  <donal.k.fellows@man.ac.uk>

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

2005-09-02  Don Porter  <dgp@users.sourceforge.net>

	[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  <andreask@activestate.com>

2005-09-01  Don Porter  <dgp@users.sourceforge.net>

	[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  <vincentdarley@sourceforge.net>

	* 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  <dgp@users.sourceforge.net>

	[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  <andreask@activestate.com>

	* library/tm.tcl (::tcl::tm::roots): Accepted Don Porter's patch for

2005-08-29  Kevin Kenny  <kennykb@acm.org>

	* generic/tclBasic.c (ExprMathFunc): Restored "round away from zero"
	* tests/expr.test (expr-46.*):       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  <andreask@activestate.com>

	* 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  <donal.k.fellows@man.ac.uk>

	* 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  <donal.k.fellows@man.ac.uk>

	* 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.

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

	* generic/tclExecute.c: Corrected some TRACE bugs that prevented
	compilation with --enable-symbols=all.

	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.

2005-08-24  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* 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.

2005-08-23  Mo DeJong  <mdejong@users.sourceforge.net>

	* unix/configure.in:

	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.)

	does not include any trailing whitespace.

2005-08-17  Don Porter  <dgp@users.sourceforge.net>

	[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  <dgp@users.sourceforge.net>

	[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  <dgp@users.sourceforge.net>

	[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  <dgp@users.sourceforge.net>

	[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  <dgp@users.sourceforge.net>

	[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  <dgp@users.sourceforge.net>

	[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.

2005-08-12  Kevin Kenny  <kennykb@acm.org>

	* 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  <dgp@users.sourceforge.net>

	[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.

2005-08-11  Kevin Kenny  <kennykb@acm.org>

	* 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 specific
	* unix/configure:              data without USE_THREAD_STORAGE and
	* unix/tcl.m4:                 radically refactored the code for
	* unix/tclConfig.h.in:         USE_THREAD_STORAGE so that it has fewer
	* unix/tclUnixThrd.c:          dependencies on the order of
	* win/configure:               finalization. (Also, made 'make
	* win/Makefile.in:             distclean' on Windows clean just a
	* win/rules.vc:                little bit cleaner.)
	* win/tcl.m4:
	* win/tclWinThrd.c:

2005-08-10  Don Porter  <dgp@users.sourceforge.net>

	[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  <kennykb@acm.org>

	* 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  <vincentdarley@users.sourceforge.net>

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

2005-08-08  Don Porter  <dgp@users.sourceforge.net>

	[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  <donal.k.fellows@man.ac.uk>

	* 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  <dgp@users.sourceforge.net>

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

2005-08-05  Donal K. Fellows  <dkf@users.sf.net>

	* 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  <kennykb@users.sourceforge.net>

	* win/makefile.vc: Removed unused file ldAout.tcl.
	* win/makefile.bc: [Bug 1244361]

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

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

2005-08-04  Andreas Kupries  <andreask@activestate.com>

	* 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  <dgp@users.sourceforge.net>

	[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  <dgp@users.sourceforge.net>

	* generic/tclCompExpr.c:	Untangled some dependencies in the
	* generic/tclEvent.c:		order of finalization routines.
	* generic/tclInt.h:		[Bug 1251399]
	* generic/tclObj.c:

2005-08-02  Don Porter	<dgp@users.sourceforge.net>

	[kennykb-numerics-branch] Updated from HEAD

2005-07-30  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tclLoadDyld.c (TclpDlopen, TclpLoadMemory): workarounds for
	bugs/changes in behaviour in Mac OS X 10.4 Tiger.

2005-07-29  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclCmdIL.c (InfoGlobalsCmd): Even in high-speed mode, still
	have to take care with non-existant variables. [Bug 1247135]

2005-07-28  Mo DeJong  <mdejong@users.sourceforge.net>

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

2005-07-28  Don Porter	<dgp@users.sourceforge.net>

	* 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  <dkf@users.sf.net>

	* 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	<dgp@users.sourceforge.net>

	* 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  <mdejong@users.sourceforge.net>

	* 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	<dgp@users.sourceforge.net>

	* 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  <mdejong@users.sourceforge.net>

	* 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. [Bug 1160114]
	[Patch 1244153]

2005-07-23  Don Porter	<dgp@users.sourceforge.net>

	* library/auto.tcl:	Updates to the Tcl script library to make use
	* library/history.tcl:	of Tcl 8.4 features. Forward port of
	* library/init.tcl:	appropriate portions of [Patch 1237755].
	* library/package.tcl:
	* library/safe.tcl:
	* library/word.tcl:

2005-07-23  Mo DeJong  <mdejong@users.sourceforge.net>

	* tests/string.test: Add string is tests for functionality that was
	not tested.
	* win/README: Update msys + mingw URL. Remove old Cygwin + mingw
	info.

2005-07-23  Miguel Sofer  <msofer@users.sf.net>

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

2005-07-23  Donal K. Fellows  <dkf@users.sf.net>

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

2005-07-21  Donal K. Fellows  <dkf@users.sf.net>

	* 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  <kennykb@acm.org>

	* 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.

2005-07-16  Kevin B. Kenny  <kennykb@acm.org>

	* generic/tclStrToD.c (RefineResult):  Plugged a stupid memory leak in
	RefineResult (called from Tcl_StrToD). [Tk Bug 1227781]

2005-07-15  Kevin B. Kenny  <kennykb@acm.org>

	* 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  <donal.k.fellows@manchester.ac.uk>

	* 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	<dgp@users.sourceforge.net>

	* unix/tclUnixSock.c:	Use a ProcessGlobalValue to store the value
	* win/tclWinSock.c:	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  <kennykb@acm.org>

	[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  <dkf@users.sf.net>

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

2005-07-11  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclExecute.c: General style cleanup.

2005-07-08  Mo DeJong  <mdejong@users.sourceforge.net>

	* 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	<dgp@users.sourceforge.net>

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

2005-07-05  Don Porter	<dgp@users.sourceforge.net>

	* 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  <dkf@users.sf.net>

	* 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  <vasiljevic@users.sourceforge.net>

	* 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  <mdejong@users.sourceforge.net>

	* 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.

2005-06-24  Kevin Kenny  <kennykb@acm.org>

	* 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	<dgp@users.sourceforge.net>

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

2005-06-23  Kevin Kenny  <kennykb@acm.org>

	* 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  <das@users.sourceforge.net>

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

2005-06-22  Don Porter	<dgp@users.sourceforge.net>

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

2005-06-22  Kevin Kenny  <kennykb@acm.org>

	* 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  <andreask@activestate.com>

	* 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  <kennykb@acm.org>

	* 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	<dgp@users.sourceforge.net>

	* 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  <dkf@users.sf.net>

	* 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  <dkf@users.sf.net>

	* 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  <mdejong@users.sourceforge.net>

	* 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  <das@users.sourceforge.net>

	* 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  <donal.k.fellows@man.ac.uk>

2005-06-17  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclTimer.c (AfterDelay): Split out the code to manage
	synchronous-delay [after] commands.

	[after] did not mix well... [Bug 1221395]

2005-06-14  Donal K. Fellows  <dkf@users.sf.net>

	* 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  <vincentdarley@users.sourceforge.net>

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

2005-06-12  Donal K. Fellows  <dkf@users.sf.net>

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

2005-06-10  Donal K. Fellows  <dkf@users.sf.net>

	* 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  <vincentdarley@users.sourceforge.net>

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

	mention of distinctly-relevant [namespace path] subcommand.

2005-06-07  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclInt.h:		Reduced the Tcl_ObjTypes "index",
	* generic/tclIndexObj.c:	"ensembleCmd", "localVarName", and

2005-06-07  Donal K. Fellows  <dkf@users.sf.net>

	* generic/tclIO.c (Tcl_ChannelTruncateProc): Stop proliferation of

	* 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

	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  <kennykb@acm.org>

	* 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	<jeffh@ActiveState.com>

	*** 8.5a3 TAGGED FOR RELEASE ***

	when multiple Tcl source dirs exist.

2005-06-01  Don Porter	<dgp@users.sourceforge.net>

	* 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  <donal.k.fellows@man.ac.uk>

	* 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  <donal.k.fellows@man.ac.uk>

	* 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  <vasiljevic@users.sourceforge.net>

	* 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 [Bug 1082283].

2005-05-30  Zoran Vasiljevic  <vasiljevic@users.sf.net>

	* win/tclWinThrd.c: Fixed [Bug 1204064]

2005-05-30  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	TIP #229 IMPLEMENTATION

	* generic/tclNamesp.c (Tcl_FindCommand, TclResetShadowedCmdRefs)

2005-05-26  Daniel Steffen  <das@users.sourceforge.net>

	* 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	<jeffh@ActiveState.com>

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

2005-05-25  Don Porter	<dgp@users.sourceforge.net>

	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	<dgp@users.sourceforge.net>

	* 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  <das@users.sourceforge.net>

	* 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	<dgp@users.sourceforge.net>

	* 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  <dkf@users.sf.net>

	* 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  <das@users.sourceforge.net>

	* 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	<dgp@users.sourceforge.net>

	* 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	<dgp@users.sourceforge.net>

	* 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  <kennykb@users.sourceforge.net>

	* 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  <das@users.sourceforge.net>

	* 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 during
	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:
	* unix/tclUnixInit.c: fixed gcc 4.0 warnings.

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

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

2005-05-13  Kevin Kenny  <kennykb@acm.org>

	* 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	<dgp@users.sourceforge.net>

	* 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  <kennykb@acm.org>

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

2005-05-11  Kevin Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch] Resynchronized with the HEAD; at this
	checkpoint [-rkennykb-numerics-branch-20050511], the HEAD and
	kennykb-numerics-branch contain identical code.

2005-05-11  Kevin Kenny  <kennykb@acm.org>

	* 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	<jeffh@ActiveState.com>

	* 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]
	* generic/tclCmdMZ.c (Tcl_StringObjCmd): add extra checks to prevent
	possible UMR in unichar cmp function for string map.

2005-05-10  Kevin Kenny  <kennykb@acm.org>

	* generic/tclBinary.c (FormatNumber): Fixed a bug where NaN's 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.
	* libtommath/tommath_superclass.h: Corrected C++-style comment.

2005-05-10  Kevin Kenny  <kennykb@acm.org>

	Merged all changes on kennykb-numerics-branch back into the HEAD.
	TIP's 132 and 232 are now Final.

2005-05-10  Miguel Sofer  <msofer@users.sf.net>

	* generic/tclExecute.c (ExponLong, ExponWide):
	* tests/expr.test (expr-23.34/35): fixed special case 'i**0' for i>0
	[Bug 1198892]

2005-05-09  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]
	* win/tclWin32Dll.c (TclpCheckStackSpace, TclWinCPUID): Reworked
	structured event handling to function even with
	-fomit-frame-pointers.

2005-05-08  Kevin B. Kenny  <kennykb@acm.org>

	[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.

2005-05-07  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]
	* generic/tclEvent.c:  Moved initialization of tclStrToD.c's
	* 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	<jeffh@ActiveState.com>

	* unix/tcl.m4, unix/configure: correct Solaris 10 (5.10) check and add
	support for x86_64 Solaris cc builds.

2005-05-05  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch] Merged with HEAD.

	* generic/tclUtil.c:
	* generic/tclIntDecls.h:	`make genstubs`
	* generic/tclStubInit.c:
	* generic/tclBasic.c:	Added callers of TclMatchIsTrivial where
	* generic/tclCmdIL.c:	a search can be done more efficiently
	* generic/tclCompCmds.c:when it is recognized that a pattern match
	* generic/tclDictObj.c:	is really an exact match. [Patch 1076088]
	* generic/tclIO.c:
	* generic/tclNamesp.c:
	* generic/tclVar.c:

	* generic/tclCompCmds.c:	Factored common efficiency trick into
	a macro named CompileWord.

	* generic/tclCompCmds.c:	Replaced all instance of
	* generic/tclCompile.c:		TCL_OUT_LINE_COMPILE with TCL_ERROR.
	* generic/tclInt.h:		Now that we've eradicated the mistaken
	* tests/appendComp.test:	notion of a "compile-time error", we
	can use the TCL_ERROR return code to signal any failure to produce
	bytecode.

2005-05-03  Don Porter	<dgp@users.sourceforge.net>

	* doc/DString.3:	Eliminated use of identifier "string" in Tcl's

2005-04-26  Kevin B. Kenny  <kennykb@users.sourceforge.net>

	* 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 @PLAT_SRCS@ 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	<dgp@users.sourceforge.net>

	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].
	* tests/string.test:	Test string-23.0 for Bug 1187123.

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

2005-04-21  Don Porter	<dgp@users.sourceforge.net>

	* 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.

	* tests/clock.test (clock-48.1): Added regression test for the above
	bug.
	Thanks to Ulrich Ring for reporting this bug.

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

2005-04-16  Zoran Vasiljevic  <vasiljevic@users.sf.net>

	* 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 [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.

	with TCL_COMPILE_DEBUG.

2005-04-13  David Gravereaux  <davygrvy@pobox.com>

	* generic/tclIO.c (Tcl_SetChannelBufferSize): Lowest size limit
	* tests/io.test:	changed from ten bytes to one byte. Need for
	* tests/iogt.test:	this change was proven by Ross Cartlidge
	<rossc@cisco.com> 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	<dgp@users.sourceforge.net>

	* 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.

	an example and mentioned the use of [file copy].
	* doc/fconfigure.n: Improved documentation of -encoding binary option.
	This is all following comments from Steve Manning <steve@manning.net>
	on comp.lang.tcl that the current documentation was not clear.

2005-04-13  Miguel Sofer  <msofer@users.sf.net>

	* 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	<dgp@users.sourceforge.net>

	* 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.

	* generic/tclUtil.c (Tcl_PrintDouble): Changed the signature of
	TclDoubleDigits so that it accepts a pointer to the signum of the

	code to handle IEEE signed zeroes in Tcl_DoubleDigits. (It can't be

	to ensure that 'ldexp' is never called with a value that will
	underflow.
	* tests/expr.test: Added tests for the smallest representible value,
	and rounding between it and zero. (The tests reflect current
	behaviour; plan is to change the specification of Tcl so that input
	conversion of doubles underflows silently.)

2005-02-02  Mo DeJong  <mdejong@users.sourceforge.net>

	* generic/tclProc.c (TclInitCompiledLocals): Add check for type of the
	framePtr->procPtr->bodyPtr passed to TclInitCompiledLocals and panic
	if it is not the correct type. If the body of the proc is not of the
	compiled byte code type then the code will crash. This was discovered
	while tracking down a crash in Itcl, that crash is fixed by Itcl patch
	1115085.

	New scanning function for extracting 'double' from a string that
	rounds correctly, and handles denormals and infinities.
	* unix/Makefile.in:
	* win/Makefile.in:
	* win/makefile.vc:
	Added tclStrToD.c and the tommath routines that support it.

	These changes represent a partial implementation of TIP #132.
	Output conversion of floating point numbers, and proper handling
	of infinities within expressions, still need to be addressed.
