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]

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 the Tcl 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/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>

	[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 [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  <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]

	-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.

	                      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

	* 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>

	* 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].
	* generic/tclObj.c:

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:

	* generic/tclDecls.h:	make genstubs
	* generic/tclStubInit.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  Miguel Sofer <msofer@users.sf.net>

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

2005-09-15  Don Porter  <dgp@users.sourceforge.net>

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().
	* 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  <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/SetResult.3:
	* 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:	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 <andreask@activestate.com>

	* 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  <dgp@users.sourceforge.net>

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

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>

	* 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  <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 [Tcl SF Bug 1189657]. Syncs the implementation to the
	  specification (TIP #189).

2005-08-29  Don Porter  <dgp@users.sourceforge.net>

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

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

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

	* 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 <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.

2005-08-25  Don Porter  <dgp@users.sourceforge.net>

	[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.

	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.

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:
	* win/configure: Regen.

	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.)

2005-08-23  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch]

	* generic/tclStrToD.c:	Bug fix: set shift magnitude properly whether
	we're expanding to mp_int type or not.

	* generic/tclExecute.c:	Bug fix: ACCEPT_NAN under INST_UMINUS.

	* generic/tclStrToD.c:	New macros TIP_114_FORMATS and KILL_OCTAL to

	* generic/tclExecute.c:	various points.
	* generic/tclLink.c:

	* generic/tclInt.h:	New internal routine TclSetBignumIntRep
	* generic/tclObj.c:	consolidates packing of bignum value into

	errno to zero in OldMathFuncProc.

2005-08-19  Don Porter  <dgp@users.sourceforge.net>

	[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/tclExecute.c:

2005-08-17  George Peter Staplin <GeorgePS@XMission.com>

	* 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  <kennykb@acm.org>

	* 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  <kennykb@users.sourceforge.net>

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

	[kennykb-numerics-branch]

	* generic/tclTomMath.h:	Added mp_shrink, mp_to_unsigned_bin,

	* 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,

2005-08-04  Don Porter  <dgp@users.sourceforge.net>

	[kennykb-numerics-branch] Updated from HEAD

	* generic/tclObj.c:	Rewrote Tcl_GetBooleanFromObj() and supporting

	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.

	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.
	[Tcl bug 1160114]
	[Tcl patch 1244153]

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

	* library/auto.tcl:	Updates to the Tcl script library to make
	* library/history.tcl:	use 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
	* 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  <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>

	* 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  <dkf@users.sf.net>

	* 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  <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]

2005-06-09  Donal K. Fellows  <dkf@users.sf.net>

	* 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	<dgp@users.sourceforge.net>

	* 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/tclStubInit.c:

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
	* generic/tclIndexObj.c (Tcl_WrongNumArgs):    messages from ensembles

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]

	confusion 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

	* 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 Tcl Bug #1082283.

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/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 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:
	* 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

	* 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.

	* 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

	* generic/tclUtil.c:	Extended TclGetIntForIndex to recognize
	index formats including end+integer and integer+/-integer.

	* generic/tclCmdMZ.c:	Extended the -start switch of [regexp]
	and [regsub] to accept all index formats known by TclGetIntForIndex.

	* tests/ioCmd.test:

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.

2005-04-25  Kevin B. Kenny  <kennykb@users.sourceforge.net>

	* doc/CrtMathFunc.n:		Revised documentation for TIP 232

2005-04-25  Daniel Steffen  <das@users.sourceforge.net>

	* 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:

	* 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.

2005-04-19  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclBasic.c:	Added unsupported command
	* generic/tclCmdAH.c:	[::tcl::unsupported::EncodingDirs] to permit
	* generic/tclInt.h:	query/set of the encoding search path at
	* generic/tclInterp.c:	the script level.  Updated init.tcl to make
	* library/init.tcl:	use of the new command.	 Also updated several
	coding practices in init.tcl ("eq" for [string equal], etc.)

2005-04-19  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.tcl (Initialize): Put initialization code into a
	proc to avoid inadvertently clobbering global variables.
	[Bug 1185933]
	* tests/clock.test (clock-48.1): Added regression test for the
	above bug.
	Thanks to Ulrich Ring for reporting this bug.

2005-04-16  Miguel Sofer <msofer@users.sf.net>

	* 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 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  Don Porter	<dgp@users.sourceforge.net>

	* tests/unixInit.test:	Disabled obsolete tests and removed code
	* tests/encoding.test:	that supported them.
	* generic/tclInterp.c:

	* library/init.tcl:	Use auto-loading to bring in Tcl Module
	* library/tclIndex:	support as needed.  This reduces startup
	* library/tm.tcl:	time by delaying this initialization to
	a later time.

2005-04-15  Miguel Sofer <msofer@users.sf.net>

	* generic/tclExecute.c: missing semicolons caused failure to
	compile 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
	* tests/iogt.test:	for 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.

2005-04-13  Kevin B. Kenny  <kennykb@acm.org>

	* library/clock.n: Added a missing '--' on several [switch]
	commands to improve performance of [clock format] and related
	operations.  [Feature Request 1182459]

2005-04-13  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* doc/fcopy.n: Improved documentation on copying binary files,
	added 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.  [Bug 1177363]

2005-04-12  Kevin B. Kenny  <kennykb@acm.org>

	* compat/strstr.c: Added default definition of NULL to
	accommodate building on systems with badly broken headers.
	[Bug #1175161]

2005-04-11  Donal K. Fellows  <donal.k.fellows@manchester.ac.uk>

	* tools/tclZIC.tcl: Rewrote to take advantage of more features of
	Tcl 8.5 (on which it was dependent anyway). Also added a [package
	require] line to formalize the relationship.

	[kennykb-numerics-branch] Merged with HEAD. Updated to libtommath 0.35.

	* generic/tclBasic.c: Attempted to repeat changes that applied
	to tclExecute.c in Miguel Sofer's commit of 2005-04-01, together
	with (possibly) a few more uses of his new object creation macros.
	Also plugged a memory leak in TclObjInvoke. [Bug 1180368]

	* generic/tclCmdAH.c (Tcl_EncodingObjCmd):	Updated to call

	* doc/re_syntax.n: Change some uses of .TP to .IP to work around
	bugs in various *roff implementations. Also reworded the atom
	descriptions slightly.

2005-04-05  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c (ExprSrandFunc): Replaced incursions into the

	with simpler calls of Tcl_GetIntFromObj and Tcl_GetLongFromObj,
	now that those routines are better behaved wrt shimmering.

	* generic/tclIntDecls.h:
	* generic/tclListObj.c:
	* generic/tclStubInit.c:
	* generic/tclVar.c: Changed the internal representation of lists
	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/tclInt.h:
	* 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

2005-03-31  Miguel Sofer <msofer@users.sf.net>

	been done as part of the 1115904 bug fix on 2005-03-18.

	* generic/tclThreadTest.c:	Stop providing the phony package
	"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	<dgp@users.sourceforge.net>

	* generic/tclCompCmds.c (TclCompileIncrCmd):	Corrected checks
	for immediate operand usage to permit leading space and sign
	characters.  Restores more efficient bytecode for [incr x -1]
	that got lost in the CONST string reforms of Tcl 8.4.  [Bug 1165671]

	* generic/tclStrToD.c (TclStrToD, SafeLdExp):
	    Added code to manage the FPU precision on gcc+x86.
	    Enabled fast conversion of floats with small exponents
	    now that precision is correct.
	* tests/expr.test: Corrected test for the smallest representible
	    value to the right IEEE values.

2005-02-06  David N. Welton  <davidw@dedasys.com>

	* doc/Thread.3: One-word grammar fix.

2005-02-05  David N. Welton  <davidw@dedasys.com>

	* doc/Thread.3: Fixed sentence describing flags for
	Tcl_CreateThread.

	* doc/FileSystem.3: Cleaned up typo in Tcl_FSNewNativePath
	documentation.

	* generic/tclPathObj.c: Cleaned up typo in comment.

2005-02-03  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]

	* generic/tclStrToD.c (TclStrToD, RefineResult, SafeLdExp):
	    Added code 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.

2005-02-01  Kevin B. Kenny  <kennykb@acm.org>

	[kennykb-numerics-branch]  Merged with HEAD as of today.

	* generic/tclInt.decls:
	    Changed numbers of new stubs to resolve a conflict.
	* generic/tclInt.h:
	    Added new TclStrToD routine that replaces the native
	    'strtod' thro
	ughout Tcl.
	* generic/tclCmdMZ (Tcl_StringObjCmd):
	* generic/tclGet.c (Tcl_GetDouble):
	* generic/tclObj.c (SetBooleanFromAny, SetDoubleFromAny):
	* generic/tclParseExpr.c (GetLexeme):
	* generic/tclScan.c (Tcl_ScanObjCmd):
	    Replaced all uses of the native 'strtod' with a TclStrToD
	    routine that performs correct rounding and handles denormals.
	* generic/tclStrToD.c: (new file)
	    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.

2005-02-01  Don Porter	<dgp@users.sourceforge.net>

	* generic/tclExecute.c (TclCompEvalObj): Removed stray statement
	left behind in prior code reorganization.

2005-01-31  Don Porter	<dgp@users.sourceforge.net>

	* unix/configure:	autoconf-2.57

2005-01-30  Joe English	 <jenglish@users.sourceforge.net>

	* unix/configure.in: Restored two double-evals that were
	removed in the DBGX purge; these are still needed on some
	platforms to account for TCL_TRIM_DOTS.	 [Bug 1112654]

	* unix/configure: NOT REGENERATED: only have autoconf 2.59 here,
	need to find someone with autoconf 2.57.

2005-01-28  Jeff Hobbs	<jeffh@ActiveState.com>

	* unix/configure, unix/tcl.m4: add solaris 64-bit gcc build
	support. [Bug 1021871]

2005-01-25  Daniel Steffen  <das@users.sourceforge.net>

	* unix/tcl.m4 (Darwin): fixed bug with static build linking to

	* generic/tclThread.c: Typo police. Fixed some nits
	* generic/tclCmdAH.c:  in header comments of functions.

	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.
