	[kennykb_numerics_branch]


	* 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  Kevin Kenny  <[email protected]>

	[kennykb_numerics_branch]
	
	* generic/tclCmdMZ.c (Tcl_StringObjCmd):
	* generic/tclInt.h:
	* generic/tclObj.c (Tcl_GetBooleanFromObj, SetDoubleFromAny,
	Tcl_GetLongFromObj, Tcl_GetWideIntFromObj, Tcl_GetBignumFromObj):
	* generic/tclParseExpr.c (GetLexeme):
	* generic/tclScan.c (Tcl_ScanObjCmd):
................................................................................
	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  <[email protected]>

	[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:	here and there.
	* generic/tclObj.c:
	* generic/tclStrToD.c:
	* generic/tclUtil.c:

2005-08-22  Don Porter  <[email protected]>

	[kennykb_numerics_branch]

	* generic/tclInt.h:	New ACCEPT_NAN macro to mark code that supports
	* generic/tclCmdAH.c:	or disables accepting of the NaN value at 
	* generic/tclExecute.c:	various points.
	* generic/tclLink.c:

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

	* tests/expr.test:	Corrected the wideIs64bit constraint.
	* tests/format.test:
	* tests/scan.test:

2005-08-21  Don Porter  <[email protected]>

	[kennykb_numerics_branch]

	* generic/tclUtil.c:

	* generic/tclInt.decls:	Moved TclExprFloatError to tclBasic.c and
	* generic/tclBasic.c:	made it static.
................................................................................
	* generic/tclStrToD.c:	Disabled out of date support "hack" for errno.

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

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

	[kennykb_numerics_branch]

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

	* generic/tclProc.c:	Wrapped a few tclWideIntType uses in 
................................................................................
	* generic/tclStubInit.c:

	* generic/tclCmdIL.c:	Rework Tcl_IncrObjCmd and the INST_*INCR*
	* generic/tclExecute.c:	opcodes to use the new routines.

2005-08-18  Don Porter  <[email protected]>

	[kennykb_numerics_branch]

	* generic/tclExecute.c:

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

	[kennykb_numerics_branch]

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

	[kennykb_numerics_branch]

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

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

	[kennykb_numerics_branch]

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

	* tests/scan.test:	Making << bignum-aware means that repeated
	* tests/string.test:	left shifting cannot turn a positive into
	a negative.  Revised [int_range] and [largest_int] utility commands
................................................................................
	* generic/tclTomMath.h:	Added mp_or and mp_xor to routines from
	* unix/Makefile.in:	libtommath used by Tcl.
	* win/Makefile.in:
	* win/makefile.vc:

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

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

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

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

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

	[kennykb_numerics_branch]

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

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

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

	[kennykb_numerics_branch]

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

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

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

	[kennykb_numerics_branch]

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

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

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

	[kennykb_numerics_branch]

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

	* generic/tclStrToD.c:	Restored conditional generation of
................................................................................
	* win/Makefile.in:             'make distclean' on Windows clean
	* win/rules.vc:                just a little bit cleaner.)
	* win/tcl.m4:
	* win/tclWinThrd.c:
	
2005-08-10  Don Porter  <[email protected]>

	[kennykb_numerics_branch]

	* generic/tclTomMath.h:	Added mp_shrink, mp_to_unsigned_bin,
	* unix/Makefile.in:	mp_to_unsigned_bin_n, and mp_unsigned_bin_size

	code path reported on comp.lang.tcl.

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

	[kennykb_numerics_branch]

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

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

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

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

	[kennykb_numerics_branch]
	* generic/tclObj.c:	Rewrote Tcl_GetDoubleFromObj().

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

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

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

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

	[kennykb_numerics_branch] Updated from HEAD

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

	* generic/tclObj.c:	Simplified routines that manage the typeTable.
	Deleted the UpdateStringOfBoolean() routine, that can never be called.
................................................................................
	* 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	<[email protected]>

	[kennykb_numerics_branch] Updated from HEAD

2005-07-30  Daniel Steffen  <[email protected]>

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

2005-07-29  Donal K. Fellows  <[email protected]>
................................................................................
	* win/tclWinSock.c:	value returned by Tcl_GetHostName()
	([info hostname]).  Also re-order initialization of the value
	on Windows to favor GetComputerName() over gethostname() as
	a source of the information.

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

	[kennykb_numerics_branch] Updated from HEAD

	* generic/tclCmdMZ.c (Tcl_StringObjCmd):
	* generic/tclInt.h:
	* generic/tclObj.c (Tcl_GetDoubleFromObj, SetDoubleFromAny,
	                    Tcl_GetIntFromObj, SetIntOrWideFromAny):
	* generic/tclStrToD.c (TclParseNumber, etc.):
	* tclTomMathInterface.c (TclBNInitBignumFromWideUInt):

	[kennykb-numerics-branch]

	* generic/tclExecute.c: Corrected some TRACE bugs that prevented
	compilation with --enable-symbols=all.
	* generic/tclStrToD.c: Revised commentary to prepare for a
	renaming of the file, removed some dead code, and fixed a bug
	where TclBignumToDouble failed on huge negative numbers.
	* tests/binary.test (binary-65.*): Added missing 'ieeeFloatingPoint' to
	large/small significand tests.
	* tests/expr.test (expr-45.*) Added missing braces around expressions.
	
2005-08-24  Don Porter  <[email protected]>


	[kennykb-numerics-branch]

	* 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  Kevin Kenny  <[email protected]>

	[kennykb-numerics-branch]
	
	* generic/tclCmdMZ.c (Tcl_StringObjCmd):
	* generic/tclInt.h:
	* generic/tclObj.c (Tcl_GetBooleanFromObj, SetDoubleFromAny,
	Tcl_GetLongFromObj, Tcl_GetWideIntFromObj, Tcl_GetBignumFromObj):
	* generic/tclParseExpr.c (GetLexeme):
	* generic/tclScan.c (Tcl_ScanObjCmd):
................................................................................
	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  <[email protected]>

	[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:	here and there.
	* generic/tclObj.c:
	* generic/tclStrToD.c:

2005-08-22  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclInt.h:	New ACCEPT_NAN macro to mark code that supports
	* generic/tclCmdAH.c:	or disables accepting of the NaN value at 
	* generic/tclExecute.c:	various points.
	* generic/tclLink.c:

	* 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. 
................................................................................
	* generic/tclParseExpr.c: Reworked parsing of numbers to call
	TclParseNumber rather than trying to do things locally.
	* generic/tclStrToD.c: Corrected a comment. Changed so that
	*endPtrPtr does not include any trailing whitespace.
	
2005-08-17  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

	* generic/tclExecute.c:	New routine TclIncrObj to centralize the

	INST_DICT_INCR_IMM to make use of it.

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

	[kennykb-numerics-branch]

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

	* tests/scan.test:	Making << bignum-aware means that repeated
	* tests/string.test:	left shifting cannot turn a positive into
	a negative.  Revised [int_range] and [largest_int] utility commands
................................................................................
	* generic/tclTomMath.h:	Added mp_or and mp_xor to routines from
	* unix/Makefile.in:	libtommath used by Tcl.

	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/tclStubInit.c:

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

	[kennykb-numerics-branch]

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

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

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

	[kennykb-numerics-branch]

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

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

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

	[kennykb-numerics-branch]

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

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

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

	[kennykb-numerics-branch]

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

	* generic/tclStrToD.c:	Restored conditional generation of
................................................................................
	* win/Makefile.in:             'make distclean' on Windows clean
	* win/rules.vc:                just a little bit cleaner.)
	* win/tcl.m4:
	* win/tclWinThrd.c:
	
2005-08-10  Don Porter  <[email protected]>

	[kennykb-numerics-branch]

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

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

	[kennykb-numerics-branch]

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

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

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

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

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

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

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

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

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

	[kennykb-numerics-branch] Updated from HEAD

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

	* generic/tclObj.c:	Simplified routines that manage the typeTable.
	Deleted the UpdateStringOfBoolean() routine, that can never be called.
................................................................................
	* 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	<[email protected]>

2005-07-29  Donal K. Fellows  <[email protected]>
................................................................................
	* win/tclWinSock.c:	value returned by Tcl_GetHostName()
	([info hostname]).  Also re-order initialization of the value
	on Windows to favor GetComputerName() over gethostname() as
	a source of the information.

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

	[kennykb-numerics-branch] Updated from HEAD

	* generic/tclCmdMZ.c (Tcl_StringObjCmd):
	* generic/tclInt.h:

	                    Tcl_GetIntFromObj, SetIntOrWideFromAny):
	* generic/tclStrToD.c (TclParseNumber, etc.):
	* tclTomMathInterface.c (TclBNInitBignumFromWideUInt):

Changes to generic/tclExecute.c.
