Tcl Source Code

2012-02-09  Don Porter  <[email protected]>

	* generic/tclStringObj.c:	Converted the memcpy() calls in 
	append operations to memmove() calls.  This adds safety in the case
	of overlapping copies, and improves performance on some benchmarks.

2012-02-06  Don Porter  <[email protected]>

	* generic/tclEnsemble.c: [Bug 3485022] TclCompileEnsemble() avoid
	* tests/trace.test:	compile when exec traces set.

2012-02-06  Miguel Sofer  <[email protected]>

	* generic/tclTrace.c:  Fix for [Bug 3484621]: insure that
	* tests/trace.test:    execution traces on bytecoded commands bump
	the interp's compile epoch.

	* generic/tclUniData.c: [Frq 3464401] Support Unicode 6.1
	* generic/regc_locale.c:

2012-02-02  Don Porter  <[email protected]>

	* win/tclWinFile.c:	[Bugs 2974459,2879351,1951574,1852572,
	1661378,1613456]: Revisions to the NativeAccess() routine that
	queries file permissions on Windows native filesystems.  Meant to
	fix numerous bugs where [file writable|readable|executable] "lies"
	about what operations are possible, especially when the file resides
	on a Samba share.

2012-02-01  Donal K. Fellows  <[email protected]>

	* doc/AddErrInfo.3: [Bug 3482614]: Documentation nit.

2012-01-30  Donal K. Fellows  <[email protected]>

	* generic/tclOO.c (Tcl_CopyObjectInstance): [Bug 3474460]: When
	copying an object, make sure that the configuration of the variable
	resolver is also duplicated.

2012-01-22  Jan Nijtmans  <[email protected]>

	* tools/uniClass.tcl:    [FRQ 3473670]: Various Unicode-related
	* tools/uniParse.tcl:    speedups/robustness. Enhanced tools to
	* generic/tclUniData.c:  be able to handle characters > 0xffff
	* generic/tclUtf.c:      Done in all branches in order to simplify
	* generic/regc_locale.c: merges for new Unicode versions (such as 6.1)

2012-01-22  Donal K. Fellows  <[email protected]>

	* generic/tclDictObj.c (DictExistsCmd): [Bug 3475264]: Ensure that
	errors only ever happen when insufficient arguments are supplied, and
	not when a path doesn't exist or a dictionary is poorly formatted (the
	two cases can't be easily distinguished).

	* tools/uniParse.tcl:    [Bug 3444754]: string tolower \u01c5 is wrong
	* generic/tclUniData.c:
	* tests/utf.test:

2011-11-30  Jan Nijtmans  <[email protected]>

	* library/tcltest/tcltest.tcl: [Bug 967195]: Make tcltest work
	when tclsh is compiled without using the setargv() function on mingw.
	(no need to incr the version, since 2.2.10 is never released)

2011-11-29  Jan Nijtmans  <[email protected]>

	* win/Makefile.in: don't install tommath_(super)?class.h
	* unix/Makefile.in: don't install directories like 8.2 and 8.3
	* generic/tclTomMath.h: [Bug 2991415]: move include tclInt.h from
	* generic/tclTomMathInt.h: tclTomMath.h to tclTomMathInt.h

	* generic/tclCompCmds.c (TclCompileDictWithCmd): Corrected handling of
	qualified names, and added spacial cases for empty bodies (used when
	[dict with] is just used for extracting variables).

2011-10-07  Jan Nijtmans  <[email protected]>

	* generic/tcl.h:        Fix gcc warnings (discovered with
	* generic/tclIORChan.c: latest mingw, based on gcc 4.6.1)
	* tests/env.test:       Fix env.test, when running
	under wine 1.3

2011-10-06  Donal K. Fellows  <[email protected]>

	* generic/tclDictObj.c (TclDictWithInit, TclDictWithFinish):
	* generic/tclCompCmds.c (TclCompileDictWithCmd): Experimental
	compilation for the [dict with] subcommand, using parts factored out
	from the interpreted version of the command.

	make the main [file] command hidden by default in safe interpreters,
	because that's what existing code expects. This will reduce the amount
	which the code breaks, but not necessarily eliminate it...

2011-09-23  Don Porter  <[email protected]>

	* generic/tclIORTrans.c: More revisions to get finalization of
	ReflectedTransforms correct, including adopting a "dead" field as
	was done in tclIORChan.c.

	* tests/thread.test:	Stop using the deprecated thread management
	commands of the tcltest package.  The test suite ought to provide
	these tools for itself.  They do not belong in a testing harness.

2011-09-22  Don Porter  <[email protected]>

	* tools/tcltk-man2html-utils.tcl (process-text): Teach the HTML
	generator how to handle this magic.

2011-09-21  Don Porter  <[email protected]>

	* generic/tclThreadTest.c: Revise the thread exit handling of the
	[testthread] command so that it properly maintains the per-process
	data structures even when the thread exits for reasons other than
	the [testthread exit] command.

2011-09-21  Alexandre Ferrieux  <[email protected]>

	* unix/tclIO.c: [Bug 3412487]: Now short reads are allowed in
	synchronous fcopy, avoid mistaking them as nonblocking ones.

2011-09-21  Andreas Kupries  <[email protected]>

	* generic/tclCompExpr.c: [Bug 3408408]: Partial improvement by sharing
	as literals the computed values of constant subexpressions when we can
	do so without incurring the cost of string rep generation.

2011-09-13  Don Porter  <[email protected]>

	* generic/tclUtil.c:	[Bug 3390638]: Workaround broken solaris
	studio cc optimizer.  Thanks to Wolfgang S. Kechel.

	* generic/tclDTrace.d:	[Bug 3405652]: Portability workaround for
	broken system DTrace support.  Thanks to Dagobert Michelson.

2011-09-12  Jan Nijtmans  <[email protected]>

	* win/tclWinPort.h: [Bug 3407070]: tclPosixStr.c won't build with
	EOVERFLOW==E2BIG

2011-09-11  Don Porter  <[email protected]>

	* tests/thread.test:	Convert [testthread] use to Thread package
	use in thread-6.1.  Eliminates a memory leak in `make valgrind`.

	* tests/socket.test:	[Bug 3390699]: Convert [testthread] use to
	Thread package use in socket_*-13.1.  Eliminates a memory leak in
	`make valgrind`.

2011-09-09  Don Porter  <[email protected]>

	* README:

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

2011-07-15  Don Porter  <[email protected]>

	* generic/tclCompile.c: Avoid segfaults when RecordByteCodeStats()
	is called in a deleted interp.

	* generic/tclCompile.c:	[Bug 467523, 3357771]: Prevent circular
	references in values with ByteCode intreps.  They can lead to
	memory leaks.

2011-07-14  Donal K. Fellows  <[email protected]>

	* generic/tclOOCall.c (TclOORenderCallChain): [Bug 3365156]: Remove
	stray refcount bump that caused a memory leak.

2011-07-12  Don Porter  <[email protected]>

2011-06-28  Reinhard Max  <[email protected]>

	* unix/tclUnixSock.c (CreateClientSocket): [Bug 3325339]: Fix and
	simplify posting of the writable fileevent at the end of an
	asynchronous connection attempt. Improve comments for some of the
	trickery around [socket -async].

	* tests/socket.test: Adjust tests to the async code changes. Add
	more tests for corner cases of async sockets.

2011-06-22  Andreas Kupries  <[email protected]>

	* library/platform/pkgIndex.tcl: Updated to platform 1.0.10. Added
	* library/platform/platform.tcl: handling of the DEB_HOST_MULTIARCH
	* unix/Makefile.in: location change for libc.
	* win/Makefile.in:

	* generic/tclInt.h: Fixed the inadvertently committed disabling of
	  stack checks, see my 2010-11-15 commit.

2011-06-22  Reinhard Max  <[email protected]>

	Merge from rmax-ipv6-branch:
	* unix/tclUnixSock.c: Fix [socket -async], so that all addresses
	returned by getaddrinfo() are tried, not just the first one. This
	requires the event loop to be running while the async connection
	is in progress. ***POTENTIAL INCOMPATIBILITY***
	* tests/socket.test: Add a test for the above.
	* doc/socket: Document the fact that -async needs the event loop
	* generic/tclIOSock.c: AI_ADDRCONFIG is broken on HP-UX

2011-06-21  Don Porter  <[email protected]>

	* generic/tclLink.c:	[Bug 3317466]: Prevent multiple links to a
	single Tcl variable when calling Tcl_LinkVar().

2011-06-13  Don Porter  <[email protected]>

	* generic/tclStrToD.c:  [Bug 3315098]: Mem leak fix from Gustaf Neumann.

2011-06-08  Andreas Kupries  <[email protected]>

	* generic/tclExecute.c: Reverted the fix for [Bug 3274728]
	committed on 2011-04-06 and replaced with one which is
	64bit-safe. The existing fix crashed tclsh on Windows 64bit.

2011-06-08  Donal K. Fellows  <[email protected]>

	* tests/fileSystem.test: Reduce the amount of use of duplication of
	complex code to perform common tests, and convert others to do the
	test result check directly using Tcltest's own primitives.

2011-06-06  Jan Nijtmans  <[email protected]>

	* tests/socket.test: Add test constraint, so 6.2 and 6.3 don't fail
	when the machine does not have support for ip6. Follow-up to checkin
	from 2011-05-11 by rmax.

2011-06-02  Don Porter  <[email protected]>

	* generic/tclBasic.c:	Removed TclCleanupLiteralTable(), and old
	* generic/tclInt.h:	band-aid routine put in place while a fix
	* generic/tclLiteral.c:	for [Bug 994838] took shape.  No longer needed.

2011-06-02  Donal K. Fellows  <[email protected]>

	* generic/tclInt.h (TclInvalidateNsCmdLookup): [Bug 3185407]: Extend
	the set of epochs that are potentially bumped when a command is
	created, for a slight performance drop (in some circumstances) and
	improved semantics.

2011-06-01  Miguel Sofer  <[email protected]>

	* generic/tclBasic.c: Using the two free data elements in NRCommand to
	store objc and objv - useful for debugging.

2011-06-01  Jan Nijtmans  <[email protected]>

	* generic/tclUtil.c:   Fix for [Bug 3309871]: Valgrind finds:
	invalid read in TclMaxListLength()

2011-05-31  Don Porter  <[email protected]>

	* generic/tclInt.h:	Use a complete growth algorithm for lists
	* generic/tclListObj.c:	so that length limits do not overconstrain
	* generic/tclStringObj.c:	by a factor of 2.  [Bug 3293874]:
	* generic/tclUtil.c:	Fix includes rooting all growth routines
	by default on a commone tunable parameter TCL_MIN_GROWTH.

2011-05-25  Don Porter  <[email protected]>

	* library/msgcat/msgcat.tcl:	Bump to msgcat 1.4.4.
	* library/msgcat/pkgIndex.tcl:
	* unix/Makefile.in
	* win/Makefile.in

	* library/msgcat/msgcat.tcl (msgcat::mcset, msgcat::mcmset): Remove
	some useless code; [dict set] builds dictionary levels for us.

2011-05-17  Andreas Kupries  <[email protected]>

	* generic/tclCompile.c (TclFixupForwardJump): Tracked down and fixed
	* generic/tclBasic.c (TclArgumentBCEnter): the cause of a violation
	of my assertion that 'ePtr->nline == objc' in TclArgumentBCEnter.
	When a bytecode was grown during jump fixup the pc -> command line
	mapping was not updated. When things aligned just wrong the mapping
	would direct command A to the data for command B, with a different
	number of arguments.

2011-05-11  Reinhard Max  <[email protected]>

	* unix/tclUnixSock.c (TcpWatchProc): No need to check for server
	sockets here, as the generic server code already takes care of
	that.
	* tests/socket.test (accept): Add tests to make sure that this
	remains so.

2011-05-10  Don Porter  <[email protected]>

	* generic/tclInt.h:     New internal routines TclScanElement() and
	* generic/tclUtil.c:    TclConvertElement() are rewritten guts of
	machinery to produce string rep of lists.  The new routines avoid
	and correct [Bug 3173086].  See comments for much more detail.

	* generic/tclDictObj.c:         Update all callers.
	* generic/tclIndexObj.c:
	* generic/tclListObj.c:
	* generic/tclUtil.c:
	* tests/list.test:

2011-05-07  Donal K. Fellows  <[email protected]>

	* generic/tclLoad.c (TclGetLoadedPackages): Convert to use Tcl_Obj API
	for result generation.

2011-05-07  Miguel Sofer  <[email protected]>

	* generic/tclInt.h: fix USE_TCLALLOC so that it can be enabled
	* unix/Makefile.in: without editing the Makefile

2011-05-05  Don Porter  <[email protected]>

	* generic/tclListObj.c:	Stop generating string rep of dict when
	converting to list.  Tolerate NULL interps more completely.

2011-05-03  Don Porter  <[email protected]>

	* generic/tclUtil.c:	Tighten Tcl_SplitList().
	* generic/tclListObj.c:	Tighten SetListFromAny().
	* generic/tclDictObj.c:	Tighten SetDictFromAny().
	* tests/join.test:
	* tests/mathop.test:

2011-05-02  Don Porter  <[email protected]>

	* generic/tclCmdMZ.c:	Revised TclFindElement() interface.  The
	* generic/tclDictObj.c:	final argument had been bracePtr, the address
	* generic/tclListObj.c:	of a boolean var, where the caller can be told
	* generic/tclParse.c:	whether or not the parsed list element was
	* generic/tclUtil.c:	enclosed in braces.  In practice, no callers
	really care about that.  What the callers really want to know is
	whether the list element value exists as a literal substring of the
	string being parsed, or whether a call to TclCopyAndCollpase() is
	needed to produce the list element value.  Now the final argument
	is changed to do what callers actually need.  This is a better fit
	for the calls in tclParse.c, where now a good deal of post-processing
	checking for "naked backslashes" is no longer necessary.
	***POTENTIAL INCOMPATIBILITY***
	For any callers calling in via the internal stubs table who really
	do use the final argument explicitly to check for the enclosing brace
	scenario.  Simply looking for the braces where they must be is the
	revision available to those callers, and it will backport cleanly.

	* tests/parse.test:	Tests for expanded literals quoting detection.

	* generic/tclCompCmdsSZ.c:	New TclFindElement() is also a better
	fit for the [switch] compiler.

	* generic/tclInt.h:	Replace TclCountSpaceRuns() with
	* generic/tclListObj.c:	TclMaxListLength() which is the function we
	* generic/tclUtil.c:	actually want.
	* generic/tclCompCmdsSZ.c:

	* generic/tclCompCmdsSZ.c: Rewrite of parts of the switch compiler to
	better use the powers of TclFindElement() and do less parsing on
	its own.

2011-04-28  Don Porter  <[email protected]>

	* generic/tclInt.h:	New utility routines:
	* generic/tclParse.c:	TclIsSpaceProc() and
	* generic/tclUtil.c:	TclCountSpaceRuns()

	* generic/tclCmdMZ.c:	Use new routines to replace calls to
	* generic/tclListObj.c:	isspace() and their /* INTL */ risk.
	* generic/tclStrToD.c:
	* generic/tclUtf.c:
	* unix/tclUnixFile.c:

	* generic/tclStringObj.c:	Improved reaction to out of memory.

2011-04-27  Don Porter  <[email protected]>

2011-04-18  Don Porter  <[email protected]>

	* generic/tclCmdIL.c:	Use ListRepPtr(.) and other cleanup.
	* generic/tclConfig.c:
	* generic/tclListObj.c:

	* generic/tclInt.h:	Define and use macros that test whether
	* generic/tclBasic.c:	a Tcl list value is canonical.
	* generic/tclUtil.c:

2011-04-18  Donal K. Fellows  <[email protected]>

	* doc/dict.n: [Bug 3288696]: Command summary was confusingly wrong
	when it came to [dict filter] with a 'value' filter.

	* generic/tclGetDate.y, generic/tclDate.c (TclClockOldscanObjCmd):
	More generation of errorCode information.

2011-03-28  Donal K. Fellows  <[email protected]>

	* generic/tclCmdMZ.c, generic/tclConfig.c, generic/tclUtil.c: More
	generation of errorCode information, notably when lists are
	mis-parsed.

	* generic/tclCmdMZ.c (Tcl_RegexpObjCmd, Tcl_RegsubObjCmd): Use the
	error messages generated by the variable management code rather than
	creating our own.

2011-03-27  Miguel Sofer  <[email protected]>

	* generic/tclBasic.c (TclNREvalObjEx): fix performance issue,
	notably apparent in tclbench's "LIST lset foreach". Many thanks to
	twylite for patiently researching the issue and explaining it to
	me: a missing Tcl_ResetObjResult that causes unwanted sharing of
	the current result Tcl_Obj.

2011-03-26  Donal K. Fellows  <[email protected]>

	* generic/tclNamesp.c (Tcl_Export, Tcl_Import, DoImport): More
	generation of errorCode information.

	* generic/tclCompExpr.c, generic/tclCompile.c, generic/tclExecute.c:

2011-03-16  Jan Nijtmans  <[email protected]>

	* generic/tclCkalloc.c: [Bug 3197864]: Pointer truncation on Win64
	TCL_MEM_DEBUG builds.

2011-03-16  Don Porter  <[email protected]>

	* generic/tclBasic.c:	Some rewrites to eliminate calls to
	* generic/tclParse.c:	isspace() and their /* INTL */ risk.
	* generic/tclProc.c:

2011-03-16  Jan Nijtmans  <[email protected]>

	* unix/tcl.m4:    Make SHLIB_LD_LIBS='${LIBS}' the default and
	* unix/configure: set to "" on per-platform necessary basis.
	Backported from TEA, but kept all original platform code which was

	* generic/tclAssembly.c (new file):
	* generic/tclBasic.c (Tcl_CreateInterp):
	* generic/tclInt.h:
	* tests/assemble.test (new file):
	* unix/Makefile.in:
	* win/Makefile.in:
	* win/makefile.vc:  Merged dogeen-assembler-branch into HEAD.
	Since all functional changes are in the tcl::unsupported namespace,
	there's no reason to sequester this code on a separate branch.

2011-03-05  Miguel Sofer  <[email protected]>

	* generic/tclExecute.c: cleaner mem management for TEBCdata

	* generic/tclExecute.c:
	* tests/nre.test: Renamed BottomData to TEBCdata, so that the name
	refers to what it is rather than to its storage location.

	* generic/tclBasic.c:     Renamed struct TEOV_callback to
	* generic/tclCompExpr.c:  the more descriptive NRE_callback.
	* generic/tclCompile.c:
	* generic/tclExecute.c:
	* generic/tclInt.decls:
	* generic/tclInt.h:
	* generic/tclIntDecls.h:

2011-03-04  Donal K. Fellows  <[email protected]>

	* generic/tclOOMethod.c (ProcedureMethodCompiledVarConnect)
	(ProcedureMethodCompiledVarDelete): [Bug 3185009]: Keep references to
	resolved object variables so that an unset doesn't leave any dangling
	pointers for code to trip over.

2011-03-01  Miguel Sofer  <[email protected]>

	* generic/tclBasic.c (TclNREvalObjv): missing a variable
	declaration in commented out non-optimised code, left for ref in
	checkin [b97b771b6d]

2011-03-03  Don Porter  <[email protected]>

	* generic/tclResult.c (Tcl_AppendResultVA):	Use the directive
	USE_INTERP_RESULT [TIP 330] to force compat with interp->result
	access, instead of the improvised hack USE_DIRECT_INTERP_RESULT_ACCESS
	from releases past.

	* generic/tclExecute.c (ExprObjCallback): Fix object leak

	* generic/tclExecute.c (TEBCresume): Store local var array and
	constants in automatic vars to reduce indirection, slight perf
	increase

	* generic/tclOOCall.c (TclOODeleteContext): Added missing '*' so
	that trunk compiles.

	* generic/tclBasic.c (TclNRRunCallbacks): [Patch 3168229]: Don't do
	the trampoline dance for commands that do not have an nreProc.

2011-03-01  Donal K. Fellows  <[email protected]>

	* generic/tclOO.c (Tcl_NewObjectInstance, TclNRNewObjectInstance)

	* win/configure:      (autoconf-2.59)
	* win/tclWin32Dll.c:  VS 2005 64-bit does not have intrin.h, and
	* generic/tclPanic.c: does not need it.

2011-01-07  Kevin B. Kenny  <[email protected]>

	* tests/util.test (util-15.*): Added test cases for floating point
	conversion of the largest denormal and the smallest normal number,
	to avoid any possibility of the failure suffered by PHP in the
	last couple of days. (They didn't fail, so no actual functional
	change.)

2011-01-05  Donal K. Fellows  <[email protected]>

	* tests/package.test, tests/pkg.test: Coalesce these tests into one
	file that is concerned with the package system. Convert to use
	tcltest2 properly.
	* tests/autoMkindex.test, tests/pkgMkIndex.test: Convert to use

	* generic/tclPanic.c:    Restore abort() as it was before.
	* win/tclWinFile.c:      [Patch 3124554]: Use ExitProcess() here, like
	in wish.

	* win/tclWinSock.c (CreateSocket):         Swap the loops over
	* unix/tclUnixSock.c (CreateClientSocket): local and remote addresses,
	so that the system's address preference for the remote side decides
	which family gets tried first. Cleanup and clarify some of the
	comments.

2010-12-13  Jan Nijtmans  <[email protected]>

	* generic/tcl.h:    [Bug 3135271]: Link error due to hidden
	* unix/tcl.m4:      symbols (CentOS 4.2)
	* unix/configure:   (autoconf-2.59)

	used by Tk_Main. See [Patch 3124554]: Move WishPanic from Tk to Tcl

2010-12-12  Stuart Cassoff  <[email protected]>

	* unix/tcl.m4: Better building on OpenBSD.
	* unix/configure: (autoconf-2.59)
