Tcl Source Code

2011-08-30  Donal K. Fellows  <[email protected]>

	* generic/tclInterp.c (SlaveCommandLimitCmd, SlaveTimeLimitCmd):
	[Bug 3398794]: Ensure that low-level conditions in the limit API are
	enforced at the script level through errors, not a Tcl_Panic. This
	means that interpreters cannot read their own limits (writing already
	did not work).

2011-08-30  Reinhard Max  <[email protected]>

	* unix/tclUnixSock.c (TcpWatchProc): [Bug 3394732]: Put back the check
	for server sockets.

2011-08-29  Don Porter  <[email protected]>

	* generic/tclIORTrans.c: Leak of ReflectedTransformMap.

2011-08-27  Don Porter  <[email protected]>

	* generic/tclStringObj.c:  [RFE 3396731]: Revise the [string reverse]
	* tests/string.test:	implementation to operate on the representation
	that comes in, avoid conversion to other reps.

2011-08-23  Don Porter  <[email protected]>

	* generic/tclIORChan.c:	[Bug 3396948]: Leak of ReflectedChannelMap.

2011-08-19  Don Porter  <[email protected]>

	* generic/tclIORTrans.c: [Bugs 3393279, 3393280]: ReflectClose(.) is
	missing Tcl_EventuallyFree() calls at some of its exits.

	* generic/tclIO.c: [Bugs 3394654, 3393276]: Revise FlushChannel() to
	account for the possibility that the ChanWrite() call might recycle
	the buffer out from under us.

	* generic/tclIO.c: Preserve the chanPtr during FlushChannel so that
	channel drivers don't yank it away before we're done with it.

2011-08-19  Alexandre Ferrieux  <[email protected]>

	* generic/tclTest.c: [Bug 2981154]: async-4.3 segfault.
	* tests/async.test:  [Bug 1774689]: async-4.3 sometimes fails.

2011-08-18  Alexandre Ferrieux  <[email protected]>

	* generic/tclIO.c: [Bug 3096275]: Sync fcopy buffers input.

2011-08-18  Jan Nijtmans  <[email protected]>

	* generic/tclUniData.c: [Bug 3393714]: Overflow in toupper delta
	* tools/uniParse.tcl
	* tests/utf.test

2011-08-17  Alexandre Ferrieux  <[email protected]>

	* generic/tclIO.c:  [Bug 2946474]: Consistently resume backgrounded
	* tests/ioCmd.test: flushes+closes when exiting.

2011-08-17  Alexandre Ferrieux  <[email protected]>

	* doc/interp.n: Document TIP 378's one-way-ness.

2011-08-17  Don Porter  <[email protected]>

	* generic/tclGet.c: [Bug 3393150]: Overlooked free of intreps.
	(It matters for bignums!)

2011-08-16  Don Porter  <[email protected]>

	* generic/tclCompile.c: [Bug 3392070]: More complete prevention of
	Tcl_Obj reference cycles when producing an intrep of ByteCode.

2011-08-16  Donal K. Fellows  <[email protected]>

	* generic/tclListObj.c (TclLindexList, TclLsetFlat): Silence warnings
	about (unreachable) cases of uninitialized variables.
	* generic/tclCmdIL.c (SelectObjFromSublist): Improve the generation of

	labels.

2011-08-04  Reinhard Max  <[email protected]>

	* generic/tclIOSock.c (TclCreateSocketAddress): Don't bother using
	AI_ADDRCONFIG for now, as it was causing problems in various
	situations.

2011-08-04  Donal K. Fellows  <[email protected]>

	* generic/tclAssembly.c (AssembleOneLine, GetBooleanOperand)
	(GetIntegerOperand, GetListIndexOperand, FindLocalVar): [Bug 3384840]:
	A Tcl_Obj is allocated by GetNextOperand, so callers of it must not
	hold a reference to one in the 'out' parameter when calling it. This
	was causing a great many memory leaks.

	* generic/tclTomMathDecls.h:
	* macosx/Tcl.xcode/project.pbxproj:
	* macosx/Tcl.xcodeproj/project.pbxproj:
	* tests/util.test:
	* unix/Makefile.in:
	* win/Makefile.in:
	* win/Makefile.vc:
	[Bug 3349507]: Fix a bug where bignum->double conversion is "round up"
	and not "round to nearest" (causing expr double(1[string repeat 0 23])
	not to be 1e+23).

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

	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.

	error codes (TclOO miscellany).

	* generic/tclCmdAH.c, generic/tclCmdIL.c: More generation of error
	codes (miscellaneous commands mostly already handled).

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

	* README:	[Bug 3202030]: Updated README files, repairing broken
	* macosx/README:URLs and removing other bits that were clearly wrong.
	* unix/README:	Still could use more eyeballs on the detailed build
	* win/README:	advice on various plaforms.

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

	* library/init.tcl (tcl::mathfunc::rmmadwiw): Disable by default to
	make test suite work.

	* generic/tclBasic.c, generic/tclStringObj.c, generic/tclTimer.c,

2011-03-09  Donal K. Fellows  <[email protected]>

	* tests/incr.test: Update more of the test suite to use Tcltest 2.

2011-03-09  Don Porter  <[email protected]>

	* generic/tclNamesp.c:	[Bug 3202171]: Tighten the detector of nested
	* tests/namespace.test:	[namespace code] quoting that the quoted
	scripts function properly even in a namespace that contains a custom
	"namespace" command.

	* doc/tclvars.n:	Formatting fix.  Thanks to Pat Thotys.

2011-03-09  Donal K. Fellows  <[email protected]>

	* tests/dstring.test, tests/init.test, tests/link.test: Update more of
	the test suite to use Tcltest 2.

	and unsigned integer expressions

2011-03-08  Don Porter  <[email protected]>

	* generic/tclInt.h:	Remove TclMarkList() routine, an experimental
	* generic/tclUtil.c:	dead-end from the 8.5 alpha days.

	* generic/tclResult.c (ResetObjResult): [Bug 3202905]: Correct failure
	to clear invalid intrep.  Thanks to Colin McDonald.

2011-03-08  Donal K. Fellows  <[email protected]>

	* generic/tclAssembly.c, tests/assemble.test: Migrate to use a style
	more consistent with the rest of Tcl.

2011-03-06  Don Porter  <[email protected]>

	* generic/tclBasic.c:	More replacements of Tcl_UtfBackslash() calls

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

	* generic/tclExecute.c (TclStackFree): insure that the execStack
	satisfies "at most one free stack after the current one" when
	consecutive reallocs caused the creation of intervening stacks.
