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.

	* 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.

	(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

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

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.

	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

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

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

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

	* 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/tclOOCall.c (TclOODeleteContext, TclOOGetCallContext):

the standard setting will provide a relative line number for the
command \fBsomecode\fR and the relevant frame will be of type
\fBeval\fR. With frame-debug active on the other hand the tracking
extends so far that the system will be able to determine the file and
absolute line number of this command, and return a frame of type
\fBsource\fR. This more exact information is paid for with slower
execution of all commands.
.PP
Note that once it is on, this flag cannot be switched back off: such
attempts are silently ignored. This is needed to maintain the
consistency of the underlying interpreter's state.
.RE
.TP
\fBinterp\fR \fBdelete \fR?\fIpath ...?\fR
.
Deletes zero or more interpreters given by the optional \fIpath\fR
arguments, and for each interpreter, it also deletes its slaves. The
command also deletes the slave command for each interpreter deleted.
