Tcl Source Code

2011-08-07  Donal K. Fellows  <[email protected]>

	* generic/tclOOInfo.c (InfoClassCallCmd): [Bug 3387082]: Plug memory
	leak in call chain introspection.

2011-08-06  Kevin B, Kenny  <[email protected]>

	* generic/tclAssemnbly.c: [Bug 3384840]: Plug another memory leak.
	* generic/tclStrToD.c: [Bug 3386975]: Plug another memory leak.

2011-08-05  Kevin B. Kenny  <[email protected]>

	* generic/tclStrToD.c: [Bug 3386975]: Plugged a memory leak in
	double->string conversion.

2011-08-05  Don Porter  <[email protected]>

	*** 8.6b2 TAGGED FOR RELEASE ***

	* changes:	Updates for 8.6b2 release.

2011-08-05  Donal K. Fellows  <[email protected]>

	* generic/tclAssembly.c (AssembleOneLine): Ensure that memory isn't
	leaked when an unknown instruction is encountered. Also simplify code
	through use of Tcl_ObjPrintf in error message generation.

	* generic/tclZlib.c (ZlibTransformClose): [Bug 3386197]: Plug a memory
	leak found by Miguel with valgrind, and ensure that the correct
	direction's buffers are released.

2011-08-04  Miguel Sofer  <[email protected]>

	* generic/tclVar.c (TclPtrSetVar): Fix valgrind-detected error when
	newValuePtr is the interp's result obj.

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

	* generic/tclAssembly.c (FreeAssemblyEnv): [Bug 3384840]: Plug another
	possible memory leak due to over-complex code for freeing the table 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.
	* tests/assemble.test (assemble-51.*): Added group of memory leak
	tests.

2011-08-02  Don Porter  <[email protected]>

	* changes:	Updates for 8.6b2 release.
	* tools/tcltk-man2html.tcl: Variable substitution botch.

2011-08-02  Donal K. Fellows  <[email protected]>

	* generic/tclObj.c (Tcl_DbIncrRefCount, Tcl_DbDecrRefCount)
	(Tcl_DbIsShared): [Bug 3384007]: Fix the panic messages so they share
	what should be shared and have the right number of spaces.

2011-08-01  Miguel Sofer  <[email protected]>

	* tools/tcltk-man2html-utils.tcl (output-IP-list, cross-reference):
	Update to generation to produce proper HTML bulleted and enumerated
	lists.

2011-07-19 Alexandre Ferrieux  <[email protected]>

	* doc/upvar.n: Undocument long gone limitation of [upvar].

2011-07-18  Don Porter  <[email protected]>

	* generic/tcl.h:	Bump version number to 8.6b2.
	* library/init.tcl:
	* unix/configure.in:
	* win/configure.in:
	* unix/tcl.spec:
	* tools/tcl.wse.in:
	* 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

2011-07-08  Donal K. Fellows  <[email protected]>

	* doc/http.n: [FRQ 3358415]: State what RFC defines HTTP/1.1.

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

	* generic/tclBasic.c: Add missing INT2PTR

2011-07-03  Donal K. Fellows  <[email protected]>

	* doc/FileSystem.3: Corrected statements about ctime field of 'struct
	stat'; that was always the time of the last metadata change, not the
	time of creation.
