Fellows <[email protected]> * generic/tclCompCmdsSZ.c (TclSubstCompile): Improved the sequence of instructions issued for [subst] when dealing with simple variable references. 2012-11-13 Miguel Sofer <[email protected]> * generic/tclCmdAH.c (CatchObjCmdCallback): Do not decrRefCount the newValuePtr sent to Tcl_ObjSetVar2: TOSV2 is 'fire and forget', it decrs on its own. Fix for [Bug 3595576], found by andrewsh. 2012-12-13 Jan Nijtmans <[email protected]> * generic/tcl.h: Fix Tcl_DecrRefCount macro such that it doesn't access its objPtr parameter twice any more. 2012-12-10 Donal K. Fellows <[email protected]> * tools/tcltk-man2html.tcl (plus-pkgs): Increased robustness of version number detection code to deal with packages whose names are prefixes of other packages. * unix/Makefile.in (dist): Added pkgs/package.list.txt to distribution |
