Tcl Source Code

2013-04-23  Jan Nijtmans  <[email protected]>

	* generic/tclDecls.h: Implement Tcl_NewBooleanObj, Tcl_DbNewBooleanObj
	and Tcl_SetBooleanObj as macros using Tcl_NewIntObj, Tcl_DbNewLongObj
	and Tcl_SetIntObj. Starting with Tcl 8.5, this is exactly the same,
	it only eliminates code duplication.
	* generic/tclInt.h: Eliminate use of NO_WIDE_TYPE everywhere: It's
	exactly the same as TCL_WIDE_INT_IS_LONG

2013-04-19  Jan Nijtmans  <[email protected]>

	* generic/tclDecls.h: Implement many Tcl_*Var* functions and
	Tcl_GetIndexFromObj as (faster/stack-saving) macros around resp
	their Tcl_*Var*2 equivalent and Tcl_GetIndexFromObjStruct.

2013-04-12  Jan Nijtmans  <[email protected]>

	* generic/tclDecls.h: Implement Tcl_Pkg* functions as
	(faster/stack-saving) macros around Tcl_Pkg*Ex functions.

2013-04-08  Don Porter  <[email protected]>

	* generic/regc_color.c:	[Bug 3610026] Stop crash when the number of
	* generic/regerrs.h:	"colors" in a regular expression overflows
	* generic/regex.h:	a short int.  Thanks to Heikki Linnakangas
	* generic/regguts.h:	for the report and the patch.
