These improve encoded channel + conversion speeds by up to 20%. + + * tests/split.test: added 1-char string split tests + * generic/tclCmdMZ.c (Tcl_SplitObjCmd): Use TclUtfToUniChar. + Also added a special case for single-ascii-char splits. + (Tcl_StringObjCmd): Use TclUtfToUniChar. + For STR_RANGE, support getting ranges of ByteArrays (reverts + change from 2000-05-26). + (TraceExecutionProc) add proper static declaration. + + * generic/tclInt.h: add macro version of Tcl_UtfToUniChar + (TclUtfToUniChar) that does the one-byte utf-char check without + calling Tcl_UtfToUniChar, for use by the core. This brings + notable speedups for primarily ascii string handling. + + * generic/tcl.h (TCL_PATCH_LEVEL): bump to 8.4.1.1 for patchlevel + only. This interim number will only be reflected by + [info patchlevel]. + 2002-11-11 Kevin Kenny <kennykb@acm.org> * doc/Tcl.n: Corrected indentation of the new language. Oops. |
