* | | * generic/tclStringObj.c: Removed limitation indgp2009-02-151-12/+7
| | | | | | | | | | | | | | | | | | | | | | | | Tcl_AppendObjToObj where the char length of the result was only computed if the appended string was all single byte characters. This limitation was in place to dodge a bug in Tcl_GetUniChar. With that bug gone, we can take advantage of always recording the length of append results when we know it.
* | | * generic/tclStringObj.c: Revisions so that we avoid creatingdgp2009-02-141-51/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the strange representation of an empty string with objPtr->bytes == NULL and stringPtr->hasUnicode == 0. Instead in the situations where that was being created, create a traditional two-legged stork representation (objPtr->bytes = tclEmptyStringRep and stringPtr->hasUnicode = 1). In the situations where the strange rep was treated differently, continue to do so by testing stringPtr->numChars == 0 to detect it. These changes make the code more conventional so easier for new maintainers to pick up. Also sets up further simplifications.

* | | New utility routine UnicodeLength(), to compute the length of unicodedgp2009-02-131-23/+21
| | | | | | | | | | | | | | | buffer arguments when no length is passed in, with built-in overflow protection included. Update three callers to use it.
* | | * generic/tclStringObj.c: Rewrites of the routinesdgp2009-02-131-152/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tcl_GetCharLength, Tcl_GetUniChar, Tcl_GetUnicodeFromObj, Tcl_GetRange, and TclStringObjReverse to use the new macro, and to more simply and clearly split the cases depending on whether a valid unicode rep is present or needs to be created. * generic/tclInt.h: New macro TclNumUtfChars meant to be a faster replacement for a full Tcl_NumUtfChars() call when the string has all single-byte characters.
* | | * generic/tclStringObj.c: Simplified Tcl_GetCharLength bydgp2009-02-121-24/+25
| | | | | | | | | | | | | | | | | | * generic/tclTestObj.c: removing code that did nothing. Added early returns from Tcl_*SetObjLength when the desired length is already present; adapted test command to the change.
* | | * generic/tclStringObj.c: Re-implemented AppendUtfToUnicodeRepdgp2009-02-121-32/+49
| | | | | | | | | | | | | | | | | | so that we no longer pass through Tcl_DStrings which have their own sets of problems when lengths overflow the int range. Now AUTUR and FillUnicodeRep share a common core routine.
