* * generic/tclStringObj.c: Rewrite GrowStringBuffer() so that itdgp2009-02-181-0/+7
| | | | | | | | has parallel structure with GrowUnicodeBuffer(). The revision permits allocation attempts to continue all the way up to failure, with no gap. It also directly manipulates the String and Tcl_Obj internals instead of inefficiently operating via Tcl_*SetObjLength() with all of its extra protections and underdocumented special cases.
* * generic/tclStringObj.c: Another round of simplification ondgp2009-02-181-0/+5
| | | | the allocation macros.
* * generic/tclStringObj.c: Pare back the length of the unicodedgp2009-02-171-0/+7
| | | | | | | | array in a non-extended String struct to one Tcl_UniChar, meant to hold the terminating NUL character. Non-empty unicode strings are then stored by extending the String struct by stringPtr->maxChars additional slots in that array with sizeof(Tcl_UniChar) bytes per slot. This revision makes the allocation macros much simpler.
* * generic/tclStringObj.c: Factor out common GrowUnicodeBuffer()dgp2009-02-171-0/+3
| | | | and solve overflow and growth algorithm fallbacks in it.
* * win/tcl.m4, win/configure: Check if cl groks _WIN64 already tohobbs2009-02-171-0/+6
| | | | | avoid CC manipulation that can screw up later configure checks. Use 'd'ebug runtime in 64-bit builds.
* * generic/tclStringObj.c: Factor out common GrowStringBuffer().dgp2009-02-171-0/+11
| | | | | | | | | | | * generic/tclStringObj.c: Convert Tcl_AppendStringsToObj into * tests/stringObj.test: a radically simpler implementation where we just loop over calls to Tcl_AppendToObj. This fixes [Bug 2597185]. It also creates a *** POTENTIAL INCOMPATIBILITY *** in that T_ASTO can now allocate more space than is strictly required, like all the other Tcl_Append* routines. The incompatibility was detected by test stringObj-6.5, which I've updated to reflect the new behavior.
* * generic/tclStringObj.c: Revise buffer growth implementationdgp2009-02-171-8/+14
| | | | | | | in ExtendStringRepWithUnicode. Use cheap checks to determine that no reallocation is necessary without cost of computing the precise number of bytes needed. Also make use of the string growth algortihm in the case of repeated appends.

| | | | | * tests/stringObj.test: command with [teststringobj maxchars] and update the tests.
* * generic/tclStringObj.c: Added protections from invalid memorydgp2009-02-161-0/+6
| | | | | | | * generic/tclTestObj.c: accesses when we append (some part of) * tests/stringObj.test: a Tcl_Obj to itself. Added the appendself and appendself2 subcommands to the [teststringobj] testing command and added tests to the test suite. [Bug 2603158]

| | | | Tcl_AppendObjToObj.
* * generic/tclStringObj.c: Replace the 'size_t uallocated' fielddgp2009-02-151-0/+7
| | | | | | | | of the String struct, storing the number of bytes allocated to store the Tcl_UniChar array, with an 'int maxChars' field, storing the number of Tcl_UniChars that may be stored in the allocated space. This reduces memory requirement a small bit, and makes some range checks simpler to code.
* * generic/tclStringObj.c: Removed limitation indgp2009-02-151-0/+9
| | | | | | | | 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 creatingdgp2009-02-141-0/+11
| | | | | | | | | | | | 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 unicodedgp2009-02-131-0/+3

* * generic/tclStringObj.c: Rewrites of the routinesdgp2009-02-131-0/+10
| | | | | | | | | | | 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 bydgp2009-02-121-0/+5
| | | | | | * 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 AppendUtfToUnicodeRepdgp2009-02-121-0/+7
| | | | | | 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.
