| | | | | | | | | | | | | | * generic/tclInt.h: * generic/tclBasic.c: * generic/tclExecute.c: * generic/tclNamesp.c (Tcl_PopCallFrame): Rewritten tailcall implementation, ::unsupported::atProcExit is (temporarily?) gone. The new approach is much simpler, and also closer to being correct. This commit fixes [Bug 2649975] and [Bug 2695587]. * tests/coroutine.test: Moved the tests to their own files, * tests/tailcall.test: removed the unsupported.test. Added * tests/unsupported.test: tests for the fixed bugs.

* * generic/tclStringObj.c: Several revisions to the shimmeringdgp2009-02-221-17/+65
| | | | | | | | | | | | | patterns between Unicode and UTF string reps. Most notably the call: objPtr = Tcl_NewUnicodeObj(...,0); followed by a loop of calls: Tcl_AppendUnicodeToObj(objPtr, u, n); will now grow and append to the Unicode representation. Before this commit, the sequence would convert each append to UTF and perform the append to the UTF rep. This is puzzling and likely a bug. The performance of [string map] is significantly improved by this change (according to the MAP collection of benchmarks in tclbench). Just in case there was some wisdom in the old ways that I missed, I left in the ability to restore the old patterns with a #define COMPAT 1 at the top of the file.

| | | | | | | | 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.

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: 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.

This reduces memory requirement a small bit, and makes some range checks simpler to code.
* * 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.
