* Demonstrate and fix memory leak in Tcl_ParseVar().dgp2013-07-241-0/+1

* Tests for expanded literals quoting detection.dgp2011-05-021-3/+5
|
* Revised TclFindElement() interface.dgp2011-05-021-21/+13
| | | | | | | | | | | | | | | | The final argument had been bracePtr, the address of a boolean var, where the caller can be told whether or not the parsed list element was enclosed in braces. In practice, no callers really care about that. What the callers really want to know is whether the list element value exists as a literal substring of the string being parsed, or whether a call to TclCopyAndCollpase() is needed to produce the list element value. Now the final argument is changed to do what callers actually need. This is a better fit for the calls in tclParse.c, where now a good deal of post-processing checking for "naked backslashes" is no longer necessary. ***POTENTIAL INCOMPATIBILITY*** For any callers calling in via the internal stubs table who really do use the final argument explicitly to check for the enclosing brace scenario. Simply looking for the braces where they must be is the revision available to those callers, and it will backport cleanly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that builds a parse tree instead of operating with deep recursion. This corrects reports of stack-blowing crashes parsing long expressions [Bug 906201] and replaces a fundamentally O(N^2) algorithm with an O(N) one [RFE 903765]. The new parser is better able to generate error messages that clearly report both the nature and context of the syntax error [Bugs 1029267, 1381715]. For now, the code for the old parser is still present and can be activated with a "#define OLD_EXPR_PARSER 1". This is for the sake of a clean implementation patch, and for ease of benchmarking. The new parser is non-recursive, so much lighter in stack consumption, but it does use more heap, so there may be cases where parsing of long expressions that succeeded with the old parser will lead to out of memory panics with the new one. There are still more improvements possible on that point, though significant progress may require changes to the Tcl_Token specifications documented for the public Tcl_Parse*() routines. ***POTENTIAL INCOMPATIBILITY*** for any callers that rely on the exact (usually terrible) error messages generated by the old parser. This includes a large number of tests in the test suite. * generic/tclInt.h: Replaced TclParseWhiteSpace() with * generic/tclParse.c: TclParseAllWhiteSpace() which is what * generic/tclParseExpr.c: all the callers really needed. Breaking whitespace runs at newlines is useful only to the command parsing function, and it can call the file scoped routine ParseWhiteSpace() to do that. * tests/expr-old.test: Removed knownBug constraints that masked * tests/expr.test: failures due to revised error messages. * tests/parseExpr.test:
