* * generic/tclCompile.c: Re-implement Tcl_SubstObj() as a simpledgp2009-09-171-81/+20
| | | | | | | | | | * generic/tclParse.c: wrapper around TclNRSubstObj(). This has * tests/basic.test: the effect of caching compiled bytecode in * tests/parse.test: the value to be substituted. Note that Tcl_SubstObj() now exists only for extensions. Tcl itself no longer makes any use of it. Note also that TclSubstTokens() is now reachable only by Tcl_EvalEx() and Tcl_ParseVar() so tests aiming to test its functioning needed adjustment to still have the intended effect.

These sections were mostly in place to enable [info frame] to discover line information in expanded literals. Since the parser now generates a token for each post-expansion word referring to the right location in the original script string, [info frame] gets all the data it needs. * generic/tclInt.h: Revised the parser so that it never produces * generic/tclParse.c: TCL_TOKEN_EXPAND_WORD tokens when parsing an * tests/parse.test: expanded literal word; that is, something like {*}{x y z}. Instead, generate the series of TCL_TOKEN_SIMPLE_WORD tokens to represent the words that expansion of the literal string produces. [RFE 1725186]

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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:
