Partially fix the C++ + skeleton; a C++ expert needs to finish this. Remove debugging + msgids; there's little point to having them translated, since they + can be understood only by someone who can read the + (English-language) source code. + + Generate runtime-po/bison-runtime.pot automatically, so that we + don't have to worry about garbage getting in that file. We'll + make sure after the next official release that old msgids don't + get lost. See + . + + * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove. + Now auto-generated. + * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet. + Fix typos in explanations of the runtime file. + * bootstrap: Change gettext keyword from YYI18N to YY_. + Use standard Makefile.in.in in runtime-po, since we'll arrange + for backward-compatible bison-runtime.po files in a different way. + * data/glr.c (YY_): New macro, from yacc.c. + (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse): + Translate messages intended for users. + (yyreportSyntaxError): Change "virtual memory" to "memory" to match + the wording in the other skeletons. We don't know that the memory + is virtual. + * data/lalr1.cc (YY_): Renamed from _. All uses changed. + Use same method that yacc.c uses. + Don't translate debugging messages. + (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff; + it doesn't work (yet), and requires C++ expertise to fix. + * data/yacc.c (YY_): Renamed from YY18N. All uses changed. + Move defn to a more logical place, to be consistent with other + skeletons. + Don't translate debugging messages. + Don't assume line numbers fit in unsigned int; use unsigned long fmts. + * doc/bison.texinfo: Mention . Change glibc cross reference + to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS. + * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc. + + Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl. + * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return + void, not int. + * tests/glr-regression.at (Badly Collapsed GLR States): + Likewise. + (Improper handling of embedded actions and dollar(-N) in GLR parsers): + yylex should return 0 at EOF rather than aborting. + + Improve tests for stack overflow in GLR parser. + Problem reported by twlevo@xs4all.nl. + * data/glr.c (struct yyGLRStack): Remove yyerrflag member. + All uses removed. + (yyStackOverflow): Just longjmp, but with value 2 so that caller + can handle the problem. + (YYCHK1): Use goto (a la yacc.c) rather than setting a flag. + (yyparse): New local variable yyresult to record the result. + Use result of setjmp to set it, rather than storing itinto + struct. + (yyDone): Remove label. + (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels, + to mimic yacc.c. Do not discard lookahead if it's EOF (possible + if YYABORT is used). + * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with + yyparse status; put status > 1 into diagnostic. + Check that status==2 works. + * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at: + Use exit status 3 for failure to open (which shouldn't happen). + +2005-07-17 Paul Eggert + + * tests/conflicts.at (%nonassoc and eof): Don't exit with status + 1 on syntax error; just let yyparse do its thing. + * tests/glr-regression.at (Badly Collapsed GLR States): Likewise. + * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise. + (Exploding the Stack Size with Alloca): + (Exploding the Stack Size with Malloc): + Expect exit status 2, not 1, since the parser is supposed to blow + its stack. Problem reported by twlevo@xs4all.nl. + + * data/glr.c (yyparse): Don't assume that the initial calls + to YYMALLOC succeed; in that case, yyparse incorrectly returned 0. + Print a stack-overflow message and fail instead. + Initialize the line-number information before creating the stack, + so that the stack-overflow message can report line zero safely. + +2005-07-14 Paul Eggert + + Fix problems reported by twlevo@xs4all.nl. + * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined. + (yyuserMerge): Provide a default case if b4_mergers is empty. + * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE. + * tests/glr-regression.at + (Improper handling of embedded actions and dollar(-N) in GLR parsers): + Add casts to pacify C++ compilers. + * tests/glr-regression.at (Improper merging of GLR delayed action + sets): Declare yylex before using it. + * tests/Makefile.am (maintainer-check-g++): Fix a stray + $(GXX) that escaped the renaming of GXX to CXX. Remove bogus + test for valgrind; valgrind is independent of g++. + (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check + for compatibility with POSIX 1003.1-2001 (if running coreutils). + * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++. + Use a destructor, so that we can expand the stack. Change + YYSTYPE to char * so that we can free it. Cast result of malloc. + +2005-07-13 Paul Hilfinger + + * data/glr.c (yyuserAction): Fix uninitialized variable that caused + a valgrind failure. Problem reported by twlevo@xs4all.nl. + +2005-07-13 Paul Eggert + + * PACKAGING: New file, suggested by Bruno Haible and taken from + similar wording in gettext's PACKAGING file. + * NEWS: Mention PACKAGING. + * Makefile.am (EXTRA_DIST): Add PACKAGING. + +2005-07-12 Paul Eggert + + * NEWS: Document recent i18n improvements. + * bootstrap: Get runtime translations into runtime-po. + Create runtime-po files automatically, if possible. + * configure.ac: Invoke BISON_I18N, so that we eat our own dog food. + * data/yacc.c: Rewrite inclusion of so that ENABLE_NLS + does not infringe on the user's name space. + (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS. + * doc/bison.texinfo (Internationalization): Revamp the English + and Texinfo syntax a bit, to try to make it clearer. + (Bison Options, Option Cross Key): Mention --print-localedir. + * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to + YYENABLE_NLS.

These files are automatically generated. + * examples/extexi: Clarify that this file is now part of Bison, + not GNU M4, and that it works with any POSIX-compatible Awk. + * examples/calc++/Makefile.am (run_extexi): Remove; not used. + ($(calc_extracted)): Renamed from $(calc_sources_extracted), + so that we also get calc++-parser.yy. Geneate it. + Use $(AWK), not gawk, since any conforming Awk will do. + Put comment before action, since older 'make' can't handle comment + in action. + $(BUILT_SOURCES): List all built sources, not just some of them. + $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources. + $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT. + $($(calc_sources_generated)): Remove unnecessary test for existence + of target.
