+
+ * NEWS: Bison-generated C parsers no longer quote literal strings
+ associated with tokens.
+ * src/output.c (prepare_symbols): Don't escape strings,
+ since users don't want to see C escapes.
+ * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
+ in diagnostics.
+ * tests/input.at (Torturing the Scanner): Likewise.
+ * tests/regression.at (Token definitions, Web2c Actions): Likewise.
+
+2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
+ the data size is known to be too small and we can't increase it.
+ This works around an HP-UX 11.00 glitch reported by Andrew Benham.
+
+2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/parse-gram.y: Include quotearg.h.
+ (string_as_id): Quote $1 before using it as a key, since the
+ lexer no longer quotes it for us.
+ (string_content): Don't strip quotes, since lexer no longer
+ quotes it for us.
+ * src/scan-gram.l: Include quotearg.h.
+ ("\""): Omit quote.
+ ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
+ a key, since the rest of the lexer doesn't quote it.
+ * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
+ * tests/regression.at (Token definitions): Check for backslashes
+ in token strings.
+
+ * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
+ (YYSIZE_T): Define to unsigned long int when using an older compiler.
+ (yyparse): Revamp code to generate long syntax error message, to
+ make it easier to translate, and to avoid problems with arithmetic
+ overflow. Change "virtual memory" to "memory" in diagnostic, since
+ we don't know whether the memory is virtual.
+
+2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Bison-generated C parsers now use the _ macro to
+ translate strings.
+ * data/yacc.c (_) [!defined _]: New macro.
+ All English strings wrapped inside this macro.
+ * doc/bison.texinfo (Bison Parser): Document _.
+ * po/POTFILES.in: Include src/parse-gram.c, since it now
+ includes translateable strings that parse-gram.y doesn't.
+
+2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/symtab.c (symbol_make_alias): Call symbol_type_set,
+ reverting the 2004-10-11 change to this function.
+ (symbol_check_alias_consistency): Don't call symbol_type_set
+ if the type name is already correct.
+ * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
+
+2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/regression.at (Token definitions): Don't use a token named
+ c, as that generates a "#define c ..." that runs afoul of buggy
+ stdlib.h that uses the identifier c as a member of struct
+ drand48_data. Problem reported by Horst Wente.
+
+2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap: Change translation URL from
+ http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
+ http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
+ redirection glitches. Problem reported by twlevo@xs4all.nl.
+
+2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
+ after operands; POSIX says this isn't portable for the c99 command.
+
+2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/glr-regression.at (glr-regr2a.y): Try to dump core
+ immediately if a data overrun has occurred; this may help us track
+ down what may be a spurious failure on MacOS.
+
+2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
+
+ Respond to problems reported by twlevo@xs4all.nl.
+
+ * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
+
+ * src/vcg.h: Comment fix.
+ * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
+ (G_CMAX): Change to -1 instead of INT_MAX.
+
+ * data/yacc.c (yyparse): Omit spaces before #line.
+
+2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/tables.c (state_number_to_vector_number): Put it inside an
+ "#if 0", since it's not currently used. Problem reported by
+ Roland McGrath.
+
+2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/output.c (escaped_output): Renamed from
+ escaped_file_name_output, since we now use it for symbol tags as
+ well. All uses changed.
+ (symbol_destructors_output, symbol_printers_output):
+ Escape symbol tags too.
+ Problem reported by Matyas Forstner in
+ <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
+
+ * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
+ not needed.
+ * src/output.c (user_actions_output, token_definitions_output,
+ symbol_destructors_output, symbol_printers_output): Likewise.
+ * src/reader.c (prologue_augment): Likewise.
+ * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.

+ * src/vcg.c (output_edge): Don't quote linestyle arg.
+ Problem reported by twlevo@xs4all.nl.
+
+2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
+ example, reported by Derek M Jones. Also, make the example even
+ more outrageous, to better illustrate how bad the problem is.
+
+2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
+ putsym. Typo reported by Sebastian Piping.
+
+2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Language and Grammar): some -> same
+ (Epilogue): int he -> in the
+ Typos reported by Sebastian Piping via Justin Pence.
+
+2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/glr-regression.at (Improper handling of embedded actions
+ and dollar(-N) in GLR parsers): Renamed from "Improper handling of
+ embedded actions and $-N in GLR parsers", work around an Autoconf bug
+ with dollar signs in test names.
+ * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
+ for a similar reason.
+
+2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
+ wants to redefine G_VIEW.
+
+2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/vcg.c (get_view_str): Remove case for normal_view.
+ Problem reported by twlevo@xs4all.nl.
+
+2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
+ Problem reported by twlevo@xs4all.nl.
+
+ * doc/bison.texinfo: Change @dircategory from "GNU programming
+ tools" to "Software development". Requested by Richard Stallman
+ via Karl Berry.
+
+2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
+ Problem reported by twlevo@xs4all.nl.
+
+2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
+ keyword; it's not needed with modern compilers, and it doesn't
+ affect correctness with older compilers. Suggested by
+ twlevo@xs4all.nl.
+
+2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (yyuserAction): Add "default: break;" case to pacify
+ gcc -Wswitch-default.
+ * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
+ * data/yacc.c (yyparse): Likewise.
+
+2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
+ already. Let config.h define any nonstandard values.
+
+2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
+ for the benefit of slower hosts. Problem reported by
+ Nelson H. F. Beebe.
+
+2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
+ being defined and not used.
+ * data/lalr1.cc (yyparse): Likewise.
+ Use "if (false)" rather than "if (0)".
+
+2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
+
+ * TODO: Mention that we should allow NUL bytes in tokens.
+
+2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/scan-skel.l (<<EOF>>): Don't close standard output.
+ Problem reported by Hans Aberg.
+
+2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/getargs.c (version): Happy new year; update overall
+ program copyright date from 2004 to 2005.
+
+ * src/scan-skel.l ("@output ".*\n): Don't close standard output.
+ Problem reported by Hans Aberg.
+ * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
+ (Output file names.): Add a test for the case when standard output
+ is closed.
+
+2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
+ to fix an oversight in the Bison 2.0 manual.
+
+2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Version 2.0. Reformat the existing news items since
+ 1.875, so that related items are grouped together.
+ * configure.ac (AC_INIT): Bump version to 2.0.
+ * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
+
+ * tests/torture.at (Exploding the Stack Size with Alloca): Set
+ YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
+ otherwise, we're not testing alloca. Unfortunately there's no
+ simple way to consult HAVE_ALLOCA here.
+
+ * data/lalr1.cc (yydestruct_): Pacify unused variable warning
+ for yymsg, too.
+
+ * src/LR0.c (new_itemsets): Use memset rather than zeroing by
+ hand. This avoids a warning about comparing int to size_t when
+ GCC warnings are enabled.
+
+2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Bison-generated parsers no longer default to using the
+ alloca function (when available) to extend the parser stack, due
+ to widespread problems in unchecked stack-overflow detection.
+ * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
+ responsibility to set it to a positive value. This lets the user
+ specify a value that is not a preprocessor constant.
+ * data/yacc.c (YYMAXDEPTH): Likewise.
+ (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
+ * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
+ to be a compile-time constant. However, explain the constraints on it.
+ Also, explain the constraints on YYINITDEPTH.
+ (Table of Symbols): Explain that alloca is no longer the default.
+ Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
+ to 1.
+
+ * doc/bison.texinfo (Location Default Action): Mention that n must
+ be zero when k is zero. Suggested by Frank Heckenbach.
+
+2004-12-22 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
+ (parser::state_type, parser::semantic_type, parser::location_type):
+ Private, not public.
+ (parser::parse): Return ints, not bool.
+ Returning a bool introduces a problem: 0 corresponds to false, and
+ it seems weird to return false on success. Returning true changes
+ the conventions for yyparse.
+ Alternatively we could return void and send an exception.
+ There is no clear consensus (yet?).
+ (state_stack, semantic_stack, location_stack): Rename as...
+ (state_stack_type, semantic_stack_type, location_stack_type): these.
+ Private, not public.
+ * tests/c++.at: New.
+ * tests/testsuite.at, tests/Makefile.am: Adjust.
+
+2004-12-21 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (parser::parse): Return a bool instead of an int.
+
+2004-12-21 Akim Demaille <akim@epita.fr>
+
+ Don't impose std::string for filenames.
+
+ * data/lalr1.cc (b4_filename_type): New.
+ (position::filename): Use it.
+ (parser.hh): Move the inclusion of stack.hh and location.hh below
+ the user code, so that needed headers for the filename type can be
+ included first.
+ Forward declare them before the user code.
+ * tests/Makefile.am (check-local, installcheck-local): Pass
+ TESTSUITEFLAGS to the TESTSUITE.
+
+2004-12-20 Akim Demaille <akim@epita.fr>
+
+ Use more STL like names: my_class instead of MyClass.
+
+ * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
+ (SemanticStack, SemanticType, StateStack, StateType)
+ (TokenNumberType, Stack, Slice, Traits, Parser::location)
+ (Parser::value): Rename as...
+ (location_stack, location_type, rhs_number_type, semantic_stack)
+ (semantic_type, state_stack, state_type, token_number_type, stack)
+ (slice, traits, parser::yylloc, parser::yylval): these.
+
+ * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
+
+2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
+ * data/yacc.c (YYLLOC_DEFAULT): Likewise.
