+ * bootstrap (no_cache): New var, to accommodate different wget
+ variants. Use it instead of '-C off'. Problem reported by
+ twlevo@xs4all.nl.
+
+ * data/glr.c (yydestroyStackItem): New function.

+
+2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
+
+ * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
+ Add strnlen.c.
+ * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
+ lib-prefix.m4, po.m4.
+
+ * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
+ in yydestruct diagnostic, since it might not be an error.
+ Problem reported by Joel Denny near end of
+ <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
+ * data/lalr1.cc (yyerturn): Likewise.
+ * data/yacc.c (yyreturn): Likewise.
+ * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
+
+ * src/files.c: Remove obsolete FIXME comment.
+
+ * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
+ with the other templates, and to fix bogus run-on messages such
+ as the one reported at the end of
+ <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
+ All callers changed to avoid the newline.
+ (yyprocessOneStack): Output two lines rather than one, to accommodate
+ the above change. This changes the debug output format slightly.
+
+ * data/glr.c (yyresolveValue): Fix redundant parse tree problem
+ reported by Joel E. Denny in
+ <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
+ (trivial change).
+ * tests/glr-regression.at (Duplicate representation of merged trees):
+ New test, from Joel E. Denny in:
+ <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
+ * THANKS: Add Joel E. Denny.
+
+ * configure.ac (AC_INIT): Bump to 2.0c.
+
+2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Version 2.0b.
+
+ * Makefile.am (SUBDIRS): Put examples before tests, so that
+ "make check" doesn't finish with "All 1 tests passed".
+
+ * tests/regression.at (Token definitions): Don't rely on
+ AT_PARSER_CHECK for data that contains backslashes. It currently
+ uses 'echo', and 'echo' isn't portable if its argument contains
+ backslashes. Problem found on OpenBSD 3.4. Also, do not assume
+ that the byte '\0xff' is not printable in the C locale; it is,
+ under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
+ not printable, so use '\0x81' to test.
+
+ * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
+ version of GCC, since the macro is used with non-GCC compilers.
+
+ Fix core dump reported by Pablo De Napoli in
+ <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
+ * tests/regression.at (Invalid inputs with {}): New test.
+ * src/parse-gram.y (token_name): Translate type before using
+ it as an index.
+
+ * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
+ the user's name space. All uses changed to __attribute__
+ ((__unused__)).
+ (yyFail, yyMemoryExhausted, yyreportAmbiguity):
+ Add __attribute__ ((__noreturn__)).
+
+ * etc/clcommit: Remove. We weren't using it, and it failed
+ "make maintainer-distcheck".
+ * Makefile.maint: Merge from coreutils.
+ (CVS_LIST, CVS_LIST_EXCEPT): New macros.
+ (syntax-check-rules): Change list of rules as described below.
+ (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):

+ Use CVS_LIST and CVS_LIST_EXCEPT.
+ (header_regexp, h_re): Remove.
+ (dd_c): New macro.
+ (sc_dd_max_sym_length, .re-list, news-date-check): New rules.

+ Restore old updating code, even though we don't use it, so
+ that we're the same as coreutils.
+ (alpha, beta, major): Depend on news-date-check.
+ Make the upload commands.

+ * src/main.c (main): Cast bindtextdomain and textdomain calls to
+ void, to avoid warning when NLS is disabled.
+ * src/output.c: Include scan-skel.h.
+ (scan_skel): Remove decl, since scan-skel.h does this.
+ (output_skeleton):
+ Indent calls to "error" to pacify "make maintainer-distcheck".
+ * src/print_graph.c: Don't include <obstack.h>, as system.h does this.

+
+ * tests/torture.at: Revamp to avoid misuse of atoi that

+
+ * examples/extexi (message): Don't print a message more than once,

+ that informative messages are worth worrying about.
+
+2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * configure.ac: Update version number.
+
+ * Makefile.am (SUBDIRS): Add examples; somehow this got removed
+ accidentally.
+ * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
+ autogenerated by the maintainer.
+ * examples/calc++/.cvsignore: Add *.yy.
+
+ * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
+ * lib/bitset_stats.c (bitset_stats_init): Likewise.
+ * lib/bitsetv.c (bitsetv_alloc): Likewise.
+
+ * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
+
+ * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
+ from maintainer-distcheck about casting the argument of 'free'.
+
+ * NEWS: Mention recent yytname changes.
+ * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
+
+ * bootstrap: For translations that have not yet been upgraded to
+ the new runtime-po domain, prime the pump by extracting the
+ relevant strings from the obsolete translations. This code can be
+ removed once the bison-runtime domain has been translated by each
+ team.
+
+ * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
+ now that token names are already quoted.
+
+ Fix problem reported by Anthony Heading.
+ * data/glr.c (YYTOKEN_TABLE): New macro.
+ (yytname): Define if YYTOKEN_TABLE.
+ * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
+ * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.

+
+2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
+ again if the first call fails.
+
+ * data/glr.c (yytnamerr): New function.
+ (yyreportSyntaxError): Use it to dequote most string literals.
+ * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
+ with other skeletons. All uses changed.
+ (yytnameerr_): New function.
+ (yyreport_syntax_error): Use it to dequote most string literals.
+ * data/yacc.c (yytnamerr): New function.
+ (yyerrlab): Use it to decode most string literals.
+ * doc/bison.texinfo (Decl Summary, Calling Convention):
+ Clarify quoting convention of yytname.
+ * src/output.c (prepare_symbols): Quote all names. This undoes
+ the 2005-04-17 change, which is now accomplished (mostly) via
+ changes in the parsers as described above.
+ * tests/regression.at (Token definitions, Web2c Actions):
+ Undo most 2005-04-17 change here, too.
+
+2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix more problems reported by twlevo@xs4all.nl.
+ * tests/cxx-type.at: Don't pipe output of ./types through sed to
+ remove trailing spaces. This loses the exit status of ./types,
+ and isn't needed since ./types shouldn't be emitting trailing
+ spaces.
+ * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
+ as the stack isn't valid in that case.
+
+ * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
+ (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
+ (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
+ Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
+ is used.
+ * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
+ (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
+ (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
+ Likewise.
+
+ * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
+ overly-picky compilers that reject 'char *foo = "bar";'.
+
+ * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
+ to FILE * parameter, not to stderr. This fixes a typo introduced
+ in the 2005-07-12 change.
+
+ * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
+ warnings from GCC 4.
+
+ * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
+ (yyglrShiftDefer, yysplitStack):
+ Remove unused parameters b4_pure_formals. All uses changed.
+ (yyglrShift): Remove unused parameters b4_user_formals.
+ All uses changed.
+ (yyglrReduce): Removed unused parameter yylocp. All uses changed.
+
+2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
+
+ Destructor cleanups and regularization among the three skeletons.
+ * NEWS: Document the behavior changes.
+ * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
+ stack before failing, as the cleanup code will do it for us now.
+ * data/lalr1.cc (yyerrlab): Likewise.
+ * data/glr.c (yyparse): Pop everything off the stack before
+ freeing it, so that destructors get called properly.
+ * data/lalr1.cc (yyreturn): Likewise.
+ * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
+ This is more consistent.
+ * doc/bison.texinfo (Destructor Decl): Mention more reasons
+ why destructors might be called. 1.875 -> 2.1.
+ (Destructor Decl, Decl Summary, Table of Symbols):
+ Some English-language cleanups for %destructor.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
+ Add output line for destructor of start symbol.
+ * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
+ because of that same extra output line.
+
+ * NEWS: Document minor wording changes in diagnostics of
+ Bison-generated parsers.
+ * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
+ Remove unused formals. All uses changed.
+ (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
+ (yyparse): Rename yyoverflowlab to yyexhaustedlab.
+ * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
+ Rename yyoverflowab to yyexhaustedlab.
+ When memory exhaustion occurs during syntax-error reporting,
+ report it separately rather than in a single diagnostic; this
+ eases translation.
+ * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
+ (Memory Exhausted): Renamed from Parser Stack Overflow.
+ Revamp wording slightly to prefer "memory exhaustion".
+ * tests/actions.at: "parser stack overflow" -> "memory exhausted".
+
+ * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
+
+ Add i18n support to the GLR skeleton. 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
+ <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
+
+ * 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 <libintl.h>. 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 <eggert@cs.ucla.edu>
+
+ * 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.
