a9739e7c4c * tests/glr-regression.at (Duplicated user destructor for lookahead):
Mark it as expected to fail.
Cast result of malloc; problem reported by twlevo@xs4all.nl.
* tests/actions.at, tests/calc.at, tests/glr-regression.at:
Don't start user-code symbols with "yy", to avoid name space problems.

f479c6c61e Remove the traits, failed experiment.
It never proved useful, and anyway because of the current
definition, it was not possible to have several specialization of
this traits, making it useless.
* data/lalr1.cc (yy:traits): Remove.
Inline its definitions in the parser class.

e2586f82b0 * tests/atlocal.in (LIBS): Pass INTLLIBS to address failures on at
least Mac OSX with a /usr/local install of gettext.

1bd0dedaaa * NEWS: Version 2.1.
* NEWS: Remove notice of yytname change, since it was never in an
official release.
* data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
diagnostic.
* src/output.c (prepare): Likewise.
* data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
(yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
is not defined.  This is an awful hack, but it's enough for now.
All callers changed.
* tests/glr-regression-at (make_value): Args are const pointers now,
to avoid GCC warning.
(Duplicated user destructor for lookahead): New test.  Currently
skipped.  It fails on my host but I'm not sure it'll always fail.

dbcdae2d04 * data/lalr1.cc (yylex_): Remove, inline its code.
(yyreport_syntax_error_): Remove, replaced by...
(yysyntax_error_): this which returns a string and leaves to the
caller the call to the users' error function.
(yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
Move from members of the parser object...
(yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):
to local variables of the parse function.

dd5f2af2bd * 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

ca5d201376 * Makefile.am (SUBDIRS): Put examples before tests, so that
"make check" doesn't finish with "All 1 tests passed".
2005-07-25 06:45:32 +00:00
Paul Eggert
3d54b57635 * 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.

d53ae497dc * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent

040984073a * NEWS: Version 2.0b.
* 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".

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.

* tests/sets.at: Likewise.

* data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
we comment out the Autoconf version number.
* doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
it's error-prone and "make maintainer-distcheck" rejects it.

* lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
Indent calls to "error" to pacify "make maintainer-distcheck",
when the calls are not intended to be translated.
* m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.

* 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".

258b75caaa 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.

1a05945136 * 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".
2005-07-19 00:05:57 +00:00

97460c7864 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf. 2005-07-18 22:16:44 +00:00
Paul Eggert
30757c8c93 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.

ac8c5689f8 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.

6100a9aa2e 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).
2005-07-18 18:09:40 +00:00
Paul Eggert
67fd79c427 * 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.
2005-07-18 06:14:16 +00:00
Paul Eggert
15f40952f7 * 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.

(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):
YYSTYPE is char *, not char const *, so that strcpy ($$, ...) works.

Paul Eggert
1beb0b24f3 * tests/glr-regression.at (Improper merging of GLR delayed action

Paul Eggert
a22ff96f32 * tests/Makefile.am (maintainer-check-g++): 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.
