* data/lalr1.cc (parse): Catch syntax_error around yylex and
forward them to errlab1.
* tests/c++.at (Syntax error as exception): Check support for
syntax exceptions raised by the scanner.
* NEWS, doc/bison.texinfo: Document it.
* tests/local.mk (TESTSUITE_AT): Include plackage.m4.
Adjust dependencies.
Make testsuite.at its first argument.
(package.m4): Be silent.
(testsuite): Be silent.
Use $<.
* data/c.m4 (b4_parse_param_use): Also accept optional arguments
to "use".
Simplify callers.
* data/glr.c (yyuserAction): Simplify use of b4_parse_param_use.
(yy_reduce_print): Don't use b4_parse_param_use, as all the arguments
_are_ used.
* data/lalr1.cc (YY_SYMBOL_PRINT): Even when disabled, "use" the
symbol argument.
This neutralizes a warning in yypush_ when there are no symbols
with a semantic values.
(yy_destroy_): Remove useless "use" of yymsg.
See <http://lists.gnu.org/archive/html/bug-bison/2012-01/msg00120.html>.
Use quotearg as often as possible instead of leaving the choice of
the quotes to the translators. Use shorter messages. Factor similar
messages to a single format, to make localization easier.
* src/files.c, src/getargs.c, src/muscle-tab.c, src/reader.c
* src/scan-code.l, src/scan-gram.l, src/symtab.c:
Use quote() or quotearg_colon() on printf arguments instead of
quotes in the format string.
* data/bison.m4: Keep sync with the changes in muscle-tab.c.
* tests/skeletons.at, tests/input.at, tests/regression.at: Adjust
expected messages.
Standard output was never explicitly closed, so we could not
detect failure. Thus, bison would ignore the errors of writing
to a full file system and getting an I/O error on write, but only
for standard output, e.g., for --print-localedir, --print-datadir,
--help and some verbose output.
Now, "bison --print-datadir > /dev/full" reports the write failure:
bison: write error: No space left on device
Before, it would exit 0 with no diagnostic, implying success.
This is not an issue for "--output=-" or the other FILE-accepting
command-line options, because unlike most other GNU programs,
an output file argument of "-" is treated as the literal "./-",
rather than standard output.
* bootstrap.conf (gnulib_modules): Add closeout.
* src/main.c: Include "closeout.h".
Use atexit to ensure we close stdout.
* .gitignore: Ignore new files pulled in via gnulib-tool.
* lib/yyerror.c (yyerror): Use fputs and fputc rather than fprintf
with a mere "%s\n" format. Always return 0 now, on the assumption
that the return value was never used anyway.
Don't include <config.h> after all. This avoids a problem
reported by Thiru Ramakrishnan in
http://lists.gnu.org/archive/html/help-bison/2011-11/msg00000.html
* cfg.mk: Exempt lib/yyerror.c from the sc_require_config_h_first test.
* THANKS: Update.
This script hard-coded "libbison" and lib/gnulib.mk.
Adjust the script to require a --lib-name=$gnulib_name option
and a FILE argument like lib/$gnulib_mk.
Also add support for --help and --version.
* etc/prefix-gnulib-mk: Generalize.
* bootstrap.conf (bootstrap_post_import_hook): Update its invocation.
Updating to gnulib pulled in new quote and quotarg modules,
by which quoting is now done like 'this' rather than `this'.
That change induces many "make check" test failures. This change
adapts code and tests so that "make check" passes once again.
* src/scan-code.l: Quote like 'this', not like `this'.
* src/scan-gram.l: Likewise.
* src/symtab.c: Likewise.
* tests/actions.at: Adjust tests to match.
* tests/input.at: Likewise.
* tests/named-refs.at: Likewise.
* tests/output.at: Likewise.
* tests/regression.at: Likewise.
* lib/.gitignore: Regenerate.
* m4/.gitignore: Likewise.
Updating to the latest bootstrap from gnulib involves more of a
change than usual, and updating to the latest gnulib would involve
its own set of challenges with the upcoming quoting changes, so
we update bootstrap manually and separately.
* bootstrap: Update from gnulib.
* Makefile.am: Initialize more variables to empty, so that gnulib.mk
can append to them with "+=".
* bootstrap.conf (gnulib_mk_hook): Remove. No longer honored.
(bootstrap_post_import_hook): Instead, run the same command,
etc/prefix-gnulib-mk lib/$gnulib_mk, via slightly different API.
Temporarily disable "bootstrap_sync=true".
* etc/prefix-gnulib-mk: Don't prepend "lib/" to tokens like -I$(...
or "\".
* cfg.mk (exclude_file_name_regexp--sc_space_tab): Exempt
tests/input.at and tests/c++.at, since they appear to use
SP-TAB sequences deliberately.
* OChangeLog: Remove space-before-TAB.
* bootstrap.conf (gnulib_modules): Add gpl-3.0.
* doc/gpl-3.0.texi: Remove from version control, now that
we get it via gnulib.
* doc/.gitignore: Ignore it.
* lib/lbitset.c (lbitset_elt_find): Remove unnecessary test of "elt",
at a point where we know it is non-NULL, due to prior dereference.
Copyright (C) 1987-1988, 1991-2012 Free Software Foundation,
* lib/bitset_stats.c (bitset_stats_list): Remove declaration
and set of unused local, "type".
* lib/ebitset.c (ebitset_init): Likewise, for "size".
* lib/lbitset.c (lbitset_not): Likewise, for "elt".
This should help to avoid some portability problems. For example,
it would have revealed the empty unions fixed by the last patch
* configure.ac (WARN_CFLAGS_TESTS, WARN_CXXFLAGS_TEST): Implement.
* tests/synclines.at (AT_TEST_SYNCLINE): Avoid -pedantic warning
about an empty translation unit.
(cherry picked from commit 5422d56a71)
Empty unions are not accepted by the ISO C99 grammar or by at
least some versions of Sun Studio. Reported by Wolfgang S. Kechel
at
<http://lists.gnu.org/archive/html/bug-bison/2011-08/msg00003.html>.
* NEWS (2.5.1): Document fix.
* THANKS (Wolfgang S. Kechel): Add.
* tests/existing.at (GNU Cim Grammar)
(GNU pic (Groff 1.18.1) Grammar.): Remove empty %union.
(cherry picked from commit 7451638148)
This change was made by applying emacs' untabify function to
nearly all files in Bison's repository. Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.
The typo shows up in the `configure --help' output. Reported by
W.C.A. Wijngaards and Paul Eggert at
<http://lists.gnu.org/archive/html/bug-bison/2011-07/msg00000.html>.
* README-hacking (Release Procedure): Remind about updating
maintainer tools before a release.
* THANKS (W.C.A. Wijngaards): Add.
* configure.ac (AC_PREREQ): Set to 2.68, which fixes the YACC
typo.
