+
+	portability: fix several issues with M4 subprocess.
+
+	M4's output pipe was not being drained upon fatal errors during
+	scan_skel.  As a result, broken-pipe messages from M4 were seen
+	on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
+	failure in the test suite.  The problem was that, on platforms
+	where the default disposition for SIGPIPE is ignore instead of
+	terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
+	then reported it.  However, there's some sort of race condition,
+	because the new test group occasionally succeeded.
+	Reported by Albert Chin at
+	<http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.
+
+	There were also problems with the test suite livelocking on
+	Tru64 5.1b.  Reported by Didier Godefroy at
+	<http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>.
+	Switching to create_pipe_bidi suggested by Akim Demaille.
+
+	To attempt to solve both of these problems, switch to gnulib's
+	create_pipe_bidi and register M4 process as a slave.  Along the
+	way, clean up file name conflict handling, which was affected by
+	the broken-pipe problem before the switch.
+	* NEWS (2.4.2): Document.
+	* THANKS (Didier Godefroy): Add.
+	* bootstrap.conf (gnulib_modules): Add pipe.
+	* gnulib: Update to latest to make sure we have all the latest
+	fixes.
+	* lib/Makefile.am (libbison_a_SOURCES): Remove subpipe.h and
+	subpipe.c.
+	* po/POTFILES.in (lib/subpipe.c): Remove.
+	* src/files.c (compute_output_file_names): Update invocations
+	of output_file_name_check.
+	(output_file_name_check): In the case that the grammar file
+	would be overwritten, use complain instead of fatal, but replace
+	the output file name with /dev/null.  Use the /dev/null solution
+	for the case of two conflicting output files as well because it
+	seems safer in case Bison one day tries to open both files at
+	the same time.
+	* src/files.h (output_file_name_check): Update prototype.
+	* src/output.c (output_skeleton): Use create_pipe_bidi and
+	wait_subprocess.  Assert that scan_skel completely drains the
+	pipe.
+	* src/scan-skel.l (at_directive_perform): Update
+	output_file_name_check invocation.
+	* tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Check that the

Author	SHA1	Message	Date
Joel E. Denny	06d61f775a	Version 2.4.3. * NEWS (2.4.3): Set date.	2010-08-05 20:56:44 -04:00
Joel E. Denny	b3b1806888	maint: add gettext version to release announcements. Suggested by Paul Hilfinger at <http://lists.gnu.org/archive/html/bison-patches/2010-07/msg00019.html> <http://lists.gnu.org/archive/html/bison-patches/2010-08/msg00002.html>. * cfg.mk (bootstrap-tools): Add gettext.	2010-08-04 21:15:59 -04:00
Joel E. Denny	3ffdd5f125	doc: fix -W and %expect documentation some. * NEWS (2.4.3): Mention that there are documentation fixes. * doc/bison.texinfo (Expect Decl): Make it clear that %expect turns conflicts into errors not warnings. (Shift/Reduce): Likewise. (Bison Options): Don't mention -Wsyntax. It doesn't exist.	2010-08-04 20:17:40 -04:00
Joel E. Denny	954474bfa1	-Werror: fix for rules useless in parser after conflicts. * NEWS (2.4.3): Document fix. * src/complain.c (error_message): Extend to handle incomplete error messages so warn and warn_at can be used in more cases. * src/gram.c (grammar_rules_useless_report): Use warn_at so that -Werror is always obeyed. * src/reduce.c (reduce_print): Use warn so that the "warnings being treated as errors" message is printed consistently before the first warning message. This makes testing easier. * tests/local.at (AT_BISON_WERROR_MSG): New macro. (AT_BISON_CHECK_NO_XML): Extend to check -Werror and --warnings=error when warnings appear in bison's stderr.	2010-08-01 22:31:10 -04:00
Joel E. Denny	122ff44429	maint: enable gnits only at stable releases. * configure.ac (AM_INIT_AUTOMAKE): Underscore or dash in a version string should disable gnits. Explain in comments.	2010-07-29 23:11:12 -04:00
Joel E. Denny	6895eefc04	Prepare for 2.4.3 release. * NEWS (2.4.3_rc1): Rename back to... (2.4.3): ... this, and unset date.	2010-07-29 21:55:02 -04:00
Joel E. Denny	d45746a0b7	Version 2.4.3_rc1. * NEWS (2.4.3): Rename to... (2.4.3_rc1): ... this for now so we can include translation updates in 2.4.3, and set release date. * configure.ac (AM_INIT_AUTOMAKE): Underscore rather than dash in version string now indicates a release candidate and that we thus cannot enable gnits. Dash confuses git-version-gen.	2010-07-29 20:50:21 -04:00
Joel E. Denny	4b07bd01d8	i18n: fix for gnulib. * po/POTFILES.in: Add remaining gnulib files that have translatable strings.	2010-07-28 21:46:07 -04:00
Joel E. Denny	e565556458	maint: use announce-gen's new --mail-headers. * HACKING (Announce): Update instructions. * cfg.mk (announcement_Cc_): Define. * configure.ac (AM_GNU_GETTEXT_VERSION): Update to 0.18 as required by latest gnulib. * gnulib: Update to latest.	2010-07-25 19:41:48 -04:00
Akim DemailleandJoel E. Denny	189ba6670f	build: require gettext 0.17. Suggested by Bruno Haible. http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00009.html * configure.ac: require gettext 0.17 to ensure compatibility with gnulib. (cherry picked from commit `af6d235843`)	2010-07-25 19:17:56 -04:00
Joel E. Denny	c027cccb35	tests: handle Valgrind that complains about >&-. * tests/output.at (AT_CHECK_OUTPUT): Extend to accept pre-tests. (Output files: -dv >&-): Skip test group if running maintainer-check-valgrind.	2010-07-24 16:43:22 -04:00
Akim Demaille	a151f354cf	Pacify gcc warnings. * src/getargs.c (skeleton_arg): Pass "%s" to printf-like functions with variable format and no argument.	2010-07-21 18:12:42 +02:00

This fix is already implemented in glr.c and does not apply to lalr1.java. * data/lalr1.cc (yy::parser::parse): Increase size of yyerror_range and adjust subscripting so you don't have to subtract one from the beginning of the array. * data/yacc.c (b4_declare_parser_state_variables, yyparse, yypush_parse): Likewise.	2010-04-03 14:58:22 -04:00
Joel E. Denny	18493762be	portability: fix test suite for GCC 4.5's new #error message. Reported by Tys Lefering at <http://lists.gnu.org/archive/html/bug-bison/2010-03/msg00030.html>. * NEWS (2.4.3): Mention. * tests/synclines.at (AT_TEST_SYNCLINE): Implement.	2010-04-03 13:28:51 -04:00

Joel E. Denny	cf80e9c386	portability: fix for BSD make. Reported by Johan van Selst at <http://lists.gnu.org/archive/html/bug-bison/2010-03/msg00016.html>. * tests/Makefile.am ($(TESTSUITE)): Qualify package.m4 in this dependency list as in package.m4's target rule.	2010-03-23 20:21:59 -04:00
Joel E. Denny	311b2e56ea	portability: fix spawning on at least FreeBSD 8 and FreeBSD 9. Reported by Johan van Selst at <http://lists.gnu.org/archive/html/bug-bison/2010-03/msg00014.html>. * NEWS (2.4.3): New. * THANKS (Johan van Selst): Add. * gnulib: Update to latest.	2010-03-23 12:37:50 -04:00
Joel E. Denny	895c37a5c7	maint: update for changes to gnulib's announce-gen. * HACKING (Announce): RELEASE_TYPE=major must now be written RELEASE_TYPE=stable. (cherry picked from commit `5a3c69f103`)	2010-03-23 12:37:50 -04:00
Joel E. Denny	08090fe64c	Version 2.4.2. * NEWS (2.4.2): Set version and date. For the recent test suite portability fixes, don't be so optimistic about their success given the lack of feedback on the affected platforms.	2010-03-20 13:10:09 -04:00
Joel E. Denny	c76f5dfb03	Prepare for 2.4.2 release. * NEWS (2.4.1b): Rename back to... (2.4.2): ... this, and unset date. * configure.ac (AM_INIT_AUTOMAKE): Re-enable gnits.	2010-02-22 23:58:13 -05:00
Joel E. Denny	2ad7e09e96	Version 2.4.1b. * NEWS (2.4.2): Rename to... (2.4.1b): ... this for now. Set date. * configure.ac (AM_INIT_AUTOMAKE): Disable gnits for now because it does not like this version name.	2010-02-22 21:59:18 -05:00
Joel E. Denny	a3d760ef5d	tests: fix maintainer-xml-check for recent changes. * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Use AT_BISON_CHECK_NO_XML rather than AT_BISON_CHECK because an output file whose name conflicts with a previous output file is now never generated.	2010-02-22 21:54:34 -05:00
Joel E. Denny	22cc8d813e	portability: fix several issues with M4 subprocess. M4's output pipe was not being drained upon fatal errors during scan_skel. As a result, broken-pipe messages from M4 were seen on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a failure in the test suite. The problem was that, on platforms where the default disposition for SIGPIPE is ignore instead of terminate, M4 sometimes saw fwrite fail with errno=EPIPE and then reported it. However, there's some sort of race condition, because the new test group occasionally succeeded. Reported by Albert Chin at <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>. There were also problems with the test suite livelocking on Tru64 5.1b. Reported by Didier Godefroy at <http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>. Switching to create_pipe_bidi suggested by Akim Demaille. To attempt to solve both of these problems, switch to gnulib's create_pipe_bidi and register M4 process as a slave. Along the way, clean up file name conflict handling, which was affected by the broken-pipe problem before the switch. * NEWS (2.4.2): Document. * THANKS (Didier Godefroy): Add. * bootstrap.conf (gnulib_modules): Add pipe. * gnulib: Update to latest to make sure we have all the latest fixes. * lib/Makefile.am (libbison_a_SOURCES): Remove subpipe.h and subpipe.c. * po/POTFILES.in (lib/subpipe.c): Remove. * src/files.c (compute_output_file_names): Update invocations of output_file_name_check. (output_file_name_check): In the case that the grammar file would be overwritten, use complain instead of fatal, but replace the output file name with /dev/null. Use the /dev/null solution for the case of two conflicting output files as well because it seems safer in case Bison one day tries to open both files at the same time. * src/files.h (output_file_name_check): Update prototype. * src/output.c (output_skeleton): Use create_pipe_bidi and wait_subprocess. Assert that scan_skel completely drains the pipe. * src/scan-skel.l (at_directive_perform): Update output_file_name_check invocation. * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): Check that the grammar file actually isn't overwritten. (Conflicting output files: -o foo.y): Update expected output. * tests/skeletons.at (Fatal errors but M4 continues producing output): New test group.	2010-02-22 18:09:19 -05:00
Joel E. Denny	9398411bfc	Update POTFILES. * HACKING (Release Procedure): Add reminder about keeping POTFILES files up-to-date. * po/POTFILES.in (src/muscle_tab.c, src/scan-skel.l): Add.	2010-02-04 21:07:07 -05:00
Joel E. Denny	d093cf8cbd	tests: link lib/libbison.a for gnulib. This solves a problem on Solaris 2.7 where the testsuite needs at least gnulib's rpl_fopen. Reported by Albert Chin at <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00001.html>. * NEWS (2.4.2): Document. * tests/atlocal.in (LIBS): As for LDADD in src/Makefile.am, add lib/libbison.a.	2010-02-01 15:54:41 -05:00
Joel E. Denny	c412a490ec	Prepare for 2.4.2 release. * NEWS (2.4.1a): Rename back to... (2.4.2): ... this, and unset date. * configure.ac (AM_INIT_AUTOMAKE): Re-enable gnits.	2010-01-22 13:50:04 -05:00
