* portability: fix several issues with M4 subprocess.Joel E. Denny2010-02-222-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Set push_parser = true and pull_parser = false for %push-parser. * src/scan-gram.l: Don't accept %push_parser as an alternative to %push-parser since there's no backward-compatibility concern here. Scan %push-pull-parser. * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser instead of %push-parser. * tests/headers.at (export YYLTYPE): Make yylex static, and don't prototype it in the module that calls yyparse. * tests/input.at (Torturing the Scanner): Likewise. * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
* * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoingPaul Eggert2006-11-081-0/+2
| | | | | | | the earlier change today), m4/intl.m4, m4/intldir.m4. This gives us a slightly cleaner distribution, and also works. * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent gnulib changes.
* * bootstrap.conf (gnulib_modules): Add config-h.Paul Eggert2006-10-131-0/+1

* Use some of gnulib's new modules, taken from coreutils.Paul Eggert2006-09-151-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * bootstrap: Sync from coreutils, except add support for gnulib_files. * bootstrap.conf: New file. (gnulib_modules): Add configmake, inttypes, unistd. (XGETTEXT_OPTIONS): Add complain, complain_at, fatal, fatal_at, warn, warn_at, unexpected_end. * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here. (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this. (gl_EARLY): Add. (AM_STDBOOL_H): Remove; gl_INIT now dows this. (gl_INIT): Add (GNULIB_AUTOCONF_SNIPPET): Remove. (AM_GNU_GETTEXT): Add; require formatstring macros since that's the pickiest. * lib/.cvsignore: Add inttypes_.h. * lib/Makefile.am: Include gnulib.mk first so we can append to it. (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils. (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove no-longer-necessary initializations. (lib_SOURCES): Remove, replacing by libbison_a_SOURCES. * lib/subpipe.c: Include <unistd.h> unconditionally, now that we use the unistd module. * src/system.h: Likewise. * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4, ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4, gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4. * src/Makefile.am (DEFS): Remove, since configmake does this for us. (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us. * src/system.h: Include inttypes.h unconditionally, now that we use the inttypes module. Don't bother to include stdint.h, since inttypes.h now does that for us. (LOCALEDIR): Remove, now that we use the configmake module. * src/getargs.c: Include configmake.h. * src/main.c: Likewise. * src/output.c: Likewise. * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib, not from $abs_top_builddir, since config.h moved.
* Add argmatch.m4. Remove obstack.m4, strerror_r.m4.Paul Eggert2006-09-111-2/+1
| | | | This adjusts to recent gnulib changes.
* * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,Paul Eggert2006-08-021-0/+8
| | | | | | | | | po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4. * bootstrap (gnulib_tool): Stop using --assume-autoconf; the latest gnulib does this a different way. (get_translations): Sharuzzaman Ahmat Raslan reported that the ms translation was patched, so stop omitting it.
* Update to latest gnulib and gettext versions.Paul Eggert2006-07-252-34/+0
| | | | | | | | | | | | | | | | | | | | | | | | * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer. Add fopen-safer. (gnulib_files): Add m4/warning.m4. Don't worry about files overwritten by autopoint. Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4. Suppress "id", "ms", "tr" translations for now, since gettext 0.15 rejects them. Don't use autoreconf; instead, invoke autopoint etc. by hand, so that we can remove the intl files at a better time. (intl_files_to_remove): Remove aclocal.m4, since it gets rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4, m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4, m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4. Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4. Remove datarootdir hack; no longer needed. * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING. (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15. * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c, strdup.h. * m4/.cvsignore: Remove hard-locale.m4, strdup.m4. * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
* Adjust to Autoconf 2.60 and today's gnulib.Paul Eggert2006-07-091-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * bootstrap (gnulib_modules): Add stdint. Remove special case for m4/onceonly_2_57.m4, since gnulib-tool no longer copies it. (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4, since stdint needs the former and wcwidth (which is now required by mbswidth) needs the latter. Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to work around a compatibility glitch between gettext 0.14.6 and Autoconf 2.60. * configure.ac (AC_PREREQ): Require Autoconf 2.60. Do not check for uintptr_t, since new stdint module does the right thing. * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h. Add stdint.h, stdint_.h, wcwidth.h. * m4/.cvsignore: Remove alloca.m4, onceonly.m4.

(file_name_split): Use last_component, not base_name, to adjust to gnulib changes. * src/parse-gram.h: Include <strverscmp.h> in the usual order for ../lib/*.h files. (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8): Define unconditionally, since we now assume the stdint module. * src/scan-skel.l: Include <dirname.h>. (BASE_QPUTS): Use last_component, not base_name. * src/system.h: Include <unlocked-io.h> in the usual order for ../lib/*.h files. Include <stdint.h> unconditionally, since we now use the stdint module. (uintptr_t): Declare if UINTPTR_MAX is not defined, not HAVE_UINTPTR_T, since we now use the stdint module. (base_name): Remove decl, since files now include <dirname.h> to get the decl.
* Fix some nits reported by twlevo.Paul Eggert2006-03-081-0/+1
| | | | | | | | | * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure" and "POSIX". Use more-modern syntax for URLs. Mention C++ and ask for Java. Don't hardwire OS version numbers. Add copyright notice. * m4/.cvsignore: Add unistd_h.m4, for latest gnulib. * src/conflicts.c (solved_conflicts_obstack): Now static.
