| * do not ignore errors like ENOSPC,EIO when writing to stdoutJim Meyering2012-01-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (cherry picked from commit acb5895680611f8beb497b41694d9686f2932c50) Conflicts: m4/.gitignore

| * build: manually update bootstrap from gnulib, and adaptJim Meyering2012-01-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. * lib/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. (gnulib_tool_option_extras): Generate gnulib.mk. (cherry picked from commit 85ad742d4e94345d5ac07755f6722344cfd49603) Conflicts: Makefile.am bootstrap.conf etc/prefix-gnulib-mk
| * maint: get gpl-3.0 from gnulibJim Meyering2012-01-221-1/+1
| | | | | | | | | | | | | | | | * 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. (cherry picked from commit b87414a05e43ed270d5a88d365d0139f43acb34d)

| * Pacify -DGNULIB_POSIXCHECK.Joel E. Denny2011-05-011-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * bootstrap.conf (gnulib_modules): Add all modules suggested by -DGNULIB_POSIXCHECK. * src/files.c (file_name_split) * src/getargs.c (getargs) * src/location.c (boundary_set_from_string) * src/output.c (token_definitions_output, output_skeleton) * src/parse-gram.y (prologue_declaration) * src/scan-gram.l (handle_syncline) * src/symtab.c (symbol_new): Use mbschr and mbsrchr instead of strchr and strrchr. In the cases of command-line options, file names, and thus locations, functionality may be improved. In the case of symbol names, there should be no functional difference as all characters are ASCII, so the intended benefit is just warning suppression.
| * gnulib, autoconf: update.Joel E. Denny2011-04-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * README-hacking (Updating a submodule): Give advice on how to determine the versions of gnulib and autoconf to which we should update. (Release Procedure): Note that submodules should be updated. * bootstrap.conf (gnulib_modules): Rename pipe to spawn-pipe as suggested in updated gnulib NEWS. * gnulib: Choose a stable snapshot according to advice in Bison's README-hacking. * po/POTFILES.in (lib/pipe.c): Rename to... (lib/spawn-pipe.c): ... this. * src/output.c: Update to include spawn-pipe.h. * submodules/autoconf: Update to latest for improvement in m4.m4 that excludes M4 with buggy strstr. The only other changes to files that we use are copyright updates.
| * maint: don't update copyright years in bootstrap.Joel E. Denny2011-01-031-0/+5
| | | | | | | | | | | | | | | | | | | | * .x-update-copyright: Add entry for bootstrap. * bootstrap: Remove 2011 from copyright years. The bootstrap version we're currently using comes from an older version of gnulib. * bootstrap.conf (bootstrap_sync): Add comments explaining this issue. (cherry picked from commit 355bdbdc723fe79beb6a8aeb04b516eac64c3ec8)

| | | | | | | | | | | | | | | | | | Now, whenever we update bison's copy of gnulib, bootstrap will update itself the next time it's run. * bootstrap: Copy from latest gnulib for bootstrap_sync support. * bootstrap.conf (bootstrap_sync): Set to true. * gnulib: Update to latest so bootstrap is in sync now. (cherry picked from commit 10bae98af27edbb84a06d82a20a63ad7a0cca688)

If someone needs these files, they can resurrect them. * .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore: * m4/.gitignore, po/.gitignore, runtime-po/.gitignore: Omit leading '/', since bootstrap omits it. Adjust file names to match current contents better. * bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook installed just for us. * bootstrap.conf (excluded_files): Don't exclude codeset.m4, glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now needed somehow. Don't have time to look into why. (gnulib_modules): Change malloc to malloc-gnu. Do we really assume the GNU malloc behavior, where malloc (0) != NULL unless we're out of storage? If not, we can omit malloc-gnu; but for now I left it in to be safe. (vc_ignore): Remove. * README-hacking: Renamed from HACKING, since gnulib bootstrap now uses that convention.

| * portability: fix several issues with M4 subprocess.Joel E. Denny2010-02-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | do not ignore errors like ENOSPC,EIO when writing to stdoutJim Meyering2012-01-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | build: generalize etc/prefix-gnulib-mkJim Meyering2012-01-231-1/+1
| | | | | | | | | | | | | | | | | | 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.

* | build: manually update bootstrap from gnulib, and adaptJim Meyering2012-01-191-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 "\".
* | maint: get gpl-3.0 from gnulibJim Meyering2012-01-191-1/+1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * bootstrap.conf (gnulib_modules): Add all modules suggested by -DGNULIB_POSIXCHECK. * src/files.c (file_name_split) * src/getargs.c (getargs) * src/location.c (boundary_set_from_string) * src/output.c (output_skeleton) * src/parse-gram.y (prologue_declaration) * src/scan-gram.l (handle_syncline) * src/symtab.c (symbol_new): Use mbschr and mbsrchr instead of strchr and strrchr. In the cases of command-line options, file names, and thus locations, functionality may be improved. In the case of symbol names, there should be no functional difference as all characters are ASCII, so the intended benefit is just warning suppression.

If someone needs these files, they can resurrect them. * .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore: * m4/.gitignore, po/.gitignore, runtime-po/.gitignore: Omit leading '/', since bootstrap omits it. Adjust file names to match current contents better. * bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook installed just for us. * bootstrap.conf (excluded_files): Don't exclude codeset.m4, glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now needed somehow. Don't have time to look into why. (gnulib_modules): Change malloc to malloc-gnu. Do we really assume the GNU malloc behavior, where malloc (0) != NULL unless we're out of storage? If not, we can omit malloc-gnu; but for now I left it in to be safe. (vc_ignore): Remove. (gnulib_mk_hook): New function. * README-hacking: Renamed from HACKING, since gnulib bootstrap now uses that convention.

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/local.mk (lib_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.
