+

+
+ 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/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.
+ (Conflicting output files: -o foo.y): Update expected output.
+ * tests/skeletons.at (Fatal errors but M4 continues producing
+ output): New test group.
+
