Denny + + 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 Joel E. Denny + + 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 + . + + There were also problems with the test suite livelocking on + Tru64 5.1b. Reported by Didier Godefroy at + . + 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. + +2010-02-04 Joel E.

Denny + + 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.
