This behavior was depended on in our trap_sigpipe_or_skip_ helper,
and now that we're handling all terminating signals, we should
consistently honor their ignored signal dispositions.
* NEWS: Mention the change in behavior, especially in regard
to shell background jobs.
* src/timeout.c (sig_needs_handling): A new helper that return TRUE,
for --signal, SIG_ALRM, or non ignored signals.
(cleanup_install): Filter handled signals with the helper.
(block_cleanup_and_chld): Likewise.
* tests/timeout/timeout-group.sh: Adjust to use the now required
`env --default-signal=...` wrapper to reset (auto) ignored signals.
Also change the termination signal from SIGINT to SIGUSR1
to generalize the test signals not specially handled by the shell,
and newly handled by timeout(1).
* tests/timeout/timeout.sh: Add a test case for SIGPIPE
to ensure the ignored signal disposition is honored.
* src/timeout.c (term_sig): A new global list of all signals
whose default disposition is to terminate the process.
(install_cleanup): Iterate over the TERM_SIG list, rather than
installing the handler for a specific subset.
(block_cleanup_and_chld): Likewise.
* tests/timeout/timeout.sh: Add a test case for SIGPIPE.
* NEWS: Mention the bug fix.
Update to latest gnulib with new copyright year.
Run "make update-copyright" and then...
* gnulib: Update included in this commit as copyright years
are the only change from the previous gnulib commit.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* tests/sample-test: Adjust to use the single most recent year.
* src/timeout.c (usage): Fix typo of period with comma.
* tests/timeout/timeout.sh: Only test a single option variant,
as tests/misc/usage_vs_getopt.sh suffices for basic option validation.
* src/timeout.c: Support -f and -p short options, corresponding to
--foreground and --preserve-status respectively. This adds
compatability with POSIX 2024 and OpenBSD.
(usage): Separate translations, and reorder the option descriptions.
* doc/coreutils.texi (timeout invocation): Adjust accordingly,
and also reorder the option descriptions alphabetically.
* tests/timeout/timeout.sh: Also test short option variants.
Update to latest gnulib with new copyright year.
Run "make update-copyright" and then...
* gnulib: Update included in this commit as copyright years
are the only change from the previous gnulib commit.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Manually update copyright year,
until we fully sync with gnulib at a later stage.
* tests/sample-test: Adjust to use the single most recent year.
