* src/timeout.c (main): Use PR_SET_PDEATHSIG to ensure the
child is terminated even if the parent terminates abnormally.
* tests/timeout/timeout-group.sh: Add a case to ensure sending
SIGKILL results in the termination of the monitored command.
* NEWS: Mention the improvement.
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.
* .gitignore: Add /lib/fenv.h to ignore list.
* tests/timeout/timeout-parameters.sh: Use a sleep length of 10s
to be consistent with the pattern where we use this larger time
when it does not slow down a test, but also provides protection
against a hung test, and better avoidance of false failures due
to races on very loaded systems. Also fix the setting of FAIL.
* tests/timeout/timeout-large-parameters.sh: Remove duplicated test.
This handles timeouts like 16777216.000000001 correctly;
formerly the subsecond part of that timeout was ignored.
* bootstrap.conf (gnulib_modules): Add fenv-rounding, signbit.
* src/local.mk (src_timeout_LDADD): Append $(FENV_ROUNDING_LIBM).
* src/timeout.c: Include fenv.h, math.h.
Don’t include xstrtod.h, as xstrtod’s checking now gets in the way.
(parse_duration): Round up when calling cl_strtod.
Check for -1e-1000. Don’t double-round 1e-9.
* tests/timeout/timeout-parameters.sh: Test for -0.1,
-1e-1000, 1e-1000.
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.
