* xspawn: Use _Fork() if availableTavian Barnes2024-07-275-0/+22
| | | | | | | This completes the workaround for bfs_spawn() hanging on FreeBSD with ASan enabled. Link: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=280318

* xspawn: Test the right macro for posix_spawn_..._addfchdir() supportTavian Barnes2024-07-161-1/+1
| | | | | | | | | | This should have been benign (just a performance regression), but FreeBSD has a bug that causes the fork()-based fallback to lock up when ASAN is enabled, due to fork() and dl_iterate_phdr(). This is not a complete workaround for that issue, since the fork() fallback may be used for other reasons. Fixes: 29ddac2 ("config: Check for posix_spawn_file_actions_addfchdir{,_np}()")

* tests: Simplify unit tests with a global variableTavian Barnes2024-07-0711-324/+263
| | | | | It's a little awkward to thread the test result through manually; much easier to just make bfs_check() update a global variable.
* sighook: Replace sigtables with RCU-protected linked listsTavian Barnes2024-07-072-182/+128
| | | | | | | | This fixes an ABA problem where sigdispatch() could think no handlers are registered for a signal even when there are. Link: https://unix.stackexchange.com/a/779594/56202 Fixes: 375caac ("sighook: New utilities for hooking signals")

* configure: Fix VAR=value before --optionTavian Barnes2024-06-181-76/+77
| | | | | | | | | Previously we were not shifting all arguments, leading to $ ./configure CC=gcc --enable-release make: unrecognized option '--enable-release' as the loop would shift the CC=gcc argument instead of --enable-release.

| | | | This avoids extra error reporting from set -e.
* typo: Raise the insert/delete costTavian Barnes2024-06-081-1/+1
| | | | | It should be at least half the max char distance so that we mostly get replacements, not inserts + deletes.

* xspawn: Check X_OK even without $PATH resolutionTavian Barnes2024-06-082-2/+13
| | | | | | | | | | Not all posix_spawn() implementations use errno to report execv() failures from the child process, as that requires either a kernel posix_spawn() implementation or a pipe to pass the error back. This should fix tests/posix/exec_nonexistent on OpenBSD and HPPA. Link: https://buildd.debian.org/status/fetch.php?pkg=bfs&arch=hppa&ver=3.3.1-1&stamp=1717489148&raw=0
