* opt: Add a missing NULL check in lift_andor_not()Tavian Barnes2024-08-121-0/+4
| | | | | The annotation visitor probably can't fail, but we might as well check consistently.
* opt: Warn about ignored expressions after dangerous actionsTavian Barnes2024-08-123-25/+79
| | | | | | For example, `bfs -delete -type f` is almost certainly a mistake. Link: https://savannah.gnu.org/bugs/?65895
* opt: Copy data flow back up from the nested context in optimize()Tavian Barnes2024-08-121-2/+11
| | | | | | | | This fixes warnings on commands like `bfs -exclude -true` or `bfs -exclude -type f -type f`, because the data flow is properly shared between the -exclude expression and the main one. Fixes: 4a36bb9 ("expr: Make expressions variadic")
* sighook: Disable semaphores on NetBSDTavian Barnes2024-08-111-1/+2
|
* bfstd: New sysoption() macro to check for POSIX option runtime supportTavian Barnes2024-08-095-39/+84
| | | | | | | | | | POSIX allows optional features to be supported at compile time but not necessarily at run time by defining _POSIX_OPTION to 0 and requiring users to check sysconf(_SC_OPTION) > 0. The new sysoption() macro simplifies the check. sighook() and bfs_spawn() now check for conditional runtime support for the relevant POSIX options.
* xtime: Remove xgettime()Tavian Barnes2024-08-095-39/+10
| | | | clock_gettime() is available everywhere by now.
* prelude: s/fallthru/_fallthrough/ for consistency with other attributesTavian Barnes2024-08-095-15/+15

* bar: Hide the bar unless the TTY is tall enoughTavian Barnes2024-08-071-13/+23

* docs/CHANGELOG: Add some new changesTavian Barnes2024-08-021-0/+6
|
* parse: Take umask into account in parse_mode()Tavian Barnes2024-08-027-10/+43
| | | | | | | POSIX 2024 clarified that find(1) is meant to work exactly like chmod(1) here, so for modes like +rw,-x with no "who" specified, apply the umask. Link: https://www.austingroupbugs.net/view.php?id=1392
* tests: Add more files to perms/Tavian Barnes2024-08-0222-103/+333
|
* parse: Fix names in parse_mode()Tavian Barnes2024-08-021-14/+14
| | | | | | | Commit 9c6e4ce ("parse: s/parser_state/bfs_parser/") was a little to overzealous in replacing "state" with "parser", resulting in the tortured phrase "parser machine parser" instead of "state machine state".
* Update opengroup.org links to POSIX 2024Tavian Barnes2024-08-024-9/+9
|
* Revert "typo: Raise the insert/delete cost"Tavian Barnes2024-08-021-1/+1
| | | | | | | That was a little too aggressive, with -alse suggesting -size instead of -false. This reverts commit 0d6822ee71c1f60c8003e13ab149501e586f9ae6.
* bar: #include <unistd.h> for ioctl() on IllumosTavian Barnes2024-08-011-0/+1

* xspawn: Fix error message if pthread_sigmask() failsTavian Barnes2024-07-271-2/+2
|
* 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.
