* prelude: Remove unused __GLIBC_PREREQ() polyfillTavian Barnes2024-05-071-4/+0
|
* stat: Remove __GNU__ guardTavian Barnes2024-05-071-1/+1
| | | | | The number of people running bfs on Hurd with an outdated glibc version is vanishingly small (I hope).
* stat: Prefer fstat(fd) to fstatat(fd, "", AT_EMPTY_PATH)Tavian Barnes2024-05-071-19/+13
| | | | | | | | | This lets us get rid of the runtime probe for AT_EMPTY_PATH support, and should be more efficient anyway. We still use statx(fd, "", AT_EMPTY_PATH) if available. Link: https://lore.kernel.org/linux-fsdevel/CAHk-=wiYnnv7Kw7v+Cp2xU6_Fd-qxQMZuuxZ61LgA2=Gtftw-A@mail.gmail.com/

* ioq: Fix uninitialized values in ioq_create() cleanup pathTavian Barnes2024-04-241-4/+1
| | | | | | | | I switched from ZALLOC_FLEX() to ALLOC_FLEX() in hopes that msan would catch uninitialized values in ioq_thread_create(), but in doing so, forgot to initialize all fields before the first goto fail. Fixes: f64f76b ("ioq: Copy ring_ops from the previous thread")
* printf: Check dynamic format strings more carefullyTavian Barnes2024-04-242-41/+48

|
* opt: Add missing NULL check in visit_shallow()Tavian Barnes2024-04-241-1/+5
| | | | | visit_shallow() should propagate NULL, but look_up_visitor() dereferences expr to know which visitor to return.
* dstring: Add missing va_end() to dstrvcatf() error pathTavian Barnes2024-04-241-0/+1

* config: Check for extattr_{get,list}_{file,link}()Tavian Barnes2024-04-222-11/+53
| | | | This lets us implement -xattr on DragonFly BSD.

* xspawn: Fix $PATH resolution on NetBSD 10Tavian Barnes2024-04-091-2/+2
|
* config: Allow inlining allocator functionsTavian Barnes2024-03-281-1/+1
| | | | | GCC disables inlining on custom allocator/deallocator pairs, so that they can be matched up accurately in stack traces.
* xspawn: Fix bfs_resolve_late() error reportingTavian Barnes2024-03-271-8/+2
|
* xspawn: Don't use posix_spawnp() on macOSTavian Barnes2024-03-271-1/+33
| | | | | | | | On macOS, posix_spawnp() resolves the executable against the $PATH *before* the file_actions are applied, contrary to the upcoming POSIX wording [1] for posix_spawn_file_actions_addfchdir(). [1]: https://www.austingroupbugs.net/view.php?id=1208#c4830
* xspawn: Refactor $PATH resolutionTavian Barnes2024-03-271-81/+240
| | | | | | | | | Technically, we should be resolving executables *after* applying the file actions. It's only safe to resolve earlier if $PATH contains no relative entries, or if there are no fchdir() actions. The new implementation resolves as early as possible, deferring to posix_spawnp() if necessary for correctness.
* xspawn: Implement bfs_spawn_addopen()Tavian Barnes2024-03-272-3/+67
|
* bfstd: Escape ASCII tildesTavian Barnes2024-03-261-1/+1
| | | | | | | | The POSIX spec [1] lists some characters that may need to be escaped. Unfortunately, the document uses ˜ (U+02DC SMALL TILDE) instead of ~ (U+007E TILDE), and I copy-pasted from it. [1]: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_02
