* configure: Use --with/--without for librariesTavian Barnes2024-05-245-25/+25

* opt: Don't raise RLIMIT_NOFILE if it would prevent using posix_spawn()Tavian Barnes2024-05-234-0/+22
| | | | | | | | | | If we raise RLIMIT_NOFILE, we have to lower it before calling exec() for compatibility with select(). If posix_spawn() doesn't support that, we fall back to fork(), which is quite a bit slower. Therefore, if we're going to exec() on most files, it's better to keep RLIMIT_NOFILE the same to avoid the fork() cost, even though it makes bftw() somewhat slower.

|
* dir: Add support for posix_getdents()Tavian Barnes2024-05-171-4/+12
| | | | | | | | This will be added to the next POSIX standard, and is already implemented in musl. Link: https://www.austingroupbugs.net/view.php?id=697 Link: https://git.musl-libc.org/cgit/musl/commit/?id=1b0d48517f816e98f19111df82f32bfc1608ecec
* Cast AT_FDCWD to int for comparisonsTavian Barnes2024-05-175-7/+7
| | | | | Some platforms define AT_FDCWD to a constant like 0xFFFAFDCD that gets typed as an unsigned int.
* diag: New helpers to include xstrerror(errno) automaticallyTavian Barnes2024-05-175-6/+51

* stat: Support __st_birthtim on OpenBSDTavian Barnes2024-05-161-0/+3

* bar: Use atsigexit() to reset the barTavian Barnes2024-05-161-132/+47
|
* sighook: New utilities for hooking signalsTavian Barnes2024-05-163-0/+674
| | | | This allows multiple hooks to be installed for a single signal.
* atomic: Add a spin_loop() hintTavian Barnes2024-05-151-0/+14
|
* atomic: Add atomic_{thread,signal}_fence() wrappersTavian Barnes2024-05-151-0/+19
|
* xspawn: Mask signals before fork()Tavian Barnes2024-05-151-8/+29
| | | | This prevents signal handlers from running in the child before execve().
* bar: Make SIGWINCH move the cursor out of the barTavian Barnes2024-05-151-23/+16
|
* bar: Defend bfs_bar::fd against signal handler racesTavian Barnes2024-05-091-31/+102
| | | | | This is not currently a problem because bfs_bar_hide() is only ever called while single-threaded, but we might as well program defensively.
* dstring: Make dstrprintf() return dchar *Tavian Barnes2024-05-082-4/+4
|
* prelude: Kill #include <sys/param.h>Tavian Barnes2024-05-071-7/+0
| | | | We don't check for `BSD` anymore.
* build: Check for 1- and 2-argument getmntent() variantsTavian Barnes2024-05-071-2/+2
|
* build: Add a check for getmntinfo()Tavian Barnes2024-05-071-2/+1
|
* mtab: Fix getmntinfo() error checkTavian Barnes2024-05-071-1/+1
| | | | The man pages all say "if an error occurs, zero is returned"
* build: Add checks for strtofflags() and string_to_flags()Tavian Barnes2024-05-071-7/+9
|
* 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/

* config: Add BFS_USE_LIB* to config.h instead of CPPFLAGSTavian Barnes2024-04-251-0/+1
|
* 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
