* Revert "bit: Implement a branchless has_single_bit()"Tavian Barnes2023-11-111-2/+1
| | | | | | Doesn't work for the highest bit due to overflow. This reverts commit 208376ef99da243545efcd6fb02d3469b4c068ed.
* Initial support for Cosmopolitan LibcTavian Barnes2023-11-105-3/+33
|
* exec: Don't do setrlimit() in the parentTavian Barnes2023-11-101-22/+4
| | | | | | | | | This was hacky, but it's also broken because it can make posix_spawn() fail with EMFILE, as happens on at least musl. Fixes: 7d69fef6a0b80ad57acde7bac8a22b83531fec0d Link: https://www.austingroupbugs.net/view.php?id=603 Link: https://sourceware.org/bugzilla/show_bug.cgi?id=31049

* list: Simplify slist_remove_impl()Tavian Barnes2023-11-091-4/+4
| | | | We now assume that all-bits-zero is a null pointer, so memset is fine.

|
* parse: Reject -{exec,ok}dir if $PATH contains a relative pathTavian Barnes2023-11-071-0/+26
| | | | This matches the behaviour of GNU find.
* xspawn: Do $PATH resolution up-frontTavian Barnes2023-11-071-21/+19
| | | | | | | | | posix_spawnp() is typically implemented like execvp(), i.e., by repeatedly trying execv() with each $PATH component until it succeeds. This is much slower than resolving the executable path up-front and then calling execv() once, so do that. Fixes: https://github.com/tavianator/bfs/pull/127#issuecomment-1795095126
* Treat NO_COLOR="" the same as unsetTavian Barnes2023-11-061-1/+2
| | | | | | | | | | | | | | The docs say > Command-line software which adds ANSI color to its output by default > should check for a NO_COLOR environment variable that, when present > and not an empty string (regardless of its value), prevents the > addition of ANSI color. but we were not checking for the empty string.

| | | | Android doesn't provide a getdents() wrapper, so use the syscall.

|
* bftw: Make sure we don't close a directory while we unwrap itTavian Barnes2023-10-121-2/+6
| | | | | | | bftw_cache_reserve() can lead to bftw_cache_pop(), which could close the directory we're trying to unwrap! If that happened, we would try dup_cloexec(-1), which would fail with EBADF, so there was no observable bug. But it's better to avoid the whole situation.
* bftw: Fix to_close list corruption with !BFS_USE_UNWRAPDIRTavian Barnes2023-10-121-6/+13
| | | | | | | | | | It's possible for pincount to drop to zero, then get incremented and drop back to zero again. If this happens, we shouldn't add it to the to_close list twice. This should fix the intermittent hang on the macOS CI. Fixes: 815798e1eea7fc8dacd5acab40202ec4d251d517

|
* bftw: Fix unbuffered depth-first searchesTavian Barnes2023-10-121-15/+41
| | | | | | | | | | | | | | | bftw() implements depth-first search by appending files to a batch, then prepending the batch to the queue. When we switched to separate file/ directory queues, this was only implemented for the file queue. Unbuffered searches don't use the file queue, so they were all breadth- first in practice. This meant that iterative deepening (-S ids) was actually "iterative deepening *breadth*-first search," a horrible strategy with no advantage over regular breadth-first search. Now it performs iterative deepening *depth*-first search, which at least limits its memory consumption. Fixes: c1b16b49988ecff17ae30978ea14798d95b80018
