* tests/color: Use /dev/tty over $TTYTavian Barnes9 days1-2/+2
| | | | | | | | | | $TTY is the actual TTY, e.g. /dev/pts/3, which may not be accessible by the current user. This can happen e.g. if the PTY is owned by root, who then does root@host# su user user@host$ ./tests/tests.sh ./tests/color.sh: line 81: /dev/pts/3: Permission denied

* tests: Use $EPOCHSECONDS if it existsTavian Barnes9 days1-2/+7
| | | | | | | Bash 5 adds that special variable, which should be more reliable than the awk trick, which is known to be broken on mawk. Fixes: https://github.com/tavianator/bfs/issues/152
* mtab: Use mount IDs instead of dev_t for bfs_fstype()Tavian Barnes10 days2-0/+29
| | | | | | | | | This fixes -fstype on btrfs subvolumes, which previously reported "unknown" due to their dev_t being potentially different from the mount point. Link: https://savannah.gnu.org/bugs/?50859 Link: https://lwn.net/Articles/866582/
* tests/posix/exec_sigmask: Make portableTavian Barnes12 days1-2/+14
| | | | | | | | The test was Linux-only, and didn't pass on at least mips64el due to a different signal mask size. The new version should be fully portable, but will hang forever on failure. Link: https://buildd.debian.org/status/fetch.php?pkg=bfs&arch=mips64el&ver=4.0.5-1&stamp=1737761227&raw=0
* tests/sighook: Fix Valgrind compatibilityTavian Barnes2025-01-211-39/+43
| | | | | | | | | | | | | | | | | | | | Valgrind does not deliver async signals in a timely manner; by default, it polls for new signals every 1,000 basic blocks. That means we can get SIGALRM delivered after timer_delete(), or kill(SIGSEGV) never delivered after pause(). Fix the timer_delete() issue by reordering the cleanup path. Valgrind always polls pending signals after pthread_sigmask(), so call that between timer_delete() and sigunhook(). Fix the pause() issue by sleeping in a loop instead. Note that --fair-sched=yes is required to avoid starvation of the background thread.

* sighook: Always re-raise faults on macOSTavian Barnes2024-12-221-0/+4
| | | | | | | | | | macOS always fills in si_code for SIG{BUS,ILL,SEGV} as if it were a real hardware fault, so returning from the handler is not guaranteed to re- trigger the signal.

* sanity: Don't mark memory uninit in sanitize_{alloc,free}()Tavian Barnes2024-11-021-10/+34
| | | | | We might want to change the size of an allocated region without changing which bytes are initialized.

|
* alloc: Don't require size % align == 0Tavian Barnes2024-11-021-0/+8
| | | | | | | | | Allowing unaligned sizes will allow us to allocate aligned slabs with additional metadata in the tail without ballooning the allocation size for large alignments.

* color: Handle bfs_check_capabilities error code (-1) in cpath_has_capabilitiesJody Frankowski2024-10-314-0/+42
| | | | | | | | | | | On non-Linux systems, bfs_check_capabilities always returned -1, so cpath_has_capabilities would always return true. If bfs was called with an LS_COLORS containing the `ca` statement, e.g. `ca=30;41`, bfs would color ALL the files. While including the `ca` statement in LS_COLORS on non-Linux systems is unusual, this is not an error and is a valid use-case (e.g. Using GNU ls or lsd). Fixes: 1520d4d3 ("color: Don't color files like directories on ENOTDIR")
* bit: Add bswap() overloads for every primitive typeTavian Barnes2024-10-271-0/+7

* color: Fix an infinite loop colorizing some invalid pathsTavian Barnes2024-10-132-0/+2
| | | | | | | | | | | | | | Previously, given $ touch file $ ln -s file/file notdir $ bfs notdir/file bfs would loop forever when printing the error message, since it expected stripping the trailing slash from "notdir/" to fix the ENOTDIR error, but the broken symlink still gave the same error. Fixes: b4c3201 ("color: Only highlight the trailing slash on ENOTDIR")

|
* sighook: Don't forget to reset list->tail on the last sigpop()Tavian Barnes2024-10-101-0/+7
| | | | | | | This was causing a UAF if we ever unregistered the last hook for a signal and then re-registered one. Fixes: 75b7f70 ("sighook: Make sigunhook() O(1)")

* color: Fix an assertion failure with embedded NUL bytesTavian Barnes2024-10-022-0/+32
| | | | | | | | | | | | | Leading NUL bytes (e.g. `*\0.gz=...`) could cause us to insert a non-prefix-free set of strings into the case-insensitive extension trie, which would lead to crashes like bfs: trie_split@src/trie.c:538: Assertion failed: `key_nibble != rep_nibble` and OOB accesses to trie leaf keys. Fix it by ignoring those extensions, since filenames cannot contain NUL bytes. Fixes: 08030aea ("color: Delay the case_sensitive decision")

|
* opt: Fix an invalid assertion in sink_not_comma()Tavian Barnes2024-09-172-0/+36
| | | | | | | When optimizing -not \( -a , -b \), the child is a comma expression, not the parent. Fixes: 4a36bb9 ("expr: Make expressions variadic")

|
* build: Move feature test macros to prelude.hTavian Barnes2024-08-2812-18/+4
| | | | | | This replaces the explicit CPPFLAGS list in flags.mk with just `-include src/prelude.h`, shortening our compiler command lines and allowing them to be easily documented.

|
* diag: Get rid of bfs_static_assert()Tavian Barnes2024-08-281-31/+37
| | | | | In most cases, it's not too annoying to specify a message. For tests/bit.c, we can manually polyfill the 1-argument version.

* parse: Take umask into account in parse_mode()Tavian Barnes2024-08-024-2/+21
| | | | | | | 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
