|
* trie: Make nibble indices big-endianTavian Barnes3 days2-7/+11
| | | | Otherwise the order doesn't match lexicographical order on bytes.

|
* trie: Micro-optimize trie_representative()Tavian Barnes5 days1-4/+5
| | | | | popcount(map & (bit - 1) & mask) has a longer critical path than popcount(map & (bit - 1)) & mask.

|
* 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
* eval: Don't error out in -ls if the time overflowsTavian Barnes9 days2-19/+34
|
* 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
* ioq: Use getppid() for the heavy NOP syscallTavian Barnes10 days1-1/+1
| | | | | | | | getpid() could hypothetically be cached (and glibc used to do it). getppid() can't be, because the parent could die and reparent the child to init. Link: https://lore.kernel.org/linux-mm/Z58dIOGlJ3grsAge@casper.infradead.org/
* mtab: Use mount IDs instead of dev_t for bfs_fstype()Tavian Barnes10 days3-2/+31
| | | | | | | | | 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/
* stat: Expose mount IDs from statx()Tavian Barnes10 days3-2/+40

* 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
* ioq: Rewrite the spin loop to avoid a warningTavian Barnes13 days1-4/+3
| | | | | | | | | | | | With some GCC versions, --enable-ubsan leads to this warning: src/ioq.c: In function ‘ioq_slot_wait’: src/ioq.c:287:17: warning: ignoring loop annotation 287 | for (int j = 0; j < (1 << i); ++j) { | ^~~ presumably due to UBSan rewriting the shift to check for overflow. Work around this by precomputing the iteration count.

* 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 Barnes2024-12-222-0/+11
| | | | | | | | | | 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.
