* eval: Don't error out in -ls if the time overflowsTavian Barnes2025-02-071-19/+30
|
* ioq: Use getppid() for the heavy NOP syscallTavian Barnes2025-02-061-1/+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 Barnes2025-02-061-2/+2
| | | | | | | | | 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/

* ioq: Rewrite the spin loop to avoid a warningTavian Barnes2025-02-031-4/+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.

* xspawn: Unblock signals between fork() and exec()Tavian Barnes2025-01-181-2/+15
| | | | | | Otherwise the child process runs with all signals blocked. Fixes: 423cfa4 ("xspawn: Mask signals before fork()")

* sighook: Always re-raise faults on macOSTavian Barnes2024-12-221-0/+7
| | | | | | | | | | 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: New sanitize_resize() functionTavian Barnes2024-12-162-16/+33
| | | | | This wraps __sanitizer_annotate_contiguous_container() to give byte-precise tracking of usable allocation sizes with ASan.
* sanity: Get rid of sanitize_ignore()Tavian Barnes2024-12-162-11/+6
| | | | | It's probably nicer to avoid evaluating expensive arguments when not sanitizing, rather than relying on the optimizer to clean them up.
* ioq: Refactor ioq_ring_probe_flags()Tavian Barnes2024-12-041-11/+13

* ioq: Try spinning before blocking in ioq_slot_wait()Tavian Barnes2024-12-031-1/+17
|
* ioq: Submit and pop requests in batchesTavian Barnes2024-12-033-17/+42
| | | | | The new ioq_submit() function is now necessary to call to ensure the pending request batch is flushed.
* ioq: Add more io_uring setup flagsTavian Barnes2024-12-031-20/+55
|
* ioq: Refactor io_uring submission logicTavian Barnes2024-12-031-94/+145
|
* ioq: Use ioq_batch for both pushing and poppingTavian Barnes2024-12-031-47/+84
|
* ioq: Add a hash function between slots and monitorsTavian Barnes2024-12-031-1/+11
| | | | | | This helps avoid situations where multiple waiters block on different slots using the same monitor, which happened more often than expected due to correlations caused by batching.
* ioq: Prefetch pointers before popping themTavian Barnes2024-12-032-8/+10
| | | | | Also, cache-align struct ioq_ent to avoid false sharing when two workers are handling neighbouring requests.
* ioq: Add an ioq_nop() operation for benchmarkingTavian Barnes2024-12-023-0/+62

|
* sighook: Return instead of re-raising for faultsTavian Barnes2024-11-231-5/+11
| | | | | | | | | | | This makes the death look exactly like it would if we didn't handle the signal at all. Coredumps will point at the right instruction, segfaults will get logged in dmesg again, etc. Technically POSIX says this is undefined, but if we get a fault, we've already done something undefined anyway ;) Link: https://github.com/rust-lang/rust/issues/26458
* sighook: Check for SA_RESTART before using itTavian Barnes2024-11-231-1/+7
| | | | QNX doesn't support SA_RESTART.

* color: Squelch a -Wmaybe-uninitialized warning on non-LTO buildsTavian Barnes2024-11-201-1/+1
|
* ioq: Check for io_uring_register_iowq_max_workers() before using itTavian Barnes2024-11-111-0/+3
| | | | | | | This allows us to build against liburing as old as version 2.0, which is apparently shipped by the latest Amazon Linux distribution. Fixes: https://github.com/tavianator/bfs/issues/147
* sanity: Don't mark memory uninit in sanitize_{alloc,free}()Tavian Barnes2024-11-022-9/+11
| | | | | We might want to change the size of an allocated region without changing which bytes are initialized.
* alloc: Stop supporting pathological flexible array ABIsTavian Barnes2024-11-022-18/+29

* alloc: Add macro versions of alignment utilsTavian Barnes2024-11-021-3/+12
|
* trie: Fix varena_free() with wrong sizeTavian Barnes2024-11-021-8/+8
| | | | | | | In trie_remove(), clearing the bit before trie_node_collapse() causes us to free the old node with size 1 instead of 2, putting it on the wrong freelist. This is technically safe with the current arena implementation, but not intentional.
* alloc: Don't require size % align == 0Tavian Barnes2024-11-022-30/+19
| | | | | | | | | 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 Frankowski2024-10-311-1/+1
| | | | | | | | | | | 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")
