* tests: Don't clobber inherited FDsTavian Barnes2024-02-0112-52/+46
| | | | | Rather than attempting to close any unexpected FDs, just count them and adjust our ulimit -n calls to account for them.
* tests: Use variable redirections to dup std{out,err}Tavian Barnes2024-02-013-29/+18
| | | | | | | | | | | Previously, we hardcoded file descriptors 3 and 4 for duplicating stdandard output/error respectively. In preparation for keeping inherited FDs open, switch to using bash's variable redirection feature to dynamically assign FDs. This feature is only available from bash 4.1 onwards, so this marks the end of our support for bash 3. macOS users will need to install a modern bash version to run our tests.
* ci/freebsd: Use the system compilerTavian Barnes2024-02-011-2/+1
| | | | Release builds work now on FreeBSD 14.
* bftw: Always block in bftw_pop_dir() with multiple threadsTavian Barnes2024-02-011-11/+22
|
* bftw: Don't immediately pin open directoriesTavian Barnes2024-02-011-4/+5
| | | | | | | It is undesirable to close a directory that we haven't read yet to free up cache capacity, but it's worse to fail to open the next directory because too many upcoming directories are pinned. This could happen when sorting, because then we can't prioritize the already-opened ones.
* bftw: Allow forcing bfs_dir allocation from the main threadTavian Barnes2024-02-011-12/+35
| | | | | | | | | When sorting, we can be forced to pop an unopened directory. If enough other directories are already open, that can lead to ENOMEM when we try to open it synchronously. To avoid this, force allocations from the main thread to be attempted even if they would go over the limit. Also, fix the accounting in bftw_allocdir() if allocation fails.
* bftw: Kill trivial bftw_queue_balance() helperTavian Barnes2024-02-011-7/+2

* bfstd: Don't shadow FreeBSD's fflags_tTavian Barnes2024-02-011-4/+4
|
* bftw: Actually stop if the callback returns BFTW_STOPTavian Barnes2024-01-313-1/+6
| | | | | | Otherwise, bftw_ids() or bftw_eds() might keep going! Fixes: 5f16169 ("bftw: Share the bftw_state between iterations of ids/eds")
* opt: Charge eval_flags() for a stat() callTavian Barnes2024-01-311-0/+1
|
* bftw: Optimize -s -j2 searchesTavian Barnes2024-01-311-2/+1
| | | | | Maintaining balance and strict ordering at the same time forces too much work onto the main thread.
* bftw: Use a bftw_queue for files tooTavian Barnes2024-01-311-26/+31

* bftw: New bftw_queue abstractionTavian Barnes2024-01-311-74/+292

* tests/posix: Avoid catastrophic backtrackingTavian Barnes2024-01-172-11/+2
| | | | | | Using -path 'deep/*/*/.../*' to simulate -mindepth 18 falls off a performance cliff on systems that use backtracking for fnmatch(). This was observed on macOS 12.4. Instead, just use -type f.
* xspawn: Check for _POSIX_SPAWN in bfs_spawn_addfchdir()Tavian Barnes2024-01-171-1/+1
|
* fsade: Mark bfs_acl_tag_type() as maybe_unusedTavian Barnes2024-01-171-0/+1
| | | | | It's not used on at least macOS, which doesn't have ACL_{USER,GROUP}_OBJ or ACL_OTHER.
* tests: Properly filter escape sequences with --verbose=testsTavian Barnes2024-01-131-1/+1
|
* ioq: Use the negative errno conventionTavian Barnes2024-01-135-26/+33
|
* bfstd: New {error,errno}_is_like() functionsTavian Barnes2024-01-136-35/+45
| | | | | | | We used to have is_nonexistence_error() to consistently treat ENOENT and ENOTDIR the same. Recently, we started considering EFAULT the same as ENAMETOOLONG on DragonFly BSD to work around a kernel bug. Unify both of these behind a more generic interface.

* expr: Make expressions variadicTavian Barnes2024-01-078-890/+1719
| | | | | | | | | Rather than only unary/binary expressions, we now support an arbitrary number of children. The optimizer has been re-written almost completely and now supports optimal reordering of longer expression chains, rather than just arm-swapping. Fixes #85.

* Work around DragonFly BSD kernel bugTavian Barnes2024-01-042-1/+19
| | | | | | | | | DragonFly's x86_64 assembly implementation of copyinstr() checks the wrong pointer when deciding whether to return EFAULT or ENAMETOOLONG, causing it to always return EFAULT for overlong paths. Work around it by treating EFAULT the same as ENAMETOOLONG on DragonFly. Link: https://twitter.com/tavianator/status/1742991411203485713
