* 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: Actually stop if the callback returns BFTW_STOPTavian Barnes2024-01-311-1/+1
| | | | | | Otherwise, bftw_ids() or bftw_eds() might keep going! Fixes: 5f16169 ("bftw: Share the bftw_state between iterations of ids/eds")

* 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.

* 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.
* ioq: Use the negative errno conventionTavian Barnes2024-01-135-26/+33
|
* bfstd: New {error,errno}_is_like() functionsTavian Barnes2024-01-135-21/+42
| | | | | | | 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.
* config: Disable sys/acl.h on illumosTavian Barnes2024-01-091-1/+1
| | | | | | Their ACL API is quite a bit different from most. Link: https://illumos.org/man/2/acl
* eval: Check for xbasename() allocation failureTavian Barnes2024-01-071-1/+8
|
* 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.
* list: New SLIST_HEAD() and SLIST_TAIL() macrosTavian Barnes2024-01-071-3/+40

* Work around DragonFly BSD kernel bugTavian Barnes2024-01-041-1/+13
| | | | | | | | | 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

* config: Disable xattrs on DragonFly BSDTavian Barnes2024-01-031-1/+1
| | | | DragonFly is missing extattr_get_link() and extattr_list_{file,link}().

* bit: Rename bswap{16,32,64}()Tavian Barnes2024-01-031-16/+16
| | | | | NetBSD already defines this in <sys/bswap.h>, so pick names that don't conflict.

* pwcache: Fix uninitialized pointers on OpenBSDTavian Barnes2024-01-021-4/+4
| | | | | | | | | | | | | POSIX specifies that the get{pw,gr}*_r() functions store a NULL pointer to *result on error. However, OpenBSD does not always do this[1][2]: > if (bufsize < GETGR_R_SIZE_MAX) > return ERANGE; Work around it by explicitly initializing ret to NULL.
