* -perm: Use +t instead of ug+tTavian Barnes2021-01-131-2/+4
| | | | | | | | | The chmod spec says that ug+t is unspecified, and only +t or a+t is guaranteed to actually set the sticky bit. In practice GNU tools respect o+t as well, but ignore u+t/g+t. Fix the implementation to match GNU, and only test the POSIX required parse.

| | | | Fixes #8.

|
* opt: Track data flow information about predicatesTavian Barnes2020-05-221-2/+2
| | | | | | | | | | This allows us to optimize things like -sparse -o -not -sparse <==> -true and -sparse -a -not -sparse <==> -false

|
* passwd: Cache the user/group tablesTavian Barnes2020-02-291-6/+44
| | | | | | | | | | | | | | | | | | | | | | This is a significant optimization for conditions that need these tables: Benchmark #1: ./bfs ~/code/linux -nouser >/dev/null Time (mean ± σ): 232.0 ms ± 2.5 ms [User: 44.3 ms, System: 185.0 ms] Range (min … max): 228.7 ms … 238.7 ms 12 runs Benchmark #2: ./bfs-1.6 ~/code/linux -nouser >/dev/null Time (mean ± σ): 1.050 s ± 0.012 s [User: 544.2 ms, System: 500.0 ms] Range (min … max): 1.025 s … 1.063 s 10 runs Benchmark #3: find ~/code/linux -nouser >/dev/null Time (mean ± σ): 1.040 s ± 0.012 s [User: 533.6 ms, System: 500.6 ms] Range (min … max): 1.017 s … 1.054 s 10 runs Summary './bfs ~/code/linux -nouser >/dev/null' ran 4.48 ± 0.07 times faster than 'find ~/code/linux -nouser >/dev/null' 4.52 ± 0.07 times faster than './bfs-1.6 ~/code/linux -nouser >/dev/null'
* parse: Give -ls and -fls an ephemeral FD for getpwuid()/getgrgid()Tavian Barnes2020-02-291-0/+2
| | | | | | Similar to 9009456c, those functions may open /etc/{passwd,group}, so they need an FD available. Right now, -ls on large trees eventually starts printing numeric IDs instead of usernames/group names.
* parse: Don't return success for invalid parse_int() calls with -DNDEBUGTavian Barnes2020-02-251-2/+2
|
* time: Split out time-related functions from utilTavian Barnes2020-02-131-145/+14
|
* parse: Handle 1969-12-31T23:59:59ZTavian Barnes2020-02-131-13/+14
| | | | | mktime() returns -1 on error, but also for one second before the epoch. Compare the input against localtime(-1) to distinguish those cases.
* Implement -{a,B,c,m,}sinceTavian Barnes2020-02-121-20/+52
|
* parse: Set tm_isdst to -1Tavian Barnes2020-02-121-1/+3
| | | | | This is required by POSIX to ensure the mktime() determines itself whether DST is in effect.
* parse: Work around missing `timezone` on FreeBSDTavian Barnes2020-02-121-0/+5
| | | | | FreeBSD has a function timezone() that conflicts with the global variable, despite that being specified by POSIX. Use tm_gmtoff instead.
* Implement explicit reference times (-newerXt)Tavian Barnes2020-02-111-3/+177
|
* parse: Add a missing NULL check for trie_insert_mem()Tavian Barnes2020-01-221-0/+5
|
* Update documentation for the -mount/-xdev revertTavian Barnes2019-09-141-1/+2
|
* parse: Don't treat -mount differently from -xdev yetTavian Barnes2019-09-111-1/+8
| | | | | | | | The new POSIX version with -mount isn't out yet, so there's no point in conforming to a non-existent document while breaking compatibility with GNU find, which hasn't changed yet either. But a warning is added for the future incompatibility. This patch can be reverted to re-enable the feature.
* darray: New dynamic array libraryTavian Barnes2019-08-291-16/+5

* Make -mount and -xdev documentation alphabeticalTavian Barnes2019-07-051-3/+3
|
* Make -mount and -xdev do different thingsTavian Barnes2019-07-041-13/+38
| | | | | | | | | POSIX now says -mount should skip the whole mount point, while -xdev should only skip its descendents. C.f. http://austingroupbugs.net/view.php?id=1133 C.f. https://savannah.gnu.org/bugs/?42318 C.f. https://savannah.gnu.org/bugs/?54745
