* opt: Track data flow information about predicatesTavian Barnes2020-05-227-37/+280
| | | | | | | | | | This allows us to optimize things like -sparse -o -not -sparse <==> -true and -sparse -a -not -sparse <==> -false

* Makefile: Don't use target-specific variables for configuration targetsTavian Barnes2020-03-241-17/+28
| | | | | | | | | | | | | | | | | | | In things like release: CFLAGS := ... release: bfs CFLAGS is only set for the dependencies of release, so $ make release check doesn't set CFLAGS for tests/mksock. For the same reason, $ make asan ubsan was broken, because only the asan flags would be set for bfs. Fix it by checking MAKECMDGOALS for those targets manually instead.
* Makefile: Add asan, msan, ubsan targetsTavian Barnes2020-03-231-3/+12

* Makefile: Use --sudo for every distcheck testTavian Barnes2020-03-231-11/+10

* opt: Avoid dangling pointers in de_morgan()Tavian Barnes2020-03-231-5/+7
| | | | | | | | If optimize_{and,or}_expr() relocates expr, we need to update the parent expr or else we might return garbage. It seems impossible to actually trigger this bug right now, since the {and,or} optimizations are symmetric, but it could be hit if the simplifications in de_morgan() expose more information than was known previously.

* passwd: Cache the user/group tablesTavian Barnes2020-02-298-35/+471
| | | | | | | | | | | | | | | | | | | | | | 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.

* eval: Irregular files aren't emptyTavian Barnes2020-02-143-2/+20
| | | | | GNU find's -empty returns false for devices, sockets, etc., even though their st_size is 0. Match that behaviour.
* time: Implement xtimegm() without mktime()Tavian Barnes2020-02-131-32/+99
| | | | Using setenv("TZ") is ugly and adds unnecessary failure paths.

* parse: Handle 1969-12-31T23:59:59ZTavian Barnes2020-02-135-19/+66
| | | | | mktime() returns -1 on error, but also for one second before the epoch. Compare the input against localtime(-1) to distinguish those cases.

* 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.
