* parse: Handle multiple flags at once like -LEXO2Tavian Barnes2024-06-031-26/+138
| | | | | | | | | | | | | | | | | | | | | The POSIX Utility Syntax Guidelines specify that flag groups like -HL should be handled like -H -L. GNU find doesn't support grouping flags in this way, but BSD find does. To avoid conflicts with non-flag primaries, for now we require at least one flag in a group to be a capital letter. That is, we support things like -Lds but not -ds. We also do not support -fPATH (without a space) as it would conflict with -follow, -fprint, etc. It is impossible to be compatible with both GNU and BSD find here: user@gnu$ find -follow link link/file ... user@bsd$ find -follow find: ollow: No such file or directory Link: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap12.html

* xtime: Call tzset() from main() instead of lazilyTavian Barnes2024-03-071-6/+6
| | | | | | | | | | | | | POSIX specifies[1] that If a thread accesses tzname, daylight, or timezone directly while another thread is in a call to tzset(), or to any function that is required or allowed to set timezone information as if by calling tzset(), the behavior is undefined. So calling it lazily from arbitrary threads is risky. [1]: https://pubs.opengroup.org/onlinepubs/9699919799/functions/tzset.html
* sanity: Don't use self-init for uninit()Tavian Barnes2024-02-121-4/+4
| | | | | | | | | | | Self-initialization like bool ret = ret; is a GCC trick to suppress uninitialized variable warnings, but it's not actually well-defined, and will trip a recent enough MemorySanitizer: src/eval.c:1088:13: runtime error: load of value 128, which is not a valid value for type 'bool'
* ctx: Fill in ctx->threads earlierTavian Barnes2024-02-061-4/+2
|
* expr: Make expressions variadicTavian Barnes2024-01-071-48/+25
| | | | | | | | | 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.
