* xspawn: Don't use posix_spawnp() on macOSTavian Barnes2024-03-271-1/+33
| | | | | | | | On macOS, posix_spawnp() resolves the executable against the $PATH *before* the file_actions are applied, contrary to the upcoming POSIX wording [1] for posix_spawn_file_actions_addfchdir(). [1]: https://www.austingroupbugs.net/view.php?id=1208#c4830
* xspawn: Refactor $PATH resolutionTavian Barnes2024-03-271-81/+240
| | | | | | | | | Technically, we should be resolving executables *after* applying the file actions. It's only safe to resolve earlier if $PATH contains no relative entries, or if there are no fchdir() actions. The new implementation resolves as early as possible, deferring to posix_spawnp() if necessary for correctness.

* bfstd: Escape ASCII tildesTavian Barnes2024-03-261-1/+1
| | | | | | | | The POSIX spec [1] lists some characters that may need to be escaped. Unfortunately, the document uses ˜ (U+02DC SMALL TILDE) instead of ~ (U+007E TILDE), and I copy-pasted from it. [1]: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_02

* bit: Check __BYTE_ORDER__ for the native endianTavian Barnes2024-03-211-2/+2
| | | | __ORDER_NATIVE_ENDIAN__ is not a thing.
* bfstd: Check that wcwidth() is positiveTavian Barnes2024-03-201-2/+6
| | | | | wcwidth() returns -1 for non-printable characters, but terminals typically don't print anything for them, so treat them as 0.

* config: Don't mix [[attr]] and __attribute__((attr))Tavian Barnes2024-03-191-6/+2
| | | | | GCC and Clang don't support combining the two attribute syntaxes in arbitrary order. For now, just use the GNU style.

* xtime: Call tzset() from main() instead of lazilyTavian Barnes2024-03-076-66/+14
| | | | | | | | | | | | | 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

* ioq: Ensure ioq_ent is sufficiently alignedTavian Barnes2024-02-162-2/+9
| | | | | | | The natural alignment of struct ioq_ent is only 2 on m68k, so over-align it to at least 4 bytes on all platforms. Link: https://buildd.debian.org/status/fetch.php?pkg=bfs&arch=m68k&ver=3.1-1&stamp=1707699583

| | | | | | | | | | | 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'
