This PR moves that code into `sys::pal`, which now exposes a non-movable wrapper type for `pthread_mutex_t` and `pthread_condvar_t`. 2024-10-01T20:05:35+00:00 joboet jonasboettiger@icloud.com 2024-10-01T12:57:38+00:00 urn:sha1:c1acccdf1744561d4dda9b943fa91d873cea3b40 This PR replaces the `LazyBox` wrapper used to allocate the pthread primitives with `OnceBox`, which has a more familiar API mirroring that of `OnceLock`. This cleans up the code in preparation for larger changes like #128184 (from which this PR was split) and allows some neat optimizations, like avoid an acquire-load of the allocation pointer in `Mutex::unlock`, where the initialization of the allocation must have already been observed. Additionally, I've gotten rid of the TEEOS `Condvar` code, it's just a duplicate of the pthread one anyway and I didn't want to repeat myself. 2024-09-22T23:11:29+00:00 Michael Goulet michael@errs.io 2024-09-22T23:05:04+00:00 urn:sha1:c682aa162b0d41e21cc6748f4fecfe01efb69d1f 2024-03-12T14:41:06+00:00 joboet jonasboettiger@icloud.com 2024-03-12T13:55:06+00:00 urn:sha1:22a5267c83a3e17f2b763279eb24bb632c45dc6b
