bsd: ensure mutex is initialized by bnoordhuis · Pull Request #3428 · libuv/libuv

bnoordhuis · 2022-01-17T08:37:42Z

The process title mutex was destroyed on library unload without ensuring
it was initialized - and it may not be because it's initialized lazily.

On most platforms it worked by accident because an "all zeroes" mutex is
synonymous with an initialized and unlocked mutex, but not on NetBSD.

Notable changes: - Build regression fixes for various platform updates (libuv/libuv#3428, libuv/libuv#3419, libuv/libuv#3423, libuv/libuv#3413, libuv/libuv#3431) - Support for GNU/Hurd (libuv/libuv#3450) - Release tool improvements (libuv/libuv-release-tool#13) - Better performing rw locks on Win32 (libuv/libuv#3383) - Support for posix_spawn API (libuv/libuv#3257) - Fixed regression on OpenBSD (libuv/libuv#3506) - Added uv_available_parallelism() (libuv/libuv#3499) - Other bug fixes (libuv/libuv#3524, libuv/libuv#3521) Fixes: nodejs#42290
