Justine Tunney	dd04aeba1c	Increase stack size to 128k and guard size to 16k ... This improves our compatibility with Apple M1.	2022-12-18 22:58:29 -08:00
Justine Tunney	e522aa3a07	Make more threading improvements ... - ASAN memory morgue is now lockless - Make C11 atomics header more portable - Rewrote pthread keys support to be lockless - Simplify Python's unicode table unpacking code - Make crash report write(2) closer to being atomic - Make it possible to strace/ftrace a single thread - ASAN now checks nul-terminated strings fast and properly - Windows fork() now restores TLS memory of calling thread	2022-11-01 23:28:26 -07:00
Justine Tunney	60cb435cb4	Implement pthread_atfork() ... If threads are being used, then fork() will now acquire and release and runtime locks so that fork() may be safely used from threads. This also makes vfork() thread safe, because pthread mutexes will do nothing when the process is a child of vfork(). More torture tests have been written to confirm this all works like a charm. Additionally: - Invent hexpcpy() api - Rename nsync_malloc_() to kmalloc() - Complete posix named semaphore implementation - Make pthread_create() asynchronous signal safe - Add rm, rmdir, and touch to command interpreter builtins - Invent sigisprecious() and modify sigset functions to use it - Add unit tests for posix_spawn() attributes and fix its bugs One unresolved problem is the reclaiming of *NSYNC waiter memory in the forked child processes, within apps which have threads waiting on locks	2022-10-16 12:25:13 -07:00
