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 12:05:08 -07:00			`#include "libc/mem/alloca.h"`

Improve backtraces We're now able to rewind the instruction pointer in x86 backtraces. This helps ensure addr2line cannot print information about unrelated adjacent code. I've restored -fno-schedule-insns2 in most cases because it really does cause unpredictable breakage for backtraces. 2024-05-30 15:11:45 -07:00			`const char DescribeBacktrace(char[160], const struct StackFrame ) libcesque;`
Add more fixes for new cosmocc toolchain We now have an `#include <cxxabi.h>` header which defines all the APIs Cosmopolitan's implemented so far. The `cosmocc` README.md file is now greatly expanded with documentation. 2023-11-11 22:32:12 -08:00			`#define DescribeBacktrace(x) DescribeBacktrace(alloca(160), x)`
