| | | | | | | | | | | | This is a partial MFC of rev 1.126 from HEAD's libkse. This only merges the fix which causes stderr_debug to write output to STDERR_FILENO instead of STDOUT_FILENO.

* MFC: Relevent commit logs are below.Daniel Eischen2006-03-1617-105/+134
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only catch SIGINFO (for dumping thread states) when LIBPTHREAD_DEBUG is defined in the environment. Modify the code path of the ifdef NOTYET part of _kse_single_thread(): o Don't reinitialise the atfork() handler list in the child. We are meant to call the child handler, and on subsequent fork()s should call all three functions as normal. o Don't reinitialise the thread specific keyed data in the child after a fork. Applications may require this for context. o Reinitialise curthread->tlflags after removing ourselves from (and reinitialising) the various internal thread lists. o Reinitialise __malloc_lock in the child after fork() (to balance our explicitly taking the lock prior to the fork()). With these changes, it is possible to enable the NOTYET code in thr_kern.c to allow the use of non-async-safe functions after fork()ing from a threaded program. Eliminate a race condition in timed waits (cv, mutex, and sleeps). Don't forget to initialize a tailq before using it. For the ``#ifdef NOTYET'' code that allows calling non-async-safe functions in the child after a fork() from a threaded process, use __sys_setprocmask() rather than setprocmask() to keep our signal handling sane. Without this fix, signals are essentially ignored in said child and things such as protection violations result in an endless busy loop. Allocate a thread's tcb last so it is easier to handle failures to malloc() siginfo. Include needed headers that were obtained through <pthread.h>. Sort headers while here. amd64 ----- Fix a race condition introduced when redzones were added. Use an atomic operation to return and adjust the stack (amd64). test ----- o Include <string.h> o Make this ILP32/LP64 clean: cast pointers to long.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | signals instead of having more intricate knowledge of thread state within signal handling. Simplify signal code because of above (by David Xu). Use macros for libpthread usage of pthread_cleanup_push() and pthread_cleanup_pop(). This removes some instances of malloc() and free() from the semaphore and pthread_once() implementations. When single threaded and forking(), make sure that the current thread's signal mask is inherited by the forked thread. Use private mutexes for libc and libpthread. Signals are deferred while threads hold private mutexes. This fix also breaks www/linuxpluginwrapper; a patch that fixes it is at http://people.freebsd.org/~deischen/kse/linuxpluginwrapper.diff Fix race condition in condition variables where handling a signal (pthread_kill() or kill()) may not see a wakeup (pthread_cond_signal() or pthread_cond_broadcast()).
