* Repo copy libpthreads to libkse.David E. O'Brien2007-10-09113-18511/+0
| | | | | | | | | This introduces the WITHOUT_LIBKSE nob, and changes WITHOUT_LIBPTHREADS to mean with neither threading libs. Approved by: re(kensmith) Notes: svn path=/head/; revision=172492
* Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it.Daniel Eischen2007-05-131-1/+1
| | | | | | | | | | | | | Warning, after symbol versioning is enabled, going back is not easy (use WITHOUT_SYMVER at your own risk). Change the default thread library to libthr. There most likely still needs to be a version bump for at least the thread libraries. If necessary, this will happen later. Notes: svn path=/head/; revision=169524

Specifically, a non-bound thread started as "suspended" (see pthread_attr_setcreatesuspend_np()) might not get scheduled at all when resumed, as the "active" flag would be set spuriously.

| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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()).
