101 Added missing fork time handling of global libio lock.
103 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
104 not just the individual stream locks. Rewritten to use new
105 iterator interface provided by libio rather than accessing
108 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
109 which lock and unlock the stream list using the new interface
111 * internals.h: Likewise.

143 * Examples/ex8.c: New file.

147 Bugfix: The pthread_atfork mechanism now takes care of its
148 own internal mutex at fork time.
150 * ptfork.c (__fork): Revised so that the mutex is held across
151 the fork operation and while the handlers are called, and so that
152 the child resets the mutex.
154 * linuxthreads.texi: Updated pthread_atfork documentation to make
155 it clear that fork and pthread_atfork can't be reentered from
156 atfork handlers, that pthread_atfork and fork are mutually atomic,
157 and that the handlers are inherited by the child process.
159 2000-05-24 Ulrich Drepper <drepper@redhat.com>
161 * Makefile (libpthread-routines): Add pspinlock.
162 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

201 object state is represented with additional bits which distinguish
202 whether that state was set up in the current process, or
203 in an ancestor process. If that state was set in an ancestor,
204 it means that a fork happened while thread was executing the init
205 function. In that case, the state is reset to NEVER.
206 * mutex.c (__pthread_once_fork_prepare): New function.
207 (__pthread_once_fork_child): Likewise

223 REQ_PROCESS_EXIT request instead.
224 Also, added REQ_KICK case to handle new request; this just does
226 * manager.c (pthread_exited): Do not terminate manager after
227 unblocking main thread.
228 * manager.c (__pthread_manager_sighandler): If the main thread
229 is waiting for all other threads to die, send a REQ_KICK into
230 the thread manager request pipe to get it to clean out the threads
231 and unblock the main thread as soon as possible. This fixes
232 the 2000 millisecond hang on shutdown bug.
233 * Examples/ex7.c: New file, tests shutdown behavior when all threads
234 including the main one call pthread_exit(), or implicitly do so.

317 if fast mutex is used. Don't initialize `already_canceled' twice.

653 Redesigned how cancellation unblocks a thread from internal
654 cancellation points (sem_wait, pthread_join,
655 pthread_cond_{wait,timedwait}).
656 Cancellation won't eat a signal in any of these functions
657 (*required* by POSIX and Single Unix Spec!).
658 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
659 simultaneous condition variable signal (not required by POSIX
660 or Single Unix Spec, but nice).
661 * spinlock.c: __pthread_lock queues back any received restarts
662 that don't belong to it instead of assuming ownership of lock
663 upon any restart; fastlock can no longer be acquired by two threads
665 * restart.h: Restarts queue even on kernels that don't have
666 queued real time signals (2.0, early 2.1), thanks to atomic counter,
667 avoiding a rare race condition in pthread_cond_timedwait.

712 new_thread_bottom. Correct handling of stack size and when the
713 rlimit method to guard for stack growth is used.
714 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
715 minus one pagesize (not two).
717 1999-12-03 Andreas Jaeger <aj@suse.de>
719 * Versions: Add __res_state with version GLIBC_2.2.

838 * manager.c (__pthread_manager) [REQ_POST]: Use __new_sem_post
839 directly instead of calling sem_post which should not be necessary
840 but is faster and might help in some case to work around problems.
