78 Added missing fork time handling of global libio lock.
80 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
81 not just the individual stream locks. Rewritten to use new
82 iterator interface provided by libio rather than accessing
85 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
86 which lock and unlock the stream list using the new interface
88 * internals.h: Likewise.

120 * Examples/ex8.c: New file.
122 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
124 Bugfix: The pthread_atfork mechanism now takes care of its
125 own internal mutex at fork time.
127 * ptfork.c (__fork): Revised so that the mutex is held across
128 the fork operation and while the handlers are called, and so that
129 the child resets the mutex.
131 * linuxthreads.texi: Updated pthread_atfork documentation to make
132 it clear that fork and pthread_atfork can't be reentered from
133 atfork handlers, that pthread_atfork and fork are mutually atomic,
134 and that the handlers are inherited by the child process.
136 2000-05-24 Ulrich Drepper <drepper@redhat.com>
138 * Makefile (libpthread-routines): Add pspinlock.
139 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

178 object state is represented with additional bits which distinguish
179 whether that state was set up in the current process, or
180 in an ancestor process. If that state was set in an ancestor,
181 it means that a fork happened while thread was executing the init
182 function. In that case, the state is reset to NEVER.
183 * mutex.c (__pthread_once_fork_prepare): New function.
184 (__pthread_once_fork_child): Likewise

199 after unblocking main thread; wait for main thread's
200 REQ_PROCESS_EXIT request instead.
201 Also, added REQ_KICK case to handle new request; this just does
203 * manager.c (pthread_exited): Do not terminate manager after
204 unblocking main thread.
205 * manager.c (__pthread_manager_sighandler): If the main thread
206 is waiting for all other threads to die, send a REQ_KICK into
207 the thread manager request pipe to get it to clean out the threads
208 and unblock the main thread as soon as possible. This fixes
209 the 2000 millisecond hang on shutdown bug.
210 * Examples/ex7.c: New file, tests shutdown behavior when all threads
211 including the main one call pthread_exit(), or implicitly do so.
212 * Makefile (tests): Add ex7.

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

630 Redesigned how cancellation unblocks a thread from internal
631 cancellation points (sem_wait, pthread_join,
632 pthread_cond_{wait,timedwait}).
633 Cancellation won't eat a signal in any of these functions
634 (*required* by POSIX and Single Unix Spec!).
635 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
636 simultaneous condition variable signal (not required by POSIX
637 or Single Unix Spec, but nice).
638 * spinlock.c: __pthread_lock queues back any received restarts
639 that don't belong to it instead of assuming ownership of lock
640 upon any restart; fastlock can no longer be acquired by two threads
642 * restart.h: Restarts queue even on kernels that don't have
643 queued real time signals (2.0, early 2.1), thanks to atomic counter,
644 avoiding a rare race condition in pthread_cond_timedwait.

689 new_thread_bottom. Correct handling of stack size and when the
690 rlimit method to guard for stack growth is used.
691 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
692 minus one pagesize (not two).
694 1999-12-03 Andreas Jaeger <aj@suse.de>
