34 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
36 Added missing fork time handling of global libio lock.
38 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
39 not just the individual stream locks. Rewritten to use new
40 iterator interface provided by libio rather than accessing
43 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
44 which lock and unlock the stream list using the new interface
46 * internals.h: Likewise.
48 * ptfork.c (__fork): Now calls __flockfilelist before fork,

82 Bugfix: The pthread_atfork mechanism now takes care of its
83 own internal mutex at fork time.
85 * ptfork.c (__fork): Revised so that the mutex is held across
86 the fork operation and while the handlers are called, and so that
87 the child resets the mutex.
89 * linuxthreads.texi: Updated pthread_atfork documentation to make
90 it clear that fork and pthread_atfork can't be reentered from
91 atfork handlers, that pthread_atfork and fork are mutually atomic,
92 and that the handlers are inherited by the child process.
94 2000-05-24 Ulrich Drepper <drepper@redhat.com>
96 * Makefile (libpthread-routines): Add pspinlock.
97 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

136 object state is represented with additional bits which distinguish
137 whether that state was set up in the current process, or
138 in an ancestor process. If that state was set in an ancestor,
139 it means that a fork happened while thread was executing the init
140 function. In that case, the state is reset to NEVER.
141 * mutex.c (__pthread_once_fork_prepare): New function.
142 (__pthread_once_fork_child): Likewise

158 REQ_PROCESS_EXIT request instead.
159 Also, added REQ_KICK case to handle new request; this just does
161 * manager.c (pthread_exited): Do not terminate manager after
162 unblocking main thread.
163 * manager.c (__pthread_manager_sighandler): If the main thread
164 is waiting for all other threads to die, send a REQ_KICK into
165 the thread manager request pipe to get it to clean out the threads
166 and unblock the main thread as soon as possible. This fixes
167 the 2000 millisecond hang on shutdown bug.
168 * Examples/ex7.c: New file, tests shutdown behavior when all threads
169 including the main one call pthread_exit(), or implicitly do so.
170 * Makefile (tests): Add ex7.
172 2000-05-05 Andreas Jaeger <aj@suse.de>

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

554 2000-01-16 Ulrich Drepper <drepper@cygnus.com>

558 (pthread_rwlockattr_setkind_np): Allow
559 PTHREAD_RWLOCK_PREFER_WRITER_NONRECURSIVE_NP.
560 Patches by Kaz Kylheku <kaz@ashi.footprints.net>.
562 2000-01-12 Ulrich Drepper <drepper@cygnus.com>
564 * internals.h (pthread_readlock_info): New structure.
565 (_pthread_descr_struct): Add p_readlock_list, p_readlock_free, and
566 p_untracked_readlock_count.
567 * pthread.c (__pthread_initial_thread, pthread_manager_thread):
568 Add initializers for new fields.

588 Redesigned how cancellation unblocks a thread from internal
589 cancellation points (sem_wait, pthread_join,
590 pthread_cond_{wait,timedwait}).
591 Cancellation won't eat a signal in any of these functions
592 (*required* by POSIX and Single Unix Spec!).
593 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
594 simultaneous condition variable signal (not required by POSIX
595 or Single Unix Spec, but nice).
596 * spinlock.c: __pthread_lock queues back any received restarts
597 that don't belong to it instead of assuming ownership of lock
598 upon any restart; fastlock can no longer be acquired by two threads
600 * restart.h: Restarts queue even on kernels that don't have
601 queued real time signals (2.0, early 2.1), thanks to atomic counter,
602 avoiding a rare race condition in pthread_cond_timedwait.

647 new_thread_bottom. Correct handling of stack size and when the
648 rlimit method to guard for stack growth is used.
649 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
650 minus one pagesize (not two).
652 1999-12-03 Andreas Jaeger <aj@suse.de>
654 * Versions: Add __res_state with version GLIBC_2.2.

738 %gs from the signal context. For each signal handling function,
739 two wrappers are required, one for a non-RT signal and one for
