        * semaphore.h (SEM_FAILED): Use 0 not NULL.

2000-02-14  Ulrich Drepper  <drepper@redhat.com>

        * condvar.c (pthread_cond_timedwait_relative_old): Tight loop with
        nanosleep does not work either.  Get absolute time inside the
        loop.
        (pthread_cond_timedwait_relative_new): Likewise.
        Patch by Kaz Kylheku <kaz@ashi.footprints.net>.

2000-02-13  Ulrich Drepper  <drepper@redhat.com>

        * condvar.c (pthread_cond_timedwait_relative_old): Undo last patch
        but keep the code around.  A bug in the kernel prevent us from
        using the code.
        (pthread_cond_timedwait_relative_new): Likewise.
        (PR libc/1597 and libc/1598).

2000-02-01  Kaz Kylheku  <kaz@ashi.footprints.net>

        * condvar.c (pthread_cond_timedwait_relative_old): Do tight
        loop around nanosleep calls instead of around most of the function
        (pthread_cond_timedwait_relative_new): Likewise.
        body.  Got rid of backwards goto and one local.

2000-01-31  Ulrich Drepper  <drepper@redhat.com>

        * condvar.c (pthread_cond_timedwait_relative_old): Recompute time
        before every nanosleep call to account for time spent in the rest
        of the function.
        (pthread_cond_timedwait_relative_new): Likewise.
        Patch by khendricks@ivey.uwo.ca (PR libc/1564).

2000-01-29  Ulrich Drepper  <drepper@redhat.com>

        * condvar.c (pthread_cond_timedwait_relative_old): Get remaining time
        from nanosleep call so that in case we restart we only wait for the
        remaining time.
        (pthread_cond_timedwait_relative_new): Likewise.
        Patch by khendricks@ivey.uwo.ca (PR libc/1561).

2000-01-18  Ulrich Drepper  <drepper@cygnus.com>

        * manager.c (pthread_allocate_stack): Compute guard page address
        correctly.  Patch by HJ Lu.

2000-01-12  Ulrich Drepper  <drepper@cygnus.com>

        * internals.h (pthread_readlock_info): New structure.
        (_pthread_descr_struct): Add p_readlock_list, p_readlock_free, and
        p_untracked_readlock_count.
        * pthread.c (__pthread_initial_thread, pthread_manager_thread):
        Add initializers for new fields.
        * manager.c (pthread_free): Free read/write lock lists.
        * queue.h (queue_is_empty): New function.
        * rwlock.c: Implement requirements about when readers should get
        locks assigned.
        * sysdeps/pthread/pthread.h
        (PTHREAD_RWLOCK_PREFER_WRITER_NONRECURSIVE_NP): New definition.
        * sysdeps/pthread/bits/pthreadtypes.h (struct _pthread_rwlock_t):
        Define this name as well.
        Patches by Kaz Kylheku <kaz@ashi.footprints.net>.

2000-01-06  Andreas Jaeger  <aj@suse.de>

        * pthread.c: Remove extra initializer.

2000-01-05  Ulrich Drepper  <drepper@cygnus.com>

        * pthread.c (__pthread_initial_thread, pthread_manager_thread):
        Adjust initializers for struct _pthread_descr_struct change.
        * internals.h (struct _pthread_descr_struct): Move new elements to
        the end.

2000-01-03  Kaz Kylheku  <kaz@ashi.footprints.net>

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

1999-12-28  Ulrich Drepper  <drepper@cygnus.com>

        * sysdeps/alpha/pt-machine.h:  Move stack_pointer definition to the
        beginning.

        * manager.c (__pthread_start): Add one more cast to assignment of
        arg to prevent warning on 64bit machines.

1999-12-21  Ulrich Drepper  <drepper@cygnus.com>

        * manager.c (pthread_handle_create): Set p_pid of new thread
        before calling the callback function to report a new thread.

1999-12-20  Andreas Jaeger  <aj@suse.de>

        * pthread.c (pthread_initialize): Move getrlimit call after
        setting of errno.

1999-12-01  Ulrich Drepper  <drepper@cygnus.com>

        * sysdeps/i386/pt-machine.h: Move stack_pointer definition to the
        beginning.
        * sysdeps/i386/i686/pt-machine.h: Likewise.
        Patches by Alan Modra <alan@SPRI.Levels.UniSA.Edu.Au>.

        Use INIT_THREAD_SELF.
        * pthread.c (__pthread_manager_thread): Initialize p_lock.
        (__pthread_initialize_manager): Respect event flags also for creation
        of the manager thread.

1999-10-26  Ulrich Drepper  <drepper@cygnus.com>

        * restart.h (suspend_with_cancellation): Rewrite as a macro.

        * condvar.c (pthread_cond_timedwait_relative): Don't mark as inline.

1999-10-21  Xavier Leroy  <Xavier.Leroy@inria.fr>

        * linuxthreads/pthread.c: For i386, wrap pthread_handle_sigrestart
        and pthread_handle_sigcancel with functions that restore
        %gs from the signal context.  For each signal handling function,
        two wrappers are required, one for a non-RT signal and one for
        a RT signal.
        * linuxthreads/signal.c: For i386, add code to restore %gs
        from the signal context in pthread_sighandler and
        pthread_sighandler_rt.

1999-10-09  Andreas Jaeger  <aj@suse.de>

        manager.c; include semaphore.h for needed types.

1999-10-08  Ulrich Drepper  <drepper@cygnus.com>

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

1999-09-25  Ulrich Drepper  <drepper@cygnus.com>

        * condvar.c (pthread_cond_timedwait_relative): Never return with
        EINTR.  Patch by Andreas Schwab.

1999-09-19  Ulrich Drepper  <drepper@cygnus.com>

        * signals.c (sigaction): Correct last patch.  Don't select
        pthread_sighandler_rt based on the signal number but instead of
        the SA_SIGINFO flag.

1999-09-23  Ulrich Drepper  <drepper@cygnus.com>

        * specific.c: Move definitions of struct pthread_key_struct and

        * internals.h: Added p_nextlock entry to separate queueing for a

        and not the new value.

1999-05-16  Xavier Leroy  <Xavier.Leroy@inria.fr>

        * manager.c: If pthread_create() is given a NULL attribute
        and the thread manager runs with a realtime policy, set the
        scheduling policy of the newly created thread back to SCHED_OTHER.
        * manager.c: If the PTHREAD_INHERIT_SCHED attribute is given,
        initialize the schedpolicy field of new_thread->p_start_args
        to that of the calling thread.
