        (DO_SET_THREAD_AREA): New macro, uses current syscall interface with
        existing %gs value as the segment to set.
        (INIT_THREAD_SELF): Rewritten using those.  Use set_thread_area only

        Bugfixes to the variant of the code for machines with no compare
        and swap.

        * spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Wait
        node was not being properly enqueued, due to failing to update
        the lock->__status field.

        * spinlock.c (__pthread_alt_timedlock): The oldstatus variable was
        being set inappropriately, causing the suspend function to be called
        with a null self pointer and crash.

        __compare_and_swap to compare_and_swap in code which assumes
        compare swap is available.

2000-07-18  Kaz Kylheku  <kaz@ashi.footprints.net>

        * spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Fixed

        set unless a null self pointer is passed to the functions.
        Eliminated redundant calls to thread_self().

        Timer nodes are now reference counted, and can be marked
        as deleted. This allows for the safe release of the global mutex
        in the middle without losing the timer being operated on.

        * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
        member is now an enum with three values, so that an intermediate
        state can be represented (deleted but not free for reuse yet).
        New refcount member added.
        * sysdeps/pthread/timer_routines.c: Likewise.

2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>

        A few optimizations.  Got rid of unnecessary wakeups of timer threads,
        tightened up some critical regions and micro-optimized some list
        manipulation code.

        * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
        Returns int value now to indicate whether timer was queued at head.
        * sysdeps/pthread/posix-timer.h: Likewise.
        * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
        new return value from __timer_thread_queue_timer to avoid waking
        up timer thread unnecessarily.

        * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
        inuse flag, because this requires mutex to be held.  Callers updated
        to do the check when they have the mutex.
        * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.

        * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
        regions: avoids making system calls while holding timer mutex, and
        a few computations were moved outside of the mutex as well.
        * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.

        * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
        to list_unlink_ip, meaning idempotent.  Pointer manipulation
        changed to get better better code out of gcc.
        * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
        version of list_unlink added here.
        * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
        function in all places: idempotent one for timers, non-idempotent
        one for thread nodes.
        * sysdeps/pthread/timer_settime: Likewise.
        * sysdeps/pthread/timer_routines.c: Likewise.

2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>

        * sysdeps/pthread/timer_create.c: Thread matching now done on
        clock type as well as thread attributes.
        There are individual global signal-delivering threads for
        different clock types.
        * sysdeps/pthread/posix-timer.h: Likewise.
        * sysdeps/pthread/timer_routines.c: Likewise.

        * sysdeps/pthread/timer_routines.c: Thread allocation and
        deallocation function now remembers to put thread on active
        list and remove from active list.
        Thus now the feature of binding multiple timers
        to a single thread actually works.

2000-06-04  Kaz Kylheku  <kaz@ashi.footprints.net>

        Added missing fork time handling of global libio lock.

        * lockfile.c (__fresetlockfiles): Now also resets the list lock,
        not just the individual stream locks. Rewritten to use new
        iterator interface provided by libio rather than accessing
        global variable.

        * lockfile.c (__flockfilelist, _funlockfilelist): New functions
        which lock and unlock the stream list using the new interface
        provied by libio.
        * internals.h: Likewise.

        * ptfork.c (__fork): Now calls __flockfilelist before fork,
        and __funlockfilelist in the parent after the fork.
        Child still calls __fresetlockfiles as before.

        * linuxthreads.texi: Now explains what happens to streams at
        fork time. Also whole new section on forking and thread added.
        Definition of pthread_atfork moved out of Miscellaneous Functions

2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>

        Bugfix: The pthread_atfork mechanism now takes care of its
        own internal mutex at fork time.

        * ptfork.c (__fork): Revised so that the mutex is held across
        the fork operation and while the handlers are called, and so that
        the child resets the mutex.

        * linuxthreads.texi: Updated pthread_atfork documentation to make
        it clear that fork and pthread_atfork can't be reentered from
        atfork handlers, that pthread_atfork and fork are mutually atomic,
        and that the handlers are inherited by the child process.

2000-05-24  Ulrich Drepper  <drepper@redhat.com>

        * Makefile (libpthread-routines): Add pspinlock.
        * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>

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

2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>

        * internals.h: New thread manager request type, REQ_KICK.
        * join.c (pthread_exit): main thread now calls exit() instead
        of _exit() in order to proper process cleanup.
        * manager.c (__pthread_manager): Do not terminate manager
        after unblocking main thread; wait for main thread's
        REQ_PROCESS_EXIT request instead.
        Also, added REQ_KICK case to handle new request; this just does
        nothing.
        * manager.c (pthread_exited): Do not terminate manager after
        unblocking main thread.
        * manager.c (__pthread_manager_sighandler): If the main thread
        is waiting for all other threads to die, send a REQ_KICK into
        the thread manager request pipe to get it to clean out the threads
        and unblock the main thread as soon as possible. This fixes
        the 2000 millisecond hang on shutdown bug.
        * Examples/ex7.c: New file, tests shutdown behavior when all threads
        including the main one call pthread_exit(), or implicitly do so.
        * Makefile (tests): Add ex7.

2000-05-05  Andreas Jaeger  <aj@suse.de>

        thread-local data handling.  Move p_self member in this area.
        * manager.c (pthread_handle_create): Adjust use of p_self.
        * sysdeps/i386/useldt.h (THREAD_SELF): Likewise.
        * pthread.c (__pthread_initial_thread): Adjust initialization.
        (__pthread_manager_thread): Likewise.

2000-04-29  Bruno Haible  <haible@clisp.cons.org>

        * join.c (pthread_exit): Use THREAD_GETMEM_NC instead of THREAD_GETMEM
        for eventmask larger than 1 word.

        (pthread_initialize): Remove this code here.
        * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h" again.  We
        are working around the problem in glibc.

2000-04-25  Ulrich Drepper  <drepper@redhat.com>

        * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
        now.  First gcc must be fixed (more concrete: libgcc).

        * pthread.c: Remove special treatement for interrupt handlers on x86.
        * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.

        headers.

2000-04-17  Ulrich Drepper  <drepper@redhat.com>

        * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
        (pthread_getcpuclockid): Don't compare thread_id with thread_self,
        use thread_handle().

2000-04-16  Ulrich Drepper  <drepper@redhat.com>

        * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
        if fast mutex is used.  Don't initialize `already_canceled' twice.
        Correctly test for return value of timedsuspend.

        * pthread.c: Correct long-time braino.  We never set SA_SIGINFO and
        therefore don't need the _rt versions of the signal handlers.

        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.

        new_thread_bottom.  Correct handling of stack size and when the

        minus one pagesize (not two).
