Bugfix to pthread_key_delete. It was iterating over the thread
manager's linked list of threads, behind the thread manager's

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).

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.
2000-06-13 Ulrich Drepper <drepper@redhat.com>

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.
2000-06-10 Ulrich Drepper <drepper@redhat.com>
* pthread.c (__pthread_create_2_1): Optimize a bit.
* internals.h (invalid_handle): Also test for p_terminated != 0.

not just the individual stream locks. Rewritten to use new

global variable.

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.

fork time. Also whole new section on forking and thread added.
Definition of pthread_atfork moved out of Miscellaneous Functions
to this new section.

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.

* 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.

* 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.

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).
2000-04-24 Ulrich Drepper <drepper@redhat.com>
* pthread.c: Remove special treatement for interrupt handlers on x86.
* manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.

if fast mutex is used. Don't initialize `already_canceled' twice.
Correctly test for return value of timedsuspend.

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.
