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

	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>

	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.

	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.

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

	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>

	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

	including the main one call pthread_exit(), or implicitly do so.

	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.
