4568         Timer nodes are now reference counted, and can be marked
4569         as deleted. This allows for the safe release of the global mutex
4570         in the middle without losing the timer being operated on.
4572         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
4573         member is now an enum with three values, so that an intermediate
4574         state can be represented (deleted but not free for reuse yet).
4575         New refcount member added.
4576         * sysdeps/pthread/timer_routines.c: Likewise.
4578         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,

4597         A few optimizations.  Got rid of unnecessary wakeups of timer threads,

4606         up timer thread unnecessarily.
4608         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4609         inuse flag, because this requires mutex to be held.  Callers updated
4610         to do the check when they have the mutex.
4611         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4613         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4614         regions: avoids making system calls while holding timer mutex, and
4615         a few computations were moved outside of the mutex as well.
4616         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4618         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed

4621         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4622         version of list_unlink added here.
4623         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4624         function in all places: idempotent one for timers, non-idempotent
4625         one for thread nodes.
4626         * sysdeps/pthread/timer_settime: Likewise.
4627         * sysdeps/pthread/timer_routines.c: Likewise.

4668         clock type as well as thread attributes.
4669         There are individual global signal-delivering threads for
4670         different clock types.
4671         * sysdeps/pthread/posix-timer.h: Likewise.
4672         * sysdeps/pthread/timer_routines.c: Likewise.
4674         * sysdeps/pthread/timer_routines.c: Thread allocation and
4675         deallocation function now remembers to put thread on active
4676         list and remove from active list.
4677         Thus now the feature of binding multiple timers
4678         to a single thread actually works.

4747         global variable.
4749         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4750         which lock and unlock the stream list using the new interface
4751         provied by libio.

4789         own internal mutex at fork time.
4791         * ptfork.c (__fork): Revised so that the mutex is held across
4792         the fork operation and while the handlers are called, and so that

4795         * linuxthreads.texi: Updated pthread_atfork documentation to make
4796         it clear that fork and pthread_atfork can't be reentered from

4859         * internals.h: New thread manager request type, REQ_KICK.
4860         * join.c (pthread_exit): main thread now calls exit() instead

4862         * manager.c (__pthread_manager): Do not terminate manager
4863         after unblocking main thread; wait for main thread's
4864         REQ_PROCESS_EXIT request instead.
4865         Also, added REQ_KICK case to handle new request; this just does
4866         nothing.
4867         * manager.c (pthread_exited): Do not terminate manager after
4868         unblocking main thread.
4869         * manager.c (__pthread_manager_sighandler): If the main thread
4870         is waiting for all other threads to die, send a REQ_KICK into
4871         the thread manager request pipe to get it to clean out the threads
4872         and unblock the main thread as soon as possible. This fixes
4873         the 2000 millisecond hang on shutdown bug.
4874         * Examples/ex7.c: New file, tests shutdown behavior when all threads

4909         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for

4914         * pthread.c: Remove special treatement for interrupt handlers on x86.

4917         necessary.

5295         cancellation points (sem_wait, pthread_join,
5296         pthread_cond_{wait,timedwait}).
5297         Cancellation won't eat a signal in any of these functions
5298         (*required* by POSIX and Single Unix Spec!).
5299         * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a

5305         simultaneously.
5306         * restart.h: Restarts queue even on kernels that don't have
5307         queued real time signals (2.0, early 2.1), thanks to atomic counter,
5308         avoiding a rare race condition in pthread_cond_timedwait.

5355         * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
5356         minus one pagesize (not two).
