2962
2963         Timer nodes are now reference counted, and can be marked
2964         as deleted. This allows for the safe release of the global mutex
2965         in the middle without losing the timer being operated on.
2966
2967         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
2968         member is now an enum with three values, so that an intermediate
2969         state can be represented (deleted but not free for reuse yet).
2970         New refcount member added.
2971         * sysdeps/pthread/timer_routines.c: Likewise.

2977         restructured, recursive deadlock bug fixed.
2978
2979         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
2980         timer_addref to ensure that timer won't be deleted while mutex is not
2981         held. Also uses timer_invalid to perform validation of timer handle.
2982         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
2983         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.

2999         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
3000         new return value from __timer_thread_queue_timer to avoid waking
3001         up timer thread unnecessarily.
3002
3003         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
3004         inuse flag, because this requires mutex to be held.  Callers updated
3005         to do the check when they have the mutex.
3006         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
3007
3008         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
3009         regions: avoids making system calls while holding timer mutex, and
3010         a few computations were moved outside of the mutex as well.
3011         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
3012
3013         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
3014         to list_unlink_ip, meaning idempotent.  Pointer manipulation

3016         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
3017         version of list_unlink added here.
3018         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
3019         function in all places: idempotent one for timers, non-idempotent
3020         one for thread nodes.
3021         * sysdeps/pthread/timer_settime: Likewise.
3022         * sysdeps/pthread/timer_routines.c: Likewise.
3023
3024 2000-06-13  Ulrich Drepper  <drepper@redhat.com>

3061
3062         * sysdeps/pthread/timer_create.c: Thread matching now done on
3063         clock type as well as thread attributes.
3064         There are individual global signal-delivering threads for
3065         different clock types.
3066         * sysdeps/pthread/posix-timer.h: Likewise.
3067         * sysdeps/pthread/timer_routines.c: Likewise.
3068
3069         * sysdeps/pthread/timer_routines.c: Thread allocation and
3070         deallocation function now remembers to put thread on active
3071         list and remove from active list.
3072         Thus now the feature of binding multiple timers
3073         to a single thread actually works.
3074

3148

3151         Child still calls __fresetlockfiles as before.
3152
3153         * linuxthreads.texi: Now explains what happens to streams at
3154         fork time. Also whole new section on forking and thread added.
3155         Definition of pthread_atfork moved out of Miscellaneous Functions

3182
3183         Bugfix: The pthread_atfork mechanism now takes care of its
3184         own internal mutex at fork time.
3185
3186         * ptfork.c (__fork): Revised so that the mutex is held across
3187         the fork operation and while the handlers are called, and so that
3188         the child resets the mutex.
3189
3190         * linuxthreads.texi: Updated pthread_atfork documentation to make
3191         it clear that fork and pthread_atfork can't be reentered from

3193         and that the handlers are inherited by the child process.
3194

3234 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>

3236         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
3237         object state is represented with additional bits which distinguish
3238         whether that state was set up in the current process, or
3239         in an ancestor process. If that state was set in an ancestor,
3240         it means that a fork happened while thread was executing the init
3241         function. In that case, the state is reset to NEVER.
3242         * mutex.c (__pthread_once_fork_prepare): New function.

3255         * join.c (pthread_exit): main thread now calls exit() instead
3256         of _exit() in order to proper process cleanup.
3257         * manager.c (__pthread_manager): Do not terminate manager
3258         after unblocking main thread; wait for main thread's
3259         REQ_PROCESS_EXIT request instead.
3260         Also, added REQ_KICK case to handle new request; this just does
3261         nothing.
3262         * manager.c (pthread_exited): Do not terminate manager after
3263         unblocking main thread.
3264         * manager.c (__pthread_manager_sighandler): If the main thread
3265         is waiting for all other threads to die, send a REQ_KICK into
3266         the thread manager request pipe to get it to clean out the threads
3267         and unblock the main thread as soon as possible. This fixes
3268         the 2000 millisecond hang on shutdown bug.
3269         * Examples/ex7.c: New file, tests shutdown behavior when all threads
3270         including the main one call pthread_exit(), or implicitly do so.
3271         * Makefile (tests): Add ex7.
3272
3273 2000-05-05  Andreas Jaeger  <aj@suse.de>

3303
3304         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
