2980
2981         Timer nodes are now reference counted, and can be marked
2982         as deleted. This allows for the safe release of the global mutex
2983         in the middle without losing the timer being operated on.
2984
2985         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
2986         member is now an enum with three values, so that an intermediate

2995         restructured, recursive deadlock bug fixed.
2996
2997         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
2998         timer_addref to ensure that timer won't be deleted while mutex is not
2999         held. Also uses timer_invalid to perform validation of timer handle.
3000         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
3001         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.

3017         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
3018         new return value from __timer_thread_queue_timer to avoid waking
3019         up timer thread unnecessarily.
3020
3021         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
3022         inuse flag, because this requires mutex to be held.  Callers updated
3023         to do the check when they have the mutex.
3024         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
3025
3026         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
3027         regions: avoids making system calls while holding timer mutex, and
3028         a few computations were moved outside of the mutex as well.
3029         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
3030
3031         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
3032         to list_unlink_ip, meaning idempotent.  Pointer manipulation

3035         version of list_unlink added here.
3036         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
3037         function in all places: idempotent one for timers, non-idempotent
3038         one for thread nodes.
3039         * sysdeps/pthread/timer_settime: Likewise.
3040         * sysdeps/pthread/timer_routines.c: Likewise.

3079
3080         * sysdeps/pthread/timer_create.c: Thread matching now done on
3081         clock type as well as thread attributes.
3082         There are individual global signal-delivering threads for
3083         different clock types.
3084         * sysdeps/pthread/posix-timer.h: Likewise.
3085         * sysdeps/pthread/timer_routines.c: Likewise.
3086
3087         * sysdeps/pthread/timer_routines.c: Thread allocation and
3088         deallocation function now remembers to put thread on active
3089         list and remove from active list.
3090         Thus now the feature of binding multiple timers
3091         to a single thread actually works.
3092

3154
3155         Added missing fork time handling of global libio lock.
3156
3157         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
3158         not just the individual stream locks. Rewritten to use new
3159         iterator interface provided by libio rather than accessing
3160         global variable.
3161
3162         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
3163         which lock and unlock the stream list using the new interface
3164         provied by libio.

3166
3167         * ptfork.c (__fork): Now calls __flockfilelist before fork,
3168         and __funlockfilelist in the parent after the fork.
3169         Child still calls __fresetlockfiles as before.
3170
3171         * linuxthreads.texi: Now explains what happens to streams at
3172         fork time. Also whole new section on forking and thread added.
3173         Definition of pthread_atfork moved out of Miscellaneous Functions
3174         to this new section.

3199 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
3200
3201         Bugfix: The pthread_atfork mechanism now takes care of its
3202         own internal mutex at fork time.
3203
3204         * ptfork.c (__fork): Revised so that the mutex is held across
3205         the fork operation and while the handlers are called, and so that
3206         the child resets the mutex.
3207
3208         * linuxthreads.texi: Updated pthread_atfork documentation to make
3209         it clear that fork and pthread_atfork can't be reentered from
3210         atfork handlers, that pthread_atfork and fork are mutually atomic,
3211         and that the handlers are inherited by the child process.
3212

3251
3252 2000-05-06  Kaz Kylheku  <kaz@ashi.footprints.net>
3253
3254         * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
3255         object state is represented with additional bits which distinguish
3256         whether that state was set up in the current process, or
3257         in an ancestor process. If that state was set in an ancestor,
3258         it means that a fork happened while thread was executing the init
3259         function. In that case, the state is reset to NEVER.
3260         * mutex.c (__pthread_once_fork_prepare): New function.
3261         (__pthread_once_fork_child): Likewise

3271
3272         * internals.h: New thread manager request type, REQ_KICK.
3273         * join.c (pthread_exit): main thread now calls exit() instead
3274         of _exit() in order to proper process cleanup.
3275         * manager.c (__pthread_manager): Do not terminate manager
3276         after unblocking main thread; wait for main thread's
3277         REQ_PROCESS_EXIT request instead.
3278         Also, added REQ_KICK case to handle new request; this just does
3279         nothing.
3280         * manager.c (pthread_exited): Do not terminate manager after
3281         unblocking main thread.
3282         * manager.c (__pthread_manager_sighandler): If the main thread
3283         is waiting for all other threads to die, send a REQ_KICK into
3284         the thread manager request pipe to get it to clean out the threads
3285         and unblock the main thread as soon as possible. This fixes
3286         the 2000 millisecond hang on shutdown bug.
3287         * Examples/ex7.c: New file, tests shutdown behavior when all threads
3288         including the main one call pthread_exit(), or implicitly do so.
3289         * Makefile (tests): Add ex7.
3290
3291 2000-05-05  Andreas Jaeger  <aj@suse.de>

3321
3322         * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
