1960         and forth between the processors (explanation by Asis K. Mallick

2356         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
2357         tightened up some critical regions and micro-optimized some list
2358         manipulation code.
2360         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
2361         Returns int value now to indicate whether timer was queued at head.
2362         * sysdeps/pthread/posix-timer.h: Likewise.
2363         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
2364         new return value from __timer_thread_queue_timer to avoid waking
2365         up timer thread unnecessarily.
2367         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
2368         inuse flag, because this requires mutex to be held.  Callers updated
2369         to do the check when they have the mutex.
2370         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
2372         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
2373         regions: avoids making system calls while holding timer mutex, and
2374         a few computations were moved outside of the mutex as well.
2375         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
2377         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
2378         to list_unlink_ip, meaning idempotent.  Pointer manipulation
2379         changed to get better better code out of gcc.
2380         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
2381         version of list_unlink added here.
2382         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
2383         function in all places: idempotent one for timers, non-idempotent
2384         one for thread nodes.
2385         * sysdeps/pthread/timer_settime: Likewise.
2386         * sysdeps/pthread/timer_routines.c: Likewise.
2388 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
2390         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.
2391         * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.
2393         * sysdeps/pthread/Makefile: Remove tests definition.

2401 2000-06-12  Ulrich Drepper  <drepper@redhat.com>
2403         * Makefile (tests): Add joinrace.
2405         * Examples/ex6.c: Test return value of pthread_join.
2407 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
2409         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
2410         (__pthread_spin_trylock): Implement.
2411         (__pthread_spin_unlock): Implement.
2412         (__pthread_spin_init): Implement.
2413         (__pthread_spin_destroy): Implement.
2415 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
2417         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
2418         really append the entry.
2420 2000-06-10  Andreas Jaeger  <aj@suse.de>
2422         * lockfile.c (__fresetlockfiles): Remove unused variable fp.
2424 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
2426         * sysdeps/pthread/timer_create.c: Thread matching now done on
2427         clock type as well as thread attributes.
2428         There are individual global signal-delivering threads for
2429         different clock types.
2430         * sysdeps/pthread/posix-timer.h: Likewise.
2431         * sysdeps/pthread/timer_routines.c: Likewise.
2433         * sysdeps/pthread/timer_routines.c: Thread allocation and
2434         deallocation function now remembers to put thread on active
2435         list and remove from active list.
2436         Thus now the feature of binding multiple timers
2437         to a single thread actually works.
2439 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
2441         * pthread.c (__pthread_create_2_1): Optimize a bit.
2443         * internals.h (invalid_handle): Also test for p_terminated != 0.

2447         * manager.c (pthread_handle_free): Likewise.
2448         * joinrace.c: New file.
2449         Reported by Permaine Cheung <pcheung@cygnus.com>.

2456         * sysdeps/pthread/tst-timer.c (main): Rewrite initializers to
2457         avoid warnings.
2459         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):

2463         CPUTIME clock ID.  Add support for thread clocks.
2465         * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
2466         subtraction were switched.
2468         * sysdeps/pthread/timer_routines.c (init_module): Use
2469         THREAD_MAXNODES threads.

2501         Added missing fork time handling of global libio lock.
2503         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
2504         not just the individual stream locks. Rewritten to use new
2505         iterator interface provided by libio rather than accessing
2506         global variable.
2508         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
2509         which lock and unlock the stream list using the new interface
2510         provied by libio.
2511         * internals.h: Likewise.
2513         * ptfork.c (__fork): Now calls __flockfilelist before fork,

2548         own internal mutex at fork time.
2550         * ptfork.c (__fork): Revised so that the mutex is held across
2551         the fork operation and while the handlers are called, and so that
2552         the child resets the mutex.
2554         * linuxthreads.texi: Updated pthread_atfork documentation to make
2555         it clear that fork and pthread_atfork can't be reentered from
2556         atfork handlers, that pthread_atfork and fork are mutually atomic,
2557         and that the handlers are inherited by the child process.

2601         object state is represented with additional bits which distinguish
2602         whether that state was set up in the current process, or
2603         in an ancestor process. If that state was set in an ancestor,
2604         it means that a fork happened while thread was executing the init
2605         function. In that case, the state is reset to NEVER.
2606         * mutex.c (__pthread_once_fork_prepare): New function.

2618         * internals.h: New thread manager request type, REQ_KICK.
2619         * join.c (pthread_exit): main thread now calls exit() instead
2620         of _exit() in order to proper process cleanup.
2621         * manager.c (__pthread_manager): Do not terminate manager
2622         after unblocking main thread; wait for main thread's
2623         REQ_PROCESS_EXIT request instead.
2624         Also, added REQ_KICK case to handle new request; this just does
2625         nothing.
2626         * manager.c (pthread_exited): Do not terminate manager after
2627         unblocking main thread.
2628         * manager.c (__pthread_manager_sighandler): If the main thread
2629         is waiting for all other threads to die, send a REQ_KICK into
2630         the thread manager request pipe to get it to clean out the threads
2631         and unblock the main thread as soon as possible. This fixes
2632         the 2000 millisecond hang on shutdown bug.
2633         * Examples/ex7.c: New file, tests shutdown behavior when all threads
2634         including the main one call pthread_exit(), or implicitly do so.
2635         * Makefile (tests): Add ex7.
2637 2000-05-05  Andreas Jaeger  <aj@suse.de>
2639         * sysdeps/unix/sysv/linux/i386/getcpuclockid.c

2684 2000-04-20  Jakub Jelinek  <jakub@redhat.com>
2686         * sysdeps/pthread/bits/libc-lock.h: Only declare __pthread_rwlock_*
2687         if __USE_UNIX98.
2689 2000-04-18  Andreas Jaeger  <aj@suse.de>

2714 2000-04-16  Ulrich Drepper  <drepper@redhat.com>
2716         * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
2717         if fast mutex is used.  Don't initialize `already_canceled' twice.
2718         Correctly test for return value of timedsuspend.
2720         * pthread.c: Correct long-time braino.  We never set SA_SIGINFO and
2721         therefore don't need the _rt versions of the signal handlers.

4327         Since sigset_t no longer fits in a register, we can't pass in the
4328         thread's initial mask so easily.  Take this opportunity to simplify
4329         the clone implementation by only accepting a single void* argument.
4331         * manager.c (__pthread_manager): Put thread vitals in the thread
4332         struct instead of as arguments through clone.
4333         (pthread_start_thread): Look for them there.
4334         * internals.h (struct _pthread): Add p_initial_fn,
4335         p_initial_fn_arg, p_initial_mask.  Fix __pthread_manager proto.
4336         * pthread.c (pthread_initialize_manager): Revise clone invocation.
