2268         compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
2269         is not defined.
2270
2271         * spinlock.c (__pthread_unlock): Call

2276
2277         * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning

2284 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
2285
2286         Timer nodes are now reference counted, and can be marked
2287         as deleted. This allows for the safe release of the global mutex
2288         in the middle without losing the timer being operated on.
2289
2290         * sysdeps/pthread/posix-timer.h (struct timer_node):  The inuse
2291         member is now an enum with three values, so that an intermediate
2292         state can be represented (deleted but not free for reuse yet).
2293         New refcount member added.
2294         * sysdeps/pthread/timer_routines.c: Likewise.
2295
2296         * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,

2298
2299         * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
2300         restructured, recursive deadlock bug fixed.
2301
2302         * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
2303         timer_addref to ensure that timer won't be deleted while mutex is not
2304         held. Also uses timer_invalid to perform validation of timer handle.
2305         * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
2306         * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
2307
2308 2000-06-14  Ulrich Drepper  <drepper@redhat.com>

2313 2000-06-13  Kaz Kylheku  <kaz@ashi.footprints.net>
2314
2315         A few optimizations.  Got rid of unnecessary wakeups of timer threads,
2316         tightened up some critical regions and micro-optimized some list
2317         manipulation code.
2318
2319         * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
2320         Returns int value now to indicate whether timer was queued at head.
2321         * sysdeps/pthread/posix-timer.h: Likewise.
2322         * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
2323         new return value from __timer_thread_queue_timer to avoid waking
2324         up timer thread unnecessarily.
2325
2326         * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
2327         inuse flag, because this requires mutex to be held.  Callers updated
2328         to do the check when they have the mutex.
2329         * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
2330
2331         * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
2332         regions: avoids making system calls while holding timer mutex, and
2333         a few computations were moved outside of the mutex as well.
2334         * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
2335
2336         * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
2337         to list_unlink_ip, meaning idempotent.  Pointer manipulation
2338         changed to get better better code out of gcc.
2339         * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
2340         version of list_unlink added here.
2341         * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
2342         function in all places: idempotent one for timers, non-idempotent
2343         one for thread nodes.
2344         * sysdeps/pthread/timer_settime: Likewise.
2345         * sysdeps/pthread/timer_routines.c: Likewise.
2346
2347 2000-06-13  Ulrich Drepper  <drepper@redhat.com>
2348
2349         * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.

2354 2000-06-12  Kazumoto Kojima  <kkojima@rr.iij4u.or.jp>

2362         * Makefile (tests): Add joinrace.
2363
2364         * Examples/ex6.c: Test return value of pthread_join.
2365
2366 2000-06-11  Geoff Keating  <geoffk@cygnus.com>
2367
2368         * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
2369         (__pthread_spin_trylock): Implement.
2370         (__pthread_spin_unlock): Implement.
2371         (__pthread_spin_init): Implement.
2372         (__pthread_spin_destroy): Implement.
2373
2374 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
2375
2376         * sysdeps/pthread/timer_routines.c (list_append): Little fix to
2377         really append the entry.

2382
2383 2000-06-10  Kaz Kylheku  <kaz@ashi.footprints.net>
2384
2385         * sysdeps/pthread/timer_create.c: Thread matching now done on
2386         clock type as well as thread attributes.
2387         There are individual global signal-delivering threads for
2388         different clock types.
2389         * sysdeps/pthread/posix-timer.h: Likewise.
2390         * sysdeps/pthread/timer_routines.c: Likewise.
2391
2392         * sysdeps/pthread/timer_routines.c: Thread allocation and
2393         deallocation function now remembers to put thread on active
2394         list and remove from active list.
2395         Thus now the feature of binding multiple timers
2396         to a single thread actually works.
2397
2398 2000-06-10  Ulrich Drepper  <drepper@redhat.com>
2399
2400         * pthread.c (__pthread_create_2_1): Optimize a bit.

2403         (nonexisting_handle): New function.  Same as old invalid_handle.
2404         * join.c (pthread_join): Use nonexisting_handle instead of
2405         invalid_handle to test for acceptable thread handle.
2406         * manager.c (pthread_handle_free): Likewise.
2407         * joinrace.c: New file.
2408         Reported by Permaine Cheung <pcheung@cygnus.com>.

2425         subtraction were switched.

2461
2462         * lockfile.c (__fresetlockfiles): Now also resets the list lock,
2463         not just the individual stream locks. Rewritten to use new

2466
2467         * lockfile.c (__flockfilelist, _funlockfilelist): New functions
2468         which lock and unlock the stream list using the new interface

2474         Child still calls __fresetlockfiles as before.
2475
2476         * linuxthreads.texi: Now explains what happens to streams at
2477         fork time. Also whole new section on forking and thread added.

2504 2000-05-12  Kaz Kylheku  <kaz@ashi.footprints.net>
2505
2506         Bugfix: The pthread_atfork mechanism now takes care of its
2507         own internal mutex at fork time.
2508
2509         * ptfork.c (__fork): Revised so that the mutex is held across
2510         the fork operation and while the handlers are called, and so that
2511         the child resets the mutex.
2512
2513         * linuxthreads.texi: Updated pthread_atfork documentation to make
2514         it clear that fork and pthread_atfork can't be reentered from
2515         atfork handlers, that pthread_atfork and fork are mutually atomic,
2516         and that the handlers are inherited by the child process.

3023         simultaneously.
3024         * restart.h: Restarts queue even on kernels that don't have
3025         queued real time signals (2.0, early 2.1), thanks to atomic counter,
3026         avoiding a rare race condition in pthread_cond_timedwait.
