2112 Patch by Kaz Kylheku <kaz@ashi.footprints.net>.
2114 2000-06-19 H.J. Lu <hjl@gnu.org>
2116 * spinlock.h (HAS_COMPARE_AND_SWAP): Defined if
2117 HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS is defined.
2118 (compare_and_swap_with_release_semantics): New. Default to
2119 compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
2122 * spinlock.c (__pthread_unlock): Call
2123 compare_and_swap_with_release_semantics () instead of
2124 compare_and_swap ().
2126 2000-06-19 Ulrich Drepper <drepper@redhat.com>
2128 * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning

2135 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
2137 Timer nodes are now reference counted, and can be marked
2138 as deleted. This allows for the safe release of the global mutex
2139 in the middle without losing the timer being operated on.
2141 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
2142 member is now an enum with three values, so that an intermediate
2143 state can be represented (deleted but not free for reuse yet).
2144 New refcount member added.
2145 * sysdeps/pthread/timer_routines.c: Likewise.
2147 * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,
2148 timer_valid): New inline functions added.
2150 * sysdeps/pthread/timer_gettime.c (timer_gettime): Function
2151 restructured, recursive deadlock bug fixed.
2153 * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
2154 timer_addref to ensure that timer won't be deleted while mutex is not
2155 held. Also uses timer_invalid to perform validation of timer handle.
2156 * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
2157 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
2159 2000-06-14 Ulrich Drepper <drepper@redhat.com>

2162 Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
2164 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
2166 A few optimizations. Got rid of unnecessary wakeups of timer threads,
2167 tightened up some critical regions and micro-optimized some list
2170 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
2171 Returns int value now to indicate whether timer was queued at head.
2172 * sysdeps/pthread/posix-timer.h: Likewise.
2173 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
2174 new return value from __timer_thread_queue_timer to avoid waking
2175 up timer thread unnecessarily.
2177 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
2178 inuse flag, because this requires mutex to be held. Callers updated
2179 to do the check when they have the mutex.
2180 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
2182 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
2183 regions: avoids making system calls while holding timer mutex, and
2184 a few computations were moved outside of the mutex as well.
2185 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
2187 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
2188 to list_unlink_ip, meaning idempotent. Pointer manipulation
2189 changed to get better better code out of gcc.
2190 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
2191 version of list_unlink added here.
2192 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
2193 function in all places: idempotent one for timers, non-idempotent
2194 one for thread nodes.
2195 * sysdeps/pthread/timer_settime: Likewise.
2196 * sysdeps/pthread/timer_routines.c: Likewise.
2198 2000-06-13 Ulrich Drepper <drepper@redhat.com>
2200 * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.
2201 * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.
2203 * sysdeps/pthread/Makefile: Remove tests definition.

2213 * Makefile (tests): Add joinrace.
2215 * Examples/ex6.c: Test return value of pthread_join.
2217 2000-06-11 Geoff Keating <geoffk@cygnus.com>
2219 * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
2220 (__pthread_spin_trylock): Implement.
2221 (__pthread_spin_unlock): Implement.
2222 (__pthread_spin_init): Implement.
2223 (__pthread_spin_destroy): Implement.
2225 2000-06-10 Ulrich Drepper <drepper@redhat.com>
2227 * sysdeps/pthread/timer_routines.c (list_append): Little fix to
2228 really append the entry.
2230 2000-06-10 Andreas Jaeger <aj@suse.de>
2232 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
2234 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
2236 * sysdeps/pthread/timer_create.c: Thread matching now done on
2237 clock type as well as thread attributes.
2238 There are individual global signal-delivering threads for
2239 different clock types.
2240 * sysdeps/pthread/posix-timer.h: Likewise.
2241 * sysdeps/pthread/timer_routines.c: Likewise.
2243 * sysdeps/pthread/timer_routines.c: Thread allocation and
2244 deallocation function now remembers to put thread on active
2245 list and remove from active list.
2246 Thus now the feature of binding multiple timers
2247 to a single thread actually works.
2249 2000-06-10 Ulrich Drepper <drepper@redhat.com>
2251 * pthread.c (__pthread_create_2_1): Optimize a bit.
2253 * internals.h (invalid_handle): Also test for p_terminated != 0.
2254 (nonexisting_handle): New function. Same as old invalid_handle.
2255 * join.c (pthread_join): Use nonexisting_handle instead of
2256 invalid_handle to test for acceptable thread handle.
2257 * manager.c (pthread_handle_free): Likewise.
2258 * joinrace.c: New file.
2259 Reported by Permaine Cheung <pcheung@cygnus.com>.
2261 2000-06-08 Ulrich Drepper <drepper@redhat.com>
2263 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
2264 Correct handling of matching variable.
2266 * sysdeps/pthread/tst-timer.c (main): Rewrite initializers to
2269 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
2270 Be prepared for empty timer list.
2272 * sysdeps/pthread/timer_create.c (timer_create): Correct names of
2273 CPUTIME clock ID. Add support for thread clocks.
2275 * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
2276 subtraction were switched.
2278 * sysdeps/pthread/timer_routines.c (init_module): Use
2279 THREAD_MAXNODES threads.

2282 * sysdeps/pthread/timer_create.c: Fill in creator_pid.
2283 * sysdeps/pthread/timer_routines.c (thread_expire_timer): Send signal
2284 with sigqueueinfo is this system call is available.
2286 * sysdeps/pthread/timer_create.c (timer_create): Allow
2287 CLOCK_CPUTIME if _POSIX_CPUTIME is defined.
2289 * sysdeps/pthread/Makefile: New file. Add rules to build timer
2291 * sysdeps/unix/sysv/linux/bits/local_lim.h: Add TIMER_MAX.

2304 2000-06-08 Ulrich Drepper <drepper@redhat.com>
2306 * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and
2307 LINK_MAX definitions if necessary.
2309 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
2311 Added missing fork time handling of global libio lock.
2313 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
2314 not just the individual stream locks. Rewritten to use new
2315 iterator interface provided by libio rather than accessing
2318 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
2319 which lock and unlock the stream list using the new interface
2321 * internals.h: Likewise.
2323 * ptfork.c (__fork): Now calls __flockfilelist before fork,
2324 and __funlockfilelist in the parent after the fork.
2325 Child still calls __fresetlockfiles as before.
2327 * linuxthreads.texi: Now explains what happens to streams at
2328 fork time. Also whole new section on forking and thread added.
2329 Definition of pthread_atfork moved out of Miscellaneous Functions
2330 to this new section.
2332 2000-06-04 Jakub Jelinek <jakub@redhat.com>
2334 * sysdeps/sparc/sparc32/sparcv9/pspinlock.c (__pthread_spin_lock):

2353 * Examples/ex8.c: New file.
2355 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
2357 Bugfix: The pthread_atfork mechanism now takes care of its
2358 own internal mutex at fork time.
2360 * ptfork.c (__fork): Revised so that the mutex is held across
2361 the fork operation and while the handlers are called, and so that
2362 the child resets the mutex.
2364 * linuxthreads.texi: Updated pthread_atfork documentation to make
2365 it clear that fork and pthread_atfork can't be reentered from
2366 atfork handlers, that pthread_atfork and fork are mutually atomic,
2367 and that the handlers are inherited by the child process.
2369 2000-05-24 Ulrich Drepper <drepper@redhat.com>
2371 * Makefile (libpthread-routines): Add pspinlock.
2372 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.
2373 Use struct _pthread_fastlock instead of pthread_spinlock_t.
2374 * condvar.c: Likewise.
2375 * internals.h: Likewise.
2377 * manager.c: Likewise.
2378 * mutex.c: Likewise.

2406 * internals.h (__RES_PTHREAD_INTERNAL): Define.
2408 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
2410 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
2411 object state is represented with additional bits which distinguish
2412 whether that state was set up in the current process, or
2413 in an ancestor process. If that state was set in an ancestor,
2414 it means that a fork happened while thread was executing the init
2415 function. In that case, the state is reset to NEVER.
2416 * mutex.c (__pthread_once_fork_prepare): New function.
2417 (__pthread_once_fork_child): Likewise
2418 (__pthread_once_fork_parent): Likewise
2419 (__pthread_reset_pthread_once): Removed.

2424 to clarify what happens under cancellation and forking.
2426 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
2428 * internals.h: New thread manager request type, REQ_KICK.
2429 * join.c (pthread_exit): main thread now calls exit() instead
2430 of _exit() in order to proper process cleanup.
2431 * manager.c (__pthread_manager): Do not terminate manager
2432 after unblocking main thread; wait for main thread's
2433 REQ_PROCESS_EXIT request instead.
2434 Also, added REQ_KICK case to handle new request; this just does
2436 * manager.c (pthread_exited): Do not terminate manager after
2437 unblocking main thread.
2438 * manager.c (__pthread_manager_sighandler): If the main thread
2439 is waiting for all other threads to die, send a REQ_KICK into
2440 the thread manager request pipe to get it to clean out the threads
2441 and unblock the main thread as soon as possible. This fixes
2442 the 2000 millisecond hang on shutdown bug.
2443 * Examples/ex7.c: New file, tests shutdown behavior when all threads
2444 including the main one call pthread_exit(), or implicitly do so.
2445 * Makefile (tests): Add ex7.
2447 2000-05-05 Andreas Jaeger <aj@suse.de>

2462 2000-04-29 Bruno Haible <haible@clisp.cons.org>
2464 * join.c (pthread_exit): Use THREAD_GETMEM_NC instead of THREAD_GETMEM
2465 for eventmask larger than 1 word.
2467 2000-04-27 Ulrich Drepper <drepper@redhat.com>
2469 * Versions [libpthread] (GLIBC_2.2): Add __pthread_initialize_minimal.

2471 minimal initialization.
2472 (pthread_initialize): Remove this code here.
2473 * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h" again. We
2474 are working around the problem in glibc.
2476 2000-04-25 Ulrich Drepper <drepper@redhat.com>
2478 * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
2479 now. First gcc must be fixed (more concrete: libgcc).
2481 2000-04-24 Ulrich Drepper <drepper@redhat.com>
2483 * pthread.c: Remove special treatement for interrupt handlers on x86.
2484 * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.
2485 * sysdeps/i386/useldt.h: Use "q" constraint instead of "r" where
2487 * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h".

2491 * join.c (pthread_exit): Set p_terminated after reporting the
2492 termination event instead of before.
2494 2000-04-20 Jakub Jelinek <jakub@redhat.com>
2496 * sysdeps/pthread/bits/libc-lock.h: Only declare __pthread_rwlock_*
2499 2000-04-18 Andreas Jaeger <aj@suse.de>

2520 * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
2521 (pthread_getcpuclockid): Don't compare thread_id with thread_self,
2522 use thread_handle().
2524 2000-04-16 Ulrich Drepper <drepper@redhat.com>
2526 * condvar.c (pthread_cond_timedwait_relative): Don't test for owner
2527 if fast mutex is used. Don't initialize `already_canceled' twice.
2528 Correctly test for return value of timedsuspend.
2530 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
2531 therefore don't need the _rt versions of the signal handlers.
2533 2000-04-15 Ulrich Drepper <drepper@redhat.com>
2535 * pthread.c (pthread_yield): New function.
2536 * sysdeps/pthread/pthread.h (pthread_yield): Add prototype.
2537 * Versions [libpthread] (GLIBC_2.2): Add pthread_yield.
2538 * internals.h: Declare __pthread_yield.
2540 * pthread.c (pthread_initialize): Avoid a bit more code if
2541 realtime signals are known to exist.
2543 * pthread.c: Is __ASSUME_REALTIME_SIGNALS then avoid generating code
2544 to dynamically detect RT signals and avoid generating compatibility
2545 functions with old kernel.
2546 * restart.h (restart) [__ASSUME_REALTIME_SIGNALS]: Use
2547 __pthread_restart_new directly.
2548 (suspend) [__ASSUME_REALTIME_SIGNALS]: Use

2566 suspension function through __pthread_timedsuspend.
2567 * semaphore.c (sem_timedwait): Use timedsuspend, don't duplicate
2569 Patch by Kaz Kylheku <kaz@ashi.footprints.net>.

2583 * weaks.c: Fix typo.
2585 * shlib-versions (mips.*-.*-linux.*): Support only GLIBC 2.0 and
2586 2.2 for linuxthreads.
2588 2000-04-13 Ulrich Drepper <drepper@redhat.com>
2590 * sysdeps/unix/sysv/linux/i386/getcpuclockid.c
2591 (pthread_getcpuclockid): Fix typo.

2863 Redesigned how cancellation unblocks a thread from internal
2864 cancellation points (sem_wait, pthread_join,
2865 pthread_cond_{wait,timedwait}).
2866 Cancellation won't eat a signal in any of these functions
2867 (*required* by POSIX and Single Unix Spec!).
2868 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
2869 simultaneous condition variable signal (not required by POSIX
2870 or Single Unix Spec, but nice).
2871 * spinlock.c: __pthread_lock queues back any received restarts
2872 that don't belong to it instead of assuming ownership of lock
2873 upon any restart; fastlock can no longer be acquired by two threads
2875 * restart.h: Restarts queue even on kernels that don't have
2876 queued real time signals (2.0, early 2.1), thanks to atomic counter,
2877 avoiding a rare race condition in pthread_cond_timedwait.

2919 pwrite64, lseek64, open64, and __open64.

2922 new_thread_bottom. Correct handling of stack size and when the
2923 rlimit method to guard for stack growth is used.
2924 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
2925 minus one pagesize (not two).
2927 1999-12-03 Andreas Jaeger <aj@suse.de>
2929 * Versions: Add __res_state with version GLIBC_2.2.
