326 under [HAVE_TLS_SUPPORT] so we can rely on the initialization done
327 by the first thread's early TLS setup.
329 2002-08-15 Roland McGrath <roland@redhat.com>
331 * sysdeps/i386/tls.h (TLS_INIT_TP): Use statement expression and

2194 Timer nodes are now reference counted, and can be marked
2195 as deleted. This allows for the safe release of the global mutex
2196 in the middle without losing the timer being operated on.
2198 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
2199 member is now an enum with three values, so that an intermediate
2200 state can be represented (deleted but not free for reuse yet).
2201 New refcount member added.

2211 timer_addref to ensure that timer won't be deleted while mutex is not
2212 held. Also uses timer_invalid to perform validation of timer handle.
2213 * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
2214 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.

2221 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
2223 A few optimizations. Got rid of unnecessary wakeups of timer threads,
2224 tightened up some critical regions and micro-optimized some list
2225 manipulation code.
2227 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
2228 Returns int value now to indicate whether timer was queued at head.
2229 * sysdeps/pthread/posix-timer.h: Likewise.
2230 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
2231 new return value from __timer_thread_queue_timer to avoid waking
2232 up timer thread unnecessarily.
2234 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
2235 inuse flag, because this requires mutex to be held. Callers updated
2236 to do the check when they have the mutex.
2237 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
2239 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
2240 regions: avoids making system calls while holding timer mutex, and
2241 a few computations were moved outside of the mutex as well.
2242 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
2244 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
2245 to list_unlink_ip, meaning idempotent. Pointer manipulation
2246 changed to get better better code out of gcc.
2247 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
2248 version of list_unlink added here.
2249 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
2250 function in all places: idempotent one for timers, non-idempotent
2251 one for thread nodes.
2252 * sysdeps/pthread/timer_settime: Likewise.
2253 * sysdeps/pthread/timer_routines.c: Likewise.

2287 2000-06-10 Andreas Jaeger <aj@suse.de>
2289 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
2291 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
2293 * sysdeps/pthread/timer_create.c: Thread matching now done on
2294 clock type as well as thread attributes.
2295 There are individual global signal-delivering threads for
2296 different clock types.
2297 * sysdeps/pthread/posix-timer.h: Likewise.
2298 * sysdeps/pthread/timer_routines.c: Likewise.
2300 * sysdeps/pthread/timer_routines.c: Thread allocation and
2301 deallocation function now remembers to put thread on active
2302 list and remove from active list.
2303 Thus now the feature of binding multiple timers
2304 to a single thread actually works.
2306 2000-06-10 Ulrich Drepper <drepper@redhat.com>
2308 * pthread.c (__pthread_create_2_1): Optimize a bit.
2310 * internals.h (invalid_handle): Also test for p_terminated != 0.
2311 (nonexisting_handle): New function. Same as old invalid_handle.
2312 * join.c (pthread_join): Use nonexisting_handle instead of
2313 invalid_handle to test for acceptable thread handle.
2314 * manager.c (pthread_handle_free): Likewise.
2315 * joinrace.c: New file.
2316 Reported by Permaine Cheung <pcheung@cygnus.com>.
2318 2000-06-08 Ulrich Drepper <drepper@redhat.com>

2327 Be prepared for empty timer list.
2329 * sysdeps/pthread/timer_create.c (timer_create): Correct names of
2330 CPUTIME clock ID. Add support for thread clocks.
2332 * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
2333 subtraction were switched.
2335 * sysdeps/pthread/timer_routines.c (init_module): Use
2336 THREAD_MAXNODES threads.

2364 LINK_MAX definitions if necessary.
2366 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
2368 Added missing fork time handling of global libio lock.
2370 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
2371 not just the individual stream locks. Rewritten to use new
2372 iterator interface provided by libio rather than accessing
2373 global variable.
2375 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
2376 which lock and unlock the stream list using the new interface
2377 provied by libio.
2378 * internals.h: Likewise.
2380 * ptfork.c (__fork): Now calls __flockfilelist before fork,
2381 and __funlockfilelist in the parent after the fork.
2382 Child still calls __fresetlockfiles as before.
2384 * linuxthreads.texi: Now explains what happens to streams at
2385 fork time. Also whole new section on forking and thread added.
2386 Definition of pthread_atfork moved out of Miscellaneous Functions
2387 to this new section.
2389 2000-06-04 Jakub Jelinek <jakub@redhat.com>

2412 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
2414 Bugfix: The pthread_atfork mechanism now takes care of its
2415 own internal mutex at fork time.
2417 * ptfork.c (__fork): Revised so that the mutex is held across
2418 the fork operation and while the handlers are called, and so that
2419 the child resets the mutex.
2421 * linuxthreads.texi: Updated pthread_atfork documentation to make
2422 it clear that fork and pthread_atfork can't be reentered from
2423 atfork handlers, that pthread_atfork and fork are mutually atomic,
2424 and that the handlers are inherited by the child process.
2426 2000-05-24 Ulrich Drepper <drepper@redhat.com>
2428 * Makefile (libpthread-routines): Add pspinlock.
2429 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

2465 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
2467 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
2468 object state is represented with additional bits which distinguish
2469 whether that state was set up in the current process, or
2470 in an ancestor process. If that state was set in an ancestor,
2471 it means that a fork happened while thread was executing the init
2472 function. In that case, the state is reset to NEVER.
2473 * mutex.c (__pthread_once_fork_prepare): New function.
2474 (__pthread_once_fork_child): Likewise
2475 (__pthread_once_fork_parent): Likewise
2476 (__pthread_reset_pthread_once): Removed.

2481 to clarify what happens under cancellation and forking.
2483 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
2485 * internals.h: New thread manager request type, REQ_KICK.
2486 * join.c (pthread_exit): main thread now calls exit() instead
2487 of _exit() in order to proper process cleanup.
2488 * manager.c (__pthread_manager): Do not terminate manager
2489 after unblocking main thread; wait for main thread's
2490 REQ_PROCESS_EXIT request instead.
2491 Also, added REQ_KICK case to handle new request; this just does
2492 nothing.
2493 * manager.c (pthread_exited): Do not terminate manager after
2494 unblocking main thread.
2495 * manager.c (__pthread_manager_sighandler): If the main thread
2496 is waiting for all other threads to die, send a REQ_KICK into
2497 the thread manager request pipe to get it to clean out the threads
2498 and unblock the main thread as soon as possible. This fixes
2499 the 2000 millisecond hang on shutdown bug.
2500 * Examples/ex7.c: New file, tests shutdown behavior when all threads
2501 including the main one call pthread_exit(), or implicitly do so.
2502 * Makefile (tests): Add ex7.
2504 2000-05-05 Andreas Jaeger <aj@suse.de>

2584 if fast mutex is used. Don't initialize `already_canceled' twice.
2585 Correctly test for return value of timedsuspend.
2587 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
2588 therefore don't need the _rt versions of the signal handlers.

2876 Patch by khendricks@ivey.uwo.ca (PR libc/1561).

2918 2000-01-03 Kaz Kylheku <kaz@ashi.footprints.net>
2920 Redesigned how cancellation unblocks a thread from internal
2921 cancellation points (sem_wait, pthread_join,
2922 pthread_cond_{wait,timedwait}).
2923 Cancellation won't eat a signal in any of these functions
2924 (*required* by POSIX and Single Unix Spec!).
2925 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
2926 simultaneous condition variable signal (not required by POSIX
2927 or Single Unix Spec, but nice).
2928 * spinlock.c: __pthread_lock queues back any received restarts
2929 that don't belong to it instead of assuming ownership of lock
2930 upon any restart; fastlock can no longer be acquired by two threads
2931 simultaneously.
2932 * restart.h: Restarts queue even on kernels that don't have
2933 queued real time signals (2.0, early 2.1), thanks to atomic counter,
2934 avoiding a rare race condition in pthread_cond_timedwait.
2936 1999-12-31 Andreas Jaeger <aj@suse.de>
2938 * internals.h: Remove duplicate prototype declarations.

2973 * Versions: Export pread, __pread64, pread64, pwrite, __pwrite64,
2974 pwrite64, lseek64, open64, and __open64.
2975 * wrapsyscall.c: Define pread, __pread64, pread64, pwrite, __pwrite64,
2976 pwrite64, lseek64, open64, and __open64.
2978 * manager.c (pthread_allocate_stack): Correct computation of
2979 new_thread_bottom. Correct handling of stack size and when the
2980 rlimit method to guard for stack growth is used.
2981 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
2982 minus one pagesize (not two).
2984 1999-12-03 Andreas Jaeger <aj@suse.de>
2986 * Versions: Add __res_state with version GLIBC_2.2.
2988 * errno.c (__res_state): New function to return thread specific
2989 resolver state.
2991 * pthread.c (pthread_initialize): Initialize p_resp.
2992 (__pthread_reset_main_thread): Also set p_resp.
2994 * manager.c (pthread_handle_create): Initialize p_resp.
2996 * internals.h: Add thread specific resolver state.

3018 (__pthread_initialize_manager): Respect event flags also for creation
3019 of the manager thread.
3021 1999-11-08 Ulrich Drepper <drepper@cygnus.com>
3023 * pthread.c (__pthread_initialize_manager): Initialize
3024 __pthread_manager_thread.p_tid.

4199 struct instead of as arguments through clone.
