340 under [HAVE_TLS_SUPPORT] so we can rely on the initialization done
341 by the first thread's early TLS setup.
343 2002-08-15 Roland McGrath <roland@redhat.com>
345 * sysdeps/i386/tls.h (TLS_INIT_TP): Use statement expression and

2208 Timer nodes are now reference counted, and can be marked
2209 as deleted. This allows for the safe release of the global mutex
2210 in the middle without losing the timer being operated on.
2212 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
2213 member is now an enum with three values, so that an intermediate
2214 state can be represented (deleted but not free for reuse yet).
2215 New refcount member added.

2222 restructured, recursive deadlock bug fixed.
2224 * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
2225 timer_addref to ensure that timer won't be deleted while mutex is not
2226 held. Also uses timer_invalid to perform validation of timer handle.
2227 * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
2228 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.

2235 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
2237 A few optimizations. Got rid of unnecessary wakeups of timer threads,
2238 tightened up some critical regions and micro-optimized some list
2239 manipulation code.
2241 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
2242 Returns int value now to indicate whether timer was queued at head.
2243 * sysdeps/pthread/posix-timer.h: Likewise.
2244 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
2245 new return value from __timer_thread_queue_timer to avoid waking
2246 up timer thread unnecessarily.
2248 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
2249 inuse flag, because this requires mutex to be held. Callers updated
2250 to do the check when they have the mutex.
2251 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
2253 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
2254 regions: avoids making system calls while holding timer mutex, and
2255 a few computations were moved outside of the mutex as well.
2256 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
2258 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
2259 to list_unlink_ip, meaning idempotent. Pointer manipulation
2260 changed to get better better code out of gcc.
2261 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
2262 version of list_unlink added here.
2263 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
2264 function in all places: idempotent one for timers, non-idempotent
2265 one for thread nodes.
2266 * sysdeps/pthread/timer_settime: Likewise.
2267 * sysdeps/pthread/timer_routines.c: Likewise.
2269 2000-06-13 Ulrich Drepper <drepper@redhat.com>

2299 really append the entry.
2301 2000-06-10 Andreas Jaeger <aj@suse.de>
2303 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
2305 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
2307 * sysdeps/pthread/timer_create.c: Thread matching now done on
2308 clock type as well as thread attributes.
2309 There are individual global signal-delivering threads for
2310 different clock types.
2311 * sysdeps/pthread/posix-timer.h: Likewise.
2312 * sysdeps/pthread/timer_routines.c: Likewise.
2314 * sysdeps/pthread/timer_routines.c: Thread allocation and
2315 deallocation function now remembers to put thread on active
2316 list and remove from active list.
2317 Thus now the feature of binding multiple timers
2318 to a single thread actually works.
2320 2000-06-10 Ulrich Drepper <drepper@redhat.com>
2322 * pthread.c (__pthread_create_2_1): Optimize a bit.
2324 * internals.h (invalid_handle): Also test for p_terminated != 0.
2325 (nonexisting_handle): New function. Same as old invalid_handle.
2326 * join.c (pthread_join): Use nonexisting_handle instead of
2327 invalid_handle to test for acceptable thread handle.
2328 * manager.c (pthread_handle_free): Likewise.
2329 * joinrace.c: New file.
2330 Reported by Permaine Cheung <pcheung@cygnus.com>.
2332 2000-06-08 Ulrich Drepper <drepper@redhat.com>
2334 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):

2338 avoid warnings.
2340 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
2341 Be prepared for empty timer list.
2343 * sysdeps/pthread/timer_create.c (timer_create): Correct names of
2344 CPUTIME clock ID. Add support for thread clocks.
2346 * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
2347 subtraction were switched.
2349 * sysdeps/pthread/timer_routines.c (init_module): Use
2350 THREAD_MAXNODES threads.
2352 * sysdeps/pthread/posix-timer.h (struct timer_node): Add creator_pid.

2355 with sigqueueinfo is this system call is available.
2357 * sysdeps/pthread/timer_create.c (timer_create): Allow
2358 CLOCK_CPUTIME if _POSIX_CPUTIME is defined.
2360 * sysdeps/pthread/Makefile: New file. Add rules to build timer
2361 functionality.
2362 * sysdeps/unix/sysv/linux/bits/local_lim.h: Add TIMER_MAX.

2378 LINK_MAX definitions if necessary.
2380 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
2382 Added missing fork time handling of global libio lock.
2384 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
2385 not just the individual stream locks. Rewritten to use new
2386 iterator interface provided by libio rather than accessing
2387 global variable.
2389 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
2390 which lock and unlock the stream list using the new interface
2391 provied by libio.
2392 * internals.h: Likewise.
2394 * ptfork.c (__fork): Now calls __flockfilelist before fork,
2395 and __funlockfilelist in the parent after the fork.
2396 Child still calls __fresetlockfiles as before.
2398 * linuxthreads.texi: Now explains what happens to streams at
2399 fork time. Also whole new section on forking and thread added.
2400 Definition of pthread_atfork moved out of Miscellaneous Functions
2401 to this new section.
2403 2000-06-04 Jakub Jelinek <jakub@redhat.com>
2405 * sysdeps/sparc/sparc32/sparcv9/pspinlock.c (__pthread_spin_lock):

2426 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
2428 Bugfix: The pthread_atfork mechanism now takes care of its
2429 own internal mutex at fork time.
2431 * ptfork.c (__fork): Revised so that the mutex is held across
2432 the fork operation and while the handlers are called, and so that
2433 the child resets the mutex.
2435 * linuxthreads.texi: Updated pthread_atfork documentation to make
2436 it clear that fork and pthread_atfork can't be reentered from
2437 atfork handlers, that pthread_atfork and fork are mutually atomic,
2438 and that the handlers are inherited by the child process.
2440 2000-05-24 Ulrich Drepper <drepper@redhat.com>
2442 * Makefile (libpthread-routines): Add pspinlock.
2443 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

2479 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
2481 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
2482 object state is represented with additional bits which distinguish
2483 whether that state was set up in the current process, or
2484 in an ancestor process. If that state was set in an ancestor,
2485 it means that a fork happened while thread was executing the init
2486 function. In that case, the state is reset to NEVER.
2487 * mutex.c (__pthread_once_fork_prepare): New function.
2488 (__pthread_once_fork_child): Likewise
2489 (__pthread_once_fork_parent): Likewise
2490 (__pthread_reset_pthread_once): Removed.

2495 to clarify what happens under cancellation and forking.
2497 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
2499 * internals.h: New thread manager request type, REQ_KICK.
2500 * join.c (pthread_exit): main thread now calls exit() instead
2501 of _exit() in order to proper process cleanup.
2502 * manager.c (__pthread_manager): Do not terminate manager
2503 after unblocking main thread; wait for main thread's
2504 REQ_PROCESS_EXIT request instead.
2505 Also, added REQ_KICK case to handle new request; this just does
2506 nothing.
2507 * manager.c (pthread_exited): Do not terminate manager after
2508 unblocking main thread.
2509 * manager.c (__pthread_manager_sighandler): If the main thread
2510 is waiting for all other threads to die, send a REQ_KICK into
2511 the thread manager request pipe to get it to clean out the threads
2512 and unblock the main thread as soon as possible. This fixes
2513 the 2000 millisecond hang on shutdown bug.
2514 * Examples/ex7.c: New file, tests shutdown behavior when all threads
2515 including the main one call pthread_exit(), or implicitly do so.
2516 * Makefile (tests): Add ex7.
2518 2000-05-05 Andreas Jaeger <aj@suse.de>

2598 if fast mutex is used. Don't initialize `already_canceled' twice.
2599 Correctly test for return value of timedsuspend.
2601 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and

2908 2000-01-12 Ulrich Drepper <drepper@cygnus.com>
2910 * internals.h (pthread_readlock_info): New structure.
2911 (_pthread_descr_struct): Add p_readlock_list, p_readlock_free, and

2932 2000-01-03 Kaz Kylheku <kaz@ashi.footprints.net>
2934 Redesigned how cancellation unblocks a thread from internal
2935 cancellation points (sem_wait, pthread_join,
2936 pthread_cond_{wait,timedwait}).
2937 Cancellation won't eat a signal in any of these functions
2938 (*required* by POSIX and Single Unix Spec!).
2939 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
2940 simultaneous condition variable signal (not required by POSIX
2941 or Single Unix Spec, but nice).
2942 * spinlock.c: __pthread_lock queues back any received restarts
2943 that don't belong to it instead of assuming ownership of lock
2944 upon any restart; fastlock can no longer be acquired by two threads
2945 simultaneously.
2946 * restart.h: Restarts queue even on kernels that don't have
2947 queued real time signals (2.0, early 2.1), thanks to atomic counter,
2948 avoiding a rare race condition in pthread_cond_timedwait.
2950 1999-12-31 Andreas Jaeger <aj@suse.de>
2952 * internals.h: Remove duplicate prototype declarations.

2987 * Versions: Export pread, __pread64, pread64, pwrite, __pwrite64,
2988 pwrite64, lseek64, open64, and __open64.
2989 * wrapsyscall.c: Define pread, __pread64, pread64, pwrite, __pwrite64,
2990 pwrite64, lseek64, open64, and __open64.
2992 * manager.c (pthread_allocate_stack): Correct computation of
2993 new_thread_bottom. Correct handling of stack size and when the
2994 rlimit method to guard for stack growth is used.
2995 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
2996 minus one pagesize (not two).
2998 1999-12-03 Andreas Jaeger <aj@suse.de>
3000 * Versions: Add __res_state with version GLIBC_2.2.
3002 * errno.c (__res_state): New function to return thread specific
3003 resolver state.
3005 * pthread.c (pthread_initialize): Initialize p_resp.
3006 (__pthread_reset_main_thread): Also set p_resp.
3008 * manager.c (pthread_handle_create): Initialize p_resp.
3010 * internals.h: Add thread specific resolver state.

4208 Since sigset_t no longer fits in a register, we can't pass in the

4213 struct instead of as arguments through clone.

4216 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
