2496 under [HAVE_TLS_SUPPORT] so we can rely on the initialization done

3759 same: pthread_mutexattr_settype() and pthread_mutexattr_gettype().
3760 Changes references to PTHREAD_MUTEXATTR_FAST_NP to
3761 PTHREAD_MUTEXATTR_ADAPTIVE_NP.
3762 Begins to introduce discussion of the ``timed'' mutex type. This

4094 node was not being properly enqueued, due to failing to update
4095 the lock->__status field.

4341 2000-06-19 H.J. Lu <hjl@gnu.org>
4343 * spinlock.h (HAS_COMPARE_AND_SWAP): Defined if
4344 HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS is defined.
4345 (compare_and_swap_with_release_semantics): New. Default to
4346 compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
4347 is not defined.
4349 * spinlock.c (__pthread_unlock): Call
4350 compare_and_swap_with_release_semantics () instead of
4351 compare_and_swap ().
4353 2000-06-19 Ulrich Drepper <drepper@redhat.com>
4355 * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning

4362 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4364 Timer nodes are now reference counted, and can be marked
4365 as deleted. This allows for the safe release of the global mutex
4366 in the middle without losing the timer being operated on.
4368 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
4369 member is now an enum with three values, so that an intermediate
4370 state can be represented (deleted but not free for reuse yet).
4371 New refcount member added.
4372 * sysdeps/pthread/timer_routines.c: Likewise.
4374 * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,

4378 restructured, recursive deadlock bug fixed.
4380 * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
4381 timer_addref to ensure that timer won't be deleted while mutex is not
4382 held. Also uses timer_invalid to perform validation of timer handle.
4383 * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
4384 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
4386 2000-06-14 Ulrich Drepper <drepper@redhat.com>
4388 * shlib-versions: Add entry for SH.
4389 Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
4391 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
4393 A few optimizations. Got rid of unnecessary wakeups of timer threads,
4394 tightened up some critical regions and micro-optimized some list
4395 manipulation code.
4397 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4398 Returns int value now to indicate whether timer was queued at head.
4399 * sysdeps/pthread/posix-timer.h: Likewise.
4400 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
4401 new return value from __timer_thread_queue_timer to avoid waking
4402 up timer thread unnecessarily.
4404 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4405 inuse flag, because this requires mutex to be held. Callers updated
4406 to do the check when they have the mutex.
4407 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4409 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4410 regions: avoids making system calls while holding timer mutex, and
4411 a few computations were moved outside of the mutex as well.
4412 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4414 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4415 to list_unlink_ip, meaning idempotent. Pointer manipulation
4416 changed to get better better code out of gcc.
4417 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4418 version of list_unlink added here.
4419 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4420 function in all places: idempotent one for timers, non-idempotent
4421 one for thread nodes.
4422 * sysdeps/pthread/timer_settime: Likewise.
4423 * sysdeps/pthread/timer_routines.c: Likewise.
4425 2000-06-13 Ulrich Drepper <drepper@redhat.com>
4427 * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.
4428 * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.
4430 * sysdeps/pthread/Makefile: Remove tests definition.
4432 2000-06-12 Kazumoto Kojima <kkojima@rr.iij4u.or.jp>

4444 2000-06-11 Geoff Keating <geoffk@cygnus.com>
4446 * sysdeps/powerpc/pspinlock.c (__pthread_spin_lock): Implement.
4447 (__pthread_spin_trylock): Implement.
4448 (__pthread_spin_unlock): Implement.
4449 (__pthread_spin_init): Implement.
4450 (__pthread_spin_destroy): Implement.
4452 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4454 * sysdeps/pthread/timer_routines.c (list_append): Little fix to
4455 really append the entry.
4457 2000-06-10 Andreas Jaeger <aj@suse.de>
4459 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
4461 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
4463 * sysdeps/pthread/timer_create.c: Thread matching now done on
4464 clock type as well as thread attributes.
4465 There are individual global signal-delivering threads for
4466 different clock types.
4467 * sysdeps/pthread/posix-timer.h: Likewise.
4468 * sysdeps/pthread/timer_routines.c: Likewise.
4470 * sysdeps/pthread/timer_routines.c: Thread allocation and
4471 deallocation function now remembers to put thread on active
4472 list and remove from active list.
4473 Thus now the feature of binding multiple timers
4474 to a single thread actually works.
4476 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4478 * pthread.c (__pthread_create_2_1): Optimize a bit.
4480 * internals.h (invalid_handle): Also test for p_terminated != 0.
4481 (nonexisting_handle): New function. Same as old invalid_handle.
4482 * join.c (pthread_join): Use nonexisting_handle instead of
4483 invalid_handle to test for acceptable thread handle.
4484 * manager.c (pthread_handle_free): Likewise.
4485 * joinrace.c: New file.
4486 Reported by Permaine Cheung <pcheung@cygnus.com>.
4488 2000-06-08 Ulrich Drepper <drepper@redhat.com>
4490 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4491 Correct handling of matching variable.
4493 * sysdeps/pthread/tst-timer.c (main): Rewrite initializers to
4494 avoid warnings.
4496 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
4497 Be prepared for empty timer list.
4499 * sysdeps/pthread/timer_create.c (timer_create): Correct names of
4500 CPUTIME clock ID. Add support for thread clocks.
4502 * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
4503 subtraction were switched.
4505 * sysdeps/pthread/timer_routines.c (init_module): Use
4506 THREAD_MAXNODES threads.
4508 * sysdeps/pthread/posix-timer.h (struct timer_node): Add creator_pid.
4509 * sysdeps/pthread/timer_create.c: Fill in creator_pid.
4510 * sysdeps/pthread/timer_routines.c (thread_expire_timer): Send signal
4511 with sigqueueinfo is this system call is available.
4513 * sysdeps/pthread/timer_create.c (timer_create): Allow
4514 CLOCK_CPUTIME if _POSIX_CPUTIME is defined.
4516 * sysdeps/pthread/Makefile: New file. Add rules to build timer
4517 functionality.
4518 * sysdeps/unix/sysv/linux/bits/local_lim.h: Add TIMER_MAX.
4520 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>

4531 2000-06-08 Ulrich Drepper <drepper@redhat.com>
4533 * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and
4534 LINK_MAX definitions if necessary.
4536 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
4538 Added missing fork time handling of global libio lock.
4540 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4541 not just the individual stream locks. Rewritten to use new
4542 iterator interface provided by libio rather than accessing
4543 global variable.
4545 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4546 which lock and unlock the stream list using the new interface
4547 provied by libio.
4548 * internals.h: Likewise.
4550 * ptfork.c (__fork): Now calls __flockfilelist before fork,
4551 and __funlockfilelist in the parent after the fork.
4552 Child still calls __fresetlockfiles as before.
4554 * linuxthreads.texi: Now explains what happens to streams at
4555 fork time. Also whole new section on forking and thread added.
4556 Definition of pthread_atfork moved out of Miscellaneous Functions
4557 to this new section.
4559 2000-06-04 Jakub Jelinek <jakub@redhat.com>
4561 * sysdeps/sparc/sparc32/sparcv9/pspinlock.c (__pthread_spin_lock):

4580 * Examples/ex8.c: New file.
4582 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
4584 Bugfix: The pthread_atfork mechanism now takes care of its
4585 own internal mutex at fork time.
4587 * ptfork.c (__fork): Revised so that the mutex is held across
4588 the fork operation and while the handlers are called, and so that
4589 the child resets the mutex.
4591 * linuxthreads.texi: Updated pthread_atfork documentation to make
4592 it clear that fork and pthread_atfork can't be reentered from
4593 atfork handlers, that pthread_atfork and fork are mutually atomic,
4594 and that the handlers are inherited by the child process.
4596 2000-05-24 Ulrich Drepper <drepper@redhat.com>
4598 * Makefile (libpthread-routines): Add pspinlock.
4599 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

4633 * internals.h (__RES_PTHREAD_INTERNAL): Define.
4635 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
4637 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
4638 object state is represented with additional bits which distinguish
4639 whether that state was set up in the current process, or
4640 in an ancestor process. If that state was set in an ancestor,
4641 it means that a fork happened while thread was executing the init
4642 function. In that case, the state is reset to NEVER.
4643 * mutex.c (__pthread_once_fork_prepare): New function.
4644 (__pthread_once_fork_child): Likewise
4645 (__pthread_once_fork_parent): Likewise
4646 (__pthread_reset_pthread_once): Removed.
4647 * ptfork.c (__fork): Call new handlers in mutex.c.
4648 * internals.h: Declarations of new mutex.c functions added.
4649 Declaration of removed function deleted.
4650 * linuxthreads.texi: Updated documentation about pthread_once
4651 to clarify what happens under cancellation and forking.
4653 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
4655 * internals.h: New thread manager request type, REQ_KICK.
4656 * join.c (pthread_exit): main thread now calls exit() instead
4657 of _exit() in order to proper process cleanup.
4658 * manager.c (__pthread_manager): Do not terminate manager
4659 after unblocking main thread; wait for main thread's
4660 REQ_PROCESS_EXIT request instead.
4661 Also, added REQ_KICK case to handle new request; this just does
4662 nothing.
4663 * manager.c (pthread_exited): Do not terminate manager after
4664 unblocking main thread.
4665 * manager.c (__pthread_manager_sighandler): If the main thread
4666 is waiting for all other threads to die, send a REQ_KICK into
4667 the thread manager request pipe to get it to clean out the threads
4668 and unblock the main thread as soon as possible. This fixes
4669 the 2000 millisecond hang on shutdown bug.
4670 * Examples/ex7.c: New file, tests shutdown behavior when all threads
4671 including the main one call pthread_exit(), or implicitly do so.
4672 * Makefile (tests): Add ex7.
4674 2000-05-05 Andreas Jaeger <aj@suse.de>
4676 * sysdeps/unix/sysv/linux/i386/getcpuclockid.c

4689 2000-04-29 Bruno Haible <haible@clisp.cons.org>
4691 * join.c (pthread_exit): Use THREAD_GETMEM_NC instead of THREAD_GETMEM
4692 for eventmask larger than 1 word.
4694 2000-04-27 Ulrich Drepper <drepper@redhat.com>

4697 * pthread.c (__pthread_initialize_minimal): New function. Perform
4698 minimal initialization.
4699 (pthread_initialize): Remove this code here.
4700 * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h" again. We
4701 are working around the problem in glibc.
4703 2000-04-25 Ulrich Drepper <drepper@redhat.com>
4705 * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
4706 now. First gcc must be fixed (more concrete: libgcc).
4708 2000-04-24 Ulrich Drepper <drepper@redhat.com>
4710 * pthread.c: Remove special treatement for interrupt handlers on x86.
4711 * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.

4718 * join.c (pthread_exit): Set p_terminated after reporting the
4719 termination event instead of before.
4721 2000-04-20 Jakub Jelinek <jakub@redhat.com>
4723 * sysdeps/pthread/bits/libc-lock.h: Only declare __pthread_rwlock_*
4724 if __USE_UNIX98.

4738 not stbar.
4739 (READ_MEMORY_BARRIER): Define.

4754 if fast mutex is used. Don't initialize `already_canceled' twice.
4755 Correctly test for return value of timedsuspend.
4757 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and

5088 2000-01-03 Kaz Kylheku <kaz@ashi.footprints.net>
5090 Redesigned how cancellation unblocks a thread from internal
5091 cancellation points (sem_wait, pthread_join,
5092 pthread_cond_{wait,timedwait}).
5093 Cancellation won't eat a signal in any of these functions
5094 (*required* by POSIX and Single Unix Spec!).
5095 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
5096 simultaneous condition variable signal (not required by POSIX
5097 or Single Unix Spec, but nice).
5098 * spinlock.c: __pthread_lock queues back any received restarts
5099 that don't belong to it instead of assuming ownership of lock
5100 upon any restart; fastlock can no longer be acquired by two threads
5101 simultaneously.
5102 * restart.h: Restarts queue even on kernels that don't have
5103 queued real time signals (2.0, early 2.1), thanks to atomic counter,
5104 avoiding a rare race condition in pthread_cond_timedwait.
5106 1999-12-31 Andreas Jaeger <aj@suse.de>
5108 * internals.h: Remove duplicate prototype declarations.
5110 * weaks.c: Remove __THROW from prototypes since the file is not

5145 * wrapsyscall.c: Define pread, __pread64, pread64, pwrite, __pwrite64,
5146 pwrite64, lseek64, open64, and __open64.
5148 * manager.c (pthread_allocate_stack): Correct computation of
5149 new_thread_bottom. Correct handling of stack size and when the
5150 rlimit method to guard for stack growth is used.
5151 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
5152 minus one pagesize (not two).
5154 1999-12-03 Andreas Jaeger <aj@suse.de>
5156 * Versions: Add __res_state with version GLIBC_2.2.
5158 * errno.c (__res_state): New function to return thread specific
5159 resolver state.
5161 * pthread.c (pthread_initialize): Initialize p_resp.
5162 (__pthread_reset_main_thread): Also set p_resp.
5164 * manager.c (pthread_handle_create): Initialize p_resp.
5166 * internals.h: Add thread specific resolver state.

6364 Since sigset_t no longer fits in a register, we can't pass in the
6365 thread's initial mask so easily. Take this opportunity to simplify
6366 the clone implementation by only accepting a single void* argument.
6368 * manager.c (__pthread_manager): Put thread vitals in the thread
6369 struct instead of as arguments through clone.
6370 (pthread_start_thread): Look for them there.
6371 * internals.h (struct _pthread): Add p_initial_fn,
6372 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
6373 * pthread.c (pthread_initialize_manager): Revise clone invocation.
