4568 Timer nodes are now reference counted, and can be marked
4569 as deleted. This allows for the safe release of the global mutex
4570 in the middle without losing the timer being operated on.
4572 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
4573 member is now an enum with three values, so that an intermediate

4602 Returns int value now to indicate whether timer was queued at head.
4603 * sysdeps/pthread/posix-timer.h: Likewise.
4604 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of

4606 up timer thread unnecessarily.
4608 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
4609 inuse flag, because this requires mutex to be held. Callers updated
4610 to do the check when they have the mutex.
4611 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
4613 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
4614 regions: avoids making system calls while holding timer mutex, and
4615 a few computations were moved outside of the mutex as well.
4616 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
4618 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
4619 to list_unlink_ip, meaning idempotent. Pointer manipulation
4620 changed to get better better code out of gcc.
4621 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
4622 version of list_unlink added here.
4623 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
4624 function in all places: idempotent one for timers, non-idempotent
4625 one for thread nodes.
4626 * sysdeps/pthread/timer_settime: Likewise.
4627 * sysdeps/pthread/timer_routines.c: Likewise.

4659 really append the entry.
4661 2000-06-10 Andreas Jaeger <aj@suse.de>
4663 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
4665 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
4667 * sysdeps/pthread/timer_create.c: Thread matching now done on
4668 clock type as well as thread attributes.
4669 There are individual global signal-delivering threads for
4670 different clock types.
4671 * sysdeps/pthread/posix-timer.h: Likewise.
4672 * sysdeps/pthread/timer_routines.c: Likewise.
4674 * sysdeps/pthread/timer_routines.c: Thread allocation and
4675 deallocation function now remembers to put thread on active
4676 list and remove from active list.
4677 Thus now the feature of binding multiple timers
4678 to a single thread actually works.
4680 2000-06-10 Ulrich Drepper <drepper@redhat.com>
4682 * pthread.c (__pthread_create_2_1): Optimize a bit.
4684 * internals.h (invalid_handle): Also test for p_terminated != 0.

4738 LINK_MAX definitions if necessary.
4740 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
4742 Added missing fork time handling of global libio lock.
4744 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
4745 not just the individual stream locks. Rewritten to use new
4746 iterator interface provided by libio rather than accessing
4749 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
4750 which lock and unlock the stream list using the new interface
4752 * internals.h: Likewise.
4754 * ptfork.c (__fork): Now calls __flockfilelist before fork,
4755 and __funlockfilelist in the parent after the fork.
4756 Child still calls __fresetlockfiles as before.
4758 * linuxthreads.texi: Now explains what happens to streams at
4759 fork time. Also whole new section on forking and thread added.

4788 Bugfix: The pthread_atfork mechanism now takes care of its
4789 own internal mutex at fork time.
4791 * ptfork.c (__fork): Revised so that the mutex is held across
4792 the fork operation and while the handlers are called, and so that
4793 the child resets the mutex.
4795 * linuxthreads.texi: Updated pthread_atfork documentation to make
4796 it clear that fork and pthread_atfork can't be reentered from
4797 atfork handlers, that pthread_atfork and fork are mutually atomic,
4798 and that the handlers are inherited by the child process.

4842 object state is represented with additional bits which distinguish
4843 whether that state was set up in the current process, or
4844 in an ancestor process. If that state was set in an ancestor,
4845 it means that a fork happened while thread was executing the init
4846 function. In that case, the state is reset to NEVER.

4860 * join.c (pthread_exit): main thread now calls exit() instead
4861 of _exit() in order to proper process cleanup.
4862 * manager.c (__pthread_manager): Do not terminate manager
4863 after unblocking main thread; wait for main thread's
4864 REQ_PROCESS_EXIT request instead.
4865 Also, added REQ_KICK case to handle new request; this just does
4867 * manager.c (pthread_exited): Do not terminate manager after
4868 unblocking main thread.
4869 * manager.c (__pthread_manager_sighandler): If the main thread
4870 is waiting for all other threads to die, send a REQ_KICK into
4871 the thread manager request pipe to get it to clean out the threads
4872 and unblock the main thread as soon as possible. This fixes
4873 the 2000 millisecond hang on shutdown bug.
4874 * Examples/ex7.c: New file, tests shutdown behavior when all threads
4875 including the main one call pthread_exit(), or implicitly do so.

4958 if fast mutex is used. Don't initialize `already_canceled' twice.
4959 Correctly test for return value of timedsuspend.
4961 * pthread.c: Correct long-time braino. We never set SA_SIGINFO and
4962 therefore don't need the _rt versions of the signal handlers.

5294 Redesigned how cancellation unblocks a thread from internal
5295 cancellation points (sem_wait, pthread_join,
5296 pthread_cond_{wait,timedwait}).
5297 Cancellation won't eat a signal in any of these functions
5298 (*required* by POSIX and Single Unix Spec!).
5299 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
5300 simultaneous condition variable signal (not required by POSIX
5301 or Single Unix Spec, but nice).
5302 * spinlock.c: __pthread_lock queues back any received restarts
5303 that don't belong to it instead of assuming ownership of lock
5304 upon any restart; fastlock can no longer be acquired by two threads
5306 * restart.h: Restarts queue even on kernels that don't have
5307 queued real time signals (2.0, early 2.1), thanks to atomic counter,
5308 avoiding a rare race condition in pthread_cond_timedwait.
5310 1999-12-31 Andreas Jaeger <aj@suse.de>
5312 * internals.h: Remove duplicate prototype declarations.

5348 pwrite64, lseek64, open64, and __open64.
5349 * wrapsyscall.c: Define pread, __pread64, pread64, pwrite, __pwrite64,
5350 pwrite64, lseek64, open64, and __open64.
5352 * manager.c (pthread_allocate_stack): Correct computation of
5353 new_thread_bottom. Correct handling of stack size and when the
5354 rlimit method to guard for stack growth is used.
5355 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
5356 minus one pagesize (not two).
5358 1999-12-03 Andreas Jaeger <aj@suse.de>
5360 * Versions: Add __res_state with version GLIBC_2.2.
5362 * errno.c (__res_state): New function to return thread specific
5365 * pthread.c (pthread_initialize): Initialize p_resp.
5366 (__pthread_reset_main_thread): Also set p_resp.
5368 * manager.c (pthread_handle_create): Initialize p_resp.

6568 Since sigset_t no longer fits in a register, we can't pass in the
6569 thread's initial mask so easily. Take this opportunity to simplify
6570 the clone implementation by only accepting a single void* argument.
6572 * manager.c (__pthread_manager): Put thread vitals in the thread
6573 struct instead of as arguments through clone.
6574 (pthread_start_thread): Look for them there.
6575 * internals.h (struct _pthread): Add p_initial_fn,
6576 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
6577 * pthread.c (pthread_initialize_manager): Revise clone invocation.
