3 * manager.c (pthread_handle_create): Initialize p_res._sock to -1.
5 2000-05-13 Jakub Jelinek <jakub@redhat.com>
7 * internals.h (__RES_PTHREAD_INTERNAL): Define.
9 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
11 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
12 object state is represented with additional bits which distinguish
13 whether that state was set up in the current process, or
14 in an ancestor process. If that state was set in an ancestor,
15 it means that a fork happened while thread was executing the init
16 function. In that case, the state is reset to NEVER.
17 * mutex.c (__pthread_once_fork_prepare): New function.
18 (__pthread_once_fork_child): Likewise
19 (__pthread_once_fork_parent): Likewise
20 (__pthread_reset_pthread_once): Removed.

29 * internals.h: New thread manager request type, REQ_KICK.
30 * join.c (pthread_exit): main thread now calls exit() instead
31 of _exit() in order to proper process cleanup.
32 * manager.c (__pthread_manager): Do not terminate manager
33 after unblocking main thread; wait for main thread's
34 REQ_PROCESS_EXIT request instead.
35 Also, added REQ_KICK case to handle new request; this just does
37 * manager.c (pthread_exited): Do not terminate manager after
38 unblocking main thread.
39 * manager.c (__pthread_manager_sighandler): If the main thread
40 is waiting for all other threads to die, send a REQ_KICK into
41 the thread manager request pipe to get it to clean out the threads
42 and unblock the main thread as soon as possible. This fixes
43 the 2000 millisecond hang on shutdown bug.
44 * Examples/ex7.c: New file, tests shutdown behavior when all threads
45 including the main one call pthread_exit(), or implicitly do so.
46 * Makefile (tests): Add ex7.
48 2000-05-05 Andreas Jaeger <aj@suse.de>

59 * sysdeps/i386/useldt.h (THREAD_SELF): Likewise.

72 minimal initialization.
73 (pthread_initialize): Remove this code here.

77 2000-04-25 Ulrich Drepper <drepper@redhat.com>
79 * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for

84 * pthread.c: Remove special treatement for interrupt handlers on x86.
85 * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.

100 2000-04-18 Andreas Jaeger <aj@suse.de>
102 * Versions: Use ld instead of ld.so.
104 2000-04-18 Jakub Jelinek <jakub@redhat.com>
106 * sysdeps/unix/sysv/linux/sparc/bits/sigcontext.h (struct sigcontext):

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

145 to dynamically detect RT signals and avoid generating compatibility
146 functions with old kernel.

462 2000-01-03 Kaz Kylheku <kaz@ashi.footprints.net>
464 Redesigned how cancellation unblocks a thread from internal
465 cancellation points (sem_wait, pthread_join,
466 pthread_cond_{wait,timedwait}).
467 Cancellation won't eat a signal in any of these functions
468 (*required* by POSIX and Single Unix Spec!).
469 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
470 simultaneous condition variable signal (not required by POSIX
471 or Single Unix Spec, but nice).
472 * spinlock.c: __pthread_lock queues back any received restarts
473 that don't belong to it instead of assuming ownership of lock
474 upon any restart; fastlock can no longer be acquired by two threads
476 * restart.h: Restarts queue even on kernels that don't have
477 queued real time signals (2.0, early 2.1), thanks to atomic counter,
478 avoiding a rare race condition in pthread_cond_timedwait.
480 1999-12-31 Andreas Jaeger <aj@suse.de>

520 pwrite64, lseek64, open64, and __open64.
522 * manager.c (pthread_allocate_stack): Correct computation of
523 new_thread_bottom. Correct handling of stack size and when the
524 rlimit method to guard for stack growth is used.
525 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
526 minus one pagesize (not two).
528 1999-12-03 Andreas Jaeger <aj@suse.de>
530 * Versions: Add __res_state with version GLIBC_2.2.

1740 Since sigset_t no longer fits in a register, we can't pass in the
1741 thread's initial mask so easily. Take this opportunity to simplify
1742 the clone implementation by only accepting a single void* argument.
1744 * linuxthreads/manager.c (__pthread_manager): Put thread vitals
1745 in the thread struct instead of as arguments through clone.
1746 (pthread_start_thread): Look for them there.
1747 * linuxthreads/internals.h (struct _pthread): Add p_initial_fn,
1748 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
1749 * linuxthreads/pthread.c (pthread_initialize_manager): Revise
