21 LINK_MAX definitions if necessary.
23 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
25 Added missing fork time handling of global libio lock.
27 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
28 not just the individual stream locks. Rewritten to use new
29 iterator interface provided by libio rather than accessing
32 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
33 which lock and unlock the stream list using the new interface
35 * internals.h: Likewise.
37 * ptfork.c (__fork): Now calls __flockfilelist before fork,
38 and __funlockfilelist in the parent after the fork.
39 Child still calls __fresetlockfiles as before.

42 fork time. Also whole new section on forking and thread added.

69 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
71 Bugfix: The pthread_atfork mechanism now takes care of its
72 own internal mutex at fork time.
74 * ptfork.c (__fork): Revised so that the mutex is held across
75 the fork operation and while the handlers are called, and so that
76 the child resets the mutex.
78 * linuxthreads.texi: Updated pthread_atfork documentation to make
79 it clear that fork and pthread_atfork can't be reentered from
80 atfork handlers, that pthread_atfork and fork are mutually atomic,
81 and that the handlers are inherited by the child process.
83 2000-05-24 Ulrich Drepper <drepper@redhat.com>
85 * Makefile (libpthread-routines): Add pspinlock.
86 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.

122 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
124 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
125 object state is represented with additional bits which distinguish
126 whether that state was set up in the current process, or
127 in an ancestor process. If that state was set in an ancestor,
128 it means that a fork happened while thread was executing the init
129 function. In that case, the state is reset to NEVER.
130 * mutex.c (__pthread_once_fork_prepare): New function.
131 (__pthread_once_fork_child): Likewise
132 (__pthread_once_fork_parent): Likewise

146 after unblocking main thread; wait for main thread's
147 REQ_PROCESS_EXIT request instead.
148 Also, added REQ_KICK case to handle new request; this just does
150 * manager.c (pthread_exited): Do not terminate manager after
151 unblocking main thread.
152 * manager.c (__pthread_manager_sighandler): If the main thread
153 is waiting for all other threads to die, send a REQ_KICK into
154 the thread manager request pipe to get it to clean out the threads
155 and unblock the main thread as soon as possible. This fixes
156 the 2000 millisecond hang on shutdown bug.
157 * Examples/ex7.c: New file, tests shutdown behavior when all threads
158 including the main one call pthread_exit(), or implicitly do so.
159 * Makefile (tests): Add ex7.
161 2000-05-05 Andreas Jaeger <aj@suse.de>

241 if fast mutex is used. Don't initialize `already_canceled' twice.
242 Correctly test for return value of timedsuspend.

245 therefore don't need the _rt versions of the signal handlers.

258 to dynamically detect RT signals and avoid generating compatibility
259 functions with old kernel.

548 PTHREAD_RWLOCK_PREFER_WRITER_NONRECURSIVE_NP.
549 Patches by Kaz Kylheku <kaz@ashi.footprints.net>.
551 2000-01-12 Ulrich Drepper <drepper@cygnus.com>
553 * internals.h (pthread_readlock_info): New structure.
554 (_pthread_descr_struct): Add p_readlock_list, p_readlock_free, and
555 p_untracked_readlock_count.
556 * pthread.c (__pthread_initial_thread, pthread_manager_thread):
557 Add initializers for new fields.
558 * manager.c (pthread_free): Free read/write lock lists.
559 * queue.h (queue_is_empty): New function.
560 * rwlock.c: Implement requirements about when readers should get
562 * sysdeps/pthread/pthread.h
563 (PTHREAD_RWLOCK_PREFER_WRITER_NONRECURSIVE_NP): New definition.
564 * sysdeps/pthread/bits/pthreadtypes.h (struct _pthread_rwlock_t):
565 Define this name as well.
566 Patches by Kaz Kylheku <kaz@ashi.footprints.net>.
568 2000-01-05 Ulrich Drepper <drepper@cygnus.com>
570 * pthread.c (__pthread_initial_thread, pthread_manager_thread):

572 * internals.h (struct _pthread_descr_struct): Move new elements to
575 2000-01-03 Kaz Kylheku <kaz@ashi.footprints.net>
577 Redesigned how cancellation unblocks a thread from internal
578 cancellation points (sem_wait, pthread_join,
579 pthread_cond_{wait,timedwait}).
580 Cancellation won't eat a signal in any of these functions
581 (*required* by POSIX and Single Unix Spec!).
582 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
583 simultaneous condition variable signal (not required by POSIX
584 or Single Unix Spec, but nice).
585 * spinlock.c: __pthread_lock queues back any received restarts
586 that don't belong to it instead of assuming ownership of lock
587 upon any restart; fastlock can no longer be acquired by two threads
589 * restart.h: Restarts queue even on kernels that don't have
590 queued real time signals (2.0, early 2.1), thanks to atomic counter,
591 avoiding a rare race condition in pthread_cond_timedwait.
593 1999-12-31 Andreas Jaeger <aj@suse.de>
595 * internals.h: Remove duplicate prototype declarations.

632 * wrapsyscall.c: Define pread, __pread64, pread64, pwrite, __pwrite64,
633 pwrite64, lseek64, open64, and __open64.

636 new_thread_bottom. Correct handling of stack size and when the
637 rlimit method to guard for stack growth is used.
638 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
639 minus one pagesize (not two).
641 1999-12-03 Andreas Jaeger <aj@suse.de>
643 * Versions: Add __res_state with version GLIBC_2.2.

726 and pthread_handle_sigcancel with functions that restore
727 %gs from the signal context. For each signal handling function,
728 two wrappers are required, one for a non-RT signal and one for
