(allocate_stack): Call _dl_allocate_tls_init for user-provided stack. * cancellation.c: Renamed from cancelation.c. * Makefile: Adjust accordingly. * pthreadP.h (CANCELLATION_P): Renamed from CANCELATION_P. * cleanup_defer.c: Use CANCELLATION_P. * pthread_testcancel.c: Likewise. * descr.h: Fix spelling in comments. * init.c: Likewise. * pthread_getattr_np.c: Likewise. * pthread_getschedparam.c: Likewise. * pthread_setschedparam.c: Likewise. * Versions: Likewise. * pt-pselect.c: New file. * Makefile (libpthread-routines): Add pt-pselect. * Versions: Add pselect. * tst-cancel4.c: New file. * Makefile (tests): Add tst-cancel4. 2002-10-09 Ulrich Drepper * pthread_mutex_lock.c: Always record lock ownership. * pthread_mutex_timedlock.c: Likewise. * pthread_mutex_trylock.c: Likewise. * pt-readv.c: New file. * pt-writev.c: New file. * pt-creat.c: New file. * pt-msgrcv.c: New file. * pt-msgsnd.c: New file. * pt-poll.c: New file. * pt-select.c: New file. * pt-sigpause.c: New file. * pt-sigsuspend.c: New file. * pt-sigwait.c: New file. * pt-sigwaitinfo.c: New file. * pt-waitid.c: New file. * Makefile (libpthread-routines): Add pt-readv, pt-writev, pt-creat, pt-msgrcv, pt-msgsnd, pt-poll, pt-select, pt-sigpause, pt-sigsuspend, pt-sigwait, pt-sigwaitinfo, and pt-waitid. * Versions: Add all the new functions. * tst-exit1.c: New file. * Makefile (tests): Add tst-exit1. * sem_timedwait.c: Minor optimization for more optimal fastpath. 2002-10-08 Ulrich Drepper * pt-fcntl.c: Only enable asynchronous cancellation for F_SETLKW. * pthread_join.c: Enable asynchronous cancellation around lll_wait_tid call. pthread_join is an official cancellation point. * pthread_timedjoin.c: Likewise. * pthread_cond_wait.c: Revert order in which internal lock are dropped and the condvar's mutex are retrieved. * pthread_cond_timedwait.c: Likewise. Reported by dice@saros.East.Sun.COM. 2002-10-07 Ulrich Drepper * pthreadP.h: Cut out all type definitions and move them... * sysdeps/unix/sysv/linux/internaltypes.h: ...here. New file. * pthreadP.h: Include . * sysdeps/unix/sysv/linux/i386/lowlevelsem.h (lll_sem_post): Little performance tweaks. * sem_trywait.c: Shuffle #includes around to get right order. * sem_timedwait.c: Likewise. * sem_post.c: Likewise. * sem_wait.c: Likewise. * nptl 0.3 released. * Makefile (tests): Add tst-signal3. * tst-signal3.c: New file. 2002-10-05 Ulrich Drepper * sysdeps/unix/sysv/linux/i386/lowlevelsem.h: Tell the compiler that the asms modify the sem object. (__lll_sem_timedwait): Now takes struct sem* as first parameter. * sysdeps/unix/sysv/linux/i386/bits/semaphore.h (sem_t): Don't expose the actual members. * pthreadP.h (struct sem): New type. Actual semaphore type. * semaphoreP.h: Include pthreadP.h. * sem_getvalue.c: Adjust to sem_t change. * sem_init.c: Likewise. * sem_open.c: Likewise. * sem_post.c: Likewise. * sem_timedwait.c: Likewise. * sem_trywait.c: Likewise. * sem_wait.c: Likewise. 2002-10-04 Ulrich Drepper * Makefile (tests): Add tst-basic2, tst-exec1, tst-exec3, tst-exec3. * tst-basic2.c: New file. * tst-exec1.c: New file. * tst-exec2.c: New file. * tst-exec3.c: New file. * tst-fork1.c: Remove extra */. * nptl 0.2 released. The API for IA-32 is complete.
