(pthread_mutex_getprioceiling): Do not create mutex, just return ENOSYS. (pthread_mutex_lock): Simplify. (pthread_mutex_trylock): Remove unneeded local themutex. (pthread_mutex_unlock): Just return EPERM if mutex is not initialized. (pthread_mutex_setprioceiling): Do not create mutex, just return ENOSYS. * thread.h (verifyable_object_isvalid): Support up to three static initializers. (verifyable_object_isvalid (void const *,long)): Remove prototype. (pthread_mutex::init): Add optional initializer to parameter list.
* * exceptions.cc (setup_handler): Signal event for any sigwaitinfo if it existsChristopher Faylor2004-02-261-18/+25
| | | | | | | | | | | | | | | | | | | | | to force signal to be handled. Zero event here to prevent races. * signal.cc (sigwaitinfo): Use local handle value for everything since signal thread could zero event element at any time. Detect when awaking due to thread not in mask and set return value and errno accordingly. Don't set signal number to zero unless we've recognized the signal. * sigproc.cc (sigq): Rename from sigqueue throughout. * thread.cc (pthread::join): Handle signals received while waiting for thread to terminate. * cygwin.din: Export sighold, sigqueue. * exceptions.cc (sighold): Define new function. * signal.cc (handle_sigprocmask): Set correct errno for invalid signal. Simplify debugging output. (sigqueue): Define new function. * include/cygwin/signal.h (sighold): Declare new function. (sigqueue): Ditto. * include/cygwin/version.h: Bump API minor version number. * include/limits.h (TIMER_MAX): Define. (_POSIX_TIMER_MAX): Ditto.
* * thread.cc (pthread::cancelable_wait): Rearrange slightly.Corinna Vinschen2004-02-241-24/+47
| | | | | | | | | | | | | | | Add do_sig_wait parameter. Wait for signal_arrived if set to true. Return WAIT_SIGNALED if signal arrived. (pthread_cond::wait): Accomodate change to pthread::cancelable_wait. (pthread::join): Ditto. (semaphore::_timedwait): Ditto. (semaphore::_wait): Ditto. Change to return int to allow status feedback. (semaphore::wait): Return return value from semaphore::_wait. * thread.h (WAIT_SIGNALED): New definition. (pthread::cancelable_wait): Change declaration. Define do_sig_wait as false by default to not interfere with existing calls accidentally. (semaphore::_wait): Declare int.
* * debug.h (console_printf): Define for non-debugging condition.Christopher Faylor2004-02-091-1/+1
| | | | | | | | | | | | | | * cygtls.h (_threadinfo::lock): Remove wait argument. (_threadinfo::interrupt_setup): Remove retaddr argument. * exceptions.cc (_threadinfo::interrupt_setup): Ditto. (_threadinfo::interrupt_now): Accommodate change to interrupt_setup argument. (setup_handler): Ditto. Always lock sig stack prior to determining interrupt method. * gendef (_sigfe): Correct thinko regarding cmpxchg. (_sigbe): Ditto. (_threadinfo::lock): Ditto. (_threadinfo::pop): Eliminate left-over stack unlock. * sigproc.cc (proc_subproc): Chnage debugging output to printed warning.
