Makefile.in: New #defines and friends for Thread.h. * Makefile.in: New #defines and friends for Thread.h. * posix-threads.cc: (struct starter): Remove `object'. (_Jv_CondWait): Use interruptable condition variables and new recursive mutexes. New return codes on interrupt or non-ownership of mutex. (_Jv_CondNotify): Ditto. (_Jv_CondNotifyAll): Ditto. (_Jv_ThreadInterrupt): Set thread interrupt flag directly. Interrupt the target thread by signaling its wait condition. (_Jv_ThreadInitData): Set `thread_obj' in the thread data struct, not the starter struct. Initialize wait_mutex and wait_cond. (_Jv_MutexLock): New recursive mutex implementation. Moved from posix-threads.h. (_Jv_MutexUnlock): Ditto. (really_start): Set info->data->thread from pthread_self() to work around a race condition. Destroy wait_mutex and wait_cond when run() returns. * java/lang/Thread.java: (isInterrupted_): Renamed to overloaded `isInterrupted(boolean)'. Clear interrupted flag if clear_flag is set. startable_flag: New private field. (Thread): Initialize `startable_flag'. (toString): Check for null thread group. * java/lang/natThread.cc: (struct natThread): New fields `join_mutex', `join_cond'. Removed fields `joiner', `next'. (class locker): Removed. (initialize_native): Initialize `join_cond' and `join_mutex'. (interrupt): Now just calls _Jv_ThreadInterrupt(). (join): Simplified. Just wait on the target thread's join condition. (finish_): Remove join list code. Unset thread group. Signal potential joiners by notifying the dying threads join_cond. (start): Check for illegal restarts. * java/lang/natObject.cc: Check for return value of _Jv_CondWait and act appropriatly. * include/posix-threads.h: Remove all HAVE_RECURSIVE_MUTEX related #defines and #ifdefs. (struct _Jv_Thread_t): New fields `thread_obj', `wait_cond', `wait_mutex', `next'. (struct _Jv_ConditionVariable_t): Define as a struct instead of directly mapping to pthread_cond_t. (struct _Jv_Mutex_t): New recursive implementation. (_Jv_PthreadCheckMonitor): Reimplemented. Simple `owner' check. _Jv_HaveCondDestroy: Never define this for posix-threads. (_Jv_CondNotify): Remove inline implementation(s), prototype instead. (_Jv_CondNotifyAll): Ditto. (_Jv_MutexLock): Ditto. (_Jv_MutexUnlock): Ditto. (_Jv_MutexInit): Changed to reflect new mutex implementation. (_Jv_MutexDestroy): Ditto. (_Jv_CondDestroy): Removed. (_Jv_PthreadGetMutex): Removed. * include/win32-threads.h: (_Jv_CondNotify): Guess _JV_NOT_OWNER on an error. Add a FIXME about this. (_Jv_CondNotifyAll): Ditto. * win32-threads.cc: (_Jv_CondWait): Return 0 on a timeout. Guess _JV_NOT_OWNER on other errors. Add FIXME. From-SVN: r32773
