lock_wait(): Replaces lock_wait_suspend_thread(). Wait for the lock to be granted or the transaction to be killed using mysql_cond_timedwait() or mysql_cond_wait(). lock_wait_end(): Replaces que_thr_end_lock_wait() and lock_wait_release_thread_if_suspended(). lock_wait_timeout_task: Remove. The operating system kernel will resume the mysql_cond_timedwait() in lock_wait(). An added benefit is that innodb_lock_wait_timeout no longer has a 'jitter' of 1 second, which was caused by this wake-up task waking up only once per second, and then waking up any threads for which the timeout (which was only measured in seconds) was exceeded. innobase_kill_query(): Set trx->error_state=DB_INTERRUPTED, so that a call trx_is_interrupted(trx) in lock_wait() can be avoided. We will protect things more consistently with lock_sys.wait_mutex, which will be moved below lock_sys.mutex in the latching order. trx_lock_t::cond: Condition variable for !wait_lock, used with lock_sys.wait_mutex. srv_slot_t: Remove. Replaced by trx_lock_t::cond, lock_grant_after_reset(): Merged to to lock_grant(). lock_rec_get_index_name(): Remove. lock_sys_t: Introduce wait_pending, wait_count, wait_time, wait_time_max that are protected by wait_mutex. trx_lock_t::que_state: Remove. que_thr_state_t: Remove QUE_THR_COMMAND_WAIT, QUE_THR_LOCK_WAIT. que_thr_t: Remove is_active, start_running(), stop_no_error(). que_fork_t::n_active_thrs, trx_lock_t::n_active_thrs: Remove. |
