They maintain a connection to their master server, read log events from the master as they arrive, and queues them into a single, shared relay log file. A Master_info represents each of these threads. SQL Thread - One of these threads is started and reads from the relay log file, executing each event. A Relay_log_info represents this thread. Buffering in the relay log file makes it unnecessary to reread events from a master server across a slave restart. It also decouples the slave from the master where long-running updates and event logging are concerned--ie it can continue to log new events while a slow query executes on the slave. *****************************************************************************/ /* MUTEXES in replication: LOCK_active_mi: [note: this was originally meant for multimaster, to switch from a master to another, to protect active_mi] It is used to SERIALIZE ALL administrative commands of replication: START SLAVE, STOP SLAVE, CHANGE MASTER, RESET SLAVE, end_slave() (when mysqld stops) [init_slave() does not need it it's called early]. Any of these commands holds the mutex from the start till the end. This thus protects us against a handful of deadlocks (consider start_slave_thread() which, when starting the I/O thread, releases mi->run_lock, keeps rli->run_lock, and tries to re-acquire mi->run_lock). Currently active_mi never moves (it's created at startup and deleted at shutdown, and not changed: it always points to the same Master_info struct), because we don't have multimaster. So for the moment, mi does not move, and mi->rli does not either. In Master_info: run_lock, data_lock run_lock protects all information about the run state: slave_running, thd and the existence of the I/O thread (to stop/start it, you need this mutex). data_lock protects some moving members of the struct: counters (log name, position) and relay log (MYSQL_BIN_LOG object). In Relay_log_info: run_lock, data_lock see Master_info However, note that run_lock does not protect Relay_log_info.run_state; that is protected by data_lock. Order of acquisition: if you want to have LOCK_active_mi and a run_lock, you must acquire LOCK_active_mi first. In MYSQL_BIN_LOG: LOCK_log, LOCK_index of the binlog and the relay log LOCK_log: when you write to it. LOCK_index: when you create/delete a binlog (so that you have to update the .index file). */ extern ulong master_retry_count; extern MY_BITMAP slave_error_mask; extern char slave_skip_error_names[]; extern bool use_slave_mask; extern char slave_transaction_retry_error_names[]; extern uint *slave_transaction_retry_errors; extern uint slave_transaction_retry_error_length; extern char *slave_load_tmpdir; extern char *master_info_file; extern MYSQL_PLUGIN_IMPORT char *relay_log_info_file; extern char *opt_relay_logname, *opt_relaylog_index_name; extern my_bool opt_skip_slave_start, opt_reckless_slave; extern my_bool opt_log_slave_updates; extern char *opt_slave_skip_errors; extern char *opt_slave_transaction_retry_errors; extern my_bool opt_replicate_annotate_row_events; extern ulonglong relay_log_space_limit; extern ulonglong opt_read_binlog_speed_limit; extern ulonglong slave_skipped_errors; extern const char *relay_log_index; extern const char *relay_log_basename; /* 4 possible values for Master_info::slave_running and Relay_log_info::slave_running.
