slave_list was used to provide data for SHOW SLAVE HOSTS and Slaves_connected status variable. Introduced binlog_dump_thread_count which is exposed via Slaves_connected (replaces slave_list.records). Store Slave_info on THD and access it by iterating server_threads (replaces slave_list). Added: THD::slave_info binlog_dump_thread_count show_slave_hosts_callback() Removed: slave_list SLAVE_LIST_CHUNK SLAVE_ERRMSG_SIZE slave_list_key() slave_info_free() init_slave_list() end_slave_list() all_slave_list_mutexes init_all_slave_list_mutexes() key_LOCK_slave_list LOCK_slave_list Moved: SLAVE_INFO -> Slave_info register_slave() -> THD::register_slave() unregister_slave() -> THD::unregister_slave() Also removed redundant end_slave() from close_connections(): it is called again soon afterwards by clean_up(). Pre-requisite for clean MDEV-18450 solution.
