René Cannaò	4bfe3e5878	Added mysql-monitor_replication_lag_group_by_host ... If variable mysql-monitor_replication_lag_group_by_host=false: (default) Monitor will perform 1 replication lag check per server per hostgroup. If variable mysql-monitor_replication_lag_group_by_host=true: Monitor will perform 1 replication lag check per server. This variable need to be set only in setups in which the same server is configured in many hostgroups, thus reducing the number of checks	4 years ago
René Cannaò	9abb82c2a4	Fixed various bugs detected using valgrind ... * uninitialized variables variables.read_only in Clickhouse * generate_proxysql_internal_session_json() may try to access variables not set This commit also prevents watchdog to restart ProxySQL if running under valgrind.

René Cannaò	2ba9c401f1	Bug fixes in the new implementation of tracking mysql variables ... Better parsing of SET SQL_LOG_BIN . SQL_LOG_BIN is now managed by the same functions that handle boolean variables instead of the now deprecated MySQL_Session::handler_WCD_SS_MCQ_qpo_Parse_SQL_LOG_BIN() For naming convention, enum value SQL_LOG_BIN was renamed to SQL_SQL_LOG_BIN In MySQL_Thread we also deprecated match_regexes[0] , previously used to parse `set sql_log_bin`. Functions Variable::fill_server_internal_session() and Variable::fill_client_internal_session() seems to handle sql_log_bin as a special value. This exception was removed. Fixed a bug in MySQL_Session::generate_proxysql_internal_session_json() where when backend variables needed to be generated, fill_client_internal_session() was incorrectly called instead of fill_server_internal_session() , leading to incorrect values reported by `PROXYSQL INTERNAL SESSION`	4 years ago

René Cannaò	c4fce91fc5	Change default value of mysql-session_idle_ms from 1000 to 1 ... Not only the default value is change from 1000 to 1 , but it also perform an upgrade from earlier release. If during bootstrap a value of 1000 is found, it is automatically changed to 1 and a warning is generated. This release also prevents the value 1000 to be a valid one during bootstrap. This means that it is still possible to set the value to 1000 and to have a running proxysql instance with value 1000 , but during bootstrap it will be switched to 1. If you really want to set mysql-session_idle_ms close to 1000 , it is recommended to set it to a closer value like 999 or 1001	5 years ago

René Cannaò	33d8db02a6	Change the mapping logic for SESSION_TRACK_GTIDS ... Changing the mapping logic in SESSION_TRACK_GTIDS in frontend and backend connections. Up to now, frontend and backend `SESSION_TRACK_GTIDSs match. This is now changed: * backend connections are by default set to `mysql-default_session_track_gtids` * if `mysql-default_session_track_gtids=OFF` (the default) , `session_track_gtids` is not changed on backend * if the client asks for `session_track_gtids=OFF` , proxysql ignores it (it just acknowledge it) * if the client asks for `session_track_gtids=OWN_GTID` , proxysql will apply it * if the client asks for `session_track_gtids=ALL_GTIDS` , proxysql will switch to OWN_GTID and generate a warning * if the backend doesn't support `session_track_gtids` (for example in MySQL 5.5 and MySQL 5.6), proxysql won't apply it. It knows checking server capabilities This commit also deprecates function `MySQL_Session::handler_again___verify_backend__generic_variable()` ProxySQL is now also able to know when proxysql binlog reader is perhaps in use tracking all gtid_port in mysql_servers. This feature in future will be used to deprecate `mysql-default_session_track_gtids`	6 years ago
