Author	SHA1	Message	Date
René Cannaò	dd017bbaf5	Fix a bug related to SET autocommit=1 filtered ... If SET autocommit=1 was used to terminate a transaction, proxysql wasn't executing it and the transaction was staying open.	6 years ago
René Cannaò	47d3420662	Change default of exit_after_SetParse ... In handler___status_WAITING_CLIENT_DATA___STATE_SLEEP___MYSQL_COM_QUERY_qpo() Changing the default of exit_after_SetParse from false to true. If a variable isn't parsed or it needs to be forwarded, exit_after_SetParse is set to false	6 years ago
René Cannaò	848ddb2177	Added variable mysql-connect_timeout_client ... This also fix bug #1132	6 years ago
Rene Cannao	41b173a83c	Fixing a lot of compiler warnings	6 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

Arthur Schreiber	8ed63e8404	Reset data stream status after switching users. ... When a backend connection is reused for a different user, the data stream status is set to `STATE_MARIADB_QUERY`, but was not set back to `STATE_MARIADB_GENERIC` once the user was switched successfully. This caused additional connection setup (like executing `init_connect`) to be skipped on the first query after switching users. If another query using the the same user was executed, this new query would end up performing this additional connection setup. By setting the data stream status back to `STATE_MARIADB_GENERIC`, we can ensure connection setup happens correctly after switching users.	6 years ago
Arthur Schreiber	32d6ba65c0	Actually set `session_track_gtids` on new backends. ... When a new backend connection was selected, the `session_track_gtids` config variable would be marked as set, but was never actually set on the backed connection.	6 years ago

René Cannaò	7b021e027a	Do not cache routing metadata for COM_STMT_EXECUTE ... From 1.3.0 till 2.0.x , when COM_STMT_PREPARE is executed and Query Processor is executed, metadata are stored in MySQL_STMT_Global_info(). These metadata include routing information. Is a prepared statement is prepared on a specific hostgroup, it will always be executed on the same hostgroup. This causes negative consequences, like the one reported in issue #2691 . This commit: * remove hostgroup_id from MySQL_STMT_Global_info() and other metadata * Query Processor is called also during COM_STMT_EXECUTE * removes hostgroup from table stats_mysql_prepared_statements_info * Query Processor do not perform any query rewrite ruding COM_STMT_EXECUTE	6 years ago
