Javier Sánchez Parra	1e00e1f021	Assign hostgroup from previous COM_QUERY ... The destination hostgroup assigned from previous COM_QUERY commands is the one used to establish the fast_forward connection. As a result, multiple binlog clients can consume binlog events from different MySQL hostgroups using the same username.	3 years ago

René Cannaò	622b748fdf	Switching autocommit from 0 to 1 drops SAVEPOINTs ... Another edge case due to MySQL bug https://bugs.mysql.com/bug.php?id=107875 related to autocommit=0 and SAVEPOINT	4 years ago
René Cannaò	f7d8824379	Trying to work around MySQL bug 107875 ... Because of MySQL bug https://bugs.mysql.com/bug.php?id=107875 , autocommit=0 can "create a transaction" even if SERVER_STATUS_IN_TRANS is not set. This means that a SAVEPOINT can be created in a "transaction" created with autocommit=0 but without SERVER_STATUS_IN_TRANS . This commit takes also care of scenarios when autocommit=0 was switched back to autocommit=1 when a SELECT was executed while variable mysql-enforce_autocommit_on_reads was false. MySQL_Session::NumActiveTransactions() now accepts a flag to check for savepoints.	4 years ago

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	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

Extended `SET` parser to support also `SET SESSION TRANSACTION`. Hostgroup Manager doesn't kill backend connections in case of error 1231. `autocommit` is set at session level but also on MySQL client connection. Added several debugging entries.

René Cannaò	8c4b70a557	Added capability to lock hostgroup ... This should fix a lot of issues related to failed parsing of SET statement. This and the two 2 previous commits introduce several status variables, and a new configuration variable: mysql-set_query_lock_on_hostgroup Possible values for mysql-set_query_lock_on_hostgroup: - 0 : legacy behavior , before 2.0.5 - 1 : (default) . SET statements that cannot be parsed correctly disable both multiplexing AND routing.

René Cannaò	0831740e45	Several enhancements on Query logger ... Enhancements: - added metrics rows_affected and rows_sent - added global variable mysql-eventslog_default_log : if 1 , logging is enabled for every query unless explicitly disabled in mysql_query_rules.log . Default is 0 - added global variable mysql-eventslog_format : default is 1 (legacy format). A value of 2 enables logging in JSON format. Issue #871 Changing value at runtime causes the current file to be closed and a new one created - fixed logging for prepared statements: till 2.0.5 only some percentage of prepared statements was correctly logged Extended tables stats_mysql_query_digest and stats_mysql_query_digest_reset to also include sum_rows_affected and sum_rows_sent Extended `eventslog_reader_sample.cpp` to support the new enhancements	7 years ago
