René Cannaò	b2e3ae4222	Splitting MySQL_Session::handler() ... To make it easier to read, MySQL_Session::handler() was split into multiple functions	6 years ago
René Cannaò	fdff65daea	Implementation of max_transaction_idle_time ...

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	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

René Cannaò	c967bc179b	Several improvements to SQLite3 Server module: ... - ability to handle transactions - in OK packets and resultsets, SERVER_STATUS_IN_TRANS flag is set if a transaction is running - a persistent database file in datadir is used instead of in-memory database - database file uses WAL (Write-Ahead Logging) - WAL journal size is set to 64MB - monitor user can always login to SQLite3 Server - in case of database lock within a transaction, an error is immediately returned to client	6 years ago

René Cannaò	aaf83eec78	Finalizing the support for more session variables ... Initial support for `SET SESSION TRANSACTION READ ONLY` or `READ WRITE`. 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. Several `handler_again___verify_backend_*` functions are disabled if `locked_on_hostgroup` is enabled.	7 years ago

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. Attempting to route traffic while a connection is linked to a specific backend connection will trigger an error to be returned to the client	7 years ago

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

Added new mysql variable `mysql-show_processlist_extended` that determine the content of `stats_mysql_processlist.extended_info`: - 0 : no info - 1 : JSON format - 2 : JSON format with pretty printing	7 years ago
René Cannaò	9788643f38	Track NO_BACKSLASH_ESCAPES #1738 ... `SERVER_STATUS_NO_BACKSLASH_ESCAPES` is now tracked. `set sql_mode` is executed immediately if client executes `set sql_mode` specifying `NO_BACKSLASH_ESCAPES`. A backend connection with `SERVER_STATUS_NO_BACKSLASH_ESCAPES` enabled has multiplexing immediately disabled.	7 years ago

René Cannaò	df606f2c70	Added mysql variable reset_connection_algorithm ... Variable reset_connection_algorithm could either be: 1 = algorithm used up too version 1.4 2 = algorithm new since ProxySQL 2.0 (now default) When reset_connection_algorithm = 2 , MySQL_Thread itself tries to reset connections instead of relying on connections purger HGCU_thread_run()	8 years ago

René Cannaò	d04ee3d385	Remove all references to PS handling before 1.4 ... Handling of prepared statements changed a lot in 1.4 , as a lot of code was rewritten. Old code was still present, and was possible to toggle it on and off based on PROXYSQL_STMT_V14 . Because only the new code is maintained, all references to old code are now removed, including PROXYSQL_STMT_V14	8 years ago
René Cannaò	0f4df84167	Fix bug #1194 ... 3 server errors were retried only once, and then destroying the client connection instead of returning error: * case 1290: // read-only * case 1047: // WSREP has not yet prepared node for application use * case 1053: // Server shutdown in progress This fix should also improve the handling of graceful shutdown (error 1053)	9 years ago
