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 ... Former max_transaction_time is now renamed to max_transaction_idle_time. mysql-max_transaction_idle_time defines the maximum time a transaction can stay idle. mysql-max_transaction_time defines the maximum time of a transaction since its start.	6 years ago
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

This commit fix the following bug: If some session variables were set by the client before proxysql turned on lock_hostgroup, these variables were not set.

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 ...

Expanded table `mysql_query_rules` to add `mirror_hostgroup` Expanded struct `_Query_Processor_rule_t` and class `Query_Processor_Output` to support `mirror_hostgroup` Added new variable `mirror_hostgroup` in `MySQL_Session` The following logic ensure that a mirror_hostgroup set when processing the query in the original session is preserved when reprocessing the query in the mirror session: * when a new mirror session is *created* `mirror_hostgroup` is set according to the result of Query_Processor * when a mirror session is *executed* , `mirror_hostgroup` is copied into `default_hostgroup` Current limitations: * queries larger than 15MB aren't mirrorred * upgrade from 1.1 is still not possible it will wipe table mysql_query_rules	10 years ago
René Cannaò	c101fad268	First draft on mirroring feature ...

René Cannaò	c3e6fda7a4	Track and handle autocommit (#438) ... - MySQL_Session::handler_special_queries() processes set autocommit from clients - to the client is always returned the autocommit value set in the session - set autocommit is either just acknowledged to the client, or forwarded to the backend based on the status of transactions - unless there are query rules to handle SET AUTOCOMMIT , the statement is forwarded to the first found active transaction: this assumes there is just one transactions. Although multiple transactions are possible, handling multiple transactions at the same time seems a dangerous adventure	11 years ago
René Cannaò	6b05a69e1b	Improving query statistics/information ...
