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

René Cannaò	2e276f06f4	Second commit to implement mirroring 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 Add new variable MySQL_Session::mirror (false by default) Add new struct MySQL_Session::mirrorPkt (false by default) These functions return immediately if this is a mirror session: * MySQL_Protocol::generate_pkt_EOF() * MySQL_Protocol::generate_pkt_ERR() * MySQL_Protocol::generate_pkt_OK() * MySQL_Protocol::generate_pkt_column_count() * MySQL_Protocol::generate_pkt_field() * MySQL_Protocol::generate_pkt_row3() MySQL_ResultSet::MySQL_ResultSet() exits almost immediately if this is a mirror session Most of the code of these functions is not executed if this is a mirror session: * MySQL_ResultSet::add_eof() * MySQL_ResultSet::get_resultset() In MySQL_Session::writeout() : * `client_myds->write_to_net_poll()` is called only if this is not a mirror session In MySQL_Session::handler(): * if query is a `SELECT` (hardcoded for now) : create a new session and mark it as `mirror=true` duplicate the query and send it to the new session * if `mirror==true` : pretend to read a new query from c`lient_myds` proceed normally (with the only exception that no data can be sent to a client) In MySQL_Thread::process_all_sessions() : * if `mirror==true` and `status==WAITING_CLIENT_DATA` it means the session is "completed" so it get destroyed Limitations: * it currently doesn't support large packets * doesn't support different charset * doesn't support transactions	10 years ago

René Cannaò	cfd0cf32e8	QueryParserArgs is moved into Query_Info This is a further attempt to reduce calls to malloc() QueryParserArgs is no longer a pointer, but a struct inside Query_info	10 years ago
René Cannaò	b5792ad2cb	Disabling the smart handling of transactions #469 Moved some code from MySQL_Session:handler_special_queries() into two new functions: - MySQL_Session::handler_CommitRollback() - MySQL_Session::handler_SetAutocommit() These two new functions are called nowhere: de facto they are disabled	10 years ago
René Cannaò	dd3b7e5a82	Removed any reference to MySQL_Session::pause the variable wasn't in used from long time	10 years ago
René Cannaò	95d2671a4e	Removed a lot of deprecated code	10 years ago
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	10 years ago
René Cannaò	6b05a69e1b	Improving query statistics/information Added MySQL_Session::RequestEnd() to wrap CurrentQuery.end() and other state changes : this to minimize bugs MySQL_Session::RequestEnd() sets query end time instead of Query_Info::end() MySQL_Session::RequestEnd() is called also in case of special queries handled by handler_special_queries()	10 years ago
