René Cannaò	f3c604eb84	Implemented mysql_hostgroup_attributes.multiplex ... If mysql_hostgroup_attributes.multiplex: - 0 : multiplexing is always disabled - 1 : multiplexing is enabled for the hostgroup, but other criteria can disable multiplexing (transaction, temp tables, query rules, etc)	3 years ago
Rahim Kanji	dbfb99ce71	* Added hostname and ip information in mysql_connection ... * Added multiple IP support with load balancing (Round Robin Scheduling) * Added DNS resolver request max queue size * Added AI_ADDRCONFIG flag * Exception handling	3 years ago
Javier Jaramago Fernández	bcc6532d66	Modify previous impl for 'auto_increment_delay_multiplex_timeout_ms' and fix 'connection_delay_multiplex_ms' ... This commit contains an implementation rework and a fix: - Impl for 'auto_increment_delay_multiplex_timeout_ms' has been reworked in favor of reusing 'wait_until' to share logic with previous 'connection_delay_multiplex_ms' variable. - Fix previous 'connection_delay_multiplex_ms' behavior preventing connection retaining when traffic unrelated to target hostgroup is being received by the session.	4 years ago
Javier Jaramago Fernández	a67db17709	Fix current 'auto_increment_delay_multiplex_timeout_ms' behavior #3923	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

Javier Jaramago Fernández	4b81e21d57	Added comments, simplified 'stmt->result.data' assignment and minor cleanup for 'process_rows_in_ASYNC_STMT_EXECUTE_STORE_RESULT_CONT'	5 years ago
René Cannaò	7921e130d2	Third commit to buffer resultsets in Prepared Statements ... * MySQL_ResultSet() stores a pointer to the PS * MySQL_ResultSet::init_with_stmt() doesn't need anymore the pointer to the PS Furthermore, it isn't anymore an "init" but an end (we will rename it) * Added MySQL_ResultSet::add_row(MYSQL_ROWS *rows) for PS only * MySQL_Protocol::generate_pkt_row3() accepts an optional row length. If passed, it will know the length of the row without computing it * MyRS initialized during ASYNC_STMT_EXECUTE_STORE_RESULT_START * Implemented throttling during ASYNC_STMT_EXECUTE_STORE_RESULT_START * MySQL_Connection::process_rows_in_ASYNC_STMT_EXECUTE_STORE_RESULT_CONT() always generates a heartbeat. For now unnecessary, and we will better tune it later * test_ps_async-t.cpp tunes mysql-threshold_resultset_size to trigger buffering More testing is required	5 years ago
René Cannaò	5c0a732d8a	Second commit to buffer resultsets in Prepared Statements ... So far this seems to work, although it is dropping most of the rows. The rows are lost intentionally up to this commit.	5 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
