René Cannaò	99b4dd4bbd	Merge pull request #2243 from sysown/v2.0.7.2 ... V2.0.7.2	7 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	7b3757a273	Remember if the current connection has an unknown transaction status ... The fix for bug #1038 was to not return a connection to the connection pool if it has an error. Although this is correct, it also has the side effect that connections coming from connection pool and failing during the first query because the connection was already broken, would be considered as possibly to run a transaction. That is incorrect. Now at connection level it is tracked if the transaction status is known or not.	8 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
