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.
