René Cannaò	5f0b68d004	Upgrading MariaDB Connector C to 2.3.1 ... ProxySQL used a patched version of MariaDB Connector C 2.1.0 (aka libmariadbclient). That version was patched to fix several bugs. Although, version 2.1.0 seems to be quite broken in handling Prepared Statements, so now MariaDB Connector C was upgraded to version 2.3.1 . Since this is a key compoenent in ProxySQL, several tests need to be performed because of this major change.	10 years ago

René Cannaò	f40affc361	Removed variable mysql-bug_mdev_8338 ... It seems that bug https://mariadb.atlassian.net/browse/MDEV-8338 is so severe that bypassing it from ProxySQL is not that easy.

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.
