Brice Figureau	fccef7f64e	Parse multiple variable (simple) SET commands ... The current parser for SET in MySQL_Session is not able to parse multiple variables SET commands like: SET sql_mode='TRADITIONAL', NAMES utf8 COLLATE unicode_ci This patch introduces a simple regex based parser for all variation of simple variables. This is not a generic SET parser, though.	8 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	2bb322db6f	Several fixed in Prepared statements ... * is STMT_PREPARE failed when there is a previous status (maybe STMT_EXECUTE) disconnect the client immediately.
