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
