René Cannaò	622b748fdf	Switching autocommit from 0 to 1 drops SAVEPOINTs ... Another edge case due to MySQL bug https://bugs.mysql.com/bug.php?id=107875 related to autocommit=0 and SAVEPOINT	4 years ago
René Cannaò	f7d8824379	Trying to work around MySQL bug 107875 ... Because of MySQL bug https://bugs.mysql.com/bug.php?id=107875 , autocommit=0 can "create a transaction" even if SERVER_STATUS_IN_TRANS is not set. This means that a SAVEPOINT can be created in a "transaction" created with autocommit=0 but without SERVER_STATUS_IN_TRANS . This commit takes also care of scenarios when autocommit=0 was switched back to autocommit=1 when a SELECT was executed while variable mysql-enforce_autocommit_on_reads was false. MySQL_Session::NumActiveTransactions() now accepts a flag to check for savepoints.	4 years ago
René Cannaò	61b32de42f	Solve bug #3749 and improve testing ... In MySQL_Connection::IsActiveTransaction: in the past we were incorrectly checking STATUS_MYSQL_CONNECTION_HAS_SAVEPOINT and returning true in case there were any savepoint. Although flag STATUS_MYSQL_CONNECTION_HAS_SAVEPOINT was not reset in case of no transaction, thus the check was incorrect. We can ignore STATUS_MYSQL_CONNECTION_HAS_SAVEPOINT for multiplexing purpose in IsActiveTransaction() because it is also checked in MultiplexDisabled()	4 years ago
