Non-transactional updates that take place inside a transaction present problems for logging because they are visible to other clients before the transaction is committed, and they are not rolled back even if the transaction is rolled back. It is not always possible to log correctly in statement format when both transactional and non-transactional tables are used in the same transaction. In the current patch, we ensure that such scenario is completely safe under the ROW and MIXED modes.
