The bug allow multiple executing transactions working with non-transactional to interfere with each others by interleaving the events of different trans- actions. Bug is fixed by writing non-transactional events to the transaction cache and flushing the cache to the binary log at statement commit. To mimic the behavior of normal statement-based replication, we flush the transaction cache in row- based mode when there is no committed statements in the transaction cache, which means we are committing the first one. This means that it will be written to the binary log as a "mini-transaction" with just the rows for the statement. Note that the changes here does not take effect when building the server with HAVE_TRANSACTIONS set to false, but it is not clear if this was possible before this patch either. For row-based logging, we also have that when AUTOCOMMIT=1, the code now always generates a BEGIN/COMMIT pair for single statements, or BEGIN/ROLLBACK pair in the case of non-transactional changes in a statement that was rolled back. Note that for the case where changes to a non-transactional table causes a rollback due to error, the statement will now be logged with a BEGIN/ROLLBACK pair, even though some changes has been committed to the non-transactional table.
