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.

#BUG#44581 Slave stops when transaction with non-transactional table gets
#lock wait timeout
#
# In STMT and MIXED modes, a statement that changes both non-transactional and
# transactional tables must be written to the binary log whenever there are
# changes to non-transactional tables. This means that the statement gets into
# the # binary log even when the changes to the transactional tables fail. In
# particular, in the presence of a failure such statement is annotated with the
# error number and wrapped in a begin/rollback. On the slave, while applying
# the statement, it is expected the same failure and the rollback prevents the
# transactional changes to be persisted.
# This test aims to verify if a statement that updates both transactional and
# non-transacitonal tables and fails due to concurrency problems is correctly
# processed by the slave in the sense that the statements get into the binary
# log, the error is ignored and only the non-transactional tables are changed.
