#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.
