BUG#44581 Slave stops when transaction with non-transactional table gets lock wait

Browse Source 
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.
            
Unfortunately, statements that fail due to concurrency issues (e.g. deadlocks,
timeouts) are logged in the same way causing the slave to stop as the statements
are applied sequentially by the SQL Thread. To fix this bug, we automatically
ignore concurrency failures on the slave. Specifically, the following failures
are ignored: ER_LOCK_WAIT_TIMEOUT, ER_LOCK_DEADLOCK and ER_XA_RBDEADLOCK.

#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.
