binlog
The fix for BUG 43929 introduced a regression issue. In a nutshell, when a
statement that changes a non-transactional table fails, it is written to the
binary log with the error code appended. Unfortunately, after BUG 43929, this
failure was flushing the transactional chace causing mismatch between execution
and logging histories. To fix this issue, we avoid flushing the transactional
cache when a commit or rollback is not issued.

#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.
