# bug#31609 Not all RBR slave errors reported as errors
# bug#31552 Replication breaks when deleting rows from out-of-sync table
# without PK
# The default for slave-exec-mode option and server
# variable slave_exec_mode is 'STRICT'.
# When 'STRICT' mode is set, the slave SQL thread will stop whenever
# the row to change is not found. In 'IDEMPOTENT' mode, the SQL thread
# will continue running and apply the row - replace if it's Write_rows event -
# or skip to the next event.
# the previous part of the tests was with IDEMPOTENT slave's mode.
#
# Other than above idempotent errors dealing with foreign keys constraint
