# Both of the following tests check that comparison of binlog BI
|
|
# against SE record will not fail due to remains from previous values
|
|
# in the SE record (before a given field was set to null).
|
|
#
|
|
# In MIXED mode:
|
|
# - Insert and update are executed as statements
|
|
# - Delete is executed as a row event
|
|
# - Assertion: checks that comparison will not fail because the update
|
|
# statement will clear the record contents for the nulled
|
|
# field. If data was not cleared, some engines may keep
|
|
# the value and return it later as garbage - despite the
|
|
# fact that field is null. This may cause slave to
|
|
# falsely fail in the comparison (memcmp would fail
|
|
# because of "garbage" in record data).
|
|
#
|
|
# In ROW mode:
|
|
# - Insert, update and delete are executed as row events.
|
|
# - Assertion: checks that comparison will not fail because the update
|
|
# rows event will clear the record contents before
|
|
# feeding the new value to the SE. This protects against
|
|
# SEs that do not clear record contents when storing
|
|
# nulled fields. If the engine did not clear the data it
|
|
# would cause slave to falsely fail in the comparison
|
|
# (memcmp would fail because of "garbage" in record
|
|
# data). This scenario is pretty much the same described
|
|
# above in MIXED mode, but checks different execution
|
|
# path in the slave.
