# BUG#59338 Inconsistency in binlog for statements that don't change any rows STATEMENT SBR
|
|
# In SBR, if a statement does not fail, it is always written to the binary log,
|
|
# regardless if rows are changed or not. If there is a failure, a statement is
|
|
# only written to the binary log if a non-transactional (.e.g. MyIsam) engine
|
|
# is updated. INSERT ON DUPLICATE KEY UPDATE was not following the rule above
|
|
# and was not written to the binary log, if then engine was Innodb.
|
|
#
|
|
# In this test case, we check if INSERT ON DUPLICATE KEY UPDATE that does not
|
|
# change anything is still written to the binary log.
|
|
|
|
# Prepare environment

# An insert duplicate that does not update anything must be written to the binary
|
|
# log in SBR and MIXED modes. We check this property by summing a before and after
|
|
# the update and comparing the binlog positions. The sum should be the same at both
|
|
# points and the statement should be in the binary log.
