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 and INSERT IGNORE were not following the rule above and were not written to the binary log, if then engine was Innodb.

# Testcase for BUG#6287 "Slave skips auto_increment values in Replication with InnoDB"
|
|
# The bug was that if on master, INSERT IGNORE ignored some
|
|
# rows, and the table was InnoDB with auto_inc column, then on slave
|
|
# some rows received an auto_inc bigger than on master.
|
|
# Slave needs to be started with --innodb to store table in InnoDB.
|
|
# Same test for MyISAM (which had no bug).
