which Heikki fixed in 4.1.8 and 4.0.23. I verified that without Heikki's patch the test fails (7 gets inserted). Test added to 4.1 because in testsuite of 4.0 it's impossible to start slave with 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).
