# 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).
-- source include/have_innodb.inc
-- source include/master-slave.inc
CREATE TABLE t1 (
a int unsigned not null auto_increment primary key,
b int unsigned,
unique (b)
) ENGINE=innodb;
CREATE TABLE t2 (
a int unsigned, # to force INSERT SELECT to have a certain order
b int unsigned
) ENGINE=innodb;
INSERT INTO t1 VALUES (NULL, 1);
INSERT INTO t1 VALUES (NULL, 2);
INSERT INTO t1 VALUES (NULL, 3);
INSERT INTO t1 VALUES (NULL, 4);
# An alternation of values which will conflict in t1 and will not.

# Now do the same for MyISAM
