# BUG#16266: Definer is not fully qualified error during replication.
#
# The idea of this test is to emulate replication of a trigger from the old
# master (master w/o "DEFINER in triggers" support) to the new slave and check
# that:
#   1. the trigger on the slave will be replicated w/o errors;
#   2. the trigger on the slave will be non-SUID (will have no DEFINER);
#   3. the trigger can be activated later on the slave w/o errors.
#
# In order to emulate this kind of replication, we make the slave playing the binlog,
# recorded by 5.0.16 master. This binlog contains the following statements:
#   CREATE TABLE t1(c INT);
#   CREATE TABLE t2(s CHAR(200));
#   CREATE TRIGGER trg1 AFTER INSERT ON t1
#     FOR EACH ROW
#       INSERT INTO t2 VALUES(CURRENT_USER());
#   INSERT INTO t1 VALUES(1);
#

# 1. Check that the trigger's replication is succeeded.
