### SETUP

  eval drop table if exists t1$rnd;
  connection slave;
  eval drop table if exists t2$rnd,t3$rnd;
--enable_warnings

  connection master;
  eval create table t1$rnd (f1 int)  /* 2 replicate */;

  let $i=$max_rows;

### Test

  eval SELECT * from t1$rnd /* must be f1 $max_rows, 1 - $max_rows 2 - $max_rows ... -1 */;

### CLEANUP

#
# 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.

# Stop the slave.

connection slave;
STOP SLAVE;

# Replace master's binlog.

connection master;
FLUSH LOGS;
exec cp $MYSQL_TEST_DIR/std_data/bug16266.000001 $MYSQLTEST_VARDIR/log/master-bin.000001;

# Make the slave to replay the new binlog.

# Check that the replication succeeded.

# 2. Check that the trigger is non-SUID on the slave;
# 3. Check that the trigger can be activated on the slave.

INSERT INTO t1 VALUES(2);

SELECT * FROM t1;
SELECT * FROM t2;

# That's all, cleanup.
