+# 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.
+
+#
+# This was introduced due to the following bug on windows:
+# BUG#43264 Test rpl_trigger is failing randomly w/ use of copy_file in 5.0 
+# Unfortunately, it is not possible to share a solution as 5.0 has the following issues:
+#   1 - Inability to restart a server in the middle of a test case.
+#   2 - Neither the index or the binlogs are re-opened when the slave is stopped and
+#   restarted.
