+# ==== Purpose ====
+#
+# Check that DMLs are allowed on temporary tables, when server is in read only
+# mode and binary log is enabled with binlog-format being stmt/mixed mode.
+#
+# ==== Implementation ====
+#
+# Start the server with binary log being enabled. Mark the server as read only.
+# Create a non-SUPER user and let the user to create a temporary table and
+# perform DML operations on that temporary table. DMLs should not be blocked
+# with a 'server read-only mode' error.
+#

+# TABLES
+# Bug#14294223: CHANGES NOT ALLOWED TO TEMPORARY TABLES ON READ-ONLY SERVERS
