+# 
+# Test for bug#18437 "Wrong values inserted with a before update
+# trigger on NDB table". SQL-layer didn't properly inform handler
+# about fields which were read and set in triggers. In some cases 
+# this resulted in incorrect (garbage) values of OLD variables and
+# lost changes to NEW variables.
+# You can find similar tests for ON INSERT triggers in federated.test
+# since this engine so far is the only engine in MySQL which cares
+# about field mark-up during handler::write_row() operation.
