+#  BUG#39753: Replication failure on MIXED + bit + myisam + no PK
+#
+# Description
+# -----------
+#  Simple statements against a bit column cause failure in mixed-mode
+#  replication.
+#
+#  Implementation is as follows:
+#     i) A table with two bit fields is created. One of them is a key.
+#    ii) A record is inserted without specifying the key value.
+#   iii) The record is deleted using a where clause that matches it.
+#    iv) repeat i-iii) for bit key that has different size, generating
+#        different extra bits values 
+#     v) The slave is synchronized with master 
+#    vi) The table is dropped on master and the slave is re-synchronized
+#        with master.
+#
+#  Step v) made the bug evident before the patch, as the slave would 
+#  fail to find the correspondent row in its database (although it did
+#  the insert in step ii) ).
+#
+# Obs
+# --- 
+#  This test is based on the "how to repeat" section from the bug report.
