# TEST test032
# TEST DB_GET_BOTH, DB_GET_BOTH_RANGE
# TEST
# TEST Use the first 10,000 entries from the dictionary. Insert each with
# TEST self as key and "ndups" duplicates. For the data field, prepend the
# TEST letters of the alphabet in a random order so we force the duplicate
# TEST sorting code to do something. By setting ndups large, we can make
# TEST this an off-page test.
# TEST
# TEST Test the DB_GET_BOTH functionality by retrieving each dup in the file
# TEST explicitly. Test the DB_GET_BOTH_RANGE functionality by retrieving
# TEST the unique key prefix (cursor only). Finally test the failure case.
