- # Insert each with self as key and "ndups" duplicates
- # For the data field, prepend the letters of the alphabet
- # in a random order so that we force the duplicate sorting
- # code to do something.
- # By setting ndups large, we can make this an off-page test
- # After all are entered; test the DB_GET_BOTH functionality
- # first by retrieving each dup in the file explicitly. Then
- # remove each duplicate and try DB_GET_BOTH again.
