# TEST test031

# TEST Duplicate sorting functionality
|

# TEST Make sure DB_NODUPDATA works.
|

# TEST
|
||||
# TEST Use the first 10,000 entries from the dictionary.
|
||||
# TEST Insert each with self as key and "ndups" duplicates
|
||||
# TEST For the data field, prepend random five-char strings (see test032)
|
||||
# TEST that we force the duplicate sorting code to do something.
|
||||
# TEST Along the way, test that we cannot insert duplicate duplicates
|
||||
# TEST using DB_NODUPDATA.
|
||||
# TEST
|
||||
# TEST By setting ndups large, we can make this an off-page test
|
||||
# TEST After all are entered, retrieve all; verify output.
|
||||
# TEST Close file, reopen, do retrieve and re-verify.
|
||||
# TEST This does not work for recno
