# TEST test054
|

# TEST Cursor maintenance during key/data deletion.
|
||||
# TEST
|
||||
# TEST This test checks for cursor maintenance in the presence of deletes.
|
||||
# TEST There are N different scenarios to tests:
|
||||
# TEST 1. No duplicates. Cursor A deletes a key, do a GET for the key.
|
||||
# TEST 2. No duplicates. Cursor is positioned right before key K, Delete K,
|
||||
# TEST do a next on the cursor.
|
||||
# TEST 3. No duplicates. Cursor is positioned on key K, do a regular delete
|
||||
# TEST of K, do a current get on K.
|
||||
# TEST 4. Repeat 3 but do a next instead of current.
|
||||
# TEST 5. Duplicates. Cursor A is on the first item of a duplicate set, A
|
||||
# TEST does a delete. Then we do a non-cursor get.
|
||||
# TEST 6. Duplicates. Cursor A is in a duplicate set and deletes the item.
|
||||
# TEST do a delete of the entire Key. Test cursor current.
|
||||
# TEST 7. Continue last test and try cursor next.
|
||||
# TEST 8. Duplicates. Cursor A is in a duplicate set and deletes the item.
|
||||
# TEST Cursor B is in the same duplicate set and deletes a different item.
|
||||
# TEST Verify that the cursor is in the right place.
|
||||
# TEST 9. Cursors A and B are in the place in the same duplicate set. A
|
||||
# TEST deletes its item. Do current on B.
|
||||
# TEST 10. Continue 8 and do a next on B.
