- # DB Test 87: Test of cursor stability on duplicate pages w/aborts.
- # Does the following:
- # a. Initialize things by DB->putting ndups dups and
- # setting a reference cursor to point to each.
- # b. c_put ndups dups (and correspondingly expanding
- # the set of reference cursors) after the last one, making sure
- # after each step that all the reference cursors still point to
- # the right item.
- # c. Ditto, but before the first one.
- # d. Ditto, but after each one in sequence first to last.
- # e. Ditto, but after each one in sequence from last to first.
- # occur relative to the new datum)
- # f. Ditto for the two sequence tests, only doing a
- # DBC->c_put(DB_CURRENT) of a larger datum instead of adding a
- # new one.
