# TEST test087
# TEST Test of cursor stability when converting to and modifying
# TEST off-page duplicate pages with subtransaction aborts. [#2373]
# TEST
# TEST Does the following:
# TEST a. Initialize things by DB->putting ndups dups and
# TEST setting a reference cursor to point to each. Do each put twice,
# TEST first aborting, then committing, so we're sure to abort the move
# TEST to off-page dups at some point.
# TEST b. c_put ndups dups (and correspondingly expanding
# TEST the set of reference cursors) after the last one, making sure
# TEST after each step that all the reference cursors still point to
# TEST the right item.
# TEST c. Ditto, but before the first one.
# TEST d. Ditto, but after each one in sequence first to last.
# TEST e. Ditto, but after each one in sequence from last to first.
# TEST occur relative to the new datum)
# TEST f. Ditto for the two sequence tests, only doing a
# TEST DBC->c_put(DB_CURRENT) of a larger datum instead of adding a
# TEST new one.
