|
# XXX
|
|
# Other tests that cover more specific variants of the same issue
|
|
# are in the access method tests for now. This is probably wrong; we
|
|
# put this one here because they're closely based on and intertwined
|
|
# with other, non-transactional cursor stability tests that are among
|
|
# the access method tests, and because we need at least one test to
|
|
# fit under recd and keep logtrack from complaining. We'll sort out the mess
|
|
# later; the important thing, for now, is that everything that needs to gets
|
|
# tested. (This really shouldn't be under recd at all, since it doesn't
|
|
# run recovery!)
