If we're doing a 7.2.2, it may be worth it. I think that part of the patch
(minus concerns about variables possibly not being reset, etc) is
reasonably safe (and that part could be reasonably looked at again
quickly) and did have some limited testing due to a couple of people
getting the patch back during 7.2's development.
As a related side note. The other part of the original patch (the NOT
EXISTS in the upd/del no action trigger) was rejected. For match
full and match unspecified the same result can be reached by doing another
query which may be better than the subquery. Do you think that'd be
better? I'd like to get the other side of this bug fixed so that at least
the no action cases work reasonably correctly. :)
