Testing
-------
Note that this removes a defensive branch wherein we checked for inbound config
references before attempting to delete. With this change, we proactively
delete and count on foreign key constraints to prevent deletion of rows that
are still referenced. I propose we adopt this as our pattern for handling
shared references, as it seems to be the most sane approach available.
A gotcha with this case is that i do not believe mybatis provides a
vendor-neutral approach to identify a consistency violation, and the best
signal is a generic `PersistenceException`. This is unfortunate since we can't
distinguish between a hopeless query with invalid syntax, a network
disconnection, or the anticipated case of a consistency violation.
Thanks,
Bill Farner
