Summary: In D1515, I introduced some excessively-complicated semantics for detecting connections that are lost while transactional. These semantics cause us to reenter establishConnection() and establish twice as many connections as we need in the common case. We don't need a hook there at all -- it's sufficient to throw the exception rather than retrying the query when we encounter it. This doesn't have reentrancy problems. Test Plan: - Added some encapsulation-violating hooks and a unit test for them - Verified we no longer double-connect.
