In cases where an actor's transport server task (by default handling new TCP connections) terminates early but does not de-register from the pertaining registry (aka the registrar) actor's address table, the trying-to-connect client actor will get a connection error on that address. In the case where client handles a (local) `OSError` (meaning the target actor address is likely being contacted over `localhost`) exception, make a further call to the registrar to delete the stale entry and `yield None` gracefully indicating to calling code that no `Portal` can be delivered to the target address. This issue was originally discovered in `piker` where the `emsd` (clearing engine) actor would sometimes crash on rapid client re-connects and then leave a `pikerd` stale entry. With this fix new clients will attempt connect via an endpoint which will re-spawn the `emsd` when a `None` portal is delivered (via `maybe_spawn_em()`). |
