Convert events worker database to async/await. (#8071) 2020-08-18 16:20:49 -04:00

Fix recursion error when fetching auth chain over federation (#7817)
When fetching the state of a room over federation we receive the event
IDs of the state and auth chain. We then fetch those events that we
don't already have.

However, we used a function that recursively fetched any missing auth
events for the fetched events, which can lead to a lot of recursion if
the server is missing most of the auth chain. This work is entirely
pointless because would have queued up the missing events in the auth
chain to be fetched already.

Let's just diable the recursion, since it only gets called from one
place anyway.

Pass room version object into event_auth.check and check_redaction (#6788)
These are easier to work with than the strings and we normally have one around.

This fixes `FederationHander._persist_auth_tree` which was passing a
RoomVersion object into event_auth.check instead of a string.

Richard van der Hoff 8afddf7afe Fix error handling for missing auth_event
When we were authorizing an event, if there was no `m.room.create` in its
auth_events, we would raise a SynapseError with a cryptic message, which then
meant that we would bail out of processing any incoming events, rather than
storing a rejection for the faulty event and moving on.

We should treat the absent event the same as any other auth failure, by
raising an AuthError, so that the event is marked as rejected.

Make it so that, before there is a power-levels event in the room, you need a
power level of at least 50 to send state.
