Eric Eastwood 0f971ca68e Update `get_pdu` to return the original, pristine `EventBase` (#13320) ... Update `get_pdu` to return the untouched, pristine `EventBase` as it was originally seen over federation (no metadata added). Previously, we returned the same `event` reference that we stored in the cache which downstream code modified in place and added metadata like setting it as an `outlier` and essentially poisoned our cache. Now we always return a copy of the `event` so the original can stay pristine in our cache and re-used for the next cache call. Split out from https://github.com/matrix-org/synapse/pull/13205 As discussed at: - https://github.com/matrix-org/synapse/pull/13205#discussion_r918365746 - https://github.com/matrix-org/synapse/pull/13205#discussion_r918366125 Related to https://github.com/matrix-org/synapse/issues/12584. This PR doesn't fix that issue because it hits [`get_event` which exists from the local database before it tries to `get_pdu`](7864f33e28/synapse/federation/federation_client.py (L581-L594)).		2022-07-20 15:58:51 -05:00
