From e8d08537394a49f3e66e9cbea3627e3c25818a7d Mon Sep 17 00:00:00 2001 From: Andrew Morgan <1342360+anoadragon453@users.noreply.github.com> Date: Fri, 13 Nov 2020 16:24:04 +0000 Subject: [PATCH] Generalise _maybe_store_room_on_invite (#8754) There's a handy function called maybe_store_room_on_invite which allows us to create an entry in the rooms table for a room and its version for which we aren't joined to yet, but we can reference when ingesting events about. This is currently used for invites where we receive some stripped state about the room and pass it down via /sync to the client, without us being in the room yet. There is a similar requirement for knocking, where we will eventually do the same thing, and need an entry in the rooms table as well. Thus, reusing this function works, however its name needs to be generalised a bit. Separated out from #6739. --- changelog.d/8754.misc | 1 + synapse/handlers/federation.py | 10 ++++++---- synapse/replication/http/federation.py | 10 +++++----- synapse/storage/databases/main/room.py | 10 ++++++---- 4 files changed, 18 insertions(+), 13 deletions(-) create mode 100644 changelog.d/8754.misc diff --git a/changelog.d/8754.misc b/changelog.d/8754.misc new file mode 100644 index 000000000..0436bb1be --- /dev/null +++ b/changelog.d/8754.misc @@ -0,0 +1 @@ +Generalise `RoomStore.maybe_store_room_on_invite` to handle other, non-invite membership events. \ No newline at end of file diff --git a/synapse/handlers/federation.py b/synapse/handlers/federation.py index c38695770..69bc5ba44 100644 --- a/synapse/handlers/federation.py +++ b/synapse/handlers/federation.py @@ -67,7 +67,7 @@ from synapse.replication.http.devices import ReplicationUserDevicesResyncRestSer from synapse.replication.http.federation import ( ReplicationCleanRoomRestServlet, ReplicationFederationSendEventsRestServlet, - ReplicationStoreRoomOnInviteRestServlet, + ReplicationStoreRoomOnOutlierMembershipRestServlet, ) from synapse.state import StateResolutionStore from synapse.storage.databases.main.events_worker import EventRedactBehaviour @@ -152,12 +152,14 @@ class FederationHandler(BaseHandler): self._user_device_resync = ReplicationUserDevicesResyncRestServlet.make_client( hs ) - self._maybe_store_room_on_invite = ReplicationStoreRoomOnInviteRestServlet.make_client( + self._maybe_store_room_on_outlier_membership = ReplicationStoreRoomOnOutlierMembershipRestServlet.make_client( hs ) else: self._device_list_updater = hs.get_device_handler().device_list_updater - self._maybe_store_room_on_invite = self.store.maybe_store_room_on_invite + self._maybe_store_room_on_outlier_membership = ( + self.store.maybe_store_room_on_outlier_membership + ) # When joining a room we need to queue any events for that room up. # For each room, a list of (pdu, origin) tuples. @@ -1617,7 +1619,7 @@ class FederationHandler(BaseHandler): # keep a record of the room version, if we don't yet know it. # (this may get overwritten if we later get a different room version in a # join dance). - await self._maybe_store_room_on_invite( + await self._maybe_store_room_on_outlier_membership( room_id=event.room_id, room_version=room_version ) diff --git a/synapse/replication/http/federation.py b/synapse/replication/http/federation.py index b4f4a68b5..7a0dbb5b1 100644 --- a/synapse/replication/http/federation.py +++ b/synapse/replication/http/federation.py @@ -254,20 +254,20 @@ class ReplicationCleanRoomRestServlet(ReplicationEndpoint): return 200, {} -class ReplicationStoreRoomOnInviteRestServlet(ReplicationEndpoint): +class ReplicationStoreRoomOnOutlierMembershipRestServlet(ReplicationEndpoint): """Called to clean up any data in DB for a given room, ready for the server to join the room.
