From 3ebb6694f018eedb7d3c4fda829540f07b45a5b1 Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Wed, 11 Aug 2021 15:04:51 -0400 Subject: Allow requesting the summary of a space which is joinable. (#10580) As opposed to only allowing the summary of spaces which the user is already in or has world-readable visibility. This makes the logic consistent with whether a space/room is returned as part of a space and whether a space summary can start at a space. --- synapse/handlers/space_summary.py | 31 ++++++++++++++++++------------- 1 file changed, 18 insertions(+), 13 deletions(-) (limited to 'synapse/handlers/space_summary.py') diff --git a/synapse/handlers/space_summary.py b/synapse/handlers/space_summary.py index 8c9852bc89..893546e661 100644 --- a/synapse/handlers/space_summary.py +++ b/synapse/handlers/space_summary.py @@ -38,7 +38,7 @@ from synapse.api.constants import ( Membership, RoomTypes, ) -from synapse.api.errors import Codes, SynapseError +from synapse.api.errors import AuthError, Codes, SynapseError from synapse.events import EventBase from synapse.events.utils import format_event_for_client_v2 from synapse.types import JsonDict @@ -91,7 +91,6 @@ class SpaceSummaryHandler: def __init__(self, hs: "HomeServer"): self._clock = hs.get_clock() - self._auth = hs.get_auth() self._event_auth_handler = hs.get_event_auth_handler() self._store = hs.get_datastore() self._event_serializer = hs.get_event_client_serializer() @@ -153,9 +152,13 @@ class SpaceSummaryHandler: Returns: summary dict to return """ - # first of all, check that the user is in the room in question (or it's - # world-readable) - await self._auth.check_user_in_room_or_world_readable(room_id, requester) + # First of all, check that the room is accessible. + if not await self._is_local_room_accessible(room_id, requester): + raise AuthError( + 403, + "User %s not in room %s, and room previews are disabled" + % (requester, room_id), + ) # the queue of rooms to process room_queue = deque((_RoomQueueEntry(room_id, ()),)) @@ -324,11 +327,13 @@ class SpaceSummaryHandler: ) -> JsonDict: """See docstring for SpaceSummaryHandler.get_room_hierarchy.""" - # first of all, check that the user is in the room in question (or it's - # world-readable) - await self._auth.check_user_in_room_or_world_readable( - requested_room_id, requester - ) + # First of all, check that the room is accessible. + if not await self._is_local_room_accessible(requested_room_id, requester): + raise AuthError( + 403, + "User %s not in room %s, and room previews are disabled" + % (requester, requested_room_id), + ) # If this is continuing a previous session, pull the persisted data. if from_token: @@ -612,7 +617,7 @@ class SpaceSummaryHandler: return results async def _is_local_room_accessible( - self, room_id: str, requester: Optional[str], origin: Optional[str] + self, room_id: str, requester: Optional[str], origin: Optional[str] = None ) -> bool: """ Calculate whether the room should be shown in the spaces summary. @@ -766,7 +771,7 @@ class SpaceSummaryHandler: # Finally, check locally if we can access the room.
