From 3dd175b628bab5638165f20de9eade36a4e88147 Mon Sep 17 00:00:00 2001 From: Quentin Gliech Date: Mon, 22 Aug 2022 15:17:59 +0200 Subject: `synapse.api.auth.Auth` cleanup: make permission-related methods use `Requester` instead of the `UserID` (#13024) Part of #13019 This changes all the permission-related methods to rely on the Requester instead of the UserID. This is a first step towards enabling scoped access tokens at some point, since I expect the Requester to have scope-related informations in it. It also changes methods which figure out the user/device/appservice out of the access token to return a Requester instead of something else. This avoids having store-related objects in the methods signatures. --- synapse/api/auth.py | 202 ++++++++++++++++++++++++---------------------------- 1 file changed, 95 insertions(+), 107 deletions(-) (limited to 'synapse/api/auth.py') diff --git a/synapse/api/auth.py b/synapse/api/auth.py index 523bad0c55..9a1aea083f 100644 --- a/synapse/api/auth.py +++ b/synapse/api/auth.py @@ -37,8 +37,7 @@ from synapse.logging.opentracing import ( start_active_span, trace, ) -from synapse.storage.databases.main.registration import TokenLookupResult -from synapse.types import Requester, UserID, create_requester +from synapse.types import Requester, create_requester if TYPE_CHECKING: from synapse.server import HomeServer @@ -70,14 +69,14 @@ class Auth: async def check_user_in_room( self, room_id: str, - user_id: str, + requester: Requester, allow_departed_users: bool = False, ) -> Tuple[str, Optional[str]]: """Check if the user is in the room, or was at some point.
