From 950bb0305fc3c114f456eb4e2a806014150545d2 Mon Sep 17 00:00:00 2001 From: Richard van der Hoff <1389908+richvdh@users.noreply.github.com> Date: Thu, 19 Nov 2020 10:05:33 +0000 Subject: Consistently use room_id from federation request body (#8776) * Consistently use room_id from federation request body Some federation APIs have a redundant `room_id` path param (see https://github.com/matrix-org/matrix-doc/issues/2330). We should make sure we consistently use either the path param or the body param, and the body param is easier. * Kill off some references to "context" Once upon a time, "rooms" were known as "contexts". I think this kills of the last references to "contexts". --- synapse/federation/federation_server.py | 23 +++++------ synapse/federation/transport/server.py | 68 ++++++++++++++++----------------- synapse/handlers/federation.py | 10 ++--- 3 files changed, 48 insertions(+), 53 deletions(-) (limited to 'synapse') diff --git a/synapse/federation/federation_server.py b/synapse/federation/federation_server.py index 23278e36b7..4b6ab470d0 100644 --- a/synapse/federation/federation_server.py +++ b/synapse/federation/federation_server.py @@ -49,6 +49,7 @@ from synapse.federation.federation_base import FederationBase, event_from_pdu_js from synapse.federation.persistence import TransactionActions from synapse.federation.units import Edu, Transaction from synapse.http.endpoint import parse_server_name +from synapse.http.servlet import assert_params_in_dict from synapse.logging.context import ( make_deferred_yieldable, nested_logging_context, @@ -391,7 +392,7 @@ class FederationServer(FederationBase): TRANSACTION_CONCURRENCY_LIMIT, ) -
