From a70a801184814d116ed5b10a952e17c45df7bfc8 Mon Sep 17 00:00:00 2001 From: Erik Johnston Date: Fri, 30 Jan 2015 13:34:01 +0000 Subject: Fix bug where we superfluously asked for current state. Change API of /query_auth/ so that we don't duplicate events in the response. --- synapse/api/auth.py | 2 ++ synapse/federation/federation_client.py | 7 +---- synapse/federation/federation_server.py | 12 ++++---- synapse/handlers/federation.py | 51 ++++++++++++--------------------- synapse/state.py | 20 ++++++++++--- 5 files changed, 43 insertions(+), 49 deletions(-) diff --git a/synapse/api/auth.py b/synapse/api/auth.py index 3471afd7e7..37e31d2b6f 100644 --- a/synapse/api/auth.py +++ b/synapse/api/auth.py @@ -102,6 +102,8 @@ class Auth(object): def check_host_in_room(self, room_id, host): curr_state = yield self.state.get_current_state(room_id) + logger.debug("Got curr_state %s", curr_state) + for event in curr_state: if event.type == EventTypes.Member: try: diff --git a/synapse/federation/federation_client.py b/synapse/federation/federation_client.py index 1173ca817b..e1539bd0e0 100644 --- a/synapse/federation/federation_client.py +++ b/synapse/federation/federation_client.py @@ -357,15 +357,10 @@ class FederationClient(object): for e in content["auth_chain"] ] - missing = [ - (yield self._check_sigs_and_hash(self.event_from_pdu_json(e))) - for e in content.get("missing", []) - ] - ret = { "auth_chain": auth_chain, "rejects": content.get("rejects", []), - "missing": missing, + "missing": content.get("missing", []), } defer.returnValue(ret) diff --git a/synapse/federation/federation_server.py b/synapse/federation/federation_server.py index 845a07a3a3..84ed0a0ba0 100644 --- a/synapse/federation/federation_server.py +++ b/synapse/federation/federation_server.py @@ -252,11 +252,8 @@ class FederationServer(object): e.get_pdu_json(time_now) for e in ret["auth_chain"] ], - "rejects": content.get("rejects", []), - "missing": [ - e.get_pdu_json(time_now) - for e in ret.get("missing", []) - ], + "rejects": ret.get("rejects", []), + "missing": ret.get("missing", []), } defer.returnValue( @@ -372,7 +369,10 @@ class FederationServer(object): logger.exception("Failed to get PDU") fetch_state = True else: - fetch_state = True + prevs = {e_id for e_id, _ in pdu.prev_events} + seen = set(have_seen.keys()) + if prevs - seen: + fetch_state = True else: fetch_state = True diff --git a/synapse/handlers/federation.py b/synapse/handlers/federation.py index cc22f21cd1..35cad4182a 100644 --- a/synapse/handlers/federation.py +++ b/synapse/handlers/federation.py @@ -121,38 +121,18 @@ class FederationHandler(BaseHandler): ) if not is_in_room and not event.internal_metadata.is_outlier(): logger.debug("Got event for room we're not in.") - - replication = self.replication_layer - - if not state: - state, auth_chain = yield replication.get_state_for_room( - origin, room_id=event.room_id, event_id=event.event_id, - ) - - if not auth_chain: - auth_chain = yield replication.get_event_auth( - origin, - context=event.room_id, - event_id=event.event_id, - ) - - for e in auth_chain: - e.internal_metadata.outlier = True - try: - yield self._handle_new_event(origin, e) - except: - logger.exception( - "Failed to handle auth event %s", - e.event_id, - ) - current_state = state - if state: + if state and auth_chain is not None: for e in state: e.internal_metadata.outlier = True try: - yield self._handle_new_event(origin, e) + auth_ids = [e_id for e_id, _ in e.auth_events] + auth = { + (e.type, e.state_key): e for e in auth_chain + if e.event_id in auth_ids + } + yield self._handle_new_event(origin, e, auth_events=auth) except: logger.exception( "Failed to handle state event %s", @@ -809,18 +789,23 @@ class FederationHandler(BaseHandler): ) # 3.
