From 1182ae50635db94d3c9c47990a0befcbf6306b62 Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Wed, 1 Feb 2023 16:35:24 -0500 Subject: Add helper to parse an enum from query args & use it. (#14956) The `parse_enum` helper pulls an enum value from the query string (by delegating down to the parse_string helper with values generated from the enum). This is used to pull out "f" and "b" in most places and then we thread the resulting Direction enum throughout more code. --- synapse/federation/federation_server.py | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) (limited to 'synapse/federation/federation_server.py') diff --git a/synapse/federation/federation_server.py b/synapse/federation/federation_server.py index c9a6dfd1a4..8d36172484 100644 --- a/synapse/federation/federation_server.py +++ b/synapse/federation/federation_server.py @@ -34,7 +34,13 @@ from prometheus_client import Counter, Gauge, Histogram from twisted.internet.abstract import isIPAddress from twisted.python import failure -from synapse.api.constants import EduTypes, EventContentFields, EventTypes, Membership +from synapse.api.constants import ( + Direction, + EduTypes, + EventContentFields, + EventTypes, + Membership, +) from synapse.api.errors import ( AuthError, Codes, @@ -218,7 +224,7 @@ class FederationServer(FederationBase): return 200, res async def on_timestamp_to_event_request( - self, origin: str, room_id: str, timestamp: int, direction: str + self, origin: str, room_id: str, timestamp: int, direction: Direction ) -> Tuple[int, Dict[str, Any]]: """When we receive a federated `/timestamp_to_event` request, handle all of the logic for validating and fetching the event. @@ -228,7 +234,7 @@ class FederationServer(FederationBase): room_id: Room to fetch the event from timestamp: The point in time (inclusive) we should navigate from in the given direction to find the closest event. - direction: ["f"|"b"] to indicate whether we should navigate forward + direction: indicates whether we should navigate forward or backward from the given timestamp to find the closest event.
