From e7a16c6210191e9556fb1c11cbff2d98f0a5206c Mon Sep 17 00:00:00 2001 From: Richard van der Hoff Date: Mon, 22 Oct 2018 16:12:11 +0100 Subject: [PATCH] Remove redundant run_as_background_process() from pusherpool `on_new_notifications` and `on_new_receipts` in `HttpPusher` and `EmailPusher` now always return synchronously, so we can remove the `defer.gatherResults` on their results, and the `run_as_background_process` wrappers can be removed too because the PusherPool methods will now complete quickly enough. --- synapse/app/pusher.py | 4 ++-- synapse/handlers/federation.py | 4 ++-- synapse/handlers/message.py | 2 +- synapse/handlers/receipts.py | 2 +- synapse/push/emailpusher.py | 3 +-- synapse/push/httppusher.py | 2 -- synapse/push/pusherpool.py | 43 ++++------------------------------ 7 files changed, 12 insertions(+), 48 deletions(-) diff --git a/synapse/app/pusher.py b/synapse/app/pusher.py index e06b70894..83b0863f0 100644 --- a/synapse/app/pusher.py +++ b/synapse/app/pusher.py @@ -161,11 +161,11 @@ class PusherReplicationHandler(ReplicationClientHandler): else: yield self.start_pusher(row.user_id, row.app_id, row.pushkey) elif stream_name == "events": -
