From 667fba68f3ca808f48143a2a739a54665b0162c6 Mon Sep 17 00:00:00 2001 From: Richard van der Hoff Date: Wed, 18 Jul 2018 14:35:24 +0100 Subject: Run things as background processes This fixes #3518, and ensures that we get useful logs and metrics for lots of things that happen in the background. (There are certainly more things that happen in the background; these are just the common ones I've found running a single-process synapse locally). --- synapse/storage/events.py | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) (limited to 'synapse/storage/events.py') diff --git a/synapse/storage/events.py b/synapse/storage/events.py index 2aaab0d02c..4ff0fdc4ab 100644 --- a/synapse/storage/events.py +++ b/synapse/storage/events.py @@ -33,12 +33,13 @@ from synapse.api.errors import SynapseError # these are only included to make the type annotations work from synapse.events import EventBase # noqa: F401 from synapse.events.snapshot import EventContext # noqa: F401 +from synapse.metrics.background_process_metrics import run_as_background_process from synapse.storage.events_worker import EventsWorkerStore from synapse.types import RoomStreamToken, get_domain_from_id from synapse.util.async import ObservableDeferred from synapse.util.caches.descriptors import cached, cachedInlineCallbacks from synapse.util.frozenutils import frozendict_json_encoder -from synapse.util.logcontext import PreserveLoggingContext, make_deferred_yieldable +from synapse.util.logcontext import make_deferred_yieldable from synapse.util.logutils import log_function from synapse.util.metrics import Measure @@ -155,11 +156,8 @@ class _EventPeristenceQueue(object): self._event_persist_queues[room_id] = queue self._currently_persisting_rooms.discard(room_id) - # set handle_queue_loop off on the background.
