From 364d6167926d5d8b2a312e3d35623d2e05330e0a Mon Sep 17 00:00:00 2001 From: Mark Haines Date: Thu, 16 Jun 2016 12:53:15 +0100 Subject: [PATCH] Access the event_cache_size directly from the server object. This means that the workers can override the event_cache_size directly without clobbering the value in the main synapse config. --- synapse/app/pusher.py | 6 +++--- synapse/app/synchrotron.py | 6 +++--- synapse/config/workers.py | 14 -------------- synapse/server.py | 3 +++ synapse/storage/_base.py | 2 +- 5 files changed, 10 insertions(+), 21 deletions(-) diff --git a/synapse/app/pusher.py b/synapse/app/pusher.py index a26a3bd394..5d4db4f892 100644 --- a/synapse/app/pusher.py +++ b/synapse/app/pusher.py @@ -18,7 +18,6 @@ import synapse from synapse.server import HomeServer from synapse.config._base import ConfigError -from synapse.config.workers import clobber_with_worker_config from synapse.config.logger import setup_logging from synapse.config.homeserver import HomeServerConfig from synapse.http.site import SynapseSite @@ -241,6 +240,9 @@ class PusherServer(HomeServer): logger.exception("Error replicating from %r", replication_url) yield sleep(30) + def get_event_cache_size(self): + return self.worker_config.event_cache_size + def setup(worker_name, config_options): try: @@ -255,8 +257,6 @@ def setup(worker_name, config_options): setup_logging(worker_config.log_config, worker_config.log_file) - clobber_with_worker_config(config, worker_config) - if config.start_pushers: sys.stderr.write( "\nThe pushers must be disabled in the main synapse process" diff --git a/synapse/app/synchrotron.py b/synapse/app/synchrotron.py index 4443c73e6a..d10bb2b3f0 100644 --- a/synapse/app/synchrotron.py +++ b/synapse/app/synchrotron.py @@ -20,7 +20,6 @@ from synapse.api.constants import EventTypes, PresenceState from synapse.config._base import ConfigError from synapse.config.homeserver import HomeServerConfig from synapse.config.logger import setup_logging -from synapse.config.workers import clobber_with_worker_config from synapse.events import FrozenEvent from synapse.handlers.presence import PresenceHandler from synapse.http.site import SynapseSite @@ -404,6 +403,9 @@ class SynchrotronServer(HomeServer): def build_typing_handler(self): return SynchrotronTyping(self) + def get_event_cache_size(self): + return self.worker_config.event_cache_size + def start(worker_name, config_options): try: @@ -418,8 +420,6 @@ def start(worker_name, config_options): setup_logging(worker_config.log_config, worker_config.log_file) - clobber_with_worker_config(config, worker_config) - database_engine = create_engine(config.database_config) ss = SynchrotronServer( diff --git a/synapse/config/workers.py b/synapse/config/workers.py index f2c77ef59a..503358e03e 100644 --- a/synapse/config/workers.py +++ b/synapse/config/workers.py @@ -33,20 +33,6 @@ Worker = collections.namedtuple("Worker", [ ]) -def clobber_with_worker_config(config, worker_config): - """Overrides some of the keys of the main config with worker-specific - values.
