Run Black. (#5482) 2019-06-20 19:32:02 +10:00
Richard van der Hoff c7325776a7 Remove redundant PreserveLoggingContext
Both (!) things that register as replication listeners do the right thing wrt
logcontexts, so this is redundant.

Richard van der Hoff daa10e3e66 Remove unused `wait_for_replication` method
I guess this was used once? It's not now, anyway.

Make the metrics less racy (#4061) 2018-10-19 21:45:45 +11:00
Richard van der Hoff a87d419a85 Run notify_app_services as a bg process
This ensures that its resource usage metrics get recorded somewhere rather than
getting lost.

(It also fixes an error when called from a nested logging context which
completes before the bg process)

Erik Johnston 9407bcf37a Replace custom DeferredTimeoutError with defer.TimeoutError 2018-09-19 11:07:29 +01:00
Erik Johnston a334e1cace Update to use new timeout function everywhere.
The existing deferred timeout helper function (and the one into twisted)
suffer from a bug when a deferred's canceller throws an exception, #3842.

The new helper function doesn't suffer from this problem.

Matthew Hodgson 5797f5542b WIP to announce deleted devices over federation
Previously we queued up the poke correctly when the device was deleted,
but then the actual EDU wouldn't get sent, as the device was no longer known.
Instead, we now send EDUs for deleted devices too if there's a poke for them.

Richard van der Hoff 9d2c1b8429 Backport deferred.addTimeout
Twisted 16.0 doesn't have addTimeout, so let's backport it.

Richard van der Hoff 9255a6cb17 Improve exception handling for background processes
There were a bunch of places where we fire off a process to happen in the
background, but don't have any exception handling on it - instead relying on
the unhandled error being logged when the relevent deferred gets
garbage-collected.

This is unsatisfactory for a number of reasons:
 - logging on garbage collection is best-effort and may happen some time after
   the error, if at all
 - it can be hard to figure out where the error actually happened.
 - it is logged as a scary CRITICAL error which (a) I always forget to grep for
   and (b) it's not really CRITICAL if a background process we don't care about
   fails.

So this is an attempt to add exception handling to everything we fire off into
the background.

Richard van der Hoff 1ea904b9f0 Use deferred.addTimeout instead of time_bound_deferred
This doesn't feel like a wheel we need to reinvent.

Richard van der Hoff d4fb4f7c52 Clear logcontext before starting fed txn queue runner
These processes take a long time compared to the request, so there is lots of
"Entering|Restoring dead context" in the logs. Let's try to shut it up a bit.

Richard van der Hoff 65e1683680 Remove spurious PreserveLoggingContext
In `on_new_room_event`, remove `PreserveLoggingContext` - we can call its
subroutines with the logcontext set.

Richard van der Hoff feb496056e preserve_fn some deferred-returning things
In `Notifier._on_new_room_event`, `preserve_fn` around its subroutines which
return deferreds, so that it is safe to call it with an active logcontext.

Richard van der Hoff 773e1c6d68 Remove spurious @preserve_fn decorators
Remove `@preserve_fn` decorators on `on_new_room_event`,
`_notify_pending_new_room_events`, `_on_new_room_event`, `on_new_event`, and
`on_new_replication_data` - none of these functions return a deferred, and the
decorator does nothing unless the wrapped function returns a deferred, so the
decorator was a no-op.

Erik Johnston be14c24cea Fix rare notifier bug where listeners dont timeout
There was a race condition that caused the notifier to 'miss' the
timeout notification, since there were no other checks for the timeout
this caused listeners to get stuck in a loop until something happened.

Erik Johnston 9da84a9a1e Make AppserviceHandler stream events from database
This is for two reasons:

1. Suppresses duplicates correctly, as the notifier doesn't do any
   duplicate suppression.
2. Makes it easier to connect the AppserviceHandler to the replication
   stream.

Mark Haines 88625db05f Notify users for events in rooms they join.
Change how the notifier updates the map from room_id to user streams on
receiving a join event. Make it update the map when it notifies for the
join event, rather than using the "user_joined_room" distributor signal

Mark Haines c626fc576a Move the AS handler out of the Handlers object.
Access it directly from the homeserver itself. It already wasn't
inheriting from BaseHandler storing it on the Handlers object was
already somewhat dubious.

Mark Haines 2a37467fa1 Use google style doc strings.
pycharm supports them so there is no need to use the other format.

Might as well convert the existing strings to reduce the risk of
people accidentally cargo culting the wrong doc string format.
