Fix UnicodeDecodeError when postgres is not configured in english (#4253)
This is a bit of a half-assed effort at fixing https://github.com/matrix-org/synapse/issues/4252. Fundamentally the right answer is to drop support for Python 2.

Correctly account for cpu usage by background threads (#4074)
Wrap calls to deferToThread() in a thing which uses a child logcontext to
attribute CPU usage to the right request.

While we're in the area, remove the logcontext_tracer stuff, which is never
used, and afaik doesn't work.

Fixes #4064

Erik Johnston f7199e8734 Log looping call exceptions
If a looping call function errors, then it kills the loop entirely.
Currently it throws away the exception logs, so we should make it
actually log them.

Include eventid in log lines when processing incoming federation transactions (#3959)
when processing incoming transactions, it can be hard to see what's going on,
because we process a bunch of stuff in parallel, and because we may end up
recursively working our way through a chain of three or four events.

This commit creates a way to use logcontexts to add the relevant event ids to
the log lines.

Erik Johnston 3baf6e1667 Fix ExpiringCache.__len__ to be accurate
It used to try and produce an estimate, which was sometimes negative.
This caused metrics to be sad, so lets always just calculate it from
scratch.

(This appears to have been a longstanding bug, but one which has been made more
of a problem by #3932 and #3933).

(This was originally done by Erik as part of #3933. I'm cherry-picking it
because really it's a fix in its own right)

Erik Johnston 8601c24287 Fix some instances of ExpiringCache not expiring cache items
ExpiringCache required that `start()` be called before it would actually
start expiring entries. A number of places didn't do that.

This PR removes `start` from ExpiringCache, and automatically starts
backround reaping process on creation instead.

Improve the logging when handling a federation transaction (#3904)
Let's try to rationalise the logging that happens when we are processing an
incoming transaction, to make it easier to figure out what is going wrong when
they take ages. In particular:

- make everything start with a [room_id event_id] prefix
- make sure we log a warning when catching exceptions rather than just turning
  them into other, more cryptic, exceptions.

Erik Johnston 6c48aa0256 Run canceller first to allow it to generate correct error 2018-09-19 11:07:27 +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.

Erik Johnston 24efb2a70d Fix timeout function
Turns out deferred.cancel sometimes throws, so we do that last to ensure
that we always do resolve the new deferred.

This fixes bugs introduced in #3700, by making sure that we behave sanely
when an incoming connection is closed before the headers are read.

Richard van der Hoff 55e6bdf287 Robustness fix for logcontext filter
Make the logcontext filter not explode if it somehow ends up with a logcontext
of None, since that infinite-loops the whole logging system.

Richard van der Hoff 638d35ef08 Fix linearizer cancellation on twisted < 18.7
Turns out that cancellation of inlineDeferreds didn't really work properly
until Twisted 18.7. This commit refactors Linearizer.queue to avoid
inlineCallbacks.

Richard van der Hoff 03751a6420 Fix some looping_call calls which were broken in #3604
It turns out that looping_call does check the deferred returned by its
callback, and (at least in the case of client_ips), we were relying on this,
and I broke it in #3604.

Update run_as_background_process to return the deferred, and make sure we
return it to clock.looping_call.
