* Fix incorrect juggling of logging contexts in `_PerHostRatelimiter` (#13554)Sean Quah2022-08-181-10/+7

* Track number of hosts affected by the rate limiter (#13541)Eric Eastwood2022-08-181-4/+39
| | | | | | | Track number of hosts affected by the rate limiter so we can differentiate one really noisy homeserver from a general ratelimit tuning problem across the federation. Follow-up to https://github.com/matrix-org/synapse/pull/13534 Part of https://github.com/matrix-org/synapse/issues/13356
* Add metrics to track how the rate limiter is affecting requests ↵Eric Eastwood2022-08-171-8/+29

* Instrument `FederationStateIdsServlet` - `/state_ids` (#13499)Eric Eastwood2022-08-151-0/+4
| | | Instrument FederationStateIdsServlet - `/state_ids` so it's easier to follow what's going on in Jaeger when viewing a trace.

| | | | | | | Part of #9744 Removes all redundant `# -*- coding: utf-8 -*-` lines from files, as python 3 automatically reads source code as utf-8 now. `Signed-off-by: Jonathan de Jong <jonathan@automatia.nl>`

* Performance improvements and refactor of Ratelimiter (#7595)Andrew Morgan2020-06-051-1/+1
| | | | | | | | | | While working on https://github.com/matrix-org/synapse/issues/5665 I found myself digging into the `Ratelimiter` class and seeing that it was both: * Rather undocumented, and * causing a *lot* of config checks This PR attempts to refactor and comment the `Ratelimiter` class, as well as encourage config file accesses to only be done at instantiation. Best to be reviewed commit-by-commit.
* Fixes to the federation rate limiter (#5621)Richard van der Hoff2019-07-051-8/+8
| | | | | | | - Put the default window_size back to 1000ms (broken by #5181) - Make the `rc_federation` config actually do something - fix an off-by-one error in the 'concurrent' limit - Avoid creating an unused `_PerHostRatelimiter` object for every single incoming request
* Move logging utilities out of the side drawer of util/ and into logging/ (#5606)Amber Brown2019-07-041-1/+1

* Use run_in_background in preference to preserve_fnRichard van der Hoff2018-04-271-2/+2
| | | | | | While I was going through uses of preserve_fn for other PRs, I converted places which only use the wrapped function once to use run_in_background, to avoid creating the function object.
* Remove some unused functions (#711)Mark Haines2016-04-081-14/+0
| | | | | | | | * Remove some unused functions * get_room_events_stream is only used in tests * is_exclusive_room might actually be something we want
