* Remove redundant types from comments. (#14412)Patrick Cloke2022-11-161-1/+1
| | | | | | | Remove type hints from comments which have been added as Python type hints. This helps avoid drift between comments and reality, as well as removing redundant information. Also adds some missing type hints which were simple to fill in.

* 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

* 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

* Make FederationRateLimiter queue requests properlyRichard van der Hoff2018-07-131-10/+23
| | | | | | | | popitem removes the *most recent* item by default [1]. We want the oldest. Fixes #3524 [1]: https://docs.python.org/2/library/collections.html#collections.OrderedDict.popitem

* 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
