* Convert some util functions to async (#8035)Patrick Cloke2020-08-061-10/+6
|
* Fix some spelling mistakes / typos. (#7811)Patrick Cloke2020-07-091-2/+2
|
* Fix errors storing large retry intervals.Erik Johnston2019-10-021-1/+1
| | | | | | | | | We have set the max retry interval to a value larger than a postgres or sqlite int can hold, which caused exceptions when updating the destinations table. To fix postgres we need to change the column to a bigint, and for sqlite we lower the max interval to 2**62 (which is still incredibly long).
* Add 'failure_ts' column to 'destinations' table (#6016)Richard van der Hoff2019-09-171-1/+15
| | | | Track the time that a server started failing at, for general analysis purposes.
* Remove the cap on federation retry interval. (#6026)Richard van der Hoff2019-09-121-2/+2
| | | | | | Essentially the intention here is to end up blacklisting servers which never respond to federation requests. Fixes https://github.com/matrix-org/synapse/issues/5113.
* Fix bug in calculating the federation retry backoff period (#6025)Richard van der Hoff2019-09-121-2/+3
| | | | This was intended to introduce an element of jitter; instead it gave you a 30/60 chance of resetting to zero.
* Clean up some code in the retry logic (#6017)Richard van der Hoff2019-09-111-16/+13
| | | | * remove some unused code * make things which were constants into constants for efficiency and clarity
* Replace returnValue with return (#5736)Amber Brown2019-07-231-9/+7
|
* Move logging utilities out of the side drawer of util/ and into logging/ (#5606)Amber Brown2019-07-041-2/+2
|
* Call RetryLimiter correctly (#5340)Richard van der Hoff2019-06-041-1/+6
| | | Fixes a regression introduced in #5335.
* Avoid rapidly backing-off a server if we ignore the retry intervalRichard van der Hoff2019-06-031-23/+37
|
* Improve the logging when handling a federation transaction (#3904)Richard van der Hoff2018-09-191-1/+1
| | | | | | | | | | 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.
* run isortAmber Brown2018-07-091-5/+4
|
* 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.
* Add federation_domain_whitelist option (#2820)Matthew Hodgson2018-01-221-0/+12
| | | | | | Add federation_domain_whitelist gives a way to restrict which domains your HS is allowed to federate with. useful mainly for gracefully preventing a private but internet-connected HS from trying to federate to the wider public Matrix network
* replace 'except:' with 'except Exception:'Richard van der Hoff2017-10-231-1/+1
| | | | what could possibly go wrong
* Merge pull request #2050 from matrix-org/rav/federation_backoffRichard van der Hoff2017-03-231-4/+25
|\ | | | | push federation retry limiter down to matrixfederationclient
| * Ignore backoff history for invites, aliases, and roomdirsRichard van der Hoff2017-03-231-2/+11
| | | | | | | | | | Add a param to the federation client which lets us ignore historical backoff data for federation queries, and set it for a handful of operations.
| * push federation retry limiter down to matrixfederationclientRichard van der Hoff2017-03-231-2/+14
| | | | | | | | | | rather than having to instrument everywhere we make a federation call, make the MatrixFederationHttpClient manage the retry limiter.
* | Fix a couple of logcontext leaksRichard van der Hoff2017-03-231-2/+3
|/ | | | | Use preserve_fn to correctly manage the logcontexts around things we don't want to yield on.

Factor out the pre destination retry logic from TransactionQueue so it can be reused in both get_pdu and crypto.keyring
