HTTP 401 responses returned by Mastodon's inbox controller may
be temporary if, for instance, the requesting user's actor/key json
could not be retrieved in a timely fashion. This changes allow retries
instead of dropping the message entirely.
Also added HTTP 408 as that error is by nature temporary.
* If an Update is signed with known key, skip re-following procedure
Because it means the remote actor did *not* lose their database
* Add CLI method for rotating keys
bin/tootctl accounts rotate [USERNAME]
Generates a new RSA key per account and sends out an Update activity
signed with the old key.
* Key rotation: Space out Update fan-outs every 5 minutes per 1000 accounts
* Skip suspended accounts in key rotation
* Do not raise delivery failure on 4xx errors, increase stoplight threshold
Stoplight failure threshold from 3 to 10
Status code 429 will raise a failure/get retried
* Oops
HTTP connections must be explicitly closed in many cases, and letting
perform method close connections makes its callers less redundant and
prevent them from forgetting to close connections.
Currently, Mastodon will retry delivering toots for a bit over 1 hour.
This is a very short timespan when considering private and direct toots, which
cannot be seen by the recipient at all after the delivery attempts have failed.
Ideally, private and direct toots should have a different number of retries,
but I do not know how to do that.
