* Improve federation sender performance and behaviour, add backoff * Tweaks * Tweaks * Tweaks * Take copies of events before passing to destination queues * Don't accidentally drop queued messages * Don't take copies again * Tidy up a bit * Break out statistics (tracked component-wide), report success and failures from Perform actions * Fix comment, use atomic add * Improve logic a bit, don't block on wakeup, move idle check * Don't retry sucessful invites, don't dispatch sendEvent, sendInvite etc * Dedupe destinations, fix other bug hopefully * Dispatch sends again * Federation sender to ignore invites that are destined locally * Loopback invite events * Remodel a bit with channels * Linter * Only loopback invite event if we know the room * We should tell other resident servers about the invite if we know about the room * Correct invite signing * Fix invite loopback * Check HTTP response codes, push new invites to front of queue * Review comments
