Send Application Service Events (#477) * Prevent sql scanning into nil value in accounts_table Signed-off-by: Andrew Morgan <andrewm@matrix.org> * Remove uneccessary logging, null checking * Don't forget to set the localpart * Simplify error checking * Store And Send Application Service Events * Modify INSTALL.md and dendrite-config.yaml for the new appservice database * Correct all instances of casing on 'application service' to align with spec * Store incoming events that an app service is interested in in the database to be later read by transaction workers. * Retrieve these events from transaction workers, one per AS. * Minimal transaction ID data is stored as well to recover after server failure. * Send events to AS and exponentially backoff on failure. Signed-off-by: Andrew Morgan <andrewm@matrix.org> * Finish my own sentences. * Fix up database interaction * Change to event-based AS sending * Reduce cyclomatic complexity * Appease the errcheck gods * Delete by int ID instead of string. This was causing some events to not be deleted, as < an eventID doesn't really make much sense. * Check if there are more events to send before sleeping * Send same transaction if last send attempt failed * Don't backoff on non-200s, tight send loop, 1 event query * Remove tight send loop. Fix events not being deleted * Additionally order by event id, track main.go * Return the last txnID, which our events are using * Remove old main.go file * Prevent duplicate events from being sent... * Strip event content if it doesn't contain anything Signed-off-by: Andrew Morgan <andrewm@matrix.org> * Update gomatrixserverlib and use Unsigned AS event prop * Fixes * Fix sync server comment * Remove unnecessary printlns * Use logrus Fields * Worker state methods * Remove sillyness * Fix up event filtering * Handle transaction event limit in loop * Switch to using a sequence for transaction IDs * Don't verify self-signed AS certificates * Fix logging * Use gmsl.Event instead of AS-only event in transactions Also clear up the logic on lookupStateEvents a little bit. * Change invalid_txn_id to global (for efficiency) * Use a bool for EventsReady instead of an int
