Catch-up after Federation Outage (split, 1) #8230

reivilibre · 2020-09-02T14:37:34Z

This adds and keeps updated destination_rooms, a table used for determining the latest messages for each (destination, room) pair.

this is going to need a newsfile.

comment please. why are we doing this?

Is this OK?

+            "   SELECT stream_ordering FROM events_to_purge"
+            "       JOIN events USING (event_id)"
+            ")"


destination_rooms doesn't have an index on stream_ordering, so this is going to be very inefficient.

Can we give destination_rooms an index on room_id?

Following you about the missing index, but are you saying you want both indices on stream_ordering and room_id, or just the latter (and then to reword the query to use it)?

just the latter. Hopefully it will need less index updating than an index on stream_ordering.

btw: I think the purge_room api might also need an update (https://github.com/matrix-org/synapse/blob/master/docs/admin_api/purge_room.md)

Is this better?

lgtm, but as per #synapse-dev: could you hold off merging it for now?

+Track the latest event for every destination and room for catch-up after federation outage.


once you land the other parts of this feature, it'll be good to update this so that the changelog entries get combined.

Synapse 1.21.2 (2020-10-15) =========================== Debian packages and Docker images have been rebuilt using the latest versions of dependency libraries, including authlib 0.15.1. Please see bugfixes below. Security advisory ----------------- * HTML pages served via Synapse were vulnerable to cross-site scripting (XSS) attacks. All server administrators are encouraged to upgrade. ([\#8444](matrix-org/synapse#8444)) ([CVE-2020-26891](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-26891)) This fix was originally included in v1.21.0 but was missing a security advisory. This was reported by [Denis Kasak](https://github.com/dkasak). Bugfixes -------- - Fix rare bug where sending an event would fail due to a racey assertion. ([\#8530](matrix-org/synapse#8530)) - An updated version of the authlib dependency is included in the Docker and Debian images to fix an issue using OpenID Connect. See [\#8534](matrix-org/synapse#8534) for details. Synapse 1.21.1 (2020-10-13) =========================== This release fixes a regression in v1.21.0 that prevented debian packages from being built. It is otherwise identical to v1.21.0. Synapse 1.21.0 (2020-10-12) =========================== No significant changes since v1.21.0rc3. As [noted in v1.20.0](https://github.com/matrix-org/synapse/blob/release-v1.21.0/CHANGES.md#synapse-1200-2020-09-22), a future release will drop support for accessing Synapse's [Admin API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api) under the `/_matrix/client/*` endpoint prefixes. At that point, the Admin API will only be accessible under `/_synapse/admin`. Synapse 1.21.0rc3 (2020-10-08) ============================== Bugfixes -------- - Fix duplication of events on high traffic servers, caused by PostgreSQL `could not serialize access due to concurrent update` errors. ([\#8456](matrix-org/synapse#8456)) Internal Changes ---------------- - Add Groovy Gorilla to the list of distributions we build `.deb`s for. ([\#8475](matrix-org/synapse#8475)) Synapse 1.21.0rc2 (2020-10-02) ============================== Features -------- - Convert additional templates from inline HTML to Jinja2 templates. ([\#8444](matrix-org/synapse#8444)) Bugfixes -------- - Fix a regression in v1.21.0rc1 which broke thumbnails of remote media. ([\#8438](matrix-org/synapse#8438)) - Do not expose the experimental `uk.half-shot.msc2778.login.application_service` flow in the login API, which caused a compatibility problem with Element iOS. ([\#8440](matrix-org/synapse#8440)) - Fix malformed log line in new federation "catch up" logic. ([\#8442](matrix-org/synapse#8442)) - Fix DB query on startup for negative streams which caused long start up times. Introduced in [\#8374](matrix-org/synapse#8374). ([\#8447](matrix-org/synapse#8447)) Synapse 1.21.0rc1 (2020-10-01) ============================== Features -------- - Require the user to confirm that their password should be reset after clicking the email confirmation link.
