We work through all the events with partial state, updating the state at each of them. Once it's done, we recalculate the state for the whole room, and then mark the room as having complete state.

I'm afraid this doesn't really have any tests yet. I do have some Complement tests, but they need more bits of this to land.

Part of #11249, and a follow-up to #12012.

I'm not super confident I understood all the bits, but I asked some questions which will hopefully get the ball rolling.

I'm guessing we need to persist more info to the database and then ensure that starts up again on restart?

I'm not even sure we ned any extra info in the database - all we need is a list of room ids, and we have that.

So yes, it's just a matter of starting it up again on restart.

Fair! Was mostly just curious, not asking for it to be fixed yet! 👍

Maybe put this on the background process worker?

yeah, maybe. On the other hand it does a bunch of work which is quite similar to the event creator, and it would be nice to shard it across multiple workers (as we do with event creators), so it's not entirely obvious. Either way, I'm punting the decision for now.

Maybe this is fine, but will this work OK if a second user joins from your server while we only have partial room state?

that's really a special-case of the more general problem of sending events while we have partial state. Currently, it's completely broken, but in a couple of PRs time, we'll have a thing which will wait for the resync to complete.

That makes sense, thanks! 👍 Glad to know this is something in the works already.

It seems unfortunate that these will be called separately per event, but I don't see a good way to make this method take a list of events.

I think we think about optimising it later. Hopefully there won't be a huge number of events anyway.

I'm a bit confused at where this might come from -- if we've resolved the entire room state how could there be states with partial state arriving?

These are from other servers in the room sending us events, not from the process of resolving partial state, correct?

that's right. Currently, when we get a new event over federation, we calculate the state at that event based on the state at the new event's prev_event(s). Obviously, if any of those prev_events have partial state, the state at the new event is also going to be partial. So, there is potential for a race:

  • we pull the list of partial-state events, and find event X is the only one left. We start the process of updating the state at X.
  • an event Y arrives which refers to event X in its prev_events. At this point, X still has partial state, hence so does Y. We hand off Y to be persisted by the event persistence thread.
  • We complete the de-partial-stating of X, and go round the loop again. We find there are no remaining partial state events. Hurrah!
  • Y gets persisted.
  • We attempt to mark the room as having no partial-state events. This fails, because of Y.

Obviously, there's another failure mode here, where Y's persistence happens after we mark the room as having no partial-state events. It seems like I'm going to need to revisit this. For now, I'm just going to add yet another TODO.

Synapse 1.58.0rc1 (2022-04-26)
==============================

As of this release, the groups/communities feature in Synapse is now disabled by default. See [\#11584](matrix-org/synapse#11584) for details. As mentioned in [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1580), this feature will be removed in Synapse 1.61.

Features
--------

- Implement [MSC3383](matrix-org/matrix-spec-proposals#3383) for including the destination in server-to-server authentication headers. Contributed by @Bubu and @jcgruenhage for Famedly. ([\#11398](matrix-org/synapse#11398))
- Docker images and Debian packages from matrix.org now contain a locked set of Python dependencies, greatly improving build reproducibility. ([Board](https://github.com/orgs/matrix-org/projects/54), [\#11537](matrix-org/synapse#11537))
- Enable processing of device list updates asynchronously. ([\#12365](matrix-org/synapse#12365), [\#12465](matrix-org/synapse#12465))
- Implement [MSC2815](matrix-org/matrix-spec-proposals#2815) to allow room moderators to view redacted event content. Contributed by @tulir. ([\#12427](matrix-org/synapse#12427))
- Build Debian packages for Ubuntu 22.04 "Jammy Jellyfish". ([\#12543](matrix-org/synapse#12543))

Bugfixes
--------

- Prevent a sync request from removing a user's busy presence status. ([\#12213](matrix-org/synapse#12213))
- Fix bug with incremental sync missing events when rejoining/backfilling. Contributed by Nick @ Beeper. ([\#12319](matrix-org/synapse#12319))
- Fix a long-standing bug which incorrectly caused `GET /_matrix/client/v3/rooms/{roomId}/event/{eventId}` to return edited events rather than the original. ([\#12476](matrix-org/synapse#12476))
- Fix a bug introduced in Synapse 1.27.0 where the admin API for [deleting forward extremities](https://github.com/matrix-org/synapse/blob/erikj/fix_delete_event_response_count/docs/admin_api/rooms.md#deleting-forward-extremities) would always return a count of 1, no matter how many extremities were deleted. ([\#12496](matrix-org/synapse#12496))
- Fix a long-standing bug where the image thumbnails embedded into email notifications were broken. ([\#12510](matrix-org/synapse#12510))
- Fix a bug in the implementation of [MSC3202](matrix-org/matrix-spec-proposals#3202) where Synapse would use the field name `device_unused_fallback_keys`, rather than `device_unused_fallback_key_types`. ([\#12520](matrix-org/synapse#12520))
- Fix a bug introduced in Synapse 0.99.3 which could cause Synapse to consume large amounts of RAM when back-paginating in a large room. ([\#12522](matrix-org/synapse#12522))

Improved Documentation
----------------------

- Fix rendering of the documentation site when using the 'print' feature. ([\#12340](matrix-org/synapse#12340))
- Add a manual documenting config file options. ([\#12368](matrix-org/synapse#12368), [\#12527](matrix-org/synapse#12527))
- Update documentation to reflect that both the `run_background_tasks_on` option and the options for moving stream writers off of the main process are no longer experimental. ([\#12451](matrix-org/synapse#12451))
- Update worker documentation and replace old `federation_reader` with `generic_worker`. ([\#12457](matrix-org/synapse#12457))
- Strongly recommend [Poetry](https://python-poetry.org/) for development. ([\#12475](matrix-org/synapse#12475))
- Add some example configurations for workers and update architectural diagram. ([\#12492](matrix-org/synapse#12492))
- Fix a broken link in `README.rst`. ([\#12495](matrix-org/synapse#12495))
- Add HAProxy delegation example with CORS headers to docs. ([\#12501](matrix-org/synapse#12501))
- Remove extraneous comma in User Admin API's device deletion section so that the example JSON is actually valid and works. Contributed by @olmari. ([\#12533](matrix-org/synapse#12533))

Are there plans to look at this soon™️?

I think I am running into this race with the test on matrix-org/complement#214 when sending the marker event.

The following error occurs where the query looks like: simple_insert_many_txn sql=INSERT INTO partial_state_events (room_id, event_id) VALUES(?, ?) values=[('!tNpiAqfxkwVfethRjU:hs1', '$d-ZaRzttjmLPwP8SMHHxvNiheVLozYME5stmHctL54Q')].

In the full logs (below in the collapsed section), it looks like we're calling clear_partial_state_room right before we try to do the query above to insert more partial state and the NOT NULL REFERENCES constraint doesn't like that it can't find the room_id in partial_state_rooms anymore -> sqlite3.IntegrityError: FOREIGN KEY constraint failed

Failed to handle PDU $d-ZaRzttjmLPwP8SMHHxvNiheVLozYME5stmHctL54Q
