I've been thinking about what I would expect to see before I'm happy to resolve my concern about the lack of an implementation.

Implementation: matrix-org/synapse@ccdcc7f

This is noted, and thanks, but I'd like to see the following:

  • a Synapse has been deployed with a test room version exactly matching the proposed parameters and that people have actually sent messages through it and they have been correctly received. In particular my understanding is that substantial parts of MSC3083 haven't yet been tested outside a development environment.
  • Given our recent discovery of the problem with redactions, I think some manual testing that auth still works when various bits of the room state are redacted would be wise.
  • I'd like to know that somebody has tested the test room version with Sytest's --room-version (and Complement's equivalent, if there is one).

Thia has been done, but needs matrix-org/sytest#1100 so that the fake server knows about the room version.

For the record, I was somewhat expecting the sytesting to happen against org.matrix.msc3083.v2 (or whatever) to save having to wait for this MSC to complete. But I realise that means more sytest PRs, and your approach of using a sytest branch is equally valid.

@clokep: how are the other two bullet points looking?

Given our recent discovery of the problem with redactions, I think some manual testing that auth still works when various bits of the room state are redacted would be wise.

I tested this manually again by:

  1. Creating a test room set to join via a space.
  2. Ensuring that I could join the space, then room.
  3. Ensuring that joining the room first does not work.
  4. Ensuring that invites work.
  5. I then redacted the m.room.join_rules event.
  6. I then repeated tests 2 - 4 with new users and ensured the checks were still enforced by the server.

Does that sound sufficient or have I missed something?

matrix.org now supports the org.matrix.msc3083.v2 room and I have created a test room which is joinable via membership in #community:matrix.org. This is not quite "exactly matching the proposed parameters" however as org.matrix.msc3083.v2 is based on room version 6, not room version 7 (it doesn't support knocking).

it sounds grand to me.

as a base and incorporating the following MSCs:

* [MSC3083](https://github.com/matrix-org/matrix-doc/pull/3083) - Restricting room
membership based on membership in other rooms

Though other MSCs are capable of being included in this version, they do not have
sufficient implementation to be considered for this room version. A future room
version may include them.

Room version `8` upon being added to the specification shall be considered stable.
No other room versions are affected by this MSC. Before room version `8` can enter
the specification, MSC3083 needs to complete its final comment period.
