* Add mscs/hooks package, begin work for msc2836
* Flesh out hooks and add SQL schema
* Begin implementing core msc2836 logic
* Add test harness
* Linting
* Implement visibility checks; stub out APIs for tests

Other events cannot assert the true room_id/servers for the
parent event, only make claims to them, hence why this is
edge metadata.

It looks like the spec calls for these to be 400, rather than 403: https://matrix.org/docs/spec/client_server/r0.6.1#post-matrix-client-r0-rooms-roomid-forget

* Update gomatrixserverlib
* Reject make_join when no room members are left
* Revert some changes from wrong branch
* Distinguish between room not existing and room being abandoned on this server
* nolint
* WIP Event rejection
* Still send back errors for rejected events
Instead, discard them at the federationapi /send layer rather than
re-implementing checks at the clientapi/PerformJoin layer.
* Implement rejected events
Critically, rejected events CAN cause state resolution to happen
as it can merge forks in the DAG. This is fine, _provided_ we
do not add the rejected event when performing state resolution,
which is what this PR does. It also fixes the error handling
when NotAllowed happens, as we were checking too early and needlessly
handling NotAllowed in more than one place.
* Update test to match reality
* Modify InputRoomEvents to no longer return an error
Errors do not serialise across HTTP boundaries in polylith mode,
so instead set fields on the InputRoomEventsResponse. Add `Err()`
function to make the API shape basically the same.
* Remove redundant returns; linting
* Update blacklist
* SendEventWithState events as new

* Remove QueryBulkStateContent from current state server
Expected fail due to db impl not existing
* Implement query bulk state content
* Fix up rejecting invites over federation
* Fix bulk content marshalling
* Move currentstateserver API to roomserver
Stub out DB functions for now, nothing uses the roomserver version yet.
* Allow it to startup
* Implement some current-state-server storage interface functions
* Add missing package
* Initial FIFOing of roomserver inputs
* Remove EventID response from api.InputRoomEventsResponse
* Don't send back event ID unnecessarily
* Fix ordering hopefully
* Reduce copies, use buffered task channel to reduce contention on other rooms
* Fix error handling
* Make PerformJoin send input membership event
* Invite input room events in separate goroutine
* Don't limit roomserver input events using request context
* Synchronous input room events
* Nope, that didn't work
* oops send state key to GetMembership
* Don't generate stripped state in client API more times than necessary, generate output events on receiving end of federated invite
* Commit membership updater changes
* Tweaks
* Add a bit more logging to the fedsender
* bugfix: continue sending PDUs if ones are added whilst sending another PDU
Without this, the queue goes back to sleep on `<-oq.notifyPDUs` which won't
fire because `pendingPDUs` is already > 0. This should fix a flakey sytest.
* Break if no txn is sent
* WIP syncapi work
* More debugging
* Bump GMSL version to pull in working Event.Redact
* Remove logging
* Make redactions work on v3+
* Fix more tests
* Emit redacted_event from the roomserver when redactions are validated
- Consume them in the currentstateserver and act accordingly.
- Add integration test for the roomserver to check that injecting
`m.room.redaction` events result in `redacted_event` being emitted.
* Linting
* Ignore events that redact themselves
* Use content_value instead of membership
* Fix build
* Replace publicroomsapi with a combination of clientapi/roomserver/currentstateserver
- All public rooms paths are now handled by clientapi
- Requests to (un)publish rooms are sent to the roomserver via `PerformPublish`
which are stored in a new `published_table.go`
- Requests for public rooms are handled in clientapi by:
* Fetch all room IDs which are published using `QueryPublishedRooms` on the roomserver.
* Apply pagination parameters to the slice.
* Do a `QueryBulkStateContent` request to the currentstateserver to pull out
required state event *content* (not entire events).
* Aggregate and return the chunk.
Mostly but not fully implemented (DB queries on currentstateserver are missing)
* Fix pq query
* Make postgres work
* Make sqlite work
* Fix tests
* Unbreak pagination tests
* Linting
* Return remote errors from FS.PerformJoin
Follows the same pattern as PerformJoin on roomserver (no error return).
Also return the right format for incompatible room version errors.
Makes a bunch of tests pass!
* Handle network errors better when returning remote HTTP errors
* Linting
* Fix tests
* Update whitelist, pass network errors through in API=1 mode
* Add PerformInvite and refactor how errors get handled
- Rename `JoinError` to `PerformError`
- Remove `error` from the API function signature entirely. This forces
errors to be bundled into `PerformError` which makes it easier for callers
to detect and handle errors. On network errors, HTTP clients will make a
`PerformError`.
* Unbreak everything; thanks Go!
* Send back JSONResponse according to the PerformError
* Update federation invite code too
* Pass join errors through internal API boundaries
Required for certain invite sytests. We will need to think of a
better way of handling this going forwards.
* Include m.room.avatar in stripped state; handle trailing slashes when GETing state events
* Update whitelist
* Update whitelist
* Minor perf/debugging improvements
- publicroomsapi: Don't call QueryEventsByID with no event IDs
- appservice: Consume only if there are 1 or more ASes
- roomserver: don't keep a copy of the request "for debugging" - we trace now
* fedsender: return early if we have no destinations
* Unbreak tests
This is a wrapper around whatever impl we have which then logs
the function name/request/response/error.
Also tweak when we log on kafka streams: only log on the producer
side not the consumer side: we've never had issues with comms and
having 1 message rather than N would be nice.
