* 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
* Use cumulative state IDs for final event
* Error wrapping in calculateAndSetState
* Handle overwriting same event type and state key
* Hacky way to spot historical events
* Don't exclude from sync
* Don't generate output events when rewriting forward extremities
* Update output event check
* Historical output events
* Define output room event type
* Notify key changes on state
* Don't send our membership event twice
* Deduplicate state entries
* Tweaks
* Remove unnecessary nolint
* Fix current state upsert in sync API
* Send auth events as outliers, state events as rewrite
* Sync API don't consume state events
* Process events actually
* Improve outlier check
* Fix local room check
* Remove extra room check, it seems to break the whole damn world
* Fix federated join check
* Fix nil pointer exception
* Better comments on DeduplicateStateEntries
* Reflow forced federated joins
* Don't force federated join for possibly even local invites
* Comment SendEventWithState better
* Rewrite room state in sync API storage
* Add TODO
* Clean up all room data when receiving create event
* Don't generate output events for rewrites, but instead notify that state is rewritten on the final new event
* Rename to PurgeRoom
* Exclude backfilled messages from /sync
* Split out rewriting state from updating state from state res

* 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
* Use federation sender for backfill and getting missing events
* Fix internal URL paths
* Update go.mod/go.sum for matrix-org/gomatrixserverlib#218
* Add missing server implementations in HTTP interface
* Initial pass at refactoring config (not finished)
* Don't forget current state and EDU servers
* More shifting around
* Update server key API tests
* Fix roomserver test
* Fix more tests
* Further tweaks
* Fix current state server test (sort of)
* Maybe fix appservices
* Fix client API test
* Include database connection string in database options
* Fix sync API build
* Update config test
* Fix unit tests
* Fix federation sender build
* Fix gobind build
* Set Listen address for all services in HTTP monolith mode
* Validate config, reinstate appservice derived in directory, tweaks
* Tweak federation API test
* Set MaxOpenConnections/MaxIdleConnections to previous values
* Update generate-config
* 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
