* 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
* Flesh out testing
* Flesh out walkThread a bit
* Persist the origin_server_ts as well
* Edges table instead of relationships
* Add nodes table for event metadata
* LEFT JOIN to extract origin_server_ts for children
* Add graph walking structs
* Implement walking algorithm
* Add more graph walking tests
* Add auto_join for local rooms
* Fix create table syntax on postgres
* Add relationship_room_id|servers to the unsigned section of events
* Persist the parent room_id/servers in edge metadata
Other events cannot assert the true room_id/servers for the
parent event, only make claims to them, hence why this is
edge metadata.
* guts to pass through room_id/servers
* Refactor msc2836 to allow handling from federation
* Add JoinedVia to PerformJoin responses
* Fix tests; review comments
* Add configuration for max_message_bytes for sarama
* Log all errors when sending multiple messages
Signed-off-by: Till Faelligen <tfaelligen@gmail.com>
* Add missing config
* - Better comments on what MaxMessageBytes is used for
- Also sets the size the consumer may use
* 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
* 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
* Add Queryer and use embedded structs
* Add Inputer and factor out more RS API stuff
This neatly splits up the RS API based on the functionality it provides,
whilst providing a useful place for code sharing via the `helpers` package.
