2022-11-15Federation fixes for virtual hostingNeil Alexander
2022-10-26Initial support for multiple server names (#2829)Neil Alexander
This PR is the first step towards virtual hosting by laying the groundwork for multiple server names being configured.
2022-10-07Fix issue with DMs shown as normal rooms (#2776)Till
Fixes #2121, test added in https://github.com/matrix-org/complement/pull/494
2022-10-04Don't perform a federated join after invite if we are already joined to the ↵Neil Alexander
room (#2762) If we are already joined to the room then it shouldn't matter if you were invited or not, so this looks like a bug.
2022-08-11Generic-based internal HTTP API (#2626)Neil Alexander
* Generic-based internal HTTP API (tested out on a few endpoints in the federation API) * Add `PerformInvite` * More tweaks * Fix metric name * Fix LookupStateIDs * Lots of changes to clients * Some serverside stuff * Some error handling * Use paths as metric names * Revert "Use paths as metric names" This reverts commit a9323a6a343f5ce6461a2e5bd570fe06465f1b15. * Namespace metric names * Remove duplicate entry * Remove another duplicate entry * Tweak error handling * Some more tweaks * Update error behaviour * Some more error tweaking * Fix API path for `PerformDeleteKeys` * Fix another path * Tweak federation client proxying * Fix another path * Don't return typed nils * Some more tweaks, not that it makes any difference * Tweak federation client proxying * Maybe fix the key backup test

2022-05-25Restricted join support on `/make_join`, `/send_join` (#2478)Neil Alexander
* Add `QueryRestrictedJoinAllowed` * Add `Resident` flag to `QueryRestrictedJoinAllowedResponse` * Check restricted joins on federation API * Return `Restricted` to determine if the room was restricted or not * Populate `AuthorisedVia` properly * Sign the event on `/send_join`, return it in the `/send_join` response in the `"event"` key * Kick back joins with invalid authorising user IDs, use event from `"event"` key if returned in `RespSendJoin` * Use invite helper in `QueryRestrictedJoinAllowed` * Only use users with the power to invite, change error bubbling a bit * Placate the almighty linter One day I will nuke `gocyclo` from orbit and everything in the world will be much better for it. * Review comments
2022-05-05Define component interfaces based on consumers (2/2) (#2425)kegsay
* convert remaining interfaces * Tidy up the userapi interfaces
2022-02-21Return `ErrRoomNoExists` if insufficient state is available for a ↵Neil Alexander
`buildEvent` to succeed when joining a room (#2210) This may help cases like #2206, since it should prompt us to try a federated join again instead.

2020-09-29Fetch missing auth events, implement QueryMissingAuthPrevEvents, try other ↵Neil Alexander
servers in room for /event and /get_missing_events (#1450) * Try to ask other servers in the room for missing events if the origin won't provide them * Logging * More logging * Implement QueryMissingAuthPrevEvents * Try to get missing auth events badly * Use processEvent * Logging * Update QueryMissingAuthPrevEvents * Try to find missing auth events * Patchy fix for test * Logging tweaks * Send auth events as outliers * Update check in QueryMissingAuthPrevEvents * Error responses * More return codes * Don't return error on reject/soft-fail since it was ultimately handled * More tweaks * More error tweaks
2020-09-16Implement rejected events (#1426)Kegsay
* 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
2020-09-15Handle state with input event as new events (#1415)Neil Alexander

2020-09-02Add Queryer and Inputer and factor out more RSAPI stuff (#1382)Kegsay
* 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.
2020-09-02Refactor roomserver/internal - split perform stuff out (#1380)Kegsay
- New package `perform` which contains all `Perform` functions - New package `helpers` which contains helper functions used by both perform and query/input functions. - Perform invite/leave have no idea how to `WriteOutputEvents` and this is now returned from `PerformInvite` or `PerformLeave` respectively. Still to do: - RSAPI is fed into the inviter/joiner/leaver - this introduces circular logic so will need to be removed. - Put query operations in a `query` package. - Put input operations (and output) in an `input` package. - Factor out helper functions as much as possible, possibly rejigging the storage layer in the process.
