Federation for v3/v4 rooms (#954)
* Update gomatrixserverlib * Default to room version 4 * Update gomatrixserverlib * Limit prev_events and auth_events * Fix auth_events, prev_events * Fix linter issues * Update gomatrixserverlib * Fix getState * Update sytest-whitelist * Squashed commit of the following: commit067b875063Author: Neil Alexander <neilalexander@users.noreply.github.com> Date: Fri Apr 3 14:29:06 2020 +0100 Invites v2 endpoint (#952) * Start converting v1 invite endpoint to v2 * Update gomatrixserverlib * Early federationsender code for sending invites * Sending invites sorta happens now * Populate invite request with stripped state * Remodel a bit, don't reflect received invites * Handle invite_room_state * Handle room versions a bit better * Update gomatrixserverlib * Tweak order in destinationQueue.next * Revert check in processMessage * Tweak federation sender destination queue code a bit * Add comments commit955244c092Author: Ben B <benne@klimlive.de> Date: Fri Apr 3 12:40:50 2020 +0200 use custom http client instead of the http DefaultClient (#823) This commit replaces the default client from the http lib with a custom one. The previously used default client doesn't come with a timeout. This could cause unwanted locks. That solution chosen here creates a http client in the base component dendrite with a constant timeout of 30 seconds. If it should be necessary to overwrite this, we could include the timeout in the dendrite configuration. Here it would be a good idea to extend the type "Address" by a timeout and create an http client for each service. Closes #820 Signed-off-by: Benedikt Bongartz <benne@klimlive.de> Co-authored-by: Kegsay <kegan@matrix.org> * Update sytest-whitelist, sytest-blacklist * Update go.mod/go.sum * Add some error wrapping for debug * Add a NOTSPEC to common/events.go * Perform state resolution at send_join * Set default room version to v2 again * Tweak GetCapabilities * Add comments to ResolveConflictsAdhoc * Update sytest-blacklist * go mod tidy * Update sytest-whitelist, sytest-blacklist * Update versions * Updates from review comments * Update sytest-blacklist, sytest-whitelist * Check room versions compatible at make_join, add some comments, update gomatrixserverlib, other tweaks * Set default room version back to v2 * Update gomatrixserverlib, sytest-whitelist
