* WIP: Eagerly sync device lists on /user/keys/query requests
Also notify servers when a user's device display name changes. Few
caveats:
- sytest `Device deletion propagates over federation` fails
- `populateResponseWithDeviceKeysFromDatabase` is called from multiple
goroutines and hence is unsafe.
* Handle deleted devices correctly over federation
* Fix New users appear in /keys/changes
* Create blank device keys when logging in on a new device
* Add PerformDeviceUpdate and fix a few bugs
- Correct device deletion query on sqlite
- Return no keys on /keys/query rather than an empty key
* Unbreak sqlite properly
* Use a real DB for currentstateserver integration tests
* Race fix
* Recheck device lists when join/leave events come in
* Add PerformDeviceDeletion
* Notify clients when devices are deleted
* Unbreak things
* Remove debug logging
* User directory
* Fix syncapi unit test
* Make user directory only show remote users you know about from your joined rooms
* Update sytest-whitelist
* Review comments
* BREAKING: Make eduserver/appservice use userapi
This is a breaking change because this PR restructures how the AS API
tracks its position in Kafka streams. Previously, it used the account DB
to store partition offsets. However, this is also being used by `clientapi`
for the same purpose, which is bad (each component needs to store offsets
independently or else you might lose messages across restarts). This PR
changes this behaviour to now store partition offsets in the `appservice`
database.
This means that:
- Upon restart, the `appservice` component will attempt to replay all
room events from the beginning of time.
- An additional table will be created in the appservice database, which
in and of itself is backwards compatible.
* Return ErrorConflict
* Make userapi responsible for checking access tokens
There's still plenty of dependencies on account/device DBs, but this
is a start. This is a breaking change as it adds a required config
value `listen.user_api`.
* Cleanup
* Review comments and test fix
