Travis Ralston e60b44e27f Clean up PUT /directory/room
Fixes https://github.com/matrix-org/matrix-doc/issues/933

The issue references two problems: a `roomInfo` and lack of a `room_id`. It appears the `room_id` has been fixed since reporting, however the `roomInfo` remained (and is now fixed).

Travis Ralston 55c0b968b5 Fix event schemas for /sync
This commit clarifies the required keys for each type of event that appears in sync, fixes the core event schema not declaring 'content' as required, and includes a mention that events may not have a room_id when appearing in /sync.

Travis Ralston 1bc0f63bfb Clarify the homeserver's behaviour for user searching
The homeserver can implement its own algorithm, but is suggested to ensure the requesting user can reasonably see the other users.

The text is intentionally left vague for whether or not the API is local users only to give the homeserver some flexibility in this area.

General cleanup is also included in this commit.

Travis Ralston 7ec3cc4343 General improvements to the push rules module
This commit does a few things:
* Add 3 undocumented push rules to the spec for encrypted events and at-room notifications.
* Require unrecognized conditions to not match, ensuring that future conditions do not cause clients to accidentally notify users.
* Clarify that push rules should be enabled when created.
* Document a new condition required for at-room notifications.

Travis Ralston 45c68e323a Add general clarity to the /createRoom endpoint
This commit does a number of things:
* Minor formatting/alignment changes
* Document the room_alias response key. This could be deprecated now, or forfeited, if needed.
* Remove the guest_can_join parameter - it is not actually supported
* Document the previously undocumented power_level_content_override parameter
* Clarify that the room_id is required on the response
* More clearly spell out which events are created as part of the request
* Clarify how the room alias becomes the canonical alias
* Clarify how the `visibility` may be used to determine a default preset to apply
* Document the `m.federate` creation content parameter, adding an option for the homeserver to define a default value

References:
* Preset being inferred by the visibility: cd32c19a60/synapse/handlers/room.py (L172-L177)

Room version upgrades are not part of MSC1425.

* room_version on the create event
* creating a room with a specific version (useful for testing)
* make_join behaviour
* error code documentation
* grammar of room versions

Travis Ralston 6ad71f785e Improve documentation for pushers and push gateways
This fixes a number of formatting issues alongside a few documentation problems:
* The push gateway can actually expect less parameters than previously advertised. This is for user privacy.
* Introduction of the `m.email` pusher for email-capable homeservers.
* Fields not being flagged as required on some endpoints.
* Document the `event_id_only` format

Note: this does not attempt to document push rules, just pushers.

Travis Ralston 88b35d1be5 Clarify how third party invites work
This adds several diagrams to the Client-Server API about how invites
are handled, including what the server is expected to do. This helps
implementors know what they are supposed to do in the common cases,
and infer where needed to get the more complex cases correct.

Although lacking in some areas, this is how third party invites work
today.

A link to the now-improved client-server documentation for third party
invites has been added to the server-server specification. The existing
server-server specification needed no further changes on the subject.

Travis Ralston 05a2427c73 Document how presence EDUs work between servers
It's worth noting that Synapse does not make use of the `poll` or `unpoll` fields, and therefore the wording has been updated to permit servers to reject users. In the case of synapse, it would automatically reject everyone in the list by nature of ignoring it.

This intentionally doesn't document the third party network aspect of the endpoint. This is scheduled for a later area for dealing with third party network/IDs and is reported as https://github.com/matrix-org/matrix-doc/issues/1476

The client-server response has been broken out to a shared file: both the client-server and server-server /publicRoom endpoints return the same thing, with slightly different inputs.

The inputs (and behaviour) are based upon the docstring here: 43ecfe0b10/synapse/federation/transport/server.py (L583-L612)
6 years ago
Travis Ralston 73958ecbff Document /event_auth and /query_auth
/event_auth is a fairly easy endpoint to determine the use case of. /query_auth is a little harder to investigate and has a fairly interesting purpose: it appears to be used for the sending server to admit defeat and shop around for the right auth chain, correcting it's own perspective as it goes.

/query_auth is based off the following research points in synapse:
* 43ecfe0b10/synapse/handlers/federation.py (L1947-L1990)
* 43ecfe0b10/synapse/handlers/federation.py (L2049-L2187)

Travis Ralston 9fdd8a6f96 Document how leaving rooms/rejecting invites over federation works
Fixes https://github.com/matrix-org/matrix-doc/issues/1401

This is very similar to the joining rooms handshake, and much of it is a near copy/paste of the make_join and send_join API. The major difference is the send_leave API doesn't return anything.

References:
* Handling of make_leave: d69decd5c7/synapse/handlers/federation.py (L1285-L1310)
* send_leave route: d69decd5c7/synapse/federation/transport/client.py (L267)
* make_leave route: d69decd5c7/synapse/federation/transport/server.py (L396)
* send_leave returning nothing: d69decd5c7/synapse/handlers/federation.py (L1346)
