Closes: #9941

Required some fixes due to merge conflicts with #6739, but nothing too hairy. The first commit is the same as the original (after merge conflict resolution) then two more for compatibility with the latest sync code.

This leaves out all optional keys from /sync. This should be fine for all clients tested against conduit already, but it may break some clients, as such we should check, that at least most of them don't break horribly and maybe back out some of the individual changes. (We can probably always leave out groups for example, while the others may cause more issues.)

erdnaxeli commented Jul 23, 2021

I just want you to notice that this change can break lib (it broke mine) 😬

Actually the spec is not helpfull to know which fields will always be there and which are optional. Sometimes the field is required and this is specified, like in the response of /login:

m.homeserver | Homeserver Information | Required. Used by clients to discover homeserver information.

Sometimes the field is optional and this is specified, like in the description on UnsignedData:

redacted_because | Event | Optional. The event that redacted this event, if any.

But often there is just nothing, and we don't know. The specs should specify at the start of the document a default behavior, and then remove the useless precision ("required" or "optional", depending on the default).

All fields in /sync are optional, except next_batch, it's just that synapse has always returned them by default.

Well, as I was saying, the spec does not make it clear.
