hrm, what do other ppl on the dev team think about this? In particular:

is removing shared-secret support from /client/r0/register going to break things for people? It's worth noting that the docs don't say anything about it being available on the /client/r0/register endpoint.
if we add an admin API for registering users as an admin user rather than via a shared secret, should it go on a different endpoint to the existing api or is it ok to share?

@awesome-manuel: note that the admin api endpoints are documented at https://github.com/matrix-org/synapse/blob/master/docs/admin_api/ so as part of this change, that documentation will need updating.

awesome-manuel · 2019-07-23T13:52:08Z

@richvdh also note that the checks in _synapse/admin/v1/register are more strict than in /client/r0/register, e.g. no space allowed in username or password and max length must be lower than 512 characters.

@awesome-manuel: thanks for this. I think our position on this is:

removing support for shared-secret registration from /client/r0/register is fine, but needs calling out as a specific point in the changelog (so it needs a .removal file in changelog.d). Ideally it would be a separate PR, but I won't insist on that.
We'd rather support for registration-as-admin ended up on a separate REST endpoint in /admin to shared-secret-registration.

awesome-manuel · 2019-07-30T10:17:31Z

@richvdh any suggestion how this new endpoint should be called?

richvdh · 2019-07-30T15:28:30Z

I suggest something like create_user. The existing register name is poor, but that is something to fix another time.

@richvdh see #5877

What do you think of a POST on _synapse/admin/v1/users? Seems to be more REST-like.

Sure, that could work.

This parameter was used to test if the homeserver belongs to this user_id. Now the requesting user is tested instead. Not sure if this is required, since the request must be an admin anyway.

Partly fixes #2522, but should be done in a separate PR.

Looks like a great improvement, thanks! A few comments though...

Hrm. Can you make this continue to accept (but ignore) a /user_id, for compatibility with applications which have hacked around the existing broken API?

This is redundant. The requester is a local user by definition.

shouldn't be an empty object afaict. (Indeed, your test even asserts that.)

this will issue an access token for the user, which I'm not sure is the right thing to do. (even if you do want to end up with an access token for the new user, I think that might be better served via a different API per #6054).

In short, I don't think you need to call _create_registration_details here, which is good since it's meant to be a private method and instantiating a RegisterRestServlet here is ugly.

there are better ways of getting hold of the registration_handler than via the RegisterRestServlet. Just stick
self.registration_handler = hs.get_registration_handler() in the constructor.
