I'm going to need to make the device_handler depend on the auth_handler, so I
need to break this dependency to avoid a cycle.
It turns out that the auth_handler was only using the device_handler in one
place which was an edge case which we can more elegantly handle by throwing an
error rather than fixing it up.
- GET is now the method for register/available
- a query parameter "username" is now used
Also, empty usernames are now handled with an error message on registration or via register/available: `User ID cannot be empty`
This was broken when device list updates were implemented, as Mailer
could no longer instantiate an AuthHandler due to a dependency on
federation sending.
We might as well treat all refresh_tokens as invalid. Just return a 403 from
/tokenrefresh, so that we don't have a load of dead, untestable code hanging
around.
Still TODO: removing the table from the schema.
Since we're not doing refresh tokens any more, we should start killing off the
dead code paths. /tokenrefresh itself is a bit of a thornier subject, since
there might be apps out there using it, but we can at least not generate
refresh tokens on new logins.
Rather than reimplementing the token parsing in the various places.
This will make it easier to change the token parsing to allow access_tokens
in HTTP headers.
Synapse was not adding email addresses to accounts registered with an email address, due to too many different variables called 'result'. Rename both of them. Also remove the defer.returnValue() with no params because that's not a thing.
device_id may only be passed in the first call to /register, so make sure we
fish it out of the register `params` rather than the body of the final call.
This doesn't cover *all* of the registration flows, but it does cover the most
common ones: in particular: shared_secret registration, appservice
registration, and normal user/pass registration.
Pull device_id from the registration parameters. Register the device in the
devices table. Associate the device with the returned access and refresh
tokens. Profit.
* `RegistrationHandler.appservice_register` no longer issues an access token:
instead it is left for the caller to do it. (There are two of these, one in
`synapse/rest/client/v1/register.py`, which now simply calls
`AuthHandler.issue_access_token`, and the other in
`synapse/rest/client/v2_alpha/register.py`, which is covered below).
* In `synapse/rest/client/v2_alpha/register.py`, move the generation of
access_tokens into `_create_registration_details`. This means that the normal
flow no longer needs to call `AuthHandler.issue_access_token`; the
shared-secret flow can tell `RegistrationHandler.register` not to generate a
token; and the appservice flow continues to work despite the above change.
This is meant to be an *almost* non-functional change, with the exception that
it fixes what looks a lot like a bug in that it only calls
`auth_handler.add_threepid` and `add_pusher` once instead of three times.
The idea is to move the generation of the `access_token` out of
`registration_handler.register`, because `access_token`s now require a
device_id, and we only want to generate a device_id once registration has been
successful.
The spec is clear the key should be 'user' not 'username' and this is indeed
the case for v1. This is not true for v2_alpha though, which is what this
commit is fixing.
This follows the same flows-based flow as regular registration, but as
the only implemented flow has no requirements, it auto-succeeds. In the
future, other flows (e.g. captcha) may be required, so clients should
treat this like the regular registration flow choices.
* Merge LoginHandler -> AuthHandler
* Add a bunch of documentation
* Improve some naming
* Remove unused branches
I will start merging the actual logic of the two handlers shortly
V2 Registration forced everyone (including ASes) to create a password for a
user, when ASes should be able to omit passwords. Also unbreak AS registration
in general which checked too early if the given username was claimed by an AS;
it was checked before knowing if the AS was the one doing the registration! Add
unit tests for AS reg, user reg and disabled_registration flag.
* Now only the auth part goes to fallback, not the whole operation
* Auth fallback is a normal API endpoint, not a static page
* Params like the recaptcha pubkey can just live in the config
Involves a little engineering on JsonResource so its servlets aren't always forced to return JSON. I should document this more, in fact I'll do that now.
