Currently the handling of auto_join_rooms only works when a user
registers itself via public register api. Registrations via
registration_shared_secret and ModuleApi do not work
This auto_joins the users in the registration handler which enables
the auto join feature for all 3 registration paths.
This is related to issue #2725

* [ ] fix docstring and move check_3pid_allowed into a new util module
* [ ] use check_3pid_allowed everywhere
@erikjohnston PTAL
Also move duplicated deactivation code into the auth handler.
I want to add some hooks when we deactivate an access token, so let's bring it
all in here so that there's somewhere to put it.
- 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.
The 'time' caveat on the access tokens was something of a lie, since we weren't
enforcing it; more pertinently its presence stops us ever adding useful time
caveats.
Let's move in the right direction by not lying in our caveats.
* `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.
The only place that was observed was to set the profile. I've made it
so that the profile is set within store.register in the same transaction
that creates the user.
This required some slight changes to the registration code for upgrading
guest users, since it previously relied on the distributor swallowing errors
if the profile already existed.
Move the functions inside the distributor and import them
where needed. This reduces duplication and makes it possible
for flake8 to detect when the functions aren't used in a
given file.
This means that following the same link across multiple sessions or
devices can re-use the same guest account.
Note that this is somewhat of an abuse vector; we can't throw up
captchas on this flow, so this is a way of registering ephemeral
accounts for spam, whose sign-up we don't rate limit.
The current random IDs are ugly and confusing when presented in UIs.
This makes them prettier and easier to read.
Also, disable non-automated registration of numeric IDs so that we don't
need to worry so much about people carving out our automated address
space and us needing to keep retrying ID registration.
