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.
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.
I'm going to need some more flexibility in handling login types in password
auth providers, so as a first step, move some stuff from LoginRestServlet into
AuthHandler.
In particular, we pass everything other than SAML, JWT and token logins down to
the AuthHandler, which now has responsibility for checking the login type and
fishing the password out of the login dictionary, as well as qualifying the
user_id if need be. Ideally SAML, JWT and token would go that way too, but
there's no real need for it right now and I'm trying to minimise impact.
This commit *should* be non-functional.
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.
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.
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.
This requires a bit of fettling, because I want to return a helpful error
message too but we don't want to distinguish between unknown user and invalid
password. To avoid hardcoding the error message into 15 places in the code,
I've had to refactor a few methods to return None instead of throwing.
Fixes https://matrix.org/jira/browse/SYN-744
Allows delegating the password auth to an external module. This also
moves the LDAP auth to using this system, allowing it to be removed from
the synapse tree entirely in the future.
