* Change account and user fabricators to simplify and improve tests
- `Fabricate(:account)` implicitly fabricates an associated `user` if
no `domain` attribute is given (an account with `domain: nil` is
considered a local account, but no user record was created), unless
`user: nil` is passed
- `Fabricate(:account, user: Fabricate(:user))` should still be possible
but is discouraged.
* Fix and refactor tests
- avoid passing unneeded attributes to `Fabricate(:user)` or
`Fabricate(:account)`
- avoid embedding `Fabricate(:user)` into a `Fabricate(:account)` or the other
way around
- prefer `Fabricate(:user, account_attributes: …)` to
`Fabricate(:user, account: Fabricate(:account, …)`
- also, some tests were using remote accounts with local user records, which is
not representative of production code.
Allow access to account settings, 2FA, authorized applications, and
account deletions to unconfirmed and pending users, as well as
users who had their accounts disabled. Suspended users cannot update
their e-mail or password or delete their account.
Display account status on account settings page, for example, when
an account is frozen, limited, unconfirmed or pending review.
After sign up, login users straight away and show a simple page that
tells them the status of their account with links to account settings
and logout, to reduce onboarding friction and allow users to correct
wrongly typed e-mail addresses.
Move the final sign-up step of SSO integrations to be the same
as above to reduce code duplication.
* Do not raise unretryable exceptions in ResolveRemoteAccountService
* Removed fatal exceptions from ResolveRemoteAccountService
Exceptions that cannot be retried should not be raised. New exception
class for those that can be retried (Mastodon::UnexpectedResponseError)
* Move ApiController to Api/BaseController
* API controllers inherit from Api::BaseController
* Add coverage for various error cases in api/base controller
