Adds gitlab.impersonation_enabled config option defaulting to true to
keep the current default behaviour.
Only the act of impersonation is modified, impersonation token
management is not affected.
- Use a struct for scopes, so we can call `scope.if` instead of `scope[:if]`
- Refactor the "remove scopes whose :if condition returns false" logic to use a
`select` rather than a `reject`.
1. Get the spec for `lib/gitlab/auth.rb` passing.
- Make the `request` argument to `AccessTokenValidationService` optional -
`auth.rb` doesn't need to pass in a request.
- Pass in scopes in the format `[{ name: 'api' }]` rather than `['api']`, which
is what `AccessTokenValidationService` now expects.
2. Get the spec for `API::V3::Users` passing
2. Get the spec for `AccessTokenValidationService` passing
- Scope declarations of the form:
allow_access_with_scope :read_user, if: -> (request) { request.get? }
will only apply for `GET` requests
- Add a negative test to a `POST` endpoint in the `users` API to test this. Also
test for this case in the `AccessTokenValidationService` unit tests.
- Declaring an endpoint's scopes in a `before` block has proved to be
unreliable. For example, if we're accessing the `API::Users` endpoint - code
in a `before` block in `API::API` wouldn't be able to see the scopes set in
`API::Users` since the `API::API` `before` block runs first.
- This commit moves these declarations to the class level, since they don't need
to change once set.
- Previously, AccessTokenValidationService was a module, and all its public
methods accepted a token. It makes sense to convert it to a class which accepts
a token during initialization.
- Also rename the `sufficient_scope?` method to `include_any_scope?`
- Based on feedback from @rymai
- Move the `Oauth2::AccessTokenValidationService` class to
`AccessTokenValidationService`, since it is now being used for
personal access token validation as well.
- Each API endpoint declares the scopes it accepts (if any). Currently,
the top level API module declares the `api` scope, and the `Users` API
module declares the `read_user` scope (for GET requests).
- Move the `find_user_by_private_token` from the API `Helpers` module to
the `APIGuard` module, to avoid littering `Helpers` with more
auth-related methods to support `find_user_by_private_token`
