Since all controller instances are required to have a request and
response object, RackDelegation is no longer needed (we always have to
delegate to the response)
The controller instance always has an instance of a response object. We
should store the status code on the response object so that it's only
store in one place.
Controllers should always have a request and response when responding.
Since we make this The Rule(tm), then controllers don't need to be
somewhere in limbo between "asking a response object for a rack
response" or "I, myself contain a rack response". This duality leads to
conditionals spread through the codebase that we can delete:
* 85a78d9358/actionpack/lib/action_controller/metal.rb (L221-L223)
people should be accessing request information through the request
object, not via the env hash. If they really really want at the env
hash, then they can get it off the request.
Actions are processed through `dispatch`, so they should have the
request set on them before any user land code can be executed. Lets
stop setting _env on the controller, and give access to it through the
`env` method.
We should do the hard work outside the constructor. Also fix the tests
to not directly construct middleware objects, but to go through the
stack object.
Commit 20fece1 introduced the `_status_code` method to fix calls to
`head :ok`. This method has been added on both ActionController::Metal
and ActionDispatch::Response.
As for the latter, this method is just equivalent to the `response_code`
one so commit aefec3c removed it from the `Reponse` object so call to
the `_status_code` method on an ActionController::Base instance would be
handled by the `Metal` class (which `Base` inherits from) but the status
code is not updated according to the response at this level.
The fix is to actually rely on `response_code` for ActionController::Base
instances but this method doesn't exist for bare Metal controllers so we
need to define it.
* constraints:
rm reset_parameters because we automatically do it from 9ca4839a
move path_parameter encoding check to the request object
dispatcher doesn't need `call` anymore
call `serve` with the request on dispatchers
constraints class does not need the request class anymore
give all endpoints a superclass
skip the build business if the stack is empty
stop hardcoding path_parameters and get it from the request
we do not need to cache rack_app
a redirect is not a dispatcher by definition, so eliminate test
push is_a check up to where the Constraints object is allocated
pass the request object to the application
pass a request to `matches?` so we can avoid creating excess requests
nothing is passed to `rack_app` anymore, so rm the params
one fewer is_a check
Constraints#app should never return another Constraints object, so switch to if statement
eliminate dispatcher is_a checks
push is_a?(Dispatcher) check in to one place
Always construct route objects with Constraint objects
