Arguments: port (name t) arg &rest keys &allow-other-keys
This function is called each time a remote request, sent with rpc-send-request, is executed at the receiving end.
The default method simply returns 0.
We provide two methods that implement the behavior of the with-rpc-port-enabler mixin
class. An application can define methods on subclasses of rpc-port to control access to
the port in other ways.
This method signals an error unless the port has been enabled with a :enable-client request with an appropriate passcode.
This is a :around method to ensure that the method body is called before any primary methods, regardless of the class precendence list. The application may define a primary method to add other filtering algorithms.
This method tests the arg argument against the passcode defined in the port.
If the server was defined with a :passcode value that is an atom, then the :tester function is called with arg and passcode. If the function returns a non-nil value, the port is enable for subsequent requests and remote calls.
If the port was defined with a :passcode value that is a list, then arg is matched with the member function against the list with tester as the test function. If arg is found in the list, the port is enabled, and the matching passcode is removed from the server list.
