> [repurposing this bug as refactoring-only]
> Joey Schorr and I have created the attached patch to features/rpc/rpc.js,
> which refactors rpc.js in various ways but changes no semantics. The goal is
> to make reading of the code more straightforward, and especially to clearly
> separate code paths that have to do with the various message passing
> transport mechanisms (frameElement, IFPC, WPM/DPM). This makes it easier to
> add new transports. It may also, in the future, enable us to serve only one
> transport class appropriate to a given browser on the server side, minimizing
> response size, but for now is just cleanup.
> Details:
> * Created constants for the default callback and callback service IDs
> * Added extensive documentation on each transport mechanism in the selection
> method getRelayChannel()
> * Created setupChannel(), setupFrame(), and callX() methods for
> transport-specific functionality.
> - setupChannel() performs global initialization of the transport
> - setupFrame() adds any setup associated with setting authToken on a frame
> - callX() methods perform actual message passing
> The attached patch (rpc.refactor.patch) is derived from an earlier, larger
> one that also included a new transport mechanism for IE only. That
> functionality will be moved to a new JIRA issue with a separate patch.
