Overview

A dumb fake web server. This is minimal object wrapper around Rack/WEBrick. WEBrick was chosen because it comes with ruby and we’re not doing rocket science here. Kim runs Rack/WEBrick in a separate thread and keeps an array of handlers. A handler is simply a predicate on a request object and a function to handle the request should the predicate return truthy. When rack notifies us of a request, we dispatch it to the first handler with a truthy predicate.

Again, what we’re trying to do is very simple. Most of the existing complexity is due to

  • thread synchronization

  • unmangling WEBrick’s header renaming

  • loosening the requirements on what a handler function must return

To support path parameters (e.g., /people/:name), a predicate may return a Request object as a truthy value, augmented with additional params. When the predicate returns a Request, the augmented request object is passed to the handler function in place of the original request.
