Explanation / Answer

4) has visited all the vertices that it can reach

When a user requests a page from your traversal -powered application, the system uses this algorithm to find a context and a view name.

The request for the page is presented to the repoze.bfg router in terms of a standard WSGI request, which is represented by a WSGI environment and a WSGI start_response callable.

The router creates a request object based on the WSGI environment.

The root factory is called with the request. It returns a root object.

The router uses the WSGI environment
