Correctly pass the multiple parameters to the cubicweb request When naively converted to a dict, the webob MultiDict will not set the multiple parameters (a same name with several values) in a way CW can understand. MultiDict.mixed() however, does exactly what CW needs: list values for keys with multiple values, and single value for the others. Related to #4291181

Add a wsgi application factory suitable for wsgi servers. This factory can generate a wsgi application for a cubicweb instance. It reads the instance name from the CW_INSTANCE environment variable, and activates the debugmode if CW_DEBUG is defined in environment. It is usable by uwsgi as the 'module' parameter : CW_INSTANCE=test uwsgi --plugins python,http --http 0.0.0.0:8080 --module pyramid_cubicweb:wsgi_application()

Use registry['cubicweb.registry'] instead of registry['cubicweb.appli'].vreg because the application may not be present. Related to #4291173

Use a predicate based view selection for handling /login This will allow easy addition of login handlers from the application or cubes Related to #4291173

Use a tween application instead of a catchall route. Using a catchall route has some drawbacks. Especially, we have no mean to have a route that would match only if no other one does AND no view matches either. Said differently, our default handler cannot be plugged on the route level nor the view level, because it is has to be activated only if nothing else works in the pyramid application. Using a tween application allow to handle requests that raises a HTTPNotFound error, while having the pyramid error handler still active between our tween app and the outside world.
