Impossibility to mount a Sinatra app

Reported by Damien MATHIEU | April 26th, 2010 @ 12:54 PM | in 3.0.2

It's currently impossible to mount any Sinatra application on rails3.
The route is recognized by the rake routes command. But whenever we go to it in the browser or we execute it in the tests, we get a ActionController::RoutingError exception.

I've written a test case that reproduces it (but as I didn't succeed to reproduce it without Sinatra, it includes the framework. So it's not committable to rails).

A few days ago, I posted about it in Rails: Core. Mislav has already given some suppositions about it.

    • Tag changed from “rack, rack-mount, rails3, routes, sinatra” to “feature_request, rack, rack-mount, rails3, routes, sinatra”

    Rizwan Reza has published a repository showing that in fact, it works : http://github.com/rizwanreza/sinatra-rails
    Indeed, like that, it does.

    So I guess that's not really a bug but an improvement.
    In Rizwan's example, the Sinatra app is mounted in the "/sinatra" directory. And it does gets on /.
    This requires any Sinatra mounted application to be aware of the directory in which it'll be mounted. And if we change this directory, we need to also change all the routes in the sinatra app.

    Moreover, it forbids us to mount external apps without updating them.
    For example if I wanted to mount the resque's web app in the "/resque" directory, I couldn't without updating the sinatra app in the gem.

    • Milestone cleared.
    • State changed from “new” to “invalid”

    Damien, this is actually a Sinatra bug. According to the rack specification, env["PATH_INFO"] could be an empty string but Sinatra is not behaving properly when it sees one.

    Please see this issue: http://github.com/sinatra/sinatra/issues#issue/13

    Have you tried with other routes? I have a sinatra app working here with Rails 3 without problems (except by the ones related in that other ticket)!
