Re: [TurboGears] Re: New Version of Routes 1.12 makes everything 404

Hey Nicholas,

(thread sidetrack ahead:)
I've got a question about your first comment, that the latest TG2 is broken: what version of Python are you running? did you install to a new virtualenv? and do the tests fail, or is it just your application that breaks?
Diez was also having trouble with the latest tip, but he hasn't replied as to what environment he was using when the problems occurred.
I'm basically responsible for the latest changes in the repository, so I'd like to fix them, but everything works fine for me with a fresh virtualenv in python2.5.4. 

Thanks!

OMG I just found the same problem.
This was exceedingly difficult to diagnose.
Especially since I just pulled down TG2 like yesterday and it was
broken...

My diagnosis was something about environ['pylons.routes_dict']['url']
It use to remove the leading '/'.
Now it does not.

When TGController tries to property intercept __before__ and __after__
it uses the 'url' to find the right object controller in which to find
__before__.

ObjectDispatchController._get_routing_info() makes the assumption that
the url will not have a leading '/'

I am not sure whether this is routes that is changing a contract, or
the Controller which is making a foolish assumption.

Is there a bug I should add to?  Should I create a bug?

Hey, just had a horrible time debugging an issue, turns out the new
version of routes breaks something and causes all requests to 404 in
at least python 2.5 and 2.6 for tg2. We fixed this issue by going back 
to 1.11. Not sure if this will help but here is a sample trace.
