Port tg.url() to TG2

Port the tg.url function to tg2. The origonal can be found at:

source:/branches/1.0/turbogears/controllers.py line 477

I guess new impl. should be using WebOb?, http://pythonpaste.org/webob/#urls?

got stuck. I'm writing a unit test and I need a way to setup pylons.request so that I can test the url().

give up.

I implemented a create_request() function so that url() can tested easily. But it seems to me that re-writing it to work with newer webob yet be compatible with TG1 would take too much time. And it's not clear whether its worth it. I move on to other things, feel free to pick the ticket up.

P.S.: My "naive" code looked like this:

def url(tgpath, tgparams=None, **kw):
    from tg import request
    if not isinstance(tgpath, basestring):
        tgpath = "/".join(list(tgpath))
    path = request.relative_url(tgpath)
    base_url = request.path_url
    return path[len(base_url):]

def test_url():
    create_request('/')
    eq_('hello', url('hello'))
    eq_('/hello', url('/hello'))

commited my code in t3876, just in case.

Will start by porting TG1 unit tests.

Giving up, too. Looking at url() in TG1, redirect() could share code with url().

I have attached a patch against rev 3887. It contains incomplete work, including unit tests ported from TG1.

The TG portion of this is fixed, waiting on some changes in webob.
