capture uwsgi start_response

[Emanuel Vitorino]

Hi all

I'm making some changes in an old application that uses trac edgewall, being my first interaction with trac and CherryPy


The thing is, the application that is on production now is something like this:

wsgi.py

def application(environ, start_response):

     if something():  # this is just an example

         start_response('301 Moved Permanently', [('Location', 'http://google.com')])

         return []

    else:

        return trac.web.main.dispatch_request(environ, start_response)

trac.web.main.dispatch_request is the trac wsgi application

But now, I need to put a cherrypy application in the middle so:

def application(environ, start_response):
    root = Trac()
    root.openid = Auth()
    cherrypy.tree.mount(root, "/", config=conf)
    return cherrypy.tree(environ, start_response)

And this works until the part that I must gave control to trac.web.main.dispatch_request
Inside cherrypy objects I cannot find start_response callback

And doing something like:

env = None

sr = None

class Trac():

    @cherrypy.expose

    def index(self):

         return trac.web.main.dispatch_request(env, sr)

def application(environ, start_response):

    env = environ

    sr = start_response
    root = Trac()

    root.openid = Auth()
    cherrypy.tree.mount(root, "/", config=conf)
    return cherrypy.tree(environ, start_response)

Also don't work throwing an error that response headers already been started.

Any ideas how to I can capture start_response inside my CP application

Thank you in advance

Kind regards,

Emanuel

Why don't you just mount Trac's WSGI app in the tree under some dedicated URL?

Hi

Thanks for your answer.

I've tried but still don't work.

I receive:

return child[key]
TypeError: 'Response' object does not support indexing

Any other idea? :)

Thanks,

Emanuel
