Fwd: webapp2 capability

[Stuart Mitchell-3]

Hi I am writing a google appengine service and I want to use pyamf

with the python27 runtime webapp has been upgraded to webapp2.
pyamf does not seem to work with this setup and I get the following error

Traceback (most recent call last):
  File "/home/stuart/hg/mw_appengine/google_appengine/google/appengine/runtime/wsgi.py",
line 175, in Handle
    for chunk in result:
TypeError: 'WebAppGateway' object is not iterable

I'm not sure if this is a problem with passing a object not a class to
the WSGIapplication or something todo with the
webapp.RequestHandler.initialize() method.

Has anyone got this working?

Stu
P.S. I have the it working with python25, but I can even install
python25 on my ubuntu 11.04 computer to test locally

I am using WSGIGateway with python27 on appengine without issue, haven't tried integrating with webapp2 yet.

I'll open a ticket to add support for this.

Thanks!

Yes I thought this may be a way to go but I have had to use it under
webapp2 as I want to have the gateway at a particular route. I Assume
the WSGIGateway only works on the root '\'.

We have been using pyAMF for a while now and would like to offer a
bounty / donation of $500USD

As you don't have a donation link how should we do this?

Also is it possible to integrate pyAMF with a testing framework? I am
using nose-gae but the only examples I see of testing actually involve
starting the dev_server, instead accessing the route within the tests.

Thanks
Stu

I have added support for webapp2 in the webapp2-gateway on my fork of pyamf - https://github.com/njoyce/github

I have tested the changes locally and everything appears to work correctly but I need to get the pyamf-appengine buildslave updated with the new 1.6 SDK before confirming.

Wow - very generous! Let's make sure the changes are working first ;)

It depends on what you're trying to test. If you're trying to test services, I suggest mocking the request object and calling the functions/methods directly, skipping the whole AMF layer entirely.

If you're looking to build integration tests then I would check https://gist.github.com/1407388 which builds a PyAMF Gateway and sends an AMF remoting request and decodes the response. Note that this snippet uses the excellent WebTest from Ian Bicking - http://pypi.python.org/pypi/WebTest

Cheers,

Nick

Yup this is what I am currently doing, will have to do some
integration tests though I expect.

I do not think google appengine run with python 2.7.

I think you actually meant https://github.com/njoyce/pyamf/tree/webapp2-gateway

Seems to work on dev-appengine but will confirm when I upload.

One point though as this is on appengine I previously downloaded the
zip and copied the code in the pyamf folder (underneath setup.py etc)
into my repository. This works fine from the pypi download but for the
git clone I need a _version.py file that is created by setup.py right?

Unfortunately, the given code uses webapp not webapp2 to build the app

def makeApp(services):
    """
    Return a webapp WSGI application with the PyAMF gateway at '/'
    """
    from google.appengine.ext import webapp
    from pyamf.remoting.gateway.google import WebAppGateway

    gateway = WebAppGateway(services)
    application_paths = [('/', gateway)]

    return webapp.WSGIApplication(application_paths)

Which with the new webapp2 code gives this error

Hi!

So did you manage to make webapp2 to work with WebAppGateway ?

Yours,
Andrew

[waterart]

I just tried to do a simple hello world and got the same problems.  I tried using the PyAMF version found here: https://github.com/njoyce/pyamf/tree/webapp2-gateway
and it did not work.

So I am rolling everything back to python 2.5x.  Hope that works and I can move on.

[Stuart Mitchell-3]

I had this problem as well I think I fixed it with the change in

https://github.com/stumitchell/pyamf

Though trunk has moved on since I forked my working version so I haven't tested that change against the newest trunk.

Using pyamf.remoting.gateway.wsgi.WSGIGateway is probably more reasonable in this case than supporting webapp/webapp2.

I wonder if google.WebAppGateway should be removed as it can cause some confusion.

Thoughts?
