webapp2_extras protorpc does not work on Python 2.7 about webapp-improved HOT 11 CLOSED

I'm guessing this happens because:

- protorpc.service_handlers.ServiceHandler extends webapp.RequestHandler (which 
is webapp2.RequestHandler in the new runtime).
- webapp2_extras.protorpc.ServiceHandler extends webapp2.RequestHandler and 
protorpc.service_handlers.ServiceHandler.

I can provide a workaround for the new runtime.

Did you try to use protorpc directly? 

Also: can I have a copy of the google.appengine.ext.webapp code used in the 2.7 
runtime? These things pass my tests but I'm of course using the current SDK 
webapp.

Sorry for taking so long to answer to this.

I've been thinking on the subject and the best would be probably to remove 
webapp2_extras.protorpc. It is only usable with the 2.5 runtime, and has no 
reason to exist when webapp2 replaces webapp: it is protorpc that needs to 
support webapp2 in the 2.7 runtime, as it it did with webapp.

I am trying to migrate from python2.5 to python2.7 in Google App Engine (SDK 
1.6). And got an error when trying GET ProtoRPC service on dev environment:

  File ".../google_appengine/google/appengine/runtime/wsgi.py", line 174, in Handle
    result = handler(self._environ, self._StartResponse)
  File ".../google_appengine/lib/webapp2/webapp2.py", line 1519, in __call__
    response = self._internal_error(e)
  File ".../google_appengine/lib/webapp2/webapp2.py", line 1511, in __call__
    rv = self.handle_exception(request, response, e)
  File ".../google_appengine/lib/webapp2/webapp2.py", line 1505, in __call__
    rv = self.router.dispatch(request, response)
  File ".../google_appengine/lib/webapp2/webapp2.py", line 1253, in default_dispatcher
    return route.handler_adapter(request, response)
  File ".../google_appengine/lib/webapp2/webapp2.py", line 1040, in __call__
    return self.handler(request, *args, **kwargs)
TypeError: __call__() takes exactly 1 argument (4 given)

If I change: "from protorpc.webapp import service_handlers" to "from 
webapp2_extras.protorpc import service_handlers"
then error the same as described above.

Application created with code as below:
application = 
webapp2.WSGIApplication(service_handlers.service_mapping([('/service', 
SomeService),]))

Could you provide some workaround how to use ProtoRPC with python2.7 in Google 
App Engine?

I believe the ProtoRPC project should provide a way.

The webapp2_extras.protorpc package will be removed as it makes no sense to 
maintain it anymore.

I have the same issue as Comment #4. Per Comment $5, I have created an issue 
for this under protorpc (Issue #38) : 
http://code.google.com/p/google-protorpc/issues/detail?id=38

webapp2_extras.protorpc was removed from version 2.4. 

I'd like to support this but there's a bit too much magic involved, so better 
to have it as a separated, actively maintained project (or if protorpc project 
supports it by default).

In the meantime, does anybody have a workaround for this?

I'd like to mention that ProtoRPC is moving away from the webapp handler (in 
part because of the problem discussed here) and to a simpler WSGI based model.  
There is inadequate documentation at this time, however, I've updated the 
original ProtoRPC project page with an example that uses the new WSGI library.  
You can see it here:

  http://code.google.com/p/google-protorpc/

There is also support for multiple service handlers, however, the forms 
interface has not yet been ported.

I copied and pasted your example on http://code.google.com/p/google-protorpc/ 
and it doesn't work. The new app.yaml files with .app require you to have an 
attribute called app. So I modified my file to use app = 
webapp.WSGIApplication(service_mappings), but then I get the same error as #4. 
Does protorpc on app engine actually work with 2.7 runtime at this point?
