config.scan not found @xmlrpc_method

[sdayu]

I try to install pyramid 1.3.2 in new environment. When i ran old application I got xmlrpclib.Fault: <Fault -32601: 'server error; requested method not found'> My application use pyramid_rpc with @xmlrpc_method to config endpoint. I try to change @xmlrpc_method to config.add_xmlrpc_method, it work. I am not sure It is my mistake or pyramid 1.3.2 not support @xmlrpc_method

My first guess is that you aren't scanning the modules containing the @xmlrpc_method calls. Do you think you can submit a failing test case, or some example code that breaks?

[sdayu]

I am sure that pyramid application scan the modules containing the @xmlrpc_method because in this module I have other view use @view_config this function can run normally. On the way I try to run test case and show you.

This result when i ran unittest:

Hi guys, i have the same problem, config.scan don't work, i have to use config.add_xmlrpc_method(say_hello, endpoint='api', method='say_hello') in order for the server to handle xmlrpc request.

this is the code i have:

!/usr/bin/env python

from paste.httpserver import serve from pyramid.response import Response from pyramid.view import view_config

from pyramid_rpc.xmlrpc import xmlrpc_method

@xmlrpc_method(endpoint='api') def say_hello(request, name): return 'Hello, ' + name

if name == 'main': from pyramid.config import Configurator config = Configurator()

config.include('pyramid_rpc.xmlrpc')
config.add_xmlrpc_endpoint('api', '/api/xmlrpc')

#config.add_xmlrpc_method(say_hello, endpoint='api', method='say_hello')

config.scan()

app = config.make_wsgi_app()
serve(app, host='0.0.0.0')

Downgrading venusian to 1.0a4 or lower will fix this problem. I'm guessing that the problem relates to the scanning related change introduced in 1.0a4 ( which is NOT broken with pyramid-rpc ) and 'improved' in 1.0a5 which breaks pyramid-rpc.

[mmerickel]

I'm, so far, unable to reproduce this. I'm using the test app pasted by @nesiax and testing with the following:

import xmlrpclib
proxy = xmlrpclib.ServerProxy('http://localhost:8080/api/xmlrpc')
proxy.say_hello('bob')

Can someone give me any more details? I'm on OS X mountain lion and the combinations I have tested so far are python 2.6 and python 2.7, pyramid 1.3.4 and pyramid 1.4a2, venusian 1.0a5 and venusian 1.0a7.

To fix this environment I just need to...

then rerun the server and all is well

[mmerickel]

I copied your pip freeze into a requirements.txt and installed it. Still no errors. I do not have a spare freebsd system lying around. Have you tried creating a new virtualenv? I ask because for some reason you have pyramid_rpc 0.3 installed when 0.3.1 was released almost a year ago.

[cweimann]

I built a new virtualenv and changed the test app from @nesiax to use wsgiref because paste is no longer a requirement for pyramid and I want to install as little as possible. It still fails. I have tried this on FreeBSD 6.2, 8.3, and 9.0. Two of those with python 2.7.2 and one with python 2.7.3. I need to see if I can find a linux box.

I was able to reproduce the problem on an ubuntu machine and rolling back venusian does still fix it. Below is the freeze that fails.

[mmerickel]

I managed to reproduce this on an ubuntu 12.04 VM. Looking into it.

[mmerickel]

After a deep dive into venusian I've diagnosed the issue. It's been unknowingly fixed in pyramid_rpc master for a long time. Basically venusian 1.0a5 broke the feature where a decorator was using view_config. In pyramid_rpc's master, it no longer wraps view_config and, instead, calls venusian itself.

@cweimann can you please confirm that the master branch works for you and I will cut a new release fixing this.

[cweimann]

Excellent. This is working.

ok great, thanks for the help
