[Twisted-web] getChild in python3

[Nathaniel Haggard]

# This code doesn't call getChild in python3, but it does in python2
(python2 throws AttributeError, but python3 doesn't) with "curl
http://127.0.0.1:8803/bug/a" and Twisted==19.7.0 with python3.5.2:

from twisted.application import internet, service, strports
from twisted.web.resource import Resource
from twisted.web.server import Site
from twisted.internet import reactor
from twisted.python import log


from twisted.web.resource import Resource



class R(Resource):
    allowedMethods=('GET',)
    def getChild(self, name, request):
        pass


r = Resource()
r.putChild('bug', R())

application = service.Application('web')
site = Site(r)
sc = service.IServiceCollection(application)
i = strports.service("tcp:8803", site)
i.setServiceParent(sc)
