I understand that the way the authorizer machinery is assembled into twisted seems to be morphing (and not completely propagated into other twisted components yet, hence all the deprecation messages when running the unit tests), and I was trying to see if I could do things properly (the new way) in my code -- but not successfully yet, I guess, because when running this (shamelessly purloined and modified from the pgquoter.py example): from twisted.spread import pb from pdmengine import BasePdmEngine class PdmClient(pb.Perspective): def perspective_getProductsByProject(self): return self.service.BasePdmEngine.getProductsByProject(project) class PdmPBService(pb.Service): def __init__(self, engine, serviceName, authorizer, application=None): pb.Service.__init__(self, serviceName, authorizer, application) perspectiveClass = PdmClient --- ... with mktap I still get: /home/waterbug/sandbox/TwistedPlugins/TwistedPdm/pdmpb.py:10: DeprecationWarning: You have to pass an authorizer separately from an application now. pb.Service.__init__(self, serviceName, authorizer, application) /usr/local/lib/python2.2/site-packages/twisted/cred/service.py:72: DeprecationWarning: Application.authorizer attribute is deprecated, use Service.authorizer instead authorizer = sp.authorizer /usr/local/lib/python2.2/site-packages/twisted/spread/pb.py:972: DeprecationWarning: Application.authorizer attribute is deprecated, use Service.authorizer instead auth = auth.authorizer Saving pgpdm application to pgpdm.tap... Saved. --- I understand the second 2 warnings, which are internal to twisted, but I'm puzzled by the first one, which refers to this line: pb.Service.__init__(self, serviceName, authorizer, application) ^^^^^^^^^^ I thought I _was_ passing an authorizer separately! Suggestions? What should the syntax be under the new authorizer regime? tnx! -- Steve. Stephen C. Waterbury http://misspiggy.gsfc.nasa.gov/people/waterbug.html
