Pre-marshal / Proxy removal

>>> sample = {'foo': (1, ['x', 'y', 1.2])}

if we put the sample in a security proxy:

>>> from zope.security.checker import ProxyFactory
>>> proxied_sample = ProxyFactory(sample)

We can still get to the data, but the non-rock data is proxied:

>>> from zope.security.proxy import Proxy
>>> proxied_sample['foo']
(1, ['x', 'y', 1.2])

>>> type(proxied_sample['foo']) is Proxy
True
>>> type(proxied_sample['foo'][1]) is Proxy
True

But we can strip the proxies using premarshal:

>>> from zope.publisher.xmlrpc import premarshal

>>> stripped = premarshal(proxied_sample)
>>> stripped
{'foo': [1, ['x', 'y', 1.2]]}

>>> type(stripped['foo']) is Proxy
False
>>> type(stripped['foo'][1]) is Proxy
False

So xmlrpclib will be happy. :)

We can also use premarshal to strip proxies off of Fault objects. We have to make a security declaration first though:

>>> import xmlrpclib
>>> fault = xmlrpclib.Fault(1, 'waaa')
>>> proxied_fault = ProxyFactory(fault)
>>> stripped_fault = premarshal(proxied_fault)
>>> type(stripped_fault) is Proxy
False

Standard python datetime objects are also handled:

>>> import datetime
>>> sample = datetime.datetime(2006,06,17,21,41,00)
>>> stripped_date = premarshal(sample)
>>> isinstance(stripped_date, datetime.datetime)
False
>>> isinstance(stripped_date, xmlrpclib.DateTime)
True

We can also use premarshal to strip proxies off of Binary objects. We have to make a security declaration first though:

>>> import xmlrpclib
>>> binary = xmlrpclib.Binary('foobar')
>>> proxied_binary = ProxyFactory(binary)
>>> stripped_binary = premarshal(proxied_binary)
>>> type(stripped_binary) is Proxy
False
