Let's you (optionally) specify either a result value or an exception type
and a callback which is returned, thrown or called respectively if a
PolicyKit authorization doesn't exist or can't be obtained in the DBus
mechanism, i.e. an appropriate DBus exception is thrown.
An exception constructor may and a callback must accept an `action_id´
parameter which will be set to the id of the PolicyKit action for which
authorization could not be obtained.
Examples:
1) Return `False´ in the event of an authorization problem, and call
`error_handler´:
def error_handler(action_id=None):
print "Authorization problem:", action_id
class MyProxy(object):
@polkit.enable_proxy(authfail_result=False,
authfail_callback=error_handler)
def some_method(self, ...):
...
2) Throw a `MyAuthError´ instance in the event of an authorization problem:
class MyAuthError(Exception):
def __init__(self, *args, **kwargs):
action_id = kwargs.pop("action_id")
super(MyAuthError, self).__init__(*args, **kwargs)
self.action_id = action_id
class MyProxy(object):
@polkit.enable_proxy(authfail_exception=MyAuthError)
