I subclassed the dict class and added a __setstate__ method because I
want to add some extra steps when I unpickle these entities. This is a
toy example of what I am doing:
class Entity(dict):
def __setstate__(self, d):
log.debug("blah...")
Based on my experiments, the data in d *IS NOT* the data stored in my
instances when I do stuff like:
e = Entity()
e['a'] = 1
Instead, the stuff in d is the data stored when I do stuff like:
e.fibityfoo = 99
Yes. The dict contents are pickled directly; __getstate__ and __setstate__
are related to the instance attributes (fibityfoo), not its contents
(a->1).
Try defining __reduce__ or __reduce_ex__ instead.
Is there anything I have to do to make sure that my real dictionary data
is correctly reloaded during the unpickle phase? In other words, should
I run super(Entity, self).__setstate__(d) or something like that?
That doesn't work, dict.__setstate__ doesn't even exist.
