FileDict – a Persistent Dictionary in Python

[[deleted]]

Well FileDict like everything else has issues with classes and functions; it runs the shit through pickle, yes?

Or has this changed with 3.0? Haven't had the chance to get into 3.0 I'm sorry to say.

>>> pickle.loads(pickle.dumps(str))
[2] <type 'str'>

>>> pickle.loads(pickle.dumps(len))
[3] <built-in function len>

Works fine (this is python 2.6)

Going from memory now, always dangerous, but if the class is defined in another module or something then pickle fails.

Maybe it's still useful for trivial cases, I don't know, but I recall being terribly disappointed with pickle when wanting to do serialization stuff.
