Pickle protocol 1, currently in use in Python 2, doesn't call __getnewargs__
, for that we'd need protocol 2+ (see #179 ):
>>> class X(object):
... def __getnewargs__(self):
... raise Exception("getnewargs")
...
>>> import cPickle
>>> cPickle.dumps(X(), 1)
'ccopy_reg\n_reconstructor\nq\x01(c__main__\nX\nq\x02c__builtin__\nobject\nq\x03NtRq\x04.'
>>> cPickle.dumps(X(), 2)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 3, in __getnewargs__
Exception: getnewargs

Are these the same as persistent classes?
Perhaps take a look at src/ZODB/persistentclass.*
What version of Python are you using?
from zodb.
There've been no comments from the OP since 2014, and the pickle protocol has been updated which theoretically solves this, so I'm going to go ahead and close it.
