Something like this should work:
>>> import pickle, copyreg, ssl
>>>
>>> def save_sslcontext(obj):
... return obj.__class__, (obj.protocol,)
...
>>> copyreg.pickle(ssl.SSLContext, save_sslcontext)
>>>
>>> context = ssl.create_default_context()
>>> foo = pickle.dumps(context)
>>> _foo = pickle.loads(foo)
>>> _foo
<ssl.SSLContext object at 0x1011812a8>
>>> _foo.protocol
2
>>>
Basically, a SSLContext
needs a protocol
, and for whatever reason, the protocol
is not saved (e.g. it's not in a __reduce__
method) when the instance is pickled. If you need more state (i.e. other args
and kwds
from the __init__
method), then you'll need to extend the return value from the save_sslcontext
function above. (Note, if you are in python 2.x, then the appropriate module is copy_reg
).
