Tomaz Muraus commented on LIBCLOUD-705:
---------------------------------------
I had a look into it today and the problem is that Node (and other classes such
as DNSRecord, etc.) contain a reference to the Driver which contains a
reference to the Connection which contains many unpicklable variables.
I will look into defining a custom __getstate__ for the driver class which
doesn't try to pickle the Connection instance, but only the kwargs which are
required to build the instance and then re-create the connection instance when
unpickling the object in __setstate__.
> Pickling of Nodes isn't supported - TypeError: a class that defines __slots__
> without defining __getstate__ cannot be pickled
