What steps will reproduce the problem?
1. Read in a pcap file with IPv4 frames
2. Create ethernet object dpkt.ethernet.Ethernet(eth)
3. Try to pickle it "pickle.dump(eth_cls,file)"
What is the expected output? What do you see instead?
I expect that the data be pickled. Output is this
TypeError: a class that defines __slots__ without defining __getstate__ cannot
be pickled
What version of the product are you using? On what operating system?
dpkt version 1.7 on windows Vista with Python 2.6
Please provide any additional information below.
I tried removing the __slots__ attribute from the _MetaPacket class in the dpkt
module and adding the dynamically attributes to the dictionary directly which
did allow me to pickle the class. However this then cause the actual data frame
to be stored twice in the __dict__ which increases the size. I am sure they is
a better way to accomplish this but I am unfamailar with how meta classes work
and didn't want to break anything.
