--------------------------------------
Affects Version/s: 0.12.0
> PYTHON: deserialize does not work with python.immutable

> Key: THRIFT-4810

> Project: Thrift
> Issue Type: Bug
> Affects Versions: 0.12.0
> Reporter: Mathias Nisted Velling
> Priority: Major
>
> Hi,
> In the python thrift implementation, the thrift.TSerialization.deserialize
> does not work with structs that are marked as python.immutable.
> This is because deserialize(base, buf, protocol) assumes base is modified by
> base.read(..), but due to the immutability, base.read(..) instead returns a a
> new instance of type(base), so when deserialize returns base, it is still
> just an empty object:
> {code:java}
> def deserialize(base,
> buf,
> protocol_factory=TBinaryProtocol.TBinaryProtocolFactory()):
> transport = TTransport.TMemoryBuffer(buf)
> protocol = protocol_factory.getProtocol(transport)
> base.read(protocol)
> return base{code}
>
> It should probably instead just return the output of base.read(..):
> {code:java}
> def deserialize(base,
> buf,
> protocol_factory=TBinaryProtocol.TBinaryProtocolFactory()):
> transport = TTransport.TMemoryBuffer(buf)
> protocol = protocol_factory.getProtocol(transport)
> return base.read(protocol){code}
