Aki Sukegawa commented on THRIFT-4089:
--------------------------------------

Sounds like version mismatch between compiler and library: 0.10.0 compiler 
against older python lib.

> Several issues with generated Python code: TFrozenDict, _fast_encode

>                 Key: THRIFT-4089
>                 URL: https://issues.apache.org/jira/browse/THRIFT-4089
>             Project: Thrift
>          Issue Type: Bug
>    Affects Versions: 0.10.0
>         Environment: Python 2.7. OS-X

> When you generate Python sources for a simple thrift file (e.g. Thrift 
> tutorial from https://thrift.apache.org/tutorial/py will also repro erros), 
> errors are thrown while running the PythonServer and PythonClient.
> 1.  When running the vanilla PythonServer, I get the following error:
> File "gen-py/shared/SharedService.py", line 9, in <module>
>     from thrift.Thrift import TType, TMessageType, TFrozenDict, TException, 
> TApplicationException 
> ImportError: cannot import name TFrozenDict
> I see this error consistently for all generated thrift files. The error 
> disappears on removing TFrozenDict from the generated files (it is not used 
> anywhere in the file).
> 2. When running the vanilla PythonClient (the server is now running after the 
> above fix), I get the following error:
>  File "PythonClient.py", line 51, in main
>     client.ping()
>   File "gen-py/tutorial/Calculator.py", line 73, in ping
>     self.send_ping()
>   File "gen-py/tutorial/Calculator.py", line 79, in send_ping
>     args.write(self._oprot)
>   File "gen-py/tutorial/Calculator.py", line 297, in write
>     if oprot._fast_encode is not None and self.thrift_spec is not None:
> AttributeError: TBinaryProtocol instance has no attribute '_fast_encode'
> I am not sure why this error is being thrown/what can be done to fix it.
> These two errors, and mainly the latter one, are rendering the Server/Client 
> un-usable. Is this a known issue? And how do you recommend working around it?
