-------------------------------------
Summary: 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
Reporter: Manasi Vartak
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?
