Roger Meier commented on THRIFT-2659:
-------------------------------------
please analyse TException Handling in C++, it works there.
> python Test Server fails when throwing TException
> -------------------------------------------------

> Key: THRIFT-2659
> URL: https://issues.apache.org/jira/browse/THRIFT-2659
> Project: Thrift
> Issue Type: Sub-task
> Components: Python - Compiler, Python - Library, Test Suite
> Reporter: Chamila Dilshan Wijayarathna

> As ThriftTest.thrift has defined TestException has 3 scenarios.
> if arg == "Xception" throw Xception with errorCode = 1001 and message = arg
> else if arg == "TException" throw TException
> else do not throw anything
> But when testException("TException") is called, python server is failing
> saying
> testException(TException)
> ERROR:root:This is a TException
> Traceback (most recent call last):
> File "py/../../lib/py/build/lib.linux-x86_64-2.7/thrift/server/TServer.py",
> line 86, in serve
> self.processor.process(iprot, oprot)
> File "py/gen-py/ThriftTest/ThriftTest.py", line 1006, in process

> self._handler.testException(args.arg)
> File "py/TestServer.py", line 115, in testException
> raise TException(message='This is a TException')
> TException: This is a TException
> It looks like this causes since auto generated
