------------------------------------------

             Summary: Python server or cpp client do not handle the unimplemented method gracefully
                 Key: THRIFT-4150
                 URL: https://issues.apache.org/jira/browse/THRIFT-4150
             Project: Thrift
          Issue Type: Bug
          Components: C++ - Compiler, C++ - Library, Python - Compiler, Python - Library
    Affects Versions: 0.10.0
         Environment: Ubuntu Docker
            Reporter: James E. King, III
            Priority: Minor


I added a new method to the ThriftTest service and I implemented the server and client in C++.  In the C++ client I added exception handling to catch TProtocolException and std::exception.  I expected that when TestClient sent in a method that the server had not implemented, a TProtocolException(NOT_IMPLEMENTED) would be returned.  The server log indicates it got to this point in theory:
{noformat}
ERROR:root:'TestHandler' object has no attribute 'testRequired'
Traceback (most recent call last):
  File "/home/jking/thrift/github/thrift/test/py/gen-py/ThriftTest/ThriftTest.py", line 1593, in process_testRequired
    self._handler.testRequired(args.req)
{noformat}

However on the C++ client side, a std::exception was received and NOT a TProtocolException, which is a bug:

{noformat}
testClient.testRequired() =>*** FAILED *** got back std::exception Internal error
{noformat}
