Description

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._processMap[name](self, seqid, iprot, oprot)
File "py/gen-py/ThriftTest/ThriftTest.py", line 1202, in process_testException
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 gen-py/ThriftTest/ThriftTest.py doesn't catch TException.

def process_testException(self, seqid, iprot, oprot):
args = testException_args()
args.read(iprot)
iprot.readMessageEnd()
result = testException_result()
try:
self._handler.testException(args.arg)
except Xception, err1:
result.err1 = err1
oprot.writeMessageBegin("testException", TMessageType.REPLY, seqid)
result.write(oprot)
oprot.writeMessageEnd()
oprot.trans.flush()
