Thrift app and worker for gunicorn!

• graceful reload/shutdown.
• manage worker number at runtime.
• and everything else gunicorn has to offer.

1. Generate thrift files:

   % thrift --out tests/pingpong_sdk --gen py:new_style,utf8strings tests/pingpong.thrift

2. Write thrift app.

   #! /usr/bin/env python
   # tests/app.py
   # -*- coding: utf-8 -*-
   
   import os
   from pingpong_sdk.pingpong import PingService
   
   class PingpongServer(object):
       def ping(self):
           return "pong"
   
   app = PingService.Processor(PingpongServer())

3. Fire up app.

   % gunicorn_thrift tests.app:app -k thrift_sync
   % gunicorn_thrift tests.app:app -k thrift_gevent

Parameter: -k, --worker-class

• Version of thriftpy should be higher than 0.1.10.
• --thrift-protocol-factory should be set to either thriftpy.protocol:TCyBinaryProtocolFactory or thriftpy.protocol:TBinaryProtocolFactory
• --thrift-transport-factory should be set to either thriftpy.transport:TCyBufferedTransportFactory or thriftpy.transport:TBufferedTransportFactory

The transport factory to use for handling connections.

Parameter: --thrift-transport-factory
