Thrift app and worker for gunicorn! Hence, a multi-process python thrift server!

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

• Python 2.7, all worker classes
• Python 3.4+, thriftpy_sync and thriftpy_gevent worker classes (code generated using the Thrift toolkit is not supported on Python 3)

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 -*-
   from pingpong_sdk.pingpong import PingService
   class PingpongServer(object):
    def ping(self):
    if os.environ.get('about_to_shutdown') == '1':
    raise PingService.AboutToShutDownException
    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

1. Write thrift app.

   #! /usr/bin/env python
   # tests/app.py
   # -*- coding: utf-8 -*-
   import thriftpy2
   from thriftpy2.thrift import TProcessor
   class PingPongDispatcher(object):
    def ping(self):
    return "pong"
   pingpong_thrift = thriftpy2.load("pingpong.thrift")
   app = TProcessor(pingpong_thrift.PingService, PingPongDispatcher())

2. Fire up app.

   % gunicorn_thrift tests.thriftpy_app:app -k thriftpy_sync \
    --thrift-protocol-factory \
    thriftpy2.protocol:TCyBinaryProtocolFactory \
    --thrift-transport-factory \
    thriftpy2.transport:TCyBufferedTransportFactory

Parameter: -k, --worker-class Config file: worker_class Default 2.7: thrift_sync Default 3.4+: thriftpy_sync

There are 4 types of workers available.

• thrift_sync: sync worker.
• thrift_gevent: gevent worker.
• thriftpy_sync: sync worker, adapted for thriftpy2
• thriftpy_gevent: gevent worker, adapted for thriftpy2

note: If you want to use thriftpy_sync or thriftpy_gevent, make sure the following:

• Version of thriftpy2 should be higher than 0.1.10.
• --thrift-protocol-factory should be set to either:
  1. thriftpy2.protocol:TCyBinaryProtocolFactory or
  2. thriftpy2.protocol:TBinaryProtocolFactory
• --thrift-transport-factory should be set to either:
  1. thriftpy2.transport:TCyBufferedTransportFactory or
  2. thriftpy2.transport:TBufferedTransportFactory

The transport factory to use for handling connections.

Parameter: --thrift-transport-factory
Config file: thrift_transport_factory
Default 2.7: thrift.transport.TTransport:TBufferedTransportFactory
Default 3.4+: thriftpy2.transport:TBufferedTransportFactory

The protocol factory to use for parsing requests.

Parameter: --thrift-protocol-factory
Config file: thrift_protocol_factory
Default 2.7: thrift.protocol.TBinaryProtocol:TBinaryProtocolAcceleratedFactory
Default 3.4+: thriftpy2.protocol:TBinaryProtocolFactory

Seconds to timeout a client if it is silent after this duration.

Parameter: --thrift-client-timeout
Config file: thrift_client_timeout
Default: None (Never time out a client)

This config will run a seperate thread to detect gevent ioloop block every specified seconds.

Parameter: --gevent-check-interval
Config file: gevent_check_interval
Default: 0

Note: DONOT USE this if not running gevent worker.
