Thrift app and worker for gunicorn!
Python Thrift


Build Status

Thrift app and worker for gunicorn!


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

Supported Platforms

  • Python 2.7, all worker classes
  • Python 3.2+, thriftpy_sync worker class (neither gevent nor code generated using the Thrift toolkit are supported on Python 3)


Using thrift

  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/
    # -*- 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 -k thrift_sync
    % gunicorn_thrift -k thrift_gevent

Using thriftpy

  1. Write thrift app.

    #! /usr/bin/env python
    # tests/
    # -*- coding: utf-8 -*-
    import thriftpy
    from thriftpy.thrift import TProcessor
    class PingPongDispatcher(object):
        def ping(self):
            return "pong"
    pingpong_thrift = thriftpy.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 \
        thriftpy.protocol:TCyBinaryProtocolFactory \
      --thrift-transport-factory \



Parameter: -k, --worker-class Config file: worker_class Default 2.7: thrift_sync Default 3.2+: thriftpy_sync

There are 4 types of workers available.

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

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

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

Transport factory

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 3.2+: thriftpy.transport:TBufferedTransportFactory

Protocol factory

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 3.2+: thriftpy.protocol:TBinaryProtocolFactory

Client timeout

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)
