gevent compatibility layer for pyzmq

Project description

Wrapper of pyzmq to make it compatible with gevent. ØMQ socket operations that would normally block the current thread will only block the current greenlet.

Inspired by Ben Ford’s work on ØMQ support in eventlet.

Requirements

Requires pyzmq>=2.1.0

Before version 2.1.0 (of both ØMQ and pyzmq) the underlying file descriptors that this library utilizes were not available.

Usage

Instead of importing zmq directly, do so in the following manner:

from gevent_zeromq import zmq

Any calls that would have blocked the current thread will now only block the current green thread.

About

This compatibility is accomplished by ensuring the nonblocking flag is set before any blocking operation and the ØMQ file descriptor is polled internally to trigger needed events.

Will build with cython if available. In my simple nonscientific test this resulted in an almost 50% speedup in a local 1-1 PUB SUB sending of 100,000 1K messages in a single tight loop.

There are plans to further the integration with both gevent and pyzmq via cython for speed.
