A gevent core implemented using libuv

uvent: A gevent core implemented using libuv

uvent is a gevent core implementation using the libuv library.

uvent uses pyuv, a Python interface for libuv. libuv is a high performance asynchronous networking library used as the platform layer for NodeJS.

libuv provides the same core functionality as libev, with some really nice additions:

  • High performance IO on Windows (not select)
  • Asyncronous file operations
  • Builtin thread pool
  • Asynchronous getaddrinfo
  • Nicer to use API
  • Etc.

Source code for uvent is on GitHub.

Motivation

This is an experimental project to test the feasibility of using libuv as a core for gevent.

Main functionality is working but not all tests are passing and there are some implementation caveats mostly due to the tight integration between gevent and libev. Implementation notes can be found in the NOTES.rst file.

Installation

uvent requires pyuv >= 0.10.0

pip install -U pyuv

Note: uvent only works with gevent >= 1.0rc1, earlier versions are not supported.

Using it

In order to use uvent add the following lines at the beginning of your project, before importing anything from Gevent:

import uvent
uvent.install()

Another way of doing this without modifying your code is by exporting environment variables before running your program:

export GEVENT_LOOP=uvent.loop.UVLoop
export GEVENT_RESOLVER=gevent.resolver_thread.Resolver
