pyuv 1.2.0

Python interface for libuv

pyuv is a Python module which provides an interface to libuv. libuv is a high performance asynchronous networking and platform abstraction library.

libuv is built on top of epoll/kequeue/event ports/etc on Unix and IOCP on Windows systems providing a consistent API on top of them.

pyuv’s features:

  • Non-blocking TCP sockets
  • Non-blocking named pipes
  • UDP support (including multicast)
  • Timers
  • Child process spawning
  • Asynchronous DNS resolution (getaddrinfo)
  • Asynchronous file system APIs
  • High resolution time
  • System memory information
  • System CPUs information
  • Network interfaces information
  • Thread pool scheduling
  • ANSI escape code controlled TTY
  • File system events (inotify style and stat based)
  • IPC and TCP socket sharing between processes
  • Arbitrary file descriptor polling
  • Thread synchronization primitives

CI status

Stable branch (v1.x)

  • Travis CI:
  • AppVeyor:


Starting with version 1.0.0, pyuv follows the Semantic Versioning spacification, like libuv does.

All releases are downloadable from the GitHub tags page, and the latest stable release from PyPI.


pyuv can be installed via pip as follows:

pip install pyuv


Get the source:

git clone



Mac OSX:

(XCode needs to be installed)
export ARCHFLAGS="-arch x86_64"

Microsoft Windows (with Visual Studio):

python build_ext --inplace

Running the test suite

There are several ways of running the test ruite:

  • Run the test with the current Python interpreter:

    From the toplevel directory, run: nosetests -v

  • Use Tox to run the test suite in several virtualenvs with several interpreters

    From the toplevel directory, run: tox this will run the test suite on Python 2.7, 3.3 and 3.4 (you’ll need to have them installed beforehand)
