Good evening everyone!This post is English translation of here.
node.js which is server-side-Java Script is recently popular.
The library libuv for networks which the author of node.js is making is API of the libev style currently used on the back side of gevent.
The talk that Windows could also be used was heard, and since it seems to be pleasant, it used.
There was no document, and since I am poor at C, I looked for Python wrapper.
I found ↓.
It is not installable from the Pypi.
$ git clone https://github.com/saghul/pyuv.git $ python setup.py build $ sudo python setup.py install
Execute TCP Echo Server.
import os import signal import threading import pyuv def on_client_shutdown(client): client.close() clients.remove(client) def on_read(client, data): if data is None: client.close() clients.remove(client) return data = data.strip() if not data: return client.write(data+os.linesep) client.shutdown(on_client_shutdown) def on_connection(server): client = server.accept() clients.append(client) client.start_read(on_read) def async_exit(async): [c.close() for c in clients] async.close() signal_h.close() server.close() def signal_cb(sig, frame): async.send(async_exit) print "PyUV version %s" % pyuv.__version__ loop = pyuv.Loop() async = pyuv.Async(loop) clients =  server = pyuv.TCP(loop) server.bind(("0.0.0.0", 5000)) server.listen(on_connection) signal_h = pyuv.Signal(loop) signal_h.start() t = threading.Thread(target=loop.run) t.start() signal.signal(signal.SIGINT, signal_cb) signal.pause() t.join() print "Stopped!"
Echo Server Benchmark
The benchmark was taken for methane/echoserver · GitHub to reference.
※ The execution result in VM
※ A server and a client are operated by the same VM. This is not good.
※ 4core 1024M Environment
Speed is somewhat slow compared with Tornado. The design of pyuv resembles Tornado.
No Document？Reading Header File
libuv can be easily used by using pyuv.
It is very fun.
