Project description

# daemonize [![Build Status](https://secure.travis-ci.org/thesharp/daemonize.png)](http://travis-ci.org/thesharp/daemonize)

## Description daemonize is a library for writing system daemons in Python. It has some bits from [daemonize.sourceforge.net](http://daemonize.sourceforge.net). It is distributed under MIT license.

## Dependencies It is tested under following Python versions:

  • 2.6
  • 2.7
  • 3.3

## Installation You can install it from Python Package Index (PyPI):

$ pip install daemonize
## Usage

from time import sleep from daemonize import Daemonize

pid = “/tmp/test.pid”

def main():
while True:
sleep(5)

daemon = Daemonize(app=”test_app”, pid=pid, action=main) daemon.start()

## File descriptors Daemonize object’s constructor understands the optional argument keep_fds which contains a list of FDs which should not be closed. For example:

import logging from daemonize import Daemonize

pid = “/tmp/test.pid” logger = logging.getLogger(__name__) logger.setLevel(logging.DEBUG) logger.propagate = False fh = logging.FileHandler(“/tmp/test.log”, “w”) fh.setLevel(logging.DEBUG) logger.addHandler(fh) keep_fds = [fh.stream.fileno()]

def main():
logger.debug(“Test”)

daemon = Daemonize(app=”test_app”, pid=pid, action=main, keep_fds=keep_fds) daemon.start()
