Installation

Usage

-----

.. code-block:: python

    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:

.. code-block:: python

    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()
