Posix Concurrent File Handler

Provides concurrent rotating file handler for posix-compatible OSes.

By default multiprocessing.Lock is used. If you fork from one process that configures logger this case is preferred because of speed. If you have many undependantly started processes you should use instance of ploghandler.Lockf class. The Lockf class uses fcntl.lockf call described in man 3 lockf. Optinally ploghandler.Flock (man 2 flock) can be used.

Supported versions:

Currently supported versions: 2.6, 2.7 and 3.4.

Example:

import logging

from ploghandler import PLogHandler, Lockf

log = logging.getLogger("test")
handler = PLogHandler(
    "/var/log/test.debug.log",
    maxBytes=1024 * 1024,
    backupCount=5,
    rotlock=Lockf("/var/log/test.debug.lock"))

log.addHandler(handler)
log.setLevel(logging.DEBUG)

log.debug("test message")
