ConcurrentLogHandler

You can install this module by issuing the following command:

python setup.py install

To build a Python "egg", use the following:

python seutp.py bdist_egg
# Copy the .egg file from under the "dist" folder

Here is a simple usage example:

from logging import getLogger, INFO
from cloghandler import ConcurrentRotatingFileHandler
import os

log = getLogger()
# Use an absolute path to prevent file rotation trouble.
logfile = os.path.abspath("mylogfile.log")
# Rotate log after reaching 512K, keep 5 old copies.
rotateHandler = ConcurrentRotatingFileHandler(logfile, "a", 512*1024, 5)
log.addHandler(rotateHandler)
log.setLevel(INFO)

log.info("Here is a very exciting log message, just for you")

To use this module from a logging config file, use a handler entry like this:

[handler_hand01]
class=handlers.ConcurrentRotatingFileHandler
level=NOTSET
formatter=form01
args=("rotating.log", "a", 512*1024, 5)

Note: you must have a "import cloghandler" before you call fileConfig(). For more information see http://docs.python.org/lib/logging-config-fileformat.html

NOTES: This module has not yet be tested in a multi-threaded environment. I see no reason why this should be an issue, but no stress-testing has been done in a threaded situation. If this is important to you, you could always add threading support to the stresstest.py script and send me the patch.
