daemon.DaemonContext and logging

S

Sean DiZazzo

I'm finally getting around to trying out the python-daemon module and
have hit a wall. I'm trying to set up logging inside of the "with
daemon.DaemonContext" block. But when I try to use a logger inside
the block it throws an error:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
from __future__ import with_statement

import logging
import logging.handlers
import daemon
import daemon.pidlockfile
import sys

logger = logging.getLogger("DaemonLog")
logger.setLevel(logging.INFO)
formatter = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s
- %(message)s")
handler = logging.FileHandler("log.file")
logger.addHandler(handler)

pid = daemon.pidlockfile.TimeoutPIDLockFile("/var/run/daemontest.pid",
10)

with daemon.DaemonContext(pidfile=pid, gid=0, uid=0,
stdout=sys.stdout, stderr=sys.stderr):
logger.info("POO")
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I get the following traceback:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Any advice? Also, I left in the call to TimeoutPIDLockfile() as well,
because the library's documentation is pretty sparse, and I want to
know if I'm using it properly.

Thanks in advance.
