creating python daemon ?

[vineet daniel]

Hi

I have succesfully created daemon with python script and as next step
I am trying to give input to that python script daemon from Apache
Logs....here I have got stuck and I have even checked IRC python
channel for solution. Apache is able to call the file but fails to
execute it properly and I get this error continuosly :

piped log program '/var/www/html/test.py' failed unexpectedly

How do I rectify the above error and make adjustment to the code so
that it takes input from apache.

code that I am using is as follows :

#! /usr/bin/env python
import sys,os
pid = os.fork()
os.chdir("/var/www/html/")
os.setsid()
os.umask(0)
#this line will read apache log in real time as redirected from the
CustomLog directive of Apache.
log = sys.stdin.readlines()
f = open('/var/www/logmongo.txt','a') # append log to this text file
f.write(log)

I'd appreciate if anybody could share the code that they used for
daemon or used with Apache CustomLog directive.
