# Module: dispatch_handler
# Author: Matt Giuca
# Date: 11/12/2007
# This is a mod_python handler program. The correct way to call it is to have
# Apache send all requests to be handled by the module 'dispatch'.
# This file is a wrapper around the dispatch module, necessary because
# mod_python does not (for some reason) load the handler directory into
# sys.path.
# It requires that the server config has the following line:
# PythonOption ivle.handlerpath "PATH-TO-IVLE"
# Sets sys.path with the correct path, then calls the handler in the dispatch
# module.
import sys
from mod_python import apache
def handler(req):
# A nasty hack :(
# The Apache httpd.conf needs to specify ivle.handlerpath as an option
# (see README).
try:
handlerpath = req.get_options()['ivle.handlerpath']
except KeyError:
# Note: "Internal Server Error" if "ivle.handlerpath" is not set
# (this is valid as it reflects an error in the Apache config
# But give useful feedback in debug mode
raise Exception("Missing configuration option 'ivle.handlerpath'")
if handlerpath not in sys.path:
sys.path.append(handlerpath)
import dispatch
import conf
return dispatch.handler(req)
