# Module: dispatch_handler
22
# This is a mod_python handler program. The correct way to call it is to have
23
# Apache send all requests to be handled by the module 'dispatch'.
25
# This file is a wrapper around the dispatch module, necessary because
26
# mod_python does not (for some reason) load the handler directory into
28
# It requires that the server config has the following line:
29
# PythonOption ivle.handlerpath "PATH-TO-IVLE"
31
# Sets sys.path with the correct path, then calls the handler in the dispatch
35
from mod_python import apache
39
# The Apache httpd.conf needs to specify ivle.handlerpath as an option
43
handlerpath = req.get_options()['ivle.handlerpath']
44
if handlerpath not in sys.path:
45
sys.path.append(handlerpath)
48
conf.ivlepath = handlerpath
49
return dispatch.handler(req)
51
# Note: "Internal Server Error" if "ivle.handlerpath" is not set
52
# (this is valid as it reflects an error in the Apache config
53
# But give useful feedback in debug mode
