fixuphandler with mod_wsgi

[Dominik Ruf]

Hi,

I currently use a mod_python fixuphandler to set an environment variable USER_EMAIL.

The value for this variable I get from a ldap request based on the user name that had been set by an apache auth module.

def fixuphandler(req):

    remote_user = req.user.split('\\')[-1]

    l = ldap.initialize("ldap://myserver:389")

    l.simple_bind_s("","")

    r = l.search_s("o=myorg", ldap.SCOPE_SUBTREE, "uid=%s" % remote_user)

    req.subprocess_env['USER_EMAIL'] = r[0][1]['mail'][0]

    return apache.OK

Since mod_python is dead (or dying) I am wondering if this is possible with mod_wsgi.

cheers

What is ultimately seeing the USER_EMAIL variable. A Python web
application, a PHP application, a CGI script or something else?

What you want to do is possible but only with help of a separate
package to mod_wsgi which doesn't make it necessarily practical at the
moment, especially since there has never been enough interest in the
separate package to make it worthwhile maintaining it.

The USER_EMAIL variable is used by a CGI application. (bugzilla to be exact)

What kin of additional package do I need.

I'm not sure if I understand this correctly, does such a package already exist?

I experimented with Apache Python bindings with SWIG. Results at:

https://bitbucket.org/grahamdumpleton/apswigpy/wiki/Home

There is a directive in mod_wsgi called:

WSGIPassApacheRequest On

which passes reference to AAA function in mod_wsgi:

http://code.google.com/p/modwsgi/wiki/AccessControlMechanisms

You can then do something like:

import apache.httpd
r = apache.httpd.request_rec(environ['apache.request_rec'])
r.subprocess_env['USER_EMAIL'] = 'asdasads'

The AAA functions though service a specific purpose and can't be
hooked for arbitrary purposes.

You might manage it with allow_access() function so long as that isn't
too early.

The apswigpy isn't really supported as there wasn't any interest in it.

OK thanks I'll give it a shot.
