apache2 + libapache2-mod-python + libgv-python + graphviz hangs

[Lari Huttunen]

Take a fresh Ubuntu {7.10,8.04} install

$ sudo apt-get update
$ sudo apt-get install graphviz libgv-python
$ sudo apt-get install apache2 libapache2-mod-python
$ sudo a2enmod mod_python

$ sudo vi /etc/apache2/sites-enabled/000-default

Replace the existing Directory /var/www entry with the following

     <Directory /var/www/>
          Options Indexes FollowSymLinks MultiViews
          AllowOverride None
          Order allow,deny
          allow from all

          AddHandler mod_python .py
          PythonHandler test
          PythonDebug On
    </Directory>

$ sudo cat > /var/www/test.py
import gv
from mod_python import apache

def handler(req):
    req.content_type = 'text/plain'
    gv.graph('a')
    req.write("Test OK!")
    return apache.OK
^D

$ sudo apache2ctl restart

Navigate to http://localhost/test.py. Observe that the text "Test OK!"
never shows, that the script never returns, and that the apache2
process stalls.

Tested this issue on current Debian Unstable (lenny/sid) and could not reproduce this problem.
The issue seems to be stemming from the fact that Ubuntu uses Python 2.5.2 and
Debian uses Python 2.4.5.

Btw, what is the rationale in choosing a different version of Python from Debian as the base?

[Lari Huttunen (debian-huttu)]

The bug seems to be in libapache2-mod-python.

[Thomas Hotz (thotz-deactivatedaccount)]

Is this bug still an issue for you? Which Ubuntu version do you use now?
