Python 2.3 deployment

Hey guys!

I have no choice but deploy to this server, running CentOS
4.4, with no
option to upgrade python beyond 2.3, and I'm getting this:

Mod_python error: "PythonHandler
django.core.handlers.modpython"

Traceback (most recent call last):

Something's a bit broken with your setup, then. Certainly
random.randint() existedin Python 2.3 (I just tested it).

Do a quick test to confirm that it really is missing in a
shell:

        Python 2.3.5 (#1, Mar 11 2007, 08:55:14) 
        [GCC 4.1.1 20070105 (Red Hat 4.1.1-51)] on linux2
        Type "help", "copyright",
"credits" or "license" for more
        information.
        >>> import random
        >>> random.randint
        <bound method Random.randint of <random.Random
object at
        0x672110>>

If that fails, your python installation is very
non-standard. You could
also try looking at the results of "rpm -qV
python" to check that there
hasn't been any inadvertent (or deliberate) changes to the
installed
rpm.

Note sure what to suggest here. The problem looks to be in
your
installation. Start asking serious questions of the sys
admin.

Malcolm

Thanks, Malcolm!

For some reason, updating django to trunk solved it. My
system admins
told me kindly that it's not their problem. Very nice
indeed.

Huh I lied. The django update only forced me to call that
view with
POST, and now that I'm doing, it's throwing the same
traceback. I'm not
sure what this might be. I'll check again with the system
admins.

When you tested at the interactive prompt -- which doesn't
involve
Django at all, did your random module contain a randint
function? That
would be the first thing to establish.

Malcolm

You can test what random module you are using:

insert a line above: assert False, random.__file__

You can test the random module:

python /usr/lib64/python2.4/random.py
2000 times random
0.003 sec, avg 0.497669, stddev 0.288045, min 0.00160483,
max 0.99949
2000 times normalvariate
....

HTH,
 Thomas

Hi guys!

Thanks for those responses. So, the random.randint function
does exist:
# python
Python 2.3.5 (#1, Aug 25 2005, 09:17:44) 
[GCC 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)] on linux2
Type "help", "copyright",
"credits" or "license" for more
information.
>>> import random
>>> random.randint
<bound method Random.randint of <random.Random object
at 0x80a6c6c>>

And here's whar Thomas suggests:
AssertionError at /
/usr/lib/python2.3/random.pyc
