Class not loading properly in CGI

[Tom Chance]

Hullo,

I've got a very, very odd problem here which I can't seem to solve. I'm
creating a class instance in a CGI script, but that instance isn't
inheriting all of the methods associated with that file. Confused? Here's
what I mean:

the commands to check:
import db
mydb = db.mySQL()
print str(dir(mydb))

done in a python shell on my machine:
"['__doc__', '__init__', '__module__', 'connectTime', 'cursor', 'delete',
'fetchRow', 'fetchRows', 'info', 'insert', 'mysql', 'update']"

in the cgi script online:
['connectTime', 'cursor', 'mysql']

What on earth is going on?

Try printing db.__file__

That shows the correct .py file. Doing a dir() operation on the imported
class itself looks fine though:

db.mySQL (class) : ['__doc__', '__init__', '__module__', 'delete',
'fetchRow', 'fetchRows', 'info', 'insert', 'update']

mydb (class instance) : ['connectTime', 'cursor', 'mysql']

One further note of interest:

Python version: 1.5.2

Does this old version not handle classes in the same way? Or could it be
failing on some "new" syntax?

http://www.newtolinux.org.uk/techne/install.py shows the info gathered so
far.

Ah. This explains it. In 1.5.2, dir() did not return class attributes,
only instance attributes. The missing methods are still usable, you just
won't see them without examining mydb.__class__.
