Package: python-debian
Version: 0.1.29
Severity: normal
We wrote a python system to manipulate Debian CDs and resolve dependencies
based on local caches.
We started out having our ouwn "debianPackage" class, but about 4 months ago, I
came across the python-debian code.
After reading the documentation, we downgraded our debianPackage class to be a
wrapper around the python-debian classes.
After applying this, we started getting reports of a significant slowdown; we
planned to look at it "later".
This week, when working on a new system, we started getting failures with 'too
many filehandles'.
When inspecting deeper, ArFile kept a filehandle open for every package that is
added to the (local) debian Pool that is being processed (I assume it gets the
data on request instead of caching it in the objects).
As a result, we re-implemented the relevant parts to avoid this file handle
leak (?).

Hi Marc,
I've tried several times to make a loop that iterates over .deb files, opens
them, extracts information, etc, but I can't find a way to reproduce the
problem.
If you (or someone else) can provide a way of reproducing it then I'm very
happy to look at this again -- reopening this bug or filing a new one is fine.
regards
Stuart
