Bug#748922: python-apt: TagFile doesnt close file

[Johannes Schauer <j.schauer@email.de>]

Package: python-apt
Version: 0.9.3.5
Severity: normal

Consider the following snippet:

--%<---------------------------------------------------
import gc
import os
import sys
import apt_pkg

print os.listdir("/proc/self/fd/")
f = apt_pkg.TagFile(sys.argv[1])
print os.listdir("/proc/self/fd/")
del f
print os.listdir("/proc/self/fd/")
gc.collect
print os.listdir("/proc/self/fd/")
-->%---------------------------------------------------

calling apt_pkg.TagFile() opens a file descriptor but that descriptor is
not closed when the object gets deleted or even garbage collection is
explicitly run. Here the output:

['0', '1', '2', '3']
['0', '1', '2', '3', '4']
['0', '1', '2', '3', '4']
['0', '1', '2', '3', '4']

The opened fd should be closed when the python object is destroyed.

cheers, josch
