Hi Christian, I already use the generator expression as Martin suggested
earlier today. Together with the decorator proposed by Jan. I had some
trouble with the test teardown method, but it seems I had a minor
problem in my environment as there was missing ~/.ipa/alias directory in
the test run.

I took the liberty to fix most of the pep8 issues while I was at it.
Thanks to Jan Cholasta for help with identifying this one.
IMO this would be more robust:
t = None
By assigning a value to the variable at the beginning you make sure
that the del statement will not fail.
Thanks for the idea. It also removed the version check.
Updated patch attached.
I have updated the fix for all of the leaks in that class. It seems to
corrupt the database even when no init/shutdown was called. Just not
NACK again. The problem is the reference counting. Even with this patch,
there seems to be at least one reference left after 't' is deleted and
nss.nss_shutdown races with the garbage collector.
Doesn't the PKCDDocument object also reference some NSS objects? It
might be worth trying to delete it manually before nss_shutdown as well.
Yes, this patch doesn't work. There are still some references left.
The problem may be on multiple places in here .
There may be a reference still bound to the doc label.
Another problem is that python 2 code:
[x for x in [123, 456]]
creates 2 references to 456 as the list used in the assert lives for
before it is garbage collected even though it is not reachable,
holding a reference to the object labeled as t.
In Python 2 the list comprehension leaks the internal loop variable. It
was an oversight in the design of list comprehensions. This has been
fixed in Python 3. You can work around the problem with a generator
expression inside list()
list(x for x in [123, 456])
is equivalent to
[x for x in [123, 456]]
except it doesn't leak x to the outer scope.
If you suspect an issue related to cyclic GC, you can force a garbage
collector run with gc.collect().
On the other hand, while not changing the job on jenkins I wonder why it
worked sometimes in this env.
