Comment (by David Sanders):
Thanks Tim, that script helps me quickly reproduce on my setup.
I've further narrowed it and confirmed what Chris said about parallelism
being a factor. If you use `--parallel 1` to disable parallelism it won't
reproduce.
I've narrowed it down to the parallel interaction between two test cases.
It makes sense, the latter is also dealing with `window.png` and changes
the modification timestamp on it which changes the hash.
{{{
for i in {1..500};
do
python tests/runtests.py
staticfiles_tests.test_storage.TestCollectionCachedStorage
staticfiles_tests.test_storage.TestCollectionHashedFilesCache
retcode=$?
if [ $retcode = 1 ]; then
echo $i;
echo 'failed';
break;
fi
done
}}}
That's all the digging I've got time for tonight. I'll start to look into
a fix tomorrow, unless someone wants to pounce on it before me now that
it's narrowed down.
