I tried it again with a much bigger archive to make sure it takes a long
while, and still no trouble. What you are saying implies that the unzip
process is somehow async. But your code should be blocking on the entire
thing. Are you doing this to a network location? If so, you could be
dealing with a network cache or latency. I see this is a windows exception,
so I might not be running into the same issues as you on osx, with how
windows is running the unzips.
What you might need to do then is wrap the last line of your context
manager in a try..except that maybe tries 10 times with some sleeps, before
failing:
@contextlib.contextmanager
def make_temp_directory():
temp_dir = tempfile.mkdtemp()
yield temp_dir
i = 0
while i < 10:
try:
shutil.rmtree(temp_dir)
except:
time.sleep(.1)
else:
return
raise IOError("Failed to remove temp path: %s" % temp_dir)
