Description

When using GeoIP in my code I am getting such error at the end of syncdb call:

Exception TypeError: "'NoneType' object is not callable" in <bound method GeoIP.__del__ of <django.contrib.gis.utils.geoip.GeoIP object at 0x103a35690>> ignored

It seems there is some race condition? I am using Python 2.7.2 on Mac OS X. It has threaded support enabled. Django 1.3. python-geoip 1.2.5, libgeoip 1.4.7.

It could be useful if anyone could provide us with a basic project where this error can be reproduced.

I can confirm this on Django 1.4.3 with geoip 1.4.8.

I attached a test project that should reproduce this error. Instructions: Extract, install requirements (Django==1.4.3) and run runtest.sh which downloads GeoIP country data (slightly too big to attach) and then does a syncdb (any Django command will do).

The exception should be the last line of the output. The culprit is obviously in django.contrib.gis.geoip.base.GeoIP.__del__ where GeoIP_delete is None when this method is called.

Replacing __del__ with the following removes the exception, but may leave file handles lying around (I have no deeper knowledge about that).

def __del__(self):
    # Cleaning any GeoIP file handles lying around.
    if GeoIP_delete is None:
        return
    if self._country: GeoIP_delete(self._country)
    if self._city: GeoIP_delete(self._city)

Thanks for the research on that issue. I guess that we might have difficulties to come with a test for this, so I suggest to simply add the if GeoIP_delete is None safeguard, and call it a day!

In 35185495e3f70f900b542bf95d744f51e5c5cb92:

Fixed #17066 -- Prevented TypeError in GeoIP.del

When garbaging GeoIP instances, it happens that GeoIP_delete is
already None.
Thanks mitar for the report and stefanw for tests.
