Description

cx_Oracle 5.3 causes a few test failures due to this change: "Use None instead of 0 for items in the Cursor.description attribute that do not have any validity."

Sample exception:

  File "/home/jenkins/workspace/django-oracle-master/database/oragis12/label/trusty/python/python3.6/tests/gis_tests/distapp/tests.py", line 262, in test_area
    for i, z in enumerate(SouthTexasZipcode.objects.annotate(area=Area('poly')).order_by('name')):
  File "/home/jenkins/workspace/django-oracle-master/database/oragis12/label/trusty/python/python3.6/django/db/models/query.py", line 242, in __iter__
...
  File "/home/jenkins/workspace/django-oracle-master/database/oragis12/label/trusty/python/python3.6/django/db/backends/oracle/base.py", line 547, in _rowfactory
    elif precision > 0:
TypeError: '>' not supported between instances of 'NoneType' and 'int'

To avoid the chance of a regression in older versions of Django and because the patch isn't completely compatible with Oracle < 5.2 (supported before Django 1.11), we'll document that cx_Oracle < 5.3 is required for Django < 1.11.

Fixed #27924 -- Added support for cx_Oracle 5.3.

  • Fixed Oracle backend due to cx_Oracle 5.3 change in the

Cursor.description behavior i.e. "Use None instead of 0 for items in
the Cursor.description attribute that do not have any validity.".

  • Used cx_Oracle.Object.size() instead of len().

Thanks Tim Graham for the review.
