Document that Django doesn't work with MySQL under Python 3

[rajeevramdas@…]

I am trying to use the Django with experimental Python 3 support on Linux.
I have installed MySqldb for connectivity with Mysql. (I have used the MySqldb with the python 3 support, from ​https://github.com/davispuh/MySQL-for-Python-3)
When i run python manage.py syncdb it gives me the following error.

python manage.py syncdb
Creating tables ...
Creating table auth_permission
Creating table auth_group_permissions
Creating table auth_group

DatabaseError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%s AND django_content_type.app_label = %s )' at line 1")

Yes, it is known that the MySQL support for Python 3 is not yet ready in Django, mainly because the official MySqldb has not migrated to Python 3.

Let's keep this as a TODO reminder or as a documentation ticket to specify that Django-Python3-MySQL is not supported yet if we don't make it before 1.5 release.

We're about to release 1.5.

We should say that MySQL is unsupported in the "Python 3 support" paragraph of the release notes.

Does anyone know if Oracle works? cx_Oracle supports on Python 3, but I don't know if we ever ran the test suite with Oracle and Python 3.

Another important current limitation to document is PIL (no ImageField on Python 3). Our best hope for a Python 3 port is with ​https://github.com/python-imaging/Pillow.
