incompatibility with MySQL-python-1.2.2b1 or python-2.5

[anonymous]

I'm new to Python and Django therefore not sure is it a bug of Django or Python module.
I've installed Python 2.5, MySQL-python-1.2.2b1 and django svn (rev. 3896).
When I run "./manage.py syncdb" - first time it works fine but subsequent runs throw an exception:

$ ./manage.py syncdb
Creating table auth_message
Traceback (most recent call last):
  File "./manage.py", line 11, in <module>
    execute_manager(settings)

    raise errorclass, errorvalue
_mysql_exceptions.OperationalError: (1050, "Table 'auth_message' already exists")

To make long story short, applying the following pathch to django/db/backends/mysql/introspection.py fixes the problem but I guess that it will break it for older versions MySQL-python or python itself and also there should be similar problems in other places of django code

 def get_table_description(cursor, table_name):
     "Returns a description of the table, with the DB-API cursor.description interface."

Please advise how to properly fix this issue.

Apparently MySQL-python-1.2.2b1 does not work properly with MySQL 4.0.
Works fine with MySQL-5.0.24a

[Malcolm Tredinnick]

Since Django does not just support MySQL > 5.0, we need to preferably work around this or at least display a warning. Reopening until we can work out a fix that is sufficiently portable.

Hi Michael, can you please give us a bit of additional information:

• what mysql database version did you use?
• what's the output of 'show create table foo' (for any table that exists)?
• does python-mysql-1.2.2b2 fix it?

Thanks!

It was mysql-4.1.20 (not sure though as it was several months ago).
Sorry I can not reproduce 'show create table' with mysql-4 or check new python module with mysql-4 as I do not have any host with mysql-4 at the moment.

Looks like a bug within python-MySQLdb-1.2.1b1. Please reopen if you can reproduce it with a newer version.
