New description:
When running unit tests, the internal testing of a db for using
transactions breaks when using MySQL Cluster server v8.0.28 because that
db version requires a primary key for tables, and this line in
https://github.com/django/django/blob/main/django/db/backends/base/features.py
breaks it :
{{{
@cached_property
def supports_transactions(self):
"""Confirm support for transactions."""
with self.connection.cursor() as cursor:
cursor.execute("CREATE TABLE ROLLBACK_TEST (X INT)")
}}}
We have been patch-fixing that file as follows:
<- cursor.execute("CREATE TABLE ROLLBACK_TEST (X INT PRIMARY
KEY)")
---
-> cursor.execute("CREATE TABLE ROLLBACK_TEST (X INT)")
