* Fixed #470 -- Added support for database defaults on fields.Ian Foote2023-05-121-0/+7

* Fixed #34523 -- Fixed TransactionManagementError in ↵Mariusz Felisiak2023-05-031-3/+0
| | | | | | | | | | | | | | QuerySet.update_or_create() with MyISAM storage engine. QuerySet.update_or_create() uses nested atomic to handle possible integrity errors taking savepoints as way to mark back the connection as usable. Savepoints are not returned when uses_savepoints/can_release_savepoints feature flags are set to False. As a consequence, QuerySet.update_or_create() assumed the outer atomic block is tainted and raised TransactionManagementError. This commit partly reverts 331a460f8f2e4f447b68fba491464b68c9b21fd1. Thanks gatello-s for the report.
