29721	Migrations are not applied atomically	Gavin Wahl	Sanyam Khurana	"Migrations run the migration and record that the migration was applied in a different transaction. This results in a broken/inconsistent database when an error or crash happens between those two steps. This is not purely theoretical, it has happened to me.

The executor needs to call migration.apply and record_applied in the same transaction, and then the django_migrations table can't get out of sync with the migrations that have actually been applied. I think this could be done by moving the call to record_applied inside the schema_editor context manager block."	Bug	closed	Migrations	2.1	Normal	fixed			Ready for checkin	1	0	0	0	0	0
