With oslo.db 12.1.0 the following sqlalchemy warning become an error: sqlalchemy.exc.RemovedIn20Warning: Retrieving row members using strings or other non-integers is deprecated; use row._mapping for a dictionary interface to the row (Background on SQLAlchemy 2.0 at: https://sqlalche.me/e/b8d9) We tried to fix this before but missed a test_case that still used dict access to get the fields of a Row instead of attribute access. We fixed that test here. Also while fixed it I noticed that the generic _AttributeCache object states that it stores dicts but actually it sometimes stores dict but sometimes it stores Row objects. So the doc is updated and the dict path converted to store namedtuple objects in the cache instead. Note that Row is also acts like a namedtuple except that ._mapping does not exists in namedtuple but exists in Row. The trait object assumed it gets a Row object with ._mapping from the cache so that is adjusted to only assume a namedtuple and use _asdict() to covert it to dict which is available both in Row and namedtuple.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
