* bpo-32953: Dataclasses: frozen should not be inherited for non-dataclass ↵Miss Islington (bot)2018-03-191-24/+75
| | | | | | | | | | derived classes (GH-6147) (GH-6148) If a non-dataclass derives from a frozen dataclass, allow attributes to be set. Require either all of the dataclasses in a class hierarchy to be frozen, or all non-frozen. Store `@dataclass` parameters on the class object under `__dataclass_params__`. This is needed to detect frozen base classes. (cherry picked from commit f199bc655eb50c28e94010714629b376bbbd077b) Co-authored-by: Eric V. Smith <ericvsmith@users.noreply.github.com>

| | | Class authors no longer need to specify repr=False if they want to provide a custom __repr__ for dataclasses. The same thing applies for the other dunder methods that the dataclass decorator adds. If dataclass finds that a dunder methods is defined in the class, it will not overwrite it.
