* bpo-33947: dataclasses no longer can raise RecursionError in repr (GF9916) ↵Miss Islington (bot)2018-10-191-6/+31
| | | | | | | | (#9970) The reprlib code was copied here instead of importing reprlib. I'm not sure if we really need to avoid the import, but since I expect dataclasses to be more common that reprlib, it seems wise. Plus, the code is small.

* Trivial dataclass cleanups: (GH-6218)Miss Islington (bot)2018-03-241-23/+26
| | | | | | | | | | | | | - When adding a single element to a list, use .append() instead of += and creating a new list. - For consistency, import the copy module, instead of just deepcopy. This leaves only a module at the class level, instead of a function. - Improve some comments. - Improve some whitespace. - Use tuples instead of lists. - Simplify a test.

| | | | | | | | | | 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>

* bpo-32513: Make it easier to override dunders in dataclasses. (GH-5366)Eric V. Smith2018-01-281-82/+224
| | | 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.
