* bpo-33141: Have dataclasses.Field pass through __set_name__ to any default ↵Eric V. Smith2018-03-261-0/+42
| | | | | argument. (GH-6260) This is part of PEP 487 and the descriptor protocol.
* Minor fixes to dataclass tests. (GH-6243)Eric V. Smith2018-03-261-42/+41
| | | Also, re-enable a test for ClassVars with default_factory.
* Trivial improvements to dataclasses tests. (GH-6234)Eric V. Smith2018-03-251-2/+3

* Fix invalid escape sequence: use raw string. (GH-6225)Eric V. Smith2018-03-251-1/+1

* bpo-32505: dataclasses: raise TypeError if a member variable is of type ↵Eric V. Smith2018-03-221-0/+43
| | | | | Field, but doesn't have a type annotation. (GH-6192) If a dataclass has a member variable that's of type Field, but it doesn't have a type annotation, raise TypeError.
* Add 'Field' to dataclasses.__all__. (GH-6182)Eric V. Smith2018-03-211-4/+5
| | | | - Add missing 'Field' to __all__. - Improve tests to catch this.
* bpo-32896: Fix error when subclassing a dataclass with a field that uses a ↵Eric V. Smith2018-03-211-0/+49
| | | | | default_factory (GH-6170) Fix the way that new annotations in a class are detected.
* bpo-33100: Dataclasses now handles __slots__ and default values correctly. ↵Eric V. Smith2018-03-201-0/+42
| | | | | (GH-6152) If the class has a member that's a MemberDescriptorType, it's not a default value, it's from that member being in __slots__.
* bpo-32953: Dataclasses: frozen should not be inherited for non-dataclass ↵Eric V. Smith2018-03-191-24/+75
| | | | | | | derived classes (#6147) 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.
* bpo-32960: For dataclasses, disallow inheriting frozen from non-frozen ↵Eric V. Smith2018-02-271-23/+61
| | | | | classes and vice-versa, (GH-5919) This restriction will be relaxed at a future date.
* Fix 'deecorator' typo in test/test_dataclasses (GH-5899)Terry Jan Reedy2018-02-261-1/+1

* bpo-32929: Dataclasses: Change the tri-state hash parameter to the boolean ↵Eric V. Smith2018-02-261-116/+124
| | | | | unsafe_hash. (#5891) unsafe_hash=False is now the default. It is the same behavior as the old hash=None parameter. unsafe_hash=True will try to add __hash__. If it already exists, TypeError is raised.
* Exhaustively test dataclass hashing when no hash= value is provided. This is ↵Eric V. Smith2018-02-231-0/+73
| | | | in anticipation of changing how non-default hashing is handled. (#5834)
* Fix trivial typo in test_dataclasses.py. (GH-5398)Eric V. Smith2018-01-291-1/+1
|
* bpo-32513: Make it easier to override dunders in dataclasses. (GH-5366)Eric V. Smith2018-01-281-212/+452
| | | 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.
* bpo-32279: Add additional params to make_dataclass(), pass through to ↵Eric V. Smith2018-01-061-0/+17

| | | | (gh-5115)
* bpo-32499: Add dataclasses.is_dataclass(obj), which returns True if obj is a ↵Eric V. Smith2018-01-061-16/+21

* bpo-32427: Expose dataclasses.MISSING object. (#5045)Eric V. Smith2017-12-291-3/+49

* bpo-32259: Make a TypeError message when unpack non-iterable more specific. ↵Serhiy Storchaka2017-12-261-1/+1

* bpo-32297: Few misspellings found in Python source code comments. (#4803)Mike2017-12-141-1/+1
| | | | | | | | * Fix multiple typos in code comments * Add spacing in comments (test_logging.py, test_math.py) * Fix spaces at the beginning of comments in test_logging.py
* Use raw strings for regex to avoid invalid escape sequences. (GH-4741)Eric V. Smith2017-12-061-2/+2
