* bpo-42901: [Enum] move member creation to `__set_name__` (GH-24196)Ethan Furman2021-01-131-107/+190
| | | | | | | | | | | `type.__new__` calls `__set_name__` and `__init_subclass__`, which means that any work metaclasses do after calling `super().__new__()` will not be available to those two methods. In particular, `Enum` classes that want to make use of `__init_subclass__` will not see any members. Almost all customization is therefore moved to before the `type.__new__()` call, including changing all members to a proto member descriptor with a `__set_name__` that will do the final conversion of a member to be an instance of the `Enum` class.
* bpo-42851: [Enum] remove brittle __init_subclass__ support (GH-24154)Ethan Furman2021-01-071-30/+1
| | | Solution to support calls to `__init_subclass__` with members defined is too brittle and breaks with certain mixins.
* bpo-42727: [Enum] use super() and include **kwds (GH-23927)Ethan Furman2020-12-251-2/+2
| | | | | | | | for multiple inheritance support: use super().new pass **kwds to super().new
* [Enum] EnumMeta.__prepare__ now accepts **kwds (#23917)Ethan Furman2020-12-241-1/+1
|
* bpo-34750: [Enum] add `_EnumDict.update()` support (GH-23725)Ethan Furman2020-12-101-1/+11
| | | | | | | | | | | | | | | | This allows easier Enum construction in unusual cases, such as including dynamic member definitions into a class definition: # created dynamically foo_defines = {'FOO_CAT': 'aloof', 'BAR_DOG': 'friendly', 'FOO_HORSE': 'big'} class Foo(Enum): vars().update({ k: v for k, v in foo_defines.items() if k.startswith('FOO_') }) def upper(self): # example method return self.value.upper()
* bpo-42385: [Enum] add `_generate_next_value_` to StrEnum (GH-23735)Ethan Furman2020-12-101-0/+6
| | | The default for auto() is to return an integer, which doesn't work for `StrEnum`. The new `_generate_next_value_` for `StrEnum` returns the member name, lower cased.
* bpo-42517: [Enum] do not convert private names into members (GH-23722)Ethan Furman2020-12-101-1/+18
| | | private names, such as `_Color__hue` and `_Color__hue_` are now normal attributes, and do not become members nor raise exceptions
* bpo-42567: [Enum] call __init_subclass__ after members are added (GH-23714)Ethan Furman2020-12-101-2/+30
| | | | | When creating an Enum, type.__new__ calls __init_subclass__, but at that point the members have not been added. This patch suppresses the initial call, then manually calls the ancestor __init_subclass__ before returning the new Enum class.
* [Enum] reformat and add doc strings (GH-23705)Ethan Furman2020-12-081-53/+134

* bpo-41907: [Enum] fix format() behavior for IntFlag (GH-22497)Ethan Furman2020-12-081-1/+1

* bpo-41889: [Enum] fix multiple-inheritance regression (GH-22487)Ethan Furman2020-12-071-3/+8
|
* bpo-41816: `StrEnum.__str__` is `str.__str__` (GH-22362)Ethan Furman2020-09-221-0/+2
| | | use `str.__str__` for `StrEnum` so that `str(StrEnum.member)` is the same as directly accessing the string value of the `StrEnum` member
* bpo-41816: add `StrEnum` (GH-22337)Ethan Furman2020-09-221-2/+30
| | | | `StrEnum` ensures that its members were already strings, or intended to be strings.

* bpo-41517: do not allow Enums to be extended (#22271)Ethan Furman2020-09-161-5/+14
| | | fix bug that let Enums be extended via multiple inheritance
* bpo-41789: honor object overrides in Enum classes (GH-22250)Ethan Furman2020-09-151-0/+4
| | | | | EnumMeta double-checks that `__repr__`, `__str__`, `__format__`, and `__reduce_ex__` are not the same as `object`'s, and replaces them if they are -- even if that replacement was intentionally done in the Enum being constructed. This patch fixes that. Automerge-Triggered-By: @ethanfurman

* Remove binding of captured exceptions when not used to reduce the chances of ↵Pablo Galindo2019-11-191-1/+1
| | | | | | | creating cycles (GH-17246) Capturing exceptions into names can lead to reference cycles though the __traceback__ attribute of the exceptions in some obscure cases that have been reported previously and fixed individually. As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles. See for example GH-13135
