* [Enum] improve pickle support (#26666)Ethan Furman2021-06-111-3/+27

| | | | | | | | | | | | | | | | | | | (GH-26649) (GH-26652) This enables, for example, two base Enums to both inherit from `str`, and then both be mixed into the same final Enum: class Str1Enum(str, Enum): GH- some behavior here class Str2Enum(str, Enum): GH- some more behavior here class FinalStrEnum(Str1Enum, Str2Enum): GH- this now works (cherry picked from commit 8a4f0850d75747af8c96ca0e7eef1f5c1abfba25) Co-authored-by: Ethan Furman <ethan@stoneleaf.us> Co-authored-by: Ethan Furman <ethan@stoneleaf.us>

| | | | | | (GH-24155) Solution to support calls to `__init_subclass__` with members defined is too brittle and breaks with certain mixins.. (cherry picked from commit a581a868d97f649aedf868a1d27865a10925c73a)

* [3.9] bpo-42567: [Enum] call __init_subclass__ after members are added ↵Ethan Furman2020-12-151-2/+30
| | | | | | | | (GH-23714) (GH-23772) 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. (cherry picked from commit 6bd94de168b58ac9358277ed6f200490ab26c174)
* [3.9] bpo-42517: [Enum] deprecate private name members (GH-23722) (GH-23748)Miss Islington (bot)2020-12-141-0/+22

* [3.9] bpo-41789: honor object overrides in Enum classes (GH-22250) (GH-22272)Ethan Furman2020-09-161-0/+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.

* 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
