[3.9] bpo-41789: honor object overrides in Enum classes (GH-22250) (GH-22272) 
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 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

bpo-31801: Enum: add _ignore_ as class option (#5237) 
* bpo-31801:  Enum:  add _ignore_ as class option

_ignore_ is a list, or white-space seperated str, of names that will not
be candidates for members; these names, and _ignore_ itself, are removed
from the final class.

* bpo-31801: Enum: fix bulleted list format

Ethan Furman 73fc586d9f Add AutoEnum: automatically provides next value if missing. Issue 26988. 2016-08-05 16:03:16 -07:00
Gregory P. Smith ext:(%20%5BGoogle%20Inc.%5D) 6f20bd6063 signal, socket, and ssl module IntEnum constant name lookups now return a 
consistent name for values having multiple names.  Ex: signal.Signals(6)
now refers to itself as signal.SIGALRM rather than flipping between that
and signal.SIGIOT based on the interpreter's hash randomization seed.

This helps finish issue27167.
