String enums broke in 3.12.0

[WeirdCarrotMonster]

from enum import Enum

class A(str, Enum):
    A = "a"
    B = "b"

with simplejson 3.11.1

>>> import simplejson
>>> simplejson.dumps(A.A)
'"a"'

with simplejson 3.12.0

>>> import simplejson
>>> simplejson.dumps(A.A)
'"A.A"'

That’s unusual, nothing changed in that code path. What version of Python is this?

[WeirdCarrotMonster]

3.6.3

I cannot reproduce this with Python 3.6.3 and simplejson 3.12.0 here:

[serhiy-storchaka]

Python implementation calls str() on the string subclass instance (and this can invoce the custom __str__ method), C implementation uses the string content directly.

       if type(s) is not text_type:
            s = text_type(s)

The json module is not affected.

I've created a test case: https://github.com/WeirdCarrotMonster/simplejson-enum-test.git

@felixonmars There is no problem with archlinux package indeed. Maybe something wrong with PyPI version?

[WeirdCarrotMonster]

Updated tests to check git version: everything works fine. Something is wrong with PyPI package.

[serhiy-storchaka]

Seems there are two bugs here:

1. There is a difference between Python and C implementations.
2. C implementation isn't used in PyPI package.
