Description Carl George 🤠 2023-03-30 03:22:27 UTC 
Description of problem:
The version of twisted added to EPEL 9 (bug 2049035) is not compatible with the version of attrs in RHEL 9.


Version-Release number of selected component (if applicable):
python3-twisted-22.10.0-1.el9
python3-attrs-20.3.0-7.el9


How reproducible:
always


Steps to Reproduce:
1. python3 -c 'from twisted.trial.unittest import TestCase'


Actual results:
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3.9/site-packages/twisted/trial/unittest.py", line 10, in <module>
    from twisted.trial._asyncrunner import TestDecorator, TestSuite, decorate
  File "/usr/lib/python3.9/site-packages/twisted/trial/_asyncrunner.py", line 19, in <module>
    from twisted.trial._synctest import _logObserver
  File "/usr/lib/python3.9/site-packages/twisted/trial/_synctest.py", line 37, in <module>
    from attrs import frozen
ModuleNotFoundError: No module named 'attrs'


Expected results:
successful import


Additional info:
The attrs namespace wasn't added to the attrs module until version 21.3.0.

https://www.attrs.org/en/21.3.0/changelog.html

It might work to just patch twisted to use `from attr import ...` (the older interface) instead of `from attrs import ...`, but I haven't tested it.
