Description
What version of protobuf and what language are you using?
Version: 3.19.6
The line that sets the docstring is present in the current release (22.1) and main, so I suspect that they will also be affected:
Language: Python
What operating system (Linux, Windows, ...) and version?
Fedora Linux Rawhide/39, plus experimental Python 3.12: https://copr.fedorainfracloud.org/coprs/g/python/python3.12/
What runtime / compiler are you using (e.g., python version or gcc version)
Python 3.12.0a5, GCC 13.0.1
What did you do?
Steps to reproduce the behavior:
- Build the pure-Python version of the Python protobuf extension.
from google.protobuf import descriptor_pb2
This import occurred in the generated proto bindings in googleapis-common-protos; see downstream bug https://bugzilla.redhat.com/show_bug.cgi?id=2176158.
What did you expect to see
Successful import with no output.
What did you see instead?
