Description Miro Hrončok 2020-05-04 12:41:32 UTC
python-flask-autoindex fails to build with Python 3.9.0a6 and 3.8.x:

+ python3 tests/__init__.py
Traceback (most recent call last):
  File "/builddir/build/BUILD/Flask-AutoIndex-0.6/tests/__init__.py", line 9, in <module>
    from flask_autoindex import *
  File "/builddir/build/BUILD/Flask-AutoIndex-0.6/build/lib/flask_autoindex/__init__.py", line 20, in <module>
    from werkzeug import cached_property
ImportError: cannot import name 'cached_property' from 'werkzeug' (/usr/lib/python3.9/site-packages/werkzeug/__init__.py)

cached_property is in the functools module, it should not be imported directly from werkzeug. This used to work just because werkzeug used to import cached_property.


For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.9/fedora-rawhide-x86_64/01365487-python-flask-autoindex/

For all our attempts to build python-flask-autoindex with Python 3.9, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/package/python-flask-autoindex/

Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.9:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/

Let us know here if you have any questions.

Python 3.9 will be included in Fedora 33. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.9.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon.
We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.

Fixed in Rawhide by updating to version 0.6.6.
