Description Tomáš Hrnčiar 2023-05-09 11:15:08 UTC
notmuch fails to build with Python 3.12.0a7.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/builddir/build/BUILD/notmuch-0.37/bindings/python/notmuch/__init__.py", line 54, in <module>
    from .database import Database
  File "/builddir/build/BUILD/notmuch-0.37/bindings/python/notmuch/database.py", line 24, in <module>
    from .compat import SafeConfigParser
  File "/builddir/build/BUILD/notmuch-0.37/bindings/python/notmuch/compat.py", line 50, in <module>
    from configparser import SafeConfigParser
ImportError: cannot import name 'SafeConfigParser' from 'configparser' (/usr/lib64/python3.12/configparser.py). Did you mean: 'RawConfigParser'?

Several names deprecated in the configparser way back in 3.2 have been removed per gh-89336:
    configparser.ParsingError no longer has a filename attribute or argument. Use the source attribute and argument instead.
    configparser no longer has a SafeConfigParser class. Use the shorter ConfigParser name instead.
    configparser.ConfigParser no longer has a readfp method. Use read_file() instead.

For all our attempts to build notmuch with Python 3.12, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.12/package/notmuch/

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 3.12:
https://copr.fedorainfracloud.org/coprs/g/python/python3.12/

Let us know here if you have any questions.

Python 3.12 is planned to be included in Fedora 39. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.12.
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.
