Description Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2024-04-13 08:45:33 UTC
This package does not support Python 3.12.  Please test it with Python 3.12 as a matter of urgency as the default will change in early June, as per message on gentoo-dev:  Please check the information provided in the tracker.  Ask in #gentoo-python on IRC if need any help.

Firefox-rapid (124+) supports python-3.12 already. ESR (115) does not, and most likely will not. Next ESR (128) will be out around june-july and that has native 3.12 support.

Thunderbird is based on Firefox ESR.

I've just built Thunderbird 115.10.1 with PYTHON_COMPAT_OVERRIDE=python3_12, and it's running without a hiccup; is there anything that I should check/do to better stress compatibility?
These are my USE flags for Thunderbird:

USE="X dbus hwaccel lto openh264 pulseaudio wayland -clang -debug -eme-free -hardened -jack -libproxy (-pgo) (-selinux) -sndio -system-av1 -system-harfbuzz (-system-icu) -system-jpeg -system-libevent -system-librnp -system-libvpx -system-png (-system-python-libs) -system-webp -wifi"
Comment 3 Joonas Niilola gentoo-dev 2024-04-19 15:33:09 UTC
Hmm, thunderbird could work since it doesn't have pgo available. I'll confirm it, thanks for testing!
