Bump python minimum supported version to 3.10

maflcko commented at 7:26 pm on July 25, 2024: member

All supported operating systems ship with python 3.10 (or later), so bumping the minimum should not cause any issues. A bump will allow new code to use new python features.

For reference:

https://packages.debian.org/bookworm/python3
https://packages.ubuntu.com/jammy/python3
FreeBSD 13/14 ships with 3.11
CentOS-like 8/9 ships with 3.11/3.12 (via appstream)
OpenSuse Tumbleweed ships with all python versions, e.g. https://software.opensuse.org/package/python312-base

This is for Bitcoin Core 29.0 in 2025 (next year), not the soon upcoming 28.0 this fall.

I agree on using newer tools.

A bump will allow new code to use new python features.

Out of curiosity, which features can you mention specifically?

maflcko commented at 10:34 am on August 29, 2024: member

In theory one could use the Python match, which was ported from Rust, IIRC.

Not sure if anyone wants to do that, or if it is worth it. Happy to close this pull instead and do a bump to 3.11 next year instead, which comes with more useful features.

In that case, it might be worth just waiting to bump to 3.11 instead.
