1699753 - (goodbye-py2) [meta] Unsupport Python 2 in mozilla-central

Status: NEW

(Firefox Build System :: General, task, P3)

Description

[Andrew Halberstadt [:ahal]]

We're almost there!

A few tasks under this bug:

1. Delete the py2/py3 linters
2. Remove "py2commands" logic from mach driver
3. Remove logic for a Python 2 virtualenv
4. Remove uses of six and delete the vendored copy of it (this one will likely take a long time, but no rush).

Probably missing a few.

Some of this work (like the mach stuff) can proceed before we finish the ci-py3 metabug as it only impacts things locally.

Bravo :)
It might be an interesting experience to share in a blog post :)

[Andrew Halberstadt [:ahal]]

Yes, I'll definitely publish a retrospective blog post when this is all done.

Let's make this a meta bug.. I think there will be a long tail of "Remove uses of six from X" bugs to be filed.

Comment 5

Callek found https://github.com/asottile/pyupgrade which can automatically remove six compatibility code as well as __future__ imports. It might be worth standing this up as a mozlint linter, but even if not, it'll likely be handy for folks to use manually as part of this bug.

The Bugbug bot thinks this bug should belong to the 'Firefox Build System::Mach Core' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.
