Description

Django 3.0 and higher do not include django.utils.six, since they've
moved entirely onto Python 3. In order to provide compatibility going
forward, Django Evolution now bundles its own copy of six as
django_evolution.compat.six, and all imports have been updated
accordingly.

Testing Done

Unit tests pass for all supported versions of Python and Django
(1.6 through 2.2 — more work is required for 3.0 support).

Wouldn't it be better to just add a dependency on the upstream six?

chipx86 July 23, 2020, 6:36 p.m.

I debated this. Solid "maybe" with a lean toward "no for now."

We hit that issue before with a system version of six taking precedence from a package, and wrecking havoc when a later system update replaced it with an older version than what some dependency required. I'm a bit weary of system packages outright breaking things for us again because of this dependency.

Makes sense.
