Red Hat will be supporting Python 2.6 until 2020'ish, Python 2.7 until at least 2024 (since RHEL7 isn't actually out yet). Python 2 is part of one of our core products (RHEL), and a dependency of another one (OpenStack). While the wheels are in motion upstream to migrate both to Python 3, that's a long term project in both cases, and really hard to make a business case for. While we do believe the open source way delivers better software in the long run, we still have to make our case when we want the company to spend time and resources on something. > As responsible maintainers, we should just advise our users that > Python 2.7 is a dead horse, and that they should stop riding it. > More professionally, we should set an official end-of-life date > for 2.7 (alas, we should have done that two years ago). This completely ignores the practical realities of commercial software development, and the commitments that vendors have made to their customers. I agree it would be completely unreasonable to ask volunteers to contribute their own time to making this proposal work. However, it's likely to be much easier for those of us with influence in the commercial world to shake some resources loose if we have a pre-arranged agreement on the specific help we need to better support their interests. > I hope that the language summit can agree to stopping bug fix > releases for 2.7 in 2014. I'd rather come up with a plan to seek dedicated resources from key corporate users to help with the boring parts of long term maintenance that are really hard to get volunteers excited about, but make a great avenue for corporate sponsored contributions without infringing on the upstream community's autonomy.
