A new "contrib" repository for openSUSE

There has been a recent discussion on the opensuse-factory mailing list about the creation of a repository for non-core packages. The concern expressed at the beginning of the discussion is that openSUSE has too many repositories of unknown quality. Right now many openSUSE community members have home repositories with software packages not found in the main openSUSE repository. Some have software that other openSUSE users would like, some have highly experimental packages that most users would rather avoid. It is difficult for the user to find the packages they want, or know which ones they might find suitable. Pascal Bleser expressed some of those concerns:

The goal of the contrib repository must indeed be "stability", which essentially means two things:
- - feature freeze: when the Factory repository is freezed, the contrib repository must be freezed too; only allow bugfix upgrades (as, clearly, I doubt we'd find enough human resources to backport fixes) and reject feature upgrades
- - stable software: packages that are in there need a lot of testing and must hence be picked carefully

The point is to make an "additional" type of repository, not an "always the latest".

And then we should think about how to have those packages tested properly in order to gain an acceptable level of quality in there when openSUSE distro releases happen (or, rather, when they're freezed). Following the alpha/beta/RC cycles of Factory and issue the same calls for testing could be an option.

Alexey Eromenko had some ideas of what that might look like:

Yes, "Contrib" is planned to be a community-driven extension of Factory, with all Factory standards and limits applied.

This means, that user's will have early version of contrib available for 11.1. "early" doesn't mean unstable, but it means that number of packages are expected to be limited.

Only stable software will make it into contrib. All unstable software will remain in user's Home projects in OBS.

Pascal Bleser wondered about how a package is determined to be stable.

Yes, sure, but => "after it becomes stable" <=
That's precisely the point. How do we decide whether a package is stable enough to go into contrib ?
Through a release management team ?
But maybe we need to offer a comfortable way for people to test packages before they make it into contrib, and having a staging repository is one way of doing it.
(I'm just throwing ideas, I'm not saying it's necessarily _the_ way to do it)

Richard Guenther proposed some sort of staging repository.

It as well makes sense to stage Contrib (I would like this for Factory, too, but it's probably easiest to try with Contrib first). If you are familiar with the Debian way then you know there is the unstable and the testing repositories. So there should be something like Contrib:/Unstable (feel free to pick a more suitable name) where a new package (version) should reside for some time before it is migrated to the main Contrib repository. Criterias ideally would be "zero bugs of severity greater than normal" - but of course this would require proper bugzilla integration (or completely manual migration).

Staging Contrib helps getting more peer review and avoids breaking Contrib itself. At the point the next openSUSE is freezed development can continue in the unstable branch but only critical fixes are migrated to Contrib.

Alexey Eromenko that the new repository should have stable versioned branches, but unstable packages should remain in Home repositories.

Speaking about stable/unstable trees: -I think that stable must have braches, yes, (contrib-stable-11.1, contrib-stable-11.2, etc...) - but only for future releases, not backports. Reason is simple: We will find BETA-testers for 11.1/11.2, but unlikely to find enough testers for packages for 10.2.

-unstable: I prefer this branch should exists in user's OBS, but if there are volunteers, it could be part of contrib. Because it is unstable, I don't think it needs branching.

The discussion continued from there. For now unstable packages remain the the user's Home repository and a small review team has been formed to review these potential candidates. The discussion, and results have been documented on the Contrib wiki page, along with a wish list of packages, for those who are interested in learning more about the Contrib repository and the shape it might take.

The interesting thing about openSUSE and it's Build Service is that the barrier of entry is zero. No contributor agreement, no sponsorship required -- in contrast to Debian (the strictest), Fedora and Ubuntu. Unless things have changed since 2007, that is.

If you vet your contributors, then you can afford to trust them a bit more in deciding what's stable and what's not. It's not without fault -- developers are humans, after all. But it's interesting to see what solution openSUSE ends up with.

It's funny how they are constantly reinventing Debian's wheel.
