[gentoo-dev] Policy-level discussion for minimum versions on dependencies
-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Hi all... Mozilla had a bug recently ( http://bugs.gentoo.org/show_bug.cgi?id=489838 ) that I think has much wider implications for all packages, and I would like to discuss how to best address this. The synopsis of the situation is that the latest firefox ebuild now depends on icu, specifically icu-50.1 or above. When this version of firefox was added to the tree, the lowest version of icu in the tree was icu-51.0 -- in fact, icu-48 through icu-50 were dropped from the tree about 2 months prior to the new firefox being added. The bug that was filed, is that a user didn't do a full emerge -uDN @world prior to emerging (upgrading?) firefox, and they had icu-49 already installed. Because the firefox dep didn't have a minimum version, portage didn't see upgrading icu as a requirement before firefox emerged. I fully agree with the user and other commenters on the bug, that after --sync'ing a user should be able to 'emerge [-u] firefox' and all necessary dependency updates would be applied. However, it's been a long-standing general practise that if there are no deps in the tree older than what is necessary for a package, that package doesn't need to have a minimum version on the dependency atom. As such, issues similar to this are probably lying in wait all other the place in the tree. To mitigate this, i see three possibilities: 1 - make it clear in documentation for end users that they need to emerge -uDN @world after a --sync, otherwise they may see breakage and if they do it's not a bug when an emerge -uDN @world fixes it. IMO this is not a desirable solution but it best matches what is unofficially required now. 2 - make a policy for developers that they need to add minimum versions on dependency atoms so that their package will trigger dependency updates, for all dependencies that have in the last year (**) had a version in the tree older than what the package needs. This is the most correct solution, but requires all devs to do the work. 3 - change portage behaviour s.t. somehow when resolving dependencies it does not consider installed atoms that are missing from the tree to be valid at satisfying a dependency of a package. This would resolve the issue without dev's as a whole needing to do anything different, but would also have unforseen consequences since this is a major behavioural change for portage's dependency resolution.

I agree with this sentiment. It's always been my view that the needs of a package are driven by the package itself, not by the tree. Rationale: A package will build and run as long as it's own requirements are met regardless of what the tree states. We have layman overlays and user's own overlays. Whilst these are not 100% supported by Gentoo they are not banned either. They are also not barely tolerated, it's more a case of overlays are not a problem and users are welcome to use them as long as they don't conflict with or break the tree for that user. This needn't be onerous. Presumably ebuild maintainers read the README and Changelog, these often state the versions of deps the package supports. Take that information and put it in the ebuild. Maintainers are under no obligation to provide the absolute minimum version of a dep, only at least one that will work. If the user decides to make other versions available to his system by whatever means, then portage can deal with it by and large transparently. -- Alan McKinnon alan.mckin...@gmail.com
