zypper plugin for discovering reverse dependencies

Updated almost 2 years ago. 10 hacker ♥️. 5 followers.

Often when we test maintenance updates or when we decide to push an update for a package we want to know what that change may cause. Right now it is really difficult to figure out what package depends on a given package.

Motivation

When I was looking for orphan packages in SLE or in openSUSE what could start maintaining I was looking for low risk packages. Naturally for a less experienced package maintainer it is comforting to know that the package they start making updates for is not going to mess up hundreds of other packages. So when choosing a package to maintain it would be handy to know what other packages depend on the given package. Also when we are doing maintenance update validation for SLE it would be nice to know what other packages we should test with more attention. We test user scenarios and the whole platform, but if a package X depends on package Y and package Y gets a maintenance update then maybe it is a good idea to test the package X with extra attention.

Goal

  • Refresh a bit the rdepends project
  • Create a new project under the zypper development project in the Open Build Service
  • Push an initial version of a working prototype
  • Figure out if the plugin can be done in python without executing the zypper itself

      You might want to look at dnf's repoquery command, which supports exactly this use case. (And you can actually use dnf against openSUSE & SLE repos)

        Thank you for the idea Dan. I will check it out. I am coming from Debian and Ubuntu and there is apt-cache rdepends command for this purpose.

        Or use the zypper se --requires-pkg functionality ;). It is not recursive though so it only checks the reverse deps of the given package
