Oracle Linux chroots (temporarily) available in Fedora Copr
by Pavel Raiskup 17 Jul '23

17 Jul '23

Hello, just a quick note - we enabled Oracle Linux chroots in Fedora Copr today, this is temporarily needed by OAMG/LEAPP team for their CI/CD system. Feel free to test those chroots, but please don't heavily depend on them as we don't know when we'll again drop them (preferably use epel/centos-stream chroots instead, they should provide similar build results).

Excluding older builds of packages from Fedora when testing new ones in Copr
by Miro Hrončok 24 May '23

24 May '23

Hello Copr users and developers. When we update packages in Fedora, we regularly use Copr to test the impact of the upgrade. For me, the procedure usually goes like this: 1) create a new copr with Fedora rawhide x86_64 chroot (and added Koji repo) $ copr create $COPR --repo='http://kojipkgs.fedoraproject.org/repos/rawhide/latest/$basearch/' --chroot fedora-rawhide-x86_64 --delete-after-days 30 2) define and build the updated package in the copr $ copr add-package-distgit $COPR --name $PKG --webhook-rebuild on --commit $BRANCH --namespace forks/$(whoami) $ copr build-package $COPR --name $PKG 3) get the list of dependent packages $ repoquery -q --repo=rawhide{,-source} [--whatrequires $spkg for each subpackage] --recursive | grep src$ | pkgname 4) define and build the depended packages in the copr $ parallel copr add-package-distgit $COPR --webhook-rebuild on --commit rawhide --name -- $(repoquery from above ...) $ parallel copr build-package $COPR --nowait --background --name -- $(repoquery from above ...) 5) analyze build failures, do a "control" rebuild in another copr if needed However, this procedure has a flaw. Let's say I'm working on upgrading python-click from 7.x to 8.x. And let's say a package (even transitively) BuildRequires: python3dist(click) < 8 The way that dnf dependency resolution works, that package will be built with Rawhide's python3-click 7.x and it will be marked as successful. However, I'd like to see a failure here to be notified that such package cannot be build and will be negatively impacted by the update. Is there a way to solve this? I have couple ideas, but none of them is fully working: A) Compose my own repo with the updated package and Rawhide content without it, use that repo in the copr. Pros: - this is similar to what will happen in Koji once the package is updated Cons: - this requires tooling that I don't think exists - this requires a place to put that repo to - the repo creation could take a lot of time and would need to be repeated on-demand each time rawhide changes - Copr's Fedora chroots always include Fedora repos (maybe I can use custom-1-x86_64 chroot?) B) Create a Fedora side tag, explicitly block the package from it, use that side tag's Koji repo. Pros: - same as (A) Cons: - I don't think on-demand side tags allow users to block packages - Copr's Fedora chroots always include Fedora repos (same as (A)) - this wastes Koji's resources a bit - requires waiting for the initial Koji regen-repo C) Block (exclude) python3-click < 8 from the chroot. Pros: - no custom repos required - no resources overhead - no time overhead Cons: - There is no way exclude packages in chroot settings. Mock settings possibly allow me to do this in config_opts['dnf.conf']. - The exclude could obfuscate root.log resolution problems logs. - Packager needs to figure out what exactly to exclude (possibly need to exclude all subpackage's NEVRAs from rawhide compose (and Koji buildroot if they differ)) Is there another way? If not, I think (C) is easiest to actually implement, if the chroot settings page in copr gains an "excludes" option. -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok

Fedora Copr, new Power9 builders
by Pavel Raiskup 19 May '22

19 May '22

Hello all, Fedora infra folks recently racked for a new Power9 machine for Fedora Copr, and we now finished the installation. The new machine is hosting ~30 production builder VMs). This machine is going to replace the two older Power8 boxes. To fixup some startup issues we had to provide a new golden image, so while on it—golden images for all our infrastructure locations were regenerated (all architectures). This is JFYI e-mail, should you have any issues please report them. Happy building! Pavel

Problem with PPC builders
by Steven A. Falco 16 May '22

16 May '22

Over the last few days there seems to be a bottleneck on the PPC builders. For example, please see [1], [2], and [3]. The x86_64 builds all finished promptly, but the ppc64le builds are taking a very long time to even get started. If someone with admin privileges could take a look, I'd appreciate it. Thanks, Steve [1] https://copr.fedorainfracloud.org/coprs/g/kicad/kicad/build/4412264/ [2] https://copr.fedorainfracloud.org/coprs/g/kicad/kicad/build/4412263/ [3] https://copr.fedorainfracloud.org/coprs/g/kicad/kicad/build/4407059/
