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

[Copr] Turning off AppStream metadata generation
by Jiri Kyjovsky 13 Mar '23

13 Mar '23

Hello everybody, due to problems with appstream-builder, we decided to disable it on all current projects, because it is very I/O demanding [1] and will timeout on our disks even on medium-sized projects, which often leads to failed builds. Please let us know if you want us not to turn off the appstream-builder for you. Or you can turn it back on again in project settings once we announce we disabled it on all projects FTR, since the last release, we no longer enable appstream metadata for new builds by default, so this warning applies to projects older than 2023-01-25 Jiri [1] - https://github.com/hughsie/appstream-glib/issues/301

Copr will disable generating sqlite databases for repositories soon
by Jiri Kyjovsky 13 Mar '23

13 Mar '23

Hello, To save some disk space, we are disabling generating sqlite databases for repositories which we think is not necessary [1]. I believe that it should not affect you, but we published this change to our stg instance [2], so you can try whether this change won't break your projects on certain chroots. The PR changing this - https://github.com/fedora-copr/copr/pull/2570 Jiri [1] - https://github.com/fedora-copr/copr/issues/1171 [2] - https://copr.stg.fedoraproject.org/

Can a Copr group be migrated to a different FAS group?
by Miro Hrončok 08 Mar '23

08 Mar '23

Hello, we have recently migrated our packaging use case from the python-sig FAS group to python-packagers-sig. Is it possible, perhaps by adjusting the datat in the database, to migrate the copr @python group from python-sig to python-packagers-sig FAS group? Thanks. https://copr.fedorainfracloud.org/groups/g/python/coprs/ -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok
