DisabledRepos and Software Center

I have question about https://fedoraproject.org/wiki/Changes/DisabledRepoSupport We (as Copr developers) are thinking about one RFE. We would like to create package which would contains .repo files and gpg keys for every Copr project. All of them with enabled=0 enabled_metadata=1 But I wonder what would be user experience? There would be no change for pure DNF users, but what about users of Software Center. What if there are multiple instances of the same application in several Copr project? What if the same application is already in Fedora? For example: Gimp. There is one in Fedora. Let assume there would be Copr project which rebuild Gimp with e.g. TIFF support disabled another project with Copression routines disabled. They can have higher or lower version. How will Software Center decide (or offer user) which version from which repository will be installed? I am especially courious about those scenarios: 1) Application is in Fedora, 3rd party repo (disabled, but metadata enabled) contains the same application with bigger NEVRA. 2) Application is not in Fedora, there are multiple 3rd party repos (disabled, but metadata enabled) which contains various version of the same Application. -- Miroslav Suchy, RHCA Red Hat, Senior Software Engineer, #brno, #devexp, #fedora-buildsys
