Hi! during the Tuesday's Modularity WG meeting I was talking about the status of the Base Runtime prototype build and the package build failures we encountered during our latest attempt. The meeting log is here: https://meetbot.fedoraproject.org/teams/modularity_wg/modularity_wg.2016-11-29-15.00.log.html In short: To bootstrap the Modularity infra (yeah, it's still not done) we took a (fairly large) set of packages directly from Fedora 25 RC3 and put them all in one, self-hosting module, currently misleadingly labeled as base-runtime. The next step was to rebuild this set using only the packages in it, preferrably twice, to prove it works, produces the same, reproducible builds (or as close as we can get) and to save us from sudden, unexpected breakage later when we need to touch components deep in the [build] dependency chain. (Since this is a common question: No, the final Base Runtime module, or the Generational Core stack it is part of, won't be self-hosting and we won't be shipping the entire set we're currently working with under that name.) We attempted to rebuild 2943 SRPMs and encountered 152 failures. The reasons vary and include undiscovered conditional build dependencies, undeclared build or runtime dependencies in combination with recent buildroot and other package dependency chains changes, packages no longer being compatible with their updated dependencies, random hangs or non-deterministic, randomly failing test suites, to name a few. Some but not all of those affect, and can be reproduced in, the traditional Fedora release, too, and fixing these issues is not only crucial for the upcoming modular Fedora 26 Server but will benefit the standard Fedora release as well. We'll be working on resolving these failures during the upcoming few weeks -- via FTBFS bug reports or immediate fixes in the most trivial cases. We'll use the following tracker bug for this purpose: https://bugzilla.redhat.com/show_bug.cgi?id=1400162 For the curious, the logs are here: https://psabata.fedorapeople.org/f25rc3-failures/ And the modulemd input for this build is here: http://pkgs.stg.fedoraproject.org/cgit/modules/base-runtime.git/tree/base-runtime.yaml?id=d2485512c7916304e73fabc5db422798eb2be1d5 If you maintain some of these FTBFS'd packages, feel free to fix them even before we get to you! :) Just, please, let us know if you do. Finally, some quick test instructions: Make sure your package builds in F25 and Rawhide. If it does, check whether it also builds in mock using this configuration file: https://paste.fedoraproject.org/494173/ If it works there as well, chances are it's fine. Thank you in advance, P
