I've noticed it takes quite a while on the kernel builds, and I'm curious what factors influence how long the script takes. Is it number of binaries, binary sizes, etc? -Tom _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx <mailto:devel@xxxxxxxxxxxxxxxxxxxxxxx> To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx <mailto:devel-leave@xxxxxxxxxxxxxxxxxxxxxxx> Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ <https://docs.fedoraproject.org/en-US/project/code-of-conduct/> List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines <https://fedoraproject.org/wiki/Mailing_list_guidelines> List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx <https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx> Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure <https://pagure.io/fedora-infrastructure> Hey Tom, Unfortunately no, a potential increase in build time was not taken into account at the time of the implementation of this change, as it never came up when considering other buildroot policy scripts as well. Here is the actual script that runs: https://github.com/rpm-software-management/rpm/blob/rpm-4.16.x/scripts/check-rpaths-worker <https://github.com/rpm-software-management/rpm/blob/rpm-4.16.x/scripts/check-rpaths-worker> Could you try and compare two scratch builds? One as is and one by adding |%global __brp_check_rpaths %{nil} |at the SPEC?| |
Instead of doing two scratch builds, I just added: %global __brp_check_rpaths time /usr/lib/rpm/check-rpaths to the spec file and did a scratch build[1]. The results on x86_64 were: real 13m51.517s user 8m53.216s sys 7m34.105s Overall build time for the scratch build was 88m37s, so that means check-rpaths accounted for 15% of the build time. I'm going to do some more tests on some of the larger packages I maintain (llvm and clang) and see what the impact is. I do think it would be worth trying to profile the script and see if there is room for optimization. - Tom [1] https://koji.fedoraproject.org/koji/taskinfo?taskID=70270039
Also adding here for completion that the script will also check for RUNPATH as of rpm 4.17: https://github.com/rpm-software-management/rpm/pull/1487/files <https://github.com/rpm-software-management/rpm/pull/1487/files> -- Regards, Charalampos Stratakis Senior Software Engineer Python Maintenance Team, Red Hat _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
