Allowing Epoch to be reset between releases (Was: On not bumping the epoch in ceph-14, f30 and f31/rawhide)

One thing to consider here is other packages that have Requires etc. on something like "foo > 1:1.2", so if it is automated, this part needs to be automated as well. If we do this, we might have a "flag day" but not automated for all 756 packages, but opt in. Aka we create a window on rawhide, and packagers would sign up for this, we announce the window, let them do it, and we close the window... ? This needs a lot of consideration for sure, but I think it can be done somehow. However I'm not sure it's worth the effort. -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok ___ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org

Koji uses NVR as a key > (without Epoch), and OBS freely allows EVRs to go up and down. Some parts of Koji do rely on epoch not doing down. Notably, koji-shadow uses epoch and it will stop working correctly when epoch is removed or decreased. koji-shadow is not currently used by Fedora project, but it may be used in future to bootstrap new architectures. And it is still used by third parties to rebuild Fedora packages. -- Mikolaj Izdebski ___ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org

Just a note that we do have plans to use Bodhi to manage Rawhide in the future, and will hopefully have it doing this in 2019. Bodhi is not currently Epoch-aware, but I wouldn't be opposed to teaching it about Epochs if we wanted to make a change in this area. signature.asc Description: This is a digitally signed message part ___ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
