Hi everyone, I'm orphaning deltarpm because, as it's currently used in Fedora, it's not very effective, bugs keep getting opened against it because it's not working as well as it should (mostly an infra issue as opposed to a problem with the tool itself), and I no longer have the time or motivation to deal with these tickets when it seems like there's not much benefit. The main problem with deltarpms is that we don't keep them from compose to compose, so we're only getting the previous day's deltarpms when we download updates. This means that the only way you'll be able to truly take advantage of deltarpms is if you get updates after every compose. For more details, see: https://pagure.io/releng/issue/7215 Bugs that need to be looked into: https://bugzilla.redhat.com/show_bug.cgi?id=1873876 - This is mostly two different problems: 1) when the zstd algorithm changes, deltarpms cannot be rebuilt to the exact same RPM, and 2) deltarpms for the kernel package seem to be impossible to rebuild to the exact same RPM due to the compression format used on the kernel RPMs https://bugzilla.redhat.com/show_bug.cgi?id=2058477 - No idea why 100+ MB of packages failed to build correctly (no logs in the ticket), but it's probably related to (1) above. A brief history of how deltarpms came to be added to Fedora: https://www.jdieter.net/posts/2013/05/31/eulogy-for-yum-presto/ Finally, I want to say a huge thank you to Michael Schroeder, who wrote deltarpm. The tool itself still works beautifully well, and the issues we're seeing are all infrastructure related. I also want to say thank you to everyone who worked on getting deltarpms into Fedora in the first place and who have helped keep them running this long.
