rpm2cpi and Mock on CentOS 7 and 8 cannot handle Fedora 31 SRPM's
by Nico Kadel-Garcia 03 Nov '19

03 Nov '19

Fedora 31 elected to use a new compression algorithm, "zstd", to compress RPM's. The result of this unnecessary optimization is that even commercially supported and long-term-support operating systems, like RHEL 7 and 8, and CentOS 7 and 8, cannot deconstruct leading edge Fedora SRPM's, especially the bleeding edge ones from rawhide. This creates a real backporting problem for people like me who publish internal backports of leading edge components, or who try to publish backports from Fedora to EPEL. It breaks the "mock" toolkit for compiling RPMs under various new operating systems, and it breaks the bility to run "rpmbuild" on a Fedora 31 SRPM. Whether I consider zstd to be an extraneous and entirely unnecessary optimization, it's in place. There are support problems of CentOS taking on supporting an enhanced RPM software to resolve this. Is there any interest in taking this on for centosplus?

CPE Weekly: 2019-11-01
by Aoife Moloney 01 Nov '19

Hi everyone, Welcome to the CPE team weekly project update mail! Background: The Community Platform Engineering group is the Red Hat team combining IT and release engineering from Fedora and CentOS. Our goal is to keep core servers and services running and maintained, build releases, and other strategic tasks that need more dedicated time than volunteers can give. For better communication, we will be giving weekly reports to the CentOS and Fedora communities about the general tasks and work being done. For increased communication between our communities, we have created #redhat-cpe on Freenode! Please feel free to catch us there, a mail has landed on both the CentOS and Fedora devel lists with context here. Note: This document is currently built from individual reports rolled into a google document which we edit and copy into a final document. We are aware that this causes problems with some email readers, and are working on a method to make this less problematic. High Level Project Updates: CentOS: Cbs.centos.org migration Started planning for how to make community builds available with EL8 Deploying a new koji host that will be used for cbs.centos.org migration Migrated following services from puppet configuration management: https://feeds.centos.org (now under ansible, covering CentOS Stream/8) https://planet.centos.org (now under ansible) Continuing conversion of further puppet roles to ansible CentOS CI Added CentOS 8 and CentOS Stream in cico Updated python-cicoclient to support CentOS 8 and CentOS Stream Fedora: F31 was released on Tuesday 29th October! https://fedoramagazine.org/announcing-fedora-31/ F31 documentation was also released. Fedora 31 websites had a harder release, but it is clearer to parties involved the amount of work which was done in the background every release. Fedora Infrastructure freeze ended and so changes to infrastructure can occur until the F32 Beta in about 3 months. Congratulations to everyone in the Community whom were involved with the release, onwards to F32 :) Rawhide Gating: A call to arms email has been sent asking for testers for multi build https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org… Single build workflow is working again and is aligned with multi-build workflows also https://bodhi.stg.fedoraproject.org/updates/FEDORA-2019-3d6e95211e Update for the multi-build workflow needs to be created with autotime on, otherwise the update will not get pushed https://bodhi.stg.fedoraproject.org/updates/FEDORA-2019-90b8bce568 Overview page of the remaining blockers and dependencies organized at: https://hackmd.io/Gbuu9JOPR--Y2yNCBEYI5A?view Ci.centos.org is still not using fedora-messaging Ci-resultsdb-listener with fedora-messaging and support for the new messages format is not deployed in production yet repoSpanner Developed another experimental patch that got us an ~83x speed up. Got 122% performance patch merged. Worked with smooge to get a repoSpanner cluster deployed on realistic cross-datacenter hardware. repoSpanner is still extremely slow when all three DCs are used. Est. 58 minutes to push Bodhi into it, even with the 83x speedup patch. The team is investigating a solution. Application Retirements Elections: Blocking issue was fixed https://pagure.io/fedora-infrastructure/issue/8253 Fedocal : jlanda started to work on communishift port https://pagure.io/fedora-infrastructure/issue/8274 Nuancier: Benson Muite is now working on OIDC authentication - Thank you Benson! Fed-msg: fedmsg-logger equivalent for fedora-messaging https://pagure.io/releng/pull-request/8940 Comments? Suggestions? Feedback? Let Us Know! Have a lovely weekend!

Join us in #redhat-cpe on Freenode
by Leigh Griffin 01 Nov '19

This is originally from Randy Barlow but for time zone reasons I am forwarding this onto the devel list as we will reference it in our weekly update. Thanks Randy for putting this together :) ---- This is a repost from https://blog.electronsweatshop.com/join-us-in-redhat-cpe-on-freenode.html tl;dr; join us in #redhat-cpe on Freenode! Many moons ago, Red Hat merged the CentOS infrastructure team with the Fedora Infrastructure team, into a team known as "Community Platform Engineering" (CPE). Most of the individuals on the combined team have mostly continued to focus on the project they were assigned to before the merger, but as time has gone by we have looked for opportunities to collaborate more. I recently observed that we had been using internal communications to communicate about collaborative projects between CentOS and Fedora infrastructures, rather than public forums. This happened mostly because we've long had internal methods for communicating, and because the collaboration is not particular to either community, so using #fedora-admin on Freenode didn't seem particularly proper either, for example. Thus, this week we have established the #redhat-cpe channel on Freenode as a place for our team to communicate openly about the collaborative efforts we are engaged in. Join us there if you are interested in helping us bring CentOS and Fedora closer together! -- Leigh Griffin Engineering Manager Red Hat Waterford <https://www.redhat.com/> Communications House Cork Road, Waterford City lgriffin(a)redhat.com M: +353877545162 IM: lgriffin @redhatjobs <https://twitter.com/redhatjobs> redhatjobs <https://www.facebook.com/redhatjobs> @redhatjobs <https://instagram.com/redhatjobs> <https://red.ht/sig>
