2023-04-12 - CentOS Public Board Meeting
by Thomas Oulevey 05 Apr '23

05 Apr '23

Hi Everyone, Our next board meeting will take place at 20:00 UTC next week: `date -d "2023-04-12 20:00 UTC"` If you would like to attend please send me an email to alphacc(a)centosproject.org ( please do not reply to @centos-devel or use another email address) and you will receive a link to a Zoom meeting room with a passcode, 1 hour before the meeting takes place. The agenda can be checked at (work in progress) : https://hackmd.io/@centosboard/HyfsgLsZh As a reminder we will enforce few rules : * Wait to be recognized by the Chair before speaking * Respect the Chair when told your time to speak is over - this will allow us to remain on agenda, and complete the meetings in the allotted time * In the event that there are Board-confidential topics, these will be put at the end of the meeting, in Executive Session, and guests will be asked to leave. We hope to minimize these items, but they do sometimes happen. The most common scenarios in which this may happen are personnel issues, or information that Red Hat wishes to share with the Board, but is not yet public. * Muting of participants, or, in extreme situations, ejection from the meeting, is at the sole discretion of the Chair. * Meetings will be recorded, and published to YouTube (possibly with edits/redaction, as approved by the Directors). Thus, by joining the meeting you consent to have your presence at the meeting, and anything you say during the meeting, made public. I hope some of you can join. thanks, -- Thomas 'alphacc' Oulevey CentOS Board of Directors Secretary alphacc(a)centosproject.org

Are non-Red Hat folks not allowed to post comments to CS Jira?
by Miro Hrončok 03 Apr '23

Hello CentOS folks. I've been told "I wanted to leave a comment ..., but I apparently don't have sufficient permissions (it seems to be read only)" about this ticket: https://issues.redhat.com/browse/CS-1502 Is that by design? -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok

RFC (Request for Comments) : future of forums.centos.org
by Fabian Arrotin 29 Mar '23

29 Mar '23

Let's chat about forums.centos.org ! IMHO, that service can be easily moved to a newer OS/PHP stack and so continue to run. But on the other hand, I heard rumors that some forums moderators would like to stop maintaining/moderating it after 2024. I also heard that there is now a centos category on fedora discourse (https://discussion.fedoraproject.org/c/centos/71) So while we (centos infra) can easily migrate that server, should we ? Let's spend some time investigating the options and take a decision about it ! Kind Regards, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]

[Action Required] : Decommissioning (on premises) OpenShift CI cluster
by Fabian Arrotin 29 Mar '23

29 Mar '23

Hi all, Camilla announced this in december already (https://lists.centos.org/pipermail/ci-users/2022-December/thread.html) and we sent multiple reminders about that. The plan was already knew since it was decided to move the whole CI infra to AWS (announced in June 2022) but the last bit that had to move was the openshift CI cluster (aka *.apps.ocp.ci.centos.org) to AWS (https://console-openshift-console.apps.ocp.cloud.ci.centos.org/) As the new cluster in AWS is deployed since end of November you still have to migrate your workload from old to new cluster, and that *before* end of March 2023 (see https://sigs.centos.org/guide/ci/#migration-to-new-ci-instance) We'll continue to send such reminders as long as we see tenants who haven't migrated (yet) We prefer announce it multiple times so that nobody will ask "where is my app gone ?" when the whole cluster will be powered down end of March. PS: if you have already migrated, please confirm to us so that we can already delete your project/namespace/storage PV in the previous cluster. Kind Regards, -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | twitter: @arrfab

RFC (Request for Comments) : future of https://planet.centos.org
by Fabian Arrotin 29 Mar '23

29 Mar '23

https://planet.centos.org was deployed a long time ago to aggregate feeds from various centos contributors and it was migrated from centos release to centos newer release, as planet (python2 based app) was easy to just rebuild. Now that CentOS Linux 7 will go EOL next year, and that https://blog.centos.org/ (linked to SSO) seems to be the only source for blog posts, I'd like to consider just decommissioning that planet instance, and the "Around CentOS" section of www.centos.org homepage would fetch rss feed from blog.centos.org, instead of planet.centos.org (just acting as a MITM these days) Opinions, thoughts ? -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]

RFC (Request for Comments) : future of https://feeds.centos.org
by Fabian Arrotin 29 Mar '23

29 Mar '23

The current situation wrt https://feeds.centos.org is that it was started as a quick/easy way to generate .xml files for RSS feeds, for people willing to just subscribe to some feeds to know when some packages land for Stream 8 and 9 (no mail is sent to centos-announce list for these) It's relying on the `repo-rss` script, from yum-utils, on CentOS 7. But it seems that such tool doesn't exist anymore in dnf-plugins-core (providing yum-utils) and so is absent in CentOS Stream 8 and Stream 9. So the question : should we just stop that service when CentOS Linux 7 will be EOL in June 2024 ? Or are there volunteers to port that tool/script upstream to python3 and have it included in a dnf-plugins-core (or a parallel package in Epel 9) ? -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]

Fedora ELN architecture baseline preparation for CentOS Stream 10
by Brian Stinson 16 Mar '23

16 Mar '23

Hi Folks, The purpose of Fedora ELN is to reflect content from Fedora Rawhide, but built using Enterprise Linux build flags and buildroot configurations. As we prepare for CentOS Stream 10 (and ultimately RHEL 10) we are updating the x86_64 architecture baseline to x86_64-v3 in Fedora ELN [0]. There are no changes to the aarch64, ppc64le or s390x baselines. Your feedback as we make this change is appreciated, and we’re happy to help with any questions. – Brian Stinson and Stephen Gallagher [0]: https://src.fedoraproject.org/rpms/redhat-rpm-config/pull-request/247#reque…

Proposal: CentOS x86 SIG
by Florian Weimer 16 Mar '23

16 Mar '23

# Goals The purpose of this SIG is to quantify the potential benefits of applying existing compiler technology to distribution packages, targeting more recent CPUs, and evaluating different options for how these optimizations can be maintained in a scalable way, and delivered to end users. Today, there is a significant delay between the release of new x86-64 ISAs and the adoption across the entire CentOS distribution. For example, CentOS 9 Stream released with the x86-64-v2 ISA baseline, nine to thirteen years after such CPUs became commercially available. The concern is that this discrepancy leaves more recent CPU features unused, and end users do not see the best possible performance for the CPUs they use. Parts of the distribution are built with run-time selected optimizations, but this only applies to specialized functional areas, such as string manipulation, certain mathematical operations, and cryptography, but not (for example) to language interpreters that are part of CentOS. # Status Proposed: RFC and looking for a sponsoring Governing Board member # What’s in scope * Explore the immediate runtime performance impact of package-specific ISA-related work on key workloads e.g. language interpreters. * Evaluate the performance benefit at run-time of building CentOS with auto-vectorization and the very-cheap cost model and different x86-64 micro-architecture levels. * Explore ways how these performance-enhancing builds can be maintained at the distribution level and made available to end users for installation. * Assess the image/container size impact of those additional optimized builds (this may not be applicable to some delivery mechanisms). * Explore ways to alert users that they do not get optimal performance because of misconfigured hypervisors. * It is possible, but not likely, that work across the entire distribution may be needed to enable shadow stacks. (Userspace enablement happened as part of CentOS 8, but the kernel parts are not upstream and have changed significantly, so there is some uncertainty.) If large-scale work affecting many packages is needed, the SIG would be a natural place to prototype changes before integration into the distribution. # What's not in scope * Enablement for future x86 CPUs and chipsets, assemblers, linkers, and compiler support for new ISAs including regular performance work on individual packages (e.g., identified upstream backports). Hardware enablement must follow existing processes. * Any 32-bit work (such as 64-bit time_t, or a 32-bit kernel) is explicitly excluded. * The focus will be on userspace changes. * Rebuilds for potential observability improvements are out of scope (although shadow stacks are expected to help in this a * Adding additional hosts to the CentOS infrastructure in support of this SIG needs to be negotiated with the CentOS infrastructure team. The CPU microarchitecture level of the existing infrastructure is already sufficient. # Roadmap March 2023: Start the SIG and coordinate with partners April 2023: Adopt existing CentOS builder resources to deliver the required builds. May 2023: Initial performance analysis results. Rest TBD based on results of exploration. Resources They SIG could benefit from spare x86-64 Koji builder capacity.

CentOS Stream 8 is now ahead of RHEL 8
by Adam Samalik 16 Mar '23

16 Mar '23

Hi everyone, I'm glad to announce we have resumed releasing CentOS Stream 8 updates, and that Stream 8 is now following the same workflow as Stream 9. This is a follow up of https://lists.centos.org/pipermail/centos-devel/2023-February/142762.html This means Stream 8 builds will be appearing in the Stream koji (https://kojihub.stream.centos.org) built from sources in the Stream dist-git (https://gitlab.com/redhat/centos-stream/rpms) Mirrors remain the same as before. Individual composes can be found at https://composes.stream.centos.org/stream-8/ We're finishing up cloud and container images, you will find them in the same places as before when ready. Cheers! -- Adam Samalik --------------------------- Principal Software Engineer Red Hat
