forums + portal for {lang}.centos.org sites
by Karanbir Singh 17 Aug '24

17 Aug '24

Hi, Earlier in the evening today Ralph, Fabian and I had a chat about the present state of the language subsites. This email sort of summarises the main issue ( s/w ). We seem to have run into a slight technical hitch with punbb/fluxbb. They dont support LDAP as a backend. And we had decided a few months back that all new rollouts must have ldap backend so we can rollin CentOS-DS / openldap based backend. So we need to look at alternatives, and since the primary focus of these international sites is going be forums : Here is a shortlist ( if there is anything else that people are aware of, please add to this list ) - phpBB - SMF - Fudforum - phorum - fluxbb Requirements: - Must be able to scale ( couple of hundred thousand msgs ) - Must be able to handle ldap auth ( if it cant, whats involved in writing the ldap-auth portion ) - Must address the specific requirements raised by the present www.centos.org forum users ( Can you please fill this section in ? ) - Must support all languages we need ( pure utf8 support would be good ) - Secure - Skin'able Nice to have: - Capable of running multiple instances from a single deployment - responsive community :D Things we will need to do: - Decide on what s/w to use. - Give the ArtWork people enough time to get the look & feel sorted. - Migrate newbb forums from www.centos.org to $system ( hey, english is a language too :D ). - Migrate fr.centos.org into the final s/w - setup {de/es/ja/it/pt_br}.centos.org Actions: Ralph and Fabian are going to work on setting up a test ldap server, once that is online we will then start by installing into our test-vm-farm the various s/w to eval them. If anyone would like to help, please feel free to jump right in. I'll setup a wiki page for this issue, which might be a good place to track progress. -- Karanbir Singh : http://www.karan.org/ : 2522219@icq

Using mirrorlist in centos-release-* packages
by Anssi Johansson 12 Sep '19

12 Sep '19

Hi, as mentioned in https://lists.centos.org/pipermail/centos-devel/2018-September/016949.html mirrorlist.centos.org has been updated to produce mirror lists for SIG content as well. Some centos-release-* packages have already been modified to use mirrorlist.centos.org instead of mirror.centos.org, but many still point to mirror.centos.org. Most of mirror.centos.org hosts are also used for seeding the 600+ external mirrors we have. By directing some of their download traffic to external mirrors we can offer faster sync speeds for those external mirrors, and for people downloading individual rpms from mirror.centos.org. Second, most of those external mirrors offer faster download speeds to end users than what could be achieved by downloading from mirror.centos.org, so the users will benefit from this change as well. The better geographical coverage does not hurt either. mirror.centos.org nodes are donated servers, and it would be kind to the sponsors to use their bandwidth sparingly. The .repo files should be modified so that the current baseurl line gets commented out and a mirrorlist entry gets added, like this: mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch… #baseurl=http://mirror.centos.org/$contentdir/$releasever/storage/$basearch/gluster-4.1/ Note that mirrorlist.c.o can automatically choose between main and altarch content based on the arch parameter. The repo names are constructed from the repository path by stripping away the architecture and changing any slashes to dashes: sclo/x86_64/rh -> sclo-rh, sclo/x86_64/sclo -> sclo-sclo, paas/x86_64/openshift-origin311 -> paas-openshift-origin311, storage/x86_64/gluster-5 -> storage-gluster-5 etc. You can use 'curl' to check what mirrorlist outputs for your repository. New repos are added to mirrorlist.centos.org automatically once the repository hits mirror.centos.org. That script is currently run every three hours. I guess it could be run more frequently (it's fairly lightweight), but you should give the external mirrors a few hours to sync before announcing your release anyway. You can either submit an update to your current centos-release-* file now, or wait until you need to create a new centos-release-* package for other reasons such as releasing softwarepackage-(version+1) which uses different paths. My recommendation would be to submit an update to your current centos-release-* package, so that you would not need to worry about this when you eventually need to publish a new one for other reasons. We released an updated centos-release package for CentOS AltArch before 7.6.1810 was released for this exact reason, ie. we didn't need to worry about this change at 7.6.1810 release time. Other people (such as bstinson, arrfab and hughesjr) can probably help with creating and publishing an updated centos-release-* package, but the usual tagging procedure to extras will apply. The SIG Guide https://wiki.centos.org/SIGGuide should have all the needed details for this (if not, complain to bstinson). It is highly recommended to actually test your new centos-release-* package from buildlogs before you ask that package to be signed and pushed to extras. The holiday season is fast approaching so (I) don't expect much activity regarding these changes in the following days. I'm hoping that the SIGs would take a look at this in early 2019, though. Thanks to those SIGs who have already made these changes to their centos-release-* packages! If you have questions, feel free to ask either here or on #centos-devel. Thanks for your time!

Weekly SIG meetings
by Rich Bowen 06 Mar '19

06 Mar '19

I've been noticing, over the last 3 or 4 months, that many of our SIGs are no longer in the habit of holding their (bi-)weekly meetings on IRC. I don't know why this is happening - perhaps they're having their discussions elsewhere, or perhaps there's nothing to discuss. However, I want to remind you that these meetings are a window into your work for the larger community. Your meeting minutes are public, and useful for people who are not directly involved in the SIG but who want to know what's happening. Even a 5-minute status checkin is valuable to our users. I would point you to the excellent example of this from the CBS/Infra weekly meeting, the transcript of which you can see here: https://www.centos.org/minutes/2019/February/centos-devel.2019-02-18-14.02.… Note that there's only one meeting participant, but the meeting is held to offer the opportunity for discussion should anyone need it. Please do get back in the habit of meeting regularly. -- Rich Bowen - rbowen(a)redhat.com @CentOSProject // @rbowen 859 351 9166

Need a knob to disable all spectre/meltdown fixes
by Priya, Nupur 26 Feb '19

26 Feb '19

Hi there, I would like to implement a command , to be able to disable all variants(or at least the ones causing performance impact). As per the RH article: https://access.redhat.com/articles/3311301, we would be able to only disable spectre variant 2 and 3(pti). I need an option to disable variant 1, 3a and 4 as well. Some of the recent articles suggest that options like no_spectre_v1, no_spectre_v2 and spec_store_bypass_disable parameters are available in latest versions of kernel(4.15 and above). https://www.zdnet.com/article/linux-kernel-gets-another-option-to-disable-s… https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html?h… Can this be made available in our Centos 7 kernels? Or is there any plan for RH to implement the same in any future release? Regards, Nupur

Centpkg and the converged git project
by Brian Stinson 22 Feb '19

22 Feb '19

Hi Folks, I've done a bit of work on centpkg, now that we have a testbed at git.stg.centos.org. The goal here is to allow centpkg and fedpkg (Fedora's site) to both understand the different formats. The test version of centpkg described below is the first step in that direction. Basically you can try this out by pulling a container image: `podman pull quay.io/bstinsonmhk/centpkg:develop` Why a container image? - The patches to make this happen involve invasive changes to rpkg, that are still in flight (basically, https://pagure.io/rpkg/pull-request/393) - I wanted to bake in the sources and configs to develop this a little faster as we find problems. What's included, and where to file bugs? - centpkg from: https://bitbucket.org/bstinsonmhk/centpkg/branch/develop - rpkg from: https://pagure.io/fork/bstinson/rpkg/tree/centpkg-inbound - fedpkg from: https://pagure.io/fedpkg/tree/master Here's how I run it for testing CentOS packages (substitute your centos user certificate and a path to RPMs to fit your workstation): `podman run --rm -it -v /home/bstinson/.centos.cert:/home/centpkg-user/.centos.cert:Z -v /home/bstinson/rpms:/home/centpkg-user/rpms:Z quay.io/bstinsonmhk/centpkg:develop` If you're a SIG member, you can push to a sig branch. For example, if I was a mamber of the atomic SIG I could do: # Clone the repo $ centpkg clone -b c7 a2ps # Download the sources from C7 $ centpkg sources # Change to a SIG branch $ git checkout -b c7-sig-atomic-cockpit-preview # Manual push is needed here until we work out a way to register the # new branches $ git push -u origin c7-sig-atomic-cockpit-preview # Upload sources to the SIG branch in the lookaside $ centpkg upload SOURCES/a2ps-4.14.tar.gz SOURCES/i18n-fonts-0.1.tar.gz # CBS does not yet build from SCM, so still need srpms $ centpkg scratch-build --srpm # Try out a fedora branch $ centpkg switch-branch f28 $ centpkg clean # From a Fedora branch this should use your Fedora creds $ centpkg scratch-build # this should work with Fedora's ko What I need help with: - Review the open PRs to rpkg as they come in - Help me find more places where we need to use the new 'Layout' objects (that is where rpkg has paths hard-coded) - Test Fedora workflows, and other commands with centpkg - Help add new commands - to request SIG branches - to translate from one layout to another (ex. bringing a Fedora branch into a CentOS SIG branch) Happy building! --Brian

git.stg.centos.org upgraded to pagure 5.3 (beta) and new feature like mqtt notifications
by Fabian Arrotin 22 Feb '19

22 Feb '19

Hi, In October 2018, we (pre)announced that we were working on a consolidated pagure infra for git.centos.org and src.fedoraproject.org. (https://lists.centos.org/pipermail/centos-devel/2018-October/016997.html) We asked feedback from community and one of the remarks we had was about being able to follow commits for all /rpms/* While there were requests to have that available through pagure API (for people already using the gitblit RPC feature of current https://git.centos.org instance), another idea was to simply send that to a message broker, so that people can just subscribe to that broker on a particular topic and consume the message payloads posted there. As such MQTT support landed in pagure, we decided to upgrade (both instances) and we have (only at the CentOS side) implemented MQTT notifications to a "public" broker Example : This dummy commit (specific branch) : https://git.stg.centos.org/rpms/bacula/c/61cd3575ba64b5f7afbf16eeb5c8dea729… (automatically replicated to https://src.stg.fedoraproject.org/rpms/bacula/c/61cd3575ba64b5f7afbf16eeb5c…) posted the following json message on our MQTT staging broker : git.stg.centos.org/git.receive {"forced": false, "agent": "arrfab", "repo": {"custom_keys": [], "name": "bacula", "parent": null, "date_modified": "1539692831", "access_users": {"owner": ["centosrcm"], "admin": [], "ticket": [], "commit": []}, "namespace": "rpms", "priorities": {}, "close_status": [], "access_groups": {"admin": [], "commit": [], "ticket": []}, "milestones": {}, "user": {"fullname": "CentOS Sources", "name": "centosrcm"}, "date_created": "1539692831", "fullname": "rpms/bacula", "url_path": "rpms/bacula", "id": 6, "tags": [], "description": " Cross platform network backup for Linux, Unix, Mac and Windows"}, "end_commit": "61cd3575ba64b5f7afbf16eeb5c8dea7293b1241", "branch": "c7-sig-altarch-test", "authors": [{"fullname": "Fabian Arrotin", "name": "arrfab"}], "total_commits": 1, "start_commit": "61cd3575ba64b5f7afbf16eeb5c8dea7293b1241"} The first part is just the topic, while the message payload is the json How can you subscribe to that MQTT broker (if you want to automate some workflow) ? The only requirement is to trust our ACO (https://accounts.centos.org) CA cert and also to have your TLS cert from ACO All those steps are done automatically through centos-cert (from centos-packager, see https://wiki.centos.org/HowTos/CentosPackager) From that point, you can use your MQTT client of choice (mosquitto_sub from mosquitto pkg, or python-paho-mqtt for python client, etc) and point to mqtt.stg.centos.org:8883 Simple example with mosquitto_sub : mosquitto_sub --cafile ~/.centos-server-ca.cert --cert ~/.centos.cert --key ~/.centos.cert -h mqtt.stg.centos.org -p 8883 -t git.stg.centos.org/# -v Hope that it helps people willing to get automatic notifications in "real-time" when repositories are created or that there are new commits landing there. Worth noting that it's still only in staging, but once we have a green light, we should migrate git.centos.org to pagure with the same features set as the one deployed on staging. -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 56BEC54E | twitter: @arrfab
