Re: [CentOS-devel] are there any chances to see finished CentOS6 in 2011?

Hi Bill, thanks a lot for your interest. Unfortunately, I'm not in my office at the moment, answering from my cell phone, so please forgive me top posting. I'll come back to you in about 16 hrs, when I'm back in the office. Including you, we're six guys now. Seems very promising! Best regards, Timo -- Urspr.

Von: William Boyle <woboyle(a)ieee.org> Datum: 06.01.2011 18:50 I would be happy to help/test/whatever also. I have an 8 core Intel workstation currently running CentOS 5.5 (w/ Plus kernel). I also have a spare hot-swap system drive to install and test version 6 on, or I can run it in a virtual machine under 5.5. FWIW, Scientific Linux 6 is currently available in beta form. If I can't get CentOS 6 at least in a beta form pdq, then I may be switching to SL instead. Since my wife is a physicist on the computing division staff at FermiLab, at least I know who to gripe at when problems arise!

tracking packages in a Release, through the life of the release
by Karanbir Singh 06 Jan '11

06 Jan '11

hi, one thing that I'd like to do with 5.6 and 6.0 is to have centos-release carry repo info for the debuginfo and the vault repo's for the same Release. For 6.0 it would be fairly slim to start with but for 5.6 it could look like this : Enabled by default: [base] [updates] Available, but not enabled: [5.5] [5.5-updates] [5.4] [5.4-updates] .. [5.0] [5.0-updates] Allowing people to get specific packages from anywhere in the Release's past. the baseurl for these will point at vault.centos.org/ Similarly would be the debuginfo .repo's. For /5/ we have a single debuginfo repo, for /6/ we can, and i think we should, split these up into repo's that match the release's. so 6.0's debugs end up in debuginfo.c.o/6.0/ and 6.1 goto d.c.o/6.1/ etc. Just as with the older release's .repo files - these would be present but disabled. Also, I'm trying to plumb in debuginfo signing. But it might end up being a different key to the main distro signing key[1], cross signed by the distro key and master keys. lets see how that pans out. thoughts ? - KB

Closing out CentOS 6 Bugs
by JohnS 06 Jan '11

06 Jan '11

Karanbir, Can you look into closing out the bugs that can be closed etc? Can also [1,2] be looked into to confirm package depends on abrt / report (hidden gotchas). Look at the example spec file at the changes that are required and the level of them that the Application Backend will have to support. Is there someone that can take on the App Server end? Also needed to know if you are symlinking from "redhat-release" to "centos-release" or not. That depends on how other packages need to be patched, ie "lsb_release".

CentOS-6 repositories: *-devel, *-debuginfo, contrib-{unstable, testing, stable}
by Brian Schueler 05 Jan '11

05 Jan '11

Hi, As I have seen there is only a subset of development libraries included on the upstream's el6 DVD. While packaging my additional software with mock I needed to put some distro SRPMs into my local SRPMs directory to get the *-devel pkgs. (But it would make no sense when the distro packages are updated.) Will be there all *-devel packages included in the CentOS-6 [base]/[update] repositories and will be there a *-debuginfo repo, too? What about contributer repositories? My idea is to have 3 stages of user contrib repositories (two of them controlled by the CentOS dev team): [contrib-unstable] where everyone may upload software packages via web (requiring only a simple registration), that are not well tested and not targeted to a production system. [contrib-testing] packages that have been selected by the developer team that needs to be tested. [contib] packages that are fully tested and confirmed to be stable and which does not have any side-effects to the CentOS base installation. All these points would make C6 fantastic for everyone (for engineers, developers, administrators, end-users and even artists). Cheers, Brian.

rhel-6 rebuild summary
by Farkas Levente 04 Jan '11

04 Jan '11

hi, i write this mail after more people ask me in private. and since the centos core devel team not share any info about it's build system, status, there modifications, doesn't have any public revision system and not really accept any help or advice for outside. but i still believe these are useful info for many others so i try to summarize our rhel-6 rebuild experience. first question is the build host and base repo selection. it's advice to choose both the build system and the base repo as close as to rhel-6 as possible. unfortunately even with official rhel-6 isos you can't get the optional packages in binary. so imho the best base system and base repo is a union of rhel-6 rc2 and rhel-6 beta. both are available freely in binary but only the beta include the optional packages in binary from. after you finish you can rebuild packages on itself again. another important note that most update packages (there're a few dozens) have higher buildreq packages then in the base repo, but these buildreqs are not versioned in the specs. so you've to add the updates pacakges to the build system's base packages otherwise you'll get build errors. i recommend mock-1.1.7 for building. unfortunately at rh it's not required to be able to build src.rpm is mock, they use only rpmbuild (!) which of course cause a few dozen of packages won't build:-( imho it'd be useful something like this for rhel too: http://fedoraproject.org/wiki/FTBFS so let we see what's are the problematic packages (fortunately most of the packages build clean). all of these packages bellow has a bugzilla entry and most of them already contains the solutions. so just go and search for it (i'd not like to link all bz entry:-() - virt-top (missing ocaml-camomile-data) - spice-client (missing pixman-devel) these two packages can't be rebuild on rhel-6 since they has such buildreq which is not shipped in rhel-6 (simple rh forget about it:-) so you can either add to the base repo these packages from epel or from a rebuild from fedora or simple drop them. - bash - zsh can't be rebuild in mock-1.x since a mock tty bug. in this case imho the easiest solution: mock <params> --rebuild bash... ctrl-c during build, then mock <params> --shell rpmbuild --rebuild /builddir/build/originals/bash... - nss can't be rebuild in mock since during %check try to connect to the localhost to test ssl, but it's not working in mock. i suggest the above solution plus ctrl-c during the rpmbuild when the build hang at the ssl connection test and after the you'll got a successful build:-) - kernel unfortunately kernel spec is not updated to the new noarch subpackage style. which means you've to build the arch and noarch packages separately (as in rhel-5). but the new spec file even worst then the rhel-5 was so eg: a simple: mock <params> --target "noarch,i686" --rebuild kernel... no longer works, but mock <params> --target "noarch" --rebuild kernel... mock <params> --target "i686" --rebuild kernel... works:-) imho the best would be to update the kernel spec to the new noarch style subpackage, but afais rh so conservative about kernel spec it won't be happened in the rhel-6.x series:-( - opal has a wrong rh patch which cause ekiga not compile, so you've to fix opal first. - java-1.6.0-openjdk-1.6.0.0-1.21.b17.el6 can't be build, unfortunately bz with fixes for this package are not public, but there's an update which can be build (may be we'd have to leave this package out). and the remaining packages has different problems in the spec file, but all has (mostly a simple) solution in bz, but doesn't have update package: - guile - openmpi - foomatic - hivex - mod_auth_kerb - gnome-doc-utils - pilot-link - linuxdoc-tools - perl-Sys-Virt - perl-Test-MockObject - perl-Test-Memory-Cycle - perl-GSSAPI - perl-Makefile-Parser - perl-CGI-Session - perl-IPC-Run3 - python-lxml - python-sqlalchemy - rome - epydoc - kdepim-runtime i hope it can help for a few poeple. anyway happy xmas! -- Levente "Si vis pacem para bellum!"

looking to help out
by Kenneth Armstrong 04 Jan '11

04 Jan '11

Hi, I was wondering if there was a "getting started" guide of sorts on how to help out with the project? I'm a sysadmin by trade, but my developer skills are a bit weak. Is there a way that I could help with anything? I would like to learn how to do packaging and such, and how to search for upstream branding stuff and repackage a file, as that seems like something I could probably start out with. Thanks. -Kenny

That would be great of you could pass on your links for packaging. I would be very interested in trying my hand at that. Thanks!

Hi Kenny Here is a great starting place http://wiki.centos.org/Contribute Helping in IRC or the forums and participating on the mailing lists is a great start. If you are interested in packaging I have many links for that as well that have been passed on to me by CentOS people that will help you get started with that as well, if you are interested. -- LostSon http://lostsonsvault.org _______________________________________________ CentOS-devel mailing list CentOS-devel(a)centos.org http://lists.centos.org/mailman/listinfo/centos-devel

Collecting data
by derleader __ 24 Dec '10

Hi, I'm developing C plugin for Centos which will be installed as kernel module. The problem is how to collect the data about: CPU Check – Utilization, Model, Number of Cores RAM Check – Total Memory, Free Memory, Memory Load HDD Check – Number of physical HDDs, Number of logical partitions, Total space, Free space Running processes – Total number of processes Logs – system logs such as error logs System uptime Users logged in and last login – total list of users Total network connections Check hardware parts model and number The kernel module will check the status of the OS every 5 minutes. What is the most efficient way to collect these data? Regards Peter
