Domain names

• buildroot.org
  • Sponsored by Earl Levine, Owner: Peter Korsgaard
• buildroot.net
  • Owner: Peter Korsgaard

• DNS for both handled through http://gratisdns.dk

Web site

• Source in the main Buildroot Git repository, in docs/website/
• Automatically pulled on the server by ???
• Hosted by osuosl.org, VM shared with busybox/uclibc

Autobuilder

• http://autobuild.buildroot.org points to a machine hosted by User:ThomasPetazzoni, a dedicated server he is renting
• This infrastructure tests random configurations
• The site runs the code at https://git.buildroot.net/buildroot-test, in the web/ subdirectory. It is made of very ugly PHP code, backed by a MySQL database.
• The autobuild.buildroot.org machine doesn't do any builds itself, it only collects build results that are HTTP POSTed by other machines, called build slaves
• The build slaves run the Python script at https://git.buildroot.net/buildroot-test/tree/scripts/autobuild-run
• Currently used build slaves:
  • Free Electrons build server, managed by ThomasPetazzoni
  • gcc10, gcc20 from the GCC compile farm, managed by Peter Korsgaard
  • ...
• People having account to HTTP POST build results:
  • tpetazzoni
  • pkorsgaard
  • rbraun
  • nroach
  • mweber
  • mhadjinlian
  • jboibessot
  • vriera
  • gustavo
  • ymorin
  • ahentschel

Mailing list

• https://buildroot.org/lists/buildroot/
• Mailman server, maintained by osuosl.org

Bug tracker

• https://bugs.buildroot.net/
• Bugzilla, hosted on buildroot/busybox/uclibc VM (osuosl.org)
• Maintained by Mike Frysinger
• Instance shared with busybox/uclibc

Git repository

• The main Git repository is at https://git.buildroot.net/buildroot, hosted by osuosl.org
  • E-mail notification messages are sent to the mailing list using /git/hooks/send-email hosted by osuosl.org
  • IRC notification messages are posted using irkerbot (/git/hooks/post-receive) hosted by osuosl.org
• A secondary Git repository is on Github at https://github.com/buildroot/buildroot
  • Mainly to have an official Github mirror, rather than only unofficial forks of Buildroot
  • Kept in sync with the main Git repository by a cronjob run every 10 minutes on ThomasPetazzoni dedicated server.
• Another mirror on Gitlab at https://gitlab.com/buildroot.org/buildroot - details below

Gitlab project

• Gitlab group buildroot.org, with project https://gitlab.com/buildroot.org/buildroot
  • Administrators are Peter, Thomas and Arnout
• Main purpose is to run automatic tests
  • controlled by .gitlab-ci.yml in the repository itself
  • https://gitlab.com/buildroot.org/buildroot/pipelines
  • triggered on every push to the repository
  • mail is sent to mailing list when pipeline fails
  • for convenience, CI runs in a custom docker image, https://hub.docker.com/r/buildroot/base/
    • generated from support/docker/Dockerfile
    • not generated automatically, since this can't be done from Gitlab-CI itself
• Repository is synced from git.buildroot.org
  • In principle once per day, but sometimes pull fails
  • Better approach: push to the repo from a cron job - TBD
• Irker and commit emails could be run from here as well, but currently aren't.

Sources.buildroot.net

• Mirror of (nearly?) all Buildroot tarballs/patches.
• Runs on a dedicated VM hosted by osuosl.org
• Cronjob updating mirror every 2 hours doing make randconfig +

 make -k BR2_BACKUP_SITE= $(find -name \*.mk|sed 's|.*/\([^/]*\)\.mk|\1-source host-\1-source|')

• Also generates nightly documentation for nightly.buildroot.net every 6 hours:

 make manual-html manual-pdf manual-text

Patchwork

• Available at http://patchwork.ozlabs.org/project/buildroot/ or the alias http://patchwork.buildroot.net (HTTP redirect running on sources.buildroot.net)
• Hosted by Jeremy Kerr, from Ozlabs. He is the point of contact in case of patchwork issues.
