Try the build slave locally

This overlaps with the buildd part of HowToUseSoyuzLocally, but shows you how to set up the buildd in a chroot without customizing your own system setup for it.

Build the package

  cd lib/canonical/buildd
  debian/rules package
  dpkg-buildpackage -b

Package is lib/canonical/launchpad-buildd*all.deb

Set up pbuilder chroot

To avoid installing the launchpad-buildd package on my computer, I use pbuilder to create an manage a chroot environment.

Make sure you have pbuilder installed:

sudo apt-get install pbuilder

If archive.ubuntu.com is too far away from you network-wise, you can configure MIRRORSITE in /etc/pbuildderrc to use a mirror that's faster for you. Then do

  sudo pbuilder --create --distribution lucid
  sudo pbuilder --login --save-after-login

Now you should find yourself inside the chroot. To satisfy the NTP needs of the launchpad-buildd, define it to be the IP of ntp.ubuntu.com or whatever NTP server you like.

  echo "91.189.94.4  ntp.buildd" >> /etc/hosts
  exit

After exit, the chroot will be re-packaged by pbuilder to save the changes. You might choose to save other steps as well but usually I configure the chroot whenever I run it, like so.

  sudo pbuilder --login --inputfile lib/canonical/launchpad-buildd_*_all.deb

Inside the chroot again: Install and start buildd:

  dpkg --force-depends -i /tmp/buildd/launchpad-buildd*all.deb
  apt-get -f install
  /etc/init.d/launchpad-buildd start

We need a package to try out the generation of translation templates. Eventually this will be pulled in via bazaar but now I do it manually. Obviously, this is specific to this type of build. Inside the chroot edit /etc/apt/sources.list to enable the deb-src line. Then pull in a source pacakge. Gimp has a couple of translation templates.

  apt-get update
  cd /home/buildd
  su buildd
  apt-get source gimp

Upload chroot to librarian

Outside the chroot, in another terminal (leave the buildd in the chroot running!) Get the builder chroot from https://edge.launchpad.net/api/devel/ubuntu/lucid/i386/chroot_url.

wget -O - -q https://edge.launchpad.net/api/devel/ubuntu/lucid/i386/chroot_url | xargs wget

This should give you a file chroot-ubuntu-lucid-i386.tar.bz2. This is the chroot tarball for Lucid on i386.

Upload it to the Librarian, but while you're at it, also register it as the chroot for Lucid:

  make run & # (Need Librarian running, and make start_librarian didn't work)
  scripts/upload2librarian -f chroot-ubuntu-lucid-i386.tar.bz2
  --> http://launchpad.dev:58080/93/chroot-ubuntu-lucid-i386.tar.bz2

Copy that URL you got from upload2librarian for the next step.

Drive slave through rpc

With the libranrian still running, fire up a python shell and:

import xmlrpclib
proxy = xmlrpclib.ServerProxy('http://localhost:8221/rpc')
proxy.ensurepresent('f1f10b8402ed686aaf0307676c76f07b45af2a09', 'http://launchpad.dev:58080/93/chroot-ubuntu-lucid-i386.tar.bz2', '', '')
proxy.build('1-1', 'translation-templates', 'f1f10b8402ed686aaf0307676c76f07b45af2a09', {},
  {'archives': 'deb http://archive.ubuntu.com/ubuntu/ lucid main', 'branch_url': '/home/buildd/gimp-2.6.8'})
proxy.status()
proxy.clean() # Clean up if it failed

Inspect buildlog

Inside the chroot:

  less /home/bulidd/filecache-default/buildlog
