= Try the build slave locally =

'''This overlaps in part with [[Soyuz/HowToUseSoyuzLocally|HowToUseSoyuzLocally]] which I found out about too late.'''

== 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. Like me, you can configure MIRRORSITE in /etc/pbuildderrc to use a closer mirror, if you want. 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 launcahpd-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 -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. We need a running librarian now.

{{{
  make run (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 for the next step.

== Drive slave through rpc ==

With the libranrian still running, fire up a python shell.

{{{
  python
  >>> 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', {}, {'branch_url': '/home/buildd/gimp-2.4.5'})
  >>> proxy.status()
  >>> proxy.clean() # Clean up if it failed
}}}

== Inspect buildlog ==

Inside the chroot:
{{{
  less /home/bulidd/.../buildlog
}}}
