You're going to run Soyuz in a branch you create for the purpose. To get the whole experience, you'll also be installing the slave-side launchpad-buildd package on your system.

Initial setup

• Run utilities/start-dev-soyuz.sh to ensure that some Soyuz-related services are running. Some of these may already be running, in which case you'll get some failures that are probably harmless. Note: these services eat lots of memory.

• Once you've set up your test database, run utilities/soyuz-sampledata-setup.py -e you@example.com (where you@example.com should be an email address you own and have a GPG key for). This prepares more suitable sample data in the launchpad_dev database, including recent Ubuntu series. If you get a "duplicate key" error, make schema and run again.

• make run (or if you also want to use codehosting, make run_codehosting—some services may fail to start up because you already started them, but it shouldn't be a problem).

• Open https://launchpad.dev/~ppa-user/+archive/test-ppa in a browser to get to your pre-made testing PPA. Log in with your own email adddress and password test. This user has your GPG key associated, has signed the Ubuntu Code of Conduct, and is a member ubuntu-team (conferring upload rights to the primary archive).

Extra PPA dependencies

The testing PPA has an external dependency on Lucid. If that's not enough, or not what you want:

• Log in as admin@canonical.com:test (I suggest using a different browser so you don't break up your ongoing session).

• Open https://launchpad.dev/~ppa-user/+archive/test-ppa/+admin

• Edit external dependencies. They normally look like:

deb http://archive.ubuntu.com/ubuntu %(series)s main restricted universe multiverse

Setup a build slave

Installation

• Create a new trusty virtual-machine with kvm (recommended), or alternatively a trusty lxc container. If using lxc, set lxc.aa_profile = unconfined in /var/lib/lxc/container-name/config which is required to disable AppArmor support. If you are running Launchpad in a container, you will more than likely want your VM's network bridged on lxcbr0.

In your slave vm/lxc:

• sudo apt-add-repository ppa:launchpad
• sudo apt-get update
• sudo apt-get install launchpad-buildd

• Edit /etc/launchpad-buildd/default and make sure ntphost points to an existing NTP server. You can check the NTP server pool to find one near you.

Launchpad Configuration

• cd lib/canonical/buildd

• debian/rules package

• dpkg-buildpackage -b

• sudo dpkg -i ../launchpad-buildd_*_all.deb

• sudo apt-get -f install

From your host system:

• Get an Ubuntu buildd chroot from Launchpad, using manage-chroot from lp:ubuntu-archive-tools:

manage-chroot -s precise -a i386 get
LP_DISABLE_SSL_CERTIFICATE_VALIDATION=1 manage-chroot -l dev -s precise -a i386 -f chroot-ubuntu-precise-i386.tar.bz2 set

• Mark Bob the Builder as OK (https://launchpad.dev/builders/bob/+edit)

Drive slave through rpc

With librarian running, fire up a python shell and:

import xmlrpclib
proxy = xmlrpclib.ServerProxy('http://localhost:8221/rpc')
proxy.ensurepresent('d267a7b39544795f0e98d00c3cf7862045311464', 'http://launchpad.dev:58080/93/chroot-ubuntu-lucid-i386.tar.bz2', '', '')
proxy.build('1-1', 'translation-templates', 'd267a7b39544795f0e98d00c3cf7862045311464', {},
  {'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

You may have to calculate a new sha1sum of the chroot file.

Upload a source to the PPA

• Run scripts/process-upload.py /var/tmp/txpkgupload (creates hierarchy)

• Add to ~/.dput.cf:

[lpdev]
fqdn = ppa.launchpad.dev:2121
method = ftp
incoming = %(lpdev)s
login = anonymous

• Find a source package some_source with a changes file some_source.changes

• dput -u lpdev:~ppa-user/test-ppa/ubuntu some_source.changes

• scripts/process-upload.py /var/tmp/txpkgupload -C absolutely-anything -vvv # Accept the source upload.

• If this is your first time running soyuz locally, you'll also need to publish ubuntu: scripts/publish-distro.py -C

• Within five seconds of upload acceptance, the buildd should start building. Wait until it is complete (the build page will say "Uploading build").

• scripts/process-upload.py -vvv --builds -C buildd /var/tmp/builddmaster # Process the build upload.

• scripts/process-accepted.py -vv --ppa ubuntu # Create publishings for the binaries.

• scripts/publish-distro.py -vv --ppa # Publish the source and binaries.

  • Note that private archive builds will not be dispatched until their source is published.

Dealing with the primary archive

• dput lpdev:ubuntu some_source.changes

• scripts/process-upload.py -vvv /var/tmp/txpkgupload

• Watch the output -- the upload might end up in NEW.
  • If it does, go to the queue and accept it.
• Your builder should now be busy. Once it finishes, the binaries might go into NEW. Accept them if required.

• scripts/process-accepted.py -vv ubuntu

• scripts/publish-distro.py -vv

  • The first time, add -C to ensure a full publication of the archive.
