Setting up a local Soyuz

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.

After this, your sample data will include a realistic sampling of Ubuntu releases, and you'll have a user called "ppa-user" with password "test" and using your own email address. You'll be able to log in with your own email address, and sign things for this user with your own GPG key. The user is an Ubuntero and a member of ubuntu-team.

Configure an account and PPA

Set up the PPA

You'll find a pre-made PPA for ppa-user. It has an external dependency on Lucid. If that's not enough, or not what you want:

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

Configure a buildd

  • cd lib/canonical/buildd

  • debian/rules package

  • dpkg-buildpackage -b

  • sudo dpkg -i ../launchpad-buildd_50_all.deb

  • sudo apt-get -f install

  • Make it work.
    • Might need to add --umask=022 to twistd args in /etc/init.d/launchpad-buildd, or pkg-create-dbgsym fails obscurely.

    • 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.

  • Get an Ubuntu buildd chroot from Launchpad

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

Please note a "builder" and a "chroot" are not the same thing, nor are they "associated" in any way. The logic is as follows:

  • PPAs require builders (a machine where to build packages)
  • The builder may be virtualized (for instance, launchpad.net uses Xen-virtualized builders) or the same machine where Launchpad (meaning "your launchpad.dev") is running, which is what this page details. Using the very same machine where Launchpad.dev is running limits the architectures you can build for: if you are running on i386, you can't build for PowerPC, for instace.
  • A builder needs to setup a bootstrap (what you get with debootstrap) Linux. That bootstrap is what you get in the chroot tarballs mentioned above.
  • When you upload a package and tell Launchpad to process it (see below for this), the builder will pick the chroot it needs (for instance, karmic i386), uncompress it and start building the package.
  • In summary, there are two lists: a list of builders and a list of chroots.

Upload a source to the PPA

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

Dealing with the primary archive

Notes

Amd64 chroots

Run the query below (e.g. using "psql -d launchpad_dev") before running make-ubuntu-sane.py in case you want to be able to set up amd64 chroots for build slaves. (Moving into script per bug 527170 —jtv)

INSERT INTO distroarchseries (distroseries, processorfamily, architecturetag, owner, official) VALUES (3, 3, 'amd64', 1, true);

It adds an amd64 DistroArchSeries for hoary from which all the subsequent distro series are cloned by the make-ubuntu-sane.py script.

MTA needed

You need to have some sort of MTA (e.g. postfix) running in order for the email to be placed in the root's mailbox. In cases where you have Launchpad running in a chroot you'll need to stop the "normal" MTA and start it in the chroot or configure the one in the chroot to use a different port.

Gpg CRC errors

Run gpg like this "gpg --ignore-crc-error -d <file>" in case you see the following error message while decrypting the email sent by launchpad:

gpg: malformed CRC
gpg: quoted printable character in armor - probably a buggy MTA has been used

Errors importing key to local zeca

If you are getting an error when importing your key to zeca and you are running Lucid, and bug 452194 is not fixed, you will need to:

  1. Grab the one line patch.,

  2. Apply it (patch -p0 sourcecode/pygpgme/src/pygpgme-context.c < pygpgme.patch)

  3. make compile and then restart your local development zeca as well as the web app.
