Managing the Bazaar PPA ======================= See also: `Bazaar Developer Document Catalog `_. Background ---------- We build Ubuntu ``.deb`` packages for Bazaar as an important part of the release process. These packages are hosted in a few `Personal Package Archives (PPA)`__ on Launchpad. __ https://help.launchpad.net/PPAQuickStart As of June 2010, there are three PPAs: Final released versions and updates. Proposed uploads to move into ~bzr, awaiting testing. Beta releases. Automatic nightly builds from trunk. We build a distinct package for each distrorelease. If you upload a release-specific version, you should add a suffix to the package version, e.g. ``bzr.1.3-1~bazaar1~dapper1``. Dapper uses the ``python-support`` framework and later distributions use ``python-central``. This has little effect on everyday packaging but does mean that some of the control files are quite different. Every package is first uploaded into the beta ppa. For final release versions it is also copied to the main PPA. The packaging information is kept in branches of bzr on Launchpad, named like . or . These branches are intended to be used with the ``bzr-builddeb`` plugin. **You should almost always upload to the beta ppa first** and then either upload again or copy the packages into the release ppa. That reduces the risk of breaking the main archive from which people get bzr updates. Supported releases ------------------ We build packages for every supported Ubuntu release . Packages need no longer be updated when the release passes end-of-life because all users should have upgraded by then. As of August 2010, the following releases are supported: * Maverick * Lucid LTS * Karmic * Jaunty (support ends October 2010) * Hardy LTS * Dapper LTS (supported but no longer updated for new releases) Preconditions ------------- * You must have a Launchpad account and be a member of the teams that own these PPAs (``~bzr``, ``~bzr-beta-ppa``). * You must have a GPG key registered to your Launchpad account. On reasonably recent versions of Ubuntu you no longer need special dput configuration, because you can just say :: dput ppa:bzr/proposed to wrap it. Update all packages in proposed before copping the main ppa ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If one updates bzr, and there are plugins that are not compatible with the new version of bzr, this can cause pain for users using the ppa. In order to avoid this, we first get all packages up to date in the proposed ppa, and then copy them to the main ppa. Short form ~~~~~~~~~~ For people who have already set up everything they need, building the release packages is as simple as:: cd ~/dev/bzr/releases/packaging export VERSION="1.17~rc1-1~bazaar1" export PACKAGE="bzr" export UBUNTU_RELEASES="dapper hardy intrepid jaunty karmic" ~/dev/bzr/bzr.dev/tools/packaging/update-packaging-branches.sh * Optionaly merge debian unstable. ~/dev/bzr/bzr.dev/tools/packaging/update-changelogs.sh ~/dev/bzr/bzr.dev/tools/packaging/update-control.sh 1.16 1.17 1.18 ~/dev/bzr/bzr.dev/tools/packaging/build-packages.sh dput ppa:bzr/proposed ${PACKAGE}_$VERSION*.changes Rinse and repeat for all the plugins by changing VERSION and PACKAGE. Long Form ~~~~~~~~~ #. You will end up checking out a separate directory for each supported release. Such as ``~/dev/bzr/releases/packaging/hardy``. In each of these branches, you will produce the package for the release. The scripts will also create the branches and produce packages for bzrtools and bzr-svn. #. Decide on the final version number. It should be of this form:: bzr-1.17~rc1-1~bazaar1~hardy1 **Note:** There are three hyphen-separated parts: the *package name*, the *upstream version*, and the *packaging version*. **Caution:** Upstream betas or release candidates must insert a tilde to make them sort before the final release, like this: ``bzr-1.17~rc1-1~bazaar1~hardy1``. Final releases will use a release string of the form: ``bzr-1.17-1~bazaar1~hardy1`` Set this base of this up as a usable environment variable:: export VERSION="1.17~rc1-1~bazaar1" #. Export the distroreleases that you will be packaging for:: export UBUNTU_RELEASES="dapper hardy intrepid jaunty karmic" #. Export the program you are packaging:: export PACKAGE="bzr" #. Checkout (or update) the packaging branch for each supported release:: bzr co lp:~bzr/ubuntu/hardy/bzr/bzr-ppa There is a script available to help:: tools/packaging/update-packaging-branches.sh #. Optionaly, merge the Debian unstable branch into each of the packaging branches. You can find the Debian unstable branch here: http://bzr.debian.org/pkg-bazaar/ #. The ``bzr-builddeb`` step will download the original tarball if you do not already have it, putting it into a ``tarballs`` directory. #. For Bazaar plugins, change the ``debian/control`` file to express a dependency on the correct version of ``bzr``. For bzrtools this is typically:: Build-Depends-Indep: bzr (>= 1.17~), rsync Depends: ${python:Depends}, bzr (>= 1.17~), bzr (<< 1.18~), patch There is a helper script which will update the control file and commit it for all of your ``$UBUNTU_RELEASES``. It is available as:: tools/packaging/update-control.sh You must supply the versions as arguments as follows OLD_VERSION CURRENT_VERSION NEXT_VERSION, such as:: tools/packaging/update-control.sh 1.16 1.17 1.18 #. Make a new ``debian/changelog`` entry for the new release, either by using ``dch`` or just editing the file:: dch -v '1.17~rc1-1~bazaar1~hardy1' -D hardy dch will default to the distro you're working in and this isn't checked against the version number (which is just our convention), so make sure to specify it. Make sure you have the correct email address for yourself (you may need export DEBEMAIL=`bzr whoami` if it isn't already set), version number, and distribution. It should look something like this:: bzr (1.17~rc1-1~bazaar1~hardy1) hardy; urgency=low * New upstream release. -- John Sample Mon, 31 Mar 2008 12:36:27 +1100 If you need to upload the package again to fix a problem, normally you should increment the last number in the version number, following the distro name. Make sure not to omit the initial ``-1``, and make sure that the distro name in the version is consistent with the target name outside the parenthesis. You will also want to commit these changes into the packaging branch. There is a helper script which will build all the packages for all of your ``$UBUNTU_RELEASES``. It is available as:: tools/packaging/update-changelogs.sh #. Build the source packages:: cd bzr-$DISTRO; bzr builddeb -S This will create a ``.changes`` file. If you didn't configure builddeb to automatically sign them, you can use :: debsign -m$UID *.changes where ``$UID`` is the gpg key you want to use to sign the changes. There is a helper script which will build the package for all of your ``$UBUNTU_RELEASES``. It is available as:: tools/packaging/build-packages.sh #. Upload into the PPA for each release:: dput dput ppa:bzr/proposed bzr*1.17-1*.changes #. You should soon get an "upload accepted" mail from Launchpad, which means that your package is waiting to be built. You can then track its progress in and . Packaging bzr-svn ~~~~~~~~~~~~~~~~~ bzr-svn uses a packaging branch that contains both the source (including any changes against upstream) and the ``debian/`` directory. To build bzr-svn: #. Get a checkout of ``lp:~bzr/bzr-svn/hardy-ppa/`` #. Merge from ``http://bzr.debian.org/pkg-bazaar/bzr-svn/unstable/`` This should bring in both upstream and packaging changes for the new release, and it's updated as part of the bzr-svn release process. It's quite possible you will need to resolve some conflicts. #. Run ``dch -v 0.4.15-1~bazaar1-hardy1 -D hardy`` or similar #. Run ``bzr builddeb --source`` bzr-builddeb will automatically check out the appropriate tag from the main branch of bzr-svn, build, and package it. #. ``dput bzr-beta-ppa ../bzr-svn_0.4.15-1~bazaar1~hardy1_source.changes`` Monitoring the contents of PPAs ------------------------------- If you add all the bzr PPAs to your ``sources.list`` then you can see a summary of current package versions with:: apt-cache madison bzr Packaging dependencies ---------------------- Some of our updates to bzr in previous releases require backports of our dependencies. Specific branches holding these backports: * ``lp:~bzr/ubuntu/dapper/configobj/dapper-backport`` .. vim: filetype=rst textwidth=74 ai shiftwidth=4
