OpenStack Core Packages - How to update, build, and contribute
Ubuntu maintains its own set of Git repositories on Launchpad.
The following tasks require a basic knowledge of Ubuntu packaging. For an introduction, see the Ubuntu Packaging Guide.
First, you'll want to setup git to simplify your work-flow. See 'Configuring Git' in the Launchpad git documentation.
The OpenStack packaging git repositories all make use of git-buildpackage and pristine-tar for managing upstream release tarballs.
For a general overview of git-buildpackage and pristine-tar, see the Debian documentation. This wiki page details the specifics of how we use these tools in Ubuntu.
The current development release packaging is maintained under the 'master' branch; released versions of OpenStack will mirror upstream branch management - e.g. stable/queens.
Cloning a git repository
If you are running on the latests Ubuntu release, then the following should dtrt:
debcheckout --git-track='*' <projectname>
debcheckout --git-track='*' nova
Using the git-track option ensures that all required branches are automatically setup - for example:
$ git branch * master pristine-tar upstream
The 'upstream' and 'pristine-tar' branches are used by git-buildpackage to manage the upstream release tarballs.
If you're not on the latest Ubuntu release then directly clone the repository and checkout the branches:
git clone lp:~ubuntu-openstack-dev/ubuntu/+source/nova git checkout pristine-tar git checkout upstream git checkout master
Alternatively, if you haven't configured git to work with Launchpad (see 'Git Configuration' above), you can clone with:
git clone https://git.launchpad.net/~ubuntu-openstack-dev/ubuntu/+source/nova
Building a source package
For all packages, use the buildpackage subcommand of gbp:
gbp buildpackage -S
To build without signing the .changes/.dsc files:
gbp buildpackage -S -us -uc
The source package will be placed in ../build-area.
Note that for horizon and heat-dashboard, we bundle the xstatic code alongside the upstream release tarball, so they have 2 orig tarballs. git-buildpackage supports multiple orig tarballs now.
To generate a new xstatic orig tarball (see horizon/debian/README.source):
Re-generating xstatic files for stable releases can be problematic. The general recommendation is to download the existing xstatic orig tarball from Launchpad and rename it accordingly.
Building Debian packages
We generally use sbuild to build debian packages.
Steps for building an OpenStack Queens package for bionic:
mk-sbuild bionic sbuild-update -udc bionic-amd64 sbuild -A -d bionic-amd64 <path-to-dsc-file>
For initial setup steps see: https://wiki.ubuntu.com/SimpleSbuild
Steps for building an OpenStack Queens package for xenial:
sudo add-apt-repository ppa:ubuntu-cloud-archive/tools sudo apt update sudo apt install cloud-archive-utils mk-sbuild xenial sbuild-update -udc xenial-amd64 sbuild-queens -A -d xenial-amd64 <path-to-dsc-file>
Making a packaging change
Each independent change should be committed separately to the git repository, and each change should include a short description of the change in debian/changelog. To make your initial update to debian/changelog:
After the initial update you can edit the changelog with your favorite editor.
Make your packaging changes as you normally would under the debian folder; then use 'git add' to add the changed files to the staging area; if you have added an appropriate changelog comment then:
will DTRT and annotate the git commit with the changelog entry details - you get a chance to edit this if you have provided anything other than a single line entry to the changelog.
Updating to a new release
First, grab the new upstream release:
uscan --verbose --rename (and optionally: --download-version <version>)
this will drop the orig.tar.gz into the parent folder of the git repository. Then use git-buildpackage to import the archive:
gbp import-orig ../nova_12.0.0~b1.orig.tar.gz
This action will import the content into the upstream branch, create the required pristine-tar data and place it in the pristine-tar branch, and then merge the upstream branch into the master branch (or stable branch).
Maintainers - release a package and push updates to Launchpad
Change the Ubuntu release in d/changelog from UNRELEASED to the corresponding Ubuntu release name and:
git commit -m "releasing package $package version $version-$ubuntu_vers" debian/changelog
Then tag the release:
git tag -s debian/$version -m "tagging package $package version debian/$version"
Then push any local commits and tags to Launchpad:
git push --all git push --tags
NOTE: you need to be a member of the ubuntu-openstack-dev team to be able todo this - this includes all Ubuntu Core Developers.
Contributors - pushing a personal repository to Launchpad
To push any local commits and tags to Launchpad:
git push --all lp:~<launchpad-id>/ubuntu/+source/nova git push --tags lp:~<launchpad-id>/ubuntu/+source/nova
Contributors - proposing a change
There are a few ways to propose a package change:
1. Reference your git repo in the bug report:
2. Attach a debdiff to the bug report:
debdiff nova_current_version.dsc nova_new_version.dsc > nova_new_version.debdiff
3. Create a launchpad merge proposal:
Navigate to the URL of your pushed repository: https://code.launchpad.net/~<launchpad-id>/ubuntu/+source/nova/+git/nova
Propose each branch separately:
- Click on the branch name and 'Propose for merging'
- Select the target repository: lp:~ubuntu-openstack-dev/ubuntu/+source/nova
- Select the target reference path: master, upstream, or pristine-tar
