https://gitlab.com/libvirt/libvirt-ci
In that project, there is a ``mappings.yml`` file defining the distro native
package names for a wide variety of third party projects. This is processed
in combination with a project defined list of build pre-requisites to determine
the list of native packages to install on each distribution. This can be used
to generate dockerfiles, VM package lists and Cirrus CI variables needed to
setup build environments across OS distributions with a consistent set of
packages present.
When preparing a patch series that adds a new build pre-requisite to QEMU,
updates to various lcitool data files may be required.
``libvirt-ci`` contains an ``lcitool`` program as well as a list of
mappings to distribution package names for a wide variety of third
party projects. ``lcitool`` applies the mappings to a list of build
pre-requisites in ``tests/lcitool/projects/qemu.yml``, determines the
list of native packages to install on each distribution, and uses them
to generate build environments (dockerfiles and Cirrus CI variable files)
that are consistent across OS distribution.
Adding new build pre-requisites
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
When preparing a patch series that adds a new build
pre-requisite to QEMU, the prerequisites should to be added to
``tests/lcitool/projects/qemu.yml`` in order to make the dependency
available in the CI build environments.
In the simple case where the pre-requisite is already known to ``libvirt-ci``
the following steps are needed
the following steps are needed:
* Edit ``tests/lcitool/projects/qemu.yml`` and add the pre-requisite
* Run ``make lcitool-refresh`` to re-generate all relevant build environment
manifests
In some cases ``libvirt-ci`` will not know about the build pre-requisite and
thus some extra preparation steps will be required first
It may be that ``libvirt-ci`` does not know about the new pre-requisite.
If that is the case, some extra preparation steps will be required
first to contribute the mapping to the ``libvirt-ci`` project:
* Fork the ``libvirt-ci`` project on gitlab
* Edit the ``mappings.yml`` change to add an entry for the new build
prerequisite, listing its native package name on as many OS distros
as practical.
* Add an entry for the new build prerequisite to
``lcitool/facts/mappings.yml``, listing its native package name on as
many OS distros as practical. Run ``python -m pytest --regenerate-output``
and check that the changes are correct.
* Commit the ``mappings.yml`` change and submit a merge request to
the ``libvirt-ci`` project, noting in the description that this
is a new build pre-requisite desired for use with QEMU
* Commit the ``mappings.yml`` change together with the regenerated test
files, and submit a merge request to the ``libvirt-ci`` project.
Please note in the description that this is a new build pre-requisite
desired for use with QEMU.
* CI pipeline will run to validate that the changes to ``mappings.yml``
are correct, by attempting to install the newly listed package on
all OS distributions supported by ``libvirt-ci``.
* Once the merge request is accepted, go back to QEMU and update
the ``libvirt-ci`` submodule to point to a commit that contains
the ``mappings.yml`` update.
the ``tests/lcitool/libvirt-ci`` submodule to point to a commit that
contains the ``mappings.yml`` update. Then add the prerequisite and
run ``make lcitool-refresh``.
For enterprise distros that default to old, end-of-life versions of the
Python runtime, QEMU uses a separate set of mappings that work with more
recent versions. These can be found in ``tests/lcitool/mappings.yml``.
Modifying this file should not be necessary unless the new pre-requisite
is a Python library or tool.
Adding new OS distros
