# This file uses the freedesktop ci-templates to build Weston and run our
# tests in CI.
#
# ci-templates uses a multi-stage build process. First, the base container
# image is built which contains the core distribution, the toolchain, and
# all our build dependencies. This container is aggressively cached; if a
# container image matching $FDO_DISTRIBUTION_TAG is found in either the
# upstream repo (wayland/weston) or the user's downstream repo, it is
# reused for the build. This gives us predictability of build and far
# quicker runtimes, however it means that any changes to the base container
# must also change $FDO_DISTRIBUTION_TAG. When changing this, please use
# the current date as well as a unique build identifier.
#
# After the container is either rebuilt (tag mismatch) or reused (tag
# previously used), the build stage executes within this container.
#
# The final stage is used to expose documentation and coverage information,
# including publishing documentation to the public site when built on the
# main branch.
#
# Apart from the 'variables', 'include', and 'stages' top-level anchors,
# everything not beginning with a dot ('.') is the name of a job which will
# be executed as part of CI, unless the rules specify that it should not be
# run.
#
# Variables prefixed with CI_ are generally provided by GitLab itself;
# variables prefixed with FDO_ and templates prefixed by .fdo are provided
# by the ci-templates.
#
# For more information on GitLab CI, including the YAML syntax, see:
#   https://docs.gitlab.com/ee/ci/yaml/README.html
#
# Note that freedesktop.org uses the 'Community Edition' of GitLab, so features
# marked as 'premium' or 'ultimate' are not available to us.
#
# For more information on ci-templates, see:
