# The logic for each $FARM is as follows:
#
# If the disable file exists, we are disabling the farm, or it's already
# disabled:
#   - exists: [ .ci-farms-disabled/$FARM ]
#     when: never
#
# Otherwise, changing the disable file means removing it, so we are
# re-enabling the farm:
#   - changes: [ .ci-farms-disabled/$FARM ]
#     if: '$CI_PIPELINE_SOURCE != "schedule"'
#     when: on_success
# Note: the "manual" variant of each farm rules changes the above to `never`,
# so that jobs meant to be manual don't run in re-enablement MRs. This is the
# only difference between `.$FARM-farm-rules` and `.$FARM-farm-manual-rules`.
#
# If any other disable file is modified, we are disabling/re-enabling another
# farm:
#   - changes: [ .ci-farms-disabled/* ]
#     if: '$CI_PIPELINE_SOURCE != "schedule"'
#     when: never
#
# The `not schedule` condition is there to make sure scheduled pipelines
# contains all the jobs, as `changes` conditions in scheduled pipelines are
# always evaluated to `true`.
#
# The "fallback", if none of these rules match, is usually the list of files
# that are used by a driver. See the various `.$DRIVER-rules` in the
# corresponding `src/**/ci/gitlab-ci.yml`.
