# Ideally this would be done in seperate workflows but placing them all
# in one is currently necessary to enforce job dependencies
#######################################

#######################################
# Note the use of multiple checkout actions in most jobs.  This has been
# implemented to allow the use of CI scripts at a different ref or sha than
# the source code they're evaluating.  For push events (when a pull_request is
# merged) there is no difference.  However, for pull_request events this allows
# us test code at the head of a pull_request using the CI scripts from the
# prospectively merged pull_request, which will include any CI updates that
# may have made it to the target branch after the pull_request was started.
#######################################

#######################################
# Note regarding restore/save of cache for use by ccache:
#
# We only save cache on main branch runs. PR workflows only consume the
# cache to avoid exceeding the 10 GB limit, which can cause cache thrashing.
# Also, we only save the cache if there was *not* an exact match when cache
# was restored. This avoids attempting to write to an existing cache key,
# which results in failure to save the cache. While failure to save doesn't
# cause job failures, it seems a waste and is easily avoidable.
