# NOTE:
# Disk cache:
# We don't want to keep old artifacts around so we always build from
# scratch on master builds and upload the new cache afterwards. Because
# Circle doesn't allow skipping a "restore_cache" we create a dummy
# "empty" cache that's only ever pulled on master. Alternatively we could
# ask Bazel to clean up old items (LRU style) but the documentation is
# very terse and I could not figure how to do it:
# https://docs.bazel.build/versions/master/remote-caching.html
# It also appears that there's ongoing work but the feature is not ready:
# https://github.com/bazelbuild/bazel/issues/5139
#
# Currently the disk cache is only implemented for the Darwin builds,
# which were the slowest ones. There is no reason why a disk cache
# couldn't be used for the other jobs: I just haven't gotten around to
# doing it.
