# We use two different caching strategies. The default is to cache pip
# packages (as most of our jobs use pip packages), which is configured here.
# For the integration tests, we instead want to cache the lxd images and
# package build schroot.
#
# We cache the lxd images because this saves a few seconds in the general
# case, but provides substantial speed-ups when cloud-images.ubuntu.com, the
# source of the images, is under heavy load. The directory in which the lxd
# images are stored (/var/snap/lxd/common/lxd/images/) is not
# readable/writeable by the default user (which is a requirement for caching),
# so we instead cache the `lxd_images/` directory. We move lxd images out of
# there before we run tests and back in once tests are complete. We _move_ the
# images out and only copy the most recent lxd image back into the cache, to
# avoid our cache growing without bound. (We only need the most recent lxd
# image because the integration tests only use a single image.)
#
# We cache the package build schroot because it saves 2-3 minutes per build.
# Without caching, we have to perform a debootstrap for every build. We update
# the schroot before storing it back in the cache, to ensure that we aren't
# just using an increasingly-old schroot as time passes. The cached schroot is
# stored as a tarball, to preserve permissions/ownership.
