# Cleanup
############################################################

# Note [Cleaning up after shell executor]
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#
# As noted in [1], gitlab-runner's shell executor doesn't clean up its working
# directory after builds. Unfortunately, we are forced to use the shell executor
# on Darwin. To avoid running out of disk space we add a stage at the end of
# the build to remove the /.../GitLabRunner/builds directory. Since we only run a
# single build at a time on Darwin this should be safe.
#
# We used to have a similar cleanup job on Windows as well however it ended up
# being quite fragile as we have multiple Windows builders yet there is no
# guarantee that the cleanup job is run on the same machine as the build itself
# was run. Consequently we were forced to instead handle cleanup with a separate
# cleanup cron job on Windows.
