# Force a repair special task for any host that hasn't seen activity in
# the past day.
#
# Various scripts/cron jobs look for DUTs that aren't working.  To be
# conservative, those scripts assume that a DUT that hasn't run any jobs
# within a reasonable time interval isn't working, since some of the
# ways a DUT may be unavailable manifest as inactivity.
#
# In some cases, we'd like to be more certain as to a DUT's status.
# This script goes through the entire AFE hosts table, and identifies
# unlocked hosts that would otherwise be flagged as "not working due to
# lack of activity", and forces a repair task.
#
# We use a repair task (as opposed to verify) for various reasons:
#   + If a DUT is working, repair and verify perform the same checks,
#     and generally run in the same time.
#   + If a DUT is broken, a verify task will fail and invoke repair,
#     which will take longer than just repair alone.
#   + Repair tasks that pass update labels; without this, labels could
#     become out-of-date simply because a DUT is idle.
#
# Locked hosts are skipped because they can't run jobs and because we
# want them to show up as suspicious anyway.
