# Raising a blank exception is done here because any message we can
# give here would be less useful than whatever the failing test left as
# its own exception message.
# The gory details of how raising a blank exception accomplishes this
# is as follows:
# The scheduler only looks at the return code of autoserv to see if
# the special task failed. Therefore we need python to exit because
# of an unhandled exception or because someone called sys.exit(1).
# We can't call sys.exit, since there's post-job-running logic (like
# cleanup) that we'd be skipping out on. So therefore, we need to
# raise an exception. However, if we raise an exception, this
# exception ends up triggering server_job to write an INFO line with
# job_abort_reason equal to str(e), which the tko parser then picks
# up as the reason field for the job when the status.log we generate is
# parsed as the job's results.
# So therefore, we raise a blank exception, which then generates an
# empty job_abort_reason which the tko parser ignores just inserts as
# a SERVER_JOB failure with no reason, which we then ignore at suite
# results reporting time.
raise Exception('')
# If we finish successfully, nothing in autotest ever looks at the
# status.log, so it's purely for human consumption and tracability.
