Well that one is easily taken care of: just use a local variable to
indicate whether the processing was interrupted or went to completion.
You would probably simply use a boolean or constant integers to indicate
the exit status, but I'll write it here with a string for simplicity:
class FooWorker < BackgrounDRb::MetaWorker
def some_work(args=nil)
job_exit_status = 'FORCEABLY_DELETED'
begin
# Large batch job here
...
rescue
job_exit_status = 'ERRORED_OUT'
# Error processing here
...
else
job_exit_status = 'FINISHED_NORMALLY'
ensure
case job_exit_status
when 'FINISHED_NORMALLY'
# Your normal ending cleanup code here
...
when 'ERRORED_OUT'
# Your error ending cleanup code here
...
else
# Your "delete_worker" ending cleanup code here
...
end
end
end
end
Of course this still all assumes that delete_worker is *not* the "kill
-9" hemant suggested, and that it will let your ensure clause run. Have
you tried it out yet? Let us know how it goes.
Cheers,
