Manager.handle_waiting

Manager.handle_waiting(conn, new_idle_count, read_receipt)

Record that an employee is idle with nothing to do.

There is a race condition that is corrected here. If an employee sends a waiting message at the same time that its boss sends it a task, the boss’s idle count will eventually be incorrect. To fix this, every waiting message sent by an employee is accompanied by a read receipt of the latest batch of tasks it has processed. The boss can then adjust the idle count by the number of tasks sent since the read receipt.

Return type:

None
