[QosOrch] The notifications cannot be drained in QosOrch in case the first one needs to retry (#2206)
What I did Bugfix: The notifications cannot be drained in QosOrch in case the first one needs to retry Why I did it Bugfix How I verified it Mock test and manual test. Details if related This is because both doTask and the table handlers take consumer as the argument. In doTask, each notification is iterated in the main loop and passed to table handlers. However, consumer is passed to table handlers, which makes it unable to access the rest notifications following the first one. In case the first one needs to retry and remains in m_toSync, the rest notifications do not have opportunity to run. Signed-off-by: Stephen Sun <[email protected]>
