Description Gordon Sim 2008-07-24 17:25:19 UTC

When invoking SubscriptionManager::get() with a non-zero timeout the expectation
is that if a message is not on the queue at that time the thread will block for
the desired time waiting for one to arrive.

However a flush is issued before the wait starts. This means that if the queue
is empty at that point no message will be sent but the credit will be set to
zero and so when a message does arrive it won't get delivered.

Comment 1 Gordon Sim 2008-07-25 10:26:27 UTC

Fix applied on trunk (r679739) and qpid.0-10(r679748).

Comment 3 Frantisek Reznicek 2008-09-12 12:33:10 UTC

RHTS test (MRG_Messaging/qpid_localqueue_timeout_bz453599) implements SubscriptionManager::get() test with non zero timeout and proves that SubscriptionManager::get() now correctly waits. (ON_QA->VERIFIED)
