[QPID-6033] [C++ broker] Session statistics sessUnacked wrongly updated

• Type: Bug

• Priority: Trivial

Description

sessUnacked counter for a subscriber gets updated only when re-issuing credit on the session (session.completed AMQP 0=10 performative is received). While it should be updated also on accepting messages (message.accept performative).

Reproducer:

qpid-send -a "testQ; {create:always}" -m 123 --content-size=10
qpid-receive -a testQ -f -m 10000 --ack=100 --print-content=no &

Now, qpid-stat shows queue depth is 23 and 100 dequeues, but qpid-stat -u shows sessUnacked=123.

(sessUnacked will drop after 500 messages are received, due to default qpid-receive option --capacity=1000).
