-----------------------------------
Summary: [AMQP] sender is not granted credit once space on queue
is available
Key: ARTEMIS-1898
URL: https://issues.apache.org/jira/browse/ARTEMIS-1898
Project: ActiveMQ Artemis
Issue Type: Bug
Reporter: Gordon Sim
Attachments: drain.py, test_send.py
If an AMQP publisher sends to a queue that is full, with
address-full-policy=FAIL, it gets messages rejected and no credit issued as
expected. However if the queue is then drained, that existing sender link is
not granted any more credit.
To reproduce, configure a broker such that it has a queue called examples with
some fairly low max size (I set global-max-size to 100kb) and
address-full-policy of FAIL. Then run attached test_send.py with args e.g. -m
100000. The sender will eventually stall due to lack of credit. Then run the
attached drain.py which will drain the queue. This *should* allow the sender to
resume sending, but it does not.
