qpid-config does not properly set some options if value evaluates to False
--------------------------------------------------------------------------
Key: QPID-3533
URL: https://issues.apache.org/jira/browse/QPID-3533
Project: Qpid
Issue Type: Bug
Components: python tools, Tools
Affects Versions: 0.12
Environment: Linux C++ broker with python 2.6
Reporter: Brandon Pedersen
Priority: Minor
PROBLEM STATEMENT:
Some options with the qpid-config tool ignore options which evaluate to False,
most notably a value of 0. In my case I was trying to set the flow-stop-count
to 0 as described here:
http://qpid.apache.org/books/0.12/AMQP-Messaging-Broker-CPP-Book/html/ch01s09.html
to disable the flow control.
STEPS TO REPRODUCE:
- Add a queue using the following options:
qpid-config add queue myqueue --max-queue-count=5 --limit-policy=flow-to-disk
--flow-stop-count=0
- Generate at least 5 messages that will go on myqueue
RESULTS:
Generating the 5th message will hang, waiting for the queue count to go less
than 4
EXPECTED RESULTS:
Messages should continue to flow onto the queue (and be flushed to the disk)
COMMENTS:
The reason this happens is because the flow stop count is never set by
qpid-config. There are several options that share the same issue in
qpid-config. I created a patch that fixes this issue for me and will attach it.
