[jira] Created: (QPID-447) C++: Race in topic test
C++: Race in topic test
-----------------------
Key: QPID-447
URL: https://issues.apache.org/jira/browse/QPID-447
Project: Qpid
Issue Type: Test
Reporter: Alan Conway
The topic test has a race condition. It's masked for now with a sleep in cpp/src/tests/topictest.
If the publisher starts publishing before all the listeners are listening, then some listeners can miss some messages. This can cause a short topic test to hang, as some listeners may miss *all* the messages, including the report-request, and therefore never send a report.

[jira] Updated: (QPID-447) C++: Race in topic test
Posted by "David Sommerseth (JIRA)" <qp...@incubator.apache.org>.
[ https://issues.apache.org/jira/browse/QPID-447?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
David Sommerseth updated QPID-447:
----------------------------------
Attachment: topictest_statusqueue.patch
This patch gives an extra argument to topic_listener and topic_publisher, --status-queue. This defines a queue where the publisher will check if all expected listeners are ready or not. The publisher will wait until the right number of listeners have given a ready message.
The queue must be created before topic_publisher/topic_listener is run. The queue must be deleted manually afterwards as well.
qpid-config add queue topic_status
topic_publisher --status-queue topic_status
topic_listener --status-queue topic_status
qpid-config del queue topic_status
