[jira] Created: (QPID-1961) widen viewMessages(int From, int To)
and getMessageCount() AMQQueueMBean methods to use Long values
widen viewMessages(int From, int To) and getMessageCount() AMQQueueMBean methods to use Long values
---------------------------------------------------------------------------------------------------
Key: QPID-1961
URL: https://issues.apache.org/jira/browse/QPID-1961
Project: Qpid
Issue Type: Sub-task
Components: Java Broker, Java Management : JMX Console
Affects Versions: M4, M3, M2.1, 0.5
Reporter: Robbie Gemmell
Assignee: Robbie Gemmell
Priority: Minor
The viewMessages() operation is inherently limited to viewing the first 2^31 undelivered messages on the queue at any given time due to its use of int parameters. Equally, getMessageCount() returns an int value. However, the SimpleAMQQueue implementation is not limited to 2^31 messages and so there is potential that not all messages can be viewed.
This should be rectified by increasing the parameter range to Long. The viewMessages() implementation will then be limited to viewing ANY 2^31 messages on the queue as the TabularData OpenData result sets used to support generic JMX clients are also fixed in size by an int index.

Robbie Gemmell updated QPID-1961:
---------------------------------
Fix Version/s: 0.6
Summary: widen viewMessages(int From, int To) AMQQueueMBean method to use Long values (was: widen viewMessages(int From, int To) and getMessageCount() AMQQueueMBean methods to use Long values)
changing getMessageCount() from an Integer return type to Long will break compatibility with the JMX CLI. As filling a queue with 2^31 messages involves an extreme amount of memory it is not a typical scenario at present and so changing this will be postponed until future alterations to the management API necessitate a general break in compatibility.
