Subject [jira] [Updated] (QPID-4177) Writing wrong filter in a QMF method causes the filter is ignored
Date Wed, 08 Aug 2012 14:35:20 GMT

     [ https://issues.apache.org/jira/browse/QPID-4177?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Pavel Moravec updated QPID-4177:
--------------------------------

    Attachment: 0001-QMF-filters-on-queues.patch

The patch fixes two similar bugs:
1) if proper filter matches 0 messages, then the QMF response is "InvalidParameter" - that
is corrected to "OK" response
2) filter with invalid syntax moves all messages instead of none (this JIRA).

It assumes UINT32_MAX (resp. UINT_MAX) value is used for error response and does not mean
number of purged / moved messages from a queue.

> Invoking e.g. method for moving messages from a queue to another with an invalid filter
like:
> (in qpid-tool)
> call 120 queueMoveMessages SrcQueue DstQueue 0 {'qpid.subject':'key2'}
> will produce an error in qpidd log:
> 2012-07-31 11:50:14 error Ignoring unrecognized message filter: '{qpid.subject:key2}'
> but the messages are moved from SrcQueue to DstQueue. So having an invalid filter in
a QMF method raises an error log but otherwise the filter is ignored and method applied. And
the method returns zero as usual.
> The correct way would be not performing the method, as invalid parameter has been supplied.
