Rob Godfrey commented on QPID-6954:

[~k-wall] On your first point, the function is a converter, not a copier - so I
actually think the current behaviour is more "correct", however the primary use
case here is the REST API calling in with a value, or a static default being
converted - in both cases the map is not going to be changed. As such I think
it would be odd to do a deep copy here when we don't otherwise.
On your second point, I agree an NPE is undesirable. Ideally we should allow
for metadata driven defaulting, however using the Defaults class as you suggest
would seem to give the same behaviour - however I think it should probably only
be used in the case where the key is not present in the map. If the key is
present then we should always use the value for the conversion - even if this
ends up with an NPE.

[jira] [Commented] (QPID-6954) [Java Broker] Add the ability to define "policies" for node auto-creation based on address

Keith Wall commented on QPID-6954:
--
Rob, the changes look good:
Two comments:
* In
{{org.apache.qpid.server.model.AttributeValueConverter.ManageableAttributeTypeConverter#convert}}
the proxy is backed by the Map provided by the caller.If the Map were to
change later, the MAV would change too and I think this behaviour would be
surprising. A deep clone would be most desirable, but this is tricky as the
Map could contain values of any type, which might not be cloneable. I think a
defensive copy of the Map would still be a good idea.
* If the {{ManageableAttributeValue}} has a method that returns a primitive, a
NPE will occur on line
org.apache.qpid.server.model.AttributeValueConverter#convert:1183 if the map
has no value for the attribute or that value is null. We should guard the
primitive case and return the primitive default value
{{com.google.common.base.Defaults}}.

Keith Wall commented on QPID-6954:
--
My comments on the implementation:
* {{AbstractVirtualHost#validateNodeAutoCreationPolicy}} - exception messages
should identify the the NodeAutoCreationPolicy which is at fault. Should
NodeAutoCreationPolicy have a name?
* VirtualHost#getNodeAutoCreationPolicies attribute has no description
* There are no tests for the feature. I would at least expect a test testing
the ability to create a queue and an exchange,
And a comment on the feature itself:
* As a user I can auto create message source and message destinations, but I
can't cause Bindings to come in existence. Is this a gap?
Finally:
There is no UI or end-user docs for the feature - is this required for 6.1?
