Subject [jira] Updated: (DERBY-3578) DrdaStreamOutBufferSize attribute of NetworkServerMBean should be of type int instead of String
Date Mon, 31 Mar 2008 08:42:24 GMT

John H. Embretsen updated DERBY-3578:
-------------------------------------

    Attachment: d3578_v01.diff

Attached a patch (d3578_v01.diff) implementing this improvement and modifying a test accordingly.
Changed files are:

M      java/drda/org/apache/derby/impl/drda/NetworkServerMBeanImpl.java
M      java/drda/org/apache/derby/mbeans/drda/NetworkServerMBean.java
M      java/testing/org/apache/derbyTesting/functionTests/tests/management/NetworkServerMBeanTest.java

I have run suites.All with this patch (jdk1.5) and saw no failures apart from DERBY-3561.
Requesting review.

Since this involves a change of a public interface that is new in 10.4, it would be great
if this could be committed to the 10.4 branch (and trunk) as soon as possible (before creating
the release candidate), to avoid potential compatibility issues.

> The DrdaStreamOutBufferSize attribute of org.apache.derby.mbeans.drda.NetworkServerMBean
is currently of type String. The value of this attribute describes the size of the buffer
for streaming blob/clob from server to client (derby.drda.streamOutBufferSize property), and
is handled as an integer (int) in the DDMWriter class of the Network Server.
> The type was changed to int in the functional specification of DERBY-1387 [1], since
no reason was found for this to be a String. Similar attributes, such as DrdaMaxThreads, have
return type int. It may useful for a JMX client to know that the value should be an int instead
of just any arbitrary string; hence this change.
