Subject [jira] Updated: (DERBY-1471) Implement layer B streaming for new methods defined in JDBC4.0
Date Tue, 05 Dec 2006 11:22:22 GMT
     [ http://issues.apache.org/jira/browse/DERBY-1471?page=all ]

Tomohito Nakayama updated DERBY-1471:

    Attachment: DERBY-1471_3.patch

I upload the DERBY-1471_3.patch.

* Description of the patch 
   * This patch implements Layer B streaming for new methods defined in JDBC4.0 as next. 
      * Derby NetClient sends lengthless LOB information in Layer B streaming. 
      * Derby NetworkServer receives LOB information sent via Layer B streaming. 
   * Remarkable difference from previous patch 
      * The error messagewas modified.
      * Verbose type checking code for casting to NetConnection type was removed.

 * Test of the patch 
   * Executed org.apache.derbyTesting.functionTests.suites.All on jdk16 rc environment and
found no error.
   * Execute derbyall on jdb16rc environment and found no error except for intermittent error
of derbynet/testSecMec.java in DerbyNetClient framework.

> JDBC 4.0 introduced new methods which take parameters for object to be sent to sever
without length information.
> For those methods, Layer B streaming is best way to implement sending object to server.
> This issue is representation of DERBY-1417 in Network Client.
