| Michelle Caisse 2007-08-17, 1:12 pm |
| Attendees: Matthew Adams, Michelle Caisse
Matthew is working on standard enhancer and schema management classes
and the associated SPI.
His patch dealing with PMF properties "name" and "persistenceUnitName"
have been checked in (JDO-496). Seems to work.
Michelle is working on tests for relationship integrity on flush() when
the application changes one side of the relationship (spec 15.3).
Craig is working on spec updates for persistent properties.

| Matthew and All,
Do you also have ClassFileTransformer for transparent runtime enhancement with
JRE 5 ?
usage example:
------------------
java -javaagent:jdo-2.1.jar -Djavax.jdo.enhancer.class=acme.EnhancerImpl <MAIN>
alternative command line:
java -javaagent:jdo-2.1.jar=enhancer.class=acme.EnhancerImpl <MAIN>
Implementation
-------------------------------------
package acme;
public class Enhancer
{
public Enhancer() {}
public byte[] enhance(final String className, byte[] classdefinition,
ClassLoader loader)
{
return bytecodemodified;
}
}
--------------------------------------
package javax.jdo.enhancer;
public JDOClassFileTransformer implements ClassFileTransformer
{
public static void premain(String agentArguments, Instrumentation
instrumentation)
{
instrumentation.addTransformer(new JDOClassFileTransformer());
}
public byte[] transform(ClassLoader loader, String className, Class
classBeingRedefined, ProtectionDomain protectionDomain, byte[] classfileBuffer)
{
Enhancer enhancer = new instance of class defined at
System.getProperty("javax.jdo.enhancer.class")
return enhancer. enhance(className,classfileBuffer,loader
);
}
}
