[jira] Created: (TAPESTRY-347) Memory leak then reseting pages..
Memory leak then reseting pages..
----------------------------------
Key: TAPESTRY-347
URL: http://issues.apache.org/jira/browse/TAPESTRY-347
Project: Tapestry
Type: Bug
Components: Framework
Versions: 3.0.3
Reporter: Tomas Jucius
Priority: Critical
Here what I have found.. I can't develop my project because of this..
Because it depends on this feature..
As we all know tapestry put all things into pool ant it retrieves it
when you request for page and etc...
My application sometimes need to reset this pool..
So I use reset service..
But after a lot of resets jvm memory becomes full, and I get
"java.lang.OutOfMemoryError"
So after each reset some object are not collected.. And some
references to objects are left.. I could't find where..
if in class AbstractEngine you comment these lines in clearCachedData method
_pageSource.reset();
_pool.clear();
when memory usage stops growing bet pool is not cleared:)..
So I suppose what pool is buggy or something else.. couldn't figure..
TO SEE THIS BUG DEPLOY NEW APPLICATION WITH THESE FILES:
-----------------------------HomePage.java-------------------------------
mport java.io.IOException;
import java.util.Map;
import org.apache.tapestry.IMarkupWriter;
import org.apache.tapestry.IRequestCycle;
import org.apache.tapestry.Tapestry;
import org.apache.tapestry.engine.IEngineService;
import org.apache.tapestry.html.BasePage;
import org.apache.tapestry.util.prop.PropertyFinder;
public class HomePage extends BasePage {
public void beginResponse(IMarkupWriter writer, IRequestCycle cycle) {
// TODO Auto-generated method stub
System.out.println("redirect " +
cycle.getEngine().isResetServiceEnabled() + " " +
(Runtime.getRuntime().totalMemory()) );
redirectToResetService(cycle);
try {
Thread.sleep(200);
}
catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
super.beginResponse(writer, cycle);
}
public void redirectToResetService(IRequestCycle cycle) {
IEngineService resetService =
cycle.getEngine().getService(Tapestry.RESET_SERVICE);
try {
cycle.getRequestContext().redirect((resetService.getLink(cycle,
this, null).getURL()));
resetService = null;
}
catch (IOException e) {
e.printStackTrace();
}
}
}

OPEN YOUR APPLICATION WITH EXPLORER IT HAS NO REDIRECTION LIMIT..
AND YOU CAN SET MAX MEMORY PROPERTY TO: -Xmx3M
IF THEREIS NO ANY COMPONENT in page when it is not leaking (so I put
this insert)..
So maybe of component specifications it is leaking?
Used profiler.. I didn't see growing any tapestry object only
java.util.* classes..
