Jesse Kuhnert resolved TAPESTRY-346:
------------------------------------
Resolution: Won't Fix
If there is a discernable patch or issue logged that someone could follow and
do something about it will likely be fixed.
> Memory leak then reseting pages..
> ---------------------------------
>
> Key: TAPESTRY-346
> URL: http://issues.apache.org/jira/browse/TAPESTRY-346
> Project: Tapestry
> Type: Bug
> Versions: 3.0.3
> Environment: windows xp
> 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.engine.IEngineService;

> 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..
> Appreciate all your notes...
