Re: [Wicket-develop] sychronize around session object

[Johan Compagner]

thread.interrupt() will only work for blocking io. (or wait) You can't just interrupt a running thread. There is no way to do that in java. (thread.stop() can't be used and that is also a thing you don't want to do) second you don't have any idea which thread handles what at the moment.. And if you just "crash" the thread then the components /models can be in a complete invalid state. So just let it go is the only thing that can be done.

If so, call Thread.interrupt() on it or signal interruption in some other manner, *then* lock on the session. The benefit here is that if a user hits REFRESH multiple times quickly, we don't fall behind trying to render pages when they have been aborted. I know how to implement this easily under JDK 1.5 (using java.util.concurrent.Lock) but I'm not sure how you could do it using older JDKs... Still, I think it is a great idea and would give Wicket a huge advantage over other frameworks from a scalability point of view.

The problem occured when one user (one session) refreshed quickly. So, as the synchronizations happens for a session, the scalability is not reduced.

I think I understand the change, but is there a possibility that it could ever happen and thus requires synchronization? It can if two users hit a Page at the same time (I think). Thing is, I think that synchronizing Page rendering by default isn't necessarily a good thing. It simplifies things but it'll also reduce the scalability of Wicket.
