"timfox" wrote : | Since isPaging() and addSize() are not done together as an atomic operation, it is possible that many threads could call isPaging() at the same time and return false to all of them. The way it works is... We aways call page(Message) before routing... if (!page(Message)) { route(); addSize(....); } addSize is what starts the page-mode, and addSize is only called after routing. Meaning that anything after that will be routed. You could eventually have simultaneous threads overlapping the maxSize... but I'm not sure if the cost of synchronizing this would be worth. We could maybe add another check on the last addSize. But i don't want to add any synchronization on this. I can double check this after Xmas.

[Design of JBoss ESB] - Re: StartProcessInstanceCommand: Return token id/process ins

by camunda

| Kevin, I believe that you are very wary of signal because the command doesn't know if the process instance is in a known/consistent state | You can set an "expected state" on the jbpm SignalCommand. And I think if you get some really external signal, you need he SignalCommand, or how do you want to get around this? Returning the token id when starting a new process instance is indeed an important use case where already some workarounds have been created because it is not there! So I completly support this requirement. In this thread I think it is a good idea to mention again, that the whole internals of the BpmProcessor are a bit, hmm, let's say hard to understand... Best thing in my eyes is to rewrite it... I wanted to collect issues I have with it but didn't had the time yet...

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Non atomic issue with paging

by clebert.suconic＠jboss.com

So, in summary, when we are actually paging, the only atomic operation you could use is addSize. isPaging will only give the current status of paging for the transaction use-case, but later when the commit is made, we need to verify routing & addSize again.

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: ServerMessageImpl::durableRefCount strange-ness

by clebert.suconic＠jboss.com

This is something you originally wrote, but it seems correct to me. You need that to determine if you are going to delete the message on the same transaction. If rollback is called, the delete won't take effect and the durable will be reverted. Maybe you thought about a different way of doing it now.

I have used '/' in both Windows and Linux, and it has aways worked. We can change that if you prefer. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4197889#4197889 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4197889
