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

by clebert.suconic＠jboss.com

isPaging is used only on TransactionImpl. And we are not actually page if isPaging. We are just holding the message until commit is called, when we will actually call addSize and route the message again. This is because I can't page a message for a pending transaction. We don't have control when the commit will come (it could be waiting an user action). Later when commit is called, addSize is used, and the message will only go towards paging, if is in page mode. When we have the HugeTransactionSupport in place, that will be done in another thread. So, when the HugeTransaction is in place, when isPaging = true, we will delay the messages on another file, when commit is called we will transfer the temporary repository towards routing what could lead to paging. On the non-transactional use-case, we aways use addSize. Unless something was recently changed.

Hmm, how about using something like the ProfileService DeploymentManager: http://anonsvn.jboss.org/repos/jbossas/projects/integration/trunk/jboss-p... With this you can deploy a relative deployment from the file system, or you can tell PS to copy a zipped deployment into the deploy/ dir. Both ways will include it in the hotDeployment checking. There is also an API (on the Profile itself) to disable checking for modified deployments. NOTE: we are going to work on this API in the next weeks, so we can definitely have a look and see how we can simplify things for you. I can point you to a testcase in the AS testsuite if you want to give this DeploymentManager a try :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4197850#4197850 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4197850

Is this done yet? (Doesn't look like it). If not, please make sure it is tracked in a JIRA. Actually, can you look through all the paging and large message threads and make sure everything that is not complete yet is tracked properly. It seems we have some loose ends here.....

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

by timfox

The way paging currently works, the isPaging() check is done first before the message is routed, then later the pagingStore.addSize() method is called. 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. Then later they all call addSize() and the system runs out of memory. To guarantee we don't run out of memory isPaging() and addSize() would have to be combined in a single atomic operation.

Why is durableRefCount decremented in a transaction *before* it is committed? Surely it should be decremented when it is committed?
