[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Usage of Timers in JBM 2

by jmesnil

I've removed the 2 TimerTasks used by Netty HTTP code (in r7558). I'll soon commit the removal of 2 other TimerTasks in MessageCounterManager and ResourceManager. Both will also be replaced by Runnabled executed by JBM scheduled thread pool. There remains 2 TimerTasks: * 1 in JBMBootstrapServer to check if there is a STOP_ME file and shutdown the server in that case * 1 in TimedBuffer The one in JBMBootstraspServer will stay. I'm not sure for the one in TimedBuffer. I guess we could also use the global scheduled thread pool for this one but the asyncio code already defines its own thread pools (in AIOSequentialFileFactory). Should it also define its own scheduled executor service or can it use the global one? Clebert, could you comment on this one?

[Design of JBoss jBPM] - Re: current activity of execution

by tom.baeyens＠jboss.com

for the record: i wasn't spanking you. (at least not this time:-) i added that to the docs because you pointed out a hole in the docs. thanks ! anonymous wrote : But still, this doesn't lead to a problem with the getActivityName, or? If I am in a composite, the root execution may be in the scope/composite state, and the child in the "real" state. exactly. the parent execution will have as execution state Execution.STATE_INACTIVE_CONCURRENT_ROOT and it should still point to the scope/composite activity. the leaves point to the real activity. the difference with before is that each activity that has variables or timers declared on it, will also create a child token. the parent execution will be in state STATE_INACTIVE_SCOPE and the (single) child will be in state STATE_ACTIVE_ROOT in that case the parent execution will be in state View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4242883#4242883 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4242883

Kabir, On AS5, I see that the JBoss5ClassPoolFactory is the default factory used if there is no class pool defined. At Branch5_x. I see that the classpool factory is defined as JBossClDelegatingClassPoolFactory. So, is JBoss5CPF ever used? Another question, I didn't get what is TempClassPool for (except for the convert references part) and when is it used.

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Usage of Timers in JBM 2

by jmesnil

I'll rewrite the 2 http timer tasks (one used in NettyConnector, the other in Netty Acceptor) to use our scheduled thread pools instead of timers. I'll update our remoting SPI to pass a ScheduledExecutorService for the scheduled thread pool when creating a connector/acceptor in addition to the regular thread pool View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4242794#4242794 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4242794
