[Design of JBoss Build System] - Snapshots update (mvn -U)

by heiko.braun＠jboss.com

I cannot force the snapshot update. Even when I use the '-U' switch, it checks the remote repositories but doesn't pull the latest artifacts version. Any idea what I might be doing wrong?

Setting journal-sync to false means transactions aren't synched at commit/rollback - they're just written to the OS buffers and the OS lazily writes them. So you get performance at the expense of reliability. With AIO you get performance with no reliability hit (that's the theory anyway) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4149375#4149375 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4149375

[Design of Messaging on JBoss (Messaging/JBoss)] - Declare variables with the interface type

by timfox

I've noticed quite a few places in the code where the implementation type is being used to declare variables, not the interface type, e.g.: | ArrayList myList = new ArrayList(); | Yuck!, should be: | List myList = new ArrayList(); | or: | MessageImpl message = new MessageImpl(JBossTextMessage.TYPE, false, 0, System.currentTimeMillis(), (byte) 1); | Should be: | Message message = new MessageImpl(JBossTextMessage.TYPE, false, 0, System.currentTimeMillis(), (byte) 1); | Please don't use the implementation type in this way, it leaks implementation details and defeats the purpose of the interface/implementation split.

What am I missing here? thats what i assumed, am i right in thinking that the only libs that we need are either libJBMLibAIO32.so or libJBMLibAIO64.so or is there something else that needs installing? Ive updated the standalone distro to ship with these libs so should get used out of the box. When running the perf examples i get no difference in performance between nio and asyncio, in fact when i set journal-sync to false nio is faster. What should i expect?

[Design of JBoss jBPM] - Re: Potential enhancement to jbpm

by tom.baeyens＠jboss.com

"brittm" wrote : Of course, you would have to implement code to reject re-deployment of a process definition that tried to deploy with a version number that was already in use for that definition name, | or even more strickt: the given version number has to match exactly with the expected version number, which is the previous highest version + 1 the motivation for this is auto deployment. if we have such a mechanism, then you can drop your processes in a deploy folder. a deployer can then figure out if the process needs to be redeployed or not. it also keeps the developer in charge of whether he wants to redeploy or not. the designer tool could offer convenience for this by incrementing the version in the source file automatically each time when you deploy. i'm still not totally clear on how to deal with multiple staging environments. where you want to just deploy like we do now in development, but you want the verified deployment in production. a potential solution might be the deployment interceptors that i've just worked out. (a more generic variant of the configurable parser sequence that we have now in jbpm 3). i have one interceptor that does the validation and that one is configured in the configuration file. so if in development you don't want that validation, then you just remove that line in the environment configuration. anyways, all these are many ideas that didn't result into a clean picture for me. so all input like this is certainly welcome. "brittm" wrote : I suppose we're really talking about two different things: the jBPM version_ field is versioning deployments, whereas the developer is versioning content. those two are related. and it's infact that relation that is not always clear. britt, can you ping me in another email. i tried to email you and i got a failure on your account.
