[Design the new POJO MicroContainer] - Re: Deployers Ordering Issue

by richard.opalka＠jboss.com

My idea how to fix it: ad1) Put all deployers to the same collection (not list per stage like current impl) ad2) on deployers chain retrieval * check whether sorting needs to be done (yes if deployers were added/removed to/from the chain from last getDeployersList() method call) * sort all deployers if change is detected only ad3) Return all deployers belonging to requested deployers chain (getDeployersList() method call) from sorted list of deployers NOTE: Sorting algorithm have to take deployment stages, inputs, outputs and relative order into account. Current algorithm based on comparing two deployers doesn't include all possible usecases and it ignores inputs and stages.

No, deployment stage is something different, and imho it shouldn't have anything to do with explicit ordering. Like I said, the only logical thing for me is that dev phase check, everything else is just laziness --> more performance suffering boot time. ;-( View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4240021#4240021 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4240021

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Journal Cleanup and Journal Compactor

When compacting you don't touch the information in memory. So if an update or delete comes in you just update as normal. Then when the compacting is done you just do a quick switch over in memory. I don't see why you need to cache anything.

[Design the new POJO MicroContainer] - Re: MC tools

I moved the existing code to a sub-project of mc-tools, so that we can have multiple tools under separate release lifecycle.

They all input JBWD and output JBWMD, which is completely valid, if they don't interfere with each others JBWMD usage/setup/config. But if they do, I very much doubt that there exist a simple (read fast and declarative) algorithm that would order you that. ;-) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4240009#4240009 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4240009
