[DISCUSS] OODT-215: Current Status and 0.4 release candidate

["Mattmann, Chris A (388J)" <ch...@jpl.nasa.gov>]

Hey Guys,

I am nearing completion on OODT-215 [1]. Yes, for real. Check this out:

http://minus.com/moumqrviB/

I even drew a picture to illustrate. Basically everything in yellow I've implemented.
That diagram in many ways constitutes most of the new contributions of Workflow2
that are still on the critical path. The best part? All of that yellow code is unit tested
and tests are passing every night on our Jenkins server. The things left to implement
are basically:

1. Wire up the RunnerThread to periodically poll the TaskQuerier for the next Task in the
list of Runnable, Prioritized and sorted tasks to execute (that is constantly being re-prioritzed).
2. Hand that task off to the Workflow Runner framework for execution.
3. Finish tying the State model to the new Workflow Processor framework in place. 

Yes, not lying, that's pretty much it. If I can get 1-3 working, we're basically in business
for Workflow2. I will also at that point quickly whip up a back compat layer so that 
the old Workflow engine model (ThreadPoolWorkflowEngine) will still work, but 
I'm really shooting to wrap up OODT-215 this week and get 0.4 out the door.

So, please, all, if you can, help me get there. When I throw something up on ReviewBoard
and/or anything else, I'd appreciate your help and eyes. And if you actually understood
what I said above and can contribute, would love it anywhere and any place. Thanks!

Paul, I assume you can roll the 0.4 RC this weekend?? :) For real this time.

Cheers,
Chris
