PyOGP

Overview

AWG (in-world discussion group page) and Linden Lab plan to share the effort in writing a test harness which executes tests against implementations of the Open Grid Protocol (OGP). The intent is not to test SL or OpenSim (or gridX) themselves. Rather, the desire is to create a framework where the implementations of the protocols can be tested in any virtual environment implemented per the Open Grid Protocols as documented. We plan to be able to test at the smallest functional level possible, akin to unit testing, and to have the ability to use the framework to sequence steps to enable state specific tests to be run.

The longer term vision is essentially a client library, capable of navigating the grid and interacting with the various hosts, sitting next to a testing framework, happily running along telling us what works where, and where something needs a little attention to work according to specification...

For a smidge more detail on OGP, see a visual representation of the upcoming projects and a general introduction.

Project Status

• June 26, 2008 - We have begun to write some code to prototype the client library framework. We have also discussed some of the details of the client lib and how we should begin to structure it.

Project Tasks

These are tasks that need to be accomplished for the overall project. Each part of the project (library and harness) also has its own task list.

1. Set up collaboration methods
   • Meeting Times - Enus is out of the Linden Lab office until July 14th. June 28th is unavailable for him, the following week is some silly American holiday, and the following Friday (July 11) is a travel day). July 18th will be the first sc heduled office hours where Pyogp will be a primary topic.
   • Mailing list - should probably set this up as a Linden hosted list...
2. Start planning structure for Pyogp overall (see Pyogp/Specification)
   • ZCA, buildout and eggs have been tapped as components/attributes of Pyogp...
3. Start planning structure for test harness (see Pyogp/Test_Framework)

Recently completed tasks include:

1. (complete?)License - The Apache V2 License has been selected as the license of choice for pyogp (or whatever name we agree upon, see next point).
2. (complete?)Naming (I'd like to not debate for an hour on these. Tao had suggestions, I like em. Please speak up if you have strong reservations about the suggested naming).
   • Python client library name - pyogp
   • Python test framework (unittest/doctest) - ?
3. (complete?)Repository - So Mercurial, aka hg, was looking promising, but we decided internally that we aren't quite ready for that. There is a move toward Mercurial internally, but we need to work this out before moving forward with it on this effort. It is quite possible that this library and test harness work will become a guinea pig for hg with Linden Lab in the open source arena. Until then, I bring you pyogp on SVN: http://svn.secondlife.com/trac/linden/browser/projects/2008/pyogp.
4. (complete?)Contributions - As we are going to be hosting the source code for this, contributions will be subject to Linden Lab's standard contributor's agreement. I hope this doesn't prevent good work here...
