Overview

AWG 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...

Open Topics

  1. 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.
  2. 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...
  3. License - The Apache V2 License has been selected as the license of choice for pyogp (or whatever name we agree upon, see next point).
  4. 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) - ogptest
  5. Discussion Times - Despite Enus heading out for a 3 week vaca on the right coast of the usa, I'll set up an office hours time of sorts to meet with AWG and Lindens to chat about progress and next steps. Coming soon to a gcal near you.

Components (and supporting environmental details)

Initial stubs at a library codebase and directory structure can be found here using your favorite Subversion client: https://svn.secondlife.com/svn/linden/projects/2008/pyogp/
Disclaimer*: Everything in the repo now will change dramatically in the next few weeks as things firm up structure wise. My desires for the work include: a simple, well defined library, a separate test framework (unittest, the initial high level code to be added this week), an samples/examples sandbox, and clean well commented code. That said, none of the above are in place now. They will be. More sophisticated implementations can evolve over time, or can be included on the side of the library...

These are the currently envisioned components.

  1. Login
  2. Caps (and while it's around the UDP pipe)
  3. Message Handlers (see chttp)
  4. Basic web server parts for the Agent, Region and grid bits (ideally a snap in framework)
  5. Test framework - unittest, doctest
  6. Test data (I put this here, not really as a component of the harness, more as a "i'm not telling you my test account's password and what are we gonna do about it" thing)


Tao Takashi has hit the ground running with an experimental framework which has been made available here. Read more at his blogpost describing the start of his work at his very long url. Once a repository is available, I'd plan to pull this in.

Please add to the list as you see fit. The more we throw in here, the better off we are in the long run.
