[Opensim-dev] [ CommandServer ] Draft 1

[Impalah]

Hi everybody:

+ 1 for the idea, this first. Opensim needs this command center like we the
air to breathe. I hate to use direct access to DB and dirty tricks to launch
comands.

I have some suggestions, taken from Drupal CMS (http://drupal.org).

The first are roles and permissions. Now, as Melanie says, it's hardcoded
but could be a good idea to take out that code and "give" the permission
info reading from some repository. Could be more levels than one GOD and
even every action in a region could be assigned to a concrete role. One
thing I think Opensim lacks is some flexibility into the hundreds of
harcoded parts.

The second idea is a module for drupal I use frequently: Services (
http://drupal.org/project/services)
This module allows to use drupal framework from external services and using
whatever protocol (xml-rpc, htpp, REST...). The conversion from php is quite
easy and has come great things like uniques uuid by server.

About commands... well, I had to do some services similar to the pretended
Command Center and found useful some Patterns, concretely "Command Factory"
(with its "Command Context" pattern). To create new commands is like a
children game.

I hope my comments helped you...

Greetings
