Strangecodebase branch 2.0 dev
--------------------------------------------------------------------------------

Codebase self contained. runs without reference to external files or info.
    - can be located in /usr/local/php/lib/php for server-wide access
    - does not include any files outside codebase
    - does not write to files outside codebase
    - does not try to determine it's location or site parameters. this will minimize it's failure to glean this info.
    - will still run if info missing: db creds, log dir, session info.
    - can be located in /usr/local/lib/php if necessary, so accessible by all sites.
    
remove interdependencies:
    - App() is the only dependency for other classes. It includes Utilities.inc.php silently.
    - admin_id vs. user_id
    - libs requiring external files, such as html templates and email templates, make classes self-contained.
    
App object:
    - object belongs to a realm, keeping messages and session data within specific site/app.
    - uses the singleton pattern so only one instance of App exists for each app.
    - app object can be accessed globally without reference to object name by calling methods statically, e.g. App:logMsg()
    - seperate application and codebase parameters from site configuration variables. 
      Use $app->getParam('var') or App::getParam('var') to get app params and for site configurations do whatever you want
      I'm using $cfg['node']['features'] format for configurations
    
Application configuration vars
    - defaults part of the app class
    - do not need to be set in any specific order

One application will always have distinct:
    - Configurations:
        - log dir
        - log config
        - debugging
        - charset
        - maybe sessions
    - Objects:
        - auth object
        - security roster
    - Environment:
        - even seperate codebase installs if necessary
        - include path
        - site/doc/web root
        - lang
    - $dbh database handler
      
DB object:
    - Self contained class for DB functions. db::query is the only necessary function. Maintains connections and state independent of App.
    
Things with modified interfaces:
    - App
    - Auth_SQL
    - DB
    - DBSessionHandler.inc.php
    - RecordLock
    - RecordVersion
    - SessionCache.inc.php

Full test suite for all codebase libraries. Run from the command line: "codebase/tests/run_tests.sh;"

Classes that access database tables have a function initDB() that will setup the basic schema necessary to run. This includes Auth_SQL, RecordVersion, RecordLock, and DBSessionHandler.

Strangecodebase branch 1.0 release
--------------------------------------------------------------------------------

This is the primary stable release used before we started using Subversion. It was maintained erratically by one erratic person. No revision info documented, sorry.
