Workflow Module Upgrade

3 November 2005

I rewrote a large portion of jvandyk's workflow module in order to address a number of problems and add some useful features like per-role control of transitions. Read the discussion on Drupal.org for details.

Benefits

fixes several security holes (including forging of the workflow form field) by eliminating hidden fields and checking all input
fixes bug #24487 by allowing manual specification of the first state
introduces node state history (the who and when of each transition) and registers state changes with watchdog
introduces per-role access control for each transition
introduces setting/viewing of all transitions on one screen
cleans up database schema
improves completeness and accuracy of comments
makes code simpler and more more modular
