2009-08-27Add task-metadata-track.bbclass, for tracking task changes to metadata.Chris Larson
This class uses events to capture the state of the datastore when the task starts, and after it completes. It diffs those captured states, and emits messages showing which variables changed, and what their values were changed to. It provides a mechanism to blacklist variables you expect to change, both globally and on a per-task basis. Signed-off-by: Chris Larson <clarson@kergoth.com>
