History: Orphan preferences
Source of version: 2
Copy to clipboard
New in ((Tiki25)), it permits to clean out ((Preferences)) for previously used but later removed features in Tiki.
Why is this needed? As a policy, Tiki doesn't delete data with site admin's consent/knowledge. So when a feature is removed, what do we do with the associated data? Database tables are renamed to make it easy for an administrator to review and delete manually (or keep/move/etc.). However, preferences are just kept until a Tiki admin deletes them.
__As of Tiki25, please consider this feature as experimental. Only use it if you are an experienced Tiki administrator.__
There is likely some data here that is actually still used, but in a non-standard way, so it fools our script.
