-------------------------------------
Summary: Clarify Editor.childNodeChanged()
Key: OAK-2413
URL: https://issues.apache.org/jira/browse/OAK-2413
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core
Reporter: Marcel Reutegger
Priority: Minor
The current contract for {{Editor.childNodeChanged()}} does not specify if this
method may also be called when the child node did not actually change. The
method {{NodeStateDiff.childNodeChanged()}} explicitly states that there may be
such calls. Looking at the implementation connecting the two classes,
{{EditorDiff.childNodeChange()}} simply calls the editor without checking
whether the child node did in fact change.
I think we either have to change the {{EditorDiff }} or update the contract for
the Editor and adjust implementations. E.g. right now, PrivilegeValidator
(implements Editor), assumes a call to {{childNodeChange()}} indeed means the
child node changed.
