                 Key: JCR-2714
                 URL: https://issues.apache.org/jira/browse/JCR-2714
             Project: Jackrabbit Content Repository
          Issue Type: Improvement
          Components: jackrabbit-core
    Affects Versions: 2.2.0
            Reporter: Michael Dürig

I would like to be able to selectively disable checks in ItemValidator in the 
scope of an operation performed through methods of the SessionState class. 
Doing so would provide simple means for internally modifying (for example) 
protected items. Currently such modifications must be done 'manually' on the 
item state level. This approach is very error prone and not very DRY.

With my upcoming patch in place, setting a protected property would look like 
this:

final Node parent = ...
final Value value = ...
SessionState sessionState = sessionContext.getSessionState();

Property property = sessionState.performUnchecked(new 
SessionOperation<Property>() {
    public Property perform(SessionContext context) throws RepositoryException {
        return parent.setProperty("foo", value);
    }
}, ItemValidator.CHECK_CONSTRAINTS);

That is, users need to have access to the session context in order to disable 
checks which makes this only usable from inside Jackrabbit.
