-------------------------------------------

             Summary: Allow validate_doc_update.js to be aware if the update went through
an update function before
                 Key: COUCHDB-1519
                 URL: https://issues.apache.org/jira/browse/COUCHDB-1519
             Project: CouchDB
          Issue Type: New Feature
          Components: Database Core
    Affects Versions: 1.2
            Reporter: Damjan Georgievski


It would be useful for the validate_doc_update function to "know" if the document has been
processed by an update function or is sent directly to the DB.

There are several possible ways to do it:
* allow the update function to update either the userCtx or the secObj objects, and let that
change propagate to the validate_doc_update function
* add a completely new object that will be passed to both functions. update functions could
then modify it.
* add some flag to validate_doc_update parameters to signal that the document is direct to
DB or not. But this would limit the usefulness of the feature.

Adding special attributes to the document object, in an update function, that the validate
function can check later, is not sufficient since that attribute can be sent directly to the
DB also, and will be stored in the database.
