Subject [jira] Commented: (COUCHDB-441) Finally implement pre-write-doc-edit handlers.
Date Sun, 02 Aug 2009 19:39:14 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12738120#action_12738120
] 

Christopher Lenz commented on COUCHDB-441:
------------------------------------------

I think a post-save update function should be exactly analogous to the validate_doc_func feature
already in CouchDB: add a function to the design doc, and have CouchDB invoke it for any document
update.

In fact, this functionality could be part of the validation routine if the doc wasn't made
read-only (and the function returned a new document), saving some overhead.

Am I missing something?

> It would be useful for auditing to have the identity of the user who inserted a new revision
and the timestamp of the operation to be inserted in the document in the same way that the
new revision number is.
> Doing this at the application level is not adequate since it would be readily spoofable
and would bypass the authentication handler.
> There is a comment in couch_db:update_docs about generating new revision ids, but I couldn't
quite comprehend what specific code was responsible for inserting the id into the document.
