Subject [jira] Commented: (COUCHDB-973) Return 410 when GETing a previously deleted document (rather than 404)
Date Thu, 13 Jan 2011 19:11:46 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-973?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12981425#action_12981425

Paul Joseph Davis commented on COUCHDB-973:
-------------------------------------------

The fact that 410's can be cached makes me even more hesitant to switch over to them because
unless clients are sending the etags from possibly unknown previous entries it would seem
like a bad possibility of masking a re-created document. Which seems like a reason why they
would have said if we know that a resource can be recreated to use 404.

We don't keep anything similar at the db level so I don't think that's really affected by
this.

> When you GET a nonexistent doc you get (as you should) a 404 Not Found error. However,
if you GET a document that has previously existed you also get the 404 response. It would
be more informative (IMO) for the 410 Gone response code to be used. 410 Gone's intention
is for exactly this use case, and it could have some value to CouchDB developers who need
to know the document did exist.
> CouchDB is already half way there as in the body of the 404 response it does state that
the document did exist (at least prior to compaction), so outputing a 410 (again, prior to
compaction) would hopefully be a trivial patch.
