CouchDB - Views not being updated after delete

I have a view similar to this (a contrived example):

function(doc) {

if (doc.attrib) { emit([doc.attrib],doc._id) }

}

Everything works as expec开发者_C百科ted until the data is deleted. I get this crazy scenario where there is no data in the actual database (confirmed via _all_docs and _changes run on curl as well as all_documents on Futon). However the view still yields data (again on both curl and Futon).

The delete comprises Bulk delete and purge operations via ektorp. Running _changes after each confirms these work as expected. re-creating the view makes it reflect the true state of the documents in the DB.

Have I missed something obvious here or are views in CouchDB only incremental?

Did you really _purge the data? That should invalidate the view and cause a full rebuild. I'll note that _purge is not recommended for normal use. It exists only for accidents like putting your plaintext password in a document.

You may have exposed a bug in _purge, though, so if you can reliably induce this with _purge but not if you just delete, I encourage you to file a ticket on our JIRA (https://issues.apache.org/jira/browse/COUCHDB).

I'll note also that the fix will be to blow away the index if you purge, there is no incremental approach possible (you are literally removing the information that an incremental approach requires).
