[MB-6736] Querying a view on a single node gives inconsistent_state error if bucket is empty

Wed, 10 Oct 2012 07:17:16 -0500

This is reproducible on both build 1762 or repo sync + latest couchdb master

Steps to reproduce:
1. Create default bucket(1 replica) and 1024 vbuckets.
2. Do no load any data
3. Create a view

curl -v -X PUT -H 'Content-Type: application/json' 'http://Administrator:asdasd@127.0.0.1:9500/default/_design/dev_d1' \
-d '{"views":{"v3":{"map":"function(doc){\nemit(doc._id,doc.n2);\n}"}}}'
bash> curl -v -X PUT -H 'Content-Type: application/json' 'http://Administrator:asdasd@127.0.0.1:9500/default/_design/dev_d1' \
> -d '{"views":{"v3":{"map":"function(doc){\nemit(doc._id,doc.n2);\n}"}}}'

4. Query the view
curl -X GET 'http://Administrator:asdasd@127.0.0.1:9500/default/_design/dev_d1/_view/v3?stale=ok'
