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

             Summary: CouchDB sends 200 and invalid JSON  if _changes view filter is invalid
                 Key: COUCHDB-2765
                 URL: https://issues.apache.org/jira/browse/COUCHDB-2765
             Project: CouchDB
          Issue Type: Bug
      Security Level: public (Regular issues)
          Components: Database Core
            Reporter: Nolan Lawson


If you provide a {{view}} with {{filter=_view}} in {{_changes}} and the referenced {{view}} is a design doc with no {{map}} function, then the database returns a 200 with invalid JSON.

cURL to reproduce:

{code}
curl 'http://127.0.0.1:5984/testdb/' -X DELETE  -H 'Content-Type: application/json' -H 'Accept: application/json' 

curl 'http://127.0.0.1:5984/testdb/' -X PUT -H 'Content-Type: application/json' -H 'Accept: application/json'

curl 'http://127.0.0.1:5984/testdb/_design/name' -X PUT  -H 'Content-Type: application/json' -H 'Accept: application/json' --data-binary '{"_id":"_design/name","views":{"name":{"empty":"sad face"}}}' 

curl 'http://127.0.0.1:5984/testdb/_changes?timeout=25000&feed=longpoll&filter=_view&view=name%2Fname&since=0&limit=25&_nonce=1438464395669'  -H 'Accept: application/json'
{code}

Result:

{code}
{"ok":true}
{"ok":true}
{"ok":true,"id":"_design/name","rev":"1-214291b1f3879ad7a5f408d3e1edb53b"}
{"results":[
curl: (56) Illegal or missing hexadecimal sequence in chunked-encoding
{code}

The final response from CouchDB is this invalid JSON:

{code}
{"results":[
An error has occurred: {"bytesParsed":0,"code":"HPE_INVALID_CHUNK_SIZE"}
{code}
