Subject [jira] [Created] (COUCHDB-2226) Wrongful query_parse_error on group_level=999, keys.length > 1
Date Thu, 17 Apr 2014 05:47:14 GMT
Nolan Lawson created COUCHDB-2226:
-------------------------------------

             Summary: Wrongful query_parse_error on group_level=999, keys.length > 1
                 Key: COUCHDB-2226
                 URL: https://issues.apache.org/jira/browse/COUCHDB-2226
             Project: CouchDB
          Issue Type: Bug
      Security Level: public (Regular issues)
            Reporter: Nolan Lawson


It's expected that `group=true` will avoid the query parse error if keys.length > 1, but
since `group_level=999` is semantically equivalent to `group=true`, one would expect that
it would also avoid the error.  However, it doesn't.

Tested against CouchDB 1.5.0.  The script below will repro the error.

{code}
DB=http://localhost:5984/mytestdb
curl -X DELETE $DB
curl -X PUT $DB
curl -X PUT $DB/_design/ddoc -H 'content-type:application/json' -d '{"views" : {"view" : {"map"
: "function (doc){emit(doc._id);}", "reduce" : "_count"}}}'
curl -X POST $DB/_bulk_docs -H 'content-type:application/json' -d '{"docs" : [{"_id" : "1"},
{"_id" : "2"}]}'

# returns 2 results
curl -g "$DB/_design/ddoc/_view/view?group=true&keys=[%221%22,%222%22]"

# throws a query_parse_error
curl -g "$DB/_design/ddoc/_view/view?group_level=999&keys=[%221%22,%222%22]"
{code}
