Subject [jira] [Updated] (COUCHDB-2226) Wrongful query_parse_error on group_level=999, keys.length > 1
Date Thu, 17 Apr 2014 05:47:15 GMT

     [ https://issues.apache.org/jira/browse/COUCHDB-2226?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Nolan Lawson updated COUCHDB-2226:
----------------------------------

    Description: 
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}

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.
