returnbody parameter is ignored when bucket type has a true 'write_once' property [JIRA: RIAK-2396]

[bashoshaun]

The body of an HTTP is not returned when inserting an object into a bucket with write_once enabled, even when the returnbody parameter is true. Example:

# ./riak-admin bucket-type create write_many
write_many created
./riak-admin bucket-type activate write_many
write_many has been activated
# ./riak-admin bucket-type create write_once '{"props": {"write_once": true}}'
write_once created
./riak-admin bucket-type activate write_once
write_once has been activated

# Insert an object with a random key into a regular bucket, see how the body is returned
curl -v http://localhost:10018/types/write_many/buckets/testbucket/keys?returnbody=true -H 'Content-Type: text/plain' -d 'test data'

[Basho-JIRA]

Can anyone confirm if this is intended? Should there be no returnbody option on write once buckets? I think this should be fairly easy/quick to confirm and then we can let the customer know and close the ticket.

Thanks, Dan
