> Show returning zero length string results in scary errors
> ---------------------------------------------------------
>
> Key: COUCHDB-593
> URL: https://issues.apache.org/jira/browse/COUCHDB-593
> Project: CouchDB
> Issue Type: Bug
> Components: JavaScript View Server
> Affects Versions: 0.10
> Environment: Ubuntu 9.10
> Reporter: Roger Binns
> Assignee: Chris Anderson
>
> If your show function returns a zero length string then several scary things
> happen. Arguably the empty length string should just be returned to the
> browser.
> function (doc,req) { return "";}
> On returning the zero length string, the following is displayed in the
> browser:
> {ret_proc,{proc,<0.79.0>,<<\"javascript\">>,\n
> {couch_os_process,prompt},\n
> {couch_os_process,set_timeout},\n
> {couch_os_process,stop}}}]}"}
> The following is in the CouchDB log:
> [Sun, 06 Dec 2009 22:10:15 GMT] [error] [<0.64.0>] OS Process Error ::
> {render_error,<<"undefined response from show function">>}
