[jira] [Commented] (COUCHDB-1330) provides() does not supports returning a status code or headers

["Nathan Vander Wilt (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/COUCHDB-1330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13215843#comment-13215843 ] 

Nathan Vander Wilt commented on COUCHDB-1330:
---------------------------------------------

This regression was introduced by https://github.com/apache/couchdb/commit/92f70219ce5ba487e4eb65dea7d16a9168a8547f#share/server/render.js for [#COUCHDB-1272] and also breaks returning "json" instead of "body". Jason's patch looks good to me for fixing it, and I'd love to see it applied soon.

> An Iris Couch user lost the ability to redirect from a provides() callback in a show function: http://getsatisfaction.com/iriscouch/topics/_provides_method_not_returning_code_and_headers
> This show function no longer works:
> function (doc, req) {
>     provides('html', function () {
>         return {
>             headers: { Location: 'http://www.iriscouch.com' },
>             code: 302,
>             body: 'Redirecting to IrisCouch website...'
>         };
>     });   
> }
> This looks like a regression from 1.1.0; although there are no unit tests so perhaps strictly speaking it was unsupported functionality. Git bisect places the error at the patch to COUCHDB-1272.
