Subject [jira] Commented: (COUCHDB-898) Allow provides() to handle "raw" MIME Type declarations as well as "shortcut" names
Date Wed, 17 Nov 2010 13:01:18 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-898?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12932938#action_12932938

Jan Lehnardt commented on COUCHDB-898:
--------------------------------------

I tried testing it with this:


 // test the provides mime matcher with long mime type names
 xhr = CouchDB.request("GET", "/test_suite_db/_design/template/
   headers: {
     "Accept": 'text/html,application/atom+xml; q=0.9'
   }
 });
 var ct = xhr.getResponseHeader("Content-Type");
 T(/charset=utf-8/.test(ct))
 T(/text\/html/.test(ct))
 T(xhr.responseText == "Ha ha, you said \"plankton\".");

but I got errors:

                                <<"function raised error: (new TypeError(\"weighted[weighted.length

>             Project: CouchDB
>          Issue Type: Improvement
>          Components: JavaScript View Server
>    Affects Versions: 1.0.1
>            Reporter: Benjamin Young
>            Priority: Minor
>             Fix For: 1.0.2
>
>         Attachments: provides_reverse_content_type_lookup.diff
>
>
> Right now, provides() only supports the content types declared via registerType() if
they're selected using the shortcut names used in main.js (or render.js in trunk). Without
a list of those "laying around" a developer will likely submit a raw MIME Type vs. using the
shortcut name.
> For example,
> provides("text/calendar", ....);
> currently fails because you need to use:
> provides("ics", ....);
> More people know about "text/calendar" than will know to guess the shortcut name.
