file:read-binary error

Dear friends We updated 2 days ago from 8.2 to 8.4 and are experiencing a few strange things. Aside this : https://github.com/BaseXdb/basex/issues/702#issuecomment-212352923, we discovered that this kind of function doesn't work anymore :

(:~
: resource function for the static files
:
: @param $file file or unknown path
: @return rest response and binary file
:)
declare
%rest:path('/synopsx/files/{$file=.+}')
function synopsx.files:file($file as xs:string) as item()+ {
   let $path := $G:FILES || $file
   return (
     <rest:response>
       <http:response>
         <http:header name='Cache-Control' value='max-age=3600,public'/>
       </http:response>
       <output:serialization-parameters>
       <output:media-type value='{ synopsx.files:mime-type($path) }'/>
       <output:method value='raw'/>
       </output:serialization-parameters>
     </rest:response>,
     file:read-binary($path))
};

Response : HTTP ERROR 400 Problem accessing /synopsx/files/synopsx.js. Reason: Stopped at /resource/basex/webapp/synopsx/_restxq/files.xqm, 38/10: [SEPM0017] Value of 'method' must be one of (xml,xhtml,html,json,csv,text,adaptive,basex). ------------------------------------------------------------------------ /Powered by Jetty:// /where, on my computer, an exact clone of the webapp runing with a 8.3 works perfectly and sends me my js file as expected. I read the changelogs but couldn't figure out what could be involved here. I tried to change "raw" to "adaptive" but then I get a file not found answer : HTTP ERROR 400 Problem accessing /synopsx/files/synopsx.js.

Hi Maud, Sorry for the delay, I’ll soon give you an answer on your other e-mails!

With 8.4, the "raw" output method has become obsolete. Your code should work if you remove the following line:

   <output:method value='raw'/>

Here is yet another solution for the synopsx.files:file() function, which is a bit more compact:

  function synopsx.files:file($file as xs:string) as item()+ {
    let $path := $G:FILES || $file
    return (
      web:response-header(map { 'media-type': web:content-type($path) }),
      file:read-binary($path)
    )
  };

Hope this helps, feel free to ask more questions, Christian
