841843 - URL function not available in worker context

Status: RESOLVED DUPLICATE of bug 813253

(Core :: DOM: Workers, defect)

Description

[aviynw]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.70 Safari/537.17

Steps to reproduce:

Launched a dedicated web worker.  Tried to access self.URL


Actual results:

got error that URL is not defined


Expected results:

I should have been able to access the equivalent function that is window.URL in the main thread.  The reason I want access to this function is because I'm launching workers and subworkers that are created with inline text.  To accomplish this I need access to URL.createObjectURL.  my code roughly looks as follows

var blob = new Blob(["onmessage = function(e) { postMessage('msg from worker'); }"]);
var blobURL = self.URL.createObjectURL(blob);
var worker = new Worker(blobURL);

In chrome, workers have access to this URL function (though chrome doesn't support creating subworkers).  Is there a reason firefox chose not to include this feature

Other than it requiring extra work to port things to workers and no one having done that work yet?  Unclear.  Ben?

This should be a dup of bug 813253, which just landed.
