646887 - ChromeWorker and "@mozilla.org/xmlextras/domparser;1"

Status: RESOLVED INVALID

Description

[Erik Vold]

Can "@mozilla.org/xmlextras/domparser;1" be made available to ChromeWorkers?

Comment 1

[Boris Zbarsky [:bzbarsky, bz on IRC]]

You can't access DOM nodes from off the main thread.  So the usability of domparser would be pretty darned minimal, no?

Comment 2

[Erik Vold]

So the following is not possible in ChromeWorker:

var doc = Cc["@mozilla.org/xmlextras/domparser;1"].createInstance(Ci.nsIDOMParser).parseFromString("<UserScriptConfig/>", "text/xml");
var ele = doc.createElement("Script");
doc.firstChild.appendChild(ele);

because line 2 & 3 cannot be done off of the main thread?

Comment 3

[Boris Zbarsky [:bzbarsky, bz on IRC]]

The parseFromString in line 1 will almost certainly corrupt memory if done from a background thread.

(Note that |doc| above is a DOM node, by the way.)
