<h3>Log Message</h3>
<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/181631">r181631</a> - [GTK] WebKitDOM objects leaking
https://bugs.webkit.org/show_bug.cgi?id=118788
Reviewed by Darin Adler and Sergio Villar Senin.
Source/WebCore:
Use a DOMwindowObserver class, derived from DOMWindowProperty to
be notified when the window object is detached from the frame to
clear the DOM objects associated to that frame in that case too.
* bindings/gobject/DOMObjectCache.cpp:
Tools:
Update DOMObjectCache unit test to check that DOM objects are also
released when new contents are loaded in the web view, and the old
document is detached from the frame.
* TestWebKitAPI/Tests/WebKit2Gtk/TestDOMNode.cpp:
(testWebKitDOMObjectCache):
* TestWebKitAPI/Tests/WebKit2Gtk/WebProcessTest.cpp:
(runTest):</pre>
