            Bug ID: 178701
           Summary: [WPE][GTK] Fix the flakiness dashboard
                    ("XMLHttpRequest cannot load URL due to access control
                    checks"
           Product: WebKit
           Version: Other
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
          Assignee: webkit-unassigned at lists.webkit.org

In our layout test results, we have a link to the flakiness dashboard, e.g.:

http://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=imported%2Fw3c%2Fweb-platform-tests%2Fencrypted-media%2Fclearkey-mp4-playback-temporary-clear-encrypted.html

The flakiness dashboard has been a completely white page for as long as I remember. I noticed today that it works fine in Firefox and Chrome, so the fact that it doesn't work is probably a WebKit bug. It's filled with lovely errors like this:

XMLHttpRequest cannot load https://svn.webkit.org/repository/webkit/trunk/LayoutTests/platform/gtk/TestExpectations due to access control checks.
request — loader.js:56
_loadExpectationsFiles — loader.js:236
_loadNext — loader.js:111
_handleResourceLoad — loader.js:205
_handleResultsFileLoadError — loader.js:200
(anonymous function) — loader.js:139
(anonymous function) — dashboard_base.js:148
onreadystatechange — loader.js:53
request — loader.js:56

Cannot load XMLHttpRequest "due to access control checks." I've seen this very generic error result in breakage on many, many other websites, but let's focus on the flakiness dashboard for now. We should debug the code to figure out what's going on. It's probably a soup-specific issue.
