           Summary: Some tests in http/tests/appcache may fail on various
                    ports because of event ordering mismatch.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: dimich at chromium.org

A few tests in this folder set handlers for various appcache events (liek
onerror or onnoupdate) and then use logging from the event handlers to verify
that the events fire (or not fire) appropriately. At the same time, the common
way to terminate those tests is to listen for "message" event from an iframe
that is inserted into the tree.

As noted in bug 35943 and bug 32047, the spec explicitly permits variance in
event order between separate 'event sources'. It would be great to review tests
to make sure they do not hardcode an assumption about order of async events.
Some of those tests are disabled for Chromium port for example, because it uses
different implementation of async cache checks which causes a different (or
even variable) ordering of events.
