           Summary: Add an ability to add crash test expectations based on
                    stack trace
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Enhancement
          Priority: P3
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: rniwa at webkit.org


We’ve had many flaky crashes and assertion failures where they could happen on any test yet share the same cause. In such a case, adding [ Crash Pass ] test expectation to all tests is not a good idea because we want to detect crashes of other kinds on those tests especially when the said crash or assertion failure could happen on any test.

Proposal: We could ignore a crash or an assertion failure based on its stack trace (i.e. signature). It’ll allow us to ignore a particular type of crash without jeopardizing our ability to detect other more reproducible crashes.
