           Summary: IndexedDB: Implement spec behavior for multiEntry
                    indexes with invalid/duplicate subkeys
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jsbell at chromium.org


The spec details the handling of multiEntry key paths where the key path yields an array and the array includes values that are duplicates or invalid sub-keys. WebKit's implementation (WebCore/binding/v8/IDBBindingUtilities.cpp) yields an overall InvalidType key if any of the subkeys are invalid.

7.4 If index's multiEntry flag is true, and index key is an Array, remove any elements from index key that are not valid keys and remove any duplicate elements from index key such that only one instance of the duplicate value remains.

For example, the following value of index key [10, 20, null, 30, 20] is converted to [10, 20, 30].
