           Summary: Reduce JSC API static value setter/getter overhead
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: max.hong.shen at gmail.com


To set/get the static value, JSC APIs always call OpaqueJSString::create() to make a thread-safe string copy and pass it to the setXXX/getXXX function which is implemented by the API client. However, the client's setXXX/getXXX doesn't need to know the property name in most case (because they already know the property name). To reduce the overhead, it would be nice to introduce a new JSPropertyAttribute to allow the client decide whether a property name string copy should be created and passed as a parameter.
