            Bug ID: 141923
           Summary: WTF::WeakPtr should have a "forget" method
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bfulgham at webkit.org

Sometimes we need to be able to clear a WeakPtr. Currently, you do so using the default constructor:

    m_aWeakPointerToSomething = WeakPtr<Something>();

It would be nicer to be able to write:

    m_aWeakPointerToSomething.forget();

With the expectation that the WeakPtr would be 'null' after calling 'forget'.

It should reduce the weak pointer reference count by one on the object being pointed to.
