Bug: 5156144 Input channels could leak or simply live longer than they should in some cases. 1. Monitor channels (used by the pointer location overlay) are never unregistered, so they would leak. Added code to handle failures in the receive callback by closing the input channel. 2. The DragState held onto its input window and application handles even after the input channel was disposed. Added code to null these handles out when they are no longer needed. 3. Input channels previously used as input event targets would stick around until the targets were cleared (usually on the next event). Added code to detect when the input dispatcher is in an idle state and to proactively clear the targets then to ensure that resources are released promptly. 4. Native input window handles held onto the input channel even after the input window was removed from the input dispatcher. Consequently, the input channel would not be disposed until the input window handle itself was freed. Since the input window handle is held from managed code, this meant that the window's input channel could stick around until the next GC. Refactored the input window handle to separate the properties (info) and identify (handle) state into different objects. Then modified the dispatcher to release the properties (info) when no longer needed, including the input channel. 7. The pointer location overlay does not actually use its standard input channel, only the monitor input channel. Added INPUT_FEATURE_NO_INPUT_CHANNEL to allow windows to request that they not be provided with an input channel at all. Improved some of the error handling logic to emit the status code as part of the exception message. Change-Id: I01988d4391a70c6678c8b0e936ca051af680b1a5
