1038855 - SharedMemoryBasic fields should use nsRefPtr

Status: RESOLVED FIXED

(Core :: IPC, defect)

Description

[Andrew McCreight [:mccr8] (PTO until 12-2)]

SharedMemoryBasic inherits from SharedMemory, which is a refcounted class.  CrossProcessMutex, CompositorChild::SharedFrameMetricsData and AsyncPanZoomController fail to do this.

Attachment: part 1 - Use an nsRefPtr for AsyncPanZoomController::mSharedFrameMetricsBuffer.

This is all straightforward.

Comment 2

[Andrew McCreight [:mccr8] (PTO until 12-2)]

Attachment: part 2 - Use an nsRefPtr for CompositorChild::SharedFrameMetricsData::mBuffer.

Comment 3

[Andrew McCreight [:mccr8] (PTO until 12-2)]

Attachment: part 3 - Use an nsRefPtr for CrossProcessMutex::mSharedBuffer.

hmm I'll ditch the |mBuffer = nullptr;| in the second patch...
