What's this case for? Can you just use the SharedMemoryHandle exclusively now?

[bbudge, 2013/06/05 02:05:03]

The difficulty is that the ImageData constructor that takes a SharedMemoryHandle
is only available for NaCl. I could expose it but only for Linux since
ImageHandle and SharedMemoryHandle are the same type on other platforms, so this
would be ambiguous. That's probably the way to go, since this CL isn't passing
for Linux non-NaCl cases. WDYT?

This issue was solved by the recent ImageData refactoring. Done.

       frame->image_data =
-          (new ImageData(image_data, image_desc, fd))->GetReference();
-#elif defined(OS_LINUX) || defined(OS_WIN) || defined(OS_MACOSX)
+          (new ImageData(image_data, image_desc, shmem_key))->GetReference();
+#elif defined(OS_POSIX) || defined(OS_WIN)
       base::SharedMemoryHandle handle;
       if (!reply_params.TakeSharedMemoryHandleAtIndex(0, &handle))
         frame->image_data = 0;
       frame->image_data =
           (new ImageData(image_data, image_desc, handle))->GetReference();
 #else
 #error Not implemented.
 #endif
     }
     get_frame_callback_->Run(result);
   }
 }
