[Marijn Kruisselbrink, 2016/06/28 18:58:31]

that would be platform/heap/Persistent.h?

[palakj1, 2016/06/29 23:02:41]

Done.

+#include "public/platform/WebPrivatePtr.h"

[Marijn Kruisselbrink, 2016/06/28 18:58:31]

I don't think you're using this header?

[palakj1, 2016/06/29 23:02:41]

Removed.

+#include "public/platform/modules/indexeddb/WebIDBObserver.h"
+#include <memory>

[Marijn Kruisselbrink, 2016/06/28 18:58:31]

I don't think you're using this header either?

[palakj1, 2016/06/29 23:02:41]

Removed.
