This conversion was done with the script: find . -name '*.cpp' -o -name '*.h' -o -name '*.mm' -o -name '*.idl' | \ egrep -v 'cairo-win32-refptr.h|RefPtr.h|TestRefPtr.cpp' | \ xargs sed -i -e 's/mozilla::TemporaryRef</already_AddRefed</g' \ -e 's/TemporaryRef</already_AddRefed</g' Manual fixups were performed in the following instances: - We handled mfbt/RefPtr.h manually so as to not convert TemporaryRef itself into already_AddRefed. - The following files had explicit Move() calls added to make up for the lack of a copy constructor on already_AddRefed: dom/base/ImageEncoder.cpp dom/media/MediaTaskQueue.{h,cpp} dom/media/webaudio/PannerNode.cpp - A redundant overload for MediaTaskQueue::Dispatch was deleted. - A few manual fixups were required in mfbt/tests/TestRefPtr.cpp. - Comments, using declarations, and forward declarations relating to TemporaryRef in dom/canvas/ and gfx/layers/ were changed to refer to already_AddRefed.
