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.

/**

* An Image wrapper that disables animation, freezing the image at its first
|
|
* frame. It does this using two strategies. If this is the only instance of the
|
|
* image, animation will never start, because IncrementAnimationConsumers is
|
|
* ignored. If there is another instance that is animated, that's still OK,
|
|
* because any imgIContainer method that is affected by animation gets its
|
|
* aWhichFrame argument set to FRAME_FIRST when it passes through FrozenImage.
|
|
*
|
|
* XXX(seth): There a known (performance, not correctness) issue with
|
|
* GetImageContainer. See the comments for that method for more information.
