The bulk of this commit was generated with a script, executed at the top level of a typical source code checkout. The only non-machine-generated part was modifying MFBT's moz.build to reflect the new naming. CLOSED TREE makes big refactorings like this a piece of cake. # The main substitution. find . -name '*.cpp' -o -name '*.cc' -o -name '*.h' -o -name '*.mm' -o -name '*.idl'| \ xargs perl -p -i -e ' s/nsRefPtr\.h/RefPtr\.h/g; # handle includes s/nsRefPtr ?</RefPtr</g; # handle declarations and variables ' # Handle a special friend declaration in gfx/layers/AtomicRefCountedWithFinalize.h. perl -p -i -e 's/::nsRefPtr;/::RefPtr;/' gfx/layers/AtomicRefCountedWithFinalize.h # Handle nsRefPtr.h itself, a couple places that define constructors # from nsRefPtr, and code generators specially. We do this here, rather # than indiscriminantly s/nsRefPtr/RefPtr/, because that would rename # things like nsRefPtrHashtable. perl -p -i -e 's/nsRefPtr/RefPtr/g' \ mfbt/nsRefPtr.h \ xpcom/glue/nsCOMPtr.h \ xpcom/base/OwningNonNull.h \ ipc/ipdl/ipdl/lower.py \ ipc/ipdl/ipdl/builtin.py \ dom/bindings/Codegen.py \ python/lldbutils/lldbutils/utils.py # In our indiscriminate substitution above, we renamed # nsRefPtrGetterAddRefs, the class behind getter_AddRefs. Fix that up. find . -name '*.cpp' -o -name '*.h' -o -name '*.idl' | \ xargs perl -p -i -e 's/nsRefPtrGetterAddRefs/RefPtrGetterAddRefs/g' if [ -d .git ]; then git mv mfbt/nsRefPtr.h mfbt/RefPtr.h else hg mv mfbt/nsRefPtr.h mfbt/RefPtr.h fi

/**
|
|
* An implementation of PaintedLayer that ONLY supports remote
|
|
* composition that is backed by tiles. This painted layer implementation
|
|
* is better suited to mobile hardware to work around slow implementation
|
|
* of glTexImage2D (for OGL compositors), and restrait memory bandwidth.
|
|
*
|
|
* Tiled PaintedLayers use a different protocol compared with other
|
|
* layers. A copy of the tiled buffer is made and sent to the compositing
|
|
* thread via the layers protocol. Tiles are uploaded by the buffers
|
|
* asynchonously without using IPC, that means they are not safe for cross-
|
|
* process use (bug 747811). Each tile has a TextureHost/Client pair but
|
|
* they communicate directly rather than using the Texture protocol.
|
|
*
|
|
* There is no ContentClient for tiled layers. There is a ContentHost, however.
