Nathan Froyd 01583602a9 Bug 1207245 - part 6 - rename nsRefPtr<T> to RefPtr<T>; r=ehsan; a=Tomcat
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

--HG--
rename : mfbt/nsRefPtr.h => mfbt/RefPtr.h

/**
* We would like to expose PushManager and PushSubscription on window and
* workers. Parts of the Push API is implemented in JS out of necessity due to:
* 1) Using frame message managers, in which
* nsIMessageListener::receiveMessage() must be in JS.
* 2) It is easier to use certain APIs like the permission prompt and Promises
* from JS.
*
* Unfortunately, JS-implemented WebIDL is not supported off the main thread. To
* aid in fixing this, the nsIPushClient is introduced which deals with part (1)
* above. Part (2) is handled by PushManagerImpl on the main thread. PushManager
* wraps this in C++ since our bindings code cannot accomodate "JS-implemented
* on the main thread, C++ on the worker" bindings. PushManager simply forwards
* the calls to the JS component.
*
* On the worker threads, we don't have to deal with permission prompts, instead
* we just reject calls if the principal does not have permission. On workers
* WorkerPushManager dispatches runnables to the main thread which directly call
* nsIPushClient.
*
* PushSubscription is in C++ on both threads since it isn't particularly
* verbose to implement in C++ compared to JS.
