Bug 1207245 - part 3 - switch all uses of mozilla::RefPtr<T> to nsRefPtr<T>; r=ehsan This commit was generated using the following script, executed at the top level of a typical source code checkout. # Don't modify select files in mfbt/ because it's not worth trying to # tease out the dependencies currently. # # Don't modify anything in media/gmp-clearkey/0.1/ because those files # use their own RefPtr, defined in their own RefCounted.h. find . -name '*.cpp' -o -name '*.h' -o -name '*.mm' -o -name '*.idl'| \ grep -v 'mfbt/RefPtr.h' | \ grep -v 'mfbt/nsRefPtr.h' | \ grep -v 'mfbt/RefCounted.h' | \ grep -v 'media/gmp-clearkey/0.1/' | \ xargs perl -p -i -e ' s/mozilla::RefPtr/nsRefPtr/g; # handle declarations in headers s/\bRefPtr</nsRefPtr</g; # handle local variables in functions s#mozilla/RefPtr.h#mozilla/nsRefPtr.h#; # handle #includes s#mfbt/RefPtr.h#mfbt/nsRefPtr.h#; # handle strange #includes ' # |using mozilla::RefPtr;| is OK; |using nsRefPtr;| is invalid syntax. find . -name '*.cpp' -o -name '*.mm' | xargs sed -i -e '/using nsRefPtr/d' # RefPtr.h used |byRef| for dealing with COM-style outparams. # nsRefPtr.h uses |getter_AddRefs|. # Fixup that mismatch. find . -name '*.cpp' | \ xargs perl -p -i -e 's/byRef/getter_AddRefs/g'
