Done.

I think this still has to be in the .cc file to avoid it being duplicated in all
the clients. Does it work if you write that here:

ShareServiceImpl::~ShareServiceImpl() = default;

?

s/mojo::InterfaceRequest<ShareService>/ShareServiceRequest/

Done.

This will leak the ShareServiceImpl. Use StrongBinding instead:

mojo::MakeStrongBinding(base::MakeUnique<ShareServiceImpl>(),
                        std::move(request));

and remove |binding_|.

[constantina, 2016/12/12 02:50:32]

Done.
