The point of adding it to HACKING is to encourage new code to abide by the standard, and not necessarily to retrofit existing code. And you are correct that existing code doesn't always use enum type-safety compiler guarantees - which makes the enum that much harder to modify later if we ever add enum values. But in some cases, it is fairly obvious that we don't plan to add any enum values, in which case a simple if statement or use of a default label is fine. It's a case-by-case judgment call of what makes the code easier to maintain. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
