Re: [libvirt] [RFC] Version numbers outside of releases

This is not that attractive from POV the language bindings.   eg in the Go code, I need to make usage of the new APIs conditional at compile time. For example for the new APIs added in 3.4.0 I have code like      func (v *Stream) RecvFlags(p []byte, flags StreamRecvFlagsValues) (int, error) {          if C.LIBVIR_VERSION_NUMBER < 3004000 {                  return 0, GetNotImplementedError("virStreamRecvFlags")          }            n := C.virStreamRecvFlagsCompat(v.ptr, (*C.char)(unsafe.Pointer(&p[0])), C.size_t(len(p)), C.uint(flags))            ...snip...    }   and       int virStreamRecvFlagsCompat(virStreamPtr st,                                 char *data,                                 size_t nbytes,                                 unsigned int flags)    {    #if LIBVIR_VERSION_NUMBER < 3004000        assert(0); // Caller should have checked version    #else        return virStreamRecvFlags(st, data, nbytes, flags);    #endif    }   The suggested versioning scheme would require changing all these version numbers checks to 3003090 is rather unpleasant IMHO.
