virDomainGetName() can return NULL, so you'd need to use NULLSTR(name) everywhere. That alone requires a v2, but I'd wait for feedback from danpb or DV as to whether this makes sense. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

virDomainGetName() can return NULL, so you'd need to use NULLSTR(name) everywhere. That alone requires a v2, but I'd wait for feedback from danpb or DV as to whether this makes sense.
Whether what makes sense?
Do we risk any deadlocks by calling a public API (virDomainGetName) from within the body of another public API (such as virDomainGetConnect)? If there is any risk, then the extra debug information is not worth it. But if it's always safe to do, then I like the idea of the extra information, even though it adds a slight amount of time to execute each domain-related API. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

Thanks, sent v2 patch with NULLSTR(name), wait for your feedback there. Regards Osier
