Presumably this is because in the test suite we've not bothered to set the 'id' field to any value. I can't help thinking that virDomainObjGetShortName ought to return a fatal error if 'id' is still -1, as in non-test suite code, this would be indication of a significant screw up by someone trying to create names before the VM config is updated to reflect running state. This would of course mean our tests should set 'id' to a sensible value too. No need to fix for this patch though - just a curiosity to look at a later date Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :| -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
