Yesterday I argued in a different thread that it would be better to include the enum name in the error message, since that's useful information for developers whereas users 1) should never see this kind of error to begin with and 2) when they do, their only course of action is reporting the issue anyway.
How about we standard it via a special API
virReportErrorEnumRange(virDomainControllerModelUSB, val->type);
and map this through to a VIR_ERR_ENUM_RANGE error code, with a fixed string format.
"Value '%d' out of range for enum %s"
Sounds like a good idea! We could even add something like This is a bug in libvirt, please report it. or similar to make it clear that the user is not at fault. Not sure about using a separate error code rather than the existing INTERNAL_ERROR, though: it seems like it would not really buy us anything. -- Andrea Bolognani / Red Hat / Virtualization
