Re: [libvirt] [PATCH 3/3] Add sentinel for virErrorNumber enum

I'm worried that you need to split this into some prerequisite patches that change the message contents _and all callers_, before the patch that collapses things into a VIR_ENUM. Using VIR_ERR_INVALID_CONN as an example, libvirt.c:virConnectClose calls: virLibConnError(VIR_ERR_INVALID_CONN, __FUNCTION__) Pre-patch, this results in 'location: custom message': virConnectClose: invalid connection pointer in virConnectClose post-patch, this results in 'locatoin: category: half a custom message': virConnectClose: invalid connection pointer: virConnectClose and we have a bad error message. But if we first clean up all callers of VIR_ERR_INVALID_CONN to pass a useful message, rather than the current status quo of just a function name, _then_ shortening the error string to 'location: category: message' will make more sense.
