Re: [Xen-devel] [PATCH v3 4/8] golang/xenlight: Errors are negative

[Nick Rosbrook <rosbrookn@xxxxxxxxx>]

> Commit 871e51d2d4 changed the sign on the xenlight error types (making
> the values negative, same as the C-generated constants), but failed to
> flip the sign in the Error() string function.  The result is that
> ErrorNonspecific.String() prints "libxl error: 1" rather than the
> human-readable error message.
>
> Get rid of the whole issue by making libxlErrors a map, and mapping
> actual error values to string, falling back to printing the actual
> value of the Error type if it's not present.
