As reference for myself and others
Note that the C errno value may be non-zero, and thus the err result may be non-nil, even if the function call is successful. Unlike normal Go conventions, you should first check whether the call succeeded before checking the error result. For example:
So this seems correct here overall.
| defer func() { d.err = nil }() | ||
| return total, d.err |

Maybe it is just me and I know this is pre existing. But it is not obvious to me that this does work and return the error and at the same time set it to nil for *Data. I had to write a small test to confirm https://go.dev/play/p/9uC2vjLa_NU
Maybe it would be easier on reader to turn this into
err := d.err
d.err =nil
return total, err

I’d slightly prefer the non-defer version as well, but I’ll let the package maintainer decide.

Short writes are a valid outcome of gpgme_data_write, but invalid for io.Writer. Loop to conform to the interface. Signed-off-by: Miloslav Trmač <mitr@redhat.com>

Thanks @mtrmac - I don't think changing the defer is enough to warrant another round. So I'll merge as-is. |
