Unmarshal loses type information

[philomory]

When unmarshalling a YAML file to a map[string]interface{}, all integer values are converted to float64 values instead, despite the fact that both YAML and Go support integer values. This is presumably due to the way the package goes from YAML to JSON before finally unmarshalling to "real" Go types, with JSON only having float numeric types.

For an example of this problem in action (and a comparison to gopkg.in/yaml.v2, which does not exhibit this issue) see https://play.golang.org/p/YfO69Z3vi-V.

This is particularly notable when Helm is unmarshalling values.yaml. For an example of that, see helm/helm#8978 (comment)

This is still a problem. I just ran into it using sigs.k8s.io/yaml.

Integers are getting unmarshalled as float64 instead of int.

I noticed that this is fixed in gopkg.in/yaml.v3 as well.

For lack of a better owner, can someone from api-machinery look into this? It affects the Unstructured API client mostly.
