This PR changes the default visibility of fields in objects created by
std.mergePatch: previously they were atUnhidevisibility, equivalent to the:::operator, but as of this PR they are now atNormalstandard visibility.Concretely, previously
would return
{a: 1}but after this patch it returns{a:: 1), i.e. it preserves the hidden field.It turns out that v0.20.0 of google/jsonnet and google/go-jsonnet also differ in their behavior here. That, in turn, is due to a behavior difference in the default visibility of fields in object comprehension results: jsonnet marks object comprehension fields as forced-visible, while go-jsonnet marks them as inherited visibility; see google/jsonnet#1111.
jsonnet accepted google/jsonnet#1140 to match go-jsonnet's behavior.
Note that sjsonnet already matches go-jsonnet's behavior for object comprehensions: we only have a difference in
std.mergePatchbecause our current implementation explicitly hardcodes Unhide visibility.This PR changes that mergePatch-specific behavior to match the current go-jsonnet (and future jsonnet) behavior.
