file-error-reproducer

Purpose and setup

api/ contains two sub-packages, v1alpha1 and v1alpha2, containing the Foo struct type and its children. Type-wise these packages are the same except for package name. Organization-wise v1alpha2's FooSpec and child types are in a separate file from the main types.go file.

api/
├── v1alpha1
│   └── types.go # Contains all types
└── v1alpha2
    ├── spec.go  # Contains FooSpec and SomeType
    └── types.go # Contains Foo and FooStatus

Results

Environment:

$ go version
go version go1.15.2 linux/amd64

Running go run main.go will output the following:

root github.com/example/file-error-reproducer/api/v1alpha1
	adding ident "github.com/example/file-error-reproducer/api/v1alpha1".Foo
	adding ident "github.com/example/file-error-reproducer/api/v1alpha1".FooStatus
	adding ident "github.com/example/file-error-reproducer/api/v1alpha1".FooSpec
	adding ident "github.com/example/file-error-reproducer/api/v1alpha1".SomeType
root github.com/example/file-error-reproducer/api/v1alpha2
	adding ident "github.com/example/file-error-reproducer/api/v1alpha2".FooSpec
	adding ident "github.com/example/file-error-reproducer/api/v1alpha2".SomeType
	adding ident "github.com/example/file-error-reproducer/api/v1alpha2".Foo
	adding ident "github.com/example/file-error-reproducer/api/v1alpha2".FooStatus

github.com/example/file-error-reproducer/api/v1alpha1.Foo
	field: Spec
		found type info: FooSpec
			adding next field: Type
	field: Status
		found type info: FooStatus
			adding next field: Size
	field: Type
		found type info: SomeType
			adding next field: SomeField
	field: Size
	field: SomeField

github.com/example/file-error-reproducer/api/v1alpha2.Foo
	field: Spec
	field: Status
		found type info: FooStatus
			adding next field: Size
	field: Size

The above says that the v1alpha2 package was parsed differently than v1alpha1, since ast.Inspect on each Foo type cannot find the types for fields of FooSpec.
