Function propagateRemoteRefs

pkg/codegen/merge_schemas.go:181–224

propagateRemoteRefs rewrites local "#/..." refs within a schema to be qualified with the remote component path. This is needed so that when an external schema is flattened via allOf, nested type references (array items, additionalProperties, sub-object properties) retain their external qualification

(remoteComponent string, schema *openapi3.Schema)

// additionalProperties, sub-object properties) retain their external
// qualification. See https://github.com/oapi-codegen/oapi-codegen/issues/2288
