TODOs

随着我们合并，积累了债务。如果有一些边缘不起作用，我们希望避免失去对它们的跟踪，同时尽可能解锁。

• KEP-4222: Add CBOR Serializer implementation. #122881留下债务
• IntDecConvertSignedOrFail溢出时的错误，JSON会尝试回退到float64。3月6日2024年api-machinery双周讨论过，决定继续为这种情况返回错误，而不是模仿JSON的回退到float64。
• UnstructuredList SetUnstructuredContent的实现与unstructuredJSONScheme不完全相同：KEP-4222: Decode CBOR to UnstructuredList as UnstructuredJSONScheme does. #124775
• 应该支持Inf/-Inf/NaN吗？当前Protobuf会编码这个，但JSON会产生错误
• 3月6日2024年api-machinery双周讨论过：在这里匹配JSON的行为，编码和解码时出错：KEP-4222: Reject NaN or infinite floating-point values in the CBOR serializer. #125423
• DecOptions没有正确设置DefaultMapType,再次在这里设置它，直到修复被采用为止
• 缺少演示列表编码/解码的测试用例。可能已经在上面涵盖了，但仅此一提：KEP-4222: Decode CBOR to UnstructuredList as UnstructuredJSONScheme does. #124775
• 使用自定义json Marshaler/Unmarshaler实现处理带类型的CR客户端：KEP-4222: Check for and reject unsupported custom marshalers and unmarshalers. #125748
• 为特定类型添加处理数值强制转换为特定类型的Unstructured字段访问器，例如“NestedNumberAsFloat”
• CEL成本估算序列化假设
• 解码单元测试验证“自述CBOR”标签在不改变结果的情况下被接受：KEP-4222: Add CBOR decoder unit test that accepts tag 55799. #124799
• Go字节数组编组为CBOR整数数组，而不是字节字符串：KEP-4222: Encode byte array to CBOR as array of integer, not byte string. #125418
• encoding.BinaryMarshaler或encoding.BinaryUnmarshaler的实现在编码或解码期间未被使用：KEP-4222: Disable recognition of Binary(Unm|M)arshaler in CBOR serializer. #125422
• Decode分配模糊目标应覆盖除unstructured之外的目标go类型
• 为Kubernetes组件添加beta要求，以便自动将RawExtension和FieldsV1从JSON转码为其他格式：KEP-4222: Add transcoding opt-out as beta criteria. enhancements#4758
