Encode Decode map[string]interface{} type

[Gohan]

since this library support map[string]interface{} type, I tried to use it for pacakge struct, what I find is that decode/encode data dismatch, my test code:

func TestCodec(t *testing.T) {
    var (
        mh  codec.MsgpackHandle
        rw  bytes.Buffer
    )
    mh.MapType = reflect.TypeOf(map[string]interface{}(nil))
    enc := codec.NewEncoder(&rw, &mh)

    item := make(map[string]interface{})
    item["key"] = int32(123)
    item["key2"] = "string"

    err := enc.Encode(&item)
    if err == nil {
        t.Log("Encode OK", "type", reflect.TypeOf(item["key"]), reflect.TypeOf(item["key2"]))
    }

    var item_decoded map[string]interface{}

    dec := codec.NewDecoder(&rw, &mh)
    err = dec.Decode(&item_decoded)
    if err == nil {
        t.Log("Decode OK", "type", reflect.TypeOf(item_decoded["key"]), reflect.TypeOf(item_decoded["key2"]))
    }
}

the result:

proto_test.go:63: Encode OK type int32 string
proto_test.go:71: Decode OK type int64 []uint8

update:

I change the handle config mh.RawToString = true, now the int type still not match:

proto_test.go:64: Encode OK type int32 string
proto_test.go:72: Decode OK type int64 string

msgpack spec include int8 int16 int32 many int families, this result make me confuse.

It is my fault that I misunderstanding the encode decode process, msgpack don't distinguish source type is either int32 or int64. I'll close this issue
