Hey @tuaris. Could you please show your type transformer and the messagepack data you try to unpack?
from msgpack.php.

This is the type transformer:
final class MsgpackLiteJsDateTransformer implements \MessagePack\TypeTransformer\Unpackable {
public function getType(): int {
return 5;
}
public function unpack(\MessagePack\BufferUnpacker $unpacker, int $extLength): \DateTimeImmutable {
return \DateTimeImmutable::createFromFormat('U', $unpacker->unpackInt());
}
}The data I'm trying to unpack is generated by this library: https://github.com/tinylib/msgp:
type Event struct {
Timestamp int64 `json:"timestamp" msg:"timestamp"`
Message string `json:"message,omitempty" msg:"message"`
}
func NewEvent() *Event {
return &Event{
Timestamp: time.Now().UnixNano(),
Message: "A message",
}
}from msgpack.php.

Could you provide a full go script or data it generates? (from your example I don't see how you wrap event timestamps into extensions). I tried this (which obviously doesn't utilize msgpack extensions):
package main
import (
"fmt"
"time"
)
//go:generate msgp
type Event struct {
Timestamp int64 `json:"timestamp" msg:"timestamp"`
Message string `json:"message,omitempty" msg:"message"`
}
func NewEvent() *Event {
return &Event{
Timestamp: time.Now().UnixNano(),
Message: "A message",
}
}
func main() {
data, err := NewEvent().MarshalMsg(nil)
if err != nil {
panic(err)
}
fmt.Printf("Event is encoded as %x\n", data)
}which outputs
Event is encoded as 82a974696d657374616d70d3156db5a268337dfba76d657373616765a941206d657373616765
Php script:
$packed = hex2bin('82a974696d657374616d70d3156db5fdd07481c9a76d657373616765a941206d657373616765');
$unpacker = new BufferUnpacker($packed);
var_dump($unpacker->unpack());Output:
array(2) {
'timestamp' =>
int(1544090348986597833)
'message' =>
string(9) "A message"
}
from msgpack.php.
