Serialized UUIDs don't store codec information

[ntzm]

To reproduce:

$factory = new UuidFactory();
$factory->setCodec(new OrderedTimeCodec($factory->getUuidBuilder()));

$a = $factory->uuid1();
$b = unserialize(serialize($a));
var_dump($a->getBytes(), $b->getBytes(), $a->getBytes() === $b->getBytes());

This is correct, and it's been an issue for a long time, though it's never been discussed here. I'm going to mark it as a bug because I'd like to come up with a solution for it.

Additionally, when UUIDs using alternate codecs to shift their bits around are stored as bytes in databases, for example, there's no information stored within them to note that they have been modified and must be decoded using the proper codec.

Hi,
in my Symfony app I upgraded ramsey/uuid form v3.9.6 to v4.7.1 and ramsey/uuid-doctrine from v1.8.1 to v2.0.0.

After that upgrade app has started throwing error on UUID unserialize (when Symfony tries to unserialize session data).

Error:

In OrderedTimeCodec.php line 105:

How to reproduce:

$factory = new UuidFactory();
$factory->setCodec(new OrderedTimeCodec(
    $factory->getUuidBuilder()
));

Uuid::setFactory($factory);
$uuid = Uuid::fromString('211a3b1e-928f-11ed-b52d-0242ac12000b');

$serializedUuid = serialize($uuid);
$unserializedUuid = unserialize($serializedUuid);

I have noticed that issue is somewhat related to OrderedTimeCodec specifically to rearrange of bytes for optimal storage.
If I add this code to Uuid::serialize() then unserialize works OK.

if ($this->codec instanceof OrderedTimeCodec) {
    $bytes = $this->getFields()->getBytes();
    $rearrangedBytes = $bytes[6] . $bytes[7]
        . $bytes[4] . $bytes[5]
        . $bytes[0] . $bytes[1] . $bytes[2] . $bytes[3]
        . substr($bytes, 8);

    return $rearrangedBytes;
}

This rearranges bytes before serialization and on unserialize OrderedTimeCodec will rearrange bytes to original order.

Not sure if this is related to first issue, if not I can open separate issue.
