UuidInterface generates deprecated message with PHP 8.1

[jokaorgua]

UuidInterface generates deprecated messasge when using in PHP 8.1

Description

Current UuidInterface implementation is

interface UuidInterface extends
    DeprecatedUuidInterface,
    JsonSerializable,
    Serializable

and it generates deprecation message

Mock_UuidInterface_e896a8df implements the Serializable interface, which is deprecated. Implement __serialize() and __unserialize() instead (or in addition, if support for old PHP versions is necessary)

Steps to reproduce

Mock an UuidInterface with phpunit mock

$this->getMockBuilder(UuidInterface::class)->disableOriginalConstructor()->getMock();

Expected behavior

No deprecation message

Environment details

php: 8.1.1 OS: Linux Arch: Arm

[jokaorgua]

possible fix

Add to UuidInterface

    public function __serialize(): array;

    public function __unserialize(array $data): void;

This will require a major version bump, since it's a change to an interface. 😕

[jokaorgua]

@ramsey maybe this ticket should be closed and new one should be opened with 'Php 8.1 compatibility' subject?

[ramsey]

I'm not following. Why does this need a new ticket?

[jokaorgua]

Seems to me a lot of things will be changed to be compatible with PHP 8.1. Not only interface fixing but also the phpdocs for phpstan.  That’s why I’ve suggested a new ticket.

Of course everything could be done in this ticket :)

Hi @ramsey

Wouldn't using #[\ReturnTypeWillChange] suffice in this case?

Edit: nevermind, initially I assumed it was because the return types, I see now is tied to the Serializable interface.

[ramsey]

The request is to add it to UuidInterface. Any change to the interface requires a major version bump.

#[\ReturnTypeWillChange] won't fix deprecation warnings for Serializable, which is an interface that's going away.

[andrew-demb]

@jokaorgua probably this can be fixed only in PHPUnit (which generates mock implementation without __serialize/__unserialize methods)

Introducing new methods to the interface would be the wrong choice.

[ramsey]

I'm going to close this issue, since I don't think there's anything that can be done about it in version 4.x of ramsey/uuid.

I've found a convenient way to make UuidInterface mockable for PHP 8.1. You can override the original UuidInterface by yours via composer. Just add these two lines in your composer.json:

"autoload-dev": {
    "psr-4": {
        <...>
    },
    "exclude-from-classmap": ["vendor/ramsey/uuid/src/UuidInterface.php"],
    "files": ["src/overrides/ramsey/uuid/UuidInterface.php"]
}

Then copy the original UuidInterface into src/overrides/ramsey/uuid/UuidInterface.php file and append Serializable interface methods:

public function __serialize(): array;

public function __unserialize(array $data): void;

Do not forget to call composer dump-autoload at the end.

My stance on this matter is that there is no need to mock a UUID. If you need the UUID to have a fixed value, you can create one using Uuid::fromString() to pass to your SUT. If your SUT generates the UUID inside the unit, you shouldn't need to replace it with a mock. Instead, in whatever value your SUT returns, you can assert the UUID property/method/etc. has an instance of Ramsey\Uuid\UuidInterface. That should be enough to validate the behavior.

[acelot]

@ramsey Agree with you. Unfortunately, I need to do this override, because my project have too many (thousands) test-cases that uses mocked UuidInterface :(

[enumag]

Can't you just bulk replace $this->getMockBuilder(UuidInterface::class)->disableOriginalConstructor()->getMock() with Uuid::random() or something?

[acelot]

Sure, it's possible. But first you need to set up a rule so that other developers do not write in the old way.

P.S. Random values in test-cases? )))
