title: Changelog

This is a list of changes/improvements that were introduced in ProxyManager

2.0.4

Fixed

• Remove deprecated getMock usage from tests #325
• Fix incorrect type in docs example #329
• Bug when proxy __get magic method #344
• Fix lazy loading value holder magic method support #345

2.0.3

Fixed

• Various test suite cleanups, mostly because of new PHPUnit 5.4.0 deprecations being introduced #318
• Removed zendframework/zend-code:3.0.3 from installable dependencies, since a critical bug was introduced in it #321 #323 #324. Please upgrade to zendframework/zend-code:3.0.4 or newer.

2.0.2

Fixed

• Various optimizations were performed in the ocramius/package-versions integration in order to prevent "class not found" fatals. #294
• Null objects produced via a given class name were not extending from the given class name, causing obvious LSP compliance and type-compatibility issues. #300 #301
• Specific installation versions were removed from the README.md install instructions, since composer is installing the latest available version by default. #305
• PHP 7.0.6 support was dropped. PHP 7.0.6 includes some nasty reflection bugs that caused __isset to be called when ReflectionProperty#getValue() is used (https://bugs.php.net/72174). #306 #308
• PHP 7.0.7 contains additional limitations as to when $this can be used. Specifically, $this cannot be used as a parameter name for closures that have an already assigned $this. Due to $this being incorrectly used as parameter name within this library, running ProxyManager on PHP 7.0.7 would have caused a fatal error. #306 #308 #316
• PHP 7.1.0-DEV includes type-checks for incompatible arithmetic operations: some of those operations were erroneously performed in the library internals. #308

2.0.1

Fixed

• Travis-CI environment was fixed to test the library using the minimum dependencies version.

Added

• Added unit test to make sure that properties skipped should be preserved even being cloned.

2.0.0

BC Breaks

Please refer to the upgrade documentation to see which backwards-incompatible changes were applied to this release.

New features

PHP 7 support

ProxyManager will now correctly operate in PHP 7 environments.

PHP 7 Return type hints

ProxyManager will now correctly mimic signatures of methods with return type hints:

class SayHello
{
    public function hello() : string
    {
        return 'hello!';
    }
}

PHP 7 Scalar type hints

ProxyManager will now correctly mimic signatures of methods with scalar type hints

class SayHello
{
    public function hello(string $name) : string
    {
        return 'hello, ' . $name;
    }
}

PHP 5.6 Variadics support

ProxyManager will now correctly mimic behavior of methods with variadic parameters:

class SayHello
{
    public function hello(string ...$names) : string
    {
        return 'hello, ' . implode(', ', $names);
    }
}

By-ref variadic arguments are also supported:

class SayHello
{
    public function hello(string ... & $names)
    {
        foreach ($names as & $name) {
            $name = 'hello, ' . $name;
        }
    }
}

Constructors in proxies are not replaced anymore

In ProxyManager v1.x, the constructor of a proxy was completely replaced with a method accepting proxy-specific parameters.

This is no longer true, and you will be able to use the constructor of your objects as if the class wasn't proxied at all:

class SayHello
{
    public function __construct()
    {
        echo 'Hello!';
    }
}

/* @var $proxyGenerator \ProxyManager\ProxyGenerator\ProxyGeneratorInterface */
$proxyClass = $proxyGenerator->generateProxy(
    new ReflectionClass(SayHello::class),
    new ClassGenerator('ProxyClassName')
);

eval('<?php ' . $proxyClass->generate());

$proxyName = $proxyClass->getName();
$object = new ProxyClassName(); // echoes "Hello!"

var_dump($object); // a proxy object

If you still want to manually build a proxy (without factories), a public static staticProxyConstructor method is added to the generated proxy classes.

Friend classes support

You can now access state of "friend objects" at any time.

class EmailAddress
{
    private $address;

    public function __construct(string $address)
    {
        assertEmail($address);
        
        $this->address = $address;
    }
    
    public function equalsTo(EmailAddress $other)
    {
        return $this->address === $other->address;
    }
}

When using lazy-loading or access-interceptors, the equalsTo method will properly work, as even protected and private access are now correctly proxied.

Ghost objects now only lazy-load on state-access

Lazy loading ghost objects now trigger lazy-loading only when their state is accessed. This also implies that lazy loading ghost objects cannot be used with interfaces anymore.

class AccessPolicy
{
    private $policyName;
    
    /**
     * Calling this method WILL cause lazy-loading, when using a ghost object,
     * as the method is accessing the object's state
     */
    public function getPolicyName() : string
    {
        return $this->policyName;        
    }
    
    /**
     * Calling this method WILL NOT cause lazy-loading, when using a ghost object,
     * as the method is not reading any from the object.
     */
    public function allowAccess() : bool
    {
        return false;
    }
}

Faster ghost object state initialization

Lazy loading ghost objects can now be initialized in a more efficient way, by avoiding reflection or setters:

class Foo
{
    private $a;
    protected $b;
    public $c;
}

$factory = new \ProxyManager\Factory\LazyLoadingGhostFactory();

$proxy = $factory-createProxy(
    Foo::class,
    function (
        GhostObjectInterface $proxy, 
        string $method, 
        array $parameters, 
        & $initializer,
        array $properties
    ) {
        $initializer   = null;

        $properties["\0Foo\0a"] = 'abc';
        $properties["\0*\0b"]   = 'def';
        $properties['c']        = 'ghi';

        return true;
    }
);


$reflectionA = new ReflectionProperty(Foo::class, 'a');
$reflectionA->setAccessible(true);

var_dump($reflectionA->getValue($proxy)); // dumps "abc"

$reflectionB = new ReflectionProperty(Foo::class, 'b');
$reflectionB->setAccessible(true);

var_dump($reflectionB->getValue($proxy)); // dumps "def"

var_dump($proxy->c); // dumps "ghi"

Skipping lazy-loaded properties in generated proxies

Lazy loading ghost objects can now skip lazy-loading for certain properties. This is especially useful when you have properties that are always available, such as identifiers of entities:

class User
{
    private $id;
    private $username;

    public function getId() : int
    {
        return $this->id;
    }

    public function getUsername() : string
    {
        return $this->username;
    }
}

/* @var $proxy User */
$proxy = (new \ProxyManager\Factory\LazyLoadingGhostFactory())->createProxy(
    User::class,
    function (
        GhostObjectInterface $proxy,
        string $method,
        array $parameters,
        & $initializer,
        array $properties
    ) {
        $initializer   = null;

        var_dump('Triggered lazy-loading!');

        $properties["\0User\0username"] = 'Ocramius';

        return true;
    },
    [
        'skippedProperties' => [
            "\0User\0id",
        ],
    ]
);

$idReflection = new \ReflectionProperty(User::class, 'id');

$idReflection->setAccessible(true);
$idReflection->setValue($proxy, 123);

var_dump($proxy->getId());       // 123
var_dump($proxy->getUsername()); // "Triggered lazy-loading!", then "Ocramius"

Proxies are now always generated on-the-fly by default

Proxies are now automatically generated any time you require them: no configuration needed. If you want to gain better performance, you may still want to read the tuning for production docs.

Proxy names are now hashed, simplified signature is attached to them

Proxy classes now have shorter names, as the parameters used to generate them are hashed into their name. A signature is attached to proxy classes (as a private static property) so that proxy classes aren't re-used across library updates. Upgrading ProxyManager will now cause all proxies to be re-generated automatically, while the old proxy files are going to be ignored.
