Changelog

All notable changes to this project will be documented in this file, in reverse chronological order by release.

3.3.2 - 2018-01-29

Added

  • Nothing.

Changed

  • Nothing.

Deprecated

  • Nothing.

Removed

  • Nothing.

Fixed

  • #243 provides a fix to the ReflectionBasedAbstractFactory to resolve type-hinted arguments with default values to their default values if no matching type is found in the container.

  • #233 fixes a number of parameter annotations to reflect the actual types used.

3.3.1 - 2017-11-27

Added

  • #201 and #202 add support for PHP versions 7.1 and 7.2.

Deprecated

  • Nothing.

Removed

  • Nothing.

Fixed

  • #206 fixes an issue where by callables in Class::method notation were not being honored under PHP 5.6.

3.3.0 - 2017-03-01

Added

  • #180 adds explicit support for PSR-11 (ContainerInterface) by requiring container-interop at a minimum version of 1.2.0, and adding a requirement on psr/container 1.0. Zend\ServiceManager\ServiceLocatorInterface now explicitly extends the ContainerInterface from both projects.

    Factory interfaces still typehint against the container-interop variant, as changing the typehint would break backwards compatibility. Users can duck-type most of these interfaces, however, by creating callables or invokables that typehint against psr/container instead.

Deprecated

  • Nothing.

Removed

  • Nothing.

Fixed

  • Nothing.

3.2.1 - 2017-02-15

Added

  • #176 adds the options -i or --ignore-unresolved to the shipped generate-deps-for-config-factory command. This flag allows it to build configuration for classes resolved by the ConfigAbstractFactory that typehint on interfaces, which was previously unsupported.

Deprecated

  • Nothing.

Removed

  • Nothing.

Fixed

  • #174 updates the ConfigAbstractFactory to allow the config service to be either an array or an ArrayObject; previously, only array was supported.

3.2.0 - 2016-12-19

Added

  • #146 adds Zend\ServiceManager\AbstractFactory\ConfigAbstractFactory, which enables a configuration-based approach to providing class dependencies when all dependencies are services known to the ServiceManager. Please see the documentation for details.
  • #154 adds Zend\ServiceManager\Tool\ConfigDumper, which will introspect a given class to determine dependencies, and then create configuration for Zend\ServiceManager\AbstractFactory\ConfigAbstractFactory, merging it with the provided configuration file. It also adds a vendor binary, generate-deps-for-config-factory, for generating these from the command line.
  • #154 adds Zend\ServiceManager\Tool\FactoryCreator, which will introspect a given class and generate a factory for it. It also adds a vendor binary, generate-factory-for-class, for generating these from the command line.
  • #153 adds Zend\ServiceManager\AbstractFactory\ReflectionBasedAbstractFactory. This class may be used as either a mapped factory or an abstract factory, and will use reflection in order to determine which dependencies to use from the container when instantiating the requested service, with the following rules:
    • Scalar values are not allowed, unless they have default values associated.
    • Values named $config type-hinted against array will be injected with the config service, if present.
    • All other array values will be provided an empty array.
    • Class/interface typehints will be pulled from the container.
  • #150 adds a "cookbook" section to the documentation, with an initial document detailing the pros and cons of abstract factory usage.

Deprecated

  • Nothing.

Removed

  • Nothing.

Fixed

  • #106 adds detection of multiple attempts to register the same instance or named abstract factory, using a previous instance when detected. You may still use multiple discrete instances, however.

3.1.2 - 2016-12-19

Added

  • Nothing.

Deprecated

  • Nothing.

Removed

  • Nothing.

Fixed

  • #167 fixes how exception codes are provided to ServiceNotCreatedException. Previously, the code was provided as-is. However, some PHP internal exception classes, notably PDOException, can sometimes return other values (such as strings), which can lead to fatal errors when instantiating the new exception. The patch provided casts exception codes to integers to prevent these errors.

3.1.1 - 2016-07-15

Added

  • Nothing.

Deprecated

  • Nothing.

Removed

  • Nothing.

Fixed

  • #136 removes several imports to classes in subnamespaces within the ServiceManager classfile, removing potential name resolution conflicts that occurred in edge cases when testing.

3.1.0 - 2016-06-01

Added

  • #103 Allowing installation of ocramius/proxy-manager ^2.0 together with zendframework/zend-servicemanager.
  • #103 Disallowing test failures when running tests against PHP 7.0.*.
  • #113 Improved performance when dealing with registering aliases and factories via ServiceManager#setFactory() and ServiceManager#setAlias()
  • #120 The zendframework/zend-servicemanager component now provides a container-interop/container-interop-implementation implementation

Deprecated

Deprecated

  • Nothing.

Removed

  • Nothing.

Fixed

  • Nothing.

3.0.3 - 2016-02-02

Added

  • #89 adds cyclic alias detection to the ServiceManager; it now raises a Zend\ServiceManager\Exception\CyclicAliasException when one is detected, detailing the cycle detected.
  • #95 adds GitHub Pages publication automation, and moves the documentation to https://zendframework.github.io/zend-servicemanager/
  • #93 adds Zend\ServiceManager\Test\CommonPluginManagerTrait, which can be used to validate that a plugin manager instance is ready for version 3.

Deprecated

  • Nothing.

Removed

  • Nothing.

Fixed

  • #90 fixes several examples in the configuration chapter of the documentation, ensuring that the signatures are correct.
  • #92 ensures that alias resolution is skipped during configuration if no aliases are present, and forward-ports the test from #81 to validate v2/v3 compatibility for plugin managers.

3.0.2 - 2016-01-24

Added

  • #64 performance optimizations when dealing with alias resolution during service manager instantiation

Deprecated

  • Nothing.

Removed

Fixed

  • Nothing.

3.0.0 - 2016-01-11

First stable release of version 3 of zend-servicemanager.

Documentation is now available at http://zend-servicemanager.rtfd.org

Added

  • You can now map multiple key names to the same factory. It was previously possible in ZF2 but it was not enforced by the FactoryInterface interface. Now the interface receives the $requestedName as the second parameter (previously, it was the third).

    Example:

    $sm = new \Zend\ServiceManager\ServiceManager([
        'factories'  => [
            MyClassA::class => MyFactory::class,
            MyClassB::class => MyFactory::class,
            'MyClassC'      => 'MyFactory' // This is equivalent as using ::class
        ],
    ]);
    
    $sm->get(MyClassA::class); // MyFactory will receive MyClassA::class as second parameter
  • Writing a plugin manager has been simplified. If you have simple needs, you no longer need to implement the complete validate method.

    In versions 2.x, if your plugin manager only allows creating instances that implement Zend\Validator\ValidatorInterface, you needed to write the following code:

    class MyPluginManager extends AbstractPluginManager
    {
      public function validate($instance)
      {
          if ($instance instanceof \Zend\Validator\ValidatorInterface) {
              return;
          }
      
          throw new InvalidServiceException(sprintf(
              'Plugin manager "%s" expected an instance of type "%s", but "%s" was received',
               __CLASS__,
               \Zend\Validator\ValidatorInterface::class,
               is_object($instance) ? get_class($instance) : gettype($instance)
          ));
      }
    }

    In version 3, this becomes:

    use Zend\ServiceManager\AbstractPluginManager;
    use Zend\Validator\ValidatorInterface;
    
    class MyPluginManager extends AbstractPluginManager
    {
        protected $instanceOf = ValidatorInterface::class;
    }

    Of course, you can still override the validate method if your logic is more complex.

    To aid migration, validate() will check for a validatePlugin() method (which was required in v2), and proxy to it if found, after emitting an E_USER_DEPRECATED notice prompting you to rename the method.

  • A new method, configure(), was added, allowing full configuration of the ServiceManager instance at once. Each of the various configuration methods — setAlias(), setInvokableClass(), etc. — now proxy to this method.

  • A new method, mapLazyService($name, $class = null), was added, to allow mapping a lazy service, and as an analog to the other various service definition methods.

Deprecated

  • Nothing

Removed

  • Peering has been removed. It was a complex and rarely used feature that was misunderstood most of the time.

  • Integration with Zend\Di has been removed. It may be re-integrated later.

  • MutableCreationOptionsInterface has been removed, as options can now be passed directly through factories.

  • ServiceLocatorAwareInterface and its associated trait has been removed. It was an anti-pattern, and you are encouraged to inject your dependencies in factories instead of injecting the whole service locator.

Changed/Fixed

v3 of the ServiceManager component is a completely rewritten, more efficient implementation of the service locator pattern. It includes a number of breaking changes, outlined in this section.

  • You no longer need a Zend\ServiceManager\Config object to configure the service manager; you can pass the configuration array directly instead.

    In version 2.x:

    $config = new \Zend\ServiceManager\Config([
        'factories'  => [...]
    ]);
    
    $sm = new \Zend\ServiceManager\ServiceManager($config);

    In ZF 3.x:

    $sm = new \Zend\ServiceManager\ServiceManager([
        'factories'  => [...]
    ]);

    Config and ConfigInterface still exist, however, but primarily for the purposes of codifying and aggregating configuration to use.

  • ConfigInterface has two important changes:

    • configureServiceManager() now must return the updated service manager instance.
    • A new method, toArray(), was added, to allow pulling the configuration in order to pass to a ServiceManager or plugin manager's constructor or configure() method.
  • Interfaces for FactoryInterface, DelegatorFactoryInterface and AbstractFactoryInterface have changed. All are now directly invokable. This allows a number of performance optimization internally.

    Additionally, all signatures that accepted a "canonical name" argument now remove it.

    Most of the time, rewriting a factory to match the new interface implies replacing the method name by __invoke, and removing the canonical name argument if present.

    For instance, here is a simple version 2.x factory:

    class MyFactory implements FactoryInterface
    {
        function createService(ServiceLocatorInterface $sl)
        {
            // ...
        }
    }

    The equivalent version 3 factory:

    class MyFactory implements FactoryInterface
    {
        function __invoke(ServiceLocatorInterface $sl, $requestedName)
        {
            // ...
        }
    }

    Note another change in the above: factories also receive a second parameter, enforced through the interface, that allows you to easily map multiple service names to the same factory.

    To provide forwards compatibility, the original interfaces have been retained, but extend the new interfaces (which are under new namespaces). You can implement the new methods in your existing v2 factories in order to make them forwards compatible with v3.

  • The for AbstractFactoryInterface interface renames the method canCreateServiceWithName() to canCreate(), and merges the $name and $requestedName arguments.

  • Plugin managers will now receive the parent service locator instead of itself in factories. In version 2.x, you needed to call the method getServiceLocator() to retrieve the parent (application) service locator. This was confusing, and not IDE friendly as this method was not enforced through the interface.

    In version 2.x, if a factory was set to a service name defined in a plugin manager:

    class MyFactory implements FactoryInterface
    {
        function createService(ServiceLocatorInterface $sl)
        {
            // $sl is actually a plugin manager
          
            $parentLocator = $sl->getServiceLocator();
          
            // ...
        }
    }

    In version 3:

    class MyFactory implements FactoryInterface
    {
        function __invoke(ServiceLocatorInterface $sl, $requestedName)
        {
            // $sl is already the main, parent service locator. If you need to
            // retrieve the plugin manager again, you can retrieve it through the
            // servicelocator:
            $pluginManager = $sl->get(MyPluginManager::class);
            // ...
        }
    }

    In practice, this should reduce code, as dependencies often come from the main service locator, and not the plugin manager itself.

    To assist in migration, the method getServiceLocator() was added to ServiceManager to ensure that existing factories continue to work; the method emits an E_USER_DEPRECATED message to signal developers to update their factories.

  • PluginManager now enforces the need for the main service locator in its constructor. In v2.x, people often forgot to set the parent locator, which led to bugs in factories trying to fetch dependencies from the parent locator. Additionally, plugin managers now pull dependencies from the parent locator by default; if you need to pull a peer plugin, your factories will now need to pull the corresponding plugin manager first.

    If you omit passing a service locator to the constructor, your plugin manager will continue to work, but will emit a deprecation notice indicatin you should update your initialization code.

  • It's so fast now that your app will fly!

2.7.0 - 2016-01-11

Added

  • #60 adds forward compatibility features for AbstractPluingManager and introduces InvokableFactory to help forward migration to version 3.

Deprecated

  • Nothing.

Removed

  • Nothing.

Fixed

  • #46 updates the exception hierarchy to inherit from the container-interop exceptions. This ensures that all exceptions thrown by the component follow the recommendations of that project.
  • #52 fixes the exception message thrown by ServiceManager::setFactory() to remove references to abstract factories.

2.6.0 - 2015-07-23

Added

Deprecated

  • Nothing.

Removed

  • Nothing.

Fixed

  • #3 properly updates the codebase to PHP 5.5, by taking advantage of the default closure binding ($this in a closure is the invoking object when created within a method). It also removes several @requires PHP 5.4.0 annotations.
