Also:
- Make the methods in `AbstractServiceProvider` protected.
- Add an autoloader for files in the `tests/php/src` directory.
- Fix a bug in the provisional (?) autoloader.
- camelCase methods changed to snake_case for consistency with WP.
- Added a check in `ExtendedContainer::get` that throws an informative
exception if a non-namespaced class name is passed.
- `container->reset_resolved()` is called during unit testing bootstrap.
- Added some utility methods in `WC_Unit_Test_Case`.
- Added a new class `ExtendedContainer` that extends League's container.
- `add` modified to reject classes not in the root Woo namespace.
- Has two new methods, `replace` and `reset_resolved`.
- It's used as the underlying container instead of League's one
in `Container`, but the new methods are not exposed.
- At unit test bootstrap time the globally registered container is
replaced with the extended one that `Container` stores
(grabbed from private property using reflection).
- A new `MockableLegacyProxy` is added. It inherits from `LegacyProxy`
and allows to mock functions, static methods and legacy classes.
- The registeed `LegacyProxy` is replaced with the mockable version
during unit test bootstrap.
- A PHPUnit hook is added to reset the mockable proxy to its initial
state (so that nothing is mocked) before each test.
- `WC_Unit_Test_Case` gets helper methods to mock functions, static
methods and classes without having to retrieve the proxy class.
- `wc_get_container` declares a return type now.
- The autoloader now runs before `autoload_packages.php` is included.
- The autloader now excludes the namespaces for Admin, Blocs, Rest API.
- `private $container` in `Container` is now declared as being
of type `\League\Container\Container`.
- The underlying container is registered with `share` instead of `add`.
- All methods in `AbstractServiceProvider` now allow passing a concrete.
- `AbstractServiceProvider::addWithAutoArguments` now checks if an
argument has a default value, and registers the argument so that
that value is supplied when constructing the object.
- `Proxies` class renamed to `ProxiesServiceProvider`.
- The methods to call code in `LegacyProxy` now use `call_user_func_array`.
- The `Container` class now implements `Psr\Container\ContainerInterface`
(and registers itself as such), holding a private instance of the
real container. This way it's a read-only container from the point
of view of plugins (which should use their own containers, but
can still use this to get WooCommerce classes).
- All registrations are now done in the `Container` constructor via
service providers.
- The container instance is now held in a global variable, set in
`woocommerce.php`
- Added the `wc_get_container` function for old code.
- Added the `AbstractServiceProvider` class, which inherits with the
corresponding League's class and adds some utility methods,
most notably `add/shareWithAutoArguments`.
- Added the `ActionsProxy` and `LegacyProxy` classes, they are
registered via a dedicated service provider.
- `WC_Queue_Interface` is no longer resolvable via the container
(which is for classes inside `src` only).
- All the method names in the new classes have the format `fooBarFizz`
to be PSR4 compliant, so the MethodNameInvalid error has been
disabled in phpcs.xml for the `src` directory.
- Introduced the `@public` annotation for public API classes
(classes that plugins can use and whose backwards compatibility
we guarantee), applied to `ActionsProxy` and to `LegacyProxy` for now.
- Removed the hack for the autoloader as now it doesn't work anyway.
For the changes in this branch to work, now WP_DEBUG must be false.
- Renamed from `ObjectContainer` to `Container`.
- It now inherits from PHP League's `Container`.
- It has now a `defineAsSharedAutowired` method.
- Initialization moved to the `WooCommerce::init_container` method.
- The static method for object resolution is now `WooCommerce::get_instance_of`.
- Add PHP League's Container package via Composer.
- Add an ObjectContainer class that encapsulates all the configuration
and insulates the codebase from the concrete DI engine used.
- Add an improved ReflectionContainer class that will allow to
register individual classes as singletons while autowiring.
- Use ObjectContainer to resolve the WooCommerce class, everything
instantiated with "new" inside it, and all singletons that are
usually obtained via WC() function.
- Introduce the CustomerProvider class.
- Introduce a service provider to resolve WC_Queue_Interface,
this replaces the WC_Queue class.
- Mark as obsolete all the replaced "instance()" methods,
and the entire WC_Queue class.
Based on the design committee, we've decided not to use 'old' classes from the includes folder in new code in the 'src' directory. Thus removing those type hints, but leaving them in the docblock to not lose the information.
1. Use '0000-00-00 00:00:00' instead of CURRENT_TIMESTAMP as default value to support MySQL 5.6
2. Return early if DB version is less than 430 because then it would mean that required wc_reserved_stock table might not be present.
The root namespace of Core is Automattic\WooCommerce, but both the blocks and wc-admin plugins exist in this namespace. In an effort to prevent possible conflicts, we should not allow for overlap in our repository. The rationale behind doing this as opposed to renaming our root namespace feels reasonable. In the case of Blocks, all of the tooling is already set up in their repository, so all blocks should go there anyway. In the case of WC-Admin, we shouldn't be refactoring admin classes, as that would duplicate work done to revamp them entirely.
