- 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.
