We are using func_get_arg method to receive argument in a backward compatible way since we cannot modify function signature to add more params even with default params. Earlier I was hoping to use DI to create another child class with modified signature and load it depending upon where we are executing from, however since we had to revert DI, we add this workaround to unblock #27735.
- One dummy class used for tests had a 'final private' method, this
is not allowed in PHP 8 and so the method is now just 'private'.
- The AbstractServiceProvider class was using
ReflectionParameter::getClass. This is deprecated in PHP8 and thus
that usage has been replaced with an utility method that uses
the recommended replacement.
- Passing a string that represents a number but has spaces (e.g. ' 1 ')
now works as expected (the number is properly interpreted)
- Passing the boolean true now returns 1, not 0
- Passing an object throws an error, instead of returning 0
After the League's Container package has been reintroduced, all the
code that implements the dependency injection mechanism in woocommerce
can be brought back as well.
There's a number of places in the WooCommerce codebase where the
built-in function 'round' is executed passing a non-numeric value
(not a number and not a string that can be parsed as a number),
for example round(''). In PHP 7 this yields a value of 0, but in
PHP 8 this throws an error.
This commit adds a 'NumberUtil' class with a static 'round' method,
this method checks if the passed value is numeric and if so it just
executes the built-in function, otherwise it returns 0. And all the
calls to 'round' in the codebase are replaced with 'NumberUtil::round'.
Since reverting the PR at this point would be a mess I've gone ahead and removed the internals of the container. We should aim to keep the class since it's now part of our public API but it won't work as expected anymore. This is fine for now since we don't actually have anything in it!
1. Since our code style dictates that these be `final` methods, we shouldn't be concerned about overlap.
2. There is precedent for `init` methods as requirements before using class instances.
Since we need to maintain backwards compatibility for class constructors we should settle on using method injection instead of constructor injection. I've replaced the `Definition` class we're using with one that doesn't support constructor arguments and added a check for auto_arg addition. Note that we don't check for method existence in the extended container. This is because reflection is unnecessarily expensive and we should avoid it if at all possible.
If a class name is passed as a concrete, check that the class
constructor is public if it exists. If another type of concrete is
passed, check that it's valid (a callback or an object).
Also update the autoloader to check if the class file exists,
otherwise class_exists fails if a namespaced class doesn't exist.
The following methods are added and can be invoked using `WC()`,
they just redirect to the same methods in LegacyProxy:
call_function
call_static
get_instance_of
- Method and class renames.
- Removed unnecessary autoloader registration.
- Add a unit test for classes with non-object type hints
in constructor arguments.
- `get_instance_of` accepts now arguments to be passed to the
class constructor if necessary.
- `get_special_instance_of` method removed, instead, now if a method
named `get_instance_of_<lowercased class name>` exists in the class,
it is used to get the instance of the class.
- A couple more unit tests added.
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.
Since we were converting the field to lowercase we ended up inserting meta in all lowercase, regardless of what it was in the CSV file. We should only be using the normalized field name when looking at the default columns, and should instead rely on a case-insensitive regex for the special columns.
One thing to note is that we're still defaulting the $headers array to the normalized field, as we don't want to change what is being passed to the filter for unmapped columns.
