In PHP 7 the mail function generates PHP-style end of lines (\n),
and that's what these unit tests were assuming; in PHP 8 however
the proper network-style end of lines (\r\n) are generated.
This commit fixes the tests to be compatible with both styles.
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.
The assertion is useless (the constant is already tested a few Lines
above), and it was failing in PHP 8 because 'auto' < 2 is evaluated
as false, while it's evaluated to true in PHP 7.
In PHP 8 required parameters after optional parameters in
function/method signatures trigger a deprecation notice. These type
of parameters are pointless since a value needs to always be
provided for them anyway, so they are actually de-facto required.
This commit converts all these not-so-optional parameters into
truly required parameters by removing their default values.
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'.
A mechanism for improved filtering by attribute for variations was
introduced some time ago. This mechanism implied maintaining term
relationships for variations, where the terms were the attributes
that defined the variation.
The mechanism was reverted because it was complex and presented many
issues, but the code that created those term relationships was kept.
This pull request removes that code and the associated unit tests.
This commit reverts the functionality introduced in PR #26260
(later refined by #27175, #27190, #27508) in which filtering by
attribute using the layered nav widget was improved to handle the
cases of variations out of stock. The revert is a response to the
numerous problems reported by users in Woo 4.4 and 4.5
Not all the code has been reverted, only the code that resulted in
visible functionality changes. Thus, the code that generates
term relationships for variations is still in place to keep database
consistency and to keep the reverting changes to the minimum needed.
