get_related_products_query in the WC_Product_Data_Store_CPT class is
querying the suitable products with a "limit" clause, this causes
that products down in the table are never picked for display.
This commit adds a ORDER BY RAND() to the query so that all products
have a chance to get picked.
By adding this prevention, it also stops fatal errors (calling method on non-object) from happening down the line when working with the orders list that is always assumed to be a proper order object.
Example error this prevents:
```
Fatal error: Uncaught Error: Call to a member function get_items() on bool in /wp-content/plugins/woocommerce/includes/class-wc-order.php on line 1902
```
This commit re-works the `WC_Shipping_Zone_Data_Store::read()` method in the following ways:
1. Remove a confusing conditional (`if ( 0 !== $zone->get_id() || '0' !== $zone->get_id() ) { ... }`)
2. Return early if we're dealing with Zone 0, eliminating additional conditional steps
3. Add documentation for the "woocommerce_shipping_zone_loaded" action hook
Earlier, we were just showing an "Usage limit reached message", however in some cases, specially when user is logged in, we can also ask them to go to MyAccount page and cancel order if they'd like to (to free up the coupon). This will hopefully make for a better user experience.
When a simple product with downloads gets converted into a variable
product all the existing download permissions for past orders become
invalid. This commit adds an extra verification procedure to the
product save code:
- Get all the existing download permissions for the product and all
the children (variations)
- For each download permission for the parent product, if there's a
variation that offers the same file for download (same file URL)
AND an equivalent download permission doesn't exist (equivalent means
same file URL, same order id and same user id), then create it.
Additionally, a new WC_Customer_Download_Data_Store::create_from_data
method is added.
This commit replaces double quotes with single quotes inside a MySQL query to avoid a syntax error when the SQL mode ANSI_QUOTES is enabled in MySQL. When this mode is enabled, MySQL treats double quotes as identifiers (like the backtick character) instead of as string delimiters. Before this change, sites running with this mode enabled wouldn't be able to add products to orders created manually in the admin as the modified query would fail (other places that also use product search including variations would fail as well). The commit that introduced this issue shipped in WC 4.5.0 (see https://github.com/woocommerce/woocommerce/pull/27171).
This creates a tradeoff in optimizing repeated queries vs on off queries.
Another tradeoff is making more cache get calls as opposed to more SQL calls.
Primary reason for dropping the cache hydration is that seems like we can acheive the same results without it, so no need to add this additional complexity to our code.
With PHP 8.0, non-strict comparisons between integers and strings containing
non-numeric characters are being tightened. This affects comparisons like:
0 < '0000-00-00 00:00:00'
PHP 8.0 that equates to true whereas prior to 8.0 it would be false.
