Description

Subscription plugins create an order empty and add its items and totals afterwards, so the Purchase sent from woocommerce_new_order had no contents and a zero value. Woo Subscriptions, WP Swings Subscriptions and YITH Subscription all do this, each with a different save sequence.

Orders that have no items when woocommerce_new_order fires are now deferred and reported on shutdown from their persisted state, independent of the plugin that created them. Checkout orders have items at creation and are reported exactly as before. Orders still empty or deleted by the end of the request are skipped. Purchase tracking meta is still stripped when Subscriptions copies data onto renewal, resubscribe and parent orders, so stale flags cannot suppress the event.

Changelog entry

Fix missing product details in Purchase events for orders created by subscription plugins.

Test Plan

Tested with WooCommerce 11.1.0, HPOS enabled, Woo Subscriptions 8.2.0, WP Swings Subscriptions for WooCommerce 2.0.2 and YITH WooCommerce Subscription 4.17.0.

1. With tracking enabled, create a renewal through each plugin's own code: wcs_create_renewal_order(), wcs_create_resubscribe_order(), a generated parent order, a renewal from a subscription carrying stale tracking meta, and a real woocommerce_scheduled_subscription_payment run; WP Swings' HPOS renewal scheduler; YITH's renew_order(). Capture the outgoing Purchase with pre_http_request.
2. Verify each order produces one server Purchase whose content IDs, quantities, value, currency and order ID match the order, and that payment_complete() and two thank-you page loads add no further server event while reusing the same event ID.
3. Place a normal checkout order and confirm the Purchase still fires at creation, unchanged.
