    Key Technical Parameters

    • SQL Query Optimisation: The module is designed to eliminate the N+1 query problem. Product data is retrieved in a single consolidated query, significantly reducing database load during feed generation.
    • File-Based Cache (12h): A 12-hour XML file refresh cycle — with support for manual invalidation — ensures high feed availability at minimal CPU cost.
    • Endpoint Security: Optional authorisation via a security token prevents unauthorised access to the full product catalogue and pricing data by third parties.
    • Multistore Compatibility: Full data isolation per shop in a Multistore environment — independent cache files, tokens and configuration values for each store context.

    Data Fields Exported to Google

    The module automatically maps and exports the key attributes required by Google Merchant Centre:

    XML Attribute Source in PrestaShop
    g:id / title Product ID and name as defined in the back office.
    g:price Gross price calculated within the current shop context (tax-inclusive).
    g:availability Automatic mapping of stock status (in stock / out of stock).
    g:gtin / g:brand EAN-13 barcode and manufacturer name.

    Implementation and Back Office

    The module is managed through a dedicated administration panel, which provides:

    • XML File Monitoring: Overview of the feed generation time and the age of the current cache file.
    • Access Management: Generation and rotation of the per-shop security token.
    • Rule Verification: Clear summary of product qualification criteria (active, visible in catalogue, price > 0, stock > 0).

    Free Version Specification (Core)

    Licence and Limitations:

    • Performance limit: Optimised for catalogues of up to 500 products.
    • Export scope: Base product only (product combinations/variants are not supported in the Core edition).
    • Context: Single language and currency per endpoint URL.
    • Requirements: Write access to the var/cache/prod/ directory.

    * A standard database backup is recommended prior to deploying the module in a production environment.

    ## [1.0.0] - 2026-02-28
    
    ### Added
    
    - Initial release of the `ppproductfeed` module (MVP edition) for PrestaShop 1.7.6+.
    - Public XML feed endpoint available at `module/ppproductfeed/feed`.
    - Google Shopping feed generator built on `DOMDocument` with correct `g:` namespace handling.
    - Layered architecture: `ProductRepository` (data retrieval), `GoogleShoppingMapper` (field mapping), `FeedGenerator` (XML rendering).
    - Back office configuration panel with a ready-to-use feed URL field and one-click copy button.
    - Integration with PrestaPremium components: `PPAdminTabInstaller` and `PPUpdater`.
    - 12-hour file-based XML cache with atomic write (`rename()`) to prevent partial reads.
    - Optional per-shop security token (`PPPRODUCTFEED_TOKEN`) validated via `hash_equals()`.
    
    ### Changed
    
    - Hook `displayBackOfficeHeader` registered during module installation.
    - Back office asset loading (`views/css/admin.css`) restricted to the module configuration page only.
    
    ### Feed Scope (MVP)
    
    - Only products that are active and visible in the catalogue (`both`, `catalog`) are included.
    - Products with `quantity <= 0` or `price <= 0` are excluded automatically.
    - Maximum of `500` records per feed request (MVP performance limit).
    - Mapped Google Shopping fields: `id`, `title`, `description`, `link`, `image_link`, `availability`, `price`, `condition`, `brand`, `gtin`, `mpn`.
    - `g:condition` read from the product attribute (`new` / `used` / `refurbished`); values outside this set fall back to `new`.
    - Product variants (combinations) are **not exported** — base product only (`id_product_attribute = 0`).
    - Feed generated for one language and one currency per request (active shop context).
