eCommerce Pager Guard
by Terrabit https://www.terrabit.ro , Dorin Hongu https://www.terrabit.roeCommerce Pager Guard
Makes the shop return 404 for listing pages that do not exist.
Odoo’s pager() helper clamps an out-of-range page number to the last real page rather than refusing it. /shop/page/999999 therefore answers 200 with the content of the last page — and a crawler reads that as confirmation that the page exists, follows the pattern upwards and never stops.
On a production site this produced 2.386 requests per day against a single /shop/category/…/page/3467514 URL, each one paying for a full product search and QWeb render before serving duplicate content.
This module compares the requested page against the pager’s own page_count and raises NotFound when it is higher. /shop itself and the last real page are unaffected, so search engines get a clean signal that the URL space is finite.
Deliberately no hardcoded page ceiling: a real catalogue was measured at 2.578 shop pages, so even a limit that looks generous would refuse most of the listing. The page count is only known once the products are counted, which is why the check runs after super(). That still avoids the expensive part — request.render is lazy in Odoo, so raising there means the QWeb template is never rendered.

History
19.0.1.0.0 (2026-07-30)
- Initial release. Shop listing pages beyond the last real one now return 404 instead of being silently clamped to the last page by portal.controllers.portal.pager, which made every /shop/page/N answer 200 with duplicate content and left crawlers walking the page number upwards without end.
