Introduce a global config flag `DISABLED_COMMERCE` to toggle buy functionality availability. Raise specific `DisabledCommerceError` when buying is disabled, ensuring end-users are informed. Additionally, reformat code for readability and consistency, improving overall maintainability.
Change promotions to inactive instead of deleting them to maintain data integrity. Adjust Celery logging levels to be DEBUG/INFO based on the DEBUG setting, improving log granularity during development and clarity in production.
Replaced hardcoded host checks with a dynamic check using `ALLOWED_HOSTS` from environment variables. Adjusted exception logging to include tracebacks only when the `DEBUG` environment variable is enabled.
Refactored Celery configurations to enhance task reliability, including changes to prefetch multiplier and timeout settings. Updated the worker command in `docker-compose.yml` to specify concurrency, memory limits, and task timeouts. Added a memory limit for the worker service to improve resource management.
Introduce a unique, auto-generated slug field to the Product model, populated from category, brand, and name. Update core filters, serializers, sitemaps, and GraphQL object types to support the new slug functionality. Also, enforce HTTP-only cookies for session, CSRF, and language for improved security.
