FEATURE: Include optimized thumbnails for topics (#9215) This introduces new APIs for obtaining optimized thumbnails for topics. There are a few building blocks required for this: - Introduces new `image_upload_id` columns on the `posts` and `topics` table. This replaces the old `image_url` column, which means that thumbnails are now restricted to uploads. Hotlinked thumbnails are no longer possible. In normal use (with pull_hotlinked_images enabled), this has no noticeable impact - A migration attempts to match existing urls to upload records. If a match cannot be found then the posts will be queued for rebake - Optimized thumbnails are generated during post_process_cooked. If thumbnails are missing when serializing a topic list, then a sidekiq job is queued - Topic lists and topics now include a `thumbnails` key, which includes all the available images: ``` "thumbnails": [ { "max_width": null, "max_height": null, "url": "//example.com/original-image.png", "width": 1380, "height": 1840 }, { "max_width": 1024, "max_height": 1024, "url": "//example.com/optimized-image.png", "width": 768, "height": 1024 } ] ``` - Themes can request additional thumbnail sizes by using a modifier in their `about.json` file: ``` "modifiers": { "topic_thumbnail_sizes": [ [200, 200], [800, 800] ], ... ``` Remember that these are generated asynchronously, so your theme should include logic to fallback to other available thumbnails if your requested size has not yet been generated - Two new raw plugin outlets are introduced, to improve the customisability of the topic list. `topic-list-before-columns` and `topic-list-before-link`
