This change automatically resizes icons for various purposes. Admins can now upload `logo` and `logo_small`, and everything else will be auto-generated. Specific icons can still be uploaded separately if required.
## Core
- Adds an SiteIconManager module which manages automatic resizing and fallback
- Icons are looked up in the OptimizedImage table at runtime, and then cached in Redis. If the resized version is missing for some reason, then most icons will fall back to the original files. Some icons (e.g. PWA Manifest) will return `nil` (because an incorrectly sized icon is worse than a missing icon).
- `SiteSetting.site_large_icon_url` will return the optimized version, including any fallback. `SiteSetting.large_icon` continues to return the upload object. This means that (almost) no changes are required in core/plugins to support this new system.
- Icons are resized whenever a relevant site setting is changed, and during post-deploy migrations
## Wizard
- Allows `requiresRefresh` wizard steps to reload data via AJAX instead of a full page reload
- Add placeholders to the **icons** step of the wizard, which automatically update from the "Square Logo"
- Various copy updates to support the changes
- Remove the "upload-time" resizing for `large_icon`. This is no longer required.
## Site Settings UX
- Move logo/icon settings under a new "Branding" tab
- Various copy changes to support the changes
- Adds placeholder support to the `image-uploader` component
- Automatically reloads site settings after saving. This allows setting placeholders to change based on changes to other settings
- Upload site settings will be assigned a placeholder if SiteIconManager `responds_to?` an icon of the same name
## Dashboard Warnings
- Remove PWA icon and PWA title warnings. Both are now handled automatically.
## Bonus
- Updated the sketch logos to use @awesomerobot's new high-res designs
* improved emoji support
- always optimize images as part of the task
- use the unicode standard ordering/naming for sections
* UX: more height for when there are recently used
This commit adds a new property "discourseReferrerPolicy" to the
set of supported configuration properties for the comment embed
script. If provided the value will be used to set the "referrerPolicy"
attribute on the iframe created to display the comments. This in turn
will allow embedding pages to define a more lenient referer policy on
the embed iframe for pages whose default policy is so strict it
keeps the comment embed from working.
Example:
* Setup:
* Discourse hosted at discourse.example.com
* Comments embedded at example.com
* Referrer-Policy at example.com set to 'same-origin'
* Without this commit:
* Loading the comments fails due to the referer being empty
* With this commit and no adjusted configuration:
* Loading the comments fails due to the referer being empty
(= same behaviour as without the commit)
* With this commit and DiscourseEmbed.discourseReferrerPolicy =
'no-referrer-when-downgrade' as additional configuration:
* Loading the comments succeeds
Note that this change is of special interest for embedding pages
wanting to restrict data flows under the terms of the GDPR since
it allows selectively whitelisting comment embeds while preventing
referer leaking by default.
This is the first iteration of an effort towards making a very good dashboard.
Until we feel confident this is good, this dashboard will only be accessible through /admin/dashboard_next
* set up static offline.html route and service worker for Android Web App Banner
* add viewport meta tag to offline view for android app banner
* add i18n support for offline.html pages, cleanup
* fix html syntax, add page title, remove license for service-worker.js
