This commits adds the ability to add a header to the embedded comments
view. One use case for this is to allow `postMessage` communication
between the comments iframe and the parent frame, for example, when
toggling the theme of the parent webpage.
This simplifies the crawler-linkback-list to only be a point of reference to the actual DiscussionForumPosting objects.
See "Summary page": https://developers.google.com/search/docs/advanced/structured-data/carousel?hl=en#summary-page
> [It] defines an ItemList, where each ListItem has only three properties: @type (set to ListItem), position (the position in the list), and url (the URL of a page with full details about that item).
This replaces the position declared as `#123` with the more simple version `123`.
The property position may be of type Integer or Text. A value of type Integer, or more precise of type Text which simply casts to integer, is sufficient here.
See: https://schema.org/position
In category-view the topic-list already uses this notation for the position of topics:
`<meta itemprop="position" content="123">`
Currently when generating a onebox for Discourse topics, some important
context is missing such as categories and tags.
This patch addresses this issue by introducing a new onebox engine
dedicated to display this information when available. Indeed to get this
new information, categories and tags are exposed in the topic metadata
as opengraph tags.
Use the `Discourse.base_path` when linking to hard coded images used in
the UI so that the correct subfolder path is used if present.

* FIX: broken emoji url on password reset w/ subfolder
* Use Discourse.base_path to account for subfolder
I do like where you are going with using Emoji.url_for but due to the
lack of svg support currently I think we need to use the current svg
file we have. The emoji png files we have render too blurry at high
resolution.
This commit uses the `Discourse.base_path` so that a subfolder install
will have the correct image path.
I do think in the future we should do some work around using a helper
similar to Emoji.url_for with svg support so that we better standardize
our use of these emojis.

Meta topic: https://meta.discourse.org/t/meta-theme-color-is-not-respecting-current-color-scheme/239815/7?u=osama.
This commit renders an additional `theme-color` `<meta>` tag for the dark scheme if the current user/request has a scheme selected for dark mode. We currently only render one `theme-color` tag which is always based on the user's selected scheme for light mode, but if the user also selects a scheme for dark mode and uses a device that's configured to use/prefer dark mode, the Discourse UI will be in dark mode, but any parts of the browser/OS UI that's colored based on the `theme-color` tag, would use a color from the user's selected light scheme and look inconsistent with the Discourse UI because the `theme-color` tag is based on the user's selected light scheme.
The additional `theme-color` tag has `media="(prefers-color-scheme: dark)"` and is based on the user's selected dark scheme which means any browser UI that's colored based on `theme-color` tags should be able to pick the right tag based on the user's preference for light/dark mode.

Experiment moving from preload tags in the document head to preload information the the response headers.
While this is a minor improvement in most browsers (headers are parsed before the response body), this allows smart proxies like Cloudflare to "learn" from those headers and build HTTP 103 Early Hints for subsequent requests to the same URI, which will allow the user agent to download and parse our JS/CSS while we are waiting for the server to generate and stream the HTML response.

This lets us use all our normal JS tooling like prettier, esline and babel on the splash screen JS. At runtime the JS file is read and inlined into the HTML. This commit also switches us to use a CSP hash rather than a nonce for the splash screen.
When `EMBER_CLI_PLUGIN_ASSETS=1`, plugin application JS will be compiled via Ember CLI. In this mode, the existing `register_asset` API will cause any registered JS files to be made available in `/plugins/{plugin-name}_extra.js`. These 'extra' files will be loaded immediately after the plugin app JS file, so this should not affect functionality.
Plugin compilation in Ember CLI is implemented as an addon, similar to the existing 'admin' addon. We bypass the normal Ember CLI compilation process (which would add the JS to the main app bundle), and reroute the addon Broccoli tree into a separate JS file per-plugin. Previously, Sprockets would add compiled templates directly to `Ember.TEMPLATES`. Under Ember CLI, they are compiled into es6 modules. Some new logic in `discourse-boot.js` takes care of remapping the new module names into the old-style `Ember.TEMPLATES`.
This change has been designed to be a like-for-like replacement of the old plugin compilation system, so we do not expect any breakage. Even so, the environment variable flag will allow us to test this in a range of environments before enabling it by default.
A manual silence implementation is added for the build-time `ember-glimmer.link-to.positional-arguments` deprecation while we work on a better story for plugins.
Previously, this would require manually adding `?safe_mode=...` multiple times during the email-based login flow. `/u/admin-login` is often used when debugging a site, so it makes sense for this to be easier.
This commit introduces a new checkbox on the `/u/admin-login` screen. When checked, it'll set the safe_mode parameter on the `/email-login` link, and then pass it all the way through to the homepage redirect.
- `no_custom` -> `no_themes` (history: before themes existed, we had a similar tool called 'customizations')
- `only_official` -> `no_unofficial_plugins` (matches format of `no_themes` and `no_plugins`, and makes it clear that this doesn't affect themes)
- `?safe_mode=no_themes%2C%no_plugins` -> `?safe_mode=no_themes,no_plugins` (the query portion of a URL does not require commas to be encoded. This is much nicer to read)
- If `no_plugins` is chosen from `/safe-mode` the URL generated will omit the superfluous `no_unofficial_plugins` flag
- Some tweaks to copy on `/safe-mode`

Follow up to: #17619
Context: https://meta.discourse.org/t/introducing-discourse-splash-a-visual-preloader-displayed-while-site-assets-load/232003/17
We previously relied on the user's browser when deciding when to show the splash in light/dark mode. This worked well but can fail if the user manually selects a theme with a default "dark" scheme.
This PR will now factor that in. If the user selects a theme with a default dark scheme, use that. If a user selects a theme with a "light" default scheme and also picks a secondary "dark" scheme, use the media detection we had before.
This PR also removes the dark mode theme-color that was added in the previous PR. That will now go in a separate PR
Context: https://meta.discourse.org/t/introducing-discourse-splash-a-visual-preloader-displayed-while-site-assets-load/232003/17
We currently set the theme secondary color as the background for the splash, and this works and respects light/dark modes.
The issue is that we set it on the #d-splash div. That div doesn't have a specified height and only gets its height when the splash image loads.
This can cause a flicker effect where the <HTML> background shows for a fraction of a second while the splash image loads.
This PR sets the theme color on the <HTML> tag to alleviate this. This allows us to set the theme color a little bit sooner and should hopefully prevent the flicker effect from happening.
This PR also adds the theme-color <meta> tag for dark mode. Browsers that don't support multiple theme-color tags will ignore the second tag and fall back to the first one.
This commit introduces a new plugin API to register
a group of stats that will be included in about.json
and also conditionally in the site about UI at /about.
The usage is like this:
```ruby
register_about_stat_group("chat_messages", show_in_ui: true) do
{
last_day: 1,
"7_days" => 10,
"30_days" => 100,
count: 1000,
previous_30_days: 120
}
end
```
In reality the stats will be generated any way the implementer
chooses within the plugin. The `last_day`, `7_days`, `30_days,` and `count`
keys must be present but apart from that additional stats may be added.
Only those core 4 stat keys will be shown in the UI, but everything will be shown
in about.json.
The stat group name is used to prefix the stats in about.json like so:
```json
"chat_messages_last_day": 2322,
"chat_messages_7_days": 2322,
"chat_messages_30_days": 2322,
"chat_messages_count": 2322,
```
The `show_in_ui` option (default false) is used to determine whether the
group of stats is shown on the site About page in the Site Statistics
table. Some stats may be needed purely for reporting purposes and thus
do not need to be shown in the UI to admins/users. An extension to the Site
serializer, `displayed_about_plugin_stat_groups`, has been added so this
can be inspected on the client-side.
The dots in the splash were previously hard-coded (v1). This PR makes progress towards making them be based on current theme colors.
Note that this is an improvement and not the "final" version. We're going to dynamically generate the splash file and the base64 URL later on.
This commit adds preload links for core/plugin/theme CSS stylesheets in the head.
Preload links are non-blocking and run in parallel. This means that they should have already been downloaded by the time we use the actual stylesheets (in the <body> tag).
Google is currently complaining about this here and this PR will address that warning.
This commit will also fix an issue in the splash screen where it sometimes doesn't respect the theme colors - causing a slightly jarring experience on dark themes.
Note that I opted not to add new specs because the underlying work required already has a lot of coverage. The new methods only change the output HTML so we can chuck that in the document <head>
This change also means that we can make all the stylesheets non-render blocking, but that will follow in a separate commit.
We previously used the window load event as a target to remove the splash. The issue with that is that it means we wait for images to download before we remove the splash.
Ember has a better method that we can use ready(). This PR triggers a custom discourse-ready when that happens and uses that as the baseline for removing the splash.
This PR also adds three new performance marks. discourse-ready, discourse-splash-visible, and discourse-splash-removed
These will help us keep track of performance.
Internal topic /t/65378/81
We previously relied on CSS animation-delay for the splash. This means that we can get inconsistent results based on device/network conditions.
This PR moves us to a more consistent timing based on {request time + 2 seconds}
