It's been awhile since we have supported IE11 so it should be safe to remove
IntersectionObserver now.
From a TODO task in this repo:
> drop when we eventually drop IE11
Announcement of when we removed IE11 support:

This commit allows site admins to run theme tests in production via a new `/theme-qunit` route. When you visit `/theme-qunit`, you'll see a list of the themes/components installed on your site that have tests, and from there you can select a theme or component that you run its tests.
We also have a new rake task `themes:install_and_test` that can be used to install a list of themes/components on a temporary database and run the tests of the themes/components that are installed. This rake task can be useful when upgrading/deploying a Discourse instance to make sure that the installed themes/components are compatible with the new Discourse version being deployed, and if the tests fail you can abort the build/deploy process so you don't end up with a broken site.

Highlight.js changed their default branch from master to main. This switches to the @highlightjs/cdn-assets package, thus sidestepping the problem. It's a slightly cleaner integration though (no need to build locally anymore).
To prevent opaque cache files, now all the CDN files will be requested in 'cors' mode if the cdn_cors_enabled global setting is enabled. Before enabling the setting, should enable the cors in the CDN server by adding the response header `access-control-allow-origin: *` or `access-control-allow-origin: https://discourse.example.com.`
And other external file requests other than CDN will not be cached if the response type is opaque.
We can't use erb in ember-cli, and it seems the emoji groups rarely
change anyway. This commit migrates the ERB to pre-rendered javascript
that is updated via the `rake javascript:update_constants` task.
This moves the library into our lib folder, and refactored it to more
modern Javascript. I've kept the MIT license at the top of the file.
Doing this allows us to import it as a library in Ember CLI and ditch
yet another global variable.
This reverts commit e3de45359f.
We need to improve out strategy by adding a cache breaker with this change ... some assets on CDNs and clients may have incorrect CORS headers which can cause stuff to break.
We can't use erb in Ember CLI (since it does not have Ruby) so this has
been ported to use our `javascript:update_constants` rake test instead.
Note we don't have to run this every time a notification type as it's
only used by fixtures to fill in some specific types we test against.
* DEV - versions of JS files written to a JS file to be included by load-script and appended as params to URLs
* Formatting
* Incorporate feedback from PR
* Update filename of public-js-versions
The poll breakdown modal replaces the grouped pie charts feature.
Includes:
* MODAL: Untangle `onSelectPanel`
Previously modal-tab component would call on click the onSelectPanel callback with itself (modal-tab) as `this` which severely limited its usefulness. Now showModal binds the callback to its controller.
"The PR includes a fix/change to d-modal (b7f6ec6) that hasn't been extracted to a separate PR because it's not currently possible to test a change like this in abstract, i.e. with dynamically created controllers/components in tests. The percentage/count toggle test for the poll breakdown feature is essentially a test for that d-modal modification."
Some definitions rely on others, in particular the c/cpp/c-like ones,
and we were appending the bundle of all files in the folder.
Instead for testing I've limited us to just three definitions. This has
the benefit of being a lot smaller to download/parse in test mode too.
Adds a new rake task to auto generate a constants.js file with the
constants present. This makes migrating to Ember CLI easier, but also
slightly speeds up asset compilation by having to do less work.
If the constants change you need to run:
`rake javascripts:update_constants`
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
Uses github.com/discourse/moment-timezone-names-translations to translate timezone names.
Plugins can also provide their own timezone name translations.
Moves Highlight.js files to vendor/assets/javascripts
Adds Highlight.js in yarn package management
Removes old rake task and reliance on NPM to build Highlight.js
Highlight.js is now integrated in the "javascript:update" rake task
This feature is used for defer loading of images and in future for post cloaking
This gives us a polyfill so we can safely use the feature in problem browsers
The polyfill supports "polling" but it does not appear we need it yet.
If we discover anything odd here, consider setting poll interval per:
https://github.com/w3c/IntersectionObserver/tree/master/polyfill
```
var io = new IntersectionObserver(callback);
io.POLL_INTERVAL = 100; // Time in milliseconds.
```
Keeping the mutation observer cause we often mutate the DOM
