For historical reasons, Discourse has different initializers conventions than standard Ember:
```
| Ember | Discourse | |
| initializers | pre-initializers | runs once per app load |
| instance-initializers | (api-)initializers | runs once per app boot |
```
In addition, the arguments to the initialize function is different – Ember initializers get either the `Application` or `ApplicationInstance` as the only argument, but the "Discourse style" gets an extra container argument preceding that.
This is confusing, but it also causes problems with Ember addons, which expects the standard naming and argument conventions:
1. Typically, V1 addons will define their (app, instance) initializers in the `addon/(instance-)initializers/*`, which appears as `ember-some-addon-package-name/(instance-)initializers/*` in the require registry.
2. Just having those modules defined isn't supposed to do anything, so typically they also re-export them in `app/(instance-)initializers/*`, which gets merged into `discourse/(instance-)initializers/*` in the require registry.
3. The `ember-cli-load-initializers` package supplies a function called `loadInitializers`, which typically gets called in `app.js` to load the initializers according to the conventions above. Since we don't follow the same conventions, we can't use this function and instead have custom code in `app.js`, loosely based on official version but attempts to account for the different conventions.
The custom code that loads initializers is written with Discourse core and plug-ins/themes in mind, but does not take into account the fact that addons can also bring initializers, which causes the following problems:
* It does not check for the `discourse/` module prefix, so initializers in the `addon/` folders (point 1 above) get picked up as well. This means the initializer code is probably registered twice (once from the `addon/` folder, once from the `app/` re-export). This either causes a dev mode assertion (if they have the same name) or causes the code to run twice (if they have different names somehow).
* In modern Ember blueprints, it is customary to omit the `"name"` of the initializer since `ember-cli-load-initializers` can infer it from the module name. Our custom code does not do this and causes a dev mode assertion instead.
* It runs what then addon intends to be application initializers as instance initializers due to the naming difference. There is at least one known case of this where the `ember-export-application-global` application initialize is currently incorrectly registered as an instance initializer. (It happens to not use the `/addon` folder convention and explicitly names the initializer, so it does not trigger the previous error scenarios.)
* It runs the initializers with the wrong arguments. If all the addon initializer does is lookup stuff from the container, it happens to work, otherwise... ???
* It does not check for the `/instance-initializers/` module path so any instance initializers introduced by addons are silently ignored.
These issues were discovered when trying to install an addon that brings an application initializer in #22023.
To resolve these issues, this commit:
* Migrates Discourse core to use the standard Ember conventions – both in the naming and the arguments of the initialize function
* Updates the custom code for loading initializers:
* For Discourse core, it essentially does the same thing as `ember-cli-load-initializers`
* For plugins and themes, it preserves the existing Discourse conventions and semantics (to be revisited at a later time)
This ensures that going forward, Ember addons will function correctly.
Communities can use sidebar or header dropdown, therefore navigation menu is a better name settings in 2 places:
- Old user sidebar preferences;
- Site setting about default tags and categories.
* FEATURE: Content custom summarization strategies.
This PR establishes a pattern for plugins to register alternative ways of summarizing content by extending a class that defines an interface.
Core controls which strategy we'll use and who has access to it through the `summarization_strategy` and `custom_summarization_allowed_groups`. It also defines the UI for summarizing topics.
Other plugins can access this summarization mechanism and implement their features, removing cross-plugin customizations, as it currently happens between chat and the discourse-ai plugin.
* Group membership validation and rate limiting
* Work with objects instead of classes
* Port summarization feature from discourse-ai to chat
* Rename available summaries to 'Top Replies' and 'Summary'
When we introduced unicode support in the regular expressions used in watched words (9a27803) we didn't realize the cost adding the `u` flag would be.
Turns out, it's pretty bad when you have lots of regular expressions to test. A customer had slightly less than 200 watched words, and it would freeze the browser for about 2s on the first check of those regular expressions (roughly 10ms per regular expression).
This commit introduces a new field (`word`) to the serialized watched words which is then converted to a very fast and cheap regular expression on the client-side. We use that regexp to quicly check whether a matcher is even worth trying so that we don't incure the cost of compiling the expensive unicode regexp.
This commit also busts the `WordWatcher` cache since we added a new field to be serialized.
One nice side effect of using `matchAll` instead of a `while / exec` loop is that the likeliness of having a bad regexp matching infinitely is vastly reduced 🙌
Improves the layout of most grids in posts, by using `object-fit: cover` for most images. This allows images to better fill up the space, without changing their aspect ratio.
Clicking on TOC heading anchors in a subfolder setup was breaking the current URL for users.
Other than the fix this change introduces the ability to test the subfolder setup in system specs.
1. ember proxy stuff still isn't in a great shape, live-reload doesn't work yet, uploads made w/o subfolder won't work, custom fonts don't work, service worker doesn't work. But otherwise it's fine :P
2. I don't know why `HTTP_IF_MODIFIED_SINCE` can be an empty string. Don't have time to investigate, and fast_blank makes this fix an easy solution ;)
When we get to really big files, it's better to not have thousands
of small chunks, since we don't have a resume functionality if the
upload fails. Better to try upload less chunks even if those chunks
are bigger.
For example, with this change a 20GB file would go from 4000 chunks
of the default 5mb to 1000 chunks of the new 20mb size. Still a lot,
but perhaps more manageable.
This is somewhat experimental -- if we still don't see improvements
we can always change back.
* move the chat unread indicator to top to match the profile avatar indicator
* add white border to profile avatar indicator (badge notification) to match chat indicator and userstatus styling
* change `.urgent` to BEM
* congregate all styling into mixin
* update chat index to use mixin
* update thread indicator to use mixin
* update header indicator to use mixin

Why this change?
Currently, we're interpolating within a string to set the class for the
`DButton` component. However, the interpolation and formatting of our
handlebars templates result in unnecessary spaces being added to the
class attribute.
```
<button class="sidebar-section-header sidebar-section-header-collapsable btn-flat
btn
no-text
" aria-controls="sidebar-section-content-categories" aria-expanded="true" title="Toggle section" type="button">
...
</button>
```
This makes the HTML elements for buttons hard to read especially when
we're debugging issues in the console. After this change, this is what
we get:
```
<button class="sidebar-section-header sidebar-section-header-collapsable btn-flat btn no-text" aria-controls="sidebar-section-content-categories" aria-expanded="true" title="Toggle section" type="button">
...
</button>
```
Previously workbox JS was vendored into our git repository, and would be loaded from the `public/javascripts` directory with a 1 day cache lifetime. The main aim of this commit is to add 'cachebuster' to the workbox URL so that the cache lifetime can be increased.
- Remove vendored copies of workbox.
- Use ember-cli/broccoli to collect workbox files from node_modules into assets/workbox-{digest}
- Add assets to sprockets manifest so that they're collected from the ember-cli output directory (and uploaded to s3 when configured)
Some of the sprockets-related changes in this commit are not ideal, but we hope to remove sprockets in the not-too-distant future.
