Why is this change required?
When a site is newly setup and a user has just been created, the
categories and tags sections are hidden from the user. This happens
because the admin has not configured the `default_navigation_menu_categories` or
`default_navigation_menu_tags` site settings. When the categories and tags
sections are hidden from the user, the sidebar looks extremely bare and
does not create a good experience.
What is being change?
In this commit, we're changing the logic such that the site's top
categories and tags are displayed if the user does not have any
categories/tags configured in each respective section. The only
regression introduced in this change is that the categories and tags
section can no longer be hidden as a result. However, we have plans to
address this in the future by allowing sidebar sections to be configured
to be hidden by each individual user.

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: Implement max_tags_per_email_subject
* made it so only max_tags_per_email_subject is responsible for tags in emails when the feature is enabled
* added locales for implemented siteSettings
* reworded locale for enable_max_tags_per_email_subject
* added min value for max_tags_per_email_subject
* Implemented suggested changes to spec description
Currently, groups owned by moderators are not visible to them on the
groups page. This happens because, the group visibility queries don't
account for non-admin staff user group ownership.
This change updates the group visibility scope queries to account for a
moderator(non-admin staff user) group ownership.
When we introduced the new quote format with full-name display name:
```
[quote="Ted Johansson, post:1, topic:2, username:ted"]
we overlooked the code responsible for rewriting quotes when a user's name is changed.
```
The functional part of this change adds support for the new quote format in the code that updates quotes when a user's username changes. See the test case in `spec/services/username_changer_spec.rb` for the details.
In addition, this change adds a regression test for PrettyText to cover the new quote format, and extracts the code responsible for rewriting raw and cooked quotes into its own `QuoteRewriter` class. The functionality of the latter is tested through the tests in `spec/services/username_changer_spec.rb`.
Anonymization is among the most expensive operations we can perform with
extreme potential to impact the database. To mitigate risk we only allow a
single anonymization across the entire cluster concurrently.
This commit introduces support for `cluster_concurrency 1`. When you set that on a Job it will only allow 1 concurrent execution per cluster.
* 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.
This patch sets some limits on custom fields:
- an entity can’t have more than 100 custom fields defined on it
- a custom field can’t hold a value greater than 10,000,000 characters
The current implementation of custom fields is relatively complex and
does an upsert in SQL at some point, thus preventing to simply add an
`ActiveRecord` validation on the custom field model without having to
rewrite a part of the existing logic.
That’s one of the reasons this patch is implementing validations in the
`HasCustomField` module adding them to the model including the module.
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.
