**TL;DR:** Refactor autocomplete to use async markdown parsing for code block detection.
Previously, the `inCodeBlock` function in `discourse/app/lib/utilities.js` used regular expressions to determine if a given position in the text was inside a code block. This approach had some limitations and could lead to incorrect behavior in certain edge cases.
This commit refactors `inCodeBlock` to use a more robust algorithm that leverages Discourse's markdown parsing library.
The new approach works as follows:
1. Check if the text contains any code block markers using a regular expression.
If not, return `false` since the cursor can't be in a code block.
1. If potential code blocks exist, find a unique marker character that doesn't appear in the text.
1. Insert the unique marker character into the text at the cursor position.
1. Parse the modified text using Discourse's markdown parser, which converts the markdown into a tree of tokens.
1. Traverse the token tree to find the token that contains the unique marker character.
1. Check if the token's type is one of the types representing code blocks ("code_inline", "code_block", or "fence").
If so, return `true`, indicating that the cursor is inside a code block.
Otherwise, return `false`.
This algorithm provides a more accurate way to determine the cursor's position in relation to code blocks, accounting for the various ways code blocks can be represented in markdown.
To accommodate this change, the autocomplete `triggerRule` option is now an async function.
The autocomplete logic in `composer-editor.js`, `d-editor.js`, and `hashtag-autocomplete.js` has been updated to handle the async nature of `inCodeBlock`.
Additionally, many of the tests have been refactored to handle async behavior. The test helpers now simulate typing and autocomplete selection in a more realistic, step-by-step manner. This should make the tests more robust and reflective of real-world usage.
This is a significant refactor that touches multiple parts of the codebase, but it should lead to more accurate and reliable autocomplete behavior, especially when dealing with code blocks in the editor.

Changing an `@tracked` value in a `willDestroyElement` hook will not immediately trigger a re-render. Instead, it seems to update on the next natural runloop iteration, which may be significantly later depending on what else is happening.
Instead, these kinds of 'data' changes should be made based on the lifecycle of the component instance (init / willDestroy). Making changes to tracked properties here does seem to cause immediate invalidation & re-render.
There are a couple of reasons for this.
The first one is practical, and related to eager loading. Since /lib is not eager loaded, when the application boots, ProblemCheck["identifier"] will be nil because the child classes aren't loaded.
The second one is more conceptual. There turns out to be a lot of inter-dependencies between the part of the problem check system that live in /app and the parts that live in /lib, which probably suggests it should all go in /app.
Why this change?
On the `/admin/customize/themes/<:id>` route, we allow admins to edit
all settings via a settings editor. Prior to this change, trying to edit
and save a typed objects theme settings will result in an error on the
server.
Why this change?
On a slow network, using the `AceEditor` component will result in a blob
of text being shown first before being swapped out with the `ace.js`
editor after it has completed loading.
There is also a problem when setting the theme for the editor which
would result in a "flash" as reported in
https://github.com/ajaxorg/ace/issues/3286. To avoid this, we need to
load the theme js file before displaying the editor.
What does this change do?
1. Adds a loading spinner and set the `div.ace` with a `.hidden` class.
2. Once all the relevant scripts and initialization is done, we will
then remove the loading spinner and remove `div.ace`.
This change creates a user setting that they can toggle if
they don't want to receive unread notifications when someone closes a
topic they have read and are watching/tracking it.
* A11Y: Update bulk selection keyboard shortcuts
Still a draft, but in current state this:
- adds `shift+b` as a keyboard shortcut to toggle bulk select
- adds `shift+d` as a keyboard shortcut to dismiss selected topic(s) (this
replaces `x r` and `x t` shortcuts)
- adds `x` as a keyboard shortcut to toggle selection (while in bulk select mode)
- fixes a bug with the `shift+a` shortcut, which was not working properly
Note that there is a breaking change here. Previously we had:
- `x r` to dismiss new topics
- `x t` to dismiss unread topics
However, this meant that we couldn't use `x` for selection, because the
itsatrap library does not allow the same character to be used both as a
single character shortcut and as the start of a sequence. The proposed
solution here is more consistent with other apps (Gmail, Github) that use
`x` to toggle selection.
Also, we never show both "Dismiss New" and "Dismiss Unread" in the same
screen, hence it makes sense to consolidate both actions under `shift+d`.
* Address review
Why this change?
Before this change, the new navigation item in the topic list will be
hidden when there are no new or unread topics for the user. We have
started to find this behaviour confusing UX wise so we decided to stop
hiding it.
Why this change?
This is a regression from introduced in
5c1147adf3 where dismissing unread topics
was changing the notification level of the topics instead of just
dismissing the unread posts.
What does this change do?
1. Bring back the previous implementation of the action
2. Fix the system test that was supposed to catch the problem but did
not.
The `home-logo-wrapper` outlet is used by chat, which means it is unavailable for use by any other themes/plugins. This commit introduces a second nested outlet called `home-logo` which can be used to replace the logo without affecting chat's header logic.
This commit improves the "+ X subcategories" option that shows sometimes
in the category selector. It used to show when there was a single match,
but now it also shows up on exact matches even though there are multiple
results.
It also makes it work when lazy_load_categories is enabled by searching
the subcategories before rendering them.
When "lazy load categories" is enabled, the CategoryDrop component will
render at most 15 categories. If there are more categories, a "Show
more" link pointing to the categories page will be displayed.
Doing the following renames:
Jobs::ProblemChecks → Jobs::RunProblemChecks
Jobs::ProblemCheck → Jobs::RunProblemCheck
This is to disambiguate the ProblemCheck class name, ease fuzzy finding, and avoid needing to use :: in a bunch of places.
Before, the `back to forum` link was part of experimental admin navigation. It means that the link could be filtered out.
Because it is essential navigation, it should not be part of sidebar links and should be moved above the filter.
This option was introduced at some point in the past, but was removed
during the work necessary to make Discourse work with a large number of
categories.

Sometimes we add scripts outside of Rails. This commit provides a way to generate a nonce placeholder even if you don't have access to an ApplicationController instance.
Why this change?
There are two problematic queries in question here when loading
notifications in various tabs in the user menu:
```
SELECT "notifications".*
FROM "notifications"
LEFT JOIN topics ON notifications.topic_id = topics.id
WHERE "notifications"."user_id" = 1338 AND (topics.id IS NULL OR topics.deleted_at IS NULL)
ORDER BY notifications.high_priority AND NOT notifications.read DESC,
NOT notifications.read AND notifications.notification_type NOT IN (5,19,25) DESC,
notifications.created_at DESC
LIMIT 30;
```
and
```
EXPLAIN ANALYZE SELECT "notifications".*
FROM "notifications"
LEFT JOIN topics ON notifications.topic_id = topics.id
WHERE "notifications"."user_id" = 1338
AND (topics.id IS NULL OR topics.deleted_at IS NULL)
AND "notifications"."notification_type" IN (5, 19, 25)
ORDER BY notifications.high_priority AND NOT notifications.read DESC, NOT notifications.read DESC, notifications.created_at DESC LIMIT 30;
```
For a particular user, the queries takes about 40ms and 26ms
respectively on one of our production instance where the user has 10K notifications while the site has 600K notifications in total.
What does this change do?
1. Adds the `index_notifications_user_menu_ordering` index to the `notifications` table which is
indexed on `(user_id, (high_priority AND NOT read) DESC, (NOT read)
DESC, created_at DESC)`.
1. Adds a second index `index_notifications_user_menu_ordering_deprioritized_likes` to the `notifications`
table which is indexed on `(user_id, (high_priority AND NOT read) DESC, (NOT read AND notification_type NOT IN (5,19,25)) DESC, created_at DESC)`. Note that we have to hardcode the like typed notifications type here as it is being used in an ordering clause.
With the two indexes above, both queries complete in roughly 0.2ms. While I acknowledge that there will be some overhead in insert,update or delete operations. I believe this trade-off is worth it since viewing notifications in the user menu is something that is at the core of using a Discourse forum so we should optimise this experience as much as possible.
* DEV: add topic-map-expanded glimmer component
* DEV: remove topic-map-expanded widgets from topic-map
* DEV: add noreferrer for _blank target and add table grouping to template
* DEV: negate base styling of tbody element so expanded topic map retains current look
* DEV: pass in title to TopicParticipants as internationalized string instead of renderable HTML and set TRUNCATED_LINKS_LIMIT constant
Why this change?
The `/admin/customize/themes/:id/schema/name` route is a work in
progress but we want to be able to start navigating to it from the
`/admin/customize/themes/:id` route.
What does this change do?
1. Move `adminCustomizeThemes.schema` to a child route of
`adminCustomizeThemes.show`. This is because we need the model
from the parent route and if it isn't a child route we end up
having to load the theme model again from the server.
1. Add the `objects_schema` attribute to `ThemeSettingsSerializer`
1. Refactor `SiteSettingComponent` to be able to render a button
so that we don't have to hardcode the button rendering into the
`SiteSettings::String` component
* UX: chat message creator scss cleanup + design tweak to username display
* add user status with live updates to modal
* show user status description in modal
* add tests for user status
* UX: add user-status styling to chat message creator

Skipping babel for qunit is part of the default embroider blueprint. Adding these doesn't seem to have a measurable effect on build time, but it does stop this message from being printed in the build log:
```
The code generator has deoptimised the styling of /Users/david/discourse/discourse/node_modules/sinon/pkg/sinon-esm.js as it exceeds the max of 500KB

Adds a site setting to include a post's content in penalty message.
When silencing/suspending a user from a post, or a reviewable with
a post, adds an option to include a post's content in the email
message by default.
When a post is created by an incoming email, we show
an envelope icon on it which then opens a modal with the
raw email contents. Previously this was staff (admin+mod)
only, but now this commit adds the `view_raw_email_allowed_groups`
site setting, so any group can be added to give users permission
to see this.
CategoryChooser component usually displays just categories, but
sometimes it can show two none values: a "no category" or Uncategorized.
This commit makes sure that these are rendered correctly.
The problem was that the "none" item was automatically inserted in the
list of options, but that should not always happen. Toggling option
`autoInsertNoneItem` requires setting `none` too.
With the adjustments of `btn-transparent` in https://github.com/discourse/discourse/pull/24666, there are more buttons that could use this class instead of `btn-flat`. This mostly relates to `x` close buttons, but also includes composer and chat toggles.
The primary difference between these styles is that `btn-transparent` never has a background, where `btn-flat` may have a hover or focus background.
Why this change?
Prior to this change, the `CategoryList#find_relevant_topics` method was
loading and allocating all `CategoryFeaturedTopic` records in the
database to eventually only just use its `category_id` and `topic_id`
column. On a site with many `CategoryFeaturedTopic` records, the loading
of the ActiveRecord objects is a source of bottleneck.
The other problem with the `CategoryList#find_relevant_topics` method is
that it is unconditionally loading all records from the database even if
the user does not have access to the category. This again is wasteful.
What does this change do?
This commit makes it such that `CategoryList#find_relevant_topics` is
called only after `CategoryList#find_categories` in the `CategoryList#initialize`
method so that we can filter featured topics against categories that the
user has access to.
The second change is that Instead of loading `CategoryFeaturedTopic` records, we make an
inner join agains the `topics` table instead and skip any allocation of
`CatgoryFeaturedTopic` ActiveRecord objects.
When we send a bookmark reminder, there is an option to delete
the underlying bookmark. The Notification record stays around.
However, if you want to filter your notifications user menu
to only bookmark-based notifications, we were not showing unread
bookmark notifications for deleted bookmarks.
This commit fixes the issue _going forward_ by adding the
bookmarkable_id and bookmarkable_type to the Notification data,
so we can look up the underlying Post/Topic/Chat::Message
for a deleted bookmark and check user access in this way. Then,
it doesn't matter if the bookmark was deleted.
