NOTE: Most of this is experimental and will be removed at a later
time, which is why things like translations have not been added.
The new /admin-revamp UI uses a sidebar for admin nav. This initial
step adds a script to generate a map of all the current admin nav
into a format the sidebar to read. Then, people can experiment
with different changes to this structure.
The structure can then be edited from `/admin-revamp/config/sidebar-experiment`,
and it is saved to local storage so people can visually experiment with different ways
of showing the admin sidebar links.
Previously, focus wasn't being applied correctly on dialogs using named
components. This was because the A11YDialog was being invoked before
the component was completely rendered.
The long-term plan is to move away from A11YDialog doing the rendering
here, but for now this should do.
As much as possible I would like us to avoid having to go the with a global event listener on click/mouseover. For now I have removed all cases of `data-tooltip`, if we clearly identify a use case of a global event listener we might reconsider this.
The following changes are also included:
- by default tooltips won't attempt to focus first focusable element anymore
- tooltip will now use `cursor: pointer` by default
- a new service has been introduced: `InternalTooltip` which is responsible to track the current instance displayed by a `<DTooltip />`. Portal elements when replaced are not properly cleaned and I couldn't figure out a way to have a proper hook to ensure the previous `DTooltipInstance` is properly set as not expanded; this problem was very visible when using a tooltip as interactive and hovering another tooltip, which would replace the interactive tooltip as not closed.
This commit adds a new admin UI under the route `/admin-revamp`, which is
only accessible if the user is in a group defined by the new `enable_experimental_admin_ui_groups` site setting. It
also adds a special `admin` sidebar panel that is shown instead of the `main`
forum one when the admin is in this area.

We also add an "Admin Revamp" sidebar link to the community section, which
will only appear if the user is in the setting group:
![image](https://github.com/discourse/discourse/assets/920448/ec05ca8b-5a54-442b-ba89-6af35695c104)
Within this there are subroutes defined like `/admin-revamp/config/:area`,
these areas could contain any UI imaginable, this is just laying down an
initial idea of the structure and how the sidebar will work. Sidebar links are
currently hardcoded.
Some other changes:
* Changed the `main` and `chat` panels sidebar panel keys to use exported const values for reuse
* Allowed custom sidebar sections to hide their headers with the `hideSectionHeader` option
* Add a `groupSettingArray` setting on `this.siteSettings` in JS, which accepts a group site setting name
and splits it by `|` then converts the items in the array to integers, similar to the `_map` magic for ruby
group site settings
* Adds a `hidden` option for sidebar panels which prevents them from showing in separated mode and prevents
the switch button from being shown

This reverts commit 5f0bc4557f.
Through extensive internal discussion we have decided to revert
this change, as it significantly impacted moderation flow for
some Discourse site moderators, especially around "something else"
flags. We need to re-approach how flags are counted holistically,
so to that end this change is being reverted.
- Switch to `@tracked` and native getters
- Remove queryParam defaults which are awkward to work with. Instead, add `resolvedBlah` getters
- Add 'no results found' text
- Use standard 'model' key instead of a custom `setupController` method
- Remove use of `route-action`
- Remove `{{action` helper
Default queryParams in ember controllers are tricky to work with, especially when combined with the new router service. Instead, we can handle defaults ourselves
* DEV: upgrade grant badge modal to glimmer
* DEV: add unit tests for grant badge utils
* DEV: replace grant-badge-controller mixin with grant-badge-utils in admin-user-badges controller
* DEV: remove GrantBadgeController mixin
1. Use `this.` instead of `{{action}}` where applicable
2. Use `{{fn}}` instead of `@actionParam` where applicable
3. Use non-`@` versions of class/type/tabindex/aria-controls/aria-expanded
4. Remove `btn` class (it's added automatically to all DButtons)
5. Remove `type="button"` (it's the default)
6. Use `concat-class` helper
This tab doesn't really provide anything useful, and can be quite
confusing in some cases. Each plugin is already listed below, and
you can navigate to their settings from there. We want to move away
from the catch-all Plugins category for site settings. Core plugins are
not shown in this list as at 97a812f022.
This commit contains a few improvements:
* Use LinkTo instead of a button with a weird action referencing the
controller to navigate to the filtered settings for a plugin
* Add an AdminPlugin model with tracked properties and use that when
toggling the setting on/off and in the templates
* Make it so the Settings button for a plugin navigates to the correct
site setting category instead of always just going to the generic
"plugins" one if possible
Previously, we had a `showFooter` boolean on the application controller which would be set true/false in various routes by different routes/controllers. A global `routeWillChange` hook would set it `false` before every route transition, and the destination route/controller would have to set it `true` for the footer to show correctly.
This commit replaces that with a new 'declarative' system. Instead of having to set the value true/false manually, UIs which need the footer to be hidden can simply include the `{{hide-application-footer}}` helper in their template when needed. The helper/service will automatically keep track of all the current invocations of that helper, and only show the footer when there are 0 invocations.
This significantly simplifies things, and removes the need for many observers and controller injections, both of which are considered 'code smells' in modern Ember applications.
This commit makes some visual tweaks to the admin panel plugin list, and introduces functional 'toggle switches' for admins to enable/disable plugins more easily.

FEATURE: Only approved flags for post counters
* Why was this change necessary?
The counters for flagged posts in the user's profile and user index from
the admin view include flags that were rejected, ignored or pending
review. This introduces unnecessary noise. Also the flagged posts
counter in the user's profile includes custom flags which add further
noise to this signal.
* How does it address the problem?
* Modifying User#flags_received_count to return posts with only approved
standard flags
* Refactoring User#number_of_flagged_posts to alias to
User#flags_received_count
* Updating the flagged post staff counter hyperlink to navigate to a
filtered view of that user's approved flagged posts to maintain
consistency with the counter
* Adding system tests for the profile page to cover the flagged posts
staff counter
provide the ability to edit theme settings in the json editor, and also copy them as a text file so they can be pasted into another instance.
Reference: /t/65023
- Convert `admin-incoming-email` modal to component-based API
- Testing that the modal was working in local development was extremely challenging due to the need for `rejected` and `bounced` emails. Something that is not easy to stub in a local dev environment. To make this process more smooth for future developers I have added a new rake task:
```
desc "Creates sample email logs"
task "email_logs:populate" => ["db:load_config"] do |_, args|
DiscourseDev::EmailLog.populate!
end
```
That will generate fully functional email logs in development to be toyed with.

Recently we started giving admins a notice in the advice panel when their translations have become outdated due to changes in core. However, we didn't include any additional information.
This PR adds more information about the outdated translation inside the site text edit page, together with an option to dismiss the warning.
This PR adds a feature to help admins stay up-to-date with their translations. We already have protections preventing admins from problems when they update their overrides. This change adds some protection in the other direction (where translations change in core due to an upgrade) by creating a notice for admins when defaults have changed.
Terms:
- In the case where Discourse core changes the default translation, the translation override is considered "outdated".
- In the case above where interpolation keys were changed from the ones the override is using, it is considered "invalid".
- If none of the above applies, the override is considered "up to date".
How does it work?
There are a few pieces that makes this work:
- When an admin creates or updates a translation override, we store the original translation at the time of write. (This is used to detect changes later on.)
- There is a background job that runs once every day and checks for outdated and invalid overrides, and marks them as such.
- When there are any outdated or invalid overrides, a notice is shown in admin dashboard with a link to the text customization page.
Known limitations
The link from the dashboard links to the default locale text customization page. Given there might be invalid overrides in multiple languages, I'm not sure what we could do here. Consideration for future improvement.
This is the first of a number of PRs aimed at helping admins manage their translation overrides. It simply adds a list of available interpolation keys below the input field when editing an override.
It also includes custom interpolation key.
We have been struggling lately finding site settings due to 30 setting limit
This was introduced for performance reasons a while back but is no longer as
needed given that ember is faster.
Additionally searching is hard, so allow people to use fuzzy search against
setting name.
As part of another regression, we realized that the plugins tab is visible to moderators, but they cannot interact with anything inside without triggering authorization errors.
This change hides the plugin tab for non-admin users.
In some languages, labels on the site settings navigation menu
get truncated. This adds titles to menu items, so users can see
untruncated labels on hover.
Moving the `grantBadge` action out of the actions hash caused it to clash with a method of the same name from the GrantBadgeController mixin. This commit renames the action.
This commit implements many changes to topic and comments embedding. It
deprecates the class_name field from EmbeddableHost and suggests using
the className parameter. discourse_username parameter has been
deprecated and it will fetch it from embedded site from the author or
discourse-username meta.
See the updated code sample from Admin > Customize > Embedding page.
* FEATURE: Add className parameter for Discourse embed
* DEV: Hide class_name from EmbeddableHost
* DEV: Deprecate class_name field of EmbeddableHost
* FEATURE: Use either author or discourse-username meta tag
* DEV: Deprecate discourse_username parameter
* DEV: Improve embed code sample
The `tagName` argument is now deprecated. This commit uses a codemod (https://github.com/discourse/discourse-ember-codemods/tree/main/transforms/extract-plugin-outlet-tagname) to automatically remove the `@tagName` from all PluginOutlet invocations, and create a matching wrapper element so that the HTML structure is unchanged. We may want to remove some/all of these wrappers entirely in future, but that would be a riskier change which we should tackle on a case-by-case basis.
* Remove unused strings
* Remove trailing quote from string
* Remove even more unused strings (they were removed in c4e10f2a9d)
* Don't use translations in tests which are only available on server
* Use more specific translation (and fix missing translation)
1. The events table had broken styling, making each row overflow
2. It had confusing routes: `/:id` for "edit" and `/:id/events` for "show" (now it's `/:id/edit` and `/:id` respectively)
3. There previously was an unused backend action (`#edit`) - now it is used (and `web_hooks/:id/events` route has been removed)
4. There was outdated/misplaced/duplicated CSS
5. And more
* FEATURE: Show similar users when penalizing a user
Moderators will be notified if other users with the same IP address
exist before penalizing a user.
* FEATURE: Allow staff to penalize multiple users
This allows staff members to suspend or silence multiple users belonging
to the same person.
Previously if a specific plugin route was not available (e.g. there was an error loading the plugin's JS due to an ad blocker), the entire page would fail to load. This commit updates the behavior to catch this kind of issue and display a user-friendly message at the top of the screen.
Lone hbs files in the `/components` are automatically assumed to be template-only Glimmer components. The `templateOnly()` stub is only required when templates are in the `/templates/components` directory.
This PR enables the [`no-action-modifiers`](https://github.com/ember-template-lint/ember-template-lint/blob/master/docs/rule/no-action-modifiers.md) template lint rule and removes all usages of the `{{action}}` modifier in core.
In general, instances of `{{action "x"}}` have been replaced with `{{on "click" (action "x")}}`.
In many cases, such as for `a` elements, we also need to prevent default event handling to avoid unwanted side effects. While the `{{action}}` modifier internally calls `event.preventDefault()`, we need to handle these cases more explicitly. For this purpose, this PR also adds the [ember-event-helpers](https://github.com/buschtoens/ember-event-helpers) dependency so we can use the `prevent-default` handler. For instance:
```
<a href {{on "click" (prevent-default (action "x"))}}>Do X</a>
```
Note that `action` has not in general been refactored away as a helper yet. In general, all event handlers should be methods on the corresponding component and referenced directly (e.g. `{{on "click" this.doSomething}}`). However, the `action` helper is used extensively throughout the codebase and often references methods in the `actions` hash on controllers or routes. Thus this refactor will also be extensive and probably deserves a separate PR.
Note: This work was done to complement #17767 by minimizing the potential impact of the `action` modifier override, which uses private API and arguably should be replaced with an AST transform.
This is a followup to #18333, which had to be reverted because it did not account for the default treatment of modifier keys by the {{action}} modifier.
Commits:
* Enable `no-action-modifiers` template lint rule
* Replace {{action "x"}} with {{on "click" (action "x")}}
* Remove unnecessary action helper usage
* Remove ctl+click tests for user-menu
These tests now break in Chrome when used with addEventListener. As per the comment, they can probably be safely removed.
* Prevent default event handlers to avoid unwanted side effects
Uses `event.preventDefault()` in event handlers to prevent default event handling. This had been done automatically by the `action` modifier, but is not always desirable or necessary.
* Restore UserCardContents#showUser action to avoid regression
By keeping the `showUser` action, we can avoid a breaking change for plugins that rely upon it, while not interfering with the `showUser` argument that's been passed.
* Revert EditCategoryTab#selectTab -> EditCategoryTab#select
Avoid potential breaking change in themes / plugins
* Restore GroupCardContents#showGroup action to avoid regression
By keeping the `showGroup` action, we can avoid a breaking change for plugins that rely upon it, while not interfering with the `showGroup` argument that's been passed.
* Restore SecondFactorAddTotp#showSecondFactorKey action to avoid regression
By keeping the `showSecondFactorKey` action, we can avoid a breaking change for plugins that rely upon it, while not interfering with the `showSecondFactorKey` property that's maintained on the controller.

1. Replace `{{did-insert` with the builtin `{{on` modifier
2. Move the i18n call into the template
With both of those changes, there is no logic left in the backing class, so we can switch to `templateOnly()` which is significantly faster. (granted, not a big deal for a component like this, but it makes for a good demonstration)
A public key must be added to GitHub when installing private themes.
When the process happens asynchronously (for example if the admin does
not have admin permissions to the GitHub repository), installing
private themes becomes very difficult.
In this case, the Discourse admin can partially install the theme by
letting Discourse save the private key, create a placeholder theme and
give the admin a public key to be used as a deploy key. After the key
is installed, the admin can finish theme installation by pressing a
button on the theme page.
Follow up to 4d3c1ceb44, this commit
shows the SMTP response in the admin email sent list and also moves the
topic/post link into a new column. Reply key is now in its own column.
* FEATURE: Add case-sensitivity flag to watched_words
Currently, all watched words are matched case-insensitively. This flag
allows a watched word to be flagged for case-sensitive matching.
To allow allow for backwards compatibility the flag is set to false by
default.
* FEATURE: Support case-sensitive creation of Watched Words via API
Extend admin creation and upload of Watched Words to support case
sensitive flag. This lays the ground work for supporting
case-insensitive matching of Watched Words.
Support for an extra column has also been introduced for the Watched
Words upload CSV file. The new column structure is as follows:
word,replacement,case_sentive
* FEATURE: Enable case-sensitive matching of Watched Words
WordWatcher's word_matcher_regexp now returns a list of regular
expressions instead of one case-insensitive regular expression.
With the ability to flag a Watched Word as case-sensitive, an action
can have words of both sensitivities.This makes the use of the global
Regexp::IGNORECASE flag added to all words problematic.
To get around platform limitations around the use of subexpression level
switches/flags, a list of regular expressions is returned instead, one for each
case sensitivity.
Word matching has also been updated to use this list of regular expressions
instead of one.
* FEATURE: Use case-sensitive regular expressions for Watched Words
Update Watched Words regular expressions matching and processing to handle
the extra metadata which comes along with the introduction of
case-sensitive Watched Words.
This allows case-sensitive Watched Words to matched as such.
* DEV: Simplify type casting of case-sensitive flag from uploads
Use builtin semantics instead of a custom method for converting
string case flags in uploaded Watched Words to boolean.
* UX: Add case-sensitivity details to Admin Watched Words UI
Update Watched Word form to include a toggle for case-sensitivity.
This also adds support for, case-sensitive testing and matching of Watched Word
in the admin UI.
* DEV: Code improvements from review feedback
- Extract watched word regex creation out to a utility function
- Make JS array presence check more explicit and readable
* DEV: Extract Watched Word regex creation to utility function
Clean-up work from review feedback. Reduce code duplication.
* DEV: Rename word_matcher_regexp to word_matcher_regexp_list
Since a list is returned now instead of a single regular expression,
change `word_matcher_regexp` to `word_matcher_regexp_list` to better communicate
this change.
* DEV: Incorporate WordWatcher updates from upstream
Resolve conflicts and ensure apply_to_text does not remove non-word characters in matches
that aren't at the beginning of the line.
7caaee2 introduced a duplicate definition of the component JS. This likely happened because we had the template defined under `javascripts/discourse`, and the component JS defined under `javascript/admin`. This commit removes the duplicate definition, and moves the template to the admin addon
Twitter does not allow SVGs to be used for twitter:image
metadata (see https://developer.twitter.com/en/docs/twitter-for-websites/cards/overview/markup)
so we should fall back to the site logo if the image option
provided to `crawlable_meta_data` or SiteSetting.site_twitter_summary_large_image_url
is an SVG, and do not add the meta tag for twitter:image at all
if the site logo is an SVG.
Adds up and down buttons next to the inputs of value lists when there is more than 1 item present. This helps to re-order the items in the value lists if necessary.
An admin could search for all screened ip addresses in a block by
using wildcards. 192.168.* returned all IPs in range 192.168.0.0/16.
This feature allows admins to search for a single IP address in all
screened IP blocks. 192.168.0.1 returns all IP blocks that match it,
for example 192.168.0.0/16.
* FEATURE: Remove roll up button for screened IPs
* FIX: Match more specific screened IP address first
This commit should be a no-op for all existing core outlets. Outlets which are introduced by themes/plugins may see a change in behavior, and should follow the steps below if they want to maintain their previous behavior.
`tagName="" connectorTagName=""` is almost always the correct choice for plugin outlets. 40eba8cd introduced a `noTags=true` shortcut which achieved this, and left a comment saying it should be the future default. This commit does exactly that. To avoid any breaking changes for plugins, all existing plugin outlets have been reviewed and adjusted by following this logic:
1) If `noTags=true`, remove the `noTags` parameter, and do not complete any further steps
2) If `tagName` is not specified, set `tagName="span"` (the previous default)
3) If `connectorTagName` is not specified, set `selectorTagName="div"` (the previous default)
4) If `tagName=""`, remove it
5) If `connectorTagName=""`, remove it
The updates were accomplished with the help of a ruby script:
```ruby
def removeAttr(tag, attribute)
tag = tag.sub /\s#{attribute}="?\w*"? /, " "
tag = tag.sub /\s#{attribute}="?\w*"?}}/, "}}"
tag = tag.sub /^\s*#{attribute}="?\w*"?\n/, ""
tag
end
files = Dir.glob("app/assets/javascripts/**/*.hbs")
puts "Checking #{files.count} files..."
files.each do |f|
content = File.read(f)
count = 0
edits = 0
content.gsub!(/{{\s*plugin-outlet.*?}}/m) do |match|
count += 1
result = match
noTags = result.include?("noTags=true")
tagName = result[/tagName="(\w*)"/, 1]
connectorTagName = result[/connectorTagName="(\w*)"/, 1]
if noTags
result = removeAttr(result, "noTags")
else
if connectorTagName == ""
result = removeAttr(result, "connectorTagName")
elsif connectorTagName.nil?
result = result.sub(/name="[\w-]+"/) { |m| "#{m} connectorTagName=\"div\"" }
end
if tagName == ""
result = removeAttr(result, "tagName")
elsif tagName.nil?
result = result.sub(/name="[\w-]+"/) { |m| "#{m} tagName=\"span\"" }
end
end
edits += 1 if match != result
result
end
puts "#{count} outlets, #{edits} edited -> #{f}"
File.write(f, content)
end
```
This commit adds a check that runs regularly as per
2d68e5d942 which tests the
credentials of groups with SMTP or IMAP enabled. If any issues
are found with those credentials a high priority problem is added to the
admin dashboard.
This commit also formats the admin dashboard differently if
there are high priority problems, bringing them to the top of
the list and highlighting them.
The problem will be cleared if the issue is fixed before the next
problem check, or if the group's settings are updated with a valid
credential.
This commit removes the enable_experimental_backup_uploader site
setting and the flags in backups-index.hbs to make the uppy
backup uploader the main one from now on.
A follow-up commit will delete the old backup uploader code and
also remove resumable.js from the project.
This commit introduces scheduled problem checks for the admin dashboard, which are long running or otherwise cumbersome problem checks that will be run every 10 minutes rather than every time the dashboard is loaded. If these scheduled checks add a problem, the problem will remain until it is cleared or until the scheduled job runs again.
An example of a check that should be scheduled is validating credentials against an external provider.
This commit also introduces the concept of a `priority` to the problems generated by `AdminDashboardData` and the scheduled checks. This is `low` by default, and can be set to `high`, but this commit does not change any part of the UI with this information, only adds a CSS class.
I will be making a follow up PR to check group SMTP credentials.
In the composer, we already only allow for S3 multipart uploads
if enable_direct_s3_uploads is true, so in the backups uploader
that is based on Uppy we want to do the same thing. In future
if self-hosters need some way to not use S3 multipart in these
scenarios for whatever reason we can revisit this then (which
should be as simple as adding a enable_multipart_s3_uploads site
setting).
This takes the uppy chunking algorithm and combines it with some
form submission from resumable.js for parity with the current
backup controller to make local backup uploads work with uppy.
We can then use this to replace the resumable-upload component
and the resumable.js library from our codebase, once stable.
This is disabled by default, so people using local backups will not
be affected. The enable_experimental_backup_uploader site setting
must be enabled for this to work.
