... wasn't working because it wasn't storing the proper "action" value.
Issue was that we were using the "action" parameter which is being used by Rails to determine which controller action to call.
We need to use the "action_key" parameter instead.
At the moment, there is no way to create a group of related watched words together. If a user needed a set of words to be created together, they'll have to create them individually one at a time.
This change attempts to allow related watched words to be created as a group. The idea here is to have a list of words be tied together via a common `WatchedWordGroup` record. Given a list of words, a `WatchedWordGroup` record is created and assigned to each `WatchedWord` record. The existing WatchedWord creation behaviour remains largely unchanged.

This commit introduces a few changes as a result of
customer issues with finding why a topic was relisted.
In one case, if a user edited the OP of a topic that was
unlisted and hidden because of too many flags, the topic
would get relisted by directly changing topic.visible,
instead of going via TopicStatusUpdater.
To improve tracking we:
* Introduce a visibility_reason_id to topic which functions
in a similar way to hidden_reason_id on post, this column is
set from the various places we change topic visibility
* Fix Post#unhide! which was directly modifying topic.visible,
instead we use TopicStatusUpdater which sets visibility_reason_id
and also makes a small action post
* Show the reason topic visibility changed when hovering the
unlisted icon in topic status on topic titles
Selecting the +subcategories option does not work sometimes when "lazy
load categories" is enabled because the subcategories may not be
fetched. This ensures that subcategories are loaded by requesting them
before being used.
Our 'page_view_crawler' / 'page_view_anon' metrics are based purely on the User Agent sent by clients. This means that 'badly behaved' bots which are imitating real user agents are counted towards 'anon' page views.
This commit introduces a new method of tracking visitors. When an initial HTML request is made, we assume it is a 'non-browser' request (i.e. a bot). Then, once the JS application has booted, we notify the server to count it as a 'browser' request. This reliance on a JavaScript-capable browser matches up more closely to dedicated analytics systems like Google Analytics.
Existing data collection and graphs are unchanged. Data collected via the new technique is available in a new 'experimental' report.
Fixes two issues:
- frontend was reloading the page when clicking-to-remove avatar
- backend wasn't allowing resetting the setting by deleting all avatars
For better performances when listing all the API keys.
Loading all the "api key scopes" is slow and not required when showing the list of all the api keys.
- Run the CSP-nonce-related middlewares on the generated response
- Fix the readonly mode checking to avoid empty strings being passed (the `check_readonly_mode` before_action will not execute in the case of these re-dispatched exceptions)
- Move the BlockRequestsMiddleware cookie-setting to the middleware, so that it is included even for unusual HTML responses like these exceptions
Full text search does not return ideal results for category dropdown.
Usually, in category dropdowns we want to search for categories as we
type. For example, while typing "theme", the dropdown should show
intermediary results for "t", "th", "the", "them" and finally "theme".
For some of these substrings (like "the"), full text search does not
return any results, which leads to an unpleasant user experience.
The breadcrumbs were updated everytime there were changes to the
categories which was not efficient and caused unnecessary rerendering
of the CategoryDrop elements when "lazy load categories" is enabled.
This commit also ensures that all category fields are serialized for
ancestors too for the categories#search endpoint.
Include categories when fetching admin/web_hooks and make
'extras' more useful. 'extras' is the mechanism we use to provide
context for rest objects.
However, previously:
* When you fetched many objects, extras was only set on the ResultSet,
not on each object,
* If you need derived data from extras, there wasn't a sensible place to
put this code. Now, you can create an 'ExtrasClass' static field on
your rest model and this class will be used for your extras data,
When lazy load categories is enabled, categories should be loaded with
user activity items and drafts because the categories may not be
preloaded on the client side.
Using around_action means `add_early_hint_header` is in the stack for every request, and gets included in the backtrace of any errors.
We can manage with an after_action instead, which avoids adding to the stack depth (and avoids people blaming me for unrelated application errors 😉)
We will be collecting the logo URL and the site's default locale values along with existing basic details to display the site on the Discourse Discover listing page. It will be included only if the site is opted-in by enabling the "`include_in_discourse_discover`" site setting.
Also, we no longer going to use `about.json` and `site/statistics.json` endpoints retrieve these data. We will be using only the `site/basic-info.json` endpoint.
Plugins that are hidden or disabled aren't shown in the plugins list at `/admin/plugins` because they cannot be changed. However, the `#show` route doesn't check for the plugin's state and responds with 200 and the plugin's info even if the plugin is hidden or disabled. This commit makes the `#show` route respond with 404 if the plugin is hidden or disabled.
Why this change?
Before this change, the validation error message shown to the user when
saving a theme objects setting is very cryptic. This commit changes the
validation error messages to be displayed on top of the editor instead.
Note that I don't think this way of displaying is the ideal state we
want to get to but given the time we have this will do for now.
This commit removes the 'experimental_preconnect_link_header' site setting, and the 'preload_link_header' site setting, and introduces two new global settings: early_hint_header_mode and early_hint_header_name.
We don't actually send 103 Early Hint responses from Discourse. However, upstream proxies can be configured to cache a response header from the app and use that to send an Early Hint response to future clients.
- `early_hint_header_mode` specifies the mode for the early hint header. Can be nil (disabled), "preconnect" (lists just CDN domains) or "preload" (lists all assets).
- `early_hint_header_name` specifies which header name to use for the early hint. Defaults to "Link", but can be changed to support different proxy mechanisms.
Why this change?
Previously, we were preloading the necessary metadata for
`adminCustomizeThemes.show.schema` route in the
`adminCustomizeThemes.show` route. This is wasteful because we're
loading data upfront when the objects setting editor may not be used.
This change also lays the ground work for a future commit where we need
to be shipping down additional metadata which may further add to the
payload.
Previously, when crawlers triggered a Discourse::InvalidAccess exception, they would be served the full Ember SPA. The SPA is not optimized for crawling, and so this is likely to cause problems for sites. This issue is particularly problematic when user profiles are hidden from the public via the `hide_user_profiles_from_public` setting, because the crawler would end up being 'soft-redirected' to the homepage in the SPA.
Why this change?
In https://web.dev/articles/preconnect-and-dns-prefetch, it describes
how hinting to the browser to preconnect to domains which we will
eventually use the connection for can help improve the time it takes to
load a page.
We are putting this behind an experimental flag so that we can test and
profile this in a production environment.
What does this change introduce?
Introduce a hidden experimental `experimental_preconnect_link_header`
site setting which when enabled will add the `preconnect` and
`dns-prefetch` resource hints to the response headers for full page load
requests.
This commit makes it so the site settings filter controls and
the list of settings input editors themselves can be used elsewhere
in the admin UI outside of /admin/site_settings
This allows us to provide more targeted groups of settings in different
UI areas where it makes sense to provide them, such as on plugin pages.
You could open a single page for a plugin where you can see information
about that plugin, change settings, and configure it with custom UIs
in the one place.
In future we will do this in "config areas" for other parts of the
admin UI.
This commit operates at three levels of abstraction:
1. We want to prevent user history rows from being unbounded in size.
This commit adds rails validations to limit the sizes of columns on
user_histories,
2. However, we don't want to prevent certain actions from being
completed if these columns are too long. In those cases, we truncate
the values that are given and store the truncated versions,
3. For endpoints that perform staff actions, we can further control
what is permitted by explicitly validating the params that are given
before attempting the action,
With the new admin sidebar restructure, we have a link to "Installed plugins". We would like to ensure that when the admin is searching for a plugin name like "akismet" or "automation" this link will be visible. Also when entering the plugins page, related plugins should be highlighted.
This commit adds new plugin show routes (`/admin/plugins/:plugin_id`) as we move
towards every plugin having a consistent UI/landing page.
As part of this, we are introducing a consistent way for plugins
to show an inner sidebar in their config page, via a new plugin
API `register_admin_config_nav_routes`
This accepts an array of links with a label/text, and an
ember route. Once this commit is merged we can start the process
of conforming other plugins to follow this pattern, as well
as supporting a single-page version of this for simpler plugins
that don't require an inner sidebar.

Previously, if the sso= payload was invalid Base64, but signed correctly, there would be no useful log or error. This commit improves things by:
- moving the base64 check before the signature checking so that it's properly surfaced
- split the ParseError exception into PayloadParseError and SignatureError
- add user-facing errors for both of those
- add/improve spec for both
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.
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.
Users can hide their public profile and presence information by checking
“Hide my public profile and presence features” on the
`u/{username}/preferences/interface` page. In that case, we also don't
want to return user status from the server.
This work has been started in https://github.com/discourse/discourse/pull/23946.
The current PR fixes all the remaining places in Core.
Note that the actual fix is quite simple – a5802f484d.
But we had a fair amount of duplication in the code responsible for
the user status serialization, so I had to dry that up first. The refactoring
as well as adding some additional tests is the main part of this PR.
Now forums can enroll their sites to be showcased in the Discourse [Discover](https://discourse.org/discover) directory. Once they enable the site setting `include_in_discourse_discover` to enroll their forum the `CallDiscourseHub` job will ping the `api.discourse.org/api/discover/enroll` endpoint. Then the Discourse Hub will fetch the basic details from the forum and add it to the review queue. If the site is approved then the forum details will be displayed in the `/discover` page.
This commit moves some code out of UploadController#show_secure
so it can be reused in other controllers if a secure upload
needs to have permission checks run.
This commit adds another plugin modifier related to post
actions, similar to ae24e04a5e.
This will be used to exclude users who liked _and_ reacted to
the post, since now in discourse-reactions we make a Like when
a user reacts too. This will affect the display of the post footer.
This commit is the first of a series of commits that will allow themes to define complex settings types by declaring a schema of the setting structure that Discourse core will use to build a UI for the setting automatically. We implement the navigation logic and support for multiple levels of nesting in this commit and we'll continue building this new system gradually in future commits.
Internal topic: t/116870.
When making sensitive changes to an account (adding 2FA or passkeys), we
require users to confirm their password. This is to prevent an attacker
from adding 2FA to an account they have access to.
However, on newly created accounts, we should not require this, it's an
extra step and it doesn't provide extra security (since the account was
just created). This commit makes it so that we don't require session
confirmation for accounts created less than 5 minutes ago.
This would allow a theme component (or an API call) to reset the bump
date of a topic to a given post's created_at date.
I picked `post_id` as the parameter here because it provides a bit of
extra protection against accidentally resetting the bump date to a date
that doesn't make sense.
This commit includes several changes to make hashtags work when "lazy
load categories" is enabled. The previous hashtag implementation use the
category colors CSS variables, but these are not defined when the site
setting is enabled because categories are no longer preloaded.
This commit implements two fundamental changes:
1. load colors together with the other hashtag information
2. load cooked hashtag data asynchronously
The first change is implemented by adding "colors" to the HashtagItem
model. It is a list because two colors are returned for subcategories:
the color of the parent category and subcategory.
The second change is implemented on the server-side in a new route
/hashtags/by-ids and on the client side by loading previously unseen
hashtags, generating the CSS on the fly and injecting it into the page.
There have been minimal changes outside of these two fundamental ones,
but a refactoring will be coming soon to reuse as much of the code
and maybe favor use of `style` rather than injecting CSS into the page,
which can lead to page rerenders and indefinite grow of the styles.
When we show the links to installed plugins in the admin
sidebar (for plugins that have custom admin routes) we were
previously only doing this if you opened /admin, not if you
navigated there from the main forum. We should just always
preload this data if the user is admin.
This commit also changes `admin_sidebar_enabled_groups` to
not be sent to the client as part of ongoing efforts to
not check groups on the client, since not all a user's groups
may be serialized.
These routes were previously rendered using Rails, and had a fairly fragile 2fa implementation in vanilla-js. This commit refactors the routes to be handled in the Ember app, removes the custom vanilla-js bundles, and leans on our centralized 2fa implementation. It also introduces a set of system specs for the behavior.
In a handful of situations, we need to verify a user's 2fa credentials before `current_user` is assigned. For example: login, email_login and change-email confirmation. This commit adds an explicit `target_user:` parameter to the centralized 2fa system so that it can be used for those situations.
For safety and clarity, this new parameter only works for anon. If some user is logged in, and target_user is set to a different user, an exception will be raised.
We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_level_for_user_api_key site setting to user_api_key_allowed_groups.
This isn't used by any of our plugins or themes, so very little fallout.
This introduces a new experimental hot sort ordering.
It attempts to float top conversations by first prioritizing a topics with lots of recent activity (likes and users responding)
The schedule that updates hot topics is disabled unless the hidden site setting: `experimental_hot_topics` is enabled.
You can control "decay" with `hot_topic_gravity` and `recency` with `hot_topics_recent_days`
Data is stored in the new `topic_hot_scores` table and you can check it out on the `/hot` route once
enabled.

* FIX: respect creation date when paginating group activity posts
There are scenarios where the chronological order of posts doesn't match the order of their IDs. For instance, when moving the first post from one topic or PM to another, a new post (with a higher ID) will be created, but it will retain the original creation time.
This PR changes the group activity page and endpoint to paginate posts using created_at instead of relying on ID ordering.
Why this change?
Importing theme with the `bundle` params is used mainly by
`discourse_theme` CLI in the development environment. However, we do not
want migrations to automatically run in the development environment
and instead want the developer to be intentional about running theme
migrations. As such, this commit adds support for a
`skip_migrations` param when importing a theme with the `bundle` params.
This commit also adds a `migrated` attribute for migrations theme fields
to indicate whether a migrations theme field has been migrated or not.

While looking through various Rails issues related to the error above, I
came across https://github.com/rails/rails/pull/27647 which is a fix to
fully initialize routes before the first request is handled. However,
the routes are only fully initialize only if `config.eager_load` is set
to `true`. There is no reason why `config.eager_load` shouldn't be `true` in the
CI environment and this is what a new Rails 7.1 app is generated with.
What does this change do?
Enable `config.eager_load` when `env["CI"]` is present
When updating the position of a category, the server correctly updates the position in the database, but the response sent back to the client still contains the old position, causing it to "flip back" in the UI when saving. Only reloading the page will reveal the new, correct value.
The Positionable concern correctly positions the record and updates the database, but we don't assign the new position to the already instantiated model.
This change just assigns self.position after the database update. 😎
This changes the Plugins link in the admin sidebar to
be a section instead, which then shows all enabled plugin
admin routes (which are custom routes some plugins e.g.
chat define).
This is done via adding some special preloaded data for
all controllers based on AdminController, and also specifically
on Admin::PluginsController, to have the routes loaded without
additional requests on page load.
We just use a cog for all the route icons for now...we don't
have anything better.
Meta topic: https://meta.discourse.org/t/reseting-robots-txt-override-doesnt-seem-to-work-as-expected/287880?u=osama
Discourse provides a default version for `/robots.txt` which can be customized by admins in `/admin/customize/robots`. In that page, there's a button to reset back to the default version that Discourse provides. However, there's currently a bug with the reset button where the content appears to change to some HTML document instead of the default `robots.txt` version when clicking the button. Refreshing the page shows the true/correct content of `robots.txt` which is the default version, so the reset button actually works but there's a display problem.
What causes this display problem is that we use Rails' `render_to_string` method to generate the default content for `robots.txt` from the template, and what we get from that method is the `robots.txt` content wrapped in the application layout. To fix this issue, we need to pass `layout: false` to the `render_to_string` method so that it renders the template without any layouts.
Why this change?
This is part of our efforts to harden the security of the Discourse
application. Setting the `CROSS_ORIGIN_OPENER_POLICY` header to `same-origin-allow-popups`
by default makes the application safer. We have opted to make this a
hidden site setting because most admins will never have to care about
this setting so we're are opting not to show it. If they do have to
change it, they can still do so by setting the
`DISCOURSE_CROSS_ORIGIN_OPENER_POLICY` env.
Settings that are using the new `file_size_restriction` types like the
`max_image_size_kb` setting need to have their values saved as integers.
This was a recent regression in 00209f03e6
that caused these values to be saved as strings.
This change also removes negatives from the validation regex because
file sizes can't be negative anyways.

When `lazy_load_categories` is enabled, the categories are no longer
preloaded in the `Site` object, but instead they are being requested
on a need basis.
The categories page still loaded all categories at once, which was not
ideal for sites with many categories because ti would take a lot of
time to build and parse the response.
This commit adds pagination to the categories page using the LoadMore
helper. As the user scrolls through the categories page, more categories
are requested from the server and appended to the page.
<!-- NOTE: All pull requests should have tests (rspec in Ruby, qunit in JavaScript). If your code does not include test coverage, please include an explanation of why it was omitted. -->
A lot of work has been put in the select kits used for selecting
categories: CategorySelector, CategoryChooser, CategoryDrop, however
they still do not work as expected when these selectors already have
values set, because the category were still looked up in the list of
categories stored on the client-side Categrories.list().
This PR fixes that by looking up the categories when the selector is
initialized. This required altering the /categories/find.json endpoint
to accept a list of IDs that need to be looked up. The API is called
using Category.asyncFindByIds on the client-side.
CategorySelector was also updated to receive a list of category IDs as
attribute, instead of the list of categories, because the list of
categories may have not been loaded.
During this development, I noticed that SiteCategorySerializer did not
serializer all fields (such as permission and notification_level)
which are not a property of category, but a property of the relationship
between users and categories. To make this more efficient, the
preload_user_fields! method was implemented that can be used to
preload these attributes for a user and a list of categories.
I took the wrong approach here, need to rethink.

There will soon be additional login_required checks
for Guardian, and the intent of many checks by automated
systems is better fulfilled by using BasicUser, which
simulates a logged in TL0 forum user, rather than an
anon user.
In some cases the use of anon still makes sense (e.g.
anonymous_cache), and in that case the more explicit
`Guardian.anon_user` is used
The category drop was rerendered after every category async change
because it updated the categories list. This is not necessary and
categories can be referenced indirectly by ID instead.
Currently to use a limit in the notifications index, you have to also pass recent: true as a param.
This PR:
Adds optional limit param to be used in the notifications query, regardless of the presence of recent
Raises the max limit of the response with recent present from 50 -> 60. It is super weird we have a hard-limit of 50 before with recent param, and 60 without the param.
We ask users to confirm their session if they are making a sensitive
action, such as adding/updating second factors or passkeys. This
commit adds the ability to confirm sessions with passkeys as an option
to the password confirmation.
Previously, the app HTML served by the Ember-CLI proxy was generated based on a 'bootstrap json' payload generated by Rails. This inevitably leads to differences between the Rails HTML and the Ember-CLI HTML.
This commit overhauls our proxying strategy. Now, we totally ignore the ember-cli `index.html` file. Instead, we take the full HTML from Rails and surgically replace script URLs based on a `data-discourse-entrypoint` attribute. This should be faster (only one request to Rails), more robust, and less confusing for developers.
There is an edge case where the following occurs:
1. The user sets a bookmark reminder on a post/topic
2. The post/topic is changed to a PM before or after the reminder
fires, and the notification remains unread by the user
3. The user opens their bookmark reminder notification list
and they can still see the notification even though they cannot
access the topic anymore
There is a very low chance for information leaking here, since
the only thing that could be exposed is the topic title if it
changes to something sensitive.
This commit filters the bookmark unread notifications by using
the bookmarkable can_see? methods and also prevents sending
reminder notifications for bookmarks the user can no longer see.
Switches to using a dialog to confirm a session (i.e. sudo mode for
account changes where we want to be extra sure the current user is who
they say they are) to match what we do with passkeys.
When Discourse first introduced brotli support, reverse-proxy/CDN support for passing through the accept-encoding header to our NGINX server was very poor. Therefore, a separate `/brotli_assets/...` path was introduced to serve the brotli assets. This worked well, but introduces additional complexity and inconsistencies.
Nowadays, Brotli encoding is well supported, so we don't need the separate paths any more. Requests can be routed to the asset `.js` URLs, and NGINX will serve the brotli/gzip version of the asset automatically.
This commit introduces a new feature that allows theme developers to manage the transformation of theme settings over time. Similar to Rails migrations, the theme settings migration system enables developers to write and execute migrations for theme settings, ensuring a smooth transition when changes are required in the format or structure of setting values.
Example use cases for the theme settings migration system:
1. Renaming a theme setting.
2. Changing the data type of a theme setting (e.g., transforming a string setting containing comma-separated values into a proper list setting).
3. Altering the format of data stored in a theme setting.
All of these use cases and more are now possible while preserving theme setting values for sites that have already modified their theme settings.
Usage:
1. Create a top-level directory called `migrations` in your theme/component, and then within the `migrations` directory create another directory called `settings`.
2. Inside the `migrations/settings` directory, create a JavaScript file using the format `XXXX-some-name.js`, where `XXXX` is a unique 4-digit number, and `some-name` is a descriptor of your choice that describes the migration.
3. Within the JavaScript file, define and export (as the default) a function called `migrate`. This function will receive a `Map` object and must also return a `Map` object (it's acceptable to return the same `Map` object that the function received).
4. The `Map` object received by the `migrate` function will include settings that have been overridden or changed by site administrators. Settings that have never been changed from the default will not be included.
5. The keys and values contained in the `Map` object that the `migrate` function returns will replace all the currently changed settings of the theme.
6. Migrations are executed in numerical order based on the XXXX segment in the migration filenames. For instance, `0001-some-migration.js` will be executed before `0002-another-migration.js`.
Here's a complete example migration script that renames a setting from `setting_with_old_name` to `setting_with_new_name`:

Internal topic: t/109980
Two changes were introduced:
1. Reorder links on sidebar section is removed. Clicking and holding the mouse for 250ms was unintuitive;
2. Fixed bugs when reorder is done in edit modal.
As part of #23816, which sought to strip out thousand separators, we also accidentally strip out signs. This is making it impossible to disable some settings which require a -1 to disable. Instead of stripping non-digits, strip anything that isn't a sign or a digit.
Why this change?
When the URL `/t/1234?preview_theme_id=21` is loaded, we redirect to
`/t/<topic slug>/1234` stripping the `preview_theme_id` query params.
What does this change do?
This change builds on 61248652cd and
simply adds the `preview_theme_id` query param when redirecting.
* FIX: Secure upload post processing race condition
This commit fixes a couple of issues.
A little background -- when uploads are created in the composer
for posts, regardless of whether the upload will eventually be
marked secure or not, if secure_uploads is enabled we always mark
the upload secure at first. This is so the upload is by default
protected, regardless of post type (regular or PM) or category.
This was causing issues in some rare occasions though because
of the order of operations of our post creation and processing
pipeline. When creating a post, we enqueue a sidekiq job to
post-process the post which does various things including
converting images to lightboxes. We were also enqueuing a job
to update the secure status for all uploads in that post.
Sometimes the secure status job would run before the post process
job, marking uploads as _not secure_ in the background and changing
their ACL before the post processor ran, which meant the users
would see a broken image in their posts. This commit fixes that issue
by always running the upload security changes inline _within_ the
cooked_post_processor job.
The other issue was that the lightbox wrapper link for images in
the post would end up with a URL like this:
```
href="/secure-uploads/original/2X/4/4e1f00a40b6c952198bbdacae383ba77932fc542.jpeg"
```
Since we weren't actually using the `upload.url` to pass to
`UrlHelper.cook_url` here, we weren't converting this href to the CDN
URL if the post was not in a secure context (the UrlHelper does not
know how to convert a secure-uploads URL to a CDN one). Now we
always end up with the correct lightbox href. This was less of an issue
than the other one, since the secure-uploads URL works even when the
upload has become non-secure, but it was a good inconsistency to fix
anyway.
This commit introduces a new endpoint to search categories and uses it
instead of the categories map that is preloaded using SiteSerializer.
This feature is enabled only when the hidden site setting
lazy_load_categories is enabled and should be used only on sites with
many categories.
Why this change?
The `PostsController#create` action allows arbitrary topic custom fields
to be set by any user that can create a topic. Without any restrictions,
this opens us up to potential security issues where plugins may be using
topic custom fields in security sensitive areas.
What does this change do?
1. This change introduces the `register_editable_topic_custom_field` plugin
API which allows plugins to register topic custom fields that are
editable either by staff users only or all users. The registered
editable topic custom fields are stored in `DiscoursePluginRegistry` and
is called by a new method `Topic#editable_custom_fields` which is then
used in the `PostsController#create` controller action. When an unpermitted custom fields is present in the `meta_data` params,
a 400 response code is returned.
2. Removes all reference to `meta_data` on a topic as it is confusing
since we actually mean topic custom fields instead.
This commit adds a new Revise... action that can be taken
for queued post reviewables. This will open a modal where
the user can select a Reason from a preconfigured list
(or by choosing Other..., a custom reason) and provide feedback
to the user about their post.
The post will be rejected still, but a PM will also be sent to
the user so they have an opportunity to improve their post when
they resubmit it.
This is part 2 (of 3) for passkeys support.
This adds a hidden site setting plus routes and controller actions.
1. registering passkeys
Passkeys are registered in a two-step process. First, `create_passkey`
returns details for the browser to create a passkey. This includes
- a challenge
- the relying party ID and Origin
- the user's secure identifier
- the supported algorithms
- the user's existing passkeys (if any)
Then the browser creates a key with this information, and submits it to
the server via `register_passkey`.
2. authenticating passkeys
A similar process happens here as well. First, a challenge is created
and sent to the browser. Then the browser makes a public key credential
and submits it to the server via `passkey_auth_perform`.
3. renaming/deleting passkeys
These routes allow changing the name of a key and deleting it.
4. checking if session is trusted for sensitive actions
Since a passkey is a password replacement, we want to make sure to confirm the user's identity before allowing adding/deleting passkeys. The u/trusted-session GET route returns success if user has confirmed their session (and failed if user hasn't). In the frontend (in the next PR), we're using these routes to show the password confirmation screen.
The `/u/confirm-session` route allows the user to confirm their session with a password. The latter route's functionality already existed in core, under the 2FA flow, but it has been abstracted into its own here so it can be used independently.

When a user creates or edits a post, we already were updating
the security of uploads in the post based on site settings and
their access control post, which is important since these uploads
may be switched from secure/not secure based on configuration.
The `with_secure_uploads?` method on a post is used to determine
whether to use the secure-uploads URL for all uploads in the post,
regardless of their individual security, so if this is false and
some of the posts are still secure when rebaking, we end up with
broken URLs.
This commit just makes it so rebaking via the UI also re-evaluates
upload security so that when the post is loaded again after processing,
all of the uploads have the correct security.
Why this change?
Back in May 17 2023 along with the release of Discourse 3.1, we announced
on meta that the legacy hamburger dropdown navigation menu is
deprecated and will be dropped in Discourse 3.2. This is the link to the announcement
on meta: https://meta.discourse.org/t/removing-the-legacy-hamburger-navigation-menu-option/265274
## What does this change do?
This change removes the `legacy` option from the `navigation_menu` site
setting and migrates existing sites on the `legacy` option to the
`header dropdown` option.
All references to the `legacy` option in code and tests have been
removed as well.
Currently, if you set an integer site setting in the admin interface and include thousands separators, you will silently configure the wrong value.
This PR replaces TextField inputs for integer site settings with NumberField. It also cleans the numeric input of any non-digits in the backend in case any separators make it through.
This is part 1 of 3, split up of PR #23529. This PR refactors the
webauthn code to support passkey authentication/registration.
Passkeys aren't used yet, that is coming in PRs 2 and 3.

This commit adds support for an optional `prompt` parameter in the
payload of the /session/sso_provider endpoint. If an SSO Consumer
adds a `prompt=none` parameter to the encoded/signed `sso` payload,
then Discourse will avoid trying to login a not-logged-in user:
* If the user is already logged in, Discourse will immediately
redirect back to the Consumer with the user's credentials in a
signed payload, as usual.
* If the user is not logged in, Discourse will immediately redirect
back to the Consumer with a signed payload bearing the parameter
`failed=true`.
This allows the SSO Consumer to simply test whether or not a user is
logged in, without forcing the user to try to log in. This is useful
when the SSO Consumer allows both anonymous and authenticated access.
(E.g., users that are already logged-in to Discourse can be seamlessly
logged-in to the Consumer site, and anonymous users can remain
anonymous until they explicitly ask to log in.)
This feature is similar to the `prompt=none` functionality in an
OpenID Connect Authentication Request; see
https://openid.net/specs/openid-connect-core-1_0.html#AuthRequest
Some sites have a large number of categories and fetching the category
IDs or category topic IDs just to build another query can take a long
time or resources (i.e. memory).
* FIX: Return 403 instead of redirect on username routes when hidding profiles
* Updated raised error to better reflect the problem to the user
* implemented suggested changes
Previously, a "`some_not_allowed`" warning message was appeared in composer even when all the users mentioned via group are already invited to the private message directly or via other groups.
The hidden site setting max_drafts_per_user defaults to 10_000 drafts per user.
The longest key should be "topic_<MAX_BIG_INT>" which is 25 characters.
In #20135 we prevented invalid inputs from being accepted in category setting form fields on the front-end. We didn't do anything on the back-end at that time, because we were still discussing which path we wanted to take. Eventually we decided we want to move this to a new CategorySetting model.
This PR moves the require_topic_approval and require_reply_approval from custom fields to the new CategorySetting model.
This PR is nearly identical to #20580, which migrated num_auto_bump_daily, but since these are slightly more sensitive, they are moved after the previous one is verified.
Previous to this change when both `normalize_emails` and `hide_email_address_taken`
is enabled the expected `account_exists` email was only sent on exact email
matches.
This expands it so it also sends an email to the canonical email owner.
Why this change?
Currently, we do not have an easy way to test themes and theme components
using Rails system tests. While we support QUnit acceptance tests for
themes and theme components, QUnit acceptance tests stubs out the server
and setting up the fixtures for server responses is difficult and can lead to a
frustrating experience. System tests on the other hand allow authors to
set up the test fixtures using our fabricator system which is much
easier to use.
What does this change do?
In order for us to allow authors to run system tests with their themes
installed, we are adding a `upload_theme` helper that is made available
when writing system tests. The `upload_theme` helper requires a single
`directory` parameter where `directory` is the directory of the theme
locally and returns a `Theme` record.
Until now, we have allowed testing themes in production environments via `/theme-qunit`. This was made possible by hacking the ember-cli build so that it would create the `tests.js` bundle in production. However, this is fundamentally problematic because a number of test-specific things are still optimized out of the Ember build in production mode. It also makes asset compilation significantly slower, and makes it more difficult for us to update our build pipeline (e.g. to introduce Embroider).
This commit removes the ability to run qunit tests in production builds of the JS app when the Embdroider flag is enabled. If a production instance of Discourse exists exclusively for the development of themes (e.g. discourse.theme-creator.io) then they can add `EMBER_ENV: development` to their `app.yml` file. This will build the entire app in development mode, and has a significant performance impact. This must not be used for real production sites.
This commit also refactors many of the request specs into system specs. This means that the tests are guaranteed to have Ember assets built, and is also a better end-to-end test than simply checking for the presence of certain `<script>` tags in the HTML.
We're seeing a large number of log noise from this endpoint due to malicious scanners that are trying to send clever params and seeing if they can break something.
This change simply rescues any NoMethodError during parameter parsing and re-raises a Discourse::InvalidParameters exception, which will be caught and render a 400.
They're both constant per-instance values, there is no need to store them
in the session. This also makes the code a bit more readable by moving
the `session_challenge_key` method up to the `DiscourseWebauthn` module.
Why this change?
As part of our ongoing efforts to security harden the Discourse
application, we are adding the `cross_origin_opener_policy_header` site setting
which allows the `Cross-Origin-Opener-Policy` response header to be set on requests
that preloads the Discourse application. In more technical terms, only
GET requests that are not json or xhr will have the response header set.
The `cross_origin_opener_policy_header` site setting is hidden for now
for testing purposes and will either be released as a public site
setting or be remove if we decide to be opinionated and ship a default
for the `Cross-Origin-Opener-Policy` response header.
Streaming doesn't work for anonymous users because we scope updates to the current user. Since they can only see cached summaries, we can skip the streaming parameter and update it directly with the ajax response.
`ReviewableQueuedPost` got refactored a while back to use the more
appropriate `target_created_by` for the user of the post being queued
instead of `created_by`. The change was not extended to the `DELETE
/review/:id` endpoint leading to error responses for a user attempting
to deleting their own queued post.
This fix extends the `Reviewable` lookup implementation in
`ReviewablesController#destroy` and Guardian implementation to account
for this change.
When we receive the stream parameter, we'll queue a job that periodically publishes partial updates, and after the summarization finishes, a final one with the completed version, plus metadata.
`summary-box` listens to these updates via MessageBus, and updates state accordingly.
This commit removes any logic in the app and in specs around
enable_experimental_hashtag_autocomplete and deletes some
old category hashtag code that is no longer necessary.
It also adds a `slug_ref` category instance method, which
will generate a reference like `parent:child` for a category,
with an optional depth, which hashtags use. Also refactors
PostRevisor which was using CategoryHashtagDataSource directly
which is a no-no.
Deletes the old hashtag markdown rule as well.
In #20135 we prevented invalid inputs from being accepted in category setting form fields on the front-end. We didn't do anything on the back-end at that time, because we were still discussing which path we wanted to take. Eventually we decided we want to move this to a new CategorySetting model.
This PR moves the num_auto_bump_daily from custom fields to the new CategorySetting model.
In addition it sets the default value to 0, which exhibits the same behaviour as when the value is NULL.
This is a similar fix to 32d4810e2b
Why this change?
Prior to this change, there is a bug in `TopicsController#bulk`
where it does not dismiss new unred posts in sub-subcategories when the
`category_id` and `include_subcategories=true` params are present. This
is because the controller did not account for sub-subcategories when
fetching the category ids of the new topics that should be dismissed.
This commit fixes the problem by relying on the `Category.subcategory_ids` class
method which accounts for sub-subcategories.
What is the problem here?
In multiple controllers, we are accepting a `limit` params but do not
impose any upper bound on the values being accepted. Without an upper
bound, we may be allowing arbituary users from generating DB queries
which may end up exhausing the resources on the server.
What is the fix here?
A new `fetch_limit_from_params` helper method is introduced in
`ApplicationController` that can be used by controller actions to safely
get the limit from the params as a default limit and maximum limit has
to be set. When an invalid limit params is encountered, the server will
respond with the 400 response code.
What is the context for this change?
Prior to this change, there is a bug in `TopicsController#reset_new`
where it does not dismiss new topics in sub-subcategories when the
`category_id` and `include_subcategories=true` params are present. This
is because the controller did not account for sub-subcategories when
fetching the category ids of the new topics that should be dismissed.
This commit fixes the problem by relying on the `Category.subcategory_ids` class
method which accounts for sub-subcategories.
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.
We have a number of raw comments indicating that certain methods and classes are deprecated and marked for removal. This change turn those comments into deprecation warnings so that we can 1) see them in the logs of our own hosting and 2) give some warning to self hosters.
Why this change?
Prior to this change, we would only return tags that are used in at
least one public topic. However, this is confusing for users because the
tag could be used in a restricted category and that is not considered a
"public" topic. Instead, we will just display all the tags in the edit
tags navigation modal as long as it is visible to the user.
Why this change?
Prior to this change, dismissing unreads posts did not publish the
changes across clients for the same user. As a result, users can end up
seeing an unread count being present but saw no topics being loaded when
visiting the `/unread` route.
* FEATURE: Inline topic summary. Cached version accessible to everyone.
Anons and non-members of the `custom_summarization_allowed_groups_map` groups can see cached summaries for any accessible topic. After the first 12 hours and if the posts to summarize have changed, allowed users clicking on the button will automatically re-generate it.
* Ensure chat summaries work and prevent model hallucinations when there are no messages.
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.
Some plugins call require_plugin with a wrong argument instead of the
plugin name. In a production environment that used to be a warning, but
there is no reason to keep it like that in a testing environment
because the issue will continue to be ignored.
Follow-up to b27e12445d
This commit adds 2 new site settings `default_sidebar_link_to_filtered_list` and `default_sidebar_show_count_of_new_items` to control the default values for the navigation menu preferences that were added in the linked commit (`sidebar_link_to_filtered_list` and `sidebar_show_count_of_new_items` respectively).
What is the problem?
Before this change, we were relying on the `/tags` endpoint which
returned all the tags that are visible to a give user on the site leading to potential performance problems.
The attribute keys of the response also changes based on the `tags_listed_by_group` site setting.
What is the fix?
This commit fixes the problems listed above by creating a dedicate `#list` action in the
`TagsController` to handle the listing of the tags in the edit
navigation menu tags modal. This is because the `TagsController#index`
action was created specifically for the `/tags` route and the response
body does not really map well to what we need. The `TagsController#list`
action added here is also much safer since the response is paginated and
we avoid loading a whole bunch of tags upfront.
]When changing fonts in the `/wizard/steps/styling` step of
the wizard, users would not see the font loaded straight away,
having to switch to another one then back to the original to
see the result. This is because we are using canvas to render
the style preview and this fails with a Chrome-based intervention
when font loading is taking too long:
> [Intervention] Slow network is detected. See
https://www.chromestatus.com/feature/5636954674692096 for more details.
Fallback font will be used while loading:
https://sea2.discourse-cdn.com/business7/fonts/Roboto-Bold.ttf?v=0.0.9
We can get around this by manually loading the fonts selected using
the FontFace JS API when the user selects them and before rerendering
the canvas. This just requires preloading more information about the
fonts if the user is admin so the wizard can query this data.
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.
Updates the interface for implementing summarization strategies and adds a cache layer to summarize topics once.
The cache stores the final summary and each chunk used to build it, which will be useful when we have to extend or rebuild it.
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'
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 ;)
* DEV: Implement staff logs for user columns edits
* deleted extra space in staff logger detail string, deleted string when no changes are made, added basic test coverage for EditDirectoryColumnsController
* fixed change made to #self.staff_actions un UserHistory
* implemented a method that builds the details, previous_values and new_values in a dynamic way
* removed details of changes
* refactored small merge
Calling pluck is instantly making a SELECT, while passing the relationship allows rails to build a correct query.

Post Count (2.7ms) SELECT COUNT(*) FROM "posts" WHERE "posts"."deleted_at" IS NULL AND "posts"."topic_id" IN (SELECT "topics"."id" FROM "topics" WHERE "topics"."deleted_at" IS NULL AND "topics"."id" IN (1, 3, 4))
```
Display modal for combined new and unread view with options:

What is the problem?
The user messages routes are currently routed by the server to
`UserActionsController#private_messages`. However, the method is
essentially a no-op and does not do any preloading. As a result, when we
load the user private messages routes, the client ends up having to
issue another request to the server to get more information about the
user profile currently being viewed. This extra request is triggered by
the `user` model's `findDetails` method that is called from the `user`
route in the `afterModel` hook.
What is the solution?
The `user` model's `findDetails` method actually checks the preload
store to see if the `user_${username}` key is present in the store and
if it is, it will use the preloaded data instead of triggering another
request. Since the user private messages routes are nested under the
user route on the client side, we have to rely on the
`UsersController#show` controller action on the server side for the user private
messages route as the `UsersController#show` controller action preloads
the required user information for the client side.
Prior to this commit, we didn't have RTL versions of our admin and plugins CSS bundles and we always served LTR versions of those bundles even when users used an RTL locale, causing admin and plugins UI elements to never look as good as when an LTR locale was used. Example of UI issues prior to this commit were: missing margins, borders on the wrong side and buttons too close to each other etc.
This commit creates an RTL version for the admin CSS bundle as well as RTL bundles for all the installed plugins and serves those RTL bundles to users/sites who use RTL locales.
This commit adds modifiers that allow plugins to change how categories and groups are prefetched into the application and listed in the respective controllers.
Possible use cases:
- prevent some categories/groups from being prefetched when the application loads for performance reasons.
- prevent some categories/groups from being listed in their respective index pages.
Allow admins to edit Community section. This includes drag and drop reorder, change names, delete and reset to default.
Visual improvements introduced in edit community section modal are available in edit custom section form as well. For example:
- drag and drop links to change their position;
- smaller icon picker.
This commit introduces a new `within_user_updater_transaction` event that's triggered inside the transaction that saves user updates in `UserUpdater`. Plugins can hook into the transaction using the event to include custom changes in the transaction. Callbacks for this event receive 2 arguments:
1. the user being saved
2. the changed attributes that are passed to `UserUpdater`.
There's also new modifier in this commit called `users_controller_update_user_params` to allow plugins to allowlist custom params in the `UsersController` which eventually end up getting passed as attributes to the `UserUpdater` and the new `within_user_updater_transaction` event where they can be used to perform additional updates using the custom params.
-----
New API is used in https://github.com/discourse/discourse-mailinglist-integration/pull/1.
When a user chooses to move a topic/message to an existing topic/message, they can now opt to merge the posts chronologically (using a checkbox in the UI).
The field more_topic_url is already included in the response preloaded in categories#index
However this field was missing if a request was subsequently made to update the page using
the end-points /categories_and_latest or /categories_and_top. This could lead the client
app to display incorrect information if it relied on this information to update the UI.
This commit deprecates the `modify_user_params` method in `UsersController` in favor of a new modifier that replaces that method whose entire purpose is to allow plugins to monkey-patch it to permit custom params in the controller. We now have the "modifier" system which can achieve the same results but in a safer and easier way. The modifier that replaces the deprecated method is included in PR https://github.com/discourse/discourse/pull/21737.
What is this change required?
I noticed that actions in `SidebarSectionsController` resulted in
lots of N+1 queries problem and I wanted a solution to
prevent such problems without having to write N+1 queries tests. I have
also used strict loading for `SidebarSection` queries in performance
sensitive spots.
Note that in this commit, I have also set `config.active_record.action_on_strict_loading_violation = :log`
for the production environment so that we have more visibility of
potential N+1 queries problem in the logs. In development and test
environment, we're sticking with the default of raising an error.
When uploading images via direct to S3 upload, we were
assuming that we could not pre-emptively check the file
size because the client may do preprocessing to reduce
the size, and UploadCreator could also further reduce the
size.
This, however, is not true of gifs, so we would have an
issue where you upload a gif > the max_image_size_kb
setting and had to wait until the upload completed for
this error to show.
Now, instead, when we direct upload gifs to S3, we check
the size straight away and present a file size error to
the user rather than making them wait. This will increase
meme efficiency by approximately 1000%.
What is the problem?
In `SvgSpriteController#search` and `SvgSpriteController#icon_picker_search`, the controller actions
was using the `RailsMultisite::ConnectionManagement.with_hostname` API
but `params[:hostname]` was always `nil` because the routes does not
have a `:hostname` param component and the client does not ever pass the
`:hostname` param when making the request. When `RailsMultisite::ConnectionManagement.with_hostname` is
used with a `nil` argument, it ends up connecting to the default
multisite database. Usually this would be bad because we're allowing a
site in a multisite setup to connect to another site but thankfully no
private data is being leaked here.
What is the fix?
Since `SvgSpriteController#search` and `SvgSpriteController#icon_picker_search` are login required route,
there is no need for us to switch database connections. The fix here is
to simply remove the use of `RailsMultisite::ConnectionManagement.with_hostname`.
### What is the problem?
It is possible to pass an arbitrary value to the limit parameter in `TagsController#search`, and have it flow through `DiscourseTagging.filter_allowed_tags` where it will raise an error deep in the database driver. MiniSql ensures there's no injection happening, but that ultimately results in an invalid query.
### How does this fix it?
This change checks more strictly that the parameter can be cleanly converted to an integer by replacing the loose `#to_i` conversion semantics with the stronger `Kernel#Integer` ones.
**Example:**
```ruby
"1; SELECT 1".to_i
#=> 1
Integer("1; SELECT 1")
#=> ArgumentError
```
As part of the change, I also went ahead to disallow a limit of "0", as that doesn't seem to be a useful option. Previously only negative limits were disallowed.
