What does this change do?
This commit the client to override the navigation menu setting
configured by the site temporarily based on the value of the
`navigation_menu` query param. The new query param replaces the old
`enable_sidebar` query param.
Why do we need this change?
The motivation here is to allow theme maintainers to quickly preview
what the site will look like with the various navigation menu site
setting.
Previously, a user avatar redirect had a lifetime of 24h. That means that a change to the S3 CDN URL would take up to 24h to propagate to clients and intermediate CDNs.
This commit reduces the max age to 1 hour, but also introduces a `stale-while-revalidate` directive. This allows clients and CDNs to use a 'stale' value if it was received between 1h and 24h ago, as long as they make a background request to update the cache. This should reduce the impact of S3 URL changes. 1 hour after the change, the CDN will start serving updated values. Plus, if users have cached bad responses, their browser will automatically fetch the correct version and use it on the next page load.
The #pluck_first freedom patch, first introduced by @danielwaterworth has served us well, and is used widely throughout both core and plugins. It seems to have been a common enough use case that Rails 6 introduced it's own method #pick with the exact same implementation. This allows us to retire the freedom patch and switch over to the built-in ActiveRecord method.
There is no replacement for #pluck_first!, but a quick search shows we are using this in a very limited capacity, and in some cases incorrectly (by assuming a nil return rather than an exception), which can quite easily be replaced with #pick plus some extra handling.
When a post is created using the API and goes into the review queue, we
would return a 'null' string in the response which isn't valid JSON.

Improvements for this PR: https://github.com/discourse/discourse/pull/20057
What was fixed:
- [x] Use ember transitions instead of full reload
- [x] Link was inaccurately kept active
- [x] "+ save" renamed to just "save"
- [x] Render emojis in link name
- [x] UI to set icon
- [x] Delete link is trash icon instead of "x"
- [x] Add another link to on the left and rewording
- [x] Raname "link name" -> "name", "points to" -> link
- [x] Add limits to fields
- [x] Move add section button to the bottom
Allows users to configure their own custom sidebar sections with links withing Discourse instance. Links can be passed as relative path, for example "/tags" or full URL.
Only path is saved in DB, so when Discourse domain is changed, links will be still valid.
Feature is hidden behind SiteSetting.enable_custom_sidebar_sections. This hidden setting determines the group which members have access to this new feature.
1. What is the problem here?
When a user's reviewables count changes, the changes are published via
MessageBus in a background Sidekiq job which means there is a delay before the
client receives the MessageBus message with the updated count. During
the time the reviewables count for a user has been updated and the time
when the client receives the MessageBus message with the updated count,
a user may view the reviewables list in the user menu. When that happens, the number of
reviewables in the list may be out of sync with the count shown.
2. What is the fix?
Going forward, the response for the `ReviewablesController#user_menu_list` action will include the user's reviewables count as
the `reviewables_count` attribute. This is then used by the client side
to update the user's reviewables count to ensure that the reviewables
list and count are kept in sync.
## Why do we need this change?
When loading the ember app, [MessageBus does not start polling immediately](f31f0b70f8/app/assets/javascripts/discourse/app/initializers/message-bus.js (L71-L81)) and instead waits for `document.readyState` to be `complete`. What this means is that if there are new messages being created while we have yet to start polling, those messages will not be received by the client.
With sidebar being the default navigation menu, the counts derived from `topic-tracking-state.js` on the client side is prominently displayed on every page. Therefore, we want to ensure that we are not dropping any messages on the channels that `topic-tracking-state.js` subscribes to.
## What does this change do?
This includes the `MessageBus.last_id`s for the MessageBus channels which `topic-tracking-state.js` subscribes to as part of the preloaded data when loading a page. The last ids are then used when we subscribe the MessageBus channels so that messages which are published before MessageBus starts polling will not be missed.
## Review Notes
1. See https://github.com/discourse/message_bus#client-support for documentation about subscribing from a given message id.
Currently `Topic#pm_topic_count` is a count of all personal messages tagged for a given tag. As a result, any user with access to PM tags can poll a sensitive tag to determine if a new personal message has been created using that tag even if the user does not have access to the personal message. We classify this as a minor leak in sensitive information.
With this commit, `Topic#pm_topic_count` is hidden from users by default unless the `display_personal_messages_tag_counts` site setting is enabled.
A while back the definition of TL was changed but many
areas in the codebase still use the term 'Regular user'
despite it having some implicit meaning (TL2).
See 20140905055251_rename_trust_level_badges.rb
When the `tags_listed_by_group` site setting is disable, we were seeing
the N+1 queries problem when multiple `CategoryTag` records are listed.
This commit fixes that by ensuring that we are not filtering through the
category `tags` association after the association has been eager loaded.
* FIX: Ensure soft-deleted topics can be deleted
The topic was not found during the deletion process because it was
deleted and `@post.topic` was nil.
* DEV: Use @topic instead of finding the topic every time
This commit allows us to set the channel slug when creating new chat
channels. As well as this, it introduces a new `SlugsController` which can
generate a slug using `Slug.for` and a name string for input. We call this
after the user finishes typing the channel name (debounced) and fill in
the autogenerated slug in the background, and update the slug input
placeholder.
This autogenerated slug is used by default, but if the user writes anything
else in the input it will be used instead.
Currently, `Tag#topic_count` is a count of all regular topics regardless of whether the topic is in a read restricted category or not. As a result, any users can technically poll a sensitive tag to determine if a new topic is created in a category which the user has not excess to. We classify this as a minor leak in sensitive information.
The following changes are introduced in this commit:
1. Introduce `Tag#public_topic_count` which only count topics which have been tagged with a given tag in public categories.
2. Rename `Tag#topic_count` to `Tag#staff_topic_count` which counts the same way as `Tag#topic_count`. In other words, it counts all topics tagged with a given tag regardless of the category the topic is in. The rename is also done so that we indicate that this column contains sensitive information.
3. Change all previous spots which relied on `Topic#topic_count` to rely on `Tag.topic_column_count(guardian)` which will return the right "topic count" column to use based on the current scope.
4. Introduce `SiteSetting.include_secure_categories_in_tag_counts` site setting to allow site administrators to always display the tag topics count using `Tag#staff_topic_count` instead.
Our JS files reference sourcemaps relative to their current path. On sites with non-S3 CDN setups, we use a special path for brotli assets (39a524aa). This caused the sourcemap requests to 404.
This commit fixes the issue by allowing the `.map` files to be accessed under `/brotli_asset/*`.
When the `tags_listed_by_group` site setting is enabled, we were seeing
the N+1 queries problem when multiple `TagGroup` records are listed.
This commit fixes that by ensuring that we are not filtering through the
`tags` association after the association has been eager loaded.
This is a very subtle one. Setting the redirect URL is done by passing
a hash through a Discourse event. This is broken on Ruby 2 since the
support for keyword arguments in events was added.
In Ruby 2 the last argument is cast to keyword arguments if it is a
hash. The key point here is that creates a new copy of the hash, so
what the plugin is modifying is not the hash that was passed.
In "GlobalSetting.redirect_avatar_requests" mode, when the application gets
an avatar request it returns a "redirect" to the S3 CDN.
This shields the application from caching avatars and downloading from S3.
However clients will make 2 requests per avatar. (one to get redirect,
second to get avatar)
A one hour cache on a redirect means there may be an increase in CDN
traffic, given more clients will ask for the redirect every hour.
This may also lead to an increase in origin requests to the application.
To mitigate lets cache the CDN URL for 1 day.
The downside is that any changes to S3 CDN need extra care to allow for
the extra 1 day delay. (leave data around for 1 extra day)
Previously, calling `sign_in` would cause the browser to be redirected to `/`, and would cause the Ember app to boot. We would then call `visit()`, causing the app to boot for a second time.
This commit adds a `redirect=false` option to the `/session/username/become` route. This avoids the unnecessary boot of the app, and leads to significantly faster system spec run times.
In local testing, this takes the full system-spec suite for chat from ~6min to ~4min.
We were changing the user's user_option.bookmark_auto_delete_preference
to whatever they changed it to in the bookmark modal to use as default
for future bookmarks. However this was leading to a lot of confusion
since if you wanted to set it for one bookmark you had to remember to
change it back on the next one.
This commit removes that automatic functionality, and instead moves
the bookmark auto delete preference to User Preferences > Interface
in an explicit dropdown.
This commit adds a new notification that gets sent to admins when the site gets new features after an upgrade/deploy. Clicking on the notification takes the admin to the admin dashboard at `/admin` where they can see the new features under the "New Features" section.

* 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.
This commit allows us to type # in the UI and present autocomplete
results immediately with the following logic for the topic composer,
and reversed for the chat composer:
* Categories the user can access and has not muted sorted by `topic_count`
* Tags the user can access and has not muted sorted by `topic_count`
* Chat channels the user is a member of sorted by `messages_count`
So in effect, we allow searching for hashtags without a search term.
To do this we add a new `search_without_term` to each data source so
each one can define how it wants to handle this logic.
This new site setting replaces the
`enable_experimental_sidebar_hamburger` and `enable_sidebar` site
settings as the sidebar feature exits the experimental phase.
Note that we're replacing this without depreciation since the previous
site setting was considered experimental.

When uploads are stored on S3, by default Discourse will fetch the avatars and proxy them through to the requesting client. This is simple, but it can lead to significant inbound/outbound network load in the hosting environment.
This commit adds an optional redirect_avatar_requests GlobalSetting. When enabled, requests for user avatars will be redirected to the S3 asset instead of being proxied. This adds an extra round-trip for clients, but it should significantly reduce server load. To mitigate that extra round-trip for clients, a CDN with 'follow redirect' capability could be used.
Users who can access the review queue can claim a pending reviewable(s) which means that the claimed reviewable(s) can only be handled by the user who claimed it. Currently, we show claimed reviewables in the user menu, but this can be annoying for other reviewers because they can't do anything about a reviewable claimed by someone. So this PR makes sure that we only show in the user menu reviewables that are claimed by nobody or claimed by the current user.
Internal topic: t/77235.
While load testing our user creation code path in production, we
identified that executing the DB statement to update the `Group#user_count` column within a
transaction is creating a bottleneck for us. This is because the
creation of a user and addition of the user to the relevant groups are
done in a transaction. When we execute the DB statement to update
`Group#user_count` for the relevant group, a row level lock is held
until the transaction completes. This row level lock acts like a global
lock when the server is creating users that will be added to the same
group in quick succession.
Instead of updating the counter cache within a transaction which the
default ActiveRecord `counter_cache` option does, we simply update the
counter cache outside of the committing transaction.

I'm hesitant to call this a performance improvement since claiming a
reviewable is probably rare. However, this commit cuts out two DB
queries each time we have to publish a reviewable claimed message. More
importantly, publishing to groups scales much better than publishing to
users because we esstentially cap the number ids we have to load into
memory.
This adds API scope for the user status. This also adds a get method to the user status controller. We didn't need a dedicated method that returns status before because the server returns status with user objects, but I think we need to provide this method for API clients.
This commit fleshes out and adds functionality for the new `#hashtag` search and
lookup system, still hidden behind the `enable_experimental_hashtag_autocomplete`
feature flag.
**Serverside**
We have two plugin API registration methods that are used to define data sources
(`register_hashtag_data_source`) and hashtag result type priorities depending on
the context (`register_hashtag_type_in_context`). Reading the comments in plugin.rb
should make it clear what these are doing. Reading the `HashtagAutocompleteService`
in full will likely help a lot as well.
Each data source is responsible for providing its own **lookup** and **search**
method that returns hashtag results based on the arguments provided. For example,
the category hashtag data source has to take into account parent categories and
how they relate, and each data source has to define their own icon to use for the
hashtag, and so on.
The `Site` serializer has two new attributes that source data from `HashtagAutocompleteService`.
There is `hashtag_icons` that is just a simple array of all the different icons that
can be used for allowlisting in our markdown pipeline, and there is `hashtag_context_configurations`
that is used to store the type priority orders for each registered context.
When sending emails, we cannot render the SVG icons for hashtags, so
we need to change the HTML hashtags to the normal `#hashtag` text.
**Markdown**
The `hashtag-autocomplete.js` file is where I have added the new `hashtag-autocomplete`
markdown rule, and like all of our rules this is used to cook the raw text on both the clientside
and on the serverside using MiniRacer. Only on the server side do we actually reach out to
the database with the `hashtagLookup` function, on the clientside we just render a plainer
version of the hashtag HTML. Only in the composer preview do we do further lookups based
on this.
This rule is the first one (that I can find) that uses the `currentUser` based on a passed
in `user_id` for guardian checks in markdown rendering code. This is the `last_editor_id`
for both the post and chat message. In some cases we need to cook without a user present,
so the `Discourse.system_user` is used in this case.
**Chat Channels**
This also contains the changes required for chat so that chat channels can be used
as a data source for hashtag searches and lookups. This data source will only be
used when `enable_experimental_hashtag_autocomplete` is `true`, so we don't have
to worry about channel results suddenly turning up.
------
**Known Rough Edges**
- Onebox excerpts will not render the icon svg/use tags, I plan to address that in a follow up PR
- Selecting a hashtag + pressing the Quote button will result in weird behaviour, I plan to address that in a follow up PR
- Mixed hashtag contexts for hashtags without a type suffix will not work correctly, e.g. #ux which is both a category and a channel slug will resolve to a category when used inside a post or within a [chat] transcript in that post. Users can get around this manually by adding the correct suffix, for example ::channel. We may get to this at some point in future
- Icons will not show for the hashtags in emails since SVG support is so terrible in email (this is not likely to be resolved, but still noting for posterity)
- Additional refinements and review fixes wil
* FEATURE: API to update user's discourse connect external id
This adds a special handling of updates to DiscourseConnect external_id
in the general user update API endpoint.
Admins can create, update or delete a user SingleSignOn record using
PUT /u/:username.json
{
"external_ids": {
"discourse_connect": "new-external-id"
}
}
When opening the invite acceptance page when the user
was already logged in, we were still showing the Accept
Invitation prompt even if the user had already redeemed
the invitation and was present in the `InvitedUser` table.
This would lead to errors when the user clicked on the button.
This commit fixes the issue by hiding the Accept Invitation
button and showing an error message instead indicating that
the user had already redeemed the invitation. This only applies
to multi-use invite links.
The problem was reported as a problem with changing theme in user preferences, after saving a new theme the previously set user status was disappearing (https://meta.discourse.org/t/user-status/240335/42). Turned out though that the problem was more wide, changing pretty much any setting in user preferences apart from user status itself led to clearing the status.
This commit adds some protections in InviteRedeemer to ensure that email
can never be nil, which could cause issues with inviting the invited
person to private topics since there was an incorrect inner join.
If the email is nil and the invite is scoped to an email, we just use
that invite.email unconditionally. If a redeeming_user (an existing
user) is passed in when redeeming an email, we use their email to
override the passed in email. Otherwise we just use the passed in
email. We now raise an error after all this if the email is still nil.
This commit also adds some tests to catch the private topic fix, and
some general improvements and comments around the invite code.
This commit also includes a migration to delete TopicAllowedUser records
for users who were mistakenly added to topics as part of the invite
redemption process.
Currently, moderators are able to set primary group for users
irrespective of the of the `moderators_manage_categories_and_groups` site
setting value.
This change updates Guardian implementation to honour it.
This commit fixes the issue where the sub-category topic list was not
loading for new-topic routes. Since we do not need to preload topic
lists for new topic/message routes this commit adds a no-op controller
that prevents topic lists pre loading and at the same time fixes the sub
category topics not loading issue.
Previously, we didn't have a site-wide setting to set the default behavior for user profile visibility and user presence features. But we already have a user preference for that.
* DEV: Add a dedicated Admin::StaffController base controller
The current parent(Admin:AdminController) for all admin-related controllers
uses a filter that allows only staff(admin, moderator) users.
This refactor makes Admin::AdminController filter for only admins as the name suggests and
introduces a base controller dedicated for staff-related endpoints.
* DEV: Set staff-only controllers parent to Admin::StaffController
Refactor staff-only controllers to inherit newly introduced
Admin::StaffController abstract controller. This conveys the
purpose of the parent controller better unlike the previously used parent
controller.

Before this commit, we did not have guardian checks in place to determine if a
topic's title associated with a user badge should be displayed or not.
This means that the topic title of topics with restricted access
could be leaked to anon and users without access if certain conditions
are met. While we will not specify the conditions required, we have internally
assessed that the odds of meeting such conditions are low.
With this commit, we will now apply a guardian check to ensure that the
current user is able to see a topic before the topic's title is included
in the serialized object of a `UserBadge`.
The previous sidebar default tags and categories implementation did not
allow for a user to configure their sidebar to have no categories or
tags. This commit changes how the defaults are applied. When a user is being created,
we create the SidebarSectionLink records based on the `default_sidebar_categories` and
`default_sidebar_tags` site settings. SidebarSectionLink records are
only created for categories and tags which the user has visibility on at
the point of user creation.
With this change, we're also adding the ability for admins to apply
changes to the `default_sidebar_categories` and `default_sidebar_tags`
site settings historically when changing their site setting. When a new
category/tag has been added to the default, the new category/tag will be
added to the sidebar for all users if the admin elects to apply the changes historically.
Like wise when a tag/category is removed, the tag/category will be
removed from the sidebar for all users if the admin elects to apply the
changes historically.

This commit adds a new `/hashtag/search` endpoint and both
relevant JS and ruby plugin APIs to handle plugins adding their
own data sources and priority orders for types of things to search
when `#` is pressed.
A `context` param is added to `setupHashtagAutocomplete` which
a corresponding chat PR https://github.com/discourse/discourse-chat/pull/1302
will now use.
The UI calls `registerHashtagSearchParam` for each context that will
require a `#` search (e.g. the topic composer), for each type of record that
the context needs to search for, as well as a priority order for that type. Core
uses this call to add the `category` and `tag` data sources to the topic composer.
The `register_hashtag_data_source` ruby plugin API call is for plugins to
add a new data source for the hashtag searching endpoint, e.g. discourse-chat
may add a `channel` data source.
This functionality is hidden behind the `enable_experimental_hashtag_autocomplete`
flag, except for the change to `setupHashtagAutocomplete` since only core and
discourse-chat are using that function. Note this PR does **not** include required
changes for hashtag lookup or new styling.
This commit excludes posts from hidden topics from the latest posts and user activity RSS feeds. Additionally, it also excludes small actions from the first one.
Theme javascript is now minified using Terser, just like our core/plugin JS bundles. This reduces the amount of data sent over the network.
This commit also introduces sourcemaps for theme JS. Browser developer tools will now be able show each source file separately when browsing, and also in backtraces.
For theme test JS, the sourcemap is inlined for simplicity. Network load is not a concern for tests.
This commit introduces a new framework for building user tutorials as
popups using the Tippy JS library. Currently, the new framework is used
to replace the old notification spotlight and tips and show a new one
related to the topic timeline.
All popups follow the same structure and have a title, a description and
two buttons for either dismissing just the current tip or all of them
at once.
The state of all seen popups is stored in a user option. Updating
skip_new_user_tips will automatically update the list of seen popups
accordingly.

Experiment moving from preload tags in the document head to preload information the the response headers.
While this is a minor improvement in most browsers (headers are parsed before the response body), this allows smart proxies like Cloudflare to "learn" from those headers and build HTTP 103 Early Hints for subsequent requests to the same URI, which will allow the user agent to download and parse our JS/CSS while we are waiting for the server to generate and stream the HTML response.

2. Unread and read `group_message_summary` notifications (notifications when there's a new message in a group inbox that you track)
3. Non-archived personal and group messages
Unread `private_message` notifications are always shown first, followed by unread `group_message_summary` notifications, and then everything else (messages and read `group_message_summary` notifications) sorted by recency (most recent first).

This commit renames all secure_media related settings to secure_uploads_* along with the associated functionality.
This is being done because "media" does not really cover it, we aren't just doing this for images and videos etc. but for all uploads in the site.
Additionally, in future we want to secure more types of uploads, and enable a kind of "mixed mode" where some uploads are secure and some are not, so keeping media in the name is just confusing.
This also keeps compatibility with the `secure-media-uploads` path, and changes new
secure URLs to be `secure-uploads`.
Deprecated settings:
* secure_media -> secure_uploads
* secure_media_allow_embed_images_in_emails -> secure_uploads_allow_embed_images_in_emails
* secure_media_max_email_embed_image_size_kb -> secure_uploads_max_email_embed_image_size_kb
* FEATURE: add composer warning when user haven't been seen in a long time
When a user creates a PM and adds a recipient that hasn't been seen in a
long time then we'll now show a warning in composer indicating that the
user hasn't been seen in a long time.
This will replace `enable_personal_messages` and
`min_trust_to_send_messages`, this commit introduces
the setting `personal_message_enabled_groups`
and uses it in all places that `enable_personal_messages`
and `min_trust_to_send_messages` currently apply.
A migration is included to set `personal_message_enabled_groups`
based on the following rules:
* If `enable_personal_messages` was false, then set
`personal_message_enabled_groups` to `3`, which is
the staff auto group
* If `min_trust_to_send_messages` is not default (1)
and the above condition is false, then set the
`personal_message_enabled_groups` setting to
the appropriate auto group based on the trust level
* Otherwise just set `personal_message_enabled_groups` to
11 which is the TL1 auto group
After follow-up PRs to plugins using these old settings, we will be
able to drop the old settings from core, in the meantime I've added
DEPRECATED notices to their descriptions and added them
to the deprecated site settings list.
This commit also introduces a `_map` shortcut method definition
for all `group_list` site settings, e.g. `SiteSetting.personal_message_enabled_groups`
also has `SiteSetting.personal_message_enabled_groups_map` available,
which automatically splits the setting by `|` and converts it into
an array of integers.
