This patch allows using an AR relation as a model in services without
fetching associated records. It will just check if the relation is empty
or not. In the former case, the execution will stop at that point, as
expected.
This is a follow-up to 671f40ce07 and
ed11ee9d05.
While the optimisations in the previous commits were sound, it did not
resolve the memory bloat we were seeing. It turns out that we call
`.blank?` on the model's result if the model has not been marked
optional. The problem with this is that if the model returns an
ActiveRecord relation, calling `.blank?` on the relation basically loads
everything into memory.
Therefore, this commit removes `users` as a model in the since it really isn't
a model but just a relation.
This is a follow up to ed11ee9d05.
In `Chat::AutoRemove::HandleCategoryUpdated`, we are currently loading
the related users record in batches and then handing it off to
`Chat::Action::CalculateMembershipsForRemoval.call`. However, we are
still seeing memory spike as a result of this.
This commit eliminates the allocation of `User` ActiveRecord objects until
absolutely necessary. `Chat::Action::CalculateMembershipsForRemoval.call` has been
updated to accept an ActiveRecord relation instead which allows us to
avoid the ActiveRecord allocations.
This commit seeks to reduce the memory footprint of `Chat::AutoRemove::HandleCategoryUpdated.call`
by optimizing the
`Chat::AutoRemove::HandleCategoryUpdated#remove_users_without_channel_permission` method which was
loading all the ActiveRecord users objects into memory at once. This
change updates the method call to load the ActiveRecord user objects in
batches instead.
* FIX: Remove chat default channel being applied to mobile chat and drawer
* DEV: removing chat_default_channel_id setting
* DEV: add migration to remove chat default channel id
* DEV: remove default_channel_validator and tests
This change allows us to distinguish between regular user generated chat messages and those created via the Chat SDK.
A new created_by_sdk boolean column is added to the Chat Messages table. When this value is true, we will not include the message in the user summary email that is sent to users.
I am changing many of these to notes or resolving them as is,
most of these I have not actively worked on in years so someone
else can work on them when we get to these areas again.
We want to allow admins to make new required fields apply to existing users. In order for this to work we need to have a way to make those users fill up the fields on their next page load. This is very similar to how adding a 2FA requirement post-fact works. Users will be redirected to a page where they can fill up the remaining required fields, and until they do that they won't be able to do anything else.

When chat is enabled, there's a scheduled job that runs every 5 minutes to check whether we need to send a "chat summary" email to users with unread chat messages or mentions.
On Discourse with a large number of users, the query used wasn't optimal and sometimes taking minutes. Which isn't good when the query is called every 5 minutes 😬
This PR reworks the query in `Chat::Mailer.send_unread_mentions_summary`.
Instead of starting from the `users` table, it starts from the `user_chat_channel_memberships` table which is the main piece tying everything together.
The new query is mostly similar to the previous one, with some bug fixes (like ensuring the user has `allow_private_messages` enabled for direct messages) and is also slightly simpler since it doesn't keep track of the `memberships_with_unread_messages` anymore. That part has been moved to the `user_notifications.chat_summary` email method.
The `UserEmailExtension` has been deleted since that was using to N+1 update the `user_chat_channel_memberships.last_unread_mention_when_emailed_it`(quite a mouthful 😛) but that's now done directly in the `user_notifications.chat_summary` email method.
The "plat de résistance" of that PR - the `user_notifications.chat_summary` method has been re-worked for improved performances 🚀
Instead of doing everything in one query, it does 4 tiny ones.
- One to retrieve the list of unread mentions (@something) in "category" channels
- One to retrieve the list of unread messages in "direct message" channels (aka. 1-1 and group discussions)
- One to load all the chat messages for each "category" channels from the last unread mention
- One to load all the chat messages for each "direct message" channels from the last unread message
All the specs for both `Chat::Mailer` and `UserNotification.chat_summary` have been rewriten for easier comprehension and faster execution (mostly by not using chat services which makes the specs go 10x slower...)
Internal ref - t/129848
This change allows the correct number of members to be added when creating a group direct message, based on the site setting chat_max_direct_message_users.
Previously we counted the current user within the max user limit and therefore the count was off by 1.
Before this fix we could only list messages of a thread if it was part of a `threading_enabled` channel or if the thread was set to `force`.
Due to our design of also using a thread id when this is just a chain of replies so we can switch from threading enabled to disabled at any time, we will allow `Chat:: ListChannelThreadMessages` to list the messages of any thread, the only important requirements are:
- having a thread id
- being able to access this thread
To allow this, this commit simply removes the check on `threading_enabled` or `force`.
Prior to this fix we had too logic to detect if a user is active or not:
- idle codepath on the frontend
- online user ids on the backend
The frontend solution is not very reliable, and both solution are just trying to be too smart. Making a lot of people questioning why they receive a notification sometimes and sometimes not. This commit removes all this logic and replaces it with a much more simpler logic:
- you can't receive notifications for channel you are actually watching
- we won't play a sound more than once every 3seconds
When users click a link that points to an existing group chat, we should reopen that chat instead of creating a new group chat so users can more easily continue ongoing conversations.
When a user had the chat option "Show activity indicator in header" set to "all new messages", and they would get a reply to a thread they're part of, the chat icon in the header would not show the unread bubble indicator.
In order to fix this, the `ChatHeaderIconUnreadIndicator` component will now `showUnreadIndicator` whenever there is either one unread public channel or there are unread threads.
I only added a system spec for this very specific path because I don't want to slow down the whole suite to test for all the various combination of the `chat_header_indicator_preference` values.
Internal ref - t/128874
When you reply to a chat message, we [always create a thread][1]. But when the channel we're in doesn't have threading enabled, the reply is _technically_ not a thread.
This changes the `in_thread?` method to check for both the presence of a `thread_id` and to ensure that the channel has `threading_enabled`.

Prior to this commit, only system users had this pass.
Another significant change of the PR, is to make membership of a channel the angular stone of the permission check to create/update/stop streaming a message. The idea being, if you are a member of a channel already we don't need to check if you can join it AGAIN.
We also have `Chat::AutoRemove::HandleCategoryUpdated` which will deal with permissions change so it's simpler and less prone to error to consider the membership as the only source of truth.
There's no point checking if a user can join a channel if they are already part of it. This case was frequent when using `enforce_membership: true` for custom bots for example.
This commit introduces several enhancements to the ChatSDK module, aiming to improve the functionality and usability of chat thread interactions. Here's what has been changed and added:
1. **New Method: `first_messages`:**
- Added a method to retrieve the first set of messages from a specified chat thread.
- This method is particularly useful for fetching initial messages when entering a chat thread.
- Parameters include `thread_id`, `guardian`, and an optional `page_size` which defaults to 10.
- Usage example added to demonstrate fetching the first 15 messages from a thread.
2. **New Method: `last_messages`:**
- Added a method to retrieve the last set of messages from a specified chat thread.
- This method supports reverse pagination, where the user may want to see the most recent messages first.
- Similar to `first_messages`, it accepts `thread_id`, `guardian`, and an optional `page_size` parameter, defaulting to 10.
- Usage example provided to illustrate fetching the last 20 messages from a thread.
The TextCleaner step has been moved from chat message’s validation to create_message/update_message services. It allows us to easily tweak part of its behavior depending on the needs.
For example we will now disable strip_whitespaces by default when streaming messages as we want to keep newlines and spaces at the end of the message.
This change encourages users to title their threads to make it easier for other users to join in on conversations that matter to them.
The creator of the chat thread will receive a toast notification prompting them to add a thread title when on mobile and the thread has at least 5 sent replies.
That could cause flakeyness in specs depending in which timing message bus would arrive and it's not necessary as it should be updated with `handleThreadOriginalMessageUpdate`.
Follow up to #26712 to account for older threads that don't have a persisted excerpt, as this was previously generated on every page load.
This change allows us to build the excerpt on the fly when none exists, fixing the issue of missing message excerpts for thread previews (within channel) and thread lists (on mobile/desktop).
This change moves the chat message excerpt into a new database column (string) on the chat_messages table.
As part of this change, we will now set the excerpt within the `Chat::CreateMessage` service, and update it within the `Chat::UpdateMessage` service.
This commit will now allow us to track read position in a thread and returns to this position when you open the thread.
Note this commit is also extracting the following components to make it possible:
- `<ChatMessagesScroller />`
- `<ChatMessagesContainer />`
The `UpdateUserThreadLastRead` has been updated to allow this.
Various refactorings have also been done to the code and specs to improve the support of last read.
Why this change?
When the site setting for chat_max_direct_message_users is set to 1, it is expected that users can have a 1:1 chat with other users. However, since the current user is counting as 1 user it makes starting a new chat impossible.
This change hands this validation off to DirectMessageChannel::MaxUsersExcessPolicy which handles the count correctly by filtering out the current user.
This enables the following in Discourse AI
```
plugin.register_modifier(:chat_allowed_bot_user_ids) do |user_ids, guardian|
if guardian.user
mentionables = AiPersona.mentionables(user: guardian.user)
allowed_bot_ids = mentionables.map { |mentionable| mentionable[:user_id] }
user_ids.concat(allowed_bot_ids)
end
user_ids
end
```
some bots that are id < 0 need to be discoverable in search otherwise people can not talk to them.

We were incorrectly using `return` in a block which was causing exceptions at runtime. These exceptions were not causing much issues as they are in defer block.
While working on writing a test for this specific case, I noticed that our `upsert_custom_fields` function was using rails `update_all` which is not updating the `updated_at` timestamp. This commit also fixes it and adds a test for it.
Prior to this change we would pre-load all the user channels which making initial page load slower. This change will make them be loaded right after initial load. In the past this was not possible as the channels would have to be loaded on each page transition. However since about a year, we made the channels to be cached on the frontend and no other request will be needed.
I have decided for now to not show a loading state in the sidebar as I think it would be noise, but we can reconsider this later.
Note given we don't have the channels loaded at first certain things where harder to accomplish. The biggest UX change of this commit is that we removed all the complex logic of computing the best channel to display when you load /chat. We will now store the id of the last channel you visited and will use this id to decide which channel to show.
Previously services would let you define a high level default `def default_actions_for_service; end` which would define various handlers like `on_success`, after months of usage we consider the cons are superior to the pros here.
Two mains cons:
- people would often not understand where the handling was coming from
- it's easy to miss a case when you write your specs
Forcing a thread will work even in channel which don't have `threading_enabled` or in direct message channels.
For now this feature is only available through the `ChatSDK`:
```ruby
ChatSDK::Message.create(in_reply_to_id: 1, guardian: guardian, raw: "foo bar baz", channel_id: 2, force_thread: true)
```
Prior to this fix if a user had started to reply to a message without actually sending a message, the thread would still be created and we would end up listing it in the threads list of a channel.
This commit also improves adds thread and thread_replies_count to the 4th parameter of the chat_message_created event.
Prior to this fix we were checking if user was not part of a group which allows to chat, but we were not checking if this user was part of groups who can use direct messages.
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.
```ruby
ChatSDK::Message.start_stream(message_id: 1, guardian: guardian)
ChatSDK::Message.stream(raw: "foo", message_id: 1, guardian: guardian)
ChatSDK::Message.stream(raw: "bar", message_id: 1, guardian: guardian)
ChatSDK::Message.stop_stream(message_id: 1, guardian: guardian)
```
Generally speaking only admins or owners of the message can interact with a message. Also note, Streaming to an existing message with a different user won't change the initial user of the message.
Prior to this fix, if the last message of a thread had been made by a deleted user it would cause an exception as we would have no user to display, this commit uses a solution we have been using at other places: the null pattern, through the use of `Chat::NullUser.new`.
Plugins can now register this modifier:
```ruby
register_modifier(:chat_can_create_direct_message_channel) do |user, target_users|
# your logic which should return true or false
end
```
If a user had `123456789` as username, it could be passed to the query as a number and the query would fail as it expects a string.
Also applies the same fix to groups.
This commit introduces the possibility to stream messages. To allow plugins to use streaming this commit also ships a `ChatSDK` library to allow to interact with few parts of discourse chat.
```ruby
ChatSDK::Message.create_with_stream(raw: "test") do |helper|
5.times do |i|
is_streaming = helper.stream(raw: "more #{i}")
next if !is_streaming
sleep 2
end
end
```
This commit also introduces all the frontend parts:
- messages can now be marked as streaming
- when streaming their content will be updated when a new content is appended
- a special UI will be showing (a blinking indicator)
- a cancel button allows the user to stop the streaming, when cancelled `helper.stream(...)` will return `false`, and the plugin can decide exit early
The service `Chat::CreateMessage` will now accept `context_post_ids` and `context_topic_id` as params. These values represent the topic which might be visible when sending a message (for now, this is only possible when using the drawer).
The `DiscourseEvent` `chat_message_created` will now have the following signature:
```ruby
on(:chat_message_created) do | message, channel, user, meta|
p meta[:context][:post_ids]
end
```
Fixes an issue with delayed rendering of the My Threads tab in chat mobile footer.
Previously we made an ajax request to determine the number of threads a user had before rendering the tab, however it is much faster (and better UX) if we can rely on a site setting for this.
The new chat_threads_enabled site setting is set to true when the site has chat channels with threading enabled.
This commit creates a shared implementation of the dates computation and moves all the logic (new messages since last visit and dates separator into one single component <ChatMessageSeparator />).
The frontend tests have been removed and only a single system spec has been added for threads as everything is sharing the same implementation and the existing channel specs should catch any regression.
Allows users to create DMs by selecting groups as a target. It also allows adding user groups to an existing chat
- When creating the channel, it expands the user group and adds all its members with chat enabled to the channel.
- After creation, there's no difference between adding a group or adding its members individually.
- Users can add multiple groups and users simultaneously.
- There are UI validations; the member count preview updates according to the member count of added groups, and it does not allow users to add more members than SiteSetting.chat_max_direct_message_users."
At the moment, when someone is mentioning a group, or using here or
all mention, we create a chat_mention record per user. What we want
instead is to have special kinds of mentions, so we can create only one
chat_mention record in such cases. This PR implements that.
Note, that such mentions will still have N related notifications, one
notification per a user. We don't expect we'll have performance
problems on the notifications side, but if at some point we do, we
should be able to solve them on the side of notifications
(notifications are handled in jobs, also some little delays with
the notifications are acceptable, so we can make sure notifications
are properly queued, and that processing of every notification is
fast enough to make delays small enough).
The preparation work for this PR was done in fbd24fa, where we make
it possible for one mention to have several related notifications.
A pretty tricky part of this PR is schema and data migration, I've explained
related details inline on the migration files.
This update adds three tabs to the bottom of the chat overlay to make it easier for users to navigate chat on mobile.
As a result of this change:
- Direct Messages are now shown separately from public channels on mobile
- My Threads has now moved from the channel list to it's own tab on mobile
- My Threads can still be accessed on desktop via the sidebar and within the drawer channel list
- Chat back button has been updated to navigate to the correct tab (for both channels and threads)
Some special cases:
- If DMs are not used then the tab is not rendered
- If the user has no threads then the tab is not rendered
- If both the tabs for DMs and Threads aren't available then the whole footer will not be rendered
- Chat footer is only shown on the listing pages (DMs, Channels, My Threads)

This regressed in 2791e75072. That commit
fixed subfolder URLs in general, but the `full_url` was adding the
subfolder prefix a second time, thus breaking this URL in emails.
Prior to this fix the number of users rendered by mentioned_users could equal the number of members in a channel which would be slow but could in more extreme case crash the page and/or server.
When validating with a dynamic set of values, especially one that might change during runtime, we should use a lambda or a proc to ensure that the validation uses the most up-to-date set of values. This is particularly important when using config.eager_load = true, which can cause some elements to be loaded only once at startup, thus not reflecting changes made at runtime.
This was the root cause of the issues here, as we were adding more ReviewableScore types after initial load through: `register_reviewable_type Chat::ReviewableMessage`
This PR is a reworked version of https://github.com/discourse/discourse/pull/24670.
In chat, we need the ability to have several notifications per `chat_mention`.
Currently, we have one_to_one relationship between `chat_mentions` and `notifications`:
d7a09fb08d/plugins/chat/app/models/chat/mention.rb (L9)
We want to have one_to_many relationship. This PR implements that by introducing
a join table between `chat_mentions` and `notifications`.
The main motivation for this is that we want to solve some performance problems
with mentions that we're having now. Let's say a user sends a message with @ all
in a channel with 50 members, we do two things in this case at the moment:
- create 50 chat_mentions
- create 50 notifications
We don't want to change how notifications work in core, but we want to be more
efficient in chat, and create only 1 `chat_mention` which would link to 50 notifications.
Also note, that on the side of notifications, having a lot of notifications is not so
big problem, because notifications processing can be queued.
Apart from improving performance, this change will make the code design better.
Note that I've marked the old `chat_mention.notification_id` column as ignored, but
I'm not deleting it in this PR. We'll delete it later in https://github.com/discourse/discourse/pull/24800.
This commit adds a new "My threads" link in sidebar and drawer. This link will open the "/chat/threads" page which contains all threads where the current user is a member. It's ordered by activity (unread and then last message created).
Moreover, the threads list of a channel page is now showing every threads of a channel, and not just the ones where you are a member.
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 previous query would look at the existing messages, count them, and update the associated thread.
But, if for some reason messages were **ALL** deleted without updating the `replies_count`, then the query wouldn't find any message, and wouldn't update any thread's `replies_count`.
In other kind of channels we will only unfollow but for group channels we don't want people to keep appearing in members list.
This commit also creates appropriate services:
- `Chat::LeaveChannel`
- `Chat::UnfollowChannel`
And dedicated endpoint for unfollow: `DELETE /chat/api/channels/:id/memberships/me/follows`
This bug was very reproducible when your last read was a message you didn't read and an admin would delete it. When coming back to the channel you would get a not found, in this case we will now reset last read and present you the last message of the channel.
We could be more fancy and try to detect the next readable message but that would be more code and complexity for such a rare case.
Chat will now check for the state of `SiteSetting.private_email` when sending the summary, when enabled, the mail will not display user information, channel information other than the ID and no message information, only the count of messages.
Mentions and other post processing (like images) are still done asynchronously in the background. This should ensure reloading a channel while the message has not been processed yet doesn’t renders a blank message.
As a followup, we could probably simplify the staged message logic, given we have the new cooked on send.
