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.

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."
