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.
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)
```
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 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.
Group channels will allow users to create channels with a name and invite people. It's possible to add people even after creation of the channel. Removing users is not yet possible but will be added in the near future.
Technically a group channel is `direct_message_channel` with a group attribute set to true on its direct message (chatable). This model might evolve in the future but offers much flexibility for now without having to rely on a complex migration.
The commit essentially consists of:
- a migration to set existing direct message channels with more than 2 users to a group
- a new message creator which allows to search, add members, and create groups
- a new `AddUsersToChannel` service
- a modified `SearchChatable` service
Workaround for an issue we are experiencing on thread index frontend where thread loads participants correctly (up to 10), then refreshes the threads and then limits to 3 participants.
There is an issue with storing threads for the main channel view and the thread list in the same store so handling the max participants on the frontend is a workaround until channel.threadsManager is updated.
I've adjusted the tests to handle the additional data being returned from ThreadParticipantQuery.
UX changes to thread item:
- drop "last reply" timestamp copy
- drop last reply excerpt
- show up 9+OP members

Prior to this commit we were loading a large number of thread messages without any pagination. This commit attempts to fix this and also improves the following points:
- code sharing between channels and threads:
Attempts to reuse/share the code use in channels for threads. To make it possible part of this code has been extracted in dedicated helpers or has been improved to reduce the duplication needed.
Examples of extracted helpers:
- `stackingContextFix`: the ios hack for rendering bug when momentum scrolling is interrupted
- `scrollListToMessage`, `scrollListToTop`, `scrollListToBottom`: a series of helper to correctly scroll to a specific position in the list of messages
- better general performance of listing messages:
One of the main changes which has been made is to remove the computation of visible message during scroll, it will only happen when needed (update last read for example). This constant recomputation of `message.visible` on intersection observer event while scrolling was consuming a lot of CPU time.
This commit makes it so that when the user has unread threads
for a channel we show a blue dot in the sidebar (or channel index
for mobile/drawer).
This blue dot is slightly different from the channel unread messages:
1. It will only show if the new thread messages were created since
the user last viewed the channel
2. It will be cleared when the user views the channel, but the threads
are still considered unread because we want the user to click into
the thread list to view them
This necessitates a change to the current user serializer to also
include the unread thread overview, which is all unread threads
across all channels and their last reply date + time.
This commit includes several fixes and improvements to thread
original message handling:
1. When a thread's original message is deleted, the thread no longer
counts as unread for a user
2. When a thread original message is deleted and the user is looking
at the thread list, it will be removed from the list
3. When a thread original message is restored and the user is looking
at the thread list, it will be added back to the list if it was
previously loaded
This PR adds a new parameter to fetch chat messages: `target_date`.
It can be used to fetch messages by a specific date string. Note that it does not need to be the `created_at` date of an existing message, it can be any date. Similar to `target_message_id`, it retrieves an array of past and future messages following the query limits.
This commit adds a tracking dropdown to each individual thread, similar to topics,
that allows the user to change the notification level for a thread manually. Previously
the user had to reply to a thread to track it and see unread indicators.
Since the user can now manually track threads, the thread index has also been changed
to only show threads that the user is a member of, rather than threads that they had sent
messages in.
Unread indicators also respect the notification level -- Normal level thread tracking
will not show unread indicators in the UI when new messages are sent in the thread.
This commit adds the initial part of thread indicator improvements:
* Show the reply count, last reply date and excerpt,
and the participants of the thread's avatars and
count of additional participants
* Add a participants component for the thread that
can be reused for the list
* Add a query class to get the thread participants
* Live update the thread indicator more consistently
with the last reply and participant details

In subsequent PRs we will cache the participants since
they do not change often, and improve the thread list
further with participants.
This commit also adds a showPresence boolean (default
true) to ChatUserAvatar, since we don't want to show the
online indicator for thread participants.

This commit attempts to fix the case where the messages loaded initially don't fill the screen. It would prevent user to scroll and as a result to load more.
There are multiple fixes in this commit:
- the main fix is removing this code which was preventing the actual fill:
```javascript
// prevents an edge case where user clicks bottom arrow
// just after scrolling to top
if (loadingPast && this.#isAtBottom()) {
return;
}
```
- ensures we always give a page site to the `chatApi.channel(...)` call if we have one, in the current state when `fetchFromLastRead` was `true` we would not set `args.page_size`
- ensures the `query_paginated_messages` is having a valid page size, which is not nil and not > `MAX_PAGE_SIZE`
- write a spec for the autofill, it was a challenging spec to write but it should give us the confidence we need here
Since 5cce829 and the new
channel view builder, we have no need of these obsolete
routes which have way too much logic in the controller, which
has been superseded by the view builder anyway.
Remove the routes and update the channel message loading to use it.
Followup to d4a5b79592,
this introduced an N1 because every message in the list
we had to query users for the mentions and then the user's
status too. Instead we can just include both in Chat::MessagesQuery.
This commit adds the thread index and individual thread
in the index list unread indicators, and wires up the message
bus events to mark the threads as read/unread when:
1. People send a new message in the thread
2. The user marks a thread as read
There are several hacky parts and TODOs to cover before
this is more functional:
1. We need to flesh out the thread scrolling and message
visibility behaviour. Currently if you scroll to the end
of the thread it will just mark the whole thread read
unconditionally.
2. We need to send down the thread current user membership
along with the last read message ID to the client and
update that with read state.
3. We need to handle the sidebar unread dot for when threads
are unread in the channel and clear it based on when the
channel was last viewed.
4. We need to show some indicator of thread unreads on the
thread indicators on original messages.
5. UI improvements to make the experience nicer and more
like the actual design rather than just placeholders.
But, the basic premise around incrementing/decrementing the
thread overview count and showing which thread is unread
in the list is working as intended.
This PR adds status to mentions in chat and makes those mentions receive live updates.
There are known unfinished part in this implementation: when posting a message, status on mentions on that message appears immediately, but only if a user used autocomplete when typing the message. If user copy and paste a message with mentions into chat composer, those mentions won't have user status on them.
PRs with fixes for both problems are following soon.
Preparations for this PR that were made previously include:
- DEV: correct a relationship – a chat message may have several mentions 0dcfd7ddec
- DEV: extract the logic for extracting and expanding mentions from ChatNotifier 75b81b6854
- DEV: Always create chat mention records fa543cda06
- DEV: better split create_notification! and send_notifications logic e292c45924
- DEV: more tests for mentions when updating chat messages e7292e1682
- DEV: extract updating status on mentions into a lib function e49d338c21
- DEV: Create and update chat message mentions earlier 35a414bb38
- DEV: Create a chat_mention record when self mentioning 2703f2311a
- DEV: When deleting a chat message, do not delete mention records f4fde4e49b
This commit moves message lookup and querying to the
/chat/api/channel/:id endpoint and adds the ability
to query the tracking state overview for threads as well
as the threads and thread tracking state for any thread
original messages found.
This will allow us to get an initial overview of thread
tracking for a user when they first enter a channel, rather
than pre-emptively loading N threads and tracking state
for those across all channels on the current user serializer,
which would be expensive.
This initial overview will be used in subsequent PRs to
flesh out the thread unread indicators in the UI.
This also moves many chunks of code that were in services
to reusable Query classes, since use of services inside
services is discouraged.
This moves chat tracking state calculation for channels
and threads into a central Chat::TrackingStateManager service, that
serves a similar purpose to the TopicTrackingState model
in core.
This service calls down to these query classes:
* ThreadUnreadsQuery
* ChannelUnreadsQuery
To get the unread_count and mention_count for the appropriate
channels and threads.
As well as this, this commit refactors the client-side chat
tracking state.
Now, there is a central ChatTrackingStateManager Ember Service
so all tracking is accessible and can be counted from one place,
which can also initialize tracking from an initial payload.
The actual tracking counts are now maintained in a ChatTrackingState
class that is initialized on the `.tracking` property of both channel and
thread objects.
This removes the attributes on UserChatChannelMembership and decoration
of said membership from ChannelFetcher, preferring instead to have an additional
object for tracking in the JSON.
We currently don't have a nice UI to show unread messages for the thread,
and it will take some time to create one. For now, this commit makes it so
new messages inside a thread do not count towards a chat channel's unread
counts, and new messages sent in a thread do not update a user's `last_read_message_id`
for a channel.
In addition, this PR refactors the `Chat::ChannelFetcher` to use the `Chat::ChannelUnreadsQuery`
query class for consistency, and made said class able to return zeroed-out records
for channels the user is not a member of.
Finally, a small bug is fixed here where if a user's `last_read_message_id` for
a channel was a thread's OM ID, then the thread OM would not show in the
main channel stream for them until another reply to the channel was posted.
This commit introduces a Chat::Publisher and MessageBus endpoint
that allows for updating a user's channel tracking state in bulk for
multiple channels, rather than having to do it for one channel
at a time.
This also required an improvement to ChannelUnreadsQuery -- now
multiple channel IDs can be passed to this to get the unread counts
and mention counts for those channels for a user, also increasing
efficiency rather than having to do a query for every individual
channel.
Followup to #20802
This commit main goal was to comply with Zeitwerk and properly rely on autoloading. To achieve this, most resources have been namespaced under the `Chat` module.
- Given all models are now namespaced with `Chat::` and would change the stored types in DB when using polymorphism or STI (single table inheritance), this commit uses various Rails methods to ensure proper class is loaded and the stored name in DB is unchanged, eg: `Chat::Message` model will be stored as `"ChatMessage"`, and `"ChatMessage"` will correctly load `Chat::Message` model.
- Jobs are now using constants only, eg: `Jobs::Chat::Foo` and should only be enqueued this way
Notes:
- This commit also used this opportunity to limit the number of registered css files in plugin.rb
- `discourse_dev` support has been removed within this commit and will be reintroduced later
