This fixes a longstanding TODO to move the contents of the
UpdateUserCountsForChannels job to the ensure_consistency!
method of Chat::Channel, which runs every 15 mins as part of
periodical updates.
This commit also addresses the performance issue of the original,
where we would fetch all channels and do an individual query to
get the count and update the count of each one. Now we do it all
in one query, and only publish the changed channels to the UI.
This will be used when we move the channel creation for DMs
to happen when we first send a message in a DM channel to avoid
a double-request. For now we can just have a new API endpoint
for creating this that the existing frontend code can use,
that uses the new service pattern.
This also uses the new policy pattern for services where the policy
can be defined in a class so a more dynamic reason for the policy
failing can be sent to the controller.

Enabling/Disabling threading has been possible through command line until now. This commit introduces two new UIs:
- When creating a channel, it will be available once the category has been selected
- On the settings page of a channel for admins
Whenever a user opens a channel or marks it read, we now
update the last_viewed_at datetime for that channel membership
record. This is so we will be able to show thread unread indicators
in the channel sidebar that clear independently of the main thread
unread indicators. This unread functionality will follow in another
PR.

We can just use the rich excerpt everywhere since we know
we don't need text_entities -- that introduced security issues
just to fix a spec.

This commit fixes an N1 for mentions/user status
when querying chat threads. This only happened if
any of the thread OMs had mentions.
* FEATURE: Sort thread list by unread threads first
This commit changes the thread list to show the threads that
have unread messages at the top of the list sorted by the
last reply date + time, then all other threads sorted by
last reply date + time.
This also fixes some issues by removing the last_reply
relationship on the thread, which did not work for complex
querying scenarios because its order would be discarded.
* FIX: Various fixes for thread list loading
* Use the channel.threadsManager and find the channel first rather
than use activeChannel in the threads manager, otherwise we may
be looking at differenct channels.
* Look at threadsManager directly instead of storing result for threads
list otherwise it can get out of sync because of replace: true in
other places we are loading threads into the store.
* Fix sorting for thread.last_reply, needed a resort.
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.
To export chat messages, go to `/admin/plugins/chat` and click the Create export
button in the _Export chat messages_ section. You'll receive a direct message
when the export is finished.
Currently, this exports all messages from the last 6 months, but not more than
10000 messages.
This exports all chat messages, including messages from private channels and
users' direct conversations. This also exports messages that were deleted.
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
image image
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.

Since we created user_chat_thread_memberships in
cc2570f we haven't
yet backfilled it for users who previously sent a message in
in threads -- this migration creates the UserChatThreadMemberships
needed for those threads, making sure the last read message id
is accurate for those participants.
* 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'
This fixes an issue where a user could send an empty
string as a chat message .e.g ' ' and the message would
be posted. We don't want this, we need to strip the message
first before validating for length etc.
We were calling reset without the proper params which was causing errors in the console. This commit does the following changes:
- ensures `composer.cancel()` is the only way to cancel editing/reply
- adds a `draftSaved` property to chat message to allow for better tests
- writes a spec to ensure the flow is correct
- adds more page objects for better tests
- homogenize the default state of objects on chat message

Followup 55ef2d0698.
In the cases where the user has no last_read_message_id for
a channel, we want to make sure that a page_size is set for
the ChannelViewBuilder + MessagesQuery, otherwise we end up
loading way more messages than needed (the additional message
loading was fixed in the last commit).
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.
* Moved the settings cog from thread list to thread and
put it in a new header component
* Remove thread original message component, no longer needed
and the list item and thread indicator styles/content
will be quite different
* Start adding content (unread indicator etc.) to the thread
list item and changing structure to be more like designs
* Serialize the last thread reply when opening the thread index,
show in list and update with message bus
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.
#### FIX: Do not use client lastReadMessageId when fetching channel messages
We had an issue where the following happened:
1. User opened channel and saw the last message, and we set the
lastReadMessageId on the server and the client
2. User navigated to another channel
3. Another user deleted the message in the original channel
4. The first user navigated back to the original channel before
the MessageBus event for the deleted message arrived, and got
a 404 error because we were sending the deleted lastReadMessageId as
target_message_id to the channel controller.
Instead of this which is a bit flaky and is hard to cover all
the issues for, instead we can pass a fetch_from_last_read boolean
param to the channels controller, and just get the user's
last_read_message_id straight from the database to use for the
target_message_id. This gets rid of any sources of race conditions
or lack of updates from MessageBus.
#### FIX: Include missing memberships for thread tracking publish
When we publish the channel/message tracking state for a
user and that message was a thread reply the publisher
was erroring because we were not telling Chat::TrackingStateReportQuery
to return missing memberships (which have zeroed out unread counts)
as well, which is what we do for the channel tracking state here.
Also just make sure that the TrackingStateReport does not error
when passed an ID it doesn't have data for.
This commit follows up b6c5a2da08
by serializing the user's thread memberships in these cases:
1. When we do the initial channel fetch with messages, we get
all threads and all the user's thread memberships for those
messages.
2. When the thread list is fetched, we get all the user's memberships
in that list.
3. When the single thread is fetched, either from opening it from
the list, an OM indicator, or just from doing .find() on the
manager when a new MessageBus message comes in
This will let us track the lastReadMessageId on the client, and
will also let us fix an issue where the unread indicator in the
channel header was incrementing for every thread that got a
new message, regardless of whether the user was a member.
This patch introduces policy objects to chat services. It allows putting
more complex logic in a dedicated class, which will make services
thinner. It also allows providing a reason why the policy failed.
Some change has been made to the service runner too to use more easily
these new policy objects: when matching a failing policy (or any failing
step actually), the result object is now provided to the block. This
way, instead of having to access the reason why the policy failed by
doing `result["result.policy.policy_name"].reason` inside the block,
this one can be simply written like this:
```ruby
on_failed_policy(:policy_name) { |policy| policy.reason }
```
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
In the ChannelViewBuilder, we introduced a check to see if
the target message exists, which errors if the message has
been trashed. However if the user is the creator of the message
or admin then they are able to see trashed messages, so
we need to take this into account.
Followup to c908eeacc9
Instead of using the latest message ID in the channel, which
could cause issues if you have an earlier last read message ID
that matches the deleted one, instead we use the first non-deleted
message that comes before the deleted message by ID.
Followup ae3231e140, when a
message is trashed we already update the lastReadMessageId of
all users in the channel to the latest non-deleted message on
the server side. However we didn't propagate this to the client,
so in some cases when we did the following:
1. Delete the last message in the channel
2. Switch to another channel
3. Switch back to the original
We would get a 404 error from the target message ID being looked
up still being the old lastReadMessageId (now deleted) for the
user's channel membership.
All we need to do is send the last not-deleted message ID for
the channel (or thread) to all the member users.
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.
Regressed in eec10efc3d. It means that backend plugin spec failures in CI were not failing the spec suite.
Fixes recent regressions and skips two of them - to be handled next week.

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.
A chat message may be restored later, so we shouldn't be deleting `chat_mentions` records for it.
But we still have to remove notifications (see 082cd139).
When the user sends a message in a thread, we want to
create a membership for them in the background (default
to notification level of Watching) so we can track whether
they have read the thread.
Then, for now since we don't have granular message reading/
scrolling in the thread panel, we just update the thread
last_read_message_id for the user to the latest reply in the
thread when they open the thread panel. This at least will
mark the thread as read.
In future PRs we want to show the blue dot indicator in various
places in the UI for unread threads which will also require
some MessageBus functionality.
This takes into account the same issue fixed for channels
in ae3231e140
When setting DISCOURSE_ZEITWERK_EAGER_LOAD=1 to enable
eager loading the previous solution to adding chat_levels
to the core NotificationLevels would break with a module
loading error (c.f. cc2570fce3)
We don't actually _need_ to extend the core class, we can just
make our own for chat, let's do this instead.
This will enable us to begin work on user tracking
state for a thread so we can show thread-specific
unreads and mentions indicators. In this case are following
the core notification_level paradigm rather than the solution
UserChatChannelMembership went with, and eventually we
will want to refactor the other table to match this as well.

Since we have channel message retention which deletes
messages, we can end up with cases where the thread
is still around but the message is deleted. We will
handle the cascade delete in a different commit --
for now we will ensure the thread list lookup handles
this case and doesn't error.
After this change, in order to join a chat channel, a user needs to be in a group with at least “Reply” permission for the category. If the user only has “See” permission, they are able to preview the channel, but not join it or send messages. The auto-join function also follows this new restriction.

This commit adds an initial thread list UI. There are several limitations
with this that will be addressed in future PRs:
* There is no MessageBus reactivity, so e.g. if someone edits the original
message of the thread it will not be reflected in the list. However if
the thread title is updated the original message indicator will be updated.
* There is no unread functionality for threads in the list, if new messages
come into the thread there is no indicator in the UI.
* There is no unread indicator on the actual button to open the thread list.
* No pagination.
In saying that, this is the functionality so far:
* We show a list of the 50 threads that the user has most recently participated
in (i.e. sent a message) for the channel in descending order.
* Each thread we show a rich excerpt, the title, and the user who is the OM creator.
* The title is editable by staff and by the OM creator.
* Thread indicators show a title. We also replace emojis in the titles.
* Thread list works in the drawer/mobile.
- `ChatChannel`
- `UserChatChannelMembership`
Also creates a new `chat-direct-message` model used as the object for the`chatable` property of the `ChatChannel` when the `ChatChannel` is a direct message channel. When the chatable is a category a real `Category` object will now be returned.
Archive state of a `ChatChannel` is now hold in a `ChatChannelArchive` object.
When we were deleting messages in chat, we would find all of
the UserChatChannelMembership records that had a matching
last_read_message_id and set that column to NULL.
This became an issue when multiple users had that deleted message
set to their last_read_message_id. When we called ChannelUnreadsQuery
to get the unread count for each of the user's channels, we were
COALESCing the last_read_message_id and returning 0 if it was NULL,
which meant that the unread count for the channel would be the total
count of the messages not sent by the user in that channel.
This was particularly noticeable for DM channels since we show
the count with the indicator in the header. This issue would disappear
as soon as the user opened the problem channel, because we would then
set the last_read_message_id to an actual ID.
To circumvent this, instead of NULLifying the last_read_message_id in
most cases, it makes more sense to just set it to the most recent
non-deleted chat message ID for the channel. The only time it will
be set to NULL now is when there are no more other messages in the
channel.
We need to create and update `chat_mentions` records for messages earlier. They should be created or updated before we call `Chat::Publisher.publish_new!` `Chat::Publisher.publish_edit!` to send the message to message bus subscribers).
This logic is covered with tests in `message_creator_spec.rb`, `message_updater_spec.rb`, `notifier_spec.rb` and `notify_mentioned_spec.rb`.
See the commits history for steps of refactoring.
