We usually don't enforce foreign key relationships on the database level.
Because of that, occasionally it's possible to see a chat message that
references to a non-existent chat_channel or user. MessagesExporter
failed in such case before, this PR fixes that.
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 adds the following chat metrics:
- _chat_open_channels_with_threads_enabled_ — a count of open channels
where threading is enabled.
- _chat_channel_messages_ — a count of messages sent in a chat channel
(i.e. not a personal chat / direct message), within a thread or outside of a thread.
- _chat_threaded_messages_ — a count of messages sent within a thread
in a chat channel (i.e. not a personal chat / direct messages).
- _chat_direct_messages_ — a count of messages sent in a personal chat / direct messages.
The metrics added using the plugin API introduced in 098ab29d,
and extended in d91456fd.
Note that these stats won't be exposed at the `about.json`
and the `site/statistics.json` routes.
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.
Introduces the concept of image thumbnails in chat, prior to this we uploaded and used full size chat images within channels and direct messages.
The following changes are covered:
- Post processing of image uploads to create the thumbnail within Chat::MessageProcessor
- Extract responsive image ratios into CookedProcessorMixin (used for creating upload variations)
- Add thumbnail to upload serializer from plugin.rb
- Convert chat upload template to glimmer component using .gjs format
- Use thumbnail image within chat upload component (stores full size img in orig-src data attribute)
- Old uploads which don't have thumbnails will fallback to full size images in channels/DMs
- Update Magnific lightbox to use full size image when clicked
- Update Glimmer lightbox to use full size image (enables zooming for chat images)
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
We're seeing some deprecation warnings in production. This is because we're passing a raw Ruby timestamp, which gets stringified implicitly when written to Redis. As per #15842, this conversion needs to be done explicitly.
This PR introduces thread support for channel archives. Now, threaded messages are rendered inside a `details` HTML tag in posts.
The transcript markdown rules now support two new attributes: `threadId` and `threadTitle`.
- If `threadId` is present, all nested `chat` tags are rendered inside the first one.
- `threadTitle` (optional) defines the summary content.
```
[chat threadId=19 ... ]
thread OM
[chat ... ]
thread reply
[/chat]
[/chat]
```
If threads are split across multiple posts when archiving, the range of messages in each part will be displayed alongside the thread title. For example: `(message 1 to 16 of 20)` and `(message 17 to 20 of 20)`.
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.
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
This adds the ability to collect stats without exposing them
among other stats via API.
The most important thing I wanted to achieve is to provide
an API where stats are not exposed by default, and a developer
has to explicitly specify that they should be
exposed (`expose_via_api: true`). Implementing an opposite
solution would be simpler, but that's less safe in terms of
potential security issues.
When working on this, I had to refactor the current solution.
I would go even further with the refactoring, but the next steps
seem to be going too far in changing the solution we have,
and that would also take more time. Two things that can be
improved in the future:
1. Data structures for holding stats can be further improved
2. Core stats are hard-coded in the About template (it's hard
to fix it without correcting data structures first, see point 1):
63a0700d45/app/views/about/index.html.erb (L61-L101)
The most significant refactorings are:
1. Introducing the `Stat` model
2. Aligning the way the core and the plugin stats' are registered
There is an edge case where the following occurs:
1. The user sets a bookmark reminder on a post/topic
2. The post/topic is changed to a PM before or after the reminder
fires, and the notification remains unread by the user
3. The user opens their bookmark reminder notification list
and they can still see the notification even though they cannot
access the topic anymore
There is a very low chance for information leaking here, since
the only thing that could be exposed is the topic title if it
changes to something sensitive.
This commit filters the bookmark unread notifications by using
the bookmarkable can_see? methods and also prevents sending
reminder notifications for bookmarks the user can no longer see.
This commit starts from a simple observation: cooking messages on the hot path can be slow. Especially with a lot of mentions.
To move cooking from the hot path, this commit has made the following changes:
- updating cooked, inserting mentions and notifying user of new mentions has been moved inside the `process_message` job. It happens right after the `Chat::MessageProcessor` run, which is where the cooking happens.
- the similar existing code in `rebake!` has also been moved to rely on the `process_message`job only
- refactored `create_mentions` and `update_mentions` into one single `upsert_mentions` which can be called invariably
- allows services to decide if their job is ran inline or later. It avoids to need to know you have to use `Jobs.run_immediately!` in this case, in tests it will be inline per default
- made various frontend changes to make the chat-channel component lifecycle clearer. we had to handle `did-update @channel` which was super awkward and creating bugs with listeners which the changes of the PR made clear in failing specs
- adds a new `-processed` (and `-not-processed`) class on the chat message, this is made to have a good lifecyle hook in system specs
This is a follow-up to e6299a3. I additionally fixed these three things:
1. Since e6299a3 there's no need anymore to join the group_users table
when looking for users who were reached by a group mention, so
I removed that join in that commit. But turned out we were joining
the group_users table twice, so I removed the second join in this PR.
That drastically speeded up my test query, from 6 sec to 0.26 sec.
2. We also were joining twice the user_chat_channel_memebership table,
so I removed the second unnecessary join too.
3. We actually need to join the user_chat_channel_memebership table
only in certain cases, and we don't need to do that for group mentions,
so I fixed that too.
As a result of these changes, time of my test query fall down from
6 sec to 0.001 sec. And the resulting SQL query now contains only
one JOIN statement.
A follow-up to faac6773. This PR eliminates one more heavy join by forcing
Active Record to do two queries instead.
Also, along the way, I made this change:
```
# this generates two quries to the groups table
def groups_to_mention
@groups_to_mention = mentionable_groups - groups_with_too_many_members
end
# so I changed it to (this makes only one query to the groups table):
def groups_to_mention
@groups_to_mention ||= mentionable_groups.where("user_count <= ?", SiteSetting.max_users_notified_per_group_mention)
end
```
This one is kind of a premature optimization, because we don't have evidence that
this extra query is a problem, but it seems cleaner this way.
Commits history on this PR may help better understand the change.
Add new chat indicator preference within chat user preferences.
Enabling this option will mean that green notifications will only appear for mentions (within channels and DMs.
This change also enables mentions within direct messages.
This change allows users to edit their chat messages based on the criteria added to Site Settings.
If the grace period conditions are met then there will be no (edited) text applied to the message.
The following site settings are added to chat:
chat editing grace period (seconds since message created)
chat editing grace period max diff for low trust levels (number of characters changed)
chat editing grace period max diff for high trust levels (number of characters changed)
This feature adds notifications for chat messages that are sent within personal chats (1:1 and personal group chats).
To prevent notification spam we make use of consolidated notifications to combine updated message information in a meaningful way that allows the receiver to quickly jump into the chat to see what they missed.
This update respects muted channels, muted and blocked users. It will only create a new notification when the user has not muted the channel and the notified user is not muting or ignoring the message sender.
Currently, the logic for creating a new chat message is scattered
between a controller and an “old” service.
This patch address this issue by creating a new service (using the “new”
sevice object system) encapsulating all the necessary logic.
(authorization, publishing events, etc.)
- moves the onebox logic away from `plugin.rb` to a new `onebox_handler` lib
- splits the `discourse_chat_message` template into two: one for channels, and one for messages
- refactors the logic code slightly to send only the necessary arguments to each template
This commit shouldn't change end-user behavior.
This PR swaps out the custom pathway to publishing and rendering mention warnings after a message is sent.
ChatPublisher#publish_notice is used, and expanded. Now, instead of only accepting text_content as an argument, component and component_args are accepted and there is a renderer for these components.
Translations moved to server, as notices expect text to be passed in unless a component is rendered
The warnings are rendered at the top now, outside of the scope of the single message that sent it.
I entirely removed the jit_messages_spec b/c it's duplicate testing of other parts of the app. IMO we don't need a backend test for a feature, a component test for the feature AND a system test (that is slow and potentially even flakey due to timing issues with wait) to test the same thing. So jit_messages_spec is gone.
In #22914 we added a fix to stop creating reviewables in the review queue when flagging a chat message and choosing the "notify user" option. By mistake we also stopped creating it when selecting the "something else" option.
This change makes it so a "something else" flag once again creates a reviewable. (Same behaviour as posts.)
This is also fixes the issue of chat composer warnings persisting across channels. Currently if you try to mention more groups than is allowed for example, a mention warning pops up. When you change channels the mention warning will not disappear even if there is no text in the composer.
This adds a reset function to the chat-composer-warnings-tracker.js, which is called when the channel is changed and the message is empty. In the event that the message is not empty we call captureMentions to check the loaded drafts' mentions.
This PR would be nicer if the post-send notice used the new chat notices API to publish the mention warnings but we would have to change the existing ones and I thought that would be too much change for this PR. It'd be a good followup though.
This commit removes any logic in the app and in specs around
enable_experimental_hashtag_autocomplete and deletes some
old category hashtag code that is no longer necessary.
It also adds a `slug_ref` category instance method, which
will generate a reference like `parent:child` for a category,
with an optional depth, which hashtags use. Also refactors
PostRevisor which was using CategoryHashtagDataSource directly
which is a no-no.
Deletes the old hashtag markdown rule as well.
We did some testing and saw that making one query per month is
cheaper than querying all chat messages at ones. Note that even
though the export job will be performing one query per month,
the exported messages will be streamed into a single CSV file, so
nothing changes from the user's point of view.
This is extracted from #22390.
This patch introduces a scope to avoid duplication and a new method,
`Chat::Channel.find_by_id_or_slug` to allow finding a channel either by
its id or by its slug (or its category slug).
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 is extracted from #22390.
This patch simplifies a little how we handle uploads in chat, relying on
ActiveRecord mechanisms instead of calling custom methods.
This also makes `Chat::Message#validate_message` a “real” AR validation,
meaning it will run automatically when `#valid?` is called.
This only moves code around and doesn't change any behavior. This does two things:
1. Extracts the `channel.joined_by?` methods
2. Uses term "members" instead of "participants" for chat members
Turns out making a html4 fragment and then operating on parts of it using html5 fragments is a bad idea. ;)
This seems to fix the issue with occasionally missing GH icons in oneboxes.
Someone who cannot chat is also not able to join chat channels,
so we may not check all the time user.can_chat? && user.can_join_chat_channel?
and just call user.can_join_chat_channel? instead.
We need a nice way to only return some hashtag data
sources based on various site settings. This commit
adds an enabled? method that every hashtag data source
must implement. If this returns false the data source
will not be used at all for hashtag lookups or search.
It could only occur on message created by the user itself and deleted while the user was looking at the channel.
It more generally fix the trash service which was not correctly setting the author of the delete.
`SiteSetting.enable_public_channels` allows site admin to decide if public channels are available at all. There's no distinction between admins or not as we expect admins to create private category channels if they want to limit usage.
Initial migration and changes to models as well as
changing the following services to update last_message_id:
* Chat::MessageCreator
* Chat::RestoreMessage
* Chat::TrashMessage
The data migration will set the `last_message_id` for all existing
threads and channels in the database.
When we query the thread list as well as the channel,
we look at the last message ID for the following:
* Channel - Sorting DM channels, and channel metadata for the list of channels
* Thread - Last reply details for thread indicators and thread list
This commit makes sure we don't load all data into memory when doing CSV exports.
The most important change here made to the recently introduced export of chat
messages (3ea31f4). We were loading all data into memory in the first version, with
this commit it's not the case anymore.
Speaking of old exports. Some of them already use find_each, and it worked as
expected, without loading all data into memory. And it will proceed working as
expected after this commit.
In general, I made sure this change didn't break other CSV exports, first manually, and
then by writing system specs for them. Sadly, I haven't managed yet to make those
specs stable, they work fine locally, but flaky in GitHub actions, so I've disabled them
for now.
I'll be making more changes to the CSV exports code soon, those system specs will be
very helpful. I'll be running them locally, and I hope I'll manage to make them stable
while doing that work.
Trying to fix two issues:
1. Sometimes the publish_new! event for update_thread_original_message
finishes running on the UI before the one for thread_created, in this
case we just want to do nothing because thread_created will fetch the
new thread along with its preview from the server if needed
2. Sometimes the thread GET and /read events were erroring because
last_reply on the thread was nil, this was potentially occuring because
the thread_created event was coming through to the UI before the rest
of MessageCreator was done, so we just move that after the big update
to set thread_id for the new and existing messages in the reply
chain
This commit replaces two existing screens:
- draft
- channel selection modal
Main features compared to existing solutions
- features are now combined, meaning you can for example create multi users DM
- it will show users with chat disabled
- it shows unread state
- hopefully a better look/feel
- lots of small details and fixes...
Other noticeable fixes
- starting a DM with a user, even from the user card and clicking <kbd>Chat</kbd> will not show a green dot for the target user (or even the channel) until a message is actually sent
- it should almost never do a full page reload anymore

Followup to 3f1024de76
The ActiveModel::Types.register(:array) call for chat was
called too late in the Zeitwerk load order in production,
causing this error:
> `lookup': Unknown type :array (ArgumentError)
> raise ArgumentError, "Unknown type #{symbol.inspect}"
> ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
We need to load the type and register it manually before the rest
of the chat files are loaded via the engine and Zeitwerk.
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.

* 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.
This small patch registers a new `ActiveModel` type: `array`.
It will split a string on `,` to create a new array. If the value is
already an array, nothing will happen and for all other types, it will
wrap the value in an array.
Here’s an example on an existing contract:
```ruby
attribute :target_usernames
before_validation do
self.target_usernames =
(
if target_usernames.is_a?(String)
target_usernames.split(",")
else
target_usernames
end
)
end
# can be rewritten as:
attribute :target_usernames, :array
```
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.
We had a bug in this code recently, sometimes users saw weird notifications
like:
User mentioned all_mentioned_user_ids in the help chat channel
We fixed that bug in b85d057.
This refactoring is a follow-up to that fix. As that bug showed, it’s quite easy
to introduce a key that may end up being sent to the `NotifyMentioned` job,
which can lead to such weird notifications. This refactoring makes sure that
the `to_notify` hash contains only IDs of users that should be notified about
mentions.
Previously this was defining methods like `UserOption#never?`, `UserOption#all_new?`, `UserOption#dm_and_mentions?`. Now they will be prefixed like `UserOption#chat_header_indicator_never?`
Unfortunately, Discourse's `UserOption` model is not currently autoloaded. That means that modifying it via a `reloadable_patch` will try to apply the changes repeatedly. Normally this doesn't matter since the changes are idempotent. However, introducing ActiveRecord enums is not idempotent - they raise an error if the same enum already exists on the model. This commit adds a check to avoid hitting this 'duplicate definition' error.
Reproduced
```
rails runner 'Rails.application.reloader.reload!'
```
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.

When a thread is created / a new message is created in the
thread, we want to make sure that the original message user
has a membership for that thread, otherwise they will not
receive unread indicators for messages in the thread.
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 makes some fundamental changes to how hashtag cooking and
icon generation works in the new experimental hashtag autocomplete mode.
Previously we cooked the appropriate SVG icon with the cooked hashtag,
though this has proved inflexible especially for theming purposes.
Instead, we now cook a data-ID attribute with the hashtag and add a new
span as an icon placeholder. This is replaced on the client side with an
icon (or a square span in the case of categories) on the client side via
the decorateCooked API for posts and chat messages.
This client side logic uses the generated hashtag, category, and channel
CSS classes added in a previous commit.
This is missing changes to the sidebar to use the new generated CSS
classes and also colors and the split square for categories in the
hashtag autocomplete menu -- I will tackle this in a separate PR so it
is clearer.
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 follow-up to 54b2a85b. That commit didn't fix the issue because the to_notify hash that we return from the notify_edit method isn't used anywhere apart from tests (that's confusing, we're going to fix that soon).
In the past, we create a `chat_mention` records only when we wanted to notify a user about a mention. Since we don't send notifications when a user mentioning himself, we didn't create a `chat_mention` records in those cases.
Now we use `chat_mentions` records in other scenarios too, so when a user is mentioning himself we want to:
1. Create a `chat_mention` record for that mention
2. Do not create a notification for that mention
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.

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.
When making the list of users to notify we set `all_mentioned_user_ids` key on the `to_notify` Hash.
This hash will be passed around until the actual moment where we send the notifications:
```ruby
identifier_text =
case identifier_type
when :here_mentions
"@here"
when :global_mentions
"@all"
when :direct_mentions
""
else
"@#{identifier_type}"
end
```
As not found `all_mentioned_user_ids` would end up being sent as `@all_mentioned_user_ids` which is obviously incorrect.
This commit is a direct fix to the issue and will remove the key as soon as we have used it sooner up in the chain.
This bug was reproducible when doing this sequence of events:
- create a message with a direct mention: `@bob hi`
- edit this message into a global mention `@all hi`
Every replies creates a thread, even when threading is disabled. This is how we ensure we can go back and forth. However, a message bus event should only be published when threading is enabled, otherwise frontend will attempt to display a thread which is not possible when disabled.
This fixes a silent background 404 when doing a reply in a direct message channel or a non threading enabled category channel.
What is the problem?
Previously, this was the query used to move change messages into another
channel.
```
INSERT INTO chat_messages(
chat_channel_id, user_id, last_editor_id, message, cooked, cooked_version, created_at, updated_at
)
SELECT :destination_channel_id,
user_id,
last_editor_id,
message,
cooked,
cooked_version,
CLOCK_TIMESTAMP(),
CLOCK_TIMESTAMP()
FROM chat_messages
WHERE id IN (:message_ids)
RETURNING id
```
The problem is that this incorrectly assumes that the insertion will be based on the order of `message_ids`. However, that
is not the case as PostgreSQL provides no such guarantee. Instead we need to explicitly order the messages to ensure
the right order of insertion.
This problem was discovered by a flaky test which exposed the non-guarantee order of insertion.
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.
This commit implements all the necessary logic to create thread seamlessly. For this it relies on the same logic used for messages and generates a `staged-id`(using the format: `staged-thread-CHANNEL_ID-MESSAGE_ID` which is used to re-conciliate state client sides once the thread has been persisted on the backend.
Part of this change the client side is now always using real thread and channel objects instead of sometimes relying on a flat `threadId` or `channelId`.
This PR also brings three UX changes:
- thread starts from top
- number of buttons on message actions is dependent of the width of the enclosing container
- <kbd>shift + ArrowUp</kbd> will reply to the last message
This was reverted in 38cebd3ed5.
The issue was that I was using Discourse.redis.delete_prefixed
which does a slow redis KEYS lookup, which is not advised in
production. This commit removes that, and also ensures the periodical
thread count update only happens if threading is enabled.
I changed to use a redis INCR/DECR for reply count
cache. This avoids a round trip to redis to GET the current
count, and also avoids multi-process issues, where
if there's two processes trying to increment at the
same time, they may both receive the same value, add one
to it, then both write the same value back.
Then, it's only n+1 instead of n+2.
This also prevents almost all chat scheduled jobs from
running if chat is disabled, the only one remaining is
the message retention job.
This commit moves the category channel creation out
of the Chat::Api::Channel controller and into a
dedicated CreateCategoryChannel service. A follow up
commit will move the DM channel creation out of
the old DirectMessageChannelCreator service.
Also includes a new on_model_errors helper
for chat service class usage, that collects model
validation errors to present in a nice way.

Steps to reproduce the bug:
1. Send a chat message
2. Edit the message and add a mention to it
3. The mentioned user won't receive a notification
This PR fixes the problem.
Also:
1. There's no need anymore to have a code for removing notifications in the `notify_edit` method, because a call to `@chat_message.update_mentions` in the first line of the `notify_edit` method does that job:
ff56f403a2/plugins/chat/lib/chat/notifier.rb (L90)
2. There's no need to load mention records from database, it's enough to pluck user ids
This is to help generate random channels and chat
messages for local dev. This was removed in 12a18d4d55
presumably because it was not worth refactoring at the
time.
I've only added these tasks:
- `rake chat:message:populate\[113,20\]` (channel_id, count)
- Generates the count of messages for a channel ID provided,
otherwise uses a random channel and 200 count.
- `rake chat:category_channel:populate`
- Creates a chat channel for a random category.
- `rake chat🧵populate\[132,5\]` (channel_id, message_count)
- Creates a thread with N messages in the specified channel,
and enables threading in that channel if necessary
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.
We've found these exceptions in logs:
Job exception: undefined method `destroy!' for nil:NilClass

In the past, we were creating `chat_mention` records only for sending notifications, so every mention record had a related notification. It isn't the case anymore (since fa543cda). This PR fixes the problem by making sure the notification exists before trying to remove it. Also, we shouldn't be deleting a `chat_mention` record itself, only a notification, this PR fixes that too.
It's quite hard to reproduce this bug locally, I wasn't able to do so, the logic in this class is quite complicated, that's why I'm not adding a test. Also, when looking at this I realized that this method isn't in a fully correct state now, I suspect sometimes some notifications may not be delivered after someone edits a chat message and adds new mentions to it. I'm going to refactor and simplify the method in a subsequent PR.
This commit introduces a redis cache over the top of the thread
replies_count DB cache, so that we can quickly and accurately
increment/decrement the reply count for all users and not have
to constantly update the database-level count. This is done so
the UI can have a count that is displayed to the users on each
thread indicator, that appears to live update on each chat
message create/trash/recover inside the thread.
This commit also introduces the `Chat::RestoreMessage` service
and moves the restore endpoint into the `Api::ChannelMessages`
controller as part of incremental migrations to move things out
of ChatController.
Finally, this commit refactors `Chat::Publisher` to be less repetitive
with its `MessageBus` sending code.
