Previous commit 479c0a3051 was done with the assumption that this info was defined on user serializer but it was actually defined on post serializer in core. This commit extends the user serializer for messages to add this data to the user.
Also correctly adds serializer test to ensure we actually have this data.
Adds a new LookupThread class that handles finding the
thread based on thread + channel ID, checking permissions
and policy/contract checks.

This commit fixes the UpdateUserLastRead spec which was checking
for a message ID that did not exist -- this could fail at times
since message ID 2 could exist. Better to create + destroy a message
since then it's guaranteed we have a unique ID.
This also attempts to clarify a step that we expect to fail which
succeeds instead by adding another emoji next to the success tick and
an explanation text.
Also removes some uses of unless in Services::Base, we generally prefer
to use alternatives, since unless can be hard to parse in a lot of
cases.

This commit introduces the skeleton of the chat thread UI. The
structure of the components looks like this. Its done this way
so the side panel can be used for other things as well if we wish,
not just for threads:
```
.main-chat-outlet
<ChatLivePane />
<ChatSidePanel>
<-- rendered with {{outlet}} -->
<ChatThread />
</ChatSidePanel>
```
Later on the `ChatThreadList` will be rendered here as well.
Now, when you go to a channel you can open a thread by clicking
on either the Open Thread message action button or by clicking on
the reply indicator. This will take you to a route like `chat/c/:slug/:channelId/t/:threadId`.
This works on mobile as well.
This commit includes basic serializers and routes for threads,
as well as a new `ChatThreadsManager` service in JS that caches
threads for a channel the same way the channel threads manager does.
The chat messages inside the thread are intentionally left out
until a later PR.
**NOTE: These changes are gated behind the site setting enable_experimental_chat_threaded_discussions
and the threading_enabled boolean on a ChatChannel**
We’re now using `contract` as the first step and validations for
mandatory parameters have been added.
To simplify specs a bit, we only assert the service contract is run as
expected without testing each validation case. We’re now testing the
contract itself in isolation.
This is a combined work of Martin Brennan, Loïc Guitaut, and Joffrey Jaffeux.

This commit implements a base service object when working in chat. The documentation is available at https://discourse.github.io/discourse/chat/backend/Chat/Service.html
Generating documentation has been made as part of this commit with a bigger goal in mind of generally making it easier to dive into the chat project.
Working with services generally involves 3 parts:
- The service object itself, which is a series of steps where few of them are specialized (model, transaction, policy)
```ruby
class UpdateAge
include Chat::Service::Base
model :user, :fetch_user
policy :can_see_user
contract
step :update_age
class Contract
attribute :age, :integer
end
def fetch_user(user_id:, **)
User.find_by(id: user_id)
end
def can_see_user(guardian:, **)
guardian.can_see_user(user)
end
def update_age(age:, **)
user.update!(age: age)
end
end
```
- The `with_service` controller helper, handling success and failure of the service within a service and making easy to return proper response to it from the controller
```ruby
def update
with_service(UpdateAge) do
on_success { render_serialized(result.user, BasicUserSerializer, root: "user") }
end
end
```
- Rspec matchers and steps inspector, improving the dev experience while creating specs for a service
```ruby
RSpec.describe(UpdateAge) do
subject(:result) do
described_class.call(guardian: guardian, user_id: user.id, age: age)
end
fab!(:user) { Fabricate(:user) }
fab!(:current_user) { Fabricate(:admin) }
let(:guardian) { Guardian.new(current_user) }
let(:age) { 1 }
it { expect(user.reload.age).to eq(age) }
end
```
Note in case of unexpected failure in your spec, the output will give all the relevant information:
```
1) UpdateAge when no channel_id is given is expected to fail to find a model named 'user'
Failure/Error: it { is_expected.to fail_to_find_a_model(:user) }
Expected model 'foo' (key: 'result.model.user') was not found in the result object.

This change only makes the model reflect correctly what's
already happening in the database. Note that there are no calls
to chat_message.chat_mention in Core and plugins so this
change should be safe.
Also note, that at the moment we use the chat_mentions db
table only to support notifications about mentions, but
we're going to start using it for other cases. This commit is
the first step in that direction.
Triggers a DiscourseEvent when a message is deleted, similar to
`:chat_message_created` and `:chat_message_edited`. This is not used
in this plugin, but can be used by other plugins to act when a message
is trashed.
Deleting a message with a mention doesn't clear the associated notification, confusing the mentioned user.
There are different chat notification types, but we only care about `chat_mentioned` since `chat_quoted` is associated with a post, and `chat_message` is only for push notifications.
Unfortunately, this change doesn't fix the chat bubble getting out of sync when a message gets deleted since we track unread/mentions count with an integer, making it a bit hard to manipulate. We can follow up later if we consider it necessary.

This new table will be used to automatically group replies
for messages into one place. In future additional functionality
will be built around the thread, like pinning messages, changing
the title, etc., the columns are just the main ones needed at first.
The columns are not prefixed with `chat_*` e.g. `chat_channel` since
this is redundant and just adds duplication everywhere, we want to
move away from this generally within chat.
Adds hidden `enable_experimental_chat_threaded_discussions`
setting which will control whether threads show in the UI,
alongside the `ChatChannel.threading_enabled` boolean column,
which does the same. The former is a global switch for this
feature, while the latter can be used to allow single channels
to show this new functionality if the site setting is true.
Neither setting impacts whether `ChatThread` records (which will
be added in a future PR) will be created, they will always be
made regardless.
This commit introduces the ability to edit the channel
slug from the About tab for the chat channel when the user
is admin. Similar to the create channel modal functionality
introduced in 641e94f, if
the slug is left empty then we autogenerate a slug based
on the channel name, and if the user just changes the slug
manually we use that instead.
We do not do any link remapping or anything else of the
sort, when the category slug is changed that does not happen
either.

Only allow maximum of `50_000` characters for chat drafts. A hidden `max_chat_draft_length` setting can control this limit. A migration is also provided to delete any abusive draft in the database.
The number of drafts loaded on current user has also been limited and ordered by most recent update.
Note that spec files moved are not directly related to the fix.

We've had the UploadReference table for some time now in core,
but it was added after ChatUpload was and chat was just never
moved over to this new system.
This commit changes all chat code dealing with uploads to create/
update/delete/query UploadReference records instead of ChatUpload
records for consistency. At a later date we will drop the ChatUpload
table, but for now keeping it for data backup.
The migration + post migration are the same, we need both in case
any chat uploads are added/removed during deploy.
Prior to this fix trashed channels would still prevent a channel with the same slug to be created. This commit generates a new slug on trash and frees the slug for future usage.
The format used for the slug is: `YYYYMMDD-HHMM-OLD_SLUG-deleted` truncated to the max length of a channel name.
This commit allows us to set the channel slug when creating new chat
channels. As well as this, it introduces a new `SlugsController` which can
generate a slug using `Slug.for` and a name string for input. We call this
after the user finishes typing the channel name (debounced) and fill in
the autogenerated slug in the background, and update the slug input
placeholder.
This autogenerated slug is used by default, but if the user writes anything
else in the input it will be used instead.
There was an issue with channel archiving, where at times the topic
creation could fail which left the archive in a bad state, as read-only
instead of archived. This commit does several things:
* Changes the ChatChannelArchiveService to validate the topic being
created first and if it is not valid report the topic creation errors
in the PM we send to the user
* Changes the UI message in the channel with the archive status to reflect
that topic creation failed
* Validate the new topic when starting the archive process from the UI,
and show the validation errors to the user straight away instead of
creating the archive record and starting the process
This also fixes another issue in the discourse_dev config which was
failing because YAML parsing does not enable all classes by default now,
which was making the seeding rake task for chat fail.
* FIX: Channel archive N1 when serializing current user
The `ChatChannelSerializer` serializes the archive for the
channel if it is present, however this was causing an N1 for
the current user serializer in the case of DM channels, which
were not doing `includes(:chat_channel_archive)` in the
`ChatChannelFetcher`.
DM channels cannot be archived, so we can just never try to serialize
the archive for DM channels in `ChatChannelSerializer`, which
removes the N1.
* DEV: Add N1 performance spec for latest.html preloading
We modify current user serializer in chat, so it's a good
idea to have some N1 performance specs to avoid regressions
here.
In certain cases, like when `SiteSetting.slug_generation_method`
is set to `none` with certain locales, the autogenerated chat
channel slugs will end up blank. This was causing errors in
unrelated jobs calling `update!` on the channel. Instead, we
should just copy Category behaviour, which does not error
if the autogenerated slug ends up blank. We already allow
for this with chat channel URLs, using `-` in place of the
missing slug.
This PR removes the limit added to max_users_notified_per_group_mention during #19034 and improve the performance when expanding mentions for large channel or groups by removing some N+1 queries and making the whole process async.
* Fully async chat message notifications
* Remove mention setting limit and get rid of N+1 queries
The client already has all the information about the current user so
there is no need for us to be serializing the current `User` object each
time per channel that is preloaded.
In production, profiling shows that this unneeded serializing
adds a roughly 5% overhead to a request.
Note this is a very large PR, and some of it could have been splited, but keeping it one chunk made it to merge conflicts and to revert if necessary. Actual new code logic is also not that much, as most of the changes are removing js tests, adding system specs or moving things around.
To make it possible this commit is doing the following changes:
- converting (and adding new) existing js acceptances tests into system tests. This change was necessary to ensure as little regressions as possible while changing paradigm
- moving away from store. Using glimmer and tracked properties requires to have class objects everywhere and as a result works well with models. However store/adapters are suffering from many bugs and limitations. As a workaround the `chat-api` and `chat-channels-manager` are an answer to this problem by encapsulating backend calls and frontend storage logic; while still using js models.
- dropping `appEvents` as much as possible. Using tracked properties and a better local storage of channel models, allows to be much more reactive and doesn’t require arbitrary manual updates everywhere in the app.
- while working on replacing store, the existing work of a chat api (backend) has been continued to support more cases.
- removing code from the `chat` service to separate concerns, `chat-subscriptions-manager` and `chat-channels-manager`, being the largest examples of where the code has been rewritten/moved.
Future wok:
- improve behavior when closing/deleting a channel, it's already slightly buggy on live, it's rare enough that it's not a big issue, but should be improved
- improve page objects used in chat
- move more endpoints to the API
- finish temporarily skipped tests
- extract more code from the `chat` service
- use glimmer for `chat-messages`
- separate concerns in `chat-live-pane`
- eventually add js tests for `chat-api`, `chat-channels-manager` and `chat-subscriptions-manager`, they are indirectly heavy tested through system tests but it would be nice to at least test the public API
<!-- NOTE: All pull requests should have tests (rspec in Ruby, qunit in JavaScript). If your code does not include test coverage, please include an explanation of why it was omitted. -->
Prior to this change, each request executed 2 Redis calls per chat channel
that was loaded. The number of Redis calls quickly adds up once a user
is following multiple channels.
This commit adds an index for the query which the chat plugin executes
multiple times when preloading user data in `Chat::ChatChannelFetcher.unread_counts`.
Sample query plan from a query I grabbed from one of our production
instance.

In both ChatMessage#rebake! and in ChatMessageProcessor
when we were calling ChatMessage.cook we were missing the
user_id to cook with, which causes missed hashtag cooks
because of missing permissions.
Previously, restricted category chat channel was available for all groups - even `readonly`. From now on, only user who belong to group with `create_post` or `full` permissions can access that chat channel.
There is no need to duplicate check chat messages when they are being
edited but not having their message text changed. This was leading to
a validation error when adding/removing an upload but not changing the
message text.
Instead of passing `user` to `guardian.can_chat?`, we
can just use the inner `@user` that is part of the guardian
instance already to determine whether that user can chat,
since this is how it works for all other usages of guardian
even within chat.
* FEATURE: Enforce mention limits for chat messages
The first part of these changes adds a new setting called `max_mentions_per_chat_message`, which skips notifications when the message contains too many mentions. It also respects the `max_users_notified_per_group_mention` setting
and skips notifications if expanding a group mention would exceed it.
We also include a new component to display JIT warning for these limits to the user while composing a message.
* Simplify ignoring/muting filter in chat_notifier
* Post-send warnings for unsent warnings
* Improve pluralization
* Address review feedback
* Fix test
* Address second feedback round
* Third round of feedback

This commit adds the messages_count column for ChatChannel messages,
which is the number of not-deleted messages in the channel.
This is not updated every time a message is created or deleted in a
channel, so it should not be displayed in the UI.
It is updated eventually via Jobs::ChatPeriodicalUpdates, which
will have additional functions in future after being introduced
here.
Also update these counts for existing channels in a post migration.
The settings tab of each category channel should now present the option to allow or disallow channel wide mentions: @here and @all.
When disallowed, using these mentions in the channel should have no effect.
There must have been a small loophole that allowed
setting the channel slug in the DB which has led to
conflicts in some cases.
This commit fixes the conflicting chat channel
slugs and then changes the channel slug index
to a unique one in the DB.
This commit adds variousMessageBus.last_ids to serializer payloads
for chat channels and the chat view (for chat live pane) so
we can use those IDs when subscribing to MessageBus channels
from chat.
This allows us to ensure that any messages created between the
server being hit and the UI loaded and subscribing end up being
delivered to the client, rather than just silently dropped.
This commit also fixes an issue where we were subscribing to
the new-messages and new-mentions MessageBus channels multiple
times when following/unfollowing a channel multiple times.
This commit introduce a new API for registering callbacks, which we'll execute when a user gets destroyed, and the `delete_posts` opt is true. The chat plugin registers one callback and queues a job to destroy every message from that user in batches.
* FIX: Unsilence users on chat message flag disagree.
We have an auto silence rule in place for chat message flags, so we need to unsilence users if the flag gets rejected.
Additionally, it also fixes the `disagree_and_restore` action, which wasn't recovering a deleted message.
* Update plugins/chat/spec/models/reviewable_chat_message_spec.rb

Only allow maximum of 6000 characters for chat messages when they
are created or edited. A hidden setting can control this limit,
6000 is the default.
There is also a migration here to truncate any existing messages to
6000 characters if the message is already over that and if the
chat_messages table exists. We also set cooked_version to NULL
for those messages so we can identify them for rebake.
