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.
[1/4] [model] 'user' ❌
[2/4] [policy] 'can_see_user'
[3/4] [contract] 'default'
[4/4] [step] 'update_age'

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.
Whenever we create a chat message that is `in_reply_to` another
message, we want to lazily populate the thread record for the
message chain.
If there is no thread yet for the root message in the reply chain,
we create a new thread with the appropriate details, and use that
thread ID for every message in the chain that does not yet have
a thread ID.
* Root message (ID 1) - no thread ID
* Message (ID 2, in_reply_to 1) - no thread ID
* When I as a user create a message in reply to ID 2, we create a thread and apply it to ID 1, ID 2, and the new message
If there is a thread for the root message in the reply chain, we
do not create one, and use the thread ID for the newly created chat
message.
* Root message (ID 1) - thread ID 700
* Message (ID 2, in_reply_to 1) - thread ID 700
* When I as a user create a message in reply to ID 2, we use the existing thread ID 700 for the new message
We also support passing in the `thread_id` to `ChatMessageCreator`,
which will be used when replying to a message that is already part of
a thread, and we validate whether that `thread_id` is okay in the context
of the channel and also the reply chain.
This work is always done, regardless of channel `thread_enabled` settings
or the `enable_experimental_chat_threaded_discussions` site setting.
This commit does not include a large data migration to backfill threads for
all existing reply chains, its unnecessary to do this so early in the project,
we can do this later if necessary.
This commit also includes thread considerations in the `MessageMover` class:
* If the original message and N other messages of a thread is moved,
the remaining messages in the thread have a new thread created in
the old channel and are moved to it.
* The reply chain is not preserved for moved messages, so new threads are
not created in the destination channel.
In addition to this, I added a fix to also clear the `in_reply_to_id` of messages
in the old channel which are moved out of that channel for data cleanliness.

Public channels were previously sorted by name, however, channels with a leading emoji in the name would always appear first in the list. By using slug we avoid this issue.
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.
First follow-up to the feature introduced in #19034. We don't want to pollute main components like `chat-live-pane`, so we'll use a service to track and manage the state needed to display before-send warnings while composing a chat message.
We also move from acceptance tests to system specs.
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 commit implements a requested feature: resizing the chat drawer.
The user can now adjust the drawer size to their liking, and the new size will be stored in localstorage so that it persists across refreshes. In addition to this feature, a bug was fixed where the --composer-right margin was not being correctly computed. This bug could have resulted in incorrectly positioned drawer when the composer was expanded.
Note that it includes support for RTL.
* FIX: Emoji autocomplete “more” button not working
* Rely on setting an intial value on the filter input
This commit removes custom logic applied on initial filter and instead gives a param to use as value for the input, automatically triggering the existing filtering handler.
Other notes:
- Slightly changes the API to be able to set a filter and open the composer in one go
- Adds a very simple service spec
- Adds a system spec to fully validate the behavior

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.
We refer to the channel name rather than title elsewhere
(including the new channel modal), so we should be consistent.
Title is an internal abstraction, since DM channels cannot have
names (currently).
Also change the name field on channel edit to a input type="text"
rather than a textarea, since we don't want a huge input here.
Added in c2013865d7,
this migration was supposed to only turn off the hashtag
setting for existing sites (since that was the old default)
but its doing it for new ones too because we run all migrations
on new sites.
Instead, we should only run this if the first migration was
only just created, meaning its a new site.
If the enable_experimental_hashtag_autocomplete setting is
enabled, then we should autolink hashtag references to the
archived channels (e.g. #blah::channel) for a nicer UX, and
just show the channel name if not (since doing #channelName
can lead to weird inconsistent results).
The spec was flaky because it was dependent on order,
when usernames got high enough sequence numbers in them
we would get this error:
> expected to find text "bruce99, bruce100" in "bruce100, bruce99"
Also move selectors into page object and use them in the
spec 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.
The problem here was that if your input has an Enter
listener (such as the chat message input) and the
`fill_in(with: str)` string has a `\n` at the end, this
is treated as an Enter keypress, so this `fill_in` was
submitting the chat message.
This commit fixes an issue where the chat message bookmarks
did not respect the user's `bookmark_auto_delete_preference`
which they select in their user preference page.
Also, it changes the default for that value to "keep bookmark and clear reminder"
rather than "never", which ends up leaving a lot of expired bookmark
reminders around which are a pain to clean up.
This commit is a series of fixes to improve stability of system tests following the use of threadsafe:
* Jobs.run_immediately in before block was causing issues
* During test a js error could be caused by an undefined this.details in chat-live-pane
* Apply the chat composer click trick everywhere when sending a message, it ensures we are not hiding anything with autocomplete
* There was another case not using send_message yet
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
It should fix flakeys we have due to using_session. This commit is also fixing tests which were failing constantly with treadsafe enabled.
A test has also bene skipped as the issue couldn't be found so far.

- improves UI by displaying channel status on it's own line
- ensures channel status is correctly updated right after the request on frontend
- adds status on info page
Recent changes surfaced the various issues with this codepath:
- we were not correctly reseting `messageLookup` leading to us trying to scroll to a non existing message in the view
- we were calling markAsRead which would scroll to the bottom, even if we had a target message
- we were not debouncing fetchMessages, which could cause multiple reload of the messages when loading it with a targetMessageId: first fetch from last read and then immediately fetch from targetMessageId
- other naming inconsistencies
- not handling drawer
This commit also adds tests for classic scenarios related to this use case.
