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 will ensure we enter and subscribe to presence channels on start and will use the correct "change" events from presence channel to update state.
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.

UI is not modified much besides removing the border-bottom, and using only message body.
However instead of having a fix template, this is all automatically generated and random, resulting in a more natural experience.
Only the header's height and 15px spacing are removed from the height of the viewport.
Previously it was limited to 90vh and there was also a useless property on a child node limiting it to 85vh. We now use only one property.
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 change was made to prevent composer input to be reset randomly during tests but this is causing more issues for now: most notably composer state not being reset when changing channel. This will need a better solution.
* DEV: Rnemae channel path to just c
Also swap the channel id and channel slug params to be consistent with core.
* linting
* channel_path
* Drop slugify helper and channel route without slug
* Request slug and route models through the channel model if possible
* DEV: Pass messageId as a dynamic segment instead of a query param
* Ensure change is backwards-compatible
* drop query param from oneboxes
* Correctly extract channelId from routes
* Better route organization using siblings for regular and near-message
* Ensures sessions are unique even when using parallelism
* prevents didReceiveAttrs to clear input mid test
* we disable animations in capybara so sometimes the message was barely showing
* adds wait
* ensures finished loading
* is it causing more harm than good?
* this check is slowing things for no reason
* actually target the button
* more resilient select chat message
* apply similar fix to bookmark
* fix

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.
`last_message_sent_at` could be equal and as a result the order would be random causing random spec failures in plugins/chat/spec/mailers/user_notifications_spec.rb:182
Using a shared channel with per-message permissions means that every client is updated with the channel's 'last_id', even if there are no messages available to them. Per-user channel names avoid this problem - the last_id will only be incremented when there is a message for the given user.
* FIX: correct various mistakes in chat-notification-manager
- The code was still handling global chat through its own variable instead of relying on `ChatStateManager`
- There was a typo were the code was using `this` instead of `opts`
Note notifications are a future big work of this year and this should be heavily reworked and tested.
* linting
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.
When expanding the "Advanced mode" of the date modal, the Timezones
picker was at the bottom of the modal, and expanding it would often
overflow the viewport. This PR moves the elment higher up, therefore
avoiding the overflow.
There's a small width change as well, for better consistency.
* DEV: Rnemae channel path to just c
Also swap the channel id and channel slug params to be consistent with core.
* linting
* channel_path
* params in wrong order
* Drop slugify helper and channel route without slug
* Request slug and route models through the channel model if possible
* Add client side redirection for backwards-compatibility
