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.
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.
Followup to bd5c5c4b5f,
this commit hooks up the bulk delete events for chat
messages inside the thread panel, by fanning out the
deleted message IDs based on whether they belong to
a thread or not.
Also adds a system spec to cover this case, as previously
the bulk delete event would have been broken with an incorrect
`typ` rather than `type` hash key.
This error was only happening on mobile, note we also already have a (mobile) test (plugins/chat/spec/system/transcript_spec.rb:184) for this which was passing as it's only happening at a specific speed. I don't want to complicate the test too much for this case, will reconsider if it regresses again.
This regression happened in bd5c5c4b5f and is due to `message_bus_targets = calculate_publish_targets(chat_channel, chat_message)` expecting a `chat_channel` which was only defined after.
Example exception in logs:
```

This commit also:
- adds a spec to ensure oneboxing is not regressing anymore
- increment the version on message processed to ensure callbacks are correctly ran
Note we should also have more tests in `Chat::Publisher`, this will be done when we move it to a proper service.

This codepath was responsible to scroll to the first emoji of a section, however `scrollIntoView` was not super reliable and was also causing the whole page to scroll with drawer. This is also simply not necessary code as native focus behavior will scroll to the element.
This commit introduces a ChatChannelPaneSubscriptionsManager
and a ChatChannelThreadPaneSubscriptionsManager that inherits
from the first service that handle MessageBus subscriptions
for the main channel and the thread panel respectively.
This necessitated a change to Chat::Publisher to be able to
send MessageBus messages to multiple channels based on whether
a message was an OM for a thread, a thread reply, or a regular
channel message.
An initial change to update the thread indicator with new replies
has been done too, but that will be improved in future as we have
more data to update on the indicators.
Still remaining is to fully move over the handleSentMessage
functionality which includes scrolling and new message indicator
things.

- Back button in drawer will bring you back to channel
- Larger font for thread indicator
- Prevents screen flashing due to clearing messages when they were already loaded
- Fixes a bug where did-update params were inverted causing an error when expanding/collapsing drawer
This feature will allow sites to define which emoji are not allowed. Emoji in this list should be excluded from the set we show in the core emoji picker used in the composer for posts when emoji are enabled. And they should not be allowed to be chosen to be added to messages or as reactions in chat.
This feature prevents denied emoji from appearing in the following scenarios:
- topic title and page title
- private messages (topic title and body)
- inserting emojis into a chat
- reacting to chat messages
- using the emoji picker (composer, user status etc)
- using search within emoji picker
It also takes into account the various ways that emojis can be accessed, such as:
- emoji autocomplete suggestions
- emoji favourites (auto populates when adding to emoji deny list for example)
- emoji inline translations
- emoji skintones (ie. for certain hand gestures)
This commit introduces a new thread indicator for channels with `threading_enabled`
set to true and the `enable_exp` site setting set to true. In addition, in the main channel
stream we now hide all messages that are linked to threads except for the original message,
disabling the concept of an "echo mode" for now, we may revisit this in future. We also
remove the jigsaw puzzle "Open Thread" button for message actions, since the thread
indicator can just be used instead.
This also stops the `Chat::Publisher` from sending any messages related to chat
messages that are linked to a thread, unless that chat message is the OM of the
thread. A subsequent PR will link up all MessageBus events within the thread panel,
and for the message indicators.
Another subsequent PR will add the excerpt of the latest message in each thread,
as well as the avatars of the users messaging in the thread.

- rounded active style for messages
- better active state on chat message actions rows
- ensures long press on a message is not selecting text
- slightly improved messages actions animation and background fading
- ensures chat emoji picker is not cutoff on right side
- removes old legacy code related to hovered message
Followup to c1dc6a2db4,
this commit just missed removing one of the @computed
decorators which was causing multiple active channels
to show in the sidebar. Fix the issue and introduce a
system spec to catch this.
- clicking empty area on the header will toggle collapse/expand it
- applies a background on hover of the channel title
- active state for small buttons
- the back button now has the correct icon color when hovered
- adds missing focus state for heade buttons icons
When hovering the chat message actions we are technically not hovering the message anymore, which was removing the background and is slightly unexpected. This commit ensures we keep this background until closing the message actions.
This PR primarily fixes this case:
- USER A message
- USER B message
- USER B reply to USER A message <-- not showing user info when it should
Moreover, this commit also improves the spec to correctly test more cases.
This commit is a major overhaul of how chat message actions work, to make it so they are reusable between the main chat channel and the chat thread panel, as well as many improvements and fixes for the thread panel.
There are now several new classes and concepts:
* ChatMessageInteractor - This is initialized from the ChatMessage, ChatMessageActionsDesktop, and ChatMessageActionsMobile components. This handles permissions about what actions can be done for each
message based on the context (thread or channel), handles the actions themselves (e.g. copyLink, delete, edit),
and interacts with the pane of the current context to modify the UI
* ChatChannelThreadPane and ChatChannelPane services - This represents the UI context which contains the
messages, and are mostly used for state management for things like message selection.
* ChatChannelThreadComposer and ChatChannelComposer - This handles interaction between the pane, the
message actions, and the composer, dealing with reply and edit message state.
* Scrolling logic for the messages has now been moved to a helper so it can be shared between the main channel pane and the thread pane
* Various improvements with the emoji picker on both mobile and desktop. The DOM node of each component is now located outside of the message which prevents a large range of issues.
The thread panel now also works in the chat drawer, and the thread messages have less
actions than the main panel, since some do not make sense there (e.g. moving messages to
a different channel). The thread panel title, excerpt, and message sender have also been removed
for now to save space.
This gives us a solid base to keep expanding on and fixing up threads. Subsequent PRs will
make the thread MessageBus subscriptions work and disable echo mode
for the initial release of threads.

This commit adds a system to generate CSS variables and classes for categories
and hashtags, which will be used in an effort to remove baked icons for hashtags
and add color to those icons.
This is in two parts. First I added an initializer generate a category color CSS
variable style tag in the head tag that looks like this:
```css
:root {
--category-1-color: #0088CC;
--category-2-color: #808281;
--category-3-color: #E45735;
--category-4-color: #A461EF;
--category-5-color: #ee56c9;
--category-6-color: #da28c2;
--category-7-color: #ab8b0a;
--category-8-color: #45da37;
...
}
```
The number is the category ID. This only generates CSS variables for categories
the user can access based on `site.categories`. If you need the parent color variable
you can just use the `category.parentCategory.id` to get it.
Then, I added an initializer to generate a hashtag CSS style tag using these variables.
Only the category and channel hashtags need this, the category one generates the
background-gradient needed for the swatch, and the channel just generates a color
for the icon. This is done in an extendable way using the new `api.registerHashtagType`
JS plugin API:
```css
hashtag-color--category-1 {
background: linear-gradient(90deg, var(--category-1-color) 50%, var(--category-1-color) 50%);
}
hashtag-color--category-2 {
background: linear-gradient(90deg, var(--category-2-color) 50%, var(--category-2-color) 50%);
}
hashtag-color--category-5 {
background: linear-gradient(90deg, var(--category-5-color) 50%, var(--category-4-color) 50%);
}
...
.hashtag-color--channel-4 {
color: var(--category-12-color);
}
.hashtag-color--channel-92 {
color: var(--category-24-color);
}
```
Note if a category has a parent, its color is used in the gradient correctly. The numbers
here are again IDs (e.g. channel ID, category ID) and the channel’s chatable ID is used
to find the category color variable.
When a chat message is trashed and the message is used
for someone's UserChatChannelMembership#last_read_message_id,
the user would end up with some read state issues until
someone posted a new message in the channel, since we didn't
clear it like we did on bulk message delete.
This commit fixes the issue, and also takes the opportunity
to start a MessagesController in the API namespace, and move
the trash message functionality into the new service format.
- Raises the scroll distance to 250px instead of 100px to show the arrow down button
- Always have a margin on drawer when showing channel list, removes this margin when the scrollbar is apparent
- Makes all scrollbar used in chat look the same through the chat-scrollbar mixin
- Ensures hover state is not persistent on channel row in mobile
- Makes the channel row full width on mobile
This commit introduces a Chat::Publisher and MessageBus endpoint
that allows for updating a user's channel tracking state in bulk for
multiple channels, rather than having to do it for one channel
at a time.
This also required an improvement to ChannelUnreadsQuery -- now
multiple channel IDs can be passed to this to get the unread counts
and mention counts for those channels for a user, also increasing
efficiency rather than having to do a query for every individual
channel.
Followup to #20802
Instead of just marking the state read in JS for each channel
after the AJAX call, we can instead just rely on the MessageBus
user-tracking-state chat channel, and publish the state to all
the channels affected in MarkAllUserChannelsRead. This will make
it so the blue dots for the channels are cleared across all tabs.
This manual set was happening only after the request so was not much faster than just waiting on message bus update. It's not by itself changing any behavior or fixing any bug but it makes reasoning about the whole state easier as it happens in only one central place.
Followup to a0381157e9, we just
need to make sure we set currentUserMembership.last_read_message_id
to the last_read_message_id from the updated memberships after marking
all channels read, otherwise we do not scroll to the bottom and still
show the "last visit" separators in channels that have been
marked read.
This commit adds a keyboard shortcut (Shift+ESC) for chat which marks all
of the chat channels that the user is currently a following member of as read,
updating their `last_read_message_id`. This is done via a new service.
It also includes some refactors and controller changes:
* The old mark message read route from `ChatController` is now supplanted
by the `Chat::Api::ReadsController#update` route.
* The new controller can handle either marking a single or all messages read,
and uses the correct service based on the route and params.
* The `UpdateUserLastRead` service is now used (it wasn't before), and has been slightly
updated to just use the guardian user ID.
There are many situations that may cause users to lose permission to
send messages in a chat channel. Until now we have relied on security
checks in `Chat::ChatChannelFetcher` to remove channels which the
user may have a `UserChatChannelMembership` record for but which
they do not have access to.
This commit takes a more proactive approach. Now any of these following
`DiscourseEvent` triggers may cause `UserChatChannelMembership`
records to be deleted:
* `category_updated` - Permissions of the category changed
(i.e. CategoryGroup records changed)
* `user_removed_from_group` - Means the user may not be able to access the
channel based on `GroupUser` or also `chat_allowed_groups`
* `site_setting_changed` - The `chat_allowed_groups` was updated, some
users may no longer be in groups that can access chat.
* `group_destroyed` - Means the user may not be able to access the
channel based on `GroupUser` or also `chat_allowed_groups`
All of these are handled in a distinct service run in a background
job. Users removed are logged via `StaffActionLog` and then we
publish messages on a per-channel basis to users who had their
memberships deleted.
When the user has a channel they are kicked from open, we show
a dialog saying "You no longer have access to this channel".
When they click OK we redirect them either:
* To their first other public channel, if they have any followed
* The chat browse page if they don't
This is to save on tons of requests from kicked out users getting messages
from other channels.
When the user does not have the kicked channel open, we can just
silently yoink it out of their sidebar and turn off subscriptions.
Prior to this fix, we wouldn't display reactions done on different tabs. So, if user A was reacting on tab 1, tab 2 wouldn't display this reaction.
Since few weeks ago we now have the guarantee to have uniq reactions on a message which should prevent any duplicate.
This commit also removes various skipped tests related to reactions and makes `sign_in` explicit at the beginning of each test.
<!-- 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. -->
This commit takes advantage of the `ResizeObserver` to know when dates should be re-computed, it works like this:
```
scrollable-div
-- child-enclosing-div with resize observer
---- message 1
---- message 2
---- message x
```
It also switches to bottom/height for date separators sizing, instead of bottom/top, it prevents a bug where setting the top of the first item (at the top) would cause scrollbar to move to top.
<!-- 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. -->
This commit does a couple of things:
* Adds the ability to load messages in the chat thread panel when it is open. This just loads the most recent N messages, same as a channel, and does nothing more, no scrolling or anything like that.
* Displays the messages in an extremely simple unordered list with no additional features.
* Allows posting new messages to the thread, and echoes them into the main channel, but does not respond to any sort of MessageBus events.
I've moved messages/clearMessages/addMessages/findMessage code out of the `ChatChannel` model
and into a new `ChatMessagesManager` class, which is instantiated in both the `ChatChannel` model
and the `ChatThread` model. This allows both to manage messages in the same way via the
`TrackedArray` pattern.
This is all hidden behind experimental flags, there is no way to make this not completely broken
in a single commit. Much more work and refactoring needs to be done first.

This behavior is hard to test as it's mostly fixing a race condition: User A sends a message at the same time than User B, which as a result doesn't cause a scroll for the second message and we don't update last read unless we do a small up and down scroll.
`updateLastRead` is debounced so it has no direct consequences to call it slightly more often than what should ideally be needed.
Prior to this fix, the upload was removed from DOM when collapsed and not decorated again on expand, which was causing lightbox to not get reapplied. The fix is reverting to previous state where content was not removed from DOM.
This commit main goal was to comply with Zeitwerk and properly rely on autoloading. To achieve this, most resources have been namespaced under the `Chat` module.
- Given all models are now namespaced with `Chat::` and would change the stored types in DB when using polymorphism or STI (single table inheritance), this commit uses various Rails methods to ensure proper class is loaded and the stored name in DB is unchanged, eg: `Chat::Message` model will be stored as `"ChatMessage"`, and `"ChatMessage"` will correctly load `Chat::Message` model.
- Jobs are now using constants only, eg: `Jobs::Chat::Foo` and should only be enqueued this way
Notes:
- This commit also used this opportunity to limit the number of registered css files in plugin.rb
- `discourse_dev` support has been removed within this commit and will be reintroduced later
<!-- 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. -->
Non-markdown tags weren't being escaped in chat excerpts. This could be
triggered by editing a chat message containing a tag (self XSS), or by
replying to a chat message with a tag (XSS).

Usage:
```javascript
api.addChatDrawerStateCallback(({ isDrawerActive, isDrawerExpanded }) => {
// do something
});
```
Note this commit also uses this new API to add a css class (chat-drawer-active) on the body when the drawer is active.
This fix uses direct `scrollTop` manipulation instead of `scrollIntoView` when we are certain we actually want the bottom of the screen. This avoids a range of issues especially in safari but also chrome where the scroll position was not correct at the end of `scrollIntoView`, especially due to images.
- Will consider a message read only one the bottom of the message has been read
- Will allow to mark a message bigger than the view port as read
- Code should be more performant as the scroll is doing less (albeit more often)
- Gives us a very precise scroll state. Problem with throttling scroll is that you could end up never getting the even where scrollTop is at 0, opening a whole range of edge cases to handle
1. Restore the left margin on both (which reflects the right margin of the scroll bar space)
2. Fix the center alignment of scroll-to-bottom icon
3. Fix the spacing of the `-` character between a date label and "last visit" label
4. Fix the incorrect display the border on date label when at the bottom of viewport
When we introduced `existingUploads` as an arg to the
ChatComposerUploads component, we also introduced a bug where
if multiple uploads were being done at once, and the draft
was saved, then because of didReceiveAttrs we would cancel
the currently uploading files because the draft uploads became
the existingUploads.
To work around this, since we do want to keep this on didReceiveAttrs
for cases when the user opens a draft or edits another message,
the easiest thing to do is to just not save uploads into the chat
draft if there are still uploads in progress. That way only when
all uploads are complete do we make them a part of the draft.
There is a small risk that the user could do something to lose
their uploads in the draft, but it's a better gamble to have
that happen rather than in progress uploads to be cancelled
while the user is waiting for them to be done because of the
draft.
Also changes the uploads system spec back to the old way of
attaching multiple files since that is why it was failing.
- group writes when computing separators positions
- shows skeleton only on initial load
- forces date separator to be pinned when first message to prevent a pinned - not pinned - pinned sequence when loading more in past
- relies on `message.visible` property instead of checking `isElementInViewport`
- attempts to load next/prev messages earlier
- do not scroll to on fetch more
- hides `last visit` text while pinned
Note this test my prove to be flakey, so I might have to remove it or find a different solution. It's extremely complicated to test for something which shouldn't appear in a period of time and is not a present at T=0
This was possible due to specific events which are hard to represent in a test. The provided test is as close as possible to what was happening in production: a message bus event was played on a channel which has just loaded its state with the existing reaction.
On require login sites, the `site` is not setup and as a result `hashtag_configurations` was blank and causing an error when attempting to access `["chat-composer"]` on it.
This PR is introducing glimmer usage in the chat-live-pane, for components but also for models. RestModel usage has been dropped in favor of native classes.

better unread management, marking a channel as unread will correctly mark the correct message and not mark the whole channel as read. Tracking state will also now correctly return unread count and unread mentions.
adds an animation on bottom arrow
better scrolling behavior, we should now always correctly keep the scroll position while loading more
reactions are now more reactive, and will update their tooltip without needed to close/reopen it
skeleton has been improved with placeholder images and reactions
when making a reaction on the desktop message actions, the menu won't move anymore
simplify logic and stop maintaining a list of unloaded messages

This commit allows the user to set their preference vis-a-vis
the chat icon in the header of the page. There are three options:
- All New (default) - This maintains the existing behaviour where
all new messages in the channel show a blue dot on the icon
- Direct Messages and Mentions - Only show the green dot on the
icon when you are directly messaged or mentioned, the blue dot
is never shown
- Never - Never show any dot on the chat icon, for those who
want tractor-beam-laser-focus
Fixes issue introduced in 7ef482a292
where the correct warning message was not shown when enabling auto-join
for public categories when creating a channel. Adds more system specs
as well to avoid regressions.
**This PR creates a new core reusable component wraps a character counter around any input.**
The component accepts the arguments: `max` (the maximum character limit), `value` (the value of text to be monitored).
It can be used for example, like so:
```hbs
<CharCounter @max="50" @value={{this.charCounterContent}}>
<textarea
placeholder={{i18n "styleguide.sections.char_counter.placeholder"}}
{{on "input" (action (mut this.charCounterContent) value="target.value")}}
class="styleguide--char-counter"></textarea>
</CharCounter>
```
**This PR also:**
1. Applies this component to the chat plugins edit channel's *Edit Description** modal, thereby replacing the simple text area which provided no visual indication when text exceeded the max allowed characters.
2. Adds an example to the `/styleguide` route

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.
This commit changes the ChatThreadsManager into a native
class instead of an ember service, and initializes it
for every ChatChannel model. This way each channel has its
own thread manager and cache that we can load/unload as
needed, and we also move activeThread to the channel since
it makes more sense to keep it there, not inside the chat service.
The pattern of calling setOwner with the passed in owner
from ChatChannel is adapted from the latest ember docs,
and is needed to avoid the error below when calling services
from the native class:
> Attempting to lookup an injected property on an object without a container, ensure that the object was instantiated via a container
It works well _only_ if we use our own getOwner wrapper
from addon/lib/get-owner, which is for backwards compat.

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

* 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.
* 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

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.

This change has two goals:
- Fixes an issue when the user had zoomed the viewport and the popper would position on the opposite side
- Makes msg actions arguably more pleasant to the eye by preventing it to be right aligned with the message container
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.
Note this commit also slightly changes internal API: channel instead of getChannel and updateCurrentUserChannelNotificationsSettings instead of updateCurrentUserChatChannelNotificationsSettings.
Also destroyChannel takes a second param which is the name confirmation instead of an optional object containing this confirmation. This is to enforce the fact that it's required.
In the future a top level jsdoc config file could be used instead of the hack tempfile, but while it's only an experiment for chat, it's probably good enough.
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.
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.
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
- 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.
We are all in on system specs, so this commit moves all the chat quoting acceptance tests (some of which have been skipped for a while) into system specs.
Following the removal of user in current_user_membership we were now doing: `User.create(null)`.
I don't think it has any impact but this is just wasteful and could lead to issues if used.
- chat-message is not using chat-api yet and the `jsonMode` shouldn't have been added
- correctly error on `getChannel` not found
- adds/correct relevant system tests
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

1. "What Goes Up Must Come Down" – if you subscribe to message bus, make sure you also unsubscribe
2. When you unsubscribe - remove only your subscription, not **all** subscriptions on given channel
Attempt #2. The first attempt tried to extend a core `@bound` method in new-user-narrative plugin which did not work. I reworked that plugin in the meantime. This new PR also cleans up message bus subscriptions in now core-merged chat plugin.
We must set `treatAsTextarea` to true when using autocomplete
in the chat composer, since it is at the bottom of the screen
we always want to show it above the composer. This fixes the
issue where the hashtag autocomplete results went behind the
keyboard on mobile (which was not happening for mentions).
This new site setting replaces the
`enable_experimental_sidebar_hamburger` and `enable_sidebar` site
settings as the sidebar feature exits the experimental phase.
Note that we're replacing this without depreciation since the previous
site setting was considered experimental.
Internal Ref: /t/86563
* 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

User options were serialized at the root level of CurrentUserSerializer,
but UserSerializer has a user_option field. This inconsistency caused
issues in the past because user_option fields had to be duplicated on
the frontend.
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.
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.
`ember-cached-decorator-polyfill` uses a Babel transformation to apply this polyfill in core. Adding that Babel transformation to themes and plugins will be complex, so we use this to patch it at runtime. This can be removed once `@glimmer/tracking` is updated to a version
with native `@cached` support.
`reviewable.chat_channel` is a plain javascript object from the server's JSON response. We need to turn it into a true `ChatChannel` object before passing to `<ChatChannelTitle>`
This commit also converts `<ReviewableChatMessage>` to a Glimmer component
- Multiple style improvements
- adds last sent message date to the view

The drawer is registering events which are expecting the drawer to always be present which was not the case anymore. A previous refactor also changed this component to be tagless.
Refines the behavior of clicking the chat icon in mobile and when in drawer mode as follows: If chat is open, clicking the icon takes you to the index.
- better handling of drawer state using chat state manager
- removes various float and topic occurrences to use drawer
- ensures user can chat before doing a lot of chat setup
- fixes a bug which was creating presence errors in tests
- removes dead code
7e39a21de1
broke the explanation of the check box on `create-channel` view.
Actions:
- uses core yes_value/no_value
- re-add the correct translation for `enable_auto_join_users`
- removes `disable_auto_join_users` which is not used anymore
- prevents menu to hide underlying text
- prevents `chat-message-actions` to close when hovering dropdown of 3
dots button as mouse would hover an other message due to the small space
between `chat-message-actions` menu and the dropdown of the 3 dots
button

This commit fleshes out and adds functionality for the new `#hashtag` search and
lookup system, still hidden behind the `enable_experimental_hashtag_autocomplete`
feature flag.
**Serverside**
We have two plugin API registration methods that are used to define data sources
(`register_hashtag_data_source`) and hashtag result type priorities depending on
the context (`register_hashtag_type_in_context`). Reading the comments in plugin.rb
should make it clear what these are doing. Reading the `HashtagAutocompleteService`
in full will likely help a lot as well.
Each data source is responsible for providing its own **lookup** and **search**
method that returns hashtag results based on the arguments provided. For example,
the category hashtag data source has to take into account parent categories and
how they relate, and each data source has to define their own icon to use for the
hashtag, and so on.
The `Site` serializer has two new attributes that source data from `HashtagAutocompleteService`.
There is `hashtag_icons` that is just a simple array of all the different icons that
can be used for allowlisting in our markdown pipeline, and there is `hashtag_context_configurations`
that is used to store the type priority orders for each registered context.
When sending emails, we cannot render the SVG icons for hashtags, so
we need to change the HTML hashtags to the normal `#hashtag` text.
**Markdown**
The `hashtag-autocomplete.js` file is where I have added the new `hashtag-autocomplete`
markdown rule, and like all of our rules this is used to cook the raw text on both the clientside
and on the serverside using MiniRacer. Only on the server side do we actually reach out to
the database with the `hashtagLookup` function, on the clientside we just render a plainer
version of the hashtag HTML. Only in the composer preview do we do further lookups based
on this.
This rule is the first one (that I can find) that uses the `currentUser` based on a passed
in `user_id` for guardian checks in markdown rendering code. This is the `last_editor_id`
for both the post and chat message. In some cases we need to cook without a user present,
so the `Discourse.system_user` is used in this case.
**Chat Channels**
This also contains the changes required for chat so that chat channels can be used
as a data source for hashtag searches and lookups. This data source will only be
used when `enable_experimental_hashtag_autocomplete` is `true`, so we don't have
to worry about channel results suddenly turning up.
------
**Known Rough Edges**
- Onebox excerpts will not render the icon svg/use tags, I plan to address that in a follow up PR
- Selecting a hashtag + pressing the Quote button will result in weird behaviour, I plan to address that in a follow up PR
- Mixed hashtag contexts for hashtags without a type suffix will not work correctly, e.g. #ux which is both a category and a channel slug will resolve to a category when used inside a post or within a [chat] transcript in that post. Users can get around this manually by adding the correct suffix, for example ::channel. We may get to this at some point in future
- Icons will not show for the hashtags in emails since SVG support is so terrible in email (this is not likely to be resolved, but still noting for posterity)
- Additional refinements and review fixes wil
Previously `this.chatService.appEvents.on(
"chat:user-tracking-state-changed"...)` was registered on constructor and disabled on `willDestroy`. Constructor is evaluated only once, so when the section was collapsed and collapsed then the events were not observed anymore.
didInsert allows evaluating code each time a component is rendered.
This implementation attempts to be more resilient to background tab.
Notes:
- adds support for immediate arg in @debounce decorators
- fixes a bug in discourseDebounce which was not supporting immediate arg in tests
- chat-audio-manager has no tests as audio requires real user interaction and is hard to test reliably
- Note this is also tweaking the UI a little bit as we are now using links/buttons in the header as needed
- It disables the find ideal channel in drawer mode, if loading `/chat` in drawer mode it will either reopen at the last position or just stay on index
- allows to scroll while hovering the menu
- correctly changes message background color while hovering menu
- prevents a bug where it would sometimes close the menu while moving from menu to the 3 dots expanded dropdown. This was caused by the gap between header/body of the 3 dots dropdown, which would sometimes allow to create a mouseover event on a possible different underlying message
- removes recent/favorite reactions on drawer mode
- grayscale reactions until hover
- boxshadow on msgactions container
- removes useless code
Toggling channel settings shows a status message when saved. This status message is not accessible to screen readers. This commit ensures that the status message is made accessible.
This commit automatically ensures that category channels
have slugs when they are created or updated based on the
channel name, category name, or existing slug. The behaviour
has been copied from the Category model.
We also include a backfill here with a simplified version
of Slug.for with deduplication to fill the slugs for already
created Category chat channels.
The channel slug is also now used for chat notifications,
and for the UI and navigation for chat. `slugifyChannel`
is still used, but now does the following fallback:
* Uses channel.slug if it is present
* Uses channel.escapedTitle if it is present
* Uses channel.title if it is present
In future we may want to remove this altogether
and always rely on the slug being present, but this
is currently not possible because we are not generating
slugs for DM channels at this point.
Clicking a link of the sidebar will now open the drawer and load the correct channel.
This solution should correctly solve these cases:
closing drawer, clicking sidebar channel, should open the drawer on correct channel
visiting /chat then visiting / and clicking sidebar channel, should open full page chat on correct channel
This commits makes sure we correctly wait for the end of the transition to reopen the drawer on the correct channel/view. Also fixes a bug when previous URL was `/` and causing a double transition.
Also adds end to end system tests to ensure navigation scenarios are working correctly. This separation will make it easier to implement state in/out from chat.
Doing DOM operations in finally would cause them to happen even when the request was a failure. Consequence of these DOM operations would be new request, which would also end up in a 404, and so on.
This commit simply moves the DOM operations in the then block where it should be safe to make.
This is a followup of the previous refactor where we created two new
models to handle all the dedicated logic that was present in the
`ChatChannel` model.
For the sake of consistency, `DMChannel` has been renamed to
`DirectMessageChannel` and the previous `DirectMessageChannel` model is
now named `DirectMessage`. This should help reasoning about direct
messages.
