Previously, there was an issue where closing the message actions menu on mobile would unintentionally trigger a click event on an element below it, such as a thread indicator or a reaction. With the recent fix, this problem has been resolved. Now, when you close the menu, it will no longer interfere with or activate any elements positioned underneath it.
One user can create a post or chat message with a hashtag they
have permission to use, but then when other users look at that
post they will see an empty space next to the hashtag because they
do not have the permission to load the colors in CSS classes for
the related category.
This fixes the issue by adding a default color with a special
CSS class if the user doesn't have permission to see the linked
channel/category on the hashtag.
Few weeks ago we implemented `onPresenceChangeCallback` to re-sync chat channels state when going back to a long time inactive tab. This codepath however contained a bug as we were reseting all subscriptions but only restarting global subscriptions and not per channel subscriptions.
This commit should correctly ensure we correctly do so. It's sadly very hard to test time related changes in system specs.

What is the problem?
We were calling out to methods that calls `has_css?` or `has_selector?`
which returns a boolean. Since we are not using the return value, it
means the methods can be deemed unnecessary. However, we do want those
checks and this commit adds the necessarily assertions to make use of
the return values.
When a user type a message with mentions, the autocomplete popup
may suggest users or groups. We were adding all these object to
the `currentMessage.mentionedUsers` collection, while we should
have been adding only users. A group added to that collection led to
the error later when trying to update user status on mentions.
This will make it simpler to work with this code. This also can make this code more stable and increase stability of our test suite.
Cooked message now will be available immediately after cooking, it wasn't the case before:
await message.cook();
const cooked = message.cooked;
This also removes a call to `message.cook()` from message fabricator. Alternatively we may leave the call there and make the fabricator function async, but I fill it's better this way. If someone needs to test something related to cooked message, they can either pass cooked text to fabricator:
message = fabricators.message({ cooked: "<p>cooked</p>" });
or call `message.cook()` after fabrication:
message = fabricators.message({ message: "raw message" });
await message.cook()
This reverts commit ddf4ecba04.

* FEATURE: reduce avatar sizes to 6 from 20
This PR introduces 3 changes:
1. SiteSetting.avatar_sizes, now does what is says on the tin.
previously it would introduce a large number of extra sizes, to allow for
various DPIs. Instead we now trust the admin with the size list.
2. When `avatar_sizes` changes, we ensure consistency and remove resized
avatars that are not longer allowed per site setting. This happens on the
12 hourly job and limited out of the box to 20k cleanups per cycle, given
this may reach out to AWS 20k times to remove things.
3.Our default avatar sizes are now "24|48|72|96|144|288" these sizes were
very specifically picked to limit amount of bluriness introduced by webkit.
Our avatars are already blurry due to 1px border, so this corrects old blur.
This change heavily reduces storage required by forums which simplifies
site moves and more.

- ensures buttons are aligned to the bottom
- makes the emoji icon tertiary as initially intended
- correctly sets the icon scale of the sending button
- Made the emoji btn blue when composer is focused
- Moved everything chat-composer-button to its own file and BEM-ified it and making the choice to only work with our own is-disabled definition instead of with the attribute :disabled, for consistency
This should fix this failure:
```
Failures:
1) Thread list in side panel | full page when there are no threads that the user is participating in shows a message
Failure/Error: measurement = Benchmark.measure { example.run }
expected to find text "You are not participating in any threads in this channel." in "Community\nEverything\nMy Posts\nMore\nMessages\nInbox\nChannels\nRandom 25\nPersonal chat\nRandom 25\nShowing all messages\nOngoing discussions"
```
The screenshot failure was clearly showing the spinner still being present.
If the drawer receives an unexpected route, attempt to show the index. This is probably a more serious issue with subfolder but should limit the effects.
Rescuing them still makes timing-out tests fail but doesn't break `after` spec cleanup (which could trigger more errors) Using custom error class to avoid any other possible timeout-catching code.
Also:
* remove an unnecessary `.select { |x| x.size > 0 }`
* fix a typo in a test title
We were calling reset without the proper params which was causing errors in the console. This commit does the following changes:
- ensures `composer.cancel()` is the only way to cancel editing/reply
- adds a `draftSaved` property to chat message to allow for better tests
- writes a spec to ensure the flow is correct
- adds more page objects for better tests
- homogenize the default state of objects on chat message

Editing a message to an empty string and sending it, will delete it.
This commit also refactors a lot of channel/thread composer shortcuts specs.
---
This commit also includes various spec fixes which have been flakey while finishing this pull request.
These specs were disabled in 786f7503. While investigating this, I found out that at some point `:user_membership` got deleted. It's hard to tell why exactly without investing more time, but it seems using `let!` instead of `fab!` solves the issue.
If in the future we decide to investigate why these tests were flaky with `fab!` to reproduce the failure run:
LOAD_PLUGINS=1 rspec --seed 46586 plugins/chat/spec/mailers/user_notifications_spec.rb
This changes the thread header positioning of the
unread indicator to match the designs based on the route:
1. When the channel is open, show the indicator of # unread
threads with the icon
2. When the threads list is open, show no indicator since
you are on the list and can see which threads are unread
3. When a single thread is open, show the unread threads
indicator along with a left < back button, with a label
to show that this goes back to ongoing discussions
Drawer changes to come in another PR.
Why is this change required?
In the `PageObjects::Components::Chat::Messages#has_no_message?` method,
it ended up calling `has_selector` when trying to assert that the
selector is not present. This is an anti-pattern which results in us
waiting the full Capybara default wait time
What is this change required?
In the `chat/spec/system/transcript_spec.rb` test, there is a helper
method that uses `page.has_css?` in a conditional but it do not
specify a wait time and hence the default Capybara default max wait
time is used. However, there is no need for us to be waiting here so
we specify the `wait: 0` option.
Followup 55ef2d0698.
In the cases where the user has no last_read_message_id for
a channel, we want to make sure that a page_size is set for
the ChannelViewBuilder + MessagesQuery, otherwise we end up
loading way more messages than needed (the additional message
loading was fixed in the last commit).
This commit introduces a couple of changes:
1. When editing a chat channel's slug, we were using `this.model.set("title", title)` when the `set`
function does not exist. This was actually throwing the error in the
"can edit slug" system test where the modal was not closed after
saving and was flashing an error.
2. Introduce `PageObjects::Pages::ChatChannelAbout` and
`PageObjects::Modals::ChatChannelEdit` page object to encapsulate
logic better.
When a thread is created / a new message is created in the
thread, we want to make sure that the original message user
has a membership for that thread, otherwise they will not
receive unread indicators for messages in the thread.
This commit attempts to fix the case where the messages loaded initially don't fill the screen. It would prevent user to scroll and as a result to load more.
There are multiple fixes in this commit:
- the main fix is removing this code which was preventing the actual fill:
```javascript
// prevents an edge case where user clicks bottom arrow
// just after scrolling to top
if (loadingPast && this.#isAtBottom()) {
return;
}
```
- ensures we always give a page site to the `chatApi.channel(...)` call if we have one, in the current state when `fetchFromLastRead` was `true` we would not set `args.page_size`
- ensures the `query_paginated_messages` is having a valid page size, which is not nil and not > `MAX_PAGE_SIZE`
- write a spec for the autofill, it was a challenging spec to write but it should give us the confidence we need here
Since 5cce829 and the new
channel view builder, we have no need of these obsolete
routes which have way too much logic in the controller, which
has been superseded by the view builder anyway.
Remove the routes and update the channel message loading to use it.
* Moved the settings cog from thread list to thread and
put it in a new header component
* Remove thread original message component, no longer needed
and the list item and thread indicator styles/content
will be quite different
* Start adding content (unread indicator etc.) to the thread
list item and changing structure to be more like designs
* Serialize the last thread reply when opening the thread index,
show in list and update with message bus
In some cases activeChannel can be null so this will error,
also it is limiting to have this code in chatApi. Instead
move to the threads manager, and also lean on channelsManager.find
to get the channel from the cache instead, which will not error.
The current behavior is to close drawer when pressing escape inside the input.
After this change, first escape will blur the input, and second escape will close the drawer.
This commit also refactors the whole shortcuts for drawer system spec.
Followup to d4a5b79592,
this introduced an N1 because every message in the list
we had to query users for the mentions and then the user's
status too. Instead we can just include both in Chat::MessagesQuery.
#### FIX: Do not use client lastReadMessageId when fetching channel messages
We had an issue where the following happened:
1. User opened channel and saw the last message, and we set the
lastReadMessageId on the server and the client
2. User navigated to another channel
3. Another user deleted the message in the original channel
4. The first user navigated back to the original channel before
the MessageBus event for the deleted message arrived, and got
a 404 error because we were sending the deleted lastReadMessageId as
target_message_id to the channel controller.
Instead of this which is a bit flaky and is hard to cover all
the issues for, instead we can pass a fetch_from_last_read boolean
param to the channels controller, and just get the user's
last_read_message_id straight from the database to use for the
target_message_id. This gets rid of any sources of race conditions
or lack of updates from MessageBus.
#### FIX: Include missing memberships for thread tracking publish
When we publish the channel/message tracking state for a
user and that message was a thread reply the publisher
was erroring because we were not telling Chat::TrackingStateReportQuery
to return missing memberships (which have zeroed out unread counts)
as well, which is what we do for the channel tracking state here.
Also just make sure that the TrackingStateReport does not error
when passed an ID it doesn't have data for.
This flakey has been very visible by the new headless chrome. The problem was that after moving a message we automatically redirect to the channel where the message has been moved to. However, we were not explicitly waiting for this transition and a result it could happen that we attempt to check the presence of the message on the channel page before the redirect actually happened.
The various naming changes are due to an early mistake we made in chat specs to use `chat` as the variable name for the page object which prevents to use the automatic path `chat.channel_path(...)`.

This commit follows up b6c5a2da08
by serializing the user's thread memberships in these cases:
1. When we do the initial channel fetch with messages, we get
all threads and all the user's thread memberships for those
messages.
2. When the thread list is fetched, we get all the user's memberships
in that list.
3. When the single thread is fetched, either from opening it from
the list, an OM indicator, or just from doing .find() on the
manager when a new MessageBus message comes in
This will let us track the lastReadMessageId on the client, and
will also let us fix an issue where the unread indicator in the
channel header was incrementing for every thread that got a
new message, regardless of whether the user was a member.
This patch introduces policy objects to chat services. It allows putting
more complex logic in a dedicated class, which will make services
thinner. It also allows providing a reason why the policy failed.
Some change has been made to the service runner too to use more easily
these new policy objects: when matching a failing policy (or any failing
step actually), the result object is now provided to the block. This
way, instead of having to access the reason why the policy failed by
doing `result["result.policy.policy_name"].reason` inside the block,
this one can be simply written like this:
```ruby
on_failed_policy(:policy_name) { |policy| policy.reason }
```
This commit adds the thread index and individual thread
in the index list unread indicators, and wires up the message
bus events to mark the threads as read/unread when:
1. People send a new message in the thread
2. The user marks a thread as read
There are several hacky parts and TODOs to cover before
this is more functional:
1. We need to flesh out the thread scrolling and message
visibility behaviour. Currently if you scroll to the end
of the thread it will just mark the whole thread read
unconditionally.
2. We need to send down the thread current user membership
along with the last read message ID to the client and
update that with read state.
3. We need to handle the sidebar unread dot for when threads
are unread in the channel and clear it based on when the
channel was last viewed.
4. We need to show some indicator of thread unreads on the
thread indicators on original messages.
5. UI improvements to make the experience nicer and more
like the actual design rather than just placeholders.
But, the basic premise around incrementing/decrementing the
thread overview count and showing which thread is unread
in the list is working as intended.
This commit regroups 3 changes
- serializes channel ID and json draft when calling the debouncer instead of inside the debounced function, it seems very unlikely to happen, but in a case where the debouncing wouldn't be canceled and the new message not set yet, we could save the draft on an invalid channel
- cancel persist draft handler when changing channel
- ensures we exit early when channel is not set
Very fast or specific mouse moves could allow to leave a message actions menu without reseting the active message. This commit should ensure we correctly catch this event.
No test as it's hard and not reliable to reproduce these in a test.
This should also make `message_notifications_with_sidebar_spec.rb` more resilient as we are now checking for `is-persisted` class instead of checking for the absence of `is-staged`.
This commit attempts to correctly change draft when the channel changes. It moves responsibility to the composer instead of the channel.
A new service `chatDraftsManager` is being introduced here to allow finer control and pave the way for future thread draft support.
These changes also now allow an editing message to be stored as a draft.
This PR adds status to mentions in chat and makes those mentions receive live updates.
There are known unfinished part in this implementation: when posting a message, status on mentions on that message appears immediately, but only if a user used autocomplete when typing the message. If user copy and paste a message with mentions into chat composer, those mentions won't have user status on them.
PRs with fixes for both problems are following soon.
Preparations for this PR that were made previously include:
- DEV: correct a relationship – a chat message may have several mentions 0dcfd7ddec
- DEV: extract the logic for extracting and expanding mentions from ChatNotifier 75b81b6854
- DEV: Always create chat mention records fa543cda06
- DEV: better split create_notification! and send_notifications logic e292c45924
- DEV: more tests for mentions when updating chat messages e7292e1682
- DEV: extract updating status on mentions into a lib function e49d338c21
- DEV: Create and update chat message mentions earlier 35a414bb38
- DEV: Create a chat_mention record when self mentioning 2703f2311a
- DEV: When deleting a chat message, do not delete mention records f4fde4e49b
In the ChannelViewBuilder, we introduced a check to see if
the target message exists, which errors if the message has
been trashed. However if the user is the creator of the message
or admin then they are able to see trashed messages, so
we need to take this into account.
Followup to c908eeacc9
Instead of using the latest message ID in the channel, which
could cause issues if you have an earlier last read message ID
that matches the deleted one, instead we use the first non-deleted
message that comes before the deleted message by ID.
Followup ae3231e140, when a
message is trashed we already update the lastReadMessageId of
all users in the channel to the latest non-deleted message on
the server side. However we didn't propagate this to the client,
so in some cases when we did the following:
1. Delete the last message in the channel
2. Switch to another channel
3. Switch back to the original
We would get a 404 error from the target message ID being looked
up still being the old lastReadMessageId (now deleted) for the
user's channel membership.
All we need to do is send the last not-deleted message ID for
the channel (or thread) to all the member users.
Before this commit the following actions would have shown the issue:
- visit a thread
- changes the width of the side panel
- open threads list
- the size has reverted to previous state
This was caused by the width change to not correctly be tracked.
It easier to check for presence in this case that to check for something not present, as depending on performance of the machine running the test this could take sometime to be changed and the test would fail.
This issue was especially visible in tests. the `@debounce(100)` was not cancelled when changing channel which was causing 404s as we were trying to load messages on a channel which was deleted as the channel has been destroyed at the end of the test.
This is still not a perfect solution, as we can only cancel the start of `fetchMessages`, but we can't cancel the actual `chatApi.channel` request which result can potentially happens after channel changed, which we try to mitigate with various checks on to ensure visible channel == loaded messages channel.
This commit also tries to make handler naming and cancelling more consistent.

This commit makes it easier to ensure each button have a similar behavior: hover, disabled, focus...
It also removes some dead code (__inline-button) and fixes a bug where the emoji button didnt have the right un-focused color (it was more visible than it should.
This commit makes some fundamental changes to how hashtag cooking and
icon generation works in the new experimental hashtag autocomplete mode.
Previously we cooked the appropriate SVG icon with the cooked hashtag,
though this has proved inflexible especially for theming purposes.
Instead, we now cook a data-ID attribute with the hashtag and add a new
span as an icon placeholder. This is replaced on the client side with an
icon (or a square span in the case of categories) on the client side via
the decorateCooked API for posts and chat messages.
This client side logic uses the generated hashtag, category, and channel
CSS classes added in a previous commit.
This is missing changes to the sidebar to use the new generated CSS
classes and also colors and the split square for categories in the
hashtag autocomplete menu -- I will tackle this in a separate PR so it
is clearer.
- few improved alignments
- displays emoji picker button inline on desktop
- keeps composer focused when focusing dropdown button
- align buttons to bottom when increasing height of textarea
- max-height of textarea is now linked to the height of the screen

This commit moves message lookup and querying to the
/chat/api/channel/:id endpoint and adds the ability
to query the tracking state overview for threads as well
as the threads and thread tracking state for any thread
original messages found.
This will allow us to get an initial overview of thread
tracking for a user when they first enter a channel, rather
than pre-emptively loading N threads and tracking state
for those across all channels on the current user serializer,
which would be expensive.
This initial overview will be used in subsequent PRs to
flesh out the thread unread indicators in the UI.
This also moves many chunks of code that were in services
to reusable Query classes, since use of services inside
services is discouraged.
Regressed in eec10efc3d. It means that backend plugin spec failures in CI were not failing the spec suite.

Wrap scroll to bottom inside a next block to ensure the message has correctly been added to the array before actually attempt to scroll.
This commit also removes an unnecessary line which was essentially adding the message two times with no real consequences as we are uniq on ID.
- uses current user as user for fabricators, allows for correct avatar image and presence indicator
- uses a non existing channel ID to avoid setting a draft of an existing channel
- attempts to make color toggle more reliable
- Improves styleguide support
- Adds toggle color scheme to styleguide
- Adds properties mutators to styleguide
- Attempts to quit a session as soon as done with it in system specs, this should at least free resources faster
- Refactors fabricators to simplify them
- Adds more fabricators (uploads for example)
- Starts implementing components pattern in system specs
- Uses Chat::Message creator to create messages in system specs, this should help to have more real specs as the side effects should now happen
Followup from 9953a6edd9,
which broke an issue fixed in e8d6277062.
In the refactor we did not update the place where we resync
channel tracking based on onPresenceChange to use the new
tracking object we added to the serializer, and to directly
update channel.tracking
We had safe-area-inset-bottom still set at a wrong place which was causing issues but was also useful to some cases. This commit removes it and ensures the affected cases are corrected.
This is only the first steps of a redesign
- redesigns the buttons to have a larger hitzone
- generally bigger composer
- clicking near textarea focuses the input
- relies on the fact that safe-area-inset-bottom is set globally and doesn’t need to be set in sub components
This moves chat tracking state calculation for channels
and threads into a central Chat::TrackingStateManager service, that
serves a similar purpose to the TopicTrackingState model
in core.
This service calls down to these query classes:
* ThreadUnreadsQuery
* ChannelUnreadsQuery
To get the unread_count and mention_count for the appropriate
channels and threads.
As well as this, this commit refactors the client-side chat
tracking state.
Now, there is a central ChatTrackingStateManager Ember Service
so all tracking is accessible and can be counted from one place,
which can also initialize tracking from an initial payload.
The actual tracking counts are now maintained in a ChatTrackingState
class that is initialized on the `.tracking` property of both channel and
thread objects.
This removes the attributes on UserChatChannelMembership and decoration
of said membership from ChannelFetcher, preferring instead to have an additional
object for tracking in the JSON.
* DEV: add new thread icon
* FIX: Use new thread icon, fix typo in SVG
UX: move the thread list icon to the right of
the collapse button

This commit also removes safe-area-inset-bottom when keyboard is displayed to avoid having a taller than needed space between composer and replying indicator.
Before this commit chat was applying a fixed height on everything under the `/chat` route. It's only really needed on the channel page with the composer at the bottom of the page.
This commits makes the following changes:
- moves height limitation from `#main-outlet-wrapper` to `.chat-channel`
- makes browse channel page and members list page full height and rely on main document scrollbar
- adds height computation for draft header and direct message creator block to ensure the height is correct when creating a draft channel
- makes chat index full height to rely on the browser scrollbar. As a result the <kbd> + </kbd> button used on mobile to create a direct message as been moved out of `<ChannelsList>` into the chat index template
- sidebar height was relying on chat setting a max height, as a result the height computation of sidebar has been changed to work correctly, especially with an opened keyboard on mobile or ipad
Hard to write a test for this behavior, this is a micro optimisation which doesn’t change the behavior but only makes it smoother by happening right before async request.
The failure screenshot shows the message is on screen while the error is:
```
Failure/Error: example.run
expected to find text "My favorite message" in "Community\nEverything\nMy Posts\nMore\nMessages\nInbox\nChannels\nPolitics 1\nPersonal chat\nPolitics 1". (However, it was found 1 time including non-visible text.)
```
I expect the arrow element might e slightly hiding the link, but not 100% sure of this.
When using `navigator.virtualKeyboard.overlaysContent = false` we can rely on using only the resize event. Also attempts to no over trigger `setProperty` when value didn't change.
A follow-up to 54b2a85b. That commit didn't fix the issue because the to_notify hash that we return from the notify_edit method isn't used anywhere apart from tests (that's confusing, we're going to fix that soon).
This issue was for example possibly causing the last visit indicator to be reset by `sent` messages events.
The following was happening:
- a user (bob) had a last message bus ID of 1 on a channel (id:1) subscription
- bob then go to another channel (id:2), unsubscribing from updates of channel (id:1)
- another user (laura) then send messages to channel (id:1)
- bob goes back to channel (id:1)
At this point we we doing in the same sequence:
- loading channel with messages, getting a new last message bus id
- subscribing to updates using the last known message bus id
Most of the times we were lucky enough for this to work (no events while away, or just got the new id in time...) but it was also very likely to do a double fetch of messages as MessageBus would think we were late.
A chat message may be restored later, so we shouldn't be deleting `chat_mentions` records for it.
But we still have to remove notifications (see 082cd139).
This commit fixes the shift+click multi selection in threads. We were not correctly using the manager of the message and would attempt to find messages in the channel instead of the thread.
The `activeThread` was also not correctly set sometimes.
Also adds tests for message selection in threads.
In the past, we create a `chat_mention` records only when we wanted to notify a user about a mention. Since we don't send notifications when a user mentioning himself, we didn't create a `chat_mention` records in those cases.
Now we use `chat_mentions` records in other scenarios too, so when a user is mentioning himself we want to:
1. Create a `chat_mention` record for that mention
2. Do not create a notification for that mention
When the user sends a message in a thread, we want to
create a membership for them in the background (default
to notification level of Watching) so we can track whether
they have read the thread.
Then, for now since we don't have granular message reading/
scrolling in the thread panel, we just update the thread
last_read_message_id for the user to the latest reply in the
thread when they open the thread panel. This at least will
mark the thread as read.
In future PRs we want to show the blue dot indicator in various
places in the UI for unread threads which will also require
some MessageBus functionality.
This takes into account the same issue fixed for channels
in ae3231e140
We were combining both solutions which was apparently causing issues from chrome 113 on Android at least.
The commit will now use `geometrychange` (android) only when available and fallback to `visualViewport` otherwise (iOS).
This feature adds the replying indicator in threads, it uses the same `/chat-reply/CHANNEL_ID` prefix than the channel composer replying indicator as we don't have specific right on threads ATM (if you can access channel, you can access thread). Thread will however use a presence channel name of the following format: `/chat-reply/CHANNEL_ID/thread/THREAD_ID`
This commit also simplifies the computation of `users` to eventually avoid a race-condition leading to a leak of the indicator in another channel/thread.
<!-- 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. -->
When setting DISCOURSE_ZEITWERK_EAGER_LOAD=1 to enable
eager loading the previous solution to adding chat_levels
to the core NotificationLevels would break with a module
loading error (c.f. cc2570fce3)
We don't actually _need_ to extend the core class, we can just
make our own for chat, let's do this instead.
This will enable us to begin work on user tracking
state for a thread so we can show thread-specific
unreads and mentions indicators. In this case are following
the core notification_level paradigm rather than the solution
UserChatChannelMembership went with, and eventually we
will want to refactor the other table to match this as well.

Since we have channel message retention which deletes
messages, we can end up with cases where the thread
is still around but the message is deleted. We will
