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.
These were added in 7dd317b875
but are now consistently failing with described_class.chat_summary(user, {})
returning nil. Skipping for now because they are holding up other
things.
To reproduce failure run:
RSPEC_SEED=46586 bundle exec rake plugin:spec
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.
This refactoring simplifies ChatNotifier a bit. I wanted to drop
that argument for expand_direct_mentions too, but that needs
a bit deeper refactoring, so it's better to do it separately.

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.
Prior to this change `registered_bookmarkable` would return `nil` as `type` in `Bookmark.registered_bookmarkable_from_type(type)` would be `ChatMessage` and we registered a `Chat::Message` class.
This commit will now properly rely on each model `polymorphic_class_for(name)` to help us infer the proper type from a a `bookmarkable_type`.
Tests have also been added to ensure that creating/destroying chat message bookmarks is working correctly.
---
Longer explanation
Currently when you save a bookmark in the database, it's associated to another object through a polymorphic relationship, which will is represented by two columns: `bookmarkable_id` and `bookmarkable_type`. The `bookmarkable_id` contains the id of the relationship (a post ID for example) and the `bookmarkable_type` contains the type of the object as a string by default, (`"Post"` for example).
Chat plugin just started namespacing objects, as a result a model named `ChatMessage` is now named `Chat::Message`, to avoid complex and risky migrations we rely on methods provided by rails to alter the `bookmarkable_type` when we save it: we want to still save it as `"ChatMessage"` and not `"Chat::Message"`. And, to retrieve the correct model when we load the bookmark from the database: we want `"ChatMessage"` to load the `Chat::Message` model and not the `ChatMessage`model which doesn't exist anymore.
On top of this the bookmark codepath is allowing plugins to register types and will check against these types, so we alter this code path to be able to do a similar ChatMessage <-> Chat::Message dance and allow to check the type is valid. In the specific case of this commit, we were retrieving a `"ChatMessage"` bookmarkable_type from the DB and looking for it in the registered bookmarkable types which contain `Chat::Message` and not `ChatMessage`.
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. -->
Mentions are now displayed as using the non-cooked message which fixes
the problem. This is not ideal. I think we might want to rework how
these excerpts are created and rendered in the near future.

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).

This regressed with the commit fa543cd. Starting from that commit, we create mention records even if a user shouldn't be notified. So when sending emails, we should be making sure if a notification was actually created for a mention. This is essentially the whole fix that we need here. Tests will be provided in a following PR.
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.
This is just a little clean-up in tests. In the past, when creating a `chat_mention`
record, we always created a related notification. Starting from fa543cda
notifications and chat_mentions are fully decoupled from each other. So if we're
testing just chat mentions there is no need to fabricate notifications for them.
* DEV: Change sidebar header dropdown to use wait_for_animation
Introduced in 54351e1b8a, this
helper should remove the need to have to add the .animated
CSS class in JS for the sidebar.
* DEV: Revert spec change
`create_notification!` - creates a notification in the database, `send_notifications` sends desktop and mobile notifications. This PR moves some code to decouple these two tasks more explicitly. It only moves code without changing any behavior, and the job is covered with tests (see chat_notify_mentioned_spec).
- 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.
This is used when calling click_message_action_mobile to wait
for the message actions menu to finish animating up before
attempting to click on it using capybara. Without this, in
the time between capybara getting the x,y position of a menu
item to click on and the click being fired, the animating menu
can move that item out of the way.
With the new helper, we constantly compare x,y client rect positions
for the animating element and wait for them to stabilise. Once they
do, it means the animation is done, and it is safe to click on
anything within the element.
Re-enables mobile system specs for chat that were ignored because
of this.
Similar spirit to e195e6f614,
this moves the Bookmarkable registration to DiscoursePluginRegistry
so plugins which are not enabled do not register additional
bookmarkable classes.
Before this commit, we created a chat mention record only in case we wanted to send a notification about that mention to the user. Notifications were the only use case for the chat_mention db table. Now we want to use that table for other features, so we have to always create a chat_mention record.
- 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 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
Initially, the chat_mention db table was created to support notifications. So when creating
a `chat_mention` record we were always creating a related `notification` record. So did the
ChatMention fabricator.
Now we want to use the chat_mention db table in other scenarios. So we started decoupling
mentions from notification in 75b81b68.
This removes fabrication of Notifications from the ChatMention fabricator. We need to be able
to fabricate a ChatMention without a Notification.
This patch introduces a new `ServiceJob` class allowing the use of
`with_service` in jobs.
This way, it’s easier to use the chat service objects in jobs and
provides the same level of functionality than the one we have in
controllers.
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

Initially, the ChatMention model / db table was introduced to better support notifications (see discourse/discourse-chat@0801d10). That means that currently, we create a new chat_mention record only if a user will be notified about the mention.
Now we plan to start using the ChatMention model in other scenarios (for example for implementing user status on mentions) so we need to always create a new record in the chat_mention table. This PR does the first step into that direction by decoupling the logic for extracting and expanding mentions from the code related to notifications.
This doesn't change any behavior, only extracts code from ChatNotifier.
Before that change, footer of the sidebar was not visible.
Footer is very important, especially now, when add custom section button is located there.
Also, distance between chat input and keyboard were increased
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.
c.f. https://guides.emberjs.com/release/in-depth-topics/native-classes-in-depth/
We were calling the job with a symbol as one of the values:
```ruby
Jobs.enqueue(
:send_message_notifications,
chat_message_id: 1,
timestamp: Time.now.iso8601(6),
reason: :new,
)
```
Which is a bad pattern as when the job serialisation will happen, `:new` will become `"new"` and you have to deal with a string in your job and not a symbol, which can be confusing and lead to bugs.
This commit fixes the UpdateUserLastRead spec which was checking
for a message ID that did not exist -- this could fail at times
since message ID 2 could exist. Better to create + destroy a message
since then it's guaranteed we have a unique ID.
This also attempts to clarify a step that we expect to fail which
succeeds instead by adding another emoji next to the success tick and
an explanation text.
Also removes some uses of unless in Services::Base, we generally prefer
to use alternatives, since unless can be hard to parse in a lot of
cases.

which broke the functionality to click on a message
checkbox, hold shift, then click another one, and have

A typo was preventing a click on channel title when in drawer mode to correctly open the channel info in full page.
This commit fixes the typo and adds a test.

On mobile, we just need to add `min-width: 0` to
`chat-live-pane` so it will not overflow the grid
defined in `main-chat-outlet.chat-view`.
The overflow could be triggered by:
1. Replying on mobile to a really long chat message
2. Uploading > 2 files
Both of these situations are fixed.
This css was causing the view on mobile to take more space than the available width. This was particularly visible with uploads due to a bug preventing the overflow, this is also fixed.
This commit is expanding on previous work making everything chat working through an URL.
Improves drawer templates to be all URLs
Implements some kind of router for the drawer
Removes few remaining actions for opening channels
This commit introduces the skeleton of the chat thread UI. The
structure of the components looks like this. Its done this way
so the side panel can be used for other things as well if we wish,
not just for threads:
```
.main-chat-outlet
<ChatLivePane />
<ChatSidePanel>
<-- rendered with {{outlet}} -->
<ChatThread />
</ChatSidePanel>
```
Later on the `ChatThreadList` will be rendered here as well.
Now, when you go to a channel you can open a thread by clicking
on either the Open Thread message action button or by clicking on
the reply indicator. This will take you to a route like `chat/c/:slug/:channelId/t/:threadId`.
This works on mobile as well.
This commit includes basic serializers and routes for threads,
as well as a new `ChatThreadsManager` service in JS that caches
threads for a channel the same way the channel threads manager does.
The chat messages inside the thread are intentionally left out
until a later PR.
**NOTE: These changes are gated behind the site setting enable_experimental_chat_threaded_discussions
and the threading_enabled boolean on a ChatChannel**
We’re now using `contract` as the first step and validations for
mandatory parameters have been added.
To simplify specs a bit, we only assert the service contract is run as
expected without testing each validation case. We’re now testing the
contract itself in isolation.
This is a combined work of Martin Brennan, Loïc Guitaut, and Joffrey Jaffeux.

This commit implements a base service object when working in chat. The documentation is available at https://discourse.github.io/discourse/chat/backend/Chat/Service.html
Generating documentation has been made as part of this commit with a bigger goal in mind of generally making it easier to dive into the chat project.
Working with services generally involves 3 parts:
- The service object itself, which is a series of steps where few of them are specialized (model, transaction, policy)
```ruby
class UpdateAge
include Chat::Service::Base
model :user, :fetch_user
policy :can_see_user
contract
step :update_age
class Contract
attribute :age, :integer
end
def fetch_user(user_id:, **)
User.find_by(id: user_id)
end
def can_see_user(guardian:, **)
guardian.can_see_user(user)
end
def update_age(age:, **)
user.update!(age: age)
end
end
```
- The `with_service` controller helper, handling success and failure of the service within a service and making easy to return proper response to it from the controller
```ruby
def update
with_service(UpdateAge) do
on_success { render_serialized(result.user, BasicUserSerializer, root: "user") }
end
end
```
- Rspec matchers and steps inspector, improving the dev experience while creating specs for a service
```ruby
RSpec.describe(UpdateAge) do
subject(:result) do
described_class.call(guardian: guardian, user_id: user.id, age: age)
end
fab!(:user) { Fabricate(:user) }

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.

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
* 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.

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

We've had the UploadReference table for some time now in core,
but it was added after ChatUpload was and chat was just never
moved over to this new system.
This commit changes all chat code dealing with uploads to create/
update/delete/query UploadReference records instead of ChatUpload
records for consistency. At a later date we will drop the ChatUpload
table, but for now keeping it for data backup.
The migration + post migration are the same, we need both in case
any chat uploads are added/removed during deploy.
Learn more about skidding here: https://popper.js.org/docs/v2/modifiers/offset/#skidding-1
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
Prior to this fix trashed channels would still prevent a channel with the same slug to be created. This commit generates a new slug on trash and frees the slug for future usage.
The format used for the slug is: `YYYYMMDD-HHMM-OLD_SLUG-deleted` truncated to the max length of a channel name.
This commit allows us to set the channel slug when creating new chat
channels. As well as this, it introduces a new `SlugsController` which can
generate a slug using `Slug.for` and a name string for input. We call this
after the user finishes typing the channel name (debounced) and fill in
the autogenerated slug in the background, and update the slug input
placeholder.
This autogenerated slug is used by default, but if the user writes anything
else in the input it will be used instead.
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.
Added in c2013865d7,
this migration was supposed to only turn off the hashtag
setting for existing sites (since that was the old default)
but its doing it for new ones too because we run all migrations
on new sites.
Instead, we should only run this if the first migration was
only just created, meaning its a new site.
If the enable_experimental_hashtag_autocomplete setting is
enabled, then we should autolink hashtag references to the
archived channels (e.g. #blah::channel) for a nicer UX, and
just show the channel name if not (since doing #channelName
can lead to weird inconsistent results).
The spec was flaky because it was dependent on order,
when usernames got high enough sequence numbers in them
we would get this error:
> expected to find text "bruce99, bruce100" in "bruce100, bruce99"
Also move selectors into page object and use them in the
spec instead.
There was an issue with channel archiving, where at times the topic
creation could fail which left the archive in a bad state, as read-only
instead of archived. This commit does several things:
* Changes the ChatChannelArchiveService to validate the topic being
created first and if it is not valid report the topic creation errors
in the PM we send to the user
* Changes the UI message in the channel with the archive status to reflect
that topic creation failed
* Validate the new topic when starting the archive process from the UI,
and show the validation errors to the user straight away instead of
creating the archive record and starting the process
This also fixes another issue in the discourse_dev config which was
failing because YAML parsing does not enable all classes by default now,
which was making the seeding rake task for chat fail.
* Firefox now finally returns PerformanceMeasure from performance.measure
* Some TODOs were really more NOTE or FIXME material or no longer relevant
* retain_hours is not needed in ExternalUploadsManager, it doesn't seem like anywhere in the UI sends this as a param for uploads
* https://github.com/discourse/discourse/pull/18413 was merged so we can remove JS test workaround for settings
* FIX: Channel archive N1 when serializing current user
The `ChatChannelSerializer` serializes the archive for the
channel if it is present, however this was causing an N1 for
the current user serializer in the case of DM channels, which
were not doing `includes(:chat_channel_archive)` in the
`ChatChannelFetcher`.
DM channels cannot be archived, so we can just never try to serialize
the archive for DM channels in `ChatChannelSerializer`, which
removes the N1.
* DEV: Add N1 performance spec for latest.html preloading
We modify current user serializer in chat, so it's a good
idea to have some N1 performance specs to avoid regressions
here.
In certain cases, like when `SiteSetting.slug_generation_method`
is set to `none` with certain locales, the autogenerated chat
channel slugs will end up blank. This was causing errors in
unrelated jobs calling `update!` on the channel. Instead, we
should just copy Category behaviour, which does not error
if the autogenerated slug ends up blank. We already allow
for this with chat channel URLs, using `-` in place of the
missing slug.
The problem here was that if your input has an Enter
listener (such as the chat message input) and the
`fill_in(with: str)` string has a `\n` at the end, this
is treated as an Enter keypress, so this `fill_in` was
submitting the chat message.
This commit fixes an issue where the chat message bookmarks
did not respect the user's `bookmark_auto_delete_preference`
which they select in their user preference page.
Also, it changes the default for that value to "keep bookmark and clear reminder"
rather than "never", which ends up leaving a lot of expired bookmark
reminders around which are a pain to clean up.
`last_message_sent_at` has a `NOT_NULL` constraint in the DB so it should be safe to use for sorting.
This was causing two flakeys:
```
1) UserNotifications.chat_summary with public channel email subject with regular mentions includes both channel titles when there are exactly two with unread mentions
Failure/Error: example.run
expected: "[Discourse] New message in Random 62 and Test channel"
got: "[Discourse] New message in Test channel and Random 62"
(compared using ==)
# ./plugins/chat/spec/mailers/user_notifications_spec.rb:203:in `block (6 levels) in <main>'

# ./vendor/bundle/ruby/3.1.0/gems/webmock-3.18.1/lib/webmock/rspec.rb:37:in `block (2 levels) in <top (required)>'
2) UserNotifications.chat_summary with public channel email subject with regular mentions displays a count when there are more than two channels with unread mentions
Failure/Error: example.run
expected: "[Discourse] New message in Random 62 and 2 others"
got: "[Discourse] New message in Test channel 0 and 2 others"
(compared using ==)

# ./vendor/bundle/ruby/3.1.0/gems/webmock-3.18.1/lib/webmock/rspec.rb:37:in `block (2 levels) in <top (required)>'
```
This commit is a series of fixes to improve stability of system tests following the use of threadsafe:
* Jobs.run_immediately in before block was causing issues
* During test a js error could be caused by an undefined this.details in chat-live-pane
* Apply the chat composer click trick everywhere when sending a message, it ensures we are not hiding anything with autocomplete
* There was another case not using send_message yet
This PR removes the limit added to max_users_notified_per_group_mention during #19034 and improve the performance when expanding mentions for large channel or groups by removing some N+1 queries and making the whole process async.
* Fully async chat message notifications
* Remove mention setting limit and get rid of N+1 queries
It should fix flakeys we have due to using_session. This commit is also fixing tests which were failing constantly with treadsafe enabled.
A test has also bene skipped as the issue couldn't be found so far.

- improves UI by displaying channel status on it's own line
- ensures channel status is correctly updated right after the request on frontend
- adds status on info page
Recent changes surfaced the various issues with this codepath:
- we were not correctly reseting `messageLookup` leading to us trying to scroll to a non existing message in the view
- we were calling markAsRead which would scroll to the bottom, even if we had a target message
- we were not debouncing fetchMessages, which could cause multiple reload of the messages when loading it with a targetMessageId: first fetch from last read and then immediately fetch from targetMessageId
- other naming inconsistencies
- not handling drawer
This commit also adds tests for classic scenarios related to this use case.
I could repro the same failure by doing: `page.driver.browser.network_conditions = { offline: false, latency: 3000, throughput: 0 }`
Wait shouldn't be needed as we wait for selector, but I couldn't find a better solution on this case for now.
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.
The way our markdown raw_html hoisting worked, we only
supported one level of hoisting the HTML content. However
when nesting [chat] transcript BBCode we need to allow
for multiple levels of it. This commit changes opts.discourse.hoisted
to be more constant, and the GUID keys that have the hoisted
content are only deleted by unhoistForCooked rather than
the cook function itself, which prematurely deletes them
when they are needed further down the line.
Honestly seems like it's being in some weird loop for
discourse/hashtag_autocomplete_spec.rb for this:
```ruby
within topic_page.post_by_number(2) do
cooked_hashtags = page.all(".hashtag-cooked", count: 2)
expect(cooked_hashtags[0]["outerHTML"]).to eq(<<~HTML.chomp)
<a class=\"hashtag-cooked\" href=\"#{category.url}\" data-type=\"category\" data-slug=\"cool-cat\"><svg class=\"fa d-icon d-icon-folder svg-icon svg-node\"><use href=\"#folder\"></use></svg><span>Cool Category</span></a>
HTML
expect(cooked_hashtags[1]["outerHTML"]).to eq(<<~HTML.chomp)
<a class=\"hashtag-cooked\" href=\"#{tag.url}\" data-type=\"tag\" data-slug=\"cooltag\"><svg class=\"fa d-icon d-icon-tag svg-icon svg-node\"><use href=\"#tag\"></use></svg><span>cooltag</span></a>
HTML
end
```
I see this many times in the full logs with `SELENIUM_VERBOSE_DRIVER_LOGS=1`:
```
COMMAND FindElements {
"using": "css selector",
"value": "#post_2"
}
Followed by:
COMMAND FindChildElements {

```
Over and over and over, there are 58 such occurrences. I am beginning to
think `within` is just poison that should be avoided.
Previously, calling `sign_in` would cause the browser to be redirected to `/`, and would cause the Ember app to boot. We would then call `visit()`, causing the app to boot for a second time.
This commit adds a `redirect=false` option to the `/session/username/become` route. This avoids the unnecessary boot of the app, and leads to significantly faster system spec run times.
In local testing, this takes the full system-spec suite for chat from ~6min to ~4min.
1. `test()` and `render()` instead of `componentTest()`
2. Angle brackets
3. `strictEqual()`/`true()`/`false()` assertions
This removes all remaining uses of `componentTest` from core
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.
The client already has all the information about the current user so
there is no need for us to be serializing the current `User` object each
time per channel that is preloaded.
In production, profiling shows that this unneeded serializing
adds a roughly 5% overhead to a request.
- 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
<!-- NOTE: All pull requests should have tests (rspec in Ruby, qunit in JavaScript). If your code does not include test coverage, please include an explanation of why it was omitted. -->
Prior to this change, each request executed 2 Redis calls per chat channel
that was loaded. The number of Redis calls quickly adds up once a user
is following multiple channels.
This commit adds an index for the query which the chat plugin executes
multiple times when preloading user data in `Chat::ChatChannelFetcher.unread_counts`.
Sample query plan from a query I grabbed from one of our production
instance.
