We did some testing and saw that making one query per month is
cheaper than querying all chat messages at ones. Note that even
though the export job will be performing one query per month,
the exported messages will be streamed into a single CSV file, so
nothing changes from the user's point of view.
This is extracted from #22390.
This patch introduces a scope to avoid duplication and a new method,
`Chat::Channel.find_by_id_or_slug` to allow finding a channel either by
its id or by its slug (or its category slug).
`Jobs::AutoJoinChannelBatch` was holding a lot of logic which should be in a service. Moreover, this refactoring is the opportunity to address a bug which could cause a duplicate key error.
From now when trying to insert a new membership it won't fail if a membership is already present.
Example error:
```
Job exception: ERROR: duplicate key value violates unique constraint "user_chat_channel_unique_memberships"
DETAIL: Key (user_id, chat_channel_id)=(1, 2) already exists.

Prior to this commit we were loading a large number of thread messages without any pagination. This commit attempts to fix this and also improves the following points:
- code sharing between channels and threads:
Attempts to reuse/share the code use in channels for threads. To make it possible part of this code has been extracted in dedicated helpers or has been improved to reduce the duplication needed.
Examples of extracted helpers:
- `stackingContextFix`: the ios hack for rendering bug when momentum scrolling is interrupted
- `scrollListToMessage`, `scrollListToTop`, `scrollListToBottom`: a series of helper to correctly scroll to a specific position in the list of messages
- better general performance of listing messages:
One of the main changes which has been made is to remove the computation of visible message during scroll, it will only happen when needed (update last read for example). This constant recomputation of `message.visible` on intersection observer event while scrolling was consuming a lot of CPU time.
I was only able to get one failure out of 100 tries, this failure didn't get me more info. My best guess ATM is that sometimes, the first session was still loading while receiving the reaction and created some unexpected situation.
The commit attempts to start the "check" session before the session making the reaction hoping that will be enough to prevent this case, if this is the issue.
This is extracted from #22390.
This patch simplifies a little how we handle uploads in chat, relying on
ActiveRecord mechanisms instead of calling custom methods.
This also makes `Chat::Message#validate_message` a “real” AR validation,
meaning it will run automatically when `#valid?` is called.
This is extracted from #22390.
This patch adds a new `optional` option to the `model` step. This
means if an optional model returns something blank (`nil` or an empty
collection) then the service won’t fail and will execute the next step.
However if a model is properly returned, the step will try to check if
it is valid or not (if it responds to `#invalid?`). If the model isn’t
valid, then the step will fail (so no change here).
Someone who cannot chat is also not able to join chat channels,
so we may not check all the time user.can_chat? && user.can_join_chat_channel?
and just call user.can_join_chat_channel? instead.

The above incorrectly removed the channel unread count in
the mobile/drawer channel list when the user has mentions
(meaning the unreads are urgent). This commit adds it
back and refactors system specs a little.
Why this change?
The test being changed in question has been flaky on our CI. However, we
are unable to view the screenshot of why it failed because
ActionDispatch will only take a screenshot of the default session upon
failure. At the same time, taking screenshot of all sessions
automatically upon failure is not possible via the official Capybara or
Rails APIs at the moment. Therefore, we're changing this system test to
avoid using two custom session and instead have the main assertion use
the default session such that any failures will provide us with a
screenshot.
This commit fixes two issues with the thread list:
1. All threads were being shown regardless of whether the user had
a membership in the thread. This was happening because the list
and the channel share the same thread store, so if the channel
had OMs with threads we would load them and they showed in the list.
2. Threads created by the user from a staged thread would double up.
This is because the _cache in the channel threadsManager would use
the staged thread ID even after we'd replaced the object's ID with
the actual thread from the DB. The answer to this is to remove and
re-add the thread to the local cache with the actual ID.
* DEV: Fix and re-enable chat flakys
The early return in JS was added to prevent an error
from channel being null, and it's better to use known
users for the message fabrications in the specs.
* DEV: Use travel_to in drawer spec for thread tracking
Sometimes in the system test the datetime that is last
viewed for the channel for the user and the datetime for
the last message created_at is only microseconds of difference,
and we do not provide that level of fidelity in the MessageBus
serializer, so unreadThreadsCountSinceLastViewed is not
accurate.
Better to just utilize travel_to and move forward 1 minute in
time before sending the new message to easily differentiate.
We need a nice way to only return some hashtag data
sources based on various site settings. This commit
adds an enabled? method that every hashtag data source
must implement. If this returns false the data source
will not be used at all for hashtag lookups or search.
This commit makes it so that when the user has unread threads
for a channel we show a blue dot in the sidebar (or channel index
for mobile/drawer).
This blue dot is slightly different from the channel unread messages:
1. It will only show if the new thread messages were created since
the user last viewed the channel
2. It will be cleared when the user views the channel, but the threads
are still considered unread because we want the user to click into
the thread list to view them
This necessitates a change to the current user serializer to also
include the unread thread overview, which is all unread threads
across all channels and their last reply date + time.
Why this change?
The test being changed in question has been flaky on our CI. However, we
are unable to view the screenshot of why it failed because
ActionDispatch will only take a screenshot of the default session upon

Rails APIs at the moment. Therefore, we're changing this system test to
avoid using two custom session and instead have the main assertion use
the default session such that any failures will provide us with a
screenshot.
Prior to this change you might end up in a loop where removing a channel would redirect you to this channel and as we auto-follow opened direct message channels, you could never unfollow this last direct message channel.
Followup to d7ef7b9c03,
this adds a spec to test the case where old threads are
still unread for the user and should show at the top regardless
of pagination, and fixes some issues/makes some slight refactors.
This commit attempts to fix an issue where we are ending
up with bad created_at date formats for last messages, which
is breaking the DM sort order and sometimes causing DM channels
to fall off the list, or show "Invalid date" on mobile.
I have not been able to consistently reproduce these issues
locally, however the serialzier for the channels index uses
MultiJSON.dump() and the Chat::Publisher uses .to_json, both of
which format created_at differently for messages.
The former is `2023-07-05T06:53:25.977Z` (iso8601).
The latter is `2023-07-14 03:59:22 UTC` (.to_s default).
Since we are doing comparison and sorting of these dates on the UI
we need consistent formatting for the JS Date parsers (and moment)
to deal with.
If the issue still occurs after this we can investigate further.
It could only occur on message created by the user itself and deleted while the user was looking at the channel.
It more generally fix the trash service which was not correctly setting the author of the delete.
`SiteSetting.enable_public_channels` allows site admin to decide if public channels are available at all. There's no distinction between admins or not as we expect admins to create private category channels if they want to limit usage.
Not sure how this was even working previously, since it's trying
to press the reply button on a thread original message, which doesn't
work, you need to click the indicator to open the thread.
Why this change?
The following test is flaky on our CI:
```
1) Navigation when sidebar is configured as the navigation menu when re-opening full page chat after navigating to a channel opens full page chat on correct channel
Failure/Error: measurement = Benchmark.measure { example.run }
expected "/" to equal "/chat/c/random-9/17"
```
The theory here is that system tests is running too fast that we're not
giving the href for the chat header icon a chance to update before
clicking on it. Therefore, we're adding an additional assertion to
assert that the link has the right href before clicking on it.
Initial migration and changes to models as well as
changing the following services to update last_message_id:
* Chat::MessageCreator
* Chat::RestoreMessage
* Chat::TrashMessage
The data migration will set the `last_message_id` for all existing
threads and channels in the database.
When we query the thread list as well as the channel,
we look at the last message ID for the following:
* Channel - Sorting DM channels, and channel metadata for the list of channels
* Thread - Last reply details for thread indicators and thread list
It is now safe to render the message excerpt as HTML since
it is no longer using text_entities: true in the server
PrettyText.excerpt call when creating the message excerpt
from the cooked HTML.
This will fix the issue of things like mentions showing
HTML code instead of the actual mention when replying,
and cannot be used to inject improper HTML like style tags
via XSS.
This commit makes sure we don't load all data into memory when doing CSV exports.
The most important change here made to the recently introduced export of chat
messages (3ea31f4). We were loading all data into memory in the first version, with
this commit it's not the case anymore.
Speaking of old exports. Some of them already use find_each, and it worked as
expected, without loading all data into memory. And it will proceed working as
expected after this commit.
In general, I made sure this change didn't break other CSV exports, first manually, and
then by writing system specs for them. Sadly, I haven't managed yet to make those
specs stable, they work fine locally, but flaky in GitHub actions, so I've disabled them
for now.
I'll be making more changes to the CSV exports code soon, those system specs will be
very helpful. I'll be running them locally, and I hope I'll manage to make them stable
while doing that work.
This implementation will need more work in the future. For simplification of tracking and other events (new thread, delete/restore OM...) we used the threads from `threadsManager` which makes pagination more complicated as we already have some results when we start.
Note this commit also simplify `Collection` to only have one `load` method which can be called repeatedly.
Why this change?
The specs are flaky on CI and we've unable to figure out why so we've
decided to skip them only on CI for now. The tests are still ran in our
internal build so we still have some protection in place.
Why is this change being made?
We've decided that the previous "community" section should look more
like a primary section that holds the most important navigation links
for the site and the word "community" doesn't quite fit that
description. Therefore, we've made the decision to drop the
section heading for the community section.
As part of removing the section heading, the following changes are made
as well:
1. Button to customize the section has been moved to the "footer" of the
"More..." section when `navigation_menu` site setting is set to `sidebar`.
When `navigation_menu` is set to `header dropdown`, a button to customize
the section is shown inline.
2. The section will no longer be collapsable.
3. The title of the section is no longer customisable as it is no longer
displayed. As a technical note, we have not dropped any previous
customisations of the section's title previously in case we have to
bring back the header in the future.
4. The new topic button that was previously present in the header has
been removed alongside the header. Admins can add a custom section
link to the `/new-topic` route if there would like to make it easier for
users to create a new topic in the sidebar.
The `message_bus_channels` given to `MessageBus.last_ids(*message_bus_channels)` is not ordered, as a result the expectation of the tests could fail, this test ensures we check the contain of the input instead of content+order.
This commit also standardize the naming pattern of modals: `<Chat::Modal::FooBar />` and changes css class accordingly.

When the loading slider is enabled, the rendering of `application.hbs` is slightly delayed compared to the old 'spinner' strategy. This means that if a route tried to render a dialog during its `model()` hook, the dialog wrapper element would not be present and an error would occur.
This commit detects that situation and delays rendering the error until the next runloop iteration. If the element is still not found, we print a useful error to the console.
In the long term, we should ideally convert the dialog service to use a pure-ember rendering strategy instead of leaning on a11y-dialog. But for now, this workaround should resolve the problems identified by the chat system specs.
It's way more common to have presence enabled than disabled, so we should have been making it the default from start.
This commit also changes the namespace of `<ChatUserAvatar />` into `<Chat::UserAvatar />` and refactors tests.
When a user sends their first message in a thread we
automatically track the thread in the backend, but we
don't reflect this in the UI until the user re-opens
the thread. This commit fixes that by showing the new
tracking level in the UI.
Chat drawer was using the `DiscourseURL` hook `afterRouteComplete`. This hook suffer from a very poor implementation which makes it very unreliable:
```javascript
if (typeof opts.afterRouteComplete === "function") {
schedule("afterRender", opts.afterRouteComplete);
}
```
This commit attempts to return the promise from `handleURL` to directly use it and have a very reliable after transition hook.
In previous changes we prevented creating a channel to also make users follow the channel. We were forcing recipients to follow the channel on message sent but this was not including the creator of the message itself.
This commit fixes it and also write an end-to-end system spec to cover these cases. The message creator service is currently being rewritten and should correctly test and ensure this logic is present.
This commit also makes changes on the frontend to instantly follow a DM when you open it, this change prevents a green dot to appear for a split second when you send a message in a channel you were previously not following. Only recipients will see the green dot.
Since we create threads in the background regardless of whether
threading is enabled for a channel, we get the unexpected behaviour
of everyone having a lot of unread threads when threading is enabled
for the channel.
To counteract this, when the admin enables threads for a channel
we can just run a high priority background job to mark all threads
as read in the channel for all users, so they are essentially
starting from a clean slate.

We should not hide the replies count if there is only 1 participant
for a thread, because this makes it look like the last reply is the
only reply.
This introduces a PLATFORM_KEY_MODIFIER const that
can be used both client and server side, to determine
whether we should be using the Meta or Ctrl key based
on whether the user is on Windows/Linux or Mac.
Why this change?
`Faker::Lorem.paragraph` generates a differrent length of string
every time. When a string happens to be long, it can change the UI
across system test runs making it harder to reason about our system
tests across multiple runs since the state is never really consistent.
We will just generate a paragraph with a fixed length going forward so
that the UI remains consistent. This should make certain tests which
relies on the UI being in a certain state to become less flaky.
Why this change?
This change ensures that we scroll to the top of the message when
hovering over a message to ensure that the message actions container
that appears on hover is not hidden in the chat drawer when the content
of the chat message is long.
