We were attempting to fetch from last read but this is actually complicated to get right when you have a lot unread, as we might still have more to load after this but the last unread id is still the same and would make the user end up in a loop.
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.
Sharing a link in chat will create a onebox embed with a source that includes a site icon and title.
This change prevents loading the site icon into lightbox.

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.
Define new concept of panels in sidebar. Panels are wrappers around sidebar sections. In the future, it allows creating full focus mode by switching between panels.
A new API method called addSidebarPanel was added. Default main panel is already registered and by default all API sections are mounted to main.
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.
When we have subscriptions for new messages in a channel,
we also have special handling for messages in a thread. For
cases like DM channels where threads are made in the background
but not used in the UI, this is causing JS errors because we
are trying to fetch the thread but it returns 404.
We only want to do things with messages in threads if the
channel actually has threading enabled.
On tablets like iPad where we allow channel and thread to be on the same screen, it was not possible to resize the panels due to code being thought for mouse events. This commit should now correctly allow for this.
The "resizer" has also been made larger to simplify touching.
No test as it's hard to test on iPad and dragging events are also complex.
On iOS we have a hack to prevent the viewport to move when focusing an input, however this code was targeting the textarea node through a global selector which is working fine on iOS as we only show one composer at a time but was failing on iPad as we show both channel and thread on the same screen. As a result `document.querySelector(".chat-composer__input")` was always targeting the first textarea on the screen which was the channel's composer, making it impossible to focus the thread's one.
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.
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.
Prior to this commit a long press on the image of a chat message would trigger both the actions menu and the contextual menu. This commit ensures we only show the contextual menu in this case.
No test as it's a quite complex behavior to reproduce (would need android for example).
This was causing this event to cause other touch events down the road. For example click a reaction above the composer when the message action was opened could cause the composer to gain focus after the reaction was made.
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.
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.
* FEATURE: Inline topic summary. Cached version accessible to everyone.
Anons and non-members of the `custom_summarization_allowed_groups_map` groups can see cached summaries for any accessible topic. After the first 12 hours and if the posts to summarize have changed, allowed users clicking on the button will automatically re-generate it.
* Ensure chat summaries work and prevent model hallucinations when there are no messages.
Browser capabilities are inherently unconnected to the lifecycle of our app. Making them formally available outside of the service means that they can safely be used in non-app-linked functions without needing risky hacks like `helperContext()` or `discourse-common/lib/get-owner`.
One example of where the old hacks were problematic is the `translateModKey()` utility function. This is called in the root of the `discourse/components/modal/keyboard-shortcuts-help` es6 module. If anything (e.g. a theme/plugin) caused that es6 module to be `require()`d before the application was booted, a fatal error would occur.
Following this commit, `translateModKey()` can safely import and access `capabilities` without needing to worry about the app lifecycle.
The only potential downside to this approach is that the capabilities data now persists across tests. If any tests need to 'stub' capabilities, they will need to revert their changes at the end of the test (e.g. by using Sinon to stub a property).
This commit also updates some legacy references from `capabilities:main` to `service:capabilities`.
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.
Trying to fix two issues:
1. Sometimes the publish_new! event for update_thread_original_message
finishes running on the UI before the one for thread_created, in this
case we just want to do nothing because thread_created will fetch the
new thread along with its preview from the server if needed
2. Sometimes the thread GET and /read events were erroring because
last_reply on the thread was nil, this was potentially occuring because
the thread_created event was coming through to the UI before the rest
of MessageCreator was done, so we just move that after the big update
to set thread_id for the new and existing messages in the reply
chain
