This PR is introducing glimmer usage in the chat-live-pane, for components but also for models. RestModel usage has been dropped in favor of native classes.
Other changes/additions in this PR:
- sticky dates, scrolling will now keep the date separator of the current section at the top of the screen
- better unread management, marking a channel as unread will correctly mark the correct message and not mark the whole channel as read. Tracking state will also now correctly return unread count and unread mentions.
- adds an animation on bottom arrow
- better scrolling behavior, we should now always correctly keep the scroll position while loading more
- reactions are now more reactive, and will update their tooltip without needed to close/reopen it
- skeleton has been improved with placeholder images and reactions
- when making a reaction on the desktop message actions, the menu won't move anymore
- simplify logic and stop maintaining a list of unloaded messages

* DEV: Remove linting of `one` key in MessageFormat string, it doesn't work
* REFACTOR: Fix misuse of pluralized string
This also ensures that the URL works on subfolder and shows the site setting link only for admins instead of staff. The string is quite complicated, so the best option was to switch to MessageFormat.

This also ensures that maximum 5 usernames are shown and fixes the number of "others" which was off by 1 if the current user reacted on a message.

Previous commit 479c0a3051 was done with the assumption that this info was defined on user serializer but it was actually defined on post serializer in core. This commit extends the user serializer for messages to add this data to the user.
Also correctly adds serializer test to ensure we actually have this data.
This commit 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**
* 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.
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.
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.
The settings tab of each category channel should now present the option to allow or disallow channel wide mentions: @here and @all.
When disallowed, using these mentions in the channel should have no effect.
This commit adds variousMessageBus.last_ids to serializer payloads
for chat channels and the chat view (for chat live pane) so
we can use those IDs when subscribing to MessageBus channels
from chat.
This allows us to ensure that any messages created between the
server being hit and the UI loaded and subscribing end up being
delivered to the client, rather than just silently dropped.
This commit also fixes an issue where we were subscribing to
the new-messages and new-mentions MessageBus channels multiple
times when following/unfollowing a channel multiple times.
This commit automatically ensures that category channels
have slugs when they are created or updated based on the
channel name, category name, or existing slug. The behaviour
has been copied from the Category model.
We also include a backfill here with a simplified version
of Slug.for with deduplication to fill the slugs for already
created Category chat channels.
The channel slug is also now used for chat notifications,
and for the UI and navigation for chat. `slugifyChannel`
is still used, but now does the following fallback:
* Uses channel.slug if it is present
* Uses channel.escapedTitle if it is present
* Uses channel.title if it is present
In future we may want to remove this altogether
and always rely on the slug being present, but this
is currently not possible because we are not generating
slugs for DM channels at this point.
This is a followup of the previous refactor where we created two new
models to handle all the dedicated logic that was present in the
`ChatChannel` model.
For the sake of consistency, `DMChannel` has been renamed to
`DirectMessageChannel` and the previous `DirectMessageChannel` model is
now named `DirectMessage`. This should help reasoning about direct
messages.
