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.

Use `Chat::ChatChannelFetcher.secured_public_channel_search` directly
checking for existence instead of running through
`Chat::ChatChannelFetcher.secured_public_channels` which executes 7 more
DB queries.
Follow up to a review in #18937, this commit changes the HashtagAutocompleteService to no longer use class variables to register hashtag data sources or types in context priority order. This is to address multisite concerns, where one site could e.g. have chat disabled and another might not. The filtered plugin registers I added will not be included if the plugin is disabled.
In both ChatMessage#rebake! and in ChatMessageProcessor
when we were calling ChatMessage.cook we were missing the
user_id to cook with, which causes missed hashtag cooks
because of missing permissions.
Previously, restricted category chat channel was available for all groups - even `readonly`. From now on, only user who belong to group with `create_post` or `full` permissions can access that chat channel.
This introduces another "section" of queries to the
hashtag autocomplete search, which returns results for
each type that start with the search term. So now results
will be in this order, and within these sections ordered
by the types in priority order:
1. Exact matches sorted by type
2. "starts with" sorted by type
3. Everything else sorted by type then name within type
There is no need to duplicate check chat messages when they are being
edited but not having their message text changed. This was leading to
a validation error when adding/removing an upload but not changing the
message text.
FEATURE: Chat and Sidebar are now on by default
- Set the sidebar site setting to be enabled by default
- Set the chat site setting to be enabled by default
- Updated existing specs that assumed the original default
- Use a migration to keep old defaults for existing sites
Instead of passing `user` to `guardian.can_chat?`, we
can just use the inner `@user` that is part of the guardian
instance already to determine whether that user can chat,
since this is how it works for all other usages of guardian
even within chat.
1. "What Goes Up Must Come Down" – if you subscribe to message bus, make sure you also unsubscribe
2. When you unsubscribe - remove only your subscription, not **all** subscriptions on given channel
Attempt #2. The first attempt tried to extend a core `@bound` method in new-user-narrative plugin which did not work. I reworked that plugin in the meantime. This new PR also cleans up message bus subscriptions in now core-merged chat plugin.
We must set `treatAsTextarea` to true when using autocomplete
in the chat composer, since it is at the bottom of the screen
we always want to show it above the composer. This fixes the
issue where the hashtag autocomplete results went behind the
keyboard on mobile (which was not happening for mentions).
Previously with this experimental feature a user would be
able to search for public channels for public categories
using the new #hashtag system even if they couldn't chat.
This commit fixes the hole.
This commit allows us to type # in the UI and present autocomplete
results immediately with the following logic for the topic composer,
and reversed for the chat composer:
* Categories the user can access and has not muted sorted by `topic_count`
* Tags the user can access and has not muted sorted by `topic_count`
* Chat channels the user is a member of sorted by `messages_count`
So in effect, we allow searching for hashtags without a search term.
To do this we add a new `search_without_term` to each data source so
each one can define how it wants to handle this logic.
This new site setting replaces the
`enable_experimental_sidebar_hamburger` and `enable_sidebar` site
settings as the sidebar feature exits the experimental phase.
Note that we're replacing this without depreciation since the previous
site setting was considered experimental.
Internal Ref: /t/86563
* FEATURE: Enforce mention limits for chat messages
The first part of these changes adds a new setting called `max_mentions_per_chat_message`, which skips notifications when the message contains too many mentions. It also respects the `max_users_notified_per_group_mention` setting
and skips notifications if expanding a group mention would exceed it.
We also include a new component to display JIT warning for these limits to the user while composing a message.
* Simplify ignoring/muting filter in chat_notifier
* Post-send warnings for unsent warnings
* Improve pluralization
* Address review feedback
* Fix test
* Address second feedback round
* Third round of feedback

This commit adds the messages_count column for ChatChannel messages,
which is the number of not-deleted messages in the channel.
This is not updated every time a message is created or deleted in a
channel, so it should not be displayed in the UI.
It is updated eventually via Jobs::ChatPeriodicalUpdates, which
will have additional functions in future after being introduced
here.
Also update these counts for existing channels in a post migration.
User options were serialized at the root level of CurrentUserSerializer,
but UserSerializer has a user_option field. This inconsistency caused
issues in the past because user_option fields had to be duplicated on
the frontend.
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.
