When we were deleting messages in chat, we would find all of
the UserChatChannelMembership records that had a matching
last_read_message_id and set that column to NULL.
This became an issue when multiple users had that deleted message
set to their last_read_message_id. When we called ChannelUnreadsQuery
to get the unread count for each of the user's channels, we were
COALESCing the last_read_message_id and returning 0 if it was NULL,
which meant that the unread count for the channel would be the total
count of the messages not sent by the user in that channel.
This was particularly noticeable for DM channels since we show
the count with the indicator in the header. This issue would disappear
as soon as the user opened the problem channel, because we would then
set the last_read_message_id to an actual ID.
To circumvent this, instead of NULLifying the last_read_message_id in
most cases, it makes more sense to just set it to the most recent
non-deleted chat message ID for the channel. The only time it will
be set to NULL now is when there are no more other messages in the
channel.
We need to create and update `chat_mentions` records for messages earlier. They should be created or updated before we call `Chat::Publisher.publish_new!` `Chat::Publisher.publish_edit!` to send the message to message bus subscribers).
This logic is covered with tests in `message_creator_spec.rb`, `message_updater_spec.rb`, `notifier_spec.rb` and `notify_mentioned_spec.rb`.
See the commits history for steps of refactoring.
Since our recent change of inverting thread scrolling direction it feels more responsive to scroll down in thread panel as soon as message is staged and not after it's actually persisted.
When hovering a thread indicator in a channel we will now append two `<link rel="preload" ...>` to the `<head>` of the document. Clicking on it should be significantly faster.

This commit implements all the necessary logic to create thread seamlessly. For this it relies on the same logic used for messages and generates a `staged-id`(using the format: `staged-thread-CHANNEL_ID-MESSAGE_ID` which is used to re-conciliate state client sides once the thread has been persisted on the backend.
Part of this change the client side is now always using real thread and channel objects instead of sometimes relying on a flat `threadId` or `channelId`.
This PR also brings three UX changes:
- thread starts from top
- number of buttons on message actions is dependent of the width of the enclosing container
- <kbd>shift + ArrowUp</kbd> will reply to the last message
See e323628d8a for more details.
This commit speeds up the tests by roughly 10 seconds locally where the
default wait time is 2 seconds. On CI, this speeds up the tests by 20
seconds where the default wait time is 4 seconds.
* FIX: Link to thread for mentions inside thread
When mentioning a user in a thread, when we send the
notification and display it in the UI we want the URL
of the notification to point to the thread URL to open
the panel, rather than the main channel which is confusing.
For now, we don't have a way to highlight the linked-to message
in the thread, we can revisit this later.
* FIX: Mark mention notifications read when thread opens
Since we have no scrolling/message visibility/thread membership
for now, when a user opens the thread panel we just want to mark
all mention notifications relating to messages in the thread
for the user as read.
In the past this was happening on scroll so we needed to be very conservative here. Also, if we wait too much theres a visible element flashing so this PR attempts to compute right away, and a second time 100ms later in case the first one happened too early.
It seems more reliable to revert state at the end of the it block. In another PR I noticed that the network state was leaking in other tests when I was reverting in the after block.
Also trashes a suspicious spec.
This will avoid the messages actions floating around while scrolling. Note it's not testing the thread counterpart yet as I have a plan in mind to tests channels and threads in a clean way in the near future.
Before this fix if the underlying model of a reviewable was changed, the filter wouldn't work anymore as it was expecting a 1:1 relation between filter type and model name.
This commit also relies on the `Reviewable.types` array to check against valid types instead of a regex not checking much.
Finally this commit adds a spec to ensure chat reviewables are listable from the review index page.
Prior to this fix uploads event could end up in the wrong textarea. This will most importantly allow pasting an image in the thread composer.
Also fixes a minor padding issue on thread when uploads are associated to it.
`.chat-channel` had `300px` min width, when `.chat-drawer` was `250px`, resulting in overflowing channel when in drawer. This commits ensures the limits are always set at `250px`.
- using BEM notation
- making animation linear instead of default ease
- small tweaks to composer state (disabled/send-disabled/send-enabled)
- fixing bug with disabled composer on mobile
- It seems that `window_opened_by/within_window` it not reliable in our current setup/test
- System specs should avoid at all cost to rely on backend state, any change should be visible one way or another on the front to be properly tested
1. `this.chat.activeChannel = null` was being done in twice
2. using `willTransition()` and checking transition.to.name prefix for route cleanup rather than using `deactivate()` was unnecessarily verbose and could be premature (if something aborted the transition you'd end up in a broken state)
3. `activeChannel` on Chat service can be null, check for that before accessing
It's very hard to repro but under specific circumstances I suspect it was possible for this sequence to happen:
- set message TEXT
- cooking starts
- set message COOKED through another mean (like a message bus)
- the cooking started sooner finished and erases the cooked set at the step before causing the message to have the incorrect cooked
After removing `TextareaTextManipulation` from `ChatComposer` and using `TextareaInteractor` as a proxy, one function has been forgotten: `paste(event)` which is not available in glimmer components anymore, and even less avaiable now that the mixin is not tied to a component anymore but a real DOM node. As a solution we now add a manual paste event listener which will call `paste(event)`.
This pull request is a full overhaul of the chat-composer and contains various improvements to the thread panel. They have been grouped in the same PR as lots of improvements/fixes to the thread panel needed an improved composer. This is meant as a first step.
### New features included in this PR
- A resizable side panel
- A clear dropzone area for uploads
- A simplified design for image uploads, this is only a first step towards more redesign of this area in the future
### Notable fixes in this PR
- Correct placeholder in thread panel
- Allows to edit the last message of a thread with arrow up
- Correctly focus composer when replying to a message
- The reply indicator is added instantly in the channel when starting a thread
- Prevents a large variety of bug where the composer could bug and prevent sending message or would clear your input while it has content
### Technical notes
To achieve this PR, three important changes have been made:
- `<ChatComposer>` has been fully rewritten and is now a glimmer component
- The chat composer now takes a `ChatMessage` as input which can directly be used in other operations, it simplifies a lot of logic as we are always working a with a `ChatMessage`
- `TextareaInteractor` has been created to wrap the existing `TextareaTextManipulation` mixin, it will make future migrations easier and allow us to have a less polluted `<ChatComposer>`
Note ".chat-live-pane" has been renamed ".chat-channel"
Design for upload dropzone is from @chapoi
- Move the old '`define_include_method`' arg to a `respect_plugin_enabled` kwarg
- Introduce an `include_condition` kwarg which can be passed a lambda with inclusion logic. Lambda will be run via `instance_exec` in the context of the serializer instance
This is backwards compatible - old-style invocations will trigger a deprecation message

Update chat and poll plugins to new pattern
Further followup to 24ec06ff85,
where I prevented other chat scheduled jobs from running if
chat was disabled. We should not be running any plugin scheduled
jobs if that plugin is disabled, it can cause unexpected
behaviour.
This was reverted in 38cebd3ed5.
The issue was that I was using Discourse.redis.delete_prefixed
which does a slow redis KEYS lookup, which is not advised in
production. This commit removes that, and also ensures the periodical
thread count update only happens if threading is enabled.
I changed to use a redis INCR/DECR for reply count
cache. This avoids a round trip to redis to GET the current
count, and also avoids multi-process issues, where
if there's two processes trying to increment at the
same time, they may both receive the same value, add one
to it, then both write the same value back.
Then, it's only n+1 instead of n+2.
This also prevents almost all chat scheduled jobs from
running if chat is disabled, the only one remaining is
the message retention job.
This commit moves the category channel creation out
of the Chat::Api::Channel controller and into a
dedicated CreateCategoryChannel service. A follow up
commit will move the DM channel creation out of
the old DirectMessageChannelCreator service.
Also includes a new on_model_errors helper
for chat service class usage, that collects model
validation errors to present in a nice way.

This adds these two new test cases:
context "when updating a mentioned user" do
it "updates the mention record" do
# and
context "when there are duplicate mentions" do
it "creates a single mention record per mention" do
Apart from that, this groups mention related tests into a context, renames one test, and moves setup of another test into the test case itself from the before block (to make it more clear, that test is the only one that uses that setup). See the PR's commit history.
Steps to reproduce the bug:
1. Send a chat message
2. Edit the message and add a mention to it
3. The mentioned user won't receive a notification
This PR fixes the problem.
Also:
1. There's no need anymore to have a code for removing notifications in the `notify_edit` method, because a call to `@chat_message.update_mentions` in the first line of the `notify_edit` method does that job:
ff56f403a2/plugins/chat/lib/chat/notifier.rb (L90)
2. There's no need to load mention records from database, it's enough to pluck user ids
Followup to bd5c5c4b5f, a
bug was introduced there for any channel that did not have
threading enabled or sites with the experimental threading
disabled. When the user replied to another chat message,
since this is always a thread in the background, we weren't
sending any MessageBus messages to the main channel, since
the message was a thread reply.
However in the UI these messages still show in the main stream
of the channel if threading is turned off, so the UI was not
reacting to these things happening in the backend. The worst
issue was that new clients would not see new replies sent in
reply to other messages in the channel.
