Prior to this change we would pre-load all the user channels which making initial page load slower. This change will make them be loaded right after initial load. In the past this was not possible as the channels would have to be loaded on each page transition. However since about a year, we made the channels to be cached on the frontend and no other request will be needed.
I have decided for now to not show a loading state in the sidebar as I think it would be noise, but we can reconsider this later.
Note given we don't have the channels loaded at first certain things where harder to accomplish. The biggest UX change of this commit is that we removed all the complex logic of computing the best channel to display when you load /chat. We will now store the id of the last channel you visited and will use this id to decide which channel to show.
Previously services would let you define a high level default `def default_actions_for_service; end` which would define various handlers like `on_success`, after months of usage we consider the cons are superior to the pros here.
Two mains cons:
- people would often not understand where the handling was coming from
- it's easy to miss a case when you write your specs
Forcing a thread will work even in channel which don't have `threading_enabled` or in direct message channels.
For now this feature is only available through the `ChatSDK`:
```ruby
ChatSDK::Message.create(in_reply_to_id: 1, guardian: guardian, raw: "foo bar baz", channel_id: 2, force_thread: true)
```
Prior to this fix we were checking if user was not part of a group which allows to chat, but we were not checking if this user was part of groups who can use direct messages.
When we send a bookmark reminder, there is an option to delete
the underlying bookmark. The Notification record stays around.
However, if you want to filter your notifications user menu
to only bookmark-based notifications, we were not showing unread
bookmark notifications for deleted bookmarks.
This commit fixes the issue _going forward_ by adding the
bookmarkable_id and bookmarkable_type to the Notification data,
so we can look up the underlying Post/Topic/Chat::Message
for a deleted bookmark and check user access in this way. Then,
it doesn't matter if the bookmark was deleted.
```ruby
ChatSDK::Message.start_stream(message_id: 1, guardian: guardian)
ChatSDK::Message.stream(raw: "foo", message_id: 1, guardian: guardian)
ChatSDK::Message.stream(raw: "bar", message_id: 1, guardian: guardian)
ChatSDK::Message.stop_stream(message_id: 1, guardian: guardian)
```
Generally speaking only admins or owners of the message can interact with a message. Also note, Streaming to an existing message with a different user won't change the initial user of the message.
This commit introduces the possibility to stream messages. To allow plugins to use streaming this commit also ships a `ChatSDK` library to allow to interact with few parts of discourse chat.
```ruby
ChatSDK::Message.create_with_stream(raw: "test") do |helper|
5.times do |i|
is_streaming = helper.stream(raw: "more #{i}")
next if !is_streaming
sleep 2
end
end
```
This commit also introduces all the frontend parts:
- messages can now be marked as streaming
- when streaming their content will be updated when a new content is appended
- a special UI will be showing (a blinking indicator)
- a cancel button allows the user to stop the streaming, when cancelled `helper.stream(...)` will return `false`, and the plugin can decide exit early
Affects the following settings:
delete_all_posts_and_topics_allowed_groups
experimental_new_new_view_groups
enable_experimental_admin_ui_groups
custom_summarization_allowed_groups
pm_tags_allowed_for_groups
chat_allowed_groups
direct_message_enabled_groups
chat_message_flag_allowed_groups
This turns off client: true for these group-based settings,
because there is no guarantee that the current user gets all
their group memberships serialized to the client. Better to check
server-side first.
The service `Chat::CreateMessage` will now accept `context_post_ids` and `context_topic_id` as params. These values represent the topic which might be visible when sending a message (for now, this is only possible when using the drawer).
The `DiscourseEvent` `chat_message_created` will now have the following signature:
```ruby
on(:chat_message_created) do | message, channel, user, meta|
p meta[:context][:post_ids]
end
```
This commit includes several changes to make hashtags work when "lazy
load categories" is enabled. The previous hashtag implementation use the
category colors CSS variables, but these are not defined when the site
setting is enabled because categories are no longer preloaded.
This commit implements two fundamental changes:
1. load colors together with the other hashtag information
2. load cooked hashtag data asynchronously
The first change is implemented by adding "colors" to the HashtagItem
model. It is a list because two colors are returned for subcategories:
the color of the parent category and subcategory.
The second change is implemented on the server-side in a new route
/hashtags/by-ids and on the client side by loading previously unseen
hashtags, generating the CSS on the fly and injecting it into the page.
There have been minimal changes outside of these two fundamental ones,
but a refactoring will be coming soon to reuse as much of the code
and maybe favor use of `style` rather than injecting CSS into the page,
which can lead to page rerenders and indefinite grow of the styles.
We usually don't enforce foreign key relationships on the database level.
Because of that, occasionally it's possible to see a chat message that
references to a non-existent chat_channel or user. MessagesExporter
failed in such case before, this PR fixes that.
At the moment, when someone is mentioning a group, or using here or
all mention, we create a chat_mention record per user. What we want
instead is to have special kinds of mentions, so we can create only one
chat_mention record in such cases. This PR implements that.
Note, that such mentions will still have N related notifications, one
notification per a user. We don't expect we'll have performance
problems on the notifications side, but if at some point we do, we
should be able to solve them on the side of notifications
(notifications are handled in jobs, also some little delays with
the notifications are acceptable, so we can make sure notifications
are properly queued, and that processing of every notification is
fast enough to make delays small enough).
The preparation work for this PR was done in fbd24fa, where we make
it possible for one mention to have several related notifications.
A pretty tricky part of this PR is schema and data migration, I've explained
related details inline on the migration files.
This adds the following chat metrics:
- _chat_open_channels_with_threads_enabled_ — a count of open channels
where threading is enabled.
- _chat_channel_messages_ — a count of messages sent in a chat channel
(i.e. not a personal chat / direct message), within a thread or outside of a thread.
- _chat_threaded_messages_ — a count of messages sent within a thread
in a chat channel (i.e. not a personal chat / direct messages).
- _chat_direct_messages_ — a count of messages sent in a personal chat / direct messages.
The metrics added using the plugin API introduced in 098ab29d,
and extended in d91456fd.
Note that these stats won't be exposed at the `about.json`
and the `site/statistics.json` routes.
This PR is a reworked version of https://github.com/discourse/discourse/pull/24670.
In chat, we need the ability to have several notifications per `chat_mention`.
Currently, we have one_to_one relationship between `chat_mentions` and `notifications`:
d7a09fb08d/plugins/chat/app/models/chat/mention.rb (L9)
We want to have one_to_many relationship. This PR implements that by introducing
a join table between `chat_mentions` and `notifications`.
The main motivation for this is that we want to solve some performance problems
with mentions that we're having now. Let's say a user sends a message with @ all
in a channel with 50 members, we do two things in this case at the moment:
- create 50 chat_mentions
- create 50 notifications
We don't want to change how notifications work in core, but we want to be more
efficient in chat, and create only 1 `chat_mention` which would link to 50 notifications.
Also note, that on the side of notifications, having a lot of notifications is not so
big problem, because notifications processing can be queued.
Apart from improving performance, this change will make the code design better.
Note that I've marked the old `chat_mention.notification_id` column as ignored, but
I'm not deleting it in this PR. We'll delete it later in https://github.com/discourse/discourse/pull/24800.
Introduces the concept of image thumbnails in chat, prior to this we uploaded and used full size chat images within channels and direct messages.
The following changes are covered:
- Post processing of image uploads to create the thumbnail within Chat::MessageProcessor
- Extract responsive image ratios into CookedProcessorMixin (used for creating upload variations)
- Add thumbnail to upload serializer from plugin.rb
- Convert chat upload template to glimmer component using .gjs format
- Use thumbnail image within chat upload component (stores full size img in orig-src data attribute)
- Old uploads which don't have thumbnails will fallback to full size images in channels/DMs
- Update Magnific lightbox to use full size image when clicked
- Update Glimmer lightbox to use full size image (enables zooming for chat images)
I took the wrong approach here, need to rethink.

There will soon be additional login_required checks
for Guardian, and the intent of many checks by automated
systems is better fulfilled by using BasicUser, which
simulates a logged in TL0 forum user, rather than an
anon user.
In some cases the use of anon still makes sense (e.g.
anonymous_cache), and in that case the more explicit
`Guardian.anon_user` is used
We're seeing some deprecation warnings in production. This is because we're passing a raw Ruby timestamp, which gets stringified implicitly when written to Redis. As per #15842, this conversion needs to be done explicitly.
This PR introduces thread support for channel archives. Now, threaded messages are rendered inside a `details` HTML tag in posts.
The transcript markdown rules now support two new attributes: `threadId` and `threadTitle`.
- If `threadId` is present, all nested `chat` tags are rendered inside the first one.
- `threadTitle` (optional) defines the summary content.
```
[chat threadId=19 ... ]
thread OM
[chat ... ]
thread reply
[/chat]
[/chat]
```
If threads are split across multiple posts when archiving, the range of messages in each part will be displayed alongside the thread title. For example: `(message 1 to 16 of 20)` and `(message 17 to 20 of 20)`.
Chat will now check for the state of `SiteSetting.private_email` when sending the summary, when enabled, the mail will not display user information, channel information other than the ID and no message information, only the count of messages.
Group channels will allow users to create channels with a name and invite people. It's possible to add people even after creation of the channel. Removing users is not yet possible but will be added in the near future.
Technically a group channel is `direct_message_channel` with a group attribute set to true on its direct message (chatable). This model might evolve in the future but offers much flexibility for now without having to rely on a complex migration.
The commit essentially consists of:
- a migration to set existing direct message channels with more than 2 users to a group
- a new message creator which allows to search, add members, and create groups
- a new `AddUsersToChannel` service
- a modified `SearchChatable` service
This adds the ability to collect stats without exposing them
among other stats via API.
The most important thing I wanted to achieve is to provide
an API where stats are not exposed by default, and a developer
has to explicitly specify that they should be
exposed (`expose_via_api: true`). Implementing an opposite
solution would be simpler, but that's less safe in terms of
potential security issues.
When working on this, I had to refactor the current solution.
I would go even further with the refactoring, but the next steps
seem to be going too far in changing the solution we have,
and that would also take more time. Two things that can be
improved in the future:
1. Data structures for holding stats can be further improved
2. Core stats are hard-coded in the About template (it's hard
to fix it without correcting data structures first, see point 1):
63a0700d45/app/views/about/index.html.erb (L61-L101)
The most significant refactorings are:
1. Introducing the `Stat` model
2. Aligning the way the core and the plugin stats' are registered
There is an edge case where the following occurs:
1. The user sets a bookmark reminder on a post/topic
2. The post/topic is changed to a PM before or after the reminder
fires, and the notification remains unread by the user
3. The user opens their bookmark reminder notification list
and they can still see the notification even though they cannot
access the topic anymore
There is a very low chance for information leaking here, since
the only thing that could be exposed is the topic title if it
changes to something sensitive.
This commit filters the bookmark unread notifications by using
the bookmarkable can_see? methods and also prevents sending
reminder notifications for bookmarks the user can no longer see.
This commit starts from a simple observation: cooking messages on the hot path can be slow. Especially with a lot of mentions.
To move cooking from the hot path, this commit has made the following changes:
- updating cooked, inserting mentions and notifying user of new mentions has been moved inside the `process_message` job. It happens right after the `Chat::MessageProcessor` run, which is where the cooking happens.
- the similar existing code in `rebake!` has also been moved to rely on the `process_message`job only
- refactored `create_mentions` and `update_mentions` into one single `upsert_mentions` which can be called invariably
- allows services to decide if their job is ran inline or later. It avoids to need to know you have to use `Jobs.run_immediately!` in this case, in tests it will be inline per default
- made various frontend changes to make the chat-channel component lifecycle clearer. we had to handle `did-update @channel` which was super awkward and creating bugs with listeners which the changes of the PR made clear in failing specs
- adds a new `-processed` (and `-not-processed`) class on the chat message, this is made to have a good lifecyle hook in system specs
This is a follow-up to e6299a3. I additionally fixed these three things:
1. Since e6299a3 there's no need anymore to join the group_users table
when looking for users who were reached by a group mention, so
I removed that join in that commit. But turned out we were joining
the group_users table twice, so I removed the second join in this PR.
That drastically speeded up my test query, from 6 sec to 0.26 sec.
2. We also were joining twice the user_chat_channel_memebership table,
so I removed the second unnecessary join too.
3. We actually need to join the user_chat_channel_memebership table
only in certain cases, and we don't need to do that for group mentions,
so I fixed that too.
As a result of these changes, time of my test query fall down from
6 sec to 0.001 sec. And the resulting SQL query now contains only
one JOIN statement.
A follow-up to faac6773. This PR eliminates one more heavy join by forcing
Active Record to do two queries instead.
Also, along the way, I made this change:
```
# this generates two quries to the groups table
def groups_to_mention
@groups_to_mention = mentionable_groups - groups_with_too_many_members
end
# so I changed it to (this makes only one query to the groups table):
def groups_to_mention
@groups_to_mention ||= mentionable_groups.where("user_count <= ?", SiteSetting.max_users_notified_per_group_mention)
end
```
This one is kind of a premature optimization, because we don't have evidence that
this extra query is a problem, but it seems cleaner this way.
Commits history on this PR may help better understand the change.
Add new chat indicator preference within chat user preferences.
Enabling this option will mean that green notifications will only appear for mentions (within channels and DMs.
This change also enables mentions within direct messages.
This change allows users to edit their chat messages based on the criteria added to Site Settings.
If the grace period conditions are met then there will be no (edited) text applied to the message.
The following site settings are added to chat:
chat editing grace period (seconds since message created)
chat editing grace period max diff for low trust levels (number of characters changed)
chat editing grace period max diff for high trust levels (number of characters changed)
This feature adds notifications for chat messages that are sent within personal chats (1:1 and personal group chats).
To prevent notification spam we make use of consolidated notifications to combine updated message information in a meaningful way that allows the receiver to quickly jump into the chat to see what they missed.
This update respects muted channels, muted and blocked users. It will only create a new notification when the user has not muted the channel and the notified user is not muting or ignoring the message sender.
Currently, the logic for creating a new chat message is scattered
between a controller and an “old” service.
This patch address this issue by creating a new service (using the “new”
sevice object system) encapsulating all the necessary logic.
(authorization, publishing events, etc.)
- moves the onebox logic away from `plugin.rb` to a new `onebox_handler` lib
- splits the `discourse_chat_message` template into two: one for channels, and one for messages
- refactors the logic code slightly to send only the necessary arguments to each template
This commit shouldn't change end-user behavior.
This PR swaps out the custom pathway to publishing and rendering mention warnings after a message is sent.
ChatPublisher#publish_notice is used, and expanded. Now, instead of only accepting text_content as an argument, component and component_args are accepted and there is a renderer for these components.
Translations moved to server, as notices expect text to be passed in unless a component is rendered
The warnings are rendered at the top now, outside of the scope of the single message that sent it.
I entirely removed the jit_messages_spec b/c it's duplicate testing of other parts of the app. IMO we don't need a backend test for a feature, a component test for the feature AND a system test (that is slow and potentially even flakey due to timing issues with wait) to test the same thing. So jit_messages_spec is gone.
