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
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
This commit removes the ability to enable/disable the Sidebar on a per
user basis and introduces a site wide setting. For testing purposes, sidebar can be enabled/disabled via the `enable_sidebar=1` or `enable_sidebar=0` query param.
Before, whispers were only available for staff members.
Config has been changed to allow to configure privileged groups with access to whispers. Post migration was added to move from the old setting into the new one.
I considered having a boolean column `whisperer` on user model similar to `admin/moderator` for performance reason. Finally, I decided to keep looking for groups as queries are only done for current user and didn't notice any N+1 queries.
This commit fixes two issues at play. The first was introduced
in f6c852b (or maybe not introduced
but rather revealed). When a user posted a new message in a topic,
they received the unread topic tracking state MessageBus message,
and the Unread (X) indicator was incremented by one, because with the
aforementioned perf commit we "guess" the correct last read post
for the user, because we no longer calculate individual users' read
status there. This meant that every time a user posted in a topic
they tracked, the unread indicator was incremented. To get around
this, we can just exclude the user who created the post from the
target users of the unread state message.
The second issue was related to the private message topic tracking
state, and was somewhat similar. Whenever a user created a new private
message, the New (X) indicator was incremented, and could not be
cleared until the page was refreshed. To solve this, we just don't
update the topic state for the user when the new_topic tracking state
message comes through if the user who created the topic is the
same as the current user.
cf. https://meta.discourse.org/t/bottom-of-topic-shows-there-is-1-unread-remaining-when-there-are-actually-0-unread-topics-remaining/220817
It's very easy to forget to add `require 'rails_helper'` at the top of every core/plugin spec file, and omissions can cause some very confusing/sporadic errors.
By setting this flag in `.rspec`, we can remove the need for `require 'rails_helper'` entirely.
Previously we were publishing one messagebus message per user which was 'tracking' a topic. On large sites, this can easily be 1000+ messages. The important information in the message is common between all users, so we can manage with a single message on a shared channel, which will be much more efficient.
For user-specific values (notification_level and last_read_post_number), the JS app can infer values which are 'good enough'. Correct values will be loaded as soon as a topic-list containing the topic is visited.
There are certain design decisions that were made in this commit.
Private messages implements its own version of topic tracking state because there are significant differences between regular and private_message topics. Regular topics have to track categories and tags while private messages do not. It is much easier to design the new topic tracking state if we maintain two different classes, instead of trying to mash this two worlds together.
One MessageBus channel per user and one MessageBus channel per group. This allows each user and each group to have their own channel backlog instead of having one global channel which requires the client to filter away unrelated messages.
This is a try to simplify logic around dismiss new topics to have one solution to work in all places - dismiss all-new, dismiss new in a specific category or even in a specific tag.
Sometime parallel spec if failing with error:
```
NoMethodError:
undefined method `data' for nil:NilClass
# ./spec/models/topic_tracking_state_spec.rb:339:in `block (4 levels) in <main>'
```
I have a theory that it might be related to instance variables in before block
We previously did not account for completely untagged topics when
looking at muted tags, this caused new/unread counts to be off if
1. You had muted tags
2. You had an unread/new topic
3. This topic had no tags
This feature allows certain plugins to output tag information
to topic tracking state, this allows per tag stats which can be
used by sidebars and other plugins that need per tag stats
Not enabled by default cause this would add cost to a critical
query
Recently, we added feature that we are sending `/muted` to users who muted specific topic just before `/latest` so the client knows to ignore those messages - https://github.com/discourse/discourse/pull/9482
Same `/muted` message should be included when the post is edited
* FEATURE: don't display new/unread notification for muted topics
Currently, even if user mute topic, when a new reply to that topic arrives, the user will get "See 1 new or updated topic" message. After clicking on that link, nothing is visible (because the topic is muted)
To solve that problem, we will send background message to all users who recently muted that topic that update is coming and they can ignore the next message about that topic.
6e1fe22 introduced the possiblity for category_users to have a NULL notification_level, so that we can store `last_seen_at` dates without locking the notification level. At the time, this did not affect the topic-tracking-state query. However, the query changes in f434de2 introduced a slight change in behavior.
Previously, a subquery would look for a category_user with notification_level=mute. f434de2 refactored this to remove the subquery, and inverted some of the logic to suit.
The new query checked for `notification_level <> :muted`. If `notification_level` is NULL, this comparison will return NULL. In this scenario, notification_level=NULL means that we should fall back to the default tracking level (regular), and so we want the expression to resolve as true, not false. There was already a check for the existence of the category_users row, but it did not check for the existence of a NOT NULL notification_level.
This commit amends the expression so that the notification_level will only be compared if it is non-null.
When the tag is muted and topic contains that tag, we should not mark that message as NEW.
There are 3 possible settings which site admin can set.
remove_muted_tags_from_latest - always
It means that if the topic got at least one muted tag, we should not mark that topic as NEW
remove_muted_tags_from_latest - only muted
Similar to above, however, if at least one tag is not muted, the topic is marked as NEW
remove_muted_tags_from_latest - never
Basically, mute tag setting is ignored and all topics are set as NEW
* The read indicator now shows up when no member has read the last post of the topic (written by a non-member)
* The read indicator works on mobile and receives live updates from message bus
* The icon we display in the topic list was changed
* Added a title to the indicator to indicate its purpose when hovering over it
* Revert "Revert "FEATURE: Publish read state on group messages. (#7989) [Undo revert] (#8024)""
This reverts commit 36425eb9f0.
* Fix: Show who read only if the attribute is enabled
* PERF: Precalculate the last post readed by a group member
* Use book-reader icon instear of far-eye
* FIX: update topic groups correctly
* DEV: Tidy up read indicator update on write
* Reenable: "FEATURE: Publish read state on group messages. (#7989)"
This reverts commit 67f5cc1ce8.
* FIX: Read indicator only appears when the group setting is enabled
* Enable or disable read state based on group attribute
* When read state needs to be published, the minimum unread count is calculated in the topic query. This way, we can know if someone reads the last post
* The option can be enabled/disabled from the UI
* The read indicator will live-updated using message bus
* Show read indicator on every post
* The read indicator now shows read count and can be expanded to see user avatars
* Read count gets updated everytime someone reads a message
* Simplify topic-list read indicator logic
* Unsubscribe from message bus on willDestroyElement, removed unnecesarry values from post-menu, and added a comment to explain where does minimum_unread_count comes from
* Introduced fab!, a helper that creates database state for a group
It's almost identical to let_it_be, except:
1. It creates a new object for each test by default,
2. You can disable it using PREFABRICATION=0
This change both speeds up specs (less strings to allocate) and helps catch
cases where methods in Discourse are mutating inputs.
Overall we will be migrating everything to use #frozen_string_literal: true
it will take a while, but this is the first and safest move in this direction
