What is the problem?
When an admin changes the default_sidebar_categories or default_sidebar_tags site settings and opts to backfill the setting,
we currently enqueue a sidekiq job to run the backfilling operation. When an admin changes those settings multiple times
within a short time frame, multiple sidekiq jobs with different backfilling parameters will be enqueued.
This is problematic if multiple jobs are executed concurrently as it may lead to situations where a job
with “outdated” site setting values is completed after a job with the “latest” site setting values.
What is the fix?
By setting `cluster_concurrency` to `1`, we ensure that only one of such
backfilling job will execute across all the sidekiq processes that are
deployed at any point in time. Since Sidekiq pops off job in the order
in which they are pushed, limiting the cluster concurrency here will
allow us to execute the enqueued `Jobs::BackfillSidebarSiteSettings`
jobs serially.
While we are unable to support OAUTH2 with pop3 (due to upstream dependency ruby/net-pop#16), we are adding the support for mail pollers plugin. Doing so, it would be possible to write a plugin which then uses other ways (microsoft graph sdk for example) to poll emails from a mailbox.
The idea is that a plugin would define a class which inherits from Email::Poller and defines a poll_mailbox static method which returns an array of strings. Then the plugin could call register_mail_poller(<class_name>) to have it registered. All the configuration (oauth2 tokens, email, etc) could be managed by sitesettings defined in the plugin.
This change adds support retroactively updating display names in the new quote format when the user's name is changed. It happens through a background job that is triggered by a callback when a user is saved with a new name.
https://meta.discourse.org/t/markdown-preview-and-result-differ/263878
The result of this markdown had different results in the composer preview and the post. This is solved by updating Loofah to the latest version and using html5 fragments like our user had reported. While the change was only needed in cooked_post_processor.rb for this fix, other areas also had to be updated due to various side effects.
When we introduced the new quote format with full-name display name:
```
[quote="Ted Johansson, post:1, topic:2, username:ted"]
we overlooked the code responsible for rewriting quotes when a user's name is changed.
```
The functional part of this change adds support for the new quote format in the code that updates quotes when a user's username changes. See the test case in `spec/services/username_changer_spec.rb` for the details.
In addition, this change adds a regression test for PrettyText to cover the new quote format, and extracts the code responsible for rewriting raw and cooked quotes into its own `QuoteRewriter` class. The functionality of the latter is tested through the tests in `spec/services/username_changer_spec.rb`.
Anonymization is among the most expensive operations we can perform with
extreme potential to impact the database. To mitigate risk we only allow a
single anonymization across the entire cluster concurrently.
This commit introduces support for `cluster_concurrency 1`. When you set that on a Job it will only allow 1 concurrent execution per cluster.
On the client-side, message-bus subscriptions and reviewable count UI is based on the 'redesigned_user_menu_enabled' boolean. We need to use the same logic on the server-side to ensure things work correctly when legacy navigation is used alongside the new user menu.
2e78045a fixed the anonymization job so that it correctly updated self-mentions, which are not logged in the post_actions table. The solution was to scan the entire `posts` table with an `raw ILIKE` query. On sites with many posts, this can take a very long time.
This commit updates the job to take a two-pass approach:
First, we update posts based on the post_actions table. This is much more efficient than a full table scan, and takes care of all 'non-self' mentions.
Then, we make a second pass using the `raw ILIKE` approach. Since we already took care of most posts, we can scope this down to self-mentions only. By filtering the query to a specific posts.user_id, it is significantly more performant than a full table scan.
Currently, we’re performing a check when a user is suspended in the
`UserEmail` job and we’re assuming a `post` is always available, which
is not the case. The code indeed breaks when the job is called with the
`account_suspended` type option.
This patch fixes this issue by making the check use the safe navigation
operator, thus making it working when `post` is not provided.
Currently, when a suspended user belongs to a group PM (private message
with more than two people in it) and a staff member sends a message to
this group PM, then the suspended user will receive an email.
This happens because a suspended user can only receive emails from staff
members. But in this case, this can be seen as a bug as the expected
behavior would be instead to not send any email to the suspended user. A
staff member can participate in active discussions like any other
member and so their messages in this context shouldn’t be treated
differently than the ones from regular users.
This patch addresses this issue by checking if a suspended user receives
a message from a group PM or not. If that’s the case then an email won’t
be sent no matter if the post originated from a staff member or not.

Forcing distributed muted to raise when a notify reviewable job is running
leads to excessive errors in the logs under many conditions.
The new pattern
1. Optimises the counting of reviewables so it is a lot faster
2. Holds the distributed lock for 2 minutes (max)
The downside is the job queue can get blocked up when tons of notify
reviewables are running at the same time. However this should be very
rare in the real world, as we only notify when stuff is flagged which
is fairly infrequent.
This also give a fair bit more time for the notifications which may be
a little slow on large sites with tons of mods.
The #pluck_first freedom patch, first introduced by @danielwaterworth has served us well, and is used widely throughout both core and plugins. It seems to have been a common enough use case that Rails 6 introduced it's own method #pick with the exact same implementation. This allows us to retire the freedom patch and switch over to the built-in ActiveRecord method.
There is no replacement for #pluck_first!, but a quick search shows we are using this in a very limited capacity, and in some cases incorrectly (by assuming a nil return rather than an exception), which can quite easily be replaced with #pick plus some extra handling.
Posts with self-mentions aren't updated with username updates. This happens
because mention `UserAction` entries aren't logged for self-mentions.
This change updates the lookup of `Post` and `PostRevision` with mentions to bypass
`UserAction` entries.
Under scenarios of extremely high load where large numbers of `Reviewable*` items are being created, it has been observed that multiple instances of the `NotifyReviewable` job may run simultaneously.
These jobs will work satisfactorily if the concurrency is limited to 1, and the different types of jobs (items reviewable by admins, vs moderators, vs particular groups, etc.) are run eventually.
This change introduces a new option to `DistributedMutex` which allows the `max_get_lock_attempts` to be specified. If the number is exceeded an error will be raised, which will cause Sidekiq to requeue the job. Sidekiq has existing logic to back-off on retry times for jobs that have failed multiple times.
So it can easily be overwritten in a plugin for example.
### Added more tests to provide better coverage
We previously only had `u.silenced_till IS NULL` but I made it consistent with pretty much every other places where we check for "active" users.
These two new lines do change the query a tiny bit though.
**Before**
- You could not get the badge if you were currently silenced (no matter what period is being checked)
- You could get the badge if you were suspended 😬
**After**
- You can't get the badge if you were silenced during the past year
- You can't get the badge if you were suspended during the past year
### Improved the performance of the query by using `NOT EXISTS` instead of `LEFT JOIN / COUNT() = 0`
There is no difference in behaviour between
```sql
LEFT JOIN user_badges AS ub ON ub.user_id = u.id AND ...
[...]
HAVING COUNT(ub.*) = 0
```
and
```sql
NOT EXISTS (SELECT 1 FROM user_badges AS ub WHERE ub.user_id = u.id AND ...)
```
The only difference is performance-wise. The `NOT EXISTS` is 10-30% faster on very large databases (aka. posts and users in X millions). I checked on 3 of the largest datasets I could find.
```
class Jobs::DummyDelayedJob < Jobs::Base
def execute(args = {})
end
end
RSpec.describe "Jobs.run_immediately!" do
before { Jobs.run_immediately! }
it "explodes" do
current_user = Fabricate(:user)
Jobs.enqueue_in(1.seconds, :dummy_delayed_job)
sign_in(current_user)
end
end
```
The test above will fail with the following error if `ActiveRecord::Base.connection_handler.clear_active_connections!` is called before the configured Capybara server checks out a connection from the connection pool.
```
ActiveRecord::ActiveRecordError:
Cannot expire connection, it is owned by a different thread: #<Thread:0x00007f437391df58@puma srv tp 001 /home/tgxworld/.asdf/installs/ruby/3.1.3/lib/ruby/gems/3.1.0/gems/puma-6.0.2/lib/puma/thread_pool.rb:106 sleep_forever>. Current thread: #<Thread:0x00007f437d6cfc60 run>.
```
We're not exactly sure if this is an ActiveRecord bug or not but we've
invested too much time into investigating this problem. Fundamentally,
we also no longer understand why `ActiveRecord::Base.connection_handler.clear_active_connections!` is being called in an ensure block
within `Jobs::Base#perform` which was added in
ceddb6e0da 10 years ago. This
commit moves the logic for running jobs immediately out of the
`Jobs::Base#perform` method into another `Jobs::Base#perform_immediately` method such that
`ActiveRecord::Base.connection_handler.clear_active_connections!` is not
called. This change will only impact the test environment.
When sending emails out via group SMTP, if we
are sending them to non-staged users we want
to mask those emails with BCC, just so we don't
expose them to anyone we shouldn't. Staged users
are ones that have likely only interacted with
support via email, and will likely include other
people who were CC'd on the original email to the
group.

* DEV: Skip push notifications for active online users
Currently, users with active push subscriptions get push notifications
regardless of their "presence" on the site.
This change introduces a `push_notification_time_window_mins`
site setting which is used in conjunction with a user's `last_seen_at` to
determine if push notifications should be sent. A user is considered to
be actively online if their `last_seen_at` is within `push_notification_time_window_mins`
minutes. `push_notification_time_window_mins` is set to 10 by default.
* DEV: Remove client param for push_notification_time_window_mins site setting

This commit adds a new notification that gets sent to admins when the site gets new features after an upgrade/deploy. Clicking on the notification takes the admin to the admin dashboard at `/admin` where they can see the new features under the "New Features" section.
Internal topic: t/87166.
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
Users who can access the review queue can claim a pending reviewable(s) which means that the claimed reviewable(s) can only be handled by the user who claimed it. Currently, we show claimed reviewables in the user menu, but this can be annoying for other reviewers because they can't do anything about a reviewable claimed by someone. So this PR makes sure that we only show in the user menu reviewables that are claimed by nobody or claimed by the current user.
Internal topic: t/77235.
While load testing our user creation code path in production, we
identified that executing the DB statement to update the `Group#user_count` column within a
transaction is creating a bottleneck for us. This is because the
creation of a user and addition of the user to the relevant groups are
done in a transaction. When we execute the DB statement to update
`Group#user_count` for the relevant group, a row level lock is held
until the transaction completes. This row level lock acts like a global
lock when the server is creating users that will be added to the same
group in quick succession.
Instead of updating the counter cache within a transaction which the
default ActiveRecord `counter_cache` option does, we simply update the
counter cache outside of the committing transaction.

The previous sidebar default tags and categories implementation did not
allow for a user to configure their sidebar to have no categories or
tags. This commit changes how the defaults are applied. When a user is being created,
we create the SidebarSectionLink records based on the `default_sidebar_categories` and
`default_sidebar_tags` site settings. SidebarSectionLink records are
only created for categories and tags which the user has visibility on at
the point of user creation.
With this change, we're also adding the ability for admins to apply
changes to the `default_sidebar_categories` and `default_sidebar_tags`
site settings historically when changing their site setting. When a new
category/tag has been added to the default, the new category/tag will be
added to the sidebar for all users if the admin elects to apply the changes historically.
Like wise when a tag/category is removed, the tag/category will be
removed from the sidebar for all users if the admin elects to apply the
changes historically.
Internal Ref: /t/73500
Previously, when categories were not muted by default, we were sending message about unmuted topics (topics which user explicitly set notification level to watching)
The same mechanism can be used to fix a bug. When the user was explicitly watching topic, but category was muted, then the user was not informed about new reply.
Skipped invites were not counted at all and some invites could generate
more than one error and resulted in a grand total that was not equal to
the count of bulk invites.
This commit renames all secure_media related settings to secure_uploads_* along with the associated functionality.
This is being done because "media" does not really cover it, we aren't just doing this for images and videos etc. but for all uploads in the site.
Additionally, in future we want to secure more types of uploads, and enable a kind of "mixed mode" where some uploads are secure and some are not, so keeping media in the name is just confusing.
This also keeps compatibility with the `secure-media-uploads` path, and changes new
secure URLs to be `secure-uploads`.
Deprecated settings:
* secure_media -> secure_uploads
* secure_media_allow_embed_images_in_emails -> secure_uploads_allow_embed_images_in_emails
* secure_media_max_email_embed_image_size_kb -> secure_uploads_max_email_embed_image_size_kb
We previously had a system which would generate a 10x10px preview of images and add their URLs in a data-small-upload attribute. The client would then use that as the background-image of the `<img>` element. This works reasonably well on fast connections, but on slower connections it can take a few seconds for the placeholders to appear. The act of loading the placeholders can also break or delay the loading of the 'real' images.
This commit replaces the placeholder logic with a new approach. Instead of a 10x10px preview, we use imagemagick to calculate the average color of an image and store it in the database. The hex color value then added as a `data-dominant-color` attribute on the `<img>` element, and the client can use this as a `background-color` on the element while the real image is loading. That means no extra HTTP request is required, and so the placeholder color can appear instantly.
Dominant color will be calculated:
1. When a new upload is created
2. During a post rebake, if the dominant color is missing from an upload, it will be calculated and stored
3. Every 15 minutes, 25 old upload records are fetched and their dominant color calculated and stored. (part of the existing PeriodicalUpdates job)
Existing posts will continue to use the old 10x10px placeholder system until they are next rebaked
We observed that some sites seemingly put us in a tarpit when we attempt to pull hotlinked images. Increasing the timeout will help in these situations.
