This is a backport of 84e13e9.
We caught it in logs, race condition led to this error:
ActiveRecord::RecordNotUnique
(PG::UniqueViolation: ERROR: duplicate key value violates unique constraint "user_statuses_pkey"
DETAIL: Key (user_id)=(15) already exists.)
The reason the problem happened was that we were checking if a user has status and if not inserting status:
if user_status
...
else
self.user_status = UserStatus.create!(status)
end
The problem is that it's possible that another request will insert status just after we check if status exists and just before our request call `UserStatus.create!(status)`. Using `upsert` fixes the problem because under the hood `upsert` generates the only SQL request that uses "INSERT ... ON CONFLICT DO UPDATE". So we do everything in one SQL query, and that query takes care of resolving possible conflicts.
The check used to be necessary because we validated the referrer too and
this bypass was a workaround a bug that is present in some browsers that
do not send the correct referrer.
When creating a group membership request, there is no character
limit on the 'reason' field. This can be potentially be used by
an attacker to create enormous amount of data in the database.
When EmbeddableHost is configured for a specific category and that category is deleted, then EmbeddableHost should be deleted as well.
In addition, migration was added to fix existing data.
Currently, `Tag#topic_count` is a count of all regular topics regardless of whether the topic is in a read restricted category or not. As a result, any users can technically poll a sensitive tag to determine if a new topic is created in a category which the user has not excess to. We classify this as a minor leak in sensitive information.
The following changes are introduced in this commit:
1. Introduce `Tag#public_topic_count` which only count topics which have been tagged with a given tag in public categories.
2. Rename `Tag#topic_count` to `Tag#staff_topic_count` which counts the same way as `Tag#topic_count`. In other words, it counts all topics tagged with a given tag regardless of the category the topic is in. The rename is also done so that we indicate that this column contains sensitive information.
3. Change all previous spots which relied on `Topic#topic_count` to rely on `Tag.topic_column_count(guardian)` which will return the right "topic count" column to use based on the current scope.
4. Introduce `SiteSetting.include_secure_categories_in_tag_counts` site setting to allow site administrators to always display the tag topics count using `Tag#staff_topic_count` instead.
0403cda1d1 introduced a regression where
topics in non read-restricted categories have its TopicTrackingState
MessageBus messages published with the `group_ids: [nil]` option. This
essentially means that no one would be able to view the message.
When a topic belongs to category that is read restricted but permission
has not been granted to any groups, publishing ceratin topic tracking state
updates for the topic will result in the `MessageBus::InvalidMessageTarget` error being raised
because we're passing `nil` to `group_ids` which is not support by
MessageBus.
This commit ensures that for said category above, we will publish the
updates to the admin groups.
This change adds `target` to the set of attributes allowed by the
HTML sanitizer which is applied to the description of a user_field.
The rationale for this change:
* If one puts a link (<a>...</a>) in the description of a user_field
that is present and/or required at sign-up, the expectation is that
a prospective new user will click on that link during sign-up.
* Without an appropriate `target` attribute on the link, the new page
will be loaded in the same window/tab as the sign-up form, but this
will obliterate any fields that the user had already filled-out on
the form. (E.g., hitting the back-button will return to an
empty form.)
* Such UX behavior is incredibly aggravating to new users.
This change allows an admin to add a `target` attribute to links, to
instruct the browser to open them in a different window/tab, leaving
a sign-up form intact.
We previously used post creator's guardian permissions which will raise an error if the reviewer added a staff-only (restricted) tag.

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.

Using a shared channel means that every user receives an update to the 'last_id' when *any* other user is logged out. If many users are being programmatically logged out at the same time, this can cause a very large number of message-bus polls.
This commit switches to use a user-specific channel, which means that each user has its own 'last id' which will only increment when they are logged out
When loading posts in a topic, the topic level guardian
checks are run multiple times even though all the posts belong to the
same topic. Profiling in production revealed that this accounted for a
significant amount of request time for a user that is not staff or anon.
Therefore, we're optimizing this by adding memoizing the topic level
calls in `PostGuardian`. Speficifally, the result of
`TopicGuardian#can_see_topic?` and `PostGuardian#can_create_post?`
method calls are memoized per topic.
Locally profiling shows a significant improvement for normal users
loading a topic with 100 posts.
Benchmark script command: `ruby script/bench.rb --unicorn --skip-bundle-assets --iterations 100`
Before:
```
topic user:
50: 114
75: 117
90: 122
99: 209
topic.json user:
50: 67
75: 69
90: 72
99: 162
```
After:
```
topic user:
50: 101
75: 104
90: 107
99: 184
topic.json user:
50: 53
75: 53
90: 56
99: 138
```
Instead of relying on the `ILIKE` operator to filter out image links, we
can instead rely on the `TopicLink#extension` column which allows us to
more efficiently filter out image links.
This optimization mainly affects topics that are link heavy which is
common in topics with alot of replies. When profiling a production
instance for a topic with 10K replies and 2.5K `topic_links`, this
optimization reduces the query time from ~18ms to around ~4ms.
Featured topics are eventually serialized by `ListableTopicSerializer`
which calls `Topic#image_url` which requires us to preload
`Topic#topic_thumbnails`.
* DEV: Remove enable_whispers site setting
Whispers are enabled as long as there is at least one group allowed to
whisper, see whispers_allowed_groups site setting.
* DEV: Always enable whispers for admins if at least one group is allowed.
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.
When user is watching category or tag (watching or watching first post) notifications are moved to other tab.
To achieve that and distinguish between post create to directly watched topics and indirectly watched topics, new notification type called `watching_category_or_tag` was introduced.
The guardian is useful for plugins to determine if the callback should
do anything. A common use case is to not do anything in the callback if
the user is anonymous.
* FIX: Use Category.secured(guardian) for hashtag datasource
Follow up to comments in #19219, changing the category
hashtag datasource to use Category.secured(guardian) instead
of Site.new(guardian).categories here since the latter does
more work for not much benefit, and the query time is the
same. Also eliminates some Hash -> Model back and forth
busywork. Add some more specs too.
* FIX: Server-side hashtag lookup cooking user loading
When we were using the PrettyText.options.currentUser
and parsing back and forth with JSON for the hashtag
lookups server-side, we had a bug where the user's
secure categories were not loaded since we never actually
loaded a User model from the database, only parsed it
from JSON.
This commit fixes the issue by instead using the
PretyText.options.userId and looking up the user directly
from the database when calling hashtag_lookup via the
PrettyText::Helpers code when cooking server-side. Added
the missing spec to check for this as well.
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.

In this PR, we introduced an option, that when all authenticators are disabled, but backup codes still exists, user can authenticate with those backup codes. This was reverted as this is not expected behavior.
https://github.com/discourse/discourse/pull/18982
Instead, when the last authenticator is deleted, backup codes should be deleted as well. Because this disables 2fa, user is asked to confirm that action by typing text.
In addition, UI for 2fa preferences was refreshed.
When finding the candidates for `Topic.similar_to`, we will now ignore
topics in categories where `Category#search_priority` has been set to
ignore and also topics in categories which the user has specifically
muted.

Note that we don't have a database table and a model for post mentions yet, and I decided to implement it without adding one to avoid heavy data migrations. Still, we may want to add such a model later, that would be convenient, we have such a model for mentions in chat.
Note that status appears on all mentions on all posts in a topic except of the case when you just posted a new post, and it appeared on the bottom of the topic. On such posts, status won't be shown immediately for now (you'll need to reload the page to see the status). I'll take care of it in one of the following PRs.
When a screened IP address is matched because it is either blocked or
allowed it should update match_count. This did not work because it
tried to validate the IP address and it failed as it matched with
itself.
Follow-up to 6357a3ce33
where we allowed a general API key scope for user status
GET/PUT/DELETE, this commit allows the same for the
UserApiKey system.
Previously we would trigger the event before the `Topic#deleted_at`
column has been updated making it hard for plugins to correctly work
with the model when its new state has not been persisted in the
database.
* FIX: Only modify secured sidebar links on user promotion/demotion
If a user is created populate their sidebar with the default
categories/tags that they have access to.
If a user is promoted to admin populate any new categories/tags that
they now have access to.
If an admin is demoted remove any categories/tags that they no longer
have access to.
This will only apply for "secured" categories. For example if these are
the default sitebar categories:
- general
- site feedback
- staff
and a user only has these sidebar categories:
- general
when they are promoted to admin they will only receive the "staff"
category. As this is a default category they didn't previously have
access to.
* Add spec, remove tag logic on update
Change it so that if a user becomes unstaged it used the "add" method
instead of the "update" method because it is essentially following the
on_create path.
On admin promotion/demotion remove the logic for updating sidebar tags because
we don't currently have the tag equivalent like we do for User.secure_categories.
Added the test case for when a user is promoted to admin it should
receive *only* the new sidebar categories they didn't previously have
access to. Same for admin demotion.
* Add spec for suppress_secured_categories_from_admin site setting
* Update tags as well on admin promotion/demotion
* only update tags when they are enabled
* Use new SidebarSectionLinkUpdater
We now have a SidebarSectionLinkUpdater
that was introduced in: fb2507c6ce
* remove empty line
The centralization helps in reducing code duplication in our code base
and more importantly, centralizing logic for guardian checks into a
single spot.
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.
This PR adds separate notification indicators for PMs and reviewables that have arrived since the last time the user opened the notifications menu.
The PM indicator is the strongest one of all three indicators followed by the reviewable indicator and then finally the blue indicator. This means that if there's a new PM and a new reviewable, then the PM indicator will be shown.

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.

Adds stats for API and user API requests similar to regular page views.
This comes with a new report to visualize API requests per day like the
consolidated page views one.
This commit introduce a new API for registering callbacks, which we'll execute when a user gets destroyed, and the `delete_posts` opt is true. The chat plugin registers one callback and queues a job to destroy every message from that user in batches.

In this previous commit I introduced a bug that prevented
a legitimate case for an existing user to redeem an invite,
where the email/domain were both blank and the invite was
still redeemable by the user. Fixes the issue and adds more
specs for that case.
This adds API scope for the user status. This also adds a get method to the user status controller. We didn't need a dedicated method that returns status before because the server returns status with user objects, but I think we need to provide this method for API clients.
