### What is this change?
The lounge category was replaced with the general category in https://github.com/discourse/discourse/pull/18097.
However, there are still a few references to the lounge category in code. In particular, `Category#seeded?` is erroring out in production looking for `SiteSetting.lounge_category_id`.
### Background
Several call sites use `FileStore#download` (through `Discourse.store.download`). In some cases the author seems aware that the method can raise an error if the download fails, and in some cases not. Because of this we're seeing some of these exceptions bubble all the way up and getting logged in production. Although they are not really actionable at that point. Rather each call site needs to be considered to figure out how to handle them.
### What is this change?
This change accomplishes primarily two things.
Firstly it separates the method into a safe version which will handle errors by returning `nil`, and an unsafe version which will re-package upstream errors in a new `FileStore::DownloadError` class.
Secondly it updates the call sites which have been doing error handling downstream to use the new safe version.
For backwards compatibility, there's an interim situation and a desired end state.
**Interim:**
```
FileStore#download → Old unsafe version. Will raise any error and show a deprecation warning.
FileStore#download! → New unsafe version. Will raise FileStore::DownloadError.
FileStore#download_safe → New safe version. Will return nil.
```
**Desired end-state:**
```
FileStore#download → New safe version. Will return nil.
FileStore#download! → New unsafe version. Will raise FileStore::DownloadError.
```
### What's next?
We need to do a quick audit of the call sites that are using the old unsafe version without any error handling, as well as check for call sites in plugins other repos. Follow-up PRs incoming.
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.
Currently `Topic#pm_topic_count` is a count of all personal messages tagged for a given tag. As a result, any user with access to PM tags can poll a sensitive tag to determine if a new personal message has been created using that tag even if the user does not have access to the personal message. We classify this as a minor leak in sensitive information.
With this commit, `Topic#pm_topic_count` is hidden from users by default unless the `display_personal_messages_tag_counts` site setting is enabled.
The presence service would retry `/presence/update` requests every second (or immediately in tests) in case where server returns 429 (rate limit) errors. That could lead to infinite spamming (until user refreshed tab/tabs)

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 a user checks "Open all external links in a new tab" preference
he expects not to be overruled by unrelated text selections.
Yet if text is selected during a link click the link is followed on
the same tab. This change corrects that.
There was an issue where if hashtag-cooked HTML was sent
to the ExcerptParser without the keep_svg option, we would
end up with empty </use> and </svg> tags on the parts of the
excerpt where the hashtag was, in this case when a post
push notification was sent.
Fixed this, and also added a way to only display a plaintext
version of the hashtag for cases like this via PrettyText#excerpt.
Meta topic: https://meta.discourse.org/t/android-keyboard-overlaps-text-when-flagging-with-something-else/249687?u=osama
On Android, it's currently not possible to scroll modals that take input from the user (such as the flagging modal) when the keyboard is open which means that the keyboard can cover up part of the modal with no way for the user to see the covered part without closing the keyboard. This commit adds some CSS to make these modals scrollable when the keyboard is open.
In the group member bulk edit menu we are displaying staff-only options
to non-staff. The requests are blocked by the back-end, so there is no
harm other than to the user experience.
Notably the individual user edit menu is correctly filtering out
unavailable options. This change brings the bulk edit menu in line with
that.
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.
This is a very subtle one. Setting the redirect URL is done by passing
a hash through a Discourse event. This is broken on Ruby 2 since the
support for keyword arguments in events was added.
In Ruby 2 the last argument is cast to keyword arguments if it is a
hash. The key point here is that creates a new copy of the hash, so
what the plugin is modifying is not the hash that was passed.
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.
```
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.
These accidental inclusions are mostly no-ops (because the method name is also included as an explicit symbol). The mistakes were made more obvious because syntax_tree adjusted the indentation of these methods
There are various performance issues with the Canvas in iOS Safari
that are causing crashes when processing images with spikes of over 100%
CPU usage. The cause of this is unknown, but profiling points to
CanvasRenderingContext2D.getImageData() and
CanvasRenderingContext2D.drawImage().
Until Safari makes some progress with OffscreenCanvas or other
alternatives we cannot support this workflow. We will revisit in 6
months.
This is gated behind the hidden `composer_ios_media_optimisation_image_enabled`
site setting for people who really still want to try using this.
