We've had the UploadReference table for some time now in core,
but it was added after ChatUpload was and chat was just never
moved over to this new system.
This commit changes all chat code dealing with uploads to create/
update/delete/query UploadReference records instead of ChatUpload
records for consistency. At a later date we will drop the ChatUpload
table, but for now keeping it for data backup.
The migration + post migration are the same, we need both in case
any chat uploads are added/removed during deploy.
When checking whether an existing upload should be secure
based on upload references, do not count deleted posts, since
there is still a reference attached to them. This can lead to
issues where e.g. an upload is used for a post then later on
a custom emoji.

This change has two goals:
- Fixes an issue when the user had zoomed the viewport and the popper would position on the opposite side
- Makes msg actions arguably more pleasant to the eye by preventing it to be right aligned with the message container
Prior to this fix trashed channels would still prevent a channel with the same slug to be created. This commit generates a new slug on trash and frees the slug for future usage.
The format used for the slug is: `YYYYMMDD-HHMM-OLD_SLUG-deleted` truncated to the max length of a channel name.
This commit allows us to set the channel slug when creating new chat
channels. As well as this, it introduces a new `SlugsController` which can
generate a slug using `Slug.for` and a name string for input. We call this
after the user finishes typing the channel name (debounced) and fill in
the autogenerated slug in the background, and update the slug input
placeholder.
This autogenerated slug is used by default, but if the user writes anything
else in the input it will be used instead.
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.
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.
This fixes a longstanding issue for sites with the
secure_uploads setting enabled. What would happen is a scenario
like this, since we did not check all places an upload could be
linked to whenever we used UploadSecurity to check whether an
upload should be secure:
* Upload is created and used for site setting, set to secure: false
since site setting uploads should not be secure. Let's say favicon
* Favicon for the site is used inside a post in a private category,
e.g. via a Onebox
* We changed the secure status for the upload to true, since it's been
used in a private category and we don't check if it's originator
was a public place
* The site favicon breaks :'(
This was a source of constant consternation. Now, when an upload is _not_
being created, and we are checking if an existing upload should be
secure, we now check to see what the first record in the UploadReference
table is for that upload. If it's something public like a site setting,
then we will never change the upload to `secure`.
We'd like to lean on the DNS caching service for more than the standard
DB and Redis hosts, but without having to add additional code each time.
Define a new environment variable
DISCOURSE_DNS_CACHE_ADDITIONAL_SERVICE_NAMES (admittedly a mouthful)
which is a list of service names to be added to the static list at
process execution time.
For example, plugin foo may reference two services that you want to
cache the address of. By specifying the following two variables in the
process environment, cache_critical_dns will perform the lookup
alongside the DB and Redis host variables.
```
DISCOURSE_DNS_CACHE_ADDITIONAL_SERVICE_NAMES='FOO_SERVICE1,FOO_SERVICE2'
FOO_SERVICE1='foo.service1.example.com'
FOO_SERVICE1_SRV='foo._tcp.example.com'
FOO_SERVICE2='foo.service2.example.com'
```
The behaviour when it comes to SRV record lookup is the same as
previously implemented for the `DISCOURSE_DB_..` and
`DISCOURSE_REDIS_..` variables.
For the purposes of the health checks, services defined in the list _are
always considered healthy_. This is a compromise for conveniences sake.
Defining a dynamic method for health checks at runtime is not practical.

Prior to this change, we were parsing `Post#cooked` every time we
serialize a post to extract the usernames of mentioned users in the
post. However, the only reason we have to do this is to support
displaying a user's status beside each mention in a post on the client side when
the `enable_user_status` site setting is enabled. When
`enable_user_status` is disabled, we should avoid having to parse
`Post#cooked` since there is no point in doing so.
