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.
If unaccent is called with quote-like Unicode characters then it can
generate invalid queries because some of the transformed quotes by
unaccent are not escaped and to_tsquery fails because of bad input.
This commits replaces more quote-like Unicode characters before
unaccent is called.
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.

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
* 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.
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.

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.

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.
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
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 commit fleshes out and adds functionality for the new `#hashtag` search and
lookup system, still hidden behind the `enable_experimental_hashtag_autocomplete`
feature flag.
**Serverside**
We have two plugin API registration methods that are used to define data sources
(`register_hashtag_data_source`) and hashtag result type priorities depending on
the context (`register_hashtag_type_in_context`). Reading the comments in plugin.rb
should make it clear what these are doing. Reading the `HashtagAutocompleteService`
in full will likely help a lot as well.
Each data source is responsible for providing its own **lookup** and **search**
method that returns hashtag results based on the arguments provided. For example,
the category hashtag data source has to take into account parent categories and
how they relate, and each data source has to define their own icon to use for the
hashtag, and so on.
The `Site` serializer has two new attributes that source data from `HashtagAutocompleteService`.
There is `hashtag_icons` that is just a simple array of all the different icons that
can be used for allowlisting in our markdown pipeline, and there is `hashtag_context_configurations`
that is used to store the type priority orders for each registered context.
When sending emails, we cannot render the SVG icons for hashtags, so
we need to change the HTML hashtags to the normal `#hashtag` text.
**Markdown**
The `hashtag-autocomplete.js` file is where I have added the new `hashtag-autocomplete`
markdown rule, and like all of our rules this is used to cook the raw text on both the clientside
and on the serverside using MiniRacer. Only on the server side do we actually reach out to
the database with the `hashtagLookup` function, on the clientside we just render a plainer
version of the hashtag HTML. Only in the composer preview do we do further lookups based
on this.
This rule is the first one (that I can find) that uses the `currentUser` based on a passed
in `user_id` for guardian checks in markdown rendering code. This is the `last_editor_id`
for both the post and chat message. In some cases we need to cook without a user present,
so the `Discourse.system_user` is used in this case.
**Chat Channels**
This also contains the changes required for chat so that chat channels can be used
as a data source for hashtag searches and lookups. This data source will only be
used when `enable_experimental_hashtag_autocomplete` is `true`, so we don't have
to worry about channel results suddenly turning up.
------
**Known Rough Edges**
- Onebox excerpts will not render the icon svg/use tags, I plan to address that in a follow up PR
- Selecting a hashtag + pressing the Quote button will result in weird behaviour, I plan to address that in a follow up PR
- Mixed hashtag contexts for hashtags without a type suffix will not work correctly, e.g. #ux which is both a category and a channel slug will resolve to a category when used inside a post or within a [chat] transcript in that post. Users can get around this manually by adding the correct suffix, for example ::channel. We may get to this at some point in future
- Icons will not show for the hashtags in emails since SVG support is so terrible in email (this is not likely to be resolved, but still noting for posterity)
- Additional refinements and review fixes wil
The hidden site setting `suppress_secured_categories_from_admin` will
suppress visibility of categories without explicit access from admins
in a few key areas (category drop downs and topic lists)
It is not intended to be a security wall since admins can amend any site
setting. Instead it is feature that allows hiding the categories from the
UI.
Admins will still be able to see topics in categories without explicit
access using direct URLs or flags.

This commit adds some protections in InviteRedeemer to ensure that email
can never be nil, which could cause issues with inviting the invited
person to private topics since there was an incorrect inner join.
If the email is nil and the invite is scoped to an email, we just use
that invite.email unconditionally. If a redeeming_user (an existing
user) is passed in when redeeming an email, we use their email to
override the passed in email. Otherwise we just use the passed in
email. We now raise an error after all this if the email is still nil.
This commit also adds some tests to catch the private topic fix, and
some general improvements and comments around the invite code.
This commit also includes a migration to delete TopicAllowedUser records
for users who were mistakenly added to topics as part of the invite
redemption process.
It is likely that a new admin user was created as just a regular user
before being promoted to admin so this change will update the sidebar
link records for any users that are promoted to admin. This way if any
of the default side bar categories or tags are restricted to admins
these new admins will have those added to their sidebar as well.
You can easily replicate this issue locally (prior to this fix) by using
`rails admin:create` where it creates a user first, then it is promoted
to admin. This means it would receive the default categories of regular
user, but never receive the ones they should have access to as an admin.
As part of this change I did drop the `!` from
`SidebarSectionLink.insert_all` so that it would add any new records
that were missing, but not throw a unique constraint error trying to add
any existing records.

Previously, we didn't have a site-wide setting to set the default behavior for user profile visibility and user presence features. But we already have a user preference for that.
This commit fixes a regression introduced in 8979adc where under certain conditions the groups syncing logic in Discourse Connect would try to add users to groups they're already members of and cause errors when users try to sign in using Discourse Connect.
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.

Discourse Connect can be used to manage group memberships of users by including a `add_groups`, `remove_groups` or `groups` attribute in the Discourse Connect payload. However, additions/deletions of users from groups aren't logged to the groups logs (available at `/g/<group>/manage/logs`) which can cause confusions to admins they try to figure out when/how users were added or removed from a group. This commit makes Discourse Connect add entries to the groups logs when it makes changes to users' group memberships.
Theme javascript is now minified using Terser, just like our core/plugin JS bundles. This reduces the amount of data sent over the network.
This commit also introduces sourcemaps for theme JS. Browser developer tools will now be able show each source file separately when browsing, and also in backtraces.
For theme test JS, the sourcemap is inlined for simplicity. Network load is not a concern for tests.
Previously, compiling theme 'extra_js' was done with a number of steps. Each theme_field would be compiled into its own value_baked column, and then the JavascriptCache content would be built by concatenating all of those compiled values.
This commit streamlines things by removing the value_baked step. The raw value of all extra_js theme_fields are passed directly to the ThemeJavascriptCompiler, and then the result is stored in the JavascriptCache.
In itself, this commit should not cause any behavior change. It is designed to open the door to more advanced compilation features which have interdependencies between different source files (e.g. template colocation, sourcemaps).
