The strict-dynamic CSP directive is supported in all our target browsers, and makes for a much simpler configuration. Instead of allowlisting paths, we use a per-request nonce to authorize `<script>` tags, and then those scripts are allowed to load additional scripts (or add additional inline scripts) without restriction.
This becomes especially useful when admins want to add external scripts like Google Tag Manager, or advertising scripts, which then go on to load a ton of other scripts.
All script tags introduced via themes will automatically have the nonce attribute applied, so it should be zero-effort for theme developers. Plugins *may* need some changes if they are inserting their own script tags.
This commit introduces a strict-dynamic-based CSP behind an experimental `content_security_policy_strict_dynamic` site setting.

It's complicated...we have multiple "anonymous" user concepts
in core, and even two classes called the exact same thing --
AnonymousUser.
The first case is Guardian::AnonymousUser, which is used for
people who are browsing the forum without being authenticated.
The second case is the model AnonymousUser, which is used when
a user is liking or posting anonymously via allow_anonymous_likes
or allow_anonymous_posting site settings.
We will untangle this naming nightmare later on...but for the
time being, only authenticated users who are pretending to be
anonymous should be able to like posts if allow_anonymous_likes
is on.
Why this change?
This is a first pass at adding an objects validator which main's job is
to validate an object against a defined schema which we will support. In
this pass, we are simply validating that properties that has been marked
as required are present in the object.
The `-ping` option significantly speeds up the ImageMagick `identify` command per our testing and the [documentation](https://imagemagick.org/script/command-line-options.php#ping):
> -ping
Efficiently determine these image characteristics: image number, the file name, the width and height of the image, whether the image is colormapped or not, the number of colors in the image, the number of bytes in the image, the format of the image (JPEG, PNM, etc.). Use +ping to ensure accurate image properties.
We already pass the `-ping` option in other places where the `identify` command is used, so it makes sense to use the option everywhere.

Why this change?
On CI, we have been seeing flaky system tests because ActiveRecord is
unable to checkout a connection. This patch is meant to help us debug
which thread is not returning the connection to the queue.
Fixes an issue where private topics that are quoted have an incorrectly formatted url when using a subfolder install.
This update returns a relative url that includes the base_path rather than a combination of base_url + base_path.
This commit changes `max_image_megapixels` to be used
as is without multiplying by 2 to give extra leway.
We found in reality this was just causing confusion
for admins, especially with the already permissive
40MP default.
This reverts commit 767b49232e.
If anything else (e.g. GTM integration) introduces a nonce/hash, then this change stops the splash screen JS to fail and makes sites unusable.
Removes duplication from LimitedEdit to see who can edit
posts, and also removes the old trust level setting check
since it's no longer necessary.
Also make it so staff can always edit since can_edit_post?
already has a staff escape hatch.
Why this change?
This commit introduces an experimental `type: objects` theme setting
which will allow theme developers to store a collection of objects as
JSON in the database. Currently, the feature is still in development and
this commit is simply setting up the ground work for us to introduce the
feature in smaller pieces.
What does this change do?
1. Adds a `json_value` column as `jsonb` data type to the `theme_settings` table.
2. Adds a `experimental_objects_type_for_theme_settings` site setting to
determine whether `ThemeSetting` records of with the `objects` data
type can be created.
3. Updates `ThemeSettingsManager` to support read/write access from the
`ThemeSettings#json_value` column.

post_links_allowed_groups is an odd check tied to
unrestricted_link_posting? in PostGuardian, in that
it doesn't have an escape hatch for staff like most
of the rest of these group based settings.
It doesn't make sense to exclude admins or mods from
posting links, so just always allow them to avoid confusion.
Browsers will ignore unsafe-inline if nonces or hashes are included in the CSP. When unsafe-inline is enabled, nonces and hashes are not required, so we can skip them.
Our strong recommendation remains that unsafe-inline should not be used in production.
We've changed access settings to be group membership based rather than based on the TL value directly. We kept both conditions here while we updated any plugins and themes. It should now be safe to remove.
JS assets added by plugins via `register_asset` will be outside the `assets/javascripts` directory, and are therefore exempt from being transpiled. That means that there isn't really any need to run them through DiscourseJsProcessor. Instead, we can just concatenate them together, and avoid the need for all the sprockets-wrangling.
This commit also takes the opportunity to clean up a number of plugin-asset-related codepaths which are no longer required (e.g. globs, handlebars)
Why this change?
Since 1dba1aca27, we have been remapping
the `<->` proximity operator in a tsquery to `&`. However, there is
another variant of it which follows the `<N>` pattern. For example, the
following text "end-to-end" will eventually result in the following
tsquery `end-to-end:* <-> end:* <2> end:*` being generated by Postgres.
Before this fix, the tsquery is remapped to `end-to-end:* & end:* <2>
end:*` by us. This is requires the search data which we store to contain
`end` at exactly 2 position apart. Due to the way we limit the
number of duplicates in our search data, the search term may end up not
matching anything. In bd32912c5e, we made
it such that we do not allow any duplicates when indexing a topic's
title. Therefore, search for `end-to-end` against a topic title with
`end-to-end` will never match because our index will only contain one
`end` term.
What does this change do?
We will remap the `<N>` variant of the proximity operator.
We were having a minor issue with emails with embedded images
that had newlines in the alt string; for example:
```
<p class="MsoNormal"><span style="font-size:11.0pt"><img width="898"
height="498" style="width:9.3541in;height:5.1875in" id="Picture_x0020_5"
src="cid:image003.png@01DA4EBA.0400B610" alt="A screenshot of a computer
program
Description automatically generated"></span><span
style="font-size:11.0pt"><o:p></o:p></span></p>
```
Once this was parsed and converted to markdown (or directly to HTML
in some cases), this caused an issue in the composer and the post
UI, where the markdown parser didn't know how to deal with this,
making the HTML show directly instead of showing an image.
The easiest way to deal with this is to just strip \n from image
alt and title attrs in the HTMLToMarkdown class.
These routes were previously rendered using Rails, and had a fairly fragile 2fa implementation in vanilla-js. This commit refactors the routes to be handled in the Ember app, removes the custom vanilla-js bundles, and leans on our centralized 2fa implementation. It also introduces a set of system specs for the behavior.
Safari has a bug which means that scripts with the `defer` attribute are executed before stylesheets have finished loading. This is being tracked at https://bugs.webkit.org/show_bug.cgi?id=209261.
This commit works around the problem by introducing a no-op inline `<script>` to the end of our HTML document. This works because defer scripts are guaranteed to run after inline scripts, and inline scripts are guaranteed to run after any preceding stylesheets.
Technically we only need this for Safari. But given that the cost is so low, it makes sense to include it everywhere rather than incurring the complexity of gating it by user-agent.
In a handful of situations, we need to verify a user's 2fa credentials before `current_user` is assigned. For example: login, email_login and change-email confirmation. This commit adds an explicit `target_user:` parameter to the centralized 2fa system so that it can be used for those situations.
For safety and clarity, this new parameter only works for anon. If some user is logged in, and target_user is set to a different user, an exception will be raised.
We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_level_to_tag_topics site setting to tag_topic_allowed_groups.
Previously, it was not possible to modify the sorting order of the `TopicQuery` result from a plugin. This feature adds support to specify custom sorting functionality in a plugin. We're using the `apply_modifier` method in the `DiscoursePluginRegistry` module to achieve it.

We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_level_for_user_api_key site setting to user_api_key_allowed_groups.
This isn't used by any of our plugins or themes, so very little fallout.
If configuring only moderators in a group based access setting, the mapping to the old setting wouldn't work correctly, because the case was unaccounted for.
This PR accounts for moderators group when doing the mapping.

- Decrease gravity, we come in too hot prioritizing too many new topics
- Remove all muted topics / categories and tags from the hot list
- Punish topics with zero likes in algorithm
This introduces a new experimental hot sort ordering.
It attempts to float top conversations by first prioritizing a topics with lots of recent activity (likes and users responding)
The schedule that updates hot topics is disabled unless the hidden site setting: `experimental_hot_topics` is enabled.
You can control "decay" with `hot_topic_gravity` and `recency` with `hot_topics_recent_days`
Data is stored in the new `topic_hot_scores` table and you can check it out on the `/hot` route once
enabled.

Previously only Sidekiq was allowed to generate more than one optimized image at the same time per machine. This adds an easy mechanism to allow the same in rake tasks and other tools.
Why this change?
While the constant does not change very often, we should still avoid
duplicating the value of a constant used on the server side in the
client side to avoid the values going out of sync.
Why this change?
Currently, is it hard to iteratively write a theme settings migrations
because our theme migrations system does not rollback. Therefore, we
want to allow theme developers to be able to write QUnit tests for their
theme migrations files enabling them to iteratively write their theme
migrations.
What does this change do?
1. Update `Theme#baked_js_tests_with_digest` to include all `ThemeField`
records of `ThemeField#target` equal to `migrations`. Note that we do
not include the `settings` and `themePrefix` variables for migration files.
2. Don't minify JavaScript test files becasue it makes debugging in
development hard.
This will make it easier to analyze rate limiting in reverse-proxy logs. To make this possible without a database lookup, we add the username to the encrypted `_t` cookie data.
We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_level_to_tag_topics site setting to tag_topic_allowed_groups.
When navigating straight to a topic the category was not displayed at
all because the categories were not loaded. Similarly, the categories
for suggested topics were not loaded either.
This commit adds a list of categories to topic view model class and
serializer.
We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_to_send_email_messages site setting to send_email_messages_allowed_groups.
Some plugins have names (e.g. discourse-x-yz) that
are totally different from what they are actually called,
and that causes issues when showing them in a sorted way
in the admin plugin list.
Now, we should use the setting category name from client.en.yml
if it exists, otherwise fall back to the name, for sorting.
This is what we do on the client to determine what text to
show for the plugin name as well.
We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_level_to_create_tag site setting to create_tag_allowed_groups.
This PR maintains backwards compatibility until we can update plugins and themes using this.
This was used by chat's HTML documentation experiment. That documentation experiment isn't being actively used/updated, but may be revisited in future. Therefore, this commit updates the jsdoc config to remove the custom theme, but keeps it functional (with the default jsdoc theme).
This fixes an issue where any string for an enum site setting
(such as TrustLevelSetting) would be converted to an integer
if the default value for the enum was an integer. This is an
issue because things like "admin" and "staff" would get silently
converted to 0 which is "valid" because it's TrustLevel[0],
but it's unexpected behaviour. It's best to just let the site
setting validator catch this broken value.
Why this change?
The `can survive cache miss` test in `spec/requests/stylesheets_controller_spec.rb`
was failing because the file was not found on disk for the cache to be
regenerated. This is because a test in
`spec/lib/stylesheet/manager_spec.rb` was removing the entire
`tmp/stylesheet-cache` directory which is incorrect because the folder
in the test environment further segretates the stylesheet caches based
on the process of the test.
What does this change do?
1. Introduce `Stylesheet::Manager.rm_cache_folder` method for the test
environment to properly clean up the cache folder.
2. Make `Stylesheet::Manager::CACHE_PATH` a private constant since the
cache path should be obtained from the `Stylesheet::Manager.cache_fullpath` method.
Why this change?
We have been running into flaky tests which seems to be related to
AR transaction problems. However, we are not able to reproduce this
locally and do not have sufficient information on our builds now to
debug the problem.
What does this change do?
Noe the following changes only applies when `ENV["GITHUB_ACTIONS"]` is
present.
This change introduces an RSpec around hook when `capture_log: true` has
been set for a test. The responsibility of the hook is to capture the
ActiveRecord debug logs and print them out.
We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_to_allow_self_wiki site setting to self_wiki_allowed_groups.
Nothing of note here. This is used in exactly one place, and there's no fallout.
When setting an old TL based site setting in the console e.g.:
SiteSetting.min_trust_level_to_allow_ignore = TrustLevel[3]
We will silently convert this to the corresponding Group::AUTO_GROUP. And vice-versa, when we read the value on the old setting, we will automatically get the lowest trust level corresponding to the lowest auto group for the new setting in the database.
Why this change?
Currently we only rerun failing tests to check if they are flaky tests
when there are 10 or less failing tests. When there are more than 10
failing tests in the first run, we assume that the odds of those tests
being flaky are low and do not rerun the tests. However, there was a bug
where we do not clean up the potential flaky tests being logged when
there are too many test failures. This resulted in those test failures
being treated as flaky tests.
What does this change do?
Clean up the flaky tests report when we do not rerun the tests.
A bug that allowed TL1 to convert other's posts to wiki.
The issue was introduced in this PR: https://github.com/discourse/discourse/pull/24999/files
The wiki can be created if a user is TL3 and it is their own post - default 3 for setting `SiteSetting.min_trust_to_allow_self_wiki`
In addition, a wiki can be created by staff and TL4 users for any post.
This changes the Plugins link in the admin sidebar to
be a section instead, which then shows all enabled plugin
admin routes (which are custom routes some plugins e.g.
chat define).
This is done via adding some special preloaded data for
all controllers based on AdminController, and also specifically
on Admin::PluginsController, to have the routes loaded without
additional requests on page load.
We just use a cog for all the route icons for now...we don't
have anything better.
Ability to automatically generate migration when site setting is changed from trust level to groups.
Example usage:

We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_level_to_allow_ignore site setting to ignore_allowed_groups.

We're changing the implementation of trust levels to use groups. Part of this is to have site settings that reference trust levels use groups instead. It converts the min_trust_level_to_allow_invite site setting to invite_allowed_groups.
Nothing much of note. This is used in one place and there's no fallout.
Using min_trust_to_create_topic and create_topic_allowed_groups together was part of #24740
Now, when plugins specs are fixed, we can safely remove that part of logic.
This is v0 of admin sidebar navigation, which moves
all of the top-level admin nav from the top of the page
into a sidebar. This is hidden behind a enable_admin_sidebar_navigation
site setting, and is opt-in for now.
This sidebar is dynamically shown whenever the user enters an
admin route in the UI, and is hidden and replaced with either
the:
* Main forum sidebar
* Chat sidebar
Depending on where they navigate to. For now, custom sections
are not supported in the admin sidebar.
This commit removes the experimental admin sidebar generation rake
task but keeps the experimental sidebar UI for now for further
testing; it just uses the real nav as the default now.
Before, when needed to get stats in a plugin, we called Core classes directly.
Introducing plugin API will decouple plugins from Core and give as more freedom
in refactoring stats in Core. Without this API, I wasn't able to do all refactorings
I wanted when working on d91456f.
