This commit operates at three levels of abstraction:
1. We want to prevent user history rows from being unbounded in size.
This commit adds rails validations to limit the sizes of columns on
user_histories,
2. However, we don't want to prevent certain actions from being
completed if these columns are too long. In those cases, we truncate
the values that are given and store the truncated versions,
3. For endpoints that perform staff actions, we can further control
what is permitted by explicitly validating the params that are given
before attempting the action,
In AdminDashboardData we have a bunch of problem checks implemented as methods on that class. This PR absolves it of the responsibility by promoting each of those checks to a first class ProblemCheck. This way each of them can have their own priority and arbitrary functionality can be isolated in its own class.
Think "extract class" refactoring over and over. Since they were all moved we can also get rid of the @@problem_syms class variable which was basically the old version of the registry now replaced by ProblemCheck.realtime.
In addition AdminDashboardData::Problem value object has been entirely replaced with the new ProblemCheck::Problem (with compatible API).
Lastly, I added some RSpec matchers to simplify testing of problem checks and provide helpful error messages when assertions fail.
Previously, if the sso= payload was invalid Base64, but signed correctly, there would be no useful log or error. This commit improves things by:
- moving the base64 check before the signature checking so that it's properly surfaced
- split the ParseError exception into PayloadParseError and SignatureError
- add user-facing errors for both of those
- add/improve spec for both
Adds a site setting to include a post's content in penalty message.
When silencing/suspending a user from a post, or a reviewable with
a post, adds an option to include a post's content in the email
message by default.
This commit changes the wording of the 50 site settings that
previously had the shortest descriptions (e.g. City for Disputes
was described as City for Disputes...) using AI-generated and then
human curated descriptions based on the Forum Helper persona
on Discourse Meta.
In future we may want to do more of these, this is only a first pass.

When a post is created by an incoming email, we show
an envelope icon on it which then opens a modal with the
raw email contents. Previously this was staff (admin+mod)
only, but now this commit adds the `view_raw_email_allowed_groups`
site setting, so any group can be added to give users permission
to see this.
Why this change?
Previously in cac60a2c6b, I added support
for `type: "category"` for a property in the theme objects schema. This
commit extend the work previously to add support for types `topic`,
`post`, `group`, `upload` and `tag`.
Why this change?
This change adds validation for the default value for `type: objects` theme
settings when a setting theme field is uploaded. This helps the theme
author to ensure that the objects which they specifc in the default
value adhere to the schema which they have declared.
When an error is encountered in one of the objects, the error
message will look something like:
`"The property at JSON Pointer '/0/title' must be at least 5 characters
long."`
We use a JSON Pointer to reference the property in the object which is
something most json-schema validator uses as well.
What does this change do?
1. This commit once again changes the shape of hash returned by
`ThemeSettingsObjectValidator.validate`. Instead of using the
property name as the key previously, we have decided to avoid
multiple levels of nesting and instead use a JSON Pointer as the key
which helps to simplify the implementation.
2 Introduces `ThemeSettingsObjectValidator.validate_objects` which
returns an array of validation error messages for all the objects
passed to the method.
This PR adds a new scheduled problem check that simply tries to connect to Twitter OAuth endpoint to check that it's working. It is using the default retry strategy of 2 retries 30 seconds apart.
Why this change?
This change supports a property of `type: category` in the schema that
is declared for a theme setting object. Example:
```
sections:
type: objects
schema:
name: section
properties:
category_property:
type: category
```
The value of a property declared as `type: category` will have to be a
valid id of a row in the `categories` table.
What does this change do?
Adds a property value validation step for `type: category`. Care has
been taken to ensure that we do not spam the database with a ton of
requests if there are alot of category typed properties. This is done by
walking through the entire object and collecting all the values for
properties typed category. After which, a single database query is
executed to validate which values are valid.
Why this change?
Firstly, note that this is not a security commit because this feature is
still in development and should not be used anywhere.
The reason we want to set a limit here is to greatly reduce the
possibility of a DoS attack in the future via `ThemeSetting` where
someone would set an arbituary large json string in
`ThemeSetting#json_value` and causing the server to run out of resources
trying to serialize/deserialize the value.
What does this change do?
Adds an ActiveRecord validation to ensure that the bytesize of the json
string being stored is smaller than or equal to 0.5mb. We believe 0.5mb
is a decent limit for now but we can review the limit in the future if
we believe it is too small.
Why this change?
The logic for validating a theme setting's value and default value was
not consistent as each part of the code would implement its own logic.
This is not ideal as the default value may be validated differently than
when we are setting a new value. Therefore, this commit seeks to
refactor all the validation logic for a theme setting's value into a
single service class.
What does this change do?
Introduce the `ThemeSettingsValidator` service class which holds all the
necessary helper methods required to validate a theme setting's value
Why this change?
This commit updates `ThemeSettingsObjectValidator` to validate a
property's value against the validations listed in the schema.
For string types, `min_length`, `max_length` and `url` are supported.
For integer and float types, `min` and `max` are supported.
Why this change?
This change adds property value validation to `ThemeSettingsObjectValidator`
for the following types: "string", "integer", "float", "boolean", "enum". Note
that this class is not being used anywhere yet and is still in
development.
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.
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.
When we launched the new illegal flag type, there were a few problems with the translations:
The translation for the message in the e-mail was missing and in the review queue, the message read: "Is this it's illegal?"
In this PR the missing translation key has been added. For the review queue there was a coupling of the name rendering to whether the flag is of "custom" type, but this is also used for deciding whether we render the textbox for additional details. I think these two things should not be coupled together. For now I have instead hard-coded the existing "custom" types when formatting the name. We can potentially improve this later.
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.
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.
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.
Running Discourse 3.2 stable under Ember 3 will technically be possible, but is only intended as a short-term migration point. This commit adds an admin warning for sites which are using this configuration, to make it clear that themes and plugins are unlikely to support the configuration.

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.
