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
A while ago we increased group SMTP read and open timeouts
to address issues we were seeing with Gmail sometimes giving
really long timeouts for these values. The commit was:
3e639e4aa7
Now, we want to increase all SMTP read timeouts to 30s,
since the 5s is too low sometimes, and the ruby Net::SMTP
stdlib also defaults to 30s.
Also, we want to slightly tweak the group smtp email job
not to fail if the IncomingEmail log fails to create, or if
a ReadTimeout is encountered, to avoid retrying the job in sidekiq
again and sending the same email out.
* Remove unnecessary properties
* Use rem unit
* Add a drop shadow
* Make the "box shadow" slightly more subtle
* Use --d-border-radius
* Don't scale the "box shadow" on hover
* Scale down the on-hover size
* Make the button slightly larger
* Respect prefers-reduced-motion
* Use white rather than --secondary-or-primary
* Don't animate on-hover on mobile
During extensibility when we add post menu buttons we very much want access
to the topic.
The transformer does not include a `topic` attribute due to historical reasons.
Given we are going to move away from transforming long term and need to give
plugins access to topic when they are adding buttons, just add the extra
property
This commit moves some code out of UploadController#show_secure
so it can be reused in other controllers if a secure upload
needs to have permission checks run.
This commit adds another plugin modifier related to post
actions, similar to ae24e04a5e.
This will be used to exclude users who liked _and_ reacted to
the post, since now in discourse-reactions we make a Like when
a user reacts too. This will affect the display of the post footer.
Recently we changed the code to check permission in the backend. Example PR https://github.com/discourse/discourse/pull/25735
After those changes, `isInAnyGroups` and `userInAnyGroups` functions are not used anymore.
If you upload a portrait video or just a video that doesn't fit in the
normal video dimensions we want it to have a black background instead of
trying to render parts of the placeholder image as the video background.
This change removes the placeholder image for the video background when
the play button is clicked and replaces it with an all black background.
Affects the following settings:
delete_all_posts_and_topics_allowed_groups
experimental_new_new_view_groups
enable_experimental_admin_ui_groups
custom_summarization_allowed_groups
pm_tags_allowed_for_groups
chat_allowed_groups
direct_message_enabled_groups
chat_message_flag_allowed_groups
This turns off client: true for these group-based settings,
because there is no guarantee that the current user gets all
their group memberships serialized to the client. Better to check
server-side first.
Full post jump "SHIFT+K/J" not working if related topics are displayed
Amended logic so we unconditionally use full post jump on topic pages by
checking for .post-stream
The video placeholder play button is white, so on a video placeholder
that is also white it is very hard to see where the play button is, so
this change adds a dark grey transparent background to the play button
so that it stands out. This is similar to how we have done the
play/pause button on animated gifs.
When "lazy load categories" is enabled, only the categories present in
the sidebar are preloaded. This is insufficient because the parent
categories are necessary too for the sidebar to be rendered properly.
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.
This commit is the first of a series of commits that will allow themes to define complex settings types by declaring a schema of the setting structure that Discourse core will use to build a UI for the setting automatically. We implement the navigation logic and support for multiple levels of nesting in this commit and we'll continue building this new system gradually in future commits.

Reactions needs this to be able to filter out likes received
actions, where there is also an associated reaction, since
now most reactions also count as a like.
* FEATURE: shift+j and shift+k will scroll entire posts
When scrolling through topics with very long posts we would like to use
`shift+j` and `shift+k` to quickly move between posts.
This allows users to bypass the scroll within post behavior when zooming
through topics with keyboard shortcuts
This overloads the behavior of shift+k and j which can be used to scroll
through sections (new/latest/etc...)
* remove useless tests
These tests are testing nothing, no point carrying them around
When making sensitive changes to an account (adding 2FA or passkeys), we
require users to confirm their password. This is to prevent an attacker
from adding 2FA to an account they have access to.
However, on newly created accounts, we should not require this, it's an
extra step and it doesn't provide extra security (since the account was
just created). This commit makes it so that we don't require session
confirmation for accounts created less than 5 minutes ago.
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.
Internal topic: t/121431.
This would allow a theme component (or an API call) to reset the bump
date of a topic to a given post's created_at date.
I picked `post_id` as the parameter here because it provides a bit of
extra protection against accidentally resetting the bump date to a date
that doesn't make sense.
I attempted to add a test for related topics, as they are untested. This was a massive challenge as related topics are only rendered after
- a user has stopped typing
- there is a timeout after typing
Between system tests, acceptance tests, and stubbing requests, this was difficult. So here is the pr san test.
Why this change?
Backfilling can take a long time on a site with many users. As a
result, the `DistriburedMutex` will warn in the logs when the block takes
more than 60 seconds to complete. We can increase the lock validity but
the method is currently only called from a job which has a
`cluster_concurrency` set to `1`. Therefore, it is actually not
necessary for us to hold a `DistributedMutex` here.
What does this change do?
1. Removes the distributed mutex and adds a comment about the risk of
calling the `SidebarSiteSettingsBackfiller#backfill!` method.a
2. Delete old sidebar category section links in batches for all users
to avoid a single long running query.
