When Discourse first introduced brotli support, reverse-proxy/CDN support for passing through the accept-encoding header to our NGINX server was very poor. Therefore, a separate `/brotli_assets/...` path was introduced to serve the brotli assets. This worked well, but introduces additional complexity and inconsistencies.
Nowadays, Brotli encoding is well supported, so we don't need the separate paths any more. Requests can be routed to the asset `.js` URLs, and NGINX will serve the brotli/gzip version of the asset automatically.
This commit introduces a new feature that allows theme developers to manage the transformation of theme settings over time. Similar to Rails migrations, the theme settings migration system enables developers to write and execute migrations for theme settings, ensuring a smooth transition when changes are required in the format or structure of setting values.
Example use cases for the theme settings migration system:
1. Renaming a theme setting.
2. Changing the data type of a theme setting (e.g., transforming a string setting containing comma-separated values into a proper list setting).
3. Altering the format of data stored in a theme setting.
All of these use cases and more are now possible while preserving theme setting values for sites that have already modified their theme settings.
Usage:
1. Create a top-level directory called `migrations` in your theme/component, and then within the `migrations` directory create another directory called `settings`.
2. Inside the `migrations/settings` directory, create a JavaScript file using the format `XXXX-some-name.js`, where `XXXX` is a unique 4-digit number, and `some-name` is a descriptor of your choice that describes the migration.
3. Within the JavaScript file, define and export (as the default) a function called `migrate`. This function will receive a `Map` object and must also return a `Map` object (it's acceptable to return the same `Map` object that the function received).
4. The `Map` object received by the `migrate` function will include settings that have been overridden or changed by site administrators. Settings that have never been changed from the default will not be included.
5. The keys and values contained in the `Map` object that the `migrate` function returns will replace all the currently changed settings of the theme.
6. Migrations are executed in numerical order based on the XXXX segment in the migration filenames. For instance, `0001-some-migration.js` will be executed before `0002-another-migration.js`.
Here's a complete example migration script that renames a setting from `setting_with_old_name` to `setting_with_new_name`:
```js
// File name: 0001-rename-setting.js
export default function migrate(settings) {
if (settings.has("setting_with_old_name")) {
settings.set("setting_with_new_name", settings.get("setting_with_old_name"));
}
return settings;
}
```
Internal topic: t/109980
Two changes were introduced:
1. Reorder links on sidebar section is removed. Clicking and holding the mouse for 250ms was unintuitive;
2. Fixed bugs when reorder is done in edit modal.
As part of #23816, which sought to strip out thousand separators, we also accidentally strip out signs. This is making it impossible to disable some settings which require a -1 to disable. Instead of stripping non-digits, strip anything that isn't a sign or a digit.
Why this change?
When the URL `/t/1234?preview_theme_id=21` is loaded, we redirect to
`/t/<topic slug>/1234` stripping the `preview_theme_id` query params.
What does this change do?
This change builds on 61248652cd and
simply adds the `preview_theme_id` query param when redirecting.
* FIX: Secure upload post processing race condition
This commit fixes a couple of issues.
A little background -- when uploads are created in the composer
for posts, regardless of whether the upload will eventually be
marked secure or not, if secure_uploads is enabled we always mark
the upload secure at first. This is so the upload is by default
protected, regardless of post type (regular or PM) or category.
This was causing issues in some rare occasions though because
of the order of operations of our post creation and processing
pipeline. When creating a post, we enqueue a sidekiq job to
post-process the post which does various things including
converting images to lightboxes. We were also enqueuing a job
to update the secure status for all uploads in that post.
Sometimes the secure status job would run before the post process
job, marking uploads as _not secure_ in the background and changing
their ACL before the post processor ran, which meant the users
would see a broken image in their posts. This commit fixes that issue
by always running the upload security changes inline _within_ the
cooked_post_processor job.
The other issue was that the lightbox wrapper link for images in
the post would end up with a URL like this:
```
href="/secure-uploads/original/2X/4/4e1f00a40b6c952198bbdacae383ba77932fc542.jpeg"
```
Since we weren't actually using the `upload.url` to pass to
`UrlHelper.cook_url` here, we weren't converting this href to the CDN
URL if the post was not in a secure context (the UrlHelper does not
know how to convert a secure-uploads URL to a CDN one). Now we
always end up with the correct lightbox href. This was less of an issue
than the other one, since the secure-uploads URL works even when the
upload has become non-secure, but it was a good inconsistency to fix
anyway.
This commit introduces a new endpoint to search categories and uses it
instead of the categories map that is preloaded using SiteSerializer.
This feature is enabled only when the hidden site setting
lazy_load_categories is enabled and should be used only on sites with
many categories.
Why this change?
The `PostsController#create` action allows arbitrary topic custom fields
to be set by any user that can create a topic. Without any restrictions,
this opens us up to potential security issues where plugins may be using
topic custom fields in security sensitive areas.
What does this change do?
1. This change introduces the `register_editable_topic_custom_field` plugin
API which allows plugins to register topic custom fields that are
editable either by staff users only or all users. The registered
editable topic custom fields are stored in `DiscoursePluginRegistry` and
is called by a new method `Topic#editable_custom_fields` which is then
used in the `PostsController#create` controller action. When an unpermitted custom fields is present in the `meta_data` params,
a 400 response code is returned.
2. Removes all reference to `meta_data` on a topic as it is confusing
since we actually mean topic custom fields instead.
This commit adds a new Revise... action that can be taken
for queued post reviewables. This will open a modal where
the user can select a Reason from a preconfigured list
(or by choosing Other..., a custom reason) and provide feedback
to the user about their post.
The post will be rejected still, but a PM will also be sent to
the user so they have an opportunity to improve their post when
they resubmit it.
This is part 2 (of 3) for passkeys support.
This adds a hidden site setting plus routes and controller actions.
1. registering passkeys
Passkeys are registered in a two-step process. First, `create_passkey`
returns details for the browser to create a passkey. This includes
- a challenge
- the relying party ID and Origin
- the user's secure identifier
- the supported algorithms
- the user's existing passkeys (if any)
Then the browser creates a key with this information, and submits it to
the server via `register_passkey`.
2. authenticating passkeys
A similar process happens here as well. First, a challenge is created
and sent to the browser. Then the browser makes a public key credential
and submits it to the server via `passkey_auth_perform`.
3. renaming/deleting passkeys
These routes allow changing the name of a key and deleting it.
4. checking if session is trusted for sensitive actions
Since a passkey is a password replacement, we want to make sure to confirm the user's identity before allowing adding/deleting passkeys. The u/trusted-session GET route returns success if user has confirmed their session (and failed if user hasn't). In the frontend (in the next PR), we're using these routes to show the password confirmation screen.
The `/u/confirm-session` route allows the user to confirm their session with a password. The latter route's functionality already existed in core, under the 2FA flow, but it has been abstracted into its own here so it can be used independently.

When a user creates or edits a post, we already were updating
the security of uploads in the post based on site settings and
their access control post, which is important since these uploads
may be switched from secure/not secure based on configuration.
The `with_secure_uploads?` method on a post is used to determine
whether to use the secure-uploads URL for all uploads in the post,
regardless of their individual security, so if this is false and
some of the posts are still secure when rebaking, we end up with
broken URLs.
This commit just makes it so rebaking via the UI also re-evaluates
upload security so that when the post is loaded again after processing,
all of the uploads have the correct security.
Why this change?
Back in May 17 2023 along with the release of Discourse 3.1, we announced
on meta that the legacy hamburger dropdown navigation menu is
deprecated and will be dropped in Discourse 3.2. This is the link to the announcement
on meta: https://meta.discourse.org/t/removing-the-legacy-hamburger-navigation-menu-option/265274
## What does this change do?
This change removes the `legacy` option from the `navigation_menu` site
setting and migrates existing sites on the `legacy` option to the
`header dropdown` option.
All references to the `legacy` option in code and tests have been
removed as well.
Currently, if you set an integer site setting in the admin interface and include thousands separators, you will silently configure the wrong value.
This PR replaces TextField inputs for integer site settings with NumberField. It also cleans the numeric input of any non-digits in the backend in case any separators make it through.
This is part 1 of 3, split up of PR #23529. This PR refactors the
webauthn code to support passkey authentication/registration.
Passkeys aren't used yet, that is coming in PRs 2 and 3.

This commit adds support for an optional `prompt` parameter in the
payload of the /session/sso_provider endpoint. If an SSO Consumer
adds a `prompt=none` parameter to the encoded/signed `sso` payload,
then Discourse will avoid trying to login a not-logged-in user:
* If the user is already logged in, Discourse will immediately
redirect back to the Consumer with the user's credentials in a
signed payload, as usual.
* If the user is not logged in, Discourse will immediately redirect
back to the Consumer with a signed payload bearing the parameter
`failed=true`.
This allows the SSO Consumer to simply test whether or not a user is
logged in, without forcing the user to try to log in. This is useful
when the SSO Consumer allows both anonymous and authenticated access.
(E.g., users that are already logged-in to Discourse can be seamlessly
logged-in to the Consumer site, and anonymous users can remain
anonymous until they explicitly ask to log in.)
This feature is similar to the `prompt=none` functionality in an
OpenID Connect Authentication Request; see
https://openid.net/specs/openid-connect-core-1_0.html#AuthRequest
Some sites have a large number of categories and fetching the category
IDs or category topic IDs just to build another query can take a long
time or resources (i.e. memory).
* FIX: Return 403 instead of redirect on username routes when hidding profiles
* Updated raised error to better reflect the problem to the user
* implemented suggested changes
Previously, a "`some_not_allowed`" warning message was appeared in composer even when all the users mentioned via group are already invited to the private message directly or via other groups.
The hidden site setting max_drafts_per_user defaults to 10_000 drafts per user.
The longest key should be "topic_<MAX_BIG_INT>" which is 25 characters.
In #20135 we prevented invalid inputs from being accepted in category setting form fields on the front-end. We didn't do anything on the back-end at that time, because we were still discussing which path we wanted to take. Eventually we decided we want to move this to a new CategorySetting model.
This PR moves the require_topic_approval and require_reply_approval from custom fields to the new CategorySetting model.
This PR is nearly identical to #20580, which migrated num_auto_bump_daily, but since these are slightly more sensitive, they are moved after the previous one is verified.
Previous to this change when both `normalize_emails` and `hide_email_address_taken`
is enabled the expected `account_exists` email was only sent on exact email
matches.
This expands it so it also sends an email to the canonical email owner.
Why this change?
Currently, we do not have an easy way to test themes and theme components
using Rails system tests. While we support QUnit acceptance tests for
themes and theme components, QUnit acceptance tests stubs out the server
and setting up the fixtures for server responses is difficult and can lead to a
frustrating experience. System tests on the other hand allow authors to
set up the test fixtures using our fabricator system which is much
easier to use.
What does this change do?
In order for us to allow authors to run system tests with their themes
installed, we are adding a `upload_theme` helper that is made available
when writing system tests. The `upload_theme` helper requires a single
`directory` parameter where `directory` is the directory of the theme
locally and returns a `Theme` record.
Until now, we have allowed testing themes in production environments via `/theme-qunit`. This was made possible by hacking the ember-cli build so that it would create the `tests.js` bundle in production. However, this is fundamentally problematic because a number of test-specific things are still optimized out of the Ember build in production mode. It also makes asset compilation significantly slower, and makes it more difficult for us to update our build pipeline (e.g. to introduce Embroider).
This commit removes the ability to run qunit tests in production builds of the JS app when the Embdroider flag is enabled. If a production instance of Discourse exists exclusively for the development of themes (e.g. discourse.theme-creator.io) then they can add `EMBER_ENV: development` to their `app.yml` file. This will build the entire app in development mode, and has a significant performance impact. This must not be used for real production sites.
This commit also refactors many of the request specs into system specs. This means that the tests are guaranteed to have Ember assets built, and is also a better end-to-end test than simply checking for the presence of certain `<script>` tags in the HTML.
We're seeing a large number of log noise from this endpoint due to malicious scanners that are trying to send clever params and seeing if they can break something.
This change simply rescues any NoMethodError during parameter parsing and re-raises a Discourse::InvalidParameters exception, which will be caught and render a 400.
They're both constant per-instance values, there is no need to store them
in the session. This also makes the code a bit more readable by moving
the `session_challenge_key` method up to the `DiscourseWebauthn` module.
Why this change?
As part of our ongoing efforts to security harden the Discourse
application, we are adding the `cross_origin_opener_policy_header` site setting
which allows the `Cross-Origin-Opener-Policy` response header to be set on requests
that preloads the Discourse application. In more technical terms, only
GET requests that are not json or xhr will have the response header set.
The `cross_origin_opener_policy_header` site setting is hidden for now
for testing purposes and will either be released as a public site
setting or be remove if we decide to be opinionated and ship a default
for the `Cross-Origin-Opener-Policy` response header.
Streaming doesn't work for anonymous users because we scope updates to the current user. Since they can only see cached summaries, we can skip the streaming parameter and update it directly with the ajax response.
`ReviewableQueuedPost` got refactored a while back to use the more
appropriate `target_created_by` for the user of the post being queued
instead of `created_by`. The change was not extended to the `DELETE
/review/:id` endpoint leading to error responses for a user attempting
to deleting their own queued post.
This fix extends the `Reviewable` lookup implementation in
`ReviewablesController#destroy` and Guardian implementation to account
for this change.
When we receive the stream parameter, we'll queue a job that periodically publishes partial updates, and after the summarization finishes, a final one with the completed version, plus metadata.
`summary-box` listens to these updates via MessageBus, and updates state accordingly.
This commit removes any logic in the app and in specs around
enable_experimental_hashtag_autocomplete and deletes some
old category hashtag code that is no longer necessary.
It also adds a `slug_ref` category instance method, which
will generate a reference like `parent:child` for a category,
with an optional depth, which hashtags use. Also refactors
PostRevisor which was using CategoryHashtagDataSource directly
which is a no-no.
Deletes the old hashtag markdown rule as well.
In #20135 we prevented invalid inputs from being accepted in category setting form fields on the front-end. We didn't do anything on the back-end at that time, because we were still discussing which path we wanted to take. Eventually we decided we want to move this to a new CategorySetting model.
This PR moves the num_auto_bump_daily from custom fields to the new CategorySetting model.
In addition it sets the default value to 0, which exhibits the same behaviour as when the value is NULL.
This is a similar fix to 32d4810e2b
Why this change?
Prior to this change, there is a bug in `TopicsController#bulk`
where it does not dismiss new unred posts in sub-subcategories when the
`category_id` and `include_subcategories=true` params are present. This
is because the controller did not account for sub-subcategories when
fetching the category ids of the new topics that should be dismissed.
This commit fixes the problem by relying on the `Category.subcategory_ids` class
method which accounts for sub-subcategories.
What is the problem here?
In multiple controllers, we are accepting a `limit` params but do not
impose any upper bound on the values being accepted. Without an upper
bound, we may be allowing arbituary users from generating DB queries
which may end up exhausing the resources on the server.
What is the fix here?
A new `fetch_limit_from_params` helper method is introduced in
`ApplicationController` that can be used by controller actions to safely
get the limit from the params as a default limit and maximum limit has
to be set. When an invalid limit params is encountered, the server will
respond with the 400 response code.
What is the context for this change?
Prior to this change, there is a bug in `TopicsController#reset_new`
where it does not dismiss new topics in sub-subcategories when the
`category_id` and `include_subcategories=true` params are present. This
is because the controller did not account for sub-subcategories when
fetching the category ids of the new topics that should be dismissed.
This commit fixes the problem by relying on the `Category.subcategory_ids` class
method which accounts for sub-subcategories.
Recently we started giving admins a notice in the advice panel when their translations have become outdated due to changes in core. However, we didn't include any additional information.
This PR adds more information about the outdated translation inside the site text edit page, together with an option to dismiss the warning.
We have a number of raw comments indicating that certain methods and classes are deprecated and marked for removal. This change turn those comments into deprecation warnings so that we can 1) see them in the logs of our own hosting and 2) give some warning to self hosters.
Why this change?
Prior to this change, we would only return tags that are used in at
least one public topic. However, this is confusing for users because the
tag could be used in a restricted category and that is not considered a
"public" topic. Instead, we will just display all the tags in the edit
tags navigation modal as long as it is visible to the user.
Why this change?
Prior to this change, dismissing unreads posts did not publish the
changes across clients for the same user. As a result, users can end up
seeing an unread count being present but saw no topics being loaded when
visiting the `/unread` route.
* FEATURE: Inline topic summary. Cached version accessible to everyone.
Anons and non-members of the `custom_summarization_allowed_groups_map` groups can see cached summaries for any accessible topic. After the first 12 hours and if the posts to summarize have changed, allowed users clicking on the button will automatically re-generate it.
* Ensure chat summaries work and prevent model hallucinations when there are no messages.
This PR adds a feature to help admins stay up-to-date with their translations. We already have protections preventing admins from problems when they update their overrides. This change adds some protection in the other direction (where translations change in core due to an upgrade) by creating a notice for admins when defaults have changed.
Terms:
- In the case where Discourse core changes the default translation, the translation override is considered "outdated".
- In the case above where interpolation keys were changed from the ones the override is using, it is considered "invalid".
- If none of the above applies, the override is considered "up to date".
How does it work?
There are a few pieces that makes this work:
- When an admin creates or updates a translation override, we store the original translation at the time of write. (This is used to detect changes later on.)
- There is a background job that runs once every day and checks for outdated and invalid overrides, and marks them as such.
- When there are any outdated or invalid overrides, a notice is shown in admin dashboard with a link to the text customization page.
Known limitations
The link from the dashboard links to the default locale text customization page. Given there might be invalid overrides in multiple languages, I'm not sure what we could do here. Consideration for future improvement.
Some plugins call require_plugin with a wrong argument instead of the
plugin name. In a production environment that used to be a warning, but
there is no reason to keep it like that in a testing environment
because the issue will continue to be ignored.
Follow-up to b27e12445d
This commit adds 2 new site settings `default_sidebar_link_to_filtered_list` and `default_sidebar_show_count_of_new_items` to control the default values for the navigation menu preferences that were added in the linked commit (`sidebar_link_to_filtered_list` and `sidebar_show_count_of_new_items` respectively).
What is the problem?
Before this change, we were relying on the `/tags` endpoint which
returned all the tags that are visible to a give user on the site leading to potential performance problems.
The attribute keys of the response also changes based on the `tags_listed_by_group` site setting.
What is the fix?
This commit fixes the problems listed above by creating a dedicate `#list` action in the
`TagsController` to handle the listing of the tags in the edit
navigation menu tags modal. This is because the `TagsController#index`
action was created specifically for the `/tags` route and the response
body does not really map well to what we need. The `TagsController#list`
action added here is also much safer since the response is paginated and
we avoid loading a whole bunch of tags upfront.
]When changing fonts in the `/wizard/steps/styling` step of
the wizard, users would not see the font loaded straight away,
having to switch to another one then back to the original to
see the result. This is because we are using canvas to render
the style preview and this fails with a Chrome-based intervention
when font loading is taking too long:
> [Intervention] Slow network is detected. See
https://www.chromestatus.com/feature/5636954674692096 for more details.
Fallback font will be used while loading:
https://sea2.discourse-cdn.com/business7/fonts/Roboto-Bold.ttf?v=0.0.9
We can get around this by manually loading the fonts selected using
the FontFace JS API when the user selects them and before rerendering
the canvas. This just requires preloading more information about the
fonts if the user is admin so the wizard can query this data.
This is the first of a number of PRs aimed at helping admins manage their translation overrides. It simply adds a list of available interpolation keys below the input field when editing an override.
It also includes custom interpolation key.
Updates the interface for implementing summarization strategies and adds a cache layer to summarize topics once.
The cache stores the final summary and each chunk used to build it, which will be useful when we have to extend or rebuild it.
Communities can use sidebar or header dropdown, therefore navigation menu is a better name settings in 2 places:
- Old user sidebar preferences;
- Site setting about default tags and categories.
* FEATURE: Content custom summarization strategies.
This PR establishes a pattern for plugins to register alternative ways of summarizing content by extending a class that defines an interface.
Core controls which strategy we'll use and who has access to it through the `summarization_strategy` and `custom_summarization_allowed_groups`. It also defines the UI for summarizing topics.
Other plugins can access this summarization mechanism and implement their features, removing cross-plugin customizations, as it currently happens between chat and the discourse-ai plugin.
* Group membership validation and rate limiting
* Work with objects instead of classes
* Port summarization feature from discourse-ai to chat
* Rename available summaries to 'Top Replies' and 'Summary'
1. ember proxy stuff still isn't in a great shape, live-reload doesn't work yet, uploads made w/o subfolder won't work, custom fonts don't work, service worker doesn't work. But otherwise it's fine :P
2. I don't know why `HTTP_IF_MODIFIED_SINCE` can be an empty string. Don't have time to investigate, and fast_blank makes this fix an easy solution ;)
* DEV: Implement staff logs for user columns edits
* deleted extra space in staff logger detail string, deleted string when no changes are made, added basic test coverage for EditDirectoryColumnsController
* fixed change made to #self.staff_actions un UserHistory
* implemented a method that builds the details, previous_values and new_values in a dynamic way
* removed details of changes
* refactored small merge
Calling pluck is instantly making a SELECT, while passing the relationship allows rails to build a correct query.

Post Count (2.7ms) SELECT COUNT(*) FROM "posts" WHERE "posts"."deleted_at" IS NULL AND "posts"."topic_id" IN (SELECT "topics"."id" FROM "topics" WHERE "topics"."deleted_at" IS NULL AND "topics"."id" IN (1, 3, 4))
```
Display modal for combined new and unread view with options:

What is the problem?
The user messages routes are currently routed by the server to
`UserActionsController#private_messages`. However, the method is
essentially a no-op and does not do any preloading. As a result, when we
load the user private messages routes, the client ends up having to
issue another request to the server to get more information about the
user profile currently being viewed. This extra request is triggered by
the `user` model's `findDetails` method that is called from the `user`
route in the `afterModel` hook.
What is the solution?
The `user` model's `findDetails` method actually checks the preload
store to see if the `user_${username}` key is present in the store and
if it is, it will use the preloaded data instead of triggering another
request. Since the user private messages routes are nested under the
user route on the client side, we have to rely on the
`UsersController#show` controller action on the server side for the user private
messages route as the `UsersController#show` controller action preloads
the required user information for the client side.
Prior to this commit, we didn't have RTL versions of our admin and plugins CSS bundles and we always served LTR versions of those bundles even when users used an RTL locale, causing admin and plugins UI elements to never look as good as when an LTR locale was used. Example of UI issues prior to this commit were: missing margins, borders on the wrong side and buttons too close to each other etc.
This commit creates an RTL version for the admin CSS bundle as well as RTL bundles for all the installed plugins and serves those RTL bundles to users/sites who use RTL locales.
This commit adds modifiers that allow plugins to change how categories and groups are prefetched into the application and listed in the respective controllers.
Possible use cases:
- prevent some categories/groups from being prefetched when the application loads for performance reasons.
- prevent some categories/groups from being listed in their respective index pages.
Allow admins to edit Community section. This includes drag and drop reorder, change names, delete and reset to default.
Visual improvements introduced in edit community section modal are available in edit custom section form as well. For example:
- drag and drop links to change their position;
- smaller icon picker.
This commit introduces a new `within_user_updater_transaction` event that's triggered inside the transaction that saves user updates in `UserUpdater`. Plugins can hook into the transaction using the event to include custom changes in the transaction. Callbacks for this event receive 2 arguments:
1. the user being saved
2. the changed attributes that are passed to `UserUpdater`.
There's also new modifier in this commit called `users_controller_update_user_params` to allow plugins to allowlist custom params in the `UsersController` which eventually end up getting passed as attributes to the `UserUpdater` and the new `within_user_updater_transaction` event where they can be used to perform additional updates using the custom params.
-----
New API is used in https://github.com/discourse/discourse-mailinglist-integration/pull/1.
When a user chooses to move a topic/message to an existing topic/message, they can now opt to merge the posts chronologically (using a checkbox in the UI).
The field more_topic_url is already included in the response preloaded in categories#index
However this field was missing if a request was subsequently made to update the page using
the end-points /categories_and_latest or /categories_and_top. This could lead the client
app to display incorrect information if it relied on this information to update the UI.
This commit deprecates the `modify_user_params` method in `UsersController` in favor of a new modifier that replaces that method whose entire purpose is to allow plugins to monkey-patch it to permit custom params in the controller. We now have the "modifier" system which can achieve the same results but in a safer and easier way. The modifier that replaces the deprecated method is included in PR https://github.com/discourse/discourse/pull/21737.
What is this change required?
I noticed that actions in `SidebarSectionsController` resulted in
lots of N+1 queries problem and I wanted a solution to
prevent such problems without having to write N+1 queries tests. I have
also used strict loading for `SidebarSection` queries in performance
sensitive spots.
Note that in this commit, I have also set `config.active_record.action_on_strict_loading_violation = :log`
for the production environment so that we have more visibility of
potential N+1 queries problem in the logs. In development and test
environment, we're sticking with the default of raising an error.
When uploading images via direct to S3 upload, we were
assuming that we could not pre-emptively check the file
size because the client may do preprocessing to reduce
the size, and UploadCreator could also further reduce the
size.
This, however, is not true of gifs, so we would have an
issue where you upload a gif > the max_image_size_kb
setting and had to wait until the upload completed for
this error to show.
Now, instead, when we direct upload gifs to S3, we check
the size straight away and present a file size error to
the user rather than making them wait. This will increase
meme efficiency by approximately 1000%.
What is the problem?
In `SvgSpriteController#search` and `SvgSpriteController#icon_picker_search`, the controller actions
was using the `RailsMultisite::ConnectionManagement.with_hostname` API
but `params[:hostname]` was always `nil` because the routes does not
have a `:hostname` param component and the client does not ever pass the
`:hostname` param when making the request. When `RailsMultisite::ConnectionManagement.with_hostname` is
used with a `nil` argument, it ends up connecting to the default
multisite database. Usually this would be bad because we're allowing a
site in a multisite setup to connect to another site but thankfully no
private data is being leaked here.
What is the fix?
Since `SvgSpriteController#search` and `SvgSpriteController#icon_picker_search` are login required route,
there is no need for us to switch database connections. The fix here is
to simply remove the use of `RailsMultisite::ConnectionManagement.with_hostname`.
