It used to embed the objects which could lead to duplicated objects
when the same user or category was used multiple times (user was admin,
moderator and category or category was parent for multiple categories).
The automation plugin has 4 custom field types that are array typed. However, array typed custom fields are deprecated and should be migrated to JSON type.
This commit does a couple of things:
1. Migrate all four custom fields to JSON
2. Fix a couple of small bugs that have been discovered while migrating the custom fields to JSON (see the comments on this commit's PR for details https://github.com/discourse/discourse/pull/26939)
This reverts commit 0f4520867b.
This has led to two problems:
1. An incompatibility with Cloudflare's "auto minify" feature. They've deprecated this feature because of incompatibility with modern JS syntax. But unfortunately it will remain enabled on existing properties until 2024-08-05.
2. Discourse fails to boot in Safari 15. This is strange, because Safari does support all the required features in our production JS bundles. Even more strangely, things start working as soon as you open the developer tools. That suggests the cause could be a Safari bug rather than a simple incompatibility.
Reverting while we work out a path forward on both those issues.
decorator-transforms (https://github.com/ef4/decorator-transforms) is a modern replacement for babel's plugin-proposal-decorators. It provides a decorator implementation using modern browser features, without needing to enable babel's full suite of class feature transformations. This improves the developer experience and performance.
In local testing with Google's 'tachometer' tool, this reduces Discourse's 'init-to-render' time by around 3-4% (230ms -> 222ms).
It reduces our initial gzip'd JS payloads by 3.2% (2.43MB -> 2.35MB), or 7.5% (14.5MB -> 13.4MB) uncompressed.
Ignored columns can only be dropped when its associated post-deploy
migration has been promoted to a regular migration. This is so because
Discourse doesn't rely on a schema file system to setup a brand new
database and thus the column information will be loaded by the
application first before the post-deploy migration runs.
If there's ever a circular reference in categories, don't go into an infinite loop when generating the category slug.
Instead, keep track of parent ids, and bail out as soon as we're encountering one more than once.
In #22851 we added a dependent strategy for deleting upload references when a draft is destroyed. This, however, didn't catch all cases, because we still have some code that issues DELETE drafts queries directly to the database. Specifically in the weekly cleanup job handled by Draft#cleanup!.
This PR fixes that by turning the raw query into an ActiveRecord #destroy_all, which will invoke the dependent strategy that ultimately deletes the upload references. It also includes a post migration to clear orphaned upload references that are already in the database.
This commit introduces the `run_theme_migration` spec helper to allow
theme developers to write RSpec tests for theme migrations. For example,
this allows the following RSpec test to be written in themes:
```
RSpec.describe "0003-migrate-small-links-setting migration" do
let!(:theme) { upload_theme_component }
it "should set target property to `_blank` if previous target component is not valid or empty" do
theme.theme_settings.create!(
name: "small_links",
theme: theme,
data_type: ThemeSetting.types[:string],
value: "some text, #|some text 2, #, invalid target",
)
run_theme_migration(theme, "0003-migrate-small-links-setting")
expect(theme.settings[:small_links].value).to eq(
[
{ "text" => "some text", "url" => "#", "target" => "_blank" },
{ "text" => "some text 2", "url" => "#", "target" => "_blank" },
],
)
end
end
```
This change is being introduced because we realised that writting just
javascript tests for the migrations is insufficient since javascript
tests do not ensure that the migrated theme settings can actually be
successfully saved into the database. Hence, we are introduce this
helper as a way for theme developers to write "end-to-end" migrations
tests.
... wasn't working because it wasn't storing the proper "action" value.
Issue was that we were using the "action" parameter which is being used by Rails to determine which controller action to call.
We need to use the "action_key" parameter instead.
At the moment, there is no way to create a group of related watched words together. If a user needed a set of words to be created together, they'll have to create them individually one at a time.
This change attempts to allow related watched words to be created as a group. The idea here is to have a list of words be tied together via a common `WatchedWordGroup` record. Given a list of words, a `WatchedWordGroup` record is created and assigned to each `WatchedWord` record. The existing WatchedWord creation behaviour remains largely unchanged.

In the "Consolidated Pageviews with Browser Detection (Experimental)"
report we used the same color for "Known Crawler" and "Other pageviews"
which makes the report confusing to look at, this commit makes them
different.
This commit introduces a few changes as a result of
customer issues with finding why a topic was relisted.
In one case, if a user edited the OP of a topic that was
unlisted and hidden because of too many flags, the topic
would get relisted by directly changing topic.visible,
instead of going via TopicStatusUpdater.
To improve tracking we:
* Introduce a visibility_reason_id to topic which functions
in a similar way to hidden_reason_id on post, this column is
set from the various places we change topic visibility
* Fix Post#unhide! which was directly modifying topic.visible,
instead we use TopicStatusUpdater which sets visibility_reason_id
and also makes a small action post
* Show the reason topic visibility changed when hovering the
unlisted icon in topic status on topic titles
Selecting the +subcategories option does not work sometimes when "lazy
load categories" is enabled because the subcategories may not be
fetched. This ensures that subcategories are loaded by requesting them
before being used.
In a large forum with millions of users and millions of user_fields
updating the list of dropdown user field options will result in a
502 now due to the large number of fields.
This commit moves the indexing into a job.
Our 'page_view_crawler' / 'page_view_anon' metrics are based purely on the User Agent sent by clients. This means that 'badly behaved' bots which are imitating real user agents are counted towards 'anon' page views.
This commit introduces a new method of tracking visitors. When an initial HTML request is made, we assume it is a 'non-browser' request (i.e. a bot). Then, once the JS application has booted, we notify the server to count it as a 'browser' request. This reliance on a JavaScript-capable browser matches up more closely to dedicated analytics systems like Google Analytics.
Existing data collection and graphs are unchanged. Data collected via the new technique is available in a new 'experimental' report.
This ensures we only ever store correct post and topic timing when the client
notifies.
Previous to this change we would blindly trust the client.
Additionally this has error correction code that will correct the last seen
post number when you visit a topic with incorrect timings.
This commit addresses an issue for sites where secure_uploads
is turned on after the site has been operating without it for
some time.
When uploads are linked when they are used inside a post,
we were setting the access_control_post_id unconditionally
if it was NULL to that post ID and secure_uploads was true.
However this causes issues if an upload has been used in a
few different places, especially if a post was previously
used in a PM and marked secure, so we end up with a case of
the upload using a public post for its access control, which
causes URLs to not use the /secure-uploads/ path in the post,
breaking things like image uploads.
We should only set the access_control_post_id if the post is the first time the
upload is referenced so it cannot hijack uploads from other places.
When lazy load categories is enabled, categories should be loaded with
user activity items and drafts because the categories may not be
preloaded on the client side.
This will automatically enable the glimmer header when all installed themes/plugins are ready. This replaces the old group-based site setting.
In 'auto' mode, we check for calls to deprecated APIs (e.g. decorateWidget) which affect the old header. If any are present, we stick to the old header implementation and print a message to the console alongside the normal deprecation messages.
To override this automatic behavior, a new `glimmer_header_mode` site setting can be set to 'disabled' or 'enabled'.
This change also means that our test suite is running with the glimmer header. This unveiled a couple of small issues (e.g. some incorrect `aria-*` and `alt` text) which are now fixed. A number of selectors had to be updated to ensure the tests were clicking the actual `<button>` elements rather than the surrounding `<li>` elements.
This modifier allows plugins to alter the outcome of
`should_secure_uploads?` on a Post record, for cases when
plugins need post-attached uploads to always be secure (or
not secure) in specific scenarios.
This method name is a bit confusing; with_secure_uploads implies
it may return a block or something with the uploads of the post,
and has_secure_uploads implies that it's checking whether the post
is linked to any secure uploads.
should_secure_uploads? communicates the true intent of this method --
which is to say whether uploads attached to this post should be
secure or not.
* DEV: Add `topic_embed_import_create_args` plugin modifier
This modifier allows a plugin to change the arguments used when creating
a new topic for an imported article.
For example: let's say you want to prepend "Imported: " to the title of
every imported topic. You could use this modifier like so:
```ruby
# In your plugin's code
plugin.register_modifier(:topic_embed_import_create_args) do |args|
args[:title] = "Imported: #{args[:title]}"
args
end
```
In this example, the modifier is prepending "Imported: " to the `title` in the `create_args` hash. This modified title would then be used when the new topic is created.
This PR improves the performance of the `most_replied_to_users` method on the `UserSummary` model.
### Old Query
```ruby
post_query
.joins(
"JOIN posts replies ON posts.topic_id = replies.topic_id AND posts.reply_to_post_number = replies.post_number",
)
# We are removing replies by @user, but we can simplify this by getting the using the user_id on the posts.
.where("replies.user_id <> ?", @user.id)
.group("replies.user_id")
.order("COUNT(*) DESC")
.limit(MAX_SUMMARY_RESULTS)
.pluck("replies.user_id, COUNT(*)")
.each { |r| replied_users[r[0]] = r[1] }
```
### Old Query with corrections
```ruby
post_query
.joins(
"JOIN posts replies ON posts.topic_id = replies.topic_id AND replies.reply_to_post_number = posts.post_number",
)
# Remove replies by @user but instead look on loaded posts (we do this so we don't count self replies)
.where("replies.user_id <> posts.user_id")
.group("replies.user_id")
.order("COUNT(*) DESC")
.limit(MAX_SUMMARY_RESULTS)
.pluck("replies.user_id, COUNT(*)")
.each { |r| replied_users[r[0]] = r[1] }
```
### New Query
```ruby
post_query
.joins(
"JOIN posts replies ON posts.topic_id = replies.topic_id AND posts.reply_to_post_number = replies.post_number",
)
# Only include regular posts in our joins, this makes sure we don't have the bloat of loading private messages
.joins(
"JOIN topics ON replies.topic_id = topics.id AND topics.archetype <> 'private_message'",
)
# Only include visible post types, so exclude posts like whispers, etc
.joins(
"AND replies.post_type IN (#{Topic.visible_post_types(@user, include_moderator_actions: false).join(",")})",
)
.where("replies.user_id <> posts.user_id")
.group("replies.user_id")
.order("COUNT(*) DESC")
.limit(MAX_SUMMARY_RESULTS)
.pluck("replies.user_id, COUNT(*)")
.each { |r| replied_users[r[0]] = r[1] }
```
# Conclusion
`most_replied_to_users` was untested, so I introduced a test for the logic, and have confirmed that it passes on both the new query **AND** the old query.
Thank you @danielwaterworth for the debugging assistance.
We will be collecting the logo URL and the site's default locale values along with existing basic details to display the site on the Discourse Discover listing page. It will be included only if the site is opted-in by enabling the "`include_in_discourse_discover`" site setting.
Also, we no longer going to use `about.json` and `site/statistics.json` endpoints retrieve these data. We will be using only the `site/basic-info.json` endpoint.
When a user is manually deactivated, they should not be deleted by our background job that purges inactive users.
In addition, site settings keywords should accept an array of keywords.
Previously the problem check registry simply looked at the subclasses of ProblemCheck. This was causing some confusion in environments where eager loading is not enabled, as the registry would appear empty as a result of the classes never being referenced (and thus never loaded.)
This PR changes the approach to a more explicit one. I followed other implementations (bookmarkable and hashtag autocomplete.) As a bonus, this now has a neat plugin entry point as well.
Why this change?
This is a follow up to 897be75941.
When updating `net-smtp` from `0.4.x` to `0.5.x`, our test suite passed
but the error `ArgumentError: SMTP-AUTH requested but missing user name`
was being thrown in production leading to emails being failed to send
out via SMTP.
This commit adds a test to ensure that our production SMTP settings will
at least attemp to connect to an SMTP server.
## Why this change?
The previous implementation of the method generated the query to find the relevant topics and iterated over the results, processing them.
This behavior made difficult reusing or changing the query logic in classes extending `CategoryList`.
This commit extracts the query logic into another method called `relevant_topics_query ` which can be reused or overwritten in descendant classes.
This was originally introduced in #26071, but that PR was closed, because the requirements changed. This PR lifts only the relevant parts, since they are a prerequisite for the new admin notice system.
This enables the following in Discourse AI
```
plugin.register_modifier(:chat_allowed_bot_user_ids) do |user_ids, guardian|
if guardian.user
mentionables = AiPersona.mentionables(user: guardian.user)
allowed_bot_ids = mentionables.map { |mentionable| mentionable[:user_id] }
user_ids.concat(allowed_bot_ids)
end
user_ids
end
```
some bots that are id < 0 need to be discoverable in search otherwise people can not talk to them.

When "lazy load categories" is enabled and parent_category_id was set,
the query fetching categories contained a contradiction filtering both
by parent_category_id and parent_category_id = NULL.
When categories are loaded by the frontend, the parent category is
looked up by ID and the `parentCategory` is set with the result. If the
categories returned are not in order, the parent category may miss.
We were using `OFFSET`/`LIMIT` to query topics without an 'ORDER'. Without an explicit order, postgres makes no guarantees about which rows will be returned for each query. This commit adds `ORDER BY id ASC` so that our sitemaps behave consistently.
All our link validation, and conversion from url -> route/model/query is expensive and prone to bugs. Instead, if people enter a link, we can just use it as-is.
Originally all this extra logic was added to handle unusual situations like `/safe-mode`, `/my/...`, etc. However, all of these are now handled correctly by our Ember router, so there is no need for it.
Now, we just pass the user-supplied `href` directly to the SectionLink component, and let Ember handle routing to it when clicked.
The only functional change here is that we no longer validate internal links by parsing them with the Ember router. But I'd argue this is fine, because the previous logic would cause both false positives (e.g. `/t/123` would be valid, even if topic 123 doesn't exist), and false negatives (for routes which are server-side only, like the new AI share pages).
We were incorrectly using `return` in a block which was causing exceptions at runtime. These exceptions were not causing much issues as they are in defer block.
While working on writing a test for this specific case, I noticed that our `upsert_custom_fields` function was using rails `update_all` which is not updating the `updated_at` timestamp. This commit also fixes it and adds a test for it.
In #26122 we promoted all problem checks defined as class methods on AdminDashboardData to their own first-class ProblemCheck instances.
This PR continues that by promoting problem checks that are implemented as blocks as well. This includes updating a couple plugins that have problem checks.
This is a follow up to e2da72b76c.
Why this change?
According to https://web.dev/articles/preload-critical-assets,
> By preloading a certain resource, you are telling the browser that you would like to fetch it sooner than the browser would otherwise discover it because you are certain that it is important for the current page.
The preload resource hint is meant to tell the browser to fetch
resources that it would not discover upfront or early. However, we are
not using it the right way because we are literally adding the resource
hint right before a `<script>` tag which means the browser would have
discovered the resource even without the resource hint.
What does this change do?
This commit removes the preload resource hint which are added right
before script tags since the optimization here is highly questionable at the expense of making
our initial DOM larger.
We never use that information and this also fixes an issue with the BCC plugin which ends up triggering a rate-limit because we were publishing a "NEW_PRIVATE_MESSAGE" to the user sending the BCC for every recipients 💥
Internal - t/118283
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.
There are a couple of reasons for this.
The first one is practical, and related to eager loading. Since /lib is not eager loaded, when the application boots, ProblemCheck["identifier"] will be nil because the child classes aren't loaded.
The second one is more conceptual. There turns out to be a lot of inter-dependencies between the part of the problem check system that live in /app and the parts that live in /lib, which probably suggests it should all go in /app.
This change creates a user setting that they can toggle if
they don't want to receive unread notifications when someone closes a
topic they have read and are watching/tracking it.
Why this change?
There are two problematic queries in question here when loading
notifications in various tabs in the user menu:
```
SELECT "notifications".*
FROM "notifications"
LEFT JOIN topics ON notifications.topic_id = topics.id
WHERE "notifications"."user_id" = 1338 AND (topics.id IS NULL OR topics.deleted_at IS NULL)
ORDER BY notifications.high_priority AND NOT notifications.read DESC,
NOT notifications.read AND notifications.notification_type NOT IN (5,19,25) DESC,
notifications.created_at DESC
LIMIT 30;
```
and
```
EXPLAIN ANALYZE SELECT "notifications".*
FROM "notifications"
LEFT JOIN topics ON notifications.topic_id = topics.id
WHERE "notifications"."user_id" = 1338
AND (topics.id IS NULL OR topics.deleted_at IS NULL)
AND "notifications"."notification_type" IN (5, 19, 25)
ORDER BY notifications.high_priority AND NOT notifications.read DESC, NOT notifications.read DESC, notifications.created_at DESC LIMIT 30;
```
For a particular user, the queries takes about 40ms and 26ms
respectively on one of our production instance where the user has 10K notifications while the site has 600K notifications in total.
What does this change do?
1. Adds the `index_notifications_user_menu_ordering` index to the `notifications` table which is
indexed on `(user_id, (high_priority AND NOT read) DESC, (NOT read)
DESC, created_at DESC)`.
1. Adds a second index `index_notifications_user_menu_ordering_deprioritized_likes` to the `notifications`
table which is indexed on `(user_id, (high_priority AND NOT read) DESC, (NOT read AND notification_type NOT IN (5,19,25)) DESC, created_at DESC)`. Note that we have to hardcode the like typed notifications type here as it is being used in an ordering clause.
With the two indexes above, both queries complete in roughly 0.2ms. While I acknowledge that there will be some overhead in insert,update or delete operations. I believe this trade-off is worth it since viewing notifications in the user menu is something that is at the core of using a Discourse forum so we should optimise this experience as much as possible.
Why this change?
Prior to this change, the `CategoryList#find_relevant_topics` method was
loading and allocating all `CategoryFeaturedTopic` records in the
database to eventually only just use its `category_id` and `topic_id`
column. On a site with many `CategoryFeaturedTopic` records, the loading
of the ActiveRecord objects is a source of bottleneck.
The other problem with the `CategoryList#find_relevant_topics` method is
that it is unconditionally loading all records from the database even if
the user does not have access to the category. This again is wasteful.
What does this change do?
This commit makes it such that `CategoryList#find_relevant_topics` is
called only after `CategoryList#find_categories` in the `CategoryList#initialize`
method so that we can filter featured topics against categories that the
user has access to.
The second change is that Instead of loading `CategoryFeaturedTopic` records, we make an
inner join agains the `topics` table instead and skip any allocation of
`CatgoryFeaturedTopic` ActiveRecord objects.
As part of problem checks refactoring, we're moving some data to be DB backed. In this PR it's the tracking of problem check execution. When was it last run, when was the last problem, when should it run next, how many consecutive checks had problems, etc.
This allows us to implement the perform_every feature in scheduled problem checks for checks that don't need to be run every 10 minutes.
Users can hide their public profile and presence information by checking
“Hide my public profile and presence features” on the
`u/{username}/preferences/interface` page. In that case, we also don't
want to return user status from the server.
This work has been started in https://github.com/discourse/discourse/pull/23946.
The current PR fixes all the remaining places in Core.
Note that the actual fix is quite simple – a5802f484d.
But we had a fair amount of duplication in the code responsible for
the user status serialization, so I had to dry that up first. The refactoring
as well as adding some additional tests is the main part of this PR.
Now forums can enroll their sites to be showcased in the Discourse [Discover](https://discourse.org/discover) directory. Once they enable the site setting `include_in_discourse_discover` to enroll their forum the `CallDiscourseHub` job will ping the `api.discourse.org/api/discover/enroll` endpoint. Then the Discourse Hub will fetch the basic details from the forum and add it to the review queue. If the site is approved then the forum details will be displayed in the `/discover` page.
Also, remove experimental setting and simply use top_menu for feature detection
This means that when people eventually enable the hot top menu, there will
be topics in it

Previously, problem checks were all added as either class methods or blocks in AdminDashboardData. Another set of class methods were used to add and run problem checks.
As of this PR, problem checks are promoted to first-class citizens. Each problem check receives their own class. This class of course contains the implementation for running the check, but also configuration items like retry strategies (for scheduled checks.)
In addition, the parent class ProblemCheck also serves as a registry for checks. For example we can get a list of all existing check classes through ProblemCheck.checks, or just the ones running on a schedule through ProblemCheck.scheduled.
After this refactor, the task of adding a new check is significantly simplified. You add a class that inherits ProblemCheck, you implement it, add a test, and you're good to go.
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
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.
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.
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.
When we insert into the hot set we add things with a score of 0
This means that if hot has more than batch size items in it with a score, then the 0s don't get an initial score
This corrects the situation by always ensuring we re-score:
1. batch size high scoring topics
2. (new) batch size recently bumped topics

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.
Affects the following settings:
* whispers_allowed_groups
* anonymous_posting_allowed_groups
* personal_message_enabled_groups
* shared_drafts_allowed_groups
* here_mention_allowed_groups
* uploaded_avatars_allowed_groups
* ignore_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.
Why this change?
This is caused by a regression in
59839e428f, where we stopped saving the
`Theme` object because it was unnecessary. However, it resulted in the
`after_save` callback not being called and hence
`Theme#update_javascript_cache!` not being called. As a result, some
sites were reporting that after runing a theme migration, the defaults
for the theme settings were used instead of the settings overrides
stored in the database.
What does this change do?
Add a call to `Theme#update_javascript_cache!` after running theme
migrations.
This fixes a bug where the sidebar categories would not be loaded when
the categories were lazy loaded because the sidebar uses the preloaded
category list, which was empty.
We just completed the 3.2 release, which marks a good time to drop some previously deprecated columns.
Since the column has been marked in ignored_columns, it has been inaccessible to application code since then. There's a tiny risk that this might break a Data Explorer query, but given the nature of the column, the years of disuse, and the fact that such a breakage wouldn't be critical, we accept it.
1. Don't show visited line for hot filter, it is in random order
2. Don't count likes on non regular posts (eg: whispers / small actions)
3. Don't count participants in non regular posts
1. Serial likers will just like a bunch of posts on the same topic, this will
heavily inflate hot score. To avoid artificial "heat" generated by one user only count
the first like on the topic within the recent_cutoff range per topic
2. When looking at recent topics prefer "unique likers", defer to total likes on
older topics cause we do not have an easy count for unique likers
3. Stop taking 1 off like_count, it is not needed - platforms like reddit
allow you to like own post so they need to remove it.
Why this change?
Returning an array makes it hard to immediately retrieve a setting by
name and makes the retrieval an O(N) operation. By returning an array,
we make it easier for us to lookup a setting by name and retrieval is
O(1) as well.
The `deprecate_column` helper would change its behavior based on the current `Discourse::VERSION`. This means that 'finalizing' a stable release introduces a previously untested behavior change.
Much better to keep it as a deprecation until manual action is taken to introduce the breaking change.
Internal links always notify and add internal connections in topics.
This adds a special feature that lets you append `?silent=true` to a link
to have it excluded from:
1. Notifications - users will not be notified for these links
2. Post links below posts in the UI
This is specifically useful for large reports where adding all these connections
just results in noise.
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.
https://meta.discourse.org/t/287211
We want to exclude the system user from group user counts, since intuitively admins wouldn't include them.
Originally this was accomplished by booting said system user from the groups, but this is causing problems, because the system user needs TL group membership to perform certain tasks.
After this PR, system user is still in the TL groups, but excluded when refreshing the user count.
Some preparatory refactoring as we're working on TL groups for the system user. On User we have a scope #human_users to exclude the system user, DiscoBot, etc. This PR adds the same scope (delegated to User) on Group.
We added support for radar type charts in #24274. However, radar charts work with three variables, meaning we can't display any report that way.
Unfortunately, by adding `:radar` to the `Report#modes` variable, I made them widely available.
Related bug report: https://meta.discourse.org/t/report-radar-graph-uncaught-typeerror/292360
This is a temporary fix to address an issue where the
system user is losing its automatic groups when the server
is running. If any auto groups are provided, and the user is
a system user, then we return true. The system user is admin,
moderator, and TL4, so they usually have all auto groups.
We can remove this when we get to the bottom of why the auto
groups are being deleted.
The old strategy used to load 25 categories at a time, including the
subcategories. The new strategy loads 20 parent categories and at most
5 subcategories for each parent category, for a maximum of 120
categories in total.
- 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?
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.
Why this change?
We have been chasing a problem with our flaky system test where the user
is logged out when it should never be.
What does this change do?
1. Logs the request path when lookup a user auth token.
2. Logs the request path and also the current thread's object id in
ActiveRecord query logs.
* FIX: respect creation date when paginating group activity posts
There are scenarios where the chronological order of posts doesn't match the order of their IDs. For instance, when moving the first post from one topic or PM to another, a new post (with a higher ID) will be created, but it will retain the original creation time.
This PR changes the group activity page and endpoint to paginate posts using created_at instead of relying on ID ordering.
Why this change?
Importing theme with the `bundle` params is used mainly by
`discourse_theme` CLI in the development environment. However, we do not
want migrations to automatically run in the development environment
and instead want the developer to be intentional about running theme
migrations. As such, this commit adds support for a
`skip_migrations` param when importing a theme with the `bundle` params.
This commit also adds a `migrated` attribute for migrations theme fields
to indicate whether a migrations theme field has been migrated or not.
The query that is now a subquery could return a long list of category
IDs, which slowed down the query considerably. This improvement reduces
the execution time from over 2 seconds down to about 100ms.

I ran out of time to get this working for that fix,
also here I am making the post.url method have parity
with post.shareUrl in JS, which omits the post number
for the first post.
Currently, the reviewable queue includes ReviewableFlaggedPost with posts that have already been hidden. This allows for such hidden posts to be cleared up by the auto-tool.
Categories will no longer be preloaded when `lazy_load_categories` is
enabled through PreloadStore.
Instead, the list of site categories will continue to be populated
by `Site.updateCategory` as more and more categories are being loaded
from different sources (topic lists, category selectors, etc).
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.
When updating the position of a category, the server correctly updates the position in the database, but the response sent back to the client still contains the old position, causing it to "flip back" in the UI when saving. Only reloading the page will reveal the new, correct value.
The Positionable concern correctly positions the record and updates the database, but we don't assign the new position to the already instantiated model.
This change just assigns self.position after the database update. 😎
Adds an API scope for accessing Logster's routes. This one is a bit
different than routes from core because it is mounted like
```
mount Logster::Web => "/logs"
```
and doesn't have all the route info a traditional rails app/engine does.
Settings that are using the new `file_size_restriction` types like the
`max_image_size_kb` setting need to have their values saved as integers.
This was a recent regression in 00209f03e6
that caused these values to be saved as strings.
This change also removes negatives from the validation regex because
file sizes can't be negative anyways.
Bug report: https://meta.discourse.org/t/289037
This commit refactor CategoryList to remove usage of EmberObject,
hopefully make the code more readable and fixes various edge cases with
lazy loaded categories (third level subcategories not being visible,
subcategories not being visible on category page, requesting for more
pages even if the last one did not return any results, etc).
The problems have always been here, but were not visible because a lot
of the processing was handled by the server and then the result was
serialized. With more of these being moved to the client side for the
lazy category loading, the problems became more obvious.
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.
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_edit_post site setting to edit_post_allowed_groups.
The old implementation will co-exist for a short period while I update any references in plugins and themes.
Applies the embed_unlisted site setting consistently across topic embeds, including those created via the WP Discourse plugin. Relatedly, adds a embed exception to can_create_unlisted_topic? check. Users creating embedded topics are not always staff.
When `lazy_load_categories` is enabled, the categories are no longer
preloaded in the `Site` object, but instead they are being requested
on a need basis.
The categories page still loaded all categories at once, which was not
ideal for sites with many categories because ti would take a lot of
time to build and parse the response.
This commit adds pagination to the categories page using the LoadMore
helper. As the user scrolls through the categories page, more categories
are requested from the server and appended to the page.
<!-- NOTE: All pull requests should have tests (rspec in Ruby, qunit in JavaScript). If your code does not include test coverage, please include an explanation of why it was omitted. -->
This script preprocesses all uploads within a intermediate DB (output of converters) and uploads those files to S3. It does the same for optimized images. This speeds up migrations when you have to run them multiple times, because you only have to preprocess and upload the files once.
This script is very hacky and mostly undocumented for now. That will change in the future.
A lot of work has been put in the select kits used for selecting
categories: CategorySelector, CategoryChooser, CategoryDrop, however
they still do not work as expected when these selectors already have
values set, because the category were still looked up in the list of
categories stored on the client-side Categrories.list().
This PR fixes that by looking up the categories when the selector is
initialized. This required altering the /categories/find.json endpoint
to accept a list of IDs that need to be looked up. The API is called
using Category.asyncFindByIds on the client-side.
CategorySelector was also updated to receive a list of category IDs as
attribute, instead of the list of categories, because the list of
categories may have not been loaded.
During this development, I noticed that SiteCategorySerializer did not
serializer all fields (such as permission and notification_level)
which are not a property of category, but a property of the relationship
between users and categories. To make this more efficient, the
preload_user_fields! method was implemented that can be used to
preload these attributes for a user and a list of categories.
When rebaking and in various other places for posts, we
run through the uploads and call `update_secure_status` on
each of them.
However, if the secure status didn't change, we were still
calling S3 to change the ACL, which would have been a noop
in many cases and takes ~1 second per call, slowing things
down a lot.
Also, we didn't account for the s3_acls_enabled site setting
being false here, and in the specs doing an assertion
that `Discourse.store.update_ACL` is not called doesn't
work; `Discourse.store` isn't a singleton, it re-initializes
`FileStore::S3Store.new` every single time.
The category drop was rerendered after every category async change
because it updated the categories list. This is not necessary and
categories can be referenced indirectly by ID instead.
This value is included when generating static asset URLs. Updating the value will allow site operators to invalidate all asset urls to recover from configuration issues which may have been cached by CDNs/browsers.
When we check upload security, one of the checks is to
run `access_control_post.with_secure_uploads?`. The problem
here is that the `topic` for the post could be deleted,
which would make the check return `nil` sometimes instead
of false because of safe navigation. We just need to be
more explicit.
Admin can add tag description up to 1000 characters.
Full description is displayed on tag page, however on topic list it is truncated to 80 characters.

We introduced video placeholders which prevent preloading
metadata for videos in posts. The structure looks like this
in HTML when the post is cooked:
```
<div class="video-placeholder-container" data-video-src="http://some-url.com/video.mp4" dir="ltr" style="cursor: pointer;">
<div class="video-placeholder-wrapper">
<div class="video-placeholder-overlay">
<svg class="fa d-icon d-icon-play svg-icon svg-string" xmlns="http://www.w3.org/2000/svg">
<use href="#play"></use>
</svg>
</div>
</div>
</div>
```
However, we did not update the code that links post uploads
to the post via UploadReference, so any videos uploaded since
this change are essentially dangling and liable to be deleted.
This also causes some uploads to be marked secure when they
shouldn't be, because they are not picked up and analysed in the
CookedPostProcessor flow.
The parent category needs to be serialized before the child category
because they are parsed in order. Otherwise the client will not build
the parent-child relationship correctly.
Operate a key at a time, to make it clearer what's going on.
This also fixes a bug where array integer fields would get re-written
even when there wasn't a change.
Array custom fields use separate rows for each value, but whenever we
update an array, we have always destroy the existing rows and create new
ones. Therefore, there's no benefit over using the json type.
This commit adds a new `search_default_sort_order` site setting,
set to "relevance" by default, that controls the default sort order
for the full page /search route.
If the user changes the order in the dropdown on that page, we remember
their preference automatically, and it takes precedence over the site
setting as a default from then on. This way people who prefer e.g.
Latest Post as their default can make it so.
en is the only fallback locale we use, so there's no need to invalidate everything when other languages change. Limiting this also helps to prevent circular dependent_field relations which could cause issues in some situations.

Why this change?
As the number of themes which the Discourse team supports officially
grows, we want to ensure that changes made to Discourse core do not
break the plugins. As such, we are adding a step to our Github actions
test job to run the QUnit tests for all official themes.
What does this change do?
This change adds a new job to our tests Github actions workflow to run the QUnit
tests for all official plugins. This is achieved with the following
changes:
1. Update `testem.js` to rely on the `THEME_TEST_PAGES` env variable to set the
`test_page` option when running theme QUnit tests with testem. The
`test_page` option [allows an array to be specified](https://github.com/testem/testem#multiple-test-pages) such that tests for
multiple pages can be run at the same time. We are relying on a ENV variable
because the `testem` CLI does not support passing a list of pages
to the `--test_page` option.
2. Support a `/testem-theme-qunit/:testem_id/theme-qunit` Rails route in the development environment. This
is done because testem prefixes the path with a unique ID to the configured `test_page` URL.
This is problematic for us because we proxy all testem requests to the
Rails server and testem's proxy configuration option does not allow us
to easily rewrite the URL to remove the prefix. Therefore, we configure a proxy in testem to prefix `theme-qunit` requests with
`/testem-theme-qunit` which can then be easily identified by the Rails server and routed accordingly.
3. Update `qunit:test` to support a `THEME_IDS` environment variable
which will allow it to run QUnit tests for multiple themes at the
same time.
4. Support `bin/rake themes:qunit[ids,"<theme_id>|<theme_id>"]` to run
the QUnit tests for multiple themes at the same time.
5. Adds a `themes:qunit_all_official` Rake task which runs the QUnit
tests for all the official themes.
Previously we would only recompile a theme locale when its own data changes. However, the output also includes fallback data from other locales, so we need to invalidate all locales when fallback locale data is changed. Building a list of dependent locales is tricky, so let's just invalidate them all.

For consistency with other S3 settings, make the global setting
the same name as the site setting and use SiteSetting.Upload
too so it reads from the correct place.
This adds the ability to collect stats without exposing them
among other stats via API.
The most important thing I wanted to achieve is to provide
an API where stats are not exposed by default, and a developer
has to explicitly specify that they should be
exposed (`expose_via_api: true`). Implementing an opposite
solution would be simpler, but that's less safe in terms of
potential security issues.
When working on this, I had to refactor the current solution.
I would go even further with the refactoring, but the next steps
seem to be going too far in changing the solution we have,
and that would also take more time. Two things that can be
improved in the future:
1. Data structures for holding stats can be further improved
2. Core stats are hard-coded in the About template (it's hard
to fix it without correcting data structures first, see point 1):
63a0700d45/app/views/about/index.html.erb (L61-L101)
The most significant refactorings are:
1. Introducing the `Stat` model
2. Aligning the way the core and the plugin stats' are registered
There was a registry for preloaded site categories and a new one has
been introduced recently for categories serialized through a
CategoryList.
Having two registries created a lot of friction for developers and this
commit merges them into a single one, providing a unified API.
There is an edge case where the following occurs:
1. The user sets a bookmark reminder on a post/topic
2. The post/topic is changed to a PM before or after the reminder
fires, and the notification remains unread by the user
3. The user opens their bookmark reminder notification list
and they can still see the notification even though they cannot
access the topic anymore
There is a very low chance for information leaking here, since
the only thing that could be exposed is the topic title if it
changes to something sensitive.
This commit filters the bookmark unread notifications by using
the bookmarkable can_see? methods and also prevents sending
reminder notifications for bookmarks the user can no longer see.
When quoting a chat message in a post, if that message contains a mention,
that mention should be ignored. But we've been detecting them and sending
notifications to users. This PR fixes the problem. Since this fix is for
the chat plugin, I had to introduce a new API for plugins:
# We strip posts before detecting mentions, oneboxes, attachments etc.
# We strip those elements that shouldn't be detected. For example,
# a mention inside a quote should be ignored, so we strip it off.
# Using this API plugins can register their own post strippers.
def register_post_stripper(&block)
end
We updated scheduled admin checks to run concurrently in their own jobs. The main reason for this was so that we can implement re-check functionality for especially flaky checks (e.g. group e-mail credentials check.)
This works in the following way:
1. The check declares its retry policy using class methods.
2. A block can be yielded to if there are problems, but before they are committed to Redis.
3. The job uses this block to either a) schedule a retry if there are any remaining or b) do nothing and let the check commit.
This PR does some preparatory refactoring of scheduled admin checks in order for us to be able to do custom retry strategies for some of them.
Instead of running all checks in sequence inside a single, scheduled job, the scheduled job spawns one new job per check.
In order to be concurrency-safe, we need to change the existing Redis data structure from a string (of serialized JSON) to a list of strings (of serialized JSON).
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
The User#flag_level column has not been in use for a very long time. The "new" reviewable system dynamically calculates flag scores based on past performance of the user.
This PR removes flag_level from the admin user serializer (since it isn't displayed anywhere in admin user lists) and marks the column as deprecated and targeted for removal in the next minor version.
The message: :signup_not_allowed option to the IP address validator does nothing, because the AllowedIpAddressValidator chooses one of either:
- ip_address.blocked or
- ip_address.max_new_accounts_per_registration_ip
internally. This means that the translation for this was also never used.
This PR removes the ineffectual option and the unused translation. It also moves the translated error messages for blocked and max_new_accounts_per_registration_ip into the correct location so we can pass a symbol to ActiveModel::Errors#add.
There is no actual change in behaviour.
Followup to 9762e65758. This
original commit did not take into account the fact that
new topics can end up in the approval queue as a
ReviewableQueuedPost, and so there was a 500 error raised
when accessing `self.topic` when sending a PM to the user.
Using SiteSetting.queue_jobs= to configure job asynchronicity was deprecated here four years ago and marked for removal in version 2.9.0. This PR removes the fallback method we kept since then. The method was there because it was still being used in a bunch of plugin tests (now fixed.)
The PostAction.remove_act class method has been deprecated and replaced by PostActionDestroyer. It was marked for removal in version 2.9.0. This PR removes the method.
Why this change?
Currently, we do not have a method to easily retrieve a theme setting's
value on the server side. Such a method can be useful in the test
environment where we need to retrieve the theme's setting and use its
value in assertions.
What does this change do?
This change introduces the `Theme#get_setting` instance method.
This change adds a new event trigger (new_post_moved) when the first post in a topic is moved to a new topic.
Plugins that listen for the new_post_moved event now have an easy way to update old data based on the post id.
There are a few PUT requests that users can do in their preferences tab that aren't going through the standard `user#update` action.
This commit adds all the "trivial" ones (aka. except the security-related one, username and email changes) so you can now change the badge title, the avatar or featured topic of a user via the API.
This commit adds a new admin UI under the route `/admin-revamp`, which is
only accessible if the user is in a group defined by the new `enable_experimental_admin_ui_groups` site setting. It
also adds a special `admin` sidebar panel that is shown instead of the `main`
forum one when the admin is in this area.
We also add an "Admin Revamp" sidebar link to the community section, which
will only appear if the user is in the setting group:
Within this there are subroutes defined like `/admin-revamp/config/:area`,
these areas could contain any UI imaginable, this is just laying down an
initial idea of the structure and how the sidebar will work. Sidebar links are
currently hardcoded.
Some other changes:
* Changed the `main` and `chat` panels sidebar panel keys to use exported const values for reuse
* Allowed custom sidebar sections to hide their headers with the `hideSectionHeader` option
* Add a `groupSettingArray` setting on `this.siteSettings` in JS, which accepts a group site setting name
and splits it by `|` then converts the items in the array to integers, similar to the `_map` magic for ruby
group site settings
* Adds a `hidden` option for sidebar panels which prevents them from showing in separated mode and prevents
the switch button from being shown

* 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 reverts commit 5f0bc4557f.
Through extensive internal discussion we have decided to revert
this change, as it significantly impacted moderation flow for
some Discourse site moderators, especially around "something else"
flags. We need to re-approach how flags are counted holistically,
so to that end this change is being reverted.
Site data is preloaded on the first page load, which includes categories
data. For sites with many categories, site data takes a long time to
serialize and to transfer.
In the future, preloaded category data will be completely removed.
The category style site setting is being deprecated. This commit will
show a warning on the admin dashboard if a site isn't using the default
category style (bullet).
At this moment, this feature is under a site setting named
lazy_load_categories.
In the future, categories will no longer be preloaded through site data.
This commit add information about categories in topic list and ensures
that data is used to display topic list items.
Parent categories are serialized too because they are necessary to
render {{category-link}}.
There are cases where a user can copy image markdown from a public
post (such as via the discourse-templates plugin) into a PM which
is then sent via an email. Since a PM is a secure context (via the
.with_secure_uploads? check on Post), the image will get a secure
URL in the PM post even though the backing upload is not secure.
This fixes the bug in that case where the image would be stripped
from the email (since it had a /secure-uploads/ URL) but not re-attached
further down the line using the secure_uploads_allow_embed_images_in_emails
setting because the upload itself was not secure.
The flow in Email::Sender for doing this is still not ideal, but
there are chicken and egg problems around when to strip the images,
how to fit in with other attachments and email size limits, and
when to apply the images inline via Email::Styles. It's convoluted,
but at least this fixes the Template use case for now.
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.
We run the ember-this-fallback transformation on plugin and theme code so that they can continue omitting `this.` in `.hbs` templates. A bug in the implementation meant that it was incorrectly transforming things like `{{dir/some-component}}` into `<DirSomeComponent />` (rather than `<Dir::SomeComponent />`).
This commit uses patch-package to apply the fix from https://github.com/tildeio/ember-this-fallback/pull/56
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.
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.

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).
Meta topic: https://meta.discourse.org/t/suppress-these-tags-from-summary-emails-settings-is-not-working-in-preview-digest-email/279196?u=osama
Follow-up to 477a5dd371
The `digest_suppress_tags` setting is designed to be a list of pipe-delimited tag names, but the tag-based topic suppression logic assumes (incorrectly) that the setting contains pipe-delimited tag IDs. This mismatch in expectations led to the setting not working as expected.
This PR adds a step that converts the list of tag names in the setting to their corresponding IDs, which is then used to suppress topics tagged with those specific tags.
This commit adds limits to themes and theme components on the:
- file size of about.json and .discourse-compatibility
- file size of theme assets
- number of files in a theme
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.
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.
This adds a new secure_uploads_pm_only site setting. When secure_uploads
is true with this setting, only uploads created in PMs will be marked
secure; no uploads in secure categories will be marked as secure, and
the login_required site setting has no bearing on upload security
either.
This is meant to be a stopgap solution to prevent secure uploads
in a single place (private messages) for sensitive admin data exports.
Ideally we would want a more comprehensive way of saying that certain
upload types get secured which is a hybrid/mixed mode secure uploads,
but for now this will do the trick.
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.
Follow-up to #23199 in which we moved the "delete user" options under the relevant action menu for flagged post. This change does the same, but to queued posts.
As per discussion, we want to move the options to delete the user under the "Yes" menu of the review queue, since these options are often the most recommended, but also frequently missed because they are tucked away under their own menu.
In addition to the move, I removed the title case of the options so that it matches the other options in the "Yes" menu.
Reverts e2705df and re-lands #23187 and #23219.
The issue was incorrect order of execution of Rails' `assets:precompile` task in our own precompilation stack.

Manipulating theme module paths means that the paths you author are not the ones used at runtime. This can lead to some very unexpected behavior and potential module name clashes. It also meant that the refactor in 16c6ab8661 was unable to correctly match up theme connector js/templates.
While this could technically be a breaking change, I think it is reasonably safe because:
1. Themes are already forced to use relative paths when referencing their own modules (since they're namespaced based on the site-specific id). The only time this might be problematic is when theme tests reference modules in the theme's main `javascripts` directory
2. For things like components/services/controllers/etc. our custom Ember resolver works backwards from the end of the path, so adding `discourse/` in the middle will not affect resolution.
This is a bug that happens only when the current date is less than 90 days from a date on which the time zone transitions into or out of Daylight Savings Time.
In these conditions, bulk invites show the time of day of their expiration as being 1 hour later than the current time.
Whereas it should match the time of day the invite was generated.
This is because the server has not been using the user's timezone in calculating the expiration time of day. This PR fixes issue by considering the user's timezone when doing the date math.
https://meta.discourse.org/t/bulk-invite-logic-to-generate-expire-date-bug/274689
`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.
Previously we were discovering plugin outlets by checking first for dedicated template files, and then looking for classes to match them. This doesn't work for components which are entirely defined in JS (e.g. those authored with gjs, or those which are re-exports of a colocated component).
This commit refactors our detection logic to look for both class and template modules in a single pass. It also refactors things so that the modules themselves are required lazily when needd, rather than all being loaded during app boot.
When hiding a post (essentially updating hidden, hidden_at, and hidden_reason_id) our callbacks are running the whole battery of post validations. This can cause the hiding to fail in a number of edge cases. The issue is similar to the one fixed in #11680, but applies to all post validations, none of which should apply when hiding a post.
After some code reading and discussion, none of the validations in PostValidator seem to be relevant when hiding posts, so instead of just skipping unique check, we skip all post validator checks.

Currently when we decide we're going to drop a column in the future we just mark it with a TODO comment and add it to ignored_columns. This makes it instantly unavailable, and we mostly forget about the TODO in the end. 😬
This change adds a HasDeprecatedColumns concern which offers a little bit more flexibility. We can still simulate the old behaviour by setting drop_from to the current version, but we can also set it to a future version, causing it to raise a deprecation warning until then if used.
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.
This brings the theme development experience (via the discourse_theme cli) closer to the experience of making javascript changes in Discourse core/plugins via Ember CLI. Whenever a change is made to a non-css theme field, all clients will be instructed to immediately refresh via message-bus.
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.
* FIX Add 'Ignored' flags to Moderator Activity report

FEATURE: Only approved flags for post counters
* Why was this change necessary?
The counters for flagged posts in the user's profile and user index from
the admin view include flags that were rejected, ignored or pending
review. This introduces unnecessary noise. Also the flagged posts
counter in the user's profile includes custom flags which add further
noise to this signal.
* How does it address the problem?
* Modifying User#flags_received_count to return posts with only approved
standard flags
* Refactoring User#number_of_flagged_posts to alias to
User#flags_received_count
* Updating the flagged post staff counter hyperlink to navigate to a
filtered view of that user's approved flagged posts to maintain
consistency with the counter
* Adding system tests for the profile page to cover the flagged posts
staff counter
In the query generated by `TopicTrackingState.report`, there are two
subqueies being executed. The first subquery fetches all the topics
that are new for a given user while the second subquery fetches all the topics with
unread posts for a given user. For the second subquery, there is a
filter `topics.updated_at >= user_stats.first_unread_at` which is used
as a performance optimisation to reduce the number of rows that PG has
to scan through the `topics` table.
However, we started to notice in production that the PG planner doesn't
always execute the filter first to reduce the number of rows that it has
to scan through. Running the following query in one of our production
instance,

From the execution plan, we can see the most of the time is spent
joining about 42888 rows in the `topics` table to the `topic_users` table.
However, we know that we only have to scan through a
subset of the `topics` table because the user's last unread at is '2023-07-20 11:33:05'.
If we filter the `topics` table with `topics.updated_at >= '2023-07-20 11:33:05'`, this would only
return about 1500 rows.
From our testing in production, the PG planner is able to execute a
better query plan when we avoid the unnecessary joins on `user_stats` just to be
able to get the user's `UserStat#first_unread_at`. Instead, we can just
pass the value of `UserStat#first_unread_at` directly as a query
parameter.

With the new query, PG first does an index scan using the `index_topics_on_updated_at_public` index to filter away most of the topics making the subsequent joins much cheaper. Total query time has been reduced from ~90ms to ~5ms.
This optimisation will mostly affect users with very few/recent unread topics since a large `UserStat#firsts_unread_at` value will still mean scanning through a large portion of the `topics` table.
We currently are accumulating orphaned upload references whenever drafts are deleted.
This change deals with future cases by adding a dependent strategy of delete_all on the Draft#upload_references association. (We don't really need destroy strategy here, since UploadReference is a simple data bag and there are no validations or callbacks on the model.)
It deals with existing cases through a migration that deletes all existing, orphaned draft upload references.
A previous change updated `ReviewableQueuedPost`'s `created_by`
to be consistent with other reviewable types. It assigns
the the creator of the post being queued to `target_created_by` and sets
the `created_by` to the creator of the reviewable itself.
This fix updates some of the `created_by` references missed during the
intial fix.
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.
This is happening because despite the user already existing in the forum, the `SingleSignOnRecord` doesn't exist and "require_activation" is set on the provider, causing us to skip looking for the email, and resulting in us creating a new User then seeing Validation failed: Primary email has already been taken when DiscourseConnect is attempting to make a new account.
