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`.
### What is the problem?
It is possible to pass an arbitrary value to the limit parameter in `TagsController#search`, and have it flow through `DiscourseTagging.filter_allowed_tags` where it will raise an error deep in the database driver. MiniSql ensures there's no injection happening, but that ultimately results in an invalid query.
### How does this fix it?
This change checks more strictly that the parameter can be cleanly converted to an integer by replacing the loose `#to_i` conversion semantics with the stronger `Kernel#Integer` ones.
**Example:**
```ruby
"1; SELECT 1".to_i
#=> 1
Integer("1; SELECT 1")
#=> ArgumentError
```
As part of the change, I also went ahead to disallow a limit of "0", as that doesn't seem to be a useful option. Previously only negative limits were disallowed.
* DEV: move sidebar community section to database
Before, community section was hard-coded. In the future, we are planning to allow admins to edit it. Therefore, it has to be moved to database to `custom_sections` table.
Few steps and simplifications has to be made:
- custom section was hidden behind `enable_custom_sidebar_sections` feature flag. It has to be deleted so all forums, see community section;
- migration to add `section_type` column to sidebar section to show it is a special type;
- migration to add `segment` column to sidebar links to determine if link should be displayed in primary section or in more section;
- simplify more section to have one level only (secondary section links are merged);
- ensure that links like `everything` are correctly tracking state;
- make user an anonymous links position consistence. For example, from now on `faq` link for user and anonymous is visible in more tab;
- delete old community-section template.
We are seeing issues with the composer not being able to close due to the addition of a error message when rescuing from `Draft::OutOfSequence`. This PR will revert to the original solution implemented prior to https://github.com/discourse/discourse/pull/21148 that just silently rescues from `Draft::OutOfSequence`
This PR adds the ability to destroy reviewables for a passed user via the API. This was not possible before as this action was reserved for reviewables for you created only.
If a user is an admin and calls the `#destroy` action from the API they are able to destroy a reviewable for a passed user. A user can be targeted by passed either their:
- username
- external_id (for SSO)
to the request.
In the case you attempt to destroy a non-personal reviewable and
- You are not an admin
- You do not access the `#destroy` action via the API
you will raise a `Discourse::InvalidAccess` (403) and will not succeed in destroying the reviewable.

* FEATURE: add a setting to allowlist DiscourseConnect return path domains
This commit adds a site setting to allowlist DiscourseConnect return
path domains. The setting needs supports exact domain or wildcard
character (*) to allow for any domain as return path.
* Add more specs to clarify what is allowed in site setting
* Update setting description to explain what is allowed
Previously, public custom sections were only visible to logged-in users. In this PR, we are making them visible to anonymous as well.
The reason is that Community Section will be moved into custom section model to be easily editable by admins.
The following are the changes being introduced in this commit:
1. Instead of mapping the query language to various query params on the
client side, we've decided that the benefits of having a more robust
query language far outweighs the benefits of having a more human readable query params in the URL.
As such, the `/filter` route will just accept a single `q` query param
and the query string will be parsed on the server side.
1. On the `/filter` route, the tags filtering query language is now
supported in the input per the example provided below:
```
tags:bug+feature tagged both bug and feature
tags:bug,feature tagged either bug or feature
-tags:bug+feature excluding topics tagged bug and feature
-tags:bug,feature excluding topics tagged bug or feature
```
The `tags` filter can also be specified multiple
times in the query string like so `tags:bug tags:feature` which will
filter topics that contain both the `bug` tag and `feature` tag. More
complex query like `tags:bug+feature -tags:experimental` will also work.
This corrects two issues:
1. We were double serializing topic tracking state (as_json calls were not cached)
2. We were inefficiently serializing items by instantiating extra objects
Why is this change required?
Prior to this change, we would list all group messages that a user
has access to in the user menu messages notifications panel dropdown.
However, this did not respect the topic's notification level setting and
group messages which the user has set to 'normal' notification level were
being displayed
What does this commit do?
With this commit, we no longer display all group messages that a user
has access to. Instead, we only display group messages that a user is
watching in the user menu messages notifications panel dropdown.

Currently the auto-bump cooldown is hard-coded to 24 hours.
This change makes the highlighted 24 hours part configurable (defaulting to 24 hours), and the rest of the process remains the same.
This uses the new CategorySetting model associated with Category. We decided to add this because we want to move away from custom fields due to the lack of type casting and validations, but we want to keep the loading of these optional as they are not needed for almost all of the flows.
Category settings will be back-filled to all categories as part of this change, and creating a new category will now also create a category setting.
This commit implements many changes to topic and comments embedding. It
deprecates the class_name field from EmbeddableHost and suggests using
the className parameter. discourse_username parameter has been
deprecated and it will fetch it from embedded site from the author or
discourse-username meta.
See the updated code sample from Admin > Customize > Embedding page.
* FEATURE: Add className parameter for Discourse embed
* DEV: Hide class_name from EmbeddableHost
* DEV: Deprecate class_name field of EmbeddableHost

* DEV: Improve embed code sample
What does this change do?
This commit the client to override the navigation menu setting
configured by the site temporarily based on the value of the
`navigation_menu` query param. The new query param replaces the old
`enable_sidebar` query param.
Why do we need this change?
The motivation here is to allow theme maintainers to quickly preview
what the site will look like with the various navigation menu site
setting.
Previously, a user avatar redirect had a lifetime of 24h. That means that a change to the S3 CDN URL would take up to 24h to propagate to clients and intermediate CDNs.
This commit reduces the max age to 1 hour, but also introduces a `stale-while-revalidate` directive. This allows clients and CDNs to use a 'stale' value if it was received between 1h and 24h ago, as long as they make a background request to update the cache. This should reduce the impact of S3 URL changes. 1 hour after the change, the CDN will start serving updated values. Plus, if users have cached bad responses, their browser will automatically fetch the correct version and use it on the next page load.
The #pluck_first freedom patch, first introduced by @danielwaterworth has served us well, and is used widely throughout both core and plugins. It seems to have been a common enough use case that Rails 6 introduced it's own method #pick with the exact same implementation. This allows us to retire the freedom patch and switch over to the built-in ActiveRecord method.
There is no replacement for #pluck_first!, but a quick search shows we are using this in a very limited capacity, and in some cases incorrectly (by assuming a nil return rather than an exception), which can quite easily be replaced with #pick plus some extra handling.
When a post is created using the API and goes into the review queue, we
would return a 'null' string in the response which isn't valid JSON.

- [x] "+ save" renamed to just "save"
- [x] Render emojis in link name
- [x] UI to set icon
- [x] Delete link is trash icon instead of "x"
- [x] Add another link to on the left and rewording
- [x] Raname "link name" -> "name", "points to" -> link
- [x] Add limits to fields
- [x] Move add section button to the bottom
Allows users to configure their own custom sidebar sections with links withing Discourse instance. Links can be passed as relative path, for example "/tags" or full URL.
Only path is saved in DB, so when Discourse domain is changed, links will be still valid.
Feature is hidden behind SiteSetting.enable_custom_sidebar_sections. This hidden setting determines the group which members have access to this new feature.
1. What is the problem here?
When a user's reviewables count changes, the changes are published via
MessageBus in a background Sidekiq job which means there is a delay before the
client receives the MessageBus message with the updated count. During
the time the reviewables count for a user has been updated and the time
when the client receives the MessageBus message with the updated count,
a user may view the reviewables list in the user menu. When that happens, the number of
reviewables in the list may be out of sync with the count shown.
2. What is the fix?
Going forward, the response for the `ReviewablesController#user_menu_list` action will include the user's reviewables count as
the `reviewables_count` attribute. This is then used by the client side
to update the user's reviewables count to ensure that the reviewables
list and count are kept in sync.
## Why do we need this change?
When loading the ember app, [MessageBus does not start polling immediately](f31f0b70f8/app/assets/javascripts/discourse/app/initializers/message-bus.js (L71-L81)) and instead waits for `document.readyState` to be `complete`. What this means is that if there are new messages being created while we have yet to start polling, those messages will not be received by the client.
With sidebar being the default navigation menu, the counts derived from `topic-tracking-state.js` on the client side is prominently displayed on every page. Therefore, we want to ensure that we are not dropping any messages on the channels that `topic-tracking-state.js` subscribes to.
## What does this change do?
This includes the `MessageBus.last_id`s for the MessageBus channels which `topic-tracking-state.js` subscribes to as part of the preloaded data when loading a page. The last ids are then used when we subscribe the MessageBus channels so that messages which are published before MessageBus starts polling will not be missed.
## Review Notes
1. See https://github.com/discourse/message_bus#client-support for documentation about subscribing from a given message id.
Currently `Topic#pm_topic_count` is a count of all personal messages tagged for a given tag. As a result, any user with access to PM tags can poll a sensitive tag to determine if a new personal message has been created using that tag even if the user does not have access to the personal message. We classify this as a minor leak in sensitive information.
With this commit, `Topic#pm_topic_count` is hidden from users by default unless the `display_personal_messages_tag_counts` site setting is enabled.
A while back the definition of TL was changed but many
areas in the codebase still use the term 'Regular user'
despite it having some implicit meaning (TL2).
See 20140905055251_rename_trust_level_badges.rb
When the `tags_listed_by_group` site setting is disable, we were seeing
the N+1 queries problem when multiple `CategoryTag` records are listed.
This commit fixes that by ensuring that we are not filtering through the
category `tags` association after the association has been eager loaded.
* FIX: Ensure soft-deleted topics can be deleted
The topic was not found during the deletion process because it was
deleted and `@post.topic` was nil.
* DEV: Use @topic instead of finding the topic every time
This commit allows us to set the channel slug when creating new chat
channels. As well as this, it introduces a new `SlugsController` which can
generate a slug using `Slug.for` and a name string for input. We call this
after the user finishes typing the channel name (debounced) and fill in
the autogenerated slug in the background, and update the slug input
placeholder.
This autogenerated slug is used by default, but if the user writes anything
else in the input it will be used instead.
Currently, `Tag#topic_count` is a count of all regular topics regardless of whether the topic is in a read restricted category or not. As a result, any users can technically poll a sensitive tag to determine if a new topic is created in a category which the user has not excess to. We classify this as a minor leak in sensitive information.
The following changes are introduced in this commit:
1. Introduce `Tag#public_topic_count` which only count topics which have been tagged with a given tag in public categories.
2. Rename `Tag#topic_count` to `Tag#staff_topic_count` which counts the same way as `Tag#topic_count`. In other words, it counts all topics tagged with a given tag regardless of the category the topic is in. The rename is also done so that we indicate that this column contains sensitive information.
3. Change all previous spots which relied on `Topic#topic_count` to rely on `Tag.topic_column_count(guardian)` which will return the right "topic count" column to use based on the current scope.
4. Introduce `SiteSetting.include_secure_categories_in_tag_counts` site setting to allow site administrators to always display the tag topics count using `Tag#staff_topic_count` instead.
Our JS files reference sourcemaps relative to their current path. On sites with non-S3 CDN setups, we use a special path for brotli assets (39a524aa). This caused the sourcemap requests to 404.
This commit fixes the issue by allowing the `.map` files to be accessed under `/brotli_asset/*`.
When the `tags_listed_by_group` site setting is enabled, we were seeing
the N+1 queries problem when multiple `TagGroup` records are listed.
This commit fixes that by ensuring that we are not filtering through the
`tags` association after the association has been eager loaded.
This is a very subtle one. Setting the redirect URL is done by passing
a hash through a Discourse event. This is broken on Ruby 2 since the
support for keyword arguments in events was added.
In Ruby 2 the last argument is cast to keyword arguments if it is a
hash. The key point here is that creates a new copy of the hash, so
what the plugin is modifying is not the hash that was passed.
In "GlobalSetting.redirect_avatar_requests" mode, when the application gets
an avatar request it returns a "redirect" to the S3 CDN.
This shields the application from caching avatars and downloading from S3.
However clients will make 2 requests per avatar. (one to get redirect,
second to get avatar)
A one hour cache on a redirect means there may be an increase in CDN
traffic, given more clients will ask for the redirect every hour.
This may also lead to an increase in origin requests to the application.
To mitigate lets cache the CDN URL for 1 day.
The downside is that any changes to S3 CDN need extra care to allow for
the extra 1 day delay. (leave data around for 1 extra day)
Previously, calling `sign_in` would cause the browser to be redirected to `/`, and would cause the Ember app to boot. We would then call `visit()`, causing the app to boot for a second time.
This commit adds a `redirect=false` option to the `/session/username/become` route. This avoids the unnecessary boot of the app, and leads to significantly faster system spec run times.
In local testing, this takes the full system-spec suite for chat from ~6min to ~4min.
We were changing the user's user_option.bookmark_auto_delete_preference
to whatever they changed it to in the bookmark modal to use as default
for future bookmarks. However this was leading to a lot of confusion
since if you wanted to set it for one bookmark you had to remember to
change it back on the next one.
This commit removes that automatic functionality, and instead moves
the bookmark auto delete preference to User Preferences > Interface
in an explicit dropdown.
This commit adds a new notification that gets sent to admins when the site gets new features after an upgrade/deploy. Clicking on the notification takes the admin to the admin dashboard at `/admin` where they can see the new features under the "New Features" section.

* FEATURE: Show similar users when penalizing a user
Moderators will be notified if other users with the same IP address
exist before penalizing a user.
* FEATURE: Allow staff to penalize multiple users
This allows staff members to suspend or silence multiple users belonging
to the same person.
This commit allows us to type # in the UI and present autocomplete
results immediately with the following logic for the topic composer,
and reversed for the chat composer:
* Categories the user can access and has not muted sorted by `topic_count`
* Tags the user can access and has not muted sorted by `topic_count`
* Chat channels the user is a member of sorted by `messages_count`
So in effect, we allow searching for hashtags without a search term.
To do this we add a new `search_without_term` to each data source so
each one can define how it wants to handle this logic.
This new site setting replaces the
`enable_experimental_sidebar_hamburger` and `enable_sidebar` site
settings as the sidebar feature exits the experimental phase.
Note that we're replacing this without depreciation since the previous
site setting was considered experimental.

A similar warning is displayed when the user cannot be mentioned because
they have not been invited to the topic.

Sometimes users are still notified even if the group that was mentioned
was not invited to the message. This happens because its members were
invited directly or are members of other groups that were invited.

When uploads are stored on S3, by default Discourse will fetch the avatars and proxy them through to the requesting client. This is simple, but it can lead to significant inbound/outbound network load in the hosting environment.
This commit adds an optional redirect_avatar_requests GlobalSetting. When enabled, requests for user avatars will be redirected to the S3 asset instead of being proxied. This adds an extra round-trip for clients, but it should significantly reduce server load. To mitigate that extra round-trip for clients, a CDN with 'follow redirect' capability could be used.
Users who can access the review queue can claim a pending reviewable(s) which means that the claimed reviewable(s) can only be handled by the user who claimed it. Currently, we show claimed reviewables in the user menu, but this can be annoying for other reviewers because they can't do anything about a reviewable claimed by someone. So this PR makes sure that we only show in the user menu reviewables that are claimed by nobody or claimed by the current user.
Internal topic: t/77235.
While load testing our user creation code path in production, we
identified that executing the DB statement to update the `Group#user_count` column within a
transaction is creating a bottleneck for us. This is because the
creation of a user and addition of the user to the relevant groups are
done in a transaction. When we execute the DB statement to update
`Group#user_count` for the relevant group, a row level lock is held
until the transaction completes. This row level lock acts like a global
lock when the server is creating users that will be added to the same
group in quick succession.
Instead of updating the counter cache within a transaction which the
default ActiveRecord `counter_cache` option does, we simply update the
counter cache outside of the committing transaction.

I'm hesitant to call this a performance improvement since claiming a
reviewable is probably rare. However, this commit cuts out two DB
queries each time we have to publish a reviewable claimed message. More
importantly, publishing to groups scales much better than publishing to
users because we esstentially cap the number ids we have to load into
memory.
This adds API scope for the user status. This also adds a get method to the user status controller. We didn't need a dedicated method that returns status before because the server returns status with user objects, but I think we need to provide this method for API clients.
This commit fleshes out and adds functionality for the new `#hashtag` search and
lookup system, still hidden behind the `enable_experimental_hashtag_autocomplete`
feature flag.
**Serverside**
We have two plugin API registration methods that are used to define data sources
(`register_hashtag_data_source`) and hashtag result type priorities depending on
the context (`register_hashtag_type_in_context`). Reading the comments in plugin.rb
should make it clear what these are doing. Reading the `HashtagAutocompleteService`
in full will likely help a lot as well.
Each data source is responsible for providing its own **lookup** and **search**
method that returns hashtag results based on the arguments provided. For example,
the category hashtag data source has to take into account parent categories and
how they relate, and each data source has to define their own icon to use for the
hashtag, and so on.
The `Site` serializer has two new attributes that source data from `HashtagAutocompleteService`.
There is `hashtag_icons` that is just a simple array of all the different icons that
can be used for allowlisting in our markdown pipeline, and there is `hashtag_context_configurations`
that is used to store the type priority orders for each registered context.
When sending emails, we cannot render the SVG icons for hashtags, so
we need to change the HTML hashtags to the normal `#hashtag` text.
**Markdown**
The `hashtag-autocomplete.js` file is where I have added the new `hashtag-autocomplete`
markdown rule, and like all of our rules this is used to cook the raw text on both the clientside
and on the serverside using MiniRacer. Only on the server side do we actually reach out to
the database with the `hashtagLookup` function, on the clientside we just render a plainer
version of the hashtag HTML. Only in the composer preview do we do further lookups based
on this.
This rule is the first one (that I can find) that uses the `currentUser` based on a passed
in `user_id` for guardian checks in markdown rendering code. This is the `last_editor_id`
for both the post and chat message. In some cases we need to cook without a user present,
so the `Discourse.system_user` is used in this case.
**Chat Channels**
This also contains the changes required for chat so that chat channels can be used
as a data source for hashtag searches and lookups. This data source will only be
used when `enable_experimental_hashtag_autocomplete` is `true`, so we don't have
to worry about channel results suddenly turning up.
------
**Known Rough Edges**
- Onebox excerpts will not render the icon svg/use tags, I plan to address that in a follow up PR
- Selecting a hashtag + pressing the Quote button will result in weird behaviour, I plan to address that in a follow up PR
- Mixed hashtag contexts for hashtags without a type suffix will not work correctly, e.g. #ux which is both a category and a channel slug will resolve to a category when used inside a post or within a [chat] transcript in that post. Users can get around this manually by adding the correct suffix, for example ::channel. We may get to this at some point in future
- Icons will not show for the hashtags in emails since SVG support is so terrible in email (this is not likely to be resolved, but still noting for posterity)
- Additional refinements and review fixes wil
