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.

1. The events table had broken styling, making each row overflow
2. It had confusing routes: `/:id` for "edit" and `/:id/events` for "show" (now it's `/:id/edit` and `/:id` respectively)
3. There previously was an unused backend action (`#edit`) - now it is used (and `web_hooks/:id/events` route has been removed)
4. There was outdated/misplaced/duplicated CSS

* 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.

* FEATURE: Show warning if group cannot be mentioned
A similar warning is displayed when the user cannot be mentioned because
they have not been invited to the topic.
* FEATURE: Resolve mentions for new topic
This commit improves several improvements and refactors
/u/is_local_username route to a better /composer/mentions route that
can handle new topics too.
* FEATURE: Show warning if only some are notified
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
* FEATURE: API to update user's discourse connect external id
This adds a special handling of updates to DiscourseConnect external_id
in the general user update API endpoint.
Admins can create, update or delete a user SingleSignOn record using
PUT /u/:username.json
{
"external_ids": {
"discourse_connect": "new-external-id"
}
}
When opening the invite acceptance page when the user
was already logged in, we were still showing the Accept
Invitation prompt even if the user had already redeemed
the invitation and was present in the `InvitedUser` table.
This would lead to errors when the user clicked on the button.
This commit fixes the issue by hiding the Accept Invitation
button and showing an error message instead indicating that
the user had already redeemed the invitation. This only applies
to multi-use invite links.
The problem was reported as a problem with changing theme in user preferences, after saving a new theme the previously set user status was disappearing (https://meta.discourse.org/t/user-status/240335/42). Turned out though that the problem was more wide, changing pretty much any setting in user preferences apart from user status itself led to clearing the status.
This commit adds some protections in InviteRedeemer to ensure that email
can never be nil, which could cause issues with inviting the invited
person to private topics since there was an incorrect inner join.
If the email is nil and the invite is scoped to an email, we just use
that invite.email unconditionally. If a redeeming_user (an existing
user) is passed in when redeeming an email, we use their email to
override the passed in email. Otherwise we just use the passed in
email. We now raise an error after all this if the email is still nil.
This commit also adds some tests to catch the private topic fix, and
some general improvements and comments around the invite code.
This commit also includes a migration to delete TopicAllowedUser records
for users who were mistakenly added to topics as part of the invite
redemption process.
Currently, moderators are able to set primary group for users
irrespective of the of the `moderators_manage_categories_and_groups` site
setting value.
This change updates Guardian implementation to honour it.
This commit fixes the issue where the sub-category topic list was not
loading for new-topic routes. Since we do not need to preload topic
lists for new topic/message routes this commit adds a no-op controller
that prevents topic lists pre loading and at the same time fixes the sub
category topics not loading issue.
Previously, we didn't have a site-wide setting to set the default behavior for user profile visibility and user presence features. But we already have a user preference for that.
* DEV: Add a dedicated Admin::StaffController base controller
The current parent(Admin:AdminController) for all admin-related controllers
uses a filter that allows only staff(admin, moderator) users.
This refactor makes Admin::AdminController filter for only admins as the name suggests and
introduces a base controller dedicated for staff-related endpoints.
* DEV: Set staff-only controllers parent to Admin::StaffController
Refactor staff-only controllers to inherit newly introduced
Admin::StaffController abstract controller. This conveys the
purpose of the parent controller better unlike the previously used parent
controller.

Before this commit, we did not have guardian checks in place to determine if a
topic's title associated with a user badge should be displayed or not.
This means that the topic title of topics with restricted access
could be leaked to anon and users without access if certain conditions
are met. While we will not specify the conditions required, we have internally
assessed that the odds of meeting such conditions are low.
With this commit, we will now apply a guardian check to ensure that the
current user is able to see a topic before the topic's title is included
in the serialized object of a `UserBadge`.
The previous sidebar default tags and categories implementation did not
allow for a user to configure their sidebar to have no categories or
tags. This commit changes how the defaults are applied. When a user is being created,
we create the SidebarSectionLink records based on the `default_sidebar_categories` and
`default_sidebar_tags` site settings. SidebarSectionLink records are
only created for categories and tags which the user has visibility on at
the point of user creation.
With this change, we're also adding the ability for admins to apply
changes to the `default_sidebar_categories` and `default_sidebar_tags`
site settings historically when changing their site setting. When a new
category/tag has been added to the default, the new category/tag will be
added to the sidebar for all users if the admin elects to apply the changes historically.
Like wise when a tag/category is removed, the tag/category will be
removed from the sidebar for all users if the admin elects to apply the
changes historically.

This commit adds a new `/hashtag/search` endpoint and both
relevant JS and ruby plugin APIs to handle plugins adding their
own data sources and priority orders for types of things to search
when `#` is pressed.
A `context` param is added to `setupHashtagAutocomplete` which
a corresponding chat PR https://github.com/discourse/discourse-chat/pull/1302
will now use.
The UI calls `registerHashtagSearchParam` for each context that will
require a `#` search (e.g. the topic composer), for each type of record that
the context needs to search for, as well as a priority order for that type. Core
uses this call to add the `category` and `tag` data sources to the topic composer.
The `register_hashtag_data_source` ruby plugin API call is for plugins to
add a new data source for the hashtag searching endpoint, e.g. discourse-chat
may add a `channel` data source.
This functionality is hidden behind the `enable_experimental_hashtag_autocomplete`
flag, except for the change to `setupHashtagAutocomplete` since only core and
discourse-chat are using that function. Note this PR does **not** include required
changes for hashtag lookup or new styling.
This commit excludes posts from hidden topics from the latest posts and user activity RSS feeds. Additionally, it also excludes small actions from the first one.
Theme javascript is now minified using Terser, just like our core/plugin JS bundles. This reduces the amount of data sent over the network.
This commit also introduces sourcemaps for theme JS. Browser developer tools will now be able show each source file separately when browsing, and also in backtraces.
For theme test JS, the sourcemap is inlined for simplicity. Network load is not a concern for tests.
This commit introduces a new framework for building user tutorials as
popups using the Tippy JS library. Currently, the new framework is used
to replace the old notification spotlight and tips and show a new one
related to the topic timeline.
All popups follow the same structure and have a title, a description and
two buttons for either dismissing just the current tip or all of them
at once.
The state of all seen popups is stored in a user option. Updating
skip_new_user_tips will automatically update the list of seen popups
accordingly.

Experiment moving from preload tags in the document head to preload information the the response headers.
While this is a minor improvement in most browsers (headers are parsed before the response body), this allows smart proxies like Cloudflare to "learn" from those headers and build HTTP 103 Early Hints for subsequent requests to the same URI, which will allow the user agent to download and parse our JS/CSS while we are waiting for the server to generate and stream the HTML response.

This commit adds non-archived group messages and `group_message_summary` notifications in the messages tab in the user menu. With this change, the messages tab in the user menu now includes 3 types of items:

2. Unread and read `group_message_summary` notifications (notifications when there's a new message in a group inbox that you track)
3. Non-archived personal and group messages
Unread `private_message` notifications are always shown first, followed by unread `group_message_summary` notifications, and then everything else (messages and read `group_message_summary` notifications) sorted by recency (most recent first).

This commit renames all secure_media related settings to secure_uploads_* along with the associated functionality.
This is being done because "media" does not really cover it, we aren't just doing this for images and videos etc. but for all uploads in the site.
Additionally, in future we want to secure more types of uploads, and enable a kind of "mixed mode" where some uploads are secure and some are not, so keeping media in the name is just confusing.
This also keeps compatibility with the `secure-media-uploads` path, and changes new
secure URLs to be `secure-uploads`.
Deprecated settings:
* secure_media -> secure_uploads
* secure_media_allow_embed_images_in_emails -> secure_uploads_allow_embed_images_in_emails
* secure_media_max_email_embed_image_size_kb -> secure_uploads_max_email_embed_image_size_kb
* FEATURE: add composer warning when user haven't been seen in a long time
When a user creates a PM and adds a recipient that hasn't been seen in a
long time then we'll now show a warning in composer indicating that the
user hasn't been seen in a long time.
This will replace `enable_personal_messages` and
`min_trust_to_send_messages`, this commit introduces
the setting `personal_message_enabled_groups`
and uses it in all places that `enable_personal_messages`
and `min_trust_to_send_messages` currently apply.
A migration is included to set `personal_message_enabled_groups`
based on the following rules:
* If `enable_personal_messages` was false, then set
`personal_message_enabled_groups` to `3`, which is
the staff auto group
* If `min_trust_to_send_messages` is not default (1)
and the above condition is false, then set the
`personal_message_enabled_groups` setting to
the appropriate auto group based on the trust level
* Otherwise just set `personal_message_enabled_groups` to
11 which is the TL1 auto group
After follow-up PRs to plugins using these old settings, we will be
able to drop the old settings from core, in the meantime I've added
DEPRECATED notices to their descriptions and added them
to the deprecated site settings list.
This commit also introduces a `_map` shortcut method definition
for all `group_list` site settings, e.g. `SiteSetting.personal_message_enabled_groups`
also has `SiteSetting.personal_message_enabled_groups_map` available,
which automatically splits the setting by `|` and converts it into
an array of integers.
Right now the experimental user menu sorts notifications the same way that the old menu does: unread high-priority notifications are shown first in reverse-chronological order followed by everything else also in reverse-chronological order. However, since the experimental user menu has dedicated tabs for some notification types and each tab displays a badge with the count of unread notifications in the tab, we feel like it makes sense to change how notifications are sorted in the experimental user menu to this:
1. unread high-priority notifications
2. unread regular notifications
3. all read notifications (both high-priority and regular)
4. within each group, notifications are sorted in reverse-chronological order (i.e. newest is shown first).
This new sorting logic applies to all tabs in the experimental user menu, however it doesn't change anything in the old menu. With this change, if a tab in the experimental user menu shows an unread notification badge for a really old notification, it will be surfaced to the top and prevents confusing scenarios where a user sees an unread notification badge on a tab, but the tab doesn't show the unread notification because it's too old to make it to the list.

The generate RSA key and import theme routes worked separate from each
other. The RSA key returned both the public and private key and it was
the frontend which posted the private key back to the server. With this
commit, only the public key is necessary as the server keeps a map of
public and private keys that is used to get the private key back from
a public key.
`TopicQueryParams` allows for `match_all_tags` to be passed as a query parameter. `TagsController` forces the value to be true.
This change allows a value to be passed, and only sets it to true if no value has been set. It then uses `ActiveModel::Type::Boolean.new.cast` to compare the value.
Previously, this would require manually adding `?safe_mode=...` multiple times during the email-based login flow. `/u/admin-login` is often used when debugging a site, so it makes sense for this to be easier.
This commit introduces a new checkbox on the `/u/admin-login` screen. When checked, it'll set the safe_mode parameter on the `/email-login` link, and then pass it all the way through to the homepage redirect.
- `no_custom` -> `no_themes` (history: before themes existed, we had a similar tool called 'customizations')
- `only_official` -> `no_unofficial_plugins` (matches format of `no_themes` and `no_plugins`, and makes it clear that this doesn't affect themes)
- `?safe_mode=no_themes%2C%no_plugins` -> `?safe_mode=no_themes,no_plugins` (the query portion of a URL does not require commas to be encoded. This is much nicer to read)
- If `no_plugins` is chosen from `/safe-mode` the URL generated will omit the superfluous `no_unofficial_plugins` flag
- Some tweaks to copy on `/safe-mode`
A public key must be added to GitHub when installing private themes.
When the process happens asynchronously (for example if the admin does
not have admin permissions to the GitHub repository), installing
private themes becomes very difficult.
In this case, the Discourse admin can partially install the theme by
letting Discourse save the private key, create a placeholder theme and
give the admin a public key to be used as a deploy key. After the key
is installed, the admin can finish theme installation by pressing a
button on the theme page.
Hard deleting topics that contained soft deleted posts or small actions
used to create orphan posts because only the first post was hard

in the topic that must be hard deleted first or hard deletes all small

action because there is no wrench menu).

Similar to the bookmarks tab in the new user menu, the messages tab also displays a mix of notifications and messages.

The bookmarks tab in the new user menu is different from the other tabs in that it can display a mixture of notifications and bookmarks. When there are unread bookmark reminder notifications, the tab displays all of these notifications at the top and fills the remaining space in the menu with the rest of the bookmarks. The bubble/badge count on the bookmarks tab indicates how many unread bookmark reminder notifications there are.
On the technical aspect, since this commit introduces a new `bookmark-item` component, we've done some refactoring so that all 3 "item" components (`notification-item`, `reviewable-item` and the new `bookmark-item`) inherit from a base component and get identical HTML structure so they all look consistent.

* FEATURE: Add case-sensitivity flag to watched_words
Currently, all watched words are matched case-insensitively. This flag
allows a watched word to be flagged for case-sensitive matching.
To allow allow for backwards compatibility the flag is set to false by
default.
* FEATURE: Support case-sensitive creation of Watched Words via API
Extend admin creation and upload of Watched Words to support case
sensitive flag. This lays the ground work for supporting
case-insensitive matching of Watched Words.
Support for an extra column has also been introduced for the Watched
Words upload CSV file. The new column structure is as follows:
word,replacement,case_sentive
* FEATURE: Enable case-sensitive matching of Watched Words
WordWatcher's word_matcher_regexp now returns a list of regular
expressions instead of one case-insensitive regular expression.
With the ability to flag a Watched Word as case-sensitive, an action
can have words of both sensitivities.This makes the use of the global
Regexp::IGNORECASE flag added to all words problematic.
To get around platform limitations around the use of subexpression level
switches/flags, a list of regular expressions is returned instead, one for each
case sensitivity.
Word matching has also been updated to use this list of regular expressions
instead of one.
* FEATURE: Use case-sensitive regular expressions for Watched Words
Update Watched Words regular expressions matching and processing to handle
the extra metadata which comes along with the introduction of
case-sensitive Watched Words.
This allows case-sensitive Watched Words to matched as such.
* DEV: Simplify type casting of case-sensitive flag from uploads
Use builtin semantics instead of a custom method for converting
string case flags in uploaded Watched Words to boolean.
* UX: Add case-sensitivity details to Admin Watched Words UI
Update Watched Word form to include a toggle for case-sensitivity.
This also adds support for, case-sensitive testing and matching of Watched Word
in the admin UI.
* DEV: Code improvements from review feedback
- Extract watched word regex creation out to a utility function
- Make JS array presence check more explicit and readable
* DEV: Extract Watched Word regex creation to utility function
Clean-up work from review feedback. Reduce code duplication.
* DEV: Rename word_matcher_regexp to word_matcher_regexp_list
Since a list is returned now instead of a single regular expression,
change `word_matcher_regexp` to `word_matcher_regexp_list` to better communicate
this change.
* DEV: Incorporate WordWatcher updates from upstream
Resolve conflicts and ensure apply_to_text does not remove non-word characters in matches
that aren't at the beginning of the line.
Some errors (e.g. InvalidAccess) are rendered with `include_ember: true`. Booting the ember app requires that the 'preload' data is rendered in the HTML.
If a particular route was configured to `skip_before_action :preload_json`, and then went on to raise an InvalidAccess error, then we'd attempt to render the Ember app without the preload json. This led to a blank screen and a client-side error.
This commit ensures that error pages will fallback to the no_ember view if there is no preload data. It also adds a sanity check in `discourse-bootstrap` so that it's easier for us to identify similar errors in future.
This commit removes the ability to enable/disable the Sidebar on a per
user basis and introduces a site wide setting. For testing purposes, sidebar can be enabled/disabled via the `enable_sidebar=1` or `enable_sidebar=0` query param.
The idea behind this refactor is to centralise all of the user ignoring / muting / disallow PM checks in a single place, so they can be used consistently in core as well as for plugins like chat, while improving the main bulk of the checks to run in a single fast non-AR query.
Also fixed up the invite error when someone is muting/ignoring the user that is trying to invite them to the topic.
* FIX: Posts can belong to hard-deleted topics
This was a problem when serializing deleted posts because they might
belong to a topic that was permanently deleted. This caused to DB
lookup to fail immediately and raise an exception. In this case, the
endpoint returned a 404.
* FIX: Remove N+1 queries
Deleted topics were not loaded because of the default scope that
filters out all deleted topics. It executed a query for each deleted
topic.
Before, whispers were only available for staff members.
Config has been changed to allow to configure privileged groups with access to whispers. Post migration was added to move from the old setting into the new one.
I considered having a boolean column `whisperer` on user model similar to `admin/moderator` for performance reason. Finally, I decided to keep looking for groups as queries are only done for current user and didn't notice any N+1 queries.
When calling the API to delete a user:
```
curl -X DELETE "https://discourse.example.com/admin/users/159.json" \
-H "Content-Type: multipart/form-data;" \
-H "Api-Key: ***" \
-H "Api-Username: ***" \
-F "delete_posts=true" \
-F "block_email=false" \
-F "block_urls=false" \
-F "block_ip=false"
```
Setting the parameters `block_email`, `block_urls` and `block_ip`explicitly to `false` did not work because the values weren't being parsed to boolean.
In certain situations, a logged in user can redeem an invite with an email that
either doesn't match the invite's email or does not adhere to the email domain
restriction of an invite link. The impact of this flaw is aggrevated
when the invite has been configured to add the user that accepts the
invite into restricted groups.

when CSP report collection is enabled.
This ensures that invalid reports will not cause log floods and simply
returns a 422 error.

At some point in the past we decided to rename the 'regular' notification state of topics/categories to 'normal'. However, some UI copy was missed when the initial renaming was done so this commit changes the spots that were missed to the new name.
Presence endpoints are often called asynchronously at the same time as other request, and never need to modify the session. Skipping ensures that an unneeded cookie rotation doesn't race against another request and cause issues.
This change brings presence in line with message-bus's behaviour.
As part of this commit, a bug where updating a tag's notification level on the server side does not update the state of the user's tag notification levels on the client side is fixed too.
The `WebhookController` inherits directly from `ActionController::Base`. Since Rails 5.2, forgery protection has been enabled by default. When we applied those new defaults in 0403a8633b, it took effect on this controller and broke integrations.
This commit explicitly disables CSRF protection on these webhook routes, and updates the specs so they'll catch this kind of regression in future.
This security fix affects sites which have `SiteSetting.must_approve_users`
enabled. There are intentional and unintentional cases where invited
users can be auto approved and are deemed to have skipped the staff approval process.
Instead of trying to reason about when auto-approval should happen, we have decided that
enabling the `must_approve_users` setting going forward will just mean that all new users
must be explicitly approved by a staff user in the review queue. The only case where users are auto
approved is when the `auto_approve_email_domains` site setting is used.

Previous to this fix, in production we were getting 500 errors from
bootstrap.json cause script_asset_path can not find plugin-tests
Opted for the simplest fix that is omitting the files in production
Previously we limited Discourse Connect provider to 1 secret per domain.
This made it pretty awkward to cycle secrets in environments where config
takes time to propagate
This change allows for the same domain to have multiple secrets
Also fixes internal implementation on DiscourseConnectProvider which was
not thread safe as it leaned on class variables to ferry data around

Previously we hardcoded the DOWNLOAD_URL_EXPIRES_AFTER_SECONDS const
inside S3Helper to be 5 minutes (300 seconds). For various reasons,
some hosted sites may need this to be longer for other integrations.
The maximum expiry time for presigned URLs is 1 week (which is
604800 seconds), so that has been added as a validation on the
setting as well. The setting is hidden because 99% of the time
it should not be changed.
When searching for PMs or PMs in a group inbox, results in the header search were not being limited to 5 with a "More" link to the full page search. This PR fixes that.
It also simplifies the logic and updates the search API docs to include recently added `in:messages` and `group_messages:groupname` options.
When saving / creating bookmarks, we have code to save
the user's preference of bookmark_auto_delete_preference
to their user_options.
Unfortunately this can cause weirdness when plugins
have code using BookmarkManager to set the auto delete preference for
only a specific bookmark.
This commit introduces a save_user_preferences option (false
by default) so that this user preference is not saved unless
specified by the consumer of BookmarkManager, so plugins will
not have to worry about it.
This commit migrates all bookmarks to be polymorphic (using the
bookmarkable_id and bookmarkable_type) columns. It also deletes
all the old code guarded behind the use_polymorphic_bookmarks setting
and changes that setting to true for all sites and by default for
the sake of plugins.
No data is deleted in the migrations, the old post_id and for_topic
columns for bookmarks will be dropped later on.
The title had to be added both on the 404 page generated by the server
side, displayed when the user reaches a bad page directly and the 404
page rendered by Ember when a user reaches a missing topic while
navigating the forum.
The logic in 06893380 only works for `.js` files. It breaks down for `.br.js` and `.gz.js` files. This commit makes things more robust by extracting only the base_url from the service-worker JS, and taking the map filename from the original `sourceMappingURL` comment.
`script_asset_path('.../blah.js.map')` was appending `.js`, which would result in a filename like `.js.map.js`. It would also lose the `/assets` prefix, since the map files are not included in the sprockets manifest.
This commit updates the sourceMappingURL rewriting logic to calculate the service-worker's own JS url, and then append `.map`.
We have a .ics endpoint for user bookmarks, this
commit makes it so polymorphic bookmarks work on
that endpoint, using the serializer associated with
the RegisteredBookmarkable.
A bit of a mixed bag, this addresses several edge areas of bookmarks and makes them compatible with polymorphic bookmarks (hidden behind the `use_polymorphic_bookmarks` site setting). The main ones are:
* ExportUserArchive compatibility
* SyncTopicUserBookmarked job compatibility
* Sending different notifications for the bookmark reminders based on the bookmarkable type
* Import scripts compatibility
* BookmarkReminderNotificationHandler compatibility
This PR also refactors the `register_bookmarkable` API so it accepts a class descended from a `BaseBookmarkable` class instead. This was done because we kept having to add more and more lambdas/properties inline and it was very messy, so a factory pattern is cleaner. The classes can be tested independently as well.
Some later PRs will address some other areas like the discourse narrative bot, advanced search, reports, and the .ics endpoint for bookmarks.
This was due to a server side bug when unicode usernames have been
enabled. We were double encoding the unicode username in the URL
resulting in a invalid URL.
Previously, accessing the Rails app directly in development mode would give you assets from our 'legacy' Ember asset pipeline. The only way to run with Ember CLI assets was to run ember-cli as a proxy. This was quite limiting when working on things which are bypassed when using the ember-cli proxy (e.g. changes to `application.html.erb`). Also, since `ember-auto-import` introduced chunking, visiting `/theme-qunit` under Ember CLI was failing to include all necessary chunks.
This commit teaches Sprockets about our Ember CLI assets so that they can be used in development mode, and are automatically collected up under `/public/assets` during `assets:precompile`. As a bonus, this allows us to remove all the custom manifest modification from `assets:precompile`.
The key changes are:
- Introduce a shared `EmberCli.enabled?` helper
- When ember-cli is enabled, add ember-cli `/dist/assets` as the top-priority Rails asset directory
- Have ember-cli output a `chunks.json` manifest, and teach `preload_script` to read it and append the correct chunks to their associated `afterFile`
- Remove most custom ember-cli logic from the `assets:precompile` step. Instead, rely on Rails to take care of pulling the 'precompiled' assets into the `public/assets` directory. Move the 'renaming' logic to runtime, so it can be used in development mode as well.
- Remove fingerprinting from `ember-cli-build`, and allow Rails to take care of things
Long-term, we may want to replace Sprockets with the lighter-weight Propshaft. The changes made in this commit have been made with that long-term goal in mind.
tldr: when you visit the rails app directly, you'll now be served the current ember-cli assets. To keep these up-to-date make sure either `ember serve`, or `ember build --watch` is running. If you really want to load the old non-ember-cli assets, then you should start the server with `EMBER_CLI_PROD_ASSETS=0`. (the legacy asset pipeline will be removed very soon)
It used to show the warning that said only members of certain groups
could view the topic even if the group "everyone" was listed in
category's permission list.
Discourse has the Discourse Connect Provider protocol that makes it possible to
use a Discourse instance as an identity provider for external sites. As a
natural extension to this protocol, this PR adds a new feature that makes it
possible to use Discourse as a 2FA provider as well as an identity provider.
The rationale for this change is that it's very difficult to implement 2FA
support in a website and if you have multiple websites that need to have 2FA,
it's unrealistic to build and maintain a separate 2FA implementation for each
one. But with this change, you can piggyback on Discourse to take care of all
the 2FA details for you for as many sites as you wish.
To use Discourse as a 2FA provider, you'll need to follow this guide:
https://meta.discourse.org/t/-/32974. It walks you through what you need to
implement on your end/site and how to configure your Discourse instance. Once
you're done, there is only one additional thing you need to do which is to
include `require_2fa=true` in the payload that you send to Discourse.
When Discourse sees `require_2fa=true`, it'll prompt the user to confirm their
2FA using whatever methods they've enabled (TOTP or security keys), and once
they confirm they'll be redirected back to the return URL you've configured and
the payload will contain `confirmed_2fa=true`. If the user has no 2FA methods
enabled however, the payload will not contain `confirmed_2fa`, but it will
contain `no_2fa_methods=true`.
You'll need to be careful to re-run all the security checks and ensure the user
can still access the resource on your site after they return from Discourse.
This is very important because there's nothing that guarantees the user that
will come back from Discourse after they confirm 2FA is the same user that
you've redirected to Discourse.
Internal ticket: t62183.
* FEATURE: Let sites add a sitemap.xml file.
This PR adds the same features discourse-sitemap provides to core. Sitemaps are only added to the robots.txt file if the `enable_sitemap` setting is enabled and `login_required` disabled.
After merging discourse/discourse-sitemap#34, this change will take priority over the sitemap plugin because it will disable itself. We're also using the same sitemaps table, so our migration won't try to create it
again using `if_not_exists: true`.
After this commit, category group permissions can only be seen by users
that are allowed to manage a category. In the past, we inadvertently
included a category's group permissions settings in `CategoriesController#show`
and `CategoriesController#find_by_slug` endpoints for normal users when
those settings are only a concern to users that can manage a category.
Previously we only supported a single 'required tag group' for a category. This commit allows admins to specify multiple required tag groups, each with their own minimum tag count.
A new category_required_tag_groups database table replaces the existing columns on the categories table. Data is automatically migrated.
This did not work properly everytime because the destination URL was
saved in a cookie and that can be lost for various reasons. This commit
redirects the user to invited topic if it exists.
This commit introduces a new use_polymorphic_bookmarks site setting
that is default false and hidden, that will be used to help continuous
development of polymorphic bookmarks. This setting **should not** be
enabled anywhere in production yet, it is purely for local development.
This commit uses the setting to enable create/update/delete actions
for polymorphic bookmarks on the server and client side. The bookmark
interactions on topics/posts are all usable. Listing, searching,
sending bookmark reminders, and other edge cases will be handled
in subsequent PRs.
Comprehensive UI tests will be added in the final PR -- we already
have them for regular bookmarks, so it will just be a matter of
changing them to be for polymorphic bookmarks.
* FIX: Redirect if Discourse-Xhr-Redirect is present
`handleRedirect` was passed an wrong argument type (a string) instead of
a jqXHR object and missed the fields checked in condition, thus always
evaluating to `false`.
* FIX: Add `errors` field if group update confirmation
An explicit confirmation about the effect of the group update is
required if the default notification level changes. Previously, if the
confirmation was missing the API endpoint failed silently returning
a 200 response code and a `user_count` field. This change ensures that
a proper error code is returned (422), a descriptive error message and
the additional information in the `user_count` field.
This commit also refactors the API endpoint to use the
`Discourse-Xhr-Redirect` header to redirect the user if the group is
no longer visible.
Previously we would issue a 403 for all invalid routes under `/tags/c/...`, which is not semantically correct. In some cases, these 403'd routes would then be handled successfully in the Ember app, leading to some very confusing behavior.
* DEV: Allow params to be passed on topic redirects
There are several places where we redirect a url to a standard topic url
like `/t/:slug/:topic_id` but we weren't always passing query parameters
to the new url.
This change allows a few more query params to be included on the
redirect. The new params that are permitted are page, print, and
filter_top_level_replies. Any new params will need to be specified.
This also prevents the odd trailing empty page param that would
sometimes appear on a redirect. `/t/:slug/:id.json?page=`
* rubocop: fix missing space after comma
* fix another page= reference
* FEATURE: use canonical links in posts.rss feed
Previously we used non canonical links in posts.rss
These links get crawled frequently by crawlers when discovering new
content forcing crawlers to hop to non canonical pages just to end up
visiting canonical pages
This uses up expensive crawl time and adds load on Discourse sites
Old links were of the form:
`https://DOMAIN/t/SLUG/43/21`
New links are of the form
`https://DOMAIN/t/SLUG/43?page=2#post_21`
This also adds a post_id identified element to crawler view that was
missing.
Note, to avoid very expensive N+1 queries required to figure out the
page a post is on during rss generation, we cache that information.
There is a smart "cache breaker" which ensures worst case scenario is
a "page drift" - meaning we would publicize a post is on page 11 when
it is actually on page 10 due to post deletions. Cache holds for up to
12 hours.
Change only impacts public post RSS feeds (`/posts.rss`)
* DEV: Deprecate /posts/:id/reply-ids/all
It was added in ed4c0c4a63 and its only use was removed in b58867b6e9
Nothing in all-the* seems to be using this endpoint.
* Update app/controllers/posts_controller.rb

The `blocked onebox domains` setting lets site owners change what sites
are allowed to be oneboxed. When a link is entered into a post,
Discourse checks the domain of the link against that setting and blocks
the onebox if the domain is blocked. But if there's a chain of
redirects, then only the final destination website is checked against
the site setting.
This commit amends that behavior so that every website in the redirect
chain is checked against the site setting, and if anything is blocked
the original link doesn't onebox at all in the post. The
`Discourse-No-Onebox` header is also checked in every response and the
onebox is blocked if the header is set to "1".
Additionally, Discourse will now include the `Discourse-No-Onebox`
header with every response if the site requires login to access content.
This is done to signal to a Discourse instance that it shouldn't attempt
to onebox other Discourse instances if they're login-only. Non-Discourse
websites can also use include that header if they don't wish to have
Discourse onebox their content.
Internal ticket: t59305.
Previously, if an admin user tried to add/remove
users to another user's ignored list, it would
be added to their own ignore list because the
controller used current_user. Now for admins only
a source_user_id parameter can be passed through,
which will be used to ignore the target user for
that source user.
When creating files with create-multipart, if the file
size was somehow zero we were showing a very unhelpful
error message to the user. Now we show a nicer message,
and proactively don't call the API if we know the file
size is 0 bytes in JS, along with extra console logging
to help with debugging.
This PR adds an extra description to the 2FA page when granting a user admin access. It also introduces a general system for adding customized descriptions that can be used by future actions.
(Follow-up to dd6ec65061)
Discourse users and associated accounts are created or updated when a
user logins or connects the account using their account preferences.
This new API can be used to create associated accounts and users too,
if necessary.
Our @mention user search prioritized users based on prefix matches.
So if searching for `sa` we will display `sam`, `asam` in that order
Previously, we did not prioritize group matches based on prefix. This change ensures better parity.
Implementation notes:
1. User search only prioritizes based on username prefix, not name prefix. TBD if we want to change that.
2. @mention on client side will show 0 group matches if we fill up all the spots with user matches. TBD if we want to unconditionally show the first / second group match.

This feature was rarely used, could be used for spamming users and was
impossible to add a context to why the user was notified of a topic. A
simple private messages that includes the link and personalized message
can be used instead.
* DEV: Show only top level replies
Adds a new query param to the topic view so that we can filter out posts
that aren't top level replies. If a post is a reply to another post
instead of the original topic post we should not include it in the
response if the `filter_top_level_replies` query param is present.
* add rspec test
This allows text editors to use correct syntax coloring for the heredoc sections.
Heredoc tag names we use:
languages: SQL, JS, RUBY, LUA, HTML, CSS, SCSS, SH, HBS, XML, YAML/YML, MF, ICS
other: MD, TEXT/TXT, RAW, EMAIL
* FEATURE: upload an avatar option for uploading avatars with selectable avatars
Allow staff or users at or above a trust level to upload avatars even when the site
has selectable avatars enabled.
Everyone can still pick from the list of avatars. The option to upload is shown
below the selectable avatar list.
refactored boolean site setting into an enum with the following values:
disabled: No selectable avatars enabled (default)
everyone: Show selectable avatars, and allow everyone to upload custom avatars
tl1: Show selectable avatars, but require tl1+ and staff to upload custom avatars
tl2: Show selectable avatars, but require tl2+ and staff to upload custom avatars
tl3: Show selectable avatars, but require tl3+ and staff to upload custom avatars
tl4: Show selectable avatars, but require tl4 and staff to upload custom avatars
staff: Show selectable avatars, but only allow staff to upload custom avatars
no_one: Show selectable avatars. No users can upload custom avatars

Currently, providing things like `filter[%24acunetix]=1` to
`UserActionsController#index` will throw an exception because instead of
getting a string as expected, we get a hash instead.
This patch simply uses `#permit` from strong parameters properly: first
we apply it on the whole parameters, this way it filters the keys we’re
interested in. By doing this, if the value is a hash for example, the
whole key/value pair will be ignored completely.
This commit handles the edge case where a draft is lost with no warnings if the user edits the title (or category/tags) of a topic while they're replying.to the same topic. Repro steps are as follows:
1. Start replying to a topic and type enough to get a draft saved.
2. Scroll up to the topic title and click the pencil icon next to the topic title, change the title, category and/or tags, and then save the changes.
3. Reload the page and you'll see that the draft is gone.
This happens because we only allow 1 draft per topic per user and when you edit the title of a topic that you're replying to, from the server perspective it'll look like as if you've submitted your reply so it will advance the draft sequence for the topic and delete the draft.
The fix in this commit makes `PostRevisor` skip advancing the draft sequence when a topic's title is edited using the pencil button next to the title.

We validate the *format* of email addresses in many places with a match against
a regex, often with very slightly different syntax.
Adding a separate EmailAddressValidator simplifies the code in a few spots and
feels cleaner.
Deprecated the old location in case someone is using it in a plugin.
No functionality change is in this commit.
Note: the regex used at the moment does not support using address literals, e.g.:
* localpart@[192.168.0.1]
* localpart@[2001:db8::1]
2FA support in Discourse was added and grown gradually over the years: we first
added support for TOTP for logins, then we implemented backup codes, and last
but not least, security keys. 2FA usage was initially limited to logging in,
but it has been expanded and we now require 2FA for risky actions such as
adding a new admin to the site.
As a result of this gradual growth of the 2FA system, technical debt has
accumulated to the point where it has become difficult to require 2FA for more
actions. We now have 5 different 2FA UI implementations and each one has to
support all 3 2FA methods (TOTP, backup codes, and security keys) which makes
it difficult to maintain a consistent UX for these different implementations.
Moreover, there is a lot of repeated logic in the server-side code behind these
5 UI implementations which hinders maintainability even more.
This commit is the first step towards repaying the technical debt: it builds a
system that centralizes as much as possible of the 2FA server-side logic and
UI. The 2 main components of this system are:
1. A dedicated page for 2FA with support for all 3 methods.
2. A reusable server-side class that centralizes the 2FA logic (the
`SecondFactor::AuthManager` class).
From a top-level view, the 2FA flow in this new system looks like this:
1. User initiates an action that requires 2FA;
2. Server is aware that 2FA is required for this action, so it redirects the
user to the 2FA page if the user has a 2FA method, otherwise the action is
performed.
3. User submits the 2FA form on the page;
4. Server validates the 2FA and if it's successful, the action is performed and
the user is redirected to the previous page.
A more technically-detailed explanation/documentation of the new system is
available as a comment at the top of the `lib/second_factor/auth_manager.rb`
file. Please note that the details are not set in stone and will likely change
in the future, so please don't use the system in your plugins yet.
Since this is a new system that needs to be tested, we've decided to migrate
only the 2FA for adding a new admin to the new system at this time (in this
commit). Our plan is to gradually migrate the remaining 2FA implementations to
the new system.
For screenshots of the 2FA page, see PR #15377 on GitHub.
When parent category or grandparent category is muted, then category should be muted as well.
Still, it can be overridden by setting individual subcategory notification level.
CategoryUser record is not created, mute for subcategories is purely virtual.
This can happen if the topic to which a user is invited is in a private
category and the user was not invited to one of the groups that can see
that specific category.
This used to be a warning and this commit makes it an error.
Whenever we got a bounced email in the Email::Receiver we
previously would just set bounced: true on the EmailLog and
discard the status/diagnostic code. This commit changes this
flow to store the bounce error code (defined in the RFC at
https://www.iana.org/assignments/smtp-enhanced-status-codes/smtp-enhanced-status-codes.xhtml)
not just in the Email::Receiver, but also via webhook events
from other mail services and from SNS.
This commit does not surface the bounce error in the UI,
we can do that later if necessary.
We serve `service-worker.js` in an unusual way, which means that the sourcemap is not available on an adjacent path. This means that the browser fails to fetch the map, and shows an error in the console.
This commit re-writes the source map reference in the static_controller to be an absolute link to the asset (including the appropriate CDN, if enabled), and adds a spec for the behavior.
It's important to do this at runtime, rather than JS precompile time, so that changes to CDN configuration do not require re-compilation to take effect.
This adds logic to increase an `InvitedUser` record, increase
`redemption_count` and create a `:invitee_accepted` to let the inviter
know that the invitee used the invite.
Initial support for this was implemented in commit 9969631.
Sorting group members worked always kept the group owners at the top of
the list. This commit keeps the group owners at the top of the list only
when no order exists.
This commits adds a new advance_draft to PostCreator that controls if
the draft sequence will be advanced or not. If the draft sequence is
advanced then the old drafts will be cleared. This used to happen for
posts created by plugins or through the API and cleared user drafts
by mistake.
* FEATURE: Add external_id to topics
This commit allows for topics to be created and fetched by an
external_id. These changes are API only for now as there aren't any
front changes.
* add annotations
* add external_id to this spec
* Several PR feedback changes
- Add guardian to find topic
- 403 is returned for not found as well now
- add `include_external_id?`
- external_id is now case insensitive
- added test for posts_controller
- added test for topic creator
- created constant for max length
- check that it redirects to the correct path
- restrain external id in routes file
* remove puts
* fix tests
* only check for external_id in webhook if exists
* Update index to exclude external_id if null
* annotate
* Update app/controllers/topics_controller.rb
We need to check whether the topic is present first before passing it to the guardian.

This commit allows group SMTP emails to be sent with a
different from email address that has been set up as an
alias in the email provider. Emails from the alias will
be grouped correctly using Message-IDs in the mail client,
and replies to the alias go into the correct group inbox.
Job arguments go via JSON, and so symbols will appear as strings in the Job's `#execute` method. The latest version of Sidekiq has started warning about this to reduce developer confusion.
- Limit bulk re-invite to 1 time per day
- Move bulk invite by csv behind a site setting (hidden by default)
- Bump invite expiry from 30 -> 90 days
## Updates to rate_limiter
When limiting reinvites I found that **staff** are never limited in any way. So I updated the **rate_limiter** model to allow for a few things:
- add an optional param of `staff_limit`, which (when included and passed values, and the user passes `.staff?`) will override the default `max` & `secs` values and apply them to the user.
- in the case you **do** pass values to `staff_limit` but the user **does not** pass `staff?` the standard `max` & `secs` values will be applied to the user.
This should give us enough flexibility to
1. continue to apply a strict rate limit to a standard user
2. but also apply a secondary (less strict) limit to staff
When the record is not saved, we should display a proper message.
One potential reason can be plugins for example discourse-calendar is specifying that only first post can contain event
* FIX: Remove svg icons from webmanifest shortcuts
While SVGs are valid in the webmanifest, Chromium has not implemented
support for it in this specific manifest member.
Revert when https://bugs.chromium.org/p/chromium/issues/detail?id=1091612
lands.
* fix test
When staff visits the user profile of another user, the `email` field
in the model is empty. In this case, staff cannot send the reset email
password because nothing is passed in the `login` field.
This commit changes the behavior for staff users to allow resetting
password by username instead.
The UI used to request a password reset by username when the user was
logged in. This did not work when hide_email_already_taken site setting
was enabled, which disables the lookup-by-username functionality.
This commit also introduces a check to ensure that the parameter is an
email when hide_email_already_taken is enabled as the single allowed
type is email (no usernames are allowed).
* FIX: Mark invites flash messages as HTML safe.
This change should be safe as all user inputs included in the errors are sanitized before sending it back to the client.
Context: https://meta.discourse.org/t/html-tags-are-explicit-after-latest-update/214220
* If somebody adds a new error message that includes user input and doesn't sanitize it, using html-safe suddenly becomes unsafe again. As an extra layer of protection, we make the client sanitize the error message received from the backend.
* Escape user input instead of sanitizing
* FEATURE: Export topics to markdown
The route `/raw/TOPIC_ID` will now export whole topics (paginated to 100
posts) in a markdown format.

This reverts commit 2c7906999a.
The changes break some things in local development (putting JS files
into minified files, not allowing debugger, and others)
This reverts commit ea84a82f77.
This is causing problems with `/theme-qunit` on legacy, non-ember-cli production sites. Reverting while we work on a fix
This is quite complex as it means that in production we have to build
Ember CLI test files and allow them to be used by our Rails application.
There is a fair bit of glue we can remove in the future once we move to
Ember CLI completely.
An admin could search for all screened ip addresses in a block by
using wildcards. 192.168.* returned all IPs in range 192.168.0.0/16.
This feature allows admins to search for a single IP address in all
screened IP blocks. 192.168.0.1 returns all IP blocks that match it,
for example 192.168.0.0/16.
* FEATURE: Remove roll up button for screened IPs
* FIX: Match more specific screened IP address first
The new warnings cover more cases and more accurate. Most of the
warnings will be visible only to staff members because otherwise they
would leak information about user's preferences.
Also:
* Remove an unused method (#fill_email)

This commit adds a check that runs regularly as per
2d68e5d942 which tests the
credentials of groups with SMTP or IMAP enabled. If any issues
are found with those credentials a high priority problem is added to the
admin dashboard.
This commit also formats the admin dashboard differently if
there are high priority problems, bringing them to the top of
the list and highlighting them.
The problem will be cleared if the issue is fixed before the next
problem check, or if the group's settings are updated with a valid
credential.
* FEATURE: hide_email_address_taken forces use of email in forgot password form
This strengthens this site setting which is meant to be used to harden sites
that are experiencing abuse on forgot password routes.
Previously we would only deny letting people know if forgot password worked on not
New change also bans usage of username for forgot password when enabled
Discourse sent only translation overrides for the current language to the client instead of sending overrides from fallback locales as well. This especially impacted en_GB -> en since most overrides would be done in English instead of English (UK).
This also adds lots of tests for previously untested code.
There's a small caveat: The client currently doesn't handle fallback locales for MessageFormat strings. That is why overrides for those strings always have a higher priority than regular translations. So, as an example, the lookup order for MessageFormat strings in German is:
1. override for de
2. override for en
3. value from de
4. value from en
A plugin API that allows customizing existing topic-backed static pages, like:
faq, tos, privacy (see: StaticController) The block passed to this
method has to return a SiteSetting name that contains a topic id.
```
add_topic_static_page("faq") do |controller|
current_user&.locale == "pl" ? "polish_faq_topic_id" : "faq_topic_id"
end
```
You can also add new pages in a plugin, but remember to add a route,
for example:
```
get "contact" => "static#show", id: "contact"
```
This commit introduces a new site setting "google_oauth2_hd_groups". If enabled, group information will be fetched from Google during authentication, and stored in the Discourse database. These 'associated groups' can be connected to a Discourse group via the "Membership" tab of the group preferences UI.
The majority of the implementation is generic, so we will be able to add support to more authentication methods in the near future.

We don't need it anymore. Actually, I removed using of it on the client side a long time ago, when I was working on improving blank page syndrome on user activity pages (see https://github.com/discourse/discourse/pull/14311).
This PR also removes some old resource strings that we don't use anymore. We have new strings for blank pages.
Currently the Message-IDs we send out for outbound email
are not unique; for a post they look like:
topic/TOPIC_ID/POST_ID@HOST
And for a topic they look like:
topic/TOPIC_ID@HOST
This commit changes the outbound Message-IDs to also have
a random suffix before the host, so the new format is
like this:
topic/TOPIC_ID/POST_ID.RANDOM_SUFFIX@HOST
Or:
topic/TOPIC_ID.RANDOM_SUFFIX@HOST
This should help with email deliverability. This change
is backwards-compatible, the old Message-ID format will
still be recognized in the mail receiver flow, so people
will still be able to reply using Message-IDs, In-Reply-To,
and References headers that have already been sent.
This commit also refactors Message-ID related logic
to a central location, and adds judicious amounts of
tests and documentation.
When redirecting to login, we store a destination_url cookie, which the user is then redirected to after login. We never want the user to be redirected to a JSON URL. Instead, we should return a 403 in these situations.
This should also be much less confusing for API consumers - a 403 is a better representation than a 302.

`auto_update` is true by default at the database level, but it doesn't make sense for `auto_update` to be true on themes that are not imported from a Git repository.
Under some conditions, these varied responses could lead to cache poisoning, hence the 'security' label.
Previously the Rails application would serve JSON data in place of HTML whenever Ember CLI requested an `application.html.erb`-rendered page. This commit removes that logic, and instead parses the HTML out of the standard response. This means that Rails doesn't need to customize its response for Ember CLI.
* REFACTOR: Improve support for consolidating notifications.
Before this commit, we didn't have a single way of consolidating notifications. For notifications like group summaries, we manually removed old ones before creating a new one. On the other hand, we used an after_create callback for likes and group membership requests, which caused unnecessary work, as we need to delete the record we created to replace it with a consolidated one.
We now have all the consolidation rules centralized in a single place: the consolidation planner class. Other parts of the app looking to create a consolidable notification can do so by calling Notification#consolidate_or_save!, instead of the default Notification#create! method.
Finally, we added two more rules: one for re-using existing group summaries and another for deleting duplicated dashboard problems PMs notifications when the user is tracking the moderator's inbox. Setting the threshold to one forces the planner to apply this rule every time.
I plan to add plugin support for adding custom rules in another PR to keep this one relatively small.
* DEV: Introduces a plugin API for consolidating notifications.
This commit removes the `Notification#filter_by_consolidation_data` scope since plugins could have to define their criteria. The Plan class now receives two blocks, one to query for an already consolidated notification, which we'll try to update, and another to query for existing ones to consolidate.
It also receives a consolidation window, which accepts an ActiveSupport::Duration object, and filter notifications created since that value.
Recently, the wrong new behavior appeared – we started to suggest to invited users usernames like "user1".
To reproduce:
1. Create an invitation with default settings, do not restrict it to email
2. Copy an invitation link and follow it in incognito mode
See username already filled, with eg “user1”. See screenshot. Should be empty.
This bug was very likely introduced by my recent changes to UserNameSuggester.
We have a couple of site setting, `slow_down_crawler_user_agents` and `slow_down_crawler_rate`, that are meant to allow site owners to signal to specific crawlers that they're crawling the site too aggressively and that they should slow down.
When a crawler is added to the `slow_down_crawler_user_agents` setting, Discourse currently adds a `Crawl-delay` directive for that crawler in `/robots.txt`. Unfortunately, many crawlers don't support the `Crawl-delay` directive in `/robots.txt` which leaves the site owners no options if a crawler is crawling the site too aggressively.
This PR replaces the `Crawl-delay` directive with proper rate limiting for crawlers added to the `slow_down_crawler_user_agents` list. On every request made by a non-logged in user, Discourse will check the User Agent string and if it contains one of the values of the `slow_down_crawler_user_agents` list, Discourse will only allow 1 request every N seconds for that User Agent (N is the value of the `slow_down_crawler_rate` setting) and the rest of requests made within the same interval will get a 429 response.
The `slow_down_crawler_user_agents` setting becomes quite dangerous with this PR since it could rate limit lots if not all of anonymous traffic if the setting is not used appropriately. So to protect against this scenario, we've added a couple of new validations to the setting when it's changed:
1) each value added to setting must 3 characters or longer
2) each value cannot be a substring of tokens found in popular browser User Agent. The current list of prohibited values is: apple, windows, linux, ubuntu, gecko, firefox, chrome, safari, applewebkit, webkit, mozilla, macintosh, khtml, intel, osx, os x, iphone, ipad and mac.
Currently when a user creates posts that are moderated (for whatever
reason), a popup is displayed saying the post needs approval and the
total number of the user’s pending posts. But then this piece of
information is kind of lost and there is nowhere for the user to know
what are their pending posts or how many there are.
This patch solves this issue by adding a new “Pending” section to the
user’s activity page when there are some pending posts to display. When
there are none, then the “Pending” section isn’t displayed at all.

This commit adds token_hash and scopes columns to email_tokens table.
token_hash is a replacement for the token column to avoid storing email
tokens in plaintext as it can pose a security risk. The new scope column
ensures that email tokens cannot be used to perform a different action
than the one intended.
To sum up, this commit:
* Adds token_hash and scope to email_tokens
* Reuses code that schedules critical_user_email
* Refactors EmailToken.confirm and EmailToken.atomic_confirm methods
* Periodically cleans old, unconfirmed or expired email tokens
Use @here to mention all users that were allowed to topic directly or
through group, who liked topics or read the topic. Only first 10 users

This takes the uppy chunking algorithm and combines it with some
form submission from resumable.js for parity with the current
backup controller to make local backup uploads work with uppy.
We can then use this to replace the resumable-upload component
and the resumable.js library from our codebase, once stable.
This is disabled by default, so people using local backups will not
be affected. The enable_experimental_backup_uploader site setting
must be enabled for this to work.
This commit refactors the direct external upload routes (get presigned
put, complete external, create/abort/complete multipart) into a
helper which is then included in both BackupController and the
UploadController. This is done so UploadController doesn't need
strange backup logic added to it, and so each controller implementing
this helper can do their own validation/error handling nicely.
This is a follow up to e4350bb966
Currently, Discourse rate limits all incoming requests by the IP address they
originate from regardless of the user making the request. This can be
frustrating if there are multiple users using Discourse simultaneously while
sharing the same IP address (e.g. employees in an office).
This commit implements a new feature to make Discourse apply rate limits by
user id rather than IP address for users at or higher than the configured trust
level (1 is the default).
For example, let's say a Discourse instance is configured to allow 200 requests
per minute per IP address, and we have 10 users at trust level 4 using
Discourse simultaneously from the same IP address. Before this feature, the 10
users could only make a total of 200 requests per minute before they got rate
limited. But with the new feature, each user is allowed to make 200 requests
per minute because the rate limits are applied on user id rather than the IP
address.
The minimum trust level for applying user-id-based rate limits can be
configured by the `skip_per_ip_rate_limit_trust_level` global setting. The
default is 1, but it can be changed by either adding the
`DISCOURSE_SKIP_PER_IP_RATE_LIMIT_TRUST_LEVEL` environment variable with the
desired value to your `app.yml`, or changing the setting's value in the
`discourse.conf` file.
Requests made with API keys are still rate limited by IP address and the
relevant global settings that control API keys rate limits.
Before this commit, Discourse's auth cookie (`_t`) was simply a 32 characters
string that Discourse used to lookup the current user from the database and the
cookie contained no additional information about the user. However, we had to
change the cookie content in this commit so we could identify the user from the
cookie without making a database query before the rate limits logic and avoid
introducing a bottleneck on busy sites.
Besides the 32 characters auth token, the cookie now includes the user id,
trust level and the cookie's generation date, and we encrypt/sign the cookie to
prevent tampering.

Uppy adds the file name as the "name" parameter in the
payload by default, which means that for things like the
emoji uploader which have a name param used by the controller,
that param will be passed as the file name. We already use
the existing file name if the name param is null, so this
commit just does further cleanup of the name param, removing
the extension if it is a filename so we don't end up with
emoji names like blah_png.
Uppy and Resumable slice up their chunks differently, which causes a difference
in this algorithm. Let's take a 131.6MB file (137951695 bytes) with a 5MB (5242880 bytes)
chunk size. For resumable, there are 26 chunks, and uppy there are 27. This is
controlled by forceChunkSize in resumable which is false by default. The final
chunk size is 6879695 (chunk size + remainder) whereas in uppy it is 1636815 (just remainder).
This means that the current condition of uploaded_file_size + current_chunk_size >= total_size
is hit twice by uppy, because it uses a more correct number of chunks. This
can be solved for both uppy and resumable by checking the _previous_ chunk
number * chunk_size as the uploaded_file_size.
An example of what is happening before that change, using the current
chunk number to calculate uploaded_file_size.
chunk 26: resumable: uploaded_file_size (26 * 5242880) + current_chunk_size (6879695) = 143194575 >= total_size (137951695) ? YES
chunk 26: uppy: uploaded_file_size (26 * 5242880) + current_chunk_size (5242880) = 141557760 >= total_size (137951695) ? YES
chunk 27: uppy: uploaded_file_size (27 * 5242880) + current_chunk_size (1636815) = 143194575 >= total_size (137951695) ? YES
An example of what this looks like after the change, using the previous
chunk number to calculate uploaded_file_size:
chunk 26: resumable: uploaded_file_size (25 * 5242880) + current_chunk_size (6879695) = 137951695 >= total_size (137951695) ? YES
chunk 26: uppy: uploaded_file_size (25 * 5242880) + current_chunk_size (5242880) = 136314880 >= total_size (137951695) ? NO
chunk 27: uppy: uploaded_file_size (26 * 5242880) + current_chunk_size (1636815) = 137951695 >= total_size (137951695) ? YES
This PR introduces a new `enable_experimental_backup_uploads` site setting (default false and hidden), which when enabled alongside `enable_direct_s3_uploads` will allow for direct S3 multipart uploads of backup .tar.gz files.
To make multipart external uploads work with both the S3BackupStore and the S3Store, I've had to move several methods out of S3Store and into S3Helper, including:
* presigned_url
* create_multipart
* abort_multipart
* complete_multipart
* presign_multipart_part
* list_multipart_parts
Then, S3Store and S3BackupStore either delegate directly to S3Helper or have their own special methods to call S3Helper for these methods. FileStore.temporary_upload_path has also removed its dependence on upload_path, and can now be used interchangeably between the stores. A similar change was made in the frontend as well, moving the multipart related JS code out of ComposerUppyUpload and into a mixin of its own, so it can also be used by UppyUploadMixin.
Some changes to ExternalUploadManager had to be made here as well. The backup direct uploads do not need an Upload record made for them in the database, so they can be moved to their final S3 resting place when completing the multipart upload.
This changeset is not perfect; it introduces some special cases in UploadController to handle backups that was previously in BackupController, because UploadController is where the multipart routes are located. A subsequent pull request will pull these routes into a module or some other sharing pattern, along with hooks, so the backup controller and the upload controller (and any future controllers that may need them) can include these routes in a nicer way.
We are only using list_multipart_parts right now in the
uploads controller for multipart uploads to check if the
upload exists; thus we don't need up to 1000 parts.
Also adding a note for future explorers that list_multipart_parts
only gets 1000 parts max, and adding params for max parts
and starting parts.
This commit introduces a new s3:ensure_cors_rules rake task
that is run as a prerequisite to s3:upload_assets. This rake
task calls out to the S3CorsRulesets class to ensure that
the 3 relevant sets of CORS rules are applied, depending on
site settings:
* assets
* direct S3 backups
* direct S3 uploads
This works for both Global S3 settings and Database S3 settings
(the latter set directly via SiteSetting).
As it is, only one rule can be applied, which is generally
the assets rule as it is called first. This commit changes
the ensure_cors! method to be able to apply new rules as
well as the existing ones.
This commit also slightly changes the existing rules to cover
direct S3 uploads via uppy, especially multipart, which requires
some more headers.
This commit changes the emoji uploader to use the UppyUploadMixin,
and makes some minor changes to the emoji uploader (tightening the
copy for drag and drop and adding a percentage for the upload).
Since no other uppy upload mixin components have needed to upload
multiple files so far, this necessitated adding a tracker for the
in progress uploads so we know when to reset the uploader once all
uploads are complete.
At the moment, the emoji uploader cannot be used for direct S3 uploads
because the admin emoji controller creates other records and does other
magic with the emojis. At some point we need to factor this kind of thing
into the ExternalUploadManager.transform! action to complete external
uploads.
* FIX: allowed_theme_ids should not be persisted in GlobalSettings
It was observed that the memoized value of `GlobalSetting.allowed_theme_ids` would be persisted across requests, which could lead to unpredictable/undesired behaviours in a multisite environment.
This change moves that logic out of GlobalSettings so that the returned theme IDs are correct for the current site.
Uses get_set_cache, which ultimately uses DistributedCache, which will take care of multisite issues for us.
By default, Rails only includes the Vary:Accept header in responses when the Accept: header is included in the request. This means that proxies/browsers may cache a response to a request with a missing Accept header, and then later serve that cached version for a request which **does** supply the Accept header. This can lead to some very unexpected behavior in browsers.
This commit adds the Vary:Accept header for all requests, even if the Accept header is not present in the request. If a format parameter (e.g. `.json` suffix) is included in the path, then the Accept header is still omitted. (The format parameter takes precedence over any Accept: header, so the response is no longer varies based on the Accept header)
Instead of using image-uploader, which relies on the old
UploadMixin, we can now use the uppy-image-uploader which
uses the new UppyUploadMixin which is stable enough and
supports both regular XHR uploads and direct S3 uploads,
controlled by a site setting (default to XHR).
At some point it may make sense to rename uppy-image-uploader
back to image-uploader, once we have gone through plugins
etc. and given a bit of deprecation time period.
This commit also fixes `for_private_message`, `for_site_setting`,
and `pasted` flags not being sent via uppy uploads onto the
UploadCreator, both via regular XHR uploads and also through
external/multipart uploads.
The uploaders changed are:
* site setting images
* badge images
* category logo
* category background
* group flair
* profile background
* profile card background
* FIX: do not display add to calendar for past dates
There is no value in saving past dates into calendar
* FIX: remove postId and move ICS to frontend
PostId is not necessary and will make the solution more generic for dates which doesn't belong to a specific post.
Also, ICS file can be generated in JavaScript to avoid calling backend.
Sometimes administrators want to permanently delete posts and topics
from the database. To make sure that this is done for a good reasons,
administrators can do this only after one minute has passed since the
post was deleted or immediately if another administrator does it.
- Allow the `/presence/get` endpoint to return multiple channels in a single request (limited to 50)
- When multiple presence channels are initialized in a single Ember runloop, batch them into a single GET request
- Introduce the `presence-pretender` to allow easy testing of PresenceChannel-related features
- Introduce a `use_cache` boolean (default true) on the the server-side PresenceChannel initializer. Useful during testing.
It allows saving local date to calendar.
Modal is giving option to pick between ics and google. User choice can be remembered as a default for the next actions.
* FEATURE: Return subcategories on categories endpoint
When using the API subcategories will now be returned nested inside of
each category response under the `subcategory_list` param. We already
return all the subcategory ids under the `subcategory_ids` param, but
you then would have to make multiple separate API calls to fetch each of
those subcategories. This way you can get **ALL** of the categories
along with their subcategories in a single API response.
The UI will not be affected by this change because you need to pass in
the `include_subcategories=true` param in order for subcategories to be
returned.
In a follow up PR I'll add the API scoping for fetching categories so
that a readonly API key can be used for the `/categories.json` endpoint. This
endpoint should be used instead of the `/site.json` endpoint for
fetching a sites categories and subcategories.
* Update PR based on feedback
- Have spec check for specific subcategory
- Move comparison check out of loop
- Only populate subcategory list if option present
- Remove empty array initialization
- Update api spec to allow null response
* More PR updates based on feedback
- Use a category serializer for the subcategory_list
- Don't include the subcategory_list param if empty
- For the spec check for the subcategory by id
- Fix spec to account for param not present when empty
* DEV: Remove HTML setting type and sanitization logic.
We concluded that we don't want settings to contain HTML, so I'm removing the setting type and sanitization logic. Additionally, we no longer allow the global-notice text to contain HTML.
I searched for usages of this setting type in the `all-the-plugins` repo and found none, so I haven't added a migration for existing settings.
* Mark Global notices containing links as HTML Safe.
It was possible to see notifications of other users using routes:
- notifications/responses
- notifications/likes-received
- notifications/mentions
- notifications/edits
We weren't showing anything private (like notifications about private messages), only things that're publicly available in other places. But anyway, it feels strange that it's possible to look at notifications of someone else. Additionally, there is a risk that we can unintentionally leak something on these pages in the future.
This commit restricts these routes.
The all inboxes was introduced in
016efeadf6 but we decided to roll it back
for performance reasons. The main performance challenge here is that PG
has to basically loop through all the PMs that a user is allowed to view
before being able to order by `Topic#bumped_at`. The all inboxes was not
planned as part of the new/unread filter so we've decided not to tackle
the performance issue for the upcoming release.
Follow-up to 016efeadf6
This commit allows for measuring the time taken for
individual uploads via the new uppy interfaces, only
if the enable_upload_debug_mode site setting is enabled.
Also in this PR, for upload errors with a specific message
locally, we return the real message to show in the modal
instead of the upload.failed message so the developer
does not have to dig around in logs.
The file size error messages for max_image_size_kb and
max_attachment_size_kb are shown to the user in the KB
format, regardless of how large the limit is. Since we
are going to support uploading much larger files soon,
this KB-based limit soon becomes unfriendly to the end
user.
For example, if the max attachment size is set to 512000
KB, this is what the user sees:
> Sorry, the file you are trying to upload is too big (maximum
size is 512000KB)
This makes the user do math. In almost all file explorers that
a regular user would be familiar width, the file size is shown
in a format based on the maximum increment (e.g. KB, MB, GB).
This commit changes the behaviour to output a humanized file size
instead of the raw KB. For the above example, it would now say:
> Sorry, the file you are trying to upload is too big (maximum
size is 512 MB)
This humanization also handles decimals, e.g. 1536KB = 1.5 MB
Allows creating a bookmark with the `for_topic` flag introduced in d1d2298a4c set to true. This happens when clicking on the Bookmark button in the topic footer when no other posts are bookmarked. In a later PR, when clicking on these topic-level bookmarks the user will be taken to the last unread post in the topic, not the OP. Only the OP can have a topic level bookmark, and users can also make a post-level bookmark on the OP of the topic.
I had to do some pretty heavy refactors because most of the bookmark code in the JS topics controller was centred around instances of Post JS models, but the topic level bookmark is not centred around a post. Some refactors were just for readability as well.
Also removes some missed reminderType code from the purge in 41e19adb0d
We don't actually use the reminder_type for bookmarks anywhere;
we are just storing it. It has no bearing on the UI. It used
to be relevant with the at_desktop bookmark reminders (see
fa572d3a7a)
This commit marks the column as readonly, ignores it, and removes
the index, and it will be dropped in a later PR. Some plugins
are relying on reminder_type partially so some stubs have been
left in place to avoid errors.
This partially reverts commit ddb458343d.
Seeing performance degrade on larger sites so back to drawing board on
this one. Instead of the DISTINCT LEFT JOIN, we switch back to
IN(subquery).
First reported in https://meta.discourse.org/t/-/202482/19
There are two optimizations being applied here:
1. Fetch a user's group ids in a seperate query instead of including it
as a sub-query. When I tried a subquery, the query plan becomes very
inefficient.
1. Join against the `topic_allowed_users` and `topic_allowed_groups`
table instead of doing an IN against a subquery where we UNION the
`topic_id`s from the two tables. From my profiling, this enables PG to
do a backwards index scan on the `index_topics_on_timestamps_private`
index.
This commit fixes a bug where listing all messages was incorrectly
excluding topics if a topic has been archived by a group even if the
user did not belong to the group.
This commit also fixes another bug where dismissing private messages
selectively was subjected to the default limit of 30.
We don't need no stinkin' denormalization! This commit ignores
the topic_id column on bookmarks, to be deleted at a later date.
We don't really need this column and it's better to rely on the
post.topic_id as the canonical topic_id for bookmarks, then we
don't need to remember to update both columns if the bookmarked
post moves to another topic.
Administrators can use second factor to confirm granting admin access
without using email. The old method of confirmation via email is still
used as a fallback when second factor is unavailable.
The previous excerpt was a simple truncated raw message. Starting with
this commit, the raw content of the draft is cooked and an excerpt is
extracted from it. The logic for extracting the excerpt mimics the the
`ExcerptParser` class, but does not implement all functionality, being
a much simpler implementation.
The two draft controllers have been merged into one and the /draft.json
route has been changed to /drafts.json to be consistent with the other
route names.
When a user archives a personal message, they are redirected back to the
inbox and will refresh the list of the topics for the given filter.
Publishing an event to the user results in an incorrect incoming message
because the list of topics has already been refreshed.
This does mean that if a user has two tabs opened, the non-active tab
will not receive the incoming message but at this point we do not think
the technical trade-offs are worth it to support this feature. We
basically have to somehow exclude a client from an incoming message
which is not easy to do.
Follow-up to fc1fd1b416
At this point in time, we do not think supporting unread and new when an
admin is looking at another user's messages is worth supporting.

PresenceChannel aims to be a generic system for allow the server, and end-users, to track the number and identity of users performing a specific task on the site. For example, it might be used to track who is currently 'replying' to a specific topic, editing a specific wiki post, etc.
A few key pieces of information about the system:
- PresenceChannels are identified by a name of the format `/prefix/blah`, where `prefix` has been configured by some core/plugin implementation, and `blah` can be any string the implementation wants to use.
- Presence is a boolean thing - each user is either present, or not present. If a user has multiple clients 'present' in a channel, they will be deduplicated so that the user is only counted once
- Developers can configure the existence and configuration of channels 'just in time' using a callback. The result of this is cached for 2 minutes.
- Configuration of a channel can specify permissions in a similar way to MessageBus (public boolean, a list of allowed_user_ids, and a list of allowed_group_ids). A channel can also be placed in 'count_only' mode, where the identity of present users is not revealed to end-users.
- The backend implementation uses redis lua scripts, and is designed to scale well. In the future, hard limits may be introduced on the maximum number of users that can be present in a channel.
- Clients can enter/leave at will. If a client has not marked itself 'present' in the last 60 seconds, they will automatically 'leave' the channel. The JS implementation takes care of this regular check-in.
- On the client-side, PresenceChannel instances can be fetched from the `presence` ember service. Each PresenceChannel can be used entered/left/subscribed/unsubscribed, and the service will automatically deduplicate information before interacting with the server.
- When a client joins a PresenceChannel, the JS implementation will automatically make a GET request for the current channel state. To avoid this, the channel state can be serialized into one of your existing endpoints, and then passed to the `subscribe` method on the channel.
- The PresenceChannel JS object is an ember object. The `users` and `count` property can be used directly in ember templates, and in computed properties.
- It is important to make sure that you `unsubscribe()` and `leave()` any PresenceChannel objects after use
An example implementation may look something like this. On the server:
```ruby
register_presence_channel_prefix("site") do |channel|
next nil unless channel == "/site/online"
PresenceChannel::Config.new(public: true)
end
```
And on the client, a component could be implemented like this:
```javascript
import Component from "@ember/component";
import { inject as service } from "@ember/service";
export default Component.extend({
presence: service(),
init() {
this._super(...arguments);
this.set("presenceChannel", this.presence.getChannel("/site/online"));
},
didInsertElement() {
this.presenceChannel.enter();
this.presenceChannel.subscribe();
},
willDestroyElement() {
this.presenceChannel.leave();
this.presenceChannel.unsubscribe();
},
});
```
With this template:
```handlebars
Online: {{presenceChannel.count}}
<ul>
{{#each presenceChannel.users as |user|}}
<li>{{avatar user imageSize="tiny"}} {{user.username}}</li>
{{/each}}
</ul>
```
The generate_presigned_put endpoint for direct external uploads
(such as the one for the uppy-image-uploader) records allowed
S3 metadata values on the uploaded object. We use this to store
the sha1-checksum generated by the UppyChecksum plugin, for later
comparison in ExternalUploadManager.
However, we were not doing this for the create_multipart endpoint,
so the checksum was never captured and compared correctly.
Also includes a fix to make sure UppyChecksum is the last preprocessor to run.
It is important that the UppyChecksum preprocessor is the last one to
be added; the preprocessors are run in order and since other preprocessors
may modify the file (e.g. the UppyMediaOptimization one), we need to
checksum once we are sure the file data has "settled".
Users can invite people to topic and they will be automatically
redirected to the topic when logging in after signing up. This commit
ensures a "invited_to_topic" notification is created when the invite is
redeemed.
The same notification is used for the "Notify" sharing method that is
found in share topic modal.
Since ad3ec5809f when a user chooses
the Dismiss New... option in the New topic list, we send a request
to topics/reset-new.json with ?tracked=false as the only parameter.
This then uses Topic as the scope for topics to dismiss, with no
other limitations. When we do topic_scope.pluck(:id), it gets the
ID of every single topic in the database (that is not deleted) to
pass to TopicsBulkAction, causing a huge query with severe performance
issues.
This commit changes the default scope to use
`TopicQuery.new(current_user).new_results(limit: false)`
which should only use the topics in the user's New list, which
will be a much smaller list, depending on the user's "new_topic_duration_minutes"
setting.
There are certain design decisions that were made in this commit.
Private messages implements its own version of topic tracking state because there are significant differences between regular and private_message topics. Regular topics have to track categories and tags while private messages do not. It is much easier to design the new topic tracking state if we maintain two different classes, instead of trying to mash this two worlds together.
One MessageBus channel per user and one MessageBus channel per group. This allows each user and each group to have their own channel backlog instead of having one global channel which requires the client to filter away unrelated messages.
This pull request introduces the endpoints required, and the JavaScript functionality in the `ComposerUppyUpload` mixin, for direct S3 multipart uploads. There are four new endpoints in the uploads controller:
* `create-multipart.json` - Creates the multipart upload in S3 along with an `ExternalUploadStub` record, storing information about the file in the same way as `generate-presigned-put.json` does for regular direct S3 uploads
* `batch-presign-multipart-parts.json` - Takes a list of part numbers and the unique identifier for an `ExternalUploadStub` record, and generates the presigned URLs for those parts if the multipart upload still exists and if the user has permission to access that upload
* `complete-multipart.json` - Completes the multipart upload in S3. Needs the full list of part numbers and their associated ETags which are returned when the part is uploaded to the presigned URL above. Only works if the user has permission to access the associated `ExternalUploadStub` record and the multipart upload still exists.
After we confirm the upload is complete in S3, we go through the regular `UploadCreator` flow, the same as `complete-external-upload.json`, and promote the temporary upload S3 into a full `Upload` record, moving it to its final destination.
* `abort-multipart.json` - Aborts the multipart upload on S3 and destroys the `ExternalUploadStub` record if the user has permission to access that upload.
Also added are a few new columns to `ExternalUploadStub`:
* multipart - Whether or not this is a multipart upload
* external_upload_identifier - The "upload ID" for an S3 multipart upload
* filesize - The size of the file when the `create-multipart.json` or `generate-presigned-put.json` is called. This is used for validation.
When the user completes a direct S3 upload, either regular or multipart, we take the `filesize` that was captured when the `ExternalUploadStub` was first created and compare it with the final `Content-Length` size of the file where it is stored in S3. Then, if the two do not match, we throw an error, delete the file on S3, and ban the user from uploading files for N (default 5) minutes. This would only happen if the user uploads a different file than what they first specified, or in the case of multipart uploads uploaded larger chunks than needed. This is done to prevent abuse of S3 storage by bad actors.
Also included in this PR is an update to vendor/uppy.js. This has been built locally from the latest uppy source at d613b849a6. This must be done so that I can get my multipart upload changes into Discourse. When the Uppy team cuts a proper release, we can bump the package.json versions instead.
