`emailOrUsername` was renamed to `invitee` in a recent change to app/assets/javascripts/discourse/app/components/invite-panel.js and needed to be updated in client.en.yml
Issue originally reported in https://meta.discourse.org/t/bypass-sso-by-adding-unkown-email-to-group/177339
Inviting people via email address to a group when SSO is enabled (or local logins are disabled) led to a situation where user records were being created bypassing single sign-on.
We already prevent that in most places. This adds required checks to `GroupsController`.
This pull requests contains a series of improvements to groups
settings and member management such as:
- Showing which users have set a group as primary
- Moving similar settings together under Effects
- Adding bulk select and actions to members page
This PR revamps the topic timer UI, using the time shortcut selector from the bookmark modal.
* Fixes an issue where the duration of hours/days after last reply or auto delete replies was not enforced to be > 0
* Fixed an issue where the timer dropdown options were not reloaded correctly if the topic status changes in the background (use `MessageBus` to publish topic state in the open/close timer jobs)
* Moved the duration input and the "based on last post" option from the `future-date-input` component, as it was only used for topic timers. Also moved out the notice that is displayed which was also only relevant for topic timers.
Bootsnap started printing these warnings:
```
[DEPRECATED] Bootsnap's `autoload_paths_cache:` option is deprecated and will be removed. If you use Zeitwerk this option is useless, and if you are still using the classic autoloader upgrading is recommended.
[DEPRECATED] Bootsnap's `disable_trace:` option is deprecated and will be removed. If you use Ruby 2.5 or newer this option is useless, if not upgrading is recommended.
```
Disabling shared drafts used to leave topics in an inconsistent state
where they were not displayed as shared drafts and thus there was no
way of publishing them. Moreover, they were accessible just to users
who have permissions to create shared drafts.
This commit adds another permission check that is used for most
operations and the old can_create_shared_draft? remains used just when
creating a new shared draft.
This PR is the first step towards replacing our `{{user-selector}}` and eventually deprecating and removing it from our codebase. Some of `{{user-selector}}` problems are:
1. It's called `{{user-selector}}`, but in reality in can also select groups and emails.
2. It's an Ember component, yet it doesn't have a handlebars template and uses jQuery to render itself and modify the DOM. An example of this problem is when you want to clear the selected users programmatically, see [this](6c155dba77/app/assets/javascripts/discourse/app/components/user-selector.js (L179-L185)).
3. We now have select kit which does very similar things but a lot better.
This PR introduces `{{email-group-user-chooser}}` which is meant to replace `{{user-selector}}`. It extends select kit and has the same features that `{{user-selector}}` has. `{{user-selector}}` is still used in a few places in core, but they'll all be replaced with the new component in a separate commit.
Once `{{user-selector}}` is not used anywhere in core, it'll be deprecated and then removed after the 2.7 release.
This PR moves all of the time picking functionality from the bookmark modal and controller into a reusable time-shortcut-picker component, which will be used for the topic timer UI revamp. All of the utility JS for getting dates like tomorrow/next week/next month etc. have also been moved into a separate utility lib.
The time-shortcut-picker has a couple of options that can be passed in:
* prefilledDatetime - The date and time to parse and prefill into the custom date and time section, useful for editing interfaces.
* onTimeSelected (callback) - Called when one of the time shortcuts is clicked, and passes the type of the shortcut (e.g. tomorrow) and the datetime selected.
* additionalOptionsToShow - An array of option ids to show (by default `later_today` and `later_this_week` are hidden)
* hiddenOptions - An array of option ids to hide
* customOptions - An array of custom options to display (e.g. the option to select a post date for the bookmarks modal). The options should have the below properties:
* id
* icon
* label (I18n key)
* time (moment datetime object)
* timeFormatted
* hidden
The other major work in this PR is moving all of the bookmark functionality out of the bookmark modal controller and into its own component, where it makes more sense to be able to access elements on the page via `document`. Tests have been added to accompany this move, and existing acceptance tests for bookmark are all passing.
Adds a new column/setting to groups, allow_unknown_sender_topic_replies, which is default false. When enabled, this scenario is allowed via IMAP:
* OP sends an email to the support email address which is synced to a group inbox via IMAP, creating a group topic
* Group user replies to the group topic
* An email notification is sent to the OP of the topic via GroupSMTPMailer
* The OP has several email accounts and the reply is sent to all of them, or they forward their reply to another email account
* The OP replies from a different email address than the OP (gloria@gmail.com instead of gloria@hey.com for example)
* The a new staged user is created, the new reply is accepted and added to the topic, and the staged user is added to the topic allowed users
Without allow_unknown_sender_topic_replies enabled the new reply creates an entirely new topic (because the email address it is sent from is not previously part of the topic email chain).
Background: I wanted to see `categories.latest_by` translation in context in a live app but couldn't find it, so I traced it throughout the code.
My step-by-step reasoning for the removal is:
1. `categories-only` does not use `latestTopicOnly`, so there's no need to call it with that argument
2. `parent-category-row` is never called with `latestTopicOnly` argument, so the reference to that arg can be removed from its template
3. after that, `featured-topic` is now no longer ever called with `latestTopicOnly` argument (except in the `ghost` theme, but that's because its override of `categories-only` template 4e2fba963c/common/header.html (L119) is based on the old version of that template from core), so it seems safe to remove it there too (`categories.latest_by` i18n string is also no longer needed)
4. then, nothing is using `latestTopicOnly` anymore so it can be removed from `categories` hbs/js
I checked in each step that there are no plugins or themes (in all-the-plugins/all-the-themes) using those properties/arguments/strings.
- Improve warning message.
- Only display the warning if the language has a fallback and either "allow_user_locale", or "set_locale_from_accept_language_header" are enabled.
This adds a new table UserNotificationSchedules which stores monday-friday start and ends times that each user would like to receive notifications (with a Boolean enabled to remove the use of the schedule). There is then a background job that runs every day and creates do_not_disturb_timings for each user with an enabled notification schedule. The job schedules timings 2 days in advance. The job is designed so that it can be run at any point in time, and it will not create duplicate records.
When a users saves their notification schedule, the schedule processing service will run and schedule do_not_disturb_timings. If the user should be in DND due to their schedule, the user will immediately be put in DND (message bus publishes this state).
The UI for a user's notification schedule is in user -> preferences -> notifications. By default every day is 8am - 5pm when first enabled.
Admins can now edit translations in different languages without having to change their locale. We display a warning when there's a fallback language set.
Background: RFC 8314 3.3 asks that:
clients and servers SHOULD implement both STARTTLS on
port 587 and Implicit TLS on port 465
Discourse currently cannot be configured this way.
With this patch, it's possible to set
DISCOURSE_SMTP_FORCE_TLS=true to use implicit TLS on port 465
Feature for `Must Approve Users` setup. When a user is rejected, a staff member can optionally set a reason for audit purposes. In addition, feedback email can be sent to the user.

Installing multiple copies of the same theme/component is possible, but you rarely need to actually have multiple copies installed. We've seen many times new admins installing duplicates of components because they were unaware it was already installed. This PR makes the theme installer modal loop through the existing themes when you click on 'install', and if there is a theme with a URL that matches the URL you entered, a warning will show up and you will need to click 'install' again to proceed.
osts from topics with 'auto delete replies timer' with more than
skip_auto_delete_reply_likes likes will no longer be deleted. If 0,
all posts will be deleted.
This allows plugins to call `register_demon_process` with a Class inheriting from Demon::Base. The unicorn master process will take care of spawning, monitoring and restarting the process. This API should be used with extreme caution, but it is significantly cleaner than spawning processes/threads in an `after_initialize` block.
This commit also cleans up the demon spawning logging so that it uses the same format as unicorn worker logging. It also switches to the block form of `fork` to ensure that Demons exit after running, rather than returning execution to where the fork took place.
Include the enable_filtered_replies_view site setting in the admin UI

Fixes grammar for "Viewing 1 reply to..." label
Being that system badges ship with every instance of Discourse, we've opted to define the name, description, and long description in our locales files to promote translation into other languages. When an admin visited the overview page of a system badge in their admin panel, they were met with disabled inputs for these text properties. The problem is that we failed to educate the admin that the text needs to be managed via the site text customization settings.
This change adds a small "Customize Text" link under theses inputs that takes the admin to the specific site text customization where they can make desired changes.
You can let non-staff users use shared drafts by modifying the `shared_drafts_min_trust_level` site setting. These users must have access to the shared draft category.
* FIX: show/hide ignored users preferences
based on the current user trust level and the appropriate site setting.
* Allow us to await the `updateCurrentUser` call

Force pushing a commit to a theme repository used to break the updater,
because the system was not able to count the commits behind the old and
new version. This operation failed because a force push deleted the old
commits.
The user was prompted with a simple "500 server error" message.
This adds a new min_trust_level_to_allow_ignore site setting that enables admins to control the point at which a user is allowed to ignore other users.
* FEATURE: display error if Oneboxing fails due to HTTP error
- display warning if onebox URL is unresolvable
- display warning if attributes are missing
* FEATURE: Use new Instagram oEmbed endpoint if access token is configured
Instagram requires an Access Token to access their oEmbed endpoint. The requirements (from https://developers.facebook.com/docs/instagram/oembed/) are as follows:
- a Facebook Developer account, which you can create at developers.facebook.com
- a registered Facebook app
- the oEmbed Product added to the app
- an Access Token
- The Facebook app must be in Live Mode
The generated Access Token, once added to SiteSetting.facebook_app_access_token, will be passed to onebox. Onebox can then use this token to access the oEmbed endpoint to generate a onebox for Instagram.

Themes marked for auto update will be automatically updated when
Discourse is updated. This is triggered by discourse_docker or
docker_manager running Rake task 'themes:update'.
This makes it much easier to check the staff action logs for a specific site setting. A small history icon will appear when hovering over a site setting name. On click, you will be taken to the pre-filtered staff action log for the site setting.
this copy is also shown when viewing invite tabs of other users, so the instructions don't make sense in all cases. shortened it to just say "No invitations to display on this page." users can discover this on their own.
It used to simply say "title is invalid" without giving any hint what
the problem could be. This commit adds different errors messages for
all caps titles, low entropy titles or titles with very long words.
- Bump rails_failover for new per-backend callback feature
- If the master backend fails over, make all sites readonly. And vice-versa for fallback
- If a single backend fails over, make that individual site readonly. And vice-versa for fallback
- When a single backend fails, also check connection to the master backend
Previously, `/u/by-external/{id}` would only work for 'Discourse SSO' systems. This commit adds a new 'provider' parameter to the URL: `/u/by-external/{provider}/{id}`
This is compatible with all auth methods which have migrated to the 'ManagedAuthenticator' pattern. That includes all core providers, and also popular plugins such as discourse-oauth2-basic and discourse-openid-connect.
The new route is admin-only, since some authenticators use sensitive information like email addresses as the external id.
Per Google, sites are encouraged to upgrade from Universal Analytics v3 `analytics.js` to v4 `gtag.js` for Google Analytics tracking. We're giving admins the option to stay on the v3 API or migrate to v4. Admins can change the implementation they're using via the `ga_version` site setting. Eventually Google will deprecate v3, but our implementation gives admins the choice on what to use for now.
We chose this implementation to make the change less error prone, as many site admins are using custom events via the v3 UA API. With the site stetting defaulted to `v3_analytics`, site analytics won't break until the admin is ready to make the migration.
Additionally, in the v4 implementation, we do not enable automatic pageview tracking (on by default in the v4 API). Instead we rely on Discourse's page change API to report pageviews on transition to avoid double-tracking.
It used to simply say "not allowed" without giving any hint what the
problem could be. This commit refactors the code and tries to improve
readability.
There are issues around displaying images on published pages when secure media is enabled. This PR temporarily makes it appear as if published pages are enabled if secure media is also enabled.
Discourse used to break from convention by logging out all sessions on any
specific session logout.
This would leave users confused about why mobile is logged out when the user
logged out of desktop.
log_out_strict is too conservative for most and not the pattern the industry
has adopted (google/twitter/facebook all perform no strict logouts)
When the linked topic is created we'll not hardcode the topic title and
let onebox work its magic instead so that the title can be updated
automatically.
Users could be silenced or suspended by two staff members at the same time and
would not be aware of it. This commit shows an error message if another penalty
has been applied.
This commit adds a site setting `auto_close_topics_create_linked_topic`
which when enabled works in conjunction with `auto_close_topics_post_count`
setting and creates a new linked topic for the topic just closed.
The auto-created new topic contains a link for all the previous topics
and the topic titles are appended with `(Part {n})`.
The setting is enabled by default.
We remove the slow mode composer message and provide better messages when rejecting new posts and edits. The client now validates if the user tries to post again immediately. Finally, we replaced the `hourglass-end` icon with the `hourglass-start` one.
This reverts commit e3de45359f.
We need to improve out strategy by adding a cache breaker with this change ... some assets on CDNs and clients may have incorrect CORS headers which can cause stuff to break.
When `must_approve_users` is enabled then staff users assume that all
users will have to be approved manually. But in case of invite we
auto-approve users if they are invited by users. This commit adds an
info on the bottom of invite modal informing staff users that new users
will be auto-approved as soon as they accept invite.
Most proxies out there will work with chunked encoding transfer. However
some proxies buffer, causing large delays which in turn force the message
bus client to disable chunked encoding. This wastes a request to the message
bus causing superfluous load on the server.
Also
- enableLongPolling is already default true in the client, no need to set it
- remove confusing comment about zepto
Before deleting a topic that has a high number of views (default of 5000), the user will be prompted with a confirmation popup. This works for all delete buttons on the topic located in: topic-timeline, topic-admin-menu, topic-footer-buttons, and post-menu if the post's ID is 1.
The delete button will be disabled while deletion is in progress, to prevent any unwanted behavior.
A site setting is also available to change the minimum amount of views required to display the confirmation popup.
All kudos are going to @RickyC0626. I only rebased with master and added few qunit tests to ensure that this feature works as expected.
Original PR: #10459
New version of Thunderbird email client reimplemented PGP support. Now the following attachments are added by default, if email signatures are enabled:
* OpenPGP_0x(pgp key id).asc
* OpenPGP_signature(.asc)
The last one has `name="OpenPGP_signature.asc"` in `Content-Type` but `filename="OpenPGP_signature"` (without extension) in `Content-Disposition: attachment`.
Since both the key and the signature have proper MIME types, filter them by default.

* FEATURE - Add SiteSettings to control JPEG image quality
`recompress_original_jpg_quality` - the maximum quality of a newly
uploaded file.
`image_preview_jpg_quality` - the maximum quality of OptimizedImages
Showing this button is confusing for sites which are using external authentication. Clicking 'log in' already pops up the login modal, which includes a forgot password link when appropriate.
This PR introduces a feature that will detect a date inside the post that a user is bookmarking, and offer that date as an option in the bookmark modal.
The logic is that we get the first date/time detected in the post. If it does not have a time, just a date, then we default to 8:00am for the time.
If RAILS_DISABLE_ACTIVERECORD_LOGS=1 is passed when starting Rails, none of the query log output will show. This is very useful for debugging with breakpoints because logs are not flooding in constantly.
* FIX: Ensure slow mode duration is correctly edited and displayed.
This commit fixes a bug where you were forced to set hours, minutes, and seconds or you won't be able to set the slow mode. Also, the duration was not displayed correctly due to the seconds not being truncated.
Additionally, we'll always display the hours, minutes, and seconds inputs for clarity and remove the blue banner.
* Set slow mode modal tweaks.
Uses labels instead of placeholders.
Input fields only visible when custom option selected.
Replace "Custom Duration" with "Pick Duration".
Additionally, place the `Set slow mode` button at the bottom of the topic actions menu.
* Perform the slow_mode validation also on the client-side before saving trying to save the post. This way, the post won't be staged.
This was made adjustable to allow rolling back quickly if problems came
up. The new behaviour was made default in 93137066 and no problems with
this have been reported.
Adds a new slow mode for topics that are heating up. Users will have to wait for a period of time before being able to post again.
We store this interval inside the topics table and track the last time a user posted using the last_posted_at datetime in the TopicUser relation.
Dependency on gifsicle, allow_animated_avatars and allow_animated_thumbnails
site settings were all removed. Animated GIF images are still allowed, but
the generated optimized images are no longer animated for those (which were
used for avatars and thumbnails).
The added 'animated' is populated by extracting information using FastImage.
This field was used to selectively reoptimize old animations. This process
happens in the background.
* FEATURE: add penalty options for take action
Add the ability to silence or suspend users from the "take action"
button when moderators are flagging posts. This allows for a more streamlined
active moderation workflow, when moderating against a topic directly.
Now that we have support for user-selectable color schemes, it makes sense
to simplify seeding and theme updates in the wizard.
We now:
- seed only one theme, named "Default" (previously "Light")
- seed a user-selectable Dark color scheme
- rename the "Themes" wizard step to "Colors"
- update the default theme's color scheme if a default is set
(a new theme is created if there is no default)
Per Google, sites are encouraged to upgrade from `analytics.js` to `gtag.js` for Google Analytics tracking. This commit updates core Discourse to use the new `gtag.js` API Google is asking sites to use. This API has feature parity with `analytics.js` but does not use trackers.
When the server gets overloaded and lots of requests start queuing server
will attempt to shed load by returning 429 errors on background requests.
The client can flag a request as background by setting the header:
`Discourse-Background` to `true`
Out-of-the-box we shed load when the queue time goes above 0.5 seconds.
The only request we shed at the moment is the request to load up a new post
when someone posts to a topic.
We can extend this as we go with a more general pattern on the client.
Previous to this change, rate limiting would "break" the post stream which
would make suggested topics vanish and users would have to scroll the page
to see more posts in the topic.
Server needs this protection for cases where tons of clients are navigated
to a topic and a new post is made. This can lead to a self inflicted denial
of service if enough clients are viewing the topic.
Due to the internal security design of Discourse it is hard for a large
number of clients to share a channel where we would pass the full post body
via the message bus.
It also renames (and deprecates) triggerNewPostInStream to triggerNewPostsInStream
This allows us to load a batch of new posts cleanly, so the controller can
keep track of a backlog

* FIX: second factor cannot be enabled if SSO is enabled
If `enable_sso` setting is enabled then admin should not be able to

To avoid blocking the sidekiq queue a limit of 10,000 digests per 30 minutes
is introduced.
This acts as a safety measure that makes sure we don't keep pouring oil on
a fire.
On multisites it is recommended to set the number way lower so sites do not
dominate the backlog. A reasonable default for multisites may be 100-500.
This can be controlled with the environment var
DISCOURSE_MAX_DIGESTS_ENQUEUED_PER_30_MINS_PER_SITE
See https://meta.discourse.org/t/changing-a-users-email/164512 for additional context.
Previously when an admin user changed a user's email we assumed that they would need a password reset too because they likely did not have access to their account. This proved to be incorrect, as there are other reasons a user needs admin to change their email. This PR:
* Changes the admin change email for user flow so the user is sent an email to confirm the change
* We now record who the email change request was requested by
* If the requested by user is admin and not the user we note this in the email sent to the user
* We also make the confirm change email route open to anonymous users, so it can be clicked by the user even if they do not have access to their account. If there is a logged in user we make sure the confirmation matches the current user.
Allows site administrators to pick different fonts for headings in the wizard and in their site settings. Also correctly displays the header logos in wizard previews.
Previously this site setting `embed unlisted` defaulted to false and
empty topics would be generated for embed, but those topics tend to take
up a lot of room on the topic lists.
This new default creates invisible topics by default until they receive
their first reply.
This is where they should be as far as ember is concerned. Note this is
a huge commit and we should be really careful everything continues to
work properly.
See https://meta.discourse.org/t/changing-a-users-email/164512 for context.
When admin changes an email for a user, we were incorrectly sending the password reset email to the user's old address. Also the new email does not come into effect until the reset password process is done, so this PR adds some notes to the admin to make this clearer.
This allows administrators to stop automatic redirect to an external authenticator. It only takes effect when there is a single authentication method, and the site is login_required
It's a more user-friendly alternative to the default select-kit list,
for settings that are simple lists of items (the regular list widget is
better for settings with choice options).
The site setting `search_recent_posts_size` controls the window of posts
that we will search through before trying to search through the full index
If this number is too low then the search quality can suffer a lot as recent
posts may dominate search. If the number is too high then performance will
suffer.
This attempts to find a happy medium, 1 million posts will cover the majority
of forums out there and should perform adequately.
Use the names as provided by discourse-fonts and remove the
translated strings.
It also ensures that the selected font is present in case a font will
be removed in the future.
This is a little bit of refactoring. Core Discourse should have default promotion message for TL2.
In addition, when the Discobot plugin is enabled, the user is invited to advanced training
It didn't provide much value to users as it often didn't match the number visible in the topic timeline. That's because `postNumber` is an implementation detail, while the timeline counts only full visible posts (no whispers, topic action notices, etc.)
To check if a post contains any embedded media, we look if the "image_sizes" attribute is present in the new post manager arguments.
We want to see one boxed links, but we only store the raw content of the post. To work around this, I extracted the onebox logic from the composer editor into a module.
We are making the changes from the PR #10563 the default behaviour. Now, if secure media is enabled, secure images will be embedded in emails by default instead of redacting them and displaying a message. This will be a nicer overall experience by default, and for forums that want to be super strict with redaction this setting can always be disabled.
This PR removes the user reminder topic timers, because that system has been supplanted and improved by bookmark reminders. The option is removed from the UI and all existing user reminder topic timers are migrated to bookmark reminders.
Migration does this:
* Get all topic_timers with status_type 5 (reminders)
* Gets all bookmarks where the user ID and topic ID match
* Loops through the found topic timers
* If there is no bookmark for the OP of the topic, then we just create a bookmark with a reminder
* If there is a bookmark for the OP of the topic and it does **not** have a reminder set, then just
update it with the topic timer reminder
* If there is a bookmark for the OP of the topic with a reminder then just discard the topic timer
* Cancels all outstanding user reminder topic timers
* **Trashes (not deletes) all user reminder topic timers**
Notes:
* For now I have left the user reminder topic timer job class in place; this is so the jobs can be cancelled in the migration. It and the specs will be deleted in the next PR.
* At a later date I will write a migration to delete all trashed user topic timers. They are not deleted here in case there are data issues and they need to be recovered.
* A future PR will change the UI of the topic timer modal to make it look more like the bookmark modal.
In some cases Discourse admins may opt for sessions not to persist when a
browser is closed.
This is particularly useful in healthcare and education settings where
computers are shared among multiple workers.
By default `persistent_sessions` site setting is enabled, to opt out you
must disable the site setting.
Currently, if a group's visibility is set to "Group owners, members" then the mods can't view those group pages. The same rule is applied for members visibility setting too.
This reverts commit 7fc7090. And fixed the spec test fails.
Currently, if a group's visibility is set to "Group owners, members" then the mods can't view those group pages. The same rule is applied for members visibility setting too.
This PR introduces a few important changes to secure media redaction in emails. First of all, two new site settings have been introduced:
* `secure_media_allow_embed_images_in_emails`: If enabled we will embed secure images in emails instead of redacting them.
* `secure_media_max_email_embed_image_size_kb`: The cap to the size of the secure image we will embed, defaulting to 1mb, so the email does not become too big. Max is 10mb. Works in tandem with `email_total_attachment_size_limit_kb`.
`Email::Sender` will now attach images to the email based on these settings. The sender will also call `inline_secure_images` in `Email::Styles` after secure media is redacted and attachments are added to replace redaction messages with attached images. I went with attachment and `cid` URLs because base64 image support is _still_ flaky in email clients.
All redaction of secure media is now handled in `Email::Styles` and calls out to `PrettyText.strip_secure_media` to do the actual stripping and replacing with placeholders. `app/mailers/group_smtp_mailer.rb` and `app/mailers/user_notifications.rb` no longer do any stripping because they are earlier in the pipeline than `Email::Styles`.
Finally the redaction notice has been restyled and includes a link to the media that the user can click, which will show it to them if they have the necessary permissions.
