This commit introduces a new site setting: `block_hotlinked_media`. When enabled, all attempts to hotlink media (images, videos, and audio) will fail, and be replaced with a linked placeholder. Exceptions to the rule can be added via `block_hotlinked_media_exceptions`.
`download_remote_image_to_local` can be used alongside this feature. In that case, hotlinked images will be blocked immediately when the post is created, but will then be replaced with the downloaded version a few seconds later.
This implementation is purely server-side, and does not impact the composer preview.
Technically, there are two stages to this feature:
1. `PrettyText.sanitize_hotlinked_media` is called during `PrettyText.cook`, and whenever new images are introduced by Onebox. It will iterate over all src/srcset attributes in the post HTML and check if they're allowed. If not, the attributes will be removed and replaced with a `data-blocked-hotlinked-src(set)` attribute
2. In the `CookedPostProcessor`, we iterate over all `data-blocked-hotlinked-src(set)` attributes and check whether we have a downloaded version of the media. If yes, we update the src to use the downloaded version. If not, the entire media element is replaced with a placeholder. The placeholder is labelled 'external media', and is a link to the offsite media.
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.
Meta topic: https://meta.discourse.org/t/prevent-to-linkify-when-there-is-a-redirect/226964/2?u=osama.
This commit adds a new site setting `block_onebox_on_redirect` (default off) for blocking oneboxes (full and inline) of URLs that redirect. Note that an initial http → https redirect is still allowed if the redirect location is identical to the source (minus the scheme of course). For example, if a user includes a link to `http://example.com/page` and the link resolves to `https://example.com/page`, then the link will onebox (assuming it can be oneboxed) even if the setting is enabled. The reason for this is a user may type out a URL (i.e. the URL is short and memorizable) with http and since a lot of sites support TLS with http traffic automatically redirected to https, so we should still allow the URL to onebox.
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.
Currently the only way to allow tagging on pms is to use the `allow_staff_to_tag_pms` site setting. We are removing that site setting and replacing it with `pm_tags_allowed_for_groups` which will allow for non staff tagging. It will be group based permissions instead of requiring the user to be staff.
If the existing value of `allow_staff_to_tag_pms` is `true` then we include the `staff` groups as a default for `pm_tags_allowed_for_groups`.
This was causing issues on some sites, having the const, because this really is heavily
dependent on upload speed. We request 5-10 URLs at a time with this endpoint; for
a 1.5GB upload with 5mb parts this could mean 60 requests to the server to get all
the part URLs. If the user's upload speed is super fast they may request all 60
batches in a minute, if it is slow they may request 5 batches in a minute.
The other external upload endpoints are not hit as often, so they can stay as constant
values for now. This commit also increases the default to 20 requests/minute.
When an admin enters a badly formed regular expression in the
permalink_normalizations site setting, a RegexpError exception is
generated everytime a URL is normalized (see Permalink.normalize_url).
The new validator validates every regular expression present in the
setting value (delimited by '|').
This commit introduces a new site setting: `use_name_for_username_suggestions` (default true)
Admins can disable it if they want to stop using Name values when generating usernames for users. This can be useful if you want to keep real names private-by-default or, when used in conjunction with the `use_email_for_username_and_name_suggestions` setting, you would prefer to use email-based username suggestions.

This PR enables custom email dark mode styles by default that were added here.
There is currently poor support for dark mode queries in mail clients. The main beneficiary of these changes will be Apple Mail and Outlook.
Enjoy the darkness 🕶️
* 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`.
Due to default CSP web workers instantiated from CDN based assets are still
treated as "same-origin" meaning that we had no way of safely instansiating
a web worker from a theme.
This limits the theme system and adds the arbitrary restriction that WASM
based components can not be safely used.
To resolve this limitation all js assets in about.json are also cached on
local domain.
{
"name": "Header Icons",
"assets" : {
"worker" : "assets/worker.js"
}
}
This can then be referenced in JS via:
settings.theme_uploads_local.worker
local_js_assets are unconditionally served from the site directly and
bypass the entire CDN, using the pre-existing JavascriptCache
Previous to this change this code was completely dormant on sites which
used s3 based uploads, this reuses the very well tested and cached asset
system on s3 based sites.
Note, when creating local_js_assets it is highly recommended to keep the
assets lean and keep all the heavy working in CDN based assets. For example
wasm files can still live on the CDN but the lean worker that loads it can
live on local.
This change unlocks wasm in theme components, so wasm is now also allowed
in `theme_authorized_extensions`
* more usages of upload.content
* add a specific test for upload.content
* Adjust logic to ensure that after upgrades we still get a cached local js
on save
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.
We rolled out a change to disable canonical indexing.
The goal behind it was to limit crawl budget by Google being spent
scanning non canonical topic links.
Since this change was applied we rolled out 2 fixes that made the change
no longer needed.
1. Topic RSS feeds are no longer followed, links in the RSS feeds are
not followed.
2. Post RSS feeds now contain canonical links.
Combined these two changes mean crawlers no longer discover a large
amount on non-canonical links on Discourse sites.
* 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

Similar site settings exist for likes and edits and the new ones work
in a similar way.
By default, users below TL2 have a limit of 20, the limit is increased
by 1.5 for TL2 users up to 30, by 2 for TL3 users up to 40 and by 3 for
TL4 users up to 60.
The 5s difference was causing anon clients to have ~5s gaps between their long-polling requests. On busy sites, this could be enough time for them to build up a backlog, which then becomes much more expensive for us on the server-side.
Breakdown of fixes in this commit:
* `UserStat#topic_count` was not updated when visibility of
the topic changed.
* `UserStat#post_count` was not updated when post was hidden or
unhidden.
* `TopicConverter` was only incrementing or decrementing the counts by 1
even if a user has multiple posts in the topic.
* The commit turns off the verbose logging by default as it is just
noise to normal users who are not debugging this problem.
* Chinese segmenetation will continue to rely on cppjieba
* Japanese segmentation will use our port of TinySegmenter
* Korean currently does not rely on segmentation which was dropped in c677877e4f
* SiteSetting.search_tokenize_chinese_japanese_korean has been split
into SiteSetting.search_tokenize_chinese and
SiteSetting.search_tokenize_japanese respectively
- 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
The previous default aspect ratio for cropping tall images was a little
too strict and was cutting off images. This new setting should allow for
a larger range of image sizes before cropping them.
This commit removes the enable_experimental_backup_uploader site
setting and the flags in backups-index.hbs to make the uppy
backup uploader the main one from now on.
A follow-up commit will delete the old backup uploader code and
also remove resumable.js from the project.
* 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
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.

This is a big change to change over to using the uppy
upload mixin in the composer by default. This gets rid
of the temporary composer-editor-uppy component, as well
as removing the old ComposerUpload mixin and copying over
any missing functions that were not yet implemented by
ComposerUploadUppy. This has been working well on our
hosting for some time now and has led us to several
bug fixes.
This commit also deletes the old plugin API for adding
preprocessors for the uploads. The accepted method of doing
this now is via an uppy preprocessor plugin, which we have
several examples of in the core codebase.
Leaving the `enable_experimental_composer_uploader` site setting
intact for now because some plugins still rely on it, this
will be removed at a later date.
One step closer to ending the jQuery file uploader saga...
* FEATURE: Optionally send a 'noindex' header in non-canonical responses
This will be used in a SEO experiment.
Co-authored-by: David Taylor <david@taylorhq.com>
When this setting is turned on, it will check that normalized emails
are unique. Normalized emails are emails without any dots or plus
aliases.
This setting can be used to block use of aliases of the same email
address.
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
will be notified.
* FEATURE: Always show advanced invite options
The UI is more simple and more efficient than how it was when the
advanced options toggle was introduced. It does not make sense to keep
it anymore.
* UX: Minor copy edits
* UX: Merge expire invite controls
There were two controls in the create invite modal. One was a static
text that displayed how much time is left until the invite expires. The
other one was a datetime selector that set the time the invite expires.
This commit merges the two controls in a single one: staff users will
continue to see the datetime selector without the static text and
regular users will only see the static text because they cannot set
when the invite expires.
* UX: Remove invite link
It should only be visible after the invite was created.
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.
