We had an issue where onebox thumbnail was too large and thus was optimized, and we are using the image URLs in post to redact and re-embed, based on the sha1 in the URL. Optimized image URLs have extra stuff on the end like _99x99 so we were not parsing out the sha1 correctly. Another issue I found was for posts that have giant images, the original was being used to embed in the email and thus would basically never get included because it is huge.
For example the URL 787b17ea61_2_690x335.jpeg was not parsed correctly; we would end up with 787b17ea6140f4f022eb7f1509a692f2873cfe35_2_690x335.jpeg as the sha1 which would not find the image to re-embed that was already attached to the email.
This fix will use the first optimized image of the detected upload when we are redacting and then re-embedding to make sure we are not sending giant things in email. Also, I detect if it is a onebox thumbnail or the site icon and force appropriate sizes and styles.
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.
There is a site setting reply_by_email_enabled which when combined with reply_by_email_address creates a Reply-To header in emails in the format "test+%{reply_key}@test.com" along with a PostReplyKey record, so when replying Discourse knows where to route the reply.
However this conflicts with the IMAP implementation. Since we are sending the email for a group via SMTP and from their actual email account, we want all replys to go to that email account as well so the IMAP sync job can pick them up and put them in the correct place. So if the group has IMAP enabled and configured, then the reply-to header will be correct.
This PR also makes a further fix to 64b0b50 by using the correct recipient user for the PostReplyKey record. If the post user is used we encounter this error:
if destination.user_id != user.id && !forwarded_reply_key?(destination, user)
raise ReplyUserNotMatchingError, "post_reply_key.user_id => #{destination.user_id.inspect}, user.id => #{user.id.inspect}"
end
This is because the user above is found from the from_address, but the destination which is the PostReplyKey is made by the post.user, which will be different people.
When plugin spec is evaluated for the first time, it took 30 seconds to run:
```
rm -rf tmp/* && LOAD_PLUGINS=1 be rspec ./plugins/discourse-solved/spec/requests/topics_controller_spec.rb
```
Applying sprocket patch in test environment solves that issue
On forums with a large amount of posts when a user had a bookmark in the topic, PostgreSQL was using an inefficient query plan to fetch the first post of the topic. When running this ActiveRecord query:
```
topic.posts.with_deleted.where(post_number: 1).first
```
The following query plan was produced:
```
Limit (cost=0.43..583.49 rows=1 width=891) (actual time=3850.515..3850.515 rows=1 loops=1)
-> Index Scan using posts_pkey on posts (cost=0.43..391231.51 rows=671 width=891) (actual time=3850.514..3850.514
rows=1 loops=1)
Filter: ((topic_id = 160918) AND (post_number = 1))
Rows Removed by Filter: 2274520
Planning time: 0.200 ms
Execution time: 3850.559 ms
(6 rows)
```
The issue here is the combination of ORDER BY and LIMIT causing the ineficcient Index Scan using posts_pkey on posts to be used. When we correct the AR call to this:
```
topic.posts.with_deleted.find_by(post_number: 1)
```
We end up with a query that still has a LIMIT but no ORDER BY, which in turn creates a much more efficient query plan:
```
Limit (cost=0.43..1.44 rows=1 width=891) (actual time=0.033..0.034 rows=1 loops=1)
-> Index Scan using index_posts_on_topic_id_and_post_number on posts (cost=0.43..678.82 rows=671 width=891) (actua
l time=0.033..0.033 rows=1 loops=1)
Index Cond: ((topic_id = 160918) AND (post_number = 1))
Planning time: 0.167 ms
Execution time: 0.072 ms
(5 rows)
```
This query plan uses the correct index, `Index Scan using index_posts_on_topic_id_and_post_number on posts`. Note that this is only a problem on forums with a larger amount of posts; tiny forums would not notice the difference. On large forums a query for a topic that takes 1s without a bookmark can take 8-30 seconds, and even end up with 502 errors from nginx.
* 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
* FEATURE: allow category group moderators to edit posts
If the `enable_category_group_moderation` SiteSetting is enabled, posts should be editable by those belonging to the appropraite groups.
Previously if a onebox timed out we would not present the users in the log
with any information regarding the onebox. This makes it very difficult to
debug.
This adds url/topic/user in the debugging output.
`max-width: 50%; max-height: 400px;` is a good fallback, however, if width and height are given and are smaller than fallback - we should persist that smaller size.
Our Email::Sender class accepts an optional user argument, which is used to create a PostReplyKey record when present. This record is used to sub out the %{reply_key} placeholder in the Reply-To mail header, so if we do not pass in the user we get a broken Reply-To header.
This is especially problematic in the IMAP group SMTP situation, because these emails go to customers that we are replying to, and when they reply to us the email bounces! This fixes the issue by passing user to the Email::Sender when sending a group_smtp email but there is still more to do in another PR.
This Email::Sender optional user is a bit of a footgun IMO, especially because most of the time we use it there is a user we can source. I would like to do another PR for this after this one to make the parameter not optional, so we don't end up with these reply issues down the line again.
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.
This consolidates logic used to match routes in ApiKey, UserApiKey and DefaultCurrentUserProvider. This reduces duplicated logic, and will allow UserApiKeysScope to easily re-use the parameter matching logic from ApiKeyScope
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.
It pauses Sidekiq, clears Redis (namespaced to the current site), clears Sidekiq jobs for the current site, restores the database and unpauses Sidekiq. Previously it stayed paused until the end of the restore.
Redis is cleared because we don't want any old data lying around (e.g. old Sidekiq jobs). Most data in Redis is prefixed with the name of the multisite, but Sidekiq jobs in a multisite are all stored in the same keys. So, deleting those jobs requires a little bit more logic.
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.
Limit git log output to the first line of the commit message
when generating the list of commits in a release. Some commit messages
are including the names of all commits that were squashed, resulting
in duplicate and confusing lines in the release notes.
discourse-perspective-api was not successfully running tests via the
qunit:test rake task due to inconsistent naming between core and the
repo. As a result we no longer need the mapping in the plugin rake task, too.
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.
Creates a BabelHelper builder using a default list of plugins, to ensure the transpiled code is always using the same plugins instead of differents plugins in different cases.
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

Previously, any errors in those files would e.g. blow up the update process in docker_manager.
Now it prints out an error and proceeds as if there was no compatibility file.
Includes:
* DEV: Extract setup_git_repo
* DEV: Use `Dir.mktmpdir`
* DEV: Default to `main` branch (The latest versions of git already do this, so to avoid problems do this by default)
* FIX: second factor cannot be enabled if SSO is enabled
If `enable_sso` setting is enabled then admin should not be able to
enable `enforce_second_factor` setting as that will lock users out.

DEV: Replace instances of Discourse.base_uri with Discourse.base_path
This is clearer because the base_uri is actually just a path prefix. This continues the work started in 555f467.
We can't use erb in Ember CLI (since it does not have Ruby) so this has
been ported to use our `javascript:update_constants` rake test instead.
Note we don't have to run this every time a notification type as it's
only used by fixtures to fill in some specific types we test against.
See https://meta.discourse.org/t/email-address-change-confirmation-email-not-sent-but-every-other-notification-emails-are/165358
In short: with disable emails set to non-staff, email address change confirmation emails (those sent to the new address) are not sent for staff or admin members.
This was happening because we were looking up the staff user with the to_address of the email, but the to address was the new email address because we are sending a confirm email change email, and thus the user could not be found. We didn't need to do this anyway because we are passing the user into the Email::Sender class anyway.
* PERF: avoid lookbehinds when indexing search
Previously we used a `EmailCook.url_regexp` this regex used lookbehinds
Unfortunately certain strings could lead to pathological behavior causing
CPU to skyrocket and regex replace to take a very very long time.
EmailCook still needs a fix, but it is less urgent cause it already splits
to single lines. That said we will correct that as well in a seperate PR.
New implementation is far more naive and relies on the extra spaces search
indexer inserts.
When that site setting is enabled, the category counts (new/unread)
include the subcategory definition topics, but the topics aren't included
in the list. This fixes that discrepancy.
This plugin is only useful for developers, however, making it core allows us to centralize any component modification in one commit.
This integration also adds a new site_setting: `styleguide_admin_only` which allows to enable a styleguide on a live site while restricting visibility to admins only.
By default, styleguide is disabled.
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.
When enable_personal_messages was disabled, moderators could not see
the private messages for the "moderators" group. The link was displayed
on the client side, but the checks on the server side did not allow it.
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.
UploadRecovery only worked on missing Upload records. Now it also works with existing ones that have an invalid_etag status.
The specs (first that test the S3 path) are a bit of stub-a-palooza, but that's how much this class interacts with the the outside world. 🤷♂️
Upload.secure_media_url? raised an exceptions when the URL was invalid,
which was a issue in some situations where secure media URLs must be
removed.
For example, sending digests used PrettyText.strip_secure_media,
which used Upload.secure_media_url? to replace secure media with
placeholders. If the URL was invalid, then an exception would be raised
and left unhandled.
Now instead in UrlHelper.rails_route_from_url we return nil if there is something wrong with the URL.

The download link on the lightbox for images was not downloading the image if the upload was marked secure, because the code in the upload controller route was not respecting the dl=1 param for force download.
This PR fixes this so the download link works for secure images as well as regular ligthboxed images.
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.
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
Since 9e4ed03, moderators can view groups with visibility level set to "Group owners, members and moderators".
This fixes an issue where moderators can see the group in /g but then get a 404 when clicking on individual groups.
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.
With secure media and the UploadSecurity class, we need a nice way for plugins to register custom upload types that should be considered public and never secure.
This is intended for use by plugins which are building their own topic lists, and want to include PMs alongside regular topics (e.g. discourse-assign). It does not get used directly in core.
* DEV - versions of JS files written to a JS file to be included by load-script and appended as params to URLs

Editing a post didn't update the `post_uploads` right away. Instead it relied on the `CookedPostProcessor`. This can lead to an inconsistent state if uploads are added or removed during an edit and, for some reason, the `ProcessPost` job doesn't run (successfully). This inconsistency leads to missing uploads, because the newly added uploads appear to be unused and will be deleted by the `CleanUpUploads` job. In addition to that, uploads, which got removed during the edit, appear to be still in use and won't be deleted by the background job.
This commit ensures that the `post_uploads` are updated during the edit without relying on a background job.
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.
After restoring a backup it takes up to 48 hours for uploads stored on S3 to appear in the S3 inventory. This change prevents alerts about missing uploads by preventing the EnsureS3UploadsExistence job from running in the first 48 hours after a restore. During the restore it deletes the count of missing uploads from the PluginStore, so that an alert isn't triggered by an old number.
We must guarantee that "rel=noopener" was set if "target=_blank" is present, which is not always the case for trusted users. Also, if the link contains the "nofollow" attribute, it has to have the "ugc" attribute as well.
In c6ceda8c, a bug was introduced where an admin searching for his own
private messages will actually end up searching through all private
messages on the site.
Follow-up to c6ceda8c4e
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.
- Lets child components extend color definitions
- Includes default theme color definitions
- Fails gracefully on color stylesheet SCSS errors
- Includes theme variables when extending colors
This PR ensures that new bookmarks cannot be created for deleted posts and topics, and also makes sure that if a bookmark was created and then the topic deleted that the show topic page does not error from trying to retrieve the bookmark reminder at.
Adding these classes to the stylesheet link elements in order to toggle dark/light schemes via this theme-component. Eventually this theme-component could possible be merged into core.
DEV: add plugin hooks for silence message parameters
Allows plugins to add, and update extra silence message params for custom
i18n vars
Allows plugins to override system messages via `message_title` and
`message_raw` parameters. We can later expose these params where necessary via event
hooks. Expose the parameter for the on user_silenced trigger.
* DEV: Switch our fast_xor gem for xorcist
We use the `xor` function as part of password hashing and we want to use
a faster version than the native ruby xor'ing feature so we use a gem
for this.
fast_xor has been abandoned, and xorcist fixed our initial holdup for
switching in https://github.com/fny/xorcist/issues/4
xorcist also has jruby support so we can remove our jruby fallback
logic.
