Previously we would unconditionally keep all images downloaded via pull_hotlinked_images, even if they are later removed from the post. This commit removes that logic, and relies on the existing link_post_uploads process to pick up the downloaded images in `cooked`. Specs are added to ensure this is working correctly for regular hotlinked images, and for oneboxes.
This commit should cause no functional change
- Split into functions to avoid deep nesting
- Register custom field type, and remove manual json parse/serialize
- Recover from deleted upload records
Also adds a test to ensure pull_hotlinked_images redownloads secure images only once
* FEATURE: notify admins about old credentials
Security and API keys should be renewed periodically.
This additional notification should help admins keep their Discourse safe and secure.
* DEV: new S3 backup layout
Currently, with $S3_BACKUP_BUCKET of "bucket/backups", multisite backups
end up in "bucket/backups/backups/dbname/" and single-site will be in
"bucket/backups/".
Both _should_ be in "bucket/backups/dbname/"
- remove MULTISITE_PREFIX,
- always include dbname,
- method to move to the new prefix
- job to call the method
* SPEC: add tests for `VacateLegacyPrefixBackups` onceoff job.

When running jobs in tests, we use `Jobs.run_immediately!`. This means that jobs are run synchronously when they are enqueued. Jobs sometimes enqueue other jobs, which are also executed synchronously. This means that the outermost job will block until the inner jobs have finished executing. In some cases (e.g. process_post with hotlinked images) this can lead to a deadlock.
This commit changes the behavior slightly. Now we will never run jobs inside other jobs. Instead, we will queue them up and run them sequentially in the order they were enqueued. As a whole, they are still executed synchronously. Consider the example
```ruby
class Jobs::InnerJob < Jobs::Base
def execute(args)
puts "Running inner job"
end
end
class Jobs::OuterJob < Jobs::Base
def execute(args)
puts "Starting outer job"
Jobs.enqueue(:inner_job)
puts "Finished outer job"
end
end
Jobs.enqueue(:outer_job)
puts "All jobs complete"
```
The old behavior would result in:
```
Starting outer job
Running inner job
Finished outer job
All jobs complete
```
The new behavior will result in:
```
Starting outer job
Finished outer job
Running inner job
All jobs complete
```
It might happen that some User records have no associated primary emails.
In which case we don't ever want to send them a digest.
Also added a new "user_email_no_email" skipped email log to ensure these cases
are properly handled and surfaced.

This reverts commit 6f9177e2ed.
We decided on a completely different approach to the problem.
Instead we will let blocked emails be treated as canonical.
The main thrust of this PR is to take all the conditional checks based on the `enable_bookmarks_with_reminders` away and only keep the code from the `true` path, making bookmarks with reminders the core bookmarks feature. There is also a migration to create `Bookmark` records out of `PostAction` bookmarks for a site.
### Summary
* Remove logic based on whether enable_bookmarks_with_reminders is true. This site setting is now obsolete, the old bookmark functionality is being removed. Retain the setting and set the value to `true` in a migration.
* Use the code from the rake task to create a database migration that creates bookmarks from post actions.
* Change the bookmark report to read from the new table.
* Get rid of old endpoints for bookmarks
* Link to the new bookmarks list from the user summary page
Within 24 hours of signing up, new users were losing their
default trust level of 3. With this fix, demotions from
trust level 3 won't happen when the "default trust level"
setting is 3 or 4.
The new `enforce_canonical_emails` site setting ensures that emails in the
canonical form are unique.
This mean that if `s.a.m+1@gmail.com` is registered `sam@gmail.com` will
not be allowed.
The commit contains a blanket "tag strip" (stripping everything after +)
it also contains special handling of a "dot strip" for googlemail and gmail.
The setting only impacts new registrations after `enforce_canonical_emails`
The setting is default false so it will not impact any existing installs.
If the “secure media” site setting is enabled then ALL files uploaded to Discourse (images, video, audio, pdf, txt, zip etc. etc.) will follow the secure media rules. The “prevent anons from downloading files” setting will no longer have any bearing on upload security. Basically, the feature will more appropriately be called “secure uploads” instead of “secure media”.
This is being done because there are communities out there that would like all attachments and media to be secure based on category rules but still allow anonymous users to download attachments in public places, which is not possible in the current arrangement.
* This PR implements the scheduling and notification system for bookmark reminders. Every 5 minutes a schedule runs to check any reminders that need to be sent before now, limited to **300** reminders at a time. Any leftover reminders will be sent in the next run. This is to avoid having to deal with fickle sidekiq and reminders in the far-flung future, which would necessitate having a background job anyway to clean up any missing `enqueue_at` reminders.
* If a reminder is sent its `reminder_at` time is cleared and the `reminder_last_sent_at` time is filled in. Notifications are only user-level notifications for now.
* All JavaScript and frontend code related to displaying the bookmark reminder notification is contained here. The reminder functionality is now re-enabled in the bookmark modal as well.
* This PR also implements the "Remind me next time I am at my desktop" bookmark reminder functionality. When the user is on a mobile device they are able to select this option. When they choose this option we set a key in Redis saying they have a pending at desktop reminder. The next time they change devices we check if the new device is desktop, and if it is we send reminders using a DistributedMutex. There is also a job to ensure consistency of these reminders in Redis (in case Redis drops the ball) and the at desktop reminders expire after 20 days.
* Also in this PR is a fix to delete all Bookmarks for a user via `UserDestroyer`
* DEV: Reserve webhook event types to be used in plugins
Based on feedback on the following PR's:
https://github.com/discourse/discourse-solved/pull/85https://github.com/discourse/discourse-assign/pull/61
This commit reserves ID's to be used for webhook event types to ensure
that some other webhook or plugin doesn't end up using the same ID.
* Fix broken test
I don't think this test has to test ALL event types to verify that this
feature is working. Now that we added some event types that plugins are
using this test was failing for missing fabricators that exist in the
respective plugins.
* remove loop and just test first record
* Add uploads:sync_s3_acls rake task to ensure the ACLs in S3 are the correct (public-read or private) setting based on upload security
* Improved uploads:disable_secure_media to be more efficient and provide better messages to the user.
* Rename uploads:ensure_correct_acl task to uploads:secure_upload_analyse_and_update as it does more than check the ACL
* Many improvements to uploads:secure_upload_analyse_and_update
* Make sure that upload.access_control_post is unscoped so deleted posts are still fetched, because they still affect the security of the upload.
* Add escape hatch for capture_stdout in the form of RAILS_ENABLE_TEST_STDOUT. If provided the capture_stdout code will be ignored, so you can see the output if you need.
Basically, say you had already downloaded a certain image from a certain URL
using pull_hotlinked_images and the onebox. The upload would be stored
by its sha as an upload record. Whenever you linked to the same URL again
in a post (e.g. in our case an og:image on review.discourse) we would
would reuse the original upload record because of the sha1.
However when you turned on secure media this could cause problems as
the first post that uses that upload after secure media is enabled
will set the access control post for the upload to the new post.
Then if the post is deleted every single onebox/link to that same image
URL will fail forever with 403 as the secure-media-uploads URL fails
if the access control post has been deleted.
To fix this when cooking posts and pulling hotlinked images, we only
allow using an original upload by URL if its access control post
matches the current post, and if the original_sha1 is filled in,
meaning it was uploaded AFTER secure media was enabled. otherwise
we just redownload the media again to be safe, as the URL will always
be new then.
Regression was created here:
https://github.com/discourse/discourse/pull/8750
When tag or category is added and the user is watching that category/tag
we changed notification type to `edited` instead of `new post`.
However, the logic here should be a little bit more sophisticated.
If the user has already seen the post, notification should be `edited`.
However, when user hasn't yet seen post, notification should be "new
reply". The case for that is when for example topic is under private
category and set for publishing later. In that case, we modify an
existing topic, however, for a user, it is like a new post.
Discussion on meta:
https://meta.discourse.org/t/publication-of-timed-topics-dont-trigger-new-topic-notifications/139335/13
Previously the badge was granted one month after the last time the badge was granted. The exact date shifted by one day each month. The new logic tries to grant the badge always at the beginning of a new month by looking at new users of the previous month. The "granted at" date is set to the end of the previous month.
When pull_hotlinked_images tried to run on posts with secure media (which had already been downloaded from external sources) we were getting a 404 when trying to download the image because the secure endpoint doesn't allow anon downloads.
Also, we were getting into an infinite loop of pull_hotlinked_images because the job didn't consider the secure media URLs as "downloaded" already so it kept trying to download them over and over.
In this PR I have also refactored secure-media-upload URL checks and mutations into single source of truth in Upload, adding a SECURE_MEDIA_ROUTE constant to check URLs against too.
There is a feature, that when tag or category is added to the topic,
customers who are watching that category or tag are notified.
The problem is that it is using default notification type "new post"
It would be better to use "new post" only when there really is a new
post and "edited" when categories or tags were modified.
### General Changes and Duplication
* We now consider a post `with_secure_media?` if it is in a read-restricted category.
* When uploading we now set an upload's secure status straight away.
* When uploading if `SiteSetting.secure_media` is enabled, we do not check to see if the upload already exists using the `sha1` digest of the upload. The `sha1` column of the upload is filled with a `SecureRandom.hex(20)` value which is the same length as `Upload::SHA1_LENGTH`. The `original_sha1` column is filled with the _real_ sha1 digest of the file.
* Whether an upload `should_be_secure?` is now determined by whether the `access_control_post` is `with_secure_media?` (if there is no access control post then we leave the secure status as is).
* When serializing the upload, we now cook the URL if the upload is secure. This is so it shows up correctly in the composer preview, because we set secure status on upload.
### Viewing Secure Media
* The secure-media-upload URL will take the post that the upload is attached to into account via `Guardian.can_see?` for access permissions
* If there is no `access_control_post` then we just deliver the media. This should be a rare occurrance and shouldn't cause issues as the `access_control_post` is set when `link_post_uploads` is called via `CookedPostProcessor`
### Removed
We no longer do any of these because we do not reuse uploads by sha1 if secure media is enabled.
* We no longer have a way to prevent cross-posting of a secure upload from a private context to a public context.
* We no longer have to set `secure: false` for uploads when uploading for a theme component.
* UI: Mass grant a badge from the admin ui
* Send the uploaded CSV and badge ID to the backend
* Read the CSV and grant badge in batches
* UX: Communicate the result to the user
* Don't award if badge is disabled
* Create a 'send_notification' method to remove duplicated code, slightly shrink badge image. Replace router transition with href.
* Dynamically discover current route
The secure media functionality relied on `SiteSetting.enable_s3_uploads?` which, as we found in dev, did not take into account global S3 settings via `GlobalSetting.use_s3?`. We now use `SiteSetting.Upload.enable_s3_uploads` instead to be more consistent.
Also, we now validate `enable_s3_uploads` changes, because if `GlobalSetting.use_s3?` is true users should NOT be enabling S3 uploads manually.
I made a regression here 17366d3bcc (diff-ddeebb36d131f89ca91be9d04c2baefaR10)
When the tag is added, people watching specific tag are notified but also people watching specific category.
Therefore, `notify_post_users` should accept options who should be notified.
So when `category` is added to the topic, users watching topic and users watching category are notified.
When `tag` is added to the topic, users watching topic and users watching tag are notified
Finally, when a new post is created, everybody is notified, topic watchers, category watchers, tag watchers.
* Fix user title logic when badge name customized
* Fix an issue where a user's title was not considered a badge granted title when the user used a badge for their title and the badge name was customized. this affected the effectiveness of revoke_ungranted_titles! which only operates on badge_granted_titles.
* When a user's title is set now it is considered a badge_granted_title if the badge name OR the badge custom name from TranslationOverride is the same as the title
* When a user's badge is revoked we now also revoke their title if the user's title matches the badge name OR the badge custom name from TranslationOverride
* Add a user history log when the title is revoked to remove confusion about why titles are revoked
* Add granted_title_badge_id to user_profile, now when we set badge_granted_title on a user profile when updating a user's title based on a badge, we also remember which badge matched the title
* When badge name (or custom text) changes update titles of users in a background job
* When the name of a badge changes, or in the case of system badges when their custom translation text changes, then we need to update the title of all corresponding users who have a badge_granted_title and matching granted_title_badge_id. In the case of system badges we need to first get the proper badge ID based on the translation key e.g. badges.regular.name
* Add migration to backfill all granted_title_badge_ids for both normal badge name titles and titles using custom badge text.
Issue was mentioned in this [meta topic](https://meta.discourse.org/t/send-a-notification-to-watching-users-when-adding-tag/125314)
It is working well when category is changed because NotifyCategoryChange job already got that code:
```
if post&.topic&.visible?
post_alerter = PostAlerter.new
post_alerter.notify_post_users(post, User.where(id: args[:notified_user_ids]))
post_alerter.notify_first_post_watchers(post, post_alerter.category_watchers(post.topic))
end
```
For NotifyTagChange job notify post users were missing so it worked only when your notification was set to `watching first post`
Previously every hour we would run a full scan of the entire DB searching
for expired uploads that need to be moved to the tombstone folder.
This commit amends it so we only run the job 2 times per clean_orpha_uploads_grace_period_hours
There is a upper bound of 7 days so even if the grace period is set really
high it will still run at least once a week.
By default we have a 48 grace period so this amends it to run this cleanup
daily instead of hourly. This eliminates 23 times we run this ultra expensive
query.
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
Previously, calculating thresholds for reviewables was done based on the
50th and 85th percentile across all reviewables. However, many forum
owners provided feedback that these thresholds were too easy to hit, in
particular when it came to auto hiding content.
The calculation has been adjusted to base the priorities on reviewables
that have a minimum of 2 scores (flags). This should push the amount of
flags required to hide something higher then before.
On forums with very few flags you don't want to calculate averages
because they won't be very useful. Stick with the defaults until we hit
15 reviewables at least.
This reverts commit e805d44965.

DEV: deprecate `invite.via_email` in favor of `invite.emailed_status`
This commit adds a new column `emailed_status` in `invites` table for
tracking email sending status.
0 - not required
1 - pending
2 - bulk pending
3 - sending
4 - sent
For normal email invites, invite record is created with emailed_status
set to 'pending'.
When bulk invites are sent invite record is created with emailed_status
set to 'bulk pending'.
For invites that generates link, invite record is created with
emailed_status set to 'not required'.
When invite email is in queue emailed_status is updated to 'sending'
Once the email is sent via `InviteEmail` job the invite emailed_status
is updated to 'sent'.
This does two things
1. Our "index grace period" has been wound down to 1 day, there is no point
keeping a bloated index for a week, usually when people delete stuff they
mean for it to be removed
2. We were never dropping deleted posts from the index, only posts from
deleted topics
These changes speed up search a tiny bit and reduce background work.
The `AutoQueueHandler` will ignore really old flags. In that case, don't
notify the user that the moderator is looking into it. They probably
never saw it because it didn't meet the reviewable minimum priority.
We found score hard to understand. It is still there behind the scenes
for sorting purposes, but it is no longer shown.
You can now filter by minimum priority (low, med, high) instead of
score.
* Introduced fab!, a helper that creates database state for a group
It's almost identical to let_it_be, except:
1. It creates a new object for each test by default,
2. You can disable it using PREFABRICATION=0
This removes all uses of both `send` and `public_send` from consumers of
SiteSetting and instead introduces a `get` helper for dynamic lookup
This leads to much cleaner and safer code long term as we are always explicit
to test that a site setting is really there before sending an arbitrary
string to the class
It also removes a couple of risky stubs from the auth provider test
`Upload#url` is more likely and can change from time to time. When it
does changes, we don't want to have to look through multiple tables to
ensure that the URLs are all up to date. Instead, we simply associate
uploads properly to `UserProfile` so that it does not have to replicate
the URLs in the table.
This change both speeds up specs (less strings to allocate) and helps catch
cases where methods in Discourse are mutating inputs.
Overall we will be migrating everything to use #frozen_string_literal: true
it will take a while, but this is the first and safest move in this direction
If you turn it on now, default all users to approved since they were
previously. Also support approving a user that doesn't have a reviewable
record (it will be created first.)
This also includes a refactor to move class method calls to
`DiscourseEvent` into an initializer. Otherwise the load order of
classes makes a difference in the test environment and some settings
might be triggered and others not, randomly.
Theme developers can include any number of scss files within the /scss/ directory of a theme. These can then be imported from the main common/desktop/mobile scss.
- Plugin developers using OpenID2.0 should migrate to OAuth2 or OIDC. OpenID2.0 APIs will be removed in v2.4.0
- For sites requiring Yahoo login, it can be implemented using the OpenID Connect plugin: https://meta.discourse.org/t/103632
For more information, see https://meta.discourse.org/t/113249
"Rejecting" a user in the queue is equivalent to deleting them, which
would then making it impossible to review rejected users. Now we store
information about the user in the payload so if they are deleted things
still display in the Rejected view.
Secondly, if a user is destroyed outside of the review queue, it will
now automatically "Reject" that queue item.
If the post ids keep loading, we might end up in a situations where
we're always loading the same post ids over and over again without
indexing anything new.
Follow up to daeda80ada.
Includes support for flags, reviewable users and queued posts, with REST API
backwards compatibility.

Previously we would bypass touching `Topic.updated_at` for whispers and post
recovery / deletions.
This meant that certain types of caching can not be done where we rely on
this information for cache accuracy.
For example if we know we have zero unread topics as of yesterday and whisper
is made I need to bump this date so the cache remains accurate
This is only half of a larger change but provides the groundwork.
Confirmed none of our serializers leak out Topic.updated_at so this is safe
spot for this info
At the moment edits still do not change this but it is not relevant for the
unread cache.
This commit also cleans up some specs to use the new `eq_time` matcher for
millisecond fidelity comparison of times
Previously `freeze_time` would fudge this which is not that clean.
- The test_email job is removed, because it was always being run synchronously (not in sidekiq)
- 34b29f62 added a bypass for critical emails, to match the spec. This removes the bypass, and removes the spec.
- This adapts the specs for 72ffabf6, so that they check for emails being sent
- This reimplements c2797921, allowing test emails to be sent even when emails are disabled
* Remove use of 0 in favor of `TrustLevel.levels[:newuser]`.
* Consolidate two tests into a single one.
* Test that disabling the feature works.
* Avoid loading full ActiveRecord object in test when we only need to
know the existence of the record.
Migrates email user options to a new data structure, where `email_always`, `email_direct` and `email_private_messages` are replace by
* `email_messages_level`, with options: `always`, `only_when_away` and `never` (defaults to `always`)
* `email_level`, with options: `always`, `only_when_away` and `never` (defaults to `only_when_away`)
* FEATURE: Add `IgnoredUsersSummary` daily job
## Why?
This is part of the [Ability to ignore a user feature](https://meta.discourse.org/t/ability-to-ignore-a-user/110254/8).
We want to:
1. Send an automatic group PM that goes out to moderators
2. When {x} users have Ignored the same user, threshold defined by a site setting, default of 5
3. Only send this message every X days which is defined by another site setting
It is not a setting, and only relevant in specs. The new API is:
```
Jobs.run_later! # jobs will be thrown on the queue
Jobs.run_immediately! # jobs will run right away, avoid the queue
```
We can only be sure that an email is sent when we get a mailer in
`ActionMailer::Deliveries`. A couple of tests were actually incorrect
because it didn't flow through our email sender where there are more
conditions in determining whether an email is sent or not.
Previously if you wanted to have jobs execute in test mode, you'd have
to do `SiteSetting.queue_jobs = false`, because the opposite of queue
is to execute.
I found this very confusing, so I created a test helper called
`run_jobs_synchronously!` which is much more clear about what it does.
There was a situation where if:
* There were new flags to review that met the visibility threshold
AND
* There were old flags that *didn't* meet the threshold
THEN
a pending flags notification would be sent out. This fixes that case.
Staff should not be notified of flags if they do not meet the threshold
and are old.
This commit introduces an ultra low priority queue for post rebakes. This
way rebakes can never interfere with regular sidekiq processing for cases
where we perform a large scale rebake.
Additionally it allows Post.rebake_old to be run with rate_limiter: false
to avoid triggering the limiter when rebaking. This is handy for cases
where you want to just force the full rebake and not wait for it to trickle
Previously we depended on non Sidekiq specific mocking which is not the
official way of testing Sidekiq, this made these tests very fragile
New testing is more robust and complete
This allows us to run regular rebakes without starving the normal queue.
It additionally adds the ability to specify queue with `Jobs.enqueue` so
we can specifically queue a job with lower priority using the `queue` arg.
* Add missing icons to set
* Revert FA5 revert
This reverts commit 42572ff
* use new SVG syntax in locales
* Noscript page changes (remove login button, center "powered by" footer text)
* Cast wider net for SVG icons in settings
- include any _icon setting for SVG registry (offers better support for plugin settings)
- let themes store multiple pipe-delimited icons in a setting
- also replaces broken onebox image icon with SVG reference in cooked post processor
* interpolate icons in locales
* Fix composer whisper icon alignment
* Add support for stacked icons
* SECURITY: enforce hostname to match discourse hostname
This ensures that the hostname rails uses for various helpers always matches
the Discourse hostname
* load SVG sprite with pre-initializers
* FIX: enable caching on SVG sprites
* PERF: use JSONP for SVG sprites so they are served from CDN
This avoids needing to deal with CORS for loading of the SVG
Note, added the svg- prefix to the filename so we can quickly tell in
dev tools what the file is
* Add missing SVG sprite JSONP script to CSP
* Upgrade to FA 5.5.0
* Add support for all FA4.7 icons
- adds complete frontend and backend for renamed FA4.7 icons
- improves performance of SvgSprite.bundle and SvgSprite.all_icons
* Fix group avatar flair preview
- adds an endpoint at /svg-sprites/search/:keyword
- adds frontend ajax call that pulls icon in avatar flair preview even when it is not in subset
* Remove FA 4.7 font files
* Doing it in a post migration was a bad idea
because the migration will fail if the site
is down while trying to download uploads
which points to the instance. This mainly
affects self-hosters using `discourse_docker`
where `./launcher rebuild` will take the
existing container down.
Last week we added support for dual stack urls but did not remap the
the old records in the uploads and optimized images table
This caused a few minor edge cases worst was that if you rebaked old
images S3 CDN was not repopulated.
If sidekiq is paused or Discourse is in readonly continue to queue
heartbeats
If we do not do that then a master process can end up reaping sidekiq
workers and causing various badness
This also impacts restore which can do weird stuff TM in cases like this
Introduces a hidden setting (default is 0.1) that erodes bounce score
every time we send an email. This means that erratic failures are less
painful cause system auto corrects
