77137c5d29 FIX: Single line emojis has emoji metadata indexed twice.
This commit fixes a bug where we our `HTMLScrubber` was only searching
for emoji img tags which contains only the "emoji" class. However, our emoji image tags
may contain more than just the "emoji" class like "only-emoji" when an
emoji exists by itself on a single line.

FEATURE: Before consolidation callbacks. (#15428)
You can add callbacks that get called before updating an already consolidated notification or creating a consolidated one.

Instances of this rule can add callbacks to access the old notifications about to be destroyed or the consolidated one and add additional data inside the data hash versus having to execute extra queries when adding this logic inside the `set_mutations` block.

DEV: Create post actions without creating a notification and store custom data. (#15397)
I plan to use this in an upcoming discourse-reactions PR, where I want to like a post without notifying the user, so I can instead create a reaction notification.

Additionally, we decouple the a11y attributes from the icon itself, which will let us extend the widget's icon without losing them.

REFACTOR: Use a consolidation rule for collapsing likes. (#15393)
This PR moves the behavior from the PostAlerter. We delete an existing liked notification and set the `username2` attribute to the previous `display_username`. We repeat this process unless the last one is old enough or it's not in the most recent ones.

FEATURE: A notification consolidation plan for keeping the latest one. (#15249)
We previously used ConsolidateNotifications with a threshold of 1 to re-use an existing notification and bump it to the top instead of creating a new one. It produces some jumpiness in the user notification list, and it relies on updating the `created_at` attribute, which is a bit hacky.

As a better alternative, we're introducing a new plan that deletes all the previous versions of the notification, then creates a new one.

FEATURE: Experimental support for group membership via google auth (#14835)
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.

REFACTOR: Improve support for consolidating notifications. (#14904)
* REFACTOR: Improve support for consolidating notifications.

Before this commit, we didn't have a single way of consolidating notifications. For notifications like group summaries, we manually removed old ones before creating a new one. On the other hand, we used an after_create callback for likes and group membership requests, which caused unnecessary work, as we need to delete the record we created to replace it with a consolidated one.

We now have all the consolidation rules centralized in a single place: the consolidation planner class. Other parts of the app looking to create a consolidable notification can do so by calling Notification#consolidate_or_save!, instead of the default Notification#create! method.

Finally, we added two more rules: one for re-using existing group summaries and another for deleting duplicated dashboard problems PMs notifications when the user is tracking the moderator's inbox. Setting the threshold to one forces the planner to apply this rule every time.

I plan to add plugin support for adding custom rules in another PR to keep this one relatively small.

* DEV: Introduces a plugin API for consolidating notifications.

This commit removes the `Notification#filter_by_consolidation_data` scope since plugins could have to define their criteria. The Plan class now receives two blocks, one to query for an already consolidated notification, which we'll try to update, and another to query for existing ones to consolidate.

It also receives a consolidation window, which accepts an ActiveSupport::Duration object, and filter notifications created since that value.

DEV: Hash tokens stored from email_tokens (#14493)
This commit adds token_hash and scopes columns to email_tokens table.
token_hash is a replacement for the token column to avoid storing email
tokens in plaintext as it can pose a security risk. The new scope column
ensures that email tokens cannot be used to perform a different action
than the one intended.

To sum up, this commit:

* Adds token_hash and scope to email_tokens

* Reuses code that schedules critical_user_email

* Refactors EmailToken.confirm and EmailToken.atomic_confirm methods

* Periodically cleans old, unconfirmed or expired email tokens

messages to MessageBus from both PostAlerter and User#publish_notification_state.
This can cause memory issues on large sites with many users. This commit
stems the bleeding by only sending these alert messages if the user
in question has been seen in the last 30 days, which eliminates a large
chunk of users on some sites.

When 31035010af

site setting was true, but the topic had no allowed groups / no
incoming email record, which caused errors for topics even with
nothing to do with group SMTP.

FIX: Use correct group out of multiple for SMTP sender (#14957)
When there are multiple groups on a topic, we were selecting
the first from the topic allowed groups to act as the sender
email address when sending group SMTP replies via PostAlerter.
However, this was not ordered, and since there is no created_at
column on TopicAllowedGroup we cannot order this nicely, which
caused just a random group to be used (based on whatever postgres
decided it felt like that morning).

This commit changes the group used for SMTP sending to be the
group using the email_username of the to address of the first
incoming email for the topic, if there are more than one allowed
groups on the topic. Otherwise it just uses the only SMTP enabled
group.

FEATURE: Direct S3 multipart uploads for backups (#14736)
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.

FIX: Ensure CORS rules exist for S3 using rake task (#14802)
This commit introduces a new s3:ensure_cors_rules rake task
that is run as a prerequisite to s3:upload_assets. This rake
task calls out to the S3CorsRulesets class to ensure that
the 3 relevant sets of CORS rules are applied, depending on
site settings:

* assets
* direct S3 backups
* direct S3 uploads

This works for both Global S3 settings and Database S3 settings
(the latter set directly via SiteSetting).

As it is, only one rule can be applied, which is generally
the assets rule as it is called first. This commit changes
the ensure_cors! method to be able to apply new rules as
well as the existing ones.

This commit also slightly changes the existing rules to cover
direct S3 uploads via uppy, especially multipart, which requires
some more headers.

FEATURE: Change all core to use uppy-image-uploader (#14428)
Instead of using image-uploader, which relies on the old
UploadMixin, we can now use the uppy-image-uploader which
uses the new UppyUploadMixin which is stable enough and
supports both regular XHR uploads and direct S3 uploads,
controlled by a site setting (default to XHR).

At some point it may make sense to rename uppy-image-uploader
back to image-uploader, once we have gone through plugins
etc. and given a bit of deprecation time period.

This commit also fixes `for_private_message`, `for_site_setting`,
and `pasted` flags not being sent via uppy uploads onto the
UploadCreator, both via regular XHR uploads and also through
external/multipart uploads.

The uploaders changed are:

* site setting images
* badge images
* category logo
* category background
* group flair
* profile background
* profile card background

FEATURE: Uppy direct S3 multipart uploads in composer (#14051)
This pull request introduces the endpoints required, and the JavaScript functionality in the `ComposerUppyUpload` mixin, for direct S3 multipart uploads. There are four new endpoints in the uploads controller:

* `create-multipart.json` - Creates the multipart upload in S3 along with an `ExternalUploadStub` record, storing information about the file in the same way as `generate-presigned-put.json` does for regular direct S3 uploads
* `batch-presign-multipart-parts.json` - Takes a list of part numbers and the unique identifier for an `ExternalUploadStub` record, and generates the presigned URLs for those parts if the multipart upload still exists and if the user has permission to access that upload
* `complete-multipart.json` - Completes the multipart upload in S3. Needs the full list of part numbers and their associated ETags which are returned when the part is uploaded to the presigned URL above. Only works if the user has permission to access the associated `ExternalUploadStub` record and the multipart upload still exists.

  After we confirm the upload is complete in S3, we go through the regular `UploadCreator` flow, the same as `complete-external-upload.json`, and promote the temporary upload S3 into a full `Upload` record, moving it to its final destination.
* `abort-multipart.json` - Aborts the multipart upload on S3 and destroys the `ExternalUploadStub` record if the user has permission to access that upload.

Also added are a few new columns to `ExternalUploadStub`:

* multipart - Whether or not this is a multipart upload
* external_upload_identifier - The "upload ID" for an S3 multipart upload
* filesize - The size of the file when the `create-multipart.json` or `generate-presigned-put.json` is called. This is used for validation.

When the user completes a direct S3 upload, either regular or multipart, we take the `filesize` that was captured when the `ExternalUploadStub` was first created and compare it with the final `Content-Length` size of the file where it is stored in S3. Then, if the two do not match, we throw an error, delete the file on S3, and ban the user from uploading files for N (default 5) minutes. This would only happen if the user uploads a different file than what they first specified, or in the case of multipart uploads uploaded larger chunks than needed. This is done to prevent abuse of S3 storage by bad actors.

Also included in this PR is an update to vendor/uppy.js. This has been built locally from the latest uppy source at d613b849a6. This must be done so that I can get my multipart upload changes into Discourse. When the Uppy team cuts a proper release, we can bump the package.json versions instead.

DEV: remove calls to guardian from GroupActionLogger (#13835)
We shouldn't be checking if a user is allowed to do an action in the logger. We should be checking it just before we perform the action. In fact, guardians in the logger can make things even worse in case of a security bug. Let's say we forgot to check user's permissions before performing some action, but we still have a call to the guardian in the logger. In this case, a user would perform the action anyway, and this action wouldn't even be logged!

I've checked all cases and I confirm that we're safe to delete this calls from the logger.

I've added two calls to guardians in admin/user_controller. We didn't have security bugs there, because regular users can't access admin/... routes at all. But it's good to have calls to guardian in these methods anyway, neighboring methods have them.
