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.
While merging two user accounts don't merge the source user's email address if the target user is not a human.

Long posts may have `cooked` fields that produce tsvectors longer than
the maximum size of 1MiB (1,048,576 bytes). This commit uses just the
first million characters of the scrubbed cooked text for indexing.
Reducing the size to exactly 1MB (1_048_576) is not sufficient because
sometimes the output tsvector may be longer than the input and this
gives us some breathing room.
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.
This adds a few different things to allow for direct S3 uploads using uppy. **These changes are still not the default.** There are hidden `enable_experimental_image_uploader` and `enable_direct_s3_uploads` settings that must be turned on for any of this code to be used, and even if they are turned on only the User Card Background for the user profile actually uses uppy-image-uploader.
A new `ExternalUploadStub` model and database table is introduced in this pull request. This is used to keep track of uploads that are uploaded to a temporary location in S3 with the direct to S3 code, and they are eventually deleted a) when the direct upload is completed and b) after a certain time period of not being used.
### Starting a direct S3 upload
When an S3 direct upload is initiated with uppy, we first request a presigned PUT URL from the new `generate-presigned-put` endpoint in `UploadsController`. This generates an S3 key in the `temp` folder inside the correct bucket path, along with any metadata from the clientside (e.g. the SHA1 checksum described below). This will also create an `ExternalUploadStub` and store the details of the temp object key and the file being uploaded.
Once the clientside has this URL, uppy will upload the file direct to S3 using the presigned URL. Once the upload is complete we go to the next stage.
### Completing a direct S3 upload
Once the upload to S3 is done we call the new `complete-external-upload` route with the unique identifier of the `ExternalUploadStub` created earlier. Only the user who made the stub can complete the external upload. One of two paths is followed via the `ExternalUploadManager`.
1. If the object in S3 is too large (currently 100mb defined by `ExternalUploadManager::DOWNLOAD_LIMIT`) we do not download and generate the SHA1 for that file. Instead we create the `Upload` record via `UploadCreator` and simply copy it to its final destination on S3 then delete the initial temp file. Several modifications to `UploadCreator` have been made to accommodate this.
2. If the object in S3 is small enough, we download it. When the temporary S3 file is downloaded, we compare the SHA1 checksum generated by the browser with the actual SHA1 checksum of the file generated by ruby. The browser SHA1 checksum is stored on the object in S3 with metadata, and is generated via the `UppyChecksum` plugin. Keep in mind that some browsers will not generate this due to compatibility or other issues.
We then follow the normal `UploadCreator` path with one exception. To cut down on having to re-upload the file again, if there are no changes (such as resizing etc) to the file in `UploadCreator` we follow the same copy + delete temp path that we do for files that are too large.
3. Finally we return the serialized upload record back to the client
There are several errors that could happen that are handled by `UploadsController` as well.
Also in this PR is some refactoring of `displayErrorForUpload` to handle both uppy and jquery file uploader errors.
Configuring staged users to watch categories and tags is a way to sign
them up to get many emails. These emails may be unwanted and get marked
as spam, hurting the site's email deliverability.
Users can opt-in to email notifications by logging on to their
account and configuring their own preferences.
If staff need to be able to configure these preferences on behalf of
staged users, the "allow changing staged user tracking" site setting
can be enabled. Default is to not allow it.

There was a bug with changing timestamps using the topic wrench button. Under some circumstances, a topic was disappearing from the top of the latest tab after changing timestamps. Steps to reproduce:
- Choose a topic on the latest tab (the topic should be created some time ago, but has recent posts)
- Change topic timestamps (for example, move them one day forward):
- Go back to the latest tab and see that topic has disappeared.
This PR fixes this. We were setting topic.bumped_at to the timestamp user specified on the modal. This is incorrect. Instead, we should be setting topic.bumped_at to the created_at timestamp of the last regular (not a whisper and so on) post on the topic.
Currently when bulk-awarding a badge that can be granted multiple times, users in the CSV file are granted the badge once no matter how many times they're listed in the file and only if they don't have the badge already.
This PR adds a new option to the Badge Bulk Award feature so that it's possible to grant users a badge even if they already have the badge and as many times as they appear in the CSV file.
User flair was given by user's primary group. This PR separates the
two, adds a new field to the user model for flair group ID and users
can select their flair from user preferences now.
For other private messages we have the site setting
personal_email_time_window_seconds (default 20s) which allows
people to edit their post etc. before the email is sent.
This PR makes the Jobs::GroupSmtpEmail enqueuer in the
PostAlerter use the same delay.
<!-- NOTE: All pull requests should have tests (rspec in Ruby, qunit in JavaScript). If your code does not include test coverage, please include an explanation of why it was omitted. -->
This PR backtracks a fair bit on this one https://github.com/discourse/discourse/pull/13220/files.
Instead of sending the group SMTP email for each user via `UserNotifications`, we are changing to send only one email with the existing `Jobs::GroupSmtpEmail` job and `GroupSmtpMailer`. We are changing this job and mailer along with `PostAlerter` to make the first topic allowed user the `to_address` for the email and any other `topic_allowed_users` to be the CC address on the email. This is to cut down on emails sent via SMTP, which is subject to daily limits from providers such as Gmail. We log these details in the `EmailLog` table now.
In addition to this, we have changed `PostAlerter` to no longer rely on incoming email email addresses for sending the `GroupSmtpEmail` job. This was unreliable as a user's email could have changed in the meantime. Also it was a little overcomplicated to use the incoming email records -- it is far simpler to reason about to just use topic allowed users.
This also adds a fix to include cc_addresses in the EmailLog.addressed_to_user scope.
The generated regular expressions did not contain \b which matched
every text that contained the word, even if it was only a substring of
a word.
For example, if "art" was a watched word a post containing word
"artist" matched.
Subclasses must call #delete_user_actions inside build_actions to support user deletion. The method adds a delete user bundle, which has a delete and a delete + block option. Every subclass is responsible for implementing these actions.
Notifying about a tag change sometimes resulted in loading a large
number of users in memory just to perform an exclusion. This commit
prefers to do inclusion (i.e. instead of exclude users X, do include
users in groups Y) and does it in SQL to avoid fetching unnecessary
data that is later discarded.
When a group only has SMTP enabled and not IMAP, we do not
want to enqueue the :group_smtp_email job because using the group's
SMTP credentials for sending user_private_message emails is
handled by the UserNotifications class.
We do not want the :group_smtp_email job to be enqueued because
that uses a reply key instead of the group.email_username
for the reply-to address which is not what we want for SMTP
only, and also creates an IncomingEmail record to prevent IMAP
double syncing which we do not need either.
There is an open question about what happens when IMAP is
enabled after SMTP has been enabled for a while, and also questions
around whether we could do away with :group_smtp_email altogether
and handle everything via EmailLog and UserNotifications, adding
additional columns to the former and modifying the Imap::Sync
class to take this into account...a lot more further testing
for IMAP needs to be done to answer those questions.
For now, this fix should be sufficient to get the correct
reply-to address for user_private_response messages sent in
response to emails sent directly to the group's
email_username SMTP address.

This PR changes the `UserNotification` class to send outbound `user_private_message` using the group's SMTP settings, but only if:
* The first allowed_group on the topic has SMTP configured and enabled
* SiteSetting.enable_smtp is true
* The group does not have IMAP enabled, if this is enabled the `GroupSMTPMailer` handles things
The email is sent using the group's `email_username` as both the `from` and `reply-to` address, so when the user replies from their email it will go through the group's SMTP inbox, which needs to have email forwarding set up to send the message on to a location (such as a hosted site email address like meta@discoursemail.com) where it can be POSTed into discourse's handle_mail route.
Also includes a fix to `EmailReceiver#group_incoming_emails_regex` to include the `group.email_username` so the group does not get a staged user created and invited to the topic (which was a problem for IMAP), as well as updating `Group.find_by_email` to find using the `email_username` as well for inbound emails with that as the TO address.
#### Note
This is safe to merge without impacting anyone seriously. If people had SMTP enabled for a group they would have IMAP enabled too currently, and that is a very small amount of users because IMAP is an alpha product, and also because the UserNotification change has a guard to make sure it is not used if IMAP is enabled for the group. The existing IMAP tests work, and I tested this functionality by manually POSTing replies to the SMTP address into my local discourse.
There will probably be more work needed on this, but it needs to be tested further in a real hosted environment to continue.
It was not clear that replace watched words can be used to replace text
with URLs. This introduces a new watched word type that makes it easier
to understand.
This overhauls the user interface for the group email settings management, aiming to make it a lot easier to test the settings entered and confirm they are correct before proceeding. We do this by forcing the user to test the settings before they can be saved to the database. It also includes some quality of life improvements around setting up IMAP and SMTP for our first supported provider, GMail. This PR does not remove the old group email config, that will come in a subsequent PR. This is related to https://meta.discourse.org/t/imap-support-for-group-inboxes/160588 so read that if you would like more backstory.
### UI
Both site settings of `enable_imap` and `enable_smtp` must be true to test this. You must enable SMTP first to enable IMAP.
You can prefill the SMTP settings with GMail configuration. To proceed with saving these settings you must test them, which is handled by the EmailSettingsValidator.
If there is an issue with the configuration or credentials a meaningful error message should be shown.
IMAP settings must also be validated when IMAP is enabled, before saving.
When saving IMAP, we fetch the mailboxes for that account and populate them. This mailbox must be selected and saved for IMAP to work (the feature acts as though it is disabled until the mailbox is selected and saved):
### Database & Backend
This adds several columns to the Groups table. The purpose of this change is to make it much more explicit that SMTP/IMAP is enabled for a group, rather than relying on settings not being null. Also included is an UPDATE query to backfill these columns. These columns are automatically filled when updating the group.
For GMail, we now filter the mailboxes returned. This is so users cannot use a mailbox like Sent or Trash for syncing, which would generally be disastrous.
There is a new group endpoint for testing email settings. This may be useful in the future for other places in our UI, at which point it can be extracted to a more generic endpoint or module to be included.
Previously we would retry push notifications indefinitely for all errors
except for ExpiredSubscription
Under certain conditions other persistent errors may arise such as a persistent
rate limit.
If we track more than 3 errors in a period of time longer than a day we will
delete the subscription
Also performs a bit of internal cleanup to ensure protected methods really
are private.
This PR improves the UI of bulk select so that its context is applied to the Dismiss Unread and Dismiss New buttons. Regular users (not just staff) are now able to use topic bulk selection on the /new and /unread routes to perform these dismiss actions more selectively.
For Dismiss Unread, there is a new count in the text of the button and in the modal when one or more topic is selected with the bulk select checkboxes.
For Dismiss New, there is a count in the button text, and we have added functionality to the server side to accept an array of topic ids to dismiss new for, instead of always having to dismiss all new, the same as the bulk dismiss unread functionality. To clean things up, the `DismissTopics` service has been rolled into the `TopicsBulkAction` service.
We now also show the top Dismiss/Dismiss New button based on whether the bottom one is in the viewport, not just based on the topic count.
Over the years we accrued many spelling mistakes in the code base.
This PR attempts to fix spelling mistakes and typos in all areas of the code that are extremely safe to change
- comments
- test descriptions
- other low risk areas
Watched words are always regular expressions, despite watched_words_
_regular_expressions being enabled or not. Internally, wildcard
characters are replaced with a regular expression that matches any non
whitespace character.
* FIX: Hide tag watched words if tagging is disabled
These 'autotag' words were shown even if tagging was disabled.
* FIX: Make autotag watched words case insensitive
This commit also fixes the bug when no tag was applied if no other tag
was already present.
We have a few places in the code where we need to validate various email related settings, and will have another soon with the improved group email settings UI. This PR introduces a class which can validate POP3, IMAP, and SMTP credentials and also provide a friendly error message for issues if they must be presented to an end user.
This PR does not change any existing code to use the new service. I have added a TODO to change POP3 validation and the email test rake task to use the new validator post-release.
* FIX: Link notification to first unread post
If a topic with a few posts was posted in a watched category or with a
watched tag, the created notification would always point to the last
post, instead of pointing to the first one.
The root cause is that the query that fetched the first unread post
uses 'TopicUser' records and those are not created by default for
user watching a category or tag. In this case, it should use the
'CategoryUser' or 'TagUser' records.
* DEV: Use named bind variables
The message in logs will now look like:
```
BadgeGranter::GrantError: Failed to backfill 'Some Badge' badge: {:post_ids=>[]}. Reason: ERROR: column "email" does not exist
LINE 6: ...t id as user_id, current_timestamp as granted_at, email from...
```
When the admin creates a new custom field they can specify if that field should be searchable or not.
That setting is taken into consideration for quick search results.
Previously watched words ignored topic titles when applying auto tagging rules.
Also copy has been improved to reflect how the system behaves.
The text hints that we are only watching first post now
Rails 6.1.3.1 deprecates a few API and has some internal changes that break our tests suite, so this commit fixes all the deprecations and errors and now Discourse should be fully compatible with Rails 6.1.3.1. We also have a new release of the rails_failover gem that's compatible with Rails 6.1.3.1.
This PR adds a new category setting which is a column in the `categories` table, `allow_unlimited_owner_edits_on_first_post`.
What this does is:
* Inside the `can_edit_post?` method of `PostGuardian`, if the current user editing a post is the owner of the post, it is the first post, and the topic's category has `allow_unlimited_owner_edits_on_first_post`, then we bypass the check for `LimitedEdit#edit_time_limit_expired?` on that post.
* Also, similar to wiki topics, in `PostActionNotifier#after_create_post_revision` we send a notification to all users watching a topic when the OP is edited in a topic with the category setting `allow_unlimited_owner_edits_on_first_post` enabled.
This is useful for forums where there is a Marketplace or similar category, where topics are created and then updated indefinitely by the OP rather than the OP making new topics or additional replies. In a way this acts similar to a wiki that only one person can edit.
To add an extra layer of security, we sanitize settings before shipping them to the client. We don't sanitize those that have the "html" type.
The CookedPostProcessor already uses Loofah for sanitization, so I chose to also use it for this. I added it to our gemfile since we installed it as a transitive dependency.
