FEATURE: Allow hotlinked media to be blocked (#16940)
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.

FIX: Skip pulling hotlinked images for nil user bio (#16901) 2022-05-24 11:52:13 +01:00
David Taylor bf6f8299a7 FEATURE: Pull hotlinked images immediately after posting
Previously, with the default `editing_grace_period`, hotlinked images were pulled 5 minutes after a post is created. This delay was added to reduce the chance of automated edits clashing with user edits.

This commit refactors things so that we can pull hotlinked images immediately. URLs are immediately updated in the post's `cooked` HTML. The post's raw markdown is updated later, after the `editing_grace_period`.

This involves a number of behind-the-scenes changes including:

- Schedule Jobs::PullHotlinkedImages immediately after Jobs::ProcessPost. Move scheduling to after the `update_column` call to avoid race conditions

- Move raw changes into a separate job, which is delayed until after the ninja-edit window

- Move disable_if_low_on_disk_space logic into the `pull_hotlinked_images` job

- Move raw-parsing/replacing logic into `InlineUpload` so it can be easily be shared between `UpdateHotlinkedRaw` and `PullUserProfileHotlinkedImages`

David Taylor 0baabafa9d DEV: Map already-downloaded hotlinked images in post_process_cooked

PERF: Speed up secure media and ACL sync rake tasks (#16849)
Incorporates learnings from /t/64227:

* Changes the code to set access control posts in the rake
  task to be an efficient UPDATE SQL query.
  The original version was timing out with 312017 post uploads,
  the new query took ~3s to run.
* Changes the code to mark uploads as secure/not secure in
  the rake task to be an efficient UPDATE SQL query rather than
  using UploadSecurity. This took a very long time previously,
  and now takes only a few seconds.
* Spread out ACL syncing for uploads into jobs with batches of
  100 uploads at a time, so they can be parallelized instead
  of having to wait ~1.25 seconds for each ACL to be changed
  in S3 serially.

One issue that still remains is post rebaking. Doing this serially
is painfully slow. We have a way to do this in sidekiq via PeriodicalUpdates
but this is limited by max_old_rebakes_per_15_minutes. It would
be better to fan this rebaking out into jobs like we did for the
ACL sync, but that should be done in another PR.

FEATURE: Promote polymorphic bookmarks to default and migrate (#16729)
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.

FEATURE: Polymorphic bookmarks pt. 3 (reminders, imports, exports, refactors) (#16591)
A bit of a mixed bag, this addresses several edge areas of bookmarks and makes them compatible with polymorphic bookmarks (hidden behind the `use_polymorphic_bookmarks` site setting). The main ones are:

* ExportUserArchive compatibility
* SyncTopicUserBookmarked job compatibility
* Sending different notifications for the bookmark reminders based on the bookmarkable type
* Import scripts compatibility
* BookmarkReminderNotificationHandler compatibility

This PR also refactors the `register_bookmarkable` API so it accepts a class descended from a `BaseBookmarkable` class instead. This was done because we kept having to add more and more lambdas/properties inline and it was very messy, so a factory pattern is cleaner. The classes can be tested independently as well.

Some later PRs will address some other areas like the discourse narrative bot, advanced search, reports, and the .ics endpoint for bookmarks.

FEATURE: Let sites add a sitemap.xml file. (#16357)
* 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`.

Martin Brennan 9f2138dc92
FEATURE: Add a sidekiq job for syncing S3 ACLs (#16449)
Sometimes we need to update a _lot_ of ACLs on S3 (such as when secure media
is enabled), and since it takes ~1s per upload to update the ACL, this is
best spread out over many jobs instead of having to do the whole thing serially.

In future, it will be better to have a job that can be run based on
a column on uploads (e.g. acl_stale) so we can track progress, similar
to how we can set the baked_version to nil to rebake posts.

David Taylor 39ac476db6 FIX: Do not attempt to pull_hotlinked_image for raw_html
raw_html posts (i.e. those which are pulled as part of our comments integration) don't go through our markdown pipeline, so `upload://` URLs are not supported. Running pull_hotlinked_images will break any images in the post.

In future we may add support for pulling hotlinked images in these posts. But for now, disabling it will stop it breaking images.

FEATURE: Polymorphic bookmarks pt. 1 (CRUD) (#16308)
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.

commit 6d422a8033. A bookmark reminder
will fire only if reminder_last_sent_at is null, but before that it

sometimes reminder_at continues to exist even after a reminder fired.

Michael Brown 3bf3b9a4a5 DEV: pull email address validation out to a new EmailAddressValidator

David Taylor 3a85c4d680 DEV: Ensure Sidekiq job arguments have stringified keys
The latest version of Sidekiq introduced a warning when jobs are queued with arguments which 'do not stringify to JSON safely'. In the vast majority of cases, this is because a hash is passed with symbols as keys. When those args are passed to the job, the keys will be stringified.

Our job wrapper already takes care of this issue by calling '.with_indifferent_access' on the args before passing them to `#execute`, so we don't need to change anything about our use. All we need to do is satisfy Sidekiq's warning system by 'stringifying' all the keys before enqueuing the job.

FEATURE: Scheduled problem checks for admin dashboard (#15327)
This commit introduces scheduled problem checks for the admin dashboard, which are long running or otherwise cumbersome problem checks that will be run every 10 minutes rather than every time the dashboard is loaded. If these scheduled checks add a problem, the problem will remain until it is cleared or until the scheduled job runs again.

An example of a check that should be scheduled is validating credentials against an external provider.

This commit also introduces the concept of a `priority` to the problems generated by `AdminDashboardData` and the scheduled checks. This is `low` by default, and can be set to `high`, but this commit does not change any part of the UI with this information, only adds a CSS class.

post.topic_id as the canonical topic_id for bookmarks, then we
don't need to remember to update both columns if the bookmarked
post moves to another topic.

David Taylor 31db83527b DEV: Introduce PresenceChannel API for core and plugin use
PresenceChannel aims to be a generic system for allow the server, and end-users, to track the number and identity of users performing a specific task on the site. For example, it might be used to track who is currently 'replying' to a specific topic, editing a specific wiki post, etc.

A few key pieces of information about the system:
- PresenceChannels are identified by a name of the format `/prefix/blah`, where `prefix` has been configured by some core/plugin implementation, and `blah` can be any string the implementation wants to use.
- Presence is a boolean thing - each user is either present, or not present. If a user has multiple clients 'present' in a channel, they will be deduplicated so that the user is only counted once
- Developers can configure the existence and configuration of channels 'just in time' using a callback. The result of this is cached for 2 minutes.
- Configuration of a channel can specify permissions in a similar way to MessageBus (public boolean, a list of allowed_user_ids, and a list of allowed_group_ids). A channel can also be placed in 'count_only' mode, where the identity of present users is not revealed to end-users.
- The backend implementation uses redis lua scripts, and is designed to scale well. In the future, hard limits may be introduced on the maximum number of users that can be present in a channel.
- Clients can enter/leave at will. If a client has not marked itself 'present' in the last 60 seconds, they will automatically 'leave' the channel. The JS implementation takes care of this regular check-in.
- On the client-side, PresenceChannel instances can be fetched from the `presence` ember service. Each PresenceChannel can be used entered/left/subscribed/unsubscribed, and the service will automatically deduplicate information before interacting with the server.
- When a client joins a PresenceChannel, the JS implementation will automatically make a GET request for the current channel state. To avoid this, the channel state can be serialized into one of your existing endpoints, and then passed to the `subscribe` method on the channel.
- The PresenceChannel JS object is an ember object. The `users` and `count` property can be used directly in ember templates, and in computed properties.
- It is important to make sure that you `unsubscribe()` and `leave()` any PresenceChannel objects after use

An example implementation may look something like this. On the server:

```ruby
register_presence_channel_prefix("site") do |channel|
  next nil unless channel == "/site/online"
  PresenceChannel::Config.new(public: true)
end
```

And on the client, a component could be implemented like this:

```javascript
import Component from "@ember/component";
import { inject as service } from "@ember/service";

export default Component.extend({
  presence: service(),
  init() {
    this._super(...arguments);
    this.set("presenceChannel", this.presence.getChannel("/site/online"));
  },
  didInsertElement() {
    this.presenceChannel.enter();
    this.presenceChannel.subscribe();
  },
  willDestroyElement() {
    this.presenceChannel.leave();
    this.presenceChannel.unsubscribe();
  },
});
```

With this template:

```handlebars
Online: {{presenceChannel.count}}
<ul>
  {{#each presenceChannel.users as |user|}} 
    <li>{{avatar user imageSize="tiny"}} {{user.username}}</li>
  {{/each}}
</ul>
```

FIX: Do not send emails to mailing_list_mode subscribers for PMs (#14159)
This bug was introduced by f66007ec83.

In PostJobsEnqueuer we previously did not fire the after_post_create
event and after_topic_create event for private message topics. This was
changed in the above commit in order to publish message bus messages
for topic tracking state updates. Unfortunately this caused the
NotifyMailingListSubscribers job to be enqueued for all posts including
private messages, and admins and the users involved in the PMs got
emailed the contents of the PMs if they had mailing list mode enabled.

Luckily the impact of this was mitigated by a Guardian#can_see? check
for each mailing list mode user in the NotifyMailingListSubscribers job.
We never want to notify mailing list mode subscribers for private messages
so an early return has been added there, plus the logic in PostJobsEnqueuer
has been fixed, and tests have been added to that class where there were
none before.

FEATURE: Display unread and new counts for messages. (#14059)
There are certain design decisions that were made in this commit.

Private messages implements its own version of topic tracking state because there are significant differences between regular and private_message topics. Regular topics have to track categories and tags while private messages do not. It is much easier to design the new topic tracking state if we maintain two different classes, instead of trying to mash this two worlds together.

One MessageBus channel per user and one MessageBus channel per group. This allows each user and each group to have their own channel backlog instead of having one global channel which requires the client to filter away unrelated messages.

FEATURE: Initial implementation of direct S3 uploads with uppy and stubs (#13787)
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.

This PR fixes a couple of issues related to group SMTP:

1. When running the group SMTP job, we were exiting early if the email was for the OP because of an IMAP race condition. However this causes issues when replying as a new topic for an existing SMTP topic, as the recipient does not get the OP email which can cause threading problems.
2. When sending emails for a new topic spun out like the issue in 1., we are not maintaining the original subject/topic title because that is based on the incoming email record, which we were not doing because the group SMTP email was never sent because of issue 1.

There was an issue with the TopicTimerEnqueuer where any timer
that failed to enqueue_typed_job with an error would prevent
all other pending timers after the one that errored from running.

To mitigate this we just capture the error and log it (so we can
still fix it if needed for bug crushing) and proceed with the
rest of the timer enqueues.

The commit https://github.com/discourse/discourse/pull/13544 highlighted
this issue originally in hosted sites.

FIX: Handle SMTPServerBusy for group smtp email (#13632)
Use the `sidekiq_retry_in` code from Jobs::UserEmail in group SMTP. Also we don't need to keep `seconds_to_delay` -- sidekiq uses the default delay calculation if you return 0 or nil from the block. See 3330df0ee3/lib/sidekiq/job_retry.rb (L216-L234) for sidekiq default retry delay logic.

I experimented with extracting this into a concern or a module, but `sidekiq_retry_in` is quite magic and it would not allow me to abstract away into a module that calls some method specificall in the child job class.

I would love to write tests for this, but it does not seem possible (not sure if its because of our test
setup) to write tests that test sidekiq's retry capability, and I am not sure if we should be anyway. Initial addition
to UserEmail did not test this functionality

FEATURE: Use group SMTP job and mailer instead of UserNotifications change (#13489)
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.
