MessageBus::Diagnostics allows anyone with access to carry out certain
operations that may result in a denial of service. The impact of this is
greater on multisiite clusters.
It makes much more sense for these to be GlobalSettings, since, in
multisite clusters, only the default site's settings would be respected.

This commit adds the RailsMultisite middleware in test mode when Rails.configuration.multisite is true. This allows for much more realistic integration testing. The `multisite_spec.rb` file is rewritten to avoid needing to simulate a middleware stack.
* FEATURE: Cache CORS preflight requests for 2h
Browsers will cache this for 5 seconds by default. If using MessageBus
in a different domain, Discourse will issue a new long polling, by
default, every 30s or so. This means we would be issuing a new preflight
request **every time**. This can be incredibly wasteful, so let's cache
the authorization in the client for 2h, which is the maximum Chromium
allows us as of today.
* fix tests
Sidekiq was failing to boot in dev due to the following error. It seems
like constantizing stuff before the autoloader has kicked in caused
stuff to go weird. Root cause has not been identified but there is no
reason for us to have to warm up the cache during the initialization of
Rails.

Take 2 of https://github.com/discourse/discourse/pull/13466.
Fixes a few issues with the original PR:
- color definition stylesheet target now includes the theme id, to avoid themes set to use the default color scheme loading the same stylesheet
- changes the internal cache key for color definition stylesheet to reset the pre-existing cache
When editing the first post for the topic we do two AJAX requests
to two separate controllers in this order:
PUT /t/topic-name
PUT /posts/2489523
This causes two post revisor calls, which end up triggering the
:post_edited DiscourseEvent twice. This is then picked up and sent
as a WebHook event twice. However we do not need to send a :post_edited
webhook event if the first post is being edited and topic_changed is
true from the :post_edited DiscourseEvent, because a second event will
shortly come through for just the post.

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
The auto restart logic was sending a USR2 to the parent process without checking what the parent process actually was. In some situations, it might not be the `bin/unicorn` supervisor.
This commit switches to use a global variable for the supervisor PID. This will be much less prone to unexpected behavior.
This commit adds a listener on (almost) all `.rb` files in the repository. When a change occurs, it checks whether Zeitwerk is responsible for autoloading it. If not, a warning will be printed to the console and the server will be automatically restarted. Optionally, you can pass the `AUTO_RESTART=0` environment variable to prevent auto-restart.
* FEATURE: add support for like webhooks
Add support for like webhooks. Webhook events only send on user membership
in the defined webhook group filters.
This also fixes group webhook events, as before this was never used, and
the logic was not correct.
Adds a webhook to notify when a reviewable score is updated.
This is different from created or status changed as additional flags can
roll in and update the score without updating status. Useful for applications
looking to integrate in with Discourse's scores
This filter hides reviewables with a score lower than the "reviewable_low_priority_threshold" setting. We only use reviewables that already met this threshold to calculate the Medium and High priority filters.
Fixes `Rack::Lint::LintError: a header value must be a String, but the value of 'Retry-After' is a Integer`. (see: 14a236b4f0/lib/rack/lint.rb (L676))
I found it when I got flooded by those warning a while back in a test-related accident 😉 (ember CLI tests were hitting a local rails server at a fast rate)
The logster initializer tries to adds RailsMultisite::Formatter to the STDOUT logger. In production, the lograge initializer then removes the RailsMultisite:Formatter because the JSON log will include the database.
e10a74694a used `Rails.application.reloader.to_prepare` to defer running the 100-logster initializer, which meant it ran **after** 101-lograge. This meant that we were writing JSON logs with a non-json text prefix.
The `to_prepare` was added because our freedom-patches are now deferred using `to_prepare`, and some initializers were relying on the freedom patches. However, following 1533cbb38b, we decided to load the RailsMultisite freedom patch without `to_prepare`. Therefore, `005-site_settings` and `100-logster` no longer need to use `to_prepare`. Removing it means that these initializers are back to running in sequential order, and the logging issue will be resolved.
The only remaining initializer which depends on freedom patches is `100-i18n`. I've added a comment to explain why.
Get rid of deprecation related to Zeitwerk autoloader.
Original PR was reverted because of multisite bug #12381 - thank you @davidtaylorhq for fixing it.
I added the last commit to fix that multisite problem.
- Bump rails_failover for new per-backend callback feature
- If the master backend fails over, make all sites readonly. And vice-versa for fallback
- If a single backend fails over, make that individual site readonly. And vice-versa for fallback
- When a single backend fails, also check connection to the master backend
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.
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.
