DEV: Allow writes to PG even if Redis is readonly mode.
Previously, I thought it was better to drop the site into reading mode
when Redis has failed over to the replica but it created more errors
while Redis is in readonly mode since ActiveRecord would prevent us from
writing to PG even though PG is up.

DEV: Enable readonly mode for all multisite sites when PG goes down.
The risk here is that the database for one site goes down in the multisite setup and we drop everything to readonly mode. However, I discussed this with Sam and we agree that one database having problem is very rare. Most of the time, it is the entire DB cluster that goes down.

Sam Saffron 25f1f23288
FEATURE: Stricter rules for user presence
Previously we would consider a user "present" and "last seen" if the
browser window was visible.

This has many edge cases, you could be considered present and around for
days just by having a window open and no screensaver on.

Instead we now also check that you either clicked, transitioned around app
or scrolled the page in the last minute in combination with window
visibility

This will lead to more reliable notifications via email and reduce load of
message bus for cases where a user walks away from the terminal

Martin Brennan 097851c135
FIX: Change secure media to encompass attachments as well (#9271)
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.

Gerhard Schlager 8022e51179 FIX: Failed to restore backups from versions without translation overrides
Rails calls I18n.translate during initialization and by default translation overrides are used. Database migrations would fail if the system tried to migrate from an old version that didn't have the `translation_overrides` table with all its columns yet.

This makes restoring really old backups work again. Running `DISABLE_TRANSLATION_OVERRIDES=1 rake db:migrate` will allow you to upgrade such an old database as well.

Support for transpiling `.js` files (#9160)
* Remove some `.es6` from comments where it does not matter

* Use a post processor for transpilation

This will allow us to eventually use the directory structure to
transpile rather than the extension.

* FIX: Some errors and clean up in confirm-new-email

It would throw an error if the webauthn element wasn't present.
Also I changed things so that no-module is not explicitly
referenced.

* Remove `no-module`

Instead we allow a magic comment: `// discourse-skip-module` to prevent
the asset pipeline from creating a module.

* DEV: Enable babel transpilation based on directory

If it's in `app/assets/javascripts/dicourse` it will be transpiled
even without the `.es6` extension.

PERF: avoid shelling to get hostname aggressively
Previously we had many places in the app that called `hostname` to get
hostname of a server. This commit replaces the pattern in 2 ways

1. We cache the result in `Discourse.os_hostname` so it is only ever called once

2. We prefer to use Socket.gethostname which avoids making a shell command

This improves performance as we are not spawning hostname processes throughout
the app lifetime

Robin Ward ce78eff888 FIX: Migration paths were being forgotten
According to the [Rails
Source](https://github.com/rails/rails/blob/master/activerecord/lib/active_record/railties/databases.rake#L20)
the `ActiveRecord::Migrator.migrations_paths` are overwritten with the
value of `ActiveRecord::Tasks::DatabaseTasks.migrations_paths` every
time the config is loaded.

This caused a bug for Discourse development where if you ran:

`rake db:drop db:create db:migrate` in one line, you would not get our
post migrations, as those had a custom value for `migrations_paths`.

The fix is to use `ActiveRecord::Tasks::DatabaseTasks.migrations_paths`
to set up all our custom paths. Everything seems to work as expected.

Daniel Waterworth 4c9ed7bd85 FIX: Fix rake db:create after zeitwerk changes
Post-zeitwerk, rails has deprecated autoloading modules during
initialization and forces all autoloaded modules to be reloaded after
initialization.

Requiring the file explicitly prevents autoloading and therefore
prevents the state on SiteSetting being trashed which was causing the
problem here.

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.

Sam Saffron 1f47ed1ea3 PERF: message_bus will be deferred by server when flooded
The message_bus performs a fair amount of work prior to hijacking requests
this change ensures that if there is a situation where the server is flooded
message_bus will inform client to back off for 30 seconds + random(120 secs)

This back-off is ultra cheap and happens very early in the middleware.

It corrects a situation where a flood to message bus could cause the app
to become unresponsive

MessageBus update is here to ensure message_bus gem properly respects
Retry-After header and status 429.

Under normal state this code should never trigger, to disable raise the
value of DISCOURSE_REJECT_MESSAGE_BUS_QUEUE_SECONDS, default is to tell
message bus to go away if we are queueing for 100ms or longer

X-Redis-Calls: 10     # number of redis calls
X-Redis-Time: 1.02    # redis time in seconds
X-Sql-Commands: 102   # number of SQL commands
X-Sql-Time: 1.02      # duration in SQL in seconds
X-Queue-Time: 1.01    # time the request sat in queue (depends on NGINX)
```

To get queue time NGINX must provide: HTTP_X_REQUEST_START

We do not recommend you enable this without thinking, it exposes information
about what your page is doing, usually you would only enable this if you
intend to strip off the headers further down the stream in a proxy

FEATURE: Automatically generate optimized site metadata icons (#7372)
This change automatically resizes icons for various purposes. Admins can now upload `logo` and `logo_small`, and everything else will be auto-generated. Specific icons can still be uploaded separately if required.

## Core

- Adds an SiteIconManager module which manages automatic resizing and fallback

- Icons are looked up in the OptimizedImage table at runtime, and then cached in Redis. If the resized version is missing for some reason, then most icons will fall back to the original files. Some icons (e.g. PWA Manifest) will return `nil` (because an incorrectly sized icon is worse than a missing icon). 

- `SiteSetting.site_large_icon_url` will return the optimized version, including any fallback. `SiteSetting.large_icon` continues to return the upload object. This means that (almost) no changes are required in core/plugins to support this new system.

- Icons are resized whenever a relevant site setting is changed, and during post-deploy migrations

## Wizard

- Allows `requiresRefresh` wizard steps to reload data via AJAX instead of a full page reload

- Add placeholders to the **icons** step of the wizard, which automatically update from the "Square Logo"

- Various copy updates to support the changes

- Remove the "upload-time" resizing for `large_icon`. This is no longer required.

## Site Settings UX

- Move logo/icon settings under a new "Branding" tab

- Various copy changes to support the changes

- Adds placeholder support to the `image-uploader` component

- Automatically reloads site settings after saving. This allows setting placeholders to change based on changes to other settings

- Upload site settings will be assigned a placeholder if SiteIconManager `responds_to?` an icon of the same name

## Dashboard Warnings

- Remove PWA icon and PWA title warnings. Both are now handled automatically.

## Bonus

- Updated the sketch logos to use @awesomerobot's new high-res designs

DEV: Replace site_setting_saved DiscourseEvent with site_setting_changed (#7401)
* DEV: Replace site_setting_saved DiscourseEvent with site_setting_changed

site_setting_saved is confusing for a few reasons:
- It is attached to the after_save of the ActiveRecord model. This is confusing because it only works 'properly' with the db_provider
- It passes the activerecord model as a parameter, which is confusing because you get access to the 'database' version of the setting, rather than the ruby setting. For example, booleans appear as 'y' or 'n' strings.
- When the event is called, the local process cache has not yet been updated. So if you call SiteSetting.setting_name inside the event handler, you will receive the old site setting value

I have deprecated that event, and added a new site_setting_changed event. It passes three parameters:
- Setting name (symbol)
- Old value (in ruby format)
- New value (in ruby format)

It is triggered after the setting has been persisted, and the local process cache has been updated.

This commit also includes a test case which describes the confusing behavior. This can be removed once site_setting_saved is removed.

David Taylor c687e2b921 FIX: Use `saved_change_to_value?` in site_setting_saved event

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.
