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.
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.
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.
This reverts commit 20780a1eee.

Upgrades Rails to latest, this version has better compatibility
with Ruby 2.7
During the upgrade we needed a new cleaner mechanism for configuring
message bus.
All tests are green.
If anything weird pops up please revert.
We have the `# frozen_string_literal: true` comment on all our
files. This means all string literals are frozen. There is no need
to call #freeze on any literals.
For files with `# frozen_string_literal: true`
```
puts %w{a b}[0].frozen?
=> true
puts "hi".frozen?
=> true
puts "a #{1} b".frozen?
=> true
puts ("a " + "b").frozen?
=> false
puts (-("a " + "b")).frozen?
=> true
```

* DEV: Use `render_json_error` (Adds specs for Admin::GroupsController)
* DEV: Use a specific error on blank category slug (Fixes a `render_json_error` warning)
* DEV: Use a specific error on reviewable claim conflict (Fixes a `render_json_error` warning)
* DEV: Use specific errors in Admin::UsersController (Fixes `render_json_error` warnings)
* FIX: PublishedPages error responses
* FIX: TopicsController error responses (There was an issue of two separate `Topic` instances for the same record. This makes sure there's only one up-to-date instance.)
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
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.
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.
* 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.
* REFACTOR: Remove Tilt/ES6ModuleTranspiler
* FIX: We need to skip users with associated reviewables when auto-approving them
* Update spec/initializers/track_setting_changes_spec.rb
* Update spec/initializers/track_setting_changes_spec.rb

Tracking down concurrency issues from backtraces and manual repros is a fraught process.
Sometimes you've just got to get your hands dirty and do a live debug.
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
This is not used in core or official plugins, and has been printing a deprecation notice since v2.3.0beta4. All OpenID 2.0 code and dependencies have been dropped. The user_open_ids table remains for now, in case anyone has missed the deprecation notice, and needs to migrate their data.
Context at https://meta.discourse.org/t/-/113249
Out-of-the-box Oj uses :object mode, this shifts us to use :compat mode
by default which is safer.
It means any de-serialization going forward will default to this mode.
If we wish to serialize or deserialize arbitrary objects going forward with
no json interfaces we will have to opt in.
- Refactor source_url to avoid using eval in development
- Precompile handlebars in development
- Include template compilers when running qunit
- Remove unsafe-eval in development CSP
- Include unsafe-eval only for qunit routes in development
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.
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.
Under extreme load on large databases certain regular jobs can take quite
a while to run. We need to ensure we never starve a sidekiq from running
mini scheduler, cause without it we are unable to queue stuff such as
heartbeat jobs.
This adds a 1 minute rate limit to all JS error reporting per IP. Previously
we would only use the global rate limit.
This also introduces DISCOURSE_ENABLE_JS_ERROR_REPORTING, if it is set to
false then no JS error reporting will be allowed on the site.
Previously the default stack suppressor in rack-mini-profiler was excluding
the plugin directory.
This made islolating issues more complicated cause you needed to defer to
pp=full-backtrace which is both slow and noisy
If enabled, this will fire a webhook whenever a user's notification has
been created. This could potentially be a lot of data depending on your
forum, and should be used carefully since it includes everything all users
will see in their feeds.
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
This is useful when a backup is restored on a staging site or in a development environment. It also deletes all existing push subscriptions because they get invalid when the keys change.
Sometimes we would like to create a base image without any DB access, this
assists in creating custom base images with custom plugins that already
includes `public/assets`
Following this change set you can run:
```
SPROCKETS_CONCURRENT=1 DONT_PRECOMPILE_CSS=1 SKIP_DB_AND_REDIS=1 RAILS_ENV=production bin/rake assets:precompile
```
Then it is straight forward to create a base image without needing a DB or
Redis.
* Support private uploads in S3
* Use localStore for local avatars
* Add job to update private upload ACL on S3
* Test multisite paths
* update ACL for private uploads in migrate_to_s3 task
This adds support for DISCOURSE_ENABLE_PERFORMANCE_HTTP_HEADERS
when set to `true` this will turn on performance related headers
```text
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
This backend is a bit faster and well tested, this is part of a longer
term plan to have a `backend: :memory, threaded: false` type config for
message bus which we can use in test.
The threading in message bus causes all sorts of surprises in test, it will
be nice not to be beholden to them.
Adds `DISCOURSE_MESSAGE_BUS_REDIS_ENABLED` env var, that when set
to true, will allow Discourse to connect to a different redis
instance for MessageBus needs.
When enabled you can configure the same env vars user for redis,
but prefixed by `MESSAGE_BUS`, eg:
`DISCOURSE_MESSAGE_BUS_REDIS_HOST`
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging

```
Benchmark.ips do |b|
b.report("simple") do
User.first
end
end
ActiveSupport::Notifications.notifier.listeners_for("sql.active_record").clear

b.report("simple") do
User.first
end
end

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
Without forcing a reload on start internal state in the accelerator can be
off. In Rails 5 not translation is being called so this is not an issue but
in 6 it is called earlier on.
* 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.
Since Rails 5.2, the behavior of `attribute_changed?` inside `after_save` callbacks has changed, so we need to use `saved_change_to_attribute` instead. The site setting local_process_provider in test mode was covering up the issue.
If you turn it on now, default all users to approved since they were
previously. Also support approving a user that doesn't have a reviewable
record (it will be created first.)
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.
Includes support for flags, reviewable users and queued posts, with REST API
backwards compatibility.

This cleans up logster configuration a bit cause we no longer have to
check if we respond_to anything and keeps the logster limit properly
documented
Followup on da578e92
Ruby 2.5.3 has an upatched issue that crashes unicorn after fork:
https://bugs.ruby-lang.org/issues/14634
This will be patched in 2.5.4 however for now just warn people dev is slower
and disable async logging on the older rubies
On the first migration, trying to access the users table will throw an
error in PostgreSQL's log which has been confusing since users will
report it to us when rebuild fails.
This avoids require dependency on method_profiler and anon cache.
It means that if there is any change to these files the reloader will not pick it up.
Previously the reloader was picking up the anon cache twice causing it to double load on boot.
This caused warnings.
Long term my plan is to give up on require dependency and instead use:
https://github.com/Shopify/autoload_reloader
This provides us with instrumentation missing after rails upgrade
Latest version of rails uses exec_params internally which is no longer
routed to intercepted methods in mini profiler 1.0.0
ActiveRecord defines automatic scopes for enums, the Poll model defines
an enum for `{open: 1}` this mean Rails wants the scope `Poll.all.open`
to work which in turn means it has to override `open` which is defined
privately.
Rails feature req exists for: https://github.com/rails/rails/issues/34599
which will allow us to define enums without scopes which would resolve this
a lot more cleaner.

This moves us away from the delayed drops pattern which
was problematic on two counts. First, it uses a hardcoded "delay for"
duration which may be too short for certain deployment strategies.
Second, delayed drop doesn't ensure that it only runs after
the latest application code has been deployed. If the migration runs
and the application code fails to deploy, running the migration after
"delay for" has been met will cause the application to blow up.
The new strategy allows post deployment migrations to be skipped if the
env `SKIP_POST_DEPLOYMENT_MIGRATIONS` is provided.
```
SKIP_POST_DEPLOYMENT_MIGRATIONS=1 rake db:migrate
-> deploy app servers
SKIP_POST_DEPLOYMENT_MIGRATIONS=0 rake db:migrate
```
To aid with the generation of a post deployment migration, a generator
has been added. Simply run `rails generate post_migration`.
This commit also cleans up a bunch of pointless noise each time we boot app
- narrative was loading i18n cause redefinition of consts
- discourse.rb was loaded twice as was auth
- bin/unicorn now does all the smart things and boots unicron in dev
- bin/rails s will boot unicorn with no params
- remove bin/puma which only causes confusion
