Class Method Details

.cache_backend ⇒ Object

By default, the backend is Rails.cache, which uses ActiveSupport::Cache::RedisStore. Since loading ApplicationSetting can cause a significant amount of load on Redis, let's cache it in memory.

# File 'app/models/application_setting.rb', line 723

def self.cache_backend
  Gitlab::ProcessMemoryCache.cache_backend
end

.check_schema! ⇒ Object

Due to the frequency with which settings are accessed, it is likely that during a backup restore a running GitLab process will insert a new `application_settings` row before the constraints have been added to the table. This would add an extra row with ID 1 and prevent the primary key constraint from being added, which made ActiveRecord throw a IrreversibleOrderError anytime the settings were accessed (gitlab.com/gitlab-org/gitlab/-/issues/36405). To prevent this from happening, we do a sanity check that the primary key constraint is present before inserting a new entry.
