.app_root ⇒ Object

The project root the harness serves. Defaults to the current working directory; framework editions set it to the framework's root at boot (ask-rails-harness sets it to ::Rails.root).

end

.cleanup! ⇒ Object

Prune old sessions and audit logs based on configuration limits.

Removes sessions older than max_session_age seconds, and limits the total number of sessions to max_sessions (deleting the oldest first). Audit log entries older than the oldest kept session are also removed.

end

.connect_database! ⇒ Object

Establish a standalone ActiveRecord connection when the host hasn't (Rails apps are already connected and are left untouched).

Connection sources, in order: ASK_DATABASE_URL, config/database.yml.

  ActiveRecord::Base.establish_connection(config) if config
rescue StandardError => e
  warn "[ask-ruby-harness] database connect failed: #{e.message}"
end

.database_config_for(name) ⇒ Object

Config for a NAMED database. Resolution order:

1. the host app's own configurations registry (Rails multi-DB —
 resolves credentials/ENV for us),
2. config/database.yml, the environment section's key.

  section = database_yaml_section
  config = section[name] if section.is_a?(Hash) && section[name].is_a?(Hash)
  sanitize_database_config(config)
end

.database_configured? ⇒ Boolean

Whether a connection spec is defined. Uses the pool presence, not connected? — ActiveRecord's connected? stays false until a connection is actually checked out, while pool.with_connection establishes lazily on first use.

Returns:

  • (Boolean)
