Class Method Details

._semantic_logger_original_new ⇒ Object

Keep a handle on the genuine constructor so that callers which supply a real log destination still get a real logger (see #new below).

alias _semantic_logger_original_new new

.logger_outputs_to?(*_args) ⇒ Boolean

Prevent Rails from trying to merge/broadcast loggers (e.g. ActiveRecord's console hook and rails server's log_to_stdout). SemanticLogger already multiplexes through its own appenders, and SemanticLogger::Logger does not implement #broadcast_to, so the merge path would otherwise raise.

Returns:

  • (Boolean)

  true
end

.new(*args, **kwargs) ⇒ Object

Historically every ActiveSupport::Logger.new(...) call was redirected to SemanticLogger, silently discarding the requested destination. That broke third-party callers such as Webpacker's ActiveSupport::Logger.new(STDOUT), whose output never reached STDOUT (issue #141). Only redirect to SemanticLogger when no destination is supplied; otherwise honor the caller and build a genuine logger pointed at the requested destination.
