This is a copy of github.com/agis/ruby-sdnotify as of commit cca575c The only changes made was “rehoming” it within the Puma module to avoid namespace collisions and applying standard’s code formatting style.

SdNotify is a pure-Ruby implementation of sd_notify(3). It can be used to notify systemd about state changes. Methods of this package are no-op on non-systemd systems (eg. Darwin).

The API maps closely to the original implementation of sd_notify(3), therefore be sure to check the official man pages prior to using SdNotify.
