Tripal Daemon

This module is meant to provide a simple means of creating a robust command-line-driven, fully bootstrapped PHP Daemon. It uses the PHP-Daemon (https://github.com/shaneharter/PHP-Daemon) Library to create the Daemon (via the Libraries API) in order to not re-invent the wheel ;-).

FEATURES

• Provides a Drush interface to start/stop your Daemon.
• Your daemon starts in the background and is detached from the current terminal.
• Daemon will run all Tripal Jobs submitted within 20 seconds.
• A log including the number of jobs executed, their identifiers and results.
• Lock Files, Automatic restart (8hrs default) and Built-in Signal Handling & Event Logging are only a few of the features provided by the Daemon API making this a fully featured & robust Daemon.

REQUIREMENTS

• Libraries API (https://www.drupal.org/project/libraries)
• PHP-Daemon Library version 2.0 (https://github.com/shaneharter/PHP-Daemon)
