systemd service agent

• https://github.com/troydhanson/uthash (header file only)

Initialization of the service agent requires a directory name to be provided. In this directory, the following files will be written:

• /logs -- directory where log files will be written

• svcagt_exclude_services.txt -- list of services to be excluded (one per line)

• svcagt_goal_states.txt -- list of services that have been started or stopped by service agent -- and the state.

Two types of test can be run. The systemd tests invoke systemctl, and actually start and stop services. The pass-fail tests use a mock systemctl, so that code paths can be tested without actually invoking systemctl.

Before you can run the systemd tests, you need to run a setup script:

1. cd .../service-agent-c/tests
2. python setup_svcagt_services.py

The setup creates a mock_systemctl. It also creates and installs three test services for use with the systemd tests.

To run the systemd tests :

1. cd .../service-agent-c/tests
2. . start_systemd_test.sh
3. In a separate terminal window, run test_svcagt

To run the pass-fail tests :

1. cd .../service-agent-c/tests
2. ../build/tests/test_svcagt
