The status of the Mailman master process can be queried from the command line. It’s clear at this point that nothing is running.
>>> command = cli('mailman.commands.cli_status.status')
The status is printed to stdout and a status code is returned.
>>> command('mailman status') GNU Mailman is not running
We can simulate the master starting up by acquiring its lock.
>>> from datetime import timedelta >>> from flufl.lock import Lock >>> lock = Lock(config.LOCK_FILE) >>> lock.lock(timeout=timedelta(seconds=20)) >>> ignore = cleanups.callback(lock.unlock, unconditionally=True)
Getting the status confirms that the master is running.
>>> command('mailman status') GNU Mailman is running (master pid: ...
We shut down the master and confirm the status.
>>> lock.unlock(unconditionally=True) >>> command('mailman status') GNU Mailman is not running
