Starting and stopping Mailman
The Mailman daemon processes can be started and stopped from the command line.
All we care about is the master process; normally it starts a bunch of runners, but we don’t care about any of them, so write a test configuration file for the master that disables all the runners.
>>> from mailman.commands.tests.test_cli_control import make_config >>> make_config(cleanups)
>>> from mailman.testing.documentation import cli >>> command = cli('mailman.commands.cli_control.start')
Starting the daemons prints a useful message and starts the master watcher process in the background.
>>> command('mailman start') Starting Mailman's master runner Generating MTA alias maps
>>> from mailman.commands.tests.test_cli_control import find_master
The process exists, and its pid is available in a run time file.
>>> pid = find_master() >>> pid is not None True
You can also stop the master watcher process from the command line, which stops all the child processes too.
>>> command = cli('mailman.commands.cli_control.stop') >>> command('mailman stop') Shutting down Mailman's master runner
