Your Environment

• Mypy version used: 0.812
• Mypy command-line flags: py.test-3 -v
• Mypy configuration options from mypy.ini (and other config files):
• Python version used: Python 3.9.1
• Operating system and version: Alpine Linux edge x86_64

Start with mypy/test/testdaemon.py::DaemonSuite::testDaemonStatusKillRestartRecheck and its case in test-data/unit/daemon.test. Reproduce the failure on Python 3.9 with Alpine Linux, then compare the expected and actual output for the dmypy status command. Done means the named unit test passes with the intended daemon status output.
