1. Moved RESTART_EXIT_CODE to constants so it can safely be used by
__main__.py.
2. Allowed __main__/main to return the desired exit code.
3. Forwarded the child processes exit code to the parent process to be
duplicated.
4. Added —debug flag to pass command to force Home Assistant to run in
only one process. A warning is printed to STDERR to indicate HASS is in
debug mode. Another is printed if HASS requests a restart in debug
mode. A restart request in debug mode will quit.
5. Added an argument to __main__/main/setup_and_run_hass to indicate
that it is running in the top process. This tells it to return the exit
code rather than exiting.
Implemented an OS and environment safe restart service. This works by
running Home Assistant in a child process. If the child process
terminates with an exit code > 0, HASS is restarted. SIGTERM and
KeyboardInterrupts to the parent process are forwarded to the child
process. KeyboardInterrupts will only be forwarded once. The second
KeyboardInterrupt will be handled by the parent.
Since the requirements only change when the software is updated,
this adds a command line switch to disable pip installs on
startup. The default behavior is maintained when the switch is
not specified. Skipping pip helps a lot with startup on older RPi
hardware.
Created three additional flags for the hass command:
-v - Toggle verbose log file output
—pid-file - Specify PID file path
—daemon - Launch as daemon (nix only)
The core now binds to SIGQUIT on nix systems to trigger a clean
shutdown.
Modified HTTP server to write logging messages through the logging
module.
Rewrote imports of exceptions to be from the exceptions module.
Made nmap scanner check for libnmap dependency without crashing.
Various flake8 and pylint updates.
Revised main to use frontend and demo strings rather than importing
their domains.
Removed submodule validation.
Moved local library mounting to the bootstrap module and out of core.
Added requirements_all.txt for all dependencies.
Made core dependencies looser.
Small updates to setup.py.
Cleaned up default config directory determination.
Made bootstrap creators for HA always set config directory.
Made bootstrap creators set the local library in the Python Path.
Moved all exceptions to their own file to make imports easier.
Moved default configuration directory be in the users’ profile.
Moved pip installs to be done to a lib folder in the config directory.
Reduced requirements.txt to only the barebones reqs.
