app_manager

Runs Python application in a fault-tolerant environment, continually rebooting after unexpected exceptions.

• Uses Python3 standard library packages only
• app_manager.py contains AppManager class

examples

installation

pip install app_manager

running your app in the AppManager is simple

import ApplicationClass
from app_manager import AppManager

app = ApplicationClass()
AppManager(app.run, run_limit = None) # set run_limit to positive integer to run application at most n times
''' Exceptions will be printed to the console '''

alternatively, you can pass in your app's logger so that exceptions appear in your log output

from application_package import ApplicationClass, logger
from app_manager import AppManager

app = ApplicationClass()
AppManager(app.run, logger = logger)
''' Exceptions will be printed to the console and logged with the supplied logger'''

each instance of AppManager runs in its own process, so multiple application components can be launched successively

from application_package import AppMainClass, main_logger
from background_package import BackgroundAppClass, bg_logger
from app_manager import AppManager

app = AppMainClass()
comp = BackgroundAppClass()
AppManager(app.run, logger = main_logger)
AppManager(comp.run, logger = bg_logger)
