In A few observations on Python while I made my first steps into it, I mentioned the standard threading idiom in Python by wrapping the thread in a function. This has the drawback of having to catch and handle any exceptions in that function.
The higher level [WayBack] threading module has a [WayBack] Thread class with a [WayBack] run() method does not handle exceptions either.
For investigation of threading issues, it’s very convenient to know about the exceptions in a thread and their context.
So I’ve made a small base class that automagically logs any exceptions during a run:
import threading
from log import Log
class ExceptionLoggingThread(threading.Thread):
def __init__(self):
threading.Thread.__init__(self)
self.logger = Log().getLogger()
self.logger.debug("ExceptionLoggingThread().")
def run_logic(self):
self.logger.debug("Thread started.")
def run(self):
try:
self.run_logic()
except:
self.logger.exception('Exception in `run`')
raise
