I will be the first to admit that I'm a little confused about logging, but I'm hoping someone can clarify what I think is a bug. Or it's just my misunderstanding of python. Or a misunderstanding about logging.
I don't seem to be able to get much utility from having multiple log handlers. And I'm curious about this line of code: https://github.com/apache/incubator-airflow/blob/master/airflow/www/views.py#L708 It feels like the code is trying to generate multiple possible handlers and use the one that successfully finds the log, but the above mentioned line is a bit of a fake generator. In the sense that it calls 'next' to grab the next value from the generator, but since the generator's scope is just the local function, it always just grabs the first handler. That is, other than the default it might as well just be coded as a list comprehension: handler = [handler for handler in logger.handlers if handler.name == task_log_reader][0] So my question is: is this attempting to use multiple log handlers to find the log and not doing so because of a bug using 'next', or am I misunderstanding what the log reader is trying to do?
