Hey all,
How would I go about sharing a reassignment of excepthook, where that
assignment is made to a central function and could come from any of several
files?
I'm replacing a bunch of SQL jobs at work, and my boss said he doesn't care
which language I use. Naturally, Python it is. :)
All these jobs do different things, and run at different times and
different intervals. Some update files on our FTP server, some email the
previous day's shipping errors, some back up databases, and so on. The
setup I'm going to try first is one file per job, with utils.py and a
couple others shared between them all. That way, any job that needs to
email can just
import emailer
and every job can access configuration data:
import utils
utils.config["emails"]["alexHall"]
One thing that utils.py provides is logging:
import utils
logger = utils.ADLogger("Job Name")
The ADLogger object sets the level, the file name, the formatter, and so
on. It also has a function: logException(self, type, value, traceback).
This simply logs the exception, since ADLogger is a subclass of
logging.Logger.
Finally, my question. Say job1 and job2 run within a minute of each other,
but job1 takes a while to execute. Both jobs set their excepthook functions:
logger = utils.ADLogger("job1")
excepthook = logger.logException
logger = ADLogger("Job 2")
excepthook = logger.logExceptions
Now, Python is running two scripts which each have their excepthook set to
something different. What happens when both try to log an exception, or
even if one tries to while the other is running? Will this work how I hope,
or will there be confusion? Should I thread it somehow? I'd rather not have
a central manager, as that's one more thing that might fail; I plan to set
all the scripts up in Windows Task Scheduler. I can have a Python-based
manager if I need to, but it'd take me a while to finish that (I started
something similar months back and would have to finish and modify it). Am I
worrying over nothing, or will I need to do something to make sure each job
logs exceptions, and does it correctly, no matter who else is running at
the same time? Thanks.
