Re: Proper way to delete/kill a logger?

2011-11-28 Thread cassiope
Thanks Chris and JM, I will explore how much work it's going to take to change the various scripts to _always_ starting the logger from main(). As further explanation - this code predates the logging module, and many of the functions/classes had an optional argument for the home- made logger - and

Proper way to delete/kill a logger?

2011-11-27 Thread cassiope
I've been trying to migrate some code to using the standard python logging classes/objects. And they seem quite capable of doing what I need them to do. Unfortunately there's a problem in my unit tests. It's fairly common to have to create quite a few entities in the course of a series of tests.

One more tidbit observed: my last note, that it works when using seteuid/setegid? Well - that only applies if the daemon is running under strace (!). It fails if started directly by root, or if the strace session has ended, leaving the main body of the daemon running in its normal headless manner.
