Hi,This question is about issues with Twisted on OSX. It might be too twistd specific, the issue has popped up in other OSX 10.6 / python contexts. So I will give it a shot.Last year I struggled with crashes in a process using twisted.web, Quartz and OSX 10.6:Taking a fresh look (and some excellent help from a friend) I've managed to remove Quartz from the suspect list. The daemonising function in twisted calls fork(), but not exec(), similar to this bug:http://bugs.python.org/issue7895TheUSING_FORK_WITHOUT_EXEC_IS_NOT_SUPPORTED_BY_FILE_MANAGERflag shows up in crash reports.- Has anyone seen this specific problem with Twisted and 10.6?- What are the best practices for dealing with this issue?- Take it to the twisted list after all?- Any pointers welcome!The relevant code in twisted: _twistd_unix.py (in /twisted/scripts/). exec() - where? how?
Some code before the call to daemonize calls a Cocoa/Carbon API that triggers this. Which version of python are you using?
A script that displays the problem would be nice, that would make it a lot easier to hunt down the problem and find a solution.
