Hi, We're still using Python 2.5 so this question is about the pyprocessing module rather than the multiprocessing module, but I'm guessing the answer is the same.
I tend to use the Pool() object to create slave processes. If something goes wrong in the slave, an exception is raised there, which is then raised in the master or parent process, which is great. The problem is that if the master aborts due to the exception, it doesn't show the usual stack trace info for the slave, which would show (among other things) the line number the error occurred on. Instead, it shows the line in the master where work was sent to the slave (such as a call to pool.map()). I'm wondering what the recommended way is to write code that will reveal what went wrong in the slave. One obvious possibility is to have functions that are invoked in the slave incorporate their own exception handling that prints a stack trace. But I'd rather handle this issue in the master, rather than have to handle it in every function in the slave module that the master may invoke. Is there a way to do that? If not, what's the recommended approach? Thanks, Gary -- http://mail.python.org/mailman/listinfo/python-list
