New submission from Kevin Quick: The sentinel creates a named pipe, but the parent's end of the pipe is inherited by subsequently created children.
import multiprocessing,signal,sys def sproc(x): signal.pause() for each in range(int(sys.argv[1])): multiprocessing.Process(target=sproc, args=(each,)).start() signal.pause() Running the above on Linux with varying numbers of child processes (expressed as the argument to the above) and using techniques like "$ sudo ls /proc/NNNN/fd" it is possible to see an ever growing number of pipe connections for subsequent children. ---------- components: Library (Lib) messages: 263153 nosy: quick-b priority: normal severity: normal status: open title: multiprocessing sentinel resource leak type: resource usage versions: Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26732> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
