Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Mattias Engdegård (yorick) >Assigned to: Peter Åstrand (astrand) Summary: subprocess auto-reaps children Initial Comment: The subprocess module automatically reaps child processes, by maintaining a list of instances which is traversed each time a new Popen instance is created. Apparently this was originally intended to avoid large number of zombie processes to accrete in the system if the programmer is lazy and does not wait for them properly, but it can cause problems when the programmer wants greater control. In particular, it's not possible to use the pid from a subprocess.Popen instance, since it may already have disappeared. For instance, it makes it difficult to use os.wait() to wait for several child processes at the same time. The solution is simple: Add an option that disables the auto-reaper for a Popen instance. This makes everyone happy: existing code is unaffected, the programmer who wants to control her processes herself is allowed to do that, and the documentation is improved to help avoiding a nasty bug. A patch was posted to the patch tracker as number 1187312. I suggest it for inclusion into the next release. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1214859&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
