New submission from STINNER Victor <victor.stin...@haypocalc.com>: subprocess.check_output() doesn't close explicitly pipes if an error occurs. See for example issue #12493 for an example of an error on .communicate().
Attached patch uses a context manager to ensure that all pipes are always closed and that the status is read to avoid zombies. Other subprocess functions should be fixed: - call() (will fix check_call) - getstatusoutput() (will fix getoutput): see patch attached to the issue #10197 to replace os.popen() by subprocess.Popen ---------- components: Library (Lib) files: subprocess_check_output.patch keywords: patch messages: 139812 nosy: haypo priority: normal severity: normal status: open title: subprocess: check_output() doesn't close pipes on error versions: Python 2.7, Python 3.2, Python 3.3 Added file: http://bugs.python.org/file22572/subprocess_check_output.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12494> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
