New submission from Hanno Boeck: I experience a segmentation fault with python 2.7 (both 2.7.5 and 2.7.6 tested on Ubuntu and Gentoo) when a large file is piped, the pipe is passed to os.popen and the process sends a SIGPIPE signal.
To create an easy to reproduce testcase grep can be used. See example attached. To test first create a dummy file containing zeros, around 1 megabyte is enough: for i in `seq 1 100000`; do echo "0123456789" >> dummy.txt; done Then pipe it to the script attached like this: cat dummy.txt | python2 minimal.py Result is a Segmentation fault. The same code doesn't segfault with python 3. ---------- components: Interpreter Core files: sigpipe_crash.py messages: 212897 nosy: hanno priority: normal severity: normal status: open title: segfailt with os.popen and SIGPIPE type: crash versions: Python 2.7 Added file: http://bugs.python.org/file34301/sigpipe_crash.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20866> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
