The buffering of stdout and/or stderr of your application probably changes if the application runs in a terminal (TTY) or if the output is redirected to a pipe (not a TTY). Set the setvbuf() function. You can try my hack to disable buffering using LD_PRELOAD: https://bitbucket.org/haypo/misc/src/4d133ea3e46550808305b093557ee51d2de2ac9f/misc/nobuffer.c?at=default ---------- nosy: +haypo _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22443> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
