Re: Buffering of sys.stdout and sys.stderr in python3 (and documentation)

> sys.stderr = os.fdopen(sys.stderr.fileno(), 'w', 0) which unfortunately doesn't work! I guess will resort to python3 -u, although I don't want stdout to be unbuffered. -- https://mail.python.org/mailman/listinfo/python-list

Re: Buffering of sys.stdout and sys.stderr in python3 (and documentation)

It's surprising and broken that stderr should be buffered in python3. python3 calls setvbuf(3) on stderr at startup to achieve this chuckle-headed behavior. It makes stderr line buffered if on a terminal, and fully buffered if redirected to a log file. A fully buffered stderr is a very bad id
