eryksun added the comment: In Python 2, the closer for sys.stdout is _check_and_flush, which flushes the stream without closing the underlying FILE.
https://hg.python.org/cpython/file/ee879c0ffa11/Python/sysmodule.c#l1377 In Python 3, io.FileIO won't close the underlying file descriptor if closefd is False. >>> sys.stdout.buffer.raw.closefd False It isn't a writable attribute. It gets initialized to False by create_stdio (line 1034). https://hg.python.org/cpython/file/ab2c023a9432/Python/pythonrun.c#l1006 You'll can call os.close. Python 2: >>> sys.stdout.close(); os.close(1); sys.stdout = open('CONOUT$', 'w', buffering=0) >>> sys.stdout.fileno() 1 Python 3: >>> sys.stdout.close(); os.close(1); sys.stdout = open('CONOUT$', 'w') >>> sys.stdout.fileno() 1 ---------- components: -Windows nosy: +eryksun _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22673> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
