New submission from Serhiy Storchaka: In Python 2 when run the interpreter with the -u option the stdout and stderr streams are unbuffered. In Python 3 they become just line-buffered. This is because initially there was no way to create unbuffered text streams. But since Python 3.3 TextIOWrapper supports unbuffered output binary stream and accepts the write_through argument which switch off its own buffering.
Proposed patch makes the stdout and stderr streams truly unbuffered when run with the -u option. ---------- components: IO, Interpreter Core messages: 293960 nosy: benjamin.peterson, pitrou, serhiy.storchaka, stutzbach priority: normal severity: normal stage: patch review status: open title: Make stdout and stderr truly unbuffered when run with the -u option type: enhancement versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30404> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
