New submission from Antoine Pitrou <pit...@free.fr>: The select() and poll() loop implementations of Popen.communicate() call os.write() instead of the write() method on the stdin pipe, meaning any newline translation *and* unicode-to-bytes encoding step is skipped.
To use the write() method on the stdin pipe, we may have to set the file descriptor in non-blocking mode, especially given that _PIPE_BUF worth of characters can amount to more than _PIPE_BUF bytes on the underlying raw fd. See issue12591 for a simpler issue that was fixed. ---------- components: Library (Lib) messages: 141014 nosy: gregory.p.smith, pitrou priority: normal severity: normal stage: needs patch status: open title: "universal newlines" subprocess support broken with select- and poll-based communicate() type: behavior versions: Python 3.2, Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12623> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
