Armin Rigo added the comment: It used to be a consistently reliable behavior in Python 2 (and we made it so in PyPy too), provided of course that the process exits normally; but it no longer is in Python 3. Well I can see the reasons for not flushing files, if it's clearly documented somewhere as a change of behavior from Python 2.
However I'm complaining about the current behavior: files are flushed *most of the time*. That's a behavior that is clearly misleading, or so I would think. I'm rather sure that there are many small scripts and large programs out there relying on automatic flushing, and then one day they'll hit a case where the file is not flushed and get the worst kind of error: a file unexpectedly truncated at 99% of its length, in a way that cannot be reproduced by small examples. Feel free to close anyway as not-a-bug; I won't fight the Python 3 behavior, because Python 2 works as expected. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17852> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
