Why did CPython add ResourceWarning when a file is not explicitly closed in the first place? That's because relying on reference counting to close files has been judged a bad programming practice by python-dev. The reasons for this judgement are along the lines of "because it breaks on every non-refcounted implementation". It's a good move from PyPy's point of view, and it is something that we implemented on PyPy2 too. Now the present discussion is about a similar case. Based on past experience, people are going to say first "it's not really important", then "it works fine in CPython", and finally in a few years python-dev is going to realize that it's maybe more important than what they originally thought. Nathaniel is trying to do the right thing from the start instead, so deserves a +1. Now *how* to do it exactly is a bit unclear, and largely involves language design questions (which pypy-dev is not the best place to address). A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev
