STINNER Victor added the comment: Attached patch modifies _pyio to mimick better the reference io module:
* Add IOBase._finalizing * IOBase.__del__() sets _finalizing to True * Add FileIO._dealloc_warn() * Remove FileIO.__del__() * FileIO.close(), _BufferedIOMixin.close() and TextIOWrapper.close() now calls _dealloc_warn() if _finalizing is true * Override closed() method in FileIO: needed because FileIO.close() now calls super().close() before logging the ResourceWarning, and the file is expected to see open in the warning * FileIO.close() now calls super().close() *before* closing the file descriptor I added hasattr(.., '_dealloc_warn') sanity checks because _dealloc_warn() are added to concrete classes, not to base classes. ---------- Added file: http://bugs.python.org/file42271/pyio_res_warn.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19829> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
