Martin Panter added the comment: To create a memoryview with unlimited lifetime, I understand we need to nominate an “exporting object”, which becomes memoryview.obj. Using a bytes object here might be the simplest fix for just BufferedWriter.
However it looks like the buffer is shared with BufferedReader and others. To fix the analogous bug with BufferedReader, a bytearray might be better, because the user could see it being mutated when reading into the memoryview. I think bytearray might be okay for BufferedWriter too, as long as we prevent it being resized. The user would be able to alter the contents of the buffer, but I don’t see that as a problem. An alternative would be a new opaque object that doesn’t do much except have a reference count. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26720> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
