Martin Panter added the comment: I tend to agree with Serhiy about Eryksun’s patch. I understand it solves the current problem, and continues to protect against this scenario:
>>> b = bytearray(b"a") >>> c = ctypes.c_char.from_buffer(b) >>> b *= 1000 BufferError: Existing exports of data: object cannot be re-sized PyObject_AsWriteBuffer() and PyBuffer_Release() did get changed in 3.4, also by Issue 22896. Reviewing the history (mainly <https://hg.python.org/cpython/diff/1da9630e9b7f/Objects/abstract.c>), the only behaviour change I see is that it now clears view->obj to NULL, via the new PyBuffer_Release() call, before calling DECREF on the object. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25498> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
