It's incompatible actually. https://github.com/python/cpython/blob/2.7/Include/object.h /* PyObject_HEAD defines the initial segment of every PyObject. */ #define PyObject_HEAD_INIT(type) \ _PyObject_EXTRA_INIT \ 1, type, https://github.com/python/cpython/blob/3.5/Include/object.h #define PyObject_HEAD_INIT(type) \ { _PyObject_EXTRA_INIT \ 1, type }, I noticed PyVarObject_HEAD_INIT is compatible, and simplified an extension I maintain. https://github.com/PyMySQL/mysqlclient-python/commit/2feb5ed6850a3905edf0333e0cd11ea6218f0f4f This small doc change helps people who writing Python 2's extension module now, and port it to Python 3 later. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29165> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
