- Use native string for repr - Use rich comparison Removes the deprecated tp_compare in favor of tp_richcompare. Disparate types cannot be compared (except for == and !=), and True or False objects are returned explicitly. - Use Py_TYPE instead of ob_type This changed to conform to C aliasing rules, see http://legacy.python.org/dev/peps/pep-3123/ - Don't provide CObject creation function A PyCapsule based replacement would be possible, but might not be necessary considering the function is not used much. - Use new-style module initialization Build changes: - Use ABI flag in the lib name and pkg-config template - Use the SAMBA_CHECK_PYTHON macro for finding Python Signed-off-by: Petr Viktorin <pviktori@redhat.com> Reviewed-by: Andrew Bartlett <abartlet@samba.org> Reviewed-by: Jelmer Vernooij <jelmer@samba.org>
