This patch causes PyBuffer_Release() to be called when the associated
buffer goes out of scope. I've been using it as follows:
...
Py_buffer_up buffer_up;
Py_buffer py_buf;
if (PyObject_CheckBuffer (obj)
&& PyObject_GetBuffer (obj, &py_buf, PyBUF_SIMPLE) == 0)
{
/* Got a buffer, py_buf, out of obj. Cause it to released
when it goes out of scope. */
buffer_up.reset (&py_buf);
}
...
This snippet of code was taken directly from an upcoming patch to
python-value.c.
gdb/ChangeLog:
* python/python-internal.h (Py_buffer_deleter): New struct.
(Py_buffer_up): New typedef.
