Any simpler to just write:
return strdup (PyUnicode_AsUTF8 (str));
instead of using the temporary variable r?

Re: [PATCH libnbd 2/5] python: Allow Python callbacks to auto-retire by returning an integer.
...quot;;
This doesn't detect if the user returned a non-integer type (in which
case ret will be -1) - are we okay blindly returning -1 regardless of
whether the user returned actual -1 vs. if they returned some other
non-integer Python object that has no __int__ conversion? Or do we need
to use PyErr_Occurred() to distinguish between the two cases? This is
particularly interesting since we document that the C callback must
return -1 before any update to *err will take effect; do we want Python
to have to return -1 for that effect, or is it okay if python raises an
exception and we safely catch that as...

Or simpler (with error handling):
PyObject *v = PyObject_GetAttrString(m, "API_VERSION");
if (v == NULL)
return 1;
long value = PyLong_AsLong(v);
Py_DECREF(m);
return value;
On error -1 is returned and PyErr_Occurred() will return the exception type.

[PATCH nbdkit] python: Turn python exceptions into nbdkit errors
Much more annoying that it needs to be, but I have tested it and it
works on Python 2 & 3. Note this will not work on Python 3.0 - 3.2,
but I guess we don't care about those versions.

[hivex] Segfault for an integer value to node_set_value
Hi,
When an integer argument is passed as value, node_set_value
segfaults. Reproducer is at the end of this message
The backtrace points at hivex-py.c, function get_value. While obj
is non-NULL, `bytes = PyUnicode_AsUTF8String (obj);` returns NULL.
Kind regards,
Peter

[PATCH libnbd 0/5] WIP: python: Add test for doing asynch copy.
This doesn't yet work. However it does make me more convinced than
ever that we really need to sort out persistent buffer lifetimes in
the library (similar to what we did for closures).

[hivex] [PATCH 0/6] Python fixes for node_set_value
Hi,
This patch series is based on a prior patch[1], splitting off changes as
requested and incorporating feedback from Richard Jones. It introduces type
validation to avoid segmentation faults (instead, it reports an exception) and
fixes handling of the bytes type in Python 3.
Major changes since that series:
- Drop newly introduced support for integer types for DWORD/QWORDS
- Reject Unicode
