The vector of pointers (just fixed) were not working correctly because the
descriptors returned from swig::type_info() were sometimes returning
zero. Zero should only be used for void * as the subsequent call to
SWIG_ConvertPtr will blindly cast the pointer without checking
descriptor.
std::vector<void *> does not work and will require further changes:
specializing traits_info<void *> to return 0 and traits_asptr<void *>.
I tried this and traits_asptr<void> also needs to be added in which
seems odd and requires further investigation...
Lib/python/pystdcommon.swg:
template <> struct traits_info<void *> {
static swig_type_info *type_info() {
static swig_type_info *info = 0;
}
};
Lib/std/std_common.i:
template <>
struct traits_asptr<void *> {
static int asptr(PyObject *obj, void ***val) {
void **p;
swig_type_info *descriptor = 0;
int res = SWIG_ConvertPtr(obj, (void **)&p, descriptor, 0);
if (SWIG_IsOK(res)) {
if (val) *val = p;
}
return res;
}
};
// this is needed, but am not sure this is expected
template <>
struct traits_asptr<void> {
static int asptr(PyObject *obj, void **val) {
void **p;
swig_type_info *descriptor = 0;
int res = SWIG_ConvertPtr(obj, (void **)&p, descriptor, 0);
if (SWIG_IsOK(res)) {
if (val) *val = p;
}
return res;
}
};
