Bug #1651235 : When a tuple was passed to a ctypes function call,
...
Python would crash instead of raising an error.
The crash was caused by a section of code that should have been
removed long ago, at that time ctypes had other ways to pass
parameters to function calls.

ctypes callback functions only support 'fundamental' result types.
...
Check this and raise an error when something else is used - before
this change ctypes would hang or crash when such a callback was
called. This is a partial fix for #1574584 .
Will backport to release25-maint.

Add asserts to check for 'impossible' NULL values, with comments.
...
In one place where I'n not 1000% sure about the non-NULL, raise
a RuntimeError for safety.
This should fix the klocwork issues that Neal sent me. If so,
it should be applied to the release25-maint branch also.

Remove the special casing of Py_None when converting the return value
...
of the Python part of a callback function to C. If it cannot be
converted, call PyErr_WriteUnraisable with the exception we got.
Before, arbitrary data has been passed to the calling C code in this
case.
(I'm not really sure the NEWS entry is understandable, but I cannot
find better words)

The __repr__ method of a NULL py_object does no longer raise an

Add commented assert statements to check that the result of

PyObject_stgdict() and PyType_stgdict() calls are non-NULL before
dereferencing the result. Hopefully this fixes what klocwork is
complaining about.
Fix a few other nits as well.

867200483b
Apply the patch #1532975 plus ideas from the patch #1533481 .
...
ctypes instances no longer have the internal and undocumented
'_as_parameter_' attribute which was used to adapt them to foreign
function calls; this mechanism is replaced by a function pointer in
the type's stgdict.
In the 'from_param' class methods, try the _as_parameter_ attribute if
other conversions are not possible.
This makes the documented _as_parameter_ mechanism work as intended.
Change the ctypes version number to 1.0.1.

When a ctypes C callback function is called, zero out the result
...
storage before converting the result to C data. See the comment in
the code for details.
Provide a better context for errors when the conversion of a callback
function's result cannot be converted.

Check the allocation of b_objects and return if there was a failure.
...
Also fix a few memory leaks in other failure scenarios.
It seems that if b_objects == Py_None, we will have an extra ref to
b_objects. Add XXX comment so hopefully someone documents why the
else isn't necessary or adds it in.

of bugs in that port. The most annoying ones were due to some subtle differences

some of libffi's unittests fail).
