If python_append.i is modified to use:
__slots__ = []
instead of
__slots__ = ["this"]
then this additional error checking prevents a crash and shows a stack trace and error:
AttributeError: 'ForSlots' object has no attribute 'this'
Related to issue #1674
Don't attempt to use the class's __dict__ for setting 'this' when
a user has extended a class with:
__slots__ = ['this'].
Was segfaulting. Now we fall back to a simple PyObject_SetAttr if the
usual approach to setting 'this' in __dict__ does not work.
Closes#1673Closes#1674
Instead of silenty ignoring them, now a "TypeError: f() takes no keyword arguments"
exception is thrown if keyword arguments are used. Hence constructors and normal
methods/functions behave in the same way.
Closes issue #1595
Done in order to be C++17 compliant as it uses std::unexpected_handler
which was removed in C++17. This class was intended for director
exception handling but was never used by SWIG and was never documented.
Closes#1538
Give reference in container_owner a more unique name (back_reference).
Change back-reference 'ret' typemap to have a function name so that they
are less unwittingly be used elsewhere where not intended.
Note that they can be overridden by users if needed using:
%extend std::vector {
%typemap(ret)
value_type const& __getitem__,
value_type const& front,
value_type const& back
{ ... }
}
These override the SWIG supplied versions because the SWIG supplied
typemaps use non-const value_type&, but the methods use const, so the
above have a higher precedence in the typemap search algorithm.

Better name for container back-reference attribute
Python - Struct spec. for container owner
Python: Avoid container owner check for value types
Python: Init container owner attribute in thread-safe way
Python: Use PyObject_SetAttr instead of PyObject_GenericSetAttr for back-ref
Python: Cleanup container back ref
Python: Keep reference to owning container during element access
Use a struct with specialization to dispatch the container
owner reference function instead of a function. Avoids
possible future problems if overloading were introduced.
The typecheck typemaps succeed for non pointers (SWIGTYPE, SWIGTYPE&,
SWIGTYPE&&) when the equivalent to C NULL is passed from the target
language. This commit implements a fix for Python to not accept a Python
None for non-pointer types.
Issue #1202
Both the command line and %module options of the same name have been
removed. These were undocumented. The -outputtuple option returned a
Python tuple instead of a list, mostly typically in the OUTPUT
typemap implementations.
It unclear why a tuple instead of a list return type is needed and
hence this option has been removed as part of the simplification of
the SWIG Python command line options for SWIG 4.
Issue #1340.
