Fixes#2101. There are 3 related changes made here:
1. Move the SWIG_globals() singleton into pyrun from pyint so it
is visible to SWIG_Python_DestroyModule(). The static globals
varlink has been extracted out of the function so that it can
be set to NULL in SWIG_Python_DestroyModule(), which fixes the
issue described in #2101. (Now when the second interpreter
starts up, the Swig_Globals_global pointer will be NULL, so it
knows it has to create a new one.)
2. Remove a Py_DECREF on the globals varlink. The decrement is now
performed by DestroyModule(), so there's no need to do it in
SWIG_init().
3. Fixed similar issue with SWIG_Python_TypeCache().
* commit '8245277ad3':
Remove test for unsupported complex or _Complex by itself
More C99 complex fixes, plus Python tests
Restore _Complex as standalone type
Small corrections for handling C99 _Complex
Properly handle C99 complex types even in C++ mode

* master-fix-vector-shared_ptr:
fixing memleak of shared_ptr objects in python with creating a [wrapped] vector<shared_ptr<Foo>> from a list of shared_ptr<Bar> where Bar is derived from Foo.
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.
