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.
Python fixed many APIs to use const char * instead of char * at around
Python 2.4. As we support 2.7 and later, we can now remove the non-const
string usage.
Types changed:
PyArg_ParseTuple
PyArg_ParseTupleAndKeywords
PyArg_UnpackTuple
PyDict_SetItemString
PyMethodDef
PyModuleDef
SWIG_Python_UnpackTuple
SWIG_Python_str_FromChar
SWIG_addvarlink
swig_const_info
This option, if used, has not had any effect on Python 3 code since commit a863d3 9 years ago.
I think we can assume that it is not needed for Python 3.
Running the examples and test-suite (Python 2) doesn't change the code
paths with and without -safecstrings because only SWIG_OLDOBJ and SWIG_NEWOBJ
are used in the typemaps and the following code is thus unaltered by -safecstrings
(which sets SWIG_PYTHON_SAFE_CSTRINGS):
%#if defined(SWIG_PYTHON_SAFE_CSTRINGS)
if (*alloc != SWIG_OLDOBJ)
%#else
if (*alloc == SWIG_NEWOBJ)
%#endif
{
*cptr = %new_copy_array(cstr, len + 1, char);
*alloc = SWIG_NEWOBJ;
printf("safe strings: %s\n", *cptr ? *cptr : "NULLSTRING");
} else {
*cptr = cstr;
*alloc = SWIG_OLDOBJ;
}
Note: nosafecstrings was also the default and -O didn't actually change this.
A custom implementation for Py_None was implemented in SWIG_Py_None().
This was used by default on Windows only. It isn't clear why this
was done just for Windows. Now Py_None is the real Py_None on all
operating systems.
What SWIG calls "modern" classes are supported by Python 2.3 and up
which means they're supported by all the Python versions we aim to
support in 4.0.0.

This is a cherry-pick and merge from the patch in #1261
Fix when using -builtin and wrapping std::map, std::set, std::unordered_map or
std::unordered_set to ensure __contains__ is called. This is a wrapper for the STL
container's find method. Without it, Python will do its own slower sequence search.
An error was not being set if an implicit conversion was attempted
calling an explicit constructor.
Fixes:
Fatal Python error: a function returned NULL without setting an error
SystemError: <built-in function new_A> returned NULL without setting an error
File "Examples/test-suite/python/implicittest.py", line 106 in __init_
- std::unordered_map compilation fix when just using std_unordered_map.i standalone
- std::unordered_multimap compilation fix when just using std_unordered_multimap.i standalone
- Add in the standalone unordered STL test cases
Closes#1319
The previous implementation failed with Python 3 and abstract base clases.
The new implementation replaces the Python 2 implementation using new.instancemethod with C API PyMethod_New to match the equivalent Python 3 implementation which uses PyInstanceMethod_New.
Closes#1310
When overloaded C++ methods are called, the fastdispatch mode sometimes
optimises out the generation of the typecheck typemap code, resulting in
the 'Possible C/C++ prototypes' information not being in the error message.
Now when a TypeError is thrown, the exception message is modified to contain the
'Possible C/C++ prototypes'.
See issue #1293
I've moved the initialization of statics a little earlier on - a little
safer as it is hard to follow exactly when some of these were being
used, such as SWIG_Py_None which sometimes replaces Py_None.
Fixes seg fault when passing a Python string, containing invalid utf-8 content,
to a wstring or wchar * parameter. A TypeError is thrown instead, eg:
%include <std_wstring.i>
void instring(const std::wstring& s);
instring(b"h\xe9llooo") # Python
Change the base classes in the pyabc.i file to use the
collections.abc module instead of collections due to the deprecation
of the classes in the collections module in Python 3.7.
Avoid casts between incompatible function types where possible (when
keyword args are in use, it is not possible to avoid such warnings as
they are inherent in the design of Python's C API in that particular
case). Fixes#1259.

- Remove python code from octave's std_basic_string.i
- Correctly return an error to fix error handling when using std::basic_string in
overloaded methods - issue #1171.
The directorin typemaps will now generate a temporary variable
(specified after the type), such as:
%typemap(directorin) MyType (MyType *temp) { ... use temp ... }
The shared_ptr director typemaps have been fixed for use in functions
that take more than one parameter.
Modify the Python and Ruby director shared_ptr typemaps to be language neutral.
Port the director modifications to other scripting languages that
have shared_ptr support - Octave, R and Scilab. Scilab shared_ptr
support is not fully working and needs work though.

[python] make SwigPyIteratorClosed_T and SwigPyIteratorOpen_T inherit from forward iterator classes.
[python] fix std unordered containers
This fragment needs to depend on StdTraits fragment as it specializes the
template struct traits<> defined there and it could happen that the struct was
not declared before being specialized, resulting in compilation errors in the
generated code.
It doesn't seem to need to depend on stddef.h inclusion, however, so replace
it with the correct dependency instead of keeping both.
"CID 11151 (#3-1 of 3): Using invalid iterator (INVALIDATE_ITERATOR)18.
increment_iterator: Incrementing iterator it though it is already past
the end of its container."
Coverity does not understand 'replace_count', so warns that we may go
past self->end() (or self->rend() I guess).
Fix Coverity issue reported for SWIG_Python_ConvertFunctionPtr:
"Execution cannot reach this statement: *ptr = vptr;"
Because if 'ty' is null, then desc becomes null and we return with
SWIG_ERROR. So 'ty' cannot be null at 'if (ty)'.
Fix Coverity issue reported for SWIG_Python_FixMethods:
"buffer_size: Calling strncpy with a source string whose length
(10 chars) is greater than or equal to the size argument (10)
will fail to null-terminate buff."
The issue is only reported for the "swig_ptr: " line, but for
consistency we replace both occurrences of strncpy with memcpy.
The way Python docstrings are indented has changed on master, so use the
standard inspect module in Python autodoc unit test to ignore the differences
in their indentation level between -builtin and non-builtin cases to make the
test still pass with the branch version, which avoids the use of different
(but almost identical) values in the test itself.
The metaclass (SwigPyObjectType) for SWIG objects was not defined in
a way that let importlib successfully import the Python wrappers.
The pickle module failed because it couldn't determine what module the
SWIG wrapped objects are in.
I've changed the definition of SwigPyObjectType using more normal
builtin type definitions. There are still some open questions:
- None of the builtin types, like swig_static_var_getset_descriptor and
SwigPyObject are added into any module. No call to PyModule_AddObject
is made, so isinstance cannot be used for any wrapped type, all of
which are derived from SwigPyObject.
Closes#808
The closure names used for builtin slots are mangled with their functype so
that overloaded C++ method names can be used for multiple slots.
For example:
%feature("python:slot", "mp_subscript", functype="binaryfunc") SimpleArray::__getitem__;
%feature("python:slot", "sq_item", functype="ssizeargfunc") SimpleArray::__getitem__(Py_ssize_t n);
will generate closures:
SWIGPY_SSIZEARGFUNC_CLOSURE(_wrap_SimpleArray___getitem__) /* defines _wrap_SimpleArray___getitem___ssizeargfunc_closure */
SWIGPY_BINARYFUNC_CLOSURE(_wrap_SimpleArray___getitem__) /* defines _wrap_SimpleArray___getitem___binaryfunc_closure */
Default hash is the underlying C/C++ pointer.
This matches up with testing for equivalence (Py_EQ in SwigPyObject_richcompare)
which compares the pointers.
If the wrong return type in the hash function was used, an error:
SystemError: error return without exception set
was raised
Add some tests for testing builtin slots
