Enhance SWIGTYPE "out" typemaps to use std::move when copying
objects, thereby making use of move semantics when wrapping a function returning
by value if the returned type supports move semantics.
Wrapping functions that return move only types 'by value' now work out the box
without having to provide custom typemaps.
The implementation removed all casts in the "out" typemaps to allow the compiler to
appropriately choose calling a move constructor, where possible, otherwise a copy
constructor. The implementation alsoand required modifying SwigValueWrapper to
change a cast operator from:
SwigValueWrapper::operator T&() const;
to
#if __cplusplus >=201103L
SwigValueWrapper::operator T&&() const;
#else
SwigValueWrapper::operator T&() const;
#endif
This is not backwards compatible for C++11 and later when using the valuewrapper feature
if a cast is explicitly being made in user supplied "out" typemaps. Suggested change
in custom "out" typemaps for C++11 and later code:
1. Try remove the cast altogether to let the compiler use an appropriate implicit cast.
2. Change the cast, for example, from static_cast<X &> to static_cast<X &&>, using the
__cplusplus macro if all versions of C++ need to be supported.
Issue #999Closes#1044
More about the commit:
Added some missing "varout" typemaps for Ocaml which was falling back to
use "out" typemaps as they were missing.
Ruby std::set fix for SwigValueWrapper C++11 changes.
If a "docstring" feature is present it will still override a Doxygen comment.
If the "autodoc" feature is also present, the combined "autodoc" and "docstring"
will override the Doxygen comment. If no "docstring" is present then the
"autodoc" feature will not be generated when there is a Doxygen comment.
This way the "autodoc" feature can be specified and used to provide documentation
for 'missing' Doxygen comments.
Closes#1635
Move HAVE_CXX11 into makefiles so that running test-suite
from top level directory or in the language's test-suite directory
is consistent. For example, running 'make check-java-test-suite'
behaves the same as 'cd Examples/test-suite/java && make check'.

pyabc.i for abstract base classes now supports versions of Python
prior to 3.3 by using the collection module for these older versions.
Python-3.3 and later continue to use the collections.abc module.
The -py3 option no longer has any effect on the %pythonabc feature.
Types generated with and without -builtin are not compatible. Mixing
them in a common type list leads to crashes. Avoid this by using
different capsule names: "type_pointer_capsule" without -builtin and
"type_pointer_capsule_builtin" with.
See #1684
Both function annotations and variable annotations are turned on using the
"python:annotations" feature. Example:
%feature("python:annotations", "c");
struct V {
float val;
};
The generated code contains a variable annotation containing the C float type:
class V(object):
val: "float" = property(_example.V_val_get, _example.V_val_set)
...
Python 3.5 and earlier do not support variable annotations, so variable
annotations can be turned off with a "python:annotations:novar" feature flag.
Example turning on function annotations but not variable annotations globally:
%feature("python:annotations", "c");
%feature("python:annotations:novar");
or via the command line:
-features python:annotations=c,python:annotations:novar
Closes#1951
Testing is skipped where there is no support for it, that is,
using -builtin or -fastproxy. How to add this support in needs
determining, it's not clear how to do so.
Python function annotations containing C/C++ types are no longer
generated when using the -py3 option. Function annotations support
has been moved to a feature to provide finer grained control.
It can be turned on globally by adding:
%feature("python:annotations", "c");
or by using the command line argument:
-features python:annotations=c
The implementation is designed to be expandable to support different
annotations implementations. Future implementations could implement
something like the following for generating pure Python types:
%feature("python:annotations", "python");
or typing module types to conform to PEP-484:
%feature("python:annotations", "typing");
Closes#1561
Issue #735
- Improved documentation for using declarations.
- Issue new warning WARN_LANG_USING_NAME_DIFFERENT when there
is a conflict in the target language name to be used when
introducing a method via a using declaration. Previously
the method was silently ignored. Issue #1840. Issue #655.
Even in the case of just creating a `DerivedClass` this test says:
```
swig/python detected a memory leak of type 'DerivedClass *', no destructor found.
```
even though the destructor is defined in the base class.
Fix access to C++ static member functions using Python class
staticmethod syntax, such as Klass.memberfunction instead of
Klass_memberfunction, when using -fastproxy and -builtin in
combination with %callback.
The docstring containing the callback pointers were not being patched
during module initialisation.
Accept keyword arguments accessing C++ static member functions when
using -builtin and kwargs feature and Python class staticmethod syntax.
The missing keyword argument support was only when using the
class staticmethod syntax, not when using the flat static method
syntax.
Use Python class staticmethod syntax to access C++ static member functions,
such as Klass.memberfunction, instead of Klass_memberfunction.
