Version 4.0.0 (27 Apr 2019)
===========================
2019-04-24: vadz
#1517 Fix crash if "@return" Doxygen tag was used on a node without any return type.
2019-04-24: vadz
#1515 Fix parsing of enums with trailing comma when using -doxygen.
2019-04-19: ianlancetaylor
[Go] #1055 When generating Go code, make -cgo the default. Add new -no-cgo option
to disable the default.
2019-04-19: pbecherer
[Tcl] #1508 Fix Visual Studio 2015 and later compilation errors due to snprintf macro
definition.
2019-04-09: wsfulton
[C#] Fix FxCop warning CA2002 in SWIGPendingException - a lock on a reference of
type 'Type'.
2019-03-30: wsfulton
[Java, D] Add the parameters typemap attribute to the javadestruct,
javadestruct_derived, ddispose, ddispose_derived typemaps to mirror enhanced
flexibility in the csdisposing and csdisposing_derived (C#) typemaps. If provided
the contents are generated as the delete/dispose method's parameters declaration.
2019-03-30: wsfulton
[C#] #421 Fix FxCop warning CA1063 by implementing the recommended Dispose methods for
the IDisposable interface. Previously just the Dispose() method was generated.
Now the Dispose() and Dispose(bool disposing) methods are generated.
Changes are required if custom "csfinalize", "csdestruct" or "csdestruct_derived"
typemaps are being used. Details in #421 on Github. SWIG will error out if one of
the "csfinalize, "csdestruct" or "csdestruct_derived" typemaps are found. Example
error message:
foo.h:60: Error: A deprecated csfinalize typemap was found for Foo, please remove
it and replace all csdestruct, csdestruct_derived and csfinalize typemaps by the
csdispose, csdispose_derived, csdisposing and csdisposing_derived typemaps.

[C#] #1143 Add std_list.i for std::list support.
The C# std::list<T> wrappers are made to look and feel like a C#
System.Collections.Generic.LinkedList<> collection.
The IEnumerable<> interface is implemented in the proxy class.
The ICollection<> interface can also be implemented to provide enhanced functionality
whenever a C++ operator== is available. This is the case for when T is a
primitive type or a pointer. If T does define an operator==, then use the
SWIG_STD_LIST_ENHANCED macro to obtain this enhanced functionality, for example:
SWIG_STD_LIST_ENHANCED(SomeNamespace::Klass)
%template(ListKlass) std::list<SomeNamespace::Klass>;
2019-03-18: richardbeare
[R] #1328 Non-trivial enums are working now. The enum values are now obtained from
the C/C++ layer. const reference enums and C++11 enum classes are also now working.
2019-03-14: mochizk
[Javascript] #1500 Fix compilation errors due to deprecating V8 API in Node.js.
New V8 API is used if node.js >= v10.12, or if V8 >= v7.0.
2019-03-12: vadz
[C#] #1495 Add std_set.i for std::set support.
2019-03-11: dirteat,opoplawski
[Octave] Fix compilation errors in Octave 5.1.
error: format not a string literal and no format arguments [-Werror=format-security]
2019-02-28: wsfulton
[Java] std::vector improvements for types that do not have a default constructor.
The std::vector wrappers have been changed to work by default for elements that are
not default insertable, i.e. have no default constructor. This has been achieved by
not wrapping:
vector(size_type n);
Previously the above had to be ignored via %ignore.
If the above constructor is still required it can be added back in again via %extend:
%extend std::vector {
vector(size_type count) { return new std::vector< T >(count); }
}
Alternatively, the following wrapped constructor could be used as it provides near-enough
equivalent functionality:
vector(jint count, const value_type& value);
*** POTENTIAL INCOMPATIBILITY ***
2019-02-25: wsfulton
[Python] Fix compile errors wrapping overloaded functions/constructors where a vararg
function is declared after a non-vararg function.
2019-02-23: zphensley42
Use fully qualified name 'java.lang.Object' instead of 'Object' in generated code to
avoid clashes with wrapped C++ classes called 'Object'.
2019-02-23: gtbX
[Java] #1035 Add (const char *STRING, size_t LENGTH) typemaps in addition to the non-const
typemaps (char *STRING, size_t LENGTH) which does not attempt to write back to the const
string.
2019-02-22: tamuratak
[Ruby] #984 Add support for RTypedData introduced in Ruby 1.9.3.
2019-02-22: ZackerySpytz
#1483 Fix compilation failures when a director class has final methods.
2019-02-21: wsfulton
[Java] #1240 Suppress Java 9 deprecation warnings on finalize method.
2019-02-21: ZackerySpytz
#1480 Fix some rejections of valid floating-point literals.
2019-02-19: wsfulton
#1475 Fix regression parsing gcc preprocessor linemarkers in the form:
# linenum filename flags
2019-02-18: jakecobb
[Python] #945 #1234 Elements in std::vector memory access fix.
Accessing an element in a std::vector obtains a reference to the element via an
iterator pointing to the element in the container. If the vector is garbage collected,
the SWIG wrapper containing the pointer to the element becomes invalid. The fix is
to obtain a back-reference to the container by the wrapper to the element in the Python
layer to prevent the garbage collector from destroying the underlying container.
2019-02-17: wsfulton
Fix typemap matching to expand template parameters when the name contains
template parameters. In the %typemap below the type is T and the name is X<T>::make
and the name now expands correctly to X< int >::make
template<typename T> struct X {
%typemap(out) T X<T>::make "..."
T make();
};
%template(Xint) X<int>;
2019-02-16: wsfulton
Fix parser error containing multiple #define statements inside an enum.
The second #define fails to parse:
enum FooEnum {
ENUM1 = 0,
ENUM2 = 1,
#define MACRO_DEF1 "Hello"
#define MACRO_DEF2 "World!"
ENUM3 = 2,
ENUM4 = 3,
};
Bug mentioned at https://sourceforge.net/p/swig/patches/333/
2019-02-14: wsfulton
Add some missing copy constructors into STL containers.
2019-02-14: bkotzz
[Java] #1356 Add STL containers:
std::unordered_map
std::unordered_set
std::set
2019-02-14: bkotzz
[Java] #1356 std::map wrappers have been modified. Now the Java proxy class
extends java.util.AbstractMap. The std::map container looks and feels much like
a java.util.HashMap from Java.
A few members have changed their names. If the old method signatures are needed,

Python static method wrapper changes
- Static method wrappers were using the 'fastproxy' approach by default.
This is inconsistent with instance method wrappers. The fastproxy approach
is now turned off by default to be consistent with instance methods.
Static method wrappers can now also be controlled using the -fastproxy and
-olddefs options.
Example:
struct Klass {
static int statmethod(int a = 2);
};
generates by default:
class Klass(object):
...
@staticmethod
def statmethod(a=2):
return _example.Klass_statmethod(a)
instead of the following (which can be restored by using -fastproxy):
class Klass(object):
...
statmethod = staticmethod(_example.Klass_statmethod)
- Modernise wrappers for static methods to use decorator syntax - @staticmethod.
- Add missing runtime test for static class methods and using the actual class method.

[Python] #639 remove duplicate proxy method definitions for global function wrappers.
Global functions previously generated two definitions, eg:
def foo():
return _example.foo()
foo = _example.foo
The first definition is replaced by the second definition and so the second definition
is the one used when the method is actually called. Now just the first definition is
generated by default and if the -fastproxy command line option is used, just the second
definition is generated. The second definition is faster as it avoids the proxy Python
method as it calls the low-level C wrapper directly. Using both -fastproxy and -olddefs
command line options will restore the previously generated code as it will generate both
method definitions.
With this change, the wrappers for global C/C++ functions and C++ class methods now work
in the same way wrt to generating just a proxy method by default and control via
-fastproxy/-olddefs options.

[Python] #848 #1343 The module import logic has changed to stop obfuscating real ImportError

after an ImportError occurred and was done to support 'split modules'. A 'split module' is
a configuration where the pure Python module is a module within a Python package and the
low-level C/C++ module is a global Python module. Now a 'split module' configuration is
no longer supported by default. This configuration can be supported with a simple
customization, such as:
%module(package="mypackage", moduleimport="import $module") foo
or if using -builtin:
%module(package="mypackage", moduleimport="from $module import *") foo
instead of
%module(package="mypackage") foo

[Python] When using -builtin, the two step C-extension module import is now
one step and the wrapped API is only available once and not in an underlying
module attribute like it is without -builtin. To understand this, consider a
module named 'example' (using: %module example). The C-extension is compiled into
a Python module called '_example' and a pure Python module provides the actual
API from the module called 'example'. It was previously possible to additionally
access the API from the module attribute 'example._example'. The latter was an
implementation detail and is no longer available. It shouldn't have been used, but
if necessary it can be resurrected using the moduleimport attribute described in the
Python chapter of the documentation. If both modules are provided in a Python
package, try:
%module(moduleimport="from . import _example\nfrom ._example import *") example
or more generically:
%module(moduleimport="from . import $module\nfrom .$module import *") example
and if both are provided as global modules, try:
%module(moduleimport="import _example\nfrom _example import *") example

[Python] #1282 Make generated module runnable via python -m (PEP 366 conforming)
Previously any SWIG generated modules in a package would fail with an ImportError
when using 'python -m' for example 'python -m mypkg.mymodule'.
This fix also allows the SWIG generated module to be placed into a directory and
then renamed __init__.py to convert the module into a package again. This ability
stopped working in swig-3.0.9. However, only Python 2.7 or 3.3 and later work. If
Python 3.2 support is needed, use moduleimport in %module to customise the import
code.

[Python] #1261 #1340 Turn on many optimisation options by default and rationalise the
number of command line options.
There were an unnecessary number of command line options and many of these have now
been removed in a drive for simplification. Some were needed to support older versions
of Python (2.6 and earlier).
Many of the options could be turned on individually and when using -O. Previously -O
resulted in turning on a set of options:
-modern -fastdispatch -nosafecstrings -fvirtual -noproxydel
-fastproxy -fastinit -fastunpack -fastquery -modernargs -nobuildnone
Now -O results in turning on this reduced set:
-fastdispatch -fastproxy -fvirtual
The following options are now on by default, a deprecated warning is displayed if they
are used:
-fastinit Class initialisation code done in C/C++ rather than in Python code.
-fastquery Python dictionary used for lookup of types.
-fastunpack Faster unpacking of function arguments in C/C++ wrappers.
-modern Use Python 2.3 features such as object and property.
-modernargs Use Python 2.3 C APIs for unpacking arguments in tuples.
-noproxydel Stop generating a proxy __del__ method for backwards compatiblity.
-safecstrings No discernable difference
The following options have been removed altogether:
-aliasobj0
-buildnone
-classptr
-new_repr
-newrepr
-noaliasobj0
-nobuildnone
-nocastmode
-nodirvtable
-noextranative
-nofastinit

example.h:1: Error: Unknown SWIG preprocessor directive: if1 (if this is a block of
target language code, delimit it with %{ and %})
example.h:3: Error: Extraneous #endif.
The following is the correct syntax:
#if 1
#define ABC 123
#endif
The following of course also works:
#if(1)
#define ABC 123
#endif

[Java] director exception handling improvements.
When a director method throws an exception and it is caught by DirectorException
and passed back to Java using Swig::DirectorException::throwException, the Java
stack trace now contains the original source line that threw the exception.
Deprecate Swig::DirectorException::raiseJavaException, please replace usage with
Swig::DirectorException::throwException.
