Below are the changes for the current release. See the CHANGES file for changes in older releases. See the RELEASENOTES file for a summary of changes in each release. Version 3.0.9 (29 May 2016) =========================== 2016-05-24: mromberg [Python] Patch #612 - Add support for Python's implicit namespace packages. 2016-05-23: wsfulton [Ruby] Fix #602 - Error handling regression of opaque pointers introduced in swig-3.0.8 when C functions explicitly reset a pointer using 'DATA_PTR(self) = 0'. An ObjectPreviouslyDeleted error was incorrectly thrown when the pointer was used as a parameter. 2016-05-17: tamuratak [Ruby] Patch #651 - Correct overloaded function error message when function is using %newobject. 2016-05-17: aurelj [Ruby] Patch #582 - add support for docstring option in %module() 2016-05-14: wsfulton Fix #434 - Passing classes by value as parameters in director methods did not create a copy of the argument leading to invalid memory accesses if the object was used after the upcall into the target language. Passing arguments by value shouldn't give rise to these sorts of memory problems and so the objects are now copied and ownership of their lifetime is controlled by the target language. 2016-05-07: wsfulton Fix #611. Fix assertion handling defaultargs when using %extend for a template class and the extended methods contain default arguments. 2016-05-05: ejulian [Python] Patch #617. Fix operator/ wrappers. 2016-05-02: wsfulton Fix #669. Don't issue warning about ignoring base classes when the derived class is itself ignored. 2016-04-18: ianlancetaylor [Go] Fix use of goout typemap when calling base method by forcing the "type" attribute to the value we need. 2016-04-17: ianlancetaylor [Go] Fixes for Go 1.6: avoid returning Go pointers from directors that return string values; add a trailing 0 byte when treating Go string as C char*. 2016-04-06: smarchetto [Scilab] #552 Make Scilab runtime keep track of pointer types Instead of a Scilab pointer which has no type, SWIG Scilab maps a pointer to a structure tlist containing the pointer adress and its type. 2016-04-02: ahnolds [Python] Apply #598. Fix misleading error message when attempting to read a non-existent attribute. The previous cryptic error message: AttributeError: type object 'object' has no attribute '__getattr__' is now replaced with one mentioning the attribute name, eg: AttributeError: 'Foo' object has no attribute 'bar' 2016-04-02: derkuci [Python] Patch #610 to fix #607. Fix single arguments when using python -builtin -O with %feature("compactdefaultargs") 2016-03-31: wsfulton Fixes #594. Fix assertion for some languages when wrapping a C++11 enum class that is private in a class. Also don't wrap private enums for a few languages that attempted to do so. 2016-03-31: wsfulton [Java] unsigned long long marshalling improvements when a negative number is passed from Java to C. A cast to signed long long in the C layer will now result in the expected value. No change for positive numbers passed to C. Fixes #623. 2016-03-22: alexwarg [Lua] #398 Fix lua __getitem + inheritance The new handling of classes in Lua (not merging methods into the derived classes) breaks for classes that provide a __getitem function. The __getitem function prevents method calls to any method defined in a base class. This fix calls __getitem only if the member is not found using recursive lookup. 2016-03-18: ptomulik [Python] #563 Stop generating unnecessary _swigconstant helpers. 2016-03-16: richardbeare [R] #636 Add extra std::vector numeric types 2016-03-14: wsfulton [Java] Add std_array.i for C++11 std::array support. 2016-03-12: wsfulton [Java, C#, D] Fix static const char member variables wrappers with %javaconst(1) %csconst(1) or %dmanifestconst. This fixes the case when an integer is used as the initializer, such as: struct W { static const char w = 100; }; Fix generated code parsing enum values using char escape sequences when these values appear in the Java code (usually when using %javaconst(1)) such as: enum X { x1 = '\n', x2 = '\1' }; Similarly for static const member char variables such as: struct Y { static const char y = '\n'; } Likewise for D and %dmanifestconstant. For C# and %csconst(1), char values in C# are now hex escaped as C# doesn't support C octal escaping. 2016-03-11: wsfulton [Java C#] Add support for treating C++ base classes as Java interfaces instead of Java proxy classes. This enable some sort of support for multiple inheritance. The implementation is in swiginterface.i and provides additional macros (see Java.html for full documentation): %interface(CTYPE) %interface_impl(CTYPE) %interface_custom("PROXY", "INTERFACE", CTYPE) 2016-03-01: wsfulton Add rstrip encoder for use in %rename. This is like the strip encoder but strips the symbol's suffix instead of the prefix. The example below will rename SomeThingCls to SomeThing and AnotherThingCls to AnotherThing: %rename("%(rstrip:[Cls])s") ""; class SomeThingCls {}; struct AnotherThingCls {}; 2016-03-01: olly Fix isfinite() check to work with GCC6. Fixes https://github.com/swig/swig/issues/615 reported by jplesnik. 2016-02-17: olly [Python] Add missing keywords 'as' and 'with' to pythonkw.swg. 2016-02-07: kwwette [Octave] recognise various unary functions * Use __float__() for numeric conversions, e.g. when calling double() * Map various unary functions, e.g. abs() to __abs__(), see full list in section 32.3.10 of manual; only available in Octave 3.8.0 or later 2016-02-07: kwwette [Octave] export function swig_octave_prereq() for testing Octave version 2016-02-06: pjohangustavsson [C#] Fix duplicate symbol problems when linking the source generated from multiple SWIG modules into one shared library for the -namespace option. The namespace is now mangled into the global PInvoke function names. *** POTENTIAL INCOMPATIBILITY *** 2016-01-27: ahnolds [Python] Added support for differentiating between Python Bytes and Unicode objects using by defining SWIG_PYTHON_STRICT_BYTE_CHAR and SWIG_PYTHON_STRICT_UNICODE_WCHAR. 2016-01-27: steeve [Go] Ensure structs are properly packed between gc and GCC/clang. 2016-01-25: ahnolds [Python] Support the full Python test suite in -classic mode * Convert long/unsigned long/long long/unsigned long long to PyInt rather than PyLong when possible. Certain python functions like len() require a PyInt when operating on old-style classes. * Add support for static methods in classic mode, including support for pythonappend, pythonprepend, and docstrings. * Removing the use of __swig_getmethods__ for static member methods since they will always be found by the standard argument lookup * Fix a bug where the wrong type of exception was caught when checking for new-style class support 2016-01-23: ahnolds [Go] Enable support for the Go test-suite on OSX: * The linker on OSX requires that all symbols (even weak symbols) are defined at link time. Because the function _cgo_topofstack is only defined starting in Go version 1.4, we explicitly mark it as undefined for older versions of Go on OSX. * Avoid writing empty swigargs structs, since empty structs are not allowed in extern "C" blocks. 2016-01-12: olly [Javascript] Look for "nodejs" as well as "node", as it's packaged as the former on Debian. 2016-01-12: olly [Javascript] For v8 >= 4.3.0, use V8_MAJOR_VERSION. Fixes https://github.com/swig/swig/issues/561. 2016-01-10: ahnolds Improved size_t and ptrdiff_t typemaps to support large values on platforms where sizeof(size_t) > sizeof(unsigned long) and sizeof(ptrdiff_t) > sizeof(long).
