Version 1.3.20 (In progress) ============================ 12/08/2003: mmatus (Marcelo Matus) The virtual method detections now properly treats the following cases: namespace foo { typedef int Int; } struct A {}; typedef A B; struct Foo { virtual ~Foo() {} virtual Foo* cloner() = 0; virtual int get_value() = 0; virtual A* get_class() = 0; virtual void just_do_it() = 0; }; struct Bar : Foo { Bar* cloner(); foo::Int get_value(); B* get_class(); void just_do_it(); }; All the Foo and Bar methods are virtual. A new attribute "virtual:type" record the base polymorphic type. In the previous cases we have: type : Bar virtual:type : Foo type : foo::Int virtual:type : int type : B virtual:type : A type : void virtual:type : void This attribute is useful in languages (java+directors) that could have problems redefining Bar* Bar::cloner(). If you never had code like the above, you will see no effects. But if you have some code like that, you will see some effects since some methods that before were not properly treated as virtual, will start to act like that. This could enlarge your director classes. 12/08/2003: mmatus (Marcelo Matus) The director protected member support (dirprot) is disabled by default. It can be enable by using '-dirprot' or by adding the option to the module declaration, like: %module(directors="1",dirprot="1") my_module This module option was added to properly compile the director_protected.i and director_nested.i examples. The feature has been tested with python[2.2,2.3] and ruby[1.6.7], both at compilation and runtime, and java[j2sdk1.4.1_01], but only at compilation (my java installation doesn't run any of the director examples, olds nor news). Please test for ocaml and java. The errors reported by William and Scott were fixed, except for a warning about SWIG_JavaThrowExecption() multiply defined. I can't reproduce this error with my examples. We will wait for Scott to send us a minimal case. 12/07/2003: mmatus (Marcelo Matus) The director protected member support has been completly moved out from python.cxx, and now resides in the common lang.cxx, emit.cxx and allocate.cxx files. This means it should work for all the other languages that currently support directors, ie, python, java, ocalm and ruby. The change has been tested with python (compilation+runtime) and java (just compilation). Please add runtime tests for the missing languages and test it. The '-nodirprot' option was moved to the principal main, and can be used from all the languages. 12/07/2003: cheetah (William Fulton) [Java] Fixed and improved error checking of STRING_OUT typemaps in various.i. 12/04/2003: mmatus (Marcelo Matus) - Now the virtual members with no explicit declarator are properly identified: struct A { virtual int f() = 0; }; struct B : A { int f(); }; Here, B::f() is virtual, and the director and the virtual elimination mechanism now recognize that. - [C#] This fix also fixes the problem where 'override' was not being used on any overridden virtual method, so for struct B above, this C# code is generated: public class B : A { ... public override int f() { ... } ... } - Initial support for protected virtual methods. They are now properly emitted when using with director (python only by now). %feature("director") A; struct A { protected: virtual int f1() = 0; }; %feature("director") B; struct B : A{ protected: int f1(); virtual f2(); }; This can be dissabled by using the '-nodirprot' option. - The feature 'nodirector' is working now at the top level, so, it must work for all the languages: %feature("director") A; %feature("nodirector") A::f2; struct A { virtual int f1(); virtual int f2(); }; in this case, only 'f1' is exported to the director class. - Added director support for const TYPE& arguments (python). 12/02/2003: cheetah (William Fulton) [Java] Fix for INOUT and OUTPUT typemaps in typemaps.i for when the JNI type is bigger than the C type. For example, unsigned long (32bits on most systems) is mapped to jlong (64bits). Returned value was incorrect. Bug reported by Brian Hawley. 12/02/2003: cheetah (William Fulton) [C# and Java] Better fix for entry dated 05/11/2003. Fixes the following typemaps: Java: javabase, javainterfaces, javaimports, javaclassmodifiers, javaptrconstructormodifiers, javafinalize, javagetcptr & javacode. C#: csbase, csinterfaces, csimports, csclassmodifiers, csptrconstructormodifiers, csfinalize, csgetcptr & cscode. It also fixes bug in using arrays of C structs with arrays_java.i as reported Scott Michel. 12/02/2003: beazley [Perl] Fixed [ 852119 ] recursive inheritance in output .pm, perl5. Reported by William Dowling. 12/02/2003: beazley [Tcl] Fixed [ 755382 ] calling func(const vector& p) evaluates p[0] in interp. The Tcl type checker was improperly handling the interpreter result when type violations were supposed to be ignored. Reported by Flaviu Popp-Nowak. 11/30/2003: cheetah (William Fulton) Fixed [ 545058 ] configure's --with-tclincl has no effect 11/30/2003: cheetah (William Fulton) [Java] Fixed [ 766409 ] missing symbol SWIG_JavaThrowException during module load SWIGs internal functions are all static as there is no need for different SWIG generated modules to share any code at runtime. 11/30/2003: beazley [Tcl] Added support for C++ pointers to members. 11/28/2003: cheetah (William Fulton) Fixed [ 848335 ] Directors: #include wrapper .h file - was incorrectly adding a directory to the generated #include "foo_wrap.h" statement in some situations. 11/28/2003: cheetah (William Fulton) [Java] Fixed [ 849064 ] JAVA : Access modifier for derived class wrong. The delete() method is always public now. It used to be protected whenever a destructor was non public. An UnsupportedOperationException runtime exception is thrown instead of making delete() protected now. 11/28/2003: beazley [Perl5] Added support for C++ pointers to members. 11/28/2003: beazley Fixed [ 850151 ] PYVERSION with python2.3 in configure of SWIG 1.3.19 (Maybe). 11/28/2003: beazley Fixed [ 850666 ] #include extra line added. This should fix some problems with getting correct line numbers on error messages. 11/26/2003: beazley Fixed another one of Marcelo's evil template bugs (infinite recursion). [ 849504 ] template and typedef -> inf. recursion. 11/26/2003: beazley Fixed parsing problem with declarations like this: int *x = &somearray[0]; 11/25/2003: beazley Fixed [ 756552 ] missing default argument class scope with "|". This is really only a band-aid fix for use of class-enums in expressions. For example: class A { public: enum Flag { flag1 = 0x1, flag2 = 0x2 }; void foo(int x = flag1 | flag2); }; Note: there are still some (more subtle) cases that are broken, but hard to fix due to an issue with template expansion. Will address later. Reported by Dmitry Mironov. 11/25/2003: beazley Incorporated [ 840878 ] support for %inline { ... } (PATCH). This adds support for the following: %inline { ... some code ... } The difference between this and %inline %{ ... %} is that the enclosed text is processed by the SWIG preprocessor. This allows special macros and other processing to be used in conjunction with %inline. Contributed by Salvador Fandino Garcia. 11/25/2003: beazley Fixed [ 836903 ] C++ inconsistency (with void arguments). SWIG was having difficulty with f() vs f(void) in C++ programs. For instance: class A { public: virtual void f(void) = 0; }; class B { public: virtual void f(); // Not matched to f(void) correctly }; The parser now normalizes all declarations of the form f(void) in C++ classes to f(). This should fix a variety of subtle problems with inheritance, optimizations, overloading, etc. Problem reported by Partho Bhowmick. 11/25/2003: beazley [Perl5] Incorporated [ 841074 ] better croaking (PATCH). This fixes some problems with strings and provides some new error functions. Contributed by Salvador Fandino Garcia. 11/25/2003: beazley Fixed [ 791835 ] Default argument with cast: txt = (char *)"txt" syntax Error. The parser should now accept things like this: void foo(char *s = (char *) "Hello"); Problem reported by Claudius Schnorr. 11/24/2003: beazley [Tcl] Fixed problem with cross module linking. Previously modules referred to base classes through a global variable. Now, the module looks up base classes through the type system itself---avoiding the need to link to a global like before. Caveat: modules with base classes must be loaded before modules with derived classes. 11/24/2003: mkoeppe (Matthias Koeppe) [Guile] In -scm mode, use () to represent null pointers, as it is done in -gh mode. 11/23/2003: mkoeppe (Matthias Koeppe) Add a generated script "preinst-swig", which can be used to invoke SWIG before it has been installed. It arranges that the runtime libraries from the source directory are used. 11/23/2003: mkoeppe (Matthias Koeppe) [Guile] In -gh mode, don't forget to call SWIG_Guile_Init. Add a SWIG_contract_assert macro. 11/23/2003: mkoeppe (Matthias Koeppe) [MzScheme] Update the configure check for the dynext object to work with MzScheme 205. 11/20/2003: mmatus Fixed the include/import error reported by Kerim Borchaev, where two files with names like 'dir1/hello.i' 'dir2/hello.i' can not be include at the same time. Swig was including just the first one, assuming the second one was not a different one, since it was checking/keeping just the basename 'hello.i'. 11/19/2003: beazley Changes to the SWIG runtime library support. - The -c command line option has been renamed to -noruntime - New command line option: -runtime. When supplied, this inserts the symbol SWIG_GLOBAL into the wrapper code. This, in turn, makes all of the runtime support functions globally visible. - New library file: swigrun.i. Used to create modules for runtime library (if needed). 11/18/2003: cheetah (William Fulton) 'make srcrpm' rpmbuild fix - patch from Joe Cooper 11/18/2003: mkoeppe (Matthias Koeppe) [Guile] Change meaning of configure option --with-guile to the name of the Guile executable. The new option --with-guile-prefix can be used to specify the tree where Guile is installed. (However, usually it suffices to use the single option --with-guile-config.) When running the run tests test-suite, make sure to use the version of Guile that SWIG was configured for. 11/17/2003: mkoeppe (Matthias Koeppe) [Guile] Improvements to object-ownership management in "-scm" mode. (They do not apply to the default "-gh" mode.) * Renamed the smob type that indicates that the object can be garbage collected from "collected swig" to "collectable swig", which is more precise. * Export the destructor functions again. It is now allowed to explicitly call destructors, even for garbage-collected pointer objects. A pointer object that has been passed to a destructor is marked in a special way using a new smob type, "destroyed swig". (This helps avoid nasty memory bugs, where references to dead C objects are still held in Scheme. Moreover, the garbage collector will not try to free a destroyed object once more.) * Destructor-like functions can also mark their arguments as destroyed by applying the typemap SWIGTYPE *DESTROYED. (It calls the function SWIG_Guile_MarkPointerDestroyed.) * Functions that "consume" their objects (or that "own" them after the call) can mark their arguments as not garbage collectable. This can be done by applying the typemap SWIGTYPE *CONSUMED. (It calls the function SWIG_Guile_MarkPointerNoncollectable.) * The macro TYPEMAP_POINTER_INPUT_OUTPUT from library pointer-in-out.i creates additional typemaps PTRTYPE *INPUT_CONSUMED, PTRTYPE *INPUT_DESTROYED. They mark the passed pointer object likewise. The typemap PTRTYPE *OUTPUT creates a garbage-collectable pointer object, like %newobject does for a returned pointer. Use the new typemap PTRTYPE *OUTPUT_NONCOLLECTABLE to create a pointer object that will not be garbage collected. 11/17/2003: mkoeppe (Matthias Koeppe) [Guile] Handle $input in "freearg" typemaps. Never qualify GOOPS slot names with the class name. Handle optional arguments properly in the GOOPS methods. 11/16/2003: cheetah (William Fulton) Fixes for installation to work with the upcoming Automake-1.8. mkinstalldirs was being used by a non-Automake makefile. mkinstalldirs is being phased out and so was not being created by Automake. install-sh used instead. 11/16/2003: cheetah (William Fulton) [Java] Numerous director improvements, tweaks and bug fixes since the initial implementation have been contributed by Scott Michel. 11/12/2003: beazley [Python] When %feature("shadow") is used to add code to shadow classes, the special variable $action expands to the name of the underlying wrapper function that would have been called normally. 11/12/2003: beazley [Python] When generating proxy class code, SWIG emits a few default methods for __repr__() and other Python special methods. Some of these methods are emitted after all of the contents of a class. However, this makes it hard to override the methods using %pythoncode and some other directives that allow code to be inserted into a class. These special methods are now emitted into the code *before* all of the other methods. Suggested by Eric Jones. 11/11/2003: beazley Preprocessor enhancement. For include statements like this: %include "foo/bar.i" the directory "foo" is now added to the search path while processing the contents of bar.i. Thus, if bar.i includes other files in the same directory, they will be found. Previously, you would have to add additional directories using -I to make this work correctly. Note: the C preprocessor seems to behave in an identical manner on many (most? all?) systems. Suggested by Kerim Borchaev. 11/11/2003: beazley Configuration changes to make SWIG work on Mac OSX 10.3.x (Panther). Tested with Python, Tcl, Perl, and Ruby---all of which seem to work. 11/08/2003: cheetah (William Fulton) [Java] Fixed the typemaps in various.i which were mostly broken. char **STRING_IN and char **STRING_RET typemaps replaced with STRING_ARRAY. float *FLOAT_ARRAY_RETURN typemap removed. 11/08/2003: beazley [Tcl] Tcl module now emits a safe module initialization function by default. It can be removed by running 'swig -nosafe'. 11/04/2003: mkoeppe (Matthias Koeppe) [Guile] Only use the SCM_ API when the function `scm_slot_exists_p' exists (needed for GOOPS support). This function was renamed during the Guile 1.5 series from `scm_slots_exists_p'. Report the right runtime library when invoked with -scm -ldflags. 11/03/2003: mkoeppe (Matthias Koeppe) [Chicken] Fix #782052. The --with-chickencfg configure option (and others) were not accepted. 11/02/2003: mkoeppe (Matthias Koeppe) [Guile] Merge new set of GOOPS changes by John Lenz. GOOPS objects are now manipulated directly by the C code. Some fixes to typemap-GOOPS interaction. 11/02/2003: mkoeppe (Matthias Koeppe) [Guile] Remove the file argument to -scmstub and -goops. The Scheme files are now always called MODULE.scm or MODULE-primitive.scm, where MODULE is the module name and "primitive" can be changed by the -primsuffix option. The Scheme files are now placed in the directory given by the -outdir option, or the current directory. (Patch by John Lenz, slightly modified.) *** INCOMPATIBILITY [Guile] *** 11/02/2003: mkoeppe (Matthias Koeppe) Unify the pointer-conversion runtime API. The standard functions are: * SWIG_NewPointerObj (POINTER, TYPE, FLAGS) -- Create an scripting object that represents a typed pointer. FLAGS are language specific. * SWIG_ConvertPtr (INPUT, RESULT, TYPE, FLAGS) -- Get a pointer from the scripting object INPUT and store it in the place RESULT. When a type mismatch occurs, return nonzero. * SWIG_MustGetPtr (INPUT, TYPE, ARGNUM, FLAGS) -- Get a pointer from the scripting object INPUT and return it. When a type mismatch occurs, throw an exception. If ARGNUM > 0, report it as the argument number that has the type mismatch. [Guile]: No changes. [MzScheme]: No changes. [Perl]: Add the function SWIG_NewPointerObj. The function SWIG_MakePtr is kept. The function SWIG_MustGetPtr is currently not supported. [Python]: Add the function SWIG_MustGetPtr. [Ruby]: Add the function SWIG_MustGetPtr. [Tcl]: Remove the "interp" argument of SWIG_NewInstanceObj, SWIG_ConvertPtr, SWIG_ConvertPacked, and SWIG_ConvertPtrFromString. The function SWIG_MustGetPtr is currently not supported. No changes to Pike because its pointer conversion code did not look complete. No changes to PHP4, because I did not understand its runtime code. No changes to Chicken because major changes are expected soon anyway. No changes to Java, OCaml, C# because they do not seem to have a pointer-conversion runtime API. *** INCOMPATIBILITY [Tcl] *** 11/02/2003: mkoeppe (Matthias Koeppe) [Perl5, PHP4, Pike, Python, Ruby, Tcl]: Use the preprocessor to rename external functions of the SWIG runtime API to follow the naming convention SWIG__. This should allow linking more than one interpreter into a program. 10/31/2003: cheetah (William Fulton) [C#] Fix since introducing the exception and std::string delegates. The fix overcomes linker errors when using more than one SWIG module. Problem reported by Andreas Schörk. 10/31/2003: beazley Incorporated patch: [ 823302 ] Incr Tcl support. Contributed by Alexey Dyachenko. Note: needs documentation. 10/31/2003: beazley Incorporated patch: [ 829325 ] new Python Module options and features. Robin Dunn writes: This patch makes a number of changes to the SWIG python module. 1. Add -apply option, and change the default code output to use the foo(*args, **kw) calling syntax instead of using apply(). If the -apply option is given then code is generated as before. This is very similar to Patch #737281 but the new -modern option makes the second half of that patch unnecessary so it is not included here. 2. Add -new_repr option. This is the same as my Patch #797002 which I will mark as closed since it is no longer needed. When this new option is used then the __repr__ methods that are generated for proxy classes will be more informative and give details about the python class and the C++ class. 3. Add %feature("addtofunc"). It allows you to insert one or more lines of code inside the shadow method or function that is already generated, instead of replacing the whole thing like %feature("shadow") does. For __init__ it goes at the end, for __del__ it goes at the begining and for all others the code generated is expanded out to be like def Bar(*args, **kwargs): val = _module.Foo_Bar(*args, **kwargs) return val and the "addtofunc" code is inserted just before the return statement. If the feature is not used for a particular method or function then the shorter code is generated just like before. 4. A little bit of refactoring to make implementing addtofunc a little easier. 5. Added a -modern command-line flag that will cause SWIG to omit the cruft in the proxy modules that allows it to work with versions of Python prior to 2.2. The result is a simpler, cleaner and faster python proxy module, but one that requires Python 2.2 or greater. 10/31/2003: beazley Incorporated patch: [ 829319 ] XML module tweaks. This adds a new command line option -xmllite that greatly reduces the amount of emitted XML code by eliminating some fields mostly used in SWIG's internal processing. Contributed by Robin Dunn. 10/31/2003: beazley Incorporated patch: [ 829317 ] Adds DohSplitLines function. Contributed by Robin Dunn. 10/29/2003: beazley Fixed [ 827907 ] argout objects not being wrapped properly (PATH). Patch contributed by Salvador Fandiño García. 10/29/2003: beazley Fixed [ 826996 ] perl type checking ignores perl subclasses. This enhancement makes it so wrapped classes and structs can be subclassed in Perl and used normally. Patch contributed by Salvador Fandiño García. 10/16/2003: cheetah (William Fulton) [C#] IntPtr marshalled with a void* instead of int in C function declarations. The casts thus look more conventional, for example: // old DllExport double SWIGSTDCALL CSharp_get_Shape_x(int jarg1) { ... Shape *arg1 = (Shape *) 0 ; arg1 = *(Shape **)&jarg1; ... } // new DllExport double SWIGSTDCALL CSharp_get_Shape_x(void * jarg1) { ... Shape *arg1 = (Shape *) 0 ; arg1 = (Shape *)jarg1; ... } 10/14/2003: beazley Fixed a subtle problem with overloaded methods and smart pointers. If a class has overloaded methods like this: class Foo { public: int bar(int x); static int bar(int x, int y); }; and the class is used as a smart pointer: class FooPtr { public: Foo *operator->(); }; The SWIG would try to expose the static member Foo::bar through FooPtr---resulting bogus wrapper code and a compiler error. Due to the way in which overloading is handled, it is extremely difficult to eliminate the static method in this case. Therefore, it is still exposed. However, the generated code now compiles and works. 10/05/2003: mkoeppe (Matthias Koeppe) [Guile, MzScheme, Chicken]: Remove symbol clashes between the runtime libraries by renaming all extern common.swg functions with the preprocessor. 10/05/2003: mkoeppe (Matthias Koeppe) [Guile] Added basic GOOPS support, contributed by John Lenz. See the documentation for details. *** NEW FEATURE *** 10/04/2003: mkoeppe (Matthias Koeppe) [Guile] New option, -only-setters, which disables traditional getter and setter procedures for structure slots. 10/03/2003: mkoeppe (Matthias Koeppe) [Guile] Added run test for reference_global_vars by John Lenz. 09/30/2003: beazley Partial solution to [ 792180 ] C++ smart-pointer/namespace mixup revisited. The problem is not easy to fix (at least it doesn't seem so), but is related to the instantiation of qualified templates inside of other namespaces. SWIG now generates an error message in this case rather than generating broken wrappers. 09/30/2003: beazley Fixed [ 800012 ] ENTER macro from CORE/scope.h clashes with libc search.h. Reported by Britton Leo Kerin. 09/30/2003: beazley Fixed [ 811518 ] Casting ints to doubles (w/ solution?) Addresses a problem with overloading in the Perl module. Reported by Gerald Dalley. 09/28/2003: mkoeppe [Guile with -scm option] Fix typo in generated code for procedures-with-setters. Reported by John Lenz. 09/26/2003: beazley Fixed [ 812528 ] externs not correct when throw is in signature. Reported by Joseph Winston. 09/23/2003: cheetah (William Fulton) SWIG was generating a number of symbols that didn't comply with the ISO C/C++ standard, in particular ISO/IEC 14882:1998(E) 17.4.3.1.2 where double underscores are forbidden as well as symbols starting with an underscore followed by an upper case letter. Most of these have been rooted out. See new section added to internals.html development manual 'Symbol Naming Guidelines for Generated C/C++ Code'. 09/23/2003: cheetah (William Fulton) Director typemap name changes: inv => directorin outv => directorout argoutv => directorargout *** POTENTIAL INCOMPATIBILITY *** 09/19/2003: mrose (Mark Rose) [Python] Director constructors now default to __disown = 0, which is the intended behavior and fixes the director_finalizer test case under python. 09/12/2003: cheetah (William Fulton) [C#] - Typemaps added for std::string and const std::string &. - New delegate for creating a C# string given a char *. It can be used by calling SWIG_csharp_string_callback as shown in the std::string 'out' typemap. Useful if the return type is mapped to a C# string and the calling function is responsible for cleaning up memory as the C# garbage collector doesn't free the memory created in C/C++ and then returned as a C# string. - The exception delegates have moved into an inner class in the intermediate class, thereby freeing up the static constructor. 09/11/2003: beazley (Internals) Major refactoring of iteration over lists and hashes. The DOH library now uses iterators. They work like this: List *l = (some list); Iterator i; for (i = First(l); i.item; i = Next(i)) { // i.item contains the actual list item. // i.item is NULL at end of list ... } Hash *h = (some hash); Iterator j; for (j = First(h); j.item; j = Next(j)) { // j.item contains hash table item // j.key contains hash table key // Both j.item and j.key are NULL at end ... } The old iteration functions Firstitem(), Nextitem(), Firstkey(), and Nextkey() are gone. The new iterators are simpler, result in better memory use, and may be faster. Also, there are no longer any problems iterating over the same list/hash in multiple places at the same time. For example, this is fine: Iterator i,j; for (i = First(l); i.item; i = Next(i)) { for (j = First(l); j.item; j = Next(j)) { ... } } (This never worked in previous versions). *** POTENTIAL INCOMPATIBILITY ***. This will probably break third party extensions to SWIG (or give them further encouragement to join the SWIG CVS-tree :-). 09/10/2003: mkoeppe (Matthias Koeppe) [Guile] Fix memory leaks in the "list-vector.i" typemaps. 09/09/2003: mkoeppe (Matthias Koeppe) [Chicken] Use C_mk_bool rather than C_mkbool. This fixes the wrapping of boolean values for Chicken 1.10 and newer. Reported by Dave / Felix Winkelmann . 09/05/2003: cheetah (William Fulton) [Java] Directors implemented for Java. In summary this is a big new feature which supports upcalls from C++ to Java. Code is generated to support C++ callbacks to call into Java and true polymorphic behaviour for Java classes derived from C++ classes. See java.html for details. Contributed by Scott Michel. 09/05/2003: Tiger Created contract example directory at /SWIG/Examples/contract Added simple contract examples (simple_c & simple_cxx) Modified contract module's output format *** NEW FEATURE *** 09/01/2003: cheetah (William Fulton) Test-suite build improvements: - Multiple build directories working for the test suite, so it is now possible to run configure in multiple subdirectories and run the test suite in each of these sub directories. - 'make distclean' fixed so it doesn't bomb out on the Examples directory when using multiple subdiretory builds. Required the following directories to be moved: Examples/GIFPlot/Perl -> Examples/GIFPlot/Perl5 Examples/GIFPlot/Php -> Examples/GIFPlot/Php4 These new directories used to be symbolic links to the old directory. Also the Examples/test-suite/Perl symbolic link has been removed. - Running the test-suite, other than from the root directory, say in Examples/test-suite/python will now display all the code being executed. - The following 3 C# compilers are detected during configure and work with the test-suite: Mono, Portable.NET and Microsoft. 09/01/2003: Tiger Added inheritance support for design by contract feature. 09/01/2003: beazley Fixed [ 794914 ] Wrong types in template specialization. SWIG was not handling arguments correctly in template partial specialization. For example, template class Foo { public: T *blah(); }; %template(FooInt) Foo; in this class, the return type of blah was set to 'int **', but it should really be 'int *'. This has been fixed, but it will affect all prior uses of partial specialization. 09/01/2003: beazley Fixed [ 786394 ] Patch for generated perl code does not compile under RedHat9. Reported by Scott Finneran. 09/01/2003: beazley Fixed [ 791579 ] (unsigned) long long handled incorrectly (Tcl). This was an error in the Tcl typemaps.i file. Reported by Kjell Wooding. 09/01/2003: beazley Fixed [ 797573 ] no way to rename classes coming from C structures. This problem relates to renaming of anonymous structures with a typedef. For example: %rename(Bar) Foo; typedef struct { ... } Foo; Reported by Britton Leo Kerin. 09/01/2003: beazley Fixed [ 797576 ] -help seems to imply that only tcl-specific options exist. Added a comment to alert user to other options. Reported by Britton Leo Kerin. 09/01/2003: beazley Fixed [ 798205 ] Segfault in SWIG_ConvertPtr. Reported by Prabhu Ramachandran. 08/30/2003: mrose (Mark Rose) Modified the director typemaps in python/std_complex.i to use the new-style macro and conversion functions, which eliminated some redundant code. Fixed a few bugs in these typemaps as well, although more testing is needed. 08/29/2003: mrose (Mark Rose) Completed initial support for wrapping abstract classes with directors. Constructor wrappers will be generated for abstract classes that have directors, and instances of the director classes will be created regardless of whether the proxy class has been subclassed in the target language. No checks are made during construction to ensure that all pure virtual methods are implemented in the target language. Instead, calls to unimplemented methods will throw SWIG_DIRECTOR_PURE_VIRTUAL_EXCEPTION exceptions in C++. Integrated Prabhu Ramachandran's typemap patches, which provide director typemap support for enums and std::size_t, and fix a couple bugs in the director std::vector<> typemaps. 08/29/2003: cheetah (William Fulton) [C#] Implemented exception handling for throwing C# exceptions from C/C++ code. A few delegate functions are available for calling which then throw the C# exception. Use the SWIG_CSharpThrowException function from C/C++ typemaps. See the generated wrapper code or csharphead.swg for all available exceptions. Example: SWIG_CSharpThrowException(SWIG_CSharpException, "exception description"); The 'throws' typemaps are also now implemented, so code is automatically generated to convert any C++ exception into a C# System.Exception when the C++ method declares an exception specification such as: int foo() throw(Bar); Also any parameters that are references to a C++ class or a class passed by value and are passed as a C# null will now throw a C# NullReferenceException. 08/29/2003: cheetah (William Fulton) [C#] Fix to match the calling convention of all pinvoke methods so that they match the calling convention used by default in the C# 'static extern' declarations (__stdcall is used on Windows). 08/19/2003: cheetah (William Fulton) [Java] Reworked std::string typemaps. Fixes a number of string in std namespace problems. For example %template vector. The templated class' get method wasn't returning a Java String, but a SWIGTYPE_p_string. Reported by Zach Baum. 08/15/2003: beazley Fixed [ 763522 ] 1.3.19 segfault in SwigType_add_pointer/DohInsertitem. Related to problem with unnamed class handling in Perl module. 08/15/2003: beazley Fixed [ 763563 ] Missing indication of optional arguments. Tcl module. Reported by Krzysztof Kozminski. 08/15/2003: beazley Fixed [ 787432 ] long param handled as int. Tcl module now uses Tcl_GetLongFromObj to convert integer values. 08/11/2003: beazley Fixed [ 775989 ] numeric template parameters. There were some errors in template expansion related to the use of arrays where the array dimension was a template parameter. It should work now. Reported by Bryan Green. 08/10/2003: mrose (Mark Rose) Added a director typemap (outv) for return by value and cleaned up up a few of the commented director typemaps. 08/10/2003: mrose (Mark Rose) Fixed constructor generation for director classes to ignore private constructors. Protected constructors are also ignored for now, pending a solution to the problem of wrapping classes that only define protected constructors. 08/07/2003: cheetah (William Fulton) New commandline option -outdir to specify where the language specific files are to be generated. This is useful for target languages like Python, Java etc which generate proxy files in the appropriate language. This option does not apply to the C/C++ wrapper file. 08/07/2003: cheetah (William Fulton) On Windows the generated files (other than the _wrap.c or _wrap.cxx files) were sometimes incorrectly being generated into the current directory unless the input file used the Unix path separator. The Windows path separator should now be used. Bug reported by Robert Davies. 08/07/2003: beazley Added array variable set typemap to Perl module. 08/07/2003: beazley Fixed [ 775677 ] Array init causes codegen bug.. 08/07/2003: beazley Fixed [ 779062 ] Class"\n"::foo not supported. SWIG should now correctly handle whitespace in between namespace qualifiers. For example "A :: Foo :: Bar". 07/31/2003: cheetah (William Fulton) Fixes for parameters which are classes that are passed by value and have a default value. A copy constructor for SwigValueWrapper is required (SF #780056). Also fixed memory leak in these circumstances. These mods also fix SF #780054. 07/28/2003: beazley Improved run-time error message for pointers in Python module. Contributed by Zooko. 07/10/2003: ballabio (Luigi Ballabio) [Almost all languages] Wrappers for std::pair added. Typemaps for Python, Ruby, Guile and MzScheme. 07/01/2003: mkoeppe (Matthias Koeppe) [Chicken] Handle the case of more than one argout typemap per function. 06/29/2003: cheetah (William Fulton) [Java, C#] SF #670949 request. The destructor wrapper function name is now configurable. A new attribute called methodname in the javadestruct/javadestruct_derived (Java) or csdestruct/csdestruct_derived (C#) typemaps specifies the method name. For example in Java the destructor is wrapped by default with the delete method: %typemap(javadestruct, methodname="delete") SWIGTYPE {...} 06/27/2003: cheetah (William Fulton) [Java, C#] The throws attribute for adding exception classes to the throws clause also now works with the following typemaps: newfree javain, javaout (Java) csin, csout (C#) For example, the 'AnException' will be added to the throws clause in the proxy function: %typemap(javaout, throws="AnException") int { int returnValue=$jnicall; if (returnValue==0) throw new AnException("Value must not be zero"); return returnValue; } 06/25/2003: mrose (Mark Rose) [Python] Director typemap marshalling checks for null pointers when walking the parameter list instead of relying soley on the parameter count. Cures a segfault that occured for multiple argument inv typemaps. Someone with more Swig experience should probably review this code. 06/24/2003: mkoeppe (Matthias Koeppe) [Chicken] Don't emit calls to "C_check_for_interrupt", which may result in an endless loop. Patch by felix@proxima-mt.de. 06/20/2003: cheetah (William Fulton) [C#] Finalizers now use destructor syntax as the override which was used in the Finalize method is not in the ECMA standards, spotted by the MS compiler. 06/10/2003: cheetah (William Fulton) [C#] A number of changes have been made to remove the Java naming that was used in the C# module. Typemap name changes: jni -> ctype jtype -> imtype jstype -> cstype javain -> csin javaout -> csout javainterfaces -> csinterfaces javabase -> csbase javaclassmodifiers -> csclassmodifiers javacode -> cscode javaimports -> csimports javaptrconstructormodifiers -> csptrconstructormodifiers javagetcptr -> csgetcptr javafinalize -> csfinalize Feature name changes: javaconst -> csconst javamethodmodifiers -> csmethodmodifiers Pragma changes: pragma(java) -> pragma(csharp) jniclassbase -> imclassbase jniclassclassmodifiers -> imclassclassmodifiers jniclasscode -> imclasscode jniclassimports -> imclassimports jniclassinterfaces -> imclassinterfaces Special variable name changes: $javaclassname -> $csclassname $javainput -> $csinput $jnicall -> $imcall This will break SWIG interface files that use these typemaps, features and pragmas. Please update your code or use macros for backwards compatibility. *** POTENTIAL INCOMPATIBILITY FOR C# MODULE *** 06/10/2003: mkoeppe (Matthias Koeppe) [MzScheme] Applied MzScheme module updates contributed by John Lenz . - Updated mzscheme to use SWIG's common runtime type system from common.swg. - The Lib/mzscheme directory has been reorganized to standardize names across the language modules: mzscheme.i was moved to mzscheme.swg, mzscheme.swg and mzschemedec.swg have been removed, mzrun.swg (which contains the runtime code) has been added. - The swig_proxy structure was renamed to swig_mz_proxy. swig_mz_proxy now contains a pointer to a swig_type_info structure. - Added varin and varout typemaps for SWIGTYPE [] and SWIGTYPE &. - Garbage collection by calling scheme_add_finalizer() has been added. *** NEW FEATURE [MzScheme] *** 06/10/2003: cheetah (William Fulton) [Java] New typemaps: javadestruct and javadestruct_derived for the C++ destructor wrapper. The javadestruct version gets used by classes at the top of an inheritance chain and the javadestruct_derived version gets used by other classes. [C#] cildispose and cildisposeoverride typemaps replaced by csdestruct and csdestruct_derived typemaps. The delete() method has been removed and its functionality put into these typemaps designed for the Dispose() method. - New typemaps csinterfaces and csinterfaces_derived replace the javainterfaces typemap. Also fixes the peculiarity of all classes in an inheritance chain individually deriving from the IDisposable interface. - New typemap csfinalize for finalizers. C++ destructors are now called by garbage collector during finalization. Problem reported by Andreas Schörk. 06/10/2003: Tiger Modified contract code for error message output. Contract code can now print out simple error message. Modified contract code to prepare for inheritance 06/03/2003: mkoeppe [Guile] Applied Guile module updates contributed by John Lenz . - SWIG currently uses Guile's gh_ API, which is marked as deprecated in Guile 1.6 and will be removed in Guile 1.9. This change introduces a command-line flag "-scm" which causes SWIG to generate wrappers that use Guile's SCM API instead; this requires Guile >= 1.6. - The Lib/guile directory has been reorganized to standardize names across language modules: guiledec.swg and guile.swg have been moved into guile_gh_run.swg, guile.i has been moved to guile_gh.swg, guile_scm.swg and guile_scm_run.swg which contain the SCM API stuff have been added - ghinterface.i, which contains the defines from the gh_ functions to the scm_functions has been added - The API for dealing with pointer objects is now SWIG_ConvertPtr, SWIG_MustGetPtr, SWIG_NewPointerObj. - Added varin and varout typemaps for SWIGTYPE [] and SWIGTYPE & - Garbage collection has been added. *** NEW FEATURE [Guile] *** 06/01/2003: cheetah (William Fulton) Dimensionless arrays such as int foo[] = {1, 2}; extern int bar[]; produce a warning that the variable is read-only. Depending on the target language, this used to cause compile errors or generate a setter that generated a runtime error. A setter cannot be automatically generated because the array size cannot be determined by SWIG. A varin, globalin or memberin typemap (depending on the target language) must be written by the user. 05/29/2003: beazley Refinement to default typemap matching and arrays. When an array is declared like this: int foo[4]; The default typemap now resolves to SWIGTYPE [ANY] If no match is found for that, it then resolves to SWIGTYPE [] If no array dimension is specified in the original declaration, the SWIGTYPE [] is used right away. Note: This change has been made to resolve problems related to arrays with and without dimensions. For example, sometimes SWIG was generating setter functions for array variables with no dimensions (an error). Likewise, SWIG sometimes made arrays with dimensions read-only (also an error). This fixes the arrays_global test problem. 05/28/2003: beazley Fixed subtle type handling bug with references and pointers. If you had functions like this: typedef Foo Bar; Foo *func1(); void func2(Bar &x); Then func2() wouldn't accept objects returned by func1() because of a type error. It should work now. Reported by Brian Yang. 05/21/2003: cheetah (William Fulton) Fixes to some of the Visual C++ example project files which would not work with spaces in the paths held in the environment variables used to point to the target language's library / include directory. SF bug #740769 05/21/2003: songyanf (Tiger) Added -contracts option. First try of the idea of "Wrap by Contract": build up realiable cross-language module by wrapping with SWIG. Implemented basic assertion (preassertion & postassertion & invariant) for simple C/C++ functions. Current format of contracts are: %contract class_name :: func_name (paras...) { require: boolean exprs; exprs; ensure: boolean expr; exprs; invariant: boolean expr; exprs; } *** NEW FEATURE *** 05/19/2003: cheetah (William Fulton) Build tweaks. There were a few preprocessor definitions which were specified in the Makefile for passing on the commandline when compiling. These are now all defined in swigconfig.h. Autoconf doesn't normally allow installation directories to be defined in this config header file, but an autoconf archive macro enables this. This macro along with future autoconf macros are going to be put in the Tools/config directory. 'swig -version' now reports the target build platform. 05/11/2003: cheetah (William Fulton) [C# and Java] Fix to the following typemaps: javabase, javainterfaces, javaimports, javaclassmodifiers, javaptrconstructormodifiers, javafinalize, javagetcptr & javacode. These are the typemaps for modifying/generating proxy classes. Previously the typemaps would use the proxy class name and not the C++ type, which was inconsistent with all other typemaps. In most circumstances the proxy class name and the C++ class name/type is the same except for classes in namespace, templated classes etc. so this shouldn't affect most cases. *** POTENTIAL INCOMPATIBILITY FOR JAVA and C# MODULES *** 05/09/2003: cheetah (William Fulton) Visual C++ Project files have been added so that the runtime libraries can be built on Windows (for Tcl, Perl, Python and Ruby). 05/01/2003: beazley Fixed problem with return by value, const, and private constructors. For example: class B { private: B(); public: B(const B&); }; class A { ... const B returnB() const; ... }; Problem and patch suggestion reported by Bill Hoffman. 04/29/2003: cheetah (William Fulton) Build changes: - Single autoconf invocation - autoconf in the Tools directory has gone. - Libtool bootstrapped when running autogen.sh. This requires anyone using the cvs version of SWIG to have libtool installed on their machine. Suggest version 1.4.2 or higher, preferably the latest - 1.5. - Automake is now used to build the runtime libraries in conjunction with libtool. - Runtime libraries are now successfully built as DLLs on Cygwin. - Skipping languages is no longer just determined in the top level makefile but in configure.in. This info is used for building the runtime libraries and for running the examples and test-suite. - These changes have fixed multiple build directory builds, that is building from directories other than the top level directory. Installation from multiple build directories also working. An initial configure in the top level directory is no longer needed as described in 04/02/2003 entry. A 'make distclean' will be needed before building in a directory other than the top level directory if the autotools have been run from this top level directory at some point, but autoconf will tell you this. Note that 'make check' only works from the top level directory at the moment. 04/28/2003: beazley Fixed [ 723471 ] Wrapper_print() fails with preprocessor directives. 04/28/2003: beazley Minor refinement of const static member variable handling described in CHANGES 08/11/2002. Previously, SWIG merely checked to see if there was an initializer in the declaration. Now, SWIG additionally checks to make sure the static member is const. 04/25/2003: ljohnson (Lyle Johnson) [Ruby] Added a kind of limited support for multiple inheritance, activated using the -minherit command-line option. I've also updated the "C++ Inheritance" section of the Ruby documentation to discuss how this works, and its limitations. Also also modified the minherit.i test case to run against this. 04/25/2003: ljohnson (Lyle Johnson) [Ruby] Added the -globalmodule command-line option for the Ruby module, for wrapping stuff into the global module (Kernel) instead of a nested module. Updated documentation accordingly. 04/23/2003: mrose (Mark Rose) Fixed symname error in director calls to Python methods that extend C++ operators. Stopped director destructor wrappers from calling __set_up, which was leaving the director flag in an inconsistent state. 04/23/2003: beazley Fixed problem with namespace resolution and nested namespaces. Reported by Alfred Lorber (and Marcelo Matus). 04/16/2003: cheetah (William Fulton) Patch for Java examples and test-suite to run on Mac OS X. 04/15/2003: ljohnson (Lyle Johnson) [Ruby] Incorporated Nobu Nakada's patches for supporting the Ruby 1.8 allocation framework. 04/15/2003: ljohnson (Lyle Johnson) [Ruby] Replaced all uses of the deprecated STR2CSTR() macro with the safer StringValuePtr() macro. For more information, see ruby-talk:67059 and follow-ups to that post. 04/11/2003: beazley Fixed problem with preprocessor macro expansion. For example: #define min(x,y) ((x) < (y)) ? (x) : (y) int f(int min); Reported by Sebastien Recio. 04/10/2003: cheetah (William Fulton) [Java] Added a runtime check to typemaps in arrays_java.i library to check that the Java array passed in is the same size as the C array and throw an exception if not. Also fix to use delete instead of free for arrays created using new. 04/07/2003: cheetah (William Fulton) Remove GCC3 warning when compiling the examples and test-suite: cc1plus: warning: changing search order for system directory "/usr/include" cc1plus: warning: as it has already been specified as a non-system directory See SF patch #715531 submitted by Gerald Williams 04/03/2003: cheetah (William Fulton) [C#] Improved wrapping of enums and constants. These were previously wrapped as C# variables rather than constants. Either these are wrapped as readonly (runtime) constants or compile time constants, depending on the %javaconst directive (The directive is likely to change name soon). For example wrapping: %javaconst(0); #define ABC 22 %javaconst(1) XYZ; #define XYZ 33 is now: public static readonly int ABC = examplePINVOKE.get_ABC(); public const int XYZ = 33; 04/03/2003: cheetah (William Fulton) [Java] Global constants and enums are put in their own interface called xxxConstants, where xxx is the module name. This is an improvement as it is possible to derive (implement) a Java class from the xxxConstants interface to improve the syntax; namely when wrapping: enum {ONE=1, TWO, THREE}; accessing these from a Java class implementing xxxConstants is neater: int number = ONE; than the previous: int number = xxx.ONE; Patch submitted by Dave Dribin. 04/02/2003: cheetah (William Fulton) Build improvements for multiple builds. This allows one to build the SWIG executable and runtime libraries for different platforms/compilers etc by running configure in different directories. This isn't 100% just yet and won't be until libtool is better configured... a 'configure' and 'make distclean' needs to be run in the root directory before it all works. For example: $ ./configure $ make distclean $ mkdir config1; cd config1; ../configure CC=gcc CXX=g++; make; cd .. $ mkdir config2; cd config2; ../configure CC=cc CXX=c++; make; cd .. To be improved. A 'make check' does not work yet either. 04/01/2003: beazley Fixed template partial specialization argument expansion bug. This showed up when trying to use std_vector.i with vectors of pointers. 03/31/2003: cheetah (William Fulton) Fix for parallel make builds of SWIG, for example make -j 4 Build failure reported by Bill Clarke. 03/28/2003: beazley Released 1.3.19.
