The SWIG_PyInstanceMethod_New method is no longer added to wrapped
classes except when it's actually needed, which is when
(!builtin && fastproxy) is true (which it isn't by default).
The SWIG_PyStaticMethod_New method is no longer is now similarly
gated - previously only (fastproxy) was checked.
Finally the C/C++ functions that implement these were always compiled
into the module, but now they're only included if
(!builtin && fastproxy) is true.
Issue noted by vadz in #2190.
When not using -builtin, the self parameter is now still made
available so that user typemaps can use it. Fixes#967.
When using -builtin, fix -Wunused-parameter warnings in the generated
wrapper code. See #801.
Based on a commit peeled out of #801 by teythoon.
Use SWIG_<module>_Init() function to init the module rather than
<module>_Init() as the latter can collide with a function being wrapped.

Remove redundant NULL checks before free()/delete
The ISO C and C++ standards guarantee that it's safe to call these
on a NULL pointer, so it's not necessary for the calling code to
also check.

Since the switch to wrapping classes using PHP's C API, we now
internally need to be able to tell if a PHP object is of or derived
from a class that is wrapped by SWIG so we know if we can offset the
zend_object pointer to get to the swig_object_wrapper. If we try to
do this to an object which isn't wrapped by SWIG then we invoke C/C++
undefined behaviour (and typically get a segmentation fault).
This check is implemented by having a SWIG\wrapped empty interface which
we make all SWIG-wrapped classes implement simply so we can test for it
to detect such classes.
Fixes#2125
As discussed and agreed in #1629, it's become hard to test with Perl
5.6 or earlier, such old versions are no longer in active use, and
4.1.0 is an appropriate time to make such a change.
I've dropped the compatibility code that was obvious to me, but there's
probably more that can be cleaned up now.
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.
Previously the zend_class_entry for Foo was named SWIGTYPE_Foo_ce, but
this can collide in some cases - e.g. if there's a class named p_Foo
then its zend_class entry will be SWIGTYPE_p_Foo_ce, but that's the same
as the swig_type_info for a class named p_Foo_ce.
Do more initialisation at module load time.
Use a shared set of handlers for cases when the C/C++ object is
destroyed with free().
Most of the code in the free_obj and create_object handlers is the
same for every wrapped class so factor that out into common functions.
Move this function definition to cexcept.swg from the code and only
define it if SWIG_swig_check_DEFINED is not defined yet, which both
simplifies the code in C.cxx and makes exception handling code more
flexible, as it's now possible to predefine SWIG_swig_check_DEFINED
in the code injected into the "cxxheader" section to replace the default
implementation. Show an example of doing this in the documentation and
document handling exceptions with C API too.
The changes above required adding a new "cxxcode" section, corresponding
to the "implementation" part of C++ wrappers and defining a new
SWIG_CXX_WRAPPERS preprocessor symbol to allow only adding C++-specific
code when C++ wrappers are actually generated. Also improve the
documentation of the C-specific sections in the manual.
This ensures that global functions can also use C++ classes, enums etc
for their parameters and return types.
C++ wrappers for a couple of tests had to be disabled, but this is not
really a regression as wrapping global functions just made apparent
problems that were not visible before because the corresponding wrappers
were not created at all.
The type of the member may be incomplete, so generate the definitions of
these functions in a separate section, after declaring all the wrapper
classes, just as it was already done for the other functions.
This fixes compiling some of the previously failing tests in C++ mode.
Use the base type, not the full type, to deal with the special case of
references to pointers which are blacklisted by classLookup(), for some
reason, but can be represented at C wrappers level.
No real changes, just factor out the code for (non-special) functions
generation from emit_member_function() into a separate
cxx_function_wrapper class, so that it could be reused for the global
functions generation too.
We must use the string for the resolved type, i.e. after replacing
typedefs with their expansions, as otherwise typedefs could leak into
the generated header.
In principle it might be possible to actually use the original typedefs
in the C++ part of the wrappers, but then we'd need to propagate the
typedef definitions there too and we don't do it currently.
