- This fixes the problem of no reaching parent class variables.
Note: Any extra variables set by __set function are stored in the parent class's extras
hastable under swig_object_wrapper.
- This fixes director_basic test case. Uses the new flow in director class methods.
- It also correctly fixes the double free problem in director_detect.
- Rename class entry variables to SWIGTYPE_class_ce
- Refactor factory code to use SWIGTYPE_class_ce to create objects
- Refactor ConvertPtr to work of wrapped class objects.
- Change the need of runtime check on old or new flow at wrapper generation time.
- Change the check on add ZEND_ACC_ABSTRACT to GetFlag(n, "abstract") && Swig_directorclass(Swig_methodclass(n))
- workaround to solve abstract testcases at the moment.
- Remove redundant code in class handler for getting namespaces (Not the correct approact) and use of zend_register_class_alias_ex.
- Refactor choosing of class name to use sym:name by default.
- Change enum_scope_template test to use class enums.
- Move the conversion of void* of ptr in swig wrapper to class pointer to Lib files.
- Synchronize between old and new flow. Old flow to accept newly created objects,
with the use of a new property SWIG_classWrapper to newly created objects.
- ZEND_BEGIN_ARG_INFO_EX to hold exact number of arguments required.
- Fix the constructor overloading bug in the in-house Swig_class_overload_dispatch function
- Add helper function to check if the class is wrapped.
- Add ZEND_ACC_ABSTRACT to virtual functions to make the class abstract.
- Change how wname is selected for staticmemberfn.
- Helper function to get names without namespace getNameWithoutNamespace.
- Fix bugs on class entry level at class handler.
- Move all entry level code to class handler from class decleration.
- Checking if base.item is null before using it.
- Check if the parent class is wrapped before using its class entry.

Typemap change for templates
Fixes#1051. Using declarations to templates were missing in SWIG's internal typedef tables.
This led to a few problems, such as, templates that did not instantiate and generated
C++ code that did not compile as SWIG did not know what scope the template was
in. This happened mostly when a using declaration was used on a template type in a
completely unrelated namespace.
Fix some cases of type lookup failure via a combination of both using directives and
using declarations resulting in C++ code that did not compile as the generated type was
not fully qualified for use in the global namespace. Example below:
namespace Space5 {
namespace SubSpace5 {
namespace SubSubSpace5 {
struct F {};
}
}
using namespace SubSpace5;
using SubSubSpace5::F;
void func(SubSubSpace5::F f);
}
The scoping rules around %template have been specified and enforced.
The %template directive for a class template is the equivalent to an
explicit instantiation of a C++ class template. The scope for a valid
%template instantiation is now the same as the scope required for a
valid explicit instantiation of a C++ template. A definition of the
template for the explicit instantiation must be in scope where the
instantiation is declared and must not be enclosed within a different
namespace.
For example, a few %template and explicit instantiations of std::vector
are shown below:
// valid
namespace std {
%template(vin) vector<int>;
template class vector<int>;
}
// valid
using namespace std;
%template(vin) vector<int>;
template class vector<int>;
// valid
using std::vector;
%template(vin) vector<int>;
template class vector<int>;
// ill-formed
namespace unrelated {
using std::vector;
%template(vin) vector<int>;
template class vector<int>;
}
// ill-formed
namespace unrelated {
using namespace std;
%template(vin) vector<int>;
template class vector<int>;
}
// ill-formed
namespace unrelated {
namespace std {
%template(vin) vector<int>;
template class vector<int>;
}
}
// ill-formed
namespace unrelated {
%template(vin) std::vector<int>;
template class std::vector<int>;
}
When the scope is incorrect, an error now occurs such as:
cpp_template_scope.i:34: Error: 'vector' resolves to 'std::vector' and
was incorrectly instantiated in scope 'unrelated' instead of within scope 'std'.
Previously SWIG accepted the ill-formed examples above but this led to
numerous subtle template scope problems especially in the presence of
using declarations and using directives as well as with %feature and %typemap.
Actually, a valid instantiation is one which conforms to the C++03
standard as C++11 made a change to disallow using declarations and
using directives to find a template.
// valid C++03, ill-formed C++11
using std::vector;
template class vector<int>;
Similar fixes for defining classes using forward class references have
also been put in place. For example:
namespace Space1 {
struct A;
}
namespace Space2 {
struct Space1::A {
void x();
}
}
will now error out with:
cpp_class_definition.i:5: Error: 'Space1::A' resolves to 'Space1::A' and
was incorrectly instantiated in scope 'Space2' instead of within scope 'Space1'.
For templates only, the template parameters are fully resolved when
handling typemaps. Without this, it is too hard to have decent rules
to apply typemaps when parameter types are typedef'd and template
parameters have default values.
Fixes %clear for typedefs in templates, eg:
%typemap("in") XXX<int>::Long "..."
template typename<T> struct XXX {
typedef long Long;
};
%clear XXX<int>::Long;
as the typemap was previously incorrectly stored as a typemap for long
instead of XXX<int>::Long.
Code Refactor
- Refactor code for return type of SWIGTYPE
- Workaround for Namespaced classes.
- Refactor code of SWIG_SetZval to take care of objects in class constructor.
- Introduce SWIG_generalize_object to generalize each object to swig object wrapper.
- Catch feature:immutable instead of feature:warnfilter - 462 for missing setter.
- Refactor code to create PHP objects for all instances of value, reference and pointer return types of C++ objects.
This applies for conversion operators too.
- Introduce getAccessMode to get the Access Mode of a method for generating Wrapper.
- Refactor free_object creation to include need_free condition. This is to check if there is a need to free.
Example where it isn't required to free - (Virtual Protected Destructors).
- Support for feature:exceptionclass. Extends class Exception.
- Improve condition check in Director class constructor to distinguish between, extended class creation or not.
Swig::Director::swig_is_overridden_method is used.
