Boost.Python. The major change is that, instead of being
boost::function2<PyObject*,PyObject*,PyObject*>, py_function is now a
runtime-polymorphic wrapper for compile-time polymorphic
behavior (just like function) of our own which carries more
information/behaviors. In particular, you can retrieve an array of
c-strings describing the types in the function signature.
Additionally, the minimum and maximum arity are stored in the
py_function object instead of in the 'function' object which wraps it.
* data_members.hpp -
Adjustments for the new py_function. Workarounds for CodeWarrior
Pro 8.3 bugs in function template argument deduction with
pointers-to-members.
* has_back_reference.hpp, test/back_reference.cpp,
test/select_holder.cpp -
Updated to follow the metafunction protocol
* init.hpp, detail/defaults_gen.hpp -
Make Keywords a more-specific type in function signatures to
prevent string literals that show up as char[N] from binding to
the wrong argument (at least Intel 7.1 for Windows does this).
* make_function.hpp -
Adjustments for the new py_function. Arities are now computed
by caller<>.
* opaque_pointer_converter.hpp, type_id.hpp -
Use BOOST_NO_EXPLICIT_FUNCTION_TEMPLATE_ARGUMENTS facilities;
generate specializations that all compilers can handle.
* raw_function.hpp -
Adjustments for the new py_function.
* caller.hpp -
Added arity and signature type name reporting.
* detail/config.hpp
Enable __declspec(dllexport) for Cygwin, thereby fixing the
recent horrible Cygwin linking problems.
* detail/msvc_typeinfo.hpp -
Always pass boost::type<T>* explicitly, thereby working around
incompatible notions of how to specialize function templates with
default arguments on various compilers.
* object/function.hpp
, object/function_handle.hpp
, object/function_object.hpp
, object/function_object.cpp
Adjustments for the new py_function. Arities are carried by
py_function.
* object/iterator.hpp, object/iterator.cpp
Adjustments for the new py_function; we have to compute a
signature of types to construct it with.
* object/py_function.hpp
Removed dependency on boost::function; see the comment at the
top of this entry for more details.
* object/select_holder.hpp
Clean up to more closely follow MPL idioms.
* test/Jamfile -
Adjust the embedding test for the new Cygwin use of declspec.
Update bases and pointee tests with missing properties.
* test/input_iterator.cpp -
Updates for the new iterator adaptors.
* test/opaque.py -
Add Python encoding comment to suppress PendinDeprecationWarning
with recent Python builds.
* test/str.cpp
Pass a Python long instead of a float to string.expandtabs,
suppressing a PendinDeprecationWarning with recent Python builds.
* libs/utility/counting_iterator_example.cpp
Borland workaround
* libs/utility/indirect_iterator_example.cpp
const-correctness fix.
