boost::python: marshalling buffers
by Christoph Rupp April 23, 2012

April 23, 2012

Hi, i have a C++ class that i'm wrapping with boost::python: class Foo { // ... const char *get_buffer(); size_t get_size() const; // ... }; I want to send this class through a thrift interface (which uses the write() method to send the data to a file or a socket). For a few days now i'm trying to implement this. By now i understand that i have to implement the buffer protocol, and i know that i can create a buffer with boost::python (read-only access is sufficient): inline object as_buffer(const Foo &f) { return object (handle<> (PyBuffer_FromMemory ((void*)f.get_buffer(), f.get_size()))); } (This is based on an email from 2009 that i found in this mailing list's archive.) But i do not know how to glue it together to form a full module. This is how the module looks right now: BOOST_PYTHON_MODULE(Foo) { class_<Foo, boost::noncopyable>("Foo", init<int32_t, bool>()) .def("add", afn) .def("finalize", &Foo::finalize) .def("empty", &Foo::empty) .def("clear", &Foo::clear) ; } How can i include that buffer conversion? Thanks a lot, Christoph

Python.Boost + Python2.7 + VS2008 issues
by JS Unkn0wn April 19, 2012

April 19, 2012

-:Background:- I am working on a cross platform project (Win32 with proprietary graphics lib, and a proprietary embedded device running a custom OS with custom compilers) -:Goals:- Using Boost.Python on both platforms (without dlls, as we will have to embed Python anyway). -:Problems:- Receiving <<fatal error C1189: #error : "Mixing a dll boost library with a static runtime is a really bad idea...">> in /MT, which is concerning to me since compiling as a DLL works but I must be able to deploy this on a system that has no DLL system. -:Setup steps taken so far (in order), and system config:- 1 - Windows XP Pro + SP3 2 - Visual Studio 2008 Standard + Service Pack (C++ and C# installed) 3 - Python 2.7 installed 4 - Boost Pro 1.47 installer for Windows installed (c:\boost_1_47) 5 - Boost 1.47 copied to (c:\boost_1_47_0) 6 - Boost Build 1.47 downloaded ... I've written a much more detailed log here ( http://jsperfunkn0wn.blogspot.co.uk/2012/04/installing-boostpython-python-2… ). Here is the code I am trying to compile: http://pastebin.com/Rg2AeTms Regards, JSPerf Unkn0wn

Assign ownership of Python-constructed object to C++ runtime
by Adam Preble April 17, 2012

April 17, 2012

I am pondering trying to eliminate some usages of shared pointers in my code since I have finally completed enough of it that I have good ownership rules for things in place. I still have one spot, which is basically the main door to the C++ runtime, where I have a problem. I've been creating instances of some objects in Python, with the purpose of assigning to another object for safekeeping. Really that other object is what I have in mind for managing everything about these objects--including their runtimes. But I see the objects get destroyed when the Python declaration for them go out of scope. That would normally be the right thing. I'm trying to think of alternatives. The best I can think of is to use a static factory method instead that returns an internal reference. I'm intend to experiment with that now but I am wondering if there are some other things to consider instead. Inevitably somebody will ask why I'm doing away with the shared pointers. I have some cycles due to communication that means a lot of stuff never actually gets deleted due to the reference-counting methodology in them. When I used weak references, I found they were getting deleted too eagerly. And by this point, I otherwise have gotten an ownership hierarchy down.

Define class in 2 scopes without re-exposing
by John Reid April 16, 2012

April 16, 2012

Hi, If I want to define the same class (Inner) in 2 different scopes (Outer1 and Outer 2), I can do it like this: #include <boost/python.hpp> struct Outer1 {}; struct Outer2 {}; struct Inner {}; BOOST_PYTHON_MODULE( _sandbox ) { namespace bp = ::boost::python; { bp::scope scope = bp::class_< Outer1 >( "Outer1" ); bp::class_< Inner >( "Inner" ); } { bp::scope scope = bp::class_< Outer2 >( "Outer2" ); bp::class_< Inner >( "Inner" ); } } Unfortunately when I import the _sandbox module I get the standard error: RuntimeWarning: to-Python converter for Inner already registered; second conversion method ignored. and in debug build the second Inner registration asserts. Is there any way to test if Inner is already registered and if so just place it in the correct scope? Perhaps replacing the second scoped block with something like this: { bp::object class_Outer2 = bp::class_< Outer2 >( "Outer2" ); bp::type_info info = boost::python::type_id< Inner >(); const bp::converter::registration * reg = bp::converter::registry::query( info ); if( NULL == reg ) { bp::class_< Inner >( "Inner" ); } else { // Some magic here! } } Also I should say that the 2 scoped blocks of code aren't adjacent in my library so I don't really want to pass objects between them. I'm hoping for a solution that just extracts info from the boost.python registry. Thanks for any help, John.

overloaded functions and order of arguments
by Holger Brandsmeier April 12, 2012

April 12, 2012

Dear list, I exported the C++ function `sin` both for real and complex numbers (`float` and `complex` in python / `double` and `std::complex` in C++) and I noticed that calling `sin(2.3)` gives `(0.7457052121767203-0j)` so a complex number. Why is that? In which order does boost python handle overloading of functions anyways? More precisely I exported this function to python >>> sin? Type: function Base Class: <type 'builtin_function_or_method'> String Form: <Boost.Python.function object at 0x26358e0> Namespace: Interactive Docstring: sin( (float)arg1) -> float : C++ signature : double sin(double) sin( (complex)arg1) -> complex : C++ signature : std::complex<double> sin(std::complex<double>) Notice in particular that the `float` version is above the `complex` version, so if boost::python things this is ambiguous (I don't condider this abiguous), but even if so I was kind of expecting him to use the first exported function, not the second. Any ideas? -Holger

std::complex vs python complex
by Holger Brandsmeier April 12, 2012

April 12, 2012

Dear list, I exported a wrapper for std::complex<double> to python and I am willing to always use this class in python and I never want to use pythons own `complex` data type. However, a funny thing happens when I export the addition operator (the implemenation is given in the STL ...) .def(self + self) Now I get that: type(scalar_cd(1,2) + scalar_cd(1,2)) <type 'complex'> But my own type is of the form: type(scalar_cd(1,2)) <class 'parfem.scalarPy.scalar_cd'> Why did this happen and how can I avoid this? Later own I get problems when I want to pass this back to C++. I remember that pythons own complex type is a bit special and does not cooperate nicely with boost::python and std::complex<> but how did python/boost::python end up converting the result of the addition to `complex`? I am using: Python 2.7.2 boost-1.46.1 Best regards, Holger Brandsmeier

Problem Compiling Boost.Python Example
by Payam Shiva April 7, 2012

April 7, 2012

Hi, I have trouble compiling the simplest examples with Boost.Python. I hope you could help me find out what I'm doing wrong. I am using Microsoft Visual C++ 2010 on 64-bit Windows 7. I use 64-bit version of Python 2.7.2 from Enthought Python Distribution 7.2-2. I installed Boost as described in "Simplified Build From Source" section of Boost getting started guide, i.e. going to Boost.Build directory and typing: bootstarp .\b2 Boost compiled without errors (except for a warning about MPI). Then I created user-config.jam in my home directory containing the following lines: using msvc : 10.0 ; using python : 2.7 : C:\\Python 27 ; Then I tried compiling the tutorial example, but I got the following messages (and no DLL): C:\Boost\boost_1_49_0\libs\python\example\tutorial> bjam ...patience... ...patience... ...found 1592 targets... ...updating 10 targets... msvc.link.dll

Downloading Boost sources from school and building them at home is the only way for me to install Boost, because BoostPro doesn't offer an offline installer. (Well, it does. But only for enterprise customers. That's not an option for me either)

Boost::Python to_python converter
by DarkAnt April 3, 2012

April 3, 2012

I'm having a conceptual issue with the way C++ interfaces with Python. I'm trying to convert a C++ object to a Python object, but my attempt causes the program to crash. I suspect I'm doing a lot of things wrong. Ultimately I'd like to be able to pass C++ objects to a python function that modifies their values. #include <boost/python.hpp> #include <string> struct Unit { int health; std::string name; std::string type; std::pair<int,int> coord; }; struct Unit_to_python { static PyObject* convert(Unit const& unit) { return boost::python::incref(boost::python::object(unit).ptr()); } }; BOOST_PYTHON_MODULE(game) { boost::python::class_<Unit>("Unit") .def_readwrite("health", &Unit::health) .def_readwrite("name", &Unit::name) .def_readwrite("type", &Unit::type) .def_readwrite("coord", &Unit::coord) ; } int main(int argc, char** argv) { Py_Initialize(); boost::python::to_python_converter<Unit, Unit_to_python>(); Unit unit1; unit1.health = 100; unit1.name = "Tank"; unit1.type = "Armor"; boost::python::object foo(unit1); // crash: stack overflow return 0; }

wrapped std::vector slice affecting items in a python list
by babak April 2, 2012

April 2, 2012

Hi, I've come across some unusual behaviour that I was hoping some one might be able to explain to me. In python I have a list and a wrapped std::vector<MyCustomType> (using the vector_indexing_suite) where the list contains the items in the vector. If I slice insert items into the vector then the items in the python list change. The attached example illustrates this. Is this behaviour expected ? I'm quite confused as to what's going on so any help clarifying this would be greatly appreciated. thanks, Babak http://boost.2283326.n4.nabble.com/file/n3738972/test.py test.py http://boost.2283326.n4.nabble.com/file/n3738972/source.cpp source.cpp -- View this message in context: http://boost.2283326.n4.nabble.com/wrapped-std-vector-slice-affecting-items… Sent from the Python - c++-sig mailing list archive at Nabble.com.
