Boost timer initialization hangs in win_therad.ipp
by chaitanya sonavale 12 Mar '12

12 Mar '12

Hi, I have a C++ DLL which has exported functions which is used in a C# application via DllImport. The C++ DLL is linked to various .lib files which use boost functionality (thread, asio etc) internally and are compiled with BOOST_ALL_DYN_LINK option. When I run the application it just hangs with following stack trace. I get the same results if I convert this to a C++\CLI DLL and use it directly from the C# application. Stack Trace: ------------------------------------------------ OneComShim.dll!boost::asio::detail::win_thread::start_thread(boost::asio::detail ::win_thread::func_base * arg=0x035574f0, unsigned int stack_size=0x00010000) Line 98 + 0xe bytes C++ OneComShim.dll!boost::asio::detail::win_thread::win_thread<boost::asio::detail:: win_iocp_io_service::timer_thread_function> (boost::asio::detail::win_iocp_io_service::timer_thread_function f={...}, unsigned int stack_size=0x00010000) Line 72 C++ OneComShim.dll!boost::asio::detail::win_iocp_io_service::do_add_timer_queue(boos t::asio::detail::timer_queue_base & queue={...}) Line 471 + 0x31 bytes C++ OneComShim.dll!boost::asio::detail::win_iocp_io_service::add_timer_queue<boost:: asio::time_traits<boost::posix_time::ptime> > (boost::asio::detail::timer_queue<boost::asio::time_traits<boost::posix_time::pt ime> > & queue={...}) Line 78 C++ OneComShim.dll!boost::asio::detail::deadline_timer_service<boost::asio::time_tra its<boost::posix_time::ptime> >::deadline_timer_service<boost::asio::time_traits<boost::posix_time::ptime> > (boost::asio::io_service & io_service={...}) Line 68 C++ OneComShim.dll!boost::asio::deadline_timer_service<boost::posix_time::ptime,boos t::asio::time_traits<boost::posix_time::ptime> >::deadline_timer_service<boost::posix_time::ptime,boost::asio::time_traits<boos t::posix_time::ptime> >(boost::asio::io_service & io_service={...}) Line 73 C++ OneComShim.dll!boost::asio::detail::service_registry::create<boost::asio::deadli ne_timer_service<boost::posix_time::ptime,boost::asio::time_traits<boost::posix_ time::ptime> > >(boost::asio::io_service & owner={...}) Line 81 + 0x2f bytes C++ OneComShim.dll!boost::asio::detail::service_registry::do_use_service(const boost::asio::io_service::service::key & key={...}, boost::asio::io_service::service * (boost::asio::io_service &)* factory=0x100c770d) Line 123 + 0xc bytes C++ OneComShim.dll!boost::asio::detail::service_registry::use_service<boost::asio::d eadline_timer_service<boost::posix_time::ptime,boost::asio::time_traits<boost::p osix_time::ptime> > >() Line 49 C++ OneComShim.dll!boost::asio::use_service<boost::asio::deadline_timer_service<boos t::posix_time::ptime,boost::asio::time_traits<boost::posix_time::ptime> > > (boost::asio::io_service & ios={...}) Line 34 C++ OneComShim.dll!boost::asio::basic_io_object<boost::asio::deadline_timer_service< boost::posix_time::ptime,boost::asio::time_traits<boost::posix_time::ptime> > >::basic_io_object<boost::asio::deadline_timer_service<boost::posix_time::ptime, boost::asio::time_traits<boost::posix_time::ptime> > >(boost::asio::io_service & io_service={...}) Line 91 + 0x4b bytes C++ OneComShim.dll!boost::asio::basic_deadline_timer<boost::posix_time::ptime,boost: :asio::time_traits<boost::posix_time::ptime>,boost::asio::deadline_timer_service <boost::posix_time::ptime,boost::asio::time_traits<boost::posix_time::ptime> > >::basic_deadline_timer<boost::posix_time::ptime,boost::asio::time_traits<boost: :posix_time::ptime>,boost::asio::deadline_timer_service<boost::posix_time::ptime ,boost::asio::time_traits<boost::posix_time::ptime> > >(boost::asio::io_service & io_service={...}) Line 147 C++ OneComShim.dll!CORE::SERVER_COMMUNICATOR::CurlHandler::CurlHandler(CORE::SERVER_ COMMUNICATOR::ServerAgent * serverAgent=0x1029c950) Line 37 + 0x118 bytes C++ OneComShim.dll!CORE::SERVER_COMMUNICATOR::ServerAgent::ServerAgent() Line 22 C++ OneComShim.dll!`dynamic initializer for 'CORE::SERVER_COMMUNICATOR::ServerAgent::agent''() Line 17 + 0x28 bytes C++ TestWin.exe!TestWin.Program.Main(string[] args = {string[0x00000000]}) Line 16 + ------------------------------------------------ As it can be seen, it stops in start_thread inside win_thread.ipp at following lines on WaitForSingleObject if (entry_event) { ::WaitForSingleObject(entry_event, INFINITE); ::CloseHandle(entry_event); } I am just creating a timer object in the code and do not understand why it leads to this situation.

Keynotes for C++ Now!
by Jon Kalb 11 Mar '12

11 Mar '12

C++ Now! (formerly BoostCon) is pleased to announce its lineup of keynote speakers for the 2012 conference: Howard Hinnant, Sean Parent, and Daveed Vandevoorde. Howard Hinnant is the principal author of libc++, the standard C++ library implementation used by the Clang compiler. During the development of C++11, Howard served as chairman of the C++ Standards Committee¹s Library Working Group, and is largely responsible for the design of what Scott Meyers has called the language¹s ³flagship new feature:² rvalue references. His keynote will demonstrate how rvalue references are used in move semantics and perfect forwarding. Sean Parent is a principal scientist and software architect for Adobe¹s mobile digital imaging group and formerly managed Adobe¹s Software Technology Lab. He was also the keynote speaker for the very first BoostCon, where he gave one of the most inspiring and memorable talks we¹ve ever had. We¹re very pleased to welcome him back for an encore. He will be speaking on what¹s next for C++ programmers: how do we write beautiful code that truly exploits today¹s hardware and infrastructure? Daveed Vandevoorde is a compiler developer with Edison Design Group, the author (with Nicolai Josuttis) of ³C++ Templates: The Complete Guide,² a co-founder of comp.lang.c++.moderated, and one of the few C++ Committee Members who is equally comfortable working on library design, language evolution, or the arcana of core language issues. Daveed is currently a leader in the effort to add true modules to the C++ language. He¹ll be talking about the design of the C++ modules feature and what it would mean for the future of the language. ³We are thrilled to have such a powerhouse lineup in the first year of the new language standard,² said Dave Abrahams the conference founder and co-chair. ³C++Now! 2012 is truly shaping up to be a feast for the C++ enthusiast.² C++ Now! 2012 will be held May 13-18 in Aspen Colorado. Registration is now open at http://cppnow.org/registration/. Keynote details at http://cppnow.org/overview/. Jon Co-Chair C++ Now!

Strange error while using BOOST_FOREACH
by John M. Dlugosz 11 Mar '12

11 Mar '12

I used BOOST_FOREACH with a collection whose iterator is derived from boost::iterator_adaptor. I got this: 7>E:\boost_1_47\boost/range/iterator.hpp(63): error C2039: 'type' : is not a member of 'boost::mpl::eval_if_c<C,F1,F2>' 7> with 7> [ 7> C=true, 7> F1=boost::range_const_iterator<VSeeClient_list>, 7> F2=boost::range_mutable_iterator<const type> 7> ] 7> E:\boost_1_47\boost/foreach.hpp(670) : see reference to class template instantiation 'boost::range_iterator<C>' being compiled 7> with 7> [ 7> C=const type 7> ] 7> AutoPerformance\APSystem.cpp(224) : see reference to function template instantiation 'boost::foreach_detail_::auto_any<T> boost::foreach_detail_::begin<VSeeClient_list,boost::mpl::false_>(boost::foreach_detail_::auto_any_t,boost::foreach_detail_::type2type<VSeeClient_list,C> *,boost::mpl::false_ *)' being compiled 7> with 7> [ 7> T=VSeeClient_list::iterator, 7> C=boost::mpl::false_ 7> ] The error points here: template< typename C > struct range_iterator { typedef BOOST_RANGE_DEDUCED_TYPENAME mpl::eval_if_c< is_const<C>::value, range_const_iterator< typename remove_const<C>::type >, range_mutable_iterator<C> >::type type; }; Now a little looking through the manual tells me that mpl::eval_if_c::type will be one of the two metafunctions, so it should not disappear completely. I don't believe I missed anything from the iterator code: the Value type is given as the 3rd template argument to the iterator_adaptor, so that should set up any metafunctions needed to find the iterator's type, right? I'm compiling using MS Visual Studio 10. —John

[Graph] Help with delta_stepping_shortest_paths()
by Leo Hidd 11 Mar '12

11 Mar '12

Hi all, I'm having a hard time trying to use the distributed SSSP algorithm delta_stepping_shortest_paths. I found this example http://code.google.com/p/boost-doc-zh/source/browse/trunk/libs/graph_parall… but it compiles with error in line 192: 'boost::property_map<Graph,Property>' : more than one partial specialization matches the template argument list (MS Visual Studio 2008, MPI from Microsoft HPC Pack 2008 R2, Boost 1.48) Do anyone have any suggestion, or any other example? thx for your time, leo

Trouble with template on boost::function and boost::bind
by pwx 11 Mar '12

11 Mar '12

I tried to create a template function that receives boost::function as parameter. Say like this: template <typename T1, typename T2> void proc(const boost::function<void(const T1&, T2&)> &p) { // ... } void f(const string& s1, string&s2) { // ... } Everything goes ok when I called proc( boost::function<void(const string&, string&)>(f) ). But when I try this: proc(boost::bind(f, _1, _2)); The compiler refused with the error: no matching function for call to ‘proc(boost::_bi::bind_t<boost::_bi::unspecified, F, boost::_bi::list2<boost::arg<1>, boost::arg<2> > >)’ Anyway to fulfill this design purpose? Thanks.

Boost interprocess containers - performance issue
by Naveen Santhapuri 11 Mar '12

11 Mar '12

Hello all, I am experimenting with Boost interprocess containers and like the ease of using them. I want to use these in place of the "linux shared memory+shared memory allocator + std containers". However, I am seeing some performance hit when using boost. I measured the times for vector access from shared memory. I define access as indexing into the vector (v[i]) (all times in milli seconds): Num elements Local heap | Boost ipc | Shmat() 100,000 0.23 0.39 0.27 1,000,000 2.3 3.85 2.7 I repeated these for different number of elements and the results scaled as above. I used callgrid+kcachegrind to profile boost and shmat() access, and I see there is a significant amount of time spent in boost offset pointer calculation and mcount ( I don't know what that is). Is there something I am missing or is this an expected performance hit, for using boost with all off the additional functionality, compared to linux shared memory? Thank you, Naveen

Re: [Boost-users] Identify cycles in a undirected graph
by ddboy40 09 Mar '12

09 Mar '12

Sorry for the Doble posting, wast'nt yet register to the mailing list. Cheers! hi Folks, I've played around with the following example: struct detect_loops : public boost::dfs_visitor<> { template <class Edge, class Graph> void back_edge(Edge e, const Graph& g) { std::cout << source(e, g) << " -- " << target(e, g) << "\n"; } }; int main(int,char*[]) { typedef std::pair<int,int> Edge; std::vector<Edge> edges; edges.push_back(Edge(0,1)); edges.push_back(Edge(1,2)); edges.push_back(Edge(2,3)); edges.push_back(Edge(3,1)); edges.push_back(Edge(4,5)); edges.push_back(Edge(5,0)); edges.push_back(Edge(4,0)); edges.push_back(Edge(5,6)); edges.push_back(Edge(2,6)); typedef adjacency_list< vecS, vecS, undirectedS, no_property, property<edge_color_t, default_color_type> > graph_t; typedef graph_traits<graph_t>::vertex_descriptor vertex_t; graph_t g(edges.begin(), edges.end(), 7); std::cout << "back edges:\n"; detect_loops vis; undirected_dfs(g, root_vertex(vertex_t(0)).visitor(vis).edge_color_map(get(edge_color, g))); std::cout << std::endl; return 0; } However, I donot know how and where to place the predeccesor recorder. Secondly, I actually need but all the cycles, i.e. these may not have only distinct verterces. i.e some vertices may occur repeated in certain circles. My example above has 3 distinct cycles I guess and thats wha t the the back_edge() gives. But, I'll like to have all the hamiltonian cycles (hope they call it like that ;)). Thanks in advance for the tipps.

iter and reverse_iter
by MM 09 Mar '12

09 Mar '12

Hello, As much as .end() returns an iterator pointing to the element past last of a std container, and rend() a reverse iter pointing to the element before first of a container, is there a way to have 1 object that points to "before first", a value in the container, and "after last" in 1 go? MM
