[regex] Generate matching string
by Roland Bock 14 Jan '10

14 Jan '10

Hi, given a regex, is there a way to create sample strings which would match? Of course, for many patterns, the number of possible strings would be practically infinite. But sometimes it would be helpful to have even one sample of a matching string. Any ideas? Thanks and regards, Roland

asio: selective cancellation of reads/writes
by Alexander Fritze 14 Jan '10

14 Jan '10

Hi, In asio, if I have a socket with pending asynchronous reads and writes, is there a way to selectively cancel only the reads or only the writes? All I can find is basic_stream_socket::cancel() which closes *all* pending operations on the socket. Thanks for any help, Alex

trouble with spirit (boost 1.39)
by Noah Roberts 13 Jan '10

13 Jan '10

void read_formula_line(esi::string_t const& line, table_fluid_data & data) { namespace sp = boost::spirit::classic; using namespace sp; unsigned int index = 0; parse_info<wchar_t const*> info = sp::parse(line.c_str(), // begin grammar ( L'P' >> uint_p[assign_a(index)] //>> uint_p[assign_a(data.formulas[index-1].formula_id)] >> uint_p[boost::bind(&assign_i, _1, boost::ref(data.formulas [index-1].formula_id))] >> real_p[boost::bind(&assign_dbl, _1, boost::ref(data.formulas [index-1].coefficients[0]))] //>> real_p[assign_a(data.formulas[index-1].coefficients[0])] >> real_p[assign_a(data.formulas[index-1].coefficients[1])] >> real_p[assign_a(data.formulas[index-1].coefficients[2])] >> real_p[assign_a(data.formulas[index-1].coefficients[3])] >> real_p[assign_a(data.formulas[index-1].coefficients[4])] >> lexeme_d[*space_p] // necessary to clip off the last bit. ) , space_p); if (!info.full) throw std::runtime_error("Parse fail in formula line."); } The line is being parsed by the above code but the values are not being assigned by the assign_a nor by the boost::bind call to my own val = x setters. The setters are being called correctly, but the data is not getting through for some reason. It's like the data structure is being copied instead of referenced but I'm explicitely using references. Any idea what gives?

Building 1.41 for win64 with python
by Tom Kent 13 Jan '10

13 Jan '10

I googled around for this, but didn't find any answers. I'm building 64 bit libraries for visual studio on a 32 bit win XP box and getting the attached linker errors. I get similar results with visual studio 8 and 9. Any thoughts?

hello, I use boost1.40.0 on linux2.6/gcc4.1.2. when my process execute code as flow, my process crash.: void CSapConnection::HandleWrite(const boost::system::error_code& err) { std::cout<<"error:" <<err.message()<<"\n"; } This coredump information: Program terminated with signal 11, Segmentation fault. #0 0x080c7c83 in boost::system::error_code::message (this=0xb6bf0f64) at /usr/local/boost_1_40_0/boost/system/error_code.hpp:347 347 std::string message() const { return m_cat->message(value()); } (gdb) p this $1 = (const boost::system::error_code * const) 0xb6bf0f64 (gdb) p *this $2 = {m_val = 136236300, m_cat = 0xd56658} (gdb) p *m_cat $3 = {<boost::noncopyable_::noncopyable> = {<No data fields>}, _vptr.error_category = 0x0} Is this a bug of asio??

Boost-users] [asio]about reactor_op_queue dead loop
by victor 13 Jan '10

13 Jan '10

I call boost::asio::async_write, finally it call "bool enqueue_operation(Descriptor descriptor, Operation operation)" In this function , there is code as flow: while (current_op->next_) current_op = current_op->next_; My process execute it for ever. Using gdb to attach the prcocess, I find : 68 while (current_op->next_) (gdb) p current_op $8 = (class boost::asio::detail::reactor_op_queue<int>::op_base *) 0x93381c8 (gdb) p current_op->next_ $9 = (class boost::asio::detail::reactor_op_queue<int>::op_base *) 0x93381c8 current_op and current_op->next_ is the same address. how did it come true? I have no any clue. Anyone can offer some suggestion?

Newbie question: Serialization of an Array2D --> Cell** m_cells
by Simon Ruffieux 13 Jan '10

13 Jan '10

Hello ! I am trying to serialize a a complex structure. One of the "variable" is a 2D Array (Cell** m_cells ) declared with pointers. I need to keep this data structure as it is. I have read some stuff about multi array with boost but found nothing to serialize my Cell** m_cells. Maybe one of you has the solution .... Note1: using boost 1.41.0, g++ and ubuntu 9.04 .... Note2: As you may understand while reading the code, I have in fact an Array2D of PointAccumulator .... (Cell = PointAccumulator) The part of code that is not correct ..... * template <class Archive> void serialize(Archive& ar, const unsigned int version){ *ar & m_xsize & m_ysize &* m_cells; }* And raising this error: wheelchair@wheelchair-laptop:~/playerstage/boostTest$ g++ -I/usr/local/include/ -L/usr/local/lib/ simple2.cpp -o simple -lboost_serialization /usr/local/include/boost/serialization/access.hpp: In static member function ‘static void boost::serialization::access::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::text_iarchive, T = PointAccumulator*]’: /usr/local/include/boost/serialization/serialization.hpp:74: instantiated from ‘void boost::serialization::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::text_iarchive, T = PointAccumulator*]’ /usr/local/include/boost/serialization/serialization.hpp:133: instantiated from ‘void boost::serialization::serialize_adl(Archive&, T&, unsigned int) [with Archive = boost::archive::text_iarchive, T = PointAccumulator*]’ /usr/local/include/boost/archive/detail/iserializer.hpp:173: instantiated from ‘void boost::archive::detail::iserializer<Archive, T>::load_object_data(boost::archive::detail::basic_iarchive&, void*, unsigned int) const [with Archive = boost::archive::text_iarchive, T = PointAccumulator*]’ simple2.cpp:186: instantiated from here /usr/local/include/boost/serialization/access.hpp:109: error: request for member ‘serialize’ in ‘t’, which is of non-class type ‘PointAccumulator*’ /usr/local/include/boost/serialization/access.hpp: In static member function ‘static void boost::serialization::access::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::text_oarchive, T = PointAccumulator*]’: /usr/local/include/boost/serialization/serialization.hpp:74: instantiated from ‘void boost::serialization::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::text_oarchive, T = PointAccumulator*]’ /usr/local/include/boost/serialization/serialization.hpp:133: instantiated from ‘void boost::serialization::serialize_adl(Archive&, T&, unsigned int) [with Archive = boost::archive::text_oarchive, T = PointAccumulator*]’ /usr/local/include/boost/archive/detail/oserializer.hpp:139: instantiated from ‘void boost::archive::detail::oserializer<Archive, T>::save_object_data(boost::archive::detail::basic_oarchive&, const void*) const [with Archive = boost::archive::text_oarchive, T = PointAccumulator*]’ simple2.cpp:186: instantiated from here /usr/local/include/boost/serialization/access.hpp:109: error: request for member ‘serialize’ in ‘t’, which is of non-class type ‘PointAccumulator*’ Here is the code I use for my tests: #include <iostream> #include <iterator> #include <algorithm> #include <sstream> #include <fstream> #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> using namespace std;

newbie question --> invalid application of ?sizeof? to incomplete type ?boost::STATIC_ASSERTION_FAILURE<false>?
by Simon Ruffieux 13 Jan '10

13 Jan '10

Hello ! I am a newbie to Boost ... and trying to use it in order to serialize a complex data structure for one of my project. (the struct particle) You can see the nested data structure at the end of this file. I have started from the 'leafs' and yet trying to serialize a point which is a variable of a PointAccumulator. You can see the point.h file below. Here is the test code I am using to try to serialize it. Note that I read a few succinct tutorials and already succesfully compiled some simple examples. ... GMapping::point<int>p = GMapping::point<int>(); //saveIntoFile<text_oarchive>(particlesSaved[1].map.cell(1,1).acc, "outTest.txt"); saveIntoFile<text_oarchive>(p, "outTest.txt"); ... template <class T> void RobotController::saveIntoFile(GMapping::point<int>& p, const char* file){ std::ofstream ofile(file); T ar(ofile); ar << p; ofile.close(); } However when compiling; it raises the following error: ... /usr/include/boost/archive/detail/oserializer.hpp: In function ‘void boost::archive::save(Archive&, T&) [with Archive = boost::archive::text_oarchive, T = GMapping::point<int>]’: /usr/include/boost/archive/detail/common_oarchive.hpp:64: instantiated from ‘void boost::archive::detail::common_oarchive<Archive>::save_override(T&, int) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/basic_text_oarchive.hpp:75: instantiated from ‘void boost::archive::basic_text_oarchive<Archive>::save_override(T&, int) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/detail/interface_oarchive.hpp:64: instantiated from ‘Archive& boost::archive::detail::interface_oarchive<Archive>::operator<<(T&) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ RobotController.cpp:186: instantiated from ‘void RobotController::saveIntoFile(GMapping::point<int>, const char*) [with T = boost::archive::text_oarchive]’ RobotController.cpp:223: instantiated from here /usr/include/boost/archive/detail/oserializer.hpp:564: error: invalid application of ‘sizeof’ to incomplete type ‘boost::STATIC_ASSERTION_FAILURE<false>’ /usr/include/boost/archive/detail/common_oarchive.hpp:64: instantiated from ‘void boost::archive::detail::common_oarchive<Archive>::save_override(T&, int) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/basic_text_oarchive.hpp:75: instantiated from ‘void boost::archive::basic_text_oarchive<Archive>::save_override(T&, int) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/detail/interface_oarchive.hpp:64: instantiated from ‘Archive& boost::archive::detail::interface_oarchive<Archive>::operator<<(T&) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ RobotController.cpp:186: instantiated from ‘void RobotController::saveIntoFile(GMapping::point<int>, const char*) [with T = boost::archive::text_oarchive]’ RobotController.cpp:223: instantiated from here /usr/include/boost/archive/detail/oserializer.hpp:564: error: invalid application of ‘sizeof’ to incomplete type ‘boost::STATIC_ASSERTION_FAILURE<false>’ make: *** [RobotController.o] Error 1 Anyone understands what is the error ?

Hi I want to write a function like that template<class A, class T0, class T1, ..., class Tn> execute(const A& a, T0& arg0, T1& arg&, .. , Tn& argn) { boost::fusion::vector<T0,...,Tn> vec(arg0, arg1, .., argn); /* rest of the code */ } Can anybody guide me how can I write this function without overloading it with different number of args? Thanks in anticipation Noman Javed

c++: boost::multi_array - in a class

Hi to all, i wrote a class (Influx), where i try to define there a boost::multi_arry occ_sign_change. Once i tried in Influx::Influx to write: occ_sign_change = vec::uint32_1d_t ( boost::extents[ num_elements ] ); i was able to compile, but at run time i got the following error: randum.rc3_64: /usr/include/boost/multi_array/multi_array_ref.hpp:487: boost::multi_array_ref<T, NumDims>& boost::multi_array_ref<T, NumDims>::operator=(const ConstMultiArray&) [with ConstMultiArray = boost::multi_array<unsigned int, 1ul, std::allocator<unsigned int> >, T = unsigned int, long unsigned int NumDims = 1ul]: Assertion `std::equal(other.shape(),other.shape()+this->num_dimensions(), this->shape())' failed. that is why i rewrote the above line as following: vec::uint32_1d_t occ_sign_change ( boost::extents[ num_elements ] ); but now, when i call for the size of occ_sign_change in Influx::Clean, i get that the size is zero. how could i solve this problem? regards #include <boost/random/uniform_01.hpp> #include <boost/random.hpp> #include "randum.rc3.hpp" namespace vec { typedef boost::multi_array< uint32_t , 1> uint32_1d_t; typedef boost::multi_array< uint32_t , 2> uint32_2d_t; typedef boost::multi_array< uint32_t , 3> uint32_3d_t; typedef boost::multi_array< uint32_t , 1> uint32_1d_t; typedef boost::multi_array< uint32_t , 2> uint32_2d_t; typedef boost::multi_array< double , 1> double_1d_t; typedef boost::multi_array< double , 2> double_2d_t; typedef uint32_1d_t::index index_t; } class Influx { public: Influx ( uint32_t num_elements , double p_, double kappa_ , vec::uint32_2d_t *Pointer_ , threshold_t threshold_ , uint32_t num_bits , uint16_t max_runs_ ); void Update (); void Validity ( const uint32_t i ); void Clean( uint32_t run ); boost::dynamic_bitset<> occupied; vec::uint32_1d_t occupied_counter; vec::uint32_1d_t num_neighbours; vec::uint32_1d_t occ_sign_change; private: std::vector< uint32_t > remove_node_v; vec::uint32_2d_t *Pointer; std::vector< uint32_t > num_neighbours_epoch; double p; double kappa; threshold_t threshold; uint16_t max_runs; uint32_t bits_mask; uint32_t complement_num; }; Influx::Influx ( uint32_t num_elements , double p_, double kappa_ , vec::uint32_2d_t *Pointer_ , threshold_t threshold_ , uint32_t num_bits , uint16_t max_runs_ ) { bits_mask = ( 1 << num_bits ) - 1; Pointer = Pointer_; p = p_; kappa = kappa_; threshold = threshold_; max_runs = max_runs_; complement_num = 0; num_neighbours_epoch = std::vector< uint32_t > ( num_elements , 0); occupied = boost::dynamic_bitset<> ( num_elements , 0 ); // all 0's by default vec::uint32_1d_t occupied_counter ( boost::extents[ num_elements ] ); vec::uint32_1d_t occ_sign_change ( boost::extents[ num_elements ] ); vec::uint32_1d_t num_neighbours ( boost::extents[ num_elements ] ); remove_node_v.reserve( num_elements ); std::fill_n( occupied_counter.begin() , occupied_counter.num_elements() , 0 ); std::fill_n( occ_sign_change.begin() , occ_sign_change.num_elements() , 0 ); std::fill_n( num_neighbours.origin() , num_neighbours.num_elements() , 0 ); } void Influx::Clean ( uint32_t run ) { for ( vec::uint32_1d_t::size_type i = 0 ; i < remove_node_v.size() ; i++ ) { occupied[ remove_node_v[i] ] = 0; if ( run >= max_runs ) { std::cout << "size occ_sign_change: " << occ_sign_change.size() << std::endl; occ_sign_change[ remove_node_v[i] ]++; } } remove_node_v.clear(); }
