Iterators and algorithms
by Jiri Palecek 31 Jan '06

31 Jan '06

Hello, I have recently tried to implement merging of more lists (or union of more sets). The (somewhat silly) approach would be set<X> ret,ret2; for(list<set<X> >::iterator it=sets.begin(),end=sets.end();it!=end;++it) { set_union(ret.begin(),ret.end(),it->begin(),it->end(),inserter(ret2)); ret.clear(); swap(ret,ret2); } and ret is the result. However, it seems to me that these temporaries are unnecessary. So I wonder wheter there could/should be some class of iterators that implemented some STL algorithms. There is already an iterator that could replace the unary version of transform (transform_iterator) In my case, I'm talking about some merge_iterator that would merge two sorted sequences (being an input iterator). That is, copy(merger(a.begin(),a.end(),b.begin(),b.end()),ostream_iterator(cout)) would be equivalent to merge(a.begin(),a.end(),b.begin(),b.end(),ostream_iterator(cout)) and similarly for set_union etc. Is it possible to have such iterators?

Re: [Boost-users] Spawning a thread on a member function

Ok, I am using VC++ 6, SP5. The class has a member function void CDailyReportTree::foo() { } I am trying to spawn a thread from void CDailyReportTree::DrawHistoryTree(HTREEITEM item, const set<pair<string, string>, comp<string, string> >& nodes, const CString& filename) { map<string, pair<CString, HTREEITEM>, comp<string, pair<CString, HTREEITEM> > > localMap; for (set<pair<string, string>, comp<string, string> >::const_iterator i_ptr=nodes.begin(); i_ptr!=nodes.end(); ++i_ptr) { HTREEITEM reportItem = InsertItem(TVIF_IMAGE|TVIF_TEXT|TVIF_SELECTEDIMAGE, i_ptr->first.c_str(), 7,8, TVIS_BOLD, TVIF_TEXT, 0, item, item); localMap.insert(make_pair(i_ptr->first, make_pair(i_ptr->second.c_str(), reportItem))); } boost::bind(foo, this); } And I am getting lots of errors. Can anyone help?

boost bind logical operators question
by gast128 31 Jan '06

31 Jan '06

Dear all, this new boost bind logical operators is a great enhancement for readability of bind constructions. However I have not found out yet how to deal with e.g. built in types: std::vector<int> vec; std::list<int> lst; //copy_if does not exist in std, I know. std::copy_if(vec.begin(), vec.end(), std::back_inserter(lst), ...); this ... must now boost::bind(std::equal_to<int>(), _1, nNumber), which is quite unreadable, but no such thing like boost::bind::_1 == nNumber (like boost::lambda)? Wkr, me

lexical_cast memory consuption with VC8
by Josue Gomes 31 Jan '06

31 Jan '06

Hi, I'm experiencing a memory leak while using lexical_cast with VC8. The leak was detected by an end-user in a long-running application and evidenced with GlowCode (a leak detection tool). The origin seems to be an allocation inside ios_base (<xiosbase>). Source code for the test: #include <string> #include <boost/lexical_cast.hpp> int main() { std::string s = "1234"; unsigned u = boost::lexical_cast<unsigned>(s); } GlowCode trace: Handle 0x1555308 (0x1555308 = HeapAlloc( 0x310000, 0x0, 40)) caller(1): malloc_base(); + 236 bytes; module MSVCR80D.dll; 0x1024DB9C caller(2): malloc_dbg(); + 725 bytes; module MSVCR80D.dll; 0x1020FAA5 caller(3): malloc_dbg(); + 105 bytes; module MSVCR80D.dll; 0x1020F839 caller(4): malloc_dbg(); + 31 bytes; module MSVCR80D.dll; 0x1020F7EF caller(5): operator new(); + 30 bytes; module MSVCP80D.dll; 0x104F938E caller(6): std::ios_base::_Init(); + 112 bytes; module MSVCP80D.dll; 0x104877B0 caller(7): std::basic_ios<char,std::char_traits<char> >::init(); + 15 bytes; module MSVCP80D.dll; 0x10497CFF caller(8): std::basic_istream<char,std::char_traits<char> >::basic_istream<char,std::char_traits<char> >(); + 143 bytes; module MSVCP80D.dll; 0x10497F1F caller(9): std::basic_iostream<char,std::char_traits<char> >::basic_iostream<char,std::char_traits<char> >(); + 115 bytes; module MSVCP80D.dll; 0x104C9693 caller(10): std::basic_stringstream<char,std::char_traits<char>,std::allocator<char> >::basic_stringstream<char,std::char_traits<char>,std::allocator<char> >(); + 116 bytes; module MSVCP80D.dll; 0x104CD2A4 caller(11): boost::detail::lexical_stream<unsigned int,std::basic_string<char,std::char_traits<char>,std::allocator<char> > >::lexical_stream<unsigned int,std::basic_string<char,std::char_traits<char>,std::allocator<char> > >(); file e:\projects\libraries\boost_1_33_1\boost\lexical_cast.hpp; line 134 + 81 bytes; module mleak.exe; 0x411A41 caller(12): boost::lexical_cast<unsigned int,std::basic_string<char,std::char_traits<char>,std::allocator<char> > >(); file e:\projects\libraries\boost_1_33_1\boost\lexical_cast.hpp; line 219 + 11 bytes; module mleak.exe; 0x4116BF caller(13): main(); file e:\projects\mleak\mleak.cpp; line 7 + 9 bytes; module mleak.exe; 0x41159E caller(14): __tmainCRTStartup(); file f:\rtm\vctools\crt_bld\self_x86\crt\src\crtexe.c; line 586 + 25 bytes; module mleak.exe; 0x412EA6 caller(15): mainCRTStartup(); file f:\rtm\vctools\crt_bld\self_x86\crt\src\crtexe.c; line 403, module mleak.exe; 0x412CED Regards, Josue Gomes

[program_options] Bug in example and documentation
by Peter Gerell 31 Jan '06

31 Jan '06

Hi, I believe the example found in example/response_file.cpp and referenced in the documentation has a bug. In the following code fragment a temporary string object is passed as the first argument to the tokenizer constructor. This string is destroyed before the iteration over the tokens start. /Peter if (vm.count("response-file")) { // Load the file and tokenize it ifstream ifs(vm["response-file"].as<string>().c_str()); if (!ifs) { cout << "Could not open the response file\n"; return 1; } // Read the whole file into a string stringstream ss; ss << ifs.rdbuf(); // Split the file content char_separator<char> sep(" \n\r"); tokenizer<char_separator<char> > tok(ss.str(), sep); vector<string> args; copy(tok.begin(), tok.end(), back_inserter(args)); // Parse the file and store the options store(command_line_parser(args).options(desc).run(), vm); }

Request help with boost::compose to boost::bind conversion
by gdprosch＠micron.com 30 Jan '06

30 Jan '06

Let me apologize in advance for my ignorance but I have not been able to update the following code successfully in order to migrate from Boost 1_29 to 1_33. Despite reading the boost::bind documentation a few times I am failing to make the necessary connection regarding the use of _1, _2 and handling the use of DeRef in the equal function below. // Unary dereference functor (a functor that returns the value of the specified // parameter, dereferenced via operator*) // (Note: This DeRef code is included in a separate header.) template < class Ptr, class T > struct DeRef : public std::unary_function< Ptr, T > { T & operator()( Ptr & ptr ) const { return *ptr;} }; // --- // Compare LocalStringMap (a custom map container with Tag/Value pair). // A TagValue is a class that contains a tag and a value (both strings) // A TagValuePtr is a custom, dereferencable smart pointer. inline bool LocalStringMap::operator==( const LocalStringMap &that ) const { // Must be same size if( this->size() != that.size() ) { return false;} return equal( this->_list.begin(), this->_list.end(), that._list.begin(), boost::compose_f_gx_hy( equal_to< TagValue >(), DeRef< const TagValuePtr, const TagValue >(), DeRef< const TagValuePtr, const TagValue >() ) ); } Any assistance with this would be most helpful. I get the impression that I do not need to use the DeRef class the original author created given boost:bind's more capable traits identification. Here's what I have so far... return std::equal( this->_list.begin(), this->_list.end(), that._list.begin(), boost::bind<bool>( std::equal_to< TagValue >(), ???

After mulling a bit, I think this is the whole point of shared_ptr. But I am not sure how it works. Is this encapsulated in the check_delete?

Boost shared pointers and MSVC++ 6.0
by Henri Herscher 30 Jan '06

30 Jan '06

Hi, I'm making heavy use of the boost shared pointers in the open source audio recording (voip and sound devices) project I'm developing (http://www.oreka.org) The software is cross platform (Windowns/Linux) and shared pointers are created in plugins and typically destroyed in other plugins or in the main program. Under linux, I haven't had any kind of problem. On windows however, using MSVC++ 6SP6 I have observed strange crashes that happen only in the release mode. So far I think I have been able to solve that doing two things (both needed or crash !): 1. Make sure all DLLs and the main program are compiled with the same runtime (multithreaded DLL) 2. Make sure all DLLs and the main program are compiled with inline function exapansion disabled My questions: * Is this normal ? What have other people experienced ? * Will this go away if I upgrade to MSVC++ 7 ? Thanks Henri
