Gregorian 1.32 still has VC71 warnings like 1.31
by jkharris7＠comcast.net 23 Nov '04

Do I have some incorrect options here? I would've thought these would go away, but they were the same in 1.31. I can't find others reporting the same warnings.

IMPORTANT: yahoogroups admin rights problem
by Toon Knapen 23 Nov '04

23 Nov '04

Hello ALL, As many of you might know, currently we are unable to add new members to the ublas-ml. The problem is that only Joerg has the rights to add members to the list but Joerg does not respond anymore. Could some of you try to contact Joerg or give me his telephone number that I talk to him about this. If we do not have a solution by end of November I will create a new project on yahoogroups (and we all have to switch). Additionally we need to contact Joerg and Mathias (again!) about applying the Boost Software License. I currently have the impression that they are not willing to change ublas to the BSL. In that case IMO, we will have to rewrite uBLAS to not get thrown out of boost. Again his phone-number would be handy if you have it available. Please contact the ml or me asap about the above issues or we will need to take drastic actions. toon

Memory leak reported using threads library
by gast128 23 Nov '04

23 Nov '04

Dear all, Downloading and using the 1.32 version was probably not such a good idea... Now I get a mem-leak reported by the debug crt of VC 7.1. The report is located in 'init_threadmon_mutex' where a global object is allocated but never deleted. Before we start a discussion of what is a memory leak or not, in our production code we do not accept any leak reported by VC. The past has learned us that if you accept one leak, programmers/colleaques start to ignore them and in the end you have 200 leaks, instead of this one. I guess it wouldn't be difficult to resolve this one, on process exit it can be deallocated. And yes I am aware of the (phoenix) singleton discussions in Alexandrescu/Meyers, but really this kind of reinit of singletons after atexit calls won't happen too much. Wkr, me

difference between .output and .run files

After bjam is executed, both .output and .run files are executed. However, they are the same in content. Why not just use one file, why need both .output and .run files? ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca

dijkstra_shortest_paths performance problem
by Gustavo Sÿffffe1nchez 23 Nov '04

23 Nov '04

Hello, all We are doing a algorithm based on the graph boost library. Actually, it will be a Dinamic Link Library(dll). Our problem is when we execute it in console mode, it costs 12 seconds to finish, while it costs 120 seconds more or less when we are calling it as a DLL from Visual Basic. We have traced into the source code and found that is the dijkstra_shortest_paths function from the boost library which costs us 10 times more in the dll than the console mode. We call the dijkstra_shortest_paths like this: dijkstra_shortest_paths(g,s,predecessor_map(&p[0]).distance_map(&d[0]). visitor(make_dijkstra_visitor(_buscaVia(g,on_finish_vertex(),vinfo,edge_comp,via,p) ))); ///////below is the codes for visitor template <class Graph, class Tag> struct buscaVia : public boost::base_visitor<buscaVia<Graph, Tag> > { typedef Tag event_filter; buscaVia(typename property_map<Graph, vertex_info_t>::type & vinfo_, property_map<UGraph, edge_component_t>::type & ecomp,Vertex & _via,vector<Vertex> &p) :vinfo(vinfo_),encontrada(false),_ecomp(ecomp),via(_via),_p(p){} template <class Vertex, class Graph> void operator() (Vertex v, Graph& g){ bool hay_comp=false; Vertex a=v; if( vinfo[v].is_via && ! encontrada ){ while(_p[a]!=a){// mientras no hayamos llegado al origen if( _ecomp[edge(a,_p[a],g).first]->isComponentCaerTension() ){hay_comp=true; break;} else a=_p[a]; //pasamos al anterior } if(hay_comp==false){ // encontramos la via de la bobina DEBUG_CODE(cout << " via encontrada: " << vinfo[v].vertex_name << endl;) via = v; encontrada=true; } } DEBUG_CODE(else cout << "pasamos por vertice: " << vinfo[v].vertex_name << endl;) } private: typename property_map<Graph, vertex_info_t>::type & vinfo; property_map<UGraph, edge_component_t>::type & _ecomp; bool encontrada; Vertex & via; vector<Vertex> &_p; }; template<class Graph, class Tag> inline buscaVia<Graph,Tag> _buscaVia(Graph &g, Tag,typename property_map<Graph, vertex_info_t>::type & vinfo, property_map<UGraph, edge_component_t>::type & ecomp, Vertex & _via, vector<Vertex> &p){ return buscaVia<Graph,Tag>(vinfo,ecomp,_via,p); } ///////end of codes for visitor We appreciate your kind help!

newbie: Graph library - bundled properties
by TC MA 23 Nov '04

23 Nov '04

I try to use the Boost Graph library bundled properties which is introduced in 1.32.0. I modify the sample program libs/graph/example/graph_property.cpp which then fail to compile, I don't know enough about bundled properties to fix it. Please help. Thanks. I use gcc version 3.4.2 (Gentoo Linux 3.4.2-r2, ssp-3.4.1-1, pie-8.7.6.5). graph_property.cpp source code is: int main() { using namespace boost; using std::string; struct edgeStruct { int weight; };

*vertices(graph_t).first; graph_t::edge_descriptor e = *out_edges(v, graph_t).first; g[e].weight = 1; std::cout << "name: " << get_property(g, graph_name) << std::endl; typedef subgraph<graph_t> subgraph_t; subgraph_t sg; get_property(sg, graph_name) = "subgraph"; std::cout << "name: " << get_property(sg, graph_name) << std::endl; return exit_success; } //compile output is: gcc-C++-action

As of the upcoming release, the Boost signals library does make a guarantee of the order of signals within a particular group. The order within a particular group is FIFO.

Hi Roland In order to clear random influences from other areas of the software i'm working on, I have created a simple program with the code that i listed before. nothing else, no tls code. The intentinal leak would be harmless if it did not keep increasing. If I let the program run for long enough i will run out of memory. Sorry which messages would you like me to post? Haven't tracked down the leak yet. My problem is solved for the time being by using msvcrt71.dll as i said before. However it would be nice to be able to using the static lib. I replace the code in the loop which constantly starts and stop threads with my own code that did the same thing. This code was pretty much the same as the code for boost::thread using the windows api functions. This did not leak. However the big difference between my code and boost::thread is that my code didn't use boost::function. Therefore I suspect the leak could be in there! Looking at function it certainly isn't as trivial as thread. One thing i have noticed is that there is an option to get function to use "new" instead of std::allocator with the macro BOOST_NO_STD_ALLOCATOR. (function_template.hpp). I haven't got round to trying this yet though. Alan
