A user reported some debugging code that had been left in Boost.Graph for a couple of releases. It is a simple patch and a really embarrassing bug to leave in. It is change 59005 in trunk: Index: read_graphviz_new.cpp =================================================================== --- read_graphviz_new.cpp (revision 59004) +++ read_graphviz_new.cpp (revision 59005) @@ -764,7 +764,7 @@ typedef boost::detail::graph::node_t vertex; typedef boost::detail::graph::edge_t edge; for (std::map<node_name, properties>::const_iterator i = r.nodes.begin(); i != r.nodes.end(); ++i) { - std::cerr << i->first << " " << props_to_string(i->second) << std::endl; + // std::cerr << i->first << " " << props_to_string(i->second) << std::endl; mg->do_add_vertex(i->first); for (properties::const_iterator j = i->second.begin(); j != i->second.end(); ++j) { mg->set_node_property(j->first, i->first, j->second); @@ -772,7 +772,7 @@ } for (std::vector<edge_info>::const_iterator i = r.edges.begin(); i != r.edges.end(); ++i) { const edge_info& ei = *i; - std::cerr << ei.source << " -> " << ei.target << " " << props_to_string(ei.props) << std::endl; + // std::cerr << ei.source << " -> " << ei.target << " " << props_to_string(ei.props) << std::endl; edge e = edge::new_edge(); mg->do_add_edge(e, ei.source.name, ei.target.name); for (properties::const_iterator j = ei.props.begin(); j != ei.props.end(); ++j) { @@ -782,7 +782,7 @@ std::map<subgraph_name, properties>::const_iterator root_graph_props_i = r.graph_props.find("___root___"); assert (root_graph_props_i != r.graph_props.end()); // Should not happen const properties& root_graph_props = root_graph_props_i->second; - std::cerr << "ending graph " << props_to_string(root_graph_props) << std::endl; + // std::cerr << "ending graph " << props_to_string(root_graph_props) << std::endl; for (properties::const_iterator i = root_graph_props.begin(); i != root_graph_props.end(); ++i) { mg->set_graph_property(i->first, i->second); } May I please put this into the release branch for 1.42?
