From: Jürgen Doser Date: Fri, 1 Feb 2013 14:50:33 +0000 (+0100) Subject: Remove use of operator[] on a std::map, so no spurious elements get inserted. (fixes... X-Git-Url: http://81.2.79.47:8989/gitweb/?a=commitdiff_plain;h=9ebf1fd3b7aa84cad2824906c336ea678433a3f4;p=zefram%2Fminetest%2Fminetest_engine.git Remove use of operator[] on a std::map, so no spurious elements get inserted. (fixes #464) All uses of operator[] in guiConfigureWorld.cpp have been replaced with .find() operations. In some places, operator[] had been called with mod names of "Add-Ons" or "N/A", which would insert a default-constructed ModSpec into the list of add-on mods. In other places, the use of operator[] was safe now, but it probably is safer for future changes to use .find() everywhere. --- diff --git a/src/guiConfigureWorld.cpp b/src/guiConfigureWorld.cpp index 38f1a554..fdcd0d3e 100644 --- a/src/guiConfigureWorld.cpp +++ b/src/guiConfigureWorld.cpp @@ -414,8 +414,9 @@ bool GUIConfigureWorld::OnEvent(const SEvent& event) else if(selected_node != NULL && selected_node->getText() != NULL) { std::string modname = wide_to_narrow(selected_node->getText());
