Hi John,
I ran my sample script through valgrind and it confirmed that the
leaked memory is what's being used for strings in error messages. I'm
including relevant parts of valgrind reports for different error
conditions, but it turned out to be leaking more memory than I thought
(1.6k per error message). Since the error is generated each time there
is a check for a non-existing field it adds up quickly as there is no
other way to check if a field is present on wxlua object or not.
I think the final error message in wxlua_wxLuaBindClass__index is
unnecessary; without it it would behave exactly as Lua method/field
calls behave in all other places:
> wx.wxTextCtrl().Absent()
[string "wx.wxTextCtrl().Absent()"]:1: attempt to call field 'Absent'
(a nil value)
> wx.wxTextCtrl():Absent()
[string "wx.wxTextCtrl():Absent()"]:1: attempt to call method 'Absent'
(a nil value)
> wx.wxTextCtrl().Absent
nil
Here is the simple patch I'm proposing:
diff --git a/wxLua/modules/wxlua/wxlbind.cpp b/wxLua/modules/wxlua/wxlbind.cpp
index 105f603..2523292 100644
--- a/wxLua/modules/wxlua/wxlbind.cpp
+++ b/wxLua/modules/wxlua/wxlbind.cpp
@@ -227,12 +227,6 @@ int LUACALL wxlua_wxLuaBindClass__index(lua_State *L)
}
}
- if (!found)
- {
- wxlua_error(L, wxString::Format(_("wxLua: Unable to call an
unknown method '%s' on a '%s' type."),
- lua2wx(name).c_str(), lua2wx(wxlClass ? wxlClass->name :
"").c_str()).c_str());
- }
-
return result;
}
This doesn't fix the leak directly, but it eliminates one of the main
cases that make the leak much more noticeable.
I'm including reports for two conditions: incorrect parameters
(wx.wxTextCtrl().DiscardEdits()) and non-string as the key
(wx.wxTextCtrl()[{}]). They follow different branches, but leak about
the same amount of memory.
Paul.
