Last change on this file since 2732 was 2344, checked in by rgrieder, 16 years ago

Completed destruction of static elements like XMLPort, Identifier, etc.
Of initially about 250 memory leaks (not in the actual meaning but the memory was never freed anyway) only 1 remains in TinyCpp.

  • Core class is now a normal Singleton that gets created and destroyed in main.
  • The same goes for Language, LuaBind, SignalHandler and PlayerManager.
  • Added a new std::set to the CommandExecutor so that the external ConsoleCommands can get destroyed too.
  • Code for destroying CommandLineArguments
  • Added destruction code for ConstructionCallbacks in Identifier
  • Moved internal identifier map (the one with the typeid(.) names) in a static function in Identifier. This was necessary in order to destroy ALL Identifiers with the static destruction function. Before it was possible to create an Identifier with having a class instance (that would call RegisterObject) for instance by simply accessing it via getIdentifier.
  • Removed a big memory leak in Button (forgot to destroy the ConfigValueContainers)
  • Added destruction code for InputBufferListenerTuples in InputBuffer destructor.
  • Added destruction code for load and save executors in both XMLPortParam and XMLPortObject
  • Added destruction code for ConsoleCommands in GSRoot, GSGraphics and GSLevel (temporary solution anyway)
  • Deleting the CEGUILua script module seems to work properly now, one memory leak less (GUIManager.cc)
  • Added global destruction calls in Main.cc
  • Property svn:eol-style set to native
  • Property svn:mergeinfo set to (toggle deleted branches)
