This PyGTK bug is going to be important for OLPC as it might slow down object destruction.
http://bugzilla.gnome.org/show_bug.cgi?id=320428 For example in the tinymail-python-test.py*, you will find a gc.collect(). This is to speed up the destruction of objects in the situation described in Bug #320428 https://svn.tinymail.org/svn/tinymail/trunk/libtinymail-test/tinymail-python-test.py In case of tinymail the GtkTreeModel that holds a reference on all the headers of the current folder, is such an object. model = MsgHeaderListModel () treeview.set_model (model) newmodel = MsgHeaderListModel () treeview.set_model (newmodel) Will not immediately mark "model" for garbage collection (when model goes out of scope). Adding a gc.collect(), however, will. That model instance, in case of tinymail, holds a reference to the headers of your folder. This is where most of the memory tinymail consumes is located (the summary information). Therefore it's a small disaster on a device with few memory resources, that Pythons garbage collector is slow at detecting this. Applying the patch of Bug #320428 or performing gc.collect() in your Python code fixes this. Note that tinymail isn't going to be the only case. -- Philip Van Hoof, software developer at x-tend home: me at pvanhoof dot be gnome: pvanhoof at gnome dot org work: vanhoof at x-tend dot be http://www.pvanhoof.be - http://www.x-tend.be _______________________________________________ Sugar mailing list [email protected] http://mailman.laptop.org/mailman/listinfo/sugar
