Hi, I'm trying to have my application run under both python2 and 3, and I'm having a surprising problem.
I have a gtk.ListStore with a column that has to hold integers between 2^32 and 2^64, what would be long's in python2. If I build it with gtk.ListStore(int, ...) in python3 my int's get chopped to 32bits, which is pretty surprising, because in python2 a ListStore(long,...) does the correct thing. So I used GObject.TYPE_UINT64 and I can add rows with ls.append(big_integer_value) in both versions. The problem is that it's pretty slow, so I dug .insert_with_valuesv(-1,[0,...], [big_integer_value,...]) from the API. On python2, this is perfectly fine, I give it a long, and in the ListStore I get a guint64 with the right value. On python3, I give an int (between 2^32 and 2^64) and in the ListStore I get a guint64 truncated at 32bit, which is BAD, and definitely not what I expected. I can get around this with an explicit cast: Object.Value(GObject.TYPE_UINT64, addr) but this way I lose all the speed I gained, while python2 manages to do the right thing without any expensive cast. Did I get something wrong? Thanks. _______________________________________________ python-hackers-list mailing list python-hackers-list@gnome.org https://mail.gnome.org/mailman/listinfo/python-hackers-list
