I just noticed the code removes *all* PUT opcodes, regardless if they are needed or not. So, this code can only be used if there's no GET in the stream (which is unlikely for a large stream). I believe Collin made this trade-off for performance reasons. However, it wouldn't be hard to make the current code to work like pickletools.optimize(). -- Alexandre _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
