Making the file append-only doesn't eliminate the problems with concurrent modification. You still have to specify and implement a robust cross-platform file locking system which will have to be shared by all implementations. This is really a great deal of complication to add to the interpreter(s). And, besides, it might not even work on NFS which was the motivation for your proposal :) _______________________________________________ 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
