The linux-kernel mailing list had examples of this occurring in real life too. In real C programs function signatures usually end up being the unique lines which is what you want but it can happen that surprising lines are unique. Even braces can be unique if a given indentation level is only used once. The discussion basically convinced me that using uniqueness alone is a bad idea but that the basic idea of trying to identify the important lines is a fine idea. It's just that uniqueness turns out to be a relatively weak signal for interesting lines. Linus suggested line-length but it's pretty debatable which is better. -- greg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
