WL#3015: Logging Improvements – No Restarts(ver N3)
Added slow_query_log & general_log global upadatable variables.
Added slow-query-log & general-log startup options.
Added log_output, log_path, log_slow_queries_path global updatable variables.

Now we can do things like “SET GLOBAL general_log = ON;” and “SET GLOBAL log_path=’/log/tmp.log’;”.
This has been something long requested so it’s great to see this slip in to the tree in time for 5.1!
This is such good news, how many times having this would have helped me out in a pinch.
