The synchronization result of a log receiver is now a vector of four values, instead of three, where the last one reports the name. Also, an optional argument to `make-logger' provides a notification callback for each event sent to the logger. These changes enable more control over loggers and events. Suppose that you have processes A and B, and you want all log events of A to be visible to B, but not vice-versa. Furthermore, you want the log events to appear at B in the right order: if A logs an event before B, then A's event should arrive at a log receiver's before B's. Now that a log receiver gets the name associated with the original event, and now that the name can be re-sent in a `log-receiver', it's possible to give A and B separate loggers and send all of the events from A's logger to B's logger. Furthermore, you can use the notification callback so that when an event is logged in B, you can make sure that all available events from from A's logger have been transferred to B's logger. |

The Racket programming language =============================== Important executables: * DrRacket: Racket's integrated development environment (start here!). * Racket: the main command-line entry point for running racket programs and scripts. * GRacket: the GUI-mode Racket executable. * raco: Racket's command-line toolset. More Information ---------------- Racket comes with extensive documentation: use DrRacket's `Help' menu, or run `raco docs'. Also, visit us at http://racket-lang.org/ for more Racket resources.
