- * js_objgc.d - trace JavaScript Object GC using DTrace.
- * Written for the JavaScript DTrace provider.
- *
- * $Id: js_objgc.d 63 2007-10-04 04:34:38Z brendan $
- *
- * This traces JavaScript activity from all running browers on the system
- * which support the JavaScript DTrace provider.
- *
- * USAGE: js_objgc.d # hit Ctrl-C to end
- *
- * FIELDS:
- * FILE Filename that contained the function
- * CLASS Class to which this new object belongs
- * TOTAL Object entropy (positive == uncollected)
- *
- * This script provides information on which objects are not being garbage
- * collected, an issue which causes the browser to steadily leak memory.
- * We trace object creation (+1) and destruction (-1), and provide a
- * summary each second of the running tally of the object class and
- * originating filename. If over the period of several minutes an object
- * type is still steadily increasing, then that would be of interest.
- * Be patient, depending on the rate of object creation it can take over
- * ten minutes for garbage collect to kick in.
- *
- * NOTES:
- * - it is possible that you will see negative entropy. That happens
- * when you begin tracing after some objects have already been created,
- * and then trace their destruction.
- * - there are other Things that GC handles, other than Objects; extra
- * probes can be added to trace them, should the need arise.
