From e137d3e0cc26fa9bd0abf9c93f273405d3262454 Mon Sep 17 00:00:00 2001 From: christos Date: Wed, 30 Sep 2015 22:01:06 +0000 Subject: Import the dtrace toolkit from FreeBSD; simple scripts such as dtruss work unmodified. For others we'll need to add the missing probes and adjust. This is not attached to the build. --- .../cddl/dtracetoolkit/dist/JavaScript/js_execs.d | 51 ++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100755 external/cddl/dtracetoolkit/dist/JavaScript/js_execs.d (limited to 'external/cddl/dtracetoolkit/dist/JavaScript/js_execs.d') diff --git a/external/cddl/dtracetoolkit/dist/JavaScript/js_execs.d b/external/cddl/dtracetoolkit/dist/JavaScript/js_execs.d new file mode 100755 index 00000000000..7c691f50633 --- /dev/null +++ b/external/cddl/dtracetoolkit/dist/JavaScript/js_execs.d @@ -0,0 +1,51 @@ +#!/usr/sbin/dtrace -Zs +/* + * js_execs.d - JavaScript execute snoop using DTrace. + * Written for the JavaScript DTrace provider. + * + * $Id: js_execs.d,v 1.1.1.1 2015/09/30 22:01:09 christos Exp $ + * + * This traces activity from all browsers on the system that are + * running with JavaScript provider support. + * + * USAGE: js_execs.d # hit Ctrl-C to end + * + * FIELDS: + * TIME Time of event + * FILE Filename of the JavaScript program + * LINENO Line number in filename + * + * Filename and function names are printed if available. + * + * COPYRIGHT: Copyright (c) 2007 Brendan Gregg. + * + * CDDL HEADER START + * + * The contents of this file are subject to the terms of the + * Common Development and Distribution License, Version 1.0 only + * (the "License").
