I can't, for whatever reason. I've been told that exec-success "gets in" very late in the game. I was able to trace dynamic library loading and intialization with dtrace -c, something I'm not able to do with exec-success either. Can you? This email sent to site_archiver(a)lists.apple.com

This might help if you haven't seen it: <http://blogs.sun.com/dap/entry/writing_a_dtrace_usdt_provider > This could just be an issue of making sure that dtrace has learned about your provider by the time it parses the probe definition.

dtrace and missing a good chunk of startup time

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… I seem to be missing a good chunk of startup time with my reworked approach. I used to be able to stop tracing Safari once NSApplicationMain was entered. This was with 'dtrace -c...'. I'm no longer able to do so with exec-success, stop and attaching to the stopped process, e.g. END { this->total = timestamp - start; printf("Total: %u.%06ums\n", this->total / 1000000, this->total % 1000000); } Any suggestions on how to fix this? There must be some kind of a race between dtrace probes and Safari, as it's being awaken with 'kill - CONT'. This email sent to site_archiver(a)lists.apple.com
