DTrace on Leopard: No probes specified, even when I specify probes?

I think you mean: sudo dtrace -p 2446 -n 'objc$target:NSObject:-init:entry { trace(); }.

1 As far as I know, yes. It's an open-source app I work on, not anything by Apple, and I'm not aware of zsh setting P_LNOATTACH on my own processes. – Peter Hosey Jul 28 '09 at 21:29.

In addition to what Graham said, your original statement will only find instances of NSObject, not its descendents. You could try sudo dtrace -p 2446 -n 'objc$target::-init*:entry {}' to catch all -init variants by all NSObject-derived instances.

– Peter Hosey Jul 28 '09 at 22:58 I don't think so. It's my impression that the module is always set to be the instance's class, even when it's calling a method via super. I just tried the command line I suggested with NSObject instead of a blank module and got no matching probes, while leaving the module out hits ~3400 on the application I tried.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
