Hi folks. This is why I like writing in books/wikis, because I always learn :) Now I writing in the book about the Interrupt Key and I come up with this guy I was not even aware of: CPUWatcher. It seemss very cool and useful. However, I am using it wrong, or there is too much dust on it. I want to ask if I am using it well before debugging and try to make it work. As the class comment says, I tried to do this: CPUWatcher startMonitoring. "process period 20 seconds, sample rate 100 msec" And then I evaluated in a workspace: [ true ] whileTrue: [ 1+1 ] It should stop that process when it is using 80% of the CPU, but it doesn't. The process is never stop and the image freeze. I then tried: CPUWatcher startMonitoring. "process period 20 seconds, sample rate 100 msec" CPUWatcher current threshold: 0.3. "change from 80% to 30%" I have the same results... any hints? Cheers Mariano

Your code doesn't have any message sends when executed, so it can't be interrupted. Btw, you can turn CPUWatcher on from the Process Browser and see the CPU usage of processes. Levente

Hi Levente. Thanks for the answer, but I didn't understand. Which code do you mean? If you refer to: [ true ] whileTrue: [ 1+1 ] I am sending the message whileTrue: to BlockClosure and the message + to 1. So, I don't understand. Btw, you can turn CPUWatcher on from the Process Browser and see the CPU
usage of processes.
Yes, I tried this before but it happened the same....I tried to test it, evaluating [ true ] whileTrue: [ 1+1 ] but it was not interrupted. I also tried to click several times in the world but with no luck. Thanks Mariano
Levente
Cheers

In theory yes, but in practice no. Just look at the generated bytecode: 13 <71> pushConstant: true 14 <9D> jumpFalse: 21 15 <76> pushConstant: 1 16 <76> pushConstant: 1 17 <B0> send: + 18 <87> pop 19 <A3 F8> jumpTo: 13 21 <78> returnSelf As you can see #whileTrue: totally disappeared, no message sends. There's a send for #+, but that's a B0 bytecode which will not do a real message send, because both the receiver and the argument is a SmallInteger. Therefore your code won't send any messages.

ahhhhh ;)
13 <71> pushConstant: true 14 <9D> jumpFalse: 21 15 <76> pushConstant: 1 16 <76> pushConstant: 1 17 <B0> send: + 18 <87> pop 19 <A3 F8> jumpTo: 13 21 <78> returnSelf

Ok...I got it. But now I tested with this: [true] whileTrue: [ Transcript open. Transcript show: 'mariano'. Transcript close. ] With bytecodes: 33 <71> pushConstant: true 34 <AC 0C> jumpFalse: 48 36 <41> pushLit: Transcript 37 <D0> send: open 38 <87> pop 39 <41> pushLit: Transcript 40 <23> pushConstant: 'mariano' 41 <E2> send: show: 42 <87> pop 43 <41> pushLit: Transcript 44 <D4> send: close 45 <87> pop 46 <A3 F1> jumpTo: 33 48 <78> returnSelf Now it should work, isn't it ? However, I still it doesn't interrupt the process :( Thanks for the help levente. Mariano
