Process browser: next generation

Hello!

We are currently working on a new process browser (codename: Loom). You have probably noticed that the Process Browser is not exactly the tool you want to use to understand how processes behave. The process browser may be one of the oldest piece of Pharo code that has not been touched for a long long time.

We are going toward something that looks like the Activity Monitor (e.g., [*]), useful to find out which programs is heating up your laptop. We will have nice curves that shows you the CPU consumption. Something that the process browser has never been able to do.

What are the features you would like to see in it?

Cheers,
Alexandre

An ability to jump to the process code right away.

Have a working CPUWatcher

Did it work on some point? I read the documentation but could not find out how to give a meaning to it. Looks like a half-finished thing.

Isn't that the case in the current process browser ?

Or do you mean something like forcing a breakpoint in a currently
running process ?

( It would be cool to breakpoint like that the main UI process... :)).

Main UI process and a haltOnce would indeed be great instead of the current kata.

Well, it would make up, in some cases, for the fact the "emergency"
interrupt key doesn't work (in 1.3, 1.4 and 2.0 all versions under Linux).

Except that you wouldn't be able to open the browser, no? IIRC Igor had some ideas about more robust interrupt behavior... ah, yes, here it is...

I'd be a lot safer if I could "trace" the main UI process instead of
blocking it.

Maybe block it, kill it (keep the stack) and restart a new one
immediately (in a safe UI context with say just the debugger open) so
that I can explore the current state and eventually let it proceed.

-- Remote debug from another Pharo image ?

Did it work on some point?

Yes.

I read the documentation but could not find out how to give a meaning to it.

The idea is that you can enable a process who's goal is to watch the CPU usage and if it goes over, say 80%, then it halts and tries to stop that process. It is useful when there is an infinitive loop or something like that.

Looks like a half-finished thing.

Alexandre
