Reinitialize processes?

Is there a simple way to kill all the forked Smalltalk processes and restart the UI process?

Thanks,

-Carl

Re: Reinitialize processes?

Hi Carl,

when you open a debugger, you have a menue entry "Processes", choose "Debug Other" and select the ones you want to kill.
They should then be displayed in the top list of the debugger and with a right click on one or several you will be able to terminate them.

Re: Reinitialize processes?

Thanks Sebastian. I know about that. I wasn't clear in my question. I'm wondering if there is a way to do this from a workspace by evaluating an expression.

Here is one example. It doesn't do what you want, but it should set you on the path. There are two parts to it. 1) Determine which processes you want to play with. 2) Do something to each such process. Use #terminate to kill a process, but be aware of unintended consequences. Killing a process that is busy doing something may break things. In general, I would say the probability is low, but it is non-zero.

| broken |
broken := (Processor availableProcessesExcept: #())
    select: [:each | each isSuspended and: [each processName beginsWith: 'Idle ']].
broken do: [:process | 
    | frame |
    frame := process framesDetect: [:each | each method selector == #finalizedSlot:removedObject:] ifNone: ['no such frame'].
    frame ~= 'no such frame' ifTrue: [
        frame dropToFrame.
        process resume.
    ].
].

Re: Reinitialize processes?

Thanks Richard for the interesting example.

I realize that mechanisms for managing processes must be well designed and robust. My need is simply to have something helpful for use when developing to knock processes over the head when things go wrong and I don't want to take the time to reload the image and start again from zero.

Thanks again,

-Carl
