How to Stop/Cancel a Process

[floboc]

I am using the Process framework, with some automatic function calling.
I would like to interrupt / stop / cancel the running Process from an external source (like a user pressing a "Cancel" button).
For instance, I have some process steps using automatic function calling, and sometimes they get stuck in a kind of a loop, which I would like to cancel.

However, I cannot find a way to achieve that.

I am using the StartAsync method to start the process (as in the documentation).
This is the source code of that method for reference:

public static async Task<LocalKernelProcessContext> StartAsync(this KernelProcess process, Kernel kernel, KernelProcessEvent initialEvent, IExternalKernelProcessMessageChannel? externalMessageChannel = null)
{
    Verify.NotNull(initialEvent, nameof(initialEvent));

    LocalKernelProcessContext processContext = new(process, kernel, null, externalMessageChannel);
    await processContext.StartWithEventAsync(initialEvent).ConfigureAwait(false);
    return processContext;
}

It seems like LocalKernelProcessContext does have a StopAsync(...) method that oculd be used for my purpose, but the issue here is that await processContext.StartWithEventAsync(...) actually waits for the entire process to finish.

Indeed, the StartWithEventAsync method internally calls this._localProcess.RunOnceAsync(...) which waits for the entire process to finish.

Also I couldn't find any way to provide a cancellation token either.

Hi @floboc, currently we don't have this functionality but it is on the roadmap.
As a temporary solution perhaps, a loop may signal the need of a "check step" that if exceeded certain count/time it can end the process with something like:

myStep
    .OnFunctionResult()
    .StopProcess();

myStep
    .OnEvent("myThresholdEvent")
    .StopProcess();
