</div>
<div>Hi all,<br>
<br>
please see the attached changeset which implements "debugging through fork" based on SimulationSideEffect. Please load SimulationSideEffectWarning.5.cs before loading the attached changeset.<br>
<br>
Hope you like it! Still, I did not withdraw my caveats from my previous message, so maybe we should test this change for some more time. I would recommend merging this patch after the release (but SimulationSideEffect) before the release. Looking forward to
your opinions. :-)<br>
<br>
Best,<br>
Christoph<br>

<b>=============== Summary ===============</b><br>
<br>
Change Set: debugFork<br>
Date: 6 February 2022<br>
Author: Christoph Thiede<br>
<br>
This changeset allows to debug forked/resumed processes. When users steps through/into a send that will resume another process, they are presented a small dialog to either resume the process or debug it.<br>
<br>
See: http://lists.squeakfoundation.org/pipermail/squeak-dev/2022-January/218552.html<br>

maybe as an opt-in or when combined with some clever heuristics.<br>

this one soon. :-)<br>
