I would argue that it be a better idea to make the process browser more robust with regard to invalidations of this kind. At least, the process browser is scanning all Process instances in the image. When I create some stub objects/degenerated processes through SimulationStudio, I'm also confused that the process browsers fails to display anything afterward.


Anyway, thank you for fixing this, Jaromir! :-)


Best,

Christoph

Betreff: [squeak-dev] The Trunk: Kernel-jar.1473.mcz

Marcel Taeumel uploaded a new version of Kernel to project The Trunk:
http://source.squeak.org/trunk/Kernel-jar.1473.mcz

==================== Summary ====================

Name: Kernel-jar.1473
Author: jar
Time: 31 May 2022, 11:31:14.576719 pm
UUID: 53473e84-779a-8a4c-9bf5-32a53197cd05
Ancestors: Kernel-mt.1472

Fix a bug causing an endless stream of error windows poping up when debugging e.g.
        [] newProcess
when Process Browser is open with auto-update on.

Once the suspendedContext is set, the new process is no longer considered terminated and Process Browser will try to place it in its list of processes but encounters a nil error when reading its priority because it has not been set yet.

=============== Diff against Kernel-mt.1472 ===============

Item was changed:
  ----- Method: Process class>>forContext:priority: (in category 'instance creation') -----
  forContext: aContext priority: anInteger
+        "Answer an instance of me that has suspended aContext at priority anInteger.
+        It's important to set the priority before setting the suspendedContext; otherwise
+        an endless stream of error windows will start poping up when debugging e.g.
+                [] newProcess
+        when Process Browser is open with auto-update on."
-        "Answer an instance of me that has suspended aContext at priority
-        anInteger."

         | newProcess |
         newProcess := self new.
-        newProcess suspendedContext: aContext asContext.
         newProcess priority: anInteger.
+        newProcess suspendedContext: aContext asContext.
         ^newProcess!
