Other than that, I think they happen "seemingly" at random. There are many sorts of internal dependencies, so other than the old workaround of making multiple .mcz's without internal dependencies, one kind of needs an insight into what exactly was at fault here to see if anything could be improved of the loading order in the general case, which does not simultaneously break something else...

I debugged the problem a bit. Stepping through the whole loading step. #loadDefinitions is already executed during opening and showing the package in the browser. It needs it, I think, for instance to show the commit message. And that is not the problem. Stepping through MCFileRepositoryInspector>>#load reveals that the image freezes on installing the method additions. (methodAdditions do: [:each | each installMethod].) There are for instance changes in Behavior and TPureBehavior. In general there is a dependency between changes, and a wrong order can easily break things. So, I checked whether the order in methodAdditions actually reflects what is in the change set. And the order is not consistent. So, what ever the approach is to decide on the order in the source.st, it is more stable/reliable in this case than what is in the binary snapshot. Any ideas to make these things consistent?

Would that mean it might be an idea to instead use Notifications here, and let the caller handle them if necessary/appropriate? Cheers, Henry

[Pharo-project] How to resurrect an unrepsonsive image?

by Norbert Hartl

I have a headless image that was running for a couple of days. Now it is not responding anymore. The image was running still but the sockets for http and vnc were closed and restarting the image just brings it up without any sockets opened. Injecting something via script does not work either. I copied the image to my desktop and tried a few things but no success. What would be a good way to get a glimpse of what is causing problems? I had Scheduler running that saved the image every hour. And the image itself issues http request to the outside world every 10 minutes. thanks, Norbert
