that i dont really know how to describe... so i'm going to attach a screenshot...
i opened the lastest pharo dev image... checked to see if the redraw bug that i have been experiencing was still there...
went to quick and got a sudden flurry of message not understood errors ( see screenshot of the rearranged windows )... i wasnt able to reliably reproduce but, when doing the same thing ( open and quit... ) about 2 out of every five times i
got message not understood windows popping up.  _______________________________________________ Pharo-project mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project |

It would be helpful if you attach debug.log. This file is located in the same directory where the image is.

I didn't know that. logDebuggerStackToFile is the option?
It's strange because this is enable by default and I don't think Sean change it.

I think I founded the problem... I don't know what makes it happen or how to solve it yet :-)
But the problem is a raise condition. In method MouseOverHandler>>processMouseOver: anEvent the instance variable leftMorphs is set to nil, but when accessing that variable there
is no check for nil. So, if processMouseOver: anEvent is running in two different processes, in one leftMorphs could set to nil while in the other process is still been used... Is it possible for processMouseOver: anEvent to be evaluated in more than one process? If that is true, so that is the problem... if not, nothing makes sense...

I saw you are in Mac world which I know very little about. But, could this be a matter of permissions? what about a ls -la or something like that to see this ? Any other reason that can cause this ?
Several times I asked myself this. I don't know :(

permissions are fine. this gets even weirder, i left the image open and 10 minutes after the debugger was opened, the debug.log was created. here is the content from the file, given how long it took to be created, i'm not sure it has everything:

That's an old one... a bit late here so look it up
on Mantis. ANYTHING that manipulates morphs etc. in a process other than the UI
process is liable to break in one way or another.
The mouse over handler is just one of the most
frequent (most events)...
The workaround we have is to do the nil check. A
Workaround though...
Regards, Gary

Thanks.
I think that for the MouseOverHandler it would be good to know if this is related to Sensor changes. Mike what you think?

On the Morphic side there weren't any changes to process behavior, it still pulls the events out of the queue in the step cycle.

hmm, let me rectify what I said. Yesterday I had to errors related to this bug. The first one is the one that Sean says and I sent the fix in other mail. It check for leftMorphs to be nil in the method noticeMouseOver: event:
I look for sender of that message and are HandMorph and Morph, so that is not a raise condition but just something that can happen. But when fix that error I got another one in the method processMouseOver: , where it does "leftMorphs isEmpty " and there leftMorphs was nil and the only reason for that was a raise condition... but that error never happened againg....
Conclusion: I think just checking for nil in noticeMouseOver:event: is enough to solve the error, and I do not know why the other error happened but I may have been a really rare situation... Bye, Hernan. On Thu, Jun 4, 2009 at 4:11 AM, Michael Rueger <[hidden email]> wrote:

I used pharo for 3 months without seeing this error. I've only gotten this error in the latest images with the latest vm and get it constantly. Not occassionally, I can get this to happen at least
once every 120 seconds or so, sometimes more often. It would seem to be as an outsider, that something must have changed. _______________________________________________ Pharo-project mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project |

Would be good to investigate what might have changed in the call path that *sets* the variable to check why it is ending up being nil. Maybe it shouldn't be set or initialized to nil but to an empty collection in those cases?

I was going to suggest exactly that.
As a rule, I never use nil because if you do it you will have to check for it somewhere... nil is the root of most of the problems! if not, look at all the errors I fixed in the other mail, most of them are because nil is being used.
So, instead of nil, another object has to be use, and like you said in this case an empty collection I think will work. I'm just changing that... I'll send the changes today (I hope).
Hernan.

That's the Null Object Pattern!
