Re: [Pharo-project] Event history question

by John M McIntosh

Actually it's Michael who is messing in this area to improve the event handler for Pharo (and in general) as part of some funding from ESUG for the iPhone VM development work. Me? I'm just an innocent bystander. I'd assume he has to fork off any logic with low io process priority which is what I think happens if you follow the bouncing ball by reviewing what installInterruptWatcher and handleUserInterrupt do. The key consideration is that fetchMoreEvents is the trigger, not the code in the VM.

[Pharo-project] tx...

by StÃ©phane Ducasse

Hi guys I just wanted to tell you that I really like what we are doing. I was so sad in the past. I find really important that our (marcus and me) little flame inside did not die after 3.9. I would really pharo to be able to move forward even Smalltalk (first class slots for example)! I still have the idea that the system should be beautiful and that one person can understand it. Stef

Apparently my tests were wrong. Now I do not understand since when I run the tests the icons do not change.

Also, i think, it would be good to guarantee that there is only single Process which making calls to primitive and fetching events from VM - obviously the event ticker process. The rest processes should be allowed to talk with Sensor only through shared queue. -- Best regards, Igor Stasenko AKA sig.
