Re: [Pharo-project] InputEventFetcher starving all other processes
Yes mike rueger changes the poll behavior of the sensor. The idea is to get rid of polling. Stef On Oct 31, 2010, at 5:06 PM, Stefan Marr wrote:
Hi:
I am currently trying to get Pharo running smoothly on our RoarVM. However, there seem to be some changes in Pharo which lead to the image not making any progress.
For my experiments, I am using the latest 1.2 core image.
Do you know about any changes in Pharo, compared to Squeak 4.1, with respect to input event retrieval and perhaps the event processing?
Thanks Stefan

But the symptoms are that InputEventFetcher>>primGetNextEvent: delivers 500-1000x more events than EventSensor>>primGetNextEvent: in MVC or Squeak 4.1 images deliver. Could there be something else in PharoCore which interacts with the VM in unexpected ways? In case that is relevant, the RoarVM uses X11 for the interface.

Turns out that the array which is supposed to be filled in by '>>primGetNextEvent: array' does not get filled in correctly. For some reason the old values stay in the array when there isn't any new event.
However, the very same code works for the non-Pharo images. Was there any change to the code in or related to this primitive (<primitive: 94>) lately?
