Pharo image freeze and "Alt-." has no effect

Steven Rémot
Hello everyone,

I'm new to pharo, and was writing a simple 2D game with Athens for rendering to practice a bit. I'm loving the environment so far, developing the game while it's running is really enjoyable :-) .

However, when the game is running, the pharo image will freeze at a random time. Alt-. doesn't make my image back to normal, the only solution I found is closing my image and opening it again, until the next freeze...

I don't really know what to do to investigate this bug, there is no output from pharo about this. The only thing I thought about is starting from a fresh image, importing my code and running it again to ensure it wasn't some messy state in the image I was using, and it froze even when running my code from a fresh image.

What can I do to debug it? Do you need more information to give me a direction?

Just in case you need it, here is the source: https://www.dropbox.com/s/pfn7ccw27i4nqr7/Creakout-debug.st?dl=0

Thanks,
Steven Rémot

Hi Steven,

Can you tell us which platform you're on, and the output of pharo --version

Cheers, 
Alistair

Re: Pharo image freeze and "Alt-." has no effect

Steven Rémot
I think I got rid of the freeze by removing my implementation of layoutChanged in my morph:

  CreakoutMorph>>layoutChanged
      super layoutChanged.
      surface := AthensCairoSurface extent: self extent.

I used it to always have a surface that fits my morph whenever it's resized.

I can totally live without it, but I'm really curious to know what makes this code freeze my image sometimes, if ever someone knows it!

It looks like the freeze is not present on the latest dev release Ben. I will tell you if it just takes time to appear but it looks much more stable.

Thanks!

welcome. I hope that you will make a great implementation. 
If you have a reproducible case where alt+ does not work we are interested. 
Denis improved the situation but we lack of a case that we can reproduce to 
improve it again.

Steven Rémot
Thanks Stephane ! I still get the freeze sometimes, but it's still really random, I can't find a way to reproduce it for sure. I had much less freezes on Pharo 5 the moment I stopped dumping and recreating athens surfaces at each layoutUpdate, that's all... I tell you if I find how to make it freeze for sure on Pharo 5 and on the dev snapshot.
