Re: [Pharo-dev] Building Pharo using Interpreter Class

by Kirstin Heidler

But the StackInterpreter and Stack VM should be working, right? We just found out, that once an Image has been saved with a Cog-VM there can be issues with floating points because of the ordering of bits? LE vs. BE? At least it says so in this README [2]. May this be one of the problems we had when trying to start our image with the generated StackVM? Also, which Pharo version do you reccomend to use? We downloaded the one from this [1] repository. I think it is a Pharo 2.0? Thanks a lot for your help. Nice to know that the Interpreter class is not working. :) Kirstin [1] https://github.com/pharo-project/pharo-vm [2] http://www.squeakvm.org/svn/squeak/branches/Cog/README Am 03.12.2013 14:10, schrieb phil(a)highoctane.be: > Oops.

Because then, files can also open/close and delete themselves automatically, so you will be left only to do reading and writing... Resource management is an application-level responsibility, not framework level. I cannot predict in Athens, how often one wants to create/destroy or (re)use surfaces, and therefore i cannot create and dispose them when i see fit within framework.

Re: [Pharo-dev] Roassal Bug related to Athens?

by Usman Bhatti

Igor, I had a look at Athens demo to understand how to manage sessions and surfaces because Roassal uses AthensSurface and there is a defensive mechanism in place in Roassal to initialize the surface in case it is not done. In the meantime, I have discovered that the red rectangle bug is present in Athens demos as well. So, to reproduce. AthensFlakeDemo new openInWorld save image open image I tested in Moose 5.0. 1. Should I open a bug entry in Pharo? 2. With my superficial knowledge of Athens, my guess is that the session management can be done in Athens so that Roassal (and other tools built on top of Athens) do not need to do it. May be it is the case already but the demos are not using it then.
