[Pharo-project] mixing open and closed source within Pharo
by Ben Coman June 4, 2012

June 4, 2012

What ideas are floating around about mixing open source and closed source using Pharo? I am implementing an IEC Standard object model for electrical power systems to provide a platform for developing electrical applications. I am considering the case where a company may maintain the model of their electrical power distribution network in the open source platform, but then buy various commercial plug-ins perform different calculations upon the shared model. Here are the options I can imagine... 1. Using fuel to load binary packages within the one image without the source. Currently available technology but viewing and decompiling bytecode is still possible - but to what degree this enables reverse engineering I am not sure. 2. Having VM support for restricting displaying/decompiling bytecode. To avoid the ease of switching to another VM without this restriction, the fuel package could be encrypted with a key match one compiled inside the required VM. 3. Running multiple images on a single VM such that the VM passing message calls efficiently between the two images like an "enterprise bus*" - one open source and one closed source. Any common base objects between the images might be shared on a copy-on-write basis. What are your thoughts? cheers -ben

[Pharo-project] McHttpRepository and text/plain
by Stuart Herring June 4, 2012

June 4, 2012

Hi all, I recently ran into the problem with a server returning text/plain instead of application/octet stream again (see http://lists.gforge.inria.fr/pipermail/pharo-project/2012-April/062388.html) but the resulting error (a MNU for Character>>bitOr:) failed to job my memory as to the actual cause. Is there any chance the final line of McHttpRepository>>readStreamForFileNamed:do: could be changed from: ^ aBlock value: contents readStream to: ^ aBlock value: contents asByteArray readStream I know that it would be best if Web Servers never served up binary content as text/plain - but it's not always in the power of someone who encounters this error to fix that. Failing that, the condition should probably be explicitly checked for and a more useful error message given, as the cause is far enough away from the symptom that it takes a bit of digging to find out what went wrong. Regards, Stuart

[Pharo-project] Some steps towards headless on OS X
by Mark Smith June 3, 2012

June 3, 2012

Hi all, The underlying problem with headless mode in OS X seem to be that we always create a window, even when we run in the background, as we do in headless mode*. Marking the process as background only will remove the icon, menu etc. but it will not stop us from creating that window. Maybe I don't know enough about how Squeak/Pharo works right now but it looks like quite a lot of work to change this. And the code isn't pretty ;). Anyway I'd like to keep working on this but I've hit a wall. I can handle the Cocoa side but don't know anything about the VM's setup process etc. Could someone clarify this? Or maybe there are some docs? Also â What do you guys think about building a headless VM without any of the UI stuff in it? It might be simpler/cleaner than what we have now. All the best, Mark * Creating the window is almost the first thing we do! We do it before we know if we're running headlessâ¦

Hi guys In 20, which T1>>m1 is defined under cat1 when we do T3 uses: T1 T3>>m1 is 'as yet unclassified' and this breaks several tests. Any idea of a change that could have modified the system? Stef
