Running tests for auto-built Cog VMs
by Igor Stasenko 18 Mar '11

18 Mar '11

Hello all. Our next plan is to extend the Hudson build jobs with tests which are run after VM has built. I'd like to ask, what kind of tests we should run for VMs. So, here's my questions: - do we need a VM specific tests? Or we just use ordinal tests which are in image(s) by default? - in case if we need to run VM-specific tests, is they are available somewhere or not? do we need to create separate package/repository for holding them? i'd like to brainstorm that a bit. And then we will do that. -- Best regards, Igor Stasenko AKA sig.

VM Automated builds update
by Igor Stasenko 18 Mar '11

18 Mar '11

A) We split the build on two stages: 1. job which watching the git repository , and then checks out latest version of sources and builds image with VMMaker preloaded in it. An output of this job is: - archived snapshot of checked out sources - archived image with VMMaker + CMakeVMMaker installed 2. job which takes the results of above one, and generating sources files and cmake configuration (specific to target build) and then makes VM An output of this job is: - achive containing - checked out sources + generated source + cmake configs + image with vmmaker - a built VM B) We finally were able to run build process on Mac slaves and as result, build Mac-specific VMs. See following for a list of jobs: https://pharo-ic.lille.inria.fr/hudson/view/Cog/ Here jobs which are working now and you can download produced artifacts from them: Cog Linux JIT: https://pharo-ic.lille.inria.fr/hudson/view/Cog/job/Cog%20Unix/ Stack VM Linux: https://pharo-ic.lille.inria.fr/hudson/view/Cog/job/Stack%20VM%20Unix/ Mac Cog Jit (Carbon) https://pharo-ic.lille.inria.fr/hudson/view/Cog/job/Cog%20Mac%20Carbon/ Mac Stack VM (Carbon) https://pharo-ic.lille.inria.fr/hudson/view/Cog/job/StackVM%20Mac%20Carbon/ Once Esteban adopt his sources to our build system, we will also build a Cocoa versions of Cog/Stack VMs for Mac. (btw, prod Esteban to produce config for cross-compiling Stack VM for iPhone target :) -- Best regards, Igor Stasenko AKA sig.

[OFF-TOPIC] Word from Kyoto (was Re: [Vm-dev] SVN email commit notifications)
by Casey Ransberger 18 Mar '11

18 Mar '11

Folks, forgive me for being an email philanthropist. Ian, who is alive and well, recommends this link to folks who want to help with the situation. He probably wouldn't spam the list with it, but I suppose such a social transgression is what I'm here to do. He pointed me at the below link, which reduces the barrier to contribution about as far as it'll go, recommends the Japanese Red Cross, and stresses that you *don't* want your local chapter, but the Japanese Red Cross: http://www.google.com/crisisresponse/japanquake2011.html Since a few people on the list have expressed a desire to help out, I figured I'd step right over the off-topic issue and just click send on my way to get the contingency card out of the safe.

PrimErr* missing (standard VM)
by Javier Pimás 18 Mar '11

18 Mar '11

I'm not sure why/when this started happening, we just tried to update to latests versions of Alien and standard (old) VM by loading monticello versions (manually). When using PrimErr* in SqueakNOS plugin methods, they are written in red, as if they are globals that were not defined. On the other side, we are seeing that they are defined as class vars in Interpreter, so it makes sense that they are not found as globals, maybe they were moved in some update? Finally, Interpreter>>initializePrimitiveErrorCodes looks at special obj array at: 52, which is nil, so how can I initialize it? And also, how should we send primitiveFailFor: message? Thanks! Javier. -- Javier Pimás Ciudad de Buenos Aires
