[Pharo-project] Troubles with #flushCache and #run:with:in:
by Lukas Renggli July 11, 2011

July 11, 2011

Hi Eliot, I am using one of the latest VMs from your site (VM.r2434) and I continue to have subtle problems with objects as methods (#flushCache, #run:with:in:). The issue is that the test coverage in Pharo is kind of broken on Cog for a long time already. It reports methods as not covered that are clearly covered, and tests seem to randomly fail. I suspected that there is something wrong with the coverage code itself. So I started to experiment with TestCoverage>>flushCache and noticed that the current implementation TestCoverage>>flushCache self reference methodSymbol flushCache performs not that well: The set of not covered methods is wrong and many tests suddenly fail. If I replace it with TestCoverage>>flushCache self reference actualClass flushCache I actually get accurate coverage information, but there are still a few tests constantly failing. I tried to use all possible combinations of #flushCache (also calling it on the compiled method), but only flushing the cache on the class seems to work properly. So far so good, but I really wonder what the correct way is to flush the cache? :-) For my experiments I was using the package 'AST-Tests-Semantics'. This is a small package with lots of test methods that cover each method but one (RBSemanticAnnotationMisssing>>#isResumable). Now the "real" problem is that when running these tests in coverage mode, the same 4 tests always fail: RBSemanticTest>>testBlockScope RBSemanticTest>>testCascadeReceiver RBSemanticTest>>testClassVariableBinding RBSemanticTest>>testGlobalVariableBinding Not sure of how to debug that? Do you have an idea why these otherwise passing tests suddenly fail? If you want to try to reproduce you can use any Pharo image with the tests loaded, or use those that I used: http://jenkins.lukas-renggli.ch/job/Development/lastSuccessfulBuild/artifac… http://jenkins.lukas-renggli.ch/job/Development/lastSuccessfulBuild/artifac… Open the Test Runner, select 'AST-Tests-Semantics' and 'Run Coverage'. Any help or clarification would be appreciated :-) Lukas -- Lukas Renggli www.lukas-renggli.ch

[Pharo-project] loading OSProcess in Pharo1.3
by Johan Brichau July 10, 2011

July 10, 2011

Hi guys, I'm (finally) trying out the new Pharo1.3 Yesterday I had a couple of issues with build 13284 but 13285 seems to fix these. Great! But I'm now trying to load OSProcess in Pharo 1.3 and OSProcess tries to add its image startup script to the list right after ImageSegment's image startup script. However, it appears that #ImageSegment is no longer in the startup list, which yields an error. I don't know if this is expected, so I thought I should email it here. For now, I changed OSProcess so that it adds its startup script right after SmalltalkImage instead. I'm not sure if that is OK though... it's just a quick fix I made right now. I'm not sure what the prerequisites of OSProcess are in that respect. Any thoughts? Johan

[Pharo-project] Installing Cog - was Pharo 1.2.1 crashing
by Schwab,Wilhelm K July 9, 2011

July 9, 2011

Sig, Is there anything I should know about using the Stack or Cog vms from Hudson? It looks like the zips contain a vm, some external plugins and drivers. Can they simply be dumped in a directory with the image/changes and launched using a shell script? Below, are you recommending the Stack vm to remove Cog features that might be causing problems?

Hi guys I was discussing with Sven and I think that we could improve two things: - better marketing: T3 Easy is the example of Pharo on the server! We should add this to our success story web page T3 Easy is our new entry level track & trace product, an HTML5 web app (using client side HTML+Javascript+CSS) on top of a REST server written in Pharo Smalltalk. It consists of 4 stateless Pharo Cog VM's running behind an Apache load balancer. The server uses Zinc HTTP Components, both for its server part, as well as for clients talking to other systems behind the scenes. Even the Open Street Map tile serving, which is pushing out many megabytes, is currently going through this server. Here is a live demo URL in case your are curious: http://easy.t3-platform.net?t=livedemo - More exchanges between companies building on top of pharo. Sven showed us its automatic deployement infrastructure (using monit) and the automatic update and it was really what you want. Four server automatically restarting and ... So I would like to urge you companies guys to create a pool of knowledge and recipe around pharo. If you have docs/scripts I can put them in shape for a deployment chapter Stef
