[Pharo-project] Which packages are loaded in the image?
by Sean P. DeNigris April 18, 2012

April 18, 2012

It took a bit of time to figure it out... I finally came up with: MCPackage allInstances asSet collect: [ :e | e name ]. I started with three seemingly equivalent operations which all returned different results in 1.3 (not in 1.4): packageNames := MCPackage allInstances collect: [ :e | e name ] as: Set. all := MCPackage allInstances. set := MCPackage allInstances asSet. packageNames size. "235" all size. "236." set size. "234." It turned out to be the 'bogus' and 'bogusext' packages that were throwing the results off (the first is duplicated in the image and the second is duplicated with case differences). Given the names, I'm guessing it's not too important, but still confusing. What's the best way to do the above? How do we prevent future queriers from this confusion? Thanks.

[Pharo-project] [JOB] Young Engineer: Smalltalk VM related
by Marcus Denker April 18, 2012

April 18, 2012

2 year Young Engineer Position =============================== INRIA RMoD is looking for a full-time young engineer for helping with developing our research infrastructure. Young engineer means someone who finished with a degree (Master or Engineer) not longer than 2 years ago. The engineer position is focussed on virtual machine related work. As researchers, we need a system to explore new ideas with. The job of the engineer is to help us by improving the infrastructure we use for our daily work. What this of course means is that it's kind of a cool job: work in a research lab, but no paper writing, no teaching, no administration. In addition: - live in France (one hour from Paris, 1h20 from London, 35 min from Brussels) - try a lot of good beers (our office is just 10km from the border to Belgium) - french food - Smalltalk! (in the form of Pharo) Lille is an active city but not expensive (lot of students...), centrally located with good connections by train to everywhere (including CDG and Brussels airports). The idea of the job is to strengthen RMoD with regard to virtual machine development and improve our research infrastructure. In research we are often faced with doing experiments that need VM changes. We want to be able to make these changes as easy as possible so researchers can focus on trying out new ideas. In particular we are working on an easy to understand and modify research virtual machine that is implemented in Smalltalk. The goal here is not a fast production VM but instead infrastructure that is easy to learn and extend for research experiments. The job will include working on the research VM as well as helping with Pharo related VM level development: - extend and develop the research VM. - implement a simple GC in Smalltalk for this VM. - help with Pharo VM related development (build system, fixes, improvements) - improvement of the NativeBoost native code backend. Therefore we are looking for a candidate with some prior experience with Smalltalk (Pharo/Squeak) and possibly some background in implementation of dynamic languages. - Knowledge in Dynamic Languages, preferably Smalltalk - Compiler construction - Implementation of dynamic langauges (Virtual Machines) - Good knowledge in low-level programming (C, Asm) - English Duration: 24 months Starting date: 2012 October or later Sallary: 2 527,74 euros brut / month Location: Lille (no remote job possible) Needed: - degree (Master or Engineering, 5 years) - need to have finished the degree max 2 years ago.

[Pharo-project] Help with RPackage and FuelPackageLoader
by Mariano Martinez Peck April 18, 2012

April 18, 2012

Hi guys. I have spent several hours trying to find a problem with Fuel and RPackage and I couldn't. We have a test where we create a package, we create a class and we compiled some methods. Then we serialize the package, we remove it, and then we materialize it. In a clean Pharo 1.4 image this works PERFECT. No problem. Now, if I run it in the Nautilus image (where RPackage is loaded) I have lots of problems. I am completly lost of what is happening. But it is reproducible. So I really appreaciate any help. To reproduce: 1) Take a Nautilus image from: https://ci.lille.inria.fr/pharo/view/Nautilus/job/Nautilus-Release/ 2) Install Fuel: Gofer it url: 'http://ss3.gemstone.com/ss/Fuel'; package: 'ConfigurationOfFuel'; load. (ConfigurationOfFuel project version: #bleedingEdge) load: 'DevelopmentGroup'. 3) Open a TestRunner and just run the test class FLPackageLoaderTest. Once that finish, you will have like 20 debuggers opened. In addition, like 4 error test. Without Nautilus I have only ONE red test and no debuggers. The debuggers are all in the line: self flag: 'should not arrive there now'. self halt. from CompiledMethod >> packageFromOrganizer: Thanks for any help, -- Mariano http://marianopeck.wordpress.com

[Pharo-project] SmallLint and manifest
by Simon Allier April 18, 2012

April 18, 2012

Hi pharoers Since a couple of months the Pharo team has been working on improving the support for rules checking and in particular the handling of false positives (there is nothing more boring that to get all the time the same warnings that we know are not adequate). We added a manifest mechanism to manage the false/true positive of SmallLint, the rule checker of Pharo. A manifest is a class that contains meta data. In the future we may add package license and package documentation. This data is stored in methods on the meta side of the class. So, manifest can be versioned in Monticello and not lost. There is one manifest per package. It possible to use SmallLint with Manifest using the Critics Browser (menuWorld > Tool > CriticBrowser). With the Critics browser you can inspect violations of rules and mark them as false positive or true positive (ToDo) and see previous warnings flagged as false positives or toDo. In addition all the logic of the browser has been developed so that the manifest can be saved within the package without adding dependencies. We will continue to improve the Browser. In addition we will run SmallLint rules to all the Pharo packages and the rules checking will be part of the package validation. We want the community to use rule checking for real so that we all improve. Simon and Stef Gofer new url: 'http://www.squeaksource.com/PharoTaskForces'; package: 'ConfigurationOfManifest'; load. ((Smalltalk at: #ConfigurationOfManifest) project version: #stable) load
