One PhD and two internships offers on object-centric debugging at Inria Lille
by Steven Costiou Nov. 9, 2021

Nov. 9, 2021

Hello, Inria Lille is recruiting one phd student and two interns to work on object-centric debugging within the OCRE project (ANR). DESCRIPTION OF THE PROJECT Debugging is difficult and costly. Object-centric debugging is a young technique arguing that focusing the scope of debugging on specific objects considerably eases the tracking and the understanding of hard bugs in Object-Oriented Programs (OOP). But it lacks fundamental bricks to be applicable in practice. Therefore, it has never been empirically evaluated. The objectives of the OCRE project are to study the fundamental and practical limits that hinder the implementation, the evaluation, and the adoption of object-centric debugging. We propose to build the first generation of object-centric debuggers, in order to identify and evaluate its real benefits to OOP debugging. We argue that these debuggers have the potential to drastically lower the cost (time and effort) of tracking and understanding hard bugs in OOP. PHD TOPIC The goal of this PhD is to understand and to achieve the full potential of object-centric debugging by: - identifying the precise scenarios for object-centric debugging, - studying means to obtain objects to debug, - studying the implementation requirements for object-centric debuggers and to implement prototypes, - evaluate empirically object-centric debugging using these prototypes. The full detailed offer is available here: https://jobs.inria.fr/public/classic/fr/offres/2021-04101 INTERNSHIPS These two internships aim at helping the design and the implementation of an object-centric debugger, by unveiling knowledge without which object-centric debuggers cannot be built and evaluated, or cannot be used in practice. Internship 1 - Identifying and acquiring objects to debug The objective of this internship is to study the practical problems of acquiring objects to debug. The intern will characterize the scenarios in which developers need to identify objects to debug and explore these scenarios by implementing prototypes. Internship 2 - Evaluating object-centric debugging scenarios The objective of this internship is to identify and to evaluate the debugging scenarios that are the most likely to benefit from object-centric debugging. The intern will interrogate real developers about object-centric debugging scenarios, then implement prototypes and evaluate them empirically with developers to validate these scenarios. ADMINISTRATIVE DETAILS Location: Lille, France Phd: - starting date: preferably october 2022, but it can start before. - duration: 3 years (fully funded) - the candidate must hold a Master or an equivalent degree Internships: - starting date: anytime - duration: 4-6 months - the candidate must be studying for a Master degree or equivalent (1st or 2nd year, equivalent to M1 or M2 in France)

a little help for my daughter :)
by Jannik Laval Nov. 1, 2021

Nov. 1, 2021

Dear pharoers, My daughter's school (2nd year of kindergarten, she is 4 years old) is organizing a project "Around the world". The goal is to discover the countries of the world by different means, one of which leads me to ask for your help :). The goal is to send a postcard from your country with the following text: "Bonjour l'Ã©cole des Petits Pas" (in English, "Hello School of Little Steps"), and in the language of your country. The card should be sent to : Ecole maternelle des Petits Pas, classe verte 42 rue GrassoliÃ¨re 38 790 Saint Georges d'EspÃ©ranche, France Thank you for your help, and I hope to see you at the next ESUG. See you soon, -- ~~Jannik Laval~~ Associate professor (HDR) - Information systems agility IUT LumiÃ¨re, UniversitÃ© LumiÃ¨re Lyon 2 DISP Lab - https://disp-lab.fr/ +33 4 78 77 43 06 http://www.jannik-laval.eu

We merged 34 PRs and closed 35 issues. Literal Sharing =============== Since Pharo9, literals are compiled as read-only objects. This used to be a source of ugly bugs (code accidentally changing a literal, but the source not showing it). As we now can not change literals, and identity changes anyway on recompile, we are free to unify literals over the whole image. This seems to save ~2MB with the current build. We do this once as part of the build, users with large code bases can re-run it (see ImageCleaner>>#shareLiterals) and save some space. - Enable-SharedLiterals #10186 https://github.com/pharo-project/pharo/pull/10186 - 10190-Literal-Sharing-unify-nested-arrays #10195 https://github.com/pharo-project/pharo/pull/10195 Speed ===== - Use-equivalentTo-ReEquivalentSuperclassMethodsRule #10183 https://github.com/pharo-project/pharo/pull/10183 Features ======== - 10200-add-isClassSide-to-CompiledMethod #10202 https://github.com/pharo-project/pharo/pull/10202 - 4211 easy support for equality and hash with nice default behavior #4803 https://github.com/pharo-project/pharo/pull/4803 - Migrating RBInlineMethodRefactoring into Refactoring2 #10163 https://github.com/pharo-project/pharo/pull/10163 - Parameter refactoring migrations #10162 https://github.com/pharo-project/pharo/pull/10162 Class Parser ============ Work continous on the class parser / fluid class definitions - Changing uses: and trait: to use traits: in the class definition. #10199 https://github.com/pharo-project/pharo/pull/10199 - Removing #<< from SequentialCollection class #10197 https://github.com/pharo-project/pharo/pull/10197 Fixes ===== - Autofixes on class side raise DNU #10235 https://github.com/pharo-project/pharo/pull/10235 - fix: #10211 addSearch: -> addRule: adding two little tests to start #10220 https://github.com/pharo-project/pharo/pull/10220 - 9973-Different-behavior-in-Playground-for-deprecated-method-transformed-vs-nontransformed-deprecations #10222 https://github.com/pharo-project/pharo/pull/10222 - [P10] 8170-Pharo-image-freeze-on-Windows-after-some-hours-Idle-P10 #10188 https://github.com/pharo-project/pharo/pull/10188 - 10193-testNoEquivalentSuperclassMethods-failing-on-ci #10194 https://github.com/pharo-project/pharo/pull/10194 Cleanup - Old Blocks / Bytecode =============================== Cleaning the core system and compiler - 9929-Reflectivity-compiler-still-uses-pushClosureCopyCopiedValuesargsjumpTo #10177 https://github.com/pharo-project/pharo/pull/10177 - Cleanup-FullBlocks: remove dead code #10221 https://github.com/pharo-project/pharo/pull/10221 - Cleanup-optionFullBlockClosure #10229 https://github.com/pharo-project/pharo/pull/10229 - Remove-EncoderForV3PlusClosures #10181 https://github.com/pharo-project/pharo/pull/10181 - Fix 10178: Cleanup OldBlocks Compiler/Decompiler #10180 https://github.com/pharo-project/pharo/pull/10180 Cleanup ======= - Cleanup-Deprecated9-More #10236 https://github.com/pharo-project/pharo/pull/10236 - Release test to ensure we have no protocol names with leading or trailing spaces #10233 https://github.com/pharo-project/pharo/pull/10233 - Mark a few abstract refactorings #10246 https://github.com/pharo-project/pharo/pull/10246 - Mark abstract classes in Ring #10250 https://github.com/pharo-project/pharo/pull/10250 - "Tools-Test" package should be "Tools-Tests" #10244 https://github.com/pharo-project/pharo/pull/10244 - Fix lint in Array>>#copyWithDependent: #10252 https://github.com/pharo-project/pharo/pull/10252 - Cleanup: no leading or trailing space in method category name #10230 https://github.com/pharo-project/pharo/pull/10230 - 10205-LiteralVariable-classcheckValidName-has-commented-out-code #10207 https://github.com/pharo-project/pharo/pull/10207 - Remove empty protocols in ZnStaticFileServerDelegate #10224 https://github.com/pharo-project/pharo/pull/10224 - Cleanup-hasLinks #10206 https://github.com/pharo-project/pharo/pull/10206 - 10191-MCClassDefinitionring2LayoutType-misses-Double-layouts #10192 https://github.com/pharo-project/pharo/pull/10192 - Fix a few lints regarding categorization of "converting" #10175 https://github.com/pharo-project/pharo/pull/10175 - Adopte testNoUncategorizedMethods #10169 https://github.com/pharo-project/pharo/pull/10169 Pharo9 ====== [P9] 8170-Pharo-image-freeze-on-Windows-after-some-hours-Idle #10179 https://github.com/pharo-project/pharo/pull/10179
