Who I am! !2 Pablo Tesone Pharo Consortium Engineer • 20 years trying to code • 10 years of experience in industrial applications • PhD in Dynamic Software Update • Interested in improving development tools and the daily development process. • Enthusiast of the object oriented programming and their tools.
- 3. Pharo 7.0 https://pharo.org/news/pharo7.0- released 2142 issues! Latest update 7.0.4 : August’19 !3
- 4. Pharo 7 in a Nutshell • 64-bit version in Linux, OSX and Windows (preview) • PharoLauncher • Totally new build process with full bootstrap from sources • All source on http://github.com/pharo-project/pharo • Iceberg: git client significantly improved • Calypso, the angular stone of PharoThings, new system Pharo browser !4
- 5. Pharo 7 main points… • Stateful traits • Streams refactor • Working directory now is a real working directory • UFFI has been adapted to Windows 64bit • “Plugin replacement program”: FreeType done • Windows 64bit VM closer and closer • VM has continued improving in several ways. • Specific plugins like FilePlugin for Windows !5
- 6. Pharo 8 !6 Coming Soon!!! Summer 2020 (Yes… because January is Summer)
- 7. Pharo 8 - Addressed • Analysis of File primitives performance on Windows • Support for multiple windows (SDL / GTK) • Headless VM (alpha) • Non-blocking FFI back-end • Degradation in performance • Tons of new tests !7
- 8. Under way for Pharo8 • Memory management and command line • Better Testing: Dr Test / Parametrized Tests / Parallel Execution • Better refactorings/eCompletion • Latency (Spotter and completion) large images • Quality rules on big classes/images • Spec 2.0 (new layout/widgets/transmission/backends) • Infrastructure for assembly generation (customization / shipping) !8
- 9. Plan for Pharo 9 • Better GC GC stops 2-3min for fullGC (in large images) • cmd+dot not working in all cases • Bloc • Parallel processing (not just parallel testing, which can be resolved at image side) • More more and more tests for the VM • Cleaner VM !9
- 10. Pharo Consortium • Handle the releases • Handle the infrastructure • Organize / guide / integrate the community • Financing Engineering / Documentation / Teaching efforts • 27 Industrial Partners • 19 Academic Partners !10
- 11. A Win-Win solution! • The engineers are paid by the contribution of the industrial partners. • Lifeware supports one year engineer • Schmidt supports one year engineer • …to improve Pharo infrastructure !11
