Final rush for submitting GSOC proposal - Need your help
by Serge Stinckwich Feb. 9, 2017

Feb. 9, 2017

Hi all, we are currently working with Alexandre to submit the gsoc proposal to Google. I was a little bit busy with my lectures and I didn't check the current proposals available here: http://gsoc.pharo.org/ but all the projects are coming from RMOD team, but having all the projects proposal coming from the same place might be perceived negatively from Google. Can we add more projects from previous gsoc form other people also ? We have only one hour to polish the list. Thank you for your help. -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

Yes, thank you Stephan. I just add them ;-) I think we can change the list of projects until tomorrow.

Pharo 6 cannot parallel trace through same method
by Ben Coman Feb. 9, 2017

Feb. 9, 2017

This has bugged me a few times recently, so I've produced a demo. Define... Object subclass: #AA instanceVariableNames: '' classVariableNames: '' package: 'AAAA' AA>>test self haltOnce. self inform: 'I got here'. then in playground evaluate.... Halt resetOnce. "i.e. World > Debugging > Enable all break/inspect once." AA new test. and as expected you get a debugger window. Now once again without closing the debugger ... Halt resetOnce. AA new test. and I'd expect another debugger, but instead I'm informed 'I got here'. Its extremely useful sometimes to parallel trace through code comparing two cases, and the current behaviour prevents that. . The Pharo 5 equivalent works as expected... Halt enableHaltOnce. AA new test. I'm not sure where to hang it, but the following test differentiates between Pharo 5 & 6. (you can also run it from the playground.) testParallelTrace |completed p1 ds1 p2 ds2| completed := 0. Halt resetOnce. "enableHaltOnce" p1 := [ self haltOnce. completed := completed + 1 ] newProcess. ds1 := DebugSession named: 'Trace1' on: p1 startedAt: p1 suspendedContext. ds1 resume. Halt resetOnce. "enableHaltOnce" p2 := [ self haltOnce. completed := completed + 1 ] newProcess. ds2 := DebugSession named: 'Trace2' on: p2 startedAt: p2 suspendedContext. ds2 resume. self assert: (completed = 0) I've opened https://pharo.fogbugz.com/f/cases/19677/Cannot-parallel-trace-through-same-… cheers -ben P.S. I'm not sure if enabling the global haltOnce might cause issues. It would be useful to be able to set it only for the DebugSession.
