build validation shows wrong slice loaded
by Max Leske Jan. 27, 2014

Jan. 27, 2014

In 12259 I had validation warnings and so I went and looked at that page for the first time (pretty cool btw!). The problem with issue 12259 is now that there are multiple slices in there. The validation performed on the image has been done correctly with my version of the slice, but all the messages on the page say that itâs Damienâs slice (which doesnât contain the same code and would produce completely different results). So, my guess is, that the name is somehow being cached (?) or something. It would be nice to have the validation show the correct slice to avoid others spending the extra 20 minutes until theyâve figured it outâ¦ :) Cheers, Max

IDE reloading based on configuration
by Pavel Krivanek Jan. 27, 2014

Jan. 27, 2014

Hi, I transformed the Morphic reloading script into a configuration and it works :-) Jenkins job: https://ci.inria.fr/pharo-contribution/view/Pharo-Kernel-3.0/job/PharoKerne… Configuration repository: http://smalltalkhub.com/#!/~Pharo/SystemConfigurations/ it's named ConfigurationOfIDE. Small note, I must parse versions list from a string because the method has too many literals if I try to use standard form used in normal configurations generated by the tools. Cheers, -- Pavel

Fwd: [regression reporter]regression occurred
by Sven Van Caekenberghe Jan. 27, 2014

Jan. 27, 2014

Camillo (as you wrote this stuff), The test below often fails on the CI servers, timing tests are brittle there. Is this test necessary the way it is written now, what do you think ?

Integration Problem
by Sean P. DeNigris Jan. 27, 2014

Jan. 27, 2014

I followed the video directions to try and integrate a fix. Unfortunately, my startup script class got included in the update and broke the Jenkins build (which can't find the mcz). What do I do now? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Integration-Problem-tp4739543.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Roassal Visualization for control flow graph issues
by ClÃ©ment Bera Jan. 27, 2014

Jan. 27, 2014

Hello Roassal developers, A few time ago Usman Bhatti showed me Roassal. Today I decided to use it for my daily work on a project that aims to optimize Pharo's methods. Firstly I am quite impressed by the quality of Roassal, I am currently using the Roassal + Mondrian builder and I have a visual representation which is very close to what I want after 1 hour of work with the help of Usman. Good job guys. Here are 2 examples of what I use: exampleIfTrueIfFalse2 | a b | a := true. a ifTrue: [ false ifTrue: [ ^ b := 1 ] ifFalse: [ b := 2 ] ] ifFalse: [ true ifTrue: [ b := 4 ] ifFalse: [ b := 5 ] ]. ^ b [image: Images intÃ©grÃ©es 1] Here there's one rectangle for each basic block, entrance/exits are basic blocks with bigger borders, and borders in red represents the "hot path", which the path the execution flow most frequently uses (based on native code counters added at some spots in the method by Cogit). Another example: exampleToDo 1 to: 10 do: [ :i | self kick: i ] [image: Images intÃ©grÃ©es 3] Now I have a few issues with the layout. I am currently using the narrowTreeLayout which seems to be the best for my visualisation. *issue 1:* When branches merges, which is in a tree when a node has 2 or more parents, or when I have a #ifTrue:ifFalse:, the child is not well aligned horizontally. Here in the first visualisation I showed, BasicBlock 5 is below but not in the middle of Basic block 8,7 and 4 (horizontally). I put a minimal width for each basic block to make it better but it's still not perfect. *issue 2:* (most important issue) I cannot display back jumps because then all the graph is missdrawn, therefore I need to remember where they are instead of visualizing them all the time (I cannot display the back jump from basic block 3 to basic block 2 in the second representation. In addition, the back jump edge, when well displayed, overlaps the basic blocks visualizations. Here is an example of what I would like for the edges and basic block positions: [image: Images intÃ©grÃ©es 2] As you can see, here exit is in the middle of B2 and B5 horizontally, which is not the case in my roassal visualization. In addition, there's a back jump from B6 to B4 that I cannot display (or all the visual representation goes nuts). The edge for the back jump does not overlap with the basic blocks. In this graph, arrows follow a grid. I don't care that arrows are diagonals instead of a mix of horizontal and vertical lines but I would like to be able to see nicely the back jumps as in this graph. Do you have an idea on what layout/view options I could use with Roassal +Mondrian to have a better result ? I tried to create my own layout but after 2 hours I understood this cost too much time for my planning (or perhaps I'm just too dumb to do it fast :-( ). Anyway, the representation I have now is good enough for me to use it. But a better one would be better, especially for back jumps :-). Thanks for any help. Clement

Null Object Pattern
by Sean P. DeNigris Jan. 27, 2014

Jan. 27, 2014

I'm missing something here... I tried implementing: MyNullClass>>#ifNil: nilBlock ifNotNil: notNilBlock nilBlock value. But the notNilBlock is evaluated. I'm assuming it's being inlined. Is that right? How do I workaround? I also tried subclassing UndefinedObject, with the same result. Any ideas? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Null-Object-Pattern-tp4738574.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
