Version number difference between MC and GitFileTree
by Mariano Martinez Peck Jan. 3, 2016

Jan. 3, 2016

Hi Thierry, When I commit from MC, I see the generated commit, with something like OSSubprocess-MarianoMartinezPeck.7. However, when browse the repository later from MC, I get that such a commit is displayed as OSSubprocess-MarianoMartinezPeck.4 (the rest of the commit message maps correctly). Could this offset be because of the first initial 3 commits? That is, initial git commit from github, and 2 commits of "gitfiletree repository properties". Is there a workaround here so that both could map correctly? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

EyeInspector with subclasses of ProtoObject
by Esteban A. Maringolo Jan. 3, 2016

Jan. 3, 2016

I'm dealing with the MessageArchiver of GLORP which is a subclass of ProtoObject and handles the "transparent" creation of expressions vÃa a DNU resolution. The problem I'm facing is that the EyeInspector expects the value in its value holder to respond to #basicSize, and because MessageArchiver inherits from ProtoObject it doesn't understand it. The problem is here: EyeInspector>>#variableFieldsToShow "Answers the indexes of the variable fields of the object to show. Shorten the list for very long collection (cf limit1 and limit2)" |bSize| bSize := self objectVariableSize. ^ bSize <= (self limit1 + self limit2) ifTrue: [1 to: bSize] ifFalse: [(1 to: self limit1) , (bSize - self limit2 + 1 to: bSize)]. If I implement #basicSize in MessageArchiver things go bananas. If I doesn't, and because #objectVariableSize is sent to MessageAchiver "proxy", bSize ends up with an instance of the MessageArchiver instead of an integer. I implemented #inspectorClass in MessageArchiver class to return EyeBasicInspector, but it is the same. Question: Is it documented what I should define/override in my classes to support EyeInspector?

how to make a method inlined
by Ben Coman Jan. 2, 2016

Jan. 2, 2016

Since DelayScheduler runs very often at the highest priority, the desire is to have it highly optimised. One way to do this is put everything into a very long method to avoid the overhead of message sends. Another might be to keep it logical split into several method for readability, but have those methods in-lined. I'm sure how pragmatic doing that would be, but it sparked my curiosity.... how do you go about designating a method/message to be inlined. I see OCASTTranslator>>visitMessageNode: (presumably) calls RBMessageNode>>isInlined which does a bundle of checks, for example RBMessageNode>>isInlineIf checks (#(ifTrue: ifFalse: ifTrue:ifFalse: ifFalse:ifTrue:) includes: self selector) ifFalse: But there also seems to be an <inline> pragma per WarpBlt>>rgbMap:from:to: What are the trade-off between these approaches, particularly for the special case where a method may have only one sender, where code is broken into small "private" methods mainly for readability. Also, do you need to manually supply the inlined bytecode yourself? cheers -ben

Preview of new FFI?
by Pierce Ng Jan. 1, 2016

Jan. 1, 2016

Hi, (For Esteban perhaps...) Is there an image/VM combo to preview the new FFI? I just made NBSQLite3 work with SQLcipher (for transparent database encryption) but don't want to spend any effort refactoring if I need to redo for the new FFI. Pierce

Roassal2 in Pharo 5 -> segfault
by Johan Fabry Dec. 31, 2015

Dec. 31, 2015

Hi all, just in case this is not a known bug: Intensive use of Roassal2 in Pharo 5 causes a segfault of the mac vm. A crash.dump is attached. Itâs the vm I got just now ( wget --quiet -O - get.pharo.org/50+vm | bash ) and Pharo5 with Alexesâ 17280 slice to make Roassal visualize shapes correctly. To reproduce, all I need to do is have a visualization open with a layout animation and after some time it will crash. I use this in LRP and I can give easy steps to reproduce if needed. ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD and RyCh labs - Computer Science Department (DCC) - University of Chile
