Re: [Pharo-project] MorphicModel needs serious cleaning

by Schwab,Wilhelm K

After SmartReferenceStream, nothing surprises me :) Seriously, debuggers in front of end users and centralizing all of the conversion methods in SRS itself, rather than with the class of the object being converted. On the topic at hand, there is a lot of room to make clean use of events. One thing to watch: Dolphin makes a point of introducing comparison policies, and has some "silent" setters (that do not trigger events). I have long suspected that they are at least in part intended as a damping mechanism to avoid meltdowns that might have occurred in Dolphin's "youth."

[Pharo-project] Socket objects created twice ?

by Sven Van Caekenberghe

Hi All, I encountered something that I do not understand. I tried this in 1.2.2 and 1.4 with both my normal, older CogVM as well as the lastest one by Estaban. In a normal clean image, there would be not Socket instances. Socket allInstances size = 0 Now create any kind of Socket Socket new (or newTCP, newUDP) Now Socket allInstances size = 2 So Smalltalk reports two instances, but it seems they share the same socketHandle and semaphores, so one seems to be a shallow copy of the other. (Close the one instance, 3 timesRepeat: [ Smalltalk garbageCollect ] and they are both gone). Is this normal ? Is there really only one OS level socket ? Does this have to do with Sockets being in a WeakRegistry ? It is confusing to say the least. Sven

As Igor said, I cannot see anything weird in the dump. Someone someone knows in the VM mailing list.

Re: [Pharo-project] Jenkins: build scripts are now in public repository

by Mariano Martinez Peck

Hi Igor. I was looking in the scripts and I found that the version of Pharo1.4 is "hardcoded": https://gitorious.org/pharo-build/pharo-build/blobs/master/pharo-shell-scri… Maybe you can get it from a static url like http://www.pharo-project.org/pharo-download/unstable-core or fetch the previous (successful ?) one from hudson?

Re: [Pharo-project] keymappings question

by Tudor Girba

Hi, Ahh, I thought that the latest version of Keymappings handles shortcuts per morph instance. It looks like it does not, and this is bad news for me :(. I want to use them in the context of Glamour and for that I need to control the shortcuts of morph instances. How difficult is it to get it working?

[Pharo-project] MorphicModel needs serious cleaning

by Igor Stasenko

Just found that scrollbars are assigned 'slotname' when you creating them and when it comes to send events to their model, it end up in this method: use: cachedSelector orMakeModelSelectorFor: selectorBody in: selectorBlock | selector | model ifNil: [^ nil]. cachedSelector ifNil: ["Make up selector from slotname if any" selector := (slotName ifNil: [selectorBody] ifNotNil: [slotName , selectorBody]) asSymbol. (model class canUnderstand: selector) ifFalse: [(self confirm: 'Shall I compile a null response for' , Character cr asString , model class name , '>>' , selector) ifFalse: [self halt]. model class compile: (String streamContents: [:s | selector keywords doWithIndex: [:k :i | s nextPutAll: k , ' arg' , i printString]. s cr; nextPutAll: '"Automatically generated null response."'. s cr; nextPutAll: '"Add code below for appropriate behavior..."'.]) classified: 'input events' notifying: nil]] ifNotNil: [selector := cachedSelector]. ^ selectorBlock value: selector this is incredible.. -- Best regards, Igor Stasenko AKA sig.
