CI: find user from FogBugz event

by Tommaso Dal Sasso

Hi guys, I was looking at the Continuous Integration services code at http://smalltalkhub.com/#!/~Pharo/ci to extract information from the FogBugz tracker. I noticed that the FogBugzCase and FogBugzEvent classes do not contain the user that performed the action, except for some plain text inside the "description" field. Is there a way to extract the FogBugz user associated with an event? Thank you Tommaso Dal Sasso

Re: [Pharo-users] Cannot be recompiled

by Martin Dias

Hi, (forwarded from pharo-users) Object subclass: #A instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Unclassified'. (Smalltalk at: #A) subclass: #B instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Unclassified'. Object variableSubclass: #A instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Unclassified'. I'm working in the "new class builder" [1]. It automatically propagates this format change to the subclasses, instead of raising the error like the current class builder does. ie, the class B becomes variable when A becomes variable. Do you agree?

Re: [Pharo-users] Spec and e.g. hResizing:

by Benjamin

Here shrinkWrap will not work since the SpecLayout defines an absolute layout for every widget. Moreover it's a bit weird since you then specify the height of the column :) If you want to tackle (a bit) this problem ,you may use extent: to do something Adding different layout would also be a solution, but it will require some work :) Ben On Apr 24, 2013, at 12:36 AM, Sean P.

Two things: - you cannot delegate the waiting on the delay to the timer instance even though that is more elegant: the problem is that then the timer instance will be on the stack during the wait, which is a strong reference, hence the timer does not become garbage (unless you happen to intervene in-between 2 waits ;-) - you cannot call #start from an inspector, that seems to create a reference from a NOCController to the inspector instance and to the timer which is being inspected; this reference remains when the inspector closes, this is again a strong reference, hence the timer does not become garbage I am not sure, but the 2nd point feels like a (potentially serious) bugâ¦ Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill
