curiousity, ensure unwind block priority inheritance
by Ben Coman Feb. 23, 2016

Feb. 23, 2016

Just thought I'd share something enlightening I learnt today, a curious surprise... When a process is terminated, the #ensure: unwind block effectively inherits the priority of the terminator process. Thus the following... log := OrderedCollection new. s := Semaphore new. p := [ [ log add: 1. s signal. log add: 4. ] ensure: [log add: 5] ] forkAt: 30. s wait. log add: 2. "p terminate." log add: 3. 100 milliSeconds wait. Transcript crShow: log. ...gives {1 2 3 4 5} as expected. However uncommenting the terminate statement produces {1 2 5 3}. Quite non-intuitive** to have the "5" code inside the priority 30 block execute before the "3" code of the priority 40 of the UI/Playground. **meaning it bit me for a few hours trying to understand some ProcessTests related to Case 17588. cheers -ben

double selection in the debugger is confusing
by stepharo Feb. 23, 2016

Feb. 23, 2016

Hi guy we should disable the double selection when we click on a stack element because we get selection in frame and in fill and this is confusing because the PC is represented by the filled one. Stef

TxText architecture question
by Stephan Eggermont Feb. 23, 2016

Feb. 23, 2016

In the TxText model, a text consists of a double-linked list of spans, containing the text content and its attributes. I wonder how to efficiently map a hierarchical text model (like that of Pillar) to that. Stephan

Why the GTSpotter help does not explain all the categories
by stepharo Feb. 23, 2016

Feb. 23, 2016

Hi So I tried again to understand how spotter works and I looked at the help and I could not understand how I can find class references. I saw that but it does not show me how I can use it and I do not really want to understand how this is implemented. spotterReferenceFor: aStep <spotterOrder: 30> aStep listProcessor title: 'References'; allCandidates: [ (SystemNavigation default allReferencesTo: self binding) collect: #compiledMethod ]; itemName: [ :method | method gtDisplayString ]; filter: GTFilterSubstring To me this help is totally obscure. Spotter allows the developer to define custom search processors in different classes. These custom processors take effect when Spotter reaches an instance of the extended class. You can find below the list of extensions from this image. You can also browse this list by inspecting: GTSpotter spotterExtendingMethods Behavior - Class instance variables (spotterClassInstanceVariablesFor:) - Composing traits (spotterCompositionFor:) - Instance variables (spotterInstanceVariablesFor:) -
