Re: [squeak-dev] Wrong method source pointer in Squeak5.2

(resending because of wrong subject, sorry) Hi Dave, I just retested loading in Ubuntu 17.04 (32-bits) without problems. Maybe you didn't checkout the commit I referenced? I realise there's a `cd Seaside` missing before the `git checkout`. What's the load error about? What system are you using exactly?

Wrong method source pointer in Squeak5.2
by Max Leske 16 Dec '18

16 Dec '18

Hi, We have an issue in Seaside where a loaded test method holds a bad source pointer. We only noticed because this method accesses the debugger map. How to reproduce: 1. clone SmalltalkCI: git clone git@github.com:hpi-swa/smalltalkCI.git 2. clone Seaside: git clone git@github.com:SeasideSt/Seaside.git; git checkout 9cb54a7b14cd254ef318294905c4e8dda8dd9f79 3. install Seaside in Squeak5.2: <path to SmalltalkCI>/run.sh --headful -s Squeak-5.2 <path to Seaside>/.smalltalk.ston 4. Run the test WAPharoDebuggerTest>>testNamedTempAt and you'll see a debugger pop up for an UndeclaredVariable. The source lookup is performed in the changes file but in the middle of a chunk of binary (font) data. I can can only speculate that some of that binary data introduces random chunks which messes with the offsets. We're adding a workaround for that particular test for now. Let me know if I can help track down the issue. Cheers, Max

Scraping Squeak Wiki into 6000+ subclasses of Doclet overloads the Browser
by gettimothy 16 Dec '18

16 Dec '18

Hi folks, just an FYI and not a problem per-se. I don't know if keeping thousands of classes hanging around is a valid use-case, but I figured I would give it a try to see what happened as a first-stab at in-image persistence for the live SWiki. For SeasideDoc ( http://menmachinesmaterials.com/SeasideDoc ) under SWIKI in the left menu, I have scraped the live wiki and stored the pages as subclasses of DocletSwiki (?) The package requires Seaside and Zurb and is available at the menmachinesmaterials.com via anonymous ftp. The application works just fine. I have installed on the latest Squeak5.2 and there is no stray junk in the image per: 'http://wiki.squeak.org/squeak/2176' SystemNavigation obsoleteClasses SystemNavigation obsoleteBehaviors SystemNavigation obsoleteMethodReferences Smalltalk garbageCollect Everything works fine until I attempt to browse the superclass of those 6000+ subclasses. From a Browser, Find Class -> Doclet Then, the image, while not hanging, spikes to 100 percent on the attempt to browse. After about 5 minutes, the browser opens on the thing, but it is clearly churning on the scenario. When I close/minimize the Browser or change to a different project, performance returns to normal. I don't know if keeping thousands of classes hanging around is a valid use-case, but I figured the team would like to know about it purely as an intellectual curiosity. Cordially, t

Re: [squeak-dev] stepTime and wantsSteps

I think they should both be in "updating". But what is a "presenter"? I don't recognize that as a Morphic term at all...
