How to get/create a clean trunk image?
by Bernhard Pieber 22 Oct '17

22 Oct '17

Dear Squeakers, From time to time I would like to contribute to Squeak. What I need in that case is a current VM and a clean trunk image. I normally fetch the latter from http://files.squeak.org/6.0alpha and then update. I would like to use the 64bit version so that it gets more testing. However, the latest version Squeak6.0alpha-17412 is from 11 days ago and only available for 32bit. Any idea why this is the case? Another thing I notice is that some packages are dirty in that image: Services-Base BrowserProvider>>browserClassMenushortcut (changed) WorldMenuProvider>>worldpreferencesMenu (changed) BrowserProvider>>browserMethodMenushortcut (changed) WorldMenuProvider>>worldshortcut (changed) WorldMenuProvider>>preferencesMenuservicesBrowser (changed) WorldMenuProvider>>preferencesMenushortcut (changed) WorldMenuProvider>>browserMethodMenucreateNewService (changed) WorldMenuProvider>>preferencesMenupreferencesBrowser (changed) System Preferences class>>haloTheme (changed and recategorized) Preferences class>>sugarAutoSave Preferences class>>showAdvancedNavigatorButtons (changed) Preferences class>>enableVirtualOLPCDisplay Preferences class>>enablePortraitMode Tools Context>>inspectorClass (removed) I used the following script to print the above list: | result | result := Dictionary new. MCWorkingCopy allManagers do: [:each | | cleanSnapshot currentSnapshot patch | cleanSnapshot := each findSnapshotWithVersionInfo: each ancestors first. currentSnapshot := each package snapshot. patch := currentSnapshot patchRelativeToBase: cleanSnapshot. patch isEmpty ifFalse: [result at: each put: patch]]. result keysAndValuesDo: [:wc :patch | Transcript cr; show: wc packageName. patch operations do: [:each | Transcript cr; tab; show: each summary]] How can I get or create a clean trunk image to use for contributing? Is it save to revert those packages to the versions in trunk? Cheers, Bernhard

David T. Lewis uploaded a new version of System to project The Trunk: http://source.squeak.org/trunk/System-dtl.969.mcz ==================== Summary ==================== Name: System-dtl.969 Author: dtl Time: 20 October 2017, 8:14:14.736464 pm UUID: 701eefc3-8cfa-4085-8c10-e54dd4759ac2 Ancestors: System-dtl.968 Remove unreferenced instance variable #environment from class Project. In earlier versions of Squeak (see Squeak 3.6), this was part of a mechanism for supporting isolation layers, and there was a class Environment that is unrelated to our current implementation of Environments. Note that the current Environments implementation would permit the old class Environment to be loaded into a separate Environment. This is left as an exercise for the reader. =============== Diff against System-dtl.968 =============== Item was changed: Model subclass: #Project + instanceVariableNames: 'world uiManager changeSet transcript parentProject previousProject displayDepth viewSize thumbnail nextProject projectParameters version urlList lastDirectory lastSavedAtSeconds projectPreferenceFlagDictionary resourceManager' - instanceVariableNames: 'world uiManager changeSet transcript parentProject previousProject displayDepth viewSize thumbnail nextProject projectParameters version urlList environment lastDirectory lastSavedAtSeconds projectPreferenceFlagDictionary resourceManager' classVariableNames: 'AllProjects CurrentProject GoalFreePercent GoalNotMoreThan' poolDictionaries: '' category: 'System-Support'! !Project commentStamp: 'cbr 7/27/2010 21:36' prior: 0! A Project stores the state of a complete Squeak desktop, including the windows, and the currently active changeSet. A project knows who its parent project is. When you change projects, whether by entering or exiting, the screen state of the project being exited is saved in that project. A project is retained by its view in the parent world. It is effectively named by the name of its changeSet, which can be changed either by renaming in a changeSorter, or by editing the label of its view from the parent project. As the site of major context switch, Projects are the locus of swapping between the old MVC and the new Morphic worlds. The distinction is based on whether the variable 'world' contains a WorldMorph or a ControlManager. Saving and Loading Projects may be stored on the disk in external format. (Project named: 'xxx') exportSegment, or choose 'store project on file...'. Projects may be loaded from a server and stored back. Storing on a server never overwrites; it always makes a new version. A project remembers the url of where it lives in urlList. The list is length one, for now. The url may point to a local disk instead of a server. All projects that the user looks at are cached in the Squeaklet folder. Sorted by server. The cache holds the most recent version only. When a project is loaded into Squeak, its objects are converted to the current version. There are three levels of conversion. First, each object is converted from raw bits to an object in its old format. Then it is sent some or all of these messages: comeFullyUpOnReload: smartRefStream Used to re-discover an object that already exists in this image, such as a resource, global variable, Character, or Symbol. (sent to objects in outPointers) convertToCurrentVersion: varDict refStream: smartRefStrm fill in fields that have been added to a class since the object was stored. Used to set the extra inst var to a default value. Or, return a new object of a different class. (sent to objects that changed instance variables) fixUponLoad: aProject refStream: smartRefStrm change the object due to conventions that have changed on the project level. (sent to all objects in the incoming project) Here is the calling sequence for storing out a Project: Project saveAs Project storeOnServer Project storeOnServerWithProgressInfo Project storeOnServerInnards Project exportSegmentFileName:directory: Project exportSegmentWithChangeSet:fileName:directory: ImageSegment writeForExportWithSources:inDirectory:changeSet: !

a problem I am having with eLinda
by henry 21 Oct '17

21 Oct '17

I have a new version of eLinda in Cryptography. You can find it here: [http://www.squeaksource.com/Cryptography/elinda-HenryHouse.11.mcz](http://w… If you look into the test class ETupleSpaceTest #testEventual is failing because the tuple is resolved but the computation within the tuple is not yet resolved. Tuples seem to have 2 states: eventualComputing and resolved and the tuple itself should not be resolved until all internal computations are resolved. Should I create a special TuplePromiseERef or figure out how to resolve the initial tuple promise with an eventualComputing promise somehow? I think about it and I think that ETuple's need a special tupleResolver, but I am unsure how to lookup for the correct resolver in ETuple. Okay...I subclassed Etuple from ERef and am able to override ETuple class>>#resolverClass to use a special resolver to be worked upon. - HH
